As we enter the eighth year of the UAHSJ, we are excited to<br />
announce a number of changes. Two thousand and eleven was<br />
a transition year for the journal, with two major initiatives in<br />
the works. Emphasizing multidisciplinary involvement is an<br />
ongoing priority, and in the coming years we hope to continue<br />
this momentum by including other health sciences faculties<br />
and schools at the University of <strong>Alberta</strong>. We have reinstituted<br />
Faculty Representatives to aid in better distributing the journal<br />
and, most importantly, solicit even more submissions from<br />
the talented writers and researchers in our student body. On<br />
a similar note, we also look forward to working with other<br />
universities across Canada to widen both our readership and<br />
submissions base.<br />
There have been a number of content changes in the works at<br />
the UAHSJ. Beginning with this issue, we will focus on pieces<br />
geared towards a general health sciences reader: clinical and<br />
scientific reviews, summer student abstracts, book reviews,<br />
history of medicine pieces, medical education research,<br />
personal reflections, and letters. Our hope is that this will<br />
complement the push for more multidisciplinary involvement.<br />
Of course, none of this would be possible without the tireless<br />
efforts of the Journal’s contributors, our Editorial Board, and<br />
our new Junior Editor, Andrew Tang. We extend our thanks<br />
to the Faculty of Medicine and Dentistry for their generous<br />
financial support, and Dr. Fraser Brenneis, Vice-Dean of<br />
Education, who took the time to guide and advise us through<br />
the publication of this issue. Finally, we would like to warmly<br />
welcome Dr. Tamar Rubin, a PGY-1 resident in Pediatrics, who<br />
has assumed the role of Editor of Musa. Tamar has extensive<br />
experience in both literary writing and the medical humanities.<br />
Many thanks to Dr. Pamela Brett-MacLean, who originally<br />
conceived Musa and will now carry on as its Faculty Editor.<br />
Yours,<br />

Abstract<br />
The Objective Structured Clinical Examination (OSCE) is the<br />
primary modality for testing clinical skills throughout medical<br />
school and in residency training. This article explores the difficulties<br />
of the exam via the subjective perspective of a student in the<br />
system, commenting on reticent standardized patients, the lack<br />
of consensus on what makes an ideal medical student and the<br />
absence of feedback. As the exam celebrates nearly four decades in<br />
use, it is important that we continue to evaluate its usefulness and<br />
brainstorm innovative approaches to advancing the state of clinical<br />
examinations.<br />
The Objective Structure Clinical Examination (OSCE) has rapidly<br />
become the leading clinical examination in North American Medical<br />
Schools. The unassailable champion of repetitive and reproducible<br />
evaluation, it has become the envy of all other tests. While multiple<br />
choice still holds a prominent position in most medical curricula,<br />
that is usually for the convenience of administering the test and the<br />
sheer volume of information one can sift through. As a learner, one<br />
has had ample time to exploit the system, mastering the nuances of<br />
the “all of the following EXCEPT” and “which answer is the BEST”<br />
questions. In reality, we have been asked this type of question since<br />
kindergarten and the PBS specials we grew up on sang “one of these<br />
things is not like the other one.” 1<br />
The OSCE is succinctly explained in the abstract of a 1975 BMJ article:<br />
“the examination is more objective and a marking strategy can be<br />
decided in advance.” 2 The veracity of the latter half of this requirement<br />
is evidenced by the rubric style approach of many modern OSCEs.<br />
However, the first part is where the interesting dilemma lies. Is the<br />
examination more objective? From the subjective experience of<br />
students, it would hardly seem so.<br />
The variability lies in the innate qualities of both the “standardized<br />
patient” and the examiner. Having worked as a standardized patient,<br />
the instructions one often receives is to be as guarded as possible<br />
about information, refraining from volunteering details unless<br />
specifically probed. This is in direct contrast to the guidance offered<br />
in basic history taking skills, where students are counselled to allow<br />
the patient to convey the narrative of their illness uninterrupted. For<br />
those that have participated in OSCEs, it is easy to recall those actors<br />
from whom information had to be stolen as if it were precious gems.<br />
From many a station I have walked out and, in conversation with<br />
my peers in different tracks, realized that another “standardized”<br />
patient had been much more forthcoming with a pivotal piece of the<br />
diagnostic puzzle.<br />
In Rowntree’s 17 proposals for better assessment, he notes that<br />
“there is an assumption rampant in talk of academic standards,<br />
that all qualified assessors feel, understand and judge in much the<br />
same way when confronted with the work of a particular student.<br />
It is presumed that they would notice and value the same skills and<br />
qualities and would broadly agree in their assessments. Abundant<br />
evidence attests to the falsity of such assumptions.” 3 In the same<br />
2<br />
way, examiners vary widely in their preferences of what they believe<br />
makes the ideal learner. One need only glance at the complicated<br />
medical admission system or the behemoth that is the Canadian<br />
Resident Matching Service (CaRMS) to realize that we cannot agree<br />
on the perfect model student, yet we continue to cling to antiquated<br />
standards so as to maintain a united front. Despite the broad<br />
accusations suggesting poor inter-rater reliability across a variety<br />
of domains, 4 OSCE examinations remain a mainstay of evaluation<br />
despite their artificial construction and potentially variable<br />
environment.<br />
In the same seminal article, the authors proclaim that the<br />
“examination results in improved feed-back to students and staff.” 2<br />
This may hold true for the teaching OSCEs, where 2 minutes of<br />
personalized commentary follows each station, but for the majority<br />
of exams in medicine, the results are protected and not released. So<br />
while occasionally one may receive a grade or score sheet, one is<br />
left waiting for the commentary that can enhance clinical skills or<br />
refine an approach. The majority of instructors emphasize the need<br />
to train physicians, not test takers, yet the very nature of receiving a<br />
pass or a fail undermines the learning process. Research has shown<br />
that overall, detailed, descriptive feedback was found to be most<br />
effective when given alone, unaccompanied by grades or praise, the<br />
direct opposite of what students usually receive. 5 The OSCE has<br />
significant advantages over multiple choice questions, providing a<br />
rich opportunity for students to simulate patient encounters and<br />
maintain some degree of standardization. However, it’s limitations<br />
and shortcomings should be discussed, rather than disputed. The<br />
modern OSCE, nearly 40 years after its rise to prominence, seems<br />
stagnant in the face of the rapid change in the medical community.<br />
Perhaps as we enter a new decade of medical education we can<br />
critique our instruments, as well as our students, and develop<br />
innovative models to evaluate competence in clinical skills.<br />

University of <strong>Alberta</strong> Summer Students’ Research Day<br />
In 2011, over 200 undergraduate students participated in the Faculty of Medicine & Dentistry Summer Student<br />
Research Program. On October 15, 175 students presented posters at the 44th Annual Summer Students’ Research<br />
Day. Listed below are the 14 finalists from the poster competition. We congratulate the finalists and all participants.<br />
From these 14 finalists, two students were selected to represent the<br />
University of <strong>Alberta</strong> at the annual National Students’ Research<br />
Forum in Galveston, Texas. Their abstracts are presented below.<br />
Uncovering the role of topoisomerase II-beta<br />
binding protein 1 in dna replication stress response<br />
Mark Assmus, Charles Leung, Mark Glover<br />
DNA replication stress can lead to genomic instability which has<br />
been shown to be one of the primary hallmarks of cancer. TopBP1 is a<br />
crucial mediator protein found within the replication stress response<br />
in mammalian cells. TopBP1 activates Ataxia telangiectasia mutated<br />
related (ATR) kinase which phosphorylates many of the downstream<br />
substrates to initiate this response. The replication stress response<br />
involves specific interactions between the nine BRCA1 C terminus<br />
(BRCT) domains of TopBP1 and various proteins. More specifically,<br />
TopBP1 has been shown to provide an essential role in interacting<br />
with both ATR-interacting protein (ATRIP), Rad9-Rad1-Hus1 (9-1-1)<br />
complex as well as Mediator of DNA damage checkpoint protein 1<br />
(MDC1) which are all essential components of the response pathway.<br />
The crystal structure of TopBP1 BRCT 4/5 in complex with MDC1 was<br />
previously solved in our lab. The structure shows a unique mode of<br />
TopBP1 binding to MDC1 that involves the dimerization of two BRCT<br />
4/5 molecules. In an effort to further examine this interaction, I used<br />
a fluorescence polarization (FP) binding assay involving an MDC1<br />
FITC labelled di-phospho-peptide. I was able to express and purify<br />
GST fusion proteins of TopBP1 BRCT 4/5 and TopBP1 BRCT 5, as well<br />
as TopBP1 BRCT 5 alone, which were used for further FP studies.<br />
The results of the FP assays indicated that it is the BRCT 5 binding<br />
pocket which is primarily responsible for the interaction with MDC1<br />
and that the dimerization induced by GST allows for tighter binding.<br />
Additionally, mutant constructs of the putative BRCT 5 binding<br />
pocket were designed, successfully over-expressed and purified.<br />
The FP assays showed decreases in binding affinity associated with<br />
mutation of key conserved residues in the binding pocket. FP was<br />
also used to confirm that the phosphorylation of the MDC1 peptide<br />
is essential for TopBP1 BRCT 4/5 recognition. Taken together, these<br />
FP results further support the unique dimerization-based binding<br />
mechanism suggested by the crystal structure.<br />
PaX3 expression in melanoma<br />
Zachary Tan and D. Alan Underhill<br />
The transcription factor PAX3 is critical for development of neural<br />
crest lineages including melanocytes. Prior to birth, PAX3 is<br />
required for the proliferation of melanocyte precursors and it is<br />
thought to maintain an ‘undifferentiated plastic state’ in epidermal<br />
melanocytes after birth, as well in melanocyte stem cells. In<br />
addition, PAX3 is expressed throughout melanoma progression,<br />
from nevi to metastatic disease. Nevertheless, little is known about<br />
how PAX3 carries out these diverse roles. PAX3 is reported to be<br />
phosphorylated by Glycogen Synthase Kinase 3ß (GSK3ß). In the<br />
present study, the potential role of this kinase in modulating PAX3<br />
activity in B16F10 melanoma cells was examined using chemical<br />
inhibitors. Fluorescence Activated Cell Sorting (FACS) was used<br />
to assess cell cycle distribution and PAX3 levels were monitored<br />
by immunoblotting. Treatment of cells with the GSK3ß inhibitors<br />
lithium chloride (LiCl) or BIO caused decreased cell proliferation<br />
(P=0.05) and G2/M accumulation (P=0.05), and was associated<br />
with increased PAX3 expression (P=0.05). In contrast, knockdown<br />
of PAX3 using siRNA resulted in G1 accumulation (P=0.05).<br />
Immunofluorescence techniques for exogenous BrdU incorporation<br />
and endogenous PS10H3 allowed for direct microscopic visualization<br />
and quantification of cells in S and G2/M phase respectively. Upon<br />
PAX3 knockdown, there was significantly less BrdU incorporation<br />
and PS10H3 staining (P=0.05). Lastly, cell motility assays were<br />
conducted using live-cell Differential Interference Contrast (DIC)<br />
microscopy and analyzed using T-Scratch software. Interestingly,<br />
inhibition of GSK3ß as well as PAX3 knockdown was associated<br />
with markedly decreased cellular motility and proliferation. These<br />
investigations identify GSK3ß and as an important modulator of<br />
PAX3 levels in melanoma cells, and also suggest broader roles for<br />
PAX3 in regulating the G1 to S-phase transition in melanoma.<br />

ABSTRACT<br />
In the anterior cruciate ligament (ACL)<br />
transected knee, the medial collateral<br />
ligament (MCL) incurs numerous<br />
physiological changes that include<br />
inflammation and increased angiogenic<br />
activity resulting in functional deficiency.<br />
Peroxisome proliferator activated receptor -<br />
γ(PPAR-γ) agonists show promising results<br />
for their possible use in osteoarthritis<br />
therapies, but there are limited studies<br />
looking at their effects in this area. The<br />
purpose of this study was to examine the<br />
effect the PPAR-γ agonist rosiglitazone<br />
has on the angiogenic response in the<br />
osteoarthritic rabbit model. Six rabbits were<br />
assigned to one of three groups: control<br />
(n=2); 4-week right leg ACL transected<br />
(ACL-X) (n=2); 4-week right leg ACL-X<br />
treated with 5 mg/kg per day of rosiglitazone<br />
(n=2). The two contralateral MCLs in<br />
the 4-week ACL-X rabbits treated with<br />
rosiglitazone were also used as the drug<br />
treated non-ACL transected leg control. In<br />
total 8 MCLs were analyzed. To measure<br />
the blood vessel volume and angiogenic<br />
response in the MCLs, the vascular<br />
endothelium (CD-31) and vascular smooth<br />
muscle (SMA) volumes of them were<br />
determined. In the ACL-X rosiglitazone<br />
treated MCL, CD-31 volume decreased<br />
3-fold down to control levels, in comparison<br />
to non-treated ACL-X MCLs. Rosiglitazone<br />
had a significant effect on SMA, causing<br />
decreased volume in comparison to non –<br />
treated MCLs. In summary, rosiglitazone<br />
has a significant effect on the angiogenic<br />
response in the ACL ruptured animal model.<br />
INTRODUCTION<br />
Joint injury and arthritis are major causes<br />
of morbidity in the United States. One<br />
of the most clinically important ligament<br />
injuries that occur is to the anterior cruciate<br />
ligament (ACL). Each year in the USA, there<br />
are 80,000 surgical ACL reconstructions<br />
performed. 1, 2 Patients possessing ACL<br />
ruptures often complain of recurring loss<br />
of joint stability that often leads to the<br />
4<br />
premature onset of osteoarthritis, the<br />
most common type of degenerative joint<br />
3, 4 disease.<br />
In the knee, ACL rupture results in anterior<br />
translation of the tibia in relationship<br />
to the femur resulting in joint laxity<br />
(Figure 1). This abnormal biomechanical<br />
environment in an ACL ruptured knee is<br />
not only detrimental to cartilage health, but<br />
induces a series of adaptive structural and<br />
physiological changes in secondary joint<br />
stabilizing structures. There is angiogenesis,<br />
hyperaemia, inflammation and increased<br />
cellularity in the ligaments, meniscus,<br />
capsule and synovium of the knee joint. 5-7 In<br />
the medial collateral ligament (MCL) there<br />
is increased blood flow, increased DNA and<br />
RNA synthesis and cellularity7-10 Due to<br />
the properties of the MCL being degraded,<br />
this leads to further cartilage degeneration<br />
and altered joint mechanics in the ACL<br />
ruptured knee. 11<br />
There is limited information available on<br />
how this physiological adaptation occurs.<br />
The modification of adaptive changes in<br />
osteoarthritic tissues has the potential to<br />
provide new information on underlying<br />
mechanisms, leading to new therapies for<br />
osteoarthritis. The peroxisome proliferator<br />
–activated receptors (PPAR) agonist drugs<br />
show great promise in this area as a<br />
potential therapeutic treatment.<br />
PPAR agonists are ligand activated<br />
transcription factors that are part of the<br />
nuclear hormone super family. 12 Three<br />
different isotypes have been identified:<br />
PPAR-α, PPAR-β and PPAR-γ. These<br />
PPAR endogenous ligands form a diverse<br />
group of fatty acids with their derivatives<br />
generated by lipid metabolism. 12 Recently,<br />

University of <strong>Alberta</strong> Health Sciences Journal • April 2012 • Volume 7 • Issue 1
it has been found that PPAR-γ agonists are<br />
involved in vascular biology, inflammatory<br />
responses, tissue repair, cell differentiation<br />
and proliferation. 12-15 In arthritic<br />
synoviocytes, PPAR-γ agonists greatly<br />
inhibit inflammatory cytokine expression. 16<br />
PPAR-γ agonists have also been expressed in<br />
human chondrocytes acting as a protective<br />
17, 18<br />
mechanism for cartilage.<br />
PPAR-γ agonists have therapeutic potential<br />
in a variety of clinical conditions. There is<br />
literature showing PPAR-γ agonists role in<br />
fat metabolism and their anti-inflammatory<br />
actions shown through their effect on<br />
inhibiting cytokine expression. 19, 20 There<br />
are limited published studies looking at the<br />
effect of PPAR-γ agonists in osteoarthritis<br />
models. One study by Kobayashi et al.,<br />
using a partial medial menisectomy<br />
guinea pig model, found that the PPAR-γ<br />
agonist pioglitazone reduced cartilage<br />
lesion depth and area. 21 By studying the<br />
effect of the PPAR-γ agonist rosiglitazone<br />
on the adaptive physiological response<br />
in ACL ruptured knees (specifically the<br />
angiogenic activity), its potential as a new<br />
therapy to treat osteoarthritic patients can<br />
be determined.<br />
The purpose of this study is to examine the<br />
effect of the PPAR-γ agonist rosiglitazone on<br />
the physiological and angiogenic responses<br />
in the rabbit model of joint laxity and<br />
osteoarthritis. The rabbit model was chosen<br />
as we can compare the results obtained<br />
to our established database on adaptive<br />
physiology in rabbit ACL – ruptured joints.<br />
It is hypothesized that PPAR-γ agonists<br />
will decrease physiological degeneration<br />
of the MCL in the ACL ruptured knee.<br />
The blood vessel volume and degree of<br />
angiogenesis occurring in the MCL of the<br />
ACL ruptured knees will be measured using<br />
immunohistochemistry for specific markers<br />
for vascular endothelium (CD-31) and<br />
vascular smooth muscle (SMA) in the MCL.<br />

Zealand white rabbits (4.5 - 6.5kg; Riemans<br />
Fur Ranch, St. Agatha, Ontario) were<br />
assigned to one of three groups: control<br />
(n=2); 4-week right leg ACL transected<br />
(ACL-X) (n=2); 4-week right leg ACL-X<br />
treated with a low dose of 5 mg/kg /day of<br />
rosiglitazone (n=2). The two contralateral<br />
MCLs in the 4-week ACL-X rabbits treated<br />
with rosiglitazone were used as the drug<br />
treated non-ACL ruptured leg controls. This<br />
results in a total of 8 MCLs analyzed in this<br />
study. Rabbits were kept on a 12 – hour<br />
light/dark cycle and fed standard laboratory<br />
chow and tap water ad libitum. All animals<br />
were treated and maintained according<br />
to the Canadian Council on Animal Care<br />
guidelines and this study received approval<br />
by the University of Calgary Faculty of<br />
Medicine Animal Care Committee.<br />
aCL transection and<br />
Rosiglitazone injections<br />
Rabbits were given 0.18 mL of acepromazine<br />
maleate (Atravet ®) intravenously and<br />
anesthetized with halothane (2-5%, 1.0 L/<br />
min O ). All ACL transection surgeries were<br />
2<br />
completed on the right leg of the rabbits.<br />
An anterior tibial draw test was performed<br />
on the right leg to ensure no prior ACL<br />
injury existed. The anterior tibial draw test<br />
was done by grasping the tibia with both<br />
hands below the joint line, thumbs placed<br />
on either side of the patella, with the tibia<br />
pulled anteriorly.<br />
An antero-lateral surgical approach was<br />
used. The ligament was exposed by lateral<br />
subluxation of the patella and reflection<br />
of the intra-articular fat pad. The ACL was<br />
isolated using a hooked probe and the<br />
ligament was transected at the middle with<br />
a #12 hooked blade. A second anterior<br />
tibial draw was performed to ensure the<br />
transection was complete. Following the<br />
unilateral surgery, rabbits were treated with<br />
standard antibiotics and allowed to resume<br />
normal cage activity for four weeks.<br />
Rosiglitazone treated animals were injected<br />
subcutaneously with a low dose of 5 mg/<br />
kg of body weight per day for a total of four<br />
weeks. In the ACL-X rabbits, injections<br />
began on the day following the ACL<br />
transection surgery. Since the contralateral<br />
MCL was used as the non-operated leg<br />
rosiglitazone treated control, the 4-week<br />
drug treatment was simultaneous. At the<br />
beginning and end of the 4-week dosing<br />
period, anterior tibial draw tests were<br />
completed on the left leg to ensure no ACL<br />
injury existed.<br />
Immunohistochemistry<br />
MCLs were sectioned and labeled for CD-31<br />
and SMA according to the following doublelabel<br />
protocol. Rabbits were euthanized then<br />
the MCLs were harvested from control, ACL<br />
ruptured and rosiglitazone treated knees<br />
then cleaned of any extra tissue. Tissues were<br />
cryopreserved in serial sucrose solutions<br />
of 10%, 20% and 30% concentrations.<br />
Following cryoprotection, ligaments were<br />
frozen in isopentane at -80°C, embedded<br />
in OCT media then stored at -30°C for one<br />
month until processing. MCLs were cut into<br />
100 μm thick longitudinal serial sections and<br />
placed individually in 24 well plastic plates.<br />
Sections were washed in phosphate buffered<br />
saline (PBS) (3 x 10 minutes) then immersed<br />
in 10% normal donkey serum (Jackson<br />
Immunoresearch, West Grove, PA, USA)/<br />
PBS 1% Triton X100 for 1 hour at room<br />
temperature. MCLs were then incubated<br />
with mouse anti-human CD-31 antibody<br />
(1:50 dilution; Dako, Carpinteria, CA, USA)<br />
for 24 hours at 4°C in a humidified chamber.<br />
Sections were washed in PBS (3 x 10<br />
minutes) and incubated with donkey antimouse<br />
Cy5 conjugated secondary antibody<br />
(1:300 dilution; Jackson Immunoresearch,<br />
West Grove, PA, USA) for 2 hours at room<br />
temperature. Sections were washed in<br />
PBS (3 x 10 minutes) then incubated with<br />
goat anti-human smooth muscle actin<br />
(SMA) antibody (1:400 dilution, Novus<br />
Biologicals, Littleton, CO, USA) for 24 hours<br />
at 4°C, followed by further PBS washes<br />
and incubation with donkey anti-goat Cy2<br />
conjugated antibody (1:400 dilution; Jackson<br />
Immunoresearch, West Grove, PA, USA)<br />
for 2 hours at room temperature. Sections<br />
were then washed for a final time, placed<br />
on slides with Fluorsave TM (Calbiochem,<br />
Mississauga, Ontario) and coverslipped.<br />
Slides were stored in a cardboard slide<br />
holder to protect fluorescence loss due<br />
to light.<br />
Confocal Microscopy<br />
MCL sections were analyzed using an<br />
Olympus Fluoview FV-1000 confocal<br />
microscope. They were visualized under a<br />
10x objective and imaged using 4-micron<br />
thick optical z-stack sections. Simultaneous<br />
dual channel scanning laser confocal<br />
analysis was performed using preconfigured<br />
Cy2 and Cy5 channel settings. Images were<br />
saved in the OIF file format.<br />
Statistical analysis<br />
The CD-31 and SMA volumes found in<br />
the MCL were determined using Image<br />
J software. The volumes of CD-31 and<br />
SMA in each image were put into an excel<br />
spreadsheet and then summed together to<br />
get a total volume converted into milliliters<br />
for each ligament. The volumes of CD-31<br />
and SMA for each MCL type had their<br />
averages calculated. Since there are only two<br />
subjects per group, the mean and the range<br />
of data was the chosen method of statistical<br />
analysis. If the subjects in each group had<br />
increased numbers, inferential analysis<br />
using a two – way ANOVA would have been<br />
preferred for comparative purposes. By using<br />
this method of analysis, one could then<br />
interpret if rosiglitazone has an effect on the<br />
angiogenic response in this pilot study.<br />

RESULTS<br />
To quantify the blood vessel volume and<br />
the angiogenic response in the MCL of<br />
normal, ACL ruptured and rosiglitazone<br />
treated knees the CD-31 and SMA volumes<br />
were determined. Figure 2 shows that in<br />
control (non-drug treated) animals, MCL<br />
CD-31 volume ranged from 0.077 mL to<br />
0.118 mL with an average of 0.097 mL. CD-<br />
31 volume ranged from 0.291 mL to 0.307<br />
mL with an average of 0.299 mL in the<br />
MCL of ACL transected knees (Figure 2).<br />
In the rosiglitazone treated unoperated<br />
leg MCL, CD-31 volume ranged from<br />
0.077 mL to 0.131 mL with an average of<br />
0.104 mL (Figure 2). In the ACL transected<br />
rosiglitazone treated MCL, CD-31 volume<br />
averaged 0.119 mL and ranged from 0.099<br />
6<br />
mL to 0.139 mL (Figure 2). Thus, the 3-fold<br />
increase in CD-31 volume of the MCL in<br />
the ACL transected knees was mitigated by<br />
treatment with rosiglitazone.<br />
To further quantify the angiogenic response<br />
the volume of SMA was measured. Figure 3<br />
shows that in control (non-drug treated)<br />
animals, MCL SMA volume ranged from<br />
0.128 mL to 0.153 mL equating to an<br />
average of 0.141 mL. In the ACL transected<br />
knee the average SMA volume was 0.191<br />
mL and ranged from 0.162 mL to 0.221<br />
mL (Figure 3). In the rosiglitazone treated<br />
animals, unoperated leg MCL SMA volume<br />
average was 0.037 mL and ranged from<br />
0.029 mL to 0.045 mL (Figure 3). In the ACL<br />
transected rosiglitazone treated MCL, SMA<br />
volume average was 0.050 mL and ranged<br />
Figure 2. Mean vascular endothelium volume and range in the MCL. There is a 3-fold increase in vascular<br />
endothelium volume in the ACL transected non- drug treated knee MCLs as compared with control and<br />
rosiglitazone treated MCLs.<br />
Figure 3. Mean vascular smooth muscle volume and range in the MCL. In the ACL transected knee MCL<br />
and control knee MCL, there is a 4 and 3 fold increase respectively for vascular smooth muscle volume as<br />
compared to rosiglitazone treated MCLs.<br />
from 0.049 mL to 0.051 mL (Figure 3). This<br />
represents an approximate 4-fold increase<br />
in SMA volume in the ACL ruptured<br />
knee MCL over control and rosiglitazone<br />
treated MCLs.<br />
DISCUSSION<br />
ACL rupture causes numerous<br />
morphological and histological changes in<br />
human cartilage which includes osteophyte<br />
formation, increased surface roughening,<br />
increased tissue water content, increased<br />
cellularity, collagen fibril organization and<br />
biochemical alterations. 22-29 In addition<br />
to the detrimental changes to cartilage<br />
health, there are a number of structural<br />
and physiological adaptations found in<br />
secondary joint stabilizing structures in<br />
the knee. In the MCL, this has included<br />
increased DNA and RNA synthesis,<br />
increased blood flow, cellularity and scar<br />
like tissue formation. 7-10 All of these changes<br />
result in significant long-term consequences<br />
for the human patient that includes<br />
considerable pain, degenerative joint disease<br />
and osteoarthritis.<br />
Angiogenesis is a complex process, which<br />
involves the development of new vessels<br />
from existing ones. These new vessels<br />
grow in response to inflammation, injury,<br />
hypoxia and increased metabolic need. 30<br />
As the MCL of the ACL ruptured knee may<br />
experience all of these factors, angiogenesis<br />
may prove crucial to the viability of the<br />
tissue. Unfortunately, growth of new blood<br />
vessels in supporting connective tissues of<br />
an ACL ruptured joint may compromise its<br />
mechanical properties and lead to further<br />
tissue degradation and inflammation. These<br />
new angiogenic vessels are deficient in<br />
several ways compared with more mature<br />
vessels. Angiogenic vessels are considered<br />
chronically “leaky” and allow for greater<br />
tissue exudation and leukocyte diapedesis. 31<br />
Increased fluid exudation can increase the<br />
creep and decrease low-level stress – strain<br />
mechanics of the MCL. 32 This state is<br />
evident when qualitatively analyzing the<br />
images captured by the confocal microscope.<br />
In the ACL ruptured MCLs, the CD-31 and<br />
SMA labeling was denser in comparison to<br />
control MCLs. Further, increased leukocyte<br />
content may exacerbate the inflammatory<br />
conditions of the joint and prolong<br />
inflammation in the ACL ruptured knee. 30<br />
PPAR-γ agonists have been found to be<br />
involved in vascular biology, inflammatory<br />
responses, tissue repair, cell differentiation<br />
and proliferation. 12-15 In one study, a PPAR-γ<br />
agonist was found to be expressed in<br />
rheumatoid synovial, osteoarthritic, and<br />
normal cells. 16 In another, 15d-PGJ and 2<br />

interleukin-1β production.<br />
To look at the role of PPAR-γ agonists on<br />
the angiogenic response following ACL<br />
rupture and its effect on secondary joint<br />
stabilizing structures, rabbits were given a<br />
low dose of 5 mg/kg /day of rosiglitazone<br />
for four weeks then had their MCLs CD-31<br />
and SMA volumes measured. This dose was<br />
chosen to see if levels less than 30 mg/kg<br />
used in another in vivo osteoarthritic guinea<br />
pig model study would be an effective<br />
treatment. 21 No rabbit had any ACL injury<br />
prior to surgery or injections. Quantification<br />
of the vascularity in the MCLs showed<br />
a significant 3-fold increase in vascular<br />
volume as identified by the volumetric CD-<br />
31 antibody label in the ACL transected<br />
knees versus controls. When looking at<br />
the effects of the rosiglitazone treatment,<br />
the vascular volumes of the treated ACL<br />
transected MCL was reduced to near<br />
control MCL levels. Overall, rosiglitazone<br />
has the ability to limit excess vascular<br />
endothelium development in the MCL after<br />
ACL transection.<br />
Quantification of the SMA volumes in the<br />
MCLs by volumetric SMA antibody labelling<br />
was also performed. Rosiglitazone caused<br />
a reduction in SMA volume over untreated<br />
ACL ruptured knees. An unexpected finding<br />
in this study compared to other studies was<br />
the similarity between SMA volumes in ACL<br />
ruptured MCLs and non-operated control<br />
MCLs. Another unexpected finding was that<br />
the control MCLs had a much greater SMA<br />
volume than the rosiglitazone treated MCLs,<br />
while CD-31 volumes in these groups were<br />
similar. A possible reason for these findings<br />
could be that the rosiglitazone treatment<br />
may affect the production of MMP-13 and<br />
interleukin-1β differently. In one study, the<br />
PPAR-γ agonist pioglitazone was shown<br />
to decrease interleukin-1β and MMP-13. 33<br />
Interleukin-1β is an angiogenic initiator<br />
effecting endothelial cell production. MMP-<br />
13 is a factor released from endothelial<br />
cells, which plays a role in the degradation<br />
of fibrous collagens, facilitating vascular<br />
smooth muscle and adventitial cell<br />
migration and proliferation. If rosiglitazone<br />
affects MMP-13 more than interleukin-1β<br />
this will lead to decreased smooth muscle<br />
production. Decreased levels of smooth<br />
muscle may contribute to endothelial<br />
dysfunction and decreased responsiveness<br />
of MCL vasculature, which has been found<br />
in ACL ruptured osteoarthritis models. 34<br />
Future studies with increased subjects per<br />
group, varying dosages of rosiglitazone and<br />
measurement of markers for interleukin-1β<br />
and MMP-13 need to be conducted to gain<br />
a better understanding of the mechanisms<br />
that are occurring.<br />
This study has two inherent weaknesses,<br />
which can confound the results obtained.<br />
First, there are only two subjects per group,<br />
which is quite low compared to a number<br />
of other rabbit studies conducted. 10, 34 In<br />
those cases, there were usually minimums<br />
of 6 rabbits per group. The second limitation<br />
was the use of the contralateral MCL in the<br />
rosiglitazone treated rabbits. Due to the<br />
budgetary constraints of the study, the cost<br />
incurred to treat separate control rabbits<br />
with rosiglitazone and increased subjects per<br />
group would not have been feasible.<br />
Based on our results, it seems that the<br />
rosiglitazone treatment has a significant<br />
impact on decreasing angiogenic activity<br />
in the MCL of the ACL ruptured rabbit<br />
model. Due to the reduced angiogenic<br />
activity, the use of this PPAR-γ agonist could<br />
prove beneficial in reducing the negative<br />
effects angiogenesis has on the structural<br />
and physiological properties of the MCL<br />
in response to an ACL ruptured human<br />
knee. Rosiglitazone may prove beneficial in<br />
other secondary stabilizing structures and<br />
components in the knee. Further studies<br />
looking at the effects of rosiglitazone on<br />
these structures by using RT-PCR, cartilage<br />
and meniscal grading, blood flow imaging of<br />
the MCL and biomechanical testing of the<br />
MCL are thus warranted.<br />
Overall, quantification of the vasculature of<br />
the MCL of ACL ruptured and rosiglitazone<br />
treated knees by confocal microscopy has<br />
shown that rosiglitazone significantly<br />
decreased the angiogenic and physiological<br />
degeneration of the MCL. Vascular<br />
endothelium volumes returned to near<br />
control levels in rosiglitazone treated MCLs<br />
in ACL ruptured knees while vascular smooth<br />
muscle volume was lower in rosiglitazone<br />
treated versus non – treated MCLs.<br />

ABSTRACT<br />
Background: Delusional parasitosis (DP)<br />
is a monosymptomatic hypochondrial<br />
psychosis characterized by a false belief<br />
that one is infected with parasites.<br />
Traditionally, treatment revolved around<br />
typical antipsychotics, especially pimozide.<br />
Pimozide’s adverse effect profile and the<br />
advent of atypical antipsychotics have made<br />
the latter the treatment of choice. Given the<br />
paucity of randomized control trials and<br />
relatively recent introduction of atypicals,<br />
little is known about their efficacy in the<br />
treatment of DP.<br />
Objective: The purpose of this study is to<br />
review the evidence for the efficacy and use<br />
of both typical and atypical antipsychotics<br />
as treatment modalities for DP, with a<br />
specific emphasis on the newer atypical<br />
pharmacologics. As well, we aim to provide<br />
suggestions on how best to implement<br />
treatment in a dermatological setting.<br />
Methods: Medline and EMBASE were<br />
searched for available literature for both<br />

types of antipsychotics used in the treatment<br />
of DP. A systematic review was not<br />
completed to allow for discussion of clinical<br />
application of treatment.<br />
Results: Risperidone and olanzapine are<br />
currently the most commonly used atypical<br />
antipsychotics in DP treatment and are<br />
as efficacious as pimozide (full or partial<br />
remission rates of 68% and 90% respectively<br />
vs. pimozide average of 79%), and have<br />
fewer side effects. Other atypicals such as<br />
quetiapine, aripiprazole and paliperidone<br />
as well as risperidone long acting injections<br />
have demonstrated promising remission<br />
rates > 75% in a limited number of patients,<br />
but still require further studies to be<br />
considered first-line therapies.<br />
Conclusion: Limited clinical studies<br />
with small study populations implicate<br />
risperidone and olanzapine as first line<br />
treatments, but more randomized control<br />
trials are needed. We also review methods<br />
of how dermatologists may best initiate<br />
treatment with atypical antipsychotics.<br />

INTRODUCTION<br />
Delusional parasitosis is a<br />
monosymptomatic hypochondrial psychosis<br />
characterized by an unwavering false<br />
belief that one is infected with parasites. 1<br />
Thieberge first described this disorder in<br />
1894, and the name delusional parasitosis<br />
(DP) was introduced in 1946. 2 The<br />
prevalence of DP is not well established,<br />
but is considered rare. Overall, the femaleto-male<br />
ratio of affected individuals is<br />
approximately 2:1, with the mean age of<br />
diagnosis being slightly higher for females<br />
than males (mean age, 50 years to 40 years). 3<br />
The classification of DP is as either primary<br />
or secondary. Primary DP is characterized<br />
by a somatic delusion lasting for at least<br />
1 month, whereby patients do not meet<br />
criterion A for schizophrenia and there can<br />
be no underlying cause of the delusion. 4<br />
Secondary DP results from the use of a<br />
substance, organic causes, or other medical<br />
or psychiatric disorders with the most<br />
common causes being schizophrenia,<br />
diabetes, depression, cardiovascular<br />
events, and neurodegenerative disease. A<br />
comprehensive review of other secondary<br />
causes of DP is discussed by Huber et al.<br />
(2007). 5<br />
Given that DP is a somatic delusion, patients<br />
often initially present to dermatologists<br />
instead of psychiatrists with symptoms of<br />
pruritis, crawling sensations attributed to the<br />
presence of parasites under the skin leading<br />
to secondary excoriations, lichenification,<br />
prurigo nodularis and full thickness<br />
ulcers. 6, 7 Commonly, patients bring in<br />
samples of skin in small boxes as proof<br />
that the parasites exist; this stereotypical<br />
presentation is referred to as “the matchbox<br />
sign.” 8 Furthermore, patients may attempt<br />
to rid these “parasites” with anti-scabetic<br />
permethrin cream or even perform harmful<br />
skin cleansing rituals with disinfectants<br />
or pesticides. 9<br />
METHODS<br />
Treatment of DP requires the differentiation<br />
between the primary and secondary forms.<br />
Treatment of secondary DP relies on treating<br />
the underlying cause or cessation of the<br />
offending drug. 10 Treatment of primary DP<br />
has mostly revolved around typical and the<br />
newer atypical antipsychotics, which have<br />
differing mechanisms of action compared<br />
to typical antipsychotics. We conducted a<br />
literature search using combinations of the<br />
search terms: delusion*, parasitosis, typical,<br />
atypical, antipsychotics and treatment, in<br />
EMBASE and PubMed inclusive of studies<br />
published prior to May 1, 2010. For studies<br />
involving typical antipsychotics, only those<br />
with n≥20 (including placebo group) were<br />
reviewed, since these represent the most<br />
influential studies on which the basis of<br />
typical antipsychotic treatment is formed.<br />
Due to the relatively recent introduction<br />
of atypical antipsychotics in the treatment<br />
of DP, the n values for these studies were<br />
significantly smaller; thus sample size was<br />
not used as a definitive exclusion criterion.<br />
We included at least one study for each<br />
atypical. The criteria we considered included<br />
the size of the study, with preference being<br />
given to larger sample sizes; whether or<br />
not numerous atypicals were compared<br />
within the same study, to control for variable<br />
treatment practices; and how well the<br />
study represented the general treatment<br />
population with respect to disease severity,<br />
co-morbidities and age.<br />
RESULTS<br />
Typical antipsychotics<br />
The most common typical antipsychotic<br />
used in the treatment of DP is pimozide. 11<br />
Pimozide is an approved treatment for<br />
Gilles de la Tourette syndrome in the United<br />
States, but it has also been shown to have<br />
a therapeutic effect for numerous offlabel<br />
disorders, such as DP. 10-19 Pimozide’s<br />
primary mechanism of action is via central<br />
Dopamine-receptor D2 antagonism. 12 One<br />
advantage of pimozide over other typical<br />
antipsychotics is its weak noradrenergic<br />
receptor blockade effect which reduces<br />
adverse side effects such as orthostatic<br />
hypotension and dizziness. 14<br />
A number of case reports, case series, and<br />
double-blind crossover trials showing<br />
the effects of pimozide in DP have been<br />
conducted (summarized in Table 1) 15-19 .<br />
The first double-blind crossover study was<br />
performed by Hamann and Avnstorp (1982)<br />
which demonstrated that 10 out of 11 DP<br />
patients had a decrease in Brief Psychiatric<br />
Rating Scale points and improvement of<br />
delusion and itching following 6 weeks<br />
of treatment with pimozide, while only<br />
one patient from the placebo group<br />
experienced improvement in the 4 week<br />
evaluation period. 15 In 1986, another<br />
double-blind crossover study showed<br />
significant improvement in 10 DP patients<br />
administered 2-8 mg/day of pimozide for<br />
3 weeks followed by a relapse following 2<br />
weeks of placebo treatment and subsequent<br />
improvement when pimozide was restarted.<br />
Improvement was based on the authors’<br />
own rating scale using symptoms of DP. 13<br />
Although these studies used a placebo<br />
control, the results are limited by the<br />
small sample size (i.e. n=11 and n=10<br />
13, 15<br />
respectively).<br />
The rates of partial and full remission are<br />
variable amongst studies with pimozide.<br />
Zomer et al. (1998) found a partial to full<br />
remission rate of 61% (11 out of 18 patients)<br />
in patients treated with pimozide compared<br />
to 20% (3 out of 15) in the non-treatment<br />
group. 16 A survey conducted by Lyell (1983)<br />
demonstrated 44 of 66 patients treated<br />
with pimozide demonstrated full or partial<br />
remission (combined remission rate of<br />
67%). 17 Partial and full remission of DP in<br />
patients treated with pimozide have been<br />
reported as high as 87% (n = 46)18 to 100%<br />
(n=10). 13<br />
The long-term efficacy of treatment with<br />
pimozide was demonstrated in a follow-up<br />
study by Lindskov and Baadsgaard (1985). 19<br />
Fourteen patients were followed up between<br />
19 and 48 months after termination of<br />
pimozide treatment. Seven patients had<br />
improved, while 4 had deterioration of<br />
their symptoms and 3 had relapses that<br />
responded well to intermittent pimozide<br />
treatment.<br />
A systematic review conducted by Lepping<br />
et al. (2007) found a total of 92 patients<br />
treated with typical antipsychotics for<br />
primary DP. Of those 92, 40 (43%)<br />
had partial remission, 45 (49%) had<br />
full remission and 7 (8%) showed no<br />
improvement or were lost to follow-up. 10 Of<br />
the 53 patients treated with pimozide, 50<br />
had either full or partial remission (94%),<br />

atypical antipsychotics<br />
Atypical antipsychotics differ from typical<br />
antipsychotics in their various mechanisms<br />
of action and are generally associated with<br />
less extrapyramidal symptoms. Meltzer et<br />
al. (1989) 20 proposed that a preference for<br />
5-HT2A receptor antagonism rather than<br />
DA D2 receptor antagonism distinguishes<br />
this class of drugs, although a number of<br />
other hypotheses question this. 21, 22 Atypical<br />
antipsychotics used in the treatment of<br />
DP that will be discussed are risperidone,<br />
olanzapine, quetiapine, aripiprazole, and<br />
paliperidone (Table 2).<br />
A number of case series have utilized<br />
risperidone as the main treatment modality<br />
for DP. Gallucci and Beard23 first established<br />
risperidone as a potential treatment of DP.<br />
Overall, of the 41 cases of DP treated with<br />
risperidone that we reviewed, 28 had a full<br />
or partial remission, one had no change in<br />
symptoms and 12 were lost to follow up or<br />
were switched to another drug during the<br />
treatment course – reasons for switching<br />
medications include co-morbidities that<br />
could be simultaneously treated with<br />
DP using another drug and unspecified<br />
intolerance of risperidone (Table 2). 24-28<br />
The most recent and largest retrospective<br />
case study followed 20 patients utilizing<br />
atypical antipsychotics for DP. 26 Fifteen<br />
patients were treated with risperidone as<br />
the main atypical antipsychotic and 10 of<br />
them had full or partial remission, while 5<br />
were lost to follow-up. Five patients were<br />
treated with olanzapine as the main atypical<br />
University of <strong>Alberta</strong> Health Sciences Journal • April 2012 • Volume 7 • Issue 1
antipsychotic. Of these patients, 4 had full or<br />
partial remission, and 1 was lost to follow up.<br />
Another case series compared 4 patients<br />
treated with risperidone and one<br />
treated with quetiapine. 27 Three of the 4<br />
risperidone-treated patients experienced<br />
total resolution of delusions; one of these<br />
three patients was also on lithium, another<br />
was on sertraline and alprazolam as well,<br />
and another was also on sertraline and<br />
donepezil. The last risperidone treated<br />
patient had a decrease in delusions and was<br />
on no other medications. The patient treated<br />
with quetiapine showed partial remission<br />
and was also on venlafaxine, clonazepam,<br />
buspirone and bupropion.<br />
Shah and Pervez (2009) published only<br />
the second case report for the use of<br />
risperidone long-acting injections (RLAI). 29<br />
The patient refused to take oral risperidone,<br />
but accepted RLAI 25 mg IM every 2 weeks.<br />
This dosage was titrated up to 37.5 mg IM<br />
on discharge and she then switched to 5<br />
mg/day PO risperidone. Her symptoms<br />
improved, although complete remission was<br />
not achieved.<br />
There are also newer atypical antipsychotics<br />
whose efficacy in the treatment of DP<br />
has only been documented in a limited<br />
number of case studies. One example is<br />
aripiprazole. 30-32 Rocha and Hara (2007)<br />
documented the first case of aripiprazole<br />
treatment in an 85 year old DP patient<br />
and she underwent full remission. 30 In<br />
a subsequent study, 2 patients with DP<br />
were treated with aripiprazole and both<br />
had complete remission. 31 Paliperidone, an<br />
atypical antipsychotic approved by the FDA<br />
in 2006, has only been used in one DP case,<br />
where an 88 year old man treated with the<br />
drug underwent complete remission. 33<br />
DISCUSSION<br />
Our review of typical antipsychotics<br />
indicates that pimozide is an effective<br />
treatment option for DP. The rates of full<br />
or partial remission were similar to the<br />
numbers reported in a systematic review by<br />
Lepping et al. (2007). 10 There have been a<br />
number of smaller case reports and studies<br />
utilizing other typical antipsychotics such as<br />
haloperidol, trifluoperazine, flupenthixol and<br />
fluphenazine depot, all of which showed<br />
excellent rates of full or partial remission. 10<br />
Despite the past successes of pimozide, it is<br />
no longer considered first-line treatment of<br />
DP, due to the advent of the safer atypical<br />
antipsychotics. 34<br />
Furthermore, the long-term use of pimozide<br />
is associated with a number of adverse<br />
side effects. Extrapyramidal symptoms<br />
such as tardive dyskinesia, parkinsonism<br />
and akathisia occur in less than 10-15%<br />
of patients treated with pimozide for<br />
schizophrenia, and Gilles de la Tourette<br />
Syndrome. 11 It has also been associated<br />
with clinically significant QT interval<br />
c<br />
prolongation, including Torsades de Pointes,<br />
possibly due to the calcium channel<br />
blocking effects of the drug. 7, 14, 35 These side<br />
effects, especially its cardiac effects and<br />
drug interactions (drugs metabolized by<br />
cytochrome P450 isoenzyme 3A4), make<br />
pimozide a non-ideal DP therapy. 34<br />
Much less is known about atypical<br />
antipsychotics, because of their relatively<br />
recent introduction compared to typical<br />
antipsychotics. The largest review to date<br />
of atypical antipsychotic use in DP was<br />
conducted in 2008 by Freudenmann and<br />
Lepping, 34 which concluded that atypical<br />
antipsychotics should be the first line<br />
therapy for DP.<br />
The atypical antipsychotics with the largest<br />
sample sizes in our review were risperidone<br />
and olanzapine. Risperidone has been<br />
established as the most common atypical<br />
antipsychotic used in the treatment of DP.<br />
The particular effectiveness of this drug has<br />
been linked to its high affinity for 5-HT2 receptors, a receptor which has been linked<br />
to psychotic processes and perceptual<br />
differences. 12 Although risperidone’s<br />
side effect profile is superior to that of<br />
typical antipsychotics, there are instances<br />
where parkinsonism and akathisia have<br />
been produced by its use and it has been<br />
associated with a mild increase in metabolic<br />
syndrome. 32 An added benefit of risperidone<br />
is that it is the only atypical antipsychotic<br />
available as a long-acting depot. Long acting<br />
injections are particularly useful in patients<br />
who are demonstrating harmful behaviours<br />
and refusing to comply with oral treatment.<br />
The goal of such a treatment would be<br />
to help the patient accept their problem<br />
is psychological and thus comply with<br />
oral therapy.<br />
Olanzapine is the second most common<br />
atypical antipsychotic used in DP<br />
treatment. 34 Its side effect profile is also<br />
superior to that of pimozide and it rarely<br />
causes extrapyramidal syndrome. However,<br />
this medication is closely associated with<br />
metabolic syndrome and sedation. 32 Its use<br />
is still limited by a smaller body of evidence,<br />
but the fact that three patients treated with<br />
risperidone were switched to olanzapine<br />
due to intolerance suggests it may be a more<br />
tolerable drug. 25<br />
Quetiapine had an excellent remission rate,<br />
but with a small sample size (n=2), more<br />
studies must be done in order to assess its<br />
use in the treatment of DP. Freudenmann<br />
and Lepping (2008) found a full or partial<br />
remission rate of 88% after reviewing 8<br />
cases. 34 The side effect profile of quetiapine<br />
is generally limited to drowsiness, dizziness<br />
and postural hypotension, with minimal<br />
risk of extrapyramidal symptoms or adverse<br />
cardiac effects. 36 Quetiapine’s excellent<br />
side effect profile combined with its high<br />
remission rate makes it a potential treatment<br />
for DP.<br />
The results of aripiprazole treatment in DP<br />
have only been published for 4 patients to<br />
date with all 4 demonstrating full or partial<br />
remission. 23-25 There have not been any<br />
randomized control trials or placebo cross<br />
over studies performed with aripiprazole<br />
and DP, but the case study results are<br />
promising. Adverse effects of aripiprazole<br />
include nausea and akathisia, but it is nonsedating<br />
and less often associated with<br />
extrapyramidal symptoms and metabolic<br />
disturbances. 37 This excellent side effect<br />
profile may make it beneficial to DP patients<br />
who cannot tolerate the side effects of<br />
other antipsychotics.<br />
Paliperidone is the latest atypical<br />
antipsychotic used in the treatment of DP.<br />
Paliperidone is the main active metabolite<br />
of risperidone and it blocks 5-HT and D -<br />
2A 2<br />
receptors. It has a long half-life of 24 hours,<br />
which decreases the number of daily doses.<br />
As well, it decreases the risk of any potential<br />
adverse drug reactions, which is especially<br />
important because many DP patients have<br />
numerous co-morbidities being treated<br />
simultaneously. 33 The clinical efficacy of<br />
paliperidone as a treatment for DP needs<br />
to be confirmed by further case studies or<br />
randomized control trials.<br />
CLINICAL IMPLICATIONS<br />
Diagnosis of DP is definitely within the<br />
scope of a dermatology practice. However,<br />
the psychological basis of the disorder<br />
makes initiating therapy in a dermatologist<br />
office challenging. Patients often feel as<br />
if their symptoms are not being seriously<br />
considered when the dermatologist tries<br />
to explain that the disease is psychotic in<br />
nature. Referral to a psychiatrist is often<br />
met with anger and frustration, resulting<br />
in the patient either seeking the opinion<br />
of another dermatologist or resorting to<br />
self-treatment, which may be potentially<br />
harmful. 10 It may be prudent to ask the<br />
patient’s thoughts on you consulting an<br />
expert colleague who deals with similar<br />
conditions more frequently. This will open<br />
the door to discussing the management<br />
plan with a psychiatrist, while empowering<br />
the patient to be actively involved in the<br />
treatment decision.<br />

REVIEW
REVIEW<br />
In the event a patient demands a skin<br />
biopsy, it may be worthwhile to do one<br />
rather than risk losing rapport with the<br />
patient. Koo and Lee (2001) suggest making<br />
a verbal agreement beforehand, and that<br />
the patient be more flexible in his or her<br />
thinking if the biopsy returns negative; this<br />
may make it easier to convince the patient<br />
to take antipsychotic medications after<br />
the biopsy. 8 When antipsychotic therapy<br />
is initiated, it is advisable to offer the<br />
medication as an empirical therapy while<br />
emphasizing the potential for reduction<br />
in symptoms, like biting and crawling<br />
sensations. 8 Potential side effects of the<br />
antipsychotics should be discussed with<br />
the patient beforehand, to enhance patient<br />
compliance. Considering the patient’s comorbidities<br />
when selecting the particular<br />
antipsychotic to be used can help tailor<br />
the choice; for example, in a patient with<br />
diabetes, olanzapine should be avoided<br />
due to its potential for metabolic syndrome<br />
side effects. Depot injections (risperidone)<br />
should only be pursued as an option<br />
if the patient is willing to be regularly<br />
monitored by a psychiatric team. Working<br />
in conjunction with the patient’s family<br />
physician to monitor both the side effects of<br />
the antipsychotic medication and course of<br />
the DP will reduce the risks of complications<br />
from the therapy, especially if the patient<br />
refuses the involvement of psychiatry.<br />
CONCLUSION<br />
There has never been a randomized<br />
control trial directly comparing atypical<br />
antipsychotics to typical antipsychotics,<br />
which would be useful in establishing a<br />
clear treatment of choice for DP. 10 However,<br />
based on the efficacy of drugs in both<br />
classes as shown in Tables 1 and 2, it would<br />
appear that atypical antipsychotics have a<br />
lower side effect profile while achieving a<br />
partial to full remission rate similar to typical<br />
antipsychotics. The reduction in adverse<br />
iatrogenic events would improve patient<br />
compliance to treatment and help construct<br />
a therapeutic relationship between the<br />
patient and physician.<br />

Abstract<br />
Cardiac disease is the leading cause of death<br />
for both men and women in developed<br />
countries. In Canada, the incidence of<br />
diabetes and hypertension has recently<br />
increased by 90% in middle income groups,<br />
resulting in substantially more cardiac<br />
disease. How can medical professionals<br />
keep up with these statistics? Imagine if<br />
physicians could regenerate the wounded<br />
heart post-myocardial infarction, or even<br />
bioengineer an entirely new organ. This<br />
is the future of cardiovascular medicine.<br />
Regenerating myocardium is hardly an easy<br />
undertaking; the heart contains about 20<br />
million cardiomyocytes per gram of tissue,<br />
meaning – in the left ventricle alone – there<br />
are approximately 4 billion cardiomyocytes<br />
at risk during a heart attack. Many cells are<br />
required to replace damaged tissue, making<br />
complete regeneration challenging. In light<br />
of the rich therapeutic potential seen in<br />
both adult and embryonic stem cells, it is no<br />
surprise that biomedical research on these<br />
cells has seen an intense amount of activity<br />
in the past decade. From fetal-derived<br />
cardiomyocytes and skeletal myoblasts, to<br />
bone marrow stromal cells and peripheral<br />
blood CD34 + cells, a myriad of cell lines<br />
have been tested to date. The last decade<br />
has seen an explosion of novel approaches<br />
using these cells to restore cardiac function<br />
post-infarction: from developing cell-based<br />
pacemakers and cardiac grafts, to building<br />
bioartifical hearts. This review will paint a<br />
picture of the rapidly changing landscape<br />
of cardiovascular medicine by elaborating<br />
on these new technologies. Limitations<br />
of these approaches will be discussed, as<br />
well as future developments. In the field of<br />
cell-based cardiac repair, the possibilities<br />
seem endless.<br />
Preamble<br />
Cardiac disease is the leading cause<br />
of death for both men and women in<br />
developed countries. In fact, cardiovascular<br />
disease – including coronary heart disease,<br />
hypertension, stroke, and congestive heart<br />
failure – has ranked as the number one<br />
cause of death in the US every year since<br />
1900, except during the 1918 influenza<br />
epidemic. 1 In 2007, heart disease accounted<br />
for 26% of all deaths in the US, resulting<br />
in an age-adjusted death rate of 211 per<br />
100,000 people. 2 Also shocking is the cost<br />
of medication, health care services, and lost<br />
productivity due to heart disease in the US:<br />
a projected $508 billion in 2010. 3 This cost<br />
is not expected to decrease any time soon.<br />
In Canada, the incidence of risk factors for<br />
cardiac disease has increased substantially<br />
over the past decade: both diabetes and<br />
hypertension have increased by 90% in<br />
middle income groups (roughly 50% of<br />
the population), 4 resulting in substantially<br />
more cardiovascular disease. What if there<br />
existed a therapeutic technique to treat that<br />
which physicians have for so long deemed<br />
incurable? What if one could regenerate the<br />
wounded heart after a myocardial infarction<br />
using stem cells? Imagine if one could<br />
bioengineer a new heart. This could be the<br />
future of cardiovascular medicine.<br />
Over the last decade, the utilization of<br />
stem cells to repair the damaged heart has<br />
seen an explosion of advancements. Novel<br />
therapeutic techniques will be addressed in<br />
detail: the methods used and the resulting<br />
applications of these innovations will be<br />
described. Limitations of these techniques<br />
and future developments will also be<br />
reviewed.<br />

Introduction to Cardiac Repair<br />
Cell therapy has experienced much<br />
growth over the last 25-30 years: from<br />
its first applications for reconstituting<br />
the immune system after a bone marrow<br />
transplant, to treating diabetes with<br />
pancreatic islet transplantation. 5 More recent<br />
treatments include those for liver cirrhosis,<br />
Huntington’s disease, and Parkinson’s<br />
disease. 6 As for heart disease, the majority<br />
of therapies have been centered on the<br />
treatment of heart damage post-myocardial<br />
infarction (MI). How can myocardial repair<br />
occur in an organ that is thought to be<br />
incapable of naturally self-repairing itself?<br />
The heart does not experience regeneration<br />
as the liver does; following MI, scar tissue<br />
forms over the infarcted area. Therefore,<br />
much of the research has been geared<br />
towards using cell-based approaches to<br />
regenerate myocardium directly from<br />
donor stem cells. Regenerating heart<br />
muscle following an MI is hardly an easy<br />
undertaking; the myocardium contains<br />
about 20 million cardiomyocytes per gram of<br />
tissue, so there are approximately 4 billion<br />
cardiomyocytes at risk in the left ventricle<br />
alone during a heart attack. Assuming<br />
that any repair therapy restores at least<br />
1/2 to 2/3 of the damaged myocardium,<br />
true regeneration would require 500 to 800<br />
million cells. 7 In light of the therapeutic<br />
potential seen in both adult and embryonic<br />
stem cells (coined ES cells by Martin in<br />
1981), 8 it is no surprise that biomedical<br />
research on these cells has seen an intense<br />
amount of activity in the past decade.<br />
Stem Cell Sources<br />
Stem cells not only have an unlimited<br />
capacity to self-renew, but they are also<br />
pluripotent; this means that stem cells<br />
can be induced to differentiate into cells<br />

with specific functions. 9 Primarily two<br />
types of mammalian stem cells are used in<br />
myocardial regeneration: embryonic stem<br />
cells found in the blastocyst during early<br />
embryogenesis, and adult stem cells found<br />
in adult tissues acting as progenitor cells.<br />
ES cells are pluripotent and can potentially<br />
give rise to a number of cell types, they<br />
are vital to tissue regeneration therapy,<br />
regardless of the field of research. Skeletal<br />
myoblasts, on the other hand, are committed<br />
progenitor cells of skeletal muscle; they<br />
are resistant to ischemia and highly<br />
proliferative. 10 These myoblasts, harvested<br />
from neonatal and adult animals, have<br />
been shown to differentiate into skeletal<br />
myotubes and improve left ventricular<br />
function following an infarct. 10 These<br />
results have been obtained in autologous,<br />
syngeneic, allogenic, and xenogenic<br />
transplants – largely in mice and rats, but<br />
also in swine and canine subjects. 10<br />
Adult bone marrow derived stem cells have<br />
also been studied: there are hematopoietic<br />
stem cells, endothelial progenitor cells,<br />
and mesenchymal stem cells in adult bone<br />
marrow. Research has shown that treatment<br />
with mesenchymal stem cells (MSCs –<br />
precursors to muscle, bone, tendons, and<br />
ligaments) improves myocardial function<br />
by limiting ventricular remodeling. 11 It<br />
was known that intramyocardial injection<br />
of Akt-MSCs (mesenchymal stem cells<br />
overexpressing the survival gene Akt)<br />
restored cardiac function after only 72<br />
hours. 11 Gnecchi et al. hypothesized that,<br />
because such a rapid recovery could not<br />
be due to differentiation of the donor cells,<br />
regeneration was accomplished through the<br />
action of factors provided by the MSCs. 12<br />
It was thought that these factors acted in<br />
a paracrine fashion to rescue the damaged<br />
heart tissue. Gnecchi et al. found that it<br />
is possible, in an animal model, to use<br />
mesenchymal stem cells to alleviate acute<br />
MI by injecting a cell-free supernatant<br />
that had been recovered from cultures of<br />
mesenchymal stem cells. 12<br />
Adult CD34 + cells, easily obtained from<br />
peripheral blood, can trans-differentiate<br />
into cardiomyocytes in vivo at the site of<br />
injury in mice – yet this is still a work in<br />
progress. 13 Lastly, some sources suggest that<br />
there are small populations of “resident<br />
cardiac stem cells” endogenous to the heart<br />
that may serve a minor role in repair. 14<br />
While researchers clearly have many types<br />
of stem cells at their disposal for use in<br />
cardiovascular therapies, only ES-derived<br />
cardiomyocytes and skeletal myoblasts<br />
have been able to achieve a proper level<br />
of cell survival for complete myocardial<br />
regeneration. 7<br />
14<br />
Skeletal Myoblast<br />
Transplantation<br />
Studies on skeletal myoblasts began with<br />
work of Chiu et al., dating back to 1995.<br />
His team studied the ability to repair<br />
injured myocardium in the presence of<br />
skeletal muscle cells, called “satellite<br />
cells.” 15 Each skeletal muscle fiber contains<br />
a few myogenic satellite cells, which are<br />
normally undifferentiated and quiescent.<br />
Injury activates these cells, causing them to<br />
enter mitosis and restore the functionality<br />
of the fiber. 16 Chiu et al. hypothesized that<br />
satellite cells, when implanted into injured<br />
myocardium and influenced by the cardiac<br />
environment, would undergo “milieudependent<br />
differentiation.” 15 Chiu et al.<br />
conducted two experiments: one in which<br />
the histological outcome of implanting<br />
skeletal satellite cells into acutely damaged<br />
myocardium was observed, and the other<br />
in which the presence of satellite cells at<br />
the site of implantation was confirmed. 15<br />
Satellite cells were isolated from samples<br />
obtained from the tibialis anterior muscle of<br />
adult dogs, and then labeled with tritiated<br />
thymidine. Following which, the cells<br />
were grown in vitro for either 10 days or 3<br />
weeks and implanted into the cryoinjured<br />
myocardium of the same animal. A catheter<br />
was used to implant the cells into the<br />
injured left ventricular free wall, which was<br />
acutely damaged by liquid nitrogen. Implant<br />
sites were evaluated radiographically to<br />
Figure 1. Data comparing<br />

showed successful transdifferentiation of<br />
myoblast satellite cells into cardiomyocytes:<br />
new muscle cells in the implant sites<br />
histologically mimicked cardiac muscle,<br />
including the presence of intercalated<br />
discs, which are unique to cardiac muscle<br />
fibers. 15 Chiu et al. concluded that the<br />
cardiac environment played a role in cell<br />
differentiation, possibly through growth<br />
factors or other signaling pathways.<br />
In 1998, Taylor’s group made use of the<br />
cryoinfarction and cell implantation<br />
techniques described by Chiu et al. to test<br />
whether skeletal myoblast transplantation<br />
actually improves myocardial performance. 17<br />
One week following myocardial injury,<br />
skeletal myoblasts from the rabbit hindlimb<br />
soleus muscle were transplanted into<br />
the damaged heart of the same rabbit.<br />
Following transplantation, 7 of the 12<br />
rabbits had an improvement in myocardial<br />
performance: PRSW slope (an indication of<br />
systolic function and contractility) increased<br />
34–400% compared to post-infarct values<br />
(Figure 1). 17 Electron microscopy of the<br />
implant sites did not show multinucleated<br />
skeletal fibers, but rather cells that<br />
resembled cardiomyocytes (Figure 2). 17<br />
For the first time in animals, myoblast<br />
transplantation into acutely injured<br />
hearts was reported to improve cardiac<br />
performance in vivo.<br />
University of <strong>Alberta</strong> Health Sciences Journal • April 2012 • Volume 7 • Issue 1
Embryonic Stem Cell<br />
Transplantation<br />
Human ES cells served as another jumpingoff<br />
point for producing differentiated<br />
cardiomyocytes. Could ES cells normalize<br />
cardiac performance by being transplanted<br />
into injured myocardium? In 2002, Min’s<br />
team set out to answer this question using<br />
rat models. ES cells were transfected with<br />
green fluorescent protein (GFP) to identify<br />
cell survival, and transplanted into male<br />
rats after inducing MI by ligating the left<br />
anterior descending coronary artery. 18<br />
Hemodynamics and muscle contraction<br />
were evaluated both post-MI and after the<br />
transplantation. Survival of the transplant<br />
cells was confirmed by observing GFP<br />
expression. Cardiac α-myosin heavy chain<br />
and (α-MHC) and troponin I (cTnI) were<br />
identified using specific antibodies. Not<br />
only did these cells survive, but they also<br />
improved cardiac function. Cardiac muscle<br />
wall tension was measured to determine<br />
myocyte function at a given ventricular<br />
pressure and radius (according to LaPlace’s<br />
Law, wall tension (T) is proportional<br />
to intraventricular pressure (P) and<br />
ventricular radius (r): T ∝ P ∙ r). Wall tension<br />
increased ~2-fold in the rats that had<br />
undergone transplants. 18<br />
Cell-Based Pacemakers<br />
Thus far, efforts in stem cell transplantation<br />
have been discussed with the goal of<br />
repairing infarcted cardiac tissue. In 2004,<br />
Xue et al. approached cardiac therapy<br />
from a new angle: would it be possible to<br />
coordinate inactive cardiac muscle cells<br />
to beat synchronously with pacemakerlike<br />
donor cells? Human ES cells were<br />
transfected with GFP and transplanted<br />
subepicardially into guinea pigs in vivo. 19<br />
After allowing the stem cells differentiate,<br />
a beating outgrowth of cardiomyocytes was<br />
dissected and checked for GFP expression.<br />
The cells were then transplanted onto a<br />
layer of quiescent rat cardiomyocytes in<br />
vitro, resulting in synchronous contractions<br />
at ~49 bpm of GFP-expressing cells and rat<br />
cardiomyocytes. 19 Without direct contact<br />
between the two cell lines, there was no<br />
synchronous beating. It is important to<br />
note that, unlike cell-based pacemakers,<br />
electronic pacemakers are largely unable<br />
to adapt to fluctuating requirements. In<br />
addition, sensing and pacing leads may<br />
become dislodged or malpositioned, and the<br />
pocket in which the electronic pacemaker<br />
sits is prone to infection. 20 This research<br />
shows that bio-pacemakers are clinically<br />
attractive, and may overcome the limitations<br />
of the electronic pacemaker.<br />

Bioengineered Cardiac Grafts<br />
Because it is generally accepted that the<br />
myocardium cannot regenerate after injury,<br />
much research has gone into replacing<br />
damaged muscle. 21 For example, Leor et al.<br />
tested whether bioengineering cardiac tissue<br />
within three-dimensional (3D) scaffolds<br />
would enhance cardiac function after<br />
extensive MI. 21 This novel practice involves<br />
the use of 3D cross-linked biopolymer,<br />
which serves as a support structure upon<br />
which functional cells can grow. The<br />
structure biodegrades once the cells have<br />
formed their own matrix. Rat cardiac cells<br />
were isolated and cultured, and seeded in<br />
cylindrical scaffolds made of sodium alginate<br />
with 100 μm pores. 21 Biograft implantation<br />
was performed 7 days post-MI: in each<br />
rat, two scaffolds were attached to the scar<br />
tissue induced by left main coronary artery<br />
blockage. After 9 weeks, the rats were<br />
euthanized, and the hearts were examined.<br />
Under histology, the scaffolds showed that<br />
they had successfully merged with the<br />
infarcted area (Figure 3). 21 Control rats were<br />
subjected to heart failure as a result of left<br />
ventricular remodeling post-MI – but in the<br />
biografted rats, there was less ventricular<br />
remodeling and deterioration.<br />
Biotechnology Builds a Heart<br />
Over 1,000 Canadians are waiting for a<br />
donor heart. 22 Bioartificial hearts could<br />
potentially circumvent this issue, and<br />
prevent significant sequelae associated with<br />
allogeneic heart transplantation – including<br />
long-term immunosuppression, renal failure,<br />
and hypertension. 23 Ott et al. describes an<br />
attempt to fabricate the construct of an<br />
entire heart, complete with vasculature<br />
and inner architecture: it involves<br />
“decellularizing” whole adult rat hearts<br />
using detergents, and then repopulating<br />
them with neonatal cardiac cells (Figure 4). 23<br />
This ingenious technique utilizes “nature’s<br />
platform” of the heart, rather than<br />
attempting to engineer it from scratch. Not<br />
only does this bioartifical heart mimic the<br />
structure and cellular layout of a true heart –<br />
it also functions like one. When stimulating<br />
the constructs, acceptable measurements<br />
of cardiac function were obtained in 5 out<br />
of 8 hearts. 23 It is hypothesized that the<br />
bioengineered heart could be used as a full<br />
replacement organ in end-stage failure.<br />
However, this will only be possible with<br />
further organ maturation, reseeding of the<br />
heart’s vasculature with endothelial cells,<br />
and scaling up of the technology to work<br />
with human-sized hearts.<br />
Limitations<br />
Given the scarcity of donor hearts available<br />
to meet transplant needs, these approaches<br />
have immense advantages over heart<br />
transplants. However, a number of hurdles<br />
must be overcome before human ES cells<br />
can be used clinically. For instance, ethical<br />
issues related to accessing embryos limit<br />
scientists’ investigations. Also, human ES<br />
cells must go through rigorous testing<br />
before the cells can be used as a regenerative<br />
therapy. If transplanted regenerative cells are<br />
contaminated with undifferentiated ES cells,<br />
a tumor could form. 24 It has been suggested<br />
that differentiation of ES cells prior to<br />
implantation may prevent the formation<br />
of cancerous teratomas. 25 Also, in most cell<br />
transplant studies, many cells are lost before<br />
blood and nutrient supplies are established. 7<br />
Introducing exogenous genes into transplant<br />
cells could make them more robust or allow<br />
them to release growth factors. For example,<br />
induced pluripotent stem cells have been<br />
studied by obtaining fibroblasts after genetic<br />
reprogramming; however, these have been<br />
shown to form teratomas as well. 26<br />
It should also be noted that, in certain<br />
animal models, stem cells end up travelling<br />
from the heart to other nearby organs only<br />
a few hours post-transplant, and in some<br />
cases, the use of skeletal myoblasts has<br />
caused ventricular tachycardia. 27 Cell-based<br />
pacemakers could also lead to arrhythmias<br />
if the graft undergoes changes in ion<br />
channel expression. 19 Innovative methods<br />
have been studied in an attempt to prevent<br />
arrhythmias. A recent clinical, the CAuSMIC<br />
study, used a novel minimally-invasive<br />
catheter system to deliver autologous<br />
myoblasts to 23 human subjects with NYHA<br />
class II to IV heart failure. 28 This technique<br />
resulted in significantly improved heart<br />

failure symptoms, with no difference in the<br />
incidence of arrhythmias between treatment<br />
and control. 28 Still, more extensive clinical<br />
trials are required to overcome the many<br />
limitations of stem cell therapy.<br />
Future developments<br />
Transplant cell engineering, cell<br />
differentiation prior to implantation, and<br />
minimally-invasive methods may help<br />
improve the next generation of techniques.<br />
The possibilities seem endless in the field<br />
of cell-based cardiac repair. Judging by the<br />
current explosion of research, it may be<br />
possible to transplant tissue engineered<br />
16<br />
valves in the near future. For instance,<br />
trileaflet heart valves – fabricated from<br />
scaffolds and seeded with autologous<br />
stem cells – have been implanted in sheep<br />
using a minimally-invasive technique,<br />
resulting in functional valves. 29 Yet, why stop<br />
there? Complete organogenesis is within<br />
sight. “Organ printing”, the assembly of<br />
3D vascularized soft organs, is a feasible<br />
technology. With the help of computerized<br />
technology, sheets of single cells can be<br />
placed one on top of another using a cell<br />
printer, almost like printing paper. 30<br />
Stem cells hold the key to rebuilding<br />
damaged tissues. One decade ago, this was a<br />
radical idea; now it is a popular experimental<br />
concept with early clinical trials being<br />
conducted around the world. Research<br />
into this area offers promise to a variety of<br />
medical fields. However, rigorous testing<br />
is still required before moving from bench<br />
to bedside.<br />

Fine art in health sciences: Recognizing<br />
students who find time to make art<br />

Making time for art is not always easy,<br />
especially for medical and dental students.<br />
Keeping up with lectures, readings,<br />
assignments and clinical skills leaves little<br />
room for photography, painting, sketching<br />
and other artistic projects. 1 The arts can be<br />
easily pushed to the backburner, forgotten,<br />
or crowded out by the demands of these<br />
intensive programs. For Katie Stringer,<br />
a second year medical student at the<br />
University of <strong>Alberta</strong>, keeping photography<br />
a part of her life has become increasingly<br />
difficult: “In some ways it makes me sad<br />
to talk about my art these days. While it<br />
has brought me a lot of joy over the years,<br />
I now find myself wishing I had more time<br />
to explore my craft.” 2 This sentiment is not<br />
unique. As students in health sciences, we<br />
can safely expect an emphasis on science<br />
and medicine in our studies. However, it’s<br />
not only Katie who recognizes the added<br />
value of engaging in art. As demonstrated<br />
by twenty five undergraduate medical<br />
and dental students, artistic expression<br />
through visual arts can play a powerful and<br />
multifaceted role in processing, enjoying and<br />
improving our educational experience.<br />

so very long ago, considered to be very<br />

generally accepted division between art<br />
and science was challenged by the students<br />

launch of the University of <strong>Alberta</strong> Medical<br />
& Dental Student Art Show. The idea for the<br />
event was sparked when medical student<br />

Asha Olmstead noticed the artistic talent<br />
of a few of her classmates and suggested<br />
a class art show. As plans progressed,<br />
it became clear that there was interest<br />
throughout the faculty, and the show was<br />
expanded to include students from all four<br />
years. The event allowed any medical or<br />
dentistry student to showcase their artwork<br />
for classmates, colleagues, instructors and<br />
friends, while also supporting a local nonprofit<br />
organization. “I thought the opening<br />
night event was a great opportunity to<br />
model the different ways of giving to a<br />
community,” says Roxanne Felix, a research<br />
consultant and assistant adjunct professor<br />
at the University of <strong>Alberta</strong> School of<br />
Public Health. 4<br />
I was really impressed with the<br />
energy and commitment brought<br />
by the students and faculty to<br />
this event. I think the University<br />
needs to foster these kinds of<br />
cross-sector and innovative events.<br />
There is obviously a lot of interest<br />
and passion for looking at how<br />
health sciences and the arts interact<br />
– now we just need to tap into<br />
that potential! 4<br />
Hosting the show within the context of the<br />
Faculty of Medicine and Dentistry created<br />
a space where the realms of fine art and<br />
health education could merge. Science and<br />
technology are already strongly emphasized<br />
in health education, but students who<br />
integrate the arts into their busy schedules<br />
must be self-motivated. 5 The Art Show<br />
was a way to recognize this effort and<br />
celebrate the results. In total, forty works of<br />
visual art were displayed, including acrylic<br />
painting, photography, sketches, sculpture,<br />
collage, and a short film. Proceeds were<br />
donated to the Multicultural Health Brokers<br />
Cooperative to establish an “engagement<br />
fund” which helps newcomers to Canada<br />
access early learning programs and healthrelated<br />
services for their young children. 6<br />
The weeklong exhibit was displayed in the<br />
John W. Scott Health Sciences Library at the<br />
University of <strong>Alberta</strong>, where the pieces could<br />
be viewed by students and faculty from<br />
across campus.<br />
The opening night event was a<br />
great example of the “determinants<br />
of health” in two ways. Firstly,<br />
the event modelled that “giving”<br />
doesn’t have to just be within the<br />
realm of our professional skills. By<br />
sharing our talents and our gifts,<br />
you can generate many things<br />
for the community – including<br />
20<br />
fundraising as that event did.<br />
Secondly, the event generated<br />
a sense of social support and<br />
community in general among the<br />
medical and dentistry students.<br />
This kind of social connectedness<br />
and gathering for a cause is so<br />
important for all communities –<br />
including students. It provides<br />
a type of resiliency that is really<br />
necessary. 4<br />
My hope is that those students who struggle<br />
to find space for art will continue to create.<br />
In an environment where the function of<br />
fine art can be questioned, it becomes even<br />
more important to continue to support<br />
and encourage this effort. “The linkages<br />
between arts and the sciences have been<br />
proven in research for years, but how to<br />
‘live’ this can be a bit challenging in the way<br />
that our social structures seem to be built,”<br />
explains Felix. 4 The structure of medical and<br />
dentistry school are especially challenging<br />
in this regard. For Katie, the struggle to<br />
find space for art as a medical student has<br />
been difficult; “The only consolation I find<br />
is knowing that [photography] will always<br />
be there, waiting, for me to tend to the<br />
process again.” 2<br />
As a community it is critical that we<br />
continue to affirm the insights and<br />
perspectives expressed through art. “With<br />
art, it is possible to transcend the limitations<br />
of traditional scientific inquiry and to explore<br />
a more human and holistic perspective,”<br />
writes Jessie Breton, resident physician<br />
and contributing artist at the event. 7 Those<br />
working and studying in health sciences<br />
possess a rich and valuable diversity of<br />
talent and perceptiveness that unfortunately<br />
often goes unrecognized and untapped. 8<br />
“Arts can contribute a lot to how we<br />
practice and achieve success in the health<br />
sciences – how we strive to create healthy<br />
conditions and achieve health with our<br />
clients.” 4 For students themselves, making<br />
art can be a powerful form of self-care; the<br />
process can be a way of relieving stress,<br />
learning concepts, processing emotions<br />
and experiences, and maintaining balance.<br />
Taking that next step of sharing our artwork<br />
allows us to draw strength and inspiration<br />
from one another.<br />
Art, literature, drama and music,<br />
in all their many forms, are<br />
expressions of human creativity;<br />
they reflect human joy and sorrow,<br />
and human celebration and<br />
reflection... They do not merely<br />
have usefulness in contributing<br />
to the development of ends other<br />
than themselves: they also have an<br />
intrinsic value in their own right. 9<br />
With the support of the Arts & Humanities<br />
in Health & Medicine (AHHM) Program at<br />
the University of <strong>Alberta</strong>, 10 the Medical &<br />
Dental Student Art Show will run again in<br />
April, 2012. I invite you to attend this special<br />
event and be a part of celebrating students<br />
who find the time to make art.<br />
The following excerpts are by students who<br />
were featured at this year’s Art Show:<br />

Size: 36x34in<br />
Artist’s Statement:<br />
Our society has traditionally believed in<br />
the photograph’s ability to record the truth<br />
in a moment past. If this can still be the<br />
case, then my unadulterated photographs<br />
represent the history of my personal struggle<br />
to gain control in life. For many of us there<br />
are events in our lives that never surface to<br />
the public or even to our closest friends. We<br />
smile and tidy things up but somewhere in<br />
there is a piece of chaos that goes unspoken.<br />
On the whole, we look put-together but<br />
on closer inspection we’re people who deal<br />
with stress, difficult relationships, illness,<br />
trauma and death. These trees touch upon<br />
the power of human control, or a lack<br />
thereof. They are my attempt to wield and<br />
instrument against the natural and unruly<br />
world. The imperfections in the piece are the<br />
traces of humanity that reveal the truth in all<br />
this: control over life is an illusion.<br />

Artist’s Statement:<br />
Keeping up with one’s hobbies during<br />
medical school is sometimes perceived as a<br />
compromise, but is a genuinely constructive<br />
activity that tends to produce a greater level<br />
of satisfaction and enjoyment throughout<br />
one’s career. The importance of ‘balance’<br />
is emphasized so heavily during medical<br />
training that, at times, it seems clichéd.<br />
However, after only one year of medical<br />
school I recognize the importance of having<br />
a life outside of Medicine. In my case,<br />
drawing has been a refreshing reprise from<br />
schoolwork on many occasions. Studying so<br />
hard without any physical manifestation of<br />
the hours you’ve put in can be frustrating,<br />
and studying the same subject for days<br />
becomes tedious. Drawing allows one to be<br />

creative, and actually produce something<br />
tangible. Furthermore, I find that finishing<br />
a piece of art into which I’ve put a lot of<br />
thought and effort is an extremely fulfilling<br />
activity.<br />

Vina Nguyen is a medical student in the<br />

Artist’s Statement:<br />
In medicine, we can become caregivers<br />
holding the last source of hope for our<br />
patients. Unfortunately, sometimes we<br />
do not realize that what we say or do can<br />
greatly impact a patient’s quality of life,<br />
their perception of their illness, and their<br />
perseverance to survive and endure difficult<br />
times in their life. In these situations I<br />
find that art can help ground and open<br />
my perception of the world. Art also helps<br />
me realize my biases and misconceptions<br />
before I act upon them, so that I can become<br />
a more connected healer. As healers we<br />
are exposed to a multitude of experiences,<br />
from loss and grief, to anxiety and joy. Art<br />
can help us internalize all these emotional<br />
experiences so that we may learn and grow<br />
from them. In this way, I believe that art<br />
not only nurtures the heart and soul, but it<br />
may also nurture the mind by encouraging<br />
creative, open thinking. Art for me is an<br />
important part of medicine: it satiates my<br />
need for creativity, ensures there is balance<br />
in my life, and exercises my mind to stay<br />
open and understanding.<br />

On the value of narrative reflective practice: A personal reflection<br />
Debbi Andrews, MD<br />
Divisional Director and Associate Professor, Division of Developmental Pediatrics,<br />
Faculty of Medicine and Dentistry, University of <strong>Alberta</strong>, Edmonton, Canada<br />
Correspondence to Dr. Debbi Andrews: Email: andrewsd@ualberta.ca<br />
In December 2010, I attended a workshop<br />
on Narrative Reflective Practice (NRP)<br />
hosted by the Health Sciences Education and<br />
Research Commons (HSERC) and Centre<br />
for Teaching and Learning (CTL) at the<br />
University of <strong>Alberta</strong>. The workshop facilitator,<br />
Dr. Hedy Wald from Brown University,<br />
asked participants to prepare and share short<br />
descriptions of their own experiences using<br />
narrative writing exercises with students.<br />
As I started to work on the customary 3-5<br />
Powerpoint slides, I realised that there was very<br />
little reflection involved in what I was proposing<br />
to present, just a bone-dry list of what was done.<br />
This didn’t capture the experience of facilitating<br />
an NRP session, and I doubted it would spark<br />
any reflection in the workshop group. I deleted<br />
the slides and took out a pen. The following<br />
is my own narrative reflection that I read to<br />
the group.<br />
I am no orator, but I am a writer. I choose<br />
today to talk about my own experience in<br />
teaching and facilitating narrative practice in<br />
the form of a read narrative.<br />
For the past two years I have facilitated<br />
small group narrative reflective practice<br />
sessions for first year medical students as<br />
part of their Patient-Centred Care course. 1<br />
These sessions are part of an initiative to<br />
insert exercises in reflection at key points<br />
during medical school and residency at the<br />
University of <strong>Alberta</strong>. The themes presented<br />
in the first year include professional identity,<br />
professionalism and biomedical ethics. Later<br />
the students have opportunities to reflect on<br />
their encounters with patients and staff in<br />
clinics and on the hospital wards. I confess<br />
that I was initially drawn to participating<br />
in these sessions for somewhat selfish<br />
reasons—I am a writer and wanted a way to<br />
integrate my own writing background with<br />
teaching. Now, because of two very different<br />
experiences in facilitating these groups<br />
from last year to this one, I am even more<br />
committed to the importance of reflective<br />
writing in medical training. I have a better<br />
understanding of what the act of writing can<br />
mean for achieving understanding. Let me<br />
explain what I mean.<br />
The students’ assignment was to write, then<br />
share aloud, a one page narrative on the<br />
topic of medical identity—what it means<br />
to become a doctor, both as a general<br />
process and how this might apply to them<br />
as individuals. For each session the writing<br />
prompt was a film that was viewed by the<br />
entire first year medical class, followed by<br />
a faculty panel who reflected on some of<br />
the issues from the film and an interactive<br />
question and answer session. Afterwards,<br />
the students wrote their own brief reflective<br />
responses to the film, and then, two days<br />
later they shared those reflections in<br />
facilitated small groups.<br />

As often happens for busy clinician teachers,<br />
my schedule precluded my facilitating at the<br />
same point in the course two years in a row,<br />
so the material discussed differed from one<br />
year to the next. Last year I had facilitated<br />
a small group after they watched the movie<br />
The Doctor (1991) starring William Hurt<br />
as a callous surgeon who discovers he has<br />
cancer and must become a patient. 2 The<br />
experience changes the way he views his<br />
patients, his family and his life. Although the<br />
film was fictional, it was based on a real-life<br />
physician’s memoir. This year I facilitated a<br />
group discussion of The Doctors’ Diaries, a<br />
condensed version of the Nova documentary<br />
series which followed eight Harvard medical<br />
students for fifteen years, from the first year<br />
of medical school, through residency, and<br />
into practice. 3<br />
Facilitating the two groups was very<br />
different. With last year’s group, the<br />
narratives contained significant insights<br />
about the film The Doctor. Topics presented<br />
in the students’ reflections included personal<br />
experiences of illness, family support, worklife<br />
balance, spirituality, and the concept<br />
of duty assumed upon entering a caring<br />
profession. The students read descriptions<br />
of their own doctors, and also the kinds of<br />
doctors they wanted to be. Their writing<br />
styles and abilities were varied, but they<br />
honoured each others’ stories, and the<br />
discussion was very rich.<br />
Not so with this year’s group. At first, I<br />
thought it was because of the material<br />
used for this particular session—because<br />
it was a documentary, not a story, or<br />
perhaps because it was about a prestigious<br />
ivy-league school, and not “here”. Yet<br />
it was clear from the kinds of questions<br />
and comments made during the panel<br />
discussion that the students had been<br />
emotionally engaged with these real people,<br />
and threatened by the very real stresses the<br />
Harvard medical students experienced as<br />
depicted in the film. There was something<br />
else going on in my group’s session. I<br />
should have noted it then and put a stop<br />
to it because what was done was not what<br />
was intended, but I didn’t figure it out until<br />
I myself reflected on the process for today’s<br />
workshop.<br />
This is what happened. The first student<br />
took out what I thought was his written<br />
narrative, and instead of reading it<br />
aloud, he presented his ideas in a casual<br />
conversational style as in any other group<br />
discussion. When I glanced at his paper, I<br />
saw it contained some thoughts scrawled<br />
across the page in point format, like<br />
speaker’s notes. Not a narrative. The next<br />
student, who had written a full narrative,<br />
22<br />
started to read but when she got to a<br />
sentence that was similar in its theme to<br />
the first student’s, she followed his lead and<br />
apologetically abandoned her text to wing<br />
it—“Oh, yeah, I sorta felt the same way,”<br />
and “I’ll skip that because it was the same as<br />
he said,” and so on, essentially stripping her<br />
response of her individual writing style and<br />
all the personal narrative details—especially<br />
the careful selection of WHAT TO SAY.<br />
Those two students set the tone of the<br />
session, and the other students followed<br />
suit. No one read more than a few<br />
sentences. Yes, there was a good discussion<br />
overall, but the responses became muddled<br />
together, and at the end I could not<br />
identify one distinctive story. Why had this<br />
happened? The groups were the same size<br />
and equally varied in their backgrounds<br />
and experiences, we’d started with the same<br />
introductions process and the students<br />
seemed comfortable with each other.<br />
The session left me unsatisfied. I felt I had<br />
somehow not done my job as facilitator<br />
although I wasn’t able to figure out what I<br />
had done wrong. I recalled the individual<br />
student voices from the year before in<br />
their carefully chosen words and phrasing<br />
and compared that to the bland “Me,<br />
too”-ing of this year’s group. Even one<br />
young woman who’d admitted during<br />
the introductions to having participated<br />
in a poetry—yes, POETRY—group as an<br />
undergraduate, became self-conscious of<br />
her written attempts to create a voice and<br />
left off reading her text for the comfortable,<br />
conforming anonymity of chat.<br />
Perhaps you now can see why I have<br />
chosen to read this narrative script instead<br />
of casually discussing my experiences<br />
with reflective writing. Writing and oral<br />
language are not the same. Oral language,<br />
by its speed and spontaneity, is inaccurate.<br />
We speak off the cuff and in the moment,<br />
trying to communicate with someone who<br />
is physically present. This works because<br />
we have instantaneous feedback from our<br />
communicative partners—in their body<br />
language, their attentiveness to the message,<br />
the quality of their response. If we’re not<br />
making sense, we know it—the listener asks<br />
questions to clarify the message, and based<br />
on these questions, we change what we are<br />
saying—repeating, perhaps paraphrasing,<br />
altering word choice, even backtracking<br />
or simplifying to arrive at understanding.<br />
Speech language pathologists with whom<br />
I work call this process “narrative repair.”<br />
People who are good communicators don’t<br />
wait for the questions from the listener<br />
to begin this process. They’re in there at<br />
the first frown or lifted eyebrow, when the<br />
internal “uh-oh” tells then they’d better<br />
go back and fix things, or they’ll lose their<br />
audience. They are already starting to pick<br />
up the pace before the increasing frequency<br />
of yawns tells them that they are being<br />
boring. This does not happen with written<br />
text.<br />
In writing, the repair is in the edits and<br />
must be done before the “speaker” ever<br />
“speaks” his piece, because any clarifying<br />
feedback will be removed in time and space.<br />
This forced clarification creates a powerful<br />
communication tool. Spontaneous oral<br />
language is ephemeral, unless recorded or<br />
written down. We as listeners are left with<br />
an impression of someone else’s truth. In<br />
writing we aim to achieve our own truth.<br />
Writing should stand alone.<br />
In John Sandars’ 2009 article in Medical<br />
Teacher he states that reflection is a<br />
metacognitive process. 4 I would add that<br />
editing is also a metacognitive process—it<br />
requires us to think about language, to<br />
deliberate and become deliberate in our<br />
approach to a communicative task. The<br />
act of writing slows us down. We carefully<br />
consider the ways we use words to avoid<br />
the possibilities for ambiguity that can<br />
ambush the sought-after clarity and ultimate<br />
presentation of our personal truth. When<br />
we submit our final written draft, we are no<br />
longer figuring out what we want to say. We<br />
know. We say, “THIS is what I think. THIS<br />
is what I feel. THIS is what I believe.” NOT<br />
“I’ll say this about that”, but “THIS is what I<br />
WANT to say about THAT”.<br />
This is the lesson of narrative reflective<br />
practice, and should be our focus when<br />
we teach this to others: the deliberate<br />
consideration of what we think and feel and<br />
believe, and the value of communicating<br />
these thoughts and feelings and beliefs<br />
through the deliberate consideration of the<br />
written word. The narrative reflective<br />
process was not as effective in my small<br />
group this year, at least partially because<br />
I let the discussion stray from the written<br />
word. Despite the students’ emotional<br />
engagement in The Doctor Diaries, the<br />
superficial conversations did not capture<br />
their individual reflections or link the<br />
experience of viewing the film with their<br />
own stories. The discussion never reached<br />
down to the very deep issues that had arisen<br />
from the film.<br />
Next year I know what to do. If any of the<br />
students wander away from their requested<br />
narrative reflection, I am going to stop<br />
them and say, “Please read what you wrote,<br />
because the words are important.”<br />

Abstract<br />
Marie Cave and Jean Clandinin describe<br />
their experience of bringing narrative<br />
reflective practice into medical education<br />
at the University of <strong>Alberta</strong>. In this account<br />
they discuss their experiences with the<br />
process of curriculum change, as well<br />
as some of the unique characteristics<br />
of narrative reflective practice in<br />
medical education.<br />
Marie-Thérèse Cave:<br />
There are certain moments that turn out<br />
to have important consequences. Except<br />
for flashes of intuitive prescience, rarely<br />
is one able to predict which events will<br />
turn out to be the momentous ones.<br />
Only in retrospect can one appreciate the<br />
significance of the beginning points, turning<br />
points, and contingencies that characterize<br />
the introduction of a curricular innovation<br />
in medicine. This is the way it was for the<br />
individuals in the story that follows.<br />
I suppose I should be the person to begin<br />
the story. However, for me, it didn’t begin<br />
with the cup of tea. It began weeks before,<br />
one morning, when I walked into my office<br />
in the Department of Family Medicine to<br />
find a journal on my desk.<br />
The journal was the latest edition of<br />
Reflective Practice: International and<br />
Multidisciplinary Perspectives. The title<br />
itself was enough: This was the first<br />
journal to address the work in which<br />
I had been involved for more than ten<br />
years. My own education in how to be a<br />
reflective practitioner, and how to facilitate<br />
reflection, began in Liverpool, during my<br />
undergraduate work in education. At the<br />
time I was also personally engaged in<br />
exploratory learning through the work<br />
of John Dewey, and his accounts of how<br />
learning takes place. My self-education<br />
included Donald Schon’s writings and also<br />
that of more local reflective practitioners,<br />
like Hawkins and Shohet, in nearby Bath.<br />
My education continued later, in Bristol, in<br />
my second career as a counselor and then<br />
as a supervisor of counselors and therapists.<br />
My clinical work began with educating and<br />
supervising the practice of counselors and<br />
therapists in Bristol, England. My practice<br />
then expanded to involve physicians, mostly<br />
family doctors, who were seeking a way<br />
to reflect upon the challenge of delivering<br />
optimal care to patients and patients’<br />
families, and themselves. As a practitioner,<br />
my interest grew from trying to understand<br />
how students learn to understand, to how<br />
I, and my peers, made meaning of our<br />
experiences with clients.<br />
When I came to the University of <strong>Alberta</strong> I<br />
was able to continue some of this work, as<br />
the College of Family Physicians of Canada<br />
had recently announced their expectation<br />
that residency programs develop curricula<br />
in behavioural medicine. This was to be a<br />
curriculum that included “opportunities<br />
for reflective practice with skilled and<br />
sensitive teachers of family medicine.” As<br />
the Behavioural Medicine coordinator within<br />
the family medicine residency program,<br />
I incorporated a “reflective practice”<br />
pedagogy into the curriculum.<br />
In the 15 years that followed, I continued<br />
listening to physician stories, trying to help<br />
resident physicians make meaning of their<br />
experiences. Some of the medical educators I<br />
met shared my interest in reflective practice,<br />
but much of the work in which we were<br />
involved together focused on developing<br />
curricula in communication skills and the<br />
practice of patient-centered care.<br />
I opened the new journal eagerly. I was<br />
keen to discover if it was a place in which<br />
I could share my interest in reflective<br />
practice, and read of others in the midst of<br />
similar work in medicine. An immediate<br />
scan revealed interesting work being done<br />
in several of the “helping professions” – in<br />
nursing, education, and also, surprisingly, in<br />
business – but none of the articles focused<br />
on medicine. I then read the list of those on<br />
the international editorial board, and I was<br />
surprised to see the name of a professor<br />
at the University of <strong>Alberta</strong>, in the Faculty<br />
of Education. Instinctively I picked up the<br />
university directory and made a call. “Dr.<br />
Jean Clandinin is in Taiwan,” responded her<br />
secretary, and then she added “you can leave<br />
a message if you like.” So I did.<br />
d. Jean Clandinin<br />
The message from Marie Cave came in<br />
the fall of 2003 while I was in the midst<br />
of planning what eventually became the<br />
Handbook of Narrative Inquiry: Mapping<br />
a Methodology. 1 The handbook was to be<br />
interdisciplinary and inter-professional, and<br />
I had a lot to learn. While I knew editing<br />
a research methodology handbook for<br />
a major international publishing house<br />

<strong>MUSA</strong>
<strong>MUSA</strong><br />
was going to be a lot of work, I also knew<br />
the handbook mattered to me. I have<br />
spent all my academic life on developing<br />
a conceptualization of professional<br />
knowledge; what we termed “personal<br />
practical knowledge.” We conceptualized<br />
this way of thinking about professional<br />
knowledge as embodied narrative<br />
knowledge: knowledge shaped by personal,<br />
institutional, cultural, familial, social and<br />
linguistic narratives. I knew that professional<br />
knowledge was shaped by, enacted,<br />
and lived out in multiple personal and<br />
professional contexts.<br />
My scholarly work is undertaken from a<br />
Deweyan conceptualization of experience. 2<br />
Because of our shared interest in Dewey’s<br />
work, I came to meet Donald Schon and had<br />
the opportunity to share ideas on reflective<br />
practice and on educating reflective<br />
practitioners. While Donald Schon did not<br />
work from a narrative conceptualization of<br />
reflective practice or from narrative notions<br />
of practitioner knowledge, we shared a deep<br />
commitment to the work of Dewey and to<br />
how Dewey’s works might help us move<br />
forward in professional education.<br />
My long interest in working with<br />
practitioners in reflective ways led to the<br />
invitation to join the editorial board of<br />
Reflective Practice. When I returned from<br />
Taiwan, I received the message that Marie<br />
Cave wanted to talk about reflective practice.<br />
I agreed to meet her for tea. I had no idea,<br />
beyond her interest in my work on the board<br />
of Reflective Practice, what the meeting would<br />
be about. I was intrigued, however, with<br />
learning more about medical education. My<br />
daughter-in-law is a physician and my son<br />
had accepted a position in a well-known<br />
faculty of medicine.<br />
This phone call from Marie Cave had<br />
serendipitously coincided with my being<br />
reminded of Rita Charon during my editorial<br />
work for the Handbook. I first met Rita<br />
Charon when I was a beginning faculty<br />
member at the University of Calgary. Rita<br />
was a member of an NIH taskforce who had<br />
come to the university to learn more about<br />
the possibilities of engaging in qualitative<br />
research into the experiences of geriatric<br />
caregivers. Their 1987 visit occurred just as<br />
my colleague, Michael Connelly, and I were<br />
completing our book Teachers as Curriculum<br />
Planners: Narratives of experience. 3 I was not<br />
expecting Rita’s interest in stories but, as we<br />
talked over those three days, Rita spoke of<br />
physicians’ stories. She was intrigued by how<br />
Michael and I were suggesting a split page<br />
method of keeping research field notes: on<br />
one side of the page, field notes were written<br />
which documented events and dialogue<br />
24<br />
and so on; on the other side of the page, we<br />
wrote our researcher reflections on what was<br />
happening to and for us. We had not been<br />
in contact for many years but I remembered<br />
her well because of our shared interests in<br />
the stories professionals told.<br />
And so it all began with a cup of tea.<br />
Conversation over Tea<br />
Marie-Thérèse Cave and<br />
D. Jean Clandinin<br />
We agreed to meet over tea in the teahouse<br />
in the university hospital at the end of a<br />
long and busy day for each of us. Raised on<br />
two different continents, we learned we had<br />
much in common. Born in the same month<br />
in the same year, we had both begun our<br />
professional careers in elementary education<br />
and we had both become counselors. We<br />
both married soon after graduating and<br />
we both had sons the same age who were<br />
now married.<br />
We shared stories of our lives, as our<br />
life compositions had taken us on<br />
different paths: Jean’s into academia and<br />
Marie’s into delivering training courses<br />
and supervising therapists and health<br />
professionals. We connected around the<br />
work of Donald Schon and his ideas on<br />
reflective practice. 4 As we talked over tea,<br />
we were telling and listening to stories and,<br />
because there seemed promise here for a<br />
working relationship, we were interested<br />
in possible ways of working together. Here<br />
in the hospital’s teahouse we were finding<br />
resonance between our stories and we were<br />
also beginning to imagine how we might<br />
compose a new story, together. We were<br />
both interested in the processes of becoming<br />
a physician and both wondered about the<br />
learning experiences that shaped physicians<br />
along the way.<br />
As we composed a story of what we might<br />
do together, we decided to explore the<br />
possibility of doing some narrative work<br />
together. Jean had recently read Susan Florio<br />
Ruane’s work about an autobiographical<br />
book study with beginning teachers. 5<br />
We wondered what would happen if we<br />
gathered a group of beginning physicians to<br />
read autobiographies and memoirs written<br />
by physicians. We imagined this study could<br />
be a starting point for further collaborative<br />
inquiries into the world of clinical practice.<br />
The time was right, not only in medical<br />
school, but in the larger field of research<br />
and professional education, where the ideas<br />
of narrative inquiry and narrative reflective<br />
practice were taking hold. There was a<br />
narrative turn occurring across disciplines.<br />
As we tentatively planned the small<br />
study that would bring us together as<br />
co-researchers, we arranged to meet<br />
the Associate Dean for Undergraduate<br />
Education. We proposed a small qualitative<br />
study in which the participants would<br />
read a series of physician-authored<br />
autobiographical books that would serve<br />
as triggers for narrative reflections on their<br />
own practices. The study would involve<br />
undergraduate students beginning their<br />
clerkships, residents, and beginning family<br />
physicians. While this was not a narrative<br />
inquiry, we wanted to think narratively<br />
about the interwoven ideas of knowledge,<br />
context, and identity in professional practice.<br />
We both saw this as a way to learn about<br />
each other as researchers, as well as to learn<br />
about narrative reflective practice as a way<br />
to think about medical education. We were<br />
curious to learn about what happens to<br />
physician learners as they progress through<br />
the medical curriculum into practice.<br />
There was also room to explore different<br />
pedagogical approaches to learning around<br />
professionalism and ethics. The Associate<br />
Dean for Undergraduate Education, along<br />
with postgraduate program directors, was<br />
particularly interested in these areas of<br />
the curriculum and the possible impact of<br />
reflection on narratives of practice.<br />
The First Study: Beginning<br />
the Journey to narrative<br />
Reflective Practice.<br />
In our study, participants read one book<br />
a month and then shared their responses<br />
to the stories of the physician authors. We<br />
planned five sessions over a six-month<br />
period. The books were selected to serve as<br />
triggers for the participants’ own stories.<br />
As the research progressed, Jean continued<br />
to edit the Handbook of Narrative Inquiry. As<br />
part of her reading, she read Rita Charon’s<br />
edited book (with Martha Montello) on<br />
narrative in medical ethics. 6 Marie located a<br />
web-based video demonstration of a parallel<br />
chart group, facilitated by Rita Charon. In<br />
this demonstration, medical student clerks<br />
completing their internal medicine clerkship<br />
rotation at Columbia Medical School are<br />
seen coming together to read aloud their<br />
written reflections on a patient encounter.<br />
As we worked together on the analysis<br />
and interpretation of data from our first<br />
study, we decided to design another study,<br />
this time with family medicine residents.<br />
This study would draw on Jean’s previous<br />
work on narrative inquiry, as well as on<br />
Rita Charon’s work with parallel charts. We<br />
decided to invite Dr. Charon to come to the<br />
university as a visiting scholar to further<br />
explore the use of clinician narratives as an<br />
aid to reflection on practice.<br />

The arts and Humanities in<br />
Medicine Program<br />
Synchronistically, the Faculty of Medicine<br />
& Dentistry was launching a new Arts &<br />
Humanities in Health & Medicine (AHHM)<br />
program. Both of us were serving on the<br />
planning committee for the launch of the<br />
program. When Verna Yiu heard that we<br />
had invited Dr. Rita Charon to visit with us<br />
to discuss our shared interest in narrative<br />
reflective practice, she suggested we<br />
combine our purposes. A renewed invitation<br />
was extended to Dr. Charon as a visiting<br />
professor and also as a keynote speaker for<br />
the AHHM program launch.<br />
We were very excited to learn what Dr.<br />
Charon might bring to the faculty and to<br />
our research. At around this time, Alan<br />
Thomson, a well-known gastroenterologist,<br />
spoke with Jean and asked for assistance<br />
with some curriculum design work. On the<br />
day of the launch, Jean agreed to meet with<br />
Alan to share some resources she thought<br />
might be helpful to him. Jean was carrying a<br />
copy of Narrative Medicine, Charon’s book. 7<br />
As Alan and Jean discussed what Jean<br />
brought for him, he noticed Charon’s book<br />
and asked about it and about the work in<br />
narrative Jean and Marie were doing in<br />
Family Medicine. Before Jean left Alan’s<br />
office, she had promised to send him some<br />
articles and chapters on narrative inquiry<br />
and some of her work with Marie as well as<br />
a chapter from Charon’s book.<br />
The launch was well received, and the days<br />
following Charon’s visit led to an expansion<br />
of interest in narrative medicine and<br />
narrative reflective practice and a promise<br />
to consider the possibility of visiting Dr.<br />
Charon in New York and attending her<br />
workshop at Columbia.<br />
The Forward Looking<br />
Story Unfolds<br />
While Alan Thomson had not been involved<br />
in Dr. Charon’s visit, he had been reading<br />
the literature Jean had sent him. He asked<br />
if he could host a dinner one evening to<br />
discuss narrative research possibilities<br />
for medical education. Those present at<br />
this dinner were Alan Thomson, Andrew<br />
Cave (the two physicians in the group),<br />
Marie and Jean. Naming our conceptual<br />
framework ‘Narrative Reflective Practice’, we<br />
began to imagine how narrative reflective<br />
practice could become part of the medical<br />
curriculum. We also began to imagine<br />
research possibilities that would accompany<br />
the curriculum change. The main purpose of<br />
the research was to establish the difference,<br />
if any, narrative reflective practice played in<br />
the professional development of physicians<br />
and in medical education for physiciansin-training.<br />
This represented a continuation<br />
of Jean’s work using narrative inquiry<br />
methodology to explore the process of the<br />
professional formation of teachers and<br />
administrators. That evening over dinner we<br />
began work on a research agenda focused<br />
on narrative inquiry and narrative reflective<br />
practice in medical education. We were<br />
continuing a narrative turn in the Faculty of<br />
Medicine & Dentistry.<br />
Marie was stunned by the alacrity with<br />
which the small group began planning.<br />
All present were keen to discuss narrative<br />
research possibilities for a narrative reflective<br />
practice curriculum in the medical school<br />
and for the faculty. It was decided that in<br />
residency education we would begin by<br />
approaching three disciplines: internal<br />
medicine, family medicine and pediatrics.<br />
Our small research group already had<br />
physician involvement in family medicine<br />
and internal medicine. We decided to invite<br />
Verna Yiu as the pediatrician member of our<br />
research team, because of her leadership at<br />
the time in the Arts & Humanities in Health<br />
& Medicine program and her involvement<br />
in supporting Dr. Rita Charon’s visit to the<br />
University of <strong>Alberta</strong>.<br />
The following day we sent an email to the<br />
then Dean, Tom Marrie, and were surprised<br />
to receive an immediate response. He<br />
requested that we lead the delivery of a<br />
curriculum in narrative reflective practice<br />
in all four years of the undergraduate<br />
medical curriculum. Jean and Marie met,<br />
again over tea, and further sketched out<br />
a developmental curriculum in narrative<br />
reflective practice. A subsequent meeting<br />
of our small group with the dean allowed<br />
us to more fully inform him of our plans.<br />
We communicated the need for faculty<br />
development and gained funding for some<br />
of us to visit Columbia Medical School in<br />
New York and attend Dr. Charon’s two-day<br />
narrative medicine workshop. Funding<br />
also came from the Department of Family<br />
Medicine which had already supported<br />
some of our early research projects<br />
Other academic physicians were learning<br />
about, and expressing interest in, narrative<br />
reflective practice. We invited several of<br />
them to become champions of narrative<br />
reflective practice and to become involved<br />
with the recently formulated curriculum<br />
plan. In these early days, those involved<br />
were developing individual understandings<br />
of narrative medicine and narrative<br />
reflection on practice. Some had an interest<br />
in promoting an aesthetic and humanistic<br />
appreciation of the reading, writing,<br />
and listening to stories of patients’ and<br />
physicians’ lives. Others were primarily<br />
interested in researching the possibilities<br />
of narrative reflective practice as a tool,<br />
or pedagogical approach in physician<br />
formation. Still others saw the value of<br />
narrative inquiry as a research methodology<br />
in the acquisition of a deeper knowledge of<br />
patients’ and physicians’ experiences, and<br />
by so doing, increasing the evidence basis<br />
for clinical decision making. None of these<br />
understandings were mutually exclusive,<br />
but it was becoming increasingly evident<br />
that we needed a common language, so<br />
that we could better articulate our purposes,<br />
especially if we were to achieve our goal<br />
of engaging students and physicians in a<br />
cohesive developmental narrative reflective<br />
practice curriculum within the medical<br />
school. Faculty development was a priority.<br />
Faculty development<br />
We began faculty development with a<br />
residential course over three weekends<br />
spread out over several months. The setting<br />
was a retreat located outside of the city.<br />
Each weekend started with a review of<br />
pre-assigned key theoretical resources.<br />
These included work by John Dewey,<br />
Mark Johnson, Alasdair MacIntyre, Robert<br />
Coles, Mary Catherine Bateson, and David<br />
Carr. The rest of each weekend was spent<br />
in experiential learning about narrative<br />
reflective practice. Given that narrative<br />
reflective practice is about stories lived<br />
and told, 8 we invited participants to access<br />
their tacit knowledge of practice through<br />
the telling and re-telling of their stories<br />
of experience.<br />
Working within the three dimensional<br />
narrative inquiry space, they learned to<br />
attend to the past, present and future<br />
directions of their stories (temporality); to<br />
attend to their inner emotions and moral<br />
judgments as well as to unfolding events<br />
(sociality); and to the place or places where<br />
events were occurring. 8 They learned the<br />
importance of “wondering questions,” as an<br />
aid to the facilitation of the inquiry. Further<br />
faculty development courses were planned<br />
and delivered and, after consultation with<br />
various curriculum committees, Narrative<br />
Reflective Practice pedagogies were<br />
eventually launched, by the champions, in<br />
the first three years of the undergraduate<br />
medical curriculum.<br />
In their first year, students have little<br />
clinical experience. To assist in meeting the<br />
objectives related to communication in the<br />
Patient Centred Care course, we introduced<br />
films (visual narratives) as a means of<br />
facilitating the narrative reflection of each<br />
University of <strong>Alberta</strong> Health Sciences Journal • April 2012 • Volume 7 • Issue 1 25<br />

<strong>MUSA</strong><br />
physician learner. Following full-length<br />
film screenings, a panel of faculty members<br />
modeled narrative reflection by sharing<br />
their reflections on the visual narrative with<br />
the students. Two days later, the students<br />
shared their written narrative reflections<br />
on the film in facilitated small groups. A<br />
series of wondering questions, arising from<br />
the visual narrative and based around the<br />
three dimensions of narrative inquiry (place,<br />
temporality, sociality) assisted in the process<br />
of narrative reflective practice. Student<br />
feedback helped to inform the ongoing<br />
evolution of the Narrative Reflective Practice<br />
(NRP) module in our first year Patient<br />
Centred Care course. 9<br />
In second year, Gilbert Scholars, physicians<br />
who work with second year students, were<br />
trained by Jean, Marie, and Alan Thomson<br />
to facilitate narrative reflective practice<br />
around listening to and inquiring into their<br />
experiences of “the patient’s story.” In the<br />
Gilbert Scholars’ course, students learn how<br />
to take a medical history, and learn how to<br />
perform a physical exam. A comparative<br />
research study was undertaken that involved<br />
having some small groups within the class<br />
meet for a second time with a patient and,<br />
in conversation, explore the patients’ stories<br />
of their illness experience. Each student<br />
then wrote, and shared with peers in their<br />
small group, a narrative reflection on the<br />
patients’ stories of their illness. The stories<br />
the second year students wrote showed how<br />
much they learned from attending closely<br />
to the stories that patients told of what<br />
was happening to them. We are hoping<br />
to repeat this study in the near future in<br />
order to establish conclusively if there is a<br />
difference in history-taking competencies<br />
between those students who participate in<br />
the narrative reflective practice intervention<br />
and those who do not. In the meantime, we<br />
recently introduced additional sessions of<br />
our film-based NRP module into the second<br />
year Patient Centred Care course.<br />
In third year, when students begin their<br />
clinical practice, we found that narrative<br />
reflective practice begins to impact the<br />
learner physicians’ professional identity<br />
formation. 10 Students in family medicine<br />
and surgery clerkship rotations now<br />
participate in narrative reflective practice<br />
activities. In surgery, clerks write a<br />
narrative reflection on a surgery clerkship<br />
experience. 11 In family medicine, student<br />
clerks write parallel charts of a clinical<br />
encounter in practice. 10 As described by Rita<br />
Charon, the parallel chart is the place where<br />
the physician learner writes those things<br />
that don’t belong in the chart “but need<br />
to be written somewhere”. 7 This exercise<br />
affords the learner opportunities for both<br />
26<br />
reflection and reflexive thinking around<br />
their responses to the clinical encounter.<br />
In their family medicine rotation, students<br />
share their written reflections in facilitated<br />
small groups, using the three dimensional<br />
narrative inquiry dimensions to inquire<br />
into their stories of experiences as written<br />
in their parallel charts. In addition, some<br />
residents have been involved in facilitating<br />
the small groups we introduced in our<br />
first and second year Patient Centred Care<br />
course.<br />
Pilot studies have been completed in family<br />
medicine and internal medicine residency<br />
programs. 12,13,14,15,16 At this point, NRP has<br />
now been introduced in family medicine and<br />
surgery residency programs, and recently a<br />
Narrative Reflective Practice journal club has<br />
begun as a means of supporting continuing<br />
professional learning for academic and<br />
clinical faculty. In addition to the Narrative<br />
Reflective Practice initiatives described<br />
above, we are aware that preceptors who<br />
teach and guide learners in undergraduate<br />
and postgraduate programs are exploring<br />
various approaches to reflection, some of<br />
it narrative reflective practice. This new<br />
initiative marks the achievement of the goal<br />
of our original developmental curriculum<br />
plan—to become involved in all stages of<br />
medical education.<br />
To date there have been nine publications<br />
in peer reviewed journals, as well as invited<br />
contributions to a chapter On Longitudinal<br />
Integrated Clerkships, editors Poncelet A<br />
& Hirsch D in the forthcoming edition<br />
of “Alliance for Clinical Education’s (ACE)<br />
Guidebook for Clerkship Directors.” Ed. Bruce<br />
Morgenstern. There have been workshops<br />
and peer-reviewed presentations at medical<br />
education conferences, and also invited<br />
workshops and presentations. Our group<br />
of researchers and educators are now part<br />
of a global network of pioneers in narrative<br />
reflective practice within medical education<br />
– and the research is ongoing.<br />
Narrative reflective practice and narrative<br />
inquiry are relational. True to form, our<br />
journey into Narrative Reflective Practice<br />
medical education research began through a<br />
relationship – with a cup of tea. We believe<br />
this experiential and relational approach to<br />
learning is providing medical learners, at all<br />
stages of their journeys as physicians, with<br />
a sense of being engaged in a community of<br />
learning, as we each learn from one another,<br />
and also experience the unique opportunity<br />
to learn from the self, by making tacit<br />
knowledge explicit.<br />
In a packed curriculum and with busy<br />
clinical agendas, Bolton reminds us of<br />
the importance of noticing moments for<br />
structured reflection. 17 She references the<br />
observer and poet William Wordsworth who<br />
wrote, “there are in our existence spots of<br />
time…whence...our minds are nourished<br />
and invisibly repaired. Such moments<br />
are scattered everywhere.” 18 This reflects<br />
well the impulse and motivation that has<br />
compelled us forward, as we continue<br />
to explore the potential of NRP in our<br />
curriculum and collaborate together in<br />
contributing to new ideas and visions that<br />
might inform future directions for medical<br />
education.<br />

Abstract<br />
Through the use of drama and the art<br />
of storytelling, Robert Hawke has been<br />
sharing his journey of cancer diagnosis and<br />
treatment in a live, one-man comedic play<br />
entitled NormVsCancer. In the first person<br />
account below, Hawke describes how his<br />
play, when brought to patients, families and<br />
health professionals, was able to provide<br />
insight into his experience as a patient,<br />
and enrich patient centred care (PCC). This<br />
account also address how Rob’s play and<br />
his presence within the healthcare context<br />
has invigorated and drawn attention to the<br />
practice of PCC at the University Health<br />
Network, in Toronto, Canada.<br />
What if your nightmare was not a<br />
nightmare? What if your dreams were<br />
illuminating the possibilities of your life and<br />
the only thing to fear is how to live within<br />
those possibilities? This is my story such as<br />
it is.<br />
Five years ago I had thyroid cancer. It took<br />
me completely by surprise and I must say<br />
I was utterly unprepared for it. Diagnosis,<br />
surgery and recovery were tough, but what<br />
was most surprising to me was that this<br />
disease was so challenging in virtually every<br />
area of my life as it is with so many of us<br />
who deal with having cancer.<br />
I have worked as an actor and writer in<br />
comedy for years and shortly after surgery,<br />
I began writing and improvising the show<br />
that would become NormVsCancer. It wasn’t<br />
as clean cut as that of course - I didn’t wake<br />
up in the morning and say “and now I will<br />
write a significant piece about my experience<br />
that will hopefully resonate with others”. It<br />
was a lot more ragged than that. Alone in<br />
my apartment, I would become upset or sad<br />
and would just start acting out conversations<br />
between myself, and imaginary characters.<br />
Medical professionals might call this an<br />
interesting way of coping with a troubled<br />
psyche; my neighbours might have called<br />
it “batshit crazy”; I called it “theater”. I<br />
actually began to write this stuff down and<br />
form a structure around my ramblings that<br />
made some kind of sense. I managed to get<br />
the show partly written and knew I needed<br />
some help at that point to get any kind of<br />
finished piece.<br />
With the help of my friend Michael Cohen,<br />
we were able to co-create the first version<br />
of NormVsCancer and take it to the Prague<br />
Fringe Festival three and half months after I<br />
had surgery. I don’t recommend this. I pride<br />
myself on being prepared and professional;<br />
however, under the circumstances, we were<br />
under a very tight deadline and I just didn’t<br />
possess my usual levels of stamina, creativity<br />
and skill. Michael, as a consummate<br />
professional and director of the play, wanted<br />
to make the piece as good as it could be<br />
in the time we had. This made for a tense<br />
rehearsal period with me breaking down<br />
in tears on occasion and even throwing a<br />
chair across the room at one point. Now,<br />
please understand, I don’t believe that this is<br />
acceptable behavior at all. In fact, I think that<br />
any actor (or plumber or accountant) who<br />
engages in this kind of conduct deserves to<br />
be fired. My psyche was running amok at<br />
that point and I had all the coping skills of a<br />
rhino on acid.<br />
“Why did you do this?” you might ask.<br />
“Why not wait a couple of years for the dust<br />
to settle?” Well, it comes down to what I<br />
believe is a very basic human need, and<br />
that is the need to tell our stories. I HAD to<br />
talk about what had happened to me. Even<br />
dealing with my disease in a fictionalized<br />
way helped me to make some sense of it<br />
and process it. This was not obvious to me<br />
at the time. I thought I was just co-writing a<br />
funny show with some dramatic bits.<br />
Although this process was difficult and at<br />
times heart-wrenching, it was also a thrill<br />
to make something and share it with other<br />
people. It has been remarkably gratifying to<br />

find that folks in a similar situation could<br />
find resonance with their own experience,<br />
and by sharing the specifics of this one story<br />
we could find common ground and build<br />
community.<br />
I was quite nervous showing this piece<br />
to people who had been through cancer,<br />
thinking that I would be judged. After all,<br />
who was I to talk about this? These fears<br />
were put to rest after a performance for a<br />
small audience when a man in his fifties just<br />
came up to me without a word, hugged me<br />
and walked away.<br />
Throughout this theatrical process it has<br />
been my pleasure to talk with many cancer<br />
survivors and their families and time and<br />
time again I am struck by how folks who<br />
have been through something of this nature<br />
want to share their experience in order to<br />
process it in some way. More and more, we<br />
see patients coping with their traumatic<br />
experiences by expressing it in artistic ways.<br />
People paint, draw, act, sing, talk or choose<br />
any number of ways to communicate their<br />
experience. There is clearly value in this for<br />
patients. I don’t know how to measure it,<br />
quantify it or put it in a bottle, but it has<br />
28<br />
been my experience that many of us find it<br />
very useful.<br />
My wife works in healthcare, and through<br />
her, I was fortunate to meet some innovative<br />
and creative people at the University<br />
Health Network (UHN), Canada’s largest<br />
teaching, research and academic hospital.<br />
They identified a need for my show to be<br />
experienced by other patients and healthcare<br />
professionals alike.<br />
At UHN, Patient-Centred Care (PCC)<br />
is not just a set of words that hang on a<br />
plaque by the elevator on a ward; PCC is<br />
part of their guiding philosophy to practice.<br />
The philosophy encompasses the values<br />
of Respect, Human Dignity and Personas-Leader.<br />
The staff, which I have come to<br />
know and work with in light of our play,<br />
saw NormVsCancer as a wonderful vehicle<br />
to make clear the values of PCC. From my<br />
understanding, the staff at UHN has been<br />
engaged in iterations of PCC education<br />
over the past eight years. They have reached<br />
a crossroads, where the staff is not just<br />
hearing second-hand individual patient<br />
stories; they are yearning to hear from the<br />
patients themselves.<br />
Through NormVsCancer, I have been able to<br />
understand how to connect with my own<br />
healthcare team in way I never imagined.<br />
We have been able to stimulate lively and<br />
profound discussions with regard to PCC<br />
and how it is lived in practice. After each<br />
performance, patients and professionals<br />
are encouraged to tell their own stories<br />
and talk about what it was like for them in<br />
their own experience. You can practically<br />
hear the professional silos crumble and<br />
personal barriers fall, as folks share on a very<br />
human level what was for them a significant<br />
experience. It is an honour to be part of<br />
this process, to share with other patients<br />
of similar yet different experience and to<br />
be working with such dedicated health<br />
professionals who wish to advance PCC<br />
from the patient’s perspective.<br />
As a patient, these experiences have given<br />
me a tremendous amount of hope that we<br />
have the ability to make our healthcare<br />
system more effective, more caring and<br />
more human. How was I to know that<br />
my cancer diagnosis nightmare would<br />
awaken me to possibilities – to a life now<br />
illuminated?<br />
A bite into the media’s image of nursing in an apocalyptic world<br />

Abstract<br />
In this article, the portrayal of the nurse in<br />
popular media is compared and contrasted<br />
with that found in professional nursing<br />
publications. The current stereotypical<br />
image and role of the nurse in contemporary<br />
film is described based on the film Dawn<br />
of the Dead (2004). 1 Critical thinking<br />
skills; professional ethics and values; the<br />
autonomous role of nursing; and the<br />
image of nursing within specific contexts<br />
are all investigated and compared. The<br />
often inaccurate portrayal of nurses within<br />
popular media still continues to pose<br />
challenges to the nursing profession.<br />
However, concurrently, there is a trend<br />
towards increasing positive images of the<br />
nurse, and evidence of this is certainly seen<br />
in Dawn of the Dead.<br />
The image and role of the professional<br />
nurse are commonly portrayed in popular<br />
media. These representations impact public<br />
perception of the nursing profession. 2<br />
Unfortunately, there are significant<br />
differences between these fictitious<br />
portrayals of the nurse, and the realistic<br />
expectations of the profession outlined in<br />
nursing publications. According to Stanley,<br />
the current media trend is to represent<br />
the nurse in a more positive manner. 3 In<br />
analyzing the representation of nursing in<br />
the contemporary film, Dawn of the Dead,<br />
I have found evidence of such a trend.<br />
Through comparing the nurse in the film<br />
with professional nurses, I was able to<br />
identify some challenges affecting the<br />
creation of a positive nursing image.<br />
The movie Dawn of the Dead depicts a<br />
North American geographical area that<br />
has been overrun by zombies, who do not<br />
possess higher order thinking. The zombies<br />
in the film are preoccupied with attacking<br />
individuals who have not yet become<br />
zombies. The lead character in the film is<br />
a nurse named Ana Clark. Ana and a few<br />
other survivors flee to the nearby Cross<br />
Roads Mall. Increasing numbers of zombies<br />
begin to conglomerate outside the mall,<br />
attempting to enter the building and feed on<br />
the survivors.<br />
Critical Thinking Skills<br />
Throughout the film, there are casualties<br />
among the survivors in the mall. Some of<br />
these survivors incur bites from the zombies.<br />
Ana resourcefully sets up a triage center<br />
and begins to assess, treat, and comfort the<br />
newcomers. As would be expected from a<br />
professional nurse, she treats the patients<br />
with respect, compassion, and competence. 1<br />
Ana uses critical thinking skills to determine<br />
the mechanism of transmission of the<br />
zombie infection. Critical thinking can<br />
University of <strong>Alberta</strong> Health Sciences Journal • April 2012 • Volume 7 • Issue 1
e defined as making judgments about a<br />
situation using reflection, and integrating<br />
analysis, evaluation, and inference with<br />
knowledge. According to Profetto-McGrath,<br />
critical thinking is a necessary component<br />
for the professional nurse to exercise<br />
evidence-based practice. 1 Due to the threat<br />
of zombies and the characters’ isolation in<br />
the mall, it is not possible for Ana to employ<br />
evidence-based practice by consulting with<br />
experts. Furthermore, there is insufficient<br />
time for properly researched evidence to be<br />
generated and examined. 5 In the literature<br />
reviewing critical thinking skills and<br />
evidence based-practice, the professional<br />
nurse would ideally have opportunity to<br />
access such resources. Nevertheless, in the<br />
film, Ana uses the best evidence she has<br />
available to her in the given situation to<br />
guide her practice.<br />
In her triage center, Ana finds that one of<br />
her patient’s conditions is deteriorating<br />
quickly. She observes and astutely<br />
comments that the patient is cold, and that<br />
she has never seen such a bad infection<br />
without an accompanying fever. Within a<br />
couple of minutes, the patient dies. Ana<br />
assesses the patient for a pulse, checks<br />
the patient’s breathing, and determines<br />
that the patient is dead. Ana’s knowledge,<br />
assessment skills, and observations in this<br />
scene compare to those of a professional<br />
nurse. A few moments later, the deceased<br />
patient rises and begins to attack Ana. After<br />
Ana defends herself and kills her former<br />
patient (now a zombie), Ana evaluates the<br />
information available, uses inference and<br />
previous knowledge of her interactions with<br />
the zombies, and determines the mechanism<br />
of the zombie infection. She determines<br />
that the zombie infection is spread through<br />
bites. The critical thinking skills employed by<br />
the main character are comparable to those<br />
expected of a professional nurse, and are<br />
outlined in peer-reviewed nursing literature.<br />
Thus, this film portrays the role of the nurse<br />
positively, as comparable to roles outlined in<br />
professional literature.<br />
Professional nursing Values and<br />
Ethics<br />
The film takes place during a<br />
communicable-disease outbreak spread<br />
by zombie bites. The Canadian Nursing<br />
<strong>Association</strong> (CNA) states that: “During a<br />
natural or human-made disaster, including<br />
a communicable disease outbreak,<br />
nurses have a duty to provide care using<br />
appropriate safety precautions.” 4 Throughout<br />
the film, Ana abides by these regulations,<br />
using the resources she has available to her.<br />
Her actions in this respect are comparable<br />
to those expected of a professional nurse<br />
according to the CNA. 4<br />
After discovering the mechanism of<br />
transmission of the zombie infection in her<br />
triage center, Ana tells the group that Frank,<br />
one of her fellow survivors, has been bitten<br />
and should be quarantined immediately.<br />
Another character tells the group he thinks<br />
it is too dangerous to keep Frank alive.<br />
Our heroine immediately identifies and<br />
challenges the ethics of this situation: “What<br />
are we talking about here? Are we talking<br />
about killing him?” 1 Though this situation<br />
is not taking place within a formal nursing<br />
environment or practice, it addresses a<br />
number of nursing values and ethical<br />
responsibilities.<br />
Upon review of the Code of Ethics for<br />
Registered Nurses, I believe that Ana<br />
is encountering an ethical dilemma.<br />
Throughout the career of a professional<br />
nurse, ethical dilemmas and questions<br />
are encountered where the nurse has a<br />
difficult choice to make between two equally<br />
compelling courses of action. Ana is faced<br />
with this situation in the film. If Frank is<br />
killed, it will be demoralizing and traumatic,<br />
especially for his daughter, who is with<br />
him. However, if Frank is not killed, he will<br />
most likely become a zombie and attack the<br />
remaining survivors.<br />
Ana’s character is humanizing for the<br />
audience because she reminds us of this<br />
ethical dilemma. A professional nurse<br />
has specific nursing values and ethical<br />
responsibilities to uphold. Of the eight<br />
values outlined in the Code of Ethics<br />
for Registered Nurses, Ana maintains<br />
four values that pertain specifically to<br />
this situation: 1) Safe, Compassionate,<br />
Competent Ethical Care, 2) Informed<br />
Decision Making, 3) Preserving Dignity and<br />
4) Promoting Justice. 4 She provides safe,<br />
compassionate, competent and ethical care<br />
for all of the survivors—to the best of her<br />
ability—within her limited environment.<br />
She discusses the ethical dilemma regarding<br />
Frank’s zombie bite with Frank and the<br />
group, thereby recognizing, respecting and<br />
promoting Frank’s right to be informed<br />
and to make a decision. She recognizes<br />
and respects Frank’s intrinsic worth by<br />
reminding the group that he has a daughter<br />
who cares for him. And lastly, Ana upholds<br />
principles of justice by safeguarding human<br />
rights as much as possible within the given<br />
situation, and promotes the public good for<br />
the group of survivors.<br />
autonomous Role of the nurse<br />
At the very beginning of the film, the<br />
audience is able to see what life is like for<br />
Ana before the chaotic zombie infection<br />
spreads. Ana interacts with a physician,<br />
another health care professional, in the<br />
emergency department. The physician<br />
dismisses Ana’s statement that it is the end<br />
of her shift and asks her to find a patient<br />
who has been admitted to the hospital.<br />
Here, the audience briefly witnesses the<br />
heroine in a subservient role in relation to<br />
the physician.<br />
This situation relates to the autonomy of the<br />
nursing profession. In this particular scene<br />
in the film, Ana does not embody the role<br />
of an autonomous professional. However,<br />
in clinical settings, nurses do not report to<br />
physicians, as the film portrays. 1 Nurses<br />
report to their supervisor who is usually a<br />
nurse, not a doctor. This misperception is<br />
an ongoing challenge within popular media<br />
sources. As previously discussed, nurses<br />
have their own code of ethics as outlined by<br />
the CNA. 4 Nursing is a distinct autonomous<br />
profession that is regulated and governed<br />
by experienced nurses, many of whom hold<br />
graduate level degrees. 6<br />
In order to address the discrepancy between<br />
the media perception of the autonomy of<br />
nursing and the truly autonomous nature<br />
of the profession, nurses must advocate for<br />
their profession and effectively communicate<br />
with members of the media to demonstrate<br />
accurate representations, and for pride in<br />
the profession of nursing. 2 The image and<br />
role of the nurse will continue to evolve<br />
in a positive direction when practicing<br />
professional nurses are actively involved<br />
in a relationship with the media. McNally<br />
suggests that these efforts should begin at<br />
an undergraduate level. 6<br />
As the film progresses, the audience begins<br />
to see that Ana is capable of practicing<br />
autonomously, and that she is most certainly<br />
not subservient to other characters. Rather,<br />
Ana carries a leadership role in many<br />
instances throughout the film, such as<br />
independently setting up a triage center<br />
for those who are injured and encouraging<br />
group cohesion to battle attacking zombies.<br />
Ana’s autonomous role begins in the film<br />
once the zombie catastrophe begins.<br />
Context of the Film<br />
Overall, the film Dawn of the Dead presents<br />
a positive image of the nurse. I do, however,<br />
question the context in which this positive<br />
image is portrayed. This popular media<br />
portrayal of the nurse differs from what is<br />
found in the professional nursing literature,<br />
as the nurse in this film is acting within<br />
a fictional world overrun by zombies. Is<br />

the profession of nursing limited to the<br />
constraints of an apocalyptic setting?<br />
This catastrophic zombie world is<br />
comparable to the media representation<br />
of nurses during wartime, which presents<br />
nurses as “pure, brave, maternal, and free<br />
of the corruptive taint of war.” 2 Stanley<br />
examines how nurses are portrayed in<br />
feature films and identifies many themes<br />
in his data. In analyzing presentations<br />
of nursing throughout history, Stanley<br />
identifies themes such as: romance; heroism;<br />
self-sacrifice; intelligence; nurses as sex<br />
objects; nurses as strong women; nurses<br />
as victims; and the dark nurse. 3 Certain<br />
qualities, such as self-sacrifice, heroism,<br />
and the intelligent nurse, are predominant<br />
during difficult times in history, such as war<br />
and depression.<br />
In an earlier study, Kalisch and Kalisch<br />
examined English-language films released<br />
between 1930 and 1979. 7 Positive images<br />
and stereotypes of the nurse role are<br />
identified during World War I, the Great<br />
Depression, and World War II. In Dawn of<br />
30<br />
the Dead, the nurse is also a strong, positive<br />
character who demonstrates professional<br />
nursing during a similar global chaotic<br />
event. Interestingly, Kalisch and Kalisch note<br />
that once war is over, the representation<br />
of the nurse in the media reverts to that of<br />
a woman in her “rightful” place. That is,<br />
according to Kalisch and Kalisch, the nurse<br />
returns to “tending to children in their<br />
happy homes in the suburbs.” 7<br />
Despite the positive depiction of the nursing<br />
role in Dawn of the Dead, it is possible that<br />
nursing roles are only presented positively<br />
in the media when the nurse is working<br />
in the context of widespread disaster. The<br />
film Dawn of the Dead takes place in a<br />
chaotic environment, creating a challenge<br />
for the audience to view the value of the<br />
role of the professional nurse within a<br />
conventional world.<br />

ABSTRACT<br />
This article chronicles the career of one<br />
of the most important Canadian plastic<br />
surgeons of the twentieth century, Albert<br />
Ross Tilley. Tilley is best known for his<br />
innovations in burn management during<br />
World War II (WWII), and his treatment of a<br />
group of burn patients known affectionately<br />
as the Guinea Pig Club. In addition to the<br />
superb surgical skills he applied to the<br />
physical wounds of his patients, Tilley was<br />
also a pioneer of caring for the emotional<br />
and psychological afflictions suffered<br />
by many airmen of WWII. As one of the<br />
founding fathers of the Canadian Society<br />
of Plastic Surgeons, Tilley’s work was<br />
instrumental in establishing the specialty,<br />
and ensured its prominence for years to<br />
come. Serving in the capacity of leader,<br />
educator, and innovator, Tilley remains one<br />
of Canada’s most decorated physicians,<br />
and his contributions to the medical field<br />
continue to benefit patient care to this day.<br />

INTRODUCTION<br />
As one of the first plastic surgeons in<br />
Canada, Dr. Albert Ross Tilley helped shape<br />
the discipline’s foundation (Figure 1). Tilley<br />
influenced the trajectory of a burgeoning<br />
specialty, as well as a generation of young<br />
practitioners who aspired to become part<br />
of the profession. Tilley was an innovator of<br />
burn management in the wake of a war that<br />
threatened to incinerate all those engaged<br />
in battle, and the healer of an affliction that<br />
society was ill-equipped to handle. The<br />
medicine Tilley dispensed indelibly altered<br />
the landscape of patient care forever.<br />
Tilley’s Background<br />
Albert Ross Tilley was born in Bowmanville,<br />
Ontario, on November 24, 1904. 1 Tilley’s<br />
interest in medicine was piqued at an early<br />
age, as he had the privilege of accompanying<br />
his father, a general practitioner, while he<br />
rounded on patients. Tilley graduated from<br />
the University of Toronto medical school in<br />
1929 as a silver medalist. 2 Following medical<br />
school, he traveled extensively for five years,<br />
studying surgery at the Toronto Western<br />
Hospital in Ontario, the Roosevelt and<br />
Bellevue Hospitals in New York, The Royal<br />
Infirmary of Edinburgh in Scotland, and<br />
with the renowned pathologist Sternberg in<br />
Vienna. 2 By 1935, Tilley was ready to open a<br />
private practice working at the Wellesley and<br />
Toronto Western Hospitals.<br />
In the same year, Tilley joined the No. 400<br />
City of Toronto Squadron of the Royal<br />
Canadian Air Force (RCAF) as a medical<br />
officer, and began what would turn out to be<br />
the most important training of his career. 2<br />
Dr. E. Fulton Risdon, a protégée of Sir<br />
Harold Gillies, and widely regarded as the<br />
father of modern plastic surgery in Canada,<br />
would guide Tilley’s focused training in<br />
plastic surgery. At the time, Dr. Risdon was<br />

Figure 1. Dr. Albert Ross Tilley.<br />
one of only three other plastic surgeons<br />
in Canada, and Tilley became the fourth<br />
upon the completion of his training just<br />
prior to the outbreak of World War II. 3 Tilley<br />
was called up to active service in 1939, and<br />
by 1940 he found himself a commanding<br />
officer and C Surgeon at Trenton Memorial<br />
Hospital. 3 A year later, he was appointed<br />
principal medical officer at the RCAF<br />
headquarters in London, England.<br />
Shortly after arriving in London, Tilley<br />
received a life-altering invitation, the<br />
acceptance of which would set into motion<br />
a chain of events that literally changed<br />
the faces of hundreds of airmen burned in<br />
WWII. Equipped with his newly honed skills<br />
in plastic surgery, Dr. Tilley traveled to the<br />
Queen Victoria Hospital in East Grinstead,<br />
Sussex in January of 1942. 1 There he was<br />
charged with the task of treating the most<br />
difficult burn injuries wrought from the pyre<br />
of war.<br />
Fates Worse Than death: Burn<br />
Casualties Of WWII<br />
History has frequently demonstrated that<br />
factors of circumstance set the stage for<br />
greatness, and one particular confluence of<br />
events allowed Tilley to produce outstanding<br />
innovations in the field of plastic surgery.<br />
One such event that would push Tilley’s<br />
skills to their very limit was the nature of the<br />
burn casualties of WWII. It is reasonable to<br />
assume that being caught in the crosshairs<br />
of a Nazi pilot was the worst nightmare of<br />
every Allied airman, but this was not the<br />
case. The entity that struck unadulterated<br />
fear into the hearts of the RCAF airmen<br />
was fire. Referred to by nicknames like<br />
“orange death”, the threat of burning alive<br />
was an unrelenting terror, and many pilots<br />
openly admitted that gravity or a bullet was<br />
a welcome alternative. 4 On Allied aircraft,<br />
whether Spitfire or Hurricane, the vector<br />
carrying the combustible arch nemesis of<br />
airmen was the fuel tank. 5<br />
During the interwar period, the Royal Air<br />
Force (RAF) conceived of new and ambitious<br />
strategies for air warfare of the future.<br />
Unfortunately, the demands of this strategy<br />
pitted fuel tank safety against parameters<br />
of performance. In order to produce planes<br />
that could out-fly and out-shoot the<br />
competition, drastic changes in aeronautical<br />
design were necessary, including upgrading<br />
the 87-octane fuel used in the Great War,<br />
to the more combustible 100-octane fuel. 7<br />
Furthermore, to achieve the highly soughtafter<br />
rapid rate of ascent, fuel tanks now<br />
had to be positioned directly below and in<br />
front of the cockpit. In essence, the pilot<br />
would find himself sitting on about 85<br />
gallons of fuel in the Spitfire, and 30 gallons<br />
of fuel in the Hurricane. 5 The problem<br />
with implementing previously used tank<br />
protection systems of rubber and metal<br />
encasements was that the materials added<br />
nearly 50 kg to the plane’s weight. This<br />
burden cut the maximum range of fighter<br />
planes by nearly 20%, and was a sacrifice<br />
in performance that top officials of the<br />
RAF were unwilling to accept. 4 Ultimately,<br />
strategy took priority over safety, and<br />
pilots were left to rely on their tactical skill<br />
rather than novel engineering to avoid the<br />
potential inferno sloshing around below<br />
them. To the dismay of hundreds of airmen,<br />
this performance requirement, though<br />
highly refined, would not prove enough,<br />
and many sustained burns rendering<br />
them unrecognizable.<br />
It is estimated that between 1940-1945,<br />
22,000 soldiers burned to death, and 4,500<br />
burn victims were recovered from crashes,<br />
with 60-80% of those rescued sustaining<br />
burns to their hands and face. 8 This scale<br />
of burn casualties had never before been<br />
witnessed, and was not predicted by<br />
Allied strategists. A certain pattern of burn<br />
injury presented so frequently to hospitals<br />
that it was given its own designation.<br />
“Airman’s Burn” was described in numerous<br />
wartime medical texts as ‘a burn of almost<br />
unwavering characteristics due to the<br />
sudden exposure of unprotected parts of the<br />
body to intense dry heat or flame, as though<br />
the patient were thrust into a furnace for a<br />
few seconds and withdrawn.’ The product of<br />
this process was ‘deep, searing burns, usually<br />
of third degree to areas of tremendous<br />
functional importance -- the hands and<br />
eyelids in particular.’ 9 The position of the<br />
fuel tank often resulted in its contents<br />
exploding in the face of the pilot, which<br />
accounts for the characteristic facial burns<br />
sustained. In addition to the hands and face,<br />
airmen commonly suffered burns to their<br />
wrists, neck, thighs, and scalp. 10<br />
The motivation of the RAF and RCAF to<br />
commit whatever resources necessary to<br />
ensure the best treatment possible for its<br />
burned airmen was two-fold. Firstly, these<br />
young men had volunteered to fight in the<br />
service of protecting their country, and the<br />
indebted nation demanded they receive care<br />
of the highest quality. Secondly, pilots were<br />
an invaluable resource in the war campaign,<br />
especially during the Battle of Britain.<br />
During the autumn of 1940, experienced<br />
pilots proved a commodity more critical to<br />
victory than steel or oil. 6 Burn injuries served<br />
to remove airmen from combat for weeks<br />
to months at a time, and therefore, the RAF<br />
needed to rehabilitate its most valuable<br />
resource as quickly as possible under the<br />
threat of an air campaign failure. Luckily for<br />
the multitude of victims, there were men<br />
like Tilley who were willing and able to<br />
set themselves to the task of rehabilitating<br />
these heroes.<br />
Tough as Leather: Burn<br />
Management Before WWII<br />
Shortly after arriving at East Grinstead, it<br />
became apparent to Tilley that the increasing<br />

number of Canadian burn casualties<br />
flooding the hospital would need their own<br />
ward. Under Tilley’s planning and leadership<br />
as the newly appointed chief surgeon<br />
and commanding officer, Royal Canadian<br />
Engineers prepared to erect a 50-bed wing<br />
that would cost $80,000 and take a year to<br />
build. 2-4 Upon its completion in 1944, the<br />
Canadian wing had a staff of over 50 people<br />
including orderlies, specialist nurses, and<br />
clerks (Figure 2).<br />
For decades before WWII, patients with<br />
severe burns were deemed terminal and the<br />
standard of care consisted of administering<br />
minute amounts of saline, a gargantuan<br />
dose of morphine, and orders for the<br />
patient to return home so they could be<br />
surrounded by their loved ones as death<br />
swiftly followed. 11 Burn patients were<br />
scarcely encountered in teaching hospitals<br />
because their case was viewed as hopeless<br />
and admission rarely occurred. The reason<br />
that major burns rapidly killed nearly<br />
everyone sustaining them was shock, and<br />
the inability of the medical profession to<br />
administer effective treatment to halt its<br />
progression. 8 Severe burns would initiate<br />
a chain reaction of events beginning with<br />
massive fluid loss from the wound, followed<br />
by shock and the successive failure of<br />
multiple organ systems until the patient was<br />
32<br />
no longer able to cling to life. If by some<br />
divine intervention the patient persevered<br />
through the shock, the next hurdle to their<br />
recovery was infection. With odds stacked so<br />
highly against recovery from severe burns,<br />
the treatments that developed were largely<br />
chemical interventions geared towards<br />
minor burns, with surgical involvement a<br />
rare occurrence. 10 Breakthroughs in treating<br />
shock changed everything.<br />
The 1920s saw physicians tinkering with the<br />
idea of fluid resuscitation, but out of fear of<br />
unknown adverse effects, they never dared<br />
to give fluid in the amounts necessary to<br />
stem the tide of shock. 8 It was not until the<br />
1930s that saline and plasma transfusions<br />
were gradually being administered in<br />
ever-increasing volumes. Eventually, the<br />
treatment of shock had evolved to such<br />
an extent that the majority of severe burns<br />
historically viewed as death sentences no<br />
longer produced corpses for coffins, but<br />
extremely complicated patients requiring<br />
specialized, multifaceted care. 4 The advances<br />
in shock therapy inadvertently created a new<br />
patient population that needed treatment<br />
desperately. The physicians of the day did all<br />
they could using the tools available to them.<br />
The results, however, proved unacceptable<br />
to physicians like Tilley.<br />
When the first wave of severely burned<br />
airmen presented to hospital, the major<br />
treatment method centered around<br />
coagulation. A coagulating agent would<br />
be applied to the burn, which caused a<br />
tough hide of scab-like tissue to encase<br />
the wound. 10 This functioned as a physical<br />
dressing of sorts, and was thought<br />
advantageous by many physicians in its<br />
ability to protect the wound, prevent lifethreatening<br />
fluid loss, and guard against<br />
sepsis. 8 The coagulant that was administered<br />
nearly universally was tannic acid, 12 the<br />
very same substance used in the leather<br />
industry to stiffen hides. Metal tubes of<br />
tannic acid were so widely distributed, that<br />
at the outset of the war, they could be found<br />
in almost every ER, medic bag, and first-aid<br />
kit in Allied territory. In theory, coagulation<br />
therapy served both as immediate firstaid,<br />
as well as a long-term treatment<br />
that remained in place until new tissue<br />
had grown underneath, after which the<br />
coagulum could be removed. 13<br />
The reality of treating airmen’s burns with<br />
tannic acid turned out to be so disastrous<br />
that it prompted one of Tilley’s mentors at<br />
the Queen Victoria Hospital, the great Sir<br />
Archibald McIndoe, to undertake a crusade<br />
against its continued use. The problems with<br />
treating airmen’s burn with coagulation<br />
University of <strong>Alberta</strong> Health Sciences Journal • April 2012 • Volume 7 • Issue 1
therapy were numerous. Tannic acid applied<br />
to burns of the hands resulted in stiffness<br />
to the point of complete immobility. 14<br />
In addition to stiffness, the thick hide of<br />
coagulated tissue exacerbated edema, and<br />
constricted an already diminished circulation.<br />
This compression of blood flow in the hands<br />
frequently resulted in ischemia, necrosis,<br />
and the loss of fingers. 14 The black eschar<br />
produced also made it very difficult for the<br />
medical staff to detect infections, which often<br />
went unrecognized until the indicative aroma<br />
wafted into the nostrils of patient and staff.<br />
With the goal of avoiding septicemia, the<br />
coagulum was then ripped from the wound<br />
so antiseptic agents could be administered,<br />
but this commonly proved ineffective and<br />
agonizingly painful for the patient. 10<br />
Results of coagulants applied to burns of the<br />
face were equally distressing. Gentian violet<br />
was used for facial burns due to the belief<br />
that it was more ‘delicate’ than tannic acid. 15<br />
Despite its purported virtue, gentian violet<br />
left facial tissue rigid, and eyelids so taut that<br />
the patient often suffered corneal scratches<br />
or ulceration from being unable to blink. 15 If<br />
lucky enough to avoid irrevocable blindness<br />
during the gentian treatments, the patient<br />
then had to worry about the subsequent<br />
scarring that often everted the eyelids.<br />
Setting aside their immediate harm, the<br />
long-term hindrance posed by coagulation<br />
therapy was that it completely obliterated<br />
viable grafting surfaces. Once the coagulum<br />
was removed, its place was taken by thick<br />
spindles of keloid scarring, the likes of<br />
which vaporized hope for any degree of<br />
reconstruction. 15<br />
Fortunately for the hundreds of patients<br />
who suffered burns of the hands and<br />
face, McIndoe was able to persuade the<br />
majority of his colleagues, and the scientific<br />
community at large, that the heinous results<br />
of tannic acid justified the banishment of its<br />
use across Europe. 16<br />
Figure 3. Saline bath at Queen Victoria Hospital.<br />
Pulled From The Furnace: Tilley’s<br />
approach To Burn Management<br />
With coagulation therapy for third-degree<br />
burns of the hands and face effectively<br />
banned by the late 1940s, thanks to the<br />
advocacy of McIndoe and Tilley, the<br />
challenge of implementing an efficacious<br />
treatment regimen for severe burns loomed<br />
over the wards of East Grinstead. The<br />
approach cultivated by McIndoe and Tilley<br />
at the Queen Victoria Hospital, which served<br />
as the prototype for burn management and<br />
was duplicated at centers across Europe,<br />
consisted of three vital components. 4 In<br />
order to preserve surfaces viable for grafting,<br />
atraumatic dressings were essential. The<br />
form of dressing most commonly used<br />
consisted of a single layer of Tulle Gras, a<br />
non-adhesive bandage composed of fabric<br />
with variable proportions of paraffin and oil<br />
impregnating the material, placed directly<br />
on the surface of the wound, followed by<br />
a sterile saline compress over top. 14 The<br />
benefits of this method became apparent<br />
anytime staff needed to remove the<br />
dressings to clean the wound, or examine<br />
it for signs of infection; the Tulle Gras could<br />
be changed easily without inciting any<br />
additional trauma at the burn site.<br />
The second pillar of burn management<br />
Tilley utilized was the saline bath (Figure 3).<br />
Ablution was viewed as a critical method in<br />
maintaining clean, healthy wounds as well<br />
as being instrumental in the granulation<br />
process. 14 In addition to fostering a viable<br />
grafting surface, saline baths also allowed<br />
patients to keep their wounds flexible. This<br />
was especially important for burned hands,<br />
which were much more mobile under water<br />
and proved quite favorable for circulation<br />
and the salvaging of the greatest proportion<br />
of digits possible. 16 Patients under Tilley’s<br />
care would soak for an hour in tubs of<br />
saline, two to three times daily, during which<br />
Figure 4. Surgery at the Queen<br />
Victoria Hospital.<br />
time, dressings would seamlessly float off<br />
the burn site and save the patient from the<br />
potential agony of removing them under<br />
dry conditions. 10<br />
To achieve a truly successful treatment<br />
regimen, Tilley’s management of burns also<br />
had to neutralize infections. “Sulphanamide<br />
dusting” was one strategy employed, in<br />
which a powder form of sulphanamide, an<br />
antibiotic, was gently sprinkled over the<br />
surfaces of burns. 14 For burns of the hand,<br />
plastic bags filled with powder encasing the<br />
injured limb were used. 14 Tilley also noticed<br />
that the wool blankets used in hospitals<br />
harbored and transmitted infections to<br />
scores of patients across Europe, therefore,<br />
he had them exchanged with layered linens.<br />
One of the more ‘radical innovations’<br />
employed at Queen Victoria Hospital was<br />
to ensure physical separation of the burn<br />
unit from other wards of the hospital, which<br />
broke with the convention of burn patients<br />
interspersed throughout various wards. 4 This<br />
served to cut the rampant infection rates<br />
produced by cross-contamination between<br />
patient groups that had plagued hospitals in<br />
the past. Patients at highest risk were those<br />
with burn wounds and jaw injuries, and they<br />
were housed in special isolation units.<br />
With the sulphanamide-tulle gras-saline<br />
sequence producing patients whose<br />
burns remained conducive to subsequent<br />
reconstructive therapy, Tilley now set himself<br />
to the task of restoring the hands and faces<br />
his patients had lost (Figure 4). One of<br />
Tilley’s first objectives was to reconstruct<br />
the ears of his patients: “without them” he<br />
asked, “how could a man hold his glasses<br />
on?” 3 Most men would need between<br />
between ten and fifty operations, requiring<br />
them to be in and out of the hospital for at<br />
least three years. It was customary to plan<br />
eight surgeries per year, alternating three<br />

to four weeks in hospital, with two to three<br />
week breaks outside. 10<br />
Generally, acromiothoracic flaps were<br />
utilized for deep unilateral burns, but in<br />
cases where adequate free grafts could be<br />
produced, patients were treated in this<br />
way entirely. 8 During his tenure at Queen<br />
Victoria hospital, Tilley would replace<br />
countless noses, reform a multitude of ears<br />
and eyelids, and re-establish facial features<br />
for hundreds of men; all of this with the<br />
objective of giving his patients the chance<br />
to return to a normal state of existence. But<br />
Tilley’s operative virtuosity was not all he<br />
offered his patients….<br />
a Scalpel, a Guinea Pig, and a<br />
Tender Hand: Tilley’s approach<br />
To The Patient Relationship<br />
By 1944, the Canadian wing at Queen<br />
Victoria Hospital opened, and Tilley was<br />
promoted to the rank of Group Captain.<br />
In June of the same year, Tilley found<br />
himself standing in front of King George<br />
VI at Buckingham Palace with the Order of<br />
the British Empire being bestowed upon<br />
him. 1 This prestigious award was fitting<br />
recognition of Tilley’s success in Britain;<br />
along with the work of McIndoe and the<br />
hospital staff, they had become “the most<br />
formidable and effective response to burn<br />
injuries, anywhere in the world.” 4<br />
The work at Queen Victoria hospital was so<br />
groundbreaking that it brought one patient<br />
to remark in jest, “we’re nothing but a<br />
bunch of damn guinea pigs!” Subsequently,<br />
the Guinea Pig Club was formed in 1941,<br />
by a group of airmen who had suffered<br />
burn injuries in the war and were treated<br />
at the Queen Victoria Hospital. Consisting<br />
of nearly 650 members of a dozen different<br />
nationalities, the club was one of the first<br />
support groups in medical history. 17 The<br />
Figure 5. Tilley poses for a photo symbolizing the<br />
care he gave to his real patients, the Guinea Pigs.<br />
34<br />
camaraderie and sense of belonging fostered<br />
by the club has been acknowledged by<br />
many historians as instrumental in the<br />
therapeutic success ultimately achieved<br />
at East Grinstead. 4 The Guinea Pig Club<br />
helped shield patients from suffering their<br />
disfigurement in isolation, and gave its<br />
members the strength to venture out into<br />
the world, and walk the streets wearing their<br />
wounds as testaments of their sacrifice. Tilley<br />
served as president of the Canadian branch<br />
of the Guinea Pig Club, and continued to<br />
operate on over two hundred of its members<br />
for the next forty years (Figure 5). 3<br />
Tilley dedicated a tremendous amount of<br />
personal attention to the emotional and<br />
psychological condition of his patients. After<br />
operating all day and into the evening, Tilley<br />
would rest briefly in his living quarters only<br />
to make his way back to the hospital at 23:00<br />
h to check how his patients were faring<br />
after their surgeries. 4 In a medical landscape<br />
dominated by rampant paternalism,<br />
Tilley was a trailblazing pioneer of patient<br />
empowerment who went to great lengths<br />
to educate his patients about every aspect<br />
of their care, every nuance of their surgeries,<br />
and the intricate details of what they could<br />
expect during recovery. 18 Where many<br />
surgeons of the day saw their involvement<br />
in patient care beginning and ending in the<br />
operating room, Tilley was a fierce proponent<br />
of the importance of a patient’s psychological<br />
wellbeing in their overall rehabilitation. In his<br />
care of the Guinea Pigs, Tilley transcended<br />
the customary duties of a physician and rose<br />
to become a shining light that illuminated a<br />
comprehensive path to recovery. 18<br />
For decades after the war, Guinea Pigs<br />
from across the world would come together<br />
for an annual celebration where one of<br />
their toasts was always to the care they<br />
received from Tilley. Out of gratitude for<br />
Tilley’s commitment to them, the Guinea<br />
Pig Club funded a bronze bust of their<br />
beloved physician, which was installed in<br />
the Canadian wing of the Queen Victoria<br />
Hospital. The sculpture commemorates the<br />
man whose tender hand pulled them from<br />
the furnace, and allowed them to transcend<br />
what had once been thought of as a fate<br />
worse than death. 2<br />
no Sign Of Slowing down:<br />
Tilley’s Life after The War<br />
Upon his return from Britain in 1945, Tilley<br />
became a consulting physician at Christie<br />
Street Hospital and Toronto Wellesley<br />
Hospital. For several years between 1949-<br />
1965, Tilley also spent three days every<br />
month in Kingston where he worked as a<br />
staff physician at the Hotel Dieu, Kingston<br />
General, and Kingston Military Hospitals. 2<br />
As one of only ten other plastic surgeons<br />
practicing in Canada after the war ended,<br />
Tilley was extremely busy laying the<br />
framework for the future of his specialty.<br />
His colleagues viewed Tilley as a physician<br />
capable of breaking new ground. In July of<br />
1942, he led the first all-Canadian plastic<br />
surgery operation, and a few years later as<br />
an assistant professor at Queens University,<br />
he became the first to offer formal accredited<br />
courses in the specialty. 2 Tilley also invented<br />
several surgical instruments, such as an<br />
ingenious hand splint, and was the first to<br />
19, 20<br />
design the tube pedicle flap.<br />
Tilley was one of the twelve founding<br />
fathers of the Canadian Society of Plastic<br />
Surgeons in 1947. At its second annual<br />
meeting on June 2, 1948, the society’s<br />
members empowered Tilley to draft a fee<br />
schedule for the operations performed most<br />
commonly by plastic surgeons. 20 Appointed<br />
vice-president in 1953, and then president<br />
in 1954, Tilley’s leadership of The Canadian<br />
Society of Plastic Surgeons helped establish<br />
the profession in Canada and paved the way<br />
for the exponential growth and prosperity it<br />
would experience in subsequent years. 20<br />
As his specialty flourished across the<br />
country, Tilley continued to infuse his<br />
discipline with respect and integrity as<br />
he campaigned for years to develop burn<br />
treatment facilities in Ontario. In 1984, his<br />
vision came to fruition and the Ross Tilley<br />
Burn Centre opened at Wellesley Hospital. 21<br />
Only three years after becoming the first<br />
plastic surgeon to be appointed a member<br />
of the Order of Canada, Tilley also assumed<br />
the role of Founder and Director of the first<br />
19, 21<br />
adult burn centre in Canada.<br />
Even after retiring from practice at Wellesley<br />
and Sunnybrook hospitals in 1981,<br />
Tilley continue to be recognized for his<br />
outstanding career. An elementary school in<br />
his hometown of Bowmanville was named<br />
in his honour, and he was inducted into<br />
Canada’s Aviation Hall of Fame in 2006. 1,3<br />
After dedicating much of his 84 years of life<br />
to his patients, Albert Ross Tilley passed<br />
away on April 19, 1988. 21<br />
CONCLUSION<br />
The distinguished and illustrious career<br />
of Albert Ross Tilley exemplifies many of<br />
the qualities sought after by physicians<br />
today. As a surgeon, he is remembered<br />
for his meticulous technical skill, sound<br />
judgment, and tireless work ethic. He was<br />
a leader, innovator, and educator whose<br />
efforts sculpted an immature specialty into<br />
a refined profession. As a man, Tilley’s virtue<br />
and character stood beyond reproach, and<br />
University of <strong>Alberta</strong> Health Sciences Journal • April 2012 • Volume 7 • Issue 1
he was acknowledged with Canada and<br />
Britain’s highest honours.<br />
The most valuable lesson that Tilley’s legacy<br />
offers this generation of medical students<br />
and physicians, can be gleaned from his<br />
first encounters at East Grinstead. Standing<br />
at the bedside of his patient and assessing<br />
the medicines he had at his disposal, Tilley<br />
shook his head and resolved to do better;<br />
he refused to surrender to the limitations<br />
dictated by existing medical practice.<br />
Tilley tossed aside the contemporaneous<br />
treatment of coagulation therapy, the merits<br />
of which were being espoused by experts<br />
in the field. With a steadfast conviction<br />
that his patients deserved a higher level<br />
of treatment, Tilley worked tirelessly with<br />
McIndoe and hospital staff to produce<br />
a revolutionary regimen that ultimately<br />
saved the hands, faces, and livelihoods of<br />
hundreds of men. Tilley’s actions at Queen<br />
Victoria Hospital serve as a reminder<br />
to modern day practitioners of their<br />
responsibility to address deficient aspects<br />
of patient care, and to innovate, when<br />
necessary, in order to provide patients with<br />
the best possible medicine.<br />

THE HOUSE OF GOD<br />
By Samuel Shem<br />
New York, NY, Dell, 2003 (first published:<br />
New York, NY, Richard Marek, 1978).<br />
ISBN 978-0385337380<br />
Medical training has changed a great deal<br />
over the past thirty years, along with the<br />
way medicine is practiced in general. This<br />
is interesting to consider in the context<br />
of the American medical system, which<br />
has the dubious honor of boasting the<br />
most sophisticated yet unevenly accessible<br />
medical system. In light of this, it is perhaps<br />
not surprising that at some point along<br />
the way voices of dissent would emerge,<br />
even from within the ranks of the medical<br />
establishment itself.<br />
Samuel Shem’s (the pen name of Dr.<br />
Stephen Bergman) House of God was<br />
first published in 1978, as a semiautobiographical<br />
account of Dr. Roy Basch’s<br />
internship year in the eponymous hospital.<br />
With the ripples of the civil rights movement<br />
still being felt, and the Watergate scandal<br />
showcasing the moral ambiguity of the<br />
nation’s highest offices, Shem’s honest<br />
and at times disturbing portrayal of one<br />
of America’s most prestigious teaching<br />
hospitals was a timely contribution to the<br />
changing social and political landscape.<br />
Now, over three decades later, even a<br />
sophomore medical student on the brink<br />
of entering clerkship may be struck by Dr.<br />
Bergman’s candid observations concerning<br />
the challenges of medical education. This<br />
book offers a compelling caricature of some<br />

general themes that many facing a career in<br />
a medical discipline are likely to encounter:<br />
from management of chronically ill patients,<br />
to acrimonious relationships (both personal<br />
and professional) with fellow colleagues.<br />
If you have not yet read the House of God,<br />
your first thought may be whether this<br />
fictionalized account from the 1970s has<br />
any relevance to the plight of today’s<br />
medical trainee. The short answer, which<br />
becomes obvious even after the first few<br />
chapters describing Roy’s arrival to the<br />
House, is a resounding yes. There are of<br />
course elements of the book that will be<br />
difficult to reconcile with the reality of<br />
resident life thirty years later: The text is<br />
littered with outdated medical references,<br />
and is punctuated throughout with a<br />
tone of arcane paternalism that would be<br />
unacceptable by today’s standards. These<br />
anachronisms, however, beyond reminding<br />
us that the book is situated in another era<br />
altogether, are also important for another<br />
reason. They allow today’s reader to<br />
appreciate those egregious aspects of the<br />
American healthcare system of the 1970’s<br />
for their comic relief, and serve to reinforce<br />
many of the book’s themes. Furthermore,<br />
the fact that many of its themes still apply<br />
today only reinforces Bergman’s talent and<br />
perspicacity.<br />
By introducing us to the morbid humour<br />
and unsavory behaviour which Roy and<br />
his colleagues would often invoke to make<br />
sense of the difficult situations in which<br />
they found themselves, Bergman reveals the<br />
importance of having a stress outlet. We see<br />
this evinced through different characters<br />
in the book. The narcissistic Pinkus<br />
comes to mind, with his utter emotional<br />
detachment from his ICU patients, coupled<br />
with his nearly monastic devotion to his<br />
own running routine and sculpted calves.<br />
The lack of an appropriate outlet is also<br />
mirrored in Roy’s steadily mounting inner<br />
turmoil as his internship year progresses.<br />
Our protagonist’s ongoing awareness of the<br />
macabre, often futile nature of his various<br />
coping strategies gives the narrative further<br />
36<br />
depth and tension, and keeps the reader<br />
wondering just how much more Roy can<br />
take.<br />
Bergman’s development of secondary<br />
characters to further explore the<br />
complexities of internship is nicely<br />
accomplished. Notable among these is Barry,<br />
his clinical psychologist girlfriend, whose<br />
unwavering presence serves as a moral<br />
counterweight to his frenetic mood swings<br />
and constant disequilibrium. Indeed, Barry’s<br />
views often come across as a reminder of<br />
the humanity and basic conscientiousness<br />
that Roy begins the year with, but gradually<br />
loses, as he sinks further into the soulsucking<br />
drudgery of ward-based medicine at<br />
the House.<br />
Roy’s in-house sanity is provided by the<br />
enigmatic and brilliant senior resident,<br />
known only as the ‘fat man’, whose<br />
sacrosanct “Laws” of the House come to<br />
form the basis of most of Roy’s clinical<br />
decisions, often in flagrant disregard to<br />
everything his previous medical education<br />
has taught him. While some may seem<br />
trite at first (e.g. law #4 “THE PATIENT IS<br />
THE ONE WITH THE DISEASE”), others,<br />
such as law #13, come to signify one of the<br />
book’s pervasive themes: “THE DELIVERY<br />
OF GOOD MEDICAL CARE IS TO DO AS<br />
MUCH NOTHING AS POSSIBLE”. This<br />
statement may seem fairly counterintuitive<br />
at first, but gains considerable traction<br />
when considered in the context of Roy’s<br />
misadventures at the House.<br />
The House is also a rich resource on<br />
terminology for any new initiate to the<br />
medical sphere, and worth the read from<br />
that perspective alone. Here we find the<br />
origins of terms that many of us may be<br />
familiar with already, such as GOMER (‘get<br />
out of my emergency room’); BUFF (the<br />
careful art of making a chart look good,<br />
which often treads the fine line between<br />
perjury and embellishment); and TURF<br />
(using any excuse possible to hand off<br />
care of your patient to another service or<br />
department). While such catchwords may<br />
not be used very frequently today, the spirit<br />
of these terms almost certainly persists, as<br />
many with first-hand clinical experience will<br />
recognize.<br />
Dr. Bergman also addresses the notion of<br />
hierarchy throughout the book, and how<br />
embedded it is at all levels of training and<br />
administration. While his criticisms are<br />
often oblique and bordering on subversive<br />
(often at the expense of one of Roy’s senior<br />
colleagues or House staff), they are also<br />
poignant and hilarious. A particularly<br />
memorable image is that of the Leggo, Roy’s<br />
uptight and oblivious superior staff member,<br />
with his stethoscope in its default position<br />
winding down into his trousers (which Roy/<br />
Bergman playfully mocks throughout the<br />
book). Interestingly, Bergman’s depiction<br />
allows the reader some first-hand insight<br />
into both the folly and utility of this<br />
entrenched system, the relics of which are<br />
still present today.<br />
At the end of the day, The House of God<br />
is a pleasant and engrossing read, and<br />
there is much to be gained in reflecting on<br />
Roy’s tumultuous foray into the world of<br />
hospital-based medicine. The prescience of<br />
this book and the ‘Laws of the House’ are<br />
worth noting today as we find ourselves<br />
in the midst of health care system that is<br />
underfunded, short-staffed, and overused.<br />
In critiquing the medical system in which<br />
we train and work (albeit through the lens<br />
of a 1970s intern), The House of God forces<br />
the reader to consider just how sustainable<br />
our current practices are. This message is<br />
especially pertinent in the context of our<br />
ageing population, since many of our current<br />
practices in medicine were founded in Roy’s<br />
era of relative resource abundance.<br />
