W. Kang, Y. J. Kim, K.-W. Hong, S. I. Kim, Y. R. Kim The catholic University of Korea, Seoul, Korea, Republic of Background: Abscess of the psoas muscle is a rare disease. Because of nonspecific presentation, it is difficult to diagnosis. There is a wide spectrum in etiology, time to diagnosis, and therapeutic options. This study is to describe the etiology, clinical features, treatment, and outcome of psoas abscess from multicenter in Korea. Methods: We retrospectively reviewed the medical records of patients with psoas muscle abscess who were admitted to three university hospitals in Korea over 10 years. Results: A total of 87 patients (46 male, 41 female) were included in this study. The mean age was 56.3 ± 18.5 years old. The mean duration of hospitalization was 31.9 ± 24.37 days, time from admission to diagnosis was 13.6 ± 82.9 days. Fourteen cases as “secondary” abscess, and pyelonephritis (7/14, 50%) were most frequent etiology. Positive blood culture were obtained in 25% (27/81) and the causative pathogens were S. aureus (17/27, 62.8%), E.coli (4/27, 14.8%), Coagulase negative staphylococci (3/27, 11.1%), K. pneumoniae (2/27, 7.4%) and Candida species (1/27, 3.7%). Among 49 patients who were cultivated from abscess material, 41 microorganisms were grown in 34 patients (35/49, 71.4 %) and the most frequent organisms were S. aureus (17/35, 41.5 %) E. coli (6/35, 114.6%), K. pneumoniae (5/35, 12.2%). Forty patients(45.9%) underwent surgical debridement, 11 percutaneous drainage, 4 aspiration, and 31 patients were received only antibiotic treatment. The overall mortality was 10% (n=9). Comparison of treatment options showed mortality was not significant different between patients for only antibiotics and for antibiotics plus invasive procedure (12.9% (4/31) vs 8.9% (5/56), p=0.55). Conclusion: The etiology of psoas abscess can vary with each countries. In Korea, “primary” psoas abscess was more prevalent than “secondary” psoas abscess, and S.aureus was the most prevalent organism. The causative organisms can be identified by abscess culture in most cases. High index of suspicion is important to early diagnosis.

Albornoz 1 , D. Goleniuk 2 1 Hospital Departamental de Rivera and Cooperativa de Asistencia Medica de Rivera-FEMI , Montevideo, Uruguay, 2 Hospital Departamental de Rivera, Cooperativa de Asistencia Medica de Rivera-FEMI and Cooperativa Medica de Rivera, Rivera, Uruguay Background: Community-acquired Pneumonia (CAP) is still an important health problem with high mortality. Early identification of patients with severe CAP should improve the results. CURB- 65 score of the British Throracic Society is one of the simplest predictor's score of mortality and intensive care unit admission (ICU). Objetive: to validate the CURB-65 score in CAP patients admitted to three community hospitals in Rivera, Uruguay. Methods: A prospective cohort of CAP patients admitted between 1st May 2005 and 30th April 2007 was included and followed up until one year of hospital discharge. Area under the ROC and specificity and sensibility were estimated for CURB-65 score for 28 days-mortality and ICUadmission. Results: 495 patients (63 ± 19 years, male 53.9%) were included. 28-days mortality and ICUadmission were 20.8% (102/491) and 19.9% (98/492), respectively. 28-days mortality in patients with CURB-65 0, 1, 2, 3 and 4-5 was 4 (6/150), 14.2 (30/211), 43.6 (41/94), 67.7 (21/31) and 80% (4/5), respectively (p
