OBJECTIVE: To study the presentation of @entity1143 among @entity779 @entity1 in Pakistan and to explore limitations in the diagnosis of these @entity1 by the physicians of a developing country. METHODS: We conducted a cross-sectional study on @entity1 admitted to Aga Khan University Hospital, Karachi, Pakistan from January 2005 to September 2008. Records of 663 @entity779 @entity1 were reviewed. Demographic data, @entity1576 , radiographic studies, and final outcome were studied. Presentation and radiological modality confirming the diagnosis of @entity1143 were noted. Descriptive statistics followed by Chi-Square test were applied, testing against an alpha of 0.05 and 95% confidence interval (CI). RESULTS: Three hundred and fifty-four (53%) out of a total of 663 @entity779 @entity1 did not complain of any respiratory symptoms at presentation, nor did their medical examination elicit any suspicion of PE. Hence, no radiological study was advised. Amongst the remaining 309 @entity1 , 299 (97%) underwent chest x-ray and 10 (3%) had abdominal ultrasound. The @entity1143 was noted in 50 (16%) @entity1 (31 male and 19 female @entity1 , with a mean age of 32+/-15 years). A @entity1143 was found in 23/50 (46%) @entity1 , left sided in 9/50 (18%), and 18/50 (36%) @entity1 had @entity1143 on both sides. Out of the radiologically confirmed @entity1143 @entity1 , 44/50 (88%) showed altered hemo-concentration with an insignificant odds ratio of 0.7 (p=0.56, 95% CI: 0.263-2.066). CONCLUSION: Compared to other studies, fewer numbers of our @entity1 suffered from @entity1143 . The diagnostic modality preferred by the physician was the chest x-ray.
