Résumé
The pattern of Vibrio cholerae 01 and 0139 isolates at Indira Gandhi Medical College and Mayo General Hospital, Nagpur from 1993 to 2002 is presented. Emergence of the novel serotype 0139 in 1993 was followed by periods of quiescence and re-emergence. For the first time after 1993, the 0139 isolates out numbered 01 isolates in 2001. The peculiar epidemiological pattern is compared with other reports.

Seventy five clinically, biochemically and microscopically diagnosed cases of pyogenic meningitis including 28 adults and 47 paediatric patients were studied. Gram positive isolates in adults and gram negative bacilli in paediatric age group were the predominant organisms. Estimation of C-reactive protein (CRP) in cerebrospinal fluid (CSF) and serum was done in all cases as an early marker for rapid diagnosis of pyogenic meningitis. Simultaneous estimation of CRP levels in serum and CSF was found to have a significant diagnostic utility as compared to culture.
Résumé
Present study was carried out to evaluate oxidant-antioxidant status and effect of hemodialysis in acute and chronic renal failure. Serum MDA levels increased while serum SOD found decreased significantly. This study indicates the existence and increased production of an oxidizing stress resulting from hemodialysis and disturbance in antioxidant enzyme system.

To determine antiographic factors involved in left ventricular aneurysm formation after myocardial infarction, 50 patients with a first anterior wall myocardial infarction who underwent cardiac catheterisation within 6 months of infarction were evaluated. Extent of coronary artery disease and status of collateral circulation were studied in detail. Thirty patients had aneurysm in apical region while 20 patients showed aneurysm in anteroapical region. Coronary angiography revealed single-vessel disease in 17 patients, double-vessel disease in 17 patients and triple-vessel disease in 15 patients while in one patient coronary angiogram was normal. Fortynine patients showed significant involvement of left anterior descending artery which was poorly collateralised. Left anterior descending artery disease in association with inherent poor collateral blood supply may predispose for aneurysm formation after anterior wall myocardial infarction.
