Treatment of lower ureteric stones by ESWL and ICPL: a comparative study.

This study was carried-out to find-out better and effective treatment option for Lower Ureteric Stones (LUS) by comparing Extracorporeal Shock Wave Lithotripsy (ESWL) with ureterorenoscopic (URS) Intracorporeal Pneumatic Lithotripsy (ICPL). A total of 60 patients attending the outpatient department of Bangabandhu Sheikh Mujib Medical University (BSMMU) with lower ureteric stones were divided into two groups, 30 in group-I (URS + ICPL) and the remaining 30 in group-II (ESWL). In group-I, 60% were male with mean age of 32.76 years and in group-II, 40% were male with mean age of 36.23 years. The ratio of involvement of right to left ureter was 1.7:1. The mean stone size was 10.7 + 2.69 mm (SD) in group-I and 9.9 + 1.97 mm (SD) in group-II. The differences in age, sex and side of involvement of ureter were not significant (p > 0.05) between the two groups. Among the groups 24 (80%) in group-I and 26 (86.61%) of patients in group-II were found stone free. The post procedure loin pain, fever and haematuria were more common in group-I than in group-II. The LUTS and loin pain were significantly more in group-I than in group-II (p < 0.05). The post procedure fever was significantly more in group-I than in group-II (p < 0.001). The mean post procedure hospital stay was 5.7 + 2.54 days for group-I and 1.57 + 0.531 days for group-II. Post procedure hospital stay was significantly less in group-II than in group-I (p < 0.05). The post procedure follow up attendance in this study was significantly low in group-I than in group-II (p < 0.05). ESWL was found effective method than URS + ICPL for the treatment of lower ureteric stones.

Prognostic factors relating to outcome of severe malaria among children in Bangladesh.

This study was done in the Paediatric in-patient department of Chittagong Medical College Hospital (CMCH), Chittagong, Bangladesh to identify and quantify the prognostic factors associated with increased mortality in severe malaria (SM) cases. All the patients with parasitologically confirmed clinical syndromes of SM, admitted between June 1997 and May 1998, were included. A total of 53 consecutive cases were studied. Cerebral malaria (CM) was the commonest type of SM, observed in 36(68%) cases, second commonest type was severe anaemia 13(25%). More than one type of severe manifestations were present in 23(44%) cases. Overall case fatality rate (CFR) was 17% and it was 30% among those who had multi-organ manifestations. Important poor prognostic clinical variables were Blantrye coma score (BCS) score of 0 and 1 on day 1 (OR = 7.78) and day 2(OR = 40.0), multi-organ manifestations (OR = 6.8) and in-hospital complications (OR = 5.18). Important poor prognostic laboratory variables were day 2 parasite count > 50,000/cmm (OR = 5.5), blood glucose < 2.2 mmol/l (OR = 21.5) and raised CSF protein > 50 mg/dl (OR = 7.0). It can be concluded that certain clinical variables e.g. low BCS on day 1 & 2, multi-organ manifestations, in-hospital complications; and laboratory variables e.g. high parasite count, low blood glucose level, raised CSF protein levels are associated with increased mortality rate in SM cases.

Isolation and characterization of Helicobacter pylori strains from peptic ulcer patients in Dhaka, Bangladesh.

To study the association of Helicobacter pylori with peptic ulcer and the associated histopathological changes, to characterize the isolated strains in terms of their protein profile, 83 peptic ulcer cases were studied. A high association of H pylori with peptic ulcer (duodenal ulcer 77%, gastric ulcer 75%) and gastritis (74%) was observed. Age and smoking did not have any relationship with H pylori infection. The infection was predominantly associated with the 'quiescent' form of chronic gastritis. Comparative sodium dodecyl sulfate polyacrylamide gel electrophoresis of whole cell extracts of the local isolates and a reference strain from Australia showed a general homogeneity between the strains with obvious interstrain differences. However, the difference between the local isolates and the reference strain was more marked. Significant association of H. pylori with peptic ulcer along with strain variations were observed.
