Publication Clinico-laboratory profile of haemolytic uremic syndrome(Kathmandu University, 2007) Jha, DK; Singh, R; Raja, S; Kumari, N; Das, BKAbstract Objective: To study the clinical profile, the spectrum of functional abnormalities, prognostic factors and outcome of children with haemolytic uremic syndrome (HUS). Materials and methods: This is a prospective, descriptive, single centre, cohort study, conducted on 42 children during the period of January 2004 to January 2005. Results: The maximum numbers of cases were below 24 months of age with mean age of 26.6 months and male: female ratio of 2.8:1. Most of the cases (79%) occurred in the warmer months (April-September). The common clinical presentations were bloody diarrhoea, pallor, oliguria & anuria, fever, vomiting, abdominal distension and pain, involvement of central nervous system, chest and cardiovascular system and bleeding manifestations. The common haematological abnormalities were leucocytosis, thrombocytopenia, anaemia and features of haemolysis in the peripheral blood. Electrolyte abnormalities observed were in the form of hyponatremia, hypokalemia and hyperkalemia. Arterial blood gas analysis showed metabolic acidosis in 64% cases, where the estimations were done. The mean blood urea and serum creatinine levels were 113.7 mg/dL and 2.5 mg/dL, respectively. Stool examination showed blood in all cases. Urine examination showed microscopic haematuria and significant proteinuria in 74% and 38% cases, respectively. E. coli and Shigella were isolated in stool in three cases each and one case showed mixed growth of E. coli and Salmonella. The mortality rate was 21%. Significantly higher mortality was observed in females, patients presenting with complete anuria, leucocytosis, hyperkalemia and systemic involvement like central nervous system, cardio vascular system and chest. Conclusions: Female sex, complete anuria, leucocytosis, extra renal involvement and hyperkalemia were associated with poor outcome.

Objective The objective of the study was to establish baseline indices of gallbladder volume for the Sikkimese population and determine its correlation with age, sex and Body Mass Index. Method A prospective epidemiologic study on selected 100 patients (equal male to female ratio) over the age of 36 years, undergoing ultrasound scan of abdomen, was undertaken. Age, sex, Body Mass Index and gall bladder volume for each subject were collected and analysed statistically. Spearman’s correlation test was performed to look for significant variables. Result The overall mean gallbladder volume in the present study was 15.47±7.9 ml with 17.2±8.9 ml and 13.74±6.4 ml being average volumes in males and females respectively, which gives the baseline indices for the Sikkimese population. Gall bladder volume was strikingly increased in obese subjects. There was a positive correlation between gall bladder volume and age (r=0.114), gender (r=0.182) and BMI (r= 0.175) but the strength of correlation was weak and not statistically significant (p <0.001). Conclusion Ultrasonography is an easy and effective method for evaluation of gall bladder volume. Sikkimese males have a larger fasting gall bladder volume which is directly correlated with higher body mass index. Fasting gall bladder volume has a weak correlation with advancing age.
