Late presentation characterises chronic kidney disease in sub-Saharan Africa. Hypertension and proteinuria are independent risk factors for worsening kidney function, irrespective of the cause of the kidney disease. We assessed the prevalence and predictors of hypertension and proteinuria in an outpatient population in Northern Ghana.\u0000Methods: We retrospectively reviewed screening data among adults ≥18 years of age in two of Ghana’s Northern regions. The data retrieved included socio-demographic information, blood pressure recordings, urine dipsticks and fingerpick blood glucose levels. The data were analysed for the prevalence of hypertension and proteinuria in the participants. Binary logistic regression analysis was employed to identify the predictors of significant proteinuria in these participants. A p-value <0.05 was considered statistically significant.\u0000Results: Total 1018 participants were included in the study, comprising 50.5% males. The prevalence of uncontrolled hypertension was 28.1%, using a blood pressure cut-off value of ≥ 140/90 mmHg. Significant proteinuria (≥ 1+ or 30 mg/dl) was present in 10.7% of the participants.

Objective was to study the predictive scoring pattern in difficult laparoscopic cholecystectomy cases.\u0000Methods: It was a prospective observational study. Ninety cases of suspected cholecystitis were identified for study presented to Jehangir hospital, Pune with upper abdominal pain or vomiting or dyspepsia or jaundice. Such patients were studied in detail clinically, admitted and investigated. Ultrasound abdomen was done in all patients.\u0000Results: Out of 90 cases studied, 64 patients (71.1%) had pre op score between 0-5 i.e. easy level, 21 patients (23.3%) had pre-op score between 6-10 i.e. difficult level and 5 patients (5.6%) had pre-op score between 11-15 i.e. very difficult level against intra-op scoring of 57 patients (63.33%) being easy, 28 patients (31.1) difficult and 05 patient (5.6%) had very difficult surgery.
