Background: Emphysematous renal tract disease (ERTD) is a rare necrotizing infection of the renal parenchyma and urinary tract caused by gas-producing organisms. ERTD deserves special attention because of its life-threatening potential. Objectives: To study the clinical features, radiological classification and prognostic factors of ERTD; and to compare the modalities of management and the outcome among the various radiological classes of ERTD. Patients and Methods: Twenty consecutive patients with diabetes and ERTD, seen over last 3 years in a tertiary care institute of north India, were included in the study. All patients were subjected to computerized tomography (CT) after initial diagnosis by ultrasonography. They were classified into 5 classes as previously described. All patients included in the study were conservatively managed with appropriate antibiotics and/or percutaneous drainage or surgery if required. Result: Mean age (± SD) of these subjects was 54.4 ± 20.6 years; duration of diabetes mellitus 8.6 ± 5.8 years, and duration of symptoms related with ERTD ranged from 3 days to 3 months. Two patients had isolated emphysematous cystitis, 13 patients had emphysematous pyelonephritis (EPN), 3 had both EPN and cystitis, and 1 patient had EPN with cholecystitis, and 1 patient had EPN with pyomyositis. Only 7 (35%) patients had a history of pneumaturia. Escherichia coli was the commonest microorganism. The radiological distribution in 18 (2 had isolated cystitis) patients with EPN was: 2 patients had class 1; 1 had class 2; 2 had class 3A; 11 had class 3B, and 2 had class 4. Of 20 patients 11 (55%) survived. However, those patients who died had severe EPN based on radiological class (6 had class 3B and 1 had class 4). There was no significant difference between the survivor and non-survivor groups with respect to age, gender, duration of diabetes mellitus, duration of symptoms, serum creatinine level, total leukocyte count, hemoglobin, platelet count and culture positivity. Conclusion: Computerized tomographic class 3B or 4 is the most reliable predictor of outcome in patients with ERTD.

Background: Vitamin D toxicity (VDT), a “not uncommon” cause of hypercalcemia, can be life-threatening and cause substantial morbidity, if not treated promptly. Aims: To describe presentation, management, and outcome in 32 patients with VDT diagnosed over 3 years. Materials and Methods: Patients presenting with VDT at a tertiary care centre in Srinagar Kashmir India were included. Evaluation included detailed history and biochemical tests including serum calcium, phosphate, creatinine, intact parathyroid hormone (iPTH), 25-hydroxy Vitamin D (25-OHD), and 24-hour urinary calcium. Results: The clinical manifestations of the 32 patients (median age 65; range 3–77 years) included gastrointestinal symptoms (constipation and vomiting), polyuria/polydipsia, altered sensorium, pancreatitis, acute kidney injury, and nephrocalcinosis. The median total serum calcium level was 13.95 (range 11.10-17.20) mg/dl and median 25-OHD level was 306 (range 105–2800) ng/ml. All patients had suppressed or low normal iPTH and hypercalciuria and 78% had azotemia. All patients had received multiple intramuscular injections of vitamin D 3 . The median cumulative dose was 4,200,000 (range, 1,800,000-30,000,000) IU. The median time to resolution of hypercalcemia was 7 months (range 4–18 months). Conclusion: We conclude that VDT is an increasingly common cause of symptomatic hypercalcemia. VDT needs prolonged follow up as it takes months to abate its toxicity. Enhancing awareness among general practitioners regarding the toxicity resulting from high doses of vitamin D is the key to prevent VDT. We suggest that VDT be considered in patients, especially the elderly, presenting with polyuria, polydispsia, vomiting, azotemia, or encephalopathy.

Background: There are scarce data on the prevalence of thyroid disorders and urinary iodine status among tribal populations of India, with no reported data from Kashmir valley. Conclusion:These novel data on iodine and thyroid status among a tribal population of India generally inhabiting in remote sub-Himalayan belts demonstrate high prevalence of subclinical hypothyroidism (SCH) with persistent iodine deficiency. These preliminary data may warrant large well-designed studies to carry out comprehensive assessment of the problem in this high-risk and marginalized population.
