We report a 54-year-old male patient with phenotypic features of Cushing's syndrome with severe hypokalemia, metabolic alkalosis, hypertension an...

Actually, as the authors...

BACKGROUND Maternal electrolyte imbalance is rarely reported as causative factor of severe perinatal brain injury. CASE CHARACTERISTICS This case outlines a unique maternal and neonatal pseudo-Bartter syndrome presented with metabolic alkalosis and hypochloremia due to maternal severe vomiting. OBSERVATION Neonatal MRI brain revealed extensive brain hemorrhages with porencephalic cysts. Sub...

A 22 year-old lady with multi-drug-resistant pulmonary tuberculosis was on Kanamycin, Cycloserine, Ethionamide, Pyrazinamide and Moxifloxacin since more than two months. She presented with muscle cramps and carpopedal spasm. Investigation revealed hypokalemia and metabolic alkalosis. She also had hypomagnesemia, hypochloremia and hypocalciuria. Serum urea and creatinine levels were normal. Pati...
