weakness of two month’s duration. She had been diagnosed with anorexia nervosa (binge-eating/purging subtype) at the age of 21 years. She had a history of repeated admissions for hypokalemia caused by self-induced vomiting and abuse of laxatives. On examination, her body mass index was 14.3 kg/m2. Laboratory values showed a serum creatinine level of 51.3 (normal 18–106) μmol/L, a serum potassiu...
OBJECTIVE To examine the frequency, severity, risk factors and mortality of hypokalemia, and efficacy of therapy used for its correction. DESIGN Descriptive, retrospective analysis. SAMPLE 290 patient records admitted consecutively to a Pediatric Intensive Care Unit (PICU) over a period of one year. RESULTS Forty three (14.8%) patients had 54 episodes of hypokalemia. Predisposing factors ...
Hypokalemia is a common clinical problem. The kidney is responsible for long term potassium homoeostasis, as well as the serum potassium concentration. The main nephron site where K secretion is regulated is the cortical collecting duct, mainly via the effects of aldosterone. Aldosterone interacts with the mineralocorticoid receptor to increase sodium reabsorption and potassium secretion; the r...
Anatomical lesions of hypothalamic area associated with hypodipsic hypernatremia have been reported only rarely. We report here a case of hypodipsic hypernatremia induced by a hypothalamic lesion. A 25-yr-old man, who had been treated with radiation for hypothalamic tumor 5-yr before, was admitted for evaluation of hypernatremia and hypokalemia. He never felt thirst despite the elevated plasma ...
We report a case of life-threatening hypokalemia in a 28-year-old bodybuilder who presented with sudden onset bilateral lower limbs paralysis few days after his bodybuilding competition. His electrocardiogram (ECG) showed typical u-waves due to severe hypokalemia (serum potassium 1.6 mmol/L, reference range (RR) 3.5-5.0 mmol/L). He was admitted to the intensive care unit (ICU) and was treated w...
Hypokalemia and hyperkalemia are common electrolyte disorders caused by changes in potassium intake, altered excretion, or transcellular shifts. Diuretic use and gastrointestinal losses are common causes of hypokalemia, whereas kidney disease, hyperglycemia, and medication use are common causes of hyperkalemia. When severe, potassium disorders can lead to life-threatening cardiac conduction dis...
