OBJECTIVES Amphotericin B-induced nephrotoxicity is frequent, severe and associated with an increased risk of death. Patients with underlying renal disease are considered to be at high risk for amphotericin B nephrotoxicity. Amphotericin B is a molecule that is highly protein bound over a wide range of protein and drug concentrations, including those seen in patients with >or= 3 + proteinuria. ...

BACKGROUND Potassium and magnesium depletion prolongs the duration of the action potential of the cardiomyocyte, which predisposes to ventricular arrhythmias. In addition, potassium or magnesium depletion might impair cardiac performance and facilitate coronary artery thrombosis. METHODS Continuous 24-h ambulatory electrocardiographic monitoring, treadmill exercise testing and echocardiograph...

BACKGROUND Northern Territory Aboriginal children hospitalised with acute gastroenteritis have high rates of acidosis, hypokalaemia, and dehydration. AIMS To determine whether Aboriginal children with and without diarrhoea have greater impairment in intestinal function than non-Aboriginal children, as assessed by increased permeability ratios. METHODS A descriptive study of 124 children (96...

Neuroendocrine Carcinoma of the Prostate (NECP) is rare and only few cases have been reported, constituting less than 0.5% of prostatic malignancies. We report a rare case of large bowel obstruction from NECP posing a further challenge in management due to resistant hypokalaemia. A 70-year-old man presented with clinical signs of large bowel obstruction who was known to have prostatic carcinoma...

BACKGROUND Hypokalaemic nephropathy has been described in patients with chronic potassium depletion; it is a condition in which proximal tubular vacuolization and interstitial fibrosis occur, resulting in a decline in glomerular filtration rate (GFR) and, in some cases, renal failure. It has been described in patients with chronic diarrhoea, eating disorders, laxative abuse and primary hyperald...

UNLABELLED Hypokalaemia may present as muscle cramps and Cardiac arrhythmias. This is a condition commonly encountered by endocrinologists and general physicians alike. Herein, we report the case of a 43-year-old gentleman admitted with hypokalaemia, who following subsequent investigations was found to have Gitelman's syndrome (GS). This rare, inherited, autosomal recessive renal tubular disord...

OBJECTIVE To determine the frequency of hyponatraemia and hypokalaemia in malnourished children with acute diarrhoea. METHODS This cross-sectional study was carried out at the Military Hospital, Rawalpindi, Pakistan, from September 2013 to March 2014, and comprised acute diarrhoea patients whose ages ranged from six months to five years. Blood samples for serum sodium and potassium were exami...

We describe a patient presenting with hypertension and hypokalaemia who was ultimately diagnosed with liquorice- induced pseudohyperaldosteronism. This rare cause of secondary hypertension illustrates the importance of a methodical approach to the assessment of hypertension.
