Bartter Syndrome: Renal tubulopathy with hypokalaemic alkalosis, high renin and aldosterone, normal BP, and polyuria—mimics loop diuretic effect at the thick ascending limb.

William B. Schwartz (1922–2009) American nephrologist. Co-described SIADH, pioneered decision theory, medical AI, and ethical health care rationing.

Schwartz-Bartter Syndrome (SIADH): Excess ADH leads to water retention and dilutional hyponatraemia, with low serum sodium and osmolality but inappropriately concentrated urine.

Gitelman Syndrome: Inherited defect in Na⁺-Cl⁻ cotransport in the distal tubule, causing hypokalaemia, alkalosis, hypomagnesaemia, and hypocalciuria—thiazide-like effect.

Liddle Syndrome: Monogenic hypertension due to ENaC overactivity in the collecting duct. Causes sodium retention, hypokalaemia, low renin and aldosterone—pseudo-aldosteronism.

Swiss paediatrician Guido Fanconi (1892–1979) defined Fanconi anaemia and Fanconi syndrome, shaping modern paediatrics and medical genetics.

Hillel J. Gitelman (1932–2014) American nephrologist. Described Gitelman syndrome, a renal tubulopathy mimicking thiazide effect with hypokalaemia and hypomagnesaemia.

Frederic Crosby Bartter (1914–1983) American endocrinologist. Defined Bartter syndrome, co-described SIADH, and advanced adrenal and renal physiology.

Grant Winder Liddle (1921-1989) American endocrinologist. Pioneer of endocrine diagnostics; discovered Liddle syndrome, developed suppression tests, and defined ectopic ACTH

A 30 year old woman who is currently 30 weeks gestation presents to the ED with abrupt, severe right loin pain.

Exploring the Point of Care Ultrasound Essentials course with a video demonstrating the renal and bladder ultrasound examination to identify hydronephrosis.

In this video Joel Topf looks at three types of potassium wasting nephropathies: Polyuria; distal RTA; and hypomagnesemia...and how each can lead to hypokalemia.
