Abstract:
Corticosterone methyl oxidase type II (CMO II) deficiency is an uncommon cause of salt-wasting in infancy. We describe a boy who presented with recurrent dehydration and severe failure to thrive in the first 3 months of life, associated with mild hyponatraemia (serum Na+ 127-132 mEq/l) and hyperkalaemia (serum K+ 5.3-5.9 mEq/l). The diagnosis was suggested by an elevated plasma renin activity (PRA): serum aldosterone ratio, and subsequently confirmed by an elevated serum 18-hydroxycorticosterone: aldosterone ratio. Treatment with 9 alpha-fluorohydroxycortisone normalized growth parameters and PRA levels. CMO II deficiency should be considered in infants with recurrent dehydration and failure to thrive, even when serum sodium and potassium levels are not strikingly abnormal.

Adrenal Gland Disorders
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss.
