Renal tubular acidosis in Papua New Guinea

Unlike most other inborn errors of metabolism, which require advanced and expensive diagnostic techniques and complex drug and dietary management (often not feasible in developing countries), the renal tubular acidoses may be detected and treated both easily and cheaply. Diagnostic confusion is possible as this series demonstrates due to the protean clinical manifestations. Three recent cases from Port Moresby General Hospital are described and appropriate investigations and treatment discussed.
