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.

Aid post orderlies in one district of the Southern Highlands Province were trained to give immunizations to children as part of the Expanded Programme on Immunization. The performance of the aid post orderlies (APOs) as immunizers is compared with that of the traditional maternal and child health (MCH) team. Also the results of the combined efforts of the APOs and MCH sisters in this pilot district are compared with those in a control district. The joint APO-MCH effort was more successful than the traditional approach in reaching national immunization targets.
