Malaria is a major problem in Papua New Guinea, where it accounts for a high proportion of sickness and death. In addition to the human suffering, malaria also puts severe stress on the health services, and may directly hinder economic growth. ⋯ Through the malaria vaccine program at the Papua New Guinea Institute of Medical Research, Papua New Guinea is playing a significant role in the global effort to develop a malaria vaccine, and ensuring that the malaria patterns of the Asia-Pacific region figure strongly in vaccine development strategies. Discussed here are some of the major issues to be considered as we work towards a malaria vaccine for Papua New Guinea.

Hyponatraemia (serum sodium level below 130 mmol/l) is a common electrolyte abnormality in a hospital population. It can be associated with dehydration, overhydration or normal hydration. Clinically, it is important to recognize the common diseases associated with hyponatraemia since correct treatment in terms of fluid replacement is essential in preventing complications of low serum sodium. ⋯ Hyponatraemia was more common in medical (38%) and paediatric (35%) cases and at the extremes of ages, ie, under the age of 6 years and above 40 years. Over a quarter of the hyponatraemic patients had severe hyponatraemia (serum sodium below 120 mmol/l). Clinical conditions commonly associated with hyponatraemia, in descending order of importance, were diarrhoea and vomiting, renal failure, central nervous system infections and trauma, pulmonary infections, oedematous states (eg, nephrotic syndrome) and diabetes mellitus.
