Endemic malaria still exists in the Republic of Vanuatu, an 80-island archipelago that sits astride the southeast margin of the Southeast Asian-Melanesian malaria band (Buxton Line 170 degrees E, 20 degrees S). The annual parasite incidence has decreased dramatically over the past decade, which has been attributed to an intensive insecticide-treated bednet distribution program and implementation of a revised Plasmodium falciparum treatment policy that employs combination chloroquine + sulfadoxinelpyrimethamine as a first-line therapy. Standard malariometric surveys were conducted at 10 locations in 2 provinces, screening 2351 adults and children towards the end of the peak transmission season. Spleen rates were consistent with mesoendemic malaria. Examination of blood slides revealed a mean slide-positive rate of 22% (range 4% to 33%). P. falciparum predominated, accounting for 73% of infections, followed by P. vivax (25%). Among 396 individuals with P. falciparum, the gametocyte rate was 54%, with 37% presenting gametocytes alone without asexual stages. Only 8% and 4% of persons with asexual stage P. falciparum and P. vivax parasitaemia, respectively, were symptomatic. These data suggest that malaria transmission has increased in some locations in Vanuatu over the past decade and this report underscores the importance of appropriate bednet use and vector control in this setting as well as the impact of adding sulfadoxine/pyrimethamine and removing primaquine from the national malaria treatment formulary.

This paper provides accurate figures and detailed analysis of the causes of perinatal mortality in the main referral hospital in Vanuatu in 1992, and discusses possible improvements in management. The perinatal mortality rate for the Vila Central Hospital area was 30.4 per 1000 births (with a stillbirth rate of 14 per 1000). These figures include mothers who presented for the first time in labour without any antenatal care, and cases of very low birthweight (less than 1 kg). These results were achieved with very low intervention rates. The commonest cause of death in Vanuatu was birth asphyxia, with prematurity, unexplained stillbirth and major congenital abnormality as the other main causes. Even though there is still scope for improvement, especially in the prevention of birth asphyxia, the perinatal mortality rate in Vanuatu compares favourably with that in other developing countries. Increased family planning uptake will be expected to lead to a reduction in perinatal mortality.

A review of cases of ectopic pregnancy operated upon at Vila Central Hospital during 1992 with an analysis of clinical presenting features and diagnostic factors is presented. Comparison is made between hospital, regional and national figures and possible explanations for the differences are given. Recommendations are made to ensure that ectopic pregnancy is always at the forefront of differential diagnosis in women presenting with abdominal pain.
