Although specific treatment is available for Lassa fever, early diagnosis is still difficult in most Nigerian primary and secondary health centers. This study was carried out to compare the case-fatality rates of Lassa fever and other medical diseases commonly seen in adult medical wards, to determine the community habits that make Lassa fever endemic in Edo Central District of Nigeria, with the aim of prescribing preventive measures for its control in Nigeria. The records of 908 inpatients in the adult medical wards of Irrua Specialist Teaching Hospital, Irrua and responses from respondents interviewed by trained interviewers on their knowledge, attitudes and practices pertaining to Lassa fever were used for this study. The case-fatality rate of Lassa fever in this center was 28%. Cultural factors and habits were found to favor endemicity of Lassa fever in Edo Central District of Nigeria. Preventive measures were prescribed for families and communities.

Summary:Increased gestational weight gain is associated with higher rates of complications of pregnancy and delivery. Gestational weight gain of 9-12 Kg has been associated with the best outcome for both mothers and infants. However, weight gain in most pregnant women is not within this range, perhaps due to the difficulty of calculating the exact quantity, timing and duration of dietary restriction in individual patients that would bring their weight gain within the normal range. There is therefore a need to develop a drug or food supplement that would reduce weight gain without causing adverse effects on the fetus. Aframomum melegueta is widely used in Nigeria by most people including pregnant women for various purposes. It is against this background that the present investigation examines the possibility of its beneficial effects on pregnancy, using Sprague Dawley rat as the animal model. Twenty female and ten male Sprague-Dawley rats of proven fertility from a pilot study were randomly mated in groups of two females and one male. Three days later, female rats in the experimental groups were given intra-peritoneal injections of 0.5 mg, 1 mg, 1.5 mg and 2 mg of aqueous extract of alligator pepper respectively while the control had 2 ml of distilled water.. All rats were observed for 18-25 days. There was a significant (P<0.05) reduction in gestational weight gain of the experimental rats. The litters were not adversely affected. It is suggested that the active component of aqueous extract of alligator pepper be determined because of its beneficial effect of gestational weight gain reduction.

Summary: Alligator pepper (Aframomum melegueta) is a spice that is widely used in many cultures for entertainment, religious rites, food flavor and as a part of many traditional doctors medications. Pregnant women are among those who ingest Alligator pepper in these activities. This experiment was carried out to determine the health risk or benefit of Alligator pepper to pregnant women if any. Fifteen male rats and fifteen female rats of proven fertility from a pilot study were randomly paired in fifteen cages in a well ventillated room. After three days of mating, the males were withdrawn from the females, which were allowed to stay in their separate maternity cages for 18-25 days. The females in the control group were fed with normal rat chow and clean drinking water ad libitum for the duration of the experiment. Each of the rats in the experimental group was served 20 g of rat chow mixed with 50mg of Alligator pepper for one day only and thereafter fed with normal rat chow and clean drinking water ad libitum for 18-25 days. The rats in the control group had a mean of 7 litters each, while the rats in the experimental group did not litter at all. It was concluded that ingestion of large quantities of Alligator pepper poses a health risk to women in their first trimester of pregnancy.
