OBJECTIVES: To review if there is a change in the maternal mortality rate at the Kenyatta National Hospital since the inception of the Millennium Development Goal strategy in 1990, compared to earlier reviews. DESIGN: A retrospective descriptive study. SETTING: Kenyatta National Hospital. SUBJECTS: Maternal deaths attributed directly to obstetric causes. MAIN OUTCOME MEASURES: Determination of maternal mortality rates of all patients admitted to the Kenyatta National Hospital Maternity and died after admission up till six weeks of admission. Also determine any avoidable causes of the same. RESULTS: During the period under review, there were 27,455 deliveries and 253 maternal deaths giving a maternal mortality ratio of 921.5 per 100,000 live births. Direct obstetric causes accounted for 71% of all maternal deaths with sepsis, haemorrhage, and hypertension being the leading causes. Respiratory tract infections associated with HIV/ AIDS infection was the prominent indirect cause. 67.5% of deaths occurred in women aged between 25 and 35 years and 78.7% were Para 2 or less. Evidently there was poor antenatal clinic attendance with only 28.6% having had any attendance at all. CONCLUSION: Antenatal clinic attendance needs to be re-emphasised if an impact is to be realised in curbing maternal mortality; moreover there is need for early referrals and encouraging mothers to deliver under skilled care.

Rukaria-Kaumbutho, RM, Ojwang SB, Oyieke JB.  1996.  Resistance to chloroquine therapy in pregnant women with malaria parasitemia. Abstract

The objective of the study was to determine the efficacy of chloroquine in pregnant women with Plasmodium falciparum parasitemia at therapeutic doses of 25 mg/kg body weight divided over 3 days. METHODS: Three-hundred pregnant women in Kilifi Hospital at the coast of Kenya were screened for malaria parasitemia using Giemsa stained thick blood smears. In vivo and in vitro parasite sensitivity to chloroquine was determined. RESULTS: P. falciparum infections were present in 65 (22%) of 300 pregnant women. The in vivo tests showed that 46% of all the P. falciparum infections were resistant to chloroquine predominantly at RI and RII levels. The in vitro tests showed a resistance rate of 35%. CONCLUSIONS: A large proportion of pregnant women with malaria do not respond to chloroquine therapy and alternative drugs are required

In a malaria-endemic area of the Coast of Kenya with chloroquine resistant Plasmodium falciparum, we determined the prevalence and density of falciparum infection in gravid women and assessed the in vivo and in vitro parasite response to a regimen of chloroquine 25 mg/kg body weight divided over three days. P. falciparum infections were present in 65 (21.7%) of 300 pregnant women. The proportion of primigravidae who were parasitaemic was 41.8% which was significantly higher than that of the multigravidae (17.1, P less than 0.01). Primigravidae did not show a significantly higher mean parasite density than the multigravidae. The in vivo tests showed that 45.9% of all the P. falciparum infections were resistant to chloroquine predominantly at RI and RII levels with percentages 36.1% and 8.2%, respectively. PIP: At the antenatal clinic of Kilifi District Hospital in the Coast Province of Kenya, researchers enrolled 300 pregnant volunteers 15-32 years olds, living in the district to screen and treat then for Plasmodium falciparum infection and to follow those with parasitemia on days 0, 1, 2, 14, 17, 21, and 28. They also conducted in vitro studies to determine resistance to chloroquine. They combined in vivo and in vitro study took place between November 20, 1988 and January 17, 1989. 65 women (21.7%) had P. falciparum in their peripheral blood smear. Primigravidae were more likely to be parasitemia than were multigravidae (41.8% vs. 17.1%; p .001). Their mean parasite density was also higher but not significantly so. Parasite density fell consistently with rising parity. Malaria infections in 54.1% of the women responded to 25 mg/kg chloroquine. the remaining 45.9% (28) of cases exhibited in vivo resistance, especially at RI an RII levels (36.1% and 8.2%, respectively). Primigravidae were more likely to experience failure to clear parasites by day 7 than multigravidae. Further, among women experiencing a parasitemia on day 7, parasites tended to reappear on day 14 and 21 in primigravidae. Initial parasite density did not affect clearance of parasites. Primigravidae continued to have a higher level of parasitemia throughout treatment than did multigravidae. It took at least 24 hours for the chloroquine to be completely absorbed thus the mean level of parasitemia decreased sharply between 0-2 days. Amodiaquine induced a parasitemia in 89.3% (25 cases) of the chloroquine resistant infections. Even though the 3 remaining cases with parasitemia received amodiaquine treatment, clinicians administered Fansidar, resulting in a clearing of parasitemia in 7 days. 34.8% of in vitro parasite cultures were resistant to chloroquine. The reduced ability of pregnant women to clear parasitemia likely explained the lower level of in vitro resistance.

PIP: In this study, 273 university students (161 men and 112 women) were interviewed by means of a self-administered questionnaire to determine their knowledge, attitude, and practice concerning sexually transmitted diseases (STDs). The mean age of the men was 22.4 +or- 1.6 years and that of the women was 22.1 +or- 1.6 years. 97.4% of the students were sexually experienced. Knowledge of common STDs was high, but knowledge of their signs, symptoms, and consequences was low. 24.5% of the male and 3.7% of the female students had had an STD. The principal sources of information on STDs included books, films, and TV for 39.6% of the students and teachers for 16.8% of the students. Parents played a very minimal role. It is suggested that primary and secondary school students be taught about STDs as part of reproductive health education and that such education be continued at the college level in order to increase the awareness among young people. author's modified

PIP: The efficacy and complication rate of menstrual regulation with the hand-held Karman cannula was tested on 223 women with amenorrhea up to 56 days in the Dept. of Obstetrics and Gynecology, University of Nairobi, Kenya from October 1982-January 1983. 195 women had positive pregnancy tests, while menstrual regulation was done on the others because of concern over late menses. the procedures were done without anesthesia with a 50 ml vacuum syringe fitted with a self-locking plunger, a rubber adaptor and stop cock, 5-8 mm flexible plastic Karman cannula and a toothless volsellum, using hibitane solution and savlon antiseptic. The average procedure time was 7 minutes. Bleeding lasted over 1 week in 4%, total blood loss was over 50 ml in 3.1%, and immediate side effects were syncope in 1.3%, nausea and vomiting in 1.8% and pain in 5.4%. There were 2 (0.8%) cases of endometritis. In Kenya where 60% of all gynecological hospital admissions are for septic abortions, it is essential to provide safe termination as a backup for family planning method failures.
