RESUMEN
Working alongside local stakeholders, members of the French-African Pediatric Oncology Group developed a 3-year program to train pediatric oncology teams from 15 French-speaking countries in Africa in using analgesics and providing palliative care. This program was rolled out in three phases: initial training, in situ assessment, and advanced training in selected topics. To access this program, multidisciplinary teams had to come up with a project to improve their existing palliative care and pain management practices, and commit themselves to implementing it. All the teams invited agreed to take part in the program, which explicitly broached a subject that is often avoided in oncology teaching. The first phase was rolled out in 2017, with 65 trainees from 19 units attending one of three sessions held in Dakar, Senegal, Abidjan, Côte d'Ivoire, and Rabat, Morocco. The subsequent assessment revealed that only half the teams had started to implement their projects. The advanced training phase was therefore adjusted accordingly. A collective training session held in Marseille was attended by 15 trainees from seven teams whose projects were already underway, while in situ mentoring was provided for six other teams, through French-African twinnings in four cases. The length and openness of the program meant that we were able to identify and share the units' diverse realities, and fine-tune their projects accordingly, as well as plan ways of continuing the training both locally and collectively.

Primaquine, an 8-aminoquinoline, is a relatively unknown and underutilized drug in French-speaking African countries. It acts against the liver stage parasites of all human malaria species, asexual blood stages of Plasmodium vivax and, to a lesser degree, Plasmodium falciparum; P. falciparum mature gametocytes, and P. vivax and Plasmodium ovale hypnozoites. Gastrointestinal disturbances are its most common side effects. The clinical utility of primaquine is limited due to its hematological side effects in individuals with glucose-6-phosphate dehydrogenase (G6PD) deficiency and other contraindications (pregnant woman, breastfeeding woman, infants less than 6 months old). In the light of the recent recommendations of the World Health Organization (WHO), we propose to examine how primaquine can be used in French-speaking Africa to improve malaria control and move towards malaria elimination. Two indications supported by the WHO are of relevance in Africa. First, artemisinin-based combination therapies and primaquine given as a single low dose (0.25 mg base/kg) are effective to kill asexual and sexual parasites of P. falciparum, are well-tolerated, and have very little risk even in mild to moderate G6PD-deficient patients. This strategy may be helpful to contain transmission in an area in Africa where P. falciparum malaria incidence has decreased considerably. There is an ethical concern in administering primaquine as a gametocytocide as it does not confer any direct benefit to the treated patient. However, the single low-dose primaquine is most likely associated with very low risk for adverse hematological effects, and WHO recommends its use even without prior G6PD testing. In our opinion, clinical studies including G6PD test should be conducted to assess the safety of low-dose primaquine in African patients. Second, primaquine is effective and necessary for radical treatment of P. vivax and P. ovale, but the standard 14-day treatment (0.25-0.5 mg base/kg/day) is not recommended in patients with G6PD deficiency. Prior G6PD testing is required before prescribing primaquine for radical treatment. The use of primaquine for radical treatment in patients without contraindications does not raise any major ethical problem since the probability of relapse in patients who do not receive anti-hypnozoite treatment can be relatively high and each relapse can cause or aggravate anemia, especially in children. In our opinion, patients with mild or moderate G6PD deficiency should not be treated with primaquine at present. Further clinical studies are necessary to define the role of this drug for radical treatment in G6PD-deficient African patients. Without primaquine, the eventual elimination of P. vivax and P. ovale malaria appears to be very difficult. Updated epidemiological data on G6PD, Duffy antigen, and the current distribution of and burden due to P. vivax and P. ovale are required for a rational use of primaquine in the African continent. Moreover, clinical studies on primaquine are required in Africa.

The provision of a secure and safe blood supply has taken on new importance in sub-Saharan Africa with the onset of the AIDS epidemic. Blood transfusion services capable of providing safe blood are not cheap, however, and there has been some debate on the desirability and sustainability of different financing mechanisms for blood transfusion services. This paper examines patterns of financing blood transfusion in three countries--Côte d'Ivoire, Zimbabwe and Mozambique. It goes on to consider the conceptual options for financing safe blood, and to examine in detail the possible role of user fees for blood transfusion in Africa, developing a simple model of their likely burden to patients based on data from Côte d'Ivoire. The model indicates that, at best, there can only be a limited role for user fees in the financing of safe blood transfusion services, due mainly to the relatively high cost of producing a unit of safe blood. Charging individuals for the blood they receive is likely to be administratively complex and costly, could realistically recover only a fraction of the production costs involved, and is further complicated by the fact that the main recipients of blood transfusion in sub-Saharan Africa are children and pregnant women. If cost-recovery for safe blood is to be attempted, the most viable option appears to be that of charging a collective fee, levied upon all inpatients, not just on those who receive blood. Such a mechanism is not without problems, not least in its failure to offer incentives for more appropriate blood use, and it is still likely to recover only a portion of the costs of producing safe blood. Whether or not cost-recovery is instituted, there will remain an important role for public funding of blood transfusion services, and, by implication, an important role for foreign donor support.

BACKGROUND: Pregnancy is associated with increased susceptibility to malaria. It is generally agreed that this increased risk ends with delivery, but the possible persistence of increased susceptibility during the puerperium had not been investigated. METHODS: From June 1, 1990, to December 31, 1998, we monitored exposure to malaria, parasitemia, and morbidity among the residents of a village in Senegal in which the rate of transmission of malaria was high. In this population we analyzed 71 pregnancies in 38 women from the year before conception and through one year after delivery. RESULTS: Among the 38 women, there were 58 episodes of clinical Plasmodium falciparum malaria during 61,081 person-days of observation. The incidence of malaria was 20.2 episodes per 1000 person-months during the year preceding conception and 12.0 episodes per 1000 person-months during the period from 91 to 365 days after delivery. The incidence of episodes of malaria increased significantly during the second and third trimesters of pregnancy and reached a maximum of 75.1 episodes per 1000 person-months during the first 60 days after delivery. The adjusted relative risk of an episode of malaria was 4.1 (95 percent confidence interval, 1.8 to 9.5) during the first 60 days post partum, as compared with the year preceding pregnancy. The duration of fever during the episodes of malaria was longer and the prevalence and density of asymptomatic malarial parasitemia were significantly higher during pregnancy and the early postpartum period than during the other periods. CONCLUSIONS: Among women who live in areas with high rates of transmission of malaria, the susceptibility to malaria is highest during the second and third trimesters of pregnancy and the early postpartum period.

BACKGROUND: Tafenoquine is an analogue of primaquine with an improved therapeutic and safety profile. It has a long half-life and activity against liver-stage malaria parasites, so may be useful for chemoprophylaxis. In this randomised, double-blind study we assessed the efficacy and safety of tafenoquine in different doses. METHODS: 2144 individuals aged 12-20 years living in Lambaréné, Gabon, an endemic area for Plasmodium falciparum malaria, were invited to take part. 535 attended, and 426 eligible participants were randomly assigned tafenoquine (250 mg, 125 mg, 62.5 mg, or 31.25 mg) or placebo daily for 3 days. 417 received initial curative treatment with halofantrine, and 410 completed the assigned prophylaxis regimen. During follow-up of 70 days, adverse events were recorded and thick blood smears were examined weekly. The primary and secondary endpoints were the number of individuals with positive blood smears by day 56 and day 77, respectively. Analyses were per-protocol. FINDINGS: Eight positive blood smears were recorded by day 56 (four/82 participants in the placebo group; four/79 tafenoquine 31.25 mg group). By day 77, 34 positive blood smears had been recorded (14/82 placebo; 16/79 tafenoquine 31.25 mg; three/86 tafenoquine 62.5 mg; one/79 tafenoquine 125 mg; none/84 tafenoquine 250 mg). Numbers of adverse events did not differ significantly between the treatment groups. INTERPRETATION: Tafenoquine is effective and well tolerated. It has the potential to replace currently used drugs for malaria chemoprophylaxis.

To identify factors associated with improved performance of health care workers who treat ill children in developing countries, the authors analyzed a sample of consultations of children with malaria (defined as any fever) from a national health facility survey conducted in the Central African Republic from December 1995 to January 1996. Twenty-eight health care workers and 204 children were studied. A univariate analysis revealed the following significant predictors of correct treatment, as defined by the Central African malaria control program: high fever (odds ratio (OR) = 3.25, 95% confidence interval (CI): 1.47, 7.17); correct health care worker diagnosis (OR = 2.59, 95% CI: 1.39, 4.85); and the caregiver's reporting the child's fever to the health care worker (OR = 2.18, 95% CI: 1.32, 3.62). There was an unexpected inverse association between the presence of a fever treatment chart and correct treatment (OR = 0.19, 95% CI: 0.04, 0.91). Correct treatment was marginally associated with a longer consultation time (p value for trend = 0.058). Neither in-service training in the treatment of fever nor supervision was significantly associated with correct treatment. For child health programs to improve, targeted studies are needed to understand which factors, alone or in combination, improve health care worker performance.

BACKGROUND: Good maps of malaria risk have long been recognized as an important tool for malaria control. The production of such maps relies on modelling to predict the risk for most of the map, with actual observations of malaria prevalence usually only known at a limited number of specific locations. Estimation is complicated by the fact that there is often local variation of risk that cannot be accounted for by the known covariates and because data points of measured malaria prevalence are not evenly or randomly spread across the area to be mapped. METHOD: We describe, by way of an example, a simple two-stage procedure for producing maps of predicted risk: we use logistic regression modelling to determine approximate risk on a larger scale and we employ geo-statistical ('kriging') approaches to improve prediction at a local level. Malaria prevalence in children under 10 was modelled using climatic, population and topographic variables as potential predictors. After the regression analysis, spatial dependence of the model residuals was investigated. Kriging on the residuals was used to model local variation in malaria risk over and above that which is predicted by the regression model. RESULTS: The method is illustrated by a map showing the improvement of risk prediction brought about by the second stage. The advantages and shortcomings of this approach are discussed in the context of the need for further development of methodology and software.

The global initiative to eradicate poliomyelitis is focusing on a small number of countries in Africa (Angola, Democratic Republic of the Congo, Liberia, Sierra Leone, Somalia, Sudan) and Asia (Afghanistan, Tajikistan), where progress has been hindered by armed conflict. In these countries the disintegration of health systems and difficulties of access are major obstacles to the immunization and surveillance strategies necessary for polio eradication. In such circumstances, eradication requires special endeavours, such as the negotiation of ceasefires and truces and the winning of increased direct involvement by communities. Transmission of poliovirus was interrupted during conflicts in Cambodia, Colombia, El Salvador, Peru, the Philippines, and Sri Lanka. Efforts to achieve eradication in areas of conflict have led to extra health benefits: equity in access to immunization, brought about because every child has to be reached; the revitalization and strengthening of routine immunization services through additional externally provided resources; and the establishment of disease surveillance systems. The goal of polio eradication by the end of 2000 remains attainable if supplementary immunization and surveillance can be accelerated in countries affected by conflict.

BACKGROUND: Chemotherapy with praziquantel is the current strategy of choice to control schistosomiasis. However, in view of concern about praziquantel tolerance or resistance, new drugs are needed. Artemether, a derivative of the antimalarial drug artemisinin, kills immature schistosomes of Schistosoma japonicum, and reduces the incidence of infection in field trials. Laboratory studies have also showed activity by this drug against S. mansoni. We report a randomised double-blind placebo-controlled clinical trial of artemether to prevent S. mansoni infection. METHODS: The trial was done in an area of western Côte d'Ivoire endemic for S. mansoni. 354 schoolchildren were enrolled. Stool specimens were screened over four consecutive days, followed by two mass treatments with praziquantel 4 weeks apart. All S. mansoni negative children were randomly assigned to placebo (n=151) or artemether 6 mg/kg (n=138) orally six times once every 3 weeks. Adverse events were assessed 24 h after treatment. Perceived illness episodes were recorded once a week by interviewing the children with a standardised questionnaire. 3 weeks after the final medication S. mansoni infections were assessed by screening stool samples. Blood samples were examined for Plasmodium falciparum before the first and after the last artemether treatment. FINDINGS: Oral artemether showed no adverse reactions. The group that received artemether had a significantly lower incidence of S. mansoni infection (31/128 versus 68/140, relative risk: 0.50 [95% CI 0.35-0.71], p=0.00006). The geometric mean egg output among positive children in the artemether group was significantly lower than in placebo recipients (19 vs 32 eggs/g stool, p=0.017). There was also a significant reduction in the prevalence of P. falciparum. INTERPRETATION: Oral artemether is safe and shows a prophylatic effect against S. mansoni. The use of artemether may be recommended in appropriated situations as an additional tool for more effective schistosomiasis control measures. However the application needs to be carefully assessed especially in view of the concern that it could select for resistant plasmodia.
PIP: This randomized, double-blind placebo-controlled trial examined the efficacy of oral artemether for the prevention of Schistosoma mansoni infection among 354 children from Cote d'Ivoire. Stool specimens were screened over 4 consecutive days, followed by two mass treatments with praziquantel 4 weeks apart. All S. mansoni negative children were randomly assigned to placebo (n = 151) or artemether (n = 138). An assessment after 24 hours and examination of blood samples after the 3rd week of initial administration was conducted. Findings revealed that administration of oral artemether showed no adverse reaction, with an observation of a relatively lower incidence of S. mansoni infection (31/128 vs. 68/140; relative risk, 0.50; 95% confidence interval, 0.35-0.71; p = 0.00006). In addition, the geometric mean egg output among positive children in the artemether group was significantly lower in placebo treatment (19 vs. 32 eggs/g stool; p = 0.017). Furthermore, there was a significant reduction in the prevalence of Plasmodium falciparum. The study confirmed the safety and prophylactic effect of oral artemether against S. mansoni, and recommends its use as an additional tool for a more effective schistosomiasis control measure.

This article reports the results of a peer-led HIV prevention education and condom promotion program among transport workers in Kaolack, Senegal. As part of a 2-year longitudinal follow-up study, changes in men's AIDS-related knowledge, sexual behavior, condom use, and perceived barriers to condom use were evaluated by self-reports obtained from a systematic sample of transport workers interviewed before and after intervention. In addition to men's self-reports, preintervention and postintervention data on men's sexual and condom use behavior were gathered from a sample of licensed, commercial sex workers, who cited transport workers as their primary source of clients. Significant increases in men's HIV-related knowledge, previous use of condoms (from 30.4% to 53.5%), and consistent condom use with regular sex partners were documented over the study period, as were significant declines in perceived barriers to condom use. Though men reported significantly fewer sexual encounters with casual and commercial partners at follow-up compared to baseline, these data were unreliable. Women's postintervention reports indicate that a greater proportion of clients (including, but not limited to transport workers) "always" agree to use condoms (p < .01) compared with baseline and that fewer men offer more money for unprotected sex (p < .01). However, women also report taking greater initiative in the mechanics of condom use (supplying the condom, putting it on, and taking it off) than they did prior to the intervention, and significantly (p < .05) fewer women think that most of their clients know how to use a condom. The findings indicate that the peer-mediated intervention had a positive impact on several important outcomes measured and suggest that HIV prevention efforts need to focus on male client groups despite the logistical and methodological challenges.

A decade after the first International Conference on Safe Motherhood, maternal mortality remains very high in most West African countries, even in capital cities. The detection of high risk pregnancies, known as the risk approach, during antenatal consultations has been the basis of most maternal and child health programmes over the last decade. The effectiveness of antenatal care as a tool to prevent or predict obstetric complications is being questioned more and more. In addition to the scarcity of reliable data about the predictivity of most risk factors, the quality of the screening must be questioned. The goal of this study was to assess the frequency of risk factors among a sample of pregnant women attending antenatal care in Niger and to assess the quality of the screening of those risk factors. Overall, 330 pregnant women were enrolled in the study. Each woman was examined twice: the first time by a midwife, the second time by one of the authors but without knowledge of the results of the first consultation. Fifty-five percent of pregnant women had at least one risk factor, 31% had more than one. Ninety-one percent of the risk factors were detected at interview. The following risk factors were not systematically searched for by midwives: height (48.5%), blood pressure (43.6%), glycosuria (40.6%), vaginal bleeding (38.2%), oedema (37.3%), parity (17%), age (16%), previous caesarean section (15.2%), previous stillbirth (15.2%) and previous miscarriages (14.8%). This study has shown that, in Niger, the quality of screening for risk factors during antenatal consultation is poor. In the urban settings where this study took place, lack of personnel, lack of equipment, lack of time and poor compliance by women cannot be made responsible for this situation. While screening of these risk factors continues as policy, the quality of screening must be dramatically improved.

BACKGROUND: The modes of transmission of HHV-8 are still unclear. GOAL: To evaluate the distribution and transmission of HHV-8 infection. DESIGN: Serosurvey conducted in a Cameroon hospital among 292 persons, including children (5-10 years), adolescents (15-20 years), and adults (30-40 years). Antibodies against lytic and latent antigens to HHV-8 were detected by immunofluorescence assay; antibodies against Epstein-Barr virus viral antigens were detected by enzyme-linked immunoabsorbent assay. RESULTS: The prevalence of HHV-8 antilytic antibodies remained stable and was 39.8% among children, 51.5% among adolescents, and 61.8% among adults. Epstein-Barr virus seroprevalence was high among children, and remained stable among adolescents and adults. A history of sexually transmitted diseases was an independent determinant of HHV-8 infection (adjusted odds ratio 2.47; 95% CI 1.09-4.91). CONCLUSION: The high prevalence of HHV-8 infection among children indicates nonsexual modes of transmission in Cameroon, with sexual transmission occurring among adolescents and adults.

PIP: This article highlights the crisis experienced in the beleaguered Democratic Republic of Congo (DRC). The peace talks to be conducted beginning January 20, 2000, will focus on the near-total collapse of health services and the impending humanitarian megacatastrophe in the country. The two civil wars for the past decades have resulted in an essentially bankrupt health sector and a widespread inaccessibility of basic health care. On December 1999, the UN Security Council president described the situation as the major challenge facing Africa, the UN, and the international community. Reports continue of outbreaks of epidemic infections, including vaccine-preventable diseases and hemorrhagic fevers, and unchecked diseases such AIDS, malaria, and sleeping sickness. On the other hand, the chronic malnutrition rate was reported to be as high as 31%, with some cities on the brink of famine. In addition, life expectancy has fallen by 5 years and maternal mortality has doubled, with hundreds of thousands of displaced people in refugee camps unable to sustain themselves. The meeting on January 10, 2000, will tackle the AIDS epidemic in Africa, and the DRC will be the major test of this policy, since its infection rate reached 4.35% in 1997. The withdrawal of international cooperation, which was blamed for worsening the situation, was refuted by another author stating that war and political violence killed the people.^ieng

Detection of Schistosoma haematoblum eggs in 43% of semen samples with Increased levels of eosinophil cationic protein suggests that the genital organs of men are frequently affected with schistosomiasis.
PIP: This community-based cross-sectional study was undertaken to assess the frequency of genital schistosomiasis among men in Androvakely, Madagascar, where Schistosoma haematobium is prevalent. Egg excretion and levels of eosinophil cationic protein (ECP) were measured in paired urine and semen samples obtained from 44 males eligible for the study. Findings revealed that the eggs of S. haematobium were detected in 25 urine samples (57%) and in 19 semen samples (43%). The median egg output (range) in urine was 10 eggs/ml (1-950); in semen, 3 eggs/ejaculate (1-19). Median ECP concentration in urine was 2.2 mcg/l; in semen, 109.0 mcg/l. Moreover, the concentration of ECP in urine was positively correlated with the number of eggs excreted in urine, and increased levels of seminal ECP were significantly associated with the presence of eggs in semen. The presence of eggs in 43% of the semen samples indicated that genitals were common sites for oviposition in men with S. haematobium infection. Based on the findings, a similar effect of genital schistosomiasis on HIV shedding in men, with egg deposition in the genital organs, can lead to an inflammatory response, which may then increase the viral load in semen from HIV-positive people.

PIP: This study investigates gender differences in the determinants of several schooling indicators in Conakry, Guinea, using ordered and binary probit models incorporating household-level random effects. Such indicators include grade attainment, current enrollment, and withdrawal from school. The survey, which was conducted on 1725 households, contains detailed information on a wide range of socioeconomic factors such as education, labor force activity and earnings, assets and health. Results indicate that increases in household income lead to greater investments in the schooling of girls than in the schooling of boys. Meanwhile, improvements in the education of fathers raise the schooling of both sons and daughters, while the education of mothers only has a significant impact on the schooling of daughters. These estimates show differences in maternal and paternal preferences for schooling daughters relative to sons. Therefore, the importance of gender, parental education, and household income and composition affect the education of children. However, findings also show that education for girls is unnecessary since they only need to work at home. Moreover, policies that raise household incomes will increase gender equity in schooling, which will also depend on whether and how these policies change the opportunity costs of girls and boys and the labor market returns to female and male schooling.^ieng

PIP: This article presents the publication ¿Women of the World--Francophone Africa: Laws and Policies Affecting their Reproductive Lives,¿ by Codou Bop, a Senegalese women's rights activist. This book contains a comprehensive review of the reproductive health and rights of women in Benin, Burkina Faso, Cameroon, Cote d'Ivoire, Mali, Senegal, and Chad. It provides practical and legal guidelines for rights advocates and identifies problem issues in the region. Each country was examined in terms of its political framework, sources for governing laws, customary laws and health, population and family planning policies. Across the seven nations, similar problems in restrictive abortion laws, high maternal mortality rates, high HIV/AIDS prevalence rates, low contraceptive use and the continuation of harmful traditional practices were noted. Likewise, legal status of women in the context of their right to be free from discrimination and issues affecting adolescents were examined. During the launching of the book, representatives from the featured countries were able to discuss strategies for revising laws and adopting better policies to protect the rights and welfare of women.^ieng

PIP: The conference ¿Dakar Framework for Action¿ held in Dakar, Senegal, April 26-28, 2000, declared that education is not only the key to sustainable development, but also a fundamental human right. It was stated that by 2015 all children must have access to and be able to complete primary school. The elimination of gender disparities in access to primary and secondary education by 2005 and a 50% improvement in adult literacy level by 2015 were also urged. In setting these goals, the conference reaffirmed the priorities set at the 1990 Education for All conference in Jomtien, Thailand, but extended the timetable for achieving them.^ieng

PIP: This article reports the proceedings of the meeting conducted by the International Planned Parenthood Federation (IPPF) Governing Council (GC) in Morocco. A total of 29 out of the 30 volunteer GC members attended the meeting. The activities of the first day included a visit to the Centers for Sexual and Reproductive Health and Communication Development in Rabat and Fez. It is noted that Morocco is sharing a model approach of its multi-purpose centers, which are located in densely populated areas. These centers provide reproductive health and family planning services, counseling, literacy classes, income-generating activities and legal advice on domestic violence. In the following days, discussions on administrative matters were held. In addition, the IPPF youth manifesto was presented in its final, published format, which stresses the need for IPPF youth to strengthen program activities and its financial situation. Moreover, a workshop was held to strengthen the working relationship and further communication between IPPF staff and volunteers. Issues covered included how to reach common goals and further mobilize resources.^ieng

A serological survey of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections was carried out on a random sex- and age-stratified sample of 1006 individuals aged 25-64 years in the Seychelles islands. Anti-HBc and anti-HCV antibodies were detected using commercially available enzyme-linked immunosorbent assays (ELISA), followed by a Western blot assay in the case of a positive result for anti-HCV. The age-adjusted seroprevalence of anti-HBc antibodies was 8.0% (95% CI: 6.5-9.9%) and the percentage prevalence among males/females increased from 7.0/3.1 to 19.1/13.4 in the age groups 25-34 to 55-64 years, respectively. Two men and three women were positive for anti-HCV antibodies, with an age-adjusted seroprevalence of 0.34% (95% CI: 0.1-0.8%). Two out of these five subjects who were positive for anti-HCV also had anti-HBc antibodies. The seroprevalence of anti-HBc was significantly higher in unskilled workers, persons with low education, and heavy drinkers. The age-specific seroprevalence of anti-HBc in this population-based survey, which was conducted in 1994, was approximately three times lower than in a previous patient-based survey carried out in 1979. Although there are methodological differences between the two surveys, it is likely that the substantial decrease in anti-HBc prevalence during the last 15 years may be due to significant socioeconomic development and the systematic screening of blood donors since 1981. Because hepatitis C virus infections are serious and the cost of treatment is high, the fact that the prevalence of anti-HCV antibodies is at present low should not be an argument for not screening blood donors for anti-HCV and eliminating those who are positive.
PIP: This study examined the prevalence of anti-hepatitis Bc virus (HBc) and anti-hepatitis C virus (HCV) antibodies in a random sex- and age-stratified sample of 1006 individuals aged 25-64 years in the Seychelles. The anti-HBc and anti-HCV antibodies were detected using an enzyme-linked immunosorbent assay, followed by a Western blot assay in the case of a positive result for anti-HCV antibodies. Findings revealed that the age-adjusted prevalence of anti-HBc antibodies was 10.4% and 5.8%, respectively, among men and women aged 25-63 years. The presence of anti-HBc antibodies was associated significantly with employment, educational level, and alcohol intake, marginally with economic status, and not at all with ethnic origin. 2 men and 3 women were positive for anti-HCV antibodies, with an age-adjusted seroprevalence of 0.34%. 2 out of these 5 subjects who were positive for anti-HCV antibodies were also positive for anti-HBc antibodies. The age-specific seroprevalence of anti-HBc antibodies in this population study conducted in 1994 was approximately 3 times lower than in a previous patient-based survey carried out in 1979. Although there were methodological differences between the two surveys, it is likely that the substantial decrease in the anti-HBc antibody prevalence during the last 15 years may be due to significant socioeconomic development and the systematic screening of blood donors since 1981.

The aim of this study was to describe the various methods of abortion used by women admitted to an obstetrics department in Abidjan (Ivory Coast) for abortion complications. The study was retrospective, and was based on the medical files of all 472 women admitted for abortion complications during a 3-year period (1993-1995). The introduction of plant stems into the uterus, the use of certain instruments, use of vaginal preparations, and ingestion of plants were the most common abortion methods. Seventeen maternal deaths were registered, giving a maternal mortality rate of 3.6%. A high number of previous pregnancies and the ingestion of plants to provoke abortion were factors associated with the highest risk for maternal death. Complications of "local" abortion methods accounted for a high proportion of maternal deaths.
PIP: A retrospective study was undertaken to assess the effect of various abortion practices on maternal health. The study was based on the medical files of all 472 women admitted to an obstetrics department in Abidjan, Ivory Coast, for abortion complications during a 3-year period (1993-95). The medical records of the sociodemographic and medical characteristics of women upon admission were assessed. Results demonstrated that the introduction of plant stems into the uterus was the most frequently used abortion method (31%), followed by herbal pessaries (23%) and plant infusions (20%). About 17 maternal deaths were registered, giving a maternal mortality rate of 3.6%. A high number of previous pregnancies and the ingestion of plants to provoke abortion were the factors associated with the highest risk of maternal death. Furthermore, complications resulting from local abortion methods accounted for a high proportion of maternal deaths. From the results, it was found that the potential lethal risks associated with local abortion methods were high. These results suggest that more rapid and efficient hospitalization in abortion cases and greater access to family planning would reduce the rate of maternal mortality in Ivory Coast.
