Context and objective. Toxoplamosis is a ubiquitous anthropozoonosis that occupies a large place in human and veterinary medicine. The objective of the present study was to determine the seroprevalence of toxoplasmosis in pregnant women. Methods. This was a cross sectional study involving pregnant women presenting at the laboratory of the Bossembele District Hospital, Central African Republic between June and September 2020 for toxoplasmic serology. Results. A total of 50 pregnant women were examined. The age of patients varied from 16 to 40 years. The average age was 25 ± 6 years. Primigravida (n=20; or 40%) and primiparous women (n=30; or 60%) were more preponderant. Serology was positive in 15 patients (30 %). According to sociodemographic characteristics, the seroprevalence of toxoplasmosis was higher among women aged 20 to 35 (35.2 %), women who had been pregnant three times (88.8 %) and women who lived in the Onoguia neighborhood (66.6 %). IgM was higher in patients aged 20 to 35 years (n=12), in 3rd gravida women (n=8), in multiparous (n=9) and in those living in Bodoukpa (n=6). IgG was high in pregnant women aged 20 to 35 years (n=13), in 3rd gravida women (n=7), in primiparous women (n=14) and in those living in the Bodoukpa neighbourhood (n=6). Of the patients in the study, 16 turned out to be immune to toxoplasmosis. Among 50 women, 4 experienced spontaneous abortions during previous pregnancies. Conclusion. The seroprevalence of toxoplasmosis in the present study is common. Awareness on the risks of contamination, the systematic serological monitoring and the hygiene measures should be raised during antenatal consultations. Contexte et objectif. La toxoplasmose est une anthropozoonose ubiquitaire qui occupe une large place en médecine humaine et vétérinaire. Mais les données y relatives chez la femme enceinte sont paradoxalement fragmentaires. L’objectif de cette étude était de déterminer la séroprévalence de la toxoplasmose chez les femmes enceintes. Méthodes. Il s'agissait d'une étude transversale réalisée, à la maternité de l’Hôpital du District de Bossembelé, entre juin et septembre 2020. La population d'étude était constituée de femmes enceintes se présentant au laboratoire du District pour la sérologie toxoplasmique. Résultats. Au total, les données sérologiques de 50 femmes enceintes ont été analysées. L’âge moyen était de 25 ± 6 ans (extrème 16 et 40 ans). Les femmes au premier geste (n=20 soit 40 %) et les primipares (n= 30 soit 60 %) étaient prépondérantes. La sérologie était positive chez 15 patientes (30 %). Selon les caractéristiques sociodémographiques, la séroprévalence de la toxoplasmose était plus élevée chez les femmes de 20 à 35 ans (35,2 %), les femmes ayant été enceintes trois fois (88,8 %) et les femmes qui habitent le quartier Onoguia (66,66%). Les IgM étaient plus élevées chez les patients de la tranche d’âge de 20 à 35 ans (n=12), les femmes au 3e geste (n=8), les multipares (n=9) et chez celles habitant Bodoukpa (n=6). Les IgG étaient élevées chez les femmes enceintes de 20 à 35 ans (n=13), les femmes au 3e geste (n=7), les primipares (n=14) et celles habitant le quartier Bodoukpa (n=6). Parmi les patientes étudiées, 16 (32 %) étaient immunisées contre la toxoplasmose. Des 50 femmes, 4 avaient connu un avortement spontané durant les grossesses précédentes. Conclusion. Dans la présente étude, la séroprévalence de la toxoplasmose chez la femme enceinte est très fréquente. Une sensibilisation sur les risques de contamination, une surveillance sérologique systématique et des mesures d'hygiène devraient être proposées lors des consultations prénatales.

Context and objective. Viral hepatitis B (VHB) by its evolution can lead to recovery or to a chronic form. This chronic form, a source of new contaminations, is not documented among voluntary blood donors (VBD) in Bangui and Bimbo. The present study aimed to determine the prevalence of chronic VHB among VBD in the two cities in the Central African Republic (CAR). Methods. The study carried out at the Bangui National Blood Transfusion Center was retrospective and focused on serological control data from VBD from Bangui, capital of CAR and Bimbo. The exhaustive sampling is from July 2013 to December 2019. A VBD carries a chronic infection if the VHB surface antigen persists for more than six months. Results. Serological control data from 702 VBD aged 18 to 62 years were analyzed. Male sex predominated at inclusion (n = 598). The prevalence of chronic VHB was 70.5 %. This prevalence was higher among young VBD aged 25 to 34 years (30.4 %), the male gender (58.4 %) and VBD residing in Bangui (61.2 %). The chronic form was significantly associated with young age (18 to 44 years) and male sex (p< 5%). Co-infection with HIV and hepatitis C was found in 5.5 % of cases (39/702). Conclusion. The prevalence of chronic VHB is very high in VBD from Bangui and Bimbo. The chronic form was significantly associated with age and sex. Free viral load and antiviral treatment are prospects to be implemented.

Background Breast cancer (BC) is the most common cancer in women worldwide and leading cause of cancer deaths indeveloping countries. There is very limited data on BC in the Central African Republic. The purpose of this study was to describe the epidemiological and histopathological characteristics of BC in Bangui. Methods This retrospective study reviewed cancer data registries and medical records from the Pathology Unit of the National Laboratory in Bangui and the General Surgery and Gyneacology service from 2003 to 2015. A questionnaire was designed to collect information and data was analysed using descriptive and inferential statistical methods. Results In total, 174 cases of BC were recorded, with an average annual frequency of13.4 cases per year. The age of the women at diagnosis varied from 16 to 90 years with a median of 45.5 years and InterQuartile range (IQR) 18 years. The age group of 45–54 years represented the majority of the study population (n = 51, 29.3%).About 25.9%ofthe patients were non-educated and 85.6% lived in cities. Over 48 % of the women were housewives with a moderate economic status (n = 99, 56.9%). Sixty nine percent of the specimens received at the pathology unit were pieces of breast tumour. Invasive ductal carcinoma (n = 113, 64.9%) was the main histological form and most of the tumours were of Grade III (n = 14, 46.7%). The only imaging assessment was ultrasound performed in (n = 53, 30.4%) women. Surgery was performed in (n = 166, 95.4%) patients, while (n = 159, 91.4%) received complementary chemotherapy. At the end of the study, 84.5%of the cases had died, 12.1% were alive and 3.4% were considered “lost to follow-up”. Conclusion BC is an important public health problem and affected most of the younger Central African women. Epidemiological and histological characteristics are more or less common to those described other developing countries. It is imperative to improve the awareness of health care institutions and women on the burden of BC, to carry out early screening of BC, and to strengthen the capacity of women’s health care system.

Background Breast cancer (breast Ca) is recognised as a major public health problem in the world. Data on reproductive factors associated with breast Ca in the Central African Republic (CAR) is very limited. This study aimed to identify reproductive variables as risk factors for breast Ca in CAR women. Methods A case–control study was conducted among 174 cases of breast Ca confirmed at the Pathology Unit of the National Laboratory in Bangui between 2003 and 2015 and 348 age-matched controls. Data collection tools included a questionnaire, interviews and a review of medical records of patients. Data were analysed using SPSS software version 20. Odd ratios and 95% confidence intervals (CI) for the likelihood of developing breast Ca were obtained using unconditional logistic regression. Results In total, 522 women with a mean age of 45.8 (SD = 13.4) years were enrolled. Women with breast Ca were more likely to have attained little or no education (AOR = 11.23, CI: 4.65–27.14 and AOR = 2.40, CI: 1.15–4.99), to be married (AOR = 2.09, CI: 1.18–3.71), to have had an abortion (AOR = 5.41, CI: 3.47–8.44), and to be nulliparous (AOR = 1.98, CI: 1.12–3.49). Decreased odds of breast Ca were associated with being employed (AOR = 0.32, CI: 0.19–0.56), living in urban areas (AOR = 0.16, CI: 0.07–0.37), late menarche (AOR = 0.18, CI: 0.07–0.44), regular menstrual cycles (AOR = 0.44, CI: 0.23–0.81), term pregnancy (AOR = 0.26, CI: 0.13–0.50) and hormonal contraceptive use (AOR = 0.62, CI: 0.41–0.93). Conclusion Breast Ca risk factors in CAR did not appear to be significantly different from that observed in other populations. This study highlighted the risk factors of breast Ca in women living in Bangui to inform appropriate control measures.

Breast cancer is recognized as a major public health problem in developing countries; however, there is very little evidence of behavioral factors associated with breast cancer risk. This study was conducted to identify lifestyles as risk factors for breast cancer among Central African women. A case-control study was conducted with 174 cases confirmed histologically by the pathology unit of the National Laboratory and 348 age-matched controls. Data collection tools included a questionnaire with interviews and medical records of patients. Data were analyzed using SPSS software version 20. Odd ratio (OR) and 95% confidence intervals (95% CI) were obtained by unconditional logistic regression. In total, 522 women were studied with a mean age of 45.8 (SD = 13.4) years. By unconditional logistic regression model, women with breast cancer were more likely to have attained illiterate and elementary education level [11.23 (95% CI, 4.65-27.14) and 2.40 (95% CI, 1.15-4.99)], married [2.09 (95% CI, 1.18-3.71)], positive family history [2.31 (95% CI, 1.36-3.91)], radiation exposure [8.21 (95% CI, 5.04-13.38)], consumption charcuterie [10.82 (95% CI, 2.39-48.90)], fresh fish consumption [4.26 (95% CI, 1.56-11.65)], groundnut consumption [6.46 (95% CI, 2.57-16.27)], soybean consumption [16.74 (95% CI, 8.03-39.84)], alcohol [2.53 (95% CI, 1.39-4.60)], habit of keeping money in bras[3.57 (95% CI, 2.24-5.69)], overweight [5.36 (95% CI, 4.46-24.57)] and obesity [3.11(95% CI, 2.39-20.42)]. However, decreased risk of breast cancer was associated with being employed [0.32 (95% CI, 0.19-0.56)], urban residence [0.16 (95% CI, 0.07-0.37)], groundnut oil consumption [0.05 (95% CI, 0.02-0.14)], wine consumption [0.16 (95% CI, 0.09-0.26)], non habit of keeping cell phone in bras [0.56 (95% CI, 0.35-0.89)] and physical activity [0.71(95% CI, 0.14-0.84)]. The study showed that little or no education, marriage, positive family history of cancer, radiation exposure, charcuterie, fresh fish, groundnut, soybean, alcohol, habit of keeping money in bras, overweight and obesity were associated with breast cancer risk among Central African women living in Bangui. Women living in Bangui should be more cautious on the behavioral risk associated with breast cancer.

Background Breast cancer is recognised as a major public health problem in developing countries; however, there is very limited evidence about its epidemiology in the Central African Republic. The aim of this study was to investigate the epidemiological and histopathological characteristics of breast cancer in Bangui. Methods This is a retrospective study based on the data collected from pathological anatomy records from 2003 to 2015 in Bangui. A questionnaire was designed to collect information and data was analysed using descriptive and inferential statistical methods. Results The mean age was 45.83 (SD = 13.5) years. The age group of 45–54 years represented the majority of the study population (29.3%). Over 69.5% of the women were housewives with a moderate economic status (56.9%). Less than 14% of the study population had a level of academic degree and 85.6% lived in cities. The breast cancer prevalence was 15.27%. The age-standardized incidence and death by world population (ASW) were 11.19/100,000 and 9.97/100,000 respectively. 50–54 years were most affected. Left breast cancer is mainly common and the time between first symptoms and consultation is more than 48 months. Most (69%) of the samples analysed were lumpectomy. The most common morphology of breast cancer was invasive ductal carcinoma (64.9%). Scarff Bloom Richardson III was the main grade in both common pathological types, but their proportion showed no significant increase along with time (χ2 = 7.06, p = 0.54). Invasion of regional lymph node differed significantly among the pathological type of breast cancer (χ2 = 24.6, p = 0.02). Surgery and chemotherapy were appropriate treatment yet 84.5% of the cases died. Conclusion The findings of this study showed that breast cancer is common and mostly affected women. Epidemiological trends are more or less common to those of developing countries with a predominance of invasive ductal carcinoma. However, most of the women studied live in an urban area and developed the disease in advanced stage. The establishment of an appropriate framework will effectively contribute to promoting the early detection and reducing the incidence of this disease in the population.

Breast cancer is the leading cause of cancer deaths among women worldwide. High breast cancer mortality has been attributed to lack of public awareness of the disease. Little is known about the level of knowledge of breast cancer in Central African Republic. This study aimed to investigate the knowledge of health professionals on breast cancer.This cross-sectional study was conducted among 158 health professionals (27 medical; 131 paramedical) in 17 hospitals in Bangui using a self-administered questionnaire. Descriptive statistical analysis, Person's χ 2 test and ANOVA were applied to examine associations between variables with0.05 being considered significant.Data analyzed using SPSS version 20 indicates that average knowledge about breast cancer perception of the entire population was 47.6%, diagnosis method 45.5%, treatment 34.3% and risk factors 23.8%. Most respondents (65.8%) agreed that breast cancer is important in the Central African Republic and that family history is a risk factor (44.3%). Clinical assessments and mammography were considered most suitable diagnostic methods, and surgery as the best treatment. The knowledge level was significantly higher among medical than paramedical staff with regard to risk factors, diagnosis and treatment. However the trainee group had very high significant differences of knowledge compared with all other groups.There is a very urgent need to update the various training programs for these professionals, with recommendations of retraining. Health authorities must create suitable structures for the overall management of cancer observed as a serious public health problem.

Introduction: This cross-sectional study was conducted among 73 healthcare workers in two laboratories in Bangui, using self administered questionnaire and scale grid to get information on knowledge and practice of management biomedical waste (BMW). Methods: Data were analyzed using SPSS software (version 20). Fisher chi-square test was used to investigate whether distributions of categorical variables differ from one another. Results: Findings from this study shows that; a gap in legal framework on BMW. Seventy percent of waste generated was infectious. Segregation and color coding was inappropriate. Only 29% of the services used safety boxes. Transport of BW is manual. About 64 % of respondents have not received training on BMW. 44 of 73 (60%) didn’t know certain diseases related to poor waste management and transmission routes. The surface technicians had significantly better knowledge about tetanus vaccine than the medical-technical staff (χ2 = 4.976, p=0.047). They had also a significantly higher risk of exposure to accidents due to waste handling than medical-technical (χ2=10.276, p=0.009). The 30-39 age group had a significantly higher risk of exposure to accidents related to the BMW compared to other ages groups (χ2=11.206, p=0.026).The National Laboratory personal has significantly higher knowledge about BCG and Meningitis vaccine than the Laboratory of Community Hospital personal (χ2=10.954, p=0.002 and χ2=4.304, p=0.05). Conclusion: BMW was poor. Collaboration between the City Hall and sanitation services with the support of partners will greatly reduce the risk of exposure faced by laboratory personnel and the population.
