Complications of clandestine abortions: a cross-sectional study at the Provincial General Hospital of Kananga in the Democratic Republic of Congo

Introduction: the complications of clandestine abortions are formidable throughout the world, particularly in Africa. This study aims to determine the epidemiological and therapeutic profile of the complications of clandestine abortions in the gynecology service of the Provincial Hospital of Kananga. Methods: this is a cross-sectional study conducted from the medical records of pregnant women who experienced the complications of clandestine abortions in the gynecology department of the Provincial Hospital of Kananga from January 01, 2015, to December 31, 2019. It is based on the no probabilistic sampling of suitability. We recorded 38 cases of 58 patients. Results: the frequency of complications of clandestine abortions is 65.51% with an average age of pregnant women of 27.86 (SD 3.23) years and 70% of pregnant women under 30 years old, nulliparity was more concerned in 34.21% (n=13). Pupil students and unemployed are more affected in 55.26% (n=21). Cervical dilation and curettage practiced by nurses led to more complications from clandestine abortions in 69.07% (n=26). Incomplete abortions are the complications most encountered in 1 case out of 3. The aspiration-curettage is established in 1 out of 3 cases, and the mortality rate linked to complications of clandestine abortion was 21.05% (n=8). Conclusion: complications of clandestine abortions constitute a real public health problem in the town of Kananga, incomplete abortions are most encountered and the mortality rate linked to these complications is serious.

Profil épidémiologique et mortalité due à la tuberculose dans la zone de Santé de Kamina, Province du Haut-Lomami, en Démocratique du Congo / Epidemiological profile and deaths related to TB disease in the Kamina´s Health Zone, Haut-Lomami Province, Democratic Republic of the Congo

Introduction: Était de décrire le profil épidémiologique, clinique et évolutif des patients tuberculeux suivis dans le milieu urbano-rural de Kaminaen République Démocratique du Congo (RDC). Méthodes: il s´agit d´une étude transversale par analyse rétrospective de dossiers des patients suivis pour tuberculose sur une période allant du 1er Janvier 2018 au 31 Décembre 2021. Résultats: sur un total de 612 échantillons analysés, 216 cas de tuberculose ont été confirmés par le laboratoire, soit une fréquence de 35,3 %. Notre échantillon était constitué de 138 hommes et 78 femmes, soit un sex-ratio de 1,77. L´âge moyen était de 35,37±18,14 années. La majorité des patients était dans la tranche d´âge comprise entre 21-40 ans. La profession libérale représentait 94,4 % de notre effectif, soit 204 patients. Il y a eu 63,4% des patients souffraient d´une tuberculose pulmonaire dont 70,9 % était guéris. La sérologie VIH était positive chez 6 patients, soit un taux de séroprévalence VIH de 2,77 %. Au total, 27 malades sont décédés sur les 612, soit un taux de mortalité de 4,41 %. C´est la tranche d´âge de malades ages de plus de 60 ans qui a connu une mortalitéélévée, soit 5 cas sur 20 (25 %), suivie de celle des malades ages de moins de 20 ans, 11 cas sur 49 (22,4 %). D´autre part, le résultat a montré un taux de mortalité plus élévé chez les tuberculeux séropositif, 33,3 %, contre 11.9 % chez les séronégatifs. Conclusion: ce rapport montre un taux élevé de tuberculose dans la zone de santé de Kamina ; il confirme le fait que la TB est endémique dans la région. Il est nécessaire d'améliorer les conditions de vie de la population et le système de santé local en ce qui concerne la prévention et la gestion de la TB afin de réduire sa morbi-mortalité.

Introduction: the purpose of this study was to describe the epidemiological, clinical and evolutionary profile of patients with tuberculosis followed in the urban-rural area of Kamina, Democratic Republic of the Congo (DRC). Methods: we conducted a cross-sectional study based on a retrospective analysis of the medical records of patients followed for tuberculosis over the period January 1, 2018 -December 31, 2021. Results: out of 612 samples analysed, 216 cases had received lab confirmation of tuberculosis, reflecting a rate of 35.3%. Our sample consisted of 78 women and 138 men (sex ratio 1.77). The average age of patients was 35,37±18.14 years. The majority of patients were in the age range 21-40 years. Self-employed people accounted for 94.4% of our workforce (204 patients); 63.4% of patients suffered from pulmonary tuberculosis, 70.9% of whom were cured. Serology test for HIV was positive in 6 patients (i.e. an HIV seroprevalence rate of 2.77%). In total, 27 patients out of 612 died, (i.e. a mortality rate of 4.41%). Patients aged over 60 had higher mortality rates (5 out of 20 cases; 25%), followed by patients under 20 (11 out of 49 cases; 22.4%). On the other hand, our results showed a higher mortality rate among HIV-positive patients with tuberculosis (33.3%, compared to 11.9% among HIV-negative patients). Conclusion: this study shows a high rate of tuberculosis in the Kamina health zone, confirming the fact that TB is endemic in the region. There is a need to improve the living conditions of the population and the local health system with regard to the prevention and management of TB in order to reduce morbidity and mortality

Change in prevalence and pattern of peptic ulcer disease in the Northern Savannah of Nigeria: An endoscopic study

Background: Peptic ulcer disease (PUD) is common worldwide. Its incidence and prevalence have been declining in recent years in developed countries, and a similar trend has been observed in many parts of Africa including Nigeria. Aim: This study aimed to provide an endoscopic update on PUD in the Northern Savannah of Nigeria and compare with past reports from the region and recent reports from Nigeria, Africa, and the rest of the world. Methods: Upper gastrointestinal endoscopy records of consecutive patients diagnosed with PUD between January 2014 and September 2022 at an endoscopy unit of a tertiary institution in North West Nigeria were retrieved and demographic data, types of peptic ulcer, and their characteristics were extracted and analyzed. Results: Over a 9 year period, 171/1958 (8.7%) patients were diagnosed with PUD: mean age 48.8 years (range 14­85), 68.4% male, and 70% >40 years. 59.6% were gastric ulcers (GU), 31.6% duodenal ulcers (DU), and 8.8% were both. The mean age of patients with GU was slightly higher than those with DU (49.9 years vs. 46.6 years, P = 0.29); patients aged 40 years significantly more GU than DU (74.6% vs. 54.7%, P = 0.016). There were no significant gender differences between GU and DU. Conclusion: The prevalence and pattern of PUD in Northern Savannah of Nigeria have changed ­ patients were predominantly male and older, and GU predominated.

A review of the recent advances on Lassa fever with special reference to molecular epidemiology and progress in vaccine development

Lassa fever, a viral hemorrhagic fever caused by the Lassa virus (LASV), is endemic in West Africa and is associated with high morbidity and mortality. At least three of the four proposed seven lineages of LASV are found in Nigeria, where the multimammate rat, Mastomys natalensis, serves as the primary reservoir. Endemic countries report approximately 200,000 infections and 5,000 deaths annually, with Nigeria experiencing thousands of infections and hundreds of deaths including healthcare workers. The aim of this review is to provide scientific information for better understanding of the evolutionary biology, molecular epidemiology, pathogenesis, diagnosis, and prevention of Lassa fever in Nigeria and other endemic regions worldwide, which can lead to improved control efforts and reduce morbidity and mortality from recurrent epidemics. To achieve this aim, observational studies such as case series, cross-sectional and cohort studies published between December 2017 and September 2022 were searched for on various online databases including Google Scholar, Africa Journals Online (AJOL), Research Gates, PubMed, PMIC, NCDC, and WHO websites. Although the origin and evolutionary history, and the transmission dynamics of Lassa virus have been revealed through recent molecular epidemiological studies, the factors that drive the evolution of the virus remain unclear. Genetic changes in the viral genome may have enabled the virus to adapt to humans. Diagnosis of Lassa fever has also advanced from basic serological tests to more sophisticated methods such as quantitative real time polymerase chain reaction (qRT-PCR) and sequencing, which are particularly useful for identifying outbreak strains. Several vaccines, including recombinant vesicular stomatitis virus (rVSV), virus-like particle (VLP), and DNA-based vaccines, have shown promise in animal models and some have progressed to phase 2 clinical trials. Preventing and controlling Lassa fever is critical to safeguard the health and well-being of affected communities. Effective measures such as rodent control, improved sanitation, and early detection and isolation of infected individuals are essential for reducing transmission. Ongoing research into the genetic and ecological factors that drive the evolution of Lassa virus is necessary to reduce the impacts of Lassa fever

La fièvre de Lassa, une fièvre hémorragique virale causée par le virus de Lassa (LASV), est endémique en Afrique de l'Ouest et est associée à une morbidité et une mortalité élevées. Au moins trois des quatre lignées proposées de LASV se trouvent au Nigeria, où le rat multimammaire, Mastomys natalensis, sert de réservoir principal. Les pays endémiques signalent environ 200,000 infections et 5,000 décès par an, le Nigéria connaissant des milliers d'infections et des centaines de décès, y compris des travailleurs de la santé. L'objectif de cette revue est de fournir des informations scientifiques pour une meilleure compréhension de la biologie évolutive, de l'épidémiologie moléculaire, de la pathogenèse, du diagnostic et de la prévention de la fièvre de Lassa au Nigeria et dans d'autres régions endémiques du monde, ce qui peut conduire à des efforts de contrôle améliorés et réduire la morbidité et la mortalité des épidémies récurrentes. Pour atteindre cet objectif, des études observationnelles telles que des séries de cas, des études transversales et de cohorte publiées entre décembre 2017 et septembre 2022 ont été recherchées sur diverses bases de données en ligne, notamment Google Scholar, Africa Journals Online (AJOL), Research Gate, PubMed, PMIC, Sites Web du NCDC et de l'OMS. Bien que l'origine et l'histoire évolutive, ainsi que la dynamique de transmission du virus de Lassa aient été révélées par des études épidémiologiques moléculaires récentes, les facteurs qui déterminent l'évolution du virus restent flous. Des modifications génétiques du génome viral pourraient avoir permis au virus de s'adapter à l'homme. Le diagnostic de la fièvre de Lassa est également passé des tests sérologiques de base à des méthodes plus sophistiquées telles que la réaction quantitative en chaîne par polymérase en temps réel (qRTPCR) et le séquençage, qui sont particulièrement utiles pour identifier les souches épidémiques. Plusieurs vaccins, y compris le virus recombinant de la stomatite vésiculeuse (rVSV), les particules pseudo-virales (VLP) et les vaccins à base d'ADN, se sont révélés prometteurs dans des modèles animaux et certains ont progressé vers des essais cliniques de phase 2. La prévention et le contrôle de la fièvre de Lassa sont essentiels pour préserver la santé et le bien-être des communautés touchées. Des mesures efficaces telles que le contrôle des rongeurs, l'amélioration de l'assainissement et la détection et l'isolement précoces des personnes infectées sont essentielles pour réduire la transmission. Des recherches continues sur les facteurs génétiques et écologiques qui déterminent l'évolution du virus de Lassa sont nécessaires pour réduire les impacts de la fièvre de Lassa.

Il s'agit d'une étude transversale, monocentrique et descriptive, durant 12 mois, incluant les patients âgés d'au moins 18 ans admis en réanimation polyvalente pour un sepsis ou choc septique. Les variables épidémiologiques, cliniques, bactériologiques et évolutives ont été analysées avec Excel 2019. Résultats. 56 patients ont été retenus (20,7%). Leur âge moyen était de 43,1 ± 17,9 ans (extrêmes de 18 et 84 ans), avec 66,1% des hommes. Le foyer infectieux initial était péritonéal (64,3 %). À l'admission, le nombre médian de défaillances d'organes par patient était de trois (maximum 5). Les défaillances rénale (71,4%), hépatique (69,6%) et hémodynamique (62,5%) étaient les plus représentées. Le taux de réalisation du bilan bactériologique était de 35,7% : hémoculture (10,7%), uroculture (14,3%), porte d'entrée infectieuse (7,1%). La durée d'hospitalisation des patients sortis vivants était de 8,1 ± 6,3 jours (extrêmes de 2 et 31 jours). Le taux de mortalité était de 57,1%. Les décès survenaient au-delà de 24 h d'hospitalisation (75%), chez des patients avec comorbidités (65,6%), porte d'entrée péritonéale (59,4%), et défaillances hémodynamique (81,2%) et rénale (75%). Conclusion. Les prévalences du sepsis et du choc septique dans notre série sont superposables à celles de la littérature. Le taux de réalisation des bilans bactériologiques reste faible. La mortalité du sepsis demeure très élevée.

Introduction. No accurate data on sepsis and septic shock in intensive care unit (ICU) in the Republic of Congo are available. The aim of the study was to describe the course of patients with sepsis and/or septic shock in the polyvalent ICU of the University Teaching Hospital of Brazzaville. Patients and methods. This was a cross-sectional, monocentric and descriptive study, lasting 12 months, including patients aged at least 18 years admitted to ICU for sepsis or septic shock. The clinical presentation, the bacteriological findings and the outcome were analyzed with Excel 2019. Results. 56 patients were selected (20.7%). The average age was 43.1 ± 17.9 years (extremes 18 and 84 years), with 66.1% of men. The initial infection was peritoneal (64.3%). At admission, the median number of organ failures per patient was three (maximum 5). Renal (71.4%), hepatic (69.6%) and hemodynamic (62.5%) failures were the most common. Bacteriological assessment rate was 35.7%: blood culture (10.7%), urine culture (14.3%). The duration of hospitalization of alive patients was 8.1 ± 6.3 days (extremes 2 and 31 days). The mortality rate was 57.1%. Deaths occurred beyond 24 hours of hospitalization (75%), in patients with comorbidities (65.6%), peritonitis (59.4%), hemodynamic (81.2%) and renal (75%) failures. Conclusion. The prevalence of sepsis and septic shock in our study is comparable to other published series. The bacteriological assessments rate is still low. The mortality is very high.

Introduction. Les hémopathies malignes sont des proliférations anormales et anarchiques de cellules hématopoïétiques à point de départ médullaire ou périphérique. Notre étude qui avait pour objectif de faire le bilan de la prise en charge des hémopathies malignes au Centre national d'oncologie médical et de radiothérapie Alassane Ouattara. Méthodes. Il s'agissait d'une étude rétrospective descriptive d'une durée de 2 ans 3 mois allant du 1er janvier 2018 au 31 Mars 2020 portant sur 80 dossiers de malades porteurs d'hémopathies malignes et prise en charge dans le centre. Résultats. Notre étude a permis de recenser 2,2% d'hémopathies malignes sur les 3650 cas de pathologies cancéreuses recensées au CNRAO, soit une incidence 26,66 cas/an avec un sex-ratio 1,2. Les syndromes lymphoprolifératifs (SLP) sont les plus fréquents (96,25 %), sous trois principales formes: lymphomes malins non hodgkiniens (LMNH) non Burkitt (51,25%), leucémie myéloïde chronique (20%) et le myélome multiple (16,25%). Les LMNH représentent 51,25% des HM recensées avec 41,46 % de lymphomes de haut grade de malignité. La chimiothérapie était de mise chez tous nos patients. Ainsi sur 41 cas de LMNH, seulement 12 (29,27%) ont bénéficié du protocole R-CHOP. On notait 46,34% de réponse complète. Dans notre étude, le LH représentait 8,75% il était traité à 71,43% avec le protocole ABVD avec une réponse complète chez 6 patients. 37,5% des patients porteurs de leucémie myéloïde chronique ont reçu le Rituximab; ils ont été traités par les protocoles COP (31,25%), CHOP (31,25%), RCVP (12,5%) et R-CHOP (25%). La réponse thérapeutique était complète à 68,75%. Le protocole utilisé dans le traitement du myélome multiple a été le VMCD-REV à 76,92% avec pour réponse thérapeutique complète chez 6 patients, 3 réponses partielles et 4 en cours de traitement. Conclusion. Les SLP qui sont les plus fréquents des HM avec trois principales formes: LMNH non Burkitt, leucémie myéloïde chronique et myélome multiple. Nous avons cependant des difficultés quant à la mise en route de la chimiothérapie.

Introduction. Hematologic neoplasms are abnormal and anarchic proliferations of hematopoietic cells with a medullary or peripheral starting point. Our study aimed to report the management of hematological malignancies at the Centre National d'Oncologie Médicale et de Radiothérapie Alassane Ouattara (CNRAO). Methods. This was a descriptive retrospective study lasting 2 years 3 months from January 1st, 2018 to March 31st, 2020 concerning 80 patients with hematologic neoplasms who were managed in the CNRAO. Results. Hematologic neoplasms represented 2.2% of cancers (80/3650) at CNRAO, giving an annual incidence of 26.66 cases. The sex ratio was 1.2. Lymphoproliferative syndromes were the most common subgroups (96.25%). These were mainly non-Burkitt non Hodgkin lymphoma (51.25%), high grade lymphomas (41.46%), chronic lymphocytic lymphoma (20%) and multiple myeloma (16.25%). Chemotherapy was administered to all patients. Among 41 cases of non-Hodgkin lymphoma, 12 (29.27%) benefited from the R-CHOP protocol and full response was observed in 46.34% of them. We found 7 patients with Hodgkin lymphoma (8.75%) and the ABVD protocol was used for 6 cases (71.43%). Six out of these seven patients were in complete response. Among the 16 patients with chronic lymphocytic leukemia, 6 (37.5%) received Rituximab. The distribution of the patients with chronic lymphocytic leukemia was as follows: COP 31.25%, CHOP 31.25%, RCVP 12.5% and R-CHOP 25% and 68.75% had full response. The most common treatment protocol for multiple myeloma was VMCD-REV (76.92%). Six patients had complete response, 3 had partial response and 4 were in the course of treatment. Conclusion. In our practice, hematologic neoplasms are mainly lymphoproliferative syndromes and the most common varieties are non-Burkitt non Hodgkin lymphoma, high grade lymphomas, chronic lymphocytic lymphoma and multiple myeloma. We have difficulties in getting chemotherapy started.

Emergency centre patients in the Democratic Republic of Congo: Some epidemiological and clinical aspects at Beni General Referral Hospital

Introduction: Little information is available regarding the characteristics of patients attending the emergency centre (EC) in the Democratic Republic of Congo. This study aims to provide some epidemiological and clinical aspects of patients admitted to the emergency centre at Beni General Referral Hospital. Methodology: For a year, from January to December 2021, a cross-sectional study was conducted. Data regarding patients' characteristics, admission modality, stay duration, reason for admission, and discharge modality was anonymously collected from patients' registers. A descriptive analysis was done with Epi-Info 7. Result: A total of 1404 patients were admitted to the EC, with a male-to-female ratio of 1.2 to 1. The age group below 18 years accounted for 35.4%. Most of the patients (75.7%) originated from urban areas. In 83% of cases, there was no recommendation from another medical facility for EC admission. The most common reasons for admission are non-traumatic gathering on top of neuropsychiatric and non-specific symptoms. Road traffic accidents are the most frequent causes of trauma symptoms. Few patients (14.7%) spent less than 12 hours in the EC. Globally, 7.3% of patients admitted to the EC were discharged after being managed, and 89% were transferred to different wards. The intra-emergency centre mortality rate was 11.8% among admitted patients in the ER at Beni General Referral Hospital. Conclusion: This epidemiology database underlines the need for developing globalizing and multi-sectoral interventions (diagnosis, therapeutic strategy, organization, health program, or health policies) in the perspective of bringing change and/or taking action in the Democratic Republic of Congo's emergency medical system.

Thoracic trauma in national hospital Abuja, Nigeria: The epidemiology, injury severity and initial management options

Background: Trauma is the leading cause of death in individuals between the ages of 1 and 44 years and it is the third commonest cause of death regardless of age. Thoracic trauma is a relatively common cause of preventable death among trauma patients. The spectrum of injuries after blunt chest trauma presents a challenging problem to the emergency physician. This study is intended to discuss the epidemiology, severity and initial management strategies in chest trauma patients, in a low income country. Methods: A cross sectional retrospective study among chest trauma patients seen in the emergency room of National Hospital Trauma Centre, Abuja, Nigeria, from January 2015 to December 2017. Relevant patients' information was retrieved from the trauma registry kept in the trauma centre. Data processing and analysis was done using statistical package for social sciences (SPSS) version 24. Test of significance was done where applicable using chi square and student t test, using p value less than 0.05 as significant. Results are presented in tables and figures. Results: A total of 637 patients, male to female ratio of 3.6 and mean age of 34.18 ± 11.34 were enrolled into the study. The most common mechanisms of injury were MVC (54.6%) and assault (23.5%). Blunt injuries were 3.5 times more frequent than the penetrating injuries. The RTS of 12 (76.3%) and the ISS of 1-15 category (52.3%) were the most common scores. Up to 98% of patients were managed non-operatively. Recovery rate was high (89%) with relatively low mortality rate of 4.2%. Conclusion: Majority of thoracic trauma can be managed effectively by employing simple, non-operative procedures such as needle decompression and chest tube insertion. Efforts should be made to include these procedures in the skill set of every medical officer working in the emergency room, particularly in low and middle income countries where there is paucity of emergency physicians.

The current monkeypox outbreak is a public health emergency of international concern and is coming in the wake of the SARS-CoV-2 pandemic. Human monkeypox is a viral zoonotic infection caused by monkeypox virus, an enveloped double-stranded DNA virus of the genus Orthopoxvirus and family Poxviridae that also contain smallpox, cowpox, Orf, and vaccinia viruses. Online databases including PubMed, Google Scholar and Web of Science were searched to obtain relevant publications on the epidemiology, treatment, vaccines and the economic impacts of the current monkeypox (Mpox) outbreak.

Factors associated with COVID-19 fatality among patients admitted in Mashonaland West Province, Zimbabwe 2020-2022: a secondary data analysis

Introduction: approximately 15% of COVID-19 patients develop symptoms necessitating admission. From 2020 to 2022, Mashonaland West Province had an institutional case fatality rate of 23% against a national rate of 7%. Therefore, we evaluated the COVID-19 admissions in the province to determine the factors associated with COVID-19 mortality. Methods: we conducted an analytical cross-sectional study based on secondary data from isolation centers across the province using all 672 death audit forms and patient records. We obtained data on patient demographics, signs and symptoms, clinical management and oxygen therapy administered, among other things. Data were entered into an electronic form and imported into Epi-info 7 for analysis bivariate and multivariate was conducted. Results: we found that being an older man, aOR 1.04 (1.03-1.05), who had diabetes aOR 6.0 (95% CI: 3.8-9.2) and hypertension aOR 4.5 (95% CI: 2.8-6.5) were independent risk factors. Patients put on dexamethasone aOR 2.4 (95% CI: 1.6-3.4) and heparin/clexane aOR 1.6 (95% CI: 1.1-2.2) had a higher mortality risk. However, vitamin C aOR 0.48 (95% CI: 0.31-0.71) and oxygen therapy aOR 0.14 (95% CI: 0.10-0.19) and being pregnant aOR 0.06 (95% CI: 0.02-0.14) were protective. Conclusion: mortality risk increased in older male patients with comorbidities and with those on dexamethasone and heparin therapy. Oxygen therapy and vitamin C were protective. There is a need to conduct further study of the source of these variations in risk across patients to establish the true impact of differences in individuals' mortality.

Epidemiology of hepatitis B virus infection among pregnant women in Lubumbashi, Democratic Republic of Congo: prevalence, risk factors, and genotype distribution

Background Mother-to-child transmission (MTCT) of hepatitis B virus (HBV) is a significant public health problem. Most children under five years living with HBV in endemic areas like sub-Slivingan Africa. Vertical transmission is considered the main newborn's route of contamination, which leads in 90% of cases to the chronic stage of the disease. Objectives To determine the seroprevalence and identify risk factors of carrying hepatitis B surface Antigen (HBsAg) in pregnant women, assess biochemical parameters, and study the distribution of HBV genotypes among infected pregnant women in Lubumbashi. Methods This was a cross-sectional descriptive and experimental study in which 1711 pregnant women were recruited. The study took place in the hospital Jason Sendwe of Lubumbashi. A pre-established epidemiological survey form was used to collect data from the study population. Results The seroprevalence of HBV among pregnant women was 4.4%. Blood transfusion and unprotected sex have been associated with the risk of carrying HBsAg. Increased levels of bilirubin and transaminases were observed. The genotypes E (59.4%), A (40.6%), and a few drug resistance mutations were identified in the study population. Conclusion With an HBV seroprevalence of 4.4%, MTCT of HBV remains a public health concern in Lubumbashi. This result highlights the vital role of HBV screening in pregnant women and newborns and early HBV vaccination. In addition, the obtained HBV genotyping data could help better understand the local epidemiology of the disease, predict the outcome of the Antiviral therapy, and develop a mapping of HBV genotypes in Lubumbashi.

Aspects épidémiologiques et thérapeutiques de la maladie de Kawasaki à Libreville de 2014 à 2021

Introduction.Kawasaki disease (KD) is an acute multi-systemic vasculitis of young children and infants. It is the first cause of acquired cardiac disease in children and remains poorly described in Gabon. We therefore wanted to describe the epidemiological and therapeutic aspects of this disease in two hospitals in Libreville. Patients and methods.We conducted a retrospective, descriptive study from 2014 to 2021 at the Akanda University Hospital and the El Rapha polyclinic in Libreville. All records of patients hospitalised in paediatrics for MK were included. Results.Thirty three cases of MK were retrieved, giving ahospital prevalence of0.6%. The mean age of patients was 20.4 months, the proportion of patients <18 months was 60.6% and the sex ratio was 1.7. The symptoms were observed mainly during the dry season (69.7%). Fever (100%), conjunctivitis (78.8%) and desquamation (72.7%) were the main reasons for consultation. In 24.2% of cases, a traditional medicine was administered. The average time between the onset of symptoms and hospitalization was 11 days. Once hospitalized, the diagnosis of MK was evoked within an average of 3 days. The typical form was observed in 57.6% of cases. In 100% of cases, the hemoglobin level was <12g/dl and the CRP was >15mg/l. Echocardiography was abnormal in 5 patients. Acetylsalicylic acid was the only treatment with a mean time to apyrexia of 3 days after administration. No deaths were recorded. Conclusion:the MK is relatively present in Libreville. It is important to mention it in the event of a fever of more than 5 days.

Epidemiology of Dengue in patients with febrile syndrome at Saint Camille Hospital, Ouagadougou, Burkina Faso from 2020 to 2

: Dengue is still a public health problem in tropical countries. This disease, which had almost disappeared in some areas of the world, has become re-emergent in certain parts of the world including Africa.The aim of this study is to determine the seroprevalence and evolution of Dengue virus (DENV) infection from 2020 to 2021 at the Hospital Saint Camille de Ouagadougou (HOSCO), Burkina Faso. Methodology: This was a descriptive analytical study of patients seen in general practice with febrile syndrome referred for serological diagnosis of Dengue at the HOSCO laboratory over a period of 2 years (January 1, 2020 ­ December 31, 2021). The "Dengue Duo (AgNS1/IgM/IgG)" kit from SD Bioline was used for the rapid diagnosis through the detection of NS1 antigen and IgM/IgG antibodies in plasma. Data were analysed with SPSS version 20.0 software. Association between demographic data and prevalence of DENV infection was determined by Chisquare test and odds ratio (with 95% confidence interval). P value less than 0.05 was considered statistical significance. Results: A total of 2957 patients aged 0-94 years were referred for serological diagnosis of DENV infection at the HOSCO laboratory over the period 2020-2021, comprising 56.3% females and 43.7% males. The overall prevalence of acute DENV infection (NS1Ag positive) was 5.4% (159/2957), with 2.4% (41/1700) in 2020 and 9.4% (118/1257) in 2021 (OR=4.192, 95% CI=2.915-6.028, p<0.0001). The prevalence of acute DENV infection of 7.0% (91/1292) in the males was significantly higher than 4.1% (68/1665) in the females (OR=1.779, 95% CI=1.288-2.458, p=0.0005), and also significantly higher in age groups 20-29 years (7.6%), 10-19 years (6.9%) and 40-49 years (5.8%) than other age groups (X 2=14.928, p=0.0107). The overall prevalence of DENV IgM and IgG antibodies was 3.2% and 37.3% respectively. The prevalence of DENV IgG antibodies was significantly higher in males (44.0%) than females (32.1%) (OR=1.667, 95%CI=1.434-1.938, p<0.0001) and in age groups 30-39 (43.4%), 40-49 (44.0%) and >50 years (49.3%) than other age groups (X2=121.0, p<0.0001), indicating that past exposure to DENV infection is higher among males and older age groups. The peak of DENV infection was between October and November with 84.3% (134/159) of NS1Ag positivity occurring during this period. Conclusion: The present study reports a high prevalence of acute Dengue virus infection in patients from October to November. To eradicate Dengue which has become a tropical silent epidemic, interventions such as vector control, availability of and accessibility to diagnostic tests, and good therapeutic management are of great importance

Oculocutaneous albinism in southern Africa: Historical background, genetic, clinical and psychosocial issues

Albinism is an inherited condition associated with significant depigmentation of the skin, hair and eyes. It occurs in every population with varying frequency, and narratives of people with albinism have been recorded since 200 BC. In southern Africa albinism is common, about 1 in 4000 people are affected, but it remains a poorly understood condition surrounded by myths and superstition. This article provides a historical background on oculocutaneous albinism (OCA) in southern Africa and presents relevant information from the literature regarding epidemiology, genetics and genetic counselling, health, psychosocial and cultural issues, and medical care. There are several recessively inherited types of OCA and a mutation, responsible for about 80%of South African variants, has been identified in OCA type 2. The physical characteristics associated with albinism, that is, sun-sensitive skin and low vision, can be managed. However, people with OCA in Africa also experience psychosocial issues, such as discrimination, because of the various superstitious beliefs and attitudes held in the community. Management should include medical care for health problems, appropriate adjustment of the schooling context and genetic counseling. In addition, widespread public awareness programs are required to increase the knowledge of the genetic causes of OCA and of the nature of genetic counselling, to address the negative attitudes in the community, to reduce the marginalization and stigmatization of people with albinism and to improve their quality of life.

The first year of the COVID-19 pandemic in the ECOWAS region

Objective: to analyse the pandemic after one year in terms of the evolution of morbidity and mortality and factors that may contribute to this evolution Design: This is a secondary analysis of data gathered to respond to the COVID-19 pandemic. The number of cases, incidence rate, cumulative incidence rate, number of deaths, case fatality rate and their trends were analysed during the first year of the pandemic. Testing and other public health measures were also described according to the information available. Settings: The 15 States members of the Economic Community of West African States (ECOWAS) were considered. Results: As of 31st March 2021, the ECOWAS region reported 429,760 COVID-19 cases and 5,620 deaths. In the first year, 1,110.75 persons were infected per million, while 1.31% of the confirmed patients died. The ECOWAS region represents 30% of the African population. One year after the start of COVID-19 in ECOWAS, this region reported 10% of the cases and 10% of the deaths in the continent. Cumulatively, the region has had two major epidemic waves; however, countries show different patterns. The case fatality rate presented a fast growth in the first months and then decreased to a plateau. Conclusion: We learn that the context of COVID-19 is specific to each country. This analysis shows the importance of better understanding each country's response. During this first year of the pandemic, the problem of variants of concern and the vaccination were not posed.

Première année de la pandémie à COVID-19 en République Démocratique du Congo: Revue de la gestion d'une crise dans un système de santé décentralisé / The first year of COVID-19 in the Democratic Republic of Congo: Crisis management's review in a decentralized health system

La République démocratique du Congo (RDC), frappée par la pandémie de la COVID-19, a mis en place un plan de riposte national au regard du premier objectif de ce plan pendant la première année de crise. Cette étude a passé en revue les différentes composantes de la surveillance et certains piliers du système de santé, éléments critiques pour la compréhension des résultats de la riposte aujourd'hui et future. Un manque d'efficience a été observé dans les chaines internes de communication lié à une faible coordination des intervenants et de leurs interventions ; et des ressources financières insuffisantes. Malgré ces faiblesses la RDC a évité la catastrophe annoncée. Divers facteurs liés à l'environnement, à la structure d'âge de sa population, au niveau de circulation du virus au sein de cette population et d'autres à élucider dans les recherches futures pourraient contribuer à la compréhension de la situation actuelle et influencer la gestion future de gestion des épidémies. Il est évident qu'une meilleure coordination et mobilisation des ressources, ainsi qu'un système de santé résiliant, permettront une meilleure surveillance et une gestion moins stressante des crises sanitaires à venir.

The Democratic Republic of Congo (DRC), hit by the COVID-19 pandemic, has put in place a national response plan. We reviewed the organization of the response in light of the first objective of this plan during the first year of the crisis. This study reviewed the different components of surveillance and some pillars of the health system, which are critical to understanding the results of the response today and in the future. There was a lack of efficiency in internal communication chains due to poor coordination of stakeholders and their interventions; and insufficient financial resources. Despite these weaknesses, the DRC has avoided the announced disaster. Various factors related to the environment, the age structure of its population, the level of circulation of the virus within this population and others to be elucidated in future research could contribute to the understanding of the current situation and influence the future management of epidemics. It is clear that better coordination and resource mobilization, as well as a resilient health system, will allow for better surveillance and less stressful management of future health crises.

Retrospective evaluation of inpatients admitted to a tertiary hospital in Somalia for Pediatric surgery

Objective: The aim is to reflect on the epidemiology of the patient population at a tertiary hospital for pediatric surgery, diagnostic pattern, and mortality in Somalia retrospectively. Methods: In this study, 163 patient who were hospitalized to Pediatric Surgery Clinic of Mogadishu Somalia Turkey Recep Tayyip Erdogan Training and Research Hospital in 2018 were included. Data regarding age, gender, diagnosis, surgical condition, mortality rate and cause of the death were recorded from the patient charts and the institutional digital database Results: Of 163 patients 47 were female (28.8%) and 116 were male (71.2%). The mean age of the patients was 6.4 ± 4.8 years. The main diagnoses were congenital malformation (34.4%), acute abdomen (25.8%), traumatic injury (23.3%), infection (9.8%) and neoplasm (6.1%). Mortality rate was 9.8% and the leading cause of death was sepsis by 87.5%. Perforated appendicitis, intestinal obstruction and intussusception were creating the 68.7% of the diseases that result in death. Conclusions: Our results show that two-thirds of the surgical deaths could be prevented with timely presentation. We think that the health policymakers in Somalia should focus on how to improve the access to surgical care, patient transfer, timely presentation, and training of pediatric surgeons and to overcome the poor surgical outcomes
