BackgroundAlthough sickle cell disease (SCD) children are highly susceptible to bacterial infections (BIs), there is a dreadful lack of data related to the burden and spectrum of BIs in sub-Saharan Africa (SSA), the highest affected region with SCD. This study aimed to determine the burden and spectrum of BIs among SCD children hospitalized in a pediatric reference hospital in Cameroon, a SSA country.MethodsWe conducted a retrospective analysis of records of children hospitalized from November 2012 to August 2015 in the SCD unit of the Mother and Child Centre of the Chantal Biya Foundation, Cameroon. We enrolled all known SCD children aged 15 years or less, hospitalized for a suspicion of BI and who presented a positive culture of a body specimen.ResultsA total of 987 SCD children were hospitalized during the study period. Cultures were positive for 96 patients (9.7%) among whom 60.4% males. Ages ranged from 6 to 192 months with a median of 53 (Interquartile range (IQR) 21–101) months. For children no more covered by the Expanded Programme on Immunization, only 13 (18.8%) had received the Pneumo 23® and Meningo A&C® antigens, and 12 (17.4%), the Typhim vi® and the Haemophilus influenzae type b antigens; 58 children (84.1%) had received no vaccine. The specimen yielding positive cultures were: blood (70.7%), urine (13.1%), pus (9.1%), synovial fluid (4.1%), cerebrospinal fluid (2.0%), and bone fragment (1.0%). The different types of infection included: urinary tract infections (13.5%), myositis (8.3%), arthritis (6.3%), osteomyelitis (4.2%), and meningitis (2.1%); the site of infection was unidentified in 65.6% of cases. The main bacteria included: Salmonella sp. (28.1%), Staphylococcus sp. (18.8%), Klebsiella pneumoniae (17.7%), Escherichia coli (10.4%), Enterobacter sp. (5.2%), Acinetobacter sp. (4.2%), Streptococcus sp. (4.2%) and Serratia sp. (4.2%).ConclusionThis retrospective analysis revealed 9.7% cases of BIs, mainly caused by Salmonella sp. (28.1%), Staphylococcus sp. (18.8%), Klebsiella pneumoniae (17.7%), and Escherichia coli (10.4%).
Background: At the beginning of March 2020, Cameroon experienced its first cases of infection with the new coronavirus (SARS-COV-2). Very quickly, there was a drop in the rate of hospital attendance. The purpose of this study was to observe the variations in the uptake of pediatric consultations and vaccinations in a pediatric hospital. Methods: A descriptive and retrospective cross-sectional study was carried out using consultation and vaccination statistics from a pediatric hospital in the city of Yaoundé, political capital of Cameroon, from January 2016 to May 2020. Data were entered in Microsoft Excel and exported to R software (Version 3.3.3) for statistical analysis. First, time series raw data (before and after COVID-19) were plotted and the trend estimated by locally weighted scatterplot smoothing (LOWESS) methods. Then a classic seasonal decomposition was performed to distinguish between seasonal trends and irregular components using moving averages. The Webel–Ollech overall seasonality test (WO test) was also run to formally check for seasonality. The results of the study are presented as narrative tables and graphs. Results: Following the partial confinement recommended by the government of Cameroon, the number of pediatric consultations decreased by 52% in April and by 34% in May 2020 compared with rates during the same periods in 2019 ( p = 0.00001). For antenatal visits, the rates dropped by 45% and 34%, respectively, in April and May 2020 compared with 2019. The demand for immunization services also declined. As a result, the demand for BCG vaccines, third-dose tracer vaccines (diphtheria, tetanus, pertussis), polio, and MMR in children as well as tetanus vaccines in childbearing women dropped significantly. Conclusion: The start of the COVID-19 pandemic was accompanied by a significant drop in consultation and vaccination activities. If no action is taken to correct this phenomenon, the ensuing months could be marked by a considerable increase in patients, sometimes suffering from vaccine-preventable diseases. The death rate could increase considerably in the pediatric population.
BackgroundAlthough sub-Saharan Africa (SSA) is particularly affected by sickle cell disease (SCD), there is dearth of research on this topic in the region, specifically targeting the magnitude of SCD-related complications. We therefore conducted this study to determine the burden of acute chest syndrome (ACS) and describe its clinical and therapeutic aspects among SCD children in Cameroon, a SSA country.MethodsThis was a retrospective study carried-out from September 2013 to June 2014 at the SCD unit of the Mother and Child Centre of the Chantal Biya Foundation, a pediatric reference centre in Yaoundé, Cameroon. We enrolled all SCD children with confirmed diagnosis of ACS, and recorded their clinical presentation at admission along with their evolution during hospitalization.ResultsTwenty one cases of ACS were identified during the study period, from 338 hospitalizations of children with SCD. Ages ranged from 11 months to 16 years with a mean (standard deviation) of 5.5 (3.4) years, and a male/female sex ratio of 3.2/1. We noticed relatively low levels of HbF, from 6.4 to 21.9 % with a mean of 14.6 % (6.0 %). The three main symptoms at admission were fever (90.5 %), cough (81 %) and chest pains (28.6 %). Two patients (9.5 %) developed ACS 2 days after admission. The mean values of leukocytes, neutrophils, serum CRP, serum LDH and hemoglobin were respectively 32479.4 (17862.3)/mm3, 23476 (11543.7)/mm3, 228.2 (132.6) mg/l, 3452.3 (2916.3) IU/l and 6.5 (1.2) g/dl. The main localizations of radiological alveolar consolidations were the lower lobes (90.5 %). Treatment associated broad-spectrum antibiotics (100 %), hydration (100 %), analgesics (43.2 %), whole blood transfusion (66.7 %), and oxygen supplementation (33.3 %). Blood transfusion significantly improved hemoglobin level (p = 0.039). The duration of hospitalization, the mean of which was 6.8 (3.1) days, was influenced by none of the tested variables (all p values > 0.05).ConclusionACS is frequent among SCD children in our milieu. Its etiologies seem to be multifactorial. Patients’ parents should be educated to recognize early signs and symptoms of the disease, and consult rapidly. Additionally, clinicians must be trained to diagnose ACS, and manage it promptly and efficiently to avoid its related catastrophic consequences.
Background: The COVID-19 pandemic reached Cameroon in March, 2020. The aim of this study was to unveil the consequences of this pandemic on hospitalizations and on mortality in a pediatric hospital. Methods: A descriptive and retrospective cross-sectional study was carried out using hospitalization and death statistics collected from a pediatric hospital. We compared the data before and after the pandemic and made predictions for the next 12 months. Results: A drastic drop in hospitalizations was noted coinciding with the partial lockdown in Cameroon. Paradoxically, at the same time, the number of deaths per month doubled though the causes remained the same as in the past. Conclusion: The COVID-19 pandemic was marked by drop in hospitalizations and paradoxically, an increase in child mortality. These deaths were probably due not to SARS-Cov-2 infection, but rather due to the usual illnesses whose management was delayed, a probable consequence of the confinement.
Background:Endomyocardial fibrosis (EMF) is a neglected heart condition of the inter-tropical regions. Numerous hypotheses suggest a relationship between its geographical distribution in the affected regions and other etio-pathogenic factors such as dietary habits, infectious causes, and geochemical causes. Knowledge of its epidemiology in Cameroon remains limited, which is why we decided to describe the profile of a paediatric series of EMF in Yaoundé.Patients and Methods:A retrospective study was carried out on EMF in 54 patients diagnosed from 1 January 2006-31 December 2014 in a Paediatric Centre of Yaoundé. Diagnosis was mainly echocardiographic. We compiled data on the geographic origins of the patients, their dietary habits and the socioeconomic profile of their families.Results:The patients’ ages ranged from 2 to 17 years, most of whom (83.3%) were between 5 and 15 years. For geographical distribution, all came from three tropical forest zones where they have lived since their childhood. These were Center (32/54), South (12/54), and East (10/54). All families had a moderate income, consumed tubers at least twice a week especially cassava (43/54) and had low sources of proteins.Conclusion:Apart from geographical similarities all patients of our series shared the same dietary habits. Our study was conducted in a hospital setting; therefore a screening of the disease in the whole national territory would enable a more reliable mapping.
Introduction Les maladies rares ont pour certaines des manifestations orales. Celles-ci sont souvent sous-étudiées; ce qui contribue à limiter l'offre de soins bucco-dentaires pour cette catégorie de patients. Le but est de déterminer les aspects épidémiologiques et cliniques des manifestations bucco-dentaires dans les maladies rares dans notre milieu. Méthodes Nous avons effectué une étude transversale et descriptive sur une durée de 7 mois, dans deux hôpitaux de référence de Yaoundé: les informations ont été recueillies des dossiers médicaux, de l'interrogatoire des parents ou tuteurs et de l'examen bucco-dentaire des patients. Le seuil de significativité considéré pour p < 0,05. Résultats Les manifestations orales sur maladies rares sont variables et fonction du groupe d'affections, de la denture, et ont souvent un retentissement fonctionnel. Elles étaient présentes dans 97,2% de nos patients. En denture temporaire (59,4%), c'était plus des anomalies de forme et de position dentaire (conicité dentaire 7 cas/22, soit 32%), et en denture permanente des lésions carieuses (7 cas/10 soit 70%) et des anomalies de structure dentaire (4 cas/10 d'usure dentaire). Un lien significatif existait entre le type de denture, l'anomalie de structure (p=0,001) et de nombre (p=0,018). Les difficultés à la mastication (p=0,023) et à la succion (p=0,033) étaient liées aux groupes de maladies rares. Conclusion Les lésions orales dans les maladies rares bien que présentes dans notre milieu, sont souvent négligées. Les soins bucco-dentaires devraient être intégrés dans le paquet minimum des activités des formations sanitaires et rendus gratuits ou financièrement accessibles à ces patients handicapés ou présentant des besoins spécifiques.
