Abstract
Assessing the prevalence of toxoplasmosis in pregnant women and the associated risk factors is the first step in defining policy for the prevention of congenital toxoplasmosis in a given population. An epidemiological study was conducted during prenatal consultations at the CHU-MEL of Cotonou (Benin) between September 2018 and April 2021 and recruited 549 pregnant women to determine the seroprevalence and potential factors associated with Toxoplasma gondii infection. Toxoplasma gondii IgG/IgM antibodies were detected using an enzyme-linked fluorescence assay (ELFA) technique, an IgG avidity test and an IgG/IgM comparative Western blot to diagnose the maternal toxoplasmosis serological status, the possibility of an infection acquired during pregnancy and congenital infection, respectively. Concomitantly, the participants answered a questionnaire investigating potential risk factors. Toxoplasmosis seroprevalence was estimated at 44.4% (95% CI 40.3-48.6) and the factors significantly associated with T. gondii seropositivity were: age over 30 years, multigravid women and contact with cats. The possibility of an infection acquired during the periconceptional period or the first trimester of pregnancy concerned six women [1.1% (95% CI 0.5-2.0)]. However, due to the low rate of serological controls in seronegative women, a significant proportion of women first tested during the 3rd trimester of pregnancy, and an insufficient sample size, the incidence of primary infection during pregnancy could not be determined. No cases of congenital transmission occurred in the newborns from the suspected cases of primary infection.

Abstract
BACKGROUND Cerebral malaria (CM) is a neuropathology which remains one of the deadliest forms of malaria among African children. The kinetics of the pathophysiological mechanisms leading to neuroinflammation and the death or survival of patients during CM are still poorly understood. The increasing production of cytokines, chemokines and other actors of the inflammatory and oxidative response by various local actors in response to neuroinflammation plays a major role during CM, participating in both the amplification of the neuroinflammation phenomenon and its resolution. In this study, we aimed to identify risk factors for CM death among specific variables of inflammatory and oxidative responses to improve our understanding of CM pathogenesis. METHODS Children presenting with CM (n = 70) due to P. falciparum infection were included in southern Benin and divided according to the clinical outcome into 50 children who survived and 20 who died. Clinical examination was complemented by fundoscopic examination and extensive blood biochemical analysis associated with molecular diagnosis by multiplex PCR targeting 14 pathogens in the patients' cerebrospinal fluid to rule out coinfections. Luminex technology and enzyme immunoassay kits were used to measure 17 plasma and 7 urinary biomarker levels, respectively. Data were analysed by univariate analysis using the nonparametric Mann‒Whitney U test and Pearson's Chi2 test. Adjusted and multivariate analyses were conducted separately for plasma and urinary biomarkers to identify CM mortality risk factors. RESULTS Univariate analysis revealed higher plasma levels of tumour necrosis factor (TNF), interleukin-1beta (IL-1β), IL-10, IL-8, C-X-C motif chemokine ligand 9 (CXCL9), granzyme B, and angiopoietin-2 and lower urinary levels of prostanglandine E2 metabolite (PGEM) in children who died compared to those who survived CM (Mann-Whitney U-test, P-values between 0.03 and < 0.0001). The multivariate logistic analysis highlighted elevated plasma levels of IL-8 as the main risk factor for death during CM (adjusted odd ratio = 14.2, P-value = 0.002). Values obtained during follow-up at D3 and D30 revealed immune factors associated with disease resolution, including plasma CXCL5, C-C motif chemokine ligand 17 (CCL17), CCL22, and urinary 15-F2t-isoprostane. CONCLUSIONS The main risk factor of death during CM was thus elevated plasma levels of IL-8 at inclusion. Follow-up of patients until D30 revealed marker profiles of disease aggravation and resolution for markers implicated in neutrophil activation, endothelium activation and damage, inflammatory and oxidative response. These results provide important insight into our understanding of CM pathogenesis and clinical outcome and may have important therapeutic implications.

Abstract
Studies suggest that elevated postnatal blood lead levels (BLLs) are negatively associated with child growth. This study aimed to investigate the associations of childhood BLLs at age one year and growth outcomes at age six years (n = 661) in a cohort of children in Allada, Benin. The growth outcomes studied are weight-for-age Z-score (WAZ), height-for-age Z-score (HAZ), BMI-for-age Z-score (BMIZ), weight-for-height Z-score (WHZ), head circumference (HC), growth velocities, underweight, stunting, and wasting. Multivariable regression models examined the associations between BLLs and growth outcomes, with adjustment for potential confounders. The geometric mean BLLs was 59.3 μg/L and 82% of children had BLLs >35 μg/L at the age of 12.8 months. After adjusting for confounding factors, no overall association was found between BLL quartiles and HAZ, WAZ, BMIZ, WHZ, growth velocities, wasting, and underweight. However, boys in the highest quartile had a 1.02 cm lower HC (95% CI: [−1.81, −0.24]) as compared to the lowest quartile. Furthermore, an increased odds of being stunted was observed in children in the highest quartile of exposure compared to the first (OR: 2.43; 95% CI: [1.11−5.33]) which remained statistically significant only among girls in sex-specific strata. Blood lead was found to be associated with an increased risk of childhood stunting and a lower head circumference in a resource-limited setting.

Abstract
Background While malaria morbidity and mortality have declined since 2000, viral central nervous system infections appear to be an important, underestimated cause of coma in malaria-endemic Eastern Africa. We aimed to describe the etiology of non-traumatic comas in young children in Benin, as well as their management and early outcomes, and to identify factors associated with death. Methods From March to November 2018, we enrolled all HIV-negative children aged between 2 and 6 years, with a Blantyre Coma Score ≤ 2, in this prospective observational study. Children were screened for malaria severity signs and assessed using a systematic diagnostic protocol, including blood cultures, malaria diagnostics, and cerebrospinal fluid analysis using multiplex PCR. To determine factors associated with death, univariate and multivariate analyses were performed. Results From 3244 admissions, 84 children were included: malaria was diagnosed in 78, eight of whom had a viral or bacterial co-infection. Six children had a non-malarial infection or no identified cause. The mortality rate was 29.8% (25/84), with 20 children dying in the first 24 h. Co-infected children appeared to have a poorer prognosis. Of the 76 children who consulted a healthcare professional before admission, only 5 were prescribed adequate antimalarial oral therapy. Predictors of early death were jaundice or increased bilirubin [odd ratio (OR)= 8.6; 95% confidential interval (CI): 2.03–36.1] and lactate > 5 mmol/L (OR = 5.1; 95% CI: 1.49–17.30). Antibiotic use before admission (OR = 0.1; 95% CI: 0.02–0.85) and vaccination against yellow fever (OR = 0.2, 95% CI: 0.05–0.79) protected against mortality. Conclusions Infections were found in all children who died, and cerebral malaria was by far the most common cause of non-traumatic coma. Missed opportunities to receive early effective antimalarial treatment were common. Other central nervous system infections must be considered in their management. Some factors that proved to be protective against early death were unexpected. Supplementary Information The online version contains supplementary material available at 10.1186/s40249-022-00956-2.

Abstract
INTRODUCTION In 2016, an estimated 216 million cases and 445 000 deaths of malaria occurred worldwide, in 91 countries. In Benin, malaria causes 26.8% of consultation and hospitalisation motif in the general population and 20.9% in children under 5 years old.The goal of the NeuroCM project is to identify the causative factors of neuroinflammation in the context of cerebral malaria. There are currently very few systematic data from West Africa on the aetiologies and management of non-malarial non-traumatic coma in small children, and NeuroCM will help to fill this gap. We postulate that an accurate understanding of molecular and cellular mechanisms involved in neuroinflammation may help to define efficient strategies to prevent and manage cerebral malaria. METHODS AND ANALYSIS This is a prospective, case-control study comparing cerebral malaria to uncomplicated malaria and non-malarial non-traumatic coma. This study takes place in Benin, precisely in Cotonou for children with coma and in Sô-Ava district for children with uncomplicated malaria. We aim to include 300 children aged between 24 and 71 months and divided in three different clinical groups during 12 months (from December 2017 to November 2018) with a 21 to 28 days follow-up for coma. Study data, including clinical, biological and research results will be collected and managed using CSOnline-Ennov Clinical. ETHICS AND DISSEMINATION Ethics approval for the NeuroCM study has been obtained from Comité National d'Ethique pour la Recherche en santé of Benin (n°67/MS/DC/SGM/DRFMT/CNERS/SA; 10/17/2017). NeuroCM study has also been approved by Comité consultatif de déontologie et d'éthique of Institut de Recherche pour le Développement (IRD; 10/24/2017). The study results will be disseminated through the direct consultations with the WHO's Multilateral Initiative on Malaria (TDR-MIM) and Roll Back Malaria programme, through scientific meetings and peer-reviewed publications in scientific or medical journals, and through guidelines and booklets.

Abstract
BACKGROUND In many developing countries, faulty complementary feeding practises and frequently contaminated foods are contributing factors to child malnutrition. The aims of this study were to evaluate the nutrition status of, and clarify the maternal safe food preparation behaviors associated with malnutrition in, children aged <5 years in Cotonou, Benin. METHODS This study targeted 300 mother-child pairs visiting the University Hospital of Mother and Child Cotonou Lagoon. Mothers were interviewed using a structured questionnaire. Child height/length and weight measurements were determined and Z-scores were calculated using the 2006 World Health Organization Child Growth Standards. Children with Z-score < -2 were considered to have stunting or be underweight. On logistic regression analysis, significant variables on bivariate analysis, the associations of which were clarified in previous studies, were established as independent variables. Approximately 80% of the children who participated in this study were aged < 1 year. Being underweight was analyzed as a dependent variable. RESULTS Regarding nutrition status, 11.0% of the children had stunting and 14.7% were underweight. On logistic regression analysis, underweight was correlated significantly with birthweight. As a remarkable point, food refrigeration was statistically significant. Food refrigeration can possibly be regarded as a maternal safe food preparation behavior. CONCLUSIONS Maternal safe food preparation behaviors can prevent child malnutrition, even after considering biological and socioeconomic factors.

Abstract
AIMS In this study, the objective was to determine the proportion of severe anemia and hypoglycemia in severe malaria in children and to identify factors influencing death. PATIENTS AND METHODS This is a descriptive and analytic cross-sectional study with prospectively collected data from January to December 2009. It included children from one month to fourteen years of age hospitalized in the Parakou Regional Hospital Center in Benin for severe malaria according to the World Health Organization (WHO) criteria. RESULTS Among the 1838 cases, 968 cases (52.6%) had either severe anemia or hypoglycemia or both. Among these, 89% were under 5 years. Biologically, the mean parasite density was 40 062/mm3 and the mean hemoglobin rate was 4.94 g/dl. The average blood glucose was 0.45 g/l. The mortality rate was 8.2%. Death occurrence rate was significantly higher in under five children's group hospitalized for severe anemia and/or hypoglycemia compared to those of the same age group with others forms of severe malaria (p=0,000081). CONCLUSION This work suggests the importance of hypoglycemia and anemia among factors associated with death in children's severe malaria.

Abstract
Growth disorders are frequent in human and are represented mainly by malformation recognizable pre and postnatally. These malformations contribute to infant morbidity and mortality. They could occur in any organ and system. While seated in limbs, they could lead to severe functional difficulties as it was seen in this observation with forearm and legs agenesis. No case was reported before in Benin.

Abstract
BACKGROUND In tropical countries, iatrogenic retractile quadriceps fibrosis (IRQF), the cause of walking handicap in children, is often the result of intraquadricipital injection of quinine salts. The aim of this review was to analyse the epidemiological, clinical, therapeutic aspects and outcome of IRQF in children admitted in three hospitals in Benin Republic. PATIENTS AND METHODS It was a 10-year retrospective, descriptive and analytic survey of IRQF, involving 81 children aged from 8 months to 15 years. Iterative mobilization of the knee (IMK) or modified distal quadriceps plasty by Thompson-Payr's technique (MDQTPT), with a POP on the knee in flexion position, was performed with additional functional rehabilitation. The results were evaluated on knee flexion gain and walking quality. Data were processed using Epi Info 3.2 software. RESULTS Patients' average age was 7.60 years. Children of 6-10 years were most affected; sex ratio was 1.02. Lesions were unilateral (71.6%) and bilateral (28.4%). The knees' stiffness was in flexion (10.57%), rectitude (64.42%) and recurvatum (25%). The amyotrophy of the thigh was found in 79.42 %. The IMK was successful in eight cases (7.69 %) and the MDQTPT was done in 98 cases (94.23%) associated with femoral osteotomy in 13 cases (12.50%). In post-surgical period, skin necrosis and fractures occurred respectively in 15.31% and 5.10%. Results were good in 92.31% of cases. CONCLUSIONS IRQF in children do exist in our settings. The treatment that is based on MDQTPT associated to rehabilitation leads to acceptable outcome.

Abstract
OBJECTIVE To describe the profile of HIV-infected children. METHODS This was a cross-sectional, descriptive and analytic study involving 317 infected children, monitored from January 1st, 2002 to July 31st, 2010 at CNHU of Cotonou. RESULTS The average age was 89.1 months with a sex ratio of 0.91. Orphans of at least one parent represented 31.3% of cases. Vertical transmission was predominant (86.1%). Only 9.5% of patients benefited from PMTCT. They were all infected with HIV 1. According to the WHO classification, 52% were at stage 3 or 4 and 56% had advanced to severe immunodeficiency. 61% had suffered from opportunistic infections, and 53% had benefited from antiretroviral therapy. Following the study, 54% of participants had continued follow-up visits, 23% lost contact with the CNHU, 18% died and 5% were referred to another site. Factors associated with outcome were antiretroviral therapy (p < 0.0001), clinical (p < 0.0001) and immunological stage (p = 0.0042) on admission. CONCLUSION Our findings suggest strengthening the PMTCT program, screening and early management of an HIV infection.

Abstract
Blepharophimosis-ptosis-epicanthus inversus syndrome (BPES) is a rare autosomal dominant disorder whose main features are the abnormal shape, position and alignment of the eyelids. Type I refers to BPES with female infertility from premature ovarian failure while type II is limited to the ocular features. A causative gene, FOXL2, has been localized to 3q23. We report a black female who carried a de novo chromosomal translocation and 3.13 Mb deletion at 3q23, 1.2 Mb 5' to FOXL2. This suggests the presence of distant cis regulatory elements at the extended FOXL2 locus. In spite of 21 protein coding genes in the 3.13 Mb deleted segment, the patient had no other malformation and a strictly normal psychomotor development at age 2.5 years. Our observation confirms panethnicity of BPES and adds to the knowledge of the complex cis regulation of human FOXL2 gene expression.

Abstract
The femoral hypoplasia-unusual facies syndrome is a very rare association of femora and facial abnormalities. The most common features include hypoplasia of the femora and a characteristic facies with a short nose, long philtrum, thin upper lip and micrognathia. Maternal diabetes mellitus has been mainly identified as the causal agent. We reported the first case in a black African and discuss prenatal diagnosis and aetiology.

Abstract
AIM To study the epidemiologic, clinic, biologic and therapeutics aspects of pleural effusion at National university healty center (CNHU) of Cotonou. METHOD From January 2004 to December 2008, we have conduct a retrospective study in the pediatric service of Cotonou’s CNHU. 15 children less than 5 years old were included in the study. A chest X ray radiography have been done for all the children at the hospitalization. Epi info and chi square test were used for the statistical study. RESULT Pleural effusion’s incidence is growing in the service and in this statement children old less than 5 years are more concerned. Fever, chest and abdominal complaints were the most clinical sign.The diagnosis of pleural effusion was established in 56.3% and Staphylococcus aureus was found. Antibiotic, pleural puncture and blood transfusion were used as therapeutics method. Mortality rate was 5.6%. In conclusion, pleural effusion management in Cotonou CHNU is suffering by the etiologic diagnosis of the disease.

Abstract
Familial Tumoral Calcinosis (FTC) is a rare autosomal recessive disorder of the phosphocalcic metabolism caused by mutations in the FGF23 or GALNT3 genes. We have identified a Beninese family in which two brothers present FTC caused by a homozygous A>T transversion at the acceptor splice site in intron 1 of GALNT3 gene. We report on the clinical, biochemical, histopathological and molecular spectrum of the disorder in this family. The particularly severe phenotype, the amelogenesis imperfecta, and the carbapatite deposit observed in these patients, seem to be characteristic of our observations.

Abstract
Ring chromosome 4 associates concomitant loss of the telomeric 4p and 4q regions and leads to variable clinical manifestations depending on the size of the deleted chromosomal material. We report on a patient with ring chromosome 4, showing the Wolf-Hirshhorn Syndrome (WHS) phenotype and minor symptoms of distal 4q deletion syndrome; the severity of the signs of WHS masks the symptomatology of the 4q deletion syndrome. The absence of seizures despite the absence of the specific 4p16.3 region with haploinsufficiency of the LETM1 gene is striking. The double telomeric deletion due to the ring chromosome formation confirmed by FISH has been rarely described in WHS.
