Abstract
In December 2015, as part of the First African Dialysis Conference organized in Dakar, Senegal, 5 physicians from West African countries who have participated in the Saving Young Lives Program reviewed their experiences establishing peritoneal dialysis (PD) programs to treat patients with acute kidney injury (AKI). Thus far, nearly 200 patients have received PD treatment in these countries. The interaction and discussion amongst the participants at the meeting was meaningful and informative. The presentations highlighted the creativity, conviction, and determination of the physicians in overcoming the various barriers and challenges they encountered to establish PD/AKI programs. Hopefully, these successes and the increased awareness of the importance of early diagnosis and treatment of AKI will inspire much needed support from government, hospital, and international organizations.

Abstract
Objectives: The socioeconomic profile of households and families of children attending hospital for hydrocephalus were documented and analysed. Main costs related to diagnosis and care were reviewed. The emotional fallout and social well-being of families were also analysed. Methods: This retrospective cross-sectional study (January 2006 to January 2015) was based on costs borne by households and families for neurosurgical care of children with hydrocephalus. Results: Sixty children (1 day to 12 years old) had been hospitalized for hydrocephalus in Cotonou-Benin. In 19 cases, the families were single-parent families. In 44 cases, the parents were self-employed workers or private company employees. Public servants, eligible for national health system assistance, accounted for a mere 16 cases. Twenty six children did not receive any financial support, whereas the total average care-related out-of-pocket expenditure for families during the hospital stay was approximately €1,777 (1,117,500 FCFA), i.e. almost 14 times the average monthly income reported by the parents (82,600 FCFA – approximately €120). After hospitalization, 31 mothers had lost their jobs and 21 couples experienced marital issues and their plans to have children. Twelve recent separations were recorded, as well as one indirect maternal death related to depression. Conclusion: In Benin Republic, surgical care for paediatric hydrocephalus represents catastrophic out-of-pocket expenditures for households and families and other living expenses. Families experience significant emotional fallout with effects on couple relationships and survival.

Abstract
BACKGROUND Plasmodium falciparum erythrocyte membrane protein-1 (PfEMP-1) is a highly polymorphic adherence receptor expressed on the surface of infected erythrocytes. Based on sequence homology PfEMP-1 variants have been grouped into three major groups A-C, the highly conserved VAR2CSA variants, and semi-conserved types defined by tandem runs of specific domains ("domain cassettes" (DC)). The PfEMP-1 type expressed determines the adherence phenotype, and is associated with clinical outcome of infection. METHODS Parasite isolates from Beninese children or women presenting with, respectively, CM or PAM were collected along with samples from patients with uncomplicated malaria (UM). We assessed the transcript level of var genes by RT-qPCR and the expression of PfEMP-1 proteins by LC-MS/MS. RESULTS Var genes encoding DC8 and Group A PfEMP-1 were transcribed more often and at higher levels in cerebral malaria vs. uncomplicated malaria patients. LC-MS/MS identified peptides from group A, DC8 PfEMP-1 more frequently in cerebral malaria than in uncomplicated malaria and pregnancy-associated malaria samples. CONCLUSION This is the first study to show association between PfEMP-1 subtype and disease outcome by direct analysis of parasites proteome. The results corroborate that group A and specifically the PfEMP-1 types DC8 are universally associated with cerebral malaria. This is a crucial observation for promoting studies on malaria pathogenesis.

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
Background Variant surface antigens (VSA) expressed on the surface of Plasmodium falciparum-infected red blood cells constitute a key for parasite sequestration and immune evasion. In distinct malaria pathologies, such as placental malaria, specific antibody response against VSA provides protection. This study investigated the antibody response specifically directed against VSA expressed by parasites isolated from individuals presenting a given type of clinical presentation. Methods Plasma and isolates were obtained from four groups of Beninese subjects: healthy adults, patients presenting uncomplicated malaria (UM), cerebral malaria (CM), or pregnancy-associated malaria (PAM). The reactivity of plasma samples from each clinical group was measured by flow cytometry against parasites isolated from individuals from each clinical group. Results Antibody responses against VSAUM were predominant in CM, UM and HA plasmas. When analysed according to age in all plasma groups, anti-VSACM and -VSAUM antibody levels were similar until six years of age. In older groups (6-18 and >19 years of age), VSAUM antibody levels were higher than VSACM antibody levels (P = .01, P = .0008, respectively). Mean MFI values, measured in all plasmas groups except the PAM plasmas, remained low for anti-VSAPAM antibodies and did not vary with age. One month after infection the level of anti-VSA antibodies able to recognize heterologous VSACM variants was increased in CM patients. In UM patients, antibody levels directed against heterologous VSAUM were similar, both during the infection and one month later. Conclusions In conclusion, this study suggests the existence of serologically distinct VSACM and VSAUM. CM isolates were shown to share common epitopes. Specific antibody response to VSAUM was predominant, suggesting a relative low diversity of VSAUM in the study area.

Abstract
UNLABELLED BACKGROIUND: Tuberculosis (TB) is a public health problem. Knowing its patterns could help address it more efficiently. OBJECTIVE To determine the hospital incidence, presentation, management, and outcome of TB in our setting. METHODS We conducted a chart review of children with TB during a five-year period at the University Hospital CNHU-HKM, Cotonou, Benin. RESULTS Hospital prevalence of TB among hospitalised children was 0.2%. The mean age was six years, with a male:female ratio of 1.4:1. The common clinical features were: cough (78.1%), long standing fever (81.2%), growth retardation (65.6%), pulmonary consolidation (53.1%) and hepatosplenomegaly (34.4%). The skin tuberculin test was positive in only 40.6% of cases. Co-infection with HIV was present in 51.8% of cases. Mycobacterium tuberculosis could be identified in only 21.8% of cases. Twenty-six (81.2%) pulmonary tuberculosis (PTB) cases were diagnosed, eight (25%) of which were associated with extra pulmonary TB. Six (18.7%) presumed isolated extra PTB were also diagnosed. Eight-month treatment regimen was used in most patients, with mortality rate of 9.3%. CONCLUSION Although TB hospital prevalence seems low in our setting, management needs to be improved according to guidelines.
