Objectives: Tuberculosis (TB) diagnosis in children remains challenging due to the paucibacillary nature of specimens and the difficulty in obtaining suitable samples. The use of alternative samples like nasopharyngeal aspirate (NPA) and stools, alongside Xpert MTB/RIF testing, offers promising improvements. This study aimed to assess the diagnostic performance of the Xpert MTB/RIF test on NPA and stool samples for detecting intrathoracic TB in children from Madagascar, Cameroon, and Ivory Coast.

Article Synopsis
- Childhood community-acquired pneumonia is a major health issue in low-income countries, with common pathogens including Staphylococcus aureus, Streptococcus pneumoniae, and Mycoplasma pneumoniae; the latter is linked to asthma patients particularly in Madagascar where asthma prevalence is high.
- A study involving 351 children aged 2 to 16 years was conducted to assess the prevalence of M. pneumoniae infection, categorizing them into control, asthma, and pneumonia groups, and analyzing their IgG and IgM antibody levels.
- The findings showed an overall M. pneumoniae infection prevalence of 18.2%, and surprisingly, the infection was more common in the control group than in the asthma
Background: Diarrheal disease remains a leading cause of death in children in low-income countries. We investigated the etiology, risk factors and effects on nutritional status of severe diarrhea in children from two districts in Madagascar.
Methods: We performed a matched case-control study in 2011 to 2014, on children under the age of five years from Moramanga and Antananarivo.
Aim: The aim of our study was to assess the prevalence, risk factors for acquisition and the clinical characteristics of H. pylori infection in Malagasy children.
Methods: A 2 year prospective study was conducted among 434 children from a rural (group A) and an urban area (group B).
