[Epidemiolological, Clinical, Etiological, Therapeutic And Evolutive Aspects Of Spontaneous Pneumothoraxes In The Internal Medicine Department Of The University Hospital Center Of Abéche (CHU-A) In Chad].

Introduction: Pneumothorax are frequent reasons for hospitalization in African pneumological settings. The objective of this work was to describe the epidemiological-clinical, etiological, therapeutic and evolutionary aspects of pneumothorax at the Center Hospitalier Universitaire d'Abéché (CHU-A) in Chad.

Materials And Methods: This was a prospective and descriptive study conducted in the internal medicine department, from January 1, 2020 to December 31, 2021 concerning cases of pneumothorax.

Continuing effectiveness of serogroup A meningococcal conjugate vaccine, Chad, 2013.

In 2011, vaccination with a serogroup A meningococcal polysaccharide conjugate vaccine was implemented in 3 of 23 regions in Chad. Cases of meningitis declined dramatically in vaccinated areas, but an epidemic continued in the rest of Chad. In 2012, the remaining Chad population was vaccinated, and the epidemic was halted.

Effect of a serogroup A meningococcal conjugate vaccine (PsA-TT) on serogroup A meningococcal meningitis and carriage in Chad: a community study [corrected].

Background: A serogroup A meningococcal polysaccharide-tetanus toxoid conjugate vaccine (PsA-TT, MenAfriVac) was licensed in India in 2009, and pre-qualified by WHO in 2010, on the basis of its safety and immunogenicity. This vaccine is now being deployed across the African meningitis belt. We studied the effect of PsA-TT on meningococcal meningitis and carriage in Chad during a serogroup A meningococcal meningitis epidemic.
