Neuromyelitis Optica Spectrum Disorders in Black African: Experience of Togo (2015-2020).

 Neuromyelitis optica spectrum disorders (NMOSD) would disproportionately affect blacks within mixed populations. However, they are rarely reported in black African. The objective of this work was to report the experience of Togo, a West African country in terms of NMOSD.

[Guillain-Barré syndrome in hospitals in Togo].

Introduction: In sub-Saharan Africa characterized by limited resources especially in health facilities and a relatively higher frequency of infectious diseases, studies on Guillain-Barré syndrome (GBS) are rare.

Objectives: The objectives of this work are to describe the characteristics of GBS in Togo through a cohort of patients followed in the neurology unit of the Campus University Hospital of Lomé.

Methodology: The study took place from May 2015 to July 2019.

[Brown Sequard syndrome revealing a cervical pott's disease associated with a retropharyngeal abscess].

A 37-year-old patient was admitted for a left progressive left-hand hemiparesis associated with left C4-C5 neuralgia preceded by inflammatory neck pain for 04 months and dysphagia for 02 weeks. Magnetic resonance imaging showed C3-C5 spondylodiscitis lesions with epidural abscess and predominantly left lateralized compression of the spinal cord and retropharyngeal abscess. The patient was operated for incision and drainage of the retropharyngeal abscess through the oral cavity and Koch bacillus was demonstrated from the aspirate by molecular technique GeneXpert.

Case report: an area postrema syndrome revealing a neuromyelitis optica spectrum disorder associated with central nervous system tuberculosis in a young Togolese (black African) woman.

Background: Area postrema syndrome (APS) is considered to be one of the most specific clinical presentations of neuromyelitis optica spectrum disorders (NMOSDs). In sub-Saharan Africa, NMOSDs and even more so those revealed by an APS, are rarely reported. However, studies among mixed populations have shown that NMOSDs disproportionately affect black people with relatively more frequent encephalic involvement.

Rasmussen's Epileptogenic Encephalitis in a Tropical Country.
