[Clinical neurological signs of human African trypanosomiasis at the meningoencephalitis stage (apropos of 23 cases)].

Twenty-three patients with trypanosomiasis in the meningo-encephalitic period have been examined neurologically. Main neurological symptoms are evocative of the affection and consist in frontal syndrome, often shown by a cheiro-chin reflex, the most frequent objective neurological sign, extrapyramidal injury, neuro-endocrine dysfunction, vestibular, cerebellar, pyramidal and meningitis syndromes. Cerebro-spinal alterations are not steadfast.

[Trypanosomiasis at the Neuropsychopathologic Center of Kinshasa University].

The recent building of a Neuropsychopathologic Center at the Kinshasa University now allows to carry out clinical, electroencephalographic studies on human african trypanosomiasis and soon neuropsychopathologic ones. These studies are reported here.

[Postpregnancy psychoses in Kinshasa. Various clinical and hormonal aspects].

Some clinical and hormonal points of view about forty post-partum psychotics are the object of this study. We have pointed the relatively young age of the patients and the heredo-familial factors importance. From a clinical point of view, we must notice the prevalence of sharp delirious blasts and of depression with regard to western studies.

[Empyema and subdural effusion after meningitis. 2 cases of unusual location].

A 12-year old child and a 2-month old infant developed, in the wane of a purulent meningitis, the former, an infratentorial subdural empyema, the latter, a large, encapsulated, haemoorhagic, aseptic subdural effusion, in the right parieto-temporo-occipital region. In both cases, signs of intracranial hypertension dominated the clinical picture. Neuroradiological investigations permitted diagnosis and localisation of the expansive processes, whose subdural position was recognized at operation and confirmed by histopathological examination.
