[Gayet-Wernicke's encephalopathy. A study of 13 cases observed in a refugee population hospitalized at the Conakry Teaching Hospital]. / Encéphalopathie de Gayet-Wernicke. Etude de 13 observations dans une population de patients réfugiés hospitalisés pour affections neurologiques au CHU de Conakry.

The authors report 13 cases of Gayet-Wernicke's encephalopathy observed in 13 patients of a refugee population. 11 presented the classical triad: oculomotor signs, cerebral ataxia and state of confusion and in 2 patients, only 2 symptoms were noted. The etiological factors: chronic alcoholism, malnutrition, uncontrollable vomiting, HIV and tuberculosis were identified. The outcome was evaluated on the basis of the disappearance of symptoms after treatment with 500 mg of thiamine in 7 patients, 1 death and 5 patients progressed toward Korsakoff amnesic syndrome.

[Clinical and tomographic aspects of 29 cases of phakomatosis in Guinea]. / Aspects clinique et scannographique de 29 observations de phacomatoses en Guinée.

The purpose of this report is to describe 29 cases of phakomatosis including 18 cases of tuberous sclerosis (Bourneville) and 11 cases of neurofibromatosis (von Recklinghausen) observed over a 10-year period at the Neurology Department of the University Hospital Centre in Conakry, Guinea. Findings during this period were consistent with those classically reported in the literature: high frequency of advanced skin lesions coalescing into massive tumours, occurrence of seizures of all types and development of a wide variety of complications as a result of late diagnosis. Our experience underscores the need for follow-up and surveillance of these patients by somatic studies based on neurological, ophthalmologic and tomographic data depending on clinical findings.

[Cardiovascular manifestations in systemic lupus erythematosus in Dakar: Descriptive study about 50 cases]. / Les manifestations cardio-vasculaires au cours du lupus érythémateux systémique à Dakar : étude descriptive à propos de 50 cas.

Systemic lupus erythematosus is a non-specific inflammatory disorder of an organ of unknown cause and autoimmune origin. Visceral injuries, including those cardiovascular, determine the prognosis of this disease primarily affecting women. The objectives of this study were to determine the frequency and describe the cardiovascular manifestations in systemic lupus erythematosus in a lupus population of the Dakar region. This is a multicenter prospective study descriptive and analytical conducted in the region of Dakar (Senegal) from 14 February 2011 to 2 July 2012. Patients were either hospitalized or monitored as outpatients. Included were all patients with lupus and meeting at least four criteria of the American College of Rheumatology of lupus disease classification 1997. All patients underwent physical examination, an electrocardiogram and an echocardiogram looking for cardiovascular damage. The collected data were entered into the Epi Info version 3.5.1 and processed with SPSS 16.0 software. Quantitative variables are described in the median and the qualitative workforce, percentage and frequency. We have included 50 patients. The average age of the population was 36.18 years. A female predominance is noted with a sex ratio man/woman of 0.09. Cardiovascular functional symptoms were dominated by dyspnea stage II to IV NYHA (26%) and palpitations (22%). The physical signs we have found were mainly tachycardia (40%), spontaneous turgor of the jugular veins (29%), a muffling of the heart sounds (29%) and a infandibulopulmonairy shock (18%). The frequency of cardiovascular events was 46%. Electrical cardiac events were dominated by sinus tachycardia (40%) of repolarization disorders (16.3%) type of ischemia, injury, ischemia injury, necrosis and hypertrophy with 18% atrial and left ventricular hypertrophy each. Furthermore, one case of BAV first degree at 280 ms was recorded. We found 19 cases of pericarditis including 2 tamponade, 3 cases of dilated cardiomyopathy hyperkinesias with impaired ejection fraction less than 35% and 8 patients with mild PAH important. In systemic lupus erythematosus, cardiovascular events are worrying and may remain asymptomatic for awhile. Their research must be systematic in order to treat early.

[Late occurrence of first epileptic seizures: a 42-case series]. / Premières crises epileptiques tardives. Etude de 42 cas.

Late occurrence of epilepsy is common in tropical areas. This report describes a series of 42 cases of late epilepsy collected over a three-year period. Findings were consistent with the literature: highest incidence in young age groups, predominance of partial symptomatic epilepsy, and wide spectrum of etiologies. The most frequent etiology was tumoral disease followed by vascular and infectious disease. Brain CT scan and electro-encephalography were highly useful for identification of clinical and etiological entities.

[Atypical neurosyphilis: 28 cases observed at the University Hospital Center of Conakry]. / Neurosyphilis atypique etude de 28 cas observes au CHU de Conakry.

This study describes a series of 28 cases of neurosyphylis presenting atypical oligosymptomatic syndromes involving epileptic attack, chronic headache, peripheral facial paralysis, deafness, isolated optic atrophy, and cerebral ataxia. Diagnosis was based on positive results (VDRL-TPHA) of serological reactions in blood samples and analysis of cerebrospinal fluid showing pleocytosis (mean lymphocyte level, 69%) and elevated protein levels. Epilepsy and chronic headache were the most common clinical manifestations. Brain scan demonstrated low-grade ventricular dilatation associated with nonspecific cerebral atrophy in 8 cases and isolated cerebral atrophy in three. In the remaining 17 cases brain scans were normal.

[Wilson's disease: study of 6 neurologic forms observed at the University Hospital in Conakry]. / Maladie de Wilson: étude de 6 formes neurologiques observées au CHU de Conakry.

This report describes 6 cases of Wilson's disease observed at the University Hospital Center in Conakry, Guinea. Presenting symptoms involved extrapyramidal syndrome in 4 cases, psychomotor epilepsy in 1, and confusional syndrome in 1 case. Diagnosis was based on neuropsychic manifestations, Kayser-Fleicher corneal ring, liver failure, and impaired copper metabolism. Brain CT-scan depicted normal features in 3 cases, symmetric hypodensity of the lenticular nucleus in one, discrete ventricular dilatation of in one a and cortico-subcoetical atrophy in one.

Aspects clinique et scannographique de 29 observations de phacomatoses en Guinee

Les auteurs rapportent 29 observations de phacomatoses dont 18 cas de sclerose tubereuse de Bourneville et 11 cas de neurofibromatose de Recklinghausen; observees dans le service de neuro l ogie du centre hospitalo-universitaire de Conakry; sur une periode de 10 ans. Dans cette peri o d e;les donnees classiques de la litterature sont retrouvees : frequence elevee des lesions dermatologiques evoluees atteignant de volumineuses tumeurs royales; des crises epileptiques sous toutes ses formes et les complica-tions diverses en raison du retard du diagnostic. Nos resultats soulignent la necessite de suivi et de surveillance de ces patients par un examen somatique (neurologique; ophtal- mologique) et un examen scannographique dicte par les donnees cliniques
