[Perineoscrotal gangrene after a snake bite: a case report]. / Un cas de gangrène périnéoscrotale consécutive à une morsure de serpent.

The authors describe a case of perinoscrotal gangrene in a patient who had been bitten by a snake. He was treated with antivenom immunotherapy and surgery. The outcome was good. They present a brief review of the literature regarding the epidemiological, clinical, and treatment issues.

[Intracranial empyemas: Epidemiological, clinical, radiological and therapeutic aspects. Retrospective study of 100 observations]. / Les empyèmes intracrâniens : aspects épidémiologiques, cliniques, paracliniques et thérapeutiques. Étude rétrospective de 100 observations.

INTRODUCTION: Intracranial empyema is a frequent complication of ear-nose-throat (ENT) infections. Limited studies have been carried-out on cerebral empyema during recent years in Senegal. Despite new imaging techniques, diagnostic and therapeutic problems as well as outcome still remain in our regions. We report our experience compared to that of the literature. The study focused on epidemiological aspects, difficulties in diagnosis and treatment as well as prognosis of this condition. METHODS: This was a retrospective study conducted from January 2008 to December 2011 of 100 clinical cases. Diagnosis was made based on contrast CT-scan. Twenty-one percent of patients received medical treatment alone, while 79% underwent surgery. The duration of the treatment varied from 4 to 8 weeks. The follow-up was clinical and radiological with a mean follow-up time of 12 months. RESULTS: Cerebral empyema represented 44.4 % of all intracranial suppuration cases and the mean age was 21 years. The etiology was ENT in 35%, meningitis 10%, unknown 25%. Localization was sub-dural in 57%, extra-dural in 22%, inter-hemispheric in 10% of the cases. Empyema was associated with an abscess in 7 cases. One case was located in the posterior fossa. The evolution was favorable in 78% of the cases and in 12.5% some neurologic sequelae were observed. Eleven patients died and 3% of the patients had recurrences. CONCLUSION: The frequency of intracranial empyema is still high in Senegal. Difficulties in diagnosis, therapeutics and low economic incomes account for the gravity of intracranial empyema. In spite of these risks, early stage and effective treatment is necessary to reduce the morbi-mortality, especially in young aged children.
