Neurosyphilis accounts for 56%-70% of all visceral syphilis and is a complication in 5%-10% of cases of untreated syphilis. The aim of this study was to evaluate the epidemiological aspects and clinical presentations of neurosyphilis in Morocco through a series of 201 patients attending the Centre for Neurological Services at the university hospital in Rabat between 1986 and 1997. The mean age of the patients was 41.26 (SD 9.23) years (range: 17-70 years); the majority (91%) were male. The incidence of neurosyphilis in Morocco is high. From 31 cases per year in 1985, it has fallen since 1990 to reach 10 cases in 1997. Among the different clinical presentations recorded, chronic meningoencepahalitis was the commonest, followed by meningovasculitis, tabes dorsalis and optic atrophy.

Introduction: Benign intracranial hypertension (BIH) or pseudotumor cerebri is diagnosed on the basis of Dandy's criteria. BIH creates an emergency situation because of the risk of lost vision. In this work, we studied retrospectively a series of 10 cases of BIH all meeting Dandy's criteria. Our objective was to assess the benefit of the corticosteroid-acetazolamide combination on clinical course, especially on papiledema., Methods: Eighty-four patients were hospitalized at the neurology department (Hopital des Specialites, Rabat) over a period of 14 years (1988-2001). They were divided into three groups: forty cases of cerebral thromophlebitis, 10 cases of BIH. In the remaining 34 cases, the investigations were insufficient, so that Dandy's criteria could not be verified. We studied only the 10 cases presenting with a diagnosis of BIH diagnosis complying with Dandy's criteria. The patients underwent a physical examination, cerebral magnetic resonance imaging (MRI) if possible or CT scan with conventional angiography, and CSF examination with pressure measurement. We analyzed age, sex-ratio, clinical aspects and the outcome after treatment. The major criterion of outcome was the regression of papilledema., Results: There were 9 women and 1 man. The mean age was 24.6 8.4 years. Behcet's disease was noted in 3/10 patients. The clinical features were those described in the literature. Patients were treated by corticosteroids combined with acetazolamide and CSF depletion in all cases. CSF derivation was performed in only 1 patient. Definitive blindness was noted in 2 patients at admission. A favorable course was noted in 8/10 cases, with regression of papilledema within approximately 1 month., Discussion: We suggest that the corticosteroid-acetazolamide combination can have a beneficial effect on papilledema in BIH. However, these results should be confirmed by a prospective, randomized, double blind controlled study.

A 25-year-old male presented purulent meningitis associated with transverse myelitis. Spinal T2-weighted MRI showed a large spinal cord with an intramedullary high signal. Infection resolved with antibiotic therapy but spastic paraplegia persisted. Four months later, he developed a Guillain-Barré syndrome with clinical and biological signs of systemic lupus erythematosus. Final outcome was fatal despite corticosteroid and immunoglobulin treatment.

Introduction: Neurological manifestations in Behçet's disease usually consist of meningoencephalitis and cerebral thrombophlebitis. Myelitis is rare, especially when it is the only neurological manifestation., Exegesis: The authors report three cases of acute myelitis complicating Behçet's disease demonstrated by magnetic resonance imaging. In two cases, Behçet's disease was revealed by myelitis. The three cases were transverse myelitis, two of which were juvenile Behçet's disease and two were meningomyelitis., Conclusion: Magnetic resonance imaging can help guide diagnosis of myelitis in Behçet's disease. It can also be useful to assess the results of the treatment. Clinical symptoms of Behçet's disease must be searched for in the case of myelitis, especially for patients from Mediterranean countries.
