RESUMO
BACKGROUND: Fampridine is a broad-spectrum voltage-dependent potassium channel blocker that enhances synaptic transmission. The drug has been shown to be able to ameliorate conduction in demyelinated axons, thereby leading to improved gait in patients with multiple sclerosis (MS). OBJECTIVE: To assess the "real-life" efficacy and safety of fampridine prescribed for gait disorders in MS. This was an observational and prospective study carried out at MS Units participating in the Brazilian Multiple Sclerosis Study Group. METHODS: Patients with MS and gait disorders were prescribed fampridine (10âmg twice a day), irrespectively of the degree of disability determined by MS. Neurological disability determined by MS was assessed with the expanded disability scale score (EDSS). Outcomes for efficacy and safety of the drug were evaluated by the 25 foot-walk test and by the adverse events of fampridine. RESULTS: The time taken to walk 25 feet decreased by 20% or more in 62 patients (70%). Twenty-five patients were considered to be non-responders to this treatment. Improvement in walking speed was independent of improvement of disability. Mild or moderate adverse events were reported in 8% of patients. CONCLUSION: Fampridine is an efficient and safe therapeutic option for patients with MS and gait disorders.

PURPOSE: Children with cerebral palsy (CP) may present varied ophthalmological problems. Paradoxically, however, investigation of visual function and possible related disorders is not routinely conducted in this population during medical consultations. METHOD: This paper proposes a simple, practical guide for assessing vision and ocular motricity in children with CP. One-hundred and twenty-three patients (mean age: 8.4 years +/- 2.3) from the Sarah Network of Rehabilitation Hospitals (Brasilia, Rio de Janeiro and São Luis units) were studied. Various parameters were investigated (smooth pursuit movements, strabismus, visual acuity, visual field, visuospatial neglect and nystagmus) using the following assessment tools: adapted smooth pursuit test for ocular motricity; Snellen test for visual acuity; confrontation method for visual field; cancellation test (star test) for visual neglect; and cover test for strabismus. Nystagmus was assessed based on patient observation. RESULTS: Eighty-one children completed all the evaluations. Among these, 38 (47%) had no visual problems (hemiplegia 60.5%; diplegia 41.4%; triplegia 12.5%; mixed tetraplegic 33.3%); 23 had difficulties in one of the tested items; and 20 had problems in two or more areas of vision. CONCLUSIONS: Visual and oculomotor tests are of significant importance in children with CP and provide relevant information for creating a rehabilitation programme aimed at the individual as a whole.
