[Quality of life and multiple sclerosis: validation of the french version of the self-questionnaire (SEP-59)].

We conducted a prospective study among 166 multiple sclerosis (MS) patients (103 from an university hospital, 63 from a MS rehabilitation center) to assess the properties of the French version of the Multiple Sclerosis Quality Of Life - 54 items (MS QOL-54) which combines the MOS SF36 together with MS specific items. The SF-36 had been translated into French through the IQOLA project. We translated and adapted the MS specific items with the help of three different teams. The translation into French has an addition of five items, because we kept the MS specific items of an earlier unpublished form. Acceptability is excellent with a response rate over 90p.100. Test-retest reliability is good except for the "role limitation-emotional" scale of the SF-36. Construct validity, based on factor analysis, shows no change in the SF-36 internal consistency and the specific items provided their own information. External validity, tested against both medical (Expanded Disability Status Scale, Kurtzke scale, Mini-Mental-State and disease stage) and rehabilitation (Functional Independence Measure) parameters is excellent. The French MS QOL questionnaire contains 59 items including both the SF-36 and the MS QOL-54 items. This will permit international comparisons of MS patients' care and therapy.

[Neurogenic muscle hypertrophy: 3 cases].

Three cases of neurogenic muscular hypertrophy are reported. First case presented a hypertrophy of one calf following S1 radiculopathy; the second had a hypertrophy of tibialis anterior muscle, five years after a compressive injury of the common peroneal nerve. The third case is a global hypertrophy of leg muscles after intensive care or legionella neuropathy. Previous cases of the literature are reviewed and the various pathophysiological hypothesis are considered. Among these hypothesis, the role of abnormal electrophysiological activities in most previous cases, as well as in ours (namely complex repetitive discharges and fasciculations), seems the most consistent.

[Isolated proximal muscular weakness disclosing myasthenic syndrome].

Three cases of chronic limb-girdle myasthenia gravis (one man and two women) are reported. The duration of the disease was three, five and 20 years respectively. None had oculobulbar weakness during this period nor fluctuating symptoms. The primary diagnosis was myopathy in two cases and myelopathy in the other one. In view of this diagnosis, several features were atypical: absence of marked wasting, preservation of tendon reflexes and normal serum creatine kinase activity. Finally, diagnosis of myasthenia gravis was established by the occurrence of a characteristic decremental muscular response to repetitive stimulation and by positive edrophonium test. It seems that the rate of positivity of acetylcholine receptor antibody is lower than in the common form of the disease. Two patients responded to acetylcholinesterase inhibitors and one to high-doses intravenous human immunoglobulins. These and previous cases described in the literature raise the problem of the definition of an unusual form of myasthenia gravis or of a new type of neuromuscular disease characterized by the presence of distinctive changes on muscular biopsies, specially tubular aggregates as in one of our cases. However, this unusual form of chronic limb-girdle weakness has to be recognized because treatments are effective in most cases.

[Polymyalgia induced by topical minoxidil].

Topical minoxidil, used in the treatment of baldness, has been commercially available since 1987. Its systemic side effects are rare. We observed an as yet unreported "polymyalgia syndrome" in four otherwise healthy males whose sole medication was topically applied minoxidil. They experienced fatigue, weight loss and severe pain in the shoulders and pelvic girdle, suggesting connective tissue disease. Three patients had a transient rise in liver enzymes, while other laboratory analyses remained normal. Tritanomaly was detected in two patients who underwent systematic color vision testing. All symptoms disappeared after withdrawal of minoxidil. Rechallenge was positive once in one patient and twice in another. The mechanism of this side effect remains to be determined.
