RESUMO
In a period of one year (1990) we selected 40 patients suffering from migraine. For an open randomized study there were 2 groups of patients: the first were treated with 10mg of flunarizine per day and the second with 3 mg per day. The patients were treated for 4 months consecutively. There were 11 drop outs (27.5%): nine for poor compliance and 2 due to side effects. The efficacy of flunarizine in the prophylaxis of migraine was essentially identical in the two dosage groups while the incidence of side effects was considerably reduced in the patients treated with the lower dose.

The tarsal tunnel syndrome (TTS) is an entrapment of the posterior tibial nerve at the ankle, which, like carpal tunnel syndrome, improves with surgery but needs an instrumental diagnosis to exclude other diseases. This study was performed to evaluate the diagnostic value of nerve conduction tests proposed for the diagnosis of TTS. Of the 13 patients who were investigated 12 had secondary unilateral and 1 idiopathic bilateral TTS. One or more neurophysiologic parameters were abnormal in all cases. The diagnostic value of each neurophysiologic parameter was calculated by comparing conduction on the affected side with conduction on the healthy side of each patient with TTS. The accuracies of the sensory nerve action potential and mixed nerve action potential, both after stimulation of the plantar nerves, were almost the same, with sensory nerve action potentials more sensitive and less specific and mixed nerve action potentials less sensitive and more specific. Because from the clinical point of view we must be more afraid of false-positive results, the mixed nerve action potential is recommended for presurgical diagnosis of TTS. Coexistence of mixed nerve and sensory nerve action potential abnormalities, especially if asymmetric, are highly indicative of TTS.
