RESUMO
BACKGROUND AND OBJECTIVE: Cyclic vomiting syndrome (CVS) is associated with migraine. This study aimed to evaluate the efficacy of sumatriptan in treating CVS. METHODS: Twelve patients were enrolled in this trial. Sumatriptan was administered either subcutaneously [(age x 4 + 20)/100 x 3 mg] or by nasal spray (NS; 20 mg). Response to the treatment was classified as complete, effective, or noneffective. RESULTS: Eleven patients, who presented with 35 attacks, were treated by subcutaneous injection of sumatriptan. The treatment was responsive in 19 attacks. The efficacy of sumatriptan was high in attacks that occurred in cases with a family history of migraine compared to those without (p = .0482). Five patients were treated with sumatriptan NS for six attacks. The treatment was completely responsive in two of six attacks. We observed no adverse effects associated with sumatriptan treatment in this trial. CONCLUSION: We conclude that sumatriptan has potential efficacy in treating of patients with CVS.

Carrier detection for 12 women and prenatal diagnosis for six fetuses in Japanese families with a patient with Menkes disease (MNK) were performed by gene analysis and/or measurement of the copper concentration in cultured cells. Six out of eight mothers of MNK patients were carriers while two (25%) were not carriers. Two unrelated patients showed the same mutation (R986X): one patient's mother was a carrier while the other was not. One male and three female fetuses did not have the same mutant allele as the respective MNK proband and have been healthy since birth. One female fetus had the same mutant allele as her affected brother. Gene analysis is very useful and reliable, although such examination is only indicated in families in which a mutation has been identified. In one family in which a mutation in ATP7A was not found, cultured amniocytes from a male fetus had a high copper concentration. Thus after his birth, the biochemical findings confirmed the presence of MNK and early treatment was started. As his early treatment with parenteral copper-histidine prevented the neurological disorders effectively, prenatal diagnosis is very important.
