A Canadian population survey on the clinical, epidemiologic and societal impact of migraine and tension-type headache.

Trained telephone interviewers contacted 1,573 adults across Canada about the nature and frequency of headaches suffered by them or by others in their households. Using a table of pain symptoms and other characteristics abstracted from the International Headache Society (IHS) classification, the headaches were assigned to migraine headache, tension-type headache or other diagnostic groups. Of the households sampled, 59% had at least one headache sufferer in residence. The proportion of headache sufferers with migraine was 14%; with tension-type, 36%; and with both, 14%. Migraine headache caused more disability than tension-type headache, with nearly 20% of migraine sufferers taking time off work and disability lasting for a mean of 1 day. It is concluded that the current prevalences of migraine and tension-type headache in Canada fall around the mean of previous studies, that the IHS criteria can form a basis for diagnostic classification and that the functional impact of migraine has been seriously underestimated in the past.

Additions to the myotonic dystrophy linkage group.

One hundred and thirty members of a family with 33 cases of Dystrophia myotonica (Dm) were tested for various genetic markers including Km, Jk, Lu and Se. All individuals tested were Lua negative, but many were heterozygous for the other markers. Except for two cases all patients with Dm were positive for Km3 and Jka and they were secretors. Assuming the genes are linked and that the order of the loci is Km, Jk, Lu, Se, Dm, then there were 22 meioses informative for Dm and in 10 of these a recombination must have occurred between two of the five loci. Looking at individual pairs of loci, there were no recombinations between Km and Jk in seven informative meioses, three recombinations out of 10 meioses informative for Jk/Se, no recombinations between Se and Dm in five informative meioses and three recombinations out of 12 meioses informative for Jk/Dm.

Treatment of carotid cavernous fistula by intravascular occlusion using a balloon catheter.

The surgical treatment of carotid cavernous fistula gradually evolved into a "trapping" technique. This technique includes ligation of the cervical internal carotid artery, clipping of the intracranial portion distal to the fistula and often embolization of the isolated segment. The development of embolization techniques using intravascular balloon catheters greatly simplified this treatment. The authors report a case of spontaneous carotid cavernous fistula in which obliteration was achieved by an intracarotid balloon catheter. This was inserted by direct puncture of the carotid artery, which had been exposed by a simple neck incision. The patient's visual acuity was preserved. The efficacy, ease and safety of this method are emphasized.
