[Common migraine. Changes in conjugated and unconjugated catecholamines].

Plasma levels of conjugated and unconjugated catecholamines were measured in 27 migraineurs between attacks, in 9 migraineurs 1 to 2 hours after the onset of an attack, and in 30 controls. There were no significant changes in conjugated catecholamines; in contrast, a significant rise (p less than 0.01; KS test) in unconjugated dopamine, noradrenaline and adrenaline levels was observed during attacks. These results confirm that migrainous attacks are associated with platelet activation and with overactivity of the sympathetic system.

[Dermatopolymyositis during desensitization with candidin].

A dermatopolymyositis observation is reported. An urticaria has preceded the dermatopolymyositis and has been treated by a desensitivity procedure. The possible connection between this treatment and the dermatopolymyositis occurring is debated. This observation gives the opportunity to point out the importance of a thorough knowledge of the phenomena involved by such a treatment.

[Alcohol and urticaria].

The relationship of alcohol intake and urticaria is complex. The mechanism of action may be related to a hypersensitivity reaction to ethyl alcohol or to the other components of alcoholic drinks. Urticaria may also result from the pharmacological effects of alcohol or from the histamine content of the drink. The authors review the literature about hypersensitivity to alcohol and to the different components of alcoholic drinks, especially added compounds. The appropriate sensitivity tests for making this diagnosis are described.

[Histamine-release and migraine].

Some studies suggested a role for histamine in the pathogenesis of the migraine. So we decided to investigate the histamine-release in two groups of patients: 8 common migraine patients, 8 healthy subjects. Plasma from either controls or migraineurs were mixed with the same control whole blood and histamine release was measured using a radio-enzymatic assay. Migraine plasma induced an histamine release significantly more important than control plasma (p less than 0.01). The nature of an "histamine releasing factor" in the plasma of migraine patient is discussed. This work is an argument for a possible immuno-allergic process in migraine.
