[Primary mixed unilateral algias (author's transl)].

Usually trigeminal neuralgia or tic douloureux and migrainous neuralgia or cluster headache are sharply opposed. But some rare cases of mixed facial unilateral algias associating both mechanisms are possible. Here is studied a series of 12 cases. One may distinguish: 1. one neuralgic vascular type. It starts by lightning and triggered hemifacial pain followed by tenderness and vaso-secretory phenomenous of same topography; 2. the second is of vascular-neuralgic type. It starts like common cluster headache; the lightning pain occuring in the end of paroxysm. Only the first type -- neuralgic vascular -- is reactive to chimiotherapy (carbamazepine) or local antinevralgic procedures (thermocoagulation).

[Headache of cervical origin. Critical study (author's transl)].

When confronted to an occipito-cervical headache too often cervical etiology is proposed. Several cervical mechanisms are however possible: 1) neuralgic mechanism for the three first cervical segments. Any vertebral or intra-spinal lesion may affect the first three posterior roots; 2) muscular mechanism affecting cranio-cervical muscles: role of posture; spinal unbalance; traumatic or acute rheumatic discovertebral lesion; 3) vascular (arterial) mechanism, much more unfrequent like vertebro-basilar insufficiency. The role of vegetative (sympathetic) system is practically inexistant. So cervicarthrose play no role when there is no arthro-muscular involvement with painful limitation of cervical movements. But the most important causes of posterior cephalalgia are not of cervical intracranial origin: they are tumours of posterior fossa; high blood pressure, and above all tension headache of psychic origin.
