Review Case Reports
Familial trigeminal neuralgia: case reports and review of the literature.
The paroxysmal facial pain of trigeminal neuralgia is usually idiopathic, but familial cases have been described. We describe a family with apparent autosomal dominant transmission of trigeminal neuralgia. Our cases and a review of the literature suggest that the etiology of trigeminal neuralgia may be vascular compression of the fifth cranial nerve. Autosomal dominant vascular and epileptic disorders are reviewed, and possible relationships to familial trigeminal neuralgia are considered.

Comparative Study
Confirmation of the distinction between chronic migraine and chronic tension-type headache by the McGill Pain Questionnaire.
To investigate if the McGill Pain Questionnaire confirms the distinction between chronic migraine and chronic tension-type headache. ⋯ In the disorders characterized by a daily and near-daily headache, the McGill Pain Questionnaire consistently can discriminate between those evolving from migraine and those evolving from tension-type headache, indirectly confirming the validity of a distinction between these 2 clinical conditions. The differences are similar to those observed between patients with migraine and patients with episodic tension-type headache. This seems to be independent of the pain level since the difference of the total pain-rating index and the visual analog scale between chronic migraine and chronic tension-type headache was not statistically significant.

To investigate potential differences in various aspects of personality in women with migraine with aura, without aura, and in healthy volunteers. ⋯ Our results suggest that migraineurs with aura differ from migraineurs without aura and healthy control subjects in terms of anxiety and depression. With regard to health-related locus of control, there was no correlation among mean number of migraine attacks per year, duration of disease, time of last migraine attack, and number of aura symptoms.

The overuse of short-acting barbiturate medications for the acute treatment of headache is a common problem in the United States. Most experts agree that withdrawal from these medications is necessary for subsequent headache treatment to be successful, yet there are few published articles outlining effective methods of drug withdrawal. ⋯ Management of butalbital withdrawal can be simplified by using a phenobarbital-loading protocol, taking advantage of the natural tapering afforded by the drug's long half-life. This method possesses most of the characteristics of an ideal drug withdrawal program for patients with headache who are overusing medications.

The neurotoxin, botulinum toxin type A, has been used successfully, in some patients, as an analgesic for myofascial pain syndromes, migraine, and other headache types. The toxin inhibits the release of the neurotransmitter, acetylcholine, at the neuromuscular junction thereby inhibiting striated muscle contractions. In the majority of pain syndromes where botulinum toxin type A is effective, inhibiting muscle spasms is an important component of its activity. ⋯ These findings suggest that botulinum toxin type A blocks peripheral sensitization and, indirectly, reduces central sensitization. The recent hypothesis that migraine involves both peripheral and central sensitization may help explain how botulinum toxin type A inhibits migraine pain by acting on these two pathways. Further research is needed to determine whether the antinociceptive mechanism mediated by botulinum toxin type A affects the neuronal signaling pathways that are activated during migraine.
