Multicenter Study Clinical Trial
Nefazodone for chronic daily headache prophylaxis: an open-label study.
To assess effectiveness, tolerability, and safety of nefazodone as a prophylactic agent for chronic daily headache. ⋯ These results provide preliminary support for the efficacy of nefazodone in the prophylaxis of chronic daily headache. In this sample, nefazodone was safe and generally well tolerated. Patient ratings of sexual function improved over the course of treatment, in contrast to what is generally observed with most antidepressants. Nefazodone may be particularly beneficial for patients with chronic daily headache and comorbid depression. Further research is indicated.

To empirically test a clinical prediction rule for evaluating HIV-infected patients complaining of headache and to identify those at low risk for intracranial mass lesion who do not need immediate computed tomography of the head. ⋯ Most HIV-infected patients with headache may be treated with analgesics and followed up clinically. Those without focal neurological signs, altered mental status, seizure, or decreased CD4 lymphocytes are unlikely to have intracranial mass lesions.

The present study compared the responses of women with headache (chronic tension-type, n = 27; migraine, n = 27) and controls (n = 27) to an acute pain laboratory task, the cold pressor test. Participants' pain perception (i.e., threshold and tolerance) and their fear/anxiety associated with pain were assessed during days 1, 2, or 3 of menses. Analyses pertaining to participants' responses to the cold pressor test (ie, pain threshold and tolerance) failed to show statistically significant group differences, even when covarying pain-related anxiety/fear. ⋯ Correlational analyses also revealed that cognitive anxiety, somatic anxiety, fear, and escape/avoidance were all significantly correlated with pain tolerance in the group with chronic tension-type headache, but not in the other two groups. Subsequent multiple regressions, however, showed that the relationship between anxiety and pain tolerance was primarily a function of somatic anxiety. These results suggest that headache frequency plays a role in mediating the relationship between fear of pain and pain tolerance and that the models by Lethem and colleagues and McCracken may be relevant for understanding tension headache sufferers' responses to head pain.
