Randomized Controlled Trial
Acupuncture in migraine prevention: a randomized sham controlled study with 6-months posttreatment follow-up.
To assess the efficacy of acupuncture in migraine prophylaxis. ⋯ Individualized treatment based on traditional Chinese medicine plays a role in preventing migraine attacks. Nevertheless, sham acupuncture had similar effects. Major conclusions were limited by the small sample sizes however the observed trends may contribute to design future trials.

Randomized Controlled Trial Multicenter Study
Acupuncture in migraine: investigation of autonomic effects.
A dysregulation of the autonomic nervous system is discussed as a pathogenetic factor in migraine. As acupuncture has been shown to exhibit considerable autonomic effects, we tested whether the clinical effects of acupuncture in migraine prophylaxis are mediated by changes of the autonomic regulation. ⋯ The data indicate, that VA and SA acupuncture might have a beneficial influence on the autonomic nervous system in migraineurs with a reduction of the LF power of HRV related to the clinical effect. This might be due to a reduction of sympathetic nerve activity. VA and SA induce different effects on the high-frequency component of HRV, which seem, however, not to be relevant for the clinical outcome in migraine.

Randomized Controlled Trial
Mirtazapine decreases the pain feeling in healthy participants.
The treatment of neuropathic pain is mainly based on antiepileptics, tricyclic antidepressants, and opiates. These drugs have important side effects disturbing the patient's quality of life. Mirtazapine (MTZ) is a new and well-tolerated tricyclic antidepressants with both monoaminergic and opioid properties that might favorably influence pain. The aim of this study was to assess whether MTZ can reduce the pain induced by a standardized stimulus presented to healthy human participants. The nociceptive flexion reflex (NFR) to an electric stimulus was chosen to determine the pain threshold. ⋯ MTZ increases the pain tolerance in healthy participants. The potential benefit of this effect on pain should be investigated more thoroughly in chronic neuropathic pain patients. The NFR might serve as an additional tool for the monitoring of these patients.
