Randomized Controlled Trial
Ketamine does not reduce postoperative morphine consumption after tonsillectomy in children.
Tonsillectomy is one of the most frequently performed operations in children and frequently associated with moderate-to-severe pain. ⋯ The addition of ketamine 0.25 mg/kg at induction of anesthesia did not decrease postoperative morphine consumption in children undergoing tonsillectomy.

Randomized Controlled Trial
Multidisciplinary rehabilitation treatment of patients with chronic low back pain: a prognostic model for its outcome.
(1) To determine if treatment outcome in chronic low back pain can be predicted by a predefined multivariate prognostic model based on consistent predictors from the literature and (2) to explore the value of potentially prognostic factors further. ⋯ The results of this study do not support the construction of a clinical prediction model. Future confirmative studies of homogeneous rehabilitation treatments and outcome measures are needed to shed more light on relevant prognostic factors.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Treatment expectancy and credibility are associated with the outcome of both physical and cognitive-behavioral treatment in chronic low back pain.
Patients' initial beliefs about the success of a given pain treatment are shown to affect final treatment outcome. The Credibility/Expectancy Questionnaire (CEQ) has recently been developed as measure of treatment credibility and expectancy. ⋯ Although the associations found were low to modest, these results underscore the importance of expectancy and credibility for the outcome of different active interventions for CLBP and might contribute to the development of more effective treatments.

Randomized Controlled Trial Clinical Trial
Acupuncture for treatment of persistent arm pain due to repetitive use: a randomized controlled clinical trial.
To compare true and sham acupuncture in their abilities to relieve arm pain and improve arm function in individuals with arm pain due to repetitive use. ⋯ Sham acupuncture reduced arm pain more than true acupuncture during treatment, but the difference did not persist after 1 month. Mild side effects from true acupuncture may have blunted any positive treatment effects. Overall, this study did not find evidence to support the effectiveness of true acupuncture in treatment of persistent arm pain due to repetitive use.

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.
