Randomized Controlled Trial"Mesodiencephalic" modulation in the treatment of diabetic neuropathy.
Aim of the study was to verify the efficacy of "mesodiencephalic" modulation (MDM), as named by the commercial promoters, in reducing symptoms accompanying painful diabetic neuropathy and in improving mental health. ⋯ The study did not demonstrate any positive effect of MDM on painful diabetic neuropathy compared to placebo, relative to pain or mental state evaluations. The study emphasizes the need of using placebo-controlled studies, especially when testing a new analgesic drug or a method for pain modulation.

Randomized Controlled TrialRelationship of ketamine's antidepressant and psychotomimetic effects in unipolar depression.
Ketamine and other NMDA (N-methyl-D-aspartate) antagonists produce fast-acting antidepressant-like effects, although the underlying mechanism is unclear. Furthermore, high affinity NMDA antagonists such as ketamine are associated with psychotomimetic effects. To date the link between the antidepressant and psychotomimetic effects of ketamine has not been explored. We examined the relationship between the antidepressant and psychotomimetic effects of a single ketamine infusion in subjects diagnosed with major depressive disorder. ⋯ The substantial relationship between ketamine's antidepressant and psychotomimetic effects was found. This relationship could be mediated by the initial steps of ketamine's action, trough NMDA receptors, shared by both ketamine's clinical effects.
