Randomized Controlled TrialNeuroprotective impact of a vitamin trace element composition - a randomized, double blind, placebo controlled clinical trial with healthy volunteers.
Neurotoxic metabolites and oxidative and nitrosative stress reactions play a crucial role in the pathways leading to neuronal cell death and neurodegeneration. The bioavailability of the many antioxidant ingredients a vitamin and trace element composition was investigated, to reveal the neuroprotective (preventive) potential of the composition. ⋯ The observed metabolic changes and alteration of the oxidative status after 3 and six month of regular intake underlines the compositions' potential to ameliorate neurodegenerative processes. We conclude that the subsitution of vitamins and trace-elements with natural source in a proper manner may be effective for neuroprotection in healthy population.

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.

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 TrialEfficacy of repetitive transcranial magnetic stimulation for the treatment of refractory chronic tinnitus: a randomized, placebo controlled study.
The pathophysiologic mechanisms of idiopathic tinnitus remain unclear. Low frequency rTMS applied over the auditory cortex has been proposed as a new and causally oriented treatment approach for pathological conditions with abnormal, increased cortical activity including tinnitus with increased activity in the auditory cortex. However available studies are characterized by a positive reports on the therapeutic effects of repetitive transcranial magnetic stimulation (rTMS) for treatment of tinnitus, there are few details about the duration of specific treatment effects. ⋯ The principal finding of this study is that real 1 Hz rTMS treatment was capable of significantly reducing the total baseline score of basic scales that measure tinnitus severity. This result is important as it proves that significant reduction of symptoms can be achieved even in a group of patients with long-term symptoms resistant to pharmacological treatment.

Randomized Controlled TrialThe epidural steroids in the prevention of epidural fibrosis: MRI and clinical findings.
Epidural fibrosis (EF) represents a frequent and poorly manageable complication of lumbar disk surgery. ⋯ The application of ES did not prove to be useful in the prevention of Failed Back Surgery Syndrome and epidural scar formation. Postoperative pain was decreased in the steroid treated group during the first postoperative week, but not 12 months postoperatively.
