RESUMO

This article describes the context in which 3,4-methylenedioxyamphetamine (MDA), 3,4-methylenedioxymethamphetamine (MDMA) and other mescaline-like compounds were explored as hallucinogens for military and intelligence purposes from the 1940s to the 1960s. Germans first tested mescaline as a "truth drug" in a military context. In the 1940s, the United States military started testing hallucinogenic substances as truth drugs for interrogation and behavior manipulation. After tests carried out using mescaline and other drugs in 1950, some derivatives of mescaline were synthesized by the Army for the exploration of possible "speech-inducing" effects. After insufficient animal testing, the substances were given to patients at the New York State Psychiatric Institute (NYSPI). 3,4-Methylenedioxy-N-ethylamphetamine (MDE), a compound almost identical to MDMA, was among the compounds delivered for testing at the NYSPI. During tests with other derivatives (3,4-dimethoxyphenethylamine (DMA), 3,4-methylenedioxyphenethylamine (MDPEA), MDA) in 1952-53, an unwitting patient died in these tests, which was kept secret from the public. Research was interrupted and toxicological animal testing procedures were initiated. The secret animal studies run in 1953/1954 revealed that some of the "mescaline derivatives" tested (e.g. MDA, MDE, DMA, 3,4,5-trimethoxyamphetamine (TMA), MDMA) were considered for further testing in humans. In 1955, the military changed focus to lysergic acid diethylamide (LSD), but some interest in mescaline-like compounds remained for their ability to change mood and habit without interfering with cognition and sensory perception. Based on the known documents, it remains unclear (but probable) whether any of the mescaline derivatives tested were being used operationally.

RESUMO

It is known from clinical studies that some patients attempt to cope with the symptoms of post-traumatic stress disorder (PTSD) by using recreational drugs. This review presents a case report of a 19-year-old male patient with a spectrum of severe PTSD symptoms, such as intense flashbacks, panic attacks, and self-mutilation, who discovered that some of his major symptoms were dramatically reduced by smoking cannabis resin. The major part of this review is concerned with the clinical and preclinical neurobiological evidence in order to offer a potential explanation of these effects on symptom reduction in PTSD. This review shows that recent studies provided supporting evidence that PTSD patients may be able to cope with their symptoms by using cannabis products. Cannabis may dampen the strength or emotional impact of traumatic memories through synergistic mechanisms that might make it easier for people with PTSD to rest or sleep and to feel less anxious and less involved with flashback memories. The presence of endocannabinoid signalling systems within stress-sensitive nuclei of the hypothalamus, as well as upstream limbic structures (amygdala), point to the significance of this system for the regulation of neuroendocrine and behavioural responses to stress. Evidence is increasingly accumulating that cannabinoids might play a role in fear extinction and antidepressive effects. It is concluded that further studies are warranted in order to evaluate the therapeutic potential of cannabinoids in PTSD.

RESUMO

Previous studies reported that respiratory feedback (RFB) aids in alleviating chronic pain. However, to date, this adjunct treatment has not been rigorously tested against non-contingent (placebo) feedback. Forty-two patients with chronic low back pain were randomized to either RFB or non-contingent RFB. Both groups performed a daily 30-min home training for 15 consecutive days. A respiratory associated relaxation index (RI) was measured. Pain levels and a somatosensory profile were assessed before and after intervention. Additionally, pain levels were assessed 3 months after the end of intervention. Secondary outcome parameters included daily functioning, psychopathology, and suggestibility. T-tests showed higher and significant pain reductions for RFB, compared to non-contingent RFB. Between-group comparisons reached no significance. However, changes were more pronounced in the RFB condition, which was also true for the course of the RI and the psychopathological scores. This is the first study using a non-contingent respiratory placebo feedback in a randomized, controlled design. Within this design previous positive findings of symptom reductions in patients treated with RFB could partially replicated. Nonetheless, tendencies suggest that contingent feedback patients compared to placebo patients profit more from RFB in the long run regarding reduction of chronic pain and psychological distress.

RESUMO

BACKGROUND: In a previous study it has been shown that acupuncture activates the respiratory burst (RB) of neutrophils as measured by the differences to baseline of the mean channel number of fluorescence intensity (mfi) in volunteers. Since this result could have been affected by a placebo effect, a study has been designed that controls for the different facets of placebo mechanisms such as expectancy, suggestibility, and conditioning. PARTICIPANTS AND METHODS: 60 healthy volunteers were randomized either to acupuncture of the acupoint Large Intestine 11 (LI 11) (groups 1 and 2) or relaxation (group 3) twice a week for 4 weeks. Only acupuncture group 1 and the relaxation group were provided with the additional suggestion that the treatment may strengthen the immune system. RESULTS: The repeated measurement analysis for differences of follow-ups to baseline showed significantly different treatment effects for neutrophils but not for monocytes (unprimed neutrophils: p = 0.004; neutrophils primed with TNF-alpha/FMLP or with FMLP only: p = 0.026 and p = 0.019, respectively) between groups. For both cell types post-hoc Dunnett's t-tests using the relaxation group as control showed significantly stronger treatment effects for acupuncture group 1. Combining all priming procedures, the average increase in mfi for both cell types was about 30% greater in acupuncture group 1 than in the relaxation group. Plasma concentrations of pro-inflammatory cytokines only increased significantly in the acupuncture groups. CONCLUSION: Repetitive acupuncture increases the cytotoxicity of leukocytes in healthy volunteers, which might be intensified by a conditioning-expectation effect.

RESUMO

BACKGROUND: In contrast to psychological interventions the usefulness of acupuncture as an adjuvant therapy in rheumatoid arthritis (RA) has not yet been demonstrated. OBJECTIVE: The efficacy of auricular electroacupuncture (EA) was directly compared with autogenic training (AT). METHODS: Patients with RA (n = 44) were randomized into EA or AT groups. EA and lessons in AT were performed once weekly for 6 weeks. Primary outcome measures were the mean weekly pain intensity and the disease activity score 28 (DAS 28); secondary outcome measures were the use of pain medication, the pain disability index (PDI), the clinical global impression (CGI) and pro-inflammatory cytokine levels, which were assessed during the study period and 3 months after the end of treatment. RESULTS: At the end of the treatment and at 3-month follow-up a clinically meaningful and statistically significant improvement (p < 0.05) could be observed in all outcome parameters and both groups. In contrast to the AT group, the onset of these effects in the EA group could already be observed after the 2nd treatment week. In the 4th treatment week the EA group reported significantly less pain than the AT group (p = 0.040). After the end of treatment (7th week) the EA group assessed their outcome as significantly more improved than the AT group (p = 0.035). The erythrocyte sedimentation rate in the EA group was significantly reduced (p = 0.010), and the serum concentration of tumor necrosis factor-alpha was significantly increased compared to the AT group (p = 0.020). CONCLUSIONS: The adjuvant use of both EA and AT in the treatment of RA resulted in significant short- and long-term treatment effects. The treatment effects of auricular EA were more pronounced.

RESUMO

Thirty-four alcoholics were treated with acupuncture to the ear and the body in a randomized single-blind placebo-controlled design over 14 days. Orthodox points and placebo needles to orthodox points were used daily for a total of 10 treatments starting on the first day of admission as add-on therapy to standard medication with carbamazepine. The primary outcome was the Clinical Institute Withdrawal Assessment (CIWA-Ar-scale) assessed on days 1-6, 9 and 14. No initial differences were found regarding sociodemographic data, drinking history and alcohol-related data, indicating successful randomization. Longitudinal analysis of the Clinical Institute Withdrawal Assessment (CIWA-Ar-scale) data showed that patients assigned to acupuncture had a general tendency towards better outcome results and significantly fewer withdrawal symptoms on day 14 (Wilcoxon-W=177.500, Z=-2.009, p = 0.045). No significant differences were found in the Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI X1 and X2) and Eigenschaftswoerterliste (EWL S60). We conclude that acupuncture as an adjunctive treatment to carbamazepine medication shows promise for the treatment of alcohol withdrawal symptoms. Further investigation of this treatment modality appears to be warranted.
