SummaryIn this double-blind, four-week study, 28 chronic schizophrenic patients receiving neuroleptic medication plus the antiparkinsonian drug, benztropine mesylate, were either switched to placebo or maintained on benztropine. Patients withdrawn from benztropine reliably increased their overall scores on the Wechsler Memory Scale in comparison with the drug group. Sub-test scores suggest that deficits in attention and concentration were induced by treatment with benztropine. Psychotio decompensation appeared to develop simultaneously with extrapyramidal symptoms (EPS) in some patients, but only 14.2 per cent of the placebo group experienced extrapyramidal symptoms severe enough to require resumption of benztropine therapy. It is suggested that antiparkinsonian agents should be prescribed only if and when EPS occur.

The fear of postoperative pain is often mentioned by patients as one of the factors that is most frequently associated with dental implants. To reduce this factor, a single oral dose of 25 mg dexketoprofen trometamol (DKT) or placebo was administered 15 minutes before implant surgery. One hundred patients who required single-implant treatments were randomly assigned to 1 of 2 blinded groups. The patients in the test group were given 25 mg DKT (DKT group), and those in the control group were given 500 mg vitamin C as a placebo (PLACEBO group). A subjective visual analogue scale of 100 mm in length was used to evaluate pain. Inflammation and complications were assessed using a 5-point Likert scale. An analysis of variance, t-tests, and a Mann-Whitney U test were performed. Among the 100 patients, 83 completed the study (there were 8 dropouts in the PLACEBO group and 9 in the DKT group). The patients who received DKT reported a lower pain intensity during the immediate postoperative period. The inflammatory response was weaker in the DKT group than the control group at 48 hours, but bleeding was greater. There were no other complications in either of the groups. In conclusion, the preemptive use of 25 mg soluble DKT administered orally 15 minutes before implant surgery can reduce the severity of immediate postoperative pain.

Abstract Context Polycystic ovary syndrome (PCOS) is the most common endocrinopathy affecting women of reproductive age. Objective This study was designed to evaluate effects of lifestyle modifications and synbiotic supplementation on PCOS. Design A randomized (1:1) double-blind, placebo-controlled trial. Setting Academic hospital. Patients or Other Participants Overweight and obese women with PCOS were identified according to the Rotterdam criteria. Evaluations were performed at baseline and repeated after 3 months of treatment. Intervention Lifestyle modifications in combination with synbiotic supplementation or placebo. Main Outcome Measures Change in BMI and testosterone level. Results In the Placebo Group, a 5% decrease in BMI was accompanied by significant decreases of the waist, hip, and thigh circumferences. The Synbiotic Group experienced an 8% decrease in BMI, which was significantly greater than that in the Control Group (P=0.03) and was accompanied by decreases in the waist, hip, and thigh circumferences. Testosterone did not decrease significantly in the Placebo Group (decrease of 6%), while in the Synbiotic Group it decreased by 32% (P&lt;0.0001). The decrease of testosterone was significantly greater in the Synbiotic Group than in the Placebo Group (P=0.016). Conclusions Synbiotic supplementation potentiated effects of lifestyle modifications on weight loss and led to significant reduction of serum testosterone.

SummaryA double blind, placebo controlled trial was carried out to examine the contribution of propranolol as an adjunct to neuroleptic medication in the treatment of chronic schizophrenic patients whose florid symptoms had not remitted with neuroleptic medication alone. Propranolol was shown to have a more beneficial effect than placebo, but the results were much less dramatic than those which have been described in previous studies. Recent work has shown that there may be a pharmacokinetic interaction between propranolol and neuroleptics, and this should be considered as one possible explanation of our findings.

Objective. This study was a multicenter, randomized, double-blind, and controlled trial with two parallel arms: the GJBNH group and the placebo group. This trial recruited 100 women aging 18 to 35 years with primary dysmenorrhea caused by blood stagnation. The investigational drugs, GJBNH or placebo, were administered for two menstrual periods (8 weeks) to the participants three times per day. The participants were followed up for two menstrual cycles after the administration.Results. The results were analyzed by the intention-to-treat (ITT) dataset and the per-protocol (PP) dataset. In the ITT dataset, the change of the average menstrual pain VAS score in the GJBNH group was statistically significantly lower than that in the control group. Significant difference was not observed in the SF-MPQ score change between the GJBNH group and the placebo group. No significant difference was observed in the PP analyses. In the follow-up phase, the VAS scores of the average menstrual pain and the maximum menstrual pain continually decreased in the placebo group, but they increased in the GJBNH group.Conclusion. GJBNH treatment for eight weeks improved the pain of the dysmenorrhea caused by blood stagnation, but it should be successively administered for more than two menstrual cycles.Trial Registration. This trial is registered with Current Controlled Trials no.ISRCTN30426947.

SummaryIn a double-blind comparative trial of sulpiride (600–1,800 mg/day) and trifluoperazine (15–45 mg/day) in 38 chronic schizophrenic patients, ratings of therapeutic results and unwanted effects were made at two-weekly interviews during the six weeks treatment period. The results show that sulpiride has neuroleptic properties and a spectrum of therapeutic activity similar to that of trifluoperazine. There was an association between plasma sulpiride levels and therapeutic response after four weeks' treatment.

Abstract Background: Migraine is a common type of primary headache that is highly disabling and is possibly associated with obesity. Increasing body mass index (BMI) seems to be a risk factor for migraine attacks. Cinnamon has anti-inflammatory, neuroprotective, and anti-obesity effects. Thus, this study aimed to assess the effects of cinnamon on anthropometry status and headache disability of migraine patients.Methods: Fifty patients with migraine were randomized to receive either cinnamon powder, three capsules/day each containing 600 mg of cinnamon or three placebo capsules/day each containing 100 mg of corn starch (control group) for two months. Height, body weight (BW), waist circumference (WC), and hip circumference (HC) were measured at baseline and the end of the study. Furthermore, Minimal or Infrequent Disability (MIDAS) and Headache Daily Result (HDR) Questionnaire were recorded. Results: After follow-up, BW and BMI did not change in the intervention group, however, both of them significantly increased in the placebo group. The differences between the two groups were statistically significant (p=0.001). WC significantly decreased in the cinnamon group and remarkably increased in the control group; the difference between groups was significant (p<0.001). Furthermore, HC and WHR significantly decreased in the intervention group than the placebo group (p=0.001). HDR and the total score of disability in migraine patients were significantly decreased in the intervention versus the control group (p<0.001). Conclusion: Cinnamon seems to have beneficial effects on BW, BMI, WC, and HC and it reduces the headache disability of migraine patients. More randomized controlled trials should be undertaken to confirm these effects.

Background: Bacterial vaginosis (BV) is a clinical syndrome caused by the changing of Lactobacillus spp., a producer of hydrogen peroxide, in the normal vagina with a high concentration of anaerobic bacteria, Gardnerella vaginalis and Mycoplasma hominis. This study reports a resistance of BV therapy regimens, high recurrence rates, and side effects of an antibiotic. Therefore, adjunctive therapy for BV management is needed. Research has reported the therapeutic effects of probiotic in BV; however, the results are inconsistent. Purpose: To evaluate the efficacy of standard therapy using metronidazole and Lactobacillus plantarum for BV measured by the cure rate and vaginal flora balance. Methods: A randomized, double-blind, placebo-controlled trial, 30 subjects were randomized to take metronidazole 500 mg twice a day for seven days with weekly evaluation. The Lactobacillus plantarum or placebo group was evaluated every 4 weeks. The cure rate and vaginal flora balance were evaluated using the Amsel criteria and Nugent score before and after the intervention. Result: A total of 30 subjects returned for 28-day follow-up, of which 60% subjects of the antibiotic/probiotic group were cured compared to 40% in the antibiotic/placebo group (p>0.05). Conclusion: There was no difference in the increase of cure rate and vaginal flora balance between the treatment group and significant control group.

Objective: Osteoarthritis is a degenerative disease of the joints. Non-steroidal antiinflammatory drugs (NSAIDs) are being used for the treatment of osteoarthritis. However, their use is limited due to complications, such as gastrointestinal bleeding. Therefore, it is necessary to find alternative treatments for osteoarthritis. Recently, nanomicelle curcumin has been developed to increase the oral bioavailability of curcumin. The aim of this study was to evaluate the effect of nano curcumin on the alleviation of the symptoms of knee osteoarthritis patients. Methods: In this randomized, double-blind controlled trial, the intervention group was administered 40 mg of nanocurcumin capsule every 12 hours over a period of six weeks, and the control group received the placebo (similar components of nanomicelle curcumin capsules yet without curcumin). In the final analysis, 36 patients in the nanocurcumin group and 35 patients in the placebo group were enrolled. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) was filled for patients in their first visit and at the end of six weeks. Differences were statistically significant at P-value < 0.05. Results: There were no significant differences between the two groups regarding gender, age, Kellgren score, and the duration of the disease before the intervention. A significant decrease was observed in the overall score, along with the scores of pain, stiffness and physical activity subscales of the WOMAC questionnaire in patients of the nano curcumin group compared with the placebo group. Conclusion: Nanocurcumin significantly improves the symptoms of osteoarthritis patients.
