Of the 195 patients included, 134 (68.7% completed the study. At baseline the two groups were similar, except there was a higher proportion of patients whose episode was severe-DSM IV in the milnacipran group (63.3% versus 54.0% in the venlafaxine group. The initial MADRS score (mean 31.0 decreased progressively during the study, and this decrease was in the two treatment groups (n = 177: 90 milnacipran; 87 venlafaxine at week 24 (observed case/OC, mean change –23.1 milnacipran; –22.4 venlafaxine. The rate of MADRS response (reduction ≥ 50% at week 8 and week 24-last observation carried forward/LOCF was similar in the two groups (week 8: 64.4% milnacipran; 65.5% venlafaxine; week 24: 70% milnacipran; 77% venlafaxine, as was the rate of MADRS remission (score ≤ 10 (week 8: 42.2% milnacipran; 42.5% venlafaxine; week 24: 52.2% milnacipran; 62.1% venlafaxine.

    Tonsillectomy has been performed by a number of techniques. This double blind randomized controlled study compares the technique of tissue coblation with bipolar dissection for the removal of tonsils in 10 adult patients with a history of chronic tonsillitis. A significant reduction in post-operative pain and more rapid healing of the tonsillar fossae were found in the side removed by tissue coblation. There were no episodes of primary or secondary haemorrhage on either side. This new technique for tonsil removal warrants further study.

    Full Text Available Background: Coblation tonsillectomy is a new surgical technique and demands further research to be proven as a suitable and standard method of tonsillectomy. This study compares coblation and traditional tonsillectomy techniques in view of their advantages and complications. Methods: In a prospective double-blind randomized controlled trial information on operation time, intraoperative blood loss, postoperative pain, time needed to regain the normal diet and activity and post-operative hemorrhage were gathered and compared between two groups containing 47 patients in each group. Results: We found statistically significant differences in operation time (p 0.5 was not significantly different between two groups. Conclusions: This study revealed a significantly less intraoperative or postoperative complications and morbidity in coblation tonsillectomy in comparison with traditional method. Coblation was associated with less pain and quick return to normal diet and daily activity. These findings addressed coblation tonsillectomy as an advanced method.

    Full Text Available Abstract Background Epidemiological studies suggest that smokeless tobacco in the form of Swedish snus has been used by many smokers in Scandinavia to quit smoking, but the efficacy of snus has so far not been evaluated in controlled clinical trials. Methods We conducted a randomized, double-blind, placebo-controlled, clinical trial aimed at assessing the efficacy of snus to help adult cigarette smokers in Serbia to substantially reduce, and, eventually, completely stop smoking. The study enrolled 319 healthy smokers aged 20-65 years at two occupational health centers in Belgrade, Serbia. Most of them (81% expressed an interest to quit rather than just reduce their smoking. Study products were used ad libitum throughout the 48-week study period. The main study objective during the first 24 weeks was smoking reduction. The primary end-point was defined as a biologically verified reduction of ≥ 50% in the average number of smoked cigarettes per day during week 21-24 compared to baseline. During week 25-48 participants were actively instructed to stop smoking completely. Outcome measures of biologically verified, complete smoking cessation included 1-week point prevalence rates at clinical visits after 12, 24, 36, and 48 weeks, as well as 4-, 12- and 24-week continued cessation rates at the week 36 and 48 visits. Results At the week 24 visit, the proportion of participants who achieved the protocol definition of a ≥ 50% smoking reduction was similar in the two treatment groups. However, the proportion that reported more extreme reductions (≥ 75% was statistically significantly higher in the snus group than in the placebo group (p Conclusions Swedish snus could promote smoking cessation among smokers in Serbia, that is, in a cultural setting without traditional use of oral, smokeless tobacco.

  10. Hydroxyurea: a radiation potentiator in carcinoma of the uterine cervix. A randomized double-blind study

    International Nuclear Information System (INIS)

    From June, 1972, to December, 1976, 40 patients with FIGO (International Federation of Gynaecology and Obstetrics) Stage IIB carcinoma of the uterine cervix were entered into a prospective, double-blind, randomized study to evaluate the possible radiation-potentiating properties (i.e., improved survival) of the S-phase cell cycle-specific inhibitor of DNA synthesis, hydroxyurea. All patients were documented to be without aortic lymph node metastasis by pretherapy staging para-aortic lymphadenectomy. All 40 patients were followed up for longer than 5 years (5.2 to 9.2 years) or until death. The double-blind code was not broken until all patients had been followed up for a minimum of 2 to 5 years. Leukopenia (white blood cell count less than 2,500 mm3) was significantly increased in the patients given hydroxyurea as compared to those given placebo (P less than 0.0001). There was no statistically significant difference relative to anemia, thrombocytopenia, radiation-induced skin reaction, and radiation-induced intestinal reaction between the patients given placebo or those given hydroxyurea. Life-table survival for the patients given hydroxyurea was 94% as compared to 53% for the patients given placebo (P . 0.006). Only one (5%) patient given hydroxyurea died of cervical cancer. Of the other patients who died in the group given hydroxyurea, all were confirmed by postmortem examination to have been without recurrent cervical cancer. In contrast, 45% (nine) of the patients given placebo died of cervical cancer

This randomized, placebo-controlled, double-blind study was designed to investigate the efficacy and tolerability of PSO for treatment of hair growth in male patients with mild to moderate androgenetic alopecia (AGA. 76 male patients with AGA received 400 mg of PSO per day or a placebo for 24 weeks. Change over time in scalp hair growth was evaluated by four outcomes: assessment of standardized clinical photographs by a blinded investigator; patient self-assessment scores; scalp hair thickness; and scalp hair counts. Reports of adverse events were collected throughout the study. After 24 weeks of treatment, self-rated improvement score and self-rated satisfaction scores in the PSO-treated group were higher than in the placebo group (P = 0.013, 0.003. The PSO-treated group had more hair after treatment than at baseline, compared to the placebo group (P<0.001. Mean hair count increases of 40% were observed in PSO-treated men at 24 weeks, whereas increases of 10% were observed in placebo-treated men (P<0.001. Adverse effects were not different in the two groups.

    Wound infusion with local anesthetics has been used for postoperative pain relief with variable results. This randomized, controlled, double-blind clinical trial examines the effect of ropivacaine infusion on pain after laparoscopic cholecystectomy. A total of 110 patients were randomly assigned to 2 groups. After induction of anesthesia a 75-mm catheter was inserted subcutaneously and connected to an elastomeric pump containing either 0.75% ropivacaine (ropivacaine group) or normal saline (control group) for 24 hours postoperatively. Before skin closure, each hole was infiltrated with 2 mL of 0.75% ropivacaine or normal saline according to randomization. Pain at rest, pain during cough, and analgesic consumption were recorded in the postanesthesia care unit and at 2, 4, 8, 24, and 48 hours postoperatively. Analgesic requirements and pain scores were recorded 1 and 3 months after surgery. The ropivacaine group reported less pain during cough (P=0.044) in the postanesthesia care unit (P=0.017) and 4 hours postoperatively (P=0.038). Ropivacaine wound infusion had no effect on late and chronic pain. PMID:26679680

Method: "nA randomized double blind study was conducted on a fixed dose of herbal vigRX at Roozbeh Psychiatry Hospital, Tehran University of Medical Sciences. The sample consisted of 85 married patients diagnosed withprimary PE according to Diagnostic and Statistical Manual of Mental Disorders. Each patient underwent diagnostic evaluation by one trained psychiatrist, using Structured Clinical Interview for DSM-IV-TR. Each patient was evaluated by researchers to exclude the organic sexual dysfunctions. The patients were randomly assigned in to two groups: group 1 consisting of 42 patients receiving placebo, and group 2 consisting of 43 patients receiving 540 mg herbal vigRX for a 4-week treatment course. The effects of the drug on the ejaculatory function in each group were assessed by the intravaginal ejaculation latency time (IELT, and the Chinese Index of Premature Ejaculation (CIPE before and at the end of the treatment course. Statistical analysis was performed using SPSS software (15th version.      Results: "nThe mean IELT increased 22.4 and 32.0 seconds in the placebo and the vigRX group respectively after the treatment course. The mean IELT differences between the two groups was not significant. The mean CIPE score increased 2.40 and 4.37 in the placebo and the vigRX group respectively .The mean CIPE score differences between the two groups was not significant.No side effect was reported by the subjects in neither groups during the treatment course. "nConclusion: Although the improvement in IELT and CIPE scores in the herbal vigRX group was more than the placebo group, this difference was not statistically significant. The increasing of IELT and CIPE score in the placebo group may be due to the placebo effects. Further studies with higher vigRX doses, greater sample size

    Full Text Available Introduction: There is some evidence that omega-3 fatty acids are associated with depression. The aim of this study was to compare the effects of eicosapentaenoic acid(EPA and placebo on mild to moderate depression. Methods: This double-blind randomized clinical trial was conducted on 54 outpatients with mild to moderate depression. Patients were randomly assigned to two groups: receiving EPA supplement or placebo. EPA and placebo groups received two identical capsules per day for 12 weeks. Each capsule contained 500 mg EPA or coconut oil. Hamilton Rating Scale for Depression(HRSD was used to determine the severity of depression at baseline, sixth and twelfth weeks after intervention. Results: Forty two patients(77.8% completed the 12-week intervention. A statistically significant difference was observed in mean scores of HRSD between EPA and placebo groups at the end of the study (P=0.001. Mean scores of HRSD decreased over time in both groups so that the analysis of variance for repeated measurements showed a statistically significant time effect(F=50.55, df=1.32, P<0.0001. Also, a statistically significant treatment effect of EPA compared to placebo was observed over time (treatment*time interaction, F=12.67, df=1.32, P=0.0001. Conclusion: The results of this study showed the efficacy of EPA in treatment of depression, so its use is recommended as an add-on to antidepressant medications in treatment of mild to moderate depression.

    In a randomized, double-blind, parallel clinical trial, the authors tested and compared flecainide and cibenzoline, a new antiarrhythmic drug, on atrial arrhythmias. Sixty-eight patients (36 men, 32 women, mean age 62.5 +/- 1.6 years) with documented symptomatic paroxysmal atrial arrhythmias (fibrillation in 56, flutter in 12) were recruited and received either cibenzoline 260 mg/day (n = 33) or flecainide 200 mg/day (n = 35). Patients were assessed with physical examination, resting ECG, 24-hour ambulatory ECG recording, two-dimensional echocardiography, and standard biologic titrations before the inclusion day, and 3 months and 6 months after the randomization day. Sixteen patients were withdrawn (7 were lost to follow-up, 7 had side effects, 2 had another medical event). Seventeen patients had documented recurrence of atrial arrhythmia (9 in the cibenzoline group, 8 in the flecainide group) during the study. The efficacy of cibenzoline and flecainide for preventing recurrence of atrial arrhythmias was not significantly different (62.5% versus 71.4%). Eleven patients complained of one or more side effects (cibenzoline, n = 6; flecainide, n = 5), justifying leaving the trial in 6 cases (cibenzoline, n = 3; flecainide, n = 3). Two ventricular proarrhythmic effects were observed. No atrial proarrhythmic effects were reported. The efficacy of cibenzoline and flecainide for preventing atrial arrhythmia is good and similar during a follow-up period of 6 months. In view of these results, cibenzoline may be administered first to prevent atrial arrhythmia. PMID:7657846

    Combination of non-nicotine pharmacotherapies has been underexamined for cigarette smoking cessation. A randomized, double-blind, parallel-group double-dummy study evaluated two medications, bupropion (BUP) and naltrexone (NTX), in treatment-seeking cigarette smokers (N = 121) over a 7-week treatment intervention with 6-month follow-up. Smokers were randomized to either BUP (300 mg/day) + placebo (PBO) or BUP (300 mg/day) + NTX (50 mg/day). The primary outcome was biochemically verified (saliva cotinine, carbon monoxide) 7-day, point-prevalence abstinence. BUP + NTX was associated with significantly higher point-prevalence abstinence rates after 7-weeks of treatment (BUP + NTX, 54.1%; BUP + PBO, 33.3%), P = 0.0210, but not at 6-month follow-up (BUP + NTX, 27.9%; BUP + PBO, 15.0%), P = 0.09. Continuous abstinence rates did not differ, P = 0.0740 (BUP + NTX, 26.2%; BUP + PBO, 13.3%). Those receiving BUP + NTX reported reduced nicotine withdrawal, P = 0.0364. The BUP + NTX combination was associated with elevated rates of some side effects, but with no significant difference in retention between the groups. PMID:27213949

    Full Text Available Objectives: To compare the anti platelet effects of locally manufactured clopidogrel with the anti platelet effect of clopidogrel manufactured by multinational pharmaceutical abroad. Methodology: A total of 118 subjects were enrolled, 18 to 65 years of age, who presented with suspected ischemic heart disease and were randomly assigned to receive either drug A (Pidogrel or drug B (Plavix in a double blind manner for 7 days. Platelet aggregation was measured in both the groups at baseline and at final visit. Results: Base line platelet aggregability in both drug groups was not significantly different (p=0.317 Mean reduction in platelet aggregation by drug-A was 8.47+/- 0.45 ohms (p<0.001 and mean reduction in platelet aggregation by drug-B was 8.62+/- 0.46 (p<0.001. The difference in platelet aggregability at day 7(follow up between the two groups was not statistically significant i.e., was the same. Conclusion: Locally manufactured clopidogrel is equally effective as that manufactured by the multinational company abroad giving us the added advantage of cost effectiveness

    Full Text Available Attention-Deficit/Hyperactivity Disorder is one of the most common mental disorders in childhood, and it continues to adulthood without proper treatment. Stimulants have been used in the treatment of Attention-Deficit/Hyperactivity Disorder (ADHD for many years, and the efficacy of methylphenidate in the treatment of adults with ADHD has been proven to be acceptable according to meta-analysis studies. However, there are some concerns about stimulants. Finding other effective medications for the treatment of adult ADHD seems necessary. We hypothesized bupropion could be effective in the treatment of adult ADHD because some theoretical and experimental evidence exists to support efficacy of this medication. Forty-two patients with a diagnosis of ADHD, according to the revised fourth edition of the Diagnostic and Statistical Manual of Mental Disorders, were randomized to receive 150 mg/day bupropion or placebo for a 6-week double-blind, placebo-controlled clinical trial. Each patient filled the Conners' Adult ADHD Rating Scales-Self-Report-Screening version (CAARS before starting to take medication and in weeks 3 and 6 of the study. The mean score of the two groups receiving bupropion or placebo decreased over the 6 weeks. There was a significant difference between the two groups in CAARS score after 6 weeks. Bupropion is more effective than placebo in the treatment of adults with ADHD. Bupropion can be an alternative medication for the treatment of Adults with ADHD as its clinical efficacy was proven by other studies.

    Full Text Available Abstract Background The Paracetamol (Acetaminophen In Stroke (PAIS study is a phase III multicenter, double blind, randomized, placebo-controlled clinical trial of high-dose acetaminophen in patients with acute stroke. The trial compares treatment with a daily dose of 6 g acetaminophen, started within 12 hours after the onset of symptoms, with matched placebo. The purpose of this study is to assess whether treatment with acetaminophen for 3 days will result in improved functional outcome through a modest reduction in body temperature and prevention of fever. The previously planned statistical analysis based on a dichotomization of the scores on the modified Rankin Scale (mRS may not make the most efficient use of the available baseline information. Therefore, the planned primary analysis of the PAIS study has been changed from fixed dichotomization of the mRS to a sliding dichotomy analysis. Methods Instead of taking a single definition of good outcome for all patients, the definition is tailored to each individual patient's baseline prognosis on entry into the trial. Conclusion The protocol change was initiated because of both advances in statistical approaches and to increase the efficiency of the trial by improving statistical power.

    Selective serotonin reuptake inhibitors (SSRIs) are known to induce delayed orgasm and ejaculation. However, different SSRIs may differentially delay ejaculation. A double-blind, fixed-dose study in healthy men with lifelong rapid ejaculation was performed to evaluate potential differences between clinically relevant doses of two selective serotonin reuptake inhibitors, paroxetine and citalopram, in their effects on ejaculation. Thirty men with an intravaginal ejaculation latency time (IELT) less than 1 minute were randomly assigned to receive paroxetine (20 mg/day) and citalopram (20 mg/day) for 5 weeks, after taking half the dosage in the first week. During the 1-month baseline and 6-week treatment period, IELTs were measured at home by using a stopwatch procedure. The trial was completed by 23 men. Analysis of variance revealed a between-group difference in the evolution of IELT delay over time (p = 0.0004); the IELT after paroxetine and citalopram gradually increased from 18 and 21 seconds to approximately 170 and 44 seconds, respectively. Paroxetine 20 mg/day exerted a strong delay (8.9-fold increase), whereas citalopram 20 mg/day mildly delayed ejaculation (1.8-fold increase). These results indicate that paroxetine leads to a significant delay in orgasm and ejaculation, whereas citalopram seems to have less of an effect on it. PMID:11763001

    Full Text Available Background: Irritable bowel syndrome (IBS is gastrointestinal functional disorder which is multifactorial with unknown etiology. There are several modalities for treatment of it. Acupuncture is increasingly used in numerous diseases, also in gastrointestinal disorders like IBS. The purpose of the study was to assess the effects of catgut embedding acupuncture in improving of IBS. Materials and Methods: A randomized double blind sham control clinical trial was designed. A total of 60 IBS patients assigned to three separated groups. The first group received clofac as drug only group (DO. The second one received catgut embedding acupuncture in special point (AP and the last group received sham acupuncture (SA. Symptoms, pain, depression and anxiety assessed before and after two weeks at the end of study. Results: There was statistically significant difference between AP and SA and DO in constipation and bloating. Differences that were statistically significant favored acupuncture on pain (F = 6.409, P = 0.003, and depression (F = 6.735, P = 0.002 as the other outcomes. The average (standard deviation (SD of weight loss was 2 kg (0.88 in acupuncture group. Conclusion: Our finding showed a significant positive associated between acupuncture and IBS. Catgut embedding acupuncture is a new method which can eliminated IBS symptoms and can use as alternative therapeutic method for improvement of IBS.

These results indicate that paroxetine leads to a significant delay in orgasm and ejaculation, whereas citalopram seems to have less of an effect on it.

  18. Randomized double-blind trial of prednisone versus radiotherapy in Graves' ophthalmopathy

    International Nuclear Information System (INIS)

    Corticosteriods are usually given for management of Graves' ophthalmopathy, but they have many and serious side-effects. By comparison, retrobulbar irradiation is well tolerated, although its efficacy has been evaluated only in uncontrolled studies. Therefore, the authors did a double-blind randomized trial, in which 28 patients with moderately severe Graves' ophthalmopathy were treated with a 3-month course of oral prednisone and sham irradiation, and 28 received retrobulbar irradiation (20 Gy) and placebo capsules. Therapeutic outcome, assessed twenty-four weeks after the start of treatment, was determined by the change in the highest NOSPECS class. A successful outcome was observed in 14 prednisone-treated and in 13 irradiated patients. Responders to treatment (but not nonresponders) in both groups showed improvements in total and subjective eye score and a decrease in eye-muscle volume. Response to either treatment was due largely to changes in soft-tissue involvement and eye-muscle motility. Radiotherapy and oral prednisone appear to be equally effective as initial treatment in patients with moderately severe Graves' ophthalmopathy. In view of its better tolerability, radiotherapy should be considered the treatment of first choice

    Fragile X syndrome (FXS), the most common cause of inherited intellectual disability and autistic spectrum disorder, is typically caused by transcriptional silencing of the X-linked FMR1 gene. Work in animal models has described altered synaptic plasticity, a result of the up-regulation of metabotropic glutamate receptor 5 (mGluR5)-mediated signaling, as a putative downstream effect. Post hoc analysis of a randomized, placebo-controlled, crossover phase 2 trial suggested that the selective mGluR5 antagonist mavoglurant improved behavioral symptoms in FXS patients with completely methylated FMR1 genes. We present the results of two phase 2b, multicenter, randomized, double-blind, placebo-controlled, parallel-group studies of mavoglurant in FXS, designed to confirm this result in adults (n = 175, aged 18 to 45 years) and adolescents (n = 139, aged 12 to 17 years). In both trials, participants were stratified by methylation status and randomized to receive mavoglurant (25, 50, or 100 mg twice daily) or placebo over 12 weeks. Neither of the studies achieved the primary efficacy end point of improvement on behavioral symptoms measured by the Aberrant Behavior Checklist-Community Edition using the FXS-specific algorithm (ABC-C(FX)) after 12 weeks of treatment with mavoglurant. The safety and tolerability profile of mavoglurant was as previously described, with few adverse events. Therefore, under the conditions of our study, we could not confirm the mGluR theory of FXS nor the ability of the methylation state of the FMR1 promoter to predict mavoglurant efficacy. Preclinical results suggest that future clinical trials might profitably explore initiating treatment in a younger population with longer treatment duration and longer placebo run-ins and identifying new markers to better assess behavioral and cognitive benefits.

    Aging can result in major changes in the composition and metabolic activities of bacterial populations in the gastrointestinal system and result in impaired function of the immune system. We assessed the efficacy of prebiotic Darmocare Pre® (Bonusan Besloten Vennootschap (BV), Numansdorp, The Netherlands) to evaluate whether the regular intake of this product can improve frailty criteria, functional status and response of the immune system in elderly people affected by the frailty syndrome. The study was a placebo-controlled, randomized, double blind design in sixty older participants aged 65 and over. The prebiotic product was composed of a mixture of inulin plus fructooligosaccharides and was compared with placebo (maltodextrin). Participants were randomized to a parallel group intervention of 13 weeks’ duration with a daily intake of Darmocare Pre® or placebo. Either prebiotic or placebo were administered after breakfast (between 9–10 a.m.) dissolved in a glass of water carefully stirred just before drinking. The primary outcome was to study the effect on frailty syndrome. The secondary outcomes were effect on functional and cognitive behavior and sleep quality. Moreover, we evaluated whether prebiotic administration alters blood parameters (haemogram and biochemical analysis). The overall rate of frailty was not significantly modified by Darmocare Pre® administration. Nevertheless, prebiotic administration compared with placebo significantly improved two frailty criteria, e.g., exhaustion and handgrip strength (p < 0.01 and p < 0.05, respectively). No significant effects were observed in functional and cognitive behavior or sleep quality. The use of novel therapeutic approaches influencing the gut microbiota–muscle–brain axis could be considered for treatment of the frailty syndrome. PMID:27314331

    Full Text Available Background: We sought to evaluate the efficacy and safety of the different trade forms of streptokinase available in our country, namely Heberkinasa (Heberbiotec, Havana, Cuba and Streptase (Aventis Behring GmbH, Marburg, Germany. Methods: We conducted a double-blind randomized clinical trial to compare the two streptokinase formulations, i.e. Heberkinasa (HBK or Streptase (STP, in patients with acute myocardial infarction who needed thrombolysis. Thrombolysis success was evaluated angiographically and/or clinically. Clinical follow-up was done 30 days after thrombolysis. Results: We randomly allocated 221 patients with a mean age of 56.9±10.8 years (males: 88.2% to HBK (n=119 and STP (n=102 groups. Baseline clinical and demographic characteristics were similar between the two groups, and the two groups were not significantly different in terms of door-to-needle and pain-to-needle intervals. The rate of complications was not significantly different between the groups (44.1% [HBK] vs. 42% [STP]. Angiography was done for 158 (71.5 % patients in the first 24 hours (9% and in the first 72 hours (38.8% after thrombolysis. Lesion morphology and lesion/patient ratio were not significantly different between the two groups (1.87[HBK] vs. 1.67[STP]. The two groups were similar with respect to angiographic patency rate (67.5% [HBK] vs. 67.6% [STP]. The study groups were also similar as regards clinical outcome and complications of both streptokinase formulations. Conclusion: The present study demonstrated that Heberkinasa is as effective and as safe as a standard streptokinase, namely Streptase, in a clinical setting.

    This randomized double blind study was conducted prospectively to determine whether coblation tonsillectomy fared better than the conventional dissection method in terms of postoperative pain, bleeding, and rapidity of healing in adult Indian patients undergoing tonsillectomy. Sixty adult patients undergoing tonsillectomy for benign indications were randomized to have one tonsil removed by subcapsular radiofrequency ablation method and the other by conventional dissection method. The operative time and blood loss was noted for each side. Patients were evaluated at 6, 12, 24, 48, 72 h and then on 7th and 20th postoperative day for postoperative pain (by visual analog scale), bleeding, and tonsillar fossa healing. Statistical comparison was done using appropriate tests. The two groups were demographically matched. It took longer to perform the coblation procedure (15 vs 11 min) (P > 0.05). The operative blood loss on the radiofrequency side was 11 ml, vs 34 ml on the conventional side (P = 0.009). 77% patients said that the coblation side was less painful for the overall 20-day recovery period. There were significant differences seen at 6, 12, 24, 48, and 72 h in terms of postoperative pain scores. Beyond that, the pain was consistently less on the coblation side, but the difference was not significant. There was no case of reactionary or secondary hemorrhage in either arm. The healing took longer on the radiofrequency side. Coblation tonsillectomy is an easy to learn technique with significantly reduced operative blood loss and postoperative pain. Longer operative times maybe further reduced with experience.

    Background: We aimed to evaluate the effects of Pimpinella anisum (anise) from Apiaceae family on relieving the symptoms of postprandial distress syndrome (PDS) in this double-blind randomized clinical trial. Materials and Methods: Totally, 107 patients attending the gastroenterology clinic, aged 18-65 years, diagnosed with PDS according to ROME III criteria and signed a written consent form were enrolled. They were randomized to receive either anise or placebo, blindly, for 4 weeks. Anise group included 47 patients and received anise powders, 3 g after each meal (3 times/day). Control group involved 60 patients and received placebo powders (corn starch), 3 gafter each meal (3 times/day). The severity of Functional dyspepsia (FD) symptoms was assessed by FD severity scale. Assessments were done at baseline and by the end of weeks 2, 4 and 12. Mean scores of severity of FD symptoms and the frequency distribution of patients across the study period were compared. Results: The age, sex, body mass index, smoking history, and coffee drinking pattern of the intervention and control groups were not significantly different. Mean (standard deviation) total scores of FD severity scale before intervention in the anise and control groups were 10.6 (4.1) and 10.96 (4.1), respectively (P = 0.6). They were 7.04 (4.1) and 12.30 (4.3) by week 2, respectively (P = 0.0001), 2.44 (4.2) and 13.05 (5.2) by week 4, respectively (P = 0.0001), and 1.08 (3.8) and 13.30 (6.2) by week 12, respectively (P = 0.0001). Conclusion: This study showed the effectiveness of anise in relieving the symptoms of postpartum depression. The findings were consistent across the study period at weeks 2, 4 and 12. PMID:25767516

    Fontan surgery is a widely used palliative procedure that significantly improves the survival period of patients with complex congenital heart disease (CHD). However, it does not decrease postoperative complication rate. Previous studies suggested that elevated mean pulmonary artery pressure (mPAP) and vascular resistance lead to decreased exercise tolerance and myocardial dysfunction. Therapy with endothelial receptor antagonists (Bosentan) has been demonstrated to improve the patients' prognosis. A double-blind, randomized controlled trial was performed to explore the efficacy of Bosentan in treating patients who underwent the Fontan procedure. Eligible participants were randomly divided into Bosentan group and control group. Liver function was tested at a local hospital and the results were reported to the phone inspector every month. If the results suggested abnormal liver function, treatment would be adjusted or terminated. All the participants finished the follow-up study, with no patients lost to follow-up. Unblinding after 2-year follow-up, no mortality was observed in either group. However, secondary end-points were found to be significantly different in the comparable groups. The cardiac function and 6-min walking distance in the Bosentan group were significantly superior to those in the control group (P=0.018 and P=0.027). Bosentan could improve New York Heart Association (NYHA) functional status and improve the results of the 6-min walking test (6MWT) in Fontan patients post-surgery, and no other benefits were observed. Furthermore, a primary meta-analysis study systematically reviewed all the similar clinical trails worldwide and concluded an overall NYHA class improvement in Fontan patients who received Bosentan treatments.

    Full Text Available "nAs the most common male sexual disorder premature ejaculation (PE, also referred to as early ejaculation (EE or rapid ejaculation (RE, affects 30%-40% of sexually active men. Despite the limited number of available studies comparing the efficacy of selective serotonin re-uptake inhibitors (SSRI they have been thought to have beneficial effects for the treatment of patients with PE. In the present study, we assessed the efficacy of on-demand use of citalopram, in the treatment of premature ejaculation. A randomized double blind study of fixed dose on-demand use of citalopram was performed in Roozbeh Psychiatry Hospital, Tehran University of Medical Sciences. The sample was consisted of 80 married patients diagnosed with PE according to Diagnostic and Statistical Manual of Mental Disorders. The patients were randomly assigned to two groups: group 1 consisting of 42 patients received 20mg citalopram, and group 2 consisting of 38 patients received placebo four hours before intercourse for a 4-week treatment course. The effects of drug on the ejaculatory function in each group were assessed by the intravaginal ejaculation latency time (IELT, and the Chinese Index of Premature Ejaculation (CIPE before and at the end of treatment course. The mean IELT increased from 66.78±36.94 to 80.85±43.05 seconds in group 1 and from 63.44±33.16 to 65.71±34.26 seconds in group 2 (P = 0.000. Mean CIPE score increased 1.14±1.04 and 0.52±0.50 in group 1 and 2 respectively (P = 0.002. The patients treated with on demand citalopram showed significantly greater improvement in IELT and CIPE score compared to the patients receiving placebo. It seems that citalopram may be an effective treatment of premature ejaculation with on-demand usage. However further studies are warranted.

    2001-09-01

    Full Text Available Introduction. Extradural anesthesia is a successfull procedure in many operations.This is also a suitable and elective anesthetic procedure in many operations have particular hemodynamic conditions. Hence the onset time on this of anesthesia is slow and the degree of sensory and motor block is relatively variable in many cases, this procedure is not accepted by anesthesiologists and surgeons. So, inspite of its priority in many cases, it is less used. Thegoal of this study is to achieve a practical and effective solution to shorten the onset of analgesia and increasing analgesic duration which studies adding ketamin to bupivacain in extradural anesthesia. Methods. This study is a double blinded randomized clinical trial. Forty adult patients in class 1 and 2 of ASA who have been candidate for elective lower limb or lower abdominal surgery in Al-zahra and Kashani medical center in 1998 were selected. Without receiving any premedications, all of the patients received 500 CC ringer lactated solution before onset of anesthesia and they were divided into 2 groups. Group 1 received 20 cc of 0.5 percent bupivacain+0.5cc of 0.9 percent normal saline. Group 2 (interventional received 20 cc of 0.5 percent bupivacain + 0.5 cc of Ketamin (25mg. The onset of sensory block and the duration of sensory and motor block were measured and compared in both groups. Results. The onset of sensory block in interventional group was shorter than in controlled group. The duration of sensory block in interventional group was longer than in controlled group. The duration of the motor block was longer in controlled group than interventional group (P < 0.05. Discussion. Adding ketamin to bupivacain results in earlier onset and longer duration of analgesia in extradural anesthesia. This effect may be due to the inhibitory effect of the ketamin on posterior nerve root activity in spinal cord which can be an effective mechanism of ketamin in making analgesia.

Methods: This double-blind randomized clinical trial was carried out at Eusebio Hernandez Hospital (Havana, Cuba. A total of 2,418 women who requested emergency contraception after unprotected coitus received either 5 mg or 10 mg mifepristone. The variables for assessing efficacy were the pregnancies that occurred and the fraction of pregnancies that were prevented. Other variables assessed were the side effects of mifepristone, vaginal bleeding, and changes in the date of the following menstruation. Results: There were 15/1,206 (1.2% and 9/1,212 (0.7% pregnancies in the 5 mg and 10 mg group, respectively (P=0.107. There were 88% and 93% prevented pregnancies in the 5 mg and 10 mg group, respectively. The side effect profiles were similar in both groups. Delayed menstruation ≥7 days was experienced by 4.9% and 11.0% of subjects in the 5 mg and 10 mg group, respectively (P=0.001. There was a significant high failure rate for women weighing >75 kg in the 5 mg group. Conclusion: It would be advisable to use the 10 mg dose of mifepristone for emergency contraception as there was a trend suggesting that the failure rate of the larger dose was lower.

    Some open-label studies suggest that risperidone can be useful in the treatment of certain target symptoms in children with autism. We aimed to study whether the use of risperidone in comparison with placebo improved functioning in children with autism with regard to behavior (aggressiveness, hyperactivity, irritability), social and emotional responsiveness, and communication skills. We conducted a randomized, double-blind, placebo-controlled trial with 40 consecutive children with autism, whose ages ranged from 2 to 9 years, who were receiving either risperidone or placebo given orally at a dose of 1 mg/day for 6 months. Autism symptoms were monitored periodically. The outcome variables were total scores on the Childhood Autism Rating Scale (CARS) and the Children's Global Assessment Scale (CGAS) after 6 months. Of the 40 children enrolled, 39 completed the trial over a period of 18 months; 19 received risperidone, and 20 received placebo. In the risperidone group, 12 of 19 children showed improvement in the total Childhood Autism Rating Scale score and 17 of 19 children in the Children's Global Assessment Scale score compared with 0 of 20 children for the Childhood Autism Rating Scale score and 2 of 20 children for the Children's Global Assessment Scale score in the placebo group (P social responsiveness and nonverbal communication and reduced the symptoms of hyperactivity and aggression. Risperidone was associated with increased appetite and a mild weight gain, mild sedation in 20%, and transient dyskinesias in three children. Risperidone improved global functioning and social responsiveness while reducing hyperactivity and aggression in children with autism and was well tolerated. PMID:16948927

    Aim: To evaluate the treatment of male infertility with a strong natural antioxidant, in addition to conventional treatment.Methods: Using a double blind, randomized trial design, 30 men with infertility of ≥12 months and female partners with no demonstrable cause of infertility received conventional treatment according to the guidelines of the World Health Organization (WHO), and either a strong antioxidant Astaxanthin 16 mg/day (AstaCarox(R), AstaReal AB,Gustavsberg, Sweden) or placebo for 3 months. The effects of treatment on semen parameters, reactive oxygen species (ROS), zona-free hamster oocyte test, serum hormones including testosterone, luteinizing hormone (LH),follicle stimulating hormone (FSH) and Inhibin B, and spontaneous or intrauterine insemination (IUI)-induced pregnancies were evaluated. Results: ROS and Inhibin B decreased significantly and sperm linear velocity increased in the Astaxanthin group (n = 11), but not in the placebo group (n = 19). The results of the zona-free hamster oocyte test tended to improve in the Astaxanthin group in contrast with the placebo group, though not reaching statistical significance.The total and per cycle pregnancy rates among the placebo cases (10.5 % and 3.6 %) were lower compared with 54.5 % and 23.1% respectively in the Astaxanthin group (P = 0.028; P = 0.036). Conclusion: Although the present study suggests a positive effect of Astaxanthin on sperm parameters and fertility, the results need to be confirmed in a larger trial before recommending Astaxanthin for the complementary treatment of infertile men.

    Periampullary neoplasms are rapidly progressive tumors with a poor prognosis and high morbidity and mortality rates, which have a negative influence on patient outcomes. Some probiotics and prebiotics have the ability to protect the intestinal barrier and prevent bacterial translocation, infection, and postoperative complications. We evaluated the use of synbiotics in a prospective, double-blind study of patients undergoing surgery for periampullary neoplasms (PNs) and assessed the effect of these agents on nutritional status, postoperative complications, antibiotic use, length of hospital stay, and mortality. Patients were randomized to receive probiotics and prebiotics-synbiotics--group S [Lactobacillus acidophilus 10, 1 × 10(9)CFU, Lactobacillus rhamnosus HS 111, 1 × 10(9) CFU, Lactobacillus casei 10, 1 × 10(9) CFU, Bifidobacterium bifidum, 1 × 10(9)CFU, and fructooligosaccharides (FOS) 100 mg]--or placebo-controls--group C, twice daily, for a total of 14 days. Risk, clinical status, and postoperative complication rates were assessed. Twenty-three patients were allocated to each group. The incidence of postoperative infection was significantly lower in group S (6 of 23 patients, 26.1%) than in group C (16 of 23 patients, 69.6%) (P = 0.00). Duration of antibiotic therapy was also shorter in group S (mean = 9 days vs. 15 days in group C; P = 0.01). Noninfectious complications were less common in group S (6 of 23 vs. 14 of 23 patients in group C; P = 0.03). Mean length of hospital stay was 12 ± 5 days in group S vs. 23 ± 14 days in group C (P = 0.00). No deaths occurred in group S, whereas 6 deaths occurred in group C (P = 0.02). Perioperative administration of synbiotics reduces postoperative mortality and complication rates in patients undergoing surgery for PNs. PMID:25803626

    Full Text Available Background: One of the most common complaints after coronary artery bypass graft (CABG is post-operative pain. Gabapentin is an anticonvulsant and antineuralgic agent. Objective: To evaluate the analgesic effect of preemptive gabapentin on post-operative pain and morphine consumption after cardiac surgery. Methods: A double-blind randomized clinical trial was conducted on 60 male candidates for CABG. The patients were divided into two groups—the gabapentin (n=30 and the control group (n=30. The test group received 800 mg gabapentin orally two hours before the surgery followed by 400 mg of the drug two hours post-extubation. The control group received placebo instead. Then severity of pain was recorded according to an 11-point visual analog pain scale. The amount of morphine consumed, its side effects and hemodynamic changes were also recorded during and at 2, 6, 12, 18 and 24 hours after extubation. Results: The mean±SD cumulative morphine consumption at the first 24 hours after extubation in gabapentin group was 0.9±1.5 mg while it was 1.5±4 mg for the control group. Therefore, gabapentin group consumed 38% less than the control group (P=0.01. The pain scores during rest and coughing at 2, 6, and 12 hours after extubation were also significantly lower in the gabapentin group compared with the control group (P=0.02. The mean±SD mechanical ventilation time was 5.4±1.7 hours for gabapentin group and 1.6±4.4 hours for the control group (P=0.035. The other variables including hemodynamic changes (HR, SBP and DBP, and incidence of nausea, vomiting and respiratory depression showed no significant difference between the studied groups within 24 hours after extubation. Conclusion: Oral pre-medication with gabapentin before CABG significantly reduces post-operative pain and morphine consumption in adult cardiac surgery.

    Objective Mucoactive drugs should increase the ability to expectorate sputum and, ideally, have anti-inflammatory properties. The aim of the study was to evaluate the mucolytic activity of Tyloxapol compared to saline (0.9%) in COPD. Design A randomized, placebo-controlled, double-blinded crossover, clinical trial was carried out. Patients were randomly assigned to either inhale 5 ml Tyloxapol 1% or saline 0.9% solution three times daily for 3 weeks and vice versa for another 3 weeks. 28 patients (18 male, 10 female, 47 to 73 years old, median age 63.50) were screened, 21 were treated and 19 patients completed the study per protocol. Results A comparison of the two treatment phases showed that the primary endpoint sputum weight was statistically significant higher when patients inhaled Tyloxapol (mean 4.03 g, 95% CI: 2.34–5.73 g at week 3) compared to saline (mean 2.63 g, 95% CI: 1.73–3.53 g at week 3). The p-value at three weeks of treatment was 0.041 between treatment arms. Sputum cells decreased during the Tyloxapol treatment after 3 weeks, indicating that Tyloxapol might have some anti-neutrophilic properties. Lung function parameters (FVC, FEV1, RV, and RV/TLC) remained stable during the study, and no treatment effect was shown. Interestingly, there was a mean increase in all inflammatory cytokines (IL-1β, IL-6, and IL-8) during the saline treatment from day 1 to week 3, whereas during the Tyloxapol treatment, all cytokines decreased. Due to the small sample size and the large individual variation in sputum cytokines, these differences were not significant. However, analyses confirmed that Tyloxapol has significant anti-inflammatory properties in vitro. Despite the high number of inhalations (more than 1000), only 27 adverse events (20 during the Tyloxapol and seven during saline) were recorded. Eleven patients experienced AEs under Tyloxapol and six under saline treatment, which indicates that inhalation of saline or Tyloxapol is a very safe procedure

    No drug to treat vascular dementia (VaD) has yet been approved by the American or European authorities, leaving a large population of patients without effective therapy. Cerebrolysin has a long record of safety and might be efficacious in this condition. We conducted a large, multicenter, double-blind, placebo-controlled study in 242 patients meeting the criteria for VaD. The primary endpoint was the combined outcome of cognition (based on Alzheimer's Disease Assessment Scale Cognitive Subpart, Extended Version [ADAS-cog+] score) and overall clinical functioning (based on Clinician's Interview-Based Impression of Change plus Caregiver Input [CIBIC+] score) assessed after 24 weeks of treatment. Intravenous Cerebrolysin 20 mL was administered once daily over the course of 2 treatment cycles as add-on therapy to basic treatment with acetylsalicylic acid. The addition of Cerebrolysin was associated with significant improvement in both primary parameters. At week 24, ADAS-cog+ score improved by 10.6 points in the Cerebrolysin group, compared with 4.4 points in the placebo group (least squares mean difference, -6.17; P Cerebrolysin group (ADAS-cog+ improvement of ≥4 points from baseline, 82.1% vs 52.2%; CIBIC+ score of Cerebrolysin, the odds ratio for achieving a favorable CIBIC+ response was 5.08 (P Cerebrolysin significantly improved clinical outcome, and that the benefits persisted for at least 24 weeks.

    2000-09-01

    AIM: To evaluate the effectiveness of paracetamol as a prophylactic analgesic for hysterosalpingography (HSG). DESIGN: A prospective double blind randomized controlled trial comparing one 1 g of paracetamol (SmithKline Beecham, Brentford, U.K.) to placebo taken 30 min before HSG. One hundred consecutive out-patients were studied prospectively. The analgesic effectiveness during the procedure and at 24 h and 1 week post procedure was analysed by a postal pain score questionnaire. Additional data on the ethnicity of the patient, sex and level of experience of the radiologist performing the hysterosalpingogram, the parity of the patient, the ease of the procedure, and whether pathology was identified were also recorded. RESULTS: Eighty-eight patients (88%) replied, 39 (44%) received paracetamol and 49 placebo (56%). During the procedure 3/39 (7%) of women in the paracetamol group were pain-free compared to 9/49 (18%) in the placebo group, which was not significant (P = 0.11). At 24 h, 15/39 (38%) of women in the paracetamol group were pain-free compared to 20/49 (41%) in the placebo group, which was not significant (P = 0.82). At 1 week, 27/39 (69%) of women in the paracetamol group were pain-free compared to 29/49 (59%) in the placebo group, which was not significant (P = 0.33). No significant difference in mean pain scores was determined during the procedure (P 0.91), or at 24 h post procedure (P = 0.94). Similarly, no difference in mean pain scores was identified with regard to the ethnicity of the patient, the sex of the radiologist performing the procedure, the level of experience of the radiologist performing the procedure, or whether pathology was present or not. Difficult cannulations were associated with higher mean pain scores, however, there was no difference in mean pain scores between the paracetamol or placebo groups for both easy and difficult cannulations. CONCLUSION: Paracetamol is not effective as a prophylactic analgesic for HSG. If a prophylactic

We used behavioral measures and functional magnetic resonance imaging to investigate the response to experimental thermal stimuli with APAP or placebo administration. Region-of-interest analysis revealed that activity in response to noxious stimulation diminished with APAP compared to placebo in prefrontal cortices, insula, thalami, anterior cingulate cortex, and periaqueductal gray matter.Conclusion: These findings suggest an inhibitory effect of APAP on spinothalamic tracts leading to a decreased activation of higher structures, and a top-down influence on descending inhibition. Further binding and connectivity studies are needed to evaluate how APAP modulates pain, especially in the context of repeated

  1. Sucralfate for radiation mucositis: results of a double-blind randomized trial

    International Nuclear Information System (INIS)

    Purpose: To determine if addition of the ulcer-coating polysaccharide sucralfate could improve symptomatic relief of radiation mucositis over a popular combination of antacid, diphenhydramine, and viscous lidocaine alone. Methods and Materials: A double-blind study was conducted in which nurses and pharmacists coded patient groups and distributed medication in a manner blinded to both the patients and physicians. Eligible patients receiving radiation to the head and neck and/or chest sites that included the esophagus were randomized to a standard combination of antacid, diphenhydramine, and viscous lidocaine vs. the same solution plus sucralfate. Eligible patients were those receiving >40 Gy at 1.8 Gy/fraction, one fraction/day, five fractions/week. Participating patients were stratified between chest, small field head and neck, and large field head and neck. The observations and smears for Candidiasis screening. Medication was prescribed when the patient became symptomatic and concomitant use of other locally effective nonstudy agents was not allowed. The ability to eat various consistency of foods was graded 0-5, with 5 indicating no compromise of ability to ingest a food compared to baseline. Statistical analysis included mean + SD for food and soreness scores, paired t-test, and two-way analyses of variance to evaluate effects of site and treatment group on the changes in scores. Results: Over 2 years, 111 patients were entered. Because some withdrew and others did not require medication, results are presented for evaluable patients in each category. Mild adverse effects from the medication solution (usually mouth discomfort) were reported by <10% of patients in each treatment group among 106 patients evaluable for toxicity. There was a comparable incidence of mild-moderate mucositis for the two treatment groups. Severe mucositis was noted in two patients of the standard medication group and none among patients receiving sucralfate. The groups were comparable

    Background. Daily preexposure prophylaxis (PrEP) with oral emtricitabine and tenofovir disoproxil fumarate (FTC/TDF) decreases the risk of human immunodeficiency virus (HIV) acquisition. Initiation of TDF decreases bone mineral density (BMD) in HIV-infected people. We report the effect of FTC/TDF on BMD in HIV-seronegative men who have sex with men and in transgender women. Methods. Dual-energy X-ray absorptiometry was performed at baseline and 24-week intervals in a substudy of iPrEx, a randomized, double-blind, placebo-controlled trial of FTC/TDF PrEP. Plasma and intracellular tenofovir concentrations were measured in participants randomized to FTC/TDF. Results. In 498 participants (247 FTC/TDF, 251 placebo), BMD in those randomized to FTC/TDF decreased modestly but statistically significantly by 24 weeks in the spine (net difference, −0.91% [95% confidence interval {CI}, −1.44% to −.38%]; P = .001) and hip (−0.61% [95% CI, −.96% to −.27%], P = .001). Changes within each subsequent 24-week interval were not statistically significant. Changes in BMD by week 24 correlated inversely with intracellular tenofovir diphosphate (TFV-DP), which was detected in 53% of those randomized to FTC/TDF. Net BMD loss by week 24 in participants with TFV-DP levels indicative of consistent dosing averaged −1.42% ± 29% and −0.85% ± 19% in the spine and hip, respectively (P < .001 vs placebo). Spine BMD tended to rebound following discontinuation of FTC/TDF. There were no differences in fractures (P = .62) or incidence of low BMD. Conclusions. In HIV-uninfected persons, FTC/TDF PrEP was associated with small but statistically significant decreases in BMD by week 24 that inversely correlated with TFV-DP, with more stable BMD thereafter.

    Purpose: To determine if addition of the ulcer-coating polysaccharide sucralfate could improve symptomatic relief of radiation mucositis over a popular combination of Maalox, diphenhyrdramine and viscous lidocaine alone. Methods: A double-blind study was conducted in which nurses/pharmacists coded patient groups and distributed medication in a manner blinded to both the patients and physicians. Eligible patients receiving radiation to the head and neck and/or chest sites that included the esophagus were randomized to a standard combination of Maalox, diphenhydramime and viscous lidocaine verses the same solution plus sucralfate. Eligible patients were those receiving > 40 Gy at 1.8 Gy/fraction, 1 fraction/day, 5 fractions/week. Participating patients were stratified between chest, small field head and neck, and large field head and neck. Baseline information regarding use of tobacco, alcohol, and food intake was obtained prior to symptomatic mucositis. This was compared with similar information obtained weekly once symptoms occurred. The patients subjected evaluation of throat soreness and relief with medication was elicited as well as physician observations and smears for Candidiasis screening. Medication was prescribed when the patient became symptomatic and concomitant use of other locally effective non-study agents was not allowed. Subjective soreness was graded on a scale of 0-20 with 0 indicating no soreness and 20 designating severe soreness that compromised ability to swallow secretions. The ability to eat various consistency of foods was graded 0-5 with 5 indicating no compromise of ability to ingest a food compared to baseline. Statistical analysis included mean + S.D. for food and soreness scores, paired t-test and two-way analyses of variance to evaluate effects of site and treatment group on the changes in scores. Results: Over 2 years, 110 patients were entered. Since some withdrew and others did not require medication, results are presented for

    A four-week, double-blind, randomized, placebo-controlled trial was conducted to assay the effectiveness of Ajwain 10 % (Trachyspermum ammi Sprague) topical cream on neuropathic pain. Intervention encompassed Ajwain 10 % and placebo creams. Ninety-two patients who specifically mentioned daily and nocturnal burning feet were randomly assigned to receive one of those interventions. Presence and decline in patients' numbness, tingling and allodynia were also evaluated. Major outcome measure was alteration in feet burning intensity (final week versus baseline week) regarding to a visual analog scale on a 0-10 cm scale (0 being "no pain", 10 being "worst pain"). Significant reduction in feet burning scores as well as numbness, tingling and allodynia were found in Ajwain group compared to placebo. This trial examining a cream of Ajwain essential oil versus placebo revealed the significance difference between two groups. This medicament can be a good candidate for the alleviation of feet burning, a neuropathic complication.

    This double-blind, randomized controlled study was conducted with the aim to investigate the effect of magnetic field therapy applied to the hip region on clinical and functional status in ankylosing spondylitis (AS) patients. Patients with AS (n = 66) who were diagnosed according to modified New York criteria were enrolled in this study. Patients were randomly divided in two groups. Participants were randomly assigned to receive magnetic field therapy (2 Hz) (n = 35), or placebo magnetic field therapy (n = 31) each hip region for 20 min. Patients in each group were given heat pack and short-wave treatments applied to bilateral hip regions. Both groups had articular range of motion and stretching exercises and strengthening exercises for surrounding muscles for the hip region as well as breathing and postural exercises by the same physical therapist. These treatment protocols were continued for a total of 15 sessions (1 session per day), and patients were examined by the same physician at months 1, 3 and 6. Visual analogue scale (VAS) pain, VAS fatigue, Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index (BASFI), Bath Ankylosing Spondylitis Metrologic Index (BASMI), DFI, Harris hip assessment index and Ankylosing Spondylitis Quality of Life scale (ASQOL) were obtained at the beginning of therapy and at month 1, month 3 and month 6 for each patient. There were no significant differences between groups in the VAS pain, VAS fatigue, morning stiffness, BASDAI, BASFI, BASMI, DFI, Harris hip assessment index and ASQoL at baseline, month 1, month 3 or month 6 (p > 0.05). Further randomized, double-blind controlled studies are needed in order to establish the evidence level for the efficacy of modalities with known analgesic and anti-inflammatory action such as magnetotherapy, particularly in rheumatic disorders associated with chronic pain.

    Full Text Available Objective: This study was undertaken to explore the efficacy and safety of Citrus sudachi peel for metabolic risk factors in obese male and female adults. Background: Citrus sudachi Hort. ex Shirai (Rutaceae, called “sudachi”, is a small, round, green citrus fruit that is mainly cultivated in Tokushima Prefecture in Japan. Our group reported that Citrus sudachi peel powder improved glucose tolerance and dyslipidemia in Zucher-fatty rats and reduced hyperglycemia and hypertriglyceridemia in GK diabetic rats. Materials and Methods: We conducted a randomized, double-blind, placebo-controlled trial in 40 participants with abdominal obesity and metabolic risk factors including hypertension, impaired glucose tolerance and elevated triglyceride levels. Participants were randomized to receive either tablets that contained 1.3 g dried Citrus sudachi peel powder or placebo tablets for 12 weeks. The sudachi peel group included 14 males and 5 females with a mean age of 54.5 years, and the placebo group included 18 males and 2 females with a mean age of 51.9 years. Results: Physical status including body weight, waist circumference and blood pressure and laboratory markers including metabolic parameters were not different at any observation point between the two groups. However, among participants with serum triglyceride levels of more than 120 mg/dl, body weight, waist circumference and serum triglyceride levels were significantly decreased at several observation points after the start of treatment in the sudachi peel group but not in the placebo group. No serious adverse events were observed in the sudachi peel group. Conclusions: Citrus sudachi peel has the potential effect to safely improve abdominal obesity and lower serum levels of TG in obese individuals with hypertriglyceridemia. A large-scale randomized, double-blind clinical study targeting subjects with both abdominal obesity and high TG levels is needed to confirm the metabolic effects of

In this, randomized, double-blind study, we evaluated the effectiveness of the addition of dexmedetomidine to varying concentration of levobupivacaine for supra clavicular brachial plexus block. Material and Methods: After obtaining ethical Committee approval, a double-blind, randomized prospective clinical study was conducted on 90 American Society of Anesthesiologist Grade I and II patients in the age group of 18-55 years, divided randomly into two groups: Group A received 40 ml of solution containing 30 ml 0.5% levobupivacaine and 10 ml 1% lignocaine and group B received 40 ml of solution containing 30 ml 0.25% levobupivacaine and 10 ml 1% lignocaine with dexmedetomidine 1 microg/kg for supraclavicular brachial plexus block. Besides effectiveness, other parameters observed were: duration of sensory blockade; onset and duration of motor blockade; duration of postoperative analgesia; and patient satisfaction score. Results: Onset of sensory and motor blockade was 7.6 ± 1.006 min and 8.3 ± 0.877 min in group A, while it was 6.96 ± 1.077 min an 7.6 ± 1.1 min in group B, respectively. The difference was statistically significant (P 0.05. Duration of motor block was 8.45 ± 0.75 h in group A and 5.6 ± 0.98 in group B (P < 0.05. Duration of analgesia was 8.5 ± 0.77 h in group A and 9.2 ± 1.05 in group B (P < 0.05. Conclusion: Addition of 1 microg/kg dexmedetomidine to 0.25% levobupivacaine for supraclaviclar plexus block shortens sensory, motor block onset time and motor block durations, extends sensory block, and analgesia durations. Reduction in total levobupivacaine dose also increases the safety margin of the block.

    In adults, mild traumatic brain injury (MTBI) frequently results in impairments of cognitive functions which would lead to psychological consequences in the future. Cerebrolysin is a nootropic drug, and can significantly improve cognitive function in patients with Alzheimer's disease and stroke. The purpose of this study was to investigate how Cerebrolysin therapy enhances cognitive recovery for mild traumatic brain injury patients using a double-blinded, placebo-controlled, randomized phase II pilot study. Patients having head injury within 24 h sent to our hospital were screened and recruited if patients were alert and conscious, and had intracranial contusion haemorrhage. From July 2009 to June 2010, totally, thirty-two patients were recruited in the double-blinded, placebo-controlled, and randomized study. Patients were randomized to receive Cerebrolysin (Group A, once daily intravenous infusion of 30 mL Cerebrolysin over a 60-min period for 5 days) or placebo (Group B, same dosage and administration of normal saline as Group A). The primary outcome measures were differences of cognitive function including Mini-Mental Status Examination (MMSE), and Cognitive Abilities Screening Instrument (CASI) scores between baseline and week 1, between baseline and week 4, and between baseline and week 12. Thirty-two patients completed the trial. For Group A, the CASI score difference between baseline and week 12 was 21.0 ± 20.4, a significantly greater change than that of Group B (7.6 ± 12.1) (p = 0.0461). Besides, drawing function (one of the domains of CASI; p = 0.0066) on week 4 and both drawing function (p = 0.0472) and long-term memory (one of the domains of CASI; p = 0.0256) on week 12 were also found to be significantly improved in the patients receiving Cerebrolysin treatment. Our results suggest that Cerebrolysin improves the cognitive function of the MTBI in patients at 3rd month after injury, especially for long-term memory and drawing function.

    Methylprednisolone pulse therapy (MPPT) has been shown to possess a long-lasting effect in other immune-inflammatory diseases without the well-known side effects caused by long-term treatment with glucocorticosteroids. In an attempt to reduce the long-term use of oral steroids in asthmatics, we conducted this double-blind, double-dummy study to compare the use of MPPT (1 g of methylprednisolone intravenously) (8 patients) with a short course of oral prednisolone (10 patients) in asthmatics presenting with acute severe asthma. Both treatments were effective in relieving the acute attack of asthma. The MPPT-treated patients did not show a faster resolution than did the orally treated group. No patients needed assisted ventilation, and no deaths occurred. One week after the treatment FEV1 tended to decrease in the methylprednisolone group compared with the oral prednisolone group (P = 0.06). The patients initially receiving MPPT needed supplementary prednisolone earlier and in higher doses than did the patients receiving oral prednisolone as initial treatment. At the end of the 12 weeks' study period, the groups reached identical FEV1. In conclusion, we did not find intravenous methylprednisolone superior to oral prednisolone in the treatment of acute attacks of severe asthma, but methylprednisolone pulse therapy had a shorter duration as regards protection against future asthma attacks.

    OBJECTIVE To evaluate the efficacy of Calendula officinalis in relation to Essential Fatty Acids for the prevention and treatment of radiodermatitis. METHOD This is a randomized double-blind controlled clinical trial with 51 patients with head and neck cancer in radiotherapy treatment divided into two groups: control (27) and experimental (24). RESULTS There is statistically significant evidence (p-value = 0.0120) that the proportion of radiodermatitis grade 2 in Essential Fatty Acids group is higher than Calendula group. Through the Kaplan-Meier survival curve we observed that Essential Fatty Acids group has always remained below the Calendula group survival curve, due to the lower risk of developing radiodermatitis grade 1, which makes the usage of Calendula more effective, with statistical significance (p-value = 0.00402). CONCLUSION Calendula showed better therapeutic response than the Essential Fatty Acids in the prevention and treatment of radiodermatitis. Brazilian Registry of Clinical Trials: RBR-237v4b.

    Full Text Available Background: The transverse abdominis plane (TAP block, a regional block provides effective analgesia after lower abdominal surgeries if used as part of multimodal analgesia. In this prospective, randomized double-blind study, we determined the efficacy of TAP block in patients undergoing cesarean section. Materials and Methods: Totally, 62 parturients undergoing cesarean section were randomized in a double-blind manner to receive either bilateral TAP block at the end of surgery with 20 ml of 0.25% bupivacaine or no TAP block, in addition to standard analgesic comprising 75 mg diclofenac 8 hourly and intravenous patient-controlled analgesia (PCA tramadol. Each patient was assessed at 0, 4, 8, 12, 24, 36, and 48 h after surgery by an independent observer for pain at rest and on movement using numeric rating scale of 0-10, time of 1 st demand for tramadol, total consumption of PCA tramadol, satisfaction with pain management and side effects. Results: Use of tramadol was reduced in patients given TAP block by 50% compared to patients given no block during 48 h after surgery (P < 0.001. Pain scores were lower both on rest and activity at each time point for 24 h in study group (P < 0.001, time of first analgesia was significantly longer, satisfaction was higher, and side effects were less in study group compared to control group. Conclusion: Transverse abdominis plane block was effective in providing analgesia with a substantial reduction in tramadol use during 48 h after cesarean section when used as adjunctive to standard analgesia.

    Full Text Available Abstract Background N-acetyl cysteine (NAC is a glutathione precursor that has been shown to have antidepressant efficacy in a placebo-controlled trial. The current study aimed to investigate the maintenance effects of NAC following eight weeks of open-label treatment for bipolar disorder. Method The efficacy of a double blind randomized placebo controlled trial of 2 g/day NAC as adjunct maintenance treatment for bipolar disorder was examined. Participants (n = 149 had a Montgomery Asberg Depression Rating Score of ≥12 at trial entry and, after eight weeks of open-label NAC treatment, were randomized to adjunctive NAC or placebo, in addition to treatment as usual. Participants (primarily outpatients were recruited through public and private services and through newspaper advertisements. Time to intervention for a mood episode was the primary endpoint of the study, and changes in mood symptoms, functionality and quality of life measures were secondary outcomes. Results There was a substantial decrease in symptoms during the eight-week open-label NAC treatment phase. During the subsequent double-blind phase, there was minimal further change in outcome measures with scores remaining low. Consequently, from this low plateau, between-group differences did not emerge on recurrence, clinical functioning or quality of life measures. Conclusions There were no significant between-group differences in recurrence or symptomatic outcomes during the maintenance phase of the trial; however, these findings may be confounded by limitations. Trial Registration The trial was registered with the Australian New Zealand Clinical Trials Registry (ACTRN12607000074493.

    AIM: To evaluate the efficacy and safety of capsule oxymatrine in the treatment of chronic hepatitis B.METHODS: A randomised double-blind and placebocontrolled multicenter trial was conducted. Injection of oxymatrine was used as positive-control drug. A total of 216 patients with chronic hepatitis B entered the study for 24 weeks, of them 108 received capsule oxymatrine, 36 received injection of oxymatrine, and 72 received placebo.After and before the treatment, clinical symptoms, liver function, serum hepatitis B virus markers, and adverse drug reaction were observed.RESULTS: Among the 216 patients, six were dropped off,and 11 inconsistent with the standard were excluded.Therefore, the efficacy and safety of oxymatrine in patients were analysed. In the capsule treated patients, 76.47 % became normal in ALT level, 38.61% and 31.91% became negative both in HBV DNA and in HBeAg. In the injection treated patients, 83.33 % became normal in ALT level,43.33 % and 39.29 % became negative both in HBV DNA and in HBeAg. In the placebo treated patients, 40.00 % became normal in ALT level, 7.46 % and 6.45 % became negative both in HBV DNA and in HBeAg. The rates of complete response and partial response were 24.51% and 57.84 % in the capsule treated patients, and 33.33 % and 50.00 % in the injection treated patients, and 2.99 % and 41.79 % in the placebo treated patients, respectively.There was no significance between the two groups of patients, but both were significantly higher than the placebo. The adverse drug reaction rates of the capsule,injection and placebo were 7.77 %, 6.67 % and 8.82 %,respectively. There was no statistically significant difference among them.CONCLUSION: Oxymatrine is an effective and safe agent for the treatment of chronic hepatitis B.

Iran J Child Neurol. 2014 Autumn;8(4: 18-27. AbstractObjectiveMigraines, a common health problem in children and adolescents, still do not have an FDA approved preventive treatment for patients under the age of 18 years. This study compares and contrasts the efficacy and safety of cinnarizine and topiramate in preventing pediatric migraines.Materials & MethodsIn this randomized, double-blind clinical trial 44 migrainous (from 4–15 years of age were equally allocated to receive cinnarizine or topiramate. The primary efficacy measure was monthly migraine frequency. Secondary efficacy measures were monthly migraine intensity and ≥ 50% responder rate. Efficacy measures were recorded at the baseline and at 4, 8, and 12 weeks of treatment.ResultsDuring the double-blind phase of the study, monthly migraine frequency and intensity were significantly decreased in both the cinnarizine and topiramate groups when compared to the baseline. However, at the end of the study, the cinnarizine group exhibits a significant decrease from the baseline in the mean monthly migraine intensity when compared to the topiramate group (4.7 vs. 3, respectively; 95% CI = -0.8 to -3.2.ConclusionNo significant difference between cinnarizine and topiramate was found for the prevention of pediatric migraines. Both treatments were well tolerated.ReferencesHershey AD, Winner PK. Pediatric Migraine: Recognition and Treatment. J Am Osteopath Assoc. 2005;105:2S-8.Lewis DW, Yonker M, Winner P, Sowell M.

    Schizophrenia is a persistent, lifelong illness such that enduring functional improvements may only occur over the course of years [corrected].This post hoc analysis in stable outpatients with schizophrenia investigated the negative symptom efficacy and treatment outcomes of ziprasidone (80-160 mg/d given twice a day, mean modal dose of 112 mg/d; and 80-120 mg/d given every day, mean modal dose of 96 mg/d) versus haloperidol (5-20 mg/d, mean modal dose of 12 mg/d) in a randomized, 40-week, double-blind study, followed by a double-blind continuation trial that extended up to 156 additional weeks. Symptomatic and functional recovery criteria were met when subjects attained both negative symptom remission and adequate psychosocial functioning based on the 4 Quality-of-Life subscales (instrumental role, interpersonal relations, participation in community, and intrapsychic foundations). Negative symptom remission (P = 0.005), as well as sustained adequate functioning (6 months) in instrumental role (P = 0.04) and participation in community (P = 0.02), was associated with significantly shorter time to remission in the ziprasidone 80 to 160 mg group than in the haloperidol group, as was the combination of symptomatic and functional recovery during the 196-week double-blind study period. A similar pattern was observed for the ziprasidone 80 to 120 mg group, which showed significant differences versus haloperidol in negative symptom remission and instrumental role functioning (but not other Quality-of-Life subscale measures). The clinically relevant outcome differences detected in this post hoc exploratory analysis support the potential for both enhanced remission in negative symptoms and psychosocial recovery during long-term treatment with an atypical agent and add to our understanding regarding the degree to which negative symptom remission can be attained in the maintenance phase.

    In adults, mild traumatic brain injury (MTBI) frequently results in impairments of cognitive functions which would lead to psychological consequences in the future. Cerebrolysin is a nootropic drug, and can significantly improve cognitive function in patients with Alzheimer's disease and stroke. The purpose of this study was to investigate how Cerebrolysin therapy enhances cognitive recovery for mild traumatic brain injury patients using a double-blinded, placebo-controlled, randomized phase II pilot study. Patients having head injury within 24 h sent to our hospital were screened and recruited if patients were alert and conscious, and had intracranial contusion haemorrhage. From July 2009 to June 2010, totally, thirty-two patients were recruited in the double-blinded, placebo-controlled, and randomized study. Patients were randomized to receive Cerebrolysin (Group A, once daily intravenous infusion of 30 mL Cerebrolysin over a 60-min period for 5 days) or placebo (Group B, same dosage and administration of normal saline as Group A). The primary outcome measures were differences of cognitive function including Mini-Mental Status Examination (MMSE), and Cognitive Abilities Screening Instrument (CASI) scores between baseline and week 1, between baseline and week 4, and between baseline and week 12. Thirty-two patients completed the trial. For Group A, the CASI score difference between baseline and week 12 was 21.0 ± 20.4, a significantly greater change than that of Group B (7.6 ± 12.1) (p = 0.0461). Besides, drawing function (one of the domains of CASI; p = 0.0066) on week 4 and both drawing function (p = 0.0472) and long-term memory (one of the domains of CASI; p = 0.0256) on week 12 were also found to be significantly improved in the patients receiving Cerebrolysin treatment. Our results suggest that Cerebrolysin improves the cognitive function of the MTBI in patients at 3rd month after injury, especially for long-term memory and drawing function. PMID:23656173

    Full Text Available Abstract Background The scaphoid bone is the most commonly fractured of the carpal bones. In the Netherlands 90% of all carpal fractures is a fracture of the scaphoid bone. The scaphoid has an essential role in functionality of the wrist, acting as a pivot. Complications in healing can result in poor functional outcome. The scaphoid fracture is a troublesome fracture and failure of treatment can result in avascular necrosis (up to 40%, non-union (5-21% and early osteo-arthritis (up to 32% which may seriously impair wrist function. Impaired consolidation of scaphoid fractures results in longer immobilization and more days lost at work with significant psychosocial and financial consequences. Initially Pulsed Electromagnetic Fields was used in the treatment of tibial pseudoarthrosis and non-union. More recently there is evidence that physical forces can also be used in the treatment of fresh fractures, showing accelerated healing by 30% and 71% reduction in nonunion within 12 weeks after initiation of therapy. Until now no double blind randomized, placebo controlled trial has been conducted to investigate the effect of this treatment on the healing of fresh fractures of the scaphoid. Methods/Design This is a multi center, prospective, double blind, placebo controlled, randomized trial. Study population consists of all patients with unilateral acute scaphoid fracture. Pregnant women, patients having a life supporting implanted electronic device, patients with additional fractures of wrist, carpal or metacarpal bones and pre-existing impairment in wrist function are excluded. The scaphoid fracture is diagnosed by a combination of physical and radiographic examination (CT-scanning. Proven scaphoid fractures are treated with cast immobilization and a small Pulsed Electromagnetic Fields bone growth stimulating device placed on the cast. Half of the devices will be disabled at random in the factory. Study parameters are clinical consolidation

    Background The authors found no study to compare the efficacy of bolus dose fentanyl and remifentanil blunting the cardiovascular intubation response in children, so they designed this randomized, double-blind clinical study to assess the effects of remifentanil 2 ug/kg and fentanyl 2 ug/kg by bolus injection on the cardiovascular intubation response in healthy children.Methods One hundred and two children, the American Society of Anesthesiologists (ASA) physical status 1-2 and scheduled for elective plastic surgery under general anesthesia, were randomly divided into one of two groups to receive the following treatments in a double blind manner: remifentanil 2 ug/kg (Group R) and fentanyl 2 ug/kg (Group F) when anesthesia was induced with propofol and vecuronium. The orotracheal intubation was performed using a direct laryngoscope. Blood pressure (BP) and heart rate (HR) were recorded before anesthesia induction (baseline values), immediately before intubation, at intubation and every minute for 5 minutes after intubation. The percent changes of systolic blood pressure (SBP) and HR relative to baseline values and the rate pressure product (RPP) at every observing point were calculated. The incidences of SBP and HR percent changes >30% of baseline values and RPP >22 000 during the observation were recorded. Results There were no significant differences between groups in the demographic data, baseline values of BP and HR and the intubation time. As compared to baseline values, BP, HR and RPP at intubation and their maximum values during observation increased significantly in Group F, but they all decreased significantly in Group R. BP, HR and RPP at all observed points, and their maximum values during the observation, were significantly different between groups. There were also significant differences between groups in the percent change of SBP and HR relative to baseline values at all observed points and their maximum percent changes during the observation.

    Full Text Available Homeopathy is a complementary and integrative medicine used in depression, The aim of this study is to investigate the non-inferiority and tolerability of individualized homeopathic medicines [Quinquagintamillesmial (Q-potencies] in acute depression, using fluoxetine as active control. Ninety-one outpatients with moderate to severe depression were assigned to receive an individualized homeopathic medicine or fluoxetine 20 mg day−1 (up to 40 mg day−1 in a prospective, randomized, double-blind double-dummy 8-week, single-center trial. Primary efficacy measure was the analysis of the mean change in the Montgomery & Åsberg Depression Rating Scale (MADRS depression scores, using a non-inferiority test with margin of 1.45. Secondary efficacy outcomes were response and remission rates. Tolerability was assessed with the side effect rating scale of the Scandinavian Society of Psychopharmacology. Mean MADRS scores differences were not significant at the 4th (P = .654 and 8th weeks (P = .965 of treatment. Non-inferiority of homeopathy was indicated because the upper limit of the confidence interval (CI for mean difference in MADRS change was less than the non-inferiority margin: mean differences (homeopathy-fluoxetine were −3.04 (95% CI −6.95, 0.86 and −2.4 (95% CI −6.05, 0.77 at 4th and 8th week, respectively. There were no significant differences between the percentages of response or remission rates in both groups. Tolerability: there were no significant differences between the side effects rates, although a higher percentage of patients treated with fluoxetine reported troublesome side effects and there was a trend toward greater treatment interruption for adverse effects in the fluoxetine group. This study illustrates the feasibility of randomized controlled double-blind trials of homeopathy in depression and indicates the non-inferiority of individualized homeopathic Q-potencies as compared to fluoxetine in acute treatment of

    Full Text Available The aim of this double-blind randomized clinical trial was to evaluate the efficacy of 1.23% APF gel application on the arrest of active incipient carious lesions in children. Sixty 7- to 12-year-old children, with active incipient lesions were included in the study. Children were divided randomly into 2 groups: 1.23% APF gel and placebo gel applications. Each group received 8 weekly applications of treatment. The lesions were re-evaluated at the 4th and 8th appointments. Poisson regression analysis was used to estimate relative risks of the presence of active white spot lesions. Groups showed similar results (PR = 1.67; CI 95% 0.69–3.98. The persistence of at least 1 active lesion was associated with a higher number of lesions in the baseline (PR = 2.67; CI 95% 1.19–6.03, but not with sugar intake (PR = 1.06; CI 95% 0.56–2.86 and previous exposure to fluoride dentifrice (PR = 1.26; CI 95% 0.49–2.29. The trial demonstrates the equivalence of the treatments. The use of the APF gel showed no additional benefits in this sample of children exposed to fluoridated water and dentifrice. The professional dental plaque removal in both groups may also account for the resulting equivalence of the treatments.

    Background: Radiofrequency (RF) is a minimally invasive target-selective technique that has been used with success for many years in the treatment of different pathologies, such as low back pain, trigeminal neuralgia, and others. Aim: The aim of this study is to compare different mode of RF - continuous RF (CRF) versus pulsed RF (PRF) along with steroid in the management of low back pain of discogenic origin. Setting and Design: Prospective, randomized, double-blind trial. Materials and Methods: Forty patients with chronic discogenic low back pain were randomized to receive CRF plus intradiscal triamcinolone 40 mg (Group 1) or to receive PRF plus intradiscal triamcinolone 40 mg (Group 2). Outcome measured includes immediate as well as long-term pain relief using visual analog scale, the Oswestry Disability Index and straight leg raising test. Statistical Analysis: The continuous variables were compared by one-way analysis of variance test. Discrete variables were compared by Fisher's exact test/Chi-square test/Student's t-test, whichever appropriate. The value of P PRF was insignificant. Conclusion: CRF with steroid seems to be better for treatment of chronic discogenic low back pain than PRF with steroid. PMID:27746559

    Full Text Available Abstract Background Antipyretic drugs are widely used in children with fever, though there is a controversy about the benefit of reducing fever in children with malaria. In order to assess the effect of ibuprofen on fever compared to placebo in children with uncomplicated Plasmodium falciparum malaria in Gabon, a randomized double blind placebo controlled trial, was designed. Methods Fifty children between two and seven years of age with uncomplicated malaria were included in the study. For the treatment of fever, all patients "received" mechanical treatment when the temperature rose above 37.5°C. In addition to the mechanical treatment, continuous fanning and cooling blanket, patients were assigned randomly to receive ibuprofen (7 mg/kg body weight, every eight hours or placebo. Results The fever clearance time using a fever threshold of 37.5°C was similar in children receiving ibuprofen compared to those receiving placebo. The difference was also not statistically significant using a fever threshold of 37.8°C or 38.0°C. However, the fever time and the area under the fever curve were significantly smaller in the ibuprofen group compared to the placebo group. Conclusion Ibuprofen is effective in reducing the time with fever. The effect on fever clearance is less obvious and depends on definition of the fever threshold.

    Full Text Available BACKGROUND: Most patients with facial scarring would value even a slight improvement in scar quality. Botulinum toxin A is widely used to alleviate facial dynamic rhytides but is also believed to improve scar quality by reducing wound tension during healing. The main objective was to assess the effect of Botulinum toxin on scars resultant from standardized upper lip wounds. METHODS: In this double-blinded, randomized, vehicle-controlled, prospective clinical trial, 60 consecutive consenting adults undergoing cleft lip scar revision (CLSR surgery between July 2010 and March 2012 were randomized to receive botulinum toxin A (n = 30 or vehicle (normal saline; n = 30 injections into the subjacent orbicularis oris muscle immediately after wound closure. Scars were independently assessed at 6-months follow-up in blinded fashion using: Vancouver Scar Scale (VSS, Visual Analogue Scale (VAS and photographic plus ultrasound measurements of scar widths. RESULTS: 58 patients completed the trial. All scar assessment modalities revealed statistically significantly better scars in the experimental than the vehicle-control group. CONCLUSION: Quality of surgical upper lip scars, which are oriented perpendicular to the direction of pull of the underlying orbicularis oris muscle, is significantly improved by its temporary paralysis during wound healing.

    The role of cholinergic abnormalities in autism was recently evidenced and there is a growing interest in cholinergic modulation, emerging for targeting autistic symptoms. Galantamine is an acetylcholinesterase inhibitor and an allosteric potentiator of nicotinic receptors. This study aimed to evaluate the possible effects of galantamine as an augmentative therapy to risperidone, in autistic children. In this randomized, double-blind, placebo-controlled, parallel-group study, 40 outpatients aged 4-12 years whom had a diagnosis of autism (DSM IV-TR) and a score of 12 or higher on the Aberrant Behavior Checklist-Community (ABC-C) Irritability subscale were equally randomized to receive either galantamine (up to 24 mg/day) or placebo, in addition to risperidone (up to 2 mg/day), for 10 weeks. We rated participants by ABC-C and a side effects checklist, at baseline and at weeks 5 and 10. By the study endpoint, the galantamine-treated patients showed significantly greater improvement in the Irritability (P = 0.017) and Lethargy/Social Withdrawal (P = 0.005) subscales than the placebo group. The difference between the two groups in the frequency of side effects was not significant. In conclusion, galantamine augmentation was shown to be a relatively effective and safe augmentative strategy for alleviating some of the autism-related symptoms.

    Summary Objective to investigate the efficacy and safety of a medicated plaster containing betamethasone valerate (BMV) 2.25 mg in patients with chronic elbow tendinopathy. Methods randomized, double-blind, placebo-controlled study with assignment 2:2:1:1 to BMV medicated plaster applied daily for 12 hours, daily for 24 hours or matched placebo. 62 patients aged ≥18 years with chronic lateral elbow tendinopathy were randomized. The primary efficacy variable was pain reduction (VAS) at day 28. Secondary objectives included summed pain intensity differences (SPID), overall treatment efficacy and tolerability. Results mean reduction in VAS pain score at day 28 was greater in both BMV medicated plaster groups, −39.35±27.69 mm for BMV12-h and −36.91±32.50 mm for BMV24-h, than with placebo, −20.20±27.32 mm. Considering the adjusted mean decreases, there was a statistically significant difference between BMV12-h and placebo (p=0.0110). Global pain relief (SPID) and overall treatment efficacy were significantly better with BMV. BMV and placebo plasters had similar local tolerability and there were few treatment-related adverse events. Conclusions BMV plaster was significantly more effective than placebo at reducing pain in patients with chronic elbow tendinopathies. The BMV plaster was safe and well tolerated. PMID:27331041

    This study was designed to compare the therapeutic effects of topical clotrimazole and systemic fluconazole in pityriasis versicolor. A double-blind randomized controlled trial was carried out in the dermatological clinic of Gorgan, northern Iran, between April 2006 and May 2007. All consecutive patients with pityriasis versicolor were included and randomly divided into two groups. In the first group (G1), patients underwent treatment with a single dose of fluconazole capsule (400 mg) and placebo cream. In the second group (G2), patients underwent treatment with clotrimazole cream (twice daily) and placebo capsule. The course of treatment was 2 weeks. All subjects were re-evaluated 2, 4 and 12 weeks after the end of the therapeutic course. After 2 weeks, the rate of complete resolution of disease was significantly higher in G2 than G1 (49.1% vs 30%). After 4 weeks, 41 patients (81.2%) of G1 and 52 patients (94.9%) of G2 showed complete resolution. After 12 weeks, 46 patients (92%) in G1 and 45 patients (81.8%) in G2 showed complete resolution. Recurrence rate in G1 and G2 were 6% and 18.2%, respectively. No complications were seen in either group. In this study, clinical response at week 4 was greater in the clotrimazole group than the fluconazole group. Recurrence at week 12 after treatment was less with oral fluconazole than clotrimazole cream. So, for better evaluation, more studies need to be done.

    Introduction. Actinic keratoses (AKs), a premalignant skin lesion, are a common lesion in fair skin. Although destructive treatment remains the gold standard for AKs, medical therapies may be preferable due to the comfort and reliability .This study aims to compare the effects of topical 1% colchicine gel and 3% diclofenac sodium gel in AKs. Materials and Methods. In this randomized double-blind study, 70 lesions were selected. Patients were randomized before receiving either 1% colchicine gel or 3% diclofenac sodium cream twice a day for 6 weeks. Patients were evaluated in terms of their lesion size, treatment complications, and recurrence at 7, 30, 60, and 120 days after treatment. Results. The mean of changes in the size was significant in both groups both before and after treatment ( 0.05). No case of erythema was seen in the colchicine group, while erythema was seen in 22.9% (eight cases) of patients in the diclofenac sodium group (p = 0.005). Conclusions. 1% colchicine gel was a safe and effective medication with fewer side effects and lack of recurrence of the lesion. PMID:27689135

    Full Text Available Purpose. This trial was performed to investigate the efficacy of laser acupuncture for the alleviation of lower back pain. Methods. This was a randomized, placebo-controlled, double-blind trial. Fifty-six participants were randomly assigned to either the laser acupuncture group (n=28 or the sham laser acupuncture group (n=28. Participants in both groups received three treatment sessions over the course of one week. Thirteen acupuncture points were selected. The visual analogue scale for pain, pressure pain threshold, Patient Global Impression of Change, and Euro-Quality-of-Life Five Dimensions questionnaire (Korean version were used to evaluate the effect of laser acupuncture treatment on lower back pain. Results. There were no significant differences in any outcome between the two groups, although the participants in both groups showed a significant improvement in each assessed parameter relative to the baseline values. Conclusion. Although there was no significant difference in outcomes between the two groups, the results suggest that laser acupuncture can provide effective pain alleviation and can be considered an option for relief from lower back pain. Further studies using long-term intervention, a larger sample size, and rigorous methodology are required to clarify the effect of laser acupuncture on lower back pain.

    In a double-blind, controlled trial with a factorial design, 684 patients (aged 6 months to 2 y; excludes 6 early dropouts) with acute watery diarrhoea of 3 d or less and some dehydration, who were attending a hospital, were randomly assigned to 4 groups to receive: (a) vitamin A 4500 microg retinol equivalent daily for 15 d; (b) 14.2 mg elemental zinc as acetate for the first 417 patients and 40 mg of the remaining 273 patients randomized to this group for 15 d; (c) both vitamin A 4500 microg retinol equivalent and zinc at the above doses daily for 15 d; or (d) placebo mixtures for 15 d. Patients were observed in the hospital for 24 h and followed up at home for 15 d. All received ascorbic acid 30 mg with each dose of medicine or placebo. Zinc supplementation was associated with a reduced duration of diarrhoea (13%, p = 0.03) and markedly reduced rate (43%, p = 0.017) of prolonged diarrhoea (>7 d). Vitamin A supplementation was associated with a nonsignificant trend for reduced rate of prolonged diarrhoea (p = 0.089). In conclusion, zinc supplementation as adjunct therapy had a substantial impact on the rate of prolonged diarrhoea and some impact on duration and may be beneficial in children with diarrhoea in developing countries.

    Full Text Available Eighty male patients with AGA, not treated in the previous 6 months were enrolled in this randomized, double blind, placebo controlled trial to assess the safety and efficacy of finasteride, 1mg daily, on hair growth. Patients were randomized into 2 groups: Group 1 received 1 mg of finasteride daily and Group 2 received a placebo for a period of 12 months. Efficacy was assessed by hair counts, photographic records, patient′s self-assessment questionnaire and clinical assessment. Safety was assessed by history taking and laboratory parameters. A total of 39 patients completed the study. Finasteride was rated superior to placebo with respect to all efficacy measures. At the end of study, finasteride treated patients had a mean increase of 20.56±4.73 hairs compared to a decrease of 9.56±5.53 hairs in placebo treated patients. Photographically, 69.56% of finasteride treated patients were rated as improved at 12 months compared to only 6.25% of placebo treated patients. Ten (25% of finasteride treated patients developed adverse effects (5-decreased libido as well as erectile dysfunction, 4-erectile dysfunction, 1-decreased libido. Finasteride in comparison to placebo was effective in promoting hair growth in male patients of AGA. However, the side effects to the drug were high in this study.

    Full Text Available Objective. This randomized double-blind study compared the analgesic efficacy and tolerability of etoricoxib versus ketoprofen in 165 patients with elective total primary knee arthroplasty. Methods. After ethical committee approval, 165 patients were randomized in 3 groups: the etoricoxib group (E receiving etoricoxib 120 mg/day, at the end of surgery and in the first postoperative day; the ketoprofen group (K receiving ketoprofen 2 pills of 100 mg/day, the first at the end of surgery and then 1 pill every 12 hours in the surgery day and the first postoperative day; the placebo group (P. All groups received postoperatively the same analgesia protocol when NRS is over 3 with IV Perfalgan and morphine. The effectiveness was evaluated by the time from the initiation of spinal anesthesia until the first analgesic dose, the total amount of morphine administered in the surgery day and the first postoperative day, and the frequency of patients with side effects and necessary amount of adjuvant medication. Results. The baseline demographic characteristics were similar among the 3 groups. In both study days etoricoxib provided an analgesic effect superior to placebo and to ketoprofen, the total administered morphine being significantly lower in etoricoxib group. There were no statistically significant differences between groups regarding the side effects.

    Full Text Available The intranasal low intensity GaInP/AlGaInP diode 650 nm laser therapy (ILGLT might improve blood lipid and hemorheologic behavior of patients in view of its previous research, but it should be further supported by a randomized, double-blind, and placebo-controlled clinical study. In this paper, 90 patients with coronary heart disease or cerebral infarction were randomly divided into two groups, 60 in the treatment group and 30 in the control group, and were blindly treated with ILGLT at 8.38 and 0 mW/cm2 for 30 min each time once a day ten days each session for two sessions between which there were three days for rest, respectively. Fasting blood lipid such as total cholesterol and low/high-density lipoprotein cholesterol and hemorheologic behavior such as blood viscosity, plasma viscosity, redox viscosity and red blood cell aggregation were assessed before the first treatment and after the two sessions and were found to be significantly improved by ILGLT. It was concluded that ILGLT may improve blood lipid and hemorheologic behavior of patients with coronary heart disease or cerebral infarction.

    Full Text Available Acute gastroenteritis is one of the most common infectious diseases of childhood. Its symptoms are vomiting, diarrhea, and dehydration. In the emergency ward, intravenous rather than oral rehydration is usually preferred because of the high likelihood of emesis. Treatments to reduce emesis are of value in improving the rehydration procedure. Our study is a double-blind randomized trial and proposes the use of ondansetron as an anti-emetic drug to treat children with acute gastroenteritis. Seventy-four in-patients, aged 3 months to 15 years, were enrolled and randomly assigned to an ondansetron or placebo group. Inclusion criteria were the diagnosis of acute gastroenteritis and the absence of other diseases or allergies to drugs. A single bolus (0.15 mg/kg of ondansetron was injected intravenously; normal 0.9% saline solution was used as a placebo. This treatment induced vomiting cessation in the ondansetron group significantly in comparison to the placebo group. The length of the hospital stay and the oral rehydration fluid volume were similar in the two groups and no adverse effects were noticed. Thus, safety, low cost, and overall bene­fit of ondansetron treatment suggests that this drug can be administered successfully to children with acute gastroenteritis.

    Full Text Available Several different plant extracts have been evaluated with respect to their antimicrobial effects against oral pathogens and for reduction of gingivitis. Given that a large number of these substances have been associated with significant side effects that contraindicate their long-term use, new compounds need to be tested. The aim of this study was to assess the short-term safety and efficacy of a Lippia sidoides ("alecrim pimenta"-based essential oil mouthrinse on gingival inflammation and bacterial plaque. Fifty-five patients were enrolled into a pilot, double-blinded, randomized, parallel-armed study. Patients were randomly assigned to undergo a 7-day treatment regimen with either the L. sidoides-based mouthrinse or 0.12% chlorhexidine mouthrinse. The results demonstrated decreased plaque index, gingival index and gingival bleeding index scores at 7 days, as compared to baseline. There was no statistically significance difference (p>0.05 between test and control groups for any of the clinical parameters assessed throughout the study. Adverse events were mild and transient. The findings of this study demonstrated that the L. sidoides-based mouthrinse was safe and efficacious in reducing bacterial plaque and gingival inflammation.

    Full Text Available Keloids are aesthetically disfiguring and severely disabling. The optimal treatment remains undefined. This clinical study, evaluate the efficacy and side effects of combined topical silicone and 5-Fluorouracil on the prevention of keloids. In this double blind randomized clinical trial, fifty patients with keloids were randomly allocated in two groups. The control group were treated by perilesional surgical excision of keloids combined with topical silicone and the trial group were treated with adjuvant treatment of intralesional 5-Fluorouracil. All patients were examined and assessment was done by an independent observer. the data collected were analyzed by SPSS statistical software with using tables and χ square tests. 75% of the cases in the trial group were keloid free 21% have keloid partially improvement and 4% have keloid recurrence, compared to patients in the control group respectively: 43%, 35% and 22%, findings suggest that efficacy of 5-Fluorouracil combined with topical silicone used for the prevention of keloid is comparable to other modality. The lack of any serious side effects and the evidence of recurrence at one year of follow-up make this an effective tool for the prevention of keloids.

    BACKGROUND Latrepirdine is an orally administered experimental small molecule that was initially developed as an antihistamine and subsequently was shown to stabilize mitochondrial membranes and function, which might be impaired in Huntington disease. OBJECTIVE To determine the effect of latrepirdine on cognition and global function in patients with mild to moderate Huntington disease. DESIGN Randomized, double-blind, placebo-controlled study. SETTING Sixty-four research centers in Australia, Europe, and North America. PATIENTS Four hundred three patients with mild to moderate Huntington disease and baseline cognitive impairment (Mini-Mental State Examination score, 10-26). INTERVENTION Latrepirdine (20 mg) vs matching placebo administered orally 3 times daily for 26 weeks. MAIN OUTCOME MEASURES The co-primary outcome measures were cognition as measured by the change in Mini-Mental State Examination score from baseline to week 26 and global function at week 26 as measured by the Clinician Interview-Based Impression of Change, plus carer interview, which ranges from 1 (marked improvement) to 7 (marked worsening). Secondary efficacy outcome measures included behavior, daily function, motor function, and safety. RESULTS The mean change in Mini-Mental State Examination score among participants randomized to latrepirdine (1.5-point improvement) did not differ significantly from that among participants randomized to placebo (1.3-point improvement) (P=.39). Similarly, the distribution of the Clinician Interview-Based Impression of Change, plus carer interview did not differ significantly among those randomized to latrepirdine compared with placebo (P=.84). No significant treatment effects were detected on the secondary efficacy outcome measures. The incidence of adverse events was similar between those randomized to latrepirdine (68.5%) and placebo (68.0%). CONCLUSION In patients with mild to moderate Huntington disease and cognitive impairment, treatment with

    The effect of a mangosteen product containing multivitamins and essential minerals was tested on immune function and well-being in healthy adults. A randomized, double blinded, placebo-controlled study was conducted in 59 healthy human subjects (40-60 years old). Changes from baseline immune function were measured after a 30-day consumption of the mangosteen product and the placebo. The subjects' self-appraisal of their health status was also surveyed. A xanthone-rich mangosteen product intake increased mean values for peripheral T-helper cell frequency (P = .020) and reduced the serum C-reactive protein concentration (P = .014). Increases in peripheral CD4/CD8 double-positive (DP) T-cell frequency and serum complement C3, C4, and interleukin (IL)-1alpha concentrations were significantly higher in the experimental group than in the placebo group (DP, P = .038; C3, P = .017; C4, P = .031; IL-1alpha, P = .006). At the end of study, serum IL-1alpha and IL-1beta concentrations in the study group were significantly higher than that in the placebo group (IL-1alpha, P = .033; IL-1beta, P = .04). Furthermore, more participants in the experimental group reported greatly improved overall health status compared with participants receiving placebo (P = .001). The results indicated that the intake of an antioxidant-rich product significantly enhanced immune responses and improved the subject's self-appraisal on his or her overall health status.

    The hormone oxytocin has been hypothesized to influence the emotional dimension of pain. This randomized, placebo-controlled, double-blind, crossover study explored whether intranasal oxytocin and emotional context can affect heat pain perception in 30 healthy male volunteers. After receiving 36 IU oxytocin or placebo, participants underwent functional Magnetic Resonance Imaging (fMRI) during which noxious and non-noxious thermode heat stimuli were applied. Simultaneously, scenes from the International Affective Pictures System (IAPS) with positive, neutral, and negative emotional valence were shown. Heat intensity and unpleasantness ratings were obtained. The activity of whole-brain correlates of heat processing was quantified via multi-voxel pattern analysis. We observed no appreciable main effects of oxytocin on ratings or neural pain correlates. Effects of emotional picture valence on ratings were smaller than reported in previous studies. Nevertheless, oxytocin was found to significantly enhance the influence of picture valence on unpleasantness ratings at noxious heat levels. No corresponding changes in whole-brain correlates of heat intensity processing were found. Our study provides evidence that intranasal oxytocin increases the effects of emotional context on the subjective unpleasantness of experimental heat pain. Future studies are needed to determine whether this effect can be utilized in clinical settings. PMID:27546446

    Alpha linolenic acid-enriched diacylglycerol (ALA-DAG) reduces visceral fat area and body fat in rodents and humans compared to conventional triacylglycerol (TAG). Although ALA-DAG increases dietary fat utilization as energy in rodents, its effects in humans are not known. The present study was a randomized, placebo-controlled, double-blind, crossover intervention trial performed to clarify the effect of ALA-DAG on postprandial energy metabolism in humans. Nineteen healthy subjects participated in this study, and postprandial energy metabolism was evaluated using indirect calorimetry followed by 14-d repeated pre-consumption of TAG (rapeseed oil) as a control or ALA-DAG. As a primary outcome, ALA-DAG induced significantly higher postprandial fat oxidation than TAG. As a secondary outcome, carbohydrate oxidation tended to be decreased. In addition, postprandial energy expenditure was significantly increased by ALA-DAG compared to TAG. These findings suggest that daily ALA-DAG consumption stimulates dietary fat utilization as energy after a meal, as well as greater diet induced thermogenesis in healthy humans. In conclusion, repeated consumption of ALA-DAG enhanced postprandial fat metabolism after a meal, which may partially explain its visceral fat area-reducing effect. PMID:27430386

    The blood-red sap of Dragon's blood has been used in folk medicine for fractures, wounds, inflammation, gastrointestinal disorders, rheumatism, blood circulation dysfunctions, and cancer. Existing in vitro and in vivo bioactivity of this herb on different mechanisms of healing shows strong potential of this sap in wound healing. This clinical trial study was designated to evaluate the wound healing effect of Dragon's blood on human wounds. Sixty patients, between the ages of 14-65 years, who were referred to remove their skin tag, were assigned to this double-blind, placebo-controlled, randomized clinical trial and received either Dragon's blood or a placebo cream. They were visited on the 3rd, 5th, 7th, 10th, 14th, and 20th day of the trial to check the process of healing and to measure the wound's surface. At the end of trial, there was a significant difference in the mean duration of wound healing between the two groups (p = 0.0001). The phenolic compounds and the alkaloid taspine, which exist in Dragon's-blood resin, are probably the main reasons for the wound healing property of this plant. Being natural accessible, safe, and affordable makes Dragon's blood cream, a good choice for addition to the wound healing armamentarium. Further studies on wounds with different causes and among larger populations are suggested to ensure the effectiveness and safety of Dragon's blood.

    Full Text Available Background: The benefit of prophylactic combination therapy using crystalloid and colloid preload with ephedrine has not been cleared to prevent maternal hypotension after spinal anesthesia at cesarean delivery. This study evaluated the efficacy of three combinational methods to prevent hypotension following spinal anesthesia. Materials and Methods: In this prospective double blind trial, 150 candidates of elective cesarean delivery under spinal anesthesia were randomly allocated to three treatment groups; 1---Ringer′s Lactate (RL solution (15 ml/kg plus Hemaxel (7 ml/kg preload, 2---RL solution (15 ml/kg preload plus ephedrine (15 mg, IV, bolus, 3---Hemaxel (7 ml/kg preload plus ephedrine (15 mg, IV, bolus. Maternal hemodynamic changes during 60 min after spinal injection, nausea/vomiting, and neonatal condition were compared among the groups. Results: The cumulative incidence of hypotension was 44%, 40%, and 46% in groups 1 to 3, respectively. There were not significant differences in supplementary ephedrine requirement among groups which received or among groups which did not receive prophylactic ephedrine. Groups were not different in the incidence of hypertension and nausea or vomiting. There were no significant differences among groups in Apgar scores at 1 or 5 min and umbilical artery PH. Conclusion: Combination of preventive methods decreased the occurrence of hypotension following spinal anesthesia to an acceptable level. Overall, the most effective method was a combination of crystalloid preload with ephedrine.

    EMLA cream is a topical formulation based upon the eutectic mixture of lidocaine and prilocaine and is used in clinical settings to produce local analgesia after application under occlusive dressing. A blanching reaction has been reported to occur locally after application, but it is not clear whether this reaction is caused by the anesthetic mixture, by the vehicle or the occlusion. We studied this blanching reaction in 50 healthy volunteers in a double-blind randomized assay: EMLA versus placebo, under occlusive dressing for 1 h, each subject being his own control. We found 33 cases (66%) of blanching after application of EMLA cream versus 3 cases (6%) after placebo, this difference being highly significant. Blanching was observed without delay, after removal of the dressing, and was very transient, disappearing in less than 3 h in all cases. We thus conclude that the blanching reaction is (1) frequent but very transient, and (2) determined by the anesthetic mixture included in EMLA cream and not by the vehicle alone, nor by the occlusion, since it is not found with the placebo. The precise mechanism of this reaction is unknown.

    Full Text Available Abstract Background Results of preclinical studies suggest that the GABAB receptor agonist baclofen may be useful in treatment of opioid dependence. This study was aimed at assessing the possible efficacy of baclofen for maintenance treatment of opioid dependence. Methods A total of 40 opioid-dependent patients were detoxified and randomly assigned to receive baclofen (60 mg/day or placebo in a 12-week, double blind, parallel-group trial. Primary outcome measure was retention in treatment. Secondary outcome measures included opioids and alcohol use according to urinalysis and self-report ratings, intensity of opioid craving assessed with a visual analogue scale, opioid withdrawal symptoms as measured by the Short Opiate Withdrawal Scale and depression scores on the Hamilton inventory. Results Treatment retention was significantly higher in the baclofen group. Baclofen also showed a significant superiority over placebo in terms of opiate withdrawal syndrome and depressive symptoms. Non-significant, but generally favorable responses were seen in the baclofen group with other outcome measures including intensity of opioid craving and self-reported opioid and alcohol use. However, no significant difference was seen in the rates of opioid-positive urine tests. Additionally, the drug side effects of the two groups were not significantly different. Conclusion The results support further study of baclofen in the maintenance treatment of opioid dependence.

    Previous studies suggested that pulsed electromagnetic field (PEMF) therapy can decrease pain. To date, however, it remains difficult to determine whether the analgesic effect observed in patients are attributable to a direct effect of PEMF on pain or to an indirect effect of PEMF on inflammation and healing. In the present study, we used an experimental pain paradigm to evaluate the direct effect of PEMF on pain intensity, pain unpleasantness, and temporal summation of pain. Twenty-four healthy subjects (mean age 22 ± 2 years; 9 males) participated in the experiment. Both real and sham PEMF were administered to every participant using a randomized, double-blind, cross-over design. For each visit, PEMF was applied for 10 minutes on the right forearm using a portable device. Experimental pain was evoked before (baseline) and after PEMF with a 9 cm(2) Pelletier-type thermode, applied on the right forearm (120 s stimulation; temperature individually adjusted to produce moderate baseline pain). Pain intensity and unpleasantness were evaluated using a 0-100 numerical pain rating scale. Temporal summation was evaluated by comparing pain intensity ratings obtained at the end of tonic nociceptive stimulation (120 s) with pain intensity ratings obtained after 60 s of stimulation. When compared to baseline, there was no change in pain intensity and unpleasantness following the application of real or sham PEMF. PEMF did not affect temporal summation. The present observations suggest that PEMF does not directly influence heat pain perception in healthy individuals. PMID:27014804

    Antidepressant medication is often associated with sexual side effects. A double-blind, placebo-controlled study in men with lifelong rapid ejaculation was performed to assess the effects of two selective serotonin (5-HT) reuptake inhibitors--paroxetine and sertraline--and the 5-HT2 antagonist and 5-HT/noradrenaline reuptake inhibitor nefazodone on the latency to ejaculate. Forty-eight men with an intravaginal ejaculation latency time (IELT) of a maximum of 1 minute were randomly assigned to receive paroxetine (20 mg/day), sertraline (50 mg/day), nefazodone (400 mg/day), or placebo for 6 weeks. During the 1-month baseline and 6-week treatment period, IELTs were measured at home with a stopwatch. The trial was completed by 40 men. During the 6-week treatment period, the geometric mean IELT in the placebo group was stable at approximately 20 seconds. Analysis of variance revealed a between-group difference in the evolution of IELT delay over time (p = 0.002); the IELT after paroxetine and sertraline gradually increased to approximately 146 and 58 seconds, respectively, compared with 28 seconds in the nefazodone group. The paroxetine and sertraline groups differed significantly (p < 0.001 and p = 0.024, respectively) from placebo, but the nefazodone group did not (p = 0.85). Compared with baseline, paroxetine exerted the strongest delay in ejaculation, whereas sertraline delayed it only moderately. There was no clinically relevant delay in ejaculation with nefazodone.

    This prospective, randomized, placebo-controlled, double-blinded study was designed to evaluate the efficacy of tropisetron in preventing postoperative nausea and vomiting after elective supratentorial craniotomy in adult patients. We studied 65 ASA physical status I-III patients aged 18 to 76 years who were undergoing elective craniotomy for resection of various supratentorial tumors. Patients were divided into two groups and received either 2 mg of tropisetron (group T) or saline placebo (group P) intravenously at the time of dural closure. A standard general anesthetic technique was used. Episodes of nausea and vomiting and the need for rescue antiemetic medication were recorded during 24 hours postoperatively. Demographic data, duration of surgery and anesthesia, and sedation scores were comparable in both groups. Nausea occurred in 30% of group T patients and in 46.7% of group P patients (P >.05). The incidence of emetic episodes was 26.7% and 56.7% in the two groups (P <.05). Rescue antiemetic medication was needed in 26.7% and 60% of the patients (P <.05). Administration of a single dose of tropisetron (2 mg intravenously) given at the time of dural closure was effective in reducing postoperative nausea and vomiting after elective craniotomy for supratentorial tumor resection in adult patients.

    Full Text Available OBJECTIVE: To examine the efficacy of ziprasidone vs. placebo for the depressive mixed state in patients with bipolar disorder type II or major depressive disorder (MDD. METHODS: 73 patients were randomized in a double-blinded, placebo-controlled study to ziprasidone (40-160 mg/d or placebo for 6 weeks. They met DSM-IV criteria for a major depressive episode (MDE, while also meeting 2 or 3 (but not more nor less DSM-IV manic criteria. They did not meet DSM-IV criteria for a mixed or manic episode. Baseline psychotropic drugs were continued unchanged. The primary endpoint measured was Montgomery-Åsberg Depression Rating Scale (MADRS scores over time. The mean dose of ziprasidone was 129.7±45.3 mg/day and 126.1±47.1 mg/day for placebo. RESULTS: The primary outcome analysis indicated efficacy of ziprasidone versus placebo (p = 0.0038. Efficacy was more pronounced in type II bipolar disorder than in MDD (p = 0.036. Overall ziprasidone was well tolerated, without notable worsening of weight or extrapyramidal symptoms. CONCLUSIONS: There was a statistically significant benefit with ziprasidone versus placebo in this first RCT of any medication for the provisional diagnostic concept of the depressive mixed state.

    Full Text Available Background: Adenotonsillectomy is one of the most frequent operations performed in hospitals worldwide. The aim this study is to investigate further the impact of antibiotics on co-morbidities post tonsillectomy. Methods: This prospective double blinded randomized controlled study was conducted at the department of otolaryngology in a tertiary care hospital where 300 tonsillectomy operations are performed each year. All Patients aged 2 years and older who were admitted for elective tonsillectomy from January 2012 to December 2012 were included in this study. Results: From the 128 patients enrolled in the study, 70 belonged to Group A (Intervention and 50 to Group 2 (Control. There was no statistically significant difference in the post-operative oral intake, fever in the first post operative day, degree of stress, secondary bleeding, otalgia, fever at home, and day of return to regular diet between the two groups. Conclusion: Although some studies showed that antibiotic use was beneficial in reducing morbidities post tonsillectomy, it is advisable for otolaryngologist to re- evaluate current practice taking into consideration bacterial resistance to antibiotics, adverse effects and cost benefit ratios. The use of antibiotics in post tonsillectomy patients will remain crucial in some selected cases.

    Full Text Available Objectives. Pneumonia is one of the common mortality causes in young children. Some studies have shown beneficial effect of zinc supplements on treatment of pneumonia. The present study aimed to investigate the effects of short courses of zinc administration on recovery from this disease in hospitalized children. Methods. In a parallel Double-Blind Randomized Controlled Trial at Ayatollah Golpaygani Hospital in Qom, 120 children aged 3–60 months with pneumonia were randomly assigned 1 : 1 to receive zinc or placebo (5 mL every 12 hours along with the common antibiotic treatments until discharge. Primary outcome was recovery from pneumonia which included the incidence and resolving clinical symptoms and duration of hospitalization. Results. The difference between two groups in all clinical symptoms at admittance and the variables affecting the disease such as age and sex were not statistically significant (P<0.05 at baseline. Compared to the placebo group, the treatment group showed a statistically significant decrease in duration of clinical symptoms (P=0.044 and hospitalization (P=0.004. Conclusions. Supplemental administration of zinc can expedite the healing process and results in faster resolution of clinical symptoms in children with pneumonia. In general, zinc administration, along with common antibiotic treatments, is recommended in this group of children. It can also reduce the drug resistance caused by multiple antibiotic therapies.

    Full Text Available Many patients experience pain and discomfort after colonoscopy. Carbon dioxide (CO2 can reduce periprocedural pain although air insufflation remained the standard procedure. The objective of this double-blinded, randomized controlled trial was to evaluate whether CO2 insufflation does decrease pain and bloating during and after colonoscopy compared to room air. Methods. 219 consecutive patients undergoing colonoscopy were randomized to either CO2 or air insufflation. Propofol was used in all patients for sedation. Transcutaneous CO2 was continuously measured with a capnograph as a safety parameter. Pain, bloating, and overall satisfaction were assessed at regular intervals before and after the procedure. Results(data are mean ±SD. 110 patients were randomized to CO2 and 109 to room air. The baseline characteristics were similar in both groups. The mean propofol dose was not different between the treatments, as were the time to reach the ileum and the withdrawal time. pCO2 at the end of the procedure was 35.2±4.3 mmHg (CO2 group versus 35.6±6.0 mmHg in the room air group (>.05. No relevant complication occurred in either group. There was significantly less bloating for the CO2 group during the postprocedural recovery period (<.001 and over the 24-hour period (<.001. Also, patients with CO2 insufflation experienced significantly less pain (=.014. Finally, a higher overall satisfaction (=.04 was found in the CO2 group. Conclusions. This trial provides compelling evidence that CO2 insufflation significantly reduces bloating and pain after routine colonoscopy in propofol-sedated patients. The procedure is safe with no significant differences in CO2 between the two groups.

    Many patients experience pain and discomfort after colonoscopy. Carbon dioxide (CO(2)) can reduce periprocedural pain although air insufflation remained the standard procedure. The objective of this double-blinded, randomized controlled trial was to evaluate whether CO(2) insufflation does decrease pain and bloating during and after colonoscopy compared to room air. Methods. 219 consecutive patients undergoing colonoscopy were randomized to either CO(2) or air insufflation. Propofol was used in all patients for sedation. Transcutaneous CO(2) was continuously measured with a capnograph as a safety parameter. Pain, bloating, and overall satisfaction were assessed at regular intervals before and after the procedure. Results(data are mean ±SD). 110 patients were randomized to CO(2) and 109 to room air. The baseline characteristics were similar in both groups. The mean propofol dose was not different between the treatments, as were the time to reach the ileum and the withdrawal time. pCO(2) at the end of the procedure was 35.2 ± 4.3 mmHg (CO(2) group) versus 35.6 ± 6.0 mmHg in the room air group (P > .05). No relevant complication occurred in either group. There was significantly less bloating for the CO(2) group during the postprocedural recovery period (P < .001) and over the 24-hour period (P < .001). Also, patients with CO(2) insufflation experienced significantly less pain (P = .014). Finally, a higher overall satisfaction (P = .04 ) was found in the CO(2) group. Conclusions. This trial provides compelling evidence that CO(2) insufflation significantly reduces bloating and pain after routine colonoscopy in propofol-sedated patients. The procedure is safe with no significant differences in CO(2) between the two groups. PMID:21747649

    Full Text Available Abstract Background and objectives: There are many studies conducted on reducing the frequency and severity of fentayl-induced cough during anesthesia induction. We propose that pheniramine maleate, an antihistaminic, may suppress this cough. We aim to observe the effect of pheniramine on fentanyl-induced cough during anesthesia induction. Methods: This is a double-blinded, prospective, three-arm parallel, randomized clinical trial of 120 patients with ASA (American Society of Anesthesiologists physical status III and IV who aged ≥18 and scheduled for elective open heart surgery during general anesthesia. Patients were randomly assigned to three groups of 40 patients, using computer-generated random numbers: placebo group, pheniramine group, and lidocaine group. Results: Cough incidence differed significantly between groups. In the placebo group, 37.5% of patients had cough, whereas the frequency was significantly decreased in pheniramine group (5% and lidocaine group (15% (Fischer exact test, p = 0.0007 and p = 0.0188, respectively. There was no significant change in cough incidence between pheniramine group (5% and lidocaine group (15% (Fischer exact test, p = 0.4325. Cough severity did also change between groups. Post Hoc tests with Bonferroni showed that mean cough severity in placebo differed significantly than that of pheniramine group and lidocaine group (p < 0.0001 and p = 0.009, respectively. There was no significant change in cough severity between pheniramine group and lidocaine group (p = 0.856. Conclusion: Intravenous pheniramine is as effective as lidocaine in preventing fentayl-induced cough. Our results emphasize that pheniramine is a convenient drug to decrease this cough.

  5. Randomized Double-Blind Placebo-Controlled Trial of Bevacizumab Therapy for Radiation Necrosis of the Central Nervous System

    International Nuclear Information System (INIS)

    Purpose: To conduct a controlled trial of bevacizumab for the treatment of symptomatic radiation necrosis of the brain. Methods and Materials: A total of 14 patients were entered into a placebo-controlled randomized double-blind study of bevacizumab for the treatment of central nervous system radiation necrosis. All patients were required to have radiographic or biopsy proof of central nervous system radiation necrosis and progressive neurologic symptoms or signs. Eligible patients had undergone irradiation for head-and-neck carcinoma, meningioma, or low- to mid-grade glioma. Patients were randomized to receive intravenous saline or bevacizumab at 3-week intervals. The magnetic resonance imaging findings 3 weeks after the second treatment and clinical signs and symptoms defined the response or progression. Results: The volumes of necrosis estimated on T2-weighted fluid-attenuated inversion recovery and T1-weighted gadolinium-enhanced magnetic resonance imaging scans demonstrated that although no patient receiving placebo responded (0 of 7), all bevacizumab-treated patients did so (5 of 5 randomized and 7 of 7 crossover) with decreases in T2-weighted fluid-attenuated inversion recovery and T1-weighted gadolinium-enhanced volumes and a decrease in endothelial transfer constant. All bevacizumab-treated patients-and none of the placebo-treated patients-showed improvement in neurologic symptoms or signs. At a median of 10 months after the last dose of bevacizumab in patients receiving all four study doses, only 2 patients had experienced a recurrence of magnetic resonance imaging changes consistent with progressive radiation necrosis; one patient received a single additional dose of bevacizumab and the other patient received two doses. Conclusion: The Class I evidence of bevacizumab efficacy from the present study in the treatment of central nervous system radiation necrosis justifies consideration of this treatment option for people with radiation necrosis secondary to

    Full Text Available Background: Oral aphthous is one of the most common oral mucosal inflammatory disorders which are very painful. There is no definite medical strategy up to now for aphthous treatment. Recently, some researchers have focused on immunomodulatory drugs such as tacrolimus and pimecrolimus in preventing aphthus recurrences. The aim of this study is to assess the effect of pimecrolimus cream against placebo in management of oral minor aphthous.Methods: The study is a randomized clinical trial, was done in “Shariati” hospital and Isfahan Skin Research Center. 62 patients with minor aphthuos were included and divided randomly to two groups (31 in each. In experimental group, pimecrolimus cream was applied for two weeks and cold cream for the same duration in control group. Patients were followed for 3 and one week; results were assessed in recovery after drug administration. Compared variables between two groups were including: the size of lesions, the time to recovery and pain intensity.Results: Results showed that mean size lesion in experimental and placebo group after complete recovery reduced (23.6 ±15.3 and 24.8 ±15 mm respectively but it was not significant (P: 0.1. Mean time for recovery in both groups was 8±2.2 and 9.5±2.5 respectively which was significant in pimecrolimus treated patients (P: 0.014. Also mean degree for pain intensity measured by pain scale method was reduced significantly in test group (6 ± 1.2 before treatment and 5.3 ± 1.1 after treatment, P<0.001.Conclusion: This study stated that pimecrolimus cream has an appropriate effect in reduction of recovery time and pain in minor aphthous compared to placebo but more clinical studies are needed to better conclusion.

    Full Text Available This was a randomized double-blinded study; in which 60 ASAI-II adult patients scheduled for major abdominal surgeries (colostomy, radical cystectomy, major gynecological surgery, and abdominal vascular surgery were received standard general anesthesia. Twenty minutes before the anticipated end of surgery, patients were randomized into two equal groups: dexmedetomidine group (group D and morphine group (group M. Group D received dexmedetomidine IV infusion 4µg/kg/h for 15 minutes (1µg/Kg followed by 0.4µg/kg/h for 3h. Group M received morphine sulfate IV (0.07mg/kg. All patients were given a morphine patient controlled analgesia (PCA pump in the post anesthesia care unit (PACU, delivering IV morphine 2mg with a lockout time of 5 minutes if pain score assessed through visual analog scale (VAS was more than 5 at any given 5-min assessment. During the PACU recovery period, morphine consumption; pain and sedation scores; hemodynamic variables (heart rate, mean arterial blood pressure, oxygen saturation and respiratory rate; and postoperative nausea, retching and vomiting (PONV were recorded every 30 min for 3h (study period by a member of staff blinded to the treatment. The study demonstrated that the use of dexmedetomidine led to significant decrease in the total amount of morphine consumed throughout the entire PACU recovery period (P0.05; significant decrease in mean arterial pressure (P0.05; without any significant changes in oxygen saturation (P<0.05 or respiratory rate (P<0.05. In conclusion, dexmedetomidine exhibited both analgesic and sedative properties. The associated cardiovascular protective pharmacological profile and the lack of respiratory depression made it potentially extremely interesting for postoperative analgesia after major abdominal surgeries.

    The efficacy and safety of a new centrally acting antitussive agent, isoaminile citrate, was compared with that of chlophedianol hydrochloride in a double-blind, randomized interpatient study. A total of 66 patients participated, two and four patients were lost to follow-up with isoaminile and chlophedianol, respectively. In the experimentally induced cough in 12 normal human subjects, isoaminile (40 mg) was as effective as chlophedianol (20 mg), but its duration of action was somewhat longer. One subject developed allergic skin rash with chlophedianol and was withdrawn from the study. In 60 patients with cough associated with chest diseases, isoaminile (40 mg, 3 x daily) was as effective as chlophedianol (20 mg, 3 x daily) in suppressing cough as judged from the 3-h and 24-h cough counts. The increase in PEFR at day 7 of treatment was somewhat more marked with chlophedianol as compared with isoaminile. None of the drugs interfered with the expectoration process. The side effects observed were few, mild in nature, and did not require a decrease in dose or withdrawal of treatment in any of the patients. Isoaminile citrate was concluded to be an effective and relatively safe antitussive agent. Isoaminile citrate, alpha(isopropyl)-alpha-(beta-dimethylaminoproyl) phenylacetonitrile citrate, is a centrally acting antitussive agent. In animal experiments this drug was as efficacious as codeine but was devoid of any respiratory depressant effect [Krause 1958, Kuroda et al. 1971]. This controlled double-randomized interpatient study was designed to test the comparative efficacy and safety of isoaminile and chlophedianol, another centrally acting antitussive, in humans.

    Shoulder pain is the third most common musculoskeletal problem and accounts for 5% of general practitioner consultations. Although many treatments are described, there is no consensus on optimal treatment and up to 40% of patients still have pain 12 months after initially seeking help for pain. Previously, the effect of transcutaneous pulsed radiofrequency treatment (TCPRFT) was evaluated in a retrospective audit that showed good pain relief for a mean 395 days and justified this randomized sham controlled trial. In this study, 51 patients entered into a randomized double-blinded, placebo controlled study of TCPRFT. Patients were assessed at 4 and 12 weeks by a blinded observer and compared with baseline. We observed sustained reductions in pain at night, pain with activity, and functional improvement at 4 and 12 weeks with active but not sham TCPRFT. The 25 subjects who received active treatment showed statistically significant reductions of 24/100 in pain at night and 20/100 of pain with activity at 4 weeks and 18/100 and 19/100, respectively, at 12 weeks from baseline. Statistically significant lower Brief Pain Inventory pain and function scores (4 and 12 weeks), improved pain self-efficacy (4 weeks), Oxford Shoulder scores (12 weeks), and internal rotation (12 weeks) were seen. Pain at both rest and shoulder elevation were not improved by active treatment. No complications were seen. This study of a simple, low risk, outpatient treatment confirms the findings of our earlier study of TCPRFT for knee pain and shoulder pain audit that transcutaneous pulsed radiofrequency treatment may help some people with painful shoulders.

  16. Radiotherapy plus nimotuzumab or placebo in the treatment of high grade glioma patients: results from a randomized, double blind trial

    International Nuclear Information System (INIS)

    The prognosis of patients bearing high grade glioma remains dismal. Epidermal Growth Factor Receptor (EGFR) is well validated as a primary contributor of glioma initiation and progression. Nimotuzumab is a humanized monoclonal antibody that recognizes the EGFR extracellular domain and reaches Central Nervous System tumors, in nonclinical and clinical setting. While it has similar activity when compared to other anti-EGFR antibodies, it does not induce skin toxicity or hypomagnesemia. A randomized, double blind, multicentric clinical trial was conducted in high grade glioma patients (41 anaplastic astrocytoma and 29 glioblastoma multiforme) that received radiotherapy plus nimotuzumab or placebo. Treatment and placebo groups were well-balanced for the most important prognostic variables. Patients received 6 weekly doses of 200 mg nimotuzumab or placebo together with irradiation as induction therapy. Maintenance treatment was given for 1 year with subsequent doses administered every 3 weeks. The objectives of this study were to assess the comparative overall survival, progression free survival, response rate, immunogenicity and safety. The median cumulative dose was 3200 mg of nimotuzumab given over a median number of 16 doses. The combination of nimotuzumab and RT was well-tolerated. The most prevalent related adverse reactions included nausea, fever, tremors, anorexia and hepatic test alteration. No anti-idiotypic response was detected, confirming the antibody low immunogenicity. The mean and median survival time for subjects treated with nimotuzumab was 31.06 and 17.76 vs. 21.07 and 12.63 months for the control group. In this randomized trial, nimotuzumab showed an excellent safety profile and significant survival benefit in combination with irradiation.

  17. The deception and fallacies of sponsored randomized prospective double-blinded clinical trials: the bisphosphonate research example.

    2014-01-01

    The randomized prospective double-blinded clinical trial (RCT) is accepted as Level I evidence and is highly regarded. However, RCTs that gained FDA approval of drugs such as Vioxx, Fen-Phen, and oral and intravenous bisphosphonates have proven to generate misleading results and have not adequately identified serious adverse reactions. The development, research, and clinical marketing of the oral and intravenous bisphosphonates can serve as a representative example for the deteriorated value of many of today's RCTs. The expected high value of RCTs is jeopardized by: (1) sponsorship that incorporates bias; (2) randomization that can select out an expected improved result or eliminate higher-risk individuals; (3) experimental design that can avoid recognition of serious adverse reactions; (4) blinding that can easily become unblinded by the color, shape, odor, or administration requirements of a drug; (5) definitions that can define an observation as something other than what it actually represents, or fail to define it as an adverse reaction; (6) labeling of retrospective data as a prospective trial by using adjudicators prospectively to look at retrospective data; (7) change of the length of study to avoid the longer-term adverse reaction from accumulation of drug or treatment effects; (8) ghost writing, as when drug company physicians or a hired corporation either edit or write the entire protocol and/or manuscript for publication. Such corruption of the well-intended properly conducted RCT should be viewed with a sense of outrage by practitioners and requires a restructuring of the levels of evidence accepted today.

    Background: Although the effectiveness of ginger as an antioxidant agent has been exploited, little human research has been conducted on its activity on male reproductive functions. Objective: This study was designed to investigate the effects of ginger (Zingiber officinale) on sperm DNA fragmentation (SDF) in infertile men. Materials and Methods: This randomized double-blind, placebo-controlled trial with a 1:1 allocation was performed on 100 infertility treatment candidates who were admitted to Royan Institute for Reproductive Biomedicine, Tehran, Iran. Patients were randomly assigned to receive one of two treatments: ginger and placebo. Patients were given a 3-month oral treatment (members received capsules containing 250 mg of ginger powder twice a day in ginger and a placebo in other group). Before and after treatment, standardized semen samples were obtained to determine sperm concentration, motility, and SDF according to World Health Organization. Results: There was no significant difference between two groups regarding SDF at baseline (53.48. 95%CI: 37.95-69.02) in cases and (56.75, 95%CI: 40.01-73.5) in controls. The average positive percentage of SDF in patients receiving ginger (17.77, 95%CI: 6.16-29.39) was lower compared with placebo (40.54, 95%CI: 23.94-57.13) after three month of treatment (p=0.02). In multivariate analysis, SDF was significantly lower in patients receiving ginger compared with placebo (mean difference: 3.21, 95%CI: 0.78-5.63, p=0.009). There were no significant differences between two groups regarding to semen parameters. Conclusion: The present study has demonstrated that ginger in a controlled study of efficacy was effective in decreasing SDF in infertile men. PMID:27679829

Objectives: Since some evidences reported that zinc has an important place amongst inhibitors of crystallization and crystal growth, we decided to assess the effectiveness of oral zinc sulfate as adjuvant treatment in children with nephrolithiasis. Patients and Methods: This was a randomized, double-blind, placebo-controlled clinical trial. 102 children in the age range 1 month to 11 years with first nephrolithiasis were recruited. Patients were randomly divided into two equal groups (intervention and control groups. Intervention group received conservative measures for stones and 1 mg/kg/day (maximum 20 mg/day oral zinc sulfate syrup for 3 months. Control group received placebo in addition to conservative measures, also for 3 months. Patients were followed up by ultrasonography for 9 months, in 5 steps (at the end of 1st, 2nd, 3rd, 6th and 9th month after treatment assessing size and number of stones in the kidneys. Results: Only at the end of the first month, the average number (intervention: 1.15 ± 3.78, control: 1.3 ± 2.84 (P = 0.001 and size (cm (intervention: 0.51 ± 1.76, control: 0.62 ± 1.39 (P = 0.001 of stones was significantly lower in the intervention group, and in other points there was no significant therapeutic efficacy in oral zinc adjuvant treatment compared to conservative treatment alone. Also, during the 9-month follow-up, the number and size of stones in both groups decreased significantly (both: P < 0.0001 in a way that the decrease in the intervention group showed no difference with the control group. Conclusions: Adjuvant treatment with zinc is not more effective than consecutive treatment in children with nephrolithiasis. However, further studies are recommended due to the lack of clinical evidence in this field.

    Full Text Available BACKGROUND AND AIMS: Obesity and its associated cardiometabolic co-morbidities are increasing worldwide. Since thyroid hormone mimetics are capable of uncoupling the beneficial metabolic effects of thyroid hormones from their deleterious effects on heart, bone and muscle, this class of drug is considered as adjacent therapeutics to weight-lowering strategies. This study investigated the safety and efficacy of TRC150094, a thyroid hormone mimetic. MATERIALS AND METHODS: This 4-week, randomized, placebo-controlled, double-blind trial was conducted in India and The Netherlands. Forty subjects were randomized at a 1:1 ratio to receive either TRC150094 dosed at 50 mg or placebo once daily for 4 weeks. Hyperinsulinemic euglycemic clamp and (1H-Magnetic Resonance Spectroscopy (MRS were performed before and after treatment. RESULTS: At baseline, subjects were characterized by markedly impaired hepatic and peripheral insulin sensitivity. TRC150094 dosed 50 mg once daily was safe and well tolerated. Hepatic nor peripheral insulin sensitivity improved after TRC150094 treatment, expressed as the suppression of Endogenous Glucose Production from 59.5 to 62.1%; p = 0.477, and the rate of glucose disappearance from 28.8 to 26.4 µmol kg(-1min(-1, p = 0.185. TRC150094 administration did not result in differences in fasting plasma free fatty acids from 0.51 to 0.51 mmol/L, p = 0.887 or in insulin-mediated suppression of lipolysis from 57 to 54%, p = 0.102. Also, intrahepatic triglyceride content was unaltered. CONCLUSION: Collectively, these data show that, in contrast to the potent metabolic effects in experimental models, TRC150094 at a dose of 50 mg daily does not improve the metabolic homeostasis in subjects at an increased cardiometabolic risk. Further studies are needed to evaluate whether TRC150094 has beneficial effects in patients with more severe metabolic derangement, such as overt diabetes mellitus and hypertriglyceridemia.

    Full Text Available Background : The addition of clonidine to lidocaine intravenous regional anesthesia (IVRA has been previously reported to improve postoperative analgesia in patients undergoing upper extremity surgery. Our objective was to perform a dose ranging study in order to determine the optimal dose of clonidine used with lidocaine in IVRA. Design & Setting : We performed a double-blinded randomized placebo-controlled study with 60 patients scheduled for elective endoscopic carpal tunnel release under IVRA with 50 ml lidocaine 0.5%. University-affiliated outpatient surgery center. Data collected in operating rooms, recovery room, and by telephone after discharge from surgery center. Materials & Methods : Sixty adult ASA I or II patients undergoing outpatient endoscopic carpal tunnel release under intravenous regional anesthesia.Patients were randomized into five study groups receiving different doses of clonidine in addition to 50 ml 0.5% lidocaine in their IVRA. Group A received 0 mcg/kg, group B 0.25 mcg/kg, group C 0.5 mcg/kg, group D 1.0 mcg/kg and group E 1.5 mcg/kg of clonidine.Intraoperative fentanyl, recovery room pain scores, time to first postsurgical analgesic, total number of acetaminophen/codeine tablets consumed postsurgery, incidence of sedation, hypotension and bradycardia. Results & Conclusions : There was no benefit from any dose of clonidine compared to placebo. There were no clonidine-related side effects seen within the dose range studied. In short duration minor hand surgery, the addition of clonidine to lidocaine-based intravenous regional anesthesia provides no measurable benefit.

    Introduction Mouthwashes are important means used in chemical control of dental plaque. There is strong evidence suggestive of better effectiveness, when fluoride is added to chlorhexidine mouthwash. Aim To assess the anti-plaque efficacy of Chlorhexidine combined with Fluoride mouthwash and to measure its impact on plaque accumulation and on plaque pH. Materials and Methods Initially 100 subjects were screened. A double blind, parallel randomized clinical trial was conducted on 30 subjects after applying inclusion and exclusion criteria. Other independent variables were matched before randomly allocating them in three groups: Group A-Chlorhexidine as positive control, Group B-Chlorhexidine + Fluoride as test group and Group C- Distilled water as negative control. Oral prophylaxis of participants was done before onset of the study. Plaque pH was assessed before and immediately after rinsing at 0, 5 and 10 minutes interval and after 7 days with digital pH electrode (pHepR pH meter, Hanna Instruments R10285) and accumulation of plaque was recorded by Turesky et al., modification of Quigley Hein Plaque Index (1970). ANOVA test was used for statistical analysis. Results Although there was a statistically significant reduction in mean plaque scores from baseline to seven days in both Groups A and B, Group B showed better anti-plaque efficacy . Almost equal drop in plaque pH was seen for both the groups at 5 and 10 minutes. Conclusion Better anti-plaque efficacy was observed in Group B (Chlorhexidine and Fluoride combination) with minimum variation of plaque pH.

    Full Text Available Professional firefighting is among the most demanding jobs. Prior studies have showed the notable prevalence of poor sleep quality among professional firefighters that may result in catastrophes. The aim of this study was in field confirmation of zolpidem usage (10 mg/PO/bed time for short term management of poor sleeps quality among professional firefighters. In a double-blind, randomized, placebo-controlled crossover clinical trial among professional firefighters, 27 poor sleepers were assigned randomly to one of the two groups. Two 14 days experimental periods were separated by a 14-day washout phase. Sleep quality was assessed using the Persian version of Pittsburgh Sleep Quality Index (PSQI. Six of the 27 enrolled voluntaries dropped out. Two rare side effects of zolpidem occurred in the study. A significant improvement of the PSQI score was detected in zolpidem period versus placebo in both groups (7.14 ± 3.02 vs 12.38 ± 2.51, PP=0.89. Zolpidem significantly improved all components of PSQI (Subjective sleep quality, Sleep latency, Sleep duration, Habitual sleep efficiency, Sleep disturbances and Daytime dysfunction in the current study except the use of sleep medication. Sleep onset latency was the component of PSQI with the greatest degree of abnormality among firefighters in a previous study. Interestingly, sleep latency was the component of PSQI with the most treatment effect of zolpidem in the current study. Zolpidem can be used as a part of treatment regimens in short time management of poor sleep quality among professional firefighters.

    Full Text Available Objective. To determine whether a combination of borage seed oil rich in gamma linolenic acid (GLA and fish oil rich in eicosapentaenoic acid (EPA and docosahexaenoic acid (DHA is superior to either oil alone for treatment of rheumatoid arthritis (RA. Methods. Patients were randomized into a double-blind, 18-month trial. Mixed effects models compared trends over time in disease activity measures. Results. No significant differences were observed in changes in disease activity among the three randomized groups. Each group exhibited significant reductions in disease activity (DAS28 at 9 months (fish: −1.56[−2.16, −0.96], borage: −1.33[−1.83, −0.84], combined: −1.18[−1.83, −0.54] and in CDAI (fish: −16.95[−19.91, −13.98], borage: −11.20[−14.21, −8.19], and combined: −10.31[−13.61, −7.01]. There were no significant differences in change of RA medications among the three groups. Reduced disease activity in study patients was similar to matched patients from an RA registry, and reduction in DMARD use was greater (P<0.03 in study patients. Conclusion. All 3 treatment groups exhibited similar meaningful clinical responses after 9 months, improvements which persisted for 18 months, and a response similar to matched patients from an RA registry. Study patients were able to reduce DMARD therapy given in combination with TNF antagonists to a greater extent than registry patients.

    Full Text Available Background: Patients with arrested preterm labor (PTL are at increased risk for recurrence ofpreterm birth (PTB. Maintenance tocolysis after arrest of acute PTL is of questionable value. Theobjective of this study was to evaluate the efficacy of 200 mg vaginal progesterone in order toprevent PTB in women with episodes of threatened PTL.Materials and Methods: This is a randomized double blind clinical trial study.Women with singletonpregnancies between 28-36 weeks of gestation, who were hospitalized for PTL were included. Atotal of 173 pregnant patients were randomly allocated to receive 200 mg vaginal progesteronesuppositories (n=86 or placebo (n=87 daily until the 36th gestational week. The two groups werecompared relative to demographic characteristics, incidence of PTB before 34 and 37 weeks, andmaternal and neonatal complications. Data were analyzed by chi-square and Fisher’s exact tests.Results: Mean latency until delivery in the cases was longer than the control group (23.88 ± 18.01vs. 16.67 ± 12.9; p=0.004.Treatment with progesterone was not associated with a reduction inthe rate of PTB before 34 weeks [cases: 9 (10.8% vs. controls: 8 (10%] and 37 weeks [cases: 45(54.2% vs. controls: 33 (41.2%]. Log rank analysis revealed a significant difference for mean timeto delivery between the two groups (p=0.028. There were no significant differences for neonataland maternal complications in the two groups.Conclusion: Prophylactic administration of 200 mg vaginal progesterone suppositories aftersuccessful tocolysis in patients with threatened idiopathic PTL is associated with a longer latencyto delivery, but failed to reduce the rate of PTB (Registeration Number: IRCT138706051096N1.

    Full Text Available Background: Prevention of rise in intraocular pressure (IOP is essential in patients undergoing surgery for perforated eye injuries. Metoclopramide, a prokinetic agent, is commonly used to hasten gastric emptying in emergency surgeries. Aim: To study the change in IOP after intravenous metoclopramide and to study the influence of metoclopramide on change in IOP after succinylcholine and tracheal intubation. Settings and Design: A randomized, double-blind, placebo-controlled study of 60 patients undergoing non-ophthalmic elective surgery. Materials and Methods: Sixty American Society of Anesthesiologists (ASA I adult patients were randomly assigned to receive normal saline (Group C or metoclopramide 10 mg (Group M 30 min before the induction of anesthesia. Thiopentone was used for induction and succinylcholine for tracheal intubation. Intraocular pressure was measured in both the eyes pre and post drug treatment and succinylcholine and tracheal intubation using Perkins applanation tonometer. Statistical Analysis: Student′s t-test and repeated measures ANOVA were used. A P value < 0.05 was considered as significant. Results: Intraocular pressure was consistently lower in Group M than in Group C after the test drug, though the difference was not statistically significant. Intraocular pressure decreased significantly after administration of thiopentone and increased significantly in Groups C and M after tracheal intubation ( P < 0.01. Intraocular pressure was comparable between the groups at all the times. Conclusions: Metoclopramide does not cause a clinically significant change in IOP nor does it influence the changes in IOP during anesthesia and tracheal intubation. Metoclopramide shows a trend towards decrease in IOP, though clinically insignificant. Therefore metoclopramide can be used to promote gastric emptying in patients with perforated eye injury.

    Full Text Available Current standardized treatments for cognitive impairment in attention-deficit/hyperactivity disorder remain limited and their efficacy restricted. Transcranial direct current stimulation (tDCS is a promising tool for enhancing cognitive performance in several neuropsychiatric disorders. Nevertheless, the effects of tDCS in reducing cognitive impairment in patients with attention-deficit/hyperactivity disorder (ADHD have not yet been investigated.A parallel, randomized, double-blind, sham-controlled trial was conducted to examine the efficacy of tDCS on the modulation of inhibitory control in adults with ADHD. Thirty patients were randomly allocated to each group and performed a go/no-go task before and after a single session of either anodal stimulation (1 mA over the left dorsolateral prefrontal cortex or sham stimulation.A nonparametric two-sample Wilcoxon rank-sum (Mann-Whitney test revealed no significant differences between the two groups of individuals with ADHD (tDCS vs. sham in regard to behavioral performance in the go/no go tasks. Furthermore, the effect sizes of group differences after treatment for the primary outcome measures-correct responses, impulsivity and omission errors--were small. No adverse events resulting from stimulation were reported.According to these findings, there is no evidence in support of the use of anodal stimulation over the left dorsolateral prefrontal cortex as an approach for improving inhibitory control in ADHD patients. To the best of our knowledge, this is the first clinical study to assess the cognitive effects of tDCS in individuals with ADHD. Further research is needed to assess the clinical efficacy of tDCS in this population.ClinicalTrials.gov NCT01968512.

    Huntington's disease (HD) is a neurodegenerative disease for which there is no curative treatment available. Given that the endocannabinoid system is involved in the pathogenesis of HD mouse models, stimulation of specific targets within this signaling system has been investigated as a promising therapeutic agent in HD. We conducted a double-blind, randomized, placebo-controlled, cross-over pilot clinical trial with Sativex(®), a botanical extract with an equimolecular combination of delta-9-tetrahydrocannabinol and cannabidiol. Both Sativex(®) and placebo were dispensed as an oral spray, to be administered up to 12 sprays/day for 12 weeks. The primary objective was safety, assessed by the absence of more severe adverse events (SAE) and no greater deterioration of motor, cognitive, behavioral and functional scales during the phase of active treatment. Secondary objectives were clinical improvement of Unified Huntington Disease Rating Scale scores. Twenty-six patients were randomized and 24 completed the trial. After ruling-out period and sequence effects, safety and tolerability were confirmed. No differences on motor (p = 0.286), cognitive (p = 0.824), behavioral (p = 1.0) and functional (p = 0.581) scores were detected during treatment with Sativex(®) as compared to placebo. No significant molecular effects were detected on the biomarker analysis. Sativex(®) is safe and well tolerated in patients with HD, with no SAE or clinical worsening. No significant symptomatic effects were detected at the prescribed dosage and for a 12-week period. Also, no significant molecular changes were observed on the biomarkers. Future study designs should consider higher doses, longer treatment periods and/or alternative cannabinoid combinations.Clincaltrals.gov identifier: NCT01502046. PMID:27159993

    Background: Fentanyl and dexmedetomidine have been tried to attenuate airway and circulatory reflexes during emergence and extubation individually but have not been compared with respect to the level of sedation to evolve a reliable technique for rapid and smooth extubation. Aim: To compare the effects of fentanyl and dexmedetomidine in attenuating airway and circulatory reflexes during emergence and extubation of the endotracheal tube. Setting and Design: This double-blind, randomized, controlled study was done in patients undergoing surgery under general anesthesia belonging to the American Society of Anesthesiologists physical status 1 or 2. Methodology: All patients received a standardized anesthetic protocol. Patients were randomized to receive either fentanyl 1 μg/kg or dexmedetomidine 0.75 μg/kg. Fifteen minutes before expected last surgical suture, isoflurane was cutoff and equal amount of test solution was given when train-of-four ratio was 0.3. The degree of sedation, airway, and circulatory responses at the time of suction and extubation were analyzed. Statistical Analysis Used: Chi-square test for nonparametric data and t-test for parametric data. Results: Heart rate (HR) was comparable in both the groups until endotracheal extubation. Later, there was rise in HR in fentanyl group. There was stastisticaly significant drop in blood pressure at 5 min after test drug administration in both the groups. Airway response for suctioning and extubation was better in dexmedetomidine group and it was associated with better sedation score than fentanyl group. Conclusion: Single dose of 0.75 μg/kg dexmedetomidine given 15 min before extubation provides smooth extubation when compared to fentanyl. PMID:27746558

    A total of 478 patients with endoscopically confirmed duodenal ulcer entered this randomized, parallel, double-blind trial. Patients were randomly assigned to receive ebrotidine (N-[(E)-[[2-[[[2-[(diaminomethylene)amino]- 4-thiazolyl]methyl]thio]ethyl]amino]methylene]-4-bromo-benzenesulfona mid e, CAS 100981-43-9, FI-3542) 400 mg or ranitidine 300 mg tablets (4:1) respectively, administered in single evening doses. Endoscopy, clinical examination and symptom assessment were performed at baseline and at weeks 4 and 8. Safety evaluations including laboratory tests, treatment compliance and antacid consumption checks were conducted at the beginning and/or at the 4 and 8 week visits. Patients whose ulcer showed endoscopic healing at the 4-week control left the study. Both groups were matched in all parameters studied. The healing rates at 4 weeks were 76.4% and 75.3% for ebrotidine and ranitidine respectively, while at 8 weeks the final rates were 95% and 91.8% respectively. Accompanying symptoms disappeared rapidly and the patients returned to normal. Smoking proved to be a highly significant negative risk factor, since healing rates were 83.4% and 71.2% at 4 weeks and 97.4% and 92.3% at 8 weeks in non-smokers and smokers respectively (p = 0.0046). Smokers treated with ranitidine showed significantly lower final healing rates than non-smokers (86% vs 100%; p = 0.0358), while the healing rates among patients treated with ebrotidine were similar regardless of whether they were smokers or not (93.9% and 96.7% N.S.). Ebrotidine (94%) proved to be more effective than ranitidine (86%) in smokers with higher healing rates (p < 0.05). Alcohol intake showed no significant relationship with the healing rates. Both drugs demonstrated an excellent safety. There were no changes in blood parameters, and no significant adverse events were reported.

    Full Text Available Most patients with fibromyalgia use complementary and alternative medicine (CAM. Properly designed controlled trials are necessary to assess the effectiveness of these practices. This study was a randomized, double-blind, placebo-controlled, early phase trial. Fifty patients seen at a fibromyalgia outpatient treatment program were randomly assigned to a daily soy or placebo (casein shake. Outcome measures were scores of the Fibromyalgia Impact Questionnaire (FIQ and the Center for Epidemiologic Studies Depression Scale (CES-D at baseline and after 6 weeks of intervention. Analysis was with standard statistics based on the null hypothesis, and separation test for early phase CAM comparative trials. Twenty-eight patients completed the study. Use of standard statistics with intent-to-treat analysis showed that total FIQ scores decreased by 14% in the soy group (P = .02 and by 18% in the placebo group (P < .001. The difference in change in scores between the groups was not significant (P = .16. With the same analysis, CES-D scores decreased in the soy group by 16% (P = .004 and in the placebo group by 15% (P = .05. The change in scores was similar in the groups (P = .83. Results of statistical analysis using the separation test and intent-to-treat analysis revealed no benefit of soy compared with placebo. Shakes that contain soy and shakes that contain casein, when combined with a multidisciplinary fibromyalgia treatment program, provide a decrease in fibromyalgia symptoms. Separation between the effects of soy and casein (control shakes did not favor the intervention. Therefore, large-sample studies using soy for patients with fibromyalgia are probably not indicated.

    Neuropathic pain and spasticity after spinal cord injury (SCI) represent significant problems. Palmitoylethanolamide (PEA), a fatty acid amide that is produced in many cells in the body, is thought to potentiate the action of endocannabinoids and to reduce pain and inflammation. This randomized, double-blind, placebo-controlled, parallel multicenter study was performed to investigate the effect of ultramicronized PEA (PEA-um) as add-on therapy on neuropathic pain in individuals with SCI. A pain diary was completed and questionnaires were completed before and after the 12-week treatment with either placebo or PEA-um. The primary outcome measure was the change in mean neuropathic pain intensity from the 1-week baseline period to the last week of treatment measured on a numeric rating scale ranging from 0 to 10. The primary efficacy analysis was the intention to treat (baseline observation carried forward). Secondary outcomes included a per protocol analysis and effects on spasticity, evoked pain, sleep problems, anxiety, depression, and global impression of change. We randomized 73 individuals with neuropathic pain due to SCI, of which 5 had a major protocol violation, and thus 68 were included in the primary analysis. There was no difference in mean pain intensity between PEA-um and placebo treatment (P = 0.46, mean reductions in pain scores 0.4 (-0.1 to 0.9) vs 0.7 (0.2-1.2); difference of means 0.3 (-0.4 to 0.9)). There was also no effect of PEA-um as add-on therapy on spasticity, insomnia, or psychological functioning. PEA was not associated with more adverse effects than placebo. PMID:27227691

    BACKGROUND: Tramadol has been administered peripherally to prolong analgesia after brachial plexus and neuraxial blocks. Our aim was to evaluate the systemic and perineural effects of tramadol as an analgesic adjunct to psoas compartment block (PCB) with levobupivacaine. METHODS: In a randomized, prospective, double-blinded trial, 60 patients (ASA I-III), aged 49-88 yr, undergoing primary total hip or knee arthroplasty underwent PCB and subsequent bupivacaine spinal anaesthesia. Patients were randomized into three groups. Each patient received PCB with levobupivacaine 0.5%, 0.4 ml kg(-1). The control group (group L, n=21) received i.v. saline, the systemic tramadol group (group IT, n=19) received i.v. tramadol 1.5 mg kg(-1) and the perineural tramadol group (group T, n=20) received i.v. saline and PCB with tramadol 1.5 mg kg(-1). Postoperatively patients received regular paracetamol 6-hourly and diclofenac sodium 12-hourly. Time to first morphine analgesia, 24-hour morphine consumption, sensory block, pain and sedation scores and haemodynamic parameters were recorded. RESULTS: Time (h) to first morphine analgesia was similar in the three groups [mean (SD)]: group L, 11.2 (6.6); group T, 14.5 (8.0); group IT, 14.6 (6.8); P=0.35. Twenty-four-hour cumulative morphine (mg) consumption was also similar in the three groups [group L, 21.9 (10.1); group T, 19.8 (6.7), group IT, 16.5 (9.5)], as were durations of sensory and motor block. There were no differences in the incidence of adverse effects except that patients in group IT were more sedated at 14 h than group L (P=0.02). CONCLUSION: We conclude that our data do not support a clinically important local anaesthetic or peripheral analgesic effect of tramadol as adjunct to PCB with levobupivacaine 0.5%.

    This multi-center, randomized, double-blind, phase 3 trial was conducted to compare the safety and efficacy of contrast agents iohexol-380 and iohexol-350 for coronary CT angiography in healthy subjects. Volunteers were randomized to receive 420 mgI/kg of either iohexol-350 or iohexol-380 using a flow rate of 4 mL/sec. All adverse events were recorded. Two blinded readers independently reviewed the CT images and conflicting results were resolved by a third reader. Luminal attenuations (ascending aorta, left main coronary artery, and left ventricle) in Hounsfield units (HUs) and image quality on a 4-point scale were calculated. A total of 225 subjects were given contrast media (115 with iohexol-380 and 110 with iohexol-350). There was no difference in number of adverse drug reactions between groups: 75 events in 56 (48.7%) of 115 subjects in the iohexol-380 group vs. 74 events in 51 (46.4%) of 110 subjects in the iohexol-350 group (p = 0.690). No severe adverse drug reactions were recorded. Neither group showed an increase in serum creatinine. Significant differences in mean density between the groups was found in the ascending aorta: 375.8 ± 71.4 HU with iohexol-380 vs. 356.3 ± 61.5 HU with iohexol-350 (p = 0.030). No significant differences in image quality scores between both groups were observed for all three anatomic evaluations (all, p > 0.05). Iohexol-380 provides improved enhancement of the ascending aorta and similar attenuation of the coronary arteries without any increase in adverse drug reactions, as compared with iohexol-350 using an identical amount of total iodine.

    Full Text Available "nVarious studies suggest that selective serotonin reuptake inhibitors (SSRIs may be useful in treating pathological skin picking (PSP. This study sought to assess effectiveness of citalopram in comparison with placebo in treating PSP. Forty five individuals with PSP were recruited in a four-week, randomized clinical trial of citalopram (20 mg/day in comparison with placebo. Study measures assessing skin picking severity, mental health status, obsessive compulsive disorder and quality of life were given at baseline, weeks 2 and 4. PSP severity, general health status, obsession-compulsion severity and quality of life level were similar between two groups at baseline (P > 0.05. Treatment analyses revealed significant improvements in quality of life, general health status and obsession-compulsion severity in citalopram group compared to placebo group (P < 0.05. Mean PSP severity reduction in citalopram group was more than placebo group but this difference was not significant. Citalopram can improve general health status and quality of life in individuals with PSP but its effect on skin picking behavior doesn't differ significantly with placebo. Other trials with longer time are needed to determine the exact efficacy of citalopram on PSP

  7. Morphine versus Nalbuphine for Open Gynaecological Surgery: A Randomized Controlled Double Blinded Trial

    Directory of Open Access Journals (Sweden)

    Shiv Akshat

    2014-01-01

    Full Text Available Introduction. Pain is the commonest morbidity after open surgical procedures. The most effective treatment of postoperative pain is opioid therapy. Morphine, the commonly used opioid, is associated with many side effects including respiratory depression, sedation, postoperative nausea vomiting, and pruritus. Nalbuphine, on the other hand, is known to cause less respiratory depression. Thus this study was undertaken to compare the intraoperative and postoperative analgesic efficacy and side effect profile of the two drugs. Methodology. 60 patients undergoing open gynaecological surgery were randomized to receive either morphine (Group M or nalbuphine (Group N in the intraoperative and postoperative period. Intraoperative analgesic efficacy (measured by need for rescue analgesics, postoperative pain by visual analogue scale, and side effects like postoperative nausea, vomiting, sedation, respiratory depression, and pruritus were compared in both groups. Intraoperative and postoperative heart rate and blood pressure were also compared between the groups. Results. Need for intraoperative analgesia was significantly more in Group N (P=0.023. Postoperative VAS scores were significantly different between the groups at various time points; however, none of the patients required any rescue analgesia. The incidence of various side effects was not significantly different between the groups. The haemodynamic profile of patients was comparable between the groups in both intraoperative and postoperative period. Conclusion. Nalbuphine provides less effective intraoperative analgesia than morphine in patients undergoing open gynaecological surgery under general anaesthesia. Both drugs, however, provided similar postoperative analgesia and had similar haemodynamic and side effect profile.

    Full Text Available Introduction: Remifentanil, with its rapid activity onset and short duration of action, may be more effective than other opioids for providing hemodynamic stability during obstetric anesthesia. However, there is some evidence of adverse effects on neonatal respiratory function. We investigated maternal and fetal effects of remifentanil during cesarean section surgery. Methods: Eighteen women with singleton term pregnancies, and physical class status of I or II as defined by the American Society of Anesthesia (ASA, who were undergoing general anesthesia for semi-elective cesarean section were randomized into two groups (40 in each group that received either and intravenous bolus of 0.5 µg/kg remifentanil or the same dose of saline as a placebo. Maternal hemodynamic variables and neonatal umbilical artery pH and Apgar score at first and fifth min were evaluated in both groups. Results: Systolic and diastolic blood pressure were significantly lower after tracheal intubation and skin incision in the remifentanil group as compared with the control group (p<0.05. There were no significant differences regarding heart rate between groups at any time (p>0.05. Apgar scores at first and fifth min were not significantly different among groups (p>0.05. No neonate required assisted ventilation or naloxan administration. Conclusion: Remifentanil may be a safe and effective drug for the induction of general anesthesia and surgical stimulation without subsequent neonatal depression.

    1993-01-01

    Full Text Available Fifty renal transplant patients were randomized to receive either 800 mg acyclovir by mouth four times daily or identical placebo tablets for prophylaxis of herpes simplex infection. Patients were followed weekly to assess reactivation of herpes simplex, varicella zoster virus, Epstein-Barr virus or cytomegalovirus (CMV infections. The patients received standard immunosuppressive regimens including cyclosporine A. Acyclovir suppressed secretion of herpes simplex virus in treated patients (P=0.001. Three episodes of mucocutaneous herpes simplex virus occurred in placebo recipients and one in a noncompliant acyclovir recipient. A clinically important difference in graft survival was demonstrated, but because of sample size failed to reach statistical significance (P=0.11. No reactivation of varicella zoster virus, Epstein-Barr virus or CMV infection was detected in either group. Toxicity was limited to central nervous irritability. The authors conclude that high dose oral acyclovir provides effective prophylaxis for prevention of herpes simplex virus infections in renal transplantation and may be associated with increased graft survival, perhaps from suppression of CMV infection.

    Background S-adenosyl-L-methionine (SAM) is the methyl donor for all methylation reactions and regulates the synthesis of glutathione (GSH), the main cellular antioxidant. Previous experimental studies suggested that SAM may benefit patients with established alcoholic liver diseases (ALD). The aim of this study was to determine the efficacy of SAM in treatment of ALD in a 24 week trial. The primary endpoints were changes in serum aminotransferase levels and liver histopathology scores, and the secondary endpoint was changes in serum levels of methionine metabolites. Methods We randomized 37 patients with ALD to receive 1.2 grams of SAM by mouth or placebo daily. Subjects were required to remain abstinent from alcohol drinking. A baseline liver biopsy was performed in 24 subjects and a post-treatment liver biopsy was performed in 14 subjects. Results Fasting serum SAM levels were increased over timed intervals in the SAM treatment group. The entire cohort showed an overall improvement of AST, ALT, and bilirubin levels after 24 weeks of treatment but there were no differences between the treatment groups in any clinical or biochemical parameters nor any intra- or intergroup differences or changes in liver histopathology scores for steatosis, inflammation, fibrosis, and Mallory-Denk hyaline bodies. Conclusions Whereas abstinence improved liver function, twenty-four weeks of therapy with SAM was no more effective than placebo in the treatment of ALD. PMID:22044287

    Oral leukoplakia is a potentially malignant lesion of the oral cavity, for which no effective treatment is available. We investigated the effectiveness of curcumin, a potent inhibitor of NF-κB/COX-2, molecules perturbed in oral carcinogenesis, to treat leukoplakia. Subjects with oral leukoplakia (n = 223) were randomized (1:1 ratio) to receive orally, either 3.6 g/day of curcumin (n = 111) or placebo (n = 112), for 6 months. The primary endpoint was clinical response obtained by bi-dimensional measurement of leukoplakia size at recruitment and 6 months. Histologic response, combined clinical and histologic response, durability and effect of long-term therapy for an additional six months in partial responders, safety and compliance were the secondary endpoints. Clinical response was observed in 75 (67.5%) subjects [95% confidence interval (CI), 58.4-75.6] in the curcumin and 62 (55.3%; 95% CI, 46.1-64.2) in placebo arm (P = 0.03). This response was durable, with 16 of the 18 (88.9%; 95% CI, 67.2-96.9) subjects with complete response in curcumin and 7 of 8 subjects (87.5%) in placebo arm, demonstrating no relapse after 6 months follow-up. Difference in histologic response between curcumin and placebo was not significant (HR, 0.88, 95% CI, 0.45-1.71; P = 0.71). Combined clinical and histologic response assessment indicated a significantly better response with curcumin (HR, 0.50; 95% CI, 0.27-0.92; P = 0.02). Continued therapy, in subjects with partial response at 6 months, did not yield additional benefit. The treatment did not raise any safety concerns. Treatment of oral leukoplakia with curcumin (3.6 g for six months), thus was well tolerated and demonstrated significant and durable clinical response for 6 months.

    Full Text Available : OBJECTIVE: Controlled hypotension is commonly used to achieve a bloodless operative field which is needed for successful FESS. This study was carried out to assess the hypotensive effect of dexmedetomidine (DEX during FESS. METHODS: Fifty ASA grades I and II patients of either sex aged 20–50 years undergoing FESS were randomly divided into two groups of 25 each. Group D received 10–15 min prior to induction of anesthesia 1 μg/kg IV bolus DEX diluted in 10 ml of normal saline over 10 min. Immediately thereafter an infusion of 0.4 μg/kg/hr of DEX commenced. Group C received placebo bolus and infusion of saline at a rate similar to DEX in Group D. Standard anesthetic technique was used. The surgical field was assessed using Average Category Scale and average blood loss was calculated. Hemodynamic variables (MAP and HR; emergence time and total recovery from anesthesia (Aldrete score ≥9 were recorded. RESULT: Group D reached the desired MAP (55-65 mmHg. In group D patients the average MAP was 55.9±5.3 mm of Hg, where as in group C it was 86.2±11.4 mm of Hg. Patients in group D had a better surgical field, and the duration of surgery was significantly reduced(78.34±16.7mins in group D vs 103.2±113.1 mins in group C The mean awakening time was significantly reduced in patients of Group D (9.1±2.7 mins in group D vs12.8±2.2 mins in group C when compared to patients of Group C. CONCLUSION: This study demonstrated that dexmedetomidine is a safe agent for controlled hypotension and is effective in providing ideal surgical field during FESS.

    The effect of metoclopramide on gastroesophageal reflux was studied in 30 infants less than 1 year of age. Gastroesophageal reflux was documented in all infants by extended pH monitoring before enrollment in the study. Patients were randomly assigned to receive metoclopramide 0.1 mg/kg or placebo four times a day, 1/2 hour before feeding for 1 week, followed by the alternate regimen for 1 week. The infants were reevaluated with extended pH monitoring and scintigraphy after 4 to 7 days of each treatment. A symptom score was derived by determining the average number of occurrences of all symptoms recorded daily by parents on a symptom checklist during pretreatment, placebo, and metoclopramide treatment periods. There was a difference between pretreatment evaluation and placebo periods with respect to daily symptom scores (p less than 0.005), reflecting a significant placebo response. However, no difference in scintigraphic study was found between placebo and metoclopramide periods. A significant difference between placebo and metoclopramide periods was noted in the percentage of time esophageal pH was less than 4.0 (p less than 0.001). However, although metoclopramide decreased the proportion of time esophageal pH was less than 4.0, pH remained less than 4.0 for more than 5% of the time in most patients. Substratification of the total group into infants younger and older than 3 months revealed that older infants had greater average daily weight gain during the metoclopramide treatment period (34.3 gm/day) than in the placebo treatment period (6.6 gm/day, p = 0.05). We conclude that metoclopramide in the dosage 0.1 mg/kg four times daily reduces reflux in infants and may be useful for infants with poor weight gain and other serious complications of gastroesophageal reflux.

    Full Text Available Stroke is a leading cause of death and disability in the USA. Up to 60% of patients do not fully recover despite intensive physical therapy treatment. N-Methyl-D-aspartate receptors (NMDA-R have been shown to play a role in synaptic plasticity when activated. D-Cycloserine promotes NMDA receptor function by binding to receptors with unoccupied glycine sites. These receptors are involved in learning and memory. We hypothesized that D-cycloserine, when combined with robotic-assisted physiotherapy (RAP, would result in greater gains compared with placebo + RAP in stroke survivors. Participants (n=14 were randomized to D-cycloserine plus RAP or placebo plus RAP. Functional, cognitive, and quality-of-life measures were used to assess recovery. There was significant improvement in grip strength of the affected hand within both groups from baseline to 3 weeks (95% confidence interval for mean change, 3.95 ± 2.96 to 4.90 ± 3.56 N for D-cycloserine and 5.72 ± 3.98 to 8.44 ± 4.90 N for control. SIS mood domain showed improvement for both groups (95% confidence interval for mean change, 72.6 ± 16.3 to 82.9 ± 10.9 for D-cycloserine and 82.9 ± 13.5 to 90.3 ± 9.9 for control. This preliminary study does not provide evidence that D-cycloserine can provide greater gains in learning compared with placebo for stroke survivors.

    Full Text Available Abstract Background Procedural pain relief is sub-optimal in infants, especially small and vulnerable ones. Tetracaine gel 4% (Ametop®, Smith-Nephew provides pain relief in children and larger infants, but its efficacy in smaller infants and for peripherally inserted central catheters (PICC remains uncertain. The objective of this trial was to assess the safety and efficacy of tetracaine gel on the pain response of very low birth weight (VLBW infants during insertion of a PICC. Methods Medically stable infants greater than or equal to 24 weeks gestation, requiring a non-urgent PICC, were included. Following randomization and double blinding, 1.1 g of tetracaine or placebo was applied to the skin for 30 minutes. The PICC was inserted according to a standard protocol. Pain was assessed using the Premature Infant Pain Profile (PIPP. A 3-point change in the pain score was considered clinically significant, leading to a sample size of 54 infants, with 90% statistical power. Local skin reactions and immediate adverse cardiorespiratory events were noted. The primary outcome, PIPP score at 1 minute, was analysed using an independent Student's t-test. Results Fifty-four infants were included, 27 +/- 2 weeks gestation, 916 +/- 292 grams and 6.5 +/- 3.2 days of age. Baseline characteristics were similar between groups. The mean PIPP score in the first minute was 10.88 in the treatment group as compared to 11.74 in the placebo group (difference 0.86, 95% CI -1.86, 3.58. Median duration of crying in non-intubated infants was 181 seconds in the tetracaine group compared to 68 seconds in the placebo group (difference -78, 95% CI -539, 117. Local skin erythema was observed transiently in 4 infants (3 in the treatment and 1 in the placebo group. No serious harms were observed. Conclusion Tetracaine 4% when applied for 30 minutes was not beneficial in decreasing procedural pain associated with a PICC in very small infants.

    Full Text Available Abstract Background Procedural pain relief is sub-optimal in neonates. Topical tetracaine provides pain relief in children. Evidence of its efficacy and safety in neonates is limited. The objective of this study was to assess the efficacy and safety of topical tetracaine on the pain response of neonates during a venipuncture. Methods Medically stable infants greater than or equal to 24 weeks gestation, requiring a venipuncture, were included. Following randomization and double blinding, 1.1 g of tetracaine or placebo was applied to the skin for 30 minutes. Participants received oral sucrose if they met local eligibility criteria. The venipuncture was performed according to a standard protocol. A medium effect size in the pain score (corresponding to about 2 point difference in the PIPP score was considered clinically significant, leading to a sample size of 142 infants, with 80% statistical power. Local skin reactions and immediate adverse cardiorespiratory events were noted. The primary outcome, PIPP score at 1 minute, was analysed using an independent Student's t-test. Results One hundred and forty two infants were included, 33 +/- 4 weeks gestation, 2100 +/- 900 grams and 6 +/- 3 days of age. There was almost no difference in PIPP scores at 1 minute between groups (mean difference -0.09; 95% confidence interval [CI]: -1.68 to 1.50; P = . 91. Similarly, there were no differences in PIPP scores during the 2nd, 3rd and 4th minute. Duration of cry did not differ between the groups (median difference, 0; 95% CI, -3 to 0; P = . 84. The majority of infants in both groups received sucrose 24%. Sucrose had a significant effect on the PIPP score, as assessed by an ANOVA model (p = 0.0026. Local skin erythema was observed transiently in 11 infants (7 in the tetracaine and 4 in the placebo group. No serious side effect was observed. Conclusion Tetracaine did not significantly decrease procedural pain in infants undergoing a venipuncture, when used in

    An estimated 15% of patients with diabetes will develop a foot ulcer sometime in their life, making them 30 to 40 times more likely to undergo amputation due to a non-healing foot ulcer than the non-diabetic population. To determine the safety and efficacy of a new, non-contact, kilohertz ultrasound therapy for the healing of recalcitrant diabetic foot ulcers - as well as to evaluate the impact on total closure and quantitative bacterial cultures and the effect on healing of various levels of sharp/surgical debridement - a randomized, double-blinded, sham-controlled, multicenter study was conducted in hospital-based and private wound care clinics. Patients (55 met criteria for efficacy analysis) received standard of care, which included products that provide a moist environment, offloading diabetic shoes and socks, debridement, wound evaluation, and measurement. The "therapy" was either active 40 KHz ultrasound delivered by a saline mist or a "sham device" which delivered a saline mist without the use of ultrasound. After 12 weeks of care, the proportion of wounds healed (defined as complete epithelialization without drainage) in the active ultrasound therapy device group was significantly higher than that in the sham control group (40.7% versus 14.3%, P = 0.0366, Fisher's exact test). The ultrasound treatment was easy to use and no difference in the number and type of adverse events between the two treatment groups was noted. Of interest, wounds were debrided at baseline followed by a quantitative culture biopsy. The results of these cultures demonstrated a significant bioburden (greater than 10(5)) in the majority of cases, despite a lack of clinical signs of infection. Compared to control, this therapeutic modality was found to increase the healing rate of recalcitrant, diabetic foot ulcers.

    Objective: To compare effect of Hypericum perforatum (H. perforatum) vaginal gel with metronidazole on bacterial vaginosis (BV) in terms of initial response to treatment and preventing recurrence (primary outcomes) and also patient complaints (secondary outcomes). Methods: In this double-blind, double dummy trial, married women aged 18-49 with BV were randomized into two groups and administered 5 g of 3% H. perforatum and placebo of metronidazole (n=82), or 5 g of 0.75% metronidazole and placebo of H. perforatum (n=80) vaginally for 5 d. Amsel criteria were used for diagnosis and assessing cure and recurrence of BV. The comparisons was done using Chi-square, Fisher's exact and logistic regression.Results:At 10-12 d, cure rate was 82% in the H. perforatum and 85% in metronidazole group (risk ratio 0.9, 95% confidence interval 0.6 to 1.3). Among the cured women, recurrence rate was 9%in the H. perforatum and 13% in the metronidazole group at the 30-35 d visit (risk ratio 0.8, 95%confidence interval 0.4 to 1.3). There was no statistically significant difference between the groups regarding any patient complaints, except itching which was less in H. perforatum group (5% vs. 16%, P=0.018 at the first and 13% vs. 43%, P<0.001 at the second follow-up). No significant adverse event was reported at any groups. Conclusions: H. perforatum could be a good option for treatment of BV. However, further studies are needed for its public use.

    Full Text Available Objective: Despite the development of effective systemic treatments and new biological agents for psoriasis nowadays, topical medications are still the mainstay of treatment. Topical calcineurin inhibitors are currently used in various skin diseases. We investigated The efficacy and safety of tacrolimus, which is an alternative in topical treatment, is investigated in comparison with the present medications in plaque psoriasis. Material and Methods: This prospective double-blind plasebo-controlled study was conducted in 24 patients with diagnosis of plaque psoriasis who were seen in X University Hospital dermatology outpatient clinic. 0.1% tacrolimus ointment, 0.1% mometasone furoate ointment, 0,005% calcipotriol ointment and plasebo in encrypted bottles, were randomly applied in test chambers under occlusion, in every other day, during 19 days, to 27 psoriatic plaques. Clinic sum scores, side effects, epidermal thickness measured by superficial ultrasound were noted before and after treatment in all microplaques. Besides histopathologic scoring and epidermal thickness were measured in 9 patients at the end of study. Results: The clinic sum scores and ultrasonographic epidermal thickness at the end were both significantly lower than the beginning values in all microplaques (p˂0.05. The reduction in these two values with tacrolimus were significantly higher than plasebo (p˂0.001, but no difference with calcipotriol (p=0.287, p=0.813, respectively. On the other hand, the reduction in these values with mometasone were significantly higher than tacrolimus (p˂0.05. Mometasone furoate was the most effective when the difference of total histopathological score and epidermal thickness of the three ointments from plasebo at the end were compared. Conclusion: Tacrolimus ointment is an alternative topical medication in plaque psoriasis under occlusion. Occlusion in practice requires patients compliance. Thus studies to find a a new formulation that will

    Full Text Available Objective:Constipation is a common problem in children. There is some clinical evidence for the role of probiotics and prebiotics in the treatment of constipated children. This is the first study on the therapeutic effect of synbiotics (combination of probiotics and prebiotic in treatment of childhood constipation. Methods:In a double-blind randomized placebo controlled study 102 children aged 4-12 years with functional constipation were assessed according to Rome III criteria for 4 weeks. They were divided into 3 groups: Group A, received 1.5 ml/kg/day oral liquid paraffin plus placebo, group B, 1 sachet synbiotic per day plus placebo and group C, 1.5 ml/kg/day oral liquid paraffin plus 1 sachet synbiotic per day. Frequency of bowel movements (BMs, stool consistency, number of fecal incontinence episodes, abdominal pain, painful defecation per week, success of treatment and side effects were determined in each group before and after treatment. Findings:The frequency of BMs per week increased in all groups (P<0.001, but it differed between groups and was higher in group C (P=0.03. Stool consistency increased and number of fecal incontinence episodes, abdominal pain and painful defecation per week decreased in all groups similarly and there was statistically no difference between them. No side effects were reported in group B; the main side effect in group A and C was seepage of oil (P<0.001. Treatment success was similar in all groups without any significant difference between them (P=0.6.   Conclusion:This study showed that synbiotics have positive effects on symptoms of childhood constipation without any side effects.

    Full Text Available Japanese encephalitis (JE virus (JEV is a mosquito-borne flavivirus found across Asia that is closely related to West Nile virus. There is no known antiviral treatment for any flavivirus. Results from in vitro studies and animal models suggest intravenous immunoglobulin (IVIG containing virus-specific neutralizing antibody may be effective in improving outcome in viral encephalitis. IVIG's anti-inflammatory properties may also be beneficial.We performed a pilot feasibility randomized double-blind placebo-controlled trial of IVIG containing anti-JEV neutralizing antibody (ImmunoRel, 400mg/kg/day for 5 days in children with suspected JE at two sites in Nepal; we also examined the effect on serum neutralizing antibody titre and cytokine profiles. 22 children were recruited, 13 of whom had confirmed JE; 11 received IVIG and 11 placebo, with no protocol violations. One child (IVIG group died during treatment and two (placebo subsequently following hospital discharge. Overall, there was no difference in outcome between treatment groups at discharge or follow up. Passive transfer of anti-JEV antibody was seen in JEV negative children. JEV positive children treated with IVIG had JEV-specific neutralizing antibody titres approximately 16 times higher than those treated with placebo (p=0.2, which was more than could be explained by passive transfer alone. IL-4 and IL-6 were higher in the IVIG group.A trial of IVIG for JE in Nepal is feasible. IVIG may augment the development of neutralizing antibodies in JEV positive patients. IVIG appears an appealing option for JE treatment that warrants further study.ClinicalTrials.gov NCT01856205.

    Full Text Available Background: The beneficial effects of Lactobacillus species have been reported but the role of these species including Lactobacillus casei (L. casei on oral health is not well documented. The purpose of this study was to evaluate the ef-fects of conventional or probiotic cheese containing L.casei on salivary Streptococcus mutans (SM and Lactobacilli levels. Methods: In this double-blind controlled trial (IRCT201009144745N1, 60 adults were randomly allocated in 2 paral-lel blocks. SM and Lactobacilli count assessment were performed three times. Subjects consumed either cheese contain-ing L. casei (110[6] Cfu /g (probiotic block, n=29 or cheese without any probiotic (control block, n=31 twice daily for two weeks. Bacterial levels changes were compared using Wilcoxon and Mann-Whitney Tests. Logistic regression compared changes in number of subjects with lowest and highest SM or Lactobacilli levels. Results: Statistically significant (p = 0.001 reduction of salivary SM was found in probiotic group. SM levels reduc-tion was not significant between placebo and trial groups (p = 0.46, 62% in probiotic vs. 32% in placebo group. Lacto-bacilli count changes during trial were not statistically significant inter and intra blocks (p = 0.12. Probiotic interven-tion was significantly effective in high levels (> 10[5] cfu/ml of SM (Odds Ratio 11.6, 95% CI 1.56-86.17, p = 0.017. Conclusions: Probiotic cheese containing L. casei was not effective in salivary SM levels reduction comparing to conventional cheese. Adding L. casei to cheese could be useful in decreasing SM counts in adults 18-37 years old with highest level of SM.

    The beneficial effects of probiotics are now widely reported, although there are only a few studies on their anti-aging effects. We have found that Lactobacillus plantarum HY7714 (HY7714) improves skin hydration and has anti-photoaging effects, and in the present study, we have further evaluated the anti-aging effect of HY7714 via a randomized, double blind, placebo-controlled clinical trial. The trial included 110 volunteers aged 41 and 59 years who have dry skin and wrinkles. Participants took 1 × 10(10) CFU/day of HY7714 (probiotic group) or a placebo (placebo group) for 12 weeks. Skin hydration, wrinkles, skin gloss, and skin elasticity were measured every 4 weeks during the study period. There were significant increases in the skin water content in the face (p < 0.01) and hands (p < 0.05) at week 12 in the probiotic group. Transepidermal water loss decreased significantly in both groups at weeks 4, 8, and 12 (p < 0.001 compared with baseline), and was suppressed to a greater extent in the face and forearm in the probiotic group at week 12. Volunteers in the probiotic group had a significant reduction in wrinkle depth at week 12, and skin gloss was also significantly improved by week 12. Finally, skin elasticity in the probiotic group improved by 13.17% (p < 0.05 vs. controls) after 4 weeks and by 21.73% (p < 0.01 vs. controls) after 12 weeks. These findings are preliminary confirmation of the anti-aging benefit to the skin of L. plantarum HY7714 as a nutricosmetic agent.

    Full Text Available Background: The third common urinary tract disease was renal stone, after the UTI and pathologic states of kidney. TUL is most useful and effective for removing the stones of inferior ureter. In other hand aminophylline can decrease urinary tract spasm. Then, combination of TUL and aminophylline help us to reduce the complication of TUL. Methods and materials: We have study on 87 case of renal colic who referred to Imam Khomeini hospital of sari and Tooba clinic. This study was a double blind systematic randomized clinical trial that patients were divided to two group as 1 and 2: group one includes patients who received aminophylline and group 2 were selected as our control samples. Our sample size was calculated by statistic analysis according to recent studies. Result: The average of TUL time was 5.12± 1.77 min in group 1 and 6.59± 3.47 min in group 2(p0.05. ESWL was used in one patient of group 1 because of remaining of stone, but 7 patients of group 2 did not response to Transureter lithotripsy, then they needed ESWL. Complication were not seen in patient who received Aminophylline and mean arterial pressure and heart rate was equal in two group. Conclusion: The difference of TUL Time between two groups was meaningful. As you know, aminophylline has an antispasmotic effect on urinary tract and tract with smooth muscle, and according to our finding, usage of aminophylline can reduce the complication of TUL and increase success rate of Lithotripsy in this patient. In other hand, it complications was few.

    Retinal detachment surgery is frequently associated with significant postoperative pain and emesis in adults. In this randomized, double-blind, controlled study we sought to demonstrate that 1% ropivacaine peribulbar (PB) block in conjunction with general anesthesia (GA) improves operative conditions and postoperative analgesia compared with GA combined with subcutaneous normal saline injection into the inferior eyelid. Thirty-one patients were included in each group. Anesthesia was performed with target-controlled infusion propofol and continuous remifentanil infusion adjusted to maintain bispectral index values between 40 and 50. Postoperative analgesia included fixed-dose IV infusion of propacetamol and IV injection of nefopam via a patient-controlled analgesia device. Tramadol was infused IV as rescue medication. Demographic data were comparable between the groups and bispectral index values were maintained at the objective target. In the PB group, fewer patients presented an oculocardiac reflex (6 versus 17; P < 0.01); bleeding interfering with the surgical field was reduced (1 versus 11 patients; P < 0.01); mean time to first nefopam request was longer (148 +/- 99 versus 46 +/- 58 min; P < 0.01); mean nefopam consumption was diminished during the first 6 h after tracheal extubation (18.9 +/- 13.9 versus 28.5 +/- 14.7 mg; P < 0.05); immediate postoperative pain scores were lower; and fewer patients required rescue medication (5 versus 23; P < 0.01). The two groups were similar with respect to the incidence of postoperative nausea and vomiting. Overall, PB block combined with GA improved operating conditions and postoperative analgesia in retinal detachment surgery. PMID:16551903

    Intermetatarsal neuroma or Morton's neuroma is a painful condition of the foot resulting from an entrapment of the common digital nerve typically in the third intermetatarsal space. The pain can be severe and especially problematic with walking. Treatment options are limited and surgery may lead to permanent numbness in the toes. Capsaicin, the pungent ingredient of hot peppers, produces analgesia by inducing retraction of nociceptive afferents from the area of innervation and is effective in treating certain neuropathic pain disorders. A randomized double-blind placebo-controlled study was conducted to test the efficacy, tolerability, and safety of a single 0.1 mg dose of capsaicin vs placebo injected into the region of the neuroma. A total of 58 subjects diagnosed with Morton's neuroma with foot pain ≥4 (0-10 numerical pain rating scale) were injected with 2 mL of lidocaine into the intermetatarsal space proximal to the neuroma to provide local anesthesia. After 5 minutes, 0.1 mg capsaicin or placebo was injected into the intermetatarsal space containing the painful neuroma. Average foot pain was rated for 2 weeks before through 4 weeks after injection. At weeks 1 and 4, the decrease in pain was significantly greater in the subjects treated with capsaicin (P = 0.021 and P = 0.019, respectively). A trend toward significance was noted at weeks 2 and 3. Improvements in functional interference scores and reductions in oral analgesic use were also seen in the capsaicin-treated group. These findings suggest that injection of capsaicin is an efficacious treatment option for patients with painful intermetatarsal neuroma. PMID:26963851

    Full Text Available Context Glutamine is the main source of energy of the enterocyte and diarrhea and weight loss are frequent in HIV infected patients. Objective To determine the effect of alanyl-glutamine supplementation on intestinal permeability and absorption in these patients. Methods Randomized double-blinded, placebo-controlled study using isonitrogenous doses of alanyl-glutamine (24 g/day and placebo (glycine, 25 g/day during 10 days. Before and after this nutritional supplementation lactulose and mannitol urinary excretion were determined by high performance liquid chromatography. Results Forty six patients with HIV/AIDS, 36 of whom were male, with 37.28 ± 3 (mean ± standard error years were enrolled. Twenty two and 24 subjects were treated with alanyl-glutamine and with glycine respectively. In nine patients among all in the study protocol that reported diarrhea in the 14 days preceding the beginning of the study, mannitol urinary excretion was significantly lower than patients who did not report this symptom [median (range: 10.51 (3.01–19.75 vs. 15.37 (3.93–46.73; P = 0.0281] and lactulose/mannitol ratio was significantly higher [median (range: 0.04 (0.00–2.89 vs. 0.02 (0.00–0.19; P = 0.0317]. There was also a significant increase in mannitol urinary excretion in the group treated with alanyl-glutamine [median (range: 14.38 (8.25–23.98 before vs 21.24 (6.27–32.99 after treatment; n = 14, P = 0.0382]. Conclusion Our results suggest that the integrity and intestinal absorption are more intensely affected in patients with HIV/AIDS who recently have had diarrhea. Additionally, nutritional supplementation with alanyl-glutamine was associated with an improvement in intestinal absorption.

    Deficits in social cognition, including emotional processing, are hallmarks of schizophrenia and antipsychotic agents seem to be ineffectual to improve these symptoms. However, oxytocin does seem to have beneficial effects on social cognition. The aim of this study was to examine the effects of four months of treatment with intranasal oxytocin, in 31 patients with schizophrenia, on distinct aspects of social cognition. This was assessed using standardized and experimental tests in a randomized, double-blind, placebo-controlled, cross-over trial. All patients underwent clinical and experimental assessment before treatment, four months after treatment and at the end of treatment. Social cognition abilities were assessed with the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT) and the Reading the Mind in the Eyes task (RMET). Furthermore, an Emotional Priming Paradigm (EPP) was developed to examine the effects of oxytocin on implicit perceptual sensitivity to affective information and explicit facial affect recognition. We found that oxytocin improved performance on MSCEIT compared to placebo in Branch 3-Understanding Emotion (p-value=0.004; Cohen׳s d=1.12). In the EPP task, we observed a significant reduction of reaction times for facial affect recognition (p-value=0.021; Cohen׳s d=0.88). No effects were found for implicit priming or for theory of mind abilities. Further study is required in order to highlight the potential for possible integration of oxytocin with antipsychotic agents as well as to evaluate psycho-social treatment as a multi-dimensional approach to increase explicit emotional processing abilities and compensate social cognition deficits related to schizophrenia.

    Full Text Available  Objective: "n "nAttention-Deficit/Hyperactivity Disorder (ADHD is one of the most common mental disorders in childhood and it continues to adulthood without proper treatment. Stimulants have been used in treatment of ADHD for many years and the efficacy of methylphenidate (MPH in the treatment of adults with ADHD has been proven to be acceptable according to meta-analysis studies. However, there are some concerns about stimulants. Finding other effective medications for the treatment of adult ADHD seems necessary. We tried a monoamine oxidase inhibitor, Selegiline, as there are some theoretical and experimental evidences for the efficacy of this medication . "nMethod: Forty patients were randomized to receive Selegiline or methylphenidate in an equal ratio for an 8-week double-blind clinical trial. Each patient filled the CAARS self report screening form before starting to take the medication and in weeks 2-4-6 and 8. Patients were also assessed by a psychiatrist at the baseline and on each 14 days up to the 8 weeks period. "nResults: The mean score of the two groups- receiving Selegiline or methylphenidate- decreased over the 8 weeks. There was not a significant difference between the two groups. The most prevalent side-effect of methylphenidate was decrease of appetite and for Selegiline change in sleep pattern . "nConclusion: Selegiline is as effective as methylphenidate in the treatment of adults with Attention-Deficit/Hyperactivity Disorder. Selegiline can be an alternative medication for the treatment of adult ADHD If its clinical efficacy is proven by other larger studies .

    Full Text Available Introduction. L-Acetylcarnitine (LAC, the acetyl ester of carnitine naturally present in the central nervous system and involved in several neural pathways, has been demonstrated to be active in various animal experimental models resembling some features of human depression. The aim of the study is to verify whether LAC can have an antidepressant action in a population of elderly patients with dysthymic disorder in comparison with a traditional antidepressant such as fluoxetine.Methods. Multicentric, double-blind, double-dummy, controlled, randomized study based on a observation period of 7 weeks. 80 patients with DSM-IV diagnosis of dysthymic disorder were enrolled in the study and subdivided into 2 groups. Group A patients received LAC plus placebo; group B patients received fluoxetine 20 mg/die plus placebo. Clinical assessment was performed through several psychometric scales at 6 different moments.Results. Group A patients showed a statistically significant improvement in the following scales: HAM-D, HAM-A, BDI and Touluse–Pieron Test. Comparison between the two groups, A and B, generally showed very similar clinical progression.Discussion. The results obtained with LAC and fluoxetine were equivalent. As the subjects in this study were of senile age, it is possible to hypothesize that the LAC positive effect on mood could be associated with improvement in subjective cognitive symptomatology. The difference in the latency time of clinical response (1 week of LAC treatment, compared with the 2 weeks' latency time with fluoxetine suggests the existence of different mechanisms of action possibly in relation to the activation of rapid support processes of neuronal activity.

    AIM: To study the therapeutic efficacy of a Chinese and Western integrated regimen, killing Helicobacter pylori quadruple therapy on H pylori-associated peptic ulcers(PU).METHODS: With prospective and double-blind controlled method, seventy-five active PU patients with H pylori infection were randomized to receive one of the following three regimens: (1) new triple therapy (group A:lansoprazole 30 mg qd, plus clarithromycin 250 mg bid,plus amoxycillin 500 mg tid, each for 10 d); (2) killing Hp quadruple therapy(group B: the three above drugs plus killing H pylori capsule 6 capsules bid for 4 wk) and (3)placebo(group C: gastropine 3 tablets bid for 4 wk).H pylori eradication and ulcer healing quality were evaluated under an endoscope 4 wk after treatment. The patients were followed up for 5 years.RESULTS: Both the healing rate of PU and H pylori eradication rate in group B were significantly higher than those in group C (100% and 96.4% vs 20% and 0%,respectively, P<0.005), but there was no significant difference compared to those in group A (88% and92%, P>0.05). The healing quality of ulcer in group B was superior to that in groups C and A (P<0.05). The recurrence rate of PU in group B (4%) was lower than that in group A (10%) and group C (100%, P<0.01).CONCLUSION: Killing Helicobacter pylori quadruple therapy can not only promote the eradication of H pylori and healing quality of ulcer but also reduce recurrence rate of ulcer.

    Full Text Available Smokers have increased susceptibility and altered innate host defense responses to influenza virus infection. Broccoli sprouts are a source of the Nrf2 activating agentsulforaphane, and short term ingestion of broccoli sprout homogenates (BSH has been shown to reduce nasal inflammatory responses to oxidant pollutants.Assess the effects of BSH on nasal cytokines, virus replication, and Nrf2-dependent enzyme expression in smokers and nonsmokers.We conducted a randomized, double-blind, placebo-controlled trial comparing the effects of BSH on serially sampled nasal lavage fluid (NLF cytokines, viral sequence quantity, and Nrf2-dependent enzyme expression in NLF cells and biopsied epithelium. Healthy young adult smokers and nonsmokers ingested BSH or placebo (alfalfa sprout homogenate for 4 days, designated Days -1, 0, 1, 2. On Day 0 they received standard vaccine dose of live attenuated influenza virus (LAIV intranasally. Nasal lavage fluids and nasal biopsies were collected serially to assess response to LAIV.In area under curve analyses, post-LAIV IL-6 responses (P = 0.03 and influenza sequences (P = 0.01 were significantly reduced in NLF from BSH-treated smokers, whilequinoneoxidoreductasein NLF cells was significantly increased. In nonsmokers, a similar trend for reduction in virus quantity with BSH did not reach statistical significance.In smokers, short term ingestion of broccoli sprout homogenates appears to significantly reduce some virus-induced markers of inflammation, as well as reducing virus quantity. Nutritional antioxidant interventions have promise as a safe, low-cost strategy for reducing influenza risk among smokers and other at risk populations.ClinicalTrials.gov NCT01269723.

  14. A double-blind, prospective, randomized, multicenter group comparison study of iopromide 240 vs iohexol 240 in myelography

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate the safety and efficacy of iopromide 240 mgI/ml in comparison with iohexol 240 mgI/ml in myelography. A total of 421 patients in seven centers and four countries received an average of 11.9 ml of either iopromide 240 (278 patients) or iohexol 240 (143 patients) for X-ray and/or CT myelography in a randomized (2:1), prospective, double-blind study. All patients were followed up 3-4 h after the procedure, and 327 patients remained hospitalized for 24 h. In 82 patients an EEG was recorded prior to as well as 3-4 h and 24 h after myelography. Physical examinations, including measurement of vital signs, were performed in all patients at these time points. The results were subject to statistical analysis with the primary variable being the incidence of adverse events. Both contrast media (CM) were equally effective in terms of opacification. The rating for opacity was ''good'' or ''excellent'' in 88 % for both CM. Four patients (iopromide group: n = 3; iohexol group: n = 1) had transient EEG changes but did not show clinical symptomatology. The overall rate of patients experiencing any adverse event (AE) was 16.9 % for iopromide 240 and 14.0 % for iohexol 240. Equivalence testing was inconclusive; however, the results indicated equivalence. The rate for AEs considered as study-drug related was slightly lower with iopromide 240 than with iohexol 240 (7.2 vs 7.7 %, respectively). Neither unknown nor unexpected AEs known for myelographic X-ray CM nor serious adverse events were observed. Iopromide 240 and iohexol 240 are equally safe and effective and can be recommended for myelography. (orig.)

    BACKGROUND: Renal denervation (RDN), treating resistant hypertension, has, in open trial design, been shown to lower blood pressure (BP) dramatically, but this was primarily with respect to office BP. METHOD: We conducted a SHAM-controlled, double-blind, randomized, single-center trial to establish.......5 (SHAM)].RDN performed at a single center and by a high-volume operator reduced ABPM to the same level as SHAM treatment and thus confirms the result of the HTN3 trial. CONCLUSION: Further, clinical use of RDN for treatment of resistant hypertension should await positive results from double-blinded, SHAM...... cannot be changed in any way or used commercially. http://creativecommons.org/licenses/by-nc-nd/4.0....

  18. Eicosapentaenoic acid (EPA) efficacy for colorectal aberrant crypt foci (ACF): a double-blind randomized controlled trial

    International Nuclear Information System (INIS)

    Colorectal cancer (CRC) is one of the most commonly occurring neoplasms and a leading cause of cancer death worldwide, and new preventive strategies are needed to lower the burden of this disease. Eicosapentaenoic acid (EPA), the omega-3 polyunsaturated fatty acid that is widely used in the treatment of hyperlipidemia and prevention of cardiovascular disease, has recently been suggested to have a suppressive effect on tumorigenesis and cancer cell growth. In CRC chemoprevention trials, in general, the incidence of polyps or of the cancer itself is set as the study endpoint. Although the incidence rate of CRC would be the most reliable endpoint, use of this endpoint would be unsuitable for chemoprevention trials, because of the relatively low occurrence rate of CRC in the general population and the long-term observation period that it would necessitate. Moreover, there is an ethical problem in conducting long-term trials to determine whether a test drug might be effective or harmful. Aberrant crypt foci (ACF), defined as lesions containing crypts that are larger in diameter and stain more darkly with methylene blue than normal crypts, are considered as a reliable surrogate biomarker of CRC. Thus, we devised a prospective randomized controlled trial as a preliminary study prior to a CRC chemoprevention trial to evaluate the chemopreventive effect of EPA against colorectal ACF formation and the safety of this drug, in patients scheduled for polypectomy. This study is a multicenter, double-blind, placebo-controlled, randomized controlled trial to be conducted in patients with both colorectal ACF and colorectal polyps scheduled for polypectomy. Eligible patients shall be recruited for the study and the number of ACF in the rectum counted at the baseline colonoscopy. Then, the participants shall be allocated randomly to either one of two groups, the EPA group and the placebo group. Patients in the EPA group shall receive oral 900-mg EPA capsules thrice daily (total daily

    Objective To evaluate the effectiveness of a xylitol pediatric topical oral syrup to reduce the incidence of dental caries of very young children. Design Randomized, double-blinded, controlled trial. Setting Communities in the Republic of the Marshall Islands. Participants 108 children aged 9 to 15 months were screened and 100 were enrolled. Intervention Children were randomized and parents administered topical oral xylitol syrup two times (Xyl-2X, two xylitol 4.00 g/dose + one sorbitol dose) or three times (Xyl-3X, three xylitol 2.67 g/dose) per day (total 8 g) or control (one xylitol 2.67 g/dose + two sorbitol dose). Outcome Measures The outcome end-point of the study was the number of decayed primary teeth. Results Ninety-four of 100 children (mean±SD age, 15.0±2.7 months at randomization) with at least one follow-up exam were included in the intent-to-treat analysis. The mean±SD follow-up period was 10.5±2.2 months. Nearly 52% of children in the control condition had tooth decay compared to 40.6% among Xyl-3X and 24.2% among Xyl-2X conditions. The mean±SD number of decayed teeth was 1.9±2.4 for control, 1.0±1.4 for Xyl-3X, and 0.6±1.1 for Xyl-2X condition. Compared to controls, there was significantly fewer decayed teeth in the Xyl-2X (relative risk [RR], 0.30; 95% confidence interval [CI] 0.13, 0.66; P=.003) and Xyl-3X (RR, 0.50; 95% CI 0.26, 0.96; P=0.037) conditions. There was no statistical difference between the two xylitol treatment conditions (P=0.22). Conclusion Oral xylitol syrup administered topically two or three times each day at a total dose of 8 g was effective in preventing Early Childhood Caries. PMID:19581542

    Full Text Available Aim: To investigate whether 1-step titration of the rivastigmine patch (initiated at 5 cm2 and titrated to 10 cm2 after 4 weeks is well tolerated in Japanese patients with Alzheimer's disease (AD as compared to 3-step titration (initiated at 2.5 cm2 and titrated by 2.5 cm2 every 4 weeks to 10 cm2. Methods: A 24-week, multicenter, randomized, double-blind study was conducted in Japan between July 2012 and May 2014. Patients with mild to moderate AD aged 50-85 years were randomized 1:1 to 1-step or 3-step titration of the rivastigmine once-daily patch. The primary endpoint was the proportion of patients with adverse events leading to discontinuation. Results: Of 216 patients randomized, 215 (1-step, n = 107; 3-step, n = 108 were included in the safety analysis. The primary endpoint outcome was 15.0% in the 1-step group and 18.5% in the 3-step group. The observed treatment difference was −3.6% (95% confidence interval: −17.0, 9.6, falling within the prespecified acceptance range. Conclusion: The tolerability of two different titration schemes was similar in Japanese patients with AD.

    We compared the short-term efficacy of rigid versus soft lateral wedge arch support (LWAS) insoles for patients with knee osteoarthritis (OA), as assessed using the International Classification of Functioning, Disability and Health (ICF) system, through a prospective, double-blind, randomized controlled trial.Participants who fulfilled the combined radiographic and clinical criteria for knee OA, as defined by the American College of Rheumatology, were randomly prescribed 1 pair of rigid or soft LWAS insoles. Body functions and structures were evaluated according to Kellgren-Lawrence scores, the Foot Posture Index, Hospital Anxiety and Depression Scale scores, the pain-pressure threshold, postural stability, dynamic balance, and fall risk; activities and participation were assessed according to 10-m fast speed walking, stair climbing and chair rising times, and Chronic Pain Grade questionnaire responses; and knee OA-related health status was evaluated using the Knee Injury and Osteoarthritis Outcome Score (KOOS). Hospital Anxiety and Depression Scale scores, the pain-pressure threshold, physical activity, balance, Chronic Pain Grade questionnaire responses, and the KOOS were recorded before treatment and at 1-, 2-, and 3-month follow-ups.We enrolled 90 participants, 70 women and 20 men, with mean ages of 60.6 ± 10.8 and 63.1 ± 10.8 years in the rigid and soft LWAS insole groups, respectively. Repeated-measures analysis of covariance revealed significant time × group effect improvements in pain (P = 0.008 for the KOOS), stair ascent time (P = 0.003), daily living function (P = 0.003 for the KOOS), sports and recreation function (P = 0.012 for the KOOS), and quality of life (P = 0.021 for the KOOS) in the soft LWAS insole group.Patients with knee OA who used soft LWAS insoles for a short term showed more significant improvement than did those who used rigid LWAS insoles in pain, physical activity, daily living function, sports and recreation function

    Cadazolid, a novel fluoroquinolone-oxazolidinone antibiotic, exhibits potent in vitro activity against Clostridium difficile, including the epidemic BI/NAP1/027 strain. This multicenter, randomized, double-blind, active reference group, phase 2 study evaluated the efficacy and safety of oral cadazolid in treatment of adult patients with C. difficile infection (CDI). Eligible patients with first occurrence/first recurrence of CDI were randomized 1:1:1:1 to 250, 500, or 1,000 mg cadazolid twice daily (BID) or oral 125 mg vancomycin four times daily (QID) for 10 days. The primary endpoint was clinical cure at test of cure (48 ± 24 h after the end of treatment; modified intent-to-treat population), defined as resolution of diarrhea with no further CDI treatment required. Secondary endpoints included recurrence rate, sustained clinical response (clinical cure without recurrence), and time to diarrhea resolution. Of 84 patients enrolled, 20, 22, 20, and 22 received 250, 500, or 1,000 mg cadazolid BID or 125 mg vancomycin QID, respectively. The primary endpoint was achieved in 76.5% (80% confidence interval [CI], 58.4, 89.3), 80.0% (63.9, 91.0), 68.4% (51.1, 82.5), and 68.2% (52.3, 81.3) of patients, respectively. There was no evidence of a cadazolid dosage-dependent response. Each dosage of cadazolid resulted in a lower recurrence rate than with vancomycin (18.2 to 25.0% versus 50%). Consequently, higher sustained clinical response rates were observed with cadazolid (46.7 to 60.0%) than with vancomycin (33.3%). The times to diarrhea resolution were similar for cadazolid and vancomycin. Cadazolid was well tolerated, with no safety signal observed. The results of this phase 2 study support further clinical development of cadazolid. (This study has been registered in the United States at ClinicalTrials.gov under registration no. NCT01222702 and in Europe with the European Medicines Agency under registration no. EUDRA-CT 2010-020941-29.).

Objective: To assess the clinical efficacy of a complex integral anti-cellulite gel. Methods: This double-blind, randomized, placebo-controlled study involved 44 healthy women, aged 25–55 years. Subjects had a normal to slightly overweight body mass index and presented slight to moderate cellulite on their thighs, buttocks, and/or hips at baseline. Subjects were randomly assigned to either the treated or placebo group and accordingly applied the active product or placebo on their hips, stomach, buttocks, and thighs, twice daily for 3 months. Skin tonicity, orange-peel aspect, and stubborn cellulite were assessed at day 0, 28, 56, and 84. A self-evaluation questionnaire was completed by all volunteers. Results: At the end of the study, an average of 81% of the subjects applying the active product presented improvement in their cellulite condition versus 32% for the placebo group (all descriptors and sites combined. At day 84, skin tonicity, orange-peel appearance, and stubborn cellulite were improved in a significant manner (P<0.05 over placebo, on all studied areas. Skin tonicity improved on average by +41% for buttocks, +35% for hips, and +31% for thighs. Orange peel appearance was reduced on average by -25% for buttocks, -22% for hips, and -22% for thighs. Stubborn cellulite was reduced on average by -19% for buttocks, -24% for hips, and -22% for thighs. Circumference measurements decreased in a significant manner (P<0.05 over placebo

    Full Text Available BACKGROUND: Pulmonary cachexia is common in advanced chronic obstructive pulmonary disease (COPD, culminating in exercise intolerance and a poor prognosis. Ghrelin is a novel growth hormone (GH-releasing peptide with GH-independent effects. The efficacy and safety of adding ghrelin to pulmonary rehabilitation (PR in cachectic COPD patients were investigated. METHODOLOGY/PRINCIPAL FINDINGS: In a multicenter, randomized, double-blind, placebo-controlled trial, 33 cachectic COPD patients were randomly assigned PR with intravenous ghrelin (2 µg/kg or placebo twice daily for 3 weeks in hospital. The primary outcomes were changes in 6-min walk distance (6-MWD and the St. George Respiratory Questionnaire (SGRQ score. Secondary outcomes included changes in the Medical Research Council (MRC scale, and respiratory muscle strength. At pre-treatment, serum GH levels were increased from baseline levels by a single dose of ghrelin (mean change, +46.5 ng/ml; between-group p<0.0001, the effect of which continued during the 3-week treatment. In the ghrelin group, the mean change from pre-treatment in 6-MWD was improved at Week 3 (+40 m, within-group p = 0.033 and was maintained at Week 7 (+47 m, within-group p = 0.017, although the difference between ghrelin and placebo was not significant. At Week 7, the mean changes in SGRQ symptoms (between-group p = 0.026, in MRC (between-group p = 0.030, and in maximal expiratory pressure (MEP; between-group p = 0.015 were better in the ghrelin group than in the placebo group. Additionally, repeated-measures analysis of variance (ANOVA indicated significant time course effects of ghrelin versus placebo in SGRQ symptoms (p = 0.049 and MEP (p = 0.021. Ghrelin treatment was well tolerated. CONCLUSIONS/SIGNIFICANCE: In cachectic COPD patients, with the safety profile, ghrelin administration provided improvements in symptoms and respiratory strength, despite the lack of a significant between

    Full Text Available We conducted a randomized, double-blind, placebo-controlled, crossover study at a single center in South Africa, to ascertain whether amitriptyline is an effective analgesic for painful HIV-associated sensory neuropathy of moderate to severe intensity in: i antiretroviral drug naive individuals, and ii antiretroviral drug users. 124 HIV-infected participants (antiretroviral drug naive = 62, antiretroviral drug users = 62 who met the study criteria for painful HIV-associated sensory neuropathy were randomized to once-daily oral amitriptyline (titrated to a median: interquartile range of 50: 25-50 mg or placebo for six weeks, followed by a three-week washout period and subsequent treatment crossover. The primary outcome measure was change from baseline in worst pain intensity of the feet (measured by participant self-report using an 11-point numerical pain rating scale after six weeks of treatment. 122 of 124 participants completed all study visits and were included in the analysis of the primary outcome. In the antiretroviral drug-naive group (n = 61 there was no significant difference in the mean change in pain score from baseline after six weeks of treatment with placebo or amitriptyline [amitriptyline: 2.8 (SD 3.3 vs. placebo: 2.8 (3.4]. Similarly, there was no significant difference in the change in pain score after six weeks of treatment with placebo or amitriptyline in the antiretroviral drug-user group (n = 61 [amitriptyline: 2.7 (3.3 vs. placebo: 2.1 (2.8]. Controlling for period effects and treatment order effects did not alter the outcome of the analyses. Nor did analyzing the intention-to-treat cohort (missing data interpolated using baseline observation carried forward alter the outcome of the analyses. In summary, amitriptyline, at the doses used here, was no more effective than an inactive placebo at reducing pain intensity in individuals with painful HIV-associated sensory neuropathy of moderate to severe intensity, irrespective of

    Objective To evaluate the efficacy and safety of oseltamivir phosphate as treatment for naturally acquired influenza infection. Methods This study was conducted as a double-blind, randomized, placebo-controlled, multicenter trial during the influenza epidemic season from January to April 2001 at 7 centers in China. A total of 478 adults without other medical history, aged 18 to 65 years, were enrolled into the study. All subjects demonstrated febrile respiratory illness of no more than 36 hours' duration with a temperature of 37.8℃ or more plus at least two of the following symptoms: coryza/nasal congestion, sore throat, cough, myalgia/muscles aches and pain, fatigue, headache or chills/sweats. Individuals were randomized into either the oseltamivir phosphate or placebo group with identical-looking capsules. Either oral oseltamivir phosphate, 75 mg twice daily, or placebo was administered to the subjects for 5 days.Results A total of 451 individuals were analyzed for efficacy as the intent-to-treat population (ITT) (216 oseltamivir and 235 placebo) and 273 individuals were identified as influenza-infected through laboratory test, who were then defined as the intent-to-treat infected population (ITTI) (134 oseltamivir and 139 placebo). Four hundred and fifty nine individuals were included in the safety analysis. In the ITTI population, the cumulative alleviation proportion of oseltamivir group was significantly higher than that of the placebo group (P=0.0466)). The median duration of illness was 91.6 h [95% confidence interval (CI)=80.2-101.3 h] in the oseltamivir group and 95 h (95% CI=84.5-105.3 h) in the placebo group. The median area under the curve of decreased total score was significantly higher in the oseltamivir group than in the placebo group, 1382.9 and 1236.7 score-hours, respectively (P=0.0196). For the ITT population, similar results were observed. Adverse events (AE) were similarly reported in both the oseltamivir group and the placebo group. The

    Background Acute gout is an intensely painful,inflammatory arthritis.Although the non-steroidal anti-inflammatory drugs (NSAIDs) are widely used for this condition,the efficacy is based on only a few studies,particularly in China.We tried to assess the safety and efficacy of etoricoxib in the treatment of acute gouty arthritis in China.Methods A randomized,double-blind,active comparator study was conducted at 10 sites in China.Patients (n=178; ≥18 years of age) with acute gouty attack (<48 hours) were treated for 5 days with etoricoxib (120 mg/d; n=89) or indometacin (75 mg twice daily; n=89).The primary efficacy end point was self-assessed pain in the affected joint (0-4 point Likert scale) from days 2-5.Secondary end points included investigator assessments of tenderness and swelling,patient/ investigator global assessments of response to therapy,and patients discontinuing treatment.Safety was assessed by adverse events (AEs).Results Etoricoxib and indometacin had comparable primary and secondary end points.Mean change difference from baseline from days 2-5 was 0.03 (95% confidence interval (Cl)-0.19 to 0.25; P=0.6364),which fell within the prespecified comparative bounds of-0.5 to 0.5.No severe AEs were associated with etoricoxib use.Non-severe AEs were mainly digestive and general,and most (73.7%) were mild,although they caused withdrawal of two subjects in the etoricoxib group,due to bilateral renal calculi and uronephrosis of the left kidney (unrelated to etoricoxib) and fever and chills (potentially etoricoxib-related).Overall,AEs were similar,although the absolute number of AEs in the etoricoxib group (n=31) was less than the indometacin group (n=34).Conclusions Etoricoxib (120 mg once daily) is effective in treating acute gout,is generally safe and well-tolerated,and is comparable in efficacy to indometacin (75 mg twice daily).

    Full Text Available Introduction: Bioequivalence or compared equivalence studies are used to demonstrate claims that the new product, named generic product, will have the same bioavailability as the reference product, named brand product. If two products are bioequivalent it means that they would expect to have the same efficacy and security. Bioequivalence is established by the statistical estimation of significant differences or not in the pharmacokinetics parameters of area under the curve (AUC and maximum concentration (Cmax. In this case, bioequivalence will be evaluated and the bioavailability of Valsartan will be compared. Valsartan is an agent antihypertensive and specific angiotensin II antagonist acting on the AT1 receptor subtype. Objective: The aim of this study was to evaluate the bioequivalence of two pharmaceutical products whose active principle is Valsartan, based on the comparison of the pharmacokinetic measures of rate and extent (in terms of required time in which valsartan reaches the sanguineous circulation after a oral dose to 15 volunteers. Metodology: This was a randomized crossover double blind single-dose study on 15 male healthy volunteers aged between 19 and 28 years. The study was performed in two periods. Each treatment period consisted of a single-dose of 320 mg valsartan, with a wash-out time of 8 days between the first and second period. Plasma concentrations of valsartan were evaluated by HPLC/UV with method of addition of valsartan standard and losartan as internal standard. Results: Valsartan tablets formulation showed this pharmacokinetic parameters: AUC 44,893 µg/mlxh, Cmax 6,430.3 µg/ml and Tmax 2 h. Valsartan capsules formulation showed this pharmacokinetic parameters: AUC 44,963 µg/mlxh, Cmax 5,831.4 µg/ml and Tmax 2.5 h. Conclusion: The study showed no statistically significant differences in the plasma concentration levels after administration of the two formulations of valsartan: 80 mg tablets and 80 mg capsules.

    Gijs H Goossens

    Full Text Available BACKGROUND: Blockade of the renin-angiotensin system (RAS reduces the incidence of type 2 diabetes mellitus. In rodents, it has been demonstrated that RAS blockade improved adipose tissue (AT function and glucose homeostasis. However, the effects of long-term RAS blockade on AT function have not been investigated in humans. Therefore, we examined whether 26-wks treatment with the angiotensin II type 1 receptor blocker valsartan affects AT function in humans with impaired glucose metabolism (IGM. METHODOLOGY/PRINCIPAL FINDINGS: We performed a randomized, double-blind, placebo-controlled parallel-group study, in which 38 subjects with IGM were treated with valsartan (VAL, 320 mg/d or placebo (PLB for 26 weeks. Before and after treatment, an abdominal subcutaneous AT biopsy was collected for measurement of adipocyte size and AT gene/protein expression of angiogenesis/capillarization, adipogenesis, lipolytic and inflammatory cell markers. Furthermore, we evaluated fasting and postprandial AT blood flow (ATBF ((133Xe wash-out, systemic inflammation and insulin sensitivity (hyperinsulinemic-euglycemic clamp. VAL treatment markedly reduced adipocyte size (P<0.001, with a shift toward a higher proportion of small adipocytes. In addition, fasting (P = 0.043 and postprandial ATBF (P = 0.049 were increased, whereas gene expression of angiogenesis/capillarization, adipogenesis and macrophage infiltration markers in AT was significantly decreased after VAL compared with PLB treatment. Interestingly, the change in adipocyte size was associated with alterations in insulin sensitivity and reduced AT gene expression of macrophage infiltration markers. VAL did not alter plasma monocyte-chemoattractant protein (MCP-1, TNF-α, adiponectin and leptin concentrations. CONCLUSIONS/SIGNIFICANCE: 26-wks VAL treatment markedly reduced abdominal subcutaneous adipocyte size and AT macrophage infiltration markers, and increased ATBF in IGM subjects. The VAL

    Full Text Available BACKGROUND AND OBJECTIVES: A review of all the adjuncts for intravenous regional anaesthesia concluded that there is good evidence to recommend NonSteroidal Anti-Inflammatory agents and pethidine in the dose of 30 mg dose as adjuncts to intravenous regional anaesthesia. But there are no studies to compare pethidine of 30 mg dose to any of the NonSteroidal Anti-Inflammatory agents. METHODS: In a prospective, randomized, double blind study, 45 patients were given intravenous regional anaesthesia with either lignocaine alone or lignocaine with pethidine 30 mg or lignocaine with ketprofen 100 mg. Fentanyl was used as rescue analgesic during surgery. For the first 6 h of postoperative period analgesia was provided by fentanyl injection and between 6 and 24 h analgesia was provided by diclofenac tablets. Visual analogue scores for pain and consumption of fentanyl and diclofenac were compared. RESULTS: The block was inadequate for one case each in lignocaine group and pethidine group, so general anaesthesia was provided. Time for the first dose of fentanyl required for postoperative analgesia was significantly more in pethidine and ketoprofen groups compared to lignocaine group (156.7 ± 148.8 and 153.0 ± 106.0 vs. 52.1 ± 52.4 min respectively. Total fentanyl consumption in first 6 h of postoperative period was less in pethidine and ketoprofen groups compared to lignocaine group (37.5 ± 29.0 mcg, 38.3 ± 20.8 mcg vs. 64.2 ± 27.2 mcg respectively. Consumption of diclofenac tablets was 2.4 ± 0.7, 2.5 ± 0.5 and 2.0 ± 0.7 in the control, pethidine and ketoprofen group respectively, which was statistically not significant. Side effects were not significantly different between the groups. CONCLUSION: Both pethidine and ketoprofen are equally effective in providing postoperative analgesia up to 6 h, without significant difference in the side effects and none of the adjuncts provide significant analgesia after 6 h.

    Full Text Available Atypical antipsychotics exhibit metabolic side effects including diabetes mellitus and obesity. The adverse events are preceded by acute worsening of oral glucose tolerance (oGTT along with reduced plasma free fatty acids (FFA and leptin in animal models. It is unclear whether the same acute effects occur in humans.A double blind, randomized, placebo-controlled crossover trial was conducted to examine the potential metabolic effects of olanzapine in healthy volunteers. Participants included male (8 and female (7 subjects [18-30 years old, BMI 18.5-25]. Subjects received placebo or olanzapine (10 mg/day for three days prior to oGTT testing. Primary endpoints included measurement of plasma leptin, oral glucose tolerance, and plasma free fatty acids (FFA. Secondary metabolic endpoints included: triglycerides, total cholesterol, high- and low-density lipoprotein cholesterol, heart rate, blood pressure, body weight and BMI. Olanzapine increased glucose Area Under the Curve (AUC by 42% (2808±474 vs. 3984±444 mg/dl·min; P = 0.0105 during an oGTT. Fasting plasma leptin and triglycerides were elevated 24% (Leptin: 6.8±1.3 vs. 8.4±1.7 ng/ml; P = 0.0203 and 22% (Triglycerides: 88.9±10.1 vs. 108.2±11.6 mg/dl; P = 0.0170, whereas FFA and HDL declined by 32% (FFA: 0.38±0.06 vs. 0.26±0.04 mM; P = 0.0166 and 11% (54.2±4.7 vs. 48.9±4.3 mg/dl; P = 0.0184, respectively after olanzapine. Other measures were unchanged.Olanzapine exerts some but not all of the early endocrine/metabolic changes observed in rodent models of the metabolic side effects, and this suggest that antipsychotic effects are not limited to perturbations in glucose metabolism alone. Future prospective clinical studies should focus on identifying which reliable metabolic alterations might be useful as potential screening tools in assessing patient susceptibility to weight gain and diabetes caused by atypical antipsychotics.ClinicalTrials.gov NCT00741026.

    Full Text Available Abstract Background High antibiotic resistance is described in atypical Mycobacteriosis, mainly by Mycobacterium avium complex (MAC. Methods A randomized, double-blind, placebo-controlled clinical trial was carried out in two hospitals to evaluate the effect of interferon (IFN gamma as immunoadjuvant to chemotherapy on patients with atypical mycobacteria lung disease. Patients received placebo or 1 × 106 IU recombinant human IFN gamma intramuscularly, daily for one month and then three times per week up to 6 months as adjuvant to daily oral azithromycin, ciprofloxacin, ethambutol and rifampin. Sputum samples collection for direct smear observation and culture as well as clinical and thorax radiography assessments were done during treatment and one year after. Cytokines and oxidative stress determinations were carried out in peripheral blood before and after treatment. Results Eighteen patients were included in the IFN group and 14 received placebo. Groups were homogeneous at entry; average age was 60 years, 75% men, 84% white; MAC infection prevailed (94%. At the end of treatment, 72% of patients treated with IFN gamma were evaluated as complete responders, but only 36% in the placebo group. The difference was maintained during follow-up. A more rapid complete response was obtained in the IFN group (5 months before, with a significantly earlier improvement in respiratory symptoms and pulmonary lesions reduction. Disease-related deaths were 35.7% of the patients in the placebo group and only 11.1% in the IFN group. Three patients in the IFN group normalized their globular sedimentation rate values. Although differences in bacteriology were not significant during the treatment period, some patients in the placebo group converted again to positive during follow-up. Significant increments in serum TGF-beta and advanced oxidation protein products were observed in the placebo group but not among IFN receiving patients. Treatments were well tolerated

    AIM:To evaluated the role of hyoscine butyl bromide in facilitating retrograde ileoscopy.METHODS:Retrograde terminal ileoscopy was attempted in 200 consecutive patients undergoing colonoscopy. After intubation of the cecum and visualization of the ileocecal valve,butyl bromide injection or normal saline was given intravenously to the patients in a double blind random fashion. The pulse rate and oxygen saturation were measured continuously. After completion of the procedure,endoscopists were then asked to score the ease of intubation and the ease of visualization of the terminal ileum on a visual scale of 1 to 10. The patients were also asked to score the pain after receiving hyoscine butyl bromide injection on a score of 1 to 10.RESULTS:Terminal ileoscopy could be performed in 188 patients. The mean (SD) visual analogue score for the ease of intubation of the cecum was 7.4 (0.65) in the injection group and 5.9 (0.8) in the placebo group (P<0.001). The mean (SD) length of ileum visualized in the injection group was 14.4 (3.3) cm and 10.4 (2.7) cm in the placebo group (P<0.001). The mean (SD) visual analogue score for ease of visualization of the terminal ileum was 7.5 (0.69) in the injection group and 5.9 (0.7) in the placebo group (P<0.001). The pain score experienced by the patients was 6.5 (0.7) in the injection group and 6.7 (0.69) in the placebo group (P<0.008). Although the pulse rate increased significantly in patients receiving the drug,no statistically significant difference was noted in the oxygen saturation between the two groups either before or after administration of the drug. No complications were observed in either of the groups.CONCLUSION:Hyoscine butyl bromide injection is a useful adjunct in helping the intubation and visualizationof terminal ileum during colonoscopy.

    Background: This double-blind, parallel-group, multicenter, phase-3 study was designed to test the noninferiority of paliperidone palmitate 3-month formulation (PP3M) to the currently marketed 1-month formulation (PP1M) in patients (age 18–70 years) with schizophrenia, previously stabilized on PP1M. Methods: After screening (≤3 weeks) and a 17-week, flexible-dosed, open-label phase (PP1M: day 1 [150mg eq. deltoid], day 8 [100mg eq. deltoid.], weeks 5, 9, and 13 [50, 75, 100, or 150mg eq., deltoid/gluteal]), clinically stable patients were randomized (1:1) to PP3M (fixed-dose, 175, 263, 350, or 525mg eq. deltoid/gluteal) or PP1M (fixed-dose, 50, 75, 100, or 150mg eq. deltoid/gluteal) for a 48-week double-blind phase. Results: Overall, 1016/1429 open-label patients entered the double-blind phase (PP3M: n=504; PP1M: n=512) and 842 completed it (including patients with relapse). PP3M was noninferior to PP1M: relapse rates were similar in both groups (PP3M: n=37, 8%; PP1M: n=45, 9%; difference in relapse-free rate: 1.2% [95% CI:-2.7%; 5.1%]) based on Kaplan-Meier estimates (primary efficacy). Secondary endpoint results (changes from double-blind baseline in positive and negative symptom score total and subscale scores, Clinical Global Impression-Severity, and Personal and Social Performance scores) were consistent with primary endpoint results. No clinically relevant differences were observed in pharmacokinetic exposures between PP3M and PP1M. Both groups had similar tolerability profiles; increased weight was the most common treatment-emergent adverse event (double-blind phase; 21% each). No new safety signals were detected. Conclusion: Taken together, PP3M with its 3-month dosing interval is a unique option for relapse prevention in schizophrenia. PMID:26902950

    Objective To evaluate the efficacy and safety of defibrase in patients with acute cerebral infarction by a large sample,multicenter, randomized, double-blind, placebo-controlled clinical trial.Methods Patients with acute cerebral infarction within 12 hours of stroke onset were randomly assigned to receive either an initial intravenous infusion of defibrase 15 U plus normal saline 250 Ml or 250 Ml of normal saline only.Subsequent infusions of defibrase 15 U or placebo (normal saline) were given on the 3rd, 5th, 7th, and 9th day, respectively.Both groups received standard care of acute cerebral infarction. The primary efficacy outcome was functional status(Barthel Index) at 3 months after treatment. Safety outcome were bleeding events and mortality rate. Secondary outcome included Chinese Stroke Scale (CSS) score at 14 days and recurrence rate of stroke at 1 year. Results A total of 1053 patients were enrolled at 46 centers from September 2001 to July 2003, and 527 patients were randomly assigned to receive defibrase and 526 to receive placebo. A similar proportion of patients in both groups completed a full course of treatment. There was a significantly greater proportion of favorable functional status (Barthel Index ≥95) in defibrase group than in placebo group at 3 months (52.2% vs. 42.8%, P < 0.01), and the proportion of dependent functional status (Barthel Index ≤60) was a little lower in defibrase group compared with placebo group(27.7%vs. 32.4%). These differences were more obvious among patients who were treated within 6 hours of stroke onset.Patients in defibrase group had better improvement with respect to CSS score than those in placebo group at 14 days (P <0.05). Recurrence rate of stroke at 1 year was lower in the defibrase group compared with placebo group (6.2% vs. 10.1%,P = 0.053). Patients in defibrase group had higher risk of extracranial bleeding events (4.7%vs. 1.5%, P< 0.01) and a tendency of higher risk of symptomatic intracranial hemorrhage

    Recent studies have suggested that long-term oxytocin administration can alleviate the symptoms of autism spectrum disorder (ASD); however, factors influencing its efficacy are still unclear. We conducted a single-center phase 2, pilot, randomized, double-blind, placebo-controlled, parallel-group, clinical trial in young adults with high-functioning ASD, to determine whether oxytocin dosage and genetic background of the oxytocin receptor affects oxytocin efficacy. This trial consisted of double-blind (12 weeks), open-label (12 weeks) and follow-up phases (8 weeks). To examine dose dependency, 60 participants were randomly assigned to high-dose (32 IU per day) or low-dose intranasal oxytocin (16 IU per day), or placebo groups during the double-blind phase. Next, we measured single-nucleotide polymorphisms (SNPs) in the oxytocin receptor gene (OXTR). In the intention-to-treat population, no outcomes were improved after oxytocin administration. However, in male participants, Clinical Global Impression-Improvement (CGI-I) scores in the high-dose group, but not the low-dose group, were significantly higher than in the placebo group. Furthermore, we examined whether oxytocin efficacy, reflected in the CGI-I scores, is influenced by estimated daily dosage and OXTR polymorphisms in male participants. We found that >21 IU per day oxytocin was more effective than ⩽21 IU per day, and that a SNP in OXTR (rs6791619) predicted CGI-I scores for ⩽21 IU per day oxytocin treatment. No severe adverse events occurred. These results suggest that efficacy of long-term oxytocin administration in young men with high-functioning ASD depends on the oxytocin dosage and genetic background of the oxytocin receptor, which contributes to the effectiveness of oxytocin treatment of ASD.

    A phase IV, multicentre, randomized, double-blind, parallel-group, comparative study was conducted in Japanese subjects with type 2 diabetes mellitus (T2DM) who had inadequate glycaemic control, despite treatment with alogliptin in addition to diet and/or exercise therapy. Subjects with glycated haemoglobin (HbA1c) concentrations of 6.9-10.5% were randomized to receive 16 weeks' double-blind treatment with pioglitazone 15 mg, 30 mg once daily or placebo added to alogliptin 25 mg once daily. The primary endpoint was the change in HbA1c from baseline at the end of treatment period (week 16). Both pioglitazone 15 and 30 mg combination therapy resulted in a significantly greater reduction in HbA1c than alogliptin monotherapy [-0.80 and -0.90% vs 0.00% (the least squares mean using analysis of covariance model); p < 0.0001, respectively]. The overall incidence rates of treatment-emergent adverse events were similar among the treatment groups. Pioglitazone/alogliptin combination therapy was effective and generally well tolerated in Japanese subjects with T2DM and is considered to be useful in clinical settings.

    Full Text Available Abstract Background There is evidence that dyslipidemia is associated with chronic kidney disease (CKD. Experimental studies have established that lipids are damaging to the kidney and animal intervention studies show statins attenuate this damage. Small clinical trials, meta-analyses, observational studies and post-hoc analyses of cardiovascular intervention studies all support the concept that statins can reduce kidney damage in humans. Based on this background, a double blind randomized placebo controlled trial was designed to assess the effectiveness of atorvastatin 10 mg on slowing the progression of kidney disease in a population of patients with CKD. Method/Design The Lipid lowering and Onset of Renal Disease (LORD trial is a three-year, single center, multi-site, double blind, randomized, placebo controlled trial. The primary outcome measure is kidney function measured by eGFR calculated by both Modification of Diet in Renal Disease (MDRD and Cockcroft and Gault equations. Secondary outcome measures include kidney function measured by 24-hour urine creatinine clearance and also 24-hour urinary protein excretion, markers of oxidative stress, inflammation and drug safety and tolerability. Discussion The results of this study will help determine the effectiveness and safety of atorvastatin and establish its effects on oxidative stress and inflammation in patients with CKD.

    Full Text Available Exposure to a specific pulsed electromagnetic field (PEMF has been shown to produce analgesic (antinociceptive effects in many organisms. In a randomized, double-blind, sham-controlled clinical trial, patients with either chronic generalized pain from fibromyalgia (FM or chronic localized musculoskeletal or inflammatory pain were exposed to a PEMF (400 μT through a portable device fitted to their head during twice-daily 40 min treatments over seven days. The effect of this PEMF on pain reduction was recorded using a visual analogue scale. A differential effect of PEMF over sham treatment was noticed in patients with FM, which approached statistical significance (P=0.06 despite low numbers (n=17; this effect was not evident in those without FM (P=0.93; n=15. PEMF may be a novel, safe and effective therapeutic tool for use in at least certain subsets of patients with chronic, nonmalignant pain. Clearly, however, a larger randomized, double-blind clinical trial with just FM patients is warranted.

    Negative symptoms and cognitive deficits are considered core symptoms of schizophrenia, yet treatment for them remains inadequate. Deep-transcranial magnetic stimulation (TMS) is a novel technology that enables non-invasive stimulation of deep layers of the prefrontal cortex. Preliminary evidence suggests that deep-TMS could be effective in the treatment of negative symptoms and cognitive deficits. The current study is the first double-blind, randomized sham-controlled study to examine the feasibility of deep-TMS add-on treatment for negative symptoms and cognitive deficits in schizophrenia. Twenty daily H1 deep-TMS treatments (20Hz, 120% MT) were delivered, in a double-blind, randomized sham-controlled design (n=30). Extensive clinical and cognitive assessments were carried out throughout the study and for an additional one month follow-up period. The results indicate that at the end of the treatment period, negative symptoms (as indicated by the Scale for the Assessment of Negative Symptoms (SANS)) significantly reduced in the TMS group (-7.7), but not in the sham group (-1.9). Differences between the groups were not statistically significant.

    Full Text Available Context Glutamine is the main source of energy of the enterocyte and diarrhea and weight loss are frequent in HIV infected patients. Objective To determine the effect of alanyl-glutamine supplementation on intestinal permeability and absorption in these patients. Methods Randomized double-blinded, placebo-controlled study using isonitrogenous doses of alanyl-glutamine (24 g/day and placebo (glycine, 25 g/day during 10 days. Before and after this nutritional supplementation lactulose and mannitol urinary excretion were determined by high performance liquid chromatography. Results Forty six patients with HIV/AIDS, 36 of whom were male, with 37.28 ± 3 (mean ± standard error years were enrolled. Twenty two and 24 subjects were treated with alanyl-glutamine and with glycine respectively. In nine patients among all in the study protocol that reported diarrhea in the 14 days preceding the beginning of the study, mannitol urinary excretion was significantly lower than patients who did not report this symptom [median (range: 10.51 (3.01–19.75 vs. 15.37 (3.93–46.73; P = 0.0281] and lactulose/mannitol ratio was significantly higher [median (range: 0.04 (0.00–2.89 vs. 0.02 (0.00–0.19; P = 0.0317]. There was also a significant increase in mannitol urinary excretion in the group treated with alanyl-glutamine [median (range: 14.38 (8.25–23.98 before vs 21.24 (6.27–32.99 after treatment; n = 14, P = 0.0382]. Conclusion Our results suggest that the integrity and intestinal absorption are more intensely affected in patients with HIV/AIDS who recently have had diarrhea. Additionally, nutritional supplementation with alanyl-glutamine was associated with an improvement in intestinal absorption.

    A placebo-controlled study was employed to evaluate the effects of oral amrinone in patients with congestive heart failure. After a baseline period of at least 4 weeks of standard treatment for refractory congestive heart failure, oral amrinone was added to the treatment regimen of 173 patients. Patients were predominantly male (89%), aged 24 to 76 years (mean 54), with ischemic (52%) or idiopathic (37%) dilated cardiomyopathy, in New York Heart Association functional class II (40%), III (59%) and IV (1%) and having a mean (+/- standard deviation) left ventricular ejection fraction of 25 +/- 15%. Phase 1: After the addition of amrinone (113 +/- 33 mg three times daily), 52 patients (30%) showed a maximal increase in treadmill exercise time exceeding 2 minutes (Naughton protocol), 72 (42%) had a lesser increase, 24 (14%) developed limiting adverse reactions, 20 (12%) died and 5 dropped out of the study. Fifty-two "responders" (30%) who were free of limiting side effects and had a greater than 2 minute increase in exercise time were randomized in double-blind fashion to continued amrinone or switched to placebo (each plus standard treatment) for an additional 12 weeks. Phase 2: Comparison of 31 of these 52 responders who continued to receive amrinone with the remaining 21 randomized to placebo revealed no significant differences in vital signs, indexes of left ventricular size and function, systolic time intervals or maximal exercise time. Continued follow-up study of patients receiving either amrinone or placebo revealed decreases in exercise times of 7 and 10%, respectively (both p less than 0.05 compared with before randomization). Episodes of worsened congestive heart failure severe enough to mandate termination of double-blind treatment were as frequent in patients taking placebo (4[18%] of 21) as in those taking amrinone (4[13%] of 31; p = NS). The average symptom score and functional class of each treatment group remained comparable. Adverse effects such as

    Erectile dysfunction is a man's persistent or recurrent inability to achieve and maintain erection for a satisfactory sexual relationship. As diabetes is a major risk factor for erectile dysfunction, the prevalence of erectile dysfunction among diabetic men has been reported as 35% to 90%. This randomized, parallel-group, double-blind, placebo-controlled trial investigated the effects of a topical saffron (Crocus sativus L) gel on erectile dysfunction in diabetic men. Patients were randomly allocated to 2 equal groups (with 25 patients each). The intervention group was treated with topical saffron, and the control received a similar treatment with placebo. The 2 groups were assessed using the International Index of Erectile Function Questionnaire before the intervention and 1 month after the intervention. Compared to placebo, the prepared saffron gel could significantly improve erectile dysfunction in diabetic patients (P < .001). This preliminary evidence suggests that saffron can be considered as a treatment option for diabetic men with erectile dysfunction.

    This study evaluates the impact of a milk-based cornstarch porridge fortified with iron, in 4-year olds, compared with control on hemoglobin levels and anemia prevalence. This trial was a cluster-randomized, double-blind one, and used milk-based cornstarch porridge fortified with 10 mg elemental iron (FeSO(4)), daily, during 14 weeks, compared with control. The study population comprised 4-year-old preschoolers (n = 131). Mean hemoglobin values at baseline were found to be 10.6 ± 0.61 g dl(-1) for intervention group, and after intervention 11.5 ± 0.80 g/dl, p porridge fortified with ferrous sulfate increased hemoglobin levels and reduced anemia prevalence in 4-year-old preschoolers.

    IMVAMUNE® is a Modified Vaccinia Ankara-based virus that is being developed as a safer 3rd generation smallpox vaccine. In order to determine the optimal dose for further development, a double-blind, randomized Phase II trial was performed testing three different doses of IMVAMUNE® in 164 healthy volunteers. All three IMVAMUNE® doses displayed a favourable safety profile, with local reactions as the most frequent observation. The 1×108 TCID50 IMVAMUNE® dose induced a total antibody response in 94% of the subjects following the first vaccination and the highest peak seroconversion rates by ELISA (100%) and PRNT (71%). This IMVAMUNE® dose was considered to be optimal for the further clinical development of this highly attenuated poxvirus as a safer smallpox vaccine. PMID:19944151

    The aim of this histologic, double-blind, parallel, randomized controlled trial was to compare anorganic bone mineral-collagen membranes (BB) and betatricalcium phosphate-pericardium collagen membranes (CJ) in a one-stage procedure for horizontal bone augmentation. A biopsy was performed in the regenerated area at abutment connection 6 months after surgery. Five patients were assigned and treated with the BB combination and five patients were treated with the CJ combination. At abutment connection, 6 months after grafting, no significant differences were evident in the histomorphometric comparisons, even if the percentage of residual graft, using the marrow spaces and soft tissue as a reference, tended to be greater in the CJ group (P = .0759).

  12. Lymphoid irradiation in intractable rheumatoid arthritis. A double-blind, randomized study comparing 750-rad treatment with 2,000-rad treatment

    International Nuclear Information System (INIS)

    Twenty patients with intractable rheumatoid arthritis were treated with 750-rad or 2,000-rad lymphoid irradiation in a randomized double-blind comparative study. Over a 12-month followup period, there was a significant improvement in 4 of 7 and 6 of 7 standard parameters of disease activity following treatment with 750 rads and 2,000 rads, respectively. Transient, short-term toxicity was less frequent with the lower dose. In both groups, there was a sustained peripheral blood lymphopenia, a selective depletion of T helper (Leu-3a+) lymphocytes, and reduced in vitro mitogen responses. These changes did not occur, however, in synovial fluid. These results suggest that 750-rad lymphoid irradiation is as effective as, but less toxic than, that with 2,000 rads in the management of patients with intractable rheumatoid arthritis

    Full Text Available Objective: A prospective, randomized and double-blind study was planned to identify the optimum dose of esmolol infusion to suppress the increase in bispectral index values and the movement and hemodynamic responses to tracheal intubation. Materials and methods: One hundred and twenty patients were randomly allocated to one of three groups in a double-blind fashion. 2.5 mg kg-1 propofol was administered for anesthesia induction. After loss of consciousness, and before administration of 0.6 mg kg-1 rocuronium, a tourniquet was applied to one arm and inflated to 50 mm Hg greater than systolic pressure. The patients were divided into 3 groups; 1 mg kg-1 h-1 esmolol was given as the loading dose and in Group Es50 50 μg kg-1 min-1, in Group Es150 150 μg kg-1 min-1, and in Group Es250 250 μg kg-1 min-1 esmolol infusion was started. Five minutes after the esmolol has been begun, the trachea was intubated; gross movement within the first minute after orotracheal intubation was recorded. Results: Incidence of movement response and the ΔBIS max values were comparable in Group Es250 and Group Es150, but these values were significantly higher in Group Es50 than in the other two groups. In all three groups in the 1st minute after tracheal intubation heart rate and mean arterial pressure were significantly higher compared to values from before intubation (p < 0.05. In the study period there was no significant difference between the groups in terms of heart rate and mean arterial pressure. Conclusion: In clinical practise we believe that after 1 mg kg-1 loading dose, 150 μg kg-1 min-1 iv esmolol dose is sufficient to suppress responses to tracheal intubation without increasing side effects.

    Full Text Available Abstract Background The morbidity and mortality associated with depression are considerable and continue to increase. Depression currently ranks fourth among the major causes of disability worldwide, after lower respiratory infections, prenatal conditions, and HIV/AIDS. Crocus sativus L. is used to treat depression. Many medicinal plants textbooks refer to this indication whereas there is no evidence-based document. Our objective was to compare the efficacy of stigmas of Crocus sativus (saffron with imipramine in the treatment of mild to moderate depression in a 6-week pilot double-blind randomized trial. Methods Thirty adult outpatients who met the Diagnostic and Statistical Manual of Mental Disorders, 4th edition for major depression based on the structured clinical interview for DSM IV participated in the trial. Patients have a baseline Hamilton Rating Scale for Depression score of at least 18. In this double-blind, single-center trial, patients were randomly assigned to receive capsule of saffron 30 mg/day (TDS (Group 1 and capsule of imipramine 100 mg/day (TDS (Group 2 for a 6-week study. Results Saffron at this dose was found to be effective similar to imipramine in the treatment of mild to moderate depression (F = 2.91, d.f. = 1, P = 0.09. In the imipramine group anticholinergic effects such as dry mouth and also sedation were observed more often that was predictable. Conclusion The main overall finding from this study is that saffron may be of therapeutic benefit in the treatment of mild to moderate depression. To the best of our knowledge this is the first clinical trial that supports this indication for saffron. A large-scale trial with placebo control is warranted.

    Full Text Available Abstract Background Molecular hydrogen has prominent effects on more than 30 animal models especially of oxidative stress-mediated diseases and inflammatory diseases. In addition, hydrogen effects on humans have been reported in diabetes mellitus type 2, hemodialysis, metabolic syndrome, radiotherapy for liver cancer, and brain stem infarction. Hydrogen effects are ascribed to specific radical-scavenging activities that eliminate hydroxyl radical and peroxynitrite, and also to signal-modulating activities, but the detailed molecular mechanisms still remain elusive. Hydrogen is a safe molecule that is largely produced by intestinal bacteria in rodents and humans, and no adverse effects have been documented. Methods We performed open-label trial of drinking 1.0 liter per day of hydrogen-enriched water for 12 weeks in five patients with progressive muscular dystrophy (PMD, four patients with polymyositis/dermatomyositis (PM/DM, and five patients with mitochondrial myopathies (MM, and measured 18 serum parameters as well as urinary 8-isoprostane every 4 weeks. We next conducted randomized, double-blind, placebo-controlled, crossover trial of 0.5 liter per day of hydrogen-enriched water or placebo water for 8 weeks in 10 patients with DM and 12 patients with MM, and measured 18 serum parameters every 4 weeks. Results In the open-label trial, no objective improvement or worsening of clinical symptoms was observed. We, however, observed significant effects in lactate-to-pyruvate ratios in PMD and MM, fasting blood glucose in PMD, serum matrix metalloproteinase-3 (MMP3 in PM/DM, and serum triglycerides in PM/DM. In the double-blind trial, no objective clinical effects were observed, but a significant improvement was detected in lactate in MM. Lactate-to-pyruvate ratios in MM and MMP3 in DM also exhibited favorable responses but without statistical significance. No adverse effect was observed in either trial except for hypoglycemic episodes in an insulin

    The widely observed between-subject variability in cognitive responses to coffee may have a genetic basis. We evaluated cognitive responses to caffeine throughout three complex cognitive tasks assessing different subdomains of attention, namely Alerting and Orienting (Categorical Search Task) and Executive Control (Stroop Task and Eriksen Flanker Task). We explored whether they are influenced by gene variants affecting adenosine metabolism or catecholamine receptors. We recruited 106 healthy male subjects who were administered, in a double-blind design, 40mL of either a decaffeinated coffee preparation plus 3mg/kg caffeine (caf) or the corresponding vehicle (decaf). The protocol was repeated 24h later with the alternative preparation. Cognitive tasks were performed between 30min and 2h after caf or decaf administration. Each subject underwent ambulatory blood pressure monitoring for 2h. Blood samples were collected for genetic evaluations and for plasma caffeine and catecholamines measures. We found a significant reduction of reaction times in two of the cognitive tasks (Categorical Search Task and Stroop Task) after caf compared with decaf, indicating that caffeine, on average, improved the attention level in the domains under investigation. We also found, however, a great inter-individual variability in the cognitive performance responses to caffeine. In exploring genetic sources for such variability, we found a relation between polymorphisms of adenosine A2A and the caffeine effects on the attentional domains of Orienting and Executive control. In conclusion, variability in the attentional response to coffee may be partly explained by genetic polymorphisms of adenosine and adrenergic receptors. PMID:25819143

    Full Text Available Context and Objectives: The number of people with diabetes is increasing exponentially in India. Owing to a unique "Asian Indian Phenotype," Indians develop diabetes a decade earlier and have an earlier onset of complications than Western populations. Therefore, it is essential to evaluate more effective treatment strategies at an earlier stage of disease progression, such as initial combination therapy, in Indian patients. In this study, we evaluated the efficacy and safety of initial combination therapy with linagliptin plus metformin in comparison to linagliptin or metformin monotherapy in Indian patients with type 2 diabetes mellitus. Methods: This is a subgroup analysis of Indian patients who participated in a Phase III, 24-week, double-blind, placebo-controlled, trial. Overall, 249 Indian patients were randomized to one of six treatment arms (Two free combination therapy arms: Linagliptin 2.5 mg twice daily [bid] + either low [500 mg, n = 36] or high [1000 mg, n = 44] dose metformin bid and four monotherapy arms: Linagliptin 5 mg once daily [qd, n = 40], metformin 500 mg [n = 49] or 1000 mg bid [n = 45], or placebo [n = 23]. Results: The placebo-corrected mean change in glycated hemoglobin from baseline (8.9% to week 24 was −1.83% for linagliptin + metformin 1000 mg bid; −1.46% for linagliptin + metformin 500 mg bid; −1.30% for metformin 1000 mg bid; −1.00% for metformin 500 mg bid; and −0.77% for linagliptin 5 mg qd. None of the patients in the combination therapy arms had hypoglycemia, whereas there was one event in the metformin 1000 mg bid arm. Rates of adverse event were similar across various treatments. Conclusions: In this subgroup analysis of Indian patients, initial combination therapy with linagliptin + metformin was more efficacious in improving glycemic control than the monotherapy arms, with a comparable tolerability profile. The results were comparable to the overall population.

    Background Preemptive analgesia is considered an alternative for treating the postsurgical pain of third molar removal. The aim of this study was to evaluate the preemptive analgesic efficacy of oral ketorolac versus intramuscular tramadol after a mandibular third molar surgery. Material and Methods A parallel, double-blind, randomized, placebo-controlled clinical trial was carried out. Thirty patients were randomized into two treatment groups using a series of random numbers: Group A, oral ketorolac 10 mg plus intramuscular placebo (1 mL saline solution); or Group B, oral placebo (similar tablet to oral ketorolac) plus intramuscular tramadol 50 mg diluted in 1 mL saline solution. These treatments were given 30 min before the surgery. We evaluated the time of first analgesic rescue medication, pain intensity, total analgesic consumption and adverse effects. Results Patients taking oral ketorolac had longer time of analgesic covering and less postoperative pain when compared with patients receiving intramuscular tramadol. Conclusions According to the VAS and AUC results, this study suggests that 10 mg of oral ketorolac had superior analgesic effect than 50 mg of tramadol when administered before a mandibular third molar surgery. Key words:Ketorolac, tramadol, third molar surgery, pain, preemptive analgesia. PMID:27475688

    Full Text Available Abstract Background Neurotoxicity caused by treatment for a brain tumor is a major cause of neurocognitive decline in survivors. Studies have shown that neurofeedback may enhance neurocognitive functioning. This paper describes the protocol of the PRISMA study, a randomized controlled trial to investigate the efficacy of neurofeedback to improve neurocognitive functioning in children treated for a brain tumor. Methods/Design Efficacy of neurofeedback will be compared to placebo training in a randomized controlled double-blind trial. A total of 70 brain tumor survivors in the age range of 8 to 18 years will be recruited. Inclusion also requires caregiver-reported neurocognitive problems and being off treatment for more than two years. A group of 35 healthy siblings will be included as the control group. On the basis of a qEEG patients will be assigned to one of three treatment protocols. Thereafter patients will be randomized to receive either neurofeedback training (n=35 or placebo training (n=35. Neurocognitive tests, and questionnaires administered to the patient, caregivers, and teacher, will be used to evaluate pre- and post-intervention functioning, as well as at 6-month follow-up. Siblings will be administered the same tests and questionnaires once. Discussion If neurofeedback proves to be effective for pediatric brain tumor survivors, this can be a valuable addition to the scarce interventions available to improve neurocognitive and psychosocial functioning.

    Colorectal cancer progresses through multiple distinct stages that are potentially amenable to chemopreventative intervention. Epidermal growth factor receptor (EGFR) inhibitors are efficacious in advanced tumors including colorectal cancer. There is significant evidence that EGFR also plays important roles in colorectal cancer initiation, and that EGFR inhibitors block tumorigenesis. We performed a double-blind randomized clinical trial to test whether the EGFR inhibitor erlotinib given for up to 30 days had an acceptable safety and efficacy profile to reduce EGFR signaling biomarkers in colorectal aberrant crypt foci (ACF), a subset of which progress to colorectal cancer, and normal rectal tissue. A total of 45 patients were randomized to one of three erlotinib doses (25, 50, and 100 mg) with randomization stratified by nonsteroidal anti-inflammatory drug (NSAID) use. There were no unanticipated adverse events with erlotinib therapy. Erlotinib was detected in both normal rectal mucosa and ACFs. Colorectal ACF phosphorylated ERK (pERK), phosphorylated EGFR (pEGFR), and total EGFR signaling changes from baseline were modest and there was no dose response. Overall, this trial did not meet is primary efficacy endpoint. Colorectal EGFR signaling inhibition by erlotinib is therefore likely insufficient to merit further studies without additional prescreening stratification or potentially longer duration of use.

  4. Study Protocol- Lumbar Epidural Steroid Injections for Spinal Stenosis (LESS: a double-blind randomized controlled trial of epidural steroid injections for lumbar spinal stenosis among older adults

    2012-03-01

    Full Text Available Abstract Background Lumbar spinal stenosis is one of the most common causes of low back pain among older adults and can cause significant disability. Despite its prevalence, treatment of spinal stenosis symptoms remains controversial. Epidural steroid injections are used with increasing frequency as a less invasive, potentially safer, and more cost-effective treatment than surgery. However, there is a lack of data to judge the effectiveness and safety of epidural steroid injections for spinal stenosis. We describe our prospective, double-blind, randomized controlled trial that tests the hypothesis that epidural injections with steroids plus local anesthetic are more effective than epidural injections of local anesthetic alone in improving pain and function among older adults with lumbar spinal stenosis. Methods We will recruit up to 400 patients with lumbar central canal spinal stenosis from at least 9 clinical sites over 2 years. Patients with spinal instability who require surgical fusion, a history of prior lumbar surgery, or prior epidural steroid injection within the past 6 months are excluded. Participants are randomly assigned to receive either ESI with local anesthetic or the control intervention (epidural injections with local anesthetic alone. Subjects receive up to 2 injections prior to the primary endpoint at 6 weeks, at which time they may choose to crossover to the other intervention. Participants complete validated, standardized measures of pain, functional disability, and health-related quality of life at baseline and at 3 weeks, 6 weeks, and 3, 6, and 12 months after randomization. The primary outcomes are Roland-Morris Disability Questionnaire and a numerical rating scale measure of pain intensity at 6 weeks. In order to better understand their safety, we also measure cortisol, HbA1c, fasting blood glucose, weight, and blood pressure at baseline, and at 3 and 6 weeks post-injection. We also obtain data on resource utilization

    Full Text Available Background: Dental anxiety is a relatively frequent problem that can lead to more serious problems such as a child entering a vicious cycle as he/she becomes reluctant to accept the required dental treatments. The aim of this randomized double-blind clinical trial study was to evaluate the anxiolytic and sedative effect of pregabalin in children. Materials and Methods: Twenty-five children were randomized to a double-blind placebo-controlled crossover clinical trial. Two visits were scheduled for each patient. At the first visit, 75 mg pregabalin or placebo was given randomly, and the alternative was administered at the next visit. Anxiolytic and sedative effects were measured using the visual analogue scale. The child′s behavior was rated with the Frankl behavioral rating scale and the sedation level during the dental procedure was scored using the Ramsay sedation scale. The unpaired, two-tailed Student′s t-test was used to compare the mean changes of visual analog scale (VAS for anxiety in the pregabalin group with that of the placebo group. A repeated measures MANOVA model was used to detect differences in sedation level in the pregabalin and placebo groups regarding the interaction of 3-time measurements; sub-group analysis was performed using Student′s t-test. The Mann-Whitney U-test was used to analyze the nonparametric data of the Frankl and Ramsay scales. A P < 0.05 was considered significant. Results: The reduction of the VAS-anxiety score from 2 h post-dose was statistically significant in the pregabalin group. From 2 h to 4 h post-dose, the VAS-sedation score increased significantly in the pregabalin group. The child′s behavior rating was not significantly different between the groups. The number of "successful" treatment visits was higher in the pregabalin group compared to the placebo group. Conclusion: Significant anxiolytic and sedative effects can be anticipated 2 h after oral administration of pregabalin without serious

    Full Text Available Abstract Background Arabinogalactan from Larch tree (Larix spp. bark has previously demonstrated immunostimulatory activity. The purpose of this study was to test the hypothesis that ingestion of a proprietary arabinogalactan extract, ResistAid™, would selectively enhance the antibody response to the pneumococcal (pneumonia vaccine in healthy adults. Methods This randomized, double-blind, placebo-controlled, parallel group pilot study included 45 healthy adults who had not previously been vaccinated against Streptococcus pneumoniae. The volunteers began taking the study product or placebo (daily dosage 4.5 g at the screening visit (V1-Day 0 and continued over the entire 72 day study period. After 30 days the subjects received the 23-valent pneumococcal vaccine (V2. They were monitored the following day (V3-Day 31, as well as 21 days (V4-Day 51 and 42 days (V5-Day 72 after vaccination. Responses by the adaptive immune system (antigen specific were measured via pneumococcal IgG antibodies (subtypes 4, 6B, 9V, 14, 18C, 19F, and 23F and salivary IgA levels. Responses by the innate immune system (non-specific were measured via white blood cell counts, inflammatory cytokines and the complement system. Results Vaccination significantly increased pneumococcal IgG levels as expected. The arabinogalactan group demonstrated a statistically significant greater IgG antibody response than the placebo group in two antibodies subtypes (18C and 23F at both Day 51 (p = 0.006 and p = 0.002 and at Day 72 (p = 0.008 and p = 0.041. These same subtypes (18C and 23F also demonstrated change scores from baseline which were significant, in favor of the arabinogalactan group, at Day 51 (p = 0.033 and 0.001 and at Day 72 (p = 0.012 and p = 0.003. Change scores from baseline and mean values were greater in the arabinogalactan group than placebo for most time points in antibody subtypes 4, 6B, 9V, and 19F, but these differences did not reach statistical significance.

Forty-five participants were assigned randomly to 3 groups as A (myrtle berries freeze-dried aqueous extract, 1000 mg/d), B (omeprazol capsules, 20 mg/d), and C (A and B). The assessment at the beginning and the end of the study was done by using a standardized questionnaire of frequency scale for the symptoms of gastroesophageal reflux disease (FSSG). In all groups, both reflux and dyspeptic scores significantly decreased in comparison with the respective baselines. Concerning each group, significant changes were found in FSSG, dysmotility-like symptoms and acid reflux related scores. No significant differences were observed between all groups in final FSSG total scores (FSSG2). Further studies with more precise design and larger sample size may lead to a better outcome to suggest the preparation as an alternative intervention. PMID:26045552

    Background: Electroconvulsive therapy (ECT) is one of the available and the most effective therapies for the treatment of resistant depression. Considering the crucial role of seizure duration on therapeutic response in patients treated with ECT, this study aimed to compare the effect of ketamine and sodium thiopental anesthesia during ECT for treatment of patients with drug-resistant major depression (DRMD). Materials and Methods: In a double-blind randomized clinical trial, 160 patients with DRMD were selected consequently and were assigned randomly into two groups including ketamine 0.8 mg/kg and sodium thiopental 1.5 mg/kg. The seizure duration, recovery time, and the side effects of anesthesia were evaluated after 1-h after anesthesia. Data of recovery time and complication collected in 2nd, 4th, 6th, and 8th ECT. Depression was assessed by Hamilton depression scale. Results: The results indicated that ketamine and sodium thiopental had a significant effect on the reduction of depression scores in patients with DRMD (P ketamine group (P > 0.05). But ketamine was more effective in improvement of depression score and increasing systolic and diastolic blood pressure (P ketamine during ECT therapy increased blood pressure and seizure duration. Therefore, due to lower medical complication and attack rate of seizure, ketamine is an appropriate option for anesthesia with ECT in patients with DRMD. PMID:26440233

    We conducted a 16-week double-blind randomized controlled single-center trial to evaluate the safety and efficacy of dermal rice bran supercritical CO2 extract (RB-SCE) in the treatment of androgenic alopecia. Fifty alopecia patients were randomly assigned to the experimental and placebo groups. The experimental group received a dermal application of 0.5% RB-SCE (8 mL/d) to the head skin for 16 weeks while the control group received a dermal application of placebo. Changes in hair count, diameter, and density were evaluated with a Folliscope(®). Patient satisfaction was evaluated via questionnaire and clinical photographs were rated by dermatologists. The results showed that RB-SCE significantly increased hair density and hair diameter in male subjects. Patient satisfaction and the evaluation of photographs by dermatologists also confirmed the effectiveness of RB-SCE in the treatment of alopecia. No adverse reactions related to RB-SCE were reported. Therefore, RB-SCE shows promise for use in functional cosmetics and pharmaceuticals. PMID:26632177

    Full Text Available Objective: To determine the efficacy of topical curcumin in reducing breast inflammation in women suffering from lactational mastitis. Methods: A randomized double-blind, placebo-controlled study including 63 breastfeeding women with lactational mastitis were randomly assigned to receive curcumin topical cream, one pump every 8 hours for 3 days (n=32 or topical moisturizer as placebo (n=31. Using an index for severity of breast inflammation, all of the patients had moderate breast inflammation before entering the study. The outcome of treatment was evaluated using the same index at 24, 48 and 72 hours of starting the treatment. Results: There was no significant difference between two study groups regarding the baseline characteristics such as age (p=0.361 and duration of lactation (p=0.551. After 72-hour of therapy, patients in curcumin groups had significantly lower rate of moderate (p=0.019 and mild (p=0.002 mastitis. Patients in curcumin group had significantly lower scores for tension (p<0.001, erythema (p<0.001 and pain (p<0.001, after 72-hour of treatment. Conclusion: The results of the current study indicate that topical preparation of curcumin successfully decrease the markers of lactational mastitis such as pain, breast tension and erythema within 72 hours of administration without side effects. Thus, topical preparation of curcumin could be safely administered for those suffering from lactational mastitis after excluding infectious etiologies.

Materials and Methods: A 6-week, single-centered, randomized, double blind, parallel group comparative clinical study was conducted on patients with chronic spontaneous urticaria. Following inclusion and exclusion criteria, 60 patients were recruited and were randomized to two treatment groups and received the respective drugs for 6 weeks. At follow-up, parameters assessed were mean total symptom score (MTSS calculated by adding the mean number of wheals (MNW and the mean pruritus score (MPS, number of wheals, size of wheal, scale for interference of wheals with sleep (SIWS. Results: Both the drugs significantly reduced the MTSS, number of wheals, size of wheal, scale for interference of wheals with sleep, but olopatadine was found to be superior. In olopatadine group, there was significantly higher reduction in MTSS (p = 0.01, Number of wheals (P < 0.05, Size of wheals (p < 0.05, Scale for intensity of erythema (p < 0.05 and change in eosinopils count (p = 0.015 than that of rupatadine. Incidence of adverse effects was found to be less in olopatadine group when compared with rupatadine group. Cost effectiveness ratio was less in olopatadine group as compared to rupatadine group throughout the treatment. Conclusions: Olopatadine is a better choice in chronic spontaneous urticaria in comparison to rupatadine due to its better efficacy, safety and cost effectiveness profile.

    [Purpose] Improved gait efficiency is one of the goals of therapy for children with cerebral palsy (CP). Postural insoles can allow more efficient gait by improving biomechanical alignment. The aim of the present study was to assess the effect of postural insoles on gait performance of children with CP classified as levels I or II of the Gross Motor Function Classification System (GMFCS). [Subjects and Methods] the study was a randomized controlled double-blind clinical trial. After meeting the legal aspects and the eligibility criteria, 10 children between four and 12 years old were randomly divided into a two groups: a control group (n=5), and an experimental group (n=5). Children in the control group used a placebo insoles, and children in the experimental group used postural insoles. Evaluation consisted of three-dimensional gait analysis under three conditions: barefoot, shoes without insoles and shoes with postural insoles or shoes with placebo insoles. [Results] Regarding the immediate effects of insole use, significant improvements in gait velocity and cadence were observed in the experimental group in comparison to the control group. [Conclusion] The use of postural insoles led to improvements in gait velocity and cadence of the children with cerebral palsy classified as levels I or II of the GMFCS.

    Full Text Available Several studies have shown that a large number of patients who are fulfilling the criteria for irritable bowel syndrome (IBS are sensitive to gluten. The aim of this study was to evaluate the effect of a gluten-free diet on gastrointestinal symptoms in patients with IBS. In this double-blind randomized, placebo-controlled trial, 148 IBS patients fulfilling the Rome III criteria were enrolled between 2011 and 2013. However, only 72 out of the 148 commenced on a gluten-free diet for up to six weeks and completed the study; clinical symptoms were recorded biweekly using a standard visual analogue scale (VAS. In the second stage after six weeks, patients whose symptoms improved to an acceptable level were randomly divided into two groups; patients either received packages containing powdered gluten (35 cases or patients received placebo (gluten free powder (37 cases. Overall, the symptomatic improvement was statistically different in the gluten-containing group compared with placebo group in 9 (25.7%, and 31 (83.8% patients respectively (p < 0.001. A large number of patients labelled as irritable bowel syndrome are sensitive to gluten. Using the term of IBS can therefore be misleading and may deviate and postpone the application of an effective and well-targeted treatment strategy in gluten sensitive patients.

    Full Text Available Abstract In ageing men testosterone levels decline, while cognitive function, muscle and bone mass, sexual hair growth, libido and sexual activity decline and the risk of cardiovascular diseases increase. We set up a double-blind, randomized placebo-controlled trial to investigate the effects of testosterone supplementation on functional mobility, quality of life, body composition, cognitive function, vascular function and risk factors, and bone mineral density in older hypogonadal men. We recruited 237 men with serum testosterone levels below 13.7 nmol/L and ages 60–80 years. They were randomized to either four capsules of 40 mg testosterone undecanoate (TU or placebo daily for 26 weeks. Primary endpoints are functional mobility and quality of life. Secondary endpoints are body composition, cognitive function, aortic stiffness and cardiovascular risk factors and bone mineral density. Effects on prostate, liver and hematological parameters will be studied with respect to safety. Measure of effect will be the difference in change from baseline visit to final visit between TU and placebo. We will study whether the effect of TU differs across subgroups of baseline waist girth ( At baseline, mean age, BMI and testosterone levels were 67 years, 27 kg/m2 and 10.72 nmol/L, respectively.

    Full Text Available A gluten-free diet (GFD is currently the only available treatment for patients with celiac disease (CD. Several clinical trials have demonstrated that most celiac patients can tolerate a medium-high quantity of oats without any negative clinical effects; however, the inclusion of oats in GFD is still a matter of debate. In this study, Italian children with CD were enrolled in a 15-month, randomized, double-blind, placebo-controlled multicenter trial. Participants were randomized in two groups following either A-B treatment (6 months of diet “A”, 3 months of standard GFD, 6 months of diet “B”, or B-A treatment (6 months of diet “B”, 3 months of standard GFD, 6 months of diet “A”. A and B diets included gluten-free (GF products (flour, pasta, biscuits, cakes and crisp toasts with either purified oats or placebo. Clinical data (Gastrointestinal Symptoms Rate Scale [GSRS] score and intestinal permeability tests (IPT, were measured through the study period. Although the study is still blinded, no significant differences were found in GSRS score or the urinary lactulose/mannitol (L/M ratio between the two groups after 6 months of treatment. These preliminary results suggest that the addition of non-contaminated oats from selected varieties in the treatment of children with CD does not determine changes in intestinal permeability and gastrointestinal symptoms.

    Providing appropriate prosthetic feet to those with limb loss is a complex and subjective process influenced by professional judgment and payer guidelines. This study used a small load cell (Europa™) at the base of the socket to measure the sagittal moments during walking with three objective categories of prosthetic feet in eleven individuals with transtibial limb loss with MFCL K2, K3 and K4 functional levels. Forefoot stiffness and hysteresis characteristics defined the three foot categories: Stiff, Intermediate, and Compliant. Prosthetic feet were randomly assigned and blinded from participants and investigators. After laboratory testing, participants completed one week community wear tests followed by a modified prosthetics evaluation questionnaire to determine if a specific category of prosthetic feet was preferred. The Compliant category of prosthetic feet was preferred by the participants (P=0.025) over the Stiff and Intermediate prosthetic feet, and the Compliant and Intermediate feet had 15% lower maximum sagittal moments during walking in the laboratory (P=0.0011) compared to the Stiff feet. The activity level of the participants did not change significantly with any of the wear tests in the community, suggesting that each foot was evaluated over a similar number of steps, but did not inherently increase activity. This is the first randomized double blind study in which prosthetic users have expressed a preference for a specific biomechanical characteristic of prosthetic feet: those with lower peak sagittal moments were preferred, and specifically preferred on slopes, stairs, uneven terrain, and during turns and maneuvering during real world use.

    Aim: To conduct a double-blind, placebo-controlled randomized and dose-ranging study to evaluate the safety and efficacy of the extract of Ganoderma lucidum (G. lucidum) in men with lower urinary tract symptoms (LUTS). Methods: We enrolled male volunteers (> 50 years) with an International Prostate Symptom Score (IPSS; questions 1-7)≥ 5 and a prostate-specific antigen (PSA) value < 4 ng/mL. Volunteers were randomized into groups of placebo (n = 12), G. lucidum of 0.6 mg (n = 12), 6 mg (n = 12) or 60 mg (n = 14), administered once daily. Efficacy was measured as a change from baseline in IPSS and the peak urine flow rate (Qmax). Prostate volume and residual urine were estimated by ultrasonography, and blood tests, including PSA levels, were measured at baseline and at the end of the treatment. Results: The overall administration was well tolerated, with no major adverse effects. Statistical significances in the magnitude of changes between the experimental groups were observed at weeks 4 and 8. No changes were observed with respect to Qmax, residual urine, prostate volume or PSA levels. Conclusion: The extract of G. lucidum was well tolerated and an improvement in IPSS was observed. The recommended dose of the extract of G. lucidum is 6 mg in men with LUTS. (Asian J Androl 2008 Jul; 10: 651-658)

    The newly injectable cyclooxygenase-2 selective nonsteroidal antiinflammatory drug, parecoxib, has never been compared with propacetamol, a parenteral formulation of acetaminophen. In this prospective, randomized, double-blind, double-dummy study, we randomly assigned 182 patients scheduled for initial inguinal hernia repair under general anesthesia to receive a single injection of 40 mg parecoxib or 2 injections of 2 g propacetamol within the first 12 h after surgery. The study variables were morphine consumption, pain at rest and while coughing, and patient satisfaction throughout the first 12 h postoperatively. For statistical analysis, we used the Student's t-test, chi(2), and covariance analysis. Total morphine consumption did not differ between the two groups. Pain was less intense in the parecoxib group at rest (P = 0.035) but did not differ for pain while coughing. The incidence of side effects was similar. Significantly more patients in the parecoxib group rated their pain management as good or excellent (87% versus 70% in the propacetamol group, P = 0.001). Within the first 12 h after inguinal hernia repair in adult patients, a single injection of parecoxib 40 mg compares favorably with 2 injections of propacetamol 2 g. PMID:15845675

    Cough is a frequent symptom associated to upper respiratory tract infections (URTIs) and, although being self-limiting, it might deeply affect the quality of life. Homeopathic products are often employed by patients to treat cough, but the evidence on their efficacy is scarce. Thus, we tested the efficacy of a homeopathic syrup in treating cough arising from URTIs with a randomized, double blind, placebo controlled clinical trial. Patients were treated with either the homeopathic syrup or a placebo for a week, and recorded cough severity in a diary by means of a verbal category-descriptive score for two weeks. Sputum viscosity was assessed with a viscosimeter before and after 4 days of treatment; patients were also asked to provide a subjective evaluation of viscosity. Eighty patients were randomized to receive placebo (n = 40) or the homeopathic syrup (n = 40). All patients completed the study. In each group cough scores decreased over time, however, after 4 and 7 days of treatment, cough severity was significantly lower in the homeopathic group than in the placebo one (p syrup employed in the study was able to effectively reduce cough severity and sputum viscosity, thereby representing a valid remedy for the management of acute cough induced by URTIs.

    Polymorphous light eruption (PMLE) is an idiopathic photodermatosis elicited by UV radiation (UVR). The objective of this double-blind, randomized, controlled, intraindividual, bilateral comparison was to determine the efficacy of the UVA filters (ecamsule, avobenzone) present in the new sun protection factor (SPF) 40 sunscreen cream in preventing PMLE in maximized outdoor conditions (ie, exaggerated sun exposure). Safety also was assessed. Each participant was treated with SPF 40 sunscreen cream containing ecamsule 3%, octocrylene 10%, avobenzone 2%, and titanium dioxide 5% (tetrad) on one side of the body and either an ecamsule-deprived (triad-E) or avobenzone-deprived (triad-A) cream on the other side. Participants were subsequently exposed to incremental doses of sunlight for up to 6 days. The primary efficacy assessment was a composite relative success rate with 3 components. Success was defined as either a delayed time to onset of PMLE or a lower global severity of PMLE comparing one side of the body to the other side in the same participant. Safety evaluations included systemic adverse events (AEs). Of the 144 participants enrolled and randomized, 22 did not experience PMLE during the study duration under these maximized sun exposure conditions. A significantly greater number of successes were detected on the tetrad-treated side compared with either triad: 41 of 73 participants (56%) versus 8 of 73 participants (11%; Ptitanium dioxide 5% prevented PMLE flares significantly better than similar formulations with only one of the UVA filters (triad-E treatment group, Pfilter.

    Below the toxic plasma level of nortriptyline (NT) an upper therapeutic limit has been postulated in patients with endogenous depression. If so the clinical significance is obvious and a double-blind, randomized study was performed in order to solve this problem. Two groups of patients were controlled at different plasma levels (less than 150 ng/ml and less than 180 ng/ml). The degree of depression was rated weekly. Only about one third (n equals 24) of the patients originally included, were carried through the full protocol, the most prominent reason for drop out beeing spontaneous remission during an initial placebo period. After 4 weeks of NT treatment the majority in the high level group was still depressed, but the difference barely significant (P equals 5.5%). However, a randomized reduction of the plasma level among the patients at the high level resulted in a significant correlation to remission. Evaluation of the total material after 6 weeks of NT treatment demonstrated a strong correlation of high plasma level to poor antidepressive effect of NT. No correlation could be obtained between side-effects, which were few, and plasma level. The non-proteinbound fraction in plasma was found to 7% (SD 1.83) by simultaneous determinations of NT in plasma and CSF in 13 patients. The variation in the proteinbinding was not likely to invalidate the over all results based on total NT determination. A therapeutic plasma range of 50-150 ng/ml is recommended. PMID:766041

    Full Text Available Introduction: There is limited evidence that ginger (Zingiber Officinale powder consumption is effective to relieve the pain and inflammation due to special phytichemicals. The aim of this study was to investigate the effect of ginger powder supplementation in pain improvement in patients with knee osteoarthritis. Methods: This double-blind randomized clinical trial was conducted on 120 outpatients with knee osteoarthritis of moderate pain. Patients were randomly assigned to two groups: receiving ginger powder supplement and placebo. Ginger and placebo groups received two identical capsules per day for 12 weeks. Each capsule contained 500 mg ginger powder or starch. Pain severity was measured by VAS (Visual Analog Scale at first and after 3 months. A responder was defined as a reduction in pain of > 1.5 cm on a visual analog scale (VAS. Results: Before intervention, there was no significant difference between the two groups in severity of pain. However, after ginger supplementation, pain score decreased in ginger group. After 12 weeks, Pain reduction was more significant in ginger group than placebo. Response to intervention was 88% and 14% in ginger and placebo groups, respectively. There was statistically significant difference between both groups in response to intervention (p<0.001. Conclusion: The results of this study showed that ginger powder supplementation was effective in reducing pain in patients with knee osteoarthritis, therefore it is recommended as a safe supplement for these patients

Methods Sixty patients were randomized into CHX and FBP groups. Following OHI and scaling and root planing (SRP), baseline pocket depth (PD) measurements, gingival recession and bleeding on probing (BOP) were performed and repeated at week 4 and 8. The assigned chip was placed at weeks 0, 1, 2, 3, 5, 7. Results Mean PD reduction in the CHX group was 2.08 mm (7.17 to 5.09, p < 0.0001). Mean PD reduction in the FBP group was 2.27 mm (6.72 to 4.45, p < 0.0001). Ninety-seven percentage and 95% of these sites exhibited PD reduction ≥1 mm, while 38% and 34% of the sites exhibited PD ≥3 mm (FBP and CHX, respectively). Clinical attachment level gain (1.66 and 1.95 mm, respectively) was statistically significant (p < 0.0001). Baseline BOP dropped from 98% and 100% to 24% and 30% for the CHX and FBP groups, respectively (p < 0.0001). Conclusion Frequent applications of CHX and FBP chips resulted in a significant improvement in the periodontal condition in these sites. Furthermore studies will be required to compare this new treatment regimen to SRP or SRP with single chip application. PMID:22092475

    A gluten-free diet (GFD) is currently the only available treatment for patients with celiac disease (CD). Several clinical trials have demonstrated that most celiac patients can tolerate a medium-high quantity of oats without any negative clinical effects; however, the inclusion of oats in GFD is still a matter of debate. In this study, Italian children with CD were enrolled in a 15-month, randomized, double-blind, placebo-controlled multicenter trial. Participants were randomized in two groups following either A-B treatment (6 months of diet "A", 3 months of standard GFD, 6 months of diet "B"), or B-A treatment (6 months of diet "B", 3 months of standard GFD, 6 months of diet "A"). A and B diets included gluten-free (GF) products (flour, pasta, biscuits, cakes and crisp toasts) with either purified oats or placebo. Clinical data (Gastrointestinal Symptoms Rate Scale [GSRS] score) and intestinal permeability tests (IPT), were measured through the study period. Although the study is still blinded, no significant differences were found in GSRS score or the urinary lactulose/mannitol (L/M) ratio between the two groups after 6 months of treatment. These preliminary results suggest that the addition of non-contaminated oats from selected varieties in the treatment of children with CD does not determine changes in intestinal permeability and gastrointestinal symptoms.

    Several studies have been in favor of fungi as a possible pathogenesis of chronic rhinosinusitis (CRS); however, to date, there is no scientific consensus about the use of antifungal agents in disease management. The aim of the present study was to investigate the efficacy of intranasal fluconazole in improving disease symptoms and objective outcomes of patients with CRS. A randomized, double-blind, placebo-controlled study was conducted on 54 patients who were diagnosed with CRS and had not been responsive to routine medical treatments. They were randomly assigned to receive either fluconazole nasal drop 0.2 % or placebo in addition to the standard regimen for a duration of 8 weeks. Patients' outcomes were evaluated according to Sino-Nasal Outcome Test 20 (SNOT-20), endoscopic scores, and Computed Tomography (CT) scores. No statistically significant difference was found in SNOT-20 (p = 0.201), endoscopic (p = 0.283), and CT scores (p = 0.212) of the patients at baseline and after 8-week course of treatment between drug and placebo group. Similar to many studies, the use of topical antifungal treatment for patients with CRS was not shown to be significantly effective. However, further studies are needed to obtain high levels of consistent evidence in order to arrive at a decision whether antifungal therapy is effective in management of CRS or not. PMID:27065776

    Cerebrolysin has exhibited neuroprotective as well as neurotrophic properties in various animal models of cerebral ischaemia and has shown clinical efficacy and good safety in several small controlled clinical studies in ischaemic stroke. Therefore, a large double-blind placebo-controlled randomized clinical trial was launched in Asia to prove the validity of this treatment strategy. In the more than 50 participating centres patients with acute ischemic hemispheric stroke are randomized within 12 hours of symptoms onset to treatment (30 ml Cerebrolysin diluted in physiologic saline) or placebo (saline) given as intravenous infusion once daily added to standard care for 10 days. The patients are followed with regular visits for 90 days. Efficacy is evaluated on day 90 by three outcome scales - modified Rankin Scale, Barthel Index and NIH Stroke Scale - combined to single global directional test. Additionally, adverse events are documented to prove safety. In this study a total of 1060 patients will be included and analysis of data will be completed in 2010. If positive, this trial will add an effective strategy to the treatment of acute ischaemic stroke.

    Antibiotic-associated diarrhea (AAD) is a common complication of antibiotic use. There is growing interest in probiotics for the treatment of AAD and Clostridium difficile infection because of the wide availability of probiotics. The aim of this multicenter, randomized, placebo-controlled, double-blind trial was to assess the efficacy of probiotic Lactobacillus (Lacidofil® cap) for the prevention of AAD in adults. From September 2008 to November 2009, a total of 214 patients with respiratory tract infection who had begun receiving antibiotics were randomized to receive Lactobacillus (Lacidofil® cap) or placebo for 14 days. Patients recorded bowel frequency and stool consistency daily for 14 days. The primary outcome was the proportion of patients who developed AAD within 14 days of enrollment. AAD developed in 4 (3.9%) of 103 patients in the Lactobacillus group and in 8 (7.2%) of 111 patients in the placebo group (P=0.44). However, the Lactobacillus group showed lower change in bowel frequency and consistency (50/103, 48.5%) than the placebo group (35/111, 31.5%) (P=0.01). Although the Lacidofil® cap does not reduce the rate of occurrence of AAD in adult patients with respiratory tract infection who have taken antibiotics, the Lactobacillus group maintains their bowel habits to a greater extent than the placebo group.

    The aim of this randomized, double-blind, controlled study was to evaluate the antidandruff activity exerted by a new shampoo on patients affected by dandruff and/or mild seborrheic dermatitis by means of both D-squame technique coupled with image analysis and clinical assessments. Thirty-four patients were enrolled and 1:1 randomly assigned to either a test shampoo or a comparative shampoo group. Treatment schedule was twice a week for 4 weeks. The D-squame technique was shown to be able to objectively record variations in scalp desquamation both between test and comparative groups and within the same group over time. The results obtained with this instrumental approach showed a statistically significant reduction by 52% vs baseline after 2 weeks of treatment. There was an even greater reduction after 4 weeks (-66%). This reduction was statistically significant compared with the comparative group at the same time points. The analysis of all the other parameters (except Wood's lamp) confirmed the superiority of the test vs the comparative shampoo. The test shampoo proved to be safe, well tolerated, and accepted by the patients for cosmetic acceptability and efficacy. The study confirmed the antidandruff efficacy of the test shampoo and its superiority vs the comparative shampoo.

  15. Intraoperative Low-Dose Ketamine Infusion Reduces Acute Postoperative Pain Following Total Knee Replacement Surgery: A Prospective, Randomized Double-Blind Placebo-Controlled Trial

    International Nuclear Information System (INIS)

    Objective: To evaluate the effect of intraoperative low-dose ketamine with general anesthesia on postoperative pain after total knee replacement surgery. Study Design: A randomized, double-blind comparative study. Place and Duration of Study: Ankara Numune Training and Research Hospital, Turkey, from January and June 2011. Methodology: Sixty adults undergoing total knee arthroplasty were enrolled in this study. The patients were randomly allocated into two groups of equal size to receive either racemic ketamine infusion (6.25 g/kg/minute) or the same volume of saline. A visual analogue scale (VAS) was used to measure each patient's level of pain at 1, 3, 6, 12, and 24 hours after surgery. Time to first analgesic request, postoperative morphine consumption and the incidence of side effects were also recorded. Results: Low-dose ketamine infusion prolonged the time to first analgesic request. It also reduced postoperative cumulative morphine consumption at 1, 3, 6, 12, and 24 hours postsurgery (p < 0.001). Postoperative VAS scores were also significantly lower in the ketamine group than placebo, at all observation times. Incidences of side effects were similar in both study groups. Conclusion: Intraoperative continuous low-dose ketamine infusion reduced pain and postoperative analgesic consumption without affecting the incidence of side effects. (author)

    Full Text Available Abstract Background Major surgical procedures facilitate systemic endotoxinemia and formation of free radicals with subsequent inflammatory changes that can influence the postoperative course. Experimental data suggest that preoperative supraphysiological doses of melatonin, a potent immuno-modulator and antioxidant, would decrease postoperative infectious and non-infectious complications induced by major abdominal surgery. Methods/Design A randomized controlled double blind single center clinical trial with two study arms comprising a total of 40 patients has been designed to assess the effects of a single preoperative dose of melatonin before major liver resection. Primary endpoints include the determination of safety and tolerance of the regimen as well as clinical parameters reflecting pathophysiological functions of the liver. Furthermore, data on clinical outcome (infectious and non-infectious complications will be collected as secondary endpoints to allow a power calculation for a randomized clinical trial aiming at clinical efficacy. Discussion Based on experimental data, this ongoing clinical trial represents an advanced element of the research chain from bench to bedside in order to reach the highest level of evidence-based clinical facts to determine if melatonin can improve the general outcome after liver resection.

    Purpose: To investigate whether magnesium oxide during external-beam radiotherapy for prostate cancer reduces intrafraction prostate motion in a double-blind, placebo-controlled randomized trial. Methods and Materials: At the Department of Radiotherapy, prostate cancer patients scheduled for intensity-modulated radiotherapy (77 Gy in 35 fractions) using fiducial marker-based position verification were randomly assigned to receive magnesium oxide (500 mg twice a day) or placebo during radiotherapy. The primary outcome was the proportion of patients with clinically relevant intrafraction prostate motion, defined as the proportion of patients who demonstrated in {>=}50% of the fractions an intrafraction motion outside a range of 2 mm. Secondary outcome measures included quality of life and acute toxicity. Results: In total, 46 patients per treatment arm were enrolled. The primary endpoint did not show a statistically significant difference between the treatment arms with a percentage of patients with clinically relevant intrafraction motion of 83% in the magnesium oxide arm as compared with 80% in the placebo arm (p = 1.00). Concerning the secondary endpoints, exploratory analyses demonstrated a trend towards worsened quality of life and slightly more toxicity in the magnesium oxide arm than in the placebo arm; however, these differences were not statistically significant. Conclusions: Magnesium oxide is not effective in reducing the intrafraction prostate motion during external-beam radiotherapy, and therefore there is no indication to use it in clinical practice for this purpose.

    BACKGROUND: A eutectic mixture of lidocaine and prilocaine (EMLA) has been shown to be effective in reducing pain from needle sticks, including those associated with blood sampling and intravenous insertion. OBJECTIVE: To evaluate the effectiveness of EMLA cream applied before needle puncture for local anesthetic administration before minor surgical procedures in this double-blind, randomized, controlled, parallel-group study. MATERIALS AND METHODS: Patients were randomly assigned to receive EMLA or placebo cream (Aqueous) applied under an occlusive dressing. After the procedure, patients were asked to rate the needle prick and procedure pain on a visual analog scale (0=no pain; 10=maximum pain). RESULTS: A total of 94 minor surgical procedures (49 in EMLA and 45 in control) were performed. The mean needle-stick pain score in the EMLA group was significantly lower than in the control group (2.7 vs. 5.7, p<.001, Mann-Whitney U-test). There was also significantly lower procedure pain in the EMLA group than in the control group (0.83 vs. 1.86, p=.009). There were no complications associated with the use of EMLA. CONCLUSION: EMLA effectively reduces the preprocedural needle-stick pain and procedural pain associated with minor surgical procedures.

  20. Effect of three different dosages of magnesium sulfate on attenuating hemodynamic responses after electroconvulsive therapy: a randomized, double-blind, placebo-controlled trial

    International Nuclear Information System (INIS)

    Objective: The purpose of this randomized, double-blind, placebo-controlled crossover study was to compare the efficacy of three different dosages of MgSO/sub 4/ administration (10, 20, and 30 mg/kg) versus placebo on attenuation of cardiovascular response to electroconvulsive therapy (ECT). Methodology: Thirty-five adult patients scheduled for 8 ECT sessions were randomly assigned to be allocated twice into one of the four study groups: MgSO/sub 4/ 10 mg/kg (M10), MgSO/sub 4/ 20 mg/ kg (M20), MgSO/sub 4/ 30 mg/kg (M30), and placebo control (P). Systolic (SAP), diastolic (DAP) and mean arterial pressure (MAP) and heart rate (HR) were recorded at 0, 1, 3, and 10 minutes after termination of ECT-induced seizures. Duration of electroencephalographs (EEGs) and motor seizures and peak HR during convulsions were also recorded. Results: Changes in SAP, DAP, and MAP were significantly attenuated at 0, one, and three minutes after ECT in groups M20 and M30 compared with group P (P< 0.05). Peak HR changes were significantly less in groups M20 and M30 compared with groups M10 and P (P< 0.05). Duration of motor and EEG seizure activity was not significantly different among the four groups. Conclusion: Administration of either 20 or 30 mg/kg MgSO/sub 4/ significantly attenuated increased blood pressure and peak HR after ECT without decreasing seizure duration. (author)

    Patients with atopic dermatitis (AD) have an epidermal barrier dysfunction, which allows invasion of allergens to occur. Stratum corneum skin barrier is formed by corneocytes and extracellular lipids extruded from the epidermal lamellar bodies. In a controlled, randomized, double-blinded, right-left comparison study we investigated the effect of pimecrolimus (PIM) cream compared with triamcinolone acetonide cream (TA) on the skin barrier in 15 patients with symmetrical elbow lesions of AD. In punch biopsies, before and after treatment, skin lipid bilayer and lamellar body structure were examined by transmission electron microscopy (TEM). Partial Eczema Area and Severity Index (pEASi), stratum corneum hydration, and transepidermal water loss (TEWL) were monitored on days 1, 8 and 22. The pEASi was significantly more improved with TA compared with PIM, whereas stratum corneum hydration was slightly more improved after treatment with PIM. The TEM revealed a strong reduction in lamellar bodies in lesional skin of AD; only 32% of the lamellar bodies were normal. A significantly higher number of normal lamellar bodies was found after 3 weeks of treatment with PIM (58%; p < 0.005). An increase in lamellar bodies also occurred with TA treatment (46%; p < 0.05); however, significantly less than with PIM (p < 0.05). Clinical score and TEWL were more improved after treatment with TA, whereas the lamellar bodies were more normal after treatment with PIM. PMID:23571785

    Five corticosteroid ointments and placebo were compared in 17 volunteers with regard to their influence on normal skin under occlusive conditions. Each volunteer had six simultaneous applications on the forearms and six on the back. The trial was double-blind and lasted 4 weeks. The ointments were placed in randomized order. The treatments were 0.1 and 0.03% domoprednate, 0.1% hydrocortisone butyrate, 0.1% betamethasone valerate, 0.05% clobetasole propionate and placebo. Skin thickness was measured on days 0, 7, 14, 21 and 28, transepidermal water loss on days 0, 14 and 28, while blood flow and telangiectasias were evaluated only on day 28 at termination of the trial. The skin thickness became significantly reduced on all corticosteroids, but not on placebo; 0.03% domoprednate, however, tended to have an intermediate position between placebo and the other ointments. The transepidermal water loss did not change. Rating of telangiectasia under stereomicroscope showed a significantly lower score after 0.03% domoprednate and placebo as compared to the other ointments. Assessment of telangiectasia by laser-Doppler flowmetry showed a similar tendency. It is concluded that 0.1% domoprednate is comparable to other topical corticosteroids with respect to atrophogeneity and formation of telangiectasia, but the 0.03% concentration seems to result in fewer side effects.

    Full Text Available Abstract Background & the purpose of the study Prevalence of type 2 diabetes mellitus (T2DM is increasing worldwide. To reduce its risk and progression, preventive strategies are needed. Vitamin supplementation such as vitamin D is one of the strategies. This study was designed to investigate the effect of injection of vitamin D on insulin resistance and anthropometric parameters in T2DM. Methods This randomized double-blind clinical trial was conducted with 42 diabetic patients in two groups; intervention group with single intramuscular injection of 300,000 International Unit (IU of vitamin D3 and the placebo group. After recording demographic and anthropometric factors (waist circumference, blood pressure and body mass index, fasting blood samples was taken for measurement of blood glucose, 25-hydroxyvitamin D3 (25-OHD3, insulin, glycosylated hemoglobin A1c (HbA1c and estimation of Homeostasis Model Assessment Index (HOMA in two times; before study and after three months. Results Two groups had similar baseline characteristics (each group = 21 subjects. Three months after vitamin D injection, HbA1c, anthropometric factors and HOMA index in intervention group stayed constant, however, serum 25- OHD3 was significantly increased (p = 0.007. Conclusion The present data is not convincing and further studies with large sample sizes are needed to show the definite effect of injection of vitamin D on control of diabetes and its risk.

    Boswellic acids (BAs) are pentacyclic triterpenes with strong anti-inflammatory activity; their most important source is the extract of the gum resin of Boswellia serrata, a tropical tree that grows in India and Africa. In the present randomized, double-blind, split-face, comparative study we have assessed efficacy, tolerability, and safety of a base cream containing 0.5 % BAs as compared to the same cream without these active ingredients in the treatment of clinical manifestations of photoaging of facial skin. Fifteen female volunteers were enrolled; they applied creams once daily for 30 days. At baseline, at the end of the treatment, and after a 2-month follow-up, clinical findings were assessed according to the Dover classification scale for photoaging and by biophysical and ecographic measurements. We registered a significant improvement of tactile roughness and fine lines in the half side of the face treated with BAs; noninvasive instrumental diagnostic investigations showed an improvement of elasticity, a decrease of sebum excretion, and a change of echographic parameters suggesting a reshaping of dermal tissue. The treatment was always well tolerated without adverse effects. The present findings seem to indicate that the topical application of BAs may represent a suitable treatment option for selected features of skin photoaging.

    Hyperlipidemia is a common metabolic disorder contributing to morbidities and mortalities due to cardiovascular and cerebrovascular diseases. Conventional antihyperlipidemic drugs have limited efficacies and important side effects, so that alternative lipid lowering agents are needed. Salvia officinalis L. (sage) leaves have PPAR γ agonistic, pancreatic lipase and lipid absorption inhibitory, antioxidant, lipid peroxidation inhibitory and antiinflammatory effects. Thus, in this randomized double-blind placebo-controlled clinical trial with 67 hyperlipidemic (hypercholesterolemic and/or hypertriglyceridemic) patients aged 56.4 ± 30.3 years (mean ± SD), the effects of taking sage leaf extract (one 500 mg capsule every 8 h for 2 months) on fasting blood levels of lipids, creatinine and liver enzymes including SGOT and SGPT were evaluated in 34 patients and compared with the placebo group (n = 33). The extract lowered the blood levels of total cholesterol (p  0.05) compared with the placebo group at the endpoint. No adverse effects were reported. The results suggest that sage may be effective and safe in the treatment of hyperlipidemia.

    A randomized, double-blind, placebo-controlled clinical trial was conducted to evaluate the safety, reactogenicity and the immunogenicity of a 2 x 10(9)CFU dose of the 638 lyophilized live attenuated cholera vaccine for oral administration, formulated and produced at Finlay Institute, City of Havana, Cuba. Thirty-six healthy female and male adult volunteers from 18 to 40 years old were involved, clinically examined and laboratory tested after the informed consent signature. Adverse events were monitored and seroconversion rates and geometrical mean titer (GMT) of vibriocidal antibodies were tested in volunteer's sera samples. Neither serious adverse events nor other damages to the volunteers due to vaccine or placebo feeding were reported during the clinical follow-up period of this study; none of the adverse events registered within the first 72 h after inoculation were life-threatening for volunteers. Neither severe nor moderate adverse events were reported. Sixty-one percent of subjects showed mild expected adverse events in an interval lower than 24h up to the first 72 h, 75% of these in the vaccinated group and 18% in the placebo group. Fourteen days after inoculation the GMT of vibriocidal antibodies in the vaccine group significantly increased in comparison to the placebo group. All subjects in the vaccine group (24) seroconverted (100%). Results show that this vaccine is safe, well tolerated and immunogenic in healthy female and male volunteers.

    Alcohol induces oxidative stress and inflammatory response, which can lead to hepatitis and cirrhosis. Previous studies reported that the extracts of Angelica keiskei Koidzumi (AKE) have antioxidant and anti-inflammatory properties, suggesting that AKE could improve abnormalities associated with alcoholic liver disease. In this study, the effectiveness of AKE supplementation was assessed in 82 habitual alcohol drinkers (male: more than 14 units per week, female: more than 7 units per week) with abnormal liver biochemistry in a placebo-controlled, randomized double-blind trial over 12 weeks. Among the subjects, 65% (n=43) were heavy drinkers consuming more than 35 units per week. Among heavy drinkers, gamma-glutamyl transferase levels of 19 subjects per AKE-treated group were significantly decreased (21.16±37.63, P=.016) with significant differences observed compared to the 24 subjects per placebo group (P=.046). However, no significant differences were observed in aspartate aminotransferase and alanine aminotransferase levels between the AKE- and placebo-treated groups. These results suggest that AKE supplementation might improve liver function in heavy drinkers.

    Management of secondary hyperparathyroidism is challenging with traditional therapy. The calcimimetic cinacalcet HCl acts on the calcium-sensing receptor to increase its sensitivity to calcium, thereby reducing parathyroid hormone (PTH) secretion. This phase 3, multicenter, randomized, placebo-controlled, double-blind study evaluated the efficacy and safety of cinacalcet in hemodialysis (HD) and peritoneal dialysis (PD) patients with PTH > or =300 pg/ml despite traditional therapy. A total of 395 patients received once-daily oral cinacalcet (260 HD, 34 PD) or placebo (89 HD, 12 PD) titrated from 30 to 180 mg to achieve a target intact PTH (iPTH) level of or =30% reduction in iPTH from baseline (65 versus 13%), and proportion of patients with > or =20, > or =40, or > or =50% reduction from baseline. Cinacalcet had comparable efficacy in HD and PD patients; 50% of PD patients achieved a mean iPTH < or =300 pg/ml. Cinacalcet also significantly reduced serum calcium, phosphorus, and Ca x P levels compared with control treatment. The most common side effects, nausea and vomiting, were usually mild to moderate in severity and transient. Once-daily oral cinacalcet was effective in rapidly and safely reducing PTH, Ca x P, calcium, and phosphorus levels in patients who received HD or PD. Cinacalcet offers a new therapeutic option for controlling secondary hyperparathyroidism in patients with chronic kidney disease on dialysis.

    Full Text Available Objective. To evaluate the effects of ezetimibe/simvastatin (EZE/SIMV and rosuvastatin (ROSUV on oxidative stress (OS markers in patients with diabetic polyneuropathy (DPN. Methods. We performed a randomized, double-blind, placebo-controlled phase III clinical trial in adult patients with Type 2 Diabetes Mellitus (T2DM and DPN, as evaluated by composite scores and nerve conduction studies (NCS. Seventy-four subjects with T2DM were allocated 1 : 1 : 1 to placebo, EZE/SIMV 10/20 mg, or ROSUV 20 mg for 16 weeks. All patients were assessed before and after treatment: primary outcomes were lipid peroxidation (LPO, and nitric oxide (NO surrogate levels in plasma; secondary outcomes included NCS, neuropathic symptom scores, and metabolic parameters. Data were expressed as mean ± SD or SEM, frequencies, and percentages; we used nonparametric analysis. Results. LPO levels were reduced in both statin arms after 16 weeks of treatment (p<0.05 versus baseline, without changes in the placebo group. NO levels were not significantly affected by statin treatment, although a trend towards significance concerning increased NO levels was noted in both statin arms. No significant changes were observed for the NCS or composite scores. Discussion. EZE/SIMV and ROSUV are superior to placebo in reducing LPO in subjects with T2DM suffering from polyneuropathy. This trial is registered with NCT02129231.

    We hypothesized that preemptive fibrinogen administration to obtain an initial plasma level of 2.9 g/L would reduce transfusion requirements in liver transplantation. A randomized, multicenter, hemoglobin-stratified, double-blind, fibrinogen-versus-saline-controlled trial was conducted. The primary end point was the percentage of patients requiring red blood cells. We evaluated 51 patients allocated to fibrinogen and 48 allocated to saline; the primary end point was assessed using data for 92 patients because the electronic record forms were offline for three patients in the fibrinogen group and four in the saline group. We injected a median of 3.54 g fibrinogen preemptively in the fibrinogen group. Nine patients in the saline group (20.9%) required fibrinogen at graft reperfusion (compared with one patient [2.1%] in the fibrinogen group; p = 0.005). Blood was transfused to 52.9% (95% confidence interval [CI] 42.5-63.3%) in the fibrinogen group and 42.74% (95% CI 28.3-57.2%) in the saline group (p = 0.217). Relative risk for blood transfusion was 0.80 (95% CI 0.57-1.13). Thrombotic events occurred in one patient (2.1%) and five patients (11.4%) in the fibrinogen and saline groups, respectively. Seven patients (14.6%) in the fibrinogen group and nine (20.3%) in the saline group required reoperation. Preemptive administration of fibrinogen concentrate did not influence transfusion requirements. PMID:26880105

    Background: Rheumatoid arthritis is a symmetric peripheral polyarthritis of unknown etiology that, untreated or if unresponsive the therapy, typically leads to deformity and destruction of joints due to erosion of cartilage and bone. Omega-3 fatty acids have been shown to reduce morning stiffness, the number of tender joints and swollen joints in patients with rheumatoid arthritis. This study is designed for evaluation of omega-3 effects on disease activity and remission of rheumatoid arthritis in DMARDs treated patients and on weight changes and reduction of analgesic drugs consumption versus placebo. Methods: Sixty patients with active rheumatoid arthritis (49 female and 11 male) underwent rheumatologist examination and disease activity score were calculated. Then patients were enrolled in this 12 week, double blind, randomized, placebo- controlled study. The patients in both groups continued their pre study standard treatment. The patients were visited every 4 weeks, 4 times and data were recorded. Results: Significant improvement in the patient’s global evaluation and in the physician’s assessment of disease was observed in those taking omega-3. The proportions of patients who improved and of those who were able to reduce their concomitant analgesic medication were significantly greater with omega-3 consumption. There were no weight changes. Conclusion: Daily supplementation with omega-3 results has significant clinical benefit and may reduce the need for concomitant analgesic consumption without weight changes. PMID:26925896

    Infrared A radiation (IRA) from solar sunlight contributes to photoaging of human skin, e.g. by upregulating MMP-1 expression in dermal fibroblasts, indicating the need for photoprotection of human skin against IRA. Up to now, however, there has been no controlled study to show that effective protection of human skin against IRA radiation is possible. Here, we have conducted a randomized, controlled, double-blinded prospective study in 30 healthy volunteers to assess the capacity of an SPF 30 sunscreen versus the same sunscreen supplemented with an antioxidant cocktail containing grape seed extract, vitamin E, ubiquinone and vitamin C to protect human skin against IRA radiation-induced MMP-1 upregulation. As expected, exposure to IRA radiation significantly upregulated MMP-1 expression, as compared to unirradiated skin, and this response was significantly reduced, if the SPF30 sunscreen plus the antioxidant cocktail had been applied prior to IRA radiation. In contrast, treatment of human skin with the SPF30 sunscreen alone did not provide significant protection. These results indicate that topically applied antioxidants effectively protect human skin against IRA radiation and that regular sunscreens need to be supplemented with specific antioxidants in order to achieve IRA photoprotection.

    Full Text Available Objective: Cancer represents the second cause of mortality in the world. Saffron as a medicinal plant is known for its anti-cancer and anti-depressant properties. In this randomized double blind clinical trial, the effects of saffron on response to treatment in patients suffering from liver metastasis were evaluated. Materials and Methods: Thirteen patients suffering from liver metastases who referred to Ghaem and Imam Reza hospital, Mashhad, Iran were included in this study and then divided into two different groups. Both groups received chemotherapy regimen. Patients in group one were treated with saffron capsule (50 mg, twice daily during chemotherapy periods whereas patients in group two received placebo. A sum of the longest diameter were calculated and compared for all lesions in IV contrast CT scan before and after the treatment. Results: from 13 patients included in this study, six patients quit and seven continued until the end. In saffron-treated group, two patients showed partial and complete response (50% whereas in placebo group, no response was seen. Also, two deaths in placebo and one in saffron group occurred. Conclusion: This research suggests that saffron might be useful in patients suffering from liver metastasis. However, further investigations with larger sample size are required.

    In a double blind study, patients with operable carcinoma of the colon and the upper rectum, who have undergone a macroscopically complete resection of their tumor, were randomized to receive either (i) polyadenylic-polyuridylic acid (AU), one i.v. injection of 60 mg (in 50 ml of solution) once a week for 6 weeks, or (ii) a placebo (P) one i.v. injection of 50 ml of a saline solution with the same schedule. From January 1983 to December 1986, 288 patients were enrolled: 145 in AU group and 143 in P group. The main clinical and pathological characteristics were equally distributed throughout the two groups. There was a significant difference (P < 0.02) in the overall survival (OS) between the two groups, in favor of the P group. The 5-year OS rate was 68% (SD = 4%) in the AU group versus 81% (SD = 3%) in the P group. Thus, AU as a single adjuvant, appears to be ineffective and therefore has no indication in the treatment of colorectal carcinoma. PMID:1478293

    We evaluated the efficacy and safety of gallopamil 150 mg daily in middle-aged and elderly patients with stable exertional ischemia, using a medium-term randomized double-blind cross-over placebo-controlled trial. Twenty middle-aged patients (52.8 +/- 6 years; range 38-61 years) and 14 elderly patients (67.4 +/- 2.8 years; range 65-73 years) with stable exertional ischemia underwent a bicycle exercise test. After a run-in period, both groups received treatment with either placebo or gallopamil 50 mg tid for 28 days. At the end of this time, each patient crossed over to the alternate regimen. Gallopamil significantly reduced heart rate, blood pressure and rate pressure product (from 15.37 +/- 2.7 to 13.65 +/- 4.16 U x 10(-3); p pressure products similar to those reached during placebo at higher work loads. Exercise duration and maximal work load significantly increased in both groups. Electrocardiographic signs of ischemia were favorably influenced by gallopamil in both groups (from 1.39 +/- 0.5 mm to 0.76 +/- 0.73 mm; p < 0.001 in the middle-aged patients and from 1.5 +/- 0.34 mm to 1 +/- 0.76 mm; p < 0.01 in the elderly patients).(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7548266

    Full Text Available Abstract Background Ageing is associated with a significant reduction in skeletal muscle carnosine which has been linked with a reduction in the buffering capacity of muscle and in theory, may increase the rate of fatigue during exercise. Supplementing beta-alanine has been shown to significantly increase skeletal muscle carnosine. The purpose of this study, therefore, was to examine the effects of ninety days of beta-alanine supplementation on the physical working capacity at the fatigue threshold (PWCFT in elderly men and women. Methods Using a double-blind placebo controlled design, twenty-six men (n = 9 and women (n = 17 (age ± SD = 72.8 ± 11.1 yrs were randomly assigned to either beta-alanine (BA: 800 mg × 3 per day; n = 12; CarnoSyn™ or Placebo (PL; n = 14 group. Before (pre and after (post the supplementation period, participants performed a discontinuous cycle ergometry test to determine the PWCFT. Results Significant increases in PWCFT (28.6% from pre- to post-supplementation were found for the BA treatment group (p Conclusion We suggest that BA supplementation, by improving intracellular pH control, improves muscle endurance in the elderly. This, we believe, could have importance in the prevention of falls, and the maintenance of health and independent living in elderly men and women.

    Full Text Available Introduction: For quite a few years, tranexamic acid (TEA has been used during total knee arthroplasty (TKA to reduce blood loss. However, no consensus exits regarding its timing and doses. Materials and Methods: We conducted a prospective, randomized double-blinded study of 56 patients in the Indian population undergoing TKA from 2011 to 2012. A dose of 10 mg/kg body weight of TEA (three doses was given in one group and normal saline was administered in the other. Results: The mean blood loss in the TEA unilateral group was 295 mL ± 218 mL and in the placebo group was 482 mL ± 186 mL (P < 0.005. In the bilateral TEA group, the mean blood loss was 596 mL ± 235 mL and in the placebo group was 1349 mL ± 41 mL (P < 0.005. Conclusion: The number of patients requiring blood transfusion reduced substantially. There was no increase in the risk of deep vein thrombosis (DVT and pulmonary embolism. TEA reduces intraoperative and postoperative blood loss and thus reduces the need of allogenic blood transfusion.

    Full Text Available Background and Objectives. The null hypothesis of this study was that TA has no effect on postsurgical bleeding in patients undergoing TKA. Methods. This study was a double-blind randomized trial. In the first group (T patients received 500 mg of intravenous Tranexamic acid (TA twice (once preoperatively and once 3 hours postoperatively and in the second group (P they received slow infusion of normal saline as placebo. The primary outcome of the study was the level of Hb 48 hours after surgery. Results. Hb levels 48 hours after surgery as the primary outcome were 10.92±0.97 and 10.23±0.98 (g/dL in groups T and P, respectively, and the difference was statistically significant (P=0.001. Statistically significant differences were also observed in Hb levels 6 and 24 hours after surgery, the drain output 48 hours after surgery, and the number of units of packed cells transfused between study groups (P<0.05. There was no significant difference in duration of hospitalization between the study groups (P = n.s.. Conclusions. The low dose perioperative intravenous TA significantly reduces blood loss, requirement for blood transfusion, and drain output in patients undergoing TKA. However, duration of hospitalization did not change significantly.

    In a multicentre, international double-blind trial, patients undergoing courses of five or more daily radiotherapy treatments to the upper abdomen were randomized to receive either oral ondansetron 8 mg t.d.s. or oral prochlorperazine 10 mg t.d.s. throughout their radiation course in order to try to prevent nausea and vomiting. A total of 192 patients were recruited, 135 of whom were included in the efficacy analysis; of these, 70 received ondansetron and 65 prochlorperazine. Forty-three (61%) of the patients prescribed ondansetron and 23 (35%) of those given prochlorperazine had a complete response, with no emetic episodes throughout their treatment course. There was, however, no significant difference between the two groups with respect to the incidence and severity of nausea. Seventeen (24%) of the patients on ondansetron and 19 (29%) of those given prochlorperazine were treatment failures, experiencing more than five emetic episodes on their worst day during the study. Both drugs were well tolerated, although constipation was seen more commonly with ondansetron. (author).

    Background and Aim. The efficacy of supplementation treatment with two multispecies probiotic formulates on subjects diagnosed with IBS-C and the assessment of their gut microbiota were investigated. Methods. A randomized, double-blind, three-arm parallel group trial was carried out on 150 IBS-C subjects divided into three groups (F_1, F_2, and F_3). Each group received a daily oral administration of probiotic mixtures (for 60 days) F_1 or F_2 or placebo F_3, respectively. Fecal microbiological analyses were performed by species-specific qPCR to assess the different amount of probiotics. Results. The percentage of responders for each symptom was higher in the probiotic groups when compared to placebo group during the treatment period (t60) and was maintained quite similar during the follow-up period (t90). Fecal analysis demonstrated that probiotics of the formulations increased during the times of treatment only in fecal DNA from subjects treated with F_1 and F_2 and not with F_3, and the same level was maintained during the follow-up period. Conclusions. Multispecies probiotic supplementations are effective in IBS-C subjects and induce a different assessment in the composition of intestinal microbiota. This clinical study is registered with the clinical study registration number ISRCTN15032219. PMID:27595104

    A total of 121 Japanese patients scheduled for prostate biopsy were randomly and double-blindly assigned to be given a single oral dose of 100 mg Tramadol mixed with 20 ml of sugar syrup or placebo, 30 minutes before the procedure. Pain severity was measured by verbal rating scale (VRS) and visual analog scales (VAS). We also analyzed cardio-respiratory parameters and complications. Of 121 patients, 117 replied validly to VRS and VAS ; and 91 of 117 patients replied to the cohort questionnaire for analysis of the late disorder, patient's impression, prolonged pain and past history of hemorrhoid treatment. Tramadol showed no significant effect on pain severity indicated by VRS and VAS, and no change in cardiorespiratory parameters. Furthermore, 70 patients without a history of hemorrhoid treatment, showed no significant analgesic benefits of Tramadol during the biopsy. In total, 3 patients had side effects of vomiting (CTCAE : grade 1)6), which subsided spontaneously. The oral administration of a single dose of 100 mg Tramadol 30 minutes before a transrectal needle biopsy of the prostate was safe, but was not effective to calm down the pain severity.

    Intercontinental air travel can be stressful, especially for respiratory health. Elderberries have been used traditionally, and in some observational and clinical studies, as supportive agents against the common cold and influenza. This randomized, double-blind placebo-controlled clinical trial of 312 economy class passengers travelling from Australia to an overseas destination aimed to investigate if a standardised membrane filtered elderberry (Sambucus nigra L.) extract has beneficial effects on physical, especially respiratory, and mental health. Cold episodes, cold duration and symptoms were noted in a daily diary and assessed using the Jackson score. Participants also completed three surveys containing questions regarding upper respiratory symptoms (WURSS-21) and quality of life (SF-12) at baseline, just before travel and at 4-days after travel. Most cold episodes occurred in the placebo group (17 vs. 12), however the difference was not significant (p = 0.4). Placebo group participants had a significantly longer duration of cold episode days (117 vs. 57, p = 0.02) and the average symptom score over these days was also significantly higher (583 vs. 247, p = 0.05). These data suggest a significant reduction of cold duration and severity in air travelers. More research is warranted to confirm this effect and to evaluate elderberry's physical and mental health benefits. PMID:27023596

    The aim of this study was to analyze the effects of 8 weeks of conjugated linoleic acid (CLA) supplementation associated with aerobic exercise on body fat and lipid profile on obese women. We performed a randomized, double-blinded and placebo-controlled trial with 28 obese women who received 3.2 g/day of CLA or 4 g/day of olive oil (placebo group) while performing an 8-week protocol of aerobic exercise. Dietary intake (food record), body fat (dual-energy X-ray absorptiometry), and biochemical analysis (blood sample) were assessed before and after the intervention period. Independent of CLA supplementation, both groups improved (p CLA group, 13.2%; PLC group, 14.8%), trunk fat (CLA group, -1.0%; PLC group, -0.5%), leg fat (CLA group, -1.0%; PLC group, -1.6%), and total body fat (CLA group, -1.7%; PLC group, -1.3%) after the 8-week intervention. No main effect or Group × Time interaction was found for total cholesterol, triglycerides, and plasma lipoproteins (p > .05). We conclude that CLA supplementation associated with aerobic exercise has no effect on body fat reduction and lipid profile improvements over placebo in young adult obese women. PMID:26402730

    Vaginal dryness is a common problem for which effective and safe nonestrogenic treatments are needed. Based on preliminary promising data that pilocarpine attenuated vaginal dryness, the current trial was conducted. A double-blind, placebo-controlled, randomized trial design was used to compare pilocarpine, at target doses of 5 mg twice daily and 5 mg four times daily, with a placebo. Vaginal dryness was recorded by patient-completed questionnaires at baseline and weekly for 6 weeks after study initiation. The primary endpoint for this study was the area under the curve summary statistic composed of the longitudinal responses obtained at baseline and through the 6 weeks of treatment to a numerical analogue scale asking patients to rate their perceived amount of vaginal dryness. The primary analysis was carried out by a single t test using a two-side alternative to compare the collective pilocarpine treatment arms with the collective placebo arms. A total of 201 patients enrolled in this trial. The primary analysis, comparing vaginal dryness symptoms in the collective pilocarpine arms against the placebo arm, did not reveal any benefit for the pilocarpine treatment. This finding was confirmed by other secondary analyses. Toxicity evaluation revealed more nausea, sweating, rigors, and urinary frequency with the pilocarpine arms compared with the placebo arm.

    Full Text Available Abstract Background Multilevel spinal fusion surgery has typically been associated with significant blood loss. To limit both the need for transfusions and co-morbidities associated with blood loss, the use of anti-fibrinolytic agents has been proposed. While there is some literature comparing the effectiveness of tranexamic acid (TXA to epsilon aminocaproic acid (EACA in cardiac procedures, there is currently no literature directly comparing TXA to EACA in orthopedic surgery. Methods/Design Here we propose a prospective, randomized, double-blinded control study evaluating the effects of TXA, EACA, and placebo for treatment of adolescent idiopathic scoliosis (AIS, neuromuscular scoliosis (NMS, and adult deformity (AD via corrective spinal surgery. Efficacy will be determined by intraoperative and postoperative blood loss. Other clinical outcomes that will be compared include transfusion rates, preoperative and postoperative hemodynamic values, and length of hospital stay after the procedure. Discussion The primary goal of the study is to determine perioperative blood loss as a measure of the efficacy of TXA, EACA, and placebo. Based on current literature and the mechanism by which the medications act, we hypothesize that TXA will be more effective at reducing blood loss than EACA or placebo and result in improved patient outcomes.

    Work-related stress (WS) can result in considerable and extensive changes in physiological and psychological performance. WS beyond the optimal levels induces anxiety, confusion, exhaustion, and burnout. Chronic WS affects neurocognitive performance, particularly attention and visuospatial memory. Essence of chicken (EC) has been reported to improve neurocognitive function after mental stress.To investigate the beneficial effects of EC in improving neurocognitive performance under WS, we conducted a randomized, double blind trial. Total 102 young workers in New Taipei City with high WS, evaluated using the Individual Subjective Perception Job Stress Scale scores (>36 for job leaders and 33 for nonleaders) were recruited. Fifty-one participants received 70 mL of EC and 51 received a placebo daily for 2 weeks. Blood tests and neurocognitive assessment were performed before treatment, at the end of treatment, and 2 weeks after treatment.EC improved the performance of participants with high depression scores in the form-color associative memory test, used for assessing short-term memory. Although creatinine and glutamic-pyruvic transaminase (GPT) levels increased in week 2, but the levels returned to the baseline in week 4. Blood urea nitrogen (BUN) levels decreased in week 4.EC significantly improved short-term memory in participants with high WS and concomitant depressive mood, although it slightly increased GPT and creatinine levels and reduced BUN levels. The long-term treatment effects of EC warrant further investigation. PMID:27175681

    The anxiolytic efficacy of the orally administered lavender oil preparation Silexan was investigated in generalized anxiety disorder (GAD) in comparison to placebo and paroxetine. In this randomized, double-blind, double-dummy trial 539 adults with GAD according to DSM-5 criteria and a Hamilton Anxiety Scale (HAMA) total score ⩾ 18 points participated and received 160 or 80 mg Silexan, 20 mg paroxetine, or placebo once daily for 10 wk. The primary efficacy endpoint was the HAMA total score reduction between baseline and treatment end. The HAMA total score decreased by 14.1 ± 9.3 points for Silexan 160 mg/d, 12.8 ± 8.7 points for Silexan 80 mg/d, 11.3 ± 8.0 points for paroxetine, and 9.5 ± 9.0 points for placebo (mean ± s.d.). Silexan 160 and 80 mg/d were superior to placebo in reducing the HAMA total score (p mental health and health-related quality of life. Incidence densities of adverse events (AEs) were 0.006 AEs/d for Silexan 160 mg/d, 0.008 AEs/d for 80 mg/d, 0.011 AEs/d for paroxetine, and 0.008 AEs/d for placebo. In GAD Silexan is more efficacious than placebo. AE rates for Silexan were comparable to placebo and lower than for the active control paroxetine.

    The objective was to determine whether a cannabis-based medicinal extract (CBME) benefits a range of symptoms due to multiple sclerosis (MS). A parallel group, double-blind, randomized, placebo-controlled study was undertaken in three centres, recruiting 160 outpatients with MS experiencing significant problems from at least one of the following: spasticity, spasms, bladder problems, tremor or pain. The interventions were oromucosal sprays of matched placebo, or whole plant CBME containing equal amounts of delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) at a dose of 2.5-120 mg of each daily, in divided doses. The primary outcome measure was a Visual Analogue Scale (VAS) score for each patient's most troublesome symptom. Additional measures included VAS scores of other symptoms, and measures of disability, cognition, mood, sleep and fatigue. Following CBME the primary symptom score reduced from mean (SE) 74.36 (11.1) to 48.89 (22.0) following CBME and from 74.31 (12.5) to 54.79 (26.3) following placebo [ns]. Spasticity VAS scores were significantly reduced by CBME (Sativex) in comparison with placebo (P =0.001). There were no significant adverse effects on cognition or mood and intoxication was generally mild. PMID:15327042

    Full Text Available OBJECTIVE: To assess the effects of carvedilol in patients with idiopathic dilated cardiomyopathy. METHODS: In a double-blind randomized placebo-controlled study, 30 patients (7 women with functional class II and III heart failure were assessed. Their ages ranged from 28 to 66 years (mean of 43±9 years, and their left ventricular ejection fraction varied from 8% to 35%. Carvedilol was added to the usual therapy of 20 patients; placebo was added to the usual therapy of 10 patients. The initial dose of carvedilol was 12.5 mg, which was increased weekly until it reached 75 mg/day, according to the patient's tolerance. Clinical assessment, electrocardiogram, echocardiogram, and radionuclide ventriculography were performed in the pretreatment phase, being repeated after 2 and 6 months of medication use. RESULTS: A reduction in heart rate (p=0.016 as well as an increase in left ventricular shortening fraction (p=0.02 and in left ventricular ejection fraction (p=0.017 occurred in the group using carvedilol as compared with that using placebo. CONCLUSION: Carvedilol added to the usual therapy for heart failure resulted in better heart function.

    Full Text Available Abstract Background There are no published studies that have compared bronchodilatory effect of inhaled budesonide/formoterol combination with budesonide/salbutamol delivered by metered dose inhaler with a spacer in acute exacerbation of asthma in children. We, therefore, compared the bronchodilatory effects of inhaled budesonide/formoterol (dose: 200 μg and 12 μg respectively combination with budesonide (200 μg/salbutamol (200 μg administered by metered dose inhaler and spacer in children of 5-15 years with mild acute exacerbation of asthma [Modified Pulmonary Index Score (MPIS between 6-8] in this double-blind, randomized controlled trial. The primary outcome was FEV1 (% predicted in the two groups at 1, 5, 15, 30, 60 min after administration of the study drug. Results We did not observe any significant differences in the % predicted FEV1 and MPIS between formoterol and salbutamol at various time points from 1 min to 60 min post drug administration. There was significant improvement in FEV1 (% predicted from baseline in both the groups as early as 1 min after drug administration. Conclusions Salbutamol or formoterol delivered along with inhaled corticosteroid by metered dose inhaler with spacer in children between 5-15 years of age with mild acute exacerbation of asthma had similar bronchodilatory effects.

    Full Text Available Infrared (IR therapy is used for pain relief in patients with knee osteoarthritis (OA. However, IR’s effects on the cardiovascular system remain uncertain. Therefore, we investigated the local and systemic cardiovascular effects of monochromatic IR therapy on patients with knee OA in a double-blind, randomized, placebo-controlled study. Seventy-one subjects with knee OA received one session of 40 min of active or placebo monochromatic IR treatment (with power output of 6.24 W, wavelength of 890 nm, power density of 34.7 mW/cm2 for 40 min, total energy of 41.6 J/cm2 per knee per session over the knee joints. Heart rate, blood pressure, and knee arterial blood flow velocity were periodically assessed at the baseline, during, and after treatment. Data were analyzed by repeated-measure analysis of covariance. Compared to baseline, there were no statistically significant group x time interaction effects between the 2 groups for heart rate (P=0.160, blood pressure (systolic blood pressure: P=0.861; diastolic blood pressure: P=0.757, or mean arterial blood flow velocity (P=0.769 in follow-up assessments. The present study revealed that although there was no increase of knee arterial blood flow velocity, monochromatic IR therapy produced no detrimental systemic cardiovascular effects.

    The objective of this study was to evaluate the efficacy, safety and tolerability of brexpiprazole versus placebo in adults with acute schizophrenia. This was a 6-week, multicenter, placebo-controlled double-blind phase 3 study. Patients with acute schizophrenia were randomized to brexpiprazole 1, 2 or 4 mg, or placebo (2:3:3:3) once daily. The primary endpoint was changed from baseline at week 6 in Positive and Negative Syndrome Scale (PANSS) total score; the key secondary endpoint was Clinical Global Impressions-Severity (CGI-S) at week 6. Brexpiprazole 4 mg showed statistically significant improvement versus placebo (treatment difference: -6.47, p=0.0022) for the primary endpoint. Improvement compared with placebo was also seen for the key secondary endpoint (treatment difference: -0.38, p=0.0015), and on multiple secondary efficacy outcomes. Brexpiprazole 1 and 2mg also showed numerical improvements versus placebo, although p>0.05. The most common treatment-emergent adverse events were headache, insomnia and agitation; incidences of akathisia were lower in the brexpiprazole treatment groups (4.2%-6.5%) versus placebo (7.1%). Brexpiprazole treatment was associated with moderate weight gain at week 6 (1.23-1.89 kg versus 0.35 kg for placebo); there were no clinically relevant changes in laboratory parameters and vital signs. In conclusion, brexpiprazole 4 mg is an efficacious and well-tolerated treatment for acute schizophrenia in adults. Clinical Trials.gov NCT01393613; BEACON trial.

    Full Text Available A randomized, double-blind, placebo-controlled study was conducted to evaluate the efficacy of GutGard, an extract of Glycyrrhiza glabra, in patients with functional dyspepsia. The primary outcome variables of the study were the change in the severity symptoms and the global assessment of efficacy. The quality of life was evaluated as a secondary outcome measure. The patients received either placebo or GutGard (75 mg twice daily for 30 days. Efficacy was evaluated in terms of change in the severity of symptoms (as measured by 7-point Likert scale, the global assessment of efficacy, and the assessment of quality of life using the short-form Nepean Dyspepsia Index. In comparison with placebo, GutGard showed a significant decrease (P≤.05 in total symptom scores on day 15 and day 30, respectively. Similarly, GutGard showed marked improvement in the global assessment of efficacy in comparison to the placebo. The GutGard group also showed a significant decrease (P≤.05 in the Nepean dyspepsia index on day 15 and 30, respectively, when compared to placebo. GutGard was generally found to be safe and well-tolerated by all patients. GutGard has shown significant efficacy in the management of functional dyspepsia.

  19. Randomized, double-blind, controlled, comparative trial of formula food containing soy protein vs. milk protein in visceral fat obesity. FLAVO study

    International Nuclear Information System (INIS)

    The purpose of the present study was to clarify the efficacy of soy at reducing visceral fat. A randomized, double-blind, controlled, comparative trial was carried out to compare formula food containing soy protein (SP) to the same food in which soy was replaced with milk protein (MP). Forty-eight participants were enrolled for the treatment of visceral fat obesity (visceral fat area >100 cm2 on computed tomography). The SP formula contained 12 g of SP, 9 g of MP, and other nutrients, and was given for 20 weeks in the morning, while in the MP formula SP was replaced with MP. During the 20 weeks of the trial period, visceral fat area and subcutaneous fat area in the MP group were significantly reduced, while those in the SP group did not change as assessed on analysis of covariance. Although waist circumference was reduced in both the SP and MP groups, body weight and body mass index were significantly reduced only in the MP group. Based on a mixed-effects model, the difference in log-transformed visceral fat profiles between the 2 groups was statistically significant (P<0.05), while a negative relationship was observed between the changes in visceral fat and adiponectin in the MP group (P<0.001), but not in the SP group. Formula food containing MP is superior to that containing SP for reducing visceral and subcutaneous fat. (author)

  20. Zinc supplementation to improve mucositis and dermatitis in patients after radiotherapy for head-and-neck cancers: A double-blind, randomized study

    International Nuclear Information System (INIS)

    Purpose: To determine whether zinc supplementation can accelerate the healing of mucositis and dermatitis after radiotherapy. Methods and Materials: In this double-blind study, patients were placed into two randomized groups (experimental and control) of 50 patients each. The groups were homogeneous with respect to medical history, tumor characteristics, and therapeutic details. The experimental group received a standard dose of a zinc supplement, and the control group was given a placebo. Results: Patients in the control group developed Grade 2 mucositis and dermatitis earlier and sooner than patients in the experimental group. There was also a significant difference in the development of Grade 3 mucositis and dermatitis between the two groups. Patients in the experimental group were found to have milder mucositis and dermatitis. Zinc supplementation did not show much benefit in those patients receiving concurrent chemotherapy or make a substantial impact on weight changes. Conclusions: Zinc supplementation used in conjunction with radiotherapy could postpone the development of severe mucositis and dermatitis for patients with cancers of the head and neck. Zinc supplementation can also alleviate the degree of mucositis and dermatitis. The impact of zinc on tumor growth and patient survival is under further investigation

    In Cambodia, micronutrient deficiencies remain a critical public health problem. Our objective was to evaluate the impact of multi-micronutrient fortified rice (MMFR) formulations, distributed through a World Food Program school-meals program (WFP-SMP), on the hemoglobin concentrations and iron and vitamin A (VA) status of Cambodian schoolchildren. The FORISCA-UltraRice+NutriRice study was a double-blind, cluster-randomized, placebo-controlled trial. Sixteen schools participating in WFP-SMP were randomly assigned to receive extrusion-fortified rice (UltraRice Original, UltraRice New (URN), or NutriRice) or unfortified rice (placebo) six days a week for six months. Four additional schools not participating in WFP-SMP were randomly selected as controls. A total of 2440 schoolchildren (6-16 years old) participated in the biochemical study. Hemoglobin, iron status, estimated using inflammation-adjusted ferritin and transferrin receptors concentrations, and VA status, assessed using inflammation-adjusted retinol-binding protein concentration, were measured at the baseline, as well as at three and six months. Baseline prevalence of anemia, depleted iron stores, tissue iron deficiency, marginal VA status and VA deficiency were 15.6%, 1.4%, 51.0%, 7.9%, and 0.7%, respectively. The strongest risk factors for anemia were hemoglobinopathy, VA deficiency, and depleted iron stores (all p status, respectively, in comparison to the placebo group. Hemoglobin significantly increased (+0.8 g/L) after three months for the URN group in comparison to the placebo group; however, this difference was no longer significant after six months, except for children without inflammation. MMFR containing VA effectively improved the VA status of schoolchildren. The impact on hemoglobin and iron status was limited, partly by sub-clinical inflammation. MMFR combined with non-nutritional approaches addressing anemia and inflammation should be further investigated.

    Objective The main objective of this study was to evaluate whether vaginal administration of probiotic Lactobacillus results in their colonization and persistence in the vagina and whether Lactobacillus colonization promotes normalization and maintenance of pH and Nugent score. Patients and methods The study was a multicenter, randomized, double-blind, and placebo-controlled trial. Altogether, 376 women were assessed for eligibility, and signed informed consent. One hundred and sixty eligible women with abnormal, also called intermediate, vaginal microflora, as indicated by a Nugent score of 4–6 and pH >4.5 and zero or low Lactobacillus count, were randomized. Each participant was examined four times during the study. Women were randomly allocated to receive either the probiotic preparation inVag®, or a placebo (one capsule for seven consecutive days vaginally). The product inVag includes the probiotic strains Lactobacillus fermentum 57A, Lactobacillus plantarum 57B, and Lactobacillus gasseri 57C. We took vaginal swabs during visits I, III, and IV to determine the presence and abundance of bacteria from the Lactobacillus genus, measure the pH, and estimate the Nugent score. Drug safety evaluation was based on analysis of the types and occurrence of adverse events. Results Administration of inVag contributed to a significant decrease (between visits) in both vaginal pH (PLactobacillus between visit I and visits III and IV (PLactobacillus strains originating from inVag in 82% of women taking the drug at visit III, and 47.5% at visit IV. There was no serious adverse event related to inVag administration during the study. Conclusion The probiotic inVag is safe for administration to sustainably restore the healthy vaginal microbiota, as demonstrated by predominance of the Lactobacillus bacteria in vaginal microbiota.

    Full Text Available Background: Chronic urticaria not responsive to antihistamines is a difficult disease to manage. Methotrexate has been used in difficult chronic urticarias with some benefit. Objective: To evaluate the efficacy of methotrexate in the treatment of chronic spontaneous urticaria poorly responsive to H1 antihistaminics. Methods: In a randomized double-blind trial at the Department of Dermatology and Venereology of a tertiary care centre, 29 patients with chronic spontaneous urticaria not responding well to H1 antihistaminics were recruited. Patients were randomly allocated to receive either a weekly dose of oral methotrexate 15 mg or placebo (calcium carbonate for a total duration of 12 weeks, after which treatment was stopped and patients were followed up for relapse of urticaria. Each group also received levocetrizine 5 mg once daily for symptom control. Primary outcome measured was a reduction by >2/3 rd of baseline urticaria scores after 12 week therapy. Secondary outcome was a reduction in antihistamine requirement after stopping therapy. Results: Fourteen patients were randomized to the methotrexate group and fifteen patients to the placebo group. Out of 17 patients who completed therapy, the primary outcome was achieved by 3.5 ± 1.9 (out of 10 patients in the methotrexate group and by 3.67 ± 1.03 (out of 7 patients in the placebo group (P > 0.05. Ten patients followed up, after stopping therapy, for a mean period of 3.5 ± 2.4 months; 3 remained in remission and 7 had relapsed. One patient had uncontrollable nausea and vomiting after taking methotrexate and was withdrawn from the study. The placebo group did not experience any side effects. Conclusions: Methotrexate 15 mg weekly for 3 months did not provide any additional benefit over H1 antihistamines in this study but an adequately powered study with longer follow up is required to assess its utility.

    To evaluate the efficacy and safety of mirtazapine in Japanese patients with fibromyalgia (FM), a parallel-group, randomized, double-blind, placebo-controlled phase IIa study was conducted at 57 sites between November 2012 and February 2014. Patients aged 20 to 64 years who met the American College of Rheumatology 1990 diagnostic FM criteria and had stably high pain scores during a placebo run-in period were randomly assigned (1:1) by a computer-generated allocation sequence (block size 4) to receive mirtazapine orally (15 mg/d for 1 week and then 30 mg/d) or matching placebo for 12 weeks. The primary endpoint was change in mean numerical rating scale (NRS) pain score from baseline to endpoint (week 12 or early discontinuation). Of the 430 patients randomized (n = 215 each group), 422 (n = 211 each group) were analyzed for the primary endpoint. At the study endpoint, mirtazapine caused a significantly greater reduction in the mean NRS pain score compared with placebo (difference, 0.44; 95% confidence interval, -0.72 to -0.17; P = 0.0018). The reduction by mirtazapine remained significantly greater compared with placebo from week 6 onward. More patients treated with mirtazapine had their NRS pain score reduced by ≥30% from baseline (45.5% vs 30.8%). Mirtazapine also improved pain-related quality of life assessed by the Japanese version of the Fibromyalgia Impact Questionnaire and the Short-Form 36 Questionnaire. Adverse events were more common with mirtazapine than placebo (68.8% vs 56.7%), including somnolence (32.1% vs 7.4%), weight gain (17.7% vs 0.9%), and increased appetite (11.6% vs 3.3%). In conclusion, mirtazapine was an effective and safe treatment for Japanese patients with FM.

    Full Text Available OBJECTIVES: Anemia is a common complication among chronic kidney disease patients on hemodialysis, occurring mostly due to erythropoietin deficiency. This randomized noninferiority trial sought to compare the efficacy and safety of a new epoetin formulation developed by Bio-Manguinhos, a biologics manufacturer affiliated with the Brazilian government, with those of a commercially available product currently used in Brazil (a biosimilar epoetin formulation. METHODS: The sample size needed to enable demonstration of noninferiority with a statistical power of 85% for a between-group difference in hemoglobin levels of no more than 1.5 g/dL was calculated. In total, 74 patients were randomly assigned to receive the epoetin formulation from Bio-Manguinhos (n = 36 or the biosimilar epoetin formulation (n = 38 in a double-blind fashion. The inclusion criteria were current epoetin therapy and stable hemoglobin levels for at least 3 months prior to the study. The primary and secondary outcomes were mean monthly hemoglobin levels and safety, respectively. The dose was calculated according to international criteria and adjusted monthly in both groups according to hemoglobin levels and at the assistant physicians' discretion. Iron storage was estimated at baseline and once monthly. Clinicaltrials.gov: NCT01184495. RESULTS: The study was conducted for 6 months after randomization. The mean baseline hemoglobin levels were 10.9±1.2 and 10.96±1.2 g/dL (p = 0.89 in the Bio-Manguinhos epoetin and biosimilar epoetin groups, respectively. During the study period, there was no significant change in hemoglobin levels in either group (p = 0.055, ANOVA. The epoetin from Bio-Manguinhos was slightly superior in the last 3 months of follow-up. The adverse event profiles of the two formulations were also similar. CONCLUSIONS: The epoetin formulations tested in this study are equivalent in efficacy and safety.

    Background. Sleep disturbances and cognitive dysfunction are common in patients with breast cancer. Disturbed sleep leads to poor cognitive performance and exogenous melatonin may improve sleep and attenuate cognitive dysfunction. We hypothesized that melatonin would improve sleep and cognitive function after surgery. Methods. This study reports secondary endpoints from a randomized, double-blind, placebo-controlled trial. Women, 30-75 years, were randomized to 6mg oral melatonin/placebo for 3 months. We assessed postoperative cognitive dysfunction (POCD) with a neuropsychological test battery, sleep with a diary, and sleep quality with VAS. Results. 54 patients were randomized to melatonin (n = 28) or placebo (n = 26); 11 withdrew (10 placebo, 1 melatonin, P = 0.002). The incidence of POCD was 0% (0/20) [95% CI 0.0%; 16.8%] in the placebo group and 0% (0/26) [95% CI 0.0%; 13.2%] in the melatonin group 2 weeks postoperatively (P = 1.00) and 6.3% (1/16) [95% CI 0.0%; 30.2%] in the placebo group and 0% (0/26) [95% CI 0.0%; 13.2%] in the melatonin group 12 weeks postoperatively (P = 0.38). Sleep efficiency was significantly greater in the melatonin group; mean difference was 4.28% [95% CI 0.57; 7.82] (P = 0.02). The total sleep period was significantly longer in the melatonin group; mean difference was 37.0 min [95% CI 3.6; 69.7] (P = 0.03). Conclusion. Melatonin increased sleep efficiency and total sleep time but did not affect cognitive function. The dropout rate was significantly lower in the melatonin group.

    Full Text Available Abstract Background Progestational agents may reduce the risk of preterm birth in women with various risk factors. We sought to test the hypothesis that a weekly dose of 17-hydroxyprogesterone caproate (17P given to women with preterm rupture of the membranes (PROM will prolong pregnancy and thereby reduce neonatal morbidity. Methods Double-blind, placebo-controlled randomized clinical trial. Women with PROM at 23.0 to 31.9 weeks of gestation were randomly assigned to receive a weekly intramuscular injection of 17P (250 mg in 1 mL castor oil or placebo (1 mL castor oil. The primary outcome was the rate of continuing the pregnancy until 34.0 weeks of gestation or until documentation of fetal lung maturity at 32.0 to 33.9 weeks of gestation. Planned secondary outcomes were duration of latency period and rate of composite neonatal morbidity. Enrollment of 111 participants per group, 222 total, was planned to yield 80% power to detect an increase in the primary outcome from 30% with placebo to 50% with 17P. Results Twelve women were enrolled of whom 4 were randomly assigned to receive 17P and 8 to receive placebo. The trial was terminated prematurely because of two separate issues related to the supply of 17P. No adverse events attributable to 17P were identified. Conclusion Because of premature termination, the trial does not have adequate statistical power to evaluate efficacy or safety of 17P in women with PROM. Nonetheless, ethical principles dictate that we report the results, which may contribute to possible future metaanalyses and systematic reviews.

Studies of ciprofloxacin as single agent prophylaxis vary widely in success rate. We conducted a double-blind, randomized study to test the effects of ciprofloxacin monotherapy as prophylaxis for sepsis and death in induction treatment of the Indonesian childhood ALL protocol.Methods: Patients were randomized to the ciprofloxacin arm (n = 58 and to the placebo arm (n = 52. Oral ciprofloxacin monotherapy or oral placebo was administered twice a day. All events during induction were recorded: toxic death, abandonment, resistant disease, and complete remission rate.Results: Of 110 patients enrolled in this study, 79 (71.8% achieved CR. In comparison to the placebo arm, the ciprofloxacin arm had lower nadir of absolute neutrophil count during induction with median of 62 (range: 5–884 versus 270 (range: 14–25,480 × 109 cells/L (P > 0.01, greater risks for experiencing fever (50.0% versus 32.7%, P = 0.07, clinical sepsis (50.0% versus 38.5%, P = 0.22, and death (18.9% versus 5.8%, P = 0.05.Conclusion: In our setting, a reduced intensity protocol in a low-income situation, the data warn against using ciprofloxacin prophylaxis during induction treatment. A lower nadir of neutrophil count and higher mortality were found in the ciprofloxacin group.Keywords: ciprofloxacin, prophylaxis, childhood acute lymphoblastic leukemia, randomized trial, low-income country

    Full Text Available Abstract Background Hepatic encephalopathy (HE is a severe complication in patients with hepatic cirrhosis, which causes numerous hospital admissions and deaths. Antibiotics are the best options in HE treatment, but head-to-head comparisons between these drugs are scarce. Erythromycin combines the antimicrobial effect and prokinetic properties in the same drug, but it has never been used in HE treatment. Our aim was to evaluate the efficacy of erythromycin as an HE treatment. Methods We achieved a randomized controlled trial of adult patients with HE and hepatic cirrhosis admitted in our hospital. After randomization, the subjects received either erythromycin 250 mg or neomycin 1 g orally QID until hospital discharge or prescription of another antibiotic. All subjects were blindly evaluated every day towards quantifying clinical, neuropsychometric, hepatic and renal exams. Statistical analysis was employed to compare the groups and correlate the variables with hospitalization duration. Results 30 patients were evaluated (15 treated with each drug. At hospital admission, the groups were homogeneous, but the erythromycin group subjects achieved a shorter hospitalization stay (p = 0.032 and a more expressive reduction in alanine aminotranspherase levels (p = 0.026. Hospitalization duration was positively correlated with C reactive protein levels measured previous to (p = 0.015 and after treatment (p = 0.01. Conclusions In the sample evaluated erythromycin was associated with significant reductions in hospital stay and in alanine aminotranspherase values. Hospitalization time was positive correlated with C reactive protein levels measured before and after the treatments.

    Full Text Available This randomized clinical trial aimed to assess the efficacy of phlebotomy on improvement of hearing loss. 71 patients with sudden sensorineural hearing loss were enrolled in this randomized clinical trial study. They were divided into two groups: group A received steroid and hydration therapy plus phlebotomy, while group B received the same regimen without phlebotomy. They were matched according to sex, age, Hb, and Htc. Pure tone audiometries were administered to examine the hearing levels before and after treatment. Statistical analysis showed higher improvement in 250-1000 Hz in patients whit phlebotomy (P<0.001. However, there was noticed no significant difference in hearing improvement in 2000-8000 Hz between two methods. The number (% of patients who had improvement was 29(85.3% in phlebotomy group and 21(56.8% in non-phlebotomy group. On the other hand, the number (% of patients who showed no improvement in A and B group was 5(14.7% and 16(43.2%, respectively (P=0.008. Using phlebotomy accompanied by steroid and hydration therapy leads to higher improvement in hearing loss especially in 250-1000 Hz. We think that this method has the ability to achieve better result in the management of patients with SSNHL.

    Acute mountain sickness (AMS) is a common and disabling condition that occurs in healthy individuals ascending to high altitude. Based on the ability of iron to influence cellular oxygen sensing pathways, we hypothesized that iron supplementation would protect against AMS. To examine this hypothesis, 24 healthy sea-level residents were randomized to receive either intravenous iron(III)-hydroxide sucrose (200 mg) or saline placebo, before ascending rapidly to Cerro de Pasco, Peru (4340 m). The Lake Louise scoring system was used to assess incidence and severity of AMS at sea level and on the first full day at altitude. No significant difference in absolute AMS score was detected between the two groups either at baseline or at high altitude. However, the mean increase in AMS score was 65% smaller in the iron group than in the saline group (pvolunteers.

    Non-hemolytic transfusion reactions (NHTR) occur in up to 30% of patients receiving platelet transfusions. Premedication with acetaminophen and diphenhydramine is a common strategy to prevent NHTR, but its efficacy has not been studied. In this prospective trial, transfusions in patients receiving pre-storage leukocyte-reduced single-donor apheresis platelets (SDP) were randomized to premedication with either acetaminophen 650 mg PO and diphenhydramine 25 mg IV, or placebo. Fifty-one patients received 98 transfusions. Thirteen patients had 15 NHTR: 15.4% (8/52) in the treatment arm and 15.2% (7/46) in the placebo arm. Premedication prior to transfusion of pre-storage leukocyte reduced SDP does not significantly lower the incidence of NHTR as compared to placebo. PMID:12111764

    Full Text Available Cephalic allodynia (CA can be observed in 50-70% of patients with chronic migraine (CM. The aim of this trial was to assess the efficacy of botulinum toxin type A (Botx-A in the treatment of CA associated with CM. In this placebo-controlled trial, patients were randomized either into Botx-A or 0.9% saline injections and efficacy measures were assessed every 4 weeks for 3 months. Efficacy endpoints were number of migraine episodes associated with CA, changes from baseline in visual analogical scale scores for pain (VAS and frequency of common analgesics use for migraine. A total of 38 subjects were randomized to saline (n=18 or Botx-A (n=20. There were no significant differences in baseline between active intervention or placebo groups regarding mean age, number of headache episodes [mean 12.1 (9.22 and 17.00 (9.69 respectively; P=0.12], pain severity as measured by the VAS or frequency of analgesic use for headache episodes. Efficacy analysis showed that Botx-A injections led to an important decrease from baseline in the mean migraine episodes associated with CA after 12 weeks (5.20 versus 11.17; P=0.01. Also, VAS scores and frequency of analgesics use for headache were significantly reduced in the Botx-A group. This study suggests that Botx-A injections are superior to saline in the treatment of CA associated with CM, with mild self limited side effects.

    Full Text Available Background: Posttraumatic stress disorder (PTSD tends to follow a chronic and treatment resistant course. Avoidance and numbing are symptoms associated with chronicity and impaired life quality. As D-cycloserine (DCS can facilitate extinction of conditioned fear, we aimed to investigate the efficacy and tolerability of DCS for the treatment of numbing and avoidance in chronic PTSD. Materials and Methods: This was an 11-week, double-blind, cross-over trial conducted in 2012 and 2013, in out-patient University psychiatry clinics. The studied population was selected randomly among outpatients with chronic combat-related PTSD (based on DSM-IV-TR criteria for chronic PTSD, who were males over 18 and <65 years of age (n = 319. Seventy six eligible patients were randomly assigned to two groups. Patients entered a 1-week run-in period. The groups received either an add-on treatment of DCS (50 mg daily, or placebo (4-week. After a 2-week washout, the groups received cross-over treatments (4-week. Clinical, paraclinical assessments, and clinician administered PTSD scale (CAPS were performed at baseline, and at the end of the 1 st , 5 th , and 11 th week. Side-effects were also evaluated. The overall number of avoidance and numbing symptoms, symptom frequency, and symptom intensity were measured separately. Results: Neither frequency nor number of symptoms was significantly influenced. However, DCS treatment demonstrates a significant decrease in intensity of avoidance/numbing symptoms, and improvement in function (mean [standard error] = −4.2 [1.5], P = 0.008. Side-effects were not statistically remarkable. Conclusion: D-cycloserine can help as an adjunctive treatment to alleviate numbing and avoidance in combat-related chronic PTSD.

    Full Text Available Background: Post-operative pain frequently hampers implementation of day care arthroscopic knee surgery in spite of so many analgesic, local anesthetic drugs and routes of administration. Aims: The aim of the present study was carried out to compare the efficacy of ropivacaine and levobupivacaine when administered through intra-articular route in controlling pain after day care arthroscopic knee surgery. Setting and Design: It was a prospective, double-blinded and randomized controlled study. Materials and Methods: April 2008-December 2008, 60 patients of both sex, of American Society of Anesthesiologists physical status I and II, undergoing day care arthroscopic knee surgery were randomly assigned into two groups (R, L. Group R received 10 ml of 0.75% ropivacaine, whereas group L received 10 ml of 0.50% levobupivacaine through intra-articular route at the end of the procedure. Pain assessed using visual analog scale (VAS and diclofenac sodium given as rescue analgesia when VAS >3. Time of first analgesic request and total rescue analgesic were calculated. Statistical Analysis and Results: based on comparable demographic profiles; time for the requirement of first post-operative rescue analgesia (242.16 ± 23.86 vs. 366.62 ± 24.42 min and total mean rescue analgesic requirement was (104.35 ± 18.96 vs. 76.82 ± 14.28 mg in group R and L respectively. Group R had higher mean VAS score throughout the study period. No side effects found among the groups. These two results were clinically and statistically significant (P < 0.05. Conclusion: Hence, it was evident that intra-articular levobupivacaine give better post-operative pain relief, with an increase in time of first analgesic request and decreased need of total post-operative analgesia compared with ropivacaine.

    Full Text Available Danshen is the dried root extract of the plant Salvia Miltiorrhiza and it is used as traditional Chinese medicinal herbal product to prevent and treat atherosclerosis. However, its efficacy has not been thoroughly investigated. This study evaluates the effect of Danshen on hyperlipidemia and hypertension, two well known risk factors for the development of atherosclerosis.This was a randomized, placebo-controlled, double-blind crossover study performed at a tertiary referral center. Participants were recruited by newspaper advertisement and randomized to treatment with Danshen (water-extract of the Salvia Miltiorrhiza root or placebo for 4 consecutive weeks. There was a wash out period of 4 weeks. Of the 20 analysed participants, 11 received placebo first. Inclusion criteria were: age 40-70 years, hyperlipidemia and hypertension. At the end of each treatment period, plasma lipids were determined (primary outcome, 24 hours ambulant blood pressure measurement (ABPM was performed, and vasodilator endothelial function was assessed in the forearm.LDL cholesterol levels were 3.82±0.14 mmol/l after Danshen and 3.52±0.16 mmol/l after placebo treatment (mean±SE; p<0.05 for treatment effect corrected for baseline. Danshen treatment had no effect on blood pressure (ABPM 138/84 after Danshen and 136/87 after placebo treatment. These results were further substantiated by the observation that Danshen had neither an effect on endothelial function nor on markers of inflammation, oxidative stress, glucose metabolism, hemostasis and blood viscosity.Four weeks of treatment with Danshen (water-extract slightly increased LDL-cholesterol without affecting a wide variety of other risk markers. These observations do not support the use of Danshen to prevent or treat atherosclerosis.ClinicalTrials.gov NCT01563770.

    Background Green tea intake has been shown to improve endurance capacity in animal studies, but whether it has a similar effect on humans remains unclear. A randomized, double-blinded, parallel-controlled study was conducted to evaluate the short-term effect of STA-2, a pharmaceutical preparation of green tea polyphenols, in patients with effort-induced angina and documented positive exercise tolerance test. Methods A total of 79 patients recruited from three medical centers were randomly assigned to receive 2 STA-2 250 mg capsules, each containing 100 mg green tea polyphenols, three times daily, or placebo for six weeks after two consecutive symptom-limited treadmill exercise tests to ascertain the reproducibility of exercise tolerance. Results There was no difference in total exercise tolerance time from baseline to Week 6 between two groups (p = 0.639). There were also no observed improvements in subgroup analyses stratified by age, gender, and BMI categories. However, a significant reduction in low-density lipoprotein levels was shown in patients in the STA-2 group (-8.99 ± 19.18 mg/dL) versus the placebo group (0.57 ± 19.77 mg/dL), p = 0.037, with greater benefits in patients not taking antihyperlipidemic drugs (STA-2: -9.10 ± 19.96 mg/dL vs. placebo: 4.42 ± 15.08 mg/dL, p = 0.037). Conclusions STA-2 treatment for 6 weeks did not increase exercise time as measured on a treadmill. However, this study also indicated that STA-2 treatment could have potential beneficial effects on LDL-cholesterol concentrations. PMID:27471357

    Full Text Available Leprosy Type 1 (T1R reactions are immune-mediated events leading to nerve damage and preventable disability affecting hands, feet and eyes. Type 1 Reactions are treated with oral corticosteroids. There is little evidence on alternative treatments for patients who do not respond to steroids or experience steroid adverse effects. We report the results of a randomized controlled trial testing the efficacy and adverse effect profile of ciclosporin and prednisolone (CnP in comparison to prednisolone only (P in patients with new T1R in Ethiopia. Ciclosporin is a potent immunosuppressant. Outcomes were measured using a clinical severity score, recurrence rate, adverse events and quality of life.Seventy three patients with new T1R were randomized to receive CnP or P for 20 weeks. Recovery rates in skin signs was similar in both groups (91% vs 88%. Improvements in nerve function both,
