    Carpal tunnel syndrome(CTS) is the most common neuromuscular cause of upper extremity disability. We aimed to investigate the effectiveness of peloid therapy in patients with CTS. This randomized, controlled, single-blind study enrolled 70 patients between the ages of 30 to 65 who had a diagnosis of either mild, mild-to-moderate, or moderate CTS. The patients were randomized into two groups using random number table. In the first group, (Group 1)( n = 35), patients were given splint (every night for 6 weeks) + peloid treatment(five consecutive days a week for 2 weeks) and in the second group, (Group 2)( n = 28), patients received splint treatment(every night for 6 weeks) alone. The patients were assessed by using visual analog scale(VAS) for pain, electroneuromyography(ENMG), the Boston Carpal Tunnel Syndrome Questionnaire(BCTSQ), hand grip strength(HGS), finger grip strength(FGS), and Short Form-12(SF-12). The data were obtained before treatment(W0), immediately after treatment(W2), and one month after treatment(W6). Both in Group 1 and 2, there was a statistically significant improvement in all the evaluation parameters at W2 and W6 when compared to W0( p < 0.05). Comparison of the groups with each other revealed significantly better results for VAS, BCTSQ, mSNCV, SF-12 in Group 1 than in Group 2 at W2( p < 0.05). There was also a statistically significant difference in favor of Group 1 for VAS, BCTSQ, FGS and MCS at W6 when compared to W0 ( p < 0.05). The results of our study demonstrated that in patients with CTS; peloid + splint treatment was more effective than splint treatment alone in pain, functionality and life quality both at after treatment(W2) and one month after treatment (W6). We may suggest peloid as a supplementary therapeutic agent in CTS.

    Non-thyroidal illness syndrome (NTIS) is common among patients with advanced chronic kidney disease (CKD) and is strongly associated with poor prognosis. However, it remains unclear in how to correct this disorder and this study aimed to evaluate the effectiveness of sodium bicarbonate (SB) and N-acetyl-cysteine (NAC) for correcting NTIS status. Patients with CKD stage 3-4 were single-blind, placebo-controlled treated with placebo, SB, or NAC for 18 weeks. The primary end points were the correction of NTIS and the occurrence of end-stage renal disease (ESRD). The secondary point was the change in estimated glomerular filtration rate (eGFR) after the follow-up. The Kaplan-Meier survival analysis showed significant lower correcting ratio of NTIS in control group compared with SB group [Hazard ratio (HR) 0.19, 95 % confidence interval (CI) 0.04-0.89, p = 0.035] and NAC group (HR 0.09, 95 % CI 0.02-0.38, p = 0.001), and increased ESRD risk in control group than in SB group (HR 1.97, 95 % CI 1.02-3.84, p = 0.045) and NAC group (HR 5.50, 95 % CI 2.23-13.57, p < 0.001). The Cox regression analysis demonstrated significantly different effectiveness of placebo, SB and NAC on NTIS correction and ESRD risk, p < 0.05, respectively. Variance analysis displayed a greater reduction in eGFR in controls than in SB (p = 0.044) and NAC group (p < 0.001). SB and NAC are effective in promoting the recovery from NTIS status and delaying the deterioration of renal function in advanced CKD patients.

    Full Text Available Background and Objectives: This study was conducted with the primary objective of evaluating efficacy of Homoeopathy in establishing the menstrual regularity with improvement in either ultrasonological findings or hirsutism/acne. The quality of life was also assessed using polycystic ovary syndrome questionnaire (PCOSQ. Materials and Methods: A single-blind, randomised, placebo-controlled pilot study was conducted from February 2014 to May 2015 at two research centres. The cases fulfilling the eligibility criteria were enrolled (n = 60 and randomised to either the homoeopathic intervention (HI (n = 30 or identical placebo (P (n = 30 with uniform lifestyle modification (LSM for 6 months. Results: The menstrual regularity with improvement in other signs/symptoms was observed in 60% of the cases (n = 18 in HI + LSM group and none (n = 0 in control group (P = 0.001. Statistically significant difference (P = 0.016 was observed in reduction of intermenstrual duration (from 76.1 ± 37.7 to 46.6 ± 38.7 days in HI + LSM in comparison to placebo + LSM group (from 93.0 ± 65.2 to 93.9 ± 96.2 days. In PCOSQ, also, significant improvement was observed in HI group in domains of weight, fertility, emotions and menstrual problems (P < 0.05 with no difference in body hair (P = 0.708. No change was observed in respect of improvement in the ultrasound findings. Pulsatilla was the most frequently indicated medicine (n = 12, 40%. Conclusion: HI along with LSM has shown promising outcome; further comparative study with standard conventional treatment on adequate sample size is desirable.

    Background At least 25 % of women attending genitourinary medicine (GUM) clinics receive treatment for one of the three common causes of abnormal vaginal discharge: bacterial vaginosis, candidiasis and trichomoniasis. Syndromic diagnostic approach was adopted by National AIDS Control Organisation (NACO) India, at the primary health centre level. Syndromic management implies the simultaneous treatment of two or more infections. The aim of this study was to assess efficacy of sandal sufaid, maghze tukhme bakayin and khaste tamar hindi in syndromic management of Sailanur rehm. Methods This study was a randomized, single blind, standard controlled trial. It was conducted to compare efficacy of formulation which contains buradae sandal safaid, safoofe maghze tukhme bakayin, safoofe khaste tamar hindi and safoofe shakkar safaid against combination of azithromycin, fluconazole and secnidazole on diagnosed subjects of Sailanur rehm. Test group received 10 g of test drug B.D for 21 days while control group received single dose of standard drug to both the partners. Vaginal symptom score (VSS) was used for assessing discharge and associated complaints. Visual analogous scale (VAS) was used for assessing low backache and lower abdominal pain. Results There were no significant differences between the two groups concerning baseline characteristics (p>0.05). VSS was significantly decreased with p<0.001 for both control and test group. VAS was significantly decreased with p<0.001 and p=0.07 in test and control group respectively for low backache. For lower abdominal pain p=0.006 for both groups after the completion of treatment. Conclusions The formulation can effectively alleviate the disease with associated symptoms without any side effects. It can be used in syndromic management of vaginal discharge. Future research is on large sample size.

    Traditional rehabilitation improves pain and function in patients with shoulder impingement syndrome. Neurocognitive rehabilitation has shown to be highly effective after surgical reconstruction of the anterior cruciate ligament. However, its effects in patients with shoulder impingement syndrome have not yet been established. The aim of the study was to compare the effects of neurocognitive therapeutic exercise, based on proprioception and neuromuscular control, on pain and function in comparison to traditional therapeutic exercise in patients with shoulder impingement syndrome. Single-blind randomized, non-inferiority clinical trial. Outpatient clinic of Geriatrics and Physiatrics, University Hospital. Forty-eight patients with shoulder impingement syndrome (Neer stage I) and pain lasting for at least three months. Participants were randomly allocated (1:1) to either neurocognitive therapeutic exercise or traditional therapeutic exercise. Both treatments were provided one-hour session, three times a week for five weeks. The primary outcome measure was the short form of the Disability of the Arm, Shoulder and Hand Questionnaire (Quick-DASH questionnaire) for the assessment of physical ability and symptoms of the upper extremity. Constant-Murley shoulder outcome score for the determination of range of motion, pain and strength; American Shoulder and Elbow Surgeons Society standardized shoulder assessment form for the evaluation of physical ability in daily-living tasks; a visual analogue scale for pain assessment at rest and during movements; Likert score for the estimation of participant satisfaction. before treatment, end of treatment, 12 and 24 weeks after the completion of each intervention for all outcome measures, except for the Likert score that was evaluated only at the end of treatment. 24 weeks. At the end of treatment and at follow-up, both treatment groups experienced improvements in all outcomes measures relative to baseline values, except for the

    A single-center, single-blind, parallel-group, randomized clinical trial was performed to test the null hypothesis that adrenocorticotropic hormone is not superior to high-dose prednisolone for treatment of newly diagnosed West syndrome. Newly diagnosed infants with West syndrome were randomized to receive 14 days of oral prednisolone (40-60 mg/day) or a synthetically prepared intramuscular long-acting adrenocorticotropic hormone (40-60 IU/every other day [0.5-0.75 mg]) according to the United Kingdom Infantile Spasm Study protocol. They were blindly evaluated for infantile spasm remission by day 14, electroclinical remission (spasm cessation + resolution of hypsarrhythmia on a 30-minute electroencephalograph) by day 14 and continued spasm freedom for 28 days. Ninety-seven patients were enrolled in the study, with 48 of them receiving prednisolone and 49 receiving ACTH. There was no significant difference in the baseline characteristics or risk factors for the two treatment groups. By day 14, cessation of infantile spasms occurred in 28/48 (58.3%) infants on prednisolone compared with only 18/49 (36.7%) infants given adrenocorticotropic hormone (P = 0.03) and electroclinical remission in 21 on prednisolone compared with nine on adrenocorticotropic hormone (P = 0.007). Sustained spasm control for 28 consecutive days following electroclinical remission occurred in 15 children on prednisolone compared with six on adrenocorticotropic hormone (P = 0.008). The total number of days required for spasm cessation was significantly less in those treated with prednisolone (3.85 days ± 2.4) compared with adrenocorticotropic hormone (8.65 days ± 3.7) (P = 0.001). Among patients who did not achieve remission, there was a non-significant trend toward greater quantitative reduction of spasms with prednisolone than with adrenocorticotropic hormone (P = 0.079). Synthetic adrenocorticotropic hormone of 40-60 IU/every other day did not yield superior rates of electroencephalographic

    Introduction A number of studies have established that children, adolescents and adults with Asperger syndrome (AS) and high functioning autism (HFA) have significant problems with anxiety. Cognitive behavioural therapy (CBT) is an effective treatment for anxiety in a variety of clinical populations. There is a growing interest in exploring the effectiveness of CBT for people with AS who have mental health problems, but currently there are no known clinical trials involving adults with AS or HFA. Studies with children who have AS have reported some success. The current study aims to examine whether modified group CBT for clinically significant anxiety in an AS population is likely to be efficacious. Methods and analysis This study is a randomised, single-blind crossover trial. At least 36 individuals will be recruited and randomised into a treatment arm or a waiting-list control arm. During treatment, individuals will receive 3 sessions of individual CBT, followed by 21 sessions of group CBT. Primary outcome measures focus on anxiety. Secondary outcome measures focus on everyday social and psychiatric functioning, additional measures of anxiety and fear, depression, health-related quality of life and treatment cost. Assessments will be administered at pregroup and postgroup and at follow-up by researchers who are blinded to group allocation. The trial aims to find out whether or not psychological treatments for anxiety can be adapted and used to successfully treat the anxiety experienced by people with AS. Furthermore, we aim to determine whether this intervention represents good value for money. Ethics and dissemination The trial received a favourable ethical opinion from a National Health Service (NHS) Research Ethics Committee. All participants provided written informed consent. Findings will be shared with all trial participants, and the general public, as well as the scientific community. Trial Registration ISRCTN 30265294 (DOI: 10.1186/ISRCTN30265294), UKCRN

    Treatment of restless legs syndrome (RLS) is primarily based on drugs. Since many patients report improvement of symptoms due to cooling their legs, we examined the efficacy of cryotherapy in RLS. 35 patients (28 women, 60.9±12.5years) with idiopathic RLS and symptoms starting not later than 6pm were randomized into three groups: cold air chamber at -60°C (n=12); cold air chamber at -10°C (n=12); local cryotherapy at -17°C (n=11). After a two week baseline, the different therapies were applied three minutes daily at 6pm over two weeks, followed by a four week observation period. The patients completed several questionnaires regarding RLS symptoms, sleep, and quality of life on a weekly basis (IRLS, ESS), VAS and sleep/morning protocol were completed daily, MOSS/RLS-QLI were completed once in each period. Additionally, the PLM index was measured by a mobile device at the end of baseline, intervention, and follow-up. The IRLS score was chosen as primary efficacy parameter. At the end of follow-up, significant improvement of RLS symptoms and quality of life could be observed only in the -60°C group as compared to baseline (IRLS: p=0.009; RLS-QLI: p=0.006; ESS: p=0.020). Local cryotherapy led to improvement in quality of life (VAS4: p=0.028; RLS-QLI: p=0.014) and sleep quality (MOSS: p=0.020; MOSS2: p=0.022) but not in IRLS and ESS. In the -10°C group, the only significant effect was shortening of number of wake phases per night. Serious side-effects were not reported. Whole body cryotherapy at -60°C and, to a less extent, local cryotherapy seem to be a treatment option for RLS in addition to conventional pharmacological treatment. However, the exact mode of cryotherapy needs to be established. Copyright © 2016. Published by Elsevier B.V.

    Full Text Available Purpose Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS exhibits variable lower urinary tract symptoms (LUTS. The aim of this study was to evaluate the incidence of LUTS and the efficacy of an anticholinergic agent in young and middle-aged CP/CPPS patients. Methods Ninety-six men with CP/CPPS were randomly assigned in a single-blind fashion and received either ciprofloxacin (group 1, 49 patients or ciprofloxacin and solifenacin (5 mg/day; group 2, 47 patients for 8 weeks. The National Institutes of Health chronic prostatitis symptom index (NIH-CPSI, the International Prostate Symptom Score (IPSS, and the International Index of Erectile Function-5 (IIEF-5 were used to grade the patients' symptoms and the quality of life impact at the start of the study, and at 4 and 8 weeks from the initiation of the study. Results There was no significant difference between groups 1 and 2 with respect to age, duration of disease, or sub-domains of the IPSS, NIH-CPSI, or IIEF-5 at baseline. Of these patients, 67.4% had LUTS. Statistically significant differences were determined via the NIH-CPSI for total score and the pain and urinary domain scores. Statistically significant differences were determined via the IPSS for total score and the storage domain score. The total score of the IIEF-5 increased, but the change was not significant. There was no statistically significant difference in residual urine. Conclusions Many CP/CPPS patients had LUTS. Solifenacin in CP/CPPS demonstrated improvements in the NIH-CPSI and the IPSS total score and storage score. Storage factors significantly improved via the NIH-CPSI and IPSS assessments in the solifenacin treatment group.

    We earlier completed a single-blind, parallel-group, randomized clinical trial to test the null hypothesis that adrenocorticotropic hormone (ACTH) is not superior to high-dose prednisolone for short-term control of West syndrome. We now present long-term follow-up data for spasm control for individuals who completed this earlier trial. Infants with untreated West syndrome were randomized to receive 14 days of prednisolone (40 to 60 mg/day) or intramuscular long-acting ACTH (40 to 60 IU every other day). They were evaluated at three, six, and 12 months to evaluate long-term spasm control. The total number of infants treated was 97 (48 prednisolone; 49 ACTH). All completed the treatment course. Eighty-five, 82, and 76 children were available for follow-up at three, six, and 12 months. The number lost to follow-up at each interval was not statistically different. Likelihood of spasm freedom at three months was significantly higher for prednisolone (64.6%) than for ACTH (38.8%) (P = 0.01; odds ratio = 2.9; 95% confidence interval = 1.3 to 6.6). At six months (P = 0.19) and twelve months (P = 0.13), the control of spasms was not statistically different, although a trend in favor of prednisolone was documented at both of these time points (58.3% versus 44.9% for ACTH at six months and 56.2% versus 40.8% with ACTH at 12 months). After initial remission by day 14 (n = 46), the likelihood of a relapse within the next 12 months was not statistically different between the two treatment groups (P = 0.1). Control of spasms at three months was significantly better if initially treated with prednisolone. Control of spasms at six and 12 months was not significantly different despite a trend favoring prednisolone. Risk of relapse following initial remission was similar in the two groups.

    Full Text Available Abstract Background Carpal tunnel syndrome is the most common neuropathy in the upper extremity, resulting from the compression of the median nerve at wrist level. Clinical studies are essentials to present evidence on therapeutic resources use at early restoration on peripheral nerve functionality. Low-level laser therapy has been widely investigated in researches related to nerve regeneration. Therefore, it is suggested that the effect of low-level laser therapy associated with other conservative rehabilitation techniques may positively affect symptoms and overall hand function in compressive neuropathies such as carpal tunnel syndrome. The aim of this study is to evaluate the effectiveness of low-level laser therapy in addition to orthoses therapy and home orientations in patients with carpal tunnel syndrome. Methods/Design Patients older than 18 years old will be included, with clinical diagnosis of carpal tunnel syndrome, excluding comorbidies. A physiotherapist will conduct intervention, with a blinding evaluator. Randomization will be applied to allocate the patients in each group: with association or not to low-level laser therapy. All of them will be submitted to orthoses therapy and home orientations. Outcome will be assessed through: pain visual analogic scale, Semmes Weinstein monofilaments™ threshold sensibility test, Pinch Gauge™, Boston Carpal Tunnel Questionnaire and two point discrimination test. Discussion This paper describes the design of a randomized controlled trial, which aim to assess the effectiveness of conservative treatment added to low-level laser therapy for patients with carpal tunnel syndrome.

    Post-polio syndrome (PPS) is a condition that affects polio survivors years after recovery from an initial acute infection by the Poliomyelitis virus. Most often, patients who suffered from polio start to experience gradual new weakening in muscles, a gradual decrease in the size of muscles (muscle atrophy) and fatigue years after the acute illness. L-citrulline is known to change muscular metabolism synthesis by raising nitric oxide (NO) levels and increasing protein synthesis. This investigator-initiated, randomised, placebo-controlled, double-blind, trial aims to demonstrate that L-citrulline positively influences muscle function and increases muscular energy production in patients with PPS. Thirty ambulant PPS patients will be recruited in Switzerland. Patients will be randomly allocated to one of the two arms of the study (placebo:verum 1:1). After a 24-week run-in phase to observe natural disease history and progression, participants will be treated either with L-citrulline or placebo for 24 weeks. The primary endpoint is change in the 6-min Walking Distance Test.

    Full Text Available Background: The most common reproductive endocrine disorder of reproductive age women is a Poly cystic ovary syndrome (PCOS Metabolic syndrome has been more reported in patients with PCOS in comparison to general population. Few investigations have been performed to evaluate the independent effect of exercise on biochemical and clinical symptoms of patients with PCOS. The aim of the study was to find the effect of home base aerobic-strengthening exercises on anthropometric and hormonal variables of patients with PCOS.MaterialsandMethods:In this randomized controlled trial twenty women in the exercise group performed aerobic, strengthening exercises; the other 20 participants in the control group were advised to continue their previous physical activity pattern. Blood pressure, Waist to Hip ratio (WHR, BMI along with hormonal variables(including insulin related factors, sexual hormones and inflammatory factors were assessed at baselineand after the 12 week intervention.Results:16patients in the exercise group and 14 patients in control group finished the study. TheWHR (p<0.001 along with the blood level of insulin (p=0.016, FBS (p=0.044, Prolactine (p=0.022 and hsCRP (p=0.035 and HOMA index (p=0.009 were decreased significantly in the exercise group compared with the control group. No significant differences were found in lipid profile and sexual hormones between groups at the end of the study.Conclusion:We can conclude that 12 weeks combined aerobic-strengthening exercise program in women with poly cystic ovary syndrome can lead to a reduction of waist to hip ratio (WHR and some cardiovascular risk factors (including insulin, FBS, HOMA index and HsCRP along with an increase of prolactine level in these patients.

    Uraemic restless legs syndrome (RLS) affects a significant proportion of patients receiving haemodialysis (HD) therapy. Exercise training has been shown to improve RLS symptoms in uraemic RLS patients; however, the mechanism of exercise-induced changes in RLS severity is still unknown. The aim of the current randomized controlled exercise trial was to investigate whether the reduction of RLS severity, often seen after training, is due to expected systemic exercise adaptations or it is mainly due to the relief that leg movements confer during exercise training on a cycle ergometer. This is the first randomized controlled exercise study in uraemic RLS patients. Twenty-four RLS HD patients were randomly assigned to two groups: the progressive exercise training group (n = 12) and the control exercise with no resistance group (n = 12). The exercise session in both groups included intradialytic cycling for 45 min at 50 rpm. However, only in the progressive exercise training group was resistance applied, at 60-65% of maximum exercise capacity, which was reassessed every 4 weeks to account for the patients' improvement. The severity of RLS symptoms was evaluated using the IRLSSG severity scale, functional capacity by a battery of tests, while sleep quality, depression levels and daily sleepiness status were assessed via validated questionnaires, before and after the intervention period. All patients completed the exercise programme with no adverse effects. RLS symptom severity declined by 58% (P = 0.003) in the progressive exercise training group, while a no statistically significant decline was observed in the control group (17% change, P = 0.124). Exercise training was also effective in terms of improving functional capacity (P = 0.04), sleep quality (P = 0.038) and depression score (P = 0.000) in HD patients, while no significant changes were observed in the control group. After 6 months of the intervention, RLS severity (P = 0.017), depression score (P = 0.002) and

    Full Text Available Objective  To evaluate the efficacy and safety of polysomnography-manual continuous positive airway pressure titration (PSG-CPAP, polysomnography-automatic positive airway pressure titration (PSG-APAP, or automatic positive airway pressure titration (APAP in patients with moderate or severe simple obstructive sleep apnea syndrome (OSAS. Methods  Twenty patients with moderate or severe OSAS sequentially underwent PSG-CPAP, PSG-APAP and APAP titration 3 days apart, and then 3 primary efficacy indicators (titration pressure, remaining respiratory event and state of sleep, and safety indicators (compression injury of face skin, the subjective evaluation on degree of comfort or any complaint during titration were compared. Results  The results of efficacy indicators revealed that all PSG-APAP, APAP and PSG-CPAP were effective. Compared with the optimal pressure of PSG-CPAP titration, PSG-APAP and APAP pressures were 3.05 and 2.55cmH2O higher, respectively, in 90% of occasion (P0.05. There was no statistically significant difference between the optimal pressure of PSG-CPAP and the mean pressures of PSG-APAP and APAP (P>0.05.

    Context • Obstructive sleep apnea/hypopnea syndrome (OSAHS) is among the most prevalent of sleep-related breathing disorders. No long-term follow-up studies have documented the continued success of lifestyle changes in treatment; oral appliances have an approximate 50% success rate; compliance with continuous positive airway pressure is poor, ranging from 50% to 89%; and the success rate of upper-airway surgery is only 66.4%. Therefore, some OSAHS patients seek alternative treatments. Objectives • The study intended to examine the efficacy of traditional Chinese therapeutic massage (tui na) for patients with OSAHS. Design • The research team designed a prospective study. Setting • The study took place at the outpatient clinic of the sleep center at the Kaohsiung Chang Gung Memorial Hospital (Kaohsiung, Taiwan), an academic tertiary medical center. Participants • Participants were 31 patients with moderate to severe OSAHS. Intervention • Each participant received a tui na treatment at multiple acupoints 2 ×/wk for 10 wk for approximately 15 min/session. Outcome Measures • At baseline and 3 mo after treatment, participants completed subjective measures, including (1) quality of life using a 36-item, short-form health survey (SF-36); (2) subjective snoring intensity indicated by bed-partners using a 0-10 visual analog scale (VAS); and (3) excessive daytime sleepiness (EDS) status, using a Chinese version of the Epworth Sleepiness Scale (CESS). The research team completed objective measures, including (1) polysomnography, (2) body mass index, and (3) neck circumference. Results • Twenty patients completed the full course of treatment. The apnea/hypopnea index per hour decreased from 43.8 ± 26.9 to 37.8 ± 31.7 after the treatments, with P = .049 (paired t test). The arousal index and rapid eye movement stage of sleep improved significantly. Statistically significant improvements were observed for the SF-36 on the score for the physical component

    The role of therapy on improvement of hypsarrhythmia has not been systematically assessed. This study was performed to assess the efficacy of oral prednisolone and intramuscular adrenocorticotrophin hormone in improving hypsarrhythmia in West syndrome. Children (2 months-2 years), with previously untreated West syndrome, were randomized to receive 40-60 IU every other day of intramuscular adrenocorticotrophin hormone or 40-60 mg/day of oral prednisolone for 14 days. Children with tuberous sclerosis were excluded. Improvement of hypsarrhythmia was assessed blindly using a hypsarrhythmia severity scale before and after completion of therapy. Adverse effects were assessed on day 14 using symptom diary. (Clinical trial registry identifier: SLCTR/2010/010.) From 92 newly diagnosed West syndrome infants, 48 were randomized to receive prednisolone and 44 to receive adrenocorticotrophin hormone. Eighty infants completed the posttreatment evaluation according to specifications.

    Peer review may be "single-blind," in which reviewers are aware of the names and affiliations of paper authors, or "double-blind," in which this information is hidden. Noting that computer science research often appears first or exclusively in peer-reviewed conferences rather than journals, we study these two reviewing models in the context of the 10th Association for Computing Machinery International Conference on Web Search and Data Mining, a highly selective venue (15.6% acceptance rate) in which expert committee members review full-length submissions for acceptance. We present a controlled experiment in which four committee members review each paper. Two of these four reviewers are drawn from a pool of committee members with access to author information; the other two are drawn from a disjoint pool without such access. This information asymmetry persists through the process of bidding for papers, reviewing papers, and entering scores. Reviewers in the single-blind condition typically bid for 22% fewer papers and preferentially bid for papers from top universities and companies. Once papers are allocated to reviewers, single-blind reviewers are significantly more likely than their double-blind counterparts to recommend for acceptance papers from famous authors, top universities, and top companies. The estimated odds multipliers are tangible, at 1.63, 1.58, and 2.10, respectively. Copyright © 2017 the Author(s). Published by PNAS.

    Tiagabine, a specific gamma-aminobutyric acid-uptake inhibitor, has been shown to be reasonably well tolerated and efficacious as adjunctive treatment for partial seizures in adults and is now being investigated in children. This 4-month, single-blind study evaluated the tolerability, safety and preliminary efficacy of ascending doses (0.25-1.5 mg/kg/day) of tiagabine add-on therapy in 52 children over the age of 2 years with different syndromes of refractory epilepsy. Adverse events, mostly mild to moderate, were reported by 39% of children during the single-blind placebo period and by 83% of children during tiagabine treatment. The events predominantly affected the nervous system with asthenia (19%), nervousness (19%), dizziness (17%) and somnolence (17%) being the most common. Only three children (6%) withdrew because of adverse events. Tiagabine appeared to reduce seizures more in localisation-related epilepsy syndromes than in generalised epilepsy syndromes. Twenty-three patients with localisation-related epilepsy syndromes were included and 17 of these patients entered the fourth dosing period. The 17 patients had a median reduction of seizure rate in the fourth month of treatment of 33% compared with baseline. In comparison, 13 of 22 children with seven different generalised epilepsy syndromes entered the fourth dosing period with a median change of seizure rate of 0%. Two patients experienced single episodes of status epilepticus during treatment; both cases resolved. Tiagabine showed efficacy mainly in localisation-related syndromes and was well tolerated by most children in a group of very refractory patients and warrants further study in children with epilepsy.

    Full Text Available Fat embolism syndrome is a well-recognised sequela of long bone trauma as well as intramedullary orthopaedic procedures. However, it has rarely been described following manipulation, reduction of fracture, and application of external fixator. Furthermore, bilateral ocular blindness is seldom the first manifestation; instead respiratory and other cerebral symptoms being most common. We describe a case with this rare presentation in a patient who underwent a trial of closed reduction, then open reduction of a femur fracture, followed by external fixation performed at day 47 post-initial trauma.

    Although orbital compartment syndrome is a rare condition, it is still the most common cause of blindness following simple or complicated facial fractures. Its pathomechanism is similar to the compartment syndrome in the limb. Little extra fluid (blood, oedema, brain, foreign body) in a non-space yielding space results with increasingly higher pressures within a short period of time. Unless urgent surgical intervention is performed the blocked circulation of the central retinal artery will result irreversible ophthalmic nerve damage and blindness. Aim, material and method: A retrospective analysis of ten years, 2007-2017, in our hospital among those patients referred to us with facial-head trauma combined with blindness. 571 patients had fractures involving the orbit. 23 patients become blind from different reasons. The most common cause was orbital compartment syndrome in 17 patients; all had retrobulbar haematomas as well. 6 patients with retrobulbar haematoma did not develop compartment syndrome. Compartment syndrome was found among patient with extensive and minimal fractures such as with large and minimal haematomas. Early lateral canthotomy and decompression saved 7 patients from blindness. We can not predict and do not know why some patients develop orbital compartment syndrome. Compartment syndrome seems independent from fracture mechanism, comminution, dislocation, amount of orbital bleeding. All patients are in potential risk with midface fractures. We have a high suspicion that orbital compartment syndrome has been somehow missed out in the recommended textbooks of our medical universities and in the postgraduate trainings. Thus compartment syndrome is not recognized. Teaching, training and early surgical decompression is the only solution to save the blind eye. Orv Hetil. 2017; 158(36): 1410-1420.

    We compared the efficacy and safety of trigonal injections of onabotulinumtoxinA and saline in patients with bladder pain syndrome/interstitial cystitis. This phase II study enrolled women who had had bladder pain syndrome/interstitial cystitis for more than 6 months and pain for 4 months or longer on a visual analogue scale of 0 to 10, which were refractory to common treatment. OnabotulinumtoxinA 100 U in 10 or saline as placebo in 9 was administered as 10 trigonal injections of 1 ml. The primary study end point was the change from baseline pain intensity reported at week 12. Additional end points included O'Leary-Sant scores, micturition frequency, quality of life at week 4, 8 and 12, and the treatment benefit scale at week 12. Safety assessments included urinary tract infection, post-void residual urine and the initiation of clean intermittent catheterization. At week 12 onabotulinumtoxinA had significantly reduced pain compared with saline (mean ± SD -3.8 ± 2.5 vs -1.6 ± 2.1, p interstitial cystitis refractory to common therapy.

    The management of chronic prostatitis/ chronic pelvic pain syndrome type III (CP/CPPS) has been always considered complex due to several biopsychological factors underling the disease. In this clinical study, we aimed to evaluate the efficacy of the treatment with Curcumin and Calendula extract in patients with CP/CPPS III. From June 2015 to January 2016 we enrolled 60 consecutive patients affected by CP/CPPS III in our institution. Patients between 20 and 50 year of age with symptoms of pelvic pain for 3 months or more before study, a total National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) score ≥ 15 point and diagnosed with NIH category III. Patients were then allocated to receive placebo (Group A) or treatment (Group B). Treatment consisted of rectal suppositories of Curcumin extract 350 mg (95%) and Calendula extract 80 mg (1 suppository/die for 1 month). Patients of Group B received 1 suppository/die for 1 month of placebo. The primary endpoint of the study was the reduction of NIH-CPSI. The secondary outcomes were the change of peak flow, IIEF-5, VAS score and of premature ejaculation diagnostic tool (PEDT). A total of 48 patients concluded the study protocol. The median age of the all cohort was 32.0 years, the median NIH-CPSI was 20.5, the median IIEF-5 was 18.5, the median PEDT was 11.0, the median VAS score was 7.5 and the median peak flow was 14.0. After 3 months of therapy in group A we observed a significant improvement of NIH-CPSI (-5.5; p < 0.01), IIEF-5 (+ 3.5; p < 0.01), PEDT (-6.5; p < 0.01), peak flow (+2.8; p < 0.01) and VAS (-6.5; p < 0.01) with significant differences over placebo group (all p-value significant). In this phase II clinical trial we showed the clinical efficacy of the treatment with Curcumin and Calendula in patients with CP/CPPS III. The benefits of this treatment could be related to the reduction of inflammatory cytokines and of inflammatory cells. These results should be confirmed in further studies

    2016-01-01

    Restless legs syndrome is an underdiagnosed sensori-motor disorder and psychotropic drugs are one of the main secondary causes of the illness. The most common psychotropic agents that cause restless legs syndrome are antidepressants; however, antipsychotics have also been reported to induce restless legs syndrome. The prevalence, vulnerability factors and the underlying mechanism of antipsychotic-induced restless legs syndrome are unclear. A possible explanation is that dopaminergic blockade is the main precipitator of the syndrome. Quetiapine-induced restless legs syndrome is another point of interest because of its low binding to D2 receptors. We herein report the case of a restless legs syndrome that emerged after a single low dose quetiapine administration.

Fifty patients (mean age: 74.5 years; 32 men) with severe refractory tremor (36 essential, 14 parkinsonian) were treated with unilateral GKT. Targeting of the ventral intermediate nucleus (Vim) was achieved with Leksell Gamma Knife with a single shot through a 4-mm collimator helmet. The prescription dose was 130 Gy. Neurologic and neuropsychological assessments including a single-blinded video assessment of the tremor severity performed by a movement disorders neurologist from another center were performed before and 12 months after treatment. MRI follow-up occurred at 3, 6, and 12 months. The upper limb tremor score improved by 54.2% on the blinded assessment (p < 0.0001). All tremor components (rest, postural, and intention) were improved. Activities of daily living were improved by 72.2%. Cognitive functions remained unchanged. Following GKT, the median delay of improvement was 5.3 months (range 1-12 months). The only side effect was a transient hemiparesis associated with excessive edema around the thalamotomy in one patient. This blinded prospective assessment demonstrates that unilateral GKT is a safe and efficient procedure for severe medically refractory tremor. Side effects were rare and transient in this study. This study provides Class IV evidence that for patients with severe refractory tremor, GKT is well tolerated and effective in reducing tremor impairment. © 2015 American Academy of Neurology.

    This study investigated the effects of Korean red ginseng (KRG) supplementation on metabolic parameters, inflammatory markers, and arterial stiffness in subjects with metabolic syndrome. We performed a randomized, double-blind, placebo-controlled, single-center study in 60 subjects who were not taking drugs that could affect metabolic and vascular functions. Subjects were randomized into either a KRG (4.5 g/d) group or a placebo group for a 12-week study. We collected anthropometric measurements, blood for laboratory testing, and brachial-ankle pulse wave velocity (baPWV) at the initial (week 0) and final (week 12) visits. A total of 48 subjects successfully completed the study protocol. Oral administration of KRG did not significantly affect blood pressure, oxidative or inflammatory markers, or baPWV. We found no evidence that KRG had an effect on blood pressure, lipid profile, oxidized low density lipoprotein, fasting blood glucose, or arterial stiffness in subjects with metabolic syndrome. These findings warrant subsequent longer-term prospective clinical investigations with a larger population. ClinicalTrials.gov Identifier: NCT00976274.

  6. Label-Free, Single Molecule Resonant Cavity Detection: A Double-Blind Experimental Study

    Full Text Available Optical resonant cavity sensors are gaining increasing interest as a potential diagnostic method for a range of applications, including medical prognostics and environmental monitoring. However, the majority of detection demonstrations to date have involved identifying a “known” analyte, and the more rigorous double-blind experiment, in which the experimenter must identify unknown solutions, has yet to be performed. This scenario is more representative of a real-world situation. Therefore, before these devices can truly transition, it is necessary to demonstrate this level of robustness. By combining a recently developed surface chemistry with integrated silica optical sensors, we have performed a double-blind experiment to identify four unknown solutions. The four unknown solutions represented a subset or complete set of four known solutions; as such, there were 256 possible combinations. Based on the single molecule detection signal, we correctly identified all solutions. In addition, as part of this work, we developed noise reduction algorithms.

    In two experiments, we evaluated whether a perceiver's prior expectations could alone obliterate his or her awareness of a salient visual stimulus. To establish expectancy, observers first made a demanding visual discrimination on each of three baseline trials. Then, on a fourth, critical trial, a single, salient and highly visible object appeared in full view at the center of the visual field and in the absence of any competing visual input. Surprisingly, fully half of the participants were unaware of the solitary object in front of their eyes. Dramatically, observers were blind even when the only stimulus on display was the face of U.S. President Barack Obama. We term this novel, counterintuitive phenomenon, Barack Obama Blindness (BOB). Employing a method that rules out putative memory effects by probing awareness immediately after presentation of the critical stimulus, we demonstrate that the BOB effect is a true failure of conscious vision.

    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 sleep quality. The use of novel therapeutic approaches influencing the gut microbiota-muscle-brain axis could be considered for treatment of the frailty syndrome.

    Bardet-Biedl syndrome (BBS) is a genetically heterogeneous disorder affecting multiple organ systems and resulting in blindness, obesity, cognitive impairment, and congenital defects. Interest in the etiology of this disorder stems, in part, from the fact that patients with BBS develop common clinical problems, including obesity, diabetes and hypertension. Twelve genes independently causing BBS have been identified. The heterogeneity is explained by the existence of two BBS complexes, the BBSome consisting of seven known BBS proteins, and the BBS chaperone complex consisting of three known BBS proteins. The formation of the BBSome requires the function of the BBS chaperone complex. Both mouse and zebrafish data support a role for BBS genes in cilia function, and in intracellular and intraflagellar trafficking. From the work described here, a common primary function of BBS proteins has emerged, specifically the mediation and regulation of microtubule-based intracellular transport.

    2014-09-01

    To study the clinical manifestations and the diagnostic and differential diagnostic characteristics of acute idiopathic blind spot enlargement syndrome (AIBSES). Six patients diagnosed with AIBSES underwent complete eye examinations including fundus photography, fundus fluorescein angiography(FFA), indocyanine green angiography (ICGA), optical coherence tomography (OCT), electroretinogram (ERG), and visual field examinations. All patients had enlarged blind spots of variable sizes and densities. Three eyes had mild swelling of the optic disc and one eye had peripapillary scarring that corresponded to the permanent field defect. Two patients who underwent FFA had fluorescein leakage of blood vessels around the optic disc and ICGA highlighted diffuse, small hypofluorescent spots scattering throughout the posterior pole. OCT showed that the inner and outer segment (IS/OS) line were absent in five patients and the middle cone outer segment tip line was absent in the nasal macular area in one eye. AIBSES is a rare outer retinopathy. Visual field examination and OCT are the most important means of detection. ICGA and FAF can determine the range of lesions earlier, and the progress of the disease should be taken into account when making a diagnosis.

    Full Text Available Objective. Keratosis pilaris (KP is a common condition which can frequently be cosmetically disturbing. Topical treatments can be used with limited efficacy. The objective of this study is to evaluate the effectiveness and safety of fractional carbon dioxide (CO2 laser for the treatment of KP. Patients and Methods. A prospective, randomized, single-blinded, intraindividual comparative study was conducted on adult patients with KP. A single session of fractional CO2 laser was performed to one side of arm whereas the contralateral side served as control. Patients were scheduled for follow-up at 4 and 12 weeks after treatment. Clinical improvement was graded subjectively by blinded dermatologists. Patients rated treatment satisfaction at the end of the study. Results. Twenty patients completed the study. All patients stated that the laser treatment improved KP lesions. At 12-week follow-up, 30% of lesions on the laser-treated side had moderate to good improvement according to physicians’ global assessment (p=0.02. Keratotic papules and hyperpigmentation appeared to respond better than the erythematous component. Four patients with Fitzpatrick skin type V developed transient pigmentary alteration. Conclusions. Fractional CO2 laser treatment may be offered to patients with KP. Dark-skinned patients should be treated with special caution.

    Cortical blindness and Balint's syndrome are two pathologies not well-known. It seems therefore interesting to report a typical patient case, suffering from Benson's posterior cortical atrophy, who presented successively both syndromes. The Balint's syndrome, which results from a bilateral parieto-occipital junction brain injury, and combines clinically a specified triad defects: a spatial disorder of attention, a psychic paralysis of gaze and an optic ataxia. The cortical blindness, which is caused by bilateral damage of the occipital lobes (Broadman area 17). Electrophysiologically, the abolition of short-latency components of visual evoked potentials and the presence of long-latency potentials are recorded. Visual strategy and visual evoked potentials are thus the only objective examinations allowing to diagnose and follow up these patient's evolution. In any case, an adequate visual rehabilitation has to be carried out in order to help the patient recovering his autonomy.

    Mobile phone text message technology has the potential to improve outcomes for patients with depression and co-morbid Alcohol Use Disorder (AUD). To perform a randomised rater-blinded trial to explore the effects of supportive text messages on mood and abstinence outcomes for patients with depression and co-morbid AUD. Participants (n=54) with a DSM IV diagnosis of unipolar depression and AUD who completed an in-patient dual diagnosis treatment programme were randomised to receive twice daily supportive text messages (n=26) or a fortnightly thank you text message (n=28) for three months. Primary outcome measures were Beck's Depression Inventory (BDI-II) scores and Cumulative Abstinence Duration (CAD) in days at three months. NCT0137868. There was a statistically significant difference in three month BDI-II scores between the intervention and control groups; 8.5 (SD=8.0) vs. 16.7 (SD=10.3) respectively after adjusting for the baseline scores, F (1, 49)=9.54, p=0.003, η(p)(2)=0.17. The mean difference in change BDI-II scores was -7.9 (95% CI -13.06 to -2.76, Cohen'sd=0.85). There was a trend for a greater CAD in the text message group than the control group: 88.3 (SD=6.2) vs. 79.3 (SD=24.1), t=1.78, df=48, p=0.08. Limitations of the study include the small sample size, the potential for loss of rater blinding and the lack of long term follow-up to determine the longer term effects of the intervention. Supportive text messages have the potential to improve outcomes for patients with comorbid depression and alcohol dependency syndrome. Copyright © 2012 Elsevier B.V. All rights reserved.

    Obesity is a significant health problem in westernized societies, particularly in the United States where it has reached epidemic proportions in both adults and children. The prevalence of childhood obesity has doubled in the past 30 years. The causation is complex with multiple sources, including an obesity promoting environment with plentiful highly dense food sources and overall decreased physical activity noted for much of the general population, but genetic factors clearly play a role. Advances in genetic technology using candidate gene approaches, genome-wide association studies, structural and expression microarrays, and next generation sequencing have led to the discovery of hundreds of genes recognized as contributing to obesity. Polygenic and monogenic causes of obesity are now recognized including dozens of examples of syndromic obesity with Prader-Willi syndrome, as a classical example and recognized as the most common known cause of life-threatening obesity. Genetic factors playing a role in the causation of obesity will be discussed along with the growing evidence of single genes and the continuum between monogenic and polygenic obesity. The clinical and genetic aspects of four classical but rare obesity-related syndromes (ie, Prader-Willi, Alström, fragile X, and Albright hereditary osteodystrophy) will be described and illustrated in this review of single gene and syndromic causes of obesity.

    Aim: To investigate the possibility of whether a single 300 mg dose of ranitidine given orally 2-3 h before magnetic resonance cholangiopancreatography (MRCP) could reduce the signal from the stomach and duodenum, and thus increase the conspicuousness of the biliary tree. Materials and methods: Thirty-five volunteers (22 female, 13 male), (age range 21-50) were underwent MRCP in a double-blind, placebo-controlled, randomized, crossover trial on a Philips Intera 1.5 T machine using a phased array surface coil. Imaging was carried out in the coronal oblique plane. Six 40 mm sections were acquired at varying angles to delineate the biliary tree and pancreatic duct. The 70 examinations were blindly scored by three consultants experienced in cholangiography. Results: After ranitidine administration there was a significant decrease in signal from the stomach (mean = 17.7, p = 0.0005, CI 10, 25.3) and duodenum (mean = 18.4, p = 0.0005, 95%CI 9.6, 27.1) with a significant increase in conspicuousness of the distal common duct (mean = 7.7, p = 0.033, 95%CI 0.7, 14.7) and proximal common duct (mean = 8.7, p = 0.010 CI 2.2, 15.2). There were no adverse effects. Conclusion: Oral ranitidine is a cheap and effective agent to decrease signal from the upper gastrointestinal tract and to improve visibility of the biliary tree.

    2017-01-01

    Full Text Available Background: Histopathologists encounter strange structures in tissue sections that appear unrelated to tissues, and these artifacts may be misinterpreted and misdiagnosed as pathological lesions. These substances may either be present within the tissues or can get implanted into tissue during biopsy procedure or laboratory handling or processing. Aims: The aim of this study is to observe the microscopic appearance of different abnormal structures like commonly implanted food particles or easily incorporated substances during tissue processing with their probable histological misdiagnosis. Materials and Methods: Certain food particles, suture materials, wood pieces, insects, and filter paper were intentionally introduced in the tissue specimens of uterus and lung. Following routine processing and hematoxylin and eosin staining, the slides were subjected to single-blind study and viewed under light and polarizing microscope. Results: The vivid appearances of these structures lead to histological misdiagnosis. Conclusion: Knowledge and familiarity of these commonly encountered extraneous substances will help to prevent misinterpretation.

    OBJECTIVES: To compare two activated charcoal preparations (Carbomix and Actidose-Aqua) in terms of amount ingested and incidence of vomiting after ingestion. METHODS: Single blinded prospective randomised controlled trial. RESULTS: The mean amount of charcoal ingested was Carbomix 26.5 g, Actidose-Aqua 19.5 g. The mean difference was 7 g (95% confidence interval (CI) 1.5 to 12.4 g). The incidence of vomiting was for the Carbomix 6% and the Actidose-Aqua 8%. The mean difference in vomiting was 2% (95% CI -0.8 to 4.8) CONCLUSIONS: Carbomix administration results in an increased amount of activated charcoal ingested after oral administration. Rates of vomiting after activated charcoal administration were low when compared with previously reported rates. PMID:9918281

    A novel single-channel blind source separation (SCBSS) algorithm is presented. The proposed algorithm yields at least three benefits of the SCBSS solution: 1) resemblance of a stereo signal concept given by one microphone; 2) independent of initialization and a priori knowledge of the sources; and 3) it does not require iterative optimization. The separation process consists of two steps: 1) estimation of source characteristics, where the source signals are modeled by the autoregressive process and 2) construction of masks using only the single-channel mixture. A new pseudo-stereo mixture is formulated by weighting and time-shifting the original single-channel mixture. This creates an artificial mixing system whose parameters will be estimated through our proposed weighted complex 2-D histogram. In this paper, we derive the separability of the proposed mixture model. Conditions required for unique mask construction based on maximum likelihood are also identified. Finally, experimental testing on both synthetic and real-audio sources is conducted to verify that the proposed algorithm yields superior performance and is computationally very fast compared with existing methods.

    Nutritional modulation remains central to the management of metabolic syndrome. Intervention with cinnamon in individuals with metabolic syndrome remains sparsely researched. We investigated the effect of oral cinnamon consumption on body composition and metabolic parameters of Asian Indians with metabolic syndrome. In this 16-week double blind randomized control trial, 116 individuals with metabolic syndrome were randomized to two dietary intervention groups, cinnamon [6 capsules (3 g) daily] or wheat flour [6 capsules (2.5 g) daily]. Body composition, blood pressure and metabolic parameters were assessed. Significantly greater decrease [difference between means, (95% CI)] in fasting blood glucose (mmol/L) [0.3 (0.2, 0.5) p = 0.001], glycosylated haemoglobin (mmol/mol) [2.6 (0.4, 4.9) p = 0.023], waist circumference (cm) [4.8 (1.9, 7.7) p = 0.002] and body mass index (kg/m2 ) [1.3 (0.9, 1.5) p = 0.001] was observed in the cinnamon group compared to placebo group. Other parameters which showed significantly greater improvement were: waist-hip ratio, blood pressure, serum total cholesterol, low-density lipoprotein cholesterol, serum triglycerides, and high-density lipoprotein cholesterol. Prevalence of defined metabolic syndrome was significantly reduced in the intervention group (34.5%) vs. the placebo group (5.2%). A single supplement intervention with 3 g cinnamon for 16 weeks resulted in significant improvements in all components of metabolic syndrome in a sample of Asian Indians in north India. The clinical trial was retrospectively registered (after the recruitment of the participants) in ClinicalTrial.gov under the identification number: NCT02455778 on 25th May 2015.

    The aim of this randomized controlled single-blind study is to explore whether addition of mud-pack and hot pool treatments to patient education make a significant difference in short and mild term outcomes of the patients with fibromyalgia. Seventy women with fibromyalgia syndrome were randomly assigned to either balneotherapy with mud-pack and hot pool treatments (35) or control (35) groups. After randomization, five patients from balneotherapy group and five patients from control group were dropped out from the study with different excuses. All patients had 6-h patient education programme about fibromyalgia syndrome and were given a home exercise programme. The patients in balneotherapy group had heated pool treatment at 38 °C for 20 min a day, and mud-pack treatment afterwards on back region at 45 °C. Balneotherapy was applied on weekdays for 2 weeks. All patients continued to take their medical treatment. An investigator who was blinded to the intervention assessed all the patients before and after the treatment, at the first and the third months of follow-up. Outcome measures were FIQ, BDI and both patient's and physician's global assessments. Balneotherapy group was significantly better than control group at after the treatment and at the end of the first month follow-up assessments in terms of patient's and physician's global assessment, total FIQ score, and pain intensity, fatigue, non-refreshed awaking, stiffness, anxiety and depression subscales of FIQ. No significant difference was found between the groups in terms of BDI scores. It is concluded that patient education combined with 2 weeks balneotherapy application has more beneficial effects in patients with fibromyalgia syndrome as compared to patient education alone.

    Full Text Available This report presents the case of a 60-year-old female who demonstrated sick sinus syndrome after a single administration of Garenoxacin (GRNX. She was administered GRNX for an upper respiratory infection and 10 minutes thereafter, she suddenly felt palpitation and numbness of both arms. She was transferred to the hospital 2 hours after taking GRNX. An electrocardiogram showed bradycardia with junctional escape beats and the longest sinus arrest was 4 seconds. She was treated with a temporary pacemaker and 21 hours after the administration of GRNX her sinus node function was observed to have completely improved. GRNX-induced sick sinus syndrome was suspected because her clinical course was compatible with the concentration of GRNX and her other cardiological assessments, including an electrophysiologic study (EPS which were conducted on the 9th day of the admission, were normal. GRNX has less effect on the QT interval than other quinolone agents. However, physicians should be aware of the risk of sick sinus syndrome because GRNX is frequently prescribed in outpatient clinics.

    Diabetes is one of the biggest problems in healthcare systems and kills many people every year. Diabetes management is impossible when only utilizing medication. So, patients must be educated to manage their diabetes. This study aims to assess the effect of education by telephone and short message service on empowering patients with type 2 diabetes (primary outcome). A single-blind randomized controlled trial was conducted in the Urmia diabetes association in Iran. Sixty six participants with definitive diagnosis of type 2 diabetes entered into the study. Patients with secondary health problems were excluded. Patients were selected by simple random sampling then allocated into intervention (n=33) and control (n=33) groups. The intervention group received an educational text message daily and instructive phone calls three days a week for three months along with usual care. The Diabetes Empowerment Scale (DES) with confirmed validity and reliability was used for collecting data. Data was analyzed using SPSS V6.1. Independent t-test, paired t-test and chi-square were used to analyze the data. The empowerment of the intervention group compared with the control group significantly improved after three months of distance education (pdistance education has a significant effect on empowering patients with type 2 diabetes. Therefore, using distance education along with other diabetes management intervention is highly effective and should be part of the care in diabetes treatment. Copyright © 2016 Diabetes India.

    To determine the best approach for live donor nephrectomy to minimise discomfort to the donor and to provide good graft function. Single blind, randomised controlled trial. Two university medical centres, the Netherlands. 100 living kidney donors. Participants were randomly assigned to either laparoscopic donor nephrectomy or to mini incision muscle splitting open donor nephrectomy. The primary outcome was physical fatigue using the multidimensional fatigue inventory 20 (MFI-20). Secondary outcomes were physical function using the SF-36, hospital stay after surgery, pain, operating times, recipient graft function, and graft survival. Conversions did not occur. Compared with mini incision open donor nephrectomy, laparoscopic donor nephrectomy resulted in longer skin to skin time (median 221 v 164 minutes, P fatigue was less (difference - 1.3, 95% confidence interval - 2.4 to - 0.1) and physical function was better (difference 6.2, 2.0 to 10.3) after laparoscopic nephrectomy. Function of the graft and graft survival rate of the recipient at one year censored for death did not differ (100% after laparoscopic nephrectomy and 98% after open nephrectomy). Laparoscopic donor nephrectomy results in a better quality of life compared with mini incision open donor nephrectomy but equal safety and graft function.

  10. A Blind Antenna Selection Scheme for Single-Cell Uplink Massive MIMO

    KAUST Repository

    Elkhalil, Khalil

    2017-02-09

    This paper considers the uplink of a single-cell large-scale multiple-input multiple output (MIMO) system in which m mono-antenna users communicate with a base station (BS) outfitted by n antennas. We assume that the number of antennas at the BS and that of users take large values, as envisioned by large-scale MIMO systems. This allows for high spectral efficiency gains but obviously comes at the cost of higher complexity, a fact that becomes all the more critical as the number of antennas grows large. To solve this issue is to choose a subset of the available n antennas. The subset must be carefully chosen to achieve the best performance. However, finding the optimal subset of antennas is usually a difficult task, requiring one to solve a high dimensional combinatorial optimization problem. In this paper, we approach this problem in two ways. The first one consists in solving a convex relaxation of the problem using standard convex optimization tools. The second technique solves the problem using a greedy approach. The main advantages of the greedy approach lies in its wider scope, in that, unlike the first approach, it can be applied irrespective of the considered performance criterion. As an outcome of this feature, we show that the greedy approach can be applied even when only the channel statistics are available at the BS, which provides blind way to perform antenna selection.

    To investigate the effect of cryotherapy after elbow arthrolysis on elbow pain, blood loss, analgesic consumption, range of motion, and long-term elbow function. Prospective, single-blinded, randomized controlled study. University hospital. Patients (N=59; 27 women, 32 men) who received elbow arthrolysis. Patients were randomly assigned into a cryotherapy group (n=31, cryotherapy plus standard care) or a control group (n=28, standard care). Elbow pain at rest and in motion were measured using a visual analog scale (VAS) on postoperative day (POD) 1 to POD 7 and at 2 weeks and 3 months after surgery. Blood loss and analgesic consumption were recorded postoperatively. Elbow range of motion (ROM) was measured before surgery and on POD 1, POD 7, and 3 months after surgery. The Mayo Elbow Performance Score (MEPS) was evaluated preoperatively and 3 months postoperatively. VAS scores were significantly lower in the cryotherapy group during the first 7 PODs, both at rest and in motion (Pcryotherapy group than the control group for pain relief (P.05). Cryotherapy is effective in relieving pain and reducing analgesic consumption for patients received elbow arthrolysis. The application of cryotherapy will not affect blood loss, ROM, or elbow function. Copyright © 2015 American Congress of Rehabilitation Medicine. Published by Elsevier Inc. All rights reserved.

    The purpose of this single blind study was to investigate effects of Buccotherm® spray on subjective symptoms of xerostomia patients. Twenty patients with dry mouth complaint were instructed to use placebo six times a day for 2 weeks. After a wash period, mineral water spray was provided. Patients were asked to reply questions regarding dry mouth using visual analog scale (VAS). Baseline and subsequent subjective findings on 1 hour after the application of the materials at the end of 1st, 7th, and 14th days were recorded. At the end of 14-day treatment, no statistically significant differences were observed between the efficacy of placebo and commercial mineral water dental spray (p > 0.05). The VAS scores revealed that difficulty in mastication (p = 0.006), difficulty in swallowing (p = 0.00), need to sip liquids while eating (p = 0.000), difficulty in speech (p = 0.003), and waking up at night to sip water (p = 0.005) were statistically lower for placebo than commercial mineral water spray. The commercial mineral water dental spray was not more efficient than placebo in the management of dry mouth-related symptoms. This study emphasizes the fundamental role of saliva in oral health and evaluates the clinical utility of a commercial dental spray. © 2014 Special Care Dentistry Association and Wiley Periodicals, Inc.

    Many patients with painful chronic pancreatitis (CP) have insufficient effect of treatment, and the prevalence of adverse effects is high. Consequently, alternatives to conventional management are needed. We aimed to study the effect of acupuncture in painful CP. This was a prospective, single-blinded, randomized crossover trial. Fifteen patients with CP were assigned to a session of acupuncture followed by sham stimulation or vice versa. Patients rated clinical pain scores daily on a 0 to 10 visual analogue scale (VAS) and completed the Patient Global Impression of Change. For mechanistic linkage, resting state electroencephalograms were recorded and quantified by spectral power analysis to explore effects on central pain processing. Acupuncture, compared with sham stimulation, caused more pain relief (2.0 ± 1.5 VAS vs 0.7 ± 0.8 VAS; P = 0.009). The effect, however, was short, and after 1-week follow-up, there was no difference in clinical pain scores between groups (P = 1.0) or the rating of Patient Global Impression of Change (P = 0.8). Electroencephalogram spectral power distributions between sham and acupuncture were comparable between groups (all P > 0.6). The study presents proof-of-concept for the analgesic effect of acupuncture in pancreatic pain. Although the effect was short lasting, the framework may be used to conceptualize future trials of acupuncture in visceral pain.

    The aim of this study was to assess the effect of peloid on pain, functionality, daily life activities, and quality of life of lateral epicondylitis (LE) patients. In this randomized, controlled, single-blind study, 75 patients who were diagnosed with chronic LE were enrolled to the study. Patients were randomized into two groups using the random number table. The patients in the first group (group 1) ( n = 33), were given lateral epicondylitis band (LEB) (during the day for 6 weeks) + peloid therapy (five consecutive days a week for 2 weeks), and the second group (group 2) ( n = 32), received LEB treatment alone. The patients were assessed by using Patient Rated Tennis Elbow Evaluation (PRTEE) and Nottingham Health Profile (NHP). The data were obtained before treatment (W0), immediately after treatment (W2), and 1 month after treatment (W6). In analysis of the collected data, the Wilcoxon signed rank test for intra-group comparisons and Mann-Whitney U test for comparisons between groups were used. Both in groups 1 and 2, there was a statistically significant improvement in all the evaluation parameters at W2 and W6 when compared to W0 ( p 0.05), a statistically significant difference was found in favor of group 1 for all the evaluation parameters at W6 ( p < 0.05). Our results have shown that peloid treatment could be effective in providing improvement in pain relief, function, daily life activities, and quality of life in LE patients.

    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.

    To evaluate the efficacy of paraffin bath therapy on pain, function, and muscle strength in patients with hand osteoarthritis. Prospective single-blinded randomized controlled trial. Department of physical medicine and rehabilitation in a university hospital. Patients with bilateral hand osteoarthritis (N=56). Patients were randomized into 2 groups with a random number table by using block randomization with 4 patients in a block. Group 1 (n=29) had paraffin bath therapy (5 times per week, for 3-week duration) for both hands. Group 2 (n=27) was the control group. All patients were informed about joint-protection techniques, and paracetamol intake was recorded. The primary outcome measures were pain (at last 48h) at rest and during activities of daily living (ADL), assessed with a visual analog scale (0-10cm) at 12 weeks. The secondary outcome measures were the Australian Canadian Osteoarthritis Hand Index (AUSCAN) and the Dreiser Functional Index (DFI), used for subjective functional evaluation, loss of range of motion (ROM), grip and pinch strength, painful and tender joint counts, and paracetamol intake. A researcher blind to group allocation recorded the measures for both hands at baseline, 3 weeks, and 12 weeks at the hospital setting. At baseline, there were no significant differences between groups in any of the parameters (P>.05). After treatment, the paraffin group exhibited significant improvement in pain at rest and during ADL, ROM of the right hand, and pain and stiffness dimensions of the AUSCAN (P.05). The control group showed a significant deterioration in right hand grip and bilateral lateral pinch and right chuck pinch strength (Pparaffin group (Pparaffin group were significantly higher than the control group at 12 weeks (PParaffin bath therapy seemed to be effective both in reducing pain and tenderness and maintaining muscle strength in hand osteoarthritis.

    IMPORTANCE The management of patients with unilateral acute vestibular neuritis (VN) has not been established to date. OBJECTIVE To compare the use of vestibular exercises vs corticosteroid therapy in the recovery of patients with acute VN. DESIGN, SETTING, AND PARTICIPANTS Prospective, single-blind, randomized clinical trial at a primary referral center. Among all patients with acute vertigo, those having VN were eligible for inclusion in the study. INTERVENTIONS Forty patients with acute VN were randomly assigned to perform vestibular exercises or to receive corticosteroid therapy. After a baseline examination, follow-up evaluations were performed at 1, 6, and 12 months. MAIN OUTCOMES AND MEASURES Efficacy outcomes included clinical, canal, and otolith recovery. Scores on the European Evaluation of Vertigo Scale and the Dizziness Handicap Inventory were used for the evaluation of clinical recovery. Findings of caloric irrigation and vestibular evoked myogenic potentials indicated canal and otolith improvement, respectively. RESULTS Comparing the 2 treatment groups, no statistically significant differences were found in clinical, canal, or otolith recovery. At the 6-month examination, the number of patients with complete disease resolution in the corticosteroids group was significantly higher than that in the vestibular exercises group. However, at the end of the follow-up period, 45%(9 of 20) of patients in the vestibular exercises group and 50% (10 of 20) of patients in the corticosteroids group had complete disease resolution (P > .05). CONCLUSIONS AND RELEVANCE Treating patients who have acute VN with vestibular exercises seems equivalently effective as treating them with corticosteroid therapy in clinical, caloric, and otolith recovery. Corticosteroid therapy seems to enhance earlier complete acute VN resolution, with no added benefit in the long-term prognosis.

    Developmental assessment is a core paediatric competency, but research demonstrates teaching gaps. This single-blinded, randomised controlled study compares three teaching approaches to developmental assessment in a large group setting based on a student's self-perception and objective competency assessment. Students were randomised into one of the following: ▸ a didactic lecture followed by self-study with online resources (control group), ▸ a didactic lecture and small group tutorial (small group) ▸ a combined didactic lecture and interactive component using audio-visual equipment (Interactive Developmental Teaching-IDT group). Competency scores (based on the Royal College of Paediatrics and Child Health (RCPCH) scoring system, adapted for undergraduates), mean scores of self-reported confidence and degree of motivation were compared between groups. 114 students participated. Statistically significant difference between mean assessment scores was demonstrated for the small group (38.0; 95% CI 36.5 to 39.6) and the IDT group (37.9; 95% CI 36.5 to 39.4) compared to the control group (34.8; 95% CI 33.2 to 36.4). Students' self-reported confidence, acquisition of knowledge and degree of motivation to practice was higher in IDT and small groups compared to the didactically taught control group. Teaching costs, if measured by trainer's time, were one-fifth in the IDT group compared to the small group teaching. The IDT is an effective teaching method in large groups, improves competencies compared to didactic lecturing, and is as effective as small group teaching. Adoption of the IDT appears to facilitate learning and can be easily delivered with falling ratios of teachers to students. Published by the BMJ Publishing Group Limited.

    Full Text Available BACKGROUND: Previous studies suggest that electroacupuncture possesses therapeutic benefits for depressive disorders. The purpose of this study was to determine whether dense cranial electroacupuncture stimulation (DCEAS could enhance the antidepressant efficacy in the early phase of selective serotonin reuptake inhibitor (SSRI treatment of major depressive disorder (MDD. METHODS: In this single-blind, randomized, controlled study, patients with MDD were randomly assigned to 9-session DCEAS or noninvasive electroacupuncture (n-EA control procedure in combination with fluoxetine (FLX for 3 weeks. Clinical outcomes were measured using the 17-item Hamilton Depression Rating Scale (HAMD-17, Clinical Global Impression-severity (CGI-S, and Self-rating Depression Scale (SDS as well as the response and remission rates. RESULTS: Seventy-three patients were randomly assigned to n-EA (n = 35 and DCEAS (n = 38, of whom 34 in n-EA and 36 in DCEAS group were analyzed. DCEAS-treated patients displayed a significantly greater reduction from baseline in HAMD-17 scores at Day 3 through Day 21 and in SDS scores at Day 3 and Day 21 compared to patients receiving n-EA. DCEAS intervention also produced a higher rate of clinically significant response compared to n-EA procedure (19.4% (7/36 vs. 8.8% (3/34. The incidence of adverse events was similar in the two groups. CONCLUSIONS: DCEAS is a safe and effective intervention that augments the antidepressant efficacy. It can be considered as an additional therapy in the early phase of SSRI treatment of depressed patients. TRIAL REGISTRATION: Controlled-Trials.com ISRCTN88008690.

    In this study, we investigated the effects of group assertiveness training on assertiveness, social anxiety and satisfaction with interpersonal communication among patients with chronic schizophrenia. Only limited studies highlighted the effectiveness of group assertiveness training among inpatients with schizophrenia. Given the lack of group assertiveness training among patients with schizophrenia, further development of programmes focusing on facilitating assertiveness, self-confidence and social skills among inpatients with chronic schizophrenia is needed. This study used a prospective, randomized, single-blinded, parallel-group design. This study employed a prospective, randomized, parallel-group design. Seventy-four patients were randomly assigned to experimental group receiving 12 sessions of assertiveness training, or a supportive control group. Data collection took place for the period of June 2009-July 2010. Among patients with chronic schizophrenia, assertiveness, levels of social anxiety and satisfaction with interpersonal communication significantly improved immediately after the intervention and at the 3-month follow-up in the intervention group. The results of a generalized estimating equation (GEE) indicated that: (1) assertiveness significantly improved from pre- to postintervention and was maintained until the follow-up; (2) anxiety regarding social interactions significantly decreased after assertiveness training; and (3) satisfaction with interpersonal communication slightly improved after the 12-session intervention and at the 3-month follow-up. Assertivenss training is a non-invasive and inexpensive therapy that appears to improve assertiveness, social anxiety and interpersonal communication among inpatients with chronic schizophrenia. These findings may provide a reference guide to clinical nurses for developing assertiveness-training protocols. © 2013 Blackwell Publishing Ltd.

    Twenty-three lots of five antithrombin III (AT III) concentrates from four manufacturers were analyzed in a single-blind study. All the preparations had been virus-inactivated by pasteurization, and one concentrate had also been treated with solvent/detergent (S/D). AT III activities were determined using two thrombin-based and one factor Xa-based chromogenic substrate assays. AT III antigen was measured by kinetic nephelometry. All AT III assays were tested against the first international reference preparation coded 72/1. In addition, AT III was characterized by crossed immunoelectrophoresis in the presence of heparin and by gel filtration. The following were quantified: heparin cofactor II activity and antigen content, heparin activity, thrombin-AT III complexes, AT III-protease complexes, total protein, albumin, immunoglobulins, glucose and pH. The AT III concentrates differed markedly in terms of their purity and potency. The specific activities of AT III and the ratios of AT III activity to antigen content ranged from 3.4 to 6.9 and from 0.63 to 0.84, respectively. The highest values were found in five lots of the concentrate that had been treated by both pasteurization and S/D. This preparation was the only one that was virtually free of denaturated AT III, as judged by crossed immunoelectrophoresis. Marked batch-to-batch variation in AT III potencies was found in two out of the five preparations analyzed. In two out of five lots from one manufacturer, the measured potencies were more than 10% lower than the declared potencies.(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available Objective: Safoof-e-Pathar phori (SPP, a unani polyherbomineral formulation, used for antilithiatic activity since long time. This study was aimed to evaluate the clinical efficacy of SPP in adult human patients with urolithiasis. The study was a randomized, placebo-controlled, and single-blind, clinical trial. Materials and Methods: Forty-five patients who have stone size below 15 mm in the age group of 15-55 years with diagnosis of calcium oxalate renal calculi were taken in the study. Out of which, only 30 patients fulfilled the criteria and completed the study. Twenty patients received SPP (Group I and ten patients were given placebo (Group II for 2 months. The patients were investigated for routine, hemogram, blood urea, serum creatinine, calcium, phosphorus, serum glutamic oxaloacetic transaminase, serum glutamic pyruvic transaminase, and uric acid levels at definite time intervals. Similarly, routine and microscopic urine examination was done with radio-imaging KUB and ultrasound KUB examination, etc., which were repeated on completion of the study. Results: All patients received the same dosage of SPP or placebo for a 2-month period. On starting SPP, symptomatic relief was reported by patients. The disappearance of stones was noted in patients as confirmed by X-ray KUB and Ultrasound KUB examination. Totally, 56.67% of patients showed reduction in size of stone and 49.31% showed litho expulsive effect. Conclusion: The use of SPP in the treatment of calcium oxalate stone as noninvasive remedy for the urolithiatic patients is validated and proved. Since the dose of formulation is too high, further study on dose reduction followed by preclinical evaluation may be attempted for development of scientific data.

    Complementary alternative medicine, such as shiatsu, can represent a suitable treatment for primary headaches. However, evidence-based data about the effect of combining shiatsu and pharmacological treatments are still not available. Therefore, we tested the efficacy and safety of combining shiatsu and amitriptyline to treat refractory primary headaches in a single-blind, randomized, pilot study. Subjects with a diagnosis of primary headache and who experienced lack of response to ≥2 different prophylactic drugs were randomized in a 1:1:1 ratio to receive shiatsu plus amitriptyline, shiatsu alone, or amitriptyline alone for 3 months. Primary endpoint was the proportion of patients experiencing ≥50%-reduction in headache days. Secondary endpoints were days with headache per month, visual analogue scale, and number of pain killers taken per month. After randomization, 37 subjects were allocated to shiatsu plus amitriptyline (n = 11), shiatsu alone (n = 13), and amitriptyline alone (n = 13). Randomization ensured well-balanced demographic and clinical characteristics at baseline. Although all the three groups improved in terms of headache frequency, visual analogue scale score, and number of pain killers (p < 0.05), there was no between-group difference in primary endpoint (p = ns). Shiatsu (alone or in combination) was superior to amitriptyline in reducing the number of pain killers taken per month (p < 0.05). Seven (19%) subjects reported adverse events, all attributable to amitriptyline, while no side effects were related with shiatsu treatment. Shiatsu is a safe and potentially useful alternative approach for refractory headache. However, there is no evidence of an additive or synergistic effect of combining shiatsu and amitriptyline. These findings are only preliminary and should be interpreted cautiously due to the small sample size of the population included in our study. Trial registration 81/2010 (Ethical Committee, S.

  4. Optical Sectioning and High Resolution in Single-Slice Structured Illumination Microscopy by Thick Slice Blind-SIM Reconstruction.

    Directory of Open Access Journals (Sweden)

    Aurélie Jost

    Full Text Available The microscope image of a thick fluorescent sample taken at a given focal plane is plagued by out-of-focus fluorescence and diffraction limited resolution. In this work, we show that a single slice of Structured Illumination Microscopy (two or three beam SIM data can be processed to provide an image exhibiting tight sectioning and high transverse resolution. Our reconstruction algorithm is adapted from the blind-SIM technique which requires very little knowledge of the illumination patterns. It is thus able to deal with illumination distortions induced by the sample or illumination optics. We named this new algorithm thick slice blind-SIM because it models a three-dimensional sample even though only a single two-dimensional plane of focus was measured.

    Full Text Available Background: Auricular acupressure is one of the traditional health care treatments in oriental medicine. Approximately, 30~40% of the cancer patients have said to be suffering from insomnia and half of them having chronic and severe insomnia at the same time. Insomnia caused cancer patients feel more pain, fatigue, depression and anxiety and it sometimes let the power to have the best of cancer pull down. Objective: To investigate how effective the auricular acupressure treatment to cancer patients suffering from insomnia. Methods: We recruited participants from East-West Cancer Center of Daejeon University. Finally, of the people whose age range from 20 to 75, 12 patients who got less than 40 points from the score of Oh's sleeping score (OSS were recruited. Single-blind, randomized pilot study was performed. The treatment group received auricular acupressure treatment (AAT on active points and the control group had received sham acupressure treatment (SAT for five times. Sleep parameters were checked by using OSS and numeric rating scale (NRS. We checked the scale everytime, both before and after treatment. We analyzed the data statistically by using independent T-test, paired T-test and analysis of variance (ANOVA test. (p<0.05 Results: Twelve cancer patients participated in this pilot study and there was no significant difference between control and treatment group. Only 7 of them had completed the whole treatment process, 4 patients of AAT group and 3 participants of SAT. The OSS of AAT group had increased from 34.0± 4.3 to 39.5±3.1 and that of SAT group had increased from 38.3±3.5 to 40.0±0.0. There was no significant difference between them. The NRS of AAT group had increased from 6.3±2.9 to 4.8±2.1 and that of SAT group had increased from 7.0±1.0 to 5.0±2.6. No significant difference was observed between them. Conclusion: Although both groups did not show significant differences, most of the experimental participants showed

    To evaluate the efficacy of therapist guided internet based cognitive behavioural therapy (CBT) programme for body dysmorphic disorder (BDD-NET) compared with online supportive therapy. A 12 week single blind parallel group randomised controlled trial. Academic medical centre. 94 self referred adult outpatients with a diagnosis of body dysmorphic disorder and a modified Yale-Brown obsessive compulsive scale (BDD-YBOCS) score of ≥ 20. Concurrent psychotropic drug treatment was permitted if the dose had been stable for at least two months before enrolment and remained unchanged during the trial. Participants received either BDD-NET (n=47) or supportive therapy (n=47) delivered via the internet for 12 weeks. The primary outcome was the BDD-YBOCS score after treatment and follow-up (three and six months from baseline) as evaluated by a masked assessor. Responder status was defined as a ≥ 30% reduction in symptoms on the scale. Secondary outcomes were measures of depression (MADRS-S), global functioning (GAF), clinical global improvement (CGI-I), and quality of life (EQ5D). The six month follow-up time and all outcomes other than BDD-YBOCS and MADRS-S at 3 months were not pre-specified in the registration at clinicaltrials.gov because of an administrative error but were included in the original trial protocol approved by the regional ethics committee before the start of the trial. BDD-NET was superior to supportive therapy and was associated with significant improvements in severity of symptoms of body dysmorphic disorder (BDD-YBOCS group difference -7.1 points, 95% confidence interval -9.8 to -4.4), depression (MADRS-S group difference -4.5 points, -7.5 to -1.4), and other secondary measures. At follow-up, 56% of those receiving BDD-NET were classed as responders, compared with 13% receiving supportive therapy. The number needed to treat was 2.34 (1.71 to 4.35). Self reported satisfaction was high. CBT can be delivered safely via the internet to patients with body

    Despite advances in cancer diagnosis and treatment have significantly improved survival rates, patients post-treatment-related health needs are often not adequately addressed by current health services. The aim of the Women's Wellness after Cancer Program (WWACP), which is a digitised multimodal lifestyle intervention, is to enhance health-related quality of life in women previously treated for blood, breast and gynaecological cancers. A single-blinded, multi-centre randomized controlled trial recruited a total of 351 women within 24 months of completion of chemotherapy (primary or adjuvant) and/or radiotherapy. Women were randomly assigned to either usual care or intervention using computer-generated permuted-block randomisation. The intervention comprises an evidence-based interactive iBook and journal, web interface, and virtual health consultations by an experienced cancer nurse trained in the delivery of the WWACP. The 12 week intervention focuses on evidence-based health education and health promotion after a cancer diagnosis. Components are drawn from the American Cancer Research Institute and the World Cancer Research Fund Guidelines (2010), incorporating promotion of physical activity, good diet, smoking cessation, reduction of alcohol intake, plus strategies for sleep and stress management. The program is based on Bandura's social cognitive theoretical framework. The primary outcome is health-related quality of life, as measured by the Functional Assessment of Cancer Therapy-General (FACT-G). Secondary outcomes are menopausal symptoms as assessed by Greene Climacteric Scale; physical activity elicited with the Physical Activity Questionnaire Short Form (IPAQ-SF); sleep measured by the Pittsburgh Sleep Quality Index; habitual dietary intake monitored with the Food Frequency Questionnaire (FFQ); alcohol intake and tobacco use measured by the Australian Health Survey and anthropometric measures including height, weight and waist-to-hip ratio.

    Chitosan is a dietary fibre which acts by reducing fat absorption and thus used as a means for controlling weight. Weight loss clinical trial outcomes, however, have contradictory results regarding its efficacy. The primary objective of the present study was to evaluate the efficacy and safety of a chitosan from fungal origin in treatment of excess weight in the absence of dietary restrictions. A phase IV, randomised, multicentre, single-blind, placebo-controlled, clinical study was conducted by administering chitosan capsules (500 mg, five/day) and indistinguishable placebo capsules as daily supplements to 96 overweight and obese subjects for 90 days. The study participants were divided in 2:1 ratio to receive either chitosan (n = 64) or placebo (n = 32). Efficacy was assessed by measuring body weight, body composition parameters, anthropometric measurements, HbA1C level and lipid profile at day 45 and day 90. Also, short form-36 quality of life (QoL) questionnaire was assessed to evaluate improvement in life-style and dietary habits were recorded for calorie intake. Safety was assessed by evaluating safety parameters and monitoring adverse events. The mean changes in body weight were -1.78 ± 1.37 kg and -3.10 ± 1.95 kg at day 45 and day 90 respectively in chitosan group which were significantly different (p reduction in body composition and anthropometric parameters together with improvement in QoL score. Chitosan was also able to reduce HbA1C levels (below 6 %) in subjects who had initial higher values. The mean caloric intake shows that there was no change in dietary habits of subjects in both groups. Lipid levels were unaffected and all adverse events were mild in nature and unrelated to study treatment. Chitosan from fungal origin was able to reduce the mean body weight up to 3 kg during the 90 day study period. Together with this, there was also improvement in body composition, anthropometric parameters and HbA1C, reflecting overall benefits for the

    This study aimed to determine the safety and tolerability of trofinetide and to evaluate efficacy measures in adolescent and adult females with Rett syndrome, a serious and debilitating neurodevelopmental condition for which no therapies are available for its core features. This was an exploratory, phase 2, multicenter, double-blind, placebo-controlled, dose-escalation study of the safety and tolerability of trofinetide in 56 adolescent and adult females with Rett syndrome. Subjects were randomly assigned in a 2:1 ratio to 35 mg/kg twice daily of trofinetide or placebo for 14 days; 35 mg/kg twice daily or placebo for 28 days; or 70 mg/kg twice daily or placebo for 28 days. Safety assessments included adverse events, clinical laboratory tests, vital signs, electrocardiograms, physical examinations, and concomitant medications. Efficacy measurements were categorized into four efficacy domains, which related to clinically relevant, phenotypic dimensions of impairment associated with Rett syndrome. Both 35 mg/kg and 70 mg/kg dose levels of trofinetide were well tolerated and generally safe. Trofinetide at 70 mg/kg demonstrated efficacy compared with placebo based on prespecified criteria. Trofinetide was well tolerated in adolescent and adult females with Rett syndrome. Although this study had a relatively short duration in a small number of subjects with an advanced stage of disease, consistent efficacy trends at the higher dose were observed in several outcome measures that assess important dimensions of Rett syndrome. These results represented clinically meaningful improvement from the perspective of the clinicians as well as the caregivers. Copyright © 2017 Elsevier Inc. All rights reserved.

    Single crystals of hybrid perovskites have shown remarkably improved physical properties compared to their polycrystalline film counterparts, underscoring their importance in the further development of advanced semiconductor devices. Here we present a new method of sizeable CH3NH3PbCl3 single crystal growth based on retrograde solubility behavior of hybrid perovskites. We show, for the first time, the energy band structure, charge-carrier recombination and transport properties of single crystal CH3NH3PbCl3. The chloride-based perovskite crystals exhibit trap-state density, charge carriers concentration, mobility and diffusion length comparable with the best quality crystals of methylammonium lead iodide or bromide perovskites reported so far. The high quality of the crystal along with its suitable optical bandgap enabled us to design and build an efficient visible-blind UV-photodetector, demonstrating the potential of this material to be employed in optoelectronic applications.

    Ultraviolet (UV) studies in astronomy, cosmology, planetary studies, biological and medical applications often require precision detection of faint objects and in many cases require photon-counting detection. We present an overview of two approaches for achieving photon counting in the UV. The first approach involves UV enhancement of photon-counting silicon detectors, including electron multiplying charge-coupled devices and avalanche photodiodes. The approach used here employs molecular beam epitaxy for delta doping and superlattice doping for surface passivation and high UV quantum efficiency. Additional UV enhancements include antireflection (AR) and solar-blind UV bandpass coatings prepared by atomic layer deposition. Quantum efficiency (QE) measurements show QE > 50% in the 100–300 nm range for detectors with simple AR coatings, and QE ≅ 80% at ~206 nm has been shown when more complex AR coatings are used. The second approach is based on avalanche photodiodes in III-nitride materials with high QE and intrinsic solar blindness. PMID:27338399

    Shoulder pain can be difficult to treat due to its complex anatomic structure, and different treatment methods can be used. We aimed to examine the efficacy of photobiomodulation therapy (PBMT) and suprascapular nerve (SSN)-pulsed radiofrequency (RF) therapy. In this prospective, randomized, controlled, single-blind study, 59 patients with chronic shoulder pain due to impingement syndrome received PBMT (group H) or SSN-pulsed RF therapy (group P) in addition to exercise therapy for 14 sessions over 2 weeks. Records were taken using visual analog scale (VAS), Shoulder Pain and Disability Index (SPADI), and Nottingham Health Profile (NHP) scoring systems for pretreatment (PRT), posttreatment (PST), and PST follow-up at months 1, 3, and 6. There was no statistically significant difference in initial VAS score, SPADI, and NHP values between group H and group P (p > 0.05). Compared to the values of PRT, PST, and PST at months 1, 3, and 6, VAS, SPADI, and NHP values were statistically significantly lower in both groups (p shoulder pain. PBMT seems to be advantageous compared to SSN-pulsed RF therapy, as it is a noninvasive method.

    Thiazide diuretics are associated with increased risk of diabetes mellitus. This risk may arise from K(+)-depletion. We hypothesised that a K(+)-sparing diuretic will improve glucose tolerance, and that combination of low-dose thiazide with K(+)-sparing diuretic will improve both blood pressure reduction and glucose tolerance, compared to a high-dose thiazide. This is a parallel-group, randomised, double-blind, multicentre trial, comparing hydrochlorothiazide 25-50 mg, amiloride 10-20 mg and combination of both diuretics at half these doses. A single-blind placebo run-in of 1 month is followed by 24 weeks of blinded active treatment. There is forced dose-doubling after 3 months. The Primary end point is the blood glucose 2 h after oral ingestion of a 75 g glucose drink (OGTT), following overnight fasting. The primary outcome is the difference between 2 h glucose at weeks 0, 12 and 24. Secondary outcomes include the changes in home systolic blood pressure (BP) and glycated haemoglobin and prediction of response by baseline plasma renin. Eligibility criteria are: age 18-79, systolic BP on permitted background treatment ≥ 140 mm Hg and home BP ≥ 130 mm Hg and one component of the metabolic syndrome additional to hypertension. Principal exclusions are diabetes, estimated-glomerular filtration rate 200 mm Hg or DBP >120 mm Hg (box 2). The sample size calculation indicates that 486 patients will give 80% power at α=0.01 to detect a difference in means of 1 mmol/L (SD=2.2) between 2 h glucose on hydrochlorothiazide and comparators. PATHWAY-3 was approved by Cambridge South Ethics Committee, number 09/H035/19. The trial results will be published in a peer-reviewed scientific journal.

    Intravesical instillation of liposomal formulated botulinum toxin A (lipotoxin) has shown therapeutic effects as treatment of refractory overactive bladder without needle injections. We assessed lipotoxin to treat refractory interstitial cystitis/bladder pain syndrome. This 2-center, double-blind, randomized, placebo controlled, physician initiated study enrolled patients with refractory interstitial cystitis/bladder pain syndrome. A total of 31 patients were assigned to intravesical instillation of lipotoxin (onabotulinumtoxinA 200 U with 80 mg sphingomyelin), 28 were assigned to onabotulinumtoxinA 200 U in normal saline and 31 were assigned to normal saline alone. The primary end point was the average change in O'Leary-Sant symptom scores, including ICSI (Interstitial Cystitis Symptom Index) and ICPI (Interstitial Cystitis Problem Index) between baseline and 4 weeks after treatment. Other end points included the average changes in a 3-day voiding diary, a visual analog scale for pain and a global response assessment of patient satisfaction. Improvements in the pain scale and O'Leary-Sant symptom scores occurred in all 3 groups by 4 weeks after treatment. Lipotoxin instillation was associated with a statistically significant decrease in O'Leary-Sant symptom scores (mean ± SD 7.38 ± 8.75), ICSI (4.00 ± 4.28), ICPI (3.35 ± 5.11) and the visual analog scale pain scale (1.64 ± 2.52), and an increase in the global response assessment (1.35 ± 1.28). However, there was no difference in improvement among the 3 groups. No significant adverse events were found in any group. Lipotoxin failed to demonstrate a positive proof of concept compared to onabotulinumtoxinA or placebo. However, a single intravesical instillation of lipotoxin was associated with decreased interstitial cystitis/bladder pain syndrome symptoms compared to baseline in patients with moderate to severe interstitial cystitis/bladder pain syndrome. The effect was likely due to a significant placebo

    The aim of the present study was to assess the effectiveness of belly dance as a treatment option for patients with fibromyalgia. Eighty female patients with fibromyalgia between 18 to 65 years were randomly allocated to a dance group (n=40) and control group (n=40). Patients in the dance group underwent 16 weeks of belly dance twice a week, while the patients in the control group remained on a waiting list. The patients were evaluated with regard to pain (VAS), function (6MWT), quality of life (FIQ and SF-36), depression (Beck Inventory), anxiety (STAI) and self-image (BDDE). Evaluations were carried out at baseline, 16 weeks and 32 weeks by a blinded assessor. The dance group achieved significant improvements in VAS for pain (pfibromyalgia to reduce pain and improve functional capacity, quality of life and self-image.

    The purpose of this study was to elucidate the effects of a dual-coated probiotic supplement (Duolac Care) on symptoms of diarrhea-predominant irritable bowel syndrome in a randomized double-blind clinical trial. Fifty subjects with diarrhea-predominant irritable bowel syndrome were randomly assigned to either the non-coating group or the dual-coating group in order to receive two capsules per day of multi-species probiotics containing 5 billion bacteria per capsule for 4 weeks. Data from an adequate relief questionnaire were used in assessment of primary outcome. Daily records of stool frequencies and the Bristol stool scale, a weekly symptom diary using 100-mm visual analog scale, and Beck depression inventories were collected. Blood tests including blood cell counts, interleukin-10, tumor necrosis factor-alpha and inducible nitric oxide synthase, and regulatory T cells-CD4 + CD25 high T cells, CD4 + LAP + T cells and CD25 high  + LAP + T cells-were analyzed before and after the study. The shift of gut microbiota was investigated using a quantitative real-time polymerase chain reaction assay. Responses to the adequate relief questionnaire indicated significant improvement in overall discomfort in the dual-coating group and the ratio of normal stools to hard or watery stools had a better effect from dual-coated probiotics compared to non-coated probiotics. This may be due to a shift of intestinal microbiota, as our correlation analysis showed significant negative correlation between Bifidobacterium and urgency of defecation. Our result implies that dual-coating layers of probiotic supplement can be a candidate for treatment of diarrhea-predominant irritable bowel syndrome.

    2014-01-01

    The efficacy of adalimumab for the treatment of interstitial cystitis/bladder pain syndrome was investigated in a phase III, randomized, double-blind, placebo controlled, proof of concept study. Patients with interstitial cystitis/bladder pain syndrome were randomized to receive a loading dose of 80 mg subcutaneous adalimumab followed by 40 mg every 2 weeks or subcutaneous placebo for 12 weeks, and outcome measures were assessed. The incidence of adverse events was also assessed. Of a total of 43 patients 21 received adalimumab and 22 received placebo. Of the patients who received adalimumab, there was a statistically significant improvement demonstrated in the O'Leary-Sant Interstitial Cystitis Symptom and Problem Indexes (p = 0.0002), Interstitial Cystitis Symptom Index (p = 0.0011), Interstitial Cystitis Problem Index (p = 0.0002), and Pelvic Pain, Urgency, Frequency Symptom Scale (p = 0.0017) at 12 weeks compared to baseline. At 12 weeks 11 of 21 (53%) patients in the adalimumab group had a 50% or greater improvement in global response assessment (p ≤ 0.0001). There was not a statistically significant improvement in any outcome measure in patients receiving adalimumab compared to placebo. There were no significant adverse events. Adalimumab treatment resulted in a statistically significant improvement in outcome measures compared to baseline in patients with moderate to severe interstitial cystitis/bladder pain syndrome. Adalimumab failed to demonstrate positive proof of concept compared to placebo due to a significant placebo effect. Copyright © 2014 American Urological Association Education and Research, Inc.

    Rituximab could be an effective treatment for childhood-onset, complicated, frequently relapsing nephrotic syndrome (FRNS) and steroid-dependent nephrotic syndrome (SDNS). We investigated the efficacy and safety of rituximab in patients with high disease activity. We did a multicentre, double-blind, randomised, placebo-controlled trial at nine centres in Japan. We screened patients aged 2 years or older experiencing a relapse of FRNS or SDNS, which had originally been diagnosed as nephrotic syndrome when aged 1-18 years. Patients with complicated FRNS or SDNS who met all other criteria were eligible for inclusion after remission of the relapse at screening. We used a computer-generated sequence to randomly assign patients (1:1) to receive rituximab (375 mg/m(2)) or placebo once weekly for 4 weeks, with age, institution, treatment history, and the intervals between the previous three relapses as adjustment factors. Patients, guardians, caregivers, physicians, and individuals assessing outcomes were masked to assignments. All patients received standard steroid treatment for the relapse at screening and stopped taking immunosuppressive agents by 169 days after randomisation. Patients were followed up for 1 year. The primary endpoint was the relapse-free period. Safety endpoints were frequency and severity of adverse events. Patients who received their assigned intervention were included in analyses. This trial is registered with the University Hospital Medical Information Network clinical trials registry, number UMIN000001405. Patients were centrally registered between Nov 13, 2008, and May 19, 2010. Of 52 patients who underwent randomisation, 48 received the assigned intervention (24 were given rituximab and 24 placebo). The median relapse-free period was significantly longer in the rituximab group (267 days, 95% CI 223-374) than in the placebo group (101 days, 70-155; hazard ratio: 0·27, 0·14-0·53; pchildhood-onset, complicated FRNS and SDNS.

    Gambling disorder is a disabling illness experienced by 1% to 3% of adults. Pharmacologic management of gambling disorder has produced mixed results, with some but not all studies showing medication to be more effective than placebo. Ecopipam may offer promise for treating gambling disorder because of its antagonism of dopamine-1 receptors. Twenty-eight individuals with gambling disorder were enrolled and received ≥1 dose of oral ecopipam in an 8-week trial (1 week placebo lead-in, 6 weeks of medication (50 to 100 mg/d as needed), and 1 week follow-up. Participants were enrolled between September 2010 and June 2011 at 3 sites in the United States. Change from baseline to study endpoint on the Yale-Brown Obsessive Compulsive Scale Modified for Pathological Gambling (PG-YBOCS) was the primary outcome measure. Treatment was associated with statistically significant reductions in the PG-YBOCS total score (baseline score of 25.6 reduced to 14.0 at study endpoint; P>.001) and PG-YBOCS subscales (Thought-Urge and Behavior, P>.001). These findings suggest that pharmacologic targeting of the dopamine-1 receptor may be beneficial in gambling behavior. Placebo-controlled, double-blind studies are warranted to confirm these preliminary findings.

    Effect of thermal water with high mineral content on clinical parameters and quality of life of patients with chronic low back pain was studied. In this randomized controlled, single-blind, follow-up study, 60 patients with chronic low back pain were randomized into two groups. The treatment group received balneotherapy with thermal-mineral water, and the control group bathed in tap water. Changes of the followings were evaluated: visual analogue scale (VAS) for pain, range of motion for the lumbar spine, Oswestry index, EuroQol-5D and Short Form-36 questionnaires. In the treatment group, the mobility of the lumbar spine, the Oswestry index, the VAS scores and the EuroQoL-5D index improved significantly. SF-36 items improved significantly in the treated group compared with baseline except for two parameters. Our study demonstrated the beneficial effect of balneotherapy with thermal mineral versus tap water on clinical parameters, along with improvements in quality of life.

    Single-blind randomized, controlled clinical study. To evaluate, using kinematic gait analysis, the results obtained from gait training on a treadmill with body weight support versus those obtained with conventional gait training and physiotherapy. Thirty patients with sequelae from traumatic incomplete spinal cord injuries at least 12 months earlier; patients were able to walk and were classified according to motor function as ASIA (American Spinal Injury Association) impairment scale C or D. Patients were divided randomly into two groups of 15 patients by the drawing of opaque envelopes: group A (weight support) and group B (conventional). After an initial assessment, both groups underwent 30 sessions of gait training. Sessions occurred twice a week, lasted for 30 min each and continued for four months. All of the patients were evaluated by a single blinded examiner using movement analysis to measure angular and linear kinematic gait parameters. Six patients (three from group A and three from group B) were excluded because they attended fewer than 85% of the training sessions. There were no statistically significant differences in intra-group comparisons among the spatial-temporal variables in group B. In group A, the following significant differences in the studied spatial-temporal variables were observed: increases in velocity, distance, cadence, step length, swing phase and gait cycle duration, in addition to a reduction in stance phase. There were also no significant differences in intra-group comparisons among the angular variables in group B. However, group A achieved significant improvements in maximum hip extension and plantar flexion during stance. Gait training with body weight support was more effective than conventional physiotherapy for improving the spatial-temporal and kinematic gait parameters among patients with incomplete spinal cord injuries.

    Tourette's syndrome (TS) is a neurodevelopmental disorder typically defined by multiple motor tics and at least one sound tic, beginning in childhood or in adolescence. Handwriting is one of the most impaired school activities for TS patients because of the presence of tics that hamper learning processes. In this paper, we present a case of handwriting tics in a TS patient highlighting the main features.

    Early cognitive intervention is the only routine therapeutic approach used for amelioration of intellectual deficits in individuals with Down's syndrome, but its effects are limited. We hypothesised that administration of a green tea extract containing epigallocatechin-3-gallate (EGCG) would improve the effects of non-pharmacological cognitive rehabilitation in young adults with Down's syndrome. We enrolled adults (aged 16-34 years) with Down's syndrome from outpatient settings in Catalonia, Spain, with any of the Down's syndrome genetic variations (trisomy 21, partial trisomy, mosaic, or translocation) in a double-blind, placebo-controlled, phase 2, single centre trial (TESDAD). Participants were randomly assigned at the IMIM-Hospital del Mar Medical Research Institute to receive EGCG (9 mg/kg per day) or placebo and cognitive training for 12 months. We followed up participants for 6 months after treatment discontinuation. We randomly assigned participants using random-number tables and balanced allocation by sex and intellectual quotient. Participants, families, and researchers assessing the participants were masked to treatment allocation. The primary endpoint was cognitive improvement assessed by neuropsychologists with a battery of cognitive tests for episodic memory, executive function, and functional measurements. Analysis was on an intention-to-treat basis. This trial is registered with ClinicalTrials.gov, number NCT01699711. The study was done between June 5, 2012, and June 6, 2014. 84 of 87 participants with Down's syndrome were included in the intention-to-treat analysis at 12 months (43 in the EGCG and cognitive training group and 41 in the placebo and cognitive training group). Differences between the groups were not significant on 13 of 15 tests in the TESDAD battery and eight of nine adaptive skills in the Adaptive Behavior Assessment System II (ABAS-II). At 12 months, participants treated with EGCG and cognitive training had significantly higher

    Alcohol use disorders (AUDs) and mood disorders commonly co-occur, and are associated with a range of negative outcomes for patients. Mobile phone technology has the potential to provide personalised support for such patients and potentially improve outcomes in this difficult-to-treat cohort. The aim of this study is to examine whether receiving supporting SMS text messages, following discharge from an inpatient dual diagnosis treatment programme, has a positive impact on mood and alcohol abstinence in patients with an AUD and a comorbid mood disorder. The present study is a single-blind randomised controlled trial. Patients aged 18-70 years who meet the criteria for both alcohol dependency syndrome/alcohol abuse and either major depressive disorder or bipolar disorder according to the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders IV Axis I will be randomised to receive twice-daily supportive SMS text messages for 6 months plus treatment as usual, or treatment as usual alone, and will be followed-up at 3, 6, 9 and 12 months postdischarge. Primary outcome measures will include changes from baseline in cumulative abstinence duration, which will be expressed as the proportion of days abstinent from alcohol in the preceding 90 days, and changes from baseline in Beck Depression Inventory scores. The trial has received full ethical approval from the St. Patrick's Hospital Research Ethics Committee (protocol 13/14). Results of the trial will be disseminated through peer-reviewed journal articles and at academic conferences.

    This study was designed to evaluate the efficacy and safety of fulranumab, a fully human monoclonal antibody directed against nerve growth factor (NGF), for pain relief in patients with interstitial cystitis/bladder pain syndrome (IC/BPS). In this multicenter, double-blind study, adults with IC/BPS (i.e., interstitial cystitis symptom index [ICSI] total score ≥8) accompanied by chronic, moderate-to-severe pain were randomized to fulranumab 9 mg or matching placebo, administered subcutaneously at weeks 1, 5, and 9. The primary efficacy endpoint was change from baseline to study endpoint (week 12 or at withdrawal) in average daily pain intensity score. Key secondary endpoints included change from baseline to study endpoint in worst pain intensity score, ICSI total score, Pelvic Pain and Urgency/Frequency total score, Patient Perception of Bladder Condition score, and global response assessment. This study was terminated prematurely based on concern that this class may be associated with rapidly progressing osteoarthritis or osteonecrosis. Thirty-one patients (of the targeted 70 patients) were randomized, 17 to placebo and 14 to fulranumab, with 15 and 10 patients, respectively, receiving all 3 doses of double-blind treatment. In ANOVA analyses, there was no statistically significant difference between treatment groups for the primary endpoint (LS mean difference [95% CI] vs. placebo, -0.2 [-1.52, 1.10]) or any of the secondary endpoints. Fulranumab was well tolerated, with no patient discontinuing due to an adverse event or experiencing a joint-related serious adverse event over a 26-week follow-up period. No events related to the neurologic or motor systems were reported. Efficacy was not demonstrated in the present study with the single dose tested and a limited sample size, leading to lack of statistical power. These findings do not exclude the possibility that fulranumab would provide clinical benefit in a larger study and/or specific populations (phenotypes

    The International Diabetes Federation (IDF) proposed a novel definition of the metabolic syndrome (MS) in 2005, which designated central obesity as mandatory. The new National Cholesterol Education Program (NCEP) version, announced by the American Heart Association and National Heart Lung and Blood Institute in October 2005, did not favor any of the five components. We set out to compare the cardiovascular profiles of patients cross-defined by these two definitions to shed light on the differential meanings of the two. We analyzed data from 2608 non-institutionalized adults (> or =19 years old) in the National Nutrition and Health Survey in Taiwan, who had complete data for the five MS defining components. Both definitions adopted lower cut-points for fasting glucose and race-specific cut-points for waist circumference. Under the IDF's and new NCEP's definitions, the MS prevalence was 6.2% and 11.6% in men and 12.6% and 16.5% in women, respectively. Although the two definitions had high agreement, IDF failed to pick up approximately 4% to 5% of people with more than three MS component disorders but a waist circumference less than the cut-point. Subjects whose physical conditions only satisfied NCEP's definition had similar or worse metabolic profiles than those whose conditions satisfied both IDF's definition and the new NCEP's definition. The IDF definition would fail to identify a portion of people who have more than three MS component disorders but a small waistline. Further research and discussion are needed on whether and how to implement the IDF's definition.

    Background: This study examined the effects of dry needling on chronic heel pain due to plantar fasciitis. Methods: During this single-blinded clinical trial, 20 eligible patients were randomized into two groups: A case group treated with dry needling and a control group. Patients’ plantar pain severity, (using modified visual analog scale [VAS] scoring system), range of motion of ankle joint in dorsiflexion [ROMDF] and plantar extension[ROMPE] and foot function index (using standard questionnaires of SEM5 and MDC7) were assessed at baseline, four weeks after intervention and four weeks after withdrawing treatment. Independent sample t-test, Mann-Whitney U test, paired t-test, Wilcoxon signed rank tests, and chi square test were used for data analysis. Results: The mean VAS scores in the case group was significantly lower than the control group after four weeks of intervention (pdry needling, by improving the severity of heel pain, can be used as a good alternative option before proceeding to more invasive therapies of plantar fasciitis.

    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.

    Individuals show high variability in body weight responses to exercise training. Expectations and motivation towards effects of exercise on body weight might influence eating behaviour and could conceal regulatory mechanisms. We conducted 2 single-blind exercise trials (4 weeks (study 1) and 8 weeks (study 2)) with concealed objectives and exclusion of individuals with weight loss intention. Circuit exercise training programs (3 times a week (45-90 min), intensity 50%-90% peak oxygen uptake for 4 and 8 weeks) were conducted. Thirty-four females finished the 4-week intervention and 36 females the 8-week intervention. Overweight/obese (OV/OB) and lean female participants' weight/body composition responses were assessed and fasting and postprandial appetite hormone levels (PYY, insulin, amylin, leptin, ghrelin) were measured before and after the intervention for understanding potential contribution to individuals' body weight response to exercise training (study 2). Exercise training in both studies did not lead to a significant reduction of weight/body mass index (BMI) in the participants' groups; however, lean participants gained muscle mass. Appetite hormones levels were significantly (p training did not lead to weight loss in female participants, while a considerable proportion of variance in body weight response to training could be explained by individuals' appetite hormone levels and BMI.

    Full Text Available We aimed to test the hypothesis that Minimally Invasive Video-assisted Thyroidectomy (MIVAT affords comparable safety and efficacy as to the open conventional surgery, when dealing with patients with unilateral thyroid nodules or follicular lesions, in terms of cosmetic results, intraoperative and postoperative complications, postoperative pain and hospital stay. Materials And Methods: This was a single-blinded randomised controlled trial comparing the MIVAT with conventional thyroidectomy. The primary endpoints of the study were measurement of postoperative pain after 24 and 48 hours from operation and self-rated patient satisfaction with cosmetic outcome three months postoperatively. The secondary outcome measures were operative time, incidence of temporary and permanent recurrent laryngeal nerve injury, postoperative haematoma formation, length of incision, and duration of hospital stay. Results: Operative time was significantly less with open thyroidectomy than with MIVAT, while MIVAT was associated with less pain 24 hours postoperatively. Blood loss did not reach significance between procedures. Comparisons between the two procedures with regard to pain scores after 24 and 48 hours, respectively, depicted statistically significant differences in favour of the MIVAT after 24 hours. MIVAT was associated with less scarring and more satisfactory cosmetic results. There were statistically no significant differences between both procedures for the presence of transient recurrent laryngeal nerve palsy and hypoparathyroidism. Conclusions: MIVAT is a safe procedure that produces outcomes, in view of short-term adverse events, similar to those of open thyroidectomy, and is superior in terms of immediate postoperative pain and cosmetic results.

    Many family caregivers of persons with dementia (PWD) are unable to participate in community center-based caregiver support services because of logistical constraints. This study evaluated the effectiveness of a telephone-delivered psychoeducational intervention for family caregivers of PWD in alleviating caregiver burden and enhancing caregiving self-efficacy. In a single-blinded randomized controlled trial, 38 family caregivers of PWD were randomly allocated into an intervention group or a control group. The intervention group received psychoeducation from a registered social worker over the phone for 12 sessions. Caregivers in the control group were given a DVD containing educational information about dementia caregiving. Outcomes of the intervention were measured by the Chinese versions of the Zarit Burden Interview and the Revised Scale for Caregiving Self-efficacy. Mann-Whitney U tests were used to compare the differences between the intervention and control groups. The level of burden of caregivers in the intervention group reduced significantly compared with caregivers in the control group. Caregivers in the intervention group also reported significantly more gain in self-efficacy in obtaining respite than the control group. A structured telephone intervention can benefit dementia caregivers in terms of self-efficacy and caregiving burden. The limitations of the research and recommendations for intervention are discussed.

    To examine the pattern and extent of cardiovascular developmental alterations among children conceived by assisted reproductive technology (ART) and its association with potential confounders. The present study was a prospective single-blind pilot design lasting 15 months. The ART group was recruited by a non-random, consecutive sample on the basis of the unique personal identification number assigned to ART children, whereas spontaneous conception controls were recruited by a population-based random sample from the same hospital by age. Echocardiography was available for the measurement of 128 ART children and 100 controls with respect to cardiovascular geometric morphology and cardiac function. The majority of cardiac geometric morphology parameters were comparable among the study groups (P>0.05), except for significant increases in left ventricular (LV) relative wall thickness (P=0.038), LV mass index (P=0.005) and LV remodeling index (P=0.005) in ART children after adjustment for age, gender, body surface area and heart rate. The results showed similarity in LV systolic function characterized by ejection fraction (P=0.140) and shortening fraction (P=0.167) between the groups. However, ART children had a significant tendency toward a decrease in mitral A (P=0.008) and mitral E' (P=0.012) compared with controls after adjusting for confounders. Additionally, Cox analysis suggested an independent association (Pchildren compared with controls, which may be independently associated with the anthropometrics and perinatal outcomes in addition to the ART procedure. © 2014 S.

    Learning to play musical instruments such as piano was previously shown to benefit post-stroke motor rehabilitation. Previous work hypothesised that the mechanism of this rehabilitation is that patients use auditory feedback to correct their movements and therefore show motor learning. We tested this hypothesis by manipulating the auditory feedback timing in a way that should disrupt such error-based learning. We contrasted a patient group undergoing music-supported therapy on a piano that emits sounds immediately (as in previous studies) with a group whose sounds are presented after a jittered delay. The delay was not noticeable to patients. Thirty-four patients in early stroke rehabilitation with moderate motor impairment and no previous musical background learned to play the piano using simple finger exercises and familiar children's songs. Rehabilitation outcome was not impaired in the jitter group relative to the normal group. Conversely, some clinical tests suggests the jitter group outperformed the normal group. Auditory feedback-based motor learning is not the beneficial mechanism of music-supported therapy. Immediate auditory feedback therapy may be suboptimal. Jittered delay may increase efficacy of the proposed therapy and allow patients to fully benefit from motivational factors of music training. Our study shows a novel way to test hypotheses concerning music training in a single-blinded way, which is an important improvement over existing unblinded tests of music interventions.

    The objectives of this randomized, single-blinded, placebo-controlled pilot trial were to investigate the effects of varenicline on opioid withdrawal among chronic pain patients undergoing opioid detoxification in an interdisciplinary pain program and the feasibility of varenicline use in this population. Twenty-one patients were recruited (varenicline=10, placebo=11), and 7 patients in the varenicline and 11 in the placebo group completed the study. Opioid withdrawal was quantified using the Clinical Opiate Withdrawal Scale, and varenicline-related adverse effects were assessed. Opioid withdrawal scores tended to decrease over the course of opioid tapering in those receiving varenicline and increase in those receiving placebo. Varenicline was well-tolerated in this population, with no adverse drug effects (including nausea) observed and no effect on improvements in pain severity and depression. This randomized pilot study provides preliminary data for future trials of varenicline in opioid-dependent adults with chronic pain undergoing medically directed opioid detoxification.

    Background. Andes virus (ANDV)–related hantavirus cardiopulmonary syndrome (HCPS) has a 35% case fatality rate in Chile and no specific treatment. In an immunomodulatory approach, we evaluated the efficacy of intravenous methylprednisolone for HCPS treatment, through a parallel-group, placebo-controlled clinical trial. Methods. Patients aged >2 years, with confirmed or suspected HCPS in cardiopulmonary stage, admitted to any of 13 study sites in Chile, were randomized by study center in blocks of 4 with a 1:1 allocation and assigned through sequentially numbered envelopes to receive placebo or methylprednisolone 16 mg/kg/day (≤1000 mg) for 3 days. All personnel remained blinded except the local pharmacist. Infection was confirmed by immunoglobulin M antibodies or ANDV RNA in blood. The composite primary endpoint was death, partial pressure of arterial oxygen/fraction of inspired oxygen ratio ≤55, cardiac index ≤2.2, or ventricular tachycardia or fibrillation within 28 days. Safety endpoints included the number of serious adverse events (SAEs) and quantification of viral RNA in blood. Analysis was by intention to treat. Results. Infection was confirmed in 60 of 66 (91%) enrollees. Fifteen of 30 placebo-treated patients and 11 of 30 methylprednisolone-treated patients progressed to the primary endpoint (P = .43). We observed no significant difference in mortality between treatment groups (P = .41). There was a trend toward more severe disease in placebo recipients at entry. More subjects in the placebo group experienced SAEs (P = .02). There were no SAEs clearly related to methylprednisolone administration, and methylprednisolone did not increase viral load. Conclusions. Although methylprednisolone appears to be safe, it did not provide significant clinical benefit to patients. Our results do not support the use of methylprednisolone for HCPS.

    The term "diabetic kidney" has recently been proposed to encompass the various lesions, involving all kidney structures that characterize protean kidney damage in patients with diabetes. While glomerular diseases may follow the stepwise progression that was described several decades ago, the tenet that proteinuria identifies diabetic nephropathy is disputed today and should be limited to glomerular lesions. Improvements in glycemic control may have contributed to a decrease in the prevalence of glomerular lesions, initially described as hallmarks of diabetic nephropathy, and revealed other types of renal damage, mainly related to vasculature and interstitium, and these types usually present with little or no proteinuria. Whilst glomerular damage is the hallmark of microvascular lesions, ischemic nephropathies, renal infarction, and cholesterol emboli syndrome are the result of macrovascular involvement, and the presence of underlying renal damage sets the stage for acute infections and drug-induced kidney injuries. Impairment of the phagocytic response can cause severe and unusual forms of acute and chronic pyelonephritis. It is thus concluded that screening for albuminuria, which is useful for detecting "glomerular diabetic nephropathy", does not identify all potential nephropathies in diabetes patients. As diabetes is a risk factor for all forms of kidney disease, diagnosis in diabetic patients should include the same combination of biochemical, clinical, and imaging tests as employed in non-diabetic subjects, but with the specific consideration that chronic kidney disease (CKD) may develop more rapidly and severely in diabetic patients.

    Full Text Available Purpose: To determine the prevalence, outcome and prognostic factors in children with hemolytic uremic syndrome (HUS who underwent laparotomy. Materials and Methods: The medical records of 104 patients with HUS who presented to our center between 1986 and 2003 were reviewed retrospectively. Data were analyzed using Student′s t test for comparing means, Fisher′s exact test for frequencies and Pearson′s correlation for finding the correlations. Results: 78% of cases presented with vomiting and diarrhea. Seven out of 104 needed surgical exploration. The indications of surgery were acute abdomen, severe abdominal distention and the sign of peritonitis. The findings at laparotomy were intussusceptions, perforation (colon, ileum, gangrene of entire colon, rectosigmoidal tearing, duodenal obstruction and toxic megacolon. Pathological findings were transmural infarction in two cases in which staged surgical management was performed (cecostomy, resection, later anastomosis. Four out of seven patients died because of pulmonary failure, coma and multiple organ failure ( P< 0.05 compared to those who did not need laparotomy. The patients requiring surgery were young (< 3 years, had high leukocyte count (>20000 mm 3 and low albumin level (< 3g/dl ( P< 0.05. Conclusion: Surgical complications of HUS are rare but are assorted with high mortality due to respiratory failure and multiple organ failure. Early decision of laparotomy associated with intensive care, including mechanical ventilation, adequate dialysis and ultrafiltration, are recommended.

    2015-01-01

    Full Text Available Both in vitro and in vivo experiments have confirmed that platelet-rich plasma has therapeutic effects on many neuropathies, but its effects on carpal tunnel syndrome remain poorly understood. We aimed to investigate whether single injection of platelet-rich plasma can improve the clinical symptoms of carpal tunnel syndrome. Fourteen patients presenting with median nerve injury who had suffered from mild carpal tunnel syndrome for over 3 months were included in this study. Under ultrasound guidance, 1-2 mL of platelet-rich plasma was injected into the region around the median nerve at the proximal edge of the carpal tunnel. At 1 month after single injection of platelet-rich plasma, Visual Analogue Scale results showed that pain almost disappeared in eight patients and it was obviously alleviated in three patients. Simultaneously, the disabilities of the arm, shoulder and hand questionnaire showed that upper limb function was obviously improved. In addition, no ultrasonographic manifestation of the carpal tunnel syndrome was found in five patients during ultrasonographic measurement of the width of the median nerve. During 3-month follow-up, the pain was not greatly alleviated in three patients. These findings show very encouraging mid-term outcomes regarding use of platelet-rich plasma for the treatment of carpal tunnel syndrome.

    Turner syndrome is a developmental disorder caused by partial or complete monosomy for the X chromosome in 1 in 2,500 females. We hypothesized that single-nucleotide polymorphism (SNP) array genotyping could provide superior resolution in comparison to metaphase karyotype analysis to facilitate genotype-phenotype correlations. We genotyped 187 Turner syndrome patients with 733,000 SNP marker arrays. All cases met diagnostic criteria for Turner syndrome based on karyotypes (60%) or characteristic physical features. The SNP array results confirmed the diagnosis of Turner syndrome in 100% of cases. We identified a single X chromosome (45,X) in 113 cases. In 58 additional cases (31%), other mosaic cell lines were present, including isochromosomes (16%), rings (5%), and Xp deletions (8%). The remaining cases were mosaic for monosomy X and normal male or female cell lines. Array-based models of X chromosome structure were compatible with karyotypes in 104 of 116 comparable cases (90%). We found that the SNP array data did not detect X-autosome translocations (three cases) but did identify two derivative Y chromosomes and 13 large copy-number variants that were not detected by karyotyping. Our study is the first systematic comparison between the two methods and supports the utility of SNP array genotyping to address clinical and research questions in Turner syndrome.

    The aim of the present study was to evaluate the role of intravenous dexamethasone in relieving the symptoms and signs of vestibular neuritis in the emergency department setting. This was a randomized, placebo-controlled, superiority, single-blind study. Patients were randomized either to intravenous dexamethasone (group A) or to placebo (group B), with all patients receiving symptomatic therapy. The primary outcome was defined as necessity to hospitalize patients who present with vestibular neuritis in the emergency department. The secondary outcomes were (a) improvement in nystagmus, (b) improvement in postural instability, (c) lessening of nausea, (d) lessening of vomiting, and (e) recovery of subjective symptoms. Altogether, 100 patients were randomized, 51 into group A and 49 into group B. There was no difference in the hospitalization rate between groups (P=0.284). In both groups, there was a statistically significant difference in the values of all measured variables 2 h after therapy intervention compared with the baseline values. In group A, significantly fewer patients had third-degree nystagmus 2 h after therapy intervention whereas the difference in group B did not reach statistical significance. After therapy, more patients had first-degree nystagmus in group A as well as in group B than before the intervention. There was a significantly greater absolute difference in European Evaluation of Vertigo scale results in group A compared with group B. The value of dexamethasone cannot be established, given the small sample and limitations of the present study. Some observations consistent with clinical improvement cannot exclude a true treatment effect, and further study is still warranted.

This study evaluated the effectiveness of a telephone-delivered psychoeducational intervention for family caregivers of PWD in alleviating caregiver burden and enhancing caregiving self-efficacy. Subjects and methods: In a single-blinded randomized controlled trial, 38 family caregivers of PWD were randomly allocated into an intervention group or a control group. The intervention group received psychoeducation from a registered social worker over the phone for 12 sessions. Caregivers in the control group were given a DVD containing educational information about dementia caregiving. Outcomes of the intervention were measured by the Chinese versions of the Zarit Burden Interview and the Revised Scale for Caregiving Self-efficacy. Mann–Whitney U tests were used to compare the differences between the intervention and control groups. Results: The level of burden of caregivers in the intervention group reduced significantly compared with caregivers in the control group. Caregivers in the intervention group also reported significantly more gain in self-efficacy in obtaining respite than the control group. Conclusion: A structured telephone intervention can benefit dementia caregivers in terms of self-efficacy and caregiving burden. The limitations of the research and recommendations for intervention are discussed. Keywords: telephone intervention, psychoeducation, dementia caregivers

    Purpose To examine the effects of radial extracorporeal shockwave therapy (rESWT) on plantarflexor spasticity after stroke. Method Twelve patients with stroke were randomly included for this prospective, single-blind clinical trial. Patients received one rESWT session (0.340 mJ/mm 2 , 2000 shots) on plantarflexor muscle. The Modified Modified Ashworth Scale (MMAS), H-reflex tests, ankle range of motion (ROM), passive plantarflexor torque (PPFT) and timed up and go test (TUG) were measured at baseline (T 0 ), immediately after treatment (T 1 ) and one hour after the end of the treatment (T 2 ). Results Patients had improved the MMAS scores for both the gastrocnemius and the soleus muscles, active and passive ROM, PPFT and TUG over time after rESWT. For the PPFT, it was greater at high velocity than at low velocity, and there was a significant three-way interaction between time, knee position (extended/flexed) and velocity (low/high). The H-reflex latency had decreased at T 1 , but there was no significant effect on H max /M max ratio. Conclusions The rESWT improved plantarflexor spasticity, and the effects sustained for one hour, whereas it was not effective in improving spinal excitability. Implications for Rehabilitation One session radial extracorporeal shock wave therapy (rESWT) is safe and effective in improving post stroke plantarflexor spasticity, ankle active and passive range of motion, passive torque, and walking capability. The spasticity scores improved for both the gastrocnemius and the soleus muscles and persisted one hour after rESWT. The magnitude of resistive plantarflexor passive torque in the knee extended position and high velocity was larger over time suggesting greater gastrocnemius spasticity than soleus. The rESWT had no significant effects on alpha motorneuron excitability.

    Open haemorrhoidectomy has been associated with considerable postoperative pain and discomfort. Perianal intradermal injection of methylene blue has been shown to ablate perianal nerve endings and may bring about temporary pain relief after haemorrhoidectomy. We hypothesized that the administration of intradermal methylene blue would reduce postoperative pain during the initial period after surgery. A randomized, prospective, single-blind placebo-controlled trial was conducted. Patients were randomized to intradermal injection at haemorrhoidectomy of either 4 ml 1% methylene blue and 16 ml 0.5% marcaine or of 16 ml 0.5% marcaine and 4 ml saline prior to surgical dissection. Patients were asked to fill in a pain diary with a visual analogue scale. The primary outcome measure was pain score and analgesic use. Secondary outcomes were complications. There were 37 patients in the methylene blue arm and 30 patients in the placebo arm. There were no statistically significant differences in the sex, type of haemorrhoid, number of haemorrhoids excised, duration of surgery or hospital stay. The mean pain scores were significantly lower and the use of paracetamol was also significantly less in the methylene blue group during the first three postoperative days. The risk ratio of acute urinary retention occurring when methylene blue was not used was 2.320 (95% CI 1.754-3.067). Other complication rates were not significantly different. Perianal intradermal injection of methylene blue was useful in reducing the initial postoperative pain of open haemorrhoidectomy.

    Treatment of canine epilepsy is problematic. Few antiepileptic drugs have proven efficacy in dogs and undesirable adverse effects and pharmacoresistance are not uncommon. Consequently, the need for investigation of alternative treatment options is ongoing. The objective of this study was to investigate the efficacy and tolerability of levetiracetam as mono-therapy in dogs with idiopathic epilepsy. The study used a prospective single-blinded parallel group design. Twelve client-owned dogs were included and were randomised to treatment with levetiracetam (30 mg/kg/day or 60 mg/kg/day divided into three daily dosages) or phenobarbital (4 mg/kg/day divided twice daily). Control visits were at days 30, 60 and then every 3 months for up to 1 year. Two or more seizures within 3 months led to an increase in drug dosage (levetiracetam: 10 mg/kg/day, phenobarbital: 1 mg/kg/day). Five of six levetiracetam treated dogs and one of six phenobarbital treated dogs withdrew from the study within 2-5 months due to insufficient seizure control. In the levetiracetam treated dogs there was no significant difference in the monthly number of seizures before and after treatment, whereas in the phenobarbital treated dogs there were significantly (P = 0.013) fewer seizures after treatment. Five phenobarbital treated dogs were classified as true responders (≥50% reduction in seizures/month) whereas none of the levetiracetam treated dogs fulfilled this criterion. Adverse effects were reported in both groups but were more frequent in the phenobarbital group. In this study levetiracetam was well tolerated but was not effective at the given doses as mono-therapy in dogs with idiopathic epilepsy. Copyright © 2015 Elsevier Ltd. All rights reserved.

  20. Unified blind method for multi-image super-resolution and single/multi-image blur deconvolution.

    This paper presents, for the first time, a unified blind method for multi-image super-resolution (MISR or SR), single-image blur deconvolution (SIBD), and multi-image blur deconvolution (MIBD) of low-resolution (LR) images degraded by linear space-invariant (LSI) blur, aliasing, and additive white Gaussian noise (AWGN). The proposed approach is based on alternating minimization (AM) of a new cost function with respect to the unknown high-resolution (HR) image and blurs. The regularization term for the HR image is based upon the Huber-Markov random field (HMRF) model, which is a type of variational integral that exploits the piecewise smooth nature of the HR image. The blur estimation process is supported by an edge-emphasizing smoothing operation, which improves the quality of blur estimates by enhancing strong soft edges toward step edges, while filtering out weak structures. The parameters are updated gradually so that the number of salient edges used for blur estimation increases at each iteration. For better performance, the blur estimation is done in the filter domain rather than the pixel domain, i.e., using the gradients of the LR and HR images. The regularization term for the blur is Gaussian (L2 norm), which allows for fast noniterative optimization in the frequency domain. We accelerate the processing time of SR reconstruction by separating the upsampling and registration processes from the optimization procedure. Simulation results on both synthetic and real-life images (from a novel computational imager) confirm the robustness and effectiveness of the proposed method.

    Recent studies aimed to evaluate the potential effects of perceptive rehabilitation in Parkinson Disease reporting promising preliminary results for postural balance and pain symptoms. To date, no randomized controlled trial was carried out to compare the effects of perceptive rehabilitation and conventional treatment in patients with Parkinson Disease. To evaluate whether a perceptive rehabilitation treatment could be more effective than a conventional physical therapy program in improving postural control and gait pattern in patients with Parkinson Disease. Single blind, randomized controlled trial. Department of Physical and Rehabilitation Medicine of a University Hospital. Twenty outpatients affected by idiopathic Parkinson Disease at Hoehn and Yahr stage ≤3. Recruited patients were divided into two groups: the first one underwent individual treatment with Surfaces for Perceptive Rehabilitation (Su-Per), consisting of rigid wood surfaces supporting deformable latex cones of various dimensions, and the second one received conventional group physical therapy treatment. Each patient underwent a training program consisting of ten, 45-minute sessions, three days a week for 4 consecutive weeks. Each subject was evaluated before treatment, immediately after treatment and at one month of follow-up, by an optoelectronic stereophotogrammetric system for gait and posture analysis, and by a computerized platform for stabilometric assessment. Kyphosis angle decreased after ten sessions of perceptive rehabilitation, thus showing a substantial difference with respect to the control group. No significant differences were found as for gait parameters (cadence, gait speed and stride length) within Su-Per group and between groups. Parameters of static and dynamic evaluation on stabilometric platform failed to demonstrate any statistically relevant difference both within-groups and between-groups. Perceptive training may help patients affected by Parkinson Disease into restoring

    To study the effect of calf stretching box usage in increasing the compliance of performing calf stretching exercise as compared to the conventional exercise method. To study the effect of calf stretching box usage in decreasing the calf muscle tightness and complications as compared to the conventional exercise method. Eighty patients older than 45 years old with calf muscles tightness were enrolled in a prospective, randomized single-blinded controlled trial at the out-patient Rehabilitation medicine clinic, Siriraj Hospital, Bangkok Thailand between April and August 2009. Patients were randomized into two groups, the study group (stretching by using calf stretching box) and the control group (stretching by the conventional exercise method). Patients in both groups were asked to hold the stretch for at least 1 minute and to perform the stretching program at least two times per day, every day for two weeks. Furthermore, they were asked to record the real frequency and duration of their exercise and complications in a logbook every day. Thirty-eight patients in each group completed the study. The baseline characteristics of the patients in both groups were similar. The study group had higher frequency and longer duration of performing calf stretching exercise than the control group. They also reported more decrease of calf muscle tightness with less pain complication (shoulder pain, knee pain, low back pain, and calf muscle pain) than the control group (p calf muscle and degree of ankle range of motion between the two groups. Stretching calf muscle with calf stretching box can increase compliance, decrease calf muscle tightness and decrease complications when compared with the conventional exercise method.

    Hyperphagia increases eating-associated risks for people with dementia and distress for caregivers. The purpose of this study was to compare the long-term effectiveness of spaced retrieval (SR) training and SR training combined with Montessori activities (SR + M) for improving hyperphagic behaviors of special care unit residents with dementia. The study enrolled patients with dementia suffering from hyperphagia resident in eight institutions and used a cluster-randomized single-blind design, with 46 participants in the SR group, 49 in the SR + M group, and 45 participants in the control group. For these three groups, trained research assistants collected baseline data on hyperphagic behavior, pica, changes in eating habits, short meal frequency, and distress to caregivers. The SR and SR + M groups underwent memory training over a 6-week training period (30 sessions), and a generalized estimating equation was used to compare data of all the three groups of subjects obtained immediately after the training period and at follow-ups 1 month, 3 months, and 6 months later. Results showed that the hyperphagic and pica behaviors of both the SR and SR + M groups were significantly improved (P<0.001) and that the effect lasted for 3 months after training. The improvement of fast eating was significantly superior in the SR + M group than in the SR group. The improvement in distress to caregivers in both intervention groups lasted only until the posttest. Improvement in changes in eating habits of the two groups was not significantly different from that of the control group. SR and SR + M training programs can improve hyperphagic behavior of patients with dementia. The SR + M training program is particularly beneficial for the improvement of rapid eating. Caregivers can choose a suitable memory training program according to the eating problems of their residents.

    Full Text Available ABSTRACT Objectives: To compare the response to tiocolchicine and verapamil injection in the plaque of patients with Peyronie's disease. Materials and Methods: Prospective, single-blind, randomized study, selecting patients who have presented Peyronie's disease for less than 18 months. Thiocolchicine 4mg or verapamil 5mg were given in 7 injections (once a week. Patients who had received any treatment for Peyronie's disease in the past three months were excluded. The parameters used were the International Index of Erectile Function (IIEF-5 score, analysis of the curvature on pharmaco-induced erections and size of the plaque by ultrasonography. Results: Twenty-five patients were randomized, 13 received thiocolchicine and 12 were treated with verapamil. Both groups were statistically similar. The mean curvature was 46.7° and 36.2° before and after thiocolchicine, respectively (p=0.019 and 50.4° and 42.08° before and after verapamil, respectively (p=0.012. The curvature improved in 69% of patients treated with thiocolchicine and in 66% of those who received verapamil. Regarding sexual function, there was an increase in the IIEF-5 from 16.69 to 20.85 (p=0.23 in the thiocolchicine group. In the verapamil group the IIEF-5 score dropped from 17.50 to 16.25 (p=0.58. In the thiocolchicine group, the plaque was reduced in 61% of patients. In the verapamil group, 8% presented decreased plaque size. No adverse event was associated to thiocolchicine. Conclusion: The use of thiocolchicine in Peyronie's disease demonstrated improvement on penile curvature and reduction in plaque size. Thiocolchicine presented similar results to verapamil in curvature assessment. No significant side effects were observed with the use of tiocolchicine.

    This randomized single-blinded crossover study aimed to investigate whether bilateral sacral nerve stimulation (SNS) is more efficient than unilateral stimulation for faecal incontinence (FI). Patients with FI who responded during a unilateral test stimulation, with a minimum improvement of 50% were eligible. Twenty-seven patients who were accepted to enter the trial were bilaterally implanted with two permanent leads and pacemakers. Patients were randomized into three periods of 4 weeks' stimulation including unilateral right, unilateral left and bilateral stimulation. Symptoms scores and bowel habit diaries were collected at baseline and in each study period. A 1-week washout was introduced between each study period. Twenty-seven (25 female) patients with a median age of 63 (36-84) years were bilaterally implanted from May 2009 to June 2012. The median number of episodes of FI per 3 weeks significantly decreased from 17 (3-54) at baseline to 2 (0-20) during stimulation on the right side, 2 (0-42) during stimulation on the left side and 1 (0-25) during bilateral stimulation. The Wexner incontinence score improved significantly from a median of 16 (10-20) at baseline to 9 (0-14) with right-side stimulation, 10 (0-15) with left-side stimulation and 9 (0-14) with bilateral stimulation. The differences between unilateral right or unilateral left and bilateral stimulation were non-significant, for FI episodes (P = 0.3) or for Wexner incontinence score (P = 0.9). Bilateral SNS therapy for FI is not superior to standard unilateral stimulation in the short term. Equal functional results can be obtained regardless of the side of implantation.

    Nowadays, pain and disability due to chronic knee arthritis is a very common problem in middle aged people. A lot of modalities for management are available, including conservative analgesics and up to surgical interventions. Radiofrequency ablation of genicular nerves is assumed to be an effective less invasive and safe pain alleviation modality. To evaluate the efficacy of fluoroscopic guided radiofrequency neurotomy of the genicular nerves for alleviation of chronic pain and improvement of function in patients with knee osteoarthritis. A single-blind randomized controlled trial. Pain management unit, and Rheumatology and Rehabilitation clinics of Assiut University hospitals, Assiut, Egypt. This study involved 60 patients with chronic knee osteoarthritis. Radiofrequency neurotomy of the genicular nerves was done for 30 patients (Group A) while the other 30 patients (Group C) received conventional analgesics only. The outcome measures included visual analog scale (VAS), Western Ontario and McMaster Universities Index (WOMAC), and Likert scale for patient satisfaction in the 2nd week,3rd, and 6th months. There were significant differences regarding the VAS in the 2nd week, 3rd, and 6th months between the 2 groups, and a significant difference in total WOMAC index in the 6th month only. There were significant changes when comparing pretreatment values with the values during the whole follow-up period with regard to the VAS and total WOMAC index in both groups. No diagnostic block was done prior to radiofrequency. We recommend the use of such a technique on a larger number of OA patients, with a longer follow-up period. RF can ameliorate pain and disability in chronic knee osteoarthritis in a safe and effective manner. Chronic pain, radiofrequency (RF), knee osteoarthritis.

    Full Text Available Aims: To examine the pattern and extent of cardiovascular developmental alterations among children conceived by assisted reproductive technology (ART and its association with potential confounders. Methods: The present study was a prospective single-blind pilot design lasting 15 months. The ART group was recruited by a non-random, consecutive sample on the basis of the unique personal identification number assigned to ART children, whereas spontaneous conception controls were recruited by a population-based random sample from the same hospital by age. Echocardiography was available for the measurement of 128 ART children and 100 controls with respect to cardiovascular geometric morphology and cardiac function. Results: The majority of cardiac geometric morphology parameters were comparable among the study groups (P>0.05, except for significant increases in left ventricular (LV relative wall thickness (P=0.038, LV mass index (P=0.005 and LV remodeling index (P=0.005 in ART children after adjustment for age, gender, body surface area and heart rate. The results showed similarity in LV systolic function characterized by ejection fraction (P=0.140 and shortening fraction (P=0.167 between the groups. However, ART children had a significant tendency toward a decrease in mitral A (P=0.008 and mitral E′ (P=0.012 compared with controls after adjusting for confounders. Additionally, Cox analysis suggested an independent association (PConclusion: Our findings support the presence of remodeling in the left cardiac geometric morphology and diastolic dysfunction and the absence of any change to the aortocoronary morphometry or systolic function in ART children compared with controls, which may be independently associated with the anthropometrics and perinatal outcomes in addition to the ART procedure.

    Gait and balance dysfunction are major symptoms in Parkinson's disease (PD). Treadmill training improves gait characteristics in this population but does not reflect the dynamic nature of controlling balance during ambulation in everyday life contexts. To evaluate whether postural perturbations during treadmill walking lead to superior effects on gait and balance performance compared with standard treadmill training. In this single-blind randomized controlled trial, 43 PD patients (Hoehn & Yahr stage 1-3.5) were assigned to either an 8-week perturbed treadmill intervention (n = 21) or a control group (n = 22) training on the identical treadmill without perturbations. Patients were assessed at baseline, postintervention, and at 3 months' follow-up. Primary endpoints were overground gait speed and balance (Mini-BESTest). Secondary outcomes included fast gait speed, walking capacity (2-Minute Walk Test), dynamic balance (Timed Up-and-Go), static balance (postural sway), and balance confidence (Activities-Specific Balance Confidence [ABC] scale). There were no significant between-group differences in change over time for the primary outcomes. At postintervention, both groups demonstrated similar improvements in overground gait speed ( P = .009), and no changes in the Mini-BESTest ( P = .641). A significant group-by-time interaction ( P = .048) existed for the Timed Up-and-Go, with improved performance only in the perturbation group. In addition, the perturbation but not the control group significantly increased walking capacity ( P = .038). Intervention effects were not sustained at follow-up. Our primary findings suggest no superior effect of perturbation training on gait and balance in PD patients. However, some favorable trends existed for secondary gait and dynamic balance parameters, which should be investigated in future trials.

    Research into surfactant solutions for the debridement of chronic wounds suggests that surfactants may support wound bed preparation (WBP) in chronic wounds, however their efficacy has not been evaluated in randomised controlled trials (RCTs). Our aim was to assess the clinical efficacy of a propylbetaine-polihexanide (PP) solution versus normal saline (NS) solution in WBP, assessing inflammatory signs and wound size reduction in patients with pressure ulcers (PUs) or vascular leg ulcers. In a single-blinded randomised controlled trial (RCT) patients were randomly allocated to two groups and treated with either propylbetaine-polihexanide (PP) solution (Prontosan) or NS. Wounds were assessed using the Bates-Jensen wound assessment tool (BWAT). Assessments took place at inclusion (T0), day 7 (T1), day 14 (T2), day 21 (T3), and day 28 (T4). Outcomes were analysed using a two-tailed Student's t-test. A total of 289 patients were included. Both groups had similar demographics, clinical status, and wound characteristics. Data analysis showed statistically significant differences between T0 and T4 for the following outcomes: BWAT total score, p=0.0248; BWAT score for inflammatory items, p=0.03; BWAT scores for wound size reduction (p=0.049) and granulation tissue improvement (p=0.043), all in favour of PP. The assessment of pain did not show any significant difference between the two groups. The study results showed significantly higher efficacy of the PP solution versus NS solution, in reducing inflammatory signs and accelerating the healing of vascular leg ulcers and PUs. This evidence supports the update of protocols for the care of chronic wounds. The authors have no conflict of interest regarding this research. This is an investigator initiated trial. B. Braun Milano SpA kindly provided the material under investigation for both treatment groups, and paid the Ethics Committees' application fees in all participating centres.

    Topical corticosteroid or corticosteroid/calcipotriol preparations are recommended first-line topical treatments of psoriasis, but a main cause for the lack of efficacy of topical treatments is considered low rates of adherence to topical drugs. Patient support by the use of applications (apps) for smartphones is suggested to improve medical adherence. Design: An investigator-initiated, single-center, single-blind, parallel-group, phase-4 clinical superiority randomized controlled trial (RCT). 134 patients 18 to 75 years of age with mild-to-moderate psoriasis, who are capable of reading English language, own a smartphone, and are candidates for the study drug calcipotriol and betamethasone dipropionate (Cal/BD) cutaneous foam once daily prn (pro re nata). A 28-day adherence-supporting app providing compulsory daily treatment reminders that pop-up on the smartphone screen with a short alert sound. The app synchronizes through Bluetooth® to an electronic monitor (EM) attached to the medication canister. The EM contains a chip registering the amount of foam, day and time the patient use the foam dispenser. The information is displayed in a diary that shows the amount of Cal/BD cutaneous foam used and the number of applied treatment sessions. The app has an optional diary with the patient's rating of symptoms. Non-intervention: Use of Cal/BD cutaneous foam and EM without the app. All participants are prescribed Cal/BD cutaneous foam prn for the entire study period. Primary outcome obtained in week 4: rates of adherence measured by patient report, weight of medication canisters, and number of treatment sessions measured by the EM. Secondary outcomes obtained at baseline, weeks 4, 8, and 26: Lattice System Physician's Global Assessment (LS-PGA) and Dermatology Quality of Life Index (DLQI). This trial tests of whether an app can improve rates of adherence to a topical antipsoriatic drug. If the app improves rates of adherence and reduces the burden of psoriasis in a

We evaluated the effects of Lactobacillus brevis KB290 (KB290, which has been demonstrated to be effective at improving bowel movements and the composition of intestinal microflora, on IBS symptoms. Methods We performed a placebo control double-blind cross matched trial. Thirty-five males and females (aged 6 years and above who had been diagnosed with IBS according to the Rome III criteria were divided into 2 groups, and after a 4-week pre-trial observation period, they were administered test capsules containing KB290 or placebo for 4 weeks (consumption period I. Then, the capsule administration was suspended for 4 weeks in both groups (washout period, before the opposite capsules were administered for a further 4 weeks (consumption period II. Fecal samples were collected on the first day of the pre-consumption observation period, the last day of consumption period I, the last day of the washout period, and the last day of consumption period II. In addition, the subjects’ IBS symptoms and quality of life (QOL and any adverse events that they experienced were evaluated. Results No significant difference in IBS symptoms was noted among the various periods. However, the mean QOL scores were improved during the test capsule consumption. The frequencies of watery and mushy feces were significantly lower in the test capsule consumption period than during the pre-consumption observation period, and the frequency of abdominal pain was significantly reduced in the test capsule consumption period compared with the other periods. The frequency of the genus Bifidobacterium was significantly higher, and that of the genus Clostridium was significantly lower, after the test capsule consumption than after the placebo consumption. The frequencies of the genera Lactobacillus, Bacteroides, and Enterococcus were also

    Although eosinophilia-myalgia syndrome has been linked to use of tryptophan, it has been unclear whether tryptophan itself or a contaminant causes illness. In Oregon, we compared the brand and source of tryptophan used by 58 patients with eosinophilia-myalgia syndrome with the brand and source of tryptophan used by 30 asymptomatic controls identified through a random telephone survey and 63 asymptomatic controls who contacted the Oregon Health Division voluntarily. Although a single brand/retail lot of tryptophan was statistically associated with the development of eosinophilia-myalgia syndrome, there was no common importer, wholesaler, tablet maker, encapsulator, or distributor. However, 45 (98%) of 46 cases had taken a product made by one manufacturer, compared with three (30%) of 10 telephone survey controls and 15 (48%) of 31 volunteer controls. Retail lots of tryptophan from this manufacturer that were associated with cases were significantly more likely to have been produced from January through June 1989 than lots from this manufacturer that were taken by controls. These findings indicate that the recent epidemic of eosinophilia-myalgia syndrome was caused by a contaminant or an alteration in a subset of tryptophan manufactured by a single company in Japan shortly before the outbreak began.

    Some peer reviewers may inappropriately, or coercively request that authors include references to the reviewers' own work. The objective of this study was to evaluate whether, compared to reviews for a journal with single-blind peer review, reviews for a journal with open peer review included (1) fewer self-citations; (2) a lower proportion of self-citations without a rationale; and (3) a lower ratio of proportions of citations without a rationale in self-citations versus citations to others' work. Peer reviews for published manuscripts submitted in 2012 to a single-blind peer review journal, the Journal of Psychosomatic Research, were previously evaluated (Thombs et al., 2015). These were compared to publically available peer reviews of manuscripts published in 2012 in an open review journal, BMC Psychiatry. Two investigators independently extracted data for both journals. There were no significant differences between journals in the proportion of all reviewer citations that were self-citations (Journal of Psychosomatic Research: 71/225, 32%; BMC Psychiatry: 90/315, 29%; p=.50), or in the proportion of self-citations without a rationale (Journal of Psychosomatic Research: 15/71, 21%; BMC Psychiatry: 12/90, 13%; p=.21). There was no significant difference between journals in the proportion of self-citations versus citations to others' work without a rationale (p=.31). Blind and open peer review methodologies have distinct advantages and disadvantages. The present study found that, in reasonably similar journals that use single-blind and open review, there were no substantive differences in the pattern of peer reviewer self-citations.

    Moderate consumption of beer is associated with lower cardiovascular (CV) risk. The goal of this study was to determine the effect of beer consumption on CV risk. To explore the underlying mechanisms, we studied the acute effects of the constituents of beer (alcohol and antioxidants), on established predictors of CV risk: endothelial function, aortic stiffness, pressure wave reflections and aortic pressure. In a randomized, single-blind, crossover study, 17 healthy, non-smoking, men (ages 28.5 ± 5.2 y with body mass index 24.4 ± 2.5 kg/m(2)) consumed on three separate occasions, at least 1 wk apart: 1. 400 mL of beer and 400 mL water, 2. 800 mL of dealcoholized beer (same amount of polyphenols as in the 400 mL of beer), and 3. 67 mL of vodka and 733 mL water (same amount of alcohol as in the 400 mL of beer). Each time aortic stiffness (pulse wave velocity), pressure wave reflections (AΙx), aortic and brachial pressure (Sphygmocor device), and endothelial function (brachial flow mediated dilatation) were assessed at fast and 1 and 2 h postprandial. Aortic stiffness was significantly and similarly reduced by all three interventions. However, endothelial function was significantly improved only after beer consumption (average 1.33%, 95% confidence interval [CI] 0.15-2.53). Although wave reflections were significantly reduced by all three interventions (average of beer: 9.1%, dealcoholized beer: 2.8%, vodka 8.5%, all CI within limits of significance), the reduction was higher after beer consumption compared with dealcoholized beer (P = 0.018). Pulse pressure amplification (i.e., brachial/aortic) was increased by all three test drinks. Beer acutely improves parameters of arterial function and structure, in healthy non-smokers. This benefit seems to be mediated by the additive or synergistic effects of alcohol and antioxidants and merits further investigation. Copyright © 2013 Elsevier Inc. All rights reserved.

    Pityriasis versicolor (PV) is a common superficial fungal infection of skin caused by the fungus, Malassezia furfur. It can occur at any age but occurs mainly during adolescence and typically presents with hypopigmented or hyperpigmented scaling plaques, generally on the trunk and upper arms. It often poses a therapeutic challenge. In the Unani system of medicine, many herbal drugs are used empirically for its treatment. The objective of this study was to evaluate safety and efficacy of a topical Polyherbal Unani formulation in the management of PV on scientific parameters. This was a randomized, single-blind, standard controlled study. This study was performed in the Dermatology Outpatient Department, National Institute of Unani Medicine, Bangalore, India. Forty-six (46) patients with PV were included in the study after taking informed consents and were randomly allocated to test and control groups. In the test group, a polyherbal formulation was advised for topical application while in the control group, sodium thiosulphate lotion (20%) was advised locally for a duration of 1 month. The assessment of the severity of PV and efficacy of treatment in both groups was carried out using the Total Sign and Symptom Score (TSSS) scale. Data were analyzed with the Instat Graph pad. The mean±standard error of the mean (SEM) scores of TSSS in the test group were 7.7±1.174 and 0.9±0.7881 before and after treatment, respectively, while it was 6.9±0.8756 and 1.2±0.7888 in the control group before and after treatment, respectively. Mean±SEM of TSSS of both groups was found to be significantly lowered (p<0.001) after treatment when compared with mean±SEM of TSSS before treatment. However, the polyherbal formulation showed precedence over the standard drug by exhibiting comparatively quicker response. Furthermore, no unpleasant side-effects were observed in the test group during and after the study. This study concluded that polyherbal Unani formulation is safe, effective

In particular, we tested the soothing and anti-itch effect of Quercevita®, 1% cream for external use, a formulation characterized by a phospholipids-based delivery system.Patients and methods: The study was a monocentric, single blind trial that enrolled a group of 30 healthy volunteers. The back of each subject was examined to identify four quadrants with no previous skin damage or naevi that were treated in order to induce a controlled and reversible form of skin stress. The areas were treated as follows: no product; Quercevita® 1% cream, 2 mg/cm2; placebo; positive control (a commercially available topical formulation containing 1% dexchlorpheniramine.Results: Only quercetin phospholipids 1% and dexchlorpheniramine 1% achieved a significant reduction in erythema with comparable results: (–10.05% [P=0.00329] for quercetin phospholipids 1% vs –14.05% [P=0.00046] for the positive control. Moreover, quercetin phospholipids 1% and dexchlorpheniramine 1% were both associated with a significant decrease in mean wheal diameter: (–13.25% and –12.23% for dexchlorpheniramine 1%, respectively. Similar findings were reported for the other tested parameters.Conclusion: Quercetin has a skin protective effect against damage caused by a variety of insults, including UV radiation, histamine, or contact with toxic chemical compounds. Indeed, quercetin is able

The purpose of this study was to compare the long-term effectiveness of spaced retrieval (SR training and SR training combined with Montessori activities (SR + M for improving hyperphagic behaviors of special care unit residents with dementia. Methods: The study enrolled patients with dementia suffering from hyperphagia resident in eight institutions and used a cluster-randomized single-blind design, with 46 participants in the SR group, 49 in the SR + M group, and 45 participants in the control group. For these three groups, trained research assistants collected baseline data on hyperphagic behavior, pica, changes in eating habits, short meal frequency, and distress to caregivers. The SR and SR + M groups underwent memory training over a 6-week training period (30 sessions, and a generalized estimating equation was used to compare data of all the three groups of subjects obtained immediately after the training period and at follow-ups 1 month, 3 months, and 6 months later. Results: Results showed that the hyperphagic and pica behaviors of both the SR and SR + M groups were significantly improved (P<0.001 and that the effect lasted for 3 months after training.

    Childhood-onset idiopathic nephrotic syndrome affects 1.15-3.4 children/100,000 children/year in Western Countries. Immune-mediated mechanisms, particularly T cell-mediated, are thought to play a key pathogenic role. The genetic basis of the disease is still poorly understood. We tested the association between single nucleotide polymorphisms (SNPs) of four genes encoding Fc gamma receptors (FCGR2A, FCGR2B, FCGR3A, FCGR3B) and idiopathic nephrotic syndrome in a case-control study of paediatric patients. Children with idiopathic nephrotic syndrome (aged 1-16 years) were included. FCGR2A rs1801274 and FCGR3A rs396991 SNPs were genotyped using real-time PCR with the TaqMan method, while FCGR2B rs1050501 and FCGR3B NA1/NA2 were genotyped using Sanger sequencing. Fisher's exact test was used to explore genetic association. We enrolled 103 idiopathic nephrotic syndrome patients and 181 healthy controls. A significant association was found between idiopathic nephrotic syndrome and FCGR2A rs1801274 SNP (both with the T allele and the TT genotype, p value=0.0009, OR 1.81, 95% CI 1.27-2.59 and p value=0.0007, OR 2.39, 95% CI 1.44-3.99, respectively). No associations were found for the remaining SNPs. Fc gamma receptors might modulate response to rituximab; since 60 of the enrolled patients were treated with rituximab, we also tested the association between the studied SNPs and rituximab efficacy in this patient subgroup, but found only a weak association with FCGR2A CC genotype (p value=0.03). The FCGR2A rs1801274 SNP in the gene encoding the activating receptor CD32A confers susceptibility to idiopathic nephrotic syndrome. Copyright © 2017 European Federation of Immunological Societies.

    Full Text Available Background. Guillain-Barré Syndrome (GBS is a potentially fatal autoimmune neurological disorder. The severity varies among the four main subtypes, named as Acute Inflammatory Demyelinating Polyneuropathy (AIDP, Acute Motor Axonal Neuropathy (AMAN, Acute Motor Sensory Axonal Neuropathy (AMSAN, and Miller-Fisher Syndrome (MF. A proper subtype identification may help to promptly carry out adequate treatment in patients. Method. We perform experiments with 15 single classifiers in two scenarios: four subtypes’ classification and One versus All (OvA classification. We used a dataset with the 16 relevant features identified in a previous phase. Performance evaluation is made by 10-fold cross validation (10-FCV. Typical classification performance measures are used. A statistical test is conducted in order to identify the top five classifiers for each case. Results. In four GBS subtypes’ classification, half of the classifiers investigated in this study obtained an average accuracy above 0.90. In OvA classification, the two subtypes with the largest number of instances resulted in the best classification results. Conclusions. This study represents a comprehensive effort on creating a predictive model for Guillain-Barré Syndrome subtypes. Also, the analysis performed in this work provides insight about the best single classifiers for each classification case.

    To assess the effectiveness of standardized topical Chamomile (Matricaria chamomilla L.) oil in patients with severe carpal tunnel syndrome, as a complementary treatment. A pilot randomized double-blind placebo-controlled trial was conducted. Twenty six patients with documented severe carpal tunnel syndrome were treated in two parallel groups with a night splint plus topical chamomile oil or placebo. They were instructed to use their prescribed oil for 4 weeks, twice daily. Symptomatic and functional status of the patients and their electrodiagnostic parameters were evaluated when enrolled and after the trial period, as our outcome measures. A significant improvement of symptomatic and functional status of patients in the chamomile oil group was observed (p = 0.019 and 0.016, respectively) compared with those in the placebo group. However, electrodiagnostic parameters showed no significant changes between the two groups. Chamomile oil improved symptomatic and functional status of patients with severe carpal tunnel syndrome.

    Wolfram syndrome is a progressive neurodegenerative disorder also known as DIDMOAD (diabetes insipidus, diabetes mellitus, optic atrophy and deafness). The majority of cases are caused by mutations in the WFS1 gene. WFS1 is located at 4p16.1 and encodes wolframin, a transmembrane endoplasmic reticulum (ER) protein involved in the negative regulation of ER stress signalling. To date, over 120 WFS1 mutations have been described. In this study, we report a consanguineous family with three siblings affected by Wolfram syndrome. A homozygous single base pair deletion (c.877delC, L293fsX303) was found in the WFS1 gene in all three affected siblings.

    Most cases of idiopathic nephrotic syndrome in childhood are responsive to corticosteroids. However, there is a small group of children that demonstrate steroid resistance (steroid-resistant nephrotic syndrome; SRNS), steroid dependence, or that frequently relapse (frequent-relapse steroid-sensitive nephrotic syndrome; FR-SSNS) which are more clinically difficult to treat. Therefore, second-line immunosuppressants, such as alkylating agents, calcineurin inhibitors, antimetabolites and, more recently, rituximab, have been used with varying success. The objective was to evaluate the response rates of various second-line therapies in the treatment of childhood nephrotic syndrome. A retrospective chart review of pediatric subjects with idiopathic nephrotic syndrome was conducted at a single tertiary care center (2007-2012). Drug responses were classified as complete response, partial response, and no response. Of the 188 charts reviewed, 121 children were classified as SSNS and 67 children as SRNS; 58% were classified as FR-SSNS. Sixty-five subjects were diagnosed with focal segmental glomerulosclerosis via biopsy. Follow-up ranged from 6 months to 21 years. The combined rate of complete and partial response for mycophenolate mofetil (MMF) was 65% (33/51) in SSNS and 67% (6/9) in SRNS. For tacrolimus, the response rate was 96% (22/23) for SSNS and 77% (17/22) for SRNS. Eighty-three percent (5/6) of SSNS subjects treated with rituximab went into complete remission; 60% relapsed after B-cell repletion. Eight refractory subjects were treated with combined MMF/tacrolimus/corticosteroid therapy with a 75% response rate. Our experience demonstrates that older medications can be replaced with newer ones such as MMF, tacrolimus, and rituximab with good outcomes and better side effect profiles. The treatment of refractory cases with combination therapy is promising.

    Acupuncture is increasingly used as an alternative to medical therapy for various pain conditions. To study the effect of acupuncture in experimental and clinical studies, a control condition with sham acupuncture is needed. However, as such models have not been established in assessment of acupunctures effect against visceral pain, this study aimed to validate a new method for blinded sham acupuncture in experimental rectal pain. Fifteen subjects underwent a sequence of either sham or real acupuncture in randomized order. In the sham arm, a hollow inner tube with a sharp tip was fitted into an outer tube and subjects were blinded to the stimulations. Before and after the intervention, pain was induced by rectal stimulation with an inflatable balloon distended until the subjects' pain threshold was reached. The resting electroencephalogram (EEG) was quantified by spectral power analysis to explore the central nervous system effects objectively. Additionally, after the second study day, the subject was asked to indicate the sequence of interventions. A significant increase in rectal balloon volume was observed after sham 12 ± 21 mL (P = 0.049) and acupuncture 17 ± 30 mL (P = 0.046). However, the change in volume was not different between groups (P = 0.6). No differences in EEG spectral power distributions between sham and acupuncture were seen (all P > 0.6). The correct sequence of sham and acupuncture was indicated by 36% of the subjects (P = 0.4). The presented sham procedure provides a valid method for blinding of "sham acupuncture" and may be used in future blinded controlled trials of acupuncture for visceral pain. © 2015 World Institute of Pain.

    We aimed to investigate the efficacy of ascorbic acid and acetylsalicylic acid among type II diabetes mellitus patients using metformin (only) for diabetes management therapy. A 12-month single blinded multicenter randomized control trial was designed to investigate the measured variables [Glycated Hemoglobin (HbA1c), Renal function, Albumin Creatinine Ratio (ACR) etc.]. The trial was randomized into 2 experimental parallel arms (ascorbic acid vs acetylsalicylic acid) were blinded with study supplements in combination with metformin and findings were compared to control arm with metformin alone and blinded with placebo. Withdrawal criteria was defined to maintain the equity and balance in the participants in the whole trial. Patients with metformin and ascorbic acid (parallel arm I) was twice more likely to reduce HbA1c than metformin alone (control arm) in a year (OR 2.31 (95% CI 1.87-4.42) p ascorbic acid with metformin is more effective against reducing risks for diabetes related long-term complications (including ACR).

    Iatrogenic Cushing's syndrome is a well-known adverse effect of glucocorticoids. It usually develops after prolonged exposure to excessive amounts of synthetic glucocorticolds. The development of iatrogenic Cushing's syndrome (ICS) after a single and low dose of synthetic glucocorticoid is an exceptional event. Up to now, only a few number of cases have been associated with triamcinolone acetonide and they have always been related to local administration. We report, for the first time, a patient who developed ICS after a single low dose of parenterally (im) administered triamcinolone acetonide. She was a 45-yr-old woman who referred to us because of cushingoid appearance, whose hormonal determinations were suggestive of secondary adrenal insufficiency. Clinical features were developed one month after the administration of a 40 mg single-dose of im triamcinolone acetonide because of acute laryngitis. Endocrinological evaluation confirmed the hypothalamic-pituitary-adrenal (HPA) axis suppression. Eight months later, cushingoid phenotype had completely disappeared and HPA function had spontaneously recovered. We review clinical features and comment on the possible pathogenic mechanisms of this particular and new form of ICS.

    The aim of this study was to determine the long-term results of children followed up with a diagnosis of nephrotic syndrome in a single center. The medical data of 33 patients aged between 6 months and 10 years who were diagnosed with idiopathic nephrotic syndrome in our center between January 2000 and December 2012 and followed up for a period of 2-12 years were reviewed (Gulhane Military Medical Academy Ethics committee, 07.11.2012/10). The mean age of disease onset was 3.2±2.04 years (range: 0.5-10 years) and the mean follow-up period was 6±3.4 years (range: 2-12 years). Thirteen (39.4%) of the study group (or the patients) were female and 20 (60.6%) were male. Twenty seven (1.8%) of the patients were sensitive to steroid and 6 (18.1%) were resistant to steroid. Four (12.1%) of the steroid-resistant patients had steroid-dependent nephrotic syndrome, 5 (15.2%) had frequently relapsing nephrotic syndrome and 18 (54.5%) had rarely relapsing nephrotic syndrome. Histopathological diagnoses of six patients who underwent biopsy because of resistance to steroid were as follows: focal segmental glomerulosclerosis (n=3), C1q nephropathy (n=1), diffuse mesangial proliferation (n=1) and membraneous nephropathy (n=1). Fifteen (45.5%) patients entered into full remission and 2 (6%) patients developed chronic renal failure. Treatment complications including decreased bone mineral density in three patients (9%), short stature in 2 patients (6%) and cataract in 2 patients (6%) developed. Children with nephrotic syndrome carry a risk in terms of short stature, osteoporosis, cataract and renal failure in the long-term follow-up. It was observed that our rates of response to steroid were similar to the literature and the most common histopathological diagnosis was focal segmental glomerulosclerosis in our patients who underwent biopsy because of resistance to steroid. It was thought that multi-center studies should be conducted to demonstrate regional or national differences

    Birt-Hogg-Dubé (BHD) syndrome is an autosomal dominant condition characterized by dermatologic lesions, pulmonary manifestations, and renal tumors. The syndrome arises from germline mutations in the folliculin (FLCN) gene. We present findings from the single largest family BHD cohort described to date. Primary objectives were to characterize cystic lung changes on computed tomography (CT) chest scanning and identify features that stratify patients at higher risk of pneumothorax. Secondary objectives entailed description of the following: type and natural history of BHD-associated pneumothorax, pulmonary function characteristics, and relationship between cystic lung changes and pulmonary function. The study was a retrospective chart review for a case series of a single family. Over 70 family members of a proband with documented BHD were identified, 68 of which consented to genetic testing. All those with confirmed BHD were offered a clinical assessment by the Medical Genetics and Pulmonary services which included a history, physical exam, complete pulmonary function tests, and computed tomography (CT) scan of the chest and abdomen. Thirty-six individuals had a heterozygous mutation in the FLCN gene (c.59delT). Of these, 100 % (28/28) had pulmonary cysts, 41 % (13/32) had spontaneous pneumothoraces, 26 % (8/31) had kidney cysts, 3 % (1/31) had renal tumors, and 53 % (18/34) had dermatologic manifestations. Recurrent pneumothoraces were common (40 %). Cyst size (OR 3.23, 95 % CI 1.35-7.73) and extent of lower lung zone disease (OR 6.43, 95 % CI 1.41-29.2) were the only findings associated with pneumothorax. The size or extent of cystic disease did not correlate with lung function results. This is the largest single family cohort of patients with BHD syndrome documented to date. We found that all individuals had pulmonary cysts, pneumothoraces were common, and cyst size and lower lobe predominant disease were associated with pneumothorax. Lung function was generally

    The aim of this study is to investigate the simultaneous effect of pomegranate juice on components of the metabolic syndrome, including high sensitive C-reactive protein (hs-CRP) as an inflammatory index and glycemic and lipid profile indices in patients with metabolic syndrome. In a double- blind 2*2 crossover study, 30 individuals suffering from metabolic syndrome received a daily dose of 500 mL pomegranate juice for a period of one week. After one week of wash out period, they received a placebo for one week. Lipid profile, blood glucose control indices including fasting blood glucose, fasting insulin, homeostatic model assessment of insulin resistance (HOMA-IR), systolic and diastolic blood pressure, and hs-CRP were measured at the beginning and end of the study. To analyze the data, a repeated measure analysis of variance and a t-test were performed. The results indicated that in comparison to the placebo, pomegranate juice was more effective in reducing the systolic and diastolic blood pressure (p = 0.00) and hs-CRP (p = 0.018). The level of triglyceride (p = 0.030) and very low-density lipoproteins cholesterol (VLDL-C) (p = 0.014) were increased after the consumption of pomegranate juice, as opposed to the baseline condition. The rest of lipid profile, fasting blood glucose (FBS), insulin, and HOMA-IR of the participants did not show any significant difference. Natural pomegranate juice supplementation lowered the level of systolic and diastolic blood pressure in patients with metabolic syndrome as well as their blood hs-CRP. However, it also increased their triglyceride and VLDL-C.

    Traditional Chinese medicine (TCM) has a long history in the treatment of psoriasis vulgaris. We aimed to evaluate the clinical efficacy and safety of Chinese herbal Pulian ointment in treating psoriasis vulgaris of blood-heat syndrome. A multicenter, randomized, double-blind, placebo-controlled trial was conducted. Participants with psoriasis vulgaris of blood-heat syndrome were blinded and randomized to receive Pulian ointment or placebo ointment twice daily for 4 weeks, with follow-up 8 weeks after treatment. Psoriasis Area Severity Index (PASI) scores, severity of each symptom and area of skin lesion and quality of life were assessed at baseline, 2 weeks, and 4 weeks. Adverse events were recorded during the study. SAS 9.4 software and SPSS 17.0 software was applied for data analysis. A total of 300 participants with psoriasis vulgaris of blood-heat syndrome were assessed for eligibility, and 294 were randomly assigned to the Pulian ointment and placebo group from six study centers. Full analysis set (FAS): after 4 weeks of treatment, there were significant differences between groups in PASI score and the separate score of skin lesion area, favoring Pulian ointment group (P  0.05). Per protocol set (PPS): There was no statistically significant difference in PASI score and separate score of each symptom and area of skin lesion between two groups (P > 0.05). Quality of life measured by Hamilton Anxiety Rating Scale (HAMA) and 36-Item Short Form Health Survey (SF-36) improved after treatment in both groups, but there was no significant difference between the two groups (P > 0.05). After being followed up for 8 weeks, the total relapse rates of the Pulian Ointment group and placebo group were 5.88 and 8.45%, respectively, and the difference was not statistically significant between the two groups (P > 0.05). No adverse event was observed in both groups throughout the study. Pulian Ointment seems effective and well tolerated in improving the

    Full Text Available Transient cortical blindness (TCB is a well known but rare complication of administration of contrast agent. In this case report, we present a 53-year-old woman who is a follow-up case of sarcoidosis and developed TCB with focal neurological symptoms following contrast-enhanced computed tomography scan. Magnetic resonance imaging revealed bilateral T2/Flair hyperintensities in parieto-occipital, high frontal, and cerebellar hemispheres with involvement of corpus callosum. Clinically and radiologically patient improved significantly in 4 days. The exact mechanism is still speculative and its possible relationship with posterior reversible encephalopathy syndrome is briefly discussed. The patient′s symptoms were presumed to be exacerbated by presence of hypertension, underlying autoimmune disorder, sepsis, and high osmolality of contrast agent. Though there is no definite evidence to suggest that a certain treatment regimen improves the natural history of this disease but control of risk factors can possibly prevent this rare but devastating complication.

    Full Text Available Celiac artery compression syndrome (CACS or median arcuate ligament (MAL syndrome is a rare vascular disease. The clinical manifestations of CACS include the triad of postprandial pain, vomiting, and weight loss. The pathogenesis of CACS is the external compression of celiac artery by the MAL or celiac ganglion. Moreover, some authors also reported the compression with different etiologies, such as neoplasms of pancreatic head, adjacent duodenal carcinoma, vascular aneurysms, aortic dissection, or sarcoidosis. In the literature, most cases of CACS were reported from Western countries. In contrast, this disease was seldom reported in Oriental countries or regions, including Taiwan. Superior mesenteric artery syndrome (SMAS is also a rare disease characterized by compression of the third portion of the duodenum by the SMA. The clinical features of SMAS are postprandial pain, vomiting, and weight loss. To date, there are no guidelines to ensure the proper treatment of patients with CACS because of its low incidence. Thus, tailored therapy for patients with CACS remains a challenge as well as the prediction of clinical response and prognosis. The aim of our present study was to investigate the clinical features, the association with SMAS, treatments, and outcomes of patients with CACS in a single institution in Taiwan.

    Colonoscopy outcome is limited by endoscope looping, which leads to patient discomfort, prolonged procedure, and increased sedation requirement. Traditional manual abdominal pressure is imprecise and manually intensive. A hands-free abdominal compression device (ACD) may improve colonoscopy outcome. We aimed to assess the effect of a novel ACD on colonoscopy outcomes compared to manual pressure. This was a prospective single-blinded study of patients undergoing outpatient colonoscopy. The ACD (N-Doe Pillow™) was applied on 50 consecutive patients. Endoscopists were blinded to device usage. Control cases using manual pressure were randomly selected in a 2:1 manner. Primary outcome was cecal intubation time. Secondary outcomes included sedation requirement and complications. Subgroup analyses evaluated ACD effect on endoscopists with different experiences and patients at higher risk of difficult colonoscopy. Fisher's exact and Student's t-tests were performed for univariate analyses. Multivariate analysis was performed using generalized linear regression. Fifty patients undergoing colonoscopy with ACD assistance were compared to 100 matched controls. Mean cecal intubation time was significantly reduced in the ACD group compared to controls (6.38 minutes versus 11.8 minutes, P ACD use was independently associated with reduction in cecal intubation time (β-coeff: -4.11, P = .007). Subgroup analyses revealed a trend toward increased improvement in cecal intubation time among junior endoscopists and obese patients. A novel, hands-free ACD significantly decreased cecal intubation time in this prospective, single-blinded, match-controlled study. A trend toward more improvement was seen among junior faculty, suggesting an application for trainees and/or endoscopists with smaller case volumes.

    Pain is the most common complication of orthodontic treatment. Low-level laser therapy (LLLT) has been suggested as a new analgesic treatment free of the adverse effects of analgesic medications. However, it is not studied thoroughly, and the available studies are quite controversial. Moreover, helium neon (He-Ne) laser has not been assessed before. This split-mouth placebo-controlled randomized clinical trial was performed on 16 male and 14 female orthodontic patients requiring bilateral upper canine retraction. The study was performed at a private clinic in Sari, Iran, in 2014. It was single blind: patients, orthodontist, and personnel were blinded of the allocations, but the laser operator (periodontist) was not blinded. Once canine retractor was activated, a randomly selected maxillary quarter received a single dose of He-Ne laser irradiation (632.8 nm, 10 mw, 6 j/cm(2) density). The other quarter served as the placebo side, treated by the same device but powered off. In the first, second, fourth, and seventh days, blinded patients rated their pain sensed on each side at home using visual analog scale (VAS) questionnaires. There was no harm identified during or after the study. Pain changes were analyzed using two- and one-way repeated-measures ANOVA, Bonferroni, and t-test (α = 0.01, β > 0.99). This trial was not registered. It was self-funded by the authors. Sixteen males and 11 females remained in the study (aged 12-21). Average pain scores sensed in all 4 intervals on control and laser sides were 4.06 ± 2.85 and 2.35 ± 1.77, respectively (t-test P laser therapy might reduce orthodontic pain caused by retracting maxillary canines.

    Genetic diagnosis of inherited metabolic disease is conventionally achieved through syndrome recognition and targeted gene sequencing, but many patients receive no specific diagnosis. Next-generation sequencing allied to capture of expressed sequences from genomic DNA now offers a powerful new diagnostic approach. Barriers to routine diagnostic use include cost, and the complexity of interpreting results arising from simultaneous identification of large numbers of variants. We applied exome-wide sequencing to an individual, 16-year-old daughter of consanguineous parents with a novel syndrome of short stature, severe insulin resistance, ptosis, and microcephaly. Pulldown of expressed sequences from genomic DNA followed by massively parallel sequencing was undertaken. Single nucleotide variants were called using SAMtools prior to filtering based on sequence quality and existence in control genomes and exomes. Of 485 genetic variants predicted to alter protein sequence and absent from control data, 24 were homozygous in the patient. One mutation – the p.Arg732X mutation in the WRN gene – has previously been reported in Werner's syndrome (WS). On re-evaluation of the patient several early features of WS were detected including loss of fat from the extremities and frontal hair thinning. Lymphoblastoid cells from the proband exhibited a defective decatenation checkpoint, consistent with loss of WRN activity. We have thus diagnosed WS some 15 years earlier than average, permitting aggressive prophylactic therapy and screening for WS complications, illustrating the potential of exome-wide sequencing to achieve early diagnosis and change management of rare autosomal recessive disease, even in individual patients of consanguineous parentage with apparently novel syndromes.

  7. Improved Tensor-Based Singular Spectrum Analysis Based on Single Channel Blind Source Separation Algorithm and Its Application to Fault Diagnosis

    Full Text Available To solve the problem of multi-fault blind source separation (BSS in the case that the observed signals are under-determined, a novel approach for single channel blind source separation (SCBSS based on the improved tensor-based singular spectrum analysis (TSSA is proposed. As the most natural representation of high-dimensional data, tensor can preserve the intrinsic structure of the data to the maximum extent. Thus, TSSA method can be employed to extract the multi-fault features from the measured single-channel vibration signal. However, SCBSS based on TSSA still has some limitations, mainly including unsatisfactory convergence of TSSA in many cases and the number of source signals is hard to accurately estimate. Therefore, the improved TSSA algorithm based on canonical decomposition and parallel factors (CANDECOMP/PARAFAC weighted optimization, namely CP-WOPT, is proposed in this paper. CP-WOPT algorithm is applied to process the factor matrix using a first-order optimization approach instead of the original least square method in TSSA, so as to improve the convergence of this algorithm. In order to accurately estimate the number of the source signals in BSS, EMD-SVD-BIC (empirical mode decomposition—singular value decomposition—Bayesian information criterion method, instead of the SVD in the conventional TSSA, is introduced. To validate the proposed method, we applied it to the analysis of the numerical simulation signal and the multi-fault rolling bearing signals.

    Twelve patients with duodenal ulcer were admitted to a double-blind double-dummy single dose study in which the H2-receptor antagonist effect of Cimetidine and the activity of Trithiozine, endowed with an unknown mechanism, on gastric acid secretion were compared. For the balanced incomplete block design each patient received two out of four treatments. The single doses tested were 200 and 400 mg of both drugs. Cimetidine reduced all the parameters investigated, while Trithiozine increased basal acid output and acid concentration and did not affect maximal and peak acid output, basal and maximal volume and maximal acid concentration. The multiple range comparison between mean adjusted differences of the four doses were significantly in favour of Cimetidine, except for PAO, basal volume and basal acid concentration, despite the remarkable percent difference between Cimetidine and Trithiozine. In this study, Cimetidine confirmed its inhibitory properties, and Trithiozine did not appear to be an antisecretory agent.

    Hearing is of utmost importance for normal speech and social development. Even children who have mild or unilateral permanent hearing loss may experience difficulties with understanding speech, as well as problems with educational and psycho-social development. The increasing advantages of middle-ear implant technologies are opening new perspectives for restoring hearing. Active middle-ear implants can be used in children and adolescents with hearing loss. In addition to the well-documented results for improving speech intelligibility and quality of hearing in sensorineural hearing loss active middle-ear implants are now successfully used in patients with conductive and mixed hearing loss. In this article we present a case of successful, single-stage vibroplasty, on the right side with the fixation of the FMT on the stapes and PORP CLiP vibroplasty on the left side in a 6-year-old girl with bilateral mixed hearing loss and multiple dyslalia associated with Franceschetti syndrome (mandibulofacial dysostosis). CT revealed bilateral middle-ear malformations as well as an atretic right and stenotic left external auditory canal. Due to craniofacial dysmorphia airway and (post)operative, management is significantly more difficult in patients with a Franceschetti syndrome which in this case favoured a single-stage bilateral procedure. No intra- or postoperative surgical complications were reported. The middle-ear implants were activated 4 weeks after surgery. In the audiological examination 6 months after surgery, the child showed 100% speech intelligibility with activated implants on each side.

    The aim of this study was to evaluate the plaque removal efficacy of four toothbrushes: the Philips Sonicare Elite with medium and mini brush heads, the Elmex Sensitive, and the American Dental Association (ADA) reference toothbrush. This study was a randomized, controlled, investigator-blinded, four-brush crossover design study, which examined plaque removal following a consecutive repeated use. All brushes were used on each participant in a randomly assigned quadrant of the mouth. A total of 90 subjects participated in the study. Prior to the experiment, they received a professional prophylaxis and were requested to refrain from toothbrushing for 48 h. Teeth were professionally brushed consecutively for 10 to 90 s per quadrant. A Turesky-modified Quigley Hein Index score was assessed at baseline and after each brushing interval by one blinded investigator. Results showed reduction of mean plaque scores for all brushes with time from 10 to 90 s. After 30 s (2-min whole mouth equivalent) of brushing, the Sonicare brushes cleaned 19, the ADA brush 16, and the Elmex Sensitive 10 of in average 28 tooth surfaces. With time, the number of additional cleaned surfaces decreased. Time is an important variable in the evaluation of plaque-removing efficacy since absolute efficacy increases with time and differs per toothbrush. No differences could be found between the two brush heads of the Sonicare.

    One hundred and ninety eight females aged 12-15 y were enrolled in an observer-blinded randomized trial to assess the immunogenicity and reactogenicity of the tetravalent HPV vaccine Gardasil® (group 2), in comparison to the bivalent HPV vaccine, Cervarix® (group 1), which was routinely offered in the national vaccination schedule at the time. Participants were blinded to treatment group until all 3 vaccinations had been given, while laboratory staff were masked during testing. For the majority of local and general reactions, recipients of both vaccines reported comparable frequencies. Local and systemic events were rarely of high severity, except for tenderness at the injection site which reached a severe level after at least one of the doses in 24% of the Cervarix® group and 7% of the Gardasil® group (p = 0.001 comparing groups). For most reactions, no dose response was recorded, except for swelling with higher reporting at dose 3 (17.7%) than dose 1 (3.1%) for Cervarix®. SAE reporting was low (n = 3) and considered unrelated to either vaccine. This paper supports the body of evidence that Gardasil® has an acceptable safety profile when compared with Cervarix® and other vaccines given in the national program.

    Full Text Available The present trial aimed to investigate the effects of pioglitazone on the serum level of asymmetric dimethylarginine (ADMA, a marker of endothelial function, and some indices of inflammation and glucose and lipid metabolism in nondiabetic metabolic syndrome patients. 104 eligible participants (57% female; age between 20 and 70 were enrolled in a double-blind placebo-controlled trial and were randomized to receive either pioglitazone (uptitrated to 30 mg/day or matching placebo for 24 weeks. Participants were clinically examined and a blood sample was obtained at baseline and at the end of the trial. Pioglitazone significantly improved C-reactive protein level irrespective of changes in insulin sensitivity. Compared with the placebo group, alanine and aspartate transaminases were decreased and high-density lipoprotein cholesterol was increased after treatment with pioglitazone. A considerably greater weight gain was also recorded in the intervention group. We failed to observe any significant changes in serum ADMA in either group and between groups with and without adjustment for age, sex, and components of the metabolic syndrome. In a nutshell, pioglitazone seems to have positive effects on lipid profile, liver transaminases, and systemic inflammation. However, its previously demonstrated endothelial function-improving properties do not seem to be mediated by ADMA.

    Blueberry consumption has been shown to have various health benefits in humans. However, little is known about the effect of blueberry consumption on blood pressure, endothelial function and insulin sensitivity in humans. The present study investigated the role of blueberry consumption on modifying blood pressure in subjects with metabolic syndrome. In addition, endothelial function and insulin sensitivity (secondary measurements) were also assessed. A double-blind and placebo-controlled study was conducted in 44 adults (blueberry, n = 23; and placebo, n = 21). They were randomized to receive a blueberry or placebo smoothie twice daily for six weeks. Twenty-four-hour ambulatory blood pressure, endothelial function and insulin sensitivity were assessed pre- and post-intervention. The blood pressure and insulin sensitivity did not differ between the blueberry and placebo groups. However, the mean change in resting endothelial function, expressed as reactive hyperemia index (RHI), was improved significantly more in the group consuming the blueberries versus the placebo group (p = 0.024). Even after adjusting for confounding factors, i.e., the percent body fat and gender, the blueberry group still had a greater improvement in endothelial function when compared to their counterpart (RHI; 0.32 ± 0.13 versus -0.33 ± 0.14; p = 0.0023). In conclusion, daily dietary consumption of blueberries did not improve blood pressure, but improved (i.e., increased) endothelial function over six weeks in subjects with metabolic syndrome.

    The aim of this study was to investigate the effectiveness of short wave diathermy (SWD) in patients with subacromial impingement syndrome. In this double-blinded, randomized, placebo-controlled trial, 57 patients (aged 35-65 yrs) were classified into night pain positive (NP[+]) (n = 28) and night pain negative (NP[-]) (n = 29) groups. Both groups were randomly assigned to SWD (NP[+], n = 14; NP[-], n = 14) and sham (NP[+], n = 15; NP[-], n = 14) subgroups. Visual analog scale, Constant-Murley Scale (CS), and Shoulder Disability Questionnaire (SDQ) scores were used for evaluation. There was only a significant difference in pain with activity at 1-mo (mean difference [MD], -1.65; 95% confidence interval, -3.01 to -0.28]) and 2-mo evaluations (MD, -2.1; 95% confidence interval, -3.51 to -0.69) between SWD versus sham groups. In the NP(+) SWD group, the CS pain score was significantly higher than in the NP(+) sham group at all evaluations after treatment. At 1 mo, the NP(-) SWD group showed significantly better pain, strength, total CS, and SDQ scores than the NP(-) sham group. At 2 mos, the pain, range of motion, strength, and total CS and SDQ scores were better in the NP(-) SWD group than in the NP(-) sham group (P impingement syndrome without NP.

    Benefits of recombinant human growth hormone (rhGH) alone or combined with glutamine in patients with intestinal failure because of short-bowel syndrome remain controversial. We explored effects of rhGH on whole-body protein metabolism in patients with short-bowel syndrome with intestinal failure (SBS-IF) to gain insight into its mechanism of action. Eight stable hyperphagic patients with severe SBS-IF received, in a double-blind, randomized crossover study, low-dose rhGH (0.05 mg · kg⁻¹ · d⁻¹) and a placebo for two 3-wk periods. Leucine and glutamine kinetics under fasting and fed conditions, fat-free mass (FFM), and serum insulin were determined on the final day of each treatment. rhGH increased FFM and nonoxidative leucine disposal (NOLD; an index of protein synthesis) (P de novo synthesis (P de novo synthesis and intestinal absorption increase glutamine availability over the physiologic range, suggesting that beneficial effects of rhGH in hyperphagic patients might be achieved without glutamine supplementation. © 2014 American Society for Nutrition.

    The influence of dietary fiber on determinants of metabolic syndrome is controversial. The objective of this study was to determine the effects of NUTRIOSE supplementation on insulin resistance and the determinants of metabolic syndrome in overweight men. In this double-blind, randomized, placebo-controlled study, we supplemented the diets of overweight Chinese men with 250 mL of fruit juice that contained NUTRIOSE (Test group: n = 60, age = 30.4 ± 4.3 years, body mass index (BMI) = 24.5 ± 0.2 kg·m-2) or a maltodextrin placebo ( n = 60, age = 31.6 ± 4.1 years, BMI = 24.5 ± 0.3 kg·m-2) at a dosage of 17 g twice daily for 12 weeks. Daily caloric intake, body composition, blood chemistry, and blood pressure were evaluated every 4 weeks during the trial. Test subjects consumed fewer calories per day and had greater reductions in body weight, BMI, body fat percentage, and waist circumference than Control subjects. All markers of glucose metabolism improved in the Test group, with increases in adiponectin and reductions in glucose, insulin, homeostasis model assessment-estimated insulin resistance, glycosylated hemoglobin, and glycated albumin (all p overweight men.

    Bilateral adrenalectomy is currently the only available treatment for adrenocorticotropic hormone (ACTH)-dependent Cushing’s syndrome (ectopic ACTH syndrome) that is refractory to pharmacologic therapy. We describe two patients with refractory ectopic ACTH syndrome who were treated with CT-guided percutaneous microwave ablation of both hyperplastic adrenal glands in a single session: One was not a surgical candidate, and the other had undergone unsuccessful surgery. Following the procedure, both patients achieved substantial decreases in serum cortisol, symptomatic improvement, and decreased anti-hypertensive medication requirements.

    This study aimed to evaluate the efficacy and safety of Ganoderma lucidum for the treatment of hyperglycaemia and other cardiovascular risk components of metabolic syndrome using a prospective, double-blind, randomised, placebo-controlled trial. Eighty-four participants with type 2 diabetes mellitus and metabolic syndrome were randomised to one of three intervention groups: Ganoderma lucidum, Ganoderma lucidum with Cordyceps sinensis, or placebo. The dosage was 3 g/day of Ganoderma lucidum, with or without Cordyceps sinensis, for 16 weeks. The primary outcome measure was blood glucose (glycosylated haemoglobin [HbA1c] and fasting plasma glucose [FPG]); a number of secondary outcome measures were also tested. Data from the two intervention groups were combined. The combined intervention had no effect on any of the primary (baseline-adjusted difference in means: HbA1c = 0.13%, 95% CI [−0.35, 0.60], p = 0.60; FPG = 0.03 mmol/L, 95% CI [−0.90, 0.96], p = 0.95) or secondary outcome measures over the course of the 16-week trial, and no overall increased risk of adverse events with either active treatment.

    Continuous administration of a dopamine agonist could be used to treat patients with restless legs syndrome. Our aim was to investigate the efficacy of transdermal rotigotine in the treatment of idiopathic restless legs syndrome. In this randomised, double-blind, placebo-controlled trial, 458 patients with moderate-to-severe idiopathic restless legs syndrome (average baseline International Restless Legs Syndrome Study Group severity rating scale [IRLS] sum score of 28.1) were randomly assigned to receive transdermal rotigotine 1 mg over 24 h (n=115), 2 mg over 24 h (n=112), or 3 mg over 24 h (n=114), or to receive placebo (n=117). Study medication was delivered via patches, applied once a day for 6 months. Randomisation was done with a computer-generated randomisation list, stratified by centre. Primary efficacy outcomes were absolute change from baseline to end of maintenance in IRLS sum score and in the clinical global impressions (CGI) item 1 score, assessed by analysis of covariance in the intention-to-treat population. This trial is registered with ClinicalTrials.gov, number NCT00136045. Efficacy analyses were done on 112 patients in the 1 mg group, 109 in the 2 mg group, 112 in the 3 mg group, and 114 in the placebo group. Mean change in IRLS sum score from baseline at the end of the maintenance phase was -13.7 (SE 0.9) in the 1 mg group, -16.2 (0.9) in the 2 mg group, -16.8 (0.9) in the 3 mg group, and -8.6 (0.9) in the placebo group (pserious adverse event that were deemed to be related to rotigotine: elevation of liver enzymes (one patient), worsening of tinnitus (one patient), non-response to anticoagulation (one patient), electrocardiogram changes (one patient), and application-site reactions (six patients). No admissions to hospital were needed for the application-site reactions, and they all resolved within a short time of patch removal without any other therapeutic intervention.

    Introduction Oral corticosteroids are the first-line treatment for idiopathic childhood nephrotic syndrome. Most children experience several relapses, needing repeated courses of corticosteroid therapy. This exposes them to side effects and long-term complications. For most patients, long-term prognosis is for complete resolution of the disease over time and maintenance of normal kidney function. Therefore, it is vital to focus on minimising adverse events of the disease and its therapy. Unfortunately, no randomised controlled trials are available to determine the optimal corticosteroid treatment of an infrequent relapse of nephrotic syndrome. Recent studies show that treatment schedules for the first episode can safely be shortened to 2 months. The hypothesis of the REducing STEroids in Relapsing Nephrotic syndrome (RESTERN) study is that a 4-week reduction of alternate-day steroids after inducing remission is effective and safe, reduces steroid exposure by 35% on average and is therefore preferable. Methods and analysis The RESTERN study is a nationwide, double-blind, randomised, placebo-controlled, non-inferiority intervention study. Children aged 1–18 years with a relapse of steroid-sensitive nephrotic syndrome are eligible for this study. Study subjects (n=144) will be randomly assigned to either current standard therapy in the Netherlands or a reduced prednisolone schedule. The primary outcome of the RESTERN study is the time to first relapse after the final prednisolone dose. The secondary outcomes are the number or relapses, progression to frequent relapsing or steroid dependent nephrotic syndrome and the cumulative dosage of prednisolone during the study period. Ethics and dissemination This non-inferiority trial will be performed in accordance with the Declaration of Helsinki and has been approved by the medical ethical committee of Arnhem-Nijmegen and the Dutch Competent Authority (Central Committee on Research Involving Human Subjects, CCMO

    Full Text Available Background. Common cold is one of the most frequently occurring illnesses in primary healthcare services and represents considerable disease burden. Common cold of Qi-deficiency syndrome (CCQDS is an important but less addressed traditional Chinese medicine (TCM pattern. We designed a protocol to explore the efficacy, safety, and optimal dose of Shen Guo Lao Nian Granule (SGLNG for treating CCQDS. Methods/Design. This is a multicenter, randomized, double-blind, placebo-controlled, phase II clinical trial. A total of 240 eligible patients will be recruited from five centers. Patients are randomly assigned to high-dose group, middle-dose group, low-dose group, or control group in a 1 : 1 : 1 : 1 ratio. All drugs are required to be taken 3 times daily for 5 days with a 5-day follow-up period. Primary outcomes are duration of all symptoms, total score reduction on Jackson’s scale, and TCM symptoms scale. Secondary outcomes include every single TCM symptom duration and score reduction, TCM main symptoms disappearance rate, curative effects, and comparison between Jackson’s scale and TCM symptom scale. Ethics and Trial Registration. This study protocol was approved by the Ethics Committee of Clinical Trials and Biomedicine of West China Hospital of Sichuan University (number IRB-2014-12 and registered with the Chinese Clinical Trial Registry (ChiCTR-IPR-15006349.

    Full Text Available Abstract Background Emerging attempts have been made to reduce operative trauma and improve cosmetic results of laparoscopic cholecystectomy. There is a trend towards minimizing the number of incisions such as natural transluminal endoscopic surgery (NOTES and single-port laparoscopic cholecystectomy (SPLC. Many retrospective case series propose excellent cosmesis and reduced pain in SPLC. As the latter has been confirmed in a randomized controlled trial, patient's satisfaction on cosmesis is still controversially debated. Methods/Design The SPOCC trial is a prospective, multi-center, double blinded, randomized controlled study comparing SPLC with 4-port conventional laparoscopic cholecystectomy (4PLC in elective surgery. The hypothesis and primary objective is that patients undergoing SPLC will have a better outcome in cosmesis and body image 12 weeks after surgery. This primary endpoint is assessed using a validated 8-item multiple choice type questionnaire on cosmesis and body image. The secondary endpoint has three entities: the quality of life 12 weeks after surgery assessed by the validated Short-Form-36 Health Survey questionnaire, postoperative pain assessed by a visual analogue scale and the use of analgesics. Operative time, surgeon's experience with SPLC and 4PLC, use of additional ports, conversion to 4PLC or open cholecystectomy, length of stay, costs, time of work as well as intra- and postoperative complications are further aspects of the secondary endpoint. Patients are randomly assigned either to SPLC or to 4PLC. Patients as well as treating physicians, nurses and assessors are blinded until the 7th postoperative day. Sample size calculation performed by estimating a difference of cosmesis of 20% (alpha = 0.05 and beta = 0.90, drop out rate of 10% resulted in a number of 55 randomized patients per arm. Discussion The SPOCC-trial is a prospective, multi-center, double-blind, randomized controlled study to assess cosmesis and body

    To compare the acceptability and efficacy of two methods of self administered bowel preparation for flexible sigmoidoscopy screening: a single phosphate enema and a single sachet of Picolax. Single blind, randomised trial. Endoscopy units of two general hospitals. 1442 men and women aged 55-64 years who had agreed to be screened by flexible sigmoidoscopy. MAIN OUTCOME MESURESs: Attendance rates, compliance with allocated preparations, adverse effects, quality of bowel preparation, procedure time, and yield of neoplasia. Compliance with the enema was higher than with the Picolax (608 (84%) v 566 (79%); difference 6%, 95% confidence interval 2% to 10%). Almost half of those who refused Picolax used an enema at home. Wind, incontinence, and sleep disturbance were more frequent in the Picolax group than the enema group; bottom soreness was more frequent in the enema group. Around 30% (187) found the diet restriction required by Picolax difficult; 78% (471) found the enema easy to administer. The quality of preparation was better with the enema; the proportion of procedures complete to the descending colon was greater and the mean duration of the procedure was shorter. There was no significant difference in polyp detection rates. A single phosphate enema self administered around one hour before leaving home is a more acceptable and effective method of preparing the distal bowel for flexible sigmoidoscopy than Picolax.

    Full Text Available Aims: To evaluate the role of oral ketotifen and topical antibiotic therapy in the management of pruritus in prurigo nodularis (PN patients. Materials and Methods: Twenty-seven patients with PN and a history of atopy with raised IgE were included in this study in a dermatology clinic. All patients had positive growth of Staphylococcus aureus on the lesional skin swab. All patients received topical halobetasol and oral hydroxyzine for 4 weeks. In addition, all patients in the study group received oral ketotifen and topical antibiotic therapy for 4 weeks. Randomization was performed by using a table of random numbers, and the participants were randomly allocated to one of the two groups in the study. The study was a single-blind study, and the blinding was done by the investigator. Results: Of the 14 patients in the study group, 9 had complete relief from pruritus by the end of first week, which was maintained till the end of 4 weeks. In the control group, mild to moderate reduction in the intensity of pruritus in the PN lesions of all patients were noted by the end of the first week. No further improvement in the level of pruritus was noted in the participants during the trial period. The treatment was well tolerated by the patients, and the adverse reactions of drugs were minimal in both groups. Conclusions: This study showed that oral ketotifen and topical antibiotic therapy can be helpful in the management of pruritus in PN patients.

    Uterus didelphys with obstructed hemivagina and ipsilateral renal agenesis is a rare entity, sometimes referred to as Herlyn-Werner-Wunderlich syndrome (HWW). It usually presents after menarche with progressive pelvic pain, sometimes with regular menses, and a palpable mass due to hemihaematocolpos. The diagnosis is generally made only if the suspicion of this genitourinary syndrome is raised. To highlight the imaging diagnostic clues in this rare condition. We report on 11 adolescents with this condition. Sonography mostly allowed the correct diagnosis by showing uterovaginal duplication, haematocolpos or haematometrocolpos, and the absence of the ipsilateral kidney. MRI provided more detailed information regarding uterine morphology, the continuity with each vaginal channel (obstructed and nonobstructed), and the bloody nature of the contents. Early and accurate diagnosis of this syndrome is important so that adequate and prompt surgical therapy (excision of the vaginal septum) can provide relief of pain and prevent further complications. It is also advisable to look for an obstructed Muellerian system whenever a multicystic dysplastic kidney or the absence of a kidney is discovered in a fetus, or girl postnatally. (orig.)

    Full Text Available Understanding the nature of attentional processing in children with Down Syndrome (DS is imperative for developing effective education practices. The aim of the current study was to investigate whether children with DS exhibit impairment in sustained, transient, single-, or dual-target continuous performance tasks. Target detection time and accuracy was compared in children with DS to Typically Developing (TD children of similar nonverbal mental age (as measured by the Raven's Coloured Progressive Matrices, on single and dual- target continuous performance tasks measuring sustained attention, a visual change detection task measuring transient attention, and feature and conjunctive visual search tasks measuring both sustained and transient attention. Results showed that children with DS performed similarly to TD children on sustained and transient attention tasks that only required the detection of a single unique target, but were impaired in overall accuracy on tasks that required dual-target detection. Findings suggest a possible impairment in attention and working memory in children with DS. Error analysis of task responses revealed differences in problem solving strategy between children with DS and TD children, despite similar overall performance. Findings have implications for the education of children with DS and understanding of the nature of intellectual disability per se.

    In many regions where soil-transmitted helminth infections are endemic, single-dose albendazole is used in mass drug administration programs to control infections. There are little data on the efficacy of the standard single-dose administration compared to that of alternative regimens. We conducted a randomized, controlled, assessor-blinded clinical trial to determine the efficacies of standard and extended albendazole treatment against soil-transmitted helminth infection in Gabon. A total of 175 children were included. Adequate cure rates and egg reduction rates above 85% were found with a single dose of albendazole for Ascaris infection, 85% (95% confidence interval [CI], 73, 96) and 93.8% (CI, 87.6, 100), respectively, while two doses were necessary for hookworm infestation (92% [CI, 78, 100] and 92% [CI, 78, 100], respectively). However, while a 3-day regimen was not sufficient to cure Trichuris (cure rate, 83% [CI, 73, 93]), this regimen reduced the number of eggs up to 90.6% (CI, 83.1, 100). The rate ratios of two- and three-dose regimens compared to a single-dose treatment were 1.7 (CI, 1.1, 2.5) and 2.1 (CI, 1.5, 2.9) for Trichuris and 1.7 (CI, 1.0, 2.9) and 1.7 (CI, 1.0, 2.9) for hookworm. Albendazole was safe and well tolerated in all regimens. A single-dose albendazole treatment considerably reduces Ascaris infection but has only a moderate effect on hookworm and Trichuris infections. The single-dose option may still be the preferred regimen because it balances efficacy, safety, and compliance during mass drug administration, keeping in mind that asymptomatic low-level helminth carriage may also have beneficial effects.

    This paper aims to describe clinical and laboratory features and disease outcome in a single-centre cohort of patients with PFAPA syndrome (Periodic Fever, Aphtous stomatitis, Pharyngitis, and Adenitis) and to test performance of diagnostic and therapeutic algorithms. Patients fulfilling criteria were selected from the fever clinic population. Prospective follow-up together with recruitment of newly diagnosed patients followed pre-defined guidelines. Diagnostic and therapeutic algorithms and definitions of outcome and therapy response were formulated. Paired blood samples during febrile and afebrile periods were compared. Out of 176 patients referred for suspected periodic fever 125 children fulfilled criteria. Their age at onset was 23 months, median episode duration 3.5 days at 4-week intervals. Fever was associated with pharyngitis (91%), cervical adenitis (78%) and aphtae (41%). Among therapeutic options, episodic prednisone proved to be the most common first-line treatment. Administered to 77 patients, it reduced symptoms in 94%. Tonsillectomy led to the full symptom resolution in all 18 patients. Forty-six patients reached disease remission. Distribution of typical symptoms, response to therapies and disease outcome in a large patient cohort were documented. We offer diagnostic and therapeutic algorithms that have proven effective during this prospective trial. Our findings support the general belief of benign nature of this aetiologically unclear condition, despite proportion of patients having persistent disease for years. Maintenance of normal findings in afebrile intervals, striking response to a single dose of prednisone and normal growth and development together with spontaneous tendency towards prolongation of afebrile intervals are important confirmatory features of PFAPA syndrome.

    Prader-Willi syndrome (PWS) is known for hyperphagia with impaired satiety and a specific behavioural phenotype with stubbornness, temper tantrums, manipulative and controlling behaviour and obsessive-compulsive features. PWS is associated with hypothalamic and oxytocinergic dysfunction. In humans without PWS, intranasal oxytocin administration had positive effects on social and eating behaviour, and weight balance. To evaluate the effects of intranasal oxytocin compared to placebo administration on social behaviour and hyperphagia in children with PWS. Randomized, double-blind, placebo-controlled, crossover study in a PWS Reference Center in the Netherlands. Crossover intervention with twice daily intranasal oxytocin (dose range 24-48 IU/day) and placebo administration, both during 4 weeks, in 25 children with PWS (aged 6 to 14 years). In the total group, no significant effects of oxytocin on social behaviour or hyperphagia were found, but in the 17 children younger than 11 years, parents reported significantly less anger (P = 0·001), sadness (P = 0·005), conflicts (P = 0·010) and food-related behaviour (P = 0·011), and improvement of social behaviour (P = 0·018) during oxytocin treatment compared with placebo. In the eight children older than 11 years, the items happiness (P = 0·039), anger (P = 0·042) and sadness (P = 0·042) were negatively influenced by oxytocin treatment compared to placebo. There were no side effects or adverse events. This randomized, double-blind, placebo-controlled study suggests that intranasal oxytocin administration has beneficial effects on social behaviour and food-related behaviour in children with PWS younger than 11 years of age, but not in those older than 11 years of age. © 2016 The Authors.

    Although interferential current (IFC) is a common electrotherapeutic modality used to treat musculoskeletal pain, there is not any randomized controlled trial investigating its clinical efficacy in subacromial impingement syndrome (SAIS). Investigation of effectiveness of IFC treatment in patients with SAIS. Randomized, double-blind, sham-controlled study. Physical medicine and rehabilitation outpatient clinic. Patients (n=65) between 25 and 65 years of age, with a diagnosis of SAIS according to clinical evaluation and subacromial injection test. Patients were randomly distributed into two groups: 1) active IFC group (n=33); 2) sham IFC group (n=32). Exercise, cryotherapy, and a non-steroidal anti-inflammatory drug (NSAID) were given to both groups. Ten sessions of IFC with bipolar method were applied to the active IFC group daily 20 minutes per session, 5 days per week, for 2 weeks while sham IFC was applied to the sham IFC group with the same protocol. Visual analog scale (VAS), Constant scores, and Shoulder Disability Questionnaire (SDQ) were used for evaluation at baseline, immediately post-treatment, and 1 month post-treatment. Both the patients and the researcher who assessed the outcomes were blinded to the treatment protocol throughout the study period. Sixty of the 65 patients (active IFC group n=30, sham IFC group n=30) completed the study, 3 patients from active IFC, 2 from sham IFC group dropped during the follow up period. Statistically significant improvement was observed in all parameters of both groups immediately and 1 month post-treatment (p0.05). Our results demonstrated that IFC therapy does not provide additional benefit to NSAID, cryotherapy, and exercise program in treatment of SAIS. Our study responds to the needs of the lack of evidence in the field of rehabilitation. IFC therapy does not provide additional benefit for the treatment of SAIS.

    OBJECTIVE: To evaluate the efficacy of pancrealipase (PEZ) compared with placebo in the reduction of postprandial irritable bowel syndrome-diarrhoea (IBS-D). DESIGN: An intention to treat, double blind, randomised, crossover trial comparing PEZ to placebo for reduction of postprandial IBS-D. Patients had to recognise at least two different triggering foods, be willing to consume six baseline 'trigger meals' and again blinded with PEZ and placebo. Patients then chose which drug they preferred for another 25 meals. SETTING: Outpatient internal medicine practice clinic. PATIENTS: 255 patients were screened; 83 met the criteria, including 5 years of symptoms, recognised 'food triggers', no other identifiable cause for the symptoms, either a normal colonoscopy or barium enema while symptomatic and able to discontinue all anticholinergic medications. 69 patients were enrolled, 20 withdrew before randomisation, leaving 49 patients: 14 men, 35 women, mean age 52 years (SD 15.3). Over 60% had experienced symptoms for 11-30 years and 16% for more than 40 years. INTERVENTIONS: After completing six baseline meals, patients were randomised in blocks of four to receive either identical PEZ or a placebo for another six meals, and after a washout period of time received the alternative drug. MAIN OUTCOME MEASURES: The primary analysis was number of patients who chose PEZ over placebo for the extended use. RESULTS: Overall, 30/49 (61%) would have chosen PEZ (p=0.078), with first drug preference for PEZ at 0.002. Among the PEZ subgroup, PEZ use compared with placebo, demonstrated improvement in all symptoms (p≤0.001) for cramping, bloating, borborygami, urge to defecate, global pain and decrease stooling with increase in stool firmness. CONCLUSIONS: PEZ was found in a small group of patients to reduce postprandial IBS-D symptoms and deserves further evaluation.

    This is a constructive replication of a previous trial conducted by Bowden et al. (2010), where students who had received Reiki demonstrated greater health and mood benefits than those who received no Reiki. The current study examined impact on anxiety/depression. 40 university students—half with high depression and/or anxiety and half with low depression and/or anxiety—were randomly assigned to receive Reiki or to a non-Reiki control group. Participants experienced six 30-minute sessions over a period of two to eight weeks, where they were blind to whether noncontact Reiki was administered as their attention was absorbed in a guided relaxation. The efficacy of the intervention was assessed pre-post intervention and at five-week follow-up by self-report measures of mood, illness symptoms, and sleep. The participants with high anxiety and/or depression who received Reiki showed a progressive improvement in overall mood, which was significantly better at five-week follow-up, while no change was seen in the controls. While the Reiki group did not demonstrate the comparatively greater reduction in symptoms of illness seen in our earlier study, the findings of both studies suggest that Reiki may benefit mood.

    Ketoprofen, 25, 50, and 100 mg, was compared with 90 mg codeine and placebo for relief of pain due to removal of impacted third molar teeth. Treatment was self-administered as a single oral dose under double-blind conditions in five parallel groups established by a random code in healthy young adults. Based on 129 patient evaluations of pain experience and pain relief, ketoprofen was shown to have a more rapid onset and longer duration of action than codeine. In the derived variables of SPID (Sum of Pain Intensity Differences) and TOPAR (Total Pain Relief), all three doses of ketoprofen, with no dose-related differences among them, were found to provide statistically superior analgesia to codeine and placebo. All five treatments were associated with some adverse reactions.

    Full Text Available Recently bright-light control of the SSPD has been demonstrated. This attack employed a “backdoor” in the detector biasing scheme. Under bright-light illumination, SSPD becomes resistive and remains “latched” in the resistive state even when the light is switched off. While the SSPD is latched, Eve can simulate SSPD single-photon response by sending strong light pulses, thus deceiving Bob. We developed the experimental setup for investigation of a dependence on latching threshold of SSPD on optical pulse length and peak power. By knowing latching threshold it is possible to understand essential requirements for development countermeasures against blinding attack on quantum key distribution system with SSPDs.

    Tobacco smoking, a habitual behavior, is addictive and detrimental to health. Quitting requires personal abilities and environmental opportunities and therefore, improving these abilities and opportunities will undoubtedly act on smokers' motivation to quit. A prospective single-blinded randomized controlled interventional study was conducted among first year undergraduate students in Malaysia. A total of eighty smokers were randomly allocated to a control or intervention groups (40/40). Randomization remained concealed from research personnel. All participants were followed up for six months to evaluate abstinence. Quit line enrolment rate of the intervention group was 55% (22) compared to 7.5% (3) in the control (P smoking cessation is more effective than an information leaflet alone to promote quitting and that to maintain abstinence quit line follow up is necessary. Larger samples size and longer follow up studies are needed to further confirm these findings.

  4. Blind Astronomers

    The phrase "blind astronomer” is used as an allegorical oxymoron. However, there were and are blind astronomers. What of famous blind astronomers? First, it must be stated that these astronomers were not martyrs to their craft. It is a myth that astronomers blind themselves by observing the Sun. As early as France's William of Saint-Cloud (circa 1290) astronomers knew that staring at the Sun was ill-advised and avoided it. Galileo Galilei did not invent the astronomical telescope and then proceed to blind himself with one. Galileo observed the Sun near sunrise and sunset or through projection. More than two decades later he became blind, as many septuagenarians do, unrelated to their profession. Even Isaac Newton temporarily blinded himself, staring at the reflection of the Sun when he was a twentysomething. But permanent Sun-induced blindness? No, it did not happen. For instance, it was a stroke that left Scotland's James Gregory (1638-1675) blind. (You will remember the Gregorian telescope.) However, he died days later. Thus, blindness little interfered with his occupation. English Abbot Richard of Wallingford (circa 1291 - circa 1335) wrote astronomical works and designed astronomical instruments. He was also blind in one eye. Yet as he further suffered from leprosy, his blindness seems the lesser of Richard's maladies. Perhaps the most famous professionally active, blind astronomer (or almost blind astronomer) is Dominique-Francois Arago (1786-1853), director until his death of the powerful nineteenth-century Paris Observatory. I will share other _ some poignant _ examples such as: William Campbell, whose blindness drove him to suicide; Leonhard Euler, astronomy's Beethoven, who did nearly half of his life's work while almost totally blind; and Edwin Frost, who "observed” a total solar eclipse while completely sightless.

    To compare the efficacy and safety of a new porcine-derived pulmonary surfactant developed by Instituto Butantan with those of animal-derived surfactants commercially available in Brazil, regarding neonatal mortality and the major complications of prematurity in preterm newborns with birth weight up to 1500g and diagnosed with respiratory distress syndrome. Neonates diagnosed with respiratory distress syndrome were randomized to receive either Butantan surfactant (Butantan group) or one of the following surfactants: Survanta® or Curosurf®. Newborns receiving Survanta® or Curosurf® comprised the control group. The main outcome measures were mortality rates at 72 hours and at 28 days of life; the typical complications of prematurity as evaluated on the 28th day of life were defined as secundary outcomes. No differences were observed between the Butantan (n=154) and control (n=173) groups in relation to birth weight, gestational age, sex, and prenatal use of corticosteroids, or in mortality rates both at 72 hours (14.19% versus 14.12%; p=0.98) and at 28 days (39.86% versus 33.33%; p=0.24) of life. Higher 1- and 5-minute Apgar scores were observed among control group newborns. No differences were observed as regards the secondary outcomes, except for greater need for supplemental oxygen and a higher incidence of interstitial pulmonary emphysema in the Butantan group. The mortality rates at 72 hours and 28 days of life and the incidence of major complications of prematurity were comparable to those found with the animal-derived surfactants commercially available in Brazil, showing the efficacy and safety of the new surfactant in the treatment of respiratory distress syndrome in newborns.

    Full Text Available Patello-femoral pain syndrome (PFPS is a common knee joint disability. The integration of hip soft tissue regimens are not always emphasized, although current literature implies that there is a significant relationship between the two and there is a lack of randomized clinical trials to substantiate this relationship in clinical practice. A randomized controlled assessor blinded trial was designed to explore different rehabilitation programs related to PFPS. The study was conducted at RAZIEL institute of physical therapy, Netania, Israel with a total of 30 consecutive patients (mean age 35y, diagnosed with PFPS. All patients were randomly allocated into 3 groups. Group I conventional knee rehabilitation program. Included quadriceps strengthening and Trans Electric Neuromuscular Stimulation (TENS. Group II hip oriented rehabilitation program. included stretching, Hip external rotators strengthening and TENS. Group III a combination of the two above programs. Pain and function were documented on initial of the program and again 3 weeks later, on the completion. Pain was assessed by a numeric visual analogue scale (VAS; function was assessed by Patello-femoral joint evaluation scale (PFJES (0-100 points. At end of trial, all groups showed significant improvements in VAS and PFJES (p<0.0001; these improvements did not vary significantly between the 3 groups. The conclusions were that the explored different rehabilitation programs showed a similar beneficial effect.

    malnutrition is an important risk factor for poor outcome in patients recovering after hip fracture surgery. This study aimed to investigate the clinical, nutritional and rehabilitation effects of an oral nutritional supplementation (ONS) in an inpatient rehabilitation setting. this was an observer-blinded randomised controlled trial of elderly post-surgical proximal femoral fracture patients. A ready-to-use oral liquid nutritional supplementation (18-24 g protein and 500 kcal per day) in addition to hospital diet was compared with hospital diet only. Both groups received usual rehabilitation therapy and oral calcium and vitamin D supplements. Outcomes were compared at discharge from rehabilitation and after 4 weeks of discharge. The primary outcome parameters were the serum albumin level, the body mass index (BMI), the functional independence measure (FIM) and the elderly mobility scale (EMS). Secondary outcome parameters were frequency of complications, inpatient length of stay, mortality and acute hospital use within 6 months after discharge. a total of 126 patients were recruited, 65 in the supplementation arm and 61 in the control arm. There was a significant difference in change in BMI with a decrease of 0.25 and 0.03 kg/m(2) in the ONS group and 0.72 and 0.49 kg/m(2) in the control group at hospital discharge and follow-up, respectively (P = 0.012). The length of stay in rehabilitation ward was shortened by 3.80 (SE = 1.81, P = 0.04) days favouring the ONS group. The total number of infection episodes was also reduced significantly. No difference was observed in the rate of change of the serum albumin level, the FIM and the EMS. clinical and nutritional benefits were seen in this trial but rehabilitation benefits could not be demonstrated.

The aim of this study was to investigate the effectiveness of 850-nm gallium arsenide aluminum (Ga-As-Al laser therapy on pain, range of motion and disability in subacromial impingement syndrome. METHODS: A total of 52 patients (33 females and 19 males with a mean age of 53.59±11.34 years with subacromial impingement syndrome were included. The patients were randomly assigned into two groups. Group I (n = 30, laser group received laser therapy (5 joule/cm² at each point over maximum 5-6 painful points for 1 minute. Group II (n = 22, placebo laser group received placebo laser therapy. Initially cold pack (10 minutes was applied to all of the patients. Also patients were given an exercise program including range of motion, stretching and progressive resistive exercises. The therapy program was applied 5 times a week for 14 sessions. Pain severity was assessed by using visual analogue scale. Range of motion was measured by goniometer. Disability was evaluated by using Shoulder Pain and Disability Index. RESULTS: In group I, statistically significant improvements in pain severity, range of motion except internal and external rotation and SPADI scores were observed compared to baseline scores after the therapy (p0.05. CONCLUSIONS: The Low level laser therapy seems to have no superiority over placebo laser therapy in reducing pain severity, range of motion and functional disability.

    Restless legs syndrome (RLS) is a common disorder in hemodialysis patients that leads to insomnia and impaired quality of life. Because high oxidative stress has been implicated in the pathogenesis of RLS, we sought to evaluate the efficacy of vitamins C and E and their combination in reducing the severity of RLS symptoms in hemodialysis patients in this randomized, double-blind, placebo-controlled, four-arm parallel trial. Sixty stable hemodialysis patients who had all four diagnostic criteria for RLS developed by the International Restless Legs Syndrome Group with no acute illness or history of renal stone were randomly allocated to four fifteen-patient parallel groups to receive vitamin C (200 mg) and vitamin E (400 mg), vitamin C (200 mg) and placebo, vitamin E (400 mg) and placebo, and double placebo daily for eight weeks. International Restless Legs Scale (IRLS) scores were measured for all patients at baseline and at the end of treatment phase. The primary outcome was absolute change in IRLS sum score from baseline to the end of treatment phase. Means of IRLS sum score decreased significantly in the vitamins C and E (10.3 ± 5.3, 95% CI: 7.4-13.3), vitamin C and placebo (10 ± 3.5, 95% CI: 8.1-11.9), and vitamin E and placebo groups (10.1 ± 6, 95% CI: 6.8-13.5) compared with the double placebo group (3.1 ± 3, 95% CI: 1.5-4.8), (PVitamins C and E and their combination are safe and effective treatments for reducing the severity of RLS in hemodialysis patients over the short-term.

    The objective of this study was to compare the efficacy of subacromial injection of triamcinolone compared to injection of ketorolac in the treatment of external shoulder impingement syndrome. Thirty-two patients diagnosed with external shoulder impingement syndrome were included in this double-blinded randomized controlled clinical trial. Each patient was randomized into the steroid group or nonsteroidal anti-inflammatory drugs (NSAID) group. The steroid syringe contained 40 mg triamcinolone; and the NSAID syringe contained 60 mg ketorolac. Each patient was evaluated in terms of arc of motion, visual analog scale (VAS) for evaluating pain, and the UCLA (The University of California at Los Angeles) shoulder rating scale. At 1 month follow-up, both treatment arms resulted in increased range of motion and decreased pain. The steroid group decreased in active abduction while the NSAID group increased (steroid: 134°, NSAID: 151°, P = .03). The mean improvement in the UCLA shoulder rating scale at 4 weeks was 7.15 for the NSAID group and 2.13 for the steroid group (P = .03). Subgroup analysis of the UCLA scale demonstrated an increase in both forward flexion strength (P = .04) and patient satisfaction (P = .03) in the NSAID group. No significant difference could be seen in all other outcome measures. In this study, an injection of ketorolac resulted in greater improvements in the UCLA shoulder rating scale than an injection of triamcinolone at 4 weeks follow-up. While both triamcinolone and ketorolac are effective in the treatment of isolated subacromial impingement, ketorolac appears to have equivalent if not superior efficacy; all the while decreasing patient exposure to the potential side-effects of corticosteroids.

    Phelan-McDermid syndrome (PMS) or 22q13.3 deletion syndrome is a rare neurodevelopmental disorder with at least 60 children and 35 adults diagnosed in the Netherlands. Clinical features are moderate to severe intellectual disability and behavioural problems in the autism spectrum. Other researchers had observed a beneficial effect of intranasal insulin on development and behaviour in a pilot study in six children with PMS. To validate this effect, we conducted a randomized, double-blind, placebo-controlled clinical trial using a stepped-wedge design. From March 2013 to June 2015, 25 children aged 1-16 years with a molecularly confirmed 22q13.3 deletion including the SHANK3 gene participated in the clinical trial for a period of 18 months. Starting 6 months before the trial, children were systematically assessed for cognitive, language and motor development and for adaptive, social and emotional behaviour every 6 months. The second, third and fourth assessments were followed by daily nose sprays containing either intranasal insulin or intranasal placebo for a 6-month period. A fifth assessment was done directly after the end of the trial. Intranasal insulin did not cause serious adverse events. It increased the level of developmental functioning by 0.4-1.4 months per 6-month period, but the effect was not statistically significant in this small group. We found a stronger effect of intranasal insulin, being significant for cognition and social skills, for children older than 3 years, who usually show a decrease of developmental growth. However, clinical trials in larger study populations are required to prove the therapeutic effect of intranasal insulin in PMS.

    To determine whether children requiring special education represent a high-risk group for identifying Tourette's syndrome (TS), we performed direct examinations for the presence of tics in 35 special education and 35 regular classroom students from a single school district. Of the special education students, nine (26%) had definite or probable tics as compared with only two (6%) of the regular classroom students. About one-third of the students with tics currently meet diagnostic criteria for TS and probably more will do so in the future. About one-half of the subjects with tics have evidence of obsessive-compulsive behavior (OCB) or an attention-deficit hyperactivity disorder (ADHD). For three randomly selected students with definite tics, direct examinations of first-degree relatives revealed the presence of tics in all families. Subjects to the limitations of this pilot study, we conclude that TS and related tic disorders are commonly associated with the need for special education in this single school district. TS might also be an important contributor to school problems in the childhood population at large and may be a highly prevalent condition. In addition, we conclude that childhood tics are associated with OCB and ADHD, are genetically determined, and are part of the TS clinical spectrum.

    The efficacy of low-level laser therapy (LLLT) in myofascial pain syndrome (MPS) seems controversial. A prospective, double-blind, randomized controlled trial was conducted in patients with chronic MPS in the neck to evaluate the effects of low-level 830-nm gallium arsenide aluminum (Ga-As-Al) laser therapy. The study group consisted of 64 MPS patients. The patients were randomly assigned into two groups. In group 1 (n = 32), Ga-As-Al laser treatment was applied over three trigger points bilaterally for 2 min over each point once a day for 15 days during a period of 3 weeks. In group 2 (n = 32), the same treatment protocol was given, but the laser instrument was switched off during applications. All patients in both groups performed daily isometric exercise and stretching exercises for cervical region. Parameters were measured at baseline and after 4 weeks. All patients were evaluated with respect to pain (at rest, movement, and night) and assessed by visual analog scale, measurement of active range of motion using an inclinometer and a goniometer, and the neck disability index. In both groups, statistically significant improvements were detected in all outcome measures compared with baseline (p 0.05). In conclusion, although the laser therapy has no superiority over placebo groups in this study, we cannot exclude the possibility of effectivity with another treatment regimen including different laser wavelengths and dosages (different intensity and density and/or treatment interval).

Low-dose doxycycline (LDD inhibits MMPs. We evaluated the efficacy of LDD for the subjective symptoms in primary SS patients. This was a randomized, double blind, placebo controlled cross-over study. 22 patients were randomly assigned to receive either 20 mg LDD or matching placebo twice a day for 10 weeks. The first medication period was followed by 10-week washout period, after which the patient received either LDD or placebo, depending on the first drug received, followed by the second washout period. Stimulated saliva flow rates and pH were measured before and after one and ten weeks of each medication and after washout periods. VAS scale was used to assess the effect of LDD and placebo on following six subjective symptoms: xerostomia; xerophtalmia; difficulty of swallowing; myalgia; arthralgia; and fatigue. The effect was evaluated for each medication and washout period separately. Results Overall, the effects of medications on subjective symptoms were minor. Wilcoxon test demonstrated increased fatigue with LDD during medication (p Conclusion LDD may not be useful in reducing the primary SS symptoms.

    Short-chain fructooligosaccharides (scFOS) have beneficial effects in subjects with minor digestive complaints, but the potential mechanisms involved have not been elucidated. The aim of the study was to evaluate changes in rectal sensitivity related to the clinical effects of scFOS in a selected group of patients with irritable bowel syndrome (IBS) and rectal hypersensitivity. In 79 IBS patients (defined by Rome III criteria) with rectal hypersensitivity (defined as discomfort threshold ≤44 g) a parallel, placebo-controlled, randomized, and double-blind study was performed to assess the effects of dietary supplementation (5 g d -1 ) with scFOS vs placebo for 4 weeks on rectal sensitivity (primary outcome: tolerance to increasing wall tension applied by a tensostat), clinical outcomes (IBS, anxiety/depression and quality of life scores) and composition of fecal microbiota. Rectal discomfort threshold, and IBS and quality of life scores, significantly improved during treatment, but in a similar manner in both scFOS and placebo groups; a post-hoc analysis showed that the effect of scFOS on rectal sensitivity was more pronounced in constipation-predominant-IBS patients (P=.051 vs placebo). Contrary with placebo, scFOS significantly reduced anxiety scores and increased fecal Bifidobacteria (Pmicrobiota; demonstration of effects of scFOS on rectal sensitivity may require higher doses and may depend on the IBS subgroup. © 2016 The Authors.

    To evaluate the efficacy of topical chamomile oil in patients with mild and moderate carpal tunnel syndrome (CTS). Eighty six patients with electrodiagnostic criteria of mild and moderate CTS were enrolled in this randomized double-blind placebo-controlled clinical trial and received wrist splint plus topical chamomile oil or placebo for 4 weeks. They were evaluated at the baseline and end of the study regarding functional and symptomatic scores, dynamometry, and electrodiagnostic indexes. Dynamometry, functionality, and symptom severity scores of the patients were significantly improved in the chamomile oil group compared with the placebo group (P = 0.040, P = 0.0001, P = 0.017, respectively). Additionally, compound latency of the median nerve in the chamomile oil group significantly decreased (P = 0.035) compared to the placebo group. Other electerodiagnostic measurements did not change significantly. Complementary treatment with topical chamomile oil may have some benefits for patients with mild and moderate CTS, both subjectively and objectively. Copyright © 2016 Elsevier Ltd.

    To compare the effects of intraarticular (IA) injections of glycosaminoglycan polysulfate (GAGPS) plus basic conservative treatment with the effects of placebo injections plus conservative treatment and with the effects of conservative treatment alone in patients with chronic patellofemoral pain syndrome (PFPS). We treated 53 patients who presented with chronic PFPS in 1 knee, according to 1 of the 3 protocols, in a prospective, randomized, double-blind study. Basic conservative treatment consisted of a 6-week program of quadriceps muscle exercise, elimination of symptom-producing activities, and oral doses of nonsteroidal antiinflammatory drugs. Physiologic saline served as placebo for injection. During the 6-week treatment period, 5 injections were given 1 week apart. Along with measurements of quadriceps strength, standardized subjective, functional, and clinical assessments were performed at presentation, after 6 weeks of treatment, and after 6 months. Results at 6 months indicated that IA injections of GAGPS or saline did not result in significant improvement beyond the good results achieved by the basic conservative treatment alone. More than two-thirds of the patients in each group experienced complete recovery. Neither the GAGPS injections nor the physiologic saline injections are more effective than conservative therapy in the treatment of chronic PFPS. Restoration of normal quadriceps muscle function to the affected knee seems to be crucial in treating PFPS.

    Sporadic human basal cell carcinomas (BCC) are generally well managed with current surgical modalities. However, in the subset of high-risk patients predisposed to developing large numbers of BCCs, there is an unmet need for effective, low-morbidity chemoprevention. This population includes fair-skinned patients with extensive sun exposure and those with genodermatoses such as the basal cell nevus (Gorlin) syndrome (BCNS). Tazarotene (Tazorac, Allergan) is a topical retinoid with relative specificity for RAR-β and RAR-γ receptors. We previously demonstrated tazarotene's robust anti-BCC efficacy in Ptch1(+/-) mice, a murine equivalent of BCNS, and others have found it to have some efficacy against sporadic human BCCs. We report here results of a randomized, double-blind, vehicle-controlled study in patients with BCNS evaluating the efficacy of topically applied tazarotene for BCC chemoprevention (N = 34 subjects), along with an open-label trial evaluating tazarotene's efficacy for chemotherapy of BCC lesions (N = 36 subjects) for a maximum follow-up period of 3 years. We found that only 6% of patients had a chemopreventive response and that only 6% of treated BCC target lesions were clinically cured. Our studies provide no evidence for either chemopreventive or chemotherapeutic effect of tazarotene against BCCs in patients with BCNS.

    2014-01-01

    Background Primary Sjögren’s Syndrome (PSS) mainly affects women (9:1 female:male ratio) and is one of the commonest autoimmune diseases with a prevalence of 0.1 – 0.6% of adult women. For patients with PSS there is currently no effective therapy that can alter the progression of the disease. The aim of the TRACTISS study is to establish whether in patients with PSS, treatment with rituximab improves clinical outcomes. Methods/design TRACTISS is a UK multi-centre, double-blind, randomised, controlled, parallel group trial of 110 patients with PSS. Patients will be randomised on a 1:1 basis to receive two courses of either rituximab or placebo infusion in addition to standard therapy, and will be followed up for up to 48 weeks. The primary objective is to assess the extent to which rituximab improves symptoms of fatigue and oral dryness. Secondary outcomes include ocular dryness, salivary flow rates, lacrimal flow, patient quality of life, measures of disease damage and disease activity, serological and peripheral blood biomarkers, and glandular histology and composition. Discussion The TRACTISS trial will provide direct evidence as to whether rituximab in patients with PSS leads to an improvement in patient symptoms and a reduction in disease damage and activity.

    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 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.

    BACKGROUND AND OBJECTIVE: Neonatal respiratory distress syndrome (RDS) due to pulmonary surfactant deficiency is heritable, but common variants do not fully explain disease heritability. METHODS: Using next-generation, pooled sequencing of race-stratified DNA samples from infants ≥34 weeks’ gestation with and without RDS (n = 513) and from a Missouri population-based cohort (n = 1066), we scanned all exons of 5 surfactant-associated genes and used in silico algorithms to identify functional mutations. We validated each mutation with an independent genotyping platform and compared race-stratified, collapsed frequencies of rare mutations by gene to investigate disease associations and estimate attributable risk. RESULTS: Single ABCA3 mutations were overrepresented among European-descent RDS infants (14.3% of RDS vs 3.7% of non-RDS; P = .002) but were not statistically overrepresented among African-descent RDS infants (4.5% of RDS vs 1.5% of non-RDS; P = .23). In the Missouri population-based cohort, 3.6% of European-descent and 1.5% of African-descent infants carried a single ABCA3 mutation. We found no mutations among the RDS infants and no evidence of contribution to population-based disease burden for SFTPC, CHPT1, LPCAT1, or PCYT1B. CONCLUSIONS: In contrast to lethal neonatal RDS resulting from homozygous or compound heterozygous ABCA3 mutations, single ABCA3 mutations are overrepresented among European-descent infants ≥34 weeks’ gestation with RDS and account for ∼10.9% of the attributable risk among term and late preterm infants. Although ABCA3 mutations are individually rare, they are collectively common among European- and African-descent individuals in the general population. PMID:23166334

    It has been hypothesized that glutamatergic transmission may be altered in Tourette syndrome. In this study, we explored the efficacy of a glutamate agonist (D-serine) and antagonist (riluzole) as tic-suppressing agents in children with Tourette syndrome. We performed a parallel three-arm, 8-week, double-blind, randomized placebo-controlled treatment study in children with Tourette syndrome. Each child received 6 weeks of treatment with D-serine (maximum dose 30 mg/kg/day), riluzole (maximum dose 200 mg/day), or placebo, followed by a 2-week taper. The primary outcome measure was effective tic suppression as determined by the differences in the Yale Global Tic Severity Scale score; specifically, the total tic score and the combined score (total tic score + global impairment) between treatment arms after 6 weeks of treatment. Mann-Whitney U tests were performed to analyze differences between each group and the placebo group. Twenty-four patients (males = 21, ages 9-18) enrolled in the study; one patient dropped out before completion. Combined Yale Global Tic Severity Scale score and total tic scores improved in all groups. The 6-week mean percent improvement of the riluzole (n = 10), D-serine (n = 9), and placebo (n = 5) groups in the combined Yale Global Tic Severity Scale score were 43.7, 39.5, and 30.2 and for total tic scores were 38.0, 25.0, and 34.0, respectively. There were no significant differences in Yale Global Tic Severity Scale score or total tic score, respectively, between the riluzole and placebo (P = 0.35, 0.85) or D-serine and placebo (P = 0.50, 0.69) groups. Tics diminished by comparable percentages in the riluzole, D-serine, and placebo groups. These preliminary data suggest that D-serine and riluzole are not effective in tic suppression.

    With the association between increased carotenoid intake and lower risk of chronic diseases, the absorption of lutein from the diet becomes an important factor in its delivery and physiological action. The primary objective of this study was to gain an understanding of how a new formulation technology (mixture of mono- and diglycerides (MDG)), affected lutein absorption. Subjects (n 24) were randomised in a cross-over, double-blind study to receive a single dose of 6 mg lutein (FloraGLO 20 %) provided as capsules containing either high-oleic safflower (SAF) oil or a MDG oil. Subjects receiving a single dose of lutein in MDG showed a significantly greater change from baseline (0 h) to 4, 6, 8, 12, 24, 48 and 336 h (Plutein at 48 and 336 h (Plutein in SAF. Analysis of the 48 h absorption kinetics of lutein showed that the time to peak level of lutein (12 h) was the same for SAF and MDG groups, but the change in plasma lutein at 12 and 48 h were 129 and 320 % higher, respectively, for MDG compared with SAF. This difference continued as the adjusted AUC 0-48 and 0-336 h for the MDG group was 232 and 900 % higher, respectively, v. SAF. The study data show that by changing the lipid that is combined with a lutein supplement results in significant increases in lutein absorption in healthy adults.

    Full Text Available To effectively de-noise the Gaussian white noise and periodic narrow-band interference in the background noise of partial discharge ultra-high frequency (PD UHF signals in field tests, a novel de-noising method, based on a single-channel blind source separation algorithm, is proposed. Compared with traditional methods, the proposed method can effectively de-noise the noise interference, and the distortion of the de-noising PD signal is smaller. Firstly, the PD UHF signal is time-frequency analyzed by S-transform to obtain the number of source signals. Then, the single-channel detected PD signal is converted into multi-channel signals by singular value decomposition (SVD, and background noise is separated from multi-channel PD UHF signals by the joint approximate diagonalization of eigen-matrix method. At last, the source PD signal is estimated and recovered by the l1-norm minimization method. The proposed de-noising method was applied on the simulation test and field test detected signals, and the de-noising performance of the different methods was compared. The simulation and field test results demonstrate the effectiveness and correctness of the proposed method.

    Parenteral nutrition (PN) covering the need for carbohydrates, amino acids, and lipids can either be compounded from single nutrients or purchased as an industrially manufactured ready-to-use regimen. This study compares a commercially available 3-chamber bag (study group) with a conventionally compounded monobag regarding nutrition efficacy, safety, and regimen preparation time. This prospective, randomized, single-blind study was conducted at 5 Chinese hospitals from October 2010-October 2011. Postsurgical patients requiring PN for at least 6 days were randomly assigned to receive the study or control regimen. Plasma concentrations of prealbumin and C-reactive protein (CRP), regimen preparation time, length of hospital stay (LOS), 30-day mortality, safety laboratory parameters, and adverse events (AEs) were recorded. In total, 240 patients (121 vs 119 in study and control groups) participated in this study. Changes in prealbumin concentrations during nutrition support (Δ Prealb(StudyGroup) = 2.65 mg/dL, P values were comparable. Regimen preparation time was significantly reduced in the study group by the use of 3-chamber bags (t (StudyGroup) = 4.90 ± 4.41 minutes vs t (ControlGroup) = 12.13 ± 5.62 minutes, P bag was comparable to the compounded regimen and safe in use. Time savings during regimen preparation indicates that use of 3-chamber bags simplifies the process of regimen preparation.

    This study was designed to compare the Ambu Aura-i to the single-use LMA Fastrach regarding time to intubation, success rate, and airway morbidity in patients undergoing elective surgery requiring general anesthesia. Prospective, randomized controlled trial. Academic medical center. Sixty-five adult patients scheduled for elective surgery requiring general anesthesia. Patients were randomized into 2 groups. Group A (n=33) were intubated using Ambu Aura-i and the Ambu aScope 2, a disposable flexible intubating scope, whereas those in group B (n=33) were blindly intubated using the Intubating Laryngeal Mask Airway (ILMA). First-attempt intubation success rate, overall intubation success rate, time to intubation, incidence of airway morbidity. The data demonstrated that time for endotracheal intubation in the ILMA group was significantly shorter than in the Ambu Aura-i group (PAura-i=26/33, 78.8%; ILMA=27/33, 81.8%; P=.757) or the overall intubation success rate (Aura-i=29/33, 87.9%; ILMA=31/33, 93.9%; P=.392) between the groups. Four patients (12%) in the Ambu Aura-i group had a failed intubation; 1 was due to a failure of the aScope monitor, whereas 3 were due to inability to visualize the glottis. Two patients (7%) in the ILMA group had a failed intubation due to esophageal intubation. There was no statistically significant difference in airway morbidity between the 2 groups. The data suggest that intubation with the ILMA is faster but that first-attempt and overall intubation success rates were comparable in both groups. The results suggest that although the flexible intubating scope-guided Aura-i does not outperform blind intubation via the ILMA, the technique is comparable in terms of first-attempt and overall intubation success rate.

    A concern that arises with any new prosthesis is whether it will achieve satisfactory long-term implant stability. The gold standard of assessing the quality of fixation in a new or relatively new implant is to undertake a randomized controlled trial using radiostereometric analysis. It was hypothesized that both mobile-bearing total knee arthroplasty and fixed-bearing total knee arthroplasty have comparable migration patterns at 2-year follow-up. This study investigated two types of cemented total knee arthroplasty, the mobile- or fixed-bearing variant from the same family with use of radiostereometric analysis. This prospective, patient-blinded, randomized, controlled trial was designed to investigate early migration of the tibia component after two years of follow-up with use of radiostereometric analysis. A total of 50 patients were randomized to receive a mobile- or fixed-bearing TKA from the same family. Patients were evaluated during 2-year follow-up, including radiostereometric analysis, physical and clinical examination and patient reported outcome measures (PROMs). At two-year follow-up, the mean (±SD) maximum total point motion (MTPM) in the fixed-bearing group was 0.82 (±1.16) versus 0.92 mm (±0.64) in the mobile-bearing group (p = n.s) with the largest migration seen during the first 6 weeks (0.45 ± 0.32 vs. 0.54 ± 0.30). The clinical outcome and PROMs significantly improved within each group, not between both groups. Measuring early micromotion is useful for predicting clinical loosening that can lead to revision. The results of this study demonstrate that early migration of the mobile-bearing is similar to that of the fixed-bearing component at two years and was mainly seen in the first weeks after implantation. Randomized, single-blind, controlled trial, Level I.

    Patients with Lennox-Gastaut syndrome, a rare, severe form of epileptic encephalopathy, are frequently treatment resistant to available medications. No controlled studies have investigated the use of cannabidiol for patients with seizures associated with Lennox-Gastaut syndrome. We therefore assessed the efficacy and safety of cannabidiol as an add-on anticonvulsant therapy in this population of patients. In this randomised, double-blind, placebo-controlled trial done at 24 clinical sites in the USA, the Netherlands, and Poland, we investigated the efficacy of cannabidiol as add-on therapy for drop seizures in patients with treatment-resistant Lennox-Gastaut syndrome. Eligible patients (aged 2-55 years) had Lennox-Gastaut syndrome, including a history of slow (spike-and-wave patterns on electroencephalogram, evidence of more than one type of generalised seizure for at least 6 months, at least two drop seizures per week during the 4-week baseline period, and had not responded to treatment with at least two antiepileptic drugs. Patients were randomly assigned (1:1) using an interactive voice response system, stratified by age group, to receive 20 mg/kg oral cannabidiol daily or matched placebo for 14 weeks. All patients, caregivers, investigators, and individuals assessing data were masked to group assignment. The primary endpoint was percentage change from baseline in monthly frequency of drop seizures during the treatment period, analysed in all patients who received at least one dose of study drug and had post-baseline efficacy data. All randomly assigned patients were included in the safety analyses. This study is registered with ClinicalTrials.gov, number NCT02224690. Between April 28, 2015, and Oct 15, 2015, we randomly assigned 171 patients to receive cannabidiol (n=86) or placebo (n=85). 14 patients in the cannabidiol group and one in the placebo group discontinued study treatment; all randomly assigned patients received at least one dose of study treatment

    Improvements on balance, gait and cognition are some of the benefits of exergames. Few studies have investigated the cognitive effects of exergames in institutionalized older persons. To assess the acute effect of a single session of exergames on cognition of institutionalized older persons. Nineteen institutionalized older persons were randomly allocated to Wii (WG, n = 10, 86 ± 7 year, two males) or control groups (CG, n = 9, 86 ± 5 year, one male). The WG performed six exercises with virtual reality, whereas CG performed six exercises without virtual reality. Verbal fluency test (VFT), digit span forward and digit span backward were used to evaluate semantic memory/executive function, short-term memory and work memory, respectively, before and after exergames and Δ post- to pre-session (absolute) and Δ % (relative) were calculated. Parametric (t independent test) and nonparametric (Mann-Whitney test) statistics and effect size were applied to tests for efficacy. VFT was statistically significant within WG (-3.07, df = 9, p = 0.013). We found no statistically significant differences between the two groups (p > 0.05). Effect size between groups of Δ % (median = 21 %) showed moderate effect for WG (0.63). Our data show moderate improvement of semantic memory/executive function due to exergames session. It is possible that cognitive brain areas are activated during exergames, increasing clinical response. A single session of exergames showed no significant improvement in short-term memory, working memory and semantic memory/executive function. The effect size for verbal fluency was promising, and future studies on this issue should be developed. RBR-6rytw2.

    Asperger syndrome, a heritable condition entailing empathy deficits together with unusually narrow interests in individuals of normal or even above-average intelligence, was recognized only recently. Here we report the first-ever prospective study of a child born to two adults with a formal diagnosis of Asperger syndrome. The child's parents are both scientists (a mathematician and a chemist). The aim of study 1 was to test if the child also developed Asperger syndrome, given the heritability of the condition, and if Asperger syndrome can be detected at 26 months. At 18 months, the child was given the Checklist for Autism in Toddlers, and at 26 months, she was assessed diagnostically for autism spectrum conditions using the Autism Diagnostic Interview-Revised and the Autism Diagnostic Observational Scale. The child failed the Checklist for Autism in Toddlers at 18 months and met the criteria for Asperger syndrome at 26 months. This single case is consistent with the hypersystemizing, assortative mating theory of autism. This theory requires further testing with large samples. This study also demonstrates that Asperger syndrome can be diagnosed by age 26 months. The aim of study 2 was to test if dyadic eye contact in infancy is intact in a child later diagnosed with Asperger syndrome. The same child's eye contact was measured at three time points (3, 6, and 9 months) over her first year of life and compared with that of age-matched controls. Although the child had low rates of eye contact at 6 months, it was within the normal range at all three points in the first year of life. We conclude that low levels of eye contact are not predictive of later development of Asperger syndrome.

    Full Text Available Central corneal thickness (CCT, one of the most highly heritable human traits (h(2 typically>0.9, is important for the diagnosis of glaucoma and a potential risk factor for glaucoma susceptibility. We conducted genome-wide association studies in five cohorts from Australia and the United Kingdom (total N = 5058. Three cohorts were based on individually genotyped twin collections, with the remaining two cohorts genotyped on pooled samples from singletons with extreme trait values. The pooled sample findings were validated by individual genotyping the pooled samples together with additional samples also within extreme quantiles. We describe methods for efficient combined analysis of the results from these different study designs. We have identified and replicated quantitative trait loci on chromosomes 13 and 16 for association with CCT. The locus on chromosome 13 (nearest gene FOXO1 had an overall meta-analysis p-value for all the individually genotyped samples of 4.6x10(-10. The locus on chromosome 16 was associated with CCT with p = 8.95x10(-11. The nearest gene to the associated chromosome 16 SNPs was ZNF469, a locus recently implicated in Brittle Cornea Syndrome (BCS, a very rare disorder characterized by abnormal thin corneas. Our findings suggest that in addition to rare variants in ZNF469 underlying CCT variation in BCS patients, more common variants near this gene may contribute to CCT variation in the general population.

    Spasticity is a common, serious symptom after stroke. Extracorporeal shock wave therapy (ESWT) has been suggested for the treatment of muscle spasticity. To investigate the effects of ESWT on post stroke wrist flexor spasticity. Fifteen patients with poststroke wrist flexor spasticity (12 male and 3 female with a mean age of 54 years) were enrolled. Patients received 1 sham ESWT followed by 1 active ESWT 1 week later. The outcome measures were the Modified Modified Ashworth Scale (MMAS), the Hmax/Mmax ratio, and the Brunnstrom motor recovery stage. The sham ESWT had not effects on the outcome measures. After active ESW, the MMAS scores of spasticity and the Hmax/Mmax ratio improved. The improvements were maintained 5 weeks after active ESWT. No significant improvements were observed for the motor recovery after sham or active ESWT. In adult patients after stroke, a single session of active ESWT resulted in significant improvement in the wrist flexor spasticity and alpha motor neuron excitability.

    Social difficulties and problems related to eating behaviour are common features of both anorexia nervosa (AN) and bulimia nervosa (BN). The aim of this study was to examine the impact of intranasal oxytocin on consummatory behaviour and emotional recognition in patients with AN and BN in comparison to healthy controls. A total of 102 women, including 35 patients with anorexia nervosa (AN), 34 patients with bulimia nervosa (BN), and 33 healthy university students of comparable age and intelligence, participated in a double-blind, single dose placebo-controlled cross-over study. A single dose of intranasal administration of oxytocin (40 IU) (or a placebo) was followed by an emotional recognition task and an apple juice drink. Food intake was then recorded for 24 hours post-test. Oxytocin produced no significant change in appetite in the acute or 24 hours free living settings in healthy controls, whereas there was a decrease in calorie consumption over 24 hours in patients with BN. Oxytocin produced a small increase in emotion recognition sensitivity in healthy controls and in patients with BN, In patients with AN, oxytocin had no effect on emotion recognition sensitivity or on consummatory behaviour. The impact of oxytocin on appetite and social cognition varied between people with AN and BN. A single dose of intranasal oxytocin decreased caloric intake over 24 hours in people with BN. People with BN showed enhanced emotional sensitivity under oxytocin condition similar to healthy controls. Those effects of oxytocin were not found in patients with AN.

    Cortical blindness refers to a visual loss induced by a bilateral occipital lesion. The very strong cooperation between psychophysics, cognitive psychology, neurophysiology and neuropsychology these latter twenty years as well as recent progress in cerebral imagery have led to a better understanding of neurovisual deficits, such as cortical blindness. It thus becomes possible now to propose an earlier diagnosis of cortical blindness as well as new perspectives for rehabilitation in children as well as in adults. On the other hand, studying complex neurovisual deficits, such as cortical blindness is a way to infer normal functioning of the visual system. Copyright © 2013 Elsevier Masson SAS.

    Full Text Available BACKGROUND: Schistosomiasis and opisthorchiasis are of public health importance in Southeast Asia. Praziquantel (PZQ is the drug of choice for morbidity control but few dose comparisons have been made. METHODOLOGY: Ninety-three schoolchildren were enrolled in an area of Lao PDR where Schistosoma mekongi and Opisthorchis viverrini coexist for a PZQ dose-comparison trial. Prevalence and intensity of infections were determined by a rigorous diagnostic effort (3 stool specimens, each examined with triplicate Kato-Katz before and 28-30 days after treatment. Ninety children with full baseline data were randomized to receive PZQ: the 40 mg/kg standard single dose (n = 45 or a 75 mg/kg total dose (50 mg/kg+25 mg/kg, 4 hours apart; n = 45. Adverse events were assessed at 3 and 24 hours posttreatment. PRINCIPAL FINDINGS: Baseline infection prevalence of S. mekongi and O. viverrini were 87.8% and 98.9%, respectively. S. mekongi cure rates were 75.0% (95% confidence interval (CI: 56.6-88.5% and 80.8% (95% CI: 60.6-93.4% for 40 mg/kg and 75 mg/kg PZQ, respectively (P = 0.60. O. viverrini cure rates were significantly different at 71.4% (95% CI: 53.4-84.4% and 96.6% (95% CI: not defined, respectively (P = 0.009. Egg reduction rates (ERRs against O. viverrini were very high for both doses (>99%, but slightly lower for S. mekongi at 40 mg/kg (96.4% vs. 98.1% and not influenced by increasing diagnostic effort. O. viverrini cure rates would have been overestimated and no statistical difference between doses found if efficacy was based on a minimum sampling effort (single Kato-Katz before and after treatment. Adverse events were common (96%, mainly mild with no significant differences between the two treatment groups. CONCLUSIONS/SIGNIFICANCE: Cure rate from the 75 mg/kg PZQ dose was more efficacious than 40 mg/kg against O. viverrini but not against S. mekongi infections, while ERRs were similar for both doses.

    Full Text Available Abstract Background Breathlessness in advanced disease causes significant distress to patients and carers and presents management challenges to health care professionals. The Breathlessness Intervention Service (BIS seeks to improve the care of breathless patients with advanced disease (regardless of cause through the use of evidence-based practice and working with other healthcare providers. BIS delivers a complex intervention (of non-pharmacological and pharmacological treatments via a multi-professional team. BIS is being continuously developed and its impact evaluated using the MRC's framework for complex interventions (PreClinical, Phase I and Phase II completed. This paper presents the protocol for Phase III. Methods/Design Phase III comprises a pragmatic, fast-track, single-blind randomised controlled trial of BIS versus standard care. Due to differing disease trajectories, the service uses two broad service models: one for patients with malignant disease (intervention delivered over two weeks and one for patients with non-malignant disease (intervention delivered over four weeks. The Phase III trial therefore consists of two sub-protocols: one for patients with malignant conditions (four week protocol and one for patients with non-malignant conditions (eight week protocol. Mixed method interviews are conducted with patients and their lay carers at three to five measurement points depending on randomisation and sub-protocol. Qualitative interviews are conducted with referring and non-referring health care professionals (malignant disease protocol only. The primary outcome measure is 'patient distress due to breathlessness' measured on a numerical rating scale (0-10. The trial includes economic evaluation. Analysis will be on an intention to treat basis. Discussion This is the first evaluation of a breathlessness intervention for advanced disease to have followed the MRC framework and one of the first palliative care trials to use fast

    To compare the radiographic bone changes, clinical parameters and aesthetic outcomes of immediately provisionalised and conventionally restored implants at 12- and 24-months post-implant placement. In 24 patients, 24 bone level implants with a hydrophilic (SLActive) surface were placed in healed sites and they were either immediately provisionalised with a non-occluding temporary crown (test group) or left without a crown (control group). In both groups, the definitive restoration was placed 16 weeks after implant placement. Clinical and radiographic parameters were calculated at 12- and 24-months post-implant placement, together with implant success/survival rates according to three different sets of criteria. The aesthetic outcome was evaluated through the Papilla Fill Index and the Pink Aesthetic Score. The mean marginal bone loss at 1 year was -0.73 mm (SD 0.83 mm) in the test group and -0.22 mm (SD 0.46 mm) in the control group (p > .05). Whilst 100% survival rate and positive aesthetic outcomes were recorded in both groups, three patients of the test group did not fulfil all success criteria. Immediate provisionalisation may represent a viable option for the replacement of single missing teeth, with radiographic, clinical and aesthetic results comparable to those of conventionally loaded implants at 2 years of follow-up. © 2017 John Wiley & Sons A/S.

  3. A Single Residue Mutation in the Gαq Subunit of the G Protein Complex Causes Blindness in Drosophila

    2018-01-01

    Full Text Available Heterotrimeric G proteins play central roles in many signaling pathways, including the phototransduction cascade in animals. However, the degree of involvement of the G protein subunit Gαq is not clear since animals with previously reported strong loss-of-function mutations remain responsive to light stimuli. We recovered a new allele of Gαq in Drosophila that abolishes light response in a conventional electroretinogram assay, and reduces sensitivity in whole-cell recordings of dissociated cells by at least five orders of magnitude. In addition, mutant eyes demonstrate a rapid rate of degeneration in the presence of light. Our new allele is likely the strongest hypomorph described to date. Interestingly, the mutant protein is produced in the eyes but carries a single amino acid change of a conserved hydrophobic residue that has been assigned to the interface of interaction between Gαq and its downstream effector, PLC. Our study has thus uncovered possibly the first point mutation that specifically affects this interaction in vivo.

    Depression is common after acute coronary syndrome (ACS) and has adverse effects on prognosis. There are few evidence-based interventions for treating depression in ACS. This study investigated the efficacy and safety of escitalopram in treating depressive disorders identified 2-14 weeks after a confirmed ACS episode. A total of 217 patients with DSM-IV depressive disorders (121 major and 96 minor) and ACS were randomly assigned to receive escitalopram in flexible doses of 5-20 mg/d (n = 108) or placebo (n = 109) for 24 weeks. The study was conducted from 2007 to 2013. The primary outcome measure was the Hamilton Depression Rating Scale (HDRS). Secondary outcome measures included the Montgomery-Asberg Depression Rating Scale (MADRS), Beck Depression Inventory (BDI), Clinical Global Impressions-Severity of Illness scale (CGI-S), Social and Occupational Functioning Assessment Scale (SOFAS), and World Health Organization Disability Assessment Schedule-12. Cardiovascular safety outcomes included echocardiography, electrocardiography, laboratory test, body weight, and blood pressure results. Escitalopram was superior to placebo in reducing HDRS scores (mean difference = 2.3, P = .016, effect size = 0.38). Escitalopram was also superior to placebo in decreasing depressive symptoms evaluated by the MADRS, BDI, and CGI-S and in improving SOFAS functioning level. Escitalopram was not associated with any harmful changes in cardiovascular safety measures. Dizziness was significantly more frequently reported in the escitalopram group (P = .018), but there were no significant differences in any other adverse events. These results indicate that escitalopram has clinically meaningful antidepressant effects with no evidence of reduced cardiovascular safety in depressive disorder following ACS.

    The exact etiology of irritable bowel syndrome (IBS) remains unclear. Curative treatment is not available and current treatment modalities are mainly directed against the predominant symptoms. There are a few studies reporting the beneficial effects of transcutaneous electrical stimulation in patients with chronic constipation, gastroparesis, and functional dyspepsia. To investigate whether transcutaneous electrical stimulation is an effective procedure in IBS patients. IBS patients were randomly placed in vacuum interferential current (IFC) and placebo groups. Both treatments consisted of 12 sessions administered over 4 weeks. Symptoms due to IBS were documented via questionnaires, including the IBS Global Assessment of Improvement Scale, numeric rating scales, visual analogue scale, and IBS Quality of Life Scale at the beginning of, end of, and 1 month after the treatment. Patients in the therapy (29 cases) and placebo (29 cases) groups were homogeneous with respect to demographic data and gastrointestinal system symptoms. When compared to the beginning scores, severity of abdominal discomfort, bloating, and abdominal distension and rumbling improved significantly in either interference or placebo groups at both the end of treatment and 1 month after treatment. In the IFC group, severity of symptoms continued to decrease significantly at 1 month after treatment when compared to scores at just the end of treatment, whereas in the placebo group severity of these symptoms did not change significantly on numeric severity scales. Also, the visual analogue scale of the first month after treatment continued to decrease significantly when compared to the level at the end of treatment in the IFC group. Total quality score increased significantly in the IFC group. Vacuum IFC therapy can significantly improve symptoms and quality of life in patients with IBS. It may represent a novel treatment modality for drug-refractory IBS patients. Copyright © 2012 S. Karger AG, Basel.

    Treacher Collins syndrome (TCS) is a rare craniofacial disorder characterized by facial anomalies and ear defects. TCS is caused by mutations in the TCOF1 gene and follows autosomal dominant inheritance. Recently, mutations in the POLR1D and POLR1C genes have also been identified to cause TCS. However, in a subset of patients no causative mutation could be found yet. Inter- and intrafamilial phenotypic variability is high as is the variety of mainly family-specific mutations identified throughout TCOF1. No obvious correlation between pheno- and genotype could be observed. The majority of described point mutations, small insertions and deletions comprising only a few nucleotides within TCOF1 lead to a premature termination codon. We investigated a cohort of 112 patients with a tentative clinical diagnosis of TCS by multiplex ligation-dependent probe amplification (MLPA) to search for larger deletions not detectable with other methods used. All patients were selected after negative screening for mutations in TCOF1, POLR1D and POLR1C. In 1 patient with an unequivocal clinical diagnosis of TCS, we identified a 3.367 kb deletion. This deletion abolishes exon 3 and is the first described single exon deletion within TCOF1. On RNA level we observed loss of this exon which supposedly leads to haploinsufficiency of TREACLE, the nucleolar phosphoprotein encoded by TCOF1.

    2018-01-01

    It may be possible to use attention-based exercise to decrease demands associated with walking in Parkinson's disease (PD), and thus improve dual task walking ability. For example, an external focus of attention (focusing on the effect of an action on the environment) may recruit automatic control processes degenerated in PD, whereas an internal focus (limb movement) may recruit conscious (nonautomatic) control processes. Thus, we aimed to investigate how externally and internally focused exercise influences dual task walking and symptom severity in PD. Forty-seven participants with PD were randomized to either an Externally (n = 24) or Internally (n = 23) focused group and completed 33 one-hour attention-based exercise sessions over 11 weeks. In addition, 16 participants were part of a control group. Before, after, and 8 weeks following the program (pre/post/washout), gait patterns were measured during single and dual task walking (digit-monitoring task, ie, walking while counting numbers announced by an audio-track), and symptom severity (UPDRS-III) was assessed ON and OFF dopamine replacement. Pairwise comparisons (95% confidence intervals [CIs]) and repeated-measures analyses of variance were conducted. Pre to post: Dual task step time decreased in the external group (Δ = 0.02 seconds, CI 0.01-0.04). Dual task step length (Δ = 2.3 cm, CI 0.86-3.75) and velocity (Δ = 4.5 cm/s, CI 0.59-8.48) decreased (became worse) in the internal group. UPDRS-III scores (ON and OFF) decreased (improved) in only the External group. Pre to washout: Dual task step time ( P = .005) and percentage in double support ( P = .014) significantly decreased (improved) in both exercise groups, although only the internal group increased error on the secondary counting task (ie, more errors monitoring numbers). UPDRS-III scores in both exercise groups significantly decreased ( P = .001). Since dual task walking improvements were found immediately, and 8 weeks after the cessation of an

    Full Text Available Control of onchocerciasis as a public health problem in Africa relies on annual mass ivermectin distribution. New tools are needed to achieve elimination of infection. This study determined in a small number of Onchocerca volvulus infected individuals whether moxidectin, a veterinary anthelminthic, is safe enough to administer it in a future large study to further characterize moxidectin's safety and efficacy. Effects on the parasite were also assessed.Men and women from a forest area in South-eastern Ghana without ivermectin mass distribution received a single oral dose of 2 mg (N = 44, 4 mg (N = 45 or 8 mg (N = 38 moxidectin or 150 µg/kg ivermectin (N = 45 with 18 months follow up. All ivermectin and 97%-100% of moxidectin treated participants had Mazzotti reactions. Statistically significantly higher percentages of participants treated with 8 mg moxidectin than participants treated with ivermectin experienced pruritus (87% vs. 56%, rash (63% vs. 42%, increased pulse rate (61% vs. 36% and decreased mean arterial pressure upon 2 minutes standing still after ≥5 minutes supine relative to pre-treatment (61% vs. 27%. These reactions resolved without treatment. In the 8 mg moxidectin and ivermectin arms, the mean±SD number of microfilariae/mg skin were 22.9±21.1 and 21.2±16.4 pre-treatment and 0.0±0.0 and 1.1±4.2 at nadir reached 1 and 3 months after treatment, respectively. At 6 months, values were 0.0±0.0 and 1.6±4.5, at 12 months 0.4±0.9 and 3.4±4.4 and at 18 months 1.8±3.3 and 4.0±4.8, respectively, in the 8 mg moxidectin and ivermectin arm. The reduction from pre-treatment values was significantly higher after 8 mg moxidectin than after ivermectin treatment throughout follow up (p<0.01.The 8 mg dose of moxidectin was safe enough to initiate the large study. Provided its results confirm those from this study, availability of moxidectin to control programmes could help them achieve onchocerciasis elimination

    To develop an objective method of nailfold capillaroscopy (NFC), applicable to a wide age range of paediatric patients. To compare the morphological characteristics of the nailfold capillaries in different rheumatology patient groups and controls. A colour digital video camera attached to a stereomicroscope was used to capture nailfold capillary images. Computerised image processing was used to analyse and store data. Subsequent quantitative and qualitative morphological analysis was performed in the following paediatric patient and control groups: 18 children with connective tissue diseases (CTD: juvenile dermatomyositis, systemic sclerosis, and undifferentiated connective tissue disease), eight with systemic lupus erythematosus, nine with primary Raynaud's disease, three with primary vasculitis, 15 with juvenile idiopathic arthritis, 17 healthy children and 20 healthy adults. Images were analysed by a single assessor who was unaware of the patient details. The NFC technique was simple to perform and gave reproducible results, although some intra- and intersubject variation was noted. Capillary density and width was age related, with younger children having fewer and wider capillaries than older children and adults. Linear capillary density was significantly higher in healthy adults (mean (SD) 8.6 (1.6) capillaries/mm) compared with healthy children (HC 6.9 (0.9) capillaries/mm). The group with CTD had the most abnormal findings, with lower linear density (4.9 (1.7) capillaries/mm) and increased capillary loop width (10.7 (7.3) mm) compared with HC (3.5 (1.7) mm). In addition, 11/18 (61%) patients in the CTD group had more than two definitely abnormal capillaries in at least two nailfolds, an abnormality not seen in other subjects. Two qualitative measures, the degree of avascularity and general disarrangement of capillary pattern, were more commonly observed in the CTD group than in HC. The proportion of tortuous capillaries did not differ significantly between

    Prevalence, clinicopathological features, and outcome of childhood idiopathic steroid-resistant nephrotic syndrome (ISRNS) vary in different countries. We report on these parameters in a single center in Khartoum. We retrospectively reviewed all the records of children with idiopathic nephrotic syndrome (INS) followed up in the pediatric renal unit, Soba Hospital, Khartoum between 2001 and 2012. ISRNS was defined as no remission within four weeks of daily prednisolone at a dose of 60 mg/m2. In 430 children with INS 130 (28%) had SRNS with a mean age of 7.7 ± 4.12 years. Males were 78 (60%). At presentation, hematuria was recorded in 57%, hypertension was recorded in 48%, and renal impairment in 15%. Histopathology showed focal segmental glomerulosclerosis in 40.8%, mesangioproliferative glomerulonephritis (22.3%), mesangiocapillary glomerulonephritis (16.9%), minimal change disease (MCD) (16.2%), and membranous glomerulonephritis (3.8%). Therapy included cyclosporine in 38.5%, additional therapy with cyclophosphamide, mycophenolate mofetil or tacrolimus in 20.8%, and steroids ± diuretics ± angiotensin converting enzyme (ACE) inhibitors in 40.7%. After 3.64 ± 2.84 years, 26.8% had complete remission (CR), 18.6% partial remission (PR), 26.8% were unremitting, 21.5% had chronic kidney disease (CKD), 1.6% died, and 4.6% were lost to follow-up. Non-MCD cases had significantly lower CR and higher CKD rates than MCD (P = 0.047 and 0.041, respectively). Cyclosporine ± additional therapy was significantly associated with higher rate of CR than steroids ± ACE inhibitors ± diuretics (P = 0.001), but the prevalence of CKD between the two groups was not significantly different (P = 0.604). Impaired renal function and hypertension at presentation were risk factors for CKD (P = 0.001 and 0.001, respectively). In Sudanese children with ISRNS, non-MCD lesions were the most common lesions. This pattern in addition to the lack of adequate therapy may explain the relatively

    Peutz-Jeghers syndrome (PJS) in children may present with anaemia, intussusception, or obstruction from an early age and surgery is common. Prophylactic polypectomy may reduce subsequent complications. Traditional barium enterography (BE) has poor sensitivity and requires significant radiation. We compared the performance of capsule endoscopy (CE) with BE in children with PJS. Children with PJS (ages 6.0-16.5 years) were prospectively recruited and underwent BE followed by CE, each reported by expert reviewers blinded to the alternate modality. Number of "significant" (>10 mm) and total number of polyps were recorded. Child preference was assessed using a visual analogue questionnaire. Definitive findings were assessed at laparotomy or enteroscopy, when performed. There was no significant difference for >10 mm polyp detection. Six polyps were found in 3 children by both modalities: 3 polyps in 2 children at CE, 3 polyps in 1 child at BE (P=0.50). Re-review of 1 CE identified 3 polyps that were missed in 1 child at initial reading. Significantly more polyps were identified by CE than BE: 61 vs 6 (P=0.02). CE was significantly more comfortable than BE (median score CE 76 [interquartile range 69-87] vs BE 37 [interquartile range 31-68], P=0.03) and was the preferred investigation in 90% (P=0.02). CE is a feasible, safe, and sensitive test for small bowel polyp surveillance in children with PJS. It is significantly more comfortable than BE and is the preferred test of most children for future surveillance. There is a learning curve for reporting CE studies in PJS and appropriate training is essential.

    To compare the effectiveness of ischemic compression (IC) directly to the vastus medialis obliquus (VMO) versus lumbopelvic manipulation (LPM) in improving pain, functional status and sensitivity to mechanical stimulation of the VMO trigger point in patients with patellofemoral pain syndrome (PFPS). 40 patients with unilateral PFPS aged 20-30 years were selected randomly among patients with unilateral PFPS referred to physical therapy clinics of Shiraz University of Medical Sciences in Shiraz, Iran, between March 2014 and July 2014. 30 young adults participated. Participants were blinded to treatment allocation, and 15 patients were allocated to either IC or LPM. Patients in both groups were treated in three sessions per week. IC consisted of three sets of continuous pressure applied for on the myofascial trigger point (MTrP) of VMO. LPM consisted of supine rotational glide manipulation of the ipsilateral lumbopelvic region of the involved knee. Numeric pain rating scale (VAS) for pain intensity, Kujala questionnaire for functional status, and pressure pain threshold (PPT) for sensitivity to mechanical stimulation. All three were recorded before treatment, 1 week, 1 month and 3 months after the last session. Both groups showed significant improvement (p < 0.05, 95% confidence interval) in pain, functional status and PPT values. However, the IC group showed greater improvements, and outcome measures remained significantly better than in the LPM group during post-intervention follow-up. Both groups showed improvements throughout the study and follow-up period. However, the IC showed better short-term and long-term effectiveness than LPM for treating PFPS.

    Full Text Available Shugan Jianpi Zhixie therapy (SJZT has been widely used to treat diarrhea-predominant irritable bowel syndrome (IBS-D, but the results are still controversial. A meta-analysis of randomized, double-blind, placebo-controlled trials was performed to assess the efficacy and tolerability of SJZT for IBS-D.The MEDLINE, EMBASE, Cochrane Library, the China National Knowledge Infrastructure database, the Chinese Biomedical Literature database and the Wanfang database were searched up to June 2014 with no language restrictions. Summary estimates, including 95% confidence intervals (CI, were calculated for global symptom improvement, abdominal pain improvement, and Symptom Severity Scale (BSS score.Seven trials (N=954 were included. The overall risk of bias assessment was low. SJZT showed significant improvement for global symptom compared to placebo (RR 1.61; 95% CI 1.24, 2.10; P =0.0004; therapeutic gain = 33.0%; number needed to treat (NNT = 3.0. SJZT was significantly more likely to reduce overall BSS score (SMD -0.67; 95% CI -0.94, -0.40; P < 0.00001 and improve abdominal pain (RR 4.34; 95% CI 2.64, 7.14; P < 0.00001 than placebo. The adverse events of SJZT were no different from those of placebo.This meta-analysis suggests that SJZT is an effective and safe therapy option for patients with IBS-D. However, due to the high clinical heterogeneity and small sample size of the included trials, further standardized preparation, large-scale and rigorously designed trials are needed.

    Full Text Available Birt-Hogg-Dubé syndrome (BHD is a rare autosomal dominant disorder characterised by the occurrence of benign, mostly facial, skin tumours called fibrofolliculomas, multiple lung cysts, spontaneous pneumothorax and an increased renal cancer risk. Current treatments for fibrofolliculomas have high rates of recurrence and carry a risk of complications. It would be desirable to have a treatment that could prevent fibrofolliculomas from growing. Animal models of BHD have previously shown deregulation of mammalian target of rapamycin (mTOR. Topical use of the mTOR inhibitor rapamycin is an effective treatment for the skin tumours (angiofibromas in tuberous sclerosis complex, which is also characterised by mTOR deregulation. In this study we aimed to determine if topical rapamycin is also an effective treatment for fibrofolliculomas in BHD.We performed a double blinded, randomised, facial left-right controlled trial of topical rapamycin 0.1% versus placebo in 19 BHD patients. Trial duration was 6 months. The primary outcome was cosmetic improvement as measured by doctors and patients. Changes in fibrofolliculoma number and size were also measured, as was occurrence of side effects.No change in cosmetic status of fibrofolliculomas was reported in the majority of cases for the rapamycin treated (79% by doctors, 53% by patients as well as the placebo treated facial sides (both 74%. No significant differences between rapamycin and placebo treated facial halves were observed (p = 1.000 for doctors opinion, p = 0.344 for patients opinion. No significant difference in fibrofolliculoma number or change in size of the fibrofolliculomas was seen after 6 months. Side effects occurred more often after rapamycin treatment (68% of patients than after placebo (58% of patients; p = 0.625. A burning sensation, erythema, itching and dryness were most frequently reported.This study provides no evidence that treatment of fibrofolliculomas with topical

    Bacillus coagulans MTCC 5856 has been marketed as a dietary ingredient, but its efficacy in diarrhea predominant irritable bowel syndrome (IBS) condition has not been clinically elucidated till date. Thus, a double blind placebo controlled multi-centered trial was planned to evaluate the safety and efficacy of B. coagulans MTCC 5856 in diarrhea predominant IBS patients. Thirty six newly diagnosed diarrhea predominant IBS patients were enrolled in three clinical centres. Along with standard care of treatment, 18 patients in group one received placebo while in group two 18 patients received B. coagulans MTCC 5856 tablet containing 2 × 10(9) cfu/day as active for 90 days. Clinical symptoms of IBS were considered as primary end point measures and were evaluated through questionnaires. The visual analog scale (VAS) was used for abdominal pain. Physician's global assessment and IBS quality of life were considered as secondary efficacy measures and were monitored through questionnaires. Laboratory parameters, anthropometric and vital signs were within the normal clinical range during the 90 days of supplementation in placebo and B. coagulans MTCC 5856 group. There was a significant decrease in the clinical symptoms like bloating, vomiting, diarrhea, abdominal pain and stool frequency in a patient group receiving B. coagulans MTCC 5856 when compared to placebo group (p coagulans MTCC 5856 when compared to placebo group. The study concluded that the B. coagulans MTCC 5856 at a dose of 2 × 10(9) cfu/day along with standard care of treatment was found to be safe and effective in diarrhea predominant IBS patients for 90 days of supplementation. Hence, B. coagulans MTCC 5856 could be a potential agent in the management of diarrhea predominant IBS patients.

    To determine the effects of scapular mobilization on function, pain, range of motion, and satisfaction in patients with subacromial impingement syndrome (SAIS). Randomized, double-blind, placebo-controlled clinical trial. University hospital clinics in Turkey. 66 participants (mean ± SD age 52.06 ± 3.71 y) with SAIS. Participants were randomized into 3 groups: scapular mobilization, sham scapular mobilization, and supervised exercise. Before the interventions transcutaneous electrical stimulation and hot pack were applied to all groups. Total intervention duration for all groups was 3 wk with a total of 9 treatment sessions. Shoulder function and pain intensity were primary outcome measures; range of motion and participant satisfaction were secondary outcome measures. Shoulder function was assessed with the short form of the Disabilities of the Arm, Shoulder and Hand Questionnaire (DASH). A visual analog scale was used to evaluate pain severity. Active range of motion was measured with a universal goniometer. A 7-point Likert scale was used to evaluate satisfaction. Outcome measurements were performed at baseline, before visits 5 and 10, 4 wk after visit 9, and 8 wk after visit 9. There was no group difference for DASH score (P = .75), pain at rest (P = .41), pain with activity (P = .45), pain at night (P = .74), and shoulder flexion (P = .65), external rotation (P = .63), and internal rotation (P = .19). There was a significant increase in shoulder motion and function and a significant decrease in pain across time when all groups were combined (P .05). There was not a significant advantage of scapular mobilization for shoulder function, pain, range of motion, and satisfaction compared with sham or supervised-exercise groups in patients with SAIS.

    Observational studies and anecdotal reports suggest that sertraline, a selective serotonin reuptake inhibitor, may improve language development in young children with fragile X syndrome (FXS). The authors evaluated the efficacy of 6 months of treatment with low-dose sertraline in a randomized, double-blind, placebo-controlled trial in 52 children with FXS aged 2 to 6 years. Eighty-one subjects were screened for eligibility, and 57 were randomized to sertraline (27) or placebo (30). Two subjects from the sertraline arm and 3 from the placebo arm discontinued. Intent-to-treat analysis showed no difference from placebo on the primary outcomes: the Mullen Scales of Early Learning (MSEL) expressive language (EL) age equivalent and Clinical Global Impression Scale-Improvement. However, analyses of secondary measures showed significant improvements, particularly in motor and visual perceptual abilities and social participation. Sertraline was well tolerated, with no difference in side effects between sertraline and placebo groups. No serious adverse events occurred. This randomized controlled trial of 6 months of sertraline treatment showed no primary benefit with respect to early EL development and global clinical improvement. However, in secondary exploratory analyses, there were significant improvements seen on motor and visual perceptual subtests, the cognitive T score sum on the MSEL, and on one measure of social participation on the Sensory Processing Measure-Preschool. Furthermore, post hoc analysis found significant improvement in early EL development as measured by the MSEL among children with autism spectrum disorder on sertraline. Treatment appears safe for this 6-month period in young children with FXS, but the authors do not know the long-term side effects of this treatment. These results warrant further studies of sertraline in young children with FXS using refined outcome measures as well as longer term follow-up studies to address long-term side effects of

    Increase in prevalence of obesity and type 2 diabetes which are of the main risk factors of metabolic syndrome, is not only the result of changes in genetic, diet or physical activity, but also an imbalance of micro flora may play an important role. Therefore, alteration of micro flora using pre/probiotic is considered as a new strategy for treatment of metabolic disorders. The current study is a triple blind randomized controlled trial. 46 patients from both sexes, who fulfilled inclusion criteria, randomly categorized into intervention or placebo group. The intervention and placebo groups consumed 2 probiotic capsules or 2 placebo capsules during 3 months, respectively. Both groups received a weight loss diet, according to their adjusted ideal body weight. Anthropometric, body composition, blood pressure and nutritional measurements were done in the beginning, at 6th week, and at the end of the study. T-test and paired-t test were used for statistical analysis. 40 patients completed the study. BMI, WC, HC, fat mass, lean mass and blood pressure were reduced in all participants (p< 0.05). Systolic blood pressure in symbiotic group was less than placebo group, significantly (p< 0.05). The trend of weight loss in symbiotic group continued at least for 12 weeks while it was stopped at week 6 in placebo group. Symbiotic supplement with the weight loss diet had synergistic effects on improvement in systolic blood pressure and anthropometric measurements. Based on our findings, symbiotic can postpone plateau phase of weight loss and it may prevent resistance to further weight loss.

    The primary treatment outcomes of a phase 2, randomized, double‐blind, pilot study evaluating safety, physiological, and pharmacological effects of elosulfase alfa in patients with Morquio A syndrome are herewith presented. Patients aged ≥7 years and able to walk ≥200 m in the 6‐min walk test (6MWT) were randomized to elosulfase alfa 2.0 or 4.0 mg/kg/week for 27 weeks. The primary objective was to evaluate the safety of both doses. Secondary objectives were to evaluate effects on endurance (6MWT and 3‐min stair climb test [3MSCT]), exercise capacity (cardio‐pulmonary exercise test [CPET]), respiratory function, muscle strength, cardiac function, pain, and urine keratan sulfate (uKS) levels, and to determine pharmacokinetic parameters. Twenty‐five patients were enrolled (15 randomized to 2.0 mg/kg/week and 10 to 4.0 mg/kg/week). No new or unexpected safety signals were observed. After 24 weeks, there were no improvements versus baseline in the 6MWT, yet numerical improvements were seen in the 3MSCT with 4.0 mg/kg/week. uKS and pharmacokinetic data suggested no linear relationship over the 2.0–4.0 mg/kg dose range. Overall, an abnormal exercise capacity (evaluated in 10 and 5 patients in the 2.0 and 4.0 mg/kg/week groups, respectively), impaired muscle strength, and considerable pain were observed at baseline, and there were trends towards improvements in all domains after treatment. In conclusion, preliminary data of this small study in a Morquio A population with relatively good endurance confirmed the acceptable safety profile of elosulfase alfa and showed a trend of increased exercise capacity and muscle strength and decreased pain. © 2015 The Authors.

    To evaluate the effects of pulsed electromagnetic field (PEMF) and exercises in reducing pain and improving function and muscle strength in patients with shoulder impingement syndrome (SIS). Double-blind, randomized controlled trial with a 3-month posttreatment follow-up. Outpatient rehabilitation of a public hospital. Patients (N=56) between 40 and 60 years of age, with a diagnosis of SIS, were randomly assigned to receive active PEMF (n=26; mean age, 50.1y) or placebo PEMF (n=30; mean age, 50.8y). After 3 weeks of active or placebo PEMF, both groups performed the same program of exercises that focused on shoulder strengthening. A visual analog scale, the University of California/Los Angeles shoulder rating scale, the Constant-Murley shoulder score, and handheld dynamometry for muscle strength were used as outcome measures at baseline (pretreatment), at 3 weeks (after active or placebo PEMF), at 9 weeks (postexercise), and at 3 months posttreatment. Patients in the active PEMF group had a higher level of function and less pain at all follow-up time frames compared with baseline (Pshoulder dynamometry, the active PEMF group had increased strength for lateral rotation at 9 weeks (Pshoulder strength in the placebo PEMF group (P>.05), as well as no significant differences (P>.05) for all outcome measures. The combination of PEMF and shoulder exercises is effective in improving function and muscle strength and decreasing pain in patients with SIS. However, these results should be carefully interpreted because of the lack of differences between groups. Copyright © 2014 American Congress of Rehabilitation Medicine. Published by Elsevier Inc.

    The role of metformin in the treatment of infertility in women with polycystic ovary syndrome (PCOS) is still controversial. OBJECTIVE AND OUTCOMES: We investigated whether metformin decreases the early miscarriage rate and improves the pregnancy rates (PR) and live-birth rates (LBR) in PCOS. This was a multicenter, randomized (1:1), double-blind, placebo-controlled study. Three hundred twenty women with PCOS and anovulatory infertility were randomized to metformin (n = 160, Diformin; obese women, 1000 mg two times daily; nonobese subjects, 500 mg + 1000 mg daily) or identical doses of placebo (n = 160). After 3 months' treatment, another appropriate infertility treatment was combined if necessary. If pregnancy occurred, metformin/placebo was continued up to the 12th week. Miscarriage rates were low and similar in the two groups (metformin 15.2% vs. placebo 17.9%, P = 0.8). Intent-to-treat analysis showed that metformin significantly improved PR and LBR (vs. placebo) in the whole study population (PR: 53.6 vs. 40.4%, P = 0.006; LBR: 41.9 vs. 28.8%, P = 0.014) and PR in obese women (49.0 vs. 31.4%, P = 0.04), and there was a similar trend in nonobese (PR: 58.6 vs. 47.6%, P = 0.09; LBR: 46.7 vs. 34.5%, P = 0.09) and in obese women with regard to LBR (35.7 vs. 21.9%, P = 0.07). Cox regression analysis showed that metformin plus standard infertility treatment increased the chance of pregnancy 1.6 times (hazard rate 1.6, 95% confidence interval 1.13-2.27). Obese women especially seem to benefit from 3 months' pretreatment with metformin and its combination thereafter with routine ovulation induction in anovulatory infertility.

    POTS (postural tachycardia syndrome) is a chronic form of OI (orthostatic intolerance). Neuropathic POTS is characterized by decreased adrenergic vasoconstriction, whereas hyperadrenergic POTS exhibits increased adrenergic vasoconstriction. We hypothesized that midodrine, an α1-adrenergic receptor agonist, would increase CVR (calf vascular resistance), decrease C(v) (calf venous capacitance) and decrease orthostatic tachycardia in neuropathic POTS, but not alter haemodynamics in hyperadrenergic POTS. A total of 20 POTS patients (12 neuropathic and eight hyperadrenergic), ages 12-20 years, participated in this randomized placebo-controlled double-blind cross-over study. Of these subjects, 15 were female. POTS subjects received 2 weeks of treatment with midodrine or placebo, with increased dosing from 2.5 to 10 mg three times daily. Following a 7-day drug-washout period, subjects received the cross-over treatment. HR (heart rate), MAP (mean arterial pressure), Q(calf) (calf blood flow) and CVR were measured supine and during 35° HUT (head-up tilt). C(v) was measured supine. In neuropathic POTS, midodrine decreased supine HR, Q(calf) and C(v), while increasing MAP and CVR compared with placebo. During HUT, in neuropathic POTS, midodrine decreased HR, Q(calf) and C(v), while increasing MAP and CVR. In hyperadrenergic POTS, placebo and midodrine both decreased upright HR and increased supine CVR. Placebo also increased supine C(v), compared with midodrine in hyperadrenergic POTS. Therefore midodrine improved postural tachycardia in neuropathic POTS by increasing CVR and decreasing Q(calf) and C(v), whereas these effects were not seen in hyperadrenergic POTS patients who experienced a placebo effect. This suggests that midodrine is probably an effective treatment for neuropathic POTS, but not for hyperadrenergic POTS.

    To measure the association between the menstrual cycle and the frequency of alveolar osteitis (AO). In a study with a single-blind design, patients with bilateral impacted third molar teeth underwent randomized surgical extraction: one tooth during the menstrual period and one during the middle of the cycle. The postoperative examiner was unaware of the menstrual cycle status of the patients. The predictor variable was the timing of the menstrual cycle and was grouped as mid-cycle and menstrual period. The outcome variable was AO, which was measured (without knowledge of the menstrual cycle timing) at 2 to 7 days postoperatively. Other study variables included oral contraceptive (OC) use, smoking status, irrigation used during surgery, extraction difficulty, surgeon experience, number of local anesthetic cartridges used, and patient age. Appropriate bi- and multivariate statistics were computed, and the level of statistical significance was set at P cycle than during the menstrual period inboth the OC users and nonusers (P menstrual period (P > .05). According to the results of the present study, the menstrual cycle could be a determinant risk factor in the frequency of AO. We recommend that elective procedures be performed during the menstrual period in both OC users and nonusers to eliminate the effect of cycle-related hormonal changes on the development of AO.

This was a single-blind randomized controlled study with a 2-arm parallel group design. Eighty-one subjects were randomly assigned to 12 sessions intervention group (CBGT or control group (usual outpatient psychiatric care group and 62 completed the study. The primary outcome was depression measured with Beck Depression Inventory (BDI-II and Hamilton Rating Scale for Depression (HRSD. The secondary outcomes were automatic thoughts measured by automatic thoughts questionnaire (ATQ. Both groups were evaluated at the pretest (before 2 weeks, posttest (after 12 therapy sessions, and short- (3 months, medium- (6 months, and long-term (12 months follow-up. After receiving CBGT, the experimental group had a statistically significant reduction in the BDI-II from 40.30 at baseline to 17.82 points at session eight and to 10.17 points at postintervention (P<0.001. Similar effects were seen on the HRSD. ATQ significantly decreased at the 12th session, 6 months after sessions, and 1 year after the sessions ended (P<0.001. We concluded that CBGT is effective for reducing depression and continued to be effective at 1 year of follow-up.

    Interdisciplinary physical therapy together with pharmacological treatment constitute conservative treatment strategies related to low back pain (LBP). There is still a lack of high quality studies aimed at an objective evaluation of physiotherapeutic procedures according to their effectiveness in LBP. The aim of this study is to carry out a prospective, randomized, single-blinded, and placebocontrolled clinical trial to evaluate the effectiveness of magnetic fields in discopathy-related LBP. A group of 177 patients was assessed for eligibility based on inclusion and exclusion criteria. In the end, 106 patients were randomly assigned into 5 comparative groups: A (n = 23; magnetic therapy: 10 mT, 50 Hz); B (n = 23; magnetic therapy: 5 mT, 50 Hz); C (n = 20; placebo magnetic therapy); D (n = 20; magnetic stimulation: 49.2 μT, 195 Hz); and E (n = 20; placebo magnetic stimulation). All patients were assessed using tests for pain intensity, degree of disability and range of motion. Also, postural stability was assessed using a stabilographic platform. In this study, positive changes in all clinical outcomes were demonstrated in group A (p 0.05). It was determined that the application of magnetic therapy (10 mT, 50 Hz, 20 min) significantly reduces pain symptoms and leads to an improvement of functional ability in patients with LBP.

    At present, aromatherapy is used widely in medical research. This study aimed to investigate the effects of inhalation aromatherapy using lavender essential oil to reduce mental stress and improve the vital signs of patients after coronary artery bypass surgery (CABG). A single-blinded randomized controlled trial was conducted with 60 patients who had undergone CABG in a 2-day intervention that targeted stress reduction. Sixty subjects following coronary artery bypass surgery in two aromatherapy and control groups. The study was conducted in Ekbatan Therapeutic and Educational Center, Hamadan, Iran, in 2013. On the second and third days after surgery, the aromatherapy group patients received two drops of 2% lavender essential oil for 20min and the control group received two drops of distilled water as a placebo. The primary outcome was mental stress, which was measured before and after the intervention using the DASS-21 questionnaire. The secondary outcomes were vital signs, including the heart rate, respiratory rate, and systolic and diastolic blood pressure, which were measured before and after the intervention. The individual characteristics of the aromatherapy and control groups were the same. There were no significant difference in the mean mental stress scores and vital signs of the aromatherapy and control groups on the second or third days after surgery. Inhalation aromatherapy with lavender essential oil had no significant effects on mental stress and vital signs in patients following CABG, except the systolic blood pressure.

    Hemodynamic response to airway stimuli is a common phenomenon and its management is important to reduce the systemic repercussions. The objective of this study is to compare the efficacy of intravenous magnesium sulfate versus lidocaine on this reflex hemodynamics after laryngoscopy and tracheal intubation. This single-center, prospective, double-blind, randomized study evaluated 56 patients ASA 1 or 2, aged 18-65 years, scheduled for elective surgeries under general anesthesia with intubation. The patients were allocated into two groups: Group F received 30mg·kg -1 of magnesium sulphate and Group L, 2mg·kg -1 of lidocaine, continuous infusion, immediately before the anesthetic induction. Blood pressure (BP), heart rate (HR), and bispectral index (BIS) were measured in both groups at six different times related to administration of the study drugs. In both groups there was an increase in HR and BP after laryngoscopy and intubation, compared to baseline. Group M showed statistically significant increase in the values of systolic and diastolic blood pressure after intubation, which was clinically unimportant. There was no difference in the BIS values between groups. Among patients receiving magnesium sulfate, three (12%) had high blood pressure versus only one among those receiving lidocaine (4%), with no statistical difference. Magnesium sulfate and lidocaine have good efficacy and safety for hemodynamic management in laryngoscopy and intubation. Copyright © 2016 Sociedade Brasileira de Anestesiologia.

    Single-blind randomized clinical trial, with a follow-up of 24 weeks. To determine the effects of hyperthermia via localized microwave diathermy on pain and disability in comparison to subacromial corticosteroid injections in patients with rotator cuff tendinopathy. Hyperthermia improves symptoms and function in several painful musculoskeletal disorders. However, the effects of microwave diathermy in rotator cuff tendinopathy have not yet been established. Ninety-two patients with rotator cuff tendinopathy and pain lasting for at least 3 months were recruited from the outpatient clinic of the Department of Orthopaedics and Traumatology, University Hospital, Rome, Italy. Participants were randomly allocated to either local microwave diathermy or subacromial corticosteroids. The primary outcome measure was the short form of the Disabilities of the Arm, Shoulder and Hand Questionnaire (QuickDASH). Secondary outcome measures were the Constant-Murley shoulder outcome score and a visual analog scale for pain assessment. At the end of treatment and at follow-up, both treatment groups experienced improvements in all outcome measures relative to baseline values. Changes over time in QuickDASH, Constant-Murley, and visual analog scale scores were not different between treatment arms. In patients with rotator cuff tendinopathy, the effects of localized microwave diathermy on disability, shoulder function, and pain are equivalent to those elicited by subacromial corticosteroid injections.

    Tacrolimus is a topical calcineurin inhibitor with immunomodulatory, anti-inflammatory, and fungicidal properties that may be beneficial in the treatment of facial seborrheic dermatitis. We sought to compare the efficacy and safety of tacrolimus with standard corticosteroid treatment in adults with facial seborrheic dermatitis in a phase II, single-blind, randomized controlled trial. Adult patients were enrolled in a 12-week study. Subjects were randomized to tacrolimus 0.1% ointment (n = 16) or hydrocortisone 1% ointment (n = 14) applied twice daily to symptomatic regions of the face. The primary efficacy measure was the severity of facial seborrhea at the end of treatment (day 84) as measured by the Seborrhea Area and Severity Index-Face. Secondary efficacy measures included physician and patient assessment of seborrhea, the frequency of medication application, and adverse events. The severity of facial seborrhea was similarly improved in both treatment groups (P = .86). Tacrolimus 0.1% ointment was used on significantly fewer days than 1% hydrocortisone ointment (mean missed doses per patient at first visit: 15.6 vs 7.6, P seborrheic dermatitis. Tacrolimus was generally well tolerated. Copyright © 2011 American Academy of Dermatology, Inc. Published by Mosby, Inc. All rights reserved.

    To investigate the efficacy and safety of the combined therapy with high-frequency transcutaneous electrical nerve stimulation (hf-TENS) and thermotherapy in relieving primary dysmenorrheal pain. In this randomized, single-blind, placebo-controlled study, 115 women with moderate or severe primary dysmenorrhea were assigned to the study or control group at a ratio of 1:1. Subjects in the study group used an integrated hf-TENS/thermotherapy device, whereas control subjects used a sham device. A visual analog scale was used to measure pain intensity. Variables related to pain relief, including reduction rate of dysmenorrheal score, were compared between the groups. The dysmenorrheal score was significantly reduced in the study group compared to the control group following the use of the devices. The duration of pain relief was significantly increased in the study group compared to the control group. There were no differences between the groups in the brief pain inventory scores, numbers of ibuprofen tablets taken orally, and World Health Organization quality of life-BREF scores. No adverse events were observed related to the use of the study device. The combination of hf-TENS and thermotherapy was effective in relieving acute pain in women with moderate or severe primary dysmenorrhea. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    To evaluate the effectiveness of brief motivational interviewing and an educational brochure when delivered in emergency room to reduce alcohol abuse and related problems among adolescents and young adults. A randomized single-blind clinical trial with a three-month follow-up was carried out at three emergency rooms from October 2004 to November 2005; subjects assessed were 16-25 years old treated for alcohol related events up to 6 hours after consumption. Socio-demographic data, quantity, frequency and negative consequences of alcohol consumption, motivation to change habits and future risk perception were evaluated. Statistical analysis was performed on subjects who completed follow-up (completers). ANCOVA model was used to analyze the difference between the intervention groups with statistical significance level α = 5% and confidence interval (CI) of 95%. 186 subjects formed the initial sample, being 175 included and randomized to the educational brochure group (n = 88) or motivational interviewing group (n = 87). Follow-up assessment was performed in 85.2% of the sample. No significant difference between groups was observed. However, significant reductions (p motivational interviewing, educational brochure and nonintervention should be of future interest among Brazilian adolescent populations.

    To investigate whether hippotherapy (when applied by a simulator) improves postural control and balance in children with cerebral palsy. Stratified single-blind randomized controlled trial with an independent assessor. Stratification was made by gross motor function classification system levels, and allocation was concealed. Children between 4 and 18 years old with cerebral palsy. Participants were randomized to an intervention (simulator ON) or control (simulator OFF) group after getting informed consent. Treatment was provided once a week (15 minutes) for 10 weeks. Gross Motor Function Measure (dimension B for balance and the Total Score) and Sitting Assessment Scale were carried out at baseline (prior to randomization), end of intervention and 12 weeks after completing the intervention. Thirty-eight children participated. The groups were balanced at baseline. Sitting balance (measured by dimension B of the Gross Motor Function Measure) improved significantly in the treatment group (effect size = 0.36; 95% CI 0.01-0.71) and the effect size was greater in the severely disabled group (effect size = 0.80; 95% CI 0.13-1.47). The improvements in sitting balance were not maintained over the follow-up period. Changes in the total score of the Gross Motor Function Measure and the Sitting Assessment Scale were not significant. Hippotherapy with a simulator can improve sitting balance in cerebral palsy children who have higher levels of disability. However, this did not lead to a change in the overall function of these children (Gross Motor Function Classification System level V).

    Despite good success rates reported with ultrasound-guided supraclavicular block using 1 or multiple injections, no consensus exists on the best technique to use. We designed this study to test the hypothesis that a double-injection technique would hasten the onset of sensory block. Adult patients undergoing hand, wrist, or elbow surgery were enrolled in this prospective double-blind randomized study. Blocks were performed under ultrasound guidance. In group S (single injection), 30 mL of mepivacaine 1.5% was injected at the junction of the subclavian artery and the first rib. In group D (double injection), 15 mL of the same solution was injected at the site described above, then 15 mL was injected in the most superficial portion of the lateral aspect of the cluster formed by the brachial plexus trunks and divisions. The primary end point was the rate of complete sensory block at 15 mins. Secondary end points were the rates of sensory, motor, and surgical blocks and procedure time. Fifty-one patients were randomized to each group. The rate of complete sensory block was similar at 15 mins (group S: 49% [95% confidence interval, 36%-62%], group D: 53% [95% confidence interval, 40%-66%]; P = 0.80) and at each time interval. The rates of complete motor block and surgical block success were similar between groups. The procedure time was shorter in group S (179 ± 104 vs 275 ± 137 secs; P block.

    To assess the anti-adhesive effect of treatment with hyaluronic acid-carboxymethylcellulose following laparoscopic radical prostatectomy. This was a randomized, controlled, single-blind, parallel-group study using hyaluronic acid-carboxymethylcellulose in patients who underwent laparoscopic radical prostatectomy. Sixty patients were enrolled in the study. All patients were randomly assigned to either the hyaluronic acid-carboxymethylcellulose treatment group (n = 30) or the control group (n = 30). Viscera slide ultrasounds and plain X-rays were obtained at enrollment (V0), postoperative week 12 (V1), and 24 (V2). The primary end point was the difference in the excursion distance in the viscera slide ultrasound between V0 and V2. A total of 50 patients completed this study. The average excursion distance at V2 in the experimental group (n = 25) was significantly longer than in the control group (n = 25, 2.7 ± 1.2 vs. 1.3 ± 1.0 cm, respectively; p hyaluronic acid-carboxymethylcellulose. This randomized study demonstrated that hyaluronic acid-carboxymethylcellulose treatment resulted in a reduction in bowel adhesion to the abdominal wall after laparoscopic pelvic surgery and had good clinical safety.

    To determine whether spa therapy has a beneficial effect on pain and disability in patients with chronic shoulder pain, this single-blind randomised controlled clinical trial included patients with chronic shoulder pain due to miscellaneous conditions attending one of four spa centres as outpatients. Patients were randomised into two groups: spa therapy (18 days of standardised treatment combining thermal therapy together with supervised mobilisation in a thermal pool) and controls (spa therapy delayed for 6 months: `immediate versus delayed treatment' paradigm). All patients continued usual treatments during the 6-month follow-up period. The main endpoint was the mean change in the French-Quick DASH (F-QD) score at 6 months. The effect size of spa therapy was calculated, and the proportion of patients reaching minimal clinically important improvement (MCII) was compared. Secondary endpoints were the mean change in SF-36, treatment use and tolerance. One hundred eighty-six patients were included (94 patients as controls, 92 in the spa group) and analysed by intention to treat. At 6 months, the mean change in the F-QD score was statistically significantly greater among spa therapy patients than controls (- 32.6 versus - 8.15%; p pain, function and quality of life in patients with chronic shoulder pain after 6 months compared with usual care.

    A previous questionnaire study suggests an increased chocolate consumption in Parkinson's disease (PD). The cacao ingredient contains caffeine analogues and biogenic amines, such as β-phenylethylamine, with assumed antiparkinsonian effects. We thus tested the effects of 200 g of chocolate containing 80 % of cacao on UPDRS motor score after 1 and 3 h in 26 subjects with moderate non-fluctuating PD in a mono-center, single-dose, investigator-blinded crossover study using cacao-free white chocolate as placebo comparator. At 1 h after chocolate intake, mean UPDRS motor scores were mildly decreased compared to baseline in both treatments with significant results only for dark chocolate [-1.3 (95 % CI 0.18-2.52, RMANOVA F = 4.783, p = 0.013¸ Bonferroni p = 0.021 for 1 h values)]. A 2 × 2-cross-over analysis revealed no significant differences between both treatments [-0.54 ± 0.47 (95 % CI -1.50 to 0.42), p = 0.258]. Similar results were obtained at 3 h after intake. β-phenylethylamine blood levels were unaltered. Together, chocolate did not show significant improvement over white cacao-free chocolate in PD motor function.

    ProSeal Laryngeal Mask Airway (PLMA) is extensively being used in pediatric anesthesia. To evaluate the efficacy of PLMA as compared to Classic Laryngeal Mask Airway (CLMA) for airway maintenance in pediatric patients. A prospective, randomized, Single-blinded study was conducted in a tertiary care teaching hospital. Sixty ASA I and II children were included. Patients were randomized to either size 2 PLMA or size 2 CLMA groups. Parameters noted were time for insertion, number of attempts, airway sealing pressure, blood pressures (systolic, diastolic, and mean), pulse rate, end-tidal carbon dioxide (EtCO(2)), peripheral oxygen saturation (SpO(2)), and postoperative change in abdominal circumference, and airway trauma. Parametric data were analyzed with the unpaired t-test and non-parametric data were analyzed with the chi-square (χ(2)) test. Unless otherwise stated, data are presented as mean (SD). Significance was taken as P insertion, airway sealing pressure, hemodynamic responses, SpO(2), EtCO(2) and postoperative changes in abdominal circumference. Patients in the PLMA group had longer time of insertion and higher incidence of airway trauma. The PLMA and the CLMA were comparable for hemodynamic and ventilatory parameters and change in abdominal circumference; however, the time taken for insertion and airway trauma was more with PLMA.

    The aim of this randomized double-blind study was to evaluate in healthy adult subjects, with functional magnetic resonance imaging (fMRI), long lasting changes in brain activation patterns following administration of a single, 250 milliseconds pulse emitted with radio-electric asymmetric conveyer (REAC) technology in the Wi-Fi bands. The REAC impulse was not administered during the scan, but after this, according to a protocol that has previously been demonstrated to be effective in improving motor control and postural balance, in healthy subjects and patients. The study was conducted on 33 healthy volunteers, performed with a 1.5 T unit while operating a motor block task involving cyclical and alternating flexion and extension of one leg. Subsequently subjects were randomly divided into a treatment and a sham treatment control group. Repeated fMRI examinations were performed following the administration of the REAC pulse or sham treatment. The Treated group showed cerebellar and ponto-mesencephalic activation components that disappeared in the second scan, while these activation components persisted in the Sham group. This study shows that a very weak signal, such as 250 milliseconds Wi-Fi pulse, administered with REAC technology, could lead to lasting effects on brain activity modification.

    The aim of this single-blind placebo-controlled study was to examine the analgesic effects of interferential currents (IFC) on experimentally induced ischaemic pain. Ischaemic pain was induced using the submaximal effort tourniquet technique (SETT) and pain intensity was recorded using a visual analogue scale at 1-min intervals was used as the primary outcome measure. Following baseline recordings 30 healthy volunteers received either active IFC, sham IFC, or no treatment (10 subjects per group). Data were analysed by calculating the mean change in pain intensity at each 1-min interval by subtracting data during treatment from the baseline data. IFC was administered throughout the duration of the ischaemic pain test via four electrodes (quadripolar application) on the forearm. Active IFC delivered electrical currents at a 'strong but comfortable' intensity. A 'dummy' stimulator that delivered no current was used as sham IFC. Subjects in the no treatment control group were informed that the IFC device was not switched on. There were significant effects for Groups (P=0.04) which were attributed to a significant reduction in pain intensity for the IFC group when compared with sham and no-treatment control (P< or =0.05). There were no significant effects for Time (P=0.69) or Group-Time interaction (P=0.45). In conclusion, IFC produced significantly greater analgesia than sham and no-treatment control groups under the present experimental conditions.

    To compare the analgesic effects of differing swing patterns of interferential current (IFC) on cold-induced pain. Single-blind intervention study in which subjects completed 6 cycles of the cold-induced pain test-2 pretreatment, 2 during treatment, and 2 posttreatment. Laboratory. Forty healthy volunteers. Subjects were randomly allocated to receive 1 of 4 IFC treatment interventions: 1 integral 1, 6 integral 6, 6 wedge 6, or burst. IFC was administered for 20 minutes via 4 electrodes attached to the forearm (quadripolar application) at a strong but comfortable intensity using amplitude-modulated frequencies of 1 to 100 Hz. Change in pain threshold and self-report of pain intensity and unpleasantness from pretreatment baseline. Two-way repeated-measure analysis of variance found significant effects for time and group by time interaction (P<.01), but effects for groups failed to reach statistical significance (P=0.1). This suggests that when all groups are considered together, subjects experience a rise in pain threshold when IFC devices are switched on but not when they are switched off. However, the rise in pain threshold was not dependent on the swing pattern employed. Analysis of pain intensity and unpleasantness ratings found no effects for group or group by time interaction. There were no differences in the hypoalgesic effects of different swing patterns.

    Laparoscopic cholecystectomy (LC) can be technically challenging in the obese. The primary aim of the trial was to establish whether following a Very Low Calorie Diet (VLCD) for two weeks pre-operatively reduces operation time. Secondary outcomes included perceived operative difficulty and length of hospital stay. A single-blinded, randomized controlled trial of consecutive patients with symptomatic gallstones and BMI >30 kg/m(2) 46 patients were randomized to a VLCD or normal diet for two weeks prior to LC. Food diaries were used to document dietary intake. The primary outcome measure was operation time. Secondary outcomes were length of stay, weight change operative complications, day case rates and perceived difficulty of operation. The VLCD was well tolerated and had significantly greater preoperative weight loss (3.48 kg vs. 0.98 kg; p post-operative complications, length of stay, or day case rates between the groups. Dissection of Calot's triangle was deemed significantly easier in the VLCD group. A two week VLCD prior to elective laparoscopic cholecystectomy in obese patients is safe, well tolerated and was shown to significantly reduce pre-operative weight and operative time. 61630192. http://www.isrctn.com/ISRCTN61630192 Trial registration.

    To evaluate the clinical efficacy and safety of Tinospora cordifolia lotion including its cure rate and clearance time compared with permethrin lotion. A single blind, randomized, controlled, pilot clinical study was performed in three government institutions to investigate clinical efficacy of T. cordifolia lotion in sixty-six clinically-diagnosed scabies-infected patients. The patients were treated with T. cordifolia or permethrin lotions for three consecutive days for two weeks and clinical assessment of each patient was performed for five weeks. T. cordifolia lotion and permethrin significantly reduced the mean global evaluation score after four weeks of treatment. The two lotions showed comparable effects as anti-scabies agent. Moreover, the clearance time (days) and cure rate using the two lotions did not differ. Clinical improvement, mean clearance time and cure rate of T. cordifolia lotion are comparable with permethrin. Tinospora cordifolia lotion exhibits anti-scabies activity comparable with permethrin. Its incorporation as therapeutic reagent in Sarcoptes scabiei infections is highly recommended.

    The surgical removal of impacted third molars is one of the most common procedures performed by oral and maxillofacial surgeons. The purpose of this study is to determine whether either transcutaneous or intraoral low-level laser therapy (LLLT) reduces postoperative pain and assists in the healing of mandibular third molar extraction. This randomized, placebo controlled, single-blind, split-mouth design study was conducted on 60 patients with full bony impacted similar position mandibular third molars bilaterally. The patients were divided into two groups of 30 each: transcutaneous LLLT and intraoral LLLT and the other side of each group treated with nonactive laser (60 teeth). The laser treatment consisted of administering laser energy immediately before and after the extraction procedure with gallium aluminum arsenide (GaAlAs) 830 nm diode lasers. Postoperative pain and healing of the sockets were compared in transcutaneous and intraoral group with placebo for 1 week following the extraction. Descriptive and bivariate statistics was computed, and the p-value was set at 0.05. Intraoral LLLT application resulted in a statistically significant reduction of postoperative pain in comparison with transcutaneous laser group and placebo. The unhealed socket numbers were compared in two groups at seventh day and no differences were observed. The results of this study suggest that single-session intraoral LLLT is more effective than extraoral application for reducing postoperative pain. It was postulated that the differences between skin and mucosa could have effect on the results. Although intraoral use would allow closer application to the surgical site, the size of some laser devices precludes their use intraorally.

    To (1) investigate the immediate effects of myofascial induction (MI), with placebo electrotherapy as a control, on perceived pain, cervical/shoulder range of motion (ROM), and mood state in breast cancer survivors (BCSs) with shoulder/arm morbidity; and (2) examine the relationships between pain modifications and cervical/shoulder ROM on the side affected by breast cancer. Randomized, single-blind, placebo-controlled crossover study. Physical therapy laboratory. BCSs (N=21) who had a diagnosis of stage I-IIIA breast cancer and had completed adjuvant therapy (except hormonal treatment). During each session, the BCSs received either an MI (fascial unwinding) intervention focused on the upper limb area following the Pilat approach or placebo pulsed shortwave therapy (control group). Each session lasted 30 minutes, and an adequate washout period of 4 weeks between sessions was established. The visual analog scale (VAS) for pain and anxiety, shoulder-cervical goniometry for ROM, the Profile of Mood States for psychological distress, and the Attitudes Towards Massage Scale were used. An analysis of covariance (ANCOVA) revealed significant time × group interactions for VAS affected arm (P=.031) but not for VAS cervical (P=.332), VAS nonaffected arm (P=.698), or VAS anxiety (P=.266). The ANCOVA also revealed significant interactions for affected shoulder flexion (P<.001), abduction (P<.001), external rotation (P=.004), and internal rotation (P=.001). Significant interactions for affected cervical rotation (P=.022) and affected cervical lateral flexion (P=.038) were also found. A significant negative correlation was found between changes in VAS affected arm and shoulder/arm internal rotation ROM (r=-.46; P=.03). A single MI session decreases pain intensity and improves neck-shoulder ROM to a greater degree than placebo electrotherapy for BCSs experiencing pain.

    Unlike passive sensitivity of implants/teeth that is assessed more, only three controversial studies have compared active tactile sensibility (ATS) of implants and teeth. We aimed to explore the difference between the ATS of teeth and single-tooth implants. The ATS of single-tooth implants and contralateral teeth was measured in 25 patients after they bit on gold and placebo foils 0- to 70-μm thick, each for five times, in a random order blinded to patients and assessor, carried out at two sessions. Based on the experimental range of 0 μm (mock trials) to 70 μm, the sigmoid shape of psychometric curve was estimated to locate the 50% values as the ATS thresholds for each tooth or implant. ATS Data were analyzed using paired and unpaired t-tests and multiple linear regression (α = 0.05, β ≤ 0.1). Also, equivalence testing approach was used to assess semi-objectively the clinical significance. Average ATS values for teeth and implants were 21.4 ± 6.55 μm and 30.0 ± 7.55 μm, respectively (p = .0001 [paired t-test]). None of the geometric characteristics of implants nor duration of implant in function were correlated with the ATS (p > .4 [regression]). Age was positively associated with the ATS of both implants and teeth (p ≤ .019 [regression]). Tooth ATS (but not implant ATS) was significantly higher in males compared with females (p = .050 [unpaired t-test]), which contributed to a generalizable tooth-implant difference higher than 8-μm clinical equivalence margin in females. The ATS was not significantly different between arches or between anterior/posterior regions (p > .6). There was a slight but statistically significant difference between implant and tooth tactile sensitivities. © 2013 Wiley Periodicals, Inc.

    Full Text Available Aims: Serrated polyposis syndrome is a disease that is often missed in the clinical setting and is associated with colorectal cancer. We investigated the prevalence of SPS and the association between colorectal or other cancers in a 10-year, retrospective data analysis. Methods: We reviewed complete colonoscopy data obtained from January 2005 through January 2015 at a health-screening centre. Serrated polyposis syndrome was defined on the basis of the criteria established by the 2010 World Health Organization. Results: Of a total of 53.842 consecutive subjects who underwent complete colonoscopy, 12 (0.022% patients had serrated polyposis syndrome. All of these cases were under-recognized by the endoscopist or referring physician. The mean patient age was 58.6 years; 67% of the patients were men and 33% were women. No serrated polyposis syndrome patients had a first-degree relative with serrated polyposis syndrome, and no serrated polyposis syndrome patients had colorectal cancer. Two cases (17% had extra-colonic cancers (prostate cancer and thyroid cancer. Eight cases (67% had a family history of cancer (stomach, breast, lung, pancreas, prostate and colorectal cancer. Conclusion: Serrated polyposis syndrome was a rare condition in a 10-year database, and it was diagnosed late in all cases. Serrated polyposis syndrome may be associated with an increased risk of extra-colonic cancer

    Full Text Available Abstract Background Advanced resuscitation skills training is an important and enjoyable part of medical training, but requires small group instruction to ensure active participation of all students. Increases in student numbers have made this increasingly difficult to achieve. Methods A single-blind randomised controlled trial of peer-led vs. expert-led resuscitation training was performed using a group of sixth-year medical students as peer instructors. The expert instructors were a senior and a middle grade doctor, and a nurse who is an Advanced Life Support (ALS Instructor. A power calculation showed that the trial would have a greater than 90% chance of rejecting the null hypothesis (that expert-led groups performed 20% better than peer-led groups if that were the true situation. Secondary outcome measures were the proportion of High Pass grades in each groups and safety incidents. The peer instructors designed and delivered their own course material. To ensure safety, the peer-led groups used modified defibrillators that could deliver only low-energy shocks. Blinded assessment was conducted using an Objective Structured Clinical Examination (OSCE. The checklist items were based on International Liaison Committee on Resuscitation (ILCOR guidelines using Ebel standard-setting methods that emphasised patient and staff safety and clinical effectiveness. The results were analysed using Exact methods, chi-squared and t-test. Results A total of 132 students were randomised: 58 into the expert-led group, 74 into the peer-led group. 57/58 (98% of students from the expert-led group achieved a Pass compared to 72/74 (97% from the peer-led group: Exact statistics confirmed that it was very unlikely (p = 0.0001 that the expert-led group was 20% better than the peer-led group. There were no safety incidents, and High Pass grades were achieved by 64 (49% of students: 33/58 (57% from the expert-led group, 31/74 (42% from the peer-led group. Exact

    Local forearm warming before tourniquet application is often used to promote venodilation for peripheral intravenous cannulation; however, few studies have compared the effect of tourniquet application with and without local warming on vein size. To evaluate the effectiveness of tourniquet application after local forearm warming with that of tourniquet application alone in young and middle-aged adults. A single-blind, prospective, parallel group, randomized controlled trial. A national university in Japan. Seventy-two volunteers aged 20-64 years. Participants were randomly allocated to one of two groups: tourniquet application for 30s after forearm application of a heat pack warmed to 40°C±2°C for 15min (active warming group; n=36) or tourniquet application for 30s after applying a non-warmed heat pack for 15min (passive warming group; n=36). The primary outcomes were vein cross-sectional area on the forearm, measured after the intervention by blinded research assistants using ultrasound. Secondary outcomes were shortest diameter, and longest diameter of vein on the forearm, forearm skin temperature, body temperature, pulse, systolic blood pressure, and diastolic blood pressure. All outcomes were assessed at the same site before and immediately after the intervention, once per participant. Vein cross-sectional area, shortest vein diameter, and longest vein diameter were significantly increased in the active warming group compared with the passive warming group (p application after local warming was superior to tourniquet application alone in increasing vein cross-sectional, shortest diameter, and longest diameter (between-group differences of 2.2mm 2 , 0.5mm, and 0.5mm, respectively), and in raising skin temperature (between-group difference: 5.2°C). However, there were no significant differences in body temperature, pulse, or systolic or diastolic blood pressure between the groups. There were no adverse events associated with either intervention. Tourniquet

    Botulinum toxin injection has been applied for pain relief in various chronic pain syndromes. Recently, systematic review studies reported inconclusive effects of Botulinum toxin in myofascial pain management. The present study aimed to demonstrate the efficacy and safety of Botulinum toxin type A (BTxA) (Botox®) injection for pain reduction in myofascial trigger point (MTrP) of the upper trapezius muscle. Thirty-three patients with 48 MTrP on the upper trapezius muscles over three months with moderate to severe pain intensity diagnosed at physical medicine and rehabilitation outpatient department were recruited between December 2011 and March 2012. Eligible patients were blinded and randomly injected with single 0.2 ml (20 IU) of BTxA for 24 MTrP and 0.2 ml of 0.9% NaCl solution for 24 MTrP at the most tender trigger point on the upper trapezius muscle. All patients were advised for stretching exercise and ergonomic adaptation throughout the study. At 3- and 6-week after injections, visual analogue scale (VAS), the pressure pain threshold (PPT), and reported adverse effects were measured. Both BTxA and control groups demonstrated statistically significant differences in VAS reduction and increased PPT after 3 weeks and 6 weeks compared with before treatment. There were no statistically significant differences in VAS reduction from baseline between the two groups at 3- and 6-week after treatment. A statistically significant difference in improvement of PPT from baseline and 6-week after BTxA injection compared with 0.9% NaCl group was shown (1.0 ± 0.9 and 0.5 ± 0.7, p = 0.036). There was mild degree side-effects that spontaneous resolved within one week in both groups without significant difference in percentage. No severe adverse effects were reported during the study. The efficacy in VAS reduction of a single 20 IU of Botulinum toxin type A (Botox®) injection was not different from 0.9% NaCl for myofascial trigger point at the upper trapezius muscle. However

    The objective was to describe the management and risk factors for complications of antiphospholipid syndrome (APS) patients who underwent a surgical procedure in a single center. We reviewed medical records of all patients with primary or secondary APS who underwent an elective surgery during a 6-year period. Demographical data, management of anticoagulation and complications were recorded. We identified 43 patients, mean age 37.9 ± 8.9 years, who underwent a total of 48 elective surgeries. All patients had history of at least one thrombotic event and were under vitamin K antagonists. Before surgery, all patients received bridging therapy with intravenous infusion of heparin or low molecular weight heparin (LMWH). Among the LMWH group, 36 had a full anticoagulation regimen and nine prophylactic doses. In 62% of the surgeries, we identified an optimal management of periprocedural anticoagulation according to guidelines. Overall six patients had severe bleeding and three thrombotic complications (full anticoagulation regimen n = 2 and prophylactic dose group n = 1). Patients with optimal management of anticoagulation experienced less thrombotic and hemorrhagic complications (7 vs. 33%; OR 0.14, 95% CI 0.02-0.81; p = 0.040) and patients with INR ≤1.5 at surgery had fewer episodes of major bleeding (6 vs. 29%; OR 0.19, 95% CI 0.02-0.98; p = 0.050). All three thrombotic events occurred in patients with INR ≤1.5. Proper management of anticoagulation based on guidelines is associated with less complications in patients with APS. Notwithstanding the proper use of bridging therapy, some patients may develop thrombotic complications.

    Unilateral sensorineural hearing loss (USNHL)/single-side deafness (SSD) is a frequently encountered disability in children. The etiology of a substantial portion of USNHL/SSD still remains unknown, and genetic causes have not been clearly elucidated. In this study, the authors evaluated the heritability of USNHL/SSD.The authors sequentially recruited 50 unrelated children with SSD. For an etiologic diagnosis, we performed a rigorous review on the phenotypes of family members of all children and conducted, if necessary, molecular genetic tests including targeted exome sequencing of 129 deafness genes.Among the 50 SSD children cohort, the authors identify 4 (8%) unrelated SSD probands from 4 families (SH136, SB173, SB177, and SB199) with another hearing impaired family members. Notably, all 4 probands in our cohort with a familial history of SSD also have pigmentary abnormalities such as brown freckles or premature gray hair within first degree relatives, which may indicate that genes whose products are involved with pigmentary disorder could be candidates for heritable SSD. Indeed, SH136 and SB199 turned out to segregate a mutation in MITF and PAX3, respectively, leading to a molecular diagnosis of Waardenburg syndrome (WS).We report, for the first time in the literature, a significant heritability of pediatric SSD. There is a strong association between the heritability of USNHL/SSD and the pigmentary abnormality, shedding a new light on the understanding of the molecular basis of heritable USNHL/SSD. In case of children with congenital SSD, it would be mandatory to rigorously screen pigmentary abnormalities. WS should also be included in the differential diagnosis of children with USNHL/SSD, especially in a familial form.

    Physical and occupational therapists have started to use the Nintendo Wii™ gaming system with adults and children as part of their regular treatment. Despite the growing use of the Wii and trend towards evidence-based practice, limited evidence is available on the effectiveness of virtual reality using the Wii for children with developmental delay. The purpose of this study was to determine the feasibility and preliminary effectiveness of a low-cost gaming system for young children with developmental delay. Single-blind, randomised controlled trial. Forty children with developmental delay (age 39 to 58 months) who attended a segregated or integrated preschool participated in this study. All children's parents read and signed an informed consent form approved by the institutional review board. Children were assigned at random to an experimental (Wii) group (n=20) or a control group (n=20). Two weekly sessions for 10 weeks using Nintendo Wii Sports™ and Nintendo Wii Fit™, including balance, strength training and aerobics games. Participants were evaluated 1 week before and 1 week after the programme by a blinded investigator. Primary outcomes were gait speed, timed up and go test, single leg stance test, five-times-sit-to-stand test, timed up and down stairs test, 2-minute walk test and grip strength. The Gross Motor Function Measure (GMFM) was used to assess gross motor skills. The two groups were homogenous regarding all parameters at baseline. The Wii training was feasible and enjoyable for those in the experimental group. There were no adverse effects or injuries reported over 267 training sessions. Comparison of groups following the intervention indicated that the experimental group showed significant improvements compared with the control group in single leg stance test {mean difference 1.03 [standard deviation (SD) 1.7], 95% confidence interval (CI) 0.2 to 1.9; P=0.017}, right grip strength [mean difference 1.11 (SD 1.84), 95% CI 0.15 to 2.06; P=0

    To present data of standardized ambulatory urodynamic monitoring (AUM) performed in women with overactive bladder syndrome (OAB) and to evaluate the relevance of AUM data with clinical findings of the patients. Records of women with symptoms of OAB were retrospectively reviewed (n=249). Of women fulfilling the Overactive Bladder Awareness Tool (OAB-V8) with a score ≥8 and the 3-day voiding diary (VD) with a frequency >7/day (n=167), those who underwent urodynamic investigation were selected (n=76). The data of this study were retrieved from the records of Ankara University Cebeci Hospital and based on the AUM findings of single voiding cycle of women with OAB. AUM, which is among the institutionally approved primary urodynamic investigation methods, is performed with LUNA ambulatory monitoring recorder (MMS™) in the clinical setting with a standardized technique, in reproducing lower urinary tract symptoms of women since 2011. The relationship of the urodynamic data with the clinical findings were evaluated. AUM traces of women (n=76) with OAB revealed 63.1% DO, 64.4% urgency and 77.7% urinary incontinence of which were 14.4% urgency urinary incontinence (UUI), 25% stress urinary incontinence (SUI) and 38.1% mixed urinary incontinence (MUI). OAB patients with DO reported more urinary incontinence episodes/day, nocturia and mixed urinary incontinence in the voiding diary (p<0.04) and had significantly higher irritative symptom bother reflected by the questionnaires (p<0.04). Women with DO were more likely to be postmenopausal (p=0.02) and were found to have more urgency (p<0.001), urgency episodes (p=0.05) and incontinence (urge and mixed) (p<0.001). However, no association was found between the extent of pelvic organ prolapse and the presence of DO. AUM performed with a standardized technique during single voiding cycle seems to be a reliable method in reproducing symptoms of women with OAB. It provides both clinically relevant findings and objective

    The treatment of knee osteoarthritis with hyaluronic acid or corticosteroid injection has been widely used. The purpose of this study was to compare the efficacy of hyaluronic acid (hylan G-F 20) with triamcinolone acetonide as a single intra-articular injection for knee osteoarthritis. This study was a prospective, randomized, double-blind clinical trial. Participants with symptomatic knee osteoarthritis were recruited. They were randomized to receive a single-shot, intra-articular injection of either 6 mL of hylan G-F 20 or 6 mL of a solution comprising 1 mL of 40-mg triamcinolone acetonide and 5 mL of 1% lidocaine with epinephrine. The primary outcomes were knee pain severity, knee function, and range of motion at 6 months. Ninety-nine patients were assessed before injection and underwent a 6-month follow-up. Patients and evaluators were blinded. Multilevel regression models were used to estimate differences between the groups. At the 6-month follow-up, compared with patients who took hylan G-F 20, patients who took triamcinolone acetonide had similar improvement in knee pain, knee function, and range of motion. The difference in mean outcome scores between groups was, with regard to knee pain, a visual analog scale (VAS) score of 3 points (95% confidence interval [95% CI], -6 to 11 points); with regard to knee function, a modified Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score of 0 points (95% CI, -8 to 6 points); and, with regard to range of motion, flexion of -1° (95% CI, -5° to 2°) and extension of 0° (95% CI, -0.5° to 0.5°). However, patients who took triamcinolone acetonide had better pain improvement from 24 hours until 1 week after injection; the mean difference between groups with regard to the VAS score was 12 points (95% CI, 5 to 20 points; p = 0.002) at 24 hours and 9 points (95% CI, 1 to 15 points; p = 0.018) at 1 week. At 2 weeks after injection, patients who took triamcinolone acetonide also had better knee

    Alcohol Use Disorder is a highly prevalent mental disorder which puts a severe burden on individuals, families, and society. The treatment of Alcohol Use Disorder is challenging and novel and innovative treatment approaches are needed to expand treatment options. A promising neuroscience-based intervention method that allows targeting cortical as well as subcortical brain processes is real-time functional magnetic resonance imaging neurofeedback. However, the efficacy of this technique as an add-on treatment of Alcohol Use Disorder in a clinical setting is hitherto unclear and will be assessed in the Systems Biology of Alcohol Addiction (SyBil-AA) neurofeedback study. N = 100 patients with Alcohol Use Disorder will be randomized to 5 parallel groups in a single-blind fashion and receive real-time functional magnetic resonance imaging neurofeedback while they are presented pictures of alcoholic beverages. The groups will either downregulate the ventral striatum, upregulate the right inferior frontal gyrus, negatively modulate the connectivity between these regions, upregulate, or downregulate the auditory cortex as a control region. After receiving 3 sessions of neurofeedback training within a maximum of 2 weeks, participants will be followed up monthly for a period of 3 months and relapse rates will be assessed as the primary outcome measure. The results of this study will provide insights into the efficacy of real-time functional magnetic resonance imaging neurofeedback training in the treatment of Alcohol Use Disorder as well as in the involved brain systems. This might help to identify predictors of successful neurofeedback treatment which could potentially be useful in developing personalized treatment approaches. The study was retrospectively registered in the German Clinical Trials Register (trial identifier: DRKS00010253 ; WHO Universal Trial Number (UTN): U1111-1181-4218) on May 10th, 2016.

    Full Text Available Background: Subjects with knee osteoarthritis typically have higher knee adduction moment. Current research efforts are mainly focused on therapeutic procedures that potentially may modify disease progression. This preliminary study was designed as a single blind (examiner randomized control trial to investigate the impact of conventional physical therapy on pain, and knee joint load in subjects with moderate knee osteoarthritis. Methods: Twelve participants diagnosed with moderate knee OA were randomly assigned into control and intervention groups. Three-dimensional knee kinematic and kinetic data were recorded during the gait before and after 10 sessions of conventional physical therapy. In addition, pain intensity was evaluated by visual analog scale and pain subscale of KOOS questionnaire. The control group did not receive any intervention during the same period. Gait parameters were analyzed within and between groups using nonparametric tests. Results: There was a significant difference between groups in baseline KOOS-pain Score and ML knee force (P=0.048 and P=0.01. Immediately after ten sessions of physical therapy the initial (first peak of knee adduction moment was significantly (P=0.03 lower than that of the control group while the first and second peak of knee AP velocity were significantly (P=0.02, P=0.01 respectively higher. In the intervention group, the second peaks of vertical and anteroposterior (AP knee forces were strongly correlated with the pretest KOOS-pain Score (r=0.99 and r=0.98, P<0.001. Therefore a multivariate general linear model was adopted with adjustment to baseline KOOS-pain. By this adjustment, 51% alleviation of VAS pain score and 81% decrement of first peak of knee adduction moment in comparison to control group was statistically significant (P=0.02, P=0.03 respectively. Conclusion: It seems that ten sessions of conventional physical therapy may modify knee joint load in subjects with moderate knee

Aims and Objectives: This study aims to compare the treatment with monoherbal formulation of Holarrhena antidysenterica with Mesalamine in chronic ulcerative colitis patients with special emphasis to side effects and relapse. Settings and Design: Patients were enrolled from an Ayurveda Hospital and a private Hospital, Gujarat. The study was randomized, parallel group and single blind design. Materials and Methods: The protocol was approved by Institutional Human Research Ethics Committee of Anand Pharmacy College on 23rd Jan 2013. Three groups (n = 10 were treated with drug Mesalamine (Group I, monoherbal tablet (Group II and combination of both (Group III respectively. Baseline characteristics, factors affecting quality of life, chronicity of disease, signs and symptoms, body weight and laboratory investigations were recorded. Side effects and complications developed, if any were recorded during and after the study. Statistical Analysis Used: Results were expressed as mean ± SEM. Data was statistically evaluated using t-test, Wilcoxon test, Mann Whitney U test, Kruskal Wallis test and ANOVA, wherever applicable, using GraphPad Prism 6. Results: All the groups responded positively to the treatments. All the patients were positive for occult blood in stool which reversed significantly after treatment along with rise in hemoglobin. Patients treated with herbal tablets alone showed maximal reduction in abdominal pain, diarrhea, and bowel frequency and stool consistency scores than Mesalamine treated patients. Treatment with herbal tablet alone and in combination with Mesalamine significantly reduced the stool infection. Patients treated with herbal drug alone and in combination did not report any side effects, relapse or complications while 50% patients treated with Mesalamine exhibited the relapse with

    Palmar hyperhidrosis is a common disorder of excessive sweating. A number of studies have demonstrated the effectiveness of iontophoresis in the treatment of palmar hyperhidrosis. However, controlled clinical studies on iontophoresis for palmar hyperhidrosis have been limited. To determine the efficacy and safety of iontophoresis in the treatment of palmar hyperhidrosis with a randomized, sham-controlled, single-blind, and parallel-designed study. Twenty nine patients with significant palmar hyperhidrosis were enrolled in this study. They received active iontophoresis treatment (group A) or sham treatment (group B). Iontophoresis was performed 20 minutes each time, five times per week, for 2 weeks. Its efficacy was assessed with starch-iodine test, mean sweat secretion rate, and hyperhidrosis disease severity scale. Twenty-seven of the 29 patients completed the 2-week treatment. After completion of 10 times of treatment, results of the starch-iodine test showed clinical improvement in 92.9% of patients in group A and 38.5% of patients in group B ( p =0.001). The mean sweat secretion rate was reduced by 91.8% of patients in group A and by 39.1% of patients in group B ( p <0.001). Improvement in quality of life was reported by 78.6% of patients in group A and by 30.8% of patients in group B ( p =0.028). In group A, one case of localized adverse event was noted, although no adverse event was encountered in group B. Tap water iontophoresis could be used as an effective and safe treatment modality for palmar hyperhidrosis.

    2012-01-01

    Background Non-specific chronic low back pain (NSCLBP) is one of the most common musculoskeletal disorders around the world including Iran. One of the most widely used modalities in the field of physiotherapy is therapeutic ultrasound (US). Despite its common use, there is still inconclusive evidence to support its effectiveness in patients with NSCLBP. The objective of this study was to evaluate the effect of continuous US compared with placebo US additional to exercise therapy for patients with NSCLBP. Methods In this single blind placebo controlled study, 50 patients with NSCLBP were randomized into two treatment groups: 1) continuous US (1 MHz &1.5 W/cm2) plus exercise 2) placebo US plus exercise. Patients received treatments for 4 weeks, 10 treatment sessions, 3 times per week, every other day. Treatment effects were assessed in terms of primary outcome measures: 1) functional disability, measured by Functional Rating Index, and 2) global pain, measured by a visual analog scale. Secondary outcome measures were lumbar flexion and extension range of motion (ROM), endurance time and rate of decline in median frequency of electromyography spectrum during a Biering Sorensen test. All outcome variables were measured before, after treatment, and after one-month follow-up. An intention to treat analysis was performed. Main effects of Time and Group as well as their interaction effect on outcome measures were investigated using repeated measure ANOVA. Results Analysis showed that both groups had improved regarding function (FRI) and global pain (VAS) (P .05). Improvement in function and lumbar ROM as well as endurance time were significantly greater in the group receiving continuous US (P exercise program significantly improved function, lumbar ROM and endurance time. Further studies including a third group of only exercise and no US can establish the possible effects of placebo US. Trial registration NTR2251 PMID:23031570

    ABSTRACT This phase IV, single blind study assessed the immunogenicity and safety of India-manufactured purified chick embryo cell rabies vaccine (PCECV), compared with a German-manufactured batch obtained by the same production process. A total of 340 participants enrolled at 2 study sites in India were randomized (1:1:1:1) in 4 groups to receive a 5-dose Essen regimen with either 1 of the 3 Indian batches (PCECV-I) or the German batch (PCECV-G), administered on Days (D) 0, 3, 7, 14 and 30. The lot-to-lot consistency of PCECV-I batches in terms of induced immune response at D14 was demonstrated. The immune response elicited by PCECV-I was shown to be non-inferior to that induced by PCECV-G, as the lower limit of the 95% confidence interval for the ratio (PCECV-I/PCECV-G) of rabies virus neutralising antibody (RVNA) geometric mean concentrations was higher than 0.5 at D14. At least 96% of participants developed adequate RVNA concentrations (≥ 0.5 IU/mL) by D14 and all achieved RVNA concentrations ≥ 0.5 IU/mL by D90. RVNA levels were comparable across all groups throughout the entire study. Solicited local and general symptoms had a similar incidence in all groups. Unsolicited adverse events (AEs) were reported by 11% of participants. Only 1 serious AE (leg fracture) was reported and was not related to vaccination. No deaths and no rabies cases were recorded during the 90 days of observation. The study showed that the 3 PCECV-I and the PCECV-G batches induced a similar immune response and had a comparable safety profile when administered according to a 5-dose schedule. PMID:28406752

    Full Text Available Standard treatment of cutaneous leishmaniasis (CL in Suriname entails three injections of pentamidine isethionate (PI 4 mg/kg per injection in 7 days (7 day regimen. Compliance to treatment is low and may contribute to increasing therapy failure. A 3 day regimen, including 2 injections of 7 mg/kg in 3 days may increase compliance.In a randomized, single-blinded non-inferiority trial conducted in Suriname, 84 CL patients received the 7 day regimen and 79 CL patients received the 3 day regimen. Primary objective was the proportion of patients clinically cured at 6 weeks follow-up. Secondary objectives were clinical cure at 12 weeks follow-up; parasitological cure at 6 and 12 weeks; adverse and drug related toxicity events recorded one week after the end of treatment and health related quality of life. The non-inferiority margin was set at 15%, 1 sided test, α = 0.1.At 6 weeks follow-up 31 (39% patients in the 3 day regimen and 41 (49% patients in the 7 day regimen were clinically cured. Intention to treat (ITT analyses showed that the difference in proportion clinically cured was -9.6% (90% Confidence Interval (CI: -22.3% to 3.2%. Per protocol (PP analysis showed that the difference in proportion clinically cured was 0.2% (90% CI: -14.6% to 15.2%. ITT analysis showed that the difference in proportion parasitological cured at 6 weeks was -15.2% (90% CI:-28.0% to -2.5%. PP analyses showed similar results. Non-inferiority could not be concluded for all adverse and toxicological events.We cannot conclude that the 3 day regimen is non-inferior to the 7 day regimen regarding proportion clinically and parasitological cured. Therefore there is no evidence to change the current standard practice of the 7 day regimen for the treatment of CL in Suriname.

    Full Text Available Abstract Background Self-tests, tests on body materials to detect medical conditions, are widely available to the general public. Self-testing does have advantages as well as disadvantages, and the debate on whether self-testing should be encouraged or rather discouraged is still ongoing. One of the concerns is whether consumers have sufficient knowledge to perform the test and interpret the results. An online decision aid (DA with information on self-testing in general, and test specific information on cholesterol and diabetes self-testing was developed. The DA aims to provide objective information on these self-tests as well as a decision support tool to weigh the pros and cons of self-testing. The aim of this study is to evaluate the effect of the online decision aid on knowledge on self-testing, informed choice, ambivalence and psychosocial determinants. Methods/Design A single blind randomised controlled trial in which the online decision aid 'zelftestwijzer' is compared to short, non-interactive information on self-testing in general. The entire trial will be conducted online. Participants will be selected from an existing Internet panel. Consumers who are considering doing a cholesterol or diabetes self-test in the future will be included. Outcome measures will be assessed directly after participants have viewed either the DA or the control condition. Weblog files will be used to record participants' use of the decision aid. Discussion Self-testing does have important pros and cons, and it is important that consumers base their decision whether they want to do a self-test or not on knowledge and personal values.

    Self-tests, tests on body materials to detect medical conditions, are widely available to the general public. Self-testing does have advantages as well as disadvantages, and the debate on whether self-testing should be encouraged or rather discouraged is still ongoing. One of the concerns is whether consumers have sufficient knowledge to perform the test and interpret the results. An online decision aid (DA) with information on self-testing in general, and test specific information on cholesterol and diabetes self-testing was developed. The DA aims to provide objective information on these self-tests as well as a decision support tool to weigh the pros and cons of self-testing. The aim of this study is to evaluate the effect of the online decision aid on knowledge on self-testing, informed choice, ambivalence and psychosocial determinants. A single blind randomised controlled trial in which the online decision aid 'zelftestwijzer' is compared to short, non-interactive information on self-testing in general. The entire trial will be conducted online. Participants will be selected from an existing Internet panel. Consumers who are considering doing a cholesterol or diabetes self-test in the future will be included. Outcome measures will be assessed directly after participants have viewed either the DA or the control condition. Weblog files will be used to record participants' use of the decision aid. Self-testing does have important pros and cons, and it is important that consumers base their decision whether they want to do a self-test or not on knowledge and personal values. This study is the first to evaluate the effect of an online decision aid for self-testing. Dutch Trial Register: NTR3149.

    Anxiety and pain are recognized as major problems of burn patients; because pharmaceutical treatments for controlling anxiety and pain symptoms lead to complications and an increase in health costs, nonpharmacological nursing interventions were considered for this group of patients. This led to the present study aimed at comparing the effect of aromatherapy massage with inhalation aromatherapy for anxiety and pain in burn patients. This single-blind clinical trial was carried out on 90 patients with burns aromatherapy massage, inhalation aromatherapy, and control group. The patients assigned to the aromatherapy massage group received a massage for half an hour using a blend of lavender and almond oils, while a blend of rose and lavender aroma was used for the inhalation aromatherapy group. Spielberger State Anxiety Inventory was used for measuring anxiety and the visual analog scale (VAS) scale was used for measuring pain. The results showed that three groups were equal in terms of demographics, disease characteristics, and scores of anxiety and pain at the baseline. The mean decreases of anxiety scores were -0.04±5.08, 6.33±12.55, and 6.43±10.60 in the control group, aromatherapy massage group, and inhalation group, respectively (p=0.007). The mean decrease of pain scores were -0.10±0.96, 1.70±1.84, and 0.97±1.56 in the control group, aromatherapy massage group, and inhalation group, respectively (paromatherapy massage and inhalation aromatherapy compared with the control group in reducing both anxiety and pain of burn patients. Therefore, both interventions, which are inexpensive, and noninvasive nursing tasks can be proposed for alleviating anxiety and pain of burn patients. Copyright © 2016 Elsevier Ltd and ISBI.

    Full Text Available The probiotic strain Lactobacillus plantarum 299v has earlier been shown to increase iron absorption when added to foods. However, it is not known if the same probiotic strain in a freeze-dried format included in a capsule increases the iron absorption.The aim of this study was to test the hypotheses that non-heme iron absorption from a light meal is promoted by a simultaneous intake of freeze-dried Lactobacillus plantarum 299v (Lp299v, DSM 9843.With a single blinded placebo controlled sequential design, iron absorption from a light breakfast meal administered with or without capsules containing 1010 cfu freeze-dried Lp299v was studied in healthy female volunteers of fertile age. The methodology used was a double isotope technique (59Fe and 55Fe. Two studies were performed using the same protocol.In study 1, the absorption of iron from a meal without Lp299v was found to be 17.4 ± 13.4%, and from an identical meal with Lp299v was found to be 22.4 ± 17.3% (mean ± SD. This difference was statistically significant (p = 0.040, n = 14. In study 2, the absorption of iron from a meal without Lp299v was found to be 20.9 ± 13.1%, and from an identical meal with Lp299v found to be 24.5 ± 12.0% (mean ± SD, n = 28, which again was statistically significant (p = 0.003.Freeze-dried Lp299v enhances the absorption of iron when administered together with a meal with a high iron bioavailability.ClinicalTrials.gov Identifier: NCT02131870.

    Full Text Available Abstract Background Influenza vaccines are recommended for administration by the intramuscular route. However, many physicians use the subcutaneous route for patients receiving an oral anticoagulant because this route is thought to induce fewer hemorrhagic side effects. Our aim is to assess the safety of intramuscular administration of influenza vaccine in patients on oral anticoagulation therapy. Methods Design: Randomised, controlled, single blinded, multi-centre clinical trial. Setting: 4 primary care practices in Barcelona, Spain. Participants: 229 patients on oral anticoagulation therapy eligible for influenza vaccine during the 2003–2004 season. Interventions: intramuscular administration of influenza vaccine in the experimental group (129 patients compared to subcutaneous administration in the control group (100 patients. Primary outcome: change in the circumference of the arm at the site of injection at 24 hours. Secondary outcomes: appearance of local reactions and pain at 24 hours and at 10 days; change in INR (International Normalized Ratio at 24 hours and at 10 days. Analysis was by intention to treat using the 95% confidence intervals of the proportions or mean differences. Results Baseline variables in the two groups were similar. No major side effects or major haemorrhage during the follow-up period were reported. No significant differences were observed in the primary outcome between the two groups. The appearance of local adverse reactions was more frequent in the subcutaneous administration group (37,4% vs. 17,4%, 95% confidence interval of the difference 8,2% to 31,8%. Conclusion This study shows that the intramuscular administration route of influenza vaccine in patients on anticoagulant therapy does not have more side effects than the subcutaneous administration route.

    Background: Psychological distress, biomedical parameters, and unhealthy lifestyles contribute to a poorer prognosis for cardiac disease. Public health's challenge is to motivate patients to utilize self-care. Objective: This prospective, randomized, single-blind pilot study aimed at testing the incremental efficacy of Brief Strategic Therapy (BST) combined with Motivational Interviewing (MI) in improving selected biomedical and psychological outcomes over and beyond those of the stand-alone BST in a residential Cardiac Rehabilitation (CR) program. Method: Fourty-two inpatients (17 females), enrolled in a 1-month CR program, were randomly allocated into two conditions: (a) Three sessions of BST and (b) Three sessions of BST plus MI. Data were collected at baseline, discharge, and after 3 months through phone interviews. Results: At discharge, no significant between-group difference was found in any outcome variable. Changes from pre- to post-treatment within each condition showed significant improvements only in the BST group, where the level of external regulation diminished, and both the participants' self-regulation (Relative Autonomous Motivation Index, RAI) and willingness to change improved. At the 3-month follow-up, within-group analyses on responders (BST = 9; BST + MI = 11) showed a statistically significant improvement in the level of systolic blood pressure in both groups. Discussion: Findings showed no evidence of the incremental efficacy of combining BST and MI over and beyond BST alone on either selected biomedical or psychological outcomes among CR patients. Conclusions: Ends and limitations from the present pilot study should be considered and addressed in future investigations.

    Purpose: To evaluate and compare peri-implant health, marginal bone loss and success of immediate and delayed implant placement for rehabilitation with full-arch fixed prostheses. Material and Methods: The present study was a prospective, randomized, single-blind, clinical preliminary trial. Patients were randomized into two treatment groups. In Group A implants were placed immediately post-extraction and in Group B six months after extraction. The following control time-points were established: one week, six months and twelve months after loading. Measurements were taken of peri-implant crevicular fluid volume, plaque index, gingival retraction, keratinized mucosa, probing depth, modified gingival index and presence of mucositis. Implant success rates were evaluated for the two groups. The study sample included fifteen patients (nine women and six men) with a mean average age of 63.7 years. One hundred and forty-four implants were placed: 76 placed in healed sites and 68 placed immediately. Results: At the moment of prosthetic loading, keratinized mucosa width and probing depth were higher in immediate implants than delayed implants, with statistically significant differences. However, after six and twelve months, differences between groups had disappeared. Bone loss was 0.54 ± 0.39 mm for immediate implants and 0.66 ± 0.25 mm for delayed implants (p=0.201). No implants failed in either group. Conclusions: The present study with a short follow-up and a small sample yielded no statistically significant differences in implant success and peri-implant marginal bone loss between immediate and delayed implants with fixed full-arch prostheses. Peri-implant health showed no statistically significant differences for any of the studied parameters (crevicular fluid volume, plaque index, gingival retraction, keratinized mucosa, probing depth, modified gingival index and presence of mucositis) at the twelve-month follow-up.

    Isomaltulose, a naturally-occurring isomer of sucrose, is commonly used as an alternative sweetener in foods and beverages. The goal of this study was to determine the effect of isomaltulose together with green tea on postprandial plasma glucose and insulin concentration, as well as antioxidant capacity in healthy subjects. In a randomized, single-blind, crossover study, 15 healthy subjects (eight women and seven men; ages 23.5 ± 0.7 years; with body mass index of 22.6 ± 0.4 kg/m²) consumed five beverages: (1) 50 g sucrose in 400 mL water; (2) 50 g isomaltulose in 400 mL of water; (3) 400 mL of green tea; (4) 50 g sucrose in 400 mL of green tea; and (5) 50 g isomaltulose in 400 mL of green tea. Incremental area under postprandial plasma glucose, insulin, ferric reducing ability of plasma (FRAP) and malondialdehyde (MDA) concentration were determined during 120 min of administration. Following the consumption of isomaltulose, the incremental 2-h area under the curve (AUC 0-2 h ) indicated a higher reduction of postprandial glucose (43.4%) and insulin concentration (42.0%) than the consumption of sucrose. The addition of green tea to isomaltulose produced a greater suppression of postprandial plasma glucose (20.9%) and insulin concentration (37.7%). In accordance with antioxidant capacity, consumption of sucrose (40.0%) and isomaltulose (28.7%) caused the reduction of green tea-induced postprandial increases in FRAP. A reduction in postprandial MDA after drinking green tea was attenuated when consumed with sucrose (34.7%) and isomaltulose (17.2%). In conclusion, green tea could enhance the reduction of postprandial glucose and insulin concentration when consumed with isomaltulose. In comparison with sucrose, isomaltulose demonstrated less alteration of plasma antioxidant capacity after being consumed with green tea.

    Virtual reality (VR)-based rehabilitation has been reported to have beneficial effects on upper extremity function in stroke survivors; however, there is limited information about its effects on distal upper extremity function and health-related quality of life (HRQoL). The purpose of the present study was to examine the effects of VR-based rehabilitation combined with standard occupational therapy on distal upper extremity function and HRQoL, and compare the findings to those of amount-matched conventional rehabilitation in stroke survivors. The present study was a single-blinded, randomized controlled trial. The study included 46 stroke survivors who were randomized to a Smart Glove (SG) group or a conventional intervention (CON) group. In both groups, the interventions were targeted to the distal upper extremity and standard occupational therapy was administered. The primary outcome was the change in the Fugl-Meyer assessment (FM) scores, and the secondary outcomes were the changes in the Jebsen-Taylor hand function test (JTT), Purdue pegboard test, and Stroke Impact Scale (SIS) version 3.0 scores. The outcomes were assessed before the intervention, in the middle of the intervention, immediately after the intervention, and 1 month after the intervention. The improvements in the FM (FM-total, FM-prox, and FM-dist), JTT (JTT-total and JTT-gross), and SIS (composite and overall SIS, SIS-social participation, and SIS-mobility) scores were significantly greater in the SG group than in the CON group. VR-based rehabilitation combined with standard occupational therapy might be more effective than amount-matched conventional rehabilitation for improving distal upper extremity function and HRQoL.

    To evaluate the efficacy, safety, satisfaction, discomfort and patient preference of moxa cones of artemisia vulgaris and charcoal moxa. This comparative study of moxibustion treatment with Artemisia vulgaris and charcoal moxa cone stimulating Zhongwan (CV 12) is a cross-over single-blinded, randomized clinical trial. A total of 40 healthy subjects (24 males and 16 females) participated in this study. Two subjects dropped out of the trial. Thirty-eight subjects were treated with Artemisia vulgaris and charcoal moxa cones for 30 min in a cross-over design. After treatment, the patients underwent a 30 minute waiting period, and then the temperatures at Tanzhong (CV 17), Zhongwan (CV 12) and Guanyuan (CV 4) were measured using digital infrared thermal imaging. After the use of Artemisia vulgaris moxa, the patients' body temperatures were slightly lowered at Tanzhong (CV 17), Zhongwan (CV 12) and Guanyuan (CV 4), but the changes were not statistically significant. After the use of charcoal moxa, the patients' body temperatures were somewhat increased at Zhongwan (CV 12) and Guanyuan (CV 4), but the changes were not statistically significant. After Artemisia vulgaris moxa use, the body temperature difference between Zhongwan (CV 12) and Guanyuan (CV 4) was significantly increased. After charcoal moxa use, the body temperature difference between Tanzhong (CV 17) and Zhongwan (CV 12) was significantly decreased in males and in the whole group. This change was caused by the difference in the moxibustion type and by gender differences. This pilot study found that moxibustion did not raise the body temperature, but temperature differences between acupoints were affected. Further large-scale randomized controlled trials are needed for the effect of moxibustion on body temperature.

Materials and Methods: In a randomized single-blinded clinical trial, 36 patients with knee OA were randomly assigned to two study groups. Both groups received exercise and medical therapy for 6 weeks. In addition, the first group (20 patients received taping in the first 3 weeks. Pain severity (assessed by visual analog scaling, weekly amount of analgesics consumption, timed get up and go test (TUG, and step tests were recorded at baseline, 3 and 6 weeks after the treatment and were further compared between two study groups. Results: There was no significant difference between two groups in pain severity score (P = 0.228, step test score (P = 0.771, TUG test score (P = 0.821 and weekly amount of analgesics consumption (P = 0.873 at baseline. After 3 weeks, weekly amount of analgesics consumption (P = 0.006, pain severity (P < 0.001 was significantly lower in taping group whereas step test score (P = 0.006 was significantly higher in the taping group. After 6 weeks, patients in taping group had significantly lower pain severity (P = 0.011 and higher step test score (P = 0.042. However, there was no significant difference in TUG test score (P = 0.443 and weekly amount of analgesics consumption (P = 0.270 between two groups. Conclusion: Therapeutic knee taping may be an effective method for short-term management of pain and disability in patients with knee OA.

    To assess the effectiveness of mindfulness-based stress reduction (MBSR) for chronic insomnia and combined depressive or anxiety symptoms of older adults aged 75 years and over. A randomized, controlled, single-blind clinical trial. Participants included 60 adults aged 75 years and over with chronic insomnia. Participants were randomly assigned to the eight-week MBSR group or the wait-list control group. Assessments using the Pittsburgh Sleep Quality Index (PSQI), Self-rating Anxiety Sale (SAS), and Geriatric Depression Scale (GDS) were taken at baseline and post-treatment. For each outcome measure, a repeated measures analysis of variance was used to detect changes across assessments. There was a significant time × group interaction for the PSQI global score (P = .006); the MBSR group had a decrease in the PSQI global score (Cohen׳s d = 1.12), while the control group did not (Cohen׳s d = -0.06). Among the PSQI components, there was a significant time × group interaction for daytime dysfunction (P = .048); Cohen׳s d of the MBSR group was 0.76, while Cohen׳s d of control group was -0.04. There was no significant time × group interaction for the SAS score (P = .116), while for the GDS there was a significant time × group interaction (P = .039); the Cohen׳s d value for the MBSR group was 1.20, and it was 0.12 for the control group. This study demonstrated that the MBSR program could be a beneficial treatment for chronic insomnia in adults aged 75 years and older. Copyright © 2015 Elsevier Inc. All rights reserved.

    Silicone toe separator is considered as a conservative treatment for hallux valgus. The prefabricated toe separator does not fit all. However, effectiveness in prescription of the custom-mold toe separator is still unknown. To investigate the effect of using a custom-mold room temperature vulcanizing silicone toe separator to decrease hallux valgus angle and hallux pain. The compliances, complications, and satisfactions of toe separator were also explored. A prospective, randomized single-blinded controlled trial. A total of 90 patients with a moderate degree of hallux valgus were enrolled in a study at the Foot Clinic, Siriraj Hospital, Thailand. Patients were randomized into two groups; the study group was prescribed a custom-mold room temperature vulcanizing silicone toe separator for 6 h per night for 12 months. Patients in both groups received proper foot care and shoes and were permitted to continue drug treatment. In total, 40 patients in the study group and 39 patients in the control group completed the study. The hallux valgus angle was obtained through radiographic measurement. At month 12, both groups had significant differences in mean hallux valgus angle with a decrease of 3.3° ± 2.4° for the study group and increase of 1.9° ± 1.9° for the control group. There were statistically significant differences of hallux valgus angle between the two groups ( p Hallux pain was decreased in the study group. A custom-mold room temperature vulcanizing silicone toe separator can decrease hallux valgus angle and pain with no serious complications. Clinical relevance The custom-mold room temperature vulcanizing silicone toe separator for treatment of hallux valgus reduces deformity and hallux pain.

    To study the effects of augmented exercise therapy time for arm rehabilitation as either Bobath therapy or the impairment-oriented training (Arm BASIS training) in stroke patients with arm severe paresis. Single blind, multicentre randomized control trial. Three inpatient neurorehabilitation centres. Sixty-two anterior circulation ischaemic stroke patients. Random assignment to three group: (A) no augmented exercise therapy time, (B) augmented exercise therapy time as Bobath therapy and (C) augmented exercise therapy time as Arm BASIS training. Fugl-Meyer arm motor score. Secondary measure: Action Research Arm Test (ARA). Ancillary measures: Fugl-Meyer arm sensation and joint motion/pain scores and the Ashworth Scale (elbow flexors). An overall effect of augmented exercise therapy time on Fugl-Meyer scores after four weeks was not corroborated (mean and 95% confidence interval (CI) of change scores: no augmented exercise therapy time (n=20) 8.8, 5.2-12.3; augmented exercise therapy time (n=40) 9.9, 6.8-13.9; p = 0.2657). The group who received the augmented exercise therapy time as Arm BASIS training (n=20) had, however, higher gains than the group receiving the augmented exercise therapy time as Bobath therapy (n=20) (mean and 95% CI of change scores: Bobath 7.2, 2.6-11.8; BASIS 12.6, 8.4-16.8; p = 0.0432). Passive joint motion/pain deteriorated less in the group who received BASIS training (mean and 95% CI of change scores: Bobath -3.2, -5.2 to -1.1; BASIS 0.1, -1.8-2.0; p = 0.0090). ARA, Fugl-Meyer arm sensation, and Ashworth Scale scores were not differentially affected. The augmented exercise therapy time as Arm BASIS training enhanced selective motor control. Type of training was more relevant for recovery of motor control than therapeutic time spent.

    The effects of balneotherapy on chronic shoulder pain were studied. In this single-blind, randomized, follow-up study involving 46 patients with chronic shoulder pain, one group of patients received physiotherapy--exercise and transcutaneous electrical nerve stimulation--and the other group received balneotherapy in addition to physiotherapy for 4 weeks on 15 occasions. The following parameters were recorded before treatment (at week 0) and after treatment (at weeks 4, 7, and 13): Shoulder Pain and Disability Index (SPADI), the Short Form (36) Health Survey (SF-36) and EuroQuol-5D (EQ-5D) quality of life questionnaires, pain at rest and on movement on the visual analog scale (VAS), and active and passive range of motion. The SPADI pain, function, and total scores and the VAS scores at rest and on movement significantly improved in both groups after treatments. A greater improvement was observed in the balneotherapy group compared to the control group; regarding some parameters (VAS score on movement and SPADI function score at visit 2; VAS score at rest at visits 3 and 4), the difference between the groups was significant. The improvement of SF-36 and EQ-5D quality of life scores and the active range of motion was more pronounced in the balneotherapy group, the difference between the groups was not significant, except for EQ-5D at visit 2. Improvement of passive range of motion was not significant. Balneotherapy may have a beneficial effect on the clinical parameters and quality of life of patients with chronic shoulder pain. The number of patients should be increased.

    Full Text Available Abstract Background About 30-60% of individuals are non-adherent to their prescribed medications and this risk increases as the number of prescribed medications increases. This paper outlines the development of a consumer-centred Medicine Self-Management Intervention (MESMI, designed to improve blood pressure control and medication adherence in consumers with diabetes and chronic kidney disease recruited from specialist outpatients' clinics. Methods We developed a multifactorial intervention consisting of Self Blood Pressure Monitoring (SBPM, medication review, a twenty-minute interactive Digital Versatile Disc (DVD, and follow-up support telephone calls to help consumers improve their blood pressure control and take their medications as prescribed. The intervention is novel in that it has been developed from analysis of consumer and health professional views, and includes consumer video exemplars in the DVD. The primary outcome measure was a drop of 3-6 mmHg systolic blood pressure at three months after completion of the intervention. Secondary outcome measures included: assessment of medication adherence, medication self-efficacy and general wellbeing. Consumers' adherence to their prescribed medications was measured by manual pill count, self-report of medication adherence, and surrogate biochemical markers of disease control. Discussion The management of complex health problems is an increasing component of health care practice, and requires interventions that improve patient outcomes. We describe the preparatory work and baseline data of a single blind, randomized controlled trial involving consumers requiring cross-specialty care with a follow-up period extending to 12 months post-baseline. Trial Registration The trial was registered with the Australian and New Zealand Clinical Trials Register (ACTRN12607000044426.

    Shigellae cause severe disease in endemic countries, especially in children. Several efficacy trials have been conducted with candidate vaccines against Shigellae, but the lack of protection, the safety concerns, or manufacturing challenges hindered successful market approval. Conjugated vaccines have been shown to be safe and effective for different pathogens (i.e., Neisseria meningitidis, Shigella pneumonia, Haemophilus influenzae). The bio-conjugation technology, exploited here for the Shigella dysenteriae candidate vaccine, offers a novel and potentially simpler way to develop and produce vaccines against one of the major causes of morbidity and mortality in developing countries. A novel S. dysenteriae bioconjugate vaccine (GVXN SD133) made of the polysaccharide component of the Shigella O1 lipopolysaccharide, conjugated to the exotoxin protein A of Pseudomonas aeruginosa (EPA), was evaluated for immunogenicity and safety in healthy adults in a single blind, partially randomized Phase I study. Forty subjects (10 in each dose group; 2 μg or 10 μg with or without aluminium adjuvant) received two injections 60 days apart and were followed-up for 150 days. Both doses and formulations were well tolerated; the safety and reactogenicity profiles were consistent with that of other conjugated vaccines, adjuvanted or not, independent of the dose and the number of injections. The GVXN SD133 vaccine elicited statistically significant O1 specific humoral responses at all time points in all vaccination groups. Between-group comparisons did not show statistically significant differences in geometric mean titers of immunoglobulin G and A at any post-vaccination time point. This study demonstrated that the GVXN SD133 vaccine has a satisfactory safety profile. It elicited a significant humoral response to Shigella O1 polysaccharides at all doses tested.

    We assessed the effect of automated treatment adherence support delivered via mobile phone short message system (SMS) text messages on blood pressure. In this pragmatic, single-blind, 3-arm, randomized trial (SMS-Text Adherence Support [StAR]) undertaken in South Africa, patients treated for high blood pressure were randomly allocated in a 1:1:1 ratio to information only, interactive SMS text messaging, or usual care. The primary outcome was change in systolic blood pressure at 12 months from baseline measured with a validated oscillometric device. All trial staff were masked to treatment allocation. Analyses were intention to treat. Between June 26, 2012, and November 23, 2012, 1372 participants were randomized to receive information-only SMS text messages (n=457), interactive SMS text messages (n=458), or usual care (n=457). Primary outcome data were available for 1256 participants (92%). At 12 months, the mean adjusted change in systolic blood pressure compared with usual care was -2.2 mm Hg (95% confidence interval, -4.4 to -0.04) with information-only SMS and -1.6 mm Hg (95% confidence interval, -3.7 to 0.6) with interactive SMS. Odds ratios for the proportion of participants with a blood pressure high blood pressure, we found a small reduction in systolic blood pressure control compared with usual care at 12 months. There was no evidence that an interactive intervention increased this effect. URL: http://www.clinicaltrials.gov. Unique identifier: NCT02019823.

    Full Text Available Context: ProSeal Laryngeal Mask Airway (PLMA is extensively being used in pediatric anesthesia. Aims: To evaluate the efficacy of PLMA as compared to Classic Laryngeal Mask Airway (CLMA for airway maintenance in pediatric patients. Settings and Design: A prospective, randomized, Single-blinded study was conducted in a tertiary care teaching hospital. Materials and Methods: Sixty ASA I and II children were included. Patients were randomized to either size 2 PLMA or size 2 CLMA groups. Parameters noted were time for insertion, number of attempts, airway sealing pressure, blood pressures (systolic, diastolic, and mean, pulse rate, end-tidal carbon dioxide (EtCO 2 , peripheral oxygen saturation (SpO 2 , and postoperative change in abdominal circumference, and airway trauma. Statistical analysis used: Parametric data were analyzed with the unpaired t-test and non-parametric data were analyzed with the chi-square (c2 test. Unless otherwise stated, data are presented as mean (SD. Significance was taken as P < 0.05. Results: There was no statistical difference between the two groups for the success rates at the first attempt of insertion, airway sealing pressure, hemodynamic responses, SpO 2, EtCO 2 and postoperative changes in abdominal circumference. Patients in the PLMA group had longer time of insertion and higher incidence of airway trauma. Conclusions: The PLMA and the CLMA were comparable for hemodynamic and ventilatory parameters and change in abdominal circumference; however, the time taken for insertion and airway trauma was more with PLMA.

    Background: Psychological distress, biomedical parameters, and unhealthy lifestyles contribute to a poorer prognosis for cardiac disease. Public health's challenge is to motivate patients to utilize self-care. Objective: This prospective, randomized, single-blind pilot study aimed at testing the incremental efficacy of Brief Strategic Therapy (BST) combined with Motivational Interviewing (MI) in improving selected biomedical and psychological outcomes over and beyond those of the stand-alone BST in a residential Cardiac Rehabilitation (CR) program. Method: Fourty-two inpatients (17 females), enrolled in a 1-month CR program, were randomly allocated into two conditions: (a) Three sessions of BST and (b) Three sessions of BST plus MI. Data were collected at baseline, discharge, and after 3 months through phone interviews. Results: At discharge, no significant between-group difference was found in any outcome variable. Changes from pre- to post-treatment within each condition showed significant improvements only in the BST group, where the level of external regulation diminished, and both the participants' self-regulation (Relative Autonomous Motivation Index, RAI) and willingness to change improved. At the 3-month follow-up, within-group analyses on responders (BST = 9; BST + MI = 11) showed a statistically significant improvement in the level of systolic blood pressure in both groups. Discussion: Findings showed no evidence of the incremental efficacy of combining BST and MI over and beyond BST alone on either selected biomedical or psychological outcomes among CR patients. Conclusions: Ends and limitations from the present pilot study should be considered and addressed in future investigations. PMID:28223950

    Consumption of dietary carotenoids from fruits and vegetables (F/V) leads to accumulations in human skin, altering skin yellowness. The influence of the quantity of F/V consumed on skin yellowness and plasma carotenoid concentrations has not been examined previously. To compare the influence of consuming high-carotenoid-containing F/V (HCFV) (176,425 μg beta carotene/wk) vs low-carotenoid F/V (LCFV) (2,073 μg beta carotene/wk) on skin yellowness and plasma carotenoid concentrations, over 4 weeks. A single-blind randomized controlled crossover trial from October 2013 to March 2014. Thirty women were randomized to receive 7 daily servings of HCFV or LCFV for 4 weeks. Following a 2-week washout period they followed the alternate intervention. Skin color (Commission Internationale de l'Eclairage L*a*b* color space, where L* represents skin lightness and positive values of a* and b* represent degrees of redness and yellowness, respectively) was assessed by reflectance spectroscopy in both sun-exposed and nonexposed skin areas. Fasting plasma carotenoids were determined by high-performance liquid chromatography, before and after each intervention period. Linear mixed models were used to determine the HCFV and LCFV response on skin color and plasma carotenoids, adjusting for intervention order, time, and interaction between baseline differences and time. There were no significant differences in mean daily fruit (P=0.42) and vegetable (P=0.17) intakes between HCFV and LCFV groups. Dietary alpha carotene, beta carotene, lutein, and beta cryptoxanthin intakes were significantly different between the two groups (Pcarotenoid concentrations were significantly higher following HCFV than LCFV over 4 weeks.

    Full Text Available Chronic fatigue syndrome (CFS is a disease of unknown aetiology. Major CFS symptom relief during cancer chemotherapy in a patient with synchronous CFS and lymphoma spurred a pilot study of B-lymphocyte depletion using the anti-CD20 antibody Rituximab, which demonstrated significant clinical response in three CFS patients.In this double-blind, placebo-controlled phase II study (NCT00848692, 30 CFS patients were randomised to either Rituximab 500 mg/m(2 or saline, given twice two weeks apart, with follow-up for 12 months. Xenotropic murine leukemia virus-related virus (XMRV was not detected in any of the patients. The responses generally affected all CFS symptoms. Major or moderate overall response, defined as lasting improvements in self-reported Fatigue score during follow-up, was seen in 10 out of 15 patients (67% in the Rituximab group and in two out of 15 patients (13% in the Placebo group (p = 0.003. Mean response duration within the follow-up period for the 10 responders to Rituximab was 25 weeks (range 8-44. Four Rituximab patients had clinical response durations past the study period. General linear models for repeated measures of Fatigue scores during follow-up showed a significant interaction between time and intervention group (p = 0.018 for self-reported, and p = 0.024 for physician-assessed, with differences between the Rituximab and Placebo groups between 6-10 months after intervention. The primary end-point, defined as effect on self-reported Fatigue score 3 months after intervention, was negative. There were no serious adverse events. Two patients in the Rituximab group with pre-existing psoriasis experienced moderate psoriasis worsening.The delayed responses starting from 2-7 months after Rituximab treatment, in spite of rapid B-cell depletion, suggests that CFS is an autoimmune disease and may be consistent with the gradual elimination of autoantibodies preceding clinical responses. The present findings will impact

    Full Text Available Abstract Objective To evaluate the effectiveness and safety of polyunsaturated fatty acids for the treatment of the premenstrual syndrome (PMS using a graded symptom scale and to assess the effect of this treatment on basal plasma levels of prolactin and total cholesterol. Methods A randomized, double-blind, placebo-controlled study was conducted with 120 women with PMS divided into three groups and treated with 1 or 2 grams of the medication or placebo. Symptoms were recorded over a 6-month period using the Prospective Record of the Impact and Severity of Menstruation (PRISM calendar. Total cholesterol and prolactin levels were measured. Analysis of variance (ANOVA, Pearson's chi-square test, Wilcoxon's nonparametric signed-rank test for paired samples and the Mann-Whitney nonparametric test for independent samples were used in the statistical analysis. Results There were no differences in age, marital status, schooling or ethnicity between the groups. In the group treated with 1 gram of the medication, a significant reduction was found when the median PRISM score recorded in the luteal phase at baseline (99 was compared with the median score recorded in the 3rd month (58 and in the 6th month of evaluation (35. In the 2-gram group, these differences were even more significant (baseline score: 98; 3rd month: 48; 6th month: 28. In the placebo group, there was a significant reduction at the 3rd but not at the 6th month (baseline: 96.5; 3rd month: 63.5; 6th month: 62. The difference between the phases of the menstrual cycle was greater in the 2-gram group compared to the group treated with 1 gram of the medication. There were no statistically significant differences in prolactin or total cholesterol levels between baseline values and those recorded after six months of treatment. Conclusion The difference between the groups using the medication and the placebo group with respect to the improvement in symptomatology appears to indicate the

    The aim of the present study was to compare the effects of daily single-dose use of flurbiprofen, diclofenac sodium, and tenoxicam on pain, swelling, and trismus that occur after surgical extraction of impacted wisdom teeth using local anesthesia. The present study included 3 groups with 30 patients in each group. Those volunteering to participate in this double-blind randomized study (n = 90) were selected from a patient population with an indication for extraction of impacted wisdom teeth. Group 1 patients received 200 mg flurbiprofen, group 2 patients received 100 mg diclofenac sodium, and group 3 patients received 20 mg tenoxicam. All doses were once a day, starting preoperatively. Pain was evaluated postoperatively at 1, 2, 3, 6, 8, and 24 hours and at 2 and 7 days using a visual analog scale (VAS). For comparison with the preoperative measurements, the patients were invited to postoperative follow-up visits 2 and 7 days after extraction to evaluate for swelling and trismus. The statistical analysis was performed using descriptive statistics in SAS, version 9.4 (SAS Institute, Cary, NC), software. Statistical analysis of the pain, swelling, and trismus data was performed using the Kruskal-Wallis, Dunn, and Wilcoxon-Mann-Whitney U tests. The statistical level of significance was accepted at P = .05 and power of 0.80. Clinically, tenoxicam showed better analgesic and anti-inflammatory efficacy compared with diclofenac sodium and, in particular, flurbiprofen. Although the VAS scores in the evaluation of pain showed statistically significant differences at 2 days, no statistically significant difference was found for swelling and trismus. Our study evaluated the analgesic and anti-inflammatory effects with a daily single dose of flurbiprofen, diclofenac sodium, and tenoxicam. Daily 20 mg tenoxicam can be accepted as an adequate and safe option for patients after a surgical procedure. Copyright © 2016 American Association of Oral and Maxillofacial

    To demonstrate the pharmacokinetic/pharmacodynamic (PK/PD) equivalence of a biosimilar enoxaparin to the reference drug, and to assess its safety and tolerability in healthy volunteers. A randomized, double-blind, crossover, 2-sequence, single-dose study was conducted in healthy volunteers of both sexes. Participants were sequentially and randomly administered single subcutaneous injections of enoxaparin 100 mg manufactured by Rovi (test; Madrid, Spain) and Clexane ® (enoxaparin 100 mg manufactured by Sanofi, reference) separated by a 1-week washout period. The primary PK/PD variables were maximum activity (A max ) and area under the effect curve from time 0 to the last measured activity (T) (AUEC 0-T ) and AUEC from time 0 to infinity (AUEC 0-inf ) of anti-FXa activity, and A max and AUEC 0-T of anti-FIIa activity. Secondary variables were A max and AUEC 0-T , AUEC 0-inf of tissue factor pathway inhibitor, and the ratio of AUEC 0-T anti-FXa to anti-FIIa activity. Biosimilarity would be shown when the 95% CI of the ratio of geometric least squares means (95% CI RGLSMs) of primary PK/PD parameters fell within the standard range of bioequivalence, ie, 80%-125%. The study sample consisted of 46 volunteers (33 males) aged 18-44 years and with body mass index ranging from 19.0 to 31.1 kg/m 2 . Three subjects did not complete the study. The curves of anti-FXa, anti-FIIa and tissue factor pathway inhibitor activities corresponding to administration of the test and reference products were comparable. The 95% CI RGLSMs of A max , AUEC 0-T and AUEC 0-inf for anti-FXa activity were 94.6%-105.9%, 99.8%-108.0% and 100.0%-108.6% respectively; A max and AUEC 0-T for anti-FIIa activity were 94.7%-112.6% and 90.9%-117.9% respectively. In addition, the 95% CI RGLSMs of all secondary variables fell within the range 80%-125%. The incidence and types of adverse events after administration of the test and reference drugs were similar. The results conclusively showed that the enoxaparin

    Single shot spinal anesthesia is used worldwide for hip fracture repair surgery in the elderly. Arterial hypotension is a frequent adverse effect. We hypothesized that lowering local anesthetics dose could decrease the incidence of arterial hypotension, while maintaining quality of surgical anesthesia. In a randomized double blinded study, 66 patients over the age of 65 years, with hip fracture needing surgical repair, were assigned to B0.5 group 7.5mg hyperbaric bupivacaine 5mg/ml (control group), and B0.25 group 3.75mg hyperbaric bupivacaine 2.5mg/ml (study group). Sensory and motor block level, and hemodynamic parameters including blood presure, heart rate and vasopressor dose administration were registered, along with rescue anesthesia needs, the feasibility of surgery, its duration, and regression time of sensory anesthesia to T12. After exclusions, 61 patients were included in the final analysis. Arterial hypotension incidence was lower in the B0.25 group (at the 5, 10, and 15min determinations), and a lower amount of vasopressor drugs was needed (mean accumulated ephedrine dose 1.6mg vs. 8.7mg in the B0.5 group, p<0.002). Sensory block regression time to T12 was shorter in the B0.25 group, mean 78.6±23.6 (95% CI 51.7-110.2)min vs. 125.5±37.9 (95% CI 101.7-169.4)min in the B0.5 group, p=0.033. All but one patient in the B0.25 group were operated on under the anesthetic procedure first intended. No rescue anesthesia was needed. Lowering bupivacaine dose for single shot spinal anesthesia for hip fracture repair surgery in elderly patients was effective in decreasing the occurrence of arterial hypotension and vasopressor use, while intraoperative quality remained.

    Full Text Available Abstract Tooth whitening represents perhaps the most common aesthetic procedure in dentistry worldwide. The efficacy of bleaching depends on three aspects: bleaching agent, bleaching method, and tooth color. Objective: This in vivo study aimed to examine whitening effects on frontal teeth of the upper and lower jaws using an over-the-counter (OTC non-hydrogen peroxide bleaching agent in comparison to a placebo after one single use. Material and methods: Forty subjects (25 female; 15 male participated in this double-blind randomized placebo-controlled trial. The subjects were randomly allocated to two groups (n=20. The test group received the OTC product (iWhite Instant and the placebo group received an identically composed product except for the active agents. Each subject was treated with a prefilled tray containing iWhite Instant or the placebo for 20 minutes. The tooth shade of the front teeth (upper and lower jaws was assessed before (E_0, immediately after (E_1 and 24 h after treatment (E_2, using a shade guide (VITA classical. Statistical testing was accomplished using the Mann-Whitney U test (p<0.001. The dropout rate was 0%. Results: There were no significant differences at E_0 between placebo and test groups regarding the tooth color. Differences in tooth color changes immediately after (ΔE1_0 and 24 h after treatment (ΔE2_0 were calculated for both groups. The mean values (standard deviations of tooth color changes for ΔE1_0 were 2.26 (0.92 in the test group and 0.01 (0.21 in the placebo group. The color changes for ΔE2_0 showed mean values of 2.15 (1.10 in the test group and 0.07 (0.35 in the placebo group. For ΔE1_0 and ΔE2_0 significant differences were found between the groups. Conclusion: In this short-term study, the results showed that a non-hydrogen peroxide bleaching agent has significant whitening effects immediately and 24 h after a single-use treatment.

  16. Optimal blind quantum computation.

    2013-12-06

    Blind quantum computation allows a client with limited quantum capabilities to interact with a remote quantum computer to perform an arbitrary quantum computation, while keeping the description of that computation hidden from the remote quantum computer. While a number of protocols have been proposed in recent years, little is currently understood about the resources necessary to accomplish the task. Here, we present general techniques for upper and lower bounding the quantum communication necessary to perform blind quantum computation, and use these techniques to establish concrete bounds for common choices of the client's quantum capabilities. Our results show that the universal blind quantum computation protocol of Broadbent, Fitzsimons, and Kashefi, comes within a factor of 8/3 of optimal when the client is restricted to preparing single qubits. However, we describe a generalization of this protocol which requires exponentially less quantum communication when the client has a more sophisticated device.

    To assess the efficacy and safety of sono-electro-magnetic therapy compared to placebo in men with refractory CPPS. In a randomized, placebo-controlled, double-blind single center trial, we assessed the effect of sono-electro-magnetic therapy in men with treatment refractory CPPS. Sixty male patients were randomly assigned to treatment with either sono-electro-magnetic (n = 30) or placebo therapy (n = 30) for 12 weeks. The primary outcome was a change in the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) from baseline to 12 weeks. The 12-week difference between sono-electro-magnetic and placebo therapy in changes of the NIH-CPSI total score was -3.1 points (95% CI -6.8 to 0.6, p = 0.11). In secondary comparisons of NIH-CPSI sub-scores, we found differences between groups most pronounced for the quality-of-life sub-score (difference at 12 weeks -1.6, 95% CI -2.8 to -0.4, p = 0.015). In stratified analyses, the benefit of sono-electro-magnetic therapy appeared more pronounced among patients who had a symptom duration of 12 months or less (difference in NIH-CPSI total score -8.3, 95% CI -14.5 to 2.6) than in patients with a longer symptom duration (-0.8, 95% CI -4.6 to 3.1; p for interaction = 0.023). Sono-electro-magnetic therapy did not result in a significant improvement of symptoms in the overall cohort of treatment refractory CPPS patients compared to placebo treatment. Subgroup analysis indicates, however, that patients with a symptom-duration of 12 months or less may benefit from sono-electro-magnetic therapy, warranting larger randomized controlled trials in this subpopulation.

    The effects of rebamipide on dry mouth and salivary secretion in Sjögren's syndrome patients were investigated in a double-blind placebo-controlled study. Rebamipide (100 mg TID) or placebo was administered for eight weeks and patient-assessed improvement of dry mouth and increase in salivary secretion measured by the Saxon test were evaluated. At two, four, and eight weeks, dry mouth improvement rates were, respectively, 26.0, 44.0, and 46.9% for rebamipide and 20.0, 27.1, and 39.1% for placebo, and mean increases in salivary secretion were, respectively, 0.14, 0.24, and 0.35 g for rebamipide and 0.03, 0.09, and 0.17 g for placebo, indicating higher values in the rebamipide group for both parameters at all timepoints but no significant differences between the two groups. Analysis by baseline characteristics suggested a statistically significant salivary secretion increasing effect of rebamipide in cases of primary Sjögren's syndrome. No difference in the incidence of adverse events was seen between the two groups, confirming the safety of rebamipide. As a salivary secretion increasing effect was strongly suggested in cases of primary Sjögren's syndrome, further study on the administration of rebamipide for the treatment of dry mouth in patients with Sjögren's syndrome is required.

    Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) corresponds to a rare and acute life-threatening mucocutaneous reactions characterized by extensive necrosis and epidermal detachment. There are no efficacious pharmaceutical interventions proven through large clinical trials. We sought to study clinical cases admitted in our institution in order to determine which drugs and medical comorbidities or treatments impacted the mortality. In a retrospective study over 9 years we evaluated all patients presenting biopsy-proven SJS or TEN for age, gender, total body surface area involved, causing agents, SCORTEN score, blood transfusion, steroid administration, intubation, length of intensive care stay and death rate. Statistical analysis was done using SPSS statistical software. The highest incidence of SJS and TEN was in age group of 71-80 years. Of the 30 patients, 30% died from SJS/TEN, mainly due sepsis. For each subgroup SJS/TEN overlap had the highest mortality. The highest mortality was from antibiotic treatment as causing agent. Step-wise regression analysis identified mechanical ventilation requirement and age over 65 years as mortality high-risk factors. The most crucial interventions are discontinuation of the offending drug and prompt referral to a burn unit, which helps in early diagnosis and decrease mortality in these diseases. When SJS/TEN is caused by antibiotics suspicion of developing fatal sepsis should be high, independently of patients' medical condition.

This was a phase 2, single-blind, randomised controlled trial done at the Clinical Research Centre of the Malaria Research and Training Centre (MRTC) of the University of Bamako (Bamako, Mali). We enrolled male participants aged 5-50 years with asymptomatic P falciparum malaria. G6PD-normal participants with gametocytes detected by blood smear were randomised 1:1:1:1 in block sizes of eight, using a sealed-envelope design, to receive either sulfadoxine-pyrimethamine and amodiaquine, sulfadoxine-pyrimethamine and amodiaquine plus a single dose of 0·25 mg/kg primaquine, dihydroartemisinin-piperaquine, or dihydroartemisinin-piperaquine plus 15 mg/kg per day methylene blue for 3 days. Laboratory staff, investigators, and insectary technicians were masked to the treatment group and gametocyte density of study participants. The study pharmacist and treating physician were not masked. Participants could request unmasking. The primary efficacy endpoint, analysed in all infected patients with at least one infectivity measure before and after treatment, was median within-person percentage change in mosquito infectivity 2 and 7 days after treatment, assessed by membrane feeding. This study is registered with ClinicalTrials.gov, number NCT02831023. Between June 27, 2016, and Nov 1, 2016, 80 participants were enrolled and assigned to the sulfadoxine-pyrimethamine and amodiaquine (n=20), sulfadoxine-pyrimethamine and amodiaquine plus primaquine (n=20), dihydroartemisinin-piperaquine (n=20), or dihydroartemisinin-piperaquine plus methylene blue (n=20) groups. Among participants infectious at baseline (54 [68%] of 80), those in the

    Rofecoxib and celecoxib, selective cyclooxygenase-2 inhibitors, have analgesic efficacy similar to that of nonselective nonsteroidal anti-inflammatory drugs. This study was designed to confirm earlier findings that the overall analgesic efficacy of rofecoxib 50 mg was superior to that of celecoxib 200 mg and to extend the comparison to include celecoxib 400 mg. In this single-center, randomized, double-blind, placebo- and active-comparator-controlled, parallel-group, single-dose study, patients who experienced moderate or severe pain after surgical extraction of at least 2 third molars received a single oral dose of either rofecoxib 50 mg, celecoxib 400 mg, celecoxib 200 mg, ibuprofen 400 mg, or placebo. Patients recorded scores of pain intensity, pain relief, and global assessment at prespecified time intervals throughout the 24-hour period after dosing. The end points were total pain relief (TOPAR) score over 8 hours (TOPAR8; primary end point), TOPAR score over 12 hours (TOPAR12), sum of pain intensity difference (SPID) over 8 and 12 hours (SPID8 and SPID12), patient's global assessment of study drug at 8 hours, time to confirmed perceptible pain relief (ie, time to onset of analgesic effect), peak pain intensity difference (PID), peak pain relief, time to first dose of rescue medication (ie, duration of analgesic effect), and percentage of patients using rescue medication. A total of 482 patients (358 females, 124 males; mean age, 22.1 years) were enrolled. Rofecoxib 50 mg (n = 151 patients) demonstrated significantly greater overall analgesic efficacy compared with celecoxib 400 mg (n = 151), as measured by TOPAR8 (least squares mean [SE] 17.2 [0.8] vs 15.0 [0.8]; P TOPAR12 (25.3 [1.2] vs 21.0 [1.2]; P TOPAR8 scores (17.2 [0.8] vs 11.5 [1.1]; P TOPAR8, TOPAR12, SPID8, SPID12, and patient's global assessment] for all study drugs). The adverse-events (AE) profile was generally similar in all treatment groups. The 3 most common AEs were nausea, postextraction

    Home ultraviolet B (UVB) treatment is a much-debated treatment, especially with regard to effectiveness, safety and side effects. However, it is increasingly being prescribed, especially in the Netherlands. Despite ongoing discussions, no randomised research has been performed, and only two studies actually compare two groups of patients. Thus, firm evidence to support or discourage the use of home UVB phototherapy has not yet been obtained. This is the goal of the present study, the PLUTO study (Dutch acronym for "national trial on home UVB phototherapy for psoriasis"). We designed a pragmatic randomised single-blind multi-centre trial. This trial is designed to evaluate the impact of home UVB treatment versus UVB phototherapy in a hospital outpatient clinic as to effectiveness, quality of life and cost-effectiveness. In total 196 patients with psoriasis who were clinically eligible for UVB phototherapy were included. Normally 85% of the patients treated with UVB show a relevant clinical response. With a power of 80% and a 0.05 significance level it will be possible to detect a reduction in effectiveness of 15%. Effectiveness will be determined by calculating differences in the Psoriasis Area and Severity Index (PASI) and the Self Administered PASI (SAPASI) scores. Quality of life is measured using several validated generic questionnaires and a disease-specific questionnaire. Other outcome measures include costs, side effects, dosimetry, concomitant use of medication and patient satisfaction. Patients are followed throughout the therapy and for 12 months thereafter. The study is no longer recruiting patients, and is expected to report in 2006. In the field of home UVB phototherapy this trial is the first randomised parallel group study. As such, this trial addresses the weaknesses encountered in previous studies. The pragmatic design ensures that the results can be well generalised to the target population. Because, in addition to effectiveness, aspects such as

    Full Text Available Abstract Background Depression is prevalent in people with type 2 diabetes and affects both glycemic control and overall quality of life. The aim of this trial was to evaluate the effect of the antidepressant paroxetine on metabolic control, quality of life and mental well-being in mildly depressed women with type 2 diabetes. Methods We randomised 15 mildly depressed women with non-optimally controlled type 2 diabetes to a 10-week single-blind treatment with either paroxetine 20 mg per day or placebo. Primary efficacy measurements were glycemic control and quality of life. Glycosylated hemoglobin A1c (GHbA1c was used as a measure of glycemic control. Quality of life was evaluated using RAND-36. Mental state was assessed using two clinician-rated scoring instruments, Hamilton's Anxiety Scale (HAM-A and Montgomery-Åsberg's Depression Rating Scale (MADRS, and a patient-rated scoring instrument, Beck's Depression Inventory (BDI. Results At the end of the study no significant difference between groups in improvement of quality of life was found. A trend towards a superior improvement in glycemic control was found in the paroxetine group (p = 0.08. A superior increase in sex-hormone-binding-globuline (SHBG levels was evidenced in the paroxetine group (p = 0.01 as a sign of improved insulin sensitivity. There was also a trend for superior efficacy of paroxetine in investigator-rated anxiety and depression. This notion was supported by a trend for superior decrease of serum cortisol levels in the paroxetine group (p = 0.06. Conclusion Paroxetine has a beneficial effect on measures of insulin sensitivity and may improve glycemic control. Larger studies of longer duration are needed to verify the benefits of paroxetine in type 2 diabetes. While waiting for more conclusive evidence it seems sensible to augment standard care of type 2 diabetes with paroxetine even in patients who do not fulfil routine psychiatric criteria for initiation of antidepressant

    Children living with foster families in a resource-limited setting such as Ethiopia are at risk of developmental problems. It is not yet clear whether intensive home-based developmental stimulation assisted by play can reduce these problems. The main objective of this study was to examine the effects of play-assisted intervention integrated into basic services on the developmental performance of children living with foster families in extreme poverty. A randomized single-blind (investigator) controlled trial design was used. The study was conducted in Jimma, South West Ethiopia. Using computer-generated codes, eligible children of 3-59 months in age were randomly allocated to intervention (n = 39) and control (n = 39) groups at a 1:1 ratio. Children in the intervention group received home-based play-assisted stimulation in addition to the basic services provided to children in both groups. The intervention consisted of an hour of play stimulation conducted during a weekly home visit over the course of six months. Personal-social, language, fine and gross motor outcomes were assessed using Denver II-Jimma, and social-emotional outcome was obtained using an adapted Ages and Stages Questionnaire: Social-Emotional (ASQ: SE). Information about sociodemographic characteristics was collected using a structured questionnaire. Anthropometric methods were used to determine nutritional status. The effects of the intervention on the abovementioned outcomes over the study period and group differences in change over time were examined using Generalized Estimating Equations (GEE). Statistically significant intervention effects were found for language (P = 0.0014), personal-social (P = 0.0087) and social-emotional (P size = 0.34) and social-emotional (effect size = - 0.603) benefits from the play-assisted stimulation had already been observed for the children in the intervention group. For language, the intervention effect depended on the child's sex

    There is evidence that animal-assisted therapy has positive effects on mental health, especially in elderly people. Caring for insects is easy, relatively inexpensive, and does not require much space. The aim of this 8-week randomized, controlled, single-blinded study was to investigate the effect of pet insects on the psychological health of community-dwelling elderly people. Elderly subjects (≥65 years old) attending a community center in Daegu, Korea, were enrolled in the study between April and May 2014 and randomized at a 1:1 ratio to receive insect therapy and health advice or only health advice. The insect group received 5 crickets in a cage with sufficient fodder and a detailed instruction manual. At baseline and at 8 weeks, all subjects underwent psychometric tests via a direct interview [Beck Anxiety Inventory, Geriatric Depression Scale (GDS-15), Mini-Mental State Examination (MMSE), 36-Item Short Form Health Survey, Insomnia Severity Index, Fatigue Severity Scale, and Brief Encounter Psychosocial Instrument] and laboratory analyses of inflammatory and oxidative stress markers (erythrocyte sedimentation rate, high-sensitivity C-reactive protein, biological antioxidant potential, and derivatives of reactive oxygen metabolites). The insect-caring (n = 46) and control (n = 48) groups did not differ in baseline characteristics. The insect-caring group had significantly lower GDS-15 scores at week 8 (3.20 vs. 4.90, p = 0.004) and, after adjustment for baseline values, a significantly greater change in GDS-15 scores relative to baseline (-1.12 vs. 0.20, p = 0.011). They also had a significantly greater change in MMSE scores relative to baseline (1.13 vs. 0.31, p = 0.045). The two groups did not differ in terms of other psychometric and laboratory tests. No serious risks or adverse events were reported. Caring for insects, which is cost-effective and safe, was associated with a small to medium positive effect on depression and cognitive function in community

    Since falls may lead to fractures and have serious, potentially fatal outcomes, prevention of falls is an urgent public health issue. We examined the effects of chair yoga therapy on physical fitness among psychiatric patients in order to reduce the risk of falls, which has not been previously reported in the literature. In this 12-week single-blind randomized controlled trial with a 6-week follow-up, inpatients with mixed psychiatric diagnoses were randomly assigned to either chair yoga therapy in addition to ongoing treatment, or treatment-as-usual. Chair yoga therapy was conducted as twice-weekly 20-min sessions over 12 weeks. Assessments included anteflexion in sitting, degree of muscle strength, and Modified Falls Efficacy Scale (MFES) as well as QOL, psychopathology and functioning. Fifty-six inpatients participated in this study (36 men; mean ± SD age, 55.3 ± 13.7 years; schizophrenia 87.5%). In the chair yoga group, significant improvements were observed in flexibility, hand-grip, lower limb muscle endurance, and MFES at week 12 (mean ± SD: 55.1 ± 16.6 to 67.2 ± 14.0 cm, 23.6 ± 10.6 to 26.8 ± 9.7 kg, 4.9 ± 4.0 to 7.0 ± 3.9 kg, and 114.9 ± 29.2 to 134.1 ± 11.6, respectively). Additionally, these improvements were observable six weeks after the intervention was over. The QOL-VAS improved in the intervention group while no differences were noted in psychopathology and functioning between the groups. The intervention appeared to be highly tolerable without any notable adverse effects. The results indicated sustainable effects of 20-min, 12-week, 24-session chair yoga therapy on physical fitness. Chair yoga therapy may contribute to reduce the risk of falls and their unwanted consequences in psychiatric patients. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available Tourette’s syndrome (TS is a neurodevelopmental disorder typically defined by multiple motor tics and at least one sound tic (1, beginning in childhood or in adolescence. More recently, Tourette’s syndrome has been acknowledged as a broad spectrum syndrome (2, including different comorbidities and coexisting symptoms. When beginning in early childhood TS mainly presents with attention deficit and hyperactivity disorder (ADHD and tics, when beginning in adolescence instead tics and obsessive-compulsive behavior or disorder (OCB/OCD are predominant. OCB/OCD trait is present in 60-80% of patients (3, and they are considered as thought tics (4. In many cases motor and sound tics resolve spontaneously in adulthood, though OCB/OCD generally remain. Tics often interfere with subject’s daily activities (5 affecting Quality of Life and causing Social Impairment, particularly in schooling and working. Handwriting is one of the most impaired school activity for TS patients because of the tics presence that hamper learning processes.In our clinical experience handwriting tics (HT could severely affect and condition TS subjects, but they are not often pointed out in the Literature. For this reason there are not precise data regarding the incidence of HT neither in Tourette’s syndrome patients nor in healthy population.

    Colonic pseudo obstruction disease commonly seen in the elderly, immobile patient group can cause serious mortality and morbidity. Our objective in this retrospective study is to share our clinical experience by evaluating patients with Ogilvie syndrome who were followed and treated in our clinic. Eleven cases with the diagnosis of Ogilvie syndrome followed up and treated between September 2010 and April 2013 were evaluated retrospectively. All the patients that had no symptoms of acute abdominal pain were initiated conservative treatment. Colonoscopic decompression was attempted for patients whose clinical pictures were not recovered. Patients underwent operation if they developed peritoneal irritation symptoms during these procedures and of their number of white blood cells seriously increased during the follow-up period. A total of 11 patients were treated for Ogilvie syndrome. 6 of the patients underwent surgical treatment, and 5 were treated medically. Mortality developed in two patients. The main cause of mortality was a delay in diagnosis and additional severe underlying diseases. Seven patients were given Neostigmine. Of these, 2 patients required surgery and 3 patients responded to Neostigmine. Ogilvie syndrome is a rare cause of ileus of the colon. It is more common particularly in old patients with additional problems. If the disease is suspected and diagnosed early, unnecessary surgical interventions can be prevented with medical treatment choices.

    To analyze the rate of postoperative infection and nonunion after tibial fractures in patients treated for acute compartment syndrome (ACS) using (1) single-incision versus (2) dual-incision fasciotomy technique. Retrospective. Level I trauma center. Review of all adult tibial fractures operatively treated (n = 2756) over a 12-year period identified 175 patients with concurrent ACS requiring fasciotomy. Of 60 patients treated with intramedullary nails, 36 patients had single-incision fasciotomy and 24 had dual-incision fasciotomy. Of 81 patients treated with plate fixation, 59 patients had single-incision fasciotomy and 22 had dual-incision fasciotomy. Tibial fixation with fasciotomy for ACS. Occurrence of postoperative infection and nonunion. Both fasciotomy groups were similar across recorded patient and treatment characteristics. Need for skin graft was similar between fasciotomy groups. For patients treated with intramedullary nail (n = 60), 1 infection (2.8%) occurred in single-incision group versus 2 (8.3%) in dual-incision group (P = 0.558). Seven nonunions (19.4%) occurred in single-incision group versus 3 (12.5%) in dual-incision group (P = 0.726). For plate fixation patients (n = 81), 15 infections (25.4%) occurred with single-incision fasciotomy versus 5 infections (22.7%) with dual-incision fasciotomy (P = 1.000). Seven nonunions (11.9%) occurred with single-incision group versus 4 nonunions (18.2%) with dual-incision group (P = 0.479). This is the first study to compare a single-incision fasciotomy technique to a dual-incision technique in the setting of tibial fractures with ACS, with similar infection and nonunion rates with either technique. The choice of fasciotomy technique can be based on surgeon experience or patient condition as opposed to a suspected elevated infection or nonunion risk with either technique. Therapeutic Level III.

    Full Text Available Genetic diagnosis of inherited metabolic disease is conventionally achieved through syndrome recognition and targeted gene sequencing, but many patients receive no specific diagnosis. Next generation sequencing allied to capture of expressed sequences from genomic DNA now offers a powerful new diagnostic approach. Barriers to routine diagnostic use include cost, and the complexity of interpreting results arising from simultaneous identification of large numbers of variants. We applied exome-wide sequencing to an individual, 16 year old daughter of consanguineous parents with a novel syndrome of short stature, severe insulin resistance, ptosis and microcephaly. Pulldown of expressed sequences from genomic DNA followed by massively parallel sequencing was undertaken. Single nucleotide variants (SNVs were called using SAMtools prior to filtering based on sequence quality and existence in control genomes and exomes. Of 485 genetic variants predicted to alter protein sequence and absent from control data, 24 were homozygous in the patient. One mutation – the p.Arg732X mutation in the WRN gene – has previously been reported in Werner’s syndrome (WS. On re-evaluation of the patient several early features of WS were detected including loss of fat from the extremities and frontal hair thinning. Lymphoblastoid cells from the proband exhibited a defective decatenation checkpoint, consistent with loss of WRN activity. We have thus diagnosed WS some 15 years earlier than average, permitting aggressive prophylactic therapy and screening for WS complications, illustrating the potential of exome-wide sequencing to achieve early diagnosis and change management of rare autosomal recessive disease, even in individual patients of consanguineous parentage with apparently novel syndromes.

    Skin abscesses are a frequent encountered health care problem and lead to a significant source of morbidity. They consequently have an essential impact on the quality of life and work. To date, the type of aftercare for surgically drained abscesses remains under debate. This leads to undesirable practice variations. Many clinical standard protocols include sterile wound dressings twice a day by a home-care service to reduce the chance of a recurrent wound infection. It is unknown, however, whether reinfection rates are comparable to adequate wound irrigation with a nonsterile solution performed by the patient. Our hypothesis is that simple wound irrigation with nonsterile water for postoperative wound care after an abscess is surgically drained is feasible. We assume that in terms of reinfection and reintervention rates unsterile wound irrigation is equal to sterile wound irrigation. The primary aim of this study is therefore to investigate if there is a need for sterile wound irrigation after surgically drained spontaneous skin abscesses. In a prospective, randomized controlled, single-blinded, single-center trial based on a noninferiority design, we will enroll 128 patients randomized to either the control or the intervention group. The control group will be treated according to our current, standard protocol in which all patients receive a sterile wound irrigation performed by a home-care service twice a day. Patients randomized to the intervention group will be treated with a nonsterile wound irrigation (shower) twice a day. All patients will have a routine clinical control visit after 1, 3, 6, and 12 weeks in the outpatient clinic. Primary outcome is the reinfection and reoperation rate due to insufficient wound healing diagnosed either at the outpatient control visit or during general practitioner visits. Secondary outcome measures include a Short Form Health Survey, Visual Analog Scale, Patient and Observer Scar Assessment Scale, Vancouver Scar Scale, and

    Background: Vitamin E supplementation improves liver histology in patients with nonalcoholic steatohepatitis, which is a manifestation of the metabolic syndrome (MetS). We reported previously that α-tocopherol bioavailability in healthy adults is higher than in those with MetS, thereby suggesting that the latter group has increased requirements. Objective: We hypothesized that α-tocopherol catabolites α-carboxyethyl hydroxychromanol (α-CEHC) and α-carboxymethylbutyl hydroxychromanol (α-CMBHC) are useful biomarkers of α-tocopherol status. Design: Adults (healthy or with MetS; n = 10/group) completed a double-blind, crossover clinical trial with four 72-h interventions during which they co-ingested 15 mg hexadeuterium-labeled RRR -α-tocopherol (d 6 -α-T) with nonfat, reduced-fat, whole, or soy milk. During each intervention, we measured α-CEHC and α-CMBHC excretions in three 8-h urine collections (0-24 h) and plasma α-tocopherol, α-CEHC, and α-CMBHC concentrations at various times ≤72 h. Results: During the first 24 h, participants with MetS compared with healthy adults excreted 41% less α-CEHC (all values are least-squares means ± SEMs: 0.6 ± 0.1 compared with 1.0 ± 0.1 μmol/g creatinine, respectively; P = 0.002), 63% less hexadeuterium-labeled (d 6 )-α-CEHC (0.04 ± 0.02 compared with 0.13 ± 0.02 μmol/g creatinine, respectively; P = 0.002), and 58% less d 6 -α-CMBHC (0.017 ± 0.004 compared with 0.041 ± 0.004 μmol/g creatinine, respectively; P = 0.0009) and had 52% lower plasma d 6 -α-CEHC areas under the concentration curves [area under the curve from 0 to 24 h (AUC 0-24h ): 27.7 ± 7.9 compared with 58.4 ± 7.9 nmol/L × h, respectively; P = 0.01]. d 6 -α-CEHC peaked before d 6 -α-T in 77 of 80 paired plasma concentration curves.

    Background: Vitamin E supplementation improves liver histology in patients with nonalcoholic steatohepatitis, which is a manifestation of the metabolic syndrome (MetS). We reported previously that α-tocopherol bioavailability in healthy adults is higher than in those with MetS, thereby suggesting that the latter group has increased requirements. Objective: We hypothesized that α-tocopherol catabolites α-carboxyethyl hydroxychromanol (α-CEHC) and α-carboxymethylbutyl hydroxychromanol (α-CMBHC) are useful biomarkers of α-tocopherol status. Design: Adults (healthy or with MetS; n = 10/group) completed a double-blind, crossover clinical trial with four 72-h interventions during which they co-ingested 15 mg hexadeuterium-labeled RRR-α-tocopherol (d6-α-T) with nonfat, reduced-fat, whole, or soy milk. During each intervention, we measured α-CEHC and α-CMBHC excretions in three 8-h urine collections (0–24 h) and plasma α-tocopherol, α-CEHC, and α-CMBHC concentrations at various times ≤72 h. Results: During the first 24 h, participants with MetS compared with healthy adults excreted 41% less α-CEHC (all values are least-squares means ± SEMs: 0.6 ± 0.1 compared with 1.0 ± 0.1 μmol/g creatinine, respectively; P = 0.002), 63% less hexadeuterium-labeled (d6)-α-CEHC (0.04 ± 0.02 compared with 0.13 ± 0.02 μmol/g creatinine, respectively; P = 0.002), and 58% less d6-α-CMBHC (0.017 ± 0.004 compared with 0.041 ± 0.004 μmol/g creatinine, respectively; P = 0.0009) and had 52% lower plasma d6-α-CEHC areas under the concentration curves [area under the curve from 0 to 24 h (AUC0–24h): 27.7 ± 7.9 compared with 58.4 ± 7.9 nmol/L × h, respectively; P = 0.01]. d6-α-CEHC peaked before d6-α-T in 77 of 80 paired plasma concentration curves. Urinary d6-α-CEHC 24-h concentrations were associated with the plasma AUC0–24 h of d6-α-T (r = 0.53, P = 0.02) and d6-α-CEHC (r = 0.72, P = 0.0003), and with urinary d6-α-CMBHC (r = 0.88, P < 0.0001), and

    Data on the effects of synbiotic supplementation on glycemic control, lipid profiles, and atherogenic index of plasma (AIP) of women with polycystic ovary syndrome (PCOS) are limited. The purpose of this study was to assess the effects of synbiotic supplementation on glycemic control and lipid profiles in women with PCOS. A prospective, randomized, double-blind, placebo-controlled trial was done at the Naghavi Hospital affiliated to Kashan University of Medical Sciences, Kashan, Iran, between April 2017 and June 2017. Sixty women with PCOS were randomized to intake synbiotic capsule containing Lactobacillus acidophilus strain T16 (IBRC-M10785), Lactobacillus casei strain T2 (IBRC-M10783), and Bifidobacterium bifidum strain T1 (IBRC-M10771) (2 × 10 9  CFU/g each) plus 800 mg inulin (n = 30) or placebo (n = 30) for 12 weeks. Fasting blood samples were taken at baseline and after the 12-week intervention to determine related variables. Compared with the placebo, synbiotic supplementation resulted in a significant reduction in serum insulin concentrations (- 2.8 ± 4.1 vs. + 1.8 ± 6.4 μIU/mL, P = 0.002) and homeostasis model of assessment-insulin resistance (- 0.7 ± 1.0 vs. + 0.4 ± 1.5, P = 0.002), and a significant elevation in the quantitative insulin sensitivity check index (+ 0.01 ± 0.01 vs. - 0.01 ± 0.03, P < 0.001). In addition, significant decreases in serum triglycerides (- 16.2 ± 31.4 vs. + 5.8 ± 23.1 mg/dL, P = 0.003), VLDL-cholesterol concentrations (- 3.3 ± 6.3 vs. + 1.1 ± 4.6 mg/dL, P = 0.003), and AIP (- 0.05 ± 0.08 vs. - 0.003 ± 0.10 mg/dL, P = 0.03) were seen following the supplementation of synbiotic compared with the placebo. Overall, we found that synbiotic supplementation to women with PCOS for 12 weeks had beneficial effects on markers of insulin resistance, triglycerides, VLDL-cholesterol concentrations, and AIP, but did

    Full Text Available OBJECTIVE: To assess the efficacy and safety of sono-electro-magnetic therapy compared to placebo in men with refractory CPPS. PATIENTS AND METHODS: In a randomized, placebo-controlled, double-blind single center trial, we assessed the effect of sono-electro-magnetic therapy in men with treatment refractory CPPS. Sixty male patients were randomly assigned to treatment with either sono-electro-magnetic (n = 30 or placebo therapy (n = 30 for 12 weeks. The primary outcome was a change in the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI from baseline to 12 weeks. RESULTS: The 12-week difference between sono-electro-magnetic and placebo therapy in changes of the NIH-CPSI total score was -3.1 points (95% CI -6.8 to 0.6, p = 0.11. In secondary comparisons of NIH-CPSI sub-scores, we found differences between groups most pronounced for the quality-of-life sub-score (difference at 12 weeks -1.6, 95% CI -2.8 to -0.4, p = 0.015. In stratified analyses, the benefit of sono-electro-magnetic therapy appeared more pronounced among patients who had a symptom duration of 12 months or less (difference in NIH-CPSI total score -8.3, 95% CI -14.5 to 2.6 than in patients with a longer symptom duration (-0.8, 95% CI -4.6 to 3.1; p for interaction = 0.023. CONCLUSIONS: Sono-electro-magnetic therapy did not result in a significant improvement of symptoms in the overall cohort of treatment refractory CPPS patients compared to placebo treatment. Subgroup analysis indicates, however, that patients with a symptom-duration of 12 months or less may benefit from sono-electro-magnetic therapy, warranting larger randomized controlled trials in this subpopulation.

    Treacher Collins syndrome (TCS) is a rare craniofacial disorder characterized by facial anomalies and ear defects. TCS is caused by mutations in the TCOF1 gene and follows autosomal dominant inheritance. Recently, mutations in the POLR1D and POLR1C genes have also been identified to cause TCS. However, in a subset of patients no causative mutation could be found yet. Inter- and intrafamilial phenotypic variability is high as is the variety of mainly family-specific mutations identified throug...

    Nurses' lack of readiness for evidence-based practice slows down the uptake, adoption, and implementation of evidence-based practice which is of international concern as it impedes attainment of the highest quality of care and best patient outcomes. There is limited evidence about the most effective approaches to strengthen nurses' readiness for evidence-based practice. To evaluate the effectiveness of an Advanced Practice Nurse-delivered education program to strengthen nurses' readiness for evidence-based practice at a university hospital. A single-blind randomized controlled trial with repeated measures design, with measures completed during spring and fall 2015, before the education program (T0), within 1week after (T1), 8weeks after (T2), and 4months after completion of education interventions (T3). One large university hospital system in Finland, consisting of 15 acute care hospitals. The required sample size, calculated by a priori power analysis and including a 20% estimated attrition rate, called for 85 nurse participants to be recruited. Nurses working in different professional nursing roles and care settings were randomly allocated into two groups: intervention (evidence-based practice education, N=43) and control (research utilization education, N=34). The nurse participants received live 4-h education sessions on the basic principles of evidence-based practice (intervention group) and on the principles of research utilization (control group). The intervention group also received a web-based interactive evidence-based practice education module with a booster mentoring intervention. Readiness for evidence-based practice data, previous experience with evidence-based practice, and participant demographics were collected using the Stevens' EBP Readiness Inventory. Nurses' confidence in employing evidence-based practice and actual evidence-based practice knowledge were lower at T0, compared with the post-education scores, specifically at T1. The improvement

    Objective To compare the effect of pelvic floor exercises, electrical stimulation, vaginal cones, and no treatment for genuine stress incontinence. Design Stratified, single blind, randomised controlled trial. Setting Multicentre. Participants 107 women with clinically and urodynamically proved genuine stress incontinence. Mean (range) age was 49.5 (24-70) years, and mean (range) duration of symptoms 10.8 (1-45) years. Interventions Pelvic floor exercise (n=25) comprised 8-12 contractions 3 times a day and exercise in groups with skilled physical therapists once a week. The electrical stimulation group (n=25) used vaginal intermittent stimulation with the MS 106 Twin at 50 Hz 30 minutes a day. The vaginal cones group (n=27) used cones for 20 minutes a day. The untreated control group (n=30) was offered the use of a continence guard. Muscle strength was measured by vaginal squeeze pressure once a month. Main outcome measures Pad test with standardised bladder volume, and self report of severity. Results Improvement in muscle strength was significantly greater (P=0.03) after pelvic floor exercises (11.0 cm H2O (95% confidence interval 7.7 to 14.3) before v 19.2 cm H2O (15.3 to 23.1) after) than either electrical stimulation (14.8 cm H2O (10.9 to 18.7) v 18.6 cm H2O (13.3 to 23.9)) or vaginal cones (11.8 cm H2O (8.5 to 15.1) v 15.4 cm H2O (11.1 to 19.7)). Reduction in leakage on pad test was greater in the exercise group (−30.2 g; −43.3 to 16.9) than in the electrical stimulation group (−7.4 g; −20.9 to 6.1) and the vaginal cones group (−14.7 g; −27.6 to −1.8). On completion of the trial one participant in the control group, 14 in the pelvic floor exercise group, three in the electrical stimulation group, and two in the vaginal cones group no longer considered themselves as having a problem. Conclusion Training of the pelvic floor muscles is superior to electrical stimulation and vaginal cones in the treatment of genuine stress

    Full Text Available Abstract Background Current evidence on electrotherapies for the management of chronic neck pain is either lacking or conflicting. New therapeutic devices being introduced to the market should be investigated for their effectiveness and efficacy. The ENAR® (Electro Neuro Adaptive Regulator therapy device combines Western biofeedback with Eastern energy medicine. Methods A small, preliminary randomised and controlled single-blinded trial was conducted on 24 participants (ten males, 14 females between the ages of 18 to 50 years (median age of 40.5 Consent was obtained and participants were randomly allocated to one of three groups – ENAR, Transcutaneous Electrical Nerve Stimulation (TENS, or control therapy – to test the hypothesis that ENAR therapy would result in superior pain reduction/disability and improvements in neck function compared with TENS or control intervention. The treatment regimen included twelve 15-minute treatment sessions over a six week period, followed by two assessment periods. Visual Analogue Scale (VAS pain scores, Neck Disability Index (NDI scores, Patient Specific Functional Scale (PSFS scores and Short Form 36v1 (SF-36 quality of life scores reported by participants were collected at each of the assessments points throughout the trial (0, 6, 12, 18 and 24 weeks. Results Eligible participants (n = 30 were recruited and attended clinic visits for 6 months from the time of randomisation. Final trial sample (n = 24 comprised 9 within the ENAR group, 7 within the TENS group and 8 within the control group. With an overall study power of 0.92, the ENAR group showed a decrease in mean pain score from measurement at time zero (5.0 ± 0.79 95%CI to the first follow-up measurement at six weeks (1.4 ± 0.83 95%CI. Improvement was maintained until week 24 (1.75 ± 0.9 95%CI. The TENS and control groups showed consistent pain levels throughout the trial (3.4 ± 0.96 95%CI and 4.1 ± 0.9 95%CI respectively.

    Pre-operative weight loss has been consistently associated with increased post-operative morbidity. The study aims to determine if pre-operative oral nutritional supplements (ONSs) with dietary advice reduce post-operative complications. Single-blinded randomized controlled trial. People with colorectal cancer scheduled for surgery with pre-operative weight loss >1 kg/3-6 months were randomized by using stratified blocks (1:1 ratio) in six hospitals (1 November 2013-28 February 2015). Intervention group was given 250 mL/day ONS (10.1 KJ and 0.096 g protein per mL) and dietary advice. Control group received dietary advice alone. Oral nutritional supplements were administered from diagnosis to the day preceding surgery. Research team was masked to group allocation. Primary outcome was patients with one or more surgical site infection (SSI) or chest infection; secondary outcomes included percentage weight loss, total complications, and body composition measurements. Intention-to-treat analysis was performed with both unadjusted and adjusted analyses. A sample size of 88 was required. Of 101 participants, (55 ONS, 46 controls) 97 had surgery. In intention-to-treat analysis, there were 21/45 (47%) patients with an infection-either an SSI or chest infection in the control group vs. 17/55 (30%) in the ONS group. The odds ratio of a patient incurring either an SSI or chest infection was 0.532 (P = 0.135 confidence interval 0.232 to 1.218) in the unadjusted analysis and when adjusted for random differences at baseline (age, gender, percentage weight loss, and cancer staging) was 0.341 (P = 0.031, confidence interval 0.128 to 0.909). Pre-operative percentage weight loss at the first time point after randomization was 4.1% [interquartile range (IQR) 1.7-7.0] in ONS group vs. 6.7% (IQR 2.6-10.8) in controls (Mann-Whitney U P = 0.021) and post-operatively was 7.4% (IQR 4.3-10.0) in ONS group vs. 10.2% (IQR 5.1-18.5) in controls (P = 0.016).

    Full Text Available Metabolic syndrome (MS is characterized by a combination of cardiovascular (CV risk factors (hypertension, dyslipidemia, obesity, and alterations in glucose homeostasis. Insulin resistance is suggested to be the common pathogenic background. This syndrome is also a risk factor for diabetes and chronic kidney disease. In renal transplant recipients, MS has been shown to be an independent risk factor for chronic allograft dysfunction, graft failure, new-onset diabetes, and CV disease. We performed a cross-sectional study on 106 stable renal transplant recipients to detect MS between January 2013 and August 2013. This syndrome was diagnosed according to the National Cholesterol Education Program–Adult Treatment Panel III criteria. Patients with history of diabetes mellitus were excluded from the study. In this group of patients, 56 (52.8% had MS. There were 32 males (57.1% and 24 females (42.9%. The mean age of the MS group was significantly higher than the non-MS group. The mean serum creatinine was higher in the MS group than the non-MS group, but there was no significant difference between them (P >0.05. The calculated glomerular filtration rate was also similar in the two groups (P >0.05. The patients with MS had higher body weight (64.61 ± 14.17 kg vs. 58.76 ± 11.70 kg, P 25 kg/m2 in the MS group was 75% versus 25% in the non-MS group (P <0.05. Since MS is an important and common risk factor in renal transplant recipients, we have to try to prevent it by educating the patients to control it by modifying their lifestyle. Efforts toward promoting healthy diets, physical activity, and blood pressure control must be undertaken.

    Efficacy in previous studies of surgical treatments of refractory multiple sclerosis tremor using lesioning or deep brain stimulation (DBS) has been variable. The aim of this study was to investigate the safety and efficacy of dual-lead thalamic DBS (one targeting the ventralis intermedius-ventralis oralis posterior nucleus border [the VIM lead] and one targeting the ventralis oralis anterior-ventralis oralis posterior border [the VO lead]) for the treatment of multiple sclerosis tremor. We did a single centre, single-blind, prospective, randomised pilot trial at the University of Florida Center for Movement Disorders and Neurorestoration clinic (Gainesville, FL, USA). We recruited adult patients with a clinical diagnosis of multiple sclerosis tremor refractory to previous medical therapy. Before surgery to implant both leads, we randomly assigned patients (1:1) to receive 3 months of optimised single-lead DBS-either VIM or VO. We did the randomisation with a computer-generated sequence, using three blocks of four patients, and independent members of the Center did the assignment. Patients and all clinicians other than the DBS programming nurse were masked to the choice of lead. Patients underwent surgery 1 month after their baseline visit for implantation of the dual lead DBS system. A pulse generator and two extension cables were implanted in a second surgery 3-4 weeks later. Patients then received an initial 3-month period of continuous stimulation of either the VIM or VO lead followed by blinded safety assessment of their tremor with the Tolosa-Fahn-Marin Tremor Rating Scale (TRS) during optimised VIM or VO lead stimulation at the end of the 3 months. After this visit, both leads were activated in all patients for an additional 3 months, and optimally programmed during serial visits as dictated by a prespecified programming algorithm. At the 6-month follow-up visit, TRS score was measured, and mood and psychological batteries were administered under four

    Partial oculocutaneous albinism and immunodeficiency (OCA-ID) diseases are autosomal recessive syndromes characterized by partial hypopigmentation and recurrent infections. Moreover, some OCA-ID syndromes confer susceptibility to develop a life-threatening hyperinflammatory condition called hemophagocytic lymphohistiocytosis (HLH). We investigated the genetic, clinical and immunological characteristics of 20 OCA patients. Herein, we present the clinical and immunological characteristics of 20 OCA patients who referred to the Department of Pediatric Immunology, Erciyes University Medical Faculty in Kayseri, Turkey between 2004 and 2014. Of the 20 OCA patients, 7 fulfilled diagnostic criteria for HLH, 9 showed defective functions of CD8 T cells and natural killer cells, and 8 received a definitive molecular diagnosis. Among the patients, we also report a patient diagnosed with two different genetic defects, in TYR and JAK3 genes, causing, respectively, OCA and ID. Our results illustrate the variability of clinical presentations and disease severity in OCA-ID patients, with consequent challenges in diagnosing and treating these patients.

    Steroid-resistant nephrotic syndrome (SRNS) is the second most frequent cause of ESRD in the first two decades of life. Effective treatment is lacking. First insights into disease mechanisms came from identification of single-gene causes of SRNS. However, the frequency of single-gene causation and its age distribution in large cohorts are unknown. We performed exon sequencing of NPHS2 and WT1 for 1783 unrelated, international families with SRNS. We then examined all patients by microfluidic multiplex PCR and next-generation sequencing for all 27 genes known to cause SRNS if mutated. We detected a single-gene cause in 29.5% (526 of 1783) of families with SRNS that manifested before 25 years of age. The fraction of families in whom a single-gene cause was identified inversely correlated with age of onset. Within clinically relevant age groups, the fraction of families with detection of the single-gene cause was as follows: onset in the first 3 months of life (69.4%), between 4 and 12 months old (49.7%), between 1 and 6 years old (25.3%), between 7 and 12 years old (17.8%), and between 13 and 18 years old (10.8%). For PLCE1, specific mutations correlated with age of onset. Notably, 1% of individuals carried mutations in genes that function within the coenzyme Q10 biosynthesis pathway, suggesting that SRNS may be treatable in these individuals. Our study results should facilitate molecular genetic diagnostics of SRNS, etiologic classification for therapeutic studies, generation of genotype-phenotype correlations, and the identification of individuals in whom a targeted treatment for SRNS may be available.

    Fragile X syndrome is the leading cause of inherited mental impairment and is associated with expansions of CGG repeats within the FMR1 gene. To detect expanded CGG repeats, we developed a dual-mode single-molecule fluorescence assay that allows acquisition of two parallel, independent measures of repeat number based on (1) the number of Cy3-labeled probes bound to the repeat region and (2) the physical length of the electric field-linearized repeat region, obtained from the relative position of a single Cy5 dye near the end of the repeat region. Using target strands derived from cell-line DNA with defined numbers of CGG repeats, we show that this assay can rapidly and simultaneously measure the repeats of a collection of individual sample strands within a single field of view. With a low occurrence of false positives, the assay differentiated normal CGG repeat lengths (CGG( N ), N = 23) and expanded CGG repeat lengths (CGG( N ), N = 118), representing a premutation disease state. Further, mixtures of these DNAs gave results that correlated with their relative populations. This strategy may be useful for identifying heterozygosity or for screening collections of individuals, and it is readily adaptable for screening other repeat disorders.

    N-Methyl-3,4-methylenedioxyamphetamine (MDMA), also called "Ecstasy," is a commonly abused psychoactive drug among the American youth. We present the case of a 23-year-old Korean-American woman who presented with seizure, delirium, and rigidity after MDMA ingestion. She was febrile (38.7°C), tachycardic (188 beats/min), tachypneic (26 breaths/min) with a borderline blood pressure (95/43 mm Hg). Examination revealed generalized muscle rigidity, tremors, hyperreflexia, and ocular clonus, leading to the diagnosis of serotonin syndrome. Urine toxicology screen was only positive for amphetamines, consistent with the history of MDMA ingestion. Initial laboratory testing showed thrombocytopenia, further testing showed deranged prothrombin time, partial thromboplastin time, decreased fibrinogen, and elevated D-dimer, suggesting disseminated intravascular coagulation. Hepatic transaminases trended up dramatically reflecting acute hepatitis. The patient received supportive care and improved by hospital day 3. MDMA toxicity manifested as serotonin syndrome, hepatitis, and coagulopathy is exceedingly rare. MDMA is metabolized by the hepatic CYP2D6 enzyme. Certain populations, such as Koreans, Chinese, and Japanese have a high prevalence of a polymorphism that confers reduced enzyme activity. We discuss this hypothesis as a possible cause for this severe presentation in our patient after a single ingestion.

    [corrected] Nephrotic syndrome is one of the most frequent glomerular diseases among children, and steroid therapy remains as the treatment choice. In spite of this, 10 to 15% of the patients are steroidresistant, and the best therapy for such cases has never been defined. Mycophenolate acid (MA) is one of the treatments used in such situations. To describe the clinical behavior of children diagnosed with steroid-resistant nephrotic syndrome (SRNS) and to assess the therapeutic response to MA. This was a retrospective and descriptive study. 26 clinical records of patients with SRNS; 70% male and 30% female. All patients underwent kidney biopsies, which showed a predominance of focal segmental glomerulosclerosis (FSGS). The immunosuppresive drugs used were: Mycophenolate mofetil (MMF) 100%, Cyclosporine 69.2%, Cyclophosphamide 23.1%, and Rituximab 23%. One month after treatment initiation with MMF 61.5% achieved remission. The median of relapses per year for the patients was 3 (p25: 2.75 - p75: 4). This median became 1 (p25: 1 - p75: 3.25) after using this medication (p = 0.08). Furthermore, prior to the start of the MMF treatment, the median of the steroid dose was 1 (p25: 0.5- p75: 1.62) mg/k/day. After using MMF, this median became 0.07 (p25: 0 - p75: 0.55) mg/k/day (p < 0.001), in 8 patients prednisolone was stopped. In our experience, treatment with MMF showed positive results such as decrease in the frequency of relapses, less proteinuria, and reduction in the dose of steroids administered without deterioration of glomerular filtration rates. However, more studies are needed to assess efficacy, safety, and optimal dosage.

    Simulation-based training (SBT) has developed into an established method of medical training. Studies focusing on the education of medical students have used simulation as an evaluation tool for defined skills. A small number of studies provide evidence that SBT improves medical students' skills in the clinical setting. Moreover, they were strictly limited to a few areas, such as the diagnosis of heart murmurs or the correct application of cricoid pressure. Other studies could not prove adequate transferability from the skills gained in SBT to the patient site. Whether SBT has an effect on medical students' skills in anesthesiology in the clinical setting is controversial. To explore this issue, we designed a prospective, randomized, single-blind trial that was integrated into the undergraduate anesthesiology curriculum of our department during the second year of the clinical phase of medical school. This study intended to explore the effect of SBT on medical students within the mandatory undergraduate anesthesiology curriculum of our department in the operating room with respect to basic skills in anesthesiology. After obtaining ethical approval, the participating students of the third clinical semester were randomized into two groups: the SIM-OR group was trained by a 225 min long SBT in basic skills in anesthesiology before attending the operating room (OR) apprenticeship. The OR-SIM group was trained after the operating room apprenticeship by SBT. During SBT the students were trained in five clinical skills detailed below. Further, two clinical scenarios were simulated using a full-scale simulator. The students had to prepare the patient and perform induction of anesthesia, including bag-mask ventilation after induction in scenario 1 and rapid sequence induction in scenario 2. Using the five-point Likert scale, five defined skills were evaluated at defined time points during the study period. 1) application of the safety checklist, 2) application of

    This pilot study was devoted to the effect of static magnetic field (SMF)-exposure on erosive gastritis. The randomized, self- and placebo-controlled, double-blind, pilot study included 16 patients of the 2nd Department of Internal Medicine, Semmelweis University diagnosed with erosive gastritis. The instrumental analysis followed a qualitative (pre-intervention) assessment of the symptoms by the patient: lower heartburn (in the ventricle), upper heartburn (in the oesophagus), epigastric pain, regurgitation, bloating and dry cough. Medical diagnosis included a double-line upper panendoscopy followed by 30 min local inhomogeneous SMF-exposure intervention at the lower sternal region over the stomach with peak-to-peak magnetic induction of 3 mT and 30 mT m−1 gradient at the target site. A qualitative (post-intervention) assessment of the same symptoms closed the examination. Sham- or SMF-exposure was used in a double-blind manner. The authors succeeded in justifying the clinically and statistically significant beneficial effect of the SMF- over sham-exposure on the symptoms of erosive gastritis, the average effect of inhibition was 56% by p = 0.001, n = 42 + 96. This pilot study was aimed to encourage gastroenterologists to test local, inhomogeneous SMF-exposure on erosive gastritis patients, so this intervention may become an evidence-based alternative or complementary method in the clinical use especially in cases when conventional therapy options are contraindicated.

    The study investigated whether participants who received Reiki would show greater health and well-being benefits than a group who received no Reiki. A method of blinding participants to Reiki was also tested, where non-contact Reiki or No-Reiki with random assignment was given to 35 healthy psychology undergraduates whose attention was absorbed in one of three tasks involving self-hypnosis/relaxation. Participants experienced ten 20-min intervention sessions over a period of two and a half to 12 weeks. Reiki was directed by the experimenter who sat behind the participants as they were absorbed in the tasks. Self-report measures of illness symptoms, mood and sleep were assessed pre-post-intervention as was salivary cortisol. While the Reiki group had a tendency towards a reduction in illness symptoms, a substantive increase was seen in the No-Reiki. The Reiki group also had a near-significant comparative reduction in stress, although they also had significantly higher baseline illness symptoms and stress scores. The Reiki blinding was successful - the groups did not differ statistically in their beliefs regarding group membership. The results are suggestive that the Reiki buffered the substantive decline in health in the course of the academic year seen in the No-Reiki group.

    The relationship between Guillain-Barré syndrome (GBS) and malignancy is uncertain. We retrospectively analyzed data of 118 consecutive patients admitted with GBS from Birmingham, U.K. (2001-2012). We calculated relative cancer risk using different definitions and determined characteristics of malignancy-associated GBS. Malignancy was globally commoner in our GBS cohort compared to the general population (odds ratio: 2.08; CI: 1.06-3.71; p=0.036). However, this was unconfirmed if paraneoplastic criteria were applied. GBS patients with cancer were significantly more likely to be older (p=0.043), hyponatremic (p=0.037) and demonstrate more axonal loss (pmalignancy group (p=0.002) and neurological improvement less likely (p=0.023). In-patient mortality was significantly higher in patients with malignancy (pcancer risk is higher in GBS than in the general population, although definition-dependent. Malignancy requires consideration in elderly, hyponatremic subjects with normal CSF protein, severe axonal loss, who fail to improve post-treatment. Copyright © 2017 Elsevier B.V.

Retrospective study of interventions, outcomes and perinatal follow-up of GGG treated for TTS. Between 2002 and 2013, 25 GGG complicated by TTTS were seen in our center, 20 dichorionic and 5 monochorionic. The mean gestational age (GA) at diagnosis of TTTS was 19.7 GW (±2.4) with 2, 4, 16 and 1 pregnancies at Quintero's stage I, II, III and V, respectively. They had a fetoscopy at an average GA of 19 GW and 6 days. There were 3 (13.0%) late miscarriages. The average GA at delivery was of 29.6 GW overall (26.3 GW and 31.1 GW in monochorionic and dichorionic pregnancies respectively). The overall fetal survival rate was 57.97% (40% and 66.7% in the group of monochorionic dichorionic pregnancies, respectively). However, neonatal mortality (<28 days) is 17.5%. GGG operated by fetoscopy for TTTS have a survival rate of three, at least 2 and at least 1 fetus of 21.7%, 69.6% and 82.6% respectively. The overall fetal survival rate is 59.97%.

    Autism Spectrum Conditions (ASC) are a group of developmental conditions which affect communication, social interactions and behaviour. Mitochondrial oxidative dysfunction has been suggested as a mechanism of autism based on the results of multiple genetic association and expression studies. SLC25A12 is a gene encoding a calcium-binding carrier protein that localizes to the mitochondria and is involved in the exchange of aspartate for glutamate in the inner membrane of the mitochondria regulating the cytosolic redox state. rs2056202 SNP in this gene has previously been associated with ASC. SNPs rs6716901 and rs3765166 analysed in this study have not been previously explored in association with AS. We genotyped three SNPs (rs2056202, rs3765166, and rs6716901) in SLC25A12 in n?=?117 individuals with Asperger syndrome (AS) and n?=?426 controls, all of Caucasian ancestry. rs6716901 showed significant association with AS (P?=?0.008) after correcting for multiple testing. We did not replicate the previously identified association between rs2056202 and AS in our sample. Similarly, rs3765166 (P?=?0.11) showed no significant association with AS. The present study, in combination with previous studies, provides evidence for SLC25A12 as involved in the etiology of AS. Further cellular and molecular studies are required to elucidate the role of this gene in ASC.

    Full Text Available Background/Aim. Serrated polyposis syndrome (SPS is a rare condition characterized by multiple serrated polyps throughout the colon and rectum. The aim of this study was to evaluate the clinicopathological characteristics of SPS in Koreans. Methods. This retrospective analysis of prospectively collected data was performed using information from the endoscopy, clinical records, and pathology database system of Uijeongbu St. Mary’s Hospital. Consecutive patients satisfying the updated 2010 World Health Organization criteria for SPS between June 2011 and May 2014 were enrolled. Results. Of the 17,552 patients who underwent colonoscopies during the study period, 11 (0.06% met the criteria for SPS. The mean age of these patients was 55.6 years. Ten patients (91% were males. None had a family history of CRC or a first-degree relative with SPS. Seven patients (64% had synchronous advanced adenoma. One patient had coexistence of SPS with CRC that was diagnosed at the initial colonoscopy. Five patients (45% had more than 30 serrated polyps. One of the patients underwent surgery and 10 underwent endoscopic resection. Conclusion. The prevalence of SPS in this study cohort was comparable to that in Western populations. Considering the high risk of CRC, correct diagnosis and careful follow-up for SPS are necessary.

Of children followed ≥1 year (, mean follow-up years, 19 had severe and 18 mild-to-moderate kidney injury, a total sequelae rate, of 18.6%. Ten years or more after-HUS (, mean follow-up years, 8 (9.4% patients demonstrated serious complications and 22 (25.9% mild-to-moderate, including 14 (16% microalbuminuria: total sequelae, 35.3%. Conclusions. Patients with D+ HUS should be monitored at least 5 years, including microalbuminuria testing, especially if dialysis was required. The cause of the declining incidence of D+HUS is elusive. However, conceivably, improved public health education may have played an important role in the prevention of food-borne disease.

    Full Text Available Controlled hypoventilation while accepting hypercapnia has been advocated to reduce ventilator-induced lung injury. The aim of the study was to analyze outcomes of a cohort of immunocompromised children with acute respiratory distress syndrome (ARDS ventilated with a strategy of stepwise increasing PCO2 targets up to 140 mm Hg.Retrospective analysis of outcomes of a cohort of children with oncologic disease or after stem cell transplantation and severe respiratory failure in comparison with a historical control cohort.Out of 150 episodes of admission to the PICU 88 children underwent invasive mechanical ventilation for >24h (overall survival 75%. In a subgroup of 38 children with high ventilator requirements the PCO2 target ranges were increased stepwise. Fifteen children survived and were discharged from the PICU. Severe pulmonary hypertension was seen in two patients and no case of cerebral edema was observed. Long term outcome was available in 15 patients and 10 of these patients survived without adverse neurological sequelae. With introduction of this strategy survival of immunocompromised children undergoing mechanical ventilation for >24h increased to 48% compared to 32% prior to introduction (historical cohort.A ventilation strategy incorporating very high carbon dioxide levels to allow for low tidal volumes and limited inspiratory pressures is feasible in children. Even severe hypercapnia may be well tolerated. No severe side effects associated with hypercapnia were observed. This strategy could potentially increase survival in immunocompromised children with severe ARDS.

    To determine the prevalence of metabolic syndrome (MS) in renal transplant recipients (RTR) using the modified Asian National Cholesterol Education Programme-Adult Treatment Panel III (NCEP-ATP III) criteria. A cross-sectional study was conducted on 200 RTRs between January 2008-August 2008. All were more than six months post transplant and above 18 years of age. Subjects with pre-transplant diabetes or New Onset Diabetes Mellitus after renal transplantation, with overt infections, dyslipidaemia or on lipid lowering medication and taking immunosuppressive drugs of the target organ inhibitor group as rapamycin, were excluded. The prevalence of MS was determined using the (NCEP-ATP III) criteria modified for Asians which includes waist circumference, triglycerides, HDL cholesterol, blood pressure and fasting blood glucose. Of the 200 recipients studied, 87 (43.5%) had MS. There were 58 (39.4%) males and 29 (54.7%) females which shows female predominance. The mean age of the MS group was more then that of the non MS group (p creatinine was higher in MS group but there was no significant difference. The prevalence of MS was 4.5% in the first twelve months, with a rise in this figure to 41.3% between one to five years after transplantation. There is a high prevalence of MS in Renal Transplant Recipients specifically after one year of transplantation.

    Antiphospholipid Syndrome (APS) is an autoimmune disorder with clinical and laboratory features of vascular thrombosis, pregnancy loss, and persistent antiphospholipid antibodies (aPLs). The pathophysiology is thought to involve the activation of endothelial cells, monocytes, platelets, and complement by aPLs. Disease can range from asymptomatic to rapidly fatal catastrophic APS. We present a case of a 34-year-old male referred for pancytopenia and splenomegaly. On examination, he had decreased sensation and 4/5 power in the left upper extremity. A lacy, purplish rash was noted on the trunk and upper extremity. MRI of brain showed acute/subacute lacunar infarctions. Laboratory studies revealed an elevated lactate dehydrogenase level, bilirubin and ferritin, decreased haptoglobin, and positive Coombs test. Antinuclear antibody test was negative and antiphospholipid antibody panel revealed positivity for anti-cardiolipin IgG and IgM, antiphosphatidylserine IgG, and anti-β2-glycoprotein IgG. The patient was diagnosed with primary APS. Pancytopenia is relatively rare in primary APS and is more often seen in secondary APS. Our patient demonstrated involvement of multiple organ systems as well as livedo reticularis and autoimmune-related findings such as Raynaud phenomenon and Coombs positive hemolytic anemia. We discuss the various clinical and laboratory findings in patients with APS that aid in diagnosis, as well as important management considerations. PMID:28620416

    Full Text Available Purpose: In outbreaks of infectious disease, medical students are easily overlooked in the management of healthcare personnel protection although they serve in clinical clerkships in hospitals. In the early summer of 2015, Middle East respiratory syndrome (MERS struck South Korea, and students of Sungkyunkwan University School of Medicine (SKKUSOM were at risk of contracting the disease. The purpose of this report is to share SKKUSOM’s experience against the MERS outbreak and provide suggestions for medical schools to consider in the face of similar challenges. Methods: Through a process of reflection-on-action, we examined SKKUSOM’s efforts to avoid student infection during the MERS outbreak and derived a few practical guidelines that medical schools can adopt to ensure student safety in outbreaks of infectious disease. Results: The school leadership conducted ongoing risk assessment and developed contingency plans to balance student safety and continuity in medical education. They rearranged the clerkships to another hospital and offered distant lectures and tutorials. Five suggestions are extracted for medical schools to consider in infection outbreaks: instant cessation of clinical clerkships; rational decision making on a school closure; use of information technology; constant communication with hospitals; and open communication with faculty, staff, and students. Conclusion: Medical schools need to take the initiative and actively seek countermeasures against student infection. It is essential that medical schools keep constant communication with their index hospitals and the involved personnel. In order to assure student learning, medical schools may consider offering distant education with online technology.

    BackgroundMedian arcuate ligament syndrome (MALS) is a rare entity that occurs when the median arcuate ligament of the diaphragm is low-lying, causing a compression to the underlying celiac trunk. We reviewed the vascular changes associated with MALS in an effort to emphasize the seriousness of this disease and the complications that may result.MethodsThis is a retrospective descriptive analysis of 23 consecutive patients diagnosed with MALS between January 1, 2012 and December 31, 2015 at a tertiary medical center. Computed tomographic (CT) scans, medical records, and patient follow-up were reviewed.ResultsThe number of patients included herein was 23. The median age was 56 years (17–83). Sixteen patients (69.6%) had a significant arterial collateral circulation. Eleven patients (47.8%) were found to have visceral artery aneurysms; 4 patients (36.4%) bled secondary to aneurysm rupture. All ruptured aneurysms were treated with endovascular approach. The severity of the hemodynamic changes appears to be greater with complete occlusion,ConclusionsMALS causes pathological hemodynamic changes within the abdominal vasculature. Follow-up is advised for patients who develop a collateral circulation. Resulting aneurysms should preferably be treated when the size ratio approaches three. Treatment of these aneurysms can be done via an endovascular approach coupled with possible celiac artery decompression to restore physiologic blood flow.

    Full Text Available There is a paucity of information on outpatient management and risk factors for hospitalization and complications in childhood nephrotic syndrome (NS. We described the management, patient adherence, and inpatient and outpatient usage of 87 pediatric NS patients diagnosed between 2006 and 2012 in the Atlanta Metropolitan Statistical Area. Multivariable analyses were performed to examine the associations between patient characteristics and disease outcome. We found that 51% of the patients were treated with two or more immunosuppressants. Approximately half of the patients were noted to be nonadherent to medications and urine protein monitoring. The majority (71% of patients were hospitalized at least once, with a median rate of 0.5 hospitalizations per patient year. Mean hospital length of stay was 4.0 (3.8 days. Fourteen percent of patients experienced at least one serious disease complication. Black race, frequently relapsing/steroid-dependent and steroid-resistant disease, and the first year following diagnosis were associated with higher hospitalization rates. The presence of comorbidities was associated with longer hospital length of stay and increased risk of serious disease complications. Our results highlight the high morbidity and burden of NS and point to particular patient subgroups that may be at increased risk for poor outcome.

    Little is known about the relative efficacy of high-protein vs. conventional diet plans that include partial meal replacements on body fat loss in obese subjects with metabolic syndrome. We aimed to evaluate the efficacy of two low-calorie diets with partial meal replacement plans-a high-protein plan (HP) and a nutritionally balanced conventional (C) plan-on reducing obesity in obese subjects with metabolic syndrome. In a 12-week, double-blind study, we randomised 75 participants to either the HP- or the C-plan group. We recorded key metrics at 0 and 12 weeks. The overall mean weight loss was 5 kg in the HP-plan group and 4.9 kg in the C-plan group (p = 0.72). Truncal fat mass decreased 1.6 kg in the HP-plan group (p or = 70% dietary compliance, however, truncal and whole body fat mass decreased more in the HP-plan group (Delta 2.2 kg and Delta 3.5 kg respectively) than in the C-plan group (Delta 1.3 kg and Delta 2.3 [corrected] kg respectively) (p < 0.05). The HP- and C-plans had a similar effect on weight and abdominal fat reduction, but the HP-plan was more effective in reducing body fat among compliant subjects.

    To describe temporal and spatial gait characteristics in individuals with Cri du Chat syndrome (CdCS) and to explore the effects of performing concurrent manual tasks while walking. The gait parameters of 14 participants with CdCS (mean age 10.3, range 3-20 years) and 14 age-matched controls (mean age 10.1, range 3-20 years) were collected using the GAITRite ® instrumented walkway. All participants first walked without any concurrent tasks and then performed 2 motor dual task walking conditions (pitcher and tray). Individuals with CdCS took more frequent, smaller steps than controls, but, on average, had a comparable gait speed. In addition, there was a significant task by group interaction. Participants decreased gait speed, decreased cadence, decreased step length, and increased% time in double limb support under dual task conditions compared to single task conditions. However, the age-matched controls altered their gait for both manual tasks, and the participants with CdCS only altered their gait for the tray task. Although individuals with CdCS ambulate with a comparable gait speed to age-matched controls under single task conditions, they did not significantly alter their gait when carrying a pitcher with a cup of water inside, like controls. It is not clear whether or not individuals with CdCS had difficulty attending to task demands or had difficulty modifying their gait. Copyright © 2016 Elsevier B.V. All rights reserved.

    Atypical hemolytic uremic syndrome (aHUS) is a rare genetic life-threatening disease of chronic uncontrolled complement activation leading to thrombotic microangiopathy (TMA) and severe end-organ damage. Eculizumab, a terminal complement inhibitor approved for aHUS treatment, was reported to improve hematologic and renal parameters in 2 prior prospective phase 2 studies. This is the largest prospective study of eculizumab in aHUS to date, conducted in an adult population. Open-label single-arm phase 2 trial. Patients 18 years or older with aHUS (platelet count dialysis, 5 recovered kidney function before eculizumab initiation and 15 of the remaining 19 (79%) discontinued dialysis during eculizumab treatment. No patients lost existing transplants. Quality-of-life measures were significantly improved. Two patients developed meningococcal infections; both recovered, and 1 remained on eculizumab treatment. Single-arm open-label design. Results highlight the benefits of eculizumab in adult patients with aHUS: improvement in hematologic, renal, and quality-of-life parameters; dialysis discontinuation; and transplant protection.

    The objective of this study was to determine the effects of Mycoplasma hyopneumoniae and/or porcine reproductive and respiratory syndrome virus (PRRSV) vaccination on dually infected pigs. In total, 72 pigs were randomly divided into nine groups (eight pigs per group), as follows: five vaccinated and challenged groups, three non-vaccinated and challenged groups, and a negative control group. Single-dose vaccination against M. hyopneumoniae alone decreased the levels of PRRSV viremia and PRRSV-induced pulmonary lesions, whereas single-dose vaccination against PRRSV alone did not decrease nasal shedding of M. hyopneumoniae and mycoplasma-induced pulmonary lesions in the dually infected pigs. The M. hyopneumoniae challenge impaired the protective cell-mediated immunity induced by the PRRSV vaccine, whereas the PRRSV challenge did not impair the protective cell-mediated immunity induced by the M. hyopneumoniae vaccine. The present study provides swine practitioners and producers with efficient vaccination regimes; vaccination against M. hyopneumoniae is the first step in protecting pigs against co-infection with M. hyopneumoniae and PRRSV.

    Background and purpose: To compare the efficacy of two different dose-fractionation schedules for radiotherapy of patients with benign painful shoulder syndrome. Patients and methods: Between February 2006 and February 2010, 312 consecutive evaluable patients were recruited for this prospective randomized trial. All patients received radiotherapy with an orthovoltage technique. One radiotherapy course consisted of 6 single fractions in 3 weeks. In case of insufficient remission of pain after 6 weeks, a second radiation series was performed. Patients were randomly assigned to receive either single doses of 0.5 or 1.0 Gy. The endpoint was pain reduction. Pain was measured before, right after, and 6 weeks after radiotherapy using a visual analogue scale (VAS) and a comprehensive pain score (CPS). Results: The overall response rate for all patients was 83% directly after and 85% 6 weeks after radiotherapy. The mean VAS values before, directly after, and 6 weeks after treatment for the 0.5 and 1.0 Gy groups were 56.8 {+-} 23.7 and 53.2 {+-} 21.8 (p = 0.158), 38.2 {+-} 26.1 and 34.0 {+-} 24.5 (p = 0.189), and 33.0 {+-} 27.2 and 23.7 {+-} 22.7 (p = 0.044), respectively. The mean CPS before, directly after, and 6 weeks after treatment was 9.7 {+-} 3.0 and 9.5 {+-} 2.7 (p = 0.309), 6.1 {+-} 3.6 and 5.4 {+-} 3.6 (p = 0.096), 5.3 {+-} 3.7 and 4.1 {+-} 3.7 (p = 0.052), respectively. Despite a slight advantage in the VAS analysis for the 1.0 Gy group for delayed response, the CPS analysis revealed no statistically significant differences between the two single-dose trial arms for early (p = 0.652) and delayed response quality (p = 0.380). Conclusion: Radiotherapy is an effective treatment option for the management of benign painful shoulder syndrome. Concerning radiation protection, the dose for a radiotherapy series is recommended not to exceed 3-6 Gy. (orig.)

    Aims. To assess trends in the incidence of pediatric diarrhea-associated hemolytic uremic syndrome (D+ HUS) and document long-term renal sequelae. Methods. We conducted a retrospective cohort study of children with D+ HUS admitted to a tertiary care pediatric hospital in Montreal, Canada, from 1976 to 2010. In 2010, we recontacted patients admitted before 2000. Results. Of 337 cases, median age at presentation was 3.01 years (range 0.4–14). Yearly incidence peaked in 1988 and 1994-95, returning to near-1977 levels since 2003. Twelve patients (3.6%) died and 19 (5.6%) experienced long-term renal failure. Almost half (47%) The patients required dialysis. Need for dialysis was the best predictor of renal sequelae, accounting for 100% of severe complications. Of children followed ≥1 year (n = 199, mean follow-up 8.20 ± 6.78 years), 19 had severe and 18 mild-to-moderate kidney injury, a total sequelae rate, of 18.6%. Ten years or more after-HUS (n = 85, mean follow-up 15.4 ± 5.32 years), 8 (9.4%) patients demonstrated serious complications and 22 (25.9%) mild-to-moderate, including 14 (16%) microalbuminuria: total sequelae, 35.3%. Conclusions. Patients with D+ HUS should be monitored at least 5 years, including microalbuminuria testing, especially if dialysis was required. The cause of the declining incidence of D+HUS is elusive. However, conceivably, improved public health education may have played an important role in the prevention of food-borne disease.

  17. Oxidant production and SOD1 protein expression in single skeletal myofibers from Down syndrome mice

    Full Text Available Down syndrome (DS is a genetic condition caused by the triplication of chromosome 21. Persons with DS exhibit pronounced muscle weakness, which also occurs in the Ts65Dn mouse model of DS. Oxidative stress is thought to be an underlying factor in the development of DS-related pathologies including muscle dysfunction. High-levels of oxidative stress have been attributed to triplication and elevated expression of superoxide dismutase 1 (SOD1; a gene located on chromosome 21. The elevated expression of SOD1 is postulated to increase production of hydrogen peroxide and cause oxidative injury and cell death. However, it is unknown whether SOD1 protein expression is associated with greater oxidant production in skeletal muscle from Ts65Dn mice. Thus, our objective was to assess levels of SOD1 expression and oxidant production in skeletal myofibers from the flexor digitorum brevis obtained from Ts65Dn and control mice. Measurements of oxidant production were obtained from myofibers loaded with 2′,7′-dichlorodihydrofluorescein diacetate (DCFH2-DA in the basal state and following 15 min of stimulated unloaded contraction. Ts65Dn myofibers exhibited a significant decrease in basal DCF emissions (p 0.05. Myofibers from Ts65Dn mice tended to be smaller and myonuclear domain was lower (p < 0.05. In summary, myofibers from Ts65Dn mice exhibited decreased basal DCF emissions that were coupled with elevated protein expression of SOD1. Stimulated contraction in isolated myofibers did not affect DCF emissions in either group. These findings suggest the skeletal muscle dysfunction in the adult Ts65Dn mouse is not associated with skeletal muscle oxidative stress.

    One of the underestimated causes of chronic pelvic pain (CPP) in women may be pelvic congestion syndrome (PCS) that is defined as the presence of varicose of ovarian and pelvic veins associated with chronic pain in the region of the pelvis. This pain is present longer than 6 months and intensifies with prolonged standing, coitus and menstruation. The disease constitutes a diagnostic as well as therapeutic problem, thus posing a challenge for the clinician. Transcatheter ovarian vein embolization might be a safe and effective option for PCS treatment. The objective of this study was to evaluate the efficacy of ovarian vein embolization ovarian as a method of the PCS treatment. Between 2002-2012, 11 embolization procedures were performed in 10 women (age range: 34-43; median age 39) with the diagnosis of PCS. One patient underwent embolization procedure twice. In 1 case the combined therapy of endovascular embolization and surgical phlebectomy of vulvar varices was performed. There were no major intrainterventional complications. In all the patients (100%) a significant improvement in the clinical status was noted. The procedure improved the quality of life in the patients. Three women (30%) had a mild recurrence of the symptoms at mid-term follow-up. Among 8 women who had complained of dyspareunia prior to embolization 6 patients reported complete pain relief, in other 2 cases the pain subsided partially. There was a significant decrease in the severity of symptoms associated with hemorrhoids. We consider embolization of insufficient ovarian veins an effective and safe way of treatment in a well-selected group of patients with PCS.

    Traditional Chinese medical treatment of primary Sjögren's syndrome has advantages over Western medicine in terms of fewer side effects and improved patient conditions. This study was a multicenter, randomized, double-blind, placebo-controlled clinical trial of the efficacy and safety of ShengJinRunZaoYangXue granules for the treatment of primary Sjögren's syndrome, including the symptoms of dry mouth and dry eye. We undertook a 6-week, double-blind, randomized trial involving 240 patients with primary Sjögren's syndrome at five centers in East China. A computer-generated randomization schedule assigned patients at a 2:1 ratio to receive either ShengJinRunZaoYangXue granules or placebo once daily. Patients and investigators were blinded to treatment allocation. The primary endpoints were the salivary flow rate, Schirmer test results, and sugar test results. Intention-to-treat and per-protocol analyses were performed. All 240 patients were randomly allocated to either the treatment group (n = 160, ShengJinRunZaoYangXue granules) or placebo group (n = 80) and were included in the intention-to-treat analysis. After program violation and loss to follow-up, a total of 199 patients were included in the per-protocol analysis. At six week, intention-to-treat and per-protocol analyses of the left-eye Schirmer I test results showed an improved difference of 1.36 mm/5 min (95% CI: 0.03 to 2.69 mm/5 min) and 1.35 mm/5 min (95% CI: 0.04 to 2.73 mm/5 min), respectively, and those of the right-eye Schirmer I test results showed an improved difference of 1.12 mm/5 min (95% CI: 0.02 to 2.22 mm/5 min) and 1.12 mm/5 min (95% CI: -0.02 to 2.27 mm/5 min), respectively. There was no significant difference between the two groups before treatment. After treatment, the between-group and within-group before-and-after paired comparison results were statistically significant (P dry eye and dry mouth after six weeks of treatment. The incidence of adverse events was 15.6% in the treatment

    Blind motion deblurring from a single image is a highly under-constrained problem with many degenerate solutions. A good approximation of the intrinsic image can therefore only be obtained with the help of prior information in the form of (often non-convex) regularization terms for both the intrinsic image and the kernel. While the best choice of image priors is still a topic of ongoing investigation, this research is made more complicated by the fact that historically each new prior requires the development of a custom optimization method. In this paper, we develop a stochastic optimization method for blind deconvolution. Since this stochastic solver does not require the explicit computation of the gradient of the objective function and uses only efficient local evaluation of the objective, new priors can be implemented and tested very quickly. We demonstrate that this framework, in combination with different image priors produces results with PSNR values that match or exceed the results obtained by much more complex state-of-the-art blind motion deblurring algorithms.

    Beckwith-Wiedemann Syndrome (BWS) is characterized by numerous growth abnormalities including exomphalos, macroglossia, gigantism, and hemihypertrophy or hemihyperplasia. The {open_quotes}BWS gene{close_quotes} appears to be maternally repressed and is suspected to function as a growth factor or regulator of somatic growth, since activation of this gene through a variety of mechanisms appears to result in somatic overgrowth and tumor development. Mosaic paternal isodisomy of 11p has been observed previously by others in patients with BWS by Southern blot analysis of genomic DNA. The interpretation of these results was primarily based on the intensities of the hybridization signals for the different alleles. In our study, we demonstrate somatic mosaicism directly through PCR and single cell analysis. Peripheral blood was obtained from a patient with BWS and initial genomic DNA analysis by PCR was suggestive of somatic mosaicism for paternal isodisomy of 11p. Through micromanipulation, single cells were isolated and subjected to primer extention preamplification. Locus-specific microsatellite marker analyses by PCR were performed to determine the chromosome 11 origins in the preamplified individual cells. Two populations of cells were detected, a population of cells with normal biparental inheritance and a population of cells with paternal isodisomy of 11p and biparental disomy of 11q. Using the powerful approach of single cell analysis, the detected somatic mosaicism provides evidence for a mitotic recombinational event that has resulted in loss of the maternal 11p region and gain of a second copy of paternal 11p in some cells. The direct demonstration of mosaicism may explain the variable phenotypes and hemihypertrophy often observed in BWS.

    The aim of this study was to investigate the agreement between body composition measurements made with two methods-single-frequency bioelectrical impedance analysis (SF-BIA) and bioelectrical impedance spectroscopy (BIS). The body composition measurements using SF-BIA and BIS were performed seven times during 6 months on 41 patients (13 men and 28 women) with metabolic syndrome who were taking part in a dietary intervention study. The mean [standard deviation (SD)] fat mass (FM) and median [interquartile range (IQR)] FM% measured with SF-BIA were 32.7 (6.7) kg and 36.3 (30.3-39.3)%, respectively, compared with 38.2 (8.7) kg and 40.9 (35.5-45.6)%, respectively, using BIS. The median (IQR) fat-free mass (FFM) was 60.0 (53.3-73.5) kg according to SF-BIA and 55.4 (48.8-66.5) kg according to BIS. These results obtained with the two methods were significantly different (P<0.001). Still highly significant correlations were found between the results obtained with SF-BIA and BIS for FM and FFM (all r≥0.89, P<0.001). Using Bland-Altman analysis, the bias was found to be -5.4 (4.1) kg for FM, -5.5 (3.7)% for FM%, and 5.4 (4.1) kg for FFM. Rather wide limits of agreement were found for FM, FM%, and FFM. Body composition data obtained using SF-BIA and BIS in subjects with metabolic syndrome were highly correlated but not interchangeable. FM was systematically lower when using SF-BIA than when using BIS.

    Although twice-daily application of propylene glycol-containing 2% minoxidil topical solution (MTS) stimulates new hair growth, higher concentrations of minoxidil in a once-daily, propylene glycol-free formulation may improve efficacy and reduce unpleasant side effects. We sought to compare the efficacy, safety, and acceptability and to show noninferiority of once-daily 5% minoxidil topical foam (MTF) with twice-daily 2% MTS in women with androgenetic alopecia. A total of 113 women with androgenetic alopecia were randomized to 24 weeks of treatment with 5% MTF or 2% MTS. The primary efficacy parameter was change from baseline in nonvellus target area hair count at week 24. Secondary end points included change in nonvellus target area hair width, overall efficacy by global photographic review as assessed by treatment-blinded evaluators and the subject herself, adverse events, and participants' assessment of product aesthetics. After 24 weeks, women randomized to 5% MTF once daily showed noninferior target area hair count and target area hair width and experienced greater, but nonsignificant, improvements in target area hair count, target area hair width, and overall efficacy by global photographic review than those randomized to 2% MTS used twice daily. 5% MTF was significantly superior to 2% MTS in participants' agreement with "the treatment does not interfere with styling my hair" (P = .002). Women randomized to 5% MTF experienced significantly lower rates of local intolerance (P = .046) especially in pruritus and dandruff compared with 2% MTS. Because of differences in the formulations tested, study participants were not blinded to treatment. Once-daily 5% MTF is noninferior and as effective for stimulating hair growth as twice-daily 2% MTS in women with androgenetic alopecia and is associated with several aesthetic and practical advantages.

    The study aim was to analyze the authors' experience with aortic root surgery in Marfan syndrome (MFS), and to expand the surgical outcome data of patients meeting the Ghent criteria (Marfan registry). Analyses were performed of data acquired from MFS patients (who met the Ghent criteria), including an aortic root surgery and Kaplan-Meier survival. Between April 2004 and February 2012, a total of 59 MFS patients (mean age at surgery 36 ± 13 years) underwent 67 operations for aortic root aneurysm (n = 52), aortic valve (AV) regurgitation (n = 15), acute aortic dissection (n = 2), and/or mitral valve (MV) regurgitation resulting from MV prolapse (n = 7). Of 59 initial operations, 21 (36%) involved AV-replacing root surgery, 38 (64%) AV-sparing root surgery, seven (12%) aortic arch or hemi-arch repair, and five (8%) simultaneous MV surgery. There were no early mortalities. The mean follow up was 6.8 ± 1.2 years, with five deaths (8%) and a relatively low reoperation rate (10 reoperations in nine patients; 14%). Seven reoperations involved AV or aortic root surgery (including four for AV regurgitation following failed AV-sparing surgery), two MV repair/replacements, and one coronary artery bypass graft. Eight patients (21%) with AV-sparing surgery had moderate/severe AV regurgitation at the last follow up before
