There are about 10004 clinical studies being (or have been) conducted in Brazil. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Halitosis, also known as bad breath, is a term used to define an unpleasant and foul odor that emanates from the mouth and may have local or systemic origin. This project aims to observe the presence of halitosis and to verify if the treatment with antimicrobial photodynamic therapy (aPDT) is effective against it. The investigators will select 45 students or UNINOVE employees, from 18 to 25 years old, with a diagnosis of halitosis, presenting sulfite (SH2) ≥ 112 ppb on gas chromatography. Patients will be randomly divided into 3 groups of 15, which will receive different treatments: Group 1: treatment with tongue scraper; Group 2: aPDT applied in the back region and middle third of the tongue; Group 3: combined treatment of tongue scraper and aPDT. For the aPDT we will use urucum manipulated in the concentration of 20% (Fórmula e Ação®) in spray, to be applied in sufficient quantity to cover the middle third and back of the tongue (5 sprinkles) for 5 minutes for incubation, associated with a LED (Valo Cordless Ultradent®). 6 points will be irradiated on the back of the tongue with a distance of 1 cm between the points, considering the halo of light scattering and effectiveness of aPDT. The apparatus shall be precalibrated at wavelength 440-480nm for 60 seconds per point, irradiance of 450mW/cm and the light shall be irradiated so that a halo of 2cm diameter is formed per point. The results of the halimetry will be compared before and immediately after the treatment, besides the microbiological analysis of the tongue coating, before and after the treatment. The normality of the data will be measured using the Shapiro-Wilk test, and in the case of normality the Variance Analysis (ANOVA) test will be applied, and in the case of non-parametric data, the Kruskal-Wallis test will be used. To analyze the results of each treatment in both periods of the study, the Wilcoxon test will be used.
Cerebellar ataxias are a group of disorders caused by cerebellar affections, for which currently no specific treatment is available. Some limited studies verified the effects of cerebellar transcranial magnetic stimulation (TMS) on ataxic symptoms, with good results. The hypothesis is that cerebellar TMS could improve ataxic symptoms in some patients and in these patients, chronic cerebellar stimulation through deep brain stimulation could be a therapeutic option. The rationale is to stimulate the dentate nucleus of the cerebellum in order to balance the functional asymmetry observed between both motor cortices after chronic cerebellar lesions.
This study evaluate the Duodenal Ileal Interposition with Sleeve Gastrectomy for Type 2 Diabetes Mellitus in grade 1 obesity and overweight patients.
The aim of this research will be to investigate in stroke patients whether upper limb motor function can be maximized in response to sensory stimulation by comparing protocols for the application of Transcranial Magnetic Stimulation (rTMS) in the cortical region of S1 and Sensory Therapy in the upper limb paretic. Patients will be randomly and randomly allocated into four groups, Group 1 (G1) composed of individuals who will receive the protocol for the application of rTMS in the ipsilateral S1 cortex and fictitious sensory therapy in the paretic upper limb; Group 2 (G2) subjects will receive protocol of Sensory Therapy in the upper limb ethical and application of fictitious rTMS in the ipsilesional S1 cortex; Group 3 (G3): application of the protocol of application of rTMS in the ipsilateral S1 cortex associated with Sensory Therapy in the upper limb paretic and, G4 (GSHAM) control group in which fictitious rTMS will be performed and fictitious Sensory Therapy in the paretic upper limb).
The study was prospective, randomized. Patients with cancer pain were evaluated, one group receiving methadone with morphine and another group receiving morphine as the only opioid. Pain intensity, total morphine dose and adverse effects were evaluated.
Introduction: The osteoarthrosis is incurable, one of the most incapacitating disease around the world and your prevalence is increasing every year. The main consequences of this disease is pain and loss of functionality as a result of biomechanical limitations coming from articular inflammation. Among the variability of therapeutic resources, we propose MatPilates like a no drug intervention, that probably will contribute for a decrease in the symptoms of this disease. Objective: It is hypothesized that MatPilates is a method capable of decrease pain and increase functionality in elderly woman with osteoarthrosis. Methods: This study is a randomized double blind clinical trial, in which the volunteer need be in between 60 and 69 years old. Will be formed of two groups: MatPilates Group (MG) and Control Group (CG), and the ideal "n" will be calculated in a pilot study.
The aim of this study was to compare the efficacy of PBM (660nm) and corticosteroid therapy with clobetasol propionate 0.05% in the treatment of OLP. This is a protocol for a randomized, controlled, double blind clinical trial. Fourty-four patients will be randomized in two experimental groups. Control group will be treated with clobetasol propionate 0.05% for 30 consecutive days and with placebo PBM twice a week. The experimental group will be treated with placebo gel for 30 consecutive days to mask the treatment and patients will receive PBM twice a week during 1 month (laser λ = 660±10 nm; power 100mW; radiant energy 177J/cm2; 5-s exposure time per point and 0.5J of energy per point. The primary variable (pain) and the secondary variables including clinical scores and functional scores as well as patient anxiety and depression (The Hospital Anxiety and Depression Scale-HADS), will be evaluated at the baseline, once a week during treatment and after 30 and 60 days of follow up. Evaluation of clinical resolution will be performed at the end of the treatment (30 days). Evaluation of recurrence will be performed after 30 and 60 days of follow up. Serum and salivary levels of IL-6, IL-10, IL-1β, INF-γ and TNF-α will be evaluated at baseline and at the end of treatment (30 days). Quality of life will be evaluated by OHIP-14 questionnaire at baseline, at the end of treatment and after 30 and 60 days of follow up. The chi-square test, Student's t-test and ANOVA will be used and the level of significance of 5% will be considered (p < 0.05).
The thoracolumbar segment fractures are the most frequent along the spine, and surgical treatment is indicated in unstable fractures. Surgical treatment has been performed through the posterior fixation pedicle fixation systems, and where necessary complemented by decompression of the spinal arthrodesis and previous channel. Surgical treatment has been performed by conventional open approach through the posterior incision on the midline, and detachment and removal of paraspinal muscles to access the posterior vertebral elements. The percutaneous minimally invasive surgery was introduced in the context of spinal surgery to reduce the morbidity associated with conventional open approach. It has been reported the lowest bleeding intra- and postoperative period, less pain, shorter hospital stay, rehabilitation and return to work faster with less use of minimally invasive percutaneous approach of the spine. However, predominates in the literature of clinical case reports and few prospective and randomized clinical trials. The performance of prospective randomized clinical trials have been required for the evaluation of the benefits of minimally invasive surgery in the treatment of the thoracolumbar spine fractures. The objective of the study is to compare the surgical treatment of fractures of the thoracolumbar spine using the conventional open approach or minimally invasive percutaneous approach to the stabilization of the vertebral segment affected, and using similar type of pedicle spinal fixation system. Patients will be evaluated in the preoperative, postoperative, 1,2,3,6,12 and 24 months by parameters related to the perioperative (intraoperative bleeding, surgery time), clinical (VAS, SF-36, HADS, EQ-5D-5L), images (radiographs and computed tomography). The study results will impact the guidelines of the surgical treatment of thoracolumbar spine fractures and may indicate the advantages or disadvantages of using surgery through conventional open approach to minimally invasive percutaneous surgery.

Two thirds will be the intervention group that will perform combined training, while the other third will be the control group that will have physiotherapy sessions.
OBJECTIVE: To evaluate the efficacy of vibro-oscillatory therapy through an electromedical equipment in improving body contour and appearance of cellulite. SUBJECTS AND METHODS: A prospective and comparative longitudinal clinical study will be performed in 30 women with cellulitis. Patients will be submitted to data collection and evaluation and before and after vibration-oscillatory therapy. HYPOTHESES: Patients are expected to show improvement in body contour and cellulite after vibration-oscillatory therapy. STATISTICAL ANALYSIS: A descriptive analysis will be done before and after vibration-oscillatory therapy, with frequency tables for categorical and descriptive variables (mean, standard deviation, median, minimum and maximum values) for continuous or numerical variables. In order to compare the main variables between the groups and the collection times, the analysis of variance (ANOVA) for repeated measures will be used. Tukey's test will be used to compare the groups. The significance level adopted for the statistical tests will be 5% or p <0.05.
