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.
This phase III clinical study will be conducted in Brazilian research sites. It will be included in the study 314 participants diagnosed with primary knee OA according to the classification criteria of the ACR. After a washout period, the participants will be randomized to receive the combination of glucosamine sulfate + chondroitin sulfate of bovine origin of Eurofarma Laboratorios S.A. (N= 157) or the combination of glucosamine sulfate + chondroitin sulfate of Zodiac Pharmaceuticals S.A. Condroflex ® (N = 157). The treatment period of the study will be of 24 weeks. Each participant will perform seven visits to the research site. The main evaluations will be the improve of pain in the target knee by questionnaire Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and quality of life by SF-12 questionnaire.
Introduction: Osteoarthritis of the knee is a very common disease. However there are few treatment options for these patients. Botulinum toxin type A is an option for chronic pain. If the investigators prove effectiveness of its use for intra-articular analgesia, Botulinum toxin type A can be useful for treat these patients. Objective: Compare the effectiveness of the use of intra-articular corticosteroid versus Botulinum toxin type A in the treatment of patients with knee osteoarthritis. Methods: A prospective controlled randomized double blind studied with three groups (n = 35 each group) of patients with symptomatic osteoarthritis of the knees receive intra-articular medication in a single moment will be undertaken. The three groups will be: Botulinum toxin type A Group: patients who receive 100 units of botulinum toxin; hexacetonide of triamcinolone Group: patients who receive 40mg of triamcinolone hexacetonide, and saline group: patients who receive 2ml of normal saline. Patients will be assessed by evaluators " blind " in 4 times during 12 weeks of follow-up with clinical assessment instruments (pain, quality of life questionnaire as short form 36 questionnaire) , functional ( WOMAC questionnaire) , and ultrasound (quantitative and semi quantitative measure of synovial hypertrophy and semi quantitative Power Doppler ) .The following statistical tests will be used : Student's t test, Mann - Whitney , chi- square test and ANOVA for repeated measures . Will be considered as statistical significance the difference of 5 %.
The aim of the study is to demonstrate the safety and efficacy of the TCD-10023 (Ultimaster) sirolimus eluting stent in patients with acute ST-elevation myocardial infarction (STEMI), by proving superiority with respect to in-stent late loss at 6 months to the Kaname bare metal stent and non-inferiority with respect to Target Vessel Failure (TVF) at 12 months.
The study aims to analyze the immediate effects and 72 hours after application of the Kinesio Taping (KT) in the electromyographic activity of the vastus medialis oblique (VMO) and vastus lateralis (VL), the isokinetic performance of the quadriceps and referred pain of subjects with PFPS. The volunteers will be randomly assigned to one of the three groups and perform one of the protocols: control - remain at rest; KT - application of Kinesio Taping with tension in the VMO region; placebo - application of Kinesio Taping without tension, in the same region. All volunteers will be submitted to the evaluation of pain intensity, the electromyographic activity of the VMO and VL and dynamometric parameters in 3 times: before the application of KT, immediately after the application of KT and after 72h of application. Average effect estimates (differences between groups) for all variables will be calculated using the mixed model ANOVA with a significance level of 5% (p ≤ 0.05).
This project is one of four components of a thematic project that aims to evaluate the use of ultrasound in regional and infiltration blocks, called "Use of ultrasound in regional blocks and infiltration for the treatment of acute and chronic pain". It aims to evaluate quantitatively and qualitatively the knee pain control in patients with osteoarthritis after neurotomy by saphenous nerve radiofrequency guided by ultrasound , compared to neurotomy by radiofrequency of genicular nerves guided by fluoroscopy . Differences between total consumption of analgesics, side effects of medications , impact on quality of life and functional capacity in patients undergoing saphenous nerve neurotomy by radiofrequency guided by ultrasound compared to neurotomy by radiofrequency of genicular nerves guided by fluoroscopy, will also be evaluated.
The main purpose is to compare the detection rate of 20-core versus 12-core prostate biopsy. The secondary objective is to evaluate pain perception using a validated scale to compare the analgesia provided by the two different local anesthesia schemes. Data will be prospectively collected from patients who will undergo prostate biopsy in a single high volume urology center. The patients will be randomized to two different biopsy samplings and two local anesthesia schemes.
Objective: Assess the effect of caffeine in the following vestibular function tests: Cervical Vestibular Evoked Potential (cVEMP), Ocular Vestibular Evoked Potential(oVEMP) and Caloric Test. Methods: Randomized, prospective triple-blind, placebo controlled clinical trial. All participants underwent otoscopy, tympanometry, responded to the Profile of Mood State (POMS), submitted to the cVEMP, oVEMP and caloric tests. After that they received placebo or caffeine capsule (300mg) and repeated the procedures 45 minutes after.
This randomized clinical trial evaluated the effectiveness of supplemental photodynamic therapy (PDT) in optimizing the removal of bacteria and endotoxins from primarily infected root canals after one-visit and two-visit treatments.Twenty-four primarily infected root canals with apical periodontitis were selected and randomly divided into one-visit (n=12) and two-visit treatments (n=12). Chemo-mechanical preparation (CMP) was performed by using the single-file reciprocating technique + 2.5% NaOCL and a final rinse with 17% Ethylenediamine tetraacetic acid (EDTA). The photosensitizer agent (methylene blue 10 mg/mL) was applied to root canals for 60 seconds and submitted to laser with a potency of 60 milliwatts (mW) and energy density of 129 J/cm2 for 120 seconds after CMP in the one-visit treatment and after 14-day inter-appointment medication with Ca(OH)2 + saline solution (SSL) in the two-visit treatment. Samples were collected before and after root canal procedures. Endotoxins were quantified by chromogenic limulus amebocyte lysate assay. Culture techniques were used to determine bacterial colony-forming unit counts.
Laugh is more than visual and vocal behave, is always followed by a series of physiological changes, including contractions of musculoskeletal system, increase of cardiac frequency by catecholamine release and hyperventilation that promoves the increase of maximum breathing and oxygen saturation. Laugh therapy may be an alternative therapy, simple, and improve the quality of life of individuals can influence physiological and biochemical parameters of the human body.
The purpose of this study is to assess the effect of pulmonary rehabilitation on the transport of secretions, inflammation and respiratory resistance, and its repercussions on the quality of life in patients with bronchiectasis.
