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.
The purpose of this study is to determine the reason patients are deficient in nutrients intake such as antioxidants vitamins.
"Phase III Clinical Trial for American Tegumentary Leishmaniasis: Comparison of Standard and Alternative Antimonial Dosage in Patients With American Cutaneous Leishmaniasis " has begun in October 2008 at the Laboratory of Leishmaniasis Surveillance at Evandro Chagas Clinical Research Institute (IPEC), FIOCRUZ, aiming to compare efficacy and safety of the standard recommended schedule with an alternative dosage scheme of meglumine antimoniate in the treatment of American tegumentary leishmaniasis (ATL). It is a study with blind evaluation by the doctors and the responsible for statistical analysis. Patients diagnosed with ATL, eligible for the trial are randomly allocated into one of the schemes with meglumine antimoniate and monitored before, during and after it. There is no single regimen applicable to all forms of leishmaniasis around the world. Therapeutic regimens applied to treat people living in other geographic areas result in mixed outcomes. Ideally, the most appropriate regimens should be established for each endemic area, based on its efficacy, toxicity, difficulties of administration and cost. Given the problems and limitations of the use of pentavalent antimonials (Sb5+) at 20 mg Sb5+ / kg / day, less toxic alternative regimens, i.e. 5mg Sb5+/kg/day, deserve to be better evaluated. The treatment of ATL must heal skin lesions and prevent late mucosal lesion development. The indication of high doses of Sb5+ is based on the evidence that there could be induction of resistance with use of subdoses. However, clinical studies with extended follow-up in Rio de Janeiro have suggested that regular low doses (5mg Sb5+ / kg / day) may constitute an effective scheme, achieving cure rates similar to higher doses, with lower toxicity, ease of implementation and lower cost. Published studies on efficacy and safety of alternative dosage schemes with meglumine antimoniate failed to provide conclusive results so far, for various methodological biases. The need to compare the effectiveness and safety between the standard treatment scheme with meglumine antimoniate currently recommended in Brazil for the treatment of ATL and an alternative scheme with low doses of antimony is the motive for this study in Rio de Janeiro.
The aim of this study was to determine if the addition of ketamine reduces remifentanil-induced hyperalgesia, improves its analgesic effect, inhibits IL(interleukin)-6 and IL-8 (inflammatory cytokines), and stimulates IL-10 (an anti-inflammatory cytokine).
Perhaps the use of a more selective anti-inflammatory drug, capable of inhibiting enzyme specific for pain may be more effective in preventing the tooth sensitivity caused by the inflammatory response produced by in-office bleaching. To the extent of the authors´ knowledge, no study has so far addressed the use of a selective anti-inflammatory drug specific for pain enzyme on tooth sensitivity, being this the aim of the present investigation.
This study aimed to evaluate the acute physiological effects of expiration with the glottis open in lateral posture (ELTGOL) and Flutter valve in dynamic and static lung volumes in patients with bronchiectasis and, secondarily, to study the effect of these techniques in sputum production.
The purpose of this study is to examine the effect of a pharmaceutical care program on the level of glycated hemoglobin for hyperglycemic users of brazilian public health care system in drug treatment for type 2 diabetes.
Chronic Obstructive Pulmonary Disease (COPD) leads to a reduction in exercise capacity that affects the quality of life and increases mortality of these patients. So, exercise tests are considered as an essential component of the clinical evaluation of the patients with COPD. The objective of this study is to evaluate the reproducibility sensitivity and validity of the Six Minute Step Test (6MST) in patients with COPD and in health volunteers, and verify its relation with the "Body-Mass Index, Airways Obstruction, Dyspnea and Exercise Capacity" Index (BODE). This Observational, Transversal, Prospective study will be conducted in the "Special Unit of Respiratory Physiotherapy", of the "Federal University of São Carlos". To participate in this study, 120 subjects, both gender, will be invited and will be allocated in five groups: Group I (30 healthy young subjects of 17 to 27 years old), Group II (30 healthy elderly individuals of 60 to 75 years old), and patients COPD, 60 to 80 years old, with mild, moderate, severe and very severe obstruction determined by the forced expiratory volume in one second (FEV1) by forced vital capacity (FVC) relation "FEV1/FVC" <70% and FEV1 in predict percentage < 80% composing the Group III (20 COPD patients in GOLD stage I), Group IV (20 COPD patients in GOLD stage II) and Group V (20 patients COPD stages III and IV). All subjects will be submitted to body composition and anthropometric assessment, pulmonary function test, three 6-minutes walk test (6MWT) and three 6MST. Furthermore, the patients of the groups III, IV and V will answer the Modified Medical Research Council (mMRC) scale, and BODE index will be calculated to each of them.
Mesenchymal stem cells have been tested in many autoimmune disorders with encouraging results and may be an alternative to the treatment of immune-mediated severe acquired aplastic anemia.
This study evaluates the diffusion area (cephalic, lateral, medial and caudal points) of the botulinum toxin type A in the frontal muscle for usual concentrations and dilutions of the drug. A basal line control and After the application control will be made, and the investigators will evaluate the drug effects, based on clinical aspects, photographic registers and through electromyography exam (EMG). Considering the results of our investigation, the investigators may propose a pattern of application of BOTULINUM TOXIN TYPE-A Botox® in the frontal area.
This prospective controlled trial was designed to determine whether breast reduction may influence physical activity and sexuality of breast hypertrophy women.
