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.
It aims to evaluate the efficacy of the chamomile recutita gel and urea cream in the prevention of radiodermatitis in patients with breast cancer or head and neck cancer undergoing radiotherapy. Prophylactic Trial will consist of a control group and two experimental groups, namely control group (usual care), Experimental Group 01 (usual care + topical application of the gel C. recutita) and Experimental Group 02 (usual care + topical application of Urea based cream). The doses used in the different compounds are being in test since february 2014 by a dose-response curve study, using 6 groups with three doses of urea cream and three doses of C. recutita gel. The study will be conducted at the Center for High Complexity Oncology at University Hospital of Brasília (CACON/HUB), Brazil. The degree of radiodermatitis is evaluated weekly, according to established criteria to classify the effects of radiotherapy, which identifies grades 0, 1, 2 , 3 and 4, according to the score of the Radiation Therapy Oncology Group - RTOG. To evaluate the skin reaction will also be applied scale Common Terminology Criteria for Adverse Events (CTCAE) and Radiation-Induced Skin Reaction Assessment Scale (RISRAS).
This study will evaluate the efficacy and safety of bimatoprost SR in participants with open-angle glaucoma or ocular hypertension. The study includes a 12-month treatment period with an 8-month extended follow-up.
The purpose of this study is to determine if the addition of intermittent positive airway pressure breathing (specific lung expansion technique) to conventional chest physiotherapy chest drainage is effective to accelerate the reabsorption of pleural effusion and consequently decrease the duration of chest tube drainage and respiratory system impairment. These effects would decrease hospital stay lengths and the incidence of pulmonary complications.
This study aimed to investigate the influence of uncontrolled type 1 and type 2 diabetes mellitus (DM) on the kinetic disposition, metabolism and pharmacokinetics-pharmacodynamics of tramadol enantiomers in patients with neuropathic pain. Thus, nondiabetic patients (control group, n = 12), patients with type 1 DM (n = 9), and patients with type 2 DM (n = 9), all with neuropathic pain and phenotyped as extensive metabolizers of cytochrome P450 2D6 (CYP2D6) who were treated with a single oral dose of 100 mg racemic tramadol were investigated.
Background: Preoperative Anxiety is a negative factor in anesthetic and surgical experience. Among the strategies for reducing children's anxiety, non-pharmacological strategies are as important as the pharmacological ones, but their its validity is still controversial. Objectives: The aim of this study is to verify if the information provided to relatives as well as and smartphone application provided to children interferes in prevalence and level of child preoperative anxiety. Methods: Eighty four children, 4-8 years old, ASA I, II and III, undergoing elective surgical procedures and their relatives are randomly allocated into four groups: control group (CG) where the relative received conventional information about anesthesia; info group (IG), relative received an information leaflet about anesthesia; device group (DG), relative received only conventional verbal information and the child received smartphone application immediately before entering the operating room; device and info group (DIG) relative received a leaflet containing information and the child received smartphone application. Children's anxiety will be assessed using the modified Yale Preoperative Anxiety Scale (m-YPAS) on three occasions: at the ward (W), surgical theater in the waiting room (WR) and at the operating room (OR). Statistics analysis will employ by Kruskall-Wallis and Mann-Whitney tests for prevalence and level of anxiety in the groups.
The purpose of this study is to verify the effect of anteroposterior talus mobilization on range of motion, pain, and functional capacity in participants with sub-acute and chronic ankle injuries.
Background: 5% 5-fluorouracil cream (5-FU) is a well-established treatment for actinic keratosis (AK) and ingenol mebutate gel (IMB) is a new topical field therapy. Objective: To compare tolerability and safety of IMB with 5-FU for the treatment of facial AKs. Methods: Open-label, prospective, randomized, controlled clinical trial with 100 patients with AKs within 25-cm2 contiguous field on the face. IMB was applied daily for three consecutive days. 5-FU was applied twice a day for four weeks. Treatment effect was evaluated at baseline and on days 2, 3, 4, 8, 15, 22, 29, 36 and 43, considering ITT populations.
The purpose of this study is to compare the clinical outcomes after coronally advanced flap technique (CAF) associated or not to a porcine collagen matrix graft (CM) in the treatment of single gingival recessions. For this blinded randomized controlled clinical trial, 40 patients with Miller Class I or II gingival recession ≥ 2 mm in canines or premolars will selected and randomly assigned to receive either CAF or CAF+CM. The clinical parameters evaluated will be probing depth, clinical attachment level, gingival recession height, height and thickness of keratinized tissue. Clinical measurements will be taken at baseline and 45 days, 2, 3 and 6 months after surgery.
This study is conducted to test the hypothesis that in uncontrolled type 2 diabetic adults treatment with diacerein will improve glycemic control and will reduce liver fat within a 24 month period.
This survey is conducted in South America. The purpose is to identify the key psychosocial issues affecting patients with haemophilia.
