There are about 5012 clinical studies being (or have been) conducted in Mexico. 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 aim of this study is to determine the effect of imaging angle on the measurement of fetal cisterna magna (CM) in the second trimester. Fetal CM will be prospectively measured in women at 18-24.6 weeks' gestation. Measurements will be made on different angles between the transducer and fetal cerebellar axial plane with internal landmarks. Design: Observative, cross sectional

Goal:To compare the efficacy of the ophthalmic solution of pazufloxacin 0.6%, against the ophthalmic solution of gatifloxacin 0.3%, in the treatment of acute bacterial conjunctivitis. Hypothesis:the ophthalmic solution PRO-157 is not inferior in the treatment of bacterial conjunctivitis, compared to the ophthalmic solution of gatifloxacin 0.3%, by means of the clinical remission of the disease. Number of patients: 160 patients, each one will provide an eye for efficacy analysis, divided into 2 groups (80 eyes per group).
International, post-authorisation non-interventional study to evaluate real-life effectiveness, safety and utilisation patterns of Octapharma's FVIII concentrates Nuwiq, Octanate, and Wilate in previously untreated and minimally treated severe haemophilia A patients in routine clinical practice.
objective: To evaluate the efficacy of the ophthalmic emulsion PRO-145 in the treatment of inflammation and pain after phacoemulsification. Hypothesis: The use of the ophthalmic emulsion PRO-145 is effective in decreasing the inflammatory response evaluated by means of cellularity in the anterior chamber, after phacoemulsification. Methodology: Phase III clinical trial, double-blind, controlled, parallel group, multicentre, randomized. Number of patients: 178 subjects divided into 2 groups (89 subjects per group), who will provide an eye for the evaluation of efficacy. Diagnosis and main inclusion criteria: Diagnosis: Postoperative phacoemulsification and foldable intraocular lens placement in a bag.
Chronic hepatitis C infection (CHC) is usually asymptomatic; nevertheless, there are studies that show that up to two thirds of patients may present some type of extrahepatic manifestation. The most frequent extrahepatic manifestation is type II mixed cryoglobulinemia (MCG-II) and clinically the most common presentation is leukocytoclastic vasculitis (LCV) with palpable purpura that affects the lower extremities. It is estimated that up to 80% of MCG-II cases are due to CHC. Also, previous studies have demonstrated that CHC prevalence is higher in patients with autoimmune diseases compared with general population. Therefore, if vasculitis is an extrahepatic manifestation of CHC, then the prevalence of CHC infection in this group of patients could be higher than the prevalence reported in general population. The aim of the study is to know the prevalence of CHC, determined by serological rapid test for hepatitis C screening, then all positive cases will be confirmed by quantitative viral load, in patients who consult primarily to a rheumatology department for "vasculitis" or other potential hepatitis C extrahepatic manifestations (rheumatological conditions).
Introduction. Autonomic dysfunction, smooth muscle fibrosis and vascular damage lead to small intestinal bacterial overgrowth (SIBO) in Systemic Sclerosis (SSc). SIBO is characterized by diarrhea, abdominal pain, bloating, malabsorption and malnutrition. Aim. To evaluate the efficacy and safety of Saccharomyces boulardii in combination with metronidazole for 2 months for reducing gastrointestinal symptoms (NIH-PROMIS) and preventing bacterial overgrowth (hydrogen breath test) versus the standard treatment in patients with systemic sclerosis. Method. Controlled clinical trial conduct in patients with SSc (ACR-EULAR 2015) who signed informed consent. NIH PROMIS®questionarie will be apply to evaluate gastrointestinal symptoms and classify in not symptomatic, least, mildy, moderately and most symptomatic. Glucose HBT will be apply after 14 hours fast, oral hygiene and 30 days free of antibiotics to evaluate SIBO. Patients with negative HBT and symptoms associated to glucose ingestion will repeat test with lactulose. Patients will be aleatorized into 1. Saccharomyces boulardii, 2. Metronidazole and 3. Metronidazole plus Saccharomyces boulardii. All data will be analyzed using SPSS software. It will be used parametric statistics for normally distributed variables and nonparametric statistics for free distribution.
Pneumonia is one of the main causes of morbidity and mortality in the world, especially in developing countries like ours. The National Health and Nutrition Survey of Mexico, in 2006 showed underweight in 472,890 (5%) children under five years, low height in 1,194,805 (12.7%) and wasting in153,000 (1.6%) children. Zinc is decreased in malnutrition and is an essential cofactor for many proteins involved in cellular processes. Zinc deficiency leads to a decrease in the number of T cells, the ratio of Th1 to Th2 cells and the production of Th1 cytokines such as interferon gamma, with alteration in T cell mediated immunity. In malnourished children zinc supplementation restores the immune response. Reports of zinc supplementation in children with pneumonia are controversial. The aims of this study are to evaluate the immunomodulatory effect of zinc supplementation in the clinical course of children with pneumonia, to evaluate the lymphoproliferative and cytokine response in these children and to explore whether the viral or bacterial etiology is related to the clinical response to supplementation with this micronutrient. A clinical, randomized, prospective, controlled, double blinded study will be carried out. Children from 1 month to 5 years of age will be included, with the clinical and / or radiological diagnosis of pneumonia that enter the emergency room of the participant institutions. Empirical treatment for pneumonia will begin and each patient will be randomized 1:1 in 2 groups. One will receive zinc supplementation and another a placebo (glucose). Samples will be taken to determine the etiology (nasal lavage for multiplex polymerase chain reaction for 16 respiratory viruses and 6 bacteria) and a blood sample to measure the cytokine pattern and the lymphoproliferative response. After 7 days of treatment, a second sample will be taken for immunological studies (cytokine pattern and lymphoproliferative response). The following parameters will be measured to evaluate the clinical evolution: respiratory rate, temperature, oxygen saturation, inability to eat, duration of cough, rales, temperature normalization time, normalization time of oxygen saturation, normalization time of the respiratory rate, hospitalization time and outcome (discharge due to clinical improvement or death). A correlation will be made between the improvement in clinical parameters and mortality in the zinc supplementation group and the probable bacterial or viral etiology.
The objective of this study is to evaluate the effect of cabozantinib compared with placebo on progression free survival (PFS) and objective response rate (ORR) in subjects with Radioiodine-Refractory Differentiated Thyroid Cancer (DTC) who have progressed after prior vascular endothelial growth factor receptor (VEGFR)-Targeted therapy.
