Filter by:The objective of this study is to evaluate the clinical efficacy of a prophylaxis paste containing 10% arginine bicarbonate on dentinal hypersensitivity reduction when applied as a pre-procedure to a professional dental cleaning.
The purpose of this study is to evaluate the endoscopic diagnostic options of the endomicroscopy in patients with food intolerance.
The goal of this study is to determine whether Trichuris suis ova, a potential immunomodulator, is safe in adults and children allergic to peanut or tree nuts.
Nowadays, commercial wheat extract is widely accessible, and is used for skin prick test for wheat allergy. However, commercial wheat extracted for skin prick test have less precise test result compared to extract from omega-5 gliadin, which is one of the major allergen with immediate wheat allergy.
This study is for patients who have been diagnosed with either a Patent Foramen Ovale [PFO] or an Atrial Septal Defect [ASD]. These are a type of hole located in the wall that separates the top two (2) chambers of the heart. You have been recommended to receive an atrial septal occluder device [a device specifically designed to close PFOs and ASDs] implanted in your heart to close this hole. Because these devices are made of materials that contain nickel, this trial is being conducted to perform blood nickel tests on those patients already referred for an atrial septal occluder device such as yourself. The purpose of this study is to compare levels of nickel in the blood in patients receiving either the Amplatzer or the Helex devices.
The purpose of the study is to confirm the clinical effectiveness and safety of topical diammine silver fluoride (DASF) as a tooth desensitizer in adulst by comparing it to the application of sterile water. The study will be conducted in two different sites in Peru. Participantes will be 144 adults who will have at least one vital maxillary or mandibular cuspid or premolar with a cervical defect on the buccal surface and clinical hypersensitivity in response to air. Subjects will be randomly assigned to a topical application of DAS or sterile water. The reduction of pain (sensitivity) using a 100 mm VAS, will be determined. Safety will be also determined by evaluating the gingival condition (erythema, white changes, ulceration, staining) before and ater the application of the products. The evaluation times will be 24 hours and 7 days.
Type 2 diabetes is a major public health problem in India with an estimated a prevalence of approximately 4% and 12% in rural and urban areas respectively. Accumulating evidence suggests that serum cholecalciferol levels may be inversely related to the prevalence of diabetes, insulin resistance and metabolic syndrome. The trials available on the effect of Vitamin D supplementation on insulin/glucose metabolism have been conducted using small sample sizes in different subgroups document variable results (significant decrease in HbA1c concentration with insulin concentration in hemodialysis patients; insulin levels lower with oral Vitamin D in gestational diabetes; no effect of Vitamin D on serum insulin levels in post menopausal women). A double blind randomized controlled trial conducted at our institute using 3,60,000 IU of cholecalciferol over 6 weeks documented improvement in OGIS index of insulin sensitivity. We therefore, plan to study the long term effect of vitamin D supplementation on peripheral insulin sensitivity.
Tooth sensitivity reduction after dentifrices use
In this study, patients with relapsed or refractory ovarian cancer will receive treatment with pazopanib and liposomal doxorubicin (Doxil) until disease progression or unacceptable toxicity occurs. The Phase I portion will define the dose limiting toxicity (DLT) of pazopanib and liposomal doxorubicin when administered in combination. Once the maximum tolerated dose has been identified in the Phase I portion, the Phase II portion will evaluate efficacy and safety of this combination in the same patient population.
In this clinical study we aim to determine the effect of allergy immunotherapy in decreasing asthma and allergy related disease in children who had multiple episodes of wheezing and who are at high risk for developing persisting asthma. These risks include a history of asthma in the parents, allergies to environmental allergens (such as dust mite, cockroach or mouse) and other allergic diseases such as eczema or food allergies. Allergy Immunotherapy is not new and has been practiced for many years to treat asthma and environmental allergies in older children and adults, but has not yet been systematically studied in young children.
