Filter by:The overall significance of this study is to develop a laboratory developed test (LDT) to use a new marker in the maternal blood to better identify pregnancies that have a child with a chromosome abnormality such as Down syndrome (trisomy 21), Edward's syndrome (trisomy 18), Patau syndrome (trisomy 13), Klinefelter syndrome, (47, XXY), and other chromosome abnormalities. Accomplishing that task would reduce the need for invasive amniocentesis and CVS procedures.
The purpose of this study is to assess the efficacy of pregabalin in patients with complex regional pain syndrome Type I and to determine whether it provides clinically significant pain relief and whether it improves functioning of the upper limb.
The purpose of this study is to study the effect of two doses of olmesartan medoxomil and amlodipine on vascular markers in hypertensive patients with metabolic syndrome.
This phase I trial studies the side effects and the best dose of sunitinib malate in treating human immunodeficiency virus (HIV)-positive patients with cancer receiving antiretroviral therapy. Sunitinib malate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor.
The CIRAS study will investigate postmenopausal breast cancer patients with hand pain and compare those receiving aromatase inhibitors (cases) to breast cancer patients with hand pain not receiving aromatase inhibitors (controls) in order assess whether this syndrome is an inflammatory arthritis.
Background: - Urticaria is a common itchy skin disorder that may occur spontaneously or on exposure to a physical trigger (called physical urticaria). - Researchers are studying the genetic basis of a physically induced urticarial syndrome. Once called familial cold urticaria, this condition is now called familial cold autoinflammatory syndrome (FCAS). FCAS is an autoinflammatory disease, a group of inherited disorders characterized by unprovoked episodes of inflammation. Patients with FCAS often have hives, joint pain, and fever following general exposure to cold. - Patients with FCAS have a mutation in a gene that makes a protein called cryopyrin. Cryopyrin seems to be involved with the production of a proinflammatory mediator called interleukin-1 (IL-1). Patients with FCAS and others with autoinflammatory syndromes have benefited from medication that blocks the effects of IL-1. Objectives: - To investigate mechanisms that may cause physical hives or urticaria. - To reproduce urticaria through challenge testing (procedures to test the skin for a reaction to a stimulus), followed by mast cell studies, measurement of IL-1, genetic studies, and other molecular studies to lead to a better understanding of urticaria and to design safe and more effective treatments. Eligibility: - Patients between 6 months and 65 years of age with a documented history of clinically reproducible physical urticaria that triggers hives and that has been evaluated by a physician. Patients should have a letter of referral, including copies of pertinent medical history and laboratory studies, from a referring physician. - Affected and nonaffected family members of such patients. - Exclusion criteria include (1) the presence of conditions that may put the subject at undue risk, such as acute infection, severe thrombocytopenia (a lower than normal number of platelets in the blood), or significant cardiovascular disease; (2) any condition that would make the subject unsuitable for enrollment in this study; and (3) a history of HIV, other known immunodeficiency, or evidence of chronic Hepatitis B and/or C infection. Design: - Researchers will conduct the following tests to verify which triggers cause the hives: - History and physical exam to determine the relationship between the trigger and appearance of the hives. - Blood samples for baseline screening (additional samples may be taken within 8 hours of triggering hives). - Verification of hives using standard challenge testing. - Procedures to trigger urticaria (the challenge testing) include dermatographism (stroking the skin), delayed pressure urticaria (direct pressure), cold-induced urticaria (cold exposure), cholinergic urticaria (exercise, hot water), solar urticaria (sun exposure), localized heat urticaria (direct heat exposure), aquagenic urticaria (room temperature water), and vibratory angioedema (direct vibratory stimulus exposure). - Participants who have a positive history for hives and failed challenge testing (that is, hives resulted from the triggers) will be asked to provide a skin biopsy and additional bloods samples for research purposes. - Participants will be asked to return to the clinic within 1 month if multiple triggers could not be verified during the initial visit, or to return for additional research evaluations, which may include a skin punch biopsy and blood sample collection. Patients may have to stay at the hospital overnight, if required to document the disease. - Nonaffected family members who enroll in this protocol will provide samples for comparison with the family member who has a history of hives. - Participants will receive a small financial compensation for the skin biopsy.
The main goal of this open-label, prospective, non-controlled, non-interventional post marketing surveillance study is to evaluate how pramipexole treatment works when applied in actual practice. In actual practice patients who would have been excluded in the clinical registration studies of pramipexole in moderate to severe primary Restless Legs Syndrome (i.e. those with certain disease histories, co-morbidities and/or demographic characteristics) will also be treated with pramipexole. Thus, during this post marketing surveillance study additional information on the efficacy and safety of pramipexole in those patients will be obtained. The objectives of this post marketing surveillance study are: - To investigate the influence of Sifrol® (pramipexole) treatment on unpleasant sensory symptoms of Restless Legs Syndrome as measured with the short form of the McGill Pain Questionnaire. - To assess if improvement of sensory symptoms correlates with overall Restless Legs Syndrome severity (International Restless Legs Syndrome Scale for Severity) and with secondary symptoms like sleeping problems and daytime tiredness (items 1 & 6 from Restless Legs Syndrome-6). - To evaluate if the treatment effect of Sifrol on overall Restless Legs Syndrome severity (International Restless Legs Syndrome Scale for Severity) differs between patients with high pain scores and patients with lower pain scores. - To compare General Practitioner and neurologist sites patient populations in terms of demographics, Restless Legs Syndrome severity at Visit 1 and treatment outcomes at Visit 3. - To evaluate the development of behavioural changes under pramipexole treatment.
The purpose of the study is to determine whether anticoagulant use (i.e. salicylates, clopidogrel, low-molecular weight heparin, or coumarin derivates) is able to prevent the development of the sinusoidal obstruction syndrome secondary to oxaliplatin-based neoadjuvant chemotherapy in patients suffering from colorectal liver metastases.
Wiskott-Aldrich syndrome (WAS) is a rare X-linked congenital immune-deficiency syndrome and hematopoietic stem cell transplantation (HSCT) has become a curative modality. But the transplant with the conventional conditioning resulted in high incidence of treatment related toxicities and non-myeloablative conditioning resulted in high incidence of engraftment failure. Recently, fludarabine based reduced toxicity myeloablative conditioning regimen was developed for adult myeloid malignancies with promising result of good engraftment and low treatment related toxicities. To increase the engraftment potential without serious complication, reduced toxicity myeloablative conditioning regimen composed of fludarabine, busulfan, and thymoglobulin is designed for Wiskott-Aldrich syndrome.
Obesity is considered as the epidemic of the century. Central obesity is one of the metabolic syndrome's features. It has been proven that obesity can cause back pain and headaches; thus, there might be a link between chronic pain and the syndrome. The objective of this study is to assess the prevalence of metabolic syndrome in patients suffering from chronic pain.
