Active clinical trials for "Syndrome"

PCOS is the most common endocrine disorder in reproductive women. It is estimated that 5 to 10% of women of reproductive age have PCOS. One of the major diagnostic criteria of PCOS was chronic anovulation which lead to irregular menstruation, amenorrhea, and infertility; the other diagnostic criteria was hyperandrogenism which lead to hirsutism, acne and alopecia. Furthermore, PCOS is thought as a metabolic disorder, the long-term consequence of PCOS were diabetes mellitus and cardiovascular disease, which are potentially dangerous in women health. Early diagnosis and prevention is very important to the PCOS patients. Obesity is the most potential risk of threat to health of populations. There is a major impact of obesity on the PCOS related disorders. Insulin resistance and distribution of adipose tissue were thought to be the important risk factors of cardiovascular and metabolic syndrome. To treat PCOS patients properly,Wan-Fang hospital had established a specific medical team. The investigators recently published in "Fertility and Sterility" about the clinical presentation of androgen excess in Taiwanese women. Hirsutism is much less prevalence in Taiwanese PCOS women than that previous reported in the Western women. It is important to know that some clinical presentation of PCOS might have ethic variance. Insulin resistance was reported as another candidate that might have ethic variance.The investigators had reported about 40% women in PCOS women were obese, it is similar with previous literature reported. Obesity is a major factor that could be controlled during the treatment of PCOS.Weight reduction is one of our methods in PCOS treatment. The progressive results for obese PCOS women would be facing the risks of diabetes and metabolic syndrome.The investigators thought like to evaluate the benefit of weight reduction program to the prognosis of obese women with PCOS. Furthermore, it is known that Endothelial progenitor cells (EPC) be an early marker of cardiovascular disease, the investigators would like to know the role of EPC to predict metabolic syndrome in women with PCOS. Wan-Fang hospital has a professional team in PCOS treatment and research which including gynecological endocrinologist, cardiologist, medical endocrinologist, specialist in weight reduction. This team had been working well for more that 4 years. The investigators hope that they can make a contribution to the study and treatment of PCOS in Taiwan.

Introduction: OSAS is an important disease in the actual medic scene. It is important for correlation with chronic cardiovascular disease that leaves an increase in morbimortality and socioeconomic disability to patients with apnea. Objectives: Determinate the correlation between Friedman Classification and the obstructive sleep apnea syndrome (OSAS) gravity through AHI (Apnea Hypopnea Index) in patients with OSAS for surgical indication and evaluation. Materials and Methods: The investigators evaluated and classified 84 patients, in the scale of Epworth, Friedman and how much the gravity of the SAHOS for the AHI.

The EVE-PMS technology is intended for determination of intolerance or sensitivity to sex hormones, among women suffering from severe PreMenstrual Syndrome (PMS). The system includes skin testing panel for identification of hormones to which the patients might be sensitive. Tests are applied close to the ovulation period and the skin reaction is examined in 20 minutes, 48 hours and daily during the following month. Results of skin tests and patient's history will determine the value of EVE-PMS Skin-Test Panel as a diagnostic tool for severe PMS patients.

sRAGE, the soluble form of the receptor for advanced glycation end products, is a novel marker of alveolar epithelial type I cell injury, but is also involved in acute systemic inflammation. The purpose of this observational prospective study is to determine whether sRAGE could be used in an ICU setting as a potential diagnostic and prognostic marker during ALI/ARDS, regardless of associated severe sepsis or septic shock.

The aim of the study is to explore the concept of GnRH-agonist triggering in combination with elective cryopreservation of all 2PN oocytes at larger scale in a pragmatic clinical setting. The question asked is: "Does GnRH-agonist triggering and cryopreservation work", in terms of efficacy and safety, when applied to a larger cohort of patients, and by a number of different centres with different clinical routines.

This study will investigate the sensation that many people with Tourette syndrome (TS) experience before they have a motor tic. It will also test whether blocking the sensation causes the tic to stop. People between 18 and 65 years of age with TS who have at least once tic involving an arm may be eligible for this 3-part study. Those enrolled may participate in all parts or in part 1 or part 2. Those who choose to participate in part 3 must first complete part 2. All must stop taking medication for TS and any other medication that may affect the brain for at least 1 week before the study. Part 1 After numbing the skin or muscles of the arm or leg where a pre-tic sensation is experienced, the response of the nerves will be tested by asking subjects to rate the strength of the sensation after a pinprick and by stimulating the nerves with small electrical shocks. Then, over the course of approximately one hour, subjects will report pre-tic sensations while their motor tics are counted. The onset of each tic will be identified with EMG, a test using electrodes on the skin to indicate the activity of the muscles. Part 2 Subjects brain waves are recorded using magnetoencephalography (MEG) while they are experiencing tics andpre-tic sensory experiences. MEG is a test that records magnetic field changes produced by brain activity. Subjects sit in a chair under a dome containing magnetic field detectors. They watch a clock and report the time a sensory experience starts. Tics are recorded with EMG. Later, a standard MRI of the brain (scan using a magnetic field and radio waves) is done to see which parts of the brain produced the activity recorded with MEG. Part 3 Repetitive transcranial magnetic stimulation (rTMS) is used to try to stop the pre-tic sensations. For TMS, the subject sits in a chair. A wire coil is held on the subject s scalp, and a brief electrical current is passed through the coil, creating a magnetic pulse that stimulates a region of the brain. The goal of this stimulation is to reduce the sensory experience that precedes a tic in one region of the body. During stimulation, the subject hears a click and may feel a pulling sensation on the skin under the coil. There may be a twitch in the muscles of the face, arm or leg. This study uses a pattern of repeated pulses delivered in short bursts. Following each train of pulses, the effect of the stimulation on sensation will be tested by asking the subject to rate the strength of a pinprick and of a vibration. In addition, the nerves are stimulated with small shocks to evaluate the effect of the TMS on nerve activity. To determine the effect of TMS on the pre-tic sensation, subjects are asked to watch a clock and report when they are having a sensory experience. The effect on motor tics will be evaluated by using EMG to indicate the tics.

This study is designed to provide information on feasibility and reproducibility of barostat assessments of colorectal sensory functions and compliance and their pharmacological modulation

Our hypothesis is that altered cardiac sympathetic activity is present and may contribute to the myocardial stunning observed in the apical ballooning syndrome. Aim: Assess the extent and reversibility of cardiac adrenergic neuronal dysfunction using carbon-11 hydroxyephedrine (C-11 HED), a positron emission tomography (PET) tracer, in patients with the apical ballooning syndrome.

We are conducting a large, record-based study to assess the risk of Guillain-Barré Syndrome (GBS), a serious demyelinating disease, following immunization with the tetravalent meningococcal conjugate vaccine (Menactra) that is currently recommended for all adolescents. The study was requested by CDC and FDA because of an unexpected number of case reports to the CDC's Vaccine Adverse Event Reporting System (VAERS). The study protocol was designed by the investigators, with input from FDA, CDC, and the vaccine's manufacturer, Sanofi-Pasteur. An external advisory board that includes CDC representation, provides input regarding important decisions. The manufacturer is not participating in the conduct of the study and has no control over the analysis or dissemination of results. The study is derived from five large US health plans with a total membership of approximately 50 million over the study time period. America's Health Insurance Plans (AHIP) serves as liaison between the health plans and the Coordinating Center at the Department of Ambulatory Care and Prevention of Harvard Medical School and Harvard Pilgrim Health Care, and is the contracting organization with the health plans.

To demonstrate that a strategy of fast genetic testing performed in outpatient clinic allows to select adequately one of the 2 antiplatelet treatments approved in the same indication (ACS with PCI - prasugrel 10mg MD or clopidogrel 75mg MD). Patients will reach similar levels of platelet inhibition with the 2 different thienopyridines suggesting optimal risk/benefit ratio in most patients with individualized therapy.
