Active clinical trials for "Syndrome"

The purpose of the project is the determination of how the deletion of DNA from chromosome 22 at the q11.2 band causes the phenotypes observed in velo-cardio-facial syndrome (VCFS). In other words, the purpose remains genotype-to-phenotype matching. Current methods includes the use of whole genome chips and microarray analysis. Blood samples are collected for DNA from every patient who consents from the VCFS Center at Upstate Medical University. They are examined for phenotypic features consistent with our typical clinical evaluation. The information from these examinations will be entered anonymously into a database. Genomic information is then matched to clinical phenotype with appropriate statistical method applied.

The purpose of this study is to compare the central corneal thickness measurement in patients with exfoliation syndrome, exfoliative glaucoma, primary open-angle glaucoma, ocular hypertension and normal controls and to evaluate the value of corneal thickness in the diagnosis and management of glaucoma.

The purpose of this study is to correlate phenotype and genotype of Down syndrome patients in order to identify the biochemical reactions involved in their mental retardation and their other phenotypic characteristics.

West syndrome (WS) is a specific type of epilepsy (or seizure disorder) that has three features: infantile spasms (type of seizure), loss of milestones, and a specific pattern on electroencephalogram (EEG or brain wave test) called hypsarhythmia. The purpose of this study is to detect pre-hypsarhythmia in infants at high-risk for WS and determine whether treatment with ACTH will prevent WS.

Symptoms of Neonatal Abstinence Syndrome (NAS) can be attributed largely to dysfunction of the autonomic nervous system in opiate exposed neonates. Vagal tone is a readily available measure of autonomic nervous system functioning. NAS is a widely variable disorder with poorly understood pathophysiology; while all opiate exposed infants will exhibit some signs and symptoms of NAS, only approximately ½ have severe enough symptoms to require pharmacologic therapy. This research seeks to determine the relationship between infant vagal tone and NAS severity. The determination of a link between newborn vagal tone and NAS severity could result in the prediction of infants at risk for severe NAS and provide these infants and mothers with intensified services and early treatment, thereby shortening the course of NAS in the infant.

The proposed study is a Cross-sectional epidemiological study, performed in 330 primary care practices in Germany. The study will be conducted on a fixed day in November 2007. Primary care surgeries throughout Germany will be asked to take part. The study material will be delivered to the surgery by a member of sales-force who will also explain the study conduct to the physician/staff. Physicians who want to take part in the study will send a signed contract to BI. Physicians will be trained to diagnose RLS. All patients attending the participating surgeries on a fixed day will be invited to participate in the study. The patients will be handed a questionnaire to fill out while waiting for their appointment. No patient-related data apart from gender and year of birth will be recorded on the questionnaire and it will be ensured that no re-identification of patients is possible. Therefore, no written informed consent will be obtained from the participants. The patient questionnaire will consist of the following items: A screening questionnaire for RLS (according to Stiasny-Kolster et. al., data on file) Additional questions concerning the impact of the patients leg problems on daily life. The practice staff will then collect the questionnaire. All patients who have answered question 1 (asking for unpleasant sensations of the legs) with ¿Yes¿ will subsequently be assessed for the diagnosis by the physician. The physician fills out a second questionnaire, covering the following items: Diagnosis (cause of leg problems) Concomitant diagnoses and therapies If the diagnosis of RLS was made: consequences (therapy)? Was the diagnosis of RLS pre-known? All completed questionnaires will be sent to data management by the surgery within 2 working days.

The purpose of the study is to procure blood samples from patients who present to the Emergency Department with suspected ACS (Acute Coronary Syndrome).

The purpose of the study is to find and follow-up the metabolic syndrome parameters on patients administering atypical antipsychotics.

ARDS (Acute Respiratory Distress Syndrome) is a condition of severe inflammation and excess fluids in the lungs that impairs their function of oxygen uptake to the point of needing a ventilator (breathing machine) to help them obtain enough oxygen into the body. Because of the high amounts of gas that the ventilator has to give to these patients, high pressures may develop deep into the lungs and produce complications for the patient. However, physicians sometimes cannot recognize it because it requires special equipment to measure pressure deep in the lungs. The goal of this study is to determine if the amount of this pressure can be calculated using mathematical formulas and the routine numbers provided by ventilators. The study consists on making the conventional measurement of this deep pressure and at the same time calculate this same pressure from other measurements that the ventilator routinely provides, to see if the calculated value can replace the more complicated conventional measurement. The measurements will be done by: placing a small device along the tubing connecting the patient to the ventilator; giving medicines to relax the muscles (if the patient is not already receiving them); and making the ventilator hold the patient's breath for a few seconds to take measurements. This is repeated after the breathing rate of the ventilator is increased or decreased mildly. Risks related to the medicine to be used and the measuring maneuvers are rare but include transient narrowing of windpipes, transiently low heart rate, blood pressure or blood oxygen, and allergic reactions. This is not a treatment. The information obtained during the study will be shared with the treating doctors who may find it useful to make adjustments to the ventilator. The patient may receive no direct benefit from being in this study; however, the findings may contribute to better care for this kind of patients in the future.

Prader-Willi syndrome (PWS) is a genetic disorder characterized by childhood-onset obesity and endocrine dysfunction that leads to cardiovascular disability and early death within the first 3 decades of life.To assess the significance of risk factors for future disabilities, carotid artery intima-media thickness (IMT) was measured and correlated with known atherosclerotic risk factors in 27 children with PWS and 24 age-, sex-, and body mass index (BMI)-adjusted controls.
