Active clinical trials for "Syndrome"

The purpose of this study is to assess long term (1 year) respiratory sequelae in children surviving an acute respiratory distress syndrome

The purpose of this study is to characterise the clinical features, histopathology and the treatment outcomes of patients with idiopathic orbital inflammation syndrome.

The goal of the project is to identify and clone the gene(s) responsible for the Alagille Syndrome (AGS) by a positional cloning approach. The first step towards this goal is to define the smallest genomic candidate region for AGS at 20p12 and to begin to identify genes within this region which are, by definition, candidate genes for the disease. In a collaborative effort with clinician-investigators studying the Alagille syndrome, metaphase chromosomes and genomic DNA from affected individuals will be studied for subchromosomal deletions and for mutations in the candidate genes. Characterization of genes involved in Alagille syndrome could provide important insight into the pathophysiology of the disease, the development of normal liver and treatment of this disease. Recently, we and others found that mutations in Jagged1, a Notch1 receptor are responsible for Alagille Syndrome.

Lentiginosis refers to groups of diseases marked by the presence of pigmented spots on the skin. These conditions are most commonly associated with multiple tumors and changes in hormone producing glands. The cause of these diseases is unknown, but researchers suggest there may be a level of inheritance involved in their development. Meaning to say that some of these diseases may "run in the family" and be passed down form generation to generation. Primary pigmented nodular adrenocortical disease (PPNAD) is a pituitary-independent, primary adrenal form of hypercortisolism characterized by; Resistance to suppression by the drug dexamethasone The body is unable to secrete cortisol in a normal rhythm Distinct microscopic changes of both adrenal glands PPNAD can be associated with tumors (myxomas) of the skin, heart, breast, tumors (swannomas) of the nerve sheaths, pigmented spots (nevi and lentigines) of the skin, growth hormone (GH) producing tumors of the pituitary gland, and tumors of the testicles, ovaries, and thyroid gland. In the presence of these associations the condition is referred to as the Carney Complex. Presently there are no tests for screening of PPNAD and the Carney Complex. In addition, it is unknown how these conditions are genetically transferred from generation to generation. This study proposes to use standard methods of clinical testing for endocrine and nonendocrine diseases and genetic testing in order to; Define the genetic basis for PPNAD and/or the Carney Complex. Determine the molecular changes associated with the development of the tumors. Identify carriers of the disease. Determine the prognosis for carriers and affected individuals. Provide sufficient data for genetic counseling of families with PPNAD and/or Carney Complex.<TAB>...

We seek to investigate whether hospitals in England and Wales vary in their rate of mortality following admission for heart attack or unstable angina, the extent of such variation, whether discharge diagnosis affects the extent of variation, and whether such variation has changed over time. Furthermore, we will investigate what individual- or hospital-level factors explain variation in mortality between hospitals.

The study is a survey to answer the specific question, "What is the prevalence of metabolic syndrome in maintenance hemodialysis patients?" Metabolic syndrome is a cluster of conditions that increase an individual's risk for developing cardiovascular disease and diabetes.

The AIMM Young study is a collaboration between Children's National Medical Center (CNMC) and colleges/universities nationwide--currently including Howard University (HU), East Carolina University (ECU), and University of Massachusetts, Amherst (U Mass). This study obtains a variety of baseline measures (such as serum biomarkers related to metabolic syndrome, anthropometrics, muscle strength, and fitness testing) along with genetic information from healthy college-age (18-35 years) young adults in efforts to identify phenotype-genotype associations that may predispose individuals to developing metabolic syndrome, type 2 diabetes, and/or related diseases such as obesity. We hypothesized that certain genetic variations will be protective against metabolic syndrome, while others will show a strong correlation with specific components of metabolic syndrome disease. We expect that the study of "pre-symptomatic," young individuals will facilitate the identification of genetic risk loci for metabolic syndrome and type 2 diabetes. Younger populations typically have less confounding variables, and this facilitates normalizing of metabolic syndrome features and environment/lifestyle. Additionally, young subjects can provide more robust longitudinal data, and be recruited into subsequent interventions to reverse the trend towards metabolic syndrome, rather than the more difficult task of reversing type 2 diabetes in older populations. The data collected will be stratified according to gender, age, ethnicity, genotype, and other phenotypic measures to determine how these factors influence disease risk.

The purpose of this study is to define the reliability and accuracy of Near Infrared Spectroscopy (NIRS) in the detection of intra-compartmental tissue perfusion in injured and noninjured extremities over time. The investigators hypothesize that this technology, combined with vital signs, intracompartmental pressures and clinical examinations, will be useful in diagnosing acute compartment syndrome (ACS), monitoring patients at risk for ACS, and evaluating the adequacy of fasciotomy in patients treated for ACS.

Survival for one of the most complex forms of congenital heart disease, hypoplastic left heart syndrome (HLHS), has improved dramatically. However, little is known about family stress, coping and outcomes following the diagnosis of HLHS. It is expected that families face emotional, social and financial stressors. Health care professionals have a unique opportunity to positively influence how families interpret and adapt to these stressors. The specific aims of the study are to describe perceived stress, and coping skills utilized, in parents of children with HLHS and their impact on family outcomes measured as well-being, adaptation and caregiver/family quality of life, and to describe changes in stress, coping, and adaptation and differences in perceptions of mothers versus fathers of children with HLHS over the first 14 months of life. The Resiliency Model of Family Adjustment and Adaptation (McCubbin, Thompson, & McCubbin, 1996) is the theoretical framework that guides this research. Hypotheses: Family perception of stress, and coping skills utilized, will have an impact on family outcomes measured as well-being, adaptation, and caregiver/family quality of life. Variables influencing perception of stress and variables influencing family coping will be significant predictors of family adaptation outcomes. Perceptions of stress, coping skills utilized, and family adaptation outcomes will improve during the first 14 months of life with an infant with HLHS. Mothers and fathers will report different perceptions of stress, coping skills utilized, and family adaptation outcomes during the first 14 months of life with an infant with HLHS.

The purpose of this study is to determine if cytokines, inflammatory mediators, are increased in spinal fluid and blood, correlate with disease activity, and could serve as biomarkers or therapeutic targets in children with opsoclonus-myoclonus syndrome (OMS), an autoimmune complication of the tumor neuroblastoma.
