Active clinical trials for "Syndrome"

Although for many years the Brugada syndrome has been labelled as a purely electrical disease in the structurally normal heart, the evolution of imaging techniques has enabled the discovery of subtle morphofunctional alterations in some of the Brugada syndrome patients. We will use new echocardiographic techniques to assess cardiac function in these patients and new parameters will be evaluated for their prognostic value as risk stratificators.

The purpose of this study was to investigate the serum concentrations, physical and psychological well-being characteristics in patients having chronic musculoskeletal pain with metabolic syndrome, and to compare patients without metabolic syndrome.

The primary aim of the study is to investigate whether optical coherence tomography (OCT) may be a useful tool for investigating the in-vivo histology of ocular structures in patients with tear film pathology. In epiphora the investigators will image the proximal lacrimal system. In dry eye syndrome the investigators will image the lacrimal gland and also the buccal mucosa. The secondary aim of the study is to investigate the appearance of the normal cornea and conjunctiva under OCT imaging.

This is a follow-up cohort study of 8 years old children born preterm at Seoul National University Children's Hospital in Korea from 2008-2009. The children will visit outpatient clinics for examinations regarding growth, obesity and other risk factors related to metabolic syndrome. The purpose of this study is to compare growth and risk factors of metabolic syndrome among children born preterm and children born healthy term at school age

The purpose of this study is to evaluate the potential diagnostic and prognosis value of circulating microRNAs compared with cTnI for suspected ACS patients at the emergency department (ED) and intensive care unit (ICU).

Medical researchers of National Heart Centre Singapore will carry out a state-of-the-art study that examines the possibility of changing patients' own cells into multi-functional and potent stem cells called iPS cells. These iPS cells can subsequently give rise to functional cardiac cells (myocytes) and other cardiovascular cells which might give further clues into the manifestation of the structural heart disease. This study involves blood sample collection for pre-screening and skin biopsies to establish skin cell culture.

The purpose of this study is to develop and applicate two new genetic deafness gene diagnostic kit for Waardenburg syndrome and large vestibular aquduct syndrome.

COPD and sleep apnea dyspnea syndrome represent two of the most common chronic lung diseases. It is reported that the prevalence of COPD with sleep apnea dyspnea syndrome is also very high. COPD and sleep apnea may have pathological or genetics interactions so that patients having both disorders tend to have worse outcomes than either condition alone. Data reflecting the prevalence, disease course and outcome of overlap syndrome is very limited in China. Therefore, the aim of the study is to describe the prevalence, treatment and outcome in Chinese patients and exploring the underlying interaction mechanism.

The purpose of this study is to collect information and bone marrow, blood, saliva, cheek cells and skin to be used in the laboratory to assist the sponsor in identifying a new way of treating MDS.

The research project aims to try to answer the many questions raised by the identification of new early repolarization syndrome. The questions are varied with both taking optimal clinical management of patients, the frequency and significance of this anomaly in the population on the electrophysiological and molecular basis responsible for this electrocardiographic abnormality. To try to answer these many questions, the approach will be twofold: clinical and genetic. Establishment of a clinical database containing information of patients who have been identified as carriers of the anomaly based on the initial clinical presentation in order to determine their prognoses. Physiological approach will be based on a molecular approach to identify genetic abnormalities may be involved in this syndrome. 200 asymptomatic patients and an unlimited number of patients who presented syncope or aborted sudden death will be included. A blood sample (15 ml) will be performed at inclusion.
