Active clinical trials for "Syndrome"

The purpose of this study is to find out if there is a connection between a higher level of peptide alpha defensin in blood serum with the metabolic profile of adolescents aged 13-17.

Post-operative paediatric cerebellar mutism syndrome (pCMS) is a well-recognised complication of resective surgery for brain tumours of the cerebellum and fourth ventricle in children. Occurring in around 25% of infratentorial craniotomies, it is characterised by a delayed onset of mutism and emotional lability, and may comprise motoric and cognitive cerebellar deficits. Transient mutism gives way to prolonged, and often incomplete, recovery. Neuroimaging studies are beginning to reveal anatomical and functional aberrancies in the brain of children with pCMS. The cerebellar efferent pathways are likely to be implicated as a neuroanatomical substrate in the development of pCMS, as shown by a handful of diffusion tractography studies to date. However, the pathophysiology of this condition still remains unclear. Hypoperfusion of supratentorial cortical and subcortical structures may mediate the speech and behavioural deficits seen in pCMS, and is a candidate for a causal pathophysiological mechanism. This study aims to prospectively image children with pCMS using advanced MRI techniques including diffusion tractography and arterial spin labelling, and to correlate this with clinical descriptions of the syndrome. All children referred to Great Ormond Street Hospital for Children with a posterior fossa brain tumour will be imaged pre-operatively, post-operatively and at delayed follow-up. In tandem with this, clinical assessments will be made of children post-operatively to ascertain which patients develop pCMS. In addition, anonymised advanced MRI data on healthy controls will be used as a comparator group.

The study purpose is to evaluate the morphological, functional and electrophysiological characteristics of the right ventricle before and after ajmaline in patients diagnosed with Brugada syndrome as well as to correlate CMR findings and substrate size.

To evaluate long-term intraocular lens (IOL) decentration and tilt in eyes with pseudoexfoliation syndrome (PES) following cataract surgery using Visante anterior segment OCT and iTrace Visual Function Analyzer.

Mortality rates in children with pediatric acute respiratory distress syndrome (PARDS) are higher in Asia compared to other regions. In adults with acute respiratory distress syndrome, the only therapy that improves mortality rates is a lung protective ventilation strategy. The pediatric ventilation recommendations by the Pediatric Acute Lung Injury Consensus Conference (PALICC) are extrapolated from evidence in adults, including ventilation with low tidal volume, low peak/plateau pressures and high end expiratory pressure. A recent retrospective study of ventilation practices in Asia including Singapore showed that a majority of patients with PARDS were being ventilated with high tidal volume, high peak pressure and low end expiratory pressure, not in compliance with PALICC recommendations. We postulate that currently used ventilation strategies could have contributed to the high PARDS mortality rates in Asia. We aim to determine if implementing a ventilation bundle comprising PALICC recommendations lowers PARDS and pediatric intensive care unit (PICU) mortality rates.

Sjogren's Syndrome is a chronic autoimmune disease characterized by sicca (dryness) symptoms of the mouth and eyes. This autoimmune disease is less commonly studied and there are no licensed treatments to treat the underlying cause of disease and current management is based on clinical experience and/or small clinical studies. This study is based on DSP methodology, a multinational, cross-sectional, multi-sponsor survey of robust real-world data. DSP methodology collects quantitative market research data. The pSS DSP will survey a sample of approximately 230 to 325 rheumatologists and their prospectively consulting pSS subjects in France, Germany, Italy, Spain and the US. The data will be collected via physician interviews, physician workload questionnaires, detailed patient record forms (PRFs) to be completed by physicians, and a self-completion questionnaire by pSS subjects. The data collected using this method includes subjective and objective evidence, clinical information about individual patients, their disease and their treatment. This DSP will follow three key phases: preparatory phase, data collection phase and data processing/analysis phase.

The purpose of this study is to assess benign joint hypermobility syndrome (BJHS) in children with a history of wheezing or asthma. BJHS is a common syndrome of joint and connective tissue laxity without any other rheumatologic disease. This assessment will be performed by using either method below depending upon if the child has a history of wheezing or severe asthma: Determine the correlation, if there is an increased rate of BJHS in children with a history of wheezing as well as if there is an increased history of wheezing in children with BJHS; or Determine asthma control, lung function and asthma exacerbations (a flare up or acute worsening of symptoms) in children with BJHS compared to children with asthma without BJHS, to assess if it BJHS is associated more with children with severe asthma.

The purpose of this study is to learn about patient, caregiver and healthcare worker perspectives on educating patients with newly-diagnosed Nephrotic Syndrome. All patients enrolled in the Contact Registry with Nephrotic Syndrome will be invited via email to participate in this study.

Primary: The primary objective of this study under the original protocol was to provide neuromuscular specialists and neurologists access to amifampridine phosphate therapy for their patients with LEMS, CMS or downbeat nystagmus until the product became commercially available. Secondary: The secondary objective of this study under the original protocol was to provide additional long-term safety data on amifampridine phosphate in patients. Primary The primary objective of this study after its fifth amendment was to provide access to amifampridine phosphate therapy to pediatric patients with LEMS, and pediatric and adult patients with CMS until the product became commercially available for these indications or development of the product for the indication was terminated. Secondary: The secondary objective of this study after its fifth amendment was to assess the long-term safety of amifampridine phosphate in pediatric patients with LEMS, and pediatric and adult patients with CMS.

The Acute Respiratory Distress Syndrome (ARDS) is one of common clinical critically diseases. In the United States, the incidence of ARDS reaches 31%, which is one of the main causes of death in patients. There is no unified treatment process for ARDS currently and the treatment measures are not yet standardized, so the standardization of ARDS treatment processes is needed to reduce mortality in patients. Following the evidence-based medicine principles and six-step treatment standards of ARDS, this study uses the method of multi-center randomized controlled clinical trials to evaluate the standardized treatment process of ARDS, which provides the basis for the standardized treatment of ARDS.
