Filter by:Obstructive sleep apnea/hypopnea syndrome (OSAHS) is a highly prevalent disorder with multiple comorbidities. OSAHS is characterized by repetitive episodes of airflow reduction (hypopnoea) or cessation (apnoea) due to upper airway collapse during sleep. Its major risk factor is obesity. However, its pathogenesis is complex and multifactorial. Reduced upper airway muscle tonus and/or unstable neuromuscular output seem to be involved in this collapsus. A normal vitamin D status is necessary for normal muscle function and neuromuscular output. As obesity is associated with a high rate of hypovitaminosis D, it appears of interest to evaluate the effect of vitamin D supplementation on OSAHS patients with vitamin D deficiency.
The literature does not discuss if the fast oral appliance titration (30 days period) in Obstructive Sleep Apnea Syndrome (OSAS) treatment, may improve subjects quality of life in such brief period. Temporomandibular dysfunction-related (TMD) is one of the most important side effects observed in OSAS treatment with oral appliance. Since the effectiveness of mandibular exercises in the control of TMD pain has already been verified, it may play a fundamental role in the support of the fast oral appliance titration.
Purpose: 1. To demonstrate better symptoms control (pain, urinary urgency and frequency) with sacral neuromodulation (SNM) in patients with interstitial cystitis /painful bladder syndrome (IC/PBS) using a stimulation frequency of 40 hertz (experimental) compared to a frequency of 14 hertz (standard). 2. The evaluate the efficacy of the two frequency settings on the other associated conditions that often coexist in patients with IC/PBS, such as female sexual dysfunction (FSD), bowel dysfunction, high tone pelvic floor dysfunction (HTPFD, painful spasm of the pelvic floor muscles), Vulvodynia (pain at the opening of the vagina).
This study is being performed to develop assays to determine the impact of the therapy patients receive for treatment of AML or MDS and to determine if these tests can identify those patients who are at a greater risk for having their disease relapse.
Establishing a Data Base for Aplastic Anemia and Other Marrow Failure Syndrome
Irritable bowel syndrome (IBS) is a common disorder affecting up to 20% of the general population. Despite the prevalence of the disorder, it remains poorly understood. This is reflected in a symptom based diagnostic scheme, the lack of a suitable biological marker and inadequate treatment options. Current knowledge suggests the disorder is as a result of a dysregulated brain-gut axis, a complex construct describing the bidirectional communication systems underpinning normal gastrointestinal functioning. The investigators hypothesize here that the disruption of this brain-gut axis is facilitated by an increased degradation of tryptophan along the kynurenine pathway. This metabolic abnormality has the potential to impact on both GI and CNS signaling through its effects on serotonergic signaling and the impact of metabolites like kynurenic acid and quinolinic acid on cognitive processes respectively. Previous data from our laboratory indicated increased tryptophan degradation in IBS patients and suggested the metabolites produced as putative biological markers of the condition. In this study the investigators aim to reconcile cognitive impairment in IBS with GI and CNS symptom severity and kynurenine pathway metabolites. The investigators will establish these baseline measures in IBS compared to control subjects. A battery of cognitive assessments will be carried out using a computerized testing system. Standardized rating scales will be used to assess GI and CNS symptom severity. GC-MS/MS, a recently acquired technology platform in our laboratory, will be used to quantify plasma quinolinic acid levels.
The present study is designed to determine the mutational status of markers (TET2 and PLCb2, cytogenetic aberrations) together with methylation status of the above genes using bone marrow and matched buccal cell samples from MDS patients who necessitate to start a treatment (i.e. EPO, Lenalidomide, Azacytidine). All patients included in the study will be followed for at least 2 years.
Carpal tunnel syndrome (CTS) is the most common compressive focal mononeuropathy seen in clinical practice. Patients commonly experience a constellation of symptom complex brought on by compression of the median nerve as it traverse through the carpal tunnel. When compression of the nerve occurs, ischemia and mechanical disruption of nerve function may result. Pathological analysis shows a constellation of nerve injuries. Until now, no satisfactory conservative treatment method. Local steroid injections or oral steroids may result in initial relief, but relapses are frequent and have much side effects, which preclude their routine use for CTS. Full time wrist splints are claimed effective, but compromise hand function and daily activities. There are reasonable studies showing relief of pain with acupuncture on diverse pain conditions. However the therapeutic efficacy of acupuncture in CTS was less convincing in the past. Until recent decade, some case reports and few prospective studies reported the therapeutic effect of acupuncture in CTS. Other study also reported that low-level laser and microamperes transcutaneous electrical nerve stimulation (TENS) are effective in improvement of clinical outcome of patients with CTS. Another report suggested that TENS should be considered for the treatment of painful diabetic peripheral neuropathy. Therefore, the investigators perform this study to evaluate the effect of Aculife Magnetic Wave Therapist (a battery operated device with a probe electrode which contains magnetic elements that transform the oscillating current into an electromagnetic wave to stimulate the acupuncture points, simulate the effect of electroacupuncture ) on CTS and compared with that of Transcutaneous Electrical Nerve Stimulation(TENS). After at least 4 weeks treatment ( at least 16 treatment sessions) the therapeutic effects will be evaluated by comparison of symptom severity score, electrophysiological study, sonographic morphology study or magnetic resonance imaging study, before and after treatment, and between the different groups.
Susac Syndrome is a rare disease and the establishment of the diagnosis is often difficult. The aim of this investigation is to identify relevant biomarkers and to elucidate the pathogenesis of Susac syndrome
The primary objective of the EASY-CHINA Registry is to describe the clinical epidemiology of Chinese patients with NSTE-ACS, to evaluate their current anticoagulation management in China, and the resources used for it.
