Active clinical trials for "Syndrome"

The use of ActiveCare+S.F.T 3rd generation (an Intermittent Pneumatic Compression Device) will improve quality of life in patients suffering from Post Thrombotic Syndrome compared to compression stockings which is the current gold standard of care.

Acoustic Pharyngometry (AP) is a method of measurement of Transversal Sectional Areas (TSA) and Volumes of oral cavity and pharynx, based on acoustic waves. The aim of this study is to describe changes on oropharynx dimensions caused by CPAP (Continuous Positive Air Pressure) in patients with severe Obstructive Sleep Apnea Syndrome when compared with patients with Primary Snore, using AP. The exam will be made during the use of CPAP, at various pressures. The investigators also intend to determine if pressure determined by Polysomnography in OSAS patients cause some type of different change in AP graphic.

Clinically Characterized by the presence of chronic widespread pan and tenderness, Fibromyalgia (FM) is one of the most common "functional" syndromes. FM is currently conceived of as representing a prototype of central pain, i.e. a condition in which sensitization of the central nervous system results in a overall increase in the processing of painful stimuli, as well as an impairment of pain inhibition. This condition is responsible for significant a social and economic burden and is estimated to affect up to 5% of all women. The 1990 American College of Rheumatology (ACR) classification criteria for FM are the current standard for studying FM, and require the presence of widespread pain lasting over 3 months, as well as documentation of tenderness in at least 11 of 18 pre-defined "tender points. Multiple additional symptoms, which are not part of the classification criteria, include among others sleep disturbances, mood disturbances, cognitive dysfunction, vulvodynia, dysmenorrhea, sexual dysfunction and weight fluctuations. In addition, FM is well known to overlap both clinically and epidemiologically with an ever increasing number of other "functional" disorders, including irritable bowel syndrome (IBS), Temporomandibular joint disorder (TMJD), functional dyspepsia etc. In addition to the central symptom of pain, FM patients frequently complain of non- specific symptoms which are potentially autonomically - mediated. Thus, palpitations, fatigue and inability to stand for long periods of time are all common complaints. About 80-90 percent of FM patients have one or more symptoms associated with autonomic dysfunction. The most common of them is presyncope (62.5%), followed by syncope (12.5%), palpitations on standing (12.5%) and dizziness (12.5%) (14). Some of these symptoms overlap with those of the postural tachycardia syndrome (POTS). POTS is a common dysautonomia, characterized by remarkable increased heart rate during the assumption of the upright posture (>30 bpm). According to our experience, FM is found, at least, in 15% of POTS patients. But, no data exists about the incidence of POTS in patients with FM.The role of the autonomic nervous system (ANS) in initiating and maintaining the syndrome of FM has been studies (and debated) over the last decade. The ANS is an extremely complex system, regulating involuntary body functions, including heart rate, intestinal motility, urination, and sexual activity, among many other variables. Notably, the vagus has an inhibitory effect on pain. Deterioration in the vagal control is "associated" with increased pain sensation. Previous studies have indicated that FM patients may have an increase in sympathetic control over the cardiovascular system with a reciprocal decrease in parasympathetic control. High sympathetic tone is usually associated with a lower threshold to pain. But, the contribution of the ANS to the pathogenesis of FM syndrome remains unclear. Evidently, the ANS interacts with other components of the CNS in the pathogenesis of FM, including pain processing centers in the thalamus and amygdala, as well as with the hypothalamic-pituitary-adrenal (HPA) axis.

Background: Potential negative effects of pacing in the RV-apex are well documented However, study results comparing septal / RVOT-pacing versus RV-apical pacing controversial. The optimal pacing mode in SSS (DDDR versus AAIR) is unclear, as the DDD (R) mode with an AV delay ≤ 220 ms should be the preferred pacing mode, according to the DANPACE trial [DANPACE, ESC 2010, Stockholm]. Aim: - to evaluate chronic effects of proven right ventricular septal compared to minimized right ventricular septal pacing in patients with SSS Inclusion criterion: -Pacemaker indication according to current guidelines: sick sinus syndrome (SSS) Exclusion criteria: Life expectancy < 2 years Age <18 years Noncompliance with regard to participation in the study Pregnancy AV block ° 2 and higher Permanent atrial fibrillation Heart failure NYHA III and IV, reduced LV-EF <40% ICD indication Acute coronary syndrome. PCI or CABG <3 months Heart transplant Placement of septal RV electrode is not possible Study design: Prospective, monocentric, randomized, double-blinded Run-in phase: for weeks AAI [R]-DDD [R] Randomization: two groups A) septal right ventricular chamber pacing: mode DDD [R] versus B) Reduction of unnecessary ventricular pacing: AAI [R]-DDD [R]. FU: 6 and 12-months Primary endpoints: -LV ejection fraction and end-systolic LV volume after 12 months. Secondary endpoints: -LV end-diastolic volume, TAPSE, parameters of dyssynchrony (SPWMD, LV-PEP, IVMD), AF-burden, % ventricular pacing, CPX: peak oxygen consumption (peak VO2), VO2 AT, VO2/HR, VE/VCO2 slope; QoL scores (SF-36) after 12 months. Statistics/sample size estimation: In order to detect a difference in LVEF of 5% and for LV-ESV of 5 mL between the 2 groups after 12 months: 90% power/alpha 5%: 84 patients per group 80% power/alpha 5%: 63 patients per group 10% for compensation of drop-outs / patients lost of follow-up. Two-sided 5% type 1 error Analysis intention-to-treat and based on the finally programmed pacing mode. Material PG: market released dual chamber pacemakers with the ability to pace AAI(R) -DDD(R) pacing leads: market-released standard active electrodes RV electrode: septal verified under multi-level screening (RAO/LAO) and ECG (LBBB narrow <150 ms / inferior axis)

Introduction The portable monitoring system (PMS) recording of cardiopulmonary parameters (level III of ASDA) has been validated in subjects with high probability of Obstructive Sleep Apnea (OSA) without comorbidities. However, there is not any study evaluating this system when OSA is associated with morbid obesity, so the validation of PMS will be very useful in order to properly work-up this highly risk population. Objective: To evaluate the accuracy of level III type of PMS - Stardust™" (STD), on patients with level II and III of obesity and high clinical suspicion of OSA. Methods:Participants with BMI > 35 kg/m2 and with suspicion of OSA will consecutively be selected from an Outpatients Sleep Clinic of UNIFESP. They will be randomized for the following order of recordings: 1) STD at home for 1 night 2) STD in the sleep lab simultaneous to PSG. AHI will be taken for subsequent analysis:a) AHI PSG b) AHI STD -lab and c) AHI STD- home.

The purpose of this study is to examine the efficacy of a capsular tension ring (CTR) in preventing anterior capsule shrinkage after cataract surgery in exfoliation syndrome (XFS) with no zonular weakness. The eyes with XFS undergo phacoemulsification and aspiration (PEA) with an intraocular lens (IOL) implantation. All operations are performed by a single surgeon. No eyes with either ectopia lentis or phacodonesis are included. There are three groups; CTR is not used in group A, CTR is simply implanted in group B, and CTR is implanted and closed by tying both eyelets in group C. The areas of continuous curvilinear capsulorhexis (CCC) are calculated, and both the time-course change and the comparison among the 3 groups are tested.

Study aims to: (1) evaluate the role of morphological and physiological characteristics of the pelvic floor, pain-related psychological and -psychophysical variables in prediction of the success of myofascial physical therapy (MPT) for the treatment of painful bladder syndrome Patients with clinical symptoms of PBS will undergo physical examination, sensory testing in the genital area, perineal ultrasound examination for the evaluation of the length of the levator muscles before MPT and following 10 consecutive sessions of MPT. Improvement in clinical symptoms will be assessed and evaluated for correlations with psychophysical examinations.

This observational study will based on the Register of Information and Knowledge About Swedish Heart Intensive Care Admissions (RIKS-HIA) and the Swedish Coronary Angiography and Angioplasty Registry (SCAAR) which since 2009 are merged into The Swedish Web-system for Enhancement and Development of Evidence-based care in Heart disease Evaluated According to Recommended Therapies (SWEDEHEART). The aim of this study is to investigate the impact of different antithrombotic treatment options (treatment duration, type of treatment and combination of treatments) in Acute Coronary Syndrome (ACS) patients on outcomes such as recurrent ischemic events and mortality.

Our study is observational, we are observing data from routine measurements during IVF/ICSI. Our study does not assess IVF/ICSI as an intervention, we are evaluating the role of FSI and preovulatory count which are calculated by observing routine measurements during the IVF/ICSI procedure. 300 women with polycystic ovarian syndrome (PCOS) who are decided to be treated with ICSI. will be subjected to full history taking and clinical examination. On the second day of menstruation serum FSH, LH, Prolactin and Oestradiol will be assessed and the antral follicular count (AFC) will be assessed using a vaginal ultrasound scan. AFC will be defined as the number of follicles measuring 3-10mm. All patients will have standard pituitary down-regulation followed by follicle stimulating hormone (FSH) stimulation until the day of Human chorionic gonadotrophin (HCG) administration. On the day of HCG administration, ovarian ultrasound scan will be performed using a transvaginal probe and the Preovulatory follicle count (PC) will be assessed, (PFC) is defined as number of follicles measuring≥16mm. Follicular output rate (FORT) will be calculated as: (FSI =PFC*10000/AFC*Total dose of FSH). FORT correlation to pregnancy will be compared to that of the preovulatory count number

The purpose of this study is to test a specific nerve stimulation protocol as therapeutic option in patients diagnosed with CRPS (complex regional pain syndrome) of the upper extremity.
