Active clinical trials for "Syndrome"

Our team recently described a new medical condition called HELPS (Hemi-Laryngo-Pharyngeal-Spasm) syndrome(1). HELPS syndrome is a condition caused by a blood vessel pinching the nerve rootlets of the Vagus nerve (Xth cranial nerve). It is similar to the well recognized hemifacial spasm syndrome but the nerve involved is the Vagus instead of the Facial nerve. As a result, the symptoms are episodic throat contractions and cough. The throat contractions become stronger and more frequent over the years and can lead to a terrifying inability to breath. Patients may end up intubated in the Emergency Department or with a tracheostomy because of inability to breath during a severe episode. Some but not all of our patients can tell which side of their throat (left or right) contracts during a choking episode. In between these choking episodes, patients feel normal. A surgical cure for these patients is Microvascular Decompression of the Xth nerve.

To evaluate and compare the NoL index variations after a painful physiotherapy exercise in patients with upper limb CRPS, before and after a stellate ganglion block.

This study aims to identify new morphological and quantitative magnetic imaging parameters of pituitary gland and sellar region in overweight and obese patient at baseline and after 3 years, dividing patients in 3 groups (weight loss through diet and lifestyle changes, weight loss through bariatric surgery, no weight loss)

The purpose of this study is to evaluate the correlation between quality of life (QoL) and hemoglobin in patients affected by myelodysplastic syndrome and to compare the MDS (MyeloDisplastic Syndrome) patient's self-assessed QoL according to physician's evaluation

Carpal tunnel syndrome is caused by compression of the median nerve at the wrist. The hypothesis is that ultrasound imaging can be used to visualize nerve compression in carpal tunnel patients during hand activity, and normal subjects will not demonstrate any nerve compression.

The purpose of the trial is to evaluate the completeness of struts coverage and vessel wall response (strut malapposition, neoin-timal formation) to the bio-active-stent (BAS) versus ever-olimus-eluting stent (EES) implanted for the treatment of the culprit lesion in acute coronary syndrome.

This study aims to compare the alternative current and the direct current signal changes of photoplethysmography between both feet during one side lumbar sympathetic block. The hypothesis is that signal changes occur earlier than other indices to decide whether it is successful following lumbar sympathetic block on only one-side.

This study will explore conditions caused by the absence of certain genes on chromosome 11. These conditions include WAGR syndrome, which is characterized by a kidney tumor called Wilm s tumor, aniridia (absence of the iris of the eye), genital and urinary abnormalities, mental retardation, and possibly other symptoms. This study will examine how the genes on chromosome 11 affect people and whether the absence of specific genes is associated with specific symptoms. Healthy normal volunteers, people with isolated aniridia, and people with WAGR or another chromosome 11 gene deletion may be eligible for this study. Participants must be at least 6 years old. Parents of patients may also participate for genetic studies. Participants undergo some or all of the following procedures, depending on whether they are a child, adult, healthy volunteer or parent of a patient: Medical history and physical examination, eye examination, blood, urine and saliva tests, electrocardiogram (EKG) and electroencephalogram (EEG) X-rays, scans and other tests to measure body composition (fat, muscle and bone development and thickness) and MRI to examine the eyes and the brain and to measure abdominal fat Ultrasound studies of the kidneys, ovaries and uterus (in females) and testes (in males) Meal tests, food diaries and food preference tests Questionnaires about eating and sleep habits, personality and character traits and responses to pain and injury Neuropsychological tests Tests of resting metabolic rate, energy expenditure and glucose (sugar) tolerance Hot and cold sensitivity tests, vibration sensitivity test, cold tolerance test and smell identification test Eye and hearing tests Nerve conduction studies and study of sensory information conduction from peripheral nerves to the spinal cord and brain Computer photography Evaluation by sub-specialists (e.g., endocrinologist, ophthalmologist, physiatrist, neurologist or others) as indicated by the patient s medical history and test results

The antiphospholipid-antibody syndrome (APLA), which includes lupus anticoagulant, anticardiolipin, and anti-beta-2-glycoproteinI antibodies, is a thrombophilic disorder associated with arterial thrombosis, venous thrombosis or both. Patients diagnosed with APLA have a higher risk of recurrent thrombosis than do patients without known antibodies. Currently, warfarin is considered the anticoagulant of choice for prophylactic antithrombotic treatment for APLA patients after their first episode of thrombosis. In some patients with APLA who are treated with warfarin, the INR values determined on plasma are unreliable due to an influence of the APLA on the INR. In these individuals, alternative monitoring methods, such as factor II activity, chromogenic factor X activity or prothrombin-proconvertin time should be used to assess adequate anticoagulation. These tests are expensive and not widely available to some clinicians. Point-of-care (POC) instruments, on the other hand, are readily accessible to clinicians. Previous research has shown that INR values from 3 older point-of-care (POC) instruments are unreliable in 1/3 of APLA patients (CoaguChekTM, ProTimeTM, INRatioTM). However, there are now newer versions of these POC instruments available (CoaguChek XSTM, an investigational ProTime device, and a newer INRatioTM device) and it is unknown if these newer POC instruments are reliable in patients with APLA. The purpose of this study is to determine whether newer POC instruments are reliable in patients with APLA.

This study aims to understand the impact of living with Klinefelter syndrome (KS) and the factors that contribute to adaptation in adolescents and adults. Individuals with KS may have variable symptoms, including hypogonadism, gynecomastia, learning disabilities, and delay and underdevelopment of secondary sexual characteristics. Perhaps the most challenging symptom of KS is infertility, which seems to be a universal symptom. It is not fully understood how males with KS conceptualize their condition, cope with their diagnosis, and adapt to living with this condition. In this study, Lazarus and Folkman s Transactional Model of Stress and Coping provides a framework for examining coping and adaptation in males with KS. A cross-sectional research design using a quantitative survey will be utilized to examine the relationships among appraisals (illness perceptions and perceived stigma), time elapsed since learning of diagnosis, coping, and adaptation. Adolescents and adults with KS will be recruited from national KS support networks via website postings, email listservs, and printed newsletter postings. Adolescents will also be recruited from a private practice. Participants will have the option to complete an online or paper version of the survey. The main outcome variable is adaptation to living with a KS diagnosis.
