Microassay and Allergy Skin Prick Test Correlation Study

Allergy Pollen

The purpose of this study is to evaluate the potential correlation of the results of allergen-specific skin prick tests (SPT) to that of allergen-specific microarray determination (microassay test). Subjects who meet enrollment criteria, after signing an IRB approved consent form, will perform a minor finger prick blood draw and blot to be mailed off for microassay analysis. Specific statistical analysis will be done to assess all potential correlations between SPT and microassay. This study design should enable assessment of the level of correlation between SPT results and microassay results for specified allergens within a cohort of subjects with allergic rhinitis.

Skin Barrier Abnormalities and Oxidative Stress Response

Atopic DermatitisFood Allergy

This is a prospective, single-site controlled observational study designed to comprehensively determine whether children and adults with atopic dermatitis (AD) and food allergy (FA) have skin abnormalities which distinguish them from children with AD without FA, and non-atopic (NA) controls.

Evaluation of the Role of Follicular Sensitivity Index in the Prediction of Pregnancy in Women Undergoing...

SubfertilityAssisted Reproduction

1000 women with infertility who are already 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 (Human menopausal gonadotrophin (HMG) 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 sensitivity index (FSI) will be calculated as: (FSI =PFC*10000/AFC*Total dose of FSH)

Prognostic Significance of the Baroreflex Sensitivity Changes After Acute Ischemic Stroke

Cerebrovascular AccidentBaroreflexes1 more

After acute stroke, baroreflex sensitivity (BRS) is impaired. This impaired acute stage BRS has been reported to be predictive of worsen outcome years after stroke in general. However, it is not very clear if the impaired acute stroke BRS would actually persist months after the acute stage. It is also not clear that such change, if any, would correlate with the functional outcome or prognosis after stroke. The trial is to investigate the longitudinal time course of BRS after ischemic stroke up to the 6th month post stroke and to see if there is any correlation of the changes in BRS with the functional outcome parameters using NIHSS and mRS scores throughout this period.

Incidence and Nature of Heparin-induced Skin Lesions in Medical Patients

Allergy

An increased number of patients with heparin-induced skin lesions is reported in the literature. Heparin-induced skin lesions may result from either occlusion of cutaneous vessels in patients suffering from autoimmune HIT or from a type IV allergic reaction (delayed type hypersensitivity (DTH) response). However, the incidence and nature of heparin-induced skin lesions has not been determined in a prospective investigation. To address this open issue is the goal of this ongoing, so far monocenter, clinical investigation.

Heart Rate, Baroreflex Sensitivity and Cardiovascular Morbidity and Mortality in the Population...

Community Based StudyCardiovascular Disease2 more

The aim of the present PPS3 study is (1) to assess the determinants of the regulation of heart rate and blood pressure variations and carotid properties (under different physiologic stimulations) and (2) to evaluate the respective contribution of heart rate, blood pressure variations and carotid properties to cardiovascular morbidity and mortality including sudden death during 10 years at least in healthy considered subjects.

Validation of the Turkish Version of the Pain Sensitivity Questionnaire

Pain

The Pain Sensitivity Questionnaire(PSQ) is a self-rating measure for the assessment of pain sensitivity and has been developed by Dr. R. Ruscheweyh in Germany. It consists of 17 items rated from 0, not at all painful to 10, most severe pain imaginable. The validation of the Turkish version of PSQ is needed, in order to measure pain sensitivity among Turkish people.

Tromsø Birch Rust Allergy Study. Allergy to Birch Rust, a Possible Explanation to Seasonal Airway...

HypersensitivityImmediate1 more

In this project we study if spores from birch rust fungi (Melampsoridium Betulinum = MB) may be the eliciting allergen in patients with seasonal airway allergy during autumn in North Norway. Patients with suspected allergy to MB are compared with non-allergic controls using data about allergic disease and daily allergic symptoms during autumn. Daily spread of MB spores are compared with daily variations in allergic symptoms. Sensitization to MB and MB allergy are tested with skin prick test, specific immunoglobulin E (IgE) in serum, nasal provocation test and basophil activation test (BAT).

The Prevalence of Contact Allergies for Wound Dressings In Patients With Diabetic Foot Ulcers (PAID...

Diabetic FootContact Allergy

Rationale: Foot ulcers among diabetics are common. The presence of a contact allergy limits the healing process. Contact allergies for wound dressings are common among patients with ulcers caused by venous insufficiency but less is known about contact allergies in diabetic patients with ulcers. Objective: To determine the prevalence of contact allergies for wound dressings in patients with diabetic foot ulcers. Study design: A prospective multicenter study. Study population: Patients (n=139) with diabetic foot ulcers caused by type 1 or 2 diabetes mellitus treated at Rijnstate Hospital Arnhem, the Netherlands. Main study parameters/endpoints: The primary study parameter is the presence of contact allergies for wound dressings. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: An allergy test is standard procedure at Rijnstate Hospital, there is no direct technique-related burden or risk for the patient. In addition, wound dressings can be adjusted in patients where a contact allergy is determined which will benefit the prognosis of these patients. The data of this study will give insight in the prevalence of contact allergies for wound dressings in patients with diabetic foot ulcers.
