Nasal Provocation Tests
Application of allergens to the nasal mucosa. Interpretation includes observation of nasal symptoms, rhinoscopy, and rhinomanometry. Nasal provocation tests are used in the diagnosis of nasal hypersensitivity, including RHINITIS, ALLERGIC, SEASONAL.
Nasal Lavage Fluid
Fluid obtained by irrigation or washout of the nasal cavity and NASAL MUCOSA. The resulting fluid is used in cytologic and immunologic assays of the nasal mucosa such as with the NASAL PROVOCATION TEST in the diagnosis of nasal hypersensitivity.
A subcategory of CHRONIC OBSTRUCTIVE PULMONARY DISEASE. The disease is characterized by hypersecretion of mucus accompanied by a chronic (more than 3 months in 2 consecutive years) productive cough. Infectious agents are a major cause of chronic bronchitis.
Predictive Value Of Tests
In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.
Basophil Degranulation Test
An in vitro test used in the diagnosis of allergies including drug hypersensitivity. The allergen is added to the patient's white blood cells and the subsequent histamine release is measured.
Hypersensitivity pneumonitis (HP) is a rarely encountered inflammatory interstitial lung disease caused by various antigens. Studies in the literature report contradictory rates about its prevalence....
OBJECTIVE: To investigate the clinical indications of asthma control test (ACT). METHODS: A total of 120 asthmatic patients with a diagnosis in line with the American Thoracic Society criteria and tre...
History and admission findings: A 34-year-old female stonemason was referred for expert opinion. The question at issue was, whether she suffered from vibration-induced white finger disease. She was ex...
Abstract Background: Although leukotriene D4 (LTD4) was a potent bronchoconstrictor, little is known about airway responsiveness to LTD4 in asthmatics with different inflammation phenotypes. Objective...
Pigeon circoviruses (PiCV) had been identified worldwide and are responsible for immune suppression and a variety of diseases collectively referred to as young pigeon disease syndrome. Samples from ra...
Chronic cough is defined by its persistence beyond 8 weeks. Many conditions can explain the existence of a bronchial inflammation. In the management of chronic cough, the search for bronch...
The sphincter of Oddi is a circular band of muscle which controls the flow of pancreatic juices and bile into the small intestine. Abnormal function of the Sphincter of Oddi, known as Sphi...
Venous Pressure Measurement of the Great Saphenous Vein Using Controlled Compression Ultrasound in Healthy Persons and Patients With Chronic Venous Disease as a New Non Invasive Method for Investigation of the Pathophysiology in Primary Varicose Veins
Part I: Proof of concept trial to achieve normal venous pressure values under different provocation maneuvers in healthy persons Part II: Non invasive measurement of venous...
This study aims to compare the efficacy of nasal provocation test with Lysine-Acetylsalicylate in patients with history of NSAIDs hypersensitivity between mucocutaneous symptoms and respir...
This study is meant to compare two routine diagnostic approaches in patients with bronchial asthma. Patients are challenged with methacholine in order to measure their bronchial response....
