Until some time ago, the tuberculin skin test was the only available screening test for the diagnosis of tubercular infection. Now the new interferon-? release assay QuantiFERON-TB Gold shows promise of greater accuracy in the detection of Mycobacterium tuberculosis-infected subjects. The aim of our study was to evaluate the use of QuantiFERONTB Gold in children and to verify its agreement with...

Objective: To identify the responsible allergens in patients with allergic rhinitis using skin prick test and further to help create the chart showing allergen distribution in Duzce region of Turkey. Methods: This retrospective case series included 192 patients diagnosed with allergic rhinitis between June 2014 and June 2016 in the private office of the author. The diagnosis of allergic rhiniti...

brandenburg, stanley, and anatum, showed no reduction in viable count compared with MacConkey's medium. The growth of salmonellae was somewhat slower than on ordinary MacConkey agar but most produced colonies of 1 mm diameter at 22 hours and only five required incubation for 36 hours. Six of the 41 Salmonella species tested failed to grow (typhi, paratyphi A and C, cholerasuis, gallinarum and p...

The immune response induced by vaccination with Bacille Calmette-Guérin (BCG) is not fully understood, and the interpretation of the tuberculin skin test (TST) is still under debate. This thesis was based on questions raised while implementing protective measures for healthcare workers and others at risk of exposure to tuberculosis (TB) in Sweden, a country where the prevalence of TB is low. Th...

Skin prick testing is an essential test procedure to confirm sensitization in IgE-mediated allergic disease in subjects with rhinoconjunctivitis, asthma, urticaria, anapylaxis, atopic eczema and food and drug allergy. This manuscript reviews the available evidence including Medline and Embase searches, abstracts of international allergy meetings and position papers from the world allergy litera...

The niacin skin test reflects a flush and oedema owing to the production of prostaglandin D2 from arachidonic acid. A diminished response may indicate abnormalities in the phospholipid metabolism, which has been shown in schizophrenia. There is evidence that dyslexia might also involve phospholipid abnormalities, therefore we examined the skin response in 51 dyslexics and 45 controls. Four conc...

Pathergy phenomenon is defined as a state of altered tissue reactivity that occurs in response to minor trauma. Pathergy test (PT) is an easy to perform skin test to look for the pathergy phenomenon. This test is used as a criterion in most diagnostic criteria for Behcet’s disease e.g., Dilsen criteria, Japan revised criteria, International criteria, Iran traditional format criteria, and the Cl...

Background: Crude latex extracts are commonly used in skin prick tests (SPT) for the diagnosis of natural rubber latex (NRL) allergy. Nevertheless, variations in protein and allergen composition between latex extracts from different manufacturers can hamper a correct diagnosis. Objectives: To analyze the heterogeneity of proteins and allergens in latex extracts from 7 different manufacturers an...
