Comparative performance for immediate hypersensitivity skin testing using two skin prick test devices.

TLDR
The two methods are similar with respect to determining the immediate hypersensitivity, but the Multi-Test is better accepted by children.
Abstract
Fifty-five patients were skin-tested by Multi-Test (M) and needle prick test (NPT) to compare the reproducibility of the methods. We used 6 allergenic extracts: Dermatophagoides pteronyssinus, Dermatophagoides farinae, dog epithelium, cat pelt, American cockroach and mixed molds. A glycerosaline and a positive control (histamine 1 mg/ml) were performed in both methods. Statistically significant differences in histamine and Dermatophagoides farinae wheal reactions between the two methods (M > NPT) were found, with no differences with the other allergenic extracts. We concluded that the two methods are similar with respect to determining the immediate hypersensitivity, but the Multi-Test is better accepted by children.

Current best practice for the health surveillance of enzyme workers in the soap and detergent industry.

TL;DR: This study defines current best practice for the health surveillance of workers who are potentially exposed to enzymes in the manufacture of enzymatic detergent products and recommends that health surveillance is performed 6-monthly for the first 2 years and annually thereafter.

International conference on allergic rhinitis in childhood

TL;DR: The term "rhinopathy" has been recently adapted to fit the allergic form where the pathophysiological background does not implicate the classical inflammatory infectious form, but the concept of rhinopathy has not displaced the much more widely and commonly used term, "Rhinitis."

The Lancet Weight Determines Wheal Diameter in Response to Skin Prick Testing with Histamine.

TL;DR: It is concluded that the applied weight of the lancet during the SPT-procedure is an important factor and additional research is needed to improve the specificity and sensitivity of the procedure.

Bimodal skin reactivity to histamine in atopic children in Singapore: influence of specific sensitizations.

TL;DR: Children with polysensitization and mould sensitization were more likely to show a large significant histamine response, whereas children with passive smoke exposure, showed a diminished skin reactivity to histamine.

Comparison of the Multi-Test II and ComforTen allergy skin test devices.

TL;DR: Multi-Test II had notably lower CV, greater wheal size, and higher sensitivity but similar specificity to ComforTen, and had superior performance at both 3- and 5-mm wheal cutoffs.
