In order to investigate the possible role of molds in respiratory allergy, skin prick tests with the extracts of 19 different fungi were applied to 614 respiratory allergic patients. Indoor mold samples of some of these mold sensitive patients are also presented. Most of the patients (72.6%) had extrinsic asthma while 27.4% having allergic rhinitis. The diagnosis was based on history, clinical examination and skin prick test which was done according to Peppy's method. Aspergillus fumigatus was the most important fungus causing skin test positivity (26.0%). Trichophyton rubrum, Mucor, Penicillium notatum, Aspergillus niger and Alternaria tenius species were also important in decreasing frequencies. A total of 26 species were isolated and Penicillium was the most important one (29.6%). Molds are thought to play an important role as causative agents for allergic rhinitis and asthma.

Behçet's disease is a kind of variable vessel vasculitis (VVV) and inflammatory systematic disease affecting various organs of the body. The cause of the disease is idiopathic but is most commonly genetic in origin. A positive skin prick test (dermatographia), genital sores, eye irritation, skin sores, and at least three episodes of mouth sores in a year confirm the diagnosis.

Background: Penicillin allergy is reported in 5% to 15% of the world population, with 3% to 10% of pregnant women reporting the same. However, more than 90% of these patients can tolerate penicillin after appropriate evaluation. Penicillin is indicated for various issues that arise in pregnancy, and a history of allergy can have negative individual and public health consequences.

Purpose Of Review: There is an increasing awareness among clinicians that industrial and household food processing methods can increase or decrease the allergenicity of foods. Modification to allergen properties through processing can enable dietary liberations. Reduced allergenicity may also allow for lower risk immunotherapy approaches.

Cow's milk allergy (CMA) is the most common food allergy among children. An oral food challenge (OFC) remains a mainstay of the diagnosis of CMA, especially for the non-IgE-mediated type; however, this test can be risky and time-consuming. Hence, there is a need to identify biomarkers.

Atopic dermatitis (AD) is a chronic inflammatory skin disorder influenced by proteins involved in skin barrier maintenance and vitamin D metabolism. Using an intra-patient design, this study compared protein expression in intra-lesional (IL) and peri-lesional (PL) skin biopsies from AD patients and examined associations between protein levels, vitamin D status, and clinical features. Forty-four biopsies from twenty-two AD patients were analyzed using antibody microarrays targeting twelve proteins.
