Allergic conjunctivitis (AC),a disorder of the conjunctiva in which an allergic component plays a key role, affects approximately 15-25% of the adult and pediatric population 1-8. Estimates in the literature indicate that the seasonal allergic conjunctivitis (SAC) occurs most frequently, followed by atopic keratoconjunctivitis (AKC), vernal keratoconjunctivitis (VKC), perennial allergic conjunc...

Background A previous study by our group (JACI 2003;112:45-50) showed a significant allergic gastrointestinal inflammation in birch pollen allergic patients with gastrointestinal symptoms during the birch pollen season. The pathophysiological mechanisms of this type of allergic reaction are still poorly studied. However it is not yet explored if all birch pollen patients have signs of gastroint...

The Vaccine Adverse Event Reporting System has received reports of allergic reactions following immunization with egg-free recombinant influenza vaccine, among patients with a self-reported egg allergy or previous allergic reaction to inactivated influenza vaccine. These results suggest that allergic reactions following influenza vaccination are not necessarily related to egg proteins.

orthodontic treatment of individuals with metal hypersensitivity is a matter of concern for the orthodontist. orthodontic appliances contain metals like nickel, cobalt and chromium etc. metals may cause allergic reactions and are known as allergens. reaction to these metals is due to biodegradation of metals in the oral cavity. this may lead to the formation of corrosion products and their expo...

Kounis syndrome is an acute coronary syndrome concurrently occurs with allergic or hypersensitivity reactions. In patient with this syndrome, inflammatory mediators released due to an allergic reaction implicate to induce coronary artery spasm and atheromatous plaque rupture. We describe a patient with coronary artery disease who developed acute perioperative myocardial infarction leading to ca...

Background Allergic reactions during perioperative period may vary in terms of incidence, type of reaction and severity. Reactions ranging from mild skin disorders up to cardiac arrest might be observed. The lack of post-event investigation and a failure of interaction, due to a poor communication, between anesthesiologist and allergist represent risks for a re-exposure to the allergen. The exi...

Penicillin is the drug that most often leads to allergic reactions and anaphylaxis. The incidence of adverse events triggered by penicillins is believed to be between 1% and 10%. Up to one-tenth of these episodes are life-threatening, with the most serious reactions occurring in patients with no history of allergy. The case of a 5 year, 3 month-old female who had a severe allergic reaction to a...

Natural vitamin E is suggested to have an antioxidant function. However, the synthetic form of vitamin E, DL-tocopherol, which has been widely used in topical ointments, may cause allergic contact dermatitis. Here, we report a case of allergic contact dermatitis with erythema multiforme-like eruption caused by a topical ointment. Patch testing indicated a positive allergic reaction to an anti-i...

We are reporting a rare case of a delayed hypersensitivity reaction caused by hyaluronidase allergy following a lumbar transforaminal epidural block. Using an intradermal skin test, we have provided evidence that the systemic allergic reaction resulted from hypersensitivity to hyaluronidase. To our knowledge, this is a rare case of a delayed hypersensitivity reaction to epidural hyaluronidase, ...

OBJECTIVE This study investigated allergic fungal rhinosinusitis cases, and aimed to compare the detection of fungi in sinus aspirate by culture and by polymerase chain reaction assay, and to relate the presence of fungi in the nasal sinuses to the type of fungal allergen causing disease. METHODS Sixty-eight cases of allergic fungal rhinosinusitis underwent fungal culture and polymerase chain...
