Hypersensitivity to anticonvulsant drugs have been reported many times. But anticonvulsant hypersensitivity syndrome (AHS) is a potentially fatal drug reaction with cutaneous and systemic reaction to the arene oxide-producing anticonvulsants, phenytoin, carbamazepine, and Phenobarbital sodium. The hall-mark features of this syndrome are: Fever, rash and lymphadenopathy. The epoxide hydrolase en...

BACKGROUND The oral provocation test (OPT) is the current gold standard to diagnose aspirin hypersensitivity syndrome although it is time-consuming and contains some systemic risks. Other reliable methods with lower side effects and shorter test duration are being investigated. OBJECTIVE The purpose of this study was to evaluate the efficacy of the nasal provocation test (NPT) and the basophi...

The effect of ubenimex on graft-versus-host reaction and delayed cutaneous hypersensitivity in mice was studied. Ubenimex enhanced the graft-versus-host reaction in a dose range from 0.005 to 0.5 mg/kg. Ubenimex inhibited the aging-caused decrease of delayed cutaneous hypersensitivity to oxazolone and the efficacy was greater with older mice. Ubenimex also inhibited mitomycin C and L1210-caused...

Summary The authors present 2 case reports of selective cefazolin hypersensitivity: a 49 year-old woman with a history of two perioperative reactions (urticaria and severe anaphylaxis) after the use of rocuronium, propophol and cefazolin; a 36 year-old pregnant woman who developed facial erythema, lips angioedema and hypotension immediately after administration of ropivacain, sufentanil, cefazo...

It is well established that viral infections may precipitate or worsen attacks of bronchial asthma. Furthermore, in symptomatic atopic subjects, the local accumulation of basophils and the production of a basophil chemotactic factor have been reported. We have investigated the effect of cell-free supernates from viral stimulated cultures of human mononuclear cells on the in vitro migration of h...

The performance of naked neck and normal chicken was evaluated with respect to growth, carcass, immune, biochemical and stress parameters under winter and summer seasons to assess the suitability of naked neck birds under high temperatures in the global scenario of climate change. The growth performance was significantly (p≤0.05) higher in naked neck chicken in the summer season. The dressing p...

This study was conducted to determine the frequency of sensitization to Aspergillus antigens in 27 patients with perennial rhinitis. Immediate cutaneous reactivity was observed in 7 (26%) patients. In 3 of these 7 patients, hypersensitivity was restricted to Aspergillus antigens alone. One patient had an isolated late cutaneous reaction. Hypersensitivity was observed most commonly with A. flavu...

Two homologous lightly coupled dinitrophenyl conjugates of poly-L-lysine of differing average molecular sizes were compared with regard to their abilities to elicit in guinea pigs specific delayed hypersensitivity skin reactions, passive cutaneous anaphylaxis, and active Arthus reactions. Equal concentrations by weight (but not equimolar concentrations) of the two conjugates elicited equally in...
