It has been suggested that the atopic population has decreased risk of cancer. This investigation examined the cumulative prevalence of atopy in a population with neoplastic disease and compared this with the prevalence of atopy in an age-matched control group and with published estimates of atopy in the general peopulation. Seventy-four patients with neoplastic disease and 86 patients without ...

BACKGROUND Polyethylene glycols (PEGs) or macrogols are polyether compounds and are widely used as additives in pharmaceuticals, cosmetics, and food. CASE REPORT We report on a Caucasian patient experiencing recurrent severe allergic reactions to several drugs. An extensive diagnostic workup including skin prick tests, intradermal tests (IDT) and a double-blind oral challenge was performed to...

OBJECTIVES A previous study showed that bee venom (BV) could cause anaphylaxis or other hypersensitivity reactions. Although hypersensitivity reactions due to sweet bee venom (SBV) have been reported, SBV has been reported to be associated with significantly reduced sensitization compared to BV. Although no systemic immediate hypersensitive response accompanied by abnormal vital signs has been ...

Liposomal amphotericin-B (AmBisome) is now becoming first choice for the treatment of visceral leishmaniasis (kala-azar) patients due to high efficacy and less toxicity. The reported incidence of hypersensitivity reactions to liposomal amphotericin-B (AmBisome), especially during therapy, is very rare. We report two patients with kala-azar: one developed breathing difficulties and hypotension f...

OBJECTIVE To assess how commonly clinically significant biphasic anaphylactic reactions occur after apparently successful treatment of an anaphylactic reaction. Cases were analysed to determine whether there were any markers that would allow early identification of patients who would subsequently develop a biphasic response. METHOD Retrospective review of case notes of 34 patients admitted fo...

Immediate responses of hypersensitivity to skin testing with purified derivative of tuberculin (PPD) were observed in 2.3 percent of 3,248 patients seen in an allergy clinic, and the relationship to delayed responses was questioned. Immediate cutaneous reactions to testing with PPD appeared in all age groups and occurred in nonatopic patients but were more common in atopic patients (p less than...

BACKGROUND Radix Scutellariae, a few papers reported its pharmacology activities including alleviate small intestines smooth muscles spasm, sedation, antihypertensive effect. However, the inhibition of its different organic extracts on immediate hypersensitivity has not bee researched. MATERIALS AND METHODS To investigate the anti-immediate hypersensitivity of three extracts including ethanol...
