The "innocent" cough or sneeze: a harbinger of serious latex allergy in children during bladder stimulation and urodynamic testing.

Abstract

Latex hypersensitivity is a well documented phenomenon most commonly reported in children with spina bifida during surgical and other procedures involving exposure to latex. IgE-mediated immediate hypersensitivity to the protein or polypeptide components of latex may be severe and manifest as generalized anaphylaxis or cardiovascular collapse. Of 17 children with spina bifida undergoing transurethral electrical bladder stimulation we identified 5 with latex allergy 3 to 9 years old. All 5 patients were noted to manifest sneezing or a cough several minutes before the development of a generalized hypersensitivity reaction, which in several patients progressed to bronchospasm. Subsequent investigations have shown that the inciting agent was the rectal pressure balloon made from a latex finger cot. Recognition of the earliest manifestations of latex hypersensitivity is an important clinical tool in the prevention of severe allergic reactions.
