The recent literature describing zinc action on gastrointestinal epithelial tight junctions and epithelial barrier function is described. Zinc enhancement of gastrointestinal epithelial barrier function may figure prominently in its potential therapeutic action in several gastrointestinal diseases.展开更多

A diffuse maculopapular rash developed after the administration of piperacillin. It resolved with discontinuation of the drug and the patient was switched to aztreonam and a very similar rash developed subsequently. In a review of the literature, there are no documented cases of a patient with an allergy to both aztreonam and piperacillin/tazobactam despite in vivo cross-reactivity. Unfortunately, there are no standardized allergy tests for aztreonam or piperacillin. This case, however, does offer the possibility that aztreonam may not always be the right alternative to persons with beta-lactam antibiotic allergies.展开更多
