[Latex allergy in children with spina bifida]

Latex allergy is a frequent happening in children with spina bifida or congenital urologic abnormalities. These patients have multiples exposures to derivatives of latex as part of the management increasing the risk of allergic reactions. We present three children who developed general anaphylactic reaction during urodynamic exploration with a rectal latex catheter. All patients showed positive skin test and positive latex specific IgE test (RAST). A prospective survey of 17 patients with spina bifida at the time of cystometry showed positive RAST levels in 7 (41%). Recommendations for prophylaxis are included, suggesting the avoidance of latex products in children with spina bifida since birth.
