title: [Latex sensitization prevalence through prick test in patients with genitourinary malformations and more than 3 surgeries].
abstract: Latex allergy is a public health issue. It presents elevated prevalence in known risk groups, especially in those patients with spine bifida condition, urinal malformation and for those with orthopedic problems - multiple surgeries. Health Services in Mexico do not have the enough studies about prevalence and risk associated to latex allergy.
  
  
  
  Determine latex sensitization prevalence through PRICK test in patients with genitourinary malformations and more than 3 surgeries in UMAE pediatric CMNO unit, considering too related factors.
  
  
  
  An analytical and descriptive cross-sectional study was performed, which included men and women from 1 to 16 years with genitourinary malformations and more than three surgeries performed. A survey to know the risk factors associated and skin puncture test was performed with latex extract, with positive and negative control. Serum levels of total IgE and eosinophils were measured in peripheral blood.
  
  
  
  The study exposed prevalence of 30.72%. Related to associated factors as follows: atopy (p=0.047), previous antecedent reaction to latex products (p=0.003) specific for balloons (p=0.000) and gloves (p=0.002). There was not association related to amount of surgeries and surgical interventions on early age, either for high levels of total serum IgE.
  
  
  
  Prevalence to latex sensitization is high in risk groups. Especially in those with atopy thereby is important for health personal to identify these patients in order to implement on time the preventive primary/secondary measures. With these actions potential mortal risks like anaphylaxis will be avoided. This will decrease sanitary costs and mortality.
