title: [Prediction of etiology based on the clinical type of convulsion in the neonatal period].
abstract: OBJECTIVE
  To determine whether the seizure clinical type is predictive of etiology.
  
  
  METHODS
  This is a prospective study from 9 neonatal and pediatric intensive care units. Neonatal seizures were defined clinically as described by Volpe. The seizures etiology was defined by positive clinical date, cranial sonogram and laboratory investigation routinely obtained in all neonates with seizures. Correlation between seizures type and etiologies was determined by Odds ration (OR).
  
  
  RESULTS
  During one year 89 neonates develop neonatal seizures and the etiologies were determined. The mains seizures types were: subtle (n = 59; 66.3%), tonic (n = 27; 30.4%), clonic (n = 20; 22.4%), myoclonic (n = 4; 4.5%). The most frequent etiologies determined were: asphyxia (n = 60; 67.4%), hypocalcemia (n = 19; 21.3%), hypoglicemia (n = 14; 15.7%), peri-intraventricular hemorrhage (n = 13; 14%). The OR estimate that clonic seizures (OR 5.65 - 1.34 < OR < 23.61%) is predictive to peri-intraventricular hemorrhage.
  
  
  CONCLUSIONS
  The OR estimate high risk to periventricular hemorrhage when the seizure is the clonic type. When the seizure is subtle type the risk is low to this etiology.
