Convulsions in neonatal period and infancy with rare etiology (neurogenetic disease)

: Authors summarized the etiology of convulsions in neonatal period and infancy (hypoxia, intracranial hemorrhage, infections of central nervous system, metabolic background, chromosomal abnormalities, brain developmental abnormalities, benign neonatal convulsions, benign neonatal familial convulsions, drug withdrawal, inborn error of metabolism). They suggest screening examinations after convulsion, summarized the basic principle of tandem examination and review a proposal at suspicion of inborn error of enzyme defects (aminoacidemias, defects of fatty acid oxidation, organic acidemias). They present case history of two patients suffered in extraordinary inborn error of enzyme defect (SCO2 gene mutation, propionic acidemia). Diagnosis originated in Helm P61 Hospital (settlement Madarasz Hospital) with a Hungarian and international cooperation.
