We localize the sources of brain activity of children with epilepsy based on electroencephalograph (EEG) recordings acquired during a visual discrimination working memory task. For the numerical solution of the inverse problem, with the aid of age-specific MRI scans processed from a publicly available database, we use and compare three regularization numerical methods, namely the standardized low resolution brain electromagnetic tomography (sLORETA), the weighted minimum norm estimation (wMNE) and the dynamic statistical parametric mapping (dSPM). We show that all three methods provide the same spatio-temporal patterns of differences between the groups of epileptic and control children.

Methods: Mothers of the prenatal-exposed children (n = 20) were diagnosed with cancer and received chemotherapeutic treatment during pregnancy. We recruited healthy controls (n = 20) who were matched on a 1:1 ratio regarding prematurity, age and sex.

Purpose: The aim of this study was to investigate prenatal and postnatal risk factors for spontaneous intestinal perforation (SIP) in preterm infants.
Material And Methods: Matched case-control study of 62 preterm infants (matching based on gender, gestational age and birth weight) who developed a SIP over a period of 20 years in a single NICU. Univariate and multivariate logistic regression analysis were performed.
