The authors aimed to evaluate the prevalence of problem behaviors in a representative randomized national sample of youth in the Czech Republic. The Social and Health Assessment (SAHA), a school survey, was administered to a nationwide sample of 4,980 adolescents in three age cohorts (12, 14, and 16 years) in Prague and 12 regional capitals of the Czech Republic. Three antisocial behaviors, i.e. fistfight, damage of public or private property, and shoplifting, were the most frequent in both genders, while carrying a gun or a weapon (blade, knife, gun) to school were also highly prevalent among boys. The levels of alcohol and cigarette use were high, and increased with age. Marijuana, amphetamines and met-amphetamines were the most frequently used illegal drugs in both genders. Risky sexual behaviors, assessed in 16-year-old adolescents, were also common, with only 64.5% of boys and 46.8% of girls reporting condom use and 27.7 of boys and 21.0% of girls reporting that they had 4 or more sexual partners. This study demonstrated a relatively high prevalence of risk behaviors in Czech youth, a finding with major implications for public health and future research.

We examined a group of 77 autistic children (61 boys, 16 girls) of an average age 9.1 ± 5.3 years. The Childhood Autism Rating Scale (CARS), IQ test and 21 channel EEG (including night sleep EEG recording) were applied. It was possible to obtain evaluable EEG records in 63 patients. Missing EEG records were mostly due to noncooperation on the part of the autistic children. There were 28 normal EEGs (44.4%), 11 non-epileptiform abnormal EEGs (17.5%), and 24 abnormal EEGs with epileptiform discharges (38.1%). Using the median test, we compared the psychopathology in these three groups. No significant difference in the total CARS score was found among the groups. In the analysis of CARS items, there was only one significant difference among the groups in the 10th item - Fear or Nervousness (chi2 = 7.963, df = 2, p = 0.019).
