RESUMO
La epilepsia se caracteriza por la aparición de diversos tipos de crisis que se acompañan de alteraciones específicas en el EEG en forma de brotes paroxísticos. Durante los periodos intercríticos el registro puede ser normal. En ocasiones, pueden evidenciarse alteraciones en respuesta a mecanismos de activación específicos. El diagnóstico de las crisis no convulsivas puede ser difícil de establecer. En algunos tipos de epilepsia, especialmente en la del lóbulo temporal, se han descrito conductas agresivas durante las crisis. Exponemos el caso de un homicida, varón de 20 años, sin antecedentes de conductas conflictivas, que presentó una conducta violenta explosiva que junto con su especial vivencia de los hechos llevó a la sospecha de la existencia de organicidad. El EEG evidenció una alteración compatible con epilepsia que podría explicar la aparición de la conducta agresiva (AU)
Epilepsy is characterized by the onset of various types of crisis which are accompanied by specific alterations in EEG as paroxysmal outbreaks. Registration may be normal during intercritical periods. Sometimes, alterations in response to specific activation mechanisms can be evidenced. Diagnosis of the non-convulsive crises can be difficult to establish. In some types of epilepsy, especially in that of the temporal lobe, aggressive behaviors during the crises have been described. We present the case of a 20 year-old male, a murderer with no previous deviant behavior, who displayed an explosive violent behavior. His particular experience of the events led to the suspicion of the existence of organicism. EEG showed an alteration compatible with epilepsy that might explain the onset of the aggressive conduct (AU)

BACKGROUND AND OBJECTIVE: Because of high fatality rate associated with acute infection by hepatitis A virus (HAV) in chronic hepatitis C patients, it is of interest to know the prevalence of immunization against HAV in these patients. PATIENTS AND METHOD: Immunoglobulin G (IgG) IgG HAV antibodies (IgG anti-HAV) were determined in 313 hepatitis C virus antibodies (anti-HCV) positive patients and in 313 anti-HCV negative subjects (control group). Several epidemiological factors were recorded (age, sex, rural vs urban precedence, tattoos, parenteral drugs use, alcohol consumption and surgery). RESULTS: The prevalence of IgG anti-HAV was identical in both groups: 81.2%. However, in those younger than 41 years, this prevalence was greater in those anti-HCV positive than in the control group. Parenteral drugs use and tattoos were more frequent in the first group. The presence of IgG anti-HAV was associated with age and the rural origin in both groups. CONCLUSIONS: The prevalence of IgG anti-HAV increases with age, and is more frequent in individuals with rural origin. It was also greater in young anti-HCV positive patients, when compared with controls of the same age. This finding can be due to the poor standards of hygiene probably associated with some practices more common in this population, such as parenteral drugs use, tattoos and others.
