Patients' ability to react before complex partial seizures.

OBJECTIVE: The purpose of the study described here was to investigate the pathophysiology of patients' ability to react during the conscious (aura) phase of complex partial seizures (CPS) originating from the temporal lobe. METHODS: We reviewed video recordings of CPS experienced by 130 adult patients who had undergone epilepsy surgery for intractable medial temporal lobe epilepsy. All patients were instructed to push the alarm button when they felt an aura. We defined the preictal reactivity as the ability to push the alarm button before the complex partial (unconscious) phase of seizures. RESULTS: Seventy-seven patients (59%) pushed the alarm button before seizures. Patients with preictal reactivity were significantly younger, more often had lateralized EEG seizure patterns, and had a better postoperative outcome. Patients who did not push the alarm button had secondarily generalized seizures more often. CONCLUSIONS: Ability to react before CPS is associated with a circumscribed region involved at seizure onset and spread, and with a seizure-free postoperative outcome.

AX.25 amateur packet radio as a possible emergency network.

In modern society more and more medical applications need a reliable data transfer. In emergency situations, such transfer may not be available because parts of the communications infrastructure may be affected. An alternative way could be the use of the amateur radio packet network, which offers almost global coverage. We analyzed its use as an emergency data transfer support, including transport of real-time medical data.

Social and personal factors in marijuana use and intentions to use drugs among inner city minority youth.

Limited information is available about the etiology of illicit drug use among minority youth. This study examined predictors of marijuana use and intentions to use marijuana, cocaine/crack, and other drugs for African-American and Hispanic seventh graders (N = 757). Self-reports of marijuana use and intentions to use drugs were collected along with data concerning background, social environmental, and individual characteristics hypothesized to be related to drug use. Results indicated that social influences, including adults, friends, and the most admired person's marijuana use, predicted marijuana use. Individual characteristics, such as a lack of knowledge about the prevalence and negative social consequences of marijuana use, positive attitudes toward marijuana use, and inadequate social, communication, and refusal skills increased suspectability to marijuana use. Lack of self-efficacy was related to intentions to use cocaine and other drugs. Implications of these findings are discussed with respect to the development of effective prevention programs.
