Burns associated with the use of microwave ovens.

This article reviews published reports of conventional and radiation burns associated with the use of microwave ovens. Conventional food burns can result from the ingestion of microwave heated food because consumers may overlook the differential temperature gradients within foods and between the food and the container. There are reports of accidental radiation injury associated with the use of microwave ovens, but they are difficult to evaluate because these reports lack definitive clinical data and verification of the actual radiation exposures. Only one study has provided useful insight into the clinical features of microwave radiation burns compared to conventional burns.

A comparison of two treatment interventions aimed at lowering anxiety levels and alcohol consumption amongst alcohol abusers.

This study compared the differential efficacy of anxiety management and relaxation training - with respect to their impact on anxiety levels and alcohol consumption amongst people attending an Alcohol Treatment Unit. It was hypothesised that anxiety management would have a greater effect on the outcome measures than would relaxation training and that the effect on alcohol consumption would be moderated by changes in the clients' perceptions of their ability to control their drinking. The two treatment groups were found to significantly reduce self-reported anxiety with the anxiety management group being more effective than relaxation training. They had no impact on alcohol consumption.

Contrast sensitivity versus static visual field testing during experimental elevation of intraocular pressure.

Contrast sensitivity testing has been recommended as a more sensitive indicator of early visual loss than visual field testing. Using gravity inversion to induce an intraocular pressure rise, we performed contrast sensitivity testing on each eye of 10 normal subjects in the upright and inverted positions. Contrast sensitivity results were not altered in the head-down position, even though in 5 of the 10 subjects (7 of 20 eyes), visual field alterations on static perimetry were elicited during inversion. In both of these evaluations, the subject's results in the upright position served as the control, freeing us from reliance upon age-matched populations. We conclude that precise measurement of static thresholds with automated perimetry is more sensitive than routine contrast sensitivity testing in detecting visual dysfunction related to transient acute elevations of intraocular pressure.

Exploring the use and non-use of marijuana as reasoned actions: an application of Fishbein and Ajzen's methodology.

Fishbein and Ajzen's methodology can predict behaviour on the basis of questionnaire measures of attitudes toward the specific act and the subjective norms with respect to that behaviour which the individual experiences. In the present study this methodology was used to differentiate between the non-users, experimenters, occasional users and regular users of marijuana in a student population. It is argued that Fishbein's approach enables each of these groups' behaviour to be seen as a reasoned action; also discriminant analysis shows how particular evaluative beliefs and social norms interact to predict and explain the individual's drug-user status.

Patterns of drug use among methadone maintenance patients in Los Angeles county.

Any evaluation of the effectiveness of methadone maintenance programmes in rehabilitating heroin addicts is inherently complex and subject to varied interpretations, both scientific and philosophical. From a scientific perspective, it is necessary to accumulate sufficient factual data to validate any hypothetical conclusions. A retrospective survey of drug-use patterns among the methadone maintenance population of Los Angeles County was undertaken in an effort to provide some such information. Over 5,000 urine samples from 730 paitients were analysed for eleven drugs over a two-month period in 1975. Over 23 per cent of these samples were found positive for a drug other than methadone and 80 per cent of these positives were attributed to illicitly used drugs. The opiates (codeine and morphine) comprised almost 74 per cent of the drugs found while barbiturates and amphetamine and/or methamphetamine contributed 16 per cent and 10 per cent to the total, respectively.
