Patterns of communication about AIDS among Hispanic and Anglo adolescents.

This study examined exposure to AIDS information from mass media and interpersonal communication among a nonprobability sample of Hispanic and Anglo lower middle-class adolescents. Subjects were drawn predominantly from community health clinics, word of mouth recruiting, public service announcements, churches, schools, and health fairs in San Diego County. Both Hispanic (n = 220) and Anglo (n = 159) youths reported substantial exposure to information about AIDS from both mass media and interpersonal communication. Hispanics watched more general television than Anglos, but had less exposure to newspapers and interpersonal communication with friends. Communication among friends was most consistently related to sociodemographic variables, with older, higher status persons and girls communicating to the greatest extent. Boys reported the greatest communication with family. Anglo youths had greater exposure to information about AIDS and condoms regardless of the medium of communication, while Hispanic adolescents had greater exposure to information on risks of IV drug use. Of the three main types of mass media, print and radio provided the most exposure to AIDS information. It is important for preventive medicine practitioners to exploit these differences in communication patterns when planning preventive intervention strategies that target specific adolescent populations.

Telepathology: a diagnostic tool for the millennium?

Many developments in science have their origins in science fiction and telepathology is no exception. The concept was first illustrated in 1924 in the magazine 'Radio News'. It was not until 1980, however, that the first working telepathology system was demonstrated. Although the system was shown to work, it required special hardware, dedicated software and special microwave transmission links to be installed. Little interest was shown worldwide because of the very high cost and the inability of many people to replicate such a system. Ten years later, the personal computer (PC) was able to provide more than adequate performance at low cost for both image display quality and speed, and the development of video technology had resulted in high quality images being produced by television cameras that were now easily affordable. Microscopes were also relatively cheaper. Thus, by 1993 or 1994, all the hardware necessary to produce a telepathology system was available at reasonable cost. Telepathology can now be used for remote primary diagnosis, remote referral to a specialist pathologist, remote teaching, remote presentation of post-mortem or microscopic findings, quality assurance image circulation and feedback, and consensus diagnosis for pathological review in clinical trials. There are two residual problems. The first concerns the speed of data transmission, commonly referred to as the bandwidth. The second is that the software provided by most of the manufacturers and suppliers of these systems is not entirely suitable to the task and the systems are not interoperable. It is clear that the approach of the manufacturers is at present unlikely to produce telepathology systems which pathologists feel comfortable in using. A somewhat different approach is illustrated by the accompanying article in this issue from the Berlin group, where a relatively simple Java-based applet and the Internet are used to allow single or multiple users to view slides on a robotic microscope. This could form the basis for a truly useful system, but still needs modification for some applications.

Experimental procedures and statistical results for evaluation of exposure to a radiofrequency electromagnetic field with complex analogue modulation.

The paper illustrates an experimental set-up used to monitor over long periods the peak and average power associated with a complex analogue modulated signal. The procedure was applied to a standard PAL television transmission. The measurement was carried out from a remote location, and a complete tele-measuring system was designed, configured and tested. Following the application of the measuring system to some real cases, interesting statistical results illustrating long-period exposure values were reported.

Characteristics of wastes from electric and electronic equipment in Greece: results of a field survey.

The lifespan of electric and electronic equipment is becoming shorter and the amount of related waste is increasing. This study aimed to contribute to the knowledge about qualitative and quantitative characteristics of such wastes in Greece. Specifically, results are presented from a field survey, which took place in the city of Thessaloniki, Greece, during the year 2002. The survey was conducted with suitable questionnaires in department stores and in households of various municipalities. Household appliances were grouped as follows: (A) large (refrigerator, freezer, washing machine, clothes dryer, electric cooker, microwave oven, electric heater), (B) small (vacuum cleaner, electric iron, hair dryer), (C) information technology and telecommunication equipment (PC, laptop, printer, phone) and (D) consumer equipment (radio, TV, video, DVD, console). The analysis indicated that the lifespan of all new goods is gradually reducing (apart from refrigerators, for which the lifespan was surprisingly found to be increasing) and provided linearized functions for predicting the lifespan, according to the year of manufacture, for certain large appliances.

Effects of acute exposure to ultrahigh radiofrequency radiation on three antenna engineers.

Three men were accidentally exposed to high levels of ultrahigh frequency radiofrequency radiation (785 MHz mean frequency) while working on a television mast. They experienced an immediate sensation of intense heating of the parts of the body in the electromagnetic field followed by a variety of symptoms and signs which included pain, headache, numbness, and parasthesiae, malaise, diarrhoea, and skin erythema. The most notable problem was that of acute then chronic headache involving the part of the head which was most exposed.

[Ways to increase the information value of ultrasonic studies in the diagnosis of intraocular tumors].

The paper discusses possibilities to increase information value of ultrasound investigations in diagnostics of intraocular tumors by means of a developed informative system of acoustic diagnostics ISAD-2 on the basis of a microcomputer "Electronika-60" (OVK-2) and broad-band ultrasound piezo-transformer with a working frequency from 2 to 20 mHz. Examination of 50 patients (50 eyes) with suspected intraocular tumors resulted in enucleation of the eye ball in 45 patients (45 eyes). Comparison of ultrasound and histomorphologic investigations revealed a correlative connection between the structure of intraocular tumor and the texture of their radio-frequency echograms as well as with relative frequency dependence of ultrasound attenuation in it. The possibility of in vivo detection of the tumorous process influence on the eye ball sclera and extrabulbar invasion of the tumor is determined. Different data bases are created which consider questionnaire data of examined patients, ecologic situation, the factor of a genetic risk, results of ultrasound and histomorphologic investigations, etc. Amalgamation of data bases makes it possible to classify intraocular tumors by different informative signs and to identify them depending on their microstructure.

Radio medical advice--the Danish experience.

From 1980 to 1993, the Danish Radio Medical Advice Service (RMAS) had 1136 contacts from overseas Danish merchant ships and 213 contacts from Danish territorial waters. The diagnoses were almost always of acute conditions. The distribution of the diagnoses in the overseas contacts were; diseases in the digestive and genitourinary system 30%, traumatic lesions 23%, infectious diseases 14% and diseases in the cardiovascular and respiratory system 9%. The only trend over the years was a significant (P = 0.01) decrease in psychiatric diagnosis. Evacuation from the ship was recommended in 53% and medicine was prescribed in 61% of the contacts. The medicine was antibiotics in 40% and analgesics in 29% of the contacts. Intravenous infusion was evaluated as relevant in 5% of the cases and this procedure will be included in the new education of officers on the ships. In the contacts from Danish territorial waters, where many ships are recreational yachts, evacuation was recommended in 79% and medicine was prescribed in 28% of the contacts. This was probably due to the short distance to the nearest harbour and the variation in medical equipment and knowledge. The medical speciality for doctors participating in RMAS should be general surgery or orthopaedic surgery but access to advice from all other medical specialities should be available. Experience as a naval medical officer would be beneficial. The education of the officers on the ships should be more comprehensive including e.g. intravenous infusion. Communication should be by telephone and television would be an advantage.

The relationship between religious activities and cigarette smoking in older adults.

BACKGROUND: The objective of this study was to examine the relationship between religious activities and cigarette smoking in community-dwelling older adults. METHODS: Cigarette smoking and religious activities were assessed in a probability sample of 3968 persons age 65 years or older participating in the Duke Populations for Epidemiologic Studies of the Elderly (EPESE) survey. Participants were asked if they currently smoked, if they ever smoked, and how many cigarettes per day they smoked. Attendance at religious services, participation in private religious activities (prayer or Bible study), and use of religious media (religious TV or radio) were also assessed. Data were available for Waves I-III of the survey (1986, 1989, and 1992). Analyses were controlled for age, race, sex, education, alcohol use, physical health, and in the longitudinal analyses, smoking status at prior waves. RESULTS: Cross-sectional analyses revealed that participants who frequently attended religious services were significantly less likely to smoke cigarettes at all three waves. Likewise, elders frequently involved in private religious activity were less likely to smoke (Waves II and III). Total number of pack-years smoked was also inversely related to both attendance at religious services and private religious activities. Watching religious TV or listening to religious radio, on the other hand, was not related to smoking at Waves I and II nor to total pack-years smoked, but was positively related to current smoking at Wave III. Among those who smoked, number of cigarettes smoked was inversely related to frequency of attendance at religious services (Wave I), private religious activities (Wave III), and religious TV/radio (Waves II and III). Retrospective and prospective analyses revealed that religiously active persons were less likely to ever start smoking, not more likely to quit smoking. CONCLUSIONS: Religiously active persons are less likely to smoke cigarettes, and if they do smoke, smoke fewer cigarettes. Given the association between smoking and disease, and the widespread prevalence of both smoking and religious activity, this finding has implications for public health.
