Study of mortality risk factors for children under age 5 in Abu Dhabi.

We investigated the association of biological, sociocultural and economic risk factors with child mortality in Abu Dhabi from 1 January-31 December 1997. With McNemar chi-squared test, most selected biological risk factors were statistically associated with child mortality, although maternal age older than 40 years and history of fetal death were not positively correlated with neonate, infant or age under 5 mortality. Among sociocultural and economic risk factors, maternal lack of formal education and low monthly income were significantly associated with child death. Consanguinity was significantly associated with under 5 and infant but not neonatal mortality. Gestation <37 weeks was highly associated with mortality among all ages. Strengthening health care programmes and emphasizing the need to identify high risk groups should be priorities.

The development of a telemedicine laboratory as a medical faculty resource.

A telemedicine facility was established for the Faculty of Medicine of the University of Aberdeen and developed as a laboratory to help ensure a scientific approach to the implementation of telemedicine. Once a service application has been positively evaluated and established then it should be funded and delivered outside the laboratory, thus freeing up time and resources for the evaluation of new areas. Since it would appear that the practice of telemedicine is here to stay, it would also seem reasonable to suggest that an introduction to telemedicine should be included in the medical undergraduate curriculum.

International collaboration in the development of postgraduate research training (692).

Research training leading to a higher degree can be difficult for those who live in countries where advanced educational facilities are not yet available, since it may involve translation of a whole family to a foreign country with resultant language, financial and cultural problems. There are special difficulties for females and those of the Moslem faith, who may have been married early and already have a family by the time of initial graduation. There may also be cultural difficulties preventing overseas study for the unmarried female. This paper describes a flexible approach developed by the University of Aberdeen in association with the Ministry of Health in Kuwait. This was an MSc course on the process of continuous quality assurance in medical practice which was based on the concept that research training was the best means of evaluating and measuring quality. The students were finally assessed on the quality of their research dissertation. The course, which was part-time, and thus lasted for 2 years, required them to spend 12 weeks in each of two successive summers in Aberdeen. The subject chosen for each dissertation was related to the work area of the candidate and was studied in the country of origin with the help of periodic visits by the supervisors. The results were surprisingly successful since the students became highly motivated by the problems of their own country and were encouraged by their colleagues at home. The process could have been even more successful if videoconferencing facilities had been available at both the Aberdeen and Kuwait centres. It is concluded that a more flexible approach by western universities would result in an increase in both the quantity and the quality of postgraduate study.

Erythrocyte cholinesterase activity levels in desert farm workers.

In this study we have examined 532 migrant farm workers engaged mainly in the cultivation of vegetable crops, in both greenhouses and openfarms, and an equal number of controls. Erythrocyte acetylcholinesterase activity (AChE) was measured to determine the degree of toxicity due to exposure to organophosphate and carbamate pesticides in the farm workers employed either as foremen (41.5%) or farmers (58.5%). The mean ages of the farm workers and controls were 35.2 +/- 7.4 (mean +/- SD) years and 34.6 +/- 7.1 years. AChE activity of the farm workers and controls was 3.89 +/- 0.64 UI/ml (mean +/- SD) and 4.15 +/- 0.29 UI/ml. The haemoglobin adjusted erythrocyte cholinesterase activity (HAChE) was 29.96 +/- 4.14 (mean +/- SD) for farm workers and 32.10 +/- 2.26 for controls. AChE activity was very highly significantly lower for the foremen (3.76 +/- 0.69) compared to farmers (3.98 +/- 0.59) (Student's t-test = 4.13, p = 0.0001). HAChE was also very highly significantly lower for foremen (29.24 +/- 4.37) compared to farmers (30.46 +/- 3.88) (Student's t-test = 3.64, p = 0.0001). The poorly controlled used of pesticides in the farms appeared to have caused sub-clinical intoxication in the farm workers and indicated the need for training and implementation of hygiene practices.

Intercontinental postmortem studies using interactive television.

For cultural reasons, medical students in the United Arab Emirates (UAE) are not offered postmortem studies. In a collaborative project between the medical schools of Aberdeen University and the UAE University the feasibility, acceptability and effectiveness of telepathology teaching were evaluated. The transmission of postmortem video images at a quality high enough for teaching purposes was achieved at a data transmission speed of 384 kbit/s. Videoconferencing as a method of presentation was viewed by the students as both interesting and useful. All students participating in the telepathology teaching sessions exceeded the minimum acceptable score of 60% in a multiple-choice examination. Although international videoconferencing at 384 kbit/s is expensive, the costs involved in the telepathology project were small in relation to the educational benefits.

A pilot study in medical education using interactive television.

Medical students in the United Arab Emirates do not receive postmortem teaching. This is because postmortems are not normally carried out, for cultural reasons. In order to address this problem a collaborative project was established between the medical schools of Aberdeen University and the United Arab Emirates University to evaluate the feasibility, acceptability and effectiveness of telepathology teaching. A videoconferencing link was established between the UK and the Middle East using ISDN at a transmission speed of 384 kbit/s. Although some technical problems relating to line continuity were encountered, the results relating to feasibility, acceptability and effectiveness were very positive. Although expensive, this form of teaching may still be cost-effective in relation to the benefits.

The nurse practitioner: management of minor trauma.

OBJECTIVE: to identify patient groups within Accident and Emergency (A & E) practice where the nurse practitioner, following agreed protocols and treatment regimes, might make a contribution to patient care; and to describe a possible process of preparation required to introduce nurse practitioners into an A & E department. DESIGN: A 14-day study (6-12 January and 24-30 July 1994) in which the case notes of all patients attending the A & E department were analysed. SETTING: The A & E department of Aberdeen Royal Infirmary, UK. PARTICIPANTS: A census of the case notes of 1785 patients. MAIN OUTCOME MEASURES: Demographic and clinical characteristics of new patients, diagnosis, investigations, treatment ordered, numbers of return visits, source of referrals and disposal destinations. RESULTS: On analyses of the workload profile it became apparent that a small number of injury categories, investigations and treatments, accounted for a significant percentage of patient throughput and that 75% of cases attended between 09:00 and 21:00 h. Many cases were of a minor nature, discharged home after minimal treatment and no follow-up. It was thought possible that the assessment and treatment of a significant percentage of patients (30%) could be carried out by suitably trained and experienced nurses working to an agreed protocol. CONCLUSIONS: The paper discusses the concept of the nurse practitioner and seeks to demonstrate a possible role for such a clinical worker using previously agreed protocols devised from a clinical database of patient requirements. Their employment could possibly bring a considerable routine saving in waiting time for patients with minor injuries.

Telematics in undergraduate teaching.

The use of telematics in the practice of medicine has received much recent attention but little has been written about the use of these techniques in medical education. This is a report of a pilot study in which an interactive video-conference took place between medical students at the UAE University and their opposite numbers at Aberdeen University. In Aberdeen, the Dean of the Medical Faculty simultaneously taught Aberdeen and UAE students on a clinical case. He was able to confine his activities largely to the correction of misconceptions, the emphasis of important points and the addition of missing information, while the students themselves conducted most of the presentation. The UAE students presented their Community Health projects and had a spirited discussion on them with the Aberdeen students. Recent technological advances have so improved the quality of transmission of both visual and auditory images and at reasonable cost, using the ISDN telephone system, that the feasibility of using this medium as an aid to teaching has suddenly materialized. The experiment showed that the technology was adequate for easy, fully interactive teaching among students from different continents and with different cultural backgrounds. It is particularly suitable for the Arab world where it is the custom to teach males and females separately. The pilot study has pointed out the existence of a medium of communication and teaching which, if proved to be effective, could have far-reaching consequences in the undergraduate and postgraduate teaching of medicine.

Research based training for the nurse practitioner.

Exploration for oil and gas began in the North Sea in the mid 1960s. Since that time offshore medics have had the authority to diagnose and treat patients within a set of guidelines. As such they are one of the earliest groups of British nurse practitioners. Training for offshore medics in the UK sector of the North Sea is regulated by the Health and Safety Commission. In order to promote training based on research, a study was conducted to examine the pattern of referrals to the Accident and Emergency department of Aberdeen Royal Infirmary from offshore. This was done for a 9 year period. The purpose was to establish a reliable database of the most frequently occurring injury types and affected body parts, and to use this information to modify existing training courses for offshore medics. The total number of injury referrals during the study was 6270. The most common injury type was fracture/suspected fracture (mean = 50% +/- 3.2%) and the most common body part affected was the hand (mean = 37% +/- 3.7%). This paper indicates the changes which were made to an offshore medic training programme as a result of the research. It is suggested that unless such research is undertaken it is not possible to claim that the training of nurse practitioners, in this case offshore medics, is research based and therefore relevant to the needs of the community being served.

A review of Scottish telemedicine.

Telemedicine services have been provided from Scotland for many years. Initial activities centred on the provision of health care to workers on the oil installations in the North Sea, to mixed-gas divers supporting the oil industry, and to scientific staff in British Antarctic Territory. Other Scottish research work has contributed to space medicine. The remote location of much of the Scottish population is currently the reason for much telemedicine research. This paper reviews the past quarter of a century of telemedicine in Scotland and identifies the principles that have led to success in some challenging locations. The same principles can be expected to apply when telemedicine services are provided more generally.

Medical care and human biological research in the British Antarctic Survey Medical Unit.

Health care in the Antarctic has developed rapidly over the past decade and a system of remote occupational health care has emerged based upon training of the personnel at risk, the existence of increasingly sophisticated systems of communication and the results of ongoing programmes of medical and physiological research. This paper is based upon a report made from the British Antarctic Survey Medical Unit to the Working Group for Human Biology and Medicine of the Scientific Committee for Antarctic Research (SCAR) at its meeting in Hobart in September 1988.

Medical evacuations from offshore structures.

A retrospective study was carried out on medical evacuations from the installations of four major oil or gas producing companies, or both, operating offshore on the United Kingdom continental shelf. The study covered 1976-84 during which 2162 evacuations were recorded. Of these, 137 (7.7%) required the use of a chartered helicopter. In the earlier years of the study there were substantially more injuries sustained than episodes of illness recorded but from 1980 onwards the cases of illness equalled those of injury. Using the International Classification of Diseases, the digestive system was responsible for most evacuations for illness and of those, about half (115 evacuations) were for dental problems. Suspected fractures were responsible for about one third of those evacuated for an injury but injuries of hands and eye conditions were particularly common, accounting for 25% of all evacuations. As the age of the evacuee increased the proportion of evacuations for injury decreased and that for illness increased. The mean age for evacuation for injury was 28.3 years and for illness 34.4 years. Few evacuations were required for those aged over 45.

Post operative stimulation of cell mediated immunity.

The consequences of altered immuno-competence resulting from anaesthesia and surgery are potentially hazardous to the patient with malignant disease. Malnutrition also produces reduction in cell mediated immunity, a condition which is commonly incurred in patients with neoplastic disorders. Numerous agents have been claimed to stimulate the immune responses but few have proved to be of practical value. This paper reports the use variously of protease inhibitors, using Aprotinin, and post operative nutritional therapy, following major surgical resection for carcinoma - specifically as regards their influence on parameters believed to relate to cell mediated immunity. No clinical, metabolic or immunologic benefit was identified from either method of post operative stimulation of cell mediated immunity, although this study did confirm post operative depression of these parameters. The significance of these changes is unclear but there is no evidence to support an immunological mechanism for either of these approaches being of benefit in clinical practice.
