How schools perceive the school health service.

An awareness by health professionals of changing priorities facing the School Health Service (SHS) has led to increased attempts to evaluate current practice. In the present study we set out to examine how schools perceive the SHS, to identify their concerns and obtain their suggestions for improvements. Despite direct and repeated personal communication, only 26 questionnaires were returned out of 64 sent to primary and post primary schools. The majority of responses indicated a lack of knowledge about the various aspects of the SHS and a request for more information. Half the questionnaires indicated dissatisfaction with the current SHS--particular problems identified were poor communication, lack of information and inability to deal with social problems. Suggestions made by schools to improve the SHS include improved communication between schools, SHS and parents, better and increased health education. Schools identified the current health needs of pupils as health education; social, family and behavioural problems; and developmental problems. Overall those schools who responded welcomed the approach from the SHS.

Computer-aided pattern analysis of temperature differentials.

Chiropractic analysis often incorporates the evaluation of heat distribution patterns observed in skin temperature profiles. Historically, temperature recordings of the spine have been made with a heat detection instrument using a thermocouple design. The advent of refinements in infrared technology, however, have greatly enhanced temperature detection in terms of accuracy and reliability. The present research reflects the development of computer software designed to express the data obtained with a dual channel heat sensing instrument. Two phases are involved: a) digital information, received from the sensing instrument, is standardized, stored for future analysis, and retrieved for comparisons with other graphs; b) stored data is graphically displayed, statistically analyzed, and otherwise compared. The data is displayed for visual observation as a) temperature data received from either channel of the sensing instrument or b) relative temperature differences between data from both channels of the sending instrument. For statistical evaluation, corresponding readings (comparisons between graphs) are plotted against one another and analyzed by a moving Pearson Product Moment correlation and moving t-test. This evaluation is graphically represented with a numeric display of pertinent statistical values. Current work indicates that a 10 point moving correlation and t-test will yield accurate comparisons between graphs.

Paraquat poisoning: significance of plasma-paraquat concentrations.

Plasma-paraquat concentrations were measured in 79 patients who had ingested liquid or granular weedkillers containing paraquat. At any given time after ingestion, the plasma-paraquat concentrations in the patients who died usually exceeded those in the survivors. It is suggested that measurement of plasma-paraquat concentrations is useful in assessing the severity and predicting the outcome of poisoning. Patients whose plasma concentrations do not exceed 2.0, 0.6, 0.3, 0.16, and 0.1 mg/l at 4, 6, 10, 16, and 24 h respectively are likely to survive.
