Evaluation of an intervention system for parents of children with intellectual disability and challenging behaviour.

BACKGROUND: Signposts is a flexible intervention system for families of children who have intellectual disability and challenging behaviour. The Signposts materials include eight information booklets, a workbook and videotape for parents, and a series of instructional manuals for therapists. The system was designed so that it can be delivered in several different ways, i.e. group support, telephone support and self-directed modes. METHODS: The present study was an evaluation of these three modes of delivery and involved 115 families. RESULTS: Following the use of the Signposts materials in parent training programmes, the subjects reported that they were less stressed, felt more efficacious about managing their children's behaviour, were less hassled about meeting their own needs and that their children's behaviour had improved. Additionally, families generally reported high levels of satisfaction with the content and delivery of the materials. CONCLUSIONS: Finally, there were minimal differences among the three modes of delivery on the measures used, although families who used the self-directed mode were less likely to complete the materials. Implications of these results for service delivery are discussed.

National Alliance for Oral Health Consensus Conference on Medically Necessary Oral Health Care: Legal issues.

This paper examines medical malpractice law as it applies to medically necessary oral health care. The basic legal concepts and reported cases involving medically necessary oral health care are reviewed. It is concluded that dental professionals and consumer advocates must advance their educational and legislative advocacy efforts so that health professional colleagues and the public will become aware of the importance of these services and insurers will routinely include coverage of medically necessary oral health care in their medical and dental policies. While failure to provide medically necessary oral health care can be violative of patient rights and legally actionable, medical malpractice litigation should always be the behavior modifier of last resort.

Correlation between the effects of aspirin and dipyridamole on platelet function and prevention of intimal hyperplasia in autologous vein grafts.

Fifty-four adult mongrel dogs receiving a lipid-supplemented diet were used to determine the effects of aspirin and dipyridamole on vein graft intimal hyperplasia. Twenty-one animals received the diet alone, 17 animals received a combination of dipyridamole and aspirin, while a further 16 animals received dipyridamole. Segments of undistended external jugular vein were anastomosed to bilaterally-divided femoral arteries. The vein grafts were harvested at six weeks and intimal thickness was measured with a Zeiss computerized microscope. Serum cholesterol, prothrombin time, partial thromboplastin time and clotting time was measured before the diet and at two, four and six weeks after operation. Plasma thromboxane B2 (TXB2) and the metabolite of prostacyclin I2 (6-keto PGF1 alpha) were determined by radioimmunoassay before and four weeks following operation. A similar and significant increase in serum cholesterol was observed in all animals receiving lipid supplementation. Platelet counts were significantly decreased in those animals receiving a combination of aspirin and dipyridamole while all other hematological parameters remained unchanged. Plasma TXB2 and 6-keto PGF1 alpha were unaffected by dipyridamole but were significantly decreased in those animals receiving the combined drug regimen. Intimal thickness measured 59 +/- 6 micron at six weeks in the controls. Dipyridamole reduced intimal thickness to 26 +/- 2 micron while aspirin and dipyridamole decreased intimal thickness to 28 +/- 2 micron. The data indicate that dipyridamole was as effective in reducing smooth muscle cell proliferation as the combination of aspirin and dipyridamole. Furthermore, the data suggest that antiplatelet drug regimens may reduce intimal thickening in autologous vein grafts by a mechanism other than affecting the thromboxane:prostacyclin ratio.
