Integrating the community into geriatric case management: public health interventions.

Gatekeepers, or nontraditional referral sources, have proven to be an effective means of case finding and outreach for the mental health needs of isolated senior citizens. A two-year project administered by the Public Health Division of the Health Services Department in a San Francisco Bay Area county found the gatekeeper concept to be an effective means of case finding in the public health setting. Program statistics showed similar profiles of individuals referred by gatekeepers and other referral sources except that gatekeepers referred more individuals living alone.

Effects of metkephamid (LY127623), a selective delta opioid receptor agonist, on gastric function.

Metkephamid, a delta opioid receptor agonist, blocked cold-restraint stress ulcers, reduced absolute ethanol-induced gastric ulcers and, at the lowest and highest doses examined, reduced basal gastric acid secretion in conscious rats, all to a significant degree. The dose effects on stress ulcer formation parallel those seen against maximal electroshock seizures and suggest that both central as well as peripheral delta opioid receptors mediate gastrointestinal responses to stress.

Influence of rearing conditions on voluntary ethanol intake and response to stress in rats.

The effects of exposure to four environmental rearing conditions on subsequent voluntary ethanol intake and response to immobilization stress were examined. Male weanling rats were reared in an enriched environment, with a female partner, with a male partner, or individually, for 90 days. At 111 days of age, voluntary consumption of ethanol in increasing concentrations (3 to 9%, v/v) was assessed. Following the ethanol-exposure period, rats were randomly divided into stressed and nonstressed groups and exposed to 3 h of immobilization. Results indicated that the enriched animals consumed greater amounts of ethanol as compared to all other groups, suggesting that the enriched environment and not handling, housing conditions, or the presence of another male or female is responsible for the observed increase in ethanol drinking behavior. Ulcer data indicated that among environmentally enriched rats, ethanol attenuated stress ulcer development relative to their non-ethanol-exposed but stressed controls. In nonstressed enriched rats, ethanol alone exacerbated stomach damage. We suggest that environmental rearing conditions markedly influence the complex interaction between ethanol intake and the response to stress.

Evidence of "cross-stressor"-induced adaptive gastric cytoprotection.

Rats were given 7 days pre-treatment with either water (p.o.), 1 h immobilization or 20% ethanol (p.o.) with or without concomitant indomethacin injection. Following the pre-treatment phase, rats from each pre-treatment group were exposed to either 3 h cold-restraint stress or to 100% ethanol p.o. Results indicated that immobilization and 20% ethanol pre-treatment significantly reduced both cold-restraint stress ulcer formation and 100% ethanol-induced ulcers. Indomethacin co-treatment attenuated the reduction of ulcer formation of both pretreatments. These results suggest that "cross-stressor" adaptive cytoprotection occurs. Indomethacin abolished these effects, implicating the involvement of endogenous prostaglandins in the mediation of "cross-stressor"-induced gastric cytoprotection.

Diabetic retinopathy and insulin therapy in a rural diabetic population.

The prevalence of diabetic retinopathy was lower in a rural diabetic population when compared to the prevalence of diabetic retinopathy in medical center clinic populations. Adult-onset (Type II) diabetics were at greater risk for developing diabetic retinopathy shortly after diagnosis than newly diagnosed cases of juvenile diabetes (Type I). The use of insulin positively correlated with the prevalence of diabetic retinopathy in this rural population.

Lung function in healthy British women.

The forces expiratory volume, total lung capacity, transfer factor (diffusing capacity), and their subdivisions have been measured in 113 healthy British women aged 27 to 74 years of whom 47 were current smokers and 66 were lifetime non-smokers. The results have been analysed in terms of age, stature, mass, body fat, and smoking. In addition to their relation to stature and to age, the inspiratory capacity was positively correlated with indices of body muscle while the residual volume, expiratory reserve volume, and total lung capacity were inversely correlated with the percentage of body mass that is fat or with mass divided by the square of stature. The inverse correlation between total lung capacity and age was apparently due to the quantity of body fat increasing with age. The transfer factor and its subdivisions were inversely correlated with smoking. In this study the forced expiratory volume and vital capacity were independent of both fat and smoking; the transfer factor was independent of the physiological response to exercise. The results provide reference values for lung function in British women.

The solitary bone cyst. Report of two cases.

Two cases of solitary bone cyst are described. Case 1 is interesting in that the age of presentation was near the extreme lower end of the range of recorded cases, and also the site was in the mandibular ramus, extending to the sigmoid notch, which is one of the least common sites in this bone. Furthermore, the lesion was not clinically silent; 26 per cent of Howe's series had swelling with or without pain, and 24 per cent of Huebner's and Turlington's series. Cases 2 illustrates the value of radiographs which give a general view of the mandible and maxilla, since this particular lesion was quite unexpected. Although the etiology is still dispute, the treatment by surgical intervention is almost universally agreed upon.
