Discussion: what does it all mean?

Offsetting the current tendency toward "life-course reductionism," insights from these papers illustrate a broader ("aging and society") paradigm--one that includes the life-course perspective, but also complements it with deeper understanding of the dialectical interplay between changes in lives and changes in the surrounding social structures.

Proterometra macrostoma (Digenea: Azygiidae): variations in cercarial morphology and physiology.

Snails, Elimia semicarinata, infected with Proterometra macrostoma were collected monthly in 1990 and 1991 from North Elkhorn Creek near Lexington, Kentucky, and kept on a 12:12 h light-dark cycle for 2 weeks. Cercariae emerging from snails were classified into 8 strains (I-VIII) based on differences in number and distribution of spined and spineless papillae on the tail. Cercariae also had unique patterns of emergence, swimming behaviour and infectivity in 4 species of sunfish. Of 513 infected snails collected in May, 339 had pure infections with the strain frequencies (% of 339): I, 46.6; II, 7.7; III, 12.1; IV, 8.8; V, 0.6; VI, 2.7; VII, 11.8; VIII, 9.7. In the multiple infections, 159 snails shed 2 strains, 14 shed 3, and 1 snail shed 4 strains simultaneously. A comparison of sunfish and parasite populations in Kentucky, Ohio and Michigan indicated that strain frequency in P. macrostoma is regulated by the species composition of the sunfish population.

Wrist squareness and median nerve impairment.

Previous research indicated that a wrist-squareness ratio (thickness/width) greater than .7 is likely to indicate a median nerve sensory latency greater than 3.7 ms, usually a predictor of carpal tunnel syndrome (CTS). In this study, wrist thicknesses and widths were measured and wrist-squareness ratios were calculated for a sample of 417 railroad maintenance workers. Electrodiagnostic testing, in accordance with American Academy of Electrodiagnostics Medicine guidelines, was performed on both motor and sensory fibers of the median nerve to evaluate subjects for the presence of median nerve impairment typical of CTS. Results of this study indicate that wrist squareness is not a useful predictor of median nerve impairment typical of CTS in the railroad maintenance workers tested.

Age integration and the lives of older people.

This research-based essay argues, as a stimulus to Forum discussion, that our currently age-differentiated society will give way to an age-integrated one. Age will lose its power to constrain people's entry, exit, and performance in such basic social institutions as education, work, and retirement. Revolutionary changes toward age integration are needed to reduce the "structural lag," in which the dynamism of human aging is outpacing the dynamism of structural change. To guide these changes, aging research is beginning to complement existing knowledge about human lives with new and deeper understanding of the social structures which shape and are shaped by these lives.

Introducing the "oldest old".

The mounting numbers of the very old--their percentage of the population will double in the next 15 years--is so new a phenomenon that there is little in historical experience to help in interpreting it. Not only are the older living longer, but they are also growing older in markedly different ways from their predecessors. The work at hand, still partial and tentative, indicates that the oldest old can no longer remain invisible in the economy, the polity, the health care system, or the statistical records.

Reducing 'information overload' in the teaching of pharmacology: the '200 Drug List'.

The author in this report describes the development and use of a restricted list of drugs in the medical pharmacology course at the Medical College of Georgia (MCG) School of Medicine. The "200 Drug List" was developed by the author by analyzing recent examinations given to students at the MCG and other places. The list contained 60 percent fewer drugs than had been taught in the course in prior years. Only those drugs on the list appeared on subsequent pharmacology examinations, regardless of the scope of the teaching program. Despite the limited number of drugs that the students were required to learn to satisfy the requirements of the teaching program, the average score for the class on the pharmacology subtest of the National Board of Medical Examiners Part I examination improved each year since the new approach was adopted. The 200 Drug List concept is viewed as an effective way to reduce the "information overload" for students without sacrificing the quality of an introductory course in pharmacology.

Developing Drug Reports for the Pharmacy and Therapeutics Committee.

The role of a drug information center in working with a pharmacy and therapeutics committee is discussed. In order to add a drug to the formulary, physicians must complete a special form which asks for justification for the addition. In preparing a report for the pharmacy and therapeutics committee, the drug information pharmacist evaluates the request as it relates to: (1) the effectiveness of the drug in the stated anticipated uses, and (2) studies comparing the requested drug with similar drugs already in the formulary. Use of the form permits the pharmacist to focus on the specific claims made by the physician who is requesting the formulary addition.
