Conceptualizing and scaling the developmental structure of behavior disorder: the Lifetime Alcohol Problems Score as an example.

We contrast the current, clinically based framework for behavior disorder against a life course framework, as an alternative structure upon which to map the variations in onset and stability of clinical symptomatology known to take place in adult life. This alternative developmental framework is used as a base around which to understand known variations in rates of alcohol abuse/dependence over the life course and to review existing schemes for the evaluation of developmental variation in "caseness." From this work, it was proposed that symptom structure be regarded as a mass of greater or lesser breadth, with properties of extensiveness in time and life course invasiveness, as a function of where in the life course the symptomatology first emerged, and the degree to which the mass sustained itself in developmental time. This framework guided the construction of a time-based measure of alcohol related symptomatology, called the Lifetime Alcohol Problems Score (LAPS). The LAPS discriminated among a variety of alcohol-specific and nonalcohol-specific measures of alcohol-related difficulty, including diagnosis of alcohol dependence, having been in treatment, level of other psychopathology, and measures of family disorganization. The measure has potential applicability for prospective studies, and in estimating clinical prognosis. The utility of the paradigm as a framework within which to conceptualize the emergence, ebb, and flow of other behavior disorders is also discussed.

Alcohol schema acquisition in preschoolers: differences between children of alcoholics and children of nonalcoholics.

Cognitive schemas provide the structure within which children organize their knowledge and beliefs about the use of alcohol. The development of schemas about alcohol should be affected both by age and parental patterns of alcohol use. We examined differences in alcohol schema development among 139 male children of alcoholics (COAs) and 82 controls [children of nonalcoholics (NCOAs)] utilizing the Appropriate Beverage Task as an indicator of these processes. Overall, the vast majority of the sample identified at least one alcoholic beverage from photographs, even at age 3. COAs were more likely to identify at least one alcoholic beverage. With age controlled, COAs were better able to identify specific alcoholic beverages and correctly identified a larger number of alcoholic beverages. There was a trend for these children of alcoholic men to attribute more alcoholic beverage use to male adults than NCOAs. Moreover, differences in these children's attributions of alcoholic consummatory behavior were predicted by their parents' current consumption levels. Results provide evidence that alcohol schemas are detectable in early childhood and are more common in children from alcoholic homes. Discussion focuses on the potential relevance of these risk attributes to the development of more fully formed alcohol expectancies and to the later emergence of alcohol-related difficulty.

Breast reconstruction: a review.

Remarkable advances have been made in the field of breast reconstruction, especially since general surgeons, patients, and the community as a whole have become more knowledgeable and accepting. This has provided an impetus for plastic surgeons to develop better techniques, many of which are reviewed here. In general, less time now elapses between ablative and reconstructive surgery, and frequently reconstruction follows immediately. Procedures requiring fewer steps with less donor and recipient site morbidity are favored for both the mound and nipple areolar reconstruction. There is a definite trend toward submuscular implantation to minimize the negative effects of capsular contracture. With a deficiency of skin or muscle, the trend is toward using musculocutaneous flaps primarily, latissimus dorsi, and more recently the rectus abdominis flap. Occasionally, microvascular flap reconstruction is indicated for extensive chest wall defects, e.g., postirradiation injury. Reconstructed breasts are not capable of nourishment, frequently are not erogenous , and most often are not as pleasing to the eye as the contralateral breast. Yet reconstruction has, in the majority of cases, improved the quality of life for those women who have developed breast cancer and offered hope to those women in a high-risk category for developing breast cancer. To those ends, the search for the perfect breast reconstruction will continue.

Inhibition of cartilage breakdown by hydrocortisone in a tissue culture model of rheumatoid arthritis.

Bovine nasal cartilage discs cocultured with human rheumatoid synovial membrane or synovial-membrane-conditioned media release proteoglycan largely as a result of cartilage breakdown. We assessed the effects of hydrocortisone on proteoglycan distribution between cartilage and culture medium, and on cartilage breakdown expressed as the release of either proteoglycan or 35S-products from prelabelled discs. The presence of synovial membrane inhibited the capacity for net proteoglycan synthesis, preventing its accumulation in cartilage; this was little affected by hydrocortisone. The major response to pharmacological concentrations of hydrocortisone was suppression of both spontaneous and synovial-membrane-induced cartilage breakdown. The autolysis of synovial protein that normally occurred during culture was similarly prevented by comparable doses of corticosteroid. Changes in chromatographic distribution of the 35S-labelled degradation products released from cartilage conformed with a corticosteroid-induced inhibition of endogenous lysosomal or related proteinase activity. Additionally, inhibition of the early events in synovial membrane that are responsible for chondrocyte-mediated breakdown of cartilage may contribute significantly to the overall corticosteroid effect.
