New test series for the functional evaluation of oral cavity cancer.

There are few studies that have addressed themselves to measuring speech, swallowing function and the "quality of life" of patients that have been treated for oral cavity cancer. The goal of this study was to develop a test series to assess the oral cavity function and the general health of patients treated for oral cavity cancer. The results of 51 patients treated for oral cavity cancer will be compared by the site and stage of the lesion, as well as by treatment mode. In addition, the functional results achieved by different reconstructive techniques in the oral cavity will be presented. Radiotherapy patients as a group have the best speech and swallowing function while the patients treated with combined therapy have the worst function. In the surgical group, those patients treated with intraoral skin grafts had the best speech results and those with primary closures had the best swallowing performance.

Disordered eating and unhealthy weight reduction practices among adolescent females.

BACKGROUND: Dissatisfaction with body weight and the use of unhealthy weight reduction practices have been reported among adolescent females. There is a need for methodologically rigorous studies using large representative samples of adolescent females to accurately assess the prevalence of these behaviors and attitudes. METHODS: Eight hundred sixty-nine Australian school girls ages 14-16 years were administered a self-report questionnaire to determine the prevalence of disordered eating behaviors, unhealthy dieting practices, and distorted body image. Anthropometric (height and weight) data were collected on each of these adolescent females. RESULTS: The prevalences of disordered eating, unhealthy dieting, and distorted body image were 33, 57, and 12%, respectively. Over one-third (36%) of the total sample had used at least one "extreme" dieting method in the past month, i.e., "crash" dieting, fasting, slimming tablets, diuretics, laxatives, and/or cigarettes to lose weight. Of the total sample, 77% wanted to lose weight and 51% had tried to lose weight in the past month. Motivating factors for disordered eating and unhealthy dieting behaviors were peer pressure, media pressure, and the perception that extreme dieting strategies were harmless. CONCLUSION: The prevalence of disordered eating and dieting behaviors among adolescent females shown by this study suggests the need for preventive programs encouraging appropriate eating and dieting behaviors.

Molecular site assessment and process monitoring in bioremediation and natural attenuation. off.

A variety of modern biotechnical approaches are available to assist in optimizing and controlling bioremediation processes. These approaches are broad-ranging, and may include genetic engineering to improve biodegradative performance, maintenance of the environment, and process monitoring and control. In addition to direct genetic engineering strategies, molecular diagnostic and monitoring technology using DNA gene probing methods and new quantitative mRNA analytical procedures allows direct analysis of degradative capacity, activity, and response under in situ conditions. Applications of these molecular approaches in process developments for trichloroethylene (TCE), polychlorinated biphenyls (PCB), and polynuclear aromatic hydrocarbons (PAH) bio-oxidation in soils, aquifer sediments, and ground-water treatment reactors have been demonstrated. Molecular genetic technologies permit not only the development of new processes for bioremediation, but also new process monitoring, control strategies, and molecular optimization paradigms that take full advantage of vast and diverse abilities of microorganisms to destroy problem chemicals.

Factors affecting nonadherence with antibiotics.

Nonadherence with antibiotic therapy has profound implications both for patient health and the health care system that bears the financial costs incurred. Significant levels of nonadherence with antibiotic prescriptions have been demonstrated. Of the many proposed variables involved, those that are potentially modifiable relate to aspects of the doctor-patient interaction and drug regimen. Despite the potential for intervention with these variables, there have been very few methodologically sound studies examining their effect on adherence with either medications generally or antibiotics specifically. Only two studies were located that had tested the effectiveness of reduced complexity of antibiotic dosage schedules. The results suggest that the less complex the schedule, the greater is the adherence. Both practitioners and patients must be encouraged to use and accept simpler dosage schedules, preferably once-daily schedules wherever possible. The paucity of well-controlled studies to date highlights the need for further research evaluating intervention strategies that utilize variations in dosage schedule and elements of the doctor-patient interaction to improve adherence with antibiotic medications.

Lack of burning and stinging from a novel first-aid formulation applied to experimental wounds.

Antiseptic-anesthetic first aid formulations typically produce a burning or stinging sensation when used on wounds. The aim of this study was to assess the lack of sting/burn potential of a prototype first-aid wipe when applied to superficial wounds. This was a one-day, double-blind, randomized study, evaluating the stinging/burning sensation from a prototype first-aid wipe with a cellulose base containing 1.0% pramoxine HCL and 0.13% benzalkonium chloride. The study followed a direct comparison test design of four test formulations. The remaining three articles were: (a) sterile 0.9% sodium chloride (no-sting/no-burn control), (b) 3% hydrogen peroxide (first-aid sting/burn control), and (c) 70% isopropyl alcohol (second sting/burn control). The test was performed on 24 subjects. The tape stripping method was used to create four standardized wounds on the volar forearms, reaching the glistening layer. Each test article was applied to the wound for 15 seconds. The subjects were asked to report the intensity of the stinging/burning sensation during the application. The prototype pramoxine-benzalkonium chloride wipe produced significantly less stinging/burning than both 70% isopropyl alcohol and 3% hydrogen peroxide. Also, the prototype wipe did not produce more stinging and burning in superficial wounds compared to the saline control.
