Facing up to binge drinking: reducing binge drinking in adolescent males.

OBJECTIVE: To evaluate the effectiveness of an orofacial trauma-based brief intervention, designed to raise adolescent males' awareness about the immediate dangers of binge drinking. DESIGN: Non-randomised controlled exploratory trial. SETTING: Secondary level schools. MATERIALS & METHODS: Pre, post and follow up validated questionnaires were used to assess a variety of descriptive data and changes in behaviour. Sixty Year 12 students were recruited in the pilot study and 182 in the definitive study. INTERVENTION: A brief visual presentation containing salient information and anonymised photographs relating to orofacial injuries. MAIN OUTCOME MEASURES: Intention to binge drink. RESULTS: The majority of participants obtained alcohol from off-licence or licenced premises. At the commencement of the study, 68% of the participants were regular drinkers. Whilst there was no change in drinking behaviour, the intervention group reported that it was significantly more likely (compared to the control group) that they would reduce their drinking to less than binge levels. CONCLUSION: The intervention resulted in participants reporting a more negative attitude towards binge drinking and increased their intention to disengage from binge drinking.

An educational model to introduce staff nurses to continuous quality improvement/total quality management concepts.

A new healthcare reforms are implemented and as the Joint Commission on Accreditation of Healthcare Organization standards are revised, the demand for continuous quality improvement/total quality management in acute care settings continues to rise. In this article, the authors describe the process used to introduce nursing staff to continuous quality improvement/total quality management. A curriculum committee of staff nurses, nurse educators, and clinical specialists used the continuous quality improvement process to develop a 1-day program that included didactic and experiential activities geared toward assisting the staff nurse to participate actively in total quality management initiatives.

A light microscopic study of oogenesis in the brushtail possum Trichosurus vulpecula.

Ovaries from young of the brushtail possum, Trichosurus vulpecula, were examined histologically and histochemically to determine stages of oogenesis. Groups of dividing oogonia were first present in a 13-day-old pouch young, with extensive oogonial proliferation after about 23 days of age. Meiosis was initiated in some oogonia by 48 days of age, and by 88 days numerous early primordial follicles were present. The first primary follicles had formed by 103 days of age. In oocytes of quiescent primordial follicles, dark granular material, which stained positively for protein, mainly occupied the perinuclear cytoplasm. Associated with the transition to primary follicles and continuing throughout oocyte growth was the production within the central cytoplasm of large clear vesicles and, to a lesser extent, lipid-like yolk bodies. The former were analogous to similar vesicles found in other species of marsupial, and have a putative role in development of the blastocyst. By contrast, yolk-like bodies are not found in all marsupial oocytes and their importance in development is unknown.

The influence of flavor and color on drink identification by children and adults.

This study investigated how color and flavor influences drink identification by children and adults. The children ranged in age from 2 to 18 years of age. Each subject tasted four drinks that differed in color and flavor. Each drink had an atypical color-flavor pairing (e.g., brown-pineapple) or a typical pairing (e.g., brown-chocolate). After tasting each drink, the subject chose which of four flavor names identified the drink. For the atypical drinks, the selection of color-associated names (e.g., chocolate for a brown drink) decreased, and the selection of flavor-associated names increased with age from the preschoolers to the adults. For the typical drinks, the selection of the correct name was greater than 80% for all ages. These results suggest that drink identification becomes more influenced by flavor as children get older because of an increase in the ability of children to focus on flavor as their perceptual-attentional skills mature.

Association between malignancies of the upper aerodigestive tract and uterine cervix.

Cancers of the cervix and buccal cavity share histologic, epidemiologic, and exposure characteristics. In particular, cigarette smoking and human papillomavirus (HPV) have been cited as etiologic cofactors of both malignancies. Using incidence data from the Surveillance, Epidemiology, and End Results (SEER) program of the National Cancer Institute for the years 1973 through 1984, we evaluated the incidence of second cancers of the buccal cavity following an initial cervical cancer. Standardized incidence ratios (SIR) were uniformly elevated for both white (SIR = 2.0), and black (SIR = 3.5) women. There were also elevated risks for the development of cervical cancer following an initial buccal cavity cancer (SIRs = 3.3 and 2.5, respectively). A similar pattern was evident for laryngeal cancer among white women. HPV transmission could account in part for the paired occurrence of these two anatomically distinct cancer sites. Cigarette smoking could act as a synergistic cofactor in the malignant transformation of viral genome-harboring tissue.

Cancer control and the older person. Prevention and detection in older persons.

Older persons are appropriate targets for a range of prevention and early detection interventions, however, greater emphasis should be given to structuring the delivery of prevention and detection services to the special needs of this population. This may require research and program development to reach older persons in the most effective and cost-effective manner. The American Cancer Society and other program efforts must accommodate the heterogeneity and special needs of segments of the older population. Racial and cultural minorities, impoverished persons, the cognitively impaired, and the physically impaired are four groups requiring special attention. Early detection guidelines specific to older persons should be developed.

Familial patterns of prostate cancer: a case-control analysis.

Epidemiological data have not yet enabled physicians to look beyond age and race to identify men at increased risk for prostate cancer. We conducted a hospital-based case-control study of familial patterns of prostate cancer with self-reported data from a risk-factor questionnaire. There were 385 patients with histologically confirmed prostate cancer, and 385 race and age-matched (+/- 5 years) controls with other cancers. Family history, available for 378 patients and 383 controls, was positive for prostate cancer in 13.0% versus 5.7%, respectively. The difference was significant at p = 0.01. The over-all age-adjusted risk estimate for men with a first-degree relative with prostate cancer was significantly elevated (odds ratio of 2.41), as were the individual risk estimates for having a father or brother with prostate cancer (odds ratio of 2.24 and 2.66). Having a second-degree relative (grandfather or uncle) with prostate cancer also conferred elevated but not statistically significant risk. These data accord well with the few previously published case-control studies of familiarity of prostate cancer. On the basis of these findings, one should consider recommending participation in early detection programs for prostate cancer in a man whose father or brother has had the disease.

Risk profiles of women with cervical neoplasia.

Risk-factor profiles were compared in M.D. Anderson Cancer Center patients with various uterine cervix histologic diagnoses. Intraepithelial neoplasia (n = 171) and condyloma (n = 82) were associated with significantly lower patient age (mean 23.6 and 25.8 years, respectively). In addition, these two groups were lowest in annual income, age at beginning intercourse and at first pregnancy, and highest in percentages of black and Hispanic patients, number of sexual partners, and history of gonorrhea. Women with squamous carcinoma in situ (n = 47), who were about a decade older, exhibited a similar socioeconomic distribution and sexual history. All three groups also reported high prevalences of current smokers, were most likely to use oral contraceptives, and were least likely to use diaphragms or condoms. Patients with invasive squamous cell carcinoma (n = 77) had a mean age of 46.3 years, a large lowest-income constituency, and the highest mean number of pregnancies; they were least likely to have used oral contraceptives. Adenocarcinoma (n = 21) was epidemiologically distinct: a predominance of white woman characterized by high socioeconomic status, elevated body mass index, and non of the liberal sexual practices of the other groups. Primary and secondary prevention strategies must be tailored to the unique needs and socioeconomic status of the young at-risk populations.

History of cigarette smoking and risk of leukemia and myeloma: results from the Adventist health study.

The risks of leukemia and myeloma associated with cigarette smoking were evaluated in a cohort study of 34,000 Seventh-day Adventists. Although Seventh-day Adventists do not smoke by church proscription, many are adult converts who smoked cigarettes prior to their baptism into the church. In comparison with those who never smoked, ex-smokers experience a relative risk of 2.00 (95% confidence interval = 1.01-3.95) for leukemia and 3.01 (95% confidence interval = 1.13-8.05) for myeloma. Risks increased in a dose-response fashion with increasing numbers of cigarettes smoked daily for both leukemia (trend P = .009) and myeloma (trend P = .005). Also, the risks of both leukemia and myeloma increased with the total duration of cigarette smoking. The cigarette smoking-leukemia relationship was strongest for myeloid leukemia, for which ex-smokers experienced a relative risk of 2.24 (95% confidence interval = 0.91-5.53). These data lend support to the hypothesis that cigarette smoke may induce malignant degeneration in bone marrow and its products.

Salivary gland cancer. A case-control investigation of risk factors.

Unlike most upper aerodigestive tract cancers, salivary gland cancers are relatively infrequent, are characterized by a diversity of histologic subtypes, and have never been etiologically associated with tobacco exposure. We present the results of a case-control study of risk factors for these cancers, with risk estimates derived from self-administered comprehensive risk-factor questionnaires distributed to patients at The University of Texas M. D. Anderson Cancer Center, Houston. Cases were 64 patients with histologically confirmed salivary gland cancer. Control subjects, randomly selected from the same patient population excluding patients with cancer of the head and neck or nonmelanoma skin cancer, were frequency-matched to the cases by age, sex, and ethnicity to achieve a 2:1 control subjects/cases ratio. On multivariate analysis, prior radiotherapy was a significant risk factor for both men (odds ratio [OR] = 2.1) and women (OR = 2.3). Among women, higher educational attainment (OR = 2.4), alcohol use (OR = 2.0), and hairdye use (OR = 2.5) were also significantly associated with risk. There were no significant differences between cases and control subjects with respect to tobacco exposure or specific occupational or leisure-time exposures. There is biological plausibility for associations with hairdye use and alcohol exposure.

Salivary gland cancer and risk of subsequent skin cancer.

There are epidemiologic similarities between salivary and skin neoplasms that could be attributed to exposure to ultraviolet radiation. To explore further the etiologic parallels between these two types of cancer, we studied the multiple primary association between salivary gland cancer with that of other cancers known to be induced by ultraviolet light exposure, using data from the SEER program for 1973-1984. Because nonmelanoma skin cancers other than cancers of the lip are not routinely reported to the SEER registries, we specifically evaluated the associations with melanoma and lip cancers. Expected numbers of subsequent primaries (melanoma and lip) for the 904 white men and 784 white women with an initial salivary gland cancer were computed from incidence rates using the Connecticut Tumor Registry. There were significantly increased risks for subsequent lip cancer among men (RR = 8.7) and for melanoma among women (RR = 7.1). Among men there was also a significant association between an initial lip cancer and risk of subsequent salivary gland cancer (RR = 12.7). These observations, together with reported increases in incidence of these tumors, suggest a common etiology, which could partly be explained because of exposure to ultraviolet radiation.

Cigarette smoking patterns in patients after treatment of upper aerodigestive tract cancers.

There is a paucity of data on variables predictive of successful smoking cessation in cancer patients. In this questionnaire-based study, we report the smoking status of 75 patients (46 men, 29 women) with head and neck cancer followed for a minimum of 30 months after definitive therapy. Seventy-one percent of the men and 61% of the women who were current smokers at diagnosis stopped smoking subsequent to diagnosis and treatment. Only 29% and 39%, respectively, continued to smoke, most at decreased intensity. Patients with laryngeal cancer were most likely to have stopped (83%). Conversely, patients with oral cavity cancer were most likely to be continuing smokers (66%). In addition, older age, college education, and lighter smoking habits were somewhat predictive of successful cessation. Fear of recurrent disease and physician advice were the questionnaire-listed incentives most often chosen as contributing to success in cessation. The role health professionals can play in counseling cancer patients to stop smoking is stressed.

Self-concept as a factor in the quality of diets of adolescent girls.

The effect of self-concept on the quality of diets of adolescent girls was investigated. Scores for self-concept as measured by the Tennessee Self Concept Scale (TSCS) and fat area values were obtained from 160 15-year-old girls. Twenty-four-hour dietary recall interviews were conducted with a random subsample of 40 girls. Mean dietary adequacy ratios (MARs) were calculated to assess dietary quality. Girls in this study had larger arm fat areas than did their national counterparts. Mean intakes of energy and nine nutrients met or exceeded their respective RDAs except for vitamin A, calcium, and iron. MAR values were correlated positively with Self-Satisfaction scores and negatively with carbonated beverages, candy, and baked desserts. Fat area values were correlated negatively with Physical Self scores. Significant predictors of MAR values below 80% were Total Conflict, Moral-Ethical Self, Family Self, Identity, and Physical Self scores.

Chromosome sensitivity to bleomycin-induced mutagenesis, an independent risk factor for upper aerodigestive tract cancers.

Defective DNA repair capability, measured by enumerating mutagen-induced chromosomal lesions, might explain variable host susceptibility to the action of environmental carcinogens. We compared sensitivity to bleomycin-induced chromosome damage in 75 patients (53 men and 22 women) with previously untreated upper aerodigestive tract malignancies with that in 62 healthy control subjects. Data on tobacco and alcohol use were derived from a detailed, self-administered cancer risk factor questionnaire. Forty-five patients and 13 controls were sensitive to bleomycin-induced mutagenesis (average breaks/cell greater than 0.8). Differential susceptibility was detected in patients categorized by primary tumor location. Odds ratios for chromosome sensitivity were significantly elevated for all sites (odds ratio = 10.3 for pharyngeal cancers, 8.0 for laryngeal cancers, and 3.8 for oral cavity cancers). On logistic regression analysis, chromosome sensitivity remained a strong and independent risk factor after adjustment for potential confounding from age, sex, and tobacco and alcohol use (odds ratio = 4.3, 95% confidence limits = 2.0, 10.2). Despite the small study size and design constraints, the strength of the association with chromosome sensitivity even after adjustment for potential confounders is impressive and suggests a promising avenue for further research. The preventive implications of a valid marker for carcinogen sensitivity are manifold.

Food group contributions to nutrient intake in whites, blacks, and Mexican Americans in Texas.

The existence of three different ethnic groups, living within a defined geographic area in Texas and maintaining fairly distinct life-styles, provided an excellent opportunity to compare their dietary behaviors. Information about food consumption was obtained by 24-hour dietary recall from a group of 431 whites, blacks, and Mexican Americans residing in two counties in southeast Texas. Food group and subgroup contributions to 11 nutrients were calculated. The intake patterns of Mexican Americans demonstrated both an adherence to traditional or familiar Mexican food items, such as beans and tortillas, and a preference for foods not previously reported to be commonly consumed by that ethnic group, specifically beef. The current study provides a base of information necessary to implement dietary changes acceptable within the context of a particular culture's world view. Results revealed differences in food intake patterns that would be helpful in designing practical nutrition education programs specifically targeted toward these ethnic groups. For example, inadequate sources of nutrients were identified, as were sources of excess fat.
