Chronic Obstructive Pulmonary Disease hospitalization rates in Massachusetts: a trend analysis

BACKGROUND

Chronic Obstructive Pulmonary Disease (COPD) causes a huge economic burden and >80% of COPD cases are attributable to smoking. Massachusetts introduced a comprehensive Tobacco Control Program (MTCP) in January 1993. A trend analysis of COPD hospitalization rates might indirectly reflect the potential impact of such comprehensive tobacco control programs.

METHODS

Age-adjusted COPD hospitalization rates/100,000 was abstracted from the Massachusetts Community Health Information Profile Database between 1989 and 2005. Joinpoint Regression Analyses program was employed to estimate annual percent changes (APC) in COPD rates by age, sex and race.

RESULTS

In 1989, 265/100,000 age-adjusted COPD hospitalization rates were reported that increased to 423/100,000 in 1993, and then declined to 329/100,000 in 2005. A significant annual decline of 5.6 percentage points was observed in overall COPD rates from 1993 onwards. A similar temporal pattern, with an age-gradient and a slower annual decline in female COPD rates relative to male COPD rates, was observed. COPD rates in both Blacks and Whites were similar to the general overall pattern. Such consistent annual declines in COPD hospitalization rates from 1993 onwards in Massachusetts also closely correspond to the introduction of the MTCP in January 1993.

CONCLUSION

The findings indirectly suggest that smoking cessation should remain the cornerstone strategy for the prevention and control of COPD burden. However, additional studies across different population settings are essential for a definitive conclusion with regard to the immediate impact of a comprehensive tobacco control program on COPD hospitalization rates showing possible gender susceptibility.

Secular trends in adult male smoking from 1992 to 2006 in South Korea: age-specific changes with evolving tobacco-control policies

OBJECTIVES

For years, South Korea has had one of the highest levels of tobacco use among males in the world, but a steady decline has been observed recently. This study examined how the smoking behaviour of male adults changed with age after the implementation of national tobacco control policies in 1995.

STUDY DESIGN

Repeated cross-sectional study using a national survey.

METHODS

Data were obtained from the 1992, 1995, 1999, 2003 and 2006 results of a repeated cross-sectional survey, the Social Statistics Survey. The smoking status of adult men was compared before (1992 and 1995 surveys) and after (1999, 2003 and 2006 surveys) the implementation of government-directed tobacco control policies using graphical methods and logistic regression analysis.

RESULTS

After the implementation of tobacco control policies, the percentage of current male smokers decreased while the percentage of former smokers increased markedly. Smoking prevalence among older men (aged 50 years or more) reduced initially, and this decline was more pronounced after the tobacco control policies were implemented. Smoking prevalence in younger men (aged 30-49 years) declined in 2003 when more comprehensive tobacco control policies were implemented.

CONCLUSIONS

This study suggests that comprehensive tobacco control policies in South Korea reduced smoking prevalence among males, initially among older men and later among both older men and younger men.

Reliability and validity of systemic lupus activity measure-revised (SLAM-R) for measuring clinical disease activity in systemic lupus erythematosus

New clinical scales for semiquantitating disease activity in systemic lupus erythematosus (SLE) are widely used in research. They are reliable and valid measures. One of the original scales, the Systemic Lupus Activity Measure (SLAM), has been modified based on experience with it in multi-observer studies and training of individuals in its use. We tested the psychometric properties of the revised SLAM (SLAM-R). SLAM-R was tested on 30 SLE patients, who fulfilled 1997 revised ACR criteria and were selected to represent a range of disease activity. The patients were evaluated independently by two physicians, who studied the instruction booklet and who had never used SLAM-R, on two occasions 2-4 weeks apart. At the first visit, the physician's global assessment of activity using visual analog scale, anti-dsDNA Ab, C3 and C4 were checked for construct validity. The psychometric properties were analyzed with nested analysis of variance and Pearson's correlation coefficient using SAS. All patients were female, the median age was 31 (15-52) y, and the mean score of SLAM-R was 10.5 +/- 5.3 (3-26). Estimates of reliability were 0.78 of inter-rater, 0.61 of inter-visit, 0.76 of physician 1 between visits, and 0.56 of physician 2 between visits. Among subcategories except 'Eye,' the 'Gastrointestinal' category had the highest (0.96) and the 'Neuromotor' category had the lowest inter-rater reliability (0.50). With respect to construct validity, the correlation of SLAM-R scores with the disease activity variables except C4 was high and statistically significant. In conclusion, the SLAM-R is reliable and valid for measuring clinical disease activity in SLE.

FcgammaRIIa/IIIa polymorphism and its association with clinical manifestations in Korean lupus patients

The aim of this study was to determine the distribution of the FcgammaRlla and FcgammaRIIIa polymorphisms and their association with clinical manifestations in Korean lupus patients. Three hundred SLE (systemic lupus erythematosus) patients (48 male, 252 female) meeting 1982 ACR criteria and 197 Korean disease-free controls were enrolled. Genotyping for FcgammaRlla 131 R/H and FcgammaRIIIa 176 F/V was performed by PCR of genomic DNA using allele-specific primers and the FcgammaRIIIa genotype was confirmed by direct sequencing of PCR product in some cases. There was significant skewing in the distribution of the three FcgammaRIIa genotypes between the SLE and the controls (P=0.002 for R/R131 vs R/H131 and H/H131, OR 2.5 (95% Cl 1.4-4.5), but not in FcgammaRIIIa genotypes. FcgammaRIIa-R allele was a significant predictor of lupus nephritis, as compared with SLE patients without nephritis (P=0.034 for R131 vs H131, OR 1.4 (95% Cl 1.03-1.9)), but proliferative nephritis (WHO class III and IV) was less common in patients with FcgammaRlla-R/R131 and in FcgammaRIIa-R allele. In 300 SLE patients, high binding allele combination H131/V176 was less common in SLE with nephritis than in SLE without nephritis. Hemolytic anemia was less common in R131/F176 allele combination among four FcgammaRIIa/FcgammaRIIIa allelic combinations. Male SLE patients showed a higher frequency of renal involvement, serositis, thrombocytopenia, malar rash and discoid rash than female SLE, and male SLE had a higher frequency of FcgammaRIIa-R/R131 or R131-allele than male controls, but FcgammaRIIa or FcgammaRIIIa genotypes had no association with renal involvement in male SLE patients. FcgammaRIIa-H/H131 showed a higher frequency of hemolytic anemia and less pulmonary complications in male SLE. Female SLE patients showed higher frequency of any hematologic abnormality, lymphopenia, anticardiolipin antibody (+) and anti-Ro antibody (+) than male SLE, and had earlier onset of first symptoms. There was no skewing in FcgammaRIIa or FcgammaRIIIa genotypes between female SLE and female controls, but FcgammaRIIa-R131 allele showed skewing between female SLE with nephritis and female SLE without nephritis. The age at onset of thrombocytopenia was earlier in FcgammaRIIa R/R131 among three FcgammaRIIa genotypes, and serositis in FcgammaRIIIa-F/F176 among three FcgammaRIIIa genotypes. FcgammaRIIa-R131 homozygote was a major predisposing factor to the development of SLE and FcgammaRIIa-RI31 homozygote and R131 allele were a predisposing factor, and H131/V176 was a protective allele combination in lupus nephritis. In contrast to other ethnic patients, in our study cohort, clinical manifestation was different between male and female, and FcgammaRIIa and FcgammaRIIIa showed somewhat different clinical associations between the genders.

Sun protection practices in preadolescents and adolescents: a school-based survey of almost 25,000 Connecticut schoolchildren

Sun protection practices in children and adolescents fall well below national recommendations. We present the results of a survey of sun protection use and other health-related behaviors in a sample of Connecticut Caucasian students aged 9 through 18 years (N = 24,645). Our objectives were to estimate the prevalence of sun protection use and to evaluate the relationship between sun protection use and health-risk behaviors and attitudes about appearance. We present data from 1988 through 1995 from the Connecticut Health Check, a health risk appraisal survey sponsored by the Connecticut Department of Public Health. Students enrolled in public and private elementary junior as well as senior high schools took the self-administered anonymous survey, which included multiple-choice questions about use of sun protection, cigarettes, and alcohol and about body image and self-esteem. We report prevalence proportions for use of sun protection by demographic features. We compared the proportion of students in 3 categories of outcome (always, sometimes, and never use sun protection) who reported various health-risk behaviors. Twenty percent of the sample reported always using sun protection; this is well below national goals set forth in the Healthy People 2000 recommendations. Sun protection use was inversely related to age and was higher among girls than boys at all ages. At all ages, students who did not use sun protection were more likely than those who did to report other health risk behaviors, such as use of cigarettes and alcohol. The data suggested that use of sun protection is associated with positive attitudes about appearance and self-image. Use of sun protection may be one component of an overall mode of health awareness and behavior. Programs promoting safe sun practices should target boys and be integrated into an overall campaign aimed at other risk-taking behaviors.

A public health response to emerging technology: expansion of the Massachusetts newborn screening program

The development of a new technology, called tandem mass spectrometry (tandem MS), has challenged governments worldwide to consider expanding universal newborn screening for rare metabolic disorders. In 1997 the Massachusetts Department of Public Health developed a public process to meet this challenge. After addressing significant medical, legal, ethical, and logistical issues raised by tandem MS, Massachusetts incorporated one new disorder into the mandatory newborn screen and developed an optional pilot program for 20 additional disorders. The Massachusetts experience has wide relevance for other nations and states. As screening protocols are contemplated for entire populations-for newborns and others- it will remain essential that the public participate in an open process of reviewing the justification for and logistics of screening.

Cancer skills laboratories for medical students: a promising approach for cancer education

BACKGROUND

Most medical students graduate without the skills necessary to assist patients in cancer control. To address this problem, the authors developed a cancer skills laboratory for second-year medical students.

METHODS

The skills laboratory consists of two hours of training, with 15 minutes allotted per station (six to eight students assigned per station). Faculty and fellows lead the stations on prostate cancer, breast cancer, colorectal cancer, skin cancer, counseling for smoking cessation, and a discussion of anti-tobacco advertisements. Students completed pre- and post-laboratory surveys consisting of ten brief questions.

RESULTS

Overall, 94% of eligible students in 1997 and 1998 completed the surveys. Using a five-point scale, self-rated skill level increased from 2.12 to 3.83 when all modalities were averaged (p < .001).

CONCLUSIONS

Cancer skills laboratories are a promising new means for cancer education.

Genetically engineered transgenic plants with the domain 1 sequence of tobacco mosaic virus 126 kDa protein gene are completely resistant to viral infection

In many plant RNA viruses, Domains 1, 2 and 3 are conserved in replicase proteins. In order to examine the interference of viral replication by the Domain 1 sequence, we generated transgenic plants transformed with DNA corresponding to the Domain 1 sequence of the TMV 126 kDa protein. This DNA sequence includes the TMV RNA from nucleotides 1 to 2,149, which comprises both the 5'-untranslated and methyl transferase region. The transgenic plants obtained showed complete resistance to TMV infection. The presence of the Domain 1 sequence in the plants completely prevented local necrosis in Nicotiana tabacum cv. Xanthi nc, and any systemic development of symptoms in Nicotiana tabacum Xanthi upon TMV inoculation. Most transgenic plants sustained the conferred resistance even under TMV inoculum concentrations up to as high as 1,000 microg/ml. To detect any accumulation of TMV coat protein or viral RNA in infected transgenic plants, immunochemical tests and Northern blot analyses were carried out. Neither viral RNA or coat protein was detectable in the systemic leaves of the completely resistant transgenic plants, whereas they were accumulated in large quantities in all of the control plants. Because of the conservation of Domain 1 in many plant RNA viruses, the acquisition of resistance to virus infection using the Domain 1 sequence appears to be a very effective strategy for breeding of viral resistant plants.

Screening for malignant melanoma: A cost-effectiveness analysis

BACKGROUND

Skin cancer is the most common cancer in the United States. Increasing evidence suggests that screening for malignant melanoma is effective, but its cost-effectiveness has not been determined.

OBJECTIVE

We attempted to determine the effectiveness and costs of a visual screen to diagnose malignant melanoma in high-risk persons.

METHODS

We developed a decision analysis comparing no skin cancer screen with a single screen by a dermatologist. Clinical outcomes included malignant melanoma, nonmelanoma skin cancer, or no skin cancer. Life expectancy and costs of care were projected on the basis of clinical findings.

RESULTS

Skin cancer screening increased average discounted life expectancy from 15.0963 years to 15.0975 years. Based on the prevalence of malignant melanoma, however, this translates into an increased discounted life expectancy of 0.9231 years for each person with diagnosed melanoma. Using a cost of $30 per screen, total skin cancer-related costs for a cohort of 1 million people increased from $826 million with no screen to $861 million with screening, with an increase of 1200 years of life. This results in an incremental cost-effectiveness ratio of $29,170 per year of life saved (YLS) with screening. Sensitivity analysis showed that the cost-effectiveness ratio for screening remained below $50,000/YLS if the prevalence of melanoma in the screened population was at least 0. 0009, the probability that a melanoma detected in screening was localized was at least 94.8%, or the cost of each screen was below $57.

CONCLUSION

Skin cancer screening in high-risk patients is likely to be associated with a small increase in discounted life expectancy and is reasonably cost-effective compared with other cancer screening strategies.

Chemotherapy with etoposide, vincristine, doxorubicin, bolus cyclophosphamide, and oral prednisone in patients with refractory cutaneous T-cell lymphoma

BACKGROUND

This Phase II study was undertaken to assess the efficacy and toxicity of chemotherapy with etoposide, vincristine, doxorubicin, bolus cyclophosphamide, and oral prednisone (EPOCH regimen) in patients with advanced, refractory cutaneous T-cell lymphoma (CTCL).

METHODS

Fifteen patients were treated with a 96-hour continuous infusion of etoposide, vincristine, doxorubicin, bolus cyclophosphamide, and oral prednisone, followed by granulocyte-colony stimulating factor support and trimethoprim/sulfamethoxazole prophylaxis. The median age of the patients was 53 years (range, 17-82 years). Six patients had Sézary syndrome (SS), four patients had visceral involvement, and four patients had anaplastic large cell morphology, three with Ki-1 (CD30) positivity. All patients had disease that was refractory to prior chemotherapy or electron beam irradiation and eight of these patients had received cyclophosphamide, doxorubicin, vincristine, and prednisone. Seven patients had received prior interferon therapy and nine patients had received fludarabine and/or 2-CDA.

RESULTS

After a median of 5 cycles (range, 1-9 cycles), 4 patients achieved a complete response (27%) and 8 patients achieved a partial response (53%) for an overall response rate of 80% (95% confidence interval, 52-96%). Three patients with visceral involvement, two of three patients with anaplastic large cell morphology, and one patient with human T-cell lymphoma virus leukemia/lymphoma did not respond. All 12 responders had improvement in skin disease; 2 of 6 patients with SS had complete disappearance of circulating Sézary cells. The median progression free survival was 8.0 months (range, 3-22 months). After a median follow-up of 11.4 months (range, 2-56+ months), the median patient survival was 13.5 months. Grade 3 or 4 hematologic toxicity occurred in 8 patients (61%); 5 of these 8 patients had febrile neutropenia. Six patients developed staphylococcal bacteremia, two patients had disseminated herpes infection, and one patient had Pneumocystis carinii pneumonia. Grade 3 neurotoxicity occurred in one patient. Two patients had a significant decrease in left ventricular ejection fraction and one patient had supraventricular tachycardia.

CONCLUSIONS

EPOCH chemotherapy has a high response rate with acceptable toxicity in patients with advanced and refractory CTCL.

Public knowledge, awareness, and perceptions of the association between skin aging and smoking

BACKGROUND

Although the tobacco industry promotes images of glamour, 2 decades of epidemiologic research have concluded the opposite: smokers have enhanced facial aging and skin wrinkling compared with nonsmokers.

OBJECTIVE

The purpose of this study was to obtain information on the public's awareness of the association between cigarette smoking and skin aging.

METHODS

In the spring of 1994, the Maine-wide Cooperative Telephone Survey conducted telephone interviews in 678 randomly selected, nonseasonal dwelling units in Maine. From each dwelling unit, one randomly selected adult resident was interviewed to assess awareness of the association of skin aging with smoking.

RESULTS

Fifty-eight percent of those persons interviewed had smoked at least 100 cigarettes, and among them, 24% were current smokers (28% men, 21% women). After adjusting for sex, age, and education, current smokers remained less likely to be aware of this association compared with former (prevalence ratio, 0.78; 95% confidence interval, 0.64-0.95) and never smokers (prevalence ratio, 0.87; 95% confidence interval, 0.70-1.07). However, nearly one fourth of smokers in this study believed that most or some smokers would consider this information in their decision to quit, with slightly higher findings in young smokers.

CONCLUSION

These findings are of public health importance. While strategies for framing messages about the association between smoking and facial aging await further study, this association deserves to be considered in all tobacco control and counter-advertising campaigns.

The Falmouth Safe Skin Project: evaluation of a community program to promote sun protection in youth

A multidimensional community-based skin cancer prevention program was conducted in Falmouth, Massachusetts, combining community activism with publicity campaigns and behavioral interventions to improve sun protection knowledge; attitudes; and practices in parents, caregivers, and children. The program was associated with improvements in target outcomes, based on two telephone surveys of random samples of parents (n = 401, 404). After program implementation, fewer parents reported sunburning of their children, particularly among children 6 years old or younger (18.6% in 1994 vs. 3.2% in 1997), and more parents reported children using sunscreen, particularly continuous use at the beach (from 47.4% to 69.9% in younger children). Hat and shirt use did not increase. Improvements also were seen in parent role modeling of sun protection practices, parents' self-efficacy in protecting children from the sun, and sun protection knowledge. While these findings must be interpreted cautiously, they do suggest that this project was effective in promoting sun protection.

The New Moms Project: educating mothers about sun protection in newborn nurseries

Sun protection habits should begin early in life and be taught as part of routine preventive health care. Early teaching of parents aims to introduce an easily achieved means of sun protection with the goal of instilling these practices as habits in the parents and their young children. We developed a maternity nurse-led intervention for 187 mothers at newborn nurseries in Falmouth, Massachusetts, combining educational material and personal discussions. One year after the intervention we successfully contacted 73% of the mothers. Nearly 90% recalled the informational program and equal numbers stated that receiving educational materials in the newborn nursery was timely. Nearly two-thirds of mothers reported that this was the only sun protection information received from a provider in the past year.

Participant satisfaction and value in American Academy of Dermatology and American Cancer Society skin cancer screening programs in Massachusetts

BACKGROUND

More than 1 million Americans have attended the American Academy of Dermatology's Melanoma/Skin Cancer Screening Programs since 1985. However, there have been no reports of the participants' perceived value, satisfaction, and benefits of skin cancer screening.

OBJECTIVE

We attempted to measure the benefits and subsequent screening practices of persons with presumptive positive screening diagnoses.

METHODS

A self-administered questionnaire was sent to participants with positive screening diagnoses in Massachusetts.

RESULTS

Of the 643 respondents, 81% rated their satisfaction as high and 84% had similar ratings for the value of the screening. Screenings apparently led to an increase in self-screening (60% before screening compared with 84% after screening).

CONCLUSION

Although screening appears to have relatively strong benefits, further studies should be conducted nationally.

Medical students' knowledge, attitudes, skills, and practices of cancer prevention and detection

BACKGROUND

Surveys of U.S. physicians show deficiencies in cancer detection and counseling skills. Thus, there is a compelling need to provide skills teaching during medical school for cancers with preventable mortality and for counseling techniques for smoking prevention and cessation.

METHODS

In advance of the integration of initiatives for cancer education into the medical school curriculum, the authors conducted a baseline survey of students' knowledge, attitudes, skills, practices, observation, and training (KASPOT) related to cancer education. Eighty-one percent of Boston University School of Medicine students (n = 499) completed surveys.

RESULTS

The students reported higher levels of KASPOT for breast and cervical cancers, compared with skin cancer examination or tobacco use cessation or prevention counseling. More than half of third- and fourth-year students reported that too little emphasis was given to cancer control education.

CONCLUSIONS

It appears that students' practice and skills for detection of the most common cancer (skin cancer), and for cancers with the greatest mortality (tobacco-related cancers) are deficient. Revisions in medical students' curricula should seek to address these shortcomings.

Evaluation: methods and strategy for evaluation--Massachusetts

Various challenges exist when evaluating statewide, community-based public health initiatives and these need to be addressed by tobacco control programs. There are factors inherent in public health initiatives that can make it difficult to assess causality and effectiveness. These include initial design elements, funding mandates, duration of program and resources allocated for evaluation. In addition, outside efforts to undermine the initiative also must be taken into consideration, when evaluating effectiveness. This article focuses on these and other challenges encountered by the Massachusetts Tobacco Control Program and presents information on the state specific tobacco surveys conducted for the Program.

Multiple cerebellar infarction due to vertebral artery obstruction and bulbar symptoms associated with vertical subluxation and atlanto-occipital subluxation in ankylosing spondylitis

Ankylosing spondylitis (AS) results in disease-specific inflammation at the site of ligamentous insertion into the bone. Atlantoaxial joint subluxation and vertical subluxation of the axis may occur as a consequence of instability resulting from the inflammatory process. Spontaneous anterior atlantoaxial subluxation is a well recognized complication in about 2% of patients with AS, and presents with or without signs of spinal cord compression. Vertical subluxation may follow anterior or posterior subluxation. It was noted in 3-8% of patients with rheumatoid arthritis, but is an exceedingly rare complication of AS. Moreover, it has never been reported that multiple cerebellar infarction and bulbar symptoms developed spontaneously due to atlanto-occipital subluxation and vertical subluxation in a patient with a long [corrected] history of AS. We describe a man with AS who developed multiple cerebellar infarction due to vertebral artery obstruction and bulbar symptoms associated with atlanto-occipital subluxation and vertical subluxation.

Coexistence of coronary aneurysms and total occlusion of coronary arteries in systemic lupus erythematosus

A 22-year-old woman with known SLE and chronic hepatitis B developed anginal pain. During this period there was serologic but no other clinical evidence of active SLE. Myocardial perfusion SPECT showed a severe reversible perfusion defect in the posterior wall, and coronary angiography revealed multiple coronary aneurysms in the left anterior descending artery and circumflex artery and total occlusion of the proximal right coronary artery. This case suggests that coronary aneurysms and total occlusion may represent a sequela of arteritis, or of a combination of underlying vasculitis and a recent thrombotic obstruction due to antiphospholipid syndrome.

Early detection of cutaneous lymphoma

Cutaneous lymphomas comprise a spectrum of diseases characterized by infiltration of the skin by malignant lymphocytes. The clinical manifestations of cutaneous lymphomas vary, and they can mimic benign dermatoses, as well as nodal or visceral malignancies with cutaneous spread. Cutaneous lymphomas are divided into T-cell lymphomas and B-cell lymphomas. Cutaneous T-cell lymphomas include mycosis fungoides, Sézary syndrome, lymphomatoid papulosis, CD30+ large cell lymphoma, and adult T-cell leukemia/lymphoma. The extent and severity of skin manifestations in cutaneous T-cell lymphomas are prognostic indicators of extracutaneous involvement. Primary cutaneous B-cell lymphomas comprise 10% to 25% of all primary cutaneous non-Hodgkin's lymphomas and are classified according to their cell of origin. Most cutaneous B-cell lymphomas have an indolent course and excellent prognosis when compared to their nodal counterparts. Many factors have been implicated in the etiology of cutaneous lymphomas, including chemical and drug exposures, as well as microbial agents, such as the Epstein-Barr virus (EBV), human T-lymphocyte virus-1 (HTLV-1), and Borrelia burgdorferi. Immunohistochemistry and lymphocyte-receptor gene rearrangement studies are useful in distinguishing malignant from benign conditions.

Public health interventions for melanoma. Prevention, early detection, and education

Worldwide melanoma control programs that include some combination of primary prevention, education, and screening activities have only recently begun to undergo an evaluation process. More studies with rigorous design and evaluation are needed. Until then, the proper public health policy guidelines for melanoma control, especially screening, are open to debate. Future studies must determine how screening, early detection, case finding, and education can best be used to reduce mortality and achieve optimal melanoma control.

Factors associated with smoking among children and adolescents in Connecticut

INTRODUCTION

The age of smoking initiation has dropped over the past four decades. Since behaviors and attitudes adopted in late childhood or early adolescence predict future smoking, it is important to understand the smoking and other risk-taking behaviors and attitudes of children aged 12 and younger. The goal of the analyses presented here was to describe behavioral and attitudinal factors associated with smoking among elementary school (grades 4-6), middle school (grade 7-8), and high school (grades 9-12) students in Connecticut.

METHODS

We have used data from 8 years (1988-1996) of an anonymous, self-administered health risk appraisal survey given to children and adolescents in self-selected public and private schools. We compared the proportion of smokers and nonsmokers who reported various behaviors and attitudes and compared them with the chi-square test.

RESULTS

Fifteen percent (n = 4,884) of the total population (n = 31, 861) were current smokers. At all grade levels, current smokers were more likely than nonsmokers to engage in risk-taking behaviors, and to report more stress and depression. Indicators of risk-taking and stress were also associated with the intent to smoke among children in grades 4-6.

CONCLUSIONS

Smoking occurs within the context of other risk-taking behavior and psychological distress, among both children and older adolescents. Our data provide support for the idea of early identification and targeting of children at high risk of smoking in elementary school, possibly as early as grade four.

Do pediatricians counsel families about sun protection?: a Massachusetts survey

BACKGROUND

Pediatric visits during summer months may be especially opportune times for sun protection counseling for children and their parents. Few data exist on the extent of such counseling.

OBJECTIVE

To begin to assess this, we surveyed practicing Massachusetts pediatricians to examine current attitudes and practices of sun protection counseling.

DESIGN AND SETTING

Surveys mailed to Massachusetts pediatricians.

RESULTS

We received surveys from 756 (60%) of 1263 eligible Massachusetts pediatricians. Almost 70% indicated that they recommended safe sun practices to more than 50% of their patients and their parents during the summer months. Counseling regarding seat belt use, bicycle helmet use, and smoking prevention were ranked higher in priority than sun protection counseling by pediatricians; nutritional guidelines were noted by pediatricians to be a parent's most frequent concern. Four variables were independently associated with a practitioner's providing safe sun recommendations to more than 50% of parents and children: (1) private setting and health maintenance organization practitioners as opposed to academic physicians, (2) high ranking of patients' safe sun knowledge, (3) high priorities of both parents and physicians for sun protection counseling and parental knowledge of safe sun practices relative to other recommendations, and (4) pediatrician interest in receiving instructional materials.

CONCLUSIONS

For the most part, summer sun protection counseling among Massachusetts pediatricians seems well integrated into standard practice. Most pediatricians rated their confidence level as high for discussing sun protection and only a few cited inadequate training or poor reimbursement as barriers toward improved counseling. Small steps, such as providing more instructional materials to patients and using office-based reminder systems, may improve the quality of sun protection counseling practices. Incorporating sunburn prevention into the list of routinely recommended injury prevention guidelines for pediatricians should be considered.

Evaluation of the Ultraviolet Index: media reactions and public response

BACKGROUND

In response to the increasing rate of skin cancer, particularly melanoma in the United States, the Environmental Protection Agency, the National Weather Service, the Centers for Disease Control and Prevention, National Association of Physicians for the Environment, and the American Academy of Dermatology, developed the Ultraviolet Index (UVI) to inform the public of the strength of the sun's rays and advise on methods for sun protection.

OBJECTIVE

Our purpose was to evaluate the extent to which television stations and newspapers reported the UVI and assess the public's response to it.

METHODS

To evaluate the effect of this effort, we surveyed television weather forecasters at 185 stations and examined weather pages in 54 newspapers in 58 cities that received the UVI reports. We also conducted a population probability telephone survey of 700 white adults (18 years of age and older) in these 58 cities.

RESULTS

Seventy-one percent of the 169 stations that provided survey data for both 1994 and 1995 broadcast the UVI; 61% of newspapers reported the UVI. Nearly 64% of the 700 respondents (n = 445) had heard of the UVI. Of these respondents, 38% (n = 170) stated that they or their family changed their sun protection practices as a result of the UVI.

CONCLUSION

The majority of television weather forecasters and newspapers reported the UVI. Most of the public was aware of the UVI, causing some to change sun protection practices. Further evaluation is required to maximize the effect of the UVI on sun protection practices.

Sun protection behaviors of the U.S. white population

BACKGROUND

Sun protection behaviors are recommended to prevent skin cancer, which has increased in incidence. This study measured the prevalence of sun protection behaviors and determined personal characteristics associated with them.

METHODS

Data from 10,048 white respondents to the 1992 National Health Interview Survey Cancer Control Supplement were analyzed. Multiple logistic regression models were constructed to relate personal characteristics to specific behaviors.

RESULTS

Fifty-three percent of respondents reported they were "very likely" to use sunscreen, wear protective clothing, or seek shade if they were outside on a sunny day for more than 1 hr. Proportions for the individual behaviors were 32, 28, and 30%, respectively. Compared with people who do not burn, those reporting severe sunburn after 1 hr of sun exposure reported more use of sunscreens (odds ratio [OR] = 2.4, 95% confidence interval [CI] 2.0, 2.9), shade (OR = 1.8, 95% CI 1.5, 2.1), and protective clothing (OR = 2.2, 95% CI 1.9, 2.7). Other factors associated with practicing protection behaviors included a personal history of skin cancer, older age, and female sex.

CONCLUSIONS

A large percentage of white U.S. adults did not protect themselves from sun exposure. Additional education of the general public and persons at higher risk for skin cancer is needed.

Sunbathing habits and sunscreen use among white adults: results of a national survey

OBJECTIVES

This study assessed current levels of sunbathing and sunscreen use in the United States.

METHODS

From a general-population telephone survey of aquatic activities among adults in 3042 US households, we examined responses by the 2459 Whites.

RESULTS

Most adults (59%) reported sunbathing during the past year, and 25% reported frequent sunbathing. Of the subsample who reported sunbathing during the month before the interview, 47% routinely used sunscreen. Of these individuals, almost half did not use sunscreens with a solar protection factor of 15 or higher.

CONCLUSIONS

About a quarter of US White adults report frequent sunbathing, and only about a quarter of sunbathers use sunscreens at recommended levels. These results should help focus future sun protection educational efforts.

Adjuvant therapy for cutaneous malignant melanoma

We discuss the current status of adjuvant therapy for melanoma by first reviewing the rationale and goals of adjuvant therapy and then analyzing the results of published randomized trials. We pay particular attention to adjuvant interferon trials that raise many challenging issues in the management of patients with melanoma at high risk of recurrence. Past adjuvant trials have used immunotherapeutic approaches, chemotherapy, radiation therapy, as well as hormonal and retinoid therapy. We also summarize ongoing adjuvant trials.

Is it lymphoma or lymphomatoid papulosis?

Distinguishing malignancy from premalignant conditions can be difficult. Controversy surrounds both the clinical and histologic criteria used to distinguish lymphomatoid papulosis, a benign disorder, from CD30+ anaplastic large-cell lymphoma. Three case histories illustrate important points in categorizing different lymphoproliferative disorders as benign or malignant. We emphasize a multidisciplinary approach to improve diagnosis and patient management.

Proceedings of the International Consensus Conference on Cutaneous T-cell Lymphoma (CTCL) Treatment Recommendations. Boston, Massachusetts, Oct. 1 and 2, 1994

At the International Consensus Conference for Cutaneous T-Cell Lymphoma (CTCL) Treatment Recommendations (held in Boston, Massachusetts, Oct. 1 and 2, 1994), international experts were asked to assess where consensus existed and to identify areas that required clinical research. We review the epidemiology, pathology, and immunology of CTCL, summarize the important areas in which consensus exists, and discuss newer targeted therapies.

Full proceedings from the National Conference to Develop a National Skin Cancer Agenda. American Academy of Dermatology and Centers for Disease Control and Prevention, Washington, D.C., April 8-10, 1995

National efforts to reduce skin cancer incidence and mortality require scientifically coordinated efforts. This report summarizes the first American Academy of Dermatology/Centers for Disease Control and Prevention national conference to develop a skin cancer agenda. Leading experts in dermatology, public health, medicine, health education, nursing, behavioral sciences, environmental health and epidemiology identified and prioritized skin cancer control issues in five key areas. Discussion centered around strategies for reducing UV exposure and increasing public and professional awareness of skin cancer. Panelists in five sessions developed consensus on several public and professional recommendations and a series of research strategies.

An analysis of the successful 1992 Massachusetts tobacco tax initiative

In November 1992, voters in Massachusetts (United States) passed a statewide tax initiative adding an extra 25 cents to the price of a pack of cigarettes. The Massachusetts Coalition for a Healthy Future, led by volunteers from the Massachusetts Division of the American Cancer Society, achieved this victory, despite a public anti-tax mood and $7.3 million spent by the tobacco industry. The tax has since generated millions of dollars for tobacco education and control programmes, leading to acceleration of the decline of tobacco consumption in the state. An analysis of the passage of this initiative should help other states considering this approach to tobacco control.

Melanoma awareness and self-examination practices: results of a United States survey

BACKGROUND

Skin cancers are common and there has been a dramatic increase in their incidence, particularly melanoma. However, little is known about awareness of melanoma and early detection practices in the general U.S. population.

OBJECTIVE

In 1995, the American Academy of Dermatology increased their efforts to promote awareness of melanoma. This study was conducted to document current knowledge of melanoma and self-examination practices.

METHODS

In February 1995, a telephone survey was conducted in a nationally representative sample of 1001 persons at least 18 years of age (3% margin of error) that included questions on knowledge, attitudes, and practices regarding early detection of melanoma.

RESULTS

Almost 42% of those surveyed were unaware of melanoma, and only 26% of those who were aware could identify its specific signs. Most recognized at least one common risk factor for melanoma (e.g., sun exposure, fair skin). However, many did not distinguish melanoma from other skin cancers in terms of risk factors, signs of early disease, and body site distribution. The lowest measures of melanoma knowledge and attitudes were found among those who are male, nonwhite, and parents, and those with the lowest level of education and income. More than half (54%) did not conduct a self-examination. This practice was most frequently reported by women, white persons, and the elderly, as well as those with a greater knowledge of melanoma.

CONCLUSION

Our research documents deficiencies in knowledge and practices related to early detection of melanoma in the general U.S. population and supports the need for public education about melanoma.

Evaluation of the American Academy of Dermatology's National Skin Cancer Early Detection and Screening Program

BACKGROUND

Increasing incidence and mortality rates from cutaneous melanoma are a major public health concern. As part of a national effort to enhance early detection of melanoma/skin cancer, the American Academy of Dermatology (AAD) has sponsored an annual education and early detection program that couples provision of skin cancer information to the general public with almost 750,000 free skin cancer examinations (1985-1994).

OBJECTIVE

To begin to evaluate the impact of this effort, we determined the final pathology diagnosis of persons attending the 1992-1994 programs who had a suspected melanoma at the time of examination.

METHODS

We directly contacted all such persons by telephone or mail and received pathology reports from those who had a subsequent biopsy.

RESULTS

We contacted 96% of the 4458 persons with such lesions among the 282,555 screenings in the 1992-1994 programs. We obtained a final diagnosis for 72%, and the positive predictive value for melanoma was 17%. Three hundred seventy-one melanomas were found in 364 persons. More than 98% had localized disease. More than 90% of the confirmed melanomas with known histology were in situ or "thin" lesions (< or = 1.50 mm thick). The median thickness of all melanomas was 0.30 mm. The 8.3% of AAD cases with advanced melanoma (metastatic disease, regional disease, or lesions > or = 1.51 mm) is a lower proportion than that reported by the 1990 Surveillance, Epidemiology and End Result Registry. The rate of thickest lesions (> or = 4 mm) and late-stage melanomas among all participants was 2.83 per 100,000 population. Of persons with a confirmed melanoma, 39% indicated (before their examination) that without the free program, they would not have considered having a physician examine their skin.

CONCLUSION

The 1992-1994 free AAD programs disseminated broad skin cancer educational messages, enabled thousands to obtain a free expert skin cancer examination, and found mostly thin, localized stage 1 melanomas (usually associated with a high projected 5-year survival rate). Because biases impose possible limitations, future studies with long-term follow-up and formal control groups should determine the impact of early detection programs on melanoma mortality.

Cutaneous melanoma mortality among the socioeconomically disadvantaged in Massachusetts

OBJECTIVES

To identify groups for melanoma prevention and early detection programs, this study explored the hypothesis that survival with cutaneous melanoma is disproportionately lower for persons of lower socioeconomic status.

METHODS

Massachusetts Cancer Registry and Registry of Vital Records and Statistics data (1982 through 1987) on 3288 incident cases and 1023 deaths from cutaneous melanoma were analyzed. Mortality/incidence ratios were calculated and compared, predictors of late stage disease were examined with logistic regression analysis, and a proportional hazards regression analysis that used death registration as the outcome measure for incident cases was performed.

RESULTS

Lower socioeconomic status was associated with a higher mortality/incidence ratio after adjustment for age and sex. For education, the mortality/incidence ratio was 0.37 in the lower group vs 0.25 in the higher group (rate ratio = 1.48, 95% confidence interval [CI] = 1.08, 2.03). Late stage disease was independently associated with lower income (rate ratio for lowest vs highest tertile = 1.64, 95% CI = 1.20, 2.25), and melanoma mortality among case patients was associated with lower education (rate ratio = 1.52, 95% CI = 1.09, 213).

CONCLUSIONS

Melanoma patients of lower socioeconomic status may be more likely to die from their melanoma than patients of higher socioeconomic status. Low- SES communities may be appropriate intervention targets.

Preventive strategies and research for ultraviolet-associated cancer

Ultraviolet (UV)-associated cancer is the most common cancer in the United States. Approximately 90% of nonmelanoma skin cancer and 65% of melanoma are attributable to UV exposure and theoretically could be eliminated by primary prevention measures. Safe sun strategy includes use of sunscreens, use of protective clothing, minimization of exposure from 10 A.M. to 3 P.M., and avoidance of tanning parlors. Although more definitive data in human populations on the effectiveness of sunscreens to prevent melanoma and skin cancer are needed, sunscreens are thought to reduce risk. Safe sun prevention must start in childhood and adolescence when people receive most of their UV exposure. Secondary prevention through professional and public education and early detection may further reduce melanoma mortality.

Assessing clinical outcomes in cutaneous T-cell lymphoma

It is apparent that multiple end points are required to adequately describe the response to therapy for CTCL. Investigators may differ as to which end points are best suited for their data. In general, multiple end points provide a better overall view of response to treatment as compared with a single end point. Regardless, measures of response and end points should be clearly defined and the methods of calculating end points clearly stated.

Melanoma and Skin Cancer Control: An International Perspective

Approximately one million Americans are diagnosed with skin cancer each year. Since melanoma and skin cancer are amenable to prevention, education, and early detection, efforts to reduce the incidence of and death from melanoma have developed in many countries. Programs promoting behavioral changes and the incorporation of skin cancer control into national health care agendas have begun in a number of countries. Additional programs for the at-risk and general populations require further development and evaluation.

Epidemiology and clinical manifestations of cutaneous T-cell lymphoma

Cutaneous T-cell lymphoma (CTCL) encompasses a constellation of diseases of malignant clonal T lymphocytes that present initially in the skin. Within this disease spectrum, mycosis fungoides, and the Sézary syndrome are best known. Progress in the understanding of the T-cell malignancies now places other clinical entities within this disease classification. The authors review the epidemiology and clinical manifestations of CTCL.

The current status of melanoma early detection and screening

Multiple strategies are required to combat the increasing incidence and mortality of cutaneous melanoma. Major questions about melanoma and skin cancer are reviewed, with particular attention to education and early detection.

The early detection of and screening for melanoma. International status

Cutaneous melanoma is an increasingly common public health problem in industrialized nations. In theory, education and early detection should decrease melanoma morbidity and mortality, because the lesion is external and visible, risk factors are known, and thin tumors are associated with a high 5-year survival rate. The efficacy of early detection and screening programs, however, remains untested by randomized trials. Some early data are available from melanoma prevention and control efforts that have begun in many nations over the past decade. Textbook definitions of cancer screening are particularly challenging when applied to skin cancer control. Although some propose that there are rigid differences among screening, education, and early detection of skin cancer, the visible nature of this cancer makes early detection through education and screening inextricably intertwined. This article discusses the intermediate measures of education and screening within the context of the American Academy of Dermatology programs. Over the next few decades, screening and education for melanoma and other skin cancer will receive increasing worldwide attention. Multiple strategies will be required to combat increasing incidence and mortality rates. Screening and educational programs have been implemented worldwide, but data on their effects are only just being collected. Future collaborative work in melanoma/skin cancer prevention, education, and early detection holds promise as a way to decrease mortality and save lives.
