Black Americans clearly bear a greater burden from head and neck cancer. The underlying causes are largely unknown, but are most likely due to a complex interplay of differences in access to health care, quality of medical care, biologic/genetic factors, incidence of comorbid conditions, exposure to carcinogens, diet, and cultural beliefs. Prospective studies are needed to define the relative importance of these factors and to inform intervention strategies.

Main Outcome Measures: Age-adjusted melanoma incidence and stage at diagnosis. Results: Of 41 072 cases of melanoma, 39 670 cases were reported for white non-Hispanics (WNHs), 1148 for white Hispanics (WHs), and 254 for blacks. Melanoma incidence rates increased by 3.0% per year among WNH men (PϽ .001), 3.6% among WNH women (PϽ .001), 3.4% among WH women (P = .01), and 0.9% among WH men (P =.52), while remaining relatively stable among black men and women. Both WHs and blacks had significantly more advanced melanoma at presentation: 18% of WH and 26% of black patients had either regional or distant-stage melanoma at diagnosis compared with 12% of WNH patients. The proportion of distant-stage melanoma diagnosed among WHs and blacks changed little from 1990 to 2004, compared with a steady decrease in the percentage of melanoma cases diagnosed at distant stage among WNHs (PϽ .001). Such differences in the time trends of the proportion of distant-stage melanoma remained after excluding in situ cases. Conclusions: The rising melanoma incidence among WNHs and WHs emphasizes the need for primary prevention. The persistence of disparity in melanoma stage at diagnosis among WHs, blacks, and WNHs warrants closer examination of secondary prevention efforts in minority groups.

BackgroundRecombinant human growth hormone (r-hGH) is used to treat: growth hormone deficiency in children and adults; children born small for gestational age; Turner's syndrome; and chronic renal failure. r-hGH is administered by daily subcutaneous injection and may be given using a number of different administration devices. The aim of this survey was, firstly, to identify which attributes of an r-hGH administration device are considered most important to physicians, teenage patients, parents of young children requiring GH and nurses who have experience of r-hGH administration, and, secondly, to determine how they rate existing devices in each of these key attributes.MethodsThe opinions of 67 individuals with experience in r-hGH administration were captured in discussion sessions. Parents, physicians and nurses were asked to rate 19 device attributes by completing a questionnaire, and to rank four different r-hGH administration devices (including a conceptual electronic device) in order of preference.ResultsReliability, ease of use, lack of pain during injection, safety in use, storage, and number of steps in preparation before use, during use and after were considered to be the five most desirable attributes of an r-hGH administration device. An electronic device was preferred to an automatic, multi-dose injection device, a needle-free injection device or a manual, ready-to-use, disposable injection device.ConclusionIn the opinion of physicians, nurses and parents using r-hGH injection devices, an ideal device must combine reliability with simplicity, while delivering treatment with minimal pain. An electronic device, which combines many of the most useful features of existing devices with novel functions, was the preferred option for r-hGH administration.

ObjectiveThe public health burden of tobacco-associated diseases in the USA remains high, in part because many people's attempts to quit are unsuccessful. This study examined factors associated with having lifetime or recent attempts to quit smoking among current smokers, based on a telephone survey of Florida adults.MethodsData from the 2007 telephone-based Florida Behavioral Risk Factor Surveillance System (BRFSS) and its follow-up survey, the Tobacco Callback Survey, were used to assess determinants of having ever attempted to quit smoking and attempted to quit smoking in the past 12 months. All analyses were conducted using SAS.ResultsAmong 3,560 current smokers, 41.5% reported having tried to quit smoking in the past 12 months while 83.4% reported having ever tried to quit. Having a history of a tobacco-related medical condition was significantly associated with both recent (Adjusted Odds Ratio (AOR) 1.41 [Confidence Interval 1.19–1.65]) and lifetime quit attempts (AOR 1.43 [1.15–1.79]). Greater nicotine dependence and being advised by a physician to quit smoking were also positively associated with lifetime quit attempts.Receipt of healthcare provider advice to quit smoking in the past 12 months and a strong belief that quitting following a long history of regular smoking would not result in health benefits and belief that there are health benefits to quitting smoking were associated with lifetime quit attempts.ConclusionTargeted smoking cessation interventions are needed for smokers with selected medical conditions and with high nicotine dependence. The importance of physician advice in encouraging individuals to quit is further highlighted.

Childhood exposure to ultraviolet radiation from the sun and a history of sunburns are risk factors for skin cancer. Because children spend time outdoors when they are at school, school sun protection policies are an important health issue, particularly in areas of the country with year-round warm and sunny climates, such as Florida. To better understand the sun protection policies and practices in South Florida schools, a sample (n = 51) of elementary and middle schools in Miami-Dade County public schools were surveyed as part of a CDC-funded cancer control program at the University of Miami. Of the principals and teachers surveyed, most (78%) knew about the county school system's guidelines for avoiding excessive heat exposure, which include two sun protection measures. Two-thirds reported that they shared these guidelines with teachers; 21% shared them with parents. Few schools monitor implementation of the guidelines, although 70% schedule outdoor activities to avoid peak sun hours. No schools required sunscreen, hats, or protective clothing. Physical education teachers and students spend an average of 4.5 and 0.6 hours per day outdoors, respectively. Improved school sun protection policies and monitoring of such policies is needed to reduce sun exposure and skin cancer risk for both students and staff.
