The annual incidence rate for melanoma and nonmelanoma skin cancer continues to rise and morbidity and deaths from skin cancer are increasing. Despite advances in therapeutics, the factors that most impact prognosis remain early recognition and removal of neoplasms before deep invasion or metastatic disease can occur. There are numerous public health and screening initiatives that have been introduced to help recognize disease earlier and to increase patients' awareness of signs or changes of lesions that may represent skin cancers...

INTRODUCTION: Occurring from ultraviolet radiation combined with impairing ozone levels, uncritical sun exposure and use of tanning beds an increasing number of people are affected by different types of skin cancer. But preventive interventions like skin cancer screening are still missing the evidence for effectiveness and therefore are criticised. Fundamental for an appropriate course of action is to approach the defined parameters as measures for effectiveness critically. A prerequisite should be the critical application of used parameter that are defined as measures for effectiveness...

BACKGROUND: In July 2008, the German statutory health insurance introduced a nationwide skin cancer screening program. Before the introduction, eligible physicians had to qualify to perform the screening test and counsel their patients on skin cancer screening. To educate physicians, a curriculum and training materials were developed. Since 2015 a revised curriculum and training materials have been used. The purpose of this paper is to provide information about the curriculum and to evaluate the revised training program...

Importance: Protective effects of UV-B radiation against nonmelanoma skin cancer (NMSC) are exerted via signaling mechanisms involving the vitamin D receptor (VDR). Recent studies have examined single-nucleotide polymorphisms (SNPs) in the VDR, resulting in contradictory findings as to whether these polymorphisms increase a person's risk for NMSC. Objective: To examine whether the polymorphisms in the VDR gene are associated with the development of NMSC and the demographic characteristics of the participants...

INTRODUCTION: Chronic mental health problems often emerge in young adulthood, when adults begin to develop lifelong health behaviors and access preventive health services. The associations between mental health problems and modifiable cancer risk factors in young adulthood are not well understood. METHODS: In 2016, the authors analyzed 2014 Behavioral Risk Factor Surveillance System data on demographic characteristics, health service access and use, health status, and cancer risk factors (tobacco use, alcohol use, overweight or obesity, physical activity, and sleep) for 90,821 young adults aged 18-39 years with mental health problems (depressive disorder or frequent mental distress) compared to other young adults...

Alkaptonuria is a rare autosomal recessive metabolic disorder caused by deficiency of homogentisic acid (HGA) oxidase, the only enzyme capable of catabolizing HGA. Deficiency of this enzyme leads to excess HGA which deposits in the connective tissue. We present a case of a 64-year-old woman who was referred to the dermatology clinic for a full body mole check and skin cancer screening. Clinically she had blue/gray pigmentation of the external ear and sclera. Also she had a domed papule on the left cheek with punctate gray pigmentation which was biopsied...

Melanoma is usually apparent on the skin and readily detected by trained medical providers using a routine total body skin examination, yet this malignancy is responsible for the majority of skin cancer-related deaths. Currently, there is no national consensus on skin cancer screening in the USA, but dermatologists and primary care providers are routinely confronted with making the decision about when to recommend total body skin examinations and at what interval. The objectives of this paper are: to propose rational, risk-based, data-driven guidelines commensurate with the US Preventive Services Task Force screening guidelines for other disorders; to compare our proposed guidelines to recommendations made by other national and international organizations; and to review the US Preventive Services Task Force's 2016 Draft Recommendation Statement on skin cancer screening...

Despite the highly preventable nature of skin cancer, it remains the most commonly diagnosed form of cancer in the United States. Recommendations for a complete skin cancer prevention regimen include engaging in photoprotection (e.g., sunscreen use), avoiding skin cancer risk behaviors (e.g., tanning), and receiving total body skin exams from a health care provider. The current study examined reported engagement in these behaviors among participants attending a community skin cancer screening (N = 319) in a high-risk catchment area to assess the need for increased health education on skin cancer prevention...

Skin cancer, which includes melanoma and squamous cell carcinoma, represents the most common type of cutaneous malignancy worldwide, and its incidence is expected to rise in the near future. This condition derives from acquired genetic dysregulation of signaling pathways involved in the proliferation and apoptosis of skin cells. The development of animal models has allowed a better understanding of these pathomechanisms, with the possibility of carrying out toxicological screening and drug development. In particular, the zebrafish (Danio rerio) has been established as one of the most important model organisms for cancer research...

Erectile dysfunction (ED) is a worldwide commonly reported condition; epidemiological data showed a prevalence ranging from 2.3 to 53.4% within different population subsets. In this context, the advent of phosphodiesterase type 5 inhibitors (PDE5is) in the second mid of 1990s has deeply changed the treatment scenario of this bothersome condition. Being user-friendly compounds with an excellent overall safety profile, PDE5is emerged as the first-line treatment for ED, thus overcoming topical alprostadil and intracavernous injections (ICIs)...

About 132 thousand cases of melanoma (more severe type of skin cancer) were registered in 2014 according to the world health organization. This type of cancer significantly affects the quality of life of individuals. Caffeine has shown potential inhibitory effect against epithelial cancer. In this study, it was proposed to obtain new caffeine-based molecules with potential epithelial anticancer activity. For this, a training set of 21 molecules was used for pharmacophore perception procedures. Multiple linear regression analyses were used to propose mono-, bi-, tri-, and tetra-parametric models applied in the prediction of the activity...

Early detection is considered to improve the prognosis of cutaneous melanoma. The value of population-based screening for melanoma, however, is still controversial. The aim of this study was to evaluate the predictive power of established risk factors in the setting of a population-based screening and to provide empirical evidence for potential risk stratifications. We reanalyzed data (including age, sex, risk factors, and screening results) of 354 635 participants in the Skin Cancer Research to provide Evidence for Effectiveness of Screening in Northern Germany project conducted in the German state of Schleswig-Holstein (2003-2004)...

A primary role of melanin in skin is the prevention of UV-induced nuclear DNA damage to human skin cells, where it serves to screen out harmful UV radiation. Melanin is delivered to keratinocytes in the skin after being excreted as melanosomes from melanocytes. Defects in melanin production in humans can cause diseases, many of which currently lack effective treatments due to their genetic origins (e.g., skin cancer, vitiligo, and albinism). The widespread prevalence of melanin-related diseases and an increasing interest in the performance of various polymeric materials related to melanin necessitates novel synthetic routes for preparing melanin-like materials...
