Ultraviolet radiation and skin cancer.

Abstract: Skin cancer is the most common type of cancer in fair-skinned populations in many parts of the world. The incidence, morbidity and mortality rates of skin cancers are increasing and, therefore, pose a significant public health concern. Ultraviolet radiation (UVR) is the major etiologic agent in the development of skin cancers. UVR causes DNA damage and genetic mutations, which subsequently lead to skin cancer. A clearer understanding of UVR is crucial in the prevention of skin cancer. This article reviews UVR, its damaging effects on the skin and its relationship to UV immunosuppression and skin cancer. Several factors influence the amount of UVR reaching the earth's surface, including ozone depletion, UV light elevation, latitude, altitude, and weather conditions. The current treatment modalities utilizing UVR (i.e. phototherapy) can also predispose to skin cancers. Unnecessary exposure to the sun and artificial UVR (tanning lamps) are important personal attributable risks. This article aims to provide a comprehensive overview of skin cancer with an emphasis on carefully evaluated statistics, the epidemiology of UVR-induced skin cancers, incidence rates, risk factors, and preventative behaviors & strategies, including personal behavioral modifications and public educational initiatives.

The Matthew Effect in science.

Abstract: Based on interviews with Nobel laureates, Merton^ observes that eminent scientists get disproportionately great credit for their contributions to science, while relatively unknown scientists tend to get disproportionately little credit for comparable contributions. Merton also proposes and supports the related hypothesis that a scientific contribution will have a greater visibility in the community of scientists when it is introduced by a scientist of high rank than when it is introduced by one who has not yet made his mark. This raises interesting implications as to the beneficial effect of having an established scientist put his or her name on a paper to get better visibility for junior coworkers. One side effect of the acclamation and acceptance given to proven and great scientists is the fact that centers of demonstrated scientific excellence are allocated far larger resources for research than centers that have yet to make their mark.

Pyoderma gangrenosum: clinicopathologic correlation and proposed diagnostic criteria.

Abstract: Pyoderma gangrenosum is a rare but significant cause of ulcerations. It is a diagnosis of exclusion. Herein, we suggest diagnostic criteria and some historical perspectives on the diagnosis of pyoderma gangrenosum.

A comparison of current acne grading systems and proposal of a novel system

Abstract: 416 Systematic assessment of the severity of acne vulgaris continues to challenge the clinician. Acne is a pleomorphic disorder of variable course and anatomical distribution. For these reasons, no system has been accepted universally. An ideal grading system would (i) be accurate and reproducible, (ii) be simple to use by the clinician over serial office visits, (iii) eliminate the tediousness of lesion counting and the expense of photography, and (iv) reflect subjective criteria, i.e. psychosocial factors. Several research studies attempting to quantify the psychopathologic effect of acne have yielded iticotisistent results.' Until a more reliable quantitative psychometric instrument is developed, the psychosocial impact of acne must be documented elsewhere in the patient's record.
