Total body skin examination for skin cancer screening among U.S. adults from 2000 to 2010.

OBJECTIVE: Melanoma incidence and mortality are increasing among United States adults. At present, routine skin cancer screening via total body skin examinations (TBSEs) by a physician is not recommended by the United States Preventive Services Task Force (USPSTF); while organizations such as the American Cancer Society recommend screening. Currently, there are limited data on the prevalence, correlates, and trends of TBSE among United States adults. METHODS: We analyzed data by race/ethnicity, age, and skin cancer risk level, among other characteristics from three different National Health Interview Survey (NHIS) cancer control supplements conducted every five years since 2000 in random United States households. High-risk status and middle-risk status were defined based on the USPSTF criteria (age, race, sunburn, and family history). RESULTS: Prevalence of having at least one TBSE increased from 14.5 in 2000 to 16.5 in 2005 to 19.8 in 2010 (P<0.0001). In 2010, screening rates were higher among the elderly, the fair-skinned, those reporting sunburn(s), and individuals with a family history of skin cancer. Approximately 104.7million (51.1%) U.S. adults are at high-risk for developing melanoma, of which 24.0% had at least one TBSE. CONCLUSIONS: TBSE rates have been increasing since 2000 both overall and among higher-risk groups. Data on screening trends could help tailor future prevention strategies.

Necrotizing Fasciitis of the Abdominal Wall Caused by Serratia Marcescens.

In this article, we present the first case of necrotizing fasciitis affecting the abdominal wall caused by Serratia marcescens and share results of a focused review of S. marcescens induced necrotizing fasciitis. Our patient underwent aorto-femoral bypass grafting for advanced peripheral vascular disease and presented 3 weeks postoperatively with pain, erythema and discharge from the incision site in the left lower abdominal wall and underwent multiple debridement of the affected area. Pathology of debrided tissue indicated extensive necrosis involving the adipose tissue, fascia and skeletal muscle. Wound cultures were positive for Serratia marcescens. She was successfully treated with antibiotics and multiple surgical debridements. Since necrotizing fasciitis is a medical and surgical emergency, it is critical to examine infectivity trends, clinical characteristics in its causative spectrum. Using PubMed we found 17 published cases of necrotizing fasciitis caused by Serratia marcescens, and then analyzed patterns among those cases. Serratia marcescens is prominent in the community and hospital settings, and information on infection presentations, risk factors, characteristics, treatment, course, and complications as provided through this study can help identify cases earlier and mitigate poor outcomes. Patients with positive blood cultures and those patients where surgical intervention was not provided or delayed had a higher mortality. Surgical intervention is a definite way to establish the diagnosis of necrotizing infection and differentiate it from other entities.
