Incidence and outcomes of cutaneous angiosarcoma: A SEER population-based study.

Background: Cutaneous angiosarcoma (CAS) is a rare, malignant tumor of vascular mesenchymal origin accounting for less than 1% of all sarcomas.

Objective: To examine epidemiologic trends and outcomes in CAS.

Methods: In this retrospective, population-based study, patients with CAS were identified from the Surveillance Epidemiology and End Results database.

Trends in Medicare Billing Among Mohs Surgeons in the United States During 2012: A Retrospective Cohort Study.

Background: It is important to understand variability in practice patterns of Mohs surgeons.

Objective: To examine the practice patterns of physicians performing Mohs micrographic surgery (MMS) in the United States.

Methods And Materials: This retrospective cohort study of the 2012 Medicare Physician and Other Supplier Public Use Files includes all physicians who billed Medicare for MMS.

Retrospective Evaluation of the Safety of Large Skin Flap, Large Skin Graft, and Interpolation Flap Surgery in the Outpatient Setting.

Background: As the number of cutaneous surgeries continues to increase, it is important to evaluate the safety of dermatologic surgery in the outpatient setting.

Objective: The authors sought to determine postoperative bleeding, infection, dehiscence, and necrosis rates in office-based dermatologic surgery using large flap, large graft, and interpolation flap repairs. The authors evaluated the relationship between these complications and surgical site, closure type, repair size, antibiotic use, and antithrombotic use.

Improving Sun-Protective Behaviors and Self-Skin Examinations Among African Americans: A Randomized Controlled Trial.

Background: Few studies describing sun-protective behaviors, knowledge, and self-efficacy in African Americans exist. Although educational programs targeting Caucasians and Hispanics have been successful in increasing melanoma awareness and knowledge, no such investigation has been applied to African Americans.

Objective: To evaluate the effectiveness of a brochure or video educational intervention on the sun-protective behaviors, knowledge, and self-efficacy regarding melanoma in African Americans.

Racial disparities in melanoma survival.

Background: Melanoma is a cutaneous malignancy common in the white population but can also occur in other racial groups.

Objective: We sought to evaluate survival across racial groups in patients given a diagnosis of malignant melanoma.

Methods: The Surveillance, Epidemiology, and End Results database was used to populate a cohort of 96,953 patients given a diagnosis of cutaneous melanoma as their primary cancer, from 1992 to 2009.

Green tea catechins quench the fluorescence of bacteria-conjugated Alexa fluor dyes.

Accumulating evidence suggests that Green tea polyphenolic catechins, especially the (-)-epigallocatechin gallate (EGCG), can be cross-linked to many proteins, and confer a wide range of anti-bacterial activities possibly by damaging microbial cytoplasmic lipids and proteins. At the doses that conferred protection against lethal polymicrobial infection (induced by cecal ligation and puncture), EGCG significantly reduced bacterial loads particularly in the liver and lung. To elucidate its bactericidal mechanisms, we determined whether EGCG affected the fluorescence intensities of bacteria-conjugated Alexa Fluor 488 or 594 dyes.
