S069 – What’s new in dermatology What’s new in dermatologic surgery – B Coldiron • Nicotinamide 500 mg twice daily was shown to reduce the risk of new nonme- lanoma skin cancer by 23% in patients with a history of skin cancer. 3 • A large review found skin cancer screening did decrease the incidence of invasive melanoma; however, the USPSTF still does not recommend skin cancer screening due to a lack of evi- dence, an inauspicious decision as the incidence and mortality of melanoma continues to rise. 4–6 Self skin examina- tion with a partner could help with early melanoma detection. 7 • Sentinel lymph node biopsy for inter- mediate-thickness melanoma remains controversial, and Dr Coldiron reminds us that there is no survival benefit. 8 The Castle test provides a prediction similar to that with sentinel lymph node biopsy and is less invasive. • Multiple studies have linked HPV to oro- pharyngeal cancers, and HPV in smoke plumes is an under-recognised source of infection.

What’s new in pediatric dermatology – S Friedlander

• The regular use of emollients from birth may decrease the risk of atopic derma- titis (AD) by 50%. 9 • Crisaborole, a topical PDE4 inhibitor, and dupilumab, a monoclonal antibody against inflammatory mediators in the AD pathway, were approved for AD this year. • The LEAP study shifted the food allergy paradigm, and we now know that early exposure to peanuts can reduce the risk of peanut allergy. 10 References 1.
