Abstract
Onychomycosis and tinea pedis are common fungal infections affecting the nails and feet, respectively. Two newly approved topical agents for onychomycosis are efinaconazole and tavaborole, both of which have demonstrated respectable cure rates in clinical studies. For tinea pedis, naftifine 2% and luliconazole 1% are new agents, both administered for relatively short courses, that may foster greater adherence Semin Cutan Med Surg 35(supp6):S110-S113 © 2016 published by Frontline Medical Communications © 2016 published by Frontline Medical Communications

Onychomycosis is a common fungal infection affecting the nails. In the general population, the prevalence of onychomycosis is low—about 4% in one systematic review1—but the prevalence is much higher in certain populations, such as elderly patients (16%), those with diabetes (14%), psoriasis (16%), or human immunodeficiency virus (11%), or those receiving dialysis (14%) or renal transplant (7%). It is especially important in immunosuppressed or immunocompromised patients, who may harbor unusual fungal species (eg, saprophytes rather than dermatophytes). Onychomycosis may be considered a cosmetic problem by many clinicians, but the condition can lead to pedal pain and breaks in the skin that both facilitate lower extremity cellulitis and allow for exposure of the bloodstream to infectious fungal agents.

Educational Needs
Research continues to expand our understanding of the pathophysiology and management of skin diseases and age-related skin damage. Based on this evidence, new pharmacologic agents and medical devices continue to be developed, researched, and approved for use in the United States. New evidence and therapies have been developed for acne vulgaris, rosacea, psoriasis, onychomycosis/tinea, and facial rejuvenation. Clinicians need to understand the safety and efficacy of these new therapies in specific patient types.
Acne vulgaris affects 40 to 50 million people in the United States, with a prevalence as high as 85% in teenagers. A wide range of effective treatment strategies are now available to manage acne vulgaris, and new agents continue to be developed, offering an enhanced range of options. Psoriasis is an inflammatory skin disease for which a variety of agents, including several tumor necrosis factor (TNF) inhibitors, are approved for treatment. Recently, the use of TNF inhibitors for pediatric psoriasis has been investigated, and new biosimilar agents are in late stages of development for psoriasis. Clinicians may be reluctant to use TNF inhibitors in children with psoriasis and do not yet have clinical experience with biosimilar agents.
Rosacea is a common chronic skin condition affecting the face, affecting approximately 14 million Americans. No cure exists for rosacea, but health care professionals have several options to treat the symptoms, including new agents to treat facial erythema and inflammation. The use of these agents requires an understanding of their safety and use in combination therapy. Onychomycosis and tinea pedis are common fungal infections affecting the nails and feet, respectively. Newly approved topical agents for onychomycosis and tinea have demonstrated high cure rates in clinical studies.
Among the most common cosmetic procedures performed in the United States are the use of botulinum toxin A, soft tissue fillers, and laser treatments. In the last decade, a multitude of new products and devices have been developed for these indications, including new soft tissue fillers and novel laser technologies. The increased availability of options also increases the challenge of selecting the most appropriate agent or combination of agents for each patien
