Randomized Controlled Trial Clinical TrialPrilocaine/lidocaine patch as a local premedication for skin biopsy in children.
Prilocaine-lidocaine emulsion (EMLA) has been used successfully as a local anesthetic in patients undergoing superficial procedures. ⋯ The anesthetic patch reduced the pain experienced by children subjected to a skin biopsy procedure.

ReviewAntimicrobial agents for the dermatologist. II. Macrolides, fluoroquinolones, rifamycins, tetracyclines, trimethoprim-sulfamethoxazole, and clindamycin.
This article is the second of a two-part series reviewing antimicrobial agents that are used by the dermatologist. In part I we reviewed beta-lactam antibiotics and related compounds. In this section we again emphasize some newer agents (macrolides, fluoroquinolones) as well as some of the more commonly employed older agents (rifamycins, tetracyclines, trimethoprim-sulfamethoxazole, and clindamycin.

ReviewCombined topical calcipotriene ointment 0.005% and various systemic therapies in the treatment of plaque-type psoriasis vulgaris: review of the literature and results of a survey sent to 100 dermatologists.
Plaque-type psoriasis may at times require systemic therapy. There are limited data as to whether topical calcipotriene ointment 0.005% can be used to increase the efficacy and improve the risk/benefit ratio of concurrent systemic antipsoriatic therapy. ⋯ Combination therapy with calcipotriene ointment and acitretin/etretinate, cyclosporine, methotrexate, or phototherapy usually enhances efficacy while improving the risk/benefit ratio by decreasing exposure to the potentially hazardous systemic agent.

A major controversy in the treatment of melanoma is the width of the surgical margin necessary for complete excision. Although surgical margins have decreased in recent years, the current recommendations are mainly based on arbitrary choices, only two of which have been tested in clinical trials. ⋯ Predetermined surgical margins for excision of melanoma or melanoma in situ by standard surgical techniques should include 1 cm of normal-appearing skin for melanomas on the trunk and proximal extremities that are smaller than 2 cm in diameter, or a 1.5 cm margin for tumors larger than 2 cm in diameter. For melanomas on the head, neck, hands, and feet, a minimum surgical margin of 1.5 cm is recommended or a margin of 2.5 cm for melanomas larger than 3 cm in diameter. Mohs micrographic surgery is a useful alternative to standard surgery when more narrow margins are desired, particularly for melanomas on the head, neck, hands, and feet, or melanomas larger than 2.5 cm in diameter, or for melanomas without distinct clinical margins.
