OBJECTIVE: Chemical matricectomy is performed mainly by two agents: phenol and sodium hydroxide. Both agents have excellent cure rates, but there are no data about the comparison of postoperative healing periods. This study was designed to compare the postoperative morbidity rates of sodium hydroxide and phenol matricectomies. MATERIALS AND METHODS: Forty-six patients with 154 ingrowing nail sides were treated with either sodium hydroxide or phenol matricectomy...

BACKGROUND: Copper is an essential mineral involved in the formation and stabilisation of extracellular skin proteins. As copper can be absorbed through intact skin, we reasoned that using socks containing copper-impregnated fibres may have an effect on skin elasticity. METHODS: A double blind, placebo controlled study was conducted in which one group of healthy volunteers (n = 32) wore socks with fibres containing microscopic copper oxide particles and the other group wore identical socks without copper oxide (n = 28)...

Abstract Digital and interdigital corns are common painful foot conditions encountered by podiatrists during the course of their practice. These corns can often be treated using conservative techniques, although they tend to eventually reoccur. Currently, no single treatment exists that is efficient, long-lasting, minimally invasive, and easy to administer. This article describes two cases where hyaluronic acid gel injections were used to improve symptoms associated with digital and interdigital corns located in a non-weight bearing area...

PURPOSE: To enhance the learner's competence with knowledge of the effect of smoking on wound healing in patients undergoing nail matrix phenolization. TARGET AUDIENCE: This continuing education activity is intended for physicians and nurses with an interest in skin and wound care. OBJECTIVES: After participating in this educational activity, the participant should be better able to:1. Summarize factors that affect wound cicatrization and pathophysiologic mechanisms of impaired healing from smoking as found in prior studies from review of the literature...

BACKGROUND: Friction blister research has focused on prevention and treatment approaches rather than exploring the pathophysiology of the friction blister. Increased skin hydration has been purported to be a key risk factor in friction blister development. This study aimed to test the effect of increased skin surface hydration on the risk of friction blister creation. METHODS: The skin on one foot was hydrated by soaking the foot in water. Intermittent loading was carried out until an observable change of 3°C was evident using infrared thermography...
