A newly formulated topical triple-antibiotic ointment minimizes scarring.

A randomized study of polymyxin B sulfate-bacitracin zinc-neomycin sulfate versus simple gauze-type dressings in dermabrasion wounds assessed the effects that each treatment had on scarring. Each of three uniform dermabrasion wounds created on the upper backs of 70 subjects was treated concurrently with a triple-antibiotic ointment (polymyxin B-bacitracin-neomycin), a double antibiotic (polymyxin B-bacitracin), or a simple, non-occlusive, gauze-type dressing, twice daily for up to 14 days. Pigmentary changes and textural changes (scarring) appearing after healing at the skin surface test sites were compared to adjacent normal skin at 45 and 90 days post-dermabrasion. These changes were graded visually utilizing fluorescent light, long-wave ultraviolet light, and by clinical color photography. The triple-antibiotic ointment was superior to simple gauze-type dressing alone in minimizing the scarring observed in dermabrasion wounds. The benefit of this new ointment was more pronounced in its effect on pigmentary changes.

Open-label study of the safety and efficacy of naftifine hydrochloride 1 percent gel in patients with distal subungual onychomycosis of the fingers.

Optimal topical therapy for distal subungual onychomycosis is not available. An open-label study was performed to determine the safety and efficacy of naftifine hydrochloride (Naftin) 1 percent gel in patients with this disorder of the fingers. Ten patients with culture-proven distal subungual onychomycosis were treated twice daily for six months with naftifine hydrochloride 1 percent gel. At monthly intervals, the target nail was trimmed, the nail bed debrided, and global clinical assessment recorded. Following months three, six, and eight (two months after treatment), the target nail underwent evaluation with potassium hydroxide wet mount and fungal culture. After six months of therapy, eight of ten patients showed negative results of fungal culture and eight of ten patients showed clinical improvement. Adverse effects were minimal and included mild peeling in two patients and mild fissuring with transient fingertip numbness in one patient.

Open-label study of the safety and efficacy of Fungoid tincture in patients with distal subungual onychomycosis of the toes.

Onychomycosis is the most frequent cause of nail diseases. An open-label study has been conducted to evaluate the safety and efficacy of Fungoid Tincture, a topical antifungal agent approved by the Food and Drug Administration for the treatment of onychomycosis of the toes. Ten patients with culture-proven distal subungual onychomycosis were treated twice daily for twelve months with topical Fungoid Tincture. Another ten patients with the same condition were treated with the vehicle alone. At monthly intervals, the target nail was trimmed, the nail bed debrided, and global clinical assessment recorded. After twelve months of therapy, all patients applying Fungoid Tincture showed negative findings on fungal culture. The vehicle alone benefitted several patients, and may have antifungal activity. Adverse effects were minimal, with mild peeling occurring in seven patients and erythema noted in one.

Nail disorders in children.

The spectrum of nail abnormalities that may be seen in the pediatric population is discussed in this article. Developmental abnormalities, both hereditary and congenital, are discussed. Acquired nail abnormalities that may be similar to those seen in adults are also described.

Congenital malalignment of the great toenails.

Congenital malalignment of the great toenails is a disorder in which malalignment of the nail matrix results in angular lateral nail plate growth. The consequence is onychodystrophy, which may progress to onychogryphosis and chronic ingrown toenails. There has been debate as to whether the condition is inherited or acquired in utero secondary to improper fetal positioning. A 6-year-old boy and his father, both of whom have this disorder, are discussed.

Longitudinal pigmented nail bands.

In this article, we have discussed the possible causes of a longitudinal pigmented nail band. A thorough history, physical examination, and, when indicated, biopsy of the origin of the band should reassure the patient with a benign lesion and direct further treatment of a patient with a malignant or potentially malignant lesion.
