A review of the epidemiology of tinea unguium in the community.

Tinea unguium is a common, chronic fungal infection of the nails. Many epidemiological studies have looked at the frequency with which this condition is seen in hospital outpatients clinics or mycological laboratories along with other dermatomycoses. Only recently have studies begun to emerge looking at the prevalence of this condition in populations. Hospital and mycological laboratory-based studies give valuable information about tinea unguium prevalence in a particular clinic, but cannot be compared with other studies due to confounding factors inherent in the different people attending individual clinics. From population-based studies the prevalence of tinea unguium lies between 2 and 8%. Tinea unguium increases steadily with age. It is infrequent but definitely found in children. With the increasing life expectancy in the Western world the prevalence of tinea unguium is likely to increase further without adequate prevention and treatment.

Scrubbing for cutaneous procedures can be hazardous.

Office-based minor cutaneous surgery is a service provided by many medical practitioners. In New South Wales, Australia, it is a legal requirement for practitioners to surgically scrub before donning sterile gloves for all forms of invasive surgery, including minor cutaneous procedures. Frequent scrubbing causes altered skin barrier function, irritant dermatitis and a potential risk of latex sensitization. These adverse effects are associated with significant morbidity and cost. Better tolerated alternatives, including alcohol-based hand rubs, should be considered in preference to traditional surgical scrubs in order to reduce these occupational risks for minor proceduralists. Well-controlled, prospective studies should explore what extent of hand washing is necessary for donning sterile gloves for minor cutaneous surgery.

Itraconazole pulse therapy for the treatment of Candida onychomycosis.

In this open label, multicentre trial, 44 patients with clinical and mycological evidence of Candida onychomycosis were treated with itraconazole pulse therapy. Onychomycosis of the toes alone and concomitant disease involving the fingers and toes was treated with three pulses, and onychomycosis of the fingers alone with two pulses. Final evaluation for patients with finger and toe onychomycosis was at 6-9 months and 9-12 months, respectively. There were 29 patients with toe onychomycosis (C. albicans, 27; C. glabrata, one; Candida species, one), 12 patients with finger onychomycosis (C. albicans, two; C. glabrata, one) and three patients had combined toe and finger onychomycosis (C. albicans, two; C. guillermondii, one). In the patients with toe onychomycosis mycological cure was observed in 29 of 32 patients (90.6%). There was complete cure [mycological cure (negative culture and KOH at endpoint evaluation) with clinical cure] or marked improvement (mycological cure with 75% or greater decrease in area of involvement of target nail compared with pretherapy) in 24 of 32 patients (75.0%). All 12 patients with finger onychomycosis alone due to Candida species achieved a mycological cure (100%). In this group of patients complete cure or marked improvement was observed in 11 of 12 patients (91.7%). Itraconazole pulse therapy was well tolerated and no serious adverse events were reported in the patients treated with this triazole. In conclusion, itraconazole pulse therapy is an effective and safe treatment for both finger and toe onychomycosis associated with Candida.

Verrucous form of chilblain lupus erythematosus.

A 45-year-old woman had symmetrical livid plaques with yellowish hyperkeratoses for 5 years, which progressed on to the fingers and toes and on the soles of the feet. Two years later creamy, whitish areas and maceration appeared on the buccal mucosa and the lips. A skin biopsy revealed massive collagen hyaline degeneration in the perivascular area, hyperkeratosis and hypergranulosis, small lymphocyte infiltrates with several melanophages and extravasates of erythrocytes in the upper corium in perivascular areas and hydropic degeneration of basal keratinocytes. The findings using direct immunofluorescence were compatible with lupus erythematosus (LE). Laboratory investigation showed a slight leucopenia and thrombopenia, a slightly elevated erythrocyte sedimentation rate, hypocomplementaemia C3 and C4, a high titre of rheumatoid factor and antinuclear antibodies positivity of extractable nuclear antigen. The results reflected probably the development of a systemic form of the disease. The patient was successfully managed by methylprednisolone and hydroxychloroquine. After 1 year of therapy, a new skin biopsy revealed a substantial reduction of hyperkeratosis and hyaline degeneration of collagen tissue in the perivascular areas. The combination of the extensive hyperkeratosis and hyalinization thus seems to be features of the long-lasting, untreated lesions in chilblain LE.

Hyperpigmentation mimicking Laugier syndrome, levodopa therapy and Addison's disease.

The Laugier-Hunziker syndrome is an acquired, idiopathic, benign mucocutaneous hypermelanosis that usually occurs on the lips and oral mucosa, although it may appear at other sites. Nails are frequently involved, mainly forming longitudinal hyperpigmented bands. We report the case of a patient that presented a typical picture of this entity, nearly 1 year after the beginning of treatment with levodopa. Two years after the first lesions occurred, she developed Addison's disease. The patient suffered from a diffuse discrete hyperpigmentation (it was more remarkable on exposed areas) and an intensification of the melanotic macules that were previously noticeable before in oral and genital mucosa, fingers, toes and nails. Hormonal replacement treatment enabled the control of laboratory and general manifestations and to decrease the degree of mucocutaneous hyperpigmentation considerably, despite initial hyperpigmented lesions persisting in described areas.

Palmoplantar eccrine hidradenitis: three new cases and review.

Palmoplantar eccrine hidradenitis (PEH) is characterized by painful erythematous papules and nodules of abrupt onset on the soles of young individuals. The histologic hallmark is a predominant neutrophilic infiltrate surrounding the eccrine gland apparatus. A total of 28 cases have been published since 1988, with a broad variation in the age of patients, symptomatology, associated diseases, clinical course, and histologic features. These different histologic pictures have resulted in several names for this entity, including idiopathic plantar hidradenitis, neutrophilic eccrine hidradenitis, recurrent palmoplantar hidradenitis in children, and idiopathic palmoplantar hidradenitis. We present three cases of this disorder and review the literature on the varying symptomatology, clinical course, and histology that have led to the myriad of names for this disease.

Onychomycosis in children: treatment with bifonazole-urea.

We assessed the safety and efficacy of a two-phase topical treatment with bifonazole-urea ointment in children with onychomycosis. Twenty-five children younger than 16 years old with proved onychomycosis were included in the study. Bifonazole-urea ointment was administered under occlusion until the nontraumatic removal of the nail was achieved. Bifonazole cream was then applied for 4 weeks and a follow-up visit 4 weeks after cessation of medication was scheduled. During the study, periodic clinical and mycologic evaluations were carried out. Of the 25 patients included, 17 were cured (68%), 6 improved, and 2 failed treatment. The main etiologic agent isolated was Trichophyton rubrum (92%). Two patients had minor side effects, both during the occlusive phase, one each with mild pain and a probable dermatitis from the adhesive strips. Treatment was not discontinued in both of these cases. We concluded that a two-phase treatment with bifonazole-urea is effective and safe, and represents a new therapeutic choice for onychomycosis in children.

Dermal tolerance and effect on skin hydration of a new ethanol-based hand gel.

We studied the dermal tolerance (repetitive occlusive patch test; ROPT) and the skin hydrating properties of a new ethanol-based gel [85% (w/w)], Sterillium Gel. For the ROPT, 53 participants were studied. Gel was applied to one site on the back under an occlusive patch during an induction phase (nine applications over three weeks) and two weeks later to a virgin site on the back during a challenge phase (one application). Twenty-four hours after the removal of the patches (induction phase and challenge phase), then 48 and 72 h later (challenge phase) sites were graded for skin reactions using a standardized scale. In the induction phase none of the 53 participants had a skin reaction. In the challenge phase one participant had a barely perceptible skin reaction, and one had mild erythema at one time point. To evaluate skin hydrating properties of the gel, treated skin of 21 participants was compared to untreated skin. The gel was applied twice a day to the forearm for 14 days. Control corneometer values were taken before application of the gel (mean: 32.7 +/- 5.0) and after one (36.3 +/- 4.4) and two weeks (36.1 +/- 5.4). Relative skin hydration on treated skin in comparison with an untreated control field was significantly higher after one week by 6.85% (P = 0.0031; paired t -test for dependent samples) and after two weeks by 4.47% (P = 0.0153). Sterillium Gel did not demonstrate a clinically relevant potential for dermal irritation or sensitization, and significantly increased skin hydration after repetitive use, and so could enhance compliance with hand hygiene among healthcare workers.

Pulsed dye laser therapy for viral warts.

Twenty-eight patients with 103 recalcitrant and 20 simple viral warts were treated with the Cynosure PhotoGenica V pulsed dye laser at 585 nm, and fluencies of 6.0-9.0 J/cm(2). An eradication rate of 92% for recalcitrant warts after an average of 2.1 (range 1-7) treatments and 75% for simple warts after an average of 1.6 (range 1-2) treatments was achieved with a mean follow-up period of 7.2 (range 3-15) months. Mild hypopigmentation was noted in one patient and superficial infection in another. Unlike ablative treatment modalities, with pulsed dye laser therapy, no wound was created thus avoiding prolonged postoperative pain, disability and scarring. Treatment was well tolerated by patients, most of whom returned to work or normal activities immediately postoperatively. Pulsed dye laser is an effective treatment for both recalcitrant and simple warts. It is the treatment of choice for these lesions in cosmetically sensitive areas.
