Various aluminum salts were evaluated for in vitro and in vivo antimicrobial activity and ability to bind with serum proteins (astrigency) with the object of finding a colorless substance to substitute for carbol-fuchsin solution (Castellani paint) in the treatment of symptomatic interdigital athlete's foot. Aluminum chlorohydrate was more powerful in killing bacteria and fungi than aluminum acetate and aluminum chloride. However, aluminum chloride showed pronounced astringency and was the only compound to bring about rapid resolution of the signs and symptoms of athlete's foot in open-ended clinical trials. This salt promptly controls odor, pruritus, and maceration. The beneficial effect depends largely on drying the surface, not killing organisms. A solution of 30% aluminum chloride was found to be equlvalent to carbol-fuchsin solution in effectively treating symptomatic athlete's foot.

Tea tree oil (an essential oil derived primarily from the Australian native Melaleuca alternifolia) has been used as a topical antiseptic agent since the early part of this century for a wide variety of skin infections; however, to date, the evidence for its efficacy in fungal infections is still largely anecdotal. One hundred and four patients completed a randomized, double-blind trial to evaluate the efficacy of 10% w/w tea tree oil cream compared with 1% tolnaftate and placebo creams in the treatment of tinea pedis. Significantly more tolnaftate-treated patients (85%) than tea tree oil (30%) and placebo-treated patients (21%) showed conversion to negative culture at the end of therapy (p < 0.001); there was no statistically significant difference between tea tree oil and placebo groups. All three groups demonstrated improvement in clinical condition based on the four clinical parameters of scaling, inflammation, itching and burning. The tea tree oil group (24/37) and the tolnaftate group (19/33) showed significant improvement in clinical condition when compared to the placebo group (14/34; p = 0.022 and p = 0.018 respectively). Tea tree oil cream (10% w/w) appears to reduce the symptomatology of tinea pedis as effectively as tolnaftate 1% but is no more effective than placebo in achieving a mycological cure. This may be the basis for the popular use of tea tree oil in the treatment of tinea pedis.

Studies were conducted to assess the bioequivalence of a new antimycotic formulation, ciclopirox olamine lotion 1%, to an established compound, ciclopirox olamine cream 1%. Results of in vitro studies, using skin samples from human cadavers and domestic pigs, demonstrated that the two formulations equally penetrate all layers of the stratum corneum and inhibit the growth of Trichophyton mentagrophytes and Candida albicans. In vivo studies in guinea pigs and in human volunteers demonstrated the comparable therapeutic efficacy of the lotion and the cream in experimental trichophytosis. In addition, a multicenter, double-blind clinical trial was undertaken to compare ciclopirox olamine lotion 1% with the vehicle alone in the treatment of patients with tinea pedis. Patients with plantar, interdigital, or vesicular tinea pedis were enrolled in the studies. Patients were treated for 28 days. Clinical and mycological responses were determined during treatment and two weeks posttreatment. Ciclopirox olamine lotion 1% was found to be significantly more effective than its vehicle in the treatment of patients with common tinea pedis. Minor localized side effects (pruritus, burning sensation) were reported in 2% of 89 patients treated with ciclopirox olamine lotion 1%. The results demonstrate the bioequivalence of ciclopirox olamine lotion 1% and ciclopirox olamine cream 1% and confirm the clinical effectiveness and safety of the lotion in the treatment of tinea pedis, a generally recalcitrant fungal infection. It is concluded that ciclopirox olamine lotion 1% can be used as an alternative to ciclopirox olamine cream 1% for treatment of tinea pedis, tinea versicolor, tinea cruris, tinea corporis, and cutaneous candidiasis when the convenience and/or cosmetic elegance of a lotion is desired.

The prevalence of Gram-negative bacilli on the toewebs was 8% in normal students, 24% in hospital outpatients with suspected Tinea pedis, 41% in industrial workers wearing protective clothing and 58% in coal miners. Prevalence was greatest in those exposed to wet working conditions. In miners, the presence of Gram-negative bacilli was related to symptoms of itching/soreness and cracking/fissuring, and was negatively related to malodour, but this latter trend was reversed in outpatients and in industrial workers. The feet are a source of many 'enteric' and 'environmental' bacilli and could contribute to infection elsewhere than in the toewebs themselves.

Providing dermatologic care in a prison setting is a challenge to the practitioner's ingenuity and patience because of cumbersome methods of transporting prisoners, poor compliance with prescribed regimens, and follow-up care that is not only inadequate but almost nonexistent. Certain prevalent infections such as tinea pedis and condyloma acuminatum probably are specifically induced by the prison environment. Alopecia areata is unexpectedly common and apparently associated with stress. Pruritus, which is common, is related to both environment and stress. Dermatologic diseases seen commonly in blacks are more prevalent because of the population demographics, yet pseudofolliculitis barbae is unusual as a complaint. In this article we review our experiences in establishing a first in-prison dermatology clinic.

In an attempt to provide clinically relevant data regarding both dermatologic disease and skin care needs in the elderly, 68 noninstitutionalized volunteers, aged 50 to 91 years (average age, 74 years), were enrolled in a study consisting of a 33-item questionnaire and a total cutaneous examination. Two thirds of the entire group and 83% of the 23 octogenarians reported medical concerns regarding their skin, with pruritus as the most frequent complaint. On examination, all subjects had at least one cutaneous abnormality, and symptomatic and/or medically significant disorders were present in 64.7%. In decreasing order of prevalence, disorders for which dermatologic therapy was judged desirable included actinic keratoses, tinea pedis, contact dermatitis, seborrheic dermatitis, stasis dermatitis, and skin cancer. Overall, there was rather poor correlation between the subjects' complaints and perceptions and objective physical findings. Further, despite a high prevalence and long average duration of dermatologic concerns, very few subjects had consulted a physician for these problems, and no complaints other than "rashes" and pruritus had ever been discussed with any health care professional. Review of skin care regimens revealed substantial limitations with regard to bathing, shampooing, and nail care, particularly for subjects aged 80 years or older. Despite a small sample size and possibility of selection bias among the subjects, these data strongly suggest that skin problems are common among the elderly and that at present their dermatologic needs are largely unmet.

One hundred fifty-one patients with tinea pedis participated in a double-blind study to assess the efficacy and safety of a powder containing undecylenic acid 2% and zinc undecylenate 20% versus a placebo powder. Patients were assigned to apply twice-daily applications of either active powder or placebo for a period of 4 weeks. Trichophyton rubrum or Trichophyton mentagrophytes were isolated from pretreatment cultures of 85 patients. Of these, 88% treated with active powder had negative cultures after 4 weeks compared with 17% of those treated with placebo powder (p less than 0.001). Fungus was identified in potassium hydroxide (KOH) treated skin scrapings of all 151 patients before treatment. Of those treated with active powder, 80% were KOH negative after 4 weeks compared with 49% of those treated with placebow powder (p = 0.001). Erythema and scaling were significantly improved by therapy with active powder, as were subjective evaluations of itching and burning. There were no side-effects or adverse reactions to undecylenic acid and its zinc salt.

Croconazole hydrochloride is a new antifungal agent of the imidazole type. A 1% croconazole cream (Pilzcin, Merz + Co., D-Frankfurt/Main) was investigated in a multicentre trial involving 132 patients (mean age 46.7 +/- 15.5 years; 69 men, 63 women) suffering from tinea pedis (interdigital space, n = 86; other foot sites, n = 46). The fungal infections were caused predominantly by Trichophyton rubrum (interdigital space, n = 43; other foot sites, n = 33), followed by other Trichophyton and Candida species. The patients were treated once daily for a period of up to 3 weeks. In the majority of cases complete cure was achieved at both locations. On fungal microscopy no fungi were seen after 3 weeks in 82.6% of patients in the 'interdigital space' group and in 80.4% of patients in the 'other foot sites' group. Two weeks after the end of the treatment no fungi could be found in culture in 81.4% of the patients in the 'interdigital space' group and in 80.4% of patients in the other group. All skin symptoms of the mycoses (itching, scaling, erosions, reddening) decreased during the observation period. In 82.6% of patients in the 'interdigital space' group and in 76.1% of patients treated in the 'other foot sites' group efficacy was rated by the physician as good or very good. Tolerability was evaluated as good or very good in 90.7% and 89.1% of the cases. Local skin intolerabilities were not observed. The therapeutic results show that croconazole cream, when applied once a day, is an effective and well-tolerated drug for the treatment of tinea pedis, regardless of its location.

Superficial dermatophytoses of skin are very common infections seen in clinical practice. Besides topical imidazoles, triazoles and allylamines, topical butenafine (a benzylamine derivative) is a novel agent with broad antifungal activity. One hundred and eleven patients with tinea infections were enrolled in this multicentric, randomised, single-blind non-comparative study, which involved application of butenafine (1%) cream in tinea pedis (4 weeks) and tinea cruris and tinea corporis (2 weeks) cases. The results showed that butenafine causes rapid resolution of signs and symptoms (erythema itching, burning, crusting, scaling, etc), with good patient and physician acceptability of treatment. The broader spectrum fungicidal activity and better drug retention in superficial skin layers may be responsible for this beneficial effect.

The effects of two topical cream formulations containing clotrimazole 1% and ketoconazole 2%, respectively, were clinically compared in a double-blind, randomized manner for a 28-day therapy of interdigital tinea pedis in 106 treated patients. Ketoconazole was to be used twice daily whereas clotrimazole was administered only once daily. The primary response criterion defined as the number of patients with cure or improvement after 28 treatment days was comparable with 62.0% vs. 64.0% (clotrimazole vs. ketoconazole) for the full analysis set of 100 (50 vs. 50) patients. The mycological response revealed a negative culture and microscopy in 53.1% vs. 52.1% of the patients after 14, in 76.0% vs. 79.2% after 28, and in 83.7% vs. 76.9% after 56 days of observation, indicating a possibly better long-term efficacy of clotrimazole. The development of the overall score of tinea-related signs and symptoms did not show relevant differences between the two drugs and continuously decreased from 11+/-5 in both groups at baseline to 2+/-2 vs. 2+/-1 at day 56. As to the remission and improvement rates of single symptoms, better results were obtained under clotrimazole than under ketoconazole particularly for pruritus (97.8 vs. 89.6%) and burning/stinging (97.5 vs. 89.4%) which both are perceived as most bothersome by the patients. Furthermore, both substances appeared as comparably safe and well tolerable (8 vs. 7 adverse events with only 1 vs. 3 drug related). In conclusion, a successful therapy of tinea pedis can be achieved with both clotrimazole and ketoconazole within 28 days of treatment and once-daily clotrimazole is equally effective as twice-daily ketoconazole with favourable influences on the most irritating symptoms of the disease. Mycological and reliable clinical cure cannot be observed during two weeks after start of treatment.
