Leung AKC, Barankin B, Lam JM, Leong KF, Hon KL. Tinea pedis: an updated review. Drugs Context 2023; 12:2023-5-1. [PMID: 37415917 PMCID: PMC10321471 DOI: 10.7573/dic.2023-5-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2023] [Accepted: 06/02/2023] [Indexed: 07/08/2023] Open
Abstract
Background Tinea pedis is one of the most common superficial fungal infections of the skin, with various clinical manifestations. This review aims to familiarize physicians with the clinical features, diagnosis and management of tinea pedis. Methods A search was conducted in April 2023 in PubMed Clinical Queries using the key terms 'tinea pedis' OR 'athlete's foot'. The search strategy included all clinical trials, observational studies and reviews published in English within the past 10 years. Results Tinea pedis is most often caused by Trichophyton rubrum and Trichophyton interdigitale. It is estimated that approximately 3% of the world population have tinea pedis. The prevalence is higher in adolescents and adults than in children. The peak age incidence is between 16 and 45 years of age. Tinea pedis is more common amongst males than females. Transmission amongst family members is the most common route, and transmission can also occur through indirect contact with contaminated belongings of the affected patient. Three main clinical forms of tinea pedis are recognized: interdigital, hyperkeratotic (moccasin-type) and vesiculobullous (inflammatory). The accuracy of clinical diagnosis of tinea pedis is low. A KOH wet-mount examination of skin scrapings of the active border of the lesion is recommended as a point-of-care testing. The diagnosis can be confirmed, if necessary, by fungal culture or culture-independent molecular tools of skin scrapings. Superficial or localized tinea pedis usually responds to topical antifungal therapy. Oral antifungal therapy should be reserved for severe disease, failed topical antifungal therapy, concomitant presence of onychomycosis or in immunocompromised patients. Conclusion Topical antifungal therapy (once to twice daily for 1-6 weeks) is the mainstay of treatment for superficial or localized tinea pedis. Examples of topical antifungal agents include allylamines (e.g. terbinafine), azoles (e.g. ketoconazole), benzylamine, ciclopirox, tolnaftate and amorolfine. Oral antifungal agents used for the treatment of tinea pedis include terbinafine, itraconazole and fluconazole. Combined therapy with topical and oral antifungals may increase the cure rate. The prognosis is good with appropriate antifungal treatment. Untreated, the lesions may persist and progress.

Abstract
This study investigates foot sweat distribution with and without shoes and the relationship between foot sweat distribution and perceived wetness to enhance guidance for footwear design. Fourteen females performed low-intensity running with nude feet and low- and high-intensity running with shoes (55%VO2max and 75%VO2max, respectively) on separate occasions. Right foot sweat rates were measured at 14 regions using absorbent material applied during the last 5 min of each work intensity. Perceptual responses were recorded for the body, foot and four foot regions. Foot sweat production was 22% greater nude (p < .001) and with shoes did not increase with exercise intensity (p = .14). Highest sweat rates were observed at the medial ankle and dorsal regions; lowest sweat rates at the toes. Perceptions of wetness and foot discomfort did not correspond with regions of high sweat production or low skin temperature but rather seemed dominated by tactile interactions caused by foot movement within the shoe. Practitioner summary: This study provides a detailed view of foot sweat distribution for female runners with and without shoes, providing important guidance for sock and footwear design. Importantly, perceptions of wetness and foot discomfort did not correspond with areas of high sweat production. Instead tactile interactions between the foot, sock/shoe play an important role. Abbreviations: VO2max: maximal oxygen consumption; HR: heart rate; RH: relative humidity; GSL: gross sweat loss; Nude-I1: without socks and shoes, low intensity running; Shod-I1: with socks and shoes, low intensity running; Shod-I2: with socks and shoes, high intensity running.

Abstract
Shoe microclimate (temperature and humidity) has been suggested to contribute to perceptions of foot thermal comfort. However, limited data is available for perceptual responses in relation to shoe microclimate development both over time and within different areas of the shoe. This study evaluates perceptions of foot thermal comfort for two running shoes different in terms of air permeability in relation to temporal and spatial characteristics of shoe microclimate. The temporal characteristics of shoe microclimate development were similar for both shoes assessed. However, higher temperatures and humidity were observed for the less permeable shoe. Changes to shoe microclimate over time and differences between shoes were perceivable by the users. This study provides the most detailed assessment of shoe microclimate in relation to foot thermal comfort to date, providing relevant information for footwear design and evaluation.

Abstract
Dermatophytes are keratinophilic fungi that infect keratinized tissues causing diseases known as dermatophytoses. Dermatophytes are classified in three genera, Epidermophyton, Microsporum, and Trichophyton. This investigation was performed to study the prevalence of dermatomycosis among 640 patients being evaluated at the dermatology clinics at Kasr elainy, El-Husein and Said Galal hospitals in Cairo and Giza between January 2005 and December 2006. The patients were checked for various diseases. Tinea capitis was the most common clinical disease followed by tinea pedis and tinea corporis. Tinea cruris and tinea unguium were the least in occurrence. Tinea versicolor also was detected. The most susceptible persons were children below 10 years followed by those aged 31-40 years. Unicellular yeast was the most common etiological agent and T. tonsuranswas the second most frequent causative agent followed by M. canis.

Abstract
CONTEXT Footwear should be designed to avoid trauma and injury to the skin of the feet that can favor bacterial and fungal infections. Procedures and substances for sanitizing the interior of shoes are uncommon but are important aspects of primary prevention against foot infections and unpleasant odor. OBJECTIVE To evaluate the efficacy of a sanitizing technique for reducing bacterial and fungal contamination of footwear. DESIGN Crossover study. SETTING Mens Sana basketball team. PATIENTS OR OTHER PARTICIPANTS Twenty-seven male athletes and 4 coaches (62 shoes). INTERVENTION(S) The experimental protocol required a first sample (swab), 1/shoe, at time 0 from inside the shoes of all athletes before the sanitizing technique began and a second sample at time 1, after about 4 weeks, April 2012 to May 2012, of daily use of the sanitizing technique. MAIN OUTCOME MEASURE(S) The differences before and after use of the sanitizing technique for total bacterial count at 36 °C and 22 °C for Staphylococcus spp, yeasts, molds, Enterococcus spp, Pseudomonas spp, Escherichia coli , and total coliform bacteria were evaluated. RESULTS Before use of the sanitizing technique, the total bacterial counts at 36 °C and 22 °C and for Staphylococcus spp were greater by a factor of 5.8 (95% confidence interval [CI] = 3.42, 9.84), 5.84 (95% CI = 3.45, 9.78), and 4.78 (95% CI = 2.84, 8.03), respectively. All the other comparisons showed a reduction in microbial loads, whereas E coli and coliforms were no longer detected. No statistically significant decrease in yeasts (P = .0841) or molds (P = .6913) was recorded probably because of low contamination. CONCLUSIONS The sanitizing technique significantly reduced the bacterial presence in athletes' shoes.

Abstract
The aim of this study was to determine the prevalence of dermatomycosis and the risk factors in those who perform their prayers in the mosques in the city center of Adana Province. The diagnosis of dermatomycosis was made on the basis of direct microscopy and/or culture in addition to clinical findings. Among 461 subjects, 136 (29.5%) had tinea pedis, 23 (5.0%) had tinea unguium, and 21 (4.5%) had both infections simultaneously, with a resulting total of 180 (39.0%) cases of dermatomycosis. The causative agents by frequency were: Trichophyton rubrum (67.0%), T. mentagrophytes var. interdigitale (31.1%), and Candida albicans (1.9%). The prevalence of the foot dermatomycosis was found to be high among those who practiced ablution 3-5 times a day and did not dry their feet immediately, who used rubber shoes, and/or who shared their shoes. Pedal dermatophyte infection seems to be a major problem among the adult Muslim male population regularly attending mosques especially in 5th and 6th decades of life.

Abstract
BACKGROUND Tinea pedis is a commonly encountered dermatophytic infection with a clinical prevalence of 15-25%. Limited studies have evaluated the prevalence of occult tinea pedis. OBJECTIVES The aims of this study were to evaluate the prevalence of occult tinea pedis in asymptomatic subjects with feet that appeared healthy and to identify possible related risk factors. METHODS A prospective study of 221 asymptomatic subjects with apparently normal feet was conducted. All subjects completed a questionnaire covering anamnestic details (personal and family histories of tinea pedis, preferred footwear) and were examined for foot odor and the clinical presence of tinea pedis and onychomycosis. Samples were taken from the foot for direct microscopic examination and culture. RESULTS Among the 221 patients, 31 (14.0%) were positive for occult tinea pedis. Positive cultures from both the anterior and posterior aspects of the foot were obtained in 22 patients. The most common pathogen isolated was Trichophyton rubrum. Strong correlations emerged between occult tinea pedis and characteristics such as male gender, foot odor, previous personal and family histories of tinea pedis, and clinical and mycological evidence of onychomycosis. No significant associations were found between occult tinea pedis and age or preferred footwear. CONCLUSIONS The prevalence of occult tinea pedis is similar to that of clinical tinea pedis. This may imply that patients with subclinical infection carry a risk for transmitting disease similar to that of clinical carriers. This is of great importance in the prevention and management of the disease as high-risk asymptomatic carriers can be identified.

Abstract
Tinea pedis, which is a dermatophytic infection of the feet, can involve the interdigital web spaces or the sides of the feet and may be a chronic or recurring condition. The most common etiological agents are anthropophiles, including Trichophyton rubrum sensu stricto, which is the most common, followed by Trichophyton interdigitale and Epidermophyton floccosum. There has been a change in this research arena, necessitating a re-evaluation of our knowledge on the topic from a multidisciplinary perspective. Thus, this review aimed to provide a solid overview of the current status and changing patterns of tinea pedis. The second half of the twentieth century witnessed a global increase in tinea pedis and a clonal spread of one major etiologic agent, T. rubrum. This phenomenon is likely due to increases in urbanization and the use of sports and fitness facilities, the growing prevalence of obesity and the aging population. For optimal patient care and management, the diagnosis of tinea pedis should be verified by microbiological analysis. In this review, we discuss the epidemiology, clinical forms, complications and mycological characteristics of tinea pedis and we highlight the pathogenesis, prevention and control parameters of this infection.

Abstract
BACKGROUND About 15% of the world population have fungal infections of the feet (tinea pedis or athlete's foot). There are many clinical presentations of tinea pedis, and most commonly, tinea pedis is seen between the toes (interdigital) and on the soles, heels, and sides of the foot (plantar). Plantar tinea pedis is known as moccasin foot. Once acquired, the infection can spread to other sites including the nails, which can be a source of re-infection. Oral therapy is usually used for chronic conditions or when topical treatment has failed. OBJECTIVES To assess the effects of oral treatments for fungal infections of the skin of the foot (tinea pedis). SEARCH METHODS For this update we searched the following databases to July 2012: the Cochrane Skin Group Specialised Register, CENTRAL in The Cochrane Library, MEDLINE (from 1946), EMBASE (from 1974), and CINAHL (from 1981). We checked the bibliographies of retrieved trials for further references to relevant trials, and we searched online trials registers. SELECTION CRITERIA Randomised controlled trials of oral treatments in participants who have a clinically diagnosed tinea pedis, confirmed by microscopy and growth of dermatophytes (fungi) in culture. DATA COLLECTION AND ANALYSIS Two review authors independently undertook study selection, 'Risk of bias' assessment, and data extraction. MAIN RESULTS We included 15 trials, involving 1438 participants. The 2 trials (71 participants) comparing terbinafine and griseofulvin produced a pooled risk ratio (RR) of 2.26 (95% confidence interval (CI) 1.49 to 3.44) in favour of terbinafine's ability to cure infection. No significant difference was detected between terbinafine and itraconazole, fluconazole and itraconazole, fluconazole and ketoconazole, or between griseofulvin and ketoconazole, although the trials were generally small. Two trials showed that terbinafine and itraconazole were effective compared with placebo: terbinafine (31 participants, RR 24.54, 95% CI 1.57 to 384.32) and itraconazole (72 participants, RR 6.67, 95% CI 2.17 to 20.48). All drugs reported adverse effects, with gastrointestinal effects most commonly reported. Ten of the trials were published over 15 years ago, and this is reflected by the poor reporting of information from which to make a clear 'Risk of bias' assessment. Only one trial was at low risk of bias overall. The majority of the remaining trials were judged as 'unclear' risk of bias because of the lack of clear statements with respect to methods of generating the randomisation sequence and allocation concealment. More trials achieved blinding of participants and personnel than blinding of the outcome assessors, which was again poorly reported. AUTHORS' CONCLUSIONS The evidence suggests that terbinafine is more effective than griseofulvin, and terbinafine and itraconazole are more effective than no treatment. In order to produce more reliable data, a rigorous evaluation of different drug therapies needs to be undertaken with larger sample sizes to ensure they are large enough to show any real difference when two treatments are being compared. It is also important to continue to follow up and collect data, preferably for six months after the end of the intervention period, to establish whether or not the infection recurred.

Abstract
OBJECTIVE To present recommendations for the prevention, education, and management of skin infections in athletes. BACKGROUND Trauma, environmental factors, and infectious agents act together to continually attack the integrity of the skin. Close quarters combined with general poor hygiene practices make athletes particularly vulnerable to contracting skin diseases. An understanding of basic prophylactic measures, clinical features, and swift management of common skin diseases is essential for certified athletic trainers to aid in preventing the spread of infectious agents. RECOMMENDATIONS These guidelines are intended to provide relevant information on skin infections and to give specific recommendations for certified athletic trainers and others participating in athletic health care.

Abstract
Dermatologic conditions are a common presenting complaint in the athletic training room. There are many different causes for rashes, and treatment options vary depending on the condition and the severity. Bacterial infections of the skin have a variety of different appearances and can spread rapidly among individuals. Healthcare providers need to be aware of the increasing prevalence of methicillin-resistant Staphylococcus aureus when making the choice of antibiotics. Other infectious rashes, including tinea and herpes, are well-described conditions in wrestlers; however, these rashes can be seen in any athlete, especially those engaged in contact sports. Early recognition and appropriate treatment are important to clear the rash and reduce the spread to others. In addition to infectious rashes, athletes are prone to mechanical rashes and skin conditions due to friction and tight-fitting equipment. Sports medicine providers must not only diagnose and treat these conditions but also be aware of the return-to-play guidelines set forth by the governing bodies under which he or she operates.

Abstract
BACKGROUND Tinea pedis, known as Athlete's foot, is a common fungal infection of the feet, the majority of cases caused by dermatophytes. Copper oxide has potent antimicrobial and antifungal properties. OBJECTIVE A pilot study designed to examine the efficacy of treating tinea pedis utilizing copper-oxide impregnated fibers woven into socks worn on a daily basis. METHODS Fifty-six patients, ranging in age from 21 to 85 years were clinically diagnosed, photographed, and treated with the copper soled socks. Eight variables were studied, including scaling, erythema, fissuring, burning or itching, vesicular eruptions, edema, odor, and drainage. RESULTS In a 9-day average follow up, all patients showed improvement or resolution of erythema (with a 95% Confidence interval (CI) of 1.0), fissuring (CI=1.0), vesicular eruptions (CI=1.0), scaling (CI=0.9-1.0) and for burning and itching (CI=0.61-0.95). In a 40-day average follow up, the 95% CI for improvement or resolution of scaling was 0.68-0.97, for erythema, 0.65-0.97, and for fissuring, burning and itching and vesicular eruptions it was 1.0. None of the study subjects worsened or showed adverse reactions while wearing copper-oxide impregnated socks. CONCLUSION This study strongly supports the effectiveness in using copper-oxide impregnated polyester fibers in treating the common manifestations of tinea pedis.

Abstract
Tinea pedis is the most common dermatophytosis requiring topical antifungals for at least 1-4 weeks. To determine the effectiveness of a novel topical single dose formulation of terbinafine (film forming solution-FFS) in the treatment of tinea pedis, 344 outpatients from 43 dermatological centres in France and Bulgaria suffering from tinea pedis with possible extension to soles confirmed by mycological examination (direct and culture) were evaluated for efficacy of terbinafine 1%, 5%, 10% FFS in a randomised double blind vehicle controlled parallel group dose finding study. Evaluations were carried out at baseline, 1 and 6 weeks after a single application of FFS. Effective treatment rate based on negative mycology (direct and culture) and minimal signs and symptoms (two or less with only mild recorded) was measured at week 6. Effective treatment rates at week 6 with terbinafine 1%, 5% and 10% FFS were 66%, 70%, 61% compared with 18% with placebo. All three active preparations were shown to be significantly superior to placebo (P < 0.001). Terbinafine 1% and 5% FFS were shown to be non-inferior to terbinafine 10% FFS. Terbinafine 1% FFS is an effective, safe dose for the treatment of tinea pedis. This novel product represents a significant advance with the enhanced compliance and convenience that it offers.

Abstract
As the United States comes increasingly closer to being the heaviest nation on earth, many people are turning to exercise, especially running, to lose weight. Most runners, whether novice or professional, will have a skin disorder that may prompt them to seek medical attention. Although case reports and sports reviews have discussed, in a cursory fashion, the nature of these skin lesions, to our knowledge there has never been an extensive review of the literature that specifically addresses the skin diseases of runners. In this article, we present the epidemiology, origin, clinical characteristics, treatment, and prevention of skin diseases inherent to runners.

Abstract
Epidemiological studies on tinea pedis and onychomycosis, common fungal infections, have been conducted in many parts of the world. There are currently no studies of tinea pedis and/or onychomycosis in Algeria. The aim of this paper was to study the epidemiology of foot diseases, including tinea pedis and onychomycosis and to identify the aetiological factors of these infections in outpatients attending the Department of Dermatology of the Central Hospital of Army in Algiers, Algeria. A total of 1300 male subjects, mean age 35.9 +/- 16 years (range: 16-80) were recruited during the period November 2003 to November 2004 and were clinically examined. A complete dermatological examination was performed on all subjects, and skin and nail specimens of the feet were taken from those patients presenting signs of tinea pedis and/or onychomycosis for microscopy and fungal culture. Clinical diagnosis for tinea pedis and onychomycosis was suspected in 249 and 72 subjects, respectively, and confirmed in 197 and 60 cases, respectively, by positive cultures, resulting in a global prevalence of tinea pedis and toenail onychomycosis of 15% and 4.6% respectively. The age groups most commonly infected were 50-59 and 20-29 years. The yeast species Candida parapsilosis and the dermatophytic species Trichophyton rubrum were shown to be the most common pathogens in both tinea pedis (C. parapsilosis 20.4%; T. rubrum 17%) and onychomycosis (T. rubrum 35%; C. parapsilosis 28.3%). This is the first investigation dealing with fungal foot diseases in Algeria. The clinical and epidemiological data collected would serve as reference for future research and may be useful in the development of preventive and educational strategies.

Abstract
Dermatophyte infections and onychomycosis are not usually serious in term of mortality; however, they may have significant clinical consequences such as secondary bacterial infections, chronicity, therapeutic difficulties and esthetic disfigurement in addition to serving as a reservoir of infection. Our aim was to determine the prevalence of onychomycosis and dermatophytosis in a selected high risk group, consisting of male boarding school residents. A total of 410 males inhabiting two houses were evaluated by two dermatologists. In cases of clinical suspicion, appropriate samples were taken for direct microscopy and culture. The results showed that the prevalences of tinea pedis (athlete's foot) and pure pedal onychomycosis were 51.5% (n:211) and 4.4% (n:18), respectively. Thirty cases of those with tinea pedis were complicated by toenail onychomycosis. Tinea cruris was present only in five cases with tinea pedis. Interestingly 71.1% of those with tinea pedis and 45.8% of those with onychomycosis, associated with or without tinea pedis were unaware of their diseases. The most common fungal isolate was Trichophyton rubrum (76.6%) followed by Epidermophyton floccosum (11.6%), T. interdigitale (10.55%). Approximately one third of the cultures from nail specimens yielded pure growths of nondermatophyte moulds or Candida albicans. In conclusion, we found unexpectedly high prevalences of occult athlete's foot and toenail onychomycosis among the male residents of student houses. Our results indicate that health-care workers of such common boarding-houses should be more aware of clinical and subclinical dermatophyte infections and onychomycosis, and have more active approaches to educational measures and management strategies to prevent further infections. To our knowledge, this is the first epidemiologic study on the prevalences of dermatophytosis and onychomycosis in boarding-houses from Turkey.

Abstract
BACKGROUND Limited studies on the prevalence and risk factors for superficial mycoses are available. OBJECTIVE The aim of this paper was to evaluate the prevalence and risk factors for superficial mycoses (dermatophytes and Candida spp.) in a sample of young Italian people resident at a military school. METHODS A total of 1,024 young cadets from the Italian Navy Petty Officers School in Taranto, including 975 (95.21%) males and 49 (4.79%) females, mean age 22.5 +/- 3.0 years (range 18-30), were consecutively examined by the same observer. A complete dermatological examination was performed on all the subjects, and skin scrapings for microscopy and fungal culture were obtained from suspected lesions. All the subjects completed a questionnaire providing information on sports practice, swimming-pool attendance, marching, wearing shower sandals, frequent use of 'gummed' shoes, history of severe traumas to the nails, presence of hyperhidrosis and history of superficial mycoses. The affected subjects were also asked if they were aware of their condition. Data were analysed by the Statistical Analysis System, version 8.0. The Fisher exact test and odds ratios were calculated. RESULTS A total of 33 subjects (3.2%) were found to suffer from a mycologically confirmed fungal infection (3% by dermatophytes and 0.2% by Candida albicans): tinea pedis/Candida intertrigo of the feet was suspected in 126 (12.1%) subjects and confirmed in 30 (2.9%), including 28 cases of tinea pedis and 2 cases of Candida intertrigo; tinea cruris/Candida intertrigo of the groin was suspected in 28 (2.7%) subjects, but confirmed in only 1 case (0.1%); onychomycosis was suspected in 64 (6.1%) subjects and confirmed in 2 cases (0.2%). The organism most frequently responsible in tinea pedis was Trichophyton mentagrophytes var. interdigitale (82.1%). The same species (50%) and T. mentagrophytes var. mentagrophytes (50%) were associated with tinea unguium, Epidermophyton floccosum was the only species detected in tinea cruris. Non-dermatophytic filamentous fungi (Penicillium spp., Fusarium spp., Aspergillus spp. and Paecilomyces spp.), not considered pathogenic, were isolated in 48 samples. None of the risk factors analysed were significantly associated with fungal infection. Only 2 subjects out of the 33 people affected were aware of their condition. They both had tinea pedis. CONCLUSION The prevalence of mycoses in sailors living in an Italian military school was lower than rates detected in other military populations. This may be due to the cadets' lifestyle and environmental conditions. The most frequent infection was tinea pedis, mainly caused by T. interdigitale. None of the investigated risk factors were significantly associated with the disease, and most of the affected individuals were not aware of their condition.

Abstract
Copper ions, either alone or in copper complexes, have been used for centuries to disinfect liquids, solids, and human tissue. Today copper is used as a water purifier, algaecide, fungicide, nematocide, molluscicide, and antibacterial and antifouling agent. Copper also displays potent antiviral activity. We hypothesized that introducing copper into clothing, bedding, and other articles would provide them with biocidal properties. A durable platform technology has been developed that introduces copper into cotton fibers, latex, and other polymeric materials. This study demonstrates the broad-spectrum antimicrobial (antibacterial, antiviral, antifungal) and antimite activities of copper-impregnated fibers and polyester products. This technology enabled the production of antiviral gloves and filters (which deactivate HIV-1 and other viruses), antibacterial self-sterilizing fabrics (which kill antibiotic-resistant bacteria, including methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococci), antifungal socks (which alleviate symptoms of athlete's foot), and anti-dust mite mattress covers (which reduce mite-related allergies). These products did not have skin-sensitizing properties, as determined by guine pig maximization and rabbit skin irritation tests. Our study demonstrates the potential use of copper in new applications. These applications address medical issues of the greatest importance, such as viral transmissions; nosocomial, or healthcare-associated, infections; and the spread of antibiotic-resistant bacteria.

Abstract
BACKGROUND Dermatophyte infections have been considered rare in psoriasis. However, there are data indicating that tinea unguium is as common or even more common in psoriasis compared with healthy controls. Tinea unguium is generally a secondary event to tinea pedis infection. OBJECTIVES To study the prevalence of tinea pedis and tinea unguium in psoriasis compared with a control group. METHODS Consecutive psoriasis outpatients aged 18-64 years attending a department of dermatology were examined. Samples for direct microscopy and culture were taken from the interdigital spaces, soles and toenails. Consecutive patients without signs of psoriasis or atopic dermatitis seeking examination of moles constituted the control group. RESULTS In total, 239 patients with psoriasis and 245 control patients were studied. The prevalence of tinea pedis was 8.8%[95% confidence interval (CI) +/- 3.6%] in the psoriasis group and 7.8% (95% CI +/- 3.4%) in the control group. The corresponding figures for prevalence of tinea unguium were 4.6% (95% CI +/- 2.7%) and 2.4% (95% CI +/- 1.9%), respectively. The differences found in the psoriasis vs. the control groups were not statistically significant. CONCLUSIONS This study does not support the hypothesis that the prevalence of tinea pedis and tinea unguium in patients with psoriasis differs from that in a normal population.

Abstract
OBJECTIVE To provide an insight into the prevalence of foot disease in Europe, and to include an assessment of the prevalence of predisposing factors and their correlation with foot disease. DESIGN Large population-based survey conducted in 16 European countries. SETTING The project consisted of two parts (study I and study II), in which all patients presenting to general practitioners and dermatologists over a defined time period were invited to participate. Patients. In study I, 70,497 patients presenting to dermatologists or general practitioners were recruited, and in study II 19,588 patients presenting to dermatologists were recruited. MAIN OUTCOME MEASURE The feet of all participants were examined for signs of foot disease. The assessors also recorded relevant details such as the age and sex of patients, and the presence of predisposing factors for foot disease. In addition, patients in study II were offered a free mycological examination of the toenails and skin on the feet. RESULTS In study I, 57.0% of patients had at least one foot disease. In study II, 61.3% had at least one foot disease. The proportions of patients with fungal foot disease and non-fungal foot disease in study I were 34.9% and 38.4%, respectively, and in study II were 40.6% and 41.7%, respectively. Orthopedic conditions and metatarsal corns were the most frequently reported non-fungal foot diseases, and onychomycosis and tinea pedis were the most frequently observed fungal infections. CONCLUSIONS This large-scale survey suggests that the prevalence of fungal and non-fungal foot disease is higher than previously estimated.

Abstract
In this study, we investigated epidemiological and clinical aspects of dermatophyte foot infections among employees of one dairy product company located in Kanagawa prefecture in central Japan. Sixty-nine of 377 subjects were reported having "athlete's foot" in response to a simple questionnaire. A subsequent mycological examination revealed 41 untreated patients with tinea pedis and/or tinea unguium (89% of subjects examined) and the overall prevalence was estimated at 18%. Comparing severity scores of five clinical symptoms (itching, erythema, vesicles/pustules, erosion/maceration, and scales) between those untreated patients within the subjects and another group of patients who spontaneously attended dermatological clinics to treat tinea pedis, itching, erythema, and total score were significantly higher in the latter group.

Abstract
UNLABELLED Terbinafine, an orally and topically active antimycotic agent, inhibits the biosynthesis of the principal sterol in fungi, ergosterol, at the level of squalene epoxidase. Squalene epoxidase inhibition results in ergosterol-depleted fungal cell membranes (fungistatic effect) and the toxic accumulation of intracellular squalene (fungicidal effect). Terbinafine has demonstrated excellent fungicidal activity against the dermatophytes and variable activity against yeasts and non-dermatophyte molds in vitro. Following oral administration, terbinafine is rapidly absorbed and widely distributed to body tissues including the poorly perfused nail matrix. Nail terbinafine concentrations are detected within 1 week after starting therapy and persist for at least 30 weeks after the completion of treatment. Randomized, double-blind trials showed oral terbinafine 250 mg/day for 12 or 16 weeks was more efficacious than itraconazole, fluconazole and griseofulvin in dermatophyte onychomycosis of the toenails. In particular, at 72 weeks' follow-up, the multicenter, multinational, L.I.ON. (Lamisil vs Itraconazole in ONychomycosis) study found that mycologic cure rates (76 vs 38% of patients after 12 weeks' treatment; 81 vs 49% of recipients after 16 weeks' therapy) and complete cure rates were approximately twice as high after terbinafine treatment than after itraconazole (3 or 4 cycles of 400 mg/day for 1 week repeated every 4 weeks) in patients with toenail mycosis. Furthermore, the L.I.ON. Icelandic Extension study demonstrated that terbinafine was more clinically effective than intermittent itraconazole to a statistically significant extent at 5-year follow-up. Terbinafine produced a superior complete cure rate (35 vs 14%), mycologic cure rate (46 vs 13%) and clinical cure rate (42 vs 18%) to that of itraconazole. The mycologic and clinical relapse rates were 23% and 21% in the terbinafine group, respectively, compared with 53% and 48% in the itraconazole group. In comparative clinical trials, oral terbinafine had a better tolerability profile than griseofulvin and a comparable profile to that of itraconazole or fluconazole. Post marketing surveillance confirmed terbinafine's good tolerability profile. Adverse events were experienced by 10.5% of terbinafine recipients, with gastrointestinal complaints being the most common. Unlike the azoles, terbinafine has a low potential for drug-drug interactions. Most pharmacoeconomic evaluations have shown that the greater clinical effectiveness of oral terbinafine in dermatophyte onychomycosis translates into a cost-effectiveness ratio superior to that of itraconazole, fluconazole and griseofulvin. CONCLUSION Oral terbinafine has demonstrated greater effectiveness than itraconazole, fluconazole and griseofulvin in randomized trials involving patients with onychomycosis caused by dermatophytes. The drug is generally well tolerated and has a low potential for drug interactions. Therefore, terbinafine is the treatment of choice for dermatophyte onychomycosis.

Abstract
An epidemiological investigation was conducted to determine the prevalence and circumstances of untreated, unsuspected tinea pedis and tinea unguium, morbid conditions that could be termed occult athlete's foot, in patients visiting a dermatology clinic in Tokyo, Japan, for the first time, for other complaints. All subjects completed a questionnaire covering comprehensive anamnestic details, and were examined for disposition of toes, presence of signs suggestive of tinea pedis, other diseases of the foot, score of clinical signs and symptoms, potassium hydroxide (KOH) test, severity score, and mycological culture. The results showed that the prevalence of occult athlete's foot was 25%, and that 59% of those cases were complicated by tinea unguium. The characteristics of patients with occult athlete's foot included a higher proportion of men and a tendency toward a low clinical score together with a high severity score. In the patient background, a strong correlation was observed between a positive KOH test result and characteristics such as age, disposition of toes, and predisposing disease.

Abstract
The aim of this study was to verify the incidence of tinea pedis in patients observed in the Department of Dermatology of the University of Cagliari, Italy, in the period from 1996 to 2000. We examined 722 patients, 536 with lesions and 186 without lesions of the feet and in 169 of them (23.4%) we diagnosed tinea pedis. All patients suffering from tinea pedis belonged to the group with lesions. In the 536 patients with clinical manifestations which were evident to a certain degree, microscope and cultural examination gave positive results for dermatophytes in 169 cases (31.5%). The most frequently isolated dermatophyte was Trichophyton mentagrophytes (51.5%), followed by Trichophyton rubrum (45.2%) and Epidermophyton floccosum (3.3%). In the 186 patients without lesions, direct microscope examination was consistently negative while cultural examination showed the growth of sparse colonies of Candida albicans in two cases (1.1%) We analysed distribution by sex, age, residence, occupation and clinical manifestations. Stressing the high frequency of tinea pedis in this region, the discovery of a dermatophytic infection of the feet with an absence of signs and symptoms is an exceptional event.

Abstract
BACKGROUND Epidemiological studies suggest that 15% of the population in industrial countries suffer from tinea pedis (athlete's foot) and that persons who do sports are a high-risk population. OBJECTIVE To investigate the responsibility of dermatophytes in interdigital lesions of the feet in European marathon runners and to identify associated risk factors. SUBJECTS AND METHODS Runners of the 14th Médoc Marathon (n = 147) were interviewed on risk factors for tinea pedis and underwent physical and mycological examinations. RESULTS Interdigital lesions of the feet were found in 66 runners (45%). A dermatophyte was isolated in 45 runners (31%), 12 of whom were asymptomatic. Trichophyton interdigitale and T. rubrum accounted for 49% and 35.5%, respectively, of the cases of tinea pedis. Thirty-three (22%) of the 102 runners free of dermatophyte infection had lesions resembling those of tinea pedis. Increasing age and use of communal bathing facilities were predictive of T. rubrum culture. CONCLUSIONS Marathon runners are at high risk for tinea pedis, but dermatophytes are responsible for only half of the foot lesions found in runners. The existence of asymptomatic carriers calls for prophylactic measures.

Abstract
BACKGROUND About 15% of the population have fungal infections of the feet (tinea pedis or athlete's foot). Whilst there are many clinical presentations of tinea pedis the most common are between the toes (interdigital) and on the soles, heels and sides of the foot (plantar) which is known as moccasin foot. Once acquired the infection can spread to other sites including the nails, which can be a source of reinfection. Oral therapy is usually used for chronic conditions or when topical treatment has failed. OBJECTIVES To assess the effects and costs of oral treatments for fungal infections of the skin of the foot (tinea pedis). SEARCH STRATEGY Randomised controlled trials were identified from MEDLINE, EMBASE and CINAHL from the beginning of these databases to January 2000. We also searched the Cochrane Controlled trials Register (Cochrane Library issue 1, 2000) the Science Citation Index, BIOSIS, CAB-Health, Health star and Economic databases. Bibliographies were searched, podiatry journals hand searched and the pharmaceutical industry and schools of podiatry contacted. SELECTION CRITERIA Randomised controlled trials including participants who have a clinically diagnosed tinea pedis, confirmed by microscopy and growth of dermatophytes in culture. DATA COLLECTION AND ANALYSIS Study selection was done by two independent reviewers. Methodological quality assessment and data collection was also assessed by two independent reviewers. MAIN RESULTS Twelve trials, involving 700 participants, were included. The two trials comparing terbinafine and griseofulvin produced a pooled risk difference of 52% (95% confidence intervals 33% to 71%) in favour of terbinafine's ability to cure infection. No significant difference was detected between terbinafine and itraconazole; fluconazole and either itraconazole and ketoconazole; or between griseofulvin and ketoconazole, although the trials were generally small. Two trials showed that terbinafine and itraconazole were effective compared with placebo. Adverse effects were reported for all drugs, with gastrointestinal effects most commonly reported. REVIEWER'S CONCLUSIONS The evidence suggests that terbinafine is more effective than griseofulvin and that terbinafine and itraconazole are more effective than no treatment.

Abstract
We investigated visitors to a swimming pool in Reykjavik to determine whether onychomycosis of the toenails is more prevalent in swimmers than in the general population, where the prevalence is believed to be between 3 and 8%. A total of 266 swimmers over the age of 17 years were interviewed and examined. When an onychomycosis was suspected a nail specimen was taken for mycological examination. Onychomycosis was clinically suspected in 105 cases (40%). In 60 cases (23%) a dermatophyte infection was confirmed by culture and 14 cases (5%) were microscopy-positive only. The prevalence of culture-positive onychomycosis was 15% in women and 26% in men. Our results suggest that onychomycosis of the toenails is at least 3 times more prevalent in swimmers than in the rest of the population.

Abstract
Tinea pedis is a common inflammatory skin condition due to infection by dermatophyte fungi. A number of epidemiological studies have been completed on the frequency of tinea pedis in the community, particularly sporting and occupational groups and schools. Most studies have focused on small, high-risk populations. These include occupational groups involving manual labour, sporting groups such as swimmers, and those working or living in confined conditions with shared washing facilities, which favour the opportunity for cross-infection. Most studies show that the frequency of tinea pedis is higher in males than females. Tinea pedis infections appear to be least common among children, but do occur, and are commonly misdiagnosed. The difference between clinical disease and confirmed diagnosis by culture is not always clear when statistics of disease frequency have been presented. Clear diagnosis criteria indicating the level of mycologically confirmed diagnosis should be reported in future studies that include statistics on disease frequency. Future epidemiological studies should also aim to be population-based in order to obtain a more complete picture of disease frequency.

Abstract
A survey of dermatophytes and dermatophytoses was carried out among patients of the Department of Dermatology, Medical University of Gdańsk, in the years 1984-95. Over the 12-year period, 1195 cases of ringworm were seen: 55% in men and 45% in women. Listing the dermatophytes isolated and their frequencies as a percentage of the total are as follows: Trichophyton mentagrophytes 42.1%, Microsporum canis 26.0%, Trichophyton rubrum 14.7%, Epidermophyton floccosum 11.0%, Trichophyton tonsurans 4.6%, Trichophyton verrucosum 1.3%, Trichophyton violaceum 0.3%. The most common clinical variant of dermatophytosis in the Gdańsk area was tinea cutis glabrae (32.9%), followed by tinea pedis (24%), onychomycosis (16.5%), tinea capitis (11.9%)), tinea inguinalis (10.3%) and tinea manuum (4.4%). Dermatophytoses were significantly more frequent among adults (> 15 years) (71.3%).

Abstract
The epidemiology of human dermatophytes was studied in northern Finland in 1982-90. The samples were analysed at the Department of Medical Microbiology, University of Oulu. The total number of samples was 17,822, of which 3185 (18%) were positive. The annual number of samples and positive cultures remained relatively constant. Trichophyton rubrum was the most common species being isolated from 2101 samples (66% of all positive cultures), while Trichophyton mentagrophytes was isolated from 815 samples (26%) and Epidermophyton floccosum from 193 samples (6%). T. verrucosum caused an epidemic among cattle keepers in 1987-90, causing 47 infections. Microsporum canis, T. terrestre and T. violaceum were rare. The same species affected both children and adults. There was a tendency towards a decrease in tinea in the groin and a slight increase in tinea pedis. T. rubrum and T. mentagrophytes occurred most frequently in patients aged 41-45 years and as foot infections. E. floccosum usually affected the toe web and the groin in patients aged 21-25 years, more often infecting men. Fifty-four per cent of all positive samples came from men and 46% from women.

Abstract
The etiologic agents of the dermatophytoses (ringworm) are classified in three anamorphic (asexual or imperfect) genera, Epidermophyton, Microsporum, and Trichophyton. Species capable of reproducing sexually belong in the teleomorphic genus, Arthroderma, of the Ascomycota. On the basis of primary habitat association, they may be grouped as geophilic (soil associated), zoophilic, and anthropophilic. Adaptation to growth on humans by most geophilic species resulted in diminished loss of sporulation, sexuality, and other soil-associated characteristics. The dermatophytes have the ability to invade keratinized tissue (skin, hair, and nails) but are usually restricted to the nonliving cornified layer of the epidermis because of their inability to penetrate viable tissue of an immunocompetent host. However, invasion does elicit a host response ranging from mild to severe. Acid proteinases, elastase, keratinases, and other proteinases reportedly act as virulence factors. The development of cell-mediated immunity correlated with delayed hypersensitivity and an inflammatory response is associated with clinical cure, whereas the lack of or a defective cell-mediated immunity predisposes the host to chronic or recurrent dermatophyte infection. Chronic dermatophytosis is mostly caused by Trichophyton rubrum, and there is some evidence that mannan produced by this fungus suppresses or diminishes the inflammatory response. Since dermatophytes cause a communicable disease, modes of transmission and control are discussed as well as a survey of recent trends in therapy. Collection of specimens, culture media, and tests for identification are also presented. Genetic studies have led to an understanding of incompatibility mechanisms, pleomorphism and variation, resistance to griseofulvin, and virulence. Molecular biology has contributed to our knowledge of the taxonomy and phylogenetic relationships of dermatophytes.

Abstract
Dermatophytic infections are very common in Greece. In the Mycological Laboratory of the Venereal and Skin Diseases Hospital in Thessaloniki, 6572 isolates of different dermatophytes were obtained from 17,120 patients examined. It is suggested that 5% of the people who present with skin problems in Greece suffer from dermatophyte infections. They are frequent causative agents of tinea pedis, tinea cruris, tinea corporis, tinea capitis and tinea unguium. In this paper, the species, the number and the prevalence of the dermatophytes were studied according to location and sex of the patients. The contribution of dermatophyte infections to the overall incidence of superficial fungal infection over 10 years was also studied.
