Abstract
BACKGROUND Foot mycoses, including onychomycoses, are worldwide infectious diseases. As part of a regional survey using randomly selected residents of in Mecklenburg-Western Pomerania, we investigated the impact of dietary habits, the presence of most frequent autoimmune diseases and current smoking on fungal skin infections in order to reveal potential new risk factors to elucidate potential preventive interventions. OBJECTIVES The identification of potential new factors that influence the development of mycosis was performed in order to derive possible preventive measures. METHODS In the Study of Health in Pomerania (SHIP) in Mecklengburg-Western Pomerania, 2523 inhabitants were examined for mycotic lesions and asked about nutritional habits, the presence of atopic dermatitis, allergic rhinitis, psoriasis and smoking habits. RESULTS In all, 8% of probands were diagnosed with mycosis, 6.5% onychomycosis, 3.7% tinea pedis and 0.2% tinea corporis. Psoriasis, allergic rhinitis and atopic dermatitis and frequent consumption of cooked potatoes, oatmeal and corn flakes, cereals, pasta and rice were significantly associated with tinea pedis. Onychomycosis was positively associated with consumption of cooked potatoes. Cigarette consumption proved protective for tinea pedis and dermatophyte colonization. CONCLUSIONS The autoimmune disorders psoriasis and atopic dermatitis and allergic rhinitis seem to predispose to foot mycosis. Recalcitrant mycosis should raise the question of diets high in carbohydrates. Nicotine abuse seems to protect against skin mycosis and colonization.

Abstract
Fungal infections in humans resulting from human or animal contact are relatively uncommon, but they include a significant proportion of dermatophyte infections. Some of the most commonly encountered diseases of the integument are dermatomycoses. Human or animal contact may be the source of all types of tinea infections, occasional candidal infections, and some other types of superficial or deep fungal infections. This narrative review focuses on the epidemiology, clinical features, diagnosis and treatment of anthropophilic dermatophyte infections primarily found in North America. Other human-acquired and zoonotic fungal infections also are discussed in brief.

Abstract
Fungal infections as a result of freshwater exposure or trauma are fortunately rare. Etiologic agents are varied, but commonly include filamentous fungi and Candida. This narrative review describes various sources of potential freshwater fungal exposure and the diseases that may result, including fungal keratitis, acute otitis externa and tinea pedis, as well as rare deep soft tissue or bone infections and pulmonary or central nervous system infections following traumatic freshwater exposure during natural disasters or near-drowning episodes. Fungal etiology should be suspected in appropriate scenarios when bacterial cultures or molecular tests are normal or when the infection worsens or fails to resolve with appropriate antibacterial therapy.

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
The effect of ultraviolet (UV) radiation from low-pressure mercury lamp against some pathogenic dermatophytes species such as Epidermophyton floccosum, Trichophyton mentagrophytes, Trichophyton rubrum, Trichophyton schoenleinii, Trichophyton tonsurans and Trichophyton violaceum suspended in thermal water was evaluated in laboratory-scale condition at various times. The main results showed that within 120 s of exposure, all species of dermatophytes are completely inactivated, which was evidenced by the absence of fungal regrowth, while after 60 s only T. tonsurans was recovered, with a reduction of 3.28 log. Shorter exposure times were not enough to completely inactivate all dermatophytes species. The samples treated with UV radiation for 120 s did not give evidence of fungal regrowth indicating that this disinfectant action is persistent over time. In conclusion, UV radiation can be proposed to reduce the risk of infection by dermatophytes eventually present in swimming pools that use thermal water.

Abstract
A growing number of people attend swimming facilities for recreational activities, rehabilitative treatments, or sport. Filamentous fungi and yeast can be isolated from contaminated air, water and surfaces and may represent a biological risk for employees and users. Here we investigated the occurrence of mycotic species, in a sample of Italian swimming pools (n = 10). Detection and identification of isolated species were achieved by cultural and morphological methods. Results revealed moderate mycotic titres and a high biodiversity. Penicillium spp., Aspergillus spp., Cladosporium spp. and Alternaria sp., were constantly detected in air and surfaces sampled by the swimming area, while pathogenic yeast Candida albicans was never detected. Fusarium spp. was the most common taxon isolated from surfaces. For one facility, we typed the genotypic profiles and studied, by genetic typing, the spatial and temporal distribution of isolates. Phylogenetic relationships between species were analysed by alignment of small ribosomal subunit RNA sequences.

Abstract
Traditional Turkish baths, Hammams, occupy a prominent place in public health in history and at present. It is well-known that baths are major sources of fungal skin infections, but according to our knowledge fungal flora of Turkish Hammams was not defined yet. In Bolu, Turkey, two Hammams were open to public and for detecting fungal flora, we collected 209 samples from different part of floors, tools and screened for the fungal pathogens. From floors of the dressing rooms, Trichophyton rubrum and Candida albicans; from slippers T. rubrum, T. mentagrophytes, Epidermophyton floccosum, Candida albicans and C. tropicalis were isolated. While we could not isolate any dermatophyte species and yeasts from the vicinity of the bath windows and walls of baths, Aspergillus spp. and Penicillium spp. were isolated from the same locations. Samples taken from marble floors of baths, central massage platforms (hottest part of the Hammam) and towels did not show any fungal growth. This report reveals that components of the Turkish Hammams have low risk for fungal contamination as a result of frequent cleaning and environmental high temperature. But shared tools like slippers were found to be an important source of fungal contamination.

Abstract
OBJECTIVES The aim of this study has been to evaluate patients with tinea pedis for their demographic data and attitudes affecting the treatment of disease, and to compare the in vitro activity of 10 antifungal agents and to relate them to their in vivo activity. METHODS Patients with positive mycological examination were enrolled in the study, and a questionnaire comprised of 22 questions was administered. A mycological culture was carried out for each specimen. The antifungal susceptibility of the subcultured species was determined for griseofulvin, terbinafine, ciclopiroxolamine, fluconazole, ketoconazole, itraconazole, bifonazole, sulconazole, oxiconazole and miconazole with microdilution. RESULTS Mycological cultures were carried out from 59 patients and there were 35 positive cultures (59.3%). The dermatophytes were Trichophyton rubrum (n = 25) and Trichophyton mentagrophytes (n = 3). The yeasts were Candida albicans (n = 7), Candida glabrata (n = 1) and Trichosporon (n = 2). In the minimum inhibitory concentration (MIC) study, the mean +/- standard error of the mean (SEM) MICs of the antifungals for T. rubrum were as follows: terbinafine 0.01 +/- 0.003, oxiconazole 0.16 +/- 0.05, sulkonazole 0.31 +/- 0.05, miconazole 0.45 +/- 0.15, itraconazole 0.74 +/- 0.01, ketokonazole 1.03 +/- 0.17, ciclopiroxolamine 1.30 +/- 0.12, bifonazole 1.94 +/- 0.51, griseofulvin 4.87 +/- 0.61, and fluconazole 17.91 +/- 3.67 microg/mL. CONCLUSION Our study supports that azoles could be used as first-line treatment, as oxiconazole is very effective for both dermatophytes and C. albicans. Correlation between in vitro results and clinical outcomes of cases of dermatophytes is still to be established and interpretive breakpoints defined, in order to increase the quality of patient care in tinea pedis.

Abstract
UNLABELLED There is no specific legislation concerning pools and others medical hydrotherapy equipments relating hygiene and security rules. For this reason, the hydrotherapy pools use the public swimming pools legislation. METHOD This article is based on literature review (database Medline and Embase--manual research). RESULTS This article offers a review of pool associated infections along with the description of the measures designed to minimise the possible transmission of infection during hydrotherapy activities such as: Technical measures: pool and premises conception, water treatments, feed tanks, air quality. Hygiene rules for patients and hospital staff and pathologies which are contra-indications to hydrotherapy activities. Microbiological and physico-chemical monitoring. DISCUSSION The infectious risk remains low with therapeutic pools. However, the development of specific legislation and surveillance should be enhanced. CONCLUSION All these measures are part of the quality assurance program that must be implemented to control the safety of these installations.

Abstract
The biodiversity and richness of keratinophilic fungal communities including dermatophytes were assessed in three stream sites and three swimming pools in the Nablus district in Palestine, using hair baiting (HBT) and surface dilution plate (SDP) techniques, over 8- and 6-month periods, respectively. The effect of wastewater effluent and selected ecological factors on these fungi in relation to species diversity and population densities were also considered. Fifty keratinophilic fungal species were recovered from the aquatic habitats studied, of which 42 were recovered from stream sites and 22 from swimming pools. Of these fungi 6 were either dermatophytes (Microsporum gypseum, and Trichophyton mentagrophytes) or dermatophyte related species (Chrysosporium merdarium, Ch. tropicum, Ch. keratinophilum and T. terrestre). The most frequently isolated species in the three pools were Acremonium strictum and Cladosporium cladosporioides, using Sabouraud dextrose agar medium (SDA). The most abundant species were Acr. strictum, and Aspergillus flavus. However, only 4 species were isolated using the SDA medium amended with 5-flurocytosine (5-FC). The most frequent and abundant species in the three stream sites using SDA medium were Geotricum candidum, and Penicillium chrysogenum. The most frequent species in the three sites using the 5-FC medium, was Paecilomyces lilacinus. Using HBT, the most abundant and frequent species in the three stream sites were G. candidum, and Pa. lilacinus, on SDA medium, and Pa. lilacinus, and Gliocladium nigrovirens on the 5-FC medium. The 5-FC medium was more suitable for the isolation of dermatophytes and closely related species than the SDA medium; 6 were recovered on 5-FC, whereas only one on the SDA medium. Variation in the levels of keratinophilic fungal populations from the three stream sites sampled 5 times over an 8-month period, followed comparable fluctuation patterns. Wastewater affected fungal population densities with the highest levels in the un-polluted stream sites, and lowest in the heavily polluted sites. Swimming pools, polluted and un-polluted stream sites were found to be rich in pathogenic and potentially pathogenic fungi.

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
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
The elite athlete has a potentially increased sensitivity to respiratory infections, rendering protective measures particularly important. Some other infections that may appear in clusters in the sports setting, such as gastroenteritis, leptospirosis, herpes simplex and viral hepatitis, also require special precautionary attention. Strenuous exercise during ongoing infection and fever may be hazardous and should always be avoided. In addition, early symptoms of infection warrant caution until the nature and severity of the infection become apparent. Because myocarditis may or may not be accompanied by fever, malaise or catarrhal symptoms, athletes should be informed about the symptoms suggestive of this disease. Although sudden unexpected death resulting from myocarditis is rare, exercise should be avoided whenever myocarditis is suspected. Guidelines are suggested for the management and counselling of athletes suffering from infections, including recommendations on when to resume training. Acute febrile infections are associated with decreased performance resulting from muscle wasting, circulatory deregulation and impaired motor coordination, which require variable amounts of time to become normalized once the infection is over.
