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.

Background: It is difficult to carry out studies on the prevalence of tinea pedis in the community. Some studies are performed on selected groups of subjects, exposed to the same risk factors, i.e. schoolchildren, public bathers, athletes and military men. Objective: The aim of this work was to detect in a sample of military men the prevalence of tinea pedis and the awareness of their condition, and to relate the infection to risk factors of the group as well. Methods: 410 male Italian navy cadets in an Italian navy petty officers school were clinically examined and mycological cultures were performed, employing the skin scrapings obtained from suspected lesions. Results: Dermatophytes were isolated from toe clefts in 10 subjects, giving a point prevalence of 2.4% (95% confidence interval 1.3–4.4%). The isolated dermatophytes were Trichophyton mentagrophytes (70%), Trichophyton rubrum (20%) and Epidermophyton floccosum (10%). None of the subjects was aware of his disease. No significant association was observed between tinea pedis and risk factors (i.e. hyperhidrosis and habits). Conclusion: The prevalence in our sample was lower than that observed in previous studies on military men. That can be attributed to the general amelioration of hygienic conditions and strengthening of preventive habits. Therefore the prevalence of tinea pedis in Italian sailors seems to be reduced but still rather relevant. That is important because these subjects are a reservoir of ringworm infection.

INTRODUZIONE E SCOPO DELLA RICERCA L'isolamento dalle urine di lieviti del genere Candida è frequente nella popolazione ospedalizzata e la loro presenza può essere dovuta ad una banale contaminazione (da nicchie ecologiche dove il lievito è normalmente presente, quali -ad esempio -la vagina e il perineo), ad una transitoria colonizzazione o ad una infezione a carico dell'apparato urinario conseguente alla progressione del lievito dalle basse vie urinarie oppure ad una sua diffusione per via ematica in un quadro di candidosi disseminata (2, 7, 9). I molti interrogativi diagnostici e terapeutici posti dall'isolamento di lieviti dalle urine (4, 5, 10) e soprattutto la possibilità che il loro ritrovamento possa essere indice di una candidosi profonda/disseminata stimolarono il Comitato Studio Micologia (CoSM) dell'AMCLI a proporre (3), a livello nazionale, un'indagine epidemiologica sulle candidurie allo scopo di indagarne i fattori di rischio, l'eziologia, l'approccio terapeutico, l'evoluzione micologica. L'indagine fu rivolta prevalentemente a pazienti degenti nei reparti di tera- SUMMARY:The multiple problems associated with the recovery of yeasts from urine specimens induced the Medical Mycology Committee (CoSM) of AMCLI to run a nationwide epidemiologic survey on candiduria in order to evaluate risk factors, involved species, treatment and outcome. Ten hospitals (Bergamo, Como, Crema, Novara,Varese, Ancona, Florence, Pescara, Palermo and Taranto) participated to this study, which was run on a 15-month period (October 1, 2001-December 31, 2002. Overall, 83 Data Forms were collected, regarding patients admitted to Intensive Care Units (45), Surgical (9) and Medical (29) wards. The most common risk factors were: bladder catheter, antibiotic therapy, parenteral nutrition, kidney failure, surgery. Candiduria, mostly asymptomatic, were often associated with fever and bacterial infections. Concurrent candidaemia was detected in 13 patients. Candida albicans was the most frequently recovered species, from both urine and blood, followed by C. glabrata. Other Candida species were occasionally isolated from urine specimens. Specific antifungal treatment was administered to 58% of the patients, mostly using fluconazole. The remaining subjects did not receive antimycotic therapy. Eradication of Candida from urine specimens was observed even without a specific therapy.
