Evaluation of 6 weeks treatment of terbinafine in tinea unguium in a double-blind trial comparing 6 and 12 weeks therapy. The Lagos V Study Group.
Terbinafine (Lamisil) has been registered throughout the world for the treatment of finger and toenail onychomycosis. The recommended duration of treatment of toenail onychomycosis based on phase III studies is 12 weeks. This study was designed to determine: (i) if patients in whom the proximal part of the toenails was not affected respond as well after 6 weeks treatment as after 12 weeks treatment; (ii) to identify factors which may allow selection of patients for shorter treatment duration; and (iii) confirm that 6 weeks therapy is sufficient in fingernail mycosis. One hundred and forty-eight patients received 250 mg terbinafine daily for either 6 or 12 weeks in a double-blinded manner, and were allowed until 48 weeks after start of therapy. Cure of the nail infection was defined as negative mycological tests (mycological cure) and progressive growth of normal nail (clinical cure). Mycological cure was recorded in 43 of 72 (59.7%) in the 6-week group and 55 of 76 (72.4%) in the 12-week group. In those who completed the study per protocol in the 6-week group, 34 of 61 (55.7%) were cured mycologically corresponding to 46 of 56 (82.1%) in the 12-week group. The overall clinical and mycological cure rates for the two groups were 28 of 61 (45.9%) and 33 of 56 (58.9%), respectively. In the small number of patients with associated fingernail infection, all were improved and six of eight (75.0%) were cured after a duration of treatment of 6 weeks. A priori risk factors for failure of cure could not be identified in either group. However, shorter duration of disease prior to treatment and no involvement of the big toenail was associated with a trend toward better responses in both groups. It can be concluded from this study that, in toenail mycosis without visible matrix involvement, 6 weeks treatment of terbinafine is generally not sufficient, whereas fingernail infections respond well to this short therapy.

Common viral and fungal skin infections.
Skin infections account for a significant portion of dermatologic diseases, often resulting in, or as a consequence of a disruption in the skin's integrity. This paper covers the presentation, diagnosis, and treatment of the more common viral and fungal skin infections. The viral infections presented in this paper include herpes simplex virus, herpes zoster, condyloma acuminata, and molluscum contagiosum. The fungal infections presented include tinea pedis, tinea cruris, tinea capitis, tinea unguium, tinea versicolor, and candidiasis. Once a diagnosis is made, treatment with appropriate antifungal, antiviral, destructive, or immune modifying therapies can be instituted.

[Clinical and epidemiological survey of dermatophytoses in Jaen (Spain)]
Prevalence of dermatophytosis, with respect to age and sex and dermatophyte species, in Jaen was investigated during a period of three years (1996-1999). The prevalence of dermatophytosis over three years was 4.48 cases / 1000 inhabitants. The isolated species were: Microsporum canis (48.6%), Trichophyton mentagrophytes (27.1%), Epidermophyton floccosum (10%), Trichophyton rubrum (8.6%), Trichophyton violaceum (4.3%), and Microsporum gypseum (1.4%). The most frequently observed dermatophytoses were tinea corporis (62.8%), followed by tinea capitis (12.8%); other clinical forms encountered were, in decreasing order of frequency, tinea cruris, tinea pedis and tinea unguium, tinea faciei and tinea barbae. Men were more affected than women.

[Analysis of dermatophyte flora at a private clinic in Sapporo during the period 1992 to 2001].
Statistical analysis was made of a total of 5530 patients (6798 cases) of dermatophytoses presenting at our private clinic during the period 1992 to 2001. The number of patients and cases represents 8.0% and 9.8% of the entire outpatient population during that time, respectively. Sex ratio (male/female) was 1.5. Among the 6798 dermatophytoses cases, tinea pedis was most frequent (65.8%), followed by tinea unguium (20.7%), tinea cruris (7.2%), tinea corporis (3.9%), tinea manuum (2.4%) and tinea barbae (0.04%). The incidence of tinea unguium increased, whereas that of tinea pedis, tinea cruris, and tinea corporis decreased during this ten year period, and 35.8% of dermatophytoses patients had more than two clinical subtypes simultaneously. Three thousand seven hundred ninety-five dermatophytes were isolated during the survey. : Trichophyton rubrum (TR)(79.4%), Trichophyton mentagrophytes (TM)(19.5%), Microsporum canis (MC)(0.7%), Epidermophyton floccosum (EF) (0.3%), and Microsporum gypseum (MG) (0.1%). Compared with our previous analysis reported for the period 1982 to 1991, the frequency of dermatophytoses increased, especially among aged individuals. Of the clinical subtypes, tinea pedis and tinea unguium were higher, but tinea cruris and tinea corporis were lower, and tinea capitis was not seen in the current survey. Among dermatophytes, TR was increased and other types of fungi were decreased. TR was 4.08 times more common than TM; this ratio is higher than our previous report.

[Epidemiological survey of dermatophytosis in Spain (April-June 2001)].
INTRODUCTION: A three-month (April-June 2001) cross-sectional study was designed to assess the epidemiological profile of dermatophytosis in Spain. METHODS: Sixty-two medical centers belonging to 14 different autonomous regions of Spain took part in the survey. A total of 491 strains were sent the Mycology Unit of the National Microbiology Center together with a form containing information on each patient. Isolates were identified by routine methods. RESULTS: The average age of the patients was 38.7 years and 55.6% were men. The most frequent dermatophytoses were tinea unguium (39.1%), tinea corporis (25.1%), tinea pedis (12.6%), and tinea capitis (11.2%). Trichophyton rubrum (43%) was the most prevalent species. T. mentagrophytes (21.2%) and Microsporum canis (9.8%) were the second and third most common species, respectively. Tinea unguium was significantly associated with urban residence, and tinea corporis with rural residence and contact with animals. T. rubrum was related with urban dermatophytosis and T. mentagrophytes with rural cases. Tinea capitis due to T. tonsurans and T. violaceum was related with patients of North African origin. Tinea unguium was the most prevalent infection by autonomous region, except in Castilla-León, Asturias, Andalucía and Aragón, where tinea corporis was the most common dermatophytosis. Tinea capitis was the most frequent infection in Castilla-La Mancha and Extremadura. T. mentagrophytes was more prevalent than T. rubrum in Valencia, Castilla-La Mancha, Aragón and Murcia. CONCLUSION: This cross-sectional study shows regional differences in the clinical and microbiological features of dermatophytosis in Spain. Epidemiological surveys are an essential tool for developing strategies for infection control.

Prevalence of dermatophytoses in the Zarqa district of Jordan.
A total of 350 clinically suspected cases of dermatomycoses were examined for causative fungi during July 1997 to September 1998. Mycotic infection was demonstrable by microscopy and culture in 199 (56.8%) cases. The most common superficial mycotic infections were tinea pedis (35.2%) followed by tinea capitis (23.1%), tinea unguium (21.6%) and tinea corporis (10.6%). Most of the infected patients were 1-9, 20-29 and 30-39 years old. Men were mainly infected with tinea cruris and tinea pedis, while women were infected with tinea pedis, tinea unguium and tinea capitis. The frequencies of etiological agents isolated from patients were as follows: Trichophyton mentagrophytes var. interdigitale (32.7%), T. rubrum (28.6%), Epidermophyton floccosum (20.1%), Microsporum canis (11.1%), T. schoenleinii (4%), T. verrucosum (2%), T. violaceum (1%), and M. gypseum (0.5%). The number of infections varied with the seasons. The highest number of cases of tinea pedis and tinea cruris occurred in the summer months, while tinea capitis, tinea corporis and tinea unguium occurred in the spring and winter months.

[Dermatophytosis of the external auditory meatus].
Dermatophytosis of the external auditory meatus is believed to be a fairly rare disease. In the past three and a half years we have had seven cases of dermatophytosis in the external auditory meatus. All cases except one were associated with tinea of other lesions. Case 1: A 44-year-old man had tinea of the auricle, tinea pedis and tinea unguium. Case 2: A 14-year-old boy, the son of case 1 had no tinea elsewhere on his body, including the auricle. He scratched the auditory meatus with an earpick which his father had used. Case 3: A 62-year-old man had tinea of the auricle, tinea pedis and tinea unguium. Case 4: A 50-year-old man had tinea of the auricle, tinea pedis and tinea unguium. Case 5: A 36-year-old man had tinea of the auricle, tinea pedis, tinea unguium and tinea cruris. Case 6: A 30-year-old woman had tinea of the auricle. Case 7: A 68-year-old man had tinea of the auricle, tinea pedis, tinea unguium and tinea manuum. Endoscopic examination (except for cases 4 and 7) revealed dry cerumen from cartilaginous to bony region of the external auditory meatus. Direct examination using KOH method of the cerumen in all cases demonstrated numerous fungal elements. Fungal cultures identified Trichophyton rubrum except for cases 3 and 6. All cases were successfully treated with oral itraconazole or terbinafine. We suggest that tinea of the external auditory meatus is frequently associated with that of the auricle.

Pedal dermatophyte infection in psoriasis.
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.

[1997 Epidemiological survey of dermatophytoses in Japan].
An epidemiological investigation on dermatophytoses in Japan for the year 1997 was carried out with the following results. The number of dermatomycoses patients visiting the fourteen cooperating institutes that year was 8,284. New outpatients with this condition accounted for 13.3% of all new outpatients in these institutes. Dermatophytoses patients numbered 7,314 and were composed of: tinea pedis 4,901 (63.8%), tinea unguium 1,592 (20.7%), tinea corporis 557 (7.2%), tinea cruris 395 (5.1%), tinea manuum 215 (2.8%), tinea capitis 12, kerion celsi 3, tinea barbae 1 and granuloma trichophyticum 1. Of these, 117 were children under 15 years of age. Species and incidences of the 2,273 strains isolated from the patients with dermatophytoses were as follows: Trichophyton (T.) rubrum 1,628 (71.6%), T. mentagrophytes 617 (27.2%), Epidermophyton floccosum 9 (0.4%), Microsporum (M.) canis 2, M. gypseum 2, T. glabrum 1, and 15 undetermined strains. Candidiasis was found in 714 individuals: intertrigo 302, erosio interdigitalis 108, erythema infantum 85, oral candidiasis 51, paronychia et onychia 51, genital candidiasis 50, onychomycosis 15 and other atypical forms of candidiasis 39. Patients with tinea versicolor numbered 242 and those with malassezia folliculitis 15. There were nine cases of deep dermal mycoses. The results of superficial dermatophytoses for the year 1997 differed from those of 1991-92 in the following points: tinea corporis and tinea cruris were lower in number, while tinea unguium had increased in ratio and number continuously. M. canis infection tended to decrease. In the age distribution of tinea, in every clinical form the peak of distribution curve gradually shifted to a more elderly age group.

An epidemiological investigation on dermatophytoses in Japan for the year 1996 was carried out with the following results. The number of dermatomycoses patients visiting the fifteen cooperating institutes that year was 8,402. New outpatients with this condition accounted for 13.1% of all new outpatients in these institutes. Dermatophytoses patients numbered 7,395 and were composed of: tinea pedis 4,764 (64.4%), tinea unguium 1,487 (20.1%), tinea corporis 558 (7.5%), tinea cruris 369 (5.0%), tinea manuum 195 (2.6%), tinea capitis 11, kerion Celsi 7, tinea barbae 1 and other forms 3. Of these, 113 were children under 15 years of age. Species and incidences of the 2,615 strains isolated from the patients with dermatophytoses were as follows: Trichophyton (T.) rubrum 1,828 (69. 9%), T. mentagrophytes 743 (28.4%) Epidermophyton floccosum 20 (0. 8%), Microsporum (M.) canis 13 (0.5%), M. gypseum 5, T. violaceum 2, and 4 undetermined strains. Candidiasis was found in 722 individuals: intertrigo 299, erosio interdigitalis 95, erythema infantum 89, oral candidiasis 63, paronychia et onychia 56, genital candidiasis 56, onychomycosis 24, chronic mucocutaneous candidiasis 1 and other atypical forms of candidiasis 39. Patients with tinea versicolor numbered 265 and those with Malassezia folliculitis 15. There were five cases of deep dermal mycoses: three of sporotrichosis, one of chromomycosis and one of aspergillosis. The results of superficial dermatophytoses for the year 1996 differed from those of 1991-92 in the following points: Tinea corporis and tinea cruris were lower in number, while tinea unguium had increased in ratio and number. M. canis infection tended to decrease gradually. In the age-distribution of tinea, in every clinical form the peak of distribution curve shifted to a more elderly age group.

Epidemiological trends of dermatophytoses and dermatophytes in Jerusalem between 1954 and 1981.
Data for dermatophyte infections analysed for five 3-year periods between 1954 to 1981 led to the following conclusions: Tinea pedis, tinea cruris and tinea manuum showed an increase in the 50's and 60's and declined in the 70's; Tinea unguium and tinea corporis showed an increase during the whole period; At all these sites, the percentage of Trichophyton rubrum, the main etiologic agent, increased steadily over the periods while the percentage of Trichophyton mentagrophytes, the secondary etiological agent, decreased. Epidermophyton floccosum, the third etiological agent in these sites, showed no sharp fluctuations; These three dermatophytes which show similar microclimatic requirements and favour the same microecological niches, were called 'glabrohydrophilic'. In tinea corporis they form a definite subset, their percentage being similar to that at other glabrous sites; Tinea capitis was at its peak in the 50's, decreased sharply until the second half of the 70's, its main etiological agent being Trichophyton violaceum. Since 1979, an increase of tinea capitis occurred due to the newly introduced Microsporum canis; Dermatophytes favouring scalp hair were called 'trichophilic'. In tinea corporis they form a definite subset, their percentage being similar to that of tinea capitis; A comparison with other studies from this country shows that macroclimate (i.e. humid warm coastal climate compared with dry cooler inland-mountain climate) is not an important factor in the etiology of tinea.

Review of dermatophytoses in Galicia from 1951 to 1987, and comparison with other areas of Spain.
We have reviewed all the dermatophytoses diagnosed in Galicia during four consecutive 9-year periods 1951-86 and 1987. From 4571 patients, we isolated 3351 fungal strains belonging, in decreasing order of frequency, to the following dermatophyte species: Microsporum canis (25.5%), Trichophyton rubrum (24.6%), T. mentagrophytes (21.4%), Epidermophyton floccosum (11.8%), M. gypseum (5.2%), T. tonsurans (3.9%), T. verrucosum (3.1%), T. schoenlenii (2.5%), T. violaceum (1.2%), T. mengninii (0.3%), M. audouinii (0.2%), T. equinum (0.1%) and T. soudanense (0.1%). Tinea capitis has diminished in frequency since 1951, though there was been a slight increase since 1978; M. canis has always been the most common agent, and between 1951 and 1959 T. schoenleinii was also very frequent but is no longer found. The frequency of tinea corporis, on the other hand, has experienced a considerable increase. Its most common causal agents in the last few years have been T. mentagrophytes, M. canis and T. rubrum. Until 1977 the most common tinea cruris dermatophyte was E. floccosum, but since then it has been T. rubrum. The commonest tinea pedis dermatophytes have been T. rubrum and T. mentagrophytes. Tinea unguium and tinea barbae have been the most frequent dermatophytoses, and their commonest causal agents T. rubrum and T. mentagrophytes respectively. We have documented the distribution of the various causal agents by location of the lesions, age and source of the patients (private or National Health Service patients), and we have compared the results with those obtained in other regions of Spain.

Dermatophytoses in Iran.
A total of 12,150 cases of suspected dermatophytoses in different areas of Iran were studied between 1986 and 1991. The age groups most commonly infected were 1-9 and 20-29 years. Clinical diagnosis was confirmed in only 9345 cases by laboratory examination. Of these positive samples, 1633 cases were found to be positive by direct microscopic observation only, 429 by culture only and 7283 by both techniques. Scalp ringworm of children was the most common type of tinea. But according to the rate of infection, tinea corporis, tinea pedis, tinea cruris, tinea manuum, tinea unguium and tinea barbae were the next most prevalent in that order. The frequencies of dermatophytes isolated from patients were as follows: Microsporum canis 19.4%, Trichophyton rubrum 16.5%, Epidermophyton floccosum 14.9%, Trichophyton mentagrophytes var. interdigitale 14.6%, Trichophyton verrucosum 11.5%, Trichophyton mentagrophytes 6%, Trichophyton violaceum 8.7%, Trichophyton schoenleinii 5.5%, Trichophyton tonsurans 1.3%, Trichophyton erinacei 0.8% and Microsporum gallinae 0.2%.

Dermatophytoses in monterrey, méxico.
In the present report we reviewed a total of 2397 cases of dermatophytosis from superficial cutaneous lesions between the years 1978 and 1990. The cases included were from the Department of Dermatology at the University Hospital located in the city of Monterrey, México. A total of 726 tinea pedis, 613 tinea unguium, 441 tinea capitis, 395 tinea corporis and 222 tinea cruris cases were observed. The most commonly isolated dermatophyte species was Trichophyton rubrum (45%), followed by Trichophyton mentagrophytes (23.7%), Trichophyton tonsurans (21%), Microsporum canis (7.1%) and Epidermophyton floccosum (2.5%). Less frequently we isolated Microsporum audouinii, Microsporum gypseum, Trichophyton violaceum and Trichophyton verrucosum. Most of the cases were observed in the warmest months of the year (from March to September), and were equally distributed in both genders, except for tinea cruris which was more prevalent in men (3.5 : 1 ratio).

Dermatophyte agents in the city of São Paulo, from 1992 to 2002.
Dermatophytosis are superficial mycoses caused by fungi that can invade stratum corneum and keratinized tissues. In order to study the frequency of dermatophytes species and the clinical manifestations caused by these fungi, in São Paulo, SP, Brazil, the authors analyzed cultures isolated at the Mycology Laboratory from a selected population (15,300 out-patients of the Hospital das Clínicas, Department of Dermatology, Faculty of Medicine of University of São Paulo) from January 1992 to June 2002. The most prevalent dermatophyte was Trichophyton rubrum (48.7%), followed by Microsporum canis (20.9%), Trichophyton tonsurans (13.8%), Trichophyton mentagrophytes (9.7%), Epidermophyton floccosum (4.1%), and Microsporum gypseum (2.5%). These agents determined more than one clinical manifestation, i.e., tinea corporis (31.5%), tinea capitis (27.5%), tinea unguium (14.8%), tinea cruris (13.9%), tinea pedis (9.9%), and tinea manuum (1.9%). Clinical variants of dermatophytosis and their relationship to the etiologic agents were studied and the results were compared to those obtained in previous studies in other regions of Brazil and in other countries.
