Abstract/Text An epidemiological survey of dermatomycoses and their causative fungus flora in Japan for 2011 was conducted in accordance with methods and criteria of the past four surveys. The survey covered a total number of 36,052 outpatients who visited 12 dermatological clinics throughout Japan. The results were as follows. 1)Dermatophytosis was the most prevalent cutaneous fungal infection (2,980 cases) seen in these clinics, followed by candidiasis (378 cases) and then Malassezia infections (152 cases). 2)Among dermatophytoses, tinea pedis was the most frequent (1,930 cases : male, 980 ; female, 950), then in decreasing order, tinea unguium (780 cases : male, 409 ; female, 371), tinea corporis (203 cases : male, 132 ; female, 71), tinea cruris (112 cases : male, 86 ; female, 26), tinea manuum (43 cases : male, 25 ; female, 18), and tinea capitis including kerion (16 cases : male, 13 ; female, 3). 3)Tinea pedis and tinea unguium were seen to increase in the summer season and occur mostly among the aged population. Compared to the last survey, by clinical form, there was a marked decrease in dermatophytosis patients. 4)As the causative dermatophyte species, Trichophyton rubrum was the most frequently isolated at about 80 % among all dermatophyte infections excluding tinea capitis. T. mentagrophytes was about 10 %. Microsporum canis was isolated in five cases. M. gypseum was isolated in three cases, and Epidermophyton floccosum was isolated in only one case. T. tonsurans was isolated in 13 cases. 5)Cutaneous candidiasis was seen in 378 cases (305, male ; 537, female). Intertrigo (298 cases) was the most frequent clinical form, followed by diaporcandidiasis (79 cases), erosion interdigitalis (62 cases), genital candidiasis (46 cases). 6)Tinea versicolor was seen in 97 cases. Malassezia folliculitis was isolated in 55 cases.

Abstract/Text This is a report of the results of the epidemiological survey on dermatomycoses conducted in 2021. A total of 9,442 patients with dermatomycosis were reported for one year. They include 8,151 (86.3%) with dermatophytosis, 796 (8.4%) with candidiasis, 484 (5.1%) with Malassezia infection, and 11 (0.1%) with deep cutaneous mycosis. In order, the most common types of dermatophytoses were tinea pedis (4,195 cases, 2,341 males and 1,854 females), tinea unguium (2,711 cases, 1,509 males and 1,202 females), tinea corporis (674 cases, 445 males and 229 females), tinea cruris (399 cases, 305 males and 94 females), tinea manus (125 cases, 78 males and 47 females), and tinea capitis (47 cases, 25 males and 22 females). The number of cases of tinea pedis and tinea unguium increased during the summer. A higher percentage of patients were aged 80 or older than in previous surveys. These findings may reflect the increasing percentage of elderly patients seen and the superannuation of the population. As in previous surveys, Trichophyton rubrum and Trichophyton interdigitale were the two most frequently isolated species of fungi causing dermatophytoses. Microsporum canis and Trichophyton tonsurans were the two species most often causing tinea capitis.Regarding cutaneous candidiasis, while candidal intertrigo was the most common in previous surveys, diaper candidiasis in the elderly was the most common in this survey. A background check revealed that this was because a facility included a semi-prophylactic approach to address diaper candidiasis occurring within the ward.Malassezia infections by Malassezia folliculitis clearly increased with each survey. The tendency of certain facilities with many reports of Malassezia folliculitis suggests that it is greatly affected by the presence of physicians familiar with the disease.

A random comparative study of terbinafine versus griseofulvin in patients with tinea capitis in Western China.
Mycopathologia. 2011 Nov;172(5):365-72. doi: 10.1007/s11046-011-9438-2. Epub 2011 Jun 24.
Abstract/Text OBJECTIVE: To compare the efficacy and safety of terbinafine with griseofulvin in the treatment of tinea capitis in Western China.
METHODS: Children (2-14 years of age) with clinically diagnosed and potassium hydroxide microscopy-confirmed tinea capitis were randomized into three groups: group GRI4 received 4 weeks of griseofulvin; group TBF2 received 2 weeks of terbinafine; and Group TBF4 received 4 weeks of terbinafine. Clinical and mycological evaluations were done in 0, 2, 4, and 8 weeks and 1 year after therapy started. The isolated pathogenic fungi were evaluated for in vitro susceptibility by detecting the minimal inhibitory concentration (MIC) against terbinafine, griseofulvin, itraconazole, and ketoconazole.
RESULTS: The clinical effectiveness rate of GRI4, TBF2, and TBF4 were 100% (95% CI-confidence interval: 82-100%), 96.3% (95% CI: 81-100%), and 100%(95% CI: 85-100%), respectively, at week 8 and 100% after 1 year for the 3 groups; clinical cure rates were 84.2%(95% CI: 77-99%), 85.2%(95% CI: 71-98%), and 78.3%(95% CI: 61-95%), respectively, at week 8 and 100% after 1 year for all agents; mycological cure rates were 100%(95% CI: 74-100%), 95.0%(95% CI: 74-100%), and 94.1%(95% CI: 50-93%) at week 8 and 100% after 1 year for the 3 groups. In vitro, all patient-derived cultures were sensitive to the four antifungal agents.
CONCLUSION: Data from the clinical trial and in vitro antifungal activity indicated that terbinafine is efficacious and well tolerated in the treatment for Trichophyton infections (T. violaceum; Arthroderma vanbreuseghemii; and T. tonsurans) of the scalp, i.e., a 2- to 4-week course of terbinafine is as effective as a 4-week course of griseofulvin; in fact, a 2-week course of terbinafine is sufficient. Terbinafine is an effective alternative to griseofulvin against tinea capitis of Trichophyton infections.

Comparison of terbinafine and griseofulvin in the treatment of tinea capitis.
J Am Acad Dermatol. 2000 Jan;42(1 Pt 1):80-4. doi: 10.1016/s0190-9622(00)90013-6.
Abstract/Text BACKGROUND: Griseofulvin has been used for many years in the treatment of tinea capitis. Increase in resistance to this medication has led to a search for new therapeutic alternatives.
OBJECTIVE: Our purpose was to evaluate the therapeutic efficacy of terbinafine in comparison with griseofulvin in the treatment of tinea capitis.
METHODS: We performed a double-blind, randomized, prospective evaluation of 50 patients with a clinical and mycologic diagnosis of tinea capitis. One group received 4 weeks of terbinafine followed by 4 weeks of placebo. The other group received 8 weeks of griseofulvin. We evaluated 5 clinical parameters. Mycologic examinations were performed at baseline and at the end of weeks 8 and 12.
RESULTS: Patients' ages ranged from 1 to 14 years. Fifty-four percent were girls and 46% were boys. Mycologic examinations disclosed Trichophyton tonsurans in 74% of patients and Microsporum canis in 26%. At week 8, the griseofulvin-treated group showed a cure rate of 76%, and the terbinafine-treated group 72%. At week 12, the efficacy of griseofulvin decreased to 44%, whereas the efficacy of terbinafine was 76%.
CONCLUSION: Terbinafine constitutes an alternative for the treatment of tinea capitis. Recurrences were less frequent. No significant side effects were reported.

Therapeutic options for the treatment of tinea capitis caused by Trichophyton species: griseofulvin versus the new oral antifungal agents, terbinafine, itraconazole, and fluconazole.
Pediatr Dermatol. 2001 Sep-Oct;18(5):433-8. doi: 10.1046/j.1525-1470.2001.01978.x.
Abstract/Text Tinea capitis is a relatively common fungal infection of childhood. Griseofulvin has been the mainstay of management. However, newer oral antifungal agents are being used more frequently. A multicenter, prospective, randomized, single-blinded, non-industry-sponsored study was conducted in centers in Canada and South Africa to determine the relative efficacy and safety of griseofulvin, terbinafine, itraconazole, and fluconazole in the treatment of tinea capitis caused by Trichophyton species. The regimens for treating tinea capitis were griseofulvin microsize 20 mg/kg/day x 6 weeks, terbinafine [> 40 kg, one 250 mg tablet; 20-40 kg, 125 mg (half of a 250 mg tablet); < 20 kg, 62.5 mg (one-quarter of a 250 mg tablet)] x 2-3 weeks, itraconazole 5 mg/kg/day x 2-3 weeks, and fluconazole 6 mg/kg/day x 2-3 weeks. Patients were asked to return at weeks 4, 8, and 12 from the start of the study. Griseofulvin was administered for 6 weeks and the final evaluation was at week 12. Terbinafine, itraconazole, and fluconazole were administered for 2 weeks and the patient evaluated 4 weeks from the start of therapy. At this time, if clinically indicated, one extra week of therapy was given. There were 200 patients randomized to four treatment groups (50 in each group). At the final evaluation at week 12, the number of evaluable patients were griseofulvin, 46; terbinafine, 48; itraconazole, 46; and fluconazole, 46. Patients who discontinued therapy or were lost to follow-up were griseofulvin, 1/3; itraconazole, 0/4; terbinafine, 0/4; and fluconazole, 0/4. The causative organisms were Trichophyton tonsurans and T. violaceum species. Patients were regarded as effectively treated at week 12 if there was mycologic cure and either clinical cure or only a few residual symptoms. Effective treatment was recorded in, intention to treat, griseofulvin (46 of 50, 92.0%), terbinafine (47 of 50, 94.0%), itraconazole (43 of 50, 86.0%), and fluconazole (42 of 50, 84.0%) (p=0.33). Adverse effects were reported only in the griseofulvin group (gastrointestinal effects in six patients). Discontinuation from therapy due to adverse effects occurred only in the griseofulvin group (nausea in one patient). For the treatment of tinea capitis caused by the Trichophyton species, in this study, griseofulvin given for 6 weeks is similar in efficacy to terbinafine, itraconazole, and fluconazole given for 2-3 weeks. Each of the agents has a favorable adverse-effects profile.

Itraconazole versus griseofulvin in the treatment of tinea capitis: a double-blind randomized study in children.
Int J Dermatol. 1994 Oct;33(10):743-7. doi: 10.1111/j.1365-4362.1994.tb01525.x.
Abstract/Text BACKGROUND: Tinea capitis is a fungal infection in which topical therapy is often unsuccessful. Griseofulvin has been considered to be a first-line therapy. Other antifungal agents are the azole derivatives. Among these, itraconazole was compared with griseofulvin in children in a double-blind study.
PATIENTS AND METHODS: Thirty-four children and one adult with clinical signs and symptoms of tinea capitis and with positive culture and microscopy for dermatophytes have been included in a double-blind comparison between itraconazole, 100 mg daily, and ultramicronized griseofulvin, 500 mg daily. Both drugs were given for 6 consecutive weeks. The final evaluation was made 8 weeks after the end of treatment to allow the hairs to regrow. Seventeen itraconazole- and 15 griseofulvin-treated patients received the complete 6-week treatment course. Fifteen of these 17 itraconazole patients and 14 of the 15 griseofulvin patients had infections caused by Microsporum canis. Fifteen of 17 patients were cured by itraconazole (88%) and 15 of 17 patients by griseofulvin (88%). One of the patients who discontinued griseofulvin therapy after 4 weeks was clinically and mycologically cured. Two of the original 17 griseofulvin patients discontinued therapy because of vomiting. None of the itraconazole-treated children experienced side effects.
CONCLUSIONS: Itraconazole is the first azole derivate that matches griseofulvin for the treatment of tinea capitis in children. The drug also appears to be better tolerated than griseofulvin.

A double-blind, randomized, comparative trial of itraconazole versus terbinafine for 2 weeks in tinea capitis.
Br J Dermatol. 1998 Oct;139(4):672-4. doi: 10.1046/j.1365-2133.1998.02465.x.
Abstract/Text In this randomized, double-blind study, the efficacy and safety of oral itraconazole (n = 28) and terbinafine (n = 27), each given for 2 weeks, was compared in patients with tinea capitis. Trichophyton violaceum was the major pathogen in both groups (82.1% and 88.9%, respectively). The final evaluation at week 12 showed a cure rate of 85.7% and 77.8%, respectively (P > 0.05). Adverse events noted were mild and did not warrant discontinuation of therapy.

Treatment of kerions.
Pediatr Dermatol. 1994 Mar;11(1):69-71. doi: 10.1111/j.1525-1470.1994.tb00079.x.
Abstract/Text Therapy for kerions was evaluated by randomly assigning 30 patients to one of four treatment groups: group A griseofulvin, group B griseofulvin plus erythromycin, group C griseofulvin plus prednisone, and group D griseofulvin, erythromycin, and prednisone. Data indicate that antibiotic and steroid therapy, in addition to griseofulvin, may reduce scaling and pruritus, but does not reduce the time it takes for kerions to flatten.

A randomized, comparative trial of treatment of kerion celsi with griseofulvin plus oral prednisolone vs. griseofulvin alone.
Med Mycol. 1999 Apr;37(2):97-9.
Abstract/Text Glucocorticoids are often recommended along with oral antifungals in the treatment of kerion celsi. In this randomized study, the efficacy of combination therapy with oral griseofulvin and oral prednisolone (n =17) was compared to oral griseofulvin alone (n=13) in the treatment of kerion celsi. Both groups were treated with oral griseofulvin for 8 weeks whereas oral prednisolone was given in tapering doses for 3-4 weeks to the first group only. The final evaluation at week 12 showed a cure rate of 100% in both groups without any significant difference in terms of clinical or mycological cure (P>0.05). No adverse events were noted in either group. In our opinion the combination of oral prednisolone with griseofulvin does not result in additional objective or subjective improvement compared to griseofulvin alone in cases with kerion celsi.
