Tinea Capitis in Adults

Objective: To determine the epidemiology and the aetiology of tinea capitis in the elderly in Turin (Italy). Methods: We prospectively collected all cases of adult tinea capitis in the Dermatology Clinic of the University of Turin from January 1997 to December 2012. Results: 13 patients (4 males and 9 females) with a mean age of 56.5 years were found to be affected by tinea capitis among a total number of 508 (2.6%). Diagnosis was made on clinical appearance and mycological examination. Culture identified M. canis in 7 patients (53.8%), T. mentagrophytes in 3 patients (23.1%), T. rubrum in 2 patients (15.4%) and T. violaceum in 1 patient (7.7%). 6 cases reported contact with animals. Treatment consisted in administration of Griseofulvin at the dose of 500 mg/d or Terbinafine at the dose of 250 mg/d for at least 8 weeks. A complete recovery was observed in 10 patients, whereas 3 of them suffered from cicatritial alopecia. Conclusion: This study wants to highlight the importance of considering tinea capitis as a differential diagnosis in elderly patients with scaly scalp lesions, even though it is considered to be rare in adults.

New Thai herbal shampoos as pediculicides for killing head louse, Pediculus humanus capitis De Geer(Phthiraptera)

Objective: To evaluate the efficacy of Thai herbal shampoos [Cartoxylum formosum(C.formosum) + eucalyptus essential oil(EO), C. formosum + citrus EO, Solanum trilobatum+ eucalyptus EO, Solanum trilobatum + citrus EO, Moringa oleifera + eucalyptus EO and Moringa oleifera + citrus EO] for killing all stages of Pediculus humanus capitis(Phthiraptera).Methods: A filter paper contact method was applied with three concentrations(0.05, 0.10 and 0.20 mL/cm^2) of each Thai herbal shampoo as well as permethrin pediculicide(positive control) and drinking water(negative control) against eggs, nymphs and adults of Pediculus humanus capitis. Mortality rates of the eggs were recorded after 7 days of incubation while those of nymphs and adults were recorded after 5 minutes of contact. Results: All herbal shampoos at the high concentration were highly effective against nymphs and adults, but not effective against the eggs. C. formosum + eucalyptus EO and C. formosum + citrus EO shampoos at all concentrations exhibited the highest efficacy against nymphs and adults with100% mortality rate at 5 min and LC_(50) values of 0.004 and 0.005 mL/cm^2, respectively. All formulation of Solanum trilobatum and Moringa oleifera shampoos added with eucalyptus EO showed mortality rates against nymphs at 92.0%-100.0% and 76.0%-100.0% and against adults at 84.0%-100.0% and 20.0%-32.0%, respectively. Permethrin pediculicide was not effective against the eggs, but showed 68.0%-92.0% and 28.0%-60.0% mortality rates against nymphs and adults. Conclusions: These results indicate that C. formosum + eucalyptus EO shampoo can be used as an effective nymphicide and adulticide against Pediculus humanus capitis.

Tinea incognito due tomicrosporum gypseum

A 41-year-old woman presented with a pruritic rash on the face that was of 3 months duration. During that time, it had been successively misdiagnosed as psoriasis vulgaris, systemic lupus erythematosus, facial dermatitis at other hospitals, and had been treated with agents that included acitretin and prednisone. Finally, fungi were found in the lesions by optical microscopy, and the fungal culture was positive for Microsporum gypseum, and was diagnosed as a Microsporum gypseum infection. The lesions eventually cleared completely after 8 weeks of antifungal treatment.

Inflammatory Tinea Manuum due to <i>Trichophyton erinacei</i>from an African Hedgehog

The zoophylic dermatophytes, as Trichophyton erinacei, frequently cause very inflammatory tineas in the human host. This dermatophyte is carried by some pets, particularly by the terrestrial hedgehog. Herein, we present the case of a 22-year-old male student with an exudative erythematous scaly plaque on his right fifth finger for 1 month. He had a pet African hedgehog (Atelerix albiventris). KOH examination demonstrated hyphae compatible with dermatophytes. The culture revealed a white, radiated dusty colony. PCR sequencing of the region ITS1-5.8S-ITS2 identified T. erinacei. The final diagnosis was inflammatory tinea manuum due to T. erinacei. Clinical and mycological cure was achieved after treatment with oral terbinafine 250 mg/day × 1 month.

Ginkgo paste improves tinea corporis in a guinea pig model

To investigate the effects of Ginkgo paste for external use on tinea corporis in a guinea pig model.The guinea pig tinea corporis model were induced by infection with Trichophyton mentagrophytes strains.And then,high and low doses of Ginkgo water-paste and alcohol-paste were administrated to the animals.The symptom,tinea corporis skin lesions and histopathological aspects of guinea pig were analyzed.High and low doses of Ginkgo alcohol-paste and Ginkgo water-paste could significantly reduced the tinea corporis symptom(P<0.01),increased negative rate of strain culture(P<0.01),and improved pathological changes of tinea corporis(P<0.01).The best efficacy was observed in high dose ginkgo alcohol paste group.These results suggest that Ginkgo paste exhibits the efficacy to treat tinea corporis in a guinea pig model.

Topical 5-aminolevulinic acid photodynamic therapy improved refractory acne conglobata and perifolliculitis capitis abscedens et suffodiens rather than hidradenitis suppurativa

Acne conglobata(AC),perifolliculitis capitis abscedens et suffodiens(PCAS)and hidradenitis suppurativa(HS)are uncommon refractory chronic,inflammatory,scarring diseases but cause serious damage to the quality of life.These three diseases are associated with follicular occlusion.Several studies indicated topical 5-aminolevulinic acid photodynamic therapy(ALA-PDT)improved follicular occlusion besides acne treatment.So we attempted to apply ALA-PDT to medicine resistant AC,PCAS and HS.Topical ALA-PDT was applied to 10 patients with AC,seven patients with PCAS and three patients with HS for more than three sessions.All the patients completed the dermatology life quality index(DLQI)questionnaire and were assessed for the efficacy at the baseline and on two weeks after each treatment.Adverse effects were recorded at each visit.The results showed 25.5%(5/20,two cases of AC and three cases of PCAS)of patients achieved excellent improvement after three sessions of PDT and another 60.0%(12/20,eight cases of AC and four cases of PCAS)of patients achieved good improvement.15.0%(3/20,three cases of HS)got poor response(<20%lesions clearance).Anotherfive cases(three cases of AC and two cases of PCAS)also achieved excellent response after 5–7 sessions of PDT.We also found that papular/nodular,cyst/abscess showed higher clearance rate than sinus/¯stula(88.5%,86.1%versus 11.1%).DLQI was reduced after three sessions of PDT in AC and PCAS patients rather than HS patients.5-ALA-PDT could improve refractory AC and PCAS but could not lead to improvement in late stage of HS.The e±cacy increased with more treatment sessions.

A Prospective Single-Arm Investigation Assessing Performance of a Multifunctional Foot Cream in Subjects with Tinea Pedis Interdigitalis and Heel Cracks, Calluses and/or Dry Feet

This prospective, open-label, single-arm investigation evaluated the performance of a multifunctional foot cream used twice daily for 8 weeks in the combined treatment of mild/moderate tinea pedis interdigitalis (TPI) and heel cracks, calluses and/or dry feet in 46 adult subjects. All subjects showed reductions in the severity of symptoms of both TPI (53.7% reduction) and heel cracks, calluses and/or dry feet (51.6% reduction), beginning already after 2 weeks of treatment, with reduction continuation and improvement after 4 and 8 weeks of treatment. Negative mycological cultures were obtained post-treatment in 85.7% of subjects, while 35.7% of subjects also obtained mycological cure (negative mycological culture + negative KOH test). Post-treatment questionnaires showed improved quality of life, good treatment tolerability, easy use, and that 69% of subjects would recommend the product. The results reveal that the foot cream is safe and effective in the combined treatment of TPI and heel cracks, calluses and/or dry feet.

Tinea of Vellus Hair Caused by Trichophyton violaceum in a Child:A Case Report

Introduction:Tinea of vellus hair is a rare dermatophytosis,caused by dermatophyte infection in the vellus hair.The clinical symptoms of tinea of vellus hair are more serious and the conventional topical treatment are often ineffective.Here,we report a case of tinea of vellus hair caused by Trichophyton violaceum in a child.Case presentation:A 7-year-old boy presented with a localized,scaly,and itchy erythema on his left cheek for two months.He once used a topical corticosteroid but without any clinical improvement,the erythema was progressively enlarging and spread to the left eyebrow.He denied any contact with animals.Direct microscopy found abundant spores and hyphae on the vellus hair;T.violaceum was identified by culture and PCR examination.The patient was diagnosed with tinea of vellus hair and cured after treating with oral terbinafine 125 mg/day and topical treatment for two weeks.There was no recurrence during the follow-up period.Discussion:The clinical symptoms of tinea of vellus hair are often atypical and easy to be misdiagnosed.Timely fungal examination is necessary for suspicious patients and confirmed patients should be treated with oral antifungal drugs.Conclusion:The diagnosis and treatment of tinea of vellus hair need to be paid more attention in clinical works.
