INTRODUCTION: White piedra is a superficial mycosis caused by the genus Trichosporon and characterized by nodules on hair shaft. METHODS: The authors report a family referred to as pediculosis. Mycological culture on Mycosel® plus molecular identification was performed to precisely identify the etiology. RESULTS: A Trichosporon spp. infection was revealed. The molecular procedure identified the agent as Trichosporon inkin. CONCLUSIONS: White piedra and infection caused by T. inkin are rarely reported in Southern Brazil. The molecular tools are essentials on identifying the Trichosporon species.

White piedra is a superficial mycosis caused by the genus Trichosporon. It is characterized by nodules on the hair shaft. Pediculosis capitis is caused by Pediculus humanus var. capitis of the suborder Anoplura. Whereas pediculosis is a common infestation, clinical reports of white piedra are rare. Molecular biology procedures identified T. inkin as the agent of white piedra in this case report. The authors present associations between the two diseases in the same patient in order to highlight their clinical differences.

White piedra is a superficial mycosis caused by Trichosporon spp. that affects the hair shaft of any part of the body. It is presented an outbreak of scalp white piedra seen in 5.8% of the children frequenting a day care in Northeastern of São Paulo State, Brazil. Mycological exam and culture identified T. cutaneum in all five cases, and scanning electron microscopy of nodules around hair shaft infected by Trichosporon spp. is demonstrated comparing them with those of black piedra and with nits of Pediculous capitis.

Recent years, due to increased usage of antifungal treatment worldwide, there is an increased chance of rising resistance among antifungal drugs too. Dermatophytic infections causes’ superficial mycosis and it affects skin, hair and nail. These infections are more common and antifungal drugs are used everywhere to treat those common infections. To conduct a study by determining the antifungal susceptibility pattern in dermatophytic isolates from patients attending dermatology OPD in a tertiary care hospital. A total of 217 samples like hair, nail and skin scrapings were obtained and isolation of dermatophytes was done. Antifungal susceptibility testing for dermatophytes was performed by micro broth dilution method. Antifungal drugs tested were Griseofulvin, Fluconazole, Itraconazole and Ketoconazole. Minimum inhibitory concentration for each drug for fungal isolates was tested and results studied. Fluconazole showed a higher MIC values in the range of 1-8µg/ml. Itraconazole showed the lowest MIC values by micro broth dilution method. Since there is limitation of standard guidelines and protocol, meticulous research must be conducted on effect of antifungals and derive at universally implementable guidelines.

Background-Superficial Mycosis, which is the most common fungal infection affecting human beings, includes Dermatophytosis and Dermatomycoses, which are the infections of superficial keratinized layer of skin, nail & hair by Dermatophytes and non Dermatophytic moulds or yeasts respectively. This clinical entity is very common in hot, humid tropical climate of India with prevalence ranging from 30-60% but its precise case magnitude and epidemiology in North eastern India cannot be stated as there are only few studies conducted. So, this study is undertaken to 1) Find the prevalence of Superficial Mycosis in a tertiary health care centre of Southern Assam. 2) Study the clinical profile of the cases 3) Isolate and identify the causative agents of Superficial mycosis. Materials & Method- The study has been conducted on 250 samples from clinically suspected and untreated cases of superficial mycosis from Aug 2017 to Dec 2018. 2 separate sets of samples from edge of skin lesion/nail /hair were collected, of which 1 sample was subjected to direct microscopy with (10-40) % KOH and the other part was subjected to 2 sets of fungal culture in SDA tubes at 25°C and 37°C & followed for 3 weeks. In Culture positive cases, fungal identification was based on colony morphology, pigment production & LPCB mount. For confirmation of isolates, Slide Culture and biochemical tests were done. Result-Out of total 250 samples,115 samples (46%) showed presence of fungal elements in KOH examination, of which 73 were culture positive and of the KOH negative samples 10 samples were culture positive, thus making the prevalence 33.2% (83/250). Clinically, Tinea corporis was the most common form of both superficial mycosis & Dermatophytosis and Pityriasis Versicolor has been found the most common Dermatomycosis. Males(21-50yrs) were affected by superficial mycosis more than Females(16-30yr). Trichophyton mentagrophyte was the mostly isolated agent causing superficial mycosis.

Background Superficial mycoses is a fungal infection of the skin, nails and hair thatcaused by dematophytes, yeast and mold. Superficial mycoses infections are commonlyfound in high temperature and humidity area such as Indonesia. Palembang is one ofregions in Indonesia has a high temperature and humidity, considered the incidenceof this disease is high. A retrospective study of new cases of superficial mycoses, datataken from medical records and register book at Policlinic of Dermatology andVenereology Dr. Moh. Hoesin Palembang during 5 years from January 2014-December2018. There were 1,236 (17.1%) new cases of superficial mycoses. Incidence ofsuperficial mycoses varies with range 6.9%-23%. The most common superficialmycoses is dermatophytes (38,3%). Microsporum canis, Trichophyton rubrum danTricophyton hmentagrophytes are frequent isolates in this study. The most age groupis 36-45 years (17.6%) with male more than female. Superficial mycoses are often foundin students (26.9%), followed by unskilled workers (20.8%). Of the 1,236 new cases,125 patients had comorbidities, such as malignancy 21 (16.8%) patients,cerebrovascular disease and diabetes mellitus each 16 patients (7.4%). Inguinal andabdomen are the most commonly infected regions. 656 (53.1%) patients was giventopical antifungal. The most common topical antifungal was ketoconazole 2% cream(62%) and systemic antifungal was itraconazole (55,3%).Conclusion: Cases ofsuperficial mycoses, especially dermatophytosis and Malassezia were still commonlyfound, especially in Palembang.

Superficial Mycosis

Background and Purpose: Superficial mycosis is more prevalent in tropical and subtropical countries, such as India. Regarding this, the present study was conducted to determine the epidemiology of superficial mycosis and identify the most common dermatophytic species in this region. Materials and Methods: For the purpose of the study, a total of 220 skin scraping, nail, and hair root specimens were collected. Direct microscopic examination was performed using potassium hydroxide mount. Additionally, the samples were inoculated onto Sabouraud dextrose agar (SDA) and dermatophyte test medium (DTM). The fungal colony of each isolates was stained with lactophenol cotton blue mount, and observed under microscope for species identification. Results: Out of 220 isolates, 172 samples, obtained from 108 males 64 females, were positive for skin fungal infections by either KOH mount or culture. Furthermore, 113 isolates were identified as dermatophytes, while 59 samples were found to be non-dermatophytes. Among the dermatophytes isolated from different clinical samples, Trichophyton verrucosum (42/113, 38%) was the most common species, and Tinea corporis was the most common infection (36.2%). Conclusion: As the findings indicated, dermatophytes had an isolation rate of 78%, which is higher than normal. This can be due to the fact that the majority of the patients were from a rural background (71.7%) with a low socioeconomic status and poor personal hygiene who were exposed to climatic changes.
