Tinea capitis is a dermatophyte infection common among prepubertal children in sub-Saharan Africa and mainly caused by Trichophyton and Microsporum species. Accurate identification is challenging as conventional methods like culture and microscopy are slow and mostly based on morphological characteristics, which make them less sensitive and specific. Modern molecular methods, like polymerase chain reaction (PCR) assays, are gaining acceptance and are quick as well as accurate. The aim of this study was to investigate the clinical patterns of tinea capitis and to accurately identify the most common causative dermatophytes affecting the scalps of children aged 1 to 16 years attending the Skin Clinic at Mbarara University of Science and Technology (MUST), Mbarara, Uganda, East Africa, using both conventional mycological methods and PCR-ELISA for detection of dermatophyte DNA...

Tinea capitis (TC) is a highly contagious fungal infection of the scalp due to dermatophytes in children. To obtain information on the epidemiology of TC in the urban area of Paris, we analysed the microbiological results of 3090 patients seen with suspected TC from October 2010 to September 2015 at Saint Louis hospital, Paris, France. A peak of TC was observed in 3-6 year-old children, followed by a progressive decrease until 16 years of age. Of the 1311 positive cultures, 95% (1246) yielded one of the three anthropophilic species [Trichophyton tonsurans (33...

Tinea capitis has a high incidence with a global changing pathogen distribution, making this condition a public health concern around the world. As the infection is initially asymptomatic, it is easily spread. Moreover, it is present in many fomites, including hairbrushes, pillows, and bedding. Prompt recognition and treatment is necessary for kerion, an inflammatory subtype characterized by tender boggy plaques with purulent drainage. Kerion is usually associated with infection by zoophilic dermatophytes, although other sources have been described...

Tolnaftate is a thiocarbamate antifungal drug which is therapeutically active against dermatophytes that cause various forms of tinea. Due to the small amount of tolnaftate released from ordinary ointment bases and insufficient penetration through the infected skin layers the need to incorporate the drug in a more suitable pharmaceutical form has evolved. A provesicular system is one such form that can solve these problems. Once in contact with the skin, dilution with moisture occurs and the provesicular system rapidly transforms into a vesicular one...

In the last twenty years, the prevalence of individuals with tattoos in the general population has increased in Europe (1) as well as in Australia (2) and the United States of America (3). A series of complications such as acute inflammatory reactions, allergic contact dermatitis (4,5), photoinduced, lichenoid, and granulomatous reactions (6, 7), pseudolymphoma (8), pseudoepitheliomatous hyperplasia (9), skin infections (6), and skin cancers (10) may occur on tattoos. Infectious complications on tattoos include bacterial infections (pyoderma, leprosy, syphilis, cutaneous tuberculosis, mycobacteriosis) (11-14), viral infections (molluscum contagiosum, warts, herpes simplex, hepatitis B and C) (15-17), and fungal infections (sporotrichosis, dermatophytosis) (18,19)...

BACKGROUND: Impetigo, scabies, and fungal skin infections disproportionately affect populations in resource-limited settings. Evidence for standard treatment of skin infections predominantly stem from hospital-based studies in high-income countries. The evidence for treatment in resource-limited settings is less clear, as studies in these populations may lack randomisation and control groups for cultural, ethical or economic reasons. Likewise, a synthesis of the evidence for public health control within endemic populations is also lacking...

Tinea capitis remains a common childhood infection in many parts of the world. Yet knowledge of the underlying pathogenetic mechanisms and the development of effective immunity have shown striking advances, and new methods of diagnosis ranging from dermoscopy to molecular laboratory tests have been developed even though they have not been assimilated into routine practice in many centres. Treatment is effective although it needs to be given for at least 1 month. What is missing, however, is a systematic approach to control through case ascertainment and therapy...

A 10-year-old girl suffered from tinea corporis with erythematosquamous and centrifugal growing, sparse itching lesions of her right lower arm. Fluorescence optical Blankophor® preparation from skin scrapings revealed fungal hyphae. On Sabouraud's dextrose agar, the fast growing dermatophyte formed flat, peripheral radiating and convolved colonies with white, slightly yellowish to beige brown stained granular and powdery surface. The reverse side of the colonies was smooth with luminous yellow colour. Microscopically, an attitude of thin-walled spindle-shaped and echinulate (with small spins) and lanceolate macroconidia appeared...

A 41-year-old man visited our dermatology clinic because an eruption, which was resistant to steroid ointment treatment, had appeared on his right forearm. An oval, soybean-sized erythematous infiltrated lesion with scales and crusts was located in the central part of the extensor surface of the right forearm and showed partial erosion with attached yellow crusts. The lesion had an impetigo-like appearance. Fungal elements were confirmed from the scales by KOH examination and the fungus was identified as Trichophyton tonsurans by fungal culture and molecular method...

Dermatophytes are responsible for widespread superficial fungal infections, currently representing a real public health problem. Some of the fungi involved in these mycoses are transmitted by pets, illustrating great host specificity within this fungal group. Thus, a new variety of zoophilic dermatophyte has been described in recent years by the Mycology Laboratory of the University Hospital of Nancy, within the complex T. mentagrophytes. This variant was named T. mentagrophytes var. porcellae, following the observation of a significant number of patients with dermatomycoses of exposed parts of the body and having had contact with a guinea pig...
