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)...

Head and neck cancers, and cardiovascular disease have been described as late effects of low dose radiation (LDR) exposure, namely in tinea capitis cohorts. In addition to radiation dose, gender and younger age at exposure, the genetic background might be involved in the susceptibility to LDR late effects. The -174 G>C (rs1800795) SNP in IL6 has been associated with cancer and cardiovascular disease, nevertheless this association is still controversial. We assessed the association of the IL6-174 G>C SNP with LDR effects such as thyroid carcinoma, basal cell carcinoma and carotid atherosclerosis in the Portuguese tinea capitis cohort...

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...

Clinical distinction between pityriasis amiantacea-like tinea capitis and pityriasis amiantacea due to noninfectious inflammatory diseases is a troublesome task, with a significant likelihood of diagnostic errors/delays and prescription of inappropriate therapies. We report a case of pityriasis amiantacea-like tinea capitis with its dermoscopic findings in order to highlight the usefulness of dermoscopy in improving the recognition of such a condition.

BACKGROUND: Immune reconstitution inflammatory syndrome associated with dermatophytoses (tinea-IRIS) may cause considerable morbidity. Yet, it has been scarcely reported and is rarely considered in the differential diagnosis of HIV associated cutaneous lesions in Africa. If identified, it responds well to antifungals combined with steroids. We present two cases of suspected tinea-immune reconstitution inflammatory syndrome from a large HIV clinic in rural Tanzania. CASES PRESENTATION: A first case was a 33 years-old female newly diagnosed HIV patient with CD4 count of 4 cells/μL (0 %), normal complete blood count, liver and renal function tests was started on co-formulated tenofovir/emtricitabine/efavirenz and prophylactic cotrimoxazole...

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...
