Fungal infections caused by dermatophytes recently became more common. Available antifungal drugs are limited because of emergence of resistant strains due to prophylaxis with them, so there is an urgent need for novel antifungals. This study is aimed to detect the antifungal activity of silver nanoparticles (SNPs) on Fluconazole resistant dermatophytes isolated from primary school children clinically suffering from tinea capitis and attending El-Sheikh Zaid Dermatology Center in Ismailia. The study was done on 112 clinical cases...

Cutaneous infections and infestations are common among children and adolescents. Ectoparasitic infestations affect individuals across the globe. Head lice, body lice, scabies, and infestations with bed bugs are seen in individuals who reside in both resource poor areas and in developed countries. Superficial cutaneous and mucosal candida occur throughput the life cycle. Dermatophyte infections of keratin-containing skin and skin structures result in tinea capitis (scalp), tinea corporis (body), tinea pedis (foot), and tinea unguium (nails)...

 Affinity of Luliconazole (LLCZ), an antifungal drug used for topical treatment of onychomycosis in Japan, to nail keratin was demonstrated. Efinaconazole (EFCZ) was used as a reference drug. Drugs at fixed concentrations were added to 4 ml of buffer solution containing 40 mg of nail keratin powder prepared from healthy volunteers or from tinea unguium patients. The mixtures were shaken at 37℃, and adsorption and desorption rates of the drug in nail keratin were measured. Theoretical analysis using the Freundlich adsorption isotherm was applied to eliminate effects of testing conditions on the results...

Superficial mycoses are fungal infections restricted to the stratum corneum and to the hair shafts, with no penetration in the epidermis; they are: white piedra, black piedra, tinea versicolor, and tinea nigra. This study presents images of mycological tests performed in the laboratory, as well as exams performed at the authors office, in order to improve the dermatologist's knowledge about the diagnosis of these dermatoses, which are common in many countries.

Deep trichophytosis is relatively uncommon. The infection of the bearded area is also known as sycosis barbae or tinea barbae and can be caused by various fungal species, most often zoophilic fungi. We report on an 80-year-old male patient with severe sycosis barbae who had no animal contact and was treated with systemic antibiosis without improvement. Microbial and mycological investigations using swabs from oozing lesions revealed Staphylococcus hemolyticus and Candida parapsilosis. Histology demonstrated fungal elements in hair follicles...

Microsporum canis is a dermatophyte fungus of which cats and dogs are recognized as the natural hosts. M. canis is also easily transmitted to humans, causing lesions to the glabrous skin (tinea corporis) and to the head (tinea capitis). The present study describes some cases of infection with M. canis in children from a veterinary perspective, highlighting some important features of this clinical entity (e.g., the necessity to identify the animal source of infection with appropriate diagnostic tests; the fact that infected cats may present with no or atypical dermatological signs; and the importance of the environment as a fungal reserve)...

REVIEW

Dermatophytic infection of the skin and its appendages is a common occurrence. Though usually straightforward, treatment of dermatophytosis becomes notably challenging in certain population groups - pregnant women, children, and elderly. Treatment with topical azoles/allylamines alone is effective in limited cutaneous disease in all three groups. Terbinafine is the preferred oral agent in elderly population for treatment of extensive cutaneous disease and onychomycosis due to its lack of cardiac complications and lower propensity for drug interactions...

Among the fungi, dermatophytes are the major cause of spectrum of superficial mycoses medically known as dermatophytosis (tinea) in human and animal. Treatment of these infections has still remained difficult. The aim of this survey was to evaluate in vitro anti-dermatophytic activity of ethanolic extract (EtOH) from Satureja khuzestanica leaf (SKLE) against some clinically important dermatophyte species from the genera of Trichophyton, Microsporum and Epidermophyton. Minimal inhibition concentration (MIC) of SKLE was tested against 14 dermatophyte strains of 5 species by using agar dilution method...

BACKGROUND: Trichophyton equinum is a zoophilic dermatophyte usually causing ringworm in horses. Cases of skin infections in humans are very rare. CASE REPORT : ​We describe a case of tinea corporis caused by T. equinum on a buttock of a rider who often rode bareback with short trousers. CONCLUSION: Although T. equinum was considered in the past as a strict zoophilic dermatophyte, our case report confirms that it can cause dermatophytoses also in humans. A review of epidemiological and clinical features of human infections caused by T...

Microsporum (M.) canis is the most common fungus to cause tinea capitis in Europe, especially in the Mediterranean region and South and Central Europe. Fungal scalp infections caused by M. canis tend to be non-inflammatory. Recently, a growing number of cases of tinea capitis characterized by inflammatory infection caused by M. canis and M. gypseum have been registered. We present a case of highly inflammatory tinea capitis, also known as kerion celsi, caused by M. canis in a 6-year-old-patient. Scalp infections due to M...

Microsporum gypseum complex is a group of geophillic dermatophytes with a worldwide distribution and is a rare cause of dermatomycoses in humans. The infection most commonly presents as tinea corporis, with some geographical and occupational variations. We studied M. gypseum complex infections in patients examined in the Mycological Laboratory of the Department of Dermatovenereology, University Medical Centre Ljubljana, during the period 2000-2015. Diagnosis was confirmed by mycological examination. Skin scales were examined by direct microscopy and cultivated on Sabouraud glucose agar...

Tinea capitis is the most common pediatric superficial dermatophyte infection. The causative species vary, as for instance, Microsporum canis predominates in Europe, while Trichophyton tonsurans predominates in North America. Tinea capitis does not respond well to topical therapy alone, thus oral therapy is requisite. The drug of choice is griseofulvin; however in some countries, it is no longer available. Fungal culture should be requested in the persistent, scalp lesion and trichoscopy can put forward a speedy diagnosis by its characteristic findings...

BACKGROUND: Microsporum gypseum is a geophilic dermatophyte that colonises keratinous substances in the soil. Fur-bearing animals carry this dermatophyte but are rarely infected. Human infection can be acquired from the soil, carrier or infected animals, and rarely other humans. M gypseum is an uncommon cause of cutaneous infection in humans and typically manifests as tinea corporis, tinea barbae, and tinea capitis. Onychomycosis is rarely caused by M gypseum. CASE SUMMARY: We present a case of a 32-year-old white man who presented with a red scaly rash and nail dystrophy after adopting a pet rat 10 years prior to presentation...

Mylabris phalerata (MP) is an insect used in oriental herbal treatments for tumor, tinea infections, and stroke. Recent studies have shown that tumor-associated macrophages (TAM) have detrimental roles such as tumor progression, angiogenesis, and metastasis. Although TAM has phenotypes and characteristics in common with M2-polarized macrophages, M1 macrophages have tumor suppression and immune stimulation effects. Medicines polarizing macrophages to M1 have been suggested to have anticancer effects via the modulation of the tumor microenvironment...
