Experimental research on fungal inhibition using dissolving microneedles of terbinafine hydrochloride nanoemulsion for beta-1,3-glucanase

mycolabadmin

Researchers developed a new patch treatment for nail fungus using tiny dissolving needles that deliver antifungal medication directly into the skin near infected nails. The patch combines two active ingredients that work together to kill fungus and break down protective biofilm layers that make fungal infections hard to treat. Testing showed the patch was safe, effective, and delivered much more medication to the infected area compared to traditional creams or pills.

Molecular identification of yeast communities isolated from nail specimens by PCR-RFLP and PCR-FSP methods

mycolabadmin

This study developed and compared two molecular methods to accurately identify different yeast species that cause nail infections. Researchers tested 269 patient samples and found that both PCR-RFLP and PCR-FSP methods were effective, with PCR-FSP being better at identifying rare yeast species. These methods help doctors identify the exact type of yeast causing infection, which is important for selecting the right antifungal medication for treatment.

Overexpression of efflux pump and biofilm associated genes in itraconazole resistant Candida albicans isolates causing onychomycosis

mycolabadmin

Nail fungal infections caused by Candida albicans can be difficult to treat when the fungus becomes resistant to common antifungal medications like itraconazole. Researchers found that resistant strains have overactive genes that pump the drug out of fungal cells and genes that help the fungus form protective biofilm structures. Understanding these resistance mechanisms could lead to better combination treatments that block these protective strategies.

Two Cases of Fungal Melanonychia

mycolabadmin

Two patients developed dark pigmentation on their toenails caused by rare combinations of fungal infections. Through laboratory testing and genetic analysis, doctors identified fungi never before known to cause this type of nail discoloration. Both patients were successfully treated with an antifungal medication called efinaconazole, with complete resolution of symptoms within a few months.

Epidemiology of Onychomycosis in the United States Characterized Using Molecular Methods, 2015–2024

mycolabadmin

This large study examined over 710,000 nail samples to identify which fungi cause nail infections in the United States. Using modern molecular testing combined with microscopic analysis, researchers found that while the fungus T. rubrum is most common, other molds and yeasts cause many infections too. Importantly, women and older adults are more likely to have infections from these other organisms, which are often harder to treat with standard antifungal medications.

Onychomycosis in the US Pediatric Population—An Emphasis on Fusarium Onychomycosis

mycolabadmin

This study examined nail fungus infections in American children using advanced molecular testing. Researchers found that elementary school-aged children (ages 6-11) have the highest rates of nail fungus, usually caused by common fungi like Trichophyton rubrum. Notably, Fusarium, an environmental fungus that was once rare in nail infections, is becoming increasingly common, especially in older teenagers, which may require different treatment approaches.

Superficial Fungal Infections in Children—What Do We Know?

mycolabadmin

Superficial fungal infections like ringworm and athlete’s foot are common in children and are caused by fungi, yeasts, or molds that spread through contact with infected people, animals, or contaminated surfaces. These infections primarily affect the scalp, skin, and nails, with scalp infections being most common in young children. Treatment typically uses topical creams for mild cases or oral medications for more severe infections, particularly those affecting nails or the scalp. Proper hygiene, avoiding contaminated areas, and limiting contact with infected individuals or animals are key to prevention.

Two Cases of Fungal Melanonychia

mycolabadmin

This paper describes two unusual cases where fungal infections of the toenails caused dark pigmentation (melanonychia). The first patient had a combination of two fungi (Aspergillus hiratsukae and Trichosporon faecale) causing black nail streaks, while the second had Exophiala xenobiotica and Trichophyton interdigitale causing dark-brown discoloration. Both patients were successfully treated with an antifungal medication called efinaconazole over several months.

Clinico-mycological study of superficial mycoses and correlation with anti-fungal susceptibility among the Candida isolates in a teaching institution of Western India

mycolabadmin

This study examined fungal skin infections in 330 patients in Western India, identifying which fungi cause these infections and which antifungal drugs work best. Researchers found that Candida yeasts were especially common in nail infections while Trichophyton fungi were more common in skin infections. The antifungal drug caspofungin was most effective against Candida, while the commonly used drug fluconazole showed increasing resistance.

The association of Yarrowia lipolytica with onychomycosis

mycolabadmin

A 20-year-old woman had a persistent toenail infection that did not respond to multiple antifungal treatments. Researchers identified the cause as Yarrowia lipolytica, an unusual yeast that had never been found causing nail infections before. The yeast was resistant to several common antifungal medications, explaining why previous treatments failed. This case shows the importance of identifying the exact fungus causing an infection to develop effective treatment strategies.
