Safety and Efficacy of a 48-Month Efinaconazole 10% Solution Treatment/Maintenance Regimen: 24-Month Daily Use Followed by 24-Month Intermittent Use

mycolabadmin

Researchers studied a 4-year treatment plan for toenail fungal infections using efinaconazole, an antifungal solution applied daily for 2 years, then 2-3 times weekly for another 2 years. The treatment was safe and effective, with all patients who achieved a cure maintaining it through the maintenance phase, and even some non-cured patients improving further. The study included many elderly patients, showing the treatment is safe across all age groups and could help prevent infection relapse.

The refractory nailbed ulceration caused by Candida parapsilosis after nail extraction

mycolabadmin

An 82-year-old woman developed a stubborn ulcer on her toenail bed after having the nail surgically removed to treat an infected nail fold. Testing revealed the ulcer was caused by a yeast called Candida parapsilosis, which typically causes infections after physical trauma or injury to the skin. Treatment with an antifungal medication called fluconazole successfully healed the ulcer over three months. This is the first reported case of this specific type of infection following nail removal and highlights the importance of properly identifying the cause of chronic nail infections.

Utility of MALDI-ToF MS for Recognition and Antifungal Susceptibility of Nannizzia, an Underestimated Group of Dermatophytes

mycolabadmin

Nannizzia species are soil-dwelling fungi that increasingly cause stubborn skin, nail, and hair infections in humans and animals. This study tested two laboratory methods for identifying these fungi and measured their sensitivity to eight antifungal drugs. The faster liquid-based method was slightly more accurate (67%) than the traditional culture method (62%), though neither method could identify six very rare species. Terbinafine emerged as the most effective antifungal treatment in laboratory tests.

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

mycolabadmin

This study examined why some fungal nail infections caused by Candida albicans don’t respond to itraconazole treatment. Researchers found that resistant fungi have higher levels of genes that pump the antifungal drug out of their cells and genes that help them form protective biofilm layers. These findings suggest that combining itraconazole with drugs that block these pumps or disrupt biofilms could be more effective for treating stubborn fungal nail infections.

Combination of Q-switched 1,064 and 532 nm Nd: YAG laser in the treatment of toenail onychomycosis: a pilot study

mycolabadmin

This study tested a dual-wavelength laser treatment for toenail fungal infections (onychomycosis) in 15 patients. The laser therapy successfully cured about one-third of patients with mild infections, but was less effective for severe cases. The treatment was safe and well-tolerated, though patients experienced moderate pain during sessions.

PCR enables rapid detection of dermatophytes in practice

mycolabadmin

Researchers in Finland studied how a fast DNA test (PCR) can detect fungal skin infections better than traditional slow culture methods. The new test, called DermaGenius, gives results in just 16 hours instead of 19 days. By 2022, most fungal infection samples were tested using this faster method, which helps doctors treat patients quickly without unnecessary medications.

In vitro characterization of Trichophyton rubrum biofilm by combined anti-biofilm enzymes

mycolabadmin

Athlete’s foot and nail fungal infections caused by Trichophyton rubrum are difficult to treat because the fungus forms protective biofilms that resist antifungal medications. This research shows that enzymes like cellulase, protease, and amylase can break down these biofilm barriers when used alone or in combination. The combination approach was most effective, suggesting that enzyme-based treatments could become useful additions to current fungal infection therapies.

Five-Year Retrospective Analysis of Superficial Fungal Infections: Insights from Hospital Experience

mycolabadmin

This study examined fungal skin infections in over 3,900 patients at a Serbian military hospital over five years. Researchers found that common fungi like Trichophyton mentagrophytes and T. rubrum caused most infections, with patterns varying by season, patient gender, and body location. Men were more likely to have foot infections while women showed more diverse fungal types. The findings suggest doctors should use more precise identification methods like MALDI-TOF testing to prescribe better treatments and help prevent recurring infections.

Schizophyllum commune

mycolabadmin

Schizophyllum commune, commonly known as the split-gill mushroom, is a fungus that grows on wood and was historically considered just a common environmental organism. However, scientists discovered in 1950 that this mushroom could actually infect human tissue, causing conditions like nail infections. This discovery was surprising because mushrooms were not previously known to infect living animals. Today, researchers recognize it as an emerging fungal pathogen that can pose health risks to humans.

Taxonomic revision of Bisifusarium (Nectriaceae)

mycolabadmin

This study provides a comprehensive update on Bisifusarium fungi, a group that includes species used in cheese production and some that can cause human infections. Researchers examined 116 fungal isolates from around the world and identified 25 distinct lineages using DNA analysis. They formally described 8 new species and provided detailed descriptions and photos of previously poorly documented species. This work doubles the known diversity of this fungal genus and will help scientists and medical professionals better identify and understand these fungi.
