The association of Yarrowia lipolytica with onychomycosis

mycolabadmin

A 20-year-old woman suffered from a persistent toenail infection that didn’t respond to several standard antifungal treatments over five years. Researchers identified the culprit as Yarrowia lipolytica, a rare yeast not previously known to cause nail infections. Testing showed this yeast was resistant to common antifungal medications the patient had received, explaining why previous treatments failed. This unusual case highlights the importance of properly identifying fungal pathogens and testing them for drug resistance before starting treatment.

A case report of childhood onychomycosis caused by the rare yeast Kodamaea ohmeri

mycolabadmin

A 5-year-old girl in Vietnam developed a nail infection caused by a rare yeast called Kodamaea ohmeri, which typically affects adults with diabetes or weak immune systems. The infection, appearing as white discoloration on the nails, was successfully treated with a topical antifungal cream applied three times daily for one month. This is the first reported case of this rare yeast causing nail infection in a child in Vietnam, and it demonstrates that topical treatment can be effective for fungal nail infections in children whose nails are thinner than adults.

Rasamsonia argillacea brain abscess in a lung transplant recipient: an unexpected infection by an unusual fungal pathogen

mycolabadmin

A 65-year-old woman who received a lung transplant developed a rare and serious brain infection caused by an unusual fungus called Rasamsonia argillacea. The infection was difficult to diagnose because it looks similar to more common molds under the microscope. During the investigation of this unexpected infection, doctors discovered that the patient had a rare genetic disorder affecting her immune system that had never been diagnosed. This case highlights how unusual infections can reveal hidden immune system problems.

Spectrum of Fungal Infections in Continuous Ambulatory Peritoneal Dialysis: A 20-Year Retrospective Study From a Tertiary Care Center

mycolabadmin

This study examined fungal infections in patients undergoing continuous ambulatory peritoneal dialysis (CAPD) over 20 years at an Indian medical center. Researchers found that yeast infections, particularly Candida tropicalis, were more common than mold infections, with Aspergillus flavus being the most frequent mold. The study identified several rare and emerging fungi causing these serious infections and tested their susceptibility to antifungal medications. Results show that removing the dialysis catheter combined with appropriate antifungal treatment is crucial for patient survival.

Increasing incidence of mycotoxicosis in South-Eastern Germany: a comprehensive analysis of mushroom poisonings at a University Medical Center

mycolabadmin

This study examined mushroom poisoning cases in a German hospital from 2005 to 2022 and found that poisonings have nearly doubled in recent years, likely due to more people foraging for wild mushrooms and changes in climate affecting mushroom distribution. The death cap mushroom (Amanita phalloides) caused the majority of serious cases, leading to liver and kidney failure. Researchers found that a blood-cleansing treatment called plasmapheresis could help stabilize patients with life-threatening bleeding complications while they recovered or waited for a liver transplant.

Invasive Cutaneous Mucormycosis in a Patient With Chronic Lymphocytic Leukemia on Obinutuzumab, Idelalisib, and Bruton Tyrosine Kinase Degrader: A Case Report

mycolabadmin

A 74-year-old man with leukemia developed a serious fungal infection (mucormycosis) on his ankle while taking cancer-fighting drugs. The infection was diagnosed through tissue biopsy examination rather than standard culture tests. Treatment required both powerful antifungal medications and surgical removal of the infected leg below the knee. The patient recovered successfully after this aggressive treatment approach.

Cryptococcus albidus (Naganishia albida) meningitis in a young patient with T-cell acute lymphoblastic leukaemia

mycolabadmin

A 16-year-old boy with blood cancer developed meningitis caused by a rare fungus called Cryptococcus albidus. Doctors initially thought he had a viral infection, but laboratory tests identified the fungus. He was treated with antifungal medications and improved significantly. This case shows how important it is to identify the correct cause of infection quickly, especially in patients with weakened immune systems.
