Superficial Fungal Infections in Children—What Do We Know?

mycolabadmin

Fungal infections of the skin, hair, and nails are increasingly common in children worldwide, especially in warm, humid climates and in crowded living conditions. These infections are caused by germs that live on the skin and can spread through contact with infected people or animals. Children are particularly vulnerable due to their developing immune systems, but most infections are treatable with topical creams or oral medications, with terbinafine being the most effective option currently available.

Identification of Non-fumigatus Aspergillus Species in Clinical Samples from Southern California

mycolabadmin

Researchers in Southern California studied fungal infections caused by Aspergillus, a common mold that can infect humans. They found that species other than the traditionally dangerous A. fumigatus are now being detected more frequently in patient samples, particularly from skin and respiratory infections. These non-fumigatus species showed interesting seasonal patterns and some may be resistant to standard antifungal treatments, suggesting doctors may need to adjust their treatment strategies.

Phaeohyphomycosis due to Nigrograna chromolaenae in a cardiac transplant patient

mycolabadmin

A 71-year-old heart transplant patient developed a slowly growing bump on his finger caused by a rare fungus called Nigrograna chromolaenae. Doctors initially tried common antifungal medications that didn’t work well, but the patient improved significantly when switched to posaconazole treatment. This is the first documented case of this particular fungus infecting a human, highlighting the importance of accurately identifying fungi to choose the right treatment.

Etiological Agents and Predisposing Factors of Superficial Fungal Infections in Northeastern Argentina

mycolabadmin

Researchers studied fungal skin infections in a community in northeastern Argentina, finding that 37% of patients had these infections. The most common cause was a fungus called Trichophyton tonsurans. Poor living conditions like overcrowding and lack of clean water increased infection risk. The study shows that fungal skin infections are a significant health problem in areas with limited access to basic sanitation and water services.

Primary cutaneous mixed infection with Cryptococcus uniguttulatus and Mycobacterium tuberculosis

mycolabadmin

A 43-year-old man had a persistent facial rash that didn’t improve with standard antifungal treatments. Doctors initially found a fungal infection called Cryptococcus uniguttulatus using culture tests. However, advanced molecular testing (DNA sequencing) revealed he also had a tuberculosis infection in the same skin lesion. Once both infections were treated with appropriate medications, the patient’s rash finally improved. This case shows that sometimes people can have multiple infections at the same location and that newer diagnostic methods are important for finding these hidden infections.

Usefulness of combining computed tomography and air sac fluid examination to rule out aspergillosis: case study in two gentoo penguins (Pygoscelis papua) with respiratory clinical signs

mycolabadmin

Two penguins at an aquarium showed respiratory problems and were suspected of having a serious fungal infection called aspergillosis. Doctors used CT scans to identify fluid in their air sacs and collected samples for testing. The tests showed the penguins did not have the fungal infection, so they did not need antifungal medications. Both penguins recovered naturally, demonstrating that combining imaging with fluid analysis can help identify the real cause of respiratory problems and avoid unnecessary medication.
