A case report of disseminated histoplasmosis not responding to primary treatment by itraconazole

mycolabadmin

A 28-year-old woman developed a fungal infection called histoplasmosis after having a tooth extracted, with the infection spreading to her lungs and sinuses. She was initially given a common antifungal medication called itraconazole, but her condition continued to worsen despite increasing the dose. When doctors switched her to a stronger medication called liposomal amphotericin B given intravenously, she improved dramatically and recovered fully. This case shows the importance of recognizing when a standard fungal treatment is not working and switching to more aggressive therapy.

Endogenous Endophthalmitis: An underestimated serious complication in patients with disseminated fusariosis

An 18-year-old leukemia patient developed a serious fungal eye infection from Fusarium during cancer treatment. The infection spread through the bloodstream to both eyes, causing serious inflammation and vision loss. Doctors treated it with multiple antifungal medications injected directly into the eyes along with systemic medication, which controlled the infection but unfortunately the patient’s vision was significantly affected. This case highlights how rare but serious eye infections can occur in cancer patients with weakened immune systems.

Traumatic implantation keratitis caused by Schizophyllum commune in Central India

This report describes two patients in India who developed serious fungal eye infections (keratitis) after corneal injuries. The infection was caused by Schizophyllum commune, a mushroom-like fungus found on decaying wood. Despite aggressive treatment with antifungal medications and surgery, both patients lost vision in their affected eyes. The case highlights how difficult it is to identify and treat this rare fungus.

Pathogenic mucorales: Deciphering their cell wall polysaccharidome and immunostimulatory potential

Mucormycosis is a dangerous fungal infection that kills many immunocompromised patients. Researchers analyzed the outer layer (cell wall) of three common disease-causing fungi and discovered that their surfaces contain sugar-like molecules that trigger strong inflammatory responses from the immune system. This excessive inflammation may actually contribute to the disease’s severity, suggesting that controlling inflammation alongside antifungal treatment might improve patient outcomes.

Dermatophytosis in a Chilean fox: first case of Nannizzia gypsea in Lycalopex griseus and the need for a one health approach

mycolabadmin

Researchers reported the first case of a fungal skin infection caused by Nannizzia gypsea in a wild South American grey fox found near Santiago, Chile. The fox developed crusted and scaly lesions on its tail, which were successfully treated with topical antifungal cream. This discovery highlights how increasing contact between domestic pets, wild animals, and humans due to urbanization can spread fungal infections, emphasizing the need for integrated health approaches that consider human, animal, and environmental health together.

A rare case of invasive necrotizing myositis of the thigh caused by Basidiobolus ranarum: a multi-pronged approach to successfully managing a near-fatal polybacterial mycotic infection

mycolabadmin

A 46-year-old man developed a severe fungal infection of his thigh caused by Basidiobolus ranarum, a rare fungus found in soil and animal feces. The infection worsened with secondary bacterial contamination, leading to tissue death and eventually requiring amputation. Doctors successfully treated the infection using a combination approach: antifungal medications (voriconazole and potassium iodide), antibiotics, and multiple surgical cleanings, though earlier treatment would have saved his limb.

Photo Quiz: A cutaneous fungal infection with discordant biomarker results—a diagnostic challenge

mycolabadmin

A woman with advanced HIV infection presented with skin sores and respiratory symptoms that were initially suspected to be a viral infection. Testing revealed she had histoplasmosis, a serious fungal infection caused by Histoplasma capsulatum that had spread throughout her body affecting her skin, lungs, and lymph nodes. While standard tests for this fungus were negative, other fungal markers and cultures eventually confirmed the diagnosis, and she was treated with antifungal medications.

Invasive Rhinocerebral Mucormycosis Is a Rare Complication in Systemic Juvenile Idiopathic Arthritis Patient

mycolabadmin

A 5-year-old girl with systemic juvenile arthritis being treated with immunosuppressive medications developed a rare and serious fungal infection in her nose and sinuses caused by a mold called Lichtheimia. The infection caused tissue death and spread toward her brain, but was successfully treated with combination antifungal drugs and surgery. This case highlights how powerful immunosuppressive treatments for severe arthritis can increase the risk of life-threatening fungal infections.

mGem: Submarine mycology—an analog to astromycology

mycolabadmin

Scientists are studying fungi in submarines to better understand fungal health risks for astronauts in space. Both submarines and spacecraft are enclosed environments where fungi can grow, causing infections and other health problems. The same types of fungi found growing in submarines have been detected on the International Space Station. By learning from decades of submarine research, space agencies can better prepare for and prevent fungal-related health issues during long space missions.

Clinical, Laboratory, and Biomarker Predictors of 90-Day Mortality in Non-HIV, Non-Transplant Pneumocystis Pneumonia

mycolabadmin

This study examined pneumocystis pneumonia in immunocompromised patients who do not have HIV or transplants. Researchers found that older patients with other health conditions were at higher risk of death within 90 days. High levels of fungal markers and low immune cell counts were better predictors of poor outcomes than traditional inflammation markers, suggesting doctors should focus on early identification and personalized treatment approaches.
