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

mycolabadmin

An 18-year-old boy with acute leukemia developed a serious fungal infection caused by Fusarium mold that spread throughout his body, including to both eyes. Despite receiving intensive antifungal medications injected directly into his eyes along with systemic treatment, he lost his vision. However, through aggressive combined therapy, doctors were able to save both eyes and continue his cancer treatment successfully.

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.

Odontogenic-onset mucormycosis: A case series from a tertiary care institute in North India

mycolabadmin

Mucormycosis is a serious fungal infection that can develop after dental procedures like tooth extraction or root canal therapy, especially in people with poorly controlled diabetes. This case study from India describes five patients who developed this infection within weeks of dental work. The infection destroys bone in the upper jaw and palate but usually doesn’t spread to the sinuses like other forms of mucormycosis. All patients improved with antifungal medications and surgical cleaning, highlighting the importance of proper sterilization during dental procedures.

The first described case of Fomitiporella micropora infection in humans: A heart transplant recipient diagnosed by fungal PCR

mycolabadmin

A patient who received a heart transplant developed a small, slowly-growing lump on his shin over many years. After surgical removal, genetic testing revealed it was caused by a rare fungus never before identified in humans. The surgical removal likely cured the infection, and the case shows how important advanced genetic testing methods are for identifying unusual infections in transplant patients.

Sarocladium implicatum: an unusual agent of opportunistic infection in a COVID-19 patient

mycolabadmin

A 64-year-old man hospitalized with COVID-19 developed a serious fungal infection from Sarocladium implicatum, an unusual fungus rarely found in humans. The infection appeared in his bloodstream and lungs while his immune system was severely weakened by the virus and medications. Doctors identified the fungus using genetic testing and successfully treated him with voriconazole antifungal medication. This case highlights how COVID-19 patients in intensive care are vulnerable to rare opportunistic infections that require specialized laboratory testing to identify and treat.

Roles of the Sec2p Gene in the Growth and Pathogenicity Regulation of Aspergillus fumigatus

mycolabadmin

Researchers studied a gene called Sec2p in a dangerous fungus that causes serious lung infections in people with weak immune systems. By removing this gene, they found the fungus grew slower, caused less damage, and fewer infected mice died. This discovery suggests that blocking Sec2p could be a new way to treat these fungal infections.

Saksenaea oblongispora Rhinosinusitis in Advanced HIV: A Rare and Lethal Mucormycosis

mycolabadmin

A 32-year-old man with advanced HIV developed a severe fungal infection of his sinuses caused by a rare fungus called Saksenaea oblongispora, which typically doesn’t affect people with HIV. The patient presented with severe facial swelling that rapidly worsened, and despite doctors identifying the fungus through biopsies and lab tests, he did not receive antifungal treatment or surgery before his condition became critical. This is the first case of this particular fungal infection documented in sub-Saharan Africa and in HIV patients, highlighting how dangerous this rare infection can be and how challenging it is to diagnose quickly enough to save lives.

A Case Report of Candidiasis Cellulitis in Long-Term Corticosteroid Use

mycolabadmin

A 54-year-old man developed a serious hand infection caused by Candida albicans, a yeast that normally lives harmlessly on human skin. The infection occurred because he had been taking large doses of corticosteroid injections for 15 years to help with breathing problems, which weakened his immune system. Doctors drained the infected area and treated him with antifungal medication, and he recovered completely, highlighting the importance of recognizing fungal infections in patients on long-term steroid therapy.

Co-Infection of Pulmonary Aspergillosis and Cryptococcal Meningitis in an HIV-Positive Patient: A Case Report

mycolabadmin

This case describes a man with undiagnosed HIV who developed two serious fungal infections at the same time: a lung infection caused by Aspergillus fungus and a brain infection caused by Cryptococcus fungus. His extremely low immune system (CD4 count of 41) made him vulnerable to multiple opportunistic infections. Despite treatment with antifungal medications, his condition worsened and he passed away, highlighting the dangers of late HIV diagnosis.

The first report of rhinosinusitis by Rhizopus delemar in a patient with severe COVID-19 in Iran: a case report

mycolabadmin

A 63-year-old man hospitalized with COVID-19 developed a serious fungal sinus infection caused by a rare mold called Rhizopus delemar. Despite surgery to remove infected tissue and treatment with antifungal medication amphotericin B, the infection spread and the patient died after five weeks. This was the first documented case of this particular mold causing sinus infection in a COVID-19 patient in Iran, highlighting how severe fungal infections can occur as dangerous complications of COVID-19.
