Aspergillus empyema is usually reported as a complication of surgical procedures, and spontaneous cases are quite rare. Here, we describe the case of a 16-year-old man who suddenly developed dyspnea despite previously being healthy. Chest computed tomography showed multiple mass-containing cavity lesions, pneumothorax, and pleural effusion in the left thorax. Within 2 weeks, Aspergillus fumigatus grew from his pleural effusion, thus he was diagnosed with Aspergillus empyema. He also developed severe eosinophilia after admission, and was treated with anti-fungal drugs...

BACKGROUND: Fusarium species are widely spread in nature as plant pathogens but are also able to cause opportunistic fungal infections in humans. We report a cluster of Fusarium oxysporum bloodstream infections in a single pediatric cancer center. METHODS: All clinical and epidemiological data related to an outbreak involving seven cases of fungemia by Fusarium oxysporum during October 2013 and February 2014 were analysed. All cultured isolates (n = 14) were identified to species level by sequencing of the TEF1 and RPB2 genes...

Improved understanding of basic mycological, pharmacological, and immunological processes has led to important advances in the diagnosis and treatment of invasive fungal infections. However, the rise of fungi that are resistant to existing antifungal agents poses a substantial threat to human health. Addressing this expanding problem is an urgent priority for the international research community. In this article, we highlight important diagnostic and therapeutic advances that address the rise of resistant fungi as well as new public health initiatives that warrant further investigation to help curb the spread of these potentially lethal organisms...

Mucormycosis is a rare potentially fatal opportunistic fungal infection that affects human beings. Normally, a healthy is immune to such infections but there are some risk factors which predispose a person to mucormycosis, of which malnutrition and diabetes mellitus are the most common risk factors. India is the most commonly affected country by mucormycosis because of high proportion people with low socioeconomic status and diabetes mellitus. In diabetes mellitus, mucormycosis is more aggressive and fatal due to an impaired host defense mechanism...

Although uncommon in children, fungal infections of the central nervous system can be devastating and difficult to treat. A better understanding of basic mycologic, immunologic, and pharmacologic processes has led to important advances in the diagnosis and management of these diseases, but their mortality rates remain unacceptably high. In this focused review, we examine the epidemiology and clinical features of the most common fungal pathogens of the central nervous system in children and explore recent advances in diagnosis and antifungal therapy...

Primary pulmonary angiosarcoma is extremely rare. It is often characterized by a clinically indolent course and delayed diagnosis. To date, there have been <20 cases reported. By far, little article correlates the clinical presentation, the imaging findings with the pathology. The authors present a case of middle-aged gentleman with primary pulmonary epithelioid angiosacroma which we initially thought as tuberculosis (TB) infection. A 60-year-old gentleman, with a history of 6 months on and off blood stained sputum, was admitted for an episode of massive hemoptysis...

The immunosuppressive state in organ transplantation leads to infectious complications responsible for high mortality rate. Fungal infections account for 5% of all infections in Renal Transplantation (RT) recipients. Aspergillus species are filamentous fungi frequently causing fungal infections in RT recipients. Lungs and paranasal sinuses are the usual portal of entry from where it disseminates to other organs. Here, we are reporting a case of 14-year-old boy with RT from mother's kidney, who had atypical presentation of isolated cerebral aspergillosis at 19 months post-transplant without identified portal of entry...

Delayed diagnosis in invasive aspergillosis (IA) contributes to its high mortality. Gliotoxin (GT) and bis-methyl-gliotoxin (bmGT) are secondary metabolites produced by Aspergillus during invasive, hyphal growth and may prove diagnostically useful. Because IA pathophysiology and GT's role in virulence vary depending on the underlying host immune status, we hypothesized that GT and bmGT production in vivo may differ in three mouse models of IA that mimic human disease. We defined temporal kinetics of GT and bmGT in serum, bronchoalveolar lavage fluid (BALF) and lungs of A...

The use of biomarkers for the detection of fungal infections is of interest to complement histopathological and culture methods. Since the production of antibodies in immunocompromised patients is scarce, detection of a specific antigen could be effective for early diagnosis. D-Galactofuranose (Galf) is the antigenic epitope in glycoconjugates of several pathogenic fungi. Since Galf is not biosynthesized by mammals, it is an attractive candidate for diagnosis of infection. A monoclonal antibody that recognizes Galf is commercialized for detection of aspergillosis...

The number of patients at risk of suffering invasive fungal infection (IFI) is increasing. Because of its high mortality, new rapid and accurate diagnostic tools are needed. Last advances in invasive candidiasis diagnosis comprise Peptide Nucleic Acid Fluorescent In-Situ Hybridization (PNA-FISH), direct MALDI-TOF or multiplex acid nucleic testing. While all of them rely in positive blood cultures, T2Candida uses PCR coupled with T2Magnetic resonance detection directly in whole blood, allowing detection of 1-3 UFC/mL of Candida in about four hours...

BACKGROUND: Meningitis is a life threatening central nervous system infection that is prevalent worldwide. Many studies have been conducted on bacterial meningitis, but the information is inadequate on the other types of meningitis, especially prevalent in India. Regional information regarding trends, in terms of etiology and microbiological susceptibility, are essential for timely and adequate management of meningitis. AIMS: The present study was undertaken to evaluate the changing epidemiology of meningitis by reviewing the causative agents, the available laboratory methods for making the etiological diagnosis, the risk factors and the clinical outcomes, and the management of meningitis in our patient population...

Microsporum (M.) canis is the most common fungus to cause tinea capitis in Europe, especially in the Mediterranean region and South and Central Europe. Fungal scalp infections caused by M. canis tend to be non-inflammatory. Recently, a growing number of cases of tinea capitis characterized by inflammatory infection caused by M. canis and M. gypseum have been registered. We present a case of highly inflammatory tinea capitis, also known as kerion celsi, caused by M. canis in a 6-year-old-patient. Scalp infections due to M...
