Despite the strong association between Cryptococcus neoformans infection and the Human immunodeficiency virus (HIV) status of patients globally, most cryptococcosis cases in Far East Asia occur in non-HIV individuals. Molecular epidemiological studies, using multilocus sequence typing (MLST), have shown that more than 95% of cryptococcal strains belong to a specific subtype of VNI. However, this association has never been specifically examined in other parts of Asia. Therefore, in this study, we investigated the VNIc/ST5 genotype distribution among cryptococcosis patients in Thailand...

Oral and maxillofacial fungal infections can appear in high-risk patients, including those immunocompromised. This article explores common oral manifestations of fungal infections in the oral cavity as primary lesions or as a result of disseminated disease. By far the most common oral fungal infection experienced in dentistry is oral candidiasis, which is reviewed in depth from simple oral infections to invasive candidiasis. The review aids the dental practitioner in understanding the full scope of Candida infections and other fungal infections...

BACKGROUND: Current understanding of human immunodeficiency virus (HIV)-associated pulmonary cryptococcosis (PC) is largely based on studies performed about 2 decades ago which reported that the most common findings on chest radiograph were diffuse interstitial infiltrates. Few studies are available regarding the computed tomography (CT) findings. The aim of this study was to characterize chest CT features of HIV-associated PC. METHODS: HIV patients with cryptococccal infection and pulmonary abnormalities on Chest CT between September 2010 and May 2016 in the Second Affiliated Hospital of the Southeast University were retrospectively analyzed...

Cryptococcosis is a fungal infection caused by Cryptococcus neoformans that tends to affect immunocompromised individuals. The fungi are mostly acquired by inhalation, which leads to an initial pulmonary infection. Later, other organs - such as the central nervous system and the skin - can be affected by hematogenous spread. In addition, cutaneous contamination can occur by primary inoculation after injuries (primary cutaneous cryptococcosis), whose diagnosis is defined based on the absence of systemic involvement...

BACKGROUND: Deep cutaneous fungal infections, including subcutaneous mycoses and systemic fungal infection with cutaneous involvement, cause significant morbidity and mortality in light of increasing immunocompromised patients and global warming. Although a few studies reviewed deep fungal infections in temperate regions, a relevant study in tropical regions is lacking. We evaluated features of deep cutaneous fungal infections in southern Taiwan among the tropical regions. METHODS: We retrospectively reviewed all histopathological specimens with deep cutaneous fungal infections in a single referral center from 2001 to 2014 and successfully identified 23 cases...

Pulmonary cryptococcosis is an opportunity infection commonly occurred in the immunocompromised patients. However pulmonary cryptococcosis in the immunocompetent was reported up to 35% and these cases tend to show confined and localized radiologic findings than in immunocompromised patients. To our knowledge, extensive air-space consolidations have not frequently occurred in the immunocompetent patient. Therefore, in this case, we report a rare case of a 73-year-old woman who was diagnosed with pulmonary cryptococcosis, manifesting as diffuse air-space consolidations even though normal immune status...

Cryptococcus spp. other than Cryptococcus neoformans or Cryptococcus gattii were previously considered saprophytes and thought to be non-pathogenic to humans. However, opportunistic infections associated with non-neoformans and non-gattii species, such as Cryptococcus laurentii and Cryptococcus albidus, have increased over the past four decades. We experienced a case of cryptococcosis caused by non-neoformans and non-gattii spp. in a 47-year-old female with refractory acute myeloid leukemia after allogeneic hematopoietic stem cell transplantation...

Magnetic resonance (MR) scanning has become an important diagnostic and management tool in cryptococcal meningitis (CM). However, there are only isolated case reports documenting neuroradiological findings in human immunodeficiency virus (HIV)-negative patients with CM and none has clearly addressed the relationship between cerebral lesions on magnetic resonance imaging (MRI) and prognosis. The MR brain images available from 114 HIV-negative patients with CM were retrospectively analysed. Patients were divided into Group I with one or more CM-related lesions and Group II without CM-related lesions...

BACKGROUND: Cryptococcus neoformans is an encapsulated yeast causing mainly opportunistic infections. The virulence factors involved in cryptococcosis pathogenesis include the presence and the size of the polysaccharide capsule, the production of melanin by phenoloxidase, the growth at 37°C and the enzyme secretion like proteinase, phospholipase and urease. Many other enzymes are secreted by C. neoformans but their role in the fungus virulence is not yet known. AIMS: In order to investigate this topic, we compared the phospholipase production between strains from patients and from bird droppings, and we examined its relationship to phenoloxidase production...

There is a lack of knowledge on the epidemiology of fungal infections worldwide because there are no reporting obligations. The aim of this study was to estimate the burden of fungal disease in Portugal as part of a global fungal burden project. Most published epidemiology papers reporting fungal infection rates from Portugal were identified. Where no data existed, specific populations at risk and fungal infection frequencies in those populations were used in order to estimate national incidence or prevalence, depending on the condition...

There are currently no nationwide epidemiological data on fungal infections in Canada. We estimated the burden of serious fungal diseases using literature review and modeling, as per a methodology previously described by the LIFE program ( http://www.LIFE-worldwide.org ). Among the population of Canada (35.5 million in 2014), it was estimated that approximately 1.8% are affected by a serious fungal infection. Recurrent vulvovaginal candidiasis, severe asthma with fungal sensitization, and allergic bronchopulmonary aspergillosis are the most frequent infections, with population prevalences of 498,688 (1403/100,000), 73,344 (206/100,000), and 61,854 (174/100,000) cases, respectively...

A 73-year-old man with type 2 diabetes mellitus and end-stage renal disease was diagnosed with acute myocardial infarction. He required continuous dialysis after percutaneous coronary intervention. Subsequently, multiple nodules were discovered in both lungs for the first time, and Cryptococcus neoformans was isolated from the patient's sputum, blood, bilateral pleural fluid, and cerebrospinal fluid cultures, resulting in a diagnosis of disseminated cryptococcosis. This case represents an invaluable example of disseminated cryptococcosis with rapidly growing lung nodules in a dialysis patient, and illustrates that dialysis causes innate immune disorder and the reactivation of cryptococcosis...

BACKGROUND: Cryptococcosis is an uncommon fungal infection in humans and mammals. Occasionally, cryptococcosis manifests as cutaneous lesions, either as an extension of nasal disease or as stand alone lesions unassociated with the nose. Histologically, these lesions are typically characterized by abundant organisms with mild granulomatous dermatitis. Herein, four feline cases of atypical cutaneous cryptococcal infections are described. METHODS: Skin punch biopsies from four client owned cats were submitted for histological evaluation between 2006 and 2015...

Cryptococcosis is an invasive fungal infection that is common in immunocompromised patients. A 22-year-old woman with Ewing sarcoma in the right proximal humerus was treated by resection and chemotherapy. Computed tomography detected a small nodule in her right upper pulmonary lobe after completion of her chemotherapy. With the presumptive diagnosis of pulmonary metastasis, she underwent resection. Evaluation of the resected specimen revealed pulmonary cryptococcosis, and the patient was treated with oral fluconazole for 18 weeks...
