BACKGROUND: Central nervous system (CNS) infections are important contributors to morbidity and mortality and the causative agents for ~50% patients are never identified. The causative agents of some CNS infections have distinct spatial and temporal patterns. METHODOLOGY/PRINCIPAL FINDINGS: Here we present the results of a spatial epidemiological and ecological analysis of CNS infections in Lao PDR (2003-2011). The data came from hospitalizations for suspected CNS infection at Mahosot Hospital in Vientiane...

INTRODUCTION: Although sub-Saharan Africa accounts for only 21% of the global population of children and adolescents aged 5-15 years, 55% of deaths among children in this age group occur in this region. This seems to be related to infectious diseases. We hypothesized that besides infectious diseases, in our context, a chronic underlying condition increases mortality. Our goal was to describe the leading causes of mortality among this age group. PATIENTS AND METHODS: We conducted a retrospective study in a tertiary care center in Yaoundé...

PAP is an ultra-rare disease in which surfactant components, that impair gas exchange, accumulate in the alveolae. There are three types of PAP. The most frequent form, primary PAP, includes autoimmune PAP which accounts for over 90% of all PAP, defined by the presence of circulating anti-GM-CSF antibodies. Secondary PAP is mainly due to haematological disease, infections or inhaling toxic substances, while genetic PAP affects almost exclusively children. PAP is suspected if investigation for ILD reveals a crazy-paving pattern on chest CT scan, and is confirmed by a milky looking BAL that gives a positive PAS reaction indicating extracellular proteinaceous material...

Acute encephalitis is an important cause of mortality and morbidity in children. We retrospectively identified children (≤15 years of age) admitted with suspected encephalitis at the Intensive Care Unit of the Pediatric Department of Cayenne Hospital between January 2007 and December 2018. A total of 30 children with acute encephalitis were identified. The incidence rate varied from 0 to 10.40 cases/100000 children under 15 years. Proven encephalitis was diagnosed in 73% of patients. Nine cases of acute disseminated encephalomyelitis were diagnosed...

Background : Recent studies have reveled the presence of a complex fungal community (mycobiome) in the oral cavity. However, the role of oral mycobiome in dental caries and its interaction with caries-associated bacteria is not yet clear. Methods : Whole-mouth supragingival plaque samples from 30 children (6-10 years old) with no caries, early caries, or advanced caries were sequenced for internal transcribed spacer 2 (ITS-2). The mycobiome profiles were correlated with previously published bacteriome counterparts...

Cryptococcosis is a life-threatening mycosis reported mainly in human adults with low frequency in children. High mortality rates may occur in cases with late diagnosis therefore, a timely suspicion of this pathology is important. Cryptococcus gattii is the less prevalent species complex predominantly isolated from apparently normal hosts. We report a fatal case of neurocryptococcosis in a Colombian minor without known risk factors, in Barranquilla, Colombia. The patient was hospitalized for neurological assessment with a recent history of intense headache, vomiting, anorexia, loss of consciousness, drowsiness, inability to recognize family members, disorientation, aphasia and anxiety...

Cryptococcus neoformans is an opportunistic human pathogen that causes cryptococcosis, a life-threatening infection that usually manifests as meningoencephalitis in immunocompromised patients. Pigeon ( Columba livia ) droppings can spread pathogenic yeasts and mold fungi, such as C neoformans , in the environment. The objective of this study was to isolate C neoformans and other opportunistic fungi from feral pigeon droppings. One hundred twenty samples of feral pigeon droppings were suspended 1:10 in saline solution and then cultured...

BACKGROUND: Paediatric Cryptococcus gattii disease is rare, with only two previous cases recorded in the Northern Territory (NT) over the last 54 years. Immune reconstitution inflammatory syndrome (IRIS) is a recognised complication of C. gattii infection, even in the absence of an identified immunodeficiency syndrome; however, limited paediatric data exist. We present a series of three paediatric patients treated for C. gattii infection in the NT during 2016/2017. CASE DISCUSSIONS: All three cases were males aged 8-13 years at the time of presentation...

Cryptococcosis is a life-threatening mycosis primarily occurring in adult patients particularly those with immunosuppression such as HIV infection/AIDS. The number of reported cases of paediatric cryptococcosis has increased in the last decade around the world, including China. However, current information on the characteristics of cryptococcosis in children, particularly the genotypic diversity and antifungal susceptibility of the isolates, is limited. In the present study, a total of 25 paediatric isolates of Cryptococcus neoformans were genotyped using the ISHAM-MLST scheme...

BACKGROUND: Endemic waterborne zoonosis frequently occurs in both developed and less developed countries. Thus, bio-surveillance of waterborne zoonosis is a "necessity" for the implementation of effective preventive public health measures in Egyptian rural areas. The primitive individual water supplies created by the rural agriculture population, primarily from ground water, usually maximize the customers' exposure to impurity pathogens via diffused humans and animal excreta or wastages...

Patients with Mendelian Susceptibility to Mycobacterial Diseases (MSMD) exhibit variable vulnerability to infections by mycobacteria and other intramacrophagic bacteria (e.g., Salmonella and Klebsiella ) and fungi (e.g., Histoplasma, Candida, Paracoccidioides, Coccidioides , and Cryptococcus ). The hallmark of MSMD is the inherited impaired production of interferon gamma (IFN-γ) or the lack of response to it. Mutations in the interleukin (IL)-12 receptor subunit beta 1 ( IL12RB1 ) gene accounts for 38% of cases of MSMD...

Recent studies conducted in the Great Basin Desert region of the United States have shown that skin test reactivity to fungal and dust mite allergens are increased in children with asthma or allergy living in homes with evaporative coolers (EC). The objective of this study was to determine if the increased humidity previously reported in EC homes leads to varying microbial populations compared to homes with air conditioners (AC). Children with physician-diagnosed allergic rhinitis living in EC or AC environments were recruited into the study...

REVIEW
Carol Kao, David L Goldman
Cryptococcus neoformans is an encapsulated fungal pathogen that is remarkable for its tendency to cause meningoencephalitis, especially in patients with AIDS. While disease is less common in children than adults, it remains an important cause of morbidity and mortality among HIV-infected children without access to anti-retroviral therapy. This review highlights recent insights into both the biology and treatment of cryptococcosis with a special emphasis on the pediatric literature.
