Department of Paediatrics and Child Health
Background: Pneumonia is a leading cause of death among children under 5 specifically in South Asia and sub-Saharan Africa. Hypoxaemia is a life-threatening complication among children under 5 with pneumonia. Hypoxaemia increases risk of mortality by 4.3 times in children with pneumonia than those without hypoxaemia. Prevalence of hypoxaemia varies with geography, altitude and severity (9%-39% Asia, 3%-10% African countries). In this protocol paper, we describe research methods for assessing impact of Lady Health Workers (LHWs) identifying hypoxaemia in children with signs of pneumonia during household visits on acceptance of hospital referral in district Jamshoro, Sindh.

Invasive Pulmonary Infection By Syncephalastrum Species: Two Case Reports And Review Of Literature, Memoona Irshad, Nosheen Nasir, Urooj Haider Hashmi, Joveria Farooqi, Syed Faisal Mahmood
Section of Internal Medicine
Background: Syncephalastrum species belong to the class Zygomycetes and order Mucorale. These are found in the environment and tropical soil, usually presenting as colonizers and rarely cause human infection. Syncephalastrum racemosum is a species of the genus Syncephalastrum and is the most commonly identified pathogen. Most cases are reported in immunocompromised individuals, such as patients on long term steroids, poorly controlled diabetes, or patients with malignancy.
Case presentation: We are describing two cases of rare fungal infection by Syncephalastrum species causing invasive pulmonary manifestation. Both patients had compromised immune status and presented with worsening dyspnea to the emergency room. Both …
Oral Fungal Microbiota: To Thrush And Beyond, Dennis J. Baumgardner
Oral Fungal Microbiota: To Thrush And Beyond, Dennis J. Baumgardner
Journal of Patient-Centered Research and Reviews
The oral microbiota is complex, multikingdom, interactive, and involves extensive biofilm formation. While dominated by bacteria, Candida is a frequent member of this microbiota; however, several other potentially pathogenic fungi (among around 100 identified species) appear to reside in some individuals, including Cryptococcus, Aspergillus, and Fusarium. Oral candidiasis may manifest as a variety of disease entities in normal hosts and in the immunocompromised. These include pseudomembranous candidiasis (thrush), hyperplastic or atrophic (denture) candidiasis, linear gingival erythema, median rhomboid glossitis, and angular cheilitis. The purpose of this review is to describe the oral fungal microbiota (ie, oral mycobiota), …
The Essential Role Of Carbon Metabolism In The Virulence Of Cryptococcus Neoformans, Mara Weigner
The Essential Role Of Carbon Metabolism In The Virulence Of Cryptococcus Neoformans, Mara Weigner
Senior Honors Theses
Cryptococcus neoformans infections are a major cause of meningoencephalitis in immunosuppressed patients worldwide. Inhaled as spores or desiccated yeast cells, C. neoformans can undergo metabolic changes in response to the new host environment that allow it to cross the blood brain barrier and cause deadly central nervous system (CNS) infections. Nutrient acquisition, and specifically carbon metabolism, is critical for survival and proliferation within the host. Notably, efficient carbon metabolism is necessary to produce the polysaccharide capsule, which is arguably C. neoformans’ most important and well-studied virulence factor. As such, a better understanding of carbon acquisition and regulation is essential for …

Amphotercin Washout Of Fungal Peritonitis In Liver Transplant Recipient: A Novel Approach, Ann Thompson Do, Mara Piltin Do, Alyssa Imperatore Do, Ely Sebastian Md, Sandra Paluzzi Md
Rowan-Virtua Research Day
Invasive fungal infection has a significant prevalence among organ transplant patients and is associated with high rates of morbidity and mortality. Fungal infection is difficult to identify early and subsequently difficult to effectively treat. In this case presentation we have a 45 y/o orthotopic liver transplant recipient who was profoundly sick from fungal peritonitis and due to the appearance of her abdomen and intestines, with the help of infectious disease, decided to proceed with direct amphotercin washout of the abdomen in the operating room. The patient had complete resolution of her fungal peritonitis and is doing well.

Mucorales fungal infection is a fungal disease with potentially fatal outcomes. The most frequent involvement in humans comes from the orders known as Mucorales and Entomophthorales. Mucorales is more acute and has a predilection for immunocompromised patients. Mucorales are associated with an affinity for vessels, which leads to invasion and infarction of tissue. Mucormycosis is a devastating complication that can be a life threatening fungal invasion in many patients in an immunocompromised state.

Central nervous system (CNS) involvement occurs in 5 to 10% of individuals with disseminated histoplasmosis. Most experience has been derived from small single center case series, or case report literature reviews. Therefore, a larger study of central nervous system (CNS) histoplasmosis is needed in order to guide the approach to diagnosis, and treatment.
A convenience sample of 77 patients with histoplasmosis infection of the CNS was evaluated. Data was collected that focused on recognition of infection, diagnostic techniques, and outcomes of treatment.
Twenty nine percent of patients were not immunosuppressed. Histoplasma antigen, or anti-Histoplasma antibodies were detected in the …
Freshwater Fungal Infections, Dennis J. Baumgardner
Freshwater Fungal Infections, Dennis J. Baumgardner
Dennis J. Baumgardner, MD
Fungal infections as a result of freshwater exposure or trauma are fortunately rare. Etiologic agents are varied, but commonly include filamentous fungi and Candida. This narrative review describes various sources of potential freshwater fungal exposure and the diseases that may result, including fungal keratitis, acute otitis externa and tinea pedis, as well as rare deep soft tissue or bone infections and pulmonary or central nervous system infections following traumatic freshwater exposure during natural disasters or near-drowning episodes. Fungal etiology should be suspected in appropriate scenarios when bacterial cultures or molecular tests are normal or when the infection worsens or fails …

Dynamic Host-Pathogen Interactions Result In Fungal Epitope Unmasking, Alex Hopke
Dynamic Host-Pathogen Interactions Result In Fungal Epitope Unmasking, Alex Hopke
Electronic Theses and Dissertations
Molecular camouflage is used by a diverse set of pathogens to disguise their identity and avoid recognition by protective host receptors. The opportunistic fungal pathogen Candida albicans is a good example, as it masks the inflammatory component β-glucan in its cell wall to evade detection by the immune receptor Dectin-1. Interestingly, it has been seen that β-glucan becomes unmasked during infection in vivo, though the underlying mechanisms remained unclear. Exposure levels of this epitope may be important, as Dectin-1 mediates protection from some strains of C. albicans and alterations in the organization and composition of the Candida cell wall …

Geodemographic Features Of Human Blastomycosis In Eastern Wisconsin, Megan E. Huber, Dennis J. Baumgardner, Jessica J. F. Kram, Melissa A. Lemke
Dennis J. Baumgardner, MD
Purpose
Blastomycosis is an endemic fungal infection. In rural northern Wisconsin, blastomycosis cases are associated with certain environmental features including close proximity to waterways. Other studies have associated blastomycosis with particular soil chemicals. However, blastomycosis also occurs in urban and suburban regions. We explored the geodemographic associations of blastomycosis cases in the more urban/suburban landscape of eastern Wisconsin.
Methods
We conducted a retrospective study of 193 laboratory-identified blastomycosis cases in a single eastern Wisconsin health system, 2007–2015. Controls were 250 randomly selected cases of community-diagnosed pneumonia from a similar time period. Geographic features of home addresses were explored using Google …
