BACKGROUND: Adenovirus is a common pathogen of acute upper respiratory infection in children and is generally self-limiting. Severe adenovirus infections have been reported in immunocompromised hosts especially bone marrow transplantation recipients due to hematologic malignancy. Severe adenovirus pneumonia in immunocompetent hosts has rarely been reported and optimal treatment has not been established. We report a case of community-acquired severe adenovirus pneumonia which was successfully treated with early administration of oral ribavirin...

Tuberculosis is a public health problem worldwide, including in the United States-particularly among immunocompromised patients and other high-risk groups. Tuberculosis manifests in active and latent forms. Active disease can occur as primary tuberculosis, developing shortly after infection, or postprimary tuberculosis, developing after a long period of latent infection. Primary tuberculosis occurs most commonly in children and immunocompromised patients, who present with lymphadenopathy, pulmonary consolidation, and pleural effusion...

BACKGROUND A logical consequence of the introduction of robotics and high capacity analysers has seen a consolidation to larger units. This requires new structures and quality systems to ensure that laboratories deliver consistent and comparable results. METHODS A spreadsheet program was designed to accommodate results from up to 12 different Instruments/laboratories and present IQC data i.e. Levey-Jennings and Youden plots and comprehensive numerical tables of the performance of each item. Input of data was made possible by a "data loader" by which IQC data from the individual instruments could be transferred to the spreadsheet program on line...

INTRODUCTION: Stem cell transplantation is today's procedure of choice for management of various hematopoietic malignant and severe immunogenic disorders. High Resolution Computed Tomography (HRCT) is a common technique for the diagnosis of pulmonary complications in stem cell transplant recipients. There are a large number of complications which can complicate the post-transplant period. AIM: To study the role of HRCT chest in stem cell transplant patients developing pulmonary complications, detect any evidence of infection, detect clinical signs of lung infections, Graft versus Host Disease (GvHD) or other regimen related toxicities outlined earlier, detect any evidence of GvHD and correlate these clinical signs with radiological changes in the lungs...

Adenovirus (AdV) can cause severe pneumonia in non-immunocompromised host, but limited data exist on the distinctive characteristics of AdV pneumonia in non-immunocompromised patients. We evaluated distinctive clinico-laboratory and radiological characteristics and outcomes of AdV pneumonia (n = 179), compared with non-AdV pneumonia (n = 188) in Korean military personnel between 2012 and 2016. AdV pneumonia patients had a higher rate of consolidation with ground-glass opacity (101/152) in lobar distribution (89/152) on computed tomography (CT) (P < 0...

Cryptococcus neoformans is an environmentally ubiquitous fungal pathogen that primarily causes disease in people with compromised immune systems, particularly those with advanced AIDS. There are estimated to be almost one million cases per year of cryptococcal meningitis in patients with human immunodeficiency virus, leading to over 600,000 annual deaths, with a particular burden in sub-Saharan Africa. Amphotericin B (AMB) and fluconazole (FLC) are key components of cryptococcal meningitis treatment: AMB is used for induction, FLC for consolidation, maintenance, and in occasional individuals, prophylaxis...

Screening and pre-emptive isolation of at-risk patients is an important aspect of the Danish approach to the prevention of MRSA infection, but screening with conventional culture can take up to th days for results to become available with attendant costs and disadvantages of prolonged isolation. We sought to evaluate the accuracy, time to availability of results, and potential economic benefits of two next generation MRSA screening assays, Xpert® MRSA Gen 3 and BD MAX™ MRSA XT, in a setting of a consolidated laboratory serving a number of hospitals with a low prevalence of MRSA, and using enrichment culture as a reference method...

Eighty-six percent of those engaged in HIV medical care in Massachusetts achieved viral suppression, making Massachusetts's long-term goal of eliminating new infections of HIV a real possibility. In order to achieve this goal, Massachusetts is working to engage all individuals living with HIV/AIDS in HIV medical care, keep them retained in care, and render their viral load non-detectable. Currently, in Massachusetts, the data elements necessary to monitor the HIV care continuum are documented in siloed health information systems that do not communicate with each other...

Cryptococcosis has been one of the most common opportunistic infections and causes of mortality among HIV-infected patients, especially in resource-limited countries. Cryptococcal meningitis is the most common form of cryptococcosis. Laboratory diagnosis of cryptococcosis includes direct microscopic examination, isolation of Cryptococcus from a clinical specimen, and detection of cryptococcal antigen. Without appropriate treatment, cryptococcosis is fatal. Early diagnosis and treatment is the key to treatment success...

INTRODUCTION: Tuberculosis (TB) is one of the most important public health problems worldwide. Detecting patients with active pulmonary TB (PT) is an important component of TB control programs. However, at times in patients even with a compatible clinical picture, sputum smears do not reveal acid-fast bacilli (AFB) and smear-negative PT remains a common problem. This study compares the results of induced sputum (IS) and bronchial washings (BWs) in detecting sputum negative PT. MATERIALS AND METHODS: A prospective study conducted from June 2014 to June 2015, comprising 120 patients fulfilling study criteria...

The putative biological activity of 24,25-(OH)2D remains unclear. Previous studies showed an increase in the circulating levels of this metabolite following fracture in chicks. Our laboratory has generated a mouse model deficient for the Cyp24a1 gene for studying the role of 24,25-(OH)2D. We set out to study the role of CYP24A1 and 24,25-(OH)2D in intramembranous bone formation during distraction osteogenesis in wild-type and Cyp24a1-deficient mice. Distraction osteogenesis was applied to mouse tibiae using a miniature external fixator apparatus...

BACKGROUND: Researchers have used prostate-specific antigen (PSA) values collected by central cancer registries to evaluate tumors for potential aggressive clinical disease. An independent study collecting PSA values suggested a high error rate (18%) related to implied decimal points. To evaluate the error rate in the Surveillance, Epidemiology, and End Results (SEER) program, a comprehensive review of PSA values recorded across all SEER registries was performed. METHODS: Consolidated PSA values for eligible prostate cancer cases in SEER registries were reviewed and compared with text documentation from abstracted records...

Fear extinction is the laboratory basis of exposure therapy for anxiety disorders. Recent findings have revealed that estradiol is necessary to the consolidation of extinction memories in females. These findings are based on studies conducted using virgin rats and young women whose reproductive history is unknown. We hypothesized that motherhood, which results in extensive endocrinological, neurobiological and behavioral changes, may lead to alterations in fear extinction in females. We used a cross-species translational approach to investigate the impact of reproductive experience on fear extinction and fear relapse in female rats (n=116) and women (n=64)...

Scaling up access to HIV viral load testing for individuals undergoing antiretroviral therapy in low-resource settings is a global health priority, as emphasised by research showing the benefits of suppressed viral load for the individual and the whole population. Historically, large-scale diagnostic test implementation has been slow and incomplete because of service delivery and other challenges. Building on lessons from the past, in this Personal View we propose a new framework to accelerate viral load scale-up and ensure equitable access to this essential test...
