Pediatric community acquired pneumonia (CAP) is frequently encountered by medical providers and is one of the most common reasons for hospital admission. CAP is known to cause significant morbidity and mortality, causing greater than 2 million deaths annually worldwide in children younger than five years old. The Infectious Disease Society of America (IDSA) released guidelines in 2011 with recommendations regarding appropriate diagnosis and management of community acquired pneumonia for children greater than 3 months age, with the goal of assisting providers in clinical decision making...

The use of fever syndromic surveillance in sub-Saharan Africa is an effective approach to determine the prevalence of both malarial and nonmalarial infectious agents. We collected both blood and naso/oro-pharyngeal (NP/OP) swabs from consecutive consenting patients ≥ 1 year of age, with an axillary temperature ≥ 37.5°C, and symptom onset of ≤ 5 days. Specimens were analyzed using both acute febrile illness (AFI) and respiratory TaqMan array cards (TAC) for multiagent detection of 56 different bloodstream and respiratory agents...

Vertigo is a multisensory syndrome that otolaryngologists are confronted with every day. With regard to the complex functions of the sense of orientation, vertigo is considered today as a disorder of the sense of direction, a disturbed spatial perception of the body. Beside the frequent classical syndromes for which vertigo is the leading symptom (e.g. positional vertigo, vestibular neuritis, Menière's disease), vertigo may occur as main or accompanying symptom of a multitude of ENT-related diseases involving the inner ear...

Bacterial and viral lower respiratory tract infections (LRTIs) are often clinically indistinguishable, leading to antibiotic overuse. We compared the diagnostic accuracy of a new assay that combines 3 host-biomarkers (TRAIL, IP-10, CRP) with parameters in routine use to distinguish bacterial from viral LRTIs. Study cohort included 184 potentially eligible pediatric and adult patients. Reference standard diagnosis was based on adjudication by an expert panel following comprehensive clinical and laboratory investigation (including respiratory PCRs)...

Munashe Chigerwe, Meera C Heller
Infectious enteritis in adult ruminants is often a result of 1 or more viral, bacterial, or parasitic pathogens. Diagnosis of etiologic agents causing enteritis is important when considering herd implications and zoonotic potential of some etiologies. Differential diagnoses for enteritis in adult ruminants is not simple based on clinical signs alone. Diagnostic samples include feces, blood, and antemortem and postmortem tissues. Treatment of infectious enteritis is aimed at correcting dehydration and electrolyte imbalances secondary to diarrhea...

FilmArray GI Panel (BioFire Diagnostics, Salt Lake City, UT) is a multiplex, on-demand, sample-to-answer, real-time PCR assay for the syndromic diagnosis of infectious gastroenteritis that has become widely adopted and, in some instances, replaced conventional stool culture and parasite exams. Conventional testing has historically been restricted among hospitalized patients due to low diagnostic yield, but it is not known whether use of the FilmArray GI Panel should be circumscribed. Cary-Blair stool samples submitted for FilmArray GI Panel in adult patients admitted to an academic hospital from August 2015 to January 2017 were included in this study...

Available methods for the diagnosis of coccidioidomycosis have significant shortcomings relative to accuracy and timeliness. We retrospectively and prospectively evaluated the diagnostic performance and reproducibility of a new cartridge-based real-time PCR assay for Coccidioides spp. directly in lower respiratory secretions and compared them to today's gold standard fungal culture. The GeneSTAT® Coccidioides Assay uses a 106-bp target sequence repeated multiple times (∼60X) per genome, thus, lowering the limit of detection (LOD) for extracted DNA to 10 genome equivalents/ml...

Introduction: Acute Encephalitis Syndrome has heralded the emergence of multiple virulent pathogens, which may result in severe morbidity and mortality. In India, encephalitis is not notified and there has been a dearth of analysis for trends in encephalitis death rates and causation. A downward trend has been observed in encephalitis deaths, due to 'known' causes, which can be largely explained by improvement in diagnostic, treatment, and prevention methods. There is still a very high proportion of encephalitis deaths in developing countries, where the aetiological diagnosis of the pathogen is not established and thus, lies the importance of monitoring encephalitis morbidity and mortality with a view to improve pathogen diagnosis and identify emerging infectious diseases...

Molecular diagnostics of drug resistant pathogens requires analysis of point mutations in bacterial or viral genomes, which is usually performed by trained professionals and/or by a sophisticated computer algorithm. Here, we developed a DNA-based logic system that autonomously analyzes mutations in the genome of Mycobacterium tuberculosis complex (MTC) bacterial species and communicates the output to a human user as alphanumeric characters read by the naked eye. The five-gate system displays "O" ("no infection") for the absence of MTC infection; and "P" or "F" for passing or failing a drug susceptibility test, respectively...

Pericardial effusion of various sizes is a quite common clinical finding, while its progression to effusive-constrictive pericarditis occurs in about 1.4-14% of cases. Although available evidence on prevalence and prognosis of this rare pericardial syndrome is poor, apparently a considerable proportion of patients conservatively managed has a spontaneous resolution after several weeks. A 61-year-old female presented to our emergency department reporting fatigue, effort dyspnea and abdominal swelling. The echocardiography showed large pericardial effusion with initial hemodynamic impact, so she underwent a pericardiocentesis with drainage of 800-850cm(3) of exudative fluid, on which diagnostic investigations were undertaken: possible viral and bacterial infections, medical conditions, iatrogenic causes, neoplastic and connective tissue diseases were all excluded...

Patients with cystic fibrosis (CF) suffer from chronic lung infections, caused by bacterial, viral or fungal pathogens, which determine morbidity and mortality. The contribution of individual pathogens to chronic disease and acute lung exacerbations is often difficult to determine due to the complex composition of the lung microbiome in CF. In particular, the relevance of fungal pathogens in CF airways remains poorly understood due to limitations of current diagnostics to identify the presence of fungal pathogens and to resolve the individual host-pathogen interaction status...

Influenza virus infections are extremely important for human health due to the occurence of seasonal epidemics and pandemics worldwide. Influenza is associated with high morbidity and may result in serious complications such as life threatening viral or bacterial pneumonia. Especially, young children, older adults, patients with chronic diseases such as heart, lung, kidney, and diabetes and immunosuppressed people are at higher risk for complications and death from influenza virus infections. The aim of this study was to determine the incidence of influenza type A and B virus infections and influenza A virus subtypes in hospitalized patients with respiratory tract infections by real-time reverse transcriptase-polymerase chain reaction (RT-PCR, Sacace, Italy), conventional RT-PCR and direct immunofluorescence antibody (DFA, Argene SA, France) tests...

Due to overlap of clinical findings and low sensitivity of bacterial diagnostic tests, differentiation between bacterial and viral respiratory tract infections remains challenging, ultimately leading to antibiotic overuse in this population of patients. Addition of procalcitonin, a blood biomarker expressed by epithelial cells in response to bacterial infections, to the clinical assessment leads to a reduction in inappropriate antibiotic initiation. Procalcitonin also provides prognostic information about the resolution of illness, and significant decreases over time are a strong signal for the discontinuation of antibiotics...

BACKGROUND: Translational science supports successful transition of early biomedical research into human applications. In 2009 a translatability score to assess risk and identify strengths and weaknesses of a given project has been designed and successfully tested in case studies. The score elements, in particular the contributing weight factors, are heterogeneous for different disease areas; therefore, the score was individualized for six areas (cardiovascular, oncology, psychiatric, anti-viral, anti-bacterial/fungal and monogenetic diseases)...
