Mortality and morbidity remain high in pediatric lower respiratory tract infections (LRTIs) despite progress in research and implementation of global diagnostic and treatment strategies in the last decade. Still, 120 million annual episodes of pneumonia affect children younger than 5 years each year leading to 1.3 million fatalities with the major burden of disease carried by low- and middle-income countries (95%). The definition of pneumonia is still challenging. Traditional diagnostic measures (i.e., chest radiographs, C-reactive protein) are unable to distinguish viral and from bacterial etiology...

Neuroinfectious diseases in livestock represent a severe threat to animal health, but their prevalence is not well documented and the etiology of disease often remains unidentified. The aims of this study were to generate baseline data on the prevalence of neuroinfectious diseases in cattle in Switzerland by neuropathological survey, and to identify disease-associated pathogens. The survey was performed over a 1-year period using a representative number of brainstem samples (n=1816) from fallen cattle. In total, 4% (n=73) of the animals had significant lesions, the most frequent types of which were indicative of viral (n=27) and bacterial (n=31) etiologies...

Intravenous immunoglobulin (IVIG) is a commonly used and generally well-tolerated medication. Common side effects include flu-like symptoms such as fevers, headaches, myalgia, fatigue, and nausea. One of the more rare side effects is aseptic meningitis, with a reported incidence rate of around 0.067 percent of all IVIG infusions. In this paper, we describe a 47-year-old female patient with a history of myasthenia gravis who presented with a headache, neck pain, and neck stiffness while undergoing IVIG infusions for a myasthenia crisis...

The number of patients with immunosuppression is rising worldwide. The spectrum of diseases and pathogens in these patients differs widely from that of immunocompetent patients due to frequent opportunistic infections. Symptoms are sometimes unspecific, and imaging plays a key role in the management of these patients. The lungs are a frequent site of infection in immunosuppressed patients. Chest X‑ray is the starting point for radiological diagnostics, but shows only limited sensitivity and specificity for infections with atypical pathogens...

BACKGROUND: Leishmaniasis is a common parasitic disease seen in many parts of the world, especially in areas where current U.S. and international forces are deployed. Approximately 350 million people are thought to be at risk of cutaneous leishmaniasis (CL) with an annual incidence of 1.5 million cases. Over 90% of cutaneous infections with Leishmania occur in the Middle East, Brazil, and Peru. Outbreaks of CL may occur in military personnel deployed to endemic areas. Since the incubation period for symptomatic CL ranges from weeks to months, symptoms may not appear until well after returning to the United States...

Differential Diagnosis of bacterial and viral meningitis remains an important clinical problem. A number of methods to assist in the diagnoses of meningitis have been developed, but none of them have been found to have high specificity with 100% sensitivity.We conducted a retrospective analysis of the medical records of 148 children hospitalized in St. Joseph Children's Hospital in Poznań. In this study, we applied for the first time the original methodology of dominance-based rough set approach (DRSA) to diagnostic patterns of meningitis data and represented them by decision rules useful in discriminating between bacterial and viral meningitis...

More than 1·6 million people are estimated to die of fungal diseases each year, and about a billion people have cutaneous fungal infections. Fungal disease diagnosis requires a high level of clinical suspicion and specialised laboratory testing, in addition to culture, histopathology, and imaging expertise. Physicians with varied specialist training might see patients with fungal disease, yet it might remain unrecognised. Antifungal treatment is more complex than treatment for bacterial or most viral infections, and drug interactions are particularly problematic...

The trachea is a pivotal organ of the respiratory tract. Rather than a genuine anatomic border, it acts as a crossroad in all respiratory infectious processes. Even though not strictly limited to the trachea, infections such as laryngotracheitis and tracheobronchitis are frequently diagnosed in children, in particular during the winter season. Infectious tracheitis etiologies are diverse and the distinction between viral and bacterial origins, albeit difficult, remains relevant considering the substantial differences in terms of gravity and therapeutic management...
