Panton-Valentine Leukocidin in Necrotizing Pneumonia: A Case Report.

Panton-Valentine leukocidin (PVL)-producing is a rare but clinically significant cause of community-acquired pneumonia (CAP). This toxin leads to extensive tissue destruction and severe inflammation, often progressing to necrotizing pneumonia, septic shock, and multiorgan failure, representing a challenge in medical practice due to its rapid progression and poor prognosis. We discuss a case of a 65-year-old diabetic male who developed severe CAP leading to septic shock, respiratory failure, and multiorgan dysfunction.

Reliability and validity of a new colour-changing test food with an acid-base reaction for the clinical assessment of masticatory performance.

The aim of this study was to determine the reliability and validity of a new test food for the clinical assessment of masticatory performance. The test food had two overlapping acidic/basic halves. Ten dentate subjects chewed one unit for 10-100 cycles.

Patch size, functional isolation, visibility and matrix permeability influences neotropical primate occurrence within highly fragmented landscapes.

Forest fragmentation and habitat loss are among the major current extinction causes. Remaining fragments are mostly small, isolated and showing poor quality. Being primarily arboreal, Neotropical primates are generally sensitive to fragmentation effects.

Semi-invasive aspergillosis in an immunocompetent patient with Swyer-James-MacLeod Syndrome: a case report.

Introduction: Invasive and semi-invasive pulmonary aspergillosis usually occurs in immunocompromised patients. It has been described occasionally in patients with normal immunity and previous lung disease such as chronic obstructive pulmonary disease.Swyer-James-MacLeod Syndrome is a rare condition characterized by hyperlucency of one lung, lobe or part of a lobe due to decreased vascularity and air trapping.
