Pneumonitis associated with fluoropolymer waterproofing agents, an entity with few reported cases, can result from occupational exposure. This condition has a rapid onset after exposure, usually resolves with supportive treatment but there could be chronic sequelae. The authors report the case of a 48-year-old male patient admitted to hospital with acute onset of dyspnea and chest pain after using an aerosolized fluoropolymer-containing waterproofing product. He presented tachypnea, leukocytosis, elevated C reactive protein, elevated serum lactate dehydrogenase and hypoxemic respiratory failure. Chest computed tomography revealed bilateral ground-glass opacities with peribronchovascular distribution. The patient was treated with oxygen and corticosteroid therapy, with clinical improvement. This chemical pneumonitis represents a diagnostic challenge since it implies a history of exposure to toxic agents and the pathophysiological mechanisms and safe exposure limits are still unknown.

Background: The aim of this study was to investigate the clinical characteristics of severe pneumonia caused by human bocavirus (HBoV) infection to explore the associated risk factors.

Methods: We conducted a retrospective review of data from children hospitalized with HBoV pneumonia. Based on the severity of pneumonia, patients were categorized into severe pneumonia and non-severe pneumonia groups.

Introduction: Despite many studies on the prevalence of vertebral fractures (VFs), the VF prevalence at death in the Japanese population remains unclear.

Materials And Methods: We evaluated the VF prevalence at death in a Japanese cohort using autopsy imaging computed tomography (AiCT). We enrolled 365 cadavers (188 men, 177 women, mean age of 84.

SARS-CoV-2 is the viral pathogen responsible for COVID-19. Although morbidity and mortality frequently occur as a result of lung disease, the gastrointestinal (GI) tract is recognized as a primary location for SARS-CoV-2. Connections and interactions between the microbiome of the gut and respiratory system have been linked with viral infections via what has been referred to as the 'gut-lung axis' with potential aerodigestive communication in health and disease.

Coronavirus disease 2019 (COVID-19) presents a wide spectrum of symptoms, the causes of which remain poorly understood. This study explored the associations between autoantibodies (AABs), particularly those targeting G protein-coupled receptors (GPCRs) and renin‒angiotensin system (RAS) molecules, and the clinical manifestations of COVID-19. Using a cross-sectional analysis of 244 individuals, we applied multivariate analysis of variance, principal component analysis, and multinomial regression to examine the relationships between AAB levels and key symptoms.
