Article Abstract
Background: The incidence of community-acquired empyema caused by the group (SAG) has been on the rise in the 2020s. To the best of our knowledge, while empyema caused individually by either strain has been reported, there are no reports on empyema caused by concurrent infection with these two strains. Here, we report for the first time empyema caused by concurrent infection with and (both SAG species) in a postoperative patient who had been treated for floor of the mouth carcinoma.
Case Presentation: A 61-year-old male patient who had undergone surgical treatment for floor of the mouth carcinoma 2 year earlier suddenly presented with left-sided chest pain. Chest computed tomography (CT) revealed encapsulated pleural effusion on the left side, which was diagnosed as empyema. Metagenomic next-generation sequencing(mNGS) of the pleural fluid sample indicated mixed infection caused by and . The patient's condition improved about 5 weeks after treatment with thoracic fluid drainage and cephalosporin antibiotics.
Conclusion: This case highlights the possibility of concurrent infection with two SAG strains in patients with empyema. Currently, it is unclear whether there is a definitive relationship between a surgical history of carcinoma of the floor of the mouth and empyema caused by infection with SAG strains. This case could, perhaps, serve as a reference for future related research on the topic.

Unlabelled: An increase in severe and invasive infections has been reported since the COVID-19 pandemic. However, most evidence comes from monocentric studies without nationwide representativeness. This multicenter, nationwide, retrospective study, conducted within the network of the Italian Society of Pediatric Infectious Diseases (SITIP), aimed to compare the severity of empyema at presentation in children (aged 1 month to 18 years) admitted to 19 Italian hospitals before, during, and after the pandemic.

A 58-year-old man presented with dyspnea and easy fatigability for two months and was diagnosed with empyema. Despite the initial treatment with intravenous ampicillin-sulbactam and chest tube drainage, the patient's condition did not improve. On day 12, Campylobacter coli resistant to both macrolides and fluoroquinolones was identified in the pleural fluid.

Serotype 3 pneumococcal infection can cause severe invasive disease, even in immunocompetent adults, and is potentially preventable by vaccination. Invasive pneumococcal disease caused by serotype 3 is currently the most frequent serotype found in adults in Denmark. In this report, we present a 62-year-old immunocompetent man diagnosed with a severe pleural empyema caused by serotype 3, requiring a long course of antibiotics.
