OBJECTIVE To determine the efficacy of thoracoscopy in the management of children with complicated parapneumonic pleural effusion at the fibrinopurulent stage. METHODS Retrospective study of 99 children submitted to thoracoscopy for the treatment of complicated parapneumonic pleural effusion at the fibrinopurulent stage between November of 1995 and July of 2005. The mean age was 2.6 years (ra...

BACKGROUND Apoptosis plays a role in the development of pleural effusion. Caspase-cleaved cytokeratin 18, a marker for epithelial cell apoptosis, was evaluated in pleural effusion. METHODS A total of 79 patients with pleural effusion were enrolled. The underlying causes were lung cancer (n=24), parapneumonic effusion (n=15), tuberculous effusion (n=28), and transudates (n=12). The levels of M...

of large amount of pleural fluid with many polymorphonuclear leukocytes, bacteria and cellular debris. The pleural fluid becomes clottable due to leakage of plasma proteins and loss of fibrinolytic activity in pleural space resulting in the formation of thick layer of fibrin over parietal and visceral pleura. The migration of fibroblasts into pleural space leads to collagen deposition and along...

Methods: Retrospective study of 99 children submitted to thoracoscopy for the treatment of complicated parapneumonic pleural effusion at the fibrinopurulent stage between November of 1995 and July of 2005.

BACKGROUND Human adenovirus 7 (HAdV-7) was responsible for a significant number of fatalities during the 2011 community outbreak in Taiwan. The mechanisms underlying the pathogenesis of severe adenovirus infections in non-immunocompromised individuals remain unclear. Adenovirus pneumonia was associated with pleural effusion in a number of patients from the 2011 outbreak suggesting that similar ...

BACKGROUND Matrix metalloproteinases (MMPs) have been implicated in the escalation of fibrosis and remodeling which are central to the subsequent progression of a parapneumonic pleural effusion to empyema. OBJECTIVES The aim of this study was the assessment of MMP-2, MMP-8 and MMP-9 in parapneumonic pleural effusions in order to examine their value in the differentiation between uncomplicated...

BACKGROUND Community-acquired pneumonia (CAP) complicated by parapneumonic effusion/empyema is an infectious syndrome commonly encountered by physicians caring for children in Canada. OBJECTIVE To investigate the incremental benefit of novel molecular testing for the microbiological diagnosis of pediatric CAP complicated by parapneumonic effusion/empyema in Canada. METHODS A convenience sam...

This study aimed to identify the bacterial etiology of empyema thoracis or parapneumonic pleural effusions in Thai children, with a focus on pneumococcus. This hospital-based, descriptive study included children aged < or = 16 years, diagnosed with empyema thoracis or parapneumonic pleural effusion, from whom a pleural fluid (PF) sample was taken between January 2008 and November 2009. PF and b...
