Abstract:
A 77-year-old man underwent radiotherapy for the squamous cell carcinoma of the right lung. Two months after the 60Gy/30fr irradiation was completed, he complained of dyspnea and his chest X-ray showed ground glass opacities and reticular shadows in both lung fields. Severe radiation pneumonitis was diagnosed. Two grams of methylprednisolone did not improve his symptoms and on the next day his hypoxemia worsened. We then tried plasma exchange because of his critical status. His respiratory status improved rapidly after plasma exchange and his chest X-ray showed remarkable improvement 10 days later. We think this case suggests the effectiveness of plasma exchange for severe radiation pneumonitis.

Pleural Effusion II: Symptoms and Management
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.

Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:
