Influenza and Viral Pneumonias
Influenza and Viral Pneumonias Influenza is a seasonal respiratory virus. It attacks the airway lining. Most cases stay in the upper tract. Some spread into the lung and become pneumonia. Other viruses can do the same. Respiratory syncytial virus, SARS-CoV-2, adenovirus, and parainfluenza are common examples. Viral pneumonia means infection of the lung tissue by […]
Chest Radiograph Patterns in Common Pulmonary Diseases The chest radiograph remains the first imaging test in lung disease. It does not replace CT or microbiology. Still, pattern recognition guides the next step. Clinicians should read the film with the history in mind. Consolidation appears as a dense, homogeneous opacity. Air bronchograms often run through it. […]

Barrett’s Ablation Techniques
Barrett’s Ablation Techniques Barrett’s esophagus replaces the normal squamous lining of the distal esophagus with columnar epithelium. Intestinal metaplasia in that lining raises the risk of dysplasia and adenocarcinoma. Ablation aims to destroy the abnormal mucosa so squamous epithelium can grow back. Doctors first confirm the diagnosis with endoscopy and biopsy. Ablation is usually reserved […]
Cystic Fibrosis Lung Disease and Modulator Therapy Cystic fibrosis is a genetic disease. Mutations in the CFTR gene impair a chloride channel. Salt and water movement across airway surfaces then fails. Mucus becomes thick. Infection and inflammation follow. The lung pays the highest price. Airway surface liquid normally stays thin enough for cilia to clear […]
How the E1-A226V Mutation Helped Chikungunya Spread Through Aedes albopictus Chikungunya virus usually rides Aedes aegypti. A single amino-acid change later improved its fit for another mosquito. That change is E1-A226V. It replaces alanine with valine at position 226 of the E1 envelope protein. E1 helps the virus fuse with a host cell. Fusion occurs […]

Sarcoidosis of the Lung
Sarcoidosis of the Lung Sarcoidosis is a multisystem disease of unknown cause. Non-caseating granulomas form in affected organs. The lung and the intrathoracic lymph nodes are involved in most patients. Many cases come to light on a chest radiograph done for another reason. Others present with cough, breathlessness, or fatigue. The typical chest pattern is […]
