Blood Eosinophils as a Switch for Inhaled Steroids in Indian COPD Clinics COPD clinics in India still hand out inhaled corticosteroids by habit. Many patients leave with a triple inhaler after one noisy chest. Blood eosinophils offer a cheaper way to decide who actually needs the steroid. The test is a cell count, not a […]

Most of those drugs still require an injection every two to eight weeks. Missed visits then become missed protection. Depemokimab is built to stretch that interval to twice a year. The drug is an […]

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. […]
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 […]

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 […]
