Abstract:
Immune checkpoint inhibitors (ICIs) have brought about major advances in the treatment of cancer over the past 15 years. With a growing armoury of these immunotherapies available and an ever-expanding list of indications for their use, ICIs have become a standard of care in the treatment of cancers including nonsmall cell lung cancer, melanoma and renal cell carcinoma. ICIs are generally well tolerated by patients; however, they bring with them a novel class of toxicities, termed immune-related adverse events. ICI-associated pneumonitis (CIP) is among the most clinically important immune-related adverse events due to both its high incidence and associated morbidity. CIP is associated with a nonspecific clinical presentation, a heterogeneous imaging appearance and an unpredictable clinical course. In this review, we discuss the biology of immune checkpoint inhibition and the epidemiology, clinical manifestations and management of CIP. Additionally, we discuss less well described manifestations of ICI-related pulmonary toxicity: immune-mediated pleural effusion and sarcoid-like reactions.

Chronic Obstructive Pulmonary Disease-III: Symptoms and Complications.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
Primary Symptoms of COPD:
Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

COPD: Pathogenesis and Clinical Features
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...
