Chronic bronchitis is a chronic, progressive disease that is difficult to treat. Despite much effort, patients remain highly symptomatic. Currently, a number of innovative bronchoscopic treatments for this disease are under investigation. Liquid nitrogen metered cryospray, bronchial rheoplasty and balloon desobstruction all aim to destroy the hyperplastic goblet cells and excess submucous glands using different strategies. These therapies are in an early phase of clinical research and larger randomised controlled trials are needed to confirm the pilot data available and to evaluate the treatment durability. The fourth technique, targeted lung denervation (TLD), aims to decrease the release of acetylcholine, which regulates smooth muscle tone and mucus production by ablating the parasympathetic nerves running alongside the main bronchi. Evaluation of this treatment is at a more advanced stage and promising effects on exacerbation frequency have been shown. However, confirmation of the benefit in improvement in chronic bronchitis symptoms is still needed.

Objectives: Most studies on long-term sequelae of SARS-CoV-2-infection in children were conducted pre-Omicron and pre-dated vaccination rollout. We examined long-term risk of new-incident multi-systemic sequelae after SARS-CoV-2 Delta/Omicron infection in a multi-ethnic Asian pediatric population.
Methods: Retrospective cohort study of Singaporean children aged 1- 17 years infected during Delta/Omicron BA.

Cough is one of the most common reasons patients seek medical care in the outpatient setting. Chronic cough (CC) in adults is defined as a cough lasting more than 8 weeks, with a global prevalence of approximately 10%. CC significantly impairs quality of life, affecting physical, social, and psychological well-being.

Chronic obstructive pulmonary disease (COPD) is a type of lung disease marked by permanent damage to tissues in the lungs. Over time, chronic obstructive pulmonary disease (COPD) can make breathing difficult due to permanent lung damage. COPD encompasses two main conditions chronic bronchitis, where inflammation and scarring narrow the large airways, and emphysema, where the tiny air sacs in the lungs are damaged.

A saber-sheath trachea is a type of tracheal deformity characterized by coronal narrowing and sagittal widening of the intrathoracic trachea. In this case report, we describe a 76-year-old man with a history of chronic obstructive pulmonary disease (COPD) and repeated episodes of type 2 respiratory failure that responded poorly to inhaled long-acting β2 agonists, long-acting muscarinic antagonists, and corticosteroids. The patient was admitted to our hospital due to a COPD exacerbation.

Introduction: Ethylene oxide (EtO) is a reactive gas commonly used in the production of various chemical compounds. Research has linked EtO exposure to respiratory conditions, including chronic obstructive pulmonary disease (COPD) and asthma. However, its potential effects on chronic bronchitis (CB) remain unclear, highlighting the need for further study to understand its role in respiratory health.
