Rationale: Airflow obstruction refractory to β2 adrenergic receptor (β2AR) agonists is an important clinical feature of infant respiratory syncytial virus (RSV) bronchiolitis, with limited treatment options. This resistance is often linked to poor drug delivery and potential viral infection of airway smooth muscle cells (ASMCs). Whether RSV inflammation causes β2AR desensitization in infant ASMCs is unknown.

Pleomorphic adenoma of the trachea is a rare benign tumor, often challenging to diagnose due to nonspecific symptoms. We report a case of a 72-year-old female with a 10-year history of presumed bronchial asthma, presenting with persistent dyspnea. Preoperative assessment for breast cancer surgery revealed severe obstructive ventilatory impairment.

Septic arthritis of the sternoclavicular joint is a rare infectious arthritis in which the risk factors are reported to be such as diabetes, immunosuppression, and intravenous drug use. Due to a lack of prominent symptoms, delayed diagnosis can lead to severe complications such as mediastinitis and empyema. Advanced sternoclavicular septic arthritis can be a hidden etiology masked by severe symptoms.

The tumor microenvironment (TME) plays a crucial role in the progression of lung adenocarcinoma (LUAD). However, understanding its dynamic immune and stromal modulation remains a complex challenge. We utilized the ESTIMATE algorithm to evaluate the immune and stromal components of the LUAD TME from the TCGA database.
