We describe an elastographic method to circumferentially-resolve airway wall compliance using endoscopic, anatomic optical coherence tomography (aOCT) combined with an intraluminal pressure catheter. The method was first demonstrated on notched silicone phantoms of known elastic modulus under respiratory ventilation, where localized compliance measurements were validated against those predicted by finite element modeling. Then, ex vivo porcine tracheas were scanned, and the pattern of compliance was found to be consistent with histological identification of the locations of (stiff) cartilage and (soft) muscle. This quantitative method may aid in diagnosis and monitoring of collapsible airway wall tissues in obstructive respiratory disorders.
We present a case of tracheal necrosis due to mucormycosis in a young diabetic male. He presented with stridor due to airway obstruction from the necrosed tracheal wall. We used a silicon tracheal stent to maintain airway patency and support the airway.

Objectives: To investigate the diagnostic value of CT lymphangiography (CTL) and non-contrast MR lymphangiography (MRL) in lymphatic plastic bronchitis.
Materials And Methods: The clinical and imaging data of 31 patients with lymphatic plastic bronchitis diagnosed by clinical, imaging and pathological results were retrospectively analyzed. All patients underwent CTL and MRL.
Objectives: Present a clinically challenging case of an immunocompetent 74-year-old male who presented with marked dyspnea and hemoptysis. After the airway was secured, direct laryngoscopy revealed a large, fungating, hemorrhagic mass of the left lateral pharyngeal wall and surrounding structures.
The Denver shunt is used for persistent chylothorax as a pleuroperitoneal shunt. Insertion of a Denver shunt was attempted in the current case involving a 3-year-old male with a refractory right cervical mediastinal lymphangioma. He was medicated with Eppikajutsuto® (0.
Ethnopharmacological Relevance: Danlong oral liquid (DLOL) is a traditional Chinese proprietary medicine commonly used to treat chronic respiratory diseases, including bronchial asthma and chronic obstructive pulmonary disease. However, the therapeutic effects and pharmacological mechanisms of DLOL in improving airway remodeling remain unclear.
Aims Of The Study: This study utilizes in vivo and in vitro experiments, serum pharmacological analysis, and network-based pharmacology approaches to investigate the effects and mechanisms of DLOL on airway remodeling and epithelial-mesenchymal transition (EMT) in asthma.
