A novel gene fusion variant in lung adenocarcinoma with prolonged response to tepotinib: a case report.

Background: rearrangements are infrequently observed in non-small cell lung cancer (NSCLC). Advanced genomic detection techniques have unveiled such infrequent genomic variations, particularly fusions in approximately 0.5% of NSCLC patients.

Computational fluid dynamics evaluation of excessive dynamic airway collapse.

Background: Excessive dynamic airway collapse, which is often caused by the collapse of the posterior membrane wall during exhalation, is often misdiagnosed with other diseases; stents can provide support for the collapsing airways. The standard pulmonary function tests do not necessarily show change in functional breathing condition for evaluation of these type of diseases.

Methods: Flow characteristics through a patient's airways with excessive dynamic airway collapse have been numerically investigated.

Teflon Injection into the Trachea Causes Predictable Fibroblastic Response and Collagen Deposition: A Pilot Study.

Background: Expiratory central airway collapse is an increasingly recognized abnormality of the central airways and may be present in as many as 22% of patients evaluated for chronic obstructive pulmonary disease and/or asthma. Many current treatment options require invasive procedures that have been shown to cause significant morbidity and mortality. To test the hypothesis that Teflon injection will induce sufficient fibroblast proliferation and collagen deposition, we evaluated the time course on the effect of Teflon injection in the posterior membranous trachea on the histopathology of the tracheobronchial tree.

Successful closure of bronchopleural fistula with Xeroform dressing.

Bronchopleural fistula (BPF) is a communication between the pleural space and the bronchial tree, and is associated with significant morbidity and mortality. Treatment options for BPF include surgical closure and medical therapy. In an unstable patient, invasive surgical intervention is not an option.

Office microlaparoscopy for female sterilization under local anesthesia. A cost and clinical analysis.

Objective: To evaluate the clinical and cost effectiveness of permanent female sterilization using microlaparoscopy and bipolar cauterization. The authors also tested how well the procedure was tolerated when performed under local anesthesia and conscious sedation.

Study Design: Patients undergoing microlaparoscopic permanent sterilization were prospectively followed.
