Wheeze and Crackle Discrimination Algorithm in Pneumonia Respiratory Signals.

A new pneumonia detection method is proposed to provide both pneumonia detection in respiratory sound signals and wheeze and crackle discrimination when pneumonia episodes are detected. In the proposed method, two-step hierarchy, classifying pneumonia in the first step and discriminating wheezing and crackling in the second step, is considered; the conventional pneumonia detection method is modified to improve pneumonia detection performance, while wheezing and crackling discrimination functionality is added to facilitate the application of appropriate remedies for each case. We used resampling techniques to address the imbalance in the ICBHI pneumonia dataset.

Impact of lymph node evaluation standard in patients undergoing lung resection for clinical stage IA pulmonary adenocarcinoma and squamous cell carcinoma.

Background: The American College of Surgeons Commission on Cancer (CoC) revised operative quality standards recommending resection of lymph nodes from at least one hilar station and three different mediastinal stations in all curative-intent pulmonary resections. This study evaluated the prognostic value and factors associated with adherence to this new CoC standard in patients with resected clinical stage IA non-small cell lung cancer (NSCLC).

Methods: Retrospective review of 654 patients who underwent pulmonary resection for clinical IA NSCLC.

Laryngotracheal Resection for Idiopathic Subglottic Stenosis.

Idiopathic subglottic stenosis (ISS) is a rare disorder resulting in cicatricial narrowing of the airway centered at the cricoid cartilage. It almost exclusively affects Caucasian women. Endoscopic treatments such as dilatation, laser, or local injection of agents that can decrease the inflammatory and fibrotic reaction can be effective at palliating symptoms.

A Novel Prediction Method for Glaucoma Detection Using Retinographies.

Glaucoma, characterized by its damage to the retinal nerve, is one of the most statistically dominant eye diseases in the U.S. It can cause vision loss and blindness by affecting the optic nerve.
