Usefulness of endobronchial ultrasound (EBUS) in the diagnosis of peripheral pulmonary lesions in a general hospital.

Aim: To investigate the efficiency of guided bronchoscopy compared to blind techniques in the study of non-visible pulmonary lesions.

Materials And Methods: A one-year, retrospective, study was conducted comparing two populations: Biopsies were either performed conventionally (FB-B) with the help of static images and the second where biopsies were performed after guidance (FB-EBUS). A 20-MHz radial-type ultrasound probe was used to obtain images.

The role of endobronchial ultrasound in lung cancer diagnosis and staging: a comprehensive review.

Endobronchial ultrasound (EBUS) technology is a relatively new bronchoscopic method of visualizing the tracheobronchial tree, the surrounding pulmonary parenchyma, and the mediastinal structures, with a particular role in lung cancer diagnosis, staging, and treatment. There are 2 types of probes used in EBUS: the peripheral or radial probe (RP) and the linear or convex probe (CP) EBUS, which have technical differences and distinct diagnostic abilities. Both are used for EBUS-guided biopsies and transbronchial needle aspirations (TBNA), which increases the diagnostic yield over conventional bronchoscopic techniques, thus providing advanced information on staging, diagnosis, and treatment.

Fatal Hemoptysis due to Chronic Cavitary Pulmonary Aspergillosis Complicated by Nontuberculous Mycobacterial Tuberculosis.

A 51-year-old man, with a history of severe COPD and bilateral pneumothorax, who was under treatment for pulmonary tuberculosis due to mycobacterium avium, was admitted due to high-grade fever, weight loss, cough, and production of purulent sputum, for almost one month without any special improvement despite adequate antibiotics treatment in outpatient setting. A CT scan revealed multiple consolidations, fibrosis, scaring, and cavitary lesions in both upper lobes with newly shadows which were fungus balls inside them. Aspergillus flavius was isolated in three sputum samples, a diagnosis of chronic cavitary pulmonary aspergillosis was made, and treatment with intravenous amphotericin B was started.

Potential interaction between telithromycin and warfarin.

Objective: To report a case of warfarin-telithromycin interaction resulting in an elevated international normalized ratio (INR) and hemoptysis.

Case Summary: A 73-year-old white man developed an elevated INR and mild hemoptysis as a result of an interaction between warfarin and telithromycin 800 mg/day. The INR increased from 3.
