Feasibility and Safety of Transesophageal Mediastinal Cryobiopsy in the Diagnosis of Mediastinal Pathologies.

Introduction: Endobronchial ultrasound-guided transbronchial needle aspiration remains the gold standard for the diagnosis of mediastinal pathologies. Its greatest limitation has been the low diagnostic yield in lymphoproliferative disorders as well as insufficient samples for molecular testing. Transesophageal examinations using an EBUS scope have helped increase the diagnostic yield by allowing for additional biopsies of paraesophageal and intra-abdominal lesions.

Lung Ultrasound Effectively Detects HIV-Associated Interstitial Pulmonary Disease.

Objectives To prospectively evaluate lung ultrasound in comparison with radiography and computed tomography (CT) for detecting HIV-related lung diseases. Methods Ultrasound examinations in HIV-positive patients were evaluated by three raters; available conventional imaging was evaluated by another rater. Results were compared with each other and the definite diagnosis.
