Lung Ultrasound in Patients with Acute Respiratory Failure Reduces Conventional Imaging and Health Care Provider Exposure to COVID-19.

Ultrasound Med Biol 2020 Aug 6;46(8):2090-2093. Epub 2020 May 6.

Anaesthesia and Intensive Care, San Matteo Hospital, Pavia, Italy; Department of Clinical-Surgical, Diagnostic and Pediatric Sciences, University of Pavia, Pavia, Italy.

Lung ultrasound gained a leading position in the last year as an imaging technique for the assessment and management of patients with acute respiratory failure. In coronavirus disease 2019 (COVID-19), its role may be of further importance because it is performed bedside and may limit chest X-ray and the need for transport to radiology for computed tomography (CT) scan. Since February 21, we progressively turned into a coronavirus-dedicated intensive care unit and applied an ultrasound-based approach to avoid traditional imaging and limit contamination as much as possible.

Are Chest Radiographs Routinely Indicated After Chest Tubes Placed for Non-Surgical Reasons Are Removed?

Cureus 2020 Mar 20;12(3):e7339. Epub 2020 Mar 20.

Pulmonary and Critical Care, Cleveland Clinic Florida, Weston, USA.

Background The insertion and subsequent removal of chest tubes are frequently performed procedures for the management of pneumothoraces, pleural effusions, and cardio-thoracic surgical interventions. A chest radiograph is commonly obtained after the removal of a chest tube to rule out the interval development of a pneumothorax. This practice has been questioned in various retrospective and prospective studies conducted on surgical patient populations, showing little to no benefits in performing routine chest X-rays (CXRs) after chest tube removal unless clinical symptoms such as worsening respiratory status and hemodynamic compromise are present.

Safe autologous rib harvest in patients with breast implants; technique and review.

JPRAS Open 2020 Jun 23;24:1-6. Epub 2020 Jan 23.

Otolaryngology and Facial Plastic Surgery Associates, Fort Worth, TX, United States.

Introduction: Autologous rib harvest is a useful technique for rhinoplasty when septal cartilage is inadequate. For patients who have previously undergone augmentation mammoplasty, however, there is theoretical concern about the risk to breast implant integrity during costal cartilage harvest The true risk to patients and their implants from autologous rib harvest is poorly studied Herein, we review our technique and experience with autologous rib harvest after augmentation mammoplasty.

Method: We performed a retrospective review of patients who underwent autologous rib harvest after augmentation mammoplasty between February 1998 and February 2017 at a tertiary care hospital and private practice. Read More
