Dry needling (DN) is a minimally invasive treatment technique widely used by physical therapists to treat myofascial trigger points (MTrP). Even if its safety has been commonly declared and the majority of adverse events are considered mild, serious adverse events cannot be excluded and DN treatments of several trunk muscles can potentially result in pneumothorax. Ultrasound imaging (US) skin-to-rib measurement could ensure the safety of this treatment procedure. Read More

The new disease outbreak that causes atypical pneumonia named COVID-19, which started in China's Wuhan province, has quickly spread to a pandemic. Although the imaging test of choice for the initial study is plain chest radiograph, CT has proven useful in characterizing better the complications associated with this new infection. We describe the evolution of 3 patients presenting pneumomediastinum and spontaneous pneumothorax as a very rare complication of COVID-19 and their particular interest as a probable prognostic factor.

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.

Introduction: It is traditionally taught that the location to place an ultrasound probe to detect a pneumothorax with point-of-care ultrasound (POCUS) is the anterior chest, given the theory that air will collect at the least dependent area in the supine patient. There is a wide variety of scanning protocols with varying accuracy and completeness. We sought to assess the optimal area to scan for diagnosing pneumothorax by mapping the location of traumatic pneumothorax on computed tomography (CT). Read More

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.
