While lung ultrasonography (LUS) proved to be a useful diagnostic and prognostic tool in acute phase of COVID 19 pneumonia, its role in detecting long-term pulmonary sequelae has yet to be explored. In our prospective observational study we assessed the potential of LUS in detecting the presence of computed tomography (CT) fibrotic-like changes after 6 months from COVID-19 pneumonia. Patients who were discharged with a diagnosis of severe COVID-19 pneumonia were enrolled. After 6 months from hospital discharge they underwent LUS, chest CT scan and pulmonary function tests. A logistic regression analysis was performed to assess the association between presence of symptoms, LUS score and diffusing capacity for carbon monoxide (DLCO) at 6-month after hospital discharge and CT scan fibrotic-like changes. A second logistic model was performed to assess the value of some predefined baseline factors (age, sex, worst PaO2/FiO2, ventilator support, worst CRP value, worst D-dimer value and worst LUS score during hospitalization) to predict fibrotic-like changes on 6-month CT scan. Seventy-four patients were enrolled in the study. Twenty-four (32%) showed lung abnormalities suitable for fibrotic-like changes. At multivariate logistic regression analysis LUS score after 6 months from acute disease was significantly associated with fibrotic-like pattern on CT scan. The second logistic model showed that D-dimer value was the only baseline predictive variable of fibrotic-like changes at multivariate analysis. LUS performed after 6 months from severe COVID-19 pneumonia may be a promising tool for detection and follow-up of pulmonary fibrotic sequelae.

A 48-year-old female presented to the emergency department with chest pain and collapsed at the front desk. She was reanimated with mechanical chest compression, and after coronary angiography, a left anterior descending/diagonal bifurcation mini-crush stenting was performed. Few hours after the procedure, the patient showed severe hypotension. Abdominal ultrasound and computed tomography (CT) scan evidenced a massive subcapsular liver hematoma (Grade IV, American association for the surgery of trauma (AAST) liver injury scale) of the right lobe with extrahepatic blushing. Transhepatic embolization was attempted but without benefit, so the patient underwent emergency laparotomy for damage control surgery with perihepatic packing. After hemodynamic stabilization, right hepatectomy was performed with a favorable outcome and full recovery. The patient CT scan was retrospectively processed to obtain a virtual model visualizable through a head-mounted display. The virtual reconstruction could improve the comprehension of the injury and the liver surgical anatomy for educational purpose, and it could represent a new tool for preoperative planning.

Background Emergency Department Thoracotomy (EDRT) after traumatic Cardio-pulmonary Arrest (CPR) can be used to salvage select critically injured patients. Indications of this surgical procedure are widely debated and changed during last decades. We provide the available literature about EDRT in the effort to provide a comprehensive synthesis about the procedure, likelihood of success and patient’s outcome in the different clinical setting, accepted indications and technical details adopted during the procedure for different trauma injuries. Methods Literature from 1975 to 2020 was retrieved from multiple databases and reviewed. Indications, contraindications, total number and outcome of patients submitted to EDRT were primary endpoints. Results A total number of 7236 patients received EDRT, but only 7.8% survived. Penetrating trauma and witnessed cardiopulmonary arrest with the presence of vital signs at the trauma center are the most favorable conditions to perform EDRT. Conclusions EDRT should be reserved for acute resuscitation of selected dying trauma patient. Risks of futility, costs, benefits of the surgical procedure should be carefully evaluated before performing the surgical procedure.

IntroductionThe course of Anatomy in Vialba Medical School - University of Milan, integrates systemic, topographic and development anatomy, dissection laboratory, peer-teaching, flipped classroom, clinical correlation to radiology and surgery.MethodsAn anonymous questionnaire based on a five-point Likert scale was submitted to 162 students who had passed the exam of Anatomy. Students evaluated the importance given during study to morphology, relations and variations of organs, the usefulness of different tools in preparing the exam of anatomy. Finally, the impact of the new design course of Anatomy on students' progress was assessed.ResultsThe results showed that most of the students found very useful dissections, multimedia sources and 3D virtual models. 3D virtual models, dissections and physical models were indicated as the most important tools that should be available for learning Anatomy; instead, medical imaging received a low score. Students focused the study on morphology and relations between organs much more than anatomical variations. Lastly, students who followed the new design course of anatomy showed a significant better performance when compared to students of the previous academic years, in particular on the anatomy of neck, thoracic and abdominopelvic cavity, and neuroanatomy.ConclusionsOur study underlines the positive impact of the integration of traditional methods and innovative solutions in learning anatomy, but also the critical approach to radiologic imaging and anatomical variability.
