Nivolumab-induced Diaphragm Dysfunction: A Case Report.

Unlabelled: Nivolumab is increasingly used in the treatment of melanoma. However, its use is associated with potentially severe side effects and every organ system can be affected. A case is presented where nivolumab therapy resulted in severe diaphragm dysfunction.

Monitoring of pulmonary involvement in critically ill COVID-19 patients - should lung ultrasound be preferred over CT?

Background: It is unclear if relevant changes in pulmonary involvement in critically ill COVID-19 patients can be reliably detected by the CT severity score (CTSS) and lung ultrasound score (LUSS), or if these changes have prognostic implications. In addition, it has been argued that adding pleural abnormalities to the LUSS could improve its prognostic value. The objective of this study was to compare LUSS and CTSS for the monitoring of COVID-19 pulmonary involvement through: first, establishing the correlation of LUSS (± pleural abnormalities) and CTSS throughout admission; second, assessing agreement and measurement error between raters for LUSS, pleural abnormalities, and CTSS; third, evaluating the association of the LUSS (± pleural abnormalities) and CTSS with mortality at different timepoints.

Video-assisted thoracic placement of epicardial leads.

Cardiac resynchronization therapy is one of the cornerstones of heart failure treatment. Inability to access the coronary sinus or one of its sidebranches is one of the most common causes of therapeutic failure. We describe a technique using video-assisted thoracic surgery for epicardial placement of the left ventricular lead and use an intrathoracic route to connect the lead to the device.
