Point-of-Care Ultrasound Protocol for Insertion and Confirmation of Central Venous Catheter Placement.

Central venous catheterization is a common procedure in the management of critically ill patients, in the context of medical emergencies, and before surgical interventions. Placing a central venous catheter (CVC) in the internal jugular vein (IJV) using anatomical references is associated with a high risk of complications, in particular pneumothorax and arterial puncture. Thus, the placement of CVCs with ultrasound support is recommended by several medical societies and health regulators at the international level. When compared with chest radiography, ultrasound is accessible, safe, cost-effective, and time efficient. This technical report is meant to detail a point-of-care ultrasound protocol designed for the insertion and confirmation of the correct placement of a CVC in the IJV.

Non-bacterial Thrombotic Endocarditis as a Rare Manifestation of Early Stage Gastric Cancer.

Endocarditis is an inflammation of the endocardium and is characterized by the presence of vegetation, which may occur in the context of infectious or non-infectious diseases. Despite the higher rate of infective endocarditis diagnosis, it may also surge in other non-infectious conditions such as cancer or chronic inflammatory syndromes. Cancer defines a hypercoagulable state, and cancer-associated thrombophilia can have a diverse clinical presentation, most commonly venous thromboembolism and rarely non-bacterial thrombotic endocarditis (NBTE). The diagnosis of NBTE is difficult and requires a high level of suspicion. The treatment relies on anticoagulant therapy, control of underlying disease, and valve replacement when applied. Independently of the etiology, without treatment, endocarditis may lead to valve dysfunction and to the worst prognosis. In this paper, we describe a case of a patient with persistent fever and NBTE of the tricuspid valve, disclosing a rare presentation of gastric cancer.
