The authors present the case report of a pediatric patient with a ruptured traumatic pseudoaneurysm of the intracranial vertebral artery (VA) from which the posterior inferior cerebellar artery (PICA) emerged. After considering multiple therapeutic options, the patient was treated surgically by trapping of the aneurysm segment and direct reimplantation of the PICA distal to the rupture site. In addition to presenting this unique case, the authors discuss the treatment of VA pseudoaneurysms and the various techniques for PICA revascularization. A review of the literature on PICA reimplantation is provided as an adjunct in the treatment of complex VA aneurysms.

Department of Ophthalmology, Rutgers New Jersey Medical School, Institute of Ophthalmology and Visual Science, Newark, NJ, USA.
Purpose: The purpose of this study is to analyze the trends and characteristics of ocular trauma research published from 2000 to 2022 to delineate the trajectory of the field's research, provide information about the network of key contributors, and help determine future research strategies and direction.
Methods: Web of Science was queried for published works using a series of keywords relating to ocular trauma: "globe rupture", "ruptured globe", "globe injury", "ocular trauma", "intraocular foreign body", "eye trauma", "eye injury", and "traumatic endophthalmitis". All article information was compiled using the VOSviewer software.

Our patient presented to the emergency room following a motor vehicle accident. The traumatic tricuspid valve rupture was diagnosed by transthoracic echocardiogram, and his respiratory status declined rapidly. He was placed on veno-venous extracorporeal membrane oxygenation (VV ECMO) to bridge him to surgical repair.

Introduction: This review aims to synthesise research evidence regarding biomarkers in the synovial fluid that may predict the risk of post-traumatic osteoarthritis (PTOA) in young adults. Considering the high prevalence of knee joint injuries, particularly among youth sports athletes, this review will focus on anterior cruciate ligament and/or meniscal ruptures. These injuries are highly associated with PTOA, with studies indicating that even with surgical reconstruction, 50%-80% of affected individuals develop knee PTOA within a 10-year follow-up.

Although peritonitis is highly prevalent in cattle, there have been only limited studies on the pathology of this condition. We describe the gross and histological aspects of primary and secondary peritonitis in cattle based on necropsy reports of 46 cases. Twenty-six were female (26/46; 56.

Background: Hybrid emergency rooms (ERs) allow computed tomography (CT) scanning, interventional radiology, and surgery all in the same suite. Severe trauma patients with blunt thoracic aortic injury (BTAI) require rapid diagnosis and treatment. Hybrid ERs allow the potential for clinicians to implement multiple therapeutic procedures, including thoracic endovascular aortic repair (TEVAR), for these types of conditions without the need to transport the patients.
