Retrospective analysis of 1028 ultrasound-guided central vascular access in neonates and children.

Background: The use of real-time ultrasound has become the standard of care for percutaneous central venous access and shown to decrease overall number of attempts and complication rates.

Material And Method: A retrospective analysis of a prospective database was done focusing on three types of central access: non-tunneled, tunneled, and implantable, placed via ultrasound-guided Brachiocephalic Vein (BCV) between January 2019 and January 2023. Data were recorded: gender, age, weight, side (left or right), number of puncture attempts, arterial puncture, change of operator or puncture side, and mechanical complications (pneumothorax and hemothorax).

MRI identification of pseudolesions in the distal tibia articular surface: Frequency and diagnostic criteria.

Objective: Pseudolesions of joints are known as focal irregularities of chondral or subchondral bone in typical joint areas and occur frequent but without clinical relevance. This study aims to report the prevalence and describe MRI findings of a previously unreported chondral, mostly posterior located pseudolesion of the distal tibia, and to define criteria to distinguish it from pathologic osteochondral lesions, as well as from another known pseudolesion of this area - the so called "Notch of Harty".

Material And Methods: A tri-centric retrospective case-control study included a total of 2,428 patients with ankle MRI examinations performed over a period of 6 years.

The genome of a bunyavirus cannot be defined at the level of the viral particle but only at the scale of the viral population.

Bunyaviruses are enveloped negative or ambisense single-stranded RNA viruses with a genome divided into several segments. The canonical view depicts each viral particle packaging one copy of each genomic segment in one polarity named the viral strand. Several opposing observations revealed nonequal ratios of the segments, uneven number of segments per virion, and even packaging of viral complementary strands.

Symptomatic pancreatic lipoma managed with a metallic biliary stent: Case report.

Introduction: Mesenchymal tumors comprise only 1 to 2% of all pancreatic tumors, being lipomas a rare variant of mesenchymal tumors of the pancreas.

Presentation Of Case: This is the report of an 82-year-old woman who presented at the medical emergency room in a fourth level clinic with five days of nausea evolution, emesis, jaundice, coluria, acholia, and abdominal pain in the right hypochondrium. Diagnostic imaging and ultrasonography discovered and characterized a significant dilation of the intra and extrahepatic bile duct, caused by the presence of a mass in the head of the pancreas of lipomatous origin.

Counterintuitive Pseudoscience Propagates by Exploiting the Mind's Communication Evaluation Mechanisms.

Epidemiological models of culture posit that the prevalence of a belief depends in part on the fit between that belief and intuitions generated by the mind's reliably developing architecture. Application of such models to pseudoscience suggests that one route via which these beliefs gain widespread appeal stems from their compatibility with these intuitions. For example, anti-vaccination beliefs are readily adopted because they cohere with intuitions about the threat of contagion.
