BACKGROUND: Chronic traumatic encephalopathy (CTE), a neurodegenerative tauopathy, cannot currently be diagnosed during life. Atrophy patterns on magnetic resonance imaging could be an effective in vivo biomarker of CTE, but have not been characterized. Mechanisms of neurodegeneration in CTE...

BACKGROUND AND OBJECTIVES: Late neuropathologies of repetitive head impacts from contact sports can include chronic traumatic encephalopathy (CTE) and white matter degeneration. White matter hyperintensities (WMH) on fluid attenuated inversion recovery (FLAIR) MRI scans are often viewed as microvascular...

Point-of-care ultrasound (POCUS) is a critical skill for all regional anesthesiologists and pain physicians to help diagnose relevant complications related to routine practice and guide perioperative management. In an effort to inform the regional anesthesia and pain community as...

Characterization of Primary Mitral Regurgitation With Flail Leaflet and/or Wall-Impinging Flow.

Journal of the American College of Cardiology

Uretsky S, Morales DCV, Aldaia L, Mediratta A, Koulogiannis K, Marcoff L, Sakul S, Wolff SD, Gillam LD.

J Am Coll Cardiol. 2021 Dec 21;78(25):2537-2546. doi: 10.1016/j.jacc.2021.09.1382.

BACKGROUND: Echocardiography guidelines note that a flail leaflet is a specific criterion for severe mitral regurgitation (MR) and that regurgitant severity is underestimated in wall-impinging jets (Coandă effect). Both findings are often considered to be pathognomonic of severe MR.OBJECTIVES:...

We present a rare case of cardiogenic shock and multivessel coronary compression due to focal pericardial inflammation and constriction. The patient was treated in the acute phase with coronary stenting and temporary mechanical support. Multimodality imaging was essential in...

A Case Report of Incidental Hepatic Cysts Found on Ultrasound Imaging: Implications for the Anesthesiologist.

A&A practice

Point-of-care ultrasound imaging is increasingly used by anesthesiologists to facilitate rapid clinical diagnosis and treatment in the perioperative period. With its growing popularity, inevitably, unfamiliar structures will be observed. We present a case of cystic liver lesions in a...

Acute insertion effects of penetrating cortical microelectrodes imaged with quantitative optical coherence angiography.

Neurophotonics

Hammer DX, Lozzi A, Boretsky A, Welle CG.

The vascular response during cortical microelectrode insertion was measured with amplitude decorrelation-based quantitative optical coherence angiography (OCA). Four different shank-style microelectrode configurations were inserted in murine motor cortex beneath a surgically implanted window in discrete steps while OCA images...
