Evaluation of Seizure Risk in Infants After Cardiopulmonary Bypass in the Absence of Deep Hypothermic Cardiac Arrest.

Neurocrit Care 2021 Jul 28. Epub 2021 Jul 28.

Division of Child Neurology, Lucile Packard Children's Hospital at Stanford University, Dr Levy 750 Welch Road Suite 317, Palo Alto, CA, USA.

Background: Guidelines recommend evaluation for electrographic seizures in neonates and children at risk, including after cardiopulmonary bypass (CPB). Although initial research using screening electroencephalograms (EEGs) in infants after CPB found a 21% seizure incidence, more recent work reports seizure incidences ranging 3-12%. Deep hypothermic cardiac arrest was associated with increased seizure risk in prior reports but is uncommon at our institution and less widely used in contemporary practice. Read More

Glenohumeral osteoarthritis with intact rotator cuff treated with reverse shoulder arthroplasty: a systematic review.

J Shoulder Elbow Surg 2021 Jul 19. Epub 2021 Jul 19.

Division of Upper Extremity Surgery, Department of Orthopaedic Surgery, Director of Upper Extremity Surgery Research, Emory University 59 Executive Park South, Atlanta, GA 30329, USA.

Medial Unicompartmental Knee Arthroplasty with a Mobile-Bearing Implant.

JBJS Essent Surg Tech 2021 Apr-Jun;11(2). Epub 2021 Apr 19.

Department of Orthopaedic Surgery, Stanford Hospital and Clinics, Redwood City, California.

Background: For patients with isolated medial knee arthritis, unicompartmental knee arthroplasty (UKA) is an appealing surgical option. Compared with total knee arthroplasty (TKA), UKA is less invasive, preserves more native bone stock, has lower perioperative morbidity and mortality, allows for quicker recovery, and has higher patient satisfaction. It also allows for more dynamic proprioception and postural control, allowing for function more similar to a native knee. Read More
