Beyond the Wada: An updated approach to pre-surgical language and memory testing: An updated review of available evaluation techniques and recommended workflow to limit Wada test use to essential clinical cases.

Epilepsy Res 2021 Aug 15;174:106673. Epub 2021 May 15.

Epilepsy Division, Department of Neurology, University of Texas Southwestern Medical Center Dallas. Electronic address:

The Intracarotid amobarbital test (IAT), also called Wada test, is considered the "gold standard" for lateralizing language dominance in the pre-surgical evaluation of patients with epilepsy. In addition, it has been further modified to assess the postoperative risk of amnesia in patients undergoing temporal lobectomy. Since then it has been utilized to lateralize language and assess pre-surgical memory function. Read More

Analysis of Long-Term Outcomes Following Surgical Contracture Release of the Elbow: A Case Series.

Cureus 2021 Apr 26;13(4):e14691. Epub 2021 Apr 26.

Orthopaedics, Penn State Health Milton S. Hershey Medical Center, Hershey, USA.

Background Elbow contracture is a debilitating condition with an incidence ranging from as low as almost 1% to as high as 20% and results in significant limiting consequences on a patient's activities of daily living (ADLs). Postoperative rehabilitation is important in maintaining the range of motion and sustaining an improved range of motion. The purpose of this study was to evaluate the long-term results of elbow contracture release surgery and the effect of an occupational therapy/physical therapy (OT/PT)-guided, self-directed rehabilitation program following surgery, without the use of continuous passive motion (CPM) devices.

Prevalence of Anti-HBc Antibodies among HBsAg Negative Individuals and Its Association with Occult Hepatitis B.

J Lab Physicians 2021 Mar 19;13(1):1-5. Epub 2021 May 19.

Department of Microbiology, Government TD Medical College, Alappuzha, Kerala, India.

 Hepatitis B virus (HBV) infection is an endemic in many Asian countries, and among the major routes of transmission, transfusion is the one that should be prevented. Occult HBV infection (OBI) is defined as the presence of HBV DNA in the absence of detectable HBsAg, with or without anti-HBV antibodies. The aim of this study was to detect the prevalence of anti-HBc total antibodies among the HB surface antigen (HBsAg) negative individuals by way of enzyme-linked immunosorbent assay (ELISA), and detect the presence of HBV DNA among the anti-HBc seropositives by polymerase chain reaction (PCR).

Economic Burden of Patient-Reported Penicillin Allergy on Total Hip and Total Knee Arthroplasty.

J Arthroplasty 2021 Sep 4;36(9):3067-3072. Epub 2021 May 4.

Department of Orthopaedic Surgery, Tulane University School of Medicine, New Orleans, LA.

Introduction: Self-reported penicillin allergies in patients undergoing total joint arthroplasty often results in the use of second-line prophylactic antibiotics. A higher risk of prosthetic joint infection (PJI) is associated with suboptimal antibiotics vs first generation cephalosporins, which have historically been grouped with other beta-lactam antibiotics such as penicillin for potential allergic reactions. This study evaluates the economic burden of self-reported penicillin allergies in total joint arthroplasty (TJA). Read More

J Neurosurg 2021 May 28:1-8. Epub 2021 May 28.

1Department of Neurological Surgery, University of California, San Francisco, California; and.

Objective: Intraoperative tasks for awake language mapping are typically selected based on the language tracts that will likely be encountered during tumor resection. However, diminished attention and arousal secondary to perioperative sedatives may reduce a task's usefulness for identifying eloquent cortex. For instance, accuracy in performing select language tasks may be high preoperatively but decline in the operating room. Read More

Machine learning for predicting preoperative red blood cell demand.

Transfus Med 2021 Aug 24;31(4):262-270. Epub 2021 May 24.

Department of Transfusion Medicine, The First Medical Center of Chinese PLA General Hospital, Beijing, China.

Am J Infect Control 2021 10 19;49(10):1322-1323. Epub 2021 May 19.

Department of Infection Prevention, Emory University Hospital, Midtown. Atlanta, GA. Electronic address:

Early in the pandemic, infection prevention (IP), in collaboration with our local anesthesia leadership, took the approach of ensuring all members of the Anesthesia Department understood the importance of universal masking, were individually trained on the use of the Controlled Air Purifier Respirator, as well the appropriate method for donning/doffing N95 respirators. Multiple providers in the department tested positive for COVID, resulting in the IP Department to conduct the routine contact tracing investigation. During the investigation, it was determined that all persons who met the CDC (Centers for Disease Control & Prevention) contact exposure guidelines would undergo COVID testing, which consequently was 109 team members due to the exposure risk identified in the break room space.
