Impact of COVID-19 on patients undergoing scheduled procedures for chronic venous disease.

Objective: The COVID-19 pandemic has drastically altered the medical landscape. Various strategies have been employed to preserve hospital beds, personal protective equipment, and other resources to accommodate the surges of COVID-19 positive patients, hospital overcapacities, and staffing shortages. This has had a dramatic effect on vascular surgical practice.

The Accreditation Council for Graduate Medical Education 20-Year Trends in Diversity, Equity, and Inclusion in the United States: How Does Neurological Surgery Compare?

Background: Within the current medical workforce, diversity is limited among surgical specialties. However, diversity allows physicians to provide culturally competent care. This paper discusses the trends in racial, ethnic, and gender representation within different surgical subspecialties with an emphasis on neurosurgery over a 20-year time frame.

An Overview of Type B Lactic Acidosis Due to Thiamine (B1) Deficiency.

Type B lactic acidosis can occur secondary to several factors, including thiamine deficiency, and is not as common as type A. Recognizing thiamine deficiency-associated lactic acidosis is challenging because serum thiamine concentrations are not routinely obtained, and a thorough and specific history is necessary for clinicians to suspect thiamine deficiency as a root cause. Furthermore, the appropriate dose and duration of thiamine treatment are not well defined.

Investigation of intradetrusor onabotulinum toxin A efficacy and safety in older adults with urge urinary incontinence.

Purpose: Intradetrusor onabotulinum toxin A (BTX-A) has been demonstrated to be an effective treatment option for overactive bladder (OAB). However, concerns about frailty and frequent injections may deter its use in the elderly. This study aims to assess the safety, efficacy, and treatment duration of BTX-A in managing OAB in elderly women.

Preparation/administration of push-dose versus continuous infusion epinephrine and phenylephrine: A simulation.

Background: Hypotension is a common problem in the emergency department (ED) and intensive care unit (ICU) and can increase risk for poor outcomes. Many EDs/ICUs utilize epinephrine and phenylephrine to treat hypotension and these medications are most often administered as a continuous infusion (CI). Push-dose (PD) is the administration of small medication doses as intermittent intravenous pushes (IVPs).

Mechanisms of mRNA processing defects in inherited intellectual disability syndrome.

is the genetic basis of autosomal recessive THOC6 Intellectual Disability Syndrome (TIDS). THOC6 facilitates the formation of the Transcription Export complex (TREX) tetramer, composed of four THO monomers. The TREX tetramer supports mammalian mRNA processing that is distinct from yeast TREX dimer functions.

Head & Neck Trauma in the Geriatric Population.

Craniofacial trauma in the geriatric population is increasing as our population ages. Due to loss of bone quality and medical comorbidities, injuries for minor trauma can be severe. A more extensive medical evaluation is usually warranted in this population before proceeding with surgery.

Carotid Artery Operation Delay During the Covid-19 Pandemic: Results of a Multicenter International Study.

Background: To measure the impact of the COVID-19 pandemic on the management of patients with carotid artery stenosis.

Methods: We prospectively collected data from 25 centers (19 centers in the United States and 6 centers internationally) on postponed carotid artery operations between March 2020 and January 2022. We describe the characteristics of these patients and their planned operations, along with outcomes including mortality and neurological deterioration during the period of operative delay due to the COVID-19 pandemic.

Finding MRI features to obviate the need of repeat spinal biopsies in clinically suspected persistent or recurrent spinal osteomyelitis.

Purpose: The aim of this study was to determine magnetic resonance imaging (MRI) features that could help differen-tiate the bone destruction due to persistent/recurrent spine infection from worsening bone destruction due to mechanical factors, which could help obviate the need for repeat spine biopsy.

Material And Methods: A retrospective study was performed on selected subjects who were more than 18 years of age, were diagnosed with infectious spondylodiscitis, underwent at least 2 spinal interventions for the diagnosis at the same level, and had MRI prior to each image-guided intervention. Both MRI studies were analysed for vertebral body changes, paravertebral collections, epidural thickening and collections, bone marrow signal changes, loss of vertebral body height, abnormal signal in intervertebral disc, and loss of disc height.

Insidious onset of spontaneous spinal epidural hematoma in immune thrombocytopenic purpura: a case-based review.

Introduction: Spontaneous spinal epidural hematoma (SSEH) can result from various etiologies with a variable degree of neurological deficits. Here, we describe a rare case of SEH secondary to immune thrombocytopenic purpura (ITP) in a child and review the literature of SSEH caused by ITP.

Case Report: A 9-year-old female who presented with rapid neurological decline, including bowel and bladder incontinence and paraparesis.
