Clinical and Imaging Outcomes of Surgically Repaired Cerebrospinal Fluid-Venous Fistulas Identified by Lateral Decubitus Digital Subtraction Myelography.

Objective: To describe clinical and radiographic outcomes of surgical repair of cerebrospinal fluid-venous fistula (CVF), an increasingly recognized cause of spontaneous intracranial hypotension that is poorly responsive to epidural blood patch (EBP).

Methods: Retrospective review identified adult patients who had lateral decubitus digital subtraction myelography indicative of cerebrospinal fluid leak at Mayo Clinic between November 2018 and February 2020, with clearly localized CVF, followed by surgical treatment. Patients without available imaging before or after surgery were excluded.

Cerebral Function and Muscle Afferent Activity Following Intravenous Succinylcholine in Dogs Anesthetized with Halothane: The Effects of Pretreatment with a Defasciculating Dose of Pancuronium. By WL Lanier, PA Iaizzo, and JH Milde. Anesthesiology 1989; 71:87-95.

Pituitary Tumor Surgery: Comparison of Endoscopic and Microscopic Techniques at a Single Center.

Objective: To understand the transition from microscopic surgery (MS) to endoscopic surgery (ES) on the pituitary across the United States, we assessed a single institution practicing both procedures to discern advantages and disadvantages for each.

Patients And Methods: Retrospective institutional chart review of 534 patients in a large practice over a 6-year period (January 1, 2014, to December 31, 2019) comparing a single MS neurosurgeon with a single ES neurosurgeon operating on the same days.

Results: In this series, 14% (n=75) of patients had a prior operation, there were no carotid artery injuries, the overall risk for a postoperative infection was 0.

Dealing with inappropriate-, low-quality-, and other forms of challenging peer review, including hostile referees and inflammatory or confusing critiques: Prevention and treatment.

Within the context of journal peer review, when high-quality referee input is coupled with appropriate editorial oversight from a journal's leadership, the result can be the selection and publication of high-quality manuscripts that are ideally targeted to the journal's readership's interests. However, in its worse forms, flawed referee input and indifferent- or misdirected journal leadership can result in damage to the quality of materials published and the relationships among, and careers of, the involved parties. This article identifies methods that journals can employ to select journal leaders and educate authors, referees, and editors in an attempt to prophylax against problematic peer review.

Evidence versus advocacy, as related to radiofrequency denervation in the treatment of chronic low back pain and the MINT trials.

In 2017, published the results of the MINT trials, prospective research involving 681 patients, all of whom received exercise therapy for low back pain. Half of the patients were randomized to additionally receive radiofrequency denervation (RFD) treatment. 88% of patients completed the 3-month follow-up, and 77% completed the 12-month follow-up.

Effect of Promotion via Social Media on Access of Articles in an Academic Medical Journal: A Randomized Controlled Trial.

Purpose: To study the effect of a planned social media promotion strategy on access of online articles in an established academic medical journal.

Method: This was a single-masked, randomized controlled trial using articles published in Mayo Clinic Proceedings, a large-circulation general/internal medicine journal. Articles published during the months of October, November, and December 2015 (n = 68) were randomized to social media promotion (SoMe) using Twitter, Facebook, and LinkedIn or to no social media promotion (NoSoMe), for 30 days (beginning with the date of online article publication).

Hydraulic stimulation of carotid artery baroreceptors as a likely cause of transient asystolic cardiac arrest during diagnostic angiography or surgical endarterectomy.

We describe two patients-both who underwent general anesthesia-in whom we theorize that hydraulic pressure on carotid artery baroreceptors resulted in transient asystolic cardiac arrest (TACA) during diagnostic or therapeutic procedures. Patient #1 was a 58-year-old female who experienced TACA in response to rapid injection of radiocontrast material into the carotid artery during diagnostic cerebral angiography. Her history was remarkable for aneurysmal subarachnoid hemorrhage at least 13 hr prior to angiography, radiographic evidence of intracranial hypertension, and baseline bradycardia, collectively suggestive of increases in baseline vagal tone.

Flick-Spin Methodology for Improving Cannulation Success in Tortuous and Valve-Rich Peripheral Veins.

Peripheral veins often contain tortuosities and valves that hinder the effective passage of intravenous catheters to the full extent of catheter length. This report describes a methodology termed that has proven efficacious for venous catheter passage in tortuous and valve-rich peripheral veins. The method relies on (1) applying longitudinal tension to the vessel in an attempt to straighten it, (2) rotating or spinning the catheter along its longitudinal axis, and (3) flicking the skin or visible vein just beyond the catheter tip, all during catheter advancement.

Neuroanesthesiology Update.

We provide a synopsis of innovative research, recurring themes, and novel experimental findings pertinent to the care of neurosurgical patients and critically ill patients with neurological diseases. We cover the following broad topics: general neurosurgery, spine surgery, stroke, traumatic brain injury, monitoring, and anesthetic neurotoxicity.

Real-Time Cineangiography Visualization of Cerebral Aneurysm Rupture in an Awake Patient: Anatomic, Physiological, and Functional Correlates.

Intracranial aneurysms are common and, on a population-based perspective, are a major cause of morbidity and mortality as a result of mass effect or rupture. Cerebral angiography is the primary technique used for the diagnosis of cerebral aneurysms, and the imaging data have additional utility for planning medical, endovascular, or surgical treatments. An extremely rare periprocedural complication of cerebral angiography is rupture of the aneurysm, either as a chance phenomenon or as a result of some physiologic change or mechanical effect.

Exposure to Surgery and Anesthesia After Concussion Due to Mild Traumatic Brain Injury.

Objective: To describe the epidemiology of surgical and anesthetic procedures in patients recently diagnosed as having a concussion due to mild traumatic brain injury.

Patients And Methods: Study patients presented to a tertiary care center after a concussion due to mild traumatic brain injury from July 1, 2005, through June 30, 2015, and underwent a surgical procedure and anesthesia support under the direct or indirect care of a physician anesthesiologist.

Results: During the study period, 1038 patients met all the study inclusion criteria and subsequently received 1820 anesthetics.

Neuroanesthesiology Update.

We reviewed manuscripts published in 2016 that are related to the care of neurosurgical patients or the perioperative care of patients with neurological diseases. We address the broad categories of general neurosurgery and neuroanesthesiology, anesthetic neurotoxicity and neuroprotection, stroke, traumatic brain injury, and nervous system monitoring.

Perianesthetic Management of Patients With Thyroid-Stimulating Hormone-Secreting Pituitary Adenomas.

Background: Thyroid-stimulating hormone (TSH)-secreting pituitary adenomas are a rare cause of secondary hyperthyroidism. Anesthetic management of these patients has not been formally described in the literature.

Materials And Methods: Patients who underwent resection of a TSH-secreting pituitary adenoma during 1987 to 2012 at a single institution were identified.

Neuroanesthesiology Update.

We provide a synopsis of innovative research, recurring themes, and novel experimental findings pertinent to the care of neurosurgical patients and critically ill patients with neurological diseases. The following broad topics are covered: general neurosurgery, spine surgery, stroke, traumatic brain injury, anesthetic neurotoxicity, perioperative cognitive dysfunction, and monitoring.
