Bidirectional brain-gut interactions and chronic pathological changes after traumatic brain injury in mice.

Brain Behav Immun

November 2017

Department of Anesthesiology and Shock, Trauma and Anesthesiology Research (STAR) Center, University of Maryland School of Medicine, Baltimore, MD, USA. Electronic address:

Objectives: Traumatic brain injury (TBI) has complex effects on the gastrointestinal tract that are associated with TBI-related morbidity and mortality. We examined changes in mucosal barrier properties and enteric glial cell response in the gut after experimental TBI in mice, as well as effects of the enteric pathogen Citrobacter rodentium (Cr) on both gut and brain after injury.

Methods: Moderate-level TBI was induced in C57BL/6mice by controlled cortical impact (CCI).

The brain and heart are two vital systems in health and disease, increasingly recognized as a complex, interdependent network with constant information flow in both directions. After severe traumatic brain injury (TBI), the causal, directed interactions between the brain, heart, and autonomic nervous system have not been well established. Novel methods are needed to probe unmeasured, potentially prognostic information in complex biological networks that are not revealed by traditional means.

Aim: The objective was to compare the recurrent laryngeal nerve (RLN) and superior laryngeal nerve (SLN) injuries in patients with bilateral total thyroidectomy (BTT) and bilateral near total thyroidectomy (BNTT) with the frequency of the hypocalcemic complications regarding the operation procedures.

Materials And Methods: Patients, who underwent BTT and BNTT in our clinic between January 1999 and January 2011, were included in this retrospective clinical study. Patients' files are evaluated.

Background: Diabetes mellitus may cause degeneration in the myelin and/or axonal structures of peripheral nerves. The aim of this study was to investigate the effects of diabetic neuropathy on intraoperative neuromonitoring findings such as latency and amplitude values of the recurrent laryngeal nerves during thyroidectomy. To our knowledge this is the first study to report comparison of the electrophysiologic features of diabetic and non-diabetic patients.

Much remains unknown about the effects of sport concussion, and changes in markers of psychological and physiological stress over the recovery timeline.

Objective: To examine psychological (mood, stress, sleep quality, and symptoms) and physiological (heart rate variability and salivary cortisol) measures in concussed athletes over clinical recovery milestones.

Psychogenic non-epileptic seizures in the post-anesthesia recovery unit.

Braz J Anesthesiol

July 2017

Department of Anesthesiology, Mayo Clinic, Jacksonville, FL, United States.

Introduction: Psychogenic non-epileptic seizures (PNES or "pseudoseizures") remain an obscure topic in the peri-operative setting. They are sudden and time-limited motor and cognitive disturbances, which mimic epileptic seizures, but are psychogenically mediated. Pseudoseizures occur more frequently than epilepsy in the peri-operative setting.

Brief electrical stimulation after facial nerve transection and neurorrhaphy: a randomized prospective animal study.

J Otolaryngol Head Neck Surg

February 2016

Department of Surgery, Division of Otolaryngology-Head and Neck Surgery, University of Alberta, Edmonton, AB, Canada.

Background: Recent studies have examined the effects of brief electrical stimulation (BES) on nerve regeneration, with some suggesting that BES accelerates facial nerve recovery. However, the facial nerve outcome measurement in these studies has not been precise or accurate. The objective of this study is to assess the effect of BES on accelerating facial nerve functional recovery from a transection injury in the rat model.

Division of Otolaryngology,Department of Special Surgery,Faculty of Medicine, Jordan University of Science and Technology,Irbid,Jordan.

Objective: This literature review analysed facial nerve management strategies in jugular paraganglioma surgery and discusses the tumour resection rate and the facial nerve outcome associated with each technique.

Methods: A retrospective review of PubMed and Medline articles on the surgical treatments for jugular paraganglioma was performed. Tumour resection rates and post-operative facial nerve function after non-rerouting, short anterior rerouting and long anterior rerouting approaches were evaluated for each article.

Recurrent laryngeal nerve (RLN) injury in neonates, a complication of patent ductus arteriosus corrective surgery, leads to aspiration and swallowing complications. Severity of symptoms and prognosis for recovery are variable. We transected the RLN unilaterally in an infant mammalian animal model to characterize the degree and variability of dysphagia in a controlled experimental setting.

The purpose of this study was to evaluate cardiac autonomic modulation in university athletes during the post-acute to late phase (mean, 95 days ±63) of injury at rest and during physical exertion. We also sought to evaluate the effect of time since injury and number of injuries on heart rate variability (HRV). We hypothesized that physical exertion would reveal persisting modifications in HRV following a concussion.

Fluorescently labeled peptide increases identification of degenerated facial nerve branches during surgery and improves functional outcome.

PLoS One

January 2016

Division of Head and Neck Surgery, University of California San Diego, La Jolla, California, United States of America; Department of Pharmacology, University of California San Diego, La Jolla, California, United States of America; Moores Cancer Center, University of California San Diego, La Jolla, California, United States of America.

Nerve degeneration after transection injury decreases intraoperative visibility under white light (WL), complicating surgical repair. We show here that the use of fluorescently labeled nerve binding probe (F-NP41) can improve intraoperative visualization of chronically (up to 9 months) denervated nerves. In a mouse model for the repair of chronically denervated facial nerves, the intraoperative use of fluorescent labeling decreased time to nerve identification by 40% compared to surgeries performed under WL alone.

Guillain-Barré Syndrome (GBS) is a demyelinating polyneuropathy resulting in sensory, motor and autonomic symptoms. The severity of the disease can range from mild to severe but it is classically described as an ascending demyelinating process. Initially thought to be the sequelae of a bacterial or viral infection, the clinical symptoms of post-infective GBS can present up to 4 weeks after sentinel injury.
