Bidirectional connectivity alterations in schizophrenia: a multivariate, machine-learning approach.

Objective: It is well known that altered functional connectivity is a robust neuroimaging marker of schizophrenia. However, there is inconsistency in the direction of alterations, i.e.

Acute esophageal obstruction after ingestion of psyllium seed husk powder: A case report.

Background: Bezoar is a mass of hardened external material found in the gastrointestinal (GI) tract. It may form anywhere in the GI tract, but esophageal bezoar is rare because of the short esophageal transit time. Psyllium seed husk is an indigestible natural derivative that is widely used as an herbal laxative.

Impact of violence on the burnout status of paramedics in the emergency department: A multicenter survey study.

Background: Violence in emergency departments poses a threaten to both medical personnel and patients. We investigated the risk factors for high burnout status and the association between the impact of violence and burnout status of paramedics in emergency departments.

Methods: We included paramedics of emergency departments in Korea.

QRS complex characteristics and patient outcomes in out-of-hospital pulseless electrical activity cardiac arrest.

Background: Pulseless electrical activity (PEA) is increasingly observed in out-of-hospital cardiac arrest (OHCA), but outcomes are still poor. We aimed to assess the relationship between QRS characteristics and outcomes of patients with OHCA with initial PEA (OHCA-P).

Methods: This prospective observational study included patients aged at least 18 years who developed OHCA-P between 1 January 2016 and 31 December 2018, and were enrolled in the Daegu Emergency Medical Services registry, South Korea.

Laparoscopic Donor Hepatectomy for Adult Living Donor Liver Transplantation Recipients.

Even after 2 decades of experience in laparoscopic hepatectomy, data on purely laparoscopic approach for donor hepatectomy in adult living donor liver transplantation (LDLT) are limited. We report our initial experience of a purely laparoscopic approach for donor hepatectomy for adult recipients to explore its potential application in the management of donors. We did a retrospective data analysis of 54 consecutive patients operated on between May 2013 and February 2015.

The Effect of Bipolar Pulsed Radiofrequency Treatment on Chronic Lumbosacral Radicular Pain Refractory to Monopolar Pulsed Radiofrequency Treatment.

Background: Patients with lumbosacral radicular pain may complain of persisting pain after monopolar pulsed radiofrequency (PRF) treatment.

Objective: We evaluated the effect of bipolar PRF stimulation of the dorsal root ganglion (DRG) in patients with chronic lumbosacral radicular pain who were unresponsive to both monopolar PRF stimulation of the DRG and transforaminal epidural steroid injection (TFESI).

Study Design: This is a prospective observational study.

Comparison of Intraarticular Pulsed Radiofrequency and Intraarticular Corticosteroid Injection for Management of Cervical Facet Joint Pain.

Background: Disorders of the facet joints are some of the most common sources of chronic spinal pain. Facet joint pain is responsible for approximately 50% of patients with chronic neck pain. Pulsed radiofrequency (PRF) stimulation, after placing needle electrodes into the joint space, has been recently reported for the management of joint pain.

Epidural Dexamethasone Influences Postoperative Analgesia after Major Abdominal Surgery.

Background: Epidurally administered dexamethasone might reduce postoperative pain. However, the effect of epidural administration of dexamethasone on postoperative epidural analgesia in major abdominal surgery has been doubtful.

Objectives: To investigate the effects and optimal dose of epidural dexamethasone on pain after major abdominal surgery.

Changes in Neuroglial Activity in Multiple Spinal Segments after Caudal Epidural Pulsed Radiofrequency in a Rat Model of Lumbar Disc Herniation.

Background: Herniated lumbar discs can induce sciatica by mechanical compression and/or chemical irritation. It was recently reported that neuroglial cellular activity after pulsed radiofrequency (PRF) application to a single dorsal root ganglion (DRG) attenuated neuroglial activity at the corresponding spinal dorsal horn. Recently, caudal epidural PRF has been used to manage neuropathic pain, but evidence of molecular changes after the administration of caudal epidural PRF to attenuate neuropathic pain is lacking, and it has not been determined whether caudal epidural PRF affects neuroglial activity at different spinal levels.

Two-Year Outcome of Percutaneous Bipolar Radiofrequency Neurotomy of Sacral Nerves S2 and S3 in Spinal Cord Injured Patients with Neurogenic Detrusor Overactivity: A Randomized Controlled Feasibility Study.

Background: Little research has been expended on the use of bipolar radiofrequency (RF) lesioning of sacral nerves in spinal cord injured (SCI) patients with neurogenic detrusor overactivity (NDO), and no study has been undertaken to demonstrate its long-term effect.

Objective: To investigated the effect of bipolar RF ablation of the second and third sacral nerves over 2 years in SCI patients with NDO.

Study Design: A prospective, randomized controlled feasibility study.
