Evaluation of Vestibular Functions in a Case of Vestibular Migraine With Successful Treatment With Erenumab.

This is the first report of vestibular examinations before and after the successful treatment of vestibular migraine (VM), a common cause of recurrent vertigo, with calcitonin gene-related peptide (CGRP) receptor inhibitor. We evaluated a 42-year-old female with VM and concomitant probable Meniere's disease, whose headache and dizziness have improved promptly with the administration of erenumab, a CGRP receptor inhibitor. The sensorineural hearing loss in pure-tone audiometry, dysfunctions shown in vestibular examinations (cervical and ocular vestibular evoked myogenic potentials), and mild endolymphatic hydrops shown in gadolinium-enhanced inner ear magnetic resonance imaging, all in the right ear, revealed no change compared with those observed before treatment.

Does repeat laparoscopic hepatectomy without extracorporeal Pringle manoeuvre worsen treatment outcomes?

Introduction: The Pringle manoeuvre is used in most hospitals to counteract intraoperative haemorrhage in laparoscopic hepatectomy by occluding the flow of blood to the liver. However, in laparoscopic repeat hepatectomy (LRH), outcomes of previous surgery and the influence of other factors frequently make it difficult to occlude the inflow of blood.

Aim: To discuss the value of inflow occlusion during LRH and provide tips for its performance.

Neuron-specific enolase level is a useful biomarker for distinguishing amyotrophic lateral sclerosis from cervical spondylotic myelopathy.

The current study aimed to evaluate whether cerebrospinal fluid (CSF) neuron-specific enolase (NSE) levels are elevated in amyotrophic lateral sclerosis (ALS) and are effective in distinguishing ALS from cervical spondylotic myelopathy (CSM). We retrospectively evaluated 45 patients with ALS, 23 with CSM, 28 controls, and 10 with Parkinson's disease (PD) who underwent analysis of CSF NSE levels. The control group comprised patients aged above 45 years who underwent lumbar puncture because of suspected neurological disorders that were ruled out after extensive investigations.

An electrophysiological classification associated with Guillain-Barré syndrome outcomes.

Guillain-Barré syndrome (GBS) is an acute, post-infectious, inflammatory, autoimmune peripheral neuropathy with a highly diverse clinical course and outcome. We classified GBS on the basis of patients' first nerve conduction and validated this system to be associated with outcome on the basis of electrophysiological characteristics during the acute phase of GBS. We retrospectively evaluated 40 GBS patients who underwent their first electrophysiological study within 14 days of onset and classified GBS into four patterns: (1) acute inflammatory demyelinating polyneuropathy (AIDP) pattern with sensory nerve conduction abnormalities (motor-sensory AIDP: MS-AIDP), (2) AIDP pattern without sensory nerve conduction abnormalities (motor AIDP: M-AIDP), (3) acute motor axonal neuropathy (AMAN) pattern, and (4) minor abnormalities pattern.
