Vertigo emergency

UNLABELLED: The chief complaint of vertiginous symptoms can be daunting, and the differential is quite long. Approximately 15% of patients presenting to the emergency department (ED) with dizziness have a dangerous underlying cause.1 We present a case of a 40-year-old female with a sudden onset of what she describes as vertigo, in the setting of intermittent diplopia. The patient was found to have a left medial rectus palsy consistent with a left internuclear ophthalmoplegia. Internuclear ophthalmoplegia (INO) is an abnormal gaze that is characterized by the weakness or inability to adduct the affected eye...

INTRODUCTION: Dizziness is a common symptom with diverse causes, including ear-nose-throat, internal, neurological, or psychiatric origins. While for most parts treatable in nonemergency settings, it can also signal time-critical conditions, like an unnoticed stroke, requiring prompt diagnosis and treatment to prevent lasting harm or death. The aim of this study was to evaluate the validity of the Manchester Triage System in classifying patients presenting with dizziness based on final diagnoses and patient outcomes, as no specific flow chart exists for this symptom in the MTS...

INTRODUCTION: Trigeminal neuralgia is a rare condition characterised by paroxysms of intense pain in the distribution of the trigeminal nerve. This condition significantly diminishes the patient's quality of life, and the side effects from chronic use of medications for symptomatic relief further exacerbate their distress. CASE DESCRIPTION: The case report discusses a patient diagnosed with Trigeminal Neuralgia who commenced carbamazepine treatment. The report tracks the disease's progression, medication adjustments, and the eventual emergence of vertigo due to long-term carbamazepine use...

BACKGROUND Superior semicircular canal dehiscence is an inner-ear pathology which presents with vertigo, disequilibrium, and hearing loss. Although the exact etiology of superior semicircular canal dehiscence is unknown, it is thought that an increase in middle-ear pressure disrupts a thin overlying temporal bone. Superior semicircular canal dehiscence is frequently seen in association with dehiscence of the tegmen tympani, which overlies the middle ear. Here, we present a case report of a 52-year-old Puerto Rican man with vertigo, dizziness, vomiting, and mild hearing loss associated with superior semicircular canal and tegmen tympani dehiscence after performing improper scuba diving techniques...

INTRODUCTION: The objective of this study was to assess the prevalence of falls, fear of falling (FOF), complications arising from falls, and identify possible sociodemographic and health-related factors associated with these outcomes among older adults. METHODS: This cross-sectional study was based on the first wave of the Ardakan Cohort Study on Aging (ACSA), which includes participants over 50 years of age residing in Ardakan, Iran. Fall history, number of fall events, FOF, hospitalizations, and fractures in the past 12 months were assessed through a face-to-face interview...

BACKGROUND: In previous studies, it was shown that ischemia-modified albumin (IMA) is an early marker of ischemia and different pathologies. However, IMA level change is unknown in patients with peripheral vertigo. It is also known that serum albumin levels can change in some patients with peripheral vertigo and that changes in serum albumin levels affect IMA levels. AIM: In this study, we aimed to assess IMA, albumin-adjusted IMA, and albumin levels in patients with peripheral vertigo by comparing a control group...

BACKGROUND: Vertigo and dizziness are frequent presenting symptoms in the emergency department and in outpatient centers. While the majority of dizzy patients are evaluated by primary care physicians, specialists are often involved in the diagnostic workup. We aimed to gain more insights into the role of specialists in the care of dizzy patients. MATERIALS AND METHODS: Board-certified neurologists and ear-nose-throat (ENT) physicians working in Switzerland were invited to participate in an online survey...

Protection and restoration of the CaCO3 depositing alkaline fens require an in-depth understanding of these unique and declining ecosystems. The present study investigates the development of the formerly heavy tufa depositing alkaline fen in East-Central Europe after CaCO3 precipitation markedly declined ca. 5400 cal yr BP. By combining palaeoecological and monitoring data, we aim to identify the limiting factors for tufa deposition and to recognise the vegetation and mollusc response to the change...

OBJECTIVE: Patients with dizziness commonly present to Emergency Departments (ED) and 6% of these patients will be diagnosed with acute stroke. The TriAGe+ score comprises of eight clinical parameters and stratifies patients into four risk groups. The Japanese authors reported that the tool performed well, so our aim was to validate this diagnostic tool in our ED in Hong Kong. MATERIALS AND METHODS: A single-center retrospective observational study was conducted in the ED of our university hospital in Hong Kong...

This work utilises the strength of state space based dynamic modelling and the ability of machine learning based segmentation of SRM standard descriptors to reach superior diagnostic capabilities. Dynamic modelling ensured vHIT input-output characteristics generated SRM standard descriptors, which were consequently used in formation of ML classification models.The best ML model was Linear SVM when built on left and right sided data with the SRM standard descriptors: rise time, settling time, settling minimum, settling maximum, overshoot and undershoot...

BACKGROUND: Wallenberg syndrome, also known as a lateral medullary syndrome, is a rare neurological condition caused by an infarction in the brainstem's lateral medulla. There are subtypes of Wallenberg syndrome with distinctive and atypical symptoms, such as Opalski syndrome. CASE PRESENTATION: A 41-year-old hypertensive male arrived at the emergency department with abrupt onset of right-sided bodily weakness, vertigo, facial numbness, dysphagia, hoarseness of voice, and double vision...

PURPOSE OF REVIEW: A decade has passed since vestibular migraine (VM) was formally established as a clinical entity. During this time, VM has emerged amongst the most common cause of episodic vertigo. Like all forms of migraine, VM symptoms are most prominent during individual attacks, however many patients may also develop persistent symptoms that are less prominent and can still interfere with daily activities. RECENT FINDINGS: Vestibular inputs are strongly multimodal, and because of extensive convergence with other sensory information, they do not result in a distinct conscious sensation...

OBJECTIVES: Benign paroxysmal positional vertigo (BPPV) is a condition in which a patient gets severe vertigo on moving his head from one position to another. This study aims at comparing the traditional maneuver-Epley repositioning maneuver (ERM) and the newly emerged maneuver-Gans Repositioning maneuver (GRM). DESIGN: A randomized controlled trial. SETTINGS: Tertiary care teaching University Hospital. PARTICIPANTS: Posterior canal BPPV...

Pseudotumoral hemicerebellitis is a rare presentation of acute cerebellitis, which involves the inflammation of a single cerebellar hemisphere and most commonly affects children. It mimics a tumor on imaging, hence given the name. In this report, we present a case of pseudotumoral hemicerebellitis in a 30-year-old male who presented to the emergency room (ER) with complaints of vertigo, vomiting, and a headache.

BACKGROUND: Dizziness is a common reason for people to seek medical care. Acute vestibular syndrome (AVS) is a specific type of dizziness, which can include severe vertigo, nausea and vomiting, nystagmus, or unsteadiness. Acute vestibular syndrome can be due to peripheral or central causes. It is important to determine the cause, as the intervention and outcomes differ if it is from a peripheral or central cause. Clinicians can assess for the cause using risk factors, patient history, examination findings, or advanced imaging, such as a magnetic resonance imaging (MRI)...

A woman in her 70s presented to primary care clinic complaining of acute onset dizziness for 1 day that was initially diagnosed as vestibular neuritis and treated with steroids. The next day, she presented to the emergency department with worsening symptoms. Imaging revealed no intracranial process; however, non-contrast CT imaging revealed a soft-tissue mass in the posterior ethmoid sinus. The vertigo completely resolved before an otolaryngologist surgically removed the nasal mass, which actually originated from the right cribriform plate and extended to the anterior middle turbinate head...

OBJECTIVE: In this Italian population-based study, we aimed to evaluate the neurological complications after the first and/or second dose of COVID-19 vaccines and factors potentially associated with these adverse effects. METHODS: Our study included adults aged 18 years and older who received two vaccine doses in the vaccination hub of Novegro (Milan, Lombardy) between 7 and 16 July 2021. The NEURO-COVAX questionnaire was able to capture the neurological events, onset and duration...

Filamin A is a protein essential for cytoskeleton production, encoded by the X-lined dominantly inherited FLNA gene. A deficiency in filamin A can lead to cardiac valvular dysplasia and periventricular nodular heterotopia in the brain. Notably, periventricular heterotopia Type 1 has associations with cardiovascular abnormalities. We report the case of a 40-year-old woman who visited the emergency department due to shortness of breath, intermittent desaturation, and vertigo. Initial diagnostic procedures unexpectedly identified a sinus of Valsalva aneurysm on a computed tomography scan of the thorax and MRI brain revealed subependymal nodules in the lateral ventricles, suggesting an FLNA mutation...

BACKGROUND: There are evidence-based bedside tests for diagnosing acute vertigo, but no evidence-based strategies to support clinicians in implementing them. The purpose of this study was to design an implementation strategy for treating acute vertigo by examining current facilitators and barriers to using these tests in the ED using the principles of implementation science. METHODS: A survey was developed using the Theoretical Domains Framework and Consolidated Framework for Implementation Research to examine barriers and facilitators for using HINTS+ (head impulse, nystagmus, test of skew, plus hearing) and Dix-Hallpike tests...

OBJECTIVE: Idiopathic sudden sensorineural hearing loss (ISSNHL), as an otologic emergency, is commonly encountered and its prevalence has been climbing every year recently. To our knowledge, the prognosis of middle-aged and elderly patients is worse than that of young patients. Previous researches mainly focused on the adult population, which was considered as prognostic models who performed hearing recovery in ISSNHL. However, few studies regarding the middle-aged and elderly population who are regarded as prognostic models have been reported...
