Causes and time-course of vertigo in an ear, nose, and throat clinic

Abstract

The purpose of this study is to review etiologies and identify the time-course of vertigo presenting in an ear, nose, and throat clinic, and serve as a reference guide for other clinics. The study includes retrospective chart review in a tertiary care, university hospital. The patient data with reported ICD-10 codes as causes of vertigo between April 2005 and December 2007 were extracted from the database. At each visit, the main diagnosis as to etiology, characteristics of the vertigo, its time-course, and patient demographic data were recorded. Of 547 cases, 17 diagnoses were made in 73.9%. Diagnostic categories included peripheral vertigo 72.9%, central vertigo 0.8%, psychogenic cause 0.2%, and unknown 26.1%. Common causes of vertigo were benign paroxysmal positional vertigo (BPPV) 52.5%, Meniere's disease 14.6%, and sudden idiopathic hearing loss 2.9%. Less common diagnoses were benign paroxysmal vertigo of childhood 0.7%, labyrinthitis 0.7%, and vestibular schwannoma 0.3%. Rare conditions were delayed endolymphatic hydrops, Ramsey Hunt syndrome, otosyphilis, vestibular neuritis, temporal bone fracture, post-concussion syndrome, cerebellar infarction, epilepsy, cervical vertigo, Streptococcus suis meningitis, and psychogenic vertigo. Ninety-nine cases who reported remission of vertigo during the study period had median onset of the remission at 4 weeks. In the ear, nose, and throat clinic at Chiang Mai University, a tertiary university hospital, peripheral vestibular disorders were the main etiology of vertigo. The three most common causes were BPPV, Meniere's disease, and sudden idiopathic hearing loss. Half of the cases who returned for follow up had remitted symptoms within 4 weeks.

Predictive value of the neutrophil-to-lymphocyte ratio in patients with deep neck space infection secondary to acute bacterial tonsillitis

“…In recent years, several studies have reported that NLR may be used as marker of inflammation, both in cardiac and non-cardiac disorders [12][13][14][15][16][17][18].…”

“…Recently, a number of studies have reported that the neutrophilto-lymphocyte ratio (NLR) has potential as a marker of inflammation, both in cardiac and non-cardiac disorders [12][13][14][15][16][17][18]. Besides being a valuable biomarker for cardiac diseases, NLR is also a potential marker for inflammatory conditions caused by Objective: The aim of this study was to determine whether the neutrophil-to-lymphocyte ratio (NLR) can be used as a predictor for deep neck space infections (DNSIs) that occur as a complication of acute bacterial tonsillitis in the pediatric population.…”

Epidemiology of vestibular vertigo in a neuro-otology clinic population in Thailand

“…Only 0.8 per cent of the remaining cases were thought to have a central cause, and 26 per cent were 'unclassified'. 2 While these data suggest that vestibular migraine is not often seen in Thailand, the matter remains unresolved because the review's methodology may not have selected vestibular migraine cases. In Isaradisaikul and colleagues' review, the screening criterion for chart review was a hospital attendance coded with an International Classification of Diseases version 10 code pertaining to vertigo.…”

“…Previous work from Thailand found that the most common diagnoses were benign paroxysmal positional vertigo (BPPV) and Ménière's disease (K Y K Bangpoophamorn and S Sirompotong, unpublished data). [1][2][3] However, the majority of these data was reported prior to widespread awareness of the diagnosis of vestibular migraine. Subsequently, the international literature has indicated that, whenever studied, vestibular migraine and BPPV are the most prevalent causes of vertigo reported.…”

Characteristics of Patient with Benign Paroxysmal Positional Vertigo in Dr. Hasan Sadikin General Hospital Bandung from 2009‒2013

“…The BPPV is usually idiopathic and found among people aged 46-50 year old. 7 The method to diagnose BPPV is Dix-Halpike maneuver. It is used to induce nystagmus which is one of the characteristics of BPPV.…”
