Introduction: Cervical spine abnormalities can affect the ear vessels and or nerves with different mechanisms. Ear dysfunctions following cervical spine injuries can be manifested as hearing loss, vertigo, or tinnitus. Usually, cervical spine injuries can cause pain and Range of Motion (ROM) limitation. The major objective of this study was to determine which cervical ROM limitation was accompanied with higher level of hearing loss. Methods: In this cross-sectional study, 42 volunteers (20 women and 22 men) with cervical spine injury and pain participated after giving their informed consent...

INTRODUCTION: Benign paroxysmal positional vertigo (BPPV), involving the semicircular canals, is one of the most common diseases of the inner ear. The video head impulse test (vHIT) is a new test that examines the function of the canals. This study aimed to investigate the vestibulo-ocular reflex (VOR) gain, gain asymmetry and saccades after stimulating all six canals in patients definitively diagnosed with posterior semicircular canal BPPV (PSC-BPPV). MATERIALS AND METHODS: Twenty-nine unilateral PSC-BPPV patients with normal oculographic and caloric results were enrolled in this study...

BACKGROUND: Cerebellar infarction is an uncommon but serious cause of isolated acute vestibular symptoms, particularly in young, healthy individuals, and can easily be overlooked. We present two cases of cerebellar infarction in U.S. Air Force pilots, one of which occurred during flight. CASE REPORTS: A 41-yr-old man developed acute vertigo, disequilibrium, nausea, and headache, with progressive slow symptomatic improvement, and presented to medical attention 4 d after symptom onset...

Functional vertigo and dizziness (VD) symptoms are highly prevalent and usually accompanied by a strong impairment of quality in everyday and working life. The complaints are often associated with various psychiatric disorders, particularly phobic and other anxiety disorders, depressive or somatoform disorders. Despite this clinical relevance of VD symptoms, studies towards psychotherapeutic treatment options for patients with functional VD are still rare. Thus, the present study outlines a manual for outpatient group therapy for patients with functional VD symptoms...

BACKGROUND: For virtual reality laparosopic simulation we developed a new, highly immersive simulation mode. The goal of the current pilot study was to investigate if kinetosis or other negative vegetative side effects can be caused by a total virtual training set-up (TVRL). METHODS: In this study 20 participants with varying degrees of expertise in laparoscopy performed 3 tasks (i.e. ring exchange, fine dissection and cholecystectomy) in regular (VRL) and immersive mode (TVRL) with a head-mounted display (HMD) on a laparoscopic simulator...

Rehabilitation for vestibular disease is a safe method to partially alleviate symptoms of vertigo. It was hypothesized that principles of military aviation vestibular desensitization procedures that have a success rate of more than 80% can be extrapolated to chronic vestibular disease as well.The virtual reality motion base computer-assisted rehabilitation environment was used as treatment modality in 17 patients. They were exposed to sinusoidal vertical passive whole body motion in increasing intensity for a maximum of 12 sessions...

AIM: The prevalence of benign paroxysmal positional vertigo (BPPV) is higher in people with type 2 diabetes (DM). The impact of DM on mobility, balance, and management of BPPV is unknown. This prospective study compared symptom severity, mobility and balance before and after the canalith repositioning maneuver (CRM) in people with posterior canal BPPV canalithiasis, with and without DM. METHODS: Fifty participants, BPPV (n=34) and BPPV+DM (n=16) were examined for symptom severity (dizziness handicap inventory, DHI), mobility (functional gait assessment, FGA), and postural sway (using an accelerometer in five conditions) before and after the CRM...

Objective: To evaluate the correlation between type Ⅰ allergic reaction and pathogenesis of Meniere's disease. Methods: A total of 35 (10 male vs. 25 female) patients aged between 21-66 years diagnosed with Meniere's disease were recruited to this study, mean age of them was (47.3±13.6) years. The control group consisted of 15 inpatients (5 male vs. 10 female) with pharyngolaryngeal diseases but without otologic and rhinologic abnormity, mean age was 45.4±12.8 years. Allergic prevalence, serous total immunoglobulin E( tIgE ) levels, serous specific immunoglobulin E( sIgE ) levels and subtypes of T lymphocytes were measured and compared in patients with Meniere's disease and the control group...

UNLABELLED: Meniere's disease, a common inner ear condition, has an incidence of 15-50 per 100,000. Because mental/physical stress and subsequent increase in the stress hormone vasopressin supposedly trigger Meniere's disease, we set a pilot study to seek new therapeutic interventions, namely management of vasopressin secretion, to treat this disease. We enrolled 297 definite Meniere's patients from 2010 to 2012 in a randomized-controlled and open-label trial, assigning Group-I (control) traditional oral medication, Group-II abundant water intake, Group-III tympanic ventilation tubes and Group-IV sleeping in darkness...

BACKGROUND: Presented is a rare case of transient unilateral facial nerve paralysis occurring in a pilot while on initial ascent in an F-16CM. This pathology is sporadically observed in the diving community, but rarely described in military or civil aviation. This case was particularly unusual in its promptness of onset, rapid recovery, and its association with vertigo. CASE REPORT: This case report describes a previously healthy 26-yr-old F-16 pilot who experienced ear block and subsequent unilateral facial paralysis while on initial ascent...

BACKGROUND: Stroke is a decidedly devastating event for any patient, but particularly for a military aviator in a single-seat aircraft. Incidence of acute ischemic infarct in men ages 25 to 29 ranges from 3.4 to 5.6/100,000. The neurological sequelae of stroke can have a lasting and profound impact on an aviator's career. Literature review revealed a relatively small number of cases where stroke was attributable to cervical manipulation. CASE REPORT: A 29-yr-old male jet pilot with a 2-wk history of cervicalgia following a mountain bike ride performed self-manipulation of his neck at home following a visit to a chiropractor...

We lately reported the cases of patients complaining positional vertigo whose nystagmic pattern was that of a peripheral torsional vertical positional down beating nystagmus originating from a lithiasis of the non-ampullary arm of the posterior semicircular canal (PSC). We considered this particular pathological picture the apogeotropic variant of PSC benign paroxysmal positional vertigo (BPPV). Since the description of the pilot cases we observed more than 150 patients showing the same clinical sign and course of symptoms...

BACKGROUND: Dizziness and vertigo account for roughly 4% of chief symptoms in the emergency department (ED). Pharmacological therapy is often applied for these symptoms, such as vestibular suppressants, anti-emetics and benzodiazepines. However, every medication is accompanied with unavoidable side-effects. There are several research articles providing evidence of acupuncture treating dizziness and vertigo but few studies of acupuncture as an emergent intervention in ED. We performed a pilot cohort study to evaluate the efficacy and safety of acupuncture in treating patients with dizziness and vertigo in ED...

Vertigo is generally due to a benign disorder, but it is the most common symptom associated with misdiagnosis of stroke. In this pilot study, we preliminarily assessed the diagnostic performance of a structured bedside algorithm to differentiate central from non-central acute vertigo (AV). Adult patients presenting to a single Emergency Department with vertigo were evaluated with STANDING (SponTAneous Nystagmus, Direction, head Impulse test, standiNG) by one of five trained emergency physicians or evaluated ordinarily by the rest of the medical staff (control group)...

The aim of this study was to investigate the vertebral artery (VA) morphology of enlistment-age male student pilots with ultrasound to provide a basis for early diagnosis of potentially asymptomatic cervical vertigo. Ultrasound results of the origin position, diameter and hemodynamics of the VA in 935 cases of student pilots with a mean age of 18.0 y were analyzed. The inner diameters of both sides of the VA differ: the left is larger than the right statistically (p < 0.001). Moreover, the peak systolic velocity of the left VA is significantly greater than that of the right (p < 0...

In recent years research explored different acupuncture stimulation techniques but interest has focused primarily on somatic acupuncture and on a limited number of acupoints. As regards ear Acupuncture (EA) there is still some criticism about the clinical specificity of auricular points/areas representing organs or structures of the body. The aim of this study was to verify through (Functional magnetic resonance imaging) fMRI the hypothesis of EA point specificity using two auricular points having different topographical locations and clinical significance...
