Abstract
BACKGROUND Benign paroxysmal positional vertigo (BPPV) is a debilitating condition that has been significantly described in adults. Recent data points out that BPPV occurs in children as well. Canalith repositioning manoeuvre (CRM) has shown promising results amongst adult patients with BPPV. OBJECTIVE We reviewed the literature to determine the outcome of CRM in children and adolescents with BPPV. METHODS A literature search was conducted over 1 month (March 2022). The primary outcome was defined as the resolution of positional nystagmus and symptoms, and secondary outcomes were determined by the presence of recurrence and the number of attempts of CRM. RESULTS Ten articles were selected based on our objective and selection criteria. A total of 242 patients were included, with a mean of 10.9 years. BPPV was diagnosed based on history and positional nystagmus in all patients (100%). CRM was performed in 97.9% of patients, whereby 80.5% recovered following a single attempt of CRM. Recurrence of symptoms was identified in 10% of patients with no reported major complications. CONCLUSION CRM has demonstrated promising results in children and adolescents. The quality of evidence is limited until a better-quality study involving randomised controlled studies with a larger sample size is completed.

Abstract
The aim of this study was to assess the prevalence and analyze clinical parameters of benign positional paroxysmal vertigo (BPPV) in a pediatric age. A cohort of 423 children under the age of 15 (median age 11. interquartile range 9-13) was submitted to vestibular assessment for balance disorders. Dix-Hallpike and Roll-Supine tests were performed to look for positioning nystagmus using video-infrared goggles. BPPV was found in 43 of 423 children evaluated for balance disorders (10.2%). There were 28 females (65.1%) and 15 (34.9%) males. The posterior canal was involved in 79% of cases and the horizontal canal in 21% of cases. No apogeotropic bilateral or anterior canal form were seen. Thus, BPPV is not an infrequent type of vertigo in children and must be evaluated as soon as possible in order to plan the most appropriate maneuver and restore daily activities as soon as possible, avoiding anxiety and fear.

Abstract
Objective The aim of the study was to determine the features and differential diagnosis of childhood dizziness and find out the prevalence of neurological diseases in children who were referred to the pediatric neurology outpatient clinic. A secondary aim was to evaluate the outcome of dizziness after 12 months. Material and Methods The records of children with a complaint of dizziness that were referred to the pediatric neurology outpatient clinic were retrospectively reviewed, and detailed medical and family history, clinical characteristics, laboratory investigations including vitamin B12 levels, and neuroimaging tests were analyzed. Patients were grouped as neurological disorders and non-neurological disorders. Neurological disorders included vestibular migraine, benign paroxysmal vertigo, and epilepsy, and non-neurological disorders contained the remaining disorders. Results The study consisted of 60 children (36 females, 24 males) with a mean age of 11.7±4.1 years. The most common diagnoses were vestibular migraine (21.7%) and orthostatic hypotension (20%). We found that the incidence of neurological diseases was 40% (vestibular migraine, 21.7%; epilepsy, 10%; benign paroxysmal vertigo, 8.3%). When we compared the neurological disorders with non-neurological disorders, there was a significant difference in terms of age at onset and duration of attacks (p=0.001 for both), whereas no significant difference was detected in terms of gender, frequency of attacks, and vitamin B12 levels. We detected ongoing symptoms in 10% of the patients who were diagnosed with vestibular migraine and psychogenic dizziness. Conclusion Both non-neurological and neurological diseases are common in etiology of children with dizziness.

Abstract
OBJECTIVE The clinical features and incidence of benign paroxysmal positional vertigo (BPPV) are not well known in pediatric populations. The aim of this study was to describe the clinical characteristics of pediatric BPPV and to estimate the frequency of pediatric BPPV in the general population. METHODS We retrospectively reviewed the medical records of 20 children (6-14 years old) diagnosed with BPPV between 2007 and 2017. The age/sex distribution of BPPV for all ages at our hospital and in the Korean Health Insurance Review and Assessment Service-National Patient Sample (HIRA-NPS) database were compared. The annual incidence and proportion of children with BPPV were calculated. RESULTS BPPV occurred 1.86 times more frequently in girls than in boys. Nine children (45%) had associated comorbidities, such as inner ear disorders and recent head trauma. The posterior and lateral semicircular canals were most commonly involved (n = 9 for each), and recurrence was observed in two patients (10%). Children younger than 15 years accounted for approximately 1% of all BPPV cases. The annual incidence of BPPV was 171.5/100,000 for all ages and 9.5/100,000 in the pediatric population. CONCLUSIONS Our findings suggest that pediatric BPPV is a relatively uncommon cause of vertigo in children and that the rates of related illness and recurrence are high.

Clinical significance of spontaneous nystagmus in pediatric patients. Int J Pediatr Otorhinolaryngol 2018; 111:103-107.

Abstract
OBJECTIVE To analyze spontaneous nystagmus recorded in pediatric patients and determine its diagnostic value. MATERIALS AND METHODS Retrospective review of 86 patients (mean age = 13.9 ± 4.7 years) with definitive spontaneous nystagmus recorded by videonystagmography (VNG). Spontaneous nystagmus was categorized and analyzed based on its characteristics. Correlations between spontaneous nystagmus and established clinical diagnoses were explored. RESULTS Among the patients seen in a period of three years at our pediatric vestibular clinic, 15.4% (86 out of 560) were found to have spontaneous nystagmus and half of them had horizontal nystagmus with a fixed-direction. The majority of cases with spontaneous nystagmus (77%, 66/86) were present without fixation only, while the presence of spontaneous nystagmus with and without fixation was found in 16 patients (19%). Most patients with spontaneous nystagmus without fixation only (68%) were diagnosed with a peripheral vestibular disorder (e.g., vestibular neuritis) or vestibular migraine. In contrast, vertical nystagmus was found in 15 patients, most of whom had central vestibular disorders. Other rare forms of nystagmus or abnormal eye movements, such as pendular nystagmus, ocular oscillation or flutter were recorded in only four patients. CONCLUSIONS Spontaneous nystagmus in children and young adults with possible vestibular impairments may vary in clinical presentation. Identification of its characteristics may help to make an accurate clinical diagnosis. While spontaneous nystagmus associated with peripheral vestibular disorders can be readily recognized, spontaneous nystagmus in pediatric patients with vestibular migraine appears to be more complex and variable in form.

Abstract
ObjectiveTo define a disorder characterized by recurrent spontaneous vertigo (RSV) of unknown etiology and interictal headshaking nystagmus (HSN).MethodsWe characterized HSN in 35 patients with RSV-HSN compared to that recorded in randomly selected patients with compensated vestibular neuritis (VN), vestibular migraine (VM), and Ménière disease (MD).ResultsThe estimated time constant (TC) of the primary phase of HSN was 12 seconds (95% confidence interval [CI] 12–13) in patients with RSV-HSN, which was larger than those in patients with VN (5 seconds, 95% CI 4–5), VM (5 seconds, 95% CI 5–6), or MD (6 seconds, 95% CI 5–6). TCs of the horizontal vestibulo-ocular reflex were also larger during the rotatory chair test in patients with RSV-HSN. Among the 35 patients with RSV-HSN, 7 showed vigorous long-lasting HSN with a peak slow-phase velocity >50.0°/s. In 5 patients (5 of 7, 71%) with vigorous HSN, HSN could have been induced even with headshaking for only 2 to 5 seconds. Long-term prognosis was favorable, with a resolution or improvement of the symptoms in more than half of the patients during the median follow-up of 12 (range 2–58) years from symptom onset. None developed VM, MD, or cerebellar dysfunction during the follow-up.ConclusionThe clinical features and characteristics of HSN in our patients indicate a hyperactive and asymmetric velocity-storage mechanism that gives rise to intermittent attacks of spontaneous vertigo probably when marginal compensation of underlying pathology is disrupted by endogenous or exogenous factors.

Abstract
Sudden balance disorders with violent vegetative symptoms (nausea and vomiting) pose a diagnostic and therapeutic problem. In children vertigo/dizziness with symptoms of vestibular dysfunction is rare, but as vascular etiology is unlikely in children such symptoms arouse concern. This article presents two cases of this type of vertigo. The patients were two boys (6 and 9 years old). They came down with similar symptoms: sudden dizziness, disabled walking, nausea and vomiting, spontaneous nystagmus, and a positive Romberg test. The onset of the balance disorder was preceded by respiratory infection: common cold with symptoms of inflammation of the mucous membrane in the nose and throat. Laboratory tests revealed increased levels of C-reactive protein only in the older boy. Neuroinfection and a displacement process were ruled out. Videonystagmography revealed vestibular dysfunction and vestibular neuronitis on the left side.

Abstract
Aim The aim of this article is to explore the progression of neurological, neuro-otological and cochlear features in benign paroxysmal vertigo (BPV) in children over time and its relation with migraine, neuro-otological and cochlear disorders in adulthood. Methods From January 2002 to December 2002, 15 children with BPV were prospectively recruited and then evaluated during a 10-year observational follow-up. All patients underwent detailed neurological, neuro-otological and cochlear examinations during interictal phases. Six children were also studied during ictal periods. Results At first assessment, four children reported migraine with aura (MwA) and six children reported migraine without aura (MwoA). Neuro-otological examinations were abnormal in two of 15 children. Cochlear examinations were normal in all patients. During the 10-year follow-up, recurrent vestibular symptoms and/or MwA and/or MwoA have been observed in the children. Neuro-otological examinations were abnormal in three of 15 individuals during the interictal period, and abnormal in four out of six patients who were studied during the ictal period. Two patients developed cochlear signs and/or symptoms. Conclusions During the 10-year follow-up, a phenotype variability in BPV patients has been observed. Specifically, de novo cochlear signs and/or symptoms developed in children with BPV, suggesting that cochlear symptoms should be properly investigated in these patients over time.

Abstract
Evaluation of acute ataxia in a child poses a dilemma for the clinician in determining the extent and timing of initial screening tests. This article reviews the evidence concerning the diagnostic yield of commonly ordered tests in evaluating the child with acute ataxia. The literature revealed the following frequencies of laboratory screening abnormalities in children with acute ataxia: CT (∼2.5%), MRI (∼5%), lumbar puncture (43%), EEG (42%), and toxicology (49%). In most studies, abnormalities detected by these screening tests were nondiagnostic. There are insufficient data to assess yields of testing for autoimmune disorders or inborn errors of metabolism. A toxicology screen should be considered in all children presenting with acute ataxia. Neuroimaging should be considered in all children with new onset ataxia. Cerebrospinal fluid analysis has limited diagnostic specificity unless clinically indicated. Studies to examine neurophysiology testing did have sufficient evidence to support their use. There is insufficient evidence to establish a role for autoantibody testing or for routine screening for inborn error of metabolism in children presenting with acute ataxia. Finally, in a child presenting with ataxia and opsoclonus myoclonus, urine catecholamine testing for occult neuroblastoma is recommended. Nuclear scan may be considered, however, there is insufficient evidence for additional body imaging.

Abstract
Objectives. To describe the characteristics and outcome of vertigo in a pediatric population. Patients. All children and adolescents presenting with vertigo to a tertiary otoneurology clinic between the years 2003–2010 were included in the study. Results. Thirty-seven patients with a mean age of 14 years were evaluated. The most common etiology was migraine-associated vertigo (MAV) followed by acute labyrinthitis/neuritis and psychogenic dizziness. Ten patients (27%) had pathological findings on the otoneurological examination. Abnormal findings were documented in sixteen of the twenty-three (70%) completed electronystagmography evaluations. Twenty patients (54%) were referred to treatment by other disciplines than otology/otoneurology. A follow-up questionnaire was filled by twenty six (70%) of the study participants. While all patients diagnosed with MAV had continuous symptoms, most other patients had complete resolution. Conclusions. Various etiologies of vertigo may present with similar symptoms and signs in the pediatric patient. Yet, variable clinical courses should be anticipated, depending on the specific etiology. This is the reason why treatment and follow up should be specifically tailored for each case according to the diagnosis. Close collaboration with other medical disciplines is often required to reach the correct diagnosis and treatment while avoiding unnecessary laboratory examinations.

Abstract
BACKGROUND AND AIMS Dizziness, impaired balance and fear of falling are common complaints in the elderly. We evaluated the association of vestibular symptoms with vestibular findings in the elderly by posturography and video-oculography (VOG). METHODS We studied 38 oldest old subjects (≥ 85 yrs, mean age 89) living in a residential home. Vestibular symptoms were taken with a structured questionnaire, the Mini Mental State Examination (MMSE) was scored and any falls were recorded over a period of 12 months. Posturography was measured with a force platform and eye movements were measured by video-oculography. RESULTS In the majority of the elderly, vestibular abnormalities were found, such as reduced vestibulo-ocular reflex gain 6/38, spontaneous nystagmus 5/38, gaze deviation nystagmus 5/38, head shaking nystagmus 9/38, pathologic head thrust test 10/38, and positional nystagmus 17/38. Posturography demonstrated two major findings: the body support area was limited and the use of vision for postural control was reduced. In principal component analysis of the vertigo, four major factors described elements of failure in the vestibular and other systems important to maintenance of balance: episodic vertigo, postural instability, multisystem failure (frail) and presyncopal imbalance. These four factors were associated in different degrees to vestibular abnormalities and falls. During the follow-up period, in 19 elderly (19/38), one or more falls were recorded. CONCLUSIONS Progressive loss of balance in the aged, or "presbyequilibrium," is a complex and incompletely understood process involving vestibular, oculomotor, visual acuity, proprioception, motor, organ system and metabolic weaknesses and disorders. These factors provide a potential basis for streamlining diagnostic evaluations and aiding in planning for effective therapy. In oldest old, these problems are magnified, increasing the need for additional expertise in their care, which may be met by training specialized healthcare staff.

Abstract
OBJECTIVE AND IMPORTANCE Benign paroxysmal positional vertigo (BPPV) is an uncommon complication that can develop after cochlear implantation. This condition has been documented in adults as a complication of cochlear implant surgery. However, there is no reported literature on BPPV in children who have undergone cochlear implant surgery. CLINICAL PRESENTATION A 13-year-old girl underwent the insertion of a cochlear implant and developed BPPV as a result of visiting fairground rides approximately 2 years after surgery. INTERVENTION We performed a right Epley's maneuver. She was advised to do Brandt-Daroff exercises for 6 weeks. She became symptom free within a few weeks of doing vestibular rehabilitation exercises. Nevertheless, she had been compliant with vestibular rehabilitation for 6 weeks. CONCLUSION The vibration injury to the labyrinth caused during the various rides could be analogous to the mechanism of trauma to the labyrinth as occurs during head injury. The other possibility could be dislodgement of the otoconia from the already vulnerable utricle that has been subject to cochlear implantation. It is presumed that the vulnerability of the labyrinth following the cochlear implantation happened as the child suffered from dizziness in the immediate post-operative period. However, a chance association between the insertion of the cochlear implant and the development of the symptoms of BPPV in this patient cannot be ruled out.

Abstract
OBJECTIVE The purpose of this study was to evaluate the presence and eventually to study the features of spontaneous nystagmus (Ny) in our patients with diagnosis of benign paroxysmal positional vertigo (BPPV). PATIENTS AND METHODS We retrospectively reviewed the clinical records of patients who presented with vertigo spells and were managed at our tertiary care referral center. Patients with only idiopathic BPPV presenting with typical vertigo spells and positioning Ny characteristic of the disease were included in this study. To investigate the positioning Ny, we studied the patients in the sitting position, during the head shaking test, and during the Dix-Hallpike test and the McClure-Pagnini test (Ny provoked by rotation of the head in a supine patient). Ny responses in all patients were observed using infrared videoscopy. RESULTS We managed 412 patients affected by BPPV. Of the 412 patients, 292 (70.87%) were diagnosed to be having posterior canal-BPPV and 110 (26.99%) patients had horizontal canal-BPPV (HC-BPPV). The remaining 10 patients (2.44%) were identified to have anterior canal-BPPV. Spontaneous Ny in sitting position was observed, by infrared videoscopy, only in the patients affected by HC-BPPV. CONCLUSION Spontaneous Ny in BPPV can be observed with infrared videoscopy in patients affected by HC-BPPV. The origin of this Ny is most likely due to a natural inclination of horizontal semicircular canal with respect to the horizontal plane. This Ny stops after flexion of the head in neutral position, and for this reason, it should be considered as a seemingly spontaneous Ny. This Ny, in our experience, is observed in most HC-BPPV patients but does not indicate the need for a different management protocol or any different prognostic value of HC-BPPV.

Abstract
Familial hemiplegic migraine (FHM) is a rare type of migraine with aura. Mutations in three genes have been described in FHM patients: CACNA1A (FHM1), ATP1A2 (FHM2) and SCN1A (FHM3). We screened 27 Spanish patients with hemiplegic migraine (HM), basilar-type migraine or childhood periodic syndromes (CPS) for mutations in these three genes. Two novel CACNA1A variants, p.Val581Met and p.Tyr1245Cys, and a previously annotated change, p.Cys1534Ser, were identified in individuals with HM, although they have not yet been proven to be pathogenic. Interestingly, p.Tyr1245Cys was detected in a patient displaying a changing, age-specific phenotype that began as benign paroxysmal torticollis of infancy, evolving into benign paroxysmal vertigo of childhood and later becoming HM. This is the first instance of a specific non-synonymous base change being described in a subject affected with CPS. The fact that the molecular screen identified non-synonymous changes in< 15± of our HM patients further stresses the genetic heterogeneity underlying the presumably monogenic forms of migraine.

Abstract
OBJECTIVE The aim of this work is to establish if the vestibular evoked myogenic potentials (VEMPs) could be used as a clinical test of vestibular function in children. MATERIALS AND METHODS Forty normal hearing children, aged between 3 and 15 years, and classified in preschool and scholar group, have been investigated in order to study normal development of vestibular potentials and to define fundamental parameters of VEMPs, establishing normal data of latencies and amplitude ratio. Electromyographic activity of sternocleidomastoid muscle was recorded while children were laid supine on a bed and asked to raise their head off of the bed in order to activate their neck flexors bilaterally. The saccular receptors were acoustically stimulated with a logon of 500Hz at an intensity of 130dB peSPL presented monaurally through earphones. In each recording, we analysed latencies and amplitudes of the p13 and n23 waves and the amplitude ratio between the two ears. RESULTS VEMPs were normally detected in all subjects. In preschool group mean p13 and mean n23 latencies were, respectively, 16.13 (+/-2.12)ms and 21.17 (+/-2.77)ms; mean amplitude ratio was 28.49 (+/-18.10). In scholar group mean p13 and n23 were respectively 16.14 (+/-3.48)ms and 21.78 (+/-3.39)ms, while mean amplitude ratio 20.44 (+/-13.24). Comparison of latencies and amplitude ratio between the children groups and control adult group did not showed any significant differences. CONCLUSION In conclusion, VEMPs could represent a valid and non-invasive technique able to investigate vestibular function in children and, in particular, vestibulo collic reflex.

Abstract
OBJECTIVE Vertigo in childhood is a complaint consisting of a wide spectrum of diagnoses. The aim of this study was to evaluate pediatric patients with vertigo with normal eardrum and middle ear findings and discuss the differential diagnoses. METHODS Patient records of 50 children under 18 years of age with vertigo as the chief complaint, examined at the Baskent University, Research and Application Centers at Konya and Adana otorhinolaryngology clinics between May 2003 and October 2005 were retrospectively reviewed. The questionnaires, laboratory tests including blood samples, audiological and vestibular tests, and final diagnoses were analyzed. Patients with perforated eardrums, otitis media with effusion, and acute upper respiratory tract infections were not included in the study. RESULTS The study group consisted of 50 patients (33 females, 66%; 17 males, 34%), between 4 and 17 years of age (mean age, 11.5+/-3.9 years). Severe sensorineural hearing loss was present in one patient unilaterally (2%) and one patient bilaterally (2%). Bilateral low-frequency sensorineural hearing loss was present in one patient (2%). Electronystagmography revealed central vestibular abnormalities in three patients (6%). Canal paresis was established in six patients (12%). The Dix-Hallpike test was positive in six patients (12%). The most frequent cause of vertigo was migraine, occurring in 34% of patients (n=17). Other less-frequent etiologies of vertigo were benign paroxysmal vertigo (n=6; 12%), benign paroxysmal positional vertigo (n=6; 12%), psychogenic vertigo (n=5; 10%), epilepsy (n=3; 6%), metabolic disorders (n=3; 6%), vestibular neuritis (n=2; 4%), Meniere's disease (n=1; 2%), perilymphatic fistula (n=1; 2%), amblyopia (n=1; 2%), and unclassifiable (n=5; 10%). CONCLUSIONS Migraine was found to be the most frequent presenting diagnosis in childhood vertigo, although several peripheral vestibular disorders also were diagnosed. Evaluation of vertigo in childhood should begin with a thorough neuro-otologic evaluation and include other relevant multidisciplinary team members as needed to avoid unnecessary effort and cost.

Abstract
BACKGROUND Causes of benign episodic vertigo in paediatric age include benign paroxysmal vertigo of childhood (BPV) and benign paroxysmal positional vertigo (BPPV). OBJECTIVE The aim is to review the clinical, audiological and vestibular findings in a cohort of children with BPV and in a group of children with BPPV and to highlight the differences useful to formulating a differential diagnosis. METHODS Eighteen children, aged 4-9 years, consecutively examined for paroxysmal attacks of dizziness and/or vertigo attacks between January 2002 and December 2002 entered our study. The clinical characteristics of vertigo, presence of triggering factors, family history of migraine, presence of motion sickness, migraine and other accompanying symptoms were considered. Neurological, ophthalmologic, vestibular and auditory functions were assessed. RESULTS Eight children suffered from BPPV and ten children from BPV. In the BPPV group, the vestibular examination was normal except for the Dix-Hallpike maneuver. Liberatory maneuvers were immediately effective in all patients and all remained symptom-free during the follow-up. In the BPV group, the vestibular examination was positive in 3 patients but none had positive Dix-Hallpike maneuver. All patients with BPV have a positive family history of migraine and seven had a history of motion sickness. In all, migraine was present one year before the vertigo symptoms, with a frequency of at least two migraine episodes a month. CONCLUSION BPV differs from BPPV in terms of family history, clinical symptoms, otoneurological signs, therapy and clinical evolution. BPPV is characterized by specific otoneurological signs, and must be treated with liberatory maneuvers: neither medical therapy nor strict follow-up is needed.

Abstract
PURPOSE OF REVIEW This review focuses on prospective studies of vertigo and balance therapy in the past 3 years, including advances in vertigo-habituation exercises for adults, pediatric intervention, and virtual reality techniques, and, in more depth, the literature pertinent to driving motor vehicles. RECENT FINDINGS Increased support has been generated for the efficacy of a minimal, home-based vertigo-habituation program for adults with peripheral vestibular disorders. Vestibular rehabilitation has been shown to be associated with improvements in independence and dynamic visual acuity. Community-based vestibular rehabilitation has been shown to be efficacious for selected patients, after careful screening, when trained personnel provide intervention. Vestibular rehabilitation has been incorporated into the rehabilitation program for head-injured military personnel who will be returned to duty, and multifactorial balance rehabilitation has been shown to be useful for children with hearing and balance impairments. Virtual reality techniques have made significant advances, so immersive environments have potential for rehabilitation for patients with vestibular disorders and for developing training regimens for astronauts to ameliorate some effects of exposure to microgravity. Driving skill, in general, is affected by use of benzodiazepines. For many patients with vestibular impairments driving is a particularly problematic activity of daily living. SUMMARY Progress has been made in studies of acute care, community-based, and pediatric vestibular rehabilitation. Work on simulator-based paradigms has moved toward readiness for implementation. Studies of driving have provided some insight into the problems of these patients. More work remains to be done on all of these problems.

Abstract
Background. Benign paroxysmal torticollis (BPT) is an episodic functional disorder of unknown etiology, characterized by the periods of torticollic posturing of the head, that occurs in the early months of life in healthy children. Case report. We reported two patients with BPT. In the first patient the symptoms were observed at the age of day 20, and disappeared at the age of 3 years. There were 10 episodes, of which 2 were followed by vomiting, pallor, irritability and the abnormal trunk posture. In the second patient, a 12-month-old girl, BPT started from day 15. She had 4 episodes followed by vomiting in the first year. Both girls had the normal psychomotor development. All diagnostical tests were normal. Conclusion. The recognition of BPT, as well as its clinical course may help to avoid not only unnecessary tests and the treatment, but also the anxiety of the parents.

Abstract
OBJECTIVE Dizziness and imbalance are uncommon in children, but often alarming for their families: a detailed interview and otoneurological examination are important for reaching a specific diagnosis and treatment. Children with vestibular disorders are thought to be difficult to examine: vestibular tests (caloric test, roto-acceleratory test, electronystagmography, opto-kinetic nystagmus, cranio-corpography and posturography) are used less frequently for children than in adult patients. The aim of the study was to determine whether the results of electronystagmography testing improve an emergency physician's diagnosis of dizziness in children. METHODS Patients were selected on the basis of the following inclusion criteria: aged between 2 and 12 years and affected with vertiginous symptoms. All patients underwent the following instrumental examinations: blood tests, audiological screening, electronystagmography of spontaneous nystagmus or provoked by vestibular and optical stimulation and electroencephalogram. RESULTS The results underlines an high incidence of central vertigo (83%): 52% of the children presented a prevailing unidirectional nystagmus at labyrinth stimulation and 48% of the children an asymmetry in the response of nystagmus at optical kinetic stimulation with quality alteration of shocks. CONCLUSIONS Electronystagmography can register and evaluate the qualitative and quantitative characteristics of the nystagmic response and allow to distinguish between central or peripheric vertigo: different degrees and various combinations of the abnormal responses shown in optokinetic central test were the most characteristic of electronystagmography in patients with vestibular central vertigo.

Abstract
This paper will discuss therapeutic possibilities for disorders of the vestibular organs and the neurons involved, which confront ENT clinicians in everyday practice. Treatment of such disorders can be tackled either symptomatically or causally. The possible strategies for restoring the body's vestibular sense, visual function and co-ordination include medication, as well as physical and surgical procedures. Prophylactic or preventive measures are possible in some disorders which involve vertigo (bilateral vestibulopathy, kinetosis, height vertigo, vestibular disorders when diving (Tables 1 (Tab. 1) and 2 (Tab. 2)). Glucocorticoid and training therapy encourage the compensation of unilateral vestibular loss. In the case of a bilateral vestibular loss, it is important to treat the underlying disease (e.g. Cogan's disease). Although balance training does improve the patient's sense of balance, it will not restore it completely.In the case of Meniere's disease, there are a number of medications available to either treat bouts or to act as a prophylactic (e.g. dimenhydrinate or betahistine). In addition, there are non-ablative (sacculotomy) as well as ablative surgical procedures (e.g. labyrinthectomy, neurectomy of the vestibular nerve). In everyday practice, it has become common to proceed with low risk therapies initially. The physical treatment of mild postural vertigo can be carried out quickly and easily in outpatients (repositioning or liberatory maneuvers). In very rare cases it may be necessary to carry out a semicircular canal occlusion.Isolated disturbances of the otolith function or an involvement of the otolith can be found in roughly 50% of labyrinth disturbances. A specific surgical procedure to selectively block the otolith organs is currently being studied. When an external perilymph fistula involving loss of perilymph is suspected, an exploratory tympanotomy involving also the round and oval window niches must be carried out. A traumatic rupture of the round window membrane can, for example, also be caused by an implosive inner ear barotrauma during the decompression phase of diving. Dehiscence of the anterior semicircular canal, a relatively rare disorder, can be treated conservatively (avoiding stimuli which cause dizziness), by non-ablative "resurfacing" or by "plugging" the semicircular canal. A perilymph fistula can cause a Tullio-phenomenon resulting from a traumatic dislocation or hypermobility of the stapes, which can be surgically corrected. Vestibular disorders can also result from otosurgical therapy. When balance disorders persist following stapedectomy it is necessary to carry out a revision operation in order to either exclude a perilymph fistula or shorten the piston. Surgically reducing the size of open mastoid cavities (using for example porous hydroxylapatite or cartilage) can result in a reduction of vertiginous symptoms while nursing or during exposure to ambient air. Vestibular disturbances can occur both before and after vestibular nerve surgery (acoustic neuroma). Initially, good vestibular compensation can be expected after surgically removing the acoustic neuroma. An aberrant regeneration of nerve fibers of the vestibulocochlear nerve has been suggested as a cause for secondary worsening. Episodes of vertigo can be caused by an irritation of the vestibular nerve (vascular loop). Neurovascular decompression is generally regarded as the best surgical therapy. In the elderly, vestibular disturbances can severely limit quality of life and are often aggravated by multiple comorbidities. Antivertiginous drugs (e.g. dimenhydrinate) in combination with movement training can significantly reduce symptoms. Administering antivertiginous drugs over varying periods of time (e.g. transdermal scopolamine application via patches) as well as kinetosis training can be used as both prophylactically and as a therapy for kinetosis. Exposure training should be used as a prophylactic for height vertigo.

Abstract
OBJECTIVE To determine which common, nonpharmacological, nonsurgical treatments are most effective for treatment of benign paroxysmal positional vertigo (BPPV). STUDY DESIGN Prospective, randomized, sham-controlled. PATIENTS Patients (n = 124) with BPPV of the posterior semicircular canal. SETTING Tertiary care center. INTERVENTIONS Random assignment to one of five groups: modified canalith repositioning maneuver (CRP), modified liberatory maneuver (LM), sham maneuver, Brandt and Daroff's exercise, and vertigo habituation exercises. Subjects received a standard educational lecture about BPPV and the purpose of the intervention. No vestibular-suppressant medication or special instructions for head positioning were used. Post-tests were given at 1 week after treatment and at approximately 3 months and 6 months later. MAIN OUTCOME MEASURES Vertigo intensity and frequency. RESULTS Multilevel analyses showed that vertigo decreased significantly after LM, CRP, and Brandt-Daroff exercise; those three groups did not differ significantly. The habituation group did not differ from sham, Brandt-Daroff, LM, or CRP groups. Changes in scores were maintained throughout the 6-month follow-up period. CONCLUSION LM, CRP, and exercises are all effective interventions; patient education plus the sham maneuver, however, had some beneficial effect. These results support two possible mechanisms of BPPV: displaced otoconia and a neural mechanism affecting interpretation of semicircular canal signals.
