Abstract
OBJECTIVES To evaluate the therapeutic efficacy of the forced prolonged position (FPP) in patients with horizontal semicircular canal (HSCC) cupulolithiasis in whom the cupulolith repositioning maneuver (CuRM) failed. METHODS Fifty-four consecutive patients with HSCC cupulolithiasis were included, and immediate treatment efficacy of CuRM and short-term treatment efficacy of FPP were investigated. RESULTS We performed the CuRM in HSCC cupulolithiasis, and, if the CuRM did not show immediate success, instructed the patients to perform the FPP or the sham position (by random allocation) at home. The immediate therapeutic success of the CuRM was assessed by the absence of nystagmus and vertigo on positional testing after 30 minutes of the maneuver, which was 14.8% on the first visit day. And the resolution rate of HSCC cupulolithiasis was higher in the FPP group than in the sham position group at the second (78.3% vs 55.6%), third (75.0% vs 42.9%), and fourth visits (100% vs 25.0%). CONCLUSION Although the CuRM has been considered to be a good therapeutic option for HSCC cupulolithiasis because it theoretically aims to detach otoconial particles attached both on the utricle and canal sides of the cupula, the immediate success rate was only 14.8% at the first visit. The FPP can be additionally recommended to improve the resolution rate in HSCC cupulolithiasis patients in whom the CuRM fails.

Abstract
Direction-changing positional nystagmus (DCPN), which refers to the change in the direction of nystagmus with different head positions, is a well-known characteristic of horizontal semicircular canal BPPV. The supine head roll test is commonly used to diagnose horizontal canal BPPV. However, persistent geotropic DCPN observed during this test cannot be explained by the conventional explanations of canalolithiasis or cupulolithiasis. To account for this unique nystagmus, the concept of a "light cupula" has been recently introduced. In this review, we provide an overview of the historical background, clinical features and diagnostic methods, proposed mechanisms, and treatment strategies associated with the light cupula phenomenon based on the available literature to date.

Abstract
(1) Background: Usually, the majority of patients suffering from vertigo and dizziness can be identified in four major categories: acute spontaneous vertigo, episodic (recurrent) vertigo, recurrent positional vertigo, and chronic imbalance. Our purpose is to retrospectively evaluate the main causes of episodic vertigo and to find indications for a reliable clinical suspicion useful for a definitive diagnosis, comparing patients affected by different presenting symptomatology (acute vertigo, recurrent episodic vertigo, and imbalance). (2) Methods: we retrospectively evaluated the clinical records in a population of 249 consecutive patients observed for vertigo in our tertiary referral center in the period 1 January 2019-31 January 2020. On the basis of the reported clinical history, patients were divided into three groups: patients with their first ever attack of vertigo, patients with recurrent vertigo and dizziness, and patients with chronic imbalance. (3) Results: On the basis of the results of the instrumental examination, we arbitrarily divided (for each type of symptoms) the patients in a group with a normal vestibular instrumental examination and a group of patients in which the clinical-instrumental evaluation showed some pathological results; a highly significant difference (p: 0.157) was found between recurrent and acute vertigo and between recurrent vertigo and imbalance. (4) Conclusions: Patients with recurrent vertigo more frequently exhibit a negative otoneurological examination since they are often examined in the intercritical phase. A precise and in-depth research of the patient's clinical history is the key to suspect or make a diagnosis together with the search for some instrumental or clinical hallmark, especially in cases where the clinical picture does not fully meet the international diagnostic criteria.

Treatment Efficacy of Various Maneuvers for Lateral Canal Benign Paroxysmal Positional Vertigo With Apogeotropic Nystagmus: A Randomized Controlled Trial. Clin Exp Otorhinolaryngol 2023; 16:251-258. [PMID: 37499698 PMCID: PMC10471904 DOI: 10.21053/ceo.2023.00619] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2023] [Revised: 07/06/2023] [Accepted: 07/26/2023] [Indexed: 07/29/2023] Open
Abstract
OBJECTIVES The aim of this study was to determine the most effective treatment approach by comparing the impacts of various otolith reduction techniques in patients with apogeotropic lateral semicircular canal benign paroxysmal positional vertigo (LC-BPPV). METHODS We performed a multicenter randomized prospective study from January to December 2015, involving 72 consecutive patients with apogeotropic LC-BPPV. The patients were divided into three treatment groups: therapeutic head-shaking (group A), the Gufoni-Appiani maneuver (group B), and the cupulolith repositioning maneuver (CuRM; group C). Each group underwent evaluation and treatment up to the fourth week. Treatment success was defined as the disappearance of positional vertigo and nystagmus. RESULTS This study included 72 patients (49 male and 23 female), with a mean (±standard deviation) age of 55.4±13.5 years. The mean duration of vertigo experienced prior to treatment was 3.9±4.4 days. The mean latency and duration of nystagmus were 2.7±3.0 seconds and 47.9±15.8 seconds, respectively. The overall treatment frequency was 2.0±0.9. The number of treatments differed significantly among the three groups (P<0.05). After 4 weeks, the success rates for groups A, B, and C were 90.5%, 92.3%, and 100%, respectively. No significant difference was observed in the success rate across treatment. METHODS and periods (P>0.05). However, CuRM was the only method with a 100% treatment success rate. CONCLUSION While no clear difference was observed among the three treatments for LC-BPPV, CuRM was found to be superior to the other approaches in the long term.

Abstract
OBJECTIVE To investigate the incidence of benign paroxysmal positional vertigo subtype by hospital visit type (i.e. out-patient department vs emergency room), in a single tertiary referral centre. METHODS A total of 772 consecutive patients with benign paroxysmal positional vertigo were included. Using head-roll and Dix-Hallpike tests, benign paroxysmal positional vertigo subtype was determined as canalolithiasis posterior semicircular canal benign paroxysmal positional vertigo, geotropic horizontal semicircular canal benign paroxysmal positional vertigo or apogeotropic benign paroxysmal positional vertigo. RESULTS The posterior semicircular canal benign paroxysmal positional vertigo patients who were evaluated via the out-patient department outnumbered those evaluated via the emergency room, while those with horizontal semicircular canal benign paroxysmal positional vertigo who were evaluated via the emergency room outnumbered those evaluated via the out-patient department. CONCLUSION A significantly higher proportion of patients who visited the emergency room had horizontal semicircular canal benign paroxysmal positional vertigo than posterior semicircular canal benign paroxysmal positional vertigo. These results suggest that the true incidence of horizontal semicircular canal benign paroxysmal positional vertigo might be higher than previously reported.

Abstract
Purpose The present study investigated the impact of coronavirus disease 2019 (COVID-19) pandemic on benign paroxysmal positional vertigo (BPPV). Patients and Methods The medical records of BPPV patients who were evaluated in the outpatient department (OPD) and emergency room (ER) during (435 patients) and before (517 patients) the COVID-19 pandemic were retrospectively reviewed. Dix-Hallpike and supine head-roll tests were used to classify the subtype of BPPV as posterior semicircular canal (PSCC), geotropic lateral semicircular canal (geotropic LSCC), or apogeotropic lateral semicircular canal (apogeotropic LSCC) BPPV. Results More patients with PSCC BPPV were diagnosed at the OPD compared with those who were diagnosed at the ER both before and during the COVID-19 pandemic; however, more patients with LSCC BPPV were diagnosed at the ER compared with those who were diagnosed at the OPD during the same periods. The mean time interval between vertigo onset and initial evaluation was remarkably longer during the pandemic in patients with PSCC BPPV. Conclusion This study demonstrated that the incidences of BPPV subtypes according to hospital visit type were not significantly different before and during the COVID-19 pandemic. Because hospital visits were delayed in patients with PSCC BPPV during the COVID-19 pandemic, telemedicine or e-health could be suitable alternatives to face-to-face medical care for these patients.

Abstract
Background: There are debates on whether mastoid oscillation has any benefit or harm in treating horizontal semicircular canal (HSCC) cupulolithiasis. The goal of this study was to investigate the therapeutic effects of the new maneuver using only inertia and gravity and compare it with the previously reported cupulolith repositioning maneuver using mastoid vibration (CuRM). Methods: We enrolled 57 patients diagnosed with HSCC cupulolithiasis. Patients were randomly allocated to the previously reported CuRM or the new maneuver (briefly, 30° head rotation to the affected side and thereafter bidirectional side-lying) using simply inertia and gravity, and their immediate and short-term effects were evaluated. Results: The immediate success rate did not differ significantly between the CuRM (8 of 22, 36.4%) and the new maneuver (10 of 35, 28.6%) groups (p = 0.538, Pearson’s chi-square test). The late resolution rates at the first follow-up of the CuRM (75%, 9 of 12) and new maneuver groups (82.6%, 19 of 23) were very high, and there was no statistical difference between them (p = 0.670, Fisher’s exact test). Conclusions: This study showed that the new maneuver was effective for treating HSCC cupulolithiasis with an immediate success rate of 28.6% (10 of 35). Although it did not show better results than the existing maneuver using vibration, there was no statistical difference. Considering the debate on the effectiveness of oscillation, we believe our new maneuver is a conservative alternative that uses only inertia and gravity, and it can be easily performed in clinics where oscillation equipment is not available.

Abstract
Benign paroxysmal positional vertigo (BPPV) is a very common condition in the population and an important cause of acute vertigo or dizziness in patients presenting to an emergency department (ED). Despite this, abundant evidence shows that current ED management of patients with BPPV is suboptimal. Common ED management processes include brain imaging and treatment with vestibular suppressant medications such as meclizine, neither of which is recommended by current guidelines. The most efficient management of BPPV is to perform a bedside test (Dix-Hallpike test) and then to treat the patients with a bedside positional (the Epley) maneuver. In this practical review we emphasize the efficient management for the most common form of BPPV-posterior canal BPPV. Using this management will reduce resource utilization (laboratory testing, brain imaging, specialist consultation), reduce ED length of stay, and reduce use of ineffective mediations that have side effects but little therapeutic effect. Application of these practices would improve important patient-centered outcomes such as symptom reduction, radiation exposure, side effects from medications, and less need for urgent follow-up with another health care provider. The article also discusses the approach to patients in whom the Dix-Hallpike and/or Epley maneuvers do not seem to work. This includes a discussion the second most common variant of BPPV (horizontal canal BPPV) and criteria for safe discharge of patients. Another important advantage of learning BPPV best practices is that it is enormously satisfying for the clinician, not unlike treating a child with a nursemaid's elbow.

Abstract
BACKGROUND Benign paroxysmal positional vertigo is classified into five subtypes according to the features of positional nystagmus: lateral canalolithiasis, lateral light cupula, lateral heavy cupula, posterior canalolithiasis and posterior heavy cupula. OBJECTIVES The first aim of the study was to clarify whether the lateral canal type or posterior canal type was more common. The second aim of the study was to assess the aetiology of benign paroxysmal positional vertigo by investigating the onset time of each subtype. METHODS The subjects were 512 consecutive patients with benign paroxysmal positional vertigo. The patients were prospectively aggregated, and interviews were used to evaluate onset time. RESULTS The lateral canal type (55.5 per cent) was more common than the posterior canal type (44.5 per cent). Time of awakening was the most common onset time in every subtype. CONCLUSION The incidence of lateral canal type is higher than that of posterior canal type. The aetiology of benign paroxysmal positional vertigo is closely related to sleep.

Abstract
OBJECTIVE To examine the treatment effects of repositioning maneuvers with the head turned 45° downwards (Gufoni maneuver) and 45° upwards (Appiani maneuver) in 25 patients with ageotropic horizontal semicircular canal (HSCC) benign paroxysmal positional vertigo (BPPV). METHODS Patients were randomly assigned to the Gufoni or Appiani maneuvers, and their immediate and short-term efficacy was investigated. RESULTS The immediate treatment response was successful in four of 16 patients who were treated with the Appiani maneuver and were not successful in any of the nine patients treated with the Gufoni maneuver. The patients who showed spontaneous resolution during follow-up outnumbered the patients who showed resolution of ageotropic HSCC BPPV immediately after the repositioning maneuvers. CONCLUSION This study showed a very low immediate resolution rate of ageotropic HSCC BPPV after the Gufoni maneuver; this may be attributed to the less effectiveness of the Gufoni maneuver against debris that often exists in the canal side of the cupula. Another interesting finding was that the rate of spontaneous resolution during the follow-up period was higher than that of immediate resolution after the repositioning maneuvers, which may support the recently proposed hypothesis that ageotropic positional nystagmus can also be evoked by causes other than the otolithic attachment on the cupula, such as a slight change in the biochemical composition of the inner ear fluids.

Abstract
OBJECTIVE This study aimed to assess the long-term recurrence rate and correlations between recurrence and potential risk factors in patients with benign paroxysmal positional vertigo (BPPV). DESIGN A total of 548 consecutive patients who demonstrated typical posterior or horizontal BPPV between January 2010 and December 2012 were included in this prospective study. All patients were contacted by phone every 6 months for 5 years and were asked to revisit the clinic when they experienced positional vertigo to be reexamined for recurrence. Recurrence of BPPV was defined as having positional vertigo and nystagmus confirmed following a symptom-free period of at least 7 days after complete resolution. We assessed the 5-year recurrence rate of BPPV, and the time point of recurrence in all patients as well as the risk factors of BPPV recurrence, including the clinical characteristics, therapeutic results of BPPV, and various comorbidities. RESULTS Among the 548 patients, 121 (22.1 %) had at least one recurrence. Of these, 78 patients (54.5%) had only one recurrence within 5 years, while 43 (45.5%) patients experienced two or more recurrences. A recurrence occurred within 1 year in 82 patients (67.8%). The Cox proportional hazard ratio analysis found that head trauma (p = 0.015), Meniere's disease (p = 0.016), the number of canalith repositioning procedures performed (p = 0.037), and the number of previous vertigo attacks (p = 0.038) were significant risk factors of BPPV recurrence as opposed to hypertension or hyperlipidemia. CONCLUSIONS The recurrence rate of BPPV was 22.1% at 5 years after the initial treatment. About 70% of recurred patients had a recurrence within 1 year. Head trauma, ipsilateral Meniere's disease, the number of canalith repositioning procedures performed, and the number of previous vertigo attacks were significant risk factors of BPPV recurrence.

Treatment Results of Geotropic and Apogeotropic Horizontal Canal Benign Paroxysmal Positional Vertigo in a Tertiary Dizziness Clinic. Front Neurol 2021; 12:720444. [PMID: 34349726 PMCID: PMC8326322 DOI: 10.3389/fneur.2021.720444] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2021] [Accepted: 06/24/2021] [Indexed: 12/02/2022] Open
Abstract
Purpose: To determine the effectiveness of our treatment protocol for geotropic and apogeotropic horizontal canal benign paroxysmal positional vertigo (h-BPPV). Methods: We retrospectively evaluated patients with newly diagnosed geotropic and apogeotropic h-BPPV who visited our clinic between July 2017 and December 2019. Patients were treated according to our treatment protocol, which was implemented in 2017. Patients with geotropic h-BPPV were preferably treated with the Gufoni maneuver. In patients with apogeotropic h-BPPV we executed the modified Gufoni maneuver to achieve conversion to the geotropic type. We looked at the number of successful treatments and the number of recurrences within 1 year. Results: We included 102 patients with h-BPPV, 62 (61%) of whom were treated for geotropic h-BPPV. The ratio of apogeotropic to geotropic h-BPPV was 0.65. After the first visit, we observed resolution of horizontal canal BPPV in 71 and 63% of the geotropic and the apogeotropic group, respectively. After the second visit, this percentage increased to 92% for geotropic h-BPPV and 78% for apogeotropic h-BPPV. After 1 year of follow-up we determined a recurrence rate of 32 and 24% for the geotropic and apogeotropic group, respectively. Conclusion: With our treatment protocol we managed to achieve high rates of symptom resolution in the geotropic and apogeotropic type of h-BPPV with acceptable recurrence rates. We observed a relatively high ratio of apogeotropic h-BPPV to geotropic h-BPPV.

Abstract
PURPOSE OF REVIEW This article provides a summary of the evaluation and treatment of patients presenting with episodic positional dizziness. RECENT FINDINGS Positional components are nearly ubiquitous among diagnoses of dizziness, so it can be challenging to classify patients with episodic positional dizziness simply based on the history of present illness. Overreliance on the presence of a report of positional components has likely resulted in misapplication or misinterpretation of positional testing and negative experiences with maneuvers to treat positional dizziness. The prototypical episodic positional dizziness disorder is benign paroxysmal positional vertigo (BPPV). BPPV is caused by free-floating particles in a semicircular canal that move in response to gravity. The diagnosis is made by identifying the characteristic patterns of nystagmus on the Dix-Hallpike test. Particle repositioning for BPPV is supported by randomized controlled trials, meta-analyses, and practice guidelines. Other disorders that can present with episodic positional dizziness are migraine dizziness, central lesions, and light cupula syndrome. SUMMARY Episodic positional dizziness is a common presentation of dizziness. Neurologists should prioritize identifying and treating BPPV; doing so provides an important opportunity to deliver effective and efficient care. Providers should also recognize that positional components are common in most causes of dizziness and, therefore, should not over-rely on this part of the history of presentation when considering the diagnosis and management plan.

Abstract
Objective We aimed to describe the clinical features of the apogeotropic variant of horizontal canal benign paroxysmal positional vertigo (HC BPPV-AG) in a cluster of patients with restrictive neck movement disorders and a new therapeutic manoeuvre for its management. Methods In a retrospective review of cases from an ambulatory tertiary referral center, patients with HC BPPV-AG in combination with neck movement restriction that prevented any classical manual repositioning procedure or who were refractory to canalith repositioning manoeuvres, were treated with a new manoeuvre comprised of sequential square-wave pattern of head and body supine rotations while nystagmus was being monitored, until either an apogeotropic to geotropic conversion or resolution of the nystagmus was observed. Results Fifteen patients were studied. All but one [14/15 cases] showed a positive therapeutic response to the repositioning procedure in a single session. In two cases, a direct relief of vertigo and elimination of nystagmus was observed without an intermediate geotropic phase. Although in three patients the affected ear was not initially identified, it was ultimately identified and successfully treated by the square wave manoeuvre in all of them. Conclusions The square-wave manoeuvre is an alternative for HC BPPV-AG treatment in either cases with neck restriction, where the affected side is not well identified at the bedside or when other manoeuvres fail to resolve the HC BPPV-AG.

Abstract
OBJECTIVES To compare the effect of a high-speed barbecue maneuver with the modified Lempert maneuver and sham in patients with benign paroxysmal positional vertigo (BPPV) of the horizontal canal. METHODS Randomized sham-controlled, single blinded multicenter clinical trial in two university hospitals investigating consecutive patients with horizontal canal BPPV.Patients were randomly assigned to high-speed barbecue (HSB), modified Lempert maneuver (ML), or sham maneuver (SM). All treatments were performed in a biaxial rotational chair with weekly follow-up to a maximum of three treatment sessions. The final follow-up was 3 months after the last treatment. RESULTS Primary outcome: 2-week recovery rate per protocol. Secondary outcome: Cumulative recovery rate and Dizziness Handicap Inventory (DHI) scores after 3 months per protocol (HSB and ML) and intention to treat (all groups).Fifty-four patients were analyzed after 2 weeks (HSB = 17; ML = 20; SM = 17). Two-week recovery rate was 14/17 after HSB, 11/20 after ML, and 4/17 after SM, with significantly better recovery in HSB [OR 15.17, 95% CI (1.85, 124.63), P = .001] using sham as base level. Recovery rate after 3 months was 15/17 after HSB and 15/19 after ML. Cumulative recovery rate showed no significant differences between the two treatment groups [95% CI (0.30, 13.14), P = .46] in cure rate DHI [95% CI (-16.56, 15.02), P = .92]. No unexpected adverse events were observed. CONCLUSION Velocity change in horizontal canal BPPV treatment gives a faster initial recovery. Rapid recovery could reduce the disease burden.

Abstract
Benign paroxysmal positional vertigo (BPPV) represents the most common form of positional vertigo. It is caused by dislodged otoconia that freely float in the semicircular canals (canalolithiasis) or attach to the cupula (cupulolithiasis). A cupulolithiasis-type (or a heavy cupula-type) of BPPV implicating the lateral semicircular canal (LSCC) exhibits persistent ageotropic direction-changing positional nystagmus (DCPN) in a head-roll test. However, in some cases, unlike any type of BPPV, persistent geotropic DCPN cannot be explained by any mechanisms of BPPV, and don't fit the current classifications. Recently, the notion of light cupula has been introduced to refer to the persistent geotropic DCPN. In this study, we looked at the clinical features of light cuplula and discussed the possible mechanisms and therapeutic strategies of the condition. The notion of light cupula is a helpful addition to the theory of peripheral positional vertigo and nystagmus.

Abstract
Backgrounds: Although various therapeutic maneuvers have been proposed, it is still unclear which maneuver is better to treat apogeotropic horizontal canal benign paroxysmal positional vertigo (HC-BPPV).Objectives: This study aimed to assess the therapeutic efficacy of the cupulolith repositioning maneuver (CuRM) in apogeotropic HC-BPPV in comparison with the therapeutic head-shaking maneuver and modified Lempert maneuver.Materials and Method: This is double-blind randomized prospective study. Forty-nine consecutive patients diagnosed with apogeotropic HC-BPPV were allocated randomly to CuRM (n = 18), therapeutic head-shaking (n = 16), or modified Lempert maneuver (n = 15). The presence of nystagmus and vertigo on positional testing were evaluated at 30 min, on 1 day, and 1 week after treatment.Results: There were no significant differences in any clinical characteristics between the three groups at randomization. After a single trial of therapeutic maneuvers on the initial visit day, the CuRM (38.9%) and therapeutic head shaking maneuver (12.5%) did not show differences compared to modified Lempert maneuver (33.3%). The therapeutic effects on the 2nd day and at 1 week after treatment also did not differ between the three groups.Conclusions: Although the CuRM is theoretically considered to be a better therapeutic method, the therapeutic efficacy of CuRM was not statistically different compared to the other two maneuvers.

Abstract
Objective: Otolin-1, a main specific otoconia matrix protein, passes through the labyrinth-blood barrier and is detectable in peripheral blood. Serum otolin-1 levels differ between patients with benign paroxysmal positional vertigo (BPPV) and healthy controls and are significantly age-related, increasing in healthy controls with age, suggesting that serum otolin-1 levels reflect otolith status. The aim of this study was to determine whether otolin-1 levels change during vertigo episodes in patients with BPPV and whether any change is specific and sensitive enough for BPPV episodes. Method: Patients diagnosed with de novo idiopathic BPPV during an acute episode were included in the study from May 2017 to May 2018. Blood samples were drawn before patients were treated with canalith-repositioning maneuvers. Serum otolin-1 levels were compared between 78 patients and 121 age- and sex-matched healthy individuals. Results: There were no significant differences between the groups in the age distribution, sex ratio, body mass index, clinical history, routine blood parameters, or total protein, albumin, uric acid, creatinine, blood urea nitrogen and lipid profiles (P > 0.05). Serum levels of otolin-1 were significantly higher in BPPV patients than in healthy controls (P < 0.001). Receiver operating characteristic analysis revealed that a serum otolin-1 value of 299.45 pg/ml was the optimal cut-off value to discriminate patients with BPPV from healthy controls (area under the curve 0.757, 95% CI 0.687~0.826) with a sensitivity of 67.9% and a specificity of 72.7%. Conclusion: Serum levels of otolin-1 may be a potential biomarker for BPPV episodes.

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.

Abstract
The apogeotropic variant of horizontal semicircular canal benign paroxysmal positional vertigo (HC-BPPV) is attributed to free floating particles in the anterior arm of the lateral semicircular canal – particles attached to the cupula facing the canal or particles attached to the cupula facing the utricle. Zuma e Maia described a new treatment for both canalithiasis of the anterior arm of the horizontal semicircular canal (HC) and cupulolithiasis of the HC. Seventeen patients with apogeotropic HC-BPPV were enrolled and treated with Zuma’s Maneuver. During the repositioning of the particles to the utricule, we observed the direction of the nystagmus evoked in each step of this maneuver in order to know where the otoliths were probably located. Eight patients were diagnosed with canalithiasis of the anterior arm, six patients with cupulolithiasis with the particles facing the canal and three patients with cupulolithiasis with the particles facing the utricle. Our data suggest that we can assume where the otoliths are probably located by observing the pattern of the nystagmus evoked in each step of the Zuma’s Maneuver in patients with apogeotropic HC-BPPV.

Abstract
PURPOSE Benign paroxysmal positional vertigo (BPPV) is diagnosed and divided into subtypes based on positioning vertigo and nystagmus. Whether these subtypes entail any significant differences in patient-reported symptoms; is yet not known. Such differences may have clinical and therapeutic consequences. Our aim was to assess dizziness handicap and clinical characteristics of posterior and lateral canal BPPV. METHODS This prospective observational multicentre study analysed consecutive patients with BPPV, confirmed by standardized procedures including videonystagmography under diagnostic manoeuvres in a biaxial rotational chair. Patients were screened for other neurological and otological disorders. OUTCOMES Dizziness handicap inventory (DHI), posterior vs. lateral canal involvement. FACTORS age, gender, positional nystagmus intensity (maximum slow-phase velocity), symptom duration, 25-hydroxyvitamin D-level and traumatic aetiology. RESULTS 132 patients aged 27-90 (mean 57, SD 13) years were included. Higher DHI scores were associated with lateral canal BPPV [95% CI (1.59-13.95), p = 0.01] and female gender [95% CI (0.74-15.52), p = 0.03]. Lateral canal BPPV was associated with longer symptom duration [OR 1.10, CI (1.03-1.17), p = 0.01] and lower 25-hydroxyvitamin D-levels [OR 0.80, CI (0.67-0.95), p = 0.03]. There was no correlation between DHI scores and nystagmus intensity. CONCLUSIONS This study suggests that patients with lateral canal BPPV have increased patient-perceived disability, lower vitamin D-levels and longer duration of symptoms. This subtype might therefore require closer follow-up. Patient-perceived disability is not related to positional nystagmus intensity.

Abstract
This study aimed to observe and analyze the effects and outcomes of patients with apogeotropic direction-changing positional nystagmus (apo-DCPN) who received Gufoni maneuver.A total of 91 patients with positional vertigo admitted to the specialized dizziness clinic in Zhejiang Provincial People's Hospital from February 2014 to August 2017 were included. The immediate treatment responses to the Gufoni maneuver were observed and recorded. The patients in whom the treatment was ineffective were followed up for 4 weeks to observe the outcome of apo-DCPN.In 21 patients, the apo-DCPN was transformed after Gufoni maneuver, and 7 patients developed transformation within 4 weeks of follow-up. Spontaneous remission of apo-DCPN within the follow-up period was observed in 55 patients who were unresponsive to the Gufoni maneuver. The prevalence of migraine was significantly higher in the early remission group (P < .05) and the period between the initial visit and nystagmus remission was significantly shorter in the group of patients with migraine history (P < .05).This study demonstrates that the immediate treatment efficacy of the Gufoni maneuver is poor in positional vertigo patients with apo-DCPN. We believe that the reason for the low efficacy is that the Gufoni maneuver is only effective for some patients with apo-DCPN type HSC-BPPV. In patients with early spontaneous remission and a history of migraine, central positional nystagmus of probable vestibular migraine (VM) or benign recurrent vertigo should be considered for the mechanisms of apo-DCPN generation.

Abstract
BACKGROUND Li quick repositioning maneuver for treatment of geotropic horizontal canal benign paroxysmal positional vertigo (HC-BPPV) was reported in the literature. OBJECTIVE The aim of this study is to observe the clinical efficacy of the Li quick repositioning maneuver for the treatment of geotropic HC-BPPV. METHODS The single-blind method was used to conduct a prospective controlled study on 120 patients with geotropic HC-BPPV from May 2014 to May 2017. Patients were randomly assigned to the Li quick repositioning maneuver (Li maneuver) group or the barbecue repositioning maneuver (barbecue maneuver) group. RESULTS The successful repositioning rates were 53.3%, 70.4%, 90.7% and 92.3%, respectively, in barbecue maneuver group and 61.7%, 80.7%, 93.0% and 96.3%, respectively, in Li maneuver group at 1-day, 3-day, 1-week and 1-month follow-up. Differences in success rates of repositioning between Li and barbecue maneuver groups at 1 day, 3 days, 1 week and 1 month after initial treatment were not statistically significant using the Kaplan-Meier survival curve with a log-rank test (p = .270) . CONCLUSION The Li maneuver is a rapid, simple and efficacious repositioning method for geotropic HC-BPPV and can be widely applied in clinical practice as an alternative method.

Abstract
OBJECTIVE Clinicians sometimes see patients with relatively persistent geotropic direction-changing positional nystagmus (DCPN) as a variant of lateral semicircular canal-benign paroxysmal positional vertigo (LSCC-BPPV). Recently, the concept of a "light cupula" in the lateral semicircular canal, exhibiting persistent geotropic DCPN, has been introduced. However, the underlying pathogenesis of light cupula is not known. We investigated the efficacy of a modified cupulopathy repositioning maneuver (mCuRM), designed to reduce light debris attached to the cupula in patients with persistent geotropic DCPN. STUDY DESIGN Retrospective cohort study. METHODS Participants included 65 patients with a persistent geotropic DCPN: 35 underwent treatment (mCuRM group), and 30 were followed-up but received no treatment (No CuRM group). We compared the therapeutic and survival rate of persistent geotropic DCPN between two groups. RESULTS On Day 1, the persistent geotropic DCPN did not resolve in either group. On the first and second follow-up days, persistent geotropic DCPN was observed in 28 (80%) and 21 (60%) of patients, respectively, in the mCuRM group, and in 28 (93.3%) and 24 (80%) patients, respectively, in the no mCuRM group. The differences between groups were not statistically significant. Furthermore, no between-group differences were found in the time from diagnosis to resolution of nystagmus, or the time from symptom onset to resolution of nystagmus. Kaplan-Meier analysis of the time course of persistent geotropic DCPN resolution from the day of diagnosis and day of symptom onset revealed no significant differences between the groups. CONCLUSION Our findings indicate that mCuRM had no therapeutic benefit for a persistent geotropic DCPN and suggest that the pathophysiology of persistent geotropic DCPN is less likely to be a light debris attached to the cupula.

Abstract
Benign paroxysmal positional vertigo (BPPV) is the most common type of positional vertigo. A canalolithiasis-type of BPPV involving the lateral semicircular canal (LSCC) shows a characteristic direction-changing positional nystagmus (DCPN) which beats towards the lower ear (geotropic) on turning the head to either side in a supine position. Because geotropic DCPN in LSCC canalolithiasis is transient with a latency of a few seconds, the diagnosis can be challenging if geotropic DCPN is persistent without latency. The concept of “light cupula” has been introduced to explain persistent geotropic DCPN, although the mechanism behind it requires further elucidation. In this review, we describe the characteristics of the nystagmic pattern in light cupula and discuss the current evidence for possible mechanisms explaining the phenomenon.

Abstract
CONCLUSIONS Patients with BPPV comorbid with hypertension (h-BPPV) tend to receive a delayed diagnosis of BPPV. Comorbidity with hypertension did not influence the efficacy of the repositioning maneuver; however, comorbidity with hypertension was associated with an increased recurrence rate of BPPV. OBJECTIVES To determine the clinical characteristics and outcomes of h-BPPV, as well as the clinical differences between h-BPPV and idiopathic BPPV (i-BPPV). METHODS The authors reviewed the medical records of 41 consecutive patients with h-BPPV (the h-BPPV group) from March to December 2014 and 47 patients with i-BPPV (the i-BPPV group) during the same period. RESULTS There were no significant differences in age, sex ratio, or the affected side between the h-BPPV and i-BPPV groups. The proportion of patients reporting an initial episode of positional vertigo was significantly lower in the h-BPPV group (51.22% vs 74.47%; p = .024). Patients in the h-BPPV group reported a longer median episode duration than did those in the i-BPPV group (60 days vs 15 days; p = .017). The results of treatment using repositioning maneuvers were similar between the two groups. At follow-up, 13 patients in the h-BPPV group were diagnosed with recurrent BPPV compared with six in the i-BPPV group (p = .031).

Abstract
CONCLUSION Benign paroxysmal positional vertigo (BPPV) is strongly related to sleep. This study proposes a micro-otoconia accumulation theory in which the pathological debris is an aggregate of micro-otoconia over a long time period, and which begins to slide by its own weight during sleep. OBJECTIVES To examine the onset time of idiopathic BPPV and to investigate its etiology. METHOD Patients (n = 351) were classified as posterior canalolithiasis (PC), horizontal canalolithiasis (HC), and horizontal heavy cupula (HHC) according to nystagmus findings. This study examined the medical records, and categorized the onset times into the following four groups; (1) during sleep, (2) at the time of rising, (3) morning, and (4) afternoon. RESULTS PC (n = 135): In 33 patients, vertigo occurred during sleep, in 69 patients at rising, in 10 patients in the morning, and in 23 patients in the afternoon. HC (n = 87): In 38 patients, vertigo occurred during sleep, in 30 patients at rising, in eight patients in the morning, and in 11 patients in the afternoon. HHC (n = 129): In 27 patients, vertigo occurred during sleep, in 59 patients at rising, in 15 patients in the morning, and in 28 patients in the afternoon.

Abstract
Accurate lateralization is important to improve treatment outcomes in horizontal semicircular canal (HSCC) benign paroxysmal positional vertigo (BPPV). To determine the involved side in HSCC-BPPV, the intensity of nystagmus has been compared in a head-roll test (HRT) and the direction of nystagmus was evaluated in a bow and lean test (BLT). The aim of this study is to compare the results of a BLT with those of a HRT for lateralization of HSCC-canalolithiasis and cupulopathy (heavy cupula and light cupula), and evaluate treatment outcomes in patients with HSCC-canalolithiasis. We conducted retrospective case reviews in 66 patients with HSCC-canalolithiasis and 63 patients with HSCC-cupulopathy. The affected side was identified as the direction of bowing nystagmus on BLT in 55 % (36 of 66) of patients with canalolithiasis, which was concordant with the HRT result in 67 % (24 of 36) of cases (concordant group). Lateralization was determined by comparison of nystagmus intensity during HRT in 30 patients who did not show bowing or leaning nystagmus. The remission rate after the first treatment was 71 % (17 of 24) in the concordant group and 45 % (5 of 11) in the discordant group. Both bowing and leaning nystagmus were observed in all patients with cupulopathy, and the side of the null plane was identified as the affected side. In conclusion, bowing and/or leaning nystagmus were observed in only 55 % of patients with HSCC-canalolithiasis, and the first treatment based on the result of BLT alone was effective in only 45 % of the patients in whom the BLT and HRT were discordant, which may suggest that the usefulness of BLT in lateralizing the HSCC-canalolithiasis may be limited.

Abstract
Depending on the temporal course, three forms of vertigo syndrome can be differentiated: 1) vertigo attacks, e.g. benign paroxysmal positional vertigo (BPPV), Menière's disease and vestibular migraine, 2) acute spontaneous vertigo lasting for days, e.g. acute unilateral vestibulopathy, brainstem or cerebellar infarction and 3) symptoms lasting for months or years, e.g. bilateral vestibulopathy and functional vertigo. The specific therapy of the various syndromes is based on three principles: 1) physical treatment with liberatory maneuvers for BPPV and balance training for vestibular deficits, 2) pharmacotherapy, e.g. for acute unilateral vestibulopathy (corticosteroids) and Menière's disease (transtympanic administration of gentamicin or steroids and high-dose betahistine therapy); placebo-controlled pharmacotherapy studies are currently being carried out for acute unilateral vestibulopathy, vestibular paroxysmia, prophylaxis of BPPV, vestibular migraine, episodic ataxia type 2 and cerebellar ataxia; 3) psychotherapy for functional dizziness.

Abstract
OBJECTIVE To evaluate the short-term efficacy of computer-controlled and modified roll maneuver (CMRM) versus conventional roll maneuver (RM) for treatment of geotropic lateral canal benign paroxysmal positional vertigo (BPPV). STUDY DESIGN Prospective case-controlled study. SETTING Academic hospital. PATIENTS One hundred consecutive patients diagnosed as having unilateral idiopathic geotropic lateral canal BPPV with a duration of symptoms of less than 2 weeks. INTERVENTIONS Fifty-two patients (aged 32-80 yr; mean, 55.9 yr; 18 men and 34 women) were treated with CMRM that was composed of three sequential 360-degree rotations and 48 patients (aged 30-71 yr; mean, 52.4 yr; 20 men and 28 women) treated with RM that consisted of one 360-degree rotation. MAIN OUTCOME MEASURES Resolution of vertigo on the supine roll test at 48 hours after initial maneuver and the number of maneuvers required for final resolution of vertigo were main outcome measures to assess the efficacy of treatment. RESULTS On the supine roll test at 48-hour follow-up after initial maneuver, 44 (84.6%) of 52 CMRM-treated patients and 23 (54.2%) of 48 RM-treated patients had resolution of vertigo (p < 0.01). All patients obtained final resolution of vertigo with a maximum of five maneuvers in each group, but the CMRM group had less mean number of maneuvers required for final resolution of vertigo compared with the RM group (1.23 ± 0.39 versus 1.63 ± 0.68, p < 0.05). No significant adverse effects and complications occurred aside from two patients with conversion into posterior canal BPPV in each treatment. CONCLUSION The CMRM consisting of three sequential 360-degree rotations for geotropic lateral canal BPPV has a higher initial success rate compared with the conventional RM consisting of one 360-degree rotation.

Abstract
Acute dizziness/vertigo is among the most common causes for visiting the emergency department. The traditional approach to dizziness starts with categorizing dizziness into four types: vertigo, presyncope, disequilibrium, and nonspecific dizziness. However, a recently proposed approach begins with classifying dizziness/vertigo as acute prolonged spontaneous dizziness/vertigo, recurrent spontaneous dizziness/vertigo, recurrent positional vertigo, or chronic persistent dizziness and imbalance. Vestibular neuritis and stroke are key disorders causing acute prolonged spontaneous dizziness/vertigo, but the diagnosis of isolated vascular vertigo has increased by virtue of developments in clinical neurotology and neuroimaging. However, a well-organized bedside examination appears more sensitive than brain imaging in diagnosing strokes presenting with acute dizziness/vertigo. A detailed history is vital to diagnose recurrent spontaneous dizziness/vertigo since confirmatory diagnostic tests are usually unavailable. Isolated positional vertigo is usually caused by benign paroxysmal positional vertigo, which can be treated at the bedside. In recent years, marked progress has occurred in the evaluation/management of acute dizziness/vertigo. However, even with developments in imaging technology, the diagnosis of acute dizziness/vertigo largely relies on bedside examination.
