红外摄像眼震镜对良性阵发性位置性眼震的观察

良性阵发性位置性眩晕(benign paroxysmal positional veal-go，BPPV)作为最常见的外周性旋转性眩晕，其典型的病理改变是变性脱落的耳石坠入后半规管作用于壶腹嵴所致。而变位性试验是诊断BPPV的常规检查手段，变位性眼震的类型和方向对BPPV的定位诊断有重要意义。本文利用红外摄像眼震镜(videonystagmoscope，VNS)，在变位性眼震试验中对42例怀疑为BPPV患者进行实时检测，并在头位变位疗法中动态观察眼震变化，以评价VNS在BPPV的诊断和疗效观察方面的临床价值。

颅外伤引起位置性眩晕的神经耳科学观察

作者报告颅外伤后一周内出现阵发性位置性眩晕者有22例。变位试验均显示旋转型或有一强烈旋转相的眼震。由坐位改为垂头位时的眼震指向与垂头位改为坐位时的指向相反。但也有仅在一种变位时显示眼震者。除2例较轻外,一般有强烈的旋转性眩晕。多数患者仅有轻度呕吐,很少植物神经反应。神经学检查及CT扫描均无异常发现。中耳出血13例,颞     

“中枢型”位置性眼震是多发性硬化症的早期症状

位置性眼震系指当头处于某一位置时出现并在这一头位持续存在的眼震(Bárány,1913)。Cawthorne(1961)称这种眼震为中枢性位置性眼震,并指出其与颅后窝病变有关。本文报告4例多发性硬化症出现中枢型位置性眼震,3例证实病变在第四脑室,1例未肯定。 3名22～28岁的年青妇女,就诊前即有发作性眩晕及轻度恶心,仰卧和侧卧时加重。临床检查除不稳、睁眼位置性眼震外无其他发现;只要维持临界体位,眼震即持续,眩晕、恶心加重。其中一名病人首次犯病后五天发作频繁,二个月后症状和眼震消失,闭眼时可记录到右侧位位置

“Sitting-up vertigo as an expression of posterior semicircular canal heavy cupula and posterior semicircular canal short arm canalolithiasis”

BackgroundVestibular symptoms on sitting-up are frequent on patients seen by vestibular specialists. Recently, a benign paroxysmal positional vertigo (BPPV) variant which elicits vestibular symptoms with oculomotor evidence of posterior semicircular canal (P-SCC) cupula stimulation on sitting-up was described and named sitting-up vertigo BPPV. A periampullar restricted P-SCC canalolithiasis was proposed as a causal mechanism.ObjectiveTo describe new mechanisms of action for the sitting-up vertigo BPPV variant.MethodsEighteen patients with sitting-up vertigo BPPV were examined with a pre-established set of positional maneuvers and follow-up until they resolved their symptoms and clinical findings.ResultsAll patients showed up-beating torsional nystagmus (UBTN) and vestibular symptoms on coming up from either Dix-Hallpike (DHM) or straight head-hanging maneuver. Sixteen out of 18 patients presented a sustained UBTN with an ipsitorsional component to the tested side on half-Hallpike maneuver (HH). A slower persistent contratorsional down-beating nystagmus was found in eleven out 18 patients tested on nose down position (ND).ConclusionsPersistent direction changing positional nystagmus on HH and ND positions indicative of P-SCC heavy cupula was found in 11 patients. A sustained UBTN on HH with the absence of findings on ND, which is suggestive of the presence of P-SCC short arm canalolithiasis, was found on 5 patients. All patients were treated with canalith repositioning maneuvers without success, but they resolved their findings by means of Brandt-Daroff exercises. We propose P-SCC heavy cupula and P-SCC short arm canalolithiasis as two new putative mechanisms for the sitting-up vertigo BPPV variant.     

Posterior semicircular canal type benign paroxysmal positioning vertigo with ageotropic paroxysmal positioning nystagmus

We report on 3 patients with typical benign paroxysmal positioning vertigo (BPPV) and atypical, paroxysmal positioning nystagmus. When the Dix-Hallpike test was performed, the patients exhibited an ageotropic nystagmus, different from that classically described in posterior semicircular canal BPPV. It was torsional-vertical with the vertical component beating downwards, and the torsional component was beating away from the lowermost ear. In both left and right Dix-Hallpike positions, the upper poles of the eyes were turning away from the lowermost ear. The atypical ageotropic paroxysmal positional nystagmus of the posterior semicircular canal was observed in the evolution of the BPPV in 2 patients and on the first examination in the third. Two patients had changing patterns of paroxysmal positioning nystagmus.     

Treatment of benign positional vertigo using the semont maneuver: efficacy in patients presenting without nystagmus

OBJECTIVE: To evaluate and compare the efficacy of the Semont liberatory maneuver on "objective" benign paroxysmal positional vertigo (BPPV) defined as vertigo with geotropic nystagmus in Dix-Hallpike positioning versus "subjective" BPPV defined as vertigo without nystagmus in Dix-Hallpike positioning. STUDY DESIGN: Retrospective chart review. METHODS: One hundred sixty-two patients with positional vertigo during Dix- Hallpike positioning were identified. Patients were evaluated for the presence or absence of nystagmus. All patients underwent the Semont liberatory maneuver. The patient's condition at follow-up was documented at 3 weeks as complete, partial, or failure. Repeated procedures were performed if necessary. RESULTS: There were 127 cases of objective BPPV and 35 cases of subjective BPPV. Overall, 90% of all patients tested had significant improvement of their vertigo after 1.49 maneuvers on average. Improvement was seen in 91% of patients with objective BPPV after 1.59 maneuvers on average, compared with 86% in subjective BPPV after 1.13 maneuvers on average (chi2 test, not significant [P = .5]). Patients with a history of traumatic origin or cause had an overall success rate of 81% compared with 92% for nontraumatic causes or origins (chi2 test, not significant [P = .1]). Recurrences were seen in 29% of patients after a successful initial maneuver; however, 96% of these patients responded to further maneuvers. Four patients with persistent symptoms after conservative management underwent posterior semicircular canal occlusion with resolution of symptoms. CONCLUSION: The Semont liberatory maneuver provides relief of vertigo in patients with positional vertigo, even in patients without objective nystagmus.

Benign Paroxysmal Positional Vertigo without nystagmus: diagnosis and treatment

Nystagmus tests to diagnose BPPV are still relevant in the clinical evaluation of BPPV. However, in everyday practice, there are cases of vertigo caused by head movements, which do not follow this sign in the Dix-Hallpike maneuver and the turn test.AimTo characterize BPPV without nystagmus and treatment for it.Materials and methodsA non-systematic review of diagnosis and treatment of benign paroxysmal positional vertigo (BPPV) without nystagmus in the PubMed, SciELO, Cochrane, BIREME, LILACS and MEDLINE databases in the years between 2001 and 2009.ResultsWe found nine papers dealing with BPPV without nystagmus, whose diagnoses were based solely on clinical history and physical examination. The treatment of BPPV without nystagmus was made by Epley maneuvers, Sémont, modified releasing for posterior semicircular canal and Brandt-Daroff exercises.ConclusionFrom 50% to 97.1% of the patients with BPPV without nystagmus had symptom remission, while patients with BPPV with nystagmus with symptom remission ranged from 76% to 100%. These differences may not be significant, which points to the need for more studies on BPPV without nystagmus.     

Effectiveness of treatments for benign paroxysmal positional vertigo of the posterior canal.

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.     

耳石复位法治疗半规管良性阵发性位置性眩晕的临床研究

目的：评价耳石复位法治疗良性阵发性位置性眩晕（BPPV）疗效。方法：回顾分析2002年1月～2005年6月间治疗的230例BPPV患者的临床资料。根据半规管耳石假说,随机分成治疗组122例,对照组108例,分别接受耳石复位法和一般对症治疗。治疗结束后2周复查并评定疗效。结果：治疗组88例眩晕和眼震于治疗后立即或在2周内逐渐消失,18例改善,16例无效,治愈率72．1％,总有效率86．9％。对照组51例立即或在2周内逐渐消失,23例改善,34例无效,治愈率47．2％,总有效率68．5%。两组疗效相比差异有统计学意义。结论：鉴于耳石复位法治疗无明显禁忌证,方法简单,无痛苦和不良反应,一次性治疗疗效高,短期（1～3个月）随访无复发,因此认为该法可作为BPPV门诊治疗的首选方法。     

Cerebellar vermis lesions and tumours of the fourth ventricle in patients with positional and positioning vertigo and nystagmus

Positional and positioning vertigo and nystagmus syndromes are usually due to peripheral vestibular dysfunction. The most common form is benign paroxysmal positioning. In this paper, we discuss more serious aetiologies in the differential diagnosis for patients presenting with a history suggestive of benign paroxysmal positioning vertigo. We draw attention to the diagnosis of cerebellar vermis lesions and tumours of the fourth ventricle by presenting two cases of patients with positional nystagmus of so called benign paroxysmal type. We review the literature on positional nystagmus, highlighting key findings on history and physical examination to aid in the correct diagnosis of benign paroxysmal positioning vertigo, and to differentiate it from the rare yet sinister central aetiologies that can present with positional vertigo of the benign positional type. This is with the aim to avoid over-investigating a common presentation without missing a serious diagnosis.     

Diagnostic problems in patients with benign paroxysmal positional vertigo

The steps of the examination procedure applied for a correct diagnosis of benign paroxysmal positional vertigo (BPPV) are reviewed. A precise diagnosis is important in view of treatment of this type of vertigo by rehabilitation therapy. Clinical experience supports the concept that the diagnosis has to be based not only on a typical history, but also on the presence of a reproducible vertigo and paroxysmal positioning nystagmus. In the procedure applied in the department, this nystagmus can be reproduced by the Dix-Hallpike maneuver under Frenzel's glasses, during electronystagmography (ENG) recording in the position tests, or it can be present in the vestibular habituation training test battery (a battery of 19 maneuvers applied for defining the adequate exercises in the rehabilitation treatment for BPPV). Analysis of the reviewed data in 95 patients showed that one third of the patients described the vertigo in a rather atypical way, while the further testing revealed a typical BPPV. This experience denies any absolute reliability to only history. In fact, only the finding of such a paroxysmal positioning nystagmus is conclusive for confirming BPPV. However, also the presence of such a nystagmus appeared not to be a constant datum, so that in some patients more than one examination was necessary to come to a reliable diagnosis. It is obvious that, for detecting a paroxysmal positioning nystagmus, ENG is less reliable than the Dix-Hallpike maneuver under Frenzel's glasses.
