- Benign paroxysmal positional vertigo (BPPV) is the most common cause of
recurrent vestibular vertigo. The etiology of BPPV is unidentified in 50%?70%
of patients. However in secondary BPPV, the etiologies are well known a head
injury as an example. And it has been reported that even minor head trauma can
evoke BPPV. The authors experienced a case of bilateral BPPV occurred during
a dancing rehearsal in a school thereby we report the case with a review of the
related literatures.

- Objective: Benign paroxysmal positional vertigo (BPPV) is one of most common
peripheral vestibular disorders. The aim of this study was to identify recurrence
in the long-term follow-up of patients with BPPV after successful canalith
repositioning maneuvers, and to determine which factors contribute to recurrence.
Methods The authors reviewed the medical records of 202 consecutive patients
with BPPV during the period January 2002 to December 2004 and investigated
112 patients with BPPV treated over the same period. Finally, 71 patients were
enrolled in this study. The estimated risk of recurrence used a Kaplan-Meier
analysis. For long-term follow-up, patients were contacted by telephone for further
information by one experienced doctor.
Results A total of 71 patients with idiopathic BPPV fulfilled the inclusion criteria.
Forty-two patients had posterior semicircular canal-BPPV and 29 patients
lateral semicircular canal-BPPV. Recurrence rates in the posterior semicircular
canal-and lateral semicircular canal-BPPV were 24% (18/42) and 41% (12/29),
respectively (p>0.05). Recurrence following successful treatment during a longterm
follow-up period was 23 out of 30 patients within 1 year, 5 patients between
1 and 3 years, 1 patient at between 3 and 5 years, 1 patient after 5 years, respectively.
Conclusion The authors found no significant difference between the posterior
semicircular canal and lateral semicircular canal-BPPV regarding recurrence.
Recurrence mostly occurred within the first 3 years (93%) following successful
canalith repositioning procedure.

- et, and the characteristics of vertigo. Results: Median follow-up was 29 months (range, 27−37 months). Patients had a mean age at onset of 48.2 years and a mean duration of 2.75 years. An obvious female predilection was found, and unilateral caloric paresis (≥25%) was seen in 23.3%. Of the 30 patients, symptoms resolved in 80% but were unchanged in 20%. No patient with RV developed a central nervous system disease or benign paroxysmal positional vertigo during follow-up. Conclusion: The present study shows that in the majority of cases, vertigo resolved following diuretics medication. In cases of the patients with severe or disabling recurrent vestibulopathy, the diuretics medication may be effective in reducing the frequency of vertigo attacks.

Abstract

- Background and Objectives: It is suggested that some patients with benign paroxysmal vertigo of childhood (BPVC) go on to develop migraine. However, neither the natural course nor the clinical features of BPVC have been determined, and therefore, the aim of this study was to investigate the clinical characteristics and the natural course of BPVC. Materials and Methods: During the period January 2002 to December 2009, we reviewed the clinical records of 58 patients diagnosed with BPVC. All patients were approached by telephone and using a questionnaire. The clinical characteristics of vertigo, such as sex and age distribution, duration and frequency of vertigo, associated symptoms, development of migraine, and neurologic abnormalities, were analyzed. Results: Mean follow- up duration was 73.2 months (range, 31-119 months). Patients had a mean age at onset of 11.8 years and a mean duration of 6.1 years. An obvious female predilection was found, and 40% of BPVC developed to migraine had a family history of migraine. Of the 32 patients, symptoms resolved in 68.7% but were unchanged in five patients (15.6%). BPVC developed to migraine in five patients (15.6%). Conclusion: This study suggests that vertigo spontaneously resolves in the majority of cases. However, the incidence of development to migraine in the BPVC patients is higher than that in general population.

Abstract

- The threat of pandemic influenza has focused attention and resources on virus surveillance, prevention, and containment. The World Health Organization has strongly recommended the use of the antiviral drug, Oseltamivir (TamifluⓇ), to treat and prevent pandemic influenza infection. In recent years, there have been case reports of vestibulocochlear events during or after oseltamivir treatment, other countries. Oseltamivir is generally well-tolerated and its most frequent adverse effects include nausea and vomiting, diarrhea, and abdominal pain. Up to now, bilateral vestibular hypofunction after oseltamivir medication has not been reported. Herein, we report a very rare case of a 36-year-old female with bilateral vestibular hypofunction following oseltamivir medication.

Abstract

- Background and Objectives: The aim of this study was to examine the localizations of β1- and β2-adrenergic receptors (ARs) in rat vestibular nuclei by immunohistochemical staining procedure.
Materials and Methods: Twelve male Sprague- Dawley rats were used in this study. Primary antibodies for the β1- and β2-ARs were used. The sections were treated with a biotinylated goat anti-rabbit antibody. The sections were then incubated in avidin-biotin-peroxidase reagent and processed with immunoperoxidase using 3.3’-diaminobenzidine tetrahydrochloride.
Results: β1-AR and β2-AR immunopositive neurons were found to be distributed throughout the four major vestibular nuclei. Both receptors were primarily detected in neuronal somata and their proximal dendrites. β1-AR and β2-AR were moderately expressed in the superior vestibular nucleus, lateral vestibular nucleus, medial vestibular nucleus, and spinal vestibular nucleus.
Conclusion: The present study demonstrates, for the first time, that β1-AR and β2-AR receptors are localized in rat vestibular nuclei. Furthermore, this study may provide additional speculation into the role of ARs during vestibular signal processing. Further studies are needed to clarify the roles played by β1-ARs and β2-ARs through physiologic and functional studies.

Abstract
PDF
- Vestibular neuritis (VN) is characterized by the acute onset of vertigo, nausea and vomiting, in the absence of hearing loss or tinnitus. Cerebellar and brain stem infarction represents approximately 2.3% of acute strokes overall. Those can result from occlusion of the superior cerebellar artery, anterior inferior cerebellar artery, or the posterior inferior cerebellar artery. Central vertigo such as cerebellar or brain stem infarction may present with nonspecific symptoms similar to those of VN. Patients with isolated vertigo due to cerebral infarction may pose a significant diagnostic challenge to the neurotologists. It is know n for being frequently misdiagnosed, often with consequent disability. We report 2 cases of cerebral infarction mimicking VN initially with a review of the related literatures.

Abstract

- Serous or suppurative labyrinthitis is one of the intratemporal complications of acute or chronic otitis media. Labyrinthitis can occur by meningogenic or hematogenous infection. Major symptoms of labyrinthitis are vertigo and hearing loss. The disease progresses in two phases; serous labyrinthitis, so called toxic labyrinthitis, and suppurative labyrinthitis. If labyrinthitis treated at serous phase, hearing could be saved. But, if the disease progressed to suppurative phase, hearing loss is difficult to recover. Therefore it is very important to distinguish these two phases of labyrinthitis when treating the patient. In general, the direction of nystagmus during labyrinthitis is helpful sign to distinguish these two phases. We report here on an unusual case of acute serous labyrinthitis complicated with chronic otitis media showing atypical pattern with a review of the related literatures.

Abstract
PDF
- Background and Objectives The intimate relationship of vertigo and anxiety has been previously recognized. Anxiety may have an important influence on recovery of symptoms in vestibular neuritis (VN). The aim of study was to evaluate subjective anxiety of the pre-VN, at the time of onset of VN, and just after vestibular rehabilitation therapy (VRT) using Beck Anxiety Inventory (BAI) questionnaire, respectively.
Materials and Methods Twenty-eight patients with VN were asked to complete the BAI and dizziness handicap inventory (DHI). Each of the BAI and DHI was scored. We also evaluated the relationship between the DHI and BAI scores.
Results The VN patients at the time of attack had significantly more anxiety with vertigo and related symptoms (p<0.05). In most patients, anxiety level decreased following VRT. Conclusion These findings indicate that almost every VN patients can recovery from anxiety as vertigo regressed. However, the emotional support as well as physical and/or functional rehabilitation may be required to provide a more rapid and complete return to normal daily lives for these patients.

- Background and Objectives Vestibular neuritis (VN) is one of critical life events that can affect physical, emotional, and function aspects of quality of life. Most patients recover well from VN within 6 months following the onset of the disease. However, they can still interfere with their daily lives in some patient with VN. Dizziness Handicap Inventory (DHI) was developed to assess the self-perceived handicapping effects imposed by vestibular system diseases. The aim of study was to evaluate subjective symptoms among the pre-VN, at the time of onset of VN, and post-VN using DHI questionnaire, respectively.
Materials and Methods Twenty patients with VN were asked to complete the DHI by mailed survey. Each of the DHI was scored. We also evaluated the relationship between the DHI scores and degree of the canal paresis on the caloric test.
Results Almost every patients had substantially improved its subjective symptoms in 6 months after VN. There was no correlation between the canal paresis in the lesion ear and DHI scores at the time of VN.
Conclusion The results of this study suggest that most patients recovery well from VN without any handicap, but the emotional support in combination with physical and/or functional rehabilitation should be required to provide early resumption of normal activity.

Abstract

- Herpes zoster oticus (HZO) is characterized by auricular vesicles, facial palsy and vestibulocochlear dysfunction. The 8th cranial nerve can be most frequently involved. Rarely, it may be associated with the involvement of 5th, 6th, 9th, 11th or 12th cranial nerve. However, only few cases of HZO involving vestibular nerve without facial nerve palsy have been previously reported. We experienced an unusual case of 38-year-old woman who presented with auricular vesicles, otalgia, and vertigo of whilrling nature but not with facial palsy. Vestibular evoked myogenic potential (VEMP) and caloric tests that were performed to determine which division of vestibular nerve was involved demonstrated that decreased responses in this case. We report a case of HZO involving superior and inferior vestibular nerve without facial palsy that was confirmed by VEMP and caloric tests with a review of literature.
