Horizontal canal benign paroxysmal positional vertigo (HC-BPPV) can be classified as either the geotropic or apogeotropic subtype by the pattern of nystagmus triggered by supine head roll test. Most studies have reported the geotropic subtype as a more common pathophysiology in HC-BPPV than the apogeotropic subtype. According to the BPPV clinical practice guideline provided by the American Academy of Otolaryngology-Head and Neck Surgery and American Academy of Neurology in 2008, variations of the roll maneuver (Lempert maneuver of barbecue roll maneuver) are the most widely published treatments for HC-BPPV. In addition, various treatment techniques including Gufoni maneuver, Vannuchi-Asprella liberatory maneuver and forced prolonged positioning have been applied for HC-BPPV. However, the guideline failed to provide specific treatment guidelines for HC-BPPV based on evidence-based researches since only Class IV data on HC-BPPV treatment were available at the point of 2008 when the BPPV clinical practice guideline was published. This review article focused on the evidences of the efficacy of various maneuvers in the treatment of HC-BPPV published after the BPPV clinical practice guidelines of 2008.

Acute peripheral vestibulopathy, of which the chief complaint is positional vertigo, comprises benign paroxysmal positional vertigo (BPPV), labyrinthitis, labyrinthine fistula, and cerebellopontine angle tumors. Since the typical presentation of labyrinthine fistulas may be sensorineural hearing loss, positional vertigo, or disequilibrium, it is often difficult to distinguish from BPPV or Meniere's disease. Herein we report a 61-year-old female patient with typical symptoms and signs attributable to geotropic type variant of the lateral semicircular canal BPPV on the left side, who eventually was confirmed as having a labyrinthine fistula from chronic otitis media with cholesteatoma on the left side. This is another case where, even in the presence of isolated vertigo showing typical findings of acute peripheral vestibulopathy, other otologic symptoms and signs must not be overlooked.

Pseudo-vestibular neuritis is a central pathology of acute vestibular syndrome, characterized by unidirectional nystagmus mimicking acute peripheral vestibulophaty. We report a 39-year-old female patient who developed cerebellar infarction with isolated vertigo, spontaneous nystagmus, a positive head thrust test, and unilateral canal paresis in the contralesional side. The patient had no vascular risk factors. A diffusion-weighted image of the brain showed infarction of medial branch of posterior inferior and superior cerebellar artery on the left side. A magnetic resonance angiography of neck disclosed a wide range of diffused severe stenosis and narrowing of right and left vertebral arteries, respectively. This case suggests the possibility of vestibular ischemia masking the central pathology in isolated vertigo.

PURPOSE: In this study, we examined the difference in the treatment efficacy depending on the sympathetic activity in men with lower urinary tract symptoms (LUTS). METHODS: In the current single-center, retrospective study, we evaluated a total of 66 male patients aged 40-70 years of age, presenting with LUTS, whose International Prostate Symptom Score (IPSS) exceeded 8 points. They had a past 3-month history of taking alfuzosin XL, and their heart rate variability (HRV) was measured before and after the treatment. In addition, we also recruited 39 healthy volunteers who visited a health promotion center for a regular medical check-up. They were aged between 40 and 70 years and had an IPSS of <8 points. We divided the patients with LUTS into two groups: the groups A and B, based on a low frequency/high frequency (LF/HF) ratio of 1.7, which was the mean value of the LF/HF ratio in the healthy volunteers. After a 3-month treatment with alfuzosin XL, we compared treatment outcomes, based on the IPSS and peak urine flow rate, between the two groups. RESULTS: A 3-month treatment with alfuzosin XL, comprising the measurement of the HRV, was performed for the 23 patients of the group A (23/38) and 17 of the group B (17/28). After a 3-month treatment with alfuzosin XL, total IPSS and IPSS questionnaire 2 and 5 were significantly lower in the group A as compared with the group B. But this was not seen in the group B. Furthermore, there were no significant differences in other parameters, such as maximal flow rate and IPSS storage subscore, between the two groups. CONCLUSIONS: Our results indicate that the treatment efficacy was lower in patients with sympathetic hyperactivity as compared with those with sympathetic hypoactivity. Thus, our results will provide a basis for further studies to clarify causes of LUTS in a clinical setting.

Sudden sensorineural hearing loss (SNHL) due to blunt head trauma is a rare condition. Possible causes of SNHL by head trauma include cellular injury, perilymphatic fistula, labyrinthine concussion due to microfracture in inner ear and blunt trauma with simultaneous acute labyrithitis. We report here on two unusual cases in which cochleovestibular functions were totally damaged in patients with sudden SNHL due to blunt head trauma. Both cases presented with vertigo, tinnitus and a sudden onset of hearing impairment in the unilateral ear after blunt trauma. Audiograms revealed a profound to severe unilateral SNHL. Caloric testing revealed a decreased caloric response of 100% in the ipsilateral side compared to the contralateral side. Vestibular evoked myogenic potential testing revealed no response in the ipsilateral ear. Neither patient recovered hearing despite oral and/or intratympanic steroid therapy.

Usually, large amount of acute subdural hematoma needs prompt surgical removal. We report a case of rapid spontaneous resolution in a day. A 78-old female was admitted in comatose state after falling off from a bus. Initial brain CT scan revealed large amount of acute subdural hematoma that was completely resolved on follow-up brain CT taken 26hours after craniocerebral trauma. The spontaneous resolution needs redistribution of hematoma and dilution by CSF. The low density space between inner skull table and hematoma may suggest the possibility of spontaneous resolution.

OBJECTIVES: To investigate the vestibular evoked myogenic potentials (VEMP) results in benign paroxysmal positional vertigo (BPPV) patients and to verify its clinical applications in BPPV. SUBJECTS AND METHODS: Forty-one patients with diagnosis of BPPV and 92 healthy volunteers who underwent VEMP testing. Patients were treated by canalith repositioning maneuvers according to the affected canal, and testing of VEMP was performed at diagnosis and after treatment. RESULTS: VEMP results of BPPV patients showed prolonged p13 and n23 latencies compared with those of the control group, and we could not find any significant difference in VEMP latencies between patients with posterior and horizontal canal type of BPPV. The number of times that the maneuver was repeated did not correlate with the degree of latency prolongation, but in the "no response" group, the number of times was considerably greater than those in the "response" group. CONCLUSIONS: We found that VEMP latencies are increased in BPPV patients, which may signify neuronal degenerative changes in the macula of the saccule. When an extensive neuronal damage was suspected by VEMP results such as "no response" in VEMP, the disease progress showed a chronic and resistive course. Therefore, we propose that VEMP could be a useful method to determine a clinical prognosis of patients with BPPV.

Lymphangioma is a congenital malformation of the lymphatic system that easily expands into surrounding tissue similar to malignancies. Surgical excision has been the treatment of choice, but the results of surgical resection have been unsatisfactory due to incomplete resection, fluid collection and recurrence after surgery. Intralesional injection of OK-432(lyophilized incubation mixture of group A. streptococcus pyogenes of human origin) was employed in treating 24 patients with lymphangiomas between 1992 and 1997. The therapy was used as a primary therapy in 21 patients. Also it used in 3 patients with unresectable or recurrent lymphangioma. The results of intralesional injection of OK-432 were excellent in 8 patients (33.3%), good in 7 patients (21.8%) and poor in 7 patients (21.8%). The side effects were fever under 39.0degrees C and a local inflammation, however, were subsided in a few days without serious complications. These data suggest that intralesional injection of OK-432 is safe and effective for lymphangioma as a primary therapy and unresectable or recurrent lymphangioma as a secondary therapy.
