Infectious mononucleosis, a comon systemic illnes primarily involving children and young adults, is due aparently to the Epstein-Bar virus (EBV). Although neurologic complications of infectious mononucleosis are rare, these include meningoen-cephalitis, Guillain-Barre syndrome and mononeuritis, and facial nerve paralysis. Bilateral facial nerve palsy rarely develops in patients with a primary Ebstein-Barr virus (EBV) infection, and only a few of these have clinical manifestations of infectious osis.

Canalith repositioning procedure (CRP) provides rapid and long-lasting relief of symptoms in most patients with benign paroxysmal positional vertigo (BPPV). However, some patients express nonspecific symptoms such as anxiety or discomfort after CRP, even after the disappearance of nystagmus and vertigo. The purpose of this study is to assess the residual symptoms after CRP in patients with BPPV using questionnaire. Subjects and Method:CRP was performed in 135 patients until nystagmus and vertigo disappeared, and the patients were asked to complete the Dizziness Handicap Inventory (DHI) before and five to seven days after treatment. For the control group, 135 normal volunteers were selected, and cross matched according to the age and sex with the patient group. The DHI were compared among pre CRP, post CRP and control group. Results: There were statistically significant differences between the pre-CRP and post-CRP DHI scores and also between the post-CRP and control group. Comparison between the pre and post-CRP DHI scores, and post-CRP and control group both showed incomplete improvement with respect to some items. Conclusion:Even after the successful CRP, DHI scores indicated incomplete recovery and residual subjective symptoms was presented. Thus, additional follow up and management may be needed.

Central vertigo of cerebellar origin may present the syndromes similar to those of peripheral vertigo such as vestibular neuronitis. The character of those vertigo syndrome depend on the location, extent, and the etiology of the lesion such as stroke, inflammation, mass. Cavernous hemangioma may be clinically silent, but can cause variable neurologic manifestations including central vertigo if it affects the vestibular system. We report a rare case of cerebellar cavernous hemangioma with the vertigo syndrome closely mimicked vestibular neuronitis.

Vestibular neuritis presents as a sudden onset of rotary vertigo with associated nausea, vomiting, and generalized imbalance. In general, the dizziness lasts from a few hours to several days with gradual, definite improvement throughout the course. Vestibular neuritis is now considered to be the more accurate term for cases that do not involve hearing loss. The diagnosis of vestibular neuritis depends on the history of spontaneous, prolonged vertigo, physical findings that are consistent with a unilateral peripheral vestibular paralysis, and the absence of other neurological symptoms and signs. History and physical examination alone are usually adequate for diagnosis, although one must ensure that a central insult is not at fault. Relevant differential diagnoses are pseudo-vestibular neuritis due to acute pontomedullary brainstem lesions or cerebellar nodular infarctions, vestibular migraine, sudden sensorineural hearing loss accompanies vertigo with a vestibular neuritis-like pattern and monosymptomatically beginning Meniere's disease. Vestibular function tests including caloric test, vestibular evoked myogenic potential are useful to identify the side of involvement and to localize the pathology to the inferior or superior vestibular nerve.

Congenital midle ear cholesteatoma is a keratinizing squamous epithelial cyst that classically presents as a white pearl in nital cholesteatoma depend upon the initial site of the disease. The most comon presentation of this disease is a conductive hearing los or a facial palsy of gradual onset. Other presentations include incapacitating vertigo with nystagmus, a feeling of fullnes in the ear, frequent otalgia, an abnormal eardrum noted at physical examination for an unrelated condition and meningitis. Recently, we experienced a case of congenital cholesteatoma that was presented as a post-auricular fistula. In considering the

Vertigo can be defined as an illusion or hallucination of movement. Vertigo can be caused by many different pathologies, some of which are potentially life threatening. The differential diagnosis of vertigo includes peripheral vestibular causes (i.e., those originating in the peripheral nervous system), central vestibular causes (i.e., those originating in the central nervous system), and other conditions. Benign paroxysmal positional vertigo, acute vestibular neuritis, and Ménière’s disease cause most cases of vertigo; however, the physicians who see the vertigo patients must consider other various causes including cerebrovascular disease, migraine, psychological disease, perilymphatic fistulas, multiple sclerosis, and intracranial neoplasms. History is the most important part of the assessment. Key questions should be asked and it is vital to establish if the patient is suffering from vertigo or some other complaint such as anxiety or syncope. History alone reveals the diagnosis in roughly three out of four patients complaining of dizziness, although the proportion in patients specifically complaining of vertigo is unknown. When collecting a patient’s history, the physician first must determine whether the patient truly has vertigo versus another type of dizziness. Once it is determined that a patient has vertigo, the next task is to determine whether the patient has a peripheral or central cause of vertigo. Key information from the history includes the timing and duration of the vertigo, what provokes or aggravates it, and whether any associated symptoms exist, especially neurologic symptoms and hearing loss. Other important clues to the diagnosis of vertigo may come from the patient’s medical history, including medications, trauma, or exposure to toxins. A neurological and otological examination should be performed, appropriate to the history. Associated neurologic signs and symptoms, such as nystagmus that does not lessen when the patient focuses, point to central (and often more serious) causes of vertigo, which require further work-up with selected laboratory and radiologic studies such as magnetic resonance imaging. Because patients with dizziness often have difficulty describing their symptoms, determining the cause can be challenging. An evidence-based approach using knowledge of key historic, physical examination, and radiologic findings for the causes of vertigo can help physicians establish a diagnosis and consider appropriate treatments in vertigo patients.

Background and Objectives : It has been shown that the epilaryngeal tube in the human airway is responsible for vocal ring, or the singer's formant. In previous study, authors showed that in trained tenors, besides the conventional singer's formant in the region of ,5500Hz, another energy peak was observed in the region of 8,000Hz. This peak was interpreted as the second resonance of the epilarynx tube. Singers in other voice categories who produce vocal ring are assumed to have the same peak, but no measurements have as yet been made. Materials and Methods : Fifteen tenors, fourteen baritones, seven sopranos and five mezzo sopranos attending the music college, department of vocal music who could reliably produce the head and chest registers were chosen for this study. Each subject was asked to produce an/ah/sound for at least three seconds for the head register sound(tenors ; G4, barions ; E4 sopranos ; F5 and mezzosopranos ; C5) and for the chest register sound (tenors ; C3, baritones ; D3, sopranos ; D4 and Mezzosoprano ; A3). The sound data was analyzed using the Fast Fourier Transform (FFT)-based power spectrum, Long term average(LTA) power spectrum using the FFT algorithm of the Computerized Speech Lab (CSL, Kay elemetrics, Model 4300B, USA). Statistical analysis was performed using the Mann-Whitney test of the Statistical Package for Social sciences(SPSS). Results : For head register sounds, a significant increase was seen in the 2,200-3,400Hz region(p<0.05) and the Similar to the head register sounds, there was a significant increase in energy in the four trained singer group compared with the untrained group in the 2,200-3,100Hz region(p<0.05), the 7,800-8,400Hz region(p<0.05) for the chest register sounds. Conclusions : When good vocal production was made for the head and chest registers, an energy peak was observed near 2,500Hz, a frequency already known as the "singer's formant', in all subjects in the study group. Another region of increased energy was observed around 8,000Hz that had not been noticed previously. The authors believe this region to be the second singer's formant.

Otosclerosis is a primary metabolic bone disease of the otic capsule and ossicles. It is one of the causes of acquired hearing loss, h the cause of otosclerosis is undetermined, the disease has a well established hereditary predisposition, with approximately half of all affected individuals having family members known to be affected. Many genetic studies of otosclerosis support an autosomal dominant mode of inheritance with penetrance in the range of 20- 40%. There have been a few reports of the clinically suspicious otosclerosis cases in Korea, bu cle-rosis. (Korean J Otolaryngol 2007 ;50 :182-5)
