Herpes zoster oticus (Ramsay Hunt syndrome) is characterized by facial nerve paralysis associated with vesticular eruptions and cochleovestibular symptoms. Many evidences have supported that it is caused by the reactivation of latent varicella-zoster virus in the geniculate ganglion. Recently we experienced a case 49-year-old man presented severe vertigo and a vesicular eruptions of auricle and external ear canal. It is an unusual variant of herpes zoster oticus that involves only vestibular nerve without facial nerve palsy and hearing loss. We believe this case results from reactivation of latent varicella zoster virus in the vestibular ganglion and report with a review of literatures.

PURPOSE: This study was designed to evaluate diagnostic accuracy of serial electrocardiograms(ECG), myocardial band of creatinine phosphokinase(CK)(CK-MB/CK ratio) and two dimensional echocardiography(ECHO) for myocardial injury in patients with blunt chest trauma. METHODS: We prospectively investigated 54 patients(male : 38, female : 16, mean age : 41) with severe blunt chest trauma. Presence of myocardial injury was determined by increase(>0.1ug/L) of peak serum troponin T(TnT) concentration from serial mesurements. RESULTS: Among 54 patients with blunt chest trauma, 23 patients(43%) had increased peak TnT level which suggested of myocardial injury. Among 23 patients with increased TnT, abnormal ECG findings were found in 18(78%) and echocardiographic abnormalities were observed in 17(74%). Cardiovascular events in 9(39%) of 23 patients with increase Tnt. There was no cardiovascular events in patients with normal TnT. CONCLUSION: Significant proprotion of patients with blunt chest trauma had elevated TnT value which suggested of myocardial injury. We recommend echocardiagraphy and serial tracing of ECG to verify the clinical significance of elevated TnT in patients with blunt chest trauma.

Intrinsic cellular defenses are non-specific antiviral activities by recognizing pathogen-associated molecular patterns (PAMPs). Toll-like receptors (TLRs), one of the pathogen recognize receptor (PRR), sense various microbial ligands. Especially, TLR2, TLR3, TLR4, TLR7, TLR8 and TLR9 recognize viral ligands such as glycoprotein, single- or double-stranded RNA and CpG nucleotides. The binding of viral ligands to TLRs transmits its signal to Toll/interleukin-1 receptor (TIR) to activate transcription factors via signal transduction pathway. Through activation of transcription factors, such as interferon regulatory factor-3, 5, and 7 (IRF-3, 5, 7) or nuclear factor-kappaB (NF-kappaB), type I interferons are induced, and antiviral proteins such as myxovirus-resistance protein (Mx) GTPase, RNA-dependent Protein Kinase (PKR), ribonuclease L (RNase L), Oligo-adenylate Synthetase (OAS) and Interferon Stimulated Gene (ISG) are further expressed. These antiviral proteins play an important role of antiviral resistancy against several viral pathogens in infected cells and further activate innate immune responses.

1795 patients who visited orthodontic department from 1979 to 1987, were surveyed on the yearly tendency of patient distribution and state of Angle's classification. The results were as follows; 1. There was increased visiting rate of patient per year and higher visiting rate in female than in male. 2. 8-15 age group was 70.3% in total visiting patients and over 20 age group was 10.8%, under 7 age group was 7.3%. 3. Class I malocclusion was 26.3%, Class II div 1 was 31.0%, Class II div 2 was 1.6% and Class III was 41.1% in total visiting patient. 4. There was increased tendency to be received preventive treatment than fixed treatment and increased extracting rate per year in fixed treatment. 5. There was increased tendency for the number of the patient to be received orthognathic surgery.

Background and Objectives: To examine the maturational status of the auditory cortex in adults with cochlear implants (CIs) using the latencies of the P1, N1, and P2 components of cortical auditory-evoked potentials (CAEPs). Subjects and Methods: A total of 25 adults with CIs and 25 age-matched, normal-hearing control subjects participated in this study. Specifically, patients with CIs were divided into three groups depending on their age of deafness onset: Group A comprised patients with prelingual deafness who had received CI during early childhood (n=7), Group B comprised patients with early childhood-onset, progressive deafness who had received CI during childhood (n=6), and Group C comprised patients with adult-onset deafness (n=12). The P1, N1, and P2 latencies of their CAEPs were then compared between CI patients and normal-hearing subjects. Results: All participants showed clear CAEP responses. P1 and N1 latencies in Group A and Group C patients were significantly longer than those in the control group. Meanwhile, Group B patients had significantly longer N1 and P2 latencies, as compared with those in the control group. Conclusions Patients with prelingual deafness and those with early-childhood onset, progressive deafness who received CI developed primary and higher-order auditory areas postoperatively when they became adults. However, their auditory cortex maturational statuses seemed to be worse than that of normal-hearing individuals. Furthermore, adult patients with late-onset deafness might experience degenerative auditory cortex changes during the auditory deprivation period between deafness onset and cochlear implantation.

BACKGROUND AND OBJECTIVES: This study aims to investigate the development of open-set speech perception abilities in children who received cochlear implantation at older age and to examine the preoperative variables contributing to the postoperative speech perception outcomes. SUBJECTS AND METHOD: Open-set speech perception abilities were assessed with the Monosyllabic Word and Common Phrases Tests for 37 prelingually deafened children who received implantation between the ages of 7 and 17 years. Their performance was compared to that of 60 children who received implantation before 7 years of age. To identify the factors contributing to the postoperative open-set speech perception abilities, we analyzed age at hearing aid fitting, age at implantation, duration of implant use, preoperative language and speech perception abilities, and pure tone thresholds in the better ear. RESULTS: The children who received implantation after 7 years of age significantly improved during the first year of implant use, but reached a plateau by 1.5 to 2 years after implantation, reaching scores between 60% and 70%. Children who received implantation after age 7 showed higher speech perception scores than the younger children over the first year of implant use, but showed lower scores than the younger children after 2-3 years of implant use. The variables associated with the postoperative open-set speech perception abilities were speech perception ability, language ability, and hearing levels before implantation. CONCLUSION: Prelingually deafened children who received implantation at older age can obtain substantial open-set speech perception understanding, but tended to reach a plateau between 1.5-2 years after implantation. Speech perception, language abilities, and hearing level before implantation contribute to the outcome.

BACKGROUND: Automated external defibrillator(AED) represent a major breakdown to permit more widespread application of the principle of early defibrillation. Many recent efforts to improve emergency medical services(EMS) and increase survival rates are simply efforts to get defibrillation to patients as rapidly as possible. AED is major innovation for the prehospital care of ventricular fibrillation cardiac arrest patients. The purpose of this study is to evaluate the course of initial training to three different groups(nurses, firefighters, and EMT trainee) to use AED. METHOD: We studies the efficacy of education of AED to 33 nurses, 15 EMT trainee, and 16 firefighters. Training lasted 75 mins and included 45 mins an overview of defibrillation, protocols for using the AED, and operation of the AED(Laerdal Heartstart 3000),15 mins demonstraion.4 check list was used to grade the performance of cardiopulmonary resuscitation, operation of the AED, and the time required to deliver the first three defibrillations. RESULT: There were no statistically significant differences in performance and time required to deliver an electrical countershock among the groups(p=0.4). To the second test 92fo of all group completed all steps successfully. The step most often foiled was the preparing of the AED for defibrillation. CONCLUSION: In nurses, EMT trainee, and firefighters, it is both feasible and effective to train AED use irrespective of the degree of the trainee.

Spontaneous cerebrospinal fluid (CSF) otorrhea is defined as CSF otorrhea where there are no identifiable causes including previous trauma, surgery, infection, neoplasm or congenital anomaly. The condition is rare. The origin of CSF leak is commonly a defect in the tegmen of the middle cranial fossa. The pathophysiology of spontaneous CSF otorrhea is unclear. Two theories of the etiology of bony defects of the temporal bone are the congenital bony defect theory and arachnoid granulation theory. The authors experienced a case of a 49-year-old female patient admitted with the complaint of persistent right ear fullness. Computed tomography revealed a large defect of the middle fossa and suspicious CSF otorrhea through the defect of tegmen tympani. Repair was successful with multiple bone chips using the transmastoid approach. The postoperative course was good and there has been no recurrence of the CSF leakage.
