목 적: 본 연구에서는 외이도 및 중이에 생긴 편평상피암의 치료에 있어서 방사선치료의 역할에 대해 알아보고자 한다. 대상 및 방법: 1981년부터 2007년까지 외이도 및 중이에 생긴 편평상피암으로 치료 받은 총 35명의 기록을 후향적으로 분석하였다. 13명은 방사선치료 단독, 4명은 수술 단독, 18명은 수술 방사선 병용 요법으로 치료하였다. 방사선치료 단독군에서 조사된 중앙 방사선량은 66 Gy (범위, 39~70 Gy)이었고, 수술 방사선 병용 치료군에서는 61.2 Gy (범위, 44~70 Gy)를 조사하였다. 치료 방법에 따른 질병특이생존율 및 무국소진행생존율을 비교하였으며 추적관찰기간은 0.2~14.6년(중앙값 2.8년)이었다. 결 과: 3년 질병특이생존율 및 무국소진행생존율은 각각 80%, 63%이었다. 질병특이생존율에 관한 단변량 분석에서 전신수행상태 및 잔여 종양의 유무가 통계적인 유의성을 보여주었고, 무국소진행생존율에는 전신수행상태 및 조직학적 등급이 유의하였다. 치료 후 잔여 종양은 방사선 단독 치료군(69%)에서 수술 방사선 병용 치료군(28%)에 비해 많이 관찰 되었다. 비록 양군간에 질병특이생존율은 통계학적인 차이를 보이지 않았지만 방사선 단독 치료군에서 병용 치료군에 비해 조기 국소 재발의 빈도가 높았다. 결 론: 외이도 및 중이의 편평상피암 환자에서 방사선 단독 치료는 질병특이생존율에 있어서 수술 방사선 병용 치료와 유사한 결과를 보여주었다. 그러나 낮은 국소 제어율을 높이기 위한 치료 방법의 향상이 있어야 할 것으로 생각된다.

Benign paroxysmal positional vertigo (BPPV) is one of the most common clinical entities encountered in a dizziness clinic. Treatment of this disease, canalith repositioning procedures, have been reported to be successful in 44-90%. Treatment requires only one treatment visit in most patients. However, there are significant numbers of patients who require multiple treatment visits for relief. The goal of this study is to identify variables that may be associated with these difficult to treat cases. Retrospective review was performed for the patients diagnosed as BPPV at St. Carollo dizziness center. Variables for statistical analysis included age, sex, involved canal, presence of bilateral disease, presence of recent head trauma, presence of chronic otitis media, history of middle ear surgery, history of otologic surgery, unilateral vestibular loss, underlying disease such as hypertension or diabetes, change of involved canal during treatment course and number of treatment visits. Two hundred patients with BPPV who received treatment were identified from JAN. 2006 to JUN. 2007. 87% required one treatment visit, 5% required second treatment visit, and 95% were successfully treated after three treatment visits. Variables such as bilateral disease, post-traumatic BPPV, duration of symptom before treatment and change of involved canal during treatment were significantly related with number of treatments. Patient's with bilateral BPPV or with recent head trauma or longer duration of symptom are more likely to require multiple visits for canalith repositioning.

Granulomatosis with polyangiitis (GPA) and Immunoglobulin (Ig) $G_4$-related disease ($IgG_4$-RD) are rare diseases and early diagnosis and proper management are imperative to prevent multi-organ damage. The authors present a case of a 60 years old woman who had facial paralysis and hearing loss. Lt intact canal wall tympanomastoidectomy, Lt facial nerve decompression and ossiculoplasty with partial ossicular replacement prosthesis (PORP) was done. During operation, middle ear tissue was biopsied and GPA with $IgG_4$-RD was diagnosed. After methyl prednisolone (MPD) pulse therapy and azathioprine therapy, the severity of paralysis was improved. We present this case because common otologic symptoms like facial palsy and hearing loss could be initial symptoms of rare systemic disease.

Chronic otitis media (COM) is a chronic inflammatory disease which affects the middle ear, mastoid cavity. It presents hearing loss, ear pain, dizziness, headache, temporomandibular joint (TMJ) inflammation and intracranial complication. Intracranial complications such as skull base osteomyelitis (SBO) may occur secondary to COM due to transmission of infection by a number of possible routes. SBO is an uncommon condition with a significant morbidity and mortality if not treated in the early stages. We report a-67-year-old male patient with diabetes and untreated COM who presented atypical severe TMJ, periorbital and postmandibular pain. By computerized tomography (CT), magnetic resonance imaging (MRI) and whole body bone scan (WBBS), he was diagnosed with SBO spreading from untreated COM via infective arthritis of TMJ. Through this case, we suggest proper utilization of diagnostic imaging, especially CT or MRI for the early detection of SBO in the case of COM accompanying with the greater risk of infection developments such as diabetes.

A new neurological mutant has been found in the ICR outbred strain mouse. Affected mice display profound deafness and a head-tossing and bidirectional circling behavior, showing an autosomal recessive mode of inheritance. It was, therefore, named cir/Kr with the gene symbol cir. The auditory tests identified clearly the hearing loss of the cir mice when compared to wild type mice. Pathological studies confirmed the developmental defects in the middle ear, cochlea, cochlear nerve, and semicircular canal areas, which were correlated to the abnormal behavior observed in the cir mice. Thus, cir mice may be useful as a model for studying inner ear abnormalities and deafness. We have constructed a genetic linkage map by positioning 14 microsatellite markers across the (cir) region and intraspecific backcross between cir and C57BL/6J mice. The cir mouse harbors an autosomal recessive mutation on mouse chromosome 9. The cir gene was mapped to a region between D9Mit116 and D9Mit38 Estimated distances between cir and D9Mit116, and between cir and D9Mit38 are 0.7 and 0.2 cM, respectively. The gene in order was defines : centromere-D9Mit182-D9Mit51/D9Mit79/D9Mit310-D9Mit212/D9Mit184-D9Mit116-cir-D9Mit38-D9Mit20-D9Mit243-D9Mit16-D9Mit55/D9Mit125-D9Mit281. The mouse map location of the cir locus appears to be in a region homologous to human 3q21. Our present date suggest that the nearest flanking marker D9Mit38 provides a useful anchor for the isolation of the cir gene in a yeast artificial chromosome contig.

A 25-month-old boy was referred to the hospital due to large head detected on routine physical examination. At visit, dysmorphic facial appearances, including broad nose, prominent forehead, and coarse face, were noted. Nasal obstruction with nasal voice, prominent adenoids, and bilateral middle ear effusions were detected. His abdomen was distended, and liver and spleen were palpated about 3 finger and 2 finger breadths, respectively. He was operated for bilateral inguinal hernias. The motion of both elbow joints was mildly limited on supination and pronation. Urinary level of glycosaminoglycan was elevated and the enzyme activity of iduronate sulfatase in leukocytes was decreased. The mutational analysis of the gene iduronate 2-sulfatase (IDS) revealed c.263G>A (p.Arg88His) mutation. His developmental scale showed delayed development and there was cardiac valvular involvement (tricuspid regurgitation and mitral valve prolapse). After the diagnosis of Hunter syndrome, enzyme replacement therapy started on a weekly basis without progression of any clinical features. Here we report a case of early diagnosed Hunter syndrome detected by large head on routine examination. Thus, it is important to associate Hunter syndrome in the patient with large head especially, if there is the history of bilateral inguinal hernia and prominent adenoids to increase the possibility of early diagnosis and treatment.

During the past 14years 267 patients presented with a lump in the neck proven to be metastatic cancer histologically. In most cases the primary site was discovered by thorough physical examination, E.U.A.(examination under anesthesia) and radiodiagnostic studies. However in 31 cases complete diagnostic evaluation failed to reveal the primary site. This paper discusses the characteristics of this group of patients in terms of the frequency of the ultimately discovered primary sites, policies for diagnosis, methods of management, and the ultimate prognosis for such cases in Korea. The male: female ratio was 6.8:1 and 84 % of all cases occurred in the $51{\sim)70$ age group. The majority of these cancers were epidermoid carcinomas(67.7%) and 22 of the 31(71 %) were Stage IV lesinos(17 N3A lesions and 5 N3B lesions). Surgical management was employed in 7 cases only, and in 5 cases this was combined with rediotherapy, chemotherapy, or both. Nevertheless, the only patients who survived disease-free for two years or more (one for over 5 years) were two patients in this management group. None of the patients treated by radiotherapy or chemotherapy of a combination of these two modalities survived. Occult primary sites were eventually discovered in 5 of the 31 cases, two in the nasopharynx, and one each in the base of tongue, pyrifrom sinus, middle ear. Of the 21 cases with epidermoid carcinoma which presented in the neck, 2 are free of disease for 3years or more. Of those who underwent radical surgery two of five survived. This study thus confirms the principle enunciated by MacComb in 1972 that surgical treatment in the form of radical neck dissection is the cornerstone of management whenever feasible.

Noise may cause damage of the auditory system, hypertension, and cardiovascular disease. However, we haven't the data enough to be available for understanding various effects of noise on the human body. The current study was prospectively designed to investigate the changes of the cardiac factors and cerebral hemodynamics following a transient exposure to noise in young people. 80 subjects (mean aged $23.45\pm2.40$ years) participated in this experiment and were exposed to excavator-noise with 90 decibels for 15 minutes using ear-phone. Cardiac factors such as heart rate (HR), blood pressure (BP) and heart rate-systolic pressure product (RPP), and cerebral hemodynamics such as mean blood flow velocities (Vm), pulsatility indexes (PI), resistance indexes (RI) and mean blood flow velocities at breathing-hold (Vh) in the middle (MCA), anterior (ACA) and posterior cerebral arteries (PCA) were measured before (baseline) and during the noise-exposure. Although there were individual differences in above mentioned parameters, HR, systolic and diastolic BP, RPP, MCA-Vm, MCA-PI, MCA-RI, ACA-Vm, ACA-PI, ACA-RI, PCA-Vm, PCA-PI, and PCA-RI during the noise-exposure decreased compared with the baselines (P<0.05 or P<0.01), The findings of the present study suggest that a transient exposure to excavator-noise at rest causes changes in the cardiac factors and cerebral hemodynamics with individual differences. Further studies need to be carried out for clarifying the effects of longer exposure and combined mental activity with noise exposure.
