The causes of vocal cord paralysis include iatrogenic injury during thyroid or cervical surgery, heart and chest surgery, and tumorous lesion such as laryngeal cancer and lung cancer. In addition to these common causes, rarely, cardiovascular disease can also cause vocal fold paralysis. A disease known as Cardiovocal syndrome, or Ortner’s syndrome, causes left vocal fold paralysis when the left recurrent laryngeal nerve is compressed by the pulmonary artery and aorta, which is occurred by pulmonary hypertension from heart disease. We report for the first case in Korea the diagnosis of vocal fold paralysis caused by Ortner’s syndrome.

Background and Objectives: Since Eustachian tube (ET) plays an important role in the development of middle ear disease, evaluating the function of ET is important. Valsalva maneuver is frequently used, but does not reflect the physiological function. Inflation-deflation test assess both active and passive function of the ET, so it can reflect the physiological function. In our clinic, we use device named EustachiTM to evaluate ET. In this study, we evaluated ET in patients with perforated eardrums using Valsalva maneuver, inflation-deflation test and Eustachi to evaluate the efficacy of Eustachi in assessing ET function. Materials and Methods: 51 dry perforated eardrums were selected. Patients were divided into 3 groups according to the result of the inflation-deflation test; Type A, ET opens in both positive and negative pressure; Type B, ET opens in either positive or negative pressure; Type C, ET dose not open in neither positive nor negative pressure. All patients performed Valsalva maneuver and Eustachi application. Techniques were statistically analyzed and compared. Results: When analyzing whether Valsalva was possible according to the type of inflation-deflation test, there were statistical differences when comparing type A, B and type A, C (p=0.000, 0.024). There was no statistical difference between type B and C (p=1.000). When analyzing the result of Eustachi according to the type of inflation-deflation test, there was no statistical difference between type A and B (p=1.000), while there were statistical differences when comparing type A, C and type B, C (p=0.048, 0.030). Conclusions: Compared with the results of inflation-deflation test, Eustachi can evaluate ET more physiologically than Valsalva maneuver

Non-Hodgkin’s lymphoma from salivary gland origin is rarely found. Parotid gland is the most common site because of its presence of intra glandular lymph nodes. Moreover non-Hodgkin’s lymphoma from the submandibular gland is extremely rare. We report a case of diffuse large B cell lymphoma in the submandibular gland which was initially misdiagnosed as a chronic sialadenitis with fine needle aspiration biopsy.

This study investigates the influences of the perceptions on the dimensions of the library service quality (library staff, supports for the service, library materials and information resources, and facilities and equipments) of academic library users on the customer satisfaction, importance of the services, and the loyalty (reuse intentions). Based on the questionnaires surveyed from 403 undergraduate students of the K University, it analyzed the data using SPSS 12.0. All four dimensions of the service quality influenced statistically on the customer satisfaction. The dimension of the support for the service, importance of the service, and customer satisfaction influenced statistically on the loyalty. 이 연구는 대학도서관의 서비스품질차원(도서관 직원, 서비스지원, 자료 및 정보자원, 시설 및 장비)에 대한 지각이 이용자의 전반적인 만족도, 서비스의 중요성, 충성도(재이용의도)에 미치는 영향을 밝히기 위한 것이다. 이를 위해 이 연구에서는 K대학교 도서관을 이용하는 학부생 403명을 대상으로 설문조사를 실시하였다. 선행연구에 대한 분석을 통해 제시한 인과적 모델을 설문데이터를 바탕으로 SPSS 12.0을 사용하여 경로분석(path analysis) 등을 통해 검증하였다. 분석결과 각 서비스품질차원은 모두 이용자의 전반적인 만족도에 통계적으로 유의한 영향을 미치는 것으로 나타났다. 또한 1개 서비스품질(서비스지원)과 서비스 중요성, 전반적인 만족도는 충성도(재이용의도)에 통계적으로 유의한 영향을 미치는 것으로 나타났다.

Meningioma is one of the most common tumors of the central nervous system. However, primaryextra cranial meningioma is rare as it consists 1%-2% of meningioma. It is very rare inparanasal sinus and accounts for about 0.1% of the paranasal sinus tumor. The treatment ofchoice is complete surgical excision of the tumor. Herein, with a review of the literature, wereport a rare case of primary extra cranial meningioma in a 38-year-old male.
