기관협착증은 이비인후과 영역에 있어서 치료가 어려운 질환중의 하나로 이의 재건에는 여러가지 자가조직이 각각의 장점에 따라 사용되어 왔지만 완전하고 만족할만한 결과를 얻지 못하는 실정이다. 저자들은 가토의 자가 늑연골 (1군) 및 늑연골막 (2군)을 이용한 기관 재건술을 시행하여 다음과 같은 결과를 얻었다. 1) 이식편은 술후 10주 (1군) 및 12주 (2군)에 흡수나 섬유조직으로의 대치는 없었으며, 기관강의 크기는 직상 하부의 정상기관과 큰 차이가 없었다. 2) 늑연골을 이식한 부위는 연골막의 내세포층에서 연골세포가 분화, 이동되어 절단된 연골사이로 이동하여 새로운 연골을 형성하였다. 3) 늑연골막을 이식한 부위는 연골막에서 형성된 연골세포 및 연골기질이 절단된 연골사이로 이동하여 새로운 연골을 형성하였다. 4)) 이식한 부위의 점막층은 점막재생이 이루어져 원주상피로 피복되었다. 5) 기관 전벽의 결손부위는 늑연골 및 늑연골막을 이용하여 성공적으로 재건되었다.

A 4-year-old, neutered male Shih-tzu dog weighing 5.4 kg was referred due to anorexia and chronic coughing. Based on history, physical examination, laboratory tests, radiographic findings, echocardiography, and bronchoscopic examination, the dog was diagnosed as tracheobronchial foreign body. The foreign body was steamed rice debris, which was removed by bronchoalveolar lavage (BAL) with vacuum suction of bronchoscopy. Bacterial and fungal culture of collected BAL fluid was negative. Baermann test for lungs parasites also was negative. The dog was treated with bronchodilator, antibiotics, anti-inflammatory agent, and mucolytics for 7 days. Appetite increased and coughing sign was clearly improved after removal of foreign body and medical therapy. This case report describes that bronchoscopic techniques are available for the evaluation and management of airway foreign bodies.

Diffuse tracheobronchial amyloidosis is an uncommon form of pulmonary involvement, and causes prolonged cough, dyspnea, wheezing and repeated development of pneumonia. We report a case of diffuse tracheobronchial amyloidosis in 58-year-old woman that was traeted by repeated electrocautry under flexible fiberoptic bronchoscopy. The patient had a long-standing history of dyspnea and was admitted due to resting dyspnea, which was aggravated to impending respiratory failure after diagnostic procedures. We applied repeated electrocautry to the endobronchial amyloid tumors and successfully reduced bronchial stenosis and the pateint didn't feel dyspnea. We suppose that, in certain cases of tracheobronchial amyloidosis patients, endobronchial electrocautry would be a helpful procedure.

Tracheobronchial rupture is one of the less-common injuries associated with blunt chest trauma. The diagnosis of tracheobronchial rupture is not easy, but failure to diagnosis may lead to death or long-term disability. Early diagnosis and appropriate management can reduce the mortality and morbidity. Bronchoscopy is the diagnostic method of choice for patients with tracheobronchial rupture. We report a case of tracheal rupture after blunt chest trauma. A 40-year-old man was transferred to our hospital for dyspnea after blunt chest trauma. He was promptly diagnosed as tracheal rupture by fiberoptic bronchoscopy and chest computed tomogram. He was successfully managed by thoracotomy and primary repair.

Early diagnosis of autism and intervention of medical treatment are very significant to develop specific social communication skill for children with autistic spectrum disorders (ASDs). But they have difficulties in medical treatment because of lack of a public welfare institution and special medical system. In particular, few children can access such treatment and the existing single-therapist clinics are inefficient with regard to cost and time. Therefore, new methods should be studied for developing various products, services, and systems for autistic children. This study discusses the potential use of an interactive design as assistive technology for such children. We utilize the experience gained in the collaborative design of the interactive therapy system (ITS). The key methods include a collaborative design with rapid interactive prototyping, heuristic evaluation, user-centered process, VR technology, tangible interface, and scenario-based contents. We applied these methods to the ITS and proved the efficiency of interactive design as an assistive technology through clinical experimentation.

Quality Assurance (QA) is essential to provide effective hyperthermia, but in the case of a problem with a hyperthermia cancer therapy system in Korea, the manufacturers or venders are repairing and maintaining the system. In Korea, if an error occurs in the hyperthermia system, the manufacturer and sales agent are repairing and maintaining it. There is no QA protocol suitable for the domestic situation. This study is based on the QA guidelines recommended by institutions such as European Society for Hyperthermia Oncology (ESHO), Hellenic Society of Oncologic Hyperthermia (HSOH), and the results of questionnaires to hospitals that have hyperthermia cancer therapy systems in Korea. By developing an optimized QA protocol, we aim to reduce the errors and inaccuracies that can occur in during hyperthermia such as measurement of temperature, instrumentation, and heat transfer. In addition, we will visit a hospital with a hyperthermia cancer therapy system in Korea to perform a QA based on this study, and study to specify tolerances and accurate QA set-up parameters using the measured QA results.

Background : The nationwide tuberculosis registry system in Korea has been operated with the dual reporting system - public health center (PHC) and private medical services (PMS) - since 2000. While three-fifths of the registered cases in 2002 was reported by PMS, it was reported that the success rate of patients at PMS was lower than that at PHC. To identify the problems of the patients' management at the PMS as well as the PHC in a community is the aim of this paper. Methods : The subject was selected from the registered cases of the pulmonary tuberculosis in Jejudo, 2002. The needed items for this study were gathered by the reviewing the medical charts directly. Results : Of the 262 patients included in the subject, 92 cases (35%) were treated initially at PMS. The sputum smear as an essentially diagnostic test was carried out with 69.2% at private clinics compared with 98.2% at PHC. The success rate of the treatment at PMS was 59.8% so that it had a statistically significant difference from that at PHC (80.0%; p<0.01). Conclusion : These results showed that there were several problems in diagnosis and treatment for the patient of pulmonary tuberculosis at PMS. To improve the success rate of the treatment at PMS, the nationwide clinical guideline for control of pulmonary tuberculosis should be systematically disseminated and strongly recommended at PMS by the government.

경동맥 파열은 악성 종양으로 인한 두경부 수술의 1-5%에서 발생하고 80%의 사망률과 생존자의 50%에서 신경학적 후유증을 나타낸다. 저자들은 수술전ㆍ후 방사선치료를 받은 환자 2례에서 경동맥파열을 경험하였다. 제 1례는 51세의 남자로서 후두암($T_4$NoMx)으로 후두전적출술과 6120 rad의 수술후 방사선 치료 후 좌측 악하 부위에 악성 종양의 경동맥 침윤으로 시험적 수술후 6일만에 경동맥 파열로 사망하였다. 제 2례는 51세의 남자로서 하인두암($T_3$$N_2$Mx)으로 7200 rad의 수술전 방사선치료후 악성 종양의 재발로 후두전적출술과 일측의 근치적 경부곽청술후 누공을 형성하여 수술후 14일만에 경동맥 파열로 사망하였다.
