허리는 요추(허리척추뼈), 척추골사이의 디스크(추간판), 척추와 디스크 주위의인대, 척수와 신경, 요추의 근육, 골반과 복부내의 기관들로 구성되어 있다. 우리 몸에서 고장이 잘 나는 곳은 움직임이 많은 곳이다. 사지도 움직임이 많은 관절에 고장이 잘 생긴다. 척추의 움직임이 많은 곳은 허리이다. 허리는 매우 불안정하여 전 인구의 약80%가 한번은 통증을 경험한다고 한다. 이러한 허리통증은 일반적으로 일상생활에서의 잘못된 자세와 생활습관에 기인하는 경우가 많다. 수술이나 치료 후에도 자세와 생활습관을 교정하지 못하면 재발의 경우가 있는 등 환자 자신이 허리통증에 대한 이해와 노력이 없으면 궁극적인 치료를 기대하기 어려우므로 환자 자신의 관심과 노력이 무엇보다 중요하다.이번 호에서는 인체의 신비 허리에 대해 척추전문에스병원 이승철원장과 경희대학교 동서신의학병원 척추센터 김기택 교수의 도움말로 알아본다.

Acquired, nonmalignant tracheoesophageal fistula is an uncommom and difficult problem to manage. The most commom cause is a complication of endotracheal or tracheostomy tubes. Most are diagnosed while patients still require mechanical ventilation. The principle of treatment is two stage operation. First, new tracheostomy tube is placed so that the baloon is below the fistula, and gastrostomy and feeding jejunostomy are made for the drainage and feeding. Finally after weaning from the mechanical ventilation, tracheal resection and reconstruction are made, and the esophageal defect is closed in two layers and a viable strap muscle interposed into the two suture site to prevent recurrence. Recently, we experienced a case of acquired nonmalignant tracheoesophageal fistula which was developed during mechanical ventilation. She was successfully treated with the above two stage operation.

Primary benign tracheal tumors are exceedingly rare and leiomyoma has the least frequency among them. It is important to recognize early without misdiagnosis such as asthma because it is curable. A 41 year-old female was admitted for dyspnea and choking since November 1991. Under the impression of asthma, she received medication. Symptom was not improved and thus chest CT scan was performed. There was endotracheal tumor mass which was located just above the carina and arose from the right lateral tracheal wall with broad base. We successfully resected the tumor mass including trachea and the defected area of trachea was reconstructed with autologous graft using pericrdium & rib cartilage. During the follow up period, no complication was developed.

Mucoepidermoid carcinoma of the lung is extremely rare. This rare tumor arise beyond the carina, usually main stem bronchi, but occasionally in lobar or segmental airways, This tumor presents with symptoms of bronchial irritation or obstruction. Distant metastasis is an uncommon, therefore complete surgical resection is the treatment of the choice. The prognosis of this tumor correlates with the histologic grade of the tumor. We experienced a case of mucoepidermoid carcinoma arising from the right middle lobe, which was treated with the right middle lobectomy, with good result. We report this case and follow-up of the patient.

비짜루과 둥굴레속(Asparagaceae: Polygonatum)은 전 세계적으로 약 90여 종이 알려져 있으며, 유럽, 북아메리카, 아시아 등 북반구 온대 지역에 집중적으로 분포한다. 국내 둥굴레속 분류군은 총 16분류군이며, 이중 잎이 호생하고, 난형에서 타원형 모양의 엽질성 포를 가지며, 화피통 내부에 털이 없고, 수술대 표면에 돌기가 나있는 분류군들은 용둥굴레열(series. Bracteata)에 속한다. 그러나 이들은 종간 교잡 또는 주요 기관의 형질 변이가 다양하여 중간형질을 보이는 개체군들에 대한 종 식별에 많은 어려움이 있었다. 경남 창원시에서 채집된 목포용둥굴레(P. cryptanthum) 변이 개체집단는 기존의 목포용둥굴레와 달리 식물체 높이와 화경·소화경이 길며, 포 부착위치의 변이 폭이 넓으며, 포가 타원형이고 밖으로 말리는 습성으로 형태적 차이가 나타났다. 따라서 본 연구에서는 명확한 분류학적 실체를 구명하고자 분자생물학적 계통분석(nrDNA ITS + cpDNA matK, trnK-rps16, rps16, rbcL) 연구를 진행중에 있다.

Background : Primary malignant tumors of the trachea are extremely rare entities and account for a mere 0.1 per cent of all malignancies of the respiratory tract. Because of vague localizing signs, symptoms and a usually negative routine chest film, the patients with tracheal tumors are often treated for asthma or chronic obstructive pulmonary disease for considerable period of time before correct diagnosis. Method : We have made a review of the 17 cases of primary tracheal tumors in recent 15 years. We reviewed the clinical features including history of smoking and respiratory symptoms, the official readings of initial routine chest film, the cytologic examination of sputum, the time of delay in diagnosis, and the response according to the therapeutic modalities. Results : Eight out of 9 patients with squamous cell carcinoma(SCC) were above 50 years old, five out of 6 patients with adenoid cystic carcinoma(ACC) were below 50 years old. The most common location of primary tracheal tumors was the upper one-third of trachea in 8 cases(47%). The most frequent symptoms were dyspnea in 13/17 cases(76%) and then stridor or wheezing, cough. and sputum in order. The routine chest roentgenographic examinations were not helpful to diagnose tracheal carcinoma and the cytologic examinations of sputums were helpful to diagnose tracheal carcinoma in only one case with adenocarcinoma. The mean times of delay in diagnosis of patients with sec and ACC were 5 months and 24.9 months respectively. We had bronchial asthma in 8 cases(47%) and tracheal tumors in 4 cases(23%) as initial clinical impression. Conclusion : We would like to perform more comprehensive diagnostic tools(high KVP technique, the fibroptic bronchoscopic examination, chest CT scan etc.) in patients who had the suggestive points for the tracheal tumorse(1. unexplained hemoptysis or hoarsness, 2. inspiratory wheezing or stridor, 3. wax and waning of dyspnea according to changes of position, 4. progressive asthmatics unresponsive to antiasthmatic therapy) and radical resection of tumor or external radiation therapy with curative aim as possible.

Purpose: There is a growing concern for the cost management of medical institutions. The purpose of this study was to estimate Activity-Based Costing (ABC) for dental implant cost. ABC refers to allocating resources or cost based on the activities of services. Materials and methods: A dental institution located in the metropolitan area was selected in this study. The tax accounting data of the institution were utilized to confirm total cost, and the institution was asked to make out clinical activities to figure out what activities were carried out. The direct cost and indirect cost for dental implant were separately estimated, and cost driver was analyzed to estimate the indirect cost accurately. Results: The rates of the direct and indirect cost respectively stood at 35.8 and 49.5 percent. The cost for a dental implant was found to be approximately 1,579 won, and the cost of prosthetic surgery and treatment that included implant surgery accounted for the largest portion of the cost, which was 470 thousand won (30%). And the weight of training and education on dentistry was relatively higher than that of the other kinds of treatment. Conclusion: In order to ensure accurate and scientific costing for dental implant, not only direct medical procedure but every pre- and post-procedure activity should fully be taken into account. Pre-activities, post-activities, education and training are included in the indirect cost, but all these activities are mandatory and associated with the quality of treatment and the satisfaction level of patients.

Treacher Collins syndrome (TCS) is autosomal dominant disorder that occurs approximately 1 in 25,000 to 50,000 live births. The main signs of syndrome are hypoplasia of facial bone and microtia. One in third of them is associated with cleft palate and often shows dental hypoplasia. TCS patients need several number of surgery with general anesthesia throughout their life time for recovery of function and esthetic. Endotracheal intubation of TCS patient is very difficult due to microstomia, retrognathia, choanal stenosis, and decreased oropharyngeal airway. Therefore, general anesthesia of adolescent TCS patient with immature incisor roots has high risk of causing dental trauma. This case is regarding TCS patient who was referred to the Department of Pediatric Dentistry, Yonsei University for avulsed upper left central incisor during endotracheal intubation. The purpose of this report is to emphasize the usefulness of mouth guard to prevent dental trauma when endotracheal intubation is needed for TCS patient.

Background: Hemoptysis is a common clinical symptom, responsible for 11% of admission to the hospital chest service. Correct diagnosis, accurate localization of the bleeding source and proper management are imperative to reduce the risk of massive hemoptysis. We performed the study to define the optimal time of fiberoptic bronchoscopy in 63 patients with hemoptysis admitted to Kyung Hee University Hospital between Aug 1989 and Aug 1992. Methods: Retrospective analysis of medical records concerning the cause, amount, duration of hemoptysis and the timing of fiberoptic bronchoscopy in 63(M:F=36:27) patients. Results: 1) The main causes of hemoptysis were pulmonary tuberculosis(52.4%) bronchiectasis(27.0%) and lung cancer(11.1%). 2) The bleeding sites were localized in 26 patients(41.3%). 3) The rates of localization of bleeding site were not related to the amount and duration of hemoptysis. 4) The rates of localization of bleeding site were 61.8%(21/34) during hemoptysis, 18.2%(22) within 24hr after resolution of hemoptysis, 14.3%(1/7) thereafter. Conclusion : Early bronchoscopy, especially during hemoptysis may show higher rates of successful localization than delayed bronchoscopy.
