  • 배경: 이 연구는 외상성 기관-기관지 손상의 특징적인 임상 증상 및 영상학적 소견 등에 대하여 알아보고자 하였다. 대상 및 방법: 2003년 1월부터 2009년 12월까지 본원 응급실을 통해서 내원한 외상 환자들 중에서 수술을 통해서 외상성 기관-기관지 손상으로 진단된 6명의 환자를 대상으로 하였다. 외상의 종류, 동반된 손상, 진단 방법 및 수술까지 걸린 시간, 수술 소견 및 수술 방법, 예후 등에 대해서 조사해 보고 후향적으로 진단에 중요한 인자 등을 알아 보았다. 결과: 손상의 원인으로는 교통사고가 1명, 낙상 및 흉부에 강한 압박을 받은 경우가 5명이었다. 주 증상으로 피하기종, 호흡 곤란, 통증 등이 있었으며 영상소견으로는 기흉, 종격동 기종, 혈흉, 늑골 골절, 폐좌상 등이 있었다. 기관지 내시경을 시행하지 않은 상태에서 2명에서는 흉부 CT 소견에서 기관-기관지 손상이 의심되었지만 나머지 4명에서는 의심하지 못했다. 수상 부위는 기관부위가 2예, 기관지가 4예 있었다. 수술은 개흉술을 통한 일차 문합을 시행하였고 수술 후 사망과 문합 부위 유출은 없었으며 1명에서 술 후 성대 마비가 있었다. 진단에 도움이 되는 특징적인 소견으로는 흉관 삽입 후 음압의 적용에도 불구하고 지속적인 심한 폐 허탈이 가장 중요한 소견이었으며, 흉부 CT에서의 기관-기관지의 주행 경로의 단절이 진단에 중요하였다. 결론: 외상성 기관-기관지 손상은 의심하지 않으면 진단이 쉽지 않으나, 특징적인 흉관 삽입 후의 임상 증상과 영상 소견은 진단에 큰 도움을 주었다.

  • In spite of great advances in surgical treatment during past several decades, surgery of the trachea failed to develop correspondingly, partly because of relative rarity of the tracheal lesions and partly because of difficulties in surgical technique and anesthesia. Surgical diseases of the trachea are largely obstructions due to neoplasm or cicatrical stenosis and tracheal malacia. The present treatment of respiratory failure, using cuffed endotracheal and tracheostomy tubes, has produced, apparently with increasing frequency, tracheal stenosis, tracheomalized tracheal erosion. Surgery is presently the only reasonable way to treat stenotic lesions of the tracheobronchial tree. In the case of tumors, the current trend has been that of radical excision. Primary end-to--end reconstruction of the trachea has been generally recognized as the ideal method of repair following resection. However, for decades it was believed that a maximum of four tracheal rings only might be excised and primary healing achieved with safety. A great variety of procedures, developed by numerous investigations and directed at tracheal substitution, have almost invariably met with discouraging results. A meticulous study done by Grillo and associates on autopsy specimens has shown that an average 6.4cm of mediastinal trachea can be safely resected by full mobilization of the right lung and transplantation of the left main bronchus into the bronchus intermedius. Recently, we experienced a case of successful resection of a tumor of the tracheal carina and primary tracheo-left main bronchial anastomosis at the Department of Thoracic & Cardiovascular Surgery, the National Medical Center in Seoul. The patient, a 29-year-old man, was admitted to the hospital with complaints of dyspnea and cough. On admission, chest film showed hydropneumothorax on the right. After closed thoracostomy, hydropneumothorax disappeared, but hazy densities, developed in the right middle and lower lung fields, resisted to treatment. Bronchoscopy uncovered irregular tumor covering the carina and the right main bronchus, and biopsy indicated well differentiated squamous Cell carcinoma. Operation was performed on July 2, 1975. A right postero-lateral thoracotomy was used. Excision involved the lower trachea, the carina, the left main bronchus and the right lung. This was followed by direct anastomosis between the trachea and the left main bronchus. Bronchography was done on 17th postoperative day revealed good result of operation without stricture at the site ofanastomosis. About one month after the operation symptoms and signs of bronchial irritation with dyspnea developed, and these responded to respiratory care. On 82nd postoperative day, sudden dyspnea developed at night and the patient expired several hours later. Autopsy was not done and the cause of death was uncertain.

  • Broncholiths are defined as calcified materials that occur in a tracheobronchial tree or in a cavity communicating with that. Broncholith has variable clinical features. The therapeutic options to remove broncholiths are so variable that clinicians need to select the most safe and effective methods by mass size, mobility, and location. As yet, there is no consistent guideline removing a broncholith. We report 2 successful cases of removing a fixed broncholith by flexible bronchoscopy guided cryoadhesion. With repeated technique of thawing and freezing with cryoprobe, we could extract the fixed broncholith safely. This method is promising as a way to remove broncholith in the future.

  • Lung cancer is a leading cause of cancer death worldwide; however, despite major advances in cancer treatment during the past two decades, the prognostic outcome of lung cancer patients has improved only minimally. This is largely due to the inadequacy of the traditional screening approach of diagnosis in lung cancer, which detects only well­established overt cancers and fails to identify precursor lesions in premalignant conditions of the bronchial tree. In recent years this situation has fundamentally changed with the identification of molecular abnormalities characteristic of premalignant changes; these concern tumour suppressor genes, loss of heterozygosity at crucial sites and activation of oncogenes. Basic knowledge at the molecular level has extremely important clinical implications with regard to early diagnosis, risk assessment and prevention, and therapeutic targets. In this study we used a 'cap-finder' subtractive hybridization method, 'long distance' polymerase chain reaction (PCR), streptavidin magnetic beads mediated subtraction, and spin column chromatography to detect differential expression genes of human small cell lung carcinoma. We have now isolated ninety two genes that expressed differentially in the human small cell lung carcinoma cells and analyzed of 12 clones with sequencing, nine cDNAs include tapasin (NGS-17) mRNA, BC200 alpha scRNA, chromosome 12q24 PAC RPCI3-462E2, protein phosphatase 1 (PPPICA), translocation protein 1 (TLOC1), ribosomal protein S24 (RPS24) mRNA, protein phosphatase (PPEF2), cathepsin Z, MDM2 gene and three novel genes. They may be oncogenesis­related proteins.

  • 폐방선균증은 Actinomycosis israelii에 의해 발생되는 만성, 화농성, 육아종성 질환이다. 주로 구강내 또는 상부위장관에 정상적으로 존재하며, 구인도의 상부위장관에서 오염된 분비물의 흡인에 의해 기관지를 통해 흉곽내로 들어간다. 주로 만성적인 기침, 객담, 혈담, 미열, 흉통, 체중감소 등의 증상을 나타내며, 흉부 방사선 검사상에서는 종괴양 병변이나, 폐침윤, 농양, 결핵과 비슷한 소견을 보이며, 악성 종양과의 감별진단은 어려운 것으로 알려져 있다. 따라서 대개 진단 및 치료를 위하여 수술이 필요하며 수술후 조직학적 검사상에서 유황과립을 포함하는 실모양의 개체를 확인하면 확진할 수 있다. 치료는 페니실린이 가장 좋은 약으로 알려져 있으며, 구인도나 치성 농양의 치료나 재발을 방지하기 위하여 수술 후 2개월 내지 3개월 가량 사용하는 것이 좋을 것으로 생각된다. 본 저자들은 방사선학적으로 폐암이 의심되었던 환자에서 종괴 절제후 방선균증을 확진 및 치료하여 문헌고찰과 함께 보고하는 바이다.

  • Cortex mori (Morus alba L.), the root bark of mulberry tree, has been used as an antiphlogistic, diuretic, and expectorant in herbal medicine. The purpose of this study was to determine whether Cortex mori could inhibit the ovalbumin (OA) -induced late asthmatic reaction in guinea pigs. Guinea pigs were sensitized by two exposures to an aerosol of OA(1.0%) and then challenged with aerosolized antigen(2.0%), The animals were pretreated by three inhalations of the aerosoled Cortex mori either before antigen sensitization or cahllenge. Bronchoalveolar lavage fluid(BALF) and peripheral blood were collected at 17 hours after OA challenge. The cell populations in BALF and peripheral blood were examined to determine the changes of the relative proportions of eosinophils,neutrophils and mononuclear cells etc. Beta-glucuronidase activity in BALF was measured to evaluate the alveolar macrophage activation. OA-induced histamine release from guinea pig peritoneal fluid cells was measured by radioisotope enzymatic asssay. Results were as follows. The number of eosinophils, neutriphils and lymphocytes recovered in BALF were significantly increased in the 17h following aerosol challenge with OA. Among them, eosinophil and neutriphils were decreased remarkably in group that had been preinhalated with Cortex mori. The number of lymphocytes in BALF were not decreased in group pretreated with CM before sensitization but decreased in Group pretreated with CM before challenge. After OA challenge, the number of eosinophils in peripheral blood were markedly increased, but Cortex mori inhibited significantly the OA-induced eosinophilia. Beta-glucuronidase activity in the supernatants of BALF were significantly increased in the 17h following aerosol challenge with OA, however, pretreatment of Cortex mori had no influence on Beta-glucuronidase activity, suggesting that Cortex mori had no inhibitory effect on OA-induced alveolar macrophage activation. Cortex mori inhibited the OA-induced histamine release from guinea pig peritoneal fluid cells. From the above results, it is suggested that Cortex mori contains some substances with an activity to inhibit the the OA-induced late phase reaction of the bronchial asthma in guinea pigs.
