Benign schwannoma is the most common neurogenic tumor in the mediastinum. Mediastinal benign schwannomas are most often asymptomatic and rarely accompanied by bloody pleural effusion. In the clinical analysis of 7 cases of pulmonary schwannomas, pleural effusion, and blood invasion were evident in 3 patients with malignant schwannoma. Herein, we report a rare case of giant, benign schwannoma presented with total collapse of right lung by massive, bloody pleural effusion.

라돈이 기관지나 폐포에 머무르게 될 때 라돈의 붕괴로 인해 자핵종(알파선, 베타선, 감마선 등)들이 생성되면서 이것들이 방사선을 방출하는데 세포의 염색체에 돌연변이를 일으켜 폐암을 발생할 가능성이 존재한다. 다시 말해 폐암의 원인이 라돈가스 때문이라기보다는 흡수된 일부 라돈의 붕괴로 인해 생기는 부산물이 방사선을 방출하기 때문이라고 할 수 있다. 사람이 연간 노출되는 방사선의 82%가 자연방사선에 의한 것인데 그중 대부분이 라돈이다. 실내의 라돈 농도를 적절하게 제어할 수 있다면 폐암의 발생확률을 30%나 억제할 수 있다고 알려져 있다. 아직까지 실내의 라돈의 농도를 측정하는 데는 외국의 라돈 센서를 사용하고 있는 실정이다. 실내 라돈 방출량에 대한 데이터 구축과 국내에 맞는 실용적인 라돈측정기기를 개발하도록하는 연구가 필요하다. 본 논문에서는 PIN Photodiode를 이용하여 라돈의 농도를 측정하는 라돈 검출기 구현 방법을 제안한다. 실험을 통해서, PIN photodiode의 라돈 센서 모듈로서의 이용 가능성에 대하여 확인하였다.

괴사성 기관지 국균증은 대부분 면역 기능이 저하된 환자에서 발생하며 국균이 기관지 상피를 침범하여 기관지 내에 종괴나 협착을 유발하는 질환이다. 당뇨병이 있는 78세 남자가 호흡곤란과 기침을 주소로 내원하여 시행한 단순 흉부 X-선 촬영과 흉부 전산화 단층 촬영 결과 좌상엽 기관지를 완전히 막고 있는 종괴와 좌상엽의 허탈이 발견되었고, 기관지 내시경을 통한 생검 결과 만성 염증 소견을 보였다. 확진과 치료를 위해 시험적 개흉술을 통해 좌상엽 소매 절제술을 시행하였고 치종 조직검사 상 괴사성 기관지 국균증으로 진단되었다. 저자들은 당뇨병이 있는 고령의 환자에서 발생한 괴사성 기관지 국균증 1예를 문헌 고찰과 함께 보고하는 바이다.

We report on a Soeumin patient with spontaneous sweating after a lung segmentectomy resulting from aspergillosis. During her inpatient stay, the patient received Soeumin Gwakhyangjunggi-san, Hwanggigyeji-tang, and Seungyangikgi-tang for herbal medication. She also received acupuncture, moxibustion, pharmacopuncture, and cupping therapy. A numeric rating scale (NRS) was used to assess the improvement of symptoms. Sweating was reduced, as reflected by an NRS change from 7 to 0, when the herbal medication changed from Soeumin Gwakhyangjunggi-san to Hwanggigyeji-tang. General weakness and chest discomfort were also relieved after using Hwanggigyeji-tang and Seungyangikgi-tang. These results suggest that Hwanggigyeji-tang and Seungyangikgi-tang are clinically effective for Soeumin patients who are appropriately diagnosed with yang collapse syndrome in the postoperative setting.

An 8-month-old male orangutan (Pongo pygmaeus) housed in Everland Zoo-logical Gardens died after having 10 day history of depression, anorexia and acute respiratory distress. On necropsy, the lung failed to collapse and showed diffuse red consolidation. Microscopically, the alveoli were filled with large amounts of red blood cells, fibrin and varing number of hemosiderin-laden macrophages. The alveolar septa were thickened due to infiltrated mononuclear cells and congestion and are occasionally necrotic. Escherichia coli was isolated from the lung, spleen and kidney. The result of antibiotic sensitivity test of the isolated organism was also described.

Atelectasis may be defined as collapse of the lung due to absence of air within the alveoli. It may involve anatomic segments, lobes, or whole lungs but also may be a diffuse miliary process, as in the adult respiratory distress syndrome. The key to treatment are the anticipation and prevention of atelectasis in various clinical situations, the recognition and treatment of underlying disease, and the prompt initiation of vigorous treatment once atelectasis is found. Repeated assessment by physical examination is necessary to determine the presence of atelectasis and its response to treatment. During the period of January, 1981 to October, 1990, 100 patients with atelectasis were treated in the department of Thoracic and Cardiovascular Surgery, Pusan National University Hospital. There were 70 males and 30 females ranging from 3 days to 79 years of age. The occurrence ratio of right to left side was 2.1 : 1. The underlying pathologic lesions of atelectasis were pneumonia with effusion(28), lung ca.(24), pulmonary tuberculosis(24), and chronic empyema(9), The treatment procedure for atelectasis were closed thoracostomy in 26 cases, ressection in 21 cases, therapeutic bronchoscopy in 14 cases and etc.

A twenty three year old, Primigravida and 32 week pregnant woman who has been complained dyspnea, chest pain, nausea and vomiting was admitted to this chest surgical department on Feb. 19, 1979. Physical findings were those of acutely ill appearance, decreased thoracic excursion and absence of breath sounds in the left hemithorax. Roentgen examination of the chest revealed reticular cystic densities in the left, particularly in lower lung field with collapse of the left lung. Correction of the diaphragmatic hernia was carried out with reduction and repair of the hernia through transperitoneal approach. On exploration, the defect of the diaphragm was 12 x 12 cm in size and was located posterolateral area of left diaphragm. Hernia contents were stomach, spleen, omentum and splenic flexure of large bowel. The baby was normal full term spontaneous delivered at 36th POD. Diaphragmatic hernia complicated by pregnancy is a rarity and mortality is extremely high. Therefore, the literatures have reviewed and the case is reported.

Transposition of the great arteries is one of the commonest forms of severe congenital heart disease and produces severe cyanosis threatening survival from the day of birth. Anatomical anomalies which the aorta arises from the infundibulum of the right ventricle and the pulmonary artery arises from the outflow tract of the left ventricle make the deranged circulation. Survival is possible only if additional anomalies are present which allow mixing of the pulmonary and systemic circulations. Preoperative diagnosis as TGA was taken on the 15 day old female via the preoperative examination and the right cordioangiography. As palliative treatment for cyanosis, Blalock-Hanlon operation was performed in this patient. The results were good as 54 mmHg changed from 27 mmHg of $PO_2$ in aorta, but sudden cardiac arrest was developed in postoperative 12 hours. In order to confirm the cause of death and the cardiac anomalies, autopsy was performed on the date of death. The diagnosis of the autopsy showed; [1] Transposition of the Great Arteries. [2] Patent Ductus Arteriosus. [3] Patent Foramen Ovale. [4] Ventricular Septal Defect, 2 Muscular Type. [5] Double Ureter, Right. [6] Artificial Atrial Septal Defect. [7] Total Collapse of the left lung and Intraparenchymal hemorrhage of right lung.

Pneumothorax, a frequently encountered disease in the clinic, has been interesting to surgeons for it`s high recurrence rate. 52 patients with a second attack of pneumothorax at our hospital in a 24 month period were evaluated especially for the risk factors of recurrence. The results were as follows:1. Patients after operative treatment[21 cases There were no postoperative complications and recurrence.2. Patients with tube drainage or conservative treatment [31 cases [i Overall recurrence rate was 45.2 %. [ii Suggestive risk factors for the recurrence were: age above 30 years, short period of thoracostomy less than six days. And other factors such as male, right lung, higher level of lung collapse were thought to be followed further more.

Mycoplasma pneumoniae에 의한 폐렴의 임상양상은 다양하다고 알려져 있으며, 흉부 방사선 소견상 대부분 기관지 주위 폐렴이나 반점형 폐 침윤 양상을 보이고 폐허탈은 5% 정도로 매우 드물게 발생하는 것으로 되어 있다. 본 저자들은 미열, 두통, 건성 기침, 근육통 등 비정형적인 폐렴의 증상을 보이면서 대엽성 무기 폐로 발현한, 마이코플라즈마 폐렴을 경험하였기에 이를 보고하는 바이다.
