Purpose : The purpose of this study was to develop the radiographic technique for detecting the demineralization which is known as indication of dental caries. Materials and Methods : This technique was based on the comparing of multiple radiographs which was irradiated by multiple X-ray spectra. For the meaningful comparing, the multiple radiographs were reconstructed to the dosimetrically consistent images using a standard material. The difference of resulting images of same target with multiple spectra represents the difference of response of material as regards the spectra. Results : We have found about 10% of demineralization of dental hard tissues particularly in the proximal region through the analyzing of differences. Conclusion : Most intriguing thing in this investigation was that the method to analyze difference shows us to an anatomic structure of dental hard tissues even if absolute values of optical density were excluded during the procedures.

악성 흉막삼출액에서 Bleomycin을 이용한 흉막유착설의 시술효과

박정현,김학렬,양세훈,정은택 圓光大學校 醫科學硏究所 2002 圓光醫科學 Vol.17 No.1

목적: 악성 흉막삼출액이 반복적이고 지속적으로 발생하는 경우, 호흡곤란, 흉통등의 증상을 유발시키므로 흉막경화제에 의한 흉막유착술을 시행할 수 있다. 흔히 사용되던 talc의 심각한 부작용이 보고되고 있고, doxycycline 주사제도 국내에서 발매되지 않고 있다. 이에 연자들은 항암제로 소개된 bleomycin을 이용한 흉막유착술의 단기와 중기효과, 부작용 및 생존율 등을 전향적으로 확인하였다. 방법: 2000년 1월부터 2001년 12열까지 원광대학교 부속병원에 내원하여 반복적이고 지속적인 악성 흉막삼출액으로 흉막유착술이 필요한 26명의 환자를 대상으로 특별한 전 처치 없이 bleomycin 60 unit를 식염수와 함께 흉강 내 주입 후, 1일 후의 흉관에 의한 배액량을 확인하고 부작용을 관찰하였으며, 1개월 후에 흉부 방사선상으로 재 저류 유무를 확인하였다. 또한 시술 반응군과 비반응군으로 나누어 중앙생존기간을 비교분석 하였다. 결과: 시술 1일 후 26예중 10예(38%)에서 배액이 없었고, 8예(31%)에서 배액량이 100ml이하였으며, 8예(31%)는 100ml이상이었으나 시술 전보다 감소하였으며 증가된 경우는 없었다. 유의할만한 부작용은 4예(고열 3예, 흉통 1예)에서 발생하였으나, 대증요업으로 조절되었다. 시술 1개월 후 흉부 방사선과 26예중 9예(35%)는 재 저류액이 없었고, 10예(38%)는 저류액이 있으나 시술 전보다 감소하였으며, 1예(4%)는 이전과 변화가 없었고, 6예(23%)는 시술 전보다 저류액이 증가하였다. 시술 후 단기 및 중기효과를 반응군과 비반응군으로 나누어 중앙생존기간으로 양군간을 비교하였을 때, 반응군에서 연장이 되었으나 통계적으로 유의한 차이는 없었다. 결론: 이상의 결과로서 bleomycin에 의한 흉막유착술은 다른 경화제보다 특별한 전 처치가 필요 없는 간편하고, 비교적 부작용이 적은 안전한 방법이며, 효과적인 치료성적을 보이는 시술로 사료된다. Background : Malignant pleural effusions are common and significant problems in patients with advanced malignancy. Repeated thoracentesis provides temporary symptomatic improvement, but most patients progressively cause dyspnea or pleuritic pain. So pleurodesis with sclerosing agent is effective as a palliative treatment. There are many drugs used as pleural sclerosing agents. But doxycycline hasn't been used in Korea since 1999. And recently talc has been reported serious side effects. In this study, pleurodesis with bleomycin was prospectively investigated for its short term and middle period effects and its side effects. Methods : Twenty-six patients with malignant pleural effusion were prospectively analyzed to estimate the effects of bleomycin pleurodesis. Without special management before the procedure, 60 units of bleomycin in 50-100ml of normal saline were instilled into the pleural space via a small bore catheter(8-10 F). Andthen repeated positional changes and rotations were done for 2 hours. We measured the drainage amount and evaluated the side effects after 24 hours and checked the existence of the effusion by chest radiography after 1 month. Results : After 24 hours, the drainage amount showed that the responder group(none or ≤ 100ml) was 69%, and that the nonresponder group(> 100ml) was 31%. Side effects (high fever in 3 cases and severe pleuritic pain in 1 case) were 15%(4/26), but patients recovered easily by symptomatic management. After 1 month, chest radiography showed that the response rate(complete or partial response) was 73%. Differences of survival times between responder and nonresponder group was not statistically significant. Conclusions : We are suggest that bleomycin as a pleural sclerosing agent is a relatively simple, safe and effective agent. But a prospective study with a larger number of patients must be warranted.

연쇄알구균에 의한 급성 인후염 후 발생한 반응성 관절염은 급성 류마티스열의 개정된 진단기준을 충족하지 못하면서, 지속적 혹은 재발성의 비이동성 관절염과 발열, 홍반성 결절, 일시적 간기능 이상 등을 보이면서 심장염과 무도증을 드물게 동반하는 질환이다. 따라서, 발열을 동반한 급성 관절염 환자에서 감별해야 할 질환 중의 하나이며, 심근염 예방을 위한 페니실린 요법의 적응증 및 기간에 대해서는 아직 이론이 많은 상황으로, 보다 광범위한 연구가 필요하다. 저자들은 연쇄알구균에 의한 급성 인후염 1주 후에 발생한 하지의 다발성 비이동성 관절염과 함께 결절홍반 및 일시적 간기능 이상을 보인 환자에서 PSRA로 진단하고 비스테로이드성 항염증제 및 스테로이드로 성공적인 치료를 하였기에 이를 문헌 고찰과 함께 보고하는 바이다. Poststreptococcal reactive arthritis (PSRA) is associated with recent streptococcal infections. However, PSRA is distinct from acute rheumatic fever by its clinical manifestations: non-migrating arthritis, erythema nodosum or erythema multiforme, and transient elevation of serum transaminases. We experienced a 33-year-old man who presented with fever, arthritis of both knees and ankles, and erythema nodosums on extensor surfaces of lower legs which developed 6 days after the onset of pharyngitis symptoms. Blood and urine cultures were negative. Throat culture was negative for group A β-hemolytic streptococcus. The ASO titers increased up to 2080 IU/mL in sequential monitoring. The result of bone scan was compatible to arthritis of both knees and ankles. There were no signs or symptom of carditis. He showed clinical improvement with anti-inflammatory drugs (naproxen 1,000 mg/day and prednisolone 7.5 mg/d). PSRA should be included in the differential diagnosis of patients presenting with arthritis combined with fever.

박관수,정기훈,김효언,정정권,윤규호,전인성 대한악안면성형재건외과학회 2001 Maxillofacial Plastic Reconstructive Surgery Vol.23 No.1

Necrotizing fasciitis is defined as infectious disease showing extensive necrosis of the superficial fascia with widespread involvement of the surrounding tissues and concurrent systemic toxicity. It is found commonly in the extremities, the trunk and the perineum, but shows extremely rare occurrence in the well vascularized area such as head and neck area. Occurred in the head and neck area, it is called "cervicofacial necrotizing fasciitis" (CFNF). It is a fatal disease which carries a mortality rate up to 60%. Early diagnosis, aggressive surgical debridement of necrotic tissues and massive antibiotics therapy are essential for achieving a favorable outcome. We present a case of cervicofacial necrotizing fasciitis in 35-year-old male patient with literature review.

박철완,원형섭,박정배,이근,조상훈,표창해,김상일 대한응급의학회 1996 대한응급의학회지 Vol.7 No.2

Acute arterial occlusion of the extremities is often a surgical emergency and is due mostly to arterial embolus. It has infrequently been reported in the emergency department. Cardiac embolism is most commonly the result of atrial fibrillation secondary to valvular heart disease followed by ischemic heart disease. The emergency arterial embolectomy by Fogarty balloon catheter works well when the cause of occlusion is cardiac embolus obstructing normal vessels in a patient with valvular heart disease. Recently we met some patients with acute critical ischemia of the extremities due to arterial emboli in our emergency department. On physical examination, they all had symptoms of 5"P"s(pain, pallor, pulselessness, paresthesia, paralysis). After emergency arterial embolect omy, immediate improvement was observed in all patients. They were discharged within 1 week. We report our experiences with the review of literatures.

최근 흡연을 시작한 젊은 성언에서 급성 호산구성 폐렴의 발생에 대한 증례가 보고되고 있다. 급성 호산구성 폐렴은 대개 발열을 동반하기 때문에 초기에는 감염성 폐렴으로 잘못 진단, 치료되는 경우가 많다. 아직 정확한 병태 생리 및 조직학적 소견은 밝혀져 있지 않지만 병력 청취 및 임상 양상, 방사선 소견의 관찰을 통해 급성 호산구성 폐렴을 의심하고, 진단을 위해 기관지 폐포 세척액 검사를 시행한다면 좀 더 쉽게 진단 내릴 수 있을 것이다. 본 저자들은 최근 처음 시작한 흡연에 의해 발생한 급성 호산구성 폐렴을 진단하고, 스테로이드를 투여하여 성공적으로 치료한 환자 2예를 경험하였기에 이를 문헌 고찰과 함께 보고하는 바이다. Acute eosinophilic pneumonia(AEP) is characterized by acute febrile respiratory illness associated with diffuse pulmonary infiltration and pulmonary eosinophilia. The specific etiology for acute eosinophilic pneumonia is elusive. By some investigators, cigarette smoking is suggested as a causative substance which can cause AEP. In recent, the authors experienced two cases of AEP following cigarette smoking. Both cases had characteristic features including age around 20 years, new onset smoking before occurance of AEP, diffuse infiltration on chest radiography, pulmonary eosinophilia based on bronchoalveolar lavage and acute improvement after steroid therapy. These clinical features are resemble with previous smoking induced AEP case reports. Base on these clinical features, cigarette smoking associated AEP could be diagnosed more easily.
