박준동,전민희,김성진 충북대학교 의과대학 충북대학교 의학연구소 2010 忠北醫大學術誌 Vol.20 No.1

연구목적: 종격동기종의 원인을 감별하는데 유용한 CT 소견을 분석하고자 하였다. 대상 및 방법 : 종격동기종 환자 39명을 대상으로 후향적으로 분석하였다. 모든 CT 촬영은 얇은 절편의 CT 영상이 포함되었고, 증상이 있거나 시술을 시행한 후 24시간 이내에 시행되었다. 종격동기종은 그원인에 따라 외상성(n=16), 의인성(n=10), 자발성(n=13)으로 분류하였다. 기관지혈관속은 기관용골(tracheal carina)부터 제2기관용골(second carina) 기시부까지를 main, 제2기관용골부터 엽기관지의 원위부까지를 lobar, lobar보다 변연부를 segmental 분류하였다. CT 영상에서 기관지 혈관속을 따라 존재하는 선상 또는 환상의 관외 공기음영을 분석하였다. 결과: Lobar 와 segmental 수준에서 자발성(각각 100%, 84.6%)과 외상성(각각 31.3%, 37.5%)에서는 관외 공기음영이 관찰된 반면, 의인성에서는 모든 예에서 관찰되지 않았다. 양측 모두에서 관찰되었던 경우는 Lobar 와 segmental 수준 모두 자발성(각각 61.5%, 45.5%)으로 외상성(각각 40%, 16.7%)보다 많았으나 통계적으로 유의한 차이는 없었다.(p.>0.10). 결론: 종격동기종의 감별에 도움을 주는 Macklin 효과의 존재여부는 제2기관용골 이하 lobar 수준에서 분석하는 것이 효과적일 것으로 사료된다. Purpose: The aim of this study is to evaluate the useful CT findings for differentiation of the causes of pneumomediastinum. Materials and Methods: Thirty-nine patients with pneumomediastinum were retrospectively evaluated. All CT scans included thin section CT, and were obtained within 24 hours after presentation of symptom or procedure. We classified the causes of pneumomediastinum as traumatic (n=16), idiopathic(n=13), and iatrogenic (n=10). Also, we classified the level of the bronchovascular bundle as main (from carina to second carina), lobar (from second carina to the distal portion of lobar bronchi) and segmental (below the level of lobar bronchi). On CT scans, linear or round extra-luminal air densities along the bronchovascular bundles were evaluated. Results: At the level of lobar and segmental, extra-luminal air density was seen in idiopathic (100%, 84.6%) and traumatic (31.3%, 37.5%), however, was not seen in iatrogenic in all cases. Extra-luminal air density in both lungs at the level of lobar and segmental was more common in idopathic (61.5%, 45.5%) than in traumatic (40%, 16.7%), however, it did not show statistical significance. Conclusion: The Macklin effect that is helpful in the differentiation of pneumomediastinum should be evaluated at the lobar level below the second carina.

Fluoroscopy-Guided Treatment of a Bronchopleural Fistula with a Platinum Vascular Occlusion Coil and N-butly-2-cyanoacrylate (NBCA) : A Case Report

박준동,배일헌,박길선,김성진,전민희,홍종면 대한영상의학회 2009 대한영상의학회지 Vol.61 No.6

A bronchopleural fistula (BPF) following a pulmonary resection is relatively rare; however, it has high morbidity and mortality rates, despite advancements in treatment. Treatment options for a BPF include surgical procedures, conservative therapy, medical therapy, and in particular, the use of a bronchoscopy and different glues, coils, and sealants. This paper discusses a case of the treatment of a postoperative BPF, which is not identified on the bronchoscope, using a platinum vascular occlusion coil (microcoil) and N-butly-2-cyanoacrylate (NBCA) under fluoroscopic guidance. We hereby assert that such an approach as a combination might be an improvement to the minimally-invasive treatment methods currently in use.

Summary feedback group(20) and immediate feedback group(20) are divided to have flat serve practice by selecting 40 physical education major male students of Pusan D-university with no experiencing tennis, to examine how summary feedback effects on tennis serve skill learning, in this study. Acquisition stage is practiced to exercise total 300 times (respectvely 20 times : 5 times for a week during 2 weeks) Retention stage is practiced to exercise total 60 times without feedback. As the above results, the conclusions are as follows : 1. The performance of groups received immediate feedback is found to have more a great improvement than that of groups received summary feedback, especially, in acquisition stage(P<.01). 2. The performance of groups received summary feedback is found to have more a great improvement than that of groups received immediate feedback, especially, in retention stage(P<.05).

Schwannoma of the Aryepiglottic Folds: A Case Report

박준동,이승영,차상훈,조범상,전민희,배일헌 대한영상의학회 2010 대한영상의학회지 Vol.62 No.1

A schwannoma of the aryepiglottic fold is an uncommon benign tumor. We report a rare case of a laryngeal schwannoma. The clinical, computed tomography (CT) and magnetic resonance imaging findings are presented. The tumor was located at the both aryepiglottic folds of the larynx. The CT scan revealed a well defined, delayed, heterogenously, target-like enhancing mass extending from the right aryepiglottic fold to the left aryepiglottic fold. The tumor was removed completely by laryngomicroscopic surgery (LMS). The diagnosis and treatment of this tumor are also discussed.

Glutaric Aciduria Type 1 in Korea: Report of Two Novel Mutations

박준동,임병찬,김기중,황용승,김승기,강성호,조성임,박성섭,이준수,채종희 대한의학회 2010 Journal of Korean medical science Vol.25 No.6

Glutaric aciduria type I (GA I) is an autosomal recessive disorder caused by a deficiency of glutaryl-CoA dehydrogenase. Although over 400 patients confirmed as GA I have been reported, reports from the Asian population had contributed to the minor proportion. We recently diagnosed two cases of GA I confirmed with mutational analysis. Here, we present their rather atypical clinical presentations with genetic characteristics for the first time in Korea. Profound developmental delay from birth, association of hearing loss, and neurological improvement after surgical intervention, were considered to be different clinical features from most reported cases. One patient was a compound heterozygote for p.Ser139Leu and p.Asp220Tyr, and the other for p.Ser139Leu and Glu160X. The mutations of the two alleles (p.Asp220Tyr and p.Glu160X) were novel and reports of p.Ser139Leu were rare both in Western and other Asian populations. These might suggest different genetic spectrum of Korean GA I patients.

소아청소년 환자 진료에서의 윤리적 고려

박준동 한국의료윤리학회 2015 한국의료윤리학회지 Vol.18 No.1

The rights of patient in the medicine is emphasized recently, especially the right to be appreciated and the right to get adequate information about the management. Self-determination with the informed consent is the most important factor in the decision. There are several limitations in the process of decision-making for medical treatment in the children. Children usually have not enough capacity for decision. But the children are constantly developing and they have different capacity for the decision on the stage of development. So, health care professionals should seek the best options to reflect the opinions of children in the decision-making. Consent of assent of the children should be based on the capacity of the children. All the decisions are should be for the best benefits of the children. If there are some debate on the decisions, health care professionals should consult to social worker or ask the discussion in th committee for medical ethics. 과거에 비해 진료 과정에서 환자 권리의 중요성이 점점 더 강조되고 있는데, 특히 환자로서 존중 받을 권리와 설명을 받고 이에 근거하여 스스로 선택할 수 있는 권리가 강조되고 있다. 설명 들은 내용에 근거하여 어떤 선택을 결정하는 데 있어 노인이나 소아, 의식이 없는 환자 등 특별한 상황에서는 스스로 판단할 수 있는 능력이 부족할 수 있다는 측면에서 몇 가지 문제점을 가지고 있다. 이런 환자의 진료 과정에서 어떤 선택을 해야 할 때 합리적인 결정을 위해서는 많은 점이 고려되어야 한다. 소아청소년은 점진적으로 발달하고 있다는 측면에서 선택 과정에서 환자의 결정권을 어떻게 존중할 수 있는지 고려되어야 할 많은 윤리적 문제가 있다. 소아는 자신의 건강과 관련하여 신중한 결정을 할 수 있는 능력과 자격을 갖추고 있다고 할 수 없다. 법률적으로도 미성년자는 독자적으로 유효한 법률행위를 할 수 없고, 법률행위를 하고자 한다면 원칙적으로 법정대리인의 동의를 얻어야 한다. 그러나 소아청소년은 육체적인 능력뿐만 아니라 지적 능력도 계속 성장하고 있다. 소아청소년의 진료와 관련해서 의사 결정과정의 동의 또는 허락이나 거부는 이런 능력의 성숙도를 감안하여 환자에게 가장 적합한 방법으로 접근해야 한다. 특히 보호자 등 환자와 관련된 여러 사람들의 선택이 서로 상충되는 경우에는 의료인은 보편적 윤리에 근거하여 환자의 최선의 이익을 위해 모든 것을 고려해야 하며 학대의 여부 등 의료인 개인의 판단만으로 결정을 내리기 민감한 부분은 사회사업가 등의 전문가에게 의뢰하거나 윤리위원회 상정 등의 법률적 조언을 구해야 한다.

The study examines whether the post-KR delay interval has an effect on motor learning. With 135 students as subjects, divided into age(9, 15, 21) and condition(5 sec, 10 sec, 30 sec), I gave them linear-positioning tasks. The following results were obtained in two stages of acquisition and transfer. 1. In Acquisition Stage, there appeared a significant difference at the levels of age(P<.001) and condition(P<.001). 2. No significance was shown in the interaction effect among the factors of age, condition and block. 3. Every age group in Acquisition Stage performed effectively in 5-sec condition than in other conditions. 4. Since both Acquisition Stage and Transfer Stage reveal different performance scores, the post-KR delay interval can not be regarded as a learning variant to simple tasks.
