OBJECTIVE: The purpose of this study was to evaluate the chest radiographic and CT findings of novel influenza A (H1N1) virus infection in children, the population that is more vulnerable to respiratory infection than adults. MATERIALS AND METHODS: The study population comprised 410 children who were diagnosed with an H1N1 infection from August 24, 2009 to November 11, 2009 and underwent chest radiography at Dankook University Hospital in Korea. Six of these patients also underwent chest CT. The

Objectives To present the radiological and clinical results of transcatheter arterial embolization in patients with active bleeding after percutaneous renal procedures. Methods A total of 79 consecutive patients who underwent angiography for percutaneous renal procedure‐related bleeding were included in the present retrospective analysis. Patient characteristics, angiographic management and clinical outcomes were analyzed. Results On angiography, bleeding foci were observed in 81.0% of the patie

Although renal angiomyolipoma (AML) is a benign tumor, treatment may be necessary occasionally because it can cause potentially life-threatening retroperitoneal hemorrhage. Transarterial embolization (TAE) is a safe and effective treatment option to prevent the hemorrhagic rupture of AMLs and relieve the symptoms caused by enlarged lesions or active bleeding. However, there is no clear consensus regarding the indications for prophylactic TAE in patients with sporadic renal AMLs. In urgent TAE fo

Cerebral salt wasting is characterized by inappropriate natriuresis and volume contraction with associated cerebral pathology. It is distinct from the syndrome of inappropriate antidiuretic hormone secretion, which is characterized by inappropriate retention of free water. We report a patient with a porencephalic cyst who developed cerebral salt wasting. His initial treatment was supplementation of water and salt, which did not improve natriuresis or volume contraction. Fludrocortisone administr

The incidence of uterine arteriovenous malformation (AVM) is rare. However, it is clinically significant in that it can cause life-threatening vaginal bleeding. We report a case of a large uterine AVM with positive serum beta-human chorionic gonadotropin. A presumptive diagnosis was made; a uterine AVM accompanied by, early pregnancy or retained product of conception. Because this uterine AVM was extensive, transcatheter arterial embolization of both uterine arteries and extra-uterine feeding ar

Pulmonary artery pseudoaneurysms (PAPs) are rare and can occasionally be overlooked as a cause of hemoptysis. The rupture of PAPs may lead to severe and massive hemoptysis and asphyxiation, necessitating prompt and accurate diagnostic measures, including CT angiography, in conjunction with clinical awareness for adequate management. The aim of this pictorial essay is to establish a strategy for endovascular intervention based on a comprehensive understanding of the etiology and hemodynamics of b

TAE is an effective and a safe treatment method for controlling secondary PPH regardless of angiographic findings.

Gastrointestinal stromal tumors (GISTs) are not uncommon and often cause gastrointestinal bleeding. GISTs occurring in the small intestine are occasionally difficult to identify by endoscopy and CT. In this case, the patient underwent CT three times before surgery, and the lesion was found to be located in a different area of the abdominal cavity on each CT scan. Moreover, the lesion was missed in the first two CT images because it was difficult to distinguish it from the nearby collapsed small

본 논문은 협대역의 플라즈모닉 흡수체 구현을 위한 금속 나노입자 주기구조 설계 및 제작에 관한 연구다. 제안된 플라즈모닉흡수체의 상단 금속 나노입자는 주기적으로 홈이 파여있는 템플릿을 이용하여 전자빔 증착 후, 열처리하는 제작 기술로 형성하였다. 주기적 홈 템플릿 위에 제작된 금속 나노입자를, 따로 제작한 33 nm 두께의 Al2O3가 스퍼터 가공된 200 nm 두께의 금속반사판-기판 상단에 옮기는 방법을 통해 플라즈모닉 흡수체를 제작하였다. 제작된 금속 나노입자는 평균 지름 46 nm, 주기 76 nm의크기를 가졌다. 광학 측정 결과, 제작된 플라즈모닉 흡수체는 중심파장 572 nm, 반값전폭 109.9 nm의 플라즈모닉 공명 흡수를나타내었다.

2021년 8월에 섬진강 수계인 전라북도 임실군 신평면 덕암리와 경상남도 하동군 고정면 대덕리에 서식하는 육봉형과 양측회유성 은어의 후각기관의 형태와 조직학적 특징을 확인하기 위해 실체현미경, 광학현미경, 주사전자현미경을 이용하였다. 그 결과, 두 유형의 은어의 외부 형태는 유사하였으며 타원형의 전비공, 반원형의 전비공과 비경계판이 한 쌍을 이루었다. 20~22개의 후판이 로제트 구조를 형성하였으며 이차 주름이 후판의 표면에서 확인되었다. 조직학적 결과에서도 두 유형은 서로 유사하였다. 감각상피는 연속분포 유형이었으며 후감각뉴런, 지지세포, 기저세포, 섬모, 미확인 세포가 확인되었으며 비감각상피에서는 편평상피세포, 기저세포, 점액세포가 확인되었다. 본 연구에서 육봉형 은어와 양측회유성 은어의 해부·조직학적 차이는 확인할 수 없었으나 다른 소하성 어류보다 많은 후판의 개수와 이차 주름의 존재로 인해 다른 소하성 어류보다 후각 민감도가 높을 것으로 사료된다.
