신성 고혈압은 소아기 이차성 고혈압의 흔한 원인이며, 그 중 신동맥 협착에 의한 신혈관성 고혈압은 치료 가능한 고혈압의 가장 흔한 원인이다. 신혈관성 고혈압 치료로 최근 경피적 신동맥 혈관 성형술은 비침습적인 방법으로 각광 받고 있다. 저자들은 작은 직경을 가진 신동맥 분지 혈관 협착에 의한 신혈관성 고혈압 소아에서 관상동맥용으로 쓰이는 풍선 카테터를 이용하여 경피적 신동맥혈관 성형술을 성공적으로 시행한 경험을 하였으므로 보고하는 바이다.

Although Dieulafoy lesion can occur in any part of the gastrointestinal tract, its occurrence in the rectum is rare. Rectal Dieulafoy lesions have been associated with advanced age, renal failure, burns, liver transplantation and cirrhosis. Here, we report on a case of massive bleeding from a rectal Dieulafoy lesion after lung decortication surgery in a 57-year-old male patient with alcoholic cirrhosis. Although rare, a rectal Dieulafoy lesion should be included in the differential diagnosis of massive lower gastrointestinal bleeding in a patient with cirrhosis.

Angiodysplasia is the most common vascular abnormality of the gastrointestinal tract and probably the most frequent cause of recurrent lower intestinal bleeding in otherwise healthy elderly patients. Also, it is an important cause of hemorrhage in chronic renal failure observed in up to 19~32% of patients. Bleeding due to gastric angiodysplasia is treated by various endoscopic approaches, including argon and Nd : YAG laser photocoagulation, monopolar or bipolar electrocoagulation, heater probe, injection sclerotherapy, band ligation or hemoclipping. A 15-year-old boy, who had undergone hemodialysis for chronic renal failure for about 10 years, was admitted due to melena and progressive anemia. A gastroduodenoscopy revealed a cherry red and fern-like lesion with oozing on the posterior wall at junction of gastric body and fundus. Endoscopic hemoclipping therapy was performed. However, melena recurred four days later. Argon plasma coagulation and hemoclipping therapy were performed again. Since then, no recurrence of bleeding has been observed.

Obesity-related glomerulopathy (ORG)는 단백뇨를 보이는 비만아에서 신장 조직학적 소견상 사구체 비대, 국소 분절성 사구체 경화 소견이 관찰되고 기저막 비후, 국소 간질조직 증식, 중등도의 발 돌기 소실 등을 보이는 질환으로 정의된다. 특발성 국소분절 사구체경화증과 비교하여 신증후군이 적으며 콜레스테롤 상승이 적고, 병의 진행이 느리다는 점에서 차이가 있다고 알려져 있으며, 체중감소를 통해 신장 기능이 회복될 수 있다고 알려져 있다. 본 증례의 9세된 비만아는 임상증상과 신장 조직검사에서 ORG로 진단되어 치료하였으나, 지속적인 체중 증가와 단백뇨로 말기 신부전으로 진행하여 소아 ORG 환아에서는 드문 경과를 취하여 이를 보고하는 바이다.

A 13-year-old male Yorkshire terrier was Presented with Persistent weight loss anorexia and dark brown urine of 3-month duration. On physical examination, a firm oval mass was palpated at left renal region. In hematology and blood chemistry, neutrophilia, anemia, thrombocytopenia and elevation of ALKP were found. Abdominal radiography, ultrasonography and ultrasound-guided percutaneous pyelogram revealed masses originated from left kidney, mildly dilated renal Pelvis and intact ureter. Urinalysis showed hematuria and proteinuria. Because the state of dog became deteriorated during transfusion and the frail renal tumor was suspected to be the cause of inflammation and anemia, nephrectomy was performed. Renal masses, approximately $2{\times}3cm\;and\;5{\times}4cm$ respectively in size, was surrounded by swollen and congested mesentery and ascites. Metastatic lesion was not found in other organs. During recovery, the dog showed cardiopulmonary arrest and did not respond to critical care. Histologically the kidney was affected by necrotic and hemorrhagic change. This hemangiosarcoma most likely arose from the renal parenchyma resulting In diffuse lesions in the kidneys thought to be the cause of chronic anorexia and weight loss.

신장의 기능을 정량분석 할 수 있는 $^{99m}Tc$-DMSA 평면 영상은 단층영상에 비해 병소의 위치 정보에 한계가 있다. 따라서 광자 신호에 민감한 범용성 collimator로 교체하여 SPECT 방식으로 임상실험을 시행한 후, 진단의 정확도와 검사 소요시간을 분석하여 임상적용 가능성을 평가하였다. 10명의 실험대상에게 방사성의약품(1.0-1.2 MBq/kg)을 정맥주사하고, 이중 검출기 감마카메라를 이용하여 planar scan (high resolution (HR)-mode, $256{\times}256$, 50 kcts/view, 4 image)과 SPECT (HR / high sensitive (HS)-mode, $128{\times}128$, step and shoot, $180^{\circ}$, variable sec/angle, total 64 frame, OSEM reconstruction)를 시행하였다. 획득한 데이터를 분석 프로그램을 이용하여 비교한 결과, 실험 방법에 따라서 total counts는 high sensitive-mode SPECT가 대략 1.8-5.6 배 정도 많았고, counts를 이용한 상대신장기능은 모든 실험에서 유의한 수준 범위에서 차이가 없었으며(p=0.96), 검사 소요시간은 39%정도 단축되었다. 그러므로 고감도 범용성 collimator를 이용한 $^{99m}Tc$-DMSA renal SPECT는 planar scan에 비하여 신장의 기능을 정량분석 할 수 있고, 병변의 위치에 대한 정보를 보다 정확하게 진단할 수 있으며, 동시에 검사 소요시간을 단축시킬 수 있으므로 임상적으로 유용하게 활용할 수 있을 것으로 사료된다.

RO는 경계가 좋은 고형종괴로써, 석회화를 포함할 수 있다. 조영전 CT 영상에서 신실질과 유사한 밀도의 균일한 종괴로 보인다. 조영 후 영상에서는 불균일하게 조영증강되는데, 역동적 조영증강 검사의 동맥강조기에서 주변부는 강하게 조영증강되었다가 시간에 따라 점차 조영이 약해지고, 중앙부는 시간에 따라 점차 조영이 증강되어 시간에 따른 조영증강의 부분적 역전현상이 관찰되었다. 이러한 영상의학적 특징이 관찰되는 경우에는 RO의 가능성을 시사할 수 있으며 이를 통해 환자의 예후를 예측하고 수술 방법을 술전에 결정하는데 도움을 줄 수 있으리라 생각한다.

Kimura disease is a chronic benign disorder, primarily seen in asians male during the second and third decades of life, which presents itself as a tumour like lesion with a predilection for the head and neck region. There is high prevalence of associated renal disease. We report two cases of nephrotic syndrome associated with Kimura disease, and this is the first report of Kimura disease with renal involvement in Korean children.

Hypothermia and circulatory arrest is efficatious adjunct in the surgical treatment of conventionally difficult or otherwise inoperable lesion. This technique was utilized in 5 patients, 3 with membraneous obstruction of inferior vena cava[MOVC] and 1 with giant middle cerebral artery aneurysm and 1 with renal cell carcinoma invading inferior vena cava. All membraneous obstruction of inferior vena cava patients had excellent results but the others died of operative complications. The rationale for the use of complete cardiac arrest with hypothermia is reviewed and the use of these technique in selected patients is warrented.

The authors treated a 58-year old female patient who had come to the Department of Oral Medicine, KNUH due to the chief complaints of gingival enlargement and bleeding on the upper and lower jaw. The lesions were diagnosed as cyclosporin-A induced gingival enlargement by patient's history and clinical examination. The patient was treated with gingivectomy using pulsed Nd:YAG laser. After gingivectomy the wound was compressed with 0.1% chlorhexidine-soaked gauze to prevent relapse of the lesion. Good healing process was observed and there were no recurrences until 3-month follow-up visit. From the results of this clinical trial it was suggested that a pulsed Nd:YAG laser gingivectomy would be helpful for the treatment of cyclosporin-A induced gingival enlargement in renal transplant patients.
