간결핵은 주로 폐결핵이나 속립성 결핵에 동반된 형태로 나타난다. 다른 부위에 결핵 감염 없이 일차성으로 간결핵으로 발현하는 경우는 드물다. 간 내 담관암 양상으로 보이는 간 종괴를 주소로 내원한 31세 남자의 증례이다. 복부 초음파, 전산화 단층 촬영, 자기공명영상, 양전자 단층 촬영에서 악성 종양을 의심할 만한 소견을 보이고 있었다. 복부 초음파를 이용한 조직 검사에서 진단이 불분명하여 내시경 초음파 검사와 내시경 초음파 세침흡인생검을 이용하여 간문부 결핵성 육아종을 진단한 증례이다. Hepatic tuberculosis is usually associated with active pulmonary or miliary tuberculosis. The occurrence of an isolated hepatic mass-forming tuberculosis with no evidence of tuberculosis elsewhere is rare. We report a case of a 31-year-old male with a solitary hepatic granuloma mimicking a mass-forming intrahepatic cholangiocarcinoma. Ultrasonography, computed tomography, magnetic resonance imaging, and positron emission tomography of the abdomen showed a malignant tumor-like lesion. We then conducted endoscopic ultrasonography (EUS) and EUS-guided fine-needle aspiration (EUS-FNA) for confirmation of the hepatic hilar mass, which was found to be a hepatic tuberculosis granuloma as the final diagnosis.

본 연구는 편측 노치가 삽입된 A16061-T6 알루미늄 합금 평판 시편에 대해 유리섬유강화플라스틱(GFRP) 복합재 패치의 적층수를 변수로 하여 보수하고, 인장 하중에 따른 시편의 손상 과정을 음향방출법(acoustic emission, AE)으로 실시간 분석하였다. AE 에너지 발생률(AE energy rate), hit 발생률(hit rate), AE 진폭(AE amplitud) 거동과 파형 및 1차 중심주파수(1st peak frequency)의 대역을 조사하여, 시편 파괴시 알루미늄 크랙(Al cracking), 섬유 파단(fiber breakage), 수지 균열(resin cracking), 층간 분리(delamination)로 분류하였다. 시편의 변위를 음향방출 특성에 따라 구간(region) Ⅰ, Ⅱ, Ⅲ으로 나눌 수 있었으며, 패치 자체가 실제 파괴되는 구간인 구간 Ⅱ를 세부적으로 분석하여 패치의 적층수에 따른 AE 특성 차이를 구하였다. Edge notched A16061-T6 aluminum was repaired with a GFRP composite patch as a function of the number of stacking. Damage progress of specimen for tension load has been monitored by acoustic emission(AE). AE energy rate, hit rate, amplitude, waveform and 1st peak frequency distribution were analyzed. Fracture processes were classified into Al cracking, Fiber breakage, Resin cracking and Delamination. Displacement of a specimen can be divided into Region Ⅰ, Ⅱ and Ⅲ according to acoustic emission characteristics. Region Ⅱ where the patch itself was actually fractured was focused on to clarify the AE characteristics difference for the number of stacking.

Systemic sclerosis is an autoimmune disease, characterized by inflammation, microangiopathy and fibrosis in the skin and various intestinal organs. Gastrointestinal involvement is one of the major causes of serious morbidity, and next to the skin, the gastrointestinal tract is the most commonly involved organ. While esophageal involvement is most common gastrointestinal manifestation, the involvement of the small intestine and colon is less common but may lead to life-threatening complications like chronic pesudoobstruction or pneumatosis cystoids intestinalis. Here, we describe a case of progressive systemic sclerosis associated with intestinal pseudoobstruction. 28 year-old male presented abdominal pain and vomiting and he was diagnosed as having intestinal pseudoobstruction. His symptoms were well managed using the combination of octreotide, a long-acting somatostatin analogue, and erythromycin.

저자들은 간질 발작 후에 동시에 발생한 미만성 폐포 출혈과 안면경흉부 자반증 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. A 40-year-old woman presented with hemoptysis and thoracocervicofacial purpura that occurred after a generalized tonic-clonic seizure. Diffuse alveolar hemorrhage is reported relatively rarely in neurogenic pulmonary edema (NPE), which is a life-threatening postictal complication. This clinical setting causes difficulty in the diagnosis, when an accurate diagnosis and proper management are required. Thoracocervicofacial purpura has been described as an unusual setting for an epileptic seizure. Here, we report the first case of postictal diffuse alveolar hemorrhage with thoracocervicofacial purpura. (Korean J Med 75:723-727, 2008)

Scrotal edema may develop during continuous ambulatory peritoneal dialysis (CAPD). The two etiologic mechanisms are peritoneo-scrotal communication through a patent processus vaginalis or extravasation of dialysate through a defect of abdominal wall. We report two cases of scrotal edema due to inguinal hernia by peritoneo-scrotal communication during CAPD. The etiology of scrotal edema was confirmed by peritoneal scintigraphy and/or computed tomography. Scrotal edema due to inguinal hernia was completely resolved by a surgical repair of hernia and did not recur despite of resumption of peritoneal dialysis.

Cytomegalovirus (CMV) infections are usually diagnosed in immunocompromised patients. A 74-year-old male without any significant medical history visited our center because of abdominal pain and diarrhea which began about a month ago. Abdominal computed tomography revealed segmental enhanced bowel wall thickening on jejunum and single-balloon enteroscopy showed multiple geographic shaped ulcerations covered with exudates on proximal jejunum. Biopsy samples taken during endoscopic examination demonstrated necrotic fibrinopurulent tissue debris and benign ulcer. Nested-PCR analysis of CMV DNA from jejunal tissue was positive. The patient was finally diagnosed with CMV jejunitis and was treated by intravenous ganciclovir for 14 days after which, abdominal pain and diarrhea improved. Our case shows that CMV jejunitis can occur in an immunocompetent adult as multiple jejunal ulcers which can be diagnosed using a single-balloon enteroscope. (Korean J Gastroenterol 2013;62:238-242)
