Pancreatic cystadenoma is very rare, slow growing tumor and generally preoperative differential diagnosis may be difficult. A 43-year-old female was admitted to our hospital with the complaint of abdominal discomfort in the epigastrium for about preceeding 5 years. Ultrasonography and Computed tomography were performed. When endoscopic retrograde cholangio-pancreatogram was performed, displacement of distal pancreatic duct by huge mass was noted and injected dye was drained irregulary into the cavity of mass. Distal pancreatectomy was performed with splenectomy. The mass size of distal pancreas was 7X4cm, and the cyst contained with yellowish thick mucoid fluid. Diagnosis was confirmed the mutinous cystadenoma of the pancreas on histologic examination.

목적 : 3년간 서울시 강서지역의 1개 대학병원에서 입원치료를 받은 성인 급성 신우신염 환자를 대상으로 원인균과 항생제 감수성을 조사하고, 향후 급성 신우신염의 초기 경험적 치료 항생제를 제안하고자 하였다. 방법 : 1999년 1월부터 2001년 12월까지 3년간 고려대학교 의과대학 구로병원에 상부요로감염으로 내원한 16세 이상 환자 229명의 의무 기록을 검토를 통하여, 인구학적 특성, 원인균, 항생제 감수성, 초기 항생제 사용 양상과 입원기간을 조사하였다. 결과 : 연구에 포함된 229명을 118명의 단순 신우신염군과 111명의 복잡 신우신염군으로 구분 하였다. 단수 신우신염의 평균 발생 연령은 38.2세와 복잡 신우신염 56.1세로 복잡 신우신염 환자의 연령이 유의하게 높았다(P<0.001). 양군 모두에서 원인균 중 E. coli의 분리율이 가장 높았으며 항생제 감수성 결과 ampicillin, trimethoprim-sulfame-thoxazole에는 높은 내성률을 보였고, ciprofloxacin, gentamicin, cefotaxime에 대한 감수성은 비교적 높았으나 복잡 신우신염의 경우 단순 신우신염에 비하여 ciprofloxacin, gentamicin에 대한 감수성이 다소 낮은 것을 확인할 수 있었다. 평균 입원 기간, 항생제 투여 기간에 있어서도 복잡 신우신염군에서 유의하게 길었다. 결과 : 본 연구의 결과 서울의 강서 지역에서 대학병원급에 치료 의뢰되는 단순 급성 신우신염의 치료에 있어 1차 항생제로 3세대 cephalosporin, aminoglycoside, quinolone 중 한가지를 초기 경험적 치료제로 사용을 고려하여야 할 것으로 사료된다. Background : The purpose of this study is to recommend the initial therapeutic regimen for adult patients with acute pyelonephritis (APN) according to the changes of antimicrobial susceptibility patterns of causative microorganisms isolated from patients with APN. Methods : We reviewed medical charts of 229 APN patients, who had been treated at Korea University Guro Hospital from 1st of January. 1999 to 31st of December, 2001. We investigated the demographic data, clinical findings, durations of hospital treatment, antimicrobial susceptibility patterns of the causative microorganisms and initial antibiotic regimens in patients with APN. Results : In this study, 229 adult patients with APN were classified into simple APN patients (118 patients, 51.5%) and complicated APN patients (111 patients, 48.4%). Mean age of patients with simple APN was 38.2±14.1 years old and that of patients with complicated APN was 56.1±14.9 years old. Mean age of patients with complicated APN was significantly higher than that of simple APN patients (P<0.0001). Escherichia coli was the most common microorganism both in simple APN (96.7%) group and in complicated APN (90.6%) group. Antimicrobial susceptibility of E. coli was at the low level of ampicillin (31%/20%) and trimethoprim-sulfamethoxazole (42.6%/34.2%) in each group. In contrast, ciprofloxacin (11.5%/22.7%), gentamicin (16.4%/22%) and cefotaxime (0%/8.2%) resistance remained at relatively lower level. In comparison of simple APN with complicated APN, ciprofloxacin and gentamicin resistances were higher in complicted APN group. Average duration of hospitalization (5.9±2.3 days/8.2±4.6 days) and duration of antibiotic use (12.1±3.9 days/15.3±10.0 days) were significantly longer in complicated APN. Conclusions: The results of this study suggests that 3rd cephalosporin, aminoglycoside or quinolone antibiotic would considered as one of the initial therapeutic regimen for patients with simple APN in southwestern Seoul.

Serious disease due to Toxoplasma gondii occurs in congenitally infected children and in immunosuppressed patients, particularly in the case of HIV infection. Glycoproteins modulate the physicochemical properties, and are involved in biological and immunological activities. Although there are many reports about the immune responses after T. gondii infection, there are few reports to identify the glycoproteins from T. gondii. For this reason, we purified the glycoproteins from tachyzoites and cysts of T. gondi and then evaluated the antigenic characterizations of toxoplasmic glycoproteins. Tachyzoites of T. gonii were purified by Percoll-gradient centrifugation. Glucosamine was the major monosaccharides released from the tachyzoites of T. gondii by acid hydrolysis methods. In order to define the antigenicities of both strains, we did 2-dimensional electrophoresis(2-DE). Over 40 protein spots were reproducibly separated in tachyzoites of T. gondii by 2-DE in range of the pH 5-8. Glycoproteins were isolated from tachyzoites of T gondii by Con A-Sepharose 4B affinity chromatography. The major bands of glycoproteins were approximately 22 kDa, 30 kDa and 38 kDa in tachyzoites of T. gondii.

An unconscious 20 year old male carried into the emergency department after an electric shock injury 20 minutes earlier. Cardiopulmonary resuscitation was undertaken when asystole appeared on the electrocardiograph monitor. A 12-lead electrocardiograph was taken when in that myocardial infarction was found after performing cardiopulmonary resuscitation on an electrical injury patient. We present out case's electrocardiographs with echocardio-graphic findings and radionuclide imaging studies.

저자들은 장결핵 중 발생 부위상 드문 곳으로 알려진 직장에 발생한 고림성 결핵을 3예 경험하였기에 문헌고찰과 함께 보고하는 바이다. Isolated rectal tuberculosis commonly involves sigmoid, ascending, or transverse colon. Rectal involvement in tuberculosis is uncommon and poorly characterized. Isolated rectal tuberculosis was defined as focal lesions of rectum in the abscence of demonstrable lesions in the small and large bowel. Diagnosis of rectal tuberculosis was based on characteristic endoscopic appearance of lesions, histopathologic feature of tuberculosis in biopsy material and response to antitubercular therapy. Three patients with isolated rectal tuberculosis were seen at Kwak's hospital. The lesions observed was classified according to macroscopic morphology as follows: ulcerative, hypertrophic and ulcero-hypertrophic. Clinical manifestations were non-specific and consists of rectal bleeding, fever, weight loss, constipation and abdominal pain. One of the three patients had coexisting tuberculous pleurisy. Response to antitubercular chemotherapy was good. (Koeran J Med 64:96-100, 2003)

Case report of a pancreatic squamoid cyst

Squamoid cyst of the pancreas is a very rare disease and it has been proposed only recently as a distinct pathologic lesion. We herein present a case of pancreatic squamoid cyst in a patient who underwent laparoscopic resection. A 60-year-old woman had an abdominal computed tomography (CT) scan for a routine check-up, and a multi-cystic lesion of 1.8-cm in size was incidentally found in the tail of the pancreas. Biochemical laboratory tests were within normal limits. At first, we presumed that the most likely diagnosis of the cystic lesion was an intraductal papillary mucinous neoplasm. To treat this lesion, we performed laparoscopic spleen-saving distal pancreatectomy. The patient showed the usual routine postoperative course and she was discharged 10 days after surgery. On examination of the resected specimen, a well-defined, oligolocular cystic mass was found in the pancreatic tail, without a solid portion. Histologic examination revealed that the cysts had linings ranging from flat squamoid cells to transitional cells with non-keratinization. After immunohistochemical staining, the final diagnosis was confirmed to be squamoid cyst of the pancreas. This lesion appears to be regarded as a benign entity, thus an extended operation should be avoided and resection of the lesion can be performed minimally.
