Primary retroperitoneal mucinous cystadenocarcinoma is a very rare malignancy. To date, 51 cases have been reported, including 3 in pregnant women. Herein, we report magnetic resonance findings of a 31-year-old Korean woman (15 weeks and 3 days pregnant) with primary retroperitoneal mucinous cystadenocarcinoma. On abdominal magnetic resonance imaging (MRI), a mass was identified in the retroperitoneal area with a nodular lesion showing heterogeneous signal intensity and focal wall thickening on T1- and T2-weighted images. Exploratory laparotomy and tumor excision were performed. Histological examination revealed primary retroperitoneal mucinous cystadenocarcinoma. The patient subsequently underwent total hysterectomy, bilateral salpingo-oophorectomy, and omentectomy for metastatic mucinous cystadenocarcinoma of both ovaries 15 months after her initial surgery.

Background: Exit site/tunnel infection causes considerable morbidity and technique failure in CAPD patients. We presently use a unique revision method for the treatment of refractory ESI/TI in CAPD patients and mupirocin prophylaxis for high risk patients. Materials and Methods: We reviewed 139 CAPD patients about the ESI/TI from October 1993 to February 1999 at Yeungnam University Hospital. At the beginning of the ESI. we usually started medications with rifampicin and ciprofloxacin and then changed the antibiotics according to the sensitivity test. If the ESI had persisted and there were TI symptoms (purulent discharge, abscess lesion around exit site). we performed catheter revision(external cuff shaving, disinfection around tunnel and new exit site on opposit direction) with a combination of proper antibiotics. We applied local mupirocin ointment at the exit site three times per week to the 34 patients who had the risk of ESI starting from October 1998. Results: The total follow-up was 2401 patient months(pt. mon). ESI occurred on 105 occasions in 36 out of 139 patients, and peritonitis occurred on 112 occasions in 67 out of 139 patients. The total number of incidences of ESI and peritonitis was 1 per 23.0 pt. mon and 1 per 2l.6 pt.mon. The most common organism responsible for ESI was Staphylococcus aureus (26 of 54 isolated cases, 48%), followed by the Methicillin resistant S. aureus(MRSA) (13 cases, 24%). Seven patients(5: MRSA. 2: Pseudomonas) had to be treated with a revision to control infection. Three patients experienced ESI relapse after revision. One of them improved with antibiotics, while another needed a second revision and the remaining required catheter removal due to persistent MRSA infection with re-insertion at the same time. But, there was no more ESI in these 3 patients who were received management to relapse (The mean duration: 14.0 months). The rates of ESI were significantly reduced after using mupirocin than before(1 per 12.7 vs 34.0 pt.mon, P<0.01). Conclusions: In summary, revision technique can be regarded as an effective method for refractory ESI/TI before catheter removal. Also local mupirocin ointment can play a significant role in the prevention of ESI.

당뇨병은 전 세계적으로 급격하게 증가하면서 심각한 대혈관 및 미세 혈관 합병증들의 원인이 되고 있으며 대다수 선진국에서 당뇨병은 만성 신질환 및 말기 신부전의 가장 중요한 원인으로 알려져 있다. 당뇨병성 신증은 단백뇨를 특징으로 하며 30% 정도의 환자에서는 혈뇨도 관찰된다. 그래서 당뇨병성 신증의 발병 검진은 미세알부민뇨 검사로 하는 것이 가장 이상적이며 제 1형 당뇨병환자는 일반적으로 당뇨병 발병 5년 이후에 하며 위험인자가 있는 환자는 더 조기에 한다. 제 2형 당뇨병환자는 당뇨병 진단 시점부터 매년 하는 것을 원칙으로 한다.

Purpose : The aim of this study was to develop a quality of life scale for children on chronic peritoneal dialysis(QOL-CPD). Methods : Thirty children on chronic PD at Seoul National University Children's Hospital participated. A healthy control group included 47 elementary school children. Other patients groups are 32 children from the department of pediatric orthopedics and 28 children from the department of child psychiatry. The age range of all children was 7 to 16 years. Preliminary items of the QOL-CPD were developed and administered along with the Korean version of the Children's Depression Inventory(CDI) to all children. Results : The final QOL-CPD was constructed by excluding those items with a factor loading of less than .20, and the principal axis factor analysis was performed again. The QOLCPD demonstrated a good internal consistency with a value of .87. The dialysis and childpsychiatric groups showed significantly lower QOL scores compared to the healthy control group. In addition, the dialysis and child-psychiatric groups showed greater difficulties on physical and academic functions. For the CDI, the PD group showed a mild level of depression. Conclusion : The results of this study demonstrate the clinical utility of a newly developed self-report QOL scale specific for children on chronic PD.

목적 : 만성신부전환자에서 carumonam의 약동학적 특성을 검토하고, 동시에 투석에 의한 carumonam의 제거 양상을 분석하여 이들 환자에서 carumonam의 적절한 투여용량 및 용법을 고안하고자 하였다. 방법 : 혈액투석(HD) 또는 지속성 복막투석(CAPD)을 받고 있는 14명의 말기 신부전중 환자를 대상으로 하였다. HD환자에서는 carumonam 1 g을 20분간 지속정주하고 4시간 이후 혈액투석을 4 또는 5 시간 시행하였으며 투약 후 36시간까지 경시적으로 혈액 및 투석액을 채취하여 체액내 약물 농도를 측정하였다. CAPD환자는 1일 3회 (6.6, 12 시간) 투석액을 교환하는 환자를 대상으로 하였고 투석직후 carumonam 1g을 지속정주하고, 투약후 36시간 후까지 경시적으로 혈액 및 투석액을 채취하여 CAPD 환자에서 carumonam의 약동학적 특성을 검토하였다. 체내 동태는 HD의 경우 dialyser를 포함하는 2-compartmental model에 의한 분석을 시행하였고, CAPD를 시행받는 환자의 경우에는 체액과 투석액사이에 bidirectional clearance 개념을 도입한 모델을 이용하여 분석하였다.

Purpose: The aim of this study was to investigate the causes of under-staging in patients with advanced gastric cancer that was proven to be unresectable after a laparotomy. Materials and Methods: We retrospectively analyzed 25 gastric cancer patients who had undergone a diagnostic laparotomy between 2001 and 2005. For the preoperative evaluation, spiral CT and multidetector-row CT were performed. We analyzed the clinicopathologic features of patients and compared the image findings and the results of surgery. The causes of under-staging were divided into 3 groups; patient factor, CT factor, and interpretation factor. Results: Grossly, there were 12 cases of Borrmann type-III tumors and 13 cases of Borrmann type-IV tumors. The most frequent histologic type was poorly differentiated adenocarcinomas (8 cases) and signet ring cell carcinomas (7 cases). There were 13 cases of adjacent organ invasion, and the pancreas was the most frequently invaded organ (9 cases). There were 17 cases of peritoneal metastasis, and 3 cases of distant lymph node metastasis. For the cause of under-staging, there were four cases of patient factor, 19 cases of interpretation factor, and 9 cases of CT factor. In three cases, the cause of under-staging could not be identified. Conclusion: CT interpretation factor was the most frequent cause of under-staging in the preoperative diagnosis with gastric cancer patients. Therefore, more cautious CT interpretation is necessary to avoid unnecessary laparotomies in gastric cancer patients.

A 10-year-old spayed female Shih-tzu dog with a left-sided caudal abdominal swelling of 2-month clinical duration was referred to the Konkuk University Teaching Hospital (KUVTH). We confirmed the presence of an abdominal mass by radiography and ultrasongraphy. A gossypiboma was identified between bladder and small intestines at surgery and removed. The resulting peritoneal adhesion was severe. But, the peritoneal defect did not allow easy repair of the abdominal wall. Therefore, polypropylene mesh (PPM) was used in repair. The patient was good condition after surgery with no caudal abdominal swelling. We followed the patient for the next 6 months with no complication.

Paraganglioma is a neoplasm consisting of sympathetic neuroendocrine cells, which arise from neural ectoderm of extra-adrenal paraganglia. It often occurs in thyroid, carotid body, mediastinum, lung, duodenum, the retroperitoneal area and periaortic area. Malignant paraganglioma is defined not by the histological diagnosis, but by spread to regional lymph nodes or distant metastasis. Rare bone metastasis mostly occurs in the base of skull or spine, and even it rarely metastasizes to pelvis or femur. We would like to report two cases of paraganglioma; one in the subcutaneous fat layer that was mistaken for a vascular tumor, and the other in the retroperitoneal space with early bone metastasis.

위암의 진단에서 CT스캔은 수술 전 병기결정이나 수술 후 추적검사에서 필수적인 검사방법으로 인정을 받고 있고, 보편적으로 가장 많이 유용되고 있다. 그러나 나선식 CT를 사용하고 여러 가지 스캔방법의 개선에도 불구하고, 인접장기로의 직접침윤, 작은 크기의 간전이의 발견, 정상 크기범위의 림프절에서 전이의 발견, 양성 림프절과 전이의 감별, 복막전이에 대한 평가에서 지금까지의 보고들은 만족스러운 결과를 얻지 못하고 있으며 CT의 한계점으로 남아 있다. 그러나 최근에는 나선식 CT보다 더 빠른 시간내 더 얇은 두께의 절편을 얻을 수 있고, 이를 이용하여 관상면 및 시상면으로 정밀하게 재구성하거나 3D영상을 얻을 수 있는 다검출식 나선식 CT가 개발되어 사용되고 있고, CT 진단의 정확도를 높일 것으로 기대한다.
