Membranous lipodystrophy is a peculiar type of fat necrosis, present in patients with various types of skin diseases. It is charaeterized by the presence of microcysts and macrocysts lined by amorphous eosinophilic material with a crenelated arabesque appearance and microgranules in the subcutis with massive fat necrosis. The eosinophilic lining and microgranules stain positively with periodic acid-Schiff, are resistant to diastase, and also stain with Sudan black B. We report three cases of subcutanous membranous lipodystrophy in patients with erythema induratum, posttraumatic panniculitis and morphea with typical clinical and histopathologic findings.

PURPOSE: The objective of this study was to assess the clinical outcomes of pelvic exenteration for patients with primary locally advanced colorectal cancer (LACRC) or locally recurrent colorectal cancer (LRCRC), and to identify clinically relevant prognostic factors. METHODS: Between January 2001 and December 2010, 40 consecutive patients with primary LACRC or LRCRC underwent pelvic exenteration at the National Cancer Center, Republic of Korea. We retrospectively reviewed their medical records. RESULTS: The median age was 59 years and the median follow-up time was 26 months (range, 1-117 months). The overall complication and in-hospital mortality rates were 70% (28/40) and 7.5% (3/40), respectively. The complication rates were similar between patients with primary LACRC (69.6%) and those with LRCRC (70.6%). The overall recurrence rate was 50% (17/34), and was lower in patients with primary LACRC than in patients with LRCRC (33.3% vs. 76.9%, P = 0.032). The 5-year overall survival was significantly different between primary LACRC and patients with LRCRC (58.7% vs. 11.8%, P = 0.022). Multivariate analysis revealed that radicality (R0 vs. R1/R2) was an independent prognostic factor for overall survival (P = 0.020). CONCLUSION: The complication and operative mortality rates of pelvic exenteration remained high, but pelvic exenteration might provide an opportunity for long-term survival and good local control. Complete (R0) resection was the only independent prognostic factor for overall survival.

PURPOSE: We evaluated the effect of human parathyroid hormone (hPTH) on the engraftment and/or in vivo expansion of hematopoietic stem cells in an umbilical cord blood (UCB)-xenotransplantation model. In addition, we assessed its effect on the expression of cell adhesion molecules. MATERIALS AND METHODS: Female NOD/SCID mice received sublethal total body irradiation with a single dose of 250 cGy. Eighteen to 24 hours after irradiation, 1x107 human UCB-derived mononuclear cells (MNCs) and 5x106 human UCB-derived mesenchymal stem cells (MSCs) were infused via the tail vein. Mice were randomly divided into three groups: Group 1 mice received MNCs only, Group 2 received MNCs only and were then treated with hPTH, Group 3 mice received MNCs and MSCs, and were treated with hPTH. RESULTS: Engraftment was achieved in all the mice. Bone marrow cellularity was approximately 20% in Group 1, but 70-80% in the hPTH treated groups. Transplantation of MNCs together with MSCs had no additional effect on bone marrow cellularity. However, the proportion of human CD13 and CD33 myeloid progenitor cells was higher in Group 3, while the proportion of human CD34 did not differ significantly between the three groups. The proportion of CXCR4 cells in Group 3 was larger than in Groups 1 and 2 but without statistical significance. CONCLUSION: We have demonstrated a positive effect of hPTH on stem cell proliferation and a possible synergistic effect of MSCs and hPTH on the proportion of human hematopoietic progenitor cells, in a xenotransplantation model. Clinical trials of the use of hPTH after stem cell transplantation should be considered.

PURPOSE: The use of 18F-2-deoxy-2-fluoro-D-glucose positron emission tomography-computed tomography as a routine preoperative modality is increasing for gastric cancer despite controversy with its usefulness in preoperative staging. In this study we aimed to determine the usefulness of preoperative positron emission tomography-computed tomography scans for staging of gastric cancer. MATERIALS AND METHODS: We retrospectively analyzed 396 patients' positron emission tomography-computed tomography scans acquired for preoperative staging from January to December 2009. RESULTS: The sensitivity of positron emission tomography-computed tomography for detecting early gastric cancer was 20.7% and it was 74.2% for advanced gastric cancer. The size of the primary tumor was correlated with sensitivity, and there was a positive correlation between T stage and sensitivity. For regional lymph node metastasis, the sensitivity and specificity of the positron emission tomography-computed tomography were 30.7% and 94.7%, respectively. There was no correlation between T stage and maximum standardized uptake value or between tumor markers and maximum standardized uptake value. Fluorodeoxyglucose uptake was detected by positron emission tomography-computed tomography in 24 lesions other than the primary tumors. Among them, nine cases were found to be malignant, including double primary cancers and metastatic cancers. Only two cases were detected purely by positron emission tomography-computed tomography. CONCLUSIONS: Positron emission tomography-computed tomography could be useful in detecting metastasis or another primary cancer for preoperative staging in gastric cancer patients, but not for T or N staging. More prospective studies are needed to determine whether positron emission tomography-computed tomography scans should be considered a routine preoperative imaging modality.

Granular cell tumors (GCT) are uncommon benign neoplasms. Their location is mostly in the the skin, tongue, and breast; appearance in other parts of the body is rare, but it has been reported. They have also been reported to occur synchronously in multiple organs and metachronously in a single organ. The incidence of GCTs in the tracheobronchial tree is unknown and pulmonary GCTs are uncommon, with approximately 100 reported cases in the literature. We present the case of a 33-year-old man with a granular cell tumor of the left main bronchus. The tumor was found at bronchoscopy performed to exclude suspected endobronchial mass with symptoms of pneumonia. Biopsies revealed the histological pattern of a benign granular cell tumor. He underwent resection of the left main bronchus followed by end to end anastomosis of left main bronchus. He has not had any recurrence of the tumor during the 1 year follow-up.

Primary pulmonary angiosarcomas are extremely rare tumors. The diagnosis is often delayed due to nonspecific symptoms, mimicking pulmonary embolism and require careful clinical evaluation to exclude metastasis from the heart, pericardium, and distant extrathoracic sites. Most diagnosis are made postmortem. We report a case of primary pulmonary angiosarcoma histopathologically confirmed postoperatively, which was clinically suspected endobronchial carcinoma with endobronchial obstruction with relavant literature review.

Swyer-James syndrome is a rare disease with patients presenting with unilateral hyperlucent lungs and hypoperfusion due to hypoplasia of the pulmonary artery and bronchiolitis obliterans. A unilateral hyperlucent lung generally develops after a lower respiratory tract infection during early childhood. In extremely rare cases, an association of bronchogenic carcinoma with Swyer-James syndrome has been reported. We report a case of bronchogenic squamous cell carcinoma associated with Swyer-James syndrome that performed right upper lobectomy and lymph node dissection with a relevant literature review.

Acardiac fetus in triplet pregnancy is a very rare, fatal congenital anomaly that had not been reported in Korea. It only occurs in multiple gestations associated with placental vascular anastomoses between the affected fetus and its co-twin. The major complications associated with acardiac fetus in triplet pregnancy are congestive heart failure in normal pumping fetus, maternal polyhydramnios, preterm labor, intrauterine fetal death, etc, and perinatal diagnosis can be made with the perinatal ultrasonographic examination. We report a case of acardiac fetus in a spontaneous triplet pregnancy at 23 weeks of gestational age with a brief review of the literature.

OBJECTIVE: HL7(Health Level 7) develops standards for the representation of clinical documents like discharge and consultation notes. The goal of the present study is to develop XML(eXtensible Markup Language)-based communication standard for discharge note. METHODS: This paper presents the use of XML for electronic communication in a document-based EMR, first, as a format for the exchange of structured message, and second, as a comprehensible way to represent patient document. A retrospective analysis of 1165 discharge notes, from the department Seoul National University Hospital, were extracted by querying OCS(Order Communication System) and taking every discharge note of main disease issued over one year period (2003.01.01~2003.12.31). RESULTS: An XML-based prototype for discharge note has been put into place representing the required "section" and "specific instance". In addition, a subset of the CDA(Clinical Document Architecture) Level One details has been described and integrated. CONCLUSION: Through the introduction of definitions for sections and specific instances, progress in the development of CDA Level Two and Three might be realized. An XML-based prototype was implemented, allowing a special view on XML data to generate this document type.
