In evaluating the early state of shock patients and their response to treatment, generally vital signs or additional hemodynamic values were used. Vital signs are easily obtained and repetitious values or continous monitoring is possible, whereas it cannot evaluate the patient's status properly nor is it a good prognostic factor. Meanwhile, additional hemodynamic values are obtained from pulmonary artery catheterization. But this procedure is difficult to proceed in the emergency room. Since central venous oxygen saturation has the advantage of being easily obtained and acts as a good prognostic factor for shock patients, we intended to prove its efficacy. From 1997 May to October, 50 patients admitted to Yonsei University Young Dong Severance Hospital in shock state, with systolic blood pressure below 90mmHg, were evaluated. Central venous catheter was inserted to obtain central venous oxygen saturation, serum lactate, base excess value, and its' initial value compared with the prognosis. The central venous oxygen saturation and base excess were low, while serum lactate value was high in the nonsurvival group. And in ROC(relative operating characteristic) curve, the AUC(area under curve) of central venous oxygen saturation was larger than the others. In comparing the MOF(multi-organ failure) group with the non-MOF group, the MOF group had a lower central venous oxygen saturation and base excess, and a higher serum lactate level, whereas in ROC curve, the AUC of base excess was larger than the others. Therefore, in estimating the prognosis of shock patients, the early central venous oxygen saturation proved to be a good prognostic factor.

To characterize the association between chronic kidney disease (CKD), mortality, severity of coronary artery disease (CAD), treatment modality of CAD, and type of coronary stents among patients undergoing coronary angiography (CAG), we retrospectively reviewed the electronic medical records of the patients who underwent CAG at Seoul National University Bundang Hospital in Korea between May 2003 and January 2006. CKD was staged using an estimated glomerular filtration rate (eGFR) from the creatinine value prior to CAG. There were 3,637 patients included. The presence of CAD was 48% in CKD stage 1, 61% in stage 2, 73% in stage 3, 87% in stage 4, and 81% in stage 5. Survival rate gradually diminished for patients with decreasing renal function. No significant differences in all-cause and cardiac mortality were observed by medical treatment, PCI or CABG, in CKD patients with an eGFR less than 60 mL/min/1.73 m(2). CKD patients with drug-eluting stents showed significantly lower all-cause mortality (5.4% vs. 13.3%) and incidence of myocardial infarction (1.7% vs. 10%) than those with bare metal stents. In conclusion, an eGFR is a strong independent prognostic marker among patients undergoing CAG and the severity of CAD increases progressively with worsening renal function.

Primary renal angiosarcoma is a rare and fatal malignant tumor. About 20 cases have been reported in the literature, but there has been no report of renal angiosarcoma in Korea. A 67-year old man with end-stage renal disease was admitted to the hospital for left flank pain. A computed tomography examination revealed a subcapsular hemorrhage in the left kidney. The patient was discharged after 2 weeks of observation. However, at 6 weeks after the discharge, the patient revisited the outpatient clinic due to aggravating pain, and a left nephrectomy was performed. The histopathological diagnosis was angiosarcoma. Three weeks after the nephrectomy, a re-operation was performed because of uncontrolled intra-abdominal bleeding. The surgical findings revealed massive metastasis. The patient died of an uncontrolled hemorrhage about 1 week after the second surgery. To our knowledge, this is the first report of a renal angiosarcoma in a patient with end-stage renal disease. It should be noted that a renal angiosarcoma may be a cause of a retroperitoneal hematoma.

Patients with stage IV metastatic melanoma have been traditionally managed with mainly palliative therapy such as chemotherapy, radiation therapy or biologic therapy, yet their overall survival is unsatisfactory. Several recent series have indicated a long-term survival benefit after complete resection, (termed "metastasectomy") of distant metastatic foci in patients with metastatic melanoma. Unlike other palliative modalities, surgery like metastasectomy can rapidly render a patient clinically disease-free with rather minimal morbidity, a short-term of hospitalization and a quick recovery time. This may prolong the survival and improve the quality of life of patients with stage IV melanoma if all the clinicoradiologically-evident tumors can be completely resected. We report herein on a case of performing metastasectomy in a patient who had malignant melanoma with soft tissue metastasis of the breast (T3a/bN0M1a), even though there was a regrettable result.

Collagenofibrotic glomerulopathy is a relatively rare glomerular disease characterized by the accumulation of spiraled frayed collagen fibrils in mesangial and subendothelial areas. Clinically, patients with the disease usually present with moderate proteinuria and edema. They tend to have hypertension and their renal function deteriorates slowly. We report the case of a patient with collagenofibrotic glomerulopathy who also had Takayasus arteritis and presented with hypertension, proteinuria and dyspnea on exertion. Electron microscopy of the renal biopsy revealed massive accumulation of peculiar collagen fibers and immunohistology using monoclonal antibodies to collagen type III revealed positive stain in glomerular tufts.

OBJECTIVE: The aim of this study was to identify a standard for the evaluation of future models for prediction of lymph node metastasis in endometrial cancer through estimation of performance of well-known surgicopathological models. METHODS: Using the medical records of 947 patients with endometrial cancer who underwent surgical management with lymphadenectomy, we retrospectively assessed the predictive performances of nodal metastasis of currently available models. RESULTS: We evaluated three models included: 1) a model modified from the Gynecologic Oncology Group (GOG) pilot study; 2) one from the GOG-33 data; and 3) one from Mayo Clinic data. The three models showed similar negative predictive values ranging from 97.1% to 97.4%. Using Bayes' theorem, this can be translated into 2% of negative post-test probability when 10% of prevalence of lymph node metastasis was assumed. In addition, although the negative predictive value was similar among these models, the proportion that was classified as low-risk was significantly different between the studies (56.4%, 44.8%, and 30.5%, respectively; p<0.001). CONCLUSION: The current study suggests that a false negativity of 2% or less should be a goal for determining clinical usefulness of preoperative or intraoperative prediction models for low-risk of nodal metastasis.
