Continuous arteriovenous hemofiltration(CAVH) is used to treat hemodynamically unstable patients with renal failure, refractory ascites and edema, sepsis, or ARDS patients. Patients received CAVH during a 3-year-period from March 1994 to February 1997. Their clinical findings were analyzed retrospectively, and the results were as follows; They were 6 men and 3 women from 28 to 62 years. 3 patients had ARDS, 2 patients had CHF. The remainder had SLE, liver cirrhosis, septic shock with cholangitis, diabetic ketoacidosis with pulmonary edema. The duration of treatment ranged from 30 to 50 hours, with a mean of 41.6+/-6.9 hours. The total fluid repalcement was 22.4+/-1.7L and the mean fluid loss was 3.9+/-2.6L. Changes in serum BUN, creatinine, sodium, potasium before and after treatment were not significantly diffrent. The complication of CAVH is clotting of hemofilter, hypotension, bleeding, and mild thrombocytopenia. 2 of 3 ARDS patients expired during CAVH, liver cirrhosis patient expired later due to hepatic encephalopathy, and, finally 6 patients discharged with improved conditions. In conclusion, CAVH, a safe and effective therapy in hemodynamically unstable patients with renal failure, refractory ascites and edema, sepsis, or ARDS patients.

Primary vesicoureteral reflux is a common genetically determined condition that is associated with varying degrees of renal scarring and represents one of the main causes of chronic kidney disease in children. Usually vesicoureteral reflux is common in urinary tract infection patient under 5 years of age. However, we report a rare case of high-grade vesicoureteral reflux and chronic kidney disease in a 10-year-old boy who was referred to the pediatric department for incidentally detected asymptomatic bacteriuria. Our case demonstrated that high grade vesicoureteral reflux patient with reduced renal function, bladder and bowel dysfunction at presentation is more likely to progress to chronic kidney disease.

Non-Hodgkin's malignant lymphoma is a relatively frequent lymphoreticular malignancy, and has been reported to constitute up to 5.2% of all malignant tumors in Korean patients. Various morphologic classifications of non-Hodgkin's lymphoma have been proposed, and among them, the Rappaport's classification has been most widely accepted. In 1982, a National Cancer Institute sponsored study on classification led to the creation of the Working Formulation in an attempt to resolve the controversy anddebate regarding the various classifications of non-Hodgkin's lymphoma. Angioimmunoblastic lymphadenopathy with dysproteinemia and polymorphic reticulosis are lymphoreticular proliferative disorders which have reported to transform to malignant lymphoma. The purpose of the present study is to reclassify non-Hodgkin's lymphomas according to the Working Formulation and to investigate the histopathological and immunocytochemical characteristics of angioimmunoblastic lymphadenopathy with dysproteinemia and polymorphic reticulosis. This study reviewed 300 cases of nodal and extranodal non-Hodgkin's lymphoma, 26 cases of polymorphic reticulosis, and 7 cases of angioimmunoblastic lymphadenopathy with dysproteinemia examined in the Departments of Pathology, Yonsei University College of Medicine, Youngdong Severance Hospital and Yonsei University Wonju College of Medicine from January 1977 to December 1986. In non-Hodgkin's lymphoma, each case was classified according to the Working Formulation and the Rappaport classification. All angioimmunoblastic lymphadenopathy with dysproteinemia and polymorphic reticulosis cases were subjected to histopathological analysis and a review of the clinical records. Immunocytochemical studies were done using kappa and lambda chains for B-cell markers and alpha-1-antichymotrypsin for histiocytic marker. The results obtained were as follows; 1) Among 300 cases of non-Hodgkin's lymphoma, the primarily involved tumor sites were the lymph nodes (141 cases), the gastrointestinal tract (67 cases), and the tonsils (32 cases) in descending order of frequency. 2) Using the Working Formulation, intermediategrade lymphomas occurred in 66.4% of the patients, and the most common subtype was "diffuse, large cell" (32.7%). By the Rappaport classification, 3 patients had nodular lymphomas, and "diffuse, histiocytic" was the most common subtype. 3) Infarction was present in 32 cases in which the "diffuse, lagre cell" type was most frequently associated. 4) In immunoperoxidase stains of 7 cases of angioimmunoblastic lymphadenopathy with dysproteinemia, proliferating immunoblasts revealed a polyclonal positivity for kappa and lambda chains. Atypical reticulocytes present in 26 cases of polymorphic reticulosis revealed a negativity for kappa, lambda and alpha-1-antichymotrypsin.

PURPOSE: Platycodon grandiflorum (PG) is known to have effective antimicrobial and anticancer activity. The main bioactive components of PG are saponins, and these could contribute to anti-inflammatory activity. However, little is known about the anti-inflammatory effect of PG. In this study, we aim to assess the anti-inflammatory response to Red PG Extract (RPGE) in splenocytes under ex vivo conditions. METHODS: The cell viability of isolated splenocytes taken from mice was analyzed by performing a Cell Counting Kit-8 assay. The productions of nitric oxide (NO) and cytokines (specifically interleukin-6 (IL-6) and interleukin-10 (IL-10)) were measured utilizing Griess reagent and ELISA, respectively. RESULTS: We found that co-treatment with RPGE and Lipopolysaccharide (LPS) decreased isolated splenocyte proliferation as compared with that of the LPS-stimulated control. We also observed that RPGE markedly suppressed NO synthesis and IL-6 production that was induced by LPS. There were no significant differences of IL-10 production between co-treatment with RPGE plus LPS and treatment with LPS alone. CONCLUSION: When taken together, our data has shown that RPGE mitigates LPS-induced inflammation in splenocytes isolated from mice. Further research is surely needed to confirm the anti-inflammation effects of RPGE in an in vivo model.

Purpose: Pediatric diabetes is a common health burden worldwide. This study aimed to investigate the prevalence of fasting hyperglycemia in Korean youth aged 10–18 years and to evaluate its association with metabolic indicators. Methods: To assess the risk of diabetes in domestic children and adolescents, the prevalence of fasting hyperglycemia was calculated, a trend was evaluated using multi-year Korea National Health and Nutrition Examination Survey (KNHANES) data, and multivariate analysis was performed to evaluate the relationships between hyperglycemia and metabolic factors. Results: The prevalence of fasting hyperglycemia, defined as impaired fasting glucose (fasting glucose level > 100 mg/dL and < 125 mg/dL), or diabetes mellitus (fasting glucose ≥ 126 mg/dL) was estimated in Korean teenagers. The prevalence increased from the fourth (2007–2009) to the fifth (2010–2012), sixth (2013–2015), and seventh (2016–2018) KNHANES surveys, from 5.39 to 4.79, 10.03, and 11.66 per 100 persons, respectively. In multivariate analysis, systolic blood pressure and serum triglycerides were higher in the fasting hyperglycemia group; systolic blood pressures were 109.83 mmHg and 112.64 mmHg and serum triglycerides were 81.59 mg/dL and 89.60 mg/dL in the normal blood glucose and fasting hyperglycemia groups, respectively. Conclusion The prevalence of fasting hyperglycemia among children and adolescents has increased over the past decade, and this increase is potentially associated with metabolic abnormalities such as hypertension and hypertriglyceridemia. Effort is urgently required to reduce this chronic medical burden in adolescence.

Endoscopic polypectomy was firstly introduced by Tsuneoka in 1969, and till now this method has been widely used for the treatment of benign and malignant polyps with the advent of technical improvement. This method is a very important modality as secondary prevention of malignancy because polyps in gastraintestinal tract are now being considered as precancerous lesion. Polypectomy with snare and electrocautery is mainly used for pedunclated polyps (eg. Yamada Class III, IV), but sessile polyps pose technical difficulty and occasionally cause serious gastrointestinal hemorrhage when resection margin adjacent polyp base. We performed polypectomy with "O"-ring used in endocopic variceal ligation (EVL) to make sessile polyp as semipedunclated form, and also to control bleeding, and then successfully remove it with conventional snare polypectomy. We report these 5 cases with the review of the literature.
