2.Laparoscopy-assisted distal gastrectomy for early gastric cancer and laparoscopic cholecystectomy for gallstone with situs inversus totalis: a case report.
Journal of the Korean Surgical Society 2011;81(Suppl 1):S34-S38
We report our case of laparoscopy-assisted distal gastrectomy with D1 + beta lymph node dissection for a patient with early gastric cancer and laparoscopic cholecystectomy for gallstone with situs inversus totalis. A superficial elevated lesion was found on the lesser curvature of the antrum. The preoperative diagnosis was cStage IA (cT1, cN0, cH0, cP0, cM0). A 1 cm-sized gallstone was found in the fundus through upper abdominal ultrasound. A laparoscopy-assisted distal gastrectomy with standard D2 lymph node dissection for early gastric cancer and laparoscopic cholecystectomy was successfully performed by not shifting the monitor to the left and right and not changing operator's position without additional blood loss and time. The number of retrieved lymph nodes was 36. We have not found any abnormal course of blood vessels except for the right/left inversion. Billroth I reconstruction was performed through end-to-side anastomosis. Based on a histopathological examination, a 1.5 x 1.5 cm, submucosal (sm3), moderately differentiated adenocarcinoma (pT1, pN0, sH0, sP0, sM0, stage IA) was diagnosed. The postoperative course was favorable and the patient was discharged on postoperative day 7.

3.Body fat distribution and hypertension.
Korean Journal of Preventive Medicine 1991;24(1):57-69
This study examined the cross-sectional association of body fat distribution with hypertension as well as the superiority of medical calf skinfold measured as peripheral fat distribution over the conventional triceps skinfold using 450 Korean Navy divers selected by authors' convenience in 1990. Their mean age was 27.9 and range of it was 19-51. The centrally located body fat was approximated by subscapular from these skinfold measures to reflect central versus peripheral fat distribution pattern: 2 ratios and 2 differences. After controlling age and overall obesity (body mass index), prevalence odds ratios of the 2/4, 3/4, 4/4 quartiles of subscapular skinfold comparing with lowest 1/4 quartile were 2.05 (95% confidence interval, CI 1.18-3.59), 2.02 (95% CI 1.06-3.86), 4.00 (95% CI 1.99-8.06) respectively. The difference of subscapular and medical calf skinfolds was associated with hypertension (odds ration 2.45, 95% CI 1.28-4.68 comparing highest with lowest quartiles). Triceps and medical calf skinfolds alone did not show any odds ratio not including unity. The adjusted odds ratios were generally reduced in small magnitude compared with crude odds ratios not adjusted for age and overall obesity. The medical calf skinfold appeared to be more representative of peripheral body fat distribution than triceps skinfold. These findings suggest that central fat distribution rather than peripheral distribution is associated with hypertension independent of age and overall level of obesity and medical calf skinfold may replace conventional triceps skinfold in predicting peripheral distribution of body fat.

BACKGROUND: Several studies have demonstrated that quantitation of hepatitis B virus (HBV) DNA in sera of HBsAg-positive patients is more useful test for the assessment of infectivity and for the evaluation of disease status than previously utilized numerous serological markers and qualitative polymerase chain reaction for the detection of HBV DNA. We tried to measure serum HBV DNA using a branched DNA (bDNA) signal amplification assay, which is recently introduced and known to be a simple and nonradioisotopic method. METHODS: Total forty patients with HBsAg were randomly selected and serum HBV DNA was measured with duplication using bDNA signal amplification assay (QUANTIPLEXTM HBV DNA ASSAY, Chiron, USA). Quantitation was determined from a standard curve and expressed as HBV DNA equivalents/mL (Eq/mL; 1 Eq = 1 molecule of the primary HBV DNA standard). Serum HBeAg, aspartate aminotransferase (AST), alanine aminotransferase (ALT) , and soluble interleukin-2 receptor (sIL-2R) were compared with HBV DNA. RESULTS: Serum HBV DNA was quantitated in 13 patients (32.5%) (range 6.4x106-7.4x109 Eq/mL, mean 1.8x109 Eq/mL, CV 8.1%). All eleven patients (100%) with both HBsAg and HBeAg an4 2 of 29 patients (6.9%) with HBsAg but not with HBeAg showed measurable HBV DNA (p < 0.001). In addition, serum levels of AST, ALT, and sIL-2R were significantly higher in HBV DNA measured patients compared with those of unmeasured patients. CONCLUSIONS: Above results show that more than half the HBsAg-positive patients do not have enough HBV DNA which is measurable with boNA signal amplification assay but all of HBeAg-positive patients and some of HBeAg-negative patients do. In addition, HBV DNA quantitation might be correlated with the disease activity in HBsAg-positive patients because serum levels of AST, ALT, and sIL-2R are higher in patients measured with HBV DNA than unmeasured.

BACKGROUND: T cell mediated immune destruction is an important mechanism of liver injury in patients with chronic hepatitis C. Serum levels of soluble interleukin-2 receptor(sIL-2R) seem to serve as a marker for the T cell activation and progressive liver injury, This study examined serum levels of sIft-2R and hepatitis C virus (HCV) RNA in patients with chronic HCV infection to determine the correlation with the severity of chronic hepatocellular damage. METHODS: Serum levels of sIft-2R in 73 patients with HCV infection (chronic hepatitis 52, liver cirrhosis 9, hepatocellular carcinoma 12) and 40 healthy controls were measured by sandwich enzyme immunoassay (CELLFREE, T Cell Sciences, USA). HCV RNA was quantified by QUANTIPLEX(TM) HCV RNA 2.0 assay (Chiron, USA) with duplication. This assay is a sandwich nucleic acid hybridization procedure using branched DNA amplification for the quantitation of HCV RNA. RESULTS: The sIL-2R levels of 52 patients with chronic hepatitis (591.4+/-238.7U/mL), 9 with liver cirrhosis(949.4+/-721.9 U/mL), and 12 with hepatocellular carcinoma (1,167.4+/- 554.4 U/mL) were significantly higher than those of healthy controls(370.8+/-71.8 U/mL) (p<0.001). A progressive and significant increase occurred in sIL-2R levels with chronic hepatitis C, liver cirrhosis and hepatocellular carcinoma (HCC) in order (p(0.001). The HCV RNA was detected in all patients and the means of HCV viral load were 3.3 MEq/mL in chronic hepatitis, 2.8 MEq/mL in cirrhosis, and 3.7 MEq/mL in HCC. There was no significant correlation between HCV RNA and the severity of liver injury in chronic HCV infection. There were no correlations among sIL-2R, HCV RNA and serum ALT. CONCLUSIONS: These results suggest that chronic hepatocellular injury by HCV progress mainly by T cell mediated immune response, not by direct cytopathic injury. Also, sIL-2R can be useful as a marker in monitoring the patients with HCV infection at high risk of getting HCC.

9.Nutritional Assessment and Perioperative Nutritional Support in Gastric Cancer Patients.
The Korean Journal of Gastroenterology 2013;61(4):186-190
Weight loss and malnutrition are common in cancer patients. Although weight loss is predominantly due to loss of fat mass, the morbidity risk is given by the decrease in muscle mass. The assessment of nutritional status is essential for a diagnosis of nutritional compromise and required for the multidisciplinary approach. Subjective global assessment (SGA) is made by the patients nutritional symptoms and weight loss. The objective assessment, a significant weight loss (>10%) for 6 months is considered an indicator of nutritional deficiency. The mean body index, body fat mass and body protein mass are decreased as cancer stage increases. The biochemical data of albumin, cholesterol, triglyceride, Zn, transferrin, total lymphocyte count are decreased in advanced cancer stage. Daily energy intake, cabohyderate and Vit B1 intake is decreased according to cancer stage. The patients are divided into three groups according to SGA. The three groups showed a significant difference in body weight, 1 month weight loss%, 6 month weight loss%, body mass index, mid arm circumference, albumin, energy intake, as well as carbohyderate intake protein and energy malnutrition. Nutritional assessment is of great importance because undernutrition has been shown to be associated with increase in stomach cancer associated morbidity and mortality. The authors concluded that nutritional assessment should be done in cancer patients preoperatively, and with adequate nutritional support, the morbidity and mortality would be decreased.

Placental site nodules and plaques have been recently described to designated single or multiple, well-circumscribed, rounded lesions at the placental site, composed of viable or degenerating intermediate trophoblastic cells and extensive hyalinization between the cells. We described clinicopathologic findings of 14 cases of placental site nodules and plaques. The age of 14 patients ranged from 25 to 39(average 33) years and all of them had been pregnant in the past. Ten of them presented with vaginal spotting, which was preceded by recent pregnancy in only 3 cases. Three patients presented with secondary infertility and one with secondary infertility and vaginal spotting. Urine pregnancy tests were negative in all 14 cases at the time of presentation. Ultrasonographic examination disclosed abnormalities in only 3 cases and the remaining cases were normal. Hysterosalpingography was performed in 3 patients who presented with 2 degrees infertility and revealed moderate to severe intrauterine adhesions. Microscopically, chronic endometritis of varying degrees evidenced by plasma cells and eosinophiles were present in all cases and these were more prominent in the vicinity of the lesions. It is presumed that the placental site nodules and plaques are not sloughed at the time of menstruation and it may cause chronic endometritis or intrauterine adhesions at any time after previous delivery.
