Cellular oncogenes are expressed as an intrinsic part of the transformed or neoplastic phenotype. More than 60 of the known cellular oncogenes play a specific role in normal cellular development and differentiation. To examine the correlation between ras oncogene expression and the development of cervical cancer, this study investigated the reactivity of cervical intraepithelial neoplasia(CIN) and carcinoma of the uterine cervix by using anti-ras P21 mouse monoclonal antibody. The expression of ras oncogene significantly increased with the grade of malignancy from 11% in severe dysplasia, 30% in carcinoma in situ, 43% in microinvasive carcinoma, to 53% in invasive cancer. The expression of ras oncogene was not correlated with histologic type, tumor size, and nodal status of cervical cancer. It was concluded that expression of ras oncogene is related to early phase of carcinogenesis and tumor invasion of carcinoma of the uterine cervix.

Fetal bilateral renal agenesis is a lethal congenital anomaly. An early and reliable prenatal diagnosis is extremely important as it may offer options for pregnancy termination as early as possible. The criteria for the ultrasonographic diagnosis of bilateral renal agenesis are severe oligohydramnios, nonvisualization of the bladder, and the empty renal fossa. However, severe oligohydramnios makes it difficult to diagnose the disease because of poor sonographic resolution. We present two cases of bilateral renal agenesis, one is diagnosed by ultrasonography after amnioinfusion at 24 weeks gestation, the other is diagnosed postnatally after term delivery.

BACKGROUND: Postoperative admission to the surgical intensive care unit (S-ICU) is commonly planned to prevent and treat complications, unnecessary admission to the S-ICU increases medical costs and length of hospital stay. This study aimed evaluated outcome and the predictive factors for mortality in patients admitted to the S-ICU after abdominal surgery. METHODS: The 168 patients admitted to the S-ICU immediately after abdominal surgery were reviewed retrospectively from January to December 2011. RESULTS: The mortality rate of patients admitted to the S-ICU after abdominal surgery was 8.9% (15 of 168). Two preoperative factors (body mass index [BMI] < 18.5 kg/m2 [p < 0.001] and serum albumin < 3.0 g/dL [p = 0.018]), two operative factors (the need for transfusion [p = 0.008] or vasopressors [p = 0.013] during surgery), and three postoperative variables (mechanical ventilation immediately following surgery [p < 0.001], sequential organ failure assessment [p = 0.001] and SAPS II [p = 0.001] score) were associated with mortality in univariate analysis. After adjusting for age, gender, and SAPS II by a Cox regression, which revealed that BMI < 18.5 kg/m2 (p < 0.001, hazard ratio [HR] 9.690, 95% confidence interval [CI] 2.990-25.258) and the use of mechanical ventilation on admission to S-ICU (p < 0.001, HR 34.671, 95% CI 6.440-186.649) were independent prognostic factors. CONCLUSIONS: In patients in S-ICU after abdominal surgery, low BMI and postsurgical mechanical ventilation should be considered important predictors of mortality.

BACKGROUND: Liver transplantation (LT) is a complicated procedure with a high incidence of postoperative acute kidney injury (AKI). Previous studies indicate that even transient or mild post-LT AKI can result in critical conditions, including prolonged stays in hospitals and intensive care units and increased morbidity and mortality. The aim of this study was to investigate the association between body mass index (BMI) and occurrence of AKI in LT recipients. METHODS: Medical data from 203 patients who received LT surgery from January 2010 to August 2016 in a single university hospital setting were retrospectively collected and analyzed. Patients were classified as either underweight (BMI <20 kg/m²) or normal weight (20 ≤ BMI < 30 kg/m²). Demographic data, anesthetic methods, complications, and perioperative laboratory test values of each patient were assessed. Propensity analyses and logistic regression were performed to evaluate the association between BMI and post-LT AKI. RESULTS: There was no significant difference in occurrence of post-LT AKI between underweight and normal weight patients. The underweight patient group had significantly longer hospital stay compared with the normal weight patient group (P = 0.023). CONCLUSIONS: BMI classification was neither a positive nor negative predictor of postoperative AKI occurrence. However, patients with lower BMI had significantly longer hospital stay compared with their counterparts. Although our study was limited by its retrospective design, our observations suggest that lower BMI might play a role in post-LT AKI.

OBJECTIVE: This study was designed to identify the prevalence and clinical features of hyperuricemia in Gwangju and Jeonnam territories. METHODS: We enrolled 2309 participants who underwent health examinations at Chosun University Hospital from January 2008 to June 2010. All participants were free from gout, diabetes, hypertension, rheumatoid arthritis, dyslipidemia, cerebral infarction, cardiovascular disease, cancer, asthma, and autoimmune disease. Hyperuricemia was defined as > or =7 mg/dL in males and > or =6 mg/dL in females. Metabolic syndrome was defined using the International Diabetes Federation (IDF) criteria, which were revised in 2005. Clinical profiles were investigated, including age, waist circumference (WC), body- mass index (BMI), fasting glucose, HbA1c, triglycerides, total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), blood pressure (BP), high-sensitivity-C-reactive protein (hs-CRP), homocysteine, fibrinogen, total bilirubin, gamma-glutamyl transferase (r-GT), aspartate aminotransferase/alanine aminotransferase (AST/ALT), alcohol consumption, smoking and exercise. RESULTS: The overall prevalence of hyperuricemia was 9.8% among our study. The condition was more common in males than in females (15.0% vs 4.1%). Uric acid concentration was correlated with WC, BMI, BP, triglycerides, total cholesterol, hs-CRP, and r-GT (p<0.05). Additionally, among males, uric acid concentration was correlated with WC. The prevalence of metabolic syndrome increased when uric acid concentration increased. Males with hyperuricemia had 2.3-fold higher risk of metabolic syndrome (odds ratio (OR)=2.33). Female with hyperuricemia had 2.8-fold higher risk of metabolic syndrome (OR=2.78) as compared to those without hyperuricemia. CONCLUSION: The overall incidence of hyperuricemia was 9.8%. The prevalence of metabolic syndrome increased along with increases in uric acid concentration. Hyperuricemia may be positive predictive factor for metabolic syndrome and also may be risk factor in cardiovascular morbidity.

Large numbers of reports have shown that thermal injury (TI) causes a wide spectrum of defects in immune response that lead to a high susceptibility to various opportunistic infections. However, it is still a matter of debate whether TI induces Th2 polarization or global impairment in Th1/Th2 response. In this study, TI in a mouse model was induced by exposing shaved dorsal skin to boiling water and cytokine production was analyzed. At day 2 of injury, whole spleen cells and T cells were collected and then stimulated with an anti-CD3 antibody. The levels of cytokine secretion were determined by cytokine ELISA. Production of IFNgamma and IL 4 by whole spleen cells from injured mice were concurrently decreased when compared to those from sham-injured controls. Proportional changes in T, B, and T-subset cells were not accompanied. Using purified T cells devoid of accessory cells (AC), it was shown that those defects resulted primarily from lowered T cell potentials. By using mixed cultures of sham T and TI-AC and vice versa, it was revealed that AC also acted as inhibitor cells in IFNgamma and IL 4 production in less extent. Blockade of glucocorticoid signals rendered the T cells partially resistant to TI-induced inhibition in IFNgamma and but not IL 4 production. These results clearly demonstrate that TI induces overall suppression in Th1 and Th2 response through T cell dysfunction together with the inhibition of AC activity, and that reduction in only IFNgamma but not IL 4, production may be caused, in part, by corticosteroid hormone that is secreted prominently during trauma.
