BACKGROUND: Postoperative sore throat (POST) is a complication that undermines patient satisfaction and increases discomfort in the postoperative period. The present study examined the effects of dexamethasone gargle and endotracheal tube cuff soaking on the incidence and severity of POST. METHODS: Ninety patients undergoing laparoscopic cholecystectomy were randomly allocated into three groups: 0.9% normal saline gargling and tube soaking (group C), 0.05% dexamethasone solution gargling and 0.9% normal saline tube soaking (group G), 0.9% normal saline gargling and 0.05% dexamethasone tube soaking (group S). The incidence and severity of POST were then assessed and recorded at 24 hours after surgery. RESULTS: The total incidence of POST was significantly different among the groups (P < 0.05), and group S exhibited a significantly lower incidence of POST than group C (P < 0.0167). In addition, the POST intensity of group G and group S was less severe than those of group C (Both P < 0.0167). CONCLUSIONS: Among patients undergoing laparoscopic cholecystectomy, those who gargled with 0.05% dexamethasone solution exhibited lower severity of POST than the control group, and those whose endotracheal tube cuff was soaked in the dexamethasone solution before intubation exhibited significantly lower incidence and severity of POST than the control group.

We conducted this study to investigate the synergistic effect of human urine-derived stem cells (USCs) and surface modified composite scaffold for bladder reconstruction in a rat model. The composite scaffold (Polycaprolactone/Pluronic F127/3 wt% bladder submucosa matrix) was fabricated using an immersion precipitation method, and heparin was immobilized on the surface via covalent conjugation. Basic fibroblast growth factor (bFGF) was loaded onto the heparin-immobilized scaffold by a simple dipping method. In maximal bladder capacity and compliance analysis at 8 weeks post operation, the USCs-scaffold(heparin-bFGF) group showed significant functional improvement (2.34 ± 0.25 mL and 55.09 ± 11.81 microL/cm H2O) compared to the other groups (2.60 ± 0.23 mL and 56.14 ± 9.00 microL/cm H2O for the control group, 1.46 ± 0.18 mL and 34.27 ± 4.42 microL/cm H2O for the partial cystectomy group, 1.76 ± 0.22 mL and 35.62 ± 6.69 microL/cm H2O for the scaffold group, and 1.92 ± 0.29 mL and 40.74 ± 7.88 microL/cm H2O for the scaffold(heparin-bFGF) group, respectively). In histological and immunohistochemical analysis, the USC-scaffold(heparin-bFGF) group showed pronounced, well-differentiated, and organized smooth muscle bundle formation, a multi-layered and pan-cytokeratin-positive urothelium, and high condensation of submucosal area. The USCs seeded scaffold(heparin-bFGF) exhibits significantly increased bladder capacity, compliance, regeneration of smooth muscle tissue, multi-layered urothelium, and condensed submucosa layers at the in vivo study.

Gallstone ileus is a rare complication of the biliary stone, occurring in 0.3-0.5% of patients with cholelithiasis. The mortality rate is high at 12-27% and early diagnosis and prompt management can improve its prognosis. An 83-year-old woman was admitted to the hospital with abdominal pain. The patient previously had a hysterectomy and had received radiation therapy for uterine cancer. Plain abdominal x-ray showed typical findings of small bowel ileus with step ladder patterns. Computed tomography (CT) scan revealed biliary-enteric fistula with a 3-cm-sized gallstone in the jejunal loop. Surgical treatment was planned but due to the patient's wish, conservative treatment was provided for 10 days. In the follow-up CT scan, the stone had moved to the distal ileum but intestinal perforation was suspected. Ileocecectomy and adhesiolysis were performed and the patient recovered fully. Here we report a case of gallstone ileus that was treated by surgical removal after 10 days of conservative treatment.

Red ginseng and its extracts have been used as traditional medicines and functional foods in countries worldwide. The aim of this study was to examine the bioavailability of pectin lyase-modified red ginseng extracts (GS-E3D), and the effects of GS-E3D on adipogenesis of 3T3-L1 adipocytes, as well as on metabolic disorders such as hyperglycemia, dyslipidemia, and fatty liver in high-fat diet fed obese C57BL/6 mice. Mice were divided into 5 groups: normal diet group, high fat diet-vehicle group, high fat diet + 0.1 g/kg GS-E3D (0.1-GS-E3D), high fat diet + 0.3 g/kg (0.3-GS-E3D), high fat diet + 1.0 g/kg (1.0-GS-E3D). Treatment of GS-E3D reduced differentiation of 3T3-L1 adipocytes with low cytotoxicity. In the animal model, compared to the high fat diet control, serum glucose, total cholesterol, LDL-cholesterol, HDL-cholesterol, TG, and leptin level were reduced in treatment animals in a dose-dependent manner. In addition, we found that GS-E3D could decrease total hepatic lipid droplets. These results suggest that GS-E3D, as a dietary supplement, has beneficial effects on obesity and may have useful effects in health-care products.

BACKGROUND: The administration of a single dose of propofol is reported to be effective in decreasing the incidence and severity of emergence agitation (EA) in children following sevoflurane anesthesia. The aim of this study was to investigate the clinical usefulness of a single dose of propofol 1 mg/kg at the end of adenotonsillectomy for reducing the incidence of EA after sevoflurane anesthesia. METHODS: Ninety children, aged 3-8 years, undergoing adenotonsillectomy were randomized into two groups: the propofol group (n = 45) and the saline group (n = 45), of which 88 children completed the study. Anesthesia was maintained with sevoflurane 2-2.5 vol% and nitrous oxide/oxygen (50%/50%). At the completion of adenotonsillectomy, the propofol group patients were given 1 mg/kg of propofol and the saline group patients were given saline 0.1 ml/kg in the same volume. The incidence of EA was assessed with Aono's four point scale and the severity of EA was assessed with pediatric anesthesia emergence delirium (PAED) scale at 5 min (T5), 15 min (T15) and 30 min (T30) after emergence. RESULTS: Of the 88 patients, the incidence of EA at T5, T15 and T30 was 61.4%, 27.3%, and 4.5% in the propofol group while in the saline group was 68.2%, 29.5%, and 9.1%, respectively. The incidence and severity of EA were not found to be significantly different between the two groups, but the scales in each group decreased significantly over time. CONCLUSIONS: The administration of propofol 1 mg/kg at the end of surgery did not have any significant effect in reducing the incidence and severity of EA in children undergoing adenotonsillectomy under sevoflurane anesthesia.

BACKGROUND: Postoperative nausea and vomiting (PONV) is extremely distressing and uncomfortable, and is noted frequently in patients who have undergone gynecologic laparoscopic surgery. In this study, we compared the efficacy of a combination of ramosetron plus dexamethasone and ramosetron alone in reducing of PONV after gynecologic laparoscopic surgery. METHODS: Sixty patients who received gynecologic laparoscopic surgery were randomly divided into two groups: the R group (ramosetron 0.3 mg) and RD group (ramosetron 0.3 mg plus dexamethasone 5 mg). Dexamethasone, 5 mg, or saline, 1 ml, was administered randomly before the induction of anesthesia in each group. The two groups received intravenous ramosetron, 0.3 mg, at the end of surgery. General anesthesia was induced using thiopental and rocuronium, and maintained with sevoflurane in nitrous oxide. The incidence and severity of nausea, frequency of vomiting and rescue medication, VAS score, and adverse events were evaluated for 48 hours after the operation. RESULTS: In the first 12 hours after operation, the incidence of PONV in the RD group (33%) was significantly lower than the R group (67%; P < 0.05). However, there were no significant differences between two groups in PONV incidence 12-48 h postoperatively. Adverse events and VAS scores were similar in the two groups. CONCLUSIONS: The combination of ramosetron plus dexamethasone is superior to ramosetron alone for prevention of PONV during the first 12 hours after gynecologic laparoscopic surgery.

Benzidine Industry in Korea has started after Japan has banned its production in early 1970's. and it has been in operation in Korea for over 20 years. However, it is not known yet whether any bladder cancer has developed from benzidine exposure. This study was done to screen benzidine-exposed workers for bladder cancer, and to examine the feasibility of employing screening test at the workplace. All the workplaces that manufacture or use benzidine for more than 20 years in Korea have been covered in this study, and they include 2 benzidine manufacturing factories, 5 benzidine using factories, as well as 2 benzidine free factories as an outside control. In total, 516 workers were screened with urine stick test and urine cytology test for the evidence of hematuria and abnormal urothelial cells. Each worker was also asked about risk factors and symptoms of bladder cancer including past medical history, smoking, medication and occupational history. Benzidine in the air was measured by personal and area sampling. Out of 516 screened workers, 84(16.3%)workers showed positive hematuria in urine stick test, and 7(1.4%)workers showed degenerative cells in urine cytology tests. Those workers with abnormal urine test results who have been exposed to benzidine for more than 10 years were further screened, and, in total. 23 workers were examined with intra-venous pyelography and cystoscopy. None of those screened had any evidence of bladder cancer. When workers with only past hematuria history were included in the positive hematuria group, 96(18.5%) had positive hematuria. On the multiple logistic regression analysis, positive hematuria was significantly associated with benzidine exposure history of other occupations with elevated bladder cancer risk, pyuria and glycosuria. The association got stronger as direct benzidine exposure was accounted through individual task analysis, and as exposure duration was accounted with tenure analysis. For those with benzidine exposure with more than 10 years of tenure, the odds of having positive hematuria was elevated 2.14(95%C.I is 1.08 to 4.25) times more than for those without exposure. Even though bladder cancer was not detected for several limitations including short observation period, majority of studied workers with short latency, healthy worker effect, and low sensitivity of single screening test in a cross-sectional study, the study results suggest that hematuria screening is a feasible and very useful test for bladder cancer screening among benzidine exposed workers.

Growth factors are polypeptide molecules that regulate cell growth and function by binding with high affinity to specific receptor molecules in the plasma membrane and stimulating receptor mediated action of intracellular signal transduction pathway.Epidermal growth factor(EGF) and their receptors(EGFR) regulate normal cellular growth, proliferation, and differentiation of various cells in vivo and in tissue cultures. And also may contribute directly to oncogenesis.Overexpression of EGFR and autocrine stimulation of growth involving this receptor system has been identified in several types of human neoplasia. There is evidence that the EGF and receptor system is involved in the regulation of follicular cell growth in the thyroid gland especially with immunohistochemical technic. But there was a challenge about the validity of previously performed immunohistochemical studies.In the study we investigated the relationship between EGFR mRNA expression and tumorigenesis by rapid in situ hybridization method. Formalin-fixed, paraffin embedded tissue sections of 10 normal, 17 nodular hyperplasia, 6 follicular adenoma, and 15 papillary cancer were examined. The results were as follows:1) EGFR mRNA positivity were 20%(2/10) in normal thyroid, 70%(12/17) in nodular hyperplasia, and 100% in follicular adenoma and papillary cancer.2) There was a significantly increased EGFR mRNA expression in papillary cancer compare to normal and nodular hyperplasia(p<0.05). But no difference was found with papillary cancer and follicular adenoma.3) There was a significantly increased EGFR mRNA expression in follicular adenoma compare to normal (p<0.05). But no difference was found with follicular adenoma and nodular hyperplasia. These results suggest that an overexpression of EGFR mRNA may play an important role in the tumorigenesis of thyroid tissue.
