Duplications of the stomach account for only 3.8% of gastrointestinal duplication, mainly discovered during first year of life. Etiopathogenesis is unknown. The most widely accepted theory is recannalization with fusion of longitudinal epithelial fold. The most frequent presented symptoms and signs include gastric outlet obstruction with vomiting, and palpable mass in the epigatric area. An upper gatrointestinal series usually reveals evidence of extrinsic mass effect of intramural lesion. An abdominal ultrasonographic finding is cystic mass lesion with double layer. Histologically, the wall of intramural cyst is composed of orderly layers of alimentary mucosa, submucosa, and muscle fibers. Recommended management is complete excision & simple closure of duplication without violation of the gastric lumen. In this case, 3-day old male newborn suffered from symptoms of gastric outlet obstruction, multiple gastric duplication cysts were found in pyloric canal and greater curvature. The cystic wall was composed with typical 3 layers of gastric mucosa, submucosa, and muscle fibers. The cystic wall was composed with typical 3 layers of gastric mucosa, submucosa, and muscle fibers. Surgical excision was successfully done.

PURPOSE: This study aims to establish a new strategy that provides for the rapid establishment of human clonal adipose derived stem cell (hADSC) lines with aspirated adipose tissue and to characterize newly generated hMSC lines for their cell phenotype, differentiation potential, lineage-specific gene expression. METHODS: Human adipose tissue-derived stem cells (hADSCs) were isolated from subcutaneous adipose tissue based on standard protocols. After incubation for 2 h, only the cell culture supernatant was transferred to a new dish. This process was repeated several times with 30 h incubations. RESULTS: We confirmed the difference in growth rate, however, differences were not seen in the differentiation capabilities and stemness of the each cell lines. CONCLUSION: It is necessary to establish cell lines via single cell level for application to disease specific tissue engineering.

The frictional force has been considered as an harmful factor in an active unit where tooth movement occurs, but as an advantageous factor in anchor unit that resist tooth movement. That is, efficient tooth movement is planned by using ligation methods that have low levels of bracket-wire frictional force and the anchorage control can be achieved by using ligation methods that have high levels of bracket-wire frictional force that result in binding of the bracket accompanied by little or no tooth movement. The purpose of this study was to evaluate the frictional force generated between bracket and wire in accordance with the methods of ligation, the material of ligation and the passage of time under artificial saliva. Tested were 0.017X0.022 inch stainless steel wires in standard edgewise twin brackets for upper central incisors in a 0.018-inch slot The wires were ligated into the brackets with elastomeric modules and stainless steel ligatures. Whole tie, half tie, twisting tie and double overlay tie were done with elastomeric modules. With 0.009-inch stainless steel ligature whole tie and half tie were done by needle holder and whole tie by ligature tying plier. With 0.012-inch stainless steel ligature whole ties were done by needle holder. Whole tie groups of elastomeric module were kept in artificial saliva bath at 37degress C for 28 days. The frictional force was recorded by means of an Instron universial testing instrument (4202 INSTRON, Instron Co., U.S.A.) at initial, 7, 14, 21, and 28 days. The results for ligated samples in a simulated oral environment revealed the following: In elastomeric module whole tie, 28 days group was significantly greater mean static frictional force than any other group but there were no significant differences among any other group (p>0.05). Elastomeric module twisting ties were significantly greater mean static frictional forces than any other ligation method but there were no significant differences between twisting tie and double overlay tie (p>0.05). Twisting tie, double overlay tie, whole tie, half tie showed differences in decreasing order. Stainless steel half tie produced lower mean static frictional forcee than whole tie, ligation by ligature tying plier produced greater mean static frictional force than by needle holder and ligation with 0.012-inch stainless steel ligature produced greater mean static frictional force than with 0.009-inch stainless steel ligature (p<0.05). There were no significant differences between the mean static frictional forces of elastomeric whole tie and stainless steel whole tie (p>0.05).

Nerve sheath myxoma or neurothekeoma, a rare cutaneous neoplasm probably originating from the nerve sheath, is classified into three groups as classical, cellular, and mixed types based on cellularity, mucin content and growth patterns. Only two cases of nerve sheath myxoma have been reported in the Korean literatures. We report a case of nerve sheath myxoma occurring on the scalp of a 29 year-old woman. It was identified as the mixed type by histopathological, immunohistochemical and electronmicroscopic findings.

Recently, self-etching adhesive system has been introduced to simplify the clinical bonding procedures. It is less acidic compared to the phosphoric acid, thus there is doubt whether this system has enough bond strength to enamel. The purpose of this study was to investigate the influence of additional etching on the adhesion of resin composite to enamel. Ninety extracted bovine permanent anterior teeth were used. The labial surfaces of the crown were ground with 600-grit abrasive paper under wet condition. The teeth were randomly divided into six groups of 15 teeth each. Clearfil SE Bond(R), Adper(TM) Prompt L-Pop and Tyrian SPE(TM) were used as self-etching primers. Each self-etching primers were applied in both enamel specimens with and without additional etching. For additional etching groups, enamel surface was pretreated with 32% phosphoric acid (UNI-ETCH, Bisco, Inc., Schaumburg, IL, USA). Hybrid resin composite Clearfil AP-X, (Kuraray Co., Ltd., Osaka, Japan) was packed into the mold and light-cured for 40 seconds. Twenty-four hours after storage, the specimens were tested in shear bond strength. The data for each group were subjected to independent t - test at p < 0.01 to make comparisons among the groups. In Clearfil SE Bond(R), shear bond strength of additional etching group was higher than no additional etching group (p < 0.01). In Adper(TM) Prompt L-Pop and Tyrian SPE, there were no significant difference between additional etching and non-etching groups (p > 0.01). In conclusion, self-etching adhesive system with weak acid seems to have higher bond strength to enamel with additional etching, while self-etching adhesive system with strong acid seems not.

PURPOSE: This study was conducted to evaluate the survival differences between curative stage IV and non-curative stage IV gastric cancers after gastrectomy. METHODS: Stage IV gastric cancer patients who received gastrectomy were selected from our surgical data-base from 1995 to 2004. These patients were separated into two groups according to the curability by surgery. We analyzed the survival differences between curative stage IV patients and non-curative stage IV patients. Survival analysis was performed by Kaplan-Meier survival analysis. RESULTS: During a 10-year period, gastrectomy was performed in 2,214 patients. 224 patients were diagnosed as stage IV. 144 patients were male and 80 patients were female. 97 patients received total gastrectomy. 127 patients received subtotal gastrectomy. 173 patients were diagnosed with curative stage IV and 51 patients were non-curative stage IV. Overall 3-year and 5-year survival rates of stage IV gastric cancer patients in this study were 31.5% and 18.4%. 3-YSR of curative and non-curative stage IV were 36.0% and 16.7% respectively (P-value=0.0204). 5-YSR of curative and non-curative stage IV was 21.9% and 4.2% (P-value=0.0169). CONCLUSION: Significant survival differences were found between curative and non-curative stage IV. Although direct tumor extension or distant metastasis exists, gastrectomy with combined resection was important to improve prognosis if it is possible to resect. When it comes to the matter of survival rate, the subclassification of stage IV gastric cancer should be considered for further management.

BACKGROUND: Postoperative nausea and vomiting (PONV) occurs in up to 63-84% of patients after thyroid surgery. This study aims to assess the effects of using a capsicum plaster to reduce PONV after thyroid surgery at either the Chinese acupuncture point (acupoint) Pericardium 6 (P6) or Korean hand acupuncture point K-D2. METHODS: One-hundred eighty-four patients who underwent thyroid surgery were randomized in four groups (n = 46 each): control group = inactive tape at P6 acupoints and on both shoulders as a nonacupoint; P6 group = capsicum plaster at P6 points and inactive tape on both shoulders; K-D2 group = capsicum plaster at K-D2 acupoints and inactive tape on both shoulders; Sham group = capsicum plaster on both shoulders and inactive tape at P6 acupoints. The capsicum plaster was applied before the induction of anesthesia and removed at 8 hr after surgery. RESULTS: The incidence and severity of nausea and vomiting and the need for rescue antiemetics were decreased in the patients in the P6 and K-D2 groups compared to the patients in the control and sham groups (P < 0.001). The patients in the P6 and K-D2 groups also reported that they were more satisfied (P < 0.05). CONCLUSIONS: We conclude that the capsicum plaster at the P6 and K-D2 acupoint was a promising antiemetic method for the patients undergoing thyroid surgery.
