PURPOSE: To describe the current status of airway management for trauma patients in the emergency department (ED) and to evaluate the success rate and associated factors for selecting the Glidescope video laryngoscope. METHODS: This was a retrospective observational study of prospectively collected data from the Koran Emergency Airway Management Registry in two university hospitals between April 2006 and March 2010. The study population included all trauma patients presenting at the ED who required emergency airway management. Demographic and airway related parameters were collected. The success rate was compared between the Glidescope and the direct laryngoscope. Factors associated with selecting the Glidescope were analyzed using multiple logistic regression. RESULTS: Among the 1,974 patients who received airway management in the ED during the study period, 341 were identified as trauma patients. The Glidescope was used in 130 (38%) of the patients. Difficult airway was identified in 46.9% of the Glidescope group compared with 22.6% in the direct laryngoscope group (p<0.001). Success rate on the first attempt was not different between the direct laryngoscope and the Glidescope. The Glidescope was selected in favor of cervical immobilization, difficult airway, and senior grade resident. CONCLUSION: Among intubated patients in the ED, trauma patients accounted for 17.6%. The Glidescope video laryngoscope was selected in 38% of cases. It was usually used in cases of difficult airway such as cervical immobilization by senior grade residents.

Annular pancreas is a rare congenital anomaly in which a thin band of pancreatic tissue partially or completely surrounds the duodenum.It is challenging to diagnose due to its variable clinical presentation. Approximately two-thirds of patients have no symptoms in their lifetime, and most symptomatic cases are seen in neonates and infants. Symptomatic adult patients present with upper gastrointestinal symptoms, such as epigastric pain, vomiting, and postprandial fullness associated with gastric outlet obstruction. Complications associated with annular pancreas include peptic ulcer disease, pancreatitis, pancreatic head carcinoma, and biliary obstruction. Annular pancreas is also a rare cause of upper gastrointestinal bleeding in adults, but it should be considered as one of the differential diagnoses in patients presenting with a peptic ulcer and duodenal stricture. Here, we report the case of a 60-year-old man who presented with melena and was subsequently diagnosed with an annular pancreas.

PURPOSE: Tumor invasion and metastasis are known to be extremely important factors in the prognosis of cancer patients. Although recent studies have demonstrated that cyclooxygenase-2 (COX-2) is overexpressed in various cancers including gastric cancer, the mechanisms underlying the contribution of COX-2 to tumorigenesis and tumor promotion remain unclear. METHODS: In order to determine the role of COX-2 in tumor growth and metastasis, we investigated COX-2 expression, apoptosis and the expression of E-cadherin, CD44v6, MMP-2 and TIMP-2 in gastric cancer xenografts treated with meloxicam (a selective COX-2 inhibitor). RESULTS: Cells from the MKN45 gastric cancer cell line that overexpress COX-2 were inoculated subcutaneously into athymic mice. Oral administration with meloxicam reduced the tumor volume (P<0.01), induced apoptosis of cancer cells (P<0.01), suppressed the proliferation rates (P<0.01), increased the expression of E-cadhrin (P<0.05) and reduced the expression of MMP-2 and TIMP-2. CONCLUSION: The above data showed that COX-2 inhibitors can inhibit tumor growth and suppress metastatic potential by expression of adhesion molecules and suppression of metalloproteinases, suggesting that this inhibitor can be used as an additive anti-cancer drug in cases of stomach cancer with radical resection, although further evaluation is required.

This study was carried out to identify the phylogenetic relationships among several caterpillar fungi by comparing the sequences of internal transcribed spacer regions (ITS1 and ITS2) and 5.8S ribosomal DNA (rDNA) repeat unit. The sequences of ITS1, ITS2, and the 5.8S rDNA from 10 strains of Cordyceps species, 12 strains of Paecilomyces, 3 strains of Beauveria, 2 strains of Metarhizium and 1 strains of Hirsutella were amplified, determined and compared with the previously known Cordyceps species. The sequences of 5.8S rDNA were more conserved in length and variation than those of ITS regions. Although the variable ITS sequences were often ambiguously aligned, the conserved sites could be found. In the phylogenetic tree, the species generally divided into three clusters, supported by their morphology and/or host ranges. The 5.8S rDNA and ITS1 sequences among 10 species of Cordyceps militaris were identical and only one base pair in ITS2 sequence was different. Cordyceps sinensis and Cordyceps ophioglossoides were also clearly different, although they belonged to the same cluster. The GenBank database search of species revealed sister taxa of an entomogenous fungus. Metarhizium was used as an outgroup in all taxa.
