Korean Society of Thyroid-Head and Neck Surgery appointed a Task Force to provide guidance on the implementation of a surgical treatment of oral cancer. MEDLINE databases were searched for articles on subjects related to “surgical management of oral cancer” published in English. Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies. The quality of evidence was rated with use RoBANS (Risk of Bias Assessment Tool for Nonrandomized Studies) and AMSTAR (A Measurement Tool to Assess the Methodological Quality of Systematic Reviews). Evidence-based recommendations for practice were ranked according to the American College of Physicians grading system. Additional directives are provided as expert opinions and Delphi questionnaire when insufficient evidence existed. The Committee developed 68 evidence-based recommendations in 34 categories intended to assist clinicians and patients and counselors, and health policy-makers. Proper surgical treatment selection for oral cancer, which is directed by patient- and subsite-specific factors, remains the greatest predictor of successful treatment outcomes. These guidelines are intended for use in conjunction with the individual patient's treatment goals.

There are many different approaches to ultrasound-guided supraclavicular brachial plexus block (US-SCBPB), and each has a different success rate and complications. The most commonly performed US-SCBPB is the corner pocket approach in which the needle is advanced very close to the subclavian artery and pleura. Therefore, it may be associated with a risk of subclavian artery puncture or pneumothorax. We advanced the needle into the central part of the neural cluster after penetrating the sheath of the brachial plexus in US-SCBPB. We refer to this new method as the "central cluster approach." In this approach, the needle does not have to advance close to the subclavian artery or pleura. The aim of this study was to evaluate the clinical outcomes of the central cluster approach in US-SCBPB.

This study examined salivary flow and salivary pH and the prevalence and levels of cariogenic bacteria in the saliva of oncological patients and healthy controls. Quantitative real-time polymerase chain reaction was used to assess the levels of microbes including Streptococcus mutans, Streptococcus sobrinus, Lactobacillus salivarius, and Lactobacillus acidophilus in the saliva of 41 patients with a solid tumor (SO), 30 patients with a hematologic malignancy (HE), and 40 healthy controls. Salivary flow and pH were lower in oncological patients than in controls. The frequencies of all four cariogenic bacteria were highest in the SO group. S. mutans and L. salivarius were the most commonly detected in all three study groups. Mean numbers of S. sobrinus and L. salivarius in the SO group were significantly higher than in controls (p<0.05). There were no significant differences between patients and controls with respect to mean numbers of S. mutans and L. acidophilus in saliva. However, the proportions of S. mutans, S. sobrinus, and L. salivarius versus total bacteria in the SO group were significantly higher than in controls. Within patients, both mean numbers and the proportions of S. mutans and S. sobrinus were significantly different (p<0.05). In summary, significant differences were found in salivary pH values and the levels of S. mutans, S. sobrinus, and L. salivarius between SO patients and healthy controls.

BACKGROUND: Multiple Antigen Simultaneous Test (MAST)-immunoblot assay is a practical and economical test, which has been recently introduced nationwide. Authors investigated test efficiency of a MAST-immunoblot assay, Polycheck Allergy (PA). METHODS: A total of 3,153 patients were tested by PA and the results were compared with the results of ImmunoCAP and skin prick test (SPT) in 532 and 75 patients, respectively. The correlation with the lgE results measured by VIDAS was also analyzed. RESULTS: The agreements of PA with SPT were 87.8% in the Inhalant Panel and 89.3% in the Food Panel and the agreement of ImmunoCAP with SPT was 95.2%. The most common allergens giving positive reactions were Dermatophagoides farinae (46.2%) and Dermatophagoides pteronyssinus (40.0%). SPT taken as a reference, PA compared with ImmunoCAP showed higher agreement (D. farinae, 76.0 vs. 70.7%; D. pteronyssinus, 76.0 vs. 74.4%), sensitivity (D. farinae, 72.7 vs. 68.2%; D. pteronyssinus, 75.0 vs. 71.2%) and specificity (D. farinae, 85.0 vs. 81.3%) except for the specificity for D. pteronyssinus (78.3 vs. 87.5%). The rate of allergen specific IgE positive patients was higher than that of negative patients when total IgE was over 100 kU/L. CONCLUSIONS: Our results showed that the agreement, sensitivity and specificity of PA were similar to or better than those of the previously established test, ImmunoCAP. The allergen specific IgE results of PA were in correlation with total IgE. PA may be used for testing allergen specific IgE to diagnose and treat allergic diseases.

PURPOSE: This study was conducted to investigate factors related to middle-aged women's health beliefs and their intention to practice health behaviors for preventing and improving hypertension. METHODS: The participants were 319 middle-aged(40-59 years) women who lived G city. Data was collected from January to February, 2005. Personal interviews were performed. The data was analyzed using t-test, ANOVA, Scheffe's multiple comparison test and hierarchial multiple regression analysis. RESULTS: Perceived susceptibility of health belief was high in those who had higher educational level, disease history and health education experience, significantly(p<0.05). Perceived seriousness was high in those who had higher educational level, middle economic status and health education experience, significantly(p<0.05). Perceived benefits was high in those who had higher educational level and perceived barriers was low in those who had disease history and hypertension, significantly(p<0.05). The subject's intention to practice health behaviors was significantly high in those who were younger, who had higher educational level and menopausal status(p<0.05). In hierarchial multiple regression analysis, the subject's intention was related to perceived seriousness, perceived benefit and educational level, significantly(p<0.05). CONCLUSION: It is necessary to develope the education programs which can increase the subject's health belief and intention to practice health behaviors towards hypertension in middle-aged women.

PURPOSE: The purpose of this study was to develop a Problem-Based Learning (PBL) package, test its application and evaluate students' recognition of the effectiveness of PBL in nursing colleges. METHOD: Thirteen steps were used in the process developing the PBL package. After its application, the first questionnaire for self-evaluation and satisfaction with PBL class was given to 94 nursing students in December, 2005. To further evaluate the students' recognition of the effectiveness of PBL, a second questionnaire was given to 83 nursing students out of the 96 in May, 2007 after clinical practice. Data analysis was conducted using means with standard deviation. RESULTS: The results of students' self-evaluation showed high achievement in learning outcome and process using the PBL method. Also, they expressed satisfaction with the subject management, the lecturer and their peers after the PBL class. Students recognized that the PBL class had positive effectiveness in clinical practice and wanted more PBL classes and the inclusion of complex cases from well designed packages. CONCLUSION: PBL class could be considered as an opportunity to fortify student nurses' abilities to adjust to the real clinical situation.

The purpose of this study was to evaluate the apical sealing ability of Super-EBA, MTA and Dyract-flow as retrofilling materials. Forty-eight extracted human teeth with straight and single root canal were used in this study. The root canals were prepared to a #40 apical canal size and obturated with gutter-percha. Apicoectomies were performed and root end cavities were prepared to a depth of 3mm using an ultrasonic device. The root end cavities were filled with Super-EBA, MTA or Dyract-flow. Leakage was measured using an electrochemical technique for 4 weeks. According to this study, the results were as follows. 1. Increasing leakage with time was observed in all groups. 2. No significant difference was noted among the 3 groups with time (p = 0.216). 3. No significant difference was noted among the 3 groups when measured within the same time interval (p = 0.814). The results of this study suggest that the sealing ability of Dyract-flow is equal to that of Super-EBA and MTA, and Dyract-flow may be an alternative to other materials for root-end filling.

PURPOSE: Our study aimes to examine the outcome of open fractures with associated vascular injury and to assess the diagnostic value of angiography in patients who visit the emergency department (ED). METHODS: The records of 22 patients who were diagnosed as open fracture in the ED of Inha University Hospital between June 1996 and December 2001 were selected for review. Angiography was done on the suspicion of vascularinjury for patients with abnormal vascular examination results and an unclear level of injury that might require vascular repair. RESULTS: There were 21 men and one woman with a mean age of 37 years. The injury resulted from traffic accidents in 59.2% of the patients. The femur and tibia were most commonly involved and the popliteal artery was too. 18 patients were confirmed vascular injury by angiography (81.8%). 14 abnormal angiographic findings were found in 15 (93.3%) of the patients who were predicted the vascular injury by clinical findings. 4 abnormal angiographic findings were found in 7 (57.1%) of the patients who were not predicted the vascular injury. The group of patients who had demonstrated vascular injury and repair was performed within 6 hours of injury showed lesser incidence of complication than 6 hours after injury. The overall amputation rate was 22.7% (5 of 22). CONCLUSION: The most important factor in successful management is early recognition and early repair of vascular injury in open fracture. In conclusion, we suggest that emergency angiography is valuable diagnostic procedures for patients who visit the emergency department with the open fracture.
