Objectives: This study aimed to establish a single-session associative protocol for nonrestorative management of dentin hypersensitivity (DH). Materials and Methods: Twenty-four individuals with DH and a minimum sensitivity level of 4 on the visual analog scale (VAS) were selected. The study was conducted in a split-mouth design, with each participant (n = 20) having at least 1 affected tooth in all quadrants. The management protocols consisted of control group: universal adhesive, Neural Desensitizing Protocol group: 5% potassium nitrate, Mixed Desensitizing Protocol (PAM) group: 5% sodium fluoride and 5% potassium nitrate, Remineralizing Desensitizing Protocol (PDR) group: surface-partially reacted glass technology photopolymerizable varnish. Evaluations were performed immediately after application, at 1 week, 1 month, 2 months, and 12 months using the VAS sensitivity test. Results: The scores were subjected to statistical analysis using the Friedman test (p < 0.05), Durbin-Conover test (p < 0.05), and Wilcoxon test (p < 0.05). At the 12-month evaluation, all groups showed statistically significant differences compared to the initial assessment. For the evaluation after 12 months, there was a statistically significant difference between the PAM group, the control group, and the PDR group. Conclusions: It can be concluded that all groups were effective in controlling DH, but there were significant results in the control group and PDR group. The clinical relevance of this study is to demonstrate that the application of single-session desensitizing protocols can be effective in controlling DH for up to 12 months.

Purpose: Clinical stage of gastric cancer is currently assessed by computed tomography. Accurate clinical staging is important for the tailoring of therapy. This study evaluated the accuracy of clinical N staging using stomach protocol computed tomography. Materials and Methods: Between March 2004 and November 2012, 171 patients with gastric cancer underwent preoperative stomach protocol computed tomography (Jeju National University Hospital; Jeju, Korea). Their demographic and clinical characteristics were reviewed retrospectively. Two radiologists evaluated cN staging using axial and coronal computed tomography images, and cN stage was matched with pathologic results. The diagnostic accuracy of stomach protocol computed tomography for clinical N staging and clinical characteristics associated with diagnostic accuracy were evaluated. Results: The overall accuracy of stomach protocol computed tomography for cN staging was 63.2%. Computed tomography images of slice thickness 3.0 mm had a sensitivity of 60.0%; a specificity of 89.6%; an accuracy of 78.4%; and a positive predictive value of 78.0% in detecting lymph node metastases. Underestimation of cN stage was associated with larger tumor size (P<0.001), undifferentiated type (P=0.003), diffuse type (P=0.020), more advanced pathologic stage (P<0.001), and larger numbers of harvested and metastatic lymph nodes (P<0.001 each). Tumor differentiation was an independent factor affecting underestimation by computed tomography (P=0.045). Conclusions: Computed tomography with a size criterion of 8 mm is highly specific but relatively insensitive in detecting nodal metastases. Physicians should keep in mind that computed tomography may not be an appropriate tool to detect nodal metastases for choosing appropriate treatment.

Purpose: It is crucial to provide adequate enteral nutrition for postoperative recovery, wound healing and normal growth in infants in pediatric cardiac ICUs. This study was done to develop a feeding protocol using the vaso-active inotropic (VAI) score and to evaluate the impact of nutritional outcomes following the new feeding protocol for infants who underwent cardiac surgery. Methods: This study consisted of three phases. First, a feeding protocol was developed based on a literature review. Second, ten experts rated the content validity. Third, a comparison study was conducted to evaluate the impact of the new feeding protocol. Data were analyzed using SPSS Version 20. Results: Twenty-nine infants were enrolled in the pre-protocol group, and 22 infants in the post-protocol group. Patients in the 2 groups were similar. Time to reach feeding goal was significantly decreased from 56.0 (27-210) hours to 28.5 (10-496) hours in the post-protocol group (Z=-4.22, p<.001). Level of enteral feeding knowledge among nurses increased significantly after implementation of the protocol. Conclusion: The feeding protocol using VAI score facilitates the achievement feeding goal to decrease feeding interruptions and help nurses in their practice. Larger studies are necessary to examine clinical outcomes following the implementation of this feeding protocol.

Purpose: Concept analysis was performed on the behavioral concept of endotracheal suctioning (ETS), to identify the goal, to develop astandardized clinical protocol, to identify the antecedents and consequences, and to differentiate the improper use of ETS. Method: Walker & Avant's concept analysis was employed using clinical guidelines, books and review articles in which the procedures of ETS were written in detail and published in Pubmed within the last 20 years. Result: The macro-goal of ETS was to remove accumulated respiratory secretions. Three defining attributes of ETS were identified; catheter, suctioning and asepsis. Each attribute involved empirical referents, such as the size and depth of the catheter, the suction pressure, duration and method for suctioning. The antecedents of ETS were identical to the clinical evidences for the need of ETS such as the nursing assessment data. The consequences of ETS serve as an evaluation criteria on the effectsof ETS based on the goal of ETS. Conclusion: The concept analysis of ETS demonstrates an example of considering a specific nursing protocol of ETS as a behavioral concept, applying concept analysis to it to identify it's key behavioral components as defining attributes and empirical referents and then developing and applying the standard ETS protocol.

There are 82 dental hygiene departments and clinical training institutes across the country with a very wide range of clinical practice content and evaluation methods, making standardization difficult. Therefore, there is a need to establish a standard protocol outlining clinical practice content and evaluation methods for systematic and efficient operation of clinical practice. Thus, this study attempted to propose such a protocol for standardization of dental hygiene clinical practice in dental clinics and hospitals to examine the contents of clinical practice by reviewing relevant literature, and relating it to professional practice within the dental hygienic curriculum to facilitate enhancement of expertise. Clinical practice content was extracted from 74 cases, and was consisted of classifying mandatory and optional clinical practice, training time, and activity methods for each component. To standardize effective clinical practice, it is necessary to organize the components acquired in the course of clinical dentistry training in line with their arrangement on each university's curriculum, in order to learn all components step by step. To do this, it is necessary to present a standardized clinical practice protocol and a organic cooperation between educational institutions and clinical training institutions.
