PURPOSE: This study was done to develop a risk behavior scale for Korean middle school adolescents. METHODS: The process included construction of a conceptual framework, initial items, verification of content validity, selection of secondary items, and extraction of final items. The participants were 717 adolescents from six middle schools in three cities. Item analysis, factor analysis, criterion validity, and internal consistency were used to analyze the data. RESULTS: Fifty seven items were selected for the final scale, and categorized into 4 factors explaining 48.11% of total variance. The factors were labeled as latent problem behavior (38 items), suicidal behavior (7 items), runaways (3 items), and internet negative use (9 items). The scores for the scale were significantly correlated with crisis. Cronbach's alpha coefficient for the 57 items was .92. CONCLUSION: The above findings indicate that the risk behavior scale has good validity and reliability when used with Korean middle school adolescents.

PURPOSE: The purpose of this study was to investigate the effects of the ‘Becoming Happy I’ program on gratitude disposition, self-esteem, flow, and subjective happiness in nursing college students.METHODS: Participants in this study were 39 nursing college students (20 in the experimental group and 19 in the control group) at a college of nursing. The research design was a non-equivalent control group pretest-posttest as a quasi-experimental study. Data was collected from February to April in 2011 and analyzed via the SPSS/WIN 18.0 program with the χ² test, Fisher's exact test, repeated measures ANOVA, and Tukey HSD test.RESULTS: There were significant changes in gratitude disposition, self-esteem, flow, and subjective happiness in the experimental group before and after treatment, which was significantly different from the control group, and these effects lasted at a 4-week follow-up.CONCLUSION: The ‘Becoming Happy I’ program was effective in improving gratitude disposition, self-esteem, flow, and subjective happiness for nursing college students. As a result, we recommended that the ‘Becoming Happy I’ program be utilized as an effective intervention for nursing college students to improve gratitude disposition, self-esteem, flow, and subjective happiness.

Intradermal injections of indigo carmine for sentinel node mapping are considered safe and no report of an adverse reaction has been published. The authors described two cases of profound hypotension in women that underwent breast-conserving surgery after an intradermal injection of indigo carmine into the periareolar area for sentinel node mapping.

BACKGROUND: Laparoscopic gastrectomy requires a reverse-Trendelenburg position and prolonged pneumoperitoneum and it could cause significant changes in cerebral homeostasis and lead to cognitive dysfunction. We compared changes in regional cerebral oxygen saturation (rSO2), early postoperative cognitive function and hemodynamic variables in patients undergoing laparoscopic gastrectomy with those patients that underwent conventional open gastrectomy. METHODS: Sixty patients were enrolled in this study and the patients were distributed to receive either laparoscopic gastrectomy (laparoscopy group, n = 30) or open conventional gastrectomy (open group, n = 30). rSO2, end-tidal carbon dioxide tension, hemodynamic variables and arterial blood gas analysis were monitored during the operation. The enrolled patients underwent the mini-mental state examination 1 day before and 5 days after surgery for evaluation of early postoperative cognitive function. RESULTS: Compared to baseline value, rSO2 and end-tidal carbon dioxide tension increased significantly in the laparoscopy group after pneumoperitoneum, whereas no change was observed in the open group. No patient experienced cerebral oxygen desaturation or postoperative cognitive dysfunction. Changes in mean arterial pressure over time were significantly different between the groups (P < 0.001). CONCLUSIONS: Both laparoscopic and open gastrectomy did not induce cerebral desaturation or early postoperative cognitive dysfunction in patients under desflurane anesthesia. However, rSO2 values during surgery favoured laparoscopic surgery, which was possibly related to increased cerebral blood flow due to increased carbon dioxide tension and the effect of a reverse Trendelenburg position.

A 70-year-old woman with an infectious thrombus in her left internal jugular vein (IJV) underwent carotid endarterectomy for stenosis and a highly movable plaque in her right carotid artery. She had been treated with antibiotics for four weeks before surgery due to Lemierre syndrome, a rare septic thrombophlebitis in the IJV secondary to an oropharyngeal infection. The right IJV was in a two-fold dilated state due to compensation for a thrombotic left IJV. Accordingly, superficial cervical plexus block was performed under ultrasound guidance to ensure safety and accuracy. During surgery, the alertness was maintained and the patient did not complain of pain in the absence of additional analgesics. No block-related complications were encountered. The authors report for the first time their regional anesthetic experiences in a patient with Lemierre syndrome.

BACKGROUND: Different tidal volume (TV) settings during mechanical ventilation alter intrathoracic blood volume, and these changes could alter central venous pressure and the cross sectional area (CSA) of the right internal jugular vein (RIJV). The aim of this study was to determine the optimal TV for maximizing the CSA of the RIJV in the supine and Trendelenburg positions in anesthetized patients. METHODS: Forty patients were randomly allocated to a supine group (Group S, n = 20) or a Trendelenburg group (Group T, n = 20) by computer generated randomization. RIJV CSAs were measured repeatedly after increasing the inspiratory volume in 1 ml/kg increments from a TV of 8 ml/kg to 14 ml/kg using ultrasound images. RESULTS: Peak inspiratory pressure increased significantly on increasing TV from 11 ml/kg to 14 ml/kg and between baseline (TV 8 ml/kg) and 11 ml/kg in both groups (P < 0.05). RIJV CSA was not increased versus baseline even after TV changes in either group and no intergroup difference was found. CONCLUSIONS: TV increases do not increase the CSA of the RIJV within the TV range 8 to 14 ml/kg in the supine or 10degrees Trendelenburg position.
