Relationships among Depression, Self-rated Health, Health Behaviors and Drug Abuse by Job Status / 한국직업건강간호학회지

PURPOSE: This study was performed to investigate the present condition of drug abuse and its association with depression, self-rated health and health behaviors by job status in Korean adults. METHODS: Data were derived from the study on four addiction problem and suicide in 2014. Multiple logistic regression was used to analyze patterns of drug abuse according to depression, self-rated health and health behaviors. RESULTS: The prevalence of drug abuse during the past year was 17.1% of the 4,018 subjects. About 3.3 times risk for drug abuse was found among individuals who had high depression scores. The risk of drug abuse was higher among those who were smoking (OR:1.46, 95% CI:1.17~1.83), drinking more frequently (OR:1.30, 95% CI:1.07~1.58), sleeping insufficiently (OR:1.31, 95% CI:1.03~1.67), eating irregularly (OR:1.45, 95% CI:1.19~1.76). Drug abuse problem was detected more seriously among employed than unemployed adults. CONCLUSION: Health-related behaviors, such as smoking, drinking, sleeping, eating should be considered simultaneously when designing strategies to deal with drug abuse problem, and it is important to understand the interaction between drug abuse and mental health. Furthermore, workplace based intervention can be effective in solving drug abuse problem.

Complete Septal Extension Graft using Porous High-Density Polyethylene Sheet or Septal Cartilage in Unilateral Cleft Lip Nasal Deformities: Photogrammetric Analysis

PURPOSE: Complete septal extension grafts have been widely used in rhinoplasty for effective projection of the short retruded columella in Asian patients. Autologous septal cartilages and porous high-density polyethylene sheets are frequently used as septal extension grafts. This study was conducted to compare the postoperative results of porous polyethylene sheets and septal cartilages used for correction of unilateral cleft lip nasal deformities by using photogrammetric analysis. METHODS: This study investigated a total of 49 patients with cleft lip nasal deformities who underwent corrective surgery, and were followed up for at least 6 months. Septal cartilages were used in 39 patients, and porous polyethylene sheets were used in 10 patients. In all patients, through the open rhinoplasty, complete septal extension grafts were sutured to the caudal margin of the septal cartilage, and the alar cartilage was sutured with suspension. The cleft side alar cartilage was overcorrected by approximately 3 - 5 mm. Postoperative outcomes were evaluated by using photogrammetric analysis. Five indices and 4 angles were measured on their photographs taken before and after the surgery. In patients with unilateral cleft lip nasal deformities, symmetry was also evaluated by means of columellar length index. RESULTS: The postoperative values obtained in photogrammetric analysis showed improvements in comparison with the preoperative ones. The polyethylene group produced more improved outcomes than the septal cartilage group but also resulted in more complications at the same time. CONCLUSION: The results of this study indicates that complete septal extension grafts are efficient for the correction of unilateral cleft lip nasal deformities. However, since postoperative complications occur more frequently in the polyethylene group than in the septal cartilage group, caution is advised in using porous high-density polyethylene sheets in patients with cleft lip nasal deformities.

Usefulness of Breath-hold T2-w d T2-weighted MR Imaging in Patients with Myocardial Infarction: Comparison with Delayed Enhancement

PURPOSE: To evaluate the usefulness of breath-hold T2-weighted MR imaging in patients with myocardial infarction. MATERIALS AND METHODS: We investigated 11 patients with myocardial infarction who shown delayed enhancement on MR imaging. Infarcted myocardium on T2-weighted MR imaging was classified as high, iso, and low signal area comparing with normal myocardium. The intensity and transmural extent of infracted myocardium was also analyzed. On the basis of clinical information, the stage of infracted myocardium on T2-weighted MR imaging was assessed. RESULTS: It was observed high signal area in 12 segments of 5 patients, low in 12 segments of 6 patients on T2-weighted MR imaging. The high signal intensity of infarcted myocardium was shown as 175+/-9% comparing with that of the normal myocardium, low signal intensity as 73+/-5% (p < 0.05). In the evaluation of transmural extent, the high signal areas on T2-weighted MR imaging were larger than infarct area on delayed enhancement imaging (100% vs. 49%+/-17%), whereas low signal areas on T2-weighted MR imaging correlated. High signal area was visualized on T2-weighted MR imaging within 11days, whereas low-signal area was seen after 7 months. CONCLUSION: Breath-hold T2-weighted MR imaging is useful in the evaluation of stage as well as edema and fibrous scar in patients with myocardial infarction.
