Purpose: NTM (non tuberculous mycobacteria) is rare cause of surgical site infection after plastic surgery in immunocompetent patients. There are some reports about NTM infection after body contouring procedure from Latin America. But, there is no report in Korea. The purpose of this article is to report 2 patients with soft tissue infection caused by NTM after body contouring procedure. Methods: Two young female patients exhibited signs of inflammation and abscess after body contouring procedure. One patient underwent liposuction. The other underwent HPL (hypotonic pharmacologic lipo-dissolution) injection. Results: The result of tissue cultures were positive for NTM. All patients responded to the combined therapeutic approach. Conclusion: The goal of this article is to raise awareness among plastic surgeons who may encounter such patients in their practice. NTM should be included in the differential diagnosis of surgical site infection after body contouring surgery.

Background: Transcutaneous Electrical Nerve Stimulation (TENS) has been widely used for pain relief after surgery instead of opioid analgesics therapy. This study was designed to study the effectiveness of TENS on perianal pain after anal surgery. Methods: Forty-eight patients who underwent anal surgery were evaluated in this suudy. Caudal anesthesia with 1.5% lidocaine 30 ml mixture 1：200,000 epinephrine was performed. TENS was done at 100 Hz for 25 min. duration, postoperatively at 4 hrs and 24 hrs. Pain was also measured at the 4 hrs and 24 hrs postoperatively by visual analogue scale (VAS). VAS value were compared before and after TENS application. Results: Values of VAS after TENS were significantly lower compared to those before TENS. Conclusions: From these results, we concluded, TENS may be effective for postoperative perianal pain relief after anal surgery.

The intracranial hemorrhage in regions remote from the site of initial operations is unusual but may present as fatal surgical complication. We report a rare case of multiple, sequential, remote intracranial hematomas after cranioplasty in a patient who did not have any prior risk factors. A 51-years-old man was transferred to the hospital after a head trauma. The brain computed tomography (CT) revealed acute subdural hemorrhage on the right hemisphere with prominent midline shifting. After performing decompressive craniectomy and hematoma removal, the patient recovered without any complications. However, the patient showed neurological deterioration immediately after cranioplasty, which was done three months after the first surgery. There was extensive hemorrhage in the posterior fossa remote from the site of the initial operation site. The brain CT taken soon after removing this hematoma evacuation displayed large epidural hematoma on the left hemisphere. This case represents posterior fossa hemorrhage after supratentorial procedure and sequential delayed hematoma on the contralateral supratentorial region thus seems very rare surgical complications. Despite several possible pathogenetic mechanisms for such remote hematomas, there are usually no clear cut relationships with each case as in our patient. However, for the successful outcome, prompt evaluation and intensive management seem mandatory.

Objectives: This study sought to evaluate trabecular changes in the mandible using fractal analysis and to explain the transient osteopenia related to rapid orthodontic tooth movement after orthognathic surgery. Materials and Methods: Panoramic radiographs were taken of 26 patients who underwent bilateral sagittal split ramus osteotomy. Radiographs taken before the surgery and 1 month after surgery were overlapped, and $40{\times}40$ pixel square regions of interest were selected near the mandibular canines and 1st molars. After the image processing procedure, the fractal dimension was calculated using the box-counting method. Results: Fractal dimension after orthognathic surgery decreased in a statistically significant manner (P<0.05). The change in fractal dimension on the canine side had greater statistical significance as compared to that seen on the 1st molar side. Conclusion: This study found that bone density decreases after orthognathic surgery due to transient osteopenia related to the regional acceleratory phenomenon. This result can provide a guide to evaluating orthodontic tooth movement after orthognathic surgery.

Purpose: This study was to examine the changes in knowledge, attitudes, and preventive behaviors among elementary school students after providing them with tuberculosis prevention education. Methods: A total of 235 students from D elementary school in G city were selected. After completing tuberculosis prevention education, the subjects were surveyed five times for 16 weeks. 1,087 samples were included in the final analysis. One-way ANOVA, $Scheff{\acute{e}$'s test, Pearson's correlation, and multiple regression analysis were performed to examine the changes in tuberculosis-related knowledge, attitudes and preventive behaviors over time. Results: After 16 weeks from the education, the scores of preventive behaviors did not show any significant difference compared to the time right after the education. However, the scores of knowledge and attitudes tended to improve. In particular, 1st~2nd graders had high scores in both knowledge and attitude, and the scores of knowledge and attitude gradually increased over time. The correlation between knowledge, attitude, and preventive behavior regarding tuberculosis had a positive significance during the entire time of the survey. Conclusion: Positive associations between knowledge and attitude and between attitude and preventive behavior sustained for 16 weeks after tuberculosis education among elementary school students. This study suggests that tuberculosis prevention education conducted early on from lower grades can produce more educational effects and that it could be a foundation not only for developing knowledge of tuberculosis but also for cultivating adequate attitudes and forming active tuberculosis preventive behaviors.

Elementary school education in Korea has been constantly changing according to the requirements of social change. Contemporary primary education is oriented creative-education and institutional changes were required. As a result, it is appearing movement wants to get out of uniform curriculum of elementary school. This paper was carried out to analyze after-school programs other than the curriculum of elementary education school and to analyze the current status of the space use of school facilities. Based on this analysis, it is proposed utilization of spatial association between the elementary school and local public facilities.

Purpose: Endoscopic diagnosis of gastric cancer (GC) that emerges after eradication of Helicobacter pylori may be affected by unique morphological changes. Using comprehensive endoscopic imaging, which can reveal biological alterations in gastric mucosa after eradication, previous studies demonstrated that Congo red chromoendoscopy (CRE) might clearly show an acid non-secretory area (ANA) with malignant potential, while autofluorescence imaging (AFI) without drug injection or dyeing may achieve early detection or prediction of GC. We aimed to determine whether AFI might be an alternative to CRE for identification of high-risk areas of gastric carcinogenesis after eradication. Materials and Methods: We included 27 sequential patients with metachronous GC detected during endoscopic surveillance for a mean of 82.8 months after curative endoscopic resection for primary GC and eradication. After their H. pylori infection status was evaluated by clinical interviews and $^{13}C$-urea breath tests, the consistency in the extension of corpus atrophy (e.g., open-type or closed-type atrophy) between AFI and CRE was investigated as a primary endpoint. Results: Inconsistencies in atrophic extension between AFI and CRE were observed in 6 of 27 patients, although CRE revealed all GC cases in the ANA. Interobserver and intraobserver agreements in the evaluation of atrophic extension by AFI were significantly less than those for CRE. Conclusions: We demonstrated that AFI findings might be less reliable for the evaluation of gastric mucosa with malignant potential after eradication than CRE findings. Therefore, special attention should be paid when we clinically evaluate AFI findings of background gastric mucosa after eradication (University Hospital Medical Information Network Center registration number: UMIN000020849).

Purpose: This study aimed to assess the three-dimensional (3D) facial changes after orthognathic surgery by evaluating the spherical coordinates of facial lines using 3D computed tomography (CT). Materials and Methods: A 19-year-old girl was diagnosed with class III malocclusion and facial asymmetry. Orthognathic surgery was performed after orthodontic treatment. Facial CT scans were taken before and after orthognathic surgery. The patient had a menton deviation of 12.72 mm before surgery and 0.83 mm after surgery. The spherical coordinates of four bilateral facial lines (ramal height, ramal lateral, ramal posterior and mandibular body) were estimated from CT scans before and after surgery on the deviated and opposite side. Results: The spherical coordinates of all facial lines changed after orthognathic surgery. Moreover, the bilateral differences of all facial lines changed after surgery, and no bilateral differences were zero. Conclusion: The spherical coordinate system was useful to compare differences between the presurgical and postsurgical changes to facial lines.
