ABSTRACT
Purpose@#This study examined the effects of a physical activity promoting program based on the Information-Motivation-Behavioral Skills (IMB) model on physical activity and health outcomes among obese older adults with knee osteoarthritis. @*Methods@#This study utilized a randomized controlled trial with a convenience sample of 75 obese older adults with knee osteoarthritis in a university hospital. The older adults in the intervention group participated in a 12-week program involving weekly group sessions and monitoring calls with education booklets and video clips for exercise dances, while those in the control group received an usual care. Outcomes were measured using self-report questionnaires, anthropometrics, and blood analyses. The intervention effects were analyzed using Mann-Whitney U test and ANCOVA. @*Results@#The mean age of participants was 74.9 years with 84.0% women. The intervention group at 12 weeks showed significantly greater improvements in self-efficacy for physical activity (F=81.92, p <.001), physical activity amounts (Z=-2.21, p =.044), knee joint function (F=15.88, p <.001), and health-related quality of life (F=14.89, p <.001) compared to the control group. Among obese-metabolic outcomes, the intervention group at 12 weeks showed a significant decrease in visceral fat mass (F=7.57, p =.008) and improvement in high-density level cholesterol (F=9.51, p =.003) compared to the control group. @*Conclusion@#Study findings support the need for an IMB based physical activity program for promoting physical activity, knee function and health outcomes in obese older adults with knee osteoarthritis. Longitudinal studies are warranted to confirm the persistence of obese-metabolic effects in clinical settings.
ABSTRACT
Purpose@#The aims of this study were (1) to investigate the relationship between the characteristics of allogenic bone block and the compressive strength of an allogenic bone block measured by biomechanical experiments, and (2) to compare the maximum pressure load of allogenic bone block with the gap pressure measured at the high tibial opening osteotomy. @*Materials and Methods@#Ten patients who provided informed consent for gap pressure measurements during opening wedge high tibial osteotomy (OWHTO) were included. The gap pressures were measured at 1 mm intervals while opening the osteotomy site from 8 mm to 14 mm. Seventeen U-shaped allogenous wedge bone blocks were made from the femur, tibia, and humerus. The height, width, cross-sectional area, and cortex thickness of the bone blocks were measured, along with the maximum compressive load just before breakage. The relationship between these characteristics and the maximum pressure load of the bone blocks was evaluated. The gap pressures measured in OWHTO were compared with the maximum pressure loads of the allogenous wedge bone blocks to evaluate the possibility of inserting allogenous wedge bone blocks into the osteotomy site without a distractor in OWHTO. @*Results@#The OWHTO gap pressure increased with increasing osteotomy site opening. The mean gap pressure, which occurred at a 14-mm opening, was 282±93 N; the maximum pressure was 427 N. The maximum pressure load of the allografts was 13,379±6,469 N (minimum, 5,868; maximum, 29,130 N) and was correlated significantly with the cortical bone thickness (correlation coefficient=0.693, p=0.002) and cross-sectional area (correlation coefficient=0.826, p<0.001). Depending on the sterilization method, the maximum pressure loads for the bone blocks were 13,406±5,928 N for freeze-dried and 13,348±7,449 N for fresh frozen. The maximum compressive load of the allogenous wedge bone blocks was 13.7-times greater than that in OWHTO opened to 14 mm (5,868 N vs. 427 N). @*Conclusion@#The compressive strength of allogenous wedge bone blocks was sufficiently greater than the gap pressure in OWHTO. Therefore, allogenous wedge bone blocks can be inserted safely into the osteotomy site without a distractor.
ABSTRACT
Tuberculosis of parotid gland is extremely rare, even in countries where tuberculosis is endemic. It can occur by systemic dissemination from a distant focus or as primary involvement. Because of the clinical and radiological similarity, parotid tumor and parotid inflammatory disease take priority over the tuberculosis of parotid when it comes to differential diagnosis. As a result, clinicians often fail to make a timely diagnosis of tuberculosis of parotid gland in patient with a slowly growing parotid mass. However, its treatment is primarily medical if the positive diagnosis is well established. We have recently experienced a case of tuberculosis of parotid gland that was considered as the benign tumor preoperatively, but which was confirmed as tuberculosis of parotid gland after extracapsular dissection. We report it with a review of literature.

ABSTRACT
The ‘white-eyed’ blowout fracture is an orbital injury in children that is often initially misdiagnosed as a head injury because of predominant autonomic features and lack of soft tissue signs. Delays in treatment can lead to morbidity. It has been recommended that children who present with a ‘white-eyed’ blowout fracture should have surgery performed within 48 hours of diagnosis, otherwise prognosis is poor. We present a 12-year-old boy who was initially misdiagnosed with a head injury due to the minor appearance of his orbital injury and his presenting complaints of nausea and vomiting.

ABSTRACT
Bilateral chylothorax due to blunt trauma is extremely rare. We report a 74-year-old patient that developed delayed bilateral chylothorax after falling off a ladder. The patient had a simple 12th rib fracture and T12 lamina fracture. All other findings seemed normal. He was sent home and on the 5th day visited our emergency center at Halla Hospital with symptoms of dyspnea and lower back pain. Computer tomography of his chest presented massive fluid collection in his right pleural cavity and moderate amounts in his left pleural cavity with 12th rib fracture and T11-12 intervertebral space widening with bilateral facet fractures. Chest tubes were placed bilaterally and chylothorax through both chest tubes was discovered. Conservative treatment for 2 weeks failed, and thus, thoracic duct ligation was done by video assisted thoracoscopic surgery. Thoracic duct embolization was not an option. Postoperatively, the patient is now doing well and happy with the results. Early surgical treatment must be considered in the old patient, whom large amounts of chylothorax are present.
ABSTRACT
Although hemothorax and pneumothorax are common complications seen in rib fractures, focal extrapleural hematoma is quite rare. We report a 63-year-old female patient that developed large focal extrapleural hematoma after falling off a second floor veranda. The patient had sustained 3, 4, 5th costal cartilage rib fractures and a sternum fracture. She had developed suspected empyema with loculations with small amount of hemothorax. She underwent a planned early decortication/adhesiolysis by video assisted thoracoscopic surgery at the 12th post-trauma day due to failed drainage. Unexpectedly, she had no adhesions or any significant retained hematoma mimicking a mass, but was found with the focal extrapleural chest wall hematoma. She was discharged on postoperative 46th day for other reasons and is doing fine today.
ABSTRACT
Korea is one of the fastest aging country in the world. As the old population increases, incidence of stroke would rapidly increase. We estimated future of the neurologist supply in Korea, and assessed whether the present neurologist supply is appropriate to cope with future increase of stroke. We reviewed the resource database of neurologists affiliated to Korean Neurological Association. Age, sex, location of workplace, and work positions were identified. The stroke incidence was calculated from age group specific incidence data and projected age group number. Age group specific incidence data was adapted from the 2006 report of the Construction of National Surveillance System for Cardiovascular and Cerebrovascular Disease. Total 1,828 neurologists in practice were identified. Six hundred and fifty-five (30%) worked in training hospitals. 457 (21%) in other general hospitals, 305 (14%) in private clinics, and 148 (7%) worked in nursing hospitals. Assuming that the neurologists are trained 82 people per year as in the present, 2,073 neurologists would be present in 2020, 2,659 in 2030. However, stroke incidence would show more rapid increment, and is expected about 170,000 per year in 2020 and 300,000 per year in 2030. Therefore, there will be a shortage of neurologists needed for stroke care in the future. Because of rapid increase in the elderly population, current supply of neurologists may not meet the expected need for stroke care. Therefore, national health system needs more neurologists to cope with that situation.

Rib fixations for flail chest or displaced rib fractures are not a new technique. However, reports on rib fixations involving costal cartilage fractures are very few and surprisingly there are no reports of internal fixations involving only the costal cartilage in the English literature. The diagnosis is difficult and the necessity of the procedure may be quite controversial. Placing plates in screws into the costal cartilage alone may seem unstable and easily dislodged or stripped through the cartilage. We report a 31-year-old male scuba diver instructor who underwent rib fixations over his 7th and 8th costal cartilage ribs for severe pain. The procedure was done with conventional plates and screws. He had the plates and screws removed 2 months later due to lingering pain, but with them removed he is now quite happy with the results without pain. The procedure for fixation of painful overlapped costal cartilage is quite simple and can be done with the usual conventional methods, fixating plate and screws directly over the cartilage alone without fixation over the bony rib.
ABSTRACT
Delayed esophageal rupture due to blunt injury is not new. However, rupture due to suspected barotrauma is very rare. We describe a case of esophageal rupture in a male 24-year-old patient after diving in shallow waters. The patient was quadriplegic and could not experience the typical chest pain related to rupture and resulting mediastinitis. The rupture was discovered 4 days after emergency decompressive laminectomy and fusion for his cervical spine. The rupture was evidently caused by barotrauma and was discovered four days after admission. He underwent primary closure and pericardial flap as a life-saving procedure.
ABSTRACT
Osteoblastoma is a rare benign tumor, representing less than 1% of all bone tumors. Most cases occur in the vertebrae and in the long bones. Intranasal or paranasal osteoblastoma is particularly rare and only one case of osteoblastoma in the inferior turbinate has been reported in the world literature. Treatment is intralesional curettage or en bloc resection. Since the tumor is benign, conservative surgery is curative in about 80-90% of the cases. Concha bullosa is an abnormal pneumatization of the intranasal turbinates and inferior concha bullosa is a very rare condition. We report an unusual case of osteoblastoma occurring together with inferior concha bullosa. The tumor and inferior concha bullosa were removed by endoscopic submucosal inferior turbinoplasty, with favorable results. Related articles are reviewed and brief discussions are presented in regards to the case findings.
ABSTRACT
OBJECTIVE: This retrospective, cross-sectional study aimed to establish reference data for normal crown and root lengths and the root–crown ratios (R/C ratios) for the mature maxillary and mandibular incisors in a Korean population by using cone-beam computed tomography (CBCT). METHODS: We included 672 Korean patients (141 men and 531 women; mean age, 27.2 ± 7.7 years) who underwent CBCT examinations during various dental treatments. Crown and root lengths and the R/C ratios of the maxillary and mandibular incisors were measured using CBCT data, which were analyzed to detect significant differences between demographic factors as well as sagittal and vertical skeletal or occlusal relationships. RESULTS: Teeth of the same type in each half-arch were symmetrical. The mean R/C ratios varied from 1.1 to 1.2 for the maxillary incisors and from 1.3 to 1.4 for the mandibular incisors. Crown and root lengths were greater in men than in women, regardless of tooth type. Root lengths and R/C ratios for the mandibular incisors were significantly greater in patients with skeletal Class II malocclusion or an excessive overjet than in the other patients. The R/C ratios for the mandibular incisors were lower in patients with an open bite than in those with a normal or deep bite. Moreover, the R/C ratios for the mandibular incisors increased with age. CONCLUSIONS: The data obtained in our study can serve as reference values for crown and root lengths and the R/C ratios for the maxillary and mandibular incisors in the Korean population.

OBJECTIVE: The aims of this study were to assess the direction and degree of lip-line cant in Korean adult orthodontic patients and to identify the effects of sex and age on changes in the cant severity. METHODS: In this cross-sectional retrospective study, lip-line cant was measured in the frontal photographs of 585 Korean patients (92 men and 493 women) aged 18-48 years. The outcome variables (direction and degree of lip-line cant) were assessed in terms of predictor variables (sex, age, sagittal skeletal relationship, and menton deviation angle). RESULTS: The direction of lip-line cant did not differ according to sex, age, or skeletal classification. Patients had 1.6° of lip-line cant on average before orthodontic treatment. Middle-aged adults displayed a significant trend toward a lower degree of lip-line cant compared to younger adults (p < 0.01). Multiple linear regression analysis showed that the degree of lip-line cant was weakly negatively correlated with age (p < 0.001). CONCLUSIONS: While the direction of lip-line cant did not differ according to the parameters explored here, the degree of cant was correlated with age in adults, independent of menton deviation. Specifically, middle-aged adults tended to display significantly lower degrees of lip-line cant than did younger adults.

PURPOSE: This study examined association of job stress with health-promoting behaviors and objective health status in 129 clinical nurses working at a university hospital. METHODS: A cross-sectional and descriptive design was used. Job stress and health behaviors were measured with Korean Occupational Stress Scale and Heath Promoting Lifestyle Profile-II, respectively. Health status measured with afternoon plasma cortisol, C-peptide, and lipid profiles. RESULTS: The level of job stress among clinical nurses was moderate with 51.41 on average. The mean for health-promoting behavior in the low stress group was significantly higher than that in the high or moderate stress groups (p<.001). The proportions of nurses with high C-peptide and cortisol levels, or low high-density lipoprotein levels, ranged from 14.0% to 35.7%. In particular, the percentage of nurses with high C-peptide levels was significantly higher in moderate and high stress groups than in the low stress group (24.1% versus 11.6%, p<.05). CONCLUSION: The study findings affirmed the associations of job stress with health-promoting behaviors as well as selected health status indicators such as C-peptide in clinical nurses. Job stress management intervention can help clinical nurses to improve their health-promoting behaviors and health status.

BACKGROUND AND OBJECTIVES: Typically, posterior epistaxis means that the bleeding point cannot be visualized with anterior rhinoscopy, and it is difficult to find a localized bleeding point. Although bleeding point identification is the key to efficient management, debate and uncertainty remain around the actual location and distribution of the bleeding sites in posterior epistaxis. SUBJECTS AND METHOD: This study was designed to clarify bleeding points of the posterior epistaxis using nasal endoscopy. In 121 of the total 150 (80.7%) cases, we could see the posterior nasal cavity in more detail and find the bleeding point precisely. RESULTS: The most common sites of the bleeding were the posterior portion of the inferior meatus, the posterior portion of middle meatus, and the posterior septum medial to the middle turbinate in order of frequency. A total of 113 cases, corresponding to 93.4% (113/121), showed that epistaxis could be controlled very efficiently by electrocauterization and localized small packing with the help of endoscopes. In the majority of cases, non-surgical interventions were sufficient. CONCLUSION: Bleeding could be stopped more rapidly and with less discomfort if checking the 3 most common sites early.

Compartment syndrome is caused by elevated pressure in a restricted compartment. It typically occurs after fractures of the extremities and usually has an acute clinical progression. Chronic compartment syndrome is another relatively well known form, typically associated with forceful exercise. Also, there are various reports of compartment syndrome not associated with typical causes. However, reports on compartment syndrome with unknown etiology are rare and there has been none in Korean literature. We report a case of compartment syndrome with no recognizable cause, hence classified as idiopathic.

OBJECTIVE: The aim of this study was to compare the success rates of the manual and motor-driven mini-screw insertion methods according to age, gender, length of mini-screws, and insertion sites. METHODS: We retrospectively reviewed 429 orthodontic mini-screw placements in 286 patients (102 in men and 327 in women) between 2005 and 2010 at private practice. Age, gender, mini-screw length, and insertion site were cross-tabulated against the insertion methods. The Cochran-Mantel-Haenszel test was performed to compare the success rates of the 2 insertion methods. RESULTS: The motor-driven method was used for 228 mini-screws and the manual method for the remaining 201 mini-screws. The success rates were similar in both men and women irrespective of the insertion method used. With respect to mini-screw length, no difference in success rates was found between motor and hand drivers for the 6-mm-long mini-screws (68.1% and 69.5% with the engine driver and hand driver, respectively). However, the 8-mm-long mini-screws exhibited significantly higher success rates (90.4%, p < 0.01) than did the 6-mm-long mini-screws when placed with the engine driver. The overall success rate was also significantly higher in the maxilla (p < 0.05) when the engine driver was used. Success rates were similar among all age groups regardless of the insertion method used. CONCLUSIONS: Taken together, the motor-driven insertion method can be helpful to get a higher success rate of orthodontic mini-screw placement.

PURPOSE: This study was to develop and evaluate a health promotion program for women with osteoarthritis. METHODS: The research adopted the nonequivalent control group pretest-posttest design. The subjects were 34 in the experimental group and 34 in the control group sampled among vulnerable women aged over 40. The independent variable was the health promotion program, and the dependent variables were perceived health status, balance, K-WOMAC, depression, life satisfaction and health promoting behavior. The health promotion program was performed for 50minutes each session, twice a week and for 8 weeks. Data were collected from July 1 to September 11, 2010. RESULTS: The experimental group showed significant differences in perceived health status, balance, WOMAC pain, WOMAC difficulty of performing activity, depression, and health promoting behavior compared to the control group. There was no significant difference in WOMAC stiffness, waist, weight, and life-satisfaction. CONCLUSION: The results of this study suggest that the health promotion program can be applied in degenerative arthritis education to improve self-care.
