Vitamin D is an important hormone that can be a role of bone and calcium metabolism in the human organ. Thus, vitamin D deficiency could contribute to the severity of metabolic bone disease. The osteomalacia, one of the metabolic bone diseases, is the softening of the bones caused by defective bone mineralization secondary to inadequate amounts of available phosphorus and calcium. We experienced a case of osteomalacia presented with walking disturbance, 30 year-old young aged man, caused by vitamin D deficiency due to strict vegetarian diet and lack of sunlight exposures.

OBJECTIVES: The purpose of this study was to examine the occupational risk factors associated with musculoskeletal symptoms in public workers. METHODS: In November 2010, 544 participants anwered a survey that included questions on the participants' general characteristics, job-related factors, health-related behaviors, and psychosocial stress. We measured the relationship of risk factors to musculoskeletal symptoms using a logistic regression analysis. RESULTS: After adjusting for general characteristics, factors associated with occupational musculoskeletal symptoms were gender (OR=2.858, 95% CI=1.701~4.801), unnatural posture (OR=2.386, 95% CI=1.308~4.354), psychosocial stress (OR=4.051, 95% CI=1.336~12.282) and sleep quality (OR=1.672, 95% CI=1.052~2.660). CONCLUSIONS: These findings suggest that psychosocial stress levels and physical environment (especially in professions requiring an unnatural posture) are related to musculoskeletal symptoms in public workers.

BACKGROUND/AIMS: Little research has been done to evaluate the effect of stress in exacerbating the symptoms associated with gastroesophageal reflux (GER). We aimed to investigate the effect of acute stress on esophageal motility and GER parameters in healthy volunteers. METHODS: A total of 10 (M:F = 8:2, median age 34 years-old) healthy volunteers without any recurrent gastrointestinal symptoms participated in this study. They underwent esophageal high-resolution manometry with 10 wet swallows (Experiment I) and esophageal impedance-pH monitoring (Experiment II) in the basal period and in the stress period. In the stress period, either real stress or sham stress was given in a randomized cross-over design. The stress scores, symptom severity, and pulse rates were measured. RESULTS: The stress scores and the severity of nausea were significantly greater under real stress, compared with sham stress. The percentages of weak, failed, rapid, premature, and hyper-contractile contractions were not significantly altered during real stress and during sham stress, compared with the basal period. The median resting pressure of the lower esophageal sphincter and distal contractile integral of esophageal contractions did not differ in the stress period, compared with the basal period. Contractile front velocity and distal latency of esophageal peristaltic contractions were significantly changed during real stress, which was not observed during sham stress. GER parameters were not significantly altered during real stress and during sham stress. CONCLUSION: Although acute auditory and visual stress seems to affect esophageal body motility, it does not induce significant motor abnormalities or increase GER in healthy humans.

Brucellosis is a well known systemic, zoonotic disease that can affect many organs. We report a rare case of spondylodiscitis with an epidural abscess caused by brucellosis. The patient was treated surgically for severe pain and concomitant devastating neurological deficit. A diagnosis of spondylodiscitis or an epidural abscess due to brucellosis must be considered when acute back pain, radiating pain and febrile episodes occur, particularly in people in a high risk group.

OBJECTIVE: To evaluate the relationship of work departments, carotid IMT, and plaque formation as predictors of cardiovascular disease in white-collar and blue-collar workers. METHOD: A total of 201 workers from a metal agricultural equipment manufacturing plant near Daegu were administered questionnaires to obtain information on their general characteristics, their work-related factors. In addition, the workers were given a clinical examination, which included a carotid artery ultrasonography. In total, 193 (96.0%) of questionnaires were completed and analyzed for this study. Multiple regression analysis and multiple logistic regression analysis were performed on the data for analysis. RESULT: Blue-collar workers had thicker carotid artery IMT when compared to white-collar workers. After adjustment, the carotid IMT was affected by age, working department, hypertension, and diabetes; plaque formation was affected by age, hypertension, total cholesterol, and excessive drinking. CONCLUSION: This study suggests that carotid IMT is associated with working department. Therefore, we need to examine the effect that occupational health services has on cardiovascular disease, focusing on the characteristics of each department.

Traumatic anterior dislocation of the hip is rare. Bilateral traumatic anterior dislocation is an even rarer injury; indeed, only 5 cases have been reported in the English literature. We describe a case of a bilateral traumatic anterior dislocation of the hip and a concomitant unstable lumbar burst fracture following a mechanism of injury distinctly different from other reports.

Bilateral avulsion fractures of the tibial tubercles are extremely rare. There is no case report about this in Korean literature. We present simultaneous bilateral tibial tuberosity fractures in 14-year-old adolescent male fell on the ground during running. These fractures were managed by open reduction and screw fixation. We gained complete union and removed metal after 6 months. Functional results were excellent 6 month after surgical treatment.

This study was conducted to determine if humoral antibody response of foot-and-mouth disease (FMD) vaccine improved in 8-week-old growing pigs born to well-vaccinated sows pre-treated with 60 mg of poly-γ-glutamic acid (γ-PGA) three days before vaccination. Antibody against FMD virus serotype O was measured 0, 2, 4 and 6 weeks post-vaccination, using a PrioCHECK FMDV type O ELISA kit. The results showed that positive antibody reactions against FMDV serotype O antigen among a component of the vaccine significantly increased in response to pre-injection with γ-PGA.

PURPOSE: This study was performed to compare the results between PFNA (Proximal Femoral Nail Antirotation) and PFN (Proximal Femoral Nail) in the treatment of peritrochanteric fracture. MATERIALS AND METHODS: The patient group with PFNA (n=24, group I) was taken from operations between February, 2007, and March, 2008, whereas the PFN patient group (n=24, group II) were taken from January, 2005, to January, 2007. Both groups were carefully compared with regard to operation time, estimated blood loss, amount of transfusion, ICU care, amount of drainage, average duration of admission, intra- and postoperative complications, radiologic union, Tip Apex Distance (TAD), the change of neck shaft angle, the sliding length of lag screw, Jensen's functional score, and Paker and Palmer's mobility score. RESULTS: The results of our study showed statistical (P<0.05) advantages of PFNA over PFN where estimated blood loss, amount of drainage, rate of complication, neck and shaft angle, and sliding length were concerned. However, there was no statistical significance between the two groups regarding the other areas that were examined (p>0.05). CONCLUSION: PFNA appears to be more effective than PFN for the treatment of peritrochanteric fractures of the proximal femur.
