In femorsl neck fracture, viability of the femoral head depends on the revascularization of the femoral head. The purpose of this study is to observe the effect of early fixation and anatomical reduction by measuring the Tc-99m-MDP uptake ratio of the femoral head in experimental animsls. Femoral neck region of 20 mature rabbits were osteotomized completely and divided into 2 groups ; each group consisted of 10 rsbbits. Group 1 had two Kirschner wire fixation after osteotomy and anatomic reduction. Group 2 had no fixation after osteotomy. The uptake ratio of Tc-99m-MDP of the femoral head in each group were measured st the intervals of 24 hours, 48 hours, 1 week, 2 weeks, 3 weeks, and 4 weeks, respectively. The results obtained were as follows ; 1. In experimental group 1, the mean uptake ratio of the femoral head was 0.72±0.13 at 1 day after operation, increased to a level of 1.44±0.14 at 1 week, increased to a maximal value of 2. 90±0.36 at 3 weeks and decreased to a level of 1.10+0.12 at 4 weeks. 2. In experimental group 2, the mean uptake ratio of the femoral head was 0.70±0.10 at 1 day, 0.64±0.13 at 1 week, decreased to a maximal value of 0.33±0.05 at 3 weeks and 0.47±0.05 at 4 weeks, showing decreased level below 1.0. The results suggest that early anatomicsl reduction and rigid fixation of femoral neck fracture is helpful for revascularization of the femoral head and prevention of non union.

Malignant osteoblastoma is very rare tumor which shows histological findings of an aggressive pattern and benign clinico-radiological features, and also called as aggressive or pseudomalignant osteoblstoma. The authors experienced one csse of malignant osteoblastoma involving diaphysis of left humerus in 22-year old man. The patient is healthy and maintains his normal activity without recurrence over five years after complete excision of cystic mass, curettage and bone graft.

A complete fracture dislocation at the cervicothoracic junction is rare and accompanied by severe spinal cord injury. This region is difficult to image with plain radiography, and to immobilize with external orthosis due to the biomechanical forces exerted in this transitional portion of the spinal column. We experienced a rare case in 52-year-old male victim of a car accident. He sustained paraplegia, and complained of dyspnea and neck pain of 10 days duration at another hospital. The delayed clinical rediagnosis was a C6 and 7 spinous process fracture and a cervicothoracic fracture dislocation, with complete transection of spinal cord, which was based on a clinical examination, simple radiography, CT and MRI. Skeletal traction was immediately applied, followed by a posterior pedicle screw to stabilize the spine and secure the grafts. Rehabilitation was initiated and the dysphagia and dyspnea, due to aspiration pneumonia, were improved, but no neurologic recovery was made after the 1st postoperative year.

Pneumomediastinum is a relatively uncommon, infrequently reported entity, In the evaluation of these entity, it is important to exclude pathological causes, including Boerhaave's syndrome which carries a high mortality. Spontaneous pneumomediastinum is related to excessive intraalveolar pressure leading to rupture of perivascular alveoli in the setting of a Valsalva maneuver without communication to gut material. So, it has a benign self-limited course and rarely requires medical intervention. On the contrary, secondary pneumomediastinum caused by instrumental, traumatic, and spontaneous perforation of esophagus. Although the prognosis have been improved since the advent of broad-spectrum antibiotics and nutritional support, pneumomediastinum due to esophageal perforation still has a high morbidity and mortality. The most important prognostic factor is the time interval between perforation and initiation of therapy, and an awareness and a high clinical suspicion is critical in the early diagnosis and treatment. Recently, we have experienced 2 cases of pneumomediastinum, one case was spontaneous pneumomediastinum and the other may be caused by instrumental esophageal perforation. We report the clinical course of the patients with a current literature review.

OBJECTIVES: With the increase in cancer prevalence, the health behavior of cancer survivors has become an important issue. This study was conducted to examine the psychosocial correlates of behavior changes after cancer diagnosis. METHODS: 95 patients completed questionnaires assessing depression, anxiety, insomnia, posttraumatic stress symptoms, social constraints, personal beliefs about cancer cause and health-related behavior changes after cancer diagnosis. RESULTS: In the multiple logistic regression analysis, insomnia was the only significant predictor of positive change in physical behavior : normal sleep group(Odds ratio=9.462, 95% CI 1.738-51.509) and subthreshold insomnia group(Odds ratio=10.529, 95% CI 1.701-65.161) showed a larger increase compared to the insomnia group. In psychosocial behavior, low age, religion and causal belief in hormonal factors were independent factors that predicted increase in positive change. CONCLUSIONS: This study showed a difference between predictors of physical and psychosocial health behavior change after breast cancer diagnosis. Multi-faceted approaches are required to promote positive change in health behavior in cancer patients.

8.Parents' perception about child's height and psychopathology in community children with relatively short stature.
Annals of Pediatric Endocrinology & Metabolism 2015;20(2):79-85
PURPOSE: This study investigated the relationship between height and psychopathology in community children with relatively short stature according to the parents' reports. Also, the matter of parental concern about child's height was explored. METHODS: The child behavior checklist (CBCL), the Brief Encounter Psychosocial Instrument (BEPSI), and the child-health questionnaire-parent form 50 (CHQ-PF50) were administered to 423 parents (from elementary and middle school children's) in Gangnam, South Korea. Subjects were divided into three groups; (1) relatively short (n=30), (2) average stature (n=131), (3) relatively tall (n=153). CBCL, BEPSI, and CHQ-PF50 scores were compared among three groups. RESULTS: There were no significant differences in psychosocial burden associated with relatively short stature measured by Korean version of the BEPSI and Korean version of the CBCL scores among three groups. But general health perception score of relatively short was significantly lower than that of nonshort on the CHQ-PF50. Also, they were more used complementary medicines, milk and growth hormone compared to the nonshort. The parents' expected height of their children was 180.6+/-3.5 cm for boys and 166.7+/-3.5 cm for girls. This is respectively 90 percentile and 75-90 percentile for the Korean standard adult height. CONCLUSION: Our study shows that in Korea, Parents tended to regard relatively short children as having health problems. Also, the parental expectation for their child's attainable height is unrealistically tall, mostly due to lack of correct medical information.

9.Major Lessons from the MTA in Treatment of Attention-Deficit Hyperactivity Disorder.
Journal of the Korean Academy of Child and Adolescent Psychiatry 2010;21(1):3-10
OBJECTIVES: The current review aimed to describe the major findings of the NIMH Collaborative Multisite Multimodal Treatment Study of Children with Attention-Deficit Hyperactivity Disorder (MTA) with regard to the treatment of children with attention-deficit hyperactivity disorder (ADHD). METHODS: We performed a general review of the literature regarding the efficacy of the MTA's proposed treatments. RESULTS: There is a large and still increasing body of evidence regarding the MTA's treatment outcomes. We present and discuss details of the findings at each follow-up point. CONCLUSION: Currently, findings regarding the MTA's treatments suggest children with combined-type ADHD exhibit significant impairment in adolescence, despite their initial symptom improvement. Further studies, using innovative treatment approaches and targeting specific areas of adolescent impairment, are needed in order to enhance ADHD treatment outcomes.

PURPOSE: The aim for this study was to investigate clinical manifestation of seasonal influenza A and B during the 2012 winter season in Wonju, South Korea. Their clinical and laboratorial characteristics and effect of oseltamivir were compared and analyzed. METHODS: Children under the age of 18 years who visited the Wonju Severance Christian Hospital with fever or acute respiratory symptoms and who were diagnosed with influenza A or B by rapid antigen test from nasopharyngeal swab were selected for the study. The medical records of patients were retrospectively reviewed. RESULTS: Influenza A was detected in 374 patients (83.7%), and influenza B in 72 (16.6%). The incidence of influenza A was highest in February (n=186), while that of influenza B was highest in March (n=36). The most common symptoms were fever (n=434, 97.1%) and cough (n=362, 81.0%). No significant differences were observed between influenza A and B in symptoms and laboratory data. Patients who had used oseltamivir within 2 days showed statistically lower admission rate, shorter admission duration, and lower incidence of pneumonia. CONCLUSION: This study found no statistical difference between influenza A and B, in symptoms, progression, and laboratory test, but those who were treated with oseltamivir given within 2 days of the onset of fever experienced more positive outcomes.
