Supracondylar fracture of the humerus is the most common fracture of the elbow in children. Early accurate reduction is very important to obtain good results. Authors tried to reduce the fracture accurately under the concept of intact hinge mechanism. Forty-five displaced supracondylar fractures which were not able to be reduced by closed method were admitted for open reduction at our department from April 1981 to October 1985. They were analysed clinically. The result are as follows: 1. The patient age ranged from 3 to 14 years; 16.2% were between 7 and 8 years. 70.3% were boys Left humerus was affected in 70.3% of all cases. 2. The most common cause of fracture was falling down from height. 94.6% of fractures were extension type. The severity of displacement in 34 patients(90.2%) were grade III or 1V of Holmberg classification. 3. Only in 2 patients cubitus varus deformity was observed as residua and among the patients who were followed more than one year, only 2 had about 10 degrees of limitation of elbow motion. 4. In Holmberg's grade II, III, IV group, 22 cases(100.0%) of the both side pinned and 12 cases (80.0%) of one side pinned showed excellent or good results. Therefore, both side pinning could have contributed in obtaining more accurate reduction. 5. According to Mitchell and Adams' Criteria, 34 cases(91.9%) had satisfactory results.

PURPOSE:Differential diagnosis of sexual precocity has been aided by new imaging techniques and endocrine evaluation. Sexual precocity, defined as the appearance of secondary sexual characteristics before the age of 8 years in girls and 9 years in boys, was studied to evaluate the sex incidence and etiology of sexual precocity. METHODS:A total 95 children(87 girls and 8 boys) who were diagnosed with sexual precocity at St. Mary's Hospital, Catholic University Medical College from 1984 to 1996, were studied. All underwent standard anthropometric measures. They were assinged to diagnostic categories on the basis of clinical assessment, endocrine evaluation, radiologic imaging, and pelvic ultrasonography. RESULTS: 1) The most common cause of sexual precocity was premature thelarche, 50 cases(52.6%) of all children. 2) Central precocious puberty was noted in 7 girls and 3 boys(female to male ratio 2.3:1). The causes were not identified in 6 cases(85.7%) in girls, but the causes were not found in 1 cases(33.3%) in boys. The idiopathic central precocious puberty occurs at least two fold more frequently in girls than in boys. 3) Incomplete precocious puberty was noted in 29 girls and 5 boys(female to male ratio 5.8:1). In the causes of 29 girls with incomplete precocious puberty, congenital adrenal hyperplasia were found in 23 cases, autonomous functional ovarian cyst in 5 cases and McCune-Albright syndrome in 1 case. In the causes of 5 boys with incomplete precocious puberty, virilizing adrenal cortical tumor were found in 3 cases, congenital adrenal hyperplasia in 1 case, and hepatoblastoma in 1 case. CONCLUSION: Sexual precocity occurs at least ten fold more frequently in girls than in boys. Premature thelarche is the most common form of sexual precocity.

PURPOSE: This study investigated sexual knowledge, its related factors, and the needs of sex education among elementary, middle, and high school students in order to develop a sex education program. METHODS: The participants comprised 721 students in grades 5 through 12, from Seoul and the Kyeonggi-do area, in South Korea. Data was collected from the end of August through the end of September 2014, using an anonymous self-administered questionnaire. SPSS Statistics 21.0 was used for the descriptive analysis, chi-square, t-test, ANOVA, and multiple regressions. RESULTS: Higher-grade students had a higher level of sexual knowledge than lower-grade students, but the overall level of sexual knowledge was low. Multivariate analysis showed that gender, grade, school record, and experiences of sex education from family and school were significant predictors of sexual knowledge among adolescents. Coping skills related to sexual crisis situations was the most wanted content of sex education. CONCLUSION: The results of this study suggested that it is important to develop a sex education program that considers the needs of sex education among adolescents. Also, it is important to periodically perform a survey to identify the need of sex education among elementary, middle, and high school students.

4.Surgical results of stress incontinence treated by Trans-obturator tape (TOT): Clinical analysis of 80 cases.
Korean Journal of Obstetrics and Gynecology 2006;49(6):1326-1331
OBJECTIVE: This study was performed to evaluate the efficacy and safety of Trans-obturator tape (TOT) in the surgical treatment of stress incontinence and analyze the postoperative clinical outcome. METHODS: Between August 2004 and September 2005, females diagnosed as having stress incontinence (pure or mixed) were operated on using TOT. Eighty cases with more than three-month follow-up period were included for this study. RESULTS: Patient age ranged from 28 to 74 years (mean, 58). After surgical treatment using TOT, 74 cases (92.5%) of stress incontinence showed complete recovery, 4 cases (5%) showed partial recovery, and 2 cases (2.5%) were unchanged without further functional deterioration. Urgency in the mixed incontinence was improved in 30 in 36 cases (83.3%) and frequency was changed for the better in 20 of 27 cases (62.9%). The mean operation time was 14.3 minutes and the mean hospital stay was six hours. Postoperative evaluation with cystoscope was unnecessary. The postoperative complication rate was 10% (8/80). Postoperative wound bleeding occurred in one case and intraoperative bladder perforation happened in one case. Postoperative transient urgency was developed in one case and postoperative transient frequency developed in three cases. Two patients complained of weak urinary stream. CONCLUSION: The surgical treatment using TOT is thought to be a safe and efficient means for the outpatient management of stress incontinence. And also, this method appears to have an effect on urgency and frequency.

Dental practice can produce and spread some infetious diseases from patients to dentist, dental assistant, and dental labors. One possible method for preventing these cross-contamination is to immerse dental impression in chemical disinfectants. So far many investigators studied on the dimensional changes of dental impressions and on the surface qualities of stone casts made from impression following immersion in disinfectants. This study was proposed to evaluate some popular impression/disinfectant combination from the point of dimensional stability. Impression was taken from dental arch-shaped metal model. Irreversible hydrocolloid and 3 elastomers(polyvinyl siloxane, polysulfide, polyether) were immersed in 3 disinfectants (2% glutaraldehyde, 1% povidone-iodine, 0.5% sodium hypochlorite) for 10 minutes and measured both cross-arch and anterior-posterior distance under stereo microscope to evaluate dimensional change. The results obtained were as follows: 1. Dimensional changes of irreversible hydrocolloid impression was statistically different in crossarch and anterior-posterior distance when immersed in 2% glutaraldehyde solution and in anterior-posterior distance when immersed in 0.5% sodium hypochlorite solution from control group(p<0.05). 2. Dimensional changes of polyvinyl siloxane and polysulfide impression were not statistically different from control group (p>0.05). 3. Dimensional changes of polyether impression was statistically different in cross-arch distance when immersed in 0.5% sodium hypochlorite solution and in anterior-posterior distance when immersed in 1% povidone-iodine solution from control group (p<0.05). 4. In all cases, dimensional changes were less than 0.1% from the original dimension and concluded clinically acceptable

The problem of carbon monoxide intoxication has been increasing since 1950s and it is still regarded as one of the most serious public health problem in Korea. If the patients survives the acute episode, elimination of carbon monoxide occurs in the rate of a halt-time of 3 to 4 hours. Nevertheless, there may remain after effect. Therefore, the present study was desinged to elucidate the change of myocardial tissue caused by acute carbon monoxide poisoning were evaluated by electrton microscopic observation of the severity of the mitochondrial swelling and cytochrome oxidase activity, which was demonstrated by histochemical staining with diaminobenzidine(DAB). Male Sprague-Dawley rats were exposed to the carbon monoxide of 1500 ppm for 150 minutes. They were divided into two groups ; one group were treated with hyperbaric oxygenation 15 minutes after carbon monoxide exposure, the other were not treated. Rats were sacrified 6 hours, 12 hours, 1 day, 3 days, 7days, 14 days, and 21 days after carbon monoxide exposure. The specimens were collected from the apex of the heart. In the group without hyperbaric oxygenation, mitochondrial swelling subsided 21 days after carbon monoxide exposure accompained by restoration of cytochrome oxidase activity. On the other hand, with hyperbaric oxygenation, healing process was shortened. Cytochrome oxidase activity was restored 7 days after carbon monoxide exposure.

8.A Study on Serum Leptin Values by Elisa Method in Children
Korean Journal of Pediatric Gastroenterology and Nutrition 2000;3(2):175-180
PURPOSE: Leptin is an adipocyte-derived blood-borne satiety factor that acts on its cognate leptin receptor in the hypothalamus, thereby regulating food intake and energy expenditure. We measured the leptin concentrations in serum of normal and obese children with human leptin ELISA kit, unlike previous study with leptin RIA kit and investigated the relationship between leptin concentrations and body mass index, gender, and age. METHODS: We measured serum concentrations of leptin in 67 children who were visited to the Department of Pediatrics, Chungnam National University Hospital during the period of 5 months from February, 1999 to June, 1999. Height, weight, obesity index, and body mass index were measured in 67 subjects. Leptin values in serum were measured by sandwich ELISA method. Data analysis was done according to the obesity, body mass index, gender and age. RESULTS: The mean concentration of leptin was 7.69±8.83 ng/ml in normal children group and 36.34±18.57 ng/ml in obese group. Serum leptin concentrations were significant correlation with the body mass index (p < 0.01). Serum leptin concentration was significant higher in the group of over 10 years of age (p < 0.01). Leptin levels showed no significant difference by gender. CONCLUSION: Serum leptin levels were significantly higher in obesity group than in control one, and they were correlated with body mass index and age. Measurements of leptin value by sandwich ELISA method are very useful and easily applicable to determine obesity.

STUDY DESIGN: This is a retrospective study that focused on the perioperative complications when performing posterior arthrodesis for treating degenerative lumbar disorders in elderly patients. OBJECTIVES: We wanted to analyze the perioperative risk factors and the complications associated with posterior lumbar decompression and arthrodesis in patients who were sixty-five years of age or older. SUMMARY OF LITERATURE REVIEW: Lumbar arthrodesis is commonly done in elderly patients to treat degenerative spine problems. These patients may be at an increased risk for complications because of their age and their associated medical conditions. MATERIALS AND METHODS: We studied 111 patients who were over 65 years old and they were able to be followed up for more than 3 months after performing posterior arthrodesis during the recent 5 years. Sixty-one patients who had undergone posterolateral fusion (PLF) were classified as group A, and 50 patients who had undergone posterior lumbar interbody fusion (PLIF) using a PEEK cage were classified as group B. We analyzed their rates of complications and the causative factors, according to operative methods and age, and these complications occurred within 12 weeks after the operations. RESULTS: Complications occurred for 43 patients of group A, and for 26 patients of group B. The differences in the rates of complications were statistically significant, and group A had a more complications than did group B. The relations between medical problems and the incidence of perioperative complications were statistically significant for both groups. CONCLUSIONS: Elderly patients with medical problems should be made aware that they are at an increased risk for surgical complications, and attention hould be paid to controlling the blood loss and limiting the operative time. The PLIF using a PEEK cage was identified as a procedure that could reduce the perioperative complications.
