Inguinal and Scrotal Diseases in Children and Adolescents

In children and adolescents, inguinal and scrotal diseases are relatively common, and imaging is very useful for the diagnosis and differential diagnosis of these diseases. Therefore, it is important to understand the imaging findings of these diseases. In this article, we classify these diseases into small testes, cryptorchidism, patent processus vaginalis, acute scrotum pain, trauma, testicular tumors, and others and describe their characteristic findings.

Analysis of the Disposal Rate of Fresh Frozen Femoral Head in the Bone Bank of a Single Hospital / 대한정형외과학회잡지

Purpose@#This study analyzed the increase in disposal rate of femoral heads in the bone bank of a single hospital from medical disease and drug history, as assessed by the Korean health insurance review and assessment service. @*Materials and Methods@#The disposal rate and cause of 340 femoral heads were analyzed according to the regulations of the bone bank based on the standard model of the Ministry of food and drug safety. @*Results@#One hundred and seven (33%) of 323 femoral heads collected from 2009 to 2018, and 65 (46%) of 142 femoral heads collected from 2015 to 2018 were discarded. The most common causes were related to the history of dementia and the administration of radioisotope for nuclear medicine. @*Conclusion@#The current methods and screening tools can lead to errors in disposing of the available tissues in a bone bank. Thus, improved standards and screening methods are needed.

Effects and Development of an Experience-based Sex Education Program for Adjustment to Puberty in Upper Elementary Students

PURPOSE: The purpose of this study was to develop an experience-based sex education program to improve adjustment to puberty in elementary school students in the upper grades and to verify its effectiveness. METHODS: This study had a pretest-posttest nonequivalent control group design. The subjects of this study were a total of 95 sixth-graders in Y city (experimental group: 48, control group: 47). The measurement variables were sexual knowledge, body image, self-esteem, and satisfaction with life. Four sessions of the experience-based sex education program to improve adjustment to puberty, consisting of 40 minutes per session, were provided to the experimental group. RESULTS: Children's sexual knowledge, self-esteem, and satisfaction with life in the experimental group, which participated in the experience-based sexual education program to improve adjustment to puberty, showed a significant increase compared to the control group. However, there was no statistically significant difference in body image. CONCLUSION: This study presents the development of an experience-based sex education program for adjustment to puberty to overcome the shortcomings of existing sex education programs that are limited to sexual knowledge and attitudes, and also verified that the sexual knowledge, self-esteem, and life satisfaction of the elementary school students who were provided with the program improved meaningfully.

Effect of Early Menarche on Sexual Experience among Korean High School Girls

PURPOSE: The purpose of this study was to identify the influence of early menarche on sexual experience among high school girls in South Korea. METHODS: The study sample was comprised of 16,286 high school girls. Using statistics from the 11th (2015) Korea Youth Risk Behavior Web-based Survey, hierarchical logistic regression analysis was conducted. RESULTS: Among the girls, 5.8% reported early menarche. Early menarche was associated with sexual experience (Odds Ratio (OR), 5.27; 95% Confidence Interval (CI), 4.11–6.77). Controlled for sociodemographic, emotional and health behavior characteristics, early menarche was associated with sexual experience (OR, 3.98; 95% CI, 3.04–5.21). CONCLUSION: The results indicate that early menarche predicts an increase in sexual experience among female adolescents. Therefore, health education programs and health policy for interventions to improve sexual health are required for girls who are expected to experience early menarche.

Factors Affecting Contraceptive Use among Adolescent Girls in South Korea

PURPOSE: This study was done to identify contraceptive practices in adolescent girls in South Korea and predictors of contraceptive practices. METHODS: The study sample included 743 girls who had experienced sexual activity. Using statistics from the 12th (2016) Korea Youth Risk Behavior Web-based Survey, hierarchical logistic regression analysis was conducted. RESULTS: The contraceptive practice rate for adolescent girls was 34%. Contraceptive practice was associated with ‘age at first intercourse’ and ‘sexual intercourse after drinking’. For adolescent girls who had early sexual initiation and drank alcohol before sexual intercourse there was a tendency to reduce the practice of contraception. CONCLUSION: It is necessary to provide practical sex education to improve the practice of contraception in these adolescents. In addition, adolescent girls should be encourage to delay their first intercourse. The results of this study can also be used to develop education interventions regarding healthy sexuality behaviour including the practice of contraception.

Mental Health and Health Risk Behaviors of Multicultural Adolescents according to Their Mothers' Native Country: Using Data from the 11th (2015) Korea Youth Risk Behavior Web-Based Survey 2015

PURPOSE: The purpose of this study was to analyze the mental health and health risk behaviors of multicultural adolescents according to their mothers' native country. METHODS: For this study raw data from the 11th Youth Health Behavior Online Survey (2015) was examined. Mental health and health risk behaviors for 62,985 adolescents were analyzed according to their mothers' native country. Collected data were analyzed with the SPSS program using descriptive statistics and logistic regression analysis, to which the complex sample design was applied. RESULTS: The odds ratio of depression in multicultural adolescents compared to Korean adolescents was 44.92 (CI: 5.77-349.59) for adolescents whose mothers came from Cambodia and 3.00 (CI: 1.57-5.76) for adolescents whose mothers came from North Korea. The odds ratio of attempted suicide was 14.73 (CI: 3.09-70.22) for adolescents whose mothers came from Cambodia and 8.63 (CI: 3.45-21.62) for adolescents whose mothers came from North Korea. The odds ratio of problematic drinking in multicultural adolescents was 7.47 (CI: 1.71-32.67) for adolescents whose mothers came from Mongolia. CONCLUSION: Findings indicate that when planning a health promotion program for adolescents from multicultural families, a customized approach should be sought taking into account the characteristics of mothers' native country.

Operative Treatment of Pediatric Distal Forearm Bothbone Fracture

PURPOSE: Pediatric patients with distal forearm bothbone fractures of surgical indication were treated with the Kapandji reduction technique for radius and flexible intramedullary nail for ulna at our institution. The purpose of this study is to evaluate clinical and radiological results. MATERIALS AND METHODS: From February 2012 to June 2014, we retrospectively evaluated 16 out of 18 cases with distal forearm bothbone fractures treated with the Kapandji reduction technique for radius and flexible intramedullary nail for ulna with at least 1-year follow-up. The average age at operation was 9.1 years (7-13 years). RESULTS: Adequate reduction for both radius and ulna was achieved for all cases, and none of the cases showed re-displacement until the last follow-up. Mean 6.6 weeks lapsed until bony union was observed for the radius. For the ulna, the mean was 6.5 weeks. All patients gained full wrist range of motion at the last visit. CONCLUSION: For pediatric distal forearm bothbone fractures, intrafocal Kapandji reduction and internal fixation with Kirschner wire for radius and reduction and internal fixation with a flexible intramedullary nail for ulna is the technique for handy reduction. Use of this technique can prevent re-displacement during the union process and achieve excellent clinical and radiologic results.

A Case of Asymptomatic Giant Right Atrial Aneurysm

A healthy 8 year old boy was referred to our hospital because of cardiomegaly on the chest X ray. No cardiac murmur was detected on chest examination and normal sinus rhythm was checked by electrocardiogram. The 2-D echocardiogram showed a huge dilated right atrium and a normal tricuspid valve and right ventricle. The findings of cardiac angiogram and MRI was compatible with the isolated giant right atrial aneurysm. For the prevention of atrial arrhythmia and thromboembolism, he underwent successful surgical reduction of the right atrium and cryoablation and the follow-up X ray showed no cardiomegaly.
