BACKGROUND: This study aimed to evaluate the clinical and radiological outcomes of arthroscopic bioabsorbable screw fixation in osteochondritis dissecans (OCD) in adolescent patients with unstable lesions causing pain. METHODS: The study included 11 patients (10 males and 1 female) with OCD who underwent arthroscopic bioabsorbable screw fixation between July 2007 and February 2014 and were available for follow-up for more than 12 months. The mean age at diagnosis was 16.3 years (range, 11 to 19 years), and the average follow-up period was 51 months (range, 12 to 91 months). Clinical results were evaluated using the Knee Injury and Osteoarthritis Outcome Score (KOOS), Lysholm knee score, and International Knee Documentation Committee (IKDC) score measured before surgery and at follow-up. Functional evaluation was made using the Tegner activity scale. Magnetic resonance imaging (MRI) and second-look arthroscopy were performed at the 12-month follow-up. RESULTS: Between the preoperative assessment and follow-up, improvements were seen in the KOOS (range, 44.9 to 88.1), Lysholm knee score (range, 32.6 to 82.8), and IKDC score (range, 40.8 to 85.6). The Tegner activity scale also improved from 2.8 to 6.1. Based on postoperative MRI, there were eight Dipaola grade I cases and three grade II cases. No complications due to fixation failure developed in any case. Second-look arthroscopy at 12 months postoperatively revealed that the lesion was covered with cartilage in all cases. CONCLUSIONS: For unstable OCD lesions causing pain in adolescents, arthroscopic bioabsorbable screw fixation provided favorable outcomes with reduced pain and restoration of movement. Therefore, it should be considered as an effective treatment for OCD.

This article provides an overview of the developmental history and rationale of medical ethics to establish the code of ethics and professional conduct of the Korean Academy of Child and Adolescent Psychiatry (KACAP). Most medical professional organizations have their own codes of ethics and conduct because they have continuous responsibility to regulate professional activities and conducts for their members. The Ethics and Award Committee of the KACAP appointed a Task-Force to establish the code of ethics and conduct in 2012. Because bioethics has become global, the Ethics Task Force examined global standards. Global standards in medical ethics and professional conduct adopted by the World Medical Association and the World Psychiatric Association have provided the basic framework for our KACAP's code of ethics and professional conduct. The Code of Ethics of the Americal Academy of Child and Adolescent Psychiatry has provided us additional specific clarifications required for child and adolescent patients. The code of ethics and professional conduct of the KACAP will be helpful to us in ethical clinical practice and will ensure our competence in recognizing ethical violations.

PURPOSE: The purpose of this study is to provide information on the actual status and prevailing trend of prophylaxis for venous thromboembolism (VTE) following total knee arthroplasty (TKA) in South Korea. MATERIALS AND METHODS: The Korean Knee Society (KKS) developed a questionnaire with 6 clinical questions on VTE. The questionnaire was distributed to all members of KKS by both postal and online mail. Participants were asked to supply details on their specialty and to select methods of prophylaxis they employ. Of the total members of KKS, 27.9% participated in the survey. RESULTS: The percentage of surgeons who routinely performed prophylaxis for VTE was 60.4%; 19.4% performed prophylaxis depending on the patient's health condition; and the remaining 20.2% never implemented prophylaxis after surgery. The common prophylactic methods among the responders were compression stocking (72.9%), pneumatic leg compression (63.3%), perioral direct factor Xa inhibitor (46.9%), and low-molecular-weight heparin (39.5%). For the respondents who did not perform prophylaxis, the main reason (51.5%) was the low risk of postoperative VTE considering the low incidences in Asians. CONCLUSIONS: The present study involving members of the KKS will help to comprehend the actual status of VTE prevention in South Korea. The results of this study may be useful to design VTE guidelines appropriate for Koreans in the future.

BACKGROUND: Meniscus tears are commonly associated with anterior cruciate ligament (ACL) ruptures. It is essential to repair meniscal tears as much as possible to prevent early osteoarthritis and to gain additional stability in the knee joint. We evaluated the results of arthroscopic all-inside repair using the Meniscal Viper Repair System (Arthrex) on meniscus tears simultaneously with ACL reconstruction. METHODS: Nineteen out of 22 patients who were treated with arthroscopic all-inside repair using the Meniscal Viper Repair System for meniscus tear associated with ACL rupture were evaluated. ACL reconstructions were performed at the same period. The mean follow-up period was 16.5 months (range, 12 to 24 months). The clinical results of the meniscus repair were evaluated by symptoms (such as catching or locking), tenderness, effusion, range of motion limitation, and the McMurray test. Clinical success was defined by negative results in all five categories. The Hospital for Special Surgery (HSS) score was evaluated. Objective results were evaluated with secondary look arthroscopy or magnetic resonance imaging (MRI). The MRI results were categorized as completely repaired, incompletely repaired, and failure by Henning's classification. The results of second-look arthroscopy were evaluated with the criteria of meniscal healing. RESULTS: The clinical success rate was 95.4% and the HSS scores were 93.9 +/- 5.4 at the final follow-up. According to Henning's classification, 15 out of 18 cases showed complete healing (83.3%) and two cases (11.1%) showed incomplete healing. Seventeen out of 18 cases that underwent second-look arthroscopy showed complete healing (94.4%) according to the criteria of meniscal healing. Only one case showed failure and the failure was due to a re-rupture at the sutured area. Complications of ACL reconstruction or meniscus repair were not present. CONCLUSIONS: The results demonstrate that arthroscopic all-inside repair using the Meniscal Viper Repair System is an effective treatment method when it is performed simultaneously with ACL reconstruction.

OBJECTIVE: People with attention-deficit/hyperactivity disorder (ADHD) exhibit considerable impairment in social, academic, or occupational functioning. The present study aimed to examine the patterns of associations between ADHD symptoms, depression, and family functioning. METHODS: The sample consisted of 1,022 adults randomly selected from a district in Seoul, South Korea. Several self-assessment scales were utilized to rate ADHD symptoms (both past and current), current symptoms of depression, and level of family functioning. ADHD symptoms in the children of these participants were also assessed. Pearson's correlation and multiple linear regression analyses were performed; structural equation modeling (SEM) was conducted to determine the best fitting model. RESULTS: Adult ADHD symptoms were positively associated with depressive symptoms. Depressive symptoms, in turn, mediated the relationship between adult ADHD symptoms and cohesion among family members. In addition, depressive symptoms mediated the relationship between adult ADHD symptoms and their children's ADHD symptoms. CONCLUSION: The relationship between adult ADHD symptoms and family dysfunction may be influenced by depressive symptoms. When treating ADHD in adults, clinicians should pay attention to the presence or absence of depression.

OBJECTIVES: It is known that adolescents with autism spectrum disorder (ASD) often concurrently exhibit attention-deficit hyperactivity disorder (ADHD). The objective of this study is to investigate how ADHD symptoms modify clinical characteristics in adolescents with ASD. METHODS: Subjects were recruited from the Program for the Education Enrichment of Relational Skills program, which is a program for adolescents with ASD to promote and train social skills. The study participants and their parents completed the study questionnaires, such as the ADHD rating scale, Autism Diagnostic Observation Schedule, and Korean version of Child Behavior Checklist. RESULTS: Adolescents with ASD and ADHD (N=19) were found to have more impaired sociality, less open communication with their parents, and more behavioral and emotional problems compared with adolescents with ASD, and without ADHD (N=28). CONCLUSION: Although further research is needed, the results of our study suggest that adolescents with ASD present different clinical characteristics when comorbid with ADHD.

OBJECTIVE: There are no published prevalence estimates of elimination disorders and their association with disruptive-behavior disorders among children in the Asian region using standardized diagnostic interviews. This study was conducted to determine the prevalence of elimination disorders and its association with disruptive-behavior disorders in a representative sample of children in Seoul, Korea. METHODS: The diagnosis of enuresis and encopresis was derived from parent-reported data for "enuresis and encopresis," collected using the Diagnostic Interview Schedule for Children, from a representative sample of 6- to 12-year-old children (n=1,645) who participated in the 2005 Seoul Child and Adolescent Mental Health Survey. Prevalence data for attention deficit and disruptive-behavior disorders were collected from the same sample. RESULTS: The overall 12-month prevalence of nocturnal enuresis and encopresis was 1.8% and 0.6%, respectively. Enuresis and encopresis prevalence in boys was significantly greater than that in girls. Enuresis and encopresis was most common at 7 to 9 years of age. Enuresis was significantly associated with ADHD (OR 2.6, 95% CI 1.0-6.9) and conduct disorder (CD; OR 4.7, 95% CI 1.0-22.4). CONCLUSION: Enuresis is significantly associated with ADHD and CD, so these conditions must be assessed together during the evaluation of children with enuresis.

OBJECTIVES: Dysregulation of the central noradrenergic system may be involved in the pathophysiology of attention-deficit hyperactivity disorder (ADHD). The aim of this study was to examine the differences in pre- and post-treatment cerebral perfusion according to the MspI polymorphisms of the alpha-2A-adrenergic receptor gene (ADRA2A) in children with ADHD. METHODS: Thirty seven drug-naive ADHD children (8.9+1.8 years old, M=32, F=5) were genotyped. Baseline single-photon emission computed tomography (SPECT) and clinical assessments were performed for ADHD children. After treatment with methylphenidate for eight weeks, SPECT and clinical assessment were repeated. RESULTS: No differences in baseline clinical assessments or cerebral perfusion were observed according to the MspI genotype. However, after treatment, ADHD children with the G/G genotype at the MspI polymorphism showed hyperperfusion in the right cerebellar declive (p=.001, uncorrected) and hypoperfusion in the left lentiform nucleus and left cingulate gyrus (p<.001 and p=.001, uncorrected), compared to children without the G/G genotype. CONCLUSION: Although the results of this study should be interpreted cautiously, they suggest a possible role of the MspI polymorphisms of the ADRA2A gene in methylphenidate-induced changes in cerebral perfusion.

PURPOSE: This study was conducted for evaluation of clinical uses of anterior cruciate ligament (ACL) reconstruction with an Achilles allograft using the remnant technique by comparison and analysis stability, functional assessment and results of second-look arthroscopy between the remnant technique and the non-remnanat technique. MATERIALS AND METHODS: A total of 48 patients who underwent ACL reconstruction using an Achilles allograft were selected and divided into two groups depending on the presence of remnant. The preserving group included 26 patients and non-preserving group included 22 patients. The two groups were compared and analyzed with regarding to stability (Stress view Lachman test, pivot shift test), functional assessment (International Knee Documentation Committee, Lysholm score, Tegner score, single hoop test, shuttle turn, carioca test), and the result of second-look arthroscopy (study design: prosepective cohort study). RESULTS: In the final result, the remnant group showed significant improvement in the Tegner and carioca tests compared with the non-remnant group (p<0.05). In second-look arthroscopy, the remnant group showed better coverage of synovium (p<0.05). CONCLUSION: ACL reconstruction with an Achilles allograft using the remnant technique showed better results in functional assessment and finding in second-look arthroscopy compared with the non-remnant technique group.

For most orthopedists, total knee arthroplasty (TKA) has been regarded as the most effective surgery for patients with severe knee diseases. Though seldom occur, postoperative infection certainly remains one of the most devastating and dreaded complications of TKA. Thus, careful and early diagnosis is needed. After diagnosis, categorize the infection type and choose a rightful and sequential step of treatment are recommended.
