ABSTRACT
Objective@#This study aimed to identify the factors affecting posttraumatic stress disorder (PTSD) symptom remission prospectively through a 1-year follow-up of sexual assault (SA) victims. @*Methods@#A total 65 female SA victims who visited the crisis intervention center were included. Self-administered questionnaires regarding PTSD symptoms and PTSD related prognostic factors were conducted at both recruitment (T1) and 1 year after recruitment (T2). The multivariate analyses were used to determine the significant predictors of PTSD remissionon-remission state 1 year after SA. @*Results@#In logistic regression analysis, both anxiety and secondary victimization were identified as significant factors explaining the results on PTSD remissionon-remission state at T2 (Beck’s Anxiety Inventory [BAI], p=0.003; Secondary Victimization Questionnaire, p=0.024). In a linear mixed analysis, both depression and anxiety were found to be significant variables leading to changes in Posttraumatic Diagnostic Scale for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition from T1 to T2 (BAI, p<0.001; Center for Epidemiological Studies Depression Scale, p<0.001). @*Conclusion@#Depression, anxiety symptoms, and secondary victimization after SA were associated with PTSD symptom non-remission 1 year after SA.
ABSTRACT
Objectives@#This study aimed to investigate the correlation between the Comprehensive Attention Test, Korean-Wechsler Intelligence Scale for Children-Fourth Edition, and Attention-Deficit/Hyperactivity Disorder (ADHD) Rating Scale-IV scores in children and adolescents with ADHD. @*Methods@#Fifty-five children and adolescents diagnosed with ADHD and not taking psychiatric medications were included in this retrospective study. A correlation analysis was performed. @*Results@#Although simple visual and auditory selective attention have diagnostic value in traditional continuous performance tests, this study revealed that inhibition-sustained attention and interference-selective attention are also effective in evaluating ADHD. Furthermore, the correlation between the attention and intelligence test scores varied depending on the use of visual or auditory stimuli. @*Conclusion@#The findings of this study contribute to clarifying our understanding of the cognitive characteristics of children and adolescents with ADHD and can be used in future research.
ABSTRACT
Background@#The purpose of this study was to identify the prevalence of posttraumatic embitterment disorder (PTED) among soldiers, and examine its relation to stress, depression, self-esteem, impulsiveness, and suicidal ideation. @*Methods@#The subjects of this study were 200 soldiers and 197 control subjects, a total of 397 persons. Measurement tools used included the PTED self-rating scale, Stress Response Inventory, Beck Depression Inventory, Rosenberg Self-Esteem Inventory, Barratt Impulsiveness Scale, and Beck Scale of Suicide Ideation.Result: The major findings of the analysis are as follows: first, 11.5% of the soldiers were in the risk group for PTED, and 4% of them had PTED. Second, PTED in the soldiers was significantly associated with a number of variables such as their educational background, stress, depression, self-esteem, impulsiveness, and suicidal ideation, while it was not significantly associated with age. Third, through the hierarchical multiple regression analysis, it was found that academic background, stress, and depression had a statistically significant positive effect on the incidence of PTED in the soldiers. @*Conclusion@#In order to prevent and effectively intervene in PTED in soldiers, there is a need for interventional efforts focused on depression and stress related to negative life events.
ABSTRACT
Stimulants, such as amphetamine and methylphenidate, are one of the most effective treatment modalities for attention deficit hyperactivity disorder (ADHD) and may cause various movement disorders. This review discusses various movement disorders related to stimulant use in the treatment of ADHD. We reviewed the current knowledge on various movement disorders that may be related to the therapeutic use of stimulants in patients with ADHD. Recent findings suggest that the use of stimulants and the onset/aggravation of tics are more likely to be coincidental. In rare cases, stimulants may cause stereotypies, chorea, and dyskinesia, in addition to tics. Some epidemiological studies have suggested that stimulants used for the treatment of ADHD may cause Parkinson’s disease (PD) after adulthood. However, there is still a lack of evidence that the use of stimulants in patients with ADHD may cause PD, and related studies are only in the early stages. As stimulants are one of the most commonly used medications in children and adolescents, close observations and studies are necessary to assess the effects of stimulants on various movement disorders, including tic disorders and Parkinson’s disease.
ABSTRACT
Objectives@#Tic disorder is a neurodevelopmental disorder characterized by multiple involuntary movements of muscles or vocalization. Although tic symptoms subside as the patient ages, some patients suffer from significant functional impairments related to severe tic symptoms. This manuscript aimed to review the latest scientific evidences for the effect of cognitive-behavioral interventions on tic disorder. @*Methods@#The relevant studies were identified by searching medical research databases. We focused our search on studies published between 2000 and 2020 in order to reflect the latest scientific evidence. A total of 821 articles were identified in the initial database search and 27 articles were finally included for the review after the exclusion of duplicated and irrelevant articles. @*Results@#Behavioral therapies including habit reversal training, Comprehensive Behavioral Intervention for Tics, and exposure and response prevention were the most widely studied interventions for tic disorder and are recommended as first-line treatments for tic disorders with high confidence. Cognitive psychophysiologic approaches were also reported to be effective. @*Conclusion@#Further studies are needed to support the future treatment of tics with low-cost and more widely available treatments, in order to ensure better treatment outcomes.

ABSTRACT
Objective@#This study aimed to develop a brief self-report measure of depressive and anxiety symptoms in victims of sexual violence. @*Methods@#The sample, which consisted of 215 victims and 255 healthy controls, was recruited between December 2016 and November 2018 from eight Sunflower Centers. Eligible items were selected from existing scales of depression (CES-DC and CES-D) and anxiety (SAI-C and BAI) symptoms by item-total correlation coefficients and item response theory (IRT) analysis. Internal consistency coefficients were computed and the receiver operating characteristics curve was inspected to assess the validity of the brief scale and determine optimal cutoff scores. @*Results@#The brief scales showed high internal consistency across all age groups. The optimal cutoff score of brief depression scale was 1.5 for children, 2.5 for adolescents, and 2.5 for the adults. That of brief anxiety scale was 8.5, 6.5, and 3.5, respectively. @*Conclusion@#The results underscore the need for age-appropriate screening measures of depressive and anxiety symptoms in victims of sexual violence.
ABSTRACT
Objectives@#This study aimed to evaluate the reliability and validity of the Korean Form of the Premonitory Urge for Tics Scale (K-PUTS). @*Methods@#Thirty-eight patients with Tourette’s disorder who visited Jeonbuk National University Hospital were assessed with the K-PUTS. Together with the PUTS, the Yale Global Tic Severity Scale (YGTSS), the Children’s Yale-Brown Obsessive Compulsive Scale (CY-BOCS), the attention-deficit/hyperactivity disorder (ADHD) rating scale (ARS), and the Adult ADHD Self-Report Scale (ASRS) were implemented to evaluate concurrent and discriminant validity. @*Results@#The internal consistency of items on the PUTS was high, with a Cronbach’s α of 0.79. The test-retest reliability of the PUTS, which was administered at 2 weeks to 2 months intervals, showed high reliability with a Pearson correlation coefficient of 0.60. There was a significant positive correlation between the overall PUTS score and the YGTSS score, showing concurrent validity. There was no correlation between the PUTS, CY-BOCS, and ASRS scores, demonstrating the discriminant validity of the PUTS. Factor analysis for construct validity revealed three factors: “presumed functional relationship between the tic and the urge to tic,” “the quality of the premonitory urge,” and “just right phenomena.” @*Conclusion@#The results of this study indicate that the K-PUTS is a reliable and valid scale for rating premonitory urge of tics.
ABSTRACT
PURPOSE: The aim of this retrospective study is to describe changes of gastric mucosa in patients with adjustable gastric band migration, and to evaluate the diagnostic value of these changes.MATERIALS AND METHODS: The postoperative endoscopies of all patients that underwent adjustable gastric band surgery at a single tertiary center were retrospectively reviewed. Gastric mucosal patterns were classified based on the appearance of gastric mucosae compressed by adjustable gastric bands, as follows; Group A: normal appearance, Group B: snakeskin (reticular) appearance without band migration, Group C: snakeskin appearance with band migration, and Group D: recuperated gastric mucosa with advanced band migration.RESULTS: Postoperative endoscopic findings of 109 patients obtained from Jan 2012 to Oct 2018 were available, and these patients were assigned to the four groups, as follows; 82 to group A, 5 to group B, 14 to group C, and 8 to group D. Times (months) between AGB implantation and initial postoperative endoscopy evaluations were 45.2±22.3, 40.0±28.2, 36.2±18.6, and 42.1±17.0, respectively (P=0.531). Of the five patients in Group B, 3 underwent band explantation due to band migration (P=0.000).CONCLUSION: Conclusion A snakeskin pattern of gastric mucosa compressed by adjustable gastric band is strongly associated with adjustable band migration. The presence of this pattern might predict band migration before endoscopic confirmation and its identification might prevent complications associated with long-standing band migration.

Along with the field of adult psychiatry, antipsychotic agents are increasingly used in the field of child and adolescent psychiatry. Although neuroleptic malignant syndrome (NMS) and rhabdomyolysis are rare complication associated with antipsychotic agent, clinicians should need to pay attention to all potential adverse drug reaction (ADR). Also, ADRs in child and adolescent could show different signs and symptoms compared with those in adult. In this case report, we present a case of NMS in a child which occurred shortly after the resolution of rhabdomyolysis which was induced by low-dose risperidone.

Most patients with Tourette's disorder experience an uncomfortable sensory phenomenon called the premonitory urge immediately before experiencing tics. It has been suggested that premonitory urges are associated with comorbidities such as obsessive compulsive disorder, anxiety disorders, and attention-deficit/hyperactivity disorder, although these associations have been inconsistent. Most patients experience tics as a result of the premonitory urges, and after the tics occur, most patients report that the premonitory urges are temporarily relieved. As a consequence, several studies have assessed the premonitory urge and its potential therapeutic utility. Based on the concept that the premonitory urge induces tics, behavioral treatments such as Exposure and Response Prevention and Habit Reversal Therapy have been developed. However, it is still unclear whether habituation, the main mechanism of these therapies, is directly related to their effectiveness. Moreover, the observed effects of pharmacological treatments on premonitory urges have been inconsistent.

Sphingosine-1-phosphate (S1P) plays an important role in trafficking leukocytes and developing immune disorders including autoimmunity. In the synovium of rheumatoid arthritis (RA) patients, increased expression of S1P was reported, and the interaction between S1P and S1P receptor 1 (S1P1) has been suggested to regulate the expression of inflammatory genes and the proliferation of synovial cells. In this study, we investigated the level of S1P1 mRNA expression in the blood leukocytes of RA patients. In contrast to the previous reports, the expression level of this gene was not correlated to their clinical scores, disease durations and ages. However, S1P1 was transcribed at a significantly lower level in the circulating leukocytes of RA patients when compared to age-, and sex-matched healthy controls. Since these data may suggest the participation of S1P1, further studies are needed to determine the role of this receptor in the pathogenesis of RA.

In this study, we evaluated the association between autism spectrum disorders (ASDs) and 10 single-nucleotide polymorphisms (SNPs) in the 5' region of the semaphorin 5A gene (SEMA5A) for 250 Korean trios including children with ASDs. Family-based association testing and haplotype analysis revealed a statistically significant association between rs194085 and multiple sociality traits with Korean ASDs in the dominant model (p < 0.001, corrected p=0.035). This indicates that genetic variations in the 5' region of SEMA5A play a role in the genetic predisposition to sociality traits in Korean ASDs.

Carbon nanotubes (CNTs) are nanomaterials that have been employed in generating diverse materials. We previously reported that CNTs induce cell death in macrophages, possibly via asbestosis. Therefore, we generated CNT-attached polyvinylidene fluoride (PVDF), which is an established polymer in membrane technology, and then examined whether CNT-attached PVDF is immunologically safe for medical purposes compared to CNT alone. To test this, we treated RAW 264.7 murine macrophages (RAW cells) with CNT-attached PVDF and analyzed the production of nitric oxide (NO), a potent proinflammatory mediator, in these cells. RAW cells treated with CNT-attached PVDF showed reduced NO production in response to lipopolysaccharide. However, the same treatment also decreased the cell number suggesting that this treatment can alter the homeostasis of RAW cells. Although cell cycle of RAW cells was increased by PVDF treatment with or without CNTs, apoptosis was enhanced in these cells. Taken together, these results indicate that PVDF with or without CNTs modulates inflammatory responses possibly due to activation-induced cell death in macrophages.

OBJECTIVES: The study compared the intelligence test profiles of Tourette's Disorder (TD), attention-deficit hyperactivity disorder (ADHD), and TD with ADHD (TD+ADHD) groups. METHODS: The Korean Wechsler Intelligence Scale for Children-third edition (K-WISC-III) and Korean Wechsler Intelligence Scale for Children-fourth edition (K-WISC-IV) were administered to 13 children and adolescents with TD, 17 children and adolescents with ADHD, and 15 children and adolescents with TD+ADHD. Each parameter was compared among the groups using the Kruskal-Wallis test. RESULTS: The mean scores of the freedom from distractibility/working memory index (FD/WMI) and the digit span and arithmetic subtests of the TD+ADHD group were significantly lower than those of the TD group. CONCLUSION: According to the intelligence test results, the comorbid ADHD+TD group showed a significant decrease in working memory compared to the TD group. These findings are similar to those of previous research on cognitive functions and suggest that the TD+ADHD comorbid and TD alone groups exhibit different endophenotypes. The results also imply that WISC-III and WISC-IV, the most commonly used intelligence tests clinically, are effective in evaluating cognitive functions such as attention. Further research is required to confirm these results.

Motor disorders in childhood include tic disorder, developmental coordination disorder, and stereotypic movement disorder. A tic is a sudden, rapid, repetitive and nonrhythmic movement (motor tics) or phonic production (phonic or vocal tics) that can occur at any part of the body. Developmental coordination disorder (DCD) is characterized by marked impairment in the acquisition and performance of motor skills. Stereotypic movement disorder is a common childhood disorder which repetitive, hard to control, aimless motor activity interrupts everyday life or causes self-infliction of a child. Despite increased attention and the growing scientific knowledge about motor disorders, there are limitations in our understanding and knowledge about the pathogenesis and the management of the disorders. Motor disorders can itself be the primary diagnosis, or can be secondarily diagnosed caused by other disorders, and accompany many neuropsychiatric disorders such as autism and attention deficit hyperactivity disorder (ADHD), which in turn impairs proper learning and socializing of the children with motor disorders. Therefore comprehensive medical history taking, continuous observation of the changes in symptoms, and systematic assessment considering the child's developmental stage and current adaptive capacity are needed. Behavioral therapy and pharmacological therapy are the two most often mentioned treatments of motor disorders.

We assessed empathy in medical residents, including factors modifying empathy and the relationship between empathy and burnout. Participants (n = 317 residents, response rate = 42%) from 4 university hospitals completed a socio-demographic questionnaire, the Jefferson Scale of Empathy (Health Professional version, Korean edition), and the Maslach Burnout Inventory (MBI). Participants were classified by medical specialty: “people-oriented specialty” (POS group) or “technology-oriented specialty” (TOS group), with more women in the POS than in the TOS group, χ2 = 14.12, P < 0.001. Being female, married, and having children were factors related to higher empathy (gender, t = -2.129, P = 0.034; marriage, t = -2.078, P = 0.038; children, t = 2.86, P = 0.005). Within specialty group, POS residents showed higher empathy scores in the fourth as compared to the first year, F = 3.166, P = 0.026. Comparing POS and TOS groups by year, fourth year POS residents had significantly higher scores than did fourth year TOS residents, t = 3.349, P = 0.002. There were negative correlations between empathy scores and 2 MBI subscales, emotional exhaustion (EE) and depersonalization (DP). Additionally, first year POS residents had higher DP scores than did first year TOS residents, t = 2.183, P = 0.031. We suggest that factors important for empathy are type of medical specialty, marriage, siblings, and children. Burnout state may be related to decreasing empathy.

OBJECTIVES: Brain-derived neurotrophic factor (BDNF), a neurotrophin involved in neurogenesis and synaptic plasticity, has been implicated in the pathophysiology of several neuropsychiatric disorders. However, there have been no consistent findings regarding BDNF levels in panic disorder. In this study, we investigated plasma BDNF levels in panic disorder, and evaluated whether there is an association between plasma BDNF levels and severity of symptoms of panic disorder. METHODS: Plasma BDNF levels were measured in 110 panic disorder patients and 110 normal control subjects using the enzyme-linked immunosorbent assay. The severity of symptoms of panic disorder was determined using the Panic Disorder Severity Scale, Acute Panic Inventory, Agoraphobic Cognition Questionnaire, and Hamilton Anxiety Rating Scale. RESULTS: The mean plasma BDNF levels of patients with panic disorder were significantly lower compared with those of control subjects (192.50 pg/mL vs. 693.75 pg/mL). No significant association was observed between plasma BDNF levels and the severity of symptoms of panic disorder. CONCLUSION: These results suggest that BDNF may play a potential role in the pathophysiology of panic disorder.

OBJECTIVES: Repetitive and stereotyped behaviors are core symptoms in children with autism spectrum disorders (ASD). The purpose of our study was to investigate the frequency of motor stereotypes in ASD children and their clinical features. METHODS: Among 171 ASD children (age range, 3-15), the ASD group with motor stereotypes was defined according to two items in the Korean version of Autism Diagnostic Interview-Revised (K-ADI-R). We compared the clinical features, behavior problems and severity of other domains in the K-ADI-R and executive functions between the ASD group with motor stereotypes and the ASD group without motor stereotypes. RESULTS: Ninety (52.6%) of 171 ASD children had motor stereotypes. The ASD group with motor stereotypes had a lower intelligence quotient score (62.23 vs. 84.94, p<.001) compared to the ASD group without motor stereotypes. The ASD group with motor stereotypes had more impairments in the social interaction domain [adjusted odds ratio (AOR) 1.11, p=.001] and communication domain (AOR 1.15, p=.008). Thought problems and lethargy were more frequent in the ASD group with motor stereotypes than the ASD group without motor stereotypes (AOR 2.059, p=.034 ; adjusted OR 1.045, p=.046). However, no significant differences in executive function were observed between the ASD group with motor stereotypes and the ASD group without motor stereotypes. CONCLUSION: The ASD group with motor stereotypes showed more impairment in social interaction and communication domains, which are core symptoms of autism. Motor stereotypes may indicate greater severity of ASD.

OBJECTIVES: The purposes of this study were to examine the reliability and validity of the Korean version of Social Communication Questionnaire (K-SCQ) and to determine cut-off scores for diagnosis of autism spectrum disorder (ASD). METHODS: A total of 166 subjects with ASD and their 186 unaffected siblings were recruited through child psychiatry clinics of university hospitals. Board certified child psychiatrists screened all probands suspected to have ASD based on the Diagnostic and Statistical Manual of Mental Disorders, fourth edition. To confirm the diagnoses, the Korean versions of the Autism Diagnostic Observation Schedule and the Autism Diagnostic Interview-Revised (K-ADI-R) were administered to all the subjects. All parents completed the K-SCQ and Social Responsiveness Scale (SRS). The non-ASD siblings were evaluated with the same instruments as the probands with ASD. We performed a factor analysis to examine the structure of K-SCQ. For testing the validity of K-SCQ, we compared the difference in Lifetime and Current scores of probands with ASD and their non-ASD siblings using t-test and analysis of covariance. Correlations between the K-SCQ and other measurements of ASD symptomatology, including K-ADI-R totals and domain scores and SRS, were examined. Receiver operation characteristic curve analysis was performed to extract cutoff scores discriminating affection status. RESULTS: Four factors were extracted through factor analysis of K-SCQ ; 1) social relation and play, 2) stereotyped behavior, 3) social behavior, and 4) abnormal language. Cronbach's internal consistency was .95 in K-SCQ Lifetime, and .93 in K-SCQ Current. There were significant differences in total score of K-SCQ, both in Lifetime and Current between the ASD group and non-ASD siblings group (p<.001). K-SCQ scores were significantly correlated with K-ADI-R subdomain scores and SRS total scores (p<.001). The best-estimate cut-off scores of K-SCQ for diagnosis of ASD were 12 for 48 months and over, and 10 for below 47 months. CONCLUSION: Our findings suggest that the K-SCQ is a reliable and valid instrument for screening autistic symptoms in the Korean population. Lower cut-off scores than the original English version might be considered when using it as a screening instrument of ASD.
