Depression is a mental symptoms that accompany psychological symptoms such as anxiety, gloom, a sense of failure, helplessness as well as a physical symptoms that shows in the adaption process of stress. Depression may result in cognitive, emotional, and behavioral disorders in accordance with individual experience. In particular, the depression when growing lowers the concentration on studies of children and adolescents and also increases the violence and interpersonal problems causes a serious loss to individuals and society. This study analyzed the longitudinal data using mixed models to investigate how depression affects girls who experienced violence in home or at school.

The autistic disorder is identified as an independent clinical entity, since the first description of Leo Kanner. The etiologies of the autistic disorder are almost unclear and the autistic disorder has several abnormalities in aspect of morphology and function of brain. Self-mutilation is observed in the low functioning autistic patients, and early treatment for self mutilation are needed in order not to be chronic. This article reviewed the drugs for the several symptoms of the autistic disorder, especially for self-mutilation. The serotonin reuptake inhibitors does not have clear primary anti-aggressive effects. The dopamine blockers have considerable effects in order to decrease aggression and self injury, and the risperidone is most recommended because of side effects of conventional drugs. The naltrextone does not have consistent study results yet. The clonidine has aggression-decreasing effect. Also lithium is effective on the treatment for aggressive and self-injurious behaviors. And the anticonvulsants including carbamazepine are effective on aggressive explosive behaviors. In the future the pharmacotherapy for self-mutilation will be advanced through stalbe diagnosis and measurement of treatment response.

The aim of this study is to examine the diagnostic profiles and related clinical variables of children with attention and hyperactivity in psychiatric outpatient clinic. Seventy one children with age range of 5 to 14 were diagnosed by DSM-IV, and assessment battery including KEDI-WISC, KPI-C, ADS(ADHD Diagnostic System) were completed. The subjects were divided into 3 diagnostic groups：ADHD only(n=17), ADHD comorbid(n=27), Other diagnosis(n=27). The results were as follows：In ADHD comorbid group, tic disorder, developmental language disorder, borderline intellectual function, oppositional defiant/conduct disorder, and learning disorder were combined in descending order. Other diagnosis group consisted of tic disorder, borderline intellectual function, depression/anxiety, oppositional defiant/conduct disorder, and others. There were significant differences in IQ, PIQ, and VIQ among the three groups, and ADHD only group showed higher scores of IQ and VIQ than ADHD comorbid group. On the KPI-C, there were no significant differences in all subscales among the three groups. On the visual ADS, omission error and sensitivity showed significant differences among the three groups, and ADHD comorbid group represented higher omission error and lower sensitivity than other diagnostic group. The findings indicated that the inattention and hyperactivity symptoms could be diagnosed into diverse psychiatric disorders in child psychiatry, and ADHD children with comorbidity will show more problems in academic performance and school adjustment.

The history of pediatric psychopharmacology is very short and the research on safety, efficacy and side effects is preliminary and long-term effect on growth and maturation is not well known yet. Clinical findings have shown that the responses to antidepressants, antipsychotics, CNS stimulants and steroids in children and adolescents might be different from adult populations. Based on these findings, this paper reviewed three issues, Firstly, in developmental pharmacokinetics. the author discussed the developmental factors affecting drug absorption, distribution, protein-binding, metabolism and excretion. Secondly, in developmental pharmacodynamics, developmental characteristics of dopamine, serotonin, norepinephrine receptors and their clinical implications were reviewed. Lastly, in pharamcogenetic part, the clinical utility of pharmacogenetics, pharmacokinetic aspects of pharmacogenetics, the pharmacodynamic aspects of pharmacogenetics, the association studies of dopamine-related alleles in neuropsychiatric disorders such as attention-deficit hyperactivity disorders or Tourette’s disorders, pharmacogenetic studies dopamine-related alleles and the pharmacogenetic studies of serotonin-related alleles. Based on these preliminary research, future pharmacogenetic applications in childhood and adolescent psychiatry were also discussed.

Menkes disease is an X-linked recessive copper transport disorder characterized by neurological deterioration, connective-tissue damage, and abnormal hair growth. It is caused by the mutation of the ATP7A gene. This report describes a four-month-old boy with neurological symptoms typical of Menkes disease plus unusual liver involvement. He developed seizures at three months of age and exhibited hypotonia, cephalhematoma, a sagging face, redundant and hypopigmented skin, and abnormal hair growth. In addition, he had unexplained hepatomegaly and high hepatic transaminase. We confirmed the diagnosis of Menkes disease by mutation analysis of the ATP7A gene. To exclude other possible causes for the hepatic abnormalities, a liver biopsy was performed, revealing intracytoplasmic cholestasis, focal spotty necrosis, and minimal lobular activity. The patient's liver involvement may be an underestimated complication of Menkes disease.

Objectives：Conduct disorder is one of the most frequent diagnosis in outpatient and inpatient mental health facilities for children and adolescents. This study investigated the clinical characteristics of children and adolescents with conduct disorder. Methods：The study employed a retrospective review of 45 inpatients diagnosed with conduct disorder by DSM-IV criteria at SNUH Child Psychiatric Unit from 1993, March to 1998, September. Results：The results were as follows：1) The sex ratio was 2：1, male dominant. Mean age on admission was $12.8{\pm}2.4$ years old(male：$12.2{\pm}2.3$, female：$14.1{\pm}2.1$). The mean age of male subjects was significantly lower than that of female subjects(p<.05). 2) We classified all subjects according to child- or adolescent-onset type by DSM-Ⅳ. Childhoodonset type was 42.2%, and adolescent-onset, 57.8%. The onset of male subjects were significantly earlier than that of female subjects(p<.05). 3) The most common complaint was 'serious violation of rules'(77.8%) by DSM-Ⅳ dimensions, while the most common single symtom was 'run away from home overnight at least twice while living in parental or parental surrogate home'(48.9%). 4) The comorbid psychopathology of the subjects were frequently described as follows, in order of frequency：substance use(42.2%), ADHD(35.6%), depression(20.0%), tic disorder(11.1%), bipolar disorder(4.4%). 5) On MMPI, both Pd and Ma subscales got the highest scores. The mean of total IQ by KEDIWISC was $100.0{\pm}15.1$. Female subjects' IQ was higher than that of male subjects. 6) Regarding the number of visits to the OPD after discharge, many subjects(33.3%) had visited OPD fewer than four times. Conclusions：In this study, the male to female ratio of adolescent type showed a decreasing trend. An interesting finding was the fact that socio-economic circumstances, as well as the level of education among patients, were higher than those of previous studies. The subjects' problem were also principally self contered and posed no threat to others.

Purpose : Early identification of developmental disabilities allows intervention at the earliest possible point to improve the developmental potential. The Ages and Stages Questionnaire (ASQ), a parent- completed questionnaire, can be used as a substitute for formal screening tests. The purpose of this study was to evaluate the validity of the Korean version of the ASQ (K-ASQ) as a screening tool for detecting developmental delay of young Korean children in the setting of a busy pediatric outpatient clinic. Methods : Parents completed the K-ASQ in the waiting room of the pediatric outpatient clinic of St. Mary's Hospital, Catholic University Medical College. Out of 150 completed the ASQ, 67 who were born term and had no previous diagnosis of developmental delay, congenital anomalies, or neurological abnormalities were enrolled. The cut-off values of less than 2 standard deviations (SD) below the mean for the ASQ were used to define a "fail", and children who failed in one or more domains tested were classified as "screen-positive". Diagnosis of developmental delay was made when the developmental indices fell below -1 SD of the Bayley Scales of Infant Development-II. Results : (1) The mean age of children was $16.4{\pm}7.4$ months. Ten children (14.9%) were small-for- gestational age infants. The mean birth weight and gestational age were $3.1{\pm}0.6kg$ and $38.8{\pm}1.4$ weeks. Nine children (13.4%) were twins and 33 (49.0%) were male. The mean maternal education in years was $13.6{\pm}2.4$, and 31.3% had full-time jobs. The time for completing the ASQ was $10.2{\pm}3.0$ minutes. (2) Seventeen children (25.4%) were classified as screen-positive, four of them were delayed in development. Among eight children diagnosed with developmental delay, four were screen-positive and the other four were screen-negative by the ASQ. (3) The test characteristics of the ASQ were as follows: sensitivity (50.0%); specificity (78.0%); positive predictive value (23.5%); negative predictive value (92.0%). Conclusion : The high negative predictive value of the K-ASQ supports its use as a screening tool for developmental delay in the setting of a pediatric outpatient clinic.

Self-injurious behavior is often showed in mental retardation, especially in autism. Self-injurious behavior has been regarded as a symptom cluster rather than a disease but it is an emergent clinical situation that can directly affect mortality. This case is about a refractory autistic patient who showed a self-injurious behavior of hitting the head repetitively. He was hospitalized and was treated by pharmacotherapy and behavior therapy and for this reason this clinical experience is reported with literature review. The patient is a 7-year old boy who was ward admitted from 1999 April 20 till July 10 into OO hospital OO ward because of self-injurious behavior. During the 12 weeks he had admission treatment. As for the pharmacotherapy, haloperidol was dosed up from 0.5mg to 1.0mg from the 4th week and combination drug therapy was done during the admission with naltrexone 25-50mg. As for the behavioral therapy, Differential Reinforcement of Other behavior was used and regular play therapy was done. To remove the physical restraint, headgear and hard sleeve was used. Currently, OPD follow up treatment is being done and haloperidol 0.5mg and naltrexone 50mg is maintained. The patient’s mother is educated and play therapy is done an hour daily at home. When the patient was released form the hospital, self-injurious behavior was decreased more than the moderate state and remission state is still being maintained at the outpatient clinic.

This study was conducted to investigate the communicative intent between Reactive Attachment Disorder(RAD) and Developmental Language Disorder(DLD). The subject of this study were 20 27-51 monthold children(10 RAD Children, 10 DLD children) functioning at similar stage of language development. The communicative intent was investigated vertical and horizontal dimension. Rating of vertical communicative intent was based on the assessment scales devised by Wetherby and Prutting(1984). Horizontal dimension was measured by the assessment guidelines of Wetherby and Prizant(1989). All the data were rated by two rators independantly. 1) In communicative intent, vertical development level of DLD children was more sophiscated than that of RAD children. 2) DLD children expressed more horizontal communicative intent than RAD children. The percentage of the three major categories(behavioral regulation, social interaction, and joint attention) of communicative intent in DLD children was lined up social interaction>joint attention>behavioral regulation. On the contrary, RAD children displayed in order of behavioral regulation>social interaction>joint attention. In addition, DLD children showed diversely as compared with RAD children.
