Objective : The purpose of this study was obtaining data on the efficacy and safety of risperidone in child and adolescent psychiatric patients. Method : Thirty one children and adolescents (males n=18, females n=13, age ranged from 5.4 to 17.3 years) treated with risperidone were selected among child and adolescent psychiatric inpatients of Seoul National University Hospital from January, 2001 to June, 2002, and charts for them were reviewed retrospectively. Results : The primary psychiatric disorders treated with risperidone were schizophrenia and other psychosis, bipolar I disorder with psychotic features, Tourette's disorder, autism spectrum disorders, mixed receptive and expressive language disorder, attention deficit-hyperactivity disorder, conduct disorder and obsessive-compulsive disorder. twelve of these had comorbid mental retardation. Primary target symptoms of risperidone were psychotic symptoms (n=13 or $41.9\%$), behavioral symptoms (n=10 or $32.3\%$) including aggression, impulsivity, hyperactivity, stereotypy nonresponsive to other psychiatric treatments, and chronic and severe tics (n=8, $25.8\%$). The efficacy of risperidone was measured by clinical global improvement (CGI) for target symptoms, $67.7\%$ of subjects showed moderate or marked improvements and its therapeutic effect appeared to be maintained during at least 7.5 months. Mean daily dosage of risperidone was $0.05{\pm}0.01mg/kg$, the group with psychotic symptoms had significantly higher mean daily dosage (0.07mg/kg) compared with other two groups (0.04mg/kg) with behavioral symptoms or tics. A variety of adverse events were reported in this study : weight gain (n=23) most commonly reported, extrapyramidal symptoms (n=15), autonomic symptoms (n=6), sedation (n=5) and symptoms related to hyperprolactinemia (n=2) etc. Although there was no drug change related to the adverse events of risperidone, and $90\%$ of subjects at their last visits were maintained on it, thus its tolerability appeared good. Conclusions Results suggest that risperidone may be relatively safe and effective drug in managing a wide variety of child and adolescent psychopathologies such as psychotic symptoms, behavioral symptoms including aggression, impulsivity, hyperactivity and stereotypy nonresponsive to other psychiatric treatments, and chronic and severe tics. Controlled and long-term studies of efficacy and safety of risperidone treatment for children and adolescents are recommended in the future.

Probably the three most important components to a comprehensive evaluation of patients with attention-deficit hyperactivity disorder (ADHD) are the clinical interview, the medical examination, and the completion and scoring or behavior rating scales. Teachers and other school personnel are often the first to recognize that a child or adolescent might have ADHD, and often play an important role in the help-seeking/referral process. A diagnostic evaluation for ADHD should include questions about ADHD symptoms, other problems including alcohol and drug use, family history of ADHD, prior evaluation and treatment for ADHD. Screening interview or rating scales as well as interviews should be used. When it is feasible, clinicians may wish to supplement these components of the evaluation with objective assessments of the ADHD symptoms, such as psychological tests. These tests are not essential to reaching a diagnosis, however, or to treatment planning, but they may yield further information about the presence and severity of cognitive impairments that could be associated with some cases of ADHD. Screening for intellectual ability and academic achievement skills is also important in determining the presence of comorbid developmental delay or loaming disabilities. The number and type of symptoms required for a diagnosis of ADHD vary depending on the specific subtype. To receive a diagnosis of ADHD, the person must be experiencing significant distress or impairment in daily functioning, and must not meet criteria for other mental disorders which might better account for the observed symptoms such as mental retardation, autism or other pervasive developmental disorders, mood disorders, anxiety disorders. This report aims to suggest a practice guideline of assessment and diagnosis for children and adolescents with ADHD in Korea.

Attention-deficit hyperactivity disorder (ADHD) is a highly prevalent, impairing, and comorbid disorder that persists into adulthood. ADHD should be diagnosed in the same manner as other common adult mental health disorders. The three most important components in the comprehensive evaluation of patients with ADHD are the clinical interview, medical examination, and completion and scoring of behavior rating scales. The diagnostic evaluation of ADHD should include questions about the symptoms, family history, prior evaluation and treatment of ADHD, as well as other problems including alcohol and drug use. Screening interviews or rating scales, as well as interviews, should be used. When it is feasible, clinicians may wish to supplement these components of the evaluation with the objective assessments of the ADHD symptoms, such as through psychological tests. These tests are not essential to reaching a diagnosis, however, or to treatment planning, but may yield further information about the presence and severity of cognitive impairments that could be associated with some cases of ADHD. As comorbidity is the rule rather than the exception, clinicians should carefully screen for comorbid disorders as part of a comprehensive assessment of ADHD. To receive a diagnosis of ADHD, the person must be experiencing significant distress or impairment in his or her daily functioning, and must not meet the criteria for other mental disorders which might better account for the observed symptoms, such as mental retardation, autism or other pervasive developmental disorders, mood disorders and anxiety disorders. This report aims to suggest practice guidelines for the assessment and diagnosis of children, adolescents and adults with ADHD in Korea.
Purpose : To assess the usefulness of magnetic resonance imaging (MRI), karyotyping, brainstem auditory evoked potential (BAEP), electroencephalogram (EEG), tandem mass screening test, and newborn metabolic screening test in children with language delay for diagnosing underlying diseases. Methods : From January 2000 to June 2007, a retrospective chart review was performed for 122 children with language delay who visited the Child Neurology Clinic at Yeungnam University Hospital and who underwent neuropsychologic tests and other diagnostic evaluations for underlying diseases. They were grouped into phenomenological diagnostic categories, and test results were analyzed according to the underlying diseases. Results : Of 122 patients, 47 (38.5%) had mental retardation, 40 (32.8%) had developmental language disorders, 23 (18.9 %) had borderline IQ, and 12 (9.8%) had autism spectrum disorder. In 26 (21.3%) cases, the causes or relevant clinical findings to explain language delay were found. Eight (10.4%) of 77 MRIs, 6 (8.0%) of 75 EEGs, and 4 (5%) of 80 BAEPs showed abnormal results. Results directly attributed to diagnosing underlying diseases were 2 hearing defects in BAEPs and 1 bilateral perisylvian cortical dysplasia in MRIs. No abnormal results were found in karyotyping, tandem mass screening tests, and new-born screening tests. Conclusion : Commonly used tests to diagnose the cause of language delay are not very effective and should only be used selectively, according to patient characteristics. However, despite the low diagnostic yields from these tests, because many patients show abnormal results, these tests are useful when conducted in complete evaluation.

This study reported a case study that showed educational usefulness of SAFMEDS (Say All Fast a Minute Every Day Shuffled) on the improvement of Fluency. The participants were 3 experts with special teacher and speech and pathology, who enrolled a graduate level course, Research in Children with Autism Spectrum Disorder. The SAFMEDS strategy was employed as a study tool for the participants to acquire fluent verbal repertoires related to the key terminologies of Skinner's (1957) analysis of verbal behavior, list 60 pairs of terms. The participants developed 60 term flash cards which presented a target term on the front of the card, and its definition on the back. During the intervention, the participants were required to see the definition and says its term. The results of this study indicated that the SAFMEDS was effective to improve participants' fluent verbal repertoires in terms of both accuracy and fluency. The results of this study would be able to contribute for education professionals to improve certain target operant's accuracy and fluency.

The purpose of this study was to investigate the possibility of providing familiar tasks as a treatment option to decrease echolalia. Two comparisons were made:One was to compare ‘conversation condition’ and ‘task performance condition.’ and the other was to compare ‘task performance alone condition’ and ‘task performance along with contingency of reinforcement condition.’ Two echolalic children aged 12 and 13 years participated in the experiment and A-B-A-B-BC-B-BC design was used, in which A was conversation only, B was task performance, and C was task performance along with contingency of reinforcement. In the A condition, the therapist asked easy and short questions to the child;in the B condition the child was given familiar tasks with short instruction, and in BC condition, each child was reinforced for his performance on given tasks, in which immediate echolalia was controlled through his hands being held down for 5 seconds. Delayed echolalia was recorded without any intervention being given. Each child was put into each of the 7 treatment conditions. With a 15 minutes session, each child went through 5 to 6 sessions per day for 2 weeks. The mean echolalia(immediate) rates across the 7 treatment conditions were:For child 1, A(99%)-B(65%)-A(95%)-B(10%)-BC(7%)-B(6%)- BC(7%) and for child 2, A(67%)-B(62%)-A(63%)-B(35%)-BC(8%)-B(4%)-BC(0%). As to the generalization of the treatment effect of immediate echolalia to the untreated delayed echolalia, there was shown a drastic reduction of delayed echolalia in child 2:A(35%)-B(57%)-A(56%)-B(40%)-BC(8%)-B(5%)-BC(9%). Child l’s delayed echolalia was negligible(mean=3%) pre-and post treatments. In conclusion, the results of this study clearly show that providing a task performance setting with familiar tasks can certainly be helpful for minimizing echolalic response, and along with the use of the contingency of reinforcement technique it can further not only correct echolalic behavior to a negligible degree but also help the echolalic child generalize its treatment effect to the child’ overall language improvement.

Risperidone is a widely prescribed atypical antipsychotic agent. Approved by the FDA as the first drug to treat irritability associated with autism in children, it is also used to treat tic disorder and Tourette's syndrome. Its adverse reactions related to dentistry include dry mouth, the mechanism of which is yet to be identified. The aim of this study is to identify, at the cellular level, how and to what extent risperidone affects intracellular free calcium concentration ($[Ca^{2+}]_i$), an primary intracellular factor in the regulation of fluid secretion in salivary gland cells. The human salivary gland cell line (HSG) was grown in MEM supplemented with 10% BCS. In order to measure $[Ca^{2+}]_i$, Fura-2/AM was loaded in the HSG, and fluorescence at 340 nm/380 nm excitation was measured in the 500 nm emission ratio. After every experiment, a calibration experiment was conducted in order to readjust the ratio to the actual $[Ca^{2+}]_i$. Changes in $[Ca^{2+}]_i$ were measured in the presence of carbachol, ATP and histamine. The researcher then explored how the pretreatment of risperidone affected such changes. Findings of this study include: 1. In HSG, $[Ca^{2+}]_i$ increased due to the addition of carbachol, ATP and histamine. The presence of risperidone inhibited the action of histamine on this process, while making little effect on that of carbachol and ATP. 2. A quantification of $[Ca^{2+}]_i$ in relation to histamine of different concentrations indicates that the effect of histamine was concentration dependent with an $EC_{50}$ of $3.3{\pm}0.5\;{\mu}M$. 3. The inhibitory effect of risperidone on histamine-induced $[Ca^{2+}]_i$ was concentration-dependent with an $IC_{50}$ of $104.4{\pm}14\;nM$. 4. Risperidone inhibits histamine-induced Ca2+ release from endoplasmic reticulum and influx of extracellular $Ca^{2+}$ in HSG cells(p<0.05).

Objectives:This study was conducted to compare the clinical and neuropsychological characteristics by DSM-IV subtypes of attention deficit hyperactivity disorder(ADHD) patients who did not have comorbid psychiatric disorders. Methods:5-15 year old children with ADHD were recruited at psychiatric outpatient clinic of Yeungnam University hospital and the patients with comorbidity or neurological abnormalities were excluded. Finally, total 404 children with ADHD were selected for this study. There were 234 subjects of ADHD-C(57.9%), 156 subjects of ADHD-I(38.6%) and 14 subjects of ADHD-HI(3.5%), who fulfilled the DSM-IV diagnostic criteria. The mean age of the total subjects was 9.63±2.49 years old. The psychopathology, IQ, behavioral problems, neuropsychological executive function were evaluated before pharmacological treatment. The measures were Korean Personality Inventory of Child(K-PIC) for psychopathology, 4 behavioral check lists(ADDES-HV, ACTeRS, CAP, SNAP) for behavioral symptoms of ADHD, K-ABC and KEDI-WISC for IQ and Conner's CPT, WCST, SST for neuropsychological executive functions. Results:1) The prevalence of subtypes was ADHD-C, ADHD-I, ADHD-HI in decreasing order. There was no sex difference of prevalence among three subtypes. The mean age of ADHD-I was older than other subtypes. 2) There was significant differences of psychopathology among subtypes, the ADHD-C and ADHD-HI had higher than the ADHD-I in the scores of delinquent, hyperactivity and psychosis;the ADHD-C had higher than the ADHD-I in the scores of family relation and autism, the scores of ego resilience were lower than the ADHD-I. However, there was no difference in anxiety, depression and somatization scores among them. 3) The results of behavioral symptom check lists, the ADHD-C had higher the score of inattention, hyperactivity and impulsivity than the ADHD-I. Meanwhile the results of ACTeRs, which rated by the teachers, were different. 4) There were significant differences of sequential processing scale and arithmetics among subtypes in IQ using K-ABC, but there was no significant difference between the ADHD-C and the ADHD-I after excluding the ADHD-HI due to small numbers. 5) There was numerical difference among subtypes but did not reach statistical significance in three neuropsychological executive function tests. Conclusion:In conclusion, our results revealed that there was significant difference in clinical features among three subtypes but, no significant difference in executive functions.
