목적: 주의력결핍 과잉운동장애(ADHD)는 소아에서 3-5%의 유병률을 보이며 전두엽의 억제기전 저하와 대뇌의 카테콜라민 대사이상이 관련된다고 알려져 있다. ADHD 환아에서 야뇨증을 비롯한 다양한 하부요로계 증상을 동반한다는 보고가 있지만 국내에서는 ADHD 환아들에 대한 보고가 없기에 저자들은 ADHD 환아에서 배뇨증상을 알아보기 위해 본 연구를 시행하였다. 방법: 2009년 10월부터 2011년 3월까지 DSM-IV 진단기준에 근거하여 ADHD로 진단받은 33명의 환아들과 같은 기간 동안 신경계 질환이나 요로계 질환 없이 상기도 감염으로 외래를 내원한 환아 30명을 대상으로 배뇨와 배변에 대한 설문지를 시행하였다. 결과: ADHD 환자군의 평균 연령은 $9.09{\pm}2.8$세(남 28: 여 5) 이었고, 대조군의 평균 연령은 $8.58{\pm}3.1$ (남 20: 여 10) 이었다. ADHD 환아군에서 대조군에 비해 요절박(P=0.017), 절박 요실금(P=0.033), 변비(P=0.045)의 유병률이 대조군에 비해 유의하게 높았고, 복압배뇨, 간헐뇨, 배뇨지연 행동에는 두 군간에 유의한 차이가 없었다. 야뇨증은 ADHD 환아군에서 12.1% (4/33)로 대조군의 0%에 비해 많았지만 통계학적인 유의성은 없었다. 결론: ADHD 환아는 대조군에 비해 요절박, 절박 요실금과 변비의 유병률이 유의하게 높았다.

Objectives : The aim of this study is to investigate the effectiveness of treatment with osmotic-release oral system methylphenidate (OROS-MPH) on quality of life (QOL) in children with attention-deficit hyperactivity disorder (ADHD). Another aim is to assess the relationship between change in QOL and other factors including children's symptoms and academic performance or parents' depression and parenting stress. Methods : A total of 111 medication-naive children with ADHD in a multicenter, open-label, 12-week trial of OROS-MPH completed an evaluation using diverse rating scales at two time points; at baseline and after 12 weeks of treatment. Scales for investigation of children included the Parent Report Form-Children's Health and Illness Profile-Children's Edition (PRF-CHIP-CE) on QOL, the ADHD Rating Scale-IV on symptoms, and the Academic Performance Rating Scale (APRS). The Beck Depression Inventory and Parenting Stress Index were used for assessment of their parents. Results : Total scores for mean PRF-CHIP-CE increased from $207.9{\pm}26.7$ at baseline to $226.3{\pm}25.9$ after 12 weeks of treatment (p<.001). The change of APRS showed the strongest correlation with the increment of PRF-CHIP-CE scores (Pearson coefficient=0.561, p<.001), even after controlling for other factors (partial correlation coefficient=0.420, p<.001). Conclusion : Treatment with MPH-OROS results in improvement of QOL in children with ADHD in Korea. The advance in academic performance plays a key role in this change of QOL.

Objectives: To identify the factors affecting long-term adherence to methylphenidate treatment in children with attention-deficit hyperactivity disorder (ADHD). Methods: A retrospective medical record review of 239 ADHD patients (mean age $9.3{\pm}2.6$ years, range 6.0-17.4 years) who had visited the child and adolescent psychiatry clinic at a university hospital, in Seoul, Korea from March 2005 to February 2008. Subjects were diagnosed as ADHD based on the criteria set forth in the Diagnostic and Statistical Manual of Mental Disorders 4th edition, text revision version (DSM-IV-TR) and underwent neuropsychological tests including the continuous performance test (CPT). Treatment discontinuation was defined as the last prescription date when the medication possession rate (MPR) became less than 0.80. Subjects were divided into three groups and labeled as Group I, non-adherence without pharmacotherapy, Group II, non-adherence with short-term pharmacotherapy, and Group III, adherence with long-term pharmacotherapy. Results: Ninety (37.7%) patients were grouped as non-adherent (Groups I+II) and 149 (62.3%) as adherent (Group III). The adherence group exhibited lower intelligence, higher symptom severity, and a higher number of comorbid psychiatric disorders than controls. The use of stimulants was significantly associated with long-term adherence to treatment. Additionally, the duration of interval between the date of the first visit and the date of the first prescription was positively associated with long-term adherence. Conclusion: About two-thirds of patients diagnosed as ADHD adhered to the treatment six months after the first visit. With respect to patient evaluation and the development of treatment strategies, factors affecting early drop-out and longer follow-up must be considered.

Objectives : In this study, patients with tic disorders who visited an Oriental medicine clinic were examined for their demographic characteristics, characteristics of symptoms, relation to Attention-deficit Hyperactivity Disorder(ADHD) and peculiarity according to various variables such as motor and vocal tics. Methods : After surveying 292 patients who visited an Oriental medicine clinic with tic symptoms as main complaints for 17 months, SAS 9.1, a statistical program was used for statistical analysis. Results : 1. The BMI of male tic patients was significantly higher than female ones and it was similar to or higher than the normal group. 2. Patients who are eldest children were 1.7 times higher than those who are not eldest ones. 3. The most usual case of motor tics was the eye blink and the most one of vocal tics was a dry cough. 4. There was no significant difference between male and female patients for all symptoms of motor and vocal tics, but male patients had significantly more obsessions related to tics than female ones. 5. There was no significant difference in the age of initial occurrence of Transient tic disorder(TTD), Chronic tic disoder(CTD) and Tourette's disorder(TD). 6. For the general disorder of a tic and Conners' ADHD rating scale, there was no significance in TTD, CTD and TD. 7. 66% out of the total subjects of 197 cases were found to score more than 65 points in more than 1 items among 8 items such as the time, hearing, wrong alarm, mean response time and standard deviation in the response time, etc. of the ADHD diagnosis system(ADS). 8. The eye blink among motor tics was shown mainly by patients under 10 years old and the frown, movement of the head, shrug and movement of the arms were shown mainly by 11-19 years old patients. Conclusions : For the number, frequency, seriousness and inconvenience in life of tics, TD showed a significantly higher result than TTD and CTD.

베타 용혈성 A군 연구균(group A beta-hemolytic streptococcus)에 의한 류마치스성 열 이후에 Sydenham 무도병이 발현되는 환자 군에서 강박 증상 또는 틱 증상이 나타난다는 보고가 있은 후, A군 연구균 감염과 강박 장애 또는 틱 장애 사이의 관계가 주목받게 되었다. A군 연구균 감염 후에 강박 증상 또는 틱 증상이 유발되는 환자들은 갑작스런 발병과 극적인 증상 악화를 보이고 사춘기 이전에 발병하며 무도병 모양의 운동 및 독특한 양상의 운동 과잉 등의 신경학적 이상을 보이고 또 그 경과가 악화 및 완화를 반복하는 양상을 보인다. 이런 임상적 특징을 보이는 소아 환자 군을 PANDAS(pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections)라고 부르게 되었다. 이후 현재까지 강박 장애와 틱 장애뿐 아니라 주의력 결핍/과잉운동 장애, 신경성 식욕부전증, 신체이형장애 환자들이 PANDAS 범주에 속한다는 보고들이 있어 왔다. 본 증례는 7세까지 정상적인 발달을 보이다가 A군 연구균 감염 수개월 후부터, 인지 기능, 사회성, 언어 및 의사소통에 장애를 보이고 틱 증상과 함께 얼굴과 손발에 이상 운동을 보이는 환자를 기술하였다. 이에 저자들은 본 증례가 소아기 붕괴성 장애의 양상을 보이는 PANDAS 증례라고 생각되어 이를 문헌 고찰과 함께 보고함으로써, PANDAS가 틱 장애, 강박 장애, 주의력 결핍/과잉운동 장애, 신경성 식욕부전증, 그리고 신체이형장애 등의 양상을 보일 뿐 아니라 소아기 붕괴성 장애의 양상을 보일 수 있다는 사실을 보고하고자 한다.

Objectives: The objective of this study was to examine the effects of osmotic-controlled release oral delivery system methylphenidate on changes in regional cerebral blood flow (rCBF) in children with attention-deficit hyperactivity disorder (ADHD) using single photon emission computed tomography (SPECT). Methods: A total of 26 children with ADHD (21 boys, mean age: $9.2{\pm}2.05$ years old) were recruited. Each ADHD participant was examined for changes in rCBF using technetium-99m-hexamethylpropylene amine oxime brain SPECT before and after 8 weeks methylphenidate medication. Brain SPECT images of pediatric normal controls were selected retrospectively. SPECT images of ADHD children taken before medication were compared with those of pediatric normal controls and those taken after medication using statistical parametric mapping analysis on a voxel-wise basis. Results: Before methylphenidate medication, significantly decreased rCBF in the cerebellum and increased rCBF in the right precuneus, left anterior cingulate, right postcentral gyrus, right inferior parietal lobule and right precentral gyrus were observed in ADHD children compared to pediatric normal controls (p-value<.0005, uncorrected). After medication, we observed significant hypoperfusion in the left thalamus and left cerebellum compared to pediatric normal controls (p-value<.0005, uncorrected). In the comparison between before medication and after medication, there was significant hyperperfusion in the superior frontal gyrus and middle frontal gyrus and significant hypoperfusion in the right insula, right caudate, right middle frontal gyrus, left subcallosal gyrus, left claustrum, and left superior temporal gyrus after methylphenidate medication (p-value<.0005, uncorrected). Conclusion: This study supports dysfunctions of fronto-striatal structures and cerebellum in ADHD. We suggest that methylphenidate may have some effects on the frontal lobe, parietal lobe, and cerebellum in children with ADHD.

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.

Objectives : The objective of this study was to evaluate the treatment duration and adherence of osmotic-controlled release oral delivery system (OROS) methylphenidate for treatment of attention-deficit hyperactivity disorder (ADHD). Methods : A total of 843 children with ADHD were recruited : 213 children (25.3%) who had previously taken medications for ADHD and 630 drug-na$\ddot{i}$ve children (74.7%) were recruited. The dosage was adjusted according to the clinician's judgment. The primary efficacy endpoint of this study was treatment retention rate, which was estimated at Week 12 and Week 20 using the Kaplan-Meier curve. The Swanson, Nolan and Pelham-IV (SNAP-IV), Clinical Global Impression-Severity (CGI-S), Clinical Global Impression-Improvement, and the side effect rating scale were measured at every visit. Remission rates were presented based on SNAP-IV and CGI-S, respectively. Results : The treatment retention rate at 12 weeks and at 20 weeks was 76.2% and 66.8%, respectively. Divided according to 6-8, 9-11, 12-14 and 15-18 years of age, younger children tended to show a statistically higher treatment retention rate (p=.02). Based on SNAP-IV and CGI scores, children with better response to medication showed tendencies of statistically higher treatment retention rate. The most common adverse events included loss of appetite (7.1%) and insomnia (3.3%). There was no serious adverse event related to the treatment, such as death. Conclusion : The use of OROS methylphenidate for treatment of ADHD was safe and tolerable for children. In this study, lower age and better treatment response showed a statistically significant relationship with higher treatment adherence. Boys showed a trend of high treatment adherence. The treatment adherence at 20 weeks was satisfactory, however, the treatment adherence after 20 weeks showed a sharp decrease. Therefore, treatment persistence for six months after the beginning of ADHD treatment is important. In addition, the positive role of psycho-education for children and parents is necessary for increasing treatment adherence.
