Managing uncooperative behaviors related to dental treatment is necessary for guiding children and adolescence to more favorable behaviors. The first approach should be controlling their behaviors using non-phamarcologic behavior management techniques. However, if this approach fails, it is helpful to control negative behaviors pharmacologically. Accordingly, sedation is frequently used to relieve anxiety related to dental treatment. Also, general anesthesia has been applied to the situations in which sedation is either ineffective or impossible to gain cooperation during treatment. This article discusses the pharmacology of widely used sedatives for children and adolescence and clinical considerations of managing uncooperative children and adolescence with the use of sedation. Furthermore, we recommend clinical indication of selecting general anesthesia rather sedation for the purpose of behavior management.

While the standard management for posthemorrhagic hydrocephalus (PHH) has not been determined, many patients initially receive temporary treatment such as a ventricular drainage, a ventricular reservoir, or a ventriculosubgaleal shunt. Subsequently, approximately 15% of patients with PHH will require permanent cerebrospinal fluid diversion. Shunt placement is most commonly performed for PHH as permanent treatment. However, shunting still has high complication rates. Since the development of the neuroendoscopic technique has progressed, and indication has been expanded, endoscopic third ventriculostomy with or without choroid plexus cauterization has performed more frequently in recent years in patients with PHH. In this paper, the permanent treatment for PHH will be reviewed based on the latest evidence.

어린이 영구전치의 법랑질 발육 결함이나 고정성 장치에 의한 교정치료 후 탈회 병소는 흔히 심미적 문제를 유발한다. 본 연구는 상악 전치부에 위 원인에 의한 탈회로 인하여 백반양 병소를 보이는 21명 어린이의 38개 치아를 대상으로, 최근 비침습적인 방법으로 소개된 resin infiltration 기법을 적용하고, 병소의 색조의 임상적 개선 효과를 비교, 분석하여 다음과 같은 결과를 얻었다. 1. 1주 후 색조가 개선된 병소는 발육 결함 병소의 25%, 교정 탈회 병소의 61%로 나타났다. 2. 발육 결함 병소의 40%, 교정치료 후 탈회 병소의 6%에서는 시술 전후의 색조변화를 관찰할 수 없었다. 3. 법랑질 발육결함 병소에서는 시술 직후 보다 1주 후에 더 많은 색조 변화를 관찰할 수 있었다. 결과적으로 일부 증례에서는 색조의 극적인 개선이 관찰되었으나, 또 일부 증례에서는 변화가 거의 나타나지 않았는데, 이는 병소 깊이의 차이에 기인한 것으로 사료되었다.

유치의 치수절단술에 사용되는 약제로는 formocresol, ferric sulfate, 수산화칼슘 등이 있다. 그 중에서 formocresol은 치수조직의 고정능력과 높은 임상적 성공을 보임으로써 아직까지 널리 사용되고 있으나 자체독성이 매우 강하여 영구 계승치 치배의 변위나 결손, 법랑질 형성부전, 전신 흡수로 인한 돌연변이 가능성과 암유발 가능성 역시 보고되고 있다. 최근에는 formocresol의 근관내 적용시 불완전한 임시충전에 의한 미세누출로 주위 치은과 치조골의 괴사를 야기한 보고가 있으며 과잉의 formocresol을 적용하였을 경우에도 치조골의 괴사의 원인이 될 수 있다고 하였다. 본 증례는 개인치과에서 formocresol을 이용한 치수치료를 받은 후 지속되는 동통으로 인해 상악 좌측 제 2유구치를 발거하였으나, 증상이 개선되지 않아 본원에 의뢰되었다. 환아는 8세 남아로 심한 구취 및 계승 영구치 치관 주위로 환형의 치조골 괴사를 보여 부골절제술을 시행하고 1년 7개월간 관찰을 하였을 때 정상적인 치근 성장은 이루어졌으나 결손된 치조골 및 부착치은의 완전한 조직재생 소견은 관찰되지 않았다. Formocresol에 의한 치주조직에 대한 부작용은 비가역적이므로 formocresol의 사용에 있어 적응증 여부를 잘 판단해야 하며, 철저한 임시 가봉에 주의를 기울여야 할 것이다.

The aim of this study was to evaluate the appropriateness of some kinds of surgery and admission, such as cesarean section (C/S), cholecystectomy, and pediatric pneumonia. For appropriateness evaluation, we ourselves developed some criteria, which were included in the category of explicit and linear criteria, with the assistance of specialists of relevant clinical field. The evaluation of appropriateness was performed by two family physicians. The major findings were as follows: 1. For cesarean section, 77.6% of deliveries were determined to be 'appropriate', but the level of appropriateness was not significantly different among hospitals and between hospital groups by size. The most freqeunt indication of C/S was repeated operation, followed by cephalopelvic disproportion (CPD). The labor trials for vaginal delivery among repeated C/S and CPD cases were performed in 24.5% of pertinent deliveries. 2. About 73.8% of cholecystectomy cases was appropriate to one of the surgical indications, without significant differences among hospitals. Of surgical indications, 'sufficiently frequent and intense symptom recurrence' was the most frequent, and 'confirmed acute cholecystitis' was the second. 3. Of children admitted due to pneumonia, only 57.4% of cases satisfied admission criteria, and the level of appropriateness of admission was different among hospitals. The common reasons fur admission were 'failure to initial treatment', 'suspected bacterial pneumonia', 'young infant', etc. We could find that there were differences of quality among hospitals in some procedures, especially in the pediatric pneumonia and labor trial before C/S, which suggested that the implementation of quality assurance activiteis would be necessary in this country. In this study, we used some simple and primitive research tools and the numbers of subjects and tracer procedures were limited. So advanced studios with plentiful subjects and more representative diseases or procedures should be tried.

Purpose: Celiac disease is a common non-communicable disease with varied presentations. Purpose of this study was to find the duodeno-endoscopic features in celiac disease and to compare duodeno-endoscopic and histological findings between typical and atypical celiac disease in children. Methods: Hospital based observational study was conducted at Sir Padampat Mother and Child Health Institute, Jaipur from June 2015 to May 2016. Patients were selected and divided in two groups- typical and atypical celiac disease based upon the presenting symptoms. Upper gastrointestinal endoscopy and duodenal biopsy was performed for serology positive patients. Results were analysed using appropriate statistical test of significance. Results: Out of 101 enrolled patients, 47.5% were male. Age ranged from 1 to 18 years. Study showed that 54.5% were typical and 45.5% were atypical. Patients presenting with atypical symptoms were predominantly of older age group. On endoscopy, scalloping, mosaic pattern, reduced fold height and absent fold height; and in histology, advanced Marsh stage were significantly higher in the typical group. Conclusion: Awareness of atypical presentations as well as duodeno-endoscopic features may have considerable practical importance for the diagnosis of celiac disease in children. Scalloping, mosaic pattern, reduced fold height and nodularity are main endoscopic markers of celiac disease in children. Endoscopic markers of duodenal mucosa may be important in early diagnosis of celiac disease, in children subjected to endoscopy for atypical presentations or indication other than suspected celiac disease.

치면열구전색은 잘 시행하지 못한 경우 오히려 우식발생을 가릴 수 있어 위험하다. 따라서 치면열구전색의 올바른 적용방법에 대한 이해와 재고가 필요하다. 치면열구전색 시행하기 위해서는 반드시 recall-check이 전제되어야 하는데, 치면열구전색재 시술 환자의 70%가 recall이 되었을 때 병원 경영이 효율적으로 이루어지고 있다는 평가를 내릴 수 있다. 치면열구전색재 도포시 임상가들이 가장 관심 있게 추구하는 2가지 사항은 첫째 치면열구전색재가 소와 및 열구내로 깊숙이 침투하도록 하는 것과 둘째 치면열구전색재와 치면 사이의 gap(변연누출, marginal leakage)을 최소로 발생하게 하는 것이다. 이는 모두 치면열구전색재의 유지력을 좋게 하기 위한 것이며 이는 치면열구전색의 성공/실패와 직결된다. 그러나 탈락되지 않게 할 수는 없어도 더 오랫동안 붙어 있도록 하는 노력은 필요하다. 본 종설에서는 치면열구전색재 유지력을 강화하기 위한 방법으로 치면열구전색재의 재료학적 검토, 유지력에 관계되는 요소, 교합면 소와 및 열구 세척 소와와 열구 내로의 침투도를 높이는 방법, 미세누출을 줄일 수 있는 임상 기술 등에 대해 살펴보고자 하였다. 치면열구전색재의 유지력에 관여되는 요소가 매우 많고 다양하므로 이에 대한 기본적인 이해와 함께 도포 과정에서의 술자의 섬세함과 정성이 전제되어야 한다.

Purpose: To design a prospective study on endovascular closure of congenital portosystemic shunts. The primary endpoint was to assess the safety of endovascular closure. The secondary endpoint was to evaluate the clinical, analytical and imaging outcomes of treatment. Methods: Fifteen patients (age range: 2 days to 21 years; 10 male) were referred to our center due to congenital portosystemic shunts. The following data were collected prior to treatment: age, sex, medical history, clinical and analytical data, urine trimethylaminuria, abdominal-US, and body-CT. The following data were collected at the time of intervention: anatomical and hemodynamic characteristics of the shunts, device used, and closure success. The following data were collected at various post-intervention time points: during hospital stay (to confirm shunt closure and detect complications) and at one year after (for clinical, analytical, and imaging purposes). Results: The treatment was successful in 12 participants, migration of the device was observed in two, while acute splanchnic thrombosis was observed in one. Off-label devices were used in attempting to close the side-to-side shunts, and success was achieved using Amplatzer™ Ductus-Occluder and Amplatzer™ Muscular-Vascular-Septal-Defect-Occluder. The main changes were: increased prothrombin activity (p=0.043); decreased AST, ALT, GGT, and bilirubin (p=0.007, p=0.056, p=0.036, p=0.013); thrombocytopenia resolution (p=0.131); expansion of portal veins (p=0.005); normalization of Doppler portal flow (100%); regression of liver nodules (p=0.001); ammonia normalization (p=0.003); and disappearance of trimethylaminuria (p=0.285). Conclusion: Endovascular closure is effective. Our results support the indication of endovascular closure for side-to-side shunts and for cases of congenital absence of portal vein.

Data exclusivity is one of the most important intellectual property rights of pharmaceuticals. During data exclusivity period, third parties are prohibited from relying on the data which the original company has submitted to regulatory authority for drug application. I investigated data exclusivity systems for pharmaceuticals in the US, EU, Canada and Korea. New chemical entities were usually given the longest periods of data exclusivity compared to drugs with new indication or new formulation, although the protection periods varied by country. For new drugs to be entitled to a data exclusivity, strict conditions should be met. Data exclusivity has also been provided as an incentive to promote clinical investigation and drug development for pediatric population or orphan diseases. In Korea, data exclusivity was adopted in 1995 as an additive provision to "drug re-examination" which is to investigate post-marketing safety information of new drugs. It was introduced with few discussion on the purposes or effects of data exclusivity on pharmaceutical industry and pharmaceutical market in this country. I found that Korea's data exclusivity system falls short of considerations on valuing innovation of pharmaceutical research. It is necessary to improve data exclusivity system in order to promote innovative pharmaceutical development and to balance intellectual property rights protection and access to drugs in this country.

유구치의 깊은 우식은 치수병소을 유발하고 이를 조기에 치료하지 않을 경우에는 치수강저의 수많은 부근관을 통하여 치근분지부 병소로 이어진다. 지금까지 대부분의 교과서나 문헌에서는 이와 같은 경우를 발치의 적응증으로 기술하여 왔고 임상에서도 상례적으로 발치를 흔히 시행하였다. 그러나 유구치의 조기 상실은 수많은 부작용을 낳는 것이 필연적이다. 어린이의 골재생 능력 이 우수하며, 치수강저와 치근분지부를 잇는 많은 부근관이 있음을 생각해 볼 때 유구치 치수 내의 감염원을 치수절제술로 제거하고, 이미 발생한 치근분지부 병소에 대해서는 소파술을 시행한다면 치근분지부 골조직의 신속한 재생이 가능하지 않을까 하는 의문이 제기되었다. 본 증례는 $3{\sim}6$세 어린이에서 유구치 치근분지부 방사선 투과상이 $2{\sim}4mm$ 정도의 깊이를 보이는 비교적 경미한 수준이면서, 연조직 누공을 보이는 10개 증례를 선별하여 치수절제술과 치근분지부 소파술을 시행한 결과, 모두에서 방사선적으로 골재생이 관찰되었다. 이를 통하여 유구치 치근분지부 병소나 누공을 보이는 모든 경우가 발치의 적응증은 아니며, 이 방법이 치근분지부 병소를 가진 유구치를 잔존시킬 수 있는 하나의 대안이 될 수 있음을 알 수 있었다. 그러나 이 방법이 객관적 인 타당성을 얻기 위해서는, 병소의 크기와 진행정도, 계승 영구치의 성숙도, 환아의 연령 등 적응증에 대한 보다 심층적인 검토와 연구가 필요할 것으로 사료되었다.
