The endoscopic endonasal approach (EEA) has been popularized in adults and has been applied to an expanding range of surgical modules and indications in this population. However, its clinical application in pediatric neurosurgery has been impeded by the differences in anatomical features and the relatively low incidence of diseases to which it is applicable. In this review article, we mainly discuss the surgical indications, feasibility, and complications of EEA for suprasellar lesions in children based on a review of the literature, focusing especially on the age-related anatomical features of the nasal cavity, various pathologic entities, and the impact of EEA on long-term craniofacial growth.

Neuroendoscopic surgery is performed because it causes minimal damage to normal structures, carries a lower rate of complications, and achieves excellent outcomes. Surgeons using an endoscope and related instruments can perform complex operations through very small incisions, which is especially useful for minimally invasive procedures for the brain and spine. Neuroendoscopic surgery is now performed in cases of obstructive hydrocephalus, various intraventricular lesions, hypothalamic hamartomas, craniosynostosis, skull base tumors, and spinal lesions. This review discusses the brief history of neuroendoscopy and the current state and future perspectives of endoscopic surgery.

NPHP is the most common monogenic cause of CKD in children or adolescents. Extra-renal symptoms often accompany, therefore examination of retina, hearing, and skeleton is necessary in patients with CKD with insidious onset. Genes involved in NPHP-RC are mostly related in primary cilia. While genetic diagnosis is necessary for definitive diagnosis, there is no curative treatment.

Objectives: Alcohol problems of parents have an influence on not only their psychological problems but also on their children's psychosocial adaptation. The purpose of this study was to compare the emotional and behavioral problems, including school bullying and social skills, between children of alcoholics (COAs) and children of non-alcoholics (non-COAs). Methods: We recruited $4^{th}$ grade children (n=741) from 7 primary schools in Seoul and their parents as subjects. The self-rated psychiatric symptoms were assessed with the Korean version of the Children of Alcoholics Screening Test (CAST-K), the Children's Depression Inventory (CDI), the Rosenberg's Self-esteem Scale (RSES), the School Bullying Scale, the Social Skill Rating Scale and the Korean version of Alcohol Expectancy Questionnaire-Adolescent (AEQ-A). The Attention-deficit Hyperactivity Disorder Rating Scale-IV (ARS) was completed by the parents. Results: 518 children were non-COAs and 223 were COAs. The COAs showed higher CDI and ARS-IV scores and lower RSES scores than the non-COAs. Especially, the COAs also showed higher school bullying scale scores and lower cooperative scale scores on the social skill rating scales. But there was no difference of alcohol expectancy between the COAs and non-COAs. Conclusion: It was plausible that the COAs had more behavioral & psychosocial problems than the non-COAs among the school aged children. It is important to identify and intervene to solve the problems of peer relationships of school age COAs in order to prevent victimization by bullying and to improve psychosocial adaptation.

Purpose: To evaluate the clinical characteristics of vitamin D deficiency and its association with iron deficiency anemia (IDA). Methods: A total of 171 children aged less than two years underwent 25-hydroxyvitamin $D_3$ tests between January 2007 and July 2009. The study was classified into two groups: normal and vitamin D insufficiency, by their vitamin 25-hydroxyvitamin $D_3$ levels. Results: In total, 120 children were in the normal group (mean age, body weight and heights $12.5{\pm}7.0$, $9.3{\pm}0.9$ kg and $76.8{\pm}1.1$ cm), and 51 children in the vitamin D insufficiency group ($9.9{\pm}5.4$ months, $9.0{\pm}0.9$ kg and $75.1{\pm}0.9$ cm). Vitamin D insufficiency was most commonly diagnosed in the spring (44%). The proportion of complete breast-feeding was higher in the insufficiency (92%), and 25.5% of the children in the deficient group also experienced IDA compared that 12% of normal group. Ten children in the insufficiency group experienced bony changes. Six children received calcitriol medication in the normal group, in whom the mean vitamin 25-hydroxyvitamin $D_3$ level increased from $39.6{\pm}14.6$ ng/mL (pre-medication) to $41.8{\pm}17.2$ ng/mL (post-medication), and 13 in the insufficiency group, in whom the mean vitamin 25-hydroxyvitamin $D_3$ increased from $20.7{\pm}7.0$ ng/mL to a mean post-treatment level of $43.7{\pm}23.8$ ng/mL. Conclusion: This study demonstrated that approximately 30% of children aged ${\leq}2$ years experienced vitamin D insufficiency associated with subclinical rickets. Many children also experienced concurrent IDA. Guidelines for vitamin D supplement in such children must therefore be established.

Background: It is imperative that adequate sedation level should be maintained for safe and effective dental sedation. Cerebral state index (CSI) is a empirically derived parameter calculated from the processed electroencephalography (EEG). We investigated whether CSI can be used as a sedation depth indicator. Methods: We continuously recorded CSI and bispectral index (BIS) values from 10 healthy children aged 3.6 yr undergoing dental sedation. We also evaluated sedation level using the Modified Observer's Assessment of Alertness/Sedation (MOAA/S). The correlation between CSI and BIS, or CSI and sedation score were sought a regression analysis. Results: There were good linearity between CSI values and sedation score. (r = 0.916, P < 0.001) The paired CSI and BIS values showed a significant correlation between the two values. (r = 0.895, P < 0.001) The difference between CSI and BIS values was not statistically significant at deep and conscious sedative levels. Conclusions: The CSI monitor can be easy to monitor sedation depth during dental sedation for children.

Purpose : This study was performed to identify longitudinal changes in the prevalence of organisms isolated from urinary tract infection(UTI) and in the pattern of Escherichia coli susceptibility to antibiotics during the past 10 years in children with UTI. Methods : We performed a retrospective study of a total of 192 urine cultures from children with UTI in the Department of Pediatrics, Seoul Adventist Hospital over two periods(1st: 1995-2000, 2nd:2001-2005). Antimicrobial susceptibility of the isolates was compared between the two groups. Results : The pathogens of UTI in the two groups were similar. In the first period, E. coli was the leading uropathogen(66.2%) followed by Klebsiella pneumoniae(7.8%), Enterobacter cloacae(6.5%), and others(19.5%). In the second period, E. coli was the leading uropathogen(67%) followed by K. pneumoniae(12.2%), E. cloacae(3.5%), Enterobacter aerogenes(3.5%), and others(13.8%). The susceptibility pattern of E. coli to amoxicillin/clavulanate(87.5%, 81.0%) did not present any statistically significant difference between the two periods(P>0.05). The susceptibility of E. coli to TMP/SMX(52.4%, 50.0%) was still low with no significant difference between the two periods(P>0.05). Conclusion : Our results suggest that the use of amoxicillin/clavulanate is still an excellent therapeutic option in children with UTI. The low rate of susceptibility to TMP/SMX against uropathogens suggest that TMP/SMX may be reevaluated as the first-line therapeutic drug for UTI.

Purpose: This study aims to investigate the clinical characteristics of children diagnosed with the novel influenza A (H1N1) in the winter of 2009 at a single medical institution. Methods: Out of 545 confirmed cases of influenza A (H1N1) in children, using the real time RT-PCR method at Kosin University Gospel Hospital from September to December of 2009, 149 patients and their medical records were reviewed in terms of symptoms, laboratory findings, complications and transmission within a family. Results: Median age of subjects was 7 years (range: 2 months-18 years). New cases increased rapidly from September to reach a peak in November, then declined rapidly. Most frequently observed symptoms were fever (96.7%), cough (73.2%), rhinorrhea (36.9%) and sore throat (31.5%). Average body temperatures on the 1st, 2nd and 3rd hospital day were $38.75{\pm}0.65^{\circ}C$, $38.08{\pm}0.87^{\circ}C$ and $37.51{\pm}0.76^{\circ}C$, respectively. Complete blood counts and biochemical tests performed on the first admission day showed within the reference values in most cases. Of the 82 patients with simple chest radiography, 18 (22%) had pneumonic lesions; multi-focal bronchopneumonia in eleven, single or multi-segmental lobar pneumonia in five, and diffuse interstitial pneumonia in two patients. All of the 149 patients improved from their symptoms and discharged within 9 days of admission without any late complication. Conclusion: Children with 2009 pandemic influenza A (H1N1) at our single institution displayed nonspecific symptoms and laboratory findings, resembling those of common viral respiratory illnesses, and did not appear to develop more severe disease.
