Abstract
The High energy Engineering X-ray (HEX) diffraction beamline at the National Synchrotron Light Source II (NSLS-II) at Brookhaven National Lab (BNL) is the first high-energy beamline capable of reaching 200 keV for a monochromatic beam. With the 3 GeV electron beam energy for the NSLS-II ring, only the superconducting wiggler (SCW) producing greater than 4 T peak field can cover these ranges with a sufficient number of photons. The 1.2 m-long HEX-SCW has a period length of 70 mm and a field strength on-axis of 4.3 T. It utilizes no liquid helium, and the vertical aperture size of the electron beam vacuum chamber is 8 mm. Unlike regular undulators/wigglers, there is no standard configuration for the magnetic measurement system for superconducting insertion devices. The NSLS-II Insertion Devices group has developed, in collaboration with the vacuum group, a novel in-vacuum Hall mapper with a 1.75 m in-vacuum linear motor and an in-vacuum flip coil system utilizing many commercial-off-the-shelf products. The measurements were conducted at the BNL, and the device was installed in the ring and commissioned. This paper provides a description of the SCW and its magnetic measurement systems, as well as a brief account of the installation and commissioning efforts.

Abstract
OBJECTIVE Reversible splenium lesions during febrile illness (RESLEF) are found in a spectrum. There are two types of corpus callosum (CC) lesions: CC-only type, with limited lesions and the CC (+) type, with extensive white-matter lesions. This retrospective study aimed to describe the differences in clinical findings between CC-only and CC (+) lesions and the association between onset age and clinico-radiological features in RESLEF. METHODS Fifty-two episodes of CC-only or CC (+) lesions accompanied by neurological symptoms, e.g., seizures, delirious behavior (DB), and disturbance of consciousness (DC), from January 2008 to October 2019 were included. We analyzed the etiology (pathogen), clinical course, laboratory data, magnetic resonance imaging and electroencephalography findings, therapy, and prognosis. RESULTS The rate of DC in the CC (+) was significantly higher than that in the CC-only group (5/6 [83%] vs 7/46 [15%]; p = 0.0016). The median number of seizures in the CC (+) was also significantly higher than that in the CC-only group (4 [0-7] vs 0 [0-7]; p = 0.034). Further, in RESLEF, the median onset age (months) in the seizure was significantly lower than that in the no-seizure group (39 [12-74] vs 83 [28-174]; p = 0.0007). The median onset age (months) in the DB was significantly higher than that in the no-DB group (74.5 [26-174] vs 28 [12-139]; p = 0.003). CONCLUSIONS In RESLEF, CC (+) is a more severe neurological symptom than CC-only. Furthermore, the onset age is related to the type of neurological symptoms that appear.

Abstract
BACKGROUND Chronic subdural hematoma (CSDH) with cerebrospinal fluid hypovolemia syndrome (CHS) remains refractory to standard treatment with hematoma drainage by burr hole and irrigation and/or epidural blood patch. Previously, we reported the utility of middle meningeal artery (MMA) embolization for intractable CSDH. In this study, we present the usefulness of MMA embolization as a treatment for CSDHs with CHSs. CASES We present two cases of CSDHs with CHSs occurring in patients, 1 treated with burr hole craniotomy and irrigation, and the other treated with the epidural blood patch. Both patients exhibited similar-appearing bilateral relatively-thin hematomas, hyperplasia, and enhanced contrast effects in the dura mater, and extradural hygroma in the cervical portion on enhanced magnetic resonance imaging scans. Also, to reviewing prior literature and imaging findings, they had already undergone conventional treatment. We added MMA embolization treatment and they followed a good course. RESULTS Despite the known intractable outcomes of patients with CSDHs with CHSs, MMA embolization worked well in the current case series. CONCLUSION MMA embolization might be considered as a preferred therapeutic option for CSDHs with CHSs in order to buy time before the epidural blood patch starts working.

Abstract
BACKGROUND Rapid-onset dystonia-parkinsonism (RDP) is a disease characterized by an abrupt onset of dystonia accompanied by signs of parkinsonism and prominent bulbar symptoms. CASE REPORT We describe a case of a female patient, born after normal delivery, but diagnosed with mild intellectual disability at age 7. She presented with an abrupt onset of upper limb dystonia and bradykinesia without tremor in parkinsonism, as well as dysarthria and dysphagia caused by prominent bulbar symptoms, at age 9. She had normal findings on brain magnetic resonance imaging, electroencephalography, and blood examination but was diagnosed with a psychogenic disorder. At age 10, she developed left lower limb paroxysmal stiffness with pain, and at 14, she was hospitalized due to lasting paroxysmal symptoms. Whole-exome sequencing was performed for this index case and her parents, and a de novo missense variant c.829G > A, p.Glu277Lys in ATP1A3 was identified. DISCUSSION This RDP case highlights a rare clinical feature of paroxysmal dystonia that affects the lower left limb and develops after the abrupt onset of permanent dystonia. Currently, there are only three reported RDP cases associated with the same missense mutation, and we summarized the clinical features of all cases including ours, such as onset of age, time for stable, RDP score, relapse and exacerbation. Various symptoms owing to ATP1A3 mutation could develop as ATP1A3-related neurological disorders beyond classical phenotypes such as alternating hemiplegia of childhood (AHC) or RDP. Although RDP is extremely rare during childhood, it is important to understand its clinical characteristics in children.

Abstract
OBJECTIVE Febrile seizures (FSs) typically occur in infants and children between 6 and 60 months of age. Rarely, FS can occur in late childhood (late FS [LFS]; >5 years of age); however, the clinical features of LFS remain unclear. We aimed to clarify the clinical features of LFS. METHODS We retrospectively analyzed data from patients with LFS who visited Hirakata City Hospital between January 2004 and December 2014. We defined LFS as a seizure accompanied by fever (temperature ≥38 °C) occurring after 5 years of age, without a central nervous system infection. RESULTS A total of 505 patients (349 boys, 156 girls: 5-14 years old) were included. A history of FS before 60 months of age was observed in 319 of 460 patients (69.3%) with sufficient information about previous FS history among the 505 patients enrolled. LFS was more likely to occur in males (69.1%). Seizure duration was ≤15 min in 87.4% of cases. A family history of FS in first-degree relatives was observed in 103/327 cases (31.5%). Among LFS cases, 45% occurred at 5 years of age, and 92.1% experienced only one seizure after 5 years of age. The number of seizure episodes gradually lessened with age, decreasing drastically to 5.6% of cases older than 9 years. CONCLUSIONS Our findings suggest that sex differences, seizure duration, and family history were similar for LFS and FS. Over 90% patients with LFS experienced no recurrence after 5 years of age. Further study is needed to verify the recurrence rate of LFS.

Abstract
OBJECTIVE To investigate the effect of guidelines for management of febrile seizures on the clinical practice, we conducted a nationwide survey in Japan. METHODS The Japanese guidelines for management of febrile seizures 2015 (GL2015) was released in 2015. In 2016, a questionnaire was sent to all 512 certified hospitals (3 pediatricians each) of the Japan Pediatric Society and all 47 prefecture Pediatric Associations (10 private pediatricians each) in Japan asking about management policies for febrile seizures (FSs) during 2013-2014 and 2016. The questionnaires were about the following procedures: (1) lumbar punctures, blood examinations, and diazepam suppositories for children after a first simple FS at emergency departments; and (2) prophylactic diazepam during febrile illnesses in children with two or three past simple FSs, with no known predictors of recurrence. RESULTS A total of 1327 pediatricians (66.2%) answered the questionnaire. Numbers of pediatricians performing lumbar punctures and blood examinations, and giving diazepam suppositories after a first simple FS were less in 2016 than in 2013-2014 (1.2% and 2.0%, 53.1% and 61.3%, and 36.7% and 51.9%, respectively). Pediatricians recommending prophylactic diazepam for children with two and three FSs decreased from 45.7% and 82.4% in 2013-2014 to 31.0% and 65.0% in 2016, respectively. CONCLUSION GL2015 had an effect on the clinical practices of pediatricians. On the other hand, 65% recommended prophylactic diazepam to children with three simple FSs even though GL2015 did not recommend use of diazepam based on number of previous FS. Anxiety about frequent seizures may affect pediatricians' clinical practice.

Abstract
OBJECTIVES To confirm the safety of using acetaminophen for febrile seizures (FSs) and to assess its efficacy in preventing FS recurrence during the same fever episode. METHODS In this single-center, prospective, open, randomized controlled study, we included children and infants (age range: 6-60 months) with FSs who visited our hospital between May 1, 2015, and April 30, 2017. The effectiveness of acetaminophen was examined by comparing the recurrence rates of patients in whom rectal acetaminophen (10 mg/kg) was administered every 6 hours until 24 hours after the first convulsion (if the fever remained >38.0°C) to the rates of patients in whom no antipyretics were administered. No placebo was administered to controls. The primary outcome measure was FS recurrence during the same fever episode. RESULTS We evaluated 423 patients; of these, 219 were in the rectal acetaminophen group, and 204 were in the no antipyretics group. In the univariate analysis, the FS recurrence rate was significantly lower in the rectal acetaminophen group (9.1%) than in the no antipyretics group (23.5%; P < .001). Among the variables in the final multiple logistic regression analysis, rectal acetaminophen use was the largest contributor to the prevention of FS recurrence during the same fever episode (odds ratio: 5.6; 95% confidence interval: 2.3-13.3). CONCLUSIONS Acetaminophen is a safe antipyretic against FSs and has the potential to prevent FS recurrence during the same fever episode.

Abstract
AIMS To identify factors predicting early postpartum glucose intolerance in Japanese women with gestational diabetes mellitus, using decision-curve analysis. METHODS A retrospective cohort study was performed. The participants were 123 Japanese women with gestational diabetes who underwent 75-g oral glucose tolerance tests at 8-12 weeks after delivery. They were divided into a glucose intolerance and a normal glucose tolerance group based on postpartum oral glucose tolerance test results. Analysis of the pregnancy oral glucose tolerance test results showed predictive factors for postpartum glucose intolerance. We also evaluated the clinical usefulness of the prediction model based on decision-curve analysis. RESULTS Of 123 women, 78 (63.4%) had normoglycaemia and 45 (36.6%) had glucose intolerance. Multivariable logistic regression analysis showed insulinogenic index/fasting immunoreactive insulin and summation of glucose levels, assessed during pregnancy oral glucose tolerance tests (total glucose), to be independent risk factors for postpartum glucose intolerance. Evaluating the regression models, the best discrimination (area under the curve 0.725) was obtained using the basic model (i.e. age, family history of diabetes, BMI ≥25 kg/m2 and use of insulin during pregnancy) plus insulinogenic index/fasting immunoreactive insulin <1.1. Decision-curve analysis showed that combining insulinogenic index/fasting immunoreactive insulin <1.1 with basic clinical information resulted in superior net benefits for prediction of postpartum glucose intolerance. CONCLUSIONS Insulinogenic index/fasting immunoreactive insulin calculated using oral glucose tolerance test results during pregnancy is potentially useful for predicting early postpartum glucose intolerance in Japanese women with gestational diabetes.

Abstract
BACKGROUND Neurological sequelae occur in 40% of patients with acute encephalopathy (AE). The early prediction of poor outcomes is critical to the initiation of appropriate treatment. The aim of the present study was therefore to elucidate prognostic factors that can be quickly and feasibly evaluated on hospital admission in patients with AE. METHODS We analyzed data from 51 AE patients admitted to Hirakata City Hospital between January 2005 and December 2014. Age at onset, sex, underlying disease, status epilepticus (SE), presence of benzodiazepine-resistant SE (BZD-resistant SE), and basic blood serum parameters on admission were evaluated in relation to each patient's outcome. RESULTS On univariate analysis age at onset, BZD-resistant SE, and serum aspartate aminotransferase (AST), alanine aminotransferase, lactate dehydrogenase, and platelet count varied significantly according to outcome. On multivariate analysis age at onset (≤21 months), presence of BZD-resistant SE, and AST (≥46 IU/L) were identified as independent variables associated with poor outcome. CONCLUSION Age at onset, presence of BZD-resistant SE, and AST are associated with a poor prognosis in AE.

Abstract
PURPOSE Report of a case with retinal neovascularization developing in the setting of diabetic retinopathy despite complete posterior vitreous detachment (PVD). CASE REPORT A 76-year-old man had had type II diabetes mellitus for more than 30 years. Weiss' ring was detected by direct and indirect ophthalmoscopy. PVD was thus considered to be complete. On the other hand, fluorescein angiography showed two areas of hyperfluorescence at the margin of the retinal nonperfusion area. CONCLUSIONS The present case underscores the importance of periodic follow-up using fluorescein angiography, given the probability of retinal neovascularization development and proliferative changes for many years even in diabetic retinopathy associated with complete PVD.

In 2015, the Japanese Society of Child Neurology released new guidelines for the management of febrile seizures, the first update of such guidelines since 1996. In 1988, the Conference on Febrile Convulsions in Japan published "Guidelines for the Treatment of Febrile Seizures." The Task Committee of the Conference proposed a revised version of the guidelines in 1996; that version released in 1996 was used for the next 19years in Japan for the clinical management of children with febrile seizures. Although the guidelines were very helpful for many clinicians, new guidelines were needed to reflect changes in public health and the dissemination of new medical evidence. The Japanese Society of Child Neurology formed a working group in 2012, and published the new guidelines in March 2015. The guidelines include emergency care, application of electroencephalography, neuroimaging, prophylactic diazepam, antipyretics, drugs needing special attention, and vaccines. While the new guidelines contain updated clinical recommendations, many unsolved questions remain. These questions should be clarified by future clinical research.

Abstract
Amelogenin is the major enamel matrix component in developing teeth. In eutherian mammals, amelogenin is expressed from the X chromosome only, or from both the X and Y chromosomes. Two classes of porcine amelogenin cDNA clones have been characterized, but the chromosomal localization of the gene(s) encoding them is unknown. To determine if there are sex-based differences in the expression of porcine amelogenin, we paired PCR primers for exons 1a, 1b, 7a, and 7b, and amplified enamel organ-derived cDNA separately from porcine males and females. The results show that exons 1a/2a and 7a are always together and can be amplified from both males (XY) and females (XX). Exons 1b/2b and 7b are also always paired, but can be amplified only from females. We conclude that porcine amelogenin is expressed from separate genes on the X and Y chromosomes, and not, as previously proposed, from a single gene with two promoters.

Abstract
The mechanism of post-vaccination acute disseminated encephalomyelitis (ADEM) has been hypothesized as resulting from vaccination-injected antigens cross-reacting with myelin components, however, a precise etiology has been uncertain. In this report, we describe the case of a 6-year-old Japanese boy who had multiphasic disseminated encephalomyelitis (MDEM), and was positive for both anti-myelin oligodendrocyte glycoprotein (MOG) antibodies and Chlamydophila pneumoniae antibodies. After vaccinations that were the second one for measles and rubella, and the booster immunization for Japanese encephalitis, the patient presented with fever, headache, vomiting, and a change in personality. He was treated with a high-dose of intravenous methylprednisolone in the diagnosis of ADEM. However, these symptoms recurred with different magnetic resonance imaging lesion, and he was diagnosed as MDEM. Retrospective testing for pathogens revealed C. pneumoniae IgM and IgG antibodies, and it was considered that he was infected with C. pneumoniae subclinically. The patient's serum indicated a positive response for the anti-MOG antibody from the onset of the ADEM diagnosis and in all recurrent episodes. Chlamydia species infection has been known to play a role in demyelinating diseases. It is also known that the anti-MOG antibody may be present but not exhibit its pathogenesis in the absence of a cell-mediated inflammatory response; however, the precise mechanism of action of the anti-MOG antibodies is not yet determined. We propose the possibility that post-vaccination demyelinating disease may result from the synergistic effects of a preceding anti-MOG antibody, possibly produced in response to a subclinical Chlamydia species infection.

Abstract
Objective: Patients with childhood-onset epilepsy often need continued epilepsy treatment into adulthood. We investigated parents’ opinions of the changes in their children’s epilepsy treatment during the transition from childhood to adulthood using questionnaires and formulated agendas to build the appropriate medical treatment system for epilepsy. Methods: We distributed questionnaires to parents of patients with epilepsy who were 12 to 18 years old. Results: We distributed 176 questionnaires, and analyzed 79 (45%) questionnaires. Most parents (59%) wanted their child to continue treatment for epilepsy in the pediatrics department because of confidence in the current treatment environment. Most parents (73%) were anxious about their child not being treated in the pediatrics department during future epilepsy medical treatments because of concerns about whether a proper handover from the pediatrics department to other departments is possible. No parent was recommended the departmental transition by the primary pediatrician to other courses for future epilepsy treatment, while 19% of par-ents had a sense of incongruity regarding epilepsy treatment at the current pediatrics department. Parents who were anxious about future epilepsy treatments had significantly fewer general-school students than parents without anxiety. In addition, their children had more seizures than children of parents who were not anxious. Furthermore, they wanted their child to continue treatment for epilepsy in the pediatrics department more than the parents without anxiety. Conclusions: Approximately 70% of the parents were anxious about obtaining future epilepsy treatment in clinical departments other than the pediatrics department. To build a satisfactory medical treatment system for patients with epilepsy having different backgrounds and requiring continued treatment in adulthood, it is important to create a cooperating network consisting of pediatricians, neurologists, neurosurgeons, psychiatrists, and epileptologists.

Abstract
BACKGROUND The goals of this study, conducted in our secondary emergency care hospital, were to assess the effectiveness of targeted temperature management (TTM) for acute encephalopathy secondary to status epilepticus and to consider appropriate adaptations for use of TTM in this setting. METHODS Medical records of patients admitted with acute encephalopathy to Hirakata City Hospital between January 2010 and December 2014 were retrospectively reviewed. Cases treated with TTM (36 °C) and methylprednisolone pulse (MP) therapy (TTM/MP) were compared with those treated with conventional MP regarding clinical courses and outcomes. RESULTS In total, 20 children were retrospectively enrolled. In the TTM/MP group (10 cases) all survived intact. In the MP group (10 cases), 4 cases were left with neurological sequelae. Furthermore, in the TTM/MP group, the body temperature dropped more quickly. For pediatricians in this secondary emergency hospital, implementing the body temperature management system was not difficult. There were no complications caused by hypothermia. DISCUSSION Use of TTM as the initial treatment for acute encephalopathy in the early-onset stage is possible in a secondary emergency care hospital. However, some acute encephalopathy cases are the so-called fulminant type; DIC or shock develops soon after onset and so it is sometimes difficult to introduce TTM. Fulminant-type patients should be transported to tertiary emergency care hospitals. Secondary emergency care hospitals must carefully select cases for TTM, keeping the possibility of transport to a tertiary emergency hospital in mind at all times.

Abstract
BACKGROUND The aim of this study was to assess the rate of response to long-term low-dose levetiracetam (LEV) treatment and the clinical factors associated with response. METHODS The response to low-dose LEV of 43 patients with epilepsy (22 male, 21 female; age range, 5-39 years; median age, 13 years) was retrospectively assessed. Patients aged <15 years received <20 mg/kg/day LEV, whereas those aged ≥15 years received <1000 mg/day LEV. Clinical features were compared between responders to low-dose LEV, responders to the recommended dose, and non-responders. RESULTS Of the 43 patients who received low-dose LEV, 13 (30%) showed improvement, defined as seizure cessation or >75% seizure reduction over 6 months for patients with monthly, weekly, and daily seizures; and over 1 year for patients with yearly seizures. Efficacy was maintained for >1 year in 10 (77%) of the 13 patients. Long-term response to low-dose LEV was significantly associated with older age at onset and fewer previous treatments with ineffective anti-epileptic drugs. All patients showing long-term response to low-dose LEV developed only focal seizures. CONCLUSIONS Titration of LEV starting from a low dose may be effective in selected patients. Once patients respond to low-dose treatment, maintenance of the effective dosage may prolong response.

Abstract
Multiple sclerosis (MS) is a syndrome characterized by complex neurological symptoms resulting from demyelinating lesions in the central nervous system. We report a child with a relapse of MS whose only presenting symptom was severe abdominal pain. Dysfunctional intestinal mobility was assessed by abdominal computed tomography. Findings resembled paralytic ileus resulting from peritonitis. However, the patient demonstrated no other symptoms of peritonitis. A T2-weighted magnetic resonance image revealed a new demyelinating lesion localized to thoracic segments T4-T12. The lesion presumably affected autonomic efferents involved in intestinal mobility. Treatment with a pulse of methylprednisolone reduced both abdominal pain and lesion size. To our knowledge, this is the first reported case of a pediatric MS patient with a demyelinating lesion associated with an autonomic symptom of altered intestinal mobility in the absence of neurological symptoms. This atypical presentation of MS highlights the need for physicians' vigilance when treating this patient population.

Abstract
INTRODUCTION In the chronic phase of Hemiconvulsion-Hemiplegia-Epilepsy (HHE) syndrome, developing epilepsy may be intractable. Herein, we report a case where adrenocorticotropic hormone (ACTH) ceased an intractable habitual partial seizure in a patient with HHE syndrome. CASE REPORT A developmentally normal one-year-old girl presented with left focal motor status epilepticus in the clinical course of rotavirus infection. She was diagnosed with HH syndrome. At 4 months after status epilepticus, she developed partial seizures that occurred daily, and which resulted in a stooped posture, head rotation to the right, and contraction of both upper limbs predominantly in the left arm. At this time, she was diagnosed with idiopathic HHE syndrome. Her seizures were not reduced by sodium valproate, clonazepam, clobazam, zonisamide, phenytoin, phenobarbital, topiramate, lamotrigine, or liposteroid. At the age of 7, ACTH therapy was performed. On the 10th day of ACTH therapy, the habitual seizure was ceased. However, partial seizures characterized by left arm contraction then developed. Treatment with 350 mg/day lamotrigine prevented this emerging seizure. She has been free of both seizure types for more than one year, with no serious adverse effects of ACTH therapy. CONCLUSION We suggest that ACTH therapy may be useful for patients with HHE, although further studies are required.

Abstract
BACKGROUND It is unclear whether the incidence of febrile seizure (FS) in children with Down syndrome (DS) is higher or lower than in the general population. In this study, we investigated the incidence of FS in DS patients using mailed questionnaires. METHODS The questionnaires were distributed to parents or caregivers of DS patients attending Osaka Medical College Hospital and six other facilities. The questionnaires were returned by mail from February 2012 to September 2013 from 323 families of DS patients (176 male, 147 female; age range, 3 months-47 years; median age, 5.0 years). To assess the incidence of FS in DS, we performed the following two analyses: (i) we calculated the incidence of FS among DS patients between the ages of 4 and 20 years (n = 199; 113 male, 86 female), and (ii) we extracted families with both DS and healthy siblings between the ages of 4 and 20 years (n = 150; 77 male, 73 female) and compared the incidence of FS in these sibling groups. RESULTS Five DS patients had a past history of FS. The incidence of FS in DS was 2.5%. The incidence of FS was significantly lower in DS patients compared with healthy siblings (P < 0.003; OR, 0.14). CONCLUSION The incidence of FS is lower in DS patients than in the general population.

Abstract
Acute virus-associated encephalopathy induces seizures. Serum N-terminal pro-B-type natriuretic peptide (NTproBNP) levels are elevated following febrile and afebrile seizures. However, the role of NTproBNP in acute virus-associated encephalopathy pathology is unknown. We enrolled 10 patients with acute virus-associated encephalopathy and convulsions (E group: 7 boys, 3 girls; median age, 3.10 ± 1.92 years) and 130 patients with febrile seizure (FS group: 80 boys, 50 girls; median age, 3.23 ± 2.44 years). The E group had significantly higher NTproBNP levels (345 ± 141 pg/mL) compared with the FS group (166 ± 228 pg/mL) (P < .0005). Furthermore, subjects with prolonged seizure within the E group had significantly higher NTproBNP levels (303 ± 107 pg/mL) compared with subjects with prolonged seizure within the FS group (134 ± 100 pg/mL) (P < .005). Our findings suggest that serum NTproBNP levels are increased during the acute phase of acute virus-associated encephalopathy associated with convulsion.

Abstract
Delirious behavior (DB) in children infected with influenza virus is an important symptom associated with encephalopathy. As children with influenza-associated DB with encephalopathy may require therapy whereas children with influenza-associated DB without encephalopathy do not, distinguishing between these conditions is essential. To clarify these differences and identify the most common features of acute encephalopathy, we retrospectively reviewed the clinical course, laboratory data, magnetic resonance imaging (MRI) and electroencephalography (EEG) findings, therapy, and prognosis of 48 children with influenza exhibiting DB. Of the 48 children, 37 and 11 were diagnosed with influenza A and B, respectively. Moreover, 40 were diagnosed with DB without encephalopathy (DBNE group) and 8, with DB with encephalopathy (DBE group). Reversible splenial lesion (RESLE) was detected in 7 patients in the DBNE group, mild encephalitis/encephalopathy with a reversible splenial lesion (MERS) in 2 patients, and a mild form of acute encephalopathy with biphasic seizures and late reduced diffusion in 1 patient in the DBE group. Serum sodium levels <136mEq/L were observed in 28 cases. Disturbance of consciousness was observed in 25 cases, seizure in 20, and slow waves on EEG in 22. Methylprednisolone pulse therapy was administered in 8 cases. No cases of neurological sequelae were observed. Although most of the clinico-radiological features of the DBNE and DBE groups did not differ substantially, marked differences were observed in the age at onset, initial neurological symptoms, duration of DB, rate of seizure, and slowing of background activity on EEG. These differences should be considered when distinguishing between DBNE and DBE in children.

Abstract
BACKGROUND IL-13, a helper T cell type 2 (Th2) cytokine, transforms cultured airway epithelial cells to goblet cells, and this is not inhibited by corticosteroids. IL-33 stimulates Th2 cytokines and is highly expressed in airways of persons with asthma. The effect of IL-33 on goblet cell differentiation and cytokine secretion has not been described. OBJECTIVE We examined the effect of IL-33 on CXCL8/IL-8 secretion from goblet or normally differentiated human bronchial epithelial (NHBE) cells and signalling pathways associated with IL-33 activation in these cells. METHODS Normal human bronchial epithelial cells were grown to goblet or normally differentiated ciliated cell phenotype at air-liquid interface in the presence or absence of IL-13. After 14 days, differentiated cells were exposed to IL-33 for 24 h. RESULTS CXCL8/IL-8 secretion into the apical (air) side of the goblet cells was greater than from normally differentiated cells (P < 0.01), and IL-33 stimulated apical CXCL8/IL-8 release from goblet cells, but not from normally differentiated cells (P < 0.01). IL-33 increased ERK 1/2 phosphorylation in goblet cells (P < 0.05), and PD98059, a MAPK/ERK kinase inhibitor, attenuated IL-33-stimulated CXCL8/IL-8 secretion from goblet cells (P < 0.001). IL-13 induced ST2 mRNA (P < 0.02) and membrane-bound ST2 protein expression on the apical side surface of goblet cells compared with normally differentiated cells, and neutralization with anti-ST2R antibody attenuated IL-33-induced apical CXCL8/IL-8 secretion from goblet cells (P < 0.02). CONCLUSIONS AND CLINICAL RELEVANCE Goblet cells secrete CXCL8/IL-8, and this is increased by IL-33 through ST2R-ERK pathway, suggesting a mechanism for enhanced airway inflammation in the asthmatic airway with goblet cell metaplasia.

Abstract
We report a 17-year-old female with juvenile neuronal ceroid-lipofuscinosis (NCL) accompanied by hypertrophic cardiomyopathy (HCM) and left ventricular noncompaction (LVNC). Within our knowledge, this is the first reported case of juvenile NCL with LVNC, and the youngest case of HCM diagnosed by ultrasound. Juvenile NCL is a progressive hereditary disease involving multi-organ accumulation of ceroid-lipofuscin; its resulting complications require prompt attention. Due to its relative rarity, its cardiac involvement is not well known. Based on findings from this patient and related juvenile NCL cases, the risk of cardiac involvement tends to increase with age; a high frequency of ventricular hypertrophy has been reported in patients aged older than 20 years of age. Medical progress and comprehensive care have led to longer survival in patients with juvenile NCL, which likely increases the incidence of cardiac involvement. In relation to HCM in other metabolic disorders, attention should be paid to arrhythmias, including repolarization disturbances, sinus node dysfunction and ventricular tachycardia. LVNC is a cardiomyopathy characterized by prominent left ventricular trabeculae and deep intratrabecular recesses, which are associated with diastolic or systolic dysfunction, thromboembolic complications and arrhythmias. From ours and other case reports, we recommend regular follow-up of NCL patients as follows: echocardiography to estimate cardiomyopathy, Holter monitoring to identify arrhythmias, and computed tomography to detect thrombosis from both ventricles. The mechanism of the HCM and LVNC associated with juvenile NCL remains unclear. Our case requires careful follow-up. Prospective studies of the cardiac involvement in juvenile NCL are necessary to further elucidate its pathomechanism.

Abstract
A simple method was developed to establish serum-independent Chinese hamster ovary (CHO) cells that grew and secreted high level of human antithrombin-III (AT-III). First, human AT-III and mouse dihydrofolate reductase (DHFR) cDNAs were transfected into DHFR-deficient CHO cells. Transfected cells were treated with increasing concentrations of methotrexate (MTX) and clones secreting high levels of AT-III (10-20 micrograms/ml/3 day) in a serum-containing medium were obtained. Serum-independent clones were derived from the serum-dependent clones by simply culturing the cells for a few weeks in a serum-free medium. In a serum-free medium the established serum-independent clones grew at normal rate and produced almost equivalent amount of AT-III to that of the serum-dependent, parent clones. In addition, AT-III from the serum-independent clones has specific activity similar to that of plasma-derived AT-III.

Abstract
BACKGROUND Children with early adiposity rebound (AR), measured using individual body mass index (BMI) growth curves, have an increased risk of metabolic disease as adults. The children with early AR, however, are not fully characterized. The aim of this study was to investigate the prevalence and characteristics of the infants who develop early AR. METHODS A total of 1248 full-term children and their mothers participated in the present study. Pre-pregnancy, prenatal, birth, 4 month and 18 month records were collected. Children were classified into two groups: a decrease (D) group, in which the 18 month BMI was lower than the 4 month BMI (n = 1097), in keeping with the standard BMI percentile curve, and an increase (I) group, in which the 18 month BMI was higher than the 4 month BMI (n = 151). RESULTS Although children in both groups had similar body size at birth, those in the I group had a lower weight at 4 months and higher weight at 18 months than those in the D group (P < 0.001). Fewer mothers in the I group exclusively breast-fed their infants (P = 0.012). These characteristics of infants in the I group suggested a pattern of low fatness level followed by rapid increased fat gain. CONCLUSIONS Approximately 10% (151/1248) of infants did not follow the standard BMI percentile curves between 4 months and 18 months of age. They were more likely not to be exclusively breast-fed. This finding further stresses the importance of breast-feeding in early infancy.

Abstract
Recently, many cases of children presenting reversible splenial lesions during febrile illness (RESLEF) have been reported; however, their overall clinico-radiological features are unclear. To describe the clinico-radiological features, we retrospectively reviewed the etiology (pathogen), clinical course, laboratory data, magnetic resonance imaging and electroencephalography (EEG) findings, therapy, and prognosis of 23 episodes in 22 children (1 child recurred) who presented neurological symptoms, with RESLEF. The etiologies (pathogens) varied. Seizure occurred in 7 episodes, disturbance of consciousness (DC) in 13, and delirious behavior in 18. Serum sodium levels <136 mEq/L were observed in 18 episodes. Lesions outside the splenium were found in 4 cases. Slow waves were observed on EEG in 10 episodes. Methylprednisolone pulse therapy was given in 7 cases. No case resulted in neurological sequelae. Among 23 episodes, clinically mild encephalitis/encephalopathy with a reversible splenial lesion (MERS) was diagnosed in 6 episodes, whereas non-MERS was observed in 17 episodes. No difference was observed in almost all the clinico-radiological features' data between the 2 groups. The largest differences were observed in the rate of purposeless movement, DC, extension of the abnormal lesions outside the splenium, and marked slowing of background activity on EEG. RESLEF exhibit a spectrum of clinico-radiological features. These results suggest that non-MERS and MERS both are a part of a larger pathological condition, which we have termed as RESLEF spectrum syndrome. Given the view that such a syndrome exists, the clinical characteristics and position of non-MERS and MERS become clear.
