Background: Obesity in childhood and adolescence remains a great global health challenge. Stress exposure during childhood and adolescence is associated with a higher risk for obesity, yet the linkage between stress and obesity is multidimensional, and its biological and behavioral mechanisms are still not fully understood. Summary: In this literature review, we identified different types of stress exposure in children and adolescents, including first studied effects of the COVID-19 pandemic as a prolonged stress exposure and their association with obesity risk. We investigated studies on the connection of altered stress biology and behavioral pathways as well as intervention programs on stress reduction in children and adolescents with obesity. Key Messages: There is evidence that stress exposure in childhood and adolescence promotes biological and behavioral alterations that contribute to the multifactorial pathogenesis of obesity. COVID-19 related-stress presents the most current example of a negative influence on weight development in children and adolescents. However, longitudinal studies on the linkage between environmental, behavioral, and biological factors across development are few, and results are partly equivocal. Intervention programs to reduce stress in children through mindfulness might be a promising adjunctive tool in the prevention and treatment of childhood and adolescent obesity that could further offer proof of concept of theoretically elaborated cause-and-effect relationships.

Introduction Although intrathecal baclofen (ITB) therapy is an effective treatment for spasticity, it has several disadvantages and a risk of complications. Methods We present six pediatric patients who suffered from unusual mechanical failures of intrathecal baclofen pump systems. Results With these case-vignettes, we provide a systematic approach on how to interpret the symptoms of ITB complications and an advice which further diagnostic and therapeutic steps to follow. We underline the seriousness of baclofen overdose, underdosing or withdrawal.

Background Quantitative mapping of MRI relaxation times is expected to uncover pathological processes in the brain more subtly than standard MRI techniques with weighted contrasts. So far, however, most mapping techniques suffer from a long measuring time, low spatial resolution or even sensitivity to magnetic field inhomogeneity. Objective To obtain T1 relaxation times of the normal brain from early infancy to adulthood using a novel technique for fast and accurate T1 mapping at high spatial resolution. Materials and methods We performed whole-brain T1 mapping within less than 3 min in 100 patients between 2 months and 18 years of age with normal brain at a field strength of 3 T. We analyzed T1 relaxation times in several gray-matter nuclei and white matter. Subsequently, we derived regression equations for mean value and confidence interval. Results T1 relaxation times of the pediatric brain rapidly decrease in all regions within the first 3 years of age, followed by a significantly weaker decrease until adulthood. These characteristics are more pronounced in white matter than in deep gray matter. Conclusion Regardless of age, quantitative T1 mapping of the pediatric brain is feasible in clinical practice. Normal age-dependent values should contribute to improved discrimination of subtle intracerebral alterations.

Even though shunt surgery has been an established and widely accepted treatment for congenital hydrocephalus for five decades, long-term follow-up and functional outcome data are scarce. Based on our experience, we advocate a very rigid follow-up regimen throughout life for every hydrocephalus patient encountered with individual screening intervals not longer than 1 year in childhood and adolescence and surveillance intervals of 2 years in adulthood. A continuous treatment of the patients at the primary institution that performed hydrocephalus surgery provides an optimal setting to be prepared for the detection of adverse events of shunt malfunctioning. However, some patients may still encounter catastrophic events resulting in persistent deficits or death.

Moyamoya disease (MMD) is characterized by bilateral, chronic progressive stenosis at the terminal portions of the internal carotid arteries and their proximal branches. The “smoke-like” appearance of the arterial collaterals in angiography gives the disease its name. The “ivy-sign” is the less-known magnetic resonance imaging (MRI) pattern of this disease. The leptomeningeal collaterals present as diffuse signal enhancement at the brain surface in contrast-enhanced T1-weighted image and fluid-attenuated inversion recovery sequences “as if overgrown with ivy.”We report on three patients with MMD in whom the “ivy-sign” was already present but misinterpreted in the initial MRI of the brain. The correct diagnosis was made only after repeated MRI.Using three case studies, we describe the difficulties in the interpretation of the “ivy-sign” as an MRI pattern. Knowledge of the “ivy-sign” can be helpful, especially in diseases predisposing to MMD. If this MRI pattern is present, MMD should be considered and MR angiography should be added.

Objective The main purpose of this article is to demonstrate the co-occurrence of Axenfeld-Rieger anomaly and neuropsychiatric problems as clinical signs of genetically determined cerebral small vessel disease in two patients. Case Study We report on two adolescent individuals with ocular anterior segment dysgenesis (Axenfeld-Rieger anomaly) presenting with neuropsychiatric symptoms. Both patients underwent cerebral magnetic resonance imaging showing white matter T2-hyperintensities involving different brain regions, suspective of cerebral small vessel disease. Genetic analysis revealed pathogenic mutations in the FOXC1 gene (patient 1) and the COL4A1 gene (patient 2), respectively. Conclusion We report on the co-occurrence of ocular anterior segment dysgenesis (Axenfeld-Rieger anomaly) and neuropsychiatric symptoms as clinical signs of genetically determined cerebral small vessel disease in two patients. In both patients, the cerebral lesions involved the frontotemporal regions, brain regions that control social behavior as well as executive and cognitive function, highlighting the fact that neuropsychiatric symptoms may be early clinical presentations of cerebral small vessel disease. We further provide a review of monogenic causes of pediatric cerebral small vessel disease, emphasizing the links to childhood-onset neuropsychiatric disease.

ZUSAMMENFASSUNGEin Status epilepticus stellt einen Notfall dar, der mit einer erheblichen Morbidität und Mortalität einhergeht. Aus operationaler Sicht wird daher mittlerweile ein Status epilepticus in der Erwachsenenneurologie ab einer Anfallsdauer von 5 Minuten definiert. Der Notfalltherapie sowohl im Laien- als auch im Klinikbereich kommt eine sehr wichtige Rolle zu. Therapie der ersten Wahl sind weiterhin Benzodiazepine. Zunehmend positive Erfahrungen und Studienergebnisse liegen für Valproat, Levetiracetam und Lacosamid auch für pädiatrische Patienten vor.

ZUSAMMENFASSUNGNusinersen (Spinraza® ) ist das einzige bislang zugelassene Medikament zur Therapie der spinalen Muskelatrophien (SMA). In der EU besteht die Zulassung als Orphan Drug seit Anfang 2016 und gilt für alle Formen der spinalen Muskelatrophien. Dieser Artikel gibt einen Überblick über Wirkmechanismus und Anwendung des Medikaments sowie erste klinische Erfahrungswerte nach 3 Jahren der Behandlung von Patienten mit SMA an der Universitätsklinik für Kinder- und Jugendmedizin Leipzig.

TUBA1A tubulinopathy is a rare neurodevelopmental disorder associated with brain malformations as well as early-onset and intractable epilepsy. As pathomechanisms and genotype-phenotype correlations are not completely understood, we aimed to provide further insights into the phenotypic and genetic spectrum. We here present a multicenter case series of ten unrelated individuals from four European countries using systematic MRI re-evaluation, protein structure analysis, and prediction score modeling. In two cases, pregnancy was terminated due to brain malformations. Amongst the eight living individuals, the phenotypic range showed various severity. Global developmental delay and severe motor impairment with tetraparesis was present in 63% and 50% of the subjects, respectively. Epilepsy was observed in 75% of the cases, which showed infantile onset in 83% and a refractory course in 50%. One individual presented a novel TUBA1A-associated electroclinical phenotype with evolvement from early myoclonic encephalopathy to continuous spike-and-wave during sleep. Neuroradiological features comprised a heterogeneous spectrum of cortical and extracortical malformations including rare findings such as cobblestone lissencephaly and subcortical band heterotopia. Two individuals developed hydrocephalus with subsequent posterior infarction. We report four novel and five previously published TUBA1A missense variants whose resulting amino acid substitutions likely affect longitudinal, lateral, and motor protein interactions as well as GTP binding. Assessment of pathogenic and benign variant distributions in synopsis with prediction scores revealed sections of variant enrichment and intolerance to missense variation. We here extend the clinical, neuroradiological, and genetic spectrum of TUBA1A tubulinopathy and provide insights into residue-specific pathomechanisms and genotype-phenotype correlations.

Pathogenic variants in PRRT2, encoding the proline-rich transmembrane protein 2, have been associated with an evolving spectrum of paroxysmal neurologic disorders. Based on a cohort of children with PRRT2-related infantile epilepsy, this study aimed at delineating the broad clinical spectrum of PRRT2-associated phenotypes in these children and their relatives. Only a few recent larger cohort studies are on record and findings from single reports were not confirmed so far. We collected detailed genetic and phenotypic data of 40 previously unreported patients from 36 families. All patients had benign infantile epilepsy and harbored pathogenic variants in PRRT2 (core cohort). Clinical data of 62 family members were included, comprising a cohort of 102 individuals (extended cohort) with PRRT2-associated neurological disease. Additional phenotypes in the cohort of patients with benign sporadic and familial infantile epilepsy consist of movement disorders with paroxysmal kinesigenic dyskinesia in six patients, infantile-onset movement disorders in 2 of 40 individuals, and episodic ataxia after mild head trauma in one girl with bi-allelic variants in PRRT2. The same girl displayed a focal cortical dysplasia upon brain imaging. Familial hemiplegic migraine and migraine with aura were reported in nine families. A single individual developed epilepsy with continuous spikes and waves during sleep. In addition to known variants, we report the novel variant c.843G&gt, T, p.(Trp281Cys) that co-segregated with benign infantile epilepsy and migraine in one family. Our study highlights the variability of clinical presentations of patients harboring pathogenic PRRT2 variants and expands the associated phenotypic spectrum.

Background A rare symptom of Glut1 deficiency syndrome (Glut1 DS) is hemiplegic migraine (HM). Case We report a patient with Glut1 DS with a mild phenotype. His leading symptom was HM. As an unusual complication of the initiation of a ketogenic diet (KD), our patient developed paroxysmal nonkinesigenic dyskinesia. Paroxysmal dyskinesia occurred first and exclusively at the initiation of KD. Literature review There are a few case reports for HM in Glut1 DS. All patients had additional neurological symptoms. Regarding central nervous system symptoms such as paroxysmal dyskinesia triggered by KD, we found only 1 other case report. Discussion HM is part of the symptom complex of Glut1 DS and can be effectively treated by KD. Paroxysmal dyskinesia trigged by the initiation of KD should not lead to the discontinuation of the diet in Glut1 DS.

Bilateral optic neuritis (bilON) is a rare clinical presentation often thought to be associated with relapsing disorders such as neuromyelitis optica spectrum disorders (NMOSD) or multiple sclerosis (MS).To characterize the clinical, radiological phenotype and antibody status of children presenting with bilON.Retrospective multicenter study on children with bilON age18 years with a first episode aquired demyelinating syndrome (ADS), cMRI, AQP4- and serum MOG-antibody status and follow-up data were collected.30 patients (f:m = 15:15, median age 8.0y) with bilON met the inclusion criteria. 22/30 (73%) were MOG-positive (median: 1:1280, range: 1:160-1:1520). No patient showed AQP4-abs. 4/30 patients (13%), all with high MOG-abs titers, had recurrent episodes. No patient developed MS. Improvement after IVMP was observed in most patients (26/30; 87%). Outcome was favorable with no sequelae in 22/30 patients. Serial MOG-abs titers tested in 15/22 patients decreased to a median of 1:160 (range: 0-1:640) over a period of 31 months (range: 2-141 months) in 14/15 (93%) patients. MR imaging showed a predominantly anterior affection of the visual system in seropositive patients with bilateral intraorbital lesions in 68% (15/22), compared to 25% in MOG-negative patients (2/8).Pediatric bilON is associated with high MOG-abs titers in combination with anterior involvement of the visual system. Despite severe loss of vision, the majority of patients shows distinct recovery after IVMP.

Polytrauma in children is rare but potentially life-threatening. At the site of the accident the physician has to stabilize respiration and circulation to achieve normoxia and normotonia. The Glasgow Coma Scale allows for assessment of the severity of the trauma and for an estimate of the prognosis. Accompanying lesions such as internal bleeding, spine fractures or peripheral nerve lesions have to be assessed. The patient will be transferred to a pediatric intensive care unit in a hospital with neurosurgical facilities. After eventual (neuro)surgical interventions, cerebral perfusion pressure has to be monitored and maintained. Early start of physiotherapy and supportive care involving parents and families enables a successful rehabilitation.

Objective Parents of children with epilepsy are at risk of committing high-risk handling errors with a high potential to harm the patient when administering anticonvulsant rescue medication. We developed a training concept addressing identified high-risk handling errors and investigated its effects on parents' skills. Study design In a controlled prospective intervention study, parents of children with epilepsy were asked to demonstrate their administration of rescue medication by using dummy dolls. A clinical pharmacist monitored rectal or buccal administration and addressed errors in the intervention group with training and information sheets. Three to 6 weeks later, intervention's sustainability was assessed at a home visit. Results One hundred sixty-one parents completed full study assessment: 92 in the intervention group and 69 in the control group. The number of processes with at least one handling error was reduced from 96.4% to 56.7% in rectal tube administration and from 66.7% to 13.5% in buccal administration (both p Conclusion A one-time intervention for parents significantly and sustainably reduced high-risk handling errors. Dummy dolls and information sheet were adequate for an effective and feasible training to support the correct administration of anticonvulsant rescue medication.

A developmental disorder of a child has a major impact on the affected families' lives. However, data about the parents' perception of the revealing of the diagnosis is scarce.Parents of children with developmental disorder treated as outpatients in a university hospital were interviewed about the initial medical consultation concerning the diagnosis of their child.Parents of 210 children agreed to take part in the study. 35/210 (17%) had to be excluded from the study as they were not able to remember the initial medical consultation, or claimed there was either no initial medical consultation or they did not attend it. The diagnosis of developmental disorder was made in median 4 months (Q25/Q75: 0/12; min/max: 0/63) after the parents had noticed the first symptoms. According to the parents, options to support the development of the child were the most frequently addressed topic in the initial medical consultation (119/175, 68%). Some parents wished more empathy (19/175, 11%), and less medical terminology (12/175, 7%). 114/175 (65%) of parents rated the initial medical consultation as "very good" or "good". After their initial medical consultation, 66/175 (38%) of the parents had open questions mainly concerning the prognosis of the disease. Sources of information that were used after the consultation were most often the treating physician (150/175, 86%) and the internet (133/175, 76%).Generally, parents perceive the initial medical consultation on the developmental disorder of their child well. Nevertheless, many parents state that they had unanswered questions after the consultation. The internet is one of the main sources parents use to answer those questions.Die Entwicklungsverzögerung eines Kindes hat einen erheblichen Einfluss auf das Leben betroffener Familien. Es gibt jedoch kaum Daten darüber, wie Eltern die Diagnoseeröffnung erleben.Eltern, deren Kinder ambulant in einer Universitätsklinik behandelt wurden, wurden zum ärztlichen Erstgespräch zur Diagnose ihres Kindes befragt.Eltern von 210 Kindern stimmten der Teilnahme zu. 35/210 (17%) mussten ausgeschlossen werden, weil sie sich entweder nicht an das Erstgespräch erinnern konnten oder angaben, dass ein solches Gespräch nie stattgefunden habe oder sie nicht daran teilgenommen haben. Die Diagnose Entwicklungsverzögerung wurde im Median 4 Monate (Q25/Q75: 0/12; min/max: 0/63), nachdem die Eltern die ersten Symptome beobachtet hatten, gestellt. Laut Eltern wurden im Erstgespräch insbesondere Unterstützungsmöglichkeiten für die Entwicklung des Kindes besprochen (119/175, 68%). Einige Eltern wünschten sich mehr Empathie (19/175, 11%) und weniger medizinische Fachausdrücke (12/175, 7%). 114/175 (65%) der Eltern bewerteten das Gespräch als „sehr gut“ oder „gut“. Nach dem Erstgespräch hatten 66/175 (38%) der Eltern offene Fragen, insbesondere bezüglich der Prognose der Erkrankung. Als Hauptinformationsquellen nach dem Erstgespräch dienten der behandelnde Arzt (150/175, 86%) und das Internet (133/175, 76%).Im Allgemeinen empfinden Eltern das Erstgespräch zur Entwicklungsverzögerung ihres Kindes positiv. Dennoch geben viele Eltern an, dass sie nach dem Erstgespräch offene Fragen hatten. Das Internet ist eine der Hauptinformationsquellen, die Eltern zur Beantwortung dieser Fragen nutzen.

ZusammenfassungFür die Diagnostik von Epilepsien im Kindes- und Jugendalter und deren Behandlung mit Antikonvulsiva ist Expertise in unterschiedlichen Bereichen nötig. Der Patient profitiert dabei vom Zusammenwirken verschiedener Berufsgruppen. Risiken müssen reduziert und die in klinischen Studien gezeigte Wirksamkeit auch in eine möglichst gute Effektivität unter Routinebedingungen umgesetzt werden. Dabei sollten zunächst Aspekte der Arzneimittelverschreibung durch den Arzt berücksichtigt werden, wie etwa die Auswahl, Kombination und Dosierung der Antikonvulsiva. Dabei sollte die Arzneimittelanwendung nicht vergessen werden. Erst, wenn ein Antikonvulsivum richtig angewendet wird, kann der vom verordnenden Arzt gewünschte Therapieerfolg auch erreicht werden. Dabei sollten sich Maßnahmen nicht nur auf den Pflegedienst, sondern auch auf die Eltern, die Kinder und Jugendlichen selbst sowie Betreuer in Schulen und Kindertageseinrichtungen erstrecken. Durch theoretische Schulungen, praktische Übungen und regelmäßige Einbindung von Apothekern ins interdisziplinäre Behandlungsteam wird vermeidbaren arzneimittelbezogenen Problemen, die zu mangelnder Effektivität und dem Auftreten erhöhter Risiken führen können, vorgebeugt. Auf diese Weise wird nicht nur die Arzneimittel(therapie)sicherheit qualitativ verbessert, sondern auch die Teilhabe und Lebensqualität der Patienten und deren Familien positiv beeinflusst.

Purpose Attitudes concerning epilepsy improved over the last few decades, but children with epilepsy still suffer from stigmatisation. Data about unaffected children's knowledge of and attitudes about epilepsy is scarce. Methods We developed a questionnaire regarding epilepsy for high school students attending 8th–10th grade. The survey was performed from October 2015 to March 2016 in 5 different federal states of Germany. Results 1092 students [mean age (Q25/75): 14.5 (14/15) years] participated. 542/1092 (50%) of the respondents knew that people could die from a seizure. 216/1092 (20%) thought emotional strain could cause epilepsy. Asked for measures they would perform in case of a seizure, 235/1092 (24%) participants would hold the person to the ground, and 182/1092 (19%) would put a solid object into the person's mouth. 28/1092 (3%) would not like to be friends with a person with epilepsy, and 237/1092 (22%) would not like to go on a date with a person with epilepsy. Answers of 342/1092 (31%) students of a school located nearby a specialised epilepsy centre differed in some questions. The latter students were more familiar with epilepsy and showed better knowledge concerning causes, symptoms and treatment of epilepsy. In a question about special characteristics of people with epilepsy, 63/342 (18%) [other schools: 52/750 (11%)] answered people with epilepsy were friendlier and 76/342 (22%) [other schools: 49/750 (11%)] answered they were more sociable compared to people without epilepsy. Conclusion To improve knowledge and attitudes and reduce misconceptions further education seems necessary.

Zusammenfassung Hintergrund Myelin-Oligodendrozyten-Glykoprotein (MOG) ist an der Oberfläche der Myelinscheiden und der Oligodendrozyten im Zentralnervensystem lokalisiert. Im Kindes- und Erwachsenenalter zeigt sich eine Assoziation von MOG-AK im Serum mit rezidivierender und bilateraler Neuritis nervi optici (NNO), mit akuter disseminierter Enzephalitis (ADEM) und mit transverser Myelitis (TM). Die Kombination von NNO mit TM oder anderen entzündlichen Hirnläsionen ist typisch für eine Neuromyelitis-optica-Spektrum-Erkrankung (NMO-SD), die mit hochspezifischen pathogenen Aquaporin-4-IgG-Autoantikörpern (AQP4-AK) im Serum assoziiert ist. Kinder mit NMO-SD sind häufig seronegativ für AQP4-AK, aber seropositiv für MOG-AK. Krankheitsverlauf und Therapie der NNO bei Kindern mit NNO-positiven MOG-AK sind deshalb von besonderem Interesse. Patienten Die Krankheitsverläufe von 2 8-jährigen Jungen mit akuter NNO werden dargestellt (bilaterale NNO, AQP4-AK negativ, MOG-AK positiv). Patient 1 erlitt trotz immunsuppressiver Therapie mehrere Rezidive bei persistierenden MOG-AK mit zunehmender Optikusatrophie, erheblicher einseitiger Visusminderung und passagerer Hirnstammbeteiligung. Bei Patient 2 liegt ein bisher monophasischer Verlauf mit raschem Abfall der MOG-AK und nur geringer asymmetrischer Optikusatrophie vor. Diskussion MOG-AK sind im Kindesalter mit rezidivierender NNO und Hirnläsionen assoziiert, die typisch für eine ADEM oder eine NMO-SD sind. In der akuten Phase der klinischen Symptomatik werden hohe MOG-AK-Titer beobachtet. Rezidive der NNO führen zu einem zunehmenden Verlust der retinalen Nervenfaserschicht. Diagnostisch sind die Antikörperbestimmung (AQP4-AK, MOG-AK) sowie eine MRT-Bildgebung obligat. Als therapeutische Schlussfolgerung ergibt sich daraus die Notwendigkeit einer konsequenten Behandlung mit initial Kortikosteroiden und nachfolgender Immunsuppression (z. B. Azathioprin, Mycophenolat, bei refraktären Fällen auch Rituximab) sowie der Kontrolle der MOG-AK-Titer.

Prolonged seizures can cause severe harm and even death. For seizures lasting longer than 5min, an administration of rescue medication is therefore recommended. Caregivers such as preschool teachers should be able to administer correctly anticonvulsive rescue medication to children.A training concept for preschool teachers on seizure management focussing on practical skills was developed. To assess the success of the training, a structured interview on attitudes relating to rescue medication administration was conducted. The number of committed errors during administration of a rectal/buccal rescue medication to dummy dolls was compared before and after training.210 teachers from 115 preschools participated while all teachers from 303 preschools had been invited. The self-reported level of confidence in their own skills to administer anticonvulsive rescue medication increased from 5 to 8 on a scale from 1 to 10 (p0.001). The number of participants who agreed to administer rescue medication rose from 195/210 (92.8%) before training to 209/210 (99.5%, p0.001) after training for the rectal route, and from 173/210 (82.4%) to 209/210 (99.5%, p0.001) for the buccal route. For teachers who administered rescue medication before and after training, the number of administrations without any administration errors rose from 1/195 (0.5%) to 117/195 (60.0%, p0.001) for the rectal route, and from 13/173 (7.5%) to 95/173 (54.9%, p0.001) for the buccal route.A training for preschool teachers boosted the level of self-confidence relating to administration of anticonvulsive rescue medication. Teachers also committed fewer errors when administering rescue medication to dummy dolls.

Seizure disorder and developmental disorder are two of the most common chronic disorders in childhood. Data on perceived parental burden and specific effects on daily life is scarce. We performed a structured interview, consecutively talking to all parents of pediatric outpatients of our university hospital diagnosed with seizure or developmental disorder. Three hundred seven parents (of 317 affected children: 53 with seizure disorder, 44 with specific developmental disorder, 35 with learning disorder, 71 with intellectual disability, 15 with seizure + specific developmental disorder, 23 with seizure + learning disorder, 76 with seizure disorder + intellectual disability) were interviewed. Parents of children with both seizure disorder and intellectual disability stated the highest constraints in daily life, regarding friends, hobbies, emotional pressure, occupation, partnership, habitation, and financial burden. Due to diagnosis of seizure or developmental disorder, 155/307 (51%) parents reduced their working hours/stopped working, 62/307 (20%) changed their habitation, and 46/307 (15%) broke up. As judged by parents, 148/317 (47%) children are being discriminated against, even own family/friends and educators are held responsible.Parents perceive changes in their daily life and discrimination of their children due to their children's seizure and developmental disorders. An intellectual disability combined with seizure disorder caused the highest constraint. What is Known: • Seizure and/or developmental disorders of children may adversely influence quality of life for affected parents. • Caring for a child with special health care needs can take complete attention and own parental needs may therefore be difficult to meet. What is New: • Two out of three parents stated changes of their daily life such as quitting work, change of habitation, or breakup of partnership due to their child's diagnosis. • As judged by the parents, one in two children with developmental disorder of any kind is being discriminated against, even teachers and own family are held responsible.

Introduction The ciliopathy "Joubert syndrome" was first described in 1969 by Dr. Marie Joubert and most subtypes follow an autosomal recessive inheritance. The complex disorder shows typical clinical features, such as hyperventilation, abnormal eye movements, and retardation. A pathognomonic midbrain-hindbrain malformation, the molar tooth sign, can be found on magnetic resonance imaging of the brainstem. There are a little more than 200 reports of Joubert syndrome in the literature. Case presentation We report a case of a 9-year-old boy who developed a progressive hydrocephalus starting from the age of 4. He underwent VP shunt placement at 8 years, which relieved hydrocephalus-related clinical symptoms and put development of the macrocephalus to a halt. Conclusion Neonatal hydrocephalus due to the altered anatomy of the posterior fossa has been reported earlier, but to our knowledge, this is the first case of a delayed onset of hydrocephalus in a patient with Joubert syndrome.

Background Accumulating evidence suggests a relationship between sleep alterations and overweight/obesity in children. Our aim was to investigate the association of sleep measures other than obstructive sleep apnea or sleep duration with overweight/obesity and metabolic function in children. Methods We conducted a prospective cohort study in school- aged children (aged 5 to 8 years, prepubertal, and 12 to 15 years, pubertal) with overweight/obesity and normal-weight children. All children underwent a standardized in-laboratory polysomnography followed by a fasting blood assessment for glucose and metabolic testing. Subjective sleep measures were investigated by a 7-day sleep diary and questionnaire. We analyzed prepubertal and pubertal groups separately using logistic regression and partial correlation analyses. Results A total of 151 participants were analyzed. Overweight/obese children had significantly higher odds for arousal index (prepubertal children: 1.28, Confidence interval (CI): 1.06, 1.67; pubertal children: 1.65, CI: 1.19, 2.29) than normal-weight children, independent of age and gender. In prepubertal children, arousal-index was positively associated with C-peptide (r=0.30, p=0.01), whereas Minimum O2 saturation was negatively associated with triglycerides (r=−0.34, p=0.005), adjusting for age and sex. However, associations were attenuated by further adjustment for body mass index standard deviation scores (BMI-SDS). In pubertal children, higher level of apnea-hypopnea-index and pCO2 predicted increased lipoprotein (a) levels (r=0.35, p=0.03 and r=0.40, p=0.01, respectively), independent of age, sex, and BMI-SDS. A negative association was found between pCO2 and high-density lipoprotein (HDL)-cholesterol (r=−0.40, p=0.01). Conclusions Overall, we report that sleep quality as measured by arousal index may be compromised by overweight and obesity in children and warrants attention in future intervention programs.

Metabolic myopathies are heterogeneous hereditary diseases affecting skeletal muscle energy supply. Symptoms usually comprise pain, cramps, hypotonia, weakness, and myoglobinuria.We present a boy with recurrent myalgia and weakness after some minutes of exercise or during febrile infections since early infancy. First laboratory workup at the age of 9 years showed no abnormalities, apart from a slightly elevated creatine kinase. After exclusion of common structural and metabolic myopathies, next generation sequencing panel (4 years after the initial diagnostic metabolic workup) revealed two potentially pathogenic missense mutations in the CPT2 gene (c.149C > A (p.P50H) and c.1459G > A (p.E487K)).Our case underscores the clinical variability of muscle carnitine palmitoyltransferase II (CPT II) deficiency and illustrates a pitfall of diagnostic algorithms for metabolic myopathies. Myalgia following exercise of a few minutes duration would have argued for a carbohydrate and against a fatty acid metabolic defect. However, CPT II deficiency is the most common disorder of muscle fatty acid metabolism and should be considered even in atypical scenarios. Analyses of plasma acyl carnitine profile during acute metabolic crises may help to unmask biochemical markers which are often overlooked in dried-blood analyses.

Introduction Beta-propeller protein-associated neurodegeneration (BPAN) is a very rare, X-linked dominant (XLD) inherited member of the neurodegeneration with brain iron accumulation (NBIA) disease family. Case report We present a female case of BPAN with infantile spasms in the first year, Rett-like symptomatology, focal epilepsy, and loss of motor skills in childhood. Menarche occurred at the age of 9, after precocious pubarche and puberty.Dystonia-parkinsonism as extrapyramidal sign at the age of 10 years resulted in radiological and genetic work-up. Results Burke–Fahn–Marsden Dystonia Rating Scale (BFMDRS) measured 66/120 points in body part-related dystonia symptoms. Cerebrospinal fluid examination showed dopamine depletion.T2 and B0 sequences of the diffusion-weighted magnetic resonance imaging showed susceptibility artifacts with NBIA-typical hypointense globus pallidus (GP) and substantia nigra (SN). Next-generation sequencing revealed a BPAN-causing pathogenic variant in WDR45 (WD repeat-containing protein 45) gene (c.830 + 1G > A, XLD, heterozygous, de novo). Skewed X-inactivation was measured (2:98). Conclusions Autophagy-related X-linked BPAN disease might still be underdiagnosed in female cases of infantile spasms.Skewed X-inactivation will have mainly influenced the uncommon, very early childhood neurodegenerative symptomatology in the present BPAN case. Oral levodopa substitution led to improvement in sleep disorder, hypersalivation, and swallowing.Reduced white matter and hypointense signals in SN and GP on susceptibility sequences in magnetic resonance imaging are characteristic radiological findings of advanced disease in NBIA. No BPAN-typical halo sign in T1-weighted scan at midbrain level was seen at the age of 11 years. NBIA panel is recommended for early diagnosis.

Harlequin syndrome (HS) is a rare dysautonomia of the sympathetic nervous system leading to asymmetric facial flushing and sweating. In the literature, only a few cases of HS after thoracoscopic tracheoesophageal fistula (TEF) repair are reported. We report on a newborn with TEF who developed HS after thoracoscopic repair. On the first day of life, the girl (3,480 g, gestation age: 41 week) underwent thoracoscopic repair of a type C esophageal atresia (TEF; OR time 105 minute) without complications. The postoperative course was uneventful, the patient swallowed and thrived well and did not require esophageal dilatations. At 2 years of age, missing facial flushing, transpiration, and warming on the right side of her face during agitation were noticed. As no further intervention was required, the girl and her parents adapted well to the symptoms. Our report shows that the late onset of HS after the surgical procedure is unlikely a direct causal relation to the thoracoscopic operation but rather a shared embryological pathogenesis, like a neurocristopathy.

ObjectiveThe study is aimed at widening the clinical and genetic spectrum and at assessing genotype-phenotype associations in QARS encephalopathy.MethodsThrough diagnostic gene panel screening in an epilepsy cohort, and recruiting through GeneMatcher and our international network, we collected 10 patients with biallelic QARS variants. In addition, we collected data on 12 patients described in the literature to further delineate the associated phenotype in a total cohort of 22 patients. Computer modeling was used to assess changes on protein folding.ResultsBiallelic pathogenic variants in QARS cause a triad of progressive microcephaly, moderate to severe developmental delay, and early-onset epilepsy. Microcephaly was present at birth in 65%, and in all patients at follow-up. Moderate (14%) or severe (73%) developmental delay was characteristic, with no achievement of sitting (85%), walking (86%), or talking (90%). Additional features included irritability (91%), hypertonia/spasticity (75%), hypotonia (83%), stereotypic movements (75%), and short stature (56%). Seventy-nine percent had pharmacoresistant epilepsy with mainly neonatal onset. Characteristic cranial MRI findings include early-onset progressive atrophy of cerebral cortex (89%) and cerebellum (61%), enlargement of ventricles (95%), and age-dependent delayed myelination (88%). A small subset of patients displayed a less severe phenotype.ConclusionsThese data revealed first genotype-phenotype associations and may serve for improved interpretation of new QARS variants and well-founded genetic counseling.

Objective Benign familial infantile seizures (BFIS), paroxysmal kinesigenic dyskinesia (PKD), and their combination—known as infantile convulsions and paroxysmal choreoathetosis (ICCA)—are related autosomal dominant diseases. PRRT2 (proline-rich transmembrane protein 2 gene) has been identified as the major gene in all 3 conditions, found to be mutated in 80 to 90% of familial and 30 to 35% of sporadic cases. Methods We searched for the genetic defect in PRRT2-negative, unrelated families with BFIS or ICCA using whole exome or targeted gene panel sequencing, and performed a detailed cliniconeurophysiological workup. Results In 3 families with a total of 16 affected members, we identified the same, cosegregating heterozygous missense mutation (c.4447G>A; p.E1483K) in SCN8A, encoding a voltage-gated sodium channel. A founder effect was excluded by linkage analysis. All individuals except 1 had normal cognitive and motor milestones, neuroimaging, and interictal neurological status. Fifteen affected members presented with afebrile focal or generalized tonic–clonic seizures during the first to second year of life; 5 of them experienced single unprovoked seizures later on. One patient had seizures only at school age. All patients stayed otherwise seizure-free, most without medication. Interictal electroencephalogram (EEG) was normal in all cases but 2. Five of 16 patients developed additional brief paroxysmal episodes in puberty, either dystonic/dyskinetic or “shivering” attacks, triggered by stretching, motor initiation, or emotional stimuli. In 1 case, we recorded typical PKD spells by video-EEG-polygraphy, documenting a cortical involvement. Interpretation Our study establishes SCN8A as a novel gene in which a recurrent mutation causes BFIS/ICCA, expanding the clinical–genetic spectrum of combined epileptic and dyskinetic syndromes.

Background The use of complementary and alternative medicine (CAM) is popular. Parents of children suffering from epilepsy may also consider administering CAM to their children. Systematic data about frequency of and motivations for CAM use, however, are scarce. Methods In a university hospital's neuropaediatric department parents of patients aged 0–18 years suffering from epilepsy were consecutively invited to take part in a structured interview during 4 months in 2014. Results Of the invited parents, 164/165 (99%) agreed to participate. From those, 21/164 (13%) stated that they used CAM in their child. The highest independent predictive value of CAM use was the occurrence of adverse drug events (ADE) of anticonvulsants as judged by parents. Patients affected by ADE had a 5.6 higher chance of receiving CAM compared to patients without ADE. Most commonly used were homeopathy (14/21, 67%) and osteopathy (12/21, 57%). The internet was the most frequently used source of information (14/21, 67%). Of the parents, 10/21 (48%) described positive effects of CAM on seizure frequency, 12/21 (57%) on general condition of their child, and 20/21 (95%) wished to continue CAM for epilepsy therapy. From the non-users of CAM, 91/143 (66%) expressed the desire to learn more about CAM for epilepsy therapy. Limitations Our study was performed in a university hospital in a large urban city in Eastern Germany. CAM user rates can differ in other parts of Germany and Europe, in other institutions and for chronic diseases other than epilepsy. Conclusion The main reason for CAM use was the occurrence of ADE of anticonvulsants. More than half of the parents saw a benefit of CAM for their children. Almost all parents wished to continue CAM use, even those who did not see concrete positive effects.

OBJECT Congenital hydrocephalus has a major impact on the lives of patients and their relatives, as well as their long-term neurological development and social integration. The aim of this study was to assess the self-reported health-related quality of life (HRQOL) of patients after reaching adulthood. METHODS A total of 31 patients who required CSF shunt treatment for congenital hydrocephalus within the 1st year of life (between 1963 and 1987) agreed to undergo a structured SF-36 self-assessment. An age-matched German standard cohort was used as control. Additional parameters of surgical, social, and global neurological outcome were analyzed. The mean patient age was 35 years (range 26–51 years, 13 females and 18 males). Hydrocephalus etiologies were posthemorrhagic hydrocephalus (n = 9), postinfectious hydrocephalus (n = 5), aqueductal stenosis (n = 10), myelomeningocele (n = 2), and unknown cause (n = 5). RESULTS The mean modified Rankin Scale score was 1.6 (range 0–4). Hydrocephalic patients achieved lower scores for the SF-36 items physical functioning (70.5 vs 93.5, p < 0.05), physical role functioning (74.2 vs 88.3, p < 0.05), and general health perceptions (64.5 vs 72.3, p < 0.05). Emotional, social role functioning, and mental health items did not differ between the groups. Assessment of vitality and pain resulted in a trend to worse values. Whereas the Physical Component Summary score was lower (46.1 vs 54.3, p < 0.05), the Mental Component Summary score was not significantly different (50.2 vs 48.7, p = 0.3). There was neither a statistically significant difference between subgroups of different etiologies nor an association with the number of subsequent hydrocephalus-related surgeries. CONCLUSIONS Adult HRQOL for patients with congenital hydrocephalus appears to be similar to that for healthy con with regard to mental health and social functioning aspects. Physical impairment is a predominant factor of compro quality of life.

Epilepsy and bronchial asthma are frequent in adolescents. Data on adolescents' experiences with their disease and on their expectations for the future, however, is scarce. Patients of a university hospital aged 12 to 17 with epilepsy or bronchial asthma were interviewed based on a questionnaire. Forty-five patients with epilepsy and 47 with bronchial asthma were interviewed. Adolescents with epilepsy felt more impaired by their disease (median 2.5; Q25/Q75 0.75/3.0; 6-level Likert scales: 0 = not at all, 5 = very strong) than those with asthma (1.0; 0/3.0; p = 0.017). Seventy-nine patients (85.9%) had never used the Internet to gain information about their disease. Adolescents with epilepsy felt more limited in their career possibilities by their disease (2.0; 0/4.0) than those with asthma (0; 0/2.0; p = 0.001) and had a higher level of concern about passing their disease on to their children (3.0; 0/4.0) than their peers with asthma (1.5; 1.5/3.0; p = 0.016). Girls with epilepsy were more anxious (4.0; 0.5/5.0) than girls with asthma (0; 0/4.0) about complications of the disease regarding pregnancy (p = 0.019).As well adolescents with epilepsy as with asthma described limitations of their daily life and concerns about the future. What is Known: • Epilepsy and bronchial asthma are frequent chronic diseases in adolescents. • Those diseases can affect psychosocial development. What is New: • Adolescents with epilepsy and bronchial asthma described a high burden of their disease, and most adolescents had not used the Internet to inform themselves on their disease. • Especially adolescents with epilepsy fear limitations in their job possibilities, inheritance of their disease and complications in their prospective pregnancy.

Antibodies against the myelin oligodendrocyte glycoprotein (MOG-Ab) can be detected in various pediatric acquired demyelinating syndromes (ADS). Here, we analyze the spectrum of neuroradiologic findings in children with MOG-Ab and a first demyelinating event. The cerebral and spinal MRI of 69 children with different ADS was assessed in regard to the distribution and characteristics of lesions. Children with acute disseminated encephalomyelitis (n = 36) or neuromyelitis optica spectrum disorder (n = 5) presented an imaging pattern characterized predominantly by poorly demarcated lesions with a wide supra- and infratentorial distribution. Younger children also tended to have poorly defined and widespread lesions. The majority of patients with an isolated optic neuritis (n = 16) only presented small non-specific brain lesions or none at all. A longitudinally extensive transverse myelitis mainly affecting the cervical, and less often so the thoracic, lumbar, and conus regions, was detected in 31 children. The three children of our cohort who were then finally diagnosed with multiple sclerosis had at onset already demarcated white matter lesions as well as transverse myelitis. In conclusion, children with MOG seropositive ADS present disparate, yet characteristic imaging patterns. These patterns have been seen to correlate to the disease entity as well as to age of symptom onset.

Objective We performed a retrospective chart analysis in neonates routinely treated with levetiracetam (LEV) in a university setting. Patients and Methods We assessed clinical characteristics of the included neonates. Documented LEV doses and the duration of treatment were evaluated. To assess LEV effectiveness, we compared the need of any additional anticonvulsant as co- and rescue therapies before and following the initiation of LEV treatment. To assess LEV tolerance, we sought to identify documented adverse drug reactions resulting in a termination of LEV treatment. Results We analyzed a total of 72 neonates receiving LEV with a median gestational age at initiation of LEV treatment of 30 4/7 gestational weeks (min., 24 5/7 /max., 43 0/7 weeks). LEV was applied in target doses of 41.7 mg/kg/d (min., 14.4/max., 106.2 mg/kg/d). Patients received LEV treatment at hospital for a median of 28 days (min., 1/max., 195 days). Additional anticonvulsant therapy decreased a week after LEV treatment was initiated ( p = 0.008). We did not find any cases of terminated LEV treatment resulting from adverse drug reactions. Conclusion Long term use of high LEV doses is rather frequent in immature neonates. Our data indicate good effectiveness and a low risk of adverse drug reactions.

In pediatric patients, brain tumors have been estimated to be the cause for seizures in only 0.2-0.3% of cases, whereas seizures occurred in about 13% of pediatric brain tumor patients at presentation. This survey was conducted to analyze EEG findings in pediatric tumor patients over the past 14 years to evaluate the diagnostic value of preoperative EEG for diagnosis of brain tumors. Surface EEG was obtained in awake patients using the international 10- to 20-electrode placement in all pediatric patients with intracranial neoplasms between 2000 and 2013 at the University Hospital of Leipzig except for those who needed emergency operative treatment. One hundred forty-two pediatric patients with 80 infratentorial and 62 supratentorial tumors (WHO grades I-II: 91 patients; WHO grades III-IV: 46 patients). Symptomatic hydrocephalus was found in 37. Sensitivity and specificity of ophthalmologic examination for predicting hydrocephalus was 0.39 and 0.72. Preoperative EEG has been conducted in 116 patients, showing normal activity in 54 patients (47%). Out of 62 pathologic EEGs, 40 indicated correctly to the site of the lesion, 15 were pathologic despite of infratentorial location of the tumor. Nineteen patients had a history of seizures of which six had normal EEGs. Sensitivity for and specificity of EEG examination for symptomatic epilepsy was 0.68 and 0.7. Conclusion Preoperative routine EEG provides no additional value in the diagnostic algorithm of pediatric train tumors. The low specificity and sensitivity of EEG (even in patients with clinical seizures as primary symptom of a brain tumor) underline that EEG does not contribute to diagnosis and a normal EEG might even delay correct diagnosis.

Menkes disease, an inherited disorder of copper transport, shows a spectrum of different neuroradiological findings. Diffuse brain atrophy, deficient myelination, and subdural hematoma/hygroma were described. Anomalies of the cerebral arteries with elongation and tortuosity are known. We report the neuroradiological follow up of a patient suffering from Menkes disease confirmed by the identification of a deletion of ATP 7A gene. Ultrasound scanning at the age of two months demon- strated normal brain morphology. One month later, magnetic resonance imaging (MRI) showed vermian hypoplasia, brain atro- phy and retarded myelination. Marked widening of cerebral venous sinuses in conventional angiography and in magnetic resonance venography was detected and led to arterial cerebral angiography, which did not disclose an arteriovenous fistula. Despite parenteral copper therapy, on MRI follow up seven months later, extra-axial blood and hygroma were visible and the signs of cerebral atrophy and myelination deficit were more pronounced. In Menkes disease, neuroradiological anomalies can occur early and progress rapidly despite copper therapy. When evaluating magnetic resonance angiography results in neurode- generative diseases, Menkes disease should be suspected not just when cerebral arterial anomalies are demonstrated. Widening of the cerebral venous sinuses might be caused by secondary to brain atrophy or involvement of the vein walls.

ProblemSchool and preschool teachers play a key role in the care of children with epilepsy. Yet, data about their knowledge on epilepsy are scarce.MethodsAssessment of knowledge and attitudes towards epilepsy in teachers by conducting a questionnaire survey in Leipzig and Blankenburg, Germany, from August 2013 to January 2014.Results1243 questionnaires were completed by 302 school teachers, 883 preschool teachers, 56 students and two unclassified participants. Of the respondents, 140 (11%) stated to have already been actively involved in an epilepsy emergency situation, another 148 (12%) as observers. Only 214 (17%) of respondents felt sufficiently prepared for an emergency. A rescue medication had already been applied by 79 (6%) of respondents; only 186 respondents (15%) stated they would be willing to administer a prescribed rescue medication under any circumstances. In response to an open-ended question about the most common fatal outcomes of a seizure, status epilepticus and drowning were rarely mentioned. 233 (19%) of respondents assumed that epileptic seizures cannot result in death. 606 (49%) of respondents were concerned about the legal repercussions to an incorrect response to a seizure.129/403 (32%) of teachers with >20 years of professional experience claimed never to have had a child suffering from epilepsy in their care, even though the prevalence of childhood epilepsy indicates that they should. In total, 1066 (86%) respondents expressed a desire to gain more knowledge on epilepsy.ConclusionsTraining programmes for teachers should be established. Furthermore, a clear legal regulatory framework needs to be set up.

We retrospectively evaluated predictors of conversion to multiple sclerosis (MS) in 357 children with isolated optic neuritis (ON) as a first demyelinating event who had a median follow-up of 4.0 years. Multiple Cox proportional-hazards regressions revealed abnormal cranial magnet resonance imaging (cMRI; HR 5.94; 95% CI: 3.39-10.39; p

Pediatric tumors of the central nervous system composed of oligoid tumor cells showing diffuse leptomeningeal spread without a primary mass lesion seem to represent a novel tumor entity. The terms “diffuse leptomeningeal glioneural tumor” or—preferably—“disseminated oligodendroglial-like leptomeningeal tumor of childhood” (DOGLT) were proposed. Four patients were identified with clinico-neuropathologic findings compatible with DOGLT and a mean follow-up time of 54 months was determined. Seven different biopsies obtained from the four patients were histologically evaluated. Clinical course, diagnostic measures, histopathologic and radiologic features and treatment suggestions were recorded, on the basis of which diagnostic and therapeutic algorithm was proposed. Patients with DOGLT presented with hydrocephalus as first symptom, requiring neurosurgical therapy. Open arachnoid biopsy was necessary to confirm diagnosis. The oligoid cells in a desmoplastic or focally myxoid matrix showed OLIG2-, MAP2-, S-100 and rare HuC/HuD protein-immunopositivity. IDH1 (R132H)- and CD99-immunohistochemistry was negative in all patients. None of the evaluable biopsies of three patients showed chromosome 1p/19q deletion, neither as isolated nor combined allelic loss. Chemotherapy according to the SIOP-LGG 2004 standard induction and consolidation protocol resulted in complete response and partial response, respectively, in 50 % of the patients. However, after discontinuation of chemotherapy, two patients experienced tumor progression and one of them succumbed to the disease after 19 months. Radiological criteria as well as preliminary treatment results are presented after observation of four clinical cases. Prognosis and long-term clinical courses remain to be observed.

Fetofetal transfusion syndrome is a dreaded cause of morbidity and mortality in monochorionic pregnancies. We present two pairs of twins one of which we have followed for more than 6 years. The donors suffer from cerebral palsy, orofacial, and motor problems, and both are significantly smaller than their recipient twins. Interestingly, cranial MRI revealed medial frontal lobe polymicrogyria, ventriculomegaly, and decreased thickness in both parietal lobes in both donors. We suggest this as a possible feature of fetofetal transfusion syndrome. A minireview of the literature on neuroimaging and neurodevelopmental outcome in fetofetal transfusion syndrome is presented. While the close resemblance of the imaging features of both cases is likely incidental further study of a connection between migration and gyration disorders and fetofetal transfusion syndrome is warranted.

Brain imaging is the most common examination in pediatric magnetic resonance imaging (MRI), often combined with the use of a gadolinium-based contrast medium. The application of gadolinium-based contrast medium poses some risk. There is limited evidence of the benefits of contrast medium in pediatric brain imaging. To assess the diagnostic gain of contrast-enhanced sequences in brain MRI when the unenhanced sequences are normal. We retrospectively assessed 6,683 brain MR examinations using contrast medium in children younger than 16 years in the pediatric radiology department of the University Hospital Leipzig to determine whether contrast-enhanced sequences delivered additional, clinically relevant information to pre-contrast sequences. All examinations were executed using a 1.5-T or a 3-T system. In 8 of 3,003 (95% confidence interval 0.12–0.52%) unenhanced normal brain examinations, a relevant additional finding was detected when contrast medium was administered. Contrast enhancement led to a change in diagnosis in only one of these cases. Children with a normal pre-contrast brain MRI rarely benefit from contrast medium application. Comparing these results to the risks and disadvantages of a routine gadolinium application, there is substantiated numerical evidence for avoiding routine administration of gadolinium in a pre-contrast normal MRI examination.

Background The main source of knowledge on adverse drug events (ADE) are physicians' reports in controlled clinical trials. In contrast, little is known about the parents' perception of ADE of anticonvulsants their children receive. Methods After approval by the local ethics committee, we performed a survey in a neuropediatric outpatient clinic of a university hospital. Based on a structured questionnaire, we interviewed parents of children with current anticonvulsant treatment regarding (i) their fears about potential ADE, (ii) experienced ADE according to parents, and (iii) implications of ADE on the child's life. Results Parents of 150 patients took part in the interview. (i) 95 (63.3%) parents expressed fears concerning ADE, mostly liver injury/liver failure (33 [22%]). (ii) 129 (86%) parents reported experienced ADE, mostly sedation (65 [43.3%]) and abnormal behavior (54 [36%]). (iii) Parents reported substantial implications of ADE on the child's daily life for 84 (56%) children, and 63 (42%) parents expressed a negative impact on the child's development. Conclusion We recognized a great discrepancy between those ADE that were feared and those that were experienced. Parents feared life-threatening ADE and experienced less severe ADE that nevertheless have a negative impact on the child's daily life.

Background: After a first afebrile seizure, EEG in addition to cMRI is recommended for pediatric patients. Once indications requiring immediate treatment are excluded, it is of interest to determine if the results provide a prognostic tool for seizure relapses. Methods: Patients aged between 1 month and 18 years who had a first afebrile seizure between 2006 and 2008 were retrospectively studied and monitored for another 48 months. Results: Out of 248 patients, 62.5% had generalized and 36.3% focal seizures. 34.7% of the EEG results were pathological. 176 patients had a cMRI that showed in 23.3% probable epileptogenic lesions. 3 patients with benign cerebral tumours needed surgical therapy. In the following 48 months 29.4% of the children showed seizure relapses. There was a correlation between epileptic patterns in the EEG and further seizures (p=0.0001). However, the sensitivity of the EEG based diagnoses was 0.6, the specificity 0.78 and the positive predictive value 0.52. There was no correlation between epileptogenic lesions and the probability of seizure relapses. The sensitivity of the cMRI to this effect was 0.36, the specificity 0.74 and the positive predictive value 0.34. Discussion: The EEG is superior to cMRI for predicting seizure relapses. The percentage of noticeable cMRI findings is high but this has low therapeutic relevance and is assumed to largely represent "incidental findings". It is important to question the value of MRI investigations for sedated small children except in the case of emergencies. The key question is whether the cMRI should be deployed to diagnose epilepsy, the probability of seizure recurrences or to classify the entity of a most likely epilepsy.

Children with certain risk factors, such as comorbidities or severe obstructive sleep apnea syndrome (OSAS) are known to require extended postoperative monitoring after adenotonsillectomy. However, there are no recommendations available for diode-laser-assisted tonsillotomy. A retrospective chart review of 96 children who underwent diode-laser-assisted tonsillotomy (07/2011–06/2013) was performed. Data for general and sleep apnea history, power of the applied diode-laser (λ = 940 nm), anesthesia parameters, the presence of postoperative respiratory complications and postoperative healing were evaluated. After initially uncomplicated diode-laser-assisted tonsillotomy, an adjustment of post-anesthesia care was necessary in 16 of 96 patients due to respiratory failure. Respiratory complications were more frequent in younger children (3.1 vs. 4.0 years, p = 0.049, 95 % CI −1.7952 to −0.0048) and in children who suffered from nocturnal apneas (OR = 5.00, p

Aim In Germany, preschool teachers supervise children up to six years of age and are also responsible for supervising older pupils after school. This study explored the impact of a teaching session on epilepsy for teachers in charge of children from 1-10 years of age. Methods We evaluated the benefit of a teaching session offered to all preschool teachers in Leipzig, Germany, in 2014-2015, by asking them to complete the same questionnaire 12-24 months pre-intervention, and 12 months post-intervention. Results Both questionnaires were completed by 123 teachers. The number of teachers who felt they were prepared to handle an acute seizure rose from 36 (29%) pre-intervention to 65 (53%) post-intervention (p

The established standard of pharmacotherapy of the attention deficit hyperactivity disorder is methylphenidate, a drug with very few side effects. A 4-year-old boy with T cell acute lymphoblastic leukemia, and severe damage to the white matter induced by chemo- and radiotherapy was treated with methylphenidate in increasing doses due to marked attention deficit hyper- activity disorder. Liver enzymes, i.e. aspartate aminotransferase, alanine aminotransferase and gamma glutamyltranspeptidase, were slightly elevated prior to therapy. Three weeks into methylphenidate therapy, the patient suffered from recurrent vomiting. Liver enzymes were elevated with alanine aminotransferase at 1260 U/L, aspartate aminotransferase at 499 U/L and gamma glutamyltranspeptidase 284 U/L. Creatine kinase was elevated at 405 U/L, while bilirubin and renal function parameters were within normal levels. Following discontinuation of therapy, liver enzymes returned almost to normal levels within a week. Hepatotoxic reactions to methylphenidate are extremely rare. As methylphenidate inhibits the liver cytochrome P450 system, synergistic toxic effects are possible in theory. An elevated creatine kinase level would be possible within the framework of autoimmune reactions. Patients with increased risk (i.e. age below 6 years, hepatic stress due to prior pharmacotherapy) should be treated with methylphenidate, only under close clinical and laboratory monitoring.

BACKGROUND: Anticonvulsants require special consideration particularly at the interface from hospital to ambulatory care. PATIENTS AND METHOD: Observational study for 6 months with prospectively enrolled consecutive patients in a neuropediatric ward of a university hospital (age 0
