Context: Survival rates exceed 90% in Wilms' tumor (WT). Actinomycin-D (ACT-D) which is indispensable in the management of WT is associated with the development of sinusoidal obstruction syndrome (SOS), a potentially fatal complication. Aims: The aim is to study the presentation, management, and outcome of SOS complicating ACT-D administration in WT. Settings and Design: Retrospective file review conducted in a Pediatric Hematology-Oncology unit...

Ifosfamide (IFA) is a potent alkylating antitumoral agent but its use is limited by neurological side effects. IFA is a racemic mixture of two enantiomeric forms, R-IFA and S-IFA with a stereoselective metabolism by CYP3A4 and CYP2B6, leading either to bioactive or to toxic pathways. In 3 consecutive cases of pediatric patients who exhibited ifosfamide-induced encephalopathy (IIE), genotyping of clinically relevant single nucleotide polymorphisms associated with decreased CYP3A4 and CYP2B6 activities was performed...

Fetal Alcohol Spectrum Disorders (FASD) might be 10-15 times more prevalent among foster/adopted children compared to the general population; however, many of these children remain undiagnosed or misdiagnosed. The lack of confirmed prenatal alcohol exposure (PAE) may be a key barrier to diagnosis. Our sample included 681 patients evaluated for FASD, according to the University of Washington 4-Digit Diagnostic Code, at a pediatric specialty clinic. Guardianship status and other patient characteristics were evaluated by multinomial logistic regression as potential predictors of being classified into one of the following FASD groups: 1) full or partial Fetal Alcohol Syndrome (FAS/pFAS; n = 97); 2) Static Encephalopathy/Alcohol-Exposed (SE/AE) or Neurobehavioral Disorder/Alcohol-Exposed (ND/AE) (n = 135); and 3) some features of FASD (equivalent to pFAS, SE/AE or ND/AE phenotypes) but unknown PAE (n = 449)...

The hallmark of pediatric cerebral malaria (CM) is sequestration of parasitized red blood cells in the cerebral microvasculature. Malawi-based research using 0.35 Tesla (T) magnetic resonance imaging (MRI) established that severe brain swelling is associated with fatal CM, but swelling etiology remains unclear. Autopsy and clinical studies suggest several potential etiologies, but limitations of 0.35 T MRI precluded optimal investigations into swelling pathophysiology. A 1.5 T MRI in Zambia allowed for further investigations including susceptibility-weighted imaging (SWI)...

Antibody-mediated encephalopathies associated with serum or cerebrospinal fluid antibodies directed against neuronal structures may present with a multitude of neuropsychiatric syndromes. Although some of the antibody-driven conditions are now well recognized in adults (eg, N-methyl-D-aspartate receptor antibody encephalitis), the spectrum of neuropsychiatric manifestations in the pediatric population is less clear. Psychosis, confusion, catatonia, and additional behavioral changes, along with seizures, encephalopathy, and movement disorders, may be initial manifestations or concurrent features in all age groups...

BACKGROUND: Rotavirus can rarely cause severe complications such as encephalopathy/encephalitis, myocarditis, sudden unexpected death, urinary stone, and gastrointestinal bleeding; indeed incidence of these severe complications remains unclear. Additionally, it has not been determined whether rotavirus vaccine could reduce the cases with the severe complications or not. METHOD: A two-part questionnaire was designed to determine the number and clinical features of the cases with the severe complications between September 1st 2008 and August 31st 2015 including the observation periods before and after rotavirus vaccine introduction in Aichi prefecture...

BACKGROUND: Although rare, symptomatic hyperammonemia is sometimes associated with valproic acid (VPA), especially in children. L-carnitine (levocarnitine), sometimes classified as an essential amino acid, is vital to mitochondrial utilization of fatty acids and can be helpful in treating this condition. The data supporting this, however, are limited. STUDY QUESTION: The aim of the study was to illustrate the role of L-carnitine in the treatment of patients with VPA-induced hyperammonemic encephalopathy (VPE) at 2 different institutions...

REVIEW
Rachael Hough, Ajay Vora
The improvement in overall survival in children with acute lymphoblastic leukemia (ALL) over the last 5 decades has been considerable, with around 90% now surviving long term. The risk of relapse has been reduced to such an extent that the risk of treatment-related mortality is now approaching that of mortality caused by relapse. Toxicities may also lead to the suboptimal delivery of chemotherapy (treatment delays, dose reductions, dose omissions), potentially increasing relapse risk, and short- and long-term morbidity, adding to the "burden of therapy" in an increasing number of survivors...

Posterior reversible encephalopathy syndrome (PRES) is a neurological disorder characterized by signs of posterior cerebral edema upon radiographic examination. A 16-year-old girl was involved in motorcycle accident and depressed frontal fracture was presented. She had generalized seizures 3 days after dural repair and fracture reduction. Signal changes was noted on both parietal lobes in the magnetic resonance images and it was completely resolved in 3 months follow-up. We would like to present the case that demonstrated PRES related hypertension after head trauma surgery for cerebrospinal fluid leakage in pediatric patient without any underlying disease...

Posterior reversible encephalopathy syndrome (PRES) in children with acute lymphoblastic leukemia has been increasingly recognized as a clinicoradiological entity. Our aim was to describe the incidence of PRES in pediatric patients with ALL, identify its risk factors, and examine its prognostic importance. For this research, we conducted a systematic, retrospective review of the patient records in a population-based series of children with acute lymphoblastic leukemia (n=643) treated in Finland from 1992 to 2008...

Pediatric epilepsies are a group of disorders with a broad phenotypic spectrum that are associated with great genetic heterogeneity, thus making sequential single-gene testing an impractical basis for diagnostic strategy. The advent of next-generation sequencing has increased the success rate of epilepsy diagnosis, and targeted resequencing using genetic panels is the a most cost-effective choice. We report the results found in a group of 87 patients with epilepsy and developmental delay using targeted next generation sequencing (custom-designed Haloplex panel)...

OBJECTIVE: Anti-N-methyl-d-aspartate receptor encephalitis (a-NMDARe) is an acute or subacute encephalopathy where electroencephalogram (EEG) is frequently obtained as part of the workup. Although no diagnostic EEG finding has been described so far, the definition of specific or typical patterns might help to distinguish this group among various encephalopathies of childhood. We examined EEG recordings of our patients with a-NMDARe in order to describe the most frequent findings. METHODS: Clinical and laboratory data and digital EEG recordings of 12 pediatric patients diagnosed with a-NMDARe in two major child neurology centers are evaluated...

The aim of this study was to clarify the picture of vitamin B1 deficiency (VB1D) caused by excessive soft drink consumption in Japan. A nationwide survey of children with soft drink-induced VB1D was conducted using a structured research form. Patient information was obtained from two sources: training hospitals for board-certified pediatricians and those identified by a database search. We obtained data from 33 children. Twenty-one children had a non-nurturing home environment. The median duration of excessive soft drink intake was 3...

BACKGROUND: There are no clinical features or biomarkers that can reliably differentiate acute disseminated encephalomyelitis from multiple sclerosis at the first demyelination attack. Consequently, a final diagnosis is sometimes delayed by months and years of follow-up. Early treatment for multiple sclerosis is recommended to reduce long-term disability. Therefore, we intend to explore neuroimaging biomarkers that can reliably distinguish between the two diagnoses. METHODS: We reviewed prospectively collected clinical, standard MRI and diffusion tensor imaging data of 12 pediatric patients who presented with acute demyelination with and without encephalopathy...

BackgroundHypoxic-ischemic encephalopathy (HIE) is a major cause of neonatal morbidity and mortality. Therapeutic hypothermia (TH) is the only available intervention, but neuroprotection is incomplete and variable. Seizures are common in infants with HIE undergoing TH and may worsen outcome. Phenobarbital (PB) is sometimes added, although use of prophylactic PB is controversial in the neonate. We hypothesize that prophylactic PB will not reduce, and may enhance, the neuroprotective effects of TH on brain injury and motor outcomes in the postnatal day 10 (P10) hypoxic-ischemic (HI) rat...

PURPOSE: The aim of this study was to assess the clinical characteristics of hypertensive encephalopathy according to the underlying etiologies in children. METHODS: We retrospectively evaluated 33 pediatric patients who were diagnosed as having hypertensive encephalopathy in Chonbuk National University Children's Hospital. Among the patients, 18 were excluded because of incomplete data or because brain magnetic resonance imaging (MRI) was not performed. Finally, 17 patients were enrolled and divided into a renal-origin hypertension group and a non-renal-origin hypertension group according to the underlying cause...

OBJECTIVES: Posterior reversible encephalopathy syndrome (PRES) is one of the most common neurological complications in hematology-oncology pediatric patients. Despite an increasingly recognized occurrence, no clear consensus exists regarding how best to manage the syndrome, because most cases of PRES have reported in single-case reports or small series. Aim of this paper is to identify incidence, clinical features, management, and outcome of PRES in a large series of hematology-oncology pediatric patients...
