AIM: To evaluate the performance of a neurologic assessment protocol among jaundiced infants requiring exchange transfusion (ET). METHODS: We identified infants in a referral children's hospital who received ET and those who met the American Academy of Pediatrics (AAP) criteria for ET based on total serum bilirubin (TSB) levels. The performance of a bilirubin-induced neurologic dysfunction (BIND-M) scoring protocol for acute bilirubin encephalopathy (ABE) in detecting infants treated with ET in both groups was investigated by logistic regression analysis and c-statistic...

Central nervous system (CNS) involvement in Henoch-Schonlein purpura (HSP) is rare but poses diagnostic difficulties. The aim of the study was to establish the frequency of CNS involvement in HSP, to analyze its clinical characteristics and do a literature review. Medical files of patients with HSP admitted at the Department of Pediatrics, Plovdiv, were studied retrospectively for a five-year period (2009-2013). Diagnosis was based on the American College of Rheumatology criteria. Out of 112 children with HSP 1 case (0...

Despite a wide number of studies trying to define clinical, physiopathological, and neuroradiological features of posterior reversible encephalopathy syndrome (PRES), the true nature of symptoms is still not fully understood. We studied a standard cohort of 24 pediatric patients, affected by hemato-oncological diseases, with a neuroradiological diagnosis consistent with PRES identified from 2006 to 2013. Ten of them developed PRES after hematopoietic stem cell transplantation. We analyzed the sequence of clinical, radiological, and electrophysiological data...

OBJECTIVE: Research using neonatal electroencephalography (EEG) has been limited by a lack of a standardized classification system and interpretation terminology. In 2013, the American Clinical Neurophysiology Society (ACNS) published a guideline for standardized terminology and categorization in the description of continuous EEG in neonates. We sought to assess interrater agreement for this neonatal EEG categorization system as applied by a group of pediatric neurophysiologists. METHODS: A total of 60 neonatal EEG studies were collected from three institutions...

BACKGROUND: Virus-associated acute encephalopathy (VAE) is a severe central nervous system complication caused by common viral infections in children. The pathophysiology of VAE is thought to be endothelial injury. This study was designed to establish an in vitro VAE model for evaluating endothelial injury caused by the proinflammatory cytokine TNF-α. METHODS: Transwell-grown human umbilical vein endothelial cells (HUVECs) monolayers were incubated with serially diluted TNF-α...

Non-standard exception requests (NSERs), for which transplant centers provide patient-specific narratives to support a higher MELD/PELD score, are made for > 30% of pediatric liver transplant candidates. We describe the justifications used in pediatric NSER narratives 2009-2014 and identify justifications associated with NSER denial, waitlist mortality, and transplant. Using UNOS data, 1,272 NSER narratives from 1,138 children with NSERs were coded for analysis. The most common NSER justifications were failure-to-thrive (48%) and risk of death (40%); both associated with approval...

BACKGROUND: Cardiopulmonary injury is common in neonatal encephalopathy, but the link with cerebrovascular dysfunction is unknown. We hypothesized that cerebral autoregulation is associated with cardiopulmonary injury in neonates treated with therapeutic hypothermia (TH) for neonatal encephalopathy. METHODS: The cerebral hemoglobin volume index (HVx) from near-infrared spectroscopy was used to identify the mean arterial blood pressure (MAP) with optimal autoregulatory vasoreactivity (MAPOPT)...

BACKGROUND: Hospital-acquired pressure injuries (HAPIs) can be caused by multiple factors including pressure, shear, friction, moisture/incontinence, device-related pressure, immobility, inactivity, and nutritional deficits. Along with immobility, medical device-related (MDR) HAPIs are a primary cause of pressure injury in neonates, as the clinical practice setting has become increasingly technologically advanced. It is estimated that up to 50% of HAPIs are MDR in pediatric patients. Neonates are at particular risk for HAPI because of their specific anatomical, physiological, and developmental vulnerabilities...

Recently, studies in adults with acute promyelocytic leukemia (APL) showed high cure rates in low-risk patients treated with all-trans retinoid acid (ATRA) and arsenic trioxide (ATO), while toxicities were significantly reduced compared to the standard treatment with ATRA and chemotherapy. Here we report about first experience with 11 pediatric patients with low-risk APL treated with ATRA and ATO. All patients stayed in molecular remission. All suffered from hyperleukocytosis. Two patients experienced reversible severe side effects...

BACKGROUND: Vitamin D has neuroprotective and immunomodulatory properties, and deficiency is associated with worse stroke outcomes. Little is known about effects of hypoxia-ischemia or hypothermia treatment on vitamin D status in neonates with hypoxic-ischemic encephalopathy (HIE). We hypothesized vitamin D metabolism would be dysregulated in neonatal HIE altering specific cytokines involved in Th17 activation, which might be mitigated by hypothermia. METHODS: We analyzed short term relationships between 25(OH) and 1,25(OH)2 vitamin D, vitamin D binding protein, and cytokines related to Th17 function in serum samples from a multicenter randomized controlled trial of hypothermia 33(0)C for 48h after HIE birth versus normothermia in 50 infants with moderate to severe HIE...

BACKGROUND: High-dose erythropoietin (Epo) is a promising neuroprotective treatment in neonates with hypoxic ischemic encephalopathy (HIE) receiving hypothermia. We evaluated the pharmacokinetics and dose-exposure relationships of high-dose Epo in this population to inform future dosing strategies. METHODS: We performed a population pharmacokinetic analysis of 47 neonates with HIE treated with hypothermia who received up to 6 doses of Epo in two previous clinical trials...

BACKGROUND: The severity of the initial encephalopathy in neonatal hypoxic-ischemic encephalopathy correlates with seizure burden. Early electroencephalograph (EEG) background activity reflects the severity of encephalopathy. Thus, we hypothesized that early EEG background would be predictive of subsequent seizures in neonatal hypoxic-ischemic encephalopathy. METHODS: This study included infants undergoing therapeutic hypothermia at St. Louis Children's Hospital between January 2009 and April 2013...

Posterior reversible encephalopathy syndrome (PRES) and cerebral sinus thrombosis are 2 known complications of acute lymphoblastic leukemia and its treatment. We describe a patient with acute lymphoblastic leukemia whose course was complicated by both of these conditions. This case is novel both for the fact that PRES developed before the initiation of therapy and that PRES was followed shortly by the development of cerebral sinus thrombosis. Our patient's story raises questions about our current understanding of the pathophysiology of PRES, and it suggests that PRES may actually be a predisposing risk factor for cerebral sinus thrombosis...
