The pediatric stroke outcome measure: a validation and reliability study.

Background And Purpose: The Pediatric Stroke Outcome Measure (PSOM) is an objective, disease-specific outcome measure containing 115 test items suitable for newborn to adult ages. The PSOM measures neurological deficit and function across 5 subscales: right sensorimotor, left sensorimotor, language production, language comprehension, and cognitive/behavior yielding a final 10-point deficit score. The goal of this study was to examine PSOM construct validity in measuring neurological outcome in pediatric stroke survivors and interrater reliability (IRR) for both prospective and retrospective scoring.

Breath acetone predicts plasma ketone bodies in children with epilepsy on a ketogenic diet.

Objective: The high-fat ketogenic diet has long been used to treat refractory childhood seizures, but whether there is a relation between the degree of ketosis and effectiveness of seizure control remains unclear. Frequent measurements of plasma ketones are difficult in children so the goal was to determine the utility of breath acetone as a marker of systemic ketosis and seizure control in children given the ketogenic diet because of seizures refractory to medication.

Methods: In experiment I, breath acetone and plasma ketones were assessed every 2 h during an 8-h test day in seven children.

Neonatal arterial ischemic stroke and cerebral sinovenous thrombosis are more commonly diagnosed in boys.

The risk factors for arterial ischemic stroke and cerebral sinovenous thrombosis in neonates are not well understood. We looked at gender, birthweight, and gestational age in neonates with arterial ischemic stroke and cerebral sinovenous thrombosis to see if there were trends suggesting that these were risk factors. We identified neonates with a gestational age at birth > or = 36 weeks and a diagnosis of arterial ischemic stroke or cerebral sinovenous thrombosis made by computed tomography or magnetic resonance imaging during the neonatal period from a consecutive cohort study of children with arterial ischemic stroke and cerebral sinovenous thrombosis in Ontario.

Intra-arterial tissue plasminogen activator for thrombosis complicating cerebral angiography in a 17-year-old girl.

Few reports describe the use of intraarterial recombinant tissue plasminogen activator to treat intracranial thrombosis in children. A 17-year-old girl with a history of prior venous thrombosis developed a left middle cerebral artery thrombus during diagnostic cerebral angiogram. Therapy with intra-arterial tissue plasminogen activator was initiated.

A prospective study: growth and nutritional status of children treated with the ketogenic diet.

Objective: To assess the nutritional status of children treated with the classic and medium-chain triglyceride (MCT) ketogenic diets.

Design: A prospective, nonrandomized study design was used to measure nutrient intakes, growth, and biochemical indexes of children, age 1 to 16 years, with intractable epilepsy before and after 4 months' treatment with the classic and MCT ketogenic diets. None of the children had been on earlier dietary regimens.

Epilepsy and the ketogenic diet: assessment of ketosis in children using breath acetone.

High-fat ketogenic diets increase ketones (acetoacetate, beta-hydroxybutyrate, and acetone) and are used to treat refractory seizures. Although ketosis is an integral aspect of these therapeutic regimens, the direct importance of ketosis to seizure control needs further investigation. An examination of this relationship requires a reliable, minimally invasive measure of ketosis that can be performed frequently.
