This study investigated the immediate effects of stimulant medication (methylphenidate) on cognitive attention processes in children with attention-deficit-hyperactivity disorder (ADHD). Thirteen males and two females (mean age 9 y 5 mo, SD 18.3 mo) with a diagnosis of ADHD and who were to be prescribed methylphenidate were assessed twice on one day with(More)
OBJECTIVES To develop an Index-based, seven subtest, short-form of the Wechsler intelligence scale for children fourth edition (WISC-IV) that offers the same comprehensive range of analytic methods available for the full-length version. DESIGN AND METHODS Psychometric. RESULTS The short-form Indexes had high reliability and criterion validity. Scores(More)
Reorganization of eloquent cortex enables rescue of language functions in patients who sustain brain injury. Individuals with left-sided, early-onset focal epilepsy often show atypical (i.e. bilateral or right-sided) language dominance. Surprisingly, many patients fail to show such interhemispheric shift of language despite having major epileptogenic(More)
Despite increasing research into the severe effects of childhood memory disorders, there is currently a paucity of evidence available to inform the design of appropriate rehabilitation strategies. Indeed, within the paediatric literature there is no model that links specific memory disorders with hypotheses for appropriate rehabilitation strategies. This(More)
OBJECTIVES The aim of this study is to determine which maneuvers result in greatest cross-sectional area (CSA) of the internal jugular vein (IJV) and reduce collapsibility as measured by ultrasound during simulated venipuncture. METHODS A total of 52 healthy adult volunteers were prospectively studied in an academic emergency department. Cross-sectional(More)

Lifestyle modification has been demonstrated to effectively reduce the risk factors associated with chronic disease. The Complete Health Improvement Project, a 30-day diet and lifestyle modification program, has been shown to be efficacious in the US, Australasia and Canada. The present study examined the changes in selected biometric measures of 61(More)
Increased concerns over the safety of air medical transport have prompted development of novel ways to increase safety. The objective of our study was to determine if an Internet streaming media safety video increased crew safety knowledge. 23 out of 40 crew members took an online safety pre-test, watched a safety video specific to our program and completed(More)
