<h3>Objective:</h3> Higher latitude, lower ultraviolet exposure, and serum 25-hydroxyvitamin D (25OHD) correlate with higher multiple sclerosis (MS) prevalence, relapse rate, mortality. We therefore evaluated the effects of high-dose vitamin D2 (D2) in MS. <h3>Methods:</h3> Adults clinically active relapsing-remitting MS (RRMS) were randomized to 6 months9 double-blind placebo-controlled D2, 6,000 IU capsules, dose adjusted empirically aiming for a 25OHD 130–175 nM. All received daily...

Cranial CT scans are at the center of decision making in brain injuries children because their speed and ability to detect surgically relevant lesions. However, alternative techniques, such as conventional MRI may have advantages terms radiation exposure sensitivity injury. Susceptibility-weighted imaging (SWI), a relatively novel sequence, shows promise its detecting hemorrhagic lesions; however, clinical potential remains uncertain. In this observational study (5–16 years age) with...

DWI reportedly accurately differentiates pediatric posterior fossa tumors, but anecdotal experience suggests limitations. In 3 years, medulloblastoma and JPA were differentiated by alone in 23/26 cases (88%). Ependymoma (n = 5) could not be reliably from or JPA. A trend toward increased diffusion restriction higher grade tumors (1/14 I, 7%; 9/12 IV, 75%) had too much overlap to predict the of individual cases. The ADC between tumor types appeared partly due technical factors (in small,...

The purpose of this study was to investigate the frequency and spectrum magnetic resonance imaging (MRI) abnormalities in a population children with cerebral palsy (CP) who were born years 2000 2001 Victoria, Australia. In 2001, 221 (126 males, 95 females; mean age 6y [SD 7mo], range 5–7y) CP, excluding those CP due postneonatal causes (6% all cases), identified through Victorian Cerebral Palsy Register. All medical records systematically reviewed available brain comprehensively evaluated by...

Abstract Traumatic brain injury (TBI) in children results damage to the developing brain, particularly severely injured individuals. Little is known, however, of long‐term structural aspects following childhood TBI. This study investigated integrity 10 years post‐TBI using magnetic resonance imaging volumetrics a sample 49 participants with mild, moderate and severe TBI, evaluated against normative 20 individuals from pediatric database comparable age gender distribution. Structural was gray...

Perinatal asphyxia is a significant cause of death or long-term neurodevelopmental impairment. Hypothermia, currently the only effective treatment, leads to modest improvements, but new therapeutic strategies are required. Umbilical cord blood (UCB) mononuclear cells have potent anti-inflammatory properties and may reduce neuropathology. This study examined whether autologous UCB were neuroprotective when administered newborn lambs at 12 h after birth asphyxia. At caesarean section, was...

To review the authors' 15-year experience with bronchial artery embolization (BAE) for treatment of hemoptysis in young patients cystic fibrosis.By searching 1985-1999 radiology database, authors identified 23 who had been referred to department angiography. Twenty these underwent BAE. The medical records were retrospectively reviewed regard agents used, success rates, number repeat embolizations, survival times, and causes death.BAE was performed on 38 occasions 20 patients. mean age at...

Abstract Perinatal asphyxia remains a principal cause of infant mortality and long‐term neurological morbidity, particularly in low‐resource countries. No neuroprotective interventions are currently available.

We aimed determine effect melatonin patch) on neuropathology lamb model perinatal asphyxia. Asphyxia was induced newborn...
