Injury to the preterm brain and cerebral palsy: clinical aspects, molecular mechanisms, unanswered questions, and future research directions.

Cerebral palsy will affect nearly 10% of the 60,000 very low-birth-weight infants born in the United States in the next year, and an even greater percentage will display some form of permanent neurological impairment resulting from injury to the preterm brain. The 2008 Neurobiology of Disease in Children Symposium, held in conjunction with the 37th annual meeting of the Child Neurology Society, aimed to define current knowledge and to develop specific aims for future clinical, translational, and fundamental science. A complex interplay of both destructive and developmental forces is responsible for injury to the preterm brain.

Tumors of the central nervous system: clinical aspects, molecular mechanisms, unanswered questions, and future research directions.

Central nervous system tumors are the most common solid tumors in children. Many histological subtypes and biological variants exist. The 2007 Neurobiology of Disease in Children Symposium, held in conjunction with the 36th annual meeting of the Child Neurology Society, aimed to define current knowledge in the field and to develop specific aims for future clinical, translational, and fundamental science.

Targeting hyaluronan interactions in malignant gliomas and their drug-resistant multipotent progenitors.

Purpose: To determine if hyaluronan oligomers (o-HA) antagonize the malignant properties of glioma cells and treatment-resistant glioma side population (SP) cells in vitro and in vivo.

Experimental Design: A single intratumoral injection of o-HA was given to rats bearing spinal cord gliomas 7 days after engraftment of C6 glioma cells. At 14 days, spinal cords were evaluated for tumor size, invasive patterns, proliferation, apoptosis, activation of Akt, and BCRP expression.

Spinal muscular atrophy: classification, diagnosis, management, pathogenesis, and future research directions.

Spinal muscular atrophy is an autosomal recessive neurodegenerative disorder that affects the motor neurons responsible for movement of the proximal muscles of the trunk and body. To date, the disease can be classified into 3 main categories based on severity and age of onset. During the October 18th symposium held in Pittsburgh, Pennsylvania, researchers met to (1) describe current diagnostic strategies, (2) discuss recent thoughts on pathogenesis, (3) review current therapies and clinical trials, and (4) define future research directions.
