Seizures, transient disruptions of normal brain electrical activity, are common for patients with low-grade glioma (LGG) and significantly affect quality of life. Up to 75% of patients with a LGG will have seizures in the course of their disease (compared with 1%-2% of the general population). Depending on the type of abnormal electrical activity, the(More)
We describe a 16-year-old boy with an 8.6Mb interstitial deletion of chromosome 4q 13.3q21.23 identified by oligo array-CGH. The patient presents psychomotor developmental delay, absent speech, marked progressive growth restriction, hearing loss, skeletal defects and minor facial anomalies.

Acute or subacute cerebellar inflammation is mainly caused by postinfectious, toxic, neoplastic, vascular, or idiopathic processes and can result in cerebellar ataxia. Previous magnetic resonance (MR) studies in single patients who developed acute or subacute ataxia showed varying imaging features. Eighteen patients presenting with acute and subacute onset(More)
Regadenoson is an FDA approved adenosine receptor agonist which increases blood–brain barrier (BBB) permeability in rodents. Regadenoson is used clinically for pharmacologic cardiac stress testing using SPECT or CT imaging agents that do not cross an intact BBB. This study was conducted to determine if standard doses of regadenoson transiently disrupt the(More)
Coagulase-negative staphylococci cause a significant number of infections, especially in immunocompromised patients, including premature neonates. Nosocomial strains present in the environment create a special risk.We studied staphylococci isolated from the intensive care unit of a paediatric teaching hospital over the period of six months in 1997.(More)
