Case Reports Comparative StudyMethionine positron emission tomography of recurrent metastatic brain tumor and radiation necrosis after stereotactic radiosurgery: is a differential diagnosis possible?
In this study the authors examined how to differentiate radiation necrosis from recurrent metastatic brain tumor following stereotactic radiosurgery by using positron emission tomography (PET) with L-[methyl-11C]methionine (MET). ⋯ The use of MET-PET scanning is a sensitive and accurate technique for differentiating between metastatic brain tumor recurrence and radiation necrosis following stereotactic radiosurgery. This study reveals important information for creating strategies to treat postradiation reactions.

Edema after intracerebral hemorrhage: correlations with coagulation parameters and treatment.
Development of edema is known to contribute to poor outcome after spontaneous intracerebral hemorrhage (ICH). Recent research has identified thrombin as a key mediator in the development of edema in animal models; however, little has been published correlating the coagulation cascade and edema in humans. ⋯ The authors propose that factors released from activated platelets at the site of hemorrhage, for example vascular endothelial growth factor, may interact with thrombin to increase vascular permeability and contribute to the development of edema.

Outcomes of surgery in 1019 brachial plexus lesions treated at Louisiana State University Health Sciences Center.
Outcomes of 1019 brachial plexus lesions in patients who underwent surgery at Louisiana State University Health Sciences Center during a 30-year period are reviewed in this paper to provide management guidelines. ⋯ Surgical exploration and repair of brachial plexus lesions is technically feasible and favorable outcomes can be achieved if patients are thoroughly evaluated and appropriately selected.

Complications of invasive subdural grid monitoring in children with epilepsy.
This study was performed to evaluate the complications of invasive subdural grid monitoring during epilepsy surgery in children. ⋯ The results of this study indicate that carefully selected pediatric patients with intractable epilepsy can benefit from subdural invasive monitoring procedures that entail definite but acceptable risks.

Changes in cerebrospinal fluid hydrodynamics following endoscopic third ventriculostomy for shunt-dependent noncommunicating hydrocephalus.
The aim of this study was to analyze physiological changes in cerebrospinal fluid (CSF) dynamics following endoscopic third ventriculostomy (ETV) for shunt-dependent noncommunicating hydrocephalus. ⋯ Our data suggest that CSF dynamics convert from a shunt-dependent state to a shunt-independent state within I week following ETV in patients with shunt-dependent noncommunicating hydrocephalus. Nonetheless, intraventricular pressure does not decrease quickly in certain cases. Cerebrospinal fluid absorptive capacity or CSF circulation through the subarachnoid space may show further improvement several months after ETV.
