Secondary complications (SC) after intracerebral hemorrhage (ICH) can worsen outcome and are associated with early death. The purpose of the present study was to determine in-hospital mortality rates and SC after spontaneous ICH during acute care stay in a population-based cohort in central Europe. ⋯ Surgical treatment of hematomas is associated with an increased rate of SC, but not with higher mortality rates compared with conservatively treated patients. The prevention of an accumulation of SC could lead to a decrease of in-hospital mortality after spontaneous ICH.

Comparative Study Controlled Clinical Trial
Comparison of Conventional and Kilohertz Frequency Epidural Stimulation in Patients Undergoing Trialing for Spinal Cord Stimulation: Clinical Considerations.
Compare therapeutic response of patients to conventional versus high-frequency spinal cord stimulation (SCS). ⋯ HFS significantly altered the feeling of paresthesias in the majority of patients (ten of 12), was preferred to LFS in five of 12 patients, and non-inferior to LFS in eight of 12 patients. Both 4 kHz and 10 kHz stimulation allowed patients to benefit from HFS. HFS allowed maximum voltage stimulation without discomfort.

Comparative Study
Relationship between clinical features and T2-weighted magnetic resonance images in symptomatic Rathke's cleft cysts.
It is not known when surgery is appropriate for the treatment for incidental Rathke cleft cysts because knowledge of their natural history is lacking. In this study, we sought to determine whether symptomatic Rathke cleft cysts could be distinguished by their signal intensities in magnetic resonance (MR) images. We analyzed the relationship between these signal intensities and clinical manifestations of the cysts and their patterns of expansion. ⋯ We conclude that Rathke cleft cysts that show an MR signal intensity similar to that of cerebrospinal fluid grow slowly and are frequently diagnosed as cysts associated with visual disturbance when they become large. It may be possible to predict the clinical progression of Rathke cleft cysts by assessing MR signal intensities.

Early versus Delayed Surgical Decompression of Spinal Cord after Traumatic Cervical Spinal Cord Injury:A Cost-Utility Analysis.
This cost-utility analysis was undertaken to compare early (≤24 hours since trauma) versus delayed surgical decompression of spinal cord to determine which approach is more cost effective in the management of patients with acute traumatic cervical spinal cord injury (SCI). ⋯ The results of this economic analysis suggests that early decompression of spinal cord was more cost effective than delayed surgical decompression in the management of patients with motor complete and incomplete SCI, even though no strategy was clearly dominant.

Case Reports
Intraventricular bone wax as cause of recurrent CSF infection: a neuroradiological pitfall.
Persistent or recurrent shunt infections can be secondary to predisposing factors, such as isolated compartments, cerebrospinal fluid leaks, or foreign bodies. ⋯ To our knowledge, this is the first report of intraventricular bone wax causing persistent CSF infection. The diagnosis was difficult because wax resembles air on computed tomography and on magnetic resonance imaging, and so it had been not noticed for months. Only its persistence on several images raised the suspicion of foreign body inside the ventricular system.
