Predictive value of intrathecal interleukin-6 for ventriculostomy-related Infection.
Early diagnosis of ventriculostomy-related infection (VRI) is crucial for the early treatment and course of this disease. In neurosurgical patients the diagnostic criteria are equivocal, mostly because of bloodstained cerebrospinal fluid (CSF). The predictive value, sensitivity and specificity of intrathecal interleukin-6 (IL-6 (CSF)) has been proven for VRI compared with classical diagnostic CSF parameters, i.e. cell countCSF (CC (CSF)) and total protein (CSF). ⋯ Our data indicate that IL-6 (CSF) is a reliable marker for predicting VRI prior to clinically manifest meningitis, one day earlier than the common diagnostic criteria of CSF infection (CC (CSF), total protein (CSF), clinical symptoms).

Electrode implantation for deep brain stimulation in dystonia: a fast spin-echo inversion-recovery sequence technique for direct stereotactic targeting of the GPI.
Deep brain stimulation (DBS) of the globus pallidus internus (GPi) is an effective treatment for medically refractory primary dystonia. We present our technique for direct preoperative visualization of the target using a fast spin-echo inversion-recovery (FSE-IR) sequence. ⋯ Inversion recovery sequences are an excellent tool for direct visualization of the GPi. These images can be fused to stereotactic MRI or CCT and may help to improve anatomical targeting of the GPi for the implantation of DBS electrodes.

Case ReportsFailure of deep brain stimulation of the posterior inferior hypothalamus in chronic cluster headache - report of two cases and review of the literature.
Deep brain stimulation (DBS) has become a standard procedure for movement disorders such as Parkinson's disease, essential tremor or dystonia. Recently, deep brain stimulation of the posterior hypothalamus has been shown to be effective in the treatment of drug-resistant chronic cluster headache. ⋯ Deep brain stimulation of the posterior inferior hypothalamus is an experimental procedure and should be restricted to selected therapy-refractory patients and should be performed in centers experienced in patient selection and performance of DBS as well as postoperative pain treatment. A prospective multi-centre study is necessary to evaluate its effectiveness.
