Cervical spine is the most kinetic segment of the whole vertebrae. The radiologic imaging methods concern with the morphologic changes but give no functional data. At flexion, spinal cord strains, anterior osteophytic compression increases. At extension, spinal canal gets narrower, cord shortens and gets thicker, compression of posterior ligament gets abberant and cord compression increases. ⋯ The changes of the cord compression and the transvers area of cord which is the most important prognostic indicator in spinal diseases and also the area of spinal cord and subarachnoid space can be detected via dynamic axial sections of MRI. Dynamic MR images may be helpfull in the decision making for the surgical treatment of CSM.

Review Meta Analysis
Effects of Intensive Blood Pressure Lowering on Intracerebral Hemorrhage Outcomes: A Meta-Analysis of Randomized Controlled Trials.
Elevation of blood pressure (BP) is common after intracerebral hemorrhage (ICH). Early BP treatment may be beneficial after ICH, but the effect of intensive BP lowering on ICH outcomes is not known and no systematic review or meta-analysis was published regarding this issue. ⋯ Acute lowering of SBP to 140 mmHg is probably beneficial for functional outcome in patients with ICH, but the evidence is still insufficient. Further large multicenter studies are required to enhance the evidence to guide the BP lowering target following ICH.

Colloid cysts are usually located in third ventricle and are believed to be derived from either primitive neuroepithelium or endoderm. Patients may remain asymptomatic for long time while some can present with paroxysmal headache, gait disturbance, nausea, vomiting, behavioral changes, weaknesses of lower limbs, impaired memory, new learning disability and sudden death. Computed tomography usually reveals a well-defined round or oval nonenhancing lesion. ⋯ Utilization of two instruments, the bi port technique and tubular retractor can be helpful in selected patients to overcome limitations. Although total excision should be aimed, subtotal excision and coagulation of residual cyst wall usually results in good long-term results without any growth of remnant wall. Conversion to an open procedure may be required in some patients.

Randomized Controlled Trial
Neuroprotective Effects of Erythropoietin in Patients with Severe Closed Brain Injury.
Our research was focused on the neuroprotective function of erythropoietin (Epo) in patients with severe closed traumatic brain injury (TBI). ⋯ The study provides evidence of lower mortality and better neurological outcome for the patients who received Epo increasing the possibility that Epo therapy could be used in clinical practice, limiting neuronal damage induced by TBI.

The surgical treatment of spinal metastases is still controversial. Due to developments in diagnostic imaging there has been a great evolution in minimally invasive surgical techniques for the spinal surgery. Most of the patients with spinal metastases are debilitated and under high risk of major surgical morbidity and mortality. ⋯ Minimal invasive techniques represent major advance in minimizing approach related morbidity in the treatment of spinal tumors. Because of the evolution of minimally invasive surgical techniques for the spinal surgery, minimally invasive techniques are alternative treatment to standard open approaches for the treatment of metastatic spinal tumors. Due to less complication rates there has been a trend toward the minimalization of spine surgery.
