Clinical TrialIntravascular hypothermia for acute hemorrhagic stroke: a pilot study.
The use of intravascular hypothermia in the treatment of hemorrhagic stroke is currently still being researched. The exact therapeutic properties and effect of hypothermia on the natural progression of the disease are not known, and a only small number of papers has been published with results from these studies. Mild hypothermia at 34°C was induced in six patients with hemorrhagic stroke in the first 48 h after presentation, using an intravascular catheter placed in the inferior vena cava. ⋯ The patients were then followed up using the modified Rankin Scale (mRS) for 6 months and 1 year. There was a statistically significant improvement at 6 months and 1 year follow-up using the mRS score in the hypothermia group, indicating a possible beneficial effect of early therapeutic hypothermia in the management of acute hemorrhagic stroke. However, a larger study is needed in order to confirm our finding.

The effectiveness of endoscopic epidurolysis in treatment of degenerative chronic low back pain: a prospective analysis and follow-up at 48 months.
The aim of this prospective study was to evaluate the efficacy of endoscopic epidurolysis in the treatment of degenerative chronic low back pain. Two hundred and thirty four patients affected by chronic low back pain, with VAS ≥ 5 and Oswestry Low Back Pain Disability Index (ODI) from 0 to 60% (0-20%, group A; 20-40%, group B; 40-60%, group C) were enrolled and treated prospectively with endoscopic epidurolysis by means of a flexible fiberoptic endoscope introduced into the caudal epidural space and by the intermittent instillation of saline solution added with 150 UI hyaluronidase. Targeted application of ozone (8 ml; 38 γ/ml) and 50 mg ciprofloxacin close to the abnormal areas was also performed. ⋯ The treatment significantly reduced VAS score in all three groups of patients starting from the first week and throughout the entire follow-up period (P < 0.001). Disability Index (ODI) too showed encouraging results (P < 0.001) that was particularly evident at 3 months and maintained up to long-term follow-up intervals. Epiduroscopy by mechanical adhesiolysis and administration on targeted areas of ciprofloxacin and ozone seems to be, in this prospective study, an effective technique to provide a sensible and persisting pain relief and act of improving ODI in chronic low back pain.

ReviewHypoperfusion in the acute phase of subarachnoid hemorrhage.
Acute disruption of cerebral perfusion and metabolism is a well-established hallmark of the immediate phase after subarachnoid hemorrhage (SAH). It is thought to contribute significantly to acute brain injury, but despite its prognostic importance, the exact mechanism and time course is largely unknown and remains to be characterized. ⋯ Acute vasospasm, cytotoxic edema and a general metabolic stress response occur immediately after experimental SAH. Prophylactic treatment with hypothermia or ET-A antagonists can correct these disturbances in the experimental setting. Clinically, prolonged and ICP-independent hypoperfusion was also confirmed. As the initial phase is of particular importance regarding the neurological outcome and is amenable to beneficial intervention, the acute stage after SAH demands further investigation and warrants the exploration of measures to improve the immediate management of SAH patients.

Clinical TrialRole of controlled lumbar CSF drainage for ICP control in aneurysmal SAH.
a prospective study of lumbar CSF drainage in the setting of raised intra-cranial pressure refractory to medical management and ventriculostomy placement is presented. There has been increasing data that this may be a effective and safe intervention for reduction of ICP. ⋯ we have shown that controlled lumbar drainage is a safe, efficacious and minimally invasive method for treatment of elevated ICP which refractory to medical management. Ventriculostomies are always placed before utilizing lumbar drains to minimize the risk of cerebral herniation. We would advocate making controlled lumbar drainage a standard part of ICP control protocols.

Delayed intracranial hemorrhage associated with antiplatelet therapy in stent-assisted coil embolized cerebral aneurysms.
Administration of oral clopidogrel plus aspirin is the most important regimen to reduce thromboembolic complications in stent-assisted coil embolization of cerebral aneurysm. However, such therapy may increase the risk of hemorrhage. The purpose of this study is to analyze the effect of two different antiplatelet regimens on hemorrhagic and thromboembolic complication rates around the stent-assisted coil embolization period. ⋯ The thromboembolic complication rates were not significantly different between the two groups. Oral administration of routine antiplatelet drugs for 3 days before stent-assisted coil embolization possibly increases the risk of delayed intracranial hemorrhage, compared to loading group. Symptomatic thromboembolic complications have no significant difference in the two different regimens.
