The value of the use of plasma B-type natriuretic peptide among acute ischemic stroke patients in a Chinese emergency department.
To determine the value of the use of plasma B-type natriuretic peptide (BNP) among acute ischemic stroke patients in a Chinese emergency department (ED). ⋯ Plasma BNP level is significantly higher in CE patients than in other TOAST subtypes, and by using Biosite Triage(®)BNP POCT platform, emergency physicians should strongly consider CE subtype with the plasma BNP level of over 66.50 pg/ml. However, the single BNP biomarker panel cannot be used to confidently rule out or identify stroke subtypes as a diagnosis and must be taken in context with clinical assessment and judgment before making management decisions in the ED.

Complications following cranioplasty using autologous bone or polymethylmethacrylate--retrospective experience from a single center.
A decompressive hemicraniectomy is a potentially life-saving intervention following head trauma. Once performed patients are obliged to undergo a second procedure with cranioplasty. Two of the most commonly used materials are autologous bone and polymethylmethacrylate (PMMA). We have now evaluated complications following a cranioplasty using these materials. ⋯ In our series we had a high percentage of patients needing re-operation due to complications following a cranioplasty. Though generally considered a straightforward procedure, complications and associated morbidity in patients undergoing cranioplasty should not be underestimated.

Management of the optic canal invasion and visual outcome in spheno-orbital meningiomas.
Spheno-orbital meningiomas often present with visual deficit due to invasion of the optic canal by the tumor. This study discusses the reasons of visual impairment, the choice of the surgical approach according to the type of optic canal involvement, and the factors correlated to the visual outcome in patients harboring a spheno-orbital meningioma. ⋯ The invasion of the optic canal by the tumor is the main reason of visual dysfunction in patients with spheno-orbital meningiomas. A wide opening of the optic canal must be performed routinely in patients with orbital apex and diffuse orbital tumors, where there is concentric invasion of the optic canal wall. In these cases the supraorbital-pterional approach is the technique of choice. In selected cases with lateral intraorbital tumors and invasion of the lateral aspect of the optic canal the complete tumor resection coupled with good decompression of the optic nerve may be achieved via a less invasive lateral orbitocranial approach without craniotomy.

Lumbar laminectomy and fusion with routine local application of vancomycin powder: decreased infection rate in instrumented and non-instrumented cases.
Wound infections are one of the most common and potentially devastating complications of spinal surgery. Intra-wound application of vancomycin powder has been shown to lower the infection risk following posterior instrumented fusion, but little evidence supports use in other spinal operations. The goal of this study is to assess the efficacy of vancomycin powder for lumbar laminectomy and fusion, both instrumented and non-instrumented. ⋯ Local vancomycin powder appears to lower the risk of wound infection following lumbar laminectomy and fusion, both instrumented and non-instrumented. Further studies are needed to optimize dosing of vancomycin powder, assess long-term safety and efficacy, and evaluate use in other spinal operations.

Hypo-fractionated IMRT for patients with newly diagnosed glioblastoma multiforme: a 6 year single institutional experience.
Glioblastoma (GBM) is the most common malignant primary brain tumour in adults. Surgery and radiotherapy constitute the cornerstones for the therapeutic management of GBM. The standard treatment today is maximal surgical resection followed by concomitant chemo-radiation therapy followed by adjuvant TMZ according to Stupp protocol. Despite the progress in neurosurgery, radiotherapy and oncology, the prognosis still results poor. In order to reduce the long time of standard treatment, maintaining or improving the clinical results, in our institute we have investigated the effects of hypo-fractionated radiation therapy for patients with GBM. ⋯ The hypo-fractionated radiation therapy can be used for patients with GBM, resulting in favourable overall survival, low rates of toxicity and satisfying QoL. Future investigations are needed to determine the optimal fractionation for GBM.
