Surgical hemostatic agents: assessment of drugs and medical devices.

Surgical hemostatic agents are indicated to improve hemostasis when conventional techniques (compression, sutures or electrocoagulation) are inadequate. The National French Authority for Health (Haute Autorité de santé [HAS]) set out to assess these products (medical devices and agents) to determine their optimal utility. This evaluation included one class of products containing some form of human fibrinogen and thrombin and eight classes of medical devices and automated devices to prepare autologous fibrin.

Retrospective comparison of chemoradiotherapy followed by adjuvant chemotherapy, with or without prior gliadel implantation (carmustine) after initial surgery in patients with newly diagnosed high-grade gliomas.

Purpose: Retrospective study of patients treated for high-grade glioma, with or without biodegradable carmustine wafers and according to the Stupp protocol.

Methods And Materials: Between May 2007 and June 2008, 65 patients underwent surgery for high-grade glioma, 28 had implantation of Gliadel and 37 patients did not. Patients received radiotherapy with concomitant temozolomide followed by 5 consecutive days of temozolomide every month for 6 months.

Toward improved grading of malignancy in oligodendrogliomas using metabolomics.

In spite of having been the object of considerable attention, the histopathological grading of oligodendrogliomas is still controversial. The determination of reliable biomarkers capable of improving the malignancy grading remains an essential step in working toward better therapeutic management of patients. Therefore the metabolome of 34 human brain biopsies, histopathologically classified as low-grade (LGO, N = 10) and high-grade (HGO, N = 24) oligodendrogliomas, was studied using high-resolution magic angle spinning nuclear magnetic resonance spectroscopy (HRMAS NMR) and multivariate statistical analysis.

[Acute myelitis and Lyme disease].

Introduction: Acute myelitis accounts for 4 to 5 percent of all cases of neuroborreliosis. In the literature, simultaneous spinal MRI and cerebrospinal fluid (CSF) investigations are presented for only 8 cases. We describe here 3 cases of acute Lyme myelitis.

[Intradiploic encephalocele in an adult. A case report and review of the literature].

We describe a rare case of parietal intradiploic encephalocele in a 51-year-old woman with no history of head trauma. The patient presented with a 1-month history of left hemiparesthesia. A hard indolent scalp lesion was palpable on examination in the right parietal area.
