prognostic factors associated with disease progression have been identified in patients with atypical meningiomas. However, in most studies a limited sample size precluded a meaningful multivariate analysis. Reports of prognostic factors after multivariate modeling include a high mitotic index, 10 , 12 , 23 Simpson surgical grading, 5 sheeting, 12 presence of necrosis, 12 pial and brain invasion, 16 , 23 lack of PORT, 12 and an STR. 12 Notwithstanding the fact that the number of patients studied in our review is relatively small preventing a definitive conclusion, a

the majority of the pons and are diffuse in nature with poor prognosis. This latter group, termed diffuse intrinsic brainstem glioma, remains one of the most challenging tumor types, with multiple clinical trials failing to improve survival. 7 , 9 , 11 , 12 , 15 The aim of this study was a retrospective analysis to determine whether histological grade, age, and MRI findings are prognostic factors for survival of patients with brainstem gliomas confirmed by histopathological diagnosis. Methods The study involved a retrospective evaluation of medical records

✓ A group of 356 patients who received head injuries in the Korean War during 1951–1953 have been reviewed with special concern for the prognostic indicators in posttraumatic epilepsy. Factors that operate in the occurrence of seizures after craniocerebral trauma are degree of brain destruction, length of coma, and, to a lesser extent, site of injury. None of these factors is related to the persistence of attacks once they have begun. For the latter, the most useful prognostic factors are derived from the time of onset and frequency of seizures.

and OS, respectively). As a result, univariate and multivariate analyses ( Tables 5 and 6 ) for LC, DFS, and OS, based on key surgical and adjuvant therapy prognostic factors, were performed for the entire cohort with these histologies combined. After stratification for treatment era, analysis of the treated volumes showed a significant increase in size of planning treatment volumes (PTVs) for patients treated after 2007 (increase of the median PTV subclinical dose [PTV1] by 40%, p = 0.01). The median PTV prescription dose (PTV2) increased by 18% but was not

in this age range, following astrocytoma and medulloblastoma. Most ependymomas in children occur in supratentorial or posterior fossa locations, and the prognosis for these patients remains poor, especially for young children. No clear improvement has been observed when using new postoperative treatments including intensive chemotherapy and hyperfractionated radiotherapy. 2 Although some definitive prognostic factors have emerged, such as the extent of tumor resection and the age of the patient, tumor location and histological composition and the role of adjuvant

at our institution, most of the patients present for consultation with the diagnosis of SCCM and related symptoms, which are the reasons for MR imaging. Nonetheless, a conclusive answer regarding the frequency of asymptomatic SCCM appears premature in view of the rarity of the entity. There are now a number of reports available of cases or small series of surgically managed SCCM. Most agree that the outcome is not uniformly positive. The purpose of the present update is to analyze our experience in light of prognostic factors. The main focus is on surgically

24 1973 11 In order to evaluate possible prognostic factors, the clinical course was correlated to the age of the patient; possible arterial hypertension; the red blood cell (RBC) count in the CSF during the immediate posthemorrhagic period; and the neurological findings on admission. The RBC count in CSF during the 1st or 2nd day after the SAH was available in only 90 patients. Summary of Cases Findings on Admission In direct association with the bleeding episode, eight patients lost consciousness for periods of time varying
