Validation of the Subjective Handicap of Epilepsy (SHE) in Brazilian patients with epilepsy

The objectives of the study were to translate and adapt the Subjective Handicap of Epilepsy (SHE) instrument to Brazilian Portuguese and to determine its psychometric properties for the evaluation of quality of life in patients with epilepsy. A sample of 448 adult patients with epilepsy with different clinical profiles (investigation, preoperative period, postoperative period, and drug treatment follow-up) was evaluated with the SHE and the Epilepsy Surgery Inventory (ESI-55). Exploratory factorial analysis demonstrated that four factors explained 60.47% of the variance and were sensitive to discriminate the different clinical groups, with the preoperative group having the poorest quality of life. Internal consistency ranged from 0.92 to 0.96, and concurrent validity with the ESI-55 was moderate/strong (0.32-0.70). Test-retest reliability was confirmed, with an ICC value of 0.54 (2 days), 0.91 (7 days), and 0.97 (30 days). The SHE had satisfactory psychometric qualities for use in the Brazilian population, similar to those of the original version. The instrument seems to be more adequate in psychometric terms for the postoperative and drug treatment follow-up groups, and its use should be encouraged. (c) 2012 Elsevier Inc. All rights reserved

Differential aberrant sprouting in temporal lobe epilepsy with psychiatric co-morbidities

Psychiatric co-morbidities in epilepsy are common in patients with temporal lobe epilepsy (TLE). Pathological alterations in TLE are well characterised; however, neuropathologic data are relatively scale regarding the association between psychiatric diseases and epilepsy. Our objective was to evaluate the clinical data of 46 adult TLE patients with and without psychiatric co-morbidities and to correlate the data with hippocampal neuronal density and mossy fiber sprouting. Accordingly, patients were grouped as follows: TLE patients without history of psychiatric disorder (TLE, n = 16), TLE patients with interictal psychosis (TLE + P, n = 14), and TLE patients with major depression (TLE + D, n = 16). Hippocampi from autopsies served as non-epileptic controls (n = 10). TLE + P exhibited significantly diminished mossy fiber sprouting and decreased neuronal density in the entorhinal cortex when compared with TLE. TLE + P showed significantly poorer results in verbal memory tasks. TLE + D exhibited significantly increased mossy fiber sprouting length when compared with TLE and TLE + P. Further, a higher proportion of TLE + D and TLE + P presented secondarily generalised seizures than did TLE. Our results indicate that TLE patients with psychiatric disorders have distinct features when compared with TLE patients without psychiatric co-morbidities and that these changes may be involved in either the manifestation or the maintenance of psychiatric co-morbidities in epilepsy.

Tentorial meningiomas: follow-up review

Tentorial meningiomas comprise 3-5% of the intracranial meningiomas. Different locations and sinus invasion require special surgical skills. This study aimed to analyze factors influencing the outcome of 29 patients (30 tumors) with tentorial meningiomas surgically treated. The study included 22 female and seven male patients, with age of 18-76 years old, and a follow-up of 6-179 months. Eight tumors were located on the inner tentorial ring, 15 on the outer ring, four were falcotentorial, and three attached/invading the torcula. Outcome was analyzed using survival and recurrence-free survival (RFS) curves. Twenty-seven tumors were WHO grade I and three were grades II-III. Total and subtotal resections were reached in 87.5% and 12.5% of tumors. Survival was better for patients with grade I tumors and similar according to sex, location, size, and extent of resection. Recurrence/regrowing rate was 12.5%. RFS curves were better for patients with grade I or with radical resection and similar according to sex, location, and size. There was no operative mortality. Permanent postoperative cranial nerve deficits occurred in 9.7% (all inner ring tumors). Despite being many times large-sized, surgical treatment of tentorial meningiomas gives good results. Prognostic factors for recurrence were histopathologic grade III and subtotal resection. Radical resection allowed better results. Nevertheless, subtotal resection may be acceptable for cases with cranial nerves or sinuses invasions
