Background: This study sought to examine health-related quality of life several years after spontaneous nontraumatic subarachnoid hemorrhage. Recent studies report impairments to be improved as far as normal levels. We question such an improvement in our own patient population over a period of 10 years. Methods: The Medical Outcomes Study 36-Item and Medical Outcomes Study 12-Item Short-Form Health Surveys on health-related quality of life were used to question 236 patients and 235 proxies. The patients were assigned to 5 groups according to the time that had elapsed since their hemorrhage: 1 year N = 22, 2 years N = 36, 5 years N = 86, 8 years N = 61, and 10 years N = 31. Analyses of variance (ANOVA, Kruskal-Wallis) and correlation (Spearman, Kendall tau) were used in an exploratory approach. Significance was established as P ≤ 0.05. Results: Over a period of 10 years, health-related quality of life is found to be impaired, and is reported as such by the patients themselves and their proxies. Comparison of the mean values between the groups, ie, 1, 2, 5, and 10 years, revealed no significant differences in health-related quality of life. The calculations with a view to correlations between the group means and time since hemorrhage also produced only very weak correlations of no significance. Conclusions: Health-related quality of life is impaired over a period of 10 years. Spontaneous nontraumatic subarachnoid hemorrhage should be regarded as a chronic cerebrovascular condition. © 2014 Elsevier Inc. Source


At present, modern skull base surgery is a highly sophisticated interdisciplinary collaboration of various diagnostic and therapeutic disciplines. The overall goal is the treatment of complex tumorous, traumatic, vascular and inflammatory processes or developmental disorders of the skull base with preservation of function. The paper presents modern concepts, procedures and minimally invasive strategies in skull base surgery and also critically discusses the current trend to endoscopic and robot-assisted surgical techniques. © 2011 Springer-Verlag.

Context: Pegvisomant is a GH receptor antagonist. The ACROSTUDY is a global safety surveillance study of long-term treatment of acromegaly with pegvisomant. Objective: The objective of the study was to monitor long-term safety and treatment outcomes. Design: ACROSTUDY is open to all patients with acromegaly who are treated with pegvisomant. We report an interim analysis of data captured from 1288 subjects enrolled before a database freeze of December 31, 2009. Setting: This was a global noninterventional surveillance study. Main Outcome Measure(s): Long-term monitoring of safety, including central magnetic resonance imaging (MRI) reading and treatment outcomes, was measured. Results: Subjects (n = 1288) were treated with pegvisomant for a mean of 3.7 yr and followed up in ACROSTUDY for a mean of 2.1 yr. A total of 1147 adverse events (AE) were recorded in 477 subjects (37%), among which 192AEin 124subjects (9.6%) were considered to be related to pegvisomant. Serious AE were recorded in 159 subjects (12.3%), whereas pegvisomant-related Serious AE were recorded in 26 subjects (2%). No deaths (15 subjects; 1.2%) were attributed to pegvisomant use. The incidence of increase in pituitary tumor size in the subset with confirmed MRI increases on central reading represented 3.2% of the overall cohort with at least two available MRI (n = 936). Injection-site reactions were reported in 28 cases (2.2%). In 30 patients (2.5%), an elevated aspartate aminotransferase or alanine aminotransferase of more than 3 times the upper level of normality was reported. There were no reports of liver failure. After 5 yr of pegvisomant treatment, 63.2% of subjects had normal IGF-I levels at a mean dose of 18 mg/d. Conclusions: Data entered and evaluated in ACROSTUDY indicate that pegvisomant is an effective and safe medical treatment in patients with acromegaly. The reported low incidence of pituitary tumorsize increase, liver enzyme elevations, and lipodystrophy at the injection site are reassuring. Copyright © 2012 by The Endocrine Society. Source

Introduction: The purpose of this study was to evaluate the safety and efficacy of the recently available flow diverter "pipeline embolization device" (PED) for the treatment of intracranial aneurysms and dissections. Methods: Eighty-eight consecutive patients underwent an endovascular treatment of 101 intracranial aneurysms or dissections using the PED between September 2009 and January 2011. The targeted vessels include 79 (78%) in the anterior circulation and 22 (22%) in the posterior circulation. We treated 96 aneurysms and 5 vessel dissections. Multiple devices were implanted in 67 lesions (66%). Results: One technical failure of the procedure was encountered. Immediate exclusion of the target lesion was not observed. Angiographic follow-up examinations were carried out in 80 patients (91%) with 90 lesions and revealed complete cure of the target lesion(s) in 47 (52%), morphological improvement in 32 lesions (36%), and no improvement in 11 lesions (12%). Six major complications were encountered: one fatal aneurysm rupture, one acute and one delayed PED thrombosis, and three hemorrhages in the dependent brain parenchyma. Conclusion: Our experience reveals that the PED procedure is technically straightforward for the treatment of selected wide-necked saccular aneurysms, fusiform aneurysms, remnants of aneurysms, aneurysms with a high likelihood of failure with conventional endovascular techniques, and dissected vessels. While vessel reconstruction, performed after dissection, is achieved within days, remodeling of aneurysmal dilatations may take several months. Dual platelet inhibition is obligatory. Parenchymal bleeding into brain areas dependent on the target vessel is uncommon. © The Author(s) 2011. Source

Five-aminolevulinic-acid (5-ALA) is known for its benefits in surgery of primary gliomas, but has only been cautiously used in recurrent gliomas dreading over-resection, insufficient or false-positive fluorescence in adjuvantly treated tumors. We evaluated intraoperative fluorescence based on tumor pathology, pretreatment as well as surgical and neurological outcome in patients with recurrent gliomas. Patients who underwent fluorescence-guided surgery for recurrent gliomas between 6/2010 and 2/2014 at our institution were retrospectively selected. Degree of surgical resection, neurological status, pathology results, intraoperative fluorescence and follow up status were analyzed. Patients who underwent repeat surgery without 5-ALA were selected as controls. 58 patients with high grade gliomas (°III and °IV) were included. 10 of 63 tumors (15.9 %) failed to fluoresce intraoperatively of which nine (90 %) had been adjuvantly treated prior to recurrence, as were 46 of the 53 fluorescing tumors (86.8 %). Non-fluorescing tumors were IDH mutated significantly more often (p = 0.005). 30 tumors (47.6 %) were located eloquently. 51 (80.9 %) patients showed no new neurologic deficits postoperatively. 13 patients (20.6 %) showed no signs of recurrence at their latest follow up. Eight patients were lost to follow up. Overall survival was significantly longer in the 5-ALA group (p = 0.025). Fluorescence-guided surgery in recurrent gliomas is safe and allows for a good surgical and neurological outcome in a difficult surgical environment, especially when used in combination with neuronavigation and intraoperative ultrasound to prevent over-resection. Adjuvant therapy did not significantly influence fluorescing properties. © 2015, Springer Science+Business Media New York. Source
