Thirteen patients (34.2%) underwent either another operation due to the lack of resolution of their AC-related symptoms or secondary to complications directly related to their initial surgery. Average length of followup from time of first operation was 84.1 months. Overall, our results demonstrate similarities in epidemiology, clinical presentation and surgical experience, in comparison to larger cohort studies. We advocate collaborative efforts to better understanding of the pathophysiology of paediatric ACs, particularly for deciding between the various surgical treatment modalities.
Grade 3 gliomas are aggressive primary brain tumors. Promoter methylation of methyl guanine methyl transferase (MGMT) has been associated with a favorable prognosis in patients with glioblastoma, but the impact of MGMT promoter methylation in patients with grade 3 gliomas is less clear. The purpose of the present study was to evaluate the utilization of MGMT testing in patients with Grade 3 glioma, as well its prognostic and predictive value.

The National Cancer Database (NCDB) was queried (2004-2016) for patients with newly diagnosed grade 3 glioma without 1p19q codeletion. Statistics included Kaplan-Meier overall survival (OS) analysis, along with Cox proportional hazards modeling.

Of 20,488 total patients, 1,209 (5.0%) had MGMT testing. Of these patients, 561 (46.4%) were MGMT methylated (mMGMT), and 648 (53.6%) were MGMT unmethylated (uMGMT). mMGMT patients experienced greater median overall survival (OS) than both uMGMT patients as well as patients with no MGMT status reported (p<0.05 for both).T, though there was no difference in overall survival observes amongst patients receiving adjuvant chemotherapy or those patients receiving no adjuvant treatment. The study also found that only 5% of patients nationwide with Grade 3 Glioma are tested for MGMT.
The present study is the largest of its kind to examine the prognostic and predictive impact of MGMT methylation (mMGMT) amongst patients with Grade 3 Glioma. The results suggest that mMGMT is prognostic, as amongst all patients, mMGMT was associated with improved overall survival. These results also suggest that mMGMT is predictive, as patients treated with adjuvant chemoradiation or adjuvant radiation therapy did have improved overall survival with mMGMT, though there was no difference in overall survival observes amongst patients receiving adjuvant chemotherapy or those patients receiving no adjuvant treatment. The study also found that only 5% of patients nationwide with Grade 3 Glioma are tested for MGMT.In patients with aneurysmal subarachnoid hemorrhage (aSAH) unfavorable for endovascular or traditional open surgical techniques, surgical revascularization strategies comprise one of remaining limited options. There is nonetheless a paucity of data on the safety and efficacy of bypass in aSAH. In this study, we aimed to investigate complications and outcomes in a cohort of patients with aSAH treated with bypass. A prospective single-surgeon database of consecutive patients treated for aSAH between 2013 and 2018 was retrospectively analyzed. Selleckchem Abivertinib Complications and functional status at discharge were recorded and analyzed for the patients that underwent bypass surgery. Forty patients with aSAH were treated with bypass surgery (23 extracranial-intracranial; 17 intracranial-intracranial). All-cause perioperative mortality was 13% (6 patients). At discharge and at mean 14-month follow up, respectively, 16/40 (40%) and 16/25 (64%) of patients achieved a Glasgow Outcome Score of 4-5. All-cause, in-hospital complications occurred in 28 patients (70%), of which any ischemic complication occurred in 20 patients (50%), 7 (18%) being open surgical complications. This work represents the largest modern series of bypass for aSAH to date. In cases of aSAH unfavorable for endovascular intervention or traditional open surgical techniques, bypass remains a viable option in this complex group of patients.Dosing of recombinant tissue plasminogen activator (rt-PA) for acute ischemic stroke treatment is often based on estimated body weight (BW) worldwide in routine clinical practice due to infeasible of accurate BW measurement. The aim of our study is to explore the impact of estimated BW when dosing rt-PA in acute ischemic stroke treatment on clinical outcome. Between January 2013 to May 2018, 126 acute ischemic stroke patients received intravenous rt-PA treatment based on estimated BW dosage were recruited. All patients had actual BW measured in ward after treatment. Based on the dosage of rt-PA given, patients were categorized into three groups, standard dose (0.8-1.0 mg/kg), overdose (>1.0 mg/kg), and underdose ( less then 0.8 mg/kg). Among all 126 patients, 101 (80.2%) patients were treated with standard dose, 12 (9.5%) patients with overdose, and 13 (10.3%) patients with underdose of rt-PA respectively. There was no significant difference between demographic characteristics, pre-morbid risk factors, National Institutes of Health Stroke Scale (NIHSS) score at 24 h, NIHSS score at discharge, modified Rankin scale (mRS) within 0 to 2 in discharge or in 3 months after the event within the three groups. There was also no significant difference in hemorrhagic transformation and symptomatic intracranial hemorrhage (SICH). In conclusion, calculation of the dose of rt-PA based upon the estimated BW to treat acute ischemic stroke patients had no negative impact on the clinical outcome in our study.
During the coronavirus 19 (COVID-19) pandemic, physicians have begun adapting their daily practices to prevent transmissions. In this study we aimed to provide surgical neuro-oncologists with practice guidelines during the COVID-19 pandemic based on objective data from a high-volume brain tumor surgeon at the current COVID-19 epicenter.

All outpatient visits and surgeries performed by the senior author during the COVID-19 pandemic were compared between the initial quarantine (3/23/20-5/4/20), the plateau period following quarantine (5/5/20-6/27/20), and the second peak (6/28/20-7/20/20). In-person and telemedicine visits were evaluated for crossovers. Surgeries were subdivided based on lesion type and evaluated across the same time period.

From 3/23/20-7/20/20, 469 clinic visits and 196 surgeries were identified. After quarantine was lifted, face-to-face visits increased (P<0.01) yet no change in telehealth visits occurred. Of 327 telehealth visits, only 5.8% converted to in-person during the 4-month period with the most cited reason being patient preference (68.
