Purpose: The management of tandem extracranial internal carotid artery and intracranial large vessel occlusion during endovascular thrombectomy (EVT) for acute ischemic stroke (AIS) has been under-investigated. We sought to investigate outcomes of AIS patients with tandem occlusion (TO) treated with carotid artery stenting (CAS) compared to those not treated with CAS (no-CAS) during EVT., Methods: We performed a cohort study using data from AIS patients enrolled in the Italian Registry of Endovascular Treatment in Acute Stroke. Outcomes were 3 months' mortality, functional outcome, complete and successful recanalization, any intracranial hemorrhage, parenchymal hematoma and symptomatic intracerebral hemorrhage., Results: Among 466 AIS patients with TO, CAS patients were 122 and no-CAS patients were 226 (118 excluded). After adjustment for unbalanced variables, CAS was associated with a lower rate of 3 months' mortality (OR 0.407, 95% CI 0.171-0.969, p = 0.042). After adjustment for pre-defined variables, CAS was associated with a lower rate of 3 months' mortality (aOR 0.430, 95% CI 0.187-0.989, p = 0.047) and a higher rate of complete recanalization (aOR 1.986, 95% CI 1.121-3.518, p = 0.019), successful recanalization (aOR 2.433, 95% CI 1.263-4.686, p = 0.008) and parenchymal hematoma (aOR 2.876, 95% CI 1.173-7.050, p = 0.021). CAS was associated with lower 3 months mortality (OR 0.373, 95% CI 0.141-0.982, p = 0.046) and higher rates of successful recanalization (OR 2.082, 95% CI 1.099-3.942, p = 0.024) after adjustment for variables associated with 3 months' mortality and successful recanalization, respectively., Conclusions: Among AIS patients with TO, CAS during EVT was associated with a higher rate of successful reperfusion and a lower rate of 3 months' mortality., (© 2022.

Psychometric performance has been reported to be related to brain atrophy in cirrhotics, but the relationship between brain atrophy and EEG findings is still unknown. The aim of this study was to ascertain the relationship among brain atrophy, EEG, and cognitive performance in cirrhotics. Sixty-eight cirrhotics (age = 55 +/- 10 years; males-66%) underwent psychometric evaluation (Symbol Digit Test, Trail Making Test-Part A, Scan test), EEG recording and spectral analysis (S-EEG), and brain CT scan. Central brain atrophy was ascertained by the following indexes of brain atrophy: the Evans' index, the bicaudate index, the cella media index, the bifrontal index, and the ventricular index; cortical brain atrophy by the sulci index. The severity of liver failure was assessed by the Child-Pugh score: 18% of patients were Child-Pugh Class A, 50% Class B, and 32% Class C. Central and cortical atrophies were found to be correlated with age, but not with the Child-Pugh score. Psychometric performance and the EEG mean dominant frequency (MDF) were found to be correlated with brain atrophy. Multivariate analysis showed that a poor psychometric performance was independently predicted by EEG slowing (MDF: p < 0.01) and by central brain atrophy (cella media index: p < 0.01). In conclusion, brain atrophy was associated with a poor psychometric performance and EEG alterations in cirrhosis. Both brain atrophy and EEG alterations independently predicted cognitive dysfunction in cirrhotic patients.

Purpose: The poor results from treatment of high grade glioma prompted us to explore new protocols involving concurrent radio-chemotherapy. Our primary objective was to evaluate the feasibility of very early postoperative chemotherapy with BCNU, concurrent radio-chemotherapy with carboplatin and teniposide, and post-radiotherapy BCNU. Our secondary objectives were to evaluate time to progression, and overall survival., Patients and Methods: We treated 24 newly diagnosed patients (pts) with BCNU 150 mg/m2 seven days after surgery. Thirty days later, we started radiotherapy, 1.8 to 2 Gy/day for 5 days a week on limited fields up to 60 Gy, and concurrent chemotherapy with carboplatin 250 mg/m2 on days 1, 22, and 43, and teniposide 50 mg/m2 on days 1, 2, 3, 22, 23, 24, 43, 44 and 45. Two cycles of 150 mg/m2 BCNU were then given at 30 and 70 days, respectively, after the end of the radio-chemotherapy course. Therapy was then suspended, but if disease progression was evident, treatment was resumed with drugs that had not been previously employed. Surgical reintervention was not routinely considered., Results: Following radio-chemotherapy treatment in the 24 pts evaluable for response, we observed partial remissions in 8 cases (33%) and stable disease in 12 (50%). Actuarial estimates of progression free survival (PFS) were 33 weeks, with 56 wks for anaplastic astrocytoma and 31 weeks for glioblastoma. Median survival time (MST) of all pts was 58 weeks; 51 weeks for glioblastoma and was not reached for anaplastic astrocytoma. This regimen was feasible. Of 144 planned cycles, 139 were delivered, and among these only in 13 and 9 cycles the doses were reduced by 75 and 50%, respectively. We did not observe any gastrointestinal toxicity. Grade 2 hematological toxicity occurred in 25% of pts. grade 3 in 4% and neurological toxicity in 3% of the pts during BCNU delivery, probably due to a sharp increase in intracranial pressure., Conclusion: Early chemotherapy, concurrent chemo-radiotherapy and brief post-radio-therapy chemotherapy are feasible and well tolerated. The objective response and disease stabilization rates appear similar to previous experiences.
