Mitochondrial Corrosion in the Cytoplasmic Decreasing Equivalents in the Oncoming of Oxidant Tension in the Isoproterenol-Induced Rat Myocardial Infarction.
A total of 34 studies with 598 patients were included in the qualitative synthesis. These include 23 studies of carotid atherosclerotic disease, 7 studies of cerebral aneurysms, and 4 studies of non-aneurysmal posterior circulation pathology. OCT imaging was feasible in 94% of patients with 0.6% complication rate. Endovascular OCT appears to be safe and feasible, allowing clinicians to visualize stent-vessel interactions, aneurysmal healing, and vulnerable atherosclerotic plaque features. OCT carries great promise, however additional investigations are needed before any imposing statement can be made about the role of OCT in cerebrovascular imaging.Coccidioidomycosis exposure is common in the southwest United States and northern Mexico. Dissemination to the meninges is the most severe form of progression. Although ischemic strokes are well-reported in these patients, other cerebrovascular complications of coccidioidomycosis meningitis (CM), as well as their treatment options and outcomes, have not been systematically studied. We present a uniquely severe case of CM with several cerebrovascular complications. We also systematically queried PubMed and EMBASE databases, including articles published before April 2020 reporting human patients with CM-induced cerebrovascular pathology other than ischemic infarcts. Sixteen articles met inclusion criteria, which describe 6 patients with aneurysmal hemorrhage, 10 with non-aneurysmal hemorrhage, one with vasospasm, and one with transient ischemic attacks. CM-associated aneurysms invariably presented with hemorrhage. These were universally fatal until the past decade, when advances in surgical clipping and/or combined surgical and endovascular treatment have improved outcomes. We found that non-aneurysmal intracranial hemorrhages were limited to male patients, involved a diverse set of intracranial vasculature, and had a mortality rate surpassing 80%. Vasospasm was reported once, and was treated with percutaneous transluminal angioplasty. Transient ischemic attacks were reported once, and were successfully treated with fluconazole and dexamethasone. This review suggests that CM can present with a wide array of cerebrovascular complications, including ischemic infarcts, aneurysmogenesis, non-aneurysmal intracranial hemorrhage, vasospasm, and transient ischemic attacks. Mortality has improved over time due to advances in surgical and endovascular treatment modalities. The exception is non-aneurysmal intracranial hemorrhage, which remains associated with high mortality rates and few targeted therapeutic options.The etiological agent of coronavirus disease-19 (COVID-19), SARS-coronavirus-2 (SARS-CoV-2), emerged in Wuhan, China, and quickly spread worldwide leading the World Health Organization (WHO) to recognize it not only as a pandemic but also as an important thread to public health. Beyond respiratory symptoms, new neurological manifestations are being identified such as headache, ageusia, anosmia, encephalitis or acute cerebrovascular disease. Here we report the case of an acute transverse myelitis (TM) in a patient with SARS-CoV-2 infection detected by the nasopharyngeal swab technique but not in cerebrospinal fluid (CSF) analysis. Anti-herpes simplex virus (HSV) 1 and varicella-zoster IgM antibodies were not detected in serum samples and spinal and brain magnetic resonance imaging (MRI) showed no abnormal findings. This case remarks that COVID-19 nervous system damage could be caused by immune-mediated mechanisms.The objective of this study was to elucidate the clinical features, surgical treatment, and outcome of intracranial aneurysms associated with moyamoya disease. We retrospectively reviewed a consecutive cohort of 79 moyamoya disease patients with 98 intracranial aneurysms at Beijing Tiantan Hospital. Clinical features, radiological findings, and outcomes were analyzed. Prevalence of intracranial aneurysms in patients with moyamoya disease was 3.9%. The mean age at diagnosis was 39.0 ± 12.4 years, with 1 peak distribution in patients from 40 to 50 years of age. The ratio of women to men was 1.001.03. Familial occurrence was 2.5%. The initial symptom was hemorrhage or ischemia in 56 (70.9%) and 23 patients (30.4%), respectively. Most patients presented with Suzuki stage 3 or 4. Seventy-nine cases had 98 aneurysms. Of the 98 aneurysms, sixteen aneurysms (16.3%) were treated by microsurgery and 7 by endovascular procedures, 13 aneurysms were conservatively managed, the remaining 62 were treated with revascularization alone. After a median nine-month angiographic follow-up, 18 aneurysms received clipped or embolized were completed occlusion, 18 aneurysms received conservative treated or coating were remained stable. Of the remaining 63 aneurysms that were treated with revascularization alone, 59 of 63 aneurysms remained stable, and 2 were obliterated, whereas 1 aneurysm ruptured during the follow-up. Hemorrhage was the most common symptom in intracranial aneurysms associated with moyamoya disease. Revascularization surgery may improve cerebral circulation, decreases hemodynamic stress and prevent the rupture of intracranial aneurysms.
Chordoid gliomas (CGs) are rare neuroepithelial tumors, which commonly arise from the anterior part of the third ventricle. Most studies on CGs included only one or two cases. TRAM-34 To better understand the disease, we report 14 patients with pathologically confirmed CGs.

The clinical characteristics, including radiological and histological examination, operative records, and prognoses were analyzed and reviewed.

The case series included six male and eight female patients with an average age of 44.4years. The most common preoperative symptom was headache (64.3%) and visual deterioration (57.1%). Radiological results showed that the third ventricle (12/14) was the most common site of the brain involved, and the lesions presented with solid (n=9, 64.3%) or cystic-solid (n=5, 35.7%) appearance. All patients were misdiagnosed as non-CG tumors. The operation approach was mainly determined by tumor location, thus trans-callosal approach (9/14) and trans-laminar terminalis approach were commonly used. Gross total resection (GTR) was achieved in all cases and none of them received any adjuvant therapy postoperatively.
