Near-pure lung adenocarcinoma (ADC) subtypes demonstrate strong stratification of radiomic values, providing basic information for pathological subtyping. We sought to predict the presence of high-grade (micropapillary and solid) components in lung ADCs using quantitative image analysis with near-pure radiomic values.

Overall, 103 patients with lung ADCs of various histological subtypes were enrolled for 10-repetition, 3-fold cross-validation (cohort 1); 55 were enrolled for testing (cohort 2). Histogram and textural features on computed tomography (CT) images were assessed based on the "near-pure" pathological subtype data. Patch-wise high-grade likelihood prediction was performed for each voxel within the tumour region. The presence of high-grade components was then determined based on a volume percentage threshold of the high-grade likelihood area. To compare with quantitative approaches, consolidation/tumour (C/T) ratio was evaluated on CT images; we applied radiological invasiveness (C/T ratio > 0• Using near-pure radiomic features and patch-wise image analysis, high-grade components of lung adenocarcinoma can be predicted with high sensitivity and moderate specificity. • Using near-pure radiomic features and patch-wise image analysis has potential role in facilitating the prediction of the presence of high-grade components in lung adenocarcinoma prior to surgical resection.

ON is frequently misdiagnosed in the clinical arena, leading to either inappropriate management or diagnostic delays. As a result, patients may fail to achieve optimal recovery. The treatment response to corticosteroids and long term risk of multiple sclerosis was established in the first clinical trials conducted roughly 30 years ago. Spontaneous resolution was observed in the vast majority of patients and intravenous high-dose corticosteroids hastened recovery; half of the patients eventually developed multiple sclerosis. Over the ensuing decades, the number of inflammatory conditions associated with ON has significantly expanded exposing substantial variability in the prognosis, treatment, and management of ON patients. ON subtypes can frequently be distinguished by distinct clinical, serological, and radiological profiles allowing expedited and specialized treatment. Guided by an increased understanding of the immunopathology underlying optic nerve and associated CNS injuries, novel disease management strategies are emerging to minimize vision loss, improve long-term surveillance strategies, and minimize CNS injury and disability. Knowledge regarding the clinical signs and symptoms of different ON subtypes is essential to guide acute therapy, prognosticate recovery, accurately identify underlying CNS inflammatory disorders, and facilitate study design for the next generation of clinical and translational trials.
Superficial siderosis of the central nervous system is a rare intractable disease induced by chronic subarachnoid hemorrhage. Neurological deficits, such as cerebellar ataxia and hearing difficulties, gradually progress if left undiagnosed. Hemosiderin deposition is irreversible because standard medical treatment has not yet been established. Interventions at the source of bleeding may be the key to a preferable outcome of treatment for chronic subarachnoid hemorrhage; however, the source is not clear in many cases.

Among the consecutive cases diagnosed with a spontaneous cerebrospinal fluid (CSF) leak, cases of superficial siderosis associated with a CSF leak due to a ventral dural defect were retrospectively analyzed.

Among 77 cases of a CSF leak, 7 cases (9%) of superficial siderosis were identified (median age of 59years, male, 4 cases). Defects were diagnosed on 1-mm sliced fast imaging employing steady-state acquisition MRI (n = 5), conventional myelographic CT (n = 1), or dynamic myelographic CT (n = 1) at high thoracic levels (T1-T4). All defects were repaired by direct neurosurgery. During surgery, continuous bleeding from the epidural veins of the internal vertebral venous plexus was identified as the source of subarachnoid hemorrhage. Epidural CSF pulsations through the defect prevented clot formation by the epidural veins. Dural repair stopped free communication between the subarachnoid and epidural spaces, leading to the disappearance of chronic subarachnoid hemorrhage.

Bleeding from the epidural venous plexus may be the cause of superficial siderosis associated with ventral dural defects. Neurosurgical repair may stop the progression of this condition.

The significance of neutrophil-to-lymphocyte ratio (NLR) has been explored in different diseases. Few studies addressed its role in patients with multiple sclerosis (MS), with promising results regarding its association with disease activity or disability.

We aimed at confirming the role of NLR as a marker of neuro-inflammation in a cohort of newly diagnosed MS and clinically isolated syndrome (CIS) patients. Furthermore, we compared the validity of NLR with established markers of neuro-inflammation, such as serum neurofilament light chain (Nfl), CSF microvesicles (CSF-MVs) and CSF IgG indices.

We retrospectively selected, from a prospectively collected cohort of newly diagnosed MS/CIS patients hospitalized for diagnostic work-up, 121 patients who underwent CSF examination, brain MRI and blood cell count within the time of hospitalization and did not receive steroid treatment before sample collection. Patients were grouped according to presence of gadolinium enhancement at brain MRI.

No association was found between NLR and disease activity, nor with other clinical measures. Nfl, CSF-MVs, Link and Tourtellotte indices were significantly higher in patients with brain MRI activity.

Our negative results do not support the use of NLR as a marker of disease activity and disability in patients with MS.

Current assays include in-house immunochemistry (IHC), or cell-based assays (CBA) which use live (L-CBA) or fixed cells (F-CBA), and commercially available fixed-cells CBA (C-CBA), but these have not been compared in parallel. We compared the L-CBA with F-CBA, C-CBA, and IHC using sera and CSFs archived from > 30,000 received for testing and previously positive by L-CBA. Referring neurologists, if identified, provided "definite" or "unlikely" diagnoses of NMDAR-Ab encephalitis for 31 paired serum-CSF samples and 53 unpaired sera. There was good concordance between paired sera and CSFs, with 13/16 "definite" pairs positive, and 7/8 "unlikely" pairs negative in all in-house assays. In unpaired "definite" sera, L-CBA was most sensitive. However, 19/24 serum samples from "unlikely" patients were positive by L-CBA, with only 5/24 and 1/24 positive by F-CBA and IHC, respectively. In available samples, C-CBA demonstrated high sensitivity for CSF, but surprisingly low sensitivity for serum. Overall, regardless of the technique, CSF results were accurate and easy to interpret, but if CSF is unavailable, negative serum C-CBA results in cases with suspected NMDAR-Ab encephalitis could be repeated by a more sensitive in-house assay. Although these assays are sensitive, particularly for CSF, referral of sera with low pre-test probability should be avoided to reduce clinically-irrelevant "false positive" results.
Symptomatic intracerebral hemorrhage (sICH) is a common complication of acute ischemic stroke (AIS) associated with limited treatments and poor outcomes. We aimed to identify predictive factors of sICH in patients with AIS following mechanical thrombectomy (MT) in a real-world setting.

Patients with large vessel occlusion of the anterior circulation treated with MT were consecutively included in a prospective monocentric cohort. Clinical, biological, and radiological parameters were collected to identify pre-procedural predictors for sICH.

637 patients were included in our study. Magnetic resonance imaging was performed on most patients (86.7%). sICH occurred in 55 patients (8.6%). 428 patients (67.2%) were treated with intravenous thrombolysis. After multivariate analysis, prior use of antiplatelet therapies (odd ratio (OR) 1.84, 95% confidence interval (CI) 1.01-3.32), high C-reactive protein (OR per standard deviation (SD) increase 1.28, 95% 1.01-1.63), elevated mean arterial blood pressure (OR per 10mmHg increase 1.22, 95% CI 1.03-1.44), hyperglycemia (OR per one SD-log increase 1.38, 95% CI 1.02-1.87), and low ASPECTS (OR per 1-point decrease 1.42, 95% CI 1.12-1.80) were found to be independent predictive factors of sICH. The pre-procedural predictors did not change when the absence of successful recanalization was considered as a covariate. Patients with strokes of unknown onset time were not especially vulnerable for sICH.

sICH after MT was associated with several pre-procedural risk factors prior use of antiplatelet therapies, high C-reactive protein and hyperglycemia at baseline, elevated mean arterial blood pressure, and low ASPECTS.

Prompt treatment of Bell's palsy is critical in order for patients to achieve complete recovery of facial function. Delays in diagnosis and management can result in permanent facial defects. A number of clinical practice guidelines (CPG) exist to guide clinical decision-making in patients presenting with idiopathic facial paralysis. However, to date, there has been no comprehensive review of the methodological rigor and quality of these CPGs. Thus, the objective of the authors is to appraise the existing CPGs to ensure safe and effective practices. A total of eight guidelines met the inclusion criteria and were appraised. Only two CPGs achieved an overall rating of 'High', having five or more quality domains scoring > 60%. Across the CPGs, the domains of rigor of development, stakeholder involvement, and applicability has the lowest overall scores with 48.
