Abstract
Background and purpose Neurological manifestations in coronavirus disease (COVID)‐2019 may adversely affect clinical outcomes. Severe COVID‐19 and uremia are risk factors for neurological complications. However, the lack of insight into their pathogenesis, particularly with respect to the role of the cytokine release syndrome (CRS), is currently hampering effective therapeutic interventions. The aims of this study were to describe the neurological manifestations of patients with COVID‐19 and to gain pathophysiological insights with respect to CRS. Methods In this longitudinal study, we performed extensive clinical, laboratory and imaging phenotyping in five patients admitted to our renal unit. Results Neurological presentation included confusion, tremor, cerebellar ataxia, behavioral alterations, aphasia, pyramidal syndrome, coma, cranial nerve palsy, dysautonomia, and central hypothyroidism. Notably, neurological disturbances were accompanied by laboratory evidence of CRS. Severe acute respiratory syndrome coronavirus‐2 (SARS‐CoV‐2) was undetectable in the cerebrospinal fluid (CSF). Hyperalbuminorrachia and increased levels of the astroglial protein S100B were suggestive of blood−brain barrier (BBB) dysfunction. Brain magnetic resonance imaging findings comprised evidence of acute leukoencephalitis (n = 3, one of whom had a hemorrhagic form), cytotoxic edema mimicking ischaemic stroke (n = 1), or normal results (n = 2). Treatment with corticosteroids and/or intravenous immunoglobulins was attempted, resulting in rapid recovery from neurological disturbances in two cases. SARS‐CoV2 was undetectable in 88 of the 90 patients with COVID‐19 who underwent Reverse Transcription‐PCR testing of CSF. Conclusions Patients with COVID‐19 can develop neurological manifestations that share clinical, laboratory and imaging similarities with those of chimeric antigen receptor T‐cell‐related encephalopathy. The pathophysiological underpinnings appear to involve CRS, endothelial activation, BBB dysfunction, and immune‐mediated mechanisms.

Abstract
Complete resection of brain arteriovenous malformation (AVM) is a surgical challenge, mainly due to risk of intraoperative rupture. The objective of this feasibility study was to analyze complete resection rate at 3 months and clinical outcome at 6 months after treatment of brain AVM by combined single-stage embolization and surgical resection. A retrospective observational study from July 2015 to February 2019 was conducted at the Department of Neurosurgery of Strasbourg University Hospital, France. Decision to treat was taken on the basis of history of AVM rupture, symptomatic AVM, or morphologic risk factors for rupture. Complete resection rate was assessed on postoperative cerebral subtraction angiography at 3 months and clinical outcome at 6 months was evaluated on the modified Rankin Scale (mRS). In the 16 patients treated for symptomatic brain AVM, the rate of complete resection was 75%, resection with residual shunt 18.7%, and incomplete resection with residual nidus 6.3%. Good clinical outcome (mRS=0 or 1) was achieved in 81.3% of patients at 6 months. The transfusion rate was 7.1%. There were procedural complications in 12.5% of patients but no intraoperative ruptures. This combined single-stage procedure allows extensive preoperative embolization of the AVM, facilitating surgical microdissection by identifying the dissection plane and perforating arteries and allowing the operator to work in close contact with the nidus without fear of intraoperative rupture.

Abstract
BACKGROUND AND PURPOSE Multinodular and vacuolating neuronal tumor (MVNT) of the cerebrum is a rare brain lesion with suggestive imaging features. The aim of our study was to report the largest series of MVNTs so far and to evaluate the utility of advanced multiparametric magnetic resonance (MR) techniques. METHODS This multicenter retrospective study was approved by our institutional research ethics board. From July 2014 to May 2019, two radiologists read in consensus the MR examinations of patients presenting with a lesion suggestive of an MVNT. They analyzed the lesions' MR characteristics on structural images and advanced multiparametric MR imaging. RESULTS A total of 64 patients (29 women and 35 men, mean age 44.2 ± 15.1 years) from 25 centers were included. Lesions were all hyperintense on fluid-attenuated inversion recovery and T2-weighted imaging without post-contrast enhancement. The median relative apparent diffusion coefficient on diffusion-weighted imaging was 1.13 [interquartile range (IQR), 0.2]. Perfusion-weighted imaging showed no increase in perfusion, with a relative cerebral blood volume of 1.02 (IQR, 0.05) and a relative cerebral blood flow of 1.01 (IQR, 0.08). MR spectroscopy showed no abnormal peaks. Median follow-up was 2 (IQR, 1.2) years, without any changes in size. CONCLUSIONS A comprehensive characterization protocol including advanced multiparametric magnetic resonance imaging sequences showed no imaging patterns suggestive of malignancy in MVNTs. It might be useful to better characterize MVNTs.

Abstract
Multinodular and vacuolating neuronal tumor of the cerebrum is a rare supratentorial brain tumor described for the first time in 2013. Here, we report 11 cases of infratentorial lesions showing similar striking imaging features consisting of a cluster of low T1-weighted imaging and high T2-FLAIR signal intensity nodules, which we referred to as multinodular and vacuolating posterior fossa lesions of unknown significance. No relationship was found between the location of the lesion and clinical symptoms. A T2-FLAIR hypointense central dot sign was present in images of 9/11 (82%) patients. Cortical involvement was present in 2/11 (18%) of patients. Only 1 nodule of 1 multinodular and vacuolating posterior fossa lesion of unknown significance showed enhancement on postcontrast T1WI. DWI, SWI, MRS, and PWI showed no malignant pattern. Lesions did not change in size or signal during a median follow-up of 3 years, suggesting that multinodular and vacuolating posterior fossa lesions of unknown significance are benign malformative lesions that do not require surgical intervention or removal.

Abstract
BACKGROUND AND PURPOSE Magnetic resonance imaging is part of the diagnostic criteria for Alzheimer's disease (AD) through the evaluation of hippocampal atrophy. The objective of this study was to evaluate which sequence of T1-weighted (T1WI) and T2-weighted (T2WI) imaging allowed the best visual evaluation of hippocampal atrophy. METHODS Visual qualitative ratings of the hippocampus of 100 patients with mild cognitive impairment (MCI) and 50 patients with AD were made independently by four operators according to the medial temporal lobe atrophy score based either on T1WI or T2WI. These two evaluations were compared in terms of interobserver reproducibility, concordance with a quantitative volumetric measure, discrimination power between AD and MCI groups, and correlation with several neuropsychological tests. RESULTS The medial temporal lobe atrophy score evaluated on either T1WI or T2WI exhibited similar interobserver variability and accordance with quantitative volumetric evaluation. However, the visual evaluation on T2WI seemed to provide better discrimination power between AD and MCI groups for both left (T1WI, P = 0.0001; T2WI, P = 7.072 × 10-5 ) and right (T1WI, P = 0.008; T2WI, P = 0.001) hippocampus, and a higher overall correlation with neuropsychological tests. CONCLUSIONS The present study suggests that T2WI provides a more adequate visual rating of hippocampal atrophy.

Abstract
BACKGROUND An isolated rupture of the alar ligament is a rare occurrence with only a few cases reported in the literature. CASE REPORT The objective was to report the case of a young man with a unilateral rupture of the alar ligament that we closely monitored, clinically and radiologically, in order to describe the evolution of the alar ligament lesions. CONCLUSION Radiological diagnosis using cervical MRI and duration of the conservative treatment remain debated and we proposed a close radiological follow-up in order to best understand the nature of these ligament lesions and their evolution following specific treatment.

Abstract
Garlic (Allium sativum L.) is one of the most important Allium spp. plants that are widely cultivated throughout the world. A significant reduction in yield and quality due to virus infection is now a serious economic problem (1). In many cases, garlic plants are infected with a variety of viruses, but elimination of these viruses is difficult because this crop is propagated through bulbs. Potyviruses, carlaviruses, and allexiviruses have been detected in diseased garlic. Onion yellow dwarf virus (OYDV) and Leek Yellow Stripe Virus (LYSV), genus Potyvirus, family Potyviridae, are two important viral pathogens of garlic. Virus diseases of garlic are widespread in the world, causing serious damage to yields and quality of the crop. The East Mediterranean Region produces 14% of the garlic production of Turkey (110,000 t). A survey was done in garlic fields in Adana, Mersin, Kahramanmaras, Hatay, and Gaziantep provinces of Turkey where virus-like symptoms were noted in samples collected during the 2007-2008 growing season. Leaf and bulb samples were taken from 202 plants with leaf yellow stripe, mosaic, enations, and deformation or dwarfism symptoms. ELISA was performed with antibodies from Agdia (Elkhart, IN). Results indicated that 57 samples (28.2%) were infected with OYDV and 43 samples (21.2%) were infected with LYSV. In addition, 23 samples were determined to be infected by both viruses. All ELISA-positive samples and 10 ELISA-negative samples were analyzed by reverse transcription-PCR with primers 1OYDV-G (5' TTA CAT TCT AAT ACC AAG CA 3') and 2OYDV-G (5' GCA GGA GAT GGG GAG GAC GC 3') for the detection of OYDV and primers 1LYSV (5' TCA CTG CAT ATG CGC ACC AT 3') and 2LYSV (5' GCA CCA TAC AGT GAA TTG AG 3') for the detection of LYSV. These primers were previously reported to be specific for the coat protein genes of OYDV and LYSV, respectively (2). Products of the expected size (774 bp for OYDV and 1,020 bp for LYSV) were amplified only from the ELISA-positive samples of the respective viruses, confirming infections by OYDV and LYSV. To our knowledge, this is the first report of OYDV and LYSV in garlic in Turkey. References: (1) L. Bos et al. Neth. J. Plant Pathol. 84:185, 1978. (2) T. V. M. Fajardo et al. Fitopatol.

Abstract
This work is a part of an ongoing effort to develop vaccinia virus recombinants expressing various Brucella abortus proteins. The B. abortus groEL gene encoding the antigenic heat shock protein GroEL was subcloned into vaccinia virus via homologous recombination and expression confirmed by Western blotting. Female BALB/c mice inoculated with recombinant vaccinia virus/GroEL produced GroEL and vaccinia virus specific antibodies. Mice were challenged 8 weeks post-inoculation with virulent B. abortus strain 2308 and protection measured by the rate of clearance of live Brucella from spleens. Although induction of specific immune response to GroEL and vaccinia virus was demonstrated by the appearance of antibodies in mice, no significant level of protection was demonstrable.
