Abstract
Tight relationships exist in the local Universe between the central stellar properties of galaxies and the mass of their supermassive black hole (SMBH)1-3. These suggest that galaxies and black holes co-evolve, with the main regulation mechanism being energetic feedback from accretion onto the black hole during its quasar phase4-6. A crucial question is how the relationship between black holes and galaxies evolves with time; a key epoch to examine this relationship is at the peaks of star formation and black hole growth 8-12 billion years ago (redshifts 1-3)7. Here we report a dynamical measurement of the mass of the black hole in a luminous quasar at a redshift of 2, with a look back in time of 11 billion years, by spatially resolving the broad-line region (BLR). We detect a 40-μas (0.31-pc) spatial offset between the red and blue photocentres of the Hα line that traces the velocity gradient of a rotating BLR. The flux and differential phase spectra are well reproduced by a thick, moderately inclined disk of gas clouds within the sphere of influence of a central black hole with a mass of 3.2 × 108 solar masses. Molecular gas data reveal a dynamical mass for the host galaxy of 6 × 1011 solar masses, which indicates an undermassive black hole accreting at a super-Eddington rate. This suggests a host galaxy that grew faster than the SMBH, indicating a delay between galaxy and black hole formation for some systems.

Abstract
About 30% of patients with epilepsy are drug resistant. Lennox-Gastaut syndrome (LGS), Dravet syndrome (DS) and tuberous sclerosis complex (TSC) are diseases for which high-purified-cannabidiol (CBD) known as Epidiolex® (GW pharma) can be prescribed in add-on of other medications in case of drug-resistance. Currently, there are only a few recent data in the literature about the efficacy and safety of CBD in other forms of refractory epilepsies especially focal epilepsies in adults. We report retrospectively the experience of high-purified-CBD use in two French reference medical centers for epilepsy in various forms of drug-resistant epilepsy. We distinguished two groups of patients: group A with epileptic encephalopathies and group B with focal or multifocal epilepsy. Safety and efficacy (% of responder patients) were evaluated. Finally, 73 patients (51 in group A and 22 in group B) used high-purified CBD as an add-on treatment for their drug-resistant epilepsy. Patients in group A were significantly younger (P=0.0155), with a longer exposition of treatment (P=0.0497) than group B and with higher doses (P=0.0300). Respectively, 15 patients (29.4%) and five patients (22.7%) were responders during the follow-up period (P=0.552). The association with clobazam was more frequent in responders than in non-responder patients (16 patients [80%] versus four [20%]). The most frequent side effect was somnolence. At the end of follow-up, 15 patients in group A (29.4%) and nine patients in group B (40.1%) had stopped the high-purified-CBD treatment due to aggravation of seizure, absence of positive effects, or adverse events. This study showed no significant difference regarding the type of drug-resistant epilepsy and suggests that this treatment may be of interest for all types of drug-resistant epilepsy.

Abstract
Background Art-based education is gaining interest in the medical field, particularly in specialties with a strong visual focus. Visual arts are increasingly used for the development of observational skills and social competencies. While content and objectives of art-based programs widely differ across medical faculties in the Netherlands, the diverse range of options underscore the interest in and the potential of this educational approach. In this report, we explore the value of art-based observational training for medical students and surgical residents in two prominent Dutch museums in Amsterdam and Rotterdam, respectively. Methods Our program, conducted at the Rijksmuseum in Amsterdam and Depot Boijmans van Beuningen Museum in Rotterdam engaged medical students (n=24) and surgeons (in training) (n=66) in an interactive workshop focused on art observation led by an experienced art-educator and a clinical professional. Learning objectives were defined and a post-workshop questionnaire was devised to evaluate participants' perceptions, with a specific focus on contribution of the program to professional development. Results Both residents and surgeons acknowledged that the program had a positive impact on their professional skills. The program learned them to postpone their judgements and contributed to the awareness of their personal bias. Notably, medical students believed in the program's potential contribution to their professional development. Surgeons were more critical in their evaluation, emphasizing the challenge of sustainable improvement of skills within the limited duration of the course. Conclusions An interactive art-based medical education program was offered to medical students, PhD students, house officers, surgical residents and surgeons in two well known Dutch museums. Participants expressed enthusiasm for the innovative educational approach they experienced at the museums. They learned about the importance of critical observation in their professional work, handling of ambiguity and got the opportunity to practice both observational and communicational skills in a creative manner. The findings indicate that medical students and surgical residents can benefit from art-based observational training, using art as a vehicle to develop their professional competencies.

Abstract
BACKGROUND MRI-guided biopsy (MGB) contributes to the diagnosis of clinically significant Prostate Cancer (csPCa). However, there are no clear recommendations for the management of men after a negative MGB. The aim of this study was to assess the risk of csPCa after a first negative MGB. METHODS Between 2014 and 2020, we selected men with a PI-RADS score ≥ 3 on MRI and a negative MGB (showing benign findings) performed for suspected prostate cancer. MGB (targeted and systematic biopsies) was performed using fully integrated mobile fusion imaging (KOELIS). The primary endpoint was the rate of csPCa (defined as an ISUP grade ≥ 2) diagnosed after a first negative MGB. RESULTS A total of 381 men with a negative MGB and a median age of 65 (IQR: 59-69, range: 46-85) years were included. During the median follow-up of 31 months, 124 men (32.5%) had a new MRI, and 76 (19.9%) were referred for a new MGB, which revealed csPCa in 16 (4.2%) of them. We found no statistical difference in the characteristics of men diagnosed with csPCa compared with men with no csPCa after the second MGB. CONCLUSION We observed a risk of significant prostate cancer in 4% of men two years after a negative MRI-guided biopsy. Performing a repeat MRI could improve the selection of men who will benefit from a repeat MRI-guided biopsy, but a clear protocol is needed to follow these patients. LEVEL OF EVIDENCE: 4

Abstract
OBJECTIVE Stereoelectroencephalography-guided radiofrequency thermocoagulation (SEEG-guided RF-TC) aims to reduce seizure frequency by modifying epileptogenic networks through local thermocoagulative lesions. Although RF-TC is hypothesized to functionally modify brain networks, reports of changes in functional connectivity (FC) following the procedure are missing. We evaluated, by means of SEEG recordings, whether variation in brain activity after RF-TC is related to clinical outcome. METHODS Interictal SEEG recordings from 33 DRE patients were analyzed. Therapeutic response was defined as more than 50% reduction in seizure frequency for at least one month following RF-TC. Local (power spectral density, PSD) and FC changes were evaluated in three-minute segments recorded shortly before (baseline), shortly after and 15 minutes after RF-TC. The PSD and FC strength values after thermocoagulation were compared with baseline as well as between the responder and non-responder groups. RESULTS In responders, we found a significant reduction in PSD after RF-TC in channels that were thermocoagulated (TC) for all frequency bands (p-value =0.007 for broad, delta and theta, p-value <0.001 for alpha and beta bands). However, we did not observe such PSD decrease in non-responders. At the network level, non-responders displayed a significant FC increase in all frequency bands except theta (broad, delta, beta band: p-value < 0.001; alpha band: p-value < 0.01), while responders showed a significant FC decrease in delta (p-value<0.001) and alpha bands (p-value<0.05). Non-responders showed stronger FC changes with respect to responders exclusively in TC channels (broad, alpha, theta, beta: p-value>0.05; delta: p= 0.001). SIGNIFICANCE Thermocoagulation induces both local and network-related (FC) changes in electrical brain activity of patients with DRE lasting for at least 15 minutes. This study demonstrates that the observed short-term modifications in brain network and local activity significantly differ between responders and non-responders and opens new perspectives for studying the longer-lasting functional connectivity changes after RF-TC.

Abstract
OBJECTIVE Temporal lobe epilepsy is the most common type of focal drug-resistant epilepsy. Seizures with predominant involvement of basal temporal regions (BTR) are not well characterized. In this stereo electroencephalography (SEEG) study, we aimed at describing the ictal networks involving BTR and the associated clinical features. METHODS We studied 24 patients explored with SEEG in our center with BTR sampling. We analyzed their seizures using a quantitative method: the "epileptogenicity index". Then we reported the features of the patients with maximal epileptogenicity within BTR, especially ictal network involved, ictal semiology and post-surgical outcome. RESULTS We found that rhinal cortex, parahippocampal cortex and posterior fusiform gyrus were the most epileptogenic structures within the BTR (mean EI: 0.57, 0.55, 0.54 respectively). Three main groups of epileptogenic zone organization were found: anterior (23% of total seizures) posterior (30%) and global (47%, both anterior and posterior). Contralateral spread was found in 35% of left seizures and 20% of right seizures. Naming deficit was more prevalent in left BTR (71% vs 29% in right seizures; p = 0.01) whereas automatic speech production was preferentially represented in right seizures (11% vs 54%; p = 0.001). Surgery was proposed for 11 patients (45.8%), leading to seizure freedom in 72% (Engel Class I). One patient presented post-operative permanent functional deficit. CONCLUSION Basal-temporal lobe epilepsy seems to be a specific entity among the temporal epilepsy spectrum with specific clinical characteristics. Resective surgery can be proposed with good outcomes in a significant proportion of patients and is safe provided that adequate language assessment has been preoperatively made.

Abstract
The hippocampus and amygdala are key brain structures of the medial temporal lobe, involved in cognitive and emotional processes as well as pathological states such as epilepsy. Despite their importance, it is still unclear whether their neural activity can be recorded non-invasively. Here, using simultaneous intracerebral and magnetoencephalography (MEG) recordings in patients with focal drug-resistant epilepsy, we demonstrate a direct contribution of amygdala and hippocampal activity to surface MEG recordings. In particular, a method of blind source separation, independent component analysis, enabled activity arising from large neocortical networks to be disentangled from that of deeper structures, whose amplitude at the surface was small but significant. This finding is highly relevant for our understanding of hippocampal and amygdala brain activity as it implies that their activity could potentially be measured non-invasively.

Abstract
Pediatric acute myeloid leukemia (AML) is a rare disease whose prognosis is highly variable according to factors such as chromosomal abnormalities. Recurrent genomic rearrangements are detected in half of pediatric AML by karyotype. NUcleoPorin 98 (NUP98) gene is rearranged with 31 different fusion partner genes. These rearrangements are frequently undetected by conventional cytogenetics, as the NUP98 gene is located at the end of the chromosome 11 short arm (11p15). By screening a series of 574 pediatric AML, we detected a NUP98 rearrangement in 22 cases (3.8%), a frequency similar to CBFB-MYH11 fusion gene (4.0%). The most frequent NUP98 fusion gene partner is NSD1. These cases are homogeneous regarding their biological and clinical characteristics, and associated with bad prognosis only improved by bone marrow transplantation. We detailed the biological characteristics of these AML by exome sequencing which demonstrated few recurrent mutations (FLT3 ITD, WT1, CEBPA, NBPF14, BCR and ODF1). The analysis of the clonal structure in these cases suggests that the mutation order in the NUP98-rearranged pediatric AML begins with the NUP98 rearrangement leading to epigenetic dysregulations then followed by mutations of critical hematopoietic transcription factors and finally, activation of the FLT3 signaling pathway.

Abstract
INTRODUCTION Anti-leucine rich glioma inactivated 1 encephalitis is a common and a treatable etiology of autoimmune encephalitis. Its diagnosis is a challenge because the initial diagnostic work-up is often normal. CASE REPORT A 48-year-old man experienced cognitive and behavioral troubles, facio-brachial dystonic seizures and a syndrome of inappropriate antidiuretic hormone secretion. First line tests excluded infectious, neoplastic, systemic inflammatory, endrocrine or toxic etiologies. Cerebral (18)Fluoro-desoxy-glucose (FDG) position emission tomography and research of specific antibodies in cerebro-spinal fluid and serum led to diagnose an anti-leucine rich glioma inactivated 1 encephalitis. Intravenous immunoglobulins and corticosteroids were partially effective. Cyclophosphamid permitted a good recovery. CONCLUSION In the presence of acute neuropsychiatric disorders with a negative etiologic research, physician should think about dysimmune encephalitis. Facio-brachial dystonic seizures and syndrome of inappropriate antidiuretic hormone secretion are highly evocative of anti-leucine rich glioma inactivated 1 encephalitis. The diagnosis needs specific diagnostic tests (cerebral (18)FDG position emission tomography and antibodies research in cerebro-spinal fluid and in serum), after the exclusion of alternative diagnoses. Extensive and repeated diagnostic work-up for neoplasia is required. Immunosupressive therapies are effective in most cases.

Abstract
BACKGROUND Partial nephrectomy (PN) has become the gold standard for the treatment of small tumors confined to the kidney. As result, the number of PN procedures increased during the last years. Subsequently, we have more often to deal with the complications of this surgery. Among these, pseudoaneurysms are rare but potentially life-threatening due to a risk of bleeding. Therefore, pseudoaneurysms have to be treated according to a relevant strategy. METHODS We performed a literature review of the cases of pseudoaneurysm after PN was reported as well as a focus on the different treatment strategies and their outcomes. RESULTS The incidence of pseudoaneurysm is low, ranging from 0.5% to 4%. Radio-embolization represents the gold standard treatment, used in 98% of the cases reported in the literature, allowing high success rate and rare morbidity. However, in some selected cases, surveillance could be an alternative.

Abstract
BACKGROUND To discuss the therapeutic approach for primary neurolymphomatosis. METHODS We report all primary neurolymphomatosis cases referred to our institution, with descriptions of clinical, radiological, electrophysiological, histological features and long-term follow-up. We treated all patients with a combination of high-dose methotrexate and alkylating agents. RESULTS Five patients were diagnosed with histologically confirmed primary neurolymphomatosis. The majority of them presented with painful asymmetric sensory-motor neuropathy. Magnetic resonance imaging was abnormal in 4 of 5 patients, as shown with gadolinium enhancements. Electroneuromyography revealed denervation in all 4 cases with contributive examinations. All our patients received a chemotherapy combination of high-dose methotrexate and alkylating agent. Median progression-free survival was 8 months (2 complete responses and 2 partial responses), and overall survival was 24 months. CONCLUSIONS Primary neurolymphomatosis is rare and polymorphic; it represents a difficult diagnosis of neuropathy. In our cohort, treatment with a chemotherapy combination with high-dose methotrexate showed encouraging results.

Abstract
INTRODUCTION Tracheobronchial rupture (TBR) due to blunt chest trauma is a rare but life-threatening injury in the pediatric age group. The aim of this study was to propose a treatment strategy including bronchoscopy, surgery and extracorporeal membrane oxygenation (ECMO) to optimize the emergency management of these patients. METHODS We reviewed a series of 27 patients with post-traumatic TBR treated since 1996 in our pediatric trauma center. RESULTS Seven cases had persistent and large volume air leaks. Flexible bronchoscopy was performed in cases of persistent or large volume air leaks. It permitted accurate visualization of the rupture and its extent. It allowed for a clear-cut positioning of the endotracheal tube. Five were managed operatively. Four cases were considered to be life-threatening because of the combination of severe respiratory distress with hemodynamic instability. One of them had severe tracheal laceration and died. Another one had bilateral bronchi disconnection. Based on clinical and endoscopic findings, surgical repair was performed using extracorporeal membrane oxygenation as a ventilatory support. It provided quick relief from the injury, which was previously expected to result in a fatal issue. CONCLUSIONS Prompt diagnosis and accurate management of surviving patients admitted to emergency rooms are necessary. Bronchoscopy remains a critical diagnosis step. Surgery is warranted for large tracheobronchial tears and ECMO could be beneficial as supportive therapy for selected cases.

Abstract
The number of Laparoscopic Roux-en-Y Gastric Bypass (LRYGB) procedures for morbid obesity and type 2 diabetes mellitus will increase worldwide, and therefore, an increase in perioperative morbidity can be anticipated. The authors present three cases based on different complications after LRYGB to demonstrate the diagnostic challenge that clinicians face in this particular group of patients. Also, a review of the literature covering the value of different imaging in these particular cases is provided by the authors. The role of imaging in the diagnostic process is discussed.

Abstract
Tendons may be affected by a variety of pathologic conditions, including those caused by overuse and inflammatory diseases. Sonography is a very sensitive means of detecting tendonous pathology because of its spatial resolution and its comparative and dynamic capabilities. Moreover its wide availability makes it the preferred first-line imaging modality in these cases. This paper reviews the inflammatory and degenerative conditions that may involve the tendons and their sonographic appearances.

Abstract
Benign recurrent intrahepatic cholestasis (BRIC) is a syndrome characterized by recurrent episodes of cholestasis with associated pruritus. The intensity and duration of cholestatic episodes, and the length of the intervening periods, vary unpredictably. We report the case of a patient with BRIC who was incapacitated by a severe intractable cough that accompanied marked pruritus during her second cholestatic episode. No cause for the cough was found, and it resolved spontaneously with amelioration of mild restrictive abnormalities of pulmonary function as the cholestasis subsided. Although cough has not been recognized as a complication of cholestasis, we postulate that it may occur either (i) as a result of direct stimulation of sensory nerves by circulating humoral substances related to the cholestasis that act either peripherally in the airways or centrally, or (ii) through stimulation of the vagus nerve in the liver, leading to cough that is mediated either centrally or by reflex.

Abstract
Although potentially noxious compounds are used routinely to disinfect endoscopes, reports of their inadvertent introduction to the gastrointestinal tract, usually attributed to the retention of disinfectant within endoscope channels, are rare. This case report describes the clinical features of glutaraldehyde-induced colitis and the pathology of the mucosal injury in four patients, in at least one of whom the disinfectant was not retained in the endoscope itself. Within 3 months, three patients experienced severe acute proctocolitis < 6 hours after a sigmoidoscopy showing no abnormalities, performed in a small endoscopy unit. Investigation of the unit's protocols suggested that the most likely cause was retention of 2% glutaraldehyde disinfectant in the endoscope channels, and changes were made to prevent this. When a fourth case occurred 5 months later, the source of the glutaraldehyde was found to be the tubing connecting water bottles to the endoscopes, which was disinfected rigorously but flushed inconsistently between cases. Glutaraldehyde-induced colitis seems similar to ischemic colitis in biopsy specimens and cannot be diagnosed by histological analysis alone. Acute colitis occurring within 24 hours of a colonoscopy showing no abnormalities should be considered iatrogenic and should lead to an investigation of procedures in use for cleaning and disinfecting endoscopic equipment.

Abstract
We describe the clinical features, liver histology, and ultrastructure in reversible diclofenac-induced hepatitis and review previous reports of this entity. Although rarely reported, diclofenac hepatitis may be severe, and even fatal. Symptoms, which develop from 1 week to 11 months after starting the drug, include jaundice, pruritus, fever, abdominal pain, nausea, vomiting, and rash. Bilirubin and alkaline phosphatase are mildly elevated, transaminases often markedly so. The nature of the idiosyncratic injury appears variable, some cases having features of a hypersensitivity reaction, most being more suggestive of a toxic metabolic effect. Light microscopy shows a nonspecific hepatitis with portal and lobular activity, and focal hepatocellular injury that may progress to zonal or massive necrosis. The ultrastructural features in our case are typical of drug or toxin injury. This may be of value in distinguishing this entity from other forms of hepatitis, which is important in view of the frequent reversibility of this potentially lethal form of injury.
