Abstract
Background: It is widely acknowledged that carbon dioxide (CO 2), a greenhouse gas, is largely responsible for climatic changes that can lead to warming or cooling in various places. This disturbs natural processes, creating instability and fragility of natural and social ecosystems. To combat climate change, without compromising technology advancements and maintaining production costs at acceptable levels, carbon capture and storage (CCS) technologies can be deployed to advance a non-disruptive energy transition. Capturing CO 2 from industrial processes such as thermoelectric power stations, refineries, and cement factories and storing it in geological mediums is becoming a mature technology. Part of the Mesohellenic Basin, situated in Greek territory, is proposed as a potential area for CO 2 storage in saline aquifers. This follows work previously done in the StrategyCCUS project, funded by the EU. The work is progressing under the Pilot Strategy, funded by the EU. Methods: The current investigation includes geomechanical and petrophysical methods to characterise sedimentary formations for their potential to hold CO 2 underground. Results: Samples were found to have both low porosity and permeability while the corresponding uniaxial strength for the Tsotyli formation was 22 MPa, for Eptechori 35 MPa and Pentalofo 74 MPa. Conclusions: The samples investigated indicate the potential to act as cap-rocks due to low porosity and permeability, but fluid pressure within the rock should remain within specified limits; otherwise, the rock may easily fracture and result in CO 2 leakage or/and deform to allow the flow of CO 2. Further investigation is needed to identify reservoir rocks as well more sampling to allow for statistically significant results.

Abstract
BACKGROUND Cancer treatment-related nausea and vomiting continue to be common and distressing symptoms for patients, despite improvements in antiemetics. Dietary modifications could potentially improve this symptom experience. Clinicians frequently provide dietary advice to patients, although the evidence base of such suggestions or recommendations is not clear. PURPOSE This systematic review aimed to examine the current literature on food interventions associated with improvements in cancer treatment-related nausea and vomiting. METHODS Eight electronic databases were searched with a specific search term strategy covering trials without time or language limitations. Eligible studies focused on a food substance, defined as any nutritious substance that people eat or drink to maintain life and well-being. Trials in children and adults during chemotherapy or radiotherapy were included. Cochrane risk of bias tool was used to assess trial quality and GRADE was used to assess the certainty in the effect of each outcome. RESULTS Seventeen trials were included, 3 focusing on children and 14 on adults. Two trials included patients receiving radiation. Ten out of 17 trials (59%) had a high risk of bias. Strongest evidence with highest certainty was found for dietary counseling to meet macronutrient requirements in reducing incidence of radiotherapy-related nausea and vomiting in adults (n=2 studies; n=124 participants; GRADE level: moderate). There was also moderate certainty in the beneficial effect of protein supplementation on nausea and vomiting incidence in adults during radiotherapy (n=2 studies; n=124 participants; GRADE level: moderate). A significant positive effect on CINV incidence and/or severity in adults was also found for dietary counseling to meet macronutrient requirements during chemotherapy, a peppermint drink, scaly wood mushroom, chamomile, protein with ginger, and a colorless odorless diet (GRADE level: low to very low). CONCLUSIONS The review identified food-based approaches that could improve the nausea and vomiting experience in patients with cancer and provide guidance to clinicians. However, confidence in these findings was low and studies were heterogeneous and mostly of low quality, requiring further investigation before stronger recommendations can be made. Future research is needed to confirm efficacy and safety. TRIAL REGISTRATION PROSPERO CRD42022341154.

Abstract
Recently, many plant-derived bioactive agents have been included in dermo-cosmetics formulations. This leads to an extensive portfolio of innovative products with an expanded range of benefits, including anti-aging, antioxidant, hydrating and depigmenting. Although different technologies drawing on science and nature are used to create these high-performing molecules, there remains some debate about the mechanism of action of the natural bioactive ingredients within dermo-cosmetics. This review recapitulates the main biological mechanisms underlying the activity of natural active ingredients, with a specific focus on their synergistic use for the management of common, yet quite specific, skin conditions. A total of 28 plant-derived bioactives were selected from the Givaudan Active Beauty (Argenteuil, France) portfolio, a multinational company specializing in innovative natural actives research. An extensive literature review about their biological activity was conducted by a PubMed search using different keywords. No language or publication date restrictions were used. Givaudan Active Beauty data on file were also considered. The bioactive ingredients were described according to the pathogenetic mechanisms underlying 10 common skin conditions that dermo-cosmetics may address. Literature data have shown that plant-derived bioactives are involved in a wide range of biological mechanisms showing anti-inflammatory, antioxidant, and moisturizing properties, along with skin barrier protection and collagen synthesis activities. As a result, different combinations of bioactives within dermo-cosmetics can be defined to counteract simultaneously the different pathogenetic mechanisms underlying different skin conditions. Available literature supports the synergistic use of plant-derived bioactive agents within dermo-cosmetics as a viable and safe option for managing the most common skin conditions.

Abstract
BackgroundGallbladder cancer (GBC) represents the most common biliary tract cancer. Prognosis remains poor with 5-year overall survival rates less than 5% in advanced stages. GBCs are diagnosed more frequently in women, supposedly due to endocrine factors.CaseA 35-year-old woman, diagnosed with a non-metastatic GBC in the 22nd week of gestation, underwent a complete surgical resection 5 weeks later. Adjuvant gemcitabine was administered without complications, temporarily discontinued in the 32nd week to allow childbirth. The patient was disease-free for more than 3 years with ongoing remission at the last visit in July 2022. During the follow-up period, the child had no developmental, cognitive, or other health issues.ConclusionMalignant tumors occur in about 0.1% of pregnant women, many are treated with chemotherapy. In oncology, the need to deliver optimal treatment in these patients represents a major concern. Both surgery and adjuvant chemotherapy of locally advanced GBC can be performed safely, with certain considerations, in the second trimester of pregnancy.

Abstract
Objective To analyze the humoral response after COVID-19 vaccination in patients with multiple sclerosis (MS) according to disease-modifying treatments (DMTs) and in comparison with the humoral response after SARS-CoV-2 infection. Methods We included 28 MS patients with serological results after COVID-19 vaccination (Pfizer-BioNTech or Moderna ARNm) and 61 MS patients with serological results after COVID-19 (COVID-19 group) among patients followed up at the MS Center of Strasbourg, France, between January and April 2021. The primary endpoint was the IgG index according to DMTs (anti-CD20 mAb, sphingosine 1-phosphate receptor [S1PR] modulator and other treatments) and COVID-19 vaccine or COVID-19 groups. Results In the vaccinated MS patients, the median IgG index was lower in patients treated with anti-CD20 mAb and in patients treated with S1PR modulator compared to patients receiving other or no DMTs (4.80 [1.58–28.6], 16.5 [16.3–48.5], 1116 [434–1747] and 1272 [658–1886], respectively, P < 0.001). Similar results were found for MS patients after COVID-19. Conclusions Patients with MS and treated with S1PR modulators or anti-CD20 mAb had a reduced humoral response after COVID-19 vaccine.

Abstract
INTRODUCTION The spinal cord is one of the two main targets of neuromyelitis optica (NMO). The aim of this study was to highlight cervical spinal cord atrophy in NMO patients as compared to controls and to assess correlations between atrophy and clinical characteristics and cervical spinal cord MRI data. METHODS This prospective study investigated 15 patients with a diagnosis of NMOSD and 15 healthy controls. The whole cervical spinal cord was explored by MRI. The cross-sectional area (CSA) was estimate at every level of cup. This measurement was then averaged on the whole cervical spinal cord, providing a single measurement for every subject, denoted as mean CSA. RESULTS Mean CSA was 68.5 mm2 in the population of NMO patients and 72.8 mm2 in the population of healthy subjects. NMO patients had significantly smaller cervical spinal cord area than healthy controls (T test=0.009). Cervical spinal cord atrophy was associated with clinical signs of medullary involvement (T test=0.0006). There was a tendency toward a relation between cervical spinal cord atrophy and the Expanded Disability Status Scale (EDSS) (T test=0.07). This correlation seems statistically significant (T test<0.05) at the level of the upper cervical spinal cord (C2-C3) CONCLUSION: This study provides the first evidence of cervical spinal cord atrophy in NMOSD by studying the entire cervical spinal cord. Upper cervical spinal cord atrophy was substantially correlated to clinical disability and seems more involved in the development of clinical disability in NMOSD patients in comparison to the lower cervical spinal cord.

Abstract
The mechanism behind the 1H nuclear magnetic resonance (NMR) frequency dependence of T1 and the viscosity dependence of T2 for polydisperse polymers and bitumen remains elusive. We elucidate the matter through NMR relaxation measurements of polydisperse polymers over an extended range of frequencies (f0 = 0.01-400 MHz) and viscosities (η = 385-102 000 cP) using T1 and T2 in static fields, T1 field-cycling relaxometry, and T1ρ in the rotating frame. We account for the anomalous behavior of the log-mean relaxation times T1LM ∝ f0 and T2LM ∝ (η/T)-1/2 with a phenomenological model of 1H-1H dipole-dipole relaxation, which includes a distribution in molecular correlation times and internal motions of the nonrigid polymer branches. We show that the model also accounts for the anomalous T1LM and T2LM in previously reported bitumen measurements. We find that molecular dynamics (MD) simulations of the T1 ∝ f0 dispersion and T2 of similar polymers simulated over a range of viscosities (η = 1-1000 cP) are in good agreement with measurements and the model. The T1 ∝ f0 dispersion at high viscosities agrees with previously reported MD simulations of heptane confined in a polymer matrix, which suggests a common NMR relaxation mechanism between viscous polydisperse fluids and fluids under nanoconfinement, without the need to invoke paramagnetism.

Abstract
We consider the motion of a droplet bouncing on a vibrating bath of the same fluid in the presence of a central potential. We formulate a rotation symmetry-reduced description of this system, which allows for the straightforward application of dynamical systems theory tools. As an illustration of the utility of the symmetry reduction, we apply it to a model of the pilot-wave system with a central harmonic force. We begin our analysis by identifying local bifurcations and the onset of chaos. We then describe the emergence of chaotic regions and their merging bifurcations, which lead to the formation of a global attractor. In this final regime, the droplet's angular momentum spontaneously changes its sign as observed in the experiments of Perrard et al. [Phys. Rev. Lett.113(10), 104101 (2014)].

Abstract
The interfacial area between two immiscible phases in porous media is an important parameter for describing and predicting 2 phase flow. Although present in several models, experimental investigations are sparse due to the lack of appropriate measurement techniques. We propose two NMR techniques for the measurement of oil-water interfacial area: (i) a time dependent NMR diffusion technique applicable in static conditions, similar to those used for the measurement of the solid specific surface of a porous media, and (ii) a fast relaxation technique applicable in dynamic conditions while flowing, based on an interfacial relaxation mechanism induced by the inclusion of paramagnetic salts in the water phase. For dodecane relaxing on doped water, we found an oil interfacial relaxivity of 1.8μm/s, large enough to permit the measurement of specific interfacial surface as small as 1000cm2/cm3. We demonstrate both NMR techniques in drainage followed by imbibition, in a model porous media with a narrow pore size distribution. While flowing, we observe that the interfacial area is larger in imbibition than in drainage, implying a different organization of the oil phase. In a carbonate sample with a wide pore size distribution, we evidence the gradual invasion of the smallest pores as the oil-water pressure difference is increased.

Abstract
INTRODUCTION The intercostal nerves (ICN) transfer to the musculocutaneous nerve (MCN) can restore elbow flexion in complete brachial plexus palsy. The last cases our service dealt with, allowed our staff to observe two different situations. In the 2 first patients, we were able to proceed with an intraneurodissection of the MCN motor component up to the axillary cavity level, while on the third case such dissection could not be performed as high. The aim of this work is to assess the feasibility of a transfer on the MCN's motor component. MATERIAL AND METHODOLOGY We conducted a series of 5 cadaver dissections of the MCN and ICN on the anatomy laboratory. Using magnifying loupes to perform an intraneurodissection, we were able to split the motor and sensory fibers as they stood out. It would help motor recuperation avoiding directional error on sensitive component. RESULTS The ICN can be sutured on the motor component of the MCN, provided the dissection is very minutious. DISCUSSION The intraneurodissection of the MCN up to the axillary cavity level is possible as the interfascicular exchanges are scarce there. Publications already refer to the possibility of a nerve transfer between the ICN and the motor component of the MCN. Therefore, our researches suggest that such a procedure can be considered for routine procedures. CONCLUSION The neurotization is one of the latest breakthroughs in terms of brachial plexus surgery. We are hopeful that anatomical researches could lead to optimization possibilities.

Abstract
BACKGROUND Merkel cell polyomavirus (MCPyV) is the main aetiological agent of Merkel cell carcinoma (MCC). Serum antibodies against the major MCPyV capsid protein (VP1) are detected in the general population, whereas antibodies against MCPyV oncoproteins (T antigens) have been reported specifically in patients with MCC. OBJECTIVES The primary aim was to assess whether detection of serum antibodies against MCPyV proteins at baseline was associated with disease outcome in patients with MCC. The secondary aim was to establish whether evolution of these antibodies during follow-up was associated with the course of the disease. METHODS Serum T-antigen and VP1 antibodies were assessed by enzyme-linked immunosorbent assay using recombinant proteins in a cohort of 143 patients with MCC, including 84 patients with serum samples available at baseline. RESULTS Low titres of VP1 antibodies at baseline (< 10 000) were significantly and independently associated with increased risk of recurrence [hazard ratio (HR) 2·71, 95% confidence interval (CI) 1·13-6·53, P = 0·026] and death (HR 3·74, 95% CI 1·53-9·18, P = 0·004), whereas T-antigen antibodies were not found to be associated with outcome. VP1 antibodies did not differ between patients in remission and those with recurrence or progression during follow-up. However, T-antigen antibodies were more frequently detected in patients with recurrence or progression at 12 months (P = 0·020) and 24 months (P = 0·016) after diagnosis. CONCLUSIONS VP1 antibodies constitute a prognostic marker at baseline, whereas T-antigen antibodies constitute a marker of disease recurrence or progression if detected > 12 months after diagnosis.

Abstract
OBJECTIVE Description of the transfusion practice and its specificities in a geriatric unit. PATIENTS AND METHODS Prospective descriptive study realized by a single consultant. INCLUSION CRITERIA patients admitted in the unit between 01/10/2011 and 31/01/2012 with hemoglobin level below 10 g/dL. RESULTS Eighty-one patients: 87.7-year-old±5.6, ADL 2.1±1.9. CIRS 15.5±3.9. Forty-five (55.5%) of the patients received blood transfusion. Cause of admittance: anemia for 9% of patients. The etiology of anemia was multifactorial in the majority of cases. Admission hemoglobin rate: 9.1 g/dL±1.1 in transfused group versus 9.6 g/dL±0.5 for non-transfused patients. The clinical signs of anemia were asthenia (98.8%), impact on everyday activities (91.4%), respiratory distress (60.5%), stability disturbances and falls (38.3%), confusion (32.1%), hemodynamic disorders (29.6%). The increase of hemoglobin rate was 1.45 g/dL in the transfused group versus 0.3 g/dL for the non-transfused patients. A side effect was observed in 2 transfused patients (4.4%). DISCUSSION Transfusion decision criteria are rarely studied in geriatrics. The clinical signs of anemia include the classical hemodynamic disorders, cardio-respiratory and more specific of the elderly patients as confusion, majoring of cognitive decline and falls. The transfusion threshold (1.4 g/dL per 1 RBC unit) seems higher than in the overall transfused patients. Transfusion remains the fastest way to correct anemia but exposes to circulatory overload.

Abstract
We propose a versatile model specifically designed for the quantitative interpretation of NMR velocimetry data. We use the concept of mobile or immobile tracer particles applied in dispersion theory in its Lagrangian form, adding two mechanisms: (i) independent random arrests of finite average representing intermittent periods of very low velocity zones in the mean flow direction and (ii) the possibility of unexpectedly long (but rare) displacements simulating the occurrence of very high velocities in the porous medium. Based on mathematical properties related to subordinated Lévy processes, we give analytical expressions of the signals recorded in pulsed-field-gradient NMR experiments. We illustrate how to use the model for quantifying dispersion from NMR data recorded for water flowing through a homogeneous grain pack column in single- and two-phase flow conditions.

Abstract
The NMR propagator technique allows the measurements of the variance σ(2)=<(ξ-<ξ>)(2)> of the displacements as a function of time t when flowing in a porous media. The time dependence of σ is a very sensitive test of Gaussian behavior compared to the analysis of the shape of the propagators. Superdispersion occurs when σ(2)[proportionality]t(α) with the exponent α larger than 1. In a homogeneous 30-μm grain pack and 10 < Pe < 35, we observed weak superdispersion in saturated conditions (α = 1.17) and gradually strong superdispersion as the water saturation decreases (up to α = 1.5) during steady-state oil-water two-phase flow. In saturated conditions, the corresponding longitudinal propagators and breakthrough curves are Gaussian or nearly Gaussian, whereas in two-phase conditions, the longitudinal propagators are nonsymmetric and the breakthrough curves show a tail at long times.

Abstract
BACKGROUND Neuromyelitis optica (NMO) is an inflammatory disease associated with optic neuritis and myelitis. Recently, several studies showed that optical coherence tomography (OCT) could be an interesting method for the evaluation of disease severity; however, to date there are no studies with a longitudinal follow-up of visual function in NMO. The aim of this study was to assess the ability of OCT to evaluate the progression of visual dysfunction in NMO. PATIENTS AND METHODS A group of 30 NMO patients (thus, 60 eyes), comprised of 20 women and 10 men with a mean age of 43.7 +/- 12.3 years, were prospectively evaluated clinically and by a whole neuro-ophthalmological work-up, including: visual acuity (VA), fundoscopy, visual evoked potential (VEP), visual field (VF) and optical coherence tomography (OCT). All patients were tested at baseline (after a mean disease duration of 6.1 years) and after a mean time of follow-up of 18 months (range: 12-36 months). RESULTS Mean VA was similar at the two evaluation times (0.77 +/- 0.36 versus 0.77 +/- 0.35). The mean VF defect decreased slightly, but the difference was not significant (-5.9 +/- 1.3 dB versus -5.3 +/- 1.3 dB). In contrast, the mean retinal thickness seen on OCT decreased from 87.4 +/- 23.3 µm to 79.7 +/- 22.4 µm (p = 0.006). These modifications were only observed in eyes with a past or a recent history of optic neuritis (-15.1 µm; p < 0.001) and not in eyes without any history of optic neuritis (-2.4 µm; not significant). Also, they occurred independently of the occurrence of relapses (n = 13) and especially optic neuritis episodes; however, the number of optic neuritis episodes was low (n = 5). CONCLUSION OCT seems to be a more sensitive test than VA or VF for monitoring ophthalmological function in NMO and it seems to be helpful for the detection of infra-clinical episodes in patients with a past history of optic neuritis. Our results suggest that this easily performed technique should be used in the follow-up of NMO, but complementary studies are warranted to confirm its interest at an individual level.

Abstract
INTRODUCTION Meningiomas are benign primary meningeal tumors. Their diagnosis may be incidental or in response to a work-up for neurological or ophthalmological symptoms. PATIENTS AND METHODS The clinical course of five patients with ophthalmological symptoms leading to the diagnosis of meningioma is described. RESULTS The case reports consist of five women (48 to 54 years old - mean 52 years at the onset of symptoms), all suffering from a progressive unilateral decrease in visual acuity with a normal initial fundus examination and ipsilateral visual field changes. Ancillary testing, in particular MRI and CT-scans, had to be repeated to make the diagnosis of meningioma, which was delayed from 18 months to 4 years. DISCUSSION The clinical presentation of these five cases was that of a retrobulbar optic neuropathy, which biased the work-up towards an inflammatory disease of the central nervous system such as multiple sclerosis. However, the atypical character of the neuropathy, which did not respond to intravenous steroids, caused the diagnosis to be questioned and radiological examinations repeated. The iso-intense appearance of meningiomas on T1 MR imaging and only slightly hyperintense appearance on T2 may result in a diagnostic delay if the exam is not performed and interpreted by an experienced professional. Gadolinium contrast, fat suppression and centration on the anterior visual pathways are essential to a proper MRI examination. CONCLUSION When confronted with a progressive, painless optic neuropathy unresponsive to steroid treatment, the diagnosis of meningioma of the anterior visual pathways must be considered. This diagnosis is enabled by a targeted MRI of the anterior visual pathways.

Abstract
BACKGROUND Neuromyelitis optica (NMO) is an inflammatory disease involving predominantly the spinal cord and optic nerves. Whether patients with NMO have a loss in white or grey matter (GM) volumes remains to be determined. METHODS Thirty patients with NMO, 30 healthy subjects matched for age and gender, 21 patients with multiple sclerosis (MS) and 20 patients with a clinically isolated syndrome (CIS) were studied. We applied a SIENAX post-treatment software. We compared white matter (WM) and GM volumes between groups and explored correlations of changes in NMO patients with age, gender, duration, disease severity, visual acuity and T2 hyperintensities. We also performed a voxel-based morphometry (VBM) analysis to identify the regions affected by loss of volume. RESULTS White matter volume was significantly reduced in patients with NMO (764.4 ± 58.3 cm(3) ) compared to healthy subjects (843.1 ± 49.3 cm(3) ) (P < 0.001), whereas no difference was observed for the GM. Patients with CIS also presented an elective atrophy of WM and MS an atrophy of both WM and GM. We did not find any predictive factors of brain atrophy. The decrease in WM volume in NMO was noted even in the absence of visible MRI hypersignals. The VBM analysis found a few regions of WM atrophy (corpus callosum and optic radiations, P < 0.005, uncorrected) and a few regions of GM atrophy (thalamus and prefrontal cortex, P < 0.001, uncorrected). CONCLUSION These results suggest a significant brain involvement in NMO, especially an involvement of WM which appears not to be limited to secondary degeneration after spinal cord and optic nerve damage.

Abstract
BACKGROUND AND OBJECTIVES The chemical contamination during the preparation of cytotoxics remains a serious problem in hospital pharmacies and the operators could contribute to this risk during their manipulations. A validation protocol was developed using a non-toxic, highly detectable tracer, quinine dihydrochloride. METHOD Further, a method for a high recovery extraction and quantification of this marker, and a protocol covering the critical operations of cytotoxic preparation, was developed and validated. Various devices were used to fill the syringes and perfusion bags. All the filled containers and used materials were collected at the end of the protocol and the tracer was extracted in water. The contaminated water was analyzed by fluorimetry. The number of spots on the working pads was counted under ultraviolet light. During a total of 28 sessions, the procedure was applied by 20 different operators. RESULTS The mean cumulated quantities of contamination were 6.2 µL (0.6-23.8) and >10 spots (0-20), which was considered as high. No correlation was observed between the contamination rate and the operator's experience. CONCLUSION This validation protocol facilitates controlling the operators' working 'cleanliness' and helps to improve the initial and continuing training. This simple test presents an effective answer for the important issue of the chemical safety of operators.

Abstract
Standard reservoir evaluations are based on Archie's law relating the average water saturation to the average electrical resistivity by R(ind) = S(w)(-2). However, especially in the case of complex heterogeneous carbonates, deviation from Archie's law is observed and generally attributed to factors affecting the percolation or disconnectedness of the different phases (wetting films, microporosity, macropores) assuring electrical conductance. Pore-network models (PNM's) in combination with high-resolution computed microtomography (μ-CT) constitute a very effective tool to investigate the influence of the geometry and topology of the porous media on the spatial distribution of the conductive phase, and therefore on the shape of the resistivity index curve. An extended version of the classical PNM applicable to dual-porosity systems is presented. It combines the classical pore-network modeling applied on the macroporous space with the macroscopic properties of the microporous phase, supposing that the two pore systems act in parallel. Three-dimensional images provide information on the connectedness of the microporous phase, which is then included in the simulations. Electrical behavior of sandstone and two carbonates presenting distinct resistivity index curves were simulated and compared to measurements. Both Archie and "non-Archie" behavior were correctly reproduced, and the curve shape was explained considering percolation of the different phases.

Abstract
Background: Neuromyelitis optica (NMO) frequently begins with a monofocal episode of optic neuritis or myelitis. A concept named high-risk syndrome (HRS) for NMO has been proposed for patients with monofocal episodes and NMO-IgG antibodies. Objective: To describe HRS patients and compare them with NMO patients. Methods: We identified 30 patients with HRS: 18 with extensive myelitis (HRM) and 12 with optic neuritis (HRON), in a database pooling patients from 25 centres in France. Clinical, laboratory/magnetic resonance imaging (MRI) data and outcome were analysed and compared with a national cohort of 125 NMO patients extracted from the same database. Results: Mean follow-up was 4.8 years. Mean age at onset was 42.8 years (range: 12.4–70) with a female:male ratio of 0.9. Asymptomatic lesions were report on visual evoked potentials in 4/8 tested HRM patients and on spinal cord MRI in 2/7 HRON patients. Three patients died, two owing to a cervical lesion. HRS and NMO patients had similar clinical/paraclinical data, except for a predominance of men in the HRS group and a later mean age at onset in the HRM subgroup. Conclusion: The description of HRS patients is compatible with a monofocal form of NMO. Asymptomatic lesions could be included in a new set of NMO diagnostic criteria.

Abstract
BACKGROUND The burden of multiple sclerosis (MS) includes fatigue, depression and worsening of health-related quality of life (HRQOL). These changes have not been yet measured in neuromyelitis optica (NMO). Our aim was to assess the HRQOL, fatigue and depression in NMO. METHODS We administered French validated self-questionnaires on HRQOL (SEP-59), fatigue (EMIF-SEP) and depression (EHD) to 40 patients followed up in two centres. We assessed the relationship of these parameters with gender, age, disability, disease duration, visual acuity and NMO-antibody status and also compared our results with equivalent data in MS and normal subjects derived from previous studies. RESULTS Health-related quality of life scores were lower (P < 0.01) in patients with NMO when compared to normal subjects. No significant difference was noted between patients with NMO and MS for most scores, the exceptions being HRQOL related to cognitive function (better in NMO than in MS), HRQOL related to sphincter dysfunction (worse in NMO than in MS) and the psychological dimension of fatigue (milder in NMO than in MS). Disability was the main predictive factor of an unfavourable evolution. DISCUSSION This study reveals the strong impact of NMO on HRQOL, fatigue and depression and the importance of screening patients, especially the more disabled, so as to initiate suitable treatment.

Abstract
BACKGROUND Neuromyelitis optica (NMO) is a rare inflammatory disease. Average age at onset is 35 years. Few data exist on patients with pediatric-onset NMO (p-NMO), with disease onset before age 18 years. We report the clinical and paraclinical features and long-term outcome of patients with p-NMO and compare them with a large adult-onset NMO (a-NMO) cohort. METHODS We performed a retrospective, multicenter study of patients with p-NMO in pediatric and adult medical centers. We identified 125 patients with NMO (12 p-NMO; 113 a-NMO) fulfilling the 2006 criteria. Data were collected using hospital files and standardized assessment forms for NMO. RESULTS Patients with p-NMO were followed up during a mean 19.3 years. Median age at onset was 14.5 years (4.1-17.9) with a female:male ratio of 3:1. Three patients (25%) fulfilled Paty criteria for multiple sclerosis on first brain MRI, including one patient with acute disseminated encephalomyelitis. Median interval between onset and residual Expanded Disability Status Scale (EDSS) score 4 was 20.7 years, score 6 was 26 years, and score 7 was 28.7 years. Median interval between onset and residual visual loss ≤1/10 was 1.3 years. Compared with a-NMO, p-NMO showed a longer time to EDSS scores 4 and 6, largely explained by the severity of the first myelitis in the a-NMO group. Time to first treatment was longer in the p-NMO group (13.1 vs 3.4 years). CONCLUSION Patients with p-NMO can present a diffuse inflammatory process on first brain MRI and have a longer time to disability than patients with a-NMO.

Abstract
BACKGROUND There have been few epidemiologic studies on neuromyelitis optica (NMO) and none used the recent 2006 diagnostic criteria. Here we describe the clinical, laboratory, MRI, and disability course of NMO in a French cohort of 125 patients. METHODS We performed an observational, retrospective, multicenter study. Data were collected from September 2007 through August 2008, corresponding to the endpoint of the study. We identified 125 patients fulfilling the 2006 NMO criteria. Selection was made using hospital files and a specific clinical questionnaire for NMO. RESULTS Mean age at onset was 34.5 years (range 4-66) with a mean disease duration of 10 +/- 7.8 years at the endpoint. The patients were mainly (87%) Caucasian, with a female:male ratio of 3:1. In 90% of cases, the association of optic neuritis, longitudinal extensive myelitis, and a Paty-negative initial brain MRI was sufficient to fulfill the supportive criteria. Eighty-eight percent of patients were treated with immunosuppressive therapies. Median delay from onset to Expanded Disability Status Scale (EDSS) score 4 was 7 years; score 6, 10 years; and score 7, 21 years. The first episode of myelitis was immediately followed by an EDSS score > or = 4 in 37.3% of cases, and a severe residual visual loss was observed in 22% of patients after the first episode of optic neuritis. Multivariate analysis did not reveal any predictors of a poor evolution other than a high number of MRI brain lesions at diagnosis, which were predictive of a residual visual acuity < or = 1/10. CONCLUSIONS Our demographic data provide new data on disability in patients with neuromyelitis optica, most of whom were receiving treatment.

Abstract
Ataxia with oculomotor apraxia type 2 (AOA2) is an autosomal recessive disease due to mutations in the senataxin gene, causing progressive cerebellar ataxia with peripheral neuropathy, cerebellar atrophy, occasional oculomotor apraxia and elevated alpha-feto-protein (AFP) serum level. We compiled a series of 67 previously reported and 58 novel ataxic patients who underwent senataxin gene sequencing because of suspected AOA2. An AOA2 diagnosis was established for 90 patients, originating from 15 countries worldwide, and 25 new senataxin gene mutations were found. In patients with AOA2, median AFP serum level was 31.0 microg/l at diagnosis, which was higher than the median AFP level of AOA2 negative patients: 13.8 microg/l, P = 0.0004; itself higher than the normal level (3.4 microg/l, range from 0.5 to 17.2 microg/l) because elevated AFP was one of the possible selection criteria. Polyneuropathy was found in 97.5% of AOA2 patients, cerebellar atrophy in 96%, occasional oculomotor apraxia in 51%, pyramidal signs in 20.5%, head tremor in 14%, dystonia in 13.5%, strabismus in 12.3% and chorea in 9.5%. No patient was lacking both peripheral neuropathy and cerebellar atrophy. The age at onset and presence of occasional oculomotor apraxia were negatively correlated to the progression rate of the disease (P = 0.03 and P = 0.009, respectively), whereas strabismus was positively correlated to the progression rate (P = 0.03). An increased AFP level as well as cerebellar atrophy seem to be stable in the course of the disease and to occur mostly at or before the onset of the disease. One of the two patients with a normal AFP level at diagnosis had high AFP levels 4 years later, while the other had borderline levels. The probability of missing AOA2 diagnosis, in case of sequencing senataxin gene only in non-Friedreich ataxia non-ataxia-telangiectasia ataxic patients with AFP level > or =7 microg/l, is 0.23% and the probability for a non-Friedreich ataxia non-ataxia-telangiectasia ataxic patient to be affected with AOA2 with AFP levels > or =7 microg/l is 46%. Therefore, selection of patients with an AFP level above 7 microg/l for senataxin gene sequencing is a good strategy for AOA2 diagnosis. Pyramidal signs and dystonia were more frequent and disease was less severe with missense mutations in the helicase domain of senataxin gene than with missense mutations out of helicase domain and deletion and nonsense mutations (P = 0.001, P = 0.008 and P = 0.01, respectively). The lack of pyramidal signs in most patients may be explained by masking due to severe motor neuropathy.

Abstract
While Friedreich's ataxia (FRDA) and ataxia telangiectasia (AT) are known to be the two most frequent forms of autosomal recessive cerebellar ataxia (ARCA), knowledge on the other forms of ARCA has been obtained only recently, and they appear to be rarer. Little is known about the epidemiological features and the relative frequency of the ARCAs and only few data are available about the comparative features of ARCAs. We prospectively studied 102 suspected ARCA cases from Eastern France (including 95 from the Alsace region) between 2002 and 2008. The diagnostic procedure was based on a sequential strategic scheme. We examined the clinical, paraclinical and molecular features of the large cohort of patients and compared features and epidemiology according to molecular diagnosis. A molecular diagnosis could be established for 57 patients; 36 were affected with FRDA, seven with ataxia plus oculomotor apraxia type 2 (AOA2), four with AT, three with ataxia plus oculomotor apraxia type 1 (AOA1), three with Marinesco-Sjögren syndrome, two with autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS), one with ataxia with vitamin E deficiency (AVED) and one with autosomal recessive cerebellar ataxia type 2 (ARCA2). The group of patients with no identified mutation had a significantly lower spinocerebellar degeneration functional score corrected for disease duration (SDFS/DD ratio; p = 0.002) and comprised a significantly higher proportion of cases with onset after 20 years (p < 0.01). Extensor plantar reflexes were rarer and cerebellar atrophy was more frequent in the group of patients with a known non-Friedreich ARCA compared to all other patients (p < 0.0001 and p = 0.0003, respectively). Lower limb areflexia and electroneuromyographic evidences of peripheral neuropathy were more frequent in the Friedreich ataxia group than in the group with a known non-Friedreich ataxia and were more frequent in the later group than in the group with no identified mutation (p = 0.0001 and p = 0.01, respectively). The overall prevalence of ARCA in Alsace is 1/19,000. We can infer the prevalence of FRDA in Alsace to be 1/50,000 and infer that AT is approximately eight times less frequent than FRDA. MSS, AOA2 and ARSACS appear only slightly less frequent than AT. Despite the broad variability of severity, Friedreich ataxia patients are clinically distinct from the other forms of ARCA. Patients with no identified mutation have more often a pure cerebellar degenerative disease or a spastic ataxia phenotype. It appears that ARCA cases can be divided into two major groups of different prognosis, an early-onset group with a highly probable genetic cause and an adult-onset group with better prognosis for which a genetic cause is more difficult to prove but not excluded. ARCAs are rare, early-disabling and genetically heterogeneous diseases dominated by FRDA. Several of the recently identified ARCAs, such as AVED, ARSACS, AOA1, AOA2 and MSS, have a prevalence close to AT and should be searched for extensively irrespective of ethnic origins. The strategic scheme is a useful tool for the diagnosis of ARCAs in clinical practice.

Abstract
BACKGROUND To establish whether or not multiple sclerosis (MS) and neuromyelitis optica (NMO) are different pathological entities, we wondered whether MS patients and NMO patients share the same pattern of human leukocyte antigen (HLA) predisposition. OBJECTIVE To study a putative association between susceptibility to NMO and HLA class I or class II loci in Caucasians. METHODS A total of 39 unrelated Caucasian patients with NMO and six patients at a high risk of converting to NMO were studied. DNA genotyping of HLA class I and class II loci was assessed and allelic frequencies were reported at a high-resolution level. A case-control study by comparing the allelic distribution in the NMO patients with that of a French Caucasian MS group and a French Caucasian healthy group was carried out. RESULTS The frequencies of HLA-DQA1, DQB1, and HLA-DRB1 DR2 alleles in the NMO group were intermediate between the healthy control group and the MS group. The DPB1*0501 allele was not increased in the NMO group compared with the healthy control group. The distribution of HLA-DRB1 allele enabled to distinguish between NMO-IgG-positive patients and healthy controls (P = 0.01). NMO-IgG-negative patients presented an HLA II pattern closer to that of the MS group (P = 0.01). CONCLUSION In contrast to the reported results in Asian opticospinal MS, we found no association between the DPB1*0501 allele and NMO in our Caucasian patients. Moreover, we suggest that NMO-IgG-positive patients could represent a distinct NMO group in terms of their genetic susceptibility.
