RESUMO
BACKGROUND: In the general population, maternal SARS-CoV-2 infection during pregnancy is associated with worse maternal outcomes; however, only one study so far has evaluated COVID-19 clinical outcomes in pregnant and postpartum women with multiple sclerosis, showing no higher risk for poor COVID-19 outcomes in these patients. OBJECTIVE: In this multicenter study, we aimed to evaluate COVID-19 clinical outcomes in pregnant patients with multiple sclerosis. METHODS: We recruited 85 pregnant patients with multiple sclerosis who contracted COVID-19 after conception and were prospectively followed-up in Italian and Turkish Centers, in the period 2020-2022. A control group of 1354 women was extracted from the database of the Multiple Sclerosis and COVID-19 (MuSC-19). Univariate and subsequent logistic regression models were fitted to search for risk factors associated with severe COVID-19 course (at least one outcome among hospitalization, intensive care unit [ICU] admission and death). RESULTS: In the multivariable analysis, independent predictors of severe COVID-19 were age, body mass index ⩾ 30, treatment with anti-CD20 and recent use of methylprednisolone. Vaccination before infection was a protective factor. Vaccination before infection was a protective factor. Pregnancy was not a risk nor a protective factor for severe COVID-19 course. CONCLUSION: Our data show no significant increase of severe COVID-19 outcomes in patients with multiple sclerosis who contracted the infection during pregnancy.

The aim of this study is to assess changes in the body distribution and the semeiology of functional motor disorder (FMD) in patients who reported only one or more than one body site affected at FMD onset. Data were obtained from the Italian Registry of Functional Motor Disorders, which included patients with a diagnosis of clinically definite FMDs. The relationship between FMD features and spread to other body sites was estimated by multivariate Cox regression analysis. We identified 201 (49%) patients who reported only one body site affected at FMD onset and 209 (51%) who reported multiple body sites affected at onset. FMD spread from the initial site to another site in 43/201 (21.4%) patients over 5.7 ± 7.1 years in those with only one site affected at FMD onset; FMD spread to an another body site in 29/209 (13.8%) over 5.5 ± 6.5 years. The spread of FMD was associated with non-motor functional symptoms and psychiatric comorbidities only in the patients with one body site affected at FMD onset. Our findings provide novel insight into the natural history of FMD. The number of body sites affected at onset does not seem to have a consistent influence on the risk of spread. Furthermore, our findings suggest that psychiatric comorbidities and non-motor functional symptoms may predict the spread of FMD symptoms, at least in patients with one body site affected at onset.

BACKGROUND: Efficiency of care chain response and hospital reactivity were and are challenged for stroke acute care management during the pandemic period of coronavirus disease 2019 (COVID-19) in North-Eastern Italy (Veneto, Friuli-Venezia-Giulia, Trentino-Alto-Adige), counting 7,193,880 inhabitants (ISTAT), with consequences in acute treatment for patients with ischemic stroke. METHODS: We conducted a retrospective data collection of patients admitted to stroke units eventually treated with thrombolysis and thrombectomy, ranging from January to May 2020 from the beginning to the end of the main first pandemic period of COVID-19 in Italy. The primary endpoint was the number of patients arriving to these stroke units, and secondary endpoints were the number of thrombolysis and/or thrombectomy. Chi-square analysis was used on all patients; furthermore, patients were divided into two cohorts (pre-lockdown and lockdown periods) and the Kruskal-Wallis test was used to test differences on admission and reperfusive therapies. RESULTS: In total, 2536 patients were included in 22 centers. There was a significant decrease of admissions in April compared to January. Furthermore, we observed a significant decrease of thrombectomy during the lockdown period, while thrombolysis rate was unaffected in the same interval across all centers. CONCLUSIONS: Our study confirmed a decrease in admission rate of stroke patients in a large area of northern Italy during the lockdown period, especially during the first dramatic phase. Overall, there was no decrease in thrombolysis rate, confirming an effect of emergency care system for stroke patients. Instead, the significant decrease in thrombectomy rate during lockdown addresses some considerations of local and regional stroke networks during COVID-19 pandemic evolution.

INTRODUCTION: Gait and mobility impairment are pivotal signs of parkinsonism, and they are particularly severe in atypical parkinsonian disorders including multiple system atrophy (MSA) and progressive supranuclear palsy (PSP). A pilot study demonstrated a significant improvement of gait in patients with MSA of parkinsonian type (MSA-P) after physiotherapy and matching home-based exercise, as reflected by sensor-based gait parameters. In this study, we aim to investigate whether a gait-focused physiotherapy (GPT) and matching home-based exercise lead to a greater improvement of gait performance compared with a standard physiotherapy/home-based exercise programme (standard physiotherapy, SPT). METHODS AND ANALYSIS: This protocol was deployed to evaluate the effects of a GPT versus an active control undergoing SPT and matching home-based exercise with regard to laboratory gait parameters, physical activity measures and clinical scales in patients with Parkinson's disease (PD), MSA-P and PSP. The primary outcomes of the trial are sensor-based laboratory gait parameters, while the secondary outcome measures comprise real-world derived parameters, clinical rating scales and patient questionnaires. We aim to enrol 48 patients per disease group into this double-blind, randomised-controlled trial. The study starts with a 1 week wearable sensor-based monitoring of physical activity. After randomisation, patients undergo a 2 week daily inpatient physiotherapy, followed by 5 week matching unsupervised home-based training. A 1 week physical activity monitoring is repeated during the last week of intervention. ETHICS AND DISSEMINATION: This study, registered as 'Mobility in Atypical Parkinsonism: a Trial of Physiotherapy (Mobility_APP)' at clinicaltrials.gov (NCT04608604), received ethics approval by local committees of the involved centres. The patient's recruitment takes place at the Movement Disorders Units of Innsbruck (Austria), Erlangen (Germany), Lausanne (Switzerland), Luxembourg (Luxembourg) and Bolzano (Italy). The data resulting from this project will be submitted to peer-reviewed journals, presented at international congresses and made publicly available at the end of the trial. TRIAL REGISTRATION NUMBER: NCT04608604.

BACKGROUND: Functional motor disorders (FMD) are a frequent neurological condition affecting patients with movement disorders. Commonly described in younger adults, their manifestation can be also associated to an elderly onset. OBJECTIVE: To assess the prevalence and describe the clinical manifestations of FMD with elderly and younger onset and their relationship with demographical and clinical variables. METHODS: We recruited patients with a "clinically definite" diagnosis of FMD from the Italian Registry of FMD. Patients underwent extensive clinical assessments. For elderly onset, we set a chronological cut-off at 65 years or older according to WHO definition. Multivariate regression models were implemented to estimate adjusted odds ratio of elderly FMD onset related to clinical characteristics. RESULTS: Among the 410 patients, 34 (8.2%) experienced elderly-onset FMD, with a mean age at onset of 70.9 years. The most common phenotype was tremor (47.1%), followed by gait disorders, weakness, and dystonia (29.4%, 23.5%, 14.7%, respectively). Eleven elderly patients had a combined phenomenology: 9 exhibited two phenotypes, 2 had three phenotypes. Weakness was isolated in 3/8 patients and combined with another phenotype in 5/8, manifesting as paraplegia (n = 4); upper limb diplegia (n = 2), hemiparesis/hemiplegia (n = 1), and tetraparesis/tetraplegia (n= 1). Non-motor and other functional neurological disorders occurred more frequently in the younger group (89.1%) than the elderly (73.5%). Neurological and non-neurological comorbidities were more prevalent in the elderly group (82.4%) as opposed to the younger (32.7%). In a multivariate regression analysis, elderly-onset FMD was significantly associated with neurological comorbidities, including parkinsonism (OR 6.73) and cerebrovascular diseases (OR 5.48). CONCLUSIONS: These results highlight the importance of achieving an accurate diagnosis of FMD in the elderly, as it is crucial for effectively managing FMD symptoms and addressing neurological comorbidities.

INTRODUCTION: This work aims to assess lower limb free flaps spontaneous sensory recovery by comparing and analyzing a single standardized reconstructive procedure, namely the free noninnervated anterolateral thigh (ALT) flap in order to evaluate which flap or patient-related factors may predict flap reinnervation. METHODS: Between January 2010 and March 2018 all nonreinnervated ALT flaps for lower limb coverage performed at our institution were screened. We excluded from the study flaps with less than 18 months of follow-up time, neurotized flaps, and those from patients who missed the last follow up. Sensory modalities that were evaluated included the two-point discrimination (2PD) test, measured in mm; and the Semmes-Weinstein monofilament (SWM) test, measured in gram. The sensory parameter results were compared and analyzed according to flap size (two groups; <160 cm2 vs. > 160 cm2), and post-op time of testing (two groups; <18-28 months vs. > 28 months). RESULTS: Twenty-one ALT free flaps were finally retained by this study. Our findings showed that flaps of smaller surface area showed a significantly better return in sensory discrimination 2PD and in sensory cutaneous pressure perception SWM testing. CONCLUSION: This work establishes for the first time some key quantitative data that can help predict free flap spontaneous reinnervation outcomes when using the same ALT flap. In our series, flaps surface remains the main discriminant value for a better sensory recovery.

BACKGROUND: Functional neurological disorders (FND) are disabling medical conditions commonly seen in neurological practice. Neurologists play an essential role in managing FND, from establishing a diagnosis to coordination of multidisciplinary team-based treatment for patients. With this study, we investigated the knowledge and the clinical experience of Italian neurologists in managing patients with FND. METHODS: Members of the Italian Society of Neurology were invited via e-mail to participate in this ad hoc online survey; 492 questionnaires were returned completed. RESULTS: The term "Functional neurological disorders" in reference to FND was used more frequently than other psychological (e.g., psychogenic or conversion), or descriptive terms (e.g., non-organic or stress-related). When speaking with patients, the respondents stated that they preferred explaining symptoms based on abnormal functioning of the nervous system than discussing mental illness and that they would refer their patient to a psychologist rather than to a psychiatrist. Few considered that physiotherapy and psychiatric interventions are useful approaches to treating FND. Some believed that patients simulate their symptoms. CONCLUSIONS: Overall, the responses suggest that knowledge about scientific advances in FND is somewhat sparse. A psychiatric-centered view of FND opens the way to an approach in which neurobiological and psychological aspects constitute essential factors of the condition. In this context, professional education could improve understanding of FND and optimize patient management.

INTRODUCTION: Functional motor disorders (FMDs) are usually categorized according to the predominant phenomenology; however, it is unclear whether this phenotypic classification mirrors the underlying pathophysiologic mechanisms. OBJECTIVE: To compare the characteristics of patients with different FMDs phenotypes and without co-morbid neurological disorders, aiming to answer the question of whether they represent different expressions of the same disorder or reflect distinct entities. METHODS: Consecutive outpatients with a clinically definite diagnosis of FMDs were included in the Italian registry of functional motor disorders (IRFMD), a multicenter data collection platform gathering several clinical and demographic variables. To the aim of the current work, data of patients with isolated FMDs were extracted. RESULTS: A total of 176 patients were included: 58 with weakness, 40 with tremor, 38 with dystonia, 23 with jerks/facial FMDs, and 17 with gait disorders. Patients with tremor and gait disorders were older than the others. Patients with functional weakness had more commonly an acute onset (87.9%) than patients with tremor and gait disorders, a shorter time lag from symptoms onset and FMDs diagnosis (2.9 ± 3.5 years) than patients with dystonia, and had more frequently associated functional sensory symptoms (51.7%) than patients with tremor, dystonia and gait disorders. Patients with dystonia complained more often of associated pain (47.4%) than patients with tremor. No other differences were noted between groups in terms of other variables including associated functional neurological symptoms, psychiatric comorbidities, and predisposing or precipitating factors. CONCLUSIONS: Our data support the evidence of a large overlap between FMD phenotypes.

OBJECTIVE: We aimed to describe the prevalence and clinical-demographical features of patients with functional gait disorders (FGDs) and to compare them to patients with functional motor disorders (FMDs) without FGDs (No-FGDs). METHODS: In this multicenter observational study, we enrolled patients with a clinically definite diagnosis of FMDs in 25 tertiary movement disorders centers in Italy. Each subject with FMDs underwent a comprehensive clinical assessment, including screening for different subtypes of functional gait disorders. Multivariate regression models were implemented in order to estimate the adjusted odds ratio (OR; 95% confidence interval) of having FGDs in relation to sociodemographic and clinical characteristics. RESULTS: Out of 410 FMDs, 26.6% (n = 109) of patients exhibited FGDs. The most frequent FGDs were slow gait (n = 43, 39.4%), astasia-abasia (n = 26, 23.8%), and knee buckling (n = 24, 22%). They exhibited single FGDs in 51.4% (n = 56) or complex FGDs (more than one type of FGDs) in 48.6% (n = 53) of cases. On multivariate regression analysis, the presence of FGDs was more likely associated with older age (OR 1.03, 95% CI 1.01-1.04), functional visual symptoms (OR 2.19, 95% CI 1.08-4.45), and the diagnosis of somatic symptoms disorder (OR 2.97, 95% CI 1.08-8.17). FGDs were also more likely to undergo physiotherapy (OR 1.81, 95% CI 1.08-3.03). CONCLUSIONS: People with FMDs may present with different and overlapping types of FGDs, which may occur in older age. The association of FGDs with functional visual symptoms and somatic symptoms disorder opens up to new avenues to the understanding of the neural mechanisms of these disorders.

One of the best characterized autoimmune encephalitis is the Anti-Nmethyl- D-aspartate receptor (NMDAR) encephalitis, which may occur in the presence of cancer. First- and second-line immunotherapy and oncological investigations are suggested. We present here a case of an 18-year-old female who was our first patient suffering from Anti- NMDAR encephalitis more than 9 years ago. She was satisfactorily treated with intravenous immunoglobulins and high dose steroid therapy. After more than one year the patient had a relapse. First-line immunotherapy was repeated; however, a complete recovery was achieved only after plasmapheresis. Afterwards, she continued maintenance immunotherapy with steroids for two years and with Azathioprine for about five years associated to regular oncological assessment. In the last years our therapeutical approach of Anti-NMDARencephalitis has significantly changed. Nevertheless, established treatment guidelines are still missing and the role of long-term maintenance immunotherapy is largely unexplored. In addition, oncological revaluation might be indicated in selected patients.
RESUMO
Background. Delta-9-tetrahydrocannabinol (THC)/cannabidiol (CBD) (nabiximols or Sativex®) is an oromucosal spray formulation containing THC and CBD at an approximately 1:1 fixed ratio. Its administration for the treatment of pain in patients with multiple sclerosis (MS) has been established. MS patients generally complain of different kinds of pain, including spasticity-related and neuropathic pain. In this study, we compared and evaluated pain modulation and thermal/pain threshold of MS patients before and after THC/CBD administration. Methods. 19 MS patients underwent clinical examination, numerical rating scale (NRS), quantitative sensory testing (QST), and laser-evoked potentials (LEPs) before and after 1 month of therapy. Psychophysiological and neurophysiological data were compared to sex- and age-matched controls. Results. Patients reported a significant reduction in pain. We found statistically significant differences in LEP parameters between patients and controls but no significant change in LEP measures after THC/CBD therapy. Cold and heat detection thresholds were altered in patients but did not change after THC/CBD therapy. There was a significant increase in cold pain threshold by hand stimulation and a significant reduction in abnormal cold perception thresholds. Conclusions. Our results indicate that Sativex® therapy provides pain relief in MS patients and suggest that it might modulate peripheral cold-sensitive TRP channels.
RESUMO
BACKGROUND: Delta-9-tetrahydrocannabinol and cannabidiol (THC:CBD) oromucosal spray (Sativex®) has been recently approved for the management of treatment-resistant multiple sclerosis (MS) spasticity. Although the symptomatic relief of Sativex® on MS-spasticity has been consistently demonstrated, the pathogenetic implications remain unclear and the few electrophysiological studies performed to address this topic yielded controversial results. We therefore aimed to investigate the mechanisms underpinning the modulation of spastic hypertonia by Sativex®, at both central and spinal levels, through an extensive neurophysiological battery in patients with MS. METHODS: Nineteen MS patients with treatment-resistant spasticity were recruited. Before and after 4weeks of treatment with Sativex® patients were clinically assessed with the Modified Ashworth Scale (MAS) and underwent a large neurophysiological protocol targeting measures of excitability and inhibition at both cortical [e.g., intracortical facilitation (ICF), short (SICI) and long (LICI) intracortical inhibition, cortical silent period (CSP)] and spinal level [e.g., H-reflex, H/M ratio and recovery curve of the H-reflex (HRC)]. A group of 19 healthy subjects served as controls. RESULTS: A significant reduction of the MAS score after 4weeks of Sativex® treatment was detected. Before treatment, an increase in the late facilitatory phase of HRC was recorded in patients compared to the control group, that normalised post treatment. At central level, SICI and LICI were significantly higher in patients compared to healthy subjects. After therapy, a significant strengthening of inhibition (e.g. reduced LICI) and a non-significant facilitation (e.g. marginally increased ICF) occurred, suggesting a modulatory effect of Sativex® on different pathways, predominantly of inhibitory type. Sativex® treatment was well tolerated, with only 3 patients complaining about dizziness and bitter taste in their mouth. DISCUSSION: Our results confirm the clinical benefit of Sativex® on spastic hypertonia and demonstrate that it might modulate both cortical and spinal circuits, arguably in terms of both excitation and inhibition. We suggest that the clinical benefit was likely related to a net increase of inhibition at cortical level that, in turn, might have influenced spinal excitability.
