RESUMO
A few earlier observations and recent controlled studies pointed to the possible contribution of thyroid diseases in idiopathic adult-onset dystonia (IAOD). The aim of this study was to investigate the association between thyroid status and clinical characteristics of IAOD, focusing on dystonia localization, spread, and associated features such as tremors and sensory tricks. Patients were identified from those included in the Italian Dystonia Registry, a multicentre dataset of patients with adult-onset dystonia. The study population included 1518 IAOD patients. Patients with hypothyroidism and hyperthyroidism were compared with those without any thyroid disease. In the 1518 IAOD patients, 167 patients (11%; 95% CI 9.5-12.6%) were diagnosed with hypothyroidism and 42 (2.8%; 95% CI 1.99-3.74) with hyperthyroidism. The three groups were comparable in age at dystonia onset, but there were more women than men in the groups with thyroid disease. Analysing the anatomical distribution of dystonia, more patients with blepharospasm were present in the hyperthyroidism group, but the difference did not reach statistical significance after the Bonferroni correction. The remaining dystonia-affected body sites were similarly distributed in the three groups, as did dystonia-associated features and spread. Our findings provided novel information indicating that the high rate of thyroid diseases is not specific for any specific dystonia subpopulation and does not appear to influence the natural history of the disease.

OBJECTIVE: To estimate the incidence and describe clinical characteristics and outcome of GBS in COVID-19 patients (COVID19-GBS) in one of the most hit regions during the first pandemic wave, Lombardia. METHODS: Adult patients admitted to 20 Neurological Units between 1/3-30/4/2020 with COVID19-GBS were included as part of a multi-center study organized by the Italian society of Hospital Neuroscience (SNO). RESULTS: Thirty-eight COVID19-GBS patients had a mean age of 60.7 years and male frequency of 86.8%. CSF albuminocytological dissociation was detected in 71.4%, and PCR for SARS-CoV-2 was negative in 19 tested patients. Based on neurophysiology, 81.8% of patients had a diagnosis of AIDP, 12.1% of AMSAN, and 6.1% of AMAN. The course was favorable in 76.3% of patients, stable in 10.5%, while 13.2% worsened, of which 3 died. The estimated occurrence rate in Lombardia ranges from 0.5 to 0.05 GBS cases per 1000 COVID-19 infections depending on whether you consider positive cases or estimated seropositive cases. When we compared GBS cases with the pre-pandemic period, we found a reduction of cases from 165 to 135 cases in the 2-month study period in Lombardia. CONCLUSIONS: We detected an increased incidence of GBS in COVID-19 patients which can reflect a higher risk of GBS in COVID-19 patients and a reduction of GBS events during the pandemic period possibly due to a lower spread of more common respiratory infectious diseases determined by an increased use of preventive measures.

A wide range of neurological manifestations have been reported during the COVID-19 pandemic, including a variety of Parkinsonian cases. The association of numerous viruses with the development of persistent or transient Parkinsonism has been well-documented. We observed a patient who developed a levodopa non-responsive Parkinsonian syndrome with dysautonomia during a prolonged stay at home for COVID-19. Although the temporal proximity of the emerging Parkinsonian features with a COVID-19 diagnosis suggested a causal relationship, we considered the possibility of a coincidental occurrence of multiple system atrophy. We discuss the patient's clinical features in relation to the established clinical diagnostic criteria and review differential diagnoses as well as the role of SARS-CoV-2 infection.
RESUMO
INTRODUCTION: Cervical dystonia (CD) is the most common form of adult-onset focal dystonia. Because of a heterogeneous clinical presentation, the diagnosis rests on clinical opinion. During the last decades, several clinical trials have tested safety and efficacy of medical and surgical treatments for CD. We analyzed all the published CD trials and reviewed the strategies adopted for patient enrollment. METHODS: The review included clinical trials in patients with CD published in PubMed. Studies were excluded if reviews, meta-analyses, post-hoc analyses on pooled data, or if not reporting a treatment for CD. RESULTS: A total of 174 articles were identified; 134 studies met inclusion criteria. Diagnosis of CD varied among studies and in most cases was based on clinical judgement, using different descriptors such as "cervical dystonia" (37 studies), "idiopathic or isolated CD" (35), "primary CD" (13), and "torticollis" (40). Clinical judgement was supported by a phenomenological description of dystonia in four studies, and by a specific diagnostic strategy in other four. Finally, one study adopted general diagnostic criteria for dystonia. Inclusion and exclusion criteria proved heterogeneous across trials and were defined only in 108 studies, mainly considering age or the phenomenological pattern of muscle involvement. CONCLUSION: The review showed lack of consolidated diagnostic criteria and non-uniformity of eligibility criteria for CD across clinical trials. There is need to move beyond clinical judgement as diagnostic criterion for selecting participants. New trials assessing specific CD patient subgroups or comparing medical and surgical procedures will need grounds that are more consistent.

OBJECTIVE: To assess the prevalence and phenomenology of Impulse control behavior (ICB) in Parkinson's disease (PD) patients carrying mutations in the ß-glucocerebrosidase (GBA) gene. BACKGROUND: GBA mutations are a common genetic factor predisposing to PD. ICB is among the most disabling non-motor complications of PD. The occurrence of ICB in PD patients carrying GBA gene mutations (GBA-PD) has not been yet established. METHODS: Forty-six patients with clinically definite PD (23 GBA-PD and 23 non-mutated patients, NM-PD) were screened for ICB. Diagnosis was clinically and rating based on a specific questionnaire (QUIP-RS). Other demographic and clinical variables did not differ between groups. RESULTS: ICB occurred more frequently in GBA-PD patients (52.2%) compared to NM-PD (13%) and the total QUIP-RS score was higher in the GBA-PD group. Hypersexuality and compulsive shopping were the most prevalent ICB types occurring in GBA patients. ICB occurred only in one GBA-PD patient on levodopa monotherapy and in 11 patients taking dopamine agonists, either monotherapy or combined with levodopa (the corresponding figures in NM-PD patients were 0 and 3). Most GBA-PD patients were heterozygous for two common genetic variants, without appreciable difference in their ICB profile. CONCLUSION: ICB is more common in GBA-PD patients compared to NM-PD. Dopamine agonist therapy may be synergic to GBA carrier status for ICB occurrence.

Cardiac conduction and/or rhythm abnormalities (CCRA) are the most frequent and life-threatening complications in DM1. In order to determine prevalence, incidence, characteristics, age of onset and predictors of CCRA, CCRA progression and sudden cardiac death (SCD) in DM1, we collected ECG/24hECG-Holter data from a yearly updated 34-year database of a cohort of 103 DM1 patients without cardiac abnormalities at baseline, followed for at least 1 year. Fifty-five patients developed CCRA [39 developed conduction abnormalities (CCA) and 16 rhythm abnormalities (CRA)], which progressed in 22. Nine had SCD. Risk and incidence of CCRA amounted to 53.4 and 6.83% person-years (CCA: 37.9 and 4.8%; CRA 15.5 and 2%), respectively; risk and incidence of SCD amounted to 8.74 and 0.67% person-years, respectively. CTG expansion represented a predictor of CCRA incidence (HR 1.10, p = 0.04), CCRA progression (HR 1.28, p = 0.001) and SCD (HR 1.39, p = 0.002). MIRS progression during follow-up was associated with CCRA prevalence (OR 5.82, p = 0.004); older age and larger CTG expansion to SCD prevalence (OR 2.67, p = 0.012; OR 1.54, p = 0.005). Age of CCRA onset and CCRA progression was significantly lower in patients with larger CTG expansion and in those with MIRS progression. Age when SCD occurred was significantly lower in patients with larger CTG expansion. Amongst recorded cardiac abnormalities, both atrial flutter (OR 8.70; p = 0.031) and paroxysmal supraventricular tachycardia (OR 8.67; p = 0.040) were associated with SCD. Although all DM1patients may develop cardiac abnormalities at any time in their life, patients older than 30 years with larger CTG expansion and MIRS progression in particular should be carefully monitored via periodical ECG.
