ObjectiveTo report clinical and laboratory characteristics, as well as treatment and clinical outcomes of patients admitted for neurologic diseases with and without COVID-19.MethodsIn this retrospective, single center cohort study, we included all adult inpatients with confirmed COVID-19, admitted to a Neuro-COVID Unit from February 21, 2020, who had been discharged or died by April 5, 2020. Demographic, clinical, treatment, and laboratory data were extracted from medical records and compared (FDR-corrected) to those of neurologic patients without COVID-19 admitted in the same period.ResultsOne hundred seventy-three patients were included in this study, of whom 56 were positive for COVID-19 while 117 were negative for COVID-19. Patients with COVID-19 were older (77.0, IQR 67.0–83.8 vs 70.1, IQR 52.9–78.6, p = 0.006), had a different distribution regarding admission diagnoses, including cerebrovascular disorders (n = 43, 76.8% vs n = 68, 58.1%), and had a higher quick Sequential Organ Failure Assessment (qSOFA) score on admission (0.5, IQR 0.4–0.6 vs 0.9, IQR 0.7–1.1, p = 0.006). In-hospital mortality rates (n = 21, 37.5% vs n = 5, 4.3%, p < 0.001) and incident delirium (n = 15, 26.8% vs n = 9, 7.7%, p = 0.003) were significantly higher in the COVID-19 group. COVID-19 and non-COVID patients with stroke had similar baseline characteristics but patients with COVID-19 had higher modified Rankin scale scores at discharge (5.0, IQR 2.0–6.0 vs 2.0, IQR 1.0–3.0, p < 0.001), with a significantly lower number of patients with a good outcome (n = 11, 25.6% vs n = 48, 70.6%, p < 0.001). In patients with COVID-19, multivariable regressions showed increasing odds of in-hospital death associated with higher qSOFA scores (OR 4.47, 95% CI 1.21–16.5; p = 0.025), lower platelet count (0.98, 0.97–0.99; p = 0.005) and higher lactate dehydrogenase (1.01, 1.00–1.03; p = 0.009) on admission.ConclusionsCOVID-19 patients admitted with neurologic disease, including stroke, have a significantly higher in-hospital mortality, incident delirium and higher disability than patients without COVID-19.
Background Several preclinical and clinical investigations have argued for nervous system involvement in SARS-CoV-2 infection. Some sparse case reports have described various forms of encephalitis in COVID-19 disease, but very few data have focused on clinical presentations, clinical course, response to treatment and outcomes. Methods The ENCOVID multicentre study included patients with encephalitis with full infectious screening, CSF, EEG, MRI data and confirmed SARS-CoV-2 infection recruited from 13 centres in northern Italy. Clinical presentation and laboratory markers, severity of COVID-19 disease, response to treatment and outcomes were recorded. Results twenty-five cases of encephalitis positive for SARS-CoV-2 infection were included. CSF showed hyperproteinorrachia and/or pleocytosis in 68% of cases whereas SARS-CoV-2 RNA by RT-PCR resulted negative. Based on MRI, cases were classified as ADEM (n=3), limbic encephalitis (LE, n=2), encephalitis with normal imaging (n=13) and encephalitis with MRI alterations (n=7). ADEM and LE cases showed a delayed onset compared to the other encephalitis (p=0.001) and were associated with previous more severe COVID-19 respiratory involvement. Patients with MRI alterations exhibited worse response to treatment and final outcomes compared to other encephalitis. Conclusions SARS-CoV-2 infection is associated with a wide spectrum of encephalitis characterized by different clinical presentation, response to treatment and outcomes.
Objectives-To investigate the safety and eYcacy of ultrasound guided botulinum toxin type A (BTX-A) injections into salivary glands for the treatment of sialorrhoea in patients with neurological disorders. Methods-The parotid and submandibular glands of 10 patients were injected with BTX-A using ultrasound guidance. Before injection, the baseline rate of salivation was assessed using a visual analogue scale. Postinjection, assessments were repeated at regular intervals for up to 1 year. Results-Of the 10 patients treated, nine (90%) reported a subjective reduction in salivation post-treatment and one patient (10%) found no improvement. Visual analogue scale scores showed a reduction of 55% in the mean rate of salivation for all patients and a reduction of 60.8% for the group of responders. No serious adverse events occurred and no procedure related complications were reported. Conclusions-This is the first study to report (1) the injection of BTX-A (BO-TOX ® ) into both parotid and submandibular glands, and (2) the use of ultrasound guidance during the administration of BTX-A into salivary glands. The results suggest that the technique is safe and that BTX-A injections are eVective for the treatment of sialorrhoea in patients with neurological disorders.

Background-Data on long-term risk and predictors of recurrent thrombotic events after ischemic stroke at a young age are limited. Methods and Results-We followed 1867 patients with first-ever ischemic stroke who were 18 to 45 years of age (mean age, 36.8±7.1 years; women, 49.0%), as part of the Italian Project on Stroke in Young Adults (IPSYS). Median follow-up was 40 months (25th to 75th percentile, 53). The primary end point was a composite of ischemic stroke, transient ischemic attack, myocardial infarction, or other arterial events. One hundred sixty-three patients had recurrent thrombotic events (average rate, 2.26 per 100 person-years at risk). At 10 years, cumulative risk was 14.7% (95% confidence interval, 12.2%-17.9%) for primary end point, 14.0% (95% confidence interval, 11.4%-17.1%) for brain ischemia, and 0.7% (95% confidence interval, 0.4%-1.3%) for myocardial infarction or other arterial events. Familial history of stroke, migraine with aura, circulating antiphospholipid antibodies, discontinuation of antiplatelet and antihypertensive medications, and any increase of 1 traditional vascular risk factor were independent predictors of the composite end point in multivariable Cox proportional hazards analysis. A point-scoring system for each variable was generated by their β-coefficients, and a predictive score (IPSYS score) was calculated as the sum of the weighted scores. The area under the receiver operating characteristic curve of the 0-to 5-year score was 0.66 (95% confidence interval, 0.61-0.71; mean, 10-fold internally cross-validated area under the receiver operating characteristic curve, 0.65).© 2014 American Heart Association, Inc. 1 Although it is well documented that such a risk is much lower in young patients with stroke than in elderly patients, information on what specific factors may predict recurrent events in younger age groups are limited. Most data derive from single-center studies enrolling several hundred patients or less, 2 using different thresholds of age to define young, and sometimes being biased by the inadequate capture of cases, the inclusion of different ethnic groups, and the high number of patients lost to follow-up.3 This makes such studies somewhat heterogeneous and their findings poorly comparable. In addition, the influential effect of some specific factors is missing in most previous studies. This is the case, for example, of patients' adherence to secondary prevention therapies, which is likely to impact the recurrence of potentially avoidable vascular events. The Italian Project on Stroke in Young Adults (IPSYS) provides the opportunity to investigate these issues owing to its large sample size, the homogeneous demographic characteristics and clinical phenotype of the subjects included, and the standard diagnostic workup. Therefore, in the present study we aimed at (1) elucidating the predictors of long-term recurrent vascular events after first-ever IS, and the extent to which these factors can be modified, which implicates the potential of reducing this risk,...
