Objectives: Wake-up Stroke (WUS) accounts for about 25% of all ischemic strokes. Differences according to sex in the WUS subgroup has been poorly investigated so far, so we aimed to assess these differences by differentiating the enrolled population based on treatment administered., Materials & Methods: We retrospectively analysed clinical and imaging data of WUS patients admitted to our hospital between November 2013 and December 2018 dividing them in two groups: rTPA-treated and non-rTPA treated group. To point out outcome differences we evaluated: NIHSS at 7 days or at discharge, mRS at discharge and ΔNIHSS., Results: We enrolled 149 WUS patients, 74 rTPA treated and 75 non-rTPA treated. Among rTPA treated patients, time from last known well (LKW) to Emergency Department (ED) admission was longer in females than males (610 vs 454 min), while females had a higher ΔNIHSS than males (5 vs 3). Finally, among non-rTPA treated patients, females were older than males (85 vs 79 years), had a higher pre-admission mRS (although very low in both cases), had a longer length of stay (17 vs 13 days) and shown a higher NIHSS at discharge (4 vs 2) compared to males., Conclusions: Females not receiving thrombolytic treatment had worse functional outcome than males, showing a higher NIHSS at discharge but, in contrast, when treated with rTPA they showed better neurological recovery as measured by a greater ΔNIHSS. We emphasize the importance of a prompt recognition of WUS in females since they seem to benefit more from rTPA treatment., (© 2024. Fondazione Società Italiana di Neurologia.)

Background: Paraneoplastic neurological syndromes (PNS) associated with lymphoma are rare diseases that usually have different peculiar features when compared to PNS associated with solid neoplasms., Methods: We retrospectively identified patients with NHL-associated PNS. Clinical and demographic data are reported., Results: We report two cases of NHL-associated PNS: a 72-years old female that presented with rapidly progressive cerebellar syndrome (RCPS) and a 65-years old male that presented with encephalomyelitis (confusion, sensory neuropathy, lower motor neuron involvement). Both PNS were associated with a NHL, small lymphocytic lymphoma and nodal marginal zone lymphoma respectively, and onconeural antibodies tested negative. All patients received first-line immunotherapy with absent or minimal benefit and died of intercurrent infection before cancer or immunosuppressive treatment., Discussion: RCPS and encephalomyelitis rarely present in association with NHL. In our cases, those syndromes took place in the setting of non-aggressive advanced hematological disorders, had an unfavorable prognosis with minimal benefit from immunotherapy, and were seronegative for onconeural antibodies. Our patients fulfilled the criteria for "definite PNS" in the 2004 PNS criteria, but they would be classified as "probable", in the new 2021 PNS criteria. The newest criteria rely on onconeural antibodies testing and on the evidence of antigen expression in cancer cells, features that are usually absent in NHL-associated PNS. New antibodies are being discovered but are still not available to promptly test yet., Conclusion: NHL-associated PNS are rare and bear unfavorable prognosis. The diagnosis should not be overlooked even in seronegative patients., (© 2021. Fondazione Società Italiana di Neurologia.)

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., (© 2021. The Author(s).)
