Pontine warning syndrome and restless legs syndrome secondary to paramedian pontine infarction: a case report.

Pontine warning syndrome (PWS) occurs rarely and is characterized by recurrent, stereotyped episodes of motor or sensory dysfunction, dysarthria, or ophthalmoplegia leading to pontine infarction. Restless legs syndrome (RLS) is a distinct neurological sensorimotor disorder. Pontine infarction is a rare but possible cause of RLS. Here, we report the case of a 58-year-old woman who experienced unilateral RLS in concomitance with stereotyped episodes of left-sided weakness and dysarthria, and developed an acute paramedian pontine infarction eventually. To the best of our knowledge, no other cases of PWS coinciding with RLS in the progression of pontine infarction have been reported in the literature. Furthermore, we discussed the potential mechanisms of PWS and RLS secondary to pontine infarction, which may be helpful for managing such patients.

Clinical efficacy of Danzhi Xiaoyao Powder in the treatment of post-stroke depression: A protocol for randomized, double-blind clinical study.

BACKGROUND: Depression is a common complication after stroke and is closely related to the poor prognosis of stroke. Antidepressants are the priority drug in the treatment of post-stroke depression (PSD), but there are dependence and adverse reactions. Danzhi Xiaoyao Powder has a good effect on depression without obvious adverse reactions. At present, there is a lack of rigorous randomized controlled trials to evaluate the clinical efficacy of Danzhi Xiaoyao Powder in the treatment of PSD. METHODS: This is a prospective, randomized, double-blind, parallel controlled trial to explore the efficacy and safety of Danzhi Xiaoyao Powder in the treatment of PSD. The participants were randomly divided into treatment group and control group. The treatment group used Danzhi Xiaoyao Powder combined with escitalopram oxalate, and the control group used Danzhi Xiaoyao Powder simulant combined with citalopram oxalate. The two groups were both treated for 8 weeks and followed up for 3 months. Observational index includes: Total response rate, Hamilton depression scale, Barthel index, national institutes of health stroke scale, the modified Edinburgh-Scandinavian stroke scale, Incidence of adverse reactions. Finally, SPASS 22.0 software was used for statistical analysis of the data. DISCUSSION: This study will evaluate the clinical efficacy of Danzhi Xiaoyao Powder in the treatment of PSD. The results of this study will provide reliable evidence for the clinical use of Xiaoyao Powder in the treatment of PSD.

The efficacy and risk factors of mechanical thrombectomy for the treatment of vertebrobasilar artery occlusion: a single center study.

BACKGROUND: The mortality of acute ischemic stroke patients caused by vertebrobasilar artery occlusion (VBAO) is high and mechanical thrombectomy has gradually become a promising treatment for acute ischemic stroke. This study analyzed the efficacy of mechanical thrombectomy and the risk factors associated with poor outcomes in VBAO patients caused by severe local atherosclerotic stenosis. METHODS: This retrospective study enrolled patients with acute ischemic stroke caused by VBAO between March 1, 2016 and August 31, 2019. Patient demographic and clinical data were collected retrospectively. All enrolled patients were retrospectively interviewed for at least 3 months. Patients with a modified Rankin scale (mRS) score between 0 and 3 points were defined as having satisfactory outcomes while those with more than 3 points were defined as having unsatisfactory outcomes. In-hospital mortality, the rates of recanalization, and the rates of intracerebral hemorrhage were also recorded. Multivariable logistic regression was used to determine the risk factors of unsatisfactory outcomes in enrolled patients. RESULTS: A total of 65 patients were enrolled in this study with a median age 69.0 (63.0-78.0) years and 48 patients (73.8%) were male. Approximately 50% of patients had a mRS score of 0 or 1 point within 90 days after treatment with mechanical thrombectomy and 14 patients had a mRS score of 6 points. A total of 11 patients died in hospital. Out of the 65 patients, 7 required recanalization and 9 patients suffered from intracerebral hemorrhage. Multivariate logistic regression analysis showed that older age, lower baseline posterior circulation acute stroke prognosis early CT score (pcASPECTS), higher baseline National Institutes of Health stroke scale (NIHSS) score, and residual stenosis were independent risk factors of both unsatisfactory outcomes and mortality of VBAO patients. CONCLUSIONS: This study confirmed the important role of mechanical thrombectomy in the treatment of acute ischemic stroke caused by VBAO and may provide some guidance for improving the prognosis of patients.

Elevated Total Homocysteine Predicts In-Hospital Pneumonia and Poor Functional Outcomes in Acute Ischemic Stroke.

BACKGROUND: We investigated the association between elevated total homocysteine (tHcy) levels upon hospital admission and short-term in-hospital outcomes, including pneumonia in acute ischemic stroke (AIS) patients. METHODS: A total of 2,084 AIS patients enrolled from December 2013 to May 2014 across 22 hospitals in Suzhou city were included in the present study. We divided patients into four groups according to their level of admission tHcy: quartile (Q1) (<9.70 umol/L), Q2 (9.70-12.3 umol/L), Q3 (12.3-16.9 umol/L), and Q4 (≥16.9 umol/L). Logistic regression models were used to estimate the effect of tHcy on the short-term outcomes, including in-hospital pneumonia, all-cause in-hospital mortality, and poor outcome upon discharge (modified Rankin Scale score ≥3) in AIS patients. RESULTS: The risk of in-hospital pneumonia was significantly higher in patients with the highest tHcy level (Q4) compared to those with the lowest tHcy level (Q1) (adjusted odds ratio [OR] 1.55; 95% confidence interval [CI], 1.03-2.33; P-trend =0.019). The highest tHcy level (Q4) was associated with a 3.35-fold and 1.50-fold increase in the risk of in-hospital mortality (OR 3.35; 95% CI, 1.11-10.13; P-trend =0.015) and poor outcome upon discharge (OR 1.50; 95% CI, 1.06-2.12; Ptrend =0.044) in comparison to Q1 after adjustment for potential covariates including pneumonia. CONCLUSION: Having a high admission tHcy level was independently associated with in-hospital pneumonia, in-hospital mortality, and poor outcome upon discharge in AIS patients.
