Peripheral facial palsy is a common clinical symptom and is most often caused by Bell's palsy. The pathogenesis is largely unknown, but inflammation of the facial nerve, possibly after a viral infection, may play a role. Bell's palsy has a monophasic course with usually - but not always - a good recovery. Even though Bell's palsy exhibits clear clinical features, in clinical practice diagnosis and choice of treatment remain difficult and other causes of an isolated facial palsy may easily be overlooked.

Background and Objectives: To explore clinical and safety outcomes of patients with acute ischemic stroke (AIS) and active cancer after endovascular treatment (EVT)., Methods: Using data from the Multicenter Randomized Clinical Trial of Endovascular Treatment for Acute Ischemic Stroke in the Netherlands (MR CLEAN) Registry, we compared patients with active cancer (defined as cancer diagnosed within 12 months before stroke, metastatic disease, or current cancer treatment) to patients without cancer. Outcomes were 90-day modified Rankin Scale (mRS) score, mortality, successful reperfusion (expanded Treatment in Cerebral Infarction score ≥2b), symptomatic intracranial hemorrhage (sICH), and recurrent stroke. Subgroup analyses were performed in patients with a prestroke mRS score of 0 or 1 and according to treatment setting (curative or palliative). Analyses were adjusted for prognostic variables., Results: Of 2,583 patients who underwent EVT, 124 (4.8%) had active cancer. They more often had prestroke disability (mRS score ≥2: 34.1% vs 16.6%). The treatment setting was palliative in 25.3% of the patients. There was a shift toward worse functional outcome at 90 days in patients with active cancer (adjusted common odds ratio [acOR] 2.2, 95% confidence interval [CI] 1.5-3.2). At 90 days, patients with active cancer were less often independent (mRS score 0-2: 22.6% vs 42.0%, adjusted OR [aOR] 0.5, 95% CI 0.3-0.8) and more often dead (52.2% vs 26.5%, aOR 3.2, 95% CI 2.1-4.9). Successful reperfusion (67.8% vs 60.5%, aOR 1.4, 95% CI 1.0-2.1) and sICH rates (6.5% vs 5.9%, aOR 1.1, 95% CI 0.5-2.3) did not differ. Recurrent stroke within 90 days was more common in patients with active cancer (4.0% vs 1.3%, aOR 3.1, 95% CI 1.2-8.1). The sensitivity analysis of patients with a prestroke mRS score of 0 or 1 showed that patients with active cancer still had a worse outcome at 90 days (acOR 1.9, 95% CI 1.2-3.0). Patients with active cancer in a palliative treatment setting regained functional independence less often compared to patients in a curative setting (18.2% vs 32.1%), and mortality was higher (81.8% vs 39.3%)., Discussion: Despite similar technical success, patients with active cancer had significantly worse outcomes after EVT for AIS. Moreover, they had an increased risk of recurrent stroke. Nevertheless, about a quarter of the patients regained functional independence, and the risk of other complications, most notably sICH, was not increased., Classification of Evidence: This study provides Class I evidence that patients with active cancer undergoing EVT for AIS have worse functional outcomes at 90 days compared to those without active cancer., (© 2022 American Academy of Neurology.)

A 60-year-old patient presented with respiratory distress, after recently being tested COVID-19 positive and was mechanically ventilated for 15 days. After cessation of sedation, he remained in deep comatose state, without any reaction on pain stimuli (Glasgow Coma Score 3). MRI of the brain showed diffuse leukoencephalopathy and multiple (>50) microbleeds. Diffuse COVID-19-associated leukoencephalopathy with microhaemorrhages is associated with a poor prognosis. However, 3 months later, our patient showed a remarkable recovery and was able to walk independently. This case report shows COVID-related leukoencephalopathy and intracerebral microbleeds, even with persistent comatose state, may have a favourable clinical outcome and prolonged treatment should be considered in individual cases., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2021.

Objective: Utilization is an executive function disorder and implies an inappropriate response to external stimuli. The sunglasses test is a simple test to examine utilization by offering a pair of sunglasses to a patient without any instruction., Patients and Methods: We performed a pilot study to examine the sunglasses test in 100 patients, of which 50 had cognitive symptoms and 50 did not have cognitive symptoms. When the patient put on the sunglasses, the test was considered positive. Cognitive dysfunction was based on the results of the MMSE, results of the clock test and neuropsychological examination (blinded). The final diagnosis was based on all results of the work-up (including MRI)., Results: Of the 50 patients with cognitive symptoms 30 had a positive test and 28 of them had cognitive dysfunction. Final diagnosis in most patients was Dementia due to probable Alzheimers disease, followed by Frontotemporal dementia. Seven of the 20 patients with a negative test also had cognitive dysfunction. None of the 50 patients without cognitive symptoms put on the sunglasses. Sensitivity of the sunglasses test to detect cognitive dysfunction was 80% and specificity was 97%, with a positive predictive value of 93%., Conclusion: Offering sunglasses is a simple test to screen for utilization. Putting on sunglasses without instruction to do so can be indicative for cognitive dysfunction and further cognitive evaluation should be considered. Future studies are needed in a larger group of patients and to determine the role of this test in different diseases with cognitive decline., (Copyright © 2018. Published by Elsevier B.V.)

Objective: To compare the diagnostic work-up and treatment strategy of Bell's palsy by: general practitioners (GPs); ear, nose and throat (ENT) specialists; and neurologists in the Netherlands., Design: Cross-sectional survey., Method: GPs, ENT specialists and neurologists were asked to participate in an online survey on the diagnosis and treatment of Bell's palsy. Results per specialty were analysed using descriptive statistics and chi-squared test., Results: A total of 415 clinicians participated, including 149 GPs, 123 ENT specialists, and 143 neurologists. The answers from the three disciplines showed significant differences concerning history taking, physical examination, alarm symptoms, treatment strategy and follow-up. ENT specialists more frequently asked about hearing loss (90%), whereas neurologists enquired about weakness in arms and legs (62%). GPs less often ask about tick bites than clinicians in ENT and neurology, respectively (36% vs. 89% and 71%). Neurologists rarely performed otoscopy (21%), but more frequently tested eye movements (78%) than GPs (33%) and ENT specialists (20%). Compared to GPs and neurologist, ENT specialists more frequently reported the supplementation of Prednisone treatment with antiviral agents (45% vs. 9% and 6 % resp.). Furthermore, the time interval to the follow-up visit varied strongly between clinicians, ranging between a few days to six weeks after the first clinic visit., Conclusion: This study shows that the diagnostic work-up and treatment strategy for Bell's palsy in the Netherlands is highly dependent on the clinician's specialty. Despite the fact that equivalent guidelines are in place, GPs, ENT specialists and neurologists gave different answers to questions concerning diagnostics and treatment. This finding suggests that more attention should be paid to the implementation of and adherence to the multidisciplinary guideline for Bell's palsy.

Objectives: Reducing the rate of postoperative stroke after cardiac surgery remains challenging, especially in patients with occlusive cerebrovascular disease. Angioplasty in all patients with high-grade carotid artery stenosis has not been shown to be effective in reducing the post-surgical stroke rate. In this study, we present the initial results of a different approach using selective carotid angioplasty only in patients with poor intracranial collaterals., Methods: We conducted a single-centre study to assess the safety of this procedure. The postangioplasty complication rate of the study group was compared to that of patients who were scheduled for symptomatic carotid artery angioplasty. To determine the effectiveness of this procedure, the post-cardiac surgery complication rate of the study group was compared with that of the matched case controls., Results: Twenty-two patients were treated with selective carotid angioplasty without developing persistent major neurological complications. All patients except 1 patient subsequently underwent surgery without developing persistent major neurological disabilities. Two patients died of cardiogenic shock within 30 days., Conclusions: Selective carotid angioplasty prior to cardiac surgery in patients with a presumed high risk of stroke was relatively safe and effective in this study group. Although this strategy does not prevent stroke in these high-risk patients, data suggest that this approach shifts the postoperative type of stroke from a severe haemodynamic stroke towards a minor embolic stroke with favourable neurological outcomes. Larger studies are needed to determine whether this strategy can effectively eliminate the occurrence of haemodynamic stroke after cardiac surgery.

Objectives: This study prospectively evaluates the impact of the Haga Braincare Strategy (HBS) on the occurrence of haemodynamic and embolic stroke in a cohort of patients who underwent coronay artery bypass grafting (CABG), valve replacement of a combination of both types of surgery between 2012 and 2015 at the Haga Teaching Hospitals., Methods: The HBS is a dual strategy based on a preoperative vascular work-up of the cerebral circulation by transcranial Doppler and a perioperative monitoring of the cerebral circulation by cerebral oximetry. Duplex of the carotid arteries and/or computed tomography angiography prior to surgery was performed in high-risk patients. Patients with severe carotid artery stenosis were scheduled for carotid angioplasty prior to surgery or waived from surgery., Results: A total of 1065 patients were included. Poor cerebral haemodynamics were identified by transcranial Doppler in 2.1% of patients (n = 22). Based on the HBS, 3 patients were waived from surgery, 4 received preoperative carotid angioplasty followed by cardiac surgery and the remaining patients were operated while being monitored with bilateral cerebral oximetry sensors. In all, 2.2% of the study group experienced a stroke (n = 23), of which none were classified as haemodynamic. Most of the remaining presumed embolic strokes showed a minor to moderate stroke severity., Conclusions: In this single-centre prospective follow-up study, surveillance of cerebral perfusion by the HBS eliminated the occurrence of haemodynamic stroke while most of the residual strokes had a good to favourable prognosis., (© The Author 2017.

For many years, Tourette syndrome (TS) was considered to be a rare disorder, but tics and TS are now recognized as fairly common childhood-onset conditions. Children and adolescents with TS are frequently treated with antipsychotics, either as monotherapy or in combination with psychostimulants, melatonin and selective serotonin reuptake inhibitors (SSRIs). Antipsychotics are most often used in schizophrenia and related psychotic disorders, and in these conditions hyperprolactinemia is one of the most common adverse effects associated with antipsychotics, occurring in 40-50% of patients. We describe two patients with TS who experienced antipsychotic-induced hyperprolactinemia. Treatment options generally consist of dose reduction or switching from typical to atypical antipsychotics. However, diminishing dosages can lead to exacerbations of tics. Also, not all atypical antipsychotics have the same pharmacologic properties required to normalize prolactin levels. The choice of treatment may also be affected by the patient's age and sex. These factors are discussed in relation to these cases, and illustrated by the results of therapeutic interventions over the years., Competing Interests: Conflict of interest statement: The authors declare that there is no conflict of interest.
