Method: An observational type study of 60 subjects between the age group of 60- 94 was carried out, the data analysis was done on the basis of normative values calculated for each age group and we compared heart rate, oxygen saturation and perceived exertion obtained during performance of 2 MST with those obtained during the 6 MWT. Results: According to the age group, normal values of steps were correlated with the two- minutes step test. The more number of steps performed during the twominute step test was associated with higher values of peak oxygen consumption. Comparing 2 MST and 6 MWT in 60 subjects for validity, r=0.935 (P<0.0001). They were statistically equivalent in heart rate (97 ± 4 and 95 ± 4 bpm), oxygen saturation (97 ± 0.5 and 96 ± 0.6%), rating of perceived exertion (13.6 ± 0.4 and 12.4 ± 0.4), and blood pressure (130 ± 4/62 ± 3 and 128 ± 3/62 ± 2 mmHg), (mean ± SE, 2 MST and 6 MWT, respectively). Sensitivity of the 2 MST was high, based both on the number of steps achieved by inpatients (37 ± 13 steps, mean ± SD), and healthy subjects (54 ± 18 steps) (P<0.001), Results suggest that two minute step test has potential as one of the vital tool for aerobic and physical capacity in elderly population which in turn could be a major indicator for the neurological rehabilitation protocols. Conclusion: Although the benefits of two-minutes step test as indicator for aerobic and physical capacity in elderly looks promising, general guidelines for the clinical use of two-minutes step test and its normative values is difficult to make. Future research should explore the normative values for different populations, factors affecting the use of two-minute step test, effects of two-minute step test alone on various systems without in combination with other tests.","PeriodicalId":91329,"journal":{"name":"Journal of neurology and neuroscience","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69700779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Separating Parkinson’s disease related pain from pain of other origin is very difficult. They all come under one umbrella among the different forms of Parkinson’s disease related pain, musculoskeletal pain is the most common form accounting for 40% in PD. Pain occurs in about 60% of Parkinson’s disease patients, two to three times more frequent in this population than in age matched healthy individuals. It is an early and potentially disabling symptom that can precede motor symptoms by several years. The lower back and lower extremities are the most commonly affected areas. The most used classification for pain in PD defines musculoskeletal, dystonic, central, or neuropathic/radicular forms. Its different clinical characteristics, variable relationship with motor symptoms and inconsistent response to dopaminergic drugs suggest that the mechanism underlying pain in Parkinson’s disease is complex and multifaceted, involving the peripheral nervous system, generation and amplification of pain by motor symptoms and neuro-degeneration of areas related to pain. The basal ganglion processes somatosensory information differently. Increased subjective pain sensitivity with lower electrical and heat pain threshold has been reported in Parkinson’s disease patients. The mechanism is assumed to be diminished activity of the descending inhibitory system of the basal ganglia. Promising perspectives for this have come from studies using different pain scales in Parkinson’s disease. Selection criteria- “King’s Parkinson’s disease pain scale,” which was proposed by a multicenter group that included King’s College Hospital in London, is officially advocated by the “International Parkinson’s and Movement Disorder Society Non-Motor PD Study Group” for evaluating pain in Parkinson’s disease treatment prevalence.","PeriodicalId":91329,"journal":{"name":"Journal of neurology and neuroscience","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69700432","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We aimed to investigate the rate and characteristics of stroke mimics (SM) and missed strokes (MS). Research Methodology: We used data of consecutive “suspected stroke” admissions in a tertiary academic Hospital from January 2016 to July 2018. Diagnosis of SM was based on the absence of an ischaemic infarct on neuroimaging plus the presence an alternate discharge diagnosis. MS were defined as any patient with a discharge diagnosis of stroke whose stroke-like symptoms were missed in the Emergency Department (ED). Findings: Of 1745 patients reviewed, 63% were ischaemic stroke, 18% Intra-Cranial Haemorrhage (ICH), and 18% SM. We detected 95 MS. Stroke risk factors were significantly less common among SM and MS compared to stroke patients. Younger age, female gender, dizziness, ataxia, absence of limb weakness, and absence of certain vascular risk factors were predictors of SM. For MS, the predicting factors were young age (<55), confusion at presentation, hypercholesterolemia, and absence of hypertension. Conclusion: Atypical presenting symptoms can cause over and under-diagnosis of stroke. MS and SM are similar in many aspects. These diagnostic errors occur more often in younger patients with less severe neurological symptoms and symptoms attributable to posterior circulation.","PeriodicalId":91329,"journal":{"name":"Journal of neurology and neuroscience","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69698988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, studies conducted in recent years indicate that elevated serum UA levels are an independent risk factor for stroke. The aim of our study is to determine the relationship between UA and acute ischemic stroke and subtypes. Methods: We retrospectively analyzed 110 patients with acute ischemic stroke within the first 24 hours who were admitted to Bakirkoy Prof Dr. Mazhar Osman, Mental and Neurological Diseases Training and Research Hospital (Istanbul, Turkey) between August 2016 and August 2017. The control group was composed of 82 healthy volunteers who were compatible with the patient group in terms of age and gender. Serum UA levels were estimated and stroke subtypes were determined by Bamford classification according to clinical findings and TOAST classification according to etiology. Results: Mean serum UA levels were found 5,5 mg/dL in the patient group versus 4,8 mg/dL in the control group. There was a statistically significant difference between patients and controls (p<0,0019). As for the stroke subtypes, elevated serum UA was found to be associated with all stroke subtypes except lacunar stroke according to Bamford classification and small vessel disease according to TOAST classification. In Multiple Logistic Regression Analysis, serum UA levels higher than 5,6 mg/dL were identified as independent risk factors for ischemic stroke. Conclusion: In our study, high UA levels were seen as an independent risk factor for stroke. Determination of UA as an etiological factor responsible for the pathogenesis of vascular diseases including stroke may also bring the treatment of hyperuricemia such as hyperlipidemia or hypertension, which are routinely treated after stroke.","PeriodicalId":91329,"journal":{"name":"Journal of neurology and neuroscience","volume":"31 4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69699156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Benign paroxysmal positional vertigo (BPPV), vestibular migraine (VM) and posterior circulation ischemia (PCI) are the three common causes of vertigo, all of which are related to abnormal calcium function. As a calcium antagonist, flunarizine has a multitude of mechanisms of action in vertigo treatment. The drug exerts neuroprotective effects on brain, endothelial and hair cells of the inner ear; reduces angiospasm, normalizes blood viscosity, improves the circulation of blood flow to the brain and inner ear; protects and restores injured neuronal or vascular cells from hypoxic-ischaemic damage; accelerates vestibular function recovery and inhibits cortical spreading depression (CSD). Many studies showed flunarizine to be effective especially against vertiginous attacks resulting from BPPV, VM and PCI with few serious side effects, probably due to its multiple mechanisms of action.","PeriodicalId":91329,"journal":{"name":"Journal of neurology and neuroscience","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69699338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, the association between hyperoxia and outcomes in patients with TBI remains debatable. We assessed the effect of hyperoxia on the neurological outcomes and survival of critically ill patients with moderate-severe TBI. Methods: This was a retrospective cohort study of all adults with moderatesevere TBI admitted to the ICU between 1st January 2016 and 31st December 2019 who required invasive mechanical ventilation. We noted ABGs performed with the first 3 hours of intubation, then 6-12 hours and 24-48 hours. The patients were divided into two categories: normoxia (PaO2 60-99 mmHg) and hyeroxia (PaO2 >100 mmHg). Multivariable logistic regression was performed to assess predictors of hospital mortality and good neurologic outcome (Glasgow outcome score [GOS] ≥ 4). In a second analysis the patients were divided into survivors and non-survivors. Results: The study included 308 patients: 23.4% (n=72) in normoxia group and 76.6% (n=236) in hyeroxia group. Hyperoxia was not associated with increased hospital (43% vs. 18%, p=0.20) mortality. Further, the hospital discharge GCS (10 ± 5 vs. 11 ± 4, p=0.10) and GOS (3 ± 1 vs. 3 ± 1, p=0.35) were similar. In multivariable logistic regression analysis, hyperoxia was not associated with increased mortality (adjusted odds ratio [aOR] 0.99, 95% CI 0.99-1.00, p=0.11). PaO2 within different ranges was also not associated with mortality: 100-200 mmHg: aOR 0.60, 95% CI 0.29-1.52; 201-300 mmHg: aOR 0.66, 95% CI 0.29-1.52; 301-400 mmHg: aOR 0.80, 95% CI 0.31-2.09; and >400 mmHg: aOR 0.39, 95% CI 0.14-1.08; reference: PaO2 60-99 mmHg. The Kaplan-Meier survival curve for normoxia verses hyperoxia showed no significant difference for all-cause mortality. In the survivors verse nonsurvivors analysis, the PaO2 were (median, IQT) 199 mmHg (111-329) and 165 mmHg (84-252), respectively. Conclusion: Hyperoxia (PaO2 >100 mmHg) was not associated with increased mortality or poor neurological outcomes (determined by GOS) in moderatesevere TBI patients.","PeriodicalId":91329,"journal":{"name":"Journal of neurology and neuroscience","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69700078","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, due to the neurophysiology of the bioelectrical signal and the short duration of the routine EEG (rEEG) and sleepdeprived EEG (sEEG) registers, the sensitivity is low. The 24-hour Ambulatory EEG (aEEG), being a prolonged recording, could significantly improve the diagnostic capability, in an attractive cost-effective way. In this study, we analyzed the aEEG of patients with suspected epilepsy, addressing its specificity and sensitivity for the clinical diagnosis of epilepsy. Additionally, we endeavour to ascertain any other possible predictive factors of diagnosis. Methods and Findings: Retrospective observational study enrolling consecutive patients with suspected epilepsy who underwent aEEG between May 2011 and May 2018 at the Neurophysiology Laboratory from Local Health Unit of Matosinhos – Pedro Hispano Hospital. A sample of 83 individuals was obtained, with a mean age of 44.5 years (79 adults and 4 paediatric). aEEG showed a good diagnostic capacity for the clinical diagnosis of epilepsy with a specificity of 97% and sensitivity of 68%. The rate of false-negatives and false-positives was 7% and 5%, respectively. It’s expected that patients with an indication of syncope or loss of consciousness will not have epilepsy diagnosis. Conclusion: The aEEG can be a useful tool to assess patients with suspected epilepsy and unremarkable routine and sleep-deprived EEGs, or in cases of suspected non-epileptic seizures, particularly to exclude the epilepsy diagnosis given its high specificity. This approach can lessen the time required to identify the diagnosis.","PeriodicalId":91329,"journal":{"name":"Journal of neurology and neuroscience","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69699145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Evidence exists that (i) ALR is variously expressed by many neurons in the central nervous system; (ii) ALR is differently expressed in female and male cells; (iii) neurodegenerative diseases triggered by dysregulation of cell normoxic conditions differently affect the 2 sexes. Aim: Aim of the present study was to analyze the ALR presence in the prosencephalon of female and male mice and evaluate whether differences in expression exist between the two genders. Methods: Harvested prosencephala were investigated by Western blotting and immunohistochemistry to assess ALR expression. Results: Western blotting revealed 2 ALR isoforms, ALR-21 and ALR-23, both more expressed in male prosencephalon. Immunohistochemistry revealed ALRimmunoreactive neurons diffusely distributed in the prosencephalon, but with a significantly higher number in male prosencephalon. Conclusion: The different ALR expression level in female and male mouse prosencephalon may represent a marker of sexual dimorphism. The higher ALR expression seen in male prosencephalic neurons suggests that ALR, an antioxidant factor, could parallel the antioxidant effect of female sex steroid hormones that are known to be more effective compared to the male sexual steroids in protecting against the oxidative stress. These data open new options to study the neurodegenerative diseases, particularly those showing gender differences in terms of epidemiology.","PeriodicalId":91329,"journal":{"name":"Journal of neurology and neuroscience","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69699716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
