RESUMO
BACKGROUND: The cross-sectional area (CSA) of the median nerve in Parkinson's disease remains unclear. OBJECTIVES: This meta-analysis assesses median nerve CSA changes in Parkinson's using ultrasonography. METHODS: PubMed, Web of Science, Scopus, and EBSCO were selectively searched for literature on Parkinson's disease, Median nerve, and ultrasonography. Following full-text screening, three studies were included in this meta-analysis with 144 Parkinson's disease patients and 127 controls. The primary outcome was the cross-sectional area of the median nerve; other motor parameters were also evaluated. RESULTS: The cross-sectional area of the median nerve was significantly increased in Parkinson's patients compared to controls (p = 0.007); the standardized mean difference was 0.79 [95% CI (0.21 - 1.37)]. The standardized mean difference of the motor parameters of the median nerve, amplitude, and latency was -0.04 [95% CI (-0.85 to 0.77)] and 0.30 [95% CI (-0.04 to 0.64)], respectively, with statistically insignificant (All p > 0.05). CONCLUSION: This meta-analysis concluded that the cross-sectional area of the median nerve is increased in Parkinson's disease patients. The increase in the CSA of the median nerve might explain the higher prevalence of carpal tunnel syndrome in Parkinson's disease. Further studies are needed to quantify carpal tunnel syndrome prevalence accurately in Parkinson's. LIMITATIONS: Heterogeneity exists due to non-standardized CSA calculation methods and varied disease stages. Finger movement during ultrasound may introduce artifacts, compromising CSA measurement accuracy. Establishing a definitive CSA cut-off for carpal tunnel syndrome in Parkinson's requires further investigation.
RESUMO
INTRODUCTION: The RESCUE-ASDH trial found that disability and quality-of-life outcomes were similar between craniotomy and decompressive craniectomy for traumatic acute subdural hematoma, contrasting previous literature. This meta-analysis aims to validate the applicability of RESCUE-ASDH results using real-world data in acute subdural hematoma patients. METHODS: We searched Chocrane, Embase, and MEDLINE for relevant articles reporting clinical outcomes of craniotomy and decompressive craniectomy. Meta-analysis utilized R software with the restricted maximum likelihood method for random-effects meta-analyses, presenting odds ratios and 95% confidence intervals with Hartung-Knapp-Sidik-Jonkman adjustment for heterogeneity. RESULTS: Besides RESCUE-ASDH, 5 retrospective studies were included, spanning 2006-2016. A total of 961 patients with traumatic ASDH were included in this study (Craniotomy = 467; Decompressive craniotomy = 494). The pooled analysis of retrospective studies showed no significant difference in poor clinical outcomes between the two groups (OR 0.59, 95% CI, 0.32 to 1.10). These findings align with the RESCUE-ASDH trial (OR 0.84, 95% CI, 0.58 to 1.23). Mortality rate was significant higher in patients undergoing craniectomy in pooled result of retrospective studies (OR 0.59, 95% CI, 0.32 to 1.10). In RESCUE-ASDH trial, reoperation rate was higher in the craniotomy group, but the pooled result of retrospective did not show significant difference between the craniotomy and craniectomy group. CONCLUSIONS: This real-world evidence confirms the RESCUE-ASDH trial results. Both craniotomy and decompressive craniectomy yielded similar disability and quality-of-life outcomes for traumatic acute subdural hematoma patients. LEVEL OF EVIDENCE: Level 2, Systematic and meta-analysis.
RESUMO
INTRODUCTION: Once the COVID-19 pandemic was declared, the world was waiting for the clue that would be able to cut down the progression of the disease. Vaccines play a crucial role in reducing the disease and saving many people worldwide. However, there are several side effects of these vaccines, like pain, fatigue, fever, and neurological defects like Bell's palsy. In this systematic review, we presented evidence about the occurrence of Bell's palsy followed by COVID-19 vaccination. METHODS: We searched PubMed, SCOPUS, EBSCO, and Web of Science (WOS) from inception till October 2022. The quality assessment was conducted using the Joanna Briggs Institute, National Institute of Health, and Newcastle-Ottawa. The analysis was conducted on SPSS. RESULTS: Thirty-five records were involved in our study. The results of our cases revealed that most of the patients (62.8%) experienced unilateral facial paralysis. Also, the majority of the cases were reported after the first dose, and most cases were after Pfizer, AstraZeneca, and Sputnik V vaccines, respectively. The patients who were treated with corticosteroids, IVIG, and anti-viral drugs, showed marked recovery afterward. CONCLUSION: The rate ratio of Bell's palsy after COVID-19 vaccination was 25.3 per 1,000,000. The ratio was higher after the first dose compared to the second dose and was higher among those who took Oxford/AstraZeneca vaccine compared to other vaccines. However, this condition was reported in a small number of cases among a large number of vaccinated people worldwide. It is important to note that the benefits of getting vaccinated far outweigh any potential risks.
