Previous treatments to the local inflammation occurring in the facial nerve as it exits the stylomastoid foramen with ultrasound, non-stimulating electrical currents and electrical functional muscle stimulation of the compromised facial muscles, often do not restore full function to the affected side of the face. A non-interventional pulsed radio frequency (NI-PRF) electrical current has been observed to stimulate the facial nerve with fasciculations occurring in the main branch of the VII th nerve and its concomitant branches to the upper, middle and lower areas of the face resulting in improved motor function. This commences immediately within the first treatment in acute Bell’s Palsy and only 4-6 treatments are required to assist most patients. Prolonged conditions that were previously thought unrecoverable (after years) have restored motor control and this usually occurs between 1 – 3 months of treatment. Treatment requisite does not have to be continuous and can be given twice weekly or even once weekly over the period mentioned above. Even if treatment is interrupted the condition continues to improve. This would have both an economic and efficient time saving impact on these patients.

It commonly affects patients over 50 years, and occurs more frequently in women. Treatment options include medical therapy, surgery (microvascular decompression (MVD) and percutaneous balloon compression (PBC)) and Gamma Knife® radiosurgery (GKRS). GKRS has been available at the Princess Alexandra Hospital since October 2015. Our objective was to evaluate the efficacy of GKRS on patients with TN and investigate the impact of known prognostic variables on patient outcomes. Method: A retrospective review was conducted on all patients who received GKRS for TN from October 2015 till March 2018 in a single center tertiary neurosurgical referral hospital. Results: 43 patients with TN were treated with GKRS with a median follow up time after treatment of 7 months (6 weeks - 36 months). Median age was 69 years, 51% were female and 21% had atypical symptoms. 33% previously had surgery (7=MVD, 7=PBC). Clinical benefit after GKRS was observed in 79% of patients at 1 month, 73% at 3 months, 74% at 6 months and 87% at 1 year. Of the 49% who experienced a relapse of pain within 1 year post GKRS, the median time to relapse was 8 weeks. No serious adverse events or severe toxicity were recorded. Patient and treatment factors that predicted worse outcomes were the presence of a vessel contacting the nerve, female gender and a higher radiation dose. Conclusion: GKRS is an effective treatment option for patients with TN and it is particularly useful to consider in those with co-morbidities that make surgery high risk. GKRS has acceptable short-term beneficial results in TN, however with relapse other treatment options may be required.","PeriodicalId":21130,"journal":{"name":"Restorative neurology and neuroscience","volume":"18 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2021-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80491344","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Children are expected to be prepared for this and to receive a tablet or cell phone as early as possible. This, however, poses a huge risk because a child’s brain must initially organize itself in an analog fashion. This means that the spatial-modular building of neural networks and the rhythmic timing of brain activities mature very slowly through upbringing and school education to support memory formation and thinking. Once this foundation has been established, a digital workplace will be easily accessible to any young adult. To investigate in more detail the impacts of private cell phone use on the learning abilities of children, we designed a cognitive test that, among other things, measures spatiotemporal abilities and memory performance. A total of 54 third-grade students (aged 8 and 9) were subjected to the testing at an elementary school in the Rhein-Neckar-Kreis/Baden Württemberg region from December 2019 to March 2020. The intensity of private cell phone use was measured with a nonverbal method, the evidence-based water glass method. Prior to testing, we evaluated the children’s ability to evaluate themselves with this nonverbal method and designed a lie item, which allowed us to filter out those children who were unable to evaluate themselves. Due to the high data quality, variance analysis was used to analyze the quantified data statistically. The results showed that prefrontal cortex skills such as spatial perception, concentration, and anticipation were significantly poorer in third-graders with heavy cell phone use compared to those with little or no cell phone use. The heavier the cell phone use, the less well developed was their cognitive memory performance if it included a time delay. Furthermore, we observed a significant impact of the intensity of cell phone use on the motivation to go to school. The frequency of sports activities, playing outdoors, friendships, and homework was not significantly affected by cell phone use. The reason for this could be that modern schoolchildren only have rather limited control over the timing of these activities. Overall, the data suggest that other cognitive and emotional-motivational abilities such as spelling and handwriting are also adversely affected by heavy cell phone use. This could be verified by an investigation with a larger sample size. The findings of this pilot study should be a warning: with the digital transformation, our society could cause severe and also irreversible cognitive damage to the young generation.
