A low skull density ratio (SDR) < 0.40 is a known risk factor for treatment failure. The aim of this study was to identify useful sonication strategies for patients with a low SDR < 0.40 by modifying the standard sonication protocol using maximum high-energy sonication while minimizing the number of sonications.</p><p><strong>Methods: </strong>The authors retrospectively analyzed the effects of modified MRgFUS sonication on low-SDR tremor patients. All patients underwent head CT scans to calculate their SDR. The SDR threshold for MRgFUS thalamotomy was 0.35. The patients in the early series underwent the standard sonication protocol targeting the ventral intermediate nucleus contralateral to the treated hand side. The patients with a low SDR < 0.40 in the late series underwent a modified sonication protocol, in which the number of alignment sonications was minimized and high-energy treatment sonication (> 36,000 J) was used. The authors evaluated the lesion volume the following day and tremor improvement and adverse events 3 and 12 months after the procedure. The sonication patterns between low-SDR patients treated using different sonication protocols were examined using Fisher's exact test. ANOVA was used to examine the lesion volume and tremor improvement in high- and low-SDR patients treated using different sonication protocols.</p><p><strong>Results: </strong>Among 41 patients with an SDR < 0.40, 14 underwent standard sonication and 27 underwent modified sonication. Fewer alignment sonications and high-energy treatment sonications were used in the modified sonication group compared with the standard group (p < 0.001). The duration of modified sonication was significantly shorter than that of standard sonication (p < 0.001). The lesion volume and tremor improvement significantly differed among the high- and low-SDR groups with different sonication protocols (p < 0.001). Low-SDR patients treated using modified sonication protocols had comparable lesion volume and tremor improvement to the high-SDR group. The modified sonication protocol did not significantly increase adverse intraprocedural and postprocedural events.</p><p><strong>Conclusions: </strong>Minimizing alignment sonications and applying high-energy sonication in early treatment help to create an optimal lesion volume and control tremor in low-SDR patients.</p>","PeriodicalId":19187,"journal":{"name":"Neurosurgical focus","volume":null,"pages":null},"PeriodicalIF":3.3,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142109992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Likewise, pediatric neurosurgeons do not exclusively offer their services to the young, but they also provide care to adult patients with neurosurgical disorders. This creates a medical system where the transition between specialties is not often a formal and recognized aspect of neurosurgical care because most neurosurgeons provide care for patients of all ages. Additionally, there are very few teams geared toward caring for conditions in children that merit lifelong medical support, with spina bifida (SB) being one of them. Since there are no focused or structured pediatric programs on a large scale, developing a multidisciplinary clinic for adults becomes challenging. A pragmatic approach using technology-based education, supported by an organized system or a coordinator, may be a new strategy. A new system utilizing telemedicine and smartphones for established patients maybe an alternative option for SB children in India. During virtual video conferences, an established patient may benefit from multispecialty care and education toward a smooth transition that avoids significant issues with time, transportation, or financial constraints. Achieving a seamless transition among allied specialists from the pediatric to adult systems is a utopia. The current system in the subcontinent may be improved, with an opportunity to develop smooth transition care between coordinated specialists (who simultaneously treat children and adults).

Lifelong care relationships yield to new care environments that are typically larger, less personal, and less engaged with the nuances of SB care. Adolescence and young adulthood are often characterized by personal and psychological stresses due to factors independent of illness or chronic medical complexity. Surveys have demonstrated that transition is associated with uncertainty, anxiety, and elevated risk of adverse events for many SB patients. To help mitigate this, the authors developed a trial mentorship program between teen patients with SB and undergraduate/medical students. This study analyzes and presents the initial outcomes from this program.</p><p><strong>Methods: </strong>The authors created the Join, Unite, Motivate, and Prepare (JUMP) program to improve readiness for the transition process. The mentee target population was patients aged 13-19 years receiving care at the authors' SB clinic. Mentors were screened/approved undergraduate/medical students who volunteered to participate and successfully completed online training in mentorship. Upon enrollment, each patient set a combination of clinical, self, and parent/guardian goals using the individualized transition plan. These goals were shared with the mentor, mentee, parent/guardian, and physician. To monitor success, the SB program director routinely met with each mentor to discuss progress made and areas of growth. These included continuous quantitative and qualitative goal setting and failures that needed to be addressed for each agenda.</p><p><strong>Results: </strong>Thirteen mentor-mentee matches were created over 9 months. Of the 13 matches, 6 had more than 5 communications after the initial meeting, and 1 mentor-mentee match is still in contact today. Noted success in the program has been through mentees gaining employment, applying for scholarships, starting college, and connecting with others who are going through similar circumstances. Challenges have arisen through failure to follow-up after the initial office visit, risk with using the virtual platform, and wide geographic dispersion of both mentors and mentees across the authors' state.</p><p><strong>Conclusions: </strong>Transition from pediatric to adult care for adolescents with SB has proven to be a large hurdle.
