RESUMO

PURPOSE: Cervicothoracic ventral-dorsal rhizotomy (VDR) is a potential treatment of medically refractory hypertonia in patients who are not candidates for intrathecal baclofen, particularly in cases of severe upper limb hypertonia with limited to no function. A longitudinal cohort was identified to highlight our institutional safety and efficacy using cervicothoracic VDR for the treatment of hypertonia. METHODS: Retrospective data analysis was performed for patients that underwent non-selective cervicothoracic VDR between 2022 and 2023. Non-modifiable risk factors, clinical variables, and operative characteristics were collected. RESULTS: Six patients (three female) were included. Four patients underwent a bilateral C6-T1 VDR, one patient underwent a left C7-T1 VDR, and another underwent a left C6-T1 VDR. Three patients had quadriplegic mixed hypertonia, one patient had quadriplegic spasticity, one patient had triplegic mixed hypertonia, and one patient had mixed hemiplegic hypertonia. The mean difference of proximal upper extremity modified Ashworth scale (mAS) was - 1.4 ± 0.55 (p = 0.002), and - 2.2 ± 0.45 (p < 0.001) for the distal upper extremity. Both patients with independence noted quality of life improvements as well as increased ease with dressing and orthotics fits. Caregivers for the remaining four patients noted improvements in caregiving provision, mainly in dressing, orthotics fit, and ease when transferring. CONCLUSION: Cervicothoracic VDR is safe and provides tone control and quality of life improvements in short-term follow-up. It can be considered for the treatment of refractory hypertonia. Larger multicenter studies with longer follow-up are necessary to further determine safety along with long-term functional benefits in these patients.

RESUMO

OBJECTIVE: Children with cerebral palsy (CP) often experience medically refractory hypertonia, for which there are surgical therapies including neuromodulation and rhizotomy. Traditional surgical treatment for medically refractory mixed hypertonia or dystonia includes intrathecal baclofen pumps and selective dorsal rhizotomy. A nonselective lumbosacral ventral-dorsal rhizotomy (VDR; ventral and dorsal roots lesioned by 80%-90%) has the potential to address the limitations of traditional surgical options. The authors highlighted the institutional safety and efficacy of nonselective lumbosacral VDR for palliative tone management in nonambulatory patients with more severe CP. METHODS: The authors performed a retrospective analysis of patients who had undergone lumbosacral VDR between 2022 and 2023. Demographic factors, clinical variables, and operative characteristics were collected. The primary outcomes of interest included tone control and quality of life improvement. Secondary outcome measures included, as a measure of safety, perioperative events such as paresthesias. Postoperative complications were also noted. RESULTS: Fourteen patients (7 female) were included in the study. All patients had undergone a T12-L2 osteoplastic laminoplasty and bilateral L1-S1 VDR. Nine patients had quadriplegic mixed hypertonia, 4 had quadriplegic spasticity, and 1 had generalized secondary dystonia. Following VDR, there was a significant decrease in both lower-extremity modified Ashworth Scale (mAS) scores (mean difference [MD] -2.77 ± 1.0, p < 0.001) and upper-extremity mAS scores (MD -0.71 ± 0.76, p = 0.02), with an average follow-up of 3 months. In the patient with generalized dystonia, the lower-extremity Barry-Albright Dystonia Scale score decreased from 8 to 0, and the overall score decreased from 32 to 13. All parents noted increased ease in caregiving, particularly in terms of positioning, transfers, and changing. The mean daily enteral baclofen dose decreased from 47 mg preoperatively to 24.5 mg postoperatively (p < 0.001). Three patients developed wound dehiscence, 2 of whom had concurrent infections. CONCLUSIONS: Lumbosacral VDR is safe, is effective for tone control, and can provide quality of life improvements in patients with medically refractory lower-limb mixed hypertonia. Lumbosacral VDR can be considered for palliative tone control in nonambulatory patients with more severe CP. Larger studies with longer follow-ups are necessary to further determine safety and long-term benefits in these patients.

RESUMO

OBJECTIVE: Intrathecal baclofen (ITB) is an effective treatment for hypertonia in children involving the implantation of a pump and catheter system. The highest concentration of ITB is at the catheter tip. The catheter tip location is most commonly within the lumbar or thoracic spine. The cervical tip location has traditionally been avoided because of concerns of hypoventilation and pneumonia; however, these complications in cervical compared with thoracic or lumbar placement have not been reliably proven. Some studies have suggested that cervical ITB location better treats upper-extremity hypertonia. There are limited data describing the safety and efficacy of cervical ITB on hypertonia. The authors present a single-institution retrospective case series highlighting the safety and efficacy of using cervical ITB location for the treatment of hypertonia. METHODS: Retrospective data analysis was performed for children who underwent continuous dosing cervical ITB between April 2022 and October 2023. Nonmodifiable risk factors, clinical variables, operative characteristics, and adverse outcomes were collected. RESULTS: This study included 25 patients (8 female). The mean age at implantation was 12.4 years, and the mean operative duration was 90 minutes. The mean Barry-Albright Dystonia Scale score decreased by 9.5 points (p = 0.01). The mean aggregated modified Ashworth scale score in the upper extremities decreased by 2.14 points (p = 0.04), and that in the lower extremities decreased by 4.98 points (p < 0.01). One patient each (4%) had infection and baclofen toxicity. Two patients (8%) had respiratory depression requiring continuous positive airway pressure. There was no incidence of pneumonia or wound dehiscence. CONCLUSIONS: The cervical catheter tip location for ITB is safe, is effective to control tone, and should be considered for the treatment of hypertonia. Larger studies with longer follow-up are necessary to further determine upper-limit dosing safety along with long-term functional benefits in these patients.

RESUMO

OBJECTIVE: Intrathecal baclofen (ITB) is an effective treatment for refractory hypertonia in children. ITB has long been effective for the treatment of spasticity, and indications have naturally evolved to include dystonia and mixed pediatric movement disorders (PMDs). The established uses for ITB trials are insurance prerequisite, mixed tone, and family request. Despite agreement for ITB therapy by a multidisciplinary group of subspecialists in a complex PMD program, insurance companies often require an ITB trial be performed. A longitudinal cohort was identified to determine the safety and efficacy of ITB trials and to determine the utility of test dosing in this population. METHODS: Retrospective data analysis was performed for patients with hypertonia who underwent ITB bolus trials at the authors' institution between 2021 and 2023. Nonmodifiable risk factors and clinical variables were collected. RESULTS: Thirty-one patients (11 female) underwent 32 ITB trials. Of these patients, 67.7% had a diagnosis of mixed hypertonia, 32.3% pure spasticity, and 9.1% secondary dystonia. The mean age at test dose was 12.8 years, and 58.1% of patients were born premature. The mode Gross Motor Function Classification System score was 5. The mean difference in Barry-Albright Dystonia Scale (BADS) scores was -7.33 points (p = 0.01) at 2.5 hours postoperatively. The mean difference in upper-extremity modified Ashworth Scale (mAS) scores was -5.36 points (p = 0.003), and that for lower-extremity mAS scores was -6.61 (p < 0.001). In total, 21.9% of patients developed a post-dural puncture headache. Conversion to a permanent baclofen pump was performed in 22/32 (68.8%) patients. Of those who did not pursue pump placement, 1 patient had high surgical risk, 1 had an ineffective response, 1 had a bad reaction to the test dose and cited both regression and increased discomfort, and 2 declined despite an effective trial owing to family preferences. CONCLUSIONS: ITB trials require hospitalization in some form and carry risks of procedural complications. The decision to pursue a trial should be made on a case-by-case basis by clinicians and should not be determined by insurance companies. The complication rate of ITB trials is high, and a test dose is unnecessary in this fragile population.

RESUMO

OBJECTIVE: Twitter (X) is increasingly utilized by medical residency programs to boost engagement and potentially enhance ranking. This study aims to evaluate the role of Twitter (X) in neurosurgery residency programs, assessing their online activity, followership, and content to identify current practices and potential improvements. METHODS: We identified 97/123 neurosurgery residency programs in the United States with Twitter accounts. Active accounts, posting in 2022 and 2023, were matched with the American Association of Neurological Surgeons Neurosurgical Residency Training Program Directory. Tweets from January 2022 through June 2023 were categorized as original or retweets and further subcategorized based on content. Descriptive and correlation analyses were conducted. RESULTS: Twitter (X) accounts were found for 78.8% of accredited neurosurgery programs (n = 97/123), with 68.3% active as of July 2023 (n = 84/123). All active accounts amassed 167,068 followers. Among 5612 tweets identified, 2764 were original content, and 2848 were retweets. Tweets primarily focused on resident or program information (64.3%), research publications (32.0%), and conference participation (9.4%). Only 12.3% (n = 341) of original tweets contained public medical information. A significant correlation (r = 0.493, P < 0.001) was observed between Twitter (X) following and program ranking. CONCLUSIONS: The majority of US neurosurgery residency programs actively use Twitter (X), primarily to showcase academic achievements and aid in recruitment. The correlation between Twitter following and program ranking suggests that online engagement reflects program visibility and impact, underscoring the importance of social media in program outreach and strategic management for maximizing program benefits.

RESUMO

BACKGROUND: The path through neurosurgery is rigorous. Many neurosurgeons may experience burnout, depression, or suicide throughout training and practice. We review the literature to help foster a culture of awareness and self-care and arm trainees with coping skills to reduce burnout and, thus, suicidality during all phases of their medical careers. METHODS: A systematic search was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines using 4 databases. 7 studies were included. RESULTS: Overlying themes of interventions were to increase balance, mindfulness, and physical fitness. The most common interventions included in programs were educational and physical activity. We suggest a comprehensive wellness program emphasizing interventions from 4 wellness dimensions-physical, spiritual, mental, and emotional. CONCLUSIONS: Many neurosurgeons experience burnout, leading to a lack of satisfaction and early retirement; this necessitates a discipline-wide acknowledgment of endemic burnout among neurosurgeons. Systemic changes are needed to refine the training process and prioritize physician well-being- this cannot be left to chance.

RESUMO

BACKGROUND AND OBJECTIVES: The most common treatment of hydrocephalus is ventriculoperitoneal (VP) shunting. Peritoneal access is commonly conducted through an open laparotomy, but laparoscopic peritoneal access is gaining popularity. Many studies have reported the benefits of minimally invasive laparoscopic peritoneal access, but there is no consensus on its use. We conducted a systematic review and meta-analysis to compare open laparotomy vs laparoscopic peritoneal access in VP shunting. METHODS: A systematic search was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines using 3 databases. Twelve studies included only adults, 3 included only pediatric patients, and 3 included both adults and pediatric patients. RESULTS: Compared with open laparotomy, laparoscopic peritoneal access was associated with a reduction in distal shunt failure (6.1% vs 2.2%, P = .01), operative time (69.4 vs 56.3 minutes, P < .001), and length of stay (LOS) (9.6 vs 7.3 days, P < .001). There were no differences in proximal shunt failure, total shunt failure, intraoperative complications, or infection rate. In the pediatric population, laparoscopic access was associated with a reduced LOS (7.8 vs 5.9 days, P < .001). Heterogeneity was high but explained by the varying study populations and techniques. CONCLUSION: Laparoscopic peritoneal access for VP shunt insertion is associated with improved outcomes, including reduced distal shunt failure, reduced operative time, and reduced hospital LOS, when compared with open laparotomy and should be considered for shunt insertion. Additional studies are necessary to further determine the benefit of laparoscopic access, especially in the pediatric population.

RESUMO

BACKGROUND: Management of medically refractory limb-specific hypertonia is challenging. Neurosurgical options include deep brain stimulation, intrathecal baclofen, thalamotomy, pallidotomy, or rhizotomy. Cervical dorsal rhizotomy has been successful in the treatment of upper-extremity spasticity. Cervical ventral and cervical ventral-dorsal rhizotomy (VDR) has been used in the treatment or torticollis and traumatic hypertonia; however, the use of cervicothoracic VDR for the treatment of upper-extremity mixed hypertonia is not well described. OBSERVATIONS: A 9-year-old girl with severe quadriplegic mixed hypertonia secondary to cerebral palsy (CP) underwent cervicothoracic VDR. Modified Ashworth Scale scores, provision of caregiving, and examination improved. Treatment was well tolerated. LESSONS: Cervicothoracic VDR can afford symptomatic and quality of life improvement in patients with medically refractory limb hypertonia. Intraoperative positioning and nuances in surgical techniques are particularly important based on spinal cord position as modified by scoliosis. Here, the first successful use of cervicothoracic VDR for the treatment of medically refractory upper-limb hypertonia in a pediatric patient with CP is described.

RESUMO

BACKGROUND: Cerebral vasospasm is commonly associated with adult aneurysmal subarachnoid hemorrhage but can develop in children. The standard vasospasm treatment includes induced hypertension, avoidance of hypovolemia, systemic use of the calcium channel blocker (CCB) nimodipine, and cerebral angiography for intraarterial therapy. Emerging treatments in adults, such as intraventricular CCB administration, have not been investigated in children. This study demonstrates the successful use of an intraventricular CCB in a pediatric patient with refractory vasospasm secondary to meningitis. OBSERVATIONS: A 12-year-old female presented with Streptococcus pneumoniae meningitis and ventriculitis with refractory symptomatic cerebral vasospasm. She received a 5-day course of intrathecal nicardipine through an existing external ventricular drain. Her clinical status, transcranial Doppler studies, and radiography improved. Treatment was well tolerated. LESSONS: Pediatric vasospasm is uncommon and potentially devastating. The management of vasospasm in adults occurs frequently. Principles of this management are adapted to pediatric care given the rarity of vasospasm in children. The use of intraventricular nicardipine has been reported in the care of adults with level 3 evidence. It has not been adequately reported in children with refractory vasospasm. Here, the first use of intraventricular nicardipine in treating pediatric cerebral vasospasm in the setting of meningitis is described and highlighted.

RESUMO

BACKGROUND: Children with cerebral palsy often have neurogenic bladders. Bladder function is further affected by complex medical management and multifactorial disease processes, leading to worsened function and poorer quality of life. Intrathecal baclofen (ITB) therapy has been used to treat hypertonia and spasticity, but implications in neurogenic bladder management have not been well described. OBSERVATIONS: A 20-year-old female with a history of cerebral palsy and neurogenic bladder treated with sacral neuromodulation underwent ITB therapy and subsequently experienced improvement in bladder control, obviating the need for bladder stimulator use. LESSONS: ITB improves hypertonia and can effectively obviate the need for neurostimulation to treat neurogenic bladder in patients with cerebral palsy. Further research is necessary to discern mechanisms. https://thejns.org/doi/10.3171/CASE24364.

RESUMO

BACKGROUND: Implantable devices are increasingly more common for management of movement disorders, pain, and epilepsy. These devices are often complex and constructed of nonbiodegradable or hazardous materials. Therefore, proper postmortem handling of these devices is exceedingly important. Unfortunately, there is no consolidated resource available for postmortem neuromodulation device protocols. Thus, we surveyed and catalogued the protocols for implantable devices to summarize proper postmortem device protocols for implantable neurosurgical devices currently on the market. METHODS: We performed a cross-sectional study of companies producing commonly implanted neurosurgical devices. Using information from company websites, user manuals, and catalogs we categorized devices into 3 groups: A (formal recommendation for explantation), B (recommendation for explantation without formal company protocol), and C (explantation is not necessary). We then compiled the data into a stoplight diagram, providing a clear postmortem disposal algorithm for each device category. RESULTS: Twelve companies were queried regarding 46 devices. Postmortem protocols were available for 50% (23/46) of devices; the remaining devices did not have formal recommendations. Overall, 50% of devices were classified as category A "red light" on the stoplight diagram based on recommendations, 10.9% as category B "yellow light," and the remaining 39.1% were classified as category C "green light" indicating they are safe to bury or cremate. CONCLUSIONS: Evolution in therapies and growth in functional neurosurgery has expanded the range of implantable neurosurgical devices. We provide an educational document summarizing their postmortem protocols. This resource aims to aid health-care providers and encourage proper disposal practices during burial or cremation.

RESUMO

OBJECTIVE: Diffuse intrinsic pontine gliomas (DIPGs) are aggressive and malignant tumors of the brainstem. Stereotactic biopsy can obtain molecular and genetic information for diagnostic and potentially therapeutic purposes. However, there is no consensus on the safety of biopsy or effect on survival. The authors aimed to characterize neurological risk associated with and the effect of stereotactic biopsy on survival among patients with DIPGs. METHODS: A systematic review was performed in accordance with PRISMA guidelines to identify all studies examining pediatric patients with DIPG who underwent stereotactic biopsy. The search strategy was deployed in PubMed, Embase, and Scopus. The quality of studies was assessed using the Grading of Recommendations, Assessment, Development and Evaluation system, and risk of bias was evaluated with the Cochrane Risk of Bias in Nonrandomized Studies-of Interventions tool. Bibliographic, demographic, clinical, and outcome data were extracted from studies meeting inclusion criteria. RESULTS: Of 2634 resultant articles, 13 were included, representing 192 patients undergoing biopsy. The weighted mean age at diagnosis was 7.5 years (range 0.5-17 years). There was an overall neurosurgical complication rate of 13.02% (25/192). The most common neurosurgical complication was cranial nerve palsy (4.2%, 8/192), of which cranial nerve VII was the most common (37.5%, 3/8). The second most common complication was perioperative hemorrhage (3.6%, 7/192), followed by hemiparesis (2.1%, 4/192), speech disorders (1.6%, 3/192) such as dysarthria and dysphasia, and movement disorders (1.0%, 2/192). Hydrocephalus was less commonly reported (0.5%, 1/192), and there were no complications relating to wound infection/dehiscence (0%, 0/192) or CSF leak (0%, 0/192). No mortality was specifically attributed to biopsy. Diagnostic yield of biopsy revealed a weighted mean of 97.4% (range 91%-100%). Of the studies reporting survival data, 37.6% (32/85) of patients died within the study follow-up period (range 2 weeks-48 months). The mean overall survival in patients undergoing biopsy was 9.73 months (SD 0.68, median 10 months, range 6-13 months). CONCLUSIONS: Children with DIPGs undergoing biopsy have mild to moderate rates of neurosurgical complications and no excessive morbidity. With reasonably acceptable surgical risk and high diagnostic yield, stereotactic biopsy of DIPGs can allow for characterization of patient-specific molecular and genetic features that may influence prognosis and the development of future therapeutic strategies.

RESUMO

Impaired emotional processing and cognitive functioning are common in schizophrenia, schizoaffective disorder, and bipolar disorders, causing significant socioemotional disability. While a large body of research demonstrates abnormal cognition/emotion interactions in these disorders, previous studies investigating abnormalities in the emotional scene response using event-related potentials (ERPs) have yielded mixed findings, and few studies compare findings across psychiatric diagnoses. The current study investigates the effects of emotion and repetition on ERPs in a large, well-characterized sample of participants with schizophrenia-bipolar syndromes. Two ERP components that are modulated by emotional content and scene repetition, the early posterior negativity (EPN) and late positive potential (LPP), were recorded in healthy controls and participants with schizophrenia, schizoaffective disorder, bipolar disorder with psychosis, and bipolar disorder without psychosis. Effects of emotion and repetition were compared across groups. Results displayed significant but small effects in schizophrenia and schizoaffective disorder, with diminished EPN amplitudes to neutral and novel scenes, reduced LPP amplitudes to emotional scenes, and attenuated effects of scene repetition. Despite significant findings, small effect sizes indicate that emotional scene processing is predominantly intact in these disorders. Multivariate analyses indicate that these mild ERP abnormalities are related to cognition, psychosocial functioning, and psychosis severity. This relationship suggests that impaired cognition, rather than diagnosis or mood disturbance, may underlie disrupted neural scene processing in schizophrenia-bipolar syndromes.
