Abstract Background Increasing use of deep brain stimulation (DBS) over the past 20 years is paralleled by a rise in DBS infections. There is a paucity of data on the diagnosis, management, and outcomes in such infections. We describe our center’s experience with DBS infections. Methods Adults ( >18 years) diagnosed with DBS associated infection between January 1, 2000 and May 1, 2020 were retrospectively reviewed. Data on patient demographics, clinical presentation, microbiology, and management was collected. Results Seventy cases were identified (table 1). The mean age at diagnosis was 58.9 ± 16.5 years. The bulk were free of comorbidities. Parkinson’s disease and essential tremors were the most common indications for DBS placement. The median time from implantation to infection was 4 months [IQR 1,24]. The neurotransmitter and extension wires were the most frequently infected parts. A microbiological diagnosis was made in 89% of cases, 47% of which were polymicrobial. The most commonly identified organisms were Staphylococcus aureus, Cutibacterium acnes, and coagulase-negative staphylococci. For patients with deep infection, 71% had complete device extraction, 20% partial extraction, and 9% device retention; clinical cure at 3 months occurred in 97%, 64% and 100%, respectively (figure 1). On the other hand, 93% of patients with superficial infection had device retention; cure at 3 months was seen in 64% (figure 2). Suppressive oral antibiotics were rarely used, 45% of patients with partial extraction and 26% with device retention. DBS was reimplanted in 71% of patients after complete extraction and led to reinfection in 30% at 1 year follow up. Median time to reimplantation was 2.7 months. All patients who failed at 3 months in the partial extraction and device retention cohorts subsequently underwent complete device removal leading to clinical cure sustained at 1 year follow up. Conclusion All patients who had complete extraction achieved clinical cure at 3-months follow-up, while high failure rates occurred in those with device retention. Most infections were polymicrobial and predominantly caused by gram-positive pathogens. Thirty percent of patients with re-implantation after complete device extraction developed re-infection within 1 year. Disclosures All Authors: No reported disclosures

Abstract BACKGROUND: Deep brain stimulation (DBS) at the internal globus pallidus (GPi) has replaced ablative procedures for the treatment of primary generalized dystonia (PGD) because it is adjustable, reversible, and yields robust clinical improvement that appears to be long lasting. OBJECTIVE: To describe the long-term responses to pallidal DBS of a consecutive series of 22 pediatric patients with PGD. METHODS: Retrospective chart review of 22 consecutive PGD patients, ≤21 years of age treated by one DBS team over an 8-year period. The Burke-Fahn-Marsden Dystonia Rating Scale (BFMDRS) was used to evaluate symptom severity and functional disability, pre- and post-operatively. Adverse events and medication changes were also noted. RESULTS: The median follow-up was 2 years (range, 1-8 years). All 22 patients reached 1-year follow-up; 14 reached 2 years, and 11 reached 3 years. The BFMDRS motor subscores were improved 84%, 93%, and 94% (median) at these time points. These motor responses were matched by equivalent improvements in function, and the response to DBS resulted in significant reductions in oral and intrathecal medication requirements after 12 and 24 months of stimulation. There were no hemorrhages or neurological complications related to surgery and no adverse effects from stimulation. Significant hardware-related complications were noted, in particular, infection (14%), which delayed clinical improvement. CONCLUSION: Pallidal DBS is a safe and effective treatment for PGD in patients <21 years of age. The improvement appears durable. Improvement in device design should reduce hardware-related complications over time.

Pain from Parkinson's disease (PD) is a non-motor symptom affecting the quality of life and has prevalence of 20–80%. However, it is unclear whether subthalamic nucleus deep brain stimulation (STN–DBS), a well-established treatment for PD, is effective forPD-related pain. Thus, the objective of this meta-analysis was to investigate the efficacy of STN-DBS on PD-related pain and explore how its duration affects the efficacy of STN-DBS. A systematic search was performed using PubMed, Embase, and the Cochrane Library. Nine studies included numerical rating scale (NRS), visual analog scale (VAS), or non-motor symptom scale (NMSS) scores at baseline and at the last follow-up visit and therefore met the inclusion criteria of the authors. These studies exhibited moderate- to high-quality evidence. Two reviewers conducted assessments for study eligibility, risk of bias, data extraction, and quality of evidence rating. Random effect meta-analysis revealed a significant change in PD-related pain as assessed by NMSS, NRS, and VAS (P <0.01). Analysis of the short and long follow-up subgroups indicated delayed improvement in PD-related pain. These findings (a) show the efficacy of STN-DBS on PD-related pain and provide higher-level evidence, and (b) implicate delayed improvement in PD-related pain, which may help programming doctors with supplement selecting target and programming.Systematic Review Registration: This study is registered in Open Science Framework (DOI: 10.17605/OSF.IO/DNM6K).

Deep brain stimulation (DBS) is a promising putative modality for the treatment of refractory psychiatric disorders such as major depression and obsessive-compulsive disorder (OCD). Several targets have been posited; however, a clear consensus on differential efficacy and possible modes of action remain unclear. DBS to the supero-lateral branch of the medial forebrain bundle (slMFB) has recently been introduced for major depression (MD). Due to our experience with slMFB stimulation for MD, and because OCD might be related to similar dysfunctions of the reward system, treatment with slMFB DBS seams meaningful. Here we describe our first 2 cases together with a hypothetical mode of action.We describe diffusion tensor imaging (DTI) fiber tractographically (FT)-assisted implantation of the bilateral DBS systems in 2 male patients. In a selected literature overview, we discuss the possible mode of action. Both patients were successfully implanted and stimulated. The follow-up time was 12 months. One patient showed a significant response (Yale–Brown Obsessive-Compulsive Scale [YBOCS] reduction by 35%); the other patient reached remission criteria 3 months after surgery (YBOCS<14) and showed mild OCD just above the remission criterion at 12 months follow-up.While the hypermetabolism theory for OCD involves the cortico–striato–thalamo–cortical (CSTC) network, we think that there is clinical evidence that the reward system plays a crucial role. Our findings suggest an important role of this network in mechanisms of disease development and recovery. In this uncontrolled case series, continuous bilateral DBS to the slMFB led to clinically significant improvements of ratings of OCD severity. Ongoing research focuses on the role of the reward system in OCD, and its yet-underestimated role in this underlying neurobiology of the disease.

Deep brain stimulation is now accepted as a safe and efficient treatment for movement disorders including selected types of dystonia and dyskinesia. Very little, however, is known about its effect on other movement disorders, particularly for “choreic” movements. Huntington disease is a fatal autosomal-dominant neurodegenerative disorder characterized by movement disorders, progressive cognitive impairment, and psychiatric symptoms. Bilateral chronic stimulation of the internal globus pallidus was performed to control choreic movements in a 60-year-old man with a 10-year history of Huntington disease. Chronic deep brain stimulation resulted in remarkable improvement of choreic movements. Postoperative improvement was sustained after 4 years of follow-up with a marked improvement in daily quality of life.
