Choroid plexus arteriovenous malformations: A systematic review.

To systematically review the reported outcomes and complications of different treatment options for choroid plexus arteriovenous malformations (AVMs), specifically focusing on surgical resection and endovascular embolization. A systematic literature review was performed using a PubMed query for studies published between January 1975 and July 2021. All studies describing the clinical presentation, management, and outcome of confirmed choroid plexus AVM cases were included. A total of 20 studies were included in the final analysis. Of these, 18 were singlepatient case reports, one article contained two patients, and a single study was a cohort of 24 patients. Patient age ranged from one day to 61 years, with a mean of 31.8±20.4 years. Most choroid plexus AVMs were located in the lateral ventricles (14 patients, 70.0%), while there were four (20.0%) located in the third ventricle, and two in the fourth ventricle (10.0%). Almost all patients were treated with surgical resection (18 patients, 90%). In 14 patients (77.8%), complete resection of the AVM was achieved. A residual AVM was reported in one case (5.6%). Most patients were reported to have improved from their presentation status over time (14 patients, 70.0%). Presence or absence of long-term sequelae (e.g., neurologic deficits) were reported for 14 patients (70%). Eleven of these patients (78.6%) were reported to have no neurological sequelae. While data on choroid plexus AVMs remains limited, the available evidence suggests gross total resection of lesions in this location can be safely achieved with subsequent reduction in preoperative symptoms.

Patient-Reported Outcomes After Focused Ultrasound Thalamotomy for Tremor-Predominant Parkinson's Disease.

BACKGROUND: Magnetic resonance-guided focused ultrasound (MRgFUS) has emerged as a precise, incisionless approach to cerebral lesioning and an alternative to neuromodulation in movement disorders. Despite rigorous clinical trials, long-term patient-centered outcome data after MRgFUS for tremor-predominant Parkinson's Disease (TPPD) are relatively lacking. OBJECTIVE: To report long-term data on patient satisfaction and quality of life after MRgFUS thalamotomy for TPPD. METHODS: In a retrospective study of patients who underwent MRgFUS thalamotomy for TPPD at our institution between 2015 and 2022, a patient survey was administered to collect self-reported measures of tremor improvement, recurrence, Patients' Global Impression of Change (PGIC), and side effects. Patient demographics, FUS parameters, and lesion characteristics were analyzed. RESULTS: A total of 29 patients were included with a median follow-up of 16 months. Immediate tremor improvement was achieved in 96% of patients. Sustained improvement was achieved in 63% of patients at last follow-up. Complete tremor recurrence to baseline occurred for 17% of patients. Life quality improvement denoted by a PGIC of 1 to 2 was reported by 69% of patients. Long-term side effects were reported by 38% of patients and were mostly mild. Performing a secondary anteromedial lesion to target the ventralis oralis anterior/posterior nucleus was associated with higher rates of speech-related side effects (56% vs 12%), without significant improvement in tremor outcomes. CONCLUSION: Patient satisfaction with FUS thalamotomy for tremor-predominant PD was very high, even at longer term. Extended lesioning to target the motor thalamus did not improve tremor control and may contribute to greater frequency of postoperative motor- and speech-related side effects.

The use of dupilumab in patients with HIV.

BACKGROUND: The goal of this study was to complete the first Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) based systematic review of dupilumab use in patients living with human immunodeficiency virus (HIV). METHODS: A systematic literature review was performed using PubMed, Google Scholar, Ovid MEDLINE, and Science Direct databases as well as an internal review using University of Virginia's electronic medical record system. All reports of dupilumab use in patients with confirmed HIV were included. RESULTS: 14 published cases comprising 23 patients were identified and included in the review. Additionally, four unpublished cases from our own institution were included for a final cohort of 27 patients. A total of 25 patients (96%) were observed to have a clinical response, defined as improvement or complete resolution of their cutaneous or asthmatic symptoms. In 100% of patients, viral load improved or did not change, and in 80% of patients, CD4 counts remained stable. Side effects occurred in 48% of patients but were self-limited. DISCUSSION AND CONCLUSIONS: All reported cases indicate that dupilumab is safe in patients with HIV with stable CD4 counts and low viral loads. Most patients had significant improvement within 2 months of treatment with mild side effects.
