Anti-NMDA Receptor Encephalitis Related to Renal Cell Carcinoma: A Case Report.

Anti-NMDA receptor (NMDAR) encephalitis is characterized by a well-defined neuropsychiatric syndrome and CSF antibodies against the GluN1 subunit of the NMDAR. 40% of cases are related to underlying tumors, the vast majority ovarian teratomas (94%). We report a case of anti-NMDAR encephalitis associated with renal cell carcinoma (RCC). A 20-year-old female presented to the ED with behavioral changes, involuntary movements, tachycardia, and alternating obtundation with agitation which progressed over 3 weeks. Involuntary movements were severe, requiring intubation and sedation for control, and were accompanied by rhabdomyolysis. Brain MRI showed bilateral mesiotemporal T2/FLAIR hyperintensities. Anti-NMDAR antibodies were present in the serum (1:640) and CSF (1:320). Malignancy screening revealed a renal mass concerning for RCC, which was confirmed upon resection. She was started on high dose IV methylprednisolone and plasmapheresis, followed by rituximab. Lack of response led to escalating immunotherapy with cyclophosphamide. Clinical course was complicated by prolonged ICU admission, prolonged sedation, severe dysautonomia and bacteremia. Improvement began 2 months after immunotherapy, and she was discharged to rehabilitation 100 days after admission with mild neuropsychiatric symptoms. Repeat malignancy screenings, including whole-body imaging and transvaginal ultrasound were consistently negative. Herein, we describe a case of definite anti-NMDAR encephalitis in the setting of newly diagnosed RCC. This case illustrates how tumors other than ovarian teratomas may act as immunological triggers, as well as the complex and prolonged symptomatic and immunosuppressive therapies required in severe presentations of anti-NMDAR encephalitis.

Prevalence of multiple sclerosis and treatment utilization in a large, highly diverse population.

BACKGROUND: Despite advances in algorithms for identifying people with MS (PwMS) in large data sets, limited data exists on regional prevalence, or prevalence and care in minority populations. OBJECTIVES: To report the 7-year (01/01/2012-12/31/2018) prevalence and demographics of MS and disease-modifying therapy (DMT) utilization in a large, diverse population. METHODS: This retrospective analysis used the OneFlorida Data Trust, which captures health data from >15 million Floridians across 10 constituent organizations. A validated algorithm identified subjects with MS. DMTs were identified using RxNorm concept unique identifiers and National Drug Codes. Results were stratified across age, sex, race-ethnicity, and location. RESULTS: Of 6,638,649 adults in the database, the algorithm identified 9681 PwMS. Overall prevalence per 100,000 was 145.83. MS prevalence was considerable in women of all races and ethnicities ranging from 138.86 to 253.76 per 100,000. 52.6% of PwMS had one or more DMT prescription. DMT prescription was more likely in Hispanic PwMS. CONCLUSION: Prevalence analysis of the OneFlorida Data Trust revealed a substantial burden of disease in women of all races and ethnicities. Variation in treatment utilization among demographic subgroups underscores the need for additional studies to assess health care disparities in MS at the population level.

Movement for multiple sclerosis: a multi-site partnership for practice and research.

While dance programs for people with Parkinson's disease (PD) have been developed globally over the past two decades, dance programs for people with multiple sclerosis (MS) are just emerging. This article introduces three dance for MS programs and a multi-site partnership that was developed to evaluate and advance a model for dance for MS programs. The program partners convened over 2 days to share program models, consider current and planned program evaluations, and identify unique challenges and promising practices for delivering safe and effective dance for MS programs. This paper presents the findings of this convening and recommendations for dance for MS programs.Background:While dance programs for people with Parkinson's disease (PD) have been developed globally over the past two decades, dance programs for people with multiple sclerosis (MS) are just emerging.

Recommendations are offered to guide safe and evidence-based dance for MS practices.

Corticosteroids lead to short-term improvement in cerebral amyloid angiopathy-related inflammation.

BACKGROUND: Cerebral amyloid angiopathy - related inflammation (CAA-ri) is an uncommon manifestation of CAA. METHODS: Single-center, retrospective review of all charts with ICD-code I68.0 (CAA) from 2/2/2016-1/1/2020. RESULTS: Of 152 CAA cases, 13 (8.6%) were consistent with CAA-ri. Corticosteroid-treatment led to short-term reduction in modified Rankin Scale scores (2.6 ± 1.4 vs. 1.6 ± 1.5; p = 0.01) and T2/FLAIR lesion volume (78.1 ± 52.2 cm3 vs. 30 ± 30.9 cm3, p < 0.01) as well as short-term improvement in post-treatment Clinical Global Impression - Global Change scores compared to pre-treatment scores (clinical: 6 ± 1 vs. 2.6 ± 1.3, p = 0.03; radiological: 4.6 ± 1.9 vs. 1.2 ± 0.4, p = 0.03). INTERPRETATION: Corticosteroid-treatment leads to clinical and radiological short-term improvement (class IV evidence).
