RESUMEN
PURPOSE OF REVIEW: Neurosarcoidosis is a rare manifestation of sarcoidosis that is challenging to diagnose. Biopsy confirmation of granulomas is not sufficient, as other granulomatous diseases can present similarly. This review is intended to guide the clinician in identifying key conditions to exclude prior to concluding a diagnosis of neurosarcoidosis. RECENT FINDINGS: Although new biomarkers are being studied, there are no reliable tests for neurosarcoidosis. Advances in serum testing and imaging have improved the diagnosis for key mimics of neurosarcoidosis in certain clinical scenarios, but biopsy remains an important method of differentiation. Key mimics of neurosarcoidosis in all cases include infections (tuberculosis, fungal), autoimmune disease (vasculitis, IgG4-related disease), and lymphoma. As neurosarcoidosis can affect any part of the nervous system, patients should have a unique differential diagnosis tailored to their clinical presentation. Although biopsy can assist with excluding mimics, diagnosis is ultimately clinical.

Sarcoidosis is a disease characterized by non-caseating granulomas that can involve the central nervous system as neurosarcoidosis. This challenging disease is currently managed with high dose steroids, and sometimes the addition of infliximab. Other TNA-alpha inhibitors have not been studied as rigorously. We discovered ten neurosarcoidosis patients who were on an alternative TNA-alpha inhibitor, adalimumab. Eight patients had a positive response clinically and radiographically to adalimumab.

Purpose of Review: Lack of consistent data and guidance have led to variations between clinicians in the management of pregnancy in women with multiple sclerosis (MS). Pregnant and/or lactating women are often excluded from clinical trials conducted in MS, and thus, the labeling for most disease-modifying therapies (DMTs) excludes use during pregnancy. This has led to heterogeneity in interpretation and labeling regarding the safety of DMTs during pregnancy and lactation and the required preconception washout periods. This review identifies key themes where there is conflicting information surrounding family planning and pregnancy in MS, focusing on the most common discussion points between physicians and patients during preconception planning, pregnancy, postpartum, and lactation. The goal was to inform the patient-physician conversation and provide best practice recommendations based on expert clinical expertise and experience. Recent Findings: We outline the latest evidence-based data for DMT use during pregnancy and lactation, the effect of MS on fertility and fertility treatments, the risk of adverse pregnancy and delivery outcomes, the risk of postpartum relapse, and immunization and clinical imaging safety during pregnancy and breastfeeding. Summary: Management of family planning and pregnancy in patients with MS requires the most current information. Health care providers should discuss family planning early and frequently with patients with MS, and partners where practicable. Because management of pregnant people with MS will often require a risk/benefit analysis of their needs, shared decision-making in family planning discussions is emphasized. Additional data are needed for specific and underrepresented populations with MS (e.g., single parents or those from the LGBTQ+ community) and those at risk of racial and socioeconomic disparities in care. Pregnancy registries and the design and conduct of clinical trials focused on pregnant and lactating patients should provide additional data to guide the ongoing management of patients with MS.
RESUMEN
Background: Intersection of gender and race and/or ethnicity in academic medicine is understudied; we aim to understand these factors in relation to scholarly achievements for neurology faculty. Methods: Faculty from 19 US neurology departments completed a survey (2021-2022) to report rank, leadership positions, publications, funded projects, awards, and speaker invitations. Regression analyses examined effects of gender, race, and their intersectionality on these achievements. Women, Black/Indigenous/People of Color (BIPOC), and BIPOC women were comparator groups. Results: Four hundred sixty-two faculty responded: 55% women, 43% men; 31% BIPOC, 63% White; 21% BIPOC women, 12% BIPOC men, 36% White women, 31% White men. Men and White faculty are more likely to be full professors than women and BIPOC faculty. The number of leadership positions, funded projects, awards, and speaker invitations are significantly greater in White compared to BIPOC faculty. Relative to BIPOC women, the number of leadership positions is significantly higher among BIPOC men, White women, and White men. Publication numbers for BIPOC men are lower, number of funded projects and speaker invitations for White women are higher, and number of awards among White men and White women is higher compared to BIPOC women. Discussion: Our study highlights that inequities in academic rank, award number, funded projects, speakership invitations, and leadership roles disproportionately impacted BIPOC women. More studies are needed to evaluate gender and race and/or ethnicity intersectionality effects on faculty achievements, reasons for inequities, recognition, and potential solutions.
RESUMEN
Sarcoidosis is a granulomatous inflammatory disease that rarely affects the central nervous system as neurosarcoidosis. Neurosarcoidosis can affect any part of the nervous system causing a wide variety of clinical presentations ranging from seizures to optic neuritis. Here, we highlight rare cases of obstructive hydrocephalus in patients with neurosarcoidosis to make clinicians aware of this potential disease complication.

BACKGROUND: Neuromyelitis optica spectrum disorder (NMOSD) is a rare autoimmune neurological disorder associated with antibodies to aquaporin-4 (AQP4). NMOSD has been thought to follow a progressive disease course, with step-wise accumulation of disability over time, even in patients undergoing immunosuppressive/immunomodulatory therapy. The influence of factors such as AQP4 seropositivity, AQP4 serum titer levels, and administration of plasmapheresis on NMOSD prognosis is, as yet, unclear. METHODS: We performed a retrospective chart review of 53 persons with NMOSD at Duke University Hospital-collecting data on longitudinal disease course, imaging, demographics, and serum AQP4 titers (measured using the ELISA or FACS method). Most patients in our cohort were treated with high-dose corticosteroids and, following diagnosis, received maintenance immunosuppressive/immunomodulatory therapies. Longitudinal data on EDSS scores were used to calculate the slope of disability over time for each participant. We additionally investigated the correlation between initial AQP4 seropositivity, initial AQP4 serum titer levels, and treatment with plasmapheresis on disability progression for each participant. RESULTS: Contrary to current views on NMOSD disease course, the majority of our participants showed either no change (31.9%) or improvement (27.1%) in disability over time. Our results additionally revealed no significant association between clinical prognosis and initial AQP4 seropositivity (p = 0.830), initial AQP4 serum titer levels (p = 0.338), or administration of plasmapheresis (p = 0.1149). CONCLUSIONS: Our study presents a contemporary view of the clinical course of NMOSD and shows a more favorable view of its disease course than prior studies (performed before high-efficacy disease modifying therapies became widely-used for this patient population). Most patients in this study received treatment with high-dose corticosteroids following NMOSD flares, as well as a variety of maintenance immunosuppressive therapies. The results of this study cannot shed light on the disease course of untreated NMOSD. Our findings additionally challenge the theory that AQP4 seropositivity or serum titer levels at time of diagnosis may be used to effectively predict NMOSD prognosis. While we were unable to find evidence supporting a favorable effect of plasmapheresis administration on disease outcomes, further research is needed to determine the role plasmapheresis ought to play in the treatment of NMOSD.

OBJECTIVE: To investigate the efficacy of cryocompression therapy to prevent chemotherapy-induced peripheral neuropathy. METHODS: This single-institution, randomized, self-controlled trial of cryocompression enrolled gynecologic cancer patients planned for five to six cycles neurotoxic chemotherapy. Exclusion criteria were prior neurotoxic chemotherapy or baseline peripheral neuropathy. Participants were randomized to cryocompression on dominant versus non-dominant hand and foot (treatment), with no intervention on the opposite side (control). Compression socks and gloves and ice bags were applied 15 minutes before, during, and 15 minutes after infusion. Primary outcome measures included the PNQ (Patient Neurotoxicity Questionnaire) and the Semmes-Weinstein monofilament test; secondary outcomes included the FACT/GOG-NTX (Functional Assessment of Cancer Therapy/Gynecologic Oncology Group - Neurotoxicity) and patient acceptability and tolerability. Sixty patients completing the study were necessary to detect a 70% reduction in the odds of PNQ grade C or higher peripheral sensory neuropathy with 80% power. RESULTS: Ninety-one patients were enrolled from January 2021 to October 2022; 69 were eligible for final analysis. Of the 91 patients, 64.8% were White, 30.8% were Black, and 1.1% were Hispanic or Latina. With successive cycles, more patients had sensory PNQ grade C or higher neuropathy on the control side compared with the cryocompression side. Cryocompression decreased the odds of sensory neuropathy (PNQ grade C or higher) by 46% at final visit (odds ratio 0.54, 95% CI 0.31-0.94; P =.03). There was no difference in tactile sensitivity based on the monofilament test between sides at the final visit. At the final visit, average FACT/GOG-NTX-11 (Functional Assessment of Cancer Therapy/Gynecologic Oncology Group - Neurotoxicity 11 Item Version) scores were significantly lower on the cryocompression than the control side (estimate -0.97, 95% CI -1.89 to -0.06; P =.04), as were FACT/GOG-NTX-4 (Functional Assessment of Cancer Therapy/Gynecologic Oncology Group - Neurotoxicity 4 Item Version) scores (estimate -0.35, 95% CI -0.64 to -0.05; P =.02). More than 85% of patients assessed the intervention as acceptable and tolerable. CONCLUSIONS: Cryocompression therapy reduces subjective chemotherapy-induced peripheral sensory neuropathy in patients who are receiving paclitaxel or cisplatin for gynecologic cancer.

BACKGROUND/INTRODUCTION: Myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) is a chronic demyelinating disorder that has been increasingly recognized since the serum antibody became commercially available in 2017. The most common clinical presentation is optic neuritis, and first line acute treatment is intravenous (IV) steroids. However, there are many questions that remain unanswered. For clinicians and patients, the primary question is whether relapses will occur and whether to treat with chronic therapy. METHODS: This retrospective chart review examined characteristics of thirty-three known adult MOGAD cases at a single institute. Data was collected on patient demographics, clinical presentation, objective diagnosis with MRI and serum antibody levels, acute and chronic treatment and disease outcomes. RESULTS: Our MOGAD cases revealed a slight female to male predominance of 1.5:1. No racial groups were affected disproportionately, and age of symptom onset spanned a large range with a median of 40 years. The most common clinical and radiologic presentation was optic neuritis followed by transverse myelitis and brainstem symptoms/lesions. IV methylprednisolone was used in the vast majority of cases for acute treatment. 83.3% of our patients were treated with chronic therapy at some point during their disease course. Therapies include rituximab, IVIG, ocrelizumab, mycophenolate mofetil and ofatumumab. The majority of our patients were treated with rituximab and we did not see a significant benefit of yearly relapse reduction for rituximab versus other therapies. Our cohort had a higher-than- expected percentage of cases with relapsing disease (56.3%) compared to monophasic (43.8%). DISCUSSION/CONCLUSION: Our study confirms prior data regarding the demographics, clinical presentation and radiologic presentation of MOGAD. There is no consensus on whether maintenance therapy should be started for MOGAD cases with a single clinical event. Our cohort showed a higher relapse rate than has been reported previously and all known relapses occurred within one year of diagnosis. More data is necessary to confirm risk of relapse in the years following diagnosis. In addition, further data on biomarkers are needed to predict the disease course could help guide management.

Hospital neurologists participate at the forefront of managing fulminant acute and subacute onset epilepsy, frequently attributed to autoimmune encephalitis (AE). As the recognition of antibody-mediated AE grows, there is a growing number of patients who are treated as antibody-negative AE. While antibody-negative autoimmune processes should be considered in the setting of acute and subacute onset of fulminant epilepsy, other causes must be considered before subjecting patients to long-term immunomodulatory treatments and other potential therapeutic toxicities. We present the case of a previously healthy young man who presented with new-onset refractory seizures treated with escalating doses of anti-epileptic drugs as well as immunosuppression for presumed autoimmune epilepsy. He developed valproic acid induced hepatotoxicity requiring liver transplantation and was later found to have a POLG mutation. We discuss the presentation of POLG mutations as well as the diagnosis of seronegative autoimmune encephalitis. We highlight the need for a broad differential when evaluating new onset refractory seizures in an otherwise healthy person.
RESUMEN
Management of multiple sclerosis and neuroimmunologic disorders has become increasingly complex because of the expanding number of recognized neuroimmune disorders, increased number of therapeutic options, and multidisciplinary care management needs of people with multiple sclerosis and neuroimmunologic disorders. More subspecialists are needed to optimize care of these patients, and many fellowship programs have been created or expanded to increase the subspecialty workforce. Consequently, defining the scope and standardizing fellowship training is essential to ensure that trainees receive high-quality training. A workgroup was created to develop a consensus fellowship curriculum to serve as a resource for all current and future training programs. This curriculum may also serve as a basis for future accreditation efforts.
RESUMEN
Multiple sclerosis (MS) is an autoimmune inflammatory demyelinating central nervous system disorder that is more common in women, with onset often during reproductive years. The female:male sex ratio of MS rose in several regions over the last century, suggesting a possible sex by environmental interaction increasing MS risk in women. Since many with MS are in their childbearing years, family planning, including contraceptive and disease-modifying therapy (DMT) counselling, are important aspects of MS care in women. While some DMTs are likely harmful to the developing fetus, others can be used shortly before or until pregnancy is confirmed. Overall, pregnancy decreases risk of MS relapses, whereas relapse risk may increase postpartum, although pregnancy does not appear to be harmful for long-term prognosis of MS. However, ovarian aging may contribute to disability progression in women with MS. Here, we review sex effects across the lifespan in women with MS, including the effect of sex on MS susceptibility, effects of pregnancy on MS disease activity, and management strategies around pregnancy, including risks associated with DMT use before and during pregnancy, and while breastfeeding. We also review reproductive aging and sexual dysfunction in women with MS.
RESUMEN
Multiple sclerosis (MS) is a chronic autoimmune condition primarily affecting young adults. As there are numerous uncertainties faced by young women of childbearing age who are living with this chronic condition and the gender ratio is increasingly skewed towards women, it has become critical to define a clear approach to questions of disease management prior to and during pregnancy. With the approval of B cell depletion therapy for treatment of relapsing remitting and primary progressive MS, we explore the available data on using this type of therapy in the setting of pregnancy. We also provide recommendations regarding use of B-cell depleting therapies for patients who are considering or attempting conception.

BACKGROUND: Acute disseminated encephalomyelitis has been understood as a monophasic, often post-infectious illness that predominantly affects the pediatric population. Though that describes the majority of cases, exceptions do exist. In this case report, we present an adult case of recurrent disseminated encephalomyelitis (DEM) and review the available literature on this clinical entity. METHODS: PubMed search performed using the terms "MDEM" and "Recurrent ADEM" in April 2018. A total of 23 items resulted for the first search and another 142 for the second. We selected articles that described cases of recurrent ADEM with a preference for those publications describing adult cases and those written in English language. CONCLUSION: Recurrent disseminated encephalomyelitis is a distinct clinical entity that has features which overlap with multiple sclerosis, making it imperative to distinguish the two. Our case presentation and accompanying literature review highlights the limited scope of data available on recurrent DEM and the need for further study.

Recently, immune checkpoint inhibitors have revolutionized cancer care by enhancing anti-tumor immunity. However, by virtue of stimulating the immune system, they can lead to immune-related adverse events (irAEs). Neurologic irAEs are uncommon but are becoming increasingly recognized and can be quite serious or even fatal. Furthermore, central nervous system (CNS) manifestations may be difficult to distinguish from CNS metastases, posing management challenges. Here, we describe a patient who developed exacerbation of sarcoidosis leading to CNS involvement following dual checkpoint blockade with nivolumab and ipilimumab for metastatic melanoma and review the relevant literature.
RESUMEN
Immune checkpoint inhibitors have improved patient survival outcomes in a variety of advanced malignancies. However, they can cause a number of immune-related adverse effects (irAEs) through lymphocyte dysregulation. Central nervous system (CNS) irAEs are rare, but as the number of indications for checkpoint inhibitors increases, there has been emergence of CNS immune-mediated disease among cancer patients. Given the relatively recent recognition of checkpoint inhibitor CNS irAEs, there is no standard treatment, and prognosis is variable. Therefore, there is a great need for further study of checkpoint inhibitor-induced CNS irAEs. Here, we present two unique cases of nivolumab-induced autoimmune encephalitis in patients with non-small cell lung cancer and review the available literature.
