Abstract
Acquired demyelinating syndromes (ADS) are a heterogenous group of inflammatory demyelinating conditions that include presentations of optic neuritis, transverse myelitis, and acute demyelinating encephalomyelitis. They can be monophasic or can develop into relapsing episodes of the initial demyelinating event or evolve to include other types of demyelination. Significant progress has been made in differentiating subtypes of ADS that differ in their tendency to relapse and in which anti-inflammatory therapies are effective. Differentiating between these subtypes is important for the optimal management of these patients. Clinical features, labs (especially autoantibodies), and MRI findings can help to differentiate between the different ADS.

Abstract
OBJECTIVES Plasmapheresis (PLEX) and intravenous immunoglobulin (IVIg) are commonly used to treat autoimmune neuromuscular disorders, including myasthenia gravis, acute inflammatory demyelinating polyradiculoneuropathy, chronic inflammatory demyelinating polyradiculoneuropathy, and other autoimmune neurological disorders. The side effect profiles of these therapies vary, and concern has been raised regarding the safety of PLEX in the elderly population. In this study, we have examined the pattern of PLEX and IVIg use for autoimmune neurological disorders at a single facility and in a national database, focusing on the complications in elderly patients. METHODS We performed a retrospective chart review of adult patients at our institution receiving PLEX or IVIg for any autoimmune neuromuscular or neuro-immunological disease. Next, we analyzed the National Inpatient Sample database to confirm the trend in IVIg and PLEX use from 2012 to 2018 for a set of neuromuscular and neuro-immunological primary diagnoses. RESULTS IVIg was overall favored over PLEX. The adverse effects were similar among elderly patients (age ≥65 years) compared with younger patients (<65 years) in our institution, even after adequate matching of patients based on age, sex, and medical history. We examined the National Inpatient Sample dataset and noted increasingly higher frequency of IVIg use, consistent with the findings from our institution or facility. CONCLUSIONS Both PLEX and IVIg are safe therapeutic choices in adult patients with autoimmune neuromuscular disorders and other neuro-immunological diseases and can be safely administered in the appropriate clinical setting.

Abstract
BACKGROUND Acute flaccid paralysis (AFP) is characterized by rapidly progressive limb weakness with low muscle tone. It has a broad differential diagnosis, which includes acute flaccid myelitis (AFM), a rare polio-like condition that mainly affects young children. Differentiation between AFM and other causes of AFP may be difficult, particularly at onset of disease. Here, we evaluate the diagnostic criteria for AFM and compare AFM to other causes of acute weakness in children, aiming to identify differentiating clinical and diagnostic features. METHODS The diagnostic criteria for AFM were applied to a cohort of children with acute onset of limb weakness. An initial classification based on positive diagnostic criteria was compared to the final classification, based on application of features suggestive for an alternative diagnosis and discussion with expert neurologists. Cases classified as definite, probable, or possible AFM or uncertain, were compared to cases with an alternative diagnosis. RESULTS Of 141 patients, seven out of nine patients initially classified as definite AFM, retained this label after further classification. For probable AFM, this was 3/11, for possible AFM 3/14 and for uncertain 11/43. Patients initially classified as probable or possible AFM were most commonly diagnosed with transverse myelitis (16/25). If the initial classification was uncertain, Guillain-Barré syndrome was the most common diagnosis (31/43). Clinical and diagnostic features not included in the diagnostic criteria, were often used for the final classification. CONCLUSION The current diagnostic criteria for AFM usually perform well, but additional features are sometimes required to distinguish AFM from other conditions.

Abstract
PURPOSE OF REVIEW This article reviews the clinical presentation, diagnostic evaluation, treatment, and prognosis of the most common monophasic and relapsing acquired demyelinating disorders presenting in childhood. RECENT FINDINGS Our understanding of neuroimmune disorders of the central nervous system is rapidly expanding. Several clinical and paraclinical factors help to inform the diagnosis and ultimately the suspicion for a monophasic versus relapsing course, including the age of the patient (prepubertal versus postpubertal), presence or absence of clinical encephalopathy, identification of serum autoantibodies (eg, myelin oligodendrocyte glycoprotein [MOG] and aquaporin-4), presence of intrathecally unique oligoclonal bands, and location/extent of radiologic abnormalities. Collaborative international research efforts have facilitated understanding of the safety and efficacy of currently available immunotherapies in children with acquired demyelinating disorders, particularly multiple sclerosis. SUMMARY Although many of the demyelinating disorders presented in this article can affect children and adults across the age spectrum, the clinical and radiologic phenotypes, treatment considerations, and long-term prognoses are often distinct in children.

Abstract
We report an atypical case of a 15-year-old pediatric patient diagnosed with Mycoplasma pneumoniae associated acute transverse myelitis (ATM). The patient had no prodromal or pulmonary symptoms that are commonly associated with mycoplasma infection. Yet, the patient exhibited acute bilateral lower extremity paralysis, paresthesia, decreased sensation at the level of T11 and below, bowel and bladder dysfunction, and thrombocytopenia. Magnetic resonance imaging of the spinal cord revealed transverse myelitis from T10 to the end of the conus medullaris. The patient showed only slow clinical improvement despite therapy consisting of azithromycin, high-dose intravenous methylprednisolone, intravenous immunoglobulin, and plasmapheresis. This report calls attention to the importance of early identification of mycoplasma as an underlying cause of ATM and the potential consequences of delayed detection and treatment: more severe neurologic complications, prolonged hospitalization, and unfavorable clinical outcomes.

Abstract
Neurological emergencies account for about one-third of the highest severity codes attributed in emergency pediatric departments. About 75% of children with acute neurological symptoms presents with seizures, headache, or other paroxysmal events. Life-threatening conditions involve a minor proportion of patients (e.g., less than 15% of children with headache and less than 5% of children with febrile seizures). This review highlights updated insights about clinical features, diagnostic workup, and therapeutic management of pediatric neurological emergencies. Particularly, details will be provided about the most recent insights about headache, febrile seizures, status epilepticus, altered levels of consciousness, acute motor impairment, acute movement disorders, and functional disorders, as well as the role of diagnostic tools (e.g., neuroimaging, lumbar puncture, and electroencephalography), in the emergency setting. Moreover, the impact of the current novel coronavirus disease2019 (COVID-19) pandemic on the evaluation of pediatric neurologic emergencies will also be analyzed.

Abstract
BACKGROUND Patients with transverse myelitis (TM) often present with urinary retention. While many recover their bladder function, some have persistent voiding dysfunction, and both intermediate and long-term outcomes are variable. OBJECTIVE In patients who develop urinary retention requiring clean intermittent catheterization (CIC) at onset of TM, we sought to assess factors associated with improved voiding function and the risk of requiring persistent CIC over time. STUDY DESIGN We reviewed children evaluated at our institution for TM from April 1998 to October 2018. Patients were included if they required CIC at initial presentation of TM. Demographics, initial and follow up neurologic exams were evaluated for their association with a return to baseline volitional voiding after requiring catheterization upon diagnosis of TM, with or without medical therapy. RESULTS Among the 78 patients who presented with TM during the study period, 43 patients required CIC, with median follow up of 2.7 years. When evaluating for demographic or sensorimotor features associated with improvement to baseline voiding function in patients who initially required CIC, preserved lower extremity reflexes at presentation was the only significant prognostic factor (p < 0.05). Additionally, having complete lower motor neurologic recovery was associated with volitional voiding (p < 0.05). Among the 43 patients who were initially catheterizing, 27/43 (62%) were volitionally voiding at median follow up of 7 months from initial presentation, while the remaining 16/43 remained on CIC for a median follow up of 3.6 years. The cumulative risk of remaining on CIC was 60%, 47%, and 42% at 1, 5, and 10 year follow up, respectively, though there was not a significant difference in the rate of bladder recovery if patients had preserved reflexes. DISCUSSION In children with TM who initially developed urinary retention, intact reflexes at presentation were associated with urologic recovery. Additionally, complete neurologic recovery was associated with volitional voiding. While 62% were volitionally voiding at most recent follow-up, the cumulative incidence of dependence on CIC within the first year of diagnosis was 60%, with a relatively few patients regaining volitional voiding by 10 years of follow-up. CONCLUSION Among those initially evaluated for urinary retention in the setting of transverse myelitis, intact lower extremity reflexes on physical exam was associated with improved voiding function at most recent follow-up. However, more than half the patients on CIC at initial presentation required CIC at one year of follow-up. Careful, long-term monitoring of voiding status in patients with TM is recommended, even with improvement of neurological status.

Abstract
This case report reviews the hospital course of a 15-month-old girl admitted to the PICU for acute respiratory failure due to enterovirus infection; who subsequently had multiple extubation failures secondary to acute transverse myelitis. This rare presentation highlights the importance of assessing the neurological status in a patient with rhino-enteroviral respiratory infection and of considering acute transverse myelitis as an etiology for difficulty with extubation.
