  • Research Experiences Research Is an Important Part of the Training of Child Neurology Residents at Children’S Mercy Hospital
    Research Experiences Research is an important part of the training of Child Neurology residents at Children’s Mercy Hospital. Training in research starts with the research mentor that each resident is encouraged to engage at the beginning of their child neurology training. The residents are also invited to complete a course on biostatistics and each resident is expected to complete a 1 year course in Quality Improvement and Clinical Safety. As part of the QI course each resident will initiate a QI project which can be presented at CMH Research Day. Each resident is also given the opportunity to present at the yearly Missouri Valley Child Neurology Colloquium. This is a joint meeting with The University of Washington and Saint Louis University Child Neurology programs. Finally, each resident is expected to graduate with at least one first author publication. Over the last 4 years our residents have given over 100 talks (with approximately 20% of these original research or case presentations) and have published 13 papers in peer reviewed journals (including original research and review papers). Faculty Program Director Jean-Baptiste (J.B.) Le Pichon, MD, PhD: Dr. Le Pichon was born in New York City but grew up in France.

Correspondence to: Dr. Torsten Gerriet Blum. Department of Pneumology, Lungenklinik Heckeshorn, Helios Klinikum Emil von Behring, Walterhöferstr. 11, 14165 Berlin, Germany. Email: [email protected]. Abstract: Thymomas are counted among the rare tumour entities which are associated with autoimmune disorders (AIDs) and paraneoplastic syndromes (PNS) far more often than other malignancies. Through its complex immunological function in the context of the selection and maturation of T cells, the thymus is at the same time highly susceptible to disruptive factors caused by the development and growth of thymic tumours. These T cells, which are thought to develop to competent immune cells in the thymus, can instead adopt autoreactive behaviour due to the uncontrolled interplay of thymomas and become the trigger for AID or PNS affecting numerous organs and tissues within the human body. While myasthenia gravis is the most prevalent PNS in thymoma, numerous others have been described, be they related to neurological, cardiovascular, gastrointestinal, haematological, dermatological, endocrine or systemic disorders. This review article sheds light on the pathophysiology, epidemiology, specific clinical features and therapeutic options of the various forms as well as courses and outcomes of AID/PNS in association with thymomas.

  • For Sick Children, Glasgow; Great Ormond Street Hospital, London; and Guy's and St Thomas Evelina Children's Hospital, London, UK
    MOVEMENT DISORDERS OUTCOME OF OPSOCLONUS-MYOCLONUS SYNDROME Long-term neurologic sequelae and predictors for disease outcome were identified in 101 patients diagnosed with opsoclonus-myoclonus syndrome (OMS) over a 53-year period at Royal Hospital for Sick Children, Glasgow; Great Ormond Street Hospital, London; and Guy's and St Thomas Evelina Children's Hospital, London, UK. Median age at disease onset was 18 months (range 3 months to 8.9 years). Neuroblastoma was detected in 21% of patients (40% in those born after 1990). A preceding illness was reported in 56 patients (upper respiratory tract infection, gastroenteritis, and nonspecific), and 8% had been vaccinated within one month of symptom onset. Treatment of OMS consisted of steroids in 87%, none in 12%, and IVIg in 1 case. Median follow-up was 7.3 years (range 3-32 years). Response was good in 35% and moderate in 60%. The course was chronic-relapsing in 61% patients and monophasic in 7%, and acute exacerbations were frequent in 32%. At last review, 60% had residual motor problems, 66% speech abnormalities, 51% learning disability, and 46% behavior problems. One third had normal intellectual outcome and were asymptomatic. A severe initial presentation in 82% patients predicted a chronic course and later learning disability. Cognitive impairment occurred in patients younger at disease onset. A chronic-relapsing course was associated with motor, speech, cognitive, and behavior problems. (Brunklaus A, Pohl K, Zuberi SM, de Sousa C.

Gorman, MD Neurol Neuroimmunol Neuroinflamm 2021;8:e1079. doi:10.1212/NXI.0000000000001079 Abstract Background and Objectives Opsoclonus-myoclonus syndrome (OMS) is a rare autoimmune disorder associated with neuroblastoma in children, although idiopathic and postinfectious etiologies are present in children and adults. Small cohort studies in homogenous populations have revealed elevated rates of autoimmunity in family members of patients with OMS, although no differentiation between paraneoplastic and nonparaneoplastic forms has been performed. The objective of this study was to investigate the prevalence of autoimmune disease in first-degree relatives of pediatric patients with paraneoplastic and nonparaneoplastic OMS. Methods A single-center cohort study of consecutively evaluated children with OMS was performed. Parents of patients were prospectively administered surveys on familial autoimmune disease. Rates of autoimmune disease in first-degree relatives of pediatric patients with OMS were compared using Fisher exact t test and χ2 analysis: (1) between those with and without a paraneoplastic cause and (2) between healthy and disease (pediatric multiple sclerosis [MS]) controls from the United States Pediatric MS Network. Results Thirty-five patients (18 paraneoplastic, median age at onset 19.0 months; 17 idiopathic, median age at onset 25.0 months) and 68 first-degree relatives (median age 41.9 years) were enrolled.

Diagnostic manuals were also consulted.Results: PNEs Conversion Disorder. can be categorized in: physiological events – including hypoxic events, sleep disorders, movement disorders and migraine related disorders – and psychogenic nonepileptic events (mainly conversion disorder; factitious disorder, malingering and panic disorder are also discussed). Around 15% of the patients referred to epilepsy centers actually present PNEs. A significant number of these events does not need treatment and presents spontaneous remission.Conclusion: physicians should be able to identify PNEs, avoiding an incorrect epilepsy diagnosis and its implications, such as unnecessary tests and iatrogenic pharmacotherapy, as well as negative psychosocial consequences for both the patient and the family. 1 Médica Residente em Psiquiatria no Hospital de Clínicas da Universidade Federal do Paraná (UFPR) 2 Professor Adjunto do Departamento de Pediatria da Universidade Federal do Paraná (UFPR), Diretor do Centro de Neuropediatria do Hospital de Clínicas da UFPR Correspondence to: Mariana Richartz Schwind Hospital de Clínicas Universidade Federal do Paraná (HC/UFPR) Centro de Neuropediatra HC/UFPR.

This syndrome develops autoantibodies in combination with certain neurological syndromes and cancers, such as anti-HuD antibodies in encephalomyelitis with small cell lung cancer and anti-Yo antibodies in cerebellar degeneration with gynecological cancer. These autoantibodies have roles in the diagnosis of neurological diseases and early detection of cancers that are usually occult. Most of these autoantibodies have no pathogenic roles in neuronal dysfunction directly. Instead, antigen-specific cytotoxic T lymphocytes are thought to have direct roles in neuronal damage. The recent discoveries of autoantibodies against neuronal synaptic receptors/channels produced in patients with autoimmune encephalomyelitis have highlighted insights into our understanding of the variable neurological symptoms in this disease.

Korczak Specialist Hospital, Slupsk, Poland 3Department of Neurological-Psychiatric Nursing, Medical University of Gdansk, Poland ABSTRACT Aim of the study. The pandemic state of COVID-19 has resulted in new neurological post-infection syndromes. Recently, several papers have reported ataxia-myoclonus syndrome following SARS-CoV-2 infection. The aim of this study was to present our two cases and compare them to previously reported cases. Materials and methods. We present two video-accompanied new cases with ataxia-myoclonus syndrome following SARS- -CoV-2 infection and discuss the studies published so far. Results. Ataxia-myoclonus syndrome, isolated myoclonus, opsoclonus-myoclonus syndrome as post-COVID-19 syndrome following infection have been described in 16 patients (including our two cases). Patients have been treated with intravenous immunoglobulins and/or steroids except for 4 patients, which resulted in a significant improvement within 1–8 weeks. Conclusions and clinical implications. The increasing number of patients with a similar symptomatology shows a significant relationship between COVID-19 infection and ataxia-myoclonus syndrome. The subacute onset of neurological symptoms after a resolved COVID-19 infection and prominent response to immunotherapy may suggest that the neurological manifestations are immune-mediated.
