BACKGROUND: Opsoclonus-myoclonus syndrome is a rare clinical condition that has been associated with neuroblastoma. There are few reported cases of the presence of ANNA-1/anti-Hu antibodies in children with neuroblastoma and opsoclonus-myoclonus, all in children aged less than 3 years. METHODS: We report the new onset of focal seizures without alteration of consciousness and opsoclonus-myoclonus in an 11-year-old girl with ANNA-1/anti-Hu positivity and a paraspinal ganglioneuroblastoma...

Opsoclonus-myoclonus-ataxia (OMA) syndrome typically presents with chaotic eye movements and myoclonus with some patients exhibiting ataxia and behavioural disturbances. The pathogenesis may be inflammatory with an infectious or paraneoplastic trigger. We present a 13-year-old HIV-infected girl who was initially started on highly active antiretroviral therapy (HAART) in March 2013 with a CD4 count of 79 cells/cumm. Initially, the patient did not comply with treatment, resulting in a CD4+ count of 77 cells/mm(3) in November 2015 and prompting a new HAART scheme comprising lamivudine, tenofovir and ritonavir-boosted atazanavir...

AIM: Opsoclonus-myoclonus syndrome (OMS) is a rare, poorly understood condition that can result in long-term cognitive, behavioural, and motor sequelae. Several studies have investigated structural brain changes associated with this condition, but little is known about changes in function. This study aimed to investigate changes in brain functional connectivity in patients with OMS. METHOD: Seven patients with OMS and 10 age-matched comparison participants underwent 3T magnetic resonance imaging (MRI) to acquire resting-state functional MRI data (whole-brain echo-planar images; 2mm isotropic voxels; multiband factor ×2) for a cross-sectional study...

A woman aged 77 years was transferred to our neurocritical care unit for evaluation and treatment of rapidly progressive motor weakness and encephalopathy. Examination revealed an ability to follow simple commands only and abnormal movements, including myoclonus, tongue and orofacial dyskinesias, and opsoclonus. Imaging study findings were initially unremarkable, but when repeated, they demonstrated enhancement of the cauda equina nerve roots, trigeminal nerve, and pachymeninges. Cerebrospinal fluid examination revealed mildly elevated white blood cell count and protein levels...

Opsoclonus Myoclonus Syndrome (OMS) is a rare disease in children which is often associated with neuroblastoma and, therefore, requires treatment by pediatric neurologists and oncologists. The ongoing OMS trial investigates questions related to OMS and potentially underlying neuroblastomas. To support this trial with an adequate IT infrastructure, linkage of neuroblastoma research databases with the OMS electronic data capture (EDC) system was required. Therefore, an EDC system for the OMS trial was developed and integrated into the research infrastructure of the European Network for Cancer Research in Children and Adolescents (ENCCA) project...

A 63-year-old female with no significant past medical history was presented with a 5-day history of progressive opsoclonus-myoclonus, headaches, and fevers. Her workup was significant only for positive West-Nile Virus serum serologies. She received a 2-day course of intravenous immunoglobulin (IvIG). At an 8-week follow up, she had a complete neurological remission. Adult-onset opsoclonus-myoclonus syndrome is a rare condition for which paraneoplastic and infectious causes have been attributed. To our knowledge, this is the first case reported of opsoclonus-myoclonus secondary to West-Nile Virus treated with intravenous immunoglobulin monotherapy...

We aimed to identify new cell-membrane antigens implicated in opsoclonus-myoclonus with neuroblastoma. The sera of 3 out of 14 patients showed IgG electron-microscopy immunogold reactivity on SH-SY5Y neuroblastoma cells. Immunoprecipitation experiments using rat brain synaptosomes and SH-SY5Y cells led to the identification of: (1) thirty-one nuclear/cytoplasmic proteins (including antigens HuB, HuC); (2) seven neuronal membrane proteins, including the Shaw-potassium channel Kv3.3 (KCNC3), whose genetic disruption in mice causes ataxia and generalized muscle twitching...

Dual malignancy has been rarely associated to paraneoplastic syndromes. We describe an unusual case of metachronous small cell lung carcinoma revealed by opsoclonus-myoclonus ataxia syndrome in a 69-year-old patient with known prostate adenocarcinoma, with positive anti-Hu and anti-Yo antibodies and good responsiveness to corticosteroids and chemotherapy.

AIM: Intravenous immunoglobulin (IVIG) is an expensive therapy used in immunodeficiency and autoimmune disorders. Increasing demands and consequent shortages result in a need for usage to conform to guidelines. METHOD: We retrospectively evaluated IVIG use for neuroimmunological indications and adherence to existing guidelines in a major Australian paediatric hospital between 2000 and 2014. RESULTS: One-hundred and ninety-six children (96 male, 100 female; mean age at disease onset 6y 5mo [range 3mo-15y 10mo], mean age at first IVIG dose 7y 2mo [range 3mo-16y 5mo]) received IVIG for neuroimmunological indications during the study period (28...

Opsoclonus-myoclonus syndrome (OMS) is a rare and primarily immune-mediated disease in children and adults. The main symptoms include opsoclonus, myoclonus and ataxia. In children, the symptoms also include irritability, and, over a long-term course, learning and behavioural disturbances. OMS can be idiopathic, parainfectious or occur as a paraneoplastic (tumour-associated) syndrome. Paraneoplastic OMS in children is almost exclusively associated with neuroblastoma, whereas in adults, small cell lung cancer and breast cancer are the main underlying tumours...

We categorized the causes of acute ataxia in the pediatric population-referred to the Division of Neurology-at a large, urban pediatric medical center. Of the 120 cases identified over the past 11 years, post-infectious cerebellar ataxia was the most commonly diagnosed (59%), followed by drug intoxication, opsoclonus-myoclonus ataxia syndrome, episodic ataxia, acute cerebellitis, cerebellar stroke, ADEM, meningitis, cerebral vein thrombosis, Leigh's disease, Miller-Fisher syndrome, and concussion. Among the patients with post-infectious cerebellar ataxia, 85% were 1-6 years old and all had a history of antecedent viral illness...

Neuroblastoma is a childhood cancer derived from cells of neural crest origin. The hallmarks of its enigmatic character include its propensity for spontaneous regression under some circumstances and its association with paraneoplastic opsoclonus, myoclonus, and ataxia. The neurodevelopmental underpinnings of its origins may provide important clues for development of novel therapeutic and preventive agents for this frequently fatal malignancy and for the associated paraneoplastic syndromes.

INTRODUCTION: Opsoclonus-myoclonus-ataxia (OMS) is a rare clinical syndrome, of paraneoplastic infectious, post-infectious, post-vaccinal or idiopathic origin. CASE REPORT: We report a 24-year-old young man who presented with gait disorder preceded by a febrile rash and retroauricular lymph nodes. Three days before admission, he had headache, vertigo, nausea and vomiting followed by gait unsteadiness and movement disorders of limbs and eyes. On examination, he had OMS syndrome...

Adult-onset opsoclonus-myoclonus syndrome (OMS) has been associated with multiple cancers, most commonly small-cell lung carcinoma and breast adenocarcinoma. A 53-year-old woman who presented with OMS was found to have primary central nervous system (CNS) diffuse large B-cell lymphoma. OMS has been described in only 5 cases with non-Hodgkin lymphoma (NHL), and this is only the third reported case of OMS in NHL limited to the CNS. Although the paraneoplastic antibody panel was negative, we presume that the OMS was a paraneoplastic manifestation...
