Abstract
Objective: To study the clinical characteristics and treatment of pediatric opsoclonus-myoclonus syndrome (OMS). Methods: We analyzed the clinical data of nine children OMS between June 2017 and Nov 2020. Results: Nine children (M/F = 3:6, median onset age was 18 months) diagnosed with OMS were included in the study. Before onset, human rhinovirus and respiratory syncytial virus were seen in one patient, respectively. And one patient received Japanese encephalitis vaccination. Three patients had neuroblastoma, and one patient had ganglioneuroblastoma. All patients' symptoms were improved after receiving surgery (for four patients with tumor), intravenous human immunoglobulin and pulsed methylprednisolone. However, four patients without mass relapsed and became relapse free after rituximab treatment. The relapse rate was 44.4% (4/9). The OMS severity score at the last follow-up was significantly lower than the OMS severity score at onset (3.0 ± 1.0 vs. 11.0 ± 2.2, paired-samples t-test, P < 0.001). All patients had at least one item of neurological symptoms or neuropsychological disturbances. Conclusion: For pediatric OMS, human rhinovirus infection and respiratory syncytial virus infection can be seen before onset. Rituximab is effective in reducing relapse. Improving recognition and long-term prognosis in OMS is urgent.

Abstract
Opsoclonus, an uncommon clinical sign, and is often described in the context of opsoclonus myoclonus ataxia syndrome (OMAS). OMAS may be paraneoplastic or postinfectious. However, opsoclonus with or without OMAS may occur in association with a wide gamut of infections. Infection-associated opsoclonus/OMAS (IAO) needs recognition as a separate entity, since it demands relatively brief immunosuppression, symptomatic treatment, and has a better outcome. Case records of children, who presented with opsoclonus to a tertiary-care teaching hospital of North India over a period of 1 year (2017-2018), were reviewed. Those with opsoclonus in the setting of an acute infection/febrile illness (symptomatic opsoclonus; IAO) were included. Of 15 children with opsoclonus, 6 children [median age: 42 months (range: 8 months to 7 years); 2 boys] had opsoclonus associated with an infective or febrile illness. Additional clinical findings in these children included myoclonus (n = 2), ataxia (n = 4) and behavioral abnormalities (n = 4). All these patients had an associated neurologic or nonneurologic illness- scrub typhus (n = 1), tuberculous meningitis (n = 1), mumps encephalitis (n = 1), brainstem encephalitis (n = 1), acute cerebellitis (n = 1), and subacute sclerosing panencephalitis (SSPE, n = 1). Children with acute cerebellitis, brainstem encephalitis, and mumps encephalitis were treated with steroids while those with scrub typhus, tuberculosis, and SSPE were treated with antibiotics, antitubercular therapy, and Isoprinosine, respectively. None of them needed long-term maintenance immunotherapy. The evaluation for tumor was negative in all. Three of the 6 children are functionally normal at the last follow-up. Acute neuro infections may trigger opsoclonus. A careful analysis of clinical data and suitable investigations can help differentiate these children from those with OMAS. This distinction may avoid unwarranted long-term immunosuppression.

Abstract
BACKGROUND Neurological complications associated with influenza (NCI) are rare events in adults with seasonal influenza. Information about the characteristics of neurological complications and the burden of disease has been limited to case reports, mainly during the pandemic 2009. Influenza-associated encephalopathy/encephalitis (IAE) is one of the most severe and frequently reported NCI, mostly caused by influenza A. Isolated case reports exist about NCI caused by influenza B. OBJECTIVES The aim of this single center retrospective study is the better understanding of the frequency and the characteristics of NCI in adults in season 2017-2018, depending on the influenza subtype A or B. STUDY DESIGN We reviewed 874 adult patients with laboratory confirmed influenza admitted to the Christian Doppler University Hospital Salzburg, Austria from December 2017 until March 2018 looking for NCI. RESULTS 37 (4 %) of the 874 patients with confirmed influenza had NCI. 4 (11 %) had influenza A and 33 (89 %) had influenza B. IAE was the most frequent complication diagnosed in 24 (65 %) patients, of whom all but one had influenza B and 3 (13 %) had neurological residuals. Moreover 6 (16 %) had isolated epileptic seizures, 2 (5 %) had acute inflammatory demyelinating polyneuropathy (AIDP), and 5 (14 %) were classified as having infection-associated stroke. CONCLUSIONS We report an incidence of 4 % for NCI and a high frequency of IAE caused by subtype B. Therefore, we recommend considering both influenza A and B as an etiologic factor of encephalopathy and other neurological disease in adults.

Abstract
Infections caused by various viruses, mainly belonging to the Herpesviridae family, can trigger the autoimmune process in the CNS in children. This can break brain immune tolerance and induce many molecular and cellular pathways of the immune response. This can lead to the appearance of neuronal auto-antibodies to intracellular, cell-surface or extracellular synaptic antigens. Children may also display a wide spectrum of neurological problems from encephalitis to obsessive–compulsive or tic disorders. In these cases, patients rarely respond to traditional treatment, based on antiviral or/and symptomatic drugs, but early immunotherapy is very effective. The implementation of routine immune tests in all children with acute neurological disorders should be recommended.

Abstract
Opsoclonus myoclonus syndrome (OMS) is an inflammatory neurological disorder, which is characterized by chaotic uncontrolled movements of the eyes and involuntary jerk-like movements of the body. Different modalities of treatment have been described in medical literature to treat OMS. Immunomodulatory treatment with either steroids or intravenous immunoglobulin has been considered. Our case was a 14-year-old boy who presented with fever, mild confusion, without any seizures or focal deficits. On examination, he had opsoclonus in his eyes and had cortical myoclonus in his hands and body. On evaluation, he had low platelets, normal metabolic workup, normal brain imaging, and cerebrospinal fluid showed lymphocytic pleocytosis. He was managed conservatively and had spontaneous improvement in opsoclonus myoclonus by 5th day of his illness and complete recovery in 2 weeks. Although dengue is primarily considered hematotropic virus, it can involve nervous system as well and manifest with OMS.

Abstract
Infectious diseases remain the most common cause of neurological disability in the world. A number of movement disorders can develop in adults and children in response to infections. These can occur in isolation or as part of a broader neurological illness, with movement abnormalities consequent to an encephalopathy or a broader brain dysfunction. While most infection-related movement disorders are direct consequences of an active infectious process affecting cerebral structures implied in the motor network, at times a delayed immune-mediated process in response to a previous infectious is responsible for the neurological dysfunction. This immunological response can occur as a consequence of a number of pathogens, and develop at variable times after the initial infection. The most common infection-mediated autoimmune movement disorders are chorea, which is especially common in children, and other hyperkinetic disorders, but Parkinsonism and other hypokinetic movement disorders may also occur.

Abstract
Saccades are rapid eye movements designed to shift the fovea to objects of visual interest. Abnormalities of saccades offer important clues in the diagnosis of a number of movement disorders. In this review, we explore the anatomy of horizontal and vertical saccades, discuss practical aspects of their examination, and review how saccadic abnormalities in hyperkinetic and hypokinetic movement disorders aid in diagnosis, with video demonstration of classic examples. Documentation of the ease of saccade initiation, range of motion and conjugacy of saccades, speed and accuracy of saccades, dynamic saccadic trajectory, and the presence or absence of saccadic intrusions and oscillations are important components of this exam. We also provide a practical algorithm to demonstrate the value of saccades in the differential diagnosis of the movement disorders patient.

Abstract
Opsoclonus-myoclonus syndrome (OMS) is a rare neurologic disorder characterized by opsoclonus, myoclonus, ataxia and behavioral disturbance. In the pathogenesis, an autoimmune process with infectious or paraneoplastic trigger has been suggested. We describe the case of a 22-month-old girl with OMS following rotavirus gastroenteritis. Rotavirus should be considered in the differential diagnosis of OMS in children.

Abstract
Background: Movement disorders (MDs) associated with infections remains an important debilitating disorder in the Asian countries. Objectives: The objective of the following study is to report the clinical and imaging profile of a large cohort of patients with MDs probably associated with infection. Materials and Methods: This was a chart review of 35 patients (F:M-15:20) presenting with MD in the Neurology services of National Institute of Mental Health and Neurosciences, India. The demographic profile, type of infection, time from infection to MD, phenomenology of MD and magnetic resonance imaging (MRI) findings were reviewed. Results: The mean age at presentation was 22.6 ± 13.3 years, (5-60), age of onset of MD was 15.7 ± 15 years, and duration of symptoms was 6.9 ± 8.1 years (42 days to 32 years). The mean latency of onset of MD after the infection was 5.9 ± 4.2 weeks. The phenomenology of MD were: (1) Pure dystonia-28.6%, (2) dystonia with choreoathetosis-22.9%, (3) Parkinsonism-14.6%, (4) pure tremor, hemiballismus, myoclonus and chorea-2.9% each, and (5) mixed MD-22.9%. Most often the MD was generalized (60%), followed by right upper limb (31.4%) and left upper limb (8.6%). A viral encephalitic type of neuroinfection was the most common infection (85.7%), which was associated with MD. Abnormalities of brain MRI, seen in 79.2%, included signal changes in (1) thalamus-52.0%, (2) putamen and subcortical white matter-16% each, (3) pons-12%, (4) striatopallidum, striatum and grey matter-8% each, and (5) caudate, cerebellum, lentiform nucleus, midbrain and subthalamic nucleus-4.0% each. Conclusions: MDs associated with infection were the most often post-encephalitic. Dystonia was the most common MD, and thalamus was the most common anatomical site involved.

Abstract
West Nile virus (WNV) is an arthropod borne neurotropic single stranded RNA flavivirus with <1% developing presenting with neurological disease. Immunocompromised and elderly patients are more prone to developing WNV meningitis or encephalitis. Definitive diagnosis of WNV meningoencephalitis is a combination of clinical suspicion and cerebrospinal fluid (CSF) serology. Forty-eight year old Caucasian female presented with a sudden onset of altered mental status after being found unresponsive. She was confused with intermittent bouts of alertness/lethargy and unintelligible responses to questioning. Her medical problems included endometrial cancer that was in remission after undergoing a total abdominal hysterectomy with bilateral salpingectomy and postoperative chemotherapy with paclitaxel and carboplatin. Pertinent physical examination revealed muscle strength that was significantly decreased, nuchal rigidity and +2 pitting edema of both lower extremities. Computed tomography and magnetic resonance imaging of the brain were negative for any intracranial pathology. CSF analysis was consistent with aseptic meningitis with all CSF serology being negative except for positive WNV antibody. A few days after being admitted she developed involuntary random movements of her eyes and generalized jerking movements (myoclonus). This was determined to be opsoclonus myoclonus syndrome (OMS) induced by the WNV meningoencephalitis. She then received five consecutive days of plasmapheresis with a significant improvement in her neurological status. Opsoclonus-myoclonus syndrome (OMS) is a rare neurological disorder associated with chaotic multidirectional eye movements, myoclonus and less frequently cerebellar ataxia. OMS affects as few as 1 in 10,000,000 people per year. The pathogenesis is not fully understood with the majority of cases of opsoclonus-myoclonus syndrome being idiopathic. According to current medical literature there have only been two previous case reports of opsoclonus myoclonus syndrome associated with WNV encephalitis.

Abstract
Described in 1962, the opsoclonus-myoclonus-ataxia syndrome (OMAS) is a rare, neurologically debilitating disorder with distinct characteristics that may begin in childhood or adult life. Although many cases remain without etiological diagnosis, others are related to neoplasms and infectious diseases. We report a 41-year-old previously healthy male with an 8-day history of headache, vertigo, nausea, vomiting, and nystagmus. After a normal brain computed tomography and lymphocytic pleocytosis in cerebral spinal fluid (CSF), intravenous acyclovir therapy was initiated in the emergency room. On the third day of hospitalization, the diagnosis of OMAS was made based on the presence of chaotic and irregular eye movements, dysarthric speech, gait instability, generalized tremor, and myoclonic jerks. In the face of his neurological worsening, ampicillin followed by nonspecific immunotherapy (methylprednisolone and intravenous immunoglobulin) was prescribed, with mild clinical improvement. After a thorough laboratory workup, the definite diagnosis of neuroborreliosis was established and ceftriaxone (4 g/daily/3 wks) and doxycycline (200 mg/day/2 mo) was administered. Toward the end of the ceftriaxone regimen, the neurologic signs substantially improved. We believe this to be the first case description of OMAS as clinical presentation of Brazilian Lyme disease-like syndrome (Baggio-Yoshinari syndrome).
