Diagnostic value of 18F-fluorodeoxyglucose positron emission tomography/computed tomography imaging in pediatric opsoclonus myoclonus ataxia syndrome presenting with neuroblastoma. Pediatr Radiol 2024; 54:954-964. [PMID: 38613691 DOI: 10.1007/s00247-024-05921-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/26/2023] [Revised: 03/28/2024] [Accepted: 03/29/2024] [Indexed: 04/15/2024]
Abstract
BACKGROUND Early precision diagnosis and effective treatment of opsoclonus myoclonus ataxia syndrome (OMAS) patients presenting with neuroblastoma can prevent serious neurological outcomes. OBJECTIVE To assess the diagnostic value of 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) imaging in pediatric OMAS with neuroblastoma. MATERIALS AND METHODS A retrospective evaluation of 45 patients diagnosed with OMAS who underwent 18F-FDG PET/CT was performed. A univariate analysis was performed to compare clinical characteristics between OMAS with and without neuroblastoma. Univariate and multivariate logistic regression analyses were applied to identify independent risk factors for OMAS with neuroblastoma and to develop the clinical model. Finally, independent risk factors and PET/CT were fitted to build the combined model for the diagnosis of OMAS with neuroblastoma and presented as a nomogram. Receiver operating characteristic curve, decision curve, and calibration curve analyses were conducted to evaluate the performance of the models. RESULTS Among 45 patients, 27 were PET/CT-positive, 23/27 lesions were neuroblastoma, and four were false positives. One of the false positive patients was confirmed to be adrenal reactive hyperplasia by postoperative pathology, and the symptoms of OMAS disappeared in the remaining three cases during clinical follow-up. The average maximal standardized uptake value of PET/CT-positive lesions was 2.6. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of PET/CT were 100%, 81.8%, 85.2%, 100%, and 91.1%, respectively. Age at diagnosis, lactate dehydrogenase, and neuron-specific enolase showed statistically significant differences between OMAS with and without neuroblastoma. Lactate dehydrogenase was identified as the independent risk factor to develop the clinical model, and the clinical model demonstrated an area under the curve (AUC) of 0.82 for the diagnosis of OMAS with neuroblastoma, with an AUC as high as 0.91 when combined with PET/CT. The decision curve analysis and calibration curve demonstrated that the nomogram had good consistency and clinical usefulness. CONCLUSION In patients with OMAS, 18F-FDG PET/CT has a high diagnostic accuracy in detecting tumors of the neuroblastoma, especially when combined with the independent risk factor serum lactate dehydrogenase.

Abstract
Paraneoplastic neurological syndromes, a diverse group of neurological syndromes, are associated with small cell lung, testicular, ovarian, and breast cancers; however, their association with neuroendocrine carcinoma of the small intestine remains unreported. In this report, we present the case of a 78-year-old man diagnosed with neuroendocrine carcinoma of the small intestine and experienced symptoms such as subacute progressive numbness of the extremities and impaired gait. These symptoms were diagnosed as tumor-associated neurological syndrome. The patient had also undergone pyloric gastrectomy for early-stage gastric cancer several years prior to the appearance of the neurological symptoms. Therefore, we could not determine whether the tumor-related neurologic syndrome was owing to gastric cancer or neuroendocrine carcinoma of the small intestine; however, one of these conditions was the cause of the neuropathy. The gait disturbance and numbness relatively improved after surgery for the neuroendocrine carcinoma of the small intestine, suggesting that the neuroendocrine carcinoma of the small intestine likely caused the paraneoplastic neurological syndrome. Collectively, we present a unique report highlighting the putative relationship between small bowel neuroendocrine carcinoma and tumor-associated neurologic syndromes.

Abstract
Opsoclonus myoclonus syndrome (OMS) is a rare (1 in 10 million people per year) but nonfatal autoimmune disorder characterized by involuntary oscillating eye movements, multifocal muscular jerky movements, severe ataxia, and neuropsychological and behavioral changes. It usually manifests as a paraneoplastic condition but has other etiologies also. To the best of our knowledge, this is the first case of OMS seen in a patient with severe acute malnutrition (SAM). Parents brought a three-year-old female child with complaints of being unable to sit, stand, and hold her neck for the past 18 months. The patient has had involuntary eyeball movements for three months and has shown regression in milestones. Our study aimed to understand the pathophysiology, etiology, and clinical course of OMS in a child with SAM. However, relapses and long-term developmental sequelae are common due to the lack of a common consensus regarding therapeutic guidelines.

Monocentric retrospective clinical outcome in a group of 13 patients with opsoclonus myoclonus syndrome, proposal of diagnostic algorithm and review of the literature. Eur J Paediatr Neurol 2022; 40:18-27. [PMID: 35926472 DOI: 10.1016/j.ejpn.2022.07.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/18/2021] [Revised: 06/26/2022] [Accepted: 07/04/2022] [Indexed: 11/20/2022]
Abstract
BACKGROUND Dancing eye syndrome or opsoclonus-myoclonus syndrome (OMS) is a very rare disease (incidence <1/5,000,000 per year), which is more prevalent in young children. Although it is not usually a cause of mortality, the aftermaths are not rare. METHODS We performed an observational retrospective review of children diagnosed with OMS in our neuropediatric department from 1996 to 2020, with the objective of assessing the prognostic value of initial clinical features. All medical data from diagnosis to last follow-up were reviewed. We defined unfavorable evolution of OMS as persistence or worsening of symptoms. Subsequently, based on a literature review, our results and experience, a diagnostic algorithm was developed. RESULTS A total of 13 OMS patients were included: 61.5% were male (n = 8), median age at diagnosis was 18 months (IR = 76), median treatment delay was 14 days (IR = 146) and OMS score at onset was 8 (IR = 11). The most frequent etiologies were neuroblastoma-associated and idiopathic OMS (38.46%; n = 5) of the patients, followed by post-infectious OMS (n = 3). All the patients were treated with corticosteroids, five required a surgical intervention (neuroblastoma group), and three required adjunctive immune therapy (immunoglobulins, cyclophosphamide and/or rituximab). We detected neurodevelopmental disorders in 38.46% (n = 5) of the patients, mainly attention deficit (n = 4), and persistent sleep disturbances (n = 4). The median OMS score at the end of follow-up was 1 (IR = 3). An important diagnostic delay, OMS score of ≥10 and age >1 year at onset may correlate with a higher risk of aftermaths. We detected a better prognosis in the post-infectious OMS, with full recovery occurring in 2/3 of patients. CONCLUSIONS Early clinical suspicion is key to guarantee maximum response of treatment.

Abstract
BACKGROUND Neuroblastoma with opsoclonus-myoclonus syndrome (OMS-NB) is a rare disease in children. Few studies of long-term outcome of children with OMS-NB were conducted. This study aimed to review the rate of recovery of neurological symptoms and the long-term neurological outcomes of children with OMS-NB. METHODS This study retrospectively assessed 14 children with OMS-NB diagnosed at Peking University First Hospital from May 2011 to November 2019. Demographic data, neurological symptoms, oncological status and treatments were retrospectively reviewed from the records. Neurological sequelae were recorded by clinical and remote follow-up. RESULTS During the acute stage, myoclonus and ataxia were observed in all children while opsoclonus was observed in 10/14 children. The median durations of neurological symptoms were 15 months (range, 5-48 months). Approximately 93% (13/14) children revealed neurological sequelae. Significant correlations were as follows: motor retardation with female gender (P<0.001) and residual tumors (P<0.05); language impairment with non-adrenal-gland-located tumors (P<0.05). There were no obvious factors that had a statistical relationship with cognitive disorder or behavioral changes. CONCLUSIONS Children with OMS-NB have favorable outcomes in terms of neurological symptoms. Neurological sequelae occurred in almost all children. Children with different features tend to reveal different sequalae. Features of female gender and residual tumors tend to reveal motor retardation while that of non-adrenal-gland-located tumors tend to reveal language impairment.

Abstract
Opsoclonus-myoclonus syndrome (OMS) is a neurological non-fatal disease that usually responds to immunotherapies. However, the real challenge is to counteract the high frequency of relapses and long-term developmental sequelae. Since the OMS is extremely rare, a common consensus regarding therapeutic guidelines is still lacking. The goals of this study were to test whether ACTH was superior to other immunotherapies and to investigate whether an early treatment could improve the outcome. Sixteen children affected by OMS were retrospectively reviewed. Eight children had a neuroblastic tumor. The other eight patients were affected by non-paraneoplastic OMS. Overall, the most commonly used treatment was corticotherapy (n = 11). However, ACTH (n = 10), rituximab (n = 7), immunoglobulins (n = 4), cyclophosphamide (n = 3), and mycophenolate (n = 2) were also administered. ACTH was associated with a high percentage of patients who healed (80%) and, as a first-line therapy, was associated with a lower incidence of relapses. An early treatment was associated with a favorable long-term outcome. Long-term sequelae occurred in 42% of patients who were treated early and in all of those who were treated late. It is advisable for the affected children to be identified at an early time, as they may benefit from an early treatment. ACTH represents an effective treatment with a high probability of recovery and low rate of relapses.

Abstract
AIM To determine predictors of full-scale IQ (FSIQ) in an international pediatric opsoclonus myoclonus syndrome (OMS) cohort. METHOD In this retrospective and prospective cohort study at three academic medical centers (2006-2013), the primary outcome measure, FSIQ, was categorized based on z-score: above average (≥+1), average (+1 to -1), mildly impaired (-1 to -2), and impaired (<-2). Univariate analysis and multivariable linear regression modeling using stepwise selection with Akaike's information criterion was performed to understand the relationship between exposures and FSIQ. RESULTS Of 81 participants, 37 with sufficient data had mean FSIQ 84.38 (SD 20.55) and median 90 (40-114) at latest available evaluation (mean age 8y 5mo). Twenty (54%), nine (24.3%), and eight (21.6%) had normal, mildly impaired, and impaired FSIQ respectively. The final multivariable linear regression model included 34 participants with evaluable data: number of relapses occurring before neuropsychological testing (p<0.001) and OMS severity score at last follow-up (p<0.001) predicted FSIQ (adjusted R2 =0.64). There was a mean decrease of 2.4 FSIQ points per OMS relapse. INTERPRETATION Number of relapses negatively correlates with FSIQ in pediatric OMS. Demographic and clinical measures available at OMS onset did not predict FSIQ. Strategies to reduce OMS relapses may improve intellectual outcomes.

Abstract
Opsoclonus myoclonus syndrome (OMS) is a rare neurological syndrome caused by a paraneoplastic autoimmune process that affects children with neuroblastic tumors. Treatment includes corticosteroids, intravenous gamma globulin (IVIG), rituximab, and other immunosuppressive therapies. Here, we describe a patient diagnosed with OMS associated with a localized inflammatory myofibroblastic tumor. The patient has no evidence of tumor recurrence following surgical resection with 8-month follow-up. The neurologic symptoms resolved with corticosteroids and IVIG. This case demonstrates that in children, neoplasms other than neuroblastoma may be associated with this paraneoplastic syndrome, and highlights the importance of evaluating patients with OMS for underlying malignancies.

Abstract
INTRODUCTION Flow cytometric cerebrospinal fluid (CSF) lymphocyte subset analysis has improved the diagnosis of neuroinflammation and identified multiple markers of inflammation in opsoclonus-myoclonus syndrome (OMS). The aim of this exploratory, retrospective study was to analyze the effect of immunotherapy on these markers to determine which agents are disease modifying. METHODS Cross-sectional immunological observations were made in an IRB-approved case-control study, and patients were treated empirically. Ten different CSF lymphocyte subpopulations from 18 children with persistent OMS had been measured by flow cytometry before and after clinical treatment with cyclophosphamide/ACTH/IVIG combination (n = 7) or ACTH/IVIG alone (n = 11). Clinical severity of OMS was scored from videotapes by a blinded observer using the OMS Evaluation Scale. RESULTS Only cyclophosphamide combination therapy (mean dose 26 ± 3 mg/kg or 922 ± 176 mg/m2 x 6 cycles) significantly decreased the percentage of CSF B cells. The mean reduction was 65%, with CSF B cell frequency normalized at 7-8 months in 70%. Other abnormalities of the CSF immunophenotype, such as the low CD4/CD8 T cell ratio, persisted, and there were no therapeutic changes in T cell activation/maturation markers. Effects on relative and absolute size of PBMC subsets were similar. Clinical improvement was 70% and 55% in respective treatment groups. The relapse rates of the two groups did not significantly differ. DISCUSSION The main effect of cyclophosphamide combination therapy on neuroinflammation in OMS was moderate reduction in CSF B cell expansion. Though exploratory, it may provide a steroid sparer option in partially-responsive OMS.

Abstract
We evaluated the frequency of serum antineuronal antibodies in a cohort of 39 neuroblastoma patients and related their presence to clinical features. Twelve patients displayed antineuronal antibodies at immunocytochemistry. Only one of these 12 patients suffered from a clinically overt paraneoplastic syndrome. No significant differences emerged between autoantibody-positive and autoantibody-negative patients in terms of progression-free and overall survival, although when only patients evolving to disease progression were considered, the time interval between diagnosis and progression was slightly longer in autoantibody-positive patients.

Abstract
Opsoclonus-myoclonus syndrome (OMS) is a rare, autoimmune neurological disorder that is poorly recognized and undertreated. Neuroblastoma is found in one half of the cases. Because of the high incidence of spontaneous regression of neuroblastoma, it is unknown whether not finding a tumor means there was none. To define demographic trends and the standard of care in the first large series of OMS, 105 children were recruited over a 13-year period in a retrospective questionnaire survey. Children with and without a tumor differed little in viral-like prodrome and neurological symptoms. Earliest neurological symptoms were staggering and falling, leading to a misdiagnosis of acute cerebellitis. Later symptoms included body jerks, drooling, refusal to walk or sit, speech problems, decreased muscle tone, opsoclonus, and inability to sleep. Tumor resection alone did not provide adequate therapy for most. Adrenocorticotropic hormone (ACTH), prednisone, and intravenous immunoglobulin were used with equal frequency, but ACTH was associated with the best early response. More than one half of the children had relapses. Residual behavioral, language, and cognitive problems occurred in the majority. The delay in diagnosis (11 weeks) and initiation of treatment (17 weeks) is unacceptably long.

Abstract
Despite advances in inducing remission in pediatric opsoclonus-myoclonus syndrome (OMS), relapse remains a challenge. By definition, relapse is not a characteristic of monophasic OMS, but occurs at any time in the course of multiphasic OMS. Due to variability and heterogeneity, patients are best approached and treated on a case-by-case basis, using precepts derived from clinical and scientific studies. Treatment of provocations, such as infection or immunotherapy tapering, is the short-term goal, but discovering unresolved neuroinflammation and re-configuring disease-modifying agents is crucial in the long-term. The working hypothesis is that much of the injury in OMS results from neuroinflammation involving dysregulated B cells, which may cause loss of tolerance and autoantibody production. Biomarkers of disease activity include cerebrospinal fluid (CSF) B cell frequency, oligoclonal bands (OCB), B cell attractants (CXCL13) and activating factors (BAFF). Measuring these markers comprises modern detection and characterization of neuroinflammation or verifies 'no evidence of disease activity'. The decision making process is three-tiered: deciding if the relapse is bone fide, identifying its etiology, and formulating a therapeutic plan. Relapsing-remitting OMS is treatable, and combination multimodal/multi-mechanistic immunotherapy is improving the outcome. However, some patients progress to a refractory state with cognitive impairment and disability from failure to go into remission, multiple relapses, or more aggressive disease. This report provides new insights on underappreciated risks and pitfalls inherent in relapse, pro-active efforts to avoid progression, the need for early and sufficient treatment beyond corticosteroids and immunoglobulins, and utilization of disease activity biomarkers to identify high-risk patients and safely withdraw immunotherapy.

Abstract
Tumor vaccines have held much promise, but to date have demonstrated little clinical success. This lack of success is conceivably due to poor tumor antigen presentation combined with immuno-suppressive mechanisms exploited by the tumor itself. Knock down of Inhibitor of differentiation protein 2 (Id2-kd) in mouse neuroblastoma whole tumor cells rendered these cells immunogenic. Id2-kd neuroblastoma (Neuro2a) cells (Id2-kd N2a) failed to grow in most immune competent mice and these mice subsequently developed immunity against further wild-type Neuro2a tumor cell challenge. Id2-kd N2a cells grew aggressively in immune-compromised hosts, thereby establishing the immunogenicity of these cells. Therapeutic vaccination with Id2-kd N2a cells alone suppressed tumor growth even in established neuroblastoma tumors and when used in combination with immune checkpoint blockade eradicated large established tumors. Mechanistically, immune cell depletion studies demonstrated that while CD8+ T cells are critical for antitumor immunity, CD4+ T cells are also required to induce a sustained long-lasting helper effect. An increase in number of CD8+ T-cells and enhanced production of interferon gamma (IFNγ) was observed in tumor antigen stimulated splenocytes of vaccinated mice. More importantly, a massive influx of cytotoxic CD8+ T-cells infiltrated the shrinking tumor following combined immunotherapy. These findings show that down regulation of Id2 induced tumor cell immunity and in combination with checkpoint blockade produced a novel, potent, T-cell mediated tumor vaccine strategy.

Abstract
To test the efficacy and safety of corticotropin-based immunotherapies in pediatric opsoclonus-myoclonus syndrome, 74 children received corticotropin alone or with intravenous immunoglobulin (groups 1 and 2, active controls); or both with rituximab (group 3) or cyclophosphamide (group 4); or with rituximab plus chemotherapy (group 5) or steroid sparers (group 6). There was 65% improvement in motor severity score across groups (P < .0001), but treatment combinations were more effective than corticotropin alone (P = .0009). Groups 3, 4, and 5 responded better than group 1; groups 3 and 5 responded better than group 2. The response frequency to corticotropin was higher than to prior corticosteroids (P < .0001). Fifty-five percent had adverse events (corticosteroid excess), more so with multiagents (P = .03); and 10% had serious adverse events. This study demonstrates greater efficacy of corticotropin-based multimodal therapy compared with conventional therapy, greater response to corticotropin than corticosteroid-based therapy, and overall tolerability.

Abstract
AIM The cognitive and psychiatric aspects of adult movement disorders are well established, but specific behavioural profiles for paediatric movement disorders have not been delineated. Knowledge of non-motor phenotypes may guide treatment and determine which symptoms are suggestive of a specific movement disorder and which indicate medication effects. METHOD The goal of this review is to outline the known cognitive and psychiatric symptoms associated with paediatric movement disorders. We used a systematic approach, via PubMed, and reviewed over 400 abstracts of studies of selected disorders, of which 88 papers reporting paediatric non-motor symptoms are summarized. RESULTS Obsessive-compulsive disorder was manifest in children with paediatric autoimmune neuropsychiatric disorders associated with streptococcal infections and Sydenham chorea. Children with opsoclonus-myoclonus syndrome had, for the most part, cognitive and behavioural problems, and attention-deficit-hyperactivity disorder was reported as a major comorbidity in Tourette syndrome, stereotypies, and restless legs syndrome. Symptoms of depression and anxiety were more frequent in individuals with idiopathic dystonia. Affective disorders were suggestive of Wilson disease. Cognitive decline was common in children with juvenile Huntington disease. A limitation of this review was the lack of systematic assessment in paediatric movement disorders for evaluation and uniform definitions. INTERPRETATION Although the literature in non-motor phenomena is still emerging, recognition of salient cognitive and psychiatric phenomena may facilitate management of paediatric movement disorders.

Abstract
OBJECTIVE Opsoclonus-myoclonus syndrome (OMS) is a serious and often chronically disabling neurologic illness with onset in early childhood. Our aim was to identify long-term neurologic sequelae of OMS and predictors for disease outcome. METHODS We retrospectively assessed the case records of 101 patients diagnosed with OMS over a 53-year period. Clinical data were obtained from medical record review; we documented age at onset, severity of symptoms, response to treatment, and neurocognitive sequelae. RESULTS Overall, 21% of the patients had a neuroblastoma detected; however, in those born after 1990, this figure rose to 40%. Sixty-one percent of the patients had a chronic-relapsing course, 32% experienced several acute exacerbations, and 7% had a monophasic course. At the most recent review, 60% had residual motor problems, 66% speech abnormalities, 51% learning disability, and 46% behavior problems. One-third of the patients had normal intellectual outcome and cessation of symptoms. A severe initial presentation predicted a chronic disease course (odds ratio [OR]: 2.77 [95% confidence interval (CI): 1.47-5.23]; P = .002) and later learning disability (OR: 2.03 [95% CI: 1.08-3.79]; P = .026). Those with cognitive impairment were younger at disease onset (15.0 vs 19.5 months; P = .029). A chronic-relapsing disease course was associated with motor (P < .001), speech (P = .001), cognitive (P < .001), and behavior (P = .006) problems. CONCLUSIONS OMS is a chronic and debilitating illness; those with severe initial symptoms and those who are very young at disease onset are at increased risk of developing long-term sequelae. It is important for affected children to be identified early, because they might benefit from targeted immunomodulating therapy in specialist centers.

Abstract
We review current concepts of nystagmus and saccadic oscillations, applying a pathophysiological approach. We begin by discussing how nystagmus may arise when the mechanisms that normally hold gaze steady are impaired. We then describe the clinical and laboratory evaluation of patients with ocular oscillations. Next, we systematically review the features of nystagmus arising from peripheral and central vestibular disorders, nystagmus due to an abnormal gaze-holding mechanism (neural integrator), and nystagmus occurring when vision is compromised. We then discuss forms of nystagmus for which the pathogenesis is not well understood, including acquired pendular nystagmus and congenital forms of nystagmus. We then summarize the spectrum of saccadic disorders that disrupt steady gaze, from intrusions to flutter and opsoclonus. Finally, we review current treatment options for nystagmus and saccadic oscillations, including drugs, surgery, and optical methods. Examples of each type of nystagmus are provided in the form of figures.

Abstract
PURPOSE OF REVIEW Opsoclonus-myoclonus-ataxia syndrome (OMS) is a severe autoimmune central nervous system disorder, which predominantly affects young children and causes lifelong neurological disability. Early recognition and treatment may yield better outcomes. RECENT FINDINGS Appreciation of the spectrum of clinical presentations of OMS, awareness of common misdiagnoses, and utilization of diagnostic criteria may facilitate the timely diagnosis of OMS. Approximately 50% of patients have an associated neuroblastoma, which may escape detection by traditional methods and require MRI or computed tomography of the torso for diagnosis. In nonparaneoplastic cases, many associated infections have been reported. Although there has been progress in autoantibody identification and cerebrospinal fluid B cell expansion is a common finding, there is no diagnostic biomarker for OMS currently. Approximately 80% of reported patients, typically treated with conventional therapies such as adrenocorticotropin hormone, corticosteroids, and/or intravenous immunoglobulin, develop long-term neurological morbidity. Newer treatment approaches using early, aggressive therapy with cyclophosphamide or rituximab are promising. SUMMARY The diagnosis of OMS requires a high level of suspicion and a systematic approach for diagnostic testing, particularly for neuroblastoma. Future collaborative studies are required to determine whether early, aggressive therapy will improve the typically poor long-term neurological outcome.

Abstract
OBJECTIVE To compare the clinical data at diagnosis, treatment and neurological outcome in 34 children with opsoclonus-myoclonus syndrome (OMS) associated with a detected neuroblastoma or not. STUDY DESIGN This is a multicentric retrospective study of 34 children presenting with OMS from four pediatric centers diagnosed between 1988 and 2008. RESULTS Twenty-two patients had OMS associated with a neuroblastoma. These patients all had neuroblastomas with favourable prognostic features; all underwent surgery, six received chemotherapy. Twelve children had OMS without a detected neuroblastoma. For OMS, the main treatment in all children was corticotherapy (n=33), but immunoglobulins (n=13), cyclophosphamide (n=4) and rituximab (n=4) were also given. In the 27 OMS patients with or without neuroblastoma whose follow up was greater than two years, the neurological outcome was evaluated: 59.3% had neurological sequelae, including motor, praxic and/or language sequelae (n=9), persistent ataxia (n=6) and moderate motor deficit (n=3). No significant difference in neurological outcome was noted between the two patient groups. CONCLUSION Our retrospective study provides further evidence that OMS with or without a detected neuroblastoma is the same disease, whose major challenges are the neurological sequelae. An international collaboration is required to improve the knowledge about OMS, the treatment and the outcome in this rare disorder.

Abstract
The incidence, mode of presentation and management of Dancing Eye Syndrome/Opsoclonus-Myoclonus Syndrome (DES/OMS) was prospectively evaluated in 20 United Kingdom (UK) paediatric neurology centres by questionnaire over a 24-month period between 2003 and 2005. Nineteen children were notified, giving an incidence of 0.18 cases per million total population per year. Mean age at presentation was 18 months (range 3-42 months). Fifteen families consented to participate in the study. Atypical features were present in 6/15 cases including very delayed presentation of opsoclonus, dysphagia, and rapid spontaneous improvement without treatment. Only 4/15 cases were associated with neuroblastoma (NB) but current practice in excluding this is diverse and a standardised approach is suggested.

Abstract
BACKGROUND Kinsbourne syndrome or opsoclonus myoclonus syndrome (OMS) is characterized by rapid, involuntary, irregular conjugate eye movements (opsoclonus), myoclonic jerking of the limbs and trunk, ataxia, and behavioral disturbances. In general, the outcome of neurologic and behavioral symptoms is poor. Studies on quality of life (Qol) and recovery after very long-term follow-up of children with OMS are lacking. METHODS We studied long-term cancer survival, neurologic recovery, and Qol of a consecutive series of eight patients with OMS that were treated in our center. Two cross-sectional follow-up evaluations were conducted at a 3-year interval (T1 and T2). RESULTS In four out of eight children with OMS a neuroblastoma (NBL) was diagnosed and surgically removed completely. All children received immuno-modulatory therapy, consisting of prednisone (three children), prednisone and ACTH (four children), or prednisone, ACTH, and gammaglobulin (one child). At T1, median follow-up time was 9.5 years (range 3-14 years) after OMS onset and at T2, 11.6 years (range 6-17 years). Neurologic functioning improved in all children, reflected by a significant improvement of the mean Z-score in the motor domain of the Qol questionnaire at T2 as compared to T1. In contrast, seven children continued to have a severe developmental delay at T2. No significant difference in any of the variables was found between NBL survivors and OMS patients without NBL. CONCLUSION Cognitive and behavioral impairments and not a motor impairment, such as ataxia, appear to be predominant at long-term in children with OMS.

Abstract
Opsoclonus-myoclonus-ataxia-syndrome (OMS) represents a rare neuroblastoma-associated paraneoplastic syndrome that commonly results in neurologic deficits despite tumor resection and immunosuppressive therapy. We describe the response of five such children to high-dose dexamethasone pulses including two patients in whom previous glucocorticoids, rituximab, and cytostatic drugs were not successful. All patients had MYCN non-amplified tumors that were detected 1 to 7 months after the onset of the OMS or ataxia. This treatment resulted in a good partial response in three and in complete remission in two patients. Our results show that dexamethasone pulses are likely to be useful for both, first-line- and salvage-therapy for OMS-patients.

Abstract
Opsoclonus-myoclonus syndrome (OMS) is a rare paraneoplastic syndrome that occurs in 2%-3% of patients with neuroblastoma. The cause of this syndrome is believed to be immune mediated, but the exact mechanism still remains unclear. There is an urgent need to improve our current strategies for treating patients with OMS, as many patients have significant long-term neurologic deficits and behavior disorders with current treatment approaches. Therapies that have shown to improve symptoms in these patients have ranged from ACTH and corticosteroids, to intravenous gammaglobulin and plasmapheresis. We report our experience with Rituximab in a patient with neuroblastoma and OMS.

Abstract
Opsoclonus-myoclonus syndrome (OMS) is a rare and debilitating disorder of unknown etiology affecting children and adults. Outcome is unfavourable; approximately 80% of children with OMS suffer from mild to severe neurological handicaps, mainly cognitive impairment. A standard therapy does not exist. Due to the possible immune-mediated mechanisms, treatment with steroids, ACTH, plasmapheresis and immunoglobulins can be successful. However, some children become steroid dependent and symptoms may reoccur after treatment has been finished. We present two girls with OMS, who had a prolonged clinical course lasting 4 and 9 years with many relapses. Both children developed symptoms around the age of two years. Diagnostic work-up to exclude neuroblastoma was negative. Several treatment modalities including oral steroids, dexamethasone pulses, immunoglobulin and cyclosporine were used without lasting success. In addition, cognitive impairment developed in both children. In order to prevent further clinical and mental deterioration, 6 pulses of cyclophosphamide in combination with dexamethasone pulses every 4 weeks were administered. Both children showed significant improvement of OMS symptoms. One girl is still symptom free 18 months after treatment, mild ataxia developed in the other after 12 months. Both children are mentally handicapped and in special need schools. We conclude that combination of cyclophosphamide pulses and dexamethasone pulse therapy is a therapeutic option even after a long clinical course to improve symptoms of OMS.

Abstract
UNLABELLED Mycoplasma pneumoniae infection is associated with various manifestations involving the central nervous system but it has never been reported as a potential aetiology of opsoclonus-myoclonus syndrome (OMS) in children. OBSERVATION We report on a case in a 4-year-old girl who presented neurological manifestations compatible with an OMS, after a respiratory tract disease. Aetiological investigations revealed M. pneumoniae infection as specific IgM were present in the serum (Elisa). Evolution after corticosteroid, intravenous immunoglobulins and macrolide therapy was favourable as clinical symptoms disappeared. After a 12-month follow-up, the patient has no neurological sequela. CONCLUSION M. pneumoniae infection should be added to the list of causes to be screened in OMS. Its pathophysiology remains unknown but may involve a dysimmune postinfectious mechanism.

Abstract
Opsoclonus-myoclonus syndrome (OMS) in children is a rare neurological condition with opsoclonus, myoclonus, ataxia and irritability in the first 2 years of life. It can be idiopathic, parainfectious, or paraneoplastic with tumours of the neural crest. Few studies of long-term follow-up after OMS have been published. We investigated the motor, cognitive and behavioural outcome of ten patients (eight girls and two boys) seen between 1987 and 2002. We reviewed the records and reassessed the patients. A ganglioneuroma was found in one patient and a neuroblastoma in another. Tumour resection did not influence the OMS. The age at diagnosis was 10-24 months and the follow-up period 1-17 years (average 6.5 years). The interval between the first signs and symptoms and starting treatment was 2-12 weeks: treatment consisted of different immunosupressants. Remission was achieved within 5 months in seven, and relapses were present in seven of ten. At follow-up, only one child had mild ataxia. IQ testing was performed in nine with scores below 75 in four and above 85 in four. Attention deficit and visuomotor difficulties led to school problems with special needs, also in those three children with normal IQs. Only two children were attending regular schools. Behavioural problems were reported in seven, and speech difficulties were present in five. In conclusion, the long-term outcome in our patients with OMS was dominated by cognitive and behavioural problems and not by ataxia. Compared with previous reports, our patients were treated earlier. Larger studies and uniform treatment protocols are needed to demonstrate whether early and prolonged immunosupressant therapy has a favourable influence on outcome.

Abstract
We describe the case of a 2-year-old girl with opsoclonus-myoclonus syndrome treated with chronic adrenocorticotropic hormone (ACTH) in which a metaiodobenzylguanidine scan showed abnormal radiotracer uptake in the left adrenal gland region, interpreted as the site of an occult neuroblastoma. As this finding was not corroborated by previous or subsequent metaiodobenzylguanidine scans or by computed tomography (CT) or magnetic resonance imaging (MRI), we attribute the finding to being a false-positive result from adrenal hyperplasia owing to chronic use of ACTH and not to neuroblastoma. Metaiodobenzylguanidine scintigraphy is an extremely important nuclear medicine examination tool used for the evaluation and staging of pediatric neuroblastoma. We highlight the need for cautious interpretation of metaiodobenzylguanidine as a screening tool for neuroblastoma in patients treated with ACTH.

Abstract
OBJECTIVE We previously reported on children with opsoclonus-ataxia and found pervasive neurodevelopmental deficits, years after onset, without a clear relationship to treatment modality or timing of treatment. A significant negative correlation of functional status with age at testing raised a question of whether opsoclonus-ataxia is a progressive encephalopathy. We attempted to answer this question with serial testing. In addition, we examined the relationship between clinical course and developmental outcome. METHODS Thirteen of 17 children with opsoclonus-ataxia, all with neuroblastoma, who were previously reported were reevaluated a second time 2 to 4 years after the initial assessment. One subject who lived out of state was partially reevaluated and is included. Five new subjects (2 with neuroblastoma and 3 without) were also enrolled. Each was evaluated twice at a minimum interval of 1 year between sessions. Intercurrent medical course was recorded, emphasizing medication and relapse history. Cognitive, adaptive behavior, academic, speech and language, and motor abilities were assessed. RESULTS For the group as a whole, overall standardized, age-adjusted cognitive scores improved. Generally, younger subjects' cognitive and adaptive behavior scores improved more than older subjects. Although all subjects had gains in speech, language, and motor function, some progressed at a slow pace, and in some instances, standard scores dropped. There was a striking influence of clinical course. Although initial presentation was severe and all subjects required high doses of corticosteroids or corticotropin, 5 had a monophasic course and were able to be weaned from treatment without relapses. Fourteen had multiple relapses over the years, generally with reduction of medication or intercurrent illnesses. Of the 5 children with monophasic course, 4 are currently functioning in the average range with a full-scale IQ of > or =90 and age-appropriate academic and adaptive skills. CONCLUSIONS The results continue to raise concern that opsoclonus-ataxia is sometimes a progressive encephalopathy. A minority of children with opsoclonus-ataxia have a monophasic course. Despite initial severity of symptoms, these children may have a more benign prognosis. For the majority of children with opsoclonus-ataxia, the course includes multiple relapses and requires prolonged treatment. Developmental sequelae are significant in these children with chronic course.

Abstract
Opsoclonus-myoclonus syndrome (OMS) is a rare neurologic syndrome that, in children, associates with neuroblastoma in more than half of the cases. The etiology of this condition is thought to be immune mediated, but, though immunosuppressive therapies may ameliorate the acute symptoms, no effective treatment to prevent the common neuropsychologic sequelae has been established. This paper summarizes the results obtained at the 2004 Advances in Neuroblastoma Research meeting, providing status of the art information on immune pathogenesis, clinical features, acute and chronic neurologic manifestations, current and novel therapeutic approaches. It is emphasized that, due to the rarity of OMS in general and neuroblastoma-associated OMS in particular, international collaborations are needed to better define the pathogenesis and therapy of this disease, propose common evaluation criteria and identify new treatment modalities.

Abstract
Opsoclonus-myoclonus-ataxia syndrome (OMA) in children is most commonly associated with occult neuroblastoma (NB). Although children with OMA and NB have decreased mortality, they suffer from increased neurologic morbidity. The pathogenesis of OMA in NB is not well understood, but current research and treatments support an immune-mediated process. The authors describe an unusual presentation of OMA occurring following 6 months of chemotherapy in a child with stage 4S NB who presented with partial Horner syndrome. Histopathologic examination of his primary cervical tumor showed NB maturation, which may have played a role in precipitating OMA syndrome. Further study of unusual cases of OMA in NB may provide better understanding of the syndrome and additional treatment options for these children.

Abstract
The present review is aimed at providing practical assistance to the clinical neurologist in reaching a diagnosis, understanding the pathogenic mechanisms of movement disorders associated with systemic diseases, and determining appropriate therapy. Infectious disease by direct effect or as an acquired autoimmune neurological disease, stroke, hypoxia-ischemia, paraneoplastic syndromes, collagen disorders, endocrine, liver and kidney diseases that may cause hypokinetic or hyperkinetic abnormal movement are considered separately. The type and evolution of abnormal movement caused by systemic disease vary with age and underlying pathology. Therapy for abnormal movements should include a primary treatment for the systemic disease.

Abstract
Neuroblastoma, a common tumor of neural crest origin, demonstrates an extremely variable clinical presentation and behavior. Paraspinal tumors may occur anywhere along the spinal column where they may invade the intervertebral foramina and produce cord compression. Cervical involvement may produce Horner's syndrome. Opsoclonus-myoclonus syndrome is also a well-known neuroimmunologic finding of neuroblastoma. We report a 28-month-old female presenting with ptosis and muscle weakness, diagnosed as having a neuroblastoma.

Abstract
Neuroblastoma, a childhood neoplasm arising from neural crest cells, is characterized by a diversity of clinical behavior ranging from spontaneous remission to rapid tumor progression and death. To a large extent, outcome can be predicted by the stage of disease and the age at diagnosis. However, the molecular events responsible for the variability in response to treatment and the rate of tumor growth remain largely unknown. Over the past decade, transformation-linked genetic changes have been identified in neuroblastoma tumors that have contributed to the understanding of tumor predisposition, metastasis, treatment responsiveness, and prognosis. The Children's Oncology Group recently developed a Neuroblastoma Risk Stratification System that is currently in use for treatment stratification purposes, based on clinical and biologic factors that are strongly predictive of outcome. This review discusses the current risk-based treatment approaches for children with neuroblastoma and recent advances in biologic therapy.

Abstract
A7-month-old girl was referred by her GP with a 6-hour history of ‘jittery eyes’. During the preceding day she had been ‘grizzly’ and non-specifically unwell. Her mother reported that on the day of admission she had had rigors and abnormal eye movements. The child had no significant past medical history. There was a family history of epilepsy. Paediatric review noted a miserable child with an inflamed right tympanic membrane and sudden eye movements up and to the right. An electroencephalogram was performed which was normal and a provisional diagnosis was made of right-sided otitis media with associated nystagmus resulting from putative labyrinthine involvement. The child was started on a course of amoxycillin and admitted. After 24 hours her condition had improved and she was discharged, pending an ophthalmology review 4 days later. At the ophthalmology review it was noted that although the child appeared generally well, she was distressed by recurrent sudden conjugate dextro-elevatory eye movements associated with simultaneous backward jerks of the head. She was ataxic but the examination was otherwise normal. The opinion of a paediatric ophthalmologist was sought, the diagnosis of opsoclonus was made and further investigation arranged. Chest radiography revealed bilateral paravertebral mass in the lower thoracic region (Figure 1). Magnetic resonance imaging confirmed this and showed anterior extension encircling the aorta and displacing the inferior vena cava (Figure 2). Considerable enhancement with gadolinium was noted. No involvement of liver, spleen or cranium was seen. A bone scan and marrow trephine was normal. An MIBG (metaiodobenzyl guanidine) scan showed increased uptake in the lower thoracic right paraspinal area. Tumour biopsy revealed rosettes of small round cells consistent with neuroblastoma. The diagnosis was therefore of thoraco-abdominal neuroblastoma stage 3. This was not resectable and chemotherapy was started as per the European Infant Neuroblastoma Protocol. She made rapid improvement with radiographic reduction in tumour size and dramatic improvement in her neurological features.

Abstract
The aim of this study was to investigate the histological, immunohistochemical and molecular features of a series of children with neuroblastic tumors (NTs) and opsoclonus-myoclonus syndrome (OMS). Of 1187 children (age 0-15 years) with previously untreated NTs registered between 1979 and 1995, 15 (1.3%) had OMS at presentation. The majority of patients showed favorable biological characteristics, such as lack of amplification of the neuroblastoma-associated avian myelocytomatosis homolog MYCN oncogene and aneuploid nuclear DNA content. Tumor histology was reviewed according to the International Neuroblastoma Pathology Classification. Histology of the 15 cases of NTs with OMS was ganglioneuroblastoma, intermixed, in 10 patients; ganglioneuroma, maturing, in 1; and neuroblastoma in 4. Of 15 tumors, 12 (10 ganglioneuroblastomas, 2 neuroblastomas) showed abundant interstitial or perivascular lymphoid infiltrates, the latter often organized in secondary lymphoid follicles. The three remaining cases had only minimal infiltrates. A review of 91 cases of age- and stage-matched neuroblastic tumors not associated with OMS tested as controls showed that the degree of lymphoid infiltration was significantly lower than that detected in OMS-related tumors. Furthermore, lymphoid follicles were always present in the latter tumors, whereas they were detected only in a few ganglioneuroma, intermixed tumors from the control group. In conclusion, ganglioneuroblastoma, intermixed subtype, lack of MYCN amplification, aneuploid DNA content and presence of lymphoid infiltrates may contribute to favorable prognosis in NTs associated with OMS.

Abstract
Acute childhood ataxia is a common cause of presentation to the pediatric emergency room or child neurologist. The primary concern on initial assessment is to exclude serious causes of this clinical syndrome, including central nervous system infections and mass lesions, while recognizing the essentially benign nature of acute ataxia in most children. Childhood ataxia can be diagnostically approached by consideration of the temporal course and presence or absence of associated neurologic abnormalities. In all forms of childhood ataxia, outcome is largely determined by etiology. In this review, the various causes and syndromes of acute ataxia in childhood are described, with discussion of diagnostic considerations and an approach to investigation, treatment, and prognosis.

Abstract
Cancer can affect the nervous system through many metastatic and nonmetastatic mechanisms, including side effects of cancer treatment, infections, coagulopathy, and metabolic or nutritional deficits. Paraneoplastic neurologic disorders (PND) are an extensive group of syndromes that cannot be explained by any of these complications and may affect any part of the nervous system. PND often develop before the presence of a cancer is known and their recognition may lead to the tumor diagnosis.

Abstract
Paraneoplastic neurologic syndromes (PNS) comprise an extensive group of heterogeneous disorders that can affect any part of the central and peripheral nervous system. There is evidence that many of these disorders are mediated by immunologic responses triggered by the presence of a cancer. Several immunologic mechanisms and many antigenic targets have been related to these disorders. Some disorders of the neuromuscular junction or peripheral nervous system are directly mediated by antibodies, and they may have a paraneoplastic origin or develop without a tumor association. For these disorders and a few PNS of the central nervous system, immunotherapy may result in neurologic improvement. However, for most PNS of the peripheral and central nervous system the response to any type of therapy is, in general, disappointing. The main concern of the clinician should be to rule out other diagnostic entities and to uncover the presence of the associated neoplasm that often remains elusive to detection. In general, the best approach to treat PNS is to discover and treat the tumor promptly, and provide supportive care for the neurologic deficits with symptomatic treatment and physical therapy. In a few cases, depending on the syndrome and if the patient is in the early stages of the neurologic disease, treatment with immunosuppression may have some effect on the PNS.

Abstract
Paraneoplastic disorders may affect any part of the central or peripheral nervous systems. Although relatively uncommon, these disorders are a significant cause of neurologic morbidity for cancer patients. At least some paraneoplastic syndromes are believed to be caused by an autoimmune reaction against shared tumor-neural antigens. This article summarizes the clinical features of paraneoplastic disorders, the current evidence for autoimmunity, and guidelines for diagnosis and treatment.

Abstract
OBJECTIVES Opsoclonus-myoclonus-ataxia (OMA) syndrome affects 2% to 3% of patients with neuroblastoma. This study examined relationships between long-term neurobehavioral outcomes and potential biologic markers of OMA, including chronic changes on magnetic resonance imaging (MRI) brain scanning and prevalence of late antineuronal antibodies. STUDY DESIGN Children with neuroblastoma and OMA were identified through medical record review of patients treated at the University of California at San Francisco Medical Center from 1979 to 1999. Eleven patients with a mean follow-up time of 7.6 years underwent standard neurologic, neurocognitive, developmental/behavioral, and academic assessments. Consenting patients underwent MRI brain scanning and a blood draw. Sera were analyzed for the presence of antineuronal immunoreactivity. RESULTS Two (18%) patients had no observed neurologic abnormalities, 7 (64%) demonstrated mild deficits, and 2 (18%) had severe neurologic deficits. However, on neurocognitive, behavioral, and academic assessments, 6 (55%) children performed within the average range, 1 (9%) was moderately below average and 4 (36%) had severe cognitive and behavioral deficiencies. Brain MRI in 5 of 5 patients was notable for cerebellar atrophy without supratentorial involvement. Antineuronal activity was detected in sera of 0 of 10 children at follow-up. CONCLUSIONS Certain patients with neuroblastoma associated OMA may achieve average-range neurobehavioral function in spite of residual neurologic abnormalities, with suggestion of continued improvement over time. Late cerebellar atrophy appears to be a common finding regardless of neurologic outcome, whereas antineuronal immune reactivity does not appear to be a long-term feature of OMA.

Abstract
BACKGROUND Opsoclonus-myoclonus-ataxia (OMA) is a paraneoplastic syndrome that occurs in about 2-3% of all cases of neuroblastoma. The histopathologic characteristics of neuroblastoma tumors associated with this syndrome were evaluated in a series of cases and controls. PROCEDURE Pathology slides from a total of 54 neuroblastoma tumors were reviewed blindly. They included 13 tumors associated with opsoclonus-myoclonus and 41 age- and stage-matched controls. All tumors were classified into either the favorable (FH) or unfavorable histology (UH) group according to the International Neuroblastoma Pathology Classification (the Shimada system). Grade of lymphocytic infiltration was evaluated and presence or absence of lymphoid follicles was recorded in the individual tumor tissues. RESULTS Twelve of 13 cases with opsoclonus-myoclonus were in the FH group. Twelve of 13 cases had diffuse (found in every section prepared from the multiple portions of the primary tumor) and extensive (occupying more than 50% of a single of multiple microscopic fields with x 100 magnification) lymphocytic infiltration with lymphoid follicles. Of the 41 control cases (27 FH and 14 UH tumors), 18 had focal areas of lymphocytic infiltration and six showed lymphoid follicles, but none had diffuse or extensive infiltration in their primary tumors. CONCLUSIONS Diffuse and extensive lymphocytic infiltration with lymphoid follicles is a characteristic histologic feature of neuroblastic tumors with opsoclonus-myoclonus. This observation suggests an immune-mediated mechanism for this rare paraneoplastic syndrome.

Abstract
BACKGROUND Opsoclonus-myoclonus-ataxia (OMA) is a paraneoplastic neurologic syndrome affecting 2-3% of children with neuroblastoma. Although children with OMA and neuroblastoma may have higher survival, many experience a significant amount of late neurologic impairment, which may be immunologically mediated. The aim of this study was to compare the outcome of neuroblastoma patients with and without OMA, relating to prognostic factors, treatment, and the presence or absence of anti-neuronal antibodies. PROCEDURE Questionnaires were mailed out requesting information on the current neurologic status of patients who submitted sera at diagnosis to the Children's Cancer Group serum bank from 1980 to 1994. Information was requested on clinical and biological patient characteristics as well as clinical aspects of the patients identified as having OMA syndrome, including presentation and treatment for OMA, late sequelae of OMA, the presence or absence of antineuronal antibodies, and survival. Sera from 16 of the OMA patients and 48 case-controls with neuroblastoma were assayed for anti-neuronal antibodies. RESULTS Of the 675 responses received, 21 patients had OMA. Ninety percent of OMA patients presented with non-metastatic disease, vs. 35% of non-OMA patients. Estimated 3-year survival for the OMA patients with nonmetastatic disease (stage I, II, III) greater than 1 year of age was 100% vs. 77% for similar non-OMA patients (P = 0.0222). At follow-up, 14/19 evaluable OMA patients displayed some form of developmental or neurologic abnormality. There was no significant correlation of late sequelae with antineuronal antibodies, age, time between OMA symptoms and diagnosis, or treatment given for tumor or OMA. There was a significant correlation of late sequelae with lower stage disease (I and II) compared to more advanced disease (III and IV). CONCLUSIONS Patients with OMA and neuroblastoma have excellent survival but a high risk of neurologic sequelae. Favorable disease stage correlates with a higher risk for development of neurologic sequelae. The role of anti-neuronal antibodies in late sequelae of OMA needs further clarification.
