ABSTRACT
Background: Although infrequent, Sydenham's chorea (SC) may occur as a result of injury to the basal ganglia in children with acute rheumatic fever (ARF) secondary to group A Streptococcal infection. Certain hallmarks of SC, such as movement disorders, could be utilized as a predictive marker for carditis. The present study aimed to investigate neurologic and cardiologic symptoms in children with suspected SC after ARF. Methods: All children aged 5-16 who were admitted at Shahid Madani Pediatric Hospital (Tabriz, Iran), with an initial diagnosis of ARF and SC between 2009 and 2022 were included for echocardiographic assessment and prospective follow-up within 6 and 12 months after the start point. The pattern and severity of valvulopathy, as well as the prevalence of Jones criteria for rheumatic fever, were used to assess the effect. The collected data were analyzed using SPSS Statistics software (version 22.0) using Chi square and Fisher's exact tests. P<0.05 was considered statistically significant. Results: The study enrolled 85 children, 36 girls and 49 boys, with a mean age of 9.7±2.7. On the first echocardiography, 42.4% of patients had mitral valve regurgitation (MR), with a predominance of female patients (P=0.04). Of those diagnosed with SC (12 girls and 6 boys), 66.7% showed cardiac involvement, with a higher prevalence of MR in both sexes (P=0.04). The pattern of cardiac involvement after 6 months was significantly different between the groups (P=0.04). However, no such difference was observed during the one-year follow-up (P=0.07). Female sex was found to have a significant relationship with SC localization (P=0.01). Conclusion: In addition to its neurological manifestations, SC can be associated with clinical or subclinical cardiac valve dysfunction that might last for more than a year. In addition to attempting early detection and appropriate management, a precise cardiac and neurologic assessment during admission and follow-up is recommended.A preprint version of this manuscript is available at DOI: 10.21203/rs.3.rs-772662/v1 (https://www.researchsquare.com/article/rs-772662/v1).

Chorea is a very commonly encountered movement disorder; it has various etiologies, and it can have autoimmune, vascular, degenerative, or paraneoplastic etiology. Our patient had acute onset chorea and a strong history of smoking, which made us suspect first vascular followed by paraneoplastic cause. After ruling out common vascular and metabolic causes, his whole body positron emission tomography (PET) scan revealed a mass in the right upper lobe, a biopsy revealed a small cell carcinoma lung and a paraneoplastic panel showed antibodies positive for collapsin response mediator protein 5 antigen (CRMP-5/CV2); the patient was started on immunomodulation, chemotherapy with the variable response, he succumbed to a cardiac event after treatment.

Chorea is a hyperkinetic movement disorder associated with various underlyingconditions, including autoimmune diseases such as antiphospholipid syndrome (APS). APS can manifest with a wide range of neurological symptoms, including chorea. We present a case of a 77-year-old man with subacute generalized chorea secondary to primary APS. Notably, the patient exhibited a left patellar crossed-reflex, a phenomenon rarely documented in chorea cases, the pathophysiology of which has not yet been elucidated. In summary, this case challenges the traditional demographics of antiphospholipid syndrome (APS) by suggesting a potential link between APS and late-age patients. It emphasizes the importance of considering APS in late-onset chorea cases.

Background: Subacute Sclerosing Panencephalitis (SSPE) typically presents with periodic myoclonus; however, a spectrum of movement disorders including dystonia, chorea, tremor, and parkinsonism have also been described. This review aims to evaluate the array of movement disorders in SSPE, correlating them with neuroimaging findings, disease stages, and patient outcomes. Methods: A comprehensive review of published case reports and case series was conducted on patients with SSPE exhibiting movement disorders other than periodic myoclonus. PRISMA guidelines were followed, and the protocol was registered with PROSPERO (2023 CRD42023434650). A comprehensive search of multiple databases yielded 37 reports detailing 39 patients. Dyken's criteria were used for SSPE diagnosis, and the International Movement Disorders Society definitions were applied to categorize movement disorders. Results: The majority of patients were male, with an average age of 13.8 years. Approximately, 80% lacked a reliable vaccination history, and 39% had prior measles infections. Dystonia was the most common movement disorder (49%), followed by parkinsonism and choreoathetosis. Rapid disease progression was noted in 64% of cases, with a disease duration of ≤6 months in 72%. Neuroimaging showed T2/FLAIR MR hyperintensities, primarily periventricular, with 26% affecting the basal ganglia/thalamus. Brain biopsies revealed inflammatory and neurodegenerative changes. Over half of the patients (56%) reached an akinetic mute state or died. Conclusion: SSPE is associated with diverse movement disorders, predominantly hyperkinetic. The prevalence of dystonia suggests basal ganglia dysfunction.

We report the case of a man in his mid-80s with diabetes mellitus who presented to the emergency department with a 1-day history of right-sided choreiform movements and falls. Laboratory tests revealed blood glucose of 597 mg/dL. Non-contrast CT imaging of his head demonstrated a faint hyperdensity involving the left lentiform nucleus and brain MRI showed a hyperintensity in the left basal ganglia on T1-weighted images. These lesions are typical of diabetic striatopathy. Symptoms of hemichorea/hemiballismus did not resolve with glycaemic control and several pharmacological agents were tried with eventual improvement with risperidone. He was discharged to a rehabilitation facility and had mild persistent arm chorea at 6-month follow-up.

BACKGROUND: Subacute sclerosing panencephalitis (SSPE) is a complication of measles, occurring after a latency of 4-10 years. It continues to occur in developing countries although resurgence is being reported from developed countries. Characteristic features include progressive neuropsychiatric issues, myoclonus, seizures, movement disorders and visual impairment. Electroencephalography (EEG) typically shows periodic generalized discharges, and elevated CSF anti-measles antibodies are diagnostic. Movement disorders are being increasingly recognized as part of the clinical spectrum, and range from hyperkinetic (chorea, dystonia, tremor, tics) to hypokinetic (parkinsonism) disorders and ataxia. OBJECTIVES: This article aims to comprehensively review the spectrum of movement disorders associated with SSPE. METHODS: A literature search was conducted in PubMed and EMBASE databases in December 2023 and articles were identified for review. RESULTS: Movement disorders reported in SSPE included hyperkinetic (chorea, dystonia, tremor and tics), hypokinetic (parkinsonism), ataxia and extraocular movement disorders. Myoclonus, a core clinical feature, was the most frequent "abnormal movement." Movement disorders were observed in all clinical stages, and could also be a presenting feature, even sans myoclonus. Hyperkinetic movement disorders were more common than hypokinetic movement disorders. An evolution of movement disorders was observed, with ataxia, chorea and dystonia occurring earlier, and parkinsonism later in the disease. Neuroradiological correlates of movement disorders remained unclear. CONCLUSION: A wide spectrum of movement disorders was observed throughout the clinical stages of SSPE. Most data were derived from case reports and small case series. Multicentric longitudinal studies are required to better delineate the spectrum and evolution of movement disorders in SSPE.

OBJECTIVE: To summarize the clinical characteristics and imaging manifestations of patients with nonketotic hyperglycemic hemichorea (NH-HC) and to explore the possible pathogenesis, diagnosis. and treatment of the disease in order to improve the understanding of this disease and avoid misdiagnosis. METHODS: Retrospective analysis was performed on the case data of five patients with NH-HC admitted to our hospital in recent years. The patients were treated in the department of endocrinology, department of neurology, and department of neurosurgery in our hospital, respectively. Meanwhile, relevant literatures were consulted for further learning. RESULTS: NH-HC is usually presented as a triad of nonketotic hyperglycemia, lateral chorea, and typical imaging manifestations of head magnetic resonance imaging or computed tomography, but the clinical manifestations are not the same, and imaging features may also be different, presenting a diversified trend in clinical practice. All five patients were given glucose-lowering drugs and improved with or without combination of drugs to control symptoms of chorea. CONCLUSION: NH-HC is a rare complication of diabetes, characterized by hyperglycemia and hemichorea. How to identify the extreme situation and make fast judgment is a top priority. Timely and correct control of blood glucose is the key to the treatment, and when necessary, application of dopamine receptor antagonists in patients with combination therapy can accelerate improvement of the clinical symptoms. The prognosis of NH-HC is good, the clinician should strengthen comprehensive understanding of this disease to avoid missed diagnosis or misdiagnosis and enable patients to get more timely and effective treatment.

INTRODUCTION: Subacute adult-acquired hemichorea is a striking presentation with a broad differential, including ischemic, metabolic, and inflammatory causes. CASE: We encountered a 74-year-old woman with rapid onset of hemichorea and associated encephalopathy. Following a thorough workup without identification of clear imaging or laboratory abnormalities, we empirically treated with IVIg. Her hemichorea dramatically improved. Due to relapses of hemichorea, she required repeat immunotherapy with IVIg or high dose steroids followed by maintenance mycophenolate. DISCUSSION: This case of seronegative autoimmune hemichorea highlights the importance of a high index of suspicion for an inflammatory etiology of chorea when other causes are ruled out and performing an immunotherapy trial.

Rheumatic fever is a major cause of cardiovascular morbidity and mortality in low-income and middle-income countries, and it usually occurs at a young age. Adult-onset acute rheumatic fever is a rare condition and usually represents a recurrence of childhood-onset disease. We report a case of an elderly man presenting with rheumatic carditis and rheumatic chorea subsequently diagnosed with adult-onset rheumatic fever.

BACKGROUND: Diabetic striatopathy, also known as hyperglycemic hemichorea-hemiballismus, is a rare movement disorder associated with nonketotic hyperglycemia in patients with poorly controlled diabetes mellitus. The pathophysiology is not fully elucidated but may involve hyperviscosity, ischemia, and alterations in basal ganglia neurotransmitters. CASE PRESENTATION: We present a case of a 64-year-old Asian female patient with longstanding poorly controlled type 2 diabetes mellitus who developed abrupt-onset right-sided hemichorea-hemiballismus. Laboratory results showed hyperglycemia without ketoacidosis. Neuroimaging revealed left putaminal hyperdensity on computed tomography and T1 hyperintensity on magnetic resonance imaging. With insulin therapy and tetrabenazine, her movements improved but persisted at 1-month follow-up. DISCUSSION: This case illustrates the typical features of diabetic striatopathy, including acute choreiform movements contralateral to neuroimaging abnormalities in the setting of nonketotic hyperglycemia. While neuroleptics may provide symptomatic relief, prompt glycemic control is critical given the risk of recurrence despite imaging normalization. CONCLUSION: Diabetic striatopathy should be recognized as a rare disorder that can occur with poorly controlled diabetes. Further study of its pathophysiological mechanisms is needed to better guide management. Maintaining tight glycemic control is essential to prevent recurrence of this debilitating movement disorder.

Nonketotic hyperglycemia may occur as a cause of chorea in patients with chronic decompensated diabetes. Because it is rare and consequently poorly studied, diagnosis and treatment can be delayed. Therefore, our objective was to summarize clinical and radiological features, as well as treatments performed, from previously reported cases to facilitate adequate management in clinical practice. We searched MEDLINE/PubMed, EMBASE, Cochrane, CINAHL, Web of Science, Scopus, and LILACS databases for studies published before April 23, 2021. We included case reports and case series of adults (aged ≥ 18 years) that described hyperglycemic chorea with measurement ofglycated hemoglobin (HbA1c) and cranial magnetic resonance imaging (MRI). Studies were excluded if participants were pregnant women, aged < 18 years, and had no description of chorea and/or physical examination. We found 121 studies that met the inclusion criteria, for a total of 214 cases. The majority of the included studies were published in Asia (67.3%). Most patients were women(65.3%) aged > 65 years (67.3%). Almost all patients had decompensated diabetes upon arrival at the emergency department (97.2%). The most common MRI finding was abnormalities of the basal ganglia (89.2%). There was no difference in patient recovery between treatment with insulin alone and in combination with other medications. Although rare, hyperglycemic chorea is a reversible cause of this syndrome; therefore, hyperglycemia should always be considered in these cases.

INTRODUCTION: Chorea is primarily due to an imbalance of basal ganglia output pathways, often due to dysfunction or degeneration of the caudate nucleus and putamen, and can be due to many causes. METHODS: We reviewed the recent literature to identify newly-recognized causes of chorea, including auto-immune, metabolic, and genetic. We also focused upon developments in mechanisms relating to underlying pathophysiology of certain genetic choreas and advances in therapeutics. RESULTS: Novel autoantibodies continue to be identified as causes of chorea. Both COVID-19 infection and vaccination are reported to result rarely in chorea, although in some cases causality is not clearly established. Advances in genetic testing continue to find more causes of chorea, and to expand the phenotype of known genetic disorders. Deep brain stimulation can be successful in certain circumstances. CONCLUSION: Our understanding of mechanisms underlying this movement disorder continues to advance, however much remains to be elucidated.

Due to their immunocompromised state, recipients of hematopoietic stem cell transplants (HSCTs) are at a higher risk of opportunistic infections, such as that of toxoplasmosis. Toxoplasmosis is a rare but mortal infection that can cause severe neurological symptoms, including confusion. In immunosuppressed individuals, such as those with acquired immunodeficiency syndrome (AIDS), toxoplasmosis can cause movement disorders, including hemichorea-hemiballismus. We present the case of a 54-year-old Caucasian male with a history of hypertension and JAK-2-negative primary myelofibrosis who underwent an allogeneic peripheral blood stem cell transplant from a related donor. After the development of acute changes in mental status, left-sided weakness, and left-sided hemichorea-hemiballismus post-transplant, the patient was readmitted to the hospital. Subsequent testing included an magnetic resonance imaging (MRI) of the brain, which revealed multiple ring-enhancing lesions around the thalami and basal ganglia, as well as a cerebrospinal fluid tap that tested positive for toxoplasmosis. The patient was initially treated with intravenous clindamycin and oral pyrimethamine with leucovorin. The completion of treatment improved the patient's mental status but did not improve his hemichorea-hemiballismus. This case illustrates an uncommon complication associated with central nervous system (CNS) toxoplasmosis in stem cell transplant recipients. Due to its rarity, cerebral toxoplasmosis in immunocompromised patients often remains undetected, particularly in HSCT patients who are immunosuppressed to improve engraftment. Neurological and neuropsychiatric symptoms due to toxoplasmosis may be misidentified as psychiatric morbidities, delaying appropriate treatment. Polymerase chain reaction (PCR) assays offer methods that are sensitive and specific to detecting toxoplasmosis and provide opportunities for early intervention.

Chorea can be an initial manifestation of systemic lupus erythematosus (SLE) or antiphospholipid syndrome (APS). It has been mostly described in younger female adults in association with other manifestations of SLE. When chorea appears as an initial and only manifestation in SLE/APS patients, the establishment of the correct diagnosis is difficult, and it may be initially attributed to a more common aetiology. Here we report an elderly man who presented with a new onset of right-sided chorea without other clinical manifestations of SLE/APS. He started on steroids a year later, however, there was no improvement. His chorea was symptomatically managed along with aspirin, and hydroxychloroquine as he refused to be on additional immunosuppression. Anticoagulation was relatively contraindicated, and also not favoured by this patient; therefore, aspirin was initiated. Even in elderly patients, once the common etiologies of chorea have been worked up, we suggest doing a rheumatological evaluation. Early diagnosis and prompt treatment can prevent persistent neurological abnormality.
