Greece and Rome at the Crystal Palace : classical sculpture and modern Britain, 1854-1936
The marble halls of the British Museum might seem the natural habitat for classical sculpture, but in the nineteenth century its sombre displays were far from being the only place that people encountered antiquities. From 1854, a rival collection of classical sculpture, comprising plaster casts from major European museums and scaled down architectural features, was on show in the South London suburb of Sydenham, in the Crystal Palace which had housed the Great Exhibition of 1851. By the late 1850s, two million visitors were passing through the glass doors of the Sydenham Crystal Palace each year, more than twice as many as recorded at the British Museum. Many more people, and from a greater variety of social strata, saw the painted cast of the Parthenon frieze in Sydenham than the original in Bloomsbury. Utilizing an extensive variety of archival material, including diaries, scrapbooks and photographs, Greece and Rome at the Crystal Palace evokes visitor experiences at Sydenham, and examines the discussion that arose around the presentation of classical plaster casts to a mass audience. It uncovers the social, political, and aesthetic role of ancient Greek and Roman sculpture in modern Britain, assessing how classical art figured in debates over design reform, taste, beauty and morality, class and gender, and race and imperialism.0Readership: Scholars and students interested in the treatment, display, and historical and cultural significance of classical sculpture at the Crystal Palace at Sydenham, and art history, classical studies, museum studies, and classical archaeology more generally.
Book
After 1851
Echoing Joseph Paxton's question at the close of the Great Exhibition, 'What is to become of the Crystal Palace?', this interdisciplinary essay collection argues that there is considerable potential in studying this unique architectural and art-historical document after 1851, when it was rebuilt in the South London suburb of Sydenham. It brings together research on objects, materials and subjects as diverse as those represented under the glass roof of the Sydenham Palace itself; from the Venus de Milo to Sheffield steel, souvenir 'peep eggs' to war memorials, portrait busts to imperial pageants, tropical plants to cartoons made by artists on the spot, copies of paintings from ancient caves in India to 1950s film. Essays do not simply catalogue and collect this eclectic congregation, but provide new ways for assessing the significance of the Sydenham Crystal Palace for both nineteenth- and twentieth-century studies. The volume will be of particular interest to researchers and students of British cultural history, museum studies, and art history.

Sydenham Chorea in Sudan; Presentation Panorama
Sydenham's chorea (SC) is the most common form of acquired chorea in childhood, it is considered a neurological complication of streptococcal pharyngitis. In this study, we aimed to determine the clinical pattern, association of Sydenham's chorea with other manifestations of acute rheumatic fever, and the laboratory findings of Sydenham's chorea among Sudanese patients.
A prospective cross-sectional study involving fifty patients of various ages diagnosed with Sydenham's chorea and followed up at The National Center for Neurological Sciences from January 2017 to November 2019. Data were obtained after patients' consent through personal interviews or personal review of patients' records via a structured questionnaire composed of demographic data, symptoms, co-morbid illness, risk factors, physical examination, and related investigations.
About 50 patient was enrolled in this study with a median age of 13.7 years. Females were (n=35) (70%) and (30%) (n=15) s were males. Generalized chorea was seen in 33 (66%) and hemichorea in 17 (34%) patients. Weakness (38%) and hypotonia (46%) were common, such as behavior change (44%), dysarthria (70%), gait change (18%), and deterioration of handwriting (12%). Arthritis occurred in (36%), carditis in 30 (60%), both arthritis and carditis in 18 (36%), and pure chorea in 14 (28%). Erythema marginatum and subcutaneous nodules were not observed in our patients. Only 13 patients (26%) gave a history of pharyngitis.
Sydenham chorea is more common in young female Sudanese, with a familial predominance and a tendency towards mitral valve disease. All pediatric Patients with chorea should be screened for Sydenham's chorea.

Behavioral, Pharmacological, and Immunological Abnormalities after Streptococcal Exposure: A Novel Rat Model of Sydenham Chorea and Related Neuropsychiatric Disorders
Group A streptococcal (GAS) infections and autoimmunity are associated with the onset of a spectrum of neuropsychiatric disorders in children, with the prototypical disorder being Sydenham chorea (SC). Our aim was to develop an animal model that resembled the behavioral, pharmacological, and immunological abnormalities of SC and other streptococcal-related neuropsychiatric disorders. Male Lewis rats exposed to GAS antigen exhibited motor symptoms (impaired food manipulation and beam walking) and compulsive behavior (increased induced-grooming). These symptoms were alleviated by the D2 blocker haloperidol and the selective serotonin reuptake inhibitor paroxetine, respectively, drugs that are used to treat motor symptoms and compulsions in streptococcal-related neuropsychiatric disorders. Streptococcal exposure resulted in antibody deposition in the striatum, thalamus, and frontal cortex, and concomitant alterations in dopamine and glutamate levels in cortex and basal ganglia, consistent with the known pathophysiology of SC and related neuropsychiatric disorders. Autoantibodies (IgG) of GAS rats reacted with tubulin and caused elevated calcium/calmodulin-dependent protein kinase II signaling in SK-N-SH neuronal cells, as previously found with sera from SC and related neuropsychiatric disorders. Our new animal model translates directly to human disease and led us to discover autoantibodies targeted against dopamine D1 and D2 receptors in the rat model as well as in SC and other streptococcal-related neuropsychiatric disorders.

Preliminary data on prednisone effectiveness in children with Sydenham chorea
The objective of the study is to evaluate the efficacy of corticosteroids in Sydenham chorea. This is a retrospective observational study. Clinical information of children with Sydenham chorea were collected. Outcome of Sydenham chorea was evaluated in consideration of presence or absence of corticosteroid therapy. Thirty patients were enrolled. A total of 15 were treated with prednisone, 15 received symptomatic drugs or no treatment. Patients who were treated with prednisone showed faster improvement (4 vs 16 days; p = 0.002) and shorter median time of remission (30 vs 135 days; p < 0.001).Conclusion: Our study showed that corticosteroid therapy is an effective treatment of Sydenham chorea.What is Known:• Steroid treatment in Sydenham chorea is widely used but it is not standardized.• Few manuscript report a beneficial use of steroids in Sydenham chorea if compared with no treatment.What is New:• Steroid treatment seems to be effective in both clinical remission and clinical improvement of symptoms among patients with Sydenham chorea.• Steroid treatment seems to be superior to conventional treatment.

Hello from the Other Side: How Autoantibodies Circumvent the Blood–Brain Barrier in Autoimmune Encephalitis
Antibodies against neuronal receptors and synaptic proteins are associated with autoimmune encephalitides (AE) that produce movement and psychiatric disorders. In order to exert their pathological effects on neural circuits, autoantibodies against central nervous system (CNS) targets must gain access to the brain and spinal cord by crossing the blood-brain barrier (BBB), a tightly regulated gateway formed by endothelial cells lining CNS blood vessels. To date, the pathogenic mechanisms that underlie autoantibody-triggered encephalitic syndromes are poorly understood, and how autoantibodies breach the barrier remains obscure for almost all AE syndromes. The relative importance of cellular versus humoral immune mechanisms for disease pathogenesis also remains largely unexplored. Here, we review the proposed triggers for various autoimmune encephalopathies and their animal models, as well as basic structural features of the BBB and how they differ among various CNS regions, a feature that likely underlies some regional aspects of autoimmune encephalitis pathogenesis. We then discuss the routes that antibodies and immune cells employ to enter the CNS and their implications for AE. Finally, we explore future therapeutic strategies that may either preserve or restore barrier function and thereby limit immune cell and autoantibody infiltration into the CNS. Recent mechanistic insights into CNS autoantibody entry indicate promising future directions for therapeutic intervention beyond current, short-lived therapies that eliminate circulating autoantibodies.

Rare Recurrence of Sydenham Chorea in an Adult: A Case Report
Sydenham chorea is thought to be an autoimmune condition that usually develops following a group A beta-hemolytic streptococcal infection.The onset of Sydenham chorea in adults is rare and most of the adult cases usually are secondary to recurrence following childhood illness. Risk factors for chorea recurrence include irregular antibiotic prophylactic use, failure to reach remission within 6 months, and symptom persistence for longer than a year.
A 27-year-old young adult Ethiopian female patient with chronic rheumatic valvular heart disease for the last 8 years experienced repetitive uncontrollable movements of her extremities and torso for three years prior to her current visit. Physical examination was significant for holosystolic murmur at the apical area radiating to the left axilla and choreiform movements apparent on all limbs and trunk. Investigations were significant for mildly raised ESR, echocardiography findings of thickened mitral valve leaflets and severe mitral regurgitation. She was successfully treated with valproic acid and the frequency of penicillin injection was made every 3 weeks with no recurrence for the first 3 months follow-up period.
We believe that this is the first case report of adult onset recurrent Sydenham chorea (SC) from a resource-limited setting. Though Sydenham chorea and its recurrence is rare in adults, it should be considered in adults after ruling out other competing differential diagnoses. Because of the lack of evidence on treatment of such rare cases, individualized mode of therapy is advised. Valproic acid is preferred for symptomatic treatment and more frequent benzathine penicillin G injections, for example every three weeks, may help in the prevention of recurrence of Sydenham chorea.

Treatment of Disorders of Tone and Other Considerations in Pediatric Movement Disorders
Pediatric movement disorders (PMDs) consist of a heterogeneous group of signs and symptoms caused by numerous neurological diseases. Different neurological disorders in children also share overlapping movement disorders making a diagnosis of the underlying cause of the movement disorder challenging. The similarity of the symptoms across multiple disease types suggests that there may be a final common motor pathway causing the overlapping movement disorders. There are numerous disorders in children associated with disturbances in tone and involuntary movements. This chapter will focus primarily on those disorders that involve abnormalities of tone and other important considerations of pediatric movement disorders. This chapter will address rating scales and goals for treatment and will include a review of symptomatic treatment and, where possible, the treatment of the underlying disease processes. The chapter will review representative disorders, including an inborn error of metabolism, an autoimmune disorder, and a group of neurodegenerative disorders. These examples demonstrate how the disorder's underlying pathophysiology results in a specific approach to the underlying disease and the associated conditions of tone and involuntary movements. Finally, the multiple treatment options for cerebral palsy and considerations of cerebral palsy mimics will be discussed.
