ABSTRACT
OBJECTIVE: The aim of this study was to investigate the relationship between C-reactive protein and erythrocyte sedimentation rate and neutrophil-to-lymphocyte, platelet-to-lymphocyte, and monocyte-to-lymphocyte ratios in acute rheumatic fever in children. METHOD: In this retrospective study, 182 patients with acute rheumatic fever and 173 controls were included. Complete blood count parameters, and neutrophil-to-lymphocyte, monocyte-to-lymphocyte, and platelet-to-lymphocyte ratios were recorded for all the patients underwent transthoracic echocardiography. RESULTS: Neutrophil-to-lymphocyte, monocyte-to-lymphocyte, and platelet-to-lymphocyte ratios were significantly higher in patients with rheumatic heart disease than patients without cardiac involvement (p < 0.05). C-reactive protein and erythrocyte sedimentation rate levels were found to have a positive correlation with neutrophil-to-lymphocyte (r = 0.228, p = 0.001; r = 0.355, p = 0.001), platelet-to-lymphocyte (r = 0.227, p = 0.01; r = 0.149, p = 0.005), and monocyte-to-lymphocyte ratios (r = 0.117, p = 0.005; r = 0.107, p = 0.044). Cardiac involvement was present in 152 (83.5%) of the patients. Neutrophil-to-lymphocyte, monocyte-to-lymphocyte, and platelet-to-lymphocyte ratios were significantly higher in patients with rheumatic heart disease than patients without cardiac involvement (p < 0.05). Patients with carditis were grouped according to mitral, aortic, or both valve involvement but there was no significant difference between the groups with respect to neutrophil-to-lymphocyte, monocyte-to-lymphocyte, and platelet-to-lymphocyte ratios. In addition, neutrophil-to-lymphocyte and monocyte-to-lymphocyte ratios were significantly higher in patients with Sydenham's chorea than without chorea (p < 0.05). CONCLUSION: Neutrophil-to-lymphocyte, platelet-to-lymphocyte, and monocyte-to-lymphocyte ratios may help make the diagnosis of acute rheumatic fever and its prognosis by serial measurements in follow-up but none of them tell us the severity of carditis. Also, this is the first study showing the positive correlation between Sydenham's chorea and neutrophil-to-lymphocyte and monocyte-to-lymphocyte ratios. Further studies are needed to confirm this hypothesis, as this is the first study in the literature on this topic.

Mutations in RNF216 have been found to be associated with autosomal recessive Huntington-like disorder. Here, we describe a patient with Huntington-like disorder caused by a novel de novo RNF216 mutation. The patient started to have choreatic movements of both hands, slowly progressing to head, face, and four extremities, with prominent cognitive deterioration. White matter lesions in cerebral hemispheres and brainstem, cerebellar atrophy, and low gonadotropin serum levels have been demonstrated. We have identified a homozygous deletion of exon 2 in the RNF216 gene by whole-exome sequencing. Our findings increased genetic knowledge of autosomal recessive Huntington-like disorder and extended the ethnic distribution of RNF216 mutations.

RATIONALE: Mutations of the NKX2-1 gene are associated with brain-lung-thyroid syndrome, which is characterized by benign hereditary chorea, hypothyroidism, and pulmonary disease with variable presentation. Surfactant protein C (SFTPC) gene mutations result in chronic interstitial lung disease in adults or severe neonatal respiratory distress syndrome. PATIENT CONCERNS: Recurrent hypoxemia was observed shortly after birth in a baby at a gestational age of 40 weeks and birth weight of 3150âg. The need for respiratory support gradually increased. He had hypothyroidism and experienced feeding difficulties and irritability. DIAGNOSIS: Genetic examination of the peripheral blood revealed combined mutations of the NKX2-1 and SFTPC genes. INTERVENTIONS: The patient was administered respiratory support, antibiotics, low-dose dexamethasone, supplementary thyroxine, venous nutrition, and other supportive measures. OUTCOMES: The patient's guardian stopped treatment 3 months after commencement of treatment, due to the seriousness of his condition and the patient died. LESSONS: Combined mutations of NKX2-1 and SFTPC genes are very rare. Thus, idiopathic interstitial pneumonia with hypothyroidism and neurological disorders require special attention.

Background: Paraneoplastic chorea is typically a subacute progressive hyperkinetic movement disorder. The mainstay of treatment is managing the underlying neoplasm. However, the clinical course may be variable, and effective symptomatic management can precede the start of cancer treatment. Case report: A 63-year-old man presented with insidious onset, slowly progressive generalized chorea for 1 year, later diagnosed as anti-CV2/CRMP5 autoantibody positive paraneoplastic chorea. His chorea was markedly improved with intravenous amantadine. Discussion: In patients with anti-CV2/CRMP5 autoantibody-related chorea, sequential follow-up of brain magnetic resonance imaging reveals progression from active inflammation to atrophy. Our report highlights the efficacy of intravenous amantadine in paraneoplastic chorea.

Non-ketotic hyperglycaemic hemichorea-hemiballismus (NHHH) is commonly seen among elderly Asian women with type 2 diabetes mellitus. Here, we present a case of a 16-year-old Filipina with type 1 diabetes mellitus who is poorly compliant to her medications and subsequently developed right hemichorea-hemiballismus (HH). She was initially admitted with hyperglycaemia but was negative for ketonuria or metabolic acidosis. Neuroimaging showed bilateral lentiform nuclei and left caudate hyperdensities on CT and T1-weighted hyperintensity on MRI. Blood glucose was controlled with insulin. Haloperidol and clonazepam were started for the HH with gradual resolution of symptoms in 6 weeks. This is the fifth reported case of NHHH seen among the paediatric age group. NHHH in the paediatric population is clinically and radiographically similar to NHHH seen among adults. Correction of hyperglycaemia results in clinical improvement and radiographic resolution of lesions but persistent cases may necessitate specific treatment targeted towards the abnormal movements.

Frontotemporal dementia (FTD) is clinically characterized by behavioral changes, language impairment, and executive dysfunction. FTD usually belongs to the frontotemporal lobar degeneration (FTLD) disease group, and its familial forms are dominantly inherited and linked to a group of genes relevant to frontal and temporal brain pathology, such as MAPT, GRN, C9ORF72, TARDBP, CHMP2B, VCP, and FUS. However, FTD can also be associated with different clinical or pathological phenotypes caused by mutations in other genes, whose heredity can be dominant or recessive. In this work we report on a familial case of FTD characterized by behavioral changes and aphasia, very early onset and very long duration, choreic movements, and white matter lesions at magnetic resonance imaging. We performed a wide-range genetic analysis, using a next generation sequencing approach, to evaluate a number of genes involved in neurodegeneration. We found a previously unreported compound heterozygous mutation in TREM2, that is commonly associated with the recessively inherited Nasu-Hakola disease. We discuss the differential diagnosis to be taken into account in cases of FTD presenting with atypical features.

Hyperglycemia-associated chorea-ballism (HCB) is an infrequent neurological syndrome occurring predominantly in elderly females and in the setting of non-ketotic hyperglycemia (NKH). A systematic review was conducted in accordance with the PRISMA statement. Studies published between 1980 and 2018 that reported demographic, clinical, laboratory and imaging features from patients with HCB were screened. 136 studies describing 286 patients were included in the analysis. The patients included had a median age of 72 years; those with ketotic hyperglycemia (KH) were older (p<0.001). Women and NKH patients were the most frequently affected (63% and 92%, respectively). The median glucose level at admission was 420 mg/dL (IQR 328-535), and was significantly higher in KH (p=0.009). Moreover, the absence of a clear lesion on imaging studies and the finding of bilateral imaging evidence of lesions were each more frequent in the KH group (p=0.036 and p=0.008, respectively). 48 cases (19.4%) presented with bilateral CT/MRI lesions, having higher values of plasma osmolarity compared with the patients with unilateral lesions (p=0.011). Every patient received hypoglycemic treatment, but only 174 (60.84%) were prescribed neuroleptics. 213 patients (84.86%) showed a total recovery, after a median of 14 days (IQR 3-31). Bilateral chorea-ballism was supported by bilateral imaging evidence of involvement in only 60% of the cases (positive predictive value). Patients not prescribed neuroleptics, with negative lentiform nucleus involvement, and age within the third tertile (≥ 78 years) had an odds ratio of 6.6 (CI 95% 1.18-141.10) for a complete clinical recovery. Significant differences were identified between types of hyperglycemia and regarding the clinical and imaging laterality features. Furthermore, the predictor variables evaluated showed potential utility for assessing the prognosis of HCB patients.

Chorea is associated with involuntary movement and may occur via an autoimmune mechanism. Until now, we treated immune-mediated chorea with glucocorticoids and cyclophosphamide as the efficacy of mycophenolate mofetil (MMF) therapy for this condition was unknown. Here, we report two cases of antiphospholipid antibody (aPL)-associated chorea that were cured by MMF. Measurement of aPL could help for future management of chorea patients. This report provides new insight into the beneficial effects of MMF on aPL-associated chorea.

Neuroacanthocytosis (NA) syndromes are a group of rare diseases characterized by neurological disorders and misshaped spiky red blood cells (acanthocytes) including Chorea-Acanthocytosis (ChAc), McLeod syndrome (MLS), Huntington disease-like 2 (HDL 2), pantothenate kinase-associated neurodegeneration (PKAN), abeta- and hypobetalipoproteinemia and aceruloplasminemia. This clinically and genetically heterogeneous group of diseases shares main clinical features presenting most often as a hyperkinetic movement disorder. Even though these are long noted disease conditions, we still know only little on the underlying disease mechanisms. The current review focuses upon ChAc as the core entity of NA syndromes caused by mutations in the VPS13A gene. The support of patient organizations and the ERA-NET initiative yielded to different multidisciplinary efforts with significant progress on our understanding of ChAc. Disturbances in two pathways are currently considered to be significantly involved in the pathophysiology of ChAc, namely elevated Lyn kinase phosphorylation and decreased signaling via Phosphoinositide 3-kinase (PI3K). These recent developments may reveal potential drugable targets for causative therapies of ChAc.

Background: Huntington's Disease-like 2 (HDL2) is classified as a neuroacanthocytosis; however, this remains unverified. We aim to determine if acanthocytes are present in HDL2 and whether acanthocytes can differentiate HDL2 from Huntington's disease (HD). Methods: We prospectively compared 13 HD and 12 HDL2 cases against 21 unaffected controls in Johannesburg. Blood smears were prepared using international standards and reviewed by at least two blinded reviewers. An acanthocytosis rate of greater than 1.2% in the dry smear or greater than 3.7% in the wet smear was designated a priori as the threshold for clinical significance based on previously established standards. Flow cytometry was performed on all but four of the cases. Red cell membrane protein analysis was performed on all participants. Results: There were 12 HDL2, 13 HD, and 21 controls enrolled. None of the HD or HDL2 participants had defined acanthocytosis or other morphological abnormalities. None of the HD or HDL2 cases had evidence of an abnormal band 3. Discussion: Acanthocytosis was not identified in either HDL2 or HD in our patient population. Our results, based on the first prospective study of acanthocytes in HDL2 or HD, suggest that screening for acanthocytes will not help establish the diagnosis of HD or HDL2, nor differentiate between the two disorders and raises the question if HDL2 should be placed within the neuroacanthocytosis syndromes.

Encephalopathy associated with autoantibodies to IgLON5 is a novel syndrome characterized by a distinct sleep disorder and brain-stem involvement. Since the initial description of this encephalopathy in 2014, only a few additional patients have been reported (Simabukuro et al., 2015). In this paper, we report a new case of anti-IgLON5 antibodies with major symptoms of chorea and parkinsonism, and responsive to immunotherapy.

Hyperglycemia rarely manifests as hemichorea-hemiballism (HH), which is characterized by simple partial motor seizures. One of the difficulties in the management of hyperglycemia-induced HH is the failure to recognize this entity due to its relatively uncommon presentation. We herein present a case series of hyperglycemia-associated dyskinesias, highlighting the different possible clinical presentations of this entity. Both hyperglycemia and hyperosmolality are probable predisposing factors, while ketoacidosis has a protective role in preventing the dyskinesias. One of our patients had ketotic hyperglycemia leading to HH, a previously unreported finding. Early recognition of this entity is crucial as prompt glycemic control leads to the resolution of symptoms and signs.
