Hemichorea Secondary to Non-Ketotic Hyperglycemia as the Presenting Manifestation of Diabetes Mellitus.

Nonketotic hyperglycemia is an unusual and rare cause of hemichorea. Hemichorea though rare may be the initial manifestation of diabetes mellitus. Correction of the hyperglycemia usually results in total resolution of the signs and symptoms. We present the case of a 71 yr old female, who presented with subacute onset of choreiform movement of left upper and lower extremities over 8 days. Her serum glucose level was 416 mg/dl and urine ketone bodies were absent. Computed tomography of brain showed right caudate nucleus and right lentiform nucleus hyperdensity suggesting hyperglycemia related hemichorea syndrome. Restoration of euglycemia along with treatment with haloperidol and tetrabenazine led to eventual resolution of all symptoms. So, nonketotic hyperglycemia should be kept as a differential diagnosis in a patient with hemichorea.

Chorea and Orofaciolingual Dystonia in a 40 Year Old Male.

Neuroacanthocytosis is a heterogeneous group of disorders which result in progressive neurodegeneration, predominantly of the basal ganglia, and erythrocyte acanthocytosis. We report a case of neuroacanthocytosis with typical phenotype of choreoacanthocytosis. A 40 year male presented with features of chorea with orofaciolingual dystonia producing eating and speech difficulties. There were features of self mutilation in form of lip and tongue biting. Peripheral blood smear examination revealed acanthocytes in our patient. Neuroimaging showed bilateral caudate atrophy and nerve conduction study showed motor axonal neuropathy. This case report describes the typical features and investigations to diagnose this rare disorder which is usually underdiagnosed.

Stroke incidence, mortality, subtypes in rural and urban populations in five geographic areas of India (2018-2019): results from the National Stroke Registry Programme.

Background: Increasing stroke burden in India demands a long-term stroke surveillance framework. Earlier studies in India were urban-based, short term and provided limited data on stroke incidence and its outcomes. This gap is addressed by the establishment of five population-based stroke registries (PBSRs) of the National Stroke Registry Programme, India. This paper describes stroke incidence, mortality and age, sex, and subtypes distribution in the five PBSRs with urban and rural populations. Methods: First-ever incident stroke patients in age group ≥18 years, resident for at least one year in the defined geographic area, identified from health facilities were registered. Death records with stroke as the cause of death from the Civil Registration System (CRS) were included. Transient ischemic attack (TIA) was excluded. Three PBSRs (Cuttack, Tirunelveli, Cachar) included urban and rural populations. PBSRs in Kota and Varanasi were urban areas. The crude and age-standardized incidence rate (ASR) by age, sex, and residence (urban and rural), rate ratios of ASR, case fatality proportions and rates at day 28 after onset of stroke were calculated for years 2018-2019. Findings: A total of 13,820 registered first-ever stroke cases that included 985 death certificate-only cases (DCOs) were analysed. The pooled crude incidence rate was 138.1 per 100,000 population with an age-standardized incidence rate (ASR) of 103.4 (both sexes), 125.7 (males) and 80.8 (females). The risk of stroke among rural residents was one in seven (Cuttack), one in nine (Tirunelveli), and one in 15 (Cachar). Ischemic stroke was the most common type in all PBSRs. Age-standardized case fatality rates (ASCFR) per 100,000 population for pooled PBSRs was 30.0 (males) and 18.8 (females), and the rate ratio (M/F) ranged from 1.2 (Cuttack) to 2.0 (Cachar). Interpretation: Population-based registries have provided a comprehensive stroke surveillance platform to measure stroke burden and outcomes by age, sex, residence and subtype across India. The rural-urban pattern of stroke incidence and mortality shall guide health policy and programme planning to strengthen stroke prevention and treatment measures in India. Funding: The National Stroke Registry Programme is funded through the intramural funding of the Indian Council of Medical Research, Department of Health Research, Ministry of Health and Family Welfare, India.

Monomelic amyotrophy with clinico-radiological and electrophysiological evaluation: A study from Eastern India.

Background: Monomelic amyotrophy (MMA) is a benign, rare, sporadic disorder of adolescent and young adults with male predominance, where neurogenic amyotrophy is restricted to an upper or lower limb. It is a variant of lower motor neuron disorder with insidious onset and slow progression for 2-4 years. Paucity of cohort studies as well as relative unawareness among physicians in eastern India stimulated us to do this work. Material and Methods: Prospective observational study involving 140 cases of MMA from 2012 to 2016, conducted at S.C.B.Medical College, cuttack, Odisha to evaluate clinical profile, electrophysiology and radiological features. All the data were analysed & subjected to statistical analysis through SPSS software version 24. Results: Mean age at onset and presentation were 19.6yrs and 21.7yrs respectively and the average duration 3.2yrs. Upper limb involvement was more common (91.4%) with distal affection (83%) more than proximal (7%). Isolated Leg amyotrophy found in 12 cases (~9%) and 10 cases were having thigh weakness & atrophy. B/L Upper Limb distal involvement was present in 18.5% cases asymmetrically. Family history found in~2.8%. Autonomic symptoms were present in affected and bilateral homologous Limb in 21%, 5.8%(~6%) patients. Changes in electromyography (EMG) were present in affected limb (100%) and clinically unaffected limb (15%). Conclusion: MMA is a benign disease of young males with weakness and atrophy confined to unilateral limb or asymmetrical homologous limb and areflexia without sensory loss. It progresses variably for 2-3 years followed by stabilization without progression to Motor neuron disease.

Study of Clinicoradiological Profile and Prognosis of Longitudinally Extensive Transverse Myelitis from a Single Tertiary Center in Eastern India.

CONTEXT: Longitudinally extensive transverse myelitis (LETM) is defined as a hyperintense spinal cord lesion extending over three or more vertebral levels on sagittal T2-weighted spinal magnetic resonance imaging (MRI). Among the different causes of LETM, neuromyelitis optica (NMO) is the most common and associated with bad prognosis. AIMS: We aimed to study the clinicoradiological profile, etiology, and prognosis of LETM. SETTINGS AND DESIGN: This is a hospital-based cross-sectional prospective study. SUBJECTS AND METHODS: The study included 37 patients who presented with paraplegia/paresis or quadriplegia/paresis with MRI spine showing LETM. They were analyzed for their clinical features, routine blood parameters, MRI findings, serum aquaporin 4 (AQP4) antibodies. All patients were followed up for 1 year for prognosis. STATISTICAL ANALYSIS USED: Data analysis was performed using SPSS software (version 17, SPSS Inc.; Chicago, IL, USA). The different groups were compared with each other using Chi-square test. RESULTS: The mean age in our series was 35.97 ± 13.2 years. There was a slight female predominance of LETM in our series with a female: male ratio of 1.05:1. Thoracic spinal cord segments were the most commonly (56.76%) affected. The tendency to involve three to five segments is more common (40.54%). Serum AQP4 antibody (Ab) test was done in 26 patients with LETM. Among them, AQP4 Ab was found positive in nine patients (34.62%). A total of 22 patients (59.46%) were clinically diagnosed as NMO, 4 patients as postinfectious myelitis, 1 each in tuberculous myelitis and subacute combined degeneration, and 9 were idiopathic LETM. Prognosis of LETM in the form of Expanded Disability Status Scale at 1 year was poor in patients with NMO particularly those with positive AQP4 Ab. CONCLUSION: NMO is the most common cause of LETM. Because of poor prognosis of LETM in patients with NMO, particularly those with positive AQP4 Ab, it is very essential for early and accurate diagnosis of etiology of LETM, so that appropriate treatment can be provided to the patient.

Glutaric Aciduria Type I: A Rare Metabolic Disorder Mimicking as Choreoathetoid Cerebral Palsy.

Glutaric aciduria type I (GA I) is an autosomal recessive inborn error of metabolism caused by a deficiency of the enzyme glutaryl-CoA dehydrogenase. This disorder is characterized by progressive dystonia, choreoathetosis, and dyskinesia. It is often misdiagnosed as athetoid cerebral palsy. Laboratory evaluation usually demonstrates increased urinary excretion of gluataric acid and 3-hydroxyglutaric acid. We report a case of a 7-year-old boy presenting with choreoathetosis and dystonia, mimicking as choreoathetoid cerebral palsy. The presence of characteristic neuroimaging and biochemical studies led to the diagnosis of GA I.

Concurrent intramedullary spinal cord and multiple intracranial tuberculomas with tuberculous optic neuritis: A rare case report.

Tuberculosis (TB) remains a worldwide burden, with a large majority of new active TB cases occurring in underdeveloped and developing countries. Tuberculous meningitis (TBM) is one of the common infections of central nervous system. Other manifestations include intracranial tuberculoma, tubercular brain abscess, spinal tuberculoma, and granulomatous arachnoiditis. Visual impairment in TBM may be due to optic neuritis, optochiasmatic arachnoiditis (OCA), tuberculoma in the chiasmatic region or in the optic pathways, chorioretinitis, secondary to hydrocephalus and increased intracranial pressure, and finally due to ethambutol toxicity. We report a case of young girl with concurrent spinal cord intramedullary tuberculoma and multiple intracranial tuberculomas with TBM and bilateral visual impairment due to tuberculous optic neuritis.
