Utility of the RIPS Scale and 2CAN Score for In-Hospital Stroke Prediction.

Background: In-hospital strokes are a small but sizeable proportion of all strokes. Identification of in-hospital strokes is confounded by stroke mimics in as many as half of in-patient stroke codes. A quick scoring system based on risk factors and clinical signs during the initial evaluation of a suspected stroke might be helpful to distinguish true strokes from mimics. Two such scoring systems based on ischemic and hemorrhagic risk factors are the risk for in-patient stroke (RIPS) and the 2CAN score. Materials and Methods: This prospective clinical study was conducted at a quaternary care hospital in Bengaluru, India. All hospitalized patients aged 18 years and above for whom a "stroke code" alert was recorded during the study period of January 2019 to January 2020 were included in the study. Results: A total of 121 in-patient "stroke codes" were documented during the study. Ischemic stroke was the most common etiological diagnosis. A total of 53 patients were diagnosed to have ischemic stroke, 4 had intracerebral hemorrhage, and the rest were mimics. Receiver operative curve analysis was performed and at a cut-off of RIPS ≥3, it predicts stroke with a sensitivity of 77% and a specificity of 73%. At a cut-off of 2CAN ≥3, it predicts stroke with a sensitivity of 67% and a specificity of 80%. RIPS and 2CAN significantly predicted stroke. Conclusions: There was no difference in the use of either RIPS or 2CAN for differentiating stroke from mimics, and hence they may be used interchangeably. They were statistically significant with good sensitivity and specificity, as a screening tool to determine in-patient stroke.

Hypodensities within Hematoma is Time-Dependent and Predicts Outcome after Spontaneous Intracerebral Hemorrhage.

BACKGROUND: Non-contrast CT (NCCT) brain imaging biomarkers of hematoma expansion in intracerebral hemorrhage (ICH) has gained relevance in recent times. Though intra-hematoma hypodensities (IHH) can predict hematoma expansion and outcome, it is postulated to be time-dependent. AIM: To assess the differential prevalence of IHH in spontaneous ICH over time and assess its predictive valve in early hematoma expansion and functional outcome at 3 months. MATERIAL AND METHODS: Patients with ICH within 48 h of stroke onset were included. Baseline clinical and demographic data were collected. Baseline NCCT brain was analyzed for hematoma volume, characterization of IHH, with 24-hours follow-up NCCT hematoma volume calculated for identification of hematoma expansion. Poor functional outcome was defined as mRS ≥3. RESULTS: Around 92 subjects were included in the study. IHH was found in 40%. Prevalence of IHH was higher in those with baseline NCCT performed within 3 h of symptom onset compared to those beyond 3 h (71% vs 29%, P = 0.002). The hematoma expansion was more common in patients with IHH compared to those without (54% vs 29%; P = 0.02). Multivariate analysis revealed the presence of IHH (rather than pattern or number) to be strongly associated with poor functional outcome at 3 months (OR 3.86; 95% CI: 1.11-13.42, P = 0.03). CONCLUSION: There is a decreasing prevalence of IHH as the time from symptom onset to NCCT increases. Nevertheless, its presence is significantly associated with hematoma expansion and predicted poor short-term functional outcomes in spontaneous ICH.

Homozygous sequestosome 1 (SQSTM1) mutation: a rare cause for childhood-onset progressive cerebellar ataxia with vertical gaze palsy.

Mutations in sequestosome 1 (SQSTM1) gene are associated with neurodegenerative diseases, such as frontotemporal dementia and amyotrophic lateral sclerosis. Recently, mutation in SQSTM1 was also found to cause a progressive childhood-onset cerebellar ataxia. We describe here a case of progressive childhood-onset cerebellar ataxia with vertical supra nuclear gaze palsy with no family history and a normal magnetic resonance imaging (MRI) of brain. The clinical exome sequencing in this patient showed a homozygous mutation in SQSTM1. This case highlights the importance of next-generation sequencing in the diagnosis of inherited ataxia syndromes. SQSTM1 mutation should be considered in the differential diagnosis in a patient with both cerebellar ataxia and ophthalmological manifestations.
