RESUMO
BACKGROUND: Time to revascularization is critical in improving outcomes in stroke thrombolysis. We studied the effectiveness of a mobile app based strategy to improve door-to-needle time (DNT) in treatment of acute ischemic stroke. METHODS: Consecutive patients presenting with acute ischemic stroke to the emergency department at a tertiary care hospital in Southern India between April 2017 - September 2018 were included. The app enabled rapid entry of patient parameters, the NIH stroke scale (NIHSS), thrombolysis checklist and dose calculation along with team synchronization, notifying all on-call members and team leaders of the patient movement, and sharing of radiological images. DNT captured from the app was compared to previous values from our center using one-way Analysis of Variance (ANOVA) after adjusting for differences in baseline variables. RESULTS: A total of 76 patients were thrombolysed during the study period, while using the mobile app. The mean DNT was 41 min, with 89% being thrombolysed within 60 min and 57% being thrombolysed within 45 min. Compared to 100 consecutive patients thrombolysed in the months prior to April 2017 where the mean DNT was 57 min, with 67% thrombolysed within 60 min and 47% being thrombolysed within 45 min, there was a mean DNT decrease of 16 min with 1.3x increase in DNT < 60 min. This difference was statistically significant after adjusting for age, sex and NIHSS Score (p=0.005, One-Way ANOVA). CONCLUSION: We have been able to demonstrate a significant improvement in DNT using mobile app as a tool to improve team performance.

Accelerated gait decline in aging is associated with many adverse outcomes, including an increased risk for falls, cognitive decline, and dementia. Yet, the brain structures associated with gait speed, and how they relate to specific cognitive domains, are not well-understood. We examined structural brain correlates of gait speed, and how they relate to processing speed, executive function, and episodic memory in three non-demented and community-dwelling older adult cohorts (Overall N = 352), using voxel-based morphometry and multivariate covariance-based statistics. In all three cohorts, we identified gray matter volume covariance patterns associated with gait speed that included brain stem, precuneus, fusiform, motor, supplementary motor, and prefrontal (particularly ventrolateral prefrontal) cortex regions. Greater expression of these gray matter volume covariance patterns linked to gait speed were associated with better processing speed in all three cohorts, and with better executive function in one cohort. These gray matter covariance patterns linked to gait speed were not associated with episodic memory in any of the cohorts. These findings suggest that gait speed, processing speed (and to some extent executive functions) rely on shared neural systems that are subject to age-related and dementia-related change. The implications of these findings are discussed within the context of the development of interventions to compensate for age-related gait and cognitive decline.

INTRODUCTION: Obstructive sleep apnoea (OSA), is characterized by loud snoring and excessive daytime sleepiness. Though the gold standard for diagnosis is overnight polysomnography (PSG), sleep questionnaires have also been used to diagnose this with good predictive value. MATERIAL AND METHODS: A pre-designed proforma with clinical details, symptom-specific questions for diagnosis of OSA, and Epworth Sleepiness Scale (ESS) was administered to 20 patients presenting to the Sleep Disorder Clinic of our hospital and to 40 age and sex-matched relatives (control group). The students 't-test' and chi-square were used as the statistical tests. RESULTS: There were 20 patients with a mean age of 41+/- 8 years, and 40 controls with a mean age of 41 +/- 6 years (P=>0.05). Seven had family history of snoring in the study group and 3 in the control group (P=0.02). Four had met with road traffic accidents in the study group and none in the control group (P=0.001). The body mass index (BMI) was 29.9 (SD 4.4) in the study group and 24.5 (SD3.5) in the controls (P=0.001). The mean ESS was 13.3 +/- 6 in the patients and 4.2+ 4 in the controls (P=0.001). A larger number of patients with OSA had hypertension: 5/20 vs. 3/40 (P=0.01). CONCLUSION: Patients with OSA had significantly higher BMI and ESS score, and were more likely to have hypertension and road traffic accidents. Increased awareness of this entity is essential.

Leukoencephalopathy, intracranial calcifications, and cysts (LCC) is a very rare cerebral disorder, first described in 3 children in 1996. It has subsequently been reported in adults and children from Europe and America, but has not so far been reported from Asia. We report an adult patient with pathologically proven LCC from a tertiary care hospital in South India. He presented with features of ataxia and raised intracranial pressure. Magnetic resonance imaging of the brain showed multiple bilateral cerebral cystic lesions along with diffuse white matter lesions in the cerebral and cerebellar white matter, and computed tomography of brain showed multiple calcifications in the white matter and basal ganglia. A large right cerebellar cyst causing mass effect was surgically excised. Histopathologic features were consistent with earlier reports of LCC and showed Rosenthal fibers, angiomatous changes, and calcifications. Our report suggests that although it is rare, LCC has a global distribution.
