Mobile App Based Strategy Improves Door-to-Needle Time in the Treatment of Acute Ischemic Stroke.

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.

Dissecting an Outbreak: A Clinico-epidemiological Study of Nipah Virus Infection in Kerala, India, 2018.

BACKGROUND: An outbreak of Nipah virus infection was confirmed in Kerala, India in May 2018. Five out of 23 cases including the first laboratory-confirmed case were treated at Baby Memorial Hospital (BMH), Kozhikode. The study describes the clinical characteristics and epidemiology of the Nipah virus outbreak at Kozhikode during May 2018. OBJECTIVE: To study the clinical and epidemiological profile of Nipah virus epidemic that occurred in Kerala in May 2018. METHODS: A collaborative team of physicians and epidemiologists from BMH, Medical College Hospital (MCH) Kozhikode and from the Indian Medical Association (IMA) conducted this study. The clinical and exposure history and the data on outbreak response were gathered from hospital medical records and through interviewing patient relatives and health workers using questionnaires. RESULTS: It was identified that out of the 23 patients with Nipah virus infection, 21 (91.3%) expired. Out of the 21 patients, 18 tested positive for Nipah virus by Real Time polymerase chain reaction (RT-PCR). It has been found that only the index case was infected in the community from fruit bats. Rest of the cases were due to transmission of the virus at three public hospitals. Median age was 45 years. 65% of them were males. Median incubation period was 9.5 days. Fever (100%), altered sensorium (84.2%), tachycardia (63.1%), hypertension (36.8%), segmental myoclonus (15.7%), segmental sweating (15.7%) and shortness of breath (73.6%) were common features. Mean duration of illness was 6.4 days. CONCLUSION: The rapid spread of infection uncovered the miserable state of health care system in implementing infection control measures. The case fatality and the socio-economic burden warrant developing appropriate treatments, vaccines and diagnostics.

Bilateral lateral geniculate body lesions causing reversible blindness in a patient with posterior reversible encephalopathy syndrome.

Posterior reversible encephalopathy syndrome (PRES) is a completely reversible neuroradiological entity caused by accelerated hypertension, eclampsia, certain cytotoxic drugs and acute renal failure. PRES involves posterior circulation of the brain resulting in various manifestations, hence the name. Acute vision loss is one of the manifestations that occurs owing to the involvement of the visual pathway. However, loss of vision due to a lesion involving the lateral geniculate body alone is unusual. We report one such case of a young female who developed acute bilateral painless loss of vision without any other symptom during postpartum period. MRI brain showed features of PRES involving bilateral lateral geniculate body, hippocampus and brainstem. There was no involvement of retrogeniculate visual pathway, i.e. parieto-occipital cortex. The patient improved with optimal blood pressure control and was discharged after 5 days.

Intracranial hypertension with polyradiculopathy--early CSF diversion to optimize neurological recovery.

Cerebral venous sinus thrombosis (CVST) and idiopathic intracranial hypertension (IIH) are common considerations in young patients presenting with isolated intracranial hypertension. We report two patients with progressive visual failure and polyradiculopathy with areflexic quadriparesis, secondary to raised intracranial pressure (ICP). Both underwent cerebrospinal fluid diversion with complete recovery. Such a fulminant presentation of raised ICP with an excellent outcome has rarely been reported in the literature.
