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.

Article Synopsis
  • - Posterior reversible encephalopathy syndrome (PRES) is a temporary brain condition often triggered by factors like high blood pressure, eclampsia, certain medications, or kidney failure, primarily affecting the brain's posterior circulation.
  • - A case study describes a young woman who experienced sudden, painless vision loss after childbirth, linked to PRES affecting her lateral geniculate body, which is part of the visual pathway.
  • - MRI results confirmed the diagnosis, and she recovered after 5 days with proper blood pressure management, highlighting the reversibility of PRES when treated promptly.

The patient being reported is a middle-aged man who developed isolated facial nerve palsy and was initially treated as Bell's palsy. However, on MRI of the brain, he was found to have pontine haemorrhage.

Pontine hemorrhages are relatively uncommon. Various atypical manifestations of pontine stroke like eight-and-a-half syndrome, fifteen-and-a-half syndrome, and sixteen syndrome have been described in the past. We came across a case of pontine bleed that presented with bilateral facial palsy, bilateral horizontal gaze palsy, and contralateral sensorineural hearing loss accounting to the hitherto not described "twenty-four syndrome" with Horner's syndrome and left hemiparesis.

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.
