Aim To evaluate if broadening the criteria for retinopathy of prematurity (ROP) screening to include babies with gestational age ⩾32 weeks and/or birth weight ⩾1500 g, would have an impact on the number of babies diagnosed as having ROP. Methods A prospective cohort study was carried out at the Aga Khan University Hospital, Karachi, Pakistan. Infants with gestational age ⩽35 weeks or birth weight ⩽2000 g born in this hospital from May 2010 to December 2012 were screened for the presence of ROP 4-6 weeks after birth. Subsequent examinations were performed at intervals based on the findings of initial eye examinations. Infants diagnosed as having ROP were treated with argon laser therapy. Neonatal risk factors were also assessed. Cumulative incidence of ROP was calculated for babies falling within and outside current screening criteria. Multivariate logistic regression analysis was performed to examine the predictors of ROP. Results A total of 301 infants were screened: 27 (9%) babies developed ROP, of which 19 had stage 3 ROP or worse. None of the babies falling outside the current screening criteria developed ROP. The incidence of ROP in the infants meeting the current screening criteria was 11.5%. Multivariate logistic regression analysis showed that only gestational age (adjusted relative risk 0.774, 95% CI 0.603 to 0.994) was independently associated with the development of ROP. Conclusions In our population ROP was not seen to occur in infants older than 32 weeks gestational age and/or weighing more than 1500 g. [ABSTRACT FROM AUTHOR]

A patient was taken for emergent intra-arterial stroke therapy for an acute left middle cerebral artery stroke syndrome, with CT angiography showing a left internal carotid artery (ICA) occlusion. Through a 6 F Neuron MAX sheath, a 5 Max ACE Penumbra aspiration catheter was advanced to the thrombus and direct suction was performed through the ACE catheter and Neuron MAX sheath. Upon pull back, the thrombus became wedged in the Neuron MAX sheath and despite several attempts to aspirate the thrombus, no clot could be obtained. The Neuron MAX sheath was withdrawn to the left common carotid artery, and gently advanced to the origin of the external carotid artery (ECA). A glide wire was advanced and the thrombus dislodged into the ECA. Another pass with the 5 Max ACE was used to remove a remaining thrombus in the left ICA terminus, resulting in Thrombolysis in Cerebral Infarction (TICI) 3 flow. With improved devices for embolectomy, large and rigid emboli that exceed the inner diameter of large guide sheaths and balloon guide catheters can become lodged, and cannot be withdrawn through a catheter. While uncommon, strategies to overcome this are important to keep in mind during acute stroke intervention. [ABSTRACT FROM AUTHOR]
