RESUMEN
Non-catheter related arterial thromboembolism in the neonatal population is rare and carries a significant risk of organ damage or limb loss. Thrombolysis, whether systemic or catheter- directed, is reserved either for limb or life-threatening thrombosis due to risk of bleeding especially in premature neonates. In this case, an infant male born at 34 weeks and 4 days gestational age presented with limb-threatening clot in the distal right subclavian artery and proximal right axillary artery with no known cause. After discussion of risks and benefits of various treatment options, he received thrombolysis treatment with low dose recombinant TPA via an umbilical artery catheter. There was complete resolution of the thrombus with this treatment and the patient had no significant bleeding while receiving treatment. Further investigation is needed to identify the patient population that will benefit from catheter-directed thrombolytic therapy and how to best monitor these patients.

This Viewpoint discusses the long-term medical, emotional, and financial implications of using amnioinfusion to treat anhydramnios; outlines the ongoing Renal Anhydramnios Fetal Therapy (RAFT) trial, which aims to document outcomes and survival in infants after amnioinfusion; and suggests that amnioinfusions be withheld in early anhydramnios, pending the findings of the RAFT trial.

Specific mutations in MECP2 cause Rett syndrome (RTT) in females whereas other mutations in the same gene cause several other syndromes in males, including X-linked intellectual disability (with and without spasticity) (OMIM 300055) and X-linked intellectual disability due to increased dosage of MECP2 (OMIM 300260). Males can also manifest an entity known as MECP2-related severe neonatal encephalopathy whose mutations are identical to those in females with RTT. We describe here the first case of MECP2-related severe neonatal encephalopathy caused by a mutation in exon one of MECP2, a mutation rarely identified in females with RTT. © 2016 Wiley Periodicals, Inc.

Objective: To evaluate recovery from neuromuscular blockade in infants using Train-of-Four nerve stimulation. Study Design: Ulnar nerve stimulation was used to evoke thumb twitch and reported as Train-of-Four ratio. Thumb twitch was also recorded visually in real-time. Primary outcome was time to near recovery of muscle function (Train-of-Four ratio >70%). Secondary analyses were time to greater degrees of recovery (Train-of-Four ratio >80, 90%), sensitivity of accelerometry vs. visual thumb-twitch and clinical variates to assess safety. Results: Patients were enrolled following rocuronium-boluses (n = 10) and vecuronium-infusions (n = 9). Median recovery time to Train-of-Four ratio >70% was 14 h following rocuronium-bolus dosing and 34 h following cessation of continuous vecuronium infusion. Median stimulus threshold for accelerometry was 27.5 mA and visual observation was 20 mA. There were no safety concerns. Conclusion(s): Neuromuscular monitoring using Train-of-Four nerve stimulation is feasible in infants. Some infants exhibited prolonged recovery from neuromuscular-blockade. These pilot data may facilitate future standardized pediatric protocols on neuromuscular monitoring for safer dosing.
