Clinical Outcomes in Children With Orbital Cellulitis and Radiographic Globe Tenting.

Purpose: Axial displacement of the globe with tenting centered on the optic nerve-globe junction is a predictor of visual loss in adults. The purpose of this study was to determine the visual outcomes of children with orbital cellulitis and globe tenting.

Methods: The records of 46 consecutive children with orbital cellulitis at a single tertiary children's hospital were reviewed retrospectively.

Random search is a behavioral strategy used by organisms from bacteria to humans to locate food that is randomly distributed and undetectable at a distance. We investigated this behavior in the nematode , an organism with a small, well-described nervous system. Here we formulate a mathematical model of random search abstracted from the connectome and fit to a large-scale kinematic analysis of behavior at submicron resolution.

Malignant Peripheral Nerve Sheath Tumor of the Lower Eyelid: Case Presentation and Literature Review.

Solitary benign neurogenic tumors are common in the orbit, but only rarely arise from peripheral nerves in the eyelids. In contrast, malignant tumors of neural or nerve sheath elements are exceedingly rare in the orbit and, to date, have never been reported in the lower eyelid. The authors report a 55-year-old man with multiple recurrent lower eyelid masses initially treated as chalazia then misdiagnosed as neurotropic malignant melanoma on pathology.

Dura splitting decompression for Chiari I malformation in pediatric patients: clinical outcomes, healthcare costs, and resource utilization.

Background: Dural splitting decompression may be an effective and safe treatment for Chiari I malformation.

Objective: To compare clinical outcomes, complications, and resource utilization for patients undergoing Chiari I decompression with or without duraplasty.

Methods: Between 2000 and 2009, the senior author performed 113 Chiari I decompression operations with dural splitting or duraplasty in children less than 18 years of age; 110 were included in a retrospective cohort analysis of safety, efficacy, and treatment cost.
