Infantile myofibromas obstructing opposite ends of the gastrointestinal tract.

Myofibromas are benign congenital tumors of soft tissue that can present at birth or during infancy in solitary or multicentric forms. Visceral myofibromas are rarely reported, but are typically symptomatic due to involvement of vital structures. We present two cases of congenital myofibromas, one obstructing the proximal esophagus and the other obstructing the distal rectum. Lessons learned from the treatment of these two patients are shared and the pertinent literature is reviewed.

Evaluation of a new pediatric intraosseous needle insertion device for low-resource settings.

BACKGROUND AND PURPOSE: The Near Needle Holder (NNH) (Near Manufacturing, Camrose, Alberta, Canada) is a reusable tool to introduce a standard hollow needle for pediatric intraosseous (IO) infusion. We compared the NNH to the Cook Dieckmann (Cook Critical Care, Bloomington, IN) manual IO needle in a simulation setting. METHODS: Study subjects were 32 physicians, nurses, and medical students participating in a trauma course in Guyana. After watching a training video and practicing under supervision, subjects were observed inserting each device into a pediatric leg model using a randomized crossover design. Outcome measures were time to successful insertion, technical complications, ease of use, and safety of each device. RESULTS: The mean time for IO insertion (32 ± 13 seconds) was similar for both devices (P = .92). Subjects rated the NNH device equivalent in ease of use to the Cook IO needle but slightly lower in perceived safety to the user. CONCLUSIONS: After training, all subjects successfully inserted the NNH IO device in a simulation environment, and most rated it as easy to use and safe. The NNH is a significant advance because IO needles are often not available in emergency departments in developing countries. Further studies are needed to evaluate clinical effectiveness of the NNH.
