Randomized Controlled Trial Multicenter Study Comparative Study
Needle-free powder lidocaine delivery system provides rapid effective analgesia for venipuncture or cannulation pain in children: randomized, double-blind Comparison of Venipuncture and Venous Cannulation Pain After Fast-Onset Needle-Free Powder Lidocaine or Placebo Treatment trial.
The Comparison of Venipuncture and Venous Cannulation Pain After Fast-Onset Needle-Free Powder Lidocaine or Placebo Treatment trial was a randomized, single-dose, double-blind, phase 3 study investigating whether a needle-free powder lidocaine delivery system (a sterile, prefilled, disposable system that delivers lidocaine powder into the epidermis) produces effective local analgesia within 1 to 3 minutes for venipuncture and peripheral venous cannulation procedures in children. ⋯ The needle-free powder lidocaine delivery system was well tolerated and produced significant analgesia within 1 to 3 minutes.

Randomized Controlled Trial Multicenter Study
Absence of an increase in cardiorespiratory events after diphtheria-tetanus-acellular pertussis immunization in preterm infants: a randomized, multicenter study.
The American Academy of Pediatrics recommends immunization of preterm infants at 2 months' chronological age with diphtheria-tetanus-acellular pertussis vaccine, regardless of birth weight and gestational age. Several investigators have reported an increased incidence of cardiorespiratory events in preterm infants after immunization. Consequently, many primary care providers do not adhere to American Academy of Pediatrics guidelines. The purpose of this study was to reexamine the relationship between diphtheria-tetanus-acellular pertussis and cardiorespiratory events in preterm infants by using a random control study design and an objective assessment of cardiorespiratory events. ⋯ Preterm infants who received diphtheria-tetanus-acellular pertussis at 2 months after birth were no more likely to experience prolonged apnea and bradycardia than were control infants. This study supports the American Academy of Pediatrics recommendation regarding diphtheria-tetanus-acellular pertussis immunization at 2 months of age for preterm infants.

Randomized Controlled Trial
Effect of low-dose naloxone infusion on fentanyl requirements in critically ill children.
Sedating critically ill patients often involves prolonged opioid infusions causing opioid tolerance. Naloxone has been hypothesized to limit opioid tolerance by decreasing adenylate cyclase/cyclic adenosine monophosphate activation. The study purpose was to investigate the effect of low-dose naloxone on the maximum cumulative daily fentanyl dose in critically ill children. ⋯ We conclude that administration of low-dose naloxone (0.25 microg/kg per hour) does not decrease fentanyl requirements in critically ill, mechanically ventilated children.

Fibrodysplasia ossificans progressiva is a rare and disabling genetic condition characterized by congenital malformation of the great toes and by progressive heterotopic ossification in specific anatomic patterns. Most patients with fibrodysplasia ossificans progressiva are misdiagnosed early in life before the appearance of heterotopic ossification and undergo diagnostic procedures that can cause lifelong disability. Recently, the genetic cause of fibrodysplasia ossificans progressiva was identified, and definitive genetic testing for fibrodysplasia ossificans progressiva is now available before the appearance of heterotopic ossification. ⋯ Clinical suspicion of fibrodysplasia ossificans progressiva early in life on the basis of malformed great toes can lead to early clinical diagnosis, confirmatory diagnostic genetic testing, and the avoidance of additional harmful diagnostic and treatment procedures. This is the first report of genetic confirmation of fibrodysplasia ossificans progressiva before the appearance of heterotopic ossification. Pediatricians should be aware of the early diagnostic features of fibrodysplasia ossificans progressiva, even before the appearance of heterotopic ossification. This awareness should prompt early genetic consultation and testing and the institution of assiduous precautions to prevent iatrogenic harm.

Bedside emergency ultrasound has been used by emergency physicians for >20 years for a variety of conditions. In adult centers, emergency ultrasound is routinely used in the management of victims of blunt abdominal trauma, in patients with abdominal aortic aneurysm and biliary disease, and in women with first-trimester pregnancy complications. ⋯ As the modality advances and becomes more available, it will be important for primary care pediatricians to understand its uses and limitations and to ensure that pediatric emergency physicians have access to the proper training, equipment, and experience. This article is meant to review the current literature relating to emergency ultrasound in pediatric emergency medicine, as well as to describe potential pediatric applications.
