Rapid antigen detection testing (RADT) is often performed for diagnosis of group A beta-hemolytic streptococcal (GABHS) pharyngitis among children. Among adults, the sensitivity of this test varies on the basis of disease severity (spectrum bias). A similar phenomenon may occur when this test is used in a pediatric population, which may affect the need for culture confirmation of all negative RADT results. ⋯ The sensitivity of RADT for GABHS pharyngitis is not a fixed value but varies with the severity of disease. However, even among pediatric patients with > or =3 Centor criteria for GABHS pharyngitis, the sensitivity of RADT is still too low to support the use of RADT without culture confirmation of negative results.

Comparative Study
Children should wear helmets while ice-skating: a comparison of skating-related injuries.
This study compares injuries, especially head injuries, among ice-skaters with those among skateboarders, rollerskaters, and in-line skaters, to determine the need for helmet use during recreational ice-skating by children. ⋯ The proportion of head injuries among ice-skaters in this study was greater than that observed for participants in other types of skating, for which helmet use is recommended and often required. Children should wear a helmet during recreational ice-skating. Mandatory helmet use by pediatric ice-skaters at indoor rinks should be implemented. Use of other types of protective equipment, such as wrist guards, knee pads, and elbow pads, should be considered for prevention of injuries to the extremities during ice-skating. Caution should be used when allowing young children to participate in recreational ice-skating. Additional research should be conducted in other populations, to corroborate these findings and to evaluate ice-skating safety recommendations for children.

Stress systems may be altered in the long term in preterm infants for multiple reasons, including early exposure to procedural pain in neonatal intensive care. This question has received little attention beyond hospital discharge. Stress responses (cortisol) to visual novelty in preterm infants who were born at extremely low gestational age (ELGA; < or =28 weeks), very low gestational age (VLGA; 29-32 weeks), and term were compared at 8 months of age corrected for prematurity (corrected chronological age [CCA]). In addition, among the preterm infants, we evaluated whether cortisol levels at 8 months were related to neonatal exposure to procedural pain and morphine in the neonatal intensive care unit. ⋯ ELGA preterm infants show a different pattern of cortisol levels before and after positive stimulation of visual novelty than more maturely born, VLGA preterm and term-born infants. Exposure to high numbers of skin-breaking procedures may contribute to "resetting" basal arousal systems in preterm infants.
