• Agreement between the temporal artery scanner, digital oral thermometer, and infrared tympanic thermometer calibrated to an oral setting in pediatric patients who are febrile and afebrile [ Designated as safety issue: No ]
  

• Similarities or differences in the percent of fevers detected with oral, ear, and temporal artery monitoring [ Designated as safety issue: No ]
  
• Differences in agreement of the various temperature devices [ Designated as safety issue: No ]
  

OBJECTIVES:

Primary

• Determine agreement between three different types of temperature-measuring instruments: the temporal artery scanner, the digital oral thermometer, and the infrared tympanic thermometer calibrated to an oral setting, in pediatric patients who are febrile and afebrile.

Secondary

• Determine similarities or differences in the percent of fevers detected with oral, ear, and temporal artery monitoring in these pediatric patients.
• Determine differences in agreement of the various temperature devices in non-neutropenic pediatric patients versus neutropenic pediatric patients.

OUTLINE: This is a prospective study.

During an afebrile episode, the patient's temperature is measured twice using the following 3 devices: a temporal artery scanner, a digital oral thermometer, and an infrared tympanic thermometer calibrated to an oral setting (total of 6 temperature measurements per afebrile episode).

During a febrile episode, the patient's temperature is measured twice using all 3 devices as above, and then at 2 and 4 hours after administration of an antipyretic medication (total of 18 temperatures per febrile episode).

Patients' temperatures are recorded for a maximum of 3 afebrile or febrile episodes.

PROJECTED ACCRUAL: A total of 32 patients will be accrued for this study.
