Effect of Otitis Media and Cerumen Occlusion on Body Temperature Measured by Thermometers / 소아감염

PURPOSE: To examine the effect of unilateral otitis media and unilateral cerumen occlusion of the ear canal on thermometers. METHODS: One hundred eighty six children with unilateral otitis media, fifty children with unilateral cerumen occlusion, and fifty children with neither otitis media nor cerumen were enrolled. Temperature was measured in both ear canals using thermometers. After 15 minutes, second temperature was measured again in both ears. Unilateral otitis media was graded by video otoscope for 7 grades. Differences in temperatures between affected ears and unaffected ears were analyzed. RESULTS: No temperature difference between the normal and cerumen groups was observed. The mean temperature of the otitis media ear canal was 0.13+/-0.20degrees C higher than that of the intact ear canal (36.99+/-0.54degrees C vs 36.86+/-0.52degrees C; P<0.001). There was no statistically significant temperature difference between grades. CONCLUSION: Unilateral otits media can affect estimation of body temperature measured by thermometers.

Clinical Spectrum of Norovirus Gastroenteritis Compared to Rotavirus Gastroenteritis at a Single Center in Gwanju, Korea during 2005-2006; Compared to Rotaviral Gastroenteritis / 소아감염

PURPOSE:We evaluated the clinical features of Norovirus gastroenteritis compared with Rotavirus gastroenteritis in hospitalized children. METHOD:We detected causative agents in 3,261 samples of children hospitalized with gastroenteritis symptoms at a single center of pediatrics between 2005 and 2006. Among 266 and 303 samples which tested positive for Norovirus and Rotavirus, we selected 73 and 182 samples of children with relatively pure gastroenteritis symptoms and retrospectively analyzed the corresponding medical records. RESULTS:The male-to-female ratio of the Norovirus (+) and Rotavirus (+) groupswas 1.43:1 and 1.56:1 both groups were predominantly in males. The mean age of the Norovirus (+) and Rotavirus (+) groups was 36.7 and 24.4 months, respectively the children in the former group were older than the children in the latter group. The incidence in the Norovirus (+) group was more concentrated in the winter. The symptoms in the Norovirus (+), in decreasing order, included vomiting, diarrhea, and fever. The duration of vomiting, diarrhea, and fever was 2.1, 1.2, and 1.2 days. The maximum number of episodes of vomiting and diarrhea per day was 3.5 and 4.5, respectively. The severity score was 10.16. The symptoms inthe Rotavirus (+) group, in decreasing order, included diarrhea, vomiting, and fever. The duration of diarrhea, vomiting, and fever was 2.2, 4.3, and 2.2 days, respectively. The maximum number of episodes of vomiting and diarrhea per day was 3.3 and 6.5, respectively. The severity score was 11.9. The severity in the Norovirus (+) group was somewhat lower than the Rotavirus (+) group. The younger the child, the more severe the symptoms in the Norovirus (+) group. There was no difference between mono-and co-infection in severity and between the two groups regarding the hematologic findings. CONCLUSION:Based on the findings reported herein, additional studies about prophylaxis, as well as the epidemiology and clinical features of pediatric Norovirus gastroenteritis, are required.
