Three Cases of Subacute Necrotizing Lymphadenitis in Childhood

Subacute necrotizing lymphadenitis was first reported by Kikuchi and Fujimoto in 1972. Young females no more than 30 years of age are mainly affected. It usually manifests as fever and cervical lymphadenopathy. We experienced three cases of subacute necrotizing lymphadenitis in an 11-year-old boy, a 12- year-old boy and an 11-year-old girl. Symptoms presented were URI signs, diarrhea, headache and weight loss along with fever and cervical lymphadenopathy. Fever persisted from 9 to 30 days and did not respond to antibiotics. We performed aspiration biopsy of cervical lymph node which was consistent with subacute necrotizing lymphadenitis in all cases. We used oral steroid in one case. Fever and lymphadenopathy subsided spontaneously within one month. There were no other complications.

A Study of Reliability of Tympanic Temperature Measurement Using Infrared Thermometer ( Home Model ) in Neonates

PURPOSE: Taking an accurate and rapid body temperature can give a valuable information when taking care of neonates. The purpose of this study is to compare the reliability of taking rapid and less complicated means of measuring body temperature at tympanic membrane by infrared tympanic thermometer(Thermoscan IRT 1020, type 60005711, home model) with the standard method of taking body temperature at axilla and rectum by mercury thermometer. METHODS: Simultaneous rneasurements of tympanic membrane and axillary temperatures were taken followed by rectal temperatures within 5 minutes by 2 different investigators from 107 term infants One investigator measured tympanic membrane temperature by infrared tyrnpanic thermometer for 3 times and took the highest temperature as a final measurement and the other investigator took the axillary temperature for at least 5 minutes and rectal temperature for at least 2 minutes on each patient. RESULTS: Total of 107 term infants including 57 males and 50 females were subjects, The average body temperatures were 36.7+/-0.3degree, 37.0+/-0.4degree, 36.6+/-0.3degree for axillary, reactal and tympanic membrane, respectively. The correlation coefficients between axillary, rectal and tympanic temperature measurements were high at r=0.746- 0.804 and were statistically significant at P<0.001. CONCLUSION: We have shown from this study that taking tympanic membrane temperature can be used as an altemative and reliable means of taking body temperature in place of taking axillary and rectal temperature in neonates.

The Percentiles of Body Mass Index and Trend of Obesity in Schoolage Children in Seoul

PURPOSE: Many authors have reported that obesity is a serious health problem in schoolage children and adolescents and recently obese children are increasing. Accurate diagnosis is needed to estimate the prevalence rate and trend of obesity. We studied body mass index(BMI) percentile for age and sex as a reliable and valid screening for adiposity. METHODS: We measured weight and height of 33,329 schoolage children to estimate obesity according to body mass index(weight in kilograms/height in meters2) and different standard weight. We also calculated BMI percentiles according to age and sex. We defined obesity for screening purposes as body mass index(BMI) equal to or in excess of the 95th percentile for age and sex. We also compared the prevalence of obesity according to a different standard weight. RESULTS: The mean value of body mass index(BMI) increases with age and tends to be slightly higher for male than female subjects. The 95th percentiles of body mass index(BMI) ranges from 18.9kg/m2 to 28.2kg/m2 for both males and females. No significant differences were apparent in the mean value of body mass index for each year. CONCLUSION: The percentile curves of body mass index(BMI) will help pediatricians to determine the relative ranking of patients compared with large sample of healthy schoolage children. Further studies are needed to define a useful criteria for defining obesity using body mass index(BMI) in childhood and adolescence. A longitudinal study and nationwide sampling will be required to overcome the limitation of this cross-sectional study.

A Case of Hemolytic Disease of the Newborm due to Anti - Dib Antibody

The Diego blood group system consists of two pairs of antigens, Dia and Dib The incidence of Dia is low among pure Caucasian, Blacks, Polynesian and Eskimo, however, the rnongolians and American indians have both Dia and Dib. We report a case of two days old male who was admitted on first day of life for jaundice and subsquently exchange transfusion was performed on second day of life for bilirubin of 20 mg/dl. The blood groups of patient and his mother were both Rh D positive 0 type. Direct and indirect Coombstest were strong positive in the patient and indirect Coombstest was positive in his mother. We found anti-Dib antibody in his rnother's serum. The phenotype of Diego blood group system of the patient and his mother were Di (a+b+) and Di (a+b- ), respectively and hemolytic anemia in this case was due to anti-Dib antibody.
