ABSTRACT
PURPOSE: We investigated whether there are independent intradaily changes in bilirubin levels in normal neonates. METHODS: During the period of January 1996 till July 1996, 100 healthy newborn infants were studied for at least 3 consecutive days. Starting from the third day of life, consistent intradaily changes of bilirubin concentration were observed. And obstetric history, birth history, weight change at 3 days were recorded from chart review. A complete blood cell count was obtained from each subject at the beginning of the study. RESULTS: The mean bilirubin concentrations at morning were 10.4 +/- 1.8mg/dl (3rd day), 11.6 +/- 2.1mg/dl (4th day) and 11.2 +/- 2.7mg/dl (5th day). The mean bilirubin concentrations at evening were 11.1 +/- 2.1mg/dl (3rd day), 11.3 +/- 2.2mg/dl (4th day) and 10.8 +/- 2.8mg/dl (5th day). Interdaily changes of bilirubin levels were found: morning levels were higher compared with those of the evening. CONCLUSION: We showed a consistent diurnal rhythm in bilirubin levels, with higher levels in the morning than in the evening. This diurnal rhythm in serum bilirubin concentration affects endogenous factors as well as exogenous. Mechanism of diurnal variation was unknown.

PURPOSE: We compared pathogen recovery rates by obtaining two blood cultures instead of one blood culture containing 1ml and collecting a larger volume, 1 to 3ml. METHODS: Total of 750 blood specimens from 250 patients with fever, a temperature higher than 39degrees C and suspected bacteremia were obtained. Each patient had two samples of blood, A (1ml) and B (4ml), obtained at 30-minute interval from separate sites of extremities and B was divided into B1 (1ml) and B2 (3ml). Each sample was inoculated into aerobic culture media. Patients were excluded if two samples of blood were not obtained or if the isolate represented a contaminant. RESULTS: A pathogen was isolated in 19 (7.6%) of 250 patients and 37 (4.9%) of 750 specimens. In 7 patients, the pathogen was isolated with all the culture methods and in 12 patients, one or more of the cultures yielded no growth. The pathogen recovery rates were 53% (10/19) in A and B1, 89% (17/19) in B2 and 68% (13/19) in A+B1. No difference was detected between A or B1 and A+B1 (P>0.05) and the pathogen recovery rate for B2 was significantly greater than that for A or B1 (P<0.05), but no significant differences were found in pathogen recovery when B2 was compared with A+B1. CONCLUSION: Increasing volume of blood from 1 to 3ml inoculated into blood culture bottles improves detection of bacteremia in pediatric patients and spares patients the cost and pain of an additional venipuncture.

Congenital atrichia is an anomaly characterized by congenital absence of hair in varying degrees as well as the ypopigmentation & poor development of the abnormal residual hair on the scalp, eyebrows, eyelashes & body. Two cases of congenital atrichia in siblings were reviewed. The first case was associated with congenital megacolon and skin biopsy of scalp (esp. parietal region) was non-specific. The second case was associated with bilateral inguinal hernia. Congenital atrichia is inherited by autosomal dominant or recessive. Acording to the limited pedigree data, our cases were X-linked recessive inheritance We report these cases with a review of related literatures.

The retrospective study was taken to study the serum transaminase level and it's correlation with several symptoms in human rotavirus gastroenteritis. 494 children, who admitted to the Department of Pediatrics in Dae Dong Hospital from January 1991 to December 1991 with chief complaints of waterdy diarrhea were included in studies. The 1st stool specimen on admission was tested for rotavirus Ag by ELLSA method. and than serum transaminase were checked. The results are as follows: 1) The peak incidence being between 6 months to 2 years in both group, but higher incidence was noted in Non-HRV group. Males are more common than females by ratio of about 2:1. 2) The major symptoms in order of frequency was diarrhea>dehydration>vomiting>coughing>fever in HRV group, diarrhea>dehydration=vomiting>fever>coughing in Non-HRV group. The incidence of dehydration and coughing in HRV group were higher than in Non-HRV group. 3) AST & ALT elevation above the normal value were 83.2% (213/256), 52.0% (133/256) in HRV group and 45.3% (116/238), 22.3% (57/238) in Non-HRV group. AST & ALT were significantly increased in HRV group than Non-HRV group (AST: p0.05, Non-HRV group: p>0.05). 6) Duration of diarrhea for 4-5 days & 1-3 days were relatively more common in HRV group than Non-HRV group. The frequency were 36.3% (93/256) in HRV group and 34.9% (83/268) in Non-HRV group. The degree of diarrhea were not correlated with serum transaminase level at each group (HRV group: p>0.05, Non-HRV group: p>0.05). 7) No fever or duration of fever for 1-2 days were relatively more common in both group. The frequency were 39.9% (102/256), 37.5% (96/256) in HRV group and 38.2% (91/238), 42.5% (101/238) in Non-HRV group. The degree of fever was not correlated with serum transaminase level in HRV group, but correlated with Non-HRV group (HRV group: p>0.05, Non-HRV group: p<0.05).
