Method: All 200 consecutive cases of neonates delivered at our hospital from March to August 2001 were included in this retrospective study. Temperatures were measured immediately after delivery, after 30 minutes, 1 hour, 2 hours, 8 hours and 15 hours and on the 2nd and 3rd day. Axillary temperatures ranging from 36.5 篊 to 37 篊 were regarded as normal. No cases of maternal fever or systemic infection of the newborns were discovered. All infants were discharged in good general condition. Results: The mean rectal temperature at birth was 37.19 篊. The lowest average temperature was reached at 1 hour after delivery (36.54 篊) with a significant difference between natural delivery (36.48 篊) and section (36.59 篊) (P<0.05). Temperature subsequently rose to 36.70 篊 at 8 hours and 36.78 篊 at 15 hours (P<0.05). Hypothermia was seen in 51.8% and hypothermia in 42.5% of the patients. On the 3rd day after delivery, 96% of all temperatures were in the normal range. A significant relation was found between hypothermia and both low birth weight (P<0.001) and low gestational age (P<0.05). Conclusion: The ref-erence range presently used did not include all physiological temperatures in the first 72 hours of life. Considering other factors, such as birth weight, route of delivery, gestational age and body temperature on the 2nd and 3rd day of life, may help to correctly assess the significance of temperatures beyond the reference range.展开更多

METHODS： Forty-one children with IHS and 46 healthy infants were examined by ultrasonography, and several hemodynamic indices such as peak systolic velocity （PSV） and resistant index （RI） of proper hepatic artery （PHA） were measured. Serum fibrosis markers including hyaluronic acid （HA）, pre-collagen type-Ⅲ （PC-Ⅲ）, collagen type Ⅳ （C-Ⅳ）, and laminin （LN） were assayed by radioimmunoassays. In children with IHS, liver tissues were obtained either by ultrasound-guided liver biopsy （n = 35） or in the course of operation （n = 6）. The stages of hepatic fibrosis were scored as mild （S1 and S2）, moderate （S3）, or severe （S4） according to liver histological diagnosis. Multiple groups comparative and Spearman correlative analyses were carried out. RESULTS： Histopathologically, 39 children （95.1%） were found to have hepatic fibrosis, 12 of them stage Sl or S2, 12 stage S3, and 15 stage S4. PSV, RI of the PHA, and serum HA showed a consecutive increase from mild to severe hepatic fibrosis and a close positive correlation with hepatic fibrosis in IHS group （r = 0.717, 0.745 and 0.712, respectively, P = 0.001）. The Doppler waveform of HV was also positively correlated with the degree of hepatic fibrosis in IHS group （r = 0.783, P 〈 0.001）.CONCLUSION： Combination of ultrasonic studies on the hepatic hemodynamics with the evaluation of serum HA may provide an indicator for hepatic fibrosis in patients with IHS, This may be a useful noninvasive method for the diagnosis and evaluation of the prognosis of IHS.展开更多

We report a Thai female infant who presented with progressive cholestatic jaundice since 1 mo of age, with normal serum y-glutamyltransferase. Immunohistochemical staining of the liver did not demonstrate BSEP along the canaliculi, while multidrug resistance protein 3 was expressed adequately. Novel mutations in ABCB11, a four-nucleotide deletion in exon 3, c.90_93delGAAA, and a single-nucleotide insertion in exon 5, c.249_250insT, were identified, with confirmation in her parents. These mutations were predicted to lead to synthesis of truncated forms of BSEP. Immunostaining and mutation analysis thus established the diagnosis of PFIC type展开更多
