    ABSTRACT: Aim of the present study was to evaluate the repeatability and reproducibility of the Doppler Resistive Index (R.I.) and the Ultrasound renal volume measurement in renal transplants. Twenty-six consecutive patients (18 men, 8 women) mean age of 42,8+/-12,4 years (M+/-SD) (range 22-65 years) were studied twice by each of two trained sonographers using a color Doppler ultrasound scanner. Twelve of them had a normal allograft function (defined as stable serum creatinine levels = or <123,76 micromol/L), whilst the remaining 14 had decreased allograft function (serum creatinine 132.6-265.2 micromol/L). Results were given as mean of 6 measurements performed at upper, middle and lower pole of the kidney. Intra- and interobserver variability was assessed by the repeatability coefficient and coefficient of variation (CV). Regarding Resistive Index measurement, repeatability coefficient was between 0.04 and 0.06 and the coefficient of variation was <5%. The analysis of the Student's t test did not show any significant difference between the measurements (t=0.15; p=0.87 n.s.). A good reproducibility was also detected in US measurements of renal length and volume. These results suggest that Color Doppler Resistive Index measurements of renal allograft and Ultrasound renal volume measurements are repeatable and reproducible.

    ABSTRACT: We investigated if nonnutritive sucking (NNS) during heelstick procedures alleviates behavioral distress in neonates. In our NICU, 26 neonates without severe complications (mean Minde score 0.8, range 0-3), undergoing heelstick procedures at least twice a day, in the first 2 weeks of life, were enrolled in the trial (mean gestational age 33.9 weeks, range 26-39 weeks, mean birth weight 1, 988.5 g, range 1,200-4,010 g, mean Apgar score at the first minute 6. 7, range 4-10, at the fifth minute 8.5, range 6-10). Two heelpricks were performed in each neonate with NNS randomly assigned. Behavioral states, transcutaneous oxygen tension (TcPO(2)), heart rate, and respiratory rate were monitored before, during and after the heelstick procedures. Heelstick procedures lasted for a mean of 109 s (range 50-230 s) with NNS, and a mean of 128.8 s (range 20-420 s) without NNS. Compared with baseline, heart rate and behavioral distress increased and respiratory rate decreased during heelstick and after heelstick. Oxygen tension did not change. Nonnutritive sucking had no effect on respiratory rate or transcutaneous oxygen tension, but reduced the time of crying and the heart rate increase during the procedure. In conclusion, NNS can be recommended to reduce distress in newborns undergoing invasive routine procedures. Further studies are needed to evaluate the effects of NNS on respiratory rate and blood gas levels.

    ABSTRACT: Objectives: The aim of this study is to asses weter the relationship between maternal dysphoria and duration of newborn spontaneous cry in the first days postpartum. Methods: 45 healthy newborns, born with a vaginal delivery from primiparous mothers were kept under observation in the nursery for at least 6h before being returned to their mothers and their cry was recorded by voice activated tape records. In the afternoon of the same day, mothers were interviewed and completed a standardized scale measuring the intensity of «Maternity Blues» (MBS) (Violani, et al. 1984). Results: Pearson correlation showed a relationship between the MBS score and the proportion of time spent crying by the newborns in the first day (r = .563 p < .000). Conclusions: Results indicate that there is a strong relationship between maternal mood and newborn spontaneous cry in the first hours of life.

    ABSTRACT: Objective: this study was done to investigate the magnitude of placental transfusion in cesarean section and to evaluate the influence of early and late cord-clamping on this transfusion. Methods: the infants in the study were selected from the healthy newborns nursery of the Division of Neonatology of University «Federico II» of Naples. We measured the hematocrit value of 74 newborns delivered at term by cesarean section, at birth and 72-96 hours of life. For all the comparisons we used the t-Test. Results: hematocrit values at 72-96 hours of life were significantly higher in comparison to the values at birth in both groups. The values of late clamped group at 72-96 hours of life were significantly higher in comparison to the early clamped group and the increase of the hematocrit during the first 72-96 hours of life was more marked in the late clamped group. The total bilirubin concentration at 72-96 hours of life didn't show significant differences between both groups. Conclusion: in conclusion placental transfusion takes place in cesarean section and delayed cord-clamping increases this transfusion.
