Relationship between maternal periodontal disease and Apgar score of newborns

PURPOSE: The aim of this study was to evaluate the relationship between maternal periodontal disease and the health status of newborns using Apgar scores. METHODS: One hundred pregnant women with periodontal disease were included in the case series and 100 pregnant women without periodontal disease were placed in the control group, respectively. The periodontal parameters of bleeding on probing (BOP), clinical attachment loss (CAL), probing depth (PD), birth weight, and Apgar scores were recorded in both groups. T-tests and Pearson's correlation coefficient were used to determine the birth weight odds ratio to analyze the relationship between the periodontal parameters of BOP, CAL, and PD on the one hand and an Apgar score of less than 7. An unpaired Student's t-test was used to analyze differences in means between the case and control groups using SPSS ver. 13. RESULTS: The means of the ages, periodontal pocket depths, attachment loss, areas with BOP, Apgar score in the first 5 minutes and infant birth weight exhibited statistically significant differences between the case and control groups. The ratio of an Apgar score of <7 to periodontal disease was 3.14; the ratio of low birth weight risk in mothers with periodontal disease to that in mothers without periodontal disease was 2.74. Pearson's correlation coefficient revealed a significant correlation between the infant birth weight and BOP, CAL, and PD of the mother. In addition, there was a significant correlation between the Apgar score and BOP, CAL, and PD and also between the Apgar score and infant birth weight. CONCLUSIONS: The results of this study showed a significant relationship between periodontal disease and infant birth weight; in addition, there was a significant relationship between the periodontal indexes of BOP, CAL, and PD on the one hand and the Apgar score on the other.

Postnephrectomy changes in doppler indexes of remnant kidney in unrelated kidney donors

We aimed to evaluate the intralobar renal arteries indexes using the Doppler ultrasonography indexes, which have become the established method of kidney monitoring, in living unrelated kidney donors during the postnephrectomy period. In this prospective study, we evaluated and followed up 34 living unrelated kidney donors. The Doppler ultrasonography indexes, including resistive index, pulsatility index, and peak systolic velocity, along with the grey-scale ultrasonographic indexes of cortical thickness, length, and anteroposterior diameter of the kidney were determined before nephrectomy, and then, 1 week and 3 months after nephrectomy. In addition, glomerular filtration rate were assessed simultaneously. The resistive index and pulsatility index did not change 1 week and 3 months after nephrectomy [P = .66 and P = .38, respectively]. The peak systolic velocity at 1 week was significantly higher than its prenephrectomy value [P = .02]. Also, the peak systolic velocity at 3 months was significantly higher than that prior to nephrectomy [P < .00 1]. Indexes of the kidney size all increased during the follow-up period. The estimated glomerular filtration rate increased decreased 1 week after nephrectomy, but it reach to a level comparable with its preoperative values after 3 months. Results of the present study showed an increased peak systolic velocity in association with unaltered resistive index and pulsatility index in the remnant kidney of donors, during the short-term follow-up. This finding indicates the increased blood flow and kidney size in the remnant kidney of donors, following nephrectomy
