Uterine artery doppler velocimetry in cases of perimenopausal bleeding

This study included 80 patients with perimenopausal bleeding, classified according to endometrium pathology, compared to 20 normal age-matching control group. Duplex transvaginal doppler velocimetry of the utretry was done for each participant, beside measurement of the endometrial thickness and the uterine volume. Our results show that the uterine artery S/D ratio and resistance index [RI], were significantly lower in the perimeopnpaual bleeding group, compared to the control group. The thickest endometrium was found in the endometrial hyperplasia group. Taking a cute off value of single layer endometrial thickness

Serum ferritin in cases of unexplained preterm labor

This study included 20 normal pregnant, and 20 patients with the diagnosis of unexplained labor. The gestational age ranged between 28 and 35 weeks. Serum ferritin was measured in each of the cases and controls. Our results show that there is a significantly lower level of serum among the cases of unexplained preterm labor, when compared to the control group. Current iron replacement therapy did not influence the results

Plasma atrial natriuretic peptide, renin activity, aldosterone sodium and potassium in normal and hypertensive pregnancy

To clarify a possible role for atrial naturiuretic peptide [ANP] in the pathophysiology of pregnancy complicated by hypertension, we studied plasma levels of ANP, Aldosterone, plasma rennin activity [PRA], sodium [Na+] and potassium [K+] in normal non pregnant women [n = 20], pregnant women with preeclampsia [n = 30] and in pregnant women with chronic hypertension [n = 12]. Plasma levels of ANP were found to be significantly increased in preeclamptic and chronic hypertensive women with the highest levels in the severe preeclampsia. On the other hand PRA, serum aldosterone and serum Na+ were found to be significantly reduced in severe preeclamptic and chronic hypertensive, pregnant women. An inverse relationship was found between plasma ANP and either serum aldosterone, PRA or serum Na+ in the severe preeclamptic and chronic hypertensive groups
