Background: The aim of the study was to assess prospectively the evolution of multiple clinical parameters throughout the first trimester of pregnancy. Method: A transvaginal ultrasound examination and a blood test was weekly performed until the 13th gestational week in a group of healthy volunteers. A total of 25 spontaneously conceived singleton pregnant women with good pregnancy outcome finally completed the study. The evolution of 10 transvaginal ultrasound parameters, 5 Doppler measurements and 6 serum parameters was studied.Results: An increasing trend with advancing gestation was evident for the mean gestational sac (MSD) and amniotic sac (AS) diameters, trophoblastic rim, CRL and serum progesterone. The uterine, umbilical and fetal cerebral arteries PI decreased with advancing gestation. The FM yolk sac (YS) diameter and b-hCG levels showed an initial rise and a final decrease. A great interindividual variation was evident for the b-hCG titer. The YS/CRL progressively approached to 0, whereas the MSD/CRL and the AS/MSD progressively approached to 1. The corpus luteum diameter, corpus luteum arteries PI, subehorionic arteries PI, complement levels (C3 and C4), platelet count and activated partial thromboplastin time experienced minimal changes. Conclusion: First trimester normograms for multiple clinical parameters are provided. P02The first results of the ultrasound transvaginal screening in early pregnancies in Kazan city, Tatarstan, Russia In 1 January 2000 in order of Tatarstan Health Care Ministry transvaginal first trimester screening was introduced in Kazan city. All pregnant women have to be examined in one of 5 the medical centers.We present the results of six month screening for all pregnant women between 10 and 14 weeks gestation. Method: Routine transvaginal ultrasound examination included the measurement of fetal crown-rump length, nuchal translucency and estimation of fetal anatomy. Results: A total 1620 pregnant women of 10±14 weeks of gestation were examined from January till June 2000. All abnormalities were detected at the 12±13 weeks gestational ages. The increasing of nuchal translucency thickness were found in 23 cases, 7 of them chromosomal defects had, in this group in 5 cases cystic hygroma with hydrops were identified.In 12 cases structural anomalies were found: 1-body stalk anomaly, 1 case-omphalocele with liver in it, 1-holoprosencephaly with proboshisis and microphtalmia, 1-encephalocele, 3-acrania, 5-anencephaly. In the cases of holoprosencephaly and encephalocele nuchal translucency measured at 10±11 week was normal. Conclusion: Even the first results of early pregnancy transvaginal screening show its great significance in our city. The most adequate period for transvaginal screening is 12±13 weeks. P03The value of ultrasound screening for fetal abnormalities in the first trimester Objective: Evaluation of routine screening in the early pregnancy by transvaginal sonography (TVS) in an unselected population. Design and methods: A routine ultrasound examination was offered to ...
Amenorrhea can cause bone loss, but not all mechanisms in this process are known. The degree of bone loss in amenorrheic women is determined by the cause of the amenorrhea. The aim of this study was to investigate the influence of secondary amenorrhea on bone density and to compare the bone density between hypogonadotropic amenorrheic women and hypergonadotropic amenorrheic women. Twenty-two amenorrheic and 12 eumenorrheic women under the age of 40 were involved in this study. Every woman underwent measurements of lumbar spine and femoral neck bone density, body mass index (BMI), and serum levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol, progesterone, and prolactin. According to FSH levels, we divided the women with amenorrhea into two groups: hypergonadotropic (n = 7; FSH, >40 IU/l) and hypogonadotropic (n = 15; FSH, < or =40 IU/l) amenorrheic women. Amenorrheic women had a lower lumbar spine bone density than eumenorrheic controls (P = 0.002). Hypergonadotropic amenorrheic women had lower lumbar spine bone density (P = 0.026) than hypogonadotropic ameneorrheic women. In the hypergonadotropic group, only FSH level had a correlation (negative) with lumbar spine bone density (P = 0.05), but in the hypogonadotropic group, there was no correlation between hormonal levels, BMI, age, or duration of amenorrhea. BMI was positively correlated with lumbar spine bone density in amenorrheic women (P < 0.025). Amenorrheic women had lower bone density than eumenorrheic women, but hypergonadotropic amenorrheic women had lower bone density than hypogonadotropic women. The greater bone loss in the hypergonadotropic amenorrheic group could have been caused by a potential direct effect of FSH on bone metabolism.
It is widely accepted that menopause leads to changes in hormonal status, metabolism and lipid profile. The aim of this study was to analyze the influence of menopause on the concentrations of lipids, lipoproteins and, the influence of estradiol, progesterone, FSH, LH on lipid profile in menopausal women as well. The menopausal women had higher but non-significant (p>0,05) concentrations of total cholesterol, VLDL, LDL, and triglycerides than women with regular menstruation. The concentration of HDL was significantly lower in menopausal women than in women with regular menstruation (p<0,05). Also, the concentration of apolipoprotein B was significantly higher in menopausal women (p<0,05), but the concentrations of apolipoprotein and lipoprotein (a) were lower but without significance (p>0,05). Estrogen concentration has significant negative correlation with VLDL and triglycerides (p<0,05) and significant positive correlation with HDL (p<0,05) in menopausal women. Progesterone concentration has shown no correlation with concentrations of lipids and lipoproteins in menopause. We can conclude that menopause leads to changes in lipid profile by reducing HDL, and elevating apolipoprotein B levels, thus increasing the risk for cardiovascular disease. These changes were caused by reduction of estrogen concentrations in menopause.
Our results indicate that measuring PIBF and cytokine concentrations in serum during pregnancy is feasible and may be important for understanding immunological causes of pre-term delivery.
There is no correlation between the age of menarche occurrence, parity and age of the menopause.
