The predictive power of endocrine tests for the diagnosis of polycystic ovaries in women with oligoamenorrhea.

Various hormonal parameters and the best logistic regression model to predict disease probability were evaluated in women with polycystic ovary syndrome (PCOS). Concentrations of LH, FSH, LH/FSH ratio, testosterone, free testosterone, SHBG and insulin in serum were recorded in 32 women with PCOS and in 25 controls. A model including LH/FSH ratio, insulin and testosterone measurements yielded the best goodness of fit for classification of women with and without PCOS in the logistic regression analysis.

Pyelocaliectasis and intrarenal artery doppler indices in uncomplicated pregnancies.

The effect of pyelocaliectasis on intrarenal arterial Doppler indices was evaluated in healthy pregnant women with respect to nonpregnant controls. There was no significant difference between the pregnant and nonpregnant subjects regarding the systolodiastolic ratio, resistivity index and pulsatility index throughout the second and third trimesters (p for all > 0.05).

Placental aging, fetal prognosis and fetomaternal Doppler indices.

Objective: To investigate the possible effects of the morphological changes in the placenta on fetal prognosis and on umbilical artery and uterine artery Doppler indices in late, low-risk pregnancies.

Study Design: Placental changes were evaluated ultrasonographically and pathologically in 224 pregnant women after the 25th gestational week. The placental morphology were graded ultrasonographically into five subgroups according to increasing severity of the changes.

Ultrasonographic dimensions of the vertical span of the fetal iliac bone and relationship with some fetal parameters.

Using fetal ultrasonography, disorders of developmental delay and congenital malformations are promptly diagnosed. Skeletal abnormalities are relatively easy to notice once standards of growth are established. The iliac bone is frequently affected in skeletal problems, yet it has not been extensively studied.
