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.

Serum tumor markers in chronic liver disease.

Tumor markers have been used for the evaluation of various malignancies though the existence of false positive results in some benign diseases is known. In this study, several established markers including carcinoembryonic antigen, alpha fetoprotein, beta human chorionic gonadotropin, ferritin, CA 19-9 and CA 125 were measured in 60 patients with chronic active hepatitis, 70 patients with cirrhosis and 40 normal subjects in order to evaluate the rate of false elevation of tumor markers in chronic liver disease. Prostate specific antigen and prostatic acid phosphatase levels were also measured in male patients and controls.

Transverse cerebellar diameter and transverse cerebellar diameter/ abdominal circumference index for assessing fetal growth.

In a prospective study of 330 pregnant women, measurements of the transverse cerebellar diameter (TCD), abdominal circumference (AC), biparietal diameter (BPD), head circumference (HC) and TCD/AC ratio and HC/AC ratio were obtained using conventional ultrasonography between 16th and 41st weeks of gestation. Measurement of BPD yielded a strong correlation with gestational age (r = 0.9880 and R2 = 0.

Periumbilical skin length measurements in the newborn.

Normal limits of periumbilical skin were determined in 304 newborn babies in the first 24 h. Cranial umbilical skin (SD) was 12.36 (3.

Scapula length measurement for assessment of fetal growth and development.

To determine the value of prenatal ultrasonographic scapula measurements for fetal growth and development as an adjunct to assessing in utero development, a prospective study of ultrasonography was conducted in 343 pregnant women with uneventful pregnancies with gestational ages from 16 to 41 weeks, and several biometric measurements were obtained. The relationships of scapula length with gestational age and with biparietal diameter, femur length, abdominal circumference and scapula length were examined. With the ultrasonographic examinations of 343 healthy pregnant women, a nomogram of scapula length measurements estimating gestational age and predicting the biparietal diameter, abdominal circumference, and femur length was generated.

Lactational failure--study of risk factors in Turkish mothers.

Risk factors for lactational failure in puerperium were investigated. Sixty mothers with inadequate daily milk supply for their babies were the lactational failure group, and 60 mothers with similar age having babies with similar age and weight were chosen as the control group. Low prolactin levels, low serum iron and low serum ferritin levels and low aldosterone values and birth in community hospitals were associated with significantly increased risk of deficient lactation.

Umbilical artery blood flow characteristics in normal pregnancies.

585 pregnant women were investigated with both conventional sonographic examination and color Doppler examination. The cases with intrauterine growth retardation, preeclampsia, twin pregnancies, congenital malformations and diabetes were excluded. The remaining 550 cases (between ages 16 and 40) were investigated in the first trimester and gestational ages were compatible with the last menstrual date.

Plasma chromium levels in hypoglycemic preterm, full-term and in intrauterine-growth-retarded babies.

Serum chromium levels of hypoglycemic preterm and full-term babies were investigated. Normoglycemic preterm and full-term babies were selected as the control group. There was no statistically significant difference in serum Cr levels between preterm and full-term, hypoglycemic and normoglycemic, preterm hypoglycemic and preterm normoglycemic, full-term hypoglycemic and full-term normoglycemic babies.

Short course intermittent chemotherapy in childhood tuberculosis.

A total of 130 children diagnosed as having pulmonary and extrapulmonary tuberculosis who received short course intermittent chemotherapy between 1978-1992 were evaluated retrospectively. One hundred and ten children with tuberculosis were treated with isoniazid (10-15 mg/kg, maximum 400 mg), rifampin (10-15 mg/kg, maximum 600 mg), and streptomycin (30 mg/kg, maximum 1 g) daily, for 15 days. Treatment was completed with similar doses of isoniazid and rifampin twice a week for a period of 9 months.

Tuberculous spondylitis and intermittent chemotherapy in childhood.

The general characteristics and treatment of childhood tuberculous spondylitis are reviewed. Most of the patients (79 per cent) were under 5 years old with girls being in greater number. Twenty-six patients used classical antituberculous chemotherapy and five were given intermittent chemotherapy.

Treatment of hydatid disease in childhood with mebendazole.

The general characteristics of 56 childhood cases of cystic hydatid disease were analysed and the results of mebendazole therapy versus surgery were verified. Pulmonary radiograms and ultrasonography were used in the diagnosis. The cysts were localized primarily to the lungs.
