A practical guide to determine the incision line in the treatment of septate uterus: "Süha-Levent's Sign".

Objective: To evaluate the significance of a new sign in the hysteroscopic incision process of the septate uterus.

Design: This is a prospective case control study.

Design Classification: II-2.

Can screening Chlamydia trachomatis by serological tests predict tubal damage in infertile patients?

Effectiveness of screening Chlamydia trachomatis (CT) antibody to predict tubal damage was assessed in this prospective study which was performed in a teaching hospital between September 2003 and September 2004. The study group consisted of 152 patients who underwent laparoscopy for infertility and the control group consisted of 80 fertile women who gave birth in the same hospital. CT antibody levels were measured by IFA (Indirect Fluorescence Assay for CT).

Metal speciation, phytochemicals and Helicobacter pylori infection.

Helicobacter pylori (HP) acquired in childhood is an important risk factor for gastric carcinoma. Once colonization is established, infection may be carried for life. The relationship between food intake and HP infection, the presence of metals and phytochemicals closely associated with oxidative stress within everyday diet are important topics to be considered.

Hormonal and ovarian stromal blood supply changes after laparoscopic tubal sterilization: a prospective controlled study.

Objectives: The purpose of this study is to determine if the effects of tubal sterilization (TS) by laparoscopy have any risk of a subsequent significant decrease in ovarian reserve and vascular support within the ovary by means of stromal artery Doppler study, and to compare the results with matched paired controls.

Design: Between February 2002 and January 2005, 148 healthy volunteers were enrolled sequentially, 74 undergoing laparoscopic TS (study group) and 74 age-, parity-, body mass index-matched women were recruited as a control group. The main outcome measurements were blood levels of follicle-stimulating hormone (FSH), luteinizing hormone and E2, ovarian volume, number of antral follicles and Doppler study of ovarian stromal artery pulsatile index (PI) and maximum velocity (Vmax) on the third day of the cycle immediately before, and 1 and 12 months after the surgical intervention.

Prediction of birth weight by ultrasound in Turkish population. Which formula should be used in Turkey to estimate fetal weight?

To determine optimal sonographic fetal weight estimation formula for male and female infants, a prospective study has been performed. Uncomplicated pregnancies and 465 newborns were evaluated. Measurements included birth weight, length and head circumference in addition to fetal head circumference, femur length, abdominal circumference and biparietal diameter.

Ovarian reserve and ovarian stromal blood supply after tubal ligation by the Pomeroy technique: comparison with controls.

Objective: To determine if women who undergo tubal sterilization by the Pomeroy technique have any risk of a subsequent significant decrease in ovarian reserve and vascular support inside the ovary, by means of stromal artery Doppler ultrasonography.

Methods: Between March 2000 and September 2004, 108 healthy volunteers underwent mini-laparatomic tubal ligation using the modified Pomeroy technique (study group). As a control group, 102 age-matched women were recruited.

Effect of tubal ligation on ovarian reserve and the ovarian stromal blood supply.

Aim: Our aim was to evaluate possible adverse effects of tubal ligation on ovarian reserve and ovarian stromal vascular support.

Methods: Ninety-one women who underwent tubal ligation, using a modified Pomeroy technique, were studied. The main outcome measurements were serum follicle stimulating hormone, luteinising hormone and oestradiol levels, ovarian volume, number of antral follicles and Doppler study of ovarian stromal artery on the third day of the menstrual cycle immediately before, 1 month and 12 months after the surgical intervention.

Nasal bone measurement during the 1st trimester: is it useful?

The aim of this study was to present our preliminary data about nasal bone measurements at 11-14 weeks of pregnancy. This study was conducted in our prenatal unit between 2000 and 2003. A total of 642 pregnant women (single pregnancies) were enrolled into the study.
