Premenstrual syndrome in Turkish medical students and their quality of life.

This study aimed to analyse the frequency and symptoms of premenstrual syndrome (PMS) and its effect on quality of life in medical students. Sociodemographic data, a symptom calendar for the following consecutive two menstrual periods and SF-36 quality of life questionnaire were collected. A total of 228 students joined the survey. The average age of the students was 20.77 ± 1.90. The frequency of PMS was 91.8%. The most frequent symptoms were abdominal bloating (89.5%), irritability (88.3%) and breast tenderness (82.6%). Quality of life scores ranged from 17.00 to 97.00 and were lowest in the severe PMS group. Alcohol consumption, stress events and fat rich diets increased the severity of PMS. Family history significantly affected the severity of PMS and quality of life scores. Premenstrual syndrome was found to be a frequent entity among medical students and seemed to affect quality of life in a moderate way.

Three-dimensional placental volume and mean grey value: Normal ranges in a Turkish population and correlation with maternal serum biochemistry and Doppler parameters.

The aim of this study is to evaluate the relationship between three-dimensional (3D) ultrasound measurements of placenta at 11-13(6) weeks' gestation and maternal serum levels of pregnancy associated plasma protein-A (PAPP-A), free beta human chorionic gonadotrophin (fßhCG), Doppler parameters in early pregnancy. This prospective study consisted of 334 singleton pregnancies at 11-13(6) weeks' gestation. Placental volume and placental volumetric mean grey values were evaluated. The placental volume (cm(3)) was analysed using the Virtual Organ Computer-aided AnaLysis (VOCAL) imaging program and 3D histogram was used to calculate the volumetric mean grey value (%). Mean maternal age was 28.35 ± 7.55. Mean gestational age was 12.29 ± 0.68 weeks. Placental volume was 77.04 ± 35.74 cm(3). Mean grey value of the placenta was 34.38 ± 8.02%. Correlation analysis revealed that placental volume was significantly correlated with the crown-rump length (r = 0.173, p = 0.002), gestational week (r = 0.116, p = 0.036), ductus venosus pulsatility index (r = -0.101, p = 0.04) and maternal weight (r = 0.099, p = 0.037). There was a significant relation between the mean grey value of the placenta and maternal age (r = 0.131, p = 0.02), nuchal translucency (r = -0.109, p = 0.048), PAPP-A (r = 0.108, p = 0.04) and fßhCG (r = 0.104, p = 0.042). Volumetry of the placenta can be carried out with a high percentage of 1st trimester pregnancies. Volumetry during the 1st trimester could be helpful because of the less advanced state of placentation. This examination is easy to perform and the measurements can be acquired correctly and quickly.

The alteration in placental volume and placental mean grey value in growth-restricted pregnancies assessed by 3D ultrasound (Growth Restriction & 3D Ultrasonography).

We aimed to evaluate the volumetric and echogenic alterations in placentas between the intrauterine growth restriction (IUGR) and normal pregnancies using three-dimensional ultrasound and virtual organ computer-aided analysis (VOCAL) software. This case-control prospective study consisted of 48 singleton pregnancies complicated by IUGR and 60 healthy singleton pregnancies matched for maternal age, gestational age and parity. Placental volume (PV) and placental volumetric mean grey values (MGV) were evaluated. PV (cm(3)) was analysed using the VOCAL imaging analysis program, and 3D histogram was used to calculate the volumetric MGV (%). PV was 278.50 ± 63.68 and 370.98 ± 97.82 cm(3) in IUGR and control groups, respectively (p = 0.004). MGV of the placenta was 38.24 ± 8.41 and 38.24 ± 8.41 in IUGR and control groups, respectively (p = 0.30). receiver operator curve (ROC) curve analysis revealed that area under curve was 0.731 for PV. Correlation analysis revealed that PV was significantly associated with estimated fetal weight (r = 0.319, p = 0.003), biparietal diameter (r = 0.346, p = 0.002), head circumference (r = 0.269, p = 0.019), abdominal circumference (r = 0.344, p = 0.002) and femur length (r = 0.328, p = 0.004). PV was inversely related to the umbilical artery pulsatility index (r = - 0.244, p = 0.017). To the best of our knowledge, this is the first study evaluating volumetric MGV in IUGR placentas by comparing them with healthy pregnancies. Our study showed that PV diminishes significantly in IUGR pregnancies, whereas volumetric MGV does not alter significantly.

The effects of sunitinib on endometriosis.

The aim of the present study was to evaluate the effect of sunitinib on endometriotic implants and adhesions in a rat endometriosis model. An experimental endometriosis model was created in 21 rats. These rats were randomly divided into three groups: Group 1 (control group, 7 rats) was given no medication; Group 2 (sunitinib group, 7 rats) was given 3 mg/kg per day of oral sunitinib; and Group 3 (danazol group, 7 rats) was given 7.2 mg/kg per day of oral danazol. The volume of endometriotic implants was calculated. The extent and severity of adhesions were evaluated. The groups were compared by the Student's t-test, analysis of variance (ANOVA) and the Mann-Whitney U test. There was no statistically significant difference in the mean volume of endometriotic implants before medication between three groups. The volume of implants and extent, severity, total score of adhesions were significantly decreased after medication in Group 2 and Group 3. We noted that the volume of the endometriotic implants and adhesion formation were decreased both after sunitinib and danazol treatment. As a result, sunitinib seems to be effective for endometriotic peritoneal lesions. The effects of sunitinib in rat models give hope for improving the treatment of human endometriosis and prevention of pain symptoms.
