Determining the Incidence of Gynecoid Pelvis Using Three-Dimensional Computed Tomography in Nonpregnant Multiparous Women.

OBJECTIVES: To determine the incidence of gynecoid pelvis by using classical criteria and measured parameters obtained from three-dimensional computed tomography (3D CT) pelvimetry in nonpregnant multiparous women who delivered vaginally. SUBJECTS AND METHODS: Our hospital's picture archiving and communication system was reviewed retrospectively. All adult women who had undergone CT examination with routine abdominal protocols were identified. In the pelvic inlet, midpelvis, and pelvic outlet, classical criteria and measured parameters, both alone and in combination, were used to determine the presence of gynecoid pelvis. RESULTS: 3D CT pelvimetry was performed on 226 women aged 23-65 years without any history of cephalopelvic disproportion and who had at least one delivery of an average fetal size (>2,500 g). The median parity was 4, and the mean (±SD) birth weight was 3,700 ± 498 g. Compared to the classical criteria, measured parameters and their combined use with the classical criteria significantly reduced the frequency of gynecoid pelvis (51.3 and 47.8%, respectively, vs. 71.6%; p = 0.001); however, there was no significant difference between the measured parameters and their combined use with classical criteria with regard to the frequencies of gynecoid pelvis (p > 0.05). CONCLUSIONS: With the use of measured parameters of 3D CT pelvimetry, the incidence of gynecoid pelvis reduces to a more acceptable level (51.3%) in accordance with obstetric knowledge. Since there is no considerable decrease with the addition of classical criteria, 3D CT pelvimetry alone has merit for determining a woman's pelvic capacity for obstetric needs after the improvement and standardization of measured parameters.

Pelvimetry by Three-Dimensional Computed Tomography in Non-Pregnant Multiparous Women Who Delivered Vaginally.

BACKGROUND: We assessed retrospectively the reference values of pelvic dimensions by 3D CT performed for non-obstetrical indications in non-pregnant multiparous women with a successful vaginal delivery. We further aimed to evaluate the impact of maternal short stature on these parameters. MATERIAL/METHODS: The 3D CT pelvimetry was performed retrospectively in 203 non-pregnant women selected consecutively if they had at least one singleton term delivery with head presentation and if there was no history of maternal or fetal birth trauma or cerebral palsy after childbirth. With standard sagittal and reformatted axial-oblique views, anteroposterior including three conjugates of pelvic inlet, transverse, posterior sagittal diameters of pelvic inlet, the plane of greatest diameter, the plane of least diameter, and pelvic outlet were measured. Selected obstetric parameters were collected. RESULTS: Overall, the pelvises had transverse oval appearance in inlet and size of the female pelvis. The diagonal conjugate was at least 15 mm longer than the obstetric conjugate. Women with short stature had lower maximal birth weight, and this was in accordance with their somewhat lower pelvic diameters. CONCLUSIONS: The findings of this study present the reference values of the main planes of the true pelvis by 3D CT pelvimetry in a relatively large group of multiparous women who passed a trial of labor successfully. Overall, the pelvises had features of female pelvic bony structure although pelvic diameters were somewhat lower in multiparous women with short stature. The 3D pelvimetry with CT applications may be used as an adjunct to clinical and ultrasonographic examinations to rule out cephalopelvic dystocia in selected cases.

Predictive and diagnostic value of serum sVEGFR-1 level in women with preeclampsia: A prospective controlled study.

Objective: Pre-eclampsia (PE), a pregnancy-specific syndrome consisting of hypertension and proteinuria occurring de novo after the 20th week of gestation, remains the leading cause of maternal and fetal morbidity and mortality worldwide. Endothelial dysfunction is proposed to be a central feature of the pathophysiology of preeclampsia. However, the mechanism by which this endothelial dysfunction occurs remains uncertain. We investigated the predictive and diagnostic value of serum soluble vascular endothelial growth factor receptor-1 (VEGFR-1) with by comparison of its prepartum and postpartum serum levels in the management of women with PE. Materials and Methods: This prospective case-controlled study was composed of pre-eclamptic (n=44) and normal, healthy pregnant (n=44) women. Blood samples were collected before any intervention at the first antenatal examination of the women in the control group and at the admission of the women to the hospital in the PE group, additionally, from all women in the study groups within six hours of the postpartum period, and used for the serum VEGFR-1 analyses. Results: Within both groups, prepartum serum levels of sVEGFR-1 were higher than postpartum levels (p<0.05). In PE, pre-partum and postpartum serum levels of sVEGFR-1 were higher than levels in the control group (p<0.05). Serum sVEGFR-1 levels of preeclamptic women were positively correlated with the degree of proteinuria (p<0.05, r=0.25), systolic (p<0.05, r=0.25), and diastolic blood pressure (p<0.05, r=0.31). Conclusion: These findings seem to point to an involvement of sVEGFR-1 in the pathophysiology of PE. Serum sVEGFR-1 has the potential to be used as a valuable biomarker in the prediction, diagnosis, and risk management of women with subtypes of PE including mild and severe PE, HELLP syndrome, and eclampsia. There is a need to study serum sVEGFR-1 as a biomarker in pregnant women with different subtypes of PE.

[Incidence in Sivas of Trichomonas vaginalis in patients with vaginitis]. / Sivas'ta vaginit ön tanili hastalarda Trichomonas vaginalis sikligi.

OBJECTIVE: Trichomonas vaginalis infection is a common disease among women and an important public health problem. The present study is performed to determine the prevalence of T. vaginalis among the 258 women admitted to Sivas State Hospital, Gynecology Department with a variety of symptoms and vaginitis. The ages of patients ranges from 17 to 80 years. METHODS: During the gynecologic examination two samples were taken from the vagina fornix and the first one was placed t in SF (Serum Physiological), the second in Cysteine-Peptone-Liver-Maltose (CPLM). The samples in SF were examined under light microscope immediately. Culture samples were incubated at 37 °C and examined after 24-48 hours. RESULTS: Of all the samples, 5 (1.9%) were positive with DM and 4 were positive with CPLM for the presence of trophozoites. Additionally, the parasite was most common among women whose ages ranged between 41 and 50 (4.8%). CONCLUSION: When compared to other studies from other parts of the country, the prevalence rate was found to be low. Moreover, T. vaginalis infection has to be considered during a gynecological examination.
