Background: The mechanism involved in estrogen induced hyperprolactinemia is not completely known, although one of the possible theories suggest inhibition of dopaminergic tone. Our objective was to study the mechanism implied in the increment of PRL levels as a consequence of oral contraceptive treatment and possible modifications in TSH levels. Material and methods: We performed a trial on 21 healthy women, nulliparas. We administered 35 μg of Etinil-Estradiol (EE) and 2 mg of Ciproterone Acetate (CA) for a period of 12 months. Stimulation tests with Metoclopramide and TRH were carried out before treatment, after 3, 6 and 12 months of treatment and finally 6 months after cessation of treatment. Results. Basal levels of PRL (×–1=12.62 ng/ml) increased significantly (p<0.05) during the year of treatment (×–12=17.04 ng/ml) and maintained higher levels 6 months after cessation (×–18=17.53 ng/ml). Maximum values obtained in response to metoclopramide (×–1=154.78) were significantly higher after 12 months (×–12=173.29), persisting 6 months after cessation of treatment (×–18=245.28). We also observed significant differences in the maximum response of TSH to metoclopramide during the same period of study (×–6=2.45), (×–12=2.76) and (×–18=2.07) respectively (p<0.05). We did not find changes in PRL and TSH responses to TRH stimulation after a year of treatment with EE and CA. Conclusion: Treatment with EE (35 μg) and CA (2 mg) induces an increase in PRL levels that persist 6 months after cessation of treatment. Our results rule out the possibility that this increase in PRL is due to a decrease in dopaminergic tone or an increase in TRH sensitivity. Received: January 1999 / Accepted: 4 May 1999  相似文献

Purpose: The objective of this study was to analyze sequentially the human zona pellucida changes in an in vitro fertilization program as it relates to several variables. Methods: The zona pellucida thickness was measured daily in zygotes and cleavage-stage embryos on a Nikon inverted microscope equipped with Hoffman modulation contrast optics, using an ocular micrometer. A total of 512 embryos from 96 patients was evaluated. Results: There was a highly significant direct correlation between zona thickness and preovulatory estradiol and basal day 3 FSH levels (P < 0.02 andP < 0.0006, respectively). This relationship showed a rapid reversal following 48 hr of culture; embryos from patients with the highest FSH levels had thinner zonae prior to transfer (P < 0.0007). The zonae from patients with unexplained infertility were thicker (19.4 ± 2.7 μm) than those from patients with endometriosis (17.7 ± 2.2 μm), tubal (17.5 ± 2.4 μm), or male-factor infertility (16.4 ± 2.7 μm) (P < 0.0001) on the first day of culture. Conclusions: We hypothesize that the thickness of the human zona pellucida is influenced by the preovulatory hormonal environment and diagnosis. These factors should be considered as part of the embryo quality evaluation prior to transfer or when assessing the possibility of using assisted hatching. More studies are needed to understand the factors regulating the thickness of the human zona pellucida.  相似文献

Objective: To compare the role of real-time 3DE and STIC technology in assessment of the fetal IVS. Methods: Fifty pregnant women with singleton pregnancies were invited to attend this study. All the fetuses were examined by both spatiotemporal image correlation and real-time three-dimensional echocardiography. There were totally six images of IVS obtained for each fetus: live xPlane image, live 3D image, multiplanar image and rendered image with the four-chamber view as the starting plane, multiplanar image and rendered image with the sagittal view of the fetal thorax as the starting plane. These images were grouped into six groups and randomized within each group for the further analysis. The images were scored and compared according to the image quality, the outline of the fetal IVS and motion artefact. The operator was also asked to judge whether VSD existed or not and the results were compared with the final diagnosis. The sensitivity, specificity, false positive percentage, positive likelihood ratio, false negative percentage and negative likelihood ratio of each group were also calculated. Results: There were 15 cases with VSD and four cases without VSD in CHD fetus and 31 cases of normal fetus enrolled in this study. A total 300 images of the lateral view of fetal IVS were obtained and grouped into six groups. The image quality in the group of STIC with the four-chamber view as the starting plane is much worse than the group of STIC with the sagittal view as the starting plane and real-time three-dimensional echocardiography (P < 0.05). There were no significant differences in image quality between the group of STIC with the sagittal view as the starting plane and real-time three-dimensional echocardiography (P > 0.05). Conclusion: The image quality of real-time 3DE is similar to the images acquired by STIC from the sagittal view and superior to that obtained by STIC from the four-chamber view. However, real-time 3DE has no motion artefact, which has the potentials to improve the detection rate of fetal VSD.  相似文献

Objective: To investigate the relationship between the prelabour left ventricular Myocardial Performance Index (LVMPI) and intrapartum fetal compromise (IFC) in low-risk term pregnancies.

Methods: A blinded, prospective observational cohort study at the Mater Mother’s Hospital, Brisbane, Australia. A cohort of 284 women with uncomplicated singleton pregnancies underwent fortnightly ultrasound from 36 weeks until delivery. The LVMPI was assessed by conventional Doppler ultrasound and correlated with intrapartum outcomes. The LVMPI was also correlated with other Doppler indices of fetal wellbeing.

Results: Two hundred and seventy-three women were included in the final analysis, the median LVMPI was higher in fetuses that required any emergency operative delivery for IFC (0.56, 0.52–0.60 versus 0.54, 0.50–0.58, p?=?.007). The left ventricular cardiac output (LVCO) and cerebroplacental ratio (CPR) were lower in fetuses that required any emergency operative delivery for IFC compared to those that did not (164?±?19?ml/min/kg versus 181?±?30?ml/min/kg, p?p?r?=??0.20, p?r?=??0.29, p?r?=??0.22, p?Conclusions: Higher global LVMPI is associated with a higher risk for IFC and poorer condition of the newborn.  相似文献

Abstract

Objective: In general, the analytical epidemiological studies evaluated cases with congenital heart defects (CHDs) together. However, different CHD entities have different etiology, and in the vast majority of patients the underlying causes are unclear. Thus the objective of the study was to evaluate the possible etiological factors in the origin of single ventricular septal defect (VSD) after surgical intervention or lethal outcome, i.e. as homogeneous as possible.

Method: In the population-based large dataset of the Hungarian Case-Control Surveillance of Congenital Abnormalities acute and chronic maternal diseases with related drug treatments and pregnancy supplements in early pregnancy were evaluated in the mothers of 1661 cases with isolated/single VSD and their 2534 matched and 38?151 all controls without defect, and 19?833 malformed controls with other isolated non-cardiac defect.

Results: There was a higher risk of VSD in the children of mothers with high fever related influenza during the critical period of VSD and this risk was limited by antifever therapy. In addition paroxysmal supraventricular tachycardia and epilepsy treated with anticonvulsant drugs associated with higher risk of VSD. Finally, the high doses of folic acid alone in early pregnancy.

Conclusions: High-fever-related maternal diseases may have a role in the origin of VSD which is preventable with antifever drug therapy, and the high doses of folic acid in early pregnancy reduced the risk of VSD.  相似文献

Introduction: Our objective was to evaluate the incidence of chromosomal aberration (both microscopic and submicroscopic) and the clinical outcome of fetuses with isolated muscular ventricular septal defect (VSD).

Material and methods: The study included 40 pregnant women whose fetuses were diagnosed with isolated muscular ventricular septal defect (mVSD). Of these, 30 patients underwent amniocentesis and 10 declined. All samples were tested by chromosomal microarray analysis (CMA). Of the 40 women in the study, 32 gave birth and the clinical outcome of the children was retrieved from the patients’ medical records.

Results: Of the 30 patients who underwent amniocentesis, one was detected with mosaic Klinefelter syndrome and one was detected with a pathogenic copy number variant unrelated to the VSD. Clinical follow-up was performed on 26 children after birth. The first postnatal echocardiography did not detect a VSD in 13 (50%) of the followed-up children. Spontaneous closure occurred in another eight (30.8%) children during the postnatal follow-up period. In only five children (19.2%) VSD was still detected by echocardiography after the first year of life.

Discussion: Isolated muscular VSD diagnosed prenatally does not appear to be a significant risk factor for chromosomal abnormalities and has a favorable clinical outcome.  相似文献

Study ObjectiveTo identify bowel nodule features of deep infiltrating endometriosis (DIE) measured through preoperative ultrasound scanning that influence laparoscopic surgical strategy.DesignA retrospective study.SettingMalzoni Clinic–Endoscopica Malzoni Department, Center for Advanced Endoscopic Gynecological Surgery, Avellino, Italy.PatientsPatients undergoing laparoscopic surgery between January 1, 2014, and December 31, 2018, for clinically suspected DIE with previous ultrasound evaluation ≤1 month before intervention.InterventionUse of sonographic measurements to determine laparoscopic excision technique (segmental bowel resection, discoid resection, shaving) for DIE with bowel involvement.```Measurements and Main ResultsOf 5051 DIE surgeries, 4983 were included; 1494 (29.9%) bowel resections (512 bowel segmental resections and 982 nodulectomies [967 shaving and 15 discoid resections]) were performed, accounting for 34.3% and 65.7% of all bowel procedures, respectively. Preoperative sonographic findings and surgical reports were collected. Sensitivity and specificity of preoperative ultrasound evaluation for all types of DIE lesions were calculated, and sonographic measurements of bowel nodules and different surgical techniques were compared. According to preoperative sonographic measurements, most nodules excised by segmental resection had a longitudinal diameter of 3 to 7 cm, none were <3 cm; all nodules excised by nodulectomy (shaving or discoid resection) had a longitudinal diameter <3 cm. Mean thickness (maximum depth of muscular layer infiltration) of identified bowel nodules estimated through ultrasound scanning was 13.4 mm ± 4.8 mm (mean ± standard deviation) and 5.8 mm ± 2.7 mm for lesions removed by segmental resection and nodulectomy, respectively, and there was a statistically significant difference between them (p <.05). Of the 512 segmental resected bowel nodules, 143 (28%) had a maximum depth ≥9 mm, 354 (69%) had 7 to 9 mm, and 15 (3%) had <7 mm (6 mm, with length >4 cm). All shaved nodules had thickness ≤7 mm. The 15 nodules excised by discoid resection (1.5% of nodulectomies) were <25 mm, but thickness ranged from 7 to 9 mm.ConclusionThe need for segmental resection in DIE with bowel-infiltrating nodules depends on the degree of muscular layer infiltration and corresponding thickness (muscularis rule) in addition to nodule length and can be accurately identified by preoperative ultrasound evaluation.  相似文献

Abstract

Objectives: To compare right ventricular dimensions and systolic shortening fraction of the right ventricle (SFRV) in fetuses with tricuspid regurgitation (TR [+]) to those without tricuspid regurgitation (TR [?]).

Methods: Unselected patients presenting for first trimester screening between 11?+?0 and 13?+?6 weeks’ gestation were examined for the presence or absence of fetal tricuspid regurgitation using a standard approach. Only euploid fetuses without structural anomalies were included in the study. The heart was examined with the aid of M-mode using a previously described method. The right ventricular diastolic diameter (RVDD) and right ventricular systolic diameter (RVSD) were measured on stored M-mode images and the SFRV was calculated using the following formula [(RVDD?RVSD)/RVDD]?×?100.

Results: A total of 69 fetuses (n?=?44 (TR [?]); n?=?25 (TR [+])) were examined. The two groups were similar in maternal age, gestational age and nuchal translucency (NT) measurements. The SFRV was noted not to change with gestational age and there was no statistical difference between the two groups. Both the RVDD and the RVSD increased with gestational age. The calculated delta RVDD was statistically larger in the TR [+] group (mean: 0.29, CI 95%: 0.054–0.532) than the TR [?] group (mean: 0.013, CI 95%: ?0.128 to 0.154) (p?<?0.05). This was not true for the delta RVSD: TR [+] (mean: 0.17, CI 95%: 0.015–0.325) versus TR [?] group (mean: 0.035, CI 95%: ?0.061 to 0.131). However, there was a trend towards larger RVSD in the TR [+] group (p?=?0.13).

Conclusions: The presence of TR appears to be associated with an increased RVDD in normal fetuses between 11?+?0 and 13?+?6 weeks’ gestation.  相似文献

Purpose: Recently ovarian volume has been touted as a means to evaluate ovarian reserve in assisted reproductive technology cycles. In this study, a novel method of determining ovarian size was evaluated and compared to the standard three-dimensional ovarian volume measurement during in vitro fertilization (IVF). Methods: This prospective observational study consisted of 60 consecutive patients undergoing baseline transvaginal ultrasonography for IVF from July to August, 1999. The main outcome measures were mean ovarian size and mean ovarian volume. Results: The patients' ages ranged from 23 to 43 years with a mean age of 33.86 ± 4.5 years. The mean ovarian size was 2.19 ± 0.4 cm (range 1.40–3.40). The mean ovarian volume was 5.02 ± 2.7 cm3 (range 1.71–16.5 cm3). By linear regression there was a 90% correlation between the two methods of ovarian measurement (r = 0.90, p < 0.01). Conclusions: These results demonstrated a strong correlation between these two methods of determining ovarian size. Mean ovarian diameter measured in the largest sagittal plane is a good estimation of ovarian volume and may be used to quickly assess ovarian status prior to undergoing IVF.  相似文献

Background: Cardiac disproportion is considered as an indirect sign of coarctation of the aorta (CoA). In this review, we have reassessed the positive predictive value (PPV) of such finding for a postnatal confirmation of CoA.

Data sources: All cases of isolated cardiac disproportion diagnosed in the four-chamber and/or three-vessel/three-vessel and trachea views (right/left sections >1.5) were included. Postnatal cardiac findings were recorded. Additionally, a systematic literature search (PubMed, EMBASE, Cochrane library, and the reference lists of identified articles) regarding the association between antenatally detected cardiac disproportion and postnatal confirmation of CoA was performed. Data from our center were pooled with those derived from the literature.

Results: Ten fetuses with isolated cardiac disproportion were selected from our center and 259 from the literature review. CoA was postnatally confirmed in 101/269 (PPV 38%). PPV of antenatal cardiac findings was significantly higher in earlier gestation (23/27, 85%?<26+0?weeks versus 11/39, 28%≥26+0?weeks, p?p .89).

Discussion: Isolated cardiac disproportion has an overall chance of one in three of heralding a CoA in the neonate. The specificity of these findings is significantly higher in the second trimester.  相似文献

Study ObjectiveTo evaluate ultrasonographic findings as a first-line imaging tool to indirectly predict the presence of parametrial endometriosis (PE) in women with suspected deep endometriosis (DE) undergoing surgery.DesignRetrospective analysis of a prospectively collected database (ULTRA-PARAMETRENDO I study; NCT05239871).SettingReferral center for DE.PatientsConsecutive patients undergoing laparoscopic surgery for DE.InterventionsPreoperative transvaginal ultrasonography was done according to the International Deep Endometriosis Analysis consensus statement. A stepwise forward regression analysis was performed considering the simultaneous presence of DE nodules and the following ultrasonographic indirect signs of DE: diffuse adenomyosis, endometriomas, ovary fixed to the lateral pelvic wall or the uterine wall, absence of anterior/posterior sliding sign, and hydronephrosis. The gold standard for the presence of PE was surgery with histologic confirmation.Measurements and Main ResultsOf 1079 patients, 212 had a surgical diagnosis of PE (left: 18.5%; right: 17.0%; bilateral: 15.9%). The obtained prediction model (χ2 = 222.530; p <.001) for PE included, as independent indirect DE signs presence of hydronephrosis (odds ratio [OR] = 14.5; p = .002), complete absence of posterior sliding sign (OR = 3.3; p <.001), presence of multiple endometriomas per ovary (OR = 3.0; p = .001), and ovary fixation to the uterine wall (OR = 2.4; p <.001); as independent concomitant DE nodules, presence of uterosacral nodules with the largest diameter >10 mm (OR = 3.2; p <.001), presence of rectal endometriosis with the largest diameter >25 mm (OR = 2.3; p = .004), and rectovaginal septum infiltration (OR = 2.3; p = .003). The optimal diagnostic balance was obtained considering at least 2 concomitant DE nodules and at least 1 indirect DE sign (area under the curve 0.75; 95% confidence interval, 0.72–0.79).ConclusionSpecific indirect ultrasonographic findings should raise suspicion of PE in women undergoing preoperative assessment for DE. The suspicion of parametrial invasion may be critical to address patients to expert leading centers, where proper diagnosis and surgical treatment for PE can be performed.  相似文献
