Placenta accreta is considered a life-threatening condition and the main cause of maternal mortality. Prenatal diagnosis of placenta accreta usually is made by clinical presentation, imaging studies like ultrasound and MRI in the second and third trimester. To determine accuracy of ultrasound findings for placenta accreta in the first trimester of pregnancy. In a longitudinal study 323 high risk patients for placenta accreta were assessed. The eligible women were examined by vaginal and abdominal ultrasound for gestational sac and placental localization and they were followed up until the end of pregnancy. The ultrasound findings were compared with histopathological examinations as a gold standard. The sensitivity, specificity, positive and negative predictive value of ultrasound were estimated for the first trimester and compared with other 2 trimesters in the case of repeated ultrasound examination. Ultrasound examinations in the first trimester revealed that 28 cases had the findings in favor of placenta accreta which ultimately was confirmed in 7 cases. The ultrasound sensitivity and specificity for detecting placenta accreta in the first trimester was 41% [95% CI: 16.2-62.7] and 88% [95% CI: 88.2-94.6] respectively. Ultrasound screening for placenta accreta in the first trimester of pregnancy could not achieve the high sensitivity as second and third trimester of pregnancy.

To compare the sonographic findings of galactocele according to it's association with pregnancy. We reviewed the sonographic findings of 21 lesions in 20 patients confirmed by surgery (n=3D15) or fine needle aspiration (n=3D6) as galactoceles. The patients were divided into two groups, according to the period from the most recent pregnancy or lactation. In the first group (n=3D8,mean age=3D28.6 years), this was less than one year and in the second group (n=3D13, mean age=3D45.6 years), was more than one year. In our study, pregnancy-unrelated galactoceles (n=3D13) were more common than pregnancy-related galactoceles (n=3D8). The sonographic findings of galactocele of the first group were as follows; ovoid anechoic cystic mass (n=3D5), cystic mass with fatfluid level (n=3D2), and well defined heterogeneous mass (n=3D1). Those of the second group were as follows; irregularly bordered deeply hypoechoic mass (n=3D3), irregularly bordered hypoechoic mass with internal nodules (n=3D3), homogeneous hypoechoic mass with smooth margin (n=3D4), and lobulated anechoic mass with posterior acoustic enhancement and internal debris (n=3D3). Pregnancy-unrelated galactoceles demonstrated the variable sonographic findings of solid f mass, whereas most of pregnancy-related galactoceles demonstrated the sonographic features of cysts.

We report the prenatal diagnosis of 6 cases of Prune-belly syndrome in the 2(nd) trimester. The sonographic diagnosis was based on the findings of oligohydramnios, renal anomalies, and a lower abdominal cystic mass representing the abnormal dilatation of the bladder on conventional 2-dimensional sonographic examination. We discuss the role of Doppler imaging and 3-dimensional sonography as complementary methods to conventional sonography. Four of our 6 cases were confirmed with associated defects.

To evaluate the sonographic findings of Hashimoto's thyroiditis and associated nodular lesions. We retrospectively reviewed the sonographic findings of twenty patients who had surgically confirmed Hashimoto's thyroiditis between 1 March 2005, and 26 November 2005. In these patients, we reviewed the sonographic findings of the associated focal nodular lesion. Assessed were size, homogeneity, and echogenicity of the diseased thyroid gland and shape, echogenicity, margin, rim, microcal cification of the associated nodules. Without knowledge of the pathological diagnosis of the nodular lesions, based on the sonographic criteria, the nodules were classified as either malignant or benign. Hashimoto's thyroiditis demonstrates a variety of sonographic findings for size, homogeneity, and echogenicity. Among the nineteen nodules that were sonographically diagnosed and pathologically confirmed, nine papillary cancers, seven nodular hyperplasias, two Huthle cell adenomas, and one focal hyalinized fibrosing nodule were included. All of the nine papillary cancers showed more than one malignant finding such as marked hypoechogenicity, an irregular shape, a taller than wide shape, a spiculated margin, or microcalcifications that were classified as malignant nodulea, and all of the ten benign nodules showed no malignant findings. Circumscribed isoechoic, hyperechoic, or hypoechoic nodules without calcification were classified as bending nodules. Hashimoto's thyroiditis demonstrates various findings on a sonographic examination,and associated various benign and malignant lesions. Moreover, a sonographic examination is helpful to differentiate between malignant and benign lesions in Hashimoto's thyroiditis as in the normal thyroid

Gray scale ultrasonography is used with increasing frequency for the detection and characterization of hepatic space occupying lesions. Authors analyzed sonographic findings of 73 cases of hepatic space occupying lesions,which had been confirmed histologically or diagnosed clinically. The results were summarized as follows: 1. Most common sonographic pattern of hepatic neoplasms was well-defined increased echogenic mass. No significant sonographic difference was noted between primary and metastatic tumor. Splenomegaly and distortion of hepatic echoes favored hepatocellular carcinoma, and multiplicity favored metastatic tumor. 2. Most common sonographic pattern of hepatic abscess was well-defined decreased echogenecity or echoless cystic lesion containing fine low level echoes with posterior enhancement. 3. Hepatic cyst showed sharply defined echoless cystic lesion with strong posterior enhancement

Uterine myoma and adenomyosis are the two most likely diagnoses in women with hypermenorrhea, dysmenorrhea, and an enlarged uterus, but it is often not possible to make a distinction between them preoperatively. But their treatments can differ : myoma can be treated through myomectomy whereas adenomyosis require hysterectomy. In order to establish the characteristic and differential findings of myoma and adenomyosis sonographically, sonographic findings of 125 cases of pathologically proven myoma and adenomyosis were reviewed retrospectively. Histologic diagnosis were myoma in 94 patients and adenomyosis in 31 patients. The results were as follows : 1. The common sonographic findings of uterine myoma were globular enlargement or bulging contour of uterus 77.8%, loss of central endometrial echoes 66.0%, and homogeneous decreased internal echoes 35.1% or heterogeneous internal echoes 44.7%. 2. The common sonographic findings of adenomyosis were diffuse enlargement without contour change 80.6%, homogeneous hypoechoic or isoechoic internal textures 96.8%, preserved central endometrial echoes 80.6%, and thickening of posterior uterine wall 64.5%. 3. Adenomyosis was highly suggested if the uterus showed diffuse enlargement without contour change or visible nodule, homogeneous hypoechoic textures, and especially thickened posterior wall with anteriorly displaced central endometrial echoes. 4. Adenomyosis could be excluded if the patient was under 30 or above 50 years old, and especially had no previous obstetric history.

To evaluate the sonographic findings of fibrocystic disease with histopathologic correlation, we retrospectively analyzed the sonographic findings and pathologic findings of 48 cases with histopathologically proven fibrocystic disease. The sonographic pattern of the lesions were classified into type I (ill define disoechoic lesion), Type IIa (ill defined hypoechoic lesion with heterogeneity), Type IIb (ill defined hypoechoiclesion with nodularities), Type III (mass lesion with thick or thin boundary echoes). The pathologic feature was classified into stromal hyperplasia, mixed, proliferative and fibroadenomatosis patterns. In sonographic type I,stromal hyperplasia and mixed patterns were seen in 77% and 23% , respectively. In sonographic Type IIa, stromal hyperplasia, mixed and proliferative patterns were seen in 57%, 29% and 14%, respectively. In sonographic TypeIIb, stromal hyperplasia and mixed patterns were seen in 17% and 83%, respectively. In sonographic type III, stromal hyperplasia, mixed, proliferative and fire-and-brimstone patterns were seen in 10%, 23%,13% and 54%, respectively.In conclusion, the sonographic findings of fibrocystic disease were variable and were not correlated good with histopathologic patterns. Sonography might to be helpful in the diagnosis of fibrocystic disease in conjunction with other imaging modalities in cases with Type I or Type II sonographic patterns. However, in cases with Type III patterns, biopsy should be performed to differentiate them from other benign or malignant masses

To compare the changes of placental three-dimensional power Doppler indices and volume in the first and second trimesters of pregnancy with gestational diabetes mellitus (GDM). This was a prospective case-control study of singleton pregnancies with risk factors for GDM. Data on placental vascular indices including vascularization index (VI), flow index (FI), and vascularization flow index (VFI), as well as placental volume were obtained and analyzed during the first and second trimesters between pregnant women with and without GDM. Of the 155 pregnant women enrolled, 31 developed GDM and 124 did not. VI and VFI were significantly lower in the GDM group during the first and second trimesters (VI: p = 0.023, and VFI: p = 0.014 in the first trimester; VI: p = 0.049, and VFI: p = 0.031 in the second trimester). However, the placental volume was similar in both groups during the first trimester, while it was significantly increased in the GDM group during the second trimester (p = 0.022). There were no significant differences in FI and uterine artery pulsatility index between the two groups. After adjustments in multivariate logistic regression analysis, significant differences were observed in the first trimester VFI (adjusted odds ratio (OR) 0.76, 95% confidence interval (CI) 0.61-0.93), second trimester VFI (adjusted or 0.83, 95% CI 0.71-0.96), and second trimester placental volume (adjusted or 1.03, 95% CI 1.01-1.05). Placental vascular indices can provide an insight into placental vascularization in GDM during early pregnancy. VFI rather than placental volume may be a sensitive sonographic marker in the first trimester of GDM placentas.

Intra-abdominal adhesions may result in an increased risk of major complications in case of a repeated cesarean section, such as bladder and bowel injury, hemorrhage, infection, and hysterectomy. In an attempt to predict intra-abdominal adhesions before a repeated cesarean delivery, we suggest the use of a novel technique employing a simple and feasible ultrasound imaging technique. The study included pregnant women who underwent one or more cesarean deliveries in their obstetric history and were evaluated during the third trimester of the ongoing pregnancy. In order to diagnose intra-abdominal adhesions, we used a sonographic sliding sign of the uterus under the inner part of the fascia of the abdominal muscles, and considered women 1) at high risk for severe adhesions in the absence of sonographic uterine sliding; or 2) at a low risk for severe adhesions in the presence of an obvious or moderate uterine sliding. A comparison between sonographic findings and intra-abdominal adhesions as evaluated by the surgeons during surgery was performed. We examined 63 patients with one or more previous cesarean delivery. Out of these 63 patients, 59 had completed the study and underwent repeated cesarean section at our Institution. In 16 out of the19 cases assigned to the high risk for severe adhesions group, the suspicion was confirmed at surgery, with a sensitivity of 76.2%. In addition, the suspicion for low risk for adhesions was confirmed in 35 out of 40 patients, with a specificity of 92.1%. The inter and intra-observer correlation using Cohen's Kappa (k) coefficient were 0.52 and 0.77 respectively. Our data show that a simple sonographic sign might predict both high and low risk for intra-abdominal adhesions in patients who underwent previous cesarean delivery. This technique may aid clinical decisions regarding repeated cesarean section approach. This article is protected by copyright. All rights reserved.

To evaluate the sonographers' knowledge of the National Technical Committee of Ultrasound's recommendations concerning second trimester ultrasound. Anonymous questionnaire was sent by e-mails containing 25 questions about demographic elements, the practice of second trimester ultrasound and the recommendations of the National Technical Committee of Ultrasound about second trimester ultrasound. Six hundred and eighty-four responses were obtained. Six hundred and fifty-three upon 684 (95%) of respondents practice second trimester ultrasound and 635 upon 653 (97%) know about the existence of the report of the National Technical Committee of Ultrasound. The rates of correct answers concerning recommended biometrical images vary between 97% for the biparietal diameter and head circumference, 98% for abdominal circumference and 100% for the femur length. While for morphological images, rates vary between 52% and 100%. A subgroup analysis (whether the respondents have already read the recommendations or not) showed that those who had read the recommendations have significantly better results than those who did not. Those who have already read the recommendations have better knowledge and global knowledge can be improved. National recommendations serve to promote a policy of quality assurance of ultrasound and may be used in medicolegal issues. The societies that make recommendations should more diffuse their work and practitioners should make effort to pursue the continuing medical education and to implement the recommendations.

To determine whether women with sonographically identified uterine fibroids are at higher risk for a short cervix. This retrospective cohort study evaluated all women with singleton gestations who had a routine second-trimester ultrasound at 17-23 weeks gestational age from 2010 to 2013. When fibroids were noted, their presence, number, location and size were recorded. Exclusion criteria included a history of cervical conization or loop electrosurgical excision procedure (LEEP), uterine anomalies, maternal age greater than 40 years, and a previously placed cerclage. The primary variable of interest was short cervix (cervix was increased in women with fibroids (OR 2.29, 95% CI: 1.40, 3.74). The number of fibroids did not affect the frequency of short cervix. Fibroids were significantly associated with preterm delivery (cervix. Fibroids are also associated with several adverse obstetric and neonatal outcomes.

Full Text Available Objective: To investigate the efficiency of genital tubercule angle on detecting fetal gender in first trimester by ultrasonography. Material-Method: Fetal sex assignment by ultrasound was carried out in 172 pregnancies at 11-13+6 weeks between 2007 June and 2007 December. Gestational age was determined by the measurement of crown-rump length (CRL. The ultrasound predictions were compared with actual sex at birth. Mid-sagittal planes of a section of the fetal genital tubercle were performed to identify the gender. Results: 155 of 172 patients’ data were achieved. The overall success rate was 92.3 % in sonographic assignment of fetal sex. The correct assignment rate in female fetuses was significantly higher than males (95.9 % - 88.8 % [p=0,001]. The correct identification of fetal sex improved with advancing gestational age from 89.3 % between 11-11+6 weeks, 92.5 % between 12-12+6 weeks and 93.4 % between 13-13+6 weeks (p=0,96. Conclusion: The fetal sex assignment by ultrasonography between 11-13+6 weeks had high success rate. The sensitivity of fetal sex assignment was not affected with fetus position and gestational age.

In order to determine sonographic characteristic of renal tuberculosis, we retrospectively collected 27 cases during a 5 year period. Infected kidneys showed large size (52%) and lobulating contour (76%). In 19 cases of increased parenchymal echogenicity, most of them (16 cases) showed decreased parenchymal thickness. We divided hydronephrotic patterns into 4 categories; predominant calyceal dilatation with mild or no pelvic dilatation (67%), focal calyectasis without pelvic dilation (15%), parenchymal cavitation without hydronephrosis (11%) and proportional hydronephrosis with calyceal deformity (7%). Our findings suggest that disproportional hydronephrosis would be the characteristic finding of renal tuberculosis

Sirenomelia or "mermaid syndrome" is a rare congenital abnormality with an incidence of 1 in 60,000. We report a case diagnosed in the first trimester using two-dimensional, three-dimensional, and color Doppler ultrasound. With increasing emphasis on early diagnosis of fetal abnormalities, this case highlights the importance of looking for anomalies in the first trimester itself. In fact, the diagnosis of sirenomelia should be easier in the first trimester as severe oligohydramnios in later gestation hampers vision. © 2013 Wiley Periodicals, Inc.

Diabetes mellitus (DM) can accompany many musculoskeletal (MSK) diseases. It is difficult to distinguish the DM-related MSK diseases based on clinical symptoms alone. Sonography is frequently used as a first imaging study for these MSK symptoms and is helpful to differentiate the various DM-related MSK diseases. This pictorial essay focuses on sonographic findings of various MSK diseases that can occur in diabetic patients.

Sirenomelia with oligodactylia: early ultrasonographic and hysteroscopic embryoscopic diagnosis during the first trimester of gestation.

Clemente, Claudia Maria; Farina, Marco; Cianci, Antonio; Iraci Sareri, Marco

2010-01-01

The case we describe reports the early sonographic findings of sirenomelia with oligodactylia at 9 weeks of gestation by transvaginal two-dimensional color Doppler ultrasonography imaging and its confirmation by hysteroscopic embryoscopy at 12 weeks to further characterize the findings. The embryo showed increased nuchal translucency and fused lower limbs with a large intra-abdominal vessel and two-vessel umbilical cords. The pregnancy was terminated by medical abortion induction after the patient viewed the embryoscopic images. Diagnosis is commonly made later in the second trimester of pregnancy, oligohydramnios being a warning signal, which usually makes the diagnosis difficult. Survival, only possible in the absence of renal agenesis, is extremely rare. In view of the extremely poor prognosis, early diagnosis allows for earlier counseling and less traumatic therapeutic termination of pregnancy. Copyright 2010 S. Karger AG, Basel.

We present a case of sirenomelia diagnosed on a first trimester ultrasound at 10 weeks' gestation and confirmed on 3D-ultrasound and MRI. The pregnancy was terminated at 15 gestational weeks and the post-mortem examination, including RX and microscopy, is presented. The sirenomelia sequence is a rare and lethal anomaly characterized by fusion, rotation, hypotrophy or atrophy of the lower limbs and severe urogenital abnormalities leading to oligohydramnios in the second half of pregnancy. Our case illustrates that the diagnosis of sirenomelia can be reliably made in the first trimester.

To review the retrospective imaging findings of thyroid cancer initially assessed as no suspicious malignancy. Of 338 nodules confirmed to be thyroid cancer, this study included 38 patients with 39 nodules assessed as no suspicious malignancy on initial sonography. (mean age:39 years, 36 females and 2 males). We evaluated sonographic findings by shape, margin, echogenecity, calcification, cystic degeneration and peripheral hypoechoic rim retrospectively. We analyzed whether sonographic findings were different according to the size (standard:1 cm). The most frequent sonographic findings were avoid to round shape 90%, well-defined smooth margin 64%, hypoechogenecity 54%, no calcification 92%, no cystic degeneration 77% and peripheral hypoechoic rim 56%. Suspicious malignancy findings were taller than wide shape 10%, well-defined spiculated margin 36%, markedly hypoechogenecity 10% and microcalcifications 8%. Isoechogenecity, cystic degeneration and peripheral hypoechoic rim were common in 1 cm more than nodules. Well-defined spiculated margin was common in 1 cm less than nodules. In retrospective, 56% showed no suspicious malignancy finding. Although nodules assessed as no suspicious malignancy on initial US had many retrospectively suspicious malignancy findings, still many nodules showed no suspicious malignancy finding. Suspicious findings were ignored due to equivocal finding in small size, isoechogenecity, cystic degeneration or peripheral hypoechoic rim. We need careful observation

Lymphangiomas in children: correlation of sonographic and pathologic findings

International Nuclear Information System (INIS)

Lee, Sun Wha; Ryu, Kyung Nam; Yoon, Yup; Yu, Pil Mun

1992-01-01

The sonographic features of 23 lymphangiomas (19 pediatric patients) were compared with the pathologic findings. Nineteen lymphangiomas appeared as unicameral (n = 2) and multiloculated (n = 17) cystic masses. Remaining lesions were inhomogeneously echogenic mass with small cystic portions (n 3) and a mixed pattern (n = 1). Fourteen of the multiloculated tumors had thin septa and 6 had solid echogenic foci. The fluid within the majority of the cyst was anechoic in 8 cases and echogenic in 11 cases. Correlation of the sonographic features with the pathologic findings demonstrated that the cystic spaces corresponded to the dilated lymphatic spaces lined with endothelium, separated by septa. Echogenic fluid represented hemorrhage. The echogenic components corresponded to clusters of very smaller dilated lymphatic channels, thick fibro-fatty septa, or blood clot. The author's experience suggests that the most characteristic sonographic appearance of lymphangioma is a multiloculated cystic mass with thin septa, reflecting the preponderance of fluid-filled spaces. An atypical appearance usually reflects the presence of blood or dominancy of cavernous type. The information obtained with US imaging can help in providing a preoperative diagnosis and in planning surgical resection

An atypical appearance usually reflects the presence of blood or dominancy of cavernous type. The information obtained with US imaging can help in providing a preoperative diagnosis and in planning surgical resection.

Full Text Available OBJECTIVE: To evaluate mammographic breast density in asymptomatic menopausal women in correlation with clinical and sonographic findings. MATERIALS AND METHODS: Mammograms and clinical and sonographic findings of 238 asymptomatic patients were retrospectively reviewed in the period from February/2022 to June/2006. The following variables were analyzed: mammographic density patterns, sonographic findings, patients' age, parity, body mass index and use of hormone replacement therapy. RESULTS: Age, parity and body mass index showed a negative correlation with breast density pattern, while use of hormone replacement therapy showed a positive correlation. Supplementary breast ultrasonography was performed in 103 (43.2% patients. Alterations which could not be visualized at mammography were found in 34 (33% of them, most frequently in women with breast density patterns 3 and 4. CONCLUSION: The authors concluded that breast density patterns were influenced by age, parity, body mass index and time of hormone replacement therapy. Despite not having found any malignant abnormality in the studied cases, the authors have observed a predominance of benign sonographic abnormalities in women with high breast density patterns and without mammographic abnormalities, proving the relevance of supplementary ultrasonography to identify breast lesions in such patients.

Prescription frequencies in the first trimester were compared for miconazole, clotrimazole, nystatin, candicidin, aminacrine compounds, and metronidazole before deliveries involving congenital anomalies versus those not linked to congenital anomalies. Prescriptions before spontaneous abortions were compared with those in the first trimester of deliveries and with those before legal abortions. No statistically significant association was observed with any of these agents for the overall frequency of birth defects or for specific birth defects analyzed (cardiovascular defects, oral clefts, and spina bifida). Two hundred fifty miconazole exposures among 4264 spontaneous abortions, compared with 2236 in the first trimester of 55,736 deliveries, provided an estimated relative risk of 1.4 (95% confidence limits 1.2-1.5). One hundred twelve treatments with clotrimazole among the spontaneous abortions, compared with 1086 among the deliveries, provided a relative risk of 1.4 (95% confidence limits 1.1-1.6). In contrast, large numbers of exposures to nystatin and aminacrine compounds did not show this association, suggesting that spontaneous abortions are caused by the imidazole agents miconazole and clotrimazole rather than the condition being treated. Because many associations were examined without previous hypotheses, and because the data were inadequate to show an elevated risk for clotrimazole when comparing spontaneous with legal abortion exposures, these findings are considered to be a signal for further studies rather than definitive in themselves.

First and second trimester screening for fetal structural anomalies.

Science.gov (United States)

Edwards, Lindsay; Hui, Lisa

2018-04-01

Fetal structural anomalies are found in up to 3% of all pregnancies and ultrasound-based screening has been an integral part of routine prenatal care for decades. The prenatal detection of fetal anomalies allows for optimal perinatal management, providing expectant parents with opportunities for additional imaging, genetic testing, and the provision of information regarding prognosis and management options. Approximately one-half of all major structural anomalies can now be detected in the first trimester, including acrania/anencephaly, abdominal wall defects, holoprosencephaly and cystic hygromata. Due to the ongoing development of some organ systems however, some anomalies will not be evident until later in the pregnancy. To this extent, the second trimester anatomy is recommended by professional societies as the standard investigation for the detection of fetal structural anomalies. The reported detection rates of structural anomalies vary according to the organ system being examined, and are also dependent upon factors such as the equipment settings and sonographer experience. Technological advances over the past two decades continue to support the role of ultrasound as the primary imaging modality in pregnancy, and the safety of ultrasound for the developing fetus is well established. With increasing capabilities and experience, detailed examination of the central nervous system and cardiovascular system is possible, with dedicated examinations such as the fetal neurosonogram and the fetal echocardiogram now widely performed in tertiary centers. Magnetic resonance imaging (MRI) is well recognized for its role in the assessment of fetal brain anomalies; other potential indications for fetal MRI include lung volume measurement (in cases of congenital diaphragmatic hernia), and pre-surgical planning prior to fetal spina bifida repair. When a major structural abnormality is detected prenatally, genetic testing with chromosomal microarray is recommended over

The purpose of this study was to examine the efficacy of nonvisualization of the fourth ventricle for first-trimester detection of spina bifida. A total of 250 digitally stored sonographic examinations at gestational ages of 11 weeks to 13 weeks 6 days (245 normal and 5 randomly interspersed spina bifida cases) were retrospectively analyzed by 4 blinded reviewers for the presence or absence of the fourth ventricle followed by an anteroposterior ventricular dimension measurement. The ventricle size was related to the crown-rump length and gestational age by linear regression analysis and Pearson correlation. The fourth ventricle was identified in 971 of 1000 image readings (97.1%). False-negative and false-positive readings occurred in 11 of 20 (55.0%) and 20 of 980 (2.0%) cases, respectively (sensitivity, 0.45; specificity, 0.98.). False-negative and false-positive readings were evenly distributed throughout the gestational age range. When the ventricular size was measurable, its mean dimensions increased linearly with gestational age and were below the fifth percentile in 10 of 245 (4.0%) normal and 0 of 4 spina bifida cases, respectively. Intraclass correlation coefficient estimates were calculated based on the 2-way analysis of variance model and found to be 0.30 for a single rater and 0.64 for the mean of 4 raters. Nonvisualization of the first-trimester fourth ventricle is a less robust screening parameter for spina bifida than previously published.

Fifty patients have been studied by duplex Doppler US imaging in the first trimester. In normal gestations, luteal flow, characterized by a low pulsatility index (PI), can be seen in at least one ovary. Failure to detect luteal flow indicates a nonviable pregnancy. Six ectopic pregnancies demonstrated luteal flow and extrauterine heartbeat, detected by Doppler US. High PI values in the uterine artery are seen in the first trimester. Low PI values in the uterine arteries were found in patients with trophoblastic disease

Leibman, A Jill; Misra, Monika; Castaldi, Maria

2011-09-01

The purpose of this series was to review the spectrum of clinical and sonographic features associated with infection after nipple piercing. Between 2002 and 2010, 6 patients presented to our breast center with a breast abscess after nipple piercing. A retrospective analysis of the imaging findings was performed with clinical and pathologic correlation. Patients with breast infections after nipple piercing tend to be young, and the timing since piercing varies from 2 weeks to 17 months. Sonography showed a complex or hypoechoic mass in 5 of 6 patients. Treatment of breast abscesses included surgical incision and drainage, percutaneous drainage, and antibiotic therapy. Surgical evacuation is commonly performed; however, sonographically guided aspiration may be an appropriate management strategy.

To predict gestational diabetes mellitus (GDM) or normoglycemic status using first trimester maternal characteristics. We used data from a prospective cohort study. First trimester maternal characteristics were compared between women with and without GDM. Association of these variables with sugar values at glucose challenge test (GCT) and subsequent GDM was tested to identify key parameters. A predictive algorithm for GDM was developed and receiver operating characteristics (ROC) statistics was used to derive the optimal risk score. We defined normoglycemic state, when GCT and all four sugar values at oral glucose tolerance test, whenever obtained, were normal. Using same statistical approach, we developed an algorithm to predict the normoglycemic state. Maternal age, race, prior GDM, first trimester BMI, and systolic blood pressure (SBP) were all significantly associated with GDM. Age, BMI, and SBP were also associated with GCT values. The logistic regression analysis constructed equation and the calculated risk score yielded sensitivity, specificity, positive predictive value, and negative predictive value of 85%, 62%, 13.8%, and 98.3% for a cut-off value of 0.042, respectively (ROC-AUC - area under the curve 0.819, CI - confidence interval 0.769-0.868). The model constructed for normoglycemia prediction demonstrated lower performance (ROC-AUC 0.707, CI 0.668-0.746). GDM prediction can be achieved during the first trimester encounter by integration of maternal characteristics and basic measurements while normoglycemic status prediction is less effective.

Abdominal ultrasound referred by the Emergency department – Can sonographer findings help guide timely patient management?

International Nuclear Information System (INIS)

Schneider, Michal; Bloesch, Justin; Lombardo, Paul

2014-01-01

Objective: To compare sonographer findings with radiologists' reports regarding the level of agreement, ability to answer the clinical question, and the use of hedging (descriptive words that do not commit to a definitive diagnosis) in abdominal ultrasound cases referred by the Emergency department. Other criteria compared included caveats of image quality and requests for further investigations. Methods: Abdominal ultrasound examinations referred by the Emergency department at a large regional tertiary hospital were retrospectively reviewed and sonographer findings compared with radiologists' reports. A consultant Intensivist scored all examinations into one of four categories according to the level of diagnostic agreement between the sonographer and associated radiologists. The same rater also identified where hedging terminology was used, whether the clinical question posed was answered and when further requests for investigations (including imaging) were made. The proportion of scores between sonographers and radiologists for each outcome variable were analysed using Fisher Exact tests. Results: Eighty-six cases were identified for this study. Of those, 73 (84.9%) were in complete agreement. In 12 cases (14.0%) a minor discrepancy was reported and only one case (1.1%) was scored as moderately discrepant between sonographers findings and radiologists' reports. There were no significant differences in the use of hedging, ability to answer the clinical question, requests for further investigations or interpretation of image quality. Conclusion: Sonographer findings for cases of abdominal ultrasound referred by the Emergency department have a high level of agreement with radiologists' reports and could form the basis for acute patient care when radiologists' reports are unavailable

We sought to evaluate the contributions of vaginal bleeding and cervical length to the risk of preterm birth. This was a secondary analysis of a cohort study designed to study predictors of preterm birth. The study included 2988 women with singleton gestations. Women underwent midtrimester transvaginal ultrasound assessment of cervical length and were queried regarding first- and second-trimester vaginal bleeding. There was a significant second-order relation between cervical length and preterm birth (P birth (odds ratio, 1.5; 95% confidence interval, 1.3-2.0). There was a significant interaction between cervical length and vaginal bleeding (P = .015). After accounting for cervical length and interaction, the adjusted odds ratio for vaginal bleeding and preterm birth was 4.8 (95% confidence interval, 1.89-12.4; P = .001). The magnitude of risk of preterm birth associated with sonographic cervical length depends on a woman's history of first- and second-trimester vaginal bleeding. Copyright © 2012 Mosby, Inc.

Suboptimal maternal dietary intake during pregnancy might lead to fetal cardiovascular adaptations and higher blood pressure in the offspring. The aim of the present study was to investigate the associations of maternal first-trimester dietary intake with blood pressure in children at the age of 6 years. We assessed first-trimester maternal daily dietary intake by a FFQ and measured folate, homocysteine and vitamin B₁₂ concentrations in the blood, in a population-based prospective cohort study among 2863 mothers and children. Childhood systolic and diastolic blood pressure was measured using a validated automatic sphygmomanometer. First-trimester maternal daily intake of energy, fat, protein and carbohydrate was not associated with childhood blood pressure. Furthermore, maternal intake of micronutrients was not associated with childhood blood pressure. Also, higher maternal vitamin B₁₂ concentrations were associated with a higher diastolic blood pressure (0·31 mmHg per standard deviation increase in vitamin B₁₂ (95% CI 0·06, 0·56)). After taking into account multiple testing, none of the associations was statistically significant. Maternal first-trimester folate and homocysteine concentrations were not associated with childhood blood pressure. The results from the present study suggest that maternal Fe intake and vitamin B₁₂ concentrations during the first trimester of pregnancy might affect childhood blood pressure, although the effect estimates were small and were not significant after correction for multiple testing. Further studies are needed to replicate these findings, to elucidate the underlying mechanisms and to assess whether these differences in blood pressure persist in later life.

The aim of the study was to describe the sonographic findings of hepatobiliary fascioliasis with extrahepatic expansion and ectopic lesions. The study included 45 patients with fascioliasis. All diagnoses were confirmed via serologic enzyme-linked immunosorbent assays. Sonographic findings in the hepatobiliary system, extrahepatic expansion, and ectopic lesions were defined. The most common hepatic lesions were subcapsular localized, small, confluent, multiple hypoechoic nodules with poorly defined borders. We also detected ectopic lesion in 5 patients (11.1%) and live parasites in the gallbladder and bile duct in 11 (24.4%). The large spectrum of entities in the differential diagnosis of hepatobiliary fascioliasis may lead to misdiagnosis and incorrect treatment. However, the diagnosis can be made when the characteristic sonographic features are seen, such as heterogeneity of the liver with multiple poorly defined hypoechoic-isoechoic lesions and multiple echogenic nonshadowing particles in the gallbladder or common bile ducts. Nonetheless, the differential diagnosis of fascioliasis versus other hepatic lesions may still be difficult. In these situations, pathologic confirmation should be performed to exclude the possibility of malignancy. © 2013 by the American Institute of Ultrasound in Medicine.

Objective: To examine the association between the phthalate exposure in the first trimester and fasting blood glucose level or gestational diabetes mellitus (GDM) in the third trimester in pregnant women. Methods: A total of 3 474 pregnant women, receiving their prenatal examination in Ma' anshan Maternal and Child Health-Care Hospital of Anhui province, were selected from May 2013 to September 2014. Questionnaires were used to collect the information about their socio-demographic characteristics, clinical characteristics and GDM diagnostic results in the first, second and third trimesters. Urine samples and fasting venous blood samples were collected. Concentrations of 7 kinds of phthalate metabolites in urine samples were detected by solid phase extraction-high performance liquid chromatography-tandem mass spectrometry (SPE-HPLC-MS/MS), and multiple linear regression model was used for statistical analyses. Logistic regression analysis on the risk of the first trimester phthalate exposure for GDM in the third trimester was conducted. Results: The prevalence of GDM in this study was 12.8%, monomethyl phthalate (MMP), monoethyl phthalate (MEP), mono-n-butyl phthalate (MBP), monobenzyl phthalate (MBzP) and mono-(2-ethyl-5-oxohexyl) phthalate (MEHHP) exposure levels were positively correlated with the fasting blood glucose level in the third trimester ( P levels were negatively correlated with the fasting blood glucose level in the third trimester ( P blood glucose level in both normal group and GDM group. However, MMP, MEP, MBP, MBzP, MEHP and MEOHP exposure levels had influences on the third trimester fasting blood glucose level in normal group but not in GDM group. MMP and MBP exposure might increase the risk of GDM, but MEOHP exposure might reduce the risk of GDM. Conclusion: The phthalate exposure in the first trimester might be associated with the fasting blood glucose level in the third trimester, MMP, MEP, MBP, MBzP and MEHHP concentrations were positively

To analyse the sequential sonographic findings of cystic PVL and to evaluate relationship between sonographic grading of PVL and patterns of neurologic outcomes. Authors have retrospectively analysed the sequential sonographic findings of 36 cases of PVL in the preterm neonates. Initial sonographic features done within 3 days of life were divided into 3 patients such as normal, localized, and diffuse hyperechogenic flare. Grading of PVL confirmed by follow-up studies was classified as involvement of one lobe (grade 1), two lobes (grade 2) and more than extent of grade 2 (grade 3). The relationship between sonographic grading of leukomalacia and later neurologic outcomes were also analysed. Initial sonographic patterns according to grading of PVL were normal pattern in seven of nine (77.8%) of grade 1, diffuse hyperechogenic flares in five of eight cases of grade 2 and in 13 of 16 cases of grade 3. There was a significant difference between the grades and frequency of pattern of diffuse hyperechoic flare (p=0.021). Average detection timing of cystic PVL was 38.4{+-}18.9 days in grade 1, 29.8{+-}14 days in grade 2, and 19.1{+-}5.6 days in grade 3 with a significant statistical difference between the detection time and grades (p=0.037). Cerebral palsy has occurred in 62.5% of grade 1 and 100% of grade 2 and grade 3 (p=0.043). Frequency of spastic quadriplegia was higher in grade 3 (76.5%) than in grade 1 (25%) and grade 2 (12.5%) (p=0.001). Most of grade 1 cystic PVL revealed normal pattern of white matter echogenicity in initial ultrasonography and needed follow up examination over one month period. Spastic quadriplegia occured mainly in patients with grade 3 cystic PVL.

collection, maternal age and study center. MAIN RESULTS AND THE ROLE OF CHANCE Three metabolites of DEHP were significantly and inversely associated with both measures of boys' AGD. Associations (β, 95% confidence interval (CI)) between AGDAS and (log10) SpG-adjusted phthalate concentrations were: −1.12 (−2.16, −0.07) for mono-2-ethylhexyl phthalate (MEHP), −1.43, (−2.49, −0.38) for mono-2-ethyl-5-oxohexyl phthalate (MEOHP), and −1.28 (−2.29, −0.27) for mono-2-ethyl-5-hydroxyhexyl (MEHHP). Associations were of similar magnitude for AGDAP. Associations were weaker and not statistically significant for PW. No other phthalate metabolites were associated with any genital measurement in boys. No phthalate metabolites were associated with either AGD measure in girls. LIMITATIONS, REASONS FOR CAUTION Exposure assessment was based on a single first trimester urine sample, which may have introduced exposure misclassification. In addition, significant between-center differences suggest that this measurement is difficult to standardize. WIDER IMPLICATIONS OF THE FINDINGS Our findings are consistent with multiple rodent studies and most human studies which were far smaller. The data we report here suggest that even at current low levels, environmental exposure to DEHP can adversely affect male genital development resulting in reproductive tract changes that may impact reproductive health later in life. These findings have important implications for public policy since most pregnant women are exposed to this ubiquitous chemical.

Impaired fetal growth is associated with increased risks of kidney diseases in later life. Because human development rates are highest during the first trimester, this trimester may be a particularly critical period for kidney outcomes. We have therefore examined the association of fetal first trimester growth with kidney outcomes in childhood. This study was embedded in a prospective population-based cohort study among 1176 pregnant women and their children. We used fetal first trimester crown-length as the growth measure among mothers with a regular menstrual cycle and a known first day of the last menstrual period. At the childhood age of 6 (median 5.7-6.8) years, we measured combined kidney volume, microalbuminuria and estimated glomerular filtration rate (eGFR) based on serum creatinine and cystatin C concentrations. No consistent associations of fetal first trimester crown-rump length with childhood combined kidney volume, eGFR and microalbuminuria were observed. Compared to children with a fetal first trimester crown-rump length in the highest quintile, those in the lowest quintile had a larger childhood combined kidney volume (difference 5.32 cm 3 , 95 % confidence interval 1.06 to 9.57), but no differences in kidney function. Our results do not support the hypothesis that fetal first trimester growth restriction affects kidney size and function in childhood. Further studies are needed to focus on critical periods in early life for kidney function and disease in later life.

Advances in prenatal screening for Down syndrome: II first trimester testing, integrated testing, and future directions.

Science.gov (United States)

Benn, Peter A

2002-10-01

The acceptability of prenatal screening and diagnosis of Down syndrome is dependent, in part, on the gestational age at which the testing is offered. First trimester screening could be advantageous if it has sufficient efficacy and can be effectively delivered. Two first trimester maternal serum screening markers, pregnancy-associated plasma protein-A (PAPP-A) and free beta-human chorionic gonadotropin (beta-hCG), are useful for identifying women at increased risk for fetal Down syndrome. In addition, measurement of an enlarged thickness of the subcutaneous fluid-filled space at the back of the neck of the developing fetus (referred to as nuchal translucency or NT) has been demonstrated to be an indicator for these high-risk pregnancies. When these three parameters are combined, estimates for Down syndrome efficacy exceed those currently attainable in the second trimester. Women who are screen-positive in the first trimester can elect to receive cytogenetic testing of a chorionic villus biopsy. The first trimester tests could also, theoretically, be combined with the second trimester maternal serum screening tests (integrated screening) to obtain even higher levels of efficacy. There are, however, several practical limitations to first trimester and integrated screening. These include scheduling of testing within relatively narrow gestational age intervals, availability of appropriately trained ultrasonographers for NT measurement, risks associated with chorionic villus biopsy, and costs. There is also increasing evidence that an enlarged NT measurement is indicative of a high risk for spontaneous abortion and for fetal abnormalities that are not detectable by cytogenetic analysis. Women whose fetuses show enlarged NT, therefore, need first trimester counseling regarding their Down syndrome risks and the possibility of other adverse pregnancy outcomes. Follow-up ultrasound and fetal echocardiography in the second trimester are also indicated. First trimester

First-trimester screening for chromosomal abnormalities: advantages of an instant results approach.

Protocols that include first trimester screening for fetal chromosome abnormalities have become standard of care throughout the United States. Earlier screening allows for first trimester diagnostic testing in cases found to be at increased risk. However, first trimester screening requires coordination of the nuchal translucency ultrasound screening (NT) and biochemical screening, during early, specific, narrow, but slightly different gestational age ranges. Instant results can often be provided at the time of the NT ultrasound if preceded by the programs that perform the biochemical analyses; this optimizes the benefits of the first trimester approach while improving efficiency and communication with the patient. This article discusses the benefits and logistics of such an approach. Copyright 2010 Elsevier Inc. All rights reserved.

Early diagnosis of hygroma cervicis in a fetus. Sonographic, pulsed Doppler echographic and MRI findings

Energy Technology Data Exchange (ETDEWEB)

Date, Kenjiro; Nagai, Toru; Sera, Kyoko and others

1986-07-01

A fetus was diagnosed as having hygroma cervicis (HC) with sonography. Sonographic features at 23 weeks of gestation were symmetrical echo free spaces of the head suggestive of a giant solid tumor (HC) and single umbilical artery. When umbilical circulation of the single umbilical artery was examined using pulsed Doppler echography, high S/D ratios were seen. MRI clearly visualized a mass surrounding the head as an abnormal signal intensity. Pregnancy was terminated in the second trimester. A male stillborn baby weighing 1,440 g had multiple anomalies associated with cervical lymphangioma. Elevated amniotic and intracystic levels of AFP were not seen. A review of the literature shows the relationship between HC and Turner syndrome. However, because the present case was a male baby, hereditary disease may be related to the occurrence of HC.

Schwannomas are benign nerve sheath tumors composed of Schwann cells, which normally produce the insulating myelin sheath covering peripheral, cranial and autonomic nerves. Twenty-five to forty-five percent of all schwannomas occur in the head and neck region, but location of such tumors in the larynx is rarely observed. The present report is aimed at describing a clinical case of laryngeal schwannoma, with emphasis on sonographic findings. (author)

Subclinical hypothyroidism in the first trimester of pregnancy in North India

Directory of Open Access Journals (Sweden)

Jubbin Jagan Jacob

2013-01-01

Full Text Available Subclinical hypothyroidism based on population and trimester specific cut-offs is reported to complicate 1-2% of all pregnancies. Using the recent Endocrine Society guidelines of 2.5 mIU/L of Thyroid Stimulating Hormone as the upper level of normal in the first trimester the reported prevalence of subclinical hypothyroidism is much higher. Recent publications have also emphasized that there is considerable racial variation in the prevalence of thyroid disorders in pregnancy. Among published literature North Indian women appear to have the highest rates of subclinical hypothyroidism in the first trimester of pregnancy. More widespread use of universal screening and trimester specific ranges in pregnancy for thyroid hormonal assays will lead to a large number of North Indian women requiring treatment for thyroid disorders in pregnancy.

Many studies have indicated that the reduced folate carrier gene (SLC19A1) is associated with an increased risk of neural tube defects (NTDs). However, the interaction between the SLC19A1 gene variant and maternal fever exposure and NTD risk remains unknown. The aim of this study was to investigate whether the risk for NTDs was influenced by the interactions between the SLC19A1 (rs1051266) variant and maternal first trimester fever. We investigated the potential interaction between maternal first trimester fever and maternal or offspring SLC19A1 polymorphism through a population-based case-control study. One hundred and four nuclear families with NTDs and 100 control families with nonmal newborns were included in the study. SLC19A1 polymorphism was determined using polymerase chain reaction-restricted fragment length polymorphism. Mothers who had the GG/GA genotype and first trimester fever had an elevated risk of NTDs (adjusted odds ratio, 11.73; 95% confidence interval, 3.02-45.58) as compared to absence of maternal first trimester fever and AA genotype after adjusting for maternal education, paternal education, and age, and had a significant interactive coefficient (γ = 3.17) between maternal GG/GA genotype and first trimester fever. However, there was no interaction between offspring's GG/GA genotype and maternal first trimester fever (the interactive coefficient γ = 0.97) after adjusting for confounding factors. Our findings suggested that the risk of NTDs was potentially influenced by a gene-environment interaction between maternal SLC19A1 rs1051266 GG/GA genotype and first trimester fever. Maternal GG/GA genotype may strengthen the effect of maternal fever exposure on NTD risk in this Chinese population. © 2014 Wiley Periodicals, Inc.

Mental health problems are associated with women's reproductive decisions and predict poor mental health outcomes after abortion and childbirth. To study whether having a first-trimester induced abortion influenced the risk of psychiatric readmission and compare findings with readmission risk in women with mental disorders giving birth. Survival analyses were performed in a population-based cohort study merging data from the Danish Civil Registration System, the Danish Psychiatric Central Register, and the Danish National Hospital Register from January 1,1994, to December 31, 2007. Denmark. All women born in Denmark between 1962 and 1992 with a record of 1 or more psychiatric admissions at least 9 months before a first-time first-trimester induced abortion or childbirth. Main Outcome Measure  Readmission at a psychiatric hospital with any type of mental disorder from 9 months before to 12 months after a first-time first-trimester induced abortion or childbirth. Relative risk (RR) for readmission risk 9 to 0 months before a first-trimester induced abortion was 0.95 (95% CI, 0.73-1.23) compared with the first year after the abortion. This contrasts with a reduced risk of readmission before childbirth (RR, 0.56; 95% CI, 0.42-0.75) compared with the first year post partum. Proximity to previous psychiatric admission in particular predicted rehospitalization risks in both the abortion and the childbirth group. Risk of readmission is similar before and after first-time first-trimester abortion, contrasting with a marked increased in risk of readmission post partum. We speculate that recent psychiatric episodes may influence women's decisions to have an induced abortion; however, this decision does not appear to influence the illness course in women with a history of treated mental disorders.

Maternal leptin and body composition in the first trimester of pregnancy.

LENUS (Irish Health Repository)

Fattah, Chro

2012-02-01

BACKGROUND: Leptin is produced mainly by adipocytes. Levels are increased in women with obesity and during pregnancy. Increased levels are also associated with pregnancy complications such as, pre-eclampsia and gestational diabetes mellitus. OBJECTIVE: We studied what component of body composition correlated best with maternal leptin in the first trimester of pregnancy and, whether maternal leptin correlated better with visceral fat rather than fat distributed elsewhere. SUBJECTS AND METHODS: Women were recruited in the first trimester. Maternal adiposity was measured using body mass index and advanced bioelectrical impedance analysis. Maternal leptin was measured using an enzyme-linked immunosorbent assay technique. RESULTS: Of the 100 subjects studied, the mean leptin concentration was 37.7 ng\\/ml (range: 2.1-132.8). Leptin levels did not correlate with gestational age in the first trimester, maternal age, parity or birth weight. Serum leptin correlated positively with maternal weight and body mass index, and with the different parameters of body composition. On multiple regression analysis, serum leptin correlated with visceral fat but not fat distributed elsewhere. CONCLUSIONS: Visceral fat is the main determinant of circulating maternal leptin in the first trimester of pregnancy. This raises the possibility that maternal leptin in early pregnancy may be a marker for the development of metabolic syndrome, including diabetes mellitus.

Nutritional exposures during in utero development may have long-lasting consequences for postnatal renal health. Animal studies suggest that specifically maternal dietary protein intake during pregnancy influences childhood kidney function. We examined the associations of total, animal, and vegetable maternal protein intake during pregnancy with kidney volume and function in school-aged children. This study was conducted in 3650 pregnant women and their children who were participating in a population-based cohort study from early life onward. First-trimester energy-adjusted maternal protein intake was assessed with a food-frequency questionnaire. At the child's age of 6 y, we assessed kidney volume, estimated glomerular filtration rate (eGFR) using serum creatinine and cystatin C concentrations, and microalbuminuria using urine albumin:creatinine ratios. First-trimester maternal total protein intake was associated with a higher childhood creatinine-based eGFR (difference: 0.06 mL × min(-1) × 1.73 m(-2); 95% CI: 0.01, 0.12 mL · min(-1) · 1.73 m(-2) per gram of protein intake). This association was mainly driven by vegetable protein intake (0.22 mL × min(-1) × 1.73 m(-2); 95% CI: 0.10, 0.35 mL · min(-1) · 1.73 m(-2) per gram of vegetable protein intake). These associations were not explained by protein intake in early childhood. First-trimester maternal protein intake was not significantly associated with childhood kidney volume, cystatin C-based eGFR, or the risk of microalbuminuria. Our findings suggest that higher total and vegetable, but not animal, maternal protein intake during the first trimester of pregnancy is associated with a higher eGFR in childhood. Further follow-up studies are needed to investigate whether maternal protein intake in early pregnancy also affects the risk of kidney diseases in later life. © 2015 American Society for Nutrition.

Clinical differentiation of the various pathological conditions affecting scrotal contents can be difficult. The superficial location of scrotum is suited for sonographic examination. March, 1984 to december, 1987 authors experienced 23 cases of the inflammatory and tumorous condition, which were confirmed by operation and clinical follow up. The results are as follows : 1. Sonographic examination is safe, noninvasive, and useful in screening test of scrotum. 2. Sonography is useful for the confirmation of complicated epididymitis. 3. In palpable mass cases, sonography can differentiate intratesticular and extratesticular lesions. 4. Sonography is useful for detection of primary tumor in clinically uncertain conditions. 5. In epididymitis, sonography shows enlargement and decreased echogenecity of epididymis, reactive hydrocele, and thickening of scrotal wall. 6. In testicular tumor : Seminoma shows hypoechoic solid mass lesion with enlargement. Embryonal cell carcinoma shows ill defined hypoechoic testicular enlargement. Rhabdomyosarcoma shows ill defined hypoechoic mass with central necrosis. Metastatic testicular tumor shows bilaterallity and ill defined abnormal echogenecity, more older age distribution

Recent mammographic equipment have been of good quality and yielded high diagnostic accuracy for the detection of breast cancer. However, negative mammogram does not necessarily rule out breast cancer. Therefore were viewed cause of false negative mammography in confirmed breast cancer to improve diagnostic accuracy and for adequate clinical approach. We reviewed 19 cases of confirmed breast cancer, which showed false negative mammography with positive sonographic findings. Retrospective analysis was done by correlating the patient's age, sonographic finding and mass size, mammographic breast pattern and cause of false negative mammogram, and clinical symptoms. Among the 5 patients below 35 years in age, mass was not visible due to dense breast in 4 and due to small size in 1 case. In 14 patients over 35 years in age, 11 had normal mammographic findings, 4 had dense breast, and 7 had small sized mass. Remaining 3 cases showed asymmetric density in 2 and architecture distortion in 1 case. All showed mass lesion in sonography : ill defined malignant appearance in 14,well defined malignant appearance in 2, and well defined benign in 3 cases. Negative mammogram should be correlated with sonography in case of dense breast, below 35 years in age with palpable mass and under risk for breast cancer

Full Text Available To address the lack of insights into the engagement of tertiary students to manage knowledge at a course level, a knowledge management approach is proposed to allow students to interact with lecturers inside and outside a large lecture hall to create, disseminate, use and evaluate knowledge. The proposed approach was applied to an undergraduate business computing related course conducted at the offshore campus of an Australian university in the third trimester of 2012. The proposed KM approach was evaluated using quantitative analysis. The findings show that the majority of the students agreed that the computerized tool (Facebook could enhance their learning experience by allowing students to ask for, share, discuss, and extend knowledge. In particular, the KM approach provided additional channels and platforms for the first-trimester students who were passive and preferred not to seek help from lecturers directly for cultural reasons.

A decrease of insulin-like growth factor-I levels (IGF-I) has been reported during the first trimester of pregnancy in women with acromegaly before the secretion of placental growth hormone (GH) progressively increases IGF-1 concentration. To evaluate variations of concentrations of IGF-1, insulin-like growth factor (IGF)-binding protein-3 (IGF-BP3) and GH during the first trimester of pregnancy in women with normal somatotroph function. Sixteen women (median age 31 years) with as who were followed for benign thyroid disorders (n = 15) or prolactin-secreting microadenoma (n = 1) were evaluated before and in the first trimester of pregnancy. Serum concentrations of GH, IGF-1, IGF-BP3, TSH and estradiol (E2) were measured before and in the first trimester (5.4 ± 2.2 weeks of gestation). Before pregnancy, somatotroph and thyroid functions (median TSH 1.2 mU/L) were normal in all women. At the first trimester IGF-1 levels decreased significantly (before = 210 ng/mL, first trimester = 145 ng/mL, p function, IGF-1 levels decrease in the first trimester of pregnancy without changes in GH or IGF-BP3 levels. These results confirm liver resistance to GH as a consequence of the physiological increase of estrogens during the first trimester.

In this report, we present a rare case of primary signet-ring cell carcinoma of the appendix in a 51-year-old woman with right lower quadrant pain. Since non-specific concentric appendiceal wall thickening was found in a radiologic evaluation, it was misdiagnosed as non-tumorous appendicitis. An in-depth examination of the correlation between sonographic and histopathologic findings demonstrated that a single markedly thickened hypoechoic layer was well correlated with the diffuse infiltration of tumor cells in both the submucosal and muscle layers. If this sonographic finding is observed in certain clinical settings, such as potential ovarian and peritoneal metastasis, submucosal infiltrative tumors, including signet-ring cell carcinoma, should be considered in the differential diagnosis.

We adopted a descriptive and correlational research design and collected data from 261 pregnant women during their first trimester in southern Taiwan using structured questionnaires. Results showed that (1 stress was significantly and positively correlated with Yang-Xu, Yin-Xu, and Tan-Shi-Yu-Zhi constitutions, respectively; (2 Yin-Xu and Tan-Shi-Yu-Zhi constitutions had significant correlations with all symptoms of discomfort, while Yang-Xu had significant correlations with all symptoms of discomfort except for “running nose”; (3 Tan-Shi-Yu-Zhi constitution and stress were two indicators for “fatigue”; Tan-Shi-Yu-Zhi was the indicator for “nausea”; Yang-Xu and Yin-Xu were indicators for “frequent urination.” Our findings also indicate that stress level affects constitutional changes and that stress and constitutional change affect the incidence of discomfort. This research can help healthcare professionals observe these discomforts and provide individualized care for pregnant women, to nurture pregnant women into neutral-type constitution, minimize their levels of discomfort, and promote the health of the fetus and the mother.

2002-01-01

AIM: The aim of this study was to describe the contribution of mammographic and sonographic findings to the discrimination of typical and atypical histopathologic groups of medullary carcinomas of the breast. MATERIALS AND METHODS: Imaging findings were retrospectively assessed in 33 women with medullary carcinomas (15 typical medullary carcinomas and 18 atypical medullary carcinomas) identified during pre-operative mammography. Twenty-nine of these women also had ultrasound and these findings were reviewed. RESULTS: Mammography showed a well circumscribed mass in 10 of the 15 (67%) typical medullary carcinomas and in four of the 17 (24%) atypical medullary carcinomas (P < 0.02). One small tumour in a woman with atypical medullary carcinoma was missed on mammography and was shown only on sonography. Sonographically, an irregular margin surrounding the whole mass or part of it was seen in three out of 14 (21%) patients with typical medullary carcinoma and in nine out of 15 (60%) patients with atypical medullary carcinomas (P < 0.05). Posterior acoustic shadowing was more often observed in the typical medullary carcinoma group than in atypical medullary carcinoma and the difference was found to be statistically significant (P < 0.05). None of the other mammographic and sonographic findings were sufficiently characteristic to allow for a differentiation between two groups. CONCLUSION: When typical medullary carcinomas were compared with atypical medullary carcinomas according to imaging features, they tended to be well circumscribed masses on both mammography and sonography, and a posterior acoustic shadow was not found on sonography. However, the imaging findings in these two subgroups often resembled each other and histopathology will always be required to confirm the diagnosis. Yilmaz, E. et al. (2002)

Full Text Available Objective To evaluate the efficacy of first trimester combined screening for Down's syndrome in Northern Finland during the first 10 years of practice. Methods During 1 January 2002 to 31 December 2011, 47,896 women participated voluntarily in combined screening during first trimester. The risk cutoff was 1:250. The study period was divided into two time periods; 2002-2006 and 2007-2011. Results During the first half of the study period, the detection rate (DR was 77.3% with a 4.9% false-positive rate (FPR. During the latter half, the DR was 77.1% with a 2.8% FPR. Conclusions An important issue is the number of invasive procedures needed to detect one case of Down's syndrome. The screening performance improved markedly in the latter five years period since the FPR lowered from 4.9% to 2.8% and the number of invasive procedures needed to detect one case of Down's syndrome lowered from 15 to 11.

Background: Gestational diabetes mellitus (GDM) is increasing partly due to the obesity epidemic. Adipocytokines have thus been suggested as first trimester screening markers for GDM. In this study we explore the associations between body mass index (BMI) and serum concentrations of adiponectin......, leptin, and the adiponectin/leptin ratio. Furthermore, we investigate whether these markers can improve the ability to screen for GDM in the first trimester. Methods: A cohort study in which serum adiponectin and leptin were measured between gestational weeks 6+0 and 14+0 in 2590 pregnant women...

To examine risks for major structural birth defects in infants after first trimester inactivated influenza vaccine (IIV) exposures. In this observational study, we used electronic health data from 7 Vaccine Safety Datalink sites to examine risks for selected major structural defects in infants after maternal IIV exposure. Vaccine exposures for women with continuous insurance enrollment through pregnancy who delivered singleton live births between 2004 and 2013 were identified from standardized files. Infants with continuous insurance enrollment were followed to 1 year of age. We excluded mother-infant pairs with other exposures that potentially increased their background risk for birth defects. Selected cardiac, orofacial or respiratory, neurologic, ophthalmologic or otologic, gastrointestinal, genitourinary and muscular or limb defects were identified from diagnostic codes in infant medical records using validated algorithms. Propensity score adjusted generalized estimating equations were used to estimate prevalence ratios (PRs). We identified 52 856 infants with maternal first trimester IIV exposure and 373 088 infants whose mothers were unexposed to IIV during first trimester. Prevalence (per 100 live births) for selected major structural birth defects was 1.6 among first trimester IIV exposed versus 1.5 among unexposed mothers. The adjusted PR was 1.02 (95% CI 0.94-1.10). Organ system-specific PRs were similar to the overall PR. First trimester maternal IIV exposure was not associated with an increased risk for selected major structural birth defects in this large cohort of singleton live births.

Vaginal bleeding is not uncommon in the first trimester of pregnancy. The majority of such patients will have a normal intrauterine pregnancy (IUP), a nonviable IUP, or an ectopic pregnancy. Ultrasound (US) is the primary imaging modality in evaluation of these patients. US, along with clinical observations and serum human chorionic gonadotropin levels, can usually distinguish these causes. Although it is important to diagnose ectopic pregnancies and nonviable IUPs, one should also guard against injury to normal pregnancies due to inappropriate treatment with methotrexate or surgical intervention. Less common causes of first trimester vaginal bleeding include gestational trophoblastic disease and arteriovenous malformations. Pulsed methods of Doppler US should generally be avoided in the first trimester when there is a normal, or a potentially normal, IUP. Once a normal IUP has been excluded, Doppler US may be useful when other diagnoses such as retained products of conception or arteriovenous malformations are suspected. MRI may occasionally be helpful as a problem-solving tool. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment. Copyright © 2018 American College of Radiology.

Prenatal diagnosis of sirenomelia in the first trimester: A case report.

Science.gov (United States)

Ceylan, Yasin; Doğan, Yasemin; Özkan Özdemir, Sebiha; Yücesoy, Gülseren

2016-03-01

Sirenomelia or "mermaid syndrome" is a rare congenital syndrome characterized by the anomalous development of the caudal region of the body. We present a case of sirenomelia diagnosed in the first trimester using two-dimensional and three-dimensional ultrasonographic examination. A nulliparous woman aged thirty years was referred to our perinatology unit for evaluation because of oligohydramnios at 12 weeks of gestation. Her medical history was unremarkable. There was no family history of genetic abnormalities. We identified a single lower extremity and severe oligohydramnios, which are characteristics of sirenomelia. Sirenomelia, a developmental defect involving the caudal region of the body, is associated with several internal visceral anomalies. Sirenomelia is fatal in most cases due to the characteristic pulmonary hypoplasia and renal agenesia. Prenatal diagnosis of sirenomelia may be difficult in the second or third trimester because of the severe oligohydramnios; it should be easier to diagnose sirenomelia in the first trimester.

Predisposing Factors to Abnormal First Trimester Placentation and the Impact on Fetal Outcomes

Normal placentation during the first trimester sets the stage for the rest of pregnancy and involves a finely orchestrated cellular and molecular interplay of maternal and fetal tissues. The resulting intrauterine environment plays an important role in fetal programming and the future health of the fetus, and is impacted by multiple genetic and epigenetic factors. Abnormalities in placentation and spiral artery invasion can lead to ischemia, placental disease and adverse obstetrical outcomes including preeclampsia, intrauterine growth restriction, and placental abruption. Although first trimester placentation is affected my multiple factors, preconception environmental influences such as mode of conception, including assisted reproductive technologies which result in fertilization in vitro and intrauterine influences due to sex differences are emerging as potential significant factors impacting first trimester placentation.

Plasma cross-gestational sphingolipidomic analyses reveal potential first trimester biomarkers of preeclampsia.

Directory of Open Access Journals (Sweden)

Full Text Available Preeclampsia (PE is a gestational disorder, manifested in the second half of pregnancy by maternal hypertension, proteinuria and generalized edema. PE is a major cause of maternal and fetal morbidity and mortality, accounting for nearly 40% of all premature births worldwide. Bioactive sphingolipids are emerging as key molecules involved in etiopathogenesis of PE, characterized by maternal angiogenic imbalance and symptoms of metabolic syndrome. The aim of this study was to compare the cross-gestational profile of circulating bioactive sphingolipids in maternal plasma from preeclamptic (PE versus normotensive control (CTL subjects with the goal of identifying sphingolipids as candidate first trimester biomarkers of PE for early prediction of the disease.A prospective cohort of patients was sampled at the first, second and third trimester of pregnancy for each patient (11-14, 22-24, and 32-36 weeks´ gestation. A retrospective stratified study design was used to quantify different classes of sphingolipids in maternal plasma. We used a reverse-phase high-performance liquid chromatography-tandem mass spectrometry (HPLC-ESI-MS/MS approach for determining different sphingolipid molecular species (sphingosine-1-phosphate (S1P, dihydro-sphingosine-1-phosphate (DH-S1P, sphingomyelins (SM and ceramides (Cer in cross-gestational samples of human plasma from PE (n = 7, 21 plasma samples across pregnancy and CTL (n = 7, 21 plasma samples across pregnancy patients.Plasma levels of angiogenic S1P did not change significantly in control and in preeclamptic patients´ group across gestation. DH-S1P was significantly decreased in second trimester plasma of PE patients in comparison to their first trimester, which could contribute to reduced endothelial barrier observed in PE. The major ceramide species (Cer 16:0 and Cer 24:0 tended to be up-regulated in plasma of control and PE subjects across gestation. The levels of a less abundant plasma ceramide species (Cer

Increased nuchal translucency (NT) is present in about 50% of cases with trisomy 21. Very often the nuchal edema evolves in hydrops fetalis until the second trimester. Furthermore, a small amount of cases with a normal NT and trisomy 21 exhibit anatomical anomalies. We present a case of a 21-year-old woman, nulliparous, with a history of one termination of pregnancy and a smoking quitter. The prenatal control was negative for TORCH. During the first trimester scan on the 13th week, the NT was found 2.7 mm, the ductus venosus Doppler was normal, and the nasal bone was present. Hydrops fetalis was present though, and the parents were advised for chorionic villus sampling (CVS), but they opted for termination of pregnancy. The molecular control by QF-PCR showed normal karyotype for 13 and 18, a male fetus, but non-dysjunction trisomy 21 was present. Parental karyotype was advised, but they refused to perform it. One year later, the couple had another pregnancy. On the 12th week scan, the NT was found 1.0 mm, the ductus venosus Doppler was normal, and the nasal bone was present, but encephalocele was also found, and the parents consented again for termination of pregnancy. The new molecular control showed the same results. This time parental karyotype was performed. The father had a normal one, whereas the mother showed reversed p11 and q13 zones in chromosome 2. Genetical consulting and prenatal cytological control was advised in before next pregnancy. PMID:25883716

To validate a prediction model for successful vaginal birth after Cesarean delivery (VBAC) based on sonographic assessment of the hysterotomy scar, in a Swedish population. Data were collected from a prospective cohort study. We recruited non-pregnant women aged 18-35 years who had undergone one previous low-transverse Cesarean delivery at ≥ 37 gestational weeks and had had no other uterine surgery. Participants who subsequently became pregnant underwent transvaginal ultrasound examination of the Cesarean hysterotomy scar at 11 + 0 to 13 + 6 and at 19 + 0 to 21 + 6 gestational weeks. Thickness of the myometrium at the thinnest part of the scar area was measured. After delivery, information on pregnancy outcome was retrieved from hospital records. Individual probabilities of successful VBAC were calculated using a previously published model. Predicted individual probabilities were divided into deciles. For each decile, observed VBAC rates were calculated. To assess the accuracy of the prediction model, receiver-operating characteristics curves were constructed and the areas under the curves (AUC) were calculated. Complete sonographic data were available for 120 women. Eighty (67%) women underwent trial of labor after Cesarean delivery (TOLAC) with VBAC occurring in 70 (88%) cases. The scar was visible in all 80 women at the first-trimester scan and in 54 (68%) women at the second-trimester scan. AUC was 0.44 (95% CI, 0.28-0.60) among all women who underwent TOLAC and 0.51 (95% CI, 0.32-0.71) among those with the scar visible sonographically at both ultrasound examinations. The prediction model demonstrated poor accuracy for prediction of successful VBAC in our Swedish population. Copyright © 2017 ISUOG. Published by John Wiley & Sons Ltd. Copyright © 2017 ISUOG.

Sirenomelia sequence is a rare lethal pattern of congenital anomalies characterized by a number of hallmark skeletal anomalies, including fusion of the lower extremities or a single lower limb, bilateral renal agenesis or dysgenesis with absent or hypoplastic renal arteries, oligohydramnios, and the presence of aberrant vasculature. The etiology is still controversial. Prognosis is very poor, with the babies being stillborn or succumbing soon after birth. In the second trimester, oligohydramnios due to renal agenesis makes the diagnosis of sirenomelia difficult. Conversely, in the first trimester, the amniotic fluid volume is usually normal, unrelated to the fetal urine production. Therefore, a first-trimester or early second trimester anatomic survey of the fetus is proposed as preferable and more accurate for the diagnosis of this rare anomaly. In this article, we report a case of sirenomelia detected by two- and three-dimensional ultrasound in the 11th week of gestation and the associated literature is discussed.

While the incidence of back pain during pregnancy has been shown to be high, few studies have investigated postural changes that occur during pregnancy and their relationship to back pain. The purpose of this study was to determine if posture and back pain changed from the first to the third trimester of pregnancy and whether there was a relationship between the two. Twelve healthy women who were having uncomplicated pregnancies participated in the study. During the first and third trimesters, each subject had their standing posture and back pain assessed by a Metrecom Skeletal Analysis System and a 0- to 10-cm line pain scale, respectively. Repeated measures analysis of variance and Pearson correlation coefficients were calculated on or between back pain and nine posture variables and revealed significant increases in third trimester back pain and postures compared with first trimester back pain (p postures for lumbar angle (p change in posture and back pain. These results suggest that in the standing position the lumbar lordosis and sagittal pelvic tilt increased and head position become more posterior as women progressed from the first trimester to the last trimester of pregnancy. These postural changes, however, were not related to back pain. This suggests that many of the posture-correcting clinical exercise regimens given to pregnant women need to be investigated.

Full text: Accurate pregnancy dating is vital to obstetric management. However, first trimester fetal charts commonly used in Australia rely on data reported more than three decades ago. This study reports first trimester dating and growth charts for crown-rump length between 5 and 14 weeks of gestation and biparietal diameter between 9 and 14 weeks of gestation on an Australia population using modern real-time ultrasound equipment. All consenting eligible women attending a large Sydney clinic for first trimester ultrasound between March 2005 and December 2006 were recruited. Measurements were carried out to Australasian Society for Ultrasound in Medicine standard protocols. Statistical analyses were undertaken using polynomial regression models and thorough diagnostic checks made. Overall 396 eligible women consented to the study, with 268 between 9 and 14 weeks of gestation. The average participant age was 34 years (range 22-45 years), 371 and all yielded valid biometry measurements. Equations, means and 90% reference intervals for crown-rump length measurements and biparietal diameter measurements were derived using polynomial regression models. Thorough residual and diagnostic checks were made. Once validated by others, we believe they will warrant consideration for use by Australasian Society for Ultrasound in Medicine.

Introduction : Visual search is a task that humans perform in everyday life. Whether it involves looking for a pen on a desk or a mass in a mammogram, the cognitive and perceptual processes that underpin these tasks are identical. Radiologists are experts in visual search of medical images and studies on their visual search behaviours have revealed some interesting findings with regard to diagnostic errors. In Australia, within the modality of ultrasound, sonographers perform the diagnostic scan, select images and present to the radiologist for reporting. Therefore the visual task and potential for errors is similar to a radiologist. Our aim was to explore and understand the detection, localisation and eye-gaze behaviours of a group of qualified sonographers. Method : We measured clinical performance and analysed diagnostic errors by presenting fifty sonographic breast images that varied on cancer present and degree of difficulty to a group of sonographers in their clinical workplace. For a sub-set of sonographers we obtained eye-tracking metrics such as time-to-first fixation, total visit duration and cumulative dwell time heat maps. Results : The results indicate that the sonographers' clinical performance was high and the eye-tracking metrics showed diagnostic error types similar to those found in studies on radiologist visual search. Conclusion : This study informs us about sonographer visual search patterns and highlights possible ways to improve diagnostic performance via targeted education.

Breast carcinoma is uncommon in women under 35 years of age and may be difficult to detect because clinically palpable masses are usually benign, and mammography may be limited by dense parenchyma. The purpose of this work was to evaluate the mammographic findings in young patients with breast cancer and the efficacy of mammography in identifying these lesions. During an 8-year period, 100 breast cancers were diagnosed mammography and sonography were performed in 678% and 19% of patients, respectively; mammography demonstrated the lesion in 90% of cases. Mammographic and sonographic findings are presented

In this series, we aimed to describe the sonographic findings of chondral avulsion fractures that develop concomitant with lateral ankle ligament injury in children. We performed stress sonography during a manual anterior drawer stress procedure of the ankle in 9 skeletally immature patients who had recently had a lateral ankle sprain. Echo videos were obtained through the course of treatment, and all videos were reviewed. We elucidated the common features of chondral avulsion fractures of the lateral ankle ligaments in the children. The features of avulsion fractures on conventional sonography included absence of a fracture with hyperechoic spots (sonographic occult fracture type), cortical discontinuity with hyperechoic spots (cortical disruption fracture type), fracture line in the cortical bone (double-line fracture type), and a step-off deformity of the cortical bone with cartilage (displaced fracture type). In contrast, the features of chondral fractures on stress sonography included abnormal motion of the chondral lesions and mobility/fluidity of hyperechoic spots along the chondral fracture site. The presence of hyperechoic spots around the chondral lesion is an important sonographic sign for diagnosing chondral fractures concomitant with ankle lateral ligament injury. Hence, we believe that stress sonography should be considered for the detection of chondral fractures concomitant with radiographically negative ankle lateral ligament injuries in skeletally immature patients with lateral ankle pain and ankle sprains, if hyperechoic spots are present in the cartilage of the distal fibula. © 2017 by the American Institute of Ultrasound in Medicine.

We reviewed the sonographic features of Morel-Lavalle'e lesions by correlating the US image findings with a lesion's age. We obtained the sonography reports of 20 Morel-Lavalle'e lesions of the hip and extremities from 18 patients with a history of trauma. The US images were reviewed to characterize the echogenicity, shape, homogeneity, margins, location and size of the lesions. The results were correlated with the age of the lesions and the clinical histories. All the Morel-Lavalle'e lesions were hypoechoic or anechoic fluid collections located between the subcutaneous fat and the underlying fascia. Regarding the shape of the fluid collections, the lobular shaped lesions were all less than 21 days for the lesion's age, and the flat fluid collections were all greater than 1 month of age. Regarding the homogeneity, the heterogeneous fluid collections were all less than 25 days of age, and the homogeneous fluid collections were all greater than 1 month of age. A Morel-Lavalle'e lesion is seen as a posttraumatic fluid collection in the potential space between the subcutaneous fat and the underlying fascia on an ultrasound examination. Acute Morel-Lavalle'e lesions tended to be heterogeneous and lobular, and they became more homogeneous and flat in shape as the lesions evolved. Awareness of these imaging findings will help us to properly diagnose Morel- Lavalle'e lesions

To assess the potential of first-trimester sonography in the detection of fetal abnormalities using an extended protocol that is achievable with reasonable resources of time, personnel and ultrasound equipment. This was a prospective two-center 2-year study of 5472 consecutive unselected pregnant women examined at 12 to 13 + 6 gestational weeks. Women were examined using an extended morphogenetic ultrasound protocol that, in addition to the basic evaluation, involved a color Doppler cardiac sweep and identification of early contingent markers for major abnormalities. The prevalence of lethal and severe malformations was 1.39%. The first-trimester scan identified 40.6% of the cases detected overall and 76.3% of major structural defects. The first-trimester detection rate (DR) for major congenital heart disease (either isolated or associated with extracardiac abnormalities) was 90% and that for major central nervous system anomalies was 69.5%. In fetuses with increased nuchal translucency (NT), the first-trimester DR for major anomalies was 96%, and in fetuses with normal NT it was 66.7%. Most (67.1%) cases with major abnormalities presented with normal NT. A detailed first-trimester anomaly scan using an extended protocol is an efficient screening method to detect major fetal structural abnormalities in low-risk pregnancies. It is feasible at 12 to 13 + 6 weeks with ultrasound equipment and personnel already used for routine first-trimester screening. Rate of detection of severe malformations is greater in early- than in mid-pregnancy and on postnatal evaluation. Early heart investigation could be improved by an extended protocol involving use of color Doppler. Copyright © 2013 ISUOG. Published by John Wiley & Sons Ltd.

To determine 1) the diagnostic accuracy requirements of first-trimester genetic sonography from the cost-benefit point of view and 2) the economic impact of first-trimester genetic sonography for the United States on the basis of the accuracy of previously published studies. A cost-benefit equation was developed on the basis of the hypothesis that the cost of chorionic villus sampling (CVS) in pregnant women with advanced maternal age (at least 35 years old) should be at least equal to the cost of genetic sonography with CVS used only for those with abnormal ultrasound results. The components of the equation included the diagnostic accuracy of genetic ultrasound (sensitivity and specificity for detecting Down syndrome), the costs of the CVS package and genetic ultrasound, and the lifetime cost of Down syndrome cases. First-trimester genetic sonography was found to be beneficial if the overall sensitivity for detecting Down syndrome was greater than 70%, and even then, the cost-benefit ratio depended on the corresponding false-positive rate. The required minimum ultrasound sensitivity varied according to the maternal age-specific prevalence of Down syndrome and ranged between 40% (for women 35 years old) to 96% (for women 44 years old). Of eight published cohorts using nuchal translucency thickness for genetic sonography, five had accuracies of genetic ultrasound compatible with net benefits. The benefits of first-trimester genetic sonography depend on its diagnostic accuracy. First-trimester genetic sonography has the potential for annual savings of 22 million dollars in the United States.

Maternal diet during pregnancy has been suggested to influence bone health in later life. We assessed the association of maternal first-trimester dietary intake during pregnancy with childhood bone mass. In a prospective cohort study in 2819 mothers and their children, we measured first-trimester daily energy, protein, fat, carbohydrate, calcium, phosphorus, and magnesium intakes by using a food-frequency questionnaire and homocysteine, folate, and vitamin B-12 concentrations in venous blood. We measured childhood total body bone mass by using dual-energy X-ray absorptiometry at the median age of 6.0 y. Higher first-trimester maternal protein, calcium, and phosphorus intakes and vitamin B-12 concentrations were associated with higher childhood bone mass, whereas carbohydrate intake and homocysteine concentrations were associated with lower childhood bone mass (all P-trend childhood bone mass. In the fully adjusted regression model that included all dietary factors significantly associated with childhood bone mass, maternal phosphorus intake and homocysteine concentrations most-strongly predicted childhood bone mineral content (BMC) [β = 2.8 (95% CI: 1.1, 4.5) and β = -1.8 (95% CI: -3.6, 0.1) g per SD increase, respectively], whereas maternal protein intake and vitamin B-12 concentrations most strongly predicted BMC adjusted for bone area [β = 2.1 (95% CI: 0.7, 3.5) and β = 1.8 (95% CI: 0.4, 3.2) g per SD increase, respectively]. Maternal first-trimester dietary factors are associated with childhood bone mass, suggesting that fetal nutritional exposures may permanently influence bone development.

2004-01-01

We report 6 cases of polysplenic syndrome diagnosed on prenatal sonography. The mean menstrual age at the time of presentation was 275 weeks (range 184 to 38 weeks). All cases were examined using level-II prenatal sonography. The sonographic findings of polysplenic syndrome were retrograde analyzed and compared to the autopsy or postnatal findings. Polysplenia was detected in 5 cases on the prenatal sonography. Associated cardiovascular anomalies were detected in all 6 cases, all of which had more than one anomaly, namely complete atrioventricular septal defect in two cases, double outlet right ventricle combined with rudimentary LV or mitral atresia in two cases and VSD and ASD in one case each. There were three cases of interrupted IVC with azygous continuation of the posterior thorax. Bradycardia was observed in 2 cases, one of which showed AV dissociation of rhythm. Visceral abnormalities were present in all cases and there were combined anomalies such as echogenic bowel, pelviectasia, horseshoe kidney, and posterior neck cystic hygroma and fetal hydrops. Four cases terminated pregnancy. The autopsy results of 2 cases were comparable to those of the prenatal sonography, however autopsies were not performed in 2 cases. One fetus near term was delivered and the baby subsequently underwent heart surgery and was still alive at the last follow-up. The remaining one case was lost to follow-up. If multiple fetal anomalies, including complex heart disease and polysplenia, are detected in the prenatal sonography, a diagnosis of polysplenic syndrome can be made. IVC interruption with azygous continuation can also be helpful in the diagnosis of polysplenic syndrome, and this can be observed by detecting the double vessel of the posterior thorax

2004-01-01

To evaluate the diagnostic accuracy of a diagnosis of acute appendicitis in pregnant women according to the trimester. A retrospective review was performed on 103 pregnant women who underwent sonography with clinically suspected acute appendicitis. The sonographic technique used involved either the graded compression or a non-compression method. All the sonograms were obtained after changing the patient's position and identifying the diseased appendix. The criterion for a sonographic diagnosis of acute appendicitis was the visualization of a non-compressible appendix with a maximal diameter ≥ 6 mm. The sonographic findings were correlated with the surgical findings and clinical follow-up. Acute appendicitis was confirmed by both the surgical and pathological findings in 48 out of 103 pregnant women. Ultrasound established the diagnosis in 34 of the 48 patients with proven appendicitis. There were false-positives in 2 patients and false-negatives in 14 patients. Among the 55 patients who had a normal appendix, 30 patients improved at the clinical follow-up and 25 patients had other intra-abdominal disorders. The diagnostic accuracy of the ultrasound was 94% in the first trimester, 81% in the second trimester, and 76% in the third trimester. The overall accuracy was found to be 84%, with a 71% sensitivity and a 96% specificity. No significant difference was found in the diagnostic accuracy of the ultrasound according to the trimester in which the acute appendicitis occurred. Therefore, regardless of the stage of gestation, sonography is a valuable procedure for diagnosing acute appendicitis

Human first-trimester trophoblast cells proliferate at low O2, but survival is compromised by oxidative stress, leading to uteroplacental insufficiency. The vasoactive drug, sildenafil citrate (Viagra, Sigma, St Louis, Missouri), has proven useful in reducing adverse pregnancy outcomes. An important biological function of this pharmaceutical is its action as an inhibitor of cyclic guanosine monophosphate (cGMP) phosphodiesterase type 5 activity, which suggests that it could have beneficial effects on trophoblast survival. To investigate whether sildenafil can prevent trophoblast cell death, human first-trimester villous explants and the HTR-8/SVneo cytotrophoblast cell line were exposed to hypoxia and reoxygenation (H/R) to generate oxidative stress, which induces apoptosis. Apoptosis was optimally inhibited during H/R by 350 ng/mL sildenafil. Sildenafil-mediated survival was reversed by l-NG-nitro-l-arginine methyl ester hydrochloride or cGMP antagonist, indicating a dependence on both nitric oxide (NO) and cGMP. Indeed, either a cGMP agonist or an NO generator was cytoprotective independent of sildenafil. These findings suggest a novel intervention route for patients with recurrent pregnancy loss or obstetrical placental disorders. PMID:25431453

Apart from the difficult differential diagnosis of hydatid liver disease, diagnostic problems may increase in chronic disease because of complications. Compression or infiltration of bile ducts is the most common complication occuring in 16%. Other complications are infiltration of adjacent organs and structures, for instance the right kidney and the diaphragm, or the (often iatrogenic) rupture of hydatid cysts with intraperitoneal spread. Preoperative sonographic diagnosis is important in influencing the surgical procedure.

The clinical introduction of first trimester aneuploidy screening uniquely challenges the informed consent process for both patients and providers. This study investigated key aspects of the decision-making process for this new form of prenatal genetic screening. Qualitative data were collected by nine focus groups that comprised women of different reproductive histories (N = 46 participants). Discussions explored themes regarding patient decision making for first trimester aneuploidy screening. Sessions were audio recorded, transcribed, coded, and analyzed to identify themes. Multiple levels of uncertainty characterize the decision-making process for first trimester aneuploidy screening. Baseline levels of uncertainty existed for participants in the context of an early pregnancy and the debate about the benefit of fetal genetic testing in general. Additional sources of uncertainty during the decision-making process were generated from weighing the advantages and disadvantages of initiating screening in the first trimester as opposed to waiting until the second. Questions of the quality and quantity of information and the perceived benefit of earlier access to fetal information were leading themes. Barriers to access prenatal care in early pregnancy presented participants with additional concerns about the ability to make informed decisions about prenatal genetic testing. The option of the first trimester aneuploidy screening test in early pregnancy generates decision-making uncertainty that can interfere with the informed consent process. Mechanisms must be developed to facilitate informed decision making for this new form of prenatal genetic screening.

Following the PRISMA guideline for systematic reviews, we performed a systematic search on the risk of major congenital malformations after first trimester in utero exposure to venlafaxine or duloxetine. We identified eight cohort...... studies reporting on the outcome upon in utero exposure to venlafaxine or duloxetine during the first trimester. The cumulated data for venlafaxine were 3186 exposed infants and 107 major malformations, resulting in a relative risk estimate and 95% confidence interval of 1.12 (0.......92-1.35). The corresponding data for duloxetine were 668 infants and 16 major malformations, resulting in a relative risk estimate and 95% confidence interval of 0.80 (0.46-1.29). First-trimester in utero exposure to venlafaxine is not associated with an increased risk of major congenital malformations. The amount of data...

A healthy 27-year-old pregnant woman underwent sonographic examination because her uterine size was large for 20 weeks' menstrual age. Sonograms showed short fetal limbs with hitchhiker thumbs and toes, thoracic scoliosis, clubbed feet, and polyhydramnios. The ossification of all bony structures appeared normal, and there was no evidence of fractures. On the basis of these sonographic findings, we diagnosed skeletal dysplasia and short-limbed dwarfism, most likely diastrophic dwarfism. We counseled the parents, and the pregnancy was continued. At 37 weeks menstrual age, the patient vaginally delivered a male infant that weighed 2,560 g. The infant survived with respiratory support during his first few days of life. Postnatal physical and radiologic examinations confirmed the prenatal diagnosis of diastrophic dwarfism. Sonography is the modality of choice for prenatal detection of diastrophic dwarfism.

The aim of this study is to determine whether there is a relationship between first trimester serum pregnancy-associated plasma protein A (PAPP-A) and free beta human chorionic gonadotropin (fβhCG) MoM values and placenta accreta in women who had placenta previa. A total of 88 patients with placenta previa who had first trimester aneuploidy screening test results were enrolled in the study. Nineteen of these patients were also diagnosed with placenta accreta. As probable markers of excessive placental invasion, serum PAPP-A and fβhCG MoM values were compared in two groups with and without placenta accreta. Patients with placenta accreta had higher statistically significant serum PAPP-A (1.20 versus 0.865, respectively, p = 0.045) and fβhCG MoM (1.42 versus 0.93, respectively, p = 0.042) values than patients without accreta. Higher first trimester serum PAPP-A and fβhCG MoM values seem to be associated with placenta accreta in women with placenta previa. Further studies are needed to use these promising additional tools for early detection of placenta accreta.

Full Text Available Background: Missed or inappropriately-treated splenic injury is a significant cause of preventable trauma-related death. Physical examination and abdominal ultrasonography are essential tools for early diagnosis of splenic injury. However, some injuries may not be accurately diagnosed by ultrasonography at initial evaluation. Aim: The aim of this study was to audit indications for splenectomy at the University College Hospital, Ibadan and to compare the intra-operative findings in trauma-related cases with the sonographic findings. Materials and Methods: We retrospectively reviewed all adult (12 years and older patients′ records who had splenectomy between July 2003 and June 2010. The data extracted included patient demographics and indications for splenectomy. In trauma cases, the mode of injury and vital signs at presentation, sonographic findings, and operation findings were recorded. The intervals between injury and sonography and duration to surgery were also noted respectively. Results: Eighty-four patients were reviewed in the 7-year review period. The male to female ratio was approximately 2:1. The ages ranged from 14 to 76 years with a peak incidence in the third decade. Elective indications for splenectomy were 14 (16.6%, while 70 (83.3% were emergency cases. Forty-four of the trauma-related patients had pre-operative abdominal ultrasound, of which 31 (70% was reported as sonographically normal prior to surgery, while the rest of the trauma-related cases were considered too ill for ultrasonography. Conclusion: Potentially significant injuries may be missed with screening sonography. For this reason, a physician must maintain a high index of suspicion and consider the patient′s clinical status or an alternative imaging modality in excluding a diagnosis of splenic injury.

In order to determine the significance of nuchal translucency thickness on the subsequent natural history of first-trimester fetuses with a chromosome translocation, seven consecutive cases diagnosed between 11 and 13 weeks of gestation were reviewed. Nuchal translucency measurements were successfully obtained before chorionic villus sampling (CVS) in all cases. Three fetuses had an unbalanced translocation and all were associated with increased nuchal translucency and multiple anomalies at the detailed second-trimester scan. There were no survivors in this group. The remaining four fetuses had a balanced translocation; all had normal nuchal translucency thickness and no structural anomalies were detected in the second trimester. Three of these fetuses were born at > or =35 weeks of gestation and were phenotypically normal. However, an unexpected single fetal demise occurred in a dichorionic twin pregnancy at 28 weeks of gestation. It is concluded that nuchal translucency measurements provide important prognostic information on pregnancy outcome in first-trimester fetuses with a chromosome translocation. In parents with a known balanced translocation, the detection of increased nuchal translucency at 11-14 weeks of gestation is associated with unbalanced translocations, structural anomalies and poor pregnancy outcome.

2009-01-01

Statutory agents have stipulated that research activity is a fundamental component of the healthcare professional's activity. Whilst the College of Radiographers have emphasised the importance of imaging personnel embracing this research ethos, there is little available data on the level of research activity within sonographic practice or on the factors that influence a sonographer's involvement in research activities. This work attempts to address these deficiencies. A questionnaire was sent to 300 UK-based sonographers of whom 218 responded (72%). The questionnaire was specifically designed to establish the level of involvement in research, the utilisation of research findings, attitudes towards research and perceived barriers to active research involvement. Responses were analysed investigating any correlations with the population demographics. The data collected showed the majority of sonographers (89%) were enthusiastic about research but with only 33% and 60% currently or previously performing research, respectively, and 73% using research findings to modify their clinical practice. Certain barriers to an active research involvement were shown, with 63%, 55% and 40% citing lack of time, education and collegial support, respectively. A range of statistical findings were linked to particular sonographer groups. The importance of good organisational structures and effective support from fellow health professionals was highlighted. The results confirm sonographers' appreciation of the benefits of research and it is suggested that if this enthusiasm is translated into effective research strategies, research output from ultrasound and other clinical departments should be enhanced.

To evaluate the results of screening for trisomy 21 by the combined risk of first trimester (as defined by the decree of June 23, 2009) in the Prima facie structure. Single center study involving all patients that were seen for first trimester screening at Prima facie with singleton living pregnancy, not obtained by embryo donation, between 1 January 2009 and 31 December 2014. Eighteen thousand two hundred and fifty-one patients were included, of which underwent screening for trisomy 21 by the combined risk. One thousand and forty-six (6.1%) had a calculated risk higher than 1/250. Seventy-five were affected by trisomy 21, of whom 65 in the high risk group. The sensitivity and specificity of screening are 86.7% and 94.4%. The median nuchal translucency was 0.98 MoM. Screening for trisomy 21 by calculating the combined risk of first trimester enabled to detect 86.7% of trisomy 21 with a false positive rate of 5.6%. Copyright © 2015 Elsevier Masson SAS.

The prevalence and causes of MSI amongst sonographers

International Nuclear Information System (INIS)

Morton, Becky; Delf, Penny

2008-01-01

The concept for this article came from the observation of sonographers at work and by reviewing the literature; it aims to consider the prevalence and causes of musculoskeletal injuries amongst sonographers. Emerging themes were analysed using the comparison of study results to verify and validate findings. Several important themes were identified in the literature: symptoms, prevalence and causes of musculoskeletal injury (MSI) among sonographers. The prevalence of MSI is apparently high; the average from the literature being 81%. However, many sonographers have not been diagnosed with musculoskeletal injuries, seeing their pain and discomfort as part of their job. Many areas of a sonographers' job have been reported as being possible causes of MSI. Posture, equipment, increased workload, and lack of breaks are just a few causes which are explored below

First-trimester fetal cardiac screening examinations in low-risk populations should not have to meet the specifications required for high-risk populations. Our aim was to evaluate a simplified fetal echocardiographic ('basic heart') examination for early detection of severe congenital heart defects in a low-risk population. This was a first-trimester national 'flash study', performed over a 2-week period. Each observer was requested to perform simplified echocardiography without modifying the time and methods deemed necessary for the routine first-trimester ultrasound examination, in fetuses with crown-rump length between 45 and 84 mm. This basic heart assessment used targeted cross-sections of the four-chamber view (4CV) and of the three vessels and trachea (3VT) view, using color and/or directional power Doppler. All examinations were then reviewed offline and scored for quality by a qualified expert. Sixty observers performed a total of 597 first-trimester ultrasound examinations, each performing an average of 10 (range, 1-26) procedures. Examinations were conducted transabdominally (79%; 472/597), transvaginally (3%; 17/597) or both (18%; 108/597). In 8% (45/597) of cases, the fetal back was anterior, in 18% (108/597) it was on the left side, in 63% (377/597) it was posterior and in 11% (67/597) it was on the right side. It became clear during scoring by the expert that, unlike the Herman quality score for nuchal translucency measurement, it was difficult to assess the quality of these images without taking into account normality of the heart itself. Analysis of scores showed that the 4CV was obtained successfully and was deemed normal in 86% (512/597) of the patients, in 7% (41/597) it was deemed technically infeasible and in 7% (44/597) it was deemed feasible but atypical, which may have been due to the presence of an abnormality or to poor quality of the image. The 3VT view was obtained successfully and was normal in 79% (472/597) of the patients, in 13

Sonographer practitioner development involves the expansion and extension of the sonographer role to include reporting on ultrasound examinations. Australian sonographers have not seen the same degree of role extension and expansion as their counterparts in the United Kingdom, despite increasing levels of discussion regarding sonographer practitioner development. The aim of this study was to determine if Australian sonographers want to extend their professional role and what they consider are the important issues associated with role extension. This paper reports on qualitative data derived from a survey of Australian sonographers and investigates if Australian sonographers are interested in extending and expanding their professional role and responsibilities and, if they do, what might be necessary or desirable from a professional point of view for this change to occur. A survey was mailed to all members of the Australian Sonographers Association (ASA) in October 2006. The 31-item survey included 28 closed-ended and 3 opened-ended items to provide both quantitative and qualitative data. The quantitative data will be reported separately. Qualitative data was derived from responses to the opened-ended questions, which asked respondents to elaborate on their attitudes and feelings about role extension and development. Analysis used Nvivo7 software to aid in uncovering common themes from the qualitative data. The analysis focused on the reported incentives or motivations for becoming a sonographer practitioner as well as disincentives or perceived hurdles that would discourage respondents from becoming sonographer practitioners. The three most reported incentives or motivations for becoming a sonographer practitioner were professional recognition, remuneration and increased knowledge. The three most commonly reported disincentives or perceived hurdles that would discourage respondents from becoming sonographer practitioners were legal issues, insurance and further

This study aimed to assess the sonographic characteristics and interval changes of subacute thyroiditis using follow-up sonography. From January 2008 to December 2014, 85 patients with clinically suspected subacute thyroiditis underwent sonographic examinations by a single radiologist. Subacute thyroiditis was confirmed on the basis of the clinical, sonographic, and cytohistopathologic findings. On the initial and follow-up sonograms, the individual sonographic findings and interval changes were retrospectively investigated by the same radiologist. According to the sonographic configuration, subacute thyroiditis lesions were categorized as nodular or non-nodular. The interval changes in the lesions were classified as follows: "disappeared," "decreased," "increased," "eventually smaller," "eventually larger," or "no interval change." Subacute thyroiditis was confirmed in 64 of the 85 patients. In these 64 patients, nodular (n = 39) and non-nodular (n = 35) lesions were found; 10 patients had both nodular and non-nodular lesions. Of the 64 patients, 41 underwent sonographic follow-up. In both nodular and non-nodular lesions, the common interval changes included disappeared, decreased, and eventually smaller patterns. Although the increased pattern was found only in 4 nodular lesions, there was no significant difference in the interval changes between nodular and non-nodular lesions. On follow-up sonography, a new lesion was detected in 6 patients. The prevalence rate of nodular subacute thyroiditis lesions on sonography was high, and the interval changes in the lesions were variable.

Architectural distortion is a suspicious abnormality for the diagnosis of breast cancer. The aim of this study was to investigate the clinical significance of sonographic ally detected architectural distortion. From January 2006 to June 2008, 20 patients were identified who had sonographic ally detected architectural distortions without a history of trauma or surgery and abnormal mammographic findings related to an architectural distortion. All of the lesions were pathologically verified. We evaluated the clinical and pathological findings and then assessed the clinical significance of the sonographic ally detected architectural distortions. Based on the clinical findings, one (5%) of the 20 patients had a palpable lump and the remaining 19 patients had no symptoms. No patient had a family history of breast cancer. Based on the pathological findings, three (15%) patients had malignancies. The malignant lesions included invasive ductal carcinomas (n = 2) and ductal carcinoma in situ (n = 1). Four (20%) patients had high-risk lesions: atypical ductal hyperplasia (n = 3) and lobular carcinoma in situ (n = 1). The remaining 13 (65%) patients had benign lesions, however, seven (35%) out of 13 patients had mild-risk lesions (three intraductal papillomas, three moderate or florid epithelial hyperplasia and one sclerosing adenosis). Of the sonographic ally detected architectural distortions, 35% were breast cancers or high-risk lesions and 35% were mild-risk lesions. Thus, a biopsy might be needed for an architectural distortion without an associated mass as depicted on breast ultrasound, even though the mammographic findings are normal

The purpose of this study was to quantify spontaneous first trimester miscarriage rates per woman among parous women. A vast amount of data has accumulated regarding miscarriage rates per recognized pregnancy as well as about recurrent miscarriage. This is the second study of miscarriage rates per woman in a parous population and the first study of recurrent and non-recurrent, spontaneous first trimester miscarriage rates per woman in a large parous population. Extraction of the following variables from all delivery room admissions from both Hadassah Medical Centers in Jerusalem Israel, 2004-2014: # of first trimester spontaneous miscarriages, # live births; # living children; age on admission, pre-pregnancy height and weight, any smoking this pregnancy, any alcohol or drug abuse this pregnancy, blood type, history of ectopic pregnancy, history of cesarean surgery (CS) and use of any fertility treatment(s). Among 53,479 different women admitted to labor and delivery ward, 43% of women reported having had 1 or more first trimester spontaneous miscarriages; 27% reported having had one, 10% two, 4% three, 1.3% four, 0.6% five and 0.05% reported having 6-16 spontaneous first trimester miscarriages. 18.5% had one or more first trimester miscarriages before their first live birth. Eighty-one percent of women with 11 or more living children experienced one or more first trimester miscarriages. First trimester miscarriage rates rose with increasing age, increasing parity, after previous ectopic pregnancy, after previous cesarean surgery, with any smoking during pregnancy and pre-pregnancy BMI ≥30. Miscarriages are common among parous women; 43% of parous women report having experienced one or more first trimester spontaneous miscarriages, rising to 81% among women with 11 or more living children. One in every 17 parous women have three or more miscarriages. Depending on her health, nutrition and lifestyle choices, even a 39 year old parous woman with a history of 3 or

The significance of sonographic findings 1 week or less after appendectomy is difficult to evaluate without knowing the inconsequential abnormalities that may occur in these patients. Accordingly, we performed postoperative sonography on patients who had a normal course after appendectomy to determine the findings that can be considered normal within 1 week after surgery. Forty-four patients who had an appendectomy for acute appendicitis and who had normal findings at clinical follow-up 5 days and 6 months later were included in the study. In all patients, sonograms were obtained on the fifth postoperative day and interpreted by a radiologist who did not know the surgical findings. Ten fluid collections (23%) were found in the pericecal area, ranging in size from 10 x 10 mm to 40 x 20 mm. The collections were hypoechoic or anechoic, crescent-shaped, and immobile. Fluid collections were more common in cases of suppurative appendixes (6/20, 30%) than in cases of inflamed appendixes (4/19, 21%) and in retrocecal appendixes (3/9, 33%) than in normally located appendixes (7/34, 21%). However, the differences were not statistically significant (p > .05). Inconsequential fluid collections are detected with considerable frequency on postoperative sonograms 5 days after an appendectomy. Consequently, not every fluid collection should be considered an abscess.

Concern has been expressed about potential harm to women's mental health in association with having an induced abortion, but it remains unclear whether induced abortion is associated with an increased risk of subsequent psychiatric problems. We conducted a population-based cohort study that involved linking information from the Danish Civil Registration system to the Danish Psychiatric Central Register and the Danish National Register of Patients. The information consisted of data for girls and women with no record of mental disorders during the 1995-2007 period who had a first-trimester induced abortion or a first childbirth during that period. We estimated the rates of first-time psychiatric contact (an inpatient admission or outpatient visit) for any type of mental disorder within the 12 months after the abortion or childbirth as compared with the 9-month period preceding the event. The incidence rates of first psychiatric contact per 1000 person-years among girls and women who had a first abortion were 14.6 (95% confidence interval [CI], 13.7 to 15.6) before abortion and 15.2 (95% CI, 14.4 to 16.1) after abortion. The corresponding rates among girls and women who had a first childbirth were 3.9 (95% CI, 3.7 to 4.2) before delivery and 6.7 (95% CI, 6.4 to 7.0) post partum. The relative risk of a psychiatric contact did not differ significantly after abortion as compared with before abortion (P = 0.19) but did increase after childbirth as compared with before childbirth (P abortion does not support the hypothesis that there is an increased risk of mental disorders after a first-trimester induced abortion.

Unilateral breast edema has many causes, though among these, congestive heart failure is rare. We report mammographic and sonographic findings of unilateral breast edema due to congestive heart failure. Mammography showed diffuse increase density and skin thickening but no evidence of mass or calcification. Ultrasonography showed skin thickening and increased echogenicity in the subcutaneous fat layer, while in the dermal layer, with tubular and reticular anechoic structures suggestive of dilated lymphatics were seen. After treatment of the heart failure, resolution of the abnormalities seen on mammogram established that these were secondary findings.

Full Text Available To the best of our knowledge this is the first case report describing exposure to varenicline, an α4β2 nicotinic acetylcholine partial receptor agonist used for smoking cessation therapy in pregnancy. A 29-year-old multiparous woman with an unplanned pregnancy has used varenicline 2 mg/day unintentionally yet regularly 4 weeks from her last menstrual period. Fetal ultrasound performed at each trimester, detailed anomaly scan, and fetal echocardiography which were performed at the 22nd gestational week showed normal fetal growth with no malformations. The patient delivered a healthy baby at the 38th week of gestation with normal Apgar score and physical examination findings. Age-appropriate physical and neurological development of the child has been observed for 6 months. Although it is not possible to draw definitive conclusions, this case report may contribute to the current available limited data regarding the safety of varenicline use in pregnancy.

Mammographic and sonographic findings of steatocystoma multiplex presenting as breast lumps.

Wan, John Mun Chin; Wong, Jill Su Lin; Tee, Shang-Ian

2012-12-01

Steatocystoma multiplex (SM) is an uncommon cutaneous disorder characterised by multiple intradermal cysts distributed over the trunk and proximal extremities. This condition affects both genders and is often inherited as an autosomal dominant trait, although sporadic cases have been described. This report describes the mammographic and sonographic features of the cysts, which presented as breast lumps, for evaluation. The cysts appeared as numerous well-circumscribed, radiolucent nodules with thin radiodense rims on mammography. On sonography, the cysts could be hypoechoic, isoechoic or demonstrate mixed echoes containing debris-fluid levels, depending on the amount of clear oily liquid and keratinous material. SM can be diagnosed based on a clinical setting of multiple asymptomatic small intradermal nodules over the trunk and proximal extremities, positive family history and imaging findings.

The challenges of the first-trimester examination of the fetal heart may in part be overcome by technical advances in three-dimensional (3D) ultrasound techniques. Our aim was to standardize the first-trimester 3D imaging approach to the cardiac examination to provide the most consistent and accurate display of anatomy. Low-risk women with normal findings on first-trimester screening at 11 to 13 + 6 weeks had cardiac ultrasound using the following sequence: (1) identification of the four-chamber view; (2) four-dimensional (4D) volume acquisition with spatiotemporal image correlation (STIC) and color Doppler imaging (angle = 20 degrees, sweep 10 s); (3) offline, tomographic ultrasound imaging (TUI) analysis with standardized starting plane (four-chamber view), slice number and thickness; (4) assessment of fetal cardiac anatomy (four-chamber view, cardiac axis, size and symmetry, atrioventricular valves, great arteries and descending aorta) with and without color Doppler. 107 consecutive women (age, 16-42 years, body mass index 17.2-50.2 kg/m(2)) were studied. A minimum of three 3D volumes were obtained for each patient, transabdominally in 91.6%. Fetal motion artifact required acquisition of more than three volumes in 20%. The median time for TUI offline analysis was 100 (range, 60-240) s. Individual anatomic landmarks were identified in 89.7-99.1%. Visualization of all structures in one panel was observed in 91 patients (85%). Starting from a simple two-dimensional cardiac landmark-the four-chamber view-the standardized STIC-TUI technique enables detailed segmental cardiac evaluation of the normal fetal heart in the first trimester.

We analyzed the sonograms of 6 cases with uterine synechiae in pregnancy. The diagnosis was based on the clinical and sonographic findings. Previous curret age during the artificial abortion and/or after the spontaneous abortion had been done in 5 cases (83.3%). In all cases, uterine synechia in pregnancy was recognized asintra-amniotic sheet containing hypoechoic central zone and an hyperechoic outer layers. Y-shaped splitting of thehyperechoic outer layers was seen against the uterine wall. The placenta extended along the sheet in 4 cases. Uterine synechiae in pregnancy should be distinguished from amniotic band syndrome by the characteristic snographic findings, and unwarranted abortion of normal fetus should be avoided

Transvaginal(TV) sonography uses high-frequency transducer and allows access to the uterus and adnexa, provides better resolution and more accurate diagnosis of ectopic pregnancy. To determine the value and the utility of TV sonography for a suspected ectopic pregnancy, we studied 56 women during 4 months from January to April 1989. Of 56 patients 46 had an surgically confirmed ectopic pregnancy, 5 had not an ectopic pregnancy and 5 had not follow up. TV sonography provides definite sonographic diagnosis of ectopic pregnancy including an extrauterine gestational sac 34 cases(74%), extrauterine embryo 9 caes(19.7%), hematosalpinx 10 cases(21.7%). Overall adnexal mass was detected in 38 cases(82.6%) at initial TV sonography and in 44 cases(95.6%) at follow up TV sonography. Additional findings were uterine decidual reaction 19 cases(41.3%), pseudo G-sac 4 cases(8.7%), cul-de-sac fluid 42 cases(91.2%). Follow-up TV sonography showed newly developed or growing adnexal mass in 8 among 9 cases. False positive 5 cases were two ovarian cysts, one incomplete abortion, two parametrial thickening due to previous ectopic pregnancy and salpingectomy. TV sonography may improve the govality of patient management by early diagnosis and early surgical treatment, so may preserve fertility. In conclusion, we may suggest that TV sonography is an integral part of diagnostic modality in suspected ectopic pregnancy.

2017-04-01

Early diagnosis of breast vasculitis (BV) is difficult because this condition is rare and occasionally mimics breast cancer clinically or radiologically. It may present as systemic disease or as an isolated lesion in the breast, without systemic evidence. When vasculitis appears in the breast, it also might manifest as a tumor-like lesion, and in previous cases, tissue acquisition was needed for confirmation of the diagnosis because of BV's resemblance to inflammatory breast cancer. We report a case of isolated BV that was suspected of being inflammatory breast cancer clinically, but manifested as bilateral breast edema on mammography. In this case, sonographic findings included not only nonspecific edema findings that might be seen in other cases, but also suggestive findings of hypoechoic circumferential arterial wall thickening with perivascular fat infiltrations that are similar to the halo sign in large arteries but have not been reported in the breast. These are helpful for presumptive diagnosis of BV using ultrasound.

To evaluate whether maternal serum α-fetoprotein (MSAFP) improves the detection rate for open neural tube defects (ONTDs) and ventral wall defects (VWD) in patients undergoing first-trimester and early second-trimester fetal anatomical survey. A cohort of women undergoing screening between 2005 and 2012 was identified. All patients were offered an ultrasound at between 11 weeks and 13 weeks and 6 days of gestational age for nuchal translucency/fetal anatomy followed by an early second-trimester ultrasound at between 15 weeks and 17 weeks and 6 days of gestational age for fetal anatomy and MSAFP screening. All cases of ONTD and VWD were identified via query of billing and reporting software. Sensitivity and specificity for detection of ONTD/VWD were calculated, and groups were compared using the Fisher exact test, with p met the criteria for inclusion. Overall, 15 cases of ONTD and 17 cases of VWD were identified; 100% of cases were diagnosed by ultrasound prior to 18 weeks' gestation; none were diagnosed via MSAFP screening (p < 0.001). First-trimester and early second-trimester ultrasound had 100% sensitivity and 100% specificity for diagnosing ONTD/VWD. Ultrasound for fetal anatomy during the first and early second trimester detected 100% of ONTD/VWD in our population. MSAFP is not useful as a screening tool for ONTD and VWD in the setting of this ultrasound screening protocol. © 2014 S. Karger AG, Basel.

We reviewed the sonographic features of Morel-Lavalle'e lesions by correlating the US image findings with a lesion's age. We obtained the sonography reports of 20 Morel-Lavalle'e lesions of the hip and extremities from 18 patients with a history of trauma. The US images were reviewed to characterize the echogenicity, shape, homogeneity, margins, location and size of the lesions. The results were correlated with the age of the lesions and the clinical histories. All the Morel-Lavalle'e lesions were hypoechoic or anechoic fluid collections located between the subcutaneous fat and the underlying fascia. Regarding the shape of the fluid collections, the lobular shaped lesions were all less than 21 days for the lesion's age, and the flat fluid collections were all greater than 1 month of age. Regarding the homogeneity, the heterogeneous fluid collections were all less than 25 days of age, and the homogeneous fluid collections were all greater than 1 month of age. A Morel-Lavalle'e lesion is seen as a posttraumatic fluid collection in the potential space between the subcutaneous fat and the underlying fascia on an ultrasound examination. Acute Morel-Lavalle'e lesions tended to be heterogeneous and lobular, and they became more homogeneous and flat in shape as the lesions evolved. Awareness of these imaging findings will help us to properly diagnose Morel- Lavalle'e lesions

To analyze sonographic findings suggesting central lymph node metastasis of papillary thyroid carcinoma and to evaluate the influence of associated chronic lymphocytic thyroiditis on the diagnostic performance of sonography for predicting central lymph node metastasis. A total of 124 patients (101 female and 23 male; mean age, 47.5 years; range, 21-74 years) underwent sonographically guided fine-needle aspiration in central lymph nodes from January 2008 to July 2011. Sonographic features of size, shape, margin, thickening of the cortex, cortical echogenicity, presence of a hilum, cystic changes, calcification, and vascularity of enlarged lymph nodes were analyzed before fine-needle aspiration and classified into 2 categories (probably benign and suspicious). Sonographic findings were correlated with the pathologic diagnosis and associated chronic lymphocytic thyroiditis. Receiver operating characteristic curve analysis was performed to assess the diagnostic performance of sonography for predicting central lymph node metastasis according to the associated thyroiditis. Fifty-one lymph nodes (39.5%) were malignant, and 73 (60.5%) were benign. On univariate analysis, size, shape, margin, cortical thickening, cortical echogenicity, cystic changes, calcification, and vascularity were significantly different between the benign and metastatic nodes (P thyroiditis-positive patients and 0.971 (95% CI, 0.938-1.000) in negative patients. Eccentric cortical thickening and cortical hyperechogenicity were the sonographic findings predictive of central lymph node metastasis from papillary thyroid carcinoma. The diagnostic performance of sonography for predicting metastasis was superior in chronic lymphocytic thyroiditis-negative patients than in positive patients.

The purpose of this study was to estimate the rate of incomplete fetal anatomic surveys during a second-trimester scan due to an unfavorable fetal position in a nonobese population. All pregnant women who came to the Altamedica Fetal-Maternal Medical Center, a specialized center for prenatal diagnosis, for a routine second-trimester scan between January 2012 and April 2013 were retrospectively included in the analysis. Patients with a body mass index higher than 30.0 kg/m(2) or anterior fibroids larger than 5 cm were not included in the study. Of 4000 pregnant women admitted for a second-trimester scan, 169 (4.2%) came back within 2 weeks to complete the examination because of an unfavorable fetal position. In particular, 104 (2.6%) needed visualization of only 1 view, and 65 (1.6%) needed more than 1 view. The most difficult organ to visualize was the corpus callosum, in 73 cases (1.8%); the face was not visualized in 69 cases (1.7%); the cerebellar vermis was not seen in 47 fetuses (1.1%); and the heart could not be completely examined in 40 fetuses (1.0%). Of the 4000 women, 169 (4.2%) had a nonexhaustive scan; 149 (3.7%) needed a second scan to complete the second-trimester survey; 14 (0.35%) needed a third scan; and 2 (0.05%) remained with a not completely exhaustive scan. There is always a small percentage of incomplete fetal anatomic surveys during a second-trimester scan, which cannot be modified by the sonographer's skill or by technical sonographic innovations. © 2015 by the American Institute of Ultrasound in Medicine.

Full Text Available BACKGROUND Breast diseases are common in females. In developing countries like India, females are unaware of breast pathologies hence they are detected usually in advanced stages. We have studied 100 patients of palpable breast masses presenting to our department and evaluate the role of combined mammographic and sonographic imaging in patients with palpable abnormalities of the breast, which help in decision making by clinician as to lesion go for biopsy or follow up. MATERIALS AND METHODS The study was conducted at Department of Radiodiagnosis J. L.N. Medical College & Associated Groups of Hospitals, Ajmer. We included women equal to or more than 30 years referred to this centre with palpable abnormalities of breast during a period from March 2015 to August 2016. All these women underwent a combined mammographic and sonographic evaluation of breast. RESULTS 50 (50% of the 100 palpable abnormalities had benign assessment, 30 (60% of the benign lesions were visible both on mammography and sonography; 18 (36% of the 50 benign lesions were mammographically occult and identified at sonographic evaluation. 2 lesion was sonographically occult (4% and visualized on mammography. In 14 (14% of the 100 cases, imaging evaluation resulted in a suspicious assessment and all these lesions underwent biopsy and 4 were diagnosed as having malignancy. 36(36% of the 100 palpable abnormalities had negative imaging assessment finding: of these 14 patients underwent biopsy and all had benign findings. The sensitivity and negative predictive value for combined mammographic and sonographic assessment were 100%; the specificity was 78.26%. CONCLUSION Combined use of mammography and sonography plays an important role in the management of palpable breast lesions. It characterizes the palpable mass lesion, avoids unnecessary interventions in which imaging findings are unequivocally benign. Negative findings on combined mammographic and sonographic imaging have very high

Full Text Available Illicit drug abuse is a major area of interest for clinicians, as well as for public health and social authorities, but one of the major concerns is the illicit drug abuse during the periconceptional period and throughout pregnancy, because of its potential effects on the embryo and fetus. In this study we investigated the prevalence of illicit drug abuse in the first trimester of pregnancy in women who referred to Iran, Tehran and Shahid Beheshti universities of medical sciences, for prenatal care."nMaterials and Methods: In this descriptive cross sectional study, a non-randomized sample of 2000 pregnant women that were in their second and third trimester of their pregnancy, were interviewed about drug abuse in their first trimester. Collected data were analyzed by SPSS software."nResults: The prevalence of illicit drug abuse in the first trimester was 2.5% which the majority of these drugs were in group B. The prevalence of drug abuse was 0.9% and alcohol usage and alcohol abuse was 0.2%, cigarette smoking was the most common drug abusing phenomena. Variables such as husband education, infertility and satisfaction with pregnancy have significant relation with drug abuse."nConclusion: The results of this study support the need for continued education and this education must end in by itself to make dramatic changes in behavior. So results of this study showed that, improving education and knowledge of mothers and consultation with them in regard to risks and complications of drug abuse during pregnancy, would make dramatic changes in their behavior."n"n"n"n"n"n"n"n

Full Text Available To evaluate in a national standardised setting whether the performance of ultrasound dating during the first rather than the second trimester of pregnancy had consequences regarding the definition of pre- and post-term birth rates.A cohort study of 8,551 singleton pregnancies with spontaneous delivery was performed from 2006 to 2012 at Copenhagen University Hospital, Holbæk, Denmark. We determined the duration of pregnancy calculated by last menstrual period, crown rump length (CRL, biparietal diameter (1st trimester, BPD (2nd trimester, and head circumference and compared mean and median durations, the mean differences, the systematic discrepancies, and the percentages of pre-term and post-term pregnancies in relation to each method. The primary outcomes were post-term and pre-term birth rates defined by different dating methods.The change from use of second to first trimester measurements for dating was associated with a significant increase in the rate of post-term deliveries from 2.1-2.9% and a significant decrease in the rate of pre-term deliveries from 5.4-4.6% caused by systematic discrepancies. Thereby 25.1% would pass 41 weeks when GA is defined by CRL and 17.3% when BPD (2nd trimester is used. Calibration for these discrepancies resulted in a lower post-term birth rate, from 3.1-1.4%, when first compared to second trimester dating was used.Systematic discrepancies were identified when biometric formulas were used to determine duration of pregnancy. This should be corrected in clinical practice to avoid an overestimation of post-term birth and unnecessary inductions when first trimester formulas are used.

To investigate the association between chemerin level in the first trimester of pregnancy and the risk of gestational diabetes mellitus. The blood samples of 212 women at 8-12 weeks of gestation were collected. After screening for gestational diabetes mellitus (GDM), 19 women with GDM and 20 women randomly selected from 144 women with normal glucose tolerance (NGT) were included in the study. Blood samples were collected from these women. Triglycerides, glucose, total cholesterol, and HDL cholesterol, LDL cholesterol, insulin and chemerin were measured. Gestational weight gain and body mass index was assessed. Serum levels of chemerin were significantly elevated during late gestation, and the risk of GDM was positively associated with maternal serum chemerin in the first trimester. Serum chemerin level during the first trimester of pregnancy has the potential to predict risk of GDM.

The authors retrospectively analysed the ultrasonographic findings of 43 cases of surgically confirmed hypertrophic pyloric stenosis and their postoperative findings of sonograms taken at 1 month(n=40) or 3 month(n=5) after pyloromyotomy. In preoperative study, the thickened pyloric muscle was isoechoic or slight hypoechoic relative to liver on the midline longitudinal view and appeared as a 'nonuniform acoustic ring' on the transverse view. The results of measurement in the all cases with hypertrophic pyloric stenosis were the pyloric muscle thickness ≥ 3.8 mm, the pyloric diameter ≥ 14 mm, the pyloric channel length ≥ 16 mm, the pyloric muscle volume ≥ 2.21 cm 3 and the pyloric muscle index ≥ 0.57, respectively. It usually required 1 month after operation for the hypertrophied muscle to resolve in 36 of 41 patients. The normalized pyloric muscle appeared more hypoechoic than that of adjacent parenchyma, and the nonuniform echogenicity of the pyloric muscle disappeared. Five patients whose hypertrophied muscle did not return to normal range on 1 month's follow-up sonogram were follow-up 3 months later again, and we have ascertained their resolution in all of them. In conclusion, the pre-operative sonographic findings of infantile hypertrophic pyloric stenosis were different quantitatively and qualitatively from of those of post-operative follow-up ultrasound exam. High-resolution real time sonography is a safe and accurate method for the diagnosis of hypertrophic pyloric stenosis and useful in postpyloromyotomy follow-up

Craniosynostosis syndromes are uncommonly encountered in the prenatal period. Identification is challenging but important for family counseling and perinatal management. This series examines prenatal findings in craniosynostosis syndromes, comparing the complementary roles of US and MRI and emphasizing clues easily missed in the second trimester. Six prenatal cases evaluated from 2002 through 2011 were retrospectively reviewed. Referral history, gestational age, and sonographic and MRI findings were reviewed by three pediatric radiologists. Abnormalities of the calvarium, hands, feet, face, airway and central nervous system were compared between modalities. The diagnosis was Apert syndrome in three, Pfeiffer syndrome in two and Carpenter syndrome in one. The gestational age at evaluation ranged from 21 to 33 weeks. All six were evaluated by MRI and US, with two undergoing repeat evaluation in the third trimester, yielding a total of eight MRIs and US exams. The referral history suggested cloverleaf skull in two cases but did not suggest craniosynostosis syndrome in any case. In four, the referral suggested central nervous system (CNS) findings that were not confirmed by MRI; additional CNS findings were discovered in the remaining two. In four cases, developing turricephaly resulted in a characteristic ''lampshade'' contour of the fetal head. Hypertelorism and proptosis were present in five, with proptosis better appreciated by MRI. Digit abnormalities were present in all, seen equally well by MRI and US. Lung abnormalities in the second trimester in one fetus resolved by the third trimester. Prenatal diagnosis of craniosynostosis syndromes is difficult prior to the third trimester. MRI and US have complementary roles in evaluation of these patients. (orig.)

Since 2007 the second-trimester fetal anomaly scan is offered to all pregnant women as part of the national prenatal screening program in the Netherlands. Dutch population-based screening programs generally have a well-described system to achieve quality assurance. Because of the absence of a uniform system to monitor the actual performance of the fetal anomaly scan in 2012, we developed a standardized image-scoring method. The aim of this study was to evaluate the scanning performance of all sonographers in the southwestern region of the Netherlands using this image-scoring method. Each sonographer was requested to set up a digital portfolio. A portfolio consists of five logbooks from five different pregnant women, each containing 25 fetal anatomical structures and six biometric measures of randomly selected fetal anomaly scans. During the study period, 425 logbooks of 85 sonographers were assessed as part of the audit process. Seventy-three out of 85 sonographers (86%) met the criteria in the primary audit, and 12 sonographers required individual hands-on training. A successful assessment was achieved for 11 sonographers in the re-audit and one sonographer ceased her contract. Moreover, 2.1% of the required images were not digitally stored and therefore could not be reviewed. Quality assessment using the image-scoring method demonstrated that most of the sonographers met the expectations of the audit process, but those who had subpar performance met the expectations after retraining. © 2017 by the American Institute of Ultrasound in Medicine.

Multiple factors, including proteinuria, antiphospholipid syndrome, thrombocytopenia and hypertension, are predictive of pregnancy loss in systemic lupus erythematosus (SLE). In the PROMISSE study of predictors of pregnancy loss, only a battery of lupus anticoagulant tests was predictive of a composite of adverse pregnancy outcomes. We examined the predictive value of one baseline lupus anticoagulant test (dilute Russell viper venom time) with pregnancy loss in women with SLE. From the Hopkins Lupus Cohort, there were 202 pregnancies from 175 different women after excluding twin pregnancies and pregnancies for which we did not have a first trimester assessment of lupus anticoagulant. We determined the percentage of women who had a pregnancy loss in groups defined by potential risk factors. The lupus anticoagulant was determined by dilute Russell viper venom time with appropriate mixing and confirmatory testing. Generalised estimating equations were used to calculate p values, accounting for repeated pregnancies in the same woman. The age at pregnancy was 40 (3%). 55% were Caucasian and 34% African-American. Among those with lupus anticoagulant during the first trimester, 6/16 (38%) experienced a pregnancy loss compared with only 16/186 (9%) of other pregnancies (p=0.003). In addition, those with low complement or higher disease activity had a higher rate of pregnancy loss than those without (p=0.049 and 0.005, respectively). In contrast, there was no association between elevated anticardiolipin in the first trimester and pregnancy loss. The strongest predictor of pregnancy loss in SLE in the first trimester is the lupus anticoagulant. In addition, moderate disease activity by the physician global assessment and low complement measured in the first trimester were predictive of pregnancy loss. These data suggest that treatment of the lupus anticoagulant could be considered, even in the absence of history of pregnancy loss.

Tenosynovitis of the extremities is not uncommon but its diagnosis is not easy owing to its non-specific clinical manifestation. Thus it was beyond the field of imaging diagnosis so far. Recently the development of high resolution ultrasonogram has aided preoperative imaging diagnosis of tenosynovitis. The authors performed a retrospective reviewed of 27 patients who had ultrasonography due to tendon pathology(including 18 tenosynovitis) by observing sonographic findings and evaluation the diagnosis value of each finding. The overall diagnostic accuracy was 81.1% and common sonographic findings were focal swelling of the tendon, well-defined margin of the lesion, preserved fibrillar pattern, echo change of the lesion site and fluid collection. Above all, fluid collection. was the only statistically significant criterion for diagnosis of tenosynovitis(p<0.05). But its sensitivity was as low as 50%. In conclusion the ultrasonography is useful in diagnosis of tenosynovitis and fluid collection is of diagnostic value, but the differentiation between nodular tenosynovitis without fluid collection and other benign tumor is still beyond the scope of ultrasonographic diagnosis.

High level of oxidative stress (OS) during the first weeks of pregnancy is related to many serious pregnancy complications. Previous studies showed that body fluctuating asymmetry (FA) is related to OS level in men, suggesting that FA is a marker of oxidative balance in an individual. The aim of this study was to analyze if body FA was related to the level of biomarkers of OS in the first trimester of pregnancy. The sample included 34 women in the first trimester of pregnancy, not smoking, and not exposed to toxins in their work environment. The composite FA and levels of two biomarkers of OS, 8-iso-ProstaglandinF2α (an indicator of oxidative damage to lipids) and 8-OH-dG (an indicator of oxidative damage to DNA) were measured. Factors that may affect the level of OS (vitamin supplementation, age, smoking, alcohol drinking, physical activity, and health condition) were controlled. The levels of OS markers in the first trimester of pregnancy correlated positively with women's FA (r = 0.52, P = 0.002 for 8-OH-dG; r = 0.50; P = 0.003 for 8-iso-PGF2α level) and positively with body height (r = 0.37, P = 0.03 for 8-OH-dG level). The level of OS is likely to be a substantial and important fitness trait, and FA may convey information on the level of OS in women. The result confirms that FA is an indicator of biological condition, as suggested by an evolutionary approach to morphological human traits perceived as attractive. © 2015 Wiley Periodicals, Inc.

1987-01-01

Primary pathologic processes involving the renal pyramids such as papillary necrosis, drug-induced necrosis or calcinosis, cysts, neoplasms, and medullary nephrocalcinosis are rare. Thirty-four patients with primary renal pyramid diseases underwent US evaluation for altered morphology; a 5-MHz transducer was used. In 20 patients site-specific changes in the pyramid (e.g., papillary necrosis at the apex, small cysts at the base in medullary cystic disease, tubular calcification in MSK, corticomedullary hyperechogenicity in oxalosis) were noted on US. Sonographic delineation of the site and pattern of pathologic changes in the renal pyramid may help to identify specific diseases

Full Text Available The Arnold-Chiari malformation is a congenital abnormality of CNS, characterized by downwarddisplacement the parts of the cerebellum, fourth ventricle, pons and medulla oblongata into thespinal canal. This malformation is one of causative factor of death in neonates and infants. Athorough understanding of the direct and indirect sonographic findings is necessary for diagnosis ofChiari II malformation in the developing fetus.In this case report, we present a Chiari malformation II detected at 23 weeks of gestation by routinelysonographic screening. The Role of prenatal sonography in recognition of the malformation andprognostic value of these features are discussed.

Technical standards and guidelines: prenatal screening for Down syndrome that includes first-trimester biochemistry and/or ultrasound measurements.

2009-09-01

This statement is intended to augment the current general ACMG Standards and Guidelines for Clinical Genetics Laboratories and to address guidelines specific to first-trimester screening for Down syndrome. The aim is to provide the laboratory the necessary information to ensure accurate and reliable Down syndrome screening results given a screening protocol (e.g., combined first trimester and integrated testing). Information about various test combinations and their expected performance are provided, but other issues such as availability of reagents, patient interest in early test results, access to open neural tube defect screening, and availability of chorionic villus sampling are all contextual factors in deciding which screening protocol(s) will be selected by individual health care providers. Individual laboratories are responsible for meeting the quality assurance standards described by the Clinical Laboratory Improvement Act, the College of American Pathologists, and other regulatory agencies, with respect to appropriate sample documentation, assay validation, general proficiency, and quality control measures. These guidelines address first-trimester screening that includes ultrasound measurement and interpretation of nuchal translucency thickness and protocols that combine markers from both the first and second trimesters. Laboratories can use their professional judgment to make modification or additions.

Circumscribe breast cancer is a well demarcated mass with or without a lobulated border simulating a benign tumor like fibroadenoma on mammography or breast US and is reported as approximate 10% of the incidence among primary breast carcinoma(1.2). Pathologically medullary, colloid, papillary, intraductal and rarely invasive ductal carcinomas are included in this group which show the less intense desmoplastic reaction than the scirrhous type cancer, resulting in the most favorable prognosis of all carcinoma of the breast. Among 214 primary breast carcinoma during the past 8 years, we experienced 6 case of pathologically proven circumscribed breast cancer(2 cases of medullary carcinoma, 1 of colloid carcinoma, 1 of intracystic papillary carcinoma, 2 of comedo type intraductal carcinoma). Clinically 2 cases showed bloody nipple discharge from one hole of a unilateral nipple orifice. Mammography showed a well circumscribed nodule with or without partial lobular contour and no pathologic calcification. Breast sonographic findings were a well defined heterogeneous hypoechoic nodule with weak posterior acoustic enhancement. Characteristically a thin dilated lactiferous duct between the mass and the nipple on US could be detected in 2 cases which clinically was accompanied by bloody nipple discharge. Although the mammographic criteria is promising as benign tumor, the possibility of circumscribed as benign tumor, the possibility of circumscribed breast carcinoma must be considered in heterogeneous hypoechoic nodule with weak posterior acoustic enhancement in US, especially in the presence of a dilated lactiferous duct between the mass and the nipple with bloody nipple discharge.

We examined the association between maternal characteristics, routinely collected first- and second-trimester biomarkers and the risk of having an infant with a critical congenital heart defect (CCHD). Included were women who participated in the California Prenatal Screening Program who had nuchal translucency (NT) measurement and first- and second-trimester serum screening. All pregnancies ended in a live birth of an infant without aneuploidy or a neural tube defect. Poisson regression analyses were used to estimate the relative risk and 95% confidence interval of a CCHD by maternal characteristics, first- and second-trimester serum biomarkers or NT measurements. The sample included 118,194 mother-infant pairs; 284 infants had a CCHD. Women with preexisting diabetes were three-times as likely to have an infant with a CCHD. After adjusting for preexisting diabetes, women with first-trimester human chorionic gonatotropin (hCG) measurement <10th centile were 1.6-times as likely to have an infant with a CCHD (P = 0.011). Women with a NT measurement ≥95th centile were at two- to threefold higher risk of having an infant with a CCHD (P's = 0.004-0.007). Pregnancies with two risk factors for an infant with a CCHD were 5.6-times more likely to have an infant with a CCHD than women with no identified risk factors (P < 0.001). Despite the increased risk, performance testing demonstrated low sensitivity and specificity for screening use of these risk factors. Of the women with an infant with a CCHD, only 21.8% had an identified risk factor. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

Evidence demonstrates that health care professionals are more prone to burnout than other professionals due to the emotionally taxing interactions they have with their patients on a daily basis. The aims of this study were to measure occupational burnout levels among sonographers, radiographers and radiologists and to examine predictors of burnout according to demographic characteristics. A cross-sectional online survey was administered in 2010 to radiographers, sonographers and radiologists who were members of the following professional bodies: Australian Institute of Radiography, Australian Sonographers Association and The Royal Australian and New Zealand College of Radiologists. The Maslach Burnout Inventory was used to measure burnout levels for each profession. Data were analysed using SPSS Ver 20 (IBM, Chicago, IL, USA) statistical software. A total of 613 radiographers, 121 sonographers and 35 radiologists participated in the survey. Radiographers, sonographers and radiologists had a high mean (±SD) burnout score for emotional exhaustion (39.9 ± 8.5, 42.2 ± 8.5 and 44.9 ± 7.1 respectively) and depersonalization (18.9 ± 5.5, 20.3 ± 5.8 and 20.6 ± 5.6) compared to MBI norms. Radiographers also had low personal achievement (30.8 ± 5.5) compared to MBI norms. Radiographers and sonographers who were male, worked >10 hours overtime and spent <10% of their time training students per week had significantly higher depersonalization scores (p < 0.05). Burnout levels among radiographers, sonographers and radiologists are high and likely to vary according to some demographic and work-related factors. Further research is needed to examine ways to alleviate burnout in these professions so that loss of experienced staff due to burnout can be minimized and quality of patient care can be maintained. © 2016 The Royal Australian and New Zealand College of Radiologists.

The aim of this study was to evaluate mammographic and sonographic changes at the surgical site within the first 2 years after IORT as a boost followed by whole-breast radiotherapy (WBRT), compared with a control group treated with WBRT alone. All patients had breast-conserving surgery for early-stage breast cancer. Group A: n = 27, IORT (20 Gy) followed by WBRT (46 Gy). Group B (control group): n = 27, WBRT alone (56-66 Gy). Mammography: fat necrosis in 14 group A versus four group B patients (P < 0.001); parenchymal scarring classified as unorganized at the last follow-up in 16 vs seven cases, respectively (P = 0.03). Ultrasound: overall number of patients with circumscribed findings 27 vs 18 (P < 0.001); particular hematomas/seromas in 26 vs 13 patients (P < 0.001). Synopsis of mammography and ultrasound: overall postoperative changes were significantly higher classified in group A (P = 0.01), but not judged to have a significantly higher impact on interpretation. Additional diagnostic procedures, due to unclear findings at the surgical site, were performed on four patients of both groups. Within the first 2 years after IORT as a boost, therapy-induced changes at the original tumor site are significantly more pronounced compared with a control group. There is no evidence that the interpretation of findings is complicated after IORT. (orig.)

Neonatal mastitis and neonatal breast abscess are uncommon. Although well described in the pediatric and surgical literature, there is a paucity of reports describing their sonographic features. To describe and illustrate the sonographic features of neonatal mastitis and neonatal breast abscess. We reviewed the medical database of a large children's health-care center from 2000 through 2008 for patients presenting in the first 8 weeks of life with mastitis. The findings were correlated with clinical presentation and course, laboratory findings and clinical outcome. Four neonates (three girls and one boy) presented with mastitis. They all had prominent breast buds on the affected side with poorly defined margins, slightly more echogenic focally or diffusely compared to normal with hyperemia on color flow Doppler US. The surrounding subcutaneous tissue was thick and echogenic. Two abscesses presented as avascular areas without color flow on Doppler US, subtly increased through-transmission and surrounding hyperemia. One abscess was of increased echogenicity while the other was anechoic. Neonatal mastitis and breast abscess are unusual diseases that should be appropriately treated with antibiotics and drainage to avoid generalized sepsis, breast hypoplasia, and scarring. US is useful in distinguishing mastitis from breast abscess and guiding treatment options.

2016-11-01

To investigate maternal serum inhibin as a marker of pre-eclampsia (PE) in twins. One hundred forty-three twins and 109 unaffected singleton pregnancies were recruited in the first trimester from the same institution. Blood samples were stored at recruitment and in the second trimester, retrospectively tested for inhibin and values expressed in multiples of the gestation-specific median (MoMs) in singletons, adjusted for maternal weight, as appropriate. The median inhibin level in unaffected twins was 2.04 MoM compared with 1.00 MoM in singletons (P < 0.0001, Wilcoxon Rank Sum Test, one-tailed). Excluding early fetal losses the median in 22 samples from 12 twins with PE was 2.65 MoM compared with 1.99 MoM in 201 samples from 120 unaffected twins (P < 0.02, Wilcoxon Rank Sum Test). This effect was restricted to second trimester samples with medians in cases and controls of 2.86 and 1.91 MoM respectively. Logistic regression of inhibin A together with established PE marker placental growth factor and placental associated plasma protein showed that in the second trimester, it improved screening performance although not reaching statistical significance (P = 0.08). Inhibin A is a potential second trimester marker of PE in twins. It may improve on existing twin screening protocols but more data are required. © 2016 John Wiley & Sons, Ltd. © 2016 John Wiley & Sons, Ltd.

Full Text Available Cerebrovascular accidents (CVA are important causes of neurological clinical signs in dogs. The objective of this work was to describe concurrent diseases and ultrasonographic features in dogs with CVA confirmed through postmortem evaluation. All medical records of transcranial Doppler ultrasonography (TCDUS examinations performed in 512 dogs between 2007 and 2009 were reviewed, searching for history and clinical diagnosis, as well as sonographic and histological results. Forty-two dogs were selected, showing acute onset of clinical signs with no progressive focal cerebral dysfunction and diagnosis of cerebrovascular disease confirmed at necropsy. Concurrent diseases and conditions were: cerebral amyloid microangiopathy (33%, endocrinopathies (31%, coagulopathy (24%, Schnauzer hyperlipemia (7% and unknown (5%. The relation between sonography and histology results indicated 100% sensitivity and 90% specificity for focal lesion detection. A diffuse decrease in echogenicity was related to inflammatory diseases and/or edema with 62% sensitivity. A diffuse increase in echogenicity has 100% sensitivity and was usually related to aging changes. This study showed the occurrence of coexisting diseases with CVA and sonographic features of these conditions in small breed dogs.

Edward E Winger

Full Text Available We investigated the capacity of microRNAs isolated from peripheral blood buffy coat collected late during the first trimester to predict preeclampsia.The cohort study comprised 48 pregnant women with the following pregnancy outcomes: 8 preeclampsia and 40 with normal delivery outcomes. Quantitative rtPCR was performed on a panel of 30 microRNAs from buffy coat samples drawn at a mean of 12.7±0.5 weeks gestation. MicroRNA Risk Scores were calculated and AUC-ROC calculations derived.The AUC-ROC for preeclampsia risk was 0.91 (p<0.0001. When women with normal delivery and high-risk background (those with SLE/APS, chronic hypertension and/or Type 2 Diabetes were compared to women who developed preeclampsia but with a normal risk background (without these mentioned risk factors, preeclampsia was still predicted with an AUC-ROC of 0.92 (p<0.0001.MicroRNA quantification of peripheral immune cell microRNA provides sensitive and specific prediction of preeclampsia in the first trimester of pregnant women. With this study, we extend the range during which disorders of the placental bed may be predicted from early to the end of the first trimester. This study confirms that buffy coat may be used as a sample preparation.

Full Text Available Background: Birth weight has been shown to be influenced by numerous factors including, maternal characteristics such as maternal BMI. In pregnancy, there is increased adipose tissue which can cause to maternal obesity and insulin resistance. There is visfatin expression increase specific to pregnancy. Aim: We planned this study to assess relationships of the first trimester maternal BMI with new-born anthropometric characteristics and visfatin levels throughout pregnancy. Methods and Material: This longitudinal, observational study on 100 nulliparous pregnant women carried out in Birjand, Iran, over three trimesters in 2016. The researcher asked the participants to fill out the Researcher-made questionnaire including demographic and anthropometric characteristics including first trimester BMI and then referred them to laboratory to serum sample taking from mothers and visfatin levels measurement in the three trimesters. Neonate’s anthropometric measures (weight, height, head circumference and sex of new-borns were obtained from hospital reports. Results: Pearson correlation test indicated significant correlation between birth weight and the first trimester maternal BMI (r= 0.27, P=0.02. Also, Spearman’s correlation test showed a weak negative correlation between head circumference with mean visfatin level (r= -0.23, P=0.04. Linear regression showed that birth weight predicts 28% of variation of BMI. Also, there was significant difference between the maternal level of education and the mean of birth weight (P=0.027. Conclusions: Results of the present study showed that the mean of birth weight was comparable with capital cities in Iran, it is necessary to strengthen the existing mother and child health care program and to develop new approaches.

We wanted to investigate the incidence and the clinicopathologic and sonographic characteristics of thyroid cancers that exhibit positive PET scans. From January 2007 to February 2008, 156 patients with thyroid cancer underwent both sonography and FDG-PET for the purpose of staging the cancer. We conducted a retrospective review of their clinical, radiologic and pathologic records and we evaluated the incidence of PET-positive thyroid cancer, as well as the associated clinicopathologic aggressiveness and the sonographic features. The incidence of PET-positive thyroid carcinoma was 78.2% (122/156). On univariate analysis, PET-positive thyroid cancer was significantly associated with tumor size, extracapsular invasion and central lymph node metastasis, but there was no association between the sonographic features of the thyroid cancer or the sonographic features of the 2 groups of tumor (1. probably benign and 2. suspicious for malignancy) and the FDG uptake. Multivariate logistic regression analysis showed a significant association between PET positivity and both extrathyroidal extension and a higher cancer stage (III/IV) (p < 0.05). The incidence of PET positive thyroid carcinoma is high (78.2%) and PET positivity is significantly associated with tumor size, extracapsular extension and a higher stage. However, there is no significant association between PET positivity and the sonographic features of thyroid carcinoma

BACKGROUND: Prophylaxis with low-dose aspirin may reduce the risk of pre-eclampsia (PE) if introduced in first trimester. The performance of first trimester maternal serum screening for PE using free leptin index (fLI) and PAPP-A, where fLI = leptin/leptin soluble receptor was studied. METHODS: F......: First trimester serum samples from 126 PE pregnancies and 289 control pregnancies were studied. fLI and PAPP-A were converted into gestational age and maternal weight independent log MoM values of PAPP-A and fLI. The screening performance of markers was studied by receiver......-operator-characteristics curves. The performance of population screening was estimated by Monte Carlo simulation. RESULTS: fLI was significantly (p controls [mean log MoM -0.0368 (SD: 0.3132)] and PAPP-A was significantly (p ....0133 (SD: 0.2661)] compared to controls [mean log MoM 0.0474 (SD: 0.2521)] in PE pregnancies. There was no correlation between fLI and PAPP-A in control or PE pregnancies. Combined fLI and PAPP-A screening for PE had estimated population detection rates of 22% and 35% for false positives rates of 6% and 12...

To identify the factors affecting the timeliness of services in first trimester abortion service in New Zealand. Primary data were collected from all patients attending nine abortion clinics between February and May 2009. The outcome measured was delay between the first visit with a referring doctor and the date of the abortion procedure. Patient records (n=2,950) were audited to determine the timeline between the first point of entry to the health system and the date of abortion. Women were also invited to fill out a questionnaire identifying personal factors affecting access to services (n=1,086, response rate = 36.8%). Women who went to private clinic had a significantly shorter delay compared to public clinics. Controlling for clinic type, women who went to clinics that offered medical abortions or clinics that offered single day services experienced less delay. Also, women who had more than one visit with their referring doctor experienced a greater delay than those who had a single visit. The earlier in pregnancy women sought services the longer the delay. Women's decision-making did not have a significant effect on delay. Several clinic level and systemic factors are significantly associated with delay in first trimester abortion services. In order to ensure the best physical and emotional outcomes, timeliness of services must improve. © 2011 The Authors. ANZJPH © 2011 Public Health Association of Australia.

The objective was to determine clinical consequences of anti-D and non-D antibodies undetected at first-trimester screening for infant or fetus. This retrospective cohort study included all pregnant women with red blood cell (RBC) antibodies who were tested between 1993 and 2008. Data were obtained from the forms for tracking immunization at the transfusion department. Each form was analyzed for three data sets: the order of screening at which the antibodies were detected (initial or repeated screening), the order of pregnancy (first pregnancy or higher), and whether the antibodies caused severe hemolytic disease of fetus and newborn (HDFN). In D- women, anti-D was detected in 1.3% of cases. The anti-D was undetected in 72 (37%) cases on the first-trimester screening, of which eight cases were complicated by severe HDFN. In this group, three patients were primigravidae. An overall non-D incidence of 0.2% was observed. In 16 cases, non-D were undetected on the first-trimester screening (10 anti-c, two anti-E, two anti-C, one anti-S, and one case of anti-Rh17). Non-D antibodies undetected on initial screening caused 11 cases of severe HDFN (27% of all severe non-D HDFN). Ten of them were in multiparous women. Seven of 11 cases with severe HDFN that were missed were caused by anti-c. The third-trimester screening may detect RBC antibodies that were not present or detected on the first-trimester screening. Such screening may be especially relevant in D+ multiparous women due to the risk of HDFN. © 2010 American Association of Blood Banks.

Full Text Available Detecting pregnant women at risk of diabetes in first months can help them by early intervention for delaying or preventing onset of GDM. In this study, we aimed to assess the Predictive value of first trimester Pregnancy related plasma protein-A (PAPP-A levels for detecting Gestational diabetes Mellitus (GDM. This systematic review and meta-analysis was conducted through probing in databases. PubMed, Scopus, Medline and Google scholar citations were searched to find the published papers from 1974 to 2017. Studies were considered eligible if they were cohorts, case–control studies, reported GDM result, not other types, conducted on singleton pregnancy, measured Serum pregnancy associated plasma protein A in the first trimester and evaluated the relation of first trimester pregnancy associated plasma protein–A and GDM. Two reviewers independently assessed the quality with Newcastle–Ottawa and extracted data in the Pre-defined checklist. Analysis of the data was carried out by “Comprehensive Meta-analysis Version 2 (CAM” and Metadisc software. 17 articles have our inclusion criteria and were considered in our systematic review, 5 studies included in Meta-analysis. Meta-analysis of these articles showed that the predictive value of PAPP-A for GDM has 55% sensitivity (53–58, 90% (89–90 specificity, LR + 2.48 (0.83–7.36 and LR − 0.70 (0.45–1.09 with 95% confidence intervals. In our study PAPP-A has low predictive accuracy overall, but it may be useful when combined with other tests, and this is an active part for future research. One limitation of our study is significant heterogeneity because of different adjusted variables and varied diagnostic criteria.

This study was performed to present the prenatal sonographic findings and the associated abnormalities of acardiac twins. Seven cases of acardiac twins were reviewed retrospectively. Prenatal ultrasonography was performed in all patients at a gestational age between 12 and 27 weeks (mean 17.6 weeks). Autopsy was performed in four cases. The sonographic and autopsy findings were reviewed to report the associated abnormalities of the acardiac and donor fetuses. The diagnosis of acardiac twins was made on the basis of ultrasonography (n=6) or autopsy (n=1). The associated abnormalities of the acardiac fetuses were single umbilical artery (SUA) (n=5), abdominal wall defect (n=4), club feet (n=4), scoliosis (n=1), cleft lip and palate (n=1), digital anomaly (n=1), and umbilical cord cyst (n=1). In four of the donor fetuses, sonographic abnormalities were found. Autopsy was performed in three of the four cases to reveal hydropic change (n=2), diaphragmatic hernia (n=1) and multiple structural abnormalities of interventricular septal defect, polydactyly, club feet and SUA (n=1). Intrauterine fetal death occurred in five donors and follow-up was lost in the remaining two. Meticulous sonography enables the diagnosis of acardiac twins at an early gestational age and can reveal the associated abnormalities of the donor fetus as well as the acardiac fetus

Full Text Available Nitrogen oxide (NOx is produced during combustion at high temperature, which is a major constituent of air pollutants. Recent studies suggested inconsistent results on the association between NOx exposure and cardiovascular-related malformations. We aimed to assess aforementioned association in pregnant women in the first trimester and cardiovascular-related malformations of infants. A systematic literature review identified studies for observational studies about NOx exposure and cardiovascular-related malformation in PubMed. Random-effect models were used to estimate summary odds ratio (SOR and 95% confidence intervals (CIs for aforementioned association. Finally, nine studies met the inclusion criteria. Overall, the SOR of cardiovascular-related malformation per 10 ppb increment in NOx and NO2 concentration was 1.01 (95% CI: 0.98–1.04; I2 = 38.6%, P=0.09 and 0.99 (95% CI: 0.95–1.04; I2 = 37.8%, P=0.13, respectively. Stratifying by study design, geographic locations, and confounded adjustments, the majority of strata showed negative results, which were consistent with the main findings. However, we found that exposure to NOx and NO2 in the first trimester increased the risk of coarctation of the aorta (COA malformation by 13% and 19%, respectively. Our study provided limited evidence regarding the association between NOx exposure in the first trimester and cardiovascular-related malformations in infants.

The relationship between viral infections and first-trimester spontaneous abortions is not well-understood. The study aim was to investigate the prevalence of cytomegalovirus (CMV), human parvovirus B19 (B19V), and herpes simplex virus-1/2 (HSV-1/2) infection by molecular and serological techniques in women experiencing spontaneous miscarriage in the first trimester of pregnancy. Plasma samples were examined for CMV, B19V, and HSV-1/2 DNA using real-time quantitative polymerase chain reaction (Real-time qPCR), and for specific IgG antibodies against B19V, CMV, and HSV-1/2 using serological assays. The abortion group consisted of women (n = 1,716) with a history of two or more first-trimester spontaneous abortions. Women younger than 30 years possess higher portion to experience spontaneous abortion. No specimens were positive for B19V or CMV DNA. Seven out of the 1,716 specimens were positive for HSV-1/2 DNA. By serology, 47.24% of patients were positive for B19V IgG, 39.66% for HSV IgG, 79.31% for CMV IgG, and 9.31% for B19V IgM. The high rate of positivity for CMV IgG suggests that the majority of women with first-trimester spontaneous abortions are not susceptible to primary CMV infection. The lack of virus DNA in the majority of cases indicates that B19V, CMV, and HSV-1/2 infection is not commonly associated with first-trimester spontaneous abortion. © 2015 Wiley Periodicals, Inc.

Full Text Available Aims. Normal human pregnancy is a complex process of many immunoregulatory mechanisms which protect fetus from the activation of the maternal immune system. The aim of the study was to investigate the apoptosis of lymphocytes in peripheral blood of normal pregnant patients and healthy nonpregnant women. Methods. Sixty pregnant women and 17 nonpregnant women were included in the study. Lymphocytes were isolated and labeled with anti-CD3, anti-CD4, and anti-CD8 monoclonal antibodies. Apoptosis was detected by CMXRos staining and analyzed using the flow cytometric method. Results. We found significantly higher apoptosis of total lymphocytes in peripheral blood of pregnant patients when compared to healthy nonpregnant women. The percentage of apoptotic T CD3+CD8+ cells in the first trimester was significantly higher when compared to the third trimester of normal pregnancy. The ratio of T CD3+CD4+ : T CD3+CD8+ apoptotic lymphocytes was significantly lower in the first trimester when compared to other trimesters of pregnancy and to both of the phases of the menstrual cycle. Conclusions. The higher apoptosis of T CD3+CD8+ lymphocytes and the lower ratio of T CD3+CD4+ : T CD3+CD8+ apoptotic cells in the first trimester of normal pregnancy may suggest a higher susceptibility of T CD3+CD8+ cells for apoptosis as a protective mechanism at the early stage of pregnancy.

Assessment of individual sonographic features provides vital clues about the biological behavior of breast masses and can assist in determining histological grade of malignancy and thereby prognosis. Assessment of individual sonographic features of biopsy proven invasive ductal breast carcinomas as predictors of malignancy grade. A retrospective analysis of sonographic findings of 103 biopsy proven invasive ductal breast carcinomas. Tumor characteristics on gray-scale ultrasound and color flow were assessed using American College of Radiology (ACR) Breast Imaging Reporting and Data System (BI-RADS) Atlas Fifth Edition. The sonographic findings of masses were individually correlated with their histopathologic grades. Chi square test, ordinal regression, and Goodman and Kruskal tau test. Breast mass showing reversal/lack of diastolic flow has a high probability of belonging to histological high grade tumor ( β 1.566, P 0.0001 ). The masses with abrupt interface boundary are more likely grade 3 ( β 1.524, P 0.001 ) in comparison to masses with echogenic halos. The suspicious calcifications present in and outside the mass is a finding associated with histologically high grade tumors. The invasive ductal carcinomas (IDCs) with complex solid and cystic echotexture are more likely to be of high histological grade ( β 1.146, P 0.04 ) as compared to masses with hypoechoic echotexture. Certain ultrasound features are associated with tumor grade on histopathology. If the radiologist is cognizant of these sonographic features, ultrasound can be a potent modality for predicting histopathological grade of IDCs of the breast, especially in settings where advanced tests such as receptor and molecular analyses are limited.

To analyze the related sonographic findings and to determine the value of sonography in establishing the diagnosis of acute osteomyelitis in infants. The sonographic findings of eleven infants aged 10 days-4 months (mean, 45 days) with acute osteomyelitis were retrospectively evaluated. The involved bones were the femur (n=5), humerus (n=2), tibia (n=2), rib(n=1), sternum (n=1), and calcaneus (n=1). Discontinuity or destruction of cortical margins, echotexture of the metaphysis and epiphysis, the presence of subperiosteal hypoechoic lesion, adjacent soft tissue swelling, distension of the joint capsule, the echotexture of joint effusion, and dislocation or subluxation of the involved joint were evaluated. The sonographic findings were compared with the plain radiographic (n=12) and MR (n=5) findings, with special attention to the identification of the metaphyseal or epiphyseal bony lesions and the involvement of adjacent joints. The sonographic findings of osteomyelitis were cortical discontinuity or destruction (n=12), hypoechoic lesions with an echogenic rim in the metaphysis (n=12), subperiosteal hypoechoic lesions (n=8), soft tissue swelling (n=9), a distended hip joint, with echogenic fluid (n=5), ill-demarcated echogenic lesions in the capital femoral epiphysis (n=5), and a subluxated hip joint (n=3). Plain radiographs revealed well or ill-defined osteolytic lesions in the metaphysis, accompanied by cortical destruction (n=8), new periosteal bone formation (n=3) and reactive sclerosis (n=2). Abnormality of the femoral epiphyses and joint involvement were not detected on plain radiographs, and in four cases no abnormality was noted. MR imaging showed that at T1WI, affected bony lesions were of low signal intensity and enhaned, with high signal intensity at T2WI. In all cases, both metaphyseal and epiphyseal lesions were demonstrated at MRI, but in one of the three cases in which an epiphyseal lesion was seen at MRI, this was not detected at US.

To correlate the atypical sonographic patterns of fibroadenoma of the breast with the pathologic findings. Among 203 surgically proven 43 which were sonographically atypical fibroadenomas, were retrospectively reviewed. The diagnostic criteria for atypical variety, as seen on sonography, were an ill-defined margin, microlobulated or irregular shape, heterogeneous internal echo-pattern, posterior shadowing, microcalcification, and clefts. The atypical sonographic patterns of these 43 fibroadenomas were analysed and compared with the pathologic findings. Among 43 lesions, ill-defined margins or irregular shapes were seen in 15 cases, heterogeneous internal echo-patterns in 27, posterior attenuation in nine, and clefts in seven. Thirty-seven (86%) of the 43 were predominantly ductal or had a mixed ductal and stromal component. Eleven (73.3%) of fifteen ill-defined margin or irregular shaped lesions were caused by interdigitation of surrounding normal breast parenchyma and mass. Twenty two (81.5%) of 27 heterogeneous internal echo-pat-terns were related to dilated ducts, phyllodes features, collagen bundles, adenosis, microcalcification, or fat vacuoles. Eight (88.9%) of nine posterior attenuations were caused by collagen bundles, microcalcification, ductal proliferation or dilatation. All seven cases showing clefts revealed phyllodes features and dilated ducts. Most atypical fibroadenomas had a predominantly ductal or mixed component. Ill-defined margin or irregular shape was mainly due to interdigitation of normal surrounding parenchyma. Variable histologic features were related to the heterogeneous internal echo-pattern, posterior shadowing, and the clefts revealed by atypical sonographic findings.

Purpose To compare the cytological results of ultrasound-guided fine-needle aspiration (US-FNA) cytology of thyroid nodules to sonographic findings and determine whether US findings are helpful in the interpretation of cytological results. Materials and Methods Among the thyroid nodules that underwent US-FNA cytology, we included the 819 nodules which had a conclusive diagnosis. Final diagnosis was based on pathology from surgery, repeated FNA cytology or follow-up of more than one year. Cytological results were divided into five groups: benign, indeterminate (follicular or Hurthle cell neoplasm), suspicious for malignancy, malignant, and inadequate. US findings were categorized as benign or suspicious. Cytological results and US categories were analyzed. Results Final diagnosis was concluded upon in 819 nodules based on pathology (n=311), repeated FNA cytology (n=204) and follow-up (n=304), of which 634 were benign and 185 were malignant. There were 560 benign nodules, 141 malignant nodules, 49 nodules with inadequate results, 21 with indeterminate results, and 48 that were suspicious for malignancy. The positive and negative predictive values of the US categories were 59.1% and 97.0%, and those of the cytological results were 93.7% and 98.9%. The US categories were significantly correlated with final diagnosis in the benign (p=0.014) and suspicious for malignancy (pcytological result groups, but not in the inadequate and indeterminate cytological results groups. The false positive and negative rates of cytological results were 1.9% and 3.2%. Conclusion Sonographic findings can be useful when used alongside cytological results, especially in nodules with cytological results that are benign or suspicious for malignancy. PMID:21786450

In 2005 Ethiopia took the important step to protect women's reproductive health by liberalizing the abortion law. As a result women were given access to safe pregnancy termination in first and second trimester. This study aims to describe socio-economic characteristics and contraceptive experience among women seeking abortion in Jimma, Ethiopia and to describe determinants of second trimester abortion. A cross-sectional study conducted October 2011 - April 2012 in Jimma Town, Ethiopia among women having safely induced abortion and women having unsafely induced abortion. In all 808 safe abortion cases and 21 unsafe abortion cases were included in the study. Of the 829 abortions, 729 were first trimester and 100 were second trimester abortions. Bivariate and multivariate logistic regressions were used to determine risk factors associated with second trimester abortion. The associations are presented as odds ratios (OR) with 95% confidential intervals. Age stratified analyses of contraceptive experience among women with first and second trimester abortions are also presented. Socio-economic characteristics associated with increased ORs of second trimester abortion were: age abortion where only 15% and 19% stated they had ever used contraception. Young age, poor education and the prospect of single parenthood were associated with second trimester abortion. Young girls and young women were using contraception comparatively less often than older women. To ensure women full right to control their fertility in the setting studied, modern contraception should be made available, accessible and affordable for all women, regardless of age.

2018-01-01

Full Text Available Context: Assessment of individual sonographic features provides vital clues about the biological behavior of breast masses and can assist in determining histological grade of malignancy and thereby prognosis. Aims: Assessment of individual sonographic features of biopsy proven invasive ductal breast carcinomas as predictors of malignancy grade. Settings and Design: A retrospective analysis of sonographic findings of 103 biopsy proven invasive ductal breast carcinomas. Materials and Methods: Tumor characteristics on gray-scale ultrasound and color flow were assessed using American College of Radiology (ACR Breast Imaging Reporting and Data System (BI-RADS Atlas Fifth Edition. The sonographic findings of masses were individually correlated with their histopathologic grades. Statistical Analysis Used: Chi square test, ordinal regression, and Goodman and Kruskal tau test. Results: Breast mass showing reversal/lack of diastolic flow has a high probability of belonging to histological high grade tumor ( β 1.566, P 0.0001. The masses with abrupt interface boundary are more likely grade 3 ( β 1.524, P 0.001 in comparison to masses with echogenic halos. The suspicious calcifications present in and outside the mass is a finding associated with histologically high grade tumors. The invasive ductal carcinomas (IDCs with complex solid and cystic echotexture are more likely to be of high histological grade ( β 1.146, P 0.04 as compared to masses with hypoechoic echotexture. Conclusions: Certain ultrasound features are associated with tumor grade on histopathology. If the radiologist is cognizant of these sonographic features, ultrasound can be a potent modality for predicting histopathological grade of IDCs of the breast, especially in settings where advanced tests such as receptor and molecular analyses are limited.

To estimate the predictive value of first-trimester mean arterial pressure (MAP) for the hypertensive disorders of pregnancy (HDP). We performed a prospective cohort study of nulliparous women recruited at 11 0/7 -13 6/7  weeks. MAP was calculated from blood pressure measured on both arms simultaneously using an automated device taking a series of recordings until blood pressure stability was reached. MAP was reported as multiples of the median adjusted for gestational age. Participants were followed for development of gestational hypertension (GH), preeclampsia (PE), preterm PE (curves and the area under the curve (AUC) were used to estimate the predictive values of MAP. Multivariate logistic regressions were used to develop predictive models combining MAP and maternal characteristics. We obtained complete follow-up in 4700 (99%) out of 4749 eligible participants. GH without PE was observed in 250 (5.3%) participants, and PE in 241 (5.1%), including 33 (0.7%) preterm PE and 10 (0.2%) EO-PE. First-trimester MAP was associated with GH (AUC: 0.77; 95%CI: 0.74-0.80); term PE (0.73; 95%CI: 0.70-0.76), preterm PE (0.80; 95%CI: 0.73-0.87) and EO-PE (0.79; 95%CI: 0.62-0.96). At a 10% false-positive rate, first-trimester MAP could have predicted 39% of GH, 34% of term PE, 48% of preterm PE and 60% of EO-PE. The addition of maternal characteristics improved the predictive values (to 40%, 37%, 55% and 70%, respectively). First-trimester MAP is a strong predictor of GH and PE in nulliparous women.

2010-01-01

Background: Pregnant Nigeria women are usually anxious about the gender of their fetuses for social reasons. Objective: The purpose of this study was to determine the accuracy of ultrasound in the determination of fetal gender in women who wished to know the gender of their fetuses and in those whom the gender of their fetuses were requested for on clinical grounds in the second and third trimesters. Methods: A prospective longitudinal study was performed on 1480 singleton pregnancies who met the inclusion criteria between February 2004 and January 2008. Ultrasound examination was performed on GE ALOKA 500 machine, transabdominally between 14 and 40 weeks gestational age (GA). Both transverse and mid-sagittal planes of a section of the fetal genital tubercle were performed to identify the gender. The subsequent gender at birth was obtained from the hospital birth records. Results: During the study, 1211 (81.8%) women requested gender information while the gender information from 269 (18.2%) women was requested for on clinical grounds. The mean GA at which the fetuses were scanned was 29 +2 ± 3 +6 weeks (range 14-40 weeks). Fetal gender assignment was possible in 1350 (91.2%) out of 1480 fetuses; 680 assigned male and 670 female. Of these, the fetal gender corroborated birth sex in 1325 (89.5%) and disagreed in 25 (1.7%) cases. The overall estimated sensitivity of the scan is 98.1%, while the estimated specificity for identification of the male sex (100%) was higher than the female (78.3%). Of the 130 cases where no identification of gender was possible, 50 were in the second trimester and 80 were in the third trimester. Conclusion: This study demonstrated that the accuracy of fetal gender determination increased with gestational age, from 97.1% in the second trimester to 98.5% in the third trimester. The overall fetal gender accuracy rate for male fetus was better than female and was statistically significant (P < 0.05).

Metformin is generally considered a non-teratogenic drug; however, only a few studies specifically designed to assess the rate of congenital anomalies after metformin use have been published in the literature. The objects of the present study were to review all of the prospective and retrospective studies reporting on women treated with metformin at least during the first trimester of their pregnancy and to estimate the overall rate of major birth defects. Databases were searched for English language articles until December 2013. Inclusion criteria for the meta-analysis were: a case group of women with PCOS or pre-pregnancy type 2 diabetes and first-trimester exposure to metformin; a disease-matched control group which was not exposed to metformin or other oral anti-diabetic agents; and a list of the major anomalies in both the study and the control groups. A random effects model was used for the meta-analysis of data, using odds ratios. Studies not fulfilling the inclusion criteria for the meta-analysis but reporting relevant data on major malformations in women diagnosed with PCOS were then used to estimate the overall birth defects rate. Meta-analysis of nine controlled studies with women affected by PCOS detected that the rate of major birth defects in the metformin-exposed group was not statistically increased compared with the disease-matched control group and that there was no significant heterogeneity among the studies. The metformin-exposed sample was composed of 351 pregnancies and the OR of major birth defects was 0.86 (95% confidence interval: 0.18-4.08; Pheterogeneity = 0.71). By evaluating all of the non-overlapping PCOS studies reported in the literature, even those without an appropriate control group, the overall rate of major anomalies was 0.6% in the sample of 517 women who discontinued the therapy upon conception or confirmation of pregnancy and 0.5% in the sample of 634 women who were treated with metformin throughout the first trimester of

2014-10-01

We tested whether antihistamine exposure during early pregnancy is associated with spontaneous abortion (SAB) or preterm birth (PTB). Women were enrolled in Right from the Start (2004-2010), a prospective pregnancy cohort. Data about first-trimester antihistamine use were obtained from screening and first-trimester interviews. Self-reported outcomes included SAB and PTB and were verified by medical records. Cox proportional hazards models were used to test for an association between antihistamine use and each outcome, both performed adjusting for confounders. Among the 2685 pregnancies analyzed, 14% (n = 377) reported use of antihistamines. Among antihistamine users, 12% (n = 44) experienced SABs, and 6% (n = 21) had PTBs. Antihistamine exposure was not associated with SAB (adjusted hazard ratio [aHR] = 0.88, 95% confidence interval [CI] 0.64, 1.21) or PTB, which was modified by maternal race (aHR = 1.03, 95%CI 0.61, 1.72 among White women and aHR = 0.43, 95%CI 0.14, 1.34 among Black women). Despite the biologic plausibility that antihistamine use may influence pregnancy outcomes, we did not detect evidence of an association with SAB or PTB. These data demonstrate the utility of large prospective cohorts for evaluating drug safety in pregnancy when concerns are raised from animal models. Copyright © 2014 John Wiley & Sons, Ltd.

To obtain the characteristic sonographic findings of ovarian hemorrhage and investigate the usefulness of ultrasonography in the diagnosis. Forty-nine cases presenting acute abdomen diagnosed as ovarian hemorrhage by ultrasonography or surgicopathological confirmation. We observed the size and margin of the ovary, size, pattern, shape, wall and internal echogenecity of the masses and the amount of hemoperitoneum. We also performed a color Doppler study to evaluate the blood flow pattern and resistive index (RI). The age of patients were between 21-41. Most symptoms occurred from days 14 to 30 of her menstrual cycle and were presented for less than 24 hours. Twenty patients had a history of intercourse shortly before the onset of the symptom. Thirty two cases involved the right ovary while the other 17 cases involved the left. All patients had a negative urine or serum hCG test except for 4 pregnant women. The size of the ovary was measured as mean 5.1 cm and marginal irregularly was noted in 36 cases. Mixed echoic solid masses were observed in 6 cases and variable echogenecity of cystic masses were seen in 43 cases. Maximal diameter of adnexal masses were measured as mean 3.95 cm. Internal echogenecity of cystic masses appeared as mainly heterogeneous (21). Twenty two cystic masses had a thick irregular wall and 17 had a thin smooth wall. Hypoechoic rim like halo surrounding was noted in 17 cystic masses. 17 cases seemed to have a small amount of hemoperitoneum, a moderate amount in 22 cases and a large amount in 9 cases. The blood flow pattern of cystic masses showed a rim (29) and spotty (8) pattern in the color Doppler study. Measured RI was 0.41 (mean). Fertile women with the complaint of acute abdominal pain, who has the laboratory data of negative hCG test, ultrasonographic findings of enlargement of ovary with irregular margin, heterogeneous echoic cystic mass, peripheral halo surrounding the mass, hemoperitoneum and low resistance index of peripheral blood

Pneumobilia is one of the most troublesome problem in the sonographic examination of the hepatobiliary system, and the differentiation of air from intrahepatic stone is very important. We have analyzed the sonographic characteristics of 42 cases of pneumobilia dn 56 cases of intrahepatic stones over a period of 4 years. New findings of pneumobilia we observed were U.F.O. sign, wing like artefact, and nonvisualization of the lumen of the bile filled duct. Findings of pneumobilia only were U.F.O. sign, nng down and wing like artefact. Findings of stone only were ecdhogenic foci larger than 1.5cm, heterogeneous echo, wedge, shell, or sandwich like contour, and visible lumen of the bile duct

OBJECTIVES: To assess cervical length (CL) longitudinally in the first and second trimester and to determine the proportion of women with a short CL. Further, to assess if women with a short CL at 19-24 weeks could be identified at the combined first-trimester screening (cFTS) at 11-14 weeks...... in relation to a potential implementation of CL screening in the Danish population. METHODS: We recruited singleton pregnant women attending the combined first-trimester screening from 1 November 2013 to 1 December 2014 to a longitudinal prospective study at three University Hospitals in Denmark. We excluded...... women with multiple pregnancies, uterine anomalies, cerclage, or progesterone treatment at inclusion. CL was measured by transvaginal sonography at 11-14 weeks (Cx1), 19-21 weeks (Cx2) and 23-24 weeks (Cx3). CL was measured as a straight line from the external to internal os by trained operators.

Insulin resistance (IR) has been reported to play an important role in recurrent spontaneous abortion (RSA) among patients with polycystic ovary syndrome (PCOS). However, scanted materials exist regarding the independent effect of IR on RSA. The aim of this study is to investigate the status of IR in first trimester pregnant patients with normal pre-pregnant glucose tolerance and history of RSA. This two-center case-control study enrolled totally 626 first trimester pregnant women including 161 patients with a history of recurrent spontaneous abortion, who were pre-pregnantly glucose-tolerant according to oral glucose tolerance test (OGTT), and 465 women with no history of abnormal pregnancies of any kind. Clinical, biochemical and hormonal parameters were simultaneously measured in all participants. Serum beta-HCG, estradiol, progesterone, fasting plasma glucose and fasting plasma insulin levels, as well, the calculated homeostasis model assessment of insulin resistance index (HOMA-IR), fasting plasma glucose/insulin ratio(G/I) and pregnancy outcome were analyzed and compared. Serum beta-HCG and progesterone were found to be significantly lower in RSA group compared to controls. Subjects in RSA group were found to have higher HOMA-IR and lower G/I ratio than those in control group. Serum beta-HCG and progesterone were negatively correlated with HOMA-IR, and positively with G/I ratio even after adjustment for BMI. The spontaneous abortion rate within first trimester pregnancy of RSA patients was significantly higher than that in controls. In conclusion, woman with recurrent spontaneous abortion and normal pre-pregnant glucose metabolism tends to be more insulin resistant during first trimester pregnancy than healthy controls, no matter whether she has PCOS or not. Insulin resistance might be one of the direct causes that lead to recurrent abortion.

Full Text Available To study the associations between maternal consumption of non-staple food in the first trimester and risk of neural tube defects (NTDs in offspring. Data collected from a hospital-based case-control study conducted between 2006 and 2008 in Shandong/Shanxi provinces including 459 mothers with NTDs-affected births and 459 mothers without NTDs-affected births. Logistic regression models were used to examine the associations between maternal consumption of non-staple food in the first trimester and risk of NTDs in offspring. The effects were evaluated by odds ratio (OR and 95% confidence intervals (95% CIs with SAS9.1.3.software. Maternal consumption of milk, fresh fruits and nuts in the first trimester were protective factors for total NTDs. Compared with consumption frequency of ˂1 meal/week, the ORs for milk consumption frequency of 1–2, 3–6, ≥7 meals/week were 0.50 (95% CI: 0.28–0.88, 0.56 (0.32–0.99, and 0.59 (0.38–0.90, respectively; the ORs for fresh fruits consumption frequency of 1–2, 3–6, ≥7 meals/week were 0.29 (95% CI: 0.12–0.72, 0.22 (0.09–0.53, and 0.32 (0.14–0.71, respectively; the ORs for nuts consumption frequency of 1–2, 3–6, ≥7 meals/week were 0.60 (95% CI: 0.38–0.94, 0.49 (0.31–0.79, and 0.63 (0.36–1.08, respectively. Different effects of above factors on NTDs were found for subtypes of anencephaly and spina bifida. Maternal non-staple food consumption of milk, fresh fruits and nuts in the first trimester was associated with reducing NTDs risk in offspring.

The great majority of lymphangiomas occur in the neck (75%) and axilla (20%), but extremity lymphangioma is rare. We correlate variable sonographic features of extremity lymphangioma with pathologic findings. We reviewed the sonographic findings of extremity lymphangioma in 14 patients (M:F=8:6). The all cases were histologically confirmed by operation. The variable sonographic features of extremity lymphangioma were compared to pathologic findings. The multilocular cystic mass with ill defined boundaries was distinctive sonographic appearance of extremity lymphangioma. But there were variable sonographic findings such as heterogeneous echogenic mass or homogeneous echogenic portion. The histologic section of echogenic lesion reveals clusters of abnormal

groups. Free β-hCG (MoM) ± SEM differed significantly (1.55 ± 0.19 in Vitrolife versus 1.06 ± 0.10 in Cook; P = 0.031, Student's t-test). At 20 weeks' gestation, a more advanced GA, reflecting an increased fetal growth, was seen at ultrasound examination in the Vitrolife group (n = 115) when compared with the Cook group (n = 91). After adjustment for confounding factors, both the difference between GA based on three biparietal diameter dating formulas minus the actual (ovum retrieval based) GA (adjusted mean difference + 1.14 days (P = 0.04), +1.14 days (P = 0.04) and +1.36 days (P = 0.048)), as well as head circumference (HC) and trans-cerebellar diameter (TCD) were significantly higher in the Vitrolife group (HCvl 177.3 mm, HCc 175.9 mm, adjusted mean difference 1.8, P = 0.03; TCDvl 20.5 mm, TCDc 20.2 mm, adjusted mean difference 0.4, P = 0.008). A first trimester (12 weeks) fetal screening was not yet offered routinely during the study period, therefore only 28% of women in our study participated in this elective screening programme. Although all sonographers were experienced and specially trained to perform these ultrasound examinations and were unaware of the randomization procedure, we cannot totally rule out possible intra- and inter-observer variability. Despite being indispensable in daily practice, sonographic weight formulas have a limited accuracy. According to the fetal origins hypothesis, many adult diseases originate in utero owing to adaptations made by the fetus to the environment it encounters. This study indicates that the embryonic environment is already important for fetal development. Therefore, our study emphasizes the need to investigate fetal growth patterns after assisted reproduction technologies and long-term health outcomes of IVF children, especially in relation to the culture medium used during the first few days of preimplantation development.

Objective was to assess the effectiveness of misoprostol in cervical ripening before evacuation of conception in the first trimester missed miscarriages and to compare between oral and vaginal routes of administration. A randomized control study was carried out in Baghdad Teaching Hospital, Baghdad, Iraq in 2006. One hundred and twenty women with first fist trimester missed miscarriages were divided into 2 study groups, randomized for oral and vaginal (400 mcg) misoprostol priming of cervix and 2 control groups randomized for oral and vaginal placebo, before undergoing surgical evacuation of conception after 3 hours. Measured outcomes were: post medication cervical dilatation, time needed to dilate the cervix surgically, blood loss and developments of the side effects of misoprostol. Post medication cervical dilation was higher in the misoprostol group (7.07+-1.36 mm for oral misoprostol, 7.77+-1.22 mm for vaginal misoprostol), versus the control groups (2.43+-0.5 mm). Post medication cervical dilatation was significantly higher in the vaginal misoprostol group, compared to the oral group (p=0.04). The time required to dilate the cervix in the misoprostol group was shorter, compared with placebo. There were no significant differences in the amount of blood loss between oral (p=0.074) and vaginal misoprostol groups (p=0.62) and gastrointestinal side effects were significantly more in the oral misoprostol group (p=0.014). Misoprostol is an effective cervical priming agent when administered either orally or vaginally before evacuation of conception in the termination of the first trimester missed miscarriage. (author)

Detecting pregnant women at risk of diabetes in first months can help them by early intervention for delaying or preventing onset of GDM. In this study, we aimed to assess the Predictive value of first trimester Pregnancy related plasma protein-A (PAPP-A) levels for detecting Gestational diabetes Mellitus (GDM). This systematic review and meta-analysis was conducted through probing in databases. PubMed, Scopus, Medline and Google scholar citations were searched to find the published papers from 1974 to 2017. Studies were considered eligible if they were cohorts, case-control studies, reported GDM result, not other types, conducted on singleton pregnancy, measured Serum pregnancy associated plasma protein A in the first trimester and evaluated the relation of first trimester pregnancy associated plasma protein-A and GDM. Two reviewers independently assessed the quality with Newcastle-Ottawa and extracted data in the Pre-defined checklist. Analysis of the data was carried out by "Comprehensive Meta-analysis Version 2 (CAM)" and Metadisc software. 17 articles have our inclusion criteria and were considered in our systematic review, 5 studies included in Meta-analysis. Meta-analysis of these articles showed that the predictive value of PAPP-A for GDM has 55% sensitivity (53-58), 90% (89-90) specificity, LR + 2.48 (0.83-7.36) and LR - 0.70 (0.45-1.09) with 95% confidence intervals. In our study PAPP-A has low predictive accuracy overall, but it may be useful when combined with other tests, and this is an active part for future research. One limitation of our study is significant heterogeneity because of different adjusted variables and varied diagnostic criteria. Copyright © 2018. Published by Elsevier B.V.

Full Text Available This article reviews recently published studies investigating the MRI and sonographic diagnosis of masticatory muscle myalgia in temporomandibular disorder patients. The MRI and sonographic features of muscle after treatment are also discussed. Literature published within the last 15 years was obtained from the PubMed database using the following Mesh terms: magnetic resonance imaging (MRI or sonography, masticatory muscle pain, and treatment. MRI and sonography enable accurate visualization and evaluation of the masticatory muscles, thereby increasing our understanding of pathology and cause of pain associated with these muscles. Although therapeutic efficacy is often evaluated based on clinical findings, MR and sonographic imaging studies may also be valuable.

The aim of this study was to investigate the prevalence of xenobiotic substances, such as caffeine, nicotine and illicit drugs (eg, cannabis and cocaine), in blood samples from first-trimester Danish pregnant women unaware of the screening. A cross - sectional study examined 436 anonymised residual blood samples obtained during 2014 as part of the nationwide prenatal first-trimester screening programme. The samples were analysed by ultra performance liquid chromatography with high-resolution time-of-flight mass spectrometry. An antenatal clinic in a Danish city with 62 000 inhabitants, where >95% of pregnant women joined the screening programme. The prevalence and patterns of caffeine, nicotine, medication and illicit drug intake during the first trimester of pregnancy. The prevalence of prescription and over-the-counter drug detection was 17.9%, including acetaminophen (8.9%) and antidepressants (3.0%), of which citalopram (0.9%) was the most frequent. The prevalence of illegal drugs, indicators of smoking (nicotine/cotinine) and caffeine was 0.9%, 9.9%, and 76.4%, respectively. Only 17.4% of women had no substance identified in their sample. This study emphasises the need for further translational studies investigating lifestyle habits during pregnancy, as well as the underlying molecular mechanisms through which xenobiotic substances may affect placental function and fetal development. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

1999-01-01

To correlate sonographic appearance and histopathologic findings of fibroadenomas. Forty-one biopsy-proven fibroadenomas were retrospectively evaluate for sonographic-pathologic correlation. The fibroadenomas were histologically classified into sclerotic, myxoid, glandular and mixed type. The stromal cellularity and fibrosis were also classified into mild and severe. The internal echotexture and posterior acoustic enhancement of mass in ultrasonogram were correlated with histopathologic findings. The pathologic types of fibroadenomas were sclerotic in sixteen, myxoid in thirteen, and glandular or mixed in each of six cases. Most of the sclerotic type showed hypoechoic internal echotexture (68.8%) and myxoid and glandular types showed isoechoic internal echotexture (84.6%, 83.3% respectively). The hypoechoic masses showed 12 cases of mild (75.0%) and 4 cases of severe (25.0%) in cellularity and 3 cases of mild (18.7%) and 13 cases (81.3%) of sever degree in fibrosis. Most of the myxoid type (77%) showed posterior enhancement, and most of the sclerotic type (87.5%) did not show posterior enhancement on ultrasonogram. Posterior enhancement was absent in 22 cases, in which 4 cases (18.2%) showed mild and 18 cases (81.2%) showed severe degree of fibrosis. Sclerotic type with mild cellularity and severe fibrosis on histopathology showed hypoechogenicity on ultrasonogram; whereas myxoid and glandular types were predominantly isoechoic. Most of the myxoid type showed posterior enhancement. Sclerotic type with mild cellularity and severe fibrosis did not show posterior enhancement.

First trimester prenatal cytogenetic diagnosis was attempted in 350 pregnancies after transabdominal chorionic villus sampling. The cytogenetic investigation was performed using both a short-term method (24 h incubation) and cell culture. Adequate samples were obtained in 99.1 per cent and in all...... of 181 cases where the 24 h incubation revealed a male karyotype. Studies of culture morphology showed that colonies of convoluted cells may serve as a marker for contamination with maternal cells in culture. For the present, we recommend using a short-term method as well as cell culture for cytogenetic...

Choi, Bo Bae; Shu, Kwang Sun

2012-01-01

The purpose of this study was to evaluate the mammographic and sonographic findings of pure sclerosing adenosis. We retrospectively reviewed the mammographic and sonographic findings in 40 cases of pure sclerosing adenosis confirmed by core needle biopsy (n = 23), vacuum-assisted biopsy (n = 7), excision biopsy (n = 9), and lumpectomy (n = 1) from January 2002 to March 2010. All imaging findings were analyzed according to the American College of Radiology (ACR) breast imaging reporting and data system (BI-RADS). Radiologic features were correlated with pathologic findings. Although most mammograms showed negative findings (57%), calcification was the most common abnormal finding of sclerosing adenosis. On sonography, the most common finding was a circumscribed oval hypoechoic mass without posterior features (78%). Most masses showed BI-RADS category 3, (75%, 27/36). Five cases showed categories 4 or 5 (14%, 5/36). Most mammographic and sonographic findings of sclerosing adenosis are non-specific and non-pathognomonic, even though sometimes sclerosing adenosis can be radiologically or histopathologically confused with malignancy

Early diagnosis of ruptured and unruptured tubal pregnancy became more accurate with the introduction of transvaginal sonographic equipment. The management principle of tubal pregnancy might be changed according to the sonographic findings. The purposes of this study were to define the sonographic findings of tubal pregnancy and to determine whether it is possible to differentiate the unruptured tubal pregnancies from the ruptured ones depending on the sonographic findings. The authors investigated the sonographic findings of the surgically confirmed 25 tubal pregnancy patients. There were 22(88%) unruptured and 3(12%) ruptured tubal pregnancies. Unruptured pregnancies showed tubal ring in 8, well defined hematosalpinx in 11, and poorly defined hematosalpinxin 2 patients. Ruptured pregnancies showed tubal sac with irregular margin in 2, and ill-defined hematosalpinx in one patient. In summary, well marginated tubal ring and hematosalpinx suggested unruptured tubal pregnancy, while tubal sac with irregular margin suggested ruptured pregnancy. However, it was difficult to differentiate the unruptured tubal pregnancy from the ruptured one when hematosalpinx was ill-defined

Sufficient iodine intake is needed during pregnancy to ensure proper fetal development. The iodine levels of women in their first trimester of pregnancy in Catalonia are currently unknown. This data would help to determine whether our public health services should establish recommendations or interventions in this line. The aim of this study was to investigate the iodine nutritional status, prevalence of urinary iodine pregnancy in our setting. Cross-sectional study. Data were collected during 2008-2009 from women in their first trimester at the primary care centers of the province of Barcelona (Spain). Pregnant women included in the study completed a questionnaire on eating habits and underwent urinary iodine concentration (UIC) assessment. Nine hundred forty five women completed the dietary questionnaire and urinary iodine testing. Median UIC was 172 μg/L, with 407 participants (43.1%) showing levels 2 glasses, OR = 0.593 95% CI (0.37-0.95); iodized salt consumption, OR = 0.678 95% CI (0.51-0. 90); and use of iodine supplementation, OR = 0.410 95% CI (0.31-0.54), protected against the risk of UIC nutritional status according to the criteria established by the WHO and ICCIDD. The risk of urinary iodine <150 μg/L decreased with simultaneous consumption of milk and iodized salt, similar to the decrease seen with iodine supplementation.

Elevated CRP levels during first trimester of pregnancy and subsequent preeclampsia: a prospective study

Directory of Open Access Journals (Sweden)

Beigi A

2008-06-01

Full Text Available Background: Whatever its etiology, the inflammatory reactions of preeclampsia lead to the activation of endothelium and result in vascular damage. CRP is considered a sensitive index of systemic inflammation, so it is used as predictive factor for disease. This study was carried out to test the screening and predictive abilities of the CRP test in order to detect and diagnose pregnant women prone to preeclampsia prior to the onset of symptoms.Methods: In this prospective cohort study, conducted in Arash Hospital between 2005 and 2006, we determined the CRP levels of 201 pregnant women at 10-16 weeks of pregnancy. Based on exclusion criteria and illness, 31 patients were excluded and 170 patients were followed until the end of their pregnancies.Results: In this study, the mean serum CRP values of those who had preeclamptic and those who had normal pregnancies were compared and the statistical differences were significant: 6.18 mg/L for preeclamptic patients compared with 4.12 mg/L for normal patients (p=0.003. Using a chi-square test, we found that patients whose CRP level was ≥4 were six times more likely to have preeclampsia than those with CRP levels <4 (k=9.4; p=0.002; OR=6.15; 95% CI=0.69-22.28.Conclusion: This study confirms the results of previous reports indicating a significant relationship between rising serum CRP in the first trimester of pregnancy and preeclampsia at third trimester. More studies consisting of other inflammation factors are necessary to find an acceptable and reasonable screening test to diagnose pregnant women who are prone to preeclampsia.

Typical cavernous hemangioma presents no diagnostic difficulty at sonography. However, in cases of atypical hemangioma, further evaluation is needed to differentiate it from malignancy. On the other hand, thcechogenicity of the lesion may be iso echo or hypoecho when it occurs in association with fatty liver. We analyzed the sonographic features of hemangioma in fatty liver. We reviewed the sonograms of 22 lesions from 19 patients. We divided the lesions into two groups; the lesion measuring less than 3cm in diameter (group I) and the lesions measuring same or greater than 3cm (group II). The lesions of each group were analyzed in terms of location, shape, distinction of margin, internal echogenicity, posterior enhancement, lateral shadowing, and peritumoral hypoechoic halo. The lesions were located in subcapsular or perivascular areain 86%. They strowed round or lobulated shape with well defined margin in 82%. Internal echo of the lesions was hypoechoic in 82% and homogeneous in 64%. Posterior enhancement was seen in 77%. The posterior wall of the lesion was distinct in 68%. There was no statistical difference in incidence of each finding described above between the two groups except the internal echogenicity(p<0.05). All of the four hyperechoic lesions measured greater than 3cmin diameter, and three of them showed uneven thickness of echogenic rind. Definitive diagnosis of hemangioma could be obtained in 82%. In remaining 18% of hemangioma, the lesions showed peripheral hypoechoic halo and lateral shadowing that made the diagnosis of hemangioma difficult. However, the possibility of hemangioma could be suggested because they showed haemangiomas internal eye-catching and posterior enhancement. Hepatic cavernous hemangioma presents with variable eye-catching as compared to the surrounding tissue when it is associated with fatty liver disease, Thus, in differentiating hemangiomas from other localized hepatic mass, other characteristics such as homogeneity of the

Full Text Available Acute pancreatitis is rare in pregnancy, with an estimated incidence of approximately 1 in 1000 to 1 in 10,000 pregnancies. Acute pancreatitis in pregnancy usually occurs in the third trimester. Here, we report a case of acute pancreatitis in the first trimester. A 36-year-old primigravida at 11 weeks of gestation complained of severe lower abdominal pain. The pain gradually worsened and migrated toward the epigastric region. She had no history of chronic alcoholism. Blood investigations showed elevated level of C-reactive protein (9.58 mg/dL, pancreatic amylase (170 IU/L, and lipase (332 IU/L. There was no gallstone and no abnormality in the pancreatic and biliary ducts on ultrasonography. Antinuclear antibody and IgG4 were negative and no evidence of hyperlipidemia or diabetes was found. There was also no evidence of viral infection. On the third day of hospitalization, she was diagnosed with severe acute pancreatitis on magnetic resonance imaging. Medical interventions were initiated with nafamostat mesilate and ulinastatin, and parenteral nutrition was administered through a central venous catheter. On the eighth day of hospitalization, her condition gradually improved with a decreased level of pancreatic amylase and the pain subsided. After conservative management, she did not have any recurrence during her pregnancy.

To identify typical sonographic semiotics of ureterohydronephrosis in children having importance in determining the severity of disease and the choice of treatment strategy in this category of patients. Sonographic images of the kidneys and urinary tract of 158 children with ureterohydronephrosis were examined. Unilateral and bilateral ureterohydronephrosis was found in 75 and 83 children, respectively. There were 100 (63.3%) boys and 58 (36.7%) girls. The age of patients ranged from 3 months to 14 years (mean 4.15+/-3.21). Ultrasound examination enables the upper 193 (80.1%) and lower 167 (69.3%) third of ureters to be visualized. At the same time more than half of the visualized ureters had a diameter greater than 1 cm, and one-tenth of the affected ureters had diameters greater than 2 cm. If direct visualization of the ureters was impossible, pelvicalyceal system was evaluated, which was expanded on the affected side in all examined children. The morpho-sonographic changes of renal parenchymal in children with III-IV degree ureterohydronephrosis are described in details. Ultrasound examination can be regarded as a screening method for initial evaluation of patients with ureterohydronephrosis. It provides a rough estimation of the extent, level and nature of disturbances of urinary excretion, a preliminary assessment of the renal parenchyma and identification of anomalies of the urinary tract. These findings can be useful in choosing an optimal algorithm of diagnosis and surgical treatment of the disease.

This study was done to find answers for further following questions in cases of the collapsed gallbladder (GB) : What is the probability of the presence of stone when stony echo is visible in GB area? What is the probability of the presence of stone when only acoustic shadow is visible from GB area? What are the associated GB pathologies except stone or cholecystitis in previously mentioned situations and is it possible to differentiate them? What are the underlying pathologies of GB collapse without stony echo or acoustic shadow and is it possible to differentiate them sonographic ally? What are the rate and causes of re-expansion of the collapsed GB on follow-up study? Prospective study was done in 157 cases of collapsed GB with no visible or nearly no visible bile filled lumen in recent 3 years. Sonographic analysis for GB lesions was done in 61 confirmed cases. Changing pattern of GB lumen on follow-up study and their underlying pathologies were analyzed in 28 cases. Initial sonographic examination was done with 3 or 3.5 MHz transducer. No other transducer was used in cases showing stony echo or acoustic shadow in GB area, but additional examination was done with 5 or 7-4 MHz transducer in cases without stony echo or acoustic shadow. Among 31 cases, which showed stony echo, stone was found in 30 cases and milk of calcium bile in one case. Stone was present in all of the 11 cases which showed only acoustic shadow from the collapsed GB without stony echo. GB cancer was accompanied in 2 cases among upper 42 cases, and its possibility could be suspected sonographic ally. Underlying pathologies of the 19cases without stony echo or acoustic shadow were as follows : GB stone (3), cholecystitis (6), GB cancer (1), bile plug syndrome (1), hepatitis (5), and ascites (3). And sonographic differentiation of the underlying causes for the collapse was possible in only 1 case of GB cancer. Among 28 cases of the follow-up study, 20 cases showed re-expansion of the GB lumen and

Full Text Available Introduction:TORCH infections causing via Toxoplasma gondii, other microorganisms (e.g., Treponema pallidum, Rubella virus, Cytomegalovirus (CMV and the Herpes Simplex Virus (HSV types 1 and 2 during the first trimester of pregnancy can lead to severe fetal anomalies or even fetal loss. The current study determined the serological data of TORCH infections in women who were in their first trimesters of pregnancy.This descriptive study was carried out on 80 pregnant women in their first trimester in Kashan, Iran. Methods: To detect specific IgM antibodies and specific IgG antibodies against the TORCH infections via ELISA, Sera were collected from the pregnant women. Results: The specific IgG antibodies were found to be positive in 30(37.5% cases for toxoplasmosis, in 74 (92.5% cases for the Rubella virus, in 79(98.8% cases for CMV and in 73 samples (91.3% for the HSV types 1 and 2 infection. 3.8% of cases were found to be seropositive for Toxoplasma IgM antibody (95% CI, 0.38-7.9, 5% were positive for CMV IgM antibody (95% CI, 0.23-9.77 and 7.5% were positive for the HSV IgM antibody (95% CI, 1.8-13.2. 63.8% of pregnant women were at risk for at least to one of the TORCH agents. Conclusion: This study showed a high prevalence of infections caused by TORCH agents among pregnant women. Therefore, national screening programmed is necessary to screen the TORCH infections routinely and to prevent and treat congenital TORCH infection

2017-07-01

Gestational diabetes mellitus (GDM) is a form of diabetes that affects pregnant women. GDM tends to resolve after delivery, but has an impact on the health of the mother and her offspring. Considering the potential association between noise and diabetes and the susceptibility of the pregnant state to diabetogenesis, noise pollution may be associated with the risk of GDM; however, there is no evidence of the effect of noise pollution on GDM. In this study, we investigated the association between residential exposure to noise during the first trimester and incidence of GDM using the National Health Insurance Service-National Sample Cohort (NHIS-NSC), a representative sample of South Koreans. We analyzed the National Health Insurance Service-National Sample Cohort (2002-2013), a population-wide health insurance claim data. Study population was a total of 18 165 pregnant women. GDM was defined as ICD-10 code O244, and noise exposure levels were categorized as daytime (07:00-19:00) and nighttime (23:00-7:00). Other known risk factors for GDM were age, income, residential area, physical activity, smoking, drinking, blood sugar levels, and body mass index before getting pregnant. The study population included 18 165 pregnant women, of which 8.8% developed gestational diabetes. After adjustment, the adjusted OR (95% CI) for GDM associated with 1 dB increase in nighttime noise was 1.07 (95% CI: 1.05-1.10). Compared with the reference group (Quartile 1), the adjusted ORs for GDM in those exposed to the highest quartile of noise exposure (Quartile 4) was 1.61 (95% CI: 1.38-1.87) at nighttime noise. However, no significant association was observed between daytime noise exposure (07:00-19:00) and the incidence of GDM. We observed that the odds of gestational diabetes during the first trimester was 1.6 times higher for pregnant women exposed to elevated nighttime noise compared to similar women exposed to normal baseline noise levels in South Korea. Although this finding

Full Text Available Background and objective: Miscarriage represents a common problem that occurs in the first trimester of pregnancy. There is no general agreement on the value of submitting tissues from uterine evacuation in cases of miscarriage for histopathological examination. This study aimed to evaluate the role of histopathological examination in cases of first-trimester miscarriage. Methods: This is a descriptive study was carried out over a period of 14 months, from January 2015 to March 2016, at Erbil Maternity Hospital. A total of 375 biopsies from patients admitted to maternity hospital with the diagnosis of the first trimester miscarriage and cases of spontaneous miscarriage were included in this study. The clinical data including age, parity, gestational age, clinical diagnosis, the method of evacuation, and other relevant information were collected and submitted for histopathological examination. Results: Incomplete miscarriage was the commonest type of miscarriage and constituted 65.3% of the studied group and surgical evacuation was the most common method of termination. The histopathology reports confirmed the pregnancy in all patients and revealed retained product of normal pregnancy in 315 (86.6% cases, partial mole in 15 (4% patients, complete hydatidiform mole in one (0.2% case, decidual reaction in 21 (5.6% cases and no product of conception in 13 (3.4% cases. Conclusion: Histopathological examination of the products of conception is an important method in detecting undiagnosed molar pregnancy that needs special follow-up and further management.

To determine the need for routine third-trimester antibody screening in Rh+ women. An analytic case-control study. We identified Rh+ pregnant women who had received prenatal care and retrospectively analyzed their laboratory data. Patients were grouped into those with a positive third-trimester antibody screen (cases) and those with a negative third-trimester screen (controls). Because entry into a group was decided by the investigators, it could not be randomized. We reviewed the maternal medical records for antibody identification and final pregnancy outcome. We also reviewed the neonatal medical records for evidence of direct Coombs-positive cord blood, anemia, need for transfusion or phototherapy, other medical complications, and death. Using a computerized laboratory database from 2 teaching hospitals, we identified 10,581 obstetric patients who underwent routine first- and third-trimester antibody screening between 1988 and 1997. Of these, 1233 patients were Rh- and 9348 were Rh+. Among the Rh+ patients, 178 (1.9%) had 1 or more atypical antibodies at the first-trimester screen, and 53 (0.6%) had a positive third-trimester antibody screen despite a negative first-trimester screen. Although 6 of these 53 patients (0.06% of the study population) had clinically relevant antibodies for hemolytic disease of the new-born, no significant neonatal sequelae occurred among these 6 patients. Based on the patient and hospital records studied, a repeat third-trimester antibody screen for Rh+ patients is clinically and economically unjustified. Eliminating this laboratory test from clinical practice will not adversely affect pregnancy outcomes and will decrease the costs of prenatal care.

2013-09-01

The purpose of this study is to describe the sonographic appearance of lymphoma of the gastrointestinal tract in dogs. A retrospective review was conducted and patients with gastrointestinal lymphoma diagnosed by histopathology (including immunohistochemistry, where available) or cytology that had an abdominal ultrasound were included. Four of 15 (26·7%) cases with histopathologically confirmed lymphoma exhibited no sonographic abnormalities. In the dogs with sonographic abnormalities, features including intestinal wall thickness and the presence or absence of wall layering were highly variable. Clinical signs pertaining to the gastrointestinal tract were also unreliable markers of gastrointestinal lymphoma, with weight loss, vomiting, and diarrhoea being uncommon presenting complaints; intestinal obstruction was not present in any patient. The sonographic appearance of gastrointestinal lymphoma in dogs is non-specific. Gastrointestinal lymphoma in dogs should be maintained as a differential diagnosis despite a sonographically normal appearing bowel. © 2013 British Small Animal Veterinary Association.

Continuation of metformin in the first trimester of women with polycystic ovarian syndrome is not associated with increased perinatal morbidity.

Bolton, S

2012-02-01

This study aimed to assess the perinatal outcome, especially foetal growth, following the continuation of metformin during the first trimester of pregnancy. All women with polycystic ovary syndrome (PCOS) treated with metformin in the first trimester and who delivered a baby weighing 500 g or more between 2003 and 2005 were studied. Subjects were matched for age and parity with randomly selected controls. The perinatal outcomes studied were: growth parameters, gestational age, congenital defects, hypoglycaemia and neonatal unit admission. Sixty-six pregnancies were compared with 66 controls; all had singleton deliveries. There was no difference in mean birth weight between the metformin and the control groups (p=0.84). The percentage of small (<10th centile) and large (>90th centile) for gestational age babies was lower in the metformin group. In the metformin group, there were no major congenital malformations and 24% of the babies were admitted to the neonatal intensive care unit (NICU) compared with 27% of the babies in the control group (non-significant). Neonatal hypoglycaemia was less common in the metformin group (18.5% vs. 24.5%) and fewer babies required intravenous glucose therapy (6.3% vs. 12%). We found no evidence that the continuation of metformin in the first trimester of pregnancy was associated with an adverse foetal outcome.

To describe a new ultrasound technique that may be useful for the diagnosis of micrognathia in the first trimester of pregnancy. The retronasal triangle (RNT) view is a technique that captures the coronal plane of the face in which the primary palate and the frontal processes of the maxilla are visualized simultaneously. Normal first-trimester fetuses display a characteristic gap between the right and left body of the mandible in this view (the 'mandibular gap'). The presence or absence of this gap was evaluated and measured prospectively during real-time scanning (n = 154) and retrospectively by analyzing three-dimensional (3D) datasets (n = 50) in normal first-trimester fetuses undergoing screening for aneuploidy at 11-13 weeks' gestation. 3D datasets from 12 fetuses with suspected micrognathia were also collected and examined retrospectively for the same features. The mandibular gap was identified in all 204 normal fetuses and increased linearly with increasing crown-rump length (y = 0.033x + 0.435; R(2) = 0.316), with no statistically significant differences between measurements obtained by two-dimensional ultrasound and 3D offline analysis. Among fetuses with suspected micrognathia, three 3D datasets were excluded from analysis because of poor image quality in one and the diagnosis of a normal chin in two. In the remaining nine fetuses, the mandibular gap was absent and was replaced by a bony structure representing the receding chin in seven (77.8%) cases and was not visualized due to severe retrognathia in the remaining two (22.2%) cases. All fetuses with micrognathia had associated anomalies, including seven with aneuploidy and two with skeletal dysplasia. The RNT view may be a helpful technique for detecting micrognathia in the first trimester. The absence of the mandibular gap or failure to identify the mandible in this view is highly suggestive of micrognathia and should prompt a targeted ultrasound scan to assess for other anomalies.

Depression and anxiety in the antenatal period are of public health concern given potential adverse effects for both mother and infant. Both are under-researched in the first trimester of pregnancy, especially in Africa. We examine the prevalence of first trimester antenatal depression and anxiety in a cohort of South African women and investigate associated risk factors. Data were collected from 946 women (2014-2016) in the Soweto First 1000 Days Cohort, a prospective pregnancy cohort in Soweto, South Africa. Antenatal depression was assessed using the Edinburgh Postnatal Depression Scale with a score of ⩾13 indicating probable depression. Anxiety was assessed using the short form of the State-Trait Anxiety Index with a score ⩾12 indicating probable anxiety. Prevalence of antenatal depression was 27% [95% confidence interval (CI) 24.2-29.8] and anxiety 15.2% (95% CI 12.9-17.5). Factors associated with antenatal depression and anxiety were predominantly relationship- and family-centred. Women who perceived that their partner made life harder for them had three-fold increased odds for depression [(odds ratio (OR) 3.33 [2.28-4.85] P<0.001], whereas those with family stressors had almost double the odds for depression (OR 1.78 [1.22-2.59] P=0.003) and anxiety (OR 1.75 [1.44-2.69] P=0.0011). Antenatal depression and anxiety are common in the first trimester of pregnancy, and partner and family relationship stressors are central. Longitudinal analysis is needed to determine if this is a phase of adjustment to pregnancy or onset of persistent symptomology. Early intervention may have secondary preventative effects and should involve the partner and family.

A number of first-trimester prediction models addressing important obstetric outcomes have been published. However, most models have not been externally validated. External validation is essential before implementing a prediction model in clinical practice. The objective of this paper is to describe the design of a study to externally validate existing first trimester obstetric prediction models, based upon maternal characteristics and standard measurements (eg, blood pressure), for the risk of pre-eclampsia (PE), gestational diabetes mellitus (GDM), spontaneous preterm birth (PTB), small-for-gestational-age (SGA) infants, and large-for-gestational-age (LGA) infants among Dutch pregnant women (Expect Study I). The results of a pilot study on the feasibility and acceptability of the recruitment process and the comprehensibility of the Pregnancy Questionnaire 1 are also reported. A multicenter prospective cohort study was performed in The Netherlands between July 1, 2013 and December 31, 2015. First trimester obstetric prediction models were systematically selected from the literature. Predictor variables were measured by the Web-based Pregnancy Questionnaire 1 and pregnancy outcomes were established using the Postpartum Questionnaire 1 and medical records. Information about maternal health-related quality of life, costs, and satisfaction with Dutch obstetric care was collected from a subsample of women. A pilot study was carried out before the official start of inclusion. External validity of the models will be evaluated by assessing discrimination and calibration. Based on the pilot study, minor improvements were made to the recruitment process and online Pregnancy Questionnaire 1. The validation cohort consists of 2614 women. Data analysis of the external validation study is in progress. This study will offer insight into the generalizability of existing, non-invasive first trimester prediction models for various obstetric outcomes in a Dutch obstetric population

Full Text Available The cytotrophoblast (CTB cells of the human placenta have membrane receptors that bind certain cardiotonic steroids (CTS found in blood plasma. One of these, marinobufagenin, is a key factor in the etiology of preeclampsia. Herein, we used synthetic receptors (SR to study their effectiveness on the angiogenic profile of human first trimester CTB cells. The humanextravillous CTB cells (Sw.71 used in this study were derived from first trimester chorionic villus tissue. Culture media of CTB cells treated with ≥1 nM SR level revealed sFlt-1 (Soluble fms-like tyrosine kinase-1 was significantly increased while VEGF (vascular endothelial growth factor was significantly decreased in the culture media (* p < 0.05 for each The AT2 receptor (Angiotensin II receptor type 2 expression was significantly upregulated in ≥1 nM SR-treated CTB cells as compared to basal; however, the AT1 (Angiotensin II receptor, type 1 and VEGFR-1 (vascular endothelial growth factor receptor 1 receptor expression was significantly downregulated (* p < 0.05 for each. Our results show that the anti-proliferative and anti-angiogenic effects of SR on CTB cells are similar to the effects of CTS. The observed anti angiogenic activity of SR on CTB cells demonstrates that the functionalized-urea/thiourea molecules may be useful as potent inhibitors to prevent CTS-induced impairment of CTB cells.

Purpose: This study was performed to evaluate the accuracy of upper abdominal ultrasound (US) scanning performed by sonographers in a district general hospital, to identify potential areas of weakness and to make recommendations to improve the service. Materials and methods: Upper abdominal US examinations performed and reported by sonographers over a 4-week period were retrospectively reviewed. The accuracy of the imaging findings and reports were assessed against other imaging, surgical, histological or laboratory findings and against clinical outcome. Results: A heterogenous group of 104 patients were included in the study, 62 of whom had an US abnormality. Errors of scanning or interpretation were identified in 10 patients (9.6%) of whom five (4.8%) were felt to be potentially significant. Conclusions: The sonographers' accuracy in reporting upper abdominal US scans was 90%. However, on the basis of this study we have implemented specific recommendations to improve the quality of the service

The aim of this study was to assess the changes in the power Doppler sonographic findings in patients with oral cancer undergoing chemotherapy and radiotherapy. We performed US examinations on 187 cervical lymph nodes (71 metastatic and 116 reactive nodes) excised from 52 patients before and after preoperative therapy. On Power Doppler images, we calculated the vascular index (VI) and evaluated the vascular pattern. We also assessed the diagnostic power using receiver operating characteristic (ROC) curve analysis. Irradiation caused an increase of the VI and better visualization of the vessels within the lymph node in the reactive nodes; however, in the metastatic nodes, the VI was not significantly different between that before and after irradiation. When the reader observed the images before irradiation, the area under an ROC curve (Az values) observed by B-mode sonography were closely similar to those obtained by B-mode plus power Doppler sonography. With both images before and after irradiation, the Az value obtained by B-mode plus power Doppler sonography was higher than that by B-mode sonography alone. After irradiation, the enhanced Doppler signals contributed to a better visualization of the vessels and a better detection of any vascular abnormalities. (orig.)

Full Text Available Abstract Introduction Rupture of the distal musculotendinous junction of the medial head of the gastrocnemius, also known as "tennis leg", can be readily examined using a soft tissue ultrasound. Loss of muscle fiber continuity and the occurrence of bloody fluid accumulation can be observed using ultrasound with the patient in the prone position; however, some cases may have normal ultrasound findings in this conventional position.

During the third attempt, with the patient's calf muscles examined in an unconventional knee flexed position, sonographic findings resembling tennis leg were detected. Case presentation A 60-year-old man in good health visited our rehabilitation clinic complaining of left calf muscle pain. On suspicion of a ruptured left medial head gastrocnemius muscle, a soft tissue ultrasound examination was performed. An ultrasound examination revealed symmetrical findings of bilateral calf muscles without evidence of muscle rupture. A roentgenogram of the left lower limb did not reveal any bony lesions.

The aim of this study was to follow the course of the superior mesenteric artery (SMA) in first-trimester fetuses to predict the location of the small bowel. Its abnormal course aids in early detection of congenital diaphragmatic hernia (CDH) and assessment of the contents of omphalocele. The SMA can be easily identified in a sagittal section of the fetus by using color Doppler sonography at the 11- to 14-week scan, and normally, it has a downward course caudally to supply the intestines. The course of the SMA points to the location of the bowel. We report a series of 7 cases detected in first trimester with an abnormal course of the SMA, 3 of which had CDH and 4 of which had omphalocele. In CDH, the intestines herniate into the thoracic cavity; hence, the SMA tends to have an upward course toward the thorax. In 4 cases of omphalocele, the SMA follows the exteriorized bowel into the base of the umbilical cord. Second-trimester sonography for detection of congenital malformations is a standardized protocol, but a careful anatomic survey at the 11- to 14-week scan is often rewarding. When there is a suspicion of an intrathoracic mass or a mediastinal shift, the upturned course of SMA serves as a valuable sign in confirmation of CDH. Chromosomal abnormalities are often reported in cases of omphalocele containing small bowel only, and the upward course of the SMA toward the base of the cord helps in its early prenatal diagnosis, which facilitates early genetic assessment in these fetuses. © 2017 by the American Institute of Ultrasound in Medicine.

Objectives to assess the performance of a combined first-trimester screening for trisomy 21 in an unselected Italian population referred to a specialized private center for prenatal medicine. Methods a retrospective validation of first-trimester screening algorithms [risk calculation based on maternal age and nuchal translucency (NT) alone, maternal age and serum parameters (free β-hCG and PAPP-A) alone and a combination of both] for fetal aneuploidies evaluated in an unselected Italian population at Artemisia Fetal-Maternal Medical Centre in Rome. All measurements were performed between 11+0 and 13+6 weeks of gestation, between April 2007 and December 2008. Results of 3,610 single fetuses included in the study, we had a complete follow-up on 2,984. Fourteen of 17 cases of trisomy 21 were detected when a cut-off of 1:300 was applied [detection rate (DR) 82.4%, 95% confidence interval (CI) 64.2–100; false-positive rate (FPR) 4.7%, 95% CI 3.9–5.4; false-negative rate (FNR) 17.6%, 95% CI 0–35.8%]. Conclusion in our study population the detection rate for trisomy 21, using the combined risk calculation based on maternal age, fetal NT, maternal PAPP-A and free β-hCG levels, was superior to the application of either parameter alone. The algorithm has been validated for first trimester screening in the Italian population. PMID:26266002

Tocopherols were discovered for their role in animal reproduction, but little is known about the contribution of deficiencies of vitamin E to human pregnancy loss. We sought to determine whether higher first-trimester concentrations of α-tocopherol and γ-tocopherol were associated with reduced odds of miscarriage (pregnancy losses tocopherol (tocopherol (tocopherol distribution in women who did not miscarry). In all women, plasma α- and γ-tocopherol concentrations were low [median (IQR): 10.04 μmol/L (8.07-12.35 μmol/L) and 0.66 μmol/L (0.50-0.95 μmol/L), respectively]. In a logistic regression analysis that was adjusted for cholesterol and the other tocopherol, low α-tocopherol was associated with an OR of 1.83 (95% CI: 1.04, 3.20), whereas a low γ-tocopherol concentration was associated with an OR of 0.62 (95% CI: 0.41, 0.93) for miscarriage. Subgroup analyses revealed that opposing ORs were evident only in women with BMI (in kg/m(2)) ≥18.5 and serum ferritin concentration ≤150 μg/L, although low BMI and elevated ferritin conferred stronger risk of miscarriage. In pregnant women in rural Bangladesh, low plasma α-tocopherol was associated with increased risk of miscarriage, and low γ-tocopherol was associated with decreased risk of miscarriage. Maternal vitamin E status in the first trimester may influence risk of early pregnancy loss.

Full Text Available Bacterial vaginosis (BV in pregnancy is associated with the increase of adverse pregnancy outcomes such as premature rupture of membranes and preterm labor. One of the multifactorial causes of BV is thechange in vaginal immunity. Malnutrition, including micronutrient deficiency, increases the vulnerability toinfections. This study aim to investigate the association between folic acid and zinc concentration with theincidence of bacterial vaginosis in the first trimester of pregnancy. This descriptive cross sectional studyinvolved 139 mothers with first trimester pregnancy, aged between 17-39 years old. The study was conductedat dr. Cipto Mangunkusumo Hospital from September 2013 until August 2014. Vaginal secretions was sampledto diagnose BV under nugent criteria. Folic acid and zinc in the serum were measured. From 139 subject,18.7% (n=26 were found to be BV positive (nugent score =7. No deficiency of folic acid (<7 ng/mL and40.3% (n=56 of zinc deficiency (<60  µg/dL were found. Bivariate analysis used Kruskal-Wallis test betweenfolic acid and zinc concentration with BV incidence gives p value of 0.668 and 0.478 respectively. Prevalenceof BV in this study was 18.7%. The relation between the maternal statuses of folic acid with BV in the firsttrimester of pregnancy was not found.

Full Text Available Although a history of first-trimester recurrent spontaneous abortion (FRSA is regarded as a risk factor in antenatal care, the characteristic of subsequent pregnancy outcome is not clearly elucidated. Here, a retrospective analysis was performed on the clinical data of 492 singleton pregnant women. 164 of them with the history of FRSA were enrolled in study group, compared to 328 deliveries without the history of FRSA. For maternal outcomes, patients in the study group delivered earlier with mean gestational age and the incidences of cesarean section and postpartum hemorrhage were higher compared to the control group. For placental outcomes, the incidence of placenta-mediated pregnancy complications (PMPC in the study group increased in terms of late-onset preeclampsia, oligohydramnios, early-onset fetal growth restriction, and second-trimester abortion. Patients in the study group were more likely to suffer from placenta accreta, placenta increta, and placenta percreta. For perinatal outcomes, the proportion of birth defects of newborns in the study group was greater. At last, logistic regression analyses showed that the history of FRSA was an independent risk factor for cesarean section and pregnancy complications. In conclusion, women with the history of FRSA are often exposed to an elevated incidence of maternal-placental-perinatal adverse pregnancy outcomes.

Characterization of normal changes in the serum proteome during pregnancy may enhance understanding of maternal physiology and lead to the development of new gestational biomarkers. In 23 Nepalese pregnant women who delivered at term, two-dimensional difference in-gel electrophoresis (DIGE) was used to assess changes in relative protein abundance between paired serum samples collected in the first and third trimesters. One-hundred and forty-five of over 700 protein spots in DIGE gels (pI 4.2-6.8) exhibited nominally significant (p < 0.05) differences in abundance across trimesters. Additional filtering using a Bonferroni correction reduced the number of significant (p < 0.00019) spots to 61. Mass spectrometric analysis detected 38 proteins associated with gestational age, cytoskeletal remodeling, blood pressure regulation, lipid and nutrient transport, and inflammation. One new protein, pregnancy-specific β-glycoprotein 4 was detected. A follow-up isotope tagging for relative and absolute quantitation (iTRAQ) experiment of six mothers from the DIGE study revealed 111 proteins, of which 11 exhibited significant (p < 0.05) differences between trimesters. Four of these proteins: gelsolin, complement C1r subcomponent, α-1-acid glycoprotein, and α-1B-glycoprotein also changed in the DIGE analysis. Although not previously associated with normal pregnancy, gelsolin decreased in abundance by the third trimester (p < 0.01) in DIGE, iTRAQ and Western analyses. Changes in abundance of proteins in serum that are associated with syncytiotrophoblasts (gelsolin, pregnancy-specific β-1 glycoprotein 1 and β-2-glycoprotein I) probably reflect dynamics of a placental proteome shed into maternal circulation during pregnancy. Measurement of changes in the maternal serum proteome, when linked with birth outcomes, may yield biomarkers for tracking reproductive health in resource poor settings in future studies.

In the absence of aneuploidy or other pathogenic cytogenetic abnormality, fetuses with increased nuchal translucency (NT ≥ 3.5 mm) and/or other sonographic abnormalities have a greater incidence of genetic syndromes, but defining the underlying pathology can be challenging. Here, we investigate the value of whole exome sequencing in fetuses with sonographic abnormalities but normal microarray analysis. Whole exome sequencing was performed on DNA extracted from chorionic villi or amniocytes in 24 fetuses with unexplained ultrasound findings. In the first 14 cases sequencing was initially performed on fetal DNA only. For the remaining 10, the trio of fetus, mother and father was sequenced simultaneously. In 21% (5/24) cases, exome sequencing provided definitive diagnoses (Milroy disease, hypophosphatasia, achondrogenesis type 2, Freeman-Sheldon syndrome and Baraitser-Winter Syndrome). In a further case, a plausible diagnosis of orofaciodigital syndrome type 6 was made. In two others, a single mutation in an autosomal recessive gene was identified, but incomplete sequencing coverage precluded exclusion of the presence of a second mutation. Whole exome sequencing improves prenatal diagnosis in euploid fetuses with abnormal ultrasound scans. In order to expedite interpretation of results, trio sequencing should be employed, but interpretation can still be compromised by incomplete coverage of relevant genes. © 2015 John Wiley & Sons, Ltd.

The aim of this study was to determine the clinical characteristics and sonographic features of lymphadenopathy (LAP) and to evaluate the treatment modalities and treatment outcomes in children with tularemia. Demographic characteristics, ultrasonographic and physical examination findings, and treatment outcomes in 55 tularemia patients (24 male and 31 female) with a mean age of 10.8 ± 4.0 years were analyzed retrospectively. Lymph node necrosis was classified in three stages based on ultrasound findings-stage 1, cortical microabscesses; stage 2, cortical and medullar abscesses; stage 3, total necrosis of the lymph node. In total, 50 (90%) of the patients had oropharyngeal, four (8%) had glandular, and one (2%) had oculoglandular tularemia. The most common symptoms were sore throat (67%) and fever (64%). LAP was the most frequently (100%) observed sign. Abscess formation was noted in 36 (65%) patients, of which seven (19%) were sonographically classified as stage 1, 20 (55%) as stage 2, and nine (26%) as stage 3. There was a statistically significant correlation between delayed treatment and stage of abscess formation in lymph nodes (p0.05). In all, nine (16%) of the patients did not respond to medical treatment, and surgical intervention was required. Tularemia should be considered in the differential diagnosis of children presenting with unexplained fever, sore throat, and cervical LAP in endemic areas. Sonographic findings may be useful in the evaluation and staging of this infection.

Antigen-presenting cells represent targets for R5 HIV-1 infection in the first trimester pregnancy uterine mucosa.

Full Text Available BACKGROUND: During the first trimester of pregnancy, HIV-1 mother-to-child transmission is relatively rare despite the permissivity of placental cells to cell-to-cell HIV-1 infection. The placenta interacts directly with maternal uterine cells (decidual cells but the physiological role of the decidua in the control of HIV-1 transmission and whether decidua could be a source of infected cells is unknown. METHODOLOGY/PRINCIPAL FINDINGS: To answer to this question, decidual mononuclear cells were exposed to HIV-1 in vitro. Decidual cells were shown to be more susceptible to infection by an R5 HIV-1, as compared to an X4 HIV-1. Infected cells were identified by flow cytometry analysis. The results showed that CD14(+ cells were the main targets of HIV-1 infection in the decidua. These infected CD14(+ cells expressed DC-SIGN, CD11b, CD11c, the Fc gamma receptor CD16, CD32 and CD64, classical MHC class-I and class-II and maturation and activation molecules CD83, CD80 and CD86. The permissivity of decidual tissue was also evaluated by histoculture. Decidual tissue was not infected by X4 HIV-1 but was permissive to R5 HIV-1. Different profiles of infection were observed depending on tissue localization. CONCLUSIONS/SIGNIFICANCE: The presence of HIV-1 target cells in the decidua in vitro and the low rate of in utero mother-to-child transmission during the first trimester of pregnancy suggest that a natural control occurs in vivo limiting cell-to-cell infection of the placenta and consequently infection of the fetus.

The aim of the study was to analyze the sonographic features of nodular Hashimoto thyroiditis (HT) in patients with diffuse background thyroiditis and normal background thyroid parenchyma. Eighty-six patients who had fine-needle aspiration biopsy of 100 thyroid nodules confirmed to be HT and a thyroid ultrasound within 1 year of the biopsy were included in the study. Retrospective analysis of several sonographic features of each nodule was then performed. The mean age of patients with nodular HT was 53 years, 84% of which were female. Nodular HT occurred in a background of diffuse thyroiditis in 85% and in a homogeneous normal background in 15%. Ninety-three percent of nodules were completely solid and 7% of nodules were cystic and solid. Although the sonographic appearance of nodular HT was variable, the most common appearance was a solid (93/100) and hypoechoic nodule (44/100) with a thin hypoechoic halo (42/100) without calcifications (96/100). On color Doppler, 17% of nodules showed peripheral hypervascularity, 14% of nodules were diffusely hypervascular, 34% were iso vascular, 32% were hypovascular, and 3% were avascular. The sonographic appearance of nodular HT was not significantly different in patients with diffuse background thyroiditis compared with those without background thyroiditis. The sonographic appearance of nodular HT is variable, but the most common appearance is a solid sharply circumscribed hypoechoic nodule with thin hypoechoic halo without calcification. There was no significant difference in the appearance of nodular HT in patients with diffuse background thyroiditis compared with patients with normal background thyroid parenchyma.

2014-09-01

New early first-trimester diagnostic criteria for nonviable pregnancy recommended by the Society of Radiologists in Ultrasound via a multispecialty consensus panel extended the diagnostic size criteria of crown-rump length from 5 to 7 mm for embryos without a heartbeat and mean sac diameter from 16 to 25 mm for "empty" sacs. Our study assessed the potential impact of the new criteria on the number of additional follow-up sonograms these changes would engender. A retrospective study of all first-trimester sonograms in women with first trimester bleeding from 1999 to 2008 was conducted. Everyone included in the study had a visible gestational sac in the uterus. There were no pregnancies of unknown location or ectopic pregnancies included in this study cohort. Pregnancy of unknown location was used to describe cases in which there were no signs of pregnancy inside or outside the uterus on transvaginal sonography despite a positive pregnancy test result. A total of 1013 patients met the inclusion criteria. Seven hundred fifty-two patients (74%) had identifiable embryos, and 261 (26%) did not. Of those with an identifiable embryo, 286 (38%) had no detectable embryonic cardiac activity. The breakdown of crown-rump lengths in this group was as follows: 100 measuring less than 5 mm, 36 measuring 5 to 7 mm, and 150 measuring 7 mm or greater. The breakdown of mean sac diameters in those without a visible embryo was as follows: 120 measuring less than 16 mm, 90 measuring 16 to 25 mm, and 51 measuring 25 mm or greater. When diagnosing a failed pregnancy, there can be no room for error. Only 126 of 1013 early pregnancies threatening to abort (12%) fell into the more conservative zones defined by the new compared to the former size criteria (crown-rump length, 5-7 mm; mean sac diameter, 16-25 mm). Therefore, the potential impact of the new guidelines on follow-up sonograms does not appear inordinate. © 2014 by the American Institute of Ultrasound in Medicine.

Second trimester abortions in India.

Dalvie, Suchitra S

2008-05-01

This article gives an overview of what is known about second trimester abortions in India, including the reasons why women seek abortions in the second trimester, the influence of abortion law and policy, surgical and medical methods used, both safe and unsafe, availability of services, requirements for second trimester service delivery, and barriers women experience in accessing second trimester services. Based on personal experiences and personal communications from other doctors since 1993, when I began working as an abortion provider, the practical realities of second trimester abortion and case histories of women seeking second trimester abortion are also described. Recommendations include expanding the cadre of service providers to non-allopathic clinicians and trained nurses, introducing second trimester medical abortion into the public health system, replacing ethacridine lactate with mifepristone-misoprostol, values clarification among providers to challenge stigma and poor treatment of women seeking second trimester abortion, and raising awareness that abortion is legal in the second trimester and is mostly not requested for reasons of sex selection.

Full Text Available Background: Reactive oxygen species (ROS are produced in many metabolic and physiologic processes. Antioxidative mechanisms remove these harmful species. Our aim was to assess whether serum total antioxidant capacity and total oxidant status altered during first trimester pregnancies with vaginal bleeding. Materials and Methods: In this cross-sectional study, A group of pregnant women at less than 10 weeks of gestation with vaginal bleeding (n=25 and a control group of healthy pregnancies with similar characteristics (n=25 were included. All of the patients in the two groups were matched for age, gestational age and body mass index. Serum total antioxidant capacity and total oxidant status levels were determined using a Hitachi 912 analyzer and compared between the two groups. Results: Characteristics, including maternal age, parity, and gestational age were similar between the two groups. Serum total antioxidant capacity levels were significantly lower in the women with vaginal bleeding than in control women (1.16 ± 0.20 vs. 1.77 ± 0.08 mmol Trolox Equiv./L; p=0.001, whereas higher total oxidant status measurements were found in women with vaginal bleeding compared to the control group (4.01 ± 0.20 vs. 2.57 ± 0.65 μmol H2O2 Equiv./L; p=0.001. Conclusion: Increased total oxidant status might be involved in the pathophysiology of vaginal bleeding during early first trimester pregnancies.

Full Text Available Background. Placenta accreta is a potentially life-threatening obstetrical condition and is responsible for many emergency Caesarean hysterectomies. Early prenatal diagnosis may help minimize maternal morbidity and mortality. This report highlights risk factors, early diagnostic findings and complications associated with placenta accreta, and the role of first trimester sonography in diagnosis. Case. A 38-year-old pregnant woman, G2P1L1 with history of one previous Caesarean section, presented with vaginal bleeding at 13 weeks’ gestation. Ultrasound examination was highly suspicious of placenta previa with accreta. During an earlier 12-week scan for nuchal translucency measurement, the placenta was suboptimally visualized. She was counselled regarding potential maternal and fetal complications as well as management options. At 33 weeks’ gestation Caesarean hysterectomy was performed due to vaginal bleeding. Conclusion. Early ultrasound screening in high-risk patients may be advantageous in order to identify placenta accreta and conduct appropriate patient counseling regarding risks and management options.

The purpose of this study was to evaluate the associations of the first, second and third trimester serum pregnancy-associated plasma protein A (PAPP-A) concentrations with neonatal anthropometric parameters. The effect of tobacco smoking during pregnancy on PAPP-A level was also studied. One hundred and fifty healthy pregnant women were divided into smoking and tobacco-abstinent groups. Serum PAPP-A level was measured with the KRYPTOR rapid random-access immunoassay analyzer. The relationship between PAPP-A and newborn related outcome as well as markers of estimated intensity of cigarette smoking was evaluated by univariate and multivariate linear regression. Pregnancy-associated plasma protein A concentration was positively correlated with birth weight in the first (β = 31.6; p < 0.001), second (β = 10.6; p < 0.05), and third (β = 4.6; p < 0.001) trimester of gestation. A significant association between PAPP-A and birth body length and head circumference in the second (β = 0.02; p < 0.05) and third trimester (β = 0.01; p < 0.01) was also found. The serum PAPP-A levels were significantly lower in the smoking than in the tobacco-abstinent group in each trimester of pregnancy ( p < 0.001). The largest impact of the number of cigarettes smoked per day on PAPP-A level was found in the second (β = -1.2; p = 0.004) and third trimester (β = -2.6; p = 0.001). Maternal serum PAPP-A levels during gestation might be significant predictors for birth weight. Increased PAPP-A concentrations in the second and third trimester appeared to also be predictive for newborn body length and head circumference. Smoking alters maternal PAPP-A levels in all trimesters, with the greatest impact related to the number of cigarettes smoked per day.

Full Text Available Objective. The guidelines of the American Thyroid Association (ATA recommend an upper limit reference interval (RI of thyroid stimulating hormone (TSH of 2.5 mIU/L in the first trimester of pregnancy and 3.0 mIU/L in subsequent trimesters, but some reported ranges in China are significantly higher. Our study aimed to establish trimester- and assay-specific RIs for thyroid hormones in normal pregnant Chinese women. Methods. In this cross-sectional study, 2540 women with normal pregnancies (first trimester, n=398; second trimester, n=797; third trimester, n=1345 and 237 healthy nonpregnant control subjects were recruited. Serum TSH, free thyroxin (FT4, thyroid peroxidase antibody (TPOAb, and thyroglobulin antibody (TgAb levels were determined by automated chemiluminescence with an Immulite 2000 system (Siemens, Erlangen, Germany. After outliers were excluded, the 2.5–97.5th percentiles were used to define the RIs. Results. The RIs of thyroid function in the first, second, and third trimesters of pregnancy and in nonpregnant controls were 0.07–3.96, 0.27–4.53, 0.48–5.40, and 0.69–5.78 mIU/L for TSH and 9.16–18.12, 8.67–16.21, 7.80–13.90, and 8.24–16.61 pmol/L for FT4, respectively. Conclusion. The trimester- and assay-specific RIs of thyroid function during pregnancy differed between trimesters, which suggests that it is advisable to detect and avoid misclassification of thyroid dysfunction during pregnancy for women in Henan, China.

Portal venous gas suggests underlying bowel disease such as strangulating intestinal obstruction and its demonstration carries with it an important implications with respect to patient management. Radiography has been the gold standard for the detection of portal venous gas. We have experienced two cases of portal venous gas diagnosed by ultrasound. Sonographic findings were floating echoes in the main portal vein and highly echogenic linear or patchy echoes within the hepatic parenchyma. Simple abdominal films of those cases failed to demonstrate gas in the portal venous system

Juvenile fibroadenoma is an uncommon histologic variant of fibroadenoma that frequently shows a remarkable and rapid growth. The development of a carcinoma within a fibroadenoma, either in situ or invasive, is a rare condition. We encountered a 36-year-old woman with a palpable mass in the right breast. The radiologic findings were indicative of a fibroadenoma in the breast. Sonographic guided biopsy using a 14G core needle revealed the presence of ductal carcinoma in situ (DCIS) within the juvenile fibroadenoma. Focal excision was performed and the patient underwent radiation therapy in the right breast after surgery

The aim of this study was to describe a new sonographic sign of bone fracture and to determine if it can be helpful in decreasing the number of missed fractures of the proximal humerus. Ultrasound (US) of the shoulder was performed in 57 consecutive patients with shoulder pain and/or disability following trauma. All cases were prospectively reviewed for the presence of a humeral fracture. Sonographic signs of fractures, with special emphasis on what was termed the 'double line sign' (DLS), were assessed. Plain radiography was considered the standard of reference and in equivocal cases magnetic resonance imaging (MRI). Twenty-eight patients had a tuberosity complex fracture, which were all detected at US examination. Sonographic features of a fracture were periosteal elevation, corticol bone discontinuity, step-off deformity or a combination of these findings. This study showed that in 26 (93%) patients an additional sonographic feature, a DLS, could be demonstrated. The DLS is a helpful and probably reliable sonographic sign to indicate a humeral fracture. High-spatial-resolution US substantially increases the detection of fractures of the proximal humerus and should be considered as an alternative diagnostic tool prior to computed tomography (CT), MRI and arthroscopy in patients with persisting shoulder pain and/or disability following trauma.

2017-01-01

Full Text Available Background. The detection of a morbidly adherent placenta (MAP in the first trimester is rare. Risk factors such as multiparity, advanced maternal age, prior cesarean delivery, prior myomectomy, placenta previa, or previous uterine evacuation place patients at a higher risk for having abnormal placental implantation. If these patients have a first trimester missed abortion and fail medical management, it is important that providers have a heightened suspicion for a MAP. Case. A 24-year-old G4P3003 with 3 prior cesarean deliveries underwent multiple rounds of failed medical management for a missed abortion. She had a dilation and curettage that was complicated by a significant hemorrhage and ultimately required an urgent hysterectomy. Conclusion. When patients fail medical management for a missed abortion, providers need to assess the patient’s risk factors for a MAP. If risk factors are present, a series of specific evaluations should be triggered to rule out a MAP and help further guide management. Early diagnosis of a MAP allows providers to coordinate a multidisciplinary treatment approach and thoroughly counsel patients. Ensuring adequate resources and personnel at a tertiary hospital is essential to provide the highest quality of care and improve outcomes.

Full Text Available Objectives : Examination of pregnant women in the first trimester with transvaginal ultrasonography with the aim to study various fetal development markers, e.g., gestation sac, yolk sac, fetal heart motion, CRL length, and fetal anatomy in both normal and abnormal pregnancies. Comparative evaluation of transvaginal ultrasonography vis-ΰ-vis transabdominal scanning in the study of first trimester of pregnancy and its complications. To assess the relative merits and demerits of transvaginal ultrasonography in comparison with the transabdominal technique. Materials and Methods : The study will be conducted on 50 females patients during the first trimester of pregnancy. The study population will consist of both normal and abnormal pregnancies. These patients will be included on the basis of suspicion of or proven pregnancy of duration up to 12 weeks from LMP. The evaluation of the patients will include the following: Record of patients obstetrical history and clinical examination, record of pregnancy test and relevant investigations, ultrasonic examination of pregnancy. (a Transabdominal ultrasound scanning will be done with moderately distended bladder by using real time scanners with low frequency probe (3/3.5 MHz; (b transvaginal sonography will be done with the real-time sector scanner using high-frequency endovaginal probe (5/7.5 MHz, after the patient voids urine. Relevant images will be taken by using the multiformat automatic camera. Results and Conclusions : In the study of 46 normal intrauterine pregnancies, TVS showed additional information in 36 patients (78.3% as compared to TAS, in detection of gestation sac, yolk sac, double bleb sign, or better visualization of embryonic anatomy. In the abnormal pregnancy (n=17, TVS provided more information in 11 cases (64.9%, which included detection of embryonic demise, yolk sac, double bleb sign, or subchorionic hemorrhage. Regarding ectopic gestations (n=7, TVS gave additional information in 5

We present a case report of a foetus with Prune-Belly syndrome (PBS) which was diagnosed sonographically during the 13th week of gestation and review of the literature. Sonographic diagnosis was based on abnormally distended urinary bladder and abdomen and absence of 'keyhole sign'. Termination was performed on parental request and post-mortem examination revealed absence of abdominal wall musculature and the distended urinary bladder in a male foetus. Prenatal diagnosis of PBS is based on ultrasound and is usually diagnosed in the second trimester. In the first trimester there are very few reports to date. Prognosis and possible treatment options are herein discussed as well as the underlying mechanisms that may explain the clinical presentation of the syndrome.

Full Text Available Objectives: The biochemical serum markers free β-human chorionic gonadotropin (hCGβ and pregnancy associated plasma protein A (PAPP-A, used in screening for trisomy 21 (T21, trisomy 18 (T18, and trisomy 13 (T13 during the first trimester, can be measured on different laboratory instruments e.g. Kryptor (Brahms and Cobas (Roche. We compared the performance of these two analytical instruments when used for first trimester combined testing. Design and methods: Serum samples from 944 singleton pregnant women attending for first trimester combined testing were routinely assayed for hCGβ and PAPP-A on Kryptor, and re-analyzed on Cobas. In addition, serum samples from 70 pregnant women carrying a fetus affected by T21, T18 or T13, were re-assayed on Cobas. Results: For the screening population, the hCGβ and PAPP-A results in multiples of the median (MoM from Kryptor and Cobas were significantly lower on Cobas when compared to Kryptor. The number of pregnant women with a risk above 1:300 for T21 was 48 for both Cobas and Kryptor, although a few patients only had a high risk with one of the methods. Overall, the screen positive rate was 5.1% for both instruments. In the trisomy groups the calculated risks for T21, T18, and T13 agreed well between Cobas and Kryptor. Conclusions: The screen positive rate for T21 (5.1% did not differ between the two analytical platforms in our screening population, although PAPP-A measurements form Cobas were significantly lower than those from Kryptor. The calculated risks for the pregnancies affected by trisomies using hCGβ MoM and PAPP-A MoM from Kryptor agreed well with those from Cobas.

To determine whether sonographic versions of physical examination techniques can accurately identify splenomegaly, Castell's method (Ann Intern Med 1967; 67:1265-1267), the sonographic Castell's method, spleen tip palpation, and the sonographic spleen tip technique were compared with reference measurements. Two clinicians trained in bedside sonography patients recruited from an urban hematology clinic. Each patient was examined for splenomegaly using conventional percussion and palpation techniques (Castell's method and spleen tip palpation, respectively), as well as the sonographic versions of these maneuvers (sonographic Castell's method and sonographic spleen tip technique). Results were compared with a reference standard based on professional sonographer measurements. The sonographic Castell's method had greater sensitivity (91.7% [95% confidence interval, 61.5% to 99.8%]) than the traditional Castell's method (83.3% [95% confidence interval, 51.6% to 97.9%]) but took longer to perform [mean ± SD, 28.8 ± 18.6 versus 18.8 ± 8.1 seconds; P = .01). Palpable and positive sonographic spleen tip results were both 100% specific, but the sonographic spleen tip method was more sensitive (58.3% [95% confidence interval, 27.7% to 84.8%] versus 33.3% [95% confidence interval, 9.9% to 65.1%]). Sonographic versions of traditional physical examination maneuvers have greater diagnostic accuracy than the physical examination maneuvers from which they are derived but may take longer to perform. We recommend a combination of traditional physical examination and sonographic techniques when evaluating for splenomegaly at the bedside. © 2017 by the American Institute of Ultrasound in Medicine.

Full Text Available OBJECTIVES: Evaluate the feasibility of transvaginal uterine artery Doppler examination in the first and second trimesters of pregnancy, establish reference ranges in a Brazilian population and examine the correlation between these Doppler findings. METHODS: Longitudinal prospective study at the antenatal clinic of a tertiary teaching hospital. Uterine artery Doppler examinations were carried out transvaginally at 11 to 14 weeks and 20 to 25 weeks of gestation. Uterine artery mean pulsatility index (PI distributions were determined and the presence or absence of an early diastolic notch was also noted. The degree of correlation between first and second trimester Doppler findings was examined. RESULTS: Three hundred and forty four women with live singleton pregnancies and normal outcome were first examined at a mean gestation of 12.7 weeks. The values corresponding to the 50th and 95th centiles of mean PI were 1.69 and 2.48. Bilateral notches were observed in 44% of cases and unilateral notches were present in 19%. Second trimester Doppler examinations were carried out at a mean gestation of 23.2 weeks and corresponding figures for the 50th and 95th centiles were 1.03 and 1.57. Bilateral notches were noted in 4.4% of the cases. First trimester impedance indices were significantly higher and positively correlated to second trimester findings (r = 0.42, pOBJETIVO: Avaliar a aplicabilidade de realizar exames dopplervelocimétricos endovaginais das artérias uterinas no primeiro e segundo trimestres da gestação, definir valores normais na população brasileira e examinar a correlação entre esses achados.

The aim of this study was to discriminate mole pregnancies and invasive forms among cases with first trimester vaginal bleeding by the utilization of some complete blood count parameters conjunct to sonographic findings and beta human chorionic gonadotropin concentration. Consecutive 257 cases with histopathologically confirmed mole pregnancies and 199 women without mole pregnancy presented with first trimester vaginal bleeding who admitted to Zeynep Kamil Women and Children's Health Training Hospital between January 2012 and January 2016 were included in this cross-sectional study. The serum beta HCG level at presentation, and beta hCG levels at 1st, 2nd and 3rd weeks of postevacuation with some parameters of complete blood count were utilized to discriminate cases with molar pregnancy and cases with invasive mole among first trimester pregnants presented with vaginal bleeding and abnormal sonographic findings. Levels of beta hCG at baseline (AUC = 0.700, p < 0.05) and 1st (AUC = 0.704, p < 0.05), 2nd (AUC = 0.870, p < 0.001) and 3rd (AUC = 0.916, p < 0.001) weeks of postevacuation period were significant predictors for the cases with persistent disease. While area under curve for mean platelet volume is 0.715, it means that mean platelet volume has 21.5% additional diagnostic value for predicting persistency in molar patients. For 8.55 cut-off point for mean platelet volume, sensitivity is 84.6% and specificity is 51.6%. Area under curve for platelet/lymphocyte ratio is 0.683 means that platelet/lymphocyte ratio has additional 18.3% diagnostic value. For 102.25 cut-off point sensitivity is 86.6% and specificity is 46.2. Simple, widely available complete blood count parameters may be used as an adjunct to other risk factors to diagnose molar pregnancies and predict postevacuation trophoblastic disease.

Risk factors for failed first-trimester surgical abortion include endometrial distortion caused by leiomyomas, uterine anomalies and malposition and cervical stenosis. This report introduces intrauterine adhesions as an additional risk factor. A multiparous woman presented for pregnancy termination at 6 weeks' gestation. Three suction-curettage attempts failed to remove what appeared to be an intrauterine pregnancy. Rising beta-hCG levels and concern for an interstitial ectopic pregnancy prompted a diagnostic laparoscopy and exploratory laparotomy without the identification of an ectopic pregnancy. After methotrexate treatment failed, the patient underwent ultrasound-guided hysteroscopy and suction curettage using a cannula with a whistle-cut aperture for the successful removal of a pregnancy implanted behind intrauterine adhesions. Intrauterine adhesions are a cause of failed surgical abortion. Ultrasound-guided hysteroscopy may be required for diagnosis.

Ultrasonography is the most valuable diagnostic tool in the evaluation of gallbladder (GB) diseases. Although sonographic findings in GB cancer have been well described, the diagnostic accuracy has not been clearly analyzed. Our purpose of this report was to discuss diagnostic difficulties and analyze causes of misdiagnosis of GB cancer based on our recent experience and so may result in more accurate diagnosis of GB cancer. We analyzed 13misdiagnosed cases out of 24 cases of GB cancer with special emphasis on diagnostic difficulties and causes of misidagnosis. The most common type of misdiagnosed GB cancer was thickened wall type which was found in 10 cases. Preoperative sonographic diagnosis of these cases was empyema in 4 cases, cholecystitis in 3, and non-specific GB wall thickening in 1. In 2 cases, any lesion could not be detected at ultrasonography. Two cases with intraluminal type of GB cancer were misdiagnosed ; one being misdiagnosed as cholecystitis with stone, and the other being completely missed. Three cases that were completely missed consist of 2 with focal wall thickening and 1 involving GB neck. In conclusion, sonographic diagnosis of GB cancer is difficult, because the wall thickening type, that mimicks the cholecystitis, is frequent. Thorough and careful investigation of GB is mandatory for eliminating misdiagnosis

The purposes of our study were to find out characteristic ultrasonographic findings of gynecomastia and to analyze age distribution, causative factors of gynecomastia. For these purposes, medical records of 39 male patients with gynecomastia were reviewed and sonographic findings of 13 cases of gentamycin were analyzed. Gynecomastia was found most commonly in teenagers and commonly in twenties. Almostly, it occurred without any evident etiology and classified as idiopathic or pirbuterol type. Less frequently, it occurred due to drug administration, systemic disease, or male hormone deficiency. Unilateral involvement was seen in 29 cases; 17cases involving the left and 12 cases the right. Bilateral involvement was seen in 10 cases. Sonographically,gynecomastia appeared as hypoechoic or intermediate echoic mass with various shape in the subareolar area. One case showed diffuse fatty breast pattern without definable mass. On sonographic evaluation, prominent nipple should not be misinterpreted as a breast mass. For the correct diagnosis of gynecomastia, both side breasts should be evaluated for comparison

We previously reported an increased prevalence of any congenital malformation among women experiencing moderate-to-severe asthma exacerbations during the first trimester of pregnancy, based on a study in which 90.1% of the cohort of women were social welfare recipients. This study re-examined the association between asthma exacerbations and congenital malformations in a new large representative cohort of asthmatic pregnant women. A cohort of 36 587 pregnancies in asthmatic women was reconstructed from Québec Province administrative databases (1998-2009). Occurrences of asthma exacerbations during the first trimester of pregnancy were assessed and categorised into severe, moderate and no such exacerbations. For comparison, we also considered moderate and severe asthma exacerbations combined. Congenital malformations were identified using diagnoses recorded in the hospitalisation database. Generalised estimation equations were used to estimate adjusted ORs of congenital malformations. The prevalence of any congenital malformation was 19.1%, 11.7% and 12.0% among women with severe, moderate and no such exacerbations during the first trimester, respectively. The adjusted OR for all malformations was 1.64 (95% CI 1.02 to 2.64) when women with severe exacerbations were compared with those in the reference group, while no association was seen for moderate exacerbations. Also, no association was observed between cases of moderate and severe asthma exacerbations combined and any congenital malformation. Only severe asthma exacerbations were found to significantly increase the risk of congenital malformations in this representative study. Previous studies possibly overestimated the risk because they were based mainly on women at a lower socioeconomic status. Published by the BMJ Publishing Group Limited.

To establish a structured review process to facilitate the identification of the fetal nasal bone (NB) in the first trimester ultrasound scan to improve the quality images. We conducted a retrospective observational study in fetal NB images obtained during ultrasound exams of singleton pregnancies that underwent first trimester screening (crown-rump length 45-84 mm). When the images were obtained the examiner was not aware of the study. Audit was conducted by an examiner according criteria established by the Fetal Medicine Foundation. Fetal NB images were assessed regarding adequate magnification, mid-sagittal view and transducer held parallel to the direction of the nose. The transvaginal and transabdominal as well as anterior and posterior fetal back groups were compared using χ(2) test. We considered 874 fetal NB images for auditing. Fetal NB was considered present in 865 images (99%). During the audit process, we identified 72 (8.2%) cases of disagreement between examiner and auditor assessments. Disagreement was higher when image quality was poor (62 cases = 7%). Transvaginal approach performed better in the following criteria: adequate magnification (p audit program for fetal NB is feasible in a clinical scenario. Image quality appears to play an important role in compliance to image standards audited and in agreement between examiner and auditor.

Sonographic demonstration of stomach pathology: Reviewing the cases

Science.gov (United States)

2015-01-01

Abstract Introduction: The stomach can be the source of complaints for many patients attending for upper abdominal ultrasound. It is not routinely imaged as part of most upper abdominal ultrasound protocols, with sonographers and sonologists alike commonly muttering the line; “I can't see the stomach on ultrasound”. However, this is incorrect, as the gastric antrum can almost always be visualised sonographically. Discussion: It is possible to detect a range of pathologies affecting the stomach sonographically, from common, largely tolerable conditions such as hiatus hernias through to life‐threatening neoplasms. Conclusion: The stomach can easily be assessed during routine abdominal ultrasound providing the sonographer has knowledge of stomach anatomy, normal ultrasound appearances and limitations to its visualisation. While endoscopy is the gold standard for investigation of the stomach and upper gastrointestinal tract, many patients will initially present for abdominal ultrasound due to its easy, non‐invasive nature, ready availability and low cost. For patients with mild abdominal symptoms, a normal abdominal ultrasound may be the extent of their imaging investigations meaning stomach pathologies may go undiagnosed. PMID:28191199

To assess different bacterial and epidemiological factors associations with increased vaginal pH in the pregnant women population during the first trimester. A cross-sectional, observational study. Three outpatient clinics in Riga. From July 2009 until January 2010, 139 unselected consecutive pregnant women at the first prenatal visit. Pregnant women were submitted to an interview, vaginal examination and vaginal specimen collection for pH measurement and native microscopy. Vaginal pH ≥4.5 was considered as elevated. Abnormal bacterial microflora was classified according to Donders. Elevated vaginal pH was significantly associated with bacterial vaginosis (p aerobic vaginitis (p aerobic vaginitis and bacterial vaginosis flora (p vaginal flora. Normal lactobacillary morphotypes were more often found in the pH ≤4.4 group (p vaginal pH is associated with different types of abnormal vaginal flora and the presence of sperm cells. © 2010 The Authors Acta Obstetricia et Gynecologica Scandinavica© 2010 Nordic Federation of Societies of Obstetrics and Gynecology.

To find out the sonographic findings that are useful to differentiate hepatic abscess from peripheral cholangiocarcinoma. Twenty-two hepatic abscesses and 22 peripheral cholangiocarcinomas which had been confirmed histologically were included in this study. Objective points were echo characteristics of the lesion, internal septation, presence of peripheral low echoic rim, demarcation from normal liver(well or poorly defined), posterior enhancement, multiplicity, dilatation of bile duct(obstructive or non-obstructive), intrahepatic duct stone, pleural effusion, and intra-abdominal fluid collection. Echo characteristics of the lesion were classified in-to four types. Type I; Predominantly echogenic with hypoechoic portion, type II; Echogenic without hypoechoic portion, type III; Predominantly hypoechoic with echogenic portion, type IV; Hypoechoic without echogenic portion. 1)Nine abscesses and 2 peripheral cholangiocarcinomas were type I(p=0.037), 2)One abscess and 18 peripheral cholangiocarcinomas were type II(p=0.001), 3)Seven abscesses and none of peripheral cholangiocarcinomas were type III(p=0.001), 4)Five abscesses and 2 peripheral cholangiocarcinomas were type IV(p=0.410). Only 7 abscesses showed internal septations(p=0.013). One abscess and 9 peripheral cholangiocarcinomas showed peripheral hypoechoic halos(p=0.012). Only 9 peripheral cholangiocarcinomas showed obstructive bile duct dilatation (p=0.001). There were no statistically significant differences between abscess and peripheral cholangiocarcinoma on other objective points. Predominantly echogenic with hypoechoic portion, predominantly hypoechoic with echogenic portion, and internal septation are the features suggestive of hepatic abscess, and echogenic without hypoechoic portion, peripheral hypoechoic halo, obstructive bile duct dilatation are suggestive of peripheral cholangiocarcinoma. Therefore these sonographic findings are helpful to differentiate hepatic abscess from peripheral

Epithelial cells lining the vagina are major components of genital tract immunity. The influence of the vaginal microbiome on properties of host epithelial cells is largely unexplored. We evaluated whether differences in the most abundant lactobacilli species or bacterial genera in the vagina of first trimester pregnant women were associated with variations in the extent of stress and autophagy in vaginal epithelial cells. Vaginal swabs from 154 first trimester pregnant women were analyzed for bacterial composition by amplification and sequencing of the V1-V3 region of bacterial 16S rRNA genes. Vaginal epithelial cells were lysed and autophagy quantitated by measurement of p62. Intracellular levels of the inducible 70kDa heat shock protein (hsp70), an indicator of cell stress and an autophagy inhibitor, were determined. When Lactobacillus crispatus was the most abundant member of the vaginal microbiota, epithelial p62 and hsp70 levels were lowest as compared to when other bacterial taxa were most abundant. The highest concentrations of p62 and hsp70 were associated with Streptococcus and Bifidobacterium abundance. The p62 level associated with Gardnerella abundance was lower than that observed when lactobacilli other than L. crispatus were most abundant. In conclusion, in the first trimester of pregnancy the abundance of different bacterial taxa is associated with variations in autophagy and magnitude of the stress response in vaginal epithelial cells.

Tubular adenoma (TA) is known as a rare lesion of the breast which is difficult to diagnosis preoperatively because of its rarity and similarity to fibroadenoma. Hence, our purpose is to suggest the characteristic sonographic features for its correct diagnosis. We retrospectively analyzed the clinical data and mammographic and sonographic findings. of seven patients(mean age, 23) who during the previous five years had presented at our hospital with pathologically-proven tubular adenoma. TA was misdiagnosed as fibroadenoma, since on physical examination of these young females, the lesions presented a palpable, non-tender mass. Mammographically, they showed a well defined mass similar to fibroadenoma. However, sonographic findings were characteristic of TA and compared to fibroadenoma, showed a well demarcated and smooth bordered mass with transverse long axis, posterior enhancement and homogeneous lower internal echogenecity. No case showed lateral wall refractive shadowing. In young females, the clinical and mammographic findings of TA are similar to those of fibroadenoma. However, sonographic findings of TA can, be helpful in the differential diagnosis of this entity and fibroadenoma.

Full Text Available Background and Objectives: several investigations have been done to evaluate the effect of Ramadan fasting on fetal and maternal health, which have all led to controversial results. The role of Ramadan fasting time in birth weight is still unclear. This study evaluated the effect of fasting at different periods of pregnancy on birth weight. Methods: 250 pregnant women fasting at least one day during Ramadan participated in this retrospective cohort study. Subjects were categorized into 3 groups, namely first trimester (n=112, second trimester (n=68 and third trimester (n=70 of pregnancy. Demographic and anthropometric data, obstetric history and history of Ramadan fasting were recorded. After delivery, neonatal birth weight was measured. The mean of weight and frequency of low birth weight in each group were calculated. Probable related factors of low birth weight of neonates with fasting mothers were evaluated. Results: The mean of birth weight in different groups of Ramadan fasting time in first, second and third trimester of pregnancy were 3411.52±529.88, 3214.57±463.56 and 3336.86±444.89 gr respectively, which had a statistically significant difference (p=0.03. Frequencies of low birth weight in different groups of Ramadan fasting time in first trimester was 8.9%, in second trimester 8.8% and in third trimester it was 7.1%, which had no statistically significant difference (p=0.9. Among all evaluated factors, only neonatal sex was related to low birth weight. Conclusion: Time of Ramadan fasting during pregnancy does not affect birth weight.

Oral changes observed during pregnancy have been studied for many years, but their magnitude and frequency have not been stressed upon. This study was undertaken to assess the prevalence of oral lesions during different trimesters of pregnancy and their correlation with salivary pH change. The gingival, simplified oral hygiene, community periodontal and decayed-missing-filled teeth indices were used to assess a total of 120 pregnant women (40 in each trimester group) and 40 nonpregnant women (control group). Salivary pH was measured using a digital pH meter. Presence of any oral lesions was determined via oral examination. Scores for all indices increased while salivary pH decreased from the control group to the first trimester group, through to the third. Oral lesions were seen in 44.2% of pregnant women. Lesions were seen in 27.5%, 52.5% and 52.5% of women in the first, second and third trimesters, respectively. The percentage of pregnant women with one oral lesion was highest in the second trimester (47.5%), whereas the third trimester had the highest prevalence (17.5%) of two concurrent oral lesions. The incidence of fissured tongue was highest in the first trimester group, and that of gingival enlargement was highest in the third trimester group. In the second trimester group, there was an almost equal incidence of fissured tongue and gingival/mucosal enlargement. Most changes in oral tissues during pregnancy can be avoided with good oral hygiene. Salivary pH could be used to assess the prevalence of oral lesions in the different trimesters of pregnancy.

Value of sonographic examination and differential diagnosis in cysts of the female breast

1982-08-01

Echography of the breast was performed in 100 women in whom palpation had prompted suspicion of the presence of a cyst. Examination was done with a real-time scanner with a 2.5 or 5 Mhz freely mobile soundhead. Cysts were detected in 56 women by this sonographic method. Approximately 9% of these were complicated cysts requiring surgical treatment. Although sonography facilitates identification of single or of multiple cysts, it will be necessary to perform pneumocystography and X-ray film examination in two projections on first examination in order to exclude complicated cysts, since mere sonographic control after puncture of the cysts is too inaccurate for identifying complicated cysts.

Imaging Findings of Fibrous Hamartoma of Infancy

We wanted to evaluate the imaging findings of fibrous hamartoma of infancy (FHI). We retrospectively reviewed the clinical presentation and the sonographic (n = 5) and CT (n = 3) findings of 5 cases of surgically/pathologically confirmed FHI. The sonographic findings were evaluated according to the location, size, internal echogenicity and vascularity. The CT findings were evaluated according to the attenuation of the mass on both the pre- (n = 3) and postcontrast (n = 2) scans. The image findings were correlated with the pathologic findings. The mean age was 14.8 months (range, 7 months - 3 years). The location of lesions was all in the fatty layer of the back (n = 4) and upper arm (n = 1). All the lesions demonstrated-hypertrichosis on the overlying skin. The lesions measured 31.2 mm in the longest diameter (range: 18 mm - 50 mm). The sonographic findings were purely solid, heterogeneously hyperechoic and hypovacular for all the cases. The internal architecture revealed a 'layering' appearance (n = 3). The CT findings demonstrated isoattenuation, as compared to the adjacent muscle on both the pre- and postcontrast CT scans. The pathologic correlation demonstrated a characteristic 'organoid' mixture of fibrous, mucoid and fatty tissues in all cases. The diagnosis of FHI can be suggested by the sonographic findings of a superficially located, heterogeneous solid mass with a 'layering' appearance in the fatty layer of the back or arms of infants with local hypertrochosis on the overlying skin

Sonographic features of polycystic ovaries consist of elevated antral follicle count or ovarian volume of at least one ovary. The aim of this prospective cross-sectional study was to estimate intraindividual differences in sonographic measurements between the both ovaries of PCOS patients and controls and clinical consequences. Both ovaries of 85 PCOS patients and 48 controls were scanned transvaginally and agreement of sonographic measurements was analyzed using the Bland-Altman method. Concordance correlation coefficients (CCC) were computed. Mean differences between right and left ovaries were 0.24 (95% confidence interval [95% CI]: -0.32-0.80) follicles for AFC and 1.14 (95% CI: 0.34-1.92)ml for OV in the whole study population, 0.14 (95% CI: -0.68-0.96) follicles for AFC and 1.48 (95% CI: 0.39-2.58)ml for OV in PCOS patients, 0.42 (95% CI: -0.19-1.02) follicles for AFC and 0.53 (95% CI: -0.50-1.56)ml for OV in controls. Rather wide limits of agreement and low CCCs (ovaries for both sonographic measurements. Width between lower and upper limits of agreement was higher for PCOS patients than for controls. 23.5% of the PCOS patients showed polycystic ovarian morphology (PCOM) only in one ovary, resulting in 9.4% potentially missed PCOS diagnosis according to the Rotterdam ESHRE/ASRM-Sponsored PCOS Consensus Workshop Group. Substantial differences in antral follicle count and ovarian volume between the right and left ovary were observed. In approximately 10% of the PCOS patients in our study only the examination of both ovaries has led to a reliable diagnosis of PCOS. In clinical practice it is recommended to scan both ovaries for a reliable diagnosis of abnormal sonographic findings in PCOM and PCOS diagnosis. Copyright © 2014 Elsevier Ireland Ltd.

Traditional methods of dating a pregnancy based on history or sonographic assessment have a large variation in the third trimester. We aimed to assess the ability of various quantitative measures of brain cortical folding on MR imaging in determining fetal gestational age in the third trimester. We evaluated 8 different quantitative cortical folding measures to predict gestational age in 33 healthy fetuses by using T2-weighted fetal MR imaging. We compared the accuracy of the prediction of gestational age by these cortical folding measures with the accuracy of prediction by brain volume measurement and by a previously reported semiquantitative visual scale of brain maturity. Regression models were constructed, and measurement biases and variances were determined via a cross-validation procedure. The cortical folding measures are accurate in the estimation and prediction of gestational age (mean of the absolute error, 0.43 ± 0.45 weeks) and perform better than (P = .024) brain volume (mean of the absolute error, 0.72 ± 0.61 weeks) or sonography measures (SDs approximately 1.5 weeks, as reported in literature). Prediction accuracy is comparable with that of the semiquantitative visual assessment score (mean, 0.57 ± 0.41 weeks). Quantitative cortical folding measures such as global average curvedness can be an accurate and reliable estimator of gestational age and brain maturity for healthy fetuses in the third trimester and have the potential to be an indicator of brain-growth delays for at-risk fetuses and preterm neonates. © 2015 by American Journal of Neuroradiology.

This was a hospital-based, cross-sectional observational study. A total of 1764 pregnant women were enrolled during their first trimester of gestation in Wuxi city. Serum ferritin (SF), hemoglobin (Hb), urinary iodine concentrations (UIC), thyroid-stimulating hormone (TSH), free thyroxine (FT4) and free triiodothyronine (FT3) were measured and evaluated in pregnant women. The median of TSH,FT4 and FT3 were 1.53mIU/L,10.43pmol/L and 4.50pmol/L respectively. The median UIC was 200μg/L and the median Hb was 126g/L. Of all the women, 1.76% of the subjects had iron deficiency anaemia (IDA) (SFiron deficiency (ID) (SF100μg/L group, the FT4 level was significantly lower in SF20μg/L group was significantly higher than that in SF 20-100μg/L group (P=0.038) and SF>100μg/L group(P=0.034). There was an inverse linear relationship between TSH and FT4 after log transformation (r=0.245,P=0.000). Moreover, spearman's correlation analysis showed that UIC were correlated with SF and FT3 (all Piron deficiency and iron deficiency anaemia shoud be evaluated and treated to combat thyroid dysfunction during the first trimester of pregnancy, Meanwhile, an increased attention should be paid on iodine nutritional status among this pregnant women simultaneous iron deficiency and thyroid dysfunction.

Embryonic hematopoiesis starts via the generation of primitive red blood cells (RBCs) that satisfy the embryo's immediate oxygen needs. Although primitive RBCs were thought to retain their nuclei, recent studies have shown that primitive RBCs in mice enucleate in the fetal liver. It has been unknown whether human primitive RBCs enucleate, and what hematopoietic site might support this process. Our data indicate that the terminal maturation and enucleation of human primitive RBCs occurs in first trimester placental villi. Extravascular ζ-globin(+) primitive erythroid cells were found in placental villi between 5-7 weeks of development, at which time the frequency of enucleated RBCs was higher in the villous stroma than in circulation. RBC enucleation was further evidenced by the presence of primitive reticulocytes and pyrenocytes (ejected RBC nuclei) in the placenta. Extravascular RBCs were found to associate with placental macrophages, which contained ingested nuclei. Clonogenic macrophage progenitors of fetal origin were present in the chorionic plate of the placenta before the onset of fetoplacental circulation, after which macrophages had migrated to the villi. These findings indicate that placental macrophages may assist the enucleation process of primitive RBCs in placental villi, implying an unexpectedly broad role for the placenta in embryonic hematopoiesis.

Meniscocapsular separation describes detachment of the meniscus from the knee joint capsule. Diagnosis is challenging with conventional examination and imaging methods. We report a case of an 18-year-old female softball catcher with unrevealing magnetic resonance imaging despite continued left knee locking and discomfort with deep squatting. Meniscocapsular separation was revealed only on dynamic sonographic exam, where knee flexion revealed a 3.1-mm gap that developed between the capsule and peripheral meniscus. Arthroscopy confirmed the sonographic findings, and repair resulted in complete resolution of symptoms. This case highlights the utility of dynamic diagnostic sonography in a rare case of posterior lateral meniscocapsular separation.

Many married women in India experience abortion in their second trimester of pregnancy. While there is an impression that second trimester abortions are now overwhelmingly used for sex selection, little is known about the extent to which second trimester abortions are indeed associated with son preference and sex selection motives, relative to other factors. Using data from a community-based study in rural Maharashtra and Rajasthan, research highlights the role of limited access in explaining second trimester abortion. While women with a single child who was a daughter were indeed more likely than other women to have terminated a pregnancy carrying a female foetus in the second trimester, more strikingly, exclusion from abortion-related decision-making, unsuccessful prior attempts to terminate the pregnancy, and distance from the facility in which their abortion was performed, were significantly associated with second trimester abortion, even after controlling for confounding factors. The study calls for greater efficiency in implementing the PCPNDT Act and addressing deep-rooted son preference. At the same time, findings that poverty and limited access to facilities are as, if not more, important drivers of second trimester abortion, highlight the need to meet commitments to ensure accessible abortion facilities for poor rural women.

Controversy exists over psychological risks associated with abortion. The objectives of this study were to examine women's emotions, evaluations, and mental health after an abortion, as well as changes over time in these responses and their predictors. Women arriving at 1 of 3 sites for an abortion of a first-trimester unintended pregnancy were randomly approached to participate in a longitudinal study with 4 assessments-1 hour before the abortion, and 1 hour, 1 month, and 2 years after the abortion. Eight hundred eighty-two (85%) of 1043 eligible women approached agreed; 442 (50%) of 882 were followed for 2 years. Preabortion and postabortion depression and self-esteem, postabortion emotions, decision satisfaction, perceived harm and benefit, and posttraumatic stress disorder were assessed. Demographic variables and prior mental health were examined as predictors of postabortion psychological responses. Two years postabortion, 301 (72%) of 418 women were satisfied with their decision; 306 (69%) of 441 said they would have the abortion again; 315 (72%) of 440 reported more benefit than harm from their abortion; and 308 (80%) of 386 were not depressed. Six (1%) of 442 reported posttraumatic stress disorder. Depression decreased and self-esteem increased from preabortion to postabortion, but negative emotions increased and decision satisfaction decreased over time. Prepregnancy history of depression was a risk factor for depression, lower self-esteem, and more negative abortion-specific outcomes 2 years postabortion. Younger age and having more children preabortion also predicted more negative abortion evaluations. Most women do not experience psychological problems or regret their abortion 2 years postabortion, but some do. Those who do tend to be women with a prior history of depression.

The aim of this prospective study was to evaluate the frequency of postoperative fluid collection after laparoscopic appendectomy in patients with normal postoperative development. Twenty-eight patients were included. The surgical technique, histological data, and postoperative development during the first postoperative month were recorded. A sonographic analysis was performed on the 5th postoperative day by a radiologist who was not aware of the histological and surgical data. Ten cases of fluid collection were found (37%). The frequency was higher in cases of suppurated appendicitis and significantly higher with associated periappendicitis. Peritoneal irrigation or retrocecal dissection did not influence the occurrence of fluid collection. Postoperative serous fluid collection occurs with a high frequency after laparoscopic appendectomies, and one must be careful in interpreting sonographic analyses in looking for deep abscesses in patients with difficult postoperative development.

Full Text Available Abstract Objective: The present study was aimed at investigating bone involvement secondary to rotator cuff calcific tendonitis at ultrasonography. Materials and Methods: Retrospective study of a case series. The authors reviewed shoulder ultrasonography reports of 141 patients diagnosed with rotator cuff calcific tendonitis, collected from the computer-based data records of their institution over a four-year period. Imaging findings were retrospectively and consensually analyzed by two experienced musculoskeletal radiologists looking for bone involvement associated with calcific tendonitis. Only the cases confirmed by computed tomography were considered for descriptive analysis. Results: Sonographic findings of calcific tendinopathy with bone involvement were observed in 7/141 (~ 5% patients (mean age, 50.9 years; age range, 42-58 years; 42% female. Cortical bone erosion adjacent to tendon calcification was the most common finding, observed in 7/7 cases. Signs of intraosseous migration were found in 3/7 cases, and subcortical cysts in 2/7 cases. The findings were confirmed by computed tomography. Calcifications associated with bone abnormalities showed no acoustic shadowing at ultrasonography, favoring the hypothesis of resorption phase of the disease. Conclusion: Preliminary results of the present study suggest that ultrasonography can identify bone abnormalities secondary to rotator cuff calcific tendinopathy, particularly the presence of cortical bone erosion.

The purpose of this study was to evaluate characteristic features of juvenile fibroadenoma of the breast on sonography. Our study included 34 juvenile fibroadenomas confirmed by surgical biopsy or sonographically guided 8-gauge vacuum-assisted biopsy in 23 patients (age range, 15-47 years; mean age, 25 years). Sonographic findings of the lesions were analyzed retrospectively by 2 radiologists in consensus according to the American College of Radiology Breast Imaging Reporting and Data System (BI-RADS) lexicon. The BI-RADS final assessment category was also established. On sonography, all fibroadenomas presented as masses. The mean size was 30 mm. Regarding shape, there were 29 oval, 2 round, and 3 irregular masses. The margins were circumscribed in 24, indistinct in 5, microlobulated in 4, and angular in 1. Regarding echogenicity, 16 masses were hypoechoic, 16 isoechoic, and 2 complex echoic. Posterior acoustic characteristics included posterior acoustic enhancement in 22 masses (65%), posterior shadowing in 1, and no posterior acoustic features in 9; this information was not available in 2. The lesion boundary presented as an abrupt interface in 32 and an echogenic halo in 2. The orientation was parallel in 32 and nonparallel in 2. Calcifications were present in 3 cases and absent in 31. On color Doppler sonography, the masses were usually hypervascular with vessel counts of 5 or more (87%). The BI-RADS final assessment categories were 3 in 24 and 4a in 10. The dominant sonographic presentation of juvenile fibroadenoma is a circumscribed oval hypoechoic or isoechoic mass, which resembles that of simple fibroadenoma. Juvenile fibroadenomas frequently show posterior acoustic enhancement and hypervascularity on color Doppler sonography. © 2014 by the American Institute of Ultrasound in Medicine.

Sonographic findings of nine cases of intramural hematoma of the gastrointestinal tract are presented. The duodenum was the most common site, followed by the ascending colon and the stomach. Intramural hematomas present as centrally or eccentrically located bowel mass of variable echogenicity: heter-ogeneously echogenic in six cases; hypoechoic in two case; anechoic in one case. In five cases of duodenal hematoma, the stomach and/or duodenal bulb were distended and filled with fluid. It is concluded that ultrasonography is a simple and useful tool in the diagnosis of intramural hematoma of the intestine

Full Text Available Background and Objectives: Ankle foot complex is the part of the body which is in contact with the ground and it is important to have an intact proprioceptive system in order to maintain postural control. Previous study has established that there is significant difference between ankle proprioception in pregnant women in their third trimester and non-pregnant women. There is lack of literature regarding when the ankle does the ankle proprioception gets affected during pregnancy and whether this change reverts back during postpartum and hence this study. Method: A cohort of 70 primiparous women were included in the study and the women were followed through 12th week, 24th week, 32nd week , immediate postpartum and 6 weeks postpartum. The ankle repositioning error was measured using photography method and was analyzed using UTHSCSA Image tool software. Repeated measures ANOVA was used to measure the differences across various time periods. Results: It was found that there was a significant differences (p<0.001 in ankle repositioning error in pregnant women across the trimesters and in the postpartum period and the value did not reach the first trimester value even after six weeks postpartum. Conclusion: Ankle proprioception was significantly affected across the various trimesters of pregnancy with the peak variability observed in the third trimester and the value did not reach back to the first trimester value even after 6 weeks postpartum.

To evaluate the sonographic findings of fetal congenital intracranial teratoma. From 1994 to 2002, of the 11 fetuses which had been diagnosed with fetal intracranial tumors after second level fetal ultrasonography, the six that were confirmed after autopsy as congenital intracranial teratomas were included in our study. The sonographic findings, including size, homogeneity, echogenicity compared with surrounding normal brain tissues, cystic components, and tumor related calcification, were retrospectively evaluated. The incidence of fetal congenital intracranial teratoma out of all fetal intracranial tumors was 54.5% (6 of 11 cases) during the 8-year period. The mean mass size was 7.4 cm (3.0-15.0 cm). Two thirds of (4/6) of the teratoma cases showed high echogenicity compared with normal brain tissues, and two thirds (4/6) showed heterogeneous echogenicity. Four teratoma cases (67%) showed cysts in the mass with a mean size of 1.9cm. One third (2/6) showed calcifications within the tumor. Out of the six cases, two had oropharyngeal teratoma with extension into the intracranial portion (so called epignathus) and showed homogenous mass without any cysts or calcifications. The typical sonographic appearance of intracranial teratoma was a heterogeneous, hyperechoic mass with cysts. In the epignathus cases, the sonographic appearances differed somewhat from the others. An understanding of the sonographic findings of fetal intracranial teratoma will help in the timely counseling of the parents and in obstetric decision making

To determine the efficacy of maternal administration of intravenous amino acid solution in improving amniotic fluid volume in cases of isolated oligohydramnios and to observe its impact on mode of delivery and neonatal outcome. Study Design: A prospective case series. Methodology: Forty two women with singleton pregnancy, well established gestational age and clinically and sonographically proven isolated oligohydramnios in the third trimester before 36 weeks were administered amino acid solution intravenously after excluding cases of premature rupture of membranes, congenital anomaly of fetus, maternal pulmonary, cardiovascular and hypertensive disorders, and severe placental insufficiency (raised S/D ratio). Pre-infusion and postinfusion Amniotic fluid Index (AFI) was measured and repeated weekly. Women were followed till delivery. Results: According to repeated measurement analysis of variance, mean pre-infusion AFI was 4.7 cm, mean one week postinfusion AFI was 5.8 cm, mean two week post-infusion AFI was 6.2 cm and mean three week AFI was 6.3 cm (p-value 0.029, significant). Cesarean section became a predominant mode of delivery in this group without a firm evidence of associated fetal compromise. Conclusion: Amino acid infusion is an effective therapy for raising AFI in isolated oligohydramnios in this case series. Liberal use of cesarean section in this selected group should be carefully re-evaluated. (author)

2005-01-01

Objective: To develop a pre -natal screening program for fetal chromosome abnormalities based on risk values calculated from maternal serum markers levels during the second trimester. Methods: Serum levels of AFP, β-HCG, uE 3 were determined with CLIA in 1048 pregnant women during 14-21w gestation period and the results were analyzed with a specific software (screening program for Down' s syndrome developed by Beckman) for the risk rate. In those women defined as being of high risk rate, cells from amniotic fluid or umbilical cord blood were studied for karyotype analysis. Results: Of these 1048 women, 77 were designated as being of high risk rate for several chromosome abnormalities i.e. Down's syndrome, open spina bifida and trisomy -18 syndrome (overall positive rate 7.3%). Further fetal chromosome study in 31 of them revealed three proven cases of abnormality. Another cord blood study was performed in a calculated low risk rate case but with abnormal sonographic finding at 31 w gestation and proved to be abnormal (software study false negative). The remaining 46 high risk rate cases either refused future study (n=35) or were lost for follow-up (n=11). Fortunately, all the 35 women refused further study gave birth to normal babies without any chromosome abnormalities discovered on peripheral blood study. Besides, in a trial study, five high risk rate women were again evaluated a few weeks later but with tremendous difference between the results. Conclusion: The present program proves to be clinically useful but needs further study and revision. Many factors may influence the result of the analysis and the duration of gestation period in weeks should be as accurate as possible. At present, in order to avoid getting false negatives, we don't advise a second check in 'high risk' cases. (authors)

Cheng, Ju-Wen; Tsai, Wen-Chung; Yu, Tung-Yang; Huang, Kuo-Yao

2012-01-01

To evaluate the intra- and interrater reliability of ultrasonographic measurements of the thickness and echogenicity of the plantar fascia. Eleven patients (20 feet), who complained of inferior heel pain, and 26 volunteers (52 feet) were enrolled. Two sonographers independently imaged the plantar fascia in both longitudinal and transverse planes. Volunteers were assessed twice to evaluate intrarater reliability. Quantitative evaluation of the echogenicity of the plantar fascia was performed by measuring the mean gray level of the region of interest using Digital Imaging and Communications in Medicine viewer software. Sonographic evaluation of the thickness of the plantar fascia showed high reliability. Sonographic evaluations of the presence or absence of hypoechoic change in the plantar fascia showed surprisingly low agreement. The reliability of gray-scale evaluations appears to be much better than subjective judgments in the evaluation of echogenicity. Transverse scanning did not show any advantage in sonographic evaluation of the plantar fascia. The reliability of sonographic examination of the thickness of the plantar fascia is high. Mean gray-level analysis of quantitative sonography can be used for the evaluation of echogenicity, which could reduce discrepancies in the interpretation of echogenicity by different sonographers. Longitudinal instead of transverse scanning is recommended for imaging the plantar fascia. Copyright © 2011 Wiley Periodicals, Inc.

Full Text Available Objectives: Non-invasive methods of inducing a miscarriage are now considered an effective alternative to surgical evacuation (dilatation and curettage. This study aimed to evaluate the effectiveness of misoprostol in the termination of first-trimester miscarriages. Methods: This prospective study was conducted between October 2009 and September 2010 and assessed all patients admitted to the Royal Hospital in Muscat, Oman, for the termination of first-trimester miscarriages during the study period. All patients received misoprostol and the rates of successful termination were measured. Patient satisfaction was assessed using a short questionnaire. Results: A total of 290 women were included in the study. Termination with misoprostol was successful in 61.38% of the subjects. Of the remaining subjects requiring additional surgical evacuation (n = 112, 58.93% required evacuation due to failed termination with misoprostol and 65.18% underwent early evacuation (≤24 hours since their last misoprostol dose. The majority of patients experienced no side-effects due to misoprostol (89.66%. Pain was controlled with simple analgesics in 70.00% of the subjects. A high satisfaction rate (94.83% with the misoprostol treatment was reported. Conclusion: Misoprostol was a well-tolerated drug which reduced the rate of surgical evacuation among the study subjects. This medication can therefore be used safely in the management of incomplete miscarriages.

To review the sonographic findings of various diseases showing architectural distortion depicted under mammography. We collected and reviewed architectural distortions observed under mammography at our health institution between 1 March 2004, and 28 February 2007. We collected 23 cases of sonographically-detected mammographic architectural distortions that confirmed lesions after surgical resection. The sonographic findings of mammographic architectural distortion were analyzed by use of the BI-RADS lexicon for shape, margin, lesion boundary, echo pattern, posterior acoustic feature and orientation. There were variable diseases that showed architectural distortion depicted under mammography. Fibrocystic disease was the most common presentation (n = 6), followed by adenosis (n = 2), stromal fibrosis (n = 2), radial scar (n = 3), usual ductal hyperplasia (n = 1), atypical ductal hyperplasia (n = 1) and mild fibrosis with microcalcification (n = 1). Malignant lesions such as ductal carcinoma in situ (DCIS) (n = 2), lobular carcinoma in situ (LCIS) (n = 2), invasive ductal carcinoma (n = 2) and invasive lobular carcinoma (n = 1) were observed. As observed by sonography, shape was divided as irregular (n = 22) and round (n = 1). Margin was divided as circumscribed (n = 1), indistinct (n = 7), angular (n = 1), microlobulated (n = 1) and sipculated (n = 13). Lesion boundary was divided as abrupt interface (n = 11) and echogenic halo (n = 12). Echo pattern was divided as hypoechoic (n = 20), anechoic (n = 1), hyperechoic (n = 1) and isoechoic (n = 1). Posterior acoustic feature was divided as posterior acoustic feature (n = 7), posterior acoustic shadow (n = 15) and complex posterior acoustic feature (n = 1). Orientation was divided as parallel (n = 12) and not parallel (n = 11). There were no differential sonographic findings between benign and malignant lesions. This study presented various sonographic findings of mammographic architectural distortion and that it is

In 33 patients (18 cystic echinococci, 15 alveolar) both methods produced the following findings which could be correlated with the pathological results: single or multi-centric lesions, sharp or indefinite demarkation and abnormalities in the shape and size of the liver. The sonographic findings were analysed with respect to the echo characteristics, whereas the computer tomographically demonstrated lesions were examined densitometrically in order to show calcification. Both methods demonstrate the pathological changes satisfactorily. Computer tomography is more effective in alveolar echinococcus lesions by showing the different types of calcification, whereas sonography provides a more accurate picture of the internal structure of the cysts in cystic echinococcus. Comparison of the methods in 19 patients examined by both showed a high accuracy in each method, but sonography was relatively poor in demonstrating lesions in the spleen.

Diagnosis of Pentalogy of Cantrell in the First Trimester Using Transvaginal Sonography and Color Doppler

Directory of Open Access Journals (Sweden)

2015-01-01

Full Text Available We report the prenatal diagnosis of Cantrell syndrome in the first trimester. During a routine transabdominal ultrasonographic examination, a midline supraumbilical abdominal wall defect including herniated liver and ectopia cordis with a large omphalocele containing the intestines and cystic hygroma was incidentally identified at the 12th week of gestation. A transvaginal sonography examination revealed a severe lumbosacral scoliosis in addition to the inability to visualize the abdominal aorta which was indicative of a severe intracardiac defect. The parents opted for pregnancy to be terminated. In this case report, we discuss the complementary role of transvaginal sonography and Doppler imaging in the diagnosis of Cantrell syndrome in early pregnancy.

Balancing the need to provide individual support for patients and the need for an efficient clinic can be challenging in the abortion setting. This study explores physician, staff, and specially trained abortion doula perspectives on doula support, one approach to patient support. We conducted separate focus groups with physicians, staff members, and doulas from a high-volume, first-trimester aspiration abortion clinic with a newly established volunteer abortion doula program. Focus groups explored 1) abortion doula training, 2) program implementation, 3) program benefits, and 4) opportunities for improvement. Interviews were transcribed and computer-assisted content analysis was performed; salient findings are presented. Five physicians, 5 staff members, and 4 abortion doulas participated in separate focus group discussions. Doulas drew on both their prior personal skills and experiences in addition to their abortion doula training to provide women with support at the time of abortion. Having doulas in the clinic to assist with women's emotional needs allowed physicians and staff to focus on technical aspects of the procedure. In turn, both physicians and staff believed that introducing doulas resulted in more patient-centered care. Although staff did not experience challenges to integrating doulas, physicians and doulas experienced initial challenges in incorporating doula support into the clinical flow. Staff and doulas reported exchanging skills and techniques that they subsequently used in their interactions with patients. Physicians, clinic staff, and doulas perceive abortion doula support as an approach to provide more patient-centered care in a high-volume aspiration abortion clinic. © 2018 by the American College of Nurse-Midwives.

Pelvic infections are a serious and widespread gynecological disease, often leading to sterility. Procedures like evacuation of the products of conception by vacuum suction are known to facilitate their appearance. 300 patients were examined the same day of the abortion (first trimester); before the hysterosuction a vaginal tampon was taken from the cervix and from the posterior fornix. The patients were invited to come back for an exam in two weeks and to refer to the clinic for any problem before then. A wet mount, aerobic and anaerobic cultures in several media and Gram stains were used to identify the pathogens. 40.3% of the tampons were positive for pathogens, mostly staphilococci (52%), but also Candida, alfa and beta hemolytic Streptococci, Proteus, E. Coli, Trichomonas. 5 patients had serious complications that required hospital admission. Only 128 patients showed up for the postoperative control; of these, 14 presented with symptoms of pelvic infection. Since pelvic infections are the most frequent complication after induced abortion, and considering the larege number of women who carry vaginal pathogens, the Authors strongly recommend a guided antibiotic profilaxis before the hysterosuction operation.

Objective measures of clinical improvement in patients with acute heart failure (AHF) are lacking. The aim of this study was to determine whether repeated lung sonography could semiquantitatively capture changes in pulmonary edema (B-lines) in patients with hypertensive AHF early in the course of treatment. We conducted a feasibility study in a cohort of adults with acute onset of dyspnea, severe hypertension in the field or at triage (systolic blood pressure ≥ 180 mm Hg), and a presumptive diagnosis of AHF. Patients underwent repeated dyspnea and lung sonographic assessments using a 10-cm visual analog scale (VAS) and an 8-zone scanning protocol. Lung sonographic assessments were performed at the time of triage, initial VAS improvement, and disposition from the emergency department. Sonographic pulmonary edema was independently scored offline in a randomized and blinded fashion by using a scoring method that accounted for both the sum of discrete B-lines and degree of B-line fusion. Sonographic pulmonary edema scores decreased significantly from initial to final sonographic assessments (P < .001). The median percentage decrease among the 20 included patient encounters was 81% (interquartile range, 55%-91%). Although sonographic pulmonary edema scores correlated with VAS scores (ρ = 0.64; P < .001), the magnitude of the change in these scores did not correlate with each other (ρ = -0.04; P = .89). Changes in sonographic pulmonary edema can be semiquantitatively measured by serial 8-zone lung sonography using a scoring method that accounts for B-line fusion. Sonographic pulmonary edema improves in patients with hypertensive AHF during the initial hours of treatment. © 2017 by the American Institute of Ultrasound in Medicine.

To assess the performance of third-trimester fetal biometry and fetal Doppler studies for the prediction of small-for-gestational-age (SGA) neonates, and to explore contingency strategies using a first-trimester prediction model based on maternal and fetal parameters and third-trimester ultrasound. This was an observational cross-sectional study of uncomplicated singleton pregnancies. Risk assessment for chromosomal abnormality was carried out in 4702 pregnancies using a combination of ultrasound markers (fetal nuchal translucency thickness (NT) and nasal bone assessment) and biochemistry (free beta-human chorionic gonadotropin (β-hCG) and pregnancy-associated plasma protein-A (PAPP-A)) at 11 to 13 + 6 weeks. Maternal demographic characteristics and method of conception were recorded. Third-trimester (30-34 weeks) fetal biometry (biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC) and femur length (FL)) and umbilical artery (UA) and middle cerebral artery Doppler studies were performed routinely in a subgroup (n = 2310). Reference ranges for birth weight were constructed using the cohort of 4702 women, and neonates were classified as small (SGA, ≤ 5th centile) or appropriate (AGA) for gestational age. First-trimester, third-trimester and integrated first- and third-trimester prediction models for SGA were constructed using regression analysis and three different contingency strategies of rescanning in the third trimester were investigated. According to the areas under the receiver-operating characteristics curves (AUCs), AC (AUC = 0.85) and ultrasound-estimated fetal weight (EFW, AUC = 0.87) were equally good predictors of SGA. The model was marginally improved by the addition of UA Doppler, smoking status and first-trimester indices (free β-hCG and PAPP-A multiples of the median) (combined model, AUC = 0.88), but the difference was not statistically significant. A contingency strategy of rescanning 50% of the population in the

AIM: This study was undertaken to investigate variations in the vascularity and grey-scale sonographic features of cervical lymph nodes with their size. MATERIALS AND METHODS: High resolution grey-scale sonography and power Doppler sonography were performed in 1133 cervical nodes in 109 volunteers who had a sonographic examination of the neck. Standardized parameters were used in power Doppler sonography. RESULTS: About 90% of lymph nodes with a maximum transverse diameter greater than 5 mm showed vascularity and an echogenic hilus. Smaller nodes were less likely to show vascularity and an echogenic hilus. As the size of the lymph nodes increased, the intranodal blood flow velocity increased significantly (P 0.05). CONCLUSIONS: The findings provide a baseline for grey-scale and power Doppler sonography of normal cervical lymph nodes. Sonologists will find varying vascularity and grey-scale appearances when encountering nodes of different sizes. Ying, M. et al. (2001)

We aimed to evaluate placental stiffness measured by acoustic radiation force impulse (ARFI) elastography in pregnant women in the second trimester with a normal fetus versus those with structural anomalies and non-structural findings. Forty pregnant women carrying a fetus with structural anomalies diagnosed sonographically at 18-28 weeks of gestation comprised the study group. The control group consisted of 34 healthy pregnant women with a sonographically normal fetus at a similar gestational age. Placental shear wave velocity (SWV) was measured by ARFI elastography and compared between the two groups. Structural anomalies and non-structural findings were scored based on sonographic markers. Placental stiffness measurements were compared among fetus anomaly categories. Doppler parameters of umbilical and uterine arteries were compared with placental SWV measurements. All placental SWV measurements, including minimum SWV, maximum SWV, and mean SWV were significantly higher in the study group than the control group ([0.86 ± 0.2, 0.74 ± 0.1; p < 0.001], [1.89 ± 0.7, 1.59 ± 0.5; p = 0.04], and [1.26 ± 0.4, 1.09 ± 0.2; p = 0.01]), respectively. Placental stiffness evaluated by ARFI elastography during the second trimester in pregnant women with fetuses with congenital structural anomalies is higher than that of pregnant women with normal fetuses.

Small cross-sectional studies are published on the trimester-specific normal ranges of thyrotropin and thyroxine levels in Indian women from various parts of the country. We sought to review the published literature on thyroid function tests in normal pregnant Indian women to see if the pooled data from various studies can define normative data and hypothyroidism in pregnancy. We retrieved 56 studies from online databases with detailed search using multiple search terms. Unanimously eight studies were finalized. Data of 2703 pregnant women (age 16-45 years; 966 were in the first trimester, 1072 in their second trimester, and 1037 women in their third trimester) were analyzed. All eight studies included singleton pregnancies from the northern and eastern part of India with seven studies being cross-sectional in nature. The exclusion criteria in all studies included those with historical/clinical evidence of thyroid dysfunction, those with family history of thyroid dysfunction, infertility and those with history of recurrent miscarriages (usually >3). Ultrasound evidence of thyroid disease, urinary iodine assessment, and thyroid antibodies were included as additional exclusion criteria in two, three, and four studies, respectively. None of the studies included the outcome of pregnancy as part of follow-up. As part of the pooled data analysis, the 5 th -95 th centile values of normal TSH extended from 0.09 to 6.65 IU/mL in the first trimester, 0.39-6.61 IU/mL in the second trimester, and 0.70-5.18 IU/mL in the third trimester. The FT4 levels (5 th -95 th centile values) extended from 8.24 to 25.74 pmol/L in the first trimester, 6.82-26.0 pmol/L, and 5.18-25.61 pmol/L in the third trimester. With due limitations imposed by the quality of the available studies, the current review suggests that upper normal limit of TSH values can extend up to 5-6 IU/mL in pregnancy.

To investigate the usefulness of sonography for the evaluation of osteoarthritic articular cartilage. Ten asymptomatic volunteers and 20 patients with osteoarthritis of the knee underwent sonographic evaluation. For this, the knee was maintained of full flexion in order to expose the deep portion of femoral condylar cartilage. Both transverse and longitudinal scans were obtained in standardized planes. Sonographic images of the articular cartilages were analyzed in terms of surface sharpness, echogenicity and thickness, along with associated bone changes. Normal cartilages showed a clearly-defined surface, homogeneously low echogenicity and regular thickness. Among 20 patients, the findings for medial and lateral condyles, respectively, were as follows: poorly defined cartilage surface, 16 (80%) and ten (50%); increased echogenicity of cartilage, 17 (85%) and 16 (80%); cartilage thinning, 16 (80%) and 14 (70%) (two medial condyles demonstrated obvious cartilage thickening); the presence of thick subchondral hyperechoic bands, five (25%) and four (20%); the presence of osteophytes, 13 (65%) and 12 (60%). Sonography is a convenient and accurate modality for the evaluation of femoral articular cartilage. In particular, it can be useful for detecting early degenerative cartilaginous change and for studying such change during clinical follow-up. (author)

Abstract Introduction: Visual search is a task that humans perform in everyday life. Whether it involves looking for a pen on a desk or a mass in a mammogram, the cognitive and perceptual processes that underpin these tasks are identical. Radiologists are experts in visual search of medical images and studies on their visual search behaviours have revealed some interesting findings with regard to diagnostic errors. In Australia, within the modality of ultrasound, sonographers perform the diag...

The sirenomelia sequence with fusion, rotation, hypotrophy or atrophy of the lower limbs in combination with severe urogenital and gastrointestinal malformations is a rare and usually lethal disorder. We present the case of a 28-year-old woman, who was referred to our department because of an intraabdominal cystic structure in the 9th week of gestation. Subsequent scans confirmed the diagnosis of a sirenomelia sequence with the fusion of the lower extremities without fusion of the bones according to Stocker I classification. The size of the intraabdominal cyst decreased during follow-up. After counseling, termination of pregnancy was induced. The postmortem X-ray confirmed the ultrasound diagnosis. The exact etiological mechanism of this malformation is still unknown. An early alteration of the embryological vascular network damaging the caudal mesoderm is thought to lead to arrested development of the lower limbs and other affected organs. The cyst we saw in the 9th week might fit with this theory, either as an expression of the complex malformation of the lower abdomen or as the sonographic appearance of necrosis.

Objective: To describe the potential of modern sonographic techniques in paediatric uroradiology. Method: Ultrasound (US)--now being the primary imaging tool--has revolutionised imaging diagnostic in the urinary tract. Constant developments and technical refinements have secured the role of US in uroradiology. Colour Doppler Sonography (CDS) and innovative applications such as the transperineal approach or application of m-mode US to the urinary tract have helped to develop US from just a basic tool to a sophisticated and respected method. The ongoing introduction of new and even more sophisticated methods further enhance the sonographic potential, which shall be demonstrated by a more detailed discussion of these methods. Results: Harmonic imaging, extended field of view US, amplitude coded CDS, echo-enhanced US, and three-dimensional US as the most recent new sonographic techniques are successfully applicable to paediatric urinary tract disease. They improve sonographic diagnosis in many conditions, such as detection of vesico-ureteral reflux, renal parenchymal volume assessment, comprehensive visualisation of hydronephrosis and complex pathology, evaluation of renal perfusional disturbances or defects, superior documentation with improved comparability for follow-up, or simply by offering clearer tissue delineation and differentiation. Conclusion: Modern US techniques are successfully applicable to neonates, infants, and children, further boosting the value of US in the paediatric urinary tract. However, as handling became more sophisticated, and artefacts have to be considered, modern urosonography became not only a more powerful, but also a more demanding method, with the need for expert knowledge and dedicated training.

2013-01-01

The current state of knowledge is reviewed with respect to the realization of lower limbs venous mapping. Venous mapping is obtained by the use of color and spectral Doppler ultrasound. Doppler ultrasound has provided a precise graphical representation of the superficial and deep venous systems. The performance of the venous mapping is considered essential for the correct handling of venous diseases. The anatomical and pathophysiological basic concepts are defined to realize the sonographic assessment of the veins of the lower limbs. The required technical aspects are revised for the realization of sonographic exploration of the patient with venous insufficiency. Sonographic findings are characterized to support the diagnostic of venous insufficiency of the lower limbs. The CEAP (clinical-etiologic-anatomic-pathophysiologic) classification is utilized to differentiate forms and degrees of severity of the disorder, and has allowed an interinstitutional comparison in clinical studies, the evaluation of treatment and monitoring of patients. A proposal is designed to perform reports that have served of guide surgical to vascular surgeons [es

To retrospectively evaluate the accuracy of ultrasound as a diagnostic method for differentiating acute diverticulitis from colon cancer in patients with sigmoid colon stenosis. Ultrasound examinations of 91 consecutive patients with sigmoid stenosis (50 diverticulitis and 41 colon cancers) were reviewed by two trained radiologists. Sixty-five (71%) patients presented with acute abdominal symptoms. Thirteen sonographic criteria retrieved from the literature were evaluated to differentiate benign from malignant strictures. A score including all parameters which showed significant differences between benign vs. malignant was built. Sensitivity, specificity, accuracy, and positive or negative predictive values of each sonographic sign, the overall diagnosis, and sonographic score were calculated. Loss of the bowel wall stratification was the most reliable criteria for the diagnosis of malignancy (92% and 94% of sensitivity and specificity, respectively), and the best inter-radiologist agreement (κ = 0.848). Adjacent lymph nodes were the most specific feature (98%) for colon cancer, but its sensitivity was low. Global assessment could differentiate both diseases with high sensitivity (92-94.9%) and specificity (98-100%). Sonographic score >3 enabled differentiation of carcinoma from diverticulitis with 95% sensitivity and 92-94% specificity, with an area under the ROC curve of 0.98-0.987. There were no significant differences in the results between patients with acute and nonacute abdominal symptoms. The combination of several morphological sonographic findings using a score can differentiate most cases of diverticulitis from colon carcinoma in sigmoid strictures.

Very widespread in our clinical setting, early-onset sepsis is due to organisms that commonly colonize or infect the maternal genital tract; identifying such organisms would help improve prevention and treatment. To determine the bacterial ecology and the pathological status of the genital organs during the last trimester of pregnancy, in order to evaluate the risk of materno-fetal infections and to improve the present prophylactic measures based on monitoring bacterial carriage during the first trimester. Vaginal and endocervical samples, usually taken during the first trimester of pregnancy were delayed and taken during the last trimester of pregnancy, in patients with no signs of sepsis and not taking antibiotics. A macroscopic examination described the aspect of the vagina, the cervix uteri, leukorrhea and possible inflammatory lesions or ulcerations. A microscopic examination searched for parasites, epithelial cells, Clue cells and leukocytes. The appropriate bacteriological cultures were performed after reading the Gram stain and scoring the vaginal flora. The clinical and cytobacteriological aspects were used to identify the bacterial ecology and the pathological genital states. Genital samples were collected from 306 pregnant women. Among them 118 were at 29-32 weeks of gestation, 104 at 33-36 and 84 at 37-40. The most frequent germs were C. albicans (33.3%), Enterobacteriaceae (20.3%) including E. coli (10.9%), S. aureus (15.4%), Gardnerella (13.6%), and Trichomonas (10.6%), in monomicrobian (79.2%) or polymicrobian carriage (20.8%). Lower genital tract pathological states such as vaginitis (29.4%), bacterial vaginosis (21.5%) or cervicitis (10.4%) and asymptomatic bacterial carriage (23.5%) and normal genital flora (15%) were identified. This is the first report of genital bacterial carriage in African women during the last trimester of pregnancy. Larger studies are required to evaluate the risk of maternofetal infections and to improve current

We aimed to investigate the association of pregnancy associated plasma protein A (PAPP-A) levels in late first trimester with small for gestational age (SGA) neonates and adverse pregnancy outcomes in a low-income setting. The inclusion criteria were late first trimester (11-13 + 6 weeks) women with singleton and non-anomalous pregnancy. Enrolled participants were sampled for PAPP-A and prospectively followed up for delivery outcome and antenatal complications. A multiple of median (MoM) was calculated and statistically compared between groups. Out of total 284 subjects, 14.54% delivered SGA babies and formed cases (Group A), 66.5% delivered appropriate for gestational age (AGA) neonates with uneventful antenatal period (controls, Group B), and 19.3% were AGA group with adverse pregnancy complications (Group C). The late first trimester median PAPP-A MoM was significantly lower (0.61) in Group A compared to Group B (1.47). Using receiver operating characteristic (ROC) curve for PAPP-A MoM, optimal cutoff value was found at 0.45 MoM, with positive predictive value of 56.2%, specificity of 92.6% and sensitivity of 45%. The median interquartile range (IQR) of PAPP-A MoM value in Group C in comparison with Group B was significantly lower except for abruption. At PAPP-A MoM cutoff value <1, <0.8, <0.6 and <0.4, the odds ratio for adverse pregnancy outcome was 8.30, 7.29, 10.97 and 10.60, respectively, indicating an inverse relationship. With 0.45 MoM cutoff of PAPP-A, the detection rate, specificity and positive predictive value for SGA were 45, 92.6 and 56.2%, respectively. As PAPP-A MoM values decreased, the odds ratio of having adverse pregnancy outcomes increased.

To assess the diagnostic value of maternal CA 125 in patients with symptomatic first trimester pregnancy and to evaluate the prognostic significance of CA 125 versus beta-hCG in early pregnancies with intact fetal heartbeat, complicated by vaginal bleeding. Two prospective open-label studies with longitudinal follow-up in the second trial. Academic Department of Obstetrics and Gynecology, University of Cologne. Study 1: 168 patients presenting between gestational weeks 6 and 12 with: extrauterine pregnancy, 29; missed abortion, 50; incomplete spontaneous abortion, 38; imminent abortion, 33; and normal pregnancy (no history of endometriosis or ovarian mass), 18. Study 2: Fifty consecutive patients with vaginal bleeding during gestational weeks 6-12 all of whom having demostrable fetal heartbeat. Eighteen patients finally aborted whereas the remainder had normally continuing pregnancy until term. Study 1: Single serum determinations of CA 125 and beta-hCG were correlated with the different disorders observed. Study 2: Two sequential measurements of serum CA 125 and beta-hCG performed within a 5-7 days interval were related to the outcome of pregnancy as indicated by changes of the ultrasound presentation, miscarriage, future hospitalization, or delivery. Study 1: Patients with vaginal bleeding generally had higher median CA 125 values (38 IU/ml; range 1.3-540) compared to non-bleeding patients (17.8 IU/ml; range 1.0-157). No statistically significant differences in regard to median serum CA 125 levels between symptomatic and normal pregnancies occurred: normal pregnancy, 25.5 IU/ml (range 3.2-97); ectopic pregnancy, 26 IU/ml (range 1.3-157); missed abortion, 19.1IU/ml (range 1-242); threatened abortion, 48 IU/ml (range 5.2-540); spontaneous abortion, 40 IU/ml (range 5.4-442). Study 2: Initial CA 125 levels did not differ significantly between both groups of patients with 27/32 non-aborters and 13/18 aborters showing concentrations below 65 IU/ml. After 5-7 days, CA

To test if maternal hemodynamics and bioimpedance, assessed at the time of combined screening for PE, are able to identify in the first trimester of gestation normotensive non-obese patients at risk for pre-eclampsia (PE) and/or intrauterine growth restriction (IUGR). One hundred and fifty healthy nulliparous non-obese women (body mass index < 30 kg/m 2 ) in the first trimester of pregnancy underwent assessment by UltraSonic Cardiac Output Monitor (USCOM) to detect hemodynamic parameters, bioimpedance analysis to characterize body composition, and combined screening for PE (assessment of maternal history, biophysical and maternal biochemical markers). Patients were followed until term, noting the appearance of PE and/or IUGR. One hundred and thirty-eight patients had an uneventful pregnancy (controls), while 12 (8%) developed complications (cases). USCOM showed, in cases compared with controls, lower cardiac output (5.6 ± 0.3 vs 6.7 ± 1.1 L/min, P < 0.001), lower inotropy index (1.54 ± 0.38 vs 1.91 ± 0.32 W/m 2 , P < 0.001) and higher total vascular resistance (1279.8 ± 166.4 vs 1061.4 ± 179.5 dynes × s/cm 5 , P < 0.001). Bioimpedance analysis showed, in cases compared with controls, lower total body water (53.7 ± 3.3% vs 57.2 ± 5.6%, P = 0.037). Combined screening was positive for PE in 8% of the controls and in 50% of the cases (P < 0.001). After identification of cut-off values for USCOM and bioimpedance parameters, forward multivariate logistic regression analysis identified as independent predictors of complications in pregnancy the inotropy index (derived by USCOM), fat mass (derived from bioimpedance analysis) and combined screening. Combined screening for PE and assessment of bioimpedance and maternal hemodynamics can be used to identify early markers of impaired cardiovascular adaptation and body composition that may lead to complications in the third trimester of pregnancy.

Solar cycle predicts folate-sensitive neonatal genotypes at discrete phases of the first trimester of pregnancy: a novel folate-related human embryo loss hypothesis.

Science.gov (United States)

Folate, a key periconceptional nutrient, is ultraviolet light (UV-R) sensitive. We therefore hypothesise that a relationship exists between sunspot activity, a proxy for total solar irradiance (particularly UV-R) reaching Earth, and the occurrence of folate-sensitive, epigenomic-related neonatal genotypes during the first trimester of pregnancy. Limited data is provided to support the hypothesis that the solar cycle predicts folate-related human embryo loss: 379 neonates born at latitude 54°N between 1998 and 2000 were examined for three folate-sensitive, epigenome-related polymorphisms, with solar activity for trimester one accessed via the Royal Greenwich Observatory-US Air force/National Oceanic and Atmospheric Administration Sunspot Database (34,110 total observation days). Logistic regression showed solar activity predicts C677T-methylenetetrahydrofolate reductase (C677T-MTHFR) and A66G-methionine synthase reductase (A66G-MSR) genotype at discrete phases of trimester one. Total and maximal sunspot activity predicts C677T-MTHFR genotype for days 31-60 of trimester one (p=0.0181 and 0.0366, respectively) and A66G-MSR genotype for days 61-90 of trimester one (p=0.0072 and 0.0105, respectively). Loss of UV-R sensitive folate associated with the sunspot cycle might therefore interact with variant folate genes to perturb DNA methylation and/or elaboration of the primary base sequence (thymidylate synthesis), as well as increase embryo-toxic homocysteine. We hypothesise that this may influence embryo viability leading to 677CC-MTHFR and 66GG-MSR embryo loss at times of increased solar activity. This provides an interesting and plausible link between well recognised 'folate gene originated developmental disorders' and 'solar activity/seasonality modulated developmental disorders'.

We recommend that all pregnancies ending spontaneously beyond the first trimester are included in the national birth registry and described by appropriate variables....

Intrauterine shelves in pregnancy: sonographic observations.

Science.gov (United States)

Brown, D L; Felker, R E; Emerson, D S

1989-10-01

Twenty-five shelves of tissue, all having a free edge within the uterine cavity, were identified by sonography in 24 singleton pregnancies. In no case did the shelf attach to the fetus or restrict fetal motion. The fetus was sonographically normal in 23 pregnancies, and no fetus developed amniotic-band syndrome. One fetus had anencephaly, probably unrelated to amniotic-band syndrome. Although these shelves may be due to synechiae, only eight (32%) of the patients had a history of dilatation and curettage or cesarean delivery, which predispose the patient to formation of synechiae. This experience suggests that when a shelf of tissue with a free edge is present within the pregnant uterus, there should be no concern for the development of amniotic-band syndrome as long as a complete sonographic survey of the fetus reveals no abnormalities.

To describe and evaluate recruitment techniques used to enroll 152 healthy pregnant women fewer than 15 weeks gestation into a prospective study of environmental chemical exposure during pregnancy. Posters, a website, online and print advertising, recruitment emails, media coverage, recruitment from clinic waiting rooms, networking within the pregnancy community and presenting a study booth at baby "trade shows" were used to advertise the study. Participants had to meet a strict set of eligibility criteria, and were asked to donate two-second-trimester blood samples, complete two questionnaires, have samples of air, dust, lint and tap water collected from their homes, and donate a cord blood sample at delivery. Over 17 months, 171 women enrolled (49% of initial contacts, and 99% of all eligible women) and 152 women completed the study (89% retention). Total recruitment costs were approximately $400 Cdn per final participant. Posters, study booth presentations and online advertising generated the most inquiries about the study. Word of mouth, referral from another study and direct email were the most cost-effective strategies. Not surprisingly, the recruited study population was less ethnically diverse, more affluent and more educated than the background population of pregnant women in Vancouver. A combination of passive and active recruitment techniques were successful for recruiting healthy women in roughly the first trimester of pregnancy (<15 weeks gestation). While a convenience sample of women is suitable for our study questions, additional strategies may be required to recruit a more representative pregnant population in future studies.

The describe the radiologic findings of granulomatous mastitis of the breast. This study included 19 patients (age range: 22 to 56 years; mean 37 years) with 22 lesions that were pathologically confirmed as having granulomatous mastitis. All the patients underwent a breast ultrasonography and 13 patients underwent a mammography. The results of the mammography revealed focal asymmetry (n = 9), multiple ill-defined isodense nodules (n 2), ill-defined nodular density on craniocaudal view (n = 1), and unremarkable finding (n = 1). The sonographic findings included continuous or discontinuous multiple tubular and nodular low echoic lesions (n = 7), ill-defined heterogeneously low echoic lesion (n = 5), irregular-shaped, ill-defined low echoic mass (n = 4), fluid collection with internal floating materials suggesting the presence of an abscess (n = 4), ill-defined heterogeneously low echoic lesion and abscess (n = 1), and multiple ill-defined nodules (n = 1). In the case of granulomatous mastitis, the mammography results indicate a lack of specificity between normal findings and focal asymmetry. The sonographic findings indicate that ill-defined heterogeneously low echoic lesions or irregular shaped, ill-defined low echoic masses are difficult to differentiate from breast cancer. The sonographic findings of abscesses indicate a difficulty in differentiating them from cases of pyogenic mastitis. However, multiple tubular and nodular low echoic lesions, especially with a continuous appearance, should point to granulomatous mastitis, and is helpful in its differential diagnosis and treatment.

Representing and intervening: 'doing' good care in first trimester prenatal knowledge production and decision-making

DEFF Research Database (Denmark)

Schwennesen, Nete; Koch, Lene

2012-01-01

This article investigates processes of knowledge production and decision-making in the practice of the first trimester prenatal risk assessment (FTPRA) at an ultrasound clinic in Denmark. On the basis of ethnographic material and interviews with professionals facilitating FTPRAs in Denmark, we draw...... attention to the active engagement of health professionals in this process. Current professional and policy debate over the use of prenatal testing emphasises the need for informed choice making and for services that provide prospective parents with what is referred to as 'non-directive counselling...... of reducing emotional suffering and supporting a pregnant woman's ability to make meaningful choices on the basis of uncertain knowledge. As such, these practices can be seen as representing another (caring) solution to the problem of paternalism and authoritarian power. In opposition to an ethics aiming...

To determine association, and predictive ability, of first trimester maternal serum pregnancy associated plasma protein A (PAPP-A) with adverse pregnancy outcomes. Searches of Medline, Embase and CINAHL (inception September 2015) for studies including pregnant women with first trimester PAPP-A and assessment of pregnancy outcomes. Study characteristics, quality and results extracted. Meta-analysis of odds ratios (ORs), and likelihood ratios (LRs) and 95% confidence intervals (CI). Thirty-two studies including 175 240 pregnancies. PAPP-A <5th centile had a moderate association with: birth weight <10th centile OR 2.08 (95% CI 1.89-2.29), <5th centile OR 2.83 (95% CI 2.52-3.18); pre-eclampsia OR 1.94 (95% CI 1.63-2.30), preterm birth <37 weeks OR 2.09 (95% CI 1.87-2.33), and composite adverse outcome OR 3.31 (95% CI 1.80-5.11). The predictive ability was poor: Birth weight <10th centile LR + ve 1.96 (95% CI 1.58-2.43), LR-ve 0.93 (95% CI 0.89-0.98); birth weight <5th centile LR + ve 2.65 (95% CI 2.35-2.99), LR-ve 0.85 (95% CI 0.74-0.98); PTB <37 weeks LR + ve 1.84 (95% CI 1.41-2.39), LR-ve 0.92 (95% CI 0.87-0.98). First trimester low maternal serum PAPP-A is associated with adverse pregnancy outcome, but predictive values are poor. Further work should address PAPP-A as a continuous variable in combination with other prognostic markers as a prediction model. © 2016 John Wiley & Sons, Ltd. © 2016 John Wiley & Sons, Ltd.

Sonographic appearance of cervical lymphadenopathy due to infectious mononucleosis in children and young adults

Aim: To depict the grey-scale and Doppler features of cervical lymphadenopathy due to infectious mononucleosis (IM) and to compare the findings with other benign conditions and lymphoma. Materials and methods: One hundred and four patients <30 years old with 138 enlarged lymph nodes (LNs) were enrolled for sonographic analysis. These LNs were grouped as: IM LNs (59 LNs in 30 patients), lymphoma (30 LNs in 30 patients), bacterial lymphadenitis (24 LNs in 20 patients), tuberculosis (TB; 14 LNs in 13 patients), and reactive hyperplasia (11 LNs in 11 patients). Sonographic assessments included shape, echotexture, hilum, border, matting, cystic necrosis, calcification, and vascular pattern. For each sonographic feature, Fisher's exact test was performed to determine whether the difference between IM LNs and any another aetiology were statistically significant. Results: IM LNs tended to be round in shape (69%), heterogeneous in echotexture (61%), absent of echogenic hilum (66%), indistinct margins (80%), bilateral distribution (91%), and matting (83%) [even bilateral matting (66%)], and central hilar vascularity (89.8%). On analysis, bilateral matting had the highest specificity to IM LNs; however, its sensitivity was relatively low. In contrast to IM LNs, TB LNs were more likely to have unilateral matting, cystic necrosis, and calcification. Indistinct margins and decreased echogenicity of the hilum were more frequently seen in IM LNs than in bacterial LNs. Furthermore, central hilar vascularity was a common feature of IM LNs and other benignity, which can distinguish these from lymphoma and TB LNs. Conclusion: Although an individual sonographic feature had considerable overlaps between IM LNs and other aetiologies, the combination of several features may be helpful in the diagnosis of IM

The aims of this study were to evaluate the sonographic findings of patients with hereditary neuropathy with liability to pressure palsies (HNPP) and to examine the correlation between sonographic and electrophysiological findings. Nine patients whose electrophysiological findings indicated HNPP and whose diagnosis was confirmed by genetic analysis were enrolled in the study. The median, ulnar, peroneal, and tibial nerves were evaluated by ultrasonography. We ultrasonographically evaluated 18 median, ulnar, peroneal, and tibial nerves. Nerve enlargement was identified in the median, ulnar, and peroneal nerves at the typical sites of compression. None of the patients had nerve enlargement at a site of noncompression. None of the tibial nerves had increased cross-sectional area (CSA) values. There were no significant differences in median, ulnar, and peroneal nerve distal motor latencies (DMLs) between the patients with an increased CSA and those with a normal CSA. In most cases, there was no correlation between electrophysiological abnormalities and clinical or sonographic findings. Although multiple nerve enlargements at typical entrapment sites on sonographic evaluation can suggest HNPP, ultrasonography cannot be used as a diagnostic tool for HNPP. Ultrasonography may contribute to the differential diagnosis of HNPP and other demyelinating polyneuropathies or compression neuropathies; however, further studies are required.

Sonographers' perceptions of ergonomic and work-related pain problems at work have so far mostly been researched in quantitative studies by questionnaires. There is a need of experience-based research to deepen the knowledge about how sonographers perceive ergonomic problems at work. Therefore, the aim of this qualitative study was to describe sonographers' perceptions of ergonomic problems at work, and their suggestions for improvement strategies. Twenty-two female sonographers were individually interviewed regarding different aspects of their physical working environment. Content analysis was applied. The sonographers perceived different ergonomic problems in their working environment, but to offer patient comfort and to obtain the best possible images were often prioritized over working posture. Echocardiography was considered demanding as the examination is performed with little variation in posture. Ergonomic improvements included reducing the manual handling of the transducer, optimizing the adjustability of equipment, and taking the patient's physique and health into account. As some examinations were perceived to be more ergonomically demanding, variation between examinations was suggested, however, this requires broader skills. Sonography, especially echocardiography is ergonomically demanding but the improvement strategies suggested were perceived useful and applicable.

Aim of this study was to assess the prognostic capability of afamin to predict pregnancy complications. First-trimester screening was consecutively performed in 4948 pregnant women, of whom 474 women developed pregnancy complications [gestational hypertension (n=84), pre-eclampsia (n=30), intrauterine growth restriction (n=107), preterm birth (n=44), and gestational diabetes mellitus (n=209)]. To each woman with pregnancy complications an uncomplicated pregnancy was matched for body mass index. Afamin serum concentrations were measured in 948 pregnant women at the first-trimester screening. Median afamin concentrations were significantly higher in women developing pre-eclampsia or gestational diabetes mellitus when compared to women with uncomplicated pregnancies (76mg/L vs. 65mg/L, p=0.001 and 80mg/L vs. 69mg/L, p65mg/L) was a strong and independent predictor for the development of pre-eclampsia (risk ratio, 24.58; 95%CI, 2.82-214.12; p=0.004) as well as gestational diabetes mellitus (risk ratio, 2.07; 95%CI, 1.33-3.22; p=0.001). In this large nested case-control study increased afamin concentrations were a strong and independent predictor for pre-eclampsia and gestational diabetes mellitus, suggesting a potential role of afamin as predictive marker for pregnancy-related metabolic disorders.

To evaluate the diagnostic value of sonographic irregularities of liver surface in the differentiation of chronic liver disease. Fifty-eight patients with either chronic hepatitis or early stage of liver cirrhosis were examined with 5 MHz linear array transducer by observing the liver surface.We compared the sonographic findings with peritoneoscopic and pathologic findings. Thirty-five patients with smooth surface showed variable pathological results, including chronic active and persistent hepatitis, inactive hepatitis and alcoholic hepatitis without any evidence of cirrhosis. Nineteen patients with micronodules mostly revealed chronic active hepatitis and cirrhosis. All 4 patients with macronodules were proved pathologically ascirrhosis. High resolution ultrasonography(HRUS) showed smooth liver surface in 35 patients(60.3%),micronodular surface in l9(32.8%), and macronodular surface in 4 (6.9%). Twenty-one cases(60.0%) among 35 patients with smooth surface were peritoneoscopically normal and 12 cases(34.3%) showed dimpling surface. However among l9 patients with micronodular surface, only 5 cases(26.3%) showed micronodular surface on peritoneoscopy. while 8 cases(42.l%) showed nracronodular surface and 6 cases(3l.6%) dimpling surface. All 4 patients with macronodulesrevealed peritoneoscopically nracronodular surface. Observation of liver surface by HRUS was useful in predicting the progression of chronic hepatitis to cirrhosis. However, it was not helpful in the differentiation between normal liver and chronic hepatrtrs

Full Text Available Objective. To expand the search for preeclampsia (PE metabolomics biomarkers through the analysis of acylcarnitines in first-trimester maternal serum. Methods. This was a nested case-control study using serum from pregnant women, drawn between 8 and 14 weeks of gestational age. Metabolites were measured using an UPLC-MS/MS based method. Concentrations were compared between controls (n=500 and early-onset- (EO- PE (n=68 or late-onset- (LO- PE (n=99 women. Metabolites with a false discovery rate <10% for both EO-PE and LO-PE were selected and added to prediction models based on maternal characteristics (MC, mean arterial pressure (MAP, and previously established biomarkers (PAPPA, PLGF, and taurine. Results. Twelve metabolites were significantly different between EO-PE women and controls, with effect levels between −18% and 29%. For LO-PE, 11 metabolites were significantly different with effect sizes between −8% and 24%. Nine metabolites were significantly different for both comparisons. The best prediction model for EO-PE consisted of MC, MAP, PAPPA, PLGF, taurine, and stearoylcarnitine (AUC = 0.784. The best prediction model for LO-PE consisted of MC, MAP, PAPPA, PLGF, and stearoylcarnitine (AUC = 0.700. Conclusion. This study identified stearoylcarnitine as a novel metabolomics biomarker for EO-PE and LO-PE. Nevertheless, metabolomics-based assays for predicting PE are not yet suitable for clinical implementation.

Forty percent of women with primary cytomegalovirus (CMV) infections during pregnancy infect their fetuses with complications for the baby varying from mild to severe. How CMV crosses the syncytiotrophoblast, the barrier between maternal blood and fetal tissue in the villous placenta, is unknown. Virus may cross by infection of maternal cells that pass through physical breaches in the syncytiotrophoblast or by direct infection of the syncytiotrophoblast, with subsequent transmission to underlying fetal placental cells. In this study, we show that pure (>99.99%), long-term and healthy (>3 weeks) cultures of syncytiotrophoblasts are permissively infected with CMV. Greater than 99% of infectious progeny virus remained cell associated throughout culture periods up to 3 weeks. Infection of term trophoblasts required a higher virus inoculum, was less efficient, and progressed more slowly than parallel infections of placental and human embryonic lung fibroblasts. Three laboratory strains (AD169, Towne, and Davis) and a clinical isolate from a congenitally infected infant all permissively infected trophoblasts, although infection efficiencies varied. The infection of first trimester syncytiotrophoblasts with strain AD169 occurred at higher frequency and progressed more rapidly than infection of term cells but less efficiently and rapidly than infection of fibroblasts. These results show that villous syncytiotrophoblasts can be permissively infected by CMV but that the infection requires high virus titers and proceeds slowly and that progeny virus remains predominantly cell associated.

To evaluate the diagnostic value of different sonographic methods in hemorrhoids. Forty-two healthy volunteers and sixty-two patients with grades I-IV hemorrhoids received two different sonographic examinations from January 2013 to January 2016 at the First and Second Hospitals of Xinjiang Medical University in a prospective way. We analyzed the ultrasonographic findings of these participants and evaluated the outcomes. Resected grades III and IV hemorrhoid tissues were pathologically examined. The concordance of ultrasonographic results with pathology results was assessed with the Cohen's kappa coefficient. All healthy volunteers and all patients had no particular complications related to sonography. There were no statistically significant differences between the participants regarding age ( P = 0.5919), gender ( P = 0.4183), and persistent symptoms ( P > 0.8692). All healthy control participants had no special findings. However, 30 patients with hemorrhoids showed blood signals around the dentate line on ultrasonography. When grades I and II hemorrhoids were analyzed, there were no significant differences between transrectal ultrasound (TRUS), transperianal ultrasound (TPUS), and transvaginal ultrasound (TVUS) ( P > 0.05). Grades III and IV hemorrhoids revealed blood flow with different directions which could be observed as a "mosaic pattern". In patients with grades III and IV hemorrhoids, the number of patients with "mosaic pattern" as revealed by TRUS, TPUS and TVUS was 22, 12, and 4, respectively. Patients with grades III and IV disease presented with a pathologically abnormal cushion which usually appeared as a "mosaic pattern" in TPUS and an arteriovenous fistula in pathology. Subepithelial vessels of resected grades III and IV hemorrhoid tissues were manifested by obvious structural impairment and retrograde and ruptured changes of internal elastic lamina. Some parts of the Trietz's muscle showed hypertrophy and distortion. Arteriovenous fistulas and

Ultrasound(US) findings of hyperechoic renal medulla in gouty nephropathy were compared with clinical features such as serum uric acid level to evaluate its usefulness in determination of the treatment and prognosis. A retrospective review of US of 36 cases of qouty arthritis was classified into four groups according to the medullary echogenicity (O :normal, grade I: renal medulla as isoechoic as renal cortex, grade II; heterogeneous increased echogenicity of renal medulla than that of renal cortex, grade III: the echogenicity of all renal medulla higher than that of renal cortex with renal contour deformity) which were compared with the serum urate level and associated conditions. Nephrocalcinosis and nephrolithiasis were analyzed through the KUB and the RGB. The degree of hyperechoic renal medulla was related to the level of serum uric acid, and in group IV, six cases of obstructive uropathy (nephrocalcinosis and nephrolithiasis) showed deformed renal contour. Associated conditions such as hypertension, alcoholism, diabetes mellitus and drug abuse were distributed in relation to the degree of hyperechoic renal medullas. US findings of hyperechoic renal mebulla was related with uric acid level in gouty nephropathy and thus could be valuable for treatment decision and prediction of prognosis

Ultrasound(US) findings of hyperechoic renal medulla in gouty nephropathy were compared with clinical features such as serum uric acid level to evaluate its usefulness in determination of the treatment and prognosis. A retrospective review of US of 36 cases of qouty arthritis was classified into four groups according to the medullary echogenicity (O :normal, grade I: renal medulla as isoechoic as renal cortex, grade II; heterogeneous increased echogenicity of renal medulla than that of renal cortex, grade III: the echogenicity of all renal medulla higher than that of renal cortex with renal contour deformity) which were compared with the serum urate level and associated conditions. Nephrocalcinosis and nephrolithiasis were analyzed through the KUB and the RGB. The degree of hyperechoic renal medulla was related to the level of serum uric acid, and in group IV, six cases of obstructive uropathy (nephrocalcinosis and nephrolithiasis) showed deformed renal contour. Associated conditions such as hypertension, alcoholism, diabetes mellitus and drug abuse were distributed in relation to the degree of hyperechoic renal medullas. US findings of hyperechoic renal mebulla was related with uric acid level in gouty nephropathy and thus could be valuable for treatment decision and prediction of prognosis.

Sonographic abnormalities of the achilles and patellar tendons are common findings in athletes, and tendinopathy is a common cause of pain and disability in athletes. However, it is unclear whether the sonographic changes are pathological or adaptive, or if they predict future injury. We undertook a cohort study to determine what sonographic features of the achilles and patellar tendons are consistent with changes as a result of ballet training, and which may be predictive of future development of disabling tendon symptoms. The achilles and patellar tendons of 79 (35 male, 44 female) professional ballet dancers (members of the English Royal Ballet) were examined with ultrasound, measuring proximal and distal tendon diameters and assessing for the presence of hypoechoic change, intratendon defects, calcification and neovascularity. All subjects were followed for 24 months for the development of patellar tendon or achilles-related pain or injury severe enough to require time off from dancing. Sonographic abnormalities were common among dancers, both male and female, and in both achilles and patellar tendons. Disabling tendon-related symptoms developed in 10 dancers and 14 tendons: 7 achilles (3 right, 4 left) and 7 patellar (2 right, 5 left). The presence of moderate or severe hypoechoic defects was weakly predictive for the development of future disabling tendon symptoms (p=0.0381); there was no correlation between any of the other sonographic abnormalities and the development of symptoms. There was no relationship between achilles or patellar tendons' diameter, either proximal or distal, with an increased likelihood of developing tendon-related disability. The presence of sonographic abnormalities is common in ballet dancers, but only the presence of focal hypoechoic changes predicts the development of future tendon-related disability. This suggests that screening of asymptomatic individuals may be of use in identifying those who are at higher risk of developing

Full Text Available Animal embryotoxicity data, and the scarcity of safety data in human pregnancies, have prevented artemisinin derivatives from being recommended for malaria treatment in the first trimester except in lifesaving circumstances. We conducted a meta-analysis of prospective observational studies comparing the risk of miscarriage, stillbirth, and major congenital anomaly (primary outcomes among first-trimester pregnancies treated with artemisinin derivatives versus quinine or no antimalarial treatment.Electronic databases including Medline, Embase, and Malaria in Pregnancy Library were searched, and investigators contacted. Five studies involving 30,618 pregnancies were included; four from sub-Saharan Africa (n = 6,666 pregnancies, six sites and one from Thailand (n = 23,952. Antimalarial exposures were ascertained by self-report or active detection and confirmed by prescriptions, clinic cards, and outpatient registers. Cox proportional hazards models, accounting for time under observation and gestational age at enrollment, were used to calculate hazard ratios. Individual participant data (IPD meta-analysis was used to combine the African studies, and the results were then combined with those from Thailand using aggregated data meta-analysis with a random effects model. There was no difference in the risk of miscarriage associated with the use of artemisinins anytime during the first trimester (n = 37/671 compared with quinine (n = 96/945; adjusted hazard ratio [aHR] = 0.73 [95% CI 0.44, 1.21], I2 = 0%, p = 0.228, in the risk of stillbirth (artemisinins, n = 10/654; quinine, n = 11/615; aHR = 0.29 [95% CI 0.08-1.02], p = 0.053, or in the risk of miscarriage and stillbirth combined (pregnancy loss (aHR = 0.58 [95% CI 0.36-1.02], p = 0.099. The corresponding risks of miscarriage, stillbirth, and pregnancy loss in a sensitivity analysis restricted to artemisinin exposures during the embryo sensitive period (6-12 wk gestation were as follows: aHR = 1

Aim: To assess reproducibility of estimating gestational age (GA) of foetus using femur length (FL), biparietal diameter (BPD) and abdominal circumference (AC) within experienced and inexperienced sonographers and between the two. Patients and methods: Two sets of GA estimates each were obtained for FL, BPD and AC by the two observers in 20 normal singleton foetuses. The first estimates for the three biometric parameters were made by the experienced sonographer. Subsequently, the inexperienced sonographer, blind to the estimates of the first observer obtained his own estimates for the same biometric parameters. After a time interval of ten minutes the process was repeated for the second set of GA estimates. All the gestational age estimates were made following standard protocol. Statistical analysis was performed by Pearson's and intraclass correlations, coefficient of variation and Bland–Altman plots. Statistical inferences were drawn at p < 0.05. Results: The Pearson's and intraclass correlations of between GA estimates within and between both observers from measurement of FL, BPD and AC were very high and statistically significant (p < 0.05). Coefficient of variation for duplicate measurements for GA estimates within observers and between observers were quite negligible. Between observers, the first and second GA estimates from FL measurements showed the least variation. Estimates from BPD and AC measurements showed greater degree of variation between the observers. Conclusion: Reproducibility of GA estimation using FL, BPD and AC within experienced and inexperienced sonographers and between the two was excellent. Therefore, a fresh Nigerian radiography graduate with adequate exposure in obstetric ultrasound can correctly determine the gestational age of foetus in routine obstetric ultrasound without supervision

To evaluate prenatal ultrasonographic findings of limb-body wall complex and to correlate them with autopsy findings. From October 1995 to June 2000, a retrospectively review of prenatal ultrasonography (US) of 11 patients with pathologically proven limb-body wall complex was done. US findings were then compared with autopsy findings. Prenatal ultrasonography revealed thoraco-abdominoschists (n=7.64%), kyphoscoliosis (n=7.64%), cranial defect (n=5.45%), limb defect (n=4.36%), facial defect (n=1.10%), amniotic band (n=5.45%), and umbilical cord anomaly (n=3.27%). Meanwhile, autopsy findings showed thoraco-abdominoschisis (n=8.72%), limb defect (n=7.64%), facial defect (n=7.64%), kyphoscoliosis (n=5.45%), cranial defect (n=5.45%), amniotic band (n=5.45%) and umbilical cord anomaly (n=4.36%). The most common ultrasonography features of limb-body wall complex were thoraco-abdominoschisis and kyphoscoliosis while the thoraco-abdominoschisis and limb defects were the most frequent findings at autopsy.

Accurate assessment of thyroid function during pregnancy is critical, for initiation of thyroid hormone therapy, as well as for adjustment of thyroid hormone dose in hypothyroid cases. We evaluated pregnant women who had no past history of thyroid disorders and studied their thyroid function in each trimester. 86 normal pregnant women in the first trimester of pregnancy were selected for setting reference intervals. All were healthy, euthyroid and negative for thyroid peroxidase antibody (TPOAb). These women were serially followed throughout pregnancy. 124 normal nonpregnant subjects were selected for comparison. Thyrotropin (TSH), free thyroxine (FT4), free triiodothyronine (FT3) and anti-TPO were measured using Roche Elecsys 1010 analyzer. Urinary iodine content was determined by simple microplate method. The 2.5th and 97.5th percentiles were calculated as the reference intervals for thyroid hormone levels during each trimester. SPSS (version 14.0, SPSS Inc., Chicago, IL, USA) was used for data processing and analysis. The reference intervals for the first, second and third trimesters for the following parameters: TSH 0.09-6.65, 0.51-6.66, 0.91-4.86 µIU/mL, FT4 9.81-18.53, 8.52-19.43, 7.39-18.28 pM/L and FT3 3.1-6.35, 2.39-5.12, 2.57-5.68 pM/L respectively. Thyroid hormone concentrations significantly differed during pregnancy at different stages of gestation. The pregnant women in the study had median urinary iodine concentration of 150-200 µg/l during each trimester. The trimester-specific reference intervals for thyroid tests during pregnancy have been established for pregnant Indian women serially followed during pregnancy using 2.5th and 97.5th percentiles.

To determine the performance of third trimester ultrasound in women with suspected fetal macrosomia. We performed a retrospective cohort study of fetal ultrasounds from January 2004 to December 2014 with estimated fetal weight (EFW) between 4000 and 5000 g. We determined accuracy of birth weight prediction for ultrasound performed at less than and greater than 38 weeks, accounting for diabetic status and time between ultrasound and delivery. There were 405 ultrasounds evaluated. One hundred and twelve (27.7%) were performed at less than 38 weeks, 293 (72.3%) at greater than 38 weeks, and 91 (22.5%) were performed in diabetics. Sonographic identification of EFW over 4000 g at less than 38 weeks was associated with higher correlation between EFW and birth weight than ultrasound performed after 38 weeks (71.5 versus 259.4 g, p < .024). EFW to birth weight correlation was within 1.7% of birth weight for ultrasound performed less than 38 weeks and within 6.5% of birth weight for ultrasound performed at greater than 38 weeks. Identification of EFW with ultrasound performed less than 38 weeks has greater reliability of predicting fetal macrosomia at birth than measurements performed later in gestation. EFW to birth weight correlation was more accurate than previous reports.

To correlate the sonographic finding of ill-defined fibroadenoma with the histopathologic findings. Sonographic finding of forty nine surgically proven fibroadenomas were retrospectively correlated with histopathologic findings. We evaluated sonographic findings including the margin, shape, size and the echotexture of fibroadenoma. The histopathologic glandular structure, stromal type of fibroadenoma, type of the surrounding breast tissue and presence of interdigitation between fibroadenoma and the surrounding breast tissue were pathologically reviewed and analyzed statistically. Breast sonography of fibroadenomas demonstrated well-defined margin in 28 (57%) and ill-defined margin in 21 (43%) among 49 lesions. Histopathologically, the glandular structure and type of the surrounding breast tissue were not significantly different between well-defined and ill-defined fibroadenomas. The stromal type of fibroadenoma was sclerotic in 8 (29%) well-defined fibroadenomas while sclerotic in 15 (72%) of 21 ill-defined fibroadenomas,showing difference with a statistical significance between well-defined and ill-defined fibroadenomas (p<0.05). Twenty (71%) of 28 fibroadenomas with well-defined sonographic margins showed well-defined border between mass and the surrounding breast tissue, pathologically. Meanwhile, twenty (95%) of 21 fibroadenomas with ill-defined sonographic margins demonstrated interdigitation of the surrounding breast tissue and mass, exhibiting a statistical significance (p<0.005). Ill-defined margins of fibroadenomas on sonography represent the interdigitation of the surrounding breast tissue with a mass and is seen in the sclerotic stromal type of fibroadenomas.

Ultrasonography was performed prospectively in 20 patients who were undergoing continuous ambullatory peritoneal dialysis for evaluation of complications. We examined the abdominal wall along the course of catheter and the peritoneal cavity with special attention to the dialysate distribution, dialysate echogenecity, thickness of the peritoneum small bowel distribution and the position of the catheter tip. Peritonitis was the most common complication (n=7); sonographic findings were small bowel adhesion (n=5) multiseptated ascites(n=1), peritoneal thickening(n=4), and tunnel infection(n=1) and exith site infection(n=1). Our initial experience suggests that ultrasonography is useful for diagnosis of complications and monitoring of patient during long term peritoneal dialysis

Full Text Available Medical students must understand the principles of ultrasonography (US, because US examinations are an important component of patient care in clinical practice. Pocket-sized ultrasound devices have the benefits of accessibility and ease of use. The primary objective of the present study was to evaluate the educational value of these devices in terms of improving medical student interest and understanding of US and sonographic anatomy.We added a US training program comprised of a self-study learning module and a hands-on training session to a two-week block curriculum of medical imaging for first year medical students (n = 40. Multiple pocket-sized US devices were used on a small-group basis during a single afternoon. Students were asked to complete a questionnaire before and after the US training session; these two questionnaires contained 6 and 10 questions, respectively, which were rated by students using a five-point Likert scale. In addition, understanding of sonographic anatomy was tested before and after the training program.Forty students completed the two questionnaires and the anatomy-related tests. Students found the program educationally valuable (4.37 ± 0.54 of 5 and reported that US practice was useful for improving their understanding of the principles of US examinations (4.23 ± 0.66 of 5 and sonographic anatomy (4.40 ± 0.55 of 5. Overall confidence at performing US examinations and understanding of sonographic anatomy were significantly increased after US training (increased overall confidence score, 1.87 ± 0.91 and improvement in sonographic anatomy score, 6.55 ± 1.55, p values < 0.001.US training using pocket-sized ultrasound devices was found to be educationally valuable for medical students in terms of improving understanding of US principles and familiarizing students with sonographic anatomy.

To evaluate the associations between adiponectin levels and 1) the risk of developing gestational diabetes mellitus (GDM), and 2) insulin resistance/sensitivity, β-cell function, and compensation indices in a prospective cohort representative of the general population of pregnant women. We performed anthropometric measurements and collected blood samples at 1st (6-13 weeks) and 2nd (24-28 weeks) trimesters. Diagnosis of GDM was made at 2nd trimester based on a 75-g oral glucose tolerance test (International Association of the Diabetes and Pregnancy Study Groups criteria). Insulin was measured (ELISA; Luminex) to estimate homeostasis model assessment of insulin resistance (HOMA-IR), β-cell function (HOMA-B), insulin sensitivity (Matsuda index), insulin secretion (AUC(insulin/glucose)), and β-cell compensation (insulin secretion sensitivity index-2). Adiponectin was measured by radioimmunoassay. Among the 445 participants included in this study, 38 women developed GDM. Women who developed GDM had lower 1st-trimester adiponectin levels (9.67 ± 3.84 vs. 11.92 ± 4.59 µg/mL in women with normal glucose tolerance). Lower adiponectin levels were associated with higher risk of developing GDM (OR, 1.12 per 1 µg/mL decrease of adiponectin levels; P = 0.02, adjusted for BMI and HbA1c at 1st trimester). Adiponectin levels at 1st and 2nd trimesters were associated with HOMA-IR (both: r = -0.22, P insulin/glucose). Pregnant women with lower adiponectin levels at 1st trimester have higher levels of insulin resistance and are more likely to develop GDM independently of adiposity or glycemic measurements.

Full Text Available Trimester in Acquabox (2010 is a live performance by Czech-British artist Helena Eflerová, which was originally exhibited at the Para Haus exhibition in São Paulo, Brazil. The audience is invited to view a narrative journey representing a metaphor of the foetus' development in the womb, and to share the experience with the performer, exploring an underwater weightless habitat. This collective experience of viewing such an intimate performance proposes questions around the personal experience of early childhood and motherhood. It questions the development of the foetus, its capacity of memory, its happy and traumatic experiences in the womb, and the after-effect on postnatal life. http://podcast.ulcc.ac.uk/accounts/BirkbeckCollege/mamsie/trimester_in_acquabox.mov

Sonographic detection of intrarenal and intraarterial fungus balls in a preterm infant due to systemic candidiasis

Shortly after birth a preterm infant suffering from aspiration syndrome and subsequent Pseudomonas aeruginosa sepsis showed signs of renal insufficiency and mycotic infection: Yeast cells were identified in several urinalyses; there was also an increasing anti-Candida IgM antibody titer. At the same time sonographic examinations revealed an increasing echogenicity of the renal cortex and echogenic masses of variable size which did not cause acoustic shadows in both enlarged kidneys. A few days later, we found a right-sided hydronephrosis caused by an intraureteric prevesical mass of equal echogenicity. As we could observe sonographically, the aggressive antimycotic therapy was successful. Eleven weeks later there were signs of cardiac insufficiency. An angiographically demonstrated filling defect within the pulmonary artery showed the same sonographic findings as the previously found intrarenal masses. The baby underwent embolectomy and recovered. The thrombotic material contained yeast cells giving evidence of systemic Candidasis. Provided appropriate equipment is available, ultrasound today is an excellent non-invasive screening and followup method not only for echoencephalography, but also for more complicated neonatologic problems as seen here. The detailed observation of a changing echogenicity of the renal cortex and pelvis is important and often allows a decisive diagnostic clue before other radiological methods become conclusive.

Background. Tyrosinemia relates to a deficiency of fumarylacetoacetate hydrolase and presents early in life with central nervous system and liver abnormalities. Renal function is often impaired. Little is known about the architecture and function of the kidneys. Objective. Imaging changes on US and CT are compared to the function of the kidneys in children with tyrosinemia, and followed after liver transplantation. Materials and methods. Renal sonography, CT and renal function tests in 32 children were reviewed. Renal length, volume, echogenicity and nephrocalcinosis were evaluated. Renal function was assessed by glomerular filtration rate, and the presence of aminoaciduria, acidosis and calciuria. Seventeen children had open renal biopsy during time of liver transplantation. Histology was reviewed. Statistical analyses relating renal structure to function were performed, and repeated after transplantation. Results. The kidneys were enlarged (47%), hyperechogenic (47%) and showed nephrocalcinosis (16%). There was delayed excretion of contrast medium at CT in 64%. Aminoaciduria was present in 82% of children, hypercalciuria in 67%, tubular acidosis in 59%, and low GFR in 48%. Delayed excretion of contrast was associated with low GFR (P<0.05). Renal biopsies showed dilated tubules (81%), interstitial fibrosis (56%), glomerulosclerosis (56%) and tubular atrophy (56%). During a mean observation period of 3 years following liver transplantation, GFR improved in 50 %, tubular acidosis in 50% and hypercalciuria in 70%. No change was noted in renal size or sonographic architecture. Conclusion. Renal architecture and function are abnormal in the majority of children with tyrosinemia. Liver transplantation improves renal function in about 50% of patients, but abnormal renal size and architecture persist. (orig.)

A review of the current state of knowledge is made on sonographic evaluation of penile in patients with erectile dysfunction. This sonography is developed with high resolution ultrasound on gray scale, combined with color Doppler ultrasonography; which the arteries of penile are examined before and during the erection. The penile ultrasonography has meant an important tool in the evaluation of specific patients who have submitted erectile dysfunction, particularly, in those with record of trauma and history of Peyronie's disease. In addition, through a sonographic evaluation has permitted to prove manifestations of the pathophysiological phenomena of the patient in order to establish their classification and guide their treatment [es

Approximately 21 days after an abortion, ovulation occurs in 50 % of women. Installation of an IUD directly after induced or spontaneous abortion offers immediate contraceptive protection. The purpose of the present study was to weigh up contraceptive safety and adverse reactions of IUD inserted directly after first-trimester abortion under general or paracervical anesthesia as against the fitting of IUD in the days of the next menstrual cycle without anesthesia. During the period May 1987 to October 2010, 73 women (Group A) underwent an immediate post-abortion insertion IUD after a first-trimester spontaneous or induced abortion under general or local paracervical anesthesia and 69 participants (Group B) received IUD during the next menstrual cycle without anesthesia. Questionnaires were completed by all the women of the study with respect to the effects of IUD. The women were examined every 3 months for 1 year after the fitting of the IUD in the out-patient department of the University Obstetrics Gynecological Department of Alexandroupolis, Democritus University of Thrace, Greece. The demographic characteristics of the women of the two groups were similar. The age of the women ranged between 19 and 44 years, while 61.98 % were women with one or two children and 38.02 % were women with three or more children. During the first menstrual cycles, with the exception of vaginal hemorrhages (5 %) and adnexitis (1 %), no serious adverse reactions were noted. During the transvaginal ultrasonography checks in both groups, no observation was made of any dislocation of the IUD, except for two cases in the subgroup of those women with paracervical anesthesia and one case in the women of Group B. As concerns the questionnaire with regard to the women's subjective evaluation of IUD, satisfactory answers were given. There were no differences between the two groups either with respect to the security of the supplied contraceptive methods or to the development of side effects.

Transrectal sonography of prostate was sensitive to textural changes produced by both benign prostate hyperplasia (BPH) and prostate cancers. During recent 4 years, twenty cases of BPH and twenty cases of prostate cancers proven histologically were analyzed in their sonographic features, retrospectively, by using transrectal prostate sonography and suprapubic prostate sonography. The results were as follows: 1. Mean weights of BPH and prostate cancers was 40.4g and 47.6g, respectively. 2. Sonographic features of BPH revealed isoechogenecity in 11 cases, homogeneity in 18 cases, well defined capsular margins in 19 cases, and calcification in 16 cases. 3. Sonographic features of prostate cancers revealed mixed echogenecity in 14 cases, inhomogeneity in 15 cases, poorly defined capsular margin in 14 cases, and calcifications in 13 cases. 4. Authors concluded that prostate sonography were valuable diagnostic modality in the differentiation of BPH and prostate cancers.

Objective To identify socio-demographic factors associated with presenting for abortion services past the gestational age (GA) limit (12 weeks), and thus not receiving services, in Mexico City’s public sector first trimester abortion program. Methods We used clinical data from four high volume sites in the Interrupción Legal de Embarazo (ILE) program, 2007–2015. We used descriptive statistics to quantify the proportion of women who did not receive an abortion due to presenting past the gestational age limit. We used multivariable logistic regression to identify associations between women’s characteristics and presenting past the GA limit and calculated predicted probabilities of late presentation for key characteristics. Results Our sample included 52,391 women, 8.10% (n = 4,246) of whom did not receive abortion services due to presenting past the GA limit. Adolescents (12–17) made up 8.69% of the total sample and 13.40% of those presenting past the GA limit (p = 40 years’ old respectively). Women living in Mexico City and with higher levels of education had lower odds of presenting past the GA limit, and there was an educational gradient across all age groups. In the multivariable predicted probability models, adolescents at every level of education have significantly higher probabilities of not receiving an abortion due to presenting past the gestational age limit compared with adults (among women with a primary education: 11.75% adolescents vs. 9.02–4.26% across adult age groups). Conclusions Our results suggest that continued efforts are needed to educate women, especially younger and less educated women, about early pregnancy recognition. In addition, all women need information about the availability of first trimester legal abortion to ensure timely access to abortion services. PMID:29414987
