Abstract
OBJECTIVES To determine the rate of recurrent Cesarean scar pregnancy (CSP) in our clinical practices and to evaluate whether the mode of treatment of a CSP is associated with the risk of recurrent CSP, as well as to review the published literature on recurrent CSP. METHODS We performed a retrospective search of our six obstetric and gynecological departmental ultrasound databases for all CSPs and recurrent CSPs between 2010 and 2019. We extracted various data, including number of CSPs with follow-up, number of cases attempting and number achieving pregnancy following treatment of CSP and number of recurrent CSPs, as well as details of the treatment of the original CSP. After analyzing the clinical data, we evaluated whether the mode of treatment terminating the previous CSP was associated with the risk of recurrent CSP. We also performed a PubMed search for: 'recurrent Cesarean scar pregnancy' and 'recurrent Cesarean scar ectopic pregnancy'. Articles were reviewed for year of publication, and extraction and analysis of the same data as those obtained from our departmental databases were performed. RESULTS Our database search identified 252 cases of CSP. The overall rate of clinical follow-up ranged between 71.4% and 100%, according to treatment site (mean, 90.9%). Among these, 105 women had another pregnancy after treatment of the previous CSP. Of these, 36 (34.3%) pregnancies were recurrent CSP, with 27 women having a single recurrence and three women having multiple recurrences, one with two, one with three and one with four. We did not find any particular single or combination treatment mode terminating the previous CSP to be associated with recurrent CSP. The literature search identified 17 articles that yielded sufficient information for us to evaluate their reported prevalence of recurrent CSP. These reported 1743 primary diagnoses of CSP, of which 944 had reliable follow-up. Data were available for 489 cases that attempted to conceive again after treatment of a previous CSP, and on the 327 pregnancies achieved. Of these, 67 (20.5%) were recurrent CSP. CONCLUSIONS On the basis of our pooled clinical data and review of the literature, recurrent CSP is apparently more common than was previously assumed based upon mostly single-case reports or series with few cases. This should be borne in mind when counseling patients undergoing treatment for CSP regarding their risk of recurrence. We found no obvious causal relationship or association between the type of treatment of the previous CSP and recurrence of CSP. Patients who become pregnant after treatment of a CSP should be encouraged to have an early (5-7-week) first-trimester transvaginal scan to determine the location of the gestation. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
OBJECTIVES To explore whether early first-trimester ultrasound can predict the third-trimester sonographic stage of placenta accreta spectrum (PAS) disorder and to elucidate whether combining first-trimester ultrasound findings with the sonographic stage of PAS disorder can stratify the risk of adverse surgical outcome in women at risk for PAS disorder. METHODS This was a retrospective analysis of prospectively collected data from women with placenta previa, and at least one previous Cesarean delivery (CD) or uterine surgery, for whom early first-trimester (5-7 weeks' gestation) ultrasound images could be retrieved. The relationship between the position of the gestational sac and the prior CD scar was assessed using three sonographic markers for first-trimester assessment of Cesarean scar (CS) pregnancy, reported by Calí et al. (crossover sign (COS)), Kaelin Agten et al. (implantation of the gestational sac on the scar vs in the niche of the CS) and Timor-Tritsch et al. (position of the center of the gestational sac below vs above the midline of the uterus), by two different examiners blinded to the final diagnosis and clinical outcome. The primary aim of the study was to explore the association between first-trimester ultrasound findings and the stage of PAS disorder on third-trimester ultrasound. Our secondary aim was to elucidate whether the combination of first-trimester ultrasound findings and sonographic stage of PAS disorder can predict surgical outcome. Logistic regression analysis and area under the receiver-operating-characteristics curve (AUC) were used to analyze the data. RESULTS One hundred and eighty-seven women with vasa previa were included. In this cohort, 79.6% (95% CI, 67.1-88.2%) of women classified as COS-1, 94.4% (95% CI, 84.9-98.1%) of those with gestational-sac implantation in the niche of the prior CS and 100% (95% CI, 93.4-100%) of those with gestational sac located below the uterine midline, on first-trimester ultrasound, were affected by the severest form of PAS disorder (PAS3) on third-trimester ultrasound. On multivariate logistic regression analysis, COS-1 (odds ratio (OR), 7.9 (95% CI, 4.0-15.5); P < 0.001), implantation of the gestational sac in the niche (OR, 29.1 (95% CI, 8.1-104); P < 0.001) and location of the gestational sac below the midline of the uterus (OR, 38.1 (95% CI, 12.0-121); P < 0.001) were associated independently with PAS3, whereas parity (P = 0.4) and the number of prior CDs (P = 0.5) were not. When translating these figures into diagnostic models, first-trimester diagnosis of COS-1 (AUC, 0.94 (95% CI, 0.91-0.97)), pregnancy implantation in the niche (AUC, 0.92 (95% CI, 0.89-0.96)) and gestational sac below the uterine midline (AUC, 0.92 (95% CI, 0.88-0.96)) had a high predictive accuracy for PAS3. There was an adverse surgical outcome in 22/187 pregnancies and it was more common in women with, compared to those without, COS-1 (P < 0.001), gestational-sac implantation in the niche (P < 0.001) and gestational-sac position below the uterine midline (P < 0.001). On multivariate logistic regression analysis, third-trimester ultrasound diagnosis of PAS3 (OR, 4.3 (95% CI, 2.1-17.3)) and first-trimester diagnosis of COS-1 (OR, 7.9 (95% CI, 4.0-15.5); P < 0.001), pregnancy implantation in the niche (OR, 29.1 (95% CI, 8.1-79.0); P < 0.001) and position of the sac below the uterine midline (OR, 6.6 (95% CI, 3.9-16.2); P < 0.001) were associated independently with adverse surgical outcome. When combining the sonographic coordinates of the three first-trimester imaging markers, we identified an area we call high-risk-for-PAS triangle, which may enable an easy visual perception and application of the three methods to prognosticate the risk for CS pregnancy and PAS disorder, although it requires validation in large prospective studies. CONCLUSIONS Early first-trimester sonographic assessment of pregnancies with previous CD can predict reliably ultrasound stage of PAS disorder. Combination of findings on first-trimester ultrasound with second- and third-trimester ultrasound examination can stratify the surgical risk in women affected by a PAS disorder.

Abstract
OBJECTIVE To describe and evaluate the utility of a new sonographic microcystic pattern, which is typical of borderline ovarian tumor (BOT) papillary projections, solid component(s) and/or septa, as a new ultrasound marker that is capable of distinguishing BOT from other adnexal masses, and to present/obtain histologic confirmation. METHODS In this retrospective study, we identified women with a histologic diagnosis of BOT following surgical resection who had undergone preoperative transvaginal ultrasound (TVS) examination. All images were reviewed for presence or absence of thin-walled, fluid-filled cluster(s) of 1-3-mm cystic formations, associated with solid component(s), papillary projections and/or septa. From the same cases, histopathologic slides of each BOT were examined for presence of any of these microcystic features which had been identified on TVS. To confirm that the microcystic TVS pattern is unique to BOTs, we also selected randomly from our ultrasound and surgical database 20 cases of epithelial ovarian cancer and 20 cases of benign cystadenoma, for review by the same pathologists. To confirm the novelty of our findings, we searched PubMed for literature published in the English language between 2010 and 2018 to determine whether the association between microcystic tissue pattern and BOT has been described previously. RESULTS Included in the final analysis were 62 patients (67 ovaries) with preoperative TVS and surgically confirmed BOT on pathologic examination. The mean patient age at surgery was 39.8 years. The mean BOT size at TVS was 60.7 mm. Of the 67 BOTs, 47 (70.1%) were serous, 15 (22.4%) were mucinous and five (7.5%) were seromucinous. We observed on TVS a microcystic pattern in the papillary projections, solid component(s) and/or septa in 60 (89.6%) of the 67 BOTs, including 46 (97.9%) of the 47 serous BOTs, 11 (73.3%) of the 15 mucinous BOTs and three (60.0%) of the five seromucinous BOTs. On microscopic evaluation, 60 (89.6%) of the 67 samples had characteristic 1-3-mm fluid-filled cysts similar to those seen on TVS. In seven cases there was a discrepancy between sonographic and histologic observation of a microcystic pattern. The 20 cystadenomas were mostly unilocular and/or multilocular and largely avascular. None of them or the 20 epithelial ovarian malignancies displayed microcystic characteristics, either on TVS or at histology. On review of 23 published articles in the English medical literature, containing 163 sonographic images of BOT, we found that, while all images contained it, there was no description of the microcystic tissue pattern. CONCLUSION We report herein a novel sonographic marker of BOT, a 'microcystic pattern' of BOT papillary projections, solid component(s) and/or septa. This was seen in the majority of both serous and mucinous BOT cases. Importantly, based on comparison of sonographic images and histopathology of benign entities and malignancies, the microcystic appearance seems to be unique to BOTs. No similar description has been published previously. Utilization of this new marker should help to identify BOT correctly, discriminating it from ovarian cancer and benign ovarian pathology, and should ensure appropriate clinical and surgical management.

Abstract
OBJECTIVES The primary aim of this systematic review was to ascertain whether ultrasound signs suggestive of abnormally invasive placenta (AIP) are present in the first trimester of pregnancy. Secondary aims were to ascertain the strength of association and the predictive accuracy of such signs in detecting AIP in the first trimester. METHODS An electronic search of MEDLINE, EMBASE, CINAHL and Cochrane databases (2000-2016) was performed. Only studies reporting on first-trimester diagnosis of AIP that was subsequently confirmed in the third trimester either during operative delivery or by pathological examination were included. Meta-analysis of proportions, random-effects meta-analysis and hierarchical summary receiver-operating characteristics curve analysis were used to analyze the data. RESULTS Seven studies, involving 551 pregnancies at high risk of AIP, were included. At least one ultrasound sign suggestive of AIP was detected in 91.4% (95% CI, 85.8-95.7%) of cases with confirmed AIP. The most common ultrasound feature in the first trimester of pregnancy was low implantation of the gestational sac close to a previous uterine scar, which was observed in 82.4% (95% CI, 46.6-99.8%) of cases. Anechoic spaces within the placental mass (lacunae) were observed in 46.0% (95% CI, 10.9-83.7%) and a reduced myometrial thickness in 66.8% (95% CI, 45.2-85.2%) of cases affected by AIP. Pregnancies with a low implantation of the gestational sac had a significantly higher risk of AIP (odds ratio, 19.6 (95% CI, 6.7-57.3)), with a sensitivity and specificity of 44.4% (95% CI, 21.5-69.2%) and 93.4% (95% CI, 90.5-95.7%), respectively. CONCLUSIONS Ultrasound signs of AIP can be present during the first trimester of pregnancy, even before 11 weeks' gestation. Low anterior implantation of the placenta/gestational sac close to or within the scar was the most commonly seen early ultrasound sign suggestive of AIP, although its individual predictive accuracy was not high.

Abstract
Understanding how the gut microbiota is affected by diarrhea episodes may help explain alterations in intestinal function among children in low-income settings. This study examined the composition of the gut microbiome of Nicaraguan children both during diarrhea episodes and while free of diarrhea for at least 2 months. Relative abundances of bacterial taxa, phylogenetic diversity, and species richness were determined by 16S amplicon sequencing and compared between paired diarrhea and recovery samples. A total of 66 stools were provided by 25 children enrolled in a 1-year cohort study of diarrhea etiologies. Children in our cohort had a mean age of 21.9 months; 64% were breast-fed, and 10% had received an antibiotic during the diarrhea episode. Overall, phylogenetic diversity and species richness did not differ significantly between diarrhea and recovery stools. However, of children who had a bacterial enteropathogen detected in any diarrhea stool, none experienced an increase in phylogenetic diversity in recovery, whereas of those in whom no bacterial enteropathogens were detected in their diarrhea stool(s), 59% experienced an increase in phylogenetic diversity in recovery (P = 0.008). This preliminary study suggests that recovery of the gut microbiota after a diarrhea episode may take longer time than previously thought and may be pathogen specific.

Abstract
OBJECTIVE To demonstrate the efficacy of placement and inflation of Foley balloon catheters prophylactically to prevent, or as an adjuvant therapy to control, bleeding in women undergoing treatment for Cesarean scar pregnancy (CSP) or cervical pregnancy (CxP). METHODS This was a retrospective study of 18 women with either CSP (n = 16) or CxP (n = 2), who underwent Foley balloon catheter placement under continuous transvaginal or transabdominal ultrasound guidance to prevent or manage bleeding following treatment, which in most cases comprised local (intragestational sac) and intramuscular (IM) methotrexate (MTX) injections. In eight cases, the balloon catheter was placed immediately following local and/or IM MTX treatment, either because of bleeding or prophylactically; in eight cases, the catheter was placed as part of a two-step protocol, with patients first treated with local and IM MTX injection, then suction aspiration on Day 4 or 5, followed by planned insertion of a balloon catheter; in one patient the balloon was placed on Day 21 after local and IM MTX treatment, due to sudden bleeding; and in one case of a heterotopic pregnancy, one intrauterine and one cervical, the balloon was placed due to severe bleeding. Human chorionic gonadotropin (hCG) levels were evaluated weekly following MTX injection. RESULTS Gestational ages at balloon placement ranged between 5 and 12 + 2 weeks. All embryos/fetuses, with the exception of the cervical heterotopic one, had heart activity and catheter placement was well-tolerated by all women. The balloon tamponade effectively reduced or prevented maternal vaginal bleeding in all except one patient; this woman had a heterotopic CxP and required abdominal robotic cerclage to control the bleeding. Catheters were kept in place for a mean of 3.6 (range, 1-6) days. hCG levels returned to low or zero levels within 19-82 days following MTX injection. Fifteen women required antibiotic treatment following the procedure. One woman with CSP developed an arteriovenous malformation requiring uterine artery embolization. CONCLUSION Ultrasound-guided placement and inflation of Foley balloon catheters was easy to perform and well-tolerated by patients undergoing treatment for CSP or CxP, and successfully prevented or helped in the management of bleeding complications. Based on our experience and previous publications we suggest having the option of balloon catheter insertion available when local treatment of CSP or CxP is undertaken.

Abstract
OBJECTIVE To provide further sonographic, clinical and histological evidence that Cesarean scar pregnancy (CSP) is a precursor to and an early form of second- and third-trimester morbidly adherent placenta (MAP). METHODS This is a report of 10 cases of CSP identified early, in which the patients decided to continue the pregnancy, following counseling that emphasized the possibility of both significant pregnancy complications and a need for hysterectomy. Pregnancies were followed at 2-4-week intervals with ultrasound scans and customary monitoring. The aim was for patients to reach near term or term and then undergo elective Cesarean delivery and, if necessary, hysterectomy. Charts, ultrasound images, operative reports and histopathological examinations of the placentae were reviewed. RESULTS The ultrasound diagnosis of CSP was made before 10 weeks. By the second trimester, all patients exhibited sonographic signs of MAP. Nine of the 10 patients delivered liveborn neonates between 32 and 37 weeks. In the tenth pregnancy, progressive shortening of the cervix and intractable vaginal bleeding prompted termination, with hysterectomy, at 20 weeks. Two other patients in the cohort had antepartum complications (bleeding at 33 weeks in one case and contractions at 32 weeks in the other). All patients underwent hysterectomy at the time of Cesarean delivery, with total blood loss ranging from 300 to 6000 mL. Placenta percreta was the histopathological diagnosis in all 10 cases. CONCLUSION The cases in this series validate the hypothesis that CSP is a precursor of MAP, both sharing the same histopathology. Our findings provide evidence that can be used to counsel patients with CSP, to enable them to make an informed choice between first-trimester termination and continuation of the pregnancy, with its risk of premature delivery and loss of uterus and fertility.

Abstract
OBJECTIVE To determine, by evaluation of histological slides, images and descriptions of early (second-trimester) placenta accreta (EPA) and placental implantation in cases of Cesarean scar pregnancy (CSP), whether these are pathologically indistinguishable and whether they both represent different stages in the disease continuum leading to morbidly adherent placenta in the third trimester. METHODS The database of a previously published review of CSP and EPA was used to identify articles with histopathological descriptions and electronic images for pathological review. When possible, microscopic slides and/or paraffin blocks were obtained from the original researchers. We also included from our own institutions cases of CSP and EPA for which pathology specimens were available. Two pathologists examined all the material independently and, blinded to each other's findings, provided a pathological diagnosis based on microscopic appearance. Interobserver agreement in diagnosis was determined. RESULTS Forty articles were identified, which included 31 cases of CSP and 13 cases of EPA containing histopathological descriptions and/or images of the pathology. We additionally included six cases of CSP and eight cases of EPA from our own institutions, giving a total of 58 cases available for histological evaluation (37 CSP and 21 EPA) containing clear definitions of morbidly adherent placenta. In the 29 cases for which images/slides were available for histopathological evaluation, both pathologists attested to the various degrees of myometrial and/or scar tissue invasion by placental villi with scant or no intervening decidua, consistent with the classic definition of morbidly adherent placenta. Based on the reviewed material, cases with a diagnosis of EPA and those with a diagnosis of CSP showed identical histopathological features. Interobserver correlation was high (kappa = 0.93). CONCLUSIONS EPA and placental implantation in CSP are histopathologically indistinguishable and may represent different stages in the disease continuum leading to morbidly adherent placenta in the third trimester.

Abstract
Proximal femoral focal deficiency (PFFD) represents a rare and complex deformity manifested by hypoplasia of a variable portion of the femur with shortening of the entire limb. The condition may be unilateral or bilateral and is often associated with other congenital anomalies. Recent technological advances in ultrasound imaging offer the opportunity to detect an increasing number of rare skeletal malformation syndromes whose correct diagnosis is essential for adequate counseling and management of the pregnancy. We report a case of fetal non-familial PFFD diagnosed prenatally using two-dimensional and three-dimensional images. Clinical findings, differential diagnosis and management of this rare skeletal dysplasia are discussed and a review of the recent literature is given.

Abstract
Sorafenib is a new drug, multikinase inhibitor, which has been recently approved for the treatment of metastatic renal cell carcinoma and hepatocellular carcinoma. Up to 90 percent of patients receiving this drug have been reported to develop dermatological symptoms. Recently, it has been suggested that the appearance of skin toxicity during therapy may indicate antitumor activity. We report a new case of sorafenib-induced severe hand-foot skin reaction, which hindered the patient's normal life. The reaction was successfully treated with topical costicosteroids and discontinuation of sorafenib. However, the patient died one month later.

Abstract
OBJECTIVES To evaluate the feasibility and the processing time of offline analysis of three-dimensional (3D) brain volumes to perform a basic, as well as a detailed, targeted, fetal neurosonogram. METHODS 3D fetal brain volumes were obtained in 103 consecutive healthy fetuses that underwent routine anatomical survey at 20-23 postmenstrual weeks. Transabdominal gray-scale and power Doppler volumes of the fetal brain were acquired by one of three experienced sonographers (an average of seven volumes per fetus). Acquisition was first attempted in the sagittal and coronal planes. When the fetal position did not enable easy and rapid access to these planes, axial acquisition at the level of the biparietal diameter was performed. Offline analysis of each volume was performed by two of the authors in a blinded manner. A systematic technique of 'volume manipulation' was used to identify a list of 25 brain dimensions/structures comprising a complete basic evaluation, intracranial biometry and a detailed targeted fetal neurosonogram. The feasibility and reproducibility of obtaining diagnostic-quality images of the different structures was evaluated, and processing times were recorded, by the two examiners. RESULTS Diagnostic-quality visualization was feasible in all of the 25 structures, with an excellent visualization rate (85-100%) reported in 18 structures, a good visualization rate (69-97%) reported in five structures and a low visualization rate (38-54%) reported in two structures, by the two examiners. An average of 4.3 and 5.4 volumes were used to complete the examination by the two examiners, with a mean processing time of 7.2 and 8.8 minutes, respectively. The overall agreement rate for diagnostic visualization of the different brain structures between the two examiners was 89.9%, with a kappa coefficient of 0.5 (P < 0.001). CONCLUSIONS In experienced hands, offline analysis of 3D brain volumes is a reproducible modality that can identify all structures necessary to complete both a basic and a detailed second-trimester fetal neurosonogram.

Abstract
OBJECTIVES To explore the feasibility and added value of three-dimensional (3D) inversion rendering of the developing embryonic/fetal ventricular system, and to apply this display technique to enhance the sonographic examination of holoprosencephaly. METHODS 3D volumes of the embryonic/fetal brain were acquired from four normal fetuses at 8-11 postmenstrual weeks, and four fetuses diagnosed with holoprosencephaly between 9 and 14 postmenstrual weeks. The volumes were then analyzed offline to obtain inversion rendered 3D shapes of the ventricular systems. RESULTS All inversion rendering displays were successful and provided the opportunity to study normal as well as pathological aspects of the early fetal brain. CONCLUSIONS Inversion rendering of early fetal brain ventricles is feasible and should be attempted if additional information about the early normal or pathological fetal brain is needed. It may have scientific value in embryologic or genetic studies.

Abstract
OBJECTIVE Discussion of isolated ultrasound (US) markers for fetal aneuploidy can provoke significant patient anxiety. The objective of this study is to quantify maternal anxiety associated with the detection of these markers. METHODS All patients undergoing routine second-trimester US examination for fetal anatomical survey over a one-year period were administered the State-Trait Anxiety Inventory (STAI) for Adults before and after the procedure. Women with isolated fetal markers for aneuploidy were notified of the findings but discouraged from pursuing amniocentesis. Rates of normal US examination, aneuploidy markers, anomalies, amniocentesis, and pregnancy outcomes were assessed across the ethnic groups. Pre- and post-ultrasound STAI surveys were scored and standardized with previously established norms. Student t-tests, Chi-square, and analysis of variance (ANOVA) were used where appropriate. RESULTS Among the 798 patients tested, 57% were Hispanic, 30% were Asian, 6% were Black, and 7% were White. Maternal anxiety level was decreased in women after a normal US. The anxiety level increased with aneuploidy markers and was the highest with anomalies. Aneuploidy markers were more common among Hispanic and Asian fetuses, without any associated aneuploidy. Women with isolated aneuploidy markers underwent amniocentesis as often as women with advanced maternal age. CONCLUSION The detection and communication of isolated aneuploidy markers is associated with increased maternal anxiety and unnecessary amniocentesis.

Abstract
OBJECTIVES To describe a series of consecutive cases of live ectopic pregnancies managed with ultrasound-guided local injection of methotrexate (MTX) or potassium chloride (KCl). METHODS Eighteen consecutive women with live and unruptured, tubal, cornual or cervical ectopic pregnancies referred to our unit for evaluation and management underwent risk-benefit counseling. Under transvaginal ultrasound guidance, puncture and injection of the ectopic pregnancy was performed using an automated puncture device. Either MTX or KCl was injected, producing immediate cessation of fetal cardiac activity. RESULTS Of the 18 ectopic pregnancies, 10 were cervical, four were tubal and four were cornual. The mean initial beta-hCG level was 33 412 IU and the mean gestational age was 6 + 6 weeks. Ten ectopic gestational sacs were injected with KCl and eight were injected with MTX. There was no difference in time to resolution of the ectopic pregnancies between those injected with KCl and those with MTX. CONCLUSIONS Unruptured live ectopic pregnancies of many types can be successfully managed without surgical intervention through local injection of KCl or MTX.

Abstract
OBJECTIVE Fecal incontinence affects 0.2% of women aged 15-64 years and about 1.3% of women over 64 years. Most cases are related to instrumental deliveries affecting the anal sphincter complex. We propose a simple technique using the generally available transvaginal transducer to evaluate the anal sphincter complex. METHODS Ninety-two patients underwent ultrasound examination. Group I consisted of 53 nulliparous patients. In Group II there were six patients with normal spontaneous vaginal deliveries without episiotomies. In Group III there were 14 patients with vaginal deliveries and one to three episiotomies but no lacerations. In Group IV there were nine postpartum patients with recently repaired (48 h to 3 weeks) third- and fourth-degree lacerations. All women in Groups I-IV were asymptomatic. Group V consisted of 10 patients symptomatic for fecal incontinence. We used a vaginal probe (5-9-MHz) with the footprint placed in the fourchette pointing towards the anus in a transverse and then in a median (sagittal) plane. If seen, the combined internal and external anal sphincter thickness at the 12 o'clock location was measured. We visualized normal star-shaped mucosal folds on the transverse section and described the sonographic anatomy in both planes. RESULTS The mean sphincter thickness measured at 12 o'clock in Group I was 2.3 (range, 1.0-4.7) mm, in Group II it was 2.9 (range, 2.4-3.4) mm, and in Group III it was 2.3 (range, 1.0-3.7) mm. The differences between these three groups were not significant. Patients from Group IV showed thinning or discontinuous sphincter anatomy at the 12 o'clock position. All symptomatic patients from Group V showed abnormal sphincter anatomy, and the normal star-like appearance of the anal mucosa on the transverse section was deformed, radiating from the point of the sphincter damage. Four of the 10 patients in this group underwent surgical repair. In these patients the sonographic findings were confirmed. CONCLUSIONS The images obtained using this imaging modality show the sphincter muscle anatomy as well as the possible pathology. Due to its simplicity the technique can be applied in any place where a vaginal transducer is available.

Abstract
Previous work has shown that tree turnover, tree biomass and large liana densities have increased in mature tropical forest plots in the late twentieth century. These results point to a concerted shift in forest ecological processes that may already be having significant impacts on terrestrial carbon stocks, fluxes and biodiversity. However, the findings have proved controversial, partly because a rather limited number of permanent plots have been monitored for rather short periods. The aim of this paper is to characterize regional-scale patterns of 'tree turnover' (the rate with which trees die and recruit into a population) by using improved datasets now available for Amazonia that span the past 25 years. Specifically, we assess whether concerted changes in turnover are occurring, and if so whether they are general throughout the Amazon or restricted to one region or environmental zone. In addition, we ask whether they are driven by changes in recruitment, mortality or both. We find that: (i) trees 10 cm or more in diameter recruit and die twice as fast on the richer soils of southern and western Amazonia than on the poorer soils of eastern and central Amazonia; (ii) turnover rates have increased throughout Amazonia over the past two decades; (iii) mortality and recruitment rates have both increased significantly in every region and environmental zone, with the exception of mortality in eastern Amazonia; (iv) recruitment rates have consistently exceeded mortality rates; (v) absolute increases in recruitment and mortality rates are greatest in western Amazonian sites; and (vi) mortality appears to be lagging recruitment at regional scales. These spatial patterns and temporal trends are not caused by obvious artefacts in the data or the analyses. The trends cannot be directly driven by a mortality driver (such as increased drought or fragmentation-related death) because the biomass in these forests has simultaneously increased. Our findings therefore indicate that long-acting and widespread environmental changes are stimulating the growth and productivity of Amazon forests.

Abstract
A fetus was suspected of having a sacrococcygeal teratoma (SCT) on routine nuchal translucency evaluation by sonography at 12+3 weeks. The patient was referred for three-dimensional (3D) sonography to further delineate the extent of the mass. In this case, real-time scanning of the mass in 3D mode assisted the diagnosis of the mass and patient counseling. We present what we believe to be the first case of SCT imaged in the first trimester using 3D ultrasound.

Abstract
OBJECTIVE In scanning the female pelvis the clear images of transvaginal sonography (TVS) result from placing the transducer close to the region of interest. The advantages of TVS over transabdominal sonography (TAS) and transperineal sonography are well documented. Transrectal scanning is proposed mostly for ultrasound guidance in draining a pelvic abscess. Our aim was to investigate the applicability of transrectal scanning (TRS) for cases in which TVS is impossible. METHODS Forty-two patients with an absolute or a relative contraindication to TVS were scanned transabdominally and transrectally. The TRS was performed using a transvaginal probe, which was lubricated and slowly advanced into the rectum. The technique used was similar to that of TVS. Images were compared for resolution and quality. RESULTS All scans were completed without significant patient discomfort or complaints. TRS was clearly superior to TAS in 31 cases. In nine cases TAS furnished some clinical information but TRS yielded better images. Only in one such case was TAS similar in quality to TRS. In four obese patients TAS did not reveal sufficient pelvic anatomy to generate a clinical diagnosis, whereas TRS revealed two sets of normal ovaries and two patients with ovarian cysts. In the two cases with vaginal agenesis TRS revealed the diagnosis of Rokitansky-Küster syndrome. In three of the four patients with ruptured membranes the cervix could be measured precisely. CONCLUSION Transrectal scanning should be used liberally after proper patient selection and counseling. The images obtained are superior to TAS and comparable to those obtained by TVS.

Abstract
OBJECTIVE To apply an existing diagnostic imaging test (saline infusion sonohysterography) to characterize the "filling defect" of a previous cervical cesarean delivery scar in the nonpregnant uterus. METHODS Forty-four patients with histories of cesarean delivery who underwent saline infusion sonohysterography for a variety of gynecologic indications were included. During the procedure, the area below the bladder recess was examined using transvaginal sonography. A filling defect or "niche" was defined as a triangular anechoic structure at the presumed site of a previous cesarean delivery scar. The depth of the niche was measured. Uterine size, the presence of fibroids and polyps, and the number of previous cesarean deliveries were noted. RESULTS All patients had a niche indenting the anterior uterine-cervical wall. The mean +/- SD depth of the niche was 6.17 +/- 3.6 mm. There was no correlation between the number of cesarean deliveries and the depth of the niche. Thirty-six percent of our patients had fibroids, and 18% had endometrial polyps. CONCLUSION Saline infusion sonohysterography was able to detect filling defects in women who previously had cesarean deliveries. We hope that by focusing our attention on the transvaginal sonographic appearance of the detectable uterine scar (niche) with or without the use of saline infusion sonohysterography in the nonpregnant uterus, it will train our eyes to look for the scar in the pregnant uterus. In addition, our study patients had a high prevalence of abnormal uterine bleeding. The role of the cesarean delivery scar in women with unscheduled bleeding needs to be further evaluated.

Abstract
OBJECTIVES Fetal neuroscan by ultrasound has gained in importance over recent years. Two-dimensional (2D) transvaginal sonography was an important step in understanding the constantly changing and developing fetal brain. The objective of this article is to describe the use of three-dimensional ultrasound of the fetal brain enhanced by the transvaginal transfontanelle scanning technique. METHODS Thirty-four pregnant patients were referred to us because of a history of brain anomaly or suspected brain pathology. The fetuses were scanned transvaginally. Two-dimensional as well as three-dimensional (3D) images were generated. The volumes obtained by the 3D-ultrasound machine were displayed in the three conventional orthogonal planes (coronal, sagittal and axial). RESULTS Of the 34 fetuses 10 had normal brain anatomy and 24 had brain pathology. In all 34 cases the 2D images as well as the 3D volumes were of diagnostic quality and all three planes could be obtained. The axial sections could only be obtained by the 3D re-construction of the volume scans. The 2D images produced were acquired from a common point originating from the foot print of the transvaginal probe at the fetal anterior fontanelle or the sagittal suture, the sections 'radiate' from this point. Therefore, these sections are not parallel sections, but are oblique to each other. In contrast, the 3D volume could be examined using the classical parallel sections in all three orthogonal planes. The posterior fossa could be seen better if the footprint of the probe was placed over the posterior fontanelle or on the sagittal suture. The marker dot enabled a precise creation of anatomy and pathology. In the 'angio mode' it was possible to follow the anterior cerebral and pericallosal artery. CONCLUSIONS The 3D-ultrasound technology using the transvaginal approach is effective and practical to perform during fetal neuroscan. The ability to 'navigate' in the volume and the 'marker dot' enables exact location of normal structures and evaluation fetal brain pathology. The volume can be reviewed over and over again, can be mailed to an expert, could be shown to consultants (pediatric neurology and neurosurgeons) and used for teaching.

Abstract
OBJECTIVE To describe an easy technique for obtaining one of the most important views of the fetal brain and image. The entire lateral ventricle including the anterior, posterior and inferior horns is demonstrated on one image. We propose to call this view, obtained in an oblique plane 'the three horn view'. METHODS Depending upon the scanning technique employed there are two ways to obtain the three horn view: (1) by two-dimensional (2D) transvaginal transfontanelle sonography obtained by using the left and right Oblique-1 sections, and (2) by three-dimensional (3D) imaging of the fetal brain, is obtained by acquiring a volume scan of the brain orienting the fetal head in the three main orthogonal planes and by rotating or tilting the midcoronal section to the left and right. RESULTS To illustrate the technique of obtaining the three horn view four normal fetal brains were scanned. Two scans utilized the 2D transvaginal transfontanelle approach and two scans utilized the 3D scanning technique. The same technique was then applied to six fetuses with various brain malformations with inflicted changes in the shape of the proposed three horn view. CONCLUSION The three horn view, depicting the anterior, posterior, and inferior horns on the same image, was easy to obtain using both the 2D and the 3D ultrasound techniques. It provided diagnostic and clinically useful information much like neonatal transfontanelle ultrasound imaging after which it was emulated.

Abstract
OBJECTIVE To develop a simple and systematic algorithm to determine chorionicity and amnionicity in the second and third trimester by ultrasound. STUDY DESIGN The algorithm was constructed based upon years of experience in examining multifetal pregnancies and by adopting the different sonographic signs suggested in the literature. RESULTS The following parameters were used to construct the algorithm: sexing of the fetuses, placental location, and origin, thickness and number of layers of the membranes. CONCLUSION The flow chart developed is simple to use and embodies all possible sonographic parameters to help determine chorionicity and amnionicity in the second and third trimester.

Abstract
OBJECTIVE This report reviews the obstetric outcomes of women with multifetal pregnancy reductions who subsequently underwent elective amniocentesis. STUDY DESIGN Five hundred eight patients underwent multifetal pregnancy reduction at our institution. Among these, 91 patients underwent subsequent elective amniocentesis. The obstetric outcomes of all 508 patients were followed up. By means of logistic regression we evaluated several variables to determine any association with loss rate: (1) the finishing number of fetuses, (2) the number of fetuses undergoing reduction (starting number of fetuses minus the finishing number of fetuses), (3) the gestational age at reduction, (4) the maternal age at reduction, and (5) the procedure protocol. We observed that the finishing number of fetuses, the number of fetuses removed, and the procedure protocol were significantly associated with pregnancy loss rate. Women who underwent subsequent amniocentesis were compared with those who did not undergo amniocentesis. By means of multivariate conditional likelihood analysis we stratified the two groups according to the previously mentioned significant variables to compare the pregnancy loss rates. RESULTS Among patients who subsequently underwent elective amniocentesis the total uncorrected pregnancy loss rate was 9.0% and the early premature delivery rate was 4.5%. The number of fetuses removed, the finishing number of fetuses, and the procedure protocol were statistically significantly associated with the loss rate. The adjusted odds ratio relating amniocentesis to the pregnancy loss rate was 0.7 (95% confidence interval, 0.31.5; P =.3.) CONCLUSIONS The uncorrected rates of pregnancy loss and of early premature delivery among patients with multifetal pregnancy reduction who underwent subsequent amniocentesis were comparable to those of patients with multifetal pregnancy reduction who did not undergo amniocentesis.

Abstract
OBJECTIVE To determine if analyzing the entire color Doppler image (CDI) pulse wave of an ovarian mass can improve the ability to predict its histopathology. STUDY DESIGN The CDI of 42 histopathologically diagnosed adnexal masses were retrospectively analyzed. Using an image analysis software program, the following parameters were calculated: area under the curve, compactness, Feret diameter, perimeter, shape factor and width of the waveform. Using an automated curve-fitting software program, the up and down slopes were processed separately for the optimal equation and coefficient for each slope. Two computerized neural networks were created, both consisting of an input layer, one hidden layer and an output layer of three neurons: benign, borderline and malignant. The first network contained two input neurons: pulsatility index (PI) and resistance index (RI). The second network contained 10 input neurons consistent with the shape and slope parameters calculated. The coefficient of determination (R2) was determined for each network. RESULTS The neural network utilizing RI and PI failed to train (1,397 runs, 67,056 facts, R2 = 0.59, 0.12 and 0.43 for benign, borderline and malignant masses, respectively). The network using the 10 calculated parameters achieved an R2 of 0.96 after 685 runs and 27 facts. CONCLUSION Analyzing the CDI studies of ovarian masses, using the entire pulse wave, improved the ability to differentiate between their benign, borderline and malignant histopathology.

Abstract
OBJECTIVES Since the introduction of transvaginal sonography (TVS), clear pictures of the female reproductive tract have been obtained. These images enable the accurate description of Fallopian tube pathology. However, the current literature on the ultrasound diagnosis of pelvic inflammatory disease (PID) is confusing and contradictory. The goal of our study was to identify sonographic markers of inflammatory disease of the pelvis and to place these in a clinical context. PATIENTS AND METHODS Seventy-seven patients were scanned by TVS. They were divided into two groups, according to their clinical picture, the first group with acute PID and the second with a history of chronic PID or no history at all. The sonographic markers studied were shape, wall structure and wall thickness of the Fallopian tube. Ovarian involvement and the presence of pelvic fluid were also evaluated. RESULTS The best marker of tubal inflammatory disease, either acute or chronic, was the presence of an incomplete septum of the tubal wall, which was present in 92% of the total cases. A thick wall and the 'cogwheel' sign were sensitive markers of acute disease, whereas a thin wall and 'beads-on-a-string' sign were indicators of chronic disease. Palpable findings and surgical history were not discriminatory, but were present in three-quarters and one-third of the study population, respectively. Three false-positive cases are presented: an ovarian cystadenoma, an appendiceal mucocele and one case with periovarian fluid accumulation. CONCLUSIONS The tubo-ovarian complex and the tubo-ovarian abscess should be considered separate entities that differ in their clinical implications. TVS allows one to distinguish between them. Distinguishing characteristics of acute and chronic salpingitis are presented.

Abstract
During the first trimester, chorionicity can be assessed as early as five weeks post-conception, but a reliable detection of amnionicity cannot be performed before the 8th week when the amnion can be clearly imaged. The late second and third trimesters twin pregnancies are a true challenge to the imaging specialist because the detection of chorionicity and amnionicity has to rely upon sonographic clues, such as placenta location, fetal gender, membrane origin, thickness, and layer. Sonographic methods used to determine chorionicity and amnionicity in twins can be extrapolated to any multifetal pregnancy, regardless of the number of fetuses present.

Abstract
We have previously reported on the value of transvaginal color Doppler evaluation of the ureteral jets to confirm ureteral patency. In this study, we attempt to validate the simple and widely available gray-scale ultrasound technique to perform the same task. Fifty consecutive patients without a history of urinary complaints were recruited. The presence or absence of the right and left ureteral jets was registered using gray-scale imaging, comparing the technique to color Doppler as the 'gold standard'. The time to the detection of the first jet as well as the total scanning time were documented for each side. The jets were seen with equal frequency on both the right and the left sides (34 observations each). In 24 patients, both jets were visualized. The median time to detection of the first jet was 47 s (range 34-79 s) for the right jet and 53 s (36-84 s) for the left jet (p = 0.42). The median total scanning time was 176 s (139-259 s). Gray-scale imaging was associated with a sensitivity of 68% and a positive predictive value of 100%. Although color Doppler results may be more attractive because of their impressive color-coded appearance, the major disadvantage of this technique is that it requires sophisticated and costly equipment. Transvaginal gray-scale imaging is a reliable and useful test for the detection of ureteral jets in the bladder. It can be used as a first-line diagnostic tool, particularly in settings where color Doppler is not available. Its benefits include safety, low cost, convenience and simplicity. With a positive predictive value of 100%, this test may be used in the postoperative patient, especially when ureteral patency is in question.

Abstract
OBJECTIVE We raise the issue of scanning multifetal pregnancies of higher order as early as possible. A rare case of monochorionic/quadramniotic pregnancy seeking multifetal pregnancy reduction and its clinical management is presented. METHODS Transabdominal scanning at 16 weeks was performed correctly diagnosing the monochorionic quadruplet pregnancy. RESULTS Suspecting vascular connections between the placentae, the fetal reduction was declined. The patient was delivered at 31 weeks. The 4 female neonates survived with slight ventilatory assistance. CONCLUSION Multifetal pregnancies in general, but those of higher order in particular, have to be scanned as early as 8-10 weeks to correctly and easily assign their chorionicity and amnionicity. The case of a monochorionic/quadramniotic pregnancy and its clinical course are presented.

Abstract
The goal of the gynecologist is to detect ovarian tumors in their earliest stages. Small virilizing tumors, which barely affect the size of the ovaries, are such lesions. Since the introduction of transvaginal sonography it is technically possible to detect small intraovarian neoplasms. Three cases of virilizing steroid cell tumors in postmenopausal women with ovarian volumes just exceeding the normal sizes for age are presented. High-frequency transvaginal ultrasound and color Doppler studies to measure flow parameters were used. These small tumors had different echogenicity from the surrounding ovarian tissue and two had low impedance-to-flow values. Gray-scale transvaginal sonography combined with color Doppler studies can make the diagnosis of small steroid cell tumors easier and, at times, better than other, more costly imaging modalities.

Abstract
We aimed to determine the feasibility of imaging specific sulci, gyri and fissures using transvaginal sonography and to correlate their first sonographic recognition with gestational age. Retrospectively, 262 fetal brain scans were analyzed from a total of 337 scans. Scans were selected if any of the following structures were seen: in the coronal plane the lateral, callosal and cingulate sulcus and gyrus; in the median plane the parieto-occipital and calcarine fissures, and the cingulate gyrus and sulcus; and, in an oblique section, the lateral sulcus. The gestational age at which the fissures, sulci and gyri were first imaged was recorded and subsequently compared with similar anatomical studies from the literature. It was possible to identify all the targeted structures. The gestational ages at which the structures were first imaged were: the callosal sulcus, from 14 weeks; the lateral sulcus, from 18 weeks; the parieto-occipital sulcus and calcarine fissure, from 18 weeks; and the cingulate gyrus, from 26 weeks. We concluded that the developmental maturation of the normal fetal brain follows a predictable timetable, and that this maturation can be grossly followed with sonography. The sonographic recognition of the fissures, gyri and sulci lagged behind the observations by anatomical studies. The greatest discrepancy was the first appearance of the cingulate gyrus which, in the anatomical studies, could be seen by 18 postmenstrual weeks and, in our study, was seen after 26 postmenstrual weeks. The one exception was the callosal sulcus, which was first seen at 14 postmenstrual weeks in both the sonographic and anatomical studies. In conclusion, the recognition of specific structures of the cortical map is possible. Sonography may be used to image the developing cortical surface.

Abstract
OBJECTIVE To evaluate the feasibility of the detection of ureteral jets into the bladder in obstetric-gynecologic patients using transvaginal color Doppler ultrasound. METHODS Fifty-two women were recruited and categorized into four groups: 1) 20 normal nonsurgical, 2) 17 post-cesarean delivery, 3) 12 post-total abdominal hysterectomy, and 4) three with only one functional kidney or ureter. In the first three groups, transvaginal color Doppler sonography was used to evaluate the time to detection of the first jet and the number of jets in 5 minutes bilaterally. In the last group, the presence or absence of the jet was documented only on the functional side. Statistical analysis was performed using Student t test and analysis of variance followed by Tukey honestly significant difference. RESULTS Urine jets could be detected bilaterally in all women except for those with only one functional kidney (accuracy 100%). Time to detection of the first jet did not differ significantly in the nonsurgical, cesarean, or hysterectomy patients on either the right side (P = .07) or the left side (P = .43). The total number of jets was similar in the nonsurgical and cesarean patients, but was significantly lower in the hysterectomy group (right side P = .006; left side P = .004). In the women with one functional kidney, the normal side was identified in all cases. CONCLUSION Transvaginal color Doppler sonography is a simple, accurate technique that can be used to evaluate ureteral jets into the bladder in women. The length of time to detection of the first jet is not affected by the postoperative status. Fewer jets should be expected in women who have undergone hysterectomies. This method should be used when ureteral integrity is in question, especially after surgery.
