RESUMO

PURPOSE: The objective of this study is to assess the correlation between bleeding irregularities and the accurate placement of the intrauterine device (IUD) device in the uterine cavity, determined through transvaginal ultrasonography and hysteroscopy. In addition, the study aims to examine the cytokine profile in the uterine cavity and serum of patients experiencing bleeding irregularities after the insertion of nonhormonal IUDs. METHODS: A prospective cohort study was conducted at a single tertiary medical center, wherein patients experiencing intermenstrual bleeding and spotting after the insertion of nonhormonal IUDs were enrolled. The study involved hysteroscopic and sonographic assessments of the uterine cavity and IUD placement, along with the analysis of blood and uterine cavity cytokine profiles. RESULTS: During the period between July 2019 and February 2020, a total of eight patients who experienced intermenstrual bleeding and spotting after the insertion of nonhormonal IUDs were enrolled the study. One case was excluded since a progestative device was detected by ultrasound. Out of the five cases that underwent a thorough ultrasonographic assessment, three cases (60%) showed an embedded IUD. However, these findings were excluded by the hysteroscopic evaluation. CONCLUSION: The results suggest that ultrasonographic assessment may lead to an overdiagnosis of IUD mispositioning compared to hysteroscopy. In addition, both ultrasound and hysteroscopy have limitations in diagnosing the cause of bleeding in most cases. The role of local reactive inflammatory cytokines should be further studied.

RESUMO

OBJECTIVE: The aim of this study was to describe the anatomy of the portal system in fetuses with persistent right umbilical vein (PRUV). METHODS: Prospective observational study of fetuses diagnosed with PRUV. All patients underwent a comprehensive portal system anatomy scan supplemented by two-dimensional (2D) and three-dimensional (3D) color doppler modalities. RESULTS: 29 fetuses with PRUV were studied. We perceived an identical anatomical pattern in 28 fetuses. The right umbilical vein drains to the portal sinus (future right portal vein, RPV), which has a configuration of a left portal vein (LPV) in the normal left portal system, with three emerging branches: inferior (RPVi), medial (RPVm) and superior (RPVs). The RPV then courses to the left, towards the stomach to the point of the bifurcation of the main portal vein (MPV) to become the left portal vein. The LPV has an RPV configuration in a normal portal system with anterior (LPVa) and posterior (RPVp) branches. This anatomical layout mimics a mirror image of the normal anatomy of left portal system. CONCLUSION: PRUV has unique umbilical portal venous anatomy, which is a mirror image of the normal left portal system. It can be demonstrated prenatally and serve as an additional tool for prenatal diagnosis of PRUV.

RESUMO

BACKGROUND: Advances in examination techniques have improved routine assessment of non-gynecological structures in the pelvis. OBJECTIVES: To describe the sonographic features of incidental urological abnormalities found during gynecological transvaginal ultrasound. METHODS: A retrospective descriptive analysis of patients who underwent gynecological ultrasound and were diagnosed with urologic findings was performed. The sonographic features of the findings including size, echogenicity, and vascularity were examined. RESULTS: Gynecological ultrasound diagnosed urological findings in nine women. Two had primary neoplasms of the urinary bladder, one had metastases to the urinary bladder, one had polyps in the distal ureters, four presented with calculus in the distal ureters (one of them was 19 weeks pregnant), and one showed diverticulum of the urethra. At presentation five women (56%) had urinary complaints. Two patients (22%) with abdominal pain with distal ureteral calculi had normal transabdominal ultrasound targeted to the urinary system prior to the gynecological sonography. CONCLUSIONS: Transvaginal ultrasound is useful in the diagnosis of urological abnormalities, mainly in the urinary bladder and the distal ureters. We suggest adding transvaginal assessment for female patients with urinary complains in whom transabdominal ultrasound of urinary system was unremarkable.

RESUMO

OBJECTIVES: Abnormal fetal tongue size is a phenotypic feature of various syndromes including Beckwith-Wiedemann, Pierre-Robin, oromandibular limb hypoplasia, chromosomal aberrations, etc. Current data regarding normal fetal tongue size are limited. Hence, micro/macroglossia are subjectively determined. The aim of the study was to construct a contemporary fetal tongue nomogram and to assess its clinical contribution. METHODS: A prospective cross-sectional study was performed in well dated, low risk, singleton pregnancies. Fetal tongues were measured by 5 trained sonographers. Highest quality images were selected. Intra- and interobserver variability was assessed. Tongue length, width, area, and circumference 1st to 99th centiles were calculated for each gestational week. Based on the normal tongue size charts, we created a Tongue Centile Calculator. RESULTS: Over 18 months, 664 tongue measurements were performed. A cubic polynomial regression model best described the correlation between tongue size and gestational age. The correlation coefficient (r2 ) was 0.934, 0.932, 0.925, and 0.953 for tongue length, width, area, and circumference, respectively (P < .001). Intra- and interobserver variability had high interclass correlation coefficients (>0.9). Using the new charts, we were able to identify 2 cases of macroglossia, subsequently diagnosed with Beckwith-Wiedemann, and 4 cases of microglossia, 3 associated with Pierre-Robin sequence, and 1 associated with persistent buccopharyngeal membrane. CONCLUSIONS: We present novel fetal tongue size charts from 13 to 40 weeks of gestation. Clinical application of these nomograms may be beneficial in the prenatal diagnosis of syndromes or malformations associated with abnormal fetal tongue size.

RESUMO

PURPOSE: To evaluate the relationship between gastrointestinal (GI) symptoms and transvaginal ultrasound (TVUS) findings suggestive of endometriosis. MATERIALS AND METHODS: A prospective design. Women referred for a diagnostic ultrasound due to suspicion of endometriosis completed a Rome III and Pelvic Floor Distress Inventory (PFDI-20) questionnaire for clinical, GI symptoms, before undergoing TVUS. Endometriosis was diagnosed in the presence of endometriomas and/or deeply infiltrative endometriotic (DIE) lesions. Association between lesion sites and GI symptoms was evaluated by univariate and multivariate analysis. RESULTS: The study included 241 women who presented with: dysmenorrhea (89.6 %), dyspareunia (76.3 %), chronic pelvic pain (77.2 %), dyschezia (66 %), hematochezia (15.4 %), subfertility (24.5 %). GI symptoms were present in 25.3-76.8 % and 5.4-55.6 % of Rome III and PFDI-20 questionnaire responses, respectively. TVUS findings were endometriomas (23.2 %), peritoneal adhesions (46.5 %), uterosacral ligament (26.7 %), retrocervical (11.2 %), rectosigmoid (11.2 %), intestinal (4.6 %), and bladder (0.8 %) involvement, and pouch of Douglas (POD) obliteration (15.4 %). There was a high prevalence of peritoneal adhesions, uterosacral ligament involvement, and rectosigmoid and intestinal nodules on TVUS in women with GI symptoms, up to Chi2 = 9.639 (p = 0.013) on univariate and Chi2 = 8.102 (p = 0.005) on multivariate analysis. CONCLUSION: We observed an almost 10-fold increase in DIE lesions in women with GI symptoms. We suggest that the presence of GI symptoms should prompt a referral for endometriosis evaluation and performance of a dedicated TVUS before invasive gastrointestinal procedures.

RESUMO

BACKGROUND: Esophageal atresia is a major anomaly with a low prenatal detection rate. We propose a sonographic method termed dynamic esophageal patency assessment. OBJECTIVE: This study aimed to assess the feasibility and performance of the dynamic esophageal patency assessment in a high-risk population. STUDY DESIGN: A prospective study was conducted in a single tertiary fetal ultrasound unit for 12 months. The study group included pregnant women referred for a targeted scan because of one or more of the following: (1) polyhydramnios; (2) small or absent stomach; (3) vertebral, anal atresia, cardiac, tracheoesophageal fistula, renal, and limb abnormalities; (4) first-degree relative with esophageal atresia; and (5) genetic mutation associated with esophageal atresia. In addition to dynamic esophageal patency assessment, a comprehensive anomaly scan was carried out. The fetal esophagus was observed during swallowing. Cases that demonstrated uninterrupted fluid propagation through the esophagus were classified as normal. Cases that demonstrated interrupted fluid propagation, with the formation of a pouch, were classified as abnormal. Cases with unclear visualization of the esophagus or cases that failed to demonstrate either fluid propagation or a pouch were classified as undetermined. Dynamic esophageal patency assessment results were compared with postnatal findings, considered "gold standard." Test performance indices and intra- and interobserver agreements were calculated. RESULTS: For 12 months, 130 patients were recruited, and 132 fetuses were scanned. The median gestational age (interquartile range) at the time of scan was 31.4 weeks (29.0-35.3). Of 132 fetuses enrolled, 123 (93.2%) were normal, 8 (6%) were abnormal, and 1 (0.8%) was undetermined. Excluded from test performance analysis were 3 cases that were terminated without postmortem autopsy (1 was abnormal and 2 were normal), and a fourth case was excluded as it was classified as undetermined. The detection rate of esophageal atresia was 100%, with no false-positive or false-negative case. Sensitivity, specificity, and positive and negative predictive values of the dynamic esophageal patency assessment were 100%. The Kappa coefficient was 1 for both inter- and intraobserver agreements (P<.0001). The median time (interquartile range) required to complete the dynamic esophageal patency assessment was 6.00 minutes (3.00-13.25). CONCLUSION: The dynamic esophageal patency assessment is a feasible and highly effective method of ascertaining an intact esophagus and detecting esophageal atresia in suspected cases.

RESUMO

OBJECTIVE: The purpose of this series was to describe the prenatal diagnosis and pregnancy outcome of fetuses affected by a transient idiopathic fetal sternal cyst. METHODS: Two fetuses had the diagnosis of an isolated presternal cyst at routine sonography at 15 weeks. A follow-up sonographic examination was done, and the neonates were examined after birth. RESULTS: In both cases, the cyst disappeared at 20 weeks' gestation, and both fetuses had only a small dimple at the location of the cyst. CONCLUSIONS: An isolated presternal cyst is an extremely rare finding. It should be followed sonographically, and if it disappears within a few weeks, the diagnosis of a dermal inclusion cyst should be suspected. Parents can be informed to anticipate a small depression on the neonate's chest.
