RESUMO

PURPOSE: To investigate the association of sonographic features and clinical symptoms of adenomyosis. METHODS: This was a prospective observational study. Only reproductive age women who underwent standardized transvaginal ultrasound examination were included. The diagnosis of adenomyosis was based on sonographic features proposed by Morphological Uterus Sonographic Assessment (MUSA) group. Pictorial blood loss assessment chart (PBAC) and numerical rating scale (NRS) were respectively used for the evaluation of menstrual bleeding and pain. RESULTS: Fifty-three women were recruited. Adenomyosis group consisted of 33 (62.3%) representative cases, whereas control group consisted of 20 (37.7%). Women with adenomyosis experienced significantly heavier menstrual bleeding (p = 0.008) and more painful menstrual periods (p = 0.003). Significant positive correlation between the number of sonographic adenomyosis features and both PBAC (r = 0.613, p < 0.001) and NRS scores (r = 0.402, p = 0.022) was found. PBAC score was significantly higher if either fan-shaped shadowing (r = 0.548, p = 0.001), interrupted junctional zone (JZ) (r = 0.548, p = 0.001) or globular uterus (r = 0.445, p = 0.011) was detected. Interrupted JZ (r = 0.440, p = 0.012) was associated with higher NRS score. Significant positive correlation between PBAC score and adenomyosis spread in uterine layers (r = 0.495, p = 0.004) was established. CONCLUSION: Certain sonographic features of adenomyosis and assessment of its involvement in uterine layers may predict the severity of adenomyosis symptoms.

RESUMO

In this study, we conducted a comparative analysis of demographic, histopathological, and sonographic characteristics between pre- and postmenopausal women diagnosed with endometrial cancer, while also examining sonographic and anthropometric features in 'low' and 'intermediate/high-risk' cases, stratified by menopausal status. Our analysis, based on data from the International Endometrial Tumor Analysis (IETA) 4 cohort comprising 1538 women (161 premenopausal, 1377 postmenopausal) with biopsy-confirmed endometrial cancer, revealed that premenopausal women, compared to their postmenopausal counterparts, exhibited lower parity (median 1, IQR 0-2 vs. 1, IQR 1-2, p = 0.001), a higher family history of colon cancer (16% vs. 7%, p = 0.001), and smaller waist circumferences (median 92 cm, IQR 82-108 cm vs. 98 cm, IQR 87-112 cm, p = 0.002). Premenopausal women more often had a regular endometrial-myometrial border (39% vs. 23%, p < 0.001), a visible endometrial midline (23% vs. 11%, p < 0.001), and undefined tumor (73% vs. 84%, p = 0.001). Notably, despite experiencing a longer duration of abnormal uterine bleeding (median 5 months, IQR 3-12 vs. 3 months, 2-6, p < 0.001), premenopausal women more often had 'low' risk disease (78% vs. 46%, p < 0.001). Among sonographic and anthropometric features, only an irregular endometrial-myometrial border was associated with 'intermediate/high' risk in premenopausal women. Conversely, in postmenopausal women, multiple features correlated with 'intermediate/high' risk disease. Our findings emphasize the importance of considering menopausal status when evaluating sonographic features in women with endometrial cancer.

RESUMO

Background and objectives: An expert's subjective assessment is still the most reliable evaluation of adnexal pathology, thus raising the need for methods less dependent on the examiner's experience. The aim of this study was to evaluate the performance of standardized methods when applied by examiners with different levels of experience and to suggest the most suitable method for less-experienced gynecologists. Materials and methods: This single-center retrospective study included 50 cases of histologically proven first-time benign or malignant adnexal pathology. Three examiners evaluated the same transvaginal ultrasound images: an expert (level III), a 4th year resident in gynecology (level I), and a final year medical student after basic training (labeled as level 0). The assessment methods included subjective evaluation, Simple Rules (SR) with and without algorithm, ADNEX and Gynecologic Imaging Reporting and Data System (GI-RADS) models. Sensitivity, specificity, accuracy, positive and negative predictive values with 95% confidence interval were calculated. Results: Out of 50 cases, 33 (66%) were benign and 17 (34%) were malignant adnexal masses. Using only SR, level III could classify 48 (96%), level I-41 (82%) and level 0-40 (80%) adnexal lesions. Using SR and algorithm, the performance improved the most for all levels and yielded sensitivity and specificity of 100% for level III, 100% and 97% for level I, 94.4% and 100% for level 0, respectively. Compared to subjective assessment, ADNEX lowered the accuracy of level III evaluation from 97.9% to 88% and GI-RADS had no impact. ADNEX and GI-RADS improved the sensitivity up to 100% for the less experienced; however, the specificity and accuracy were notably decreased. Conclusions: SR and SR+ algorithm have the most potential to improve not only sensitivity, but also specificity and accuracy, irrespective of the experience level. ADNEX and GI-RADS can yield sensitivity of 100%; however, the accuracy is decreased.

RESUMO

PURPOSE: To evaluate the agreement of wet smear microscopy with Gram stain microscopy and to assess whether it is possible to predict Mycoplasmas/Ureaplasmas when analysing vaginal secretion with Gram stain and wet smear microscopy. METHODS: Women with complaints of the abnormal vaginal discharge were invited to participate. A sample of vaginal secretion was taken for wet smear microscopy and for Gram staining analysis. A sample from the endocervical canal was taken for DNA detection of seven infections: Mycoplasma hominis, Mycoplasma genitalium, Ureaplasma parvum, Ureaplasma urealyticum, Chlamydia trachomatis, Neisseria gonorrhoeae and Trichomonas vaginalis. The percentage agreement between wet smear and Gram stain was determined and the Cohen's Kappa values were calculated. RESULTS: Of 158 consecutive women included, one (or a few) of the infections were detected in 54% of them and the most frequent infection was Ureaplasma parvum (79% of all the cases with infections). The percentage agreement between vaginal wet smear and Gram stain was 73% (Cohen's Kappa value 0.63). A statistically significant association between the DNA detected Mycoplasmas/Ureaplasmas and bacterial vaginosis was found (positive amine test p = 0.046, wet smear p = 0.005 and Gram stain p = 0.03). CONCLUSIONS: There was a statistically significant association between bacterial vaginosis and the DNA detected Mycoplasmas/Ureaplasmas. The agreement of vaginal wet smear with Gram stain was good.

RESUMO

The aim of this study was to assess if ureaplasmas are associated with pregnancy complications and diseases in newborns. Pregnant women with complaints and threatening signs of preterm delivery were included. A sample, taken from the endocervical canal and from the surface of the cervical portion, was sent to the local microbiology laboratory for DNA detection of seven pathogens: Chlamydia trachomatis, Mycoplasma hominis, Mycoplasma genitalium, Ureaplasma parvum, Ureaplasma urealyticum, Neisseria gonorrhoeae, and Trichomonas vaginalis. The Pearson Chi-Square test was used to determine the difference in unpaired categorical data. A two-sided p value <0.05 was considered to be statistically significant. In all, 50 pregnant women with complaints and threatening signs of preterm delivery were included. Premature rupture of uterine membranes was found in 23 (46%) of the patients and 38 women (76%) had preterm delivery. Ureaplasma infections were associated with a premature rupture of membranes (p < 0.004), the placental inflammation (p < 0.025), a newborn respiratory distress syndrome (p < 0.019). Ureaplasmas could have affected the preterm leakage of fetal amniotic fluid and are associated with the placental inflammation and a newborn respiratory distress syndrome.

RESUMO

OBJECTIVES: To describe sonographic features of the microcystic elongated and fragmented (MELF) pattern of myometrial invasion (MI) using the International Endometrial Tumor Analysis (IETA) criteria; to assess the effect of the MELF pattern on preoperative ultrasound evaluation of MI; and to determine the relationship of the MELF pattern to more advanced stage (≥ IB) and lymph node metastases in women with endometrioid endometrial cancer. METHODS/MATERIALS: We included 850 women with endometrioid endometrial cancer from the prospective IETA 4 study. Ultrasound experts performed all ultrasound examinations, according to the IETA protocol. Reference pathologists assessed the presence or absence of the MELF pattern. Sonographic features and accuracy of ultrasound assessment of MI were compared in cases with the presence and the absence of the MELF pattern. The MELF pattern was correlated to more advanced stage (≥IB) and lymph node metastases. RESULTS: The MELF pattern was present in 197 (23.2%) women. On preoperative ultrasound imaging the endometrium was thicker (p = 0.031), more richly vascularized (p = 0.003) with the multiple multifocal vessel pattern (p < 0.001) and the assessment of adenomyosis was more often uncertain (p < 0.001). The presence or the absence of the MELF pattern did not affect the accuracy of the assessment of MI. The MELF pattern was associated with deep myometrial invasion (≥ 50%) (p < 0.001), cervical stromal invasion (p = 0.037), more advanced stage (≥ IB) (p < 0.001) and lymph node metastases (p = 0.011). CONCLUSIONS: Tumors with the MELF pattern were slightly larger, more richly vascularized with multiple multifocal vessels and assessment of adenomyosis was more uncertain on ultrasound imaging. The MELF pattern did not increase the risk of underestimating MI in preoperative ultrasound staging. Tumors with the MELF pattern were more than twice as likely to have more advanced stage (≥ IB) and lymph node metastases.

RESUMO

OBJECTIVE: Current clinical practice of assessing neonatal condition is based on evaluation of umbilical cord arterial blood pH value rather than lactate. However, evidence shows that lactate is direct and more predictive measurement than pH or at least of equal importance. This study is to assess and compare umbilical cord arterial lactate and pH values for predicting short-term neonatal outcomes. MATERIALS AND METHODS: A retrospective cohort study was conducted at the tertiary level hospital, were arterial umbilical cord blood sampling was collected according to the standard procedures. Neonatal morbidity was registered if at least one of the following conditions was noted: Apgar score at 1 min after delivery was 6 or lower, resuscitation performed, including assisted ventilation and requirement of admission to neonatal intensive care unit. Mothers-newborns pairs were allocated into two groups: newborns exposed to perinatal hypoxia (group 1) and observed as healthy newborns (group 2). Receiver operating characteristics curves (ROC) were generated to assess the predictive ability of pH and lactate for the short-term neonatal outcomes. RESULTS: 901 neonates born at ≥37 weeks of gestation were included. Newborns exposed to perinatal hypoxia (group 1) encompassed 39 (4.3%) patients, and observed as healthy (group 2) - 862 (95.7%). Arterial umbilical cord blood pH in group 1 was 7.160 ± 0.126 as compared to 7.314 ± 0.083 in group 2; p < 0.001. Mean arterial lactate was significantly higher in group 1 than group 2 (6.423 ± 2.335 as compared to 3.600 ± 1.833; p < 0.001). The difference between areas under ROC curves representing pH and lactate was not significant (0.848 and 0.831 respectively; p = 0.6132). CONCLUSION: Umbilical cord arterial lactate and pH predicted short-term neonatal outcomes with similar efficacies.

RESUMO

PURPOSE: To evaluate whether the pain experienced during and after Saline-contrast sonohysterography (SCSH) differs between premenopausal and postmenopausal women. METHODS: Sonohysterography was performed on 133 consecutive women because of suspected endometrial pathology. Of these, 34 women were excluded for the following reasons: they had cervical stenosis; they did not complete or return a questionnaire; or tenaculum or cervical dilatators were used during the procedure. All women were asked to fill out a questionnaire to characterize their pain and mark their pain experience on a 100-mm pain visual analog scale. RESULTS: Data from the 99 patients included were used for statistical analysis. It showed that sonohysterography was well tolerated overall: 41% of the women did not feel any pain. Postmenopausal women experienced pain during SCSH more often than premenopausal women did: 71% (17/24) compared with 32% (24/75) experienced pain; p < 0.002; the median tolerance on the 100-mm visual analog scale was 43. The character of the pain differed between the two groups of women: postmenopausal women more often felt sharp pain (42%; 10/24), whereas premenopausal women more often felt gnawing and/or crampy pain (21%; 16/75) (p < 0.13). CONCLUSIONS: Postmenopausal women were twice as likely to experience pain during SCSH as premenopausal women were. Therefore, postmenopausal women might benefit from analgesia induced prior to the procedure. © 2015 Wiley Periodicals, Inc. J Clin Ultrasound 44:267-271, 2016.
