ABSTRACT
Objective:To evaluate the effectiveness of contrast-enhanced ultrasound in the differential diagnosis of atypical adenomyosis and fibroids using a decision tree model.Methods:The data of cases with difficulty in differentiating atypical adenomyosis from fibroids on conventional ultrasound examination at Shengjing Hospital of China Medical University from April 2021 to April 2022 were selected and analyzed. Ninety-five patients with contrast-enhanced ultrasound examination were finally selected, including 64 patients in the pathologically confirmed adenomyosis group and 31 patients in the fibroids group. The data from the qualitative analysis and the quantitative analysis of the time-intensity curve (TIC) curve were collected separately, including the temporal variability of contrast entry into the lesion, i.e.the difference between the time when the contrast agent started to enter the lesion and the time when the contrast agent finally filled the lesion completely. Indicators were first screened for inclusion in the decision tree model by univariate and multifactorial analyses, and decision tree models based on qualitative analysis indicators, and qualitative and TIC-based analyses were developed to further assess the diagnostic efficacy of both models.Results:Through the univariate analysis, it showed that the qualitative analysis indicators of lesion onset enhancement pattern, enhancement intensity, intra-lesion contrast distribution, and post-contrast lesion border were of statistical significance (all P<0.05) between the two groups. The differences in contrast arrive time (AT), contrast time to peak (TTP), |ΔAT|, and |ΔTTP| in the TIC curve analysis indexes were statistically significant between the two groups (all P<0.05). The difference in lesion temporal phase variability was statistically significant between the two groups ( P<0.05). After further screening by multifactorial analysis, the accuracy and misdiagnosis rates were 87.40% and (17.90±3.90)% in the qualitative analysis-based decision tree model respectively, and 90.50% and (21.10±4.20) % in the qualitative and TIC curve-based analysis decision tree model respectively. The ROC curves were plotted according to the two groups of models, and the areas under the curves were 0.915 and 0.931 respectively. Conclusions:A decision tree model based on ultrasonographic image analysis has diagnostic value for the differential diagnosis of atypical adenomyosis and uterine fibroids.
ABSTRACT
Objective:The decision tree Chi-square automatic interactive detection (CHAID) algorithm and binary Logistic regression analysis were used to construct the risk prediction model of premature ovarian failure (POF) in patients with uterine fibroids complicated with hypertension after surgery, and the results of the risk prediction model were compared and analyzed.Methods:Patients with uterine fibroids complicated with hypertension admitted to Taizhou Hospital of Zhejiang Province from Jan. 2019 to Sep. 2022 were retrospectively analyzed as the research objects. CHAID algorithm and Logistic regression analysis were used to establish risk prediction models, respectively. The area under the curve (AUC) of receiver operating characteristic curve (ROC) was used to compare and evaluate the prediction effects of the two models.Results:A total of 860 patients were collected, including 56 patients with premature ovarian function failure after operation, and the incidence of premature ovarian function failure was 6.51%. CHAID method and Logistic regression analysis showed that uterine myoma surgery, hypertension, smoking or passive smoking, family history of premature ovarian failure, sleep status, physical exercise and history of induced curettage were important influencing factors of premature ovarian failure. The accuracy of risk prediction of decision tree model was 88.2%, and the fitting effect of the model was good. The Logistic regression model Hosmer-Leme-show goodness of fit test showed that the model fit was good. The AUC of Logistic regression model was 0.893 (95% CI: 0.862-0.899), and the AUC of decision tree model was 0.882 (95% CI: 0.856-0.899). The predictive value of the two models was moderate, and there was no significant difference between them ( Z=0.254, P>0.05) . Conclusions:The combination of decision tree and Logistic regression model can find the influencing factors of premature ovarian function failure in patients with uterine fibroids complicated with hypertension after operation from different levels, and the relationship between the factors can be more fully understood. The establishment of a risk model for premature ovarian function failure in patients with uterine fibroids complicated with hypertension after surgery can provide a reference for postoperative intervention in patients with uterine fibroids complicated with hypertension, and more effectively help patients actively prevent and slow down the occurrence and development of POF.
ABSTRACT
To study the histomorphological spectrum of uterine leiomyoma variants. This study is done over a period of three year (May 2019 to May 2022) in the Department of Pathology, LNMC, Bhopal. Total of 316 hysterectomy and 14 myomectomy specimens were studied. Specimens were fixed in formalin and paraffin embedded. H&E stained tissue sections were studied. In the study we performed retrospective analysis of hysterectomy and myomectomy specimen and 330 cases of leiomyoma were evaluated. Among 330 cases, 316(95.75%) were hysterectomy specimen for varying indication and 14(4.24%) were myomectomy specimen. Histologically the usual leiomyomas was comprising of 164(49.69%) cases followed by hyalinised leiomyoma 70(21.21%), myxoid leiomyoma 15(4.54%), hydropic change 12(3.63%), cellular 11(3.33%), lipoleiomyoma 10(3.03%), calcification 10(3.03%), infarct type necrosis 10(3.03%), mitotically active 8(2.42%), symplastic 7 (2.12%), schwanonian 6(1.81%), epithelioid 3(0.90%), dissecting leiomyoma 2 (0.60%) and stromal metaplasia (osseous and cartilaginous) 2(0.60%). Leiomyoma is the commonest benign smooth muscle tumor of the uterus with a number of histological variants. In this study conventional leiomyoma being the commonest variant followed by hyalinized leiomyoma, myxoid leiomyoma, hydropic leiomyoma and lipoleiomyoma. It is important to categorise various types of leiomyoma on histology to avoid misdiagnosis.
ABSTRACT
Objective:To investigate the safety and efficacy of ultrasound-guided transversus abdominis plane (TAP) combined with paracervical block in percutaneous microwave ablation(PMWA) of uterine fibroids.Methods:Twenty-four patients with uterine fibroids who underwent PMWA after ultrasound-guided TAP combined with paracervical block in Sichuan Cancer Hospital from October 2021 to January 2022 were retrospectively analyzed. The success rate and adverse reactions of TAP combined with paracervical block were recorded, and the types and doses of rescue analgesics used during and after operation were recorded. The pain degree of patients was recorded by NRS(numeric rating scales) during and 30 minutes, 1 hour, 2 hours, 4 hours, 6 hours, 12 hours and 24 hours after operation, and the satisfaction of patients was recorded.Results:The success rate of TAP combined with paracervical block was 100%, and there were no adverse reactions during and after operation. During the operation, 5 patients(20.83%) had mild pain, which was tolerable and did not need intervention, 4 patients(16.67%) presented with moderate pain, and the NRS scores were 4, 4, 5 and 6 respectively, the symptoms were relieved after rescue analgesia. All patients completed one ablation, no ablation failure or secondary ablation. Some patients had mild pain after operation, which could be tolerated without intervention, and all were relieved naturally within 6 hours. All patients returned home on the day of ablation and were 100% satisfied with the analgesic effect.Conclusions:Ultrasound-guided TAP combined with paracervical block in PMWA of uterine fibroids is safe and effective, which is worthy of clinical promotion.
ABSTRACT
Objective To explore the risk factors for incident endometrial injury and 3-month endometrial injury after magnetic resonance-guided focused ultrasound(MRgFUS)ablation of uterine fibroids(UF). Methods UF patients who were diagnosed in Peking Union Medical College Hospital and underwent MRgFUS ablation in Amcare Women's and Children's Hospital from August 2016 to October 2020 were retrospectively enrolled in this study.Clinical data of 66 UF patients were collected and compared between endometrial injury group and non-injury group.Stepwise regression was employed to determine the risk factors for the incident endometrial injury and 3-month endometrial injury.Multivariate logistic regression analysis was performed to explore the relationship of endometrial injury with age,pre-ablation tumor size,multiple UF,International Federation of Gynecology and Obstetrics(FIGO)classification,T2WI signal intensity,and treatment time.Results In terms of incident endometrial injury,the 66 patients included 41(62.1%)cases with no injury,4 cases(6.1%) with grade 1 injury,5 cases(7.6%)with grade 2 injury,and 16 cases(24.2%)with grade 3 injury.In terms of 3-month endometrial injury,the 66 patients included 49 cases(74.2%)with no injury,5 cases(7.6%)with grade 1 injury,2 cases(3.0%)with grade 2 injury,and 10 cases(15.2%)with grade 3 injury.Stepwise regression analysis indicated that FIGO classification was significantly associated with incident endometrial injury(

Objective:To investigate the role of contrast-enhanced ultrasound (CEUS) features in preoperative screening of patients with uterine fibroids treated by magnetic resonance imaging guided focused ultrasound (MRgFUS).Methods:The preoperative CEUS features of 28 patients (32 lesions) with uterine fibroids treated by MRgFUS in Xijing Hospital of Air Force Military Medical University from January 2018 to March 2021 were analyzed. The relationships between the imaging features of lesions and the necrosis range were evaluated, which included echo intensity in gray-scale ultrasound, the patterns of the perfusion intensity, perfusion distribution, the contrast agent into the model, lesions with entangled branch vessels, ring-like enhancement, and perfusion regression.Results:The gray-scale ultrasound showed that 68.75%(22/32) lesions were hypoechoic. The CEUS showed that 81.25%(26/32) lesions were iso/hypo-enhancement, 65.63%(21/32) lesions were heterogeneous enhancement, 68.75%(22/32) lesions with entangled branch vessels, 71.88%(23/32) lesions with ring-like enhancement, and 75%(24/32) lesions with fast-out enhancement. The 6 indicators above-mentioned had effects on the non-perfusion volume ratio≥50%, the differences were statistically significant (all P<0.05). Conclusions:CEUS can evaluate the blood flow characteristics in uterine fibroids, providing important information for preoperative screening of uterine fibroids for MRgFUS ablation.
ABSTRACT
Objective:To explore the molecular mechanism of modified Guizhi Fulingwan in rats with uterine fibroids. Method:Seventy-two female adult SD rats of SPF grade were randomly divided into a model group， a normal group， and a preventive administration group. The model group and preventive administration group were established by estrogen and progestin loading method. After successful modeling， the rats in the model group were randomly divided into a western medicine group （mifepristone）， the high-dose traditional Chinese medicine（TCM） group， and a low-dose TCM group. All the rats were dosing as required once a day for 28 consecutive days. Hematoxylin-eosin（HE）staining was used to observe the morphological changes of the uterus. The micRNA gene chip was used to detect the expression profile of uterine micRNA gene. Differential expressions of micRNA were screened by bioinformatics methods. Gene function enrichment was used to predict the possible signaling pathways in rats with uterine fibroids by modified Guizhi Fulingwan. Result:Compared with the normal group， microRNA of the model group was 1 up-regulated and 9 down-regulated. Compared with the model group， microRNA of the high-dose group of TCM group was 2 up-regulated and 1 down-regulated， in the preventive administration group， 9 was up-regulated and 2 was down-regulated. Gene function enrichment analysis indicated that four signaling pathways were closely related to uterine fibroids. They were mitogen-activated protein kinase （MAPK） signaling pathway， Wnt signaling pathway， mammalian rapamycin target protein （mTOR） signaling pathway and vascular endothelial cell growth factor （VEGF） signaling pathway. Conclusion:Modified Guizhi Fulingwan affected the expression profile of micRNA in rat model of uterine fibroids induced by estrogen and progesterone， suggesting that modified Guizhi Fulingwan may involve in a variety of biological processes such as signal transduction and gene regulation in the treatment of uterine fibroids.
ABSTRACT
Background: Fibroid is the commonest benign tumor of the uterus and also commonest benign solid tumor in females. Fibroids are found to be 2-3 times more prevalent in obese women, specially the one’s with central obesity and in those with BMI > or = 35. Epidemiologic data also shows pregnancy is associated with reduced risk of fibroids. So, the present study will be a cross-sectional study which will be undertaken to know the association of uterine leiomyoma with BMI and parity in the women of coastal Karnataka.Methods: An analytical cross-sectional study was performed among the 100 patients attending OPD at the department of obstetrics and gynecology, Karwar institute of medical sciences from June 2018 to August 2018. Women suspected to have fibroid based on their symptoms were made to undergo ultrasonography. Comparison was made between the parity, body mass index of the patient and the size of the uterine fibroid visualized.Results: Out of 100 women studied 63 were nulliparous and 37 women were multiparous. Incidence of fibroid is inversely proportional to parity. When BMI < 18 only 6 women had fibroid, when BMI > 25, 57 women had fibroids and between 18-25 group 37 women were diagnosed with fibroid.Conclusions: The fibroid showed directly proportional association with BMI. Greater the BMI, more was the risk of fibroids. The fibroid showed inversely proportional association with parity. Greater the parity of the women lesser was her chances of being at risk of having fibroid.
ABSTRACT
Objective@#To explore the application value of 3.0 T MultiVane XD (MVXD) technique in female patients with uterine adenomyosis and fibroids.@*Methods@#Patients diagnosed with uterine fibroids with ultrasound and suspected of adenomyosis were involved prospectively from March to May 2018, 3.0 T pelvic MRI examinations were performed during peri-ovulatory period. Axialconventional turbo spin echo (TSE) T2WI, axial MVXD T2WI, sagittal conventional TSE T2WI and MVXD sagittal T2WI were acquired. Two observers rated those 4 series in the aspects of sharpness of uterine border, motion artifacts, identification capability of lesions, confidence of diagnosis and overall image quality. Cohen Kappa analysis was used to evaluate the consistency of scores between 2 observers. Scores of TSE T2WI and MVXD T2WI qualities were compared using Wilcoxon matched-pairs signed-ranks test.@*Results@#Twenty patients were enrolled. Axial conventional TSE T2WI, axial MVXD T2WI were aquired on all of them. Sagittal conventional TSE T2WI, sagittal MVXD T2WI were aquired on 19 among them. Nine patients had only obvious adenomyosis, 6 had only uterinefibroids, and 5 had adenomyosis and uterine fibroids. Compared to conventional TSE technique, scores of two observers in the sharpness of uterine border, motion artifacts, and overall image quality is higher by MVXD with significant difference (P<0.05). The Kappa values for image quality scores of two observers ranged from 0.615 to 0.971, the agreement was good or very good.@*Conclusion@#Applying MVXD T2WI technique to patients with uterine fibroids and adenomyosiscould improve image quality, without sacrificing the ability to recognize and diagnose lesions, compared to conventional TSE T2WI technique.
ABSTRACT
RESUMEN El cáncer de mama puede originar de forma muy excepcional metástasis en órganos genitales. Estas suelen presentarse de forma asintomática siendo su diagnóstico generalmente tardío. En el estudio de la enfermedad diseminada la tomografía de emisión de positrones con fluordeoxiglucosa asociada a la tomografía computada (FDG PET/CT) juega un rol importante, sin embargo presenta limitantes al momento de diferenciar entre lesiones secundarias, primarias y neoplasias benignas que pueden tener elevada captación de fluordeoxiglucosa (1). Por lo expuesto anteriormente el diagnóstico de certeza solo puede realizarse mediante el estudio anatomopatológico. El caso presentado a continuación abarca uno de los posibles diagnósticos diferenciales con FDG PET/CT que evidencia un incremento en la captación de fluordeoxiglucosa.
ABSTRACT Breast cancer rarely metastasize on pelvic organs and its diagnosis is often delayed due to the asymptomatic nature of this disease. Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography (FDG PET/CT) is a useful method for early diagnosis. However, may present a false positive diagnosis from benign lesions that have an increased uptake of glucose. We present a case in which a patient who had breast cancer had an increase glucose uptake in FDG PET/CT from a benign lesion.

Background: The “window of implantation” (WOI) is a transient but well defined period during which the hostile endometrial lining is transformed to a surface receptive to accept the embryo. Recently, data are beginning to accumulate suggesting negative influence of non-cavity distorting intramural uterine fibroids (NCD-IMF) on endometrial receptivity that may have implications for implantation failure. However, molecular mechanisms underlying infertility associated with NCD-IMF remain unclear. The aim of present study was to examine the expression and cellular distribution of insulin-like growth factor 1 receptor (IGF1R) during WOI in infertile women with NCD-IMF and fertile controls. While, reports are available that support role of IGF1R in mediating adhesive interaction with the implanting blastocyst, the effect of NCD-IMF on IGF1R expression during the WOI is not defined.Methods: Quantitative real-time polymerase chain reaction and immunohistochemistry were used to evaluate messenger RNA (mRNA) and protein expression of IGF1R in midsecretory endometrial biopsies obtained from infertile women with NCD-IMF (n=20) and healthy fertile controls (n=10).Results: As compared to fertile controls, significantly higher IGF1R: i) mRNA levels (1.59 fold up regulation; p=0.044) and ii) immunoscore in the luminal epithelium (8.94±3.13 versus 6.31±1.49; p=0.009) were observed in infertile women with NCD-IMF.Conclusions: Over expression of IGF1R in infertile women with NCD-IMF, during the window of receptivity, may result in altered ability of uterine epithelial cells for blastocyst adhesion and subsequent implantation, which might lead to poor reproductive outcome in these women.
ABSTRACT
Background: The aim of the study was to assess the feasibility, safety and efficacy of performing myomectomy during cesarean section.Methods: It was prospective study conducted in Sri Guru Ram Das University of Health and sciences which is a tertiary care referral centre. Myomectomy was conducted in 34 pregnant women during elective or emergency cesarean section. Analysis was done with reference to age, parity, character of myomas, intraoperative and post-operative morbidity, duration of surgery and duration of stay in hospital.Results: In this study 34-58 fibroid of various size (2-14 cm) were removed in 34 patients during cesarean section. Majority of fibroids were located in body of uterus (65.5%) and in anterior wall (55.2%) and all them were sub serosal. No significant difference was found in mean preoperative hemoglobin (11.8±0.7) and postoperative hemoglobin (10.9±0.8). No patient had postpartum hemorrhage requiring cesarean hysterectomy. Only two patient needed blood transfusion postoperatively. Mean time taken for surgery was 58.4±8.94 minute and average duration of hospital stay was 6.7±1.6.Conclusions: With the advent of better anesthesia, easy availability of blood and blood component, cesarean myomectomy is safe surgical procedure when performed by experienced obstetrician in carefully selected patients.
ABSTRACT
OBJECTIVE: To investigate the effect of high intensity focused ultrasound(HIFU)on pregnancy outcomes inpatients with uterine fibroids.METHODS:From October 2010 to October 2017,241 patients with uterine fibroids whowere pregnant after HIFU treatment in Suining Central Hospital and Chongqing Haifu Hospital were retrospectivelyanalyzed.The efficacy of HIFU ablation and the patient′s pregnancy outcomes were investigated.RESULTS:Among thesepatients,9 of them were conceived within 2 month after HIFU,24 were conceived between 2 and 4 months after HIFU,33 patients were conceived between 4 and 6 months,and 175 patients were conceived after 6 months of HIFU treatment.The median conception time was 9 months after HIFU(range:1 to 26 months).Among them,152 patients had deliveredbabies successfully,12 patients are still in pregnancy,3 patients had ectopic pregnancy,2 patients had incisionalpregnancy,72 patients had abortions,including 66 cases of induced abortion and 6 cases of spontaneous abortion.Causesof induced abortion included:embryonic development stopping(8 cases),increased vaginal bleeding(5 cases),hypothyroidism(1 case),use of drugs during pregnancy and being fear of fetal malformation(6 cases),and unplannedpregnancy(52 cases).Of the 152 patients who had delivered,147 had 148 full-term deliveries(1 had full-term deliverytwice)and 5 had preterm birth.No uterine rupture occured during pregnancy or childbirth,and the newborn is healthy.Before HIFU treatment,136 of 241 patients had a history of abnormal pregnancy,and only 17 of these patients hadabnormal pregnancy after HIFU treatment.The incidence of spontaneous abortion in patients after HIFU treatment wassignificantly lower than before treatment(P<0.05).CONCLUSION:HIFU is a safe and effective treatment for patients whowish to have children.It can also improve the fertility of patients with a history of abnormal pregnancy,with no additionalobstetric risks.
ABSTRACT
OBJECTIVE: To study the characteristics and clinical application of radical laparoscopic myomectomy.METHODS: Retrospectively analyze the clinical data of 31 patients with uterine leiomyomas undergoing laparoscopic radical myomectomy at the Department of Obstetrics and Gynecology,the First Affiliated Hospital of Soochow University,from January 2016 to December 2018.The surgical indications,operation time,intraoperative blood loss,postoperative menstrual recovery,postoperative uterine fibroid recurrence rate and postoperative sexual and life quality change indicators were analyzed.RESULTS: All patients were with multiple uterine fibroids(averaged 42.6±3.5 years),and all of them received successful operation.There were no patients who underwent laparotomy or hysterectomy.The postoperative fibroids residual rate among the 31 patients was 3.23%(1 case).The recurrence rate of postoperative uterine fibroids half a year later was 9.68%(3 cases).Five patients has no significant change in postoperative menstruation volume while the other 25 patients had volume reduction(t=8.614,P0.05).Only one patient suffered from hot flashes,night sweating and other menopausal symptoms.WHOQOL-BREF scale was used for patients to assess preoperative and postoperative quality of life,and there were obviously improved psychological and physiological score in patients after operation(P<0.05).CONCLUSION: For women with multiple uterine fibroids who have surgical indications and a strong desire to retain the uterine but have no fertility requirements,radical laparoscopic myomectomy may be the most effective surgical therapy,which can achieve the purpose of surgical treatment,improving the resection rate,and maintaining low postoperative recurrence rate,preserving menstruation and the function of uterus and ovary,and increasing the sexual life quality.

ABSTRACT
Abstract Objective There are no published studies analyzing the quality of the information for lay women on the Internet regarding uterine fibroids. The accuracy of the provided material is also unknown. Thus, we have performed a cross-sectional study with 381 websites in the English and Brazilian Portuguese languages between May and December 2017. Methods Two investigators performed the analysis, and the Cohen kappa coefficient was calculated to analyze the agreement between them. Search terms (uterine fibroids and derivatives) in the English and Brazilian Portuguese languages were used. The accuracywas analyzed by a 10-itemchecklist created based on the American Society for Reproductive Medicine (ASRM), National Institutes of Health (NIH) and European Menopause and Andropause Society (EMAS) consensuses about uterine fibroids. The item-test correlation and the intraclass coefficient were performed in the 16 questions from the DISCERN instrument, which was designed to measure the quality of health information on the Internet. Analysis of variance (ANOVA) measurements were performed for the independent variables and the DISCERN/accuracy scores. Results Google was the most used search engine, and uterine fibroid was the search term that generatedmost of the analyzed material. The median score for accuracy in all websites was 5 out of 10, and the median score of the DISCERN instrument was 38 out of 80. The top-scoring sites in the English language were derived from scientific organizations and federal governments, and they regarded the DISCERN score (The American College of Obstetricians and Gynecologists [ACOG], the Food and Drug Administration [FDA]) and the accuracy criteria (NIH, and FDA). On the other hand, in the Brazilian Portuguese language, the highest scores in both instruments were from magazines or physician's blogs. The Cronbach α test showed a higher correlation (0.77-0.79) between the sites and DISCERN; however, the item-test correlation varied from 0.39 to 0.56. Conclusion There is a need to improve the quality of the information regarding uterine fibroids for lay women.
Resumo Objetivos Não existem estudos publicados analisando a qualidade de informação para mulheres leigas na internet sobre o leiomioma uterino. A acurácia do material existente também não é conhecida. Portanto, realizamos um estudo transversal envolvendo 381 sites em língua inglesa e portuguesa de maio a dezembro de 2017. Métodos Dois pesquisadores fizeram a análise, e o coeficiente kappa de Cohen foi calculado para analisar a concordância entreambos. Termos de pesquisa (leiomioma uterino e derivados)eminglês e português foramusados. A acurácia foi analisada por meio de uma lista de 10 itens criados após a fusão de consensos da Sociedade Americana de Medicina da Reprodução (ASRM, na siglaeminglês), dos InstitutosNacionais de Saúde (NIH, na siglaem inglês) e da Sociedade Europeia de Menopausa e Andropausa (EMAS, na sigla em inglês) sobre leiomioma uterino. A correlação item-teste e o coeficiente intraclasse foram realizados nas 16 questões do questionário DISCERN, um instrumento desenvolvido para medir a qualidade da informação de saúde disponível na internet. O método de análise de variância (ANOVA, na sigla em inglês) foi utilizado para as variáveis independentes e as pontuações de acurácia e do DISCERN. Resultados O Google foi a ferramenta mais utilizada, e o leiomioma uterino foi o termo de busca que gerou a maior parte do material analisado. A pontuação média para a acurácia dos websites foi 5/10, e do questionário DISCERN, 38/80. Os sites de língua inglesa commaior pontuação foram os de organizações científicas e de governos federais, tanto no questionário DISCERN (Faculdade Americana de Obstetrícia e Ginecologia [ACOG, na sigla em inglês], Administração de Alimentos e Medicamentos [FDA, na sigla em inglês]) quanto na acurácia (NIH e FDA). Entretanto, em língua portuguesa, os sites com as maiores pontuações em ambos os instrumentos foram de revistas ou blogs médicos. O teste α de Cronbach evidenciou maior correlação entre os sites e o DISCERN (0,77-0,79); contudo, a correlação item-teste variou de 0,39 a 0,56. Conclusão Há necessidade demelhorar a qualidade da informação sobre o leiomioma uterino para mulheres leigas.
