“…In pregnancy, it is widely utilized to analyze em-ORIGINAL ARTICLE bryonic and fetal anatomy at the first trimester (1) and to evaluate the biometry and morphology of the uterine cervix in more advanced gestations (2) , demonstrating to be an excellent predictor of preterm delivery (3) . It leaves no doubts about the benefit of evaluating adnexal masses (4) , including deep endometriosis and its intestinal involvement -with effectiveness comparable to magnetic resonance imaging (5) .…”

Objective: To comparatively evaluate the effectiveness of transvaginal ultrasonography (TVUS) and sonohysterography (SHG) in the assessment of endometrial diseases in women with abnormal uterine bleeding. Materials and Methods: Cross-sectional study with 30 patients, aged from 29 to 71 years, 21 (70%) of them premenopausal and 9 (30%) postmenopausal. Saline solution (at 9%) was utilized as contrast agent for SHG. The MacNemar test was utilized for comparison of diagnostic studies. Results: Hysteroscopy diagnosed 18 cases (60%) of intracavitary alterations, and 10 polyps (33.3%). TVUS demonstrated 83.3% sensitivity and specificity, and SHG showed 94.4% sensitivity and 91.6% specificity. The MacNemar test showed similar sensitivity (p = 0.500) and specificity (p = 1.000) between TVUS and SHG in the detection of endometrial diseases. In the diagnosis of polyp, SHG showed the highest sensitivity (90.9% vs. 27.3%; p = 0.016) with similar specificity (89.5% vs. 94.7%; p = 1.000). Conclusion: SHG and TVUS present a good predictive value for endometrial diseases in patients with abnormal uterine bleeding. SHG and TVUS present similar sensitivity and specificity in the detection of such diseases, but SHG is more sensitive in the detection of polyps.

Materiais e Métodos: Estudo transversal com 30 pacientes, idade entre 29 e 71 anos, 21 delas (70%) na pré-menopausa e 9 (30%) na pós-menopausa. Utilizou-se solução salina a 0,9% para contraste na HSG. Foi considerado o achado histeroscópico e/ou histopatológico como método padrão. Utilizou-se o teste de MacNemar para comparação dos testes diagnósticos. Resultados: A histeroscopia diagnosticou 18 casos (60%) de alterações intracavitárias, sendo 10 pólipos (33,3%). A USTV apresentou sensibilidade e especificidade de 83,3% e a HSG mostrou sensibilidade de 94,4% e especificidade de 91,6%. O teste de MacNemar evidenciou sensibilidade (p = 0,500) e especificidade (p = 1,000) semelhantes entre a USTV e a HSG para detecção de alterações endometriais. No diagnóstico de pólipo, a HSG apresentou maior sensibilidade (90,9% × 27,3%; p = 0,016), com especificidade semelhante (89,5% × 94,7%; p = 1,000). Conclusão: A HSG e a USTV apresentam boas taxas de predição para doenças endometriais em pacientes com sangramento uterino anormal. A HSG apresenta sensibilidade e especificidade semelhantes às da USTV na detecção dessas doenças, porém apresenta sensibilidade maior para pólipos.

Aim: The purpose of this article is to show the use and utility of mersilene tape in medical procedures, such as transabdominal cerclage (TAC). Material and methods: Based on their biomechanical properties, we present our experience with mersilene tape used as treatment for cervical incompetence. Cervical insufficiency or cervical incompetence is defined as asymptomatic cervical shortening and dilatation with the absence of detectable uterine contractions. The mechanical properties of cervical tissue are derived from its extracellular matrix and its most important constituent the fibrillar collagen, alongside other constituents such as proteoglycans, hyaluronic acid, elastin, and water. In the absence of the uterine contractions, the cervix is loaded by intrauterine pressure (including the weight of the growing fetus and amniotic sac), the gravity as well as passive pressure from the uterine wall. These forces also depend on the support action of pelvic floor structures and abdominal wall. The static load resulting from the combination of uterine growth, hydrostatic pressure and gravity seems to be the dominant determinants that cause cervical shortening. The placement of the mersilene tape acts as a barrier between the intrauterine pressure and the cervix. The main advantage of the TAC procedure is the placement of the nonabsorbable suture (mersilene tape at the level of the internal os, avoiding the placement of a vaginal foreign body and subsequently increasing the risk of ascending lower genital tract infection, decreased incidence of slippage, and the ability to leave the stitch in place between pregnancies. Results: The follow-up was without complications regarding the pregnancies treated with transabdominal cerclage. None of the pregnancies terminated prematurely as related to the presence of the tape, but it necessitates to be performed a caesarean section for delivery. Conclusions: Mersilene tape is safe and useful in different medical procedures, including transabdominal cerclage during pregnancy.
