Evaluation of Comt2, Comt3, Cyp1b1, and Esr1 gene polymorphisms as risk factor for endometrial polyp.

The aim of this study is to evaluate COMT2, COMT3, CYP1B1, and ESR1 gene polymorphisms and occurrence of endometrial polyps. In addition, we intended to evaluate the clinical and epidemiological features of patients with and without the presence of the disease, characterizing the possible risk factors. A cross-sectional study was performed, with a total of 309 women, including 236 in the group of women with endometrial polyp confirmed by hysteroscopy and anatomical pathological examination and 73 in the group of people with diagnostic hysteroscopy without abnormal findings from the macroscopic point of view. Polymorphisms of four genes were studied: COMT2 (rs4680), COMT3 (rs5031015), CYP1B1 (rs1056836), and ESR1 (rs2234693). Polymorphism genotyping was determined using real-time polymerase chain reaction. Considering the results, no differences were identified between the two groups with respect to age, body mass index, diabetes, dyslipidemia, or smoking. The group of women without endometrial polyps showed higher use of hormone therapy than the other group (16.4 percent versus 3.8 percent, p < .001). The COMT2, COMT3, CYP1B1, and ESR1 genes exhibited no significant difference for the occurrence of endometrial polyp between the two groups. The research concluded that no correlation was identified between the genetic polymorphisms evaluated and the presence of endometrial polyps.

Association of IGF-1 CA(n) and IGFBP3 rs2854746 Polymorphisms with Endometrial Polyp Risk.

INTRODUCTION: Insulin-like growth factor 1 (IGF-1) is a peptide growth factor that promotes cell proliferation and inhibits apoptosis. The bioavailability of IGF-1 is regulated by the insulin-like growth factor binding protein 3 (IGFBP3). Genetic variations influence the levels of IGF-1 and IGFBP3. The purpose of this study was to examine the association of polymorphisms IGF-1 CA(n) and IGFBP3 rs2854746 with risk of endometrial polyps. MATERIALS AND METHODS: Case control observational study, composed of 104 women with antecedent of endometrial polyp (case group) and 81 postmenopausal women without antecedent of endometrial diseases (control group). Genotyping of IGF-1 CA(n) was performed by PCR and fragment analysis by capillary electrophoresis, and genotyping of IGFBP3 rs2854746 was performed by PCR-HRM. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated by logistic regression. RESULTS: The genotype IGF-1 CA(19)/CA(19) was associated with an increased endometrial polyp risk (OR=2,57; IC 95%= 1,09 - 6,01); this was also found when combining it with CA(>19)/CA(n) genotypes (OR=2,18; IC 95%= 1,06-4,47). The IGFBP3 rs2854746 analyses showed the CG genotype having a protective effect for endometrial polyp (OR=0,37; IC 95%= 0,19-0,73), fact also observed when grouping CG and GG carriers (OR=0,51; IC 95%= 0,28-0,93). CONCLUSION: The genotypes CA(19)/CA(19) and CA(19)/CA(19) + CA(>19)/CA(n) of the IGF-1 CA(n) may be considered a risk for endometrial polyp, whereas the genotypes CG and CG + GG of IGFBP3 rs2854746 polymorphism have an inverse effect of endometrial polyp risk.

Differential Diagnosis between Bartholin Cyst and Vulvar Leiomyoma: Case Report.

Genital leiomyomas are rare tumors that can often be misdiagnosed as Bartholin cyst. We report a case of a 32-year-old patient who had a cystic nodulation in the left labium majus that was suggestive of Bartholin cyst. A resection surgery was performed, and the definitive histopathology diagnosis was vulvar leiomyoma. The macroscopic features of cystic lesions difficult the differential diagnosis between leiomyoma and Bartholin cyst; therefore, a histopathologic examination is often recommended.

Os leiomiomas genitais são tumores raros, e frequentemente são diagnosticados como cisto de Bartholin. Relatamos o caso de uma paciente de 32 anos em que ocorreu nodulação cística no grande lábio esquerdo sugestiva de cisto de Bartholin. Uma cirurgia de ressecção foi realizada, e o diagnóstico histopatológico definitivo foi leiomioma vulvar. As características macroscópicas das lesões císticas dificultam o diagnóstico diferencial entre o leiomioma e o cisto de Bartholin, de modo que o exame histopatológico é frequentemente recomendado.

Repercussions of digoxin, digitoxin and estradiol on the endometrial histomorphometry of oophorectomized mice.

The digitalics (digoxin and digitoxin) have an estrogenic action, confirmed by the presence of gynecomastia observed in men who are users of steroids, and it is also confirmed by the increase of vaginal trophism in postmenopausal female users, although little is known about the endometrium. These effects might result from the similarity of the chemical structures between the digitalics and estrogens. This study evaluated 27 female mice. Twenty-four mice were oophorectomized and in three of them the ovaries were manipulated, but they were not extirpated. Forty days after the surgery each group of three animals received a medication with a specific drug (digoxin, digitoxin or estradiol) for 2 weeks. Twenty-four hours after the last medication, all the animals were hysterectomized and the wombs were processed, cut and put on laminae. By histomorphometry, we analysed the area of the transverse sections of the endometrium, the area of the endometrial glands and the height of the uterine epithelium. The respective averages and the standard deviations were calculated. The results showed that digoxin neither presented an estrogenic action (p > 0.05) nor raised the power of the estradiol action (p > 0.05). Digitoxin promoted an estrogenic action on the glandular area (p < 0.05), and also raised the power of the estradiol action on the transverse section of the endometrium and on the glandular area (p < 0.05).

Abordagem laparoscópica do câncer de endométrio / Laparascopic approach to endometrial cancer

Objetivo: apresentar uma nova abordagem laparoscópica para tratamento do câncer de endométrio. Métodos: de fevereiro de 1996 à fevereiro de 1998, doze pacientes com câncer de endométrio, diagnosticadas por histerocopia e biópsia, foram submetidas a linfadenectomia pélvica associada à histerectomia e salpingooforectomia por laparacospia. A média de idade das pacientes foi de 58,1 anos; o número médio de gestaçöes foi 2,3 e o índice de massa corpórea médio foi de 28,6. Resultados: o tempo anestésico médio foi de 4,8 horas. O tempo médio de internaçäo foi de 3,3 dias. O número total de linfonodos retirados foi de 176, sendo 104 (59,1 por cento) do lado direito e 72 (40,9 por cento) do lado esquerdo. Näo foram encontrados linfonodos comprometidos. O número médio de linfonodos retirados por paciente foi de 18,5. Foram observados duas complicaçöes: em um caso houve necessidade de abandonar o procedimento por aumento da pressäo endotraqueal e uma das pacientes evluiu com formulaçäo de granuloma em cúpula vaginal. Conclusöes: nesta avaliaçäo preliminar dos resultados de histerectomia total com anexectomia bilateral e linfadenectomia laparoscópica para tratamento do câncer de endométrio, obtivemos resultados satisfatórios quanto ao estadiamento na neoplasia ao número de linfonodos retirados e quanto àa complicaçöes cirúrgicas observadas.
