The role of laparoscopy in the propaedeutics of gynecological diagnosis1.

PURPOSE: To evaluate agreement between pre- and post-laparoscopy gynecological diagnosis in order to demonstrate the rationality of this minimally invasive technique use in gynecological propaedeutics. METHODS: Retrospective chart review study conducted between March 2010 and October 2016 based on a convenience sample. 315 patients undergoing surgical laparoscopy at the Center of Gynecologic Endoscopy and Family Planning of Botucatu Medical School/UNESP. Pre- and postoperative diagnoses were compared by the diagnosis agreement test considering the proportions of events. RESULTS: Laparoscopy contributed to diagnosis in 59.6% of infertility cases (P>0.05), in 93.7% of chronic pelvic pain of undetermined origin (P<0.01) and conclusively elucidated the diagnosis of acute abdomen and the ruling out of tubo-ovarian abcess (P<0.05). Laparoscopy also increased the diagnosis of pelvic-abdominal adhesions in 76.7% (P>0.05). CONCLUSION: The use of laparoscopy considerably contributed to diagnostic elucidation, especially in cases of undetermined chronic pelvic pain.

Concomitant p53 and PTEN immunoexpression to predict the risk of malignancy in endometrial polyps.

The aim of this retrospective cross-sectional study was to assess the usefulness of phosphase and tensin homolog deleted on chromosome 10 (PTEN) and p53 protein immunoexpression in predicting the risk of malignancy in endometrial polyps. The study was conducted at tertiary public hospital, university teaching center, and private practice clinic.A total of 159 patients with endometrial polyps who underwent hysteroscopic polypectomy between January 2010 to December 2014 were included. p53 and PTEN immunoexpression were assessed in histologic endometrial polyp samples. Patients were allocated into 2 groups: group A, endometrial polyps without atypia (120), and group B, endometrial polyps with atypia (39), which were subdivided into A1 (80) and B1 (21) = p53-/PTEN+ immunostaining; A2 (20) and B2 (11) = p53+/PTEN+; A3 (14) and B3 (4) = p53+/PTEN-; A4 (6) and B4 (3) = p53-/PTEN-.There was no significant difference between groups regarding clinical and epidemiologic parameters, except for age. Neoplasia incidence within groups was higher when at least 1 marker was abnormally stained (in group A, P = .0089, odds ratio [OR] = 13.94 [1.62; 120.27]; in group B, P = .0255, OR 12.73 [1.38; 117.27]). Overall neoplasia incidence was higher in group B than in group A (20.5% vs 5.8%; P = .0113). Malignant neoplasia was found more frequently in patients with p53+ (P = .0006, OR = 7.67 [2.30; 25.54]) and PTEN- (P = .0043; OR = 5.43 [1.77; 16.61]).Immunohistochemical analysis using p53 and PTEN as markers, either alone or concomitantly, can be useful to predict malignant transformation in cases of endometrial polyps.

Immunohistochemical expression of hormone receptors, Ki-67, endoglin (CD105), claudins 3 and 4, MMP-2 and -9 in endometrial polyps and endometrial cancer type I.

OBJECTIVE: The aim of this study was to investigate the malignant potential of endometrial polyps (EP) by assessing the immunoexpressions of both estrogen receptor (ER) and progesterone receptor (PR), Ki-67 cell proliferation index, neovascularization network (endoglin - CD105), cellular adhesion molecules (claudins 3 and 4), and extracellular matrix proteins (MMP-2 and -9) in both EP and endometrioid adenocarcinoma (type I) in comparison with the normal endometrium. STUDY DESIGN: This is a cross-sectional comparative study. Patients were identified from the database of Botucatu Medical School, São Paulo State University (BMS-UNESP) Clinical Pathology Laboratory. SETTING: The study was conducted using a convenience sample of patients attending the Sectors of Gynecologic Endoscopy and Family Planning and Gynecologic Oncology of the Department of Gynecology and Obstetrics of BMS-UNESP, Brazil. PATIENTS: A total of 90 women were allocated into the following three groups: EP without atypia (EP, n=30), endometrioid endometrial cancer (EC, n=30), and normal endometrium (control, n=30). METHODS: Epidemiological and clinical data were obtained by reviewing medical records. Adenocarcinoma and control cases were assessed using the tissue microarray technique. The immunoexpressions of ER, PR, Ki-67, CD105, claudins 3 and 4, and MMP-2 and -9 were assessed in paraffin blocks containing sections of the largest polyploid lesion fragment and tissue microarray recipient blocks. MAJOR RESULTS: Compared to the control group, significant differences in the expression of ER (P<0.001), PR (P<0.05), Ki-67 (P<0.001), CD105 (P<0.001), and claudin 3 (P<0.001) were observed in EP and EC. No significant differences were found between EP and EC (P≥0.05). MMP-2 and -9 expression were nearly absent in all groups. CONCLUSION: The malignant potential of EP could not be determined through the immunohistochemical parameters used in this study. No MMP-2 or -9 expression was observed in any endometrial tissue sample. Further studies are necessary for a better understanding of the biomolecular mechanisms underlying endometrial carcinogenesis.

The value of hysteroscopic biopsy in the diagnosis of endometrial polyps.

Several studies have demonstrated that the combination of hysteroscopy with endometrial biopsy is more accurate in differentiating endometrial polyps from endometrial hyperplasia and cancer. However, blind biopsy not always confirms hysteroscopic findings due to high rates of inadequate or insufficient material. The objective of this clinical, prospective, and comparative study was to establish a correlation between the histological results of office-based endometrial biopsies (hysteroscopically guided and blind) with the surgical polypectomy specimens. We evaluated 82 patients with hysteroscopic diagnosis of endometrial polyp, who randomly underwent hysteroscopically guided biopsy or blind biopsy, referred for surgical resection. A total of 36 women (43.9%) underwent hysteroscopically guided biopsy and 46 women (56.1%) underwent blind biopsy. The sensitivity of hysteroscopically guided biopsy for the diagnosis of endometrial polyps ranged between 35.3 and 36.8%, when carried out at the apex and base of the lesion, compared with 29.2% for blind biopsy. Specificity was 33.3, 50, and 60%, respectively, for each biopsy. The positive predictive values were 75, 77.8, and 87.5%, and negative predictive values were 8.3, 14.3, and 8.1% respectively, compared with surgical polypectomy specimens. The office-based endometrial biopsies had low diagnostic accuracy for endometrial polyps compared with surgical polypectomy specimens.

Clinical and psychological repercussions of videolaparoscopic tubal ligation: observational, single cohort, retrospective study / Repercussões clínicas e psíquicas da ligadura tubária videolaparoscópica: estudo observacional de coorte única, retrospectivo

CONTEXT AND OBJECTIVE: Tubal ligation is one of the most commonly used contraceptive methods worldwide. Since the controversy over the potential effects of tubal sterilization still continues, this study aimed to evaluate the clinical and psychological repercussions of videolaparoscopic tubal ligation. DESIGN AND SETTING: Observational, single cohort, retrospective study, conducted in a tertiary public hospital. METHODS: A questionnaire was applied to 130 women aged 21-46 years who underwent videolaparoscopic tubal ligation by means of tubal ring insertion or bipolar electrocoagulation and sectioning, between January 1999 and December 2007. Menstrual cycle interval, intensity and duration of bleeding, premenstrual symptoms, dysmenorrhea, dyspareunia, noncyclic pelvic pain and degree of sexual satisfaction were assessed in this questionnaire. Each woman served as her own control, and comparisons were made between before and after the surgical procedure and between the two techniques used. RESULTS: The clinical and psychological repercussions were significant, with increases in bleeding (P = 0.001), premenstrual symptoms (P < 0.001), dysmenorrhea (P = 0.019) and noncyclic pelvic pain (P = 0.001); and reductions in the number of sexual intercourse occurrences per week (P = 0.001) and in libido (P = 0.001). Women aged ≤ 35 years at the time of sterilization were more likely to develop menstrual abnormalities. The bipolar electrocoagulation method showed greater clinical and psychological repercussions. CONCLUSION: Regardless of the technique used, videolaparoscopic tubal ligation had repercussions consisting of increased menstrual flow and premenstrual symptoms, especially in women aged ≤ 35 years, and also had a negative influence on sexual activity. .

CONTEXTO E OBJETIVO: A ligadura tubária é um dos métodos contraceptivos mais utilizados em todo o mundo. Como a controvérsia sobre seus possíveis efeitos ainda continua, o objetivo deste estudo foi avaliar as repercussões clínicas e psíquicas da laqueadura videolaparoscópica. TIPO DE ESTUDO E LOCAL: Estudo observacional de coorte único, retrospectivo, conduzido em hospital público terciário. MÉTODOS: Foi aplicado um questionário a 130 mulheres, entre 21-46 anos, submetidas à ligadura tubária videolaparoscópica, pelas técnicas de eletrocoagulação bipolar/secção ou inserção do anel tubário, entre janeiro de 1999 e dezembro de 2007. Nesse questionário avaliou-se: intervalo do ciclo menstrual, intensidade e duração do sangramento, sintomas pré-menstruais, dismenorreia, dispareunia, dor pélvica não cíclica e grau de satisfação sexual. Cada mulher serviu como seu próprio controle, foi realizada análise comparativa entre os períodos pré- e pós-cirúrgico e entre as duas técnicas utilizadas. RESULTADOS: As repercussões clínicas e psicológicas mostraram-se significativas, com aumento de sangramento (P = 0,001), de sintomas pré-menstruais (P < 0,001), dismenorreia (P = 0,019), dor pélvica não cíclica (P = 0,001), e redução no número de relações sexuais por semana (P = 0,001) e na libido (P = 0,001). Mulheres com idade ≤ 35 anos, no momento da laqueadura, mostraram-se mais propensas a desenvolverem alterações menstruais. A técnica de eletrocoagulação bipolar mostrou maiores repercussões clínicas e psíquicas. CONCLUSÃO: A ligadura tubária videolaparoscópica, independentemente da técnica, repercutiu com ...

Usefulness of clinical, ultrasonographic, hysteroscopic, and immunohistochemical parameters in differentiating endometrial polyps from endometrial cancer.

STUDY OBJECTIVE: To evaluate the usefulness of clinical, ultrasonographic, hysteroscopic, and immunohistochemical parameters in differentiating endometrial polyps from endometrial cancer. DESIGN: Cross-sectional study (Canadian Task Force classification II-2). SETTING: Tertiary public hospital, university teaching center. PATIENTS: Eighty-two women who underwent hysteroscopic polypectomy and 20 women who underwent surgery to treat endometrial cancer. INTERVENTIONS: Analysis of medical records and immunohistochemical assessment of estrogen receptors, progesterone receptors, and endothelial markers CD34 and CD105. MEASUREMENTS AND MAIN RESULTS: Among women with endometrial cancer and endometrial polyps, respectively, mean age was 63 and 57 years (p = .01), 89% and 67% were postmenopausal (p < .05), and 85% and 30.5% had postmenopausal bleeding (p < .01). No sonographic parameter enabled differentiation of endometrial polyp from cancer. Of patients with endometrial cancer, 72% exhibited signs suggestive of hyperplasia, and endometrial polyps were diagnosed during hysteroscopy. Estrogen receptors (≥ 2 vs ≥ 1; p < .001) and progesterone receptors (≥ 3 vs ≥ 2; p = .07) were greater in endometrial polyps. There was no significant difference in microvessel density (p > .05). CONCLUSIONS: Ultrasonographic parameters and endothelial markers did not enable differentiation of polyps from endometrial neoplasia. Postmenopausal bleeding and endometrial hypervascularization along with vascular atypia at diagnostic hysteroscopy showed a greater association with endometrial cancer.

Teoria imunológica da endometriose: o papel das citocinas / Endometriosis immune theory: the role of citokines

Há várias teorias para explicar a patogênese da endometriose. Recentemente, a hipótese da participação do sistema imunológico na etiopatogenia da endometriose tem contribuído para preencher as lacunas existentes nas demais teorias vigentes. Atualmente, grande parte das pesquisas em endometriose, são fundamentadas na capacidade do peritônio para reagir ao endométrio ectópico por meio de sua destruição e remoção. As principais células envolvidas no desenvolvimento e perpetuação da endometriose são provenientes da linhagem monocítico-macrofágica. Estas agem associadas à produção de várias citocinas, com função imuno-reguladora, ativadora ou supressora. Entre as principais citocinas envolvidas na patogênese da endometriose e que apresentam concentração elevada no soro ou no líquido peritoneal de portadoras da doença, podemos citar: o fator de necrose tumoral, as interleucinas, o fator de crescimento endotelial vascular, as metaloproteases de matriz extracelular, a proteína quimiotáxica dos monócitos, o fator inibidor de migração de macrófagos, o peptídeo epitelial ativador de neutrófilos e a leptina. A utilização in vivo dessas substâncias tem sido estudada na propedêutica laboratorial da endometriose, por meio de sua identificação no soro e no líquido peritoneal de portadoras da doença

Neoplasias malignas iniciando em focos de endometriose após terapia de reposiçäo hormonal (TRH) / Malignant neoplasms in endometriosis foci after hormonal replacement therapy (HRT)

A transformaçäo maligna em focos de endometriose foi documentada há muitos anos por Sampson, 1925. Desde entäo, muitos casos têm sido relatados. A exata incidência da transformaçäo maligna é entretanto, desconhecida. Os ovários e o septo reto vaginal säo os dois principais locais de malignizaçäo. O mais freqüente tipo histológico encontrado nas lesöes ovarianas e extra ovarianas foi o adenocarcinoma endometrióide. Säo descritos casos associados à reposiçäo de estrogênios na menopausa que poderiam induzir a malignizaçäo, semelhante ao que ocorre com o carcinoma de endomêtrio. Frente a estas evidências parece prudente que as histerectomizadas, com antecedentes de endometriose, recebam reposiçäo hormonal combinada para prevenir possível malignizaçäo de focos restantes.
