RESUMEN

Introduction: This study aims to understand (a) how remote workers respond to threats to their identity and (b) the conditions in which each coping response tends to occur more frequently. Methods: To this end, we pursued a grounded theory approach, conducting interviews with 71 individuals who chose to work remotely. Results: Our model and theoretical propositions create insights into how remote workers respond to negative stigma from a range of origins. While some responses lead to restructuring the remote workers' identity (identity restructuring responses), others involve keeping the enactment of such identity (identity-preserving responses) or maintaining a paradoxical relationship between restructuring and preserving the identity (paradoxical identity work responses). We also theorise on the conditions under which each response is more likely to occur. Discussion: We expand the predominant focus on the meso and macro aspects of this type of work to the micro-interactions in which these individuals engage, thus highlighting how identity is made, performed, created, and enacted, within specific boundary conditions. In addition, by reflecting upon remote workers' identity threats in light of the wider macro context. We also explore the conditions under which specific kinds of responses tend to emerge.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

PURPOSE: Compare the lymphatic flow in the arm after breast cancer surgery and axillary lymph node dissection (ALND) versus sentinel lymph node biopsy (SLNB) using lymphos-cintigraphy (LS). PATIENTS AND METHODS: A cross-sectional study with 39 women >18 years who underwent surgical treatment for unilateral breast cancer and manipulation of the axillary lymph node chain through either ALND or SLNB, with subsequent comparison of the lymphatic flow of the arm by LS. The variables analyzed were the area reached by the lymphatic flow in the upper limb and the sites and number of lymph nodes identified in the ALND or SLNB groups visualized in the three phases of LS acquisition (immediate dynamic and static images, delayed scan images). For all analyses, the level of significance was set at 5%. RESULTS: There was a significant difference between the ALND and SLNB groups, with predominant visualization of lymphatic flow and/or lymph nodes in the arm and axilla (P=0.01) and extra-axillary lymph nodes (P<0.01) in the ALND group. There was no significant difference in the total number of lymph nodes identified between the two groups. However, there was a significant difference in the distribution of lymph nodes in these groups. The cubital lymph node was more often visualized in the immediate dynamic images in the ALND group (P=0.004), while the axillary lymph nodes were more often identified in the delayed scan images of the SLNB group (P<0.01). The deltopectoral lymph node was only identified in the ALND group, but with no significant difference. CONCLUSION: The lymphatic flow from the axilla was redirected to alternative extra-axillary routes in the ALND group.

RESUMEN

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.

RESUMEN

Due to widespread use of pelvic and transvaginal ultrasound in routine gynecological evaluation, the incidental finding of adnexal masses has led to discussions about management in asymptomatic patients regarding the risk of ovarian cancer. Transvaginal ultrasonography remains the modality of choice in the evaluation of suspicious characteristics. The combined analysis of ultrasound morphological parameters with Doppler study, serum carcinoma antigen 125 and investigation of a symptom index may improve diagnosis. Surgical approach should be considered whenever there are suspicious images, rapid growth of cysts, changes in the appearance compared to the initial evaluation or when the patient has symptoms. Future studies on genetic and molecular mechanisms may help explain the pathophysiology of ovarian cancer, improving early diagnosis and treatment.

RESUMEN

Summary Due to widespread use of pelvic and transvaginal ultrasound in routine gynecological evaluation, the incidental finding of adnexal masses has led to discussions about management in asymptomatic patients regarding the risk of ovarian cancer. Transvaginal ultrasonography remains the modality of choice in the evaluation of suspicious characteristics. The combined analysis of ultrasound morphological parameters with Doppler study, serum carcinona antigen 125 and investigation of a symptom index may improve diagnosis. Surgical approach should be considered whenever there are suspicious images, rapid growth of cysts, changes in the appearance compared to the initial evaluation or when the patient has symptoms. Future studies on genetic and molecular mechanisms may help explain the pathophysiology of ovarian cancer, improving early diagnosis and treatment.


Resumo Em virtude da ampla utilização da ultrassonografia pélvica e transvaginal na avaliação ginecológica de rotina, o achado incidental de massas anexiais tem ocasionado discussões sobre a conduta em pacientes assintomáticas frente ao risco de desenvolvimento do câncer de ovário. A ultrassonografia transvaginal continua a ser a modalidade de primeira escolha na avaliação de características suspeitas. A análise conjunta de parâmetros morfológicos ultrassonográficos com o estudo Doppler, a pesquisa de CA-125 e a investigação de índice de sintomas pode incrementar as taxas de diagnóstico. Abordagem cirúrgica deve ser considerada sempre que houver alterações em exames de imagem, quando houver crescimento rápido do cisto, mudanças em seu aspecto em relação à avaliação inicial ou quando a paciente apresentar sintomatologia. Uma compreensão melhor de mecanismos genéticos e moleculares pode auxiliar na elucidação da fisiopatologia do câncer ovariano, aprimorando seu diagnóstico e tratamento precoces.

RESUMEN

The study compared ultrasound and ambulatorial hysteroscopy as diagnostic methods detecting endometrial polyps in postmenopause women. 281 women aged 41-82 years who underwent ambulatorial hysteroscopy were analyzed for presence of uterine bleeding and/or altered transvaginal ultrasound (endometrial thickness ≥5 mm). Ultrasonography detected endometrial polyps in 22.8% of patients and endometrial thickening in the other 59.8%. Hysteroscopy diagnosed endometrial polyps in 80.8%. Ultrasonography showed sensitivity of 88.7%, specificity of 25.4%, positive predictive value of 81.7%, negative predictive value of 37.5% and accuracy of 75.4% in diagnosing endometrial polyps. Hysteroscopy showed 96.4% sensitivity, 74.6% specificity, 93.4% positive predictive value, 84.6% negative predictive value and 91.8% accuracy. Hysteroscopy demonstrated more accuracy than ultrasonography, which is not sufficient for accurate diagnosis.

RESUMEN

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 ...

RESUMEN

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.

RESUMEN

Pólipos endometriais são neoformações resultantes de uma hiperplasia focal da camada basal do endométrio associada a um hiperestímulo hormonal. Sua etiologia ainda não está bem estabelecida, não havendo consenso sobre sua história natural, seu real significado como entidade patológica e sua relação com a neoplasia endometrial. Os pólipos endometriais são a principal indicação de histeroscopia cirúrgica, sem que haja, no entanto, um protocolo definido para seu melhor manejo. Uma visão abrangente sobre essa condição pode auxiliar na escolha da conduta mais adequada. (AU)


Endometrial polyps are neoformations that result from focal hyperplasia of the endometrial basal layer associated with hormonal hyperstimulation. Their pathogenesis is still unclear, and there is no consensus on their natural history, actual relevance as pathologic entities, and relationship with endometrial neoplasia. Endometrial polyps are the most frequent indication of surgical hysteroscopy, but their optimal management remains controversial. Therefore, an overview of this condition may help choosing the most adequate treatment strategies.(AU)

RESUMEN

PURPOSE: to describe hysteroscopy findings in infertile patients. METHODS: this was a retrospective series of 953 patients with diagnosis of infertility evaluated by hysteroscopy. A total of 957 patients investigated for infertility were subjected to hysteroscopy, preferentially during the first phase of the menstrual cycle. When necessary, directed biopsies (under direct visualization during the exam) or guided biopsies were obtained using a Novak curette after defining the site to be biopsied during the hysteroscopic examination. Outcome frequencies were determined as percentages, and the χ2 test was used for the correlations. The statistical software EpiInfo 2000 (CDC) was used for data analysis. RESULTS: a normal uterine cavity was detected in 436 cases (45.8%). This was the most frequent diagnosis for women with primary infertility and for women with one or no abortion (p<0.05). Abnormal findings were obtained in 517 of 953 cases (54.2%), including intrauterine synechiae in 185 patients (19.4%), endometrial polyps in 115 (12.1%), endocervical polyps in 66 (6.0%), submucosal myomas in 47 (4.9%), endometrial hyperplasia in 39 (4.1%), adenomyosis in five (0.5%), endometritis (with histopathological confirmation) in four (0.4%), endometrial bone metaplasia in two (0.4%), and cancer of the endometrium in one case (0.1%). Morphological and functional changes of the uterus were detected in 5.6% of the cases, including uterine malformations in 32 (3.4%) and isthmus-cervical incompetence in 21 (2.2%). CONCLUSIONS: intrauterine synechiae were the most frequent abnormal findings in patients evaluated for infertility. Patients with a history of abortion and infertility should be submitted to hysteroscopy in order to rule out intrauterine synechiae as a possible cause of infertility.

RESUMEN

OBJETIVO: descrever os achados da histeroscopia em pacientes com infertilidade. MÉTODOS: série retrospectiva de 953 pacientes com diagnóstico de infertilidade avaliadas por histeroscopia. As 957 pacientes em pesquisa de infertilidade foram submetidas à histeroscopia, preferencialmente na primeira fase do ciclo menstrual. Quando necessário, foram realizadas as biópsias, dirigida (sob visão direta durante o exame) ou orientada, utilizando uma cureta de Novak após definir o local a ser biopsiado durante o exame histeroscópico. Foram utilizadas porcentagens para determinação da frequência dos desfechos e teste de χ2 para correlações. O programa estatístico EpiInfo 2000 (CDC) foi utilizado para análise dos dados. RESULTADOS: cavidade uterina normal foi encontrada em 436 casos (45,8 por cento). Esse foi o diagnóstico mais frequente em mulheres com infertilidade primária e naquelas com nenhum ou um aborto (p<0,05). Achados anormais foram diagnosticados em 517 de 953 casos (54,2 por cento) e incluíram sinéquias intrauterinas em 185 pacientes (19,4 por cento), pólipo endometrial em 115 (12,1 por cento), pólipos endocervicais em 66 (6,0 por cento), miomas submucosos em 47 (4,9 por cento), hiperplasia endometrial em 39 (4,1 por cento), adenomiose em cinco (0,5 por cento), endometrite (com confirmação histopatológica) em quatro (0,4 por cento), metaplasia óssea endometrial em dois (0,4 por cento) e câncer do endométrio em um caso (0,1 por cento). Alterações morfológicas e funcionais do útero foram detectadas em 5,6 por cento dos casos, incluindo malformações uterinas em 32 (3,4 por cento) e incompetência istmo-cervical em 21 (2,2 por cento). CONCLUSÕES: sinéquias intrauterinas foram os achados anormais mais frequentes em pacientes avaliadas para infertilidade. Pacientes com histórico de aborto e infertilidade devem ser submetidas à histeroscopia para descartar sinéquias intrauterinas como uma possível causa de infertilidade.


PURPOSE: to describe hysteroscopy findings in infertile patients. METHODS: this was a retrospective series of 953 patients with diagnosis of infertility evaluated by hysteroscopy. A total of 957 patients investigated for infertility were subjected to hysteroscopy, preferentially during the first phase of the menstrual cycle. When necessary, directed biopsies (under direct visualization during the exam) or guided biopsies were obtained using a Novak curette after defining the site to be biopsied during the hysteroscopic examination. Outcome frequencies were determined as percentages, and the χ2 test was used for the correlations. The statistical software EpiInfo 2000 (CDC) was used for data analysis. RESULTS: a normal uterine cavity was detected in 436 cases (45.8 percent). This was the most frequent diagnosis for women with primary infertility and for women with one or no abortion (p<0.05). Abnormal findings were obtained in 517 of 953 cases (54.2 percent), including intrauterine synechiae in 185 patients (19.4 percent), endometrial polyps in 115 (12.1 percent), endocervical polyps in 66 (6.0 percent), submucosal myomas in 47 (4.9 percent), endometrial hyperplasia in 39 (4.1 percent), adenomyosis in five (0.5 percent), endometritis (with histopathological confirmation) in four (0.4 percent), endometrial bone metaplasia in two (0.4 percent), and cancer of the endometrium in one case (0.1 percent). Morphological and functional changes of the uterus were detected in 5.6 percent of the cases, including uterine malformations in 32 (3.4 percent) and isthmus-cervical incompetence in 21 (2.2 percent). CONCLUSIONS: intrauterine synechiae were the most frequent abnormal findings in patients evaluated for infertility. Patients with a history of abortion and infertility should be submitted to hysteroscopy in order to rule out intrauterine synechiae as a possible cause of infertility.

RESUMEN

The aim of this study was to confirm the effectiveness of early physiotherapeutic stimulation for lymphatic flow progression in patients with breast cancer undergoing axillary dissection. This was a randomized experimental study on 22 patients who underwent lymphoscintigraphy in their arms on two different occasions, firstly without stimulation and secondly after randomization into two groups: without physiotherapeutic stimulation (WOPS; n=10) and with physiotherapeutic stimulation (WPS; n=12). The lymphoscintigraphy scan was performed with (99m)Tc-phytate administered into the second interdigital space of the hand, ipsilaterally to the dissected axilla, in three phases: dynamic, static, and delayed whole body imaging. Physiotherapeutic stimulation was carried out using Földi's technique. In both groups, images from the two examinations of each patient were compared. Flow progression was considered positive when, on the second examination, the radiopharmaceutical reached areas more distant from the injection site. Statistical analysis was used to evaluate frequencies, percentages and central trend measurements, and non-parametric tests were conducted. Descriptive analysis showed that the WPS and WOPS groups were similar in terms of mean age, weight, height, body mass index and number of lymph nodes removed. There were statistically significant associations between physiotherapeutic stimulation and radiopharmaceutical progression at all three phases of the study (p<0.0001). Early physiotherapeutic stimulation in breast cancer patients undergoing radical axillary dissection is effective, and can therefore be indicated as a preventive measure against lymphedema.

RESUMEN

OBJECTIVE: To describe the prevalence of hysteroscopic findings and histologic diagnoses in patients with abnormal uterine bleeding (AUB). DESIGN: Retrospective series of consecutive patients. SETTING: Tertiary care university hospital and private office. PATIENT(S): Four thousand fifty-four hysteroscopies with biopsy in patients with AUB evaluated between June 1993 and December 2004. INTERVENTION(S): Hysteroscopies were performed using 2.9-mm or 4-mm telescopes with CO(2) or saline as the distension media. Biopsies were done with a 5-mm grasper or with a Novak's curette. MAIN OUTCOME MEASURE(S): Prevalence of hysteroscopic findings and histologic analysis of biopsies. RESULT(S): Endometrial polyp was the most frequent hysteroscopic finding, accounting for 1,374 (33.9%) cases. Normal uterine cavity and cervical canal were found in 814 (20.1%) patients. Submucous fibroids were diagnosed in 302 (7.5%) women. Normal endometrium was the most frequent histologic diagnosis, accounting for 1,888 (46.6%) cases. Endometrial polyp was found in 1,115 (27.5%) patients. Endometrial hyperplasia was diagnosed in 613 (15.1%) and endometrial cancer in 105 (2.6%) women. CONCLUSION(S): Endometrial polyps are the most frequent hysteroscopic findings in patients with AUB, whereas normal endometrium is the most frequent histologic diagnosis.

RESUMEN

OBJECTIVE: To investigate the efficacy of soy isoflavone on climacteric symptoms in postmenopausal women. DESIGN: In this double-blind, randomized, placebo-controlled study, a total of 80 women (mean age = 55.1 years), who reported 5 or more hot flush episodes per day, were randomized to receive either 250 mg of standardized soy extract (Glycine max AT) a total of 100mg/day of isoflavone (n = 40) or placebo (n = 40). Exclusion criteria included: contra-indication for hormone therapy (HT), chronic gastrointestinal diseases, and users of HT within the preceding 6-months. For 10-months, climacteric symptoms were evaluated using a score card and the menopausal Kupperman index. Compliance and safety were also assessed. At baseline and the end of the study, lipid and hormonal profiles, as well as vaginal, mammographic and ultrasonographic parameters were measured. The t-test, Wilcoxon test and ANOVA were used in the statistical analysis. RESULTS: At baseline, the mean number of hot flushes was 9.6 +/- 3.9 per day in the isoflavone group and 10.1+/-4.9 in the placebo group (p>0.05). After 10 months, there was a significant reduction in frequency of hot flushes among isoflavone users when compared to those on placebo (3.1 +/- 2.3 and 5.9 +/- 4.3, respectively) (p<0.001). Kupperman index mean values showed a significant reduction in both groups. However, soy isoflavone was significantly superior to placebo, in reducing hot flush severity (69.9% and 33.7%, respectively) (p<0.001). Endometrial thickness, mammography, vaginal cytology, lipids and hormonal profile did not change in both groups. No serious adverse event related to isoflavone treatment was reported. CONCLUSIONS: The soy isoflavone extract exerted favorable effects on vasomotor symptoms and good compliance, providing a safe and effective alternative therapeutic for postmenopausal women.

RESUMEN

OBJETIVO: avaliar a densidade mamográfica (DM) de mulheres na pós-menopausa submetidas ao tratamento com raloxifeno. MÉTODOS: em estudo aberto prospectivo, não randomizado, avaliaram-se 80 mulheres (média de idade=61,1 anos). Quarenta pacientes receberam 60 mg/dia de raloxifeno e 40 mulheres compuseram o grupo não tratado (controle), pareadas pela idade e tempo de menopausa. O grupo tratado foi composto por pacientes com osteoporose da coluna lombar. Foram excluídas aquelas com história de cirurgia mamária e usuárias de terapia hormonal (TH) até seis meses prévios. A DM foi avaliada de forma qualitativa (subjetiva) e quantitativa (objetiva) em dois momentos: inicial e após seis meses de seguimento. As 320 mamografias (crânio-caudal e oblíqua) foram interpretadas qualitativamente pela classificação do Breast Imaging Reporting and Data System (BI-RADS) e quantitativamente pela digitalização computadorizada da imagem. Para análise estatística empregaram-se os testes t, Wilcoxon Mann-Whitney, correlação de Spearman e teste de concordância de kappa. RESULTADOS: na comparação estatística inicial, os grupos foram homogêneos para todas as variáveis analisadas (idade, tempo de menopausa, paridade, amamentação, TH prévia e índice de massa corpórea). Na DM inicial, pelos métodos qualitativo e quantitativo, houve correlação negativa com a idade, em ambos os grupos (p<0,05). Para as demais variáveis analisadas, não houve correlação significativa. Após seis meses não se encontrou alteração na DM em 38 usuárias de raloxifeno e 38 controles pela análise qualitativa, enquanto que pela análise quantitativa, a imagem manteve-se inalterada em 30 usuárias de raloxifeno e em 27 controles (p>0,05). Observou-se fraco valor de concordância (kappa=0,25) entre a classificação de BI-RADS e a digitalização da imagem. CONCLUSÕES: mulheres na pós-menopausa com osteoporose, submetidas ao tratamento com raloxifeno por seis meses, não apresentaram alterações no padrão de DM.


PURPOSE: to evaluate changes in mammographic breast density in postmenopausal women using raloxifene. METHODS: in this clinical trial, 80 women (mean age=61.1 years) were studied prospectively. Forty patients received 60 mg/day raloxifene, and 40 women comprised the non-treated group (control), paired by age and time of menopause. The treated group was composed of patients with osteoporosis of the lumbar spine. Those with history of breast surgery and users of hormone therapy up to six months prior to the study were excluded. The breast density was assessed qualitatively (subjective) and quantitatively (objective) in two moments, initial and final, after a 6-month follow-up. The 320 mammograms (craniocaudal and oblique) were interpreted qualitatively by the Breast Imaging Reporting and Data System (BI-RADS) classification and quantitatively by digital scanning and computer-assisted segmentation. For statistical analysis t-test, Wilcoxon Mann-Whitney, Spearman correlation and the kappa index were used. RESULTS: on the initial statistical comparison, the groups were considered homogenous for the variables: analyzed age, time of menopause, parity, breast feeding, previous hormonal therapy and body mass index. Baseline breast density, by qualitative and quantitative methods, correlated negatively with the age in both groups (p<0.05). Concerning the other variables, there was no correlation. After six months, no alteration was observed in the mammographic breast density in 38 women of raloxifene group and 38 of the control group, by qualitative method. However, by quantitative method, no alteration was observed in 30 women of the raloxifene group and 27 controls (p>0.05). It was observed a weak agreement rate (kappa=0.25) between the BI-RADS classification and digital scanning/computer-assisted segmentation. CONCLUSIONS: in post-menopausal women with osteoporosis, submitted to raloxifene treatment for six months, no alterations were observed...
