PURPOSE: to verify the amount of CD68+ cells in chorionic villosities in placentae from gestations submitted or not to labor. METHODS: transversal study with healthy near-term pregnant women, among whose placentae, 31 have been examined by immunohistochemical technique. Twenty placentae were obtained after vaginal delivery (VAGG) and eleven after elective cesarean sections (CESG). Slides were prepared with chorionic villosities samples and labeled with anti-CD68 antibody, specific for macrophages. Labeled and nonlabeled cells were counted inside the villosities. Non-parametric statistical tests were used for the analysis. RESULTS: among the 6,424 cells counted in the villosities' stroma from the 31 placentae, 1,135 cells (17.6%) were stained by the CD68+. The mean of cells labeled by the anti-CD68 was 22±18 for the VAGG group and 20±16 for the CESG, in each placentary sample. CONCLUSIONS: there were no significant differences in the percentage of macrophages (CD68+) in association with labor.

The hydatiform mole is a relatively rare pregnancy complication, but with potential to evolve to forms which need systemic treatment and can be a threat to life. There are two histopathological and clinical entities under the name of hydatiform mole: the partial and the complete mole. The differences between the two forms are important due to risk of evolution to persistent forms, which is higher for the complete moles. The diagnosis, treatment and follow-up of hydatiform mole have been under important changes in the last years. The number of asymptomatic patients has increased, due to the use of ultrasonography at the onset of pregnancy. The use of medication that induces uterine contractions must be avoided, and vacuum aspiration should be used. Soon after emptying the mole, a hormonal contraceptive method should be prescribed. Follow-up should be based on weekly serial dosages of chorionic gonadotropin. It is important that the method employed detects all the forms of chorionic gonadotropins (intact molecule, with hyper glycol, free β subunit, and central fragment β subunit).

PURPOSE: the objective of this study was to evaluate the clinical, pathological and molecular characteristics in very young women and postmenopausal women with breast cancer. METHODS: we selected 106 cases of breast cancer of very young women (<35 years) and 130 cases of postmenopausal women. We evaluated clinical characteristics of patients (age at diagnosis, ethnic group, family history of breast cancer, staging, presence of distant metastases, overall and disease-free survival), pathological characteristics of tumors (tumor size, histological type and grade, axillary lymph nodes status) and expression of molecular markers (hormone receptors, HER2, p53, p63, cytokeratins 5 and 14, and EGFR), using immunohistochemistry and tissue microarray. RESULTS: when comparing clinicopathologic variables between the age groups, younger women demonstrated greater frequency of nulliparity (p=0.03), larger tumors (p<0.000), higher stage disease (p=0.01), lymph node positivity (p=0.001), and higher grade tumors (p=0.004). Most of the young patients received chemotherapy (90.8%) and radiotherapy (85.2%) and less tamoxifen therapy (31.5%) comparing with postmenopausal women. Lower estrogen receptor positivity 49.1% (p=0.01) and higher HER2 overexpression 28.7% (p=0.03) were observed in young women. In 32 young patients (29.6%) and in 20% of the posmenopausal women, the breast carcinomas were of the triple-negative phenotype (p=0.034). In 16 young women (50%) and in 10 postmenopausal women (7.7%), the tumors expressed positivity for cytokeratin 5 and/or 14, basal phenotype (p=0.064). Systemic metastases were detected in 55.3% of the young women and in 39.2% of the postmenopausal women. Breast cancer overall survival and disease-free survival in five years were, respectively, 63 and 39% for young women and 75 and 67% for postmenopausal women. CONCLUSIONS: breast cancer arising in very young women showed negative clinicobiological characteristics and more aggressive tumors.

PURPOSE: to evaluate the quality of life and sexuality features of women with breast cancer, according to the type of surgery they underwent and their sociodemographic characteristics. METHODS: transversal study with 110 women treated for breast cancer, for at least one year in the Centro de Atenção Integral à Saúde da Mulher of UNICAMP. The quality of life was assessed by the WHOQOL-bref questionnaire, and the issues on sexuality, by a specific questionnaire in which Cronbach's Alpha coefficient was used to validate the concordance of responses (alpha=0.72) and the technique of factor analysis, with the criterion of self value and variance maximum rotation, resulting in two components: intrinsic or intimacy ( how the woman sees herself sexually) and extrinsic or attractiveness (how the woman believes the others see her sexually). Sociodemographic variables have been assessed according to the WHO questionnaire, and the sexuality components, through the Kruskal-Wallis followed by the Mann-Whitney's test and Spearman correlation test. RESULTS: age, schooling, type of surgery and lapse of time from the surgery did not influence the quality of life concerning physical, environmental, and psychological aspects, as well as the social relationships. Women with a stable marital relationship got higher scores in the psychological area (p=0.04) and in the area of social relationships (p=0.02). Higher socioeconomic level influenced the quality of life concerning physical appearance (p=0.01) and environment (p=0.002). Regarding the sexuality, age had influence in the extrinsic component (p=0.0158). Women with a stable marital relationship had higher scores of quality of life in both components of sexuality. Higher schooling influenced in a positive way the intrinsic factor. Women submitted to quadrantectomy or mastectomy with immediate breast reconstruction showed higher scores relating to attractiveness in comparison to mastectomized women without reconstruction. CONCLUSIONS: better socioeconomic level and better schooling, stable marital relationship and surgery with breast conservation are linked to better rates of quality of life, including sexuality.

PURPOSE: to asses the prevalence and clinical characteristics of couples with history of recurrent spontaneous abortion and chromosome abnormality, attended at the present service. METHODS: all the couples referred to our service due to history of recurrent spontaneous abortion, from January 1975 to June 2008, were evaluated. Only the ones whose chromosome karyotype analysis by GTG bands has been successfully made were included in the study. Clinical data on their age, as well as on the number of abortions, stillbirth, multiple malformations, livebirth per couple, and the result of the karyotype exam were collected. Fisher's exact test (p<0.05) has been used to compare the incidence of chromosome alterations found in our study, with data in the literature. RESULTS: there were 108 couples in the sample. Their ages varied from 21 to 58 years old among the men (average of 31.4 years old), and from 19 to 43 among the women (average of 29.9 years old). In ten couples, one of the mates (9.3%) presented chromosome alterations, which corresponded respectively to three cases (30%) of reciprocal translocation [two of t(5;6) and one of t(2;13)], two (20%) of Robertsonian translocation [two of der(13;14) and one of der(13;15)], five(50%) of mosaicism (mos) [two cases of mos 45,X/46,XX, one of mos 46,XX/47,XXX, one of mos 46,XY/47,XXY and one of mos 46,XY/47,XYY] and one (10%) of chromosome inversion [inv(10)]. In one of the couples, the female presented two concomitant alterations: t(2;13) and der(13;14). Chromosome abnormalities were found in 5% of the couples with a history of two abortions, in 10.3% with three abortions, and in 14.3% with four or more abortions. CONCLUSIONS: the incidence of chromosome abnormalities seen in our study (9.3%) was similar to most of the studies carried out in the last 20 years, varying from 4.8 to 10.8%. Nevertheless the high percentage of patients with mosaicism in our sample, has called our attention. It is believed that this fact may be associated to the high number of metaphases ordinarily analyzed in the present service.
