Metastases are rare in early breast cancer (EBC), and international guidelines recommend against routine systemic staging for asymptomatic patients. However, imaging exams remain widely employed in the clinical practice. The aim of the present study is to evaluate the value of imaging for systemic staging in EBC.
A retrospective analysis of newly-diagnosed breast cancer (BC) patients was performed. Clinical data including BC subtype, stage, presence of symptoms at diagnosis and instrumental procedures performed for staging were recorded.
A total of 753 patients were included, with a median age of 57 years. The majority of the patients underwent at least 1 imaging procedure (91%); had invasive ductal carcinoma (83.5%); histological grade 2 (51.4%); stage II (61.8%); and luminal subtype (67.9%). Among the 685 (91%) patients who underwent any radiologic staging, distant metastases (DMs) were detected in 32 (4.7%). In the univariate analyses, stage IIb and pathological lymph node involvement (pN1) showed a statistically significant association with the presence of DMs, versus only a trend for triple negative and human epidermal growth factor receptor 2 (Her2) positive subtype. In an exploratory analysis performed in this same subgroup, when unfavorable biology (triple negative or Her2 positive) was present, patients had a DM rate of 14.4%, one of the highest reported at this stage of the disease.
Early breast cancer has a low prevalence of DM at the initial evaluation, and systemic staging of asymptomatic, unselected patients is not warranted as a routine practice. However, we have identified subgroups of patients to whom a full staging could be indicated.

To estimate the cytological and colposcopic performances for the diagnosis of cervical neoplasias.
Cross-sectional retrospective study with data from patients’ charts. The participants underwent colposcopy, guided biopsies, and excision when needed. The cytological and colposcopic categorization followed the Bethesda System and the international colposcopic terminologies. The cytology and colposcopy performances were evaluated by sensitivity (SE), specificity (SP), positive predictive value (PPV), and negative predictive value (NPV) analyses with 95% confidence interval (95% CI).
From 1,571 participants, a total of 1,154 (73.4%) were diagnosed with cervical squamous intraepithelial neoplasia grade 2 or worse (CIN 2+), 114 (7.2%) with adenocarcinoma in situ or worse (AIS+), 615 (39.2%) presented atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesion or worse (ASC-H+) cytology, and 934 (59.4%) presented major or suspicious for invasion colposcopic abnormalities. The SE, SP, PPV, and NPV of ASC-H+ for diagnoses of CIN 2+ and AIS+ were, respectively: 44% (95% CI: 41-47) and 72% (95% CI: 67-76), 79% (95% CI: 77-81) and 79% (95% CI: 75-83), 88% (95% CI: 87-90) and 55% (95% CI: 50-60), and 28% (95% CI: 26-31) and 88% (95% CI: 85-91). The SE, SP, PPV, and NPV of major or suspicious for invasion colposcopic abnormalities for diagnoses of CIN 2+ and AIS+were, respectively: 62% (95% CI: 60-65) and 86% (95% CI: 83-89), 59% (95% CI: 57-62) and 59% (95% CI: 55-64), 85% (95% CI: 83-87) and 44% (95% CI: 40-49), and 29% (95% CI: 27-32) and 92% (95% CI: 89-94).
The SE analyses results of ASC-H+ and major or suspicious for invasion colposcopic abnormalities were higher for diagnoses of glandular neoplasias. These results confirm the role of cytology in identifying women at risk who will have their final diagnoses settled by colposcopy and histology.

To study the structure ofmaternalmortality caused by abortion in the Tula region.
The medical records of deceased pregnant women, childbirth, and postpartum from January 01, 2001, to December 31, 2015, were analyzed.
Overall, 204,095 abortion cases were recorded in the Tula region for over 15 years. The frequency of abortion was reduced 4-fold, with 18,200 in 2001 to 4,538 in 2015. The rate of abortions per 1,000 women (age 15-44 years) for 15 years decreased by 40.5%, that is, from 46.53 (2001) to 18.84 (2015), and that of abortions per 100 live births and stillbirths was 29.5%, that is, from 161.7 (2001) to 41.5 (2015). Five women died from abortion complications that began outside of the hospital, which accounted for 0.01% of the total number. In the structure of causes of maternal mortality for 15 years, abortion represented 14.3% of the cases. Lethality mainly occurred in the period from 2001 to 2005 (4 cases). Among thematernal deaths, many women died in rural areas after pregnancy termination at 18 to 20 weeks of gestation (n = 4). In addition, three women died from sepsis and two from bleeding.
The introduction of modern, effective technologies of family planning has reduced maternal mortality due to abortion.

To establish the Pregnancy Sexual Response Inventory (PSRI) scores for each domain before and during pregnancy, and to publish the Brazilian Portuguese version of the PSRI.
Pregnant women were recruited during antenatal care; the PSRI was administered to 244 women prenatally at Faculdade de Medicina de Botucatu, at Universidade do Estado de São Paulo (UNESP, in the Portuguese acronym). The PSRI scores were estimated based on the Kings Health Questionnaire (KHQ) and the Medical Outcomes Study 36-item short form survey (SF-36). The raw scale type was used to standardize the minimal value and amplitude of each domain. For each domain, the score varied from 0 to 100, and the composite score was obtained as the domain average. The composite score before and during pregnancy was determined by the sum of the scores of all specific domains for each divided by the full domain number. The categorization of the scale into quartiles was established when all PSRI-specific and composite scores were combined.
The composite and specific scores for each domain were categorized into quartiles: 0 < 25 as “very bad;” 25 < 50 as “bad;” 50 < 75 as “good” and 75 to 100 as “excellent.” The mean scores were lower during pregnancy than before pregnancy in 8 of the 10 domains. The Brazilian Portuguese PSRI version is presented.
This study allowed the establishment of the PSRI composite and specific scores for each domain, and the categorization of scores into quartiles: very bad, bad, good and excellent. In addition, the Brazilian Portuguese version of the PSRI is presented in full for application in the Brazilian population.

To determine which mode and potency of electrocoagulation, using a modern electrosurgical generator, yields the smallest unobstructed area of the Fallopian tubes.
In an experimental study, tubes from 48 hysterectomies or tubal ligation were evaluated. Tubes were randomly allocated to one of the following groups: group A) 25 W x 5 seconds (n = 17); group B) 30 W x 5 seconds (n = 17); group C) 35 W x 5 seconds (n = 18), group D) 40 W x 5 seconds (n = 20); group E) 40 W x 5 seconds with visual inspection (blanch, swells, collapse) (n = 16); group F) 50 W x 5 seconds (n = 8). Bipolar electrocoagulation was performed in groups A to E, and monopolar electrocoagulation was performed in group F. Coagulation mode was used in all groups. Digital photomicrography of the transversal histological sections of the isthmic segment of the Fallopian tube were taken, and themedian percentage of unobstructed luminal area (mm2) was measured with ImageJ software (ImageJ, National Institutes of Health, Bethesda, MD, USA). The Kruskal-Wallis test or analysis of variance (ANOVA) was used for statistical analysis.
Ninety-six Fallopian tube sections were analyzed. The smallest median occluded area (%; range) of the Fallopian tube was obtained in the group with 40 W with visual inspection (8.3%; 0.9-40%), followed by the groups 25 W (9.1%; 0-35.9%), 40 W (14.2; 0.9-43.2%), 30 W (14.2; 0.9-49.7%), 35 W (15.1; 3-46.4%) and 50 W (38.2; 3.1-51%). No statistically significant difference was found among groups (p = 0.09, Kruskal-Wallis test).
The smallest unobstructed area was obtained with power setting at 40 W with visual inspection using a modern electrosurgical generator. However, no statistically significant difference in the unobstructed area was observed among the groups using these different modes and potencies.

To discuss the implementation and contributions of the External Quality Monitoring in the city of Rio de Janeiro and to analyze the performance of the main providers of cervical cytopathology in this city from September 2013 to March 2017, here referred to as “Alpha laboratory” and “Beta laboratory.”
Observational, cross-sectional, retrospective study using information from the Cervical Cancer Control Information System (SISCOLO, in the Portuguese acronym), municipal coordinationmodule, External QualityMonitoring report. The proportions of false positives, false negatives, unsatisfactory samples and rejected samples were estimated. The agreement among the observers was analyzed through the Kappa index and the reduction of disagreements in the period for each laboratory studied, comparing the results of each cycle.
A total of 19,158 examinations were selected, of which 19,130 (99.85%) were monitored, 16.649 (87, 03%) were reviewed by the External Quality Monitoring Unit, 2,481 (12,97%) were rejected and 441 (2,65%) were considered unsatisfactory. The “Beta laboratory” presented excellent concordance in all cycles; the “Alpha laboratory” had good concordance in the first two cycles (K = 0.76 and 0.79), becoming excellent in the following four cycles. The average Kappa index was 0.85, with median of 0.86. The percentage of diagnostic disagreement was 6.63% of the reviewed exams, of which 5.38% required a change of conduct
External Quality Monitoring is an exercise in diagnostic improvement, and its implementation was fundamental to ensure the reliability of the cytopathological exams in the city of Rio de Janeiro.

The aim of this study was to assess the time trends and pattern of cervical cancer diagnosed in the period from 2001 to 2012 by means of an opportunistic screening program from two developed regions in Brazil.
An observational study analyzing 3,364 cancer records (n = 1,646 from Campinas and n = 1,718 from Curitiba region) available in hospital-based cancer registries was done. An additional 1,836 records of CIN3/AIS from the region of Campinas was analyzed. The statistical analysis assessed the pooled data and the data by region considering the year of diagnosis, age-group, cancer stage, and histologic type. The Cochran-Armitage trend test was applied and p-values < 0.05 were considered significant.
The total annual cervical cancer registered from2001 to 2012 showed a slight drop (273-244), with an age average of 49.5 y, 13 years over the average for CIN3/AIS (36.8 y). A total of 20.6% of the diagnoses (1.6% under 25 y) were done out of the official screening age-range. The biennial rate of diagnoses by age group for the region of Campinas showed an increase trend for the age groups under 25 y (p = 0.007) and 25 to 44 y (p = 0.003). Stage III was the most recorded for both regions, with an annual average of 43%, without any trend modification. There was an increasing trend for stage I diagnoses in the region of Campinas (p = 0.033). The proportion of glandular histologic types registered had an increased trend over time (p = 0.002), higher for the region of Campinas (21.1% versus 12.5% for the region of Curitiba).
The number, pattern and trends of cervical cancer cases registered had mild and slow modifications and reflect the limited effectivity of the opportunistic screening program, even in developed places.
