, , , , , BI-RADS® is a standardization system for breast imaging reports and results created by the American College of Radiology to initially address the lack of uniformity in mammography reporting. The system consists of a lexicon of descriptors, a reporting structure with final categories and recommended management, and a structure for data collection and auditing. It is accepted worldwide by all specialties involved in the care of breast diseases. Its implementation is related to the Mammography Quality Standards Act initiative in the United States (1992) and breast cancer screening. After its initial creation in 1993, four additional editions were published in 1995, 1998, 2003 and 2013. It is adopted in several countries around the world and has been translated into 6 languages. Successful breast cancer screening programs in high-income countries can be attributed in part to the widespread use of BI-RADS®. This success led to the development of similar classification systems for other organs (e.g., lung, liver, thyroid, ovaries, colon). In 1998, the structured report model was adopted in Brazil. This article highlights the pioneering and successful role of BI-RADS®, created by ACR 30 years ago, on the eve of publishing its sixth edition, which has evolved into a comprehensive quality assurance tool for multiple imaging modalities. And, especially, it contextualizes the importance of recognizing how we are using BI-RADS® in Brazil, from its implementation to the present day, with a focus on breast cancer screening.

To study a sample of rheumatoid arthritis (RA) patients for their gynecological/obstetric history and compare them to controls to determine their influences on number of pregnancies, menarche, menopause and reproductive years following RA onset.
This is a cross-sectional study of 122 RA patients and 126 controls. Patients and controls were questioned about age of menarche, age of menopause, number of pregnancies and abortions. Reproductive years were calculated as the difference between age at menopause and age at menarche. For comparison, we used the Mann-Whitney, unpaired t, chi-squared, and Spearman tests. The adopted significance was 5%.
In the RA patients with disease beginning in the postmenopausal years, the period of reproductive years (age at menopause - age of menarche) showed a positive correlation with age at disease onset (rho=0.46; 95% confidence interval [CI]=0.20- 0.55 with p=0.0008). The number of pregnancies was higher in patients with postmenopausal disease onset when compared with those with premenopausal disease onset (median of 3 with interquartile range [IQR]=2-4 versus median of 2 with IQR=1-3; p=0.009), and RA patients had more pregnancies than controls (p=0.0002).
The present study shows that, in our population, the duration of reproductive years and the number of pregnancies are linked to the onset of RA.

PURPOSE: To identify the etiology of nonimmune hydrops fetalis cases in pregnant women diagnosed and referred for prenatal care. METHODS: Retrospective analysis of cases with nonimmune hydrops fetalis that were monitored between March 1992 and December 2011. Diagnosis was confirmed by the presence of fetal subcutaneous edema (≥5 mm) with effusion in at least one serous cavity using obstetric ultrasound, and etiological investigation was conducted with cytogenetic (karyotype), infectious (syphilis, parvovirus B19, toxoplasmosis, rubella, cytomegalovirus, adenovirus and herpes simplex), hematologic and metabolic (inborn errors) analysis and fetal echocardiography. Twin pregnancies were excluded. Statistical analysis was performed using the χ² test for adhesion (software R 2.11.1). RESULTS: We included 116 patients with nonimmune hydrops fetalis; the etiology was elucidated in 91 cases (78.5%), while 25 cases (21.5%) were classified as idiopathic. Most cases had a chromosomal etiology, for a total of 26 cases (22.4%), followed by lymphatic etiology with 15 cases (12.9% with 11 cases of cystic hygroma), and cardiovascular and infectious etiology with 14 cases each (12.1%). In the remaining cases, the etiology was thoracic in 6.9% (eight cases), malformation syndromes in 4.3% (five cases), extrathoracic tumors in 3.4% (four cases), metabolic in 1.7% (two cases), and hematologic, gastrointestinal and genitourinary in 0.9% (one case each). During the postnatal period, 104 cases were followed up until the 40th day of life, and 12 cases had intrauterine fetal death. The survival rate of these 104 newborns was 23.1% (24 survived). CONCLUSION: An attempt should be made to clarify the etiology of hydrops diagnosed during pregnancy since the condition is associated with a wide spectrum of diseases. It is especially important to determine whether a potentially treatable condition is present and to identify disease at risk for recurrence in future pregnancies for adequate pre-conception counseling.
