Background : DiaRem score consists in preoperative model for predicting remission of type 2 diabetes mellitus in obese patients who underwent gastric bypass. Aim : To evaluate the applicability of DiaRem comparing the scores obtained preoperatively with remission of T2DM after surgery. Method : Preoperative parameters such as age, use of insulin, oral hypoglycemic agents and glycated hemoglobin, were retrospectively evaluated in diabetic patients undergoing gastric bypass during the period between July 2012 to July 2013. Through these data the DiaRem score were applied. The results of fasting blood glucose and glycated hemoglobin were requested prospectively. Results : Were selected 70 patients; the remission of T2DM after surgery was found in 42 (60%) and no remission in 28 (40%). Checking the final score, it was observed that: from 0 to 2 points, 94.1% of patients remitted completely; between 3 and 7 had remission in 68.9%, of which 42.8% complete; from 8 to 12, 57.1% achieved complete remission; between 13 to 17, 87.5% did not achieve remission and was not seen this complete remission group; between 18 to 22, 88.9% were not remitted. Conclusion : The DiaRem score showed appropriate tool to assess remission of T2DM in obese patients who will undergo gastric bypass.
The authors report on neurological damage caused by the use of sublaminar segmental fixation in the correction of vertebral deformities. Three groups were reviewed: 600 patients instrumented with Harrington rods and segmental wiring, 50 patients treated with the Hartshill system and 100 patients instrumented with Luque bars. All of the patients were operated on using sublaminar wiring fixation. We report two transitory neurological complications among the 600 patients with Harrington rod instrumentation and segmental wiring, two permanent neurological deficits among the 50 cases treated with the Hartshill system and none among the 100 patients instrumented using Luque bars. The purpose of this study is to analyse the causes of these neurological complications, which occurred late in all four of the cases described.

Introduction: The Breast Imaging Reporting and Data System (BI-RADS®) was developed in 1993 by the American College of Radiology to standardize reports based on imaging findings, classifying them into six categories. Its fourth edition proposed the subdivision of category 4 into three subcategories according to malignancy suspicion. Category 4A shows likelihood of malignancy between 2% and 10%, and diagnosis by biopsy is recommended. Frequent histological findings in the literature for 4A lesions include fibrocystic breast changes, fibroadenoma, columnar cell lesions with atypia, stromal sclerosis, inflammatory disorders, and proliferative epithelial lesions. Objectives: To show the most relevant radiological and histological findings for the BI-RADS® 4A subcategory, corroborating its likelihood ratio of malignancy. Methods: This is a cross-sectional study based on the review of medical records of patients submitted to the anatomopathological study of BI-RADS 4A lesions in public and private health services from Curitiba, Paraná, Southern Brazil, between March and September 2019. The findings were subsequently correlated with histopathological results. Results: A total of 727 core needle breast biopsies were performed – 78.6% guided by ultrasound and 21.4% by stereotaxy. Approximately 35.8% of ultrasound-guided procedures (group X) and 55.4% of stereotaxic biopsies (group Y) were classified as BI-RADS 4A. Among the main imaging findings in group X, solid nodules, solid cystic lesions, and solid heterogeneous areas stood out. Group Y presented clusters of heterogeneous, punctate, amorphous microcalcifications, and findings that did not fit the BI-RADS classification. Benign changes predominated among the histopathological findings in both groups. The malignancy rate according to guidelines of the European classification for anatomopathological results of breast lesions4 remained around 2% in group X and 8.7% in group Y. Conclusions: Based on the results obtained, we concluded that the malignancy rates of biopsies from patients classified as BI-RADS 4A were within the acceptable values established by the literature. However, they varied considerably according to the biopsy method chosen, presenting higher values in patients submitted to stereotaxy.
