Excellent aesthetic results were more frequent in the OP group according to BCCT.core software analysis and specialists. In addition, some clinical conditions and tumor locations in the breast can be considered risky factors for poor aesthetic outcomes in lumpectomy.

Background: This retrospective study aims to determine: 1) the sensitivity of preoperative mammography (Mx) and ultrasound (US), and re-reviewed Mx to detect multifocal multicentric breast carcinoma (MMBC), defined by pathology on surgical specimens, and 2) to analyze the characteristics of both detected and undetected foci on Mx and US.

In this retrospective report, the use of omalizumab in Brazilian children with STRA significantly improved disease control, decreased hospitalizations, and allowed suspension of continuous oral corticosteroids.

Objective: To describe the clinical characteristics, lung function, radiological findings, and the inflammatory cell profile in induced sputum in children and adolescents with severe therapy-resistant asthma (STRA) treated at a referral center in southern Brazil. Methods: We retrospectively analyzed children and adolescents (3-18 years of age) with uncontrolled STRA treated with high-dose inhaled corticosteroids and long-acting ß2 agonists. We prospectively collected data on disease control, lung function, skin test reactivity to allergens, the inflammatory cell profile in induced sputum, chest CT findings, and esophageal pH monitoring results. Results: We analyzed 21 patients (mean age, 9.2 ± 2.98 years). Of those, 18 (86%) were atopic. Most had uncontrolled asthma and near-normal baseline lung function. In 4 and 7, induced sputum was found to be eosinophilic and neutrophilic, respectively; the inflammatory cell profile in induced sputum having changed in 67% of those in whom induced sputum analysis was repeated. Of the 8 patients receiving treatment with omalizumab (an anti-IgE antibody), 7 (87.5%) showed significant improvement in quality of life, as well as significant reductions in the numbers of exacerbations and hospitalizations. Conclusions: Children with STRA present with near-normal lung function and a variable airway inflammatory pattern during clinical follow-up, showing a significant clinical response to omalizumab. In children, STRA differs from that seen in adults, further studies being required in order to gain a better understanding of the disease mechanisms.

Objective: To determine the role of urine cytology for ‘decoy cells’ as a screening tool for polyomavirus type BK (BKV) infection in renal transplant recipients. Study Design: This was a prospective cohort study of patients undergoing renal transplantation between 2006 and 2010. Results: A total of 442 patients underwent urine cytology for decoy cells, 27.8% underwent 1 examination only and 72.2% more than one. Of the 1,713 examinations reviewed, 426 (24.9%) were positive and 785 (45.8%) were negative for ‘decoy’ cells, 380 (22.2%) showed degenerated tubular cells and 122 (7.1%) were unsatisfactory for analysis. Urine cytology was found to have a specificity of 68.5%, a sensitivity of 84.6%, a positive predictive value of 21.2%, a negative predictive value of 97.8% and an overall accuracy of 69.9%. The incidence of polyomavirus nephropathy among the patients investigated was 11.8%. Of the 442 patients, 32 (7.2%) had graft loss, which was attributed to BKV nephropathy in 2 (6.2% of the 32). Conclusions: Urine cytology is an effective screening method for monitoring renal transplant patients, with high sensitivity and a high negative predictive value, and can therefore be used routinely in the follow-up of renal transplant patients.

Immediate breast reconstruction with implants and contralateral symmetrization had a positive impact on the quality of life and showed satisfactory outcomes when evaluated by subjective and objective methods.

Objective: This study was performed to evaluate the potential influence of cytological differences between pleural effusions on the survival of women with metastatic breast cancer during 30 months of follow-up. Study Design: A hospital-based cohort study was performed. Pleural fluid cytology slides from patients with breast cancer were examined. Cases were grouped according to the pattern of tumor cells (spheroid and isolated), in order to access their prognostic value. Results: The study comprised 87 patients. An isolated cell pattern was associated with higher mortality 30 months after the pleural effusion when compared to a spheroid pattern (p = 0.038). Patients with an isolated cell pattern showed higher risk of dying than patients with spheroid formations. The relative risk after adjustment of intervening variables was 5.336 (95% CI 1.054-27.020). The presence of a triple-negative immunohistochemical pattern significantly increased the risk of mortality before 30 months. Conclusion: Pleural effusion with isolated malignant cells is associated with worse prognosis after 30 months of follow-up.
