Abstract	Background: Excision is routinely recommended for atypical ductal hyperplasia (ADH) found on core biopsy given cancer upstage rates of near 20%. Identifying a cohort at low-risk for upstage may avoid low-value surgery. Objectives were to elucidate factors predictive of upstage in ADH, specifically near-complete core sampling, to potentially define a group at low upstage risk. Patients and methods: This retrospective, cross-sectional, multi-institutional study from 2015 to 2019 of 221 ADH lesions in 216 patients who underwent excision or active observation (≥ 12 months imaging surveillance, mean follow-up 32.6 months) evaluated clinical, radiologic, pathologic, and procedural factors for association with upstage. Radiologists prospectively examined imaging for lesional size and sampling proportion. Results: Upstage occurred in 37 (16.7%) lesions, 25 (67.6%) to ductal carcinoma in situ (DCIS) and 12 (32.4%) to invasive cancer. Factors independently predictive of upstage were lesion size ≥ 10 mm (OR 5.47, 95% CI 2.03-14.77, p < 0.001), pathologic suspicion for DCIS (OR 12.29, 95% CI 3.24-46.56, p < 0.001), and calcification distribution pattern (OR 8.08, 95% CI 2.04-32.00, p = 0.003, "regional"; OR 19.28, 95% CI 3.47-106.97, p < 0.001, "linear"). Near-complete sampling was not correlated with upstage (p = 0.64). All three significant predictors were absent in 65 (29.4%) cases, with a 1.5% upstage rate. Conclusions: The upstage rate among 221 ADH lesions was 16.7%, highest in lesions ≥ 10 mm, with pathologic suspicion of DCIS, and linear/regional calcifications on mammography. Conversely, 30% of the cohort exhibited all low-risk factors, with an upstage rate < 2%, suggesting that active surveillance may be permissible in lieu of surgery.

Abstract	Diagnostic mammography is routinely ordered, along with targeted breast ultrasound, to evaluate breast symptoms in women 30-39 years of age. However, in this age group, mammography is often limited by breast density and the probability of detecting an occult malignancy is low. We sought to evaluate whether diagnostic mammography detected any new incidental malignancies in women aged 30-39 years presenting with focal breast symptoms. This retrospective study included women 30-39 years of age who had a diagnostic mammogram performed for focal breast symptoms at a single institution from 2002 to 2017. Descriptive analyses were performed to determine the rate of incidental mammographic findings outside of the region of the presenting symptom that 1) led to additional imaging and/or biopsies and 2) were found to be malignant. During the 16-year study period, 1770 evaluations were performed, of which 249 (14.1%) were found to have an additional incidental mammographic abnormality. Further diagnostic imaging was required in 211 (11.3%), core biopsy in 67 (3.8%), and excisional biopsy in 8 (0.5%). None of the mammographically detected incidental findings resulted in a new diagnosis of breast cancer. In the evaluation of focal benign breast symptoms in women 30-39 years of age, diagnostic mammography did not detect any new incidental malignancies outside of the area of interest, but instead led to additional unavailing imaging and biopsy procedures. The mammography component of the diagnostic evaluation of younger average-risk women may potentially be omitted if the presenting symptom is determined to be benign with ultrasound alone.

Abstract	Abstract: Breast augmentation and reconstruction utilizing implants are among the most common plastic surgery procedures performed in the United States. A small proportion of these implants are removed each year. We report 2 cases where routine pathologic evaluation of capsulectomy specimens revealed squamous cell carcinoma associated with the breast implant capsule and discuss the possible pathogenesis of this unusual entity. Both patients had long-standing implants (>10 years) and presented with acute unilateral breast erythema and swelling. Intraoperatively, the capsules for both cases appeared thickened and calcified, containing extensive granulomatosis and keratinaceous debris invading into the chest wall. Extensive workup failed to find an occult primary. One patient died from a malignant pleural effusion secondary to tumor invasion during chemotherapy, and the second patient obtained stabilization of the mass after 5 weeks of chemotherapy but subsequently declined further surgical intervention. A thorough literature review was performed, and 5 similar reports were identified, involving 6 patients. All patients presented with similar clinical presentations as ours and had poor outcomes. The mean reporting age at diagnosis was 60 years, and the average time from initial implant to diagnosis was 25 years. Due to the small numbers of squamous cell carcinomas associated with breast implant capsules, the true association between the 2 is unknown. It is postulated that chronic inflammation/irritation from the breast implant and epithelialization of the capsule play a significant role in the disease process. This may represent a new entity of "chronic inflammatory capsular malignancies." Increased awareness of this entity may allow for earlier suspicion, diagnosis, and management.

Abstract	Lymphoepithelioma-like carcinoma of the breast is a rare malignancy, with fewer than 20 cases documented in the literature. Given the paucity of reported cases, there is limited information available to guide the diagnosis and management of patients with this tumor. We present a case of a 39-year-old woman with a palpable right breast mass that was initially diagnosed by core needle biopsy as infiltrating carcinoma with prominent lymphoplasmacytic stroma. Subsequent neoadjuvant chemotherapy with docetaxel, doxorubicin, and cyclophosphamide resulted in a marked decrease in the size of the mass. After wide local surgical excision, pathology revealed a lymphoepithelioma-like carcinoma of the breast. Given the excellent treatment response, our experience may help clinicians determine future therapeutic strategies for this rare breast tumor.

Abstract	Objective: The purpose of this article is to present neuroimaging findings in tuberous sclerosis complex, including recently developed imaging techniques that have demonstrated clinical benefit to this patient population. Conclusion: Neuroimaging advances have improved the diagnosis of tuberous sclerosis complex and the treatment of children with this condition. Superimposition of functional information from PET onto MRI allows accurate and noninvasive identification of epileptogenic tubers, improving surgical cure rates. Magnetic source imaging can also be used to localize epileptiform activity arising from tubers.

Abstract	Background: There is currently no clear consensus recommendation for the use of short-interval follow-up mammography after a benign-concordant breast biopsy (BCBB), and practice patterns vary widely. The objectives of this study were to evaluate whether a short-interval follow-up mammogram provided clinical utility after stereotactic BCBB and to examine the costs associated with this surveillance strategy. Methods: A retrospective review of women who underwent a stereotactic breast biopsy yielding benign-concordant results between January 2005 and October 2014 was performed to evaluate findings on subsequent imaging, to calculate compliance with recommended short-interval imaging, and to examine whether subsequent imaging revealed an abnormality at the site of the initial stereotactic BCBB. A cost analysis was performed utilizing Medicare reimbursement rates to calculate projected and actual costs of short-interval follow-up imaging after stereotactic BCBB. Results: Of the 470 stereotactic BCBB performed, a short-interval mammogram was completed in 207 (44.0%), 9 (4.3%) of which had suspicious mammographic findings at the initial biopsy site, and 6 subsequently underwent biopsy, with none resulting in malignant or high-risk pathology. The cost of short-interval mammographic follow-up (n = 207) was calculated at $28,541.16. Conclusions: This study provides evidence that 6-month follow-up mammography has low clinical utility and unnecessarily increases costs after stereotactic BCBB. A safe and more cost-effective strategy may be resumption of routine mammography at 12 months post-biopsy.

Abstract	One of the most important subjects of hydraulic engineering is the reliable estimation of the transverse distribution in the rectangular channel of bed and wall shear stresses. This study makes use of the Tsallis entropy, genetic programming (GP) and adaptive neuro-fuzzy inference system (ANFIS) methods to assess the shear stress distribution (SSD) in the rectangular channel. To evaluate the results of the Tsallis entropy, GP and ANFIS models, laboratory observations were used in which shear stress was measured using an optimized Preston tube. This is then used to measure the SSD in various aspect ratios in the rectangular channel. To investigate the shear stress percentage, 10 data series with a total of 112 different data were used. The results of the sensitivity analysis show that the most influential parameter for the SSD in a smooth rectangular channel is the dimensionless parameter B/H, Where the transverse coordinate is B, and the flow depth is H. With the parameters (b/B), (B/H) for the bed and (z/H), (B/H) for the wall as inputs, the modeling of the GP was better than the other one. Based on the analysis, it can be concluded that the use of GP and ANFIS algorithms is more effective in estimating shear stress in smooth rectangular channels than the Tsallis entropy-based equations.
