ABSTRACT
(1) Background: Breast abscess (BA) is a condition leading in the majority of cases to breastfeeding interruption. Abscesses are commonly treated with antibiotics, needle aspiration or incision and drainage (I&D), but there is still no consensus on the optimal treatment. Since there are no well-defined clinical guidelines for abscess management, we conducted a retrospective, observational study with the aim of assessing ultrasound (US)-guided management of BA without surgery, regardless of the BA size. The secondary objective was the microbiologic characterization and, in particular, the S. aureus methicillin resistance identification. (2) Methods: our population included 64 breastfeeding mothers with diagnosis of BA. For every patient, data about maternal, perinatal and breastfeeding features were collected. All patients underwent office US scans and 40 out of 64 required a more detailed breast diagnostic ultrasound performed by a radiologist. In all cases, samples of milk or abscess material were microbiologically tested. All patients received oral antibiotic treatment. We performed needle aspiration, when feasible, even on abscesses greater than 5 cm. (3) Results: most of the women developed BA during the first 100 days (68.8% during the first 60 days) after delivery and 13 needed hospitalization. Four abscesses were bilateral and 16 had a US major diameter greater than 5 cm. All patients were treated with antibiotic therapy according to our clinical protocol and 71.9% (46/64) underwent fine needle aspiration. None of them required I&D. The average duration of breastfeeding was 5 months (IR 2; 9.5) and 40.6% of women with BA continued to breastfeed for more than 6 months. Only 21 mothers interrupted breastfeeding before 3 months. (4) Conclusions: our observational data suggest, regardless of the size and the clinical features of the BA, a conservative approach with antibiotic therapy targeted at the Methicillin-Resistant Staphilococcus aureus (MRSA) identified and needle aspiration, if feasible. In our experience, treatment with needle aspiration is a cost- effective method. Unlike drainage, it is an outpatient procedure, easily repeatable, with no cosmetic damage. In addition, it has lower risk of recurrences since, differently from surgical incision, it does not cause interruption of the ducts. Moreover, needle aspiration is less painful, does not require the separation of the mother-child dyad and allows for a quicker, if not immediate, return to breastfeeding.

BACKGROUND: Breastfeeding women are at risk of developing mastitis during the lactation period. Staphylococcus aureus has emerged as the community-acquired pathogen responsible for virulence (methicillin resistance and Panton-Valentine leukocidin toxin producing). RESEARCH AIM: The aim was to compare the microorganisms responsible for mastitis and breast abscesses during breastfeeding. METHODS: This observational study was conducted with a sample of women (N = 60) admitted to our hospital between 2016 and 2018. Participants affected by mastitis and breast abscess were studied and cared for by a multidisciplinary working group. A diagnostic breast ultrasound identified the pathology. RESULTS: Twenty-six participants (43.3%) were affected by mastitis and 34 (56.7%) by breast abscess. The most common microorganism identified was Staphylococcus aureus (S. aureus; mastitis, n = 13; abscesses, n = 24). Methicillin resistance was identified in 21 (44.7%) S. aureus strains: 17 (80.9%) cases of abscess and four (19.1%) cases of mastitis. The median number of months of breastfeeding was smaller in the methicillin-resistant S. aureus (MRSA) cases (median = 3, range = 1-20 months) than in the methicillin-sensitive S. aureus (MSSA) cases (median = 6.5, range = 3-21 months). The Panton-Valentine leukocidin toxin gene was detected in 12 (25.5%) cases (MRSA, n = 8, 66.7%; MSSA, n = 4, 33.3%). Hospitalization was required more frequently in MRSA (n = 8, 38%; five Panton-Valentine leukocidin positive) than in MSSA cases (n = 5, 19%; one Panton-Valentine leukocidin positive). Four women out of the eight MRSA cases (50%) that were Panton-Valentine leukocidin positive stopped breastfeeding during mammary pathologies, three (37.5%) participants continued breastfeeding until the follow-up recall, and one case was lost at follow-up. CONCLUSION: Clinical severity was probably complicated by the presence of the Panton-Valentine leukocidin toxin, which required hospitalization more frequently.

Obtaining a tailored breast resection is challenging in microcalcifications detected on screening mammography, and an accurate localization is required. The aim of this study was to compare the efficacy of radio-guided localization (ROLL) versus ultrasound localization of a titanium clip with collagen (TCC) in terms of clear margins, re-intervention rates, excess of resected breast tissue, and operative times in pure malignant microcalcifications detected on screening mammography. Two hundred and twenty-one consecutive patients with malignant microcalcifications detected on screening mammography from a tertiary breast unit were reviewed: 177 patients were localized by TCC and 44 patients by stereotactic ROLL. A propensity score-matched analysis was performed, followed by a logistic regression model, to avoid selection bias. Adequacy of resection was expressed as the calculated resection ratio considering lesion size. No differences were found in clear margins with ROLL versus TCC (77.3% vs 81.8%, adjusted OR 2, P = 0.27). Re-operation rates were similar, being 11.3% with ROLL and 7.4% with TCC (P = 0.627). Mean resection volume was 46.2 cm3 with ROLL versus 54.2 cm3 with TCC (P = 0.222). Adjusted mean calculated resection ratio was 1.8 with ROLL and 2.1 with TCC (P = 0.38). Surgery time was longer with TCC compared to ROLL (69.6 vs 52.7 minutes, P < 0.0001). ROLL and TCC are equally effective to excise malignant microcalcifications with clear margins, providing similar re-intervention rates and resection volumes.

BACKGROUND: The equipment to detect indocyanine green (ICG) fluorescence for sentinel lymph node (SLN) biopsy in breast cancer is not widely accessible nor optimal. The fluorescence appears as a poorly defined white shine on a black background, and dimmed lighting is required. The aim of this study was to assess the feasibility, accuracy and healthcare costs of a novel approach for SLN biopsy by a video-assisted ICG-guided technique. METHODS: The technique for detecting SLN was radioisotope (RI) in 194 cases, video-assisted ICG-guided in 70 cases and a combined method in 71 cases. In the video-assisted ICG group, a full HD laparoscopic system equipped with xenon lamps was used for a laser-free detection of ICG within a colored and magnified high-resolution image. RESULTS: Detection of ICG fluorescence using a laparoscope with a near-infrared filter provided a highly defined and colored image during SLN biopsy. SLN was identified in 100% of patients in all groups. Multiple SLNs were identified in 0.5% of RI patients, in 12.9% of ICG patients and in 14.1% of ICG + RI patients (p < 0.0001). In ICG + RI group, 95.1% of lymph nodes were radioactive and 92.7% were fluorescent. Operative times and healthcare costs were equivalent between groups. CONCLUSIONS: Video-assisted ICG-guided technique is a feasible and surgeon-friendly method for SLN biopsy, with equivalent efficacy compared to RI, providing an accurate staging of the axilla.

Sentinel lymph node biopsy for ductal carcinoma in situ (DCIS) of the breast is not standard of care. However, nodal involvement for DCIS patients is reported. Aim of our study was to identify preoperative features predictive of nodal involvement in DCIS patients. We have retrospectively reviewed 175 patients with a preoperative diagnosis of DCIS following a vacuum-assisted breast biopsy, and undergoing surgery with sentinel node biopsy. Variables distribution was compared between patients upstaged to invasive cancer at final pathology and patients with a confirmed DCIS, and between positive vs negative sentinel node patients. Univariate and multivariate analyses were performed for risk of a positive node. Lymph node biopsy was positive in 13 (7.4%) patients, with 8 (61.5%) macrometastases and 5 (38.5%) micrometastases. In these patients, Breast Imaging Reporting and Data System (BI-RADS) index >4 (OR 4.69, 95% CI 1.282-17.224, P = .02), lesion extension ≥20 mm (OR 4.25, 95% CI 1.255-14.447, P = .02), multifocal disease (OR 4.12, 95% CI 0.987-17.174, P = .05), comedo type (OR 3.54, 95% CI 1.044-11.969, P = .04), and upstaging (OR 4.56, 95% CI 1.080-19.249, P = .04) were all predictive of nodal involvement, although upstaging could not be predicted preoperatively. By multivariate analysis, the only independent factor predictive for positive sentinel node was multifocal disease (OR 5.14, 95% CI 1.015-26.066, P < .05). A preoperative diagnosis of DCIS, also including advanced biopsy systems such as vacuum-assisted breast biopsy, may be not always sufficient to exclude patients from sentinel node biopsy. DCIS patients with associated BI-RADS >4, lesion extension ≥20 mm, comedo type, and above all multifocal disease should be considered for axillary evaluation.

AIM: This study aimed to evaluate the benefits of Arnica montana on post-operative blood loss and seroma production in women undergoing unilateral total mastectomy by administering Arnica Montana 1000 Korsakovian dilution (1000 K). MATERIALS AND METHODS: From 2012 to 2014, 53 women were randomly assigned to A. montana or placebo and were followed up for 5 days. The main end point was the reduction in blood and serum volumes collected in drainages. Secondary end points were duration of drainage, a self-evaluation of pain, and the presence of bruising or hematomas. RESULTS: The per-protocol analysis revealed a lower mean volume of blood and serum collected in drainages with A. montana (-94.40 ml; 95% confidence interval [CI]: 22.48-211.28; P = 0.11). A regression model including treatment, volume collected in the drainage on the day of surgery, and patient weight showed a statistically significant difference in favor of A. montana (-106.28 ml; 95% CI: 9.45-203.11; P = 0.03). Volumes collected on the day of surgery and the following days were significantly lower with A. montana at days 2 (P = 0.033) and 3 (P = 0.0223). Secondary end points have not revealed significant differences. CONCLUSIONS: A. montana 1000 K could reduce post-operative blood and seroma collection in women undergoing unilateral total mastectomy. Larger studies are needed with different dilutions of A. montana to further validate these data.
ABSTRACT
BACKGROUND: Achieving clear margins with adequate resection volumes is one of the principal goals of breast-conserving surgery. The aim of our study was to compare preoperative localization using 2 different clips, radiopaque or sonographically visible, to reach this goal. METHODS: We reviewed 209 consecutive nonpalpable breast cancers that were treated with lumpectomy: 59 with radiopaque and 150 with sonographically visible clip positioned during biopsy procedure. In the former case, preoperative localization was performed with mammography and in the latter by ultrasonography. RESULTS: Clear margins were achieved in 80.4% of patients: 57.6% in the first and 89.3% in the second group (P < .0001; odds ratio, 7.6; 95% confidence interval, 3.4 to 17.2). By using sonographically visible clips, the re-excision rate has decreased from 42.4% to 10.7%, (P < .0001), and resections resulted smaller with average calculated resection ratio of 3.54 vs. 5.08 (P = .03). CONCLUSIONS: Preoperative localization using a sonographically visible clip allows a more tailored breast-conserving surgery and reduces the re-excision rate.

BACKGROUND: Paget's disease (PD) of the breast is a relatively rare condition (incidence 1-3%) among primary breast cancers [6]. It presents with suggestive symptoms like erythema, nipple bleeding and ulceration. PATIENT AND METHODS: A 76-year-old woman was followed up for cancer of the left breast that had been operated 10 years before. During her annual check, a lesion suggestive of PD was detected. Mammography and ultrasound were performed, without evidence of a new breast lesion. In consideration of a possible underestimation of the real extent of the disease, we performed magnetic resonance imaging (MRI). RESULTS: MRI showed an irregularly shaped tissue infiltrating the external side of the right breast. The pathologically bright signal involved the nipple and deformed the areolar skin. The characteristics of the increased signal were typical of a hypervascular invasive pattern and for tumoral neoangiogenesis. We performed a mastectomy with sentinel lymph node (SLN) biopsy, with evidence of a DIN 3 carcinoma associated with PD of the nipple at the final pathology report. CONCLUSION: The MRI was instrumental for the assessment of the existence and extent of malignant disease in a patient with PD but without a palpable lesion detectable with negative ultrasound and mammography.
ABSTRACT
We describe a case of a 37-year-old woman with a left axillary mass. Often, the initial differential diagnosis of an axillary mass is not easy to make. We performed fine-needle aspiration of the axillary mass that revealed the presence of numerous epithelial neoplastic cells. A bilateral digital mammography, chest and abdomen computed tomography scan, and a magnetic resonance imaging scan (MRI) of the axillary region were performed. In our case, the MRI was able to exclude the presence of neoplastic tissue in the breast; moreover, it confirmed the presence of metastatic lymph nodes and recognized a second type of nodular lesion in the axilla, showing on the MRI a radiologic pattern similar to breast tissue.

BACKGROUND: Bowel ultrasound has been proven to be a useful tool in the management of Crohn's disease, particularly in the assessment of intra-abdominal complications, most of which require surgery. MATERIALS AND METHODS: The National Library of Medicine has been searched for articles on the use of bowel ultrasound in Crohn's disease focusing on aspects of interest to the surgeon. RESULTS AND CONCLUSIONS: Several studies have demonstrated that bowel ultrasound may be useful to reduce the risk of unnecessary laparotomy in patients presenting acute abdomen with suspected chronic inflammatory bowel disease. Bowel ultrasound has been proven to be of value in the follow-up of Crohn's disease patients since allowing early diagnosis of intra-abdominal complications and, therefore, optimising the diagnostic and surgical approach. At followup, bowel ultrasound may accurately diagnose early postoperative complications and long-term disease recurrence. In patients submitted to conservative surgery, ultrasonography reveals changes in diseased bowel walls that may be predictive of recurrence of the disease, and hence determinant in the choice of medical treatment.

BACKGROUND: Bowel-sparing techniques have been proposed to avoid extended or repeated resections in patients with Crohn'rsquo;s disease (CD), but without precise indications, prospective evaluation, and with a technically limited repertoire. STUDY DESIGN: A prospective longitudinal study of new nonconventional strictureplasties (NCSP) in order to evaluate the safety, type and site of recurrence, and longterm clinical and surgical efficacy. RESULTS: Between January 1993 and December 2002, 102 among 305 consecutive patients underwent at least one NCSP for complicated CD. Patients were treated following precise indications and then included in a prospective database with scheduled followup. Factors claimed to influence postoperative and longterm outcomes and type and site of recurrence were analyzed. We performed 48 ileoileal side-to-side isoperistaltic strictureplasty (SP), 41 widening ileocolic SP, 32 ileocolic side-to-side isoperistaltic SP, associated with Heineke-Mikulicz SP (in 80 procedures) or with minimal bowel resections or both (in 47 procedures). Postoperative mortality was nil; complication rate was 5.7%. Ten years clinical and surgical recurrence rates were 43% and 27%, respectively. Recurrence rate on an NCSP site was 0.8%. No specific factor was identified as related to postoperative or longterm outcomes. CONCLUSIONS: Perioperative and longterm results of NCSP are comparable to or even better than both conservative and resective surgery as reported in the literature, with a low recurrence rate on the NCSP site. Considering the unpredictability of the clinical course of CD and the lifetime need for surgical procedures, NCSP, together with minimal resection and classic SP repertoire, should be considered first-line treatment in complicated CD.
