[Extensive transfixing skin necrosis after breast biopsy under local anesthesia: About four cases]. / Nécrose cutanée étendue transfixiante après biopsie mammaire sous anesthésie locale : rapport de quatre cas.

INTRODUCTION: Local anesthetics with adrenaline are widely used in routine practice and have long proven their benefits and safety. The rare complications due to their use mainly concern immuno-allergic and vascular mechanisms. DESCRIPTION: In this article, we present four similar cases of early transfixing skin necrosis occurring after radioguided breast biopsy under local anesthesia using epinephrine local anesthetics in the context of a diagnostic approach to breast cancer. DISCUSSION: Although the literature is comforting about the use of local anesthetics, even on the extremities, severe skin complications continue to be reported sporadically. The analysis and understanding of these phenomena would allow, in the long run, to avoid them and to reduce their importance. CONCLUSION: The occurrence of skin necrosis after breast biopsy under radiographic control is rare and seems to be related to the local anesthetic procedure. Although similar cases have been reported in the literature, it does not seem possible today to conclude on the exact physiopathology of these complications. A better knowledge of the pathophysiology of these complications would help to avoid their occurrence in the future.

LC/MS-based untargeted lipidomics reveals lipid signatures of nonpuerperal mastitis.

BACKGROUND: Nonpuerperal mastitis (NPM) is a disease that presents with redness, swelling, heat, and pain during nonlactation and can often be confused with breast cancer. The etiology of NPM remains elusive; however, emerging clinical evidence suggests a potential involvement of lipid metabolism. METHOD: Liquid chromatography‒mass spectrometry (LC/MS)-based untargeted lipidomics analysis combined with multivariate statistics was performed to investigate the NPM lipid change in breast tissue. Twenty patients with NPM and 10 controls were enrolled in this study. RESULTS: The results revealed significant differences in lipidomics profiles, and a total of 16 subclasses with 14,012 different lipids were identified in positive and negative ion modes. Among these lipids, triglycerides (TGs), phosphatidylethanolamines (PEs) and cardiolipins (CLs) were the top three lipid components between the NPM and control groups. Subsequently, a total of 35 lipids were subjected to screening as potential biomarkers, and the chosen lipid biomarkers exhibited enhanced discriminatory capability between the two groups. Furthermore, pathway analysis elucidated that the aforementioned alterations in lipids were primarily associated with the arachidonic acid metabolic pathway. The correlation between distinct lipid populations and clinical phenotypes was assessed through weighted gene coexpression network analysis (WGCNA). CONCLUSIONS: This study demonstrates that untargeted lipidomics assays conducted on breast tissue samples from patients with NPM exhibit noteworthy alterations in lipidomes. The findings of this study highlight the substantial involvement of arachidonic acid metabolism in lipid metabolism within the context of NPM. Consequently, this study offers valuable insights that can contribute to a more comprehensive comprehension of NPM in subsequent investigations.

Clinical Implications and Management of Non-BIA-ALCL Breast Implant Capsular Pathology.

SUMMARY: The breast implant capsule is a dynamic structure that forms following the implantation of a device. Although normally benign, increased awareness of breast implant-associated anaplastic large-cell lymphoma (BIA-ALCL) highlights that disease may arise from the capsule. BIA-ALCL presents as a late seroma or mass but explains few of the late seromas found in breast implant patients. To date, many of these seromas lack a clear cause and are often described as "idiopathic." Several benign and malignant breast implant capsular diseases can cause a late seroma or mass, including breast implant-associated squamous cell carcinoma. Similar to early reports of BIA-ALCL, these conditions are rare and largely limited to case reports or series. The purpose of this special topic is to present a narrative review highlighting capsular abnormalities that contribute to the formation of late seroma or mass in an attempt to broaden the differential diagnosis and help plastic surgeons identify the cause. Specifically, we review the presentation and management of BIA-ALCL, synovial metaplasia, capsular epithelialization, late hematoma, double capsule, breast cancer, squamous cell carcinoma, mesenchymal tumor, and B-cell lymphoma. Although rare, plastic surgeons should consider these capsular conditions as causes of late seromas and masses. Usually, these conditions may be diagnosed by following the National Comprehensive Cancer Network screening guidelines for BIA-ALCL. Thorough evaluation and workup of late seromas and masses may lead to improved characterization of these rare breast implant capsular conditions and improve our understanding of their pathophysiology and management.

The formation mechanism of the bilayer capsular contracture after an augmentation mammoplasty with a rough-surface prosthesis and its prevention and treatment.

BACKGROUND: The present study aimed to explore the formation mechanism of the bilayer capsular contracture after augmentation mammoplasty with a rough-surface prosthesis and its prevention and treatment. METHODS: The nursing process, clinical signs, intraoperative findings, and pathological data after an augmentation mammoplasty with rough-surface prosthesis were observed and collected, the formation mechanism of the bilayer capsular contracture was analyzed, and the prevention and treatment were also discussed. RESULTS: A total of 18 patients were included into the present study, among which 15 patients underwent capsule relaxation plus secondary augmentation mammoplasty and three patients encountered a single-layer capsular contracture after the operation; the recurrence rate was 16%. All patients were followed up for 1-13 years without a presentation of recurrence. CONCLUSIONS: The formation of the bilayer capsular contracture after augmentation mammoplasty is correlated with the formation of the inner capsule, inadequate separation of cavities, foreign body reaction, and an improper massage of the breasts, and the effective preventive measures include removing new cavities, resecting the capsular contracture capsule, stopping bleeding, replanting a rough-surface or smooth prosthesis, and correcting breast massaging.

Effects of the Kampo medicine Yokukansan for perioperative anxiety and postoperative pain in women undergoing breast surgery: A randomized, controlled trial.

Yokukansan (YKS) is a traditional Japanese herbal (Kampo) medicine prescribed for anxiety. In this randomized controlled trial, we compared the subjective assessment of anxiety using questionnaires and its objective assessment using salivary alpha-amylase concentrations in YKS and control (CNT) groups of women undergoing breast surgery. The trial was registered at the University Hospital Medical Information Network Clinical Trials Registry (registration number: UMIN000028998), and the investigators were blinded to drug administration. One hundred patients who underwent breast cancer surgery were allocated to either the YKS or the CNT group. Finally, 35 and 42 patients in the YKS and CNT groups were analyzed, respectively. The YKS group received two 2.5 g doses of the medication before sleeping on the night before surgery and 2 h before inducing anesthesia, while the CNT group did not receive medication preoperatively. Patients answered two questionnaires, the Hospital Anxiety and Depression Scale and the State-Trait Anxiety Inventory, pre-and postoperatively as subjective anxiety assessments. As an objective anxiety indicator, salivary alpha-amylase levels were measured the day before, directly before, and the day after surgery (T3). In the YKS group, salivary alpha-amylase scores directly before operation were significantly lower than those on the day before surgery and at one day postoperatively (F [2,150] = 3.76, p = 0.03). Moreover, the Hospital Anxiety and Depression Scale-Anxiety and State-Trait Anxiety Inventory-Trait scores were significantly more improved postoperatively in the YKS group than in the CNT group (difference in Hospital Anxiety and Depression Scale-Anxiety: YKS, mean -2.77, 95% confidence interval [-1.48 --4.06], p <0.001, and CNT, -1.43 [-0.25--2.61], p = 0.011; and difference in State-Trait Anxiety Inventory: YKS group, -4.23 [-6.95--1.51], p = 0.0004; and CNT group, 0.12 [-2.36-2.60], p = 0.92). No side effects were associated with YKS. YKS may reduce perioperative anxiety in patients undergoing surface surgery.

A retrospective study on 221 patients with granulomatous lobular mastitis treated by a combination of traditional Chinese medicine and western medicine.

OBJECTIVE: This study aims to investigate the clinical efficacy and safety of integrative Chinese and Western medicine in the treatment of granulomatous lobular mastitis. METHODS: In the present study, the clinical data of patients with granulomatous lobular mastitis in our hospital were retrospectively analyzed. According to the treatment regimens, these patients were divided into two groups: observation group (n=92) and control group (n=129). Patients in the observation group were treated with traditional Chinese medicine in combination with the surgical treatment of Western medicine, while the patents in the control group received surgical treatment alone. The main observation indexes included clinical cure rate, mass size, prolactin level and aesthetic evaluation results of the breasts. RESULTS: The results revealed that there was no significant correlation between the observation group and control group, in terms of age, prolactin level, and marriage and childbearing history (P>0.05). Furthermore, the recurrence rate was lower in the observation group, when compared to the control group, and the difference was statistically significant (P<0.05). The aesthetic evaluation was higher in the observation group than in the control group, and the difference was statistically significant (P<0.05). However, the difference in the transverse diameter and long diameter of the tumor and clinical cure rate was not statistically significant (P>0.05) between the observation group and control group. CONCLUSION: Compared with the simple surgical treatment of Western medicine, the combination of traditional Chinese medicine and Western medicine in the treatment of granulomatous lobular mastitis can significantly reduce the recurrence rate, and improve the symmetry and beauty of bilateral breasts, which is worthy of clinical application. KEY WORDS: Granulomatous lobular mastitis, Integrated Chinese and western medicine treatment, Unclog lacteal, Prolactin, Aesthetic evaluation of milk preservation.

Safety and Effectiveness of Silicone Gel-Filled Breast Implants in Primary Augmentation Patients.

BACKGROUND: Results from the MemoryGel Breast Implants Core Clinical Study suggest these devices are safe and effective at 10 years after implantation. Although clinical trials are essential for measuring the safety and effectiveness of a device, real-world evidence can supplement clinical trials by providing information on outcomes observed in diverse clinical settings for a more heterogeneous population, without fixed treatment patterns, and without continuous patient monitoring, such that follow-up is more representative of normal clinical practice. OBJECTIVES: The aim of this study was to measure real-world outcomes, including safety and effectiveness, in patients who underwent primary breast augmentation with smooth MemoryGel implants. METHODS: This was a case series looking at patients, age 22 years and older, who underwent primary breast augmentation at a single site between December 2006 and December 2016 and who had a minimum of 2 years of follow-up. Descriptive statistics were used to summarize baseline characteristics and outcomes. Kaplan-Meier models were used to estimate safety outcomes for capsular contracture (Baker grade III/IV), infection, and rupture. RESULTS: A total of 50/777 (6.4%) patients reported a complication, with an average time to complication of 3.9 years (range, 19 days-11.8 years) postprocedure. Kaplan-Meier estimates of the 10-year cumulative incidence of capsular contracture (Baker grade III/IV), infection, and rupture were 4.7%, 0.1%, and 1.6%, respectively. CONCLUSIONS: Analyses of a large population from a single site provide further support for the long-term safety and effectiveness of MemoryGel breast implants in a primary augmentation cohort.

Angiotensin-Converting Enzyme Inhibitor Reduces Radiation-Induced Periprosthetic Capsular Fibrosis.

BACKGROUND: The capsular contracture is one of the main complications after radiotherapy in patients with implant-based reconstruction. The aim of this study is to evaluate the efficacy of ramipril for the prevention of radiation-induced fibrosis around the silicone implant. MATERIALS AND METHODS: Thirty Wistar rats in 5 groups were used. Group 1: implant; group 2: implant + radiation; group 3: ramipril + implant; group 4: ramipril + implant + radiation; group 5: sham. Ramipril treatment was started 5 d before surgery and continued for 12 wk after surgery. A mini silicone implant was placed in the back of the rats. A single fraction of 21.5 Gy radiation was applied. Tissues were examined histologically and immunohistochemically (TGF-ß1, MMP-2, and TIMP-2 expression). The alteration of plasma TGF-ß1 levels was examined before and after the experiment. RESULTS: After applying implant or implant + radiation, capsular thickness, percentage of fibrotic area, tissue and plasma TGF-ß1 levels significantly increased, and MMP-2/TIMP-2 ratio significantly decreased compared with the sham group. In ramipril-treated groups, the decrease in capsular thickness, fibrosis, TGF-ß1 positivity, and an increase in MMP-2/TIMP-2 ratio were found significant. In the ramipril + implant + radiation group, the alteration values of TGF-ß1 dramatically decreased. CONCLUSIONS: Our results show that ramipril reduces radiation-induced fibrosis and contracture. The results of our study may be important for the design of the clinical trials required to investigate the effective and safe doses of ramipril, which is an inexpensive and easily tolerated drug, on humans.

CDX2-positive breast cancer presented with axillary lymph node metastases: A case report.

BACKGROUND: The caudal type homeobox 2 transcription factor (CDX2) is a specific and sensitive marker for intestinal carcinoma, but usually not expressed in breast cancer. In CDX2-positive metastatic cancer of occult primary, the origin is highly suspicious of an enteric carcinoma. CASE PRESENTATION: A 50-year-old woman complained of enlarged lymph nodes (LNs) in the right axilla. Mammography and ultrasonography scans showed no abnormal findings in her breasts. Core needle biopsy (CNB) revealed metastatic adenocarcinoma. Immunohistochemical staining was positive for CDX2 intensely. The primary tumor was suspicious of intestinal adenocarcinoma. A dynamic contrast-enhanced magnetic resonance imaging scan revealed an accentuated lesion which was detected using a second-look ultrasound, and diagnosed invasive ductal carcinoma by CNB. A partial mastectomy of the right breast with level I and II axillary LN dissection was performed. A few cells of primary cancer were expressed CDX2 and estrogen receptor. The final pathological diagnosis was T1bN3aM0 stage IIIC. The fluorescent double staining showed that CDX2 simultaneously expressed on the Ki67 positive cells of metastatic tumors. The adjuvant treatment included chemotherapy and radiation, followed by tamoxifen administration. The patient survived without any recurrences over the following 36 months. CONCLUSIONS: We report a rare case of CDX2-positive metastatic breast cancer in the axillary LNs. As some literatures reported vitamin D pathways induced cancer cell apoptosis and inhibition, these metastatic cells of our case might play the effort of autoregulation of inhibiting progression.

CYP27A1 expression is associated with risk of late lethal estrogen receptor-positive breast cancer in postmenopausal patients.

BACKGROUND: 27-Hydroxycholesterol (27HC) stimulates estrogen receptor-positive (ER+) breast cancer (BC) progression. Inhibiting the sterol 27-hydroxylase (CYP27A1) abrogates these growth-promoting effects of 27HC in mice. However, the significance of CYP27A1 expression on BC biology and prognosis is unclear. METHODS: Intratumoral CYP27A1 expression in invasive BC was measured by immunohistochemistry in two Swedish population-based cohorts (n = 645 and n = 813, respectively). Cox proportional hazards models were used to evaluate the association between CYP27A1 expression and prognosis. RESULTS: CYP27A1 was highly expressed in less than 1/3 of the tumors. High CYP27A1 expression was more frequent among high-grade tumors lacking hormone receptor expression and with larger tumor sizes. Over a median of 12.2 years follow-up in cohort 1, high CYP27A1 expression was associated with impaired survival, specifically after 5 years from diagnosis among all patients [overall survival (OS), HRadjusted = 1.93, 95%CI = 1.26-2.97, P = 0.003; breast cancer-specific survival (BCSS), HRadjusted = 2.33, 95%CI = 1.28-4.23, P = 0.006] and among patients ≥ 55 years presenting with ER+ tumors [OS, HRadjusted = 1.99, 95%CI = 1.24-3.21, P = 0.004; BCSS, HRadjusted = 2.78, 95%CI = 1.41-5.51, P = 0.003]. Among all patients in cohort 2 (median follow-up of 7.0 years), CYP27A1 expression was significantly associated with shorter OS and RFS in univariable analyses across the full follow-up period. However after adjusting for tumor characteristics and treatments, the association with survival after 5 years from diagnosis was non-significant among all patients [OS, HRadjusted = 1.08, 95%CI = 0.05-2.35, P = 0.83 and RFS, HRadjusted = 1.22, 95%CI = 0.68-2.18, P = 0.50] as well as among patients ≥ 55 years presenting with ER+ tumors [OS, HRadjusted = 0.46 95% CI = 0.11-1.98, P = 0.30 and RFS, HRadjusted = 0.97 95% CI = 0.44-2.10, P = 0.93]. CONCLUSION: CYP27A1 demonstrated great potentials as a biomarker of aggressive tumor biology and late lethal disease in postmenopausal patients with ER+ BC. Future studies should investigate if the benefits of prolonged endocrine therapy and cholesterol-lowering medication in BC are modified by CYP27A1 expression.

What is the role of locoregional anesthesia in breast surgery? A systematic literature review focused on pain intensity, opioid consumption, adverse events, and patient satisfaction.

BACKGROUND: Breast surgery in the United States is common. Pain affects up to 50% of women undergoing breast surgery and can interfere with postoperative outcomes. General anesthesia is the conventional, most frequently used anaesthetic technique. Various locoregional anesthetic techniques are also used for breast surgeries. A systematic review of the use of locoregional anesthesia for postoperative pain in breast surgery is needed to clarify its role in pain management. OBJECTIVES: To systematically review literature to establish the efficacy and the safety of locoregional anesthesia used in the treatment of pain after breast surgery. METHODS: Embase, MEDLINE, Google Scholar and Cochrane Central Trials Register were systematically searched in Mars 2020 for studies examining locoregional anesthesia for management of pain in adults after breast surgery. The methodological quality of the studies and their results were appraised using the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) checklist and specific measurement properties criteria, respectively. RESULTS: Nineteen studies evaluating locoregional anesthesia were included: 1058 patients underwent lumpectomy/mastectomy, 142 breast augmentation and 79 breast reduction. Locoregional anesthesia provides effective anesthesia and analgesia in the perioperative setting, however no statistically significant difference emerged if compared to other techniques. For mastectomy only, the use of locoregional techniques reduces pain in the first hour after the end of the surgery if compared to other procedures (p = 0.02). Other potentially beneficial effects of locoregional anesthesia include decreased need for opioids, decreased postoperative nausea and vomiting, fewer complications and increased patient satisfaction. All this improves postoperative recovery and shortens hospitalization stay. In none of these cases, locoregional anesthesia was statistically superior to other techniques. CONCLUSION: The results of our review showed no differences between locoregional anesthesia and other techniques in the management of breast surgery. Locoregional techniques are superior in reducing pain in the first hour after mastectomy.

"Making Peace with Our Bodies": A Qualitative Analysis of Breast Cancer Survivors' Experiences with Qigong Mind-Body Exercise.

Objectives: Breast cancer treatment leaves breast cancer survivors (BCS) with an array of lasting side effects, including persistent postsurgical pain (PPSP). In this study, we explored the perceptions of BCS with PPSP as they learned Qigong mind-body exercise (QMBE), a multimodal practice rooted in Traditional Chinese Medicine. Methods: Participants included 18 female BCS treated for stage 0-III breast cancer and experiencing PPSP. Participants were taught QMBE over 12 weeks. Semi-structured interviews were conducted before and after the intervention. Results: BCS disclosed a disconnect between mind and body that emerged during treatment. They perceived QMBE as moving meditation, which enabled them to reconnect mind and body, lessen their pain, and make peace with their bodies. Conclusion: These women's experiences both inform the promise of integrating QMBE and related mind-body exercise into PPSP clinical practice guidelines and suggest new areas of research regarding the role of multimodal interventions for holistic healing in BCS.

Chemotherapy-related cognitive impairment in patients with breast cancer based on MRS and DTI analysis.

The purpose of this study is to investigate chemotherapy-related cognitive impairment (CRCI) in breast cancer patients, analyze absolute concentration and structural changes of metabolites in different brain regions by multimodal neuroimaging technology, and explore correlation between them. Breast cancer patients with chemotherapy treatment group (Ctx+, N = 24) and control group without treatment (Ctx-, N = 20) underwent neuropsychological tests, multivoxel magnetic resonance spectroscopy (MRS), and diffusion tensor imaging (DTI) before and after chemotherapy. Regions of interest (ROls) in magnetic resonance scan include bilateral posterior cingulate gyrus (PCG), bilateral dorsal thalamus (DT), bilateral lenticular nucleus (LN), bilateral posterior horn of the lateral ventricle paratrigonal white matter (PWM). In MRS, absolute concentrations of N-acetylaspartate (NAA), myo-inositol (MI), choline-containing compounds (Cho), total creatine (tCr), glutamine + glutamate (Glx) were quantified using LC Model and SAGE software. In DTI, we used fractional anisotropy (FA) and mean diffusivity (MD) to reflect white matter integrity. In Ctx+ patients, scores of functional assessment of cancer treatment cognition test (FACT-Cog), perceived cognitive impairments (PCI), impact of perceived impairments on quality of life (QOL), perceived cognitive abilities (PCA), auditory-verbal learning test (AVLT) recognition and clock drawing test (CDT) were lower than those before chemotherapy (p < 0.05). In MRS, Ctx+ patients had significantly lower NAA values in bilateral PCG, DT, respectively. The concentrations of tCr were observed to decline in bilateral PCG and right DT. Glx values decreased in right DT. Cho values decreased significantly in bilateral DT. In DTI, Ctx+ patients had lower FA values in bilateral PCG compared with patients before chemotherapy. Among imaging metrics and cognitive scores, positive correlations were observed between changes in AVLT recognition scores and changes in NAA values in bilateral PCG (left PCG: r = 0.470, p < 0.01; right PCG: r = 0.500, p < 0.01). Positive correlations were also found between changes in AVLT recognition and changes in FA values in bilateral PCG (left PCG: r = 0.513, p < 0.01; right PCG: r = 0.563, p < 0.01). Chemotherapy can lead to a decrease in memory function, accompanied by changes in brain metabolite concentration and white matter integrity in some parts of brain.

Breast surgery and peripheral blocks. Is it worth it?

PURPOSE OF REVIEW: The objective of this review is to identify the potential of peripheral nerve blocks established over the last years for perioperative pain management in breast surgery. These new blocks will be discussed with respect to their clinical effect and necessity. RECENT FINDINGS: After case reports and cadaver studies for the Pecs block and its variations sufficient clinical data from randomized controlled trial (RCT) and meta-analyses exist now. The modified Pecs block or Pecs II leads to a reduction of postoperative 24-h opioid consumption. The recently invented Erector spine block addresses the intercostal nerves. The benefits in analgesia of this approach were tested in few RCTs and showed superiority to the control group in terms of requested postoperative morphine. Most studies showed low intraoperative opioid doses and no study more than low to moderate postoperative pain scores. SUMMARY: Taking the pain levels after breast surgery into account, the request of additional nerve blocks has to be pondered against the potential risks and resource requirement. To reduce or avoid intraoperative or postoperative opioids, an ultrasound-guided Pecs II block proves to be the best option for perioperative pain relief.

[A case of human adjuvant disease with clinical features of Guillain-Barré syndrome].

A 69-year-old female developed subacute diplopia, right peripheral facial nerve palsy, bilateral upper and lower extremities dysesthesia and weakness 50 years after silicone injection for breast augmentation. Motor conduction study revealed prolonged distal latency and reduced amplitude in the median, ulnar, and peroneal nerves. Sensory conduction velocities were reduced in the median and ulnar nerves, and sensory potential in the sural nerve could not be recorded. While intravenous immunoglobulin therapy was ineffective, explantation of silicone breast implants improved her neurological symptoms. Histopathological study of axillary lymph node revealed foreign body granulomas and macrophages phagocyting silicone. The patient was diagnosed with human adjuvant disease presenting clinical features of Guillain-Barré syndrome. Human adjuvant disease should be considered in the patients with implants like silicone and neurological symptoms.

Pathology of BRCA1- and BRCA2-associated Breast Cancers: Known and Less Known Connections.

INTRODUCTION: BRCA1/BRCA2 mutation carriers indefinitely comprise a distinct group of patients with breast cancer (BC), with their tumors displaying specific pathologic characteristics. Although these connections are known, they are not fully elucidated. We therefore sought to investigate the clinicopathologic characteristics and overall survival of Greek patients with BC carrying BRCA1/BRCA2 mutations. PATIENTS AND METHODS: Greek patients with BC diagnosed between 1999 and 2016, fulfilling the National Comprehensive Cancer Network criteria for genetic testing, were analyzed for BRCA1/BRCA2 mutations by Sanger sequencing or by a 94-gene panel. Medical records and pathology reports were retrospectively reviewed to retrieve patient and tumor baseline characteristics. Potential associations with mutation status were assessed using the Fisher exact, Pearson χ2, and Mann-Whitney tests. RESULTS: Of 2096 selected patients with BC, we identified 297 (14.2%) BRCA1 and 88 (4.2%) BRCA2 carriers. The mean age at BC diagnosis was 40 and 42.6 years, respectively (P = .02). Tumor histologic subtypes in BRCA1 and BRCA2 carriers were predominantly ductal (79%) followed by medullary (10%), and ductal (72%) followed by lobular (15%), respectively. A significantly higher percentage of BRCA2 tumors were human epidermal growth factor receptor 2-positive, compared with BRCA1 tumors (21.7% vs. 5.8%; P < .001). Second primary cancer diagnosis was more frequent in BRCA1 compared with BRCA2 mutation carriers (36.2% vs. 10.7%; P < .001), whereas there was no difference in 15-year overall survival (hazard ratio, 0.92; 95% confidence interval, 0.48-1.83; P = .804) between the 2 groups. CONCLUSIONS: These data confirm established observations in the pathology of BRCA-related tumors and provide further insight on the association of rare histologic entities with mutations in these genes, which can be clinically beneficial.

The Efficacy of Prophylactic Negative Pressure Wound Therapy for Closed Incisions in Breast Surgery: A Systematic Review and Meta-Analysis.

BACKGROUND: Negative pressure wound therapy (NPWT) is a promising advance in the management of closed surgical incisions. NPWT application induces several effects locally within the wound including reduced lateral tension and improving lymphatic drainage. As a result, NPWT may improve wound healing and reduce surgical site complications. We aim to evaluate the efficacy of prophylactic application of NPWT in preventing surgical site complications for closed incisions in breast surgery. METHODS: This systematic review was reported according to PRISMA guidelines. The protocol was published in PROSPERO (CRD42018114625). Medline, Embase, CINAHL and Cochrane Library databases were searched for studies which compare the efficacy of NPWT versus non-NPWT dressings for closed incisions in breast surgery. Specific outcomes of interest were total wound complications, surgical site infection (SSI), seroma, haematoma, wound dehiscence and necrosis. RESULTS: Seven studies (1500 breast incisions in 904 patients) met the inclusion criteria. NPWT was associated with a significantly lower rate of total wound complications [odds ratio (OR) 0.36; 95% CI 0.19-069; P = 0.002], SSI (OR 0.45; 95% CI 0.24-0.86; P = 0.015), seroma (OR 0.28; 95% CI 0.13-0.59; P = 0.001), wound dehiscence (OR 0.49; 95% CI 0.32-0.72; P < 0.001) and wound necrosis (OR 0.38; 95% CI 0.19-0.78; P = 0.008). There was no significant difference in haematoma rate (OR 0.8; 95% CI 0.19-3.2; P = 0.75). Statistically significant heterogeneity existed for total wound complications, but no other outcomes. CONCLUSION: Compared with conventional non-NPWT dressings, prophylactic application of NPWT is associated with significantly fewer surgical site complications including SSI, seroma, wound dehiscence and wound necrosis for closed breast incisions.

Breast Reduction Following Hormonal Therapy in a Transgender Female Patient.

In male-to-female gender transition, individuals request a number of interventions, including hormonal therapy, to promote feminizing characteristics. Estrogen-based medication is prescribed to increase breast development, decrease facial hair, promote feminine adipose tissue deposition, and soften skin. Surgical breast augmentation to supplement unsatisfying breast growth after hormonal therapy is a common and well-studied course of management for such transgender patients. In a departure from convention, the authors present a case of symptomatic macromastia requiring surgical breast reduction in a transgender woman following 24 years of hormonal therapy and illicit silicone injections in multiple areas of her body, including the breasts.

Is opioid-free general anesthesia for breast and gynecological surgery a viable option?

PURPOSE OF REVIEW: Opioid-free anesthesia (OFA) was introduced to avoid tolerance and hyperalgesia, allowing reduction in postoperative opioids. OFA focused initially on postoperative respiratory safety for patients undergoing ambulatory surgery and for obstructive sleep apnea syndrome patients otherwise requiring intensive care admission. What about using OFA in plastic and oncological breast surgery, in deep inferior epigastric perforators flap surgery, and in gynecological laparoscopy? RECENT FINDINGS: OFA requires the use of other drugs to block the unwanted reactions from surgical injury. This can be achieved with a single drug at a high dose or with a combination of different drugs at a lower dose, such as with alpha-2-agonists, ketamine, lidocaine, and magnesium, each working on a different target and therefore described as multitarget anesthesia. Three factors can explain OFA success: improved analgesia with less postoperative opioids, the near absence of postoperative nausea and vomiting if no opioid is needed postoperatively, and reduced inflammation enhancing the recovery after surgery. SUMMARY: Opioid-free general anesthesia is a viable option for breast and gynecological surgery and its use will only increase when anesthesiologists listen to their patients' experiences after undergoing surgery under general anesthesia.

Aromatherapy for Preoperative Anxiety: A Pilot Study.

PURPOSE: The aim of this study was to evaluate the use of a lavender aromatherapy skin patch on anxiety and vital sign variability during the preoperative period in female patients scheduled for breast surgery. DESIGN: This observational pilot study used a one-group, pretest and post-test design. METHODS: Participants received an aromatherapy patch in addition to standard preoperative care. Anxiety levels were assessed with a 10-cm visual analog scale at baseline and then every 15 minutes after patch placement. Vital sign measurements were recorded at the same interval. FINDINGS: There was a statistically significant decrease (P = .03) in the anxiety visual analog scale measurements from baseline to final scores. CONCLUSIONS: Findings from this study suggest the use of aromatherapy is beneficial in reducing anxiety experienced by females undergoing breast surgery. Further research is needed to address the experience of preoperative anxiety, aromatherapy use, and the challenges of managing preoperative anxiety.
