Surgical Management of Postoperative Nipple Necrosis After Inverted Nipple Correction: Experiences From a Series of 25 Cases.

INTRODUCTION: The inverted nipple is a condition that affects approximately 10% of women and can have negative cosmetic and psychological implications. Surgical correction is a common approach to address this concern; however, this method can lead to complications, such as nipple necrosis. As comprehensive guidelines are currently lacking for postoperative nipple necrosis management, this study reports our experience in the management of postoperative nipple necrosis following initial attempt at surgical management. METHODS: A retrospective chart review was conducted and included female patients who experienced postoperative nipple necrosis after inverted nipple correction between 2018 and 2021. Cases of recurrent nipple retraction following partial necrosis and cases of complete nipple necrosis were evaluated. Recurrent nipple retraction was managed using various inverted nipple correction techniques, while complete necrosis required a modified C-V flap for nipple reconstruction. RESULTS: A total of 25 patients with a total of 42 affected nipples were included. Thirteen cases (26 nipples) experienced recurrent nipple retraction following partial necrosis, while 12 cases (16 nipples) exhibited complete necrosis. No significant predictive variables for these complications were found. Notably, all patients achieved successful healing following single-stage surgical repair. At 6 months postoperation, the treated nipples exhibited satisfactory healing and appearance and an absence of infection or papillary necrosis. Seven reconstructed nipples showed a mean loss of projection (2.7 ± 0.98) compared with only 2 nipples in the inverted nipple correction group. CONCLUSIONS: Distinguishing between recurrent nipple retraction after partial necrosis and complete nipple necrosis is crucial and should be taken into consideration when managing patients following inverted nipple correction.

The effect of interventions on flat and inverted nipple on breastfeeding: A systematic review.

BACKGROUND: Some methods have been developed to solve flat and/or inverted nipple problems. This study aimed to examine the effects of flat and/or inverted nipple interventions on nipples and breastfeeding. METHODS: Before initiating the review, the protocol was registered in the 'PROSPERO' database. This study was based on the PRISMA-P guideline. Seven databases (Web of Science, PubMed, ScienceDirect, Scopus, The Cochrane Library, TÜBITAK Ulakbim and Google Scholar) were searched, and nine studies were included in this review. RESULTS: Hoffman's exercise, the inverted syringe method, and the nipple exercise was quite effective in increasing breastfeeding success. The rate of exclusive breastfeeding in the first, third, and sixth months of mothers followed up with postpartum multidimensional visits was found to be significantly higher in the intervention group than in the control group (p < 0.05). A study in which a rubber band was applied with the help of an injector on flat and inverted nipples showed that 63% of mothers on the third day and all of them in the first month were able to breastfeed without a rubber band. Hoffman's exercise, the inverted syringe technique, and rubber bands corrected the flat and/or inverted nipple. There were studies reporting complications as a result of nipple interventions. CONCLUSIONS AND IMPLICATIONS: It is necessary to disseminate the information that breastfeeding of mothers with flat and/or inverted nipples can be sustained with various interventions. Furthermore, it is believed that providing mothers with a chance to choose the interventions, and thus, the compliance of mothers to the intervention with the method of their choice may increase the success of the intervention.

Breastfeeding Outcome and Complications in Females With Breast Implants: A Systematic Review and Meta-Analysis.

Breast augmentation is a commonly performed cosmetic procedure. We set out to determine whether there was any effect on breastfeeding in females after breast implants. The aim of this study was to perform a systematic review and meta-analysis of the current evidence on breastfeeding outcome and complications in females with breast augmentation. A systematic review was performed utilizing MEDLINE, EMBASE, and all evidence-based medicine reviews from their respective inception dates to November 7, 2022, to assess outcomes of breastfeeding in females with breast implants (PROSPERO ID: CRD42022357909). This review was in accordance with both the Cochrane Handbook for Systematic Review of Interventions and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Eleven studies (4 prospective and 7 retrospective) in total were included in the review. A total of 8197 out of 9965 (82.25%) patients were successfully able to breastfeed after breast implants. Of 5 studies that included a control group, 343,793 of 388,695 (88.45%) women without breast implants successfully breastfed. A meta-analysis of 5 comparative studies showed a significant reduction of breastfeeding in females with breast implants, n = 393,686, pooled odds ratio = 0.45 (95% CI, 0.38 to 0.53). Complications described included pain, mastitis, insufficient or excessive lactation, and nipple inversion. There may be impairment in ability to breastfeed for females who receive breast implants when compared with those without. Additional studies on the topic are needed to further clarify the relationship.

Early life body size, pubertal timing, and risks of benign breast disease in a large cohort of Danish female adolescents and women.

A high childhood body mass index (BMI) may be protective against benign breast disease (BBD), but little is known about the effects of other early life body size measures. Thus, we examined associations between birthweight, childhood BMI, height, and pubertal timing and BBD risks. We included 171,272 girls, born from 1930 to 1996, from the Copenhagen School Health Records Register, which contains information on birthweight, childhood anthropometry (7-13 years), age at onset of the growth spurt (OGS), and peak height velocity (PHV). During follow-up, 9361 BBD cases (15-50 years) were registered in the Danish National Patient Register. Hazard ratios (HR) and 95% confidence intervals (CI) were estimated by Cox regressions. At all childhood ages, BMI was inversely but non-linearly associated with BBD. The association was slightly stronger in magnitude for BMI z-scores above 0 (HRage 7 = 0.86; 95%CI: 0.83-0.90 per z-score) than below 0 (HRage 7 = 0.95; 95%CI 0.91-0.99 per z-score). Associations between childhood height and BBD differed by age; at 7 years the association was an inverted U-shape, whereas at 13 years height was not associated with BBD. Ages at OGS and PHV were positively associated with BBD. Low and high birthweights were associated with lower BBD risks.   Conclusion: A high childhood BMI, a short or tall stature at young childhood ages, an early pubertal onset, and low or high birthweights are associated with reduced risks of BBD. These complex associations suggest that the role of these factors in breast tissue development during early life warrants further investigation in relation to BBD etiology. What is Known: • Benign breast disease (BBD) is common and may be an intermediary marker of breast cancer risks. • Early life body size may relate to the development of BBD, but currently little is known. What is New: • Girls with a high body mass index at school ages or with an early pubertal timing have decreased risks of BBD. • Short and tall heights at young childhood ages and low and high birthweights are associated with lower BBD risks.

Application of arthroscopic system in the treatment of lactational breast abscess.

PURPOSE: Optimal treatment of breast abscesses has been controversial. Herein, we report an innovative method for the operative treatment of lactational mammary abscesses. METHODS: Nineteen lactating patients diagnosed with breast abscesses were enrolled in the study, and abscess debridement and drainage were performed using an arthroscopic system. The clinical characteristics of the patients were recorded to evaluate the feasibility, efficacy, and cosmetic results of arthroscopic surgery for breast abscesses. RESULTS: All 19 patients were cured and did not relapse within the 6-month-follow-up period. One patient stopped breastfeeding due to breast leakage. All patients were satisfied with the postoperative appearance of the breast. CONCLUSION: Arthroscopic debridement and drainage are effective treatment methods for lactational breast abscesses, with a high cure rate, few complications, and satisfactory cosmetic outcomes.

Infiltrating immune cells in benign breast disease and risk of subsequent invasive breast cancer.

BACKGROUND: It is well established that tumors are antigenic and can induce an immune response by the host, entailing lymphocytic infiltration of the tumor and surrounding stroma. The extent and composition of the immune response to the tumor, assessed through evaluation of tumor-infiltrating lymphocyte counts, has been shown in many studies to have prognostic and predictive value for invasive breast cancer, but currently, there is little evidence regarding the association between infiltrating immune cell counts (IICCs) in women with benign breast disease (BBD) and risk of subsequent invasive breast cancer. METHODS: Using a cohort of 15,395 women biopsied for BBD at Kaiser Permanente Northwest, we conducted a nested case-control study in which cases were women who developed a subsequent invasive breast cancer during follow-up and controls were individually matched to cases on age at BBD diagnosis. We assessed IICCs in normal tissue and in the BBD lesions, and we used unconditional logistic regression to estimate the multivariable odds ratios (OR) and 95% confidence intervals (CI) for the associations between IICCs and breast cancer risk. RESULTS: There was no association between the IICC in normal tissue (multivariable OR per 5% increase in IICC = 1.05, 95% CI = 0.96-1.16) or in the BBD lesion (OR per 5% increase in IICC = 1.06, 95% CI = 0.96-1.18) and risk of subsequent invasive breast cancer. Also, there were no associations within subgroups defined by menopausal status, BBD histology, BMI, and history of smoking. CONCLUSION: The results of this study suggest that IICCs in BBD tissue are not associated with altered risk of subsequent invasive breast cancer.

Predictors of mammographic microcalcifications.

We examined the association between established risk factors for breast cancer and microcalcification clusters and their asymmetry. A cohort study of 53 273 Swedish women aged 30 to 80 years, with comprehensive information on breast cancer risk factors and mammograms, was conducted. Total number of microcalcification clusters and the average mammographic density area were measured using a Computer Aided Detection system and the STRATUS method, respectively. A polygenic risk score for breast cancer, including 313 single nucleotide polymorphisms, was calculated for those women genotyped (N = 7387). Odds ratios (ORs) and 95% confidence intervals (CIs), with adjustment for potential confounders, were estimated. Age was strongly associated with microcalcification clusters. Both high mammographic density (>40 cm2 ), and high polygenic risk score (80-100 percentile) were associated with microcalcification clusters, OR = 2.08 (95% CI = 1.93-2.25) and OR = 1.22 (95% CI = 1.06-1.48), respectively. Among reproductive risk factors, life-time breastfeeding duration >1 year was associated with microcalcification clusters OR = 1.22 (95% CI = 1.03-1.46). The association was confined to postmenopausal women. Among lifestyle risk factors, women with a body mass index ≥30 kg/m2 had the lowest risk of microcalcification clusters OR = 0.79 (95% CI = 0.73-0.85) and the association was stronger among premenopausal women. Our results suggest that age, mammographic density, genetic predictors of breast cancer, having more than two children, longer duration of breast-feeding are significantly associated with increased risk of microcalcification clusters. However, most lifestyle risk factors for breast cancer seem to protect against presence of microcalcification clusters. More research is needed to study biological mechanisms behind microcalcifications formation.

Cytotoxic T cell depletion with increasing epithelial abnormality in women with benign breast disease.

PURPOSE: We quantified cytotoxic T cells in nonmalignant breast tissues from women with and without subsequent breast cancer to assess evidence of whether immunosurveillance may be suppressed prior to tumor development. METHODS: We used an age-matched set of breast tissues from women with benign breast disease (BBD) who subsequently developed breast cancer (BBD with later BC), women with BBD who remained cancer free (BBD cancer-free), and normal Komen Tissue Bank (KTB) tissue donors (KTB controls). We evaluated terminal duct lobular units (lobules) for degree of epithelial abnormality and density of dual-positive CD8/CD103 T cells, as CD103+ cells are thought to be a subset of CD8+ cytotoxic T cells located primarily in the intraepithelial compartment. RESULTS: In 10 sets of age-matched women, 256 breast lobules were studied: 85 in BBD women with later BC, 85 in BBD cancer-free women, and 86 in KTB donors. The majority of all lobules were histologically normal (N = 143, 56%), with 65 (25%) nonproliferative fibrocystic change, and 48 (19%) proliferative epithelial change (with or without atypia). In BBD women with later BC, median CD8+/CD103+ cell density was 39.6, 31.7, and 10.5 cells/mm2 (p = 0.002) for normal, nonproliferative, and proliferative lobules. In BBD cancer-free women, median CD8+/CD103+ cell density values were 46.7, 14.3, and 0 cells/mm2 (p = 0.004) respectively. In KTB donors, CD8+/CD103+ cell density was not significantly different across the lobule types (medians 0, 5.8, 10.7, p = 0.43). CONCLUSION: In women with BBD, breast lobules with increasing epithelial abnormality show significant decreases in cytotoxic T cells as measured by CD8/CD103 staining, suggesting that impaired immunosurveillance may be a component of the earliest stages of breast cancer development.

Treatments for breast engorgement during lactation.

BACKGROUND: Engorgement is the overfilling of breasts with milk, often occurring in the early days postpartum. It results in swollen, hard, painful breasts and may lead to premature cessation of breastfeeding, decreased milk production, cracked nipples and mastitis. Various treatments have been studied but little consistent evidence has been found on effective interventions. OBJECTIVES: To determine the effectiveness and safety of different treatments for engorgement in breastfeeding women. SEARCH METHODS: On 2 October 2019, we searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP), and reference lists of retrieved studies. SELECTION CRITERIA: All types of randomised controlled trials and all forms of treatment for breast engorgement were eligible. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trials for eligibility, extracted data, conducted 'Risk of bias' assessment and assessed the certainty of evidence using GRADE. MAIN RESULTS: For this udpate, we included 21 studies (2170 women randomised) conducted in a variety of settings. Six studies used individual breasts as the unit of analysis. Trials examined a range of interventions: cabbage leaves, various herbal compresses (ginger, cactus and aloe, hollyhock), massage (manual, electromechanical, Oketani), acupuncture, ultrasound, acupressure, scraping therapy, cold packs, and medical treatments (serrapeptase, protease, oxytocin). Due to heterogeneity, meta-analysis was not possible and data were reported from single trials. Certainty of evidence was downgraded for limitations in study design, imprecision and for inconsistency of effects. We report here findings from key comparisons. Cabbage leaf treatments compared to control For breast pain, cold cabbage leaves may be more effective than routine care (mean difference (MD) -1.03 points on 0-10 visual analogue scale (VAS), 95% confidence intervals (CI) -1.53 to -0.53; 152 women; very low-certainty evidence) or cold gel packs (-0.63 VAS points, 95% CI -1.09 to -0.17; 152 women; very low-certainty evidence), although the evidence is very uncertain. We are uncertain about cold cabbage leaves compared to room temperature cabbage leaves, room temperature cabbage leaves compared to hot water bag, and cabbage leaf extract cream compared to placebo cream because the CIs were wide and included no effect. For breast hardness, cold cabbage leaves may be more effective than routine care (MD -0.58 VAS points, 95% CI -0.82 to -0.34; 152 women; low-certainty evidence). We are uncertain about cold cabbage leaves compared to cold gel packs because the CIs were wide and included no effect. For breast engorgement, room temperature cabbage leaves may be more effective than a hot water bag (MD -1.16 points on 1-6 scale, 95% CI -1.36 to -0.96; 63 women; very low-certainty evidence). We are uncertain about cabbage leaf extract cream compared to placebo cream because the CIs were wide and included no effect. More women were satisfied with cold cabbage leaves than with routine care (risk ratio (RR) 1.42, 95% CI 1.22 to 1.64; 152 women; low certainty), or with cold gel packs (RR 1.23, 95% CI 1.10 to 1.38; 152 women; low-certainty evidence). We are uncertain if women breastfeed longer following treatment with cold cabbage leaves than routine care because CIs were wide and included no effect. Breast swelling and adverse events were not reported. Compress treatments compared to control For breast pain, herbal compress may be more effective than hot compress (MD -1.80 VAS points, 95% CI -2.07 to -1.53; 500 women; low-certainty evidence). Massage therapy plus cactus and aloe compress may be more effective than massage therapy alone (MD -1.27 VAS points, 95% CI -1.75 to -0.79; 100 women; low-certainty evidence). In a comparison of cactus and aloe compress to massage therapy, the CIs were wide and included no effect. For breast hardness, cactus and aloe cold compress may be more effective than massage (RR 0.66, 95% CI 0.51 to 0.87; 102 women; low-certainty evidence). Massage plus cactus and aloe cold compress may reduce the risk of breast hardness compared to massage alone (RR 0.38, 95% CI 0.25 to 0.58; 100 women; low-certainty evidence). We are uncertain about the effects of compress treatments on breast engorgement and cessation of breastfeeding because the certainty of evidence was very low. Among women receiving herbal compress treatment, 2/250 experienced skin irritation compared to 0/250 in the hot compress group (moderate-certainty evidence). Breast swelling and women's opinion of treatment were not reported. Medical treatments compared to placebo Protease may reduce breast pain (RR 0.17, 95% CI 0.04, 0.74; low-certainty evidence; 59 women) and breast swelling (RR 0.34, 95% CI 0.15 to 0.79; 59 women; low-certainty evidence), whereas serrapeptase may reduce the risk of engorgement compared to placebo (RR 0.36, 95% CI 0.14 to 0.88; 59 women; low-certainty evidence). We are uncertain if serrapeptase reduces breast pain or swelling, or if oxytocin reduces breast engorgement compared to placebo, because the CIs were wide and included no effect. No women experienced adverse events in any of the groups receiving serrapeptase, protease or placebo (low-certainty evidence). Breast induration/hardness, women's opinion of treatment and breastfeeding cessation were not reported. Cold gel packs compared to control For breast pain, we are uncertain about the effectiveness of cold gel packs compared to control treatments because the certainty of evidence was very low. For breast hardness, cold gel packs may be more effective than routine care (MD -0.34 points on 1-6 scale, 95% CI -0.60 to -0.08; 151 women; low-certainty evidence). It is uncertain if women breastfeed longer following cold gel pack treatment compared to routine care because the CIs were wide and included no effect. There may be little difference in women's satisfaction with cold gel packs compared to routine care (RR 1.17, 95% CI 0.97 to 1.40; 151 women; low-certainty evidence). Breast swelling, engorgement and adverse events were not reported. AUTHORS' CONCLUSIONS: Although some interventions may be promising for the treatment of breast engorgement, such as cabbage leaves, cold gel packs, herbal compresses, and massage, the certainty of evidence is low and we cannot draw robust conclusions about their true effects. Future trials should aim to include larger sample sizes, using women - not individual breasts - as units of analysis.

Ischemic necrosis of the breast following septic shock: A case report.

Fat necrosis of the breast is a common and benign entity, often secondary to trauma, surgery, radiation therapy, or unknown etiologies. Critically ill patients with septic shock may experience end-organ hypoperfusion and tissue infarction and necrosis, which may result in breast fat necrosis, however, to the best of our knowledge this has not been previously described. We report a case of biopsy-proven breast fat necrosis secondary to septic shock following an emergency surgery in a postmenopausal female.

Microchipping the breast: an effective new technology for localizing non-palpable breast lesions for surgery.

PURPOSE: Use of a wire to localize a non-palpable breast lesion for surgery is standard but archaic. We sought to evaluate a new radiofrequency localization system (RFLS) as an effective, non-radioactive alternative to the wire. METHODS: Patients who required surgical excision of a non-palpable breast lesion were consented for the study. Patients underwent localization with a radiofrequency Tag and surgical removal guided by the handheld LOCalizer probe. The primary study endpoint was successful placement and retrieval of the Tag, and secondary endpoints included marker migration; days prior to surgery of Tag insertion; patient, radiologist, and surgeon experience; distance of Tag from skin; and positive margin and re-excision rates for cancer. RESULTS: Fifty patients had successful placement and retrieval of the radiofrequency Tag. Likert questionnaire data revealed that most patients thought the procedure went smoothly and was easier than expected. Radiologists and surgeons thought that the Tag was as reliable as the wire. Of the 33 patients who had surgery for in situ or invasive cancer, one had a positive margin on final pathology (3%) and two underwent re-excision (6%). CONCLUSIONS: Data from this pilot study suggest that the RFLS is an effective localization system for non-palpable breast lesions intended for surgical removal. Unlike most other technologies, the LOCalizer probe detects distance from the Tag, and this unique feature may have contributed to the low positive margin rate seen in this study. The RFLS appears to offer advantages over current localization procedures and should be explored as an alternative to wire. ClinicalTrials.gov Identifier: NCT03202472.

Dietary intake from birth through adolescence in relation to risk of benign breast disease in young women.

PURPOSE: Nutritional factors during different periods in life impact breast cancer risk. Because benign breast disease (BBD) is a well-established risk factor for breast cancer, we investigated childhood nutrition from birth through age 14 year and subsequent BBD. METHODS: A prospective cohort study of 9031 females, 9-15 year at baseline, completed questionnaires (including heights, weights) annually from 1996 to 2001, in 2003, 2005, 2007, 2010, 2013 and 2014. In 1996, mothers reported infant feeding practices during their daughters first year of life. Beginning in 1996, participants completed annual food frequency questionnaires. In 2005, participants (18 year +) began reporting whether they had ever been diagnosed with biopsy-confirmed BBD (N = 173 cases). Multivariable logistic regression models estimated associations between childhood nutrition and BBD, adjusted for maternal breast disease and childhood body size factors. RESULTS: Although no infant nutrition factors were associated with biopsy-confirmed BBD, certain adolescent dietary factors were. A multivariable model simultaneously included the most important diet and body size factors from different age periods: higher BBD risk was associated with greater age 10 year consumption of animal (non-dairy, energy-adjusted) fat (OR 2.27, p < .02, top vs. bottom quartiles) and with lower 14 year consumption of nuts/peanut butter (OR 0.60, p = .033, top vs. bottom quartiles). CONCLUSION: Greater intake of animal (non-dairy) fat at 10 year and lower intake of nuts/peanut butter at 14 year were independently associated with higher BBD risk. These dietary factors appeared to operate on BBD risk independent of childhood growth (gestational weight gain, childhood BMI and height, adolescent height growth velocity), young adult height and BMI, and family history.

Psychosocial stress is associated with benign breast disease in young Chinese women: results from Project ELEFANT.

PURPOSE: Psychosocial stress, including bereavement and work-related stress, is associated with the risk of breast cancer. However, it is unknown whether it may also be linked with increased risk of benign breast disease (BBD). METHODS: Our study leveraged 61,907 women aged 17-55 years old from the Project ELEFANT study. BBD was diagnosed by clinician. Self-reported data on psychosocial stress over a 10-year period was retrospectively collected from questionnaires and categorised by cause (work, social and economic) and severity (none, low and high). Odd ratios (ORs) for the development of BBD were estimated using logistic regression. The model was adjusted for age, BMI, TSH levels, smoking, alcohol consumption, family history, age of menarche, oral contraceptive usage, education and occupation. RESULTS: Within our study, 8% (4,914) of participants were diagnosed with BBD. Work-related stress [OR 1.57, 95% confidence interval (CI) 1.46-1.69] and financial stress (OR 1.34, 95% CI 1.24-1.44) were significantly associated with BBD incidence, with a smaller but still significant association with social stress (OR 1.11, 95% CI 1.01-1.21). The associations remained significant after exclusion of participants with first- and second-degree family history of breast disease. The presence of multiple forms of stress did not synergistically increase risk. The neutrophil-lymphocyte ratio (NLR), a marker of systemic inflammation and prognostic marker for breast cancer, was not associated with BBD. CONCLUSIONS: Psychosocial stress, particularly work-related and financial stress, is associated with increased risk of benign breast disease among young Chinese women.

Mammillary fistula revisited: Implications for immediate breast reconstruction.

We present two patients with inverted nipples who underwent bilateral nipple-sparing mastectomies (NSM) with immediate placement of tissue expanders with acellular dermal matrix (ADM). Both were complicated by postoperative infection and developed mammillary fistulae from the nipple into the breast capsule, and eroding through the ADM. For the first time, we report inverted nipples as a risk for the iatrogenic formation of mammillary fistulae and their infectious implications after NSM.

Prepectoral Wise-Pattern Staged Implant-Based Breast Reconstruction for Obese or Ptotic Patients.

INTRODUCTION: The obese or ptotic breast demonstrates significant difficulty in breast reconstruction after mastectomy with increased rates of perioperative complications compared with the general population, regardless of reconstruction type. Implant-based reconstruction in this patient population with the traditional horizontal elliptical skin-sparing mastectomy tends to have aesthetically displeasing qualities secondary to skin flap redundancy and blunting of the breast contour. Wise-pattern closures have been described with submuscular direct-to-implant and 2-stage reconstructions, with more favorable complication profile when staged. Our study aims to report outcomes and safety of a prepectoral 2-stage wise-pattern closure technique in the obese and/or ptotic population. METHODS: A retrospective chart review was performed to identify all overweight, obese, and/or grade III ptotic patients who have undergone a 2-stage, wise-pattern skin closure with prepectoral placement of tissue expander by a single surgeon. Patient demographics, comorbidities, and perioperative descriptors were reported. Delayed wound healing, infection, seroma formation, and explantation or reoperation were recorded for each patient involved in the study. RESULTS: Thirty-seven obese and/or ptotic breasts among 21 patients underwent immediate prepectoral tissue expander placement with wise-pattern skin reduction closure with mean body mass index of 35.3 kg/m, and 25% of patients were diabetic The most common complication rates by breast were seroma formation (50%) and wound/dehiscence at T-point (28.6%), which all ultimately healed with intervention as described. One major (2.7%) and 1 minor (2.7%) infection were successfully treated with antibiotics. There were no cases of implant exposure. Two operative complex repairs and 1 elective explantation were performed. Diabetes and increasing body mass index were statistically associated with an increased overall perioperative complication rate. CONCLUSIONS: Prepectoral, 2-stage breast reconstruction with wise-pattern skin reduction performs well in obese and/or ptotic patients with favorable rates of perioperative complications. Wound dehiscence was prevalent but managed with wound care when complex repair was not required to expedite adjuvant chemotherapy. Infection rates and reoperation rates were low, and all patients reported positive aesthetic results at the completion of reconstruction.

Post-traumatic necrotising fasciitis of the breast: a case study with literature review.

Necrotising fasciitis is a rare infection of the skin and underlying soft tissue. It primarily involves the extremities and rarely the breast. Primary necrotising fasciitis of the breast in a non-lactating, healthy female is rarer still. The authors present the case report of a patient presenting with primary necrotising fasciitis of the breast after sustaining a penetrating injury. The patient was managed successfully with serial debridement and negative pressure wound therapy (NPWT). To our knowledge only 19 such cases have been reported in the indexed literature so far. This is also the eighth case globally of primary necrotising fasciitis of the breast in a non-lactating female without any associated immunosuppression, which is the basis of reporting this case.

Breast Reduction and Mastopexy for Repair of Asymmetry After Breast Conservation Therapy: Lessons Learned.

BACKGROUND: Breast conservation therapy (BCT) can cause breast distortion and asymmetry. Repair of this asymmetry by means of breast reduction or mastopexy procedures can be challenging and harbor considerably high rates of complications. METHODS: In this retrospective study, we describe our experience in repairing post-BCT breast asymmetry by performing breast reduction or mastopexy. The surgical protocol we followed consisted of stringent patient selection, thorough surgical planning, basic surgical refinements, and patient education for enhancing the likelihood of achieving a good outcome with minimal surgical complications. RESULTS: Our search of the departmental database identified 25 patients with breast asymmetry who had undergone breast reduction or mastopexy between 2009 and 2017. Corrective surgery was performed 4 years on average after the completion of radiotherapy, and those patients included eleven who had undergone breast reduction and fourteen who had undergone mastopexy on the radiated side. Two patients (8%) had major complications that required further surgery (major fat necrosis, wound infection, and breast deformation), and five patients (20%) had minor complications (infection, minor fat necrosis, wound dehiscence, and nipple congestion). All complications developed on the radiated breast. There was no correlation between the occurrence of complications and patients' demographics, tumor type, tumor location, and breast tissue resection (p > 0.05). CONCLUSION: Only two of our 25 patients had major complications following breast reduction and mastopexy for the repair of asymmetry post-BCT. Following our four-step protocol was instrumental in leading to the successful performance of these procedures.

The Vacuum-Assisted Breast Biopsy System is an Effective Treatment Strategy for Breast Lumps After Augmentation with Autologous Fat Grafting.

BACKGROUND: With the extensive application of autologous fat grafting (AFG) to the breasts, postoperative complications such as breast lumps attract high attention. Breast lumps greatly reduce patient satisfaction and bring mental stress. However, there are few detailed reports about minimally invasive treatment strategies for breast lumps after AFG. Our study aimed to investigate the effectiveness of the vacuum-assisted breast biopsy (VABB) system for patients with lumps after AFG. MATERIALS AND METHODS: We retrospectively reviewed 37 patients with breast lumps between April 2015 and January 2019. The characteristics of patients and breast lumps were analyzed. Breast lumps were classified into four types, including cystic, solid, complex and calcification. The vacuum-assisted breast biopsy (Mammotome and Encor) was performed for the patients with lumps after AFG. The efficacy, safety, complications and patient satisfactions were recorded during postoperative follow-up periods. RESULTS: Under the guidance of ultrasound, the breast lumps could be thoroughly and accurately excised by the vacuum-assisted biopsy system. No patient experienced breast infections or major complications requiring treatment. Hematoma was observed in only 2 patients and gradually resolved without any special management. With a median follow-up of 29 months, no recurrence was observed. Furthermore, there were no statistical differences in duration of the procedures and complications between the two VABB systems. All the patients recovered well and were satisfied with the cosmetic outcome. CONCLUSION: The vacuum-assisted breast biopsy system can be used as an effective and minimally invasive approach for the surgical management of lumps after AFG.

Iatrogenic Symmastia: Causes and Suggested Repair Technique.

BACKGROUND: Various theories exist to explain the etiology of iatrogenic symmastia. Subglandular over-dissection of the medial breast pocket over the sternum, disruption of midline sternal fascia, oversized implant base diameter, and over-dissection of the medial pectoralis muscle attachments to the sternum are popular explanations. OBJECTIVES: The authors hypothesized that the most common risk factor for iatrogenic symmastia is subpectoral breast augmentation. METHODS: A retrospective chart review was conducted including all symmastia patients who underwent surgery from January 2008 to April 2018 by a single surgeon (C.L.M.). ASAPS members were also surveyed regarding the etiology and incidence of symmastia in their practice. RESULTS: Twenty-three patients with symmastia were included in the retrospective chart review. All had previous subpectoral breast augmentation. In the ASAPS survey, 91 plastic surgeons reported seeing an average of 2.2 consults for acquired symmastia over the preceding year; 1.9 of the 2.2 (84.9%) acquired symmastia consults previously underwent subpectoral breast augmentation. Most surgeons attributed these patients' symmastia to over-dissection of the medial pectoralis muscle attachments to the sternum. CONCLUSIONS: Symmastia is most often caused by pectoralis major sternal dehiscence during subpectoral breast augmentation. In the senior author's experience, all patients with iatrogenic symmastia previously had a submuscular breast augmentation. The ASAPS survey supports multiple causes for symmastia with retromuscular breast augmentation occurring in the majority of patients. Repair of symmastia should include securing Scarpa's fascia to the sternum, reattaching the pectoralis major to the sternum, avoiding another subpectoral implant, and using postoperative modalities to protect the repair.

Iatrogenic Arteriovenous Fistula of the breast following core-biopsy presenting in pregnancy.

Core-biopsy of the breast is the standard of care for assessment of breast lumps. It is rarely associated with a vascular injury resulting in the formation of an arteriovenous fistula. Though previously noted in the medical literature, it has never been reported in the context of pregnancy and lactation.
