Introduction: PlasmaBlade® is a thermal dissection device that may allow for improved perfusion of the mastectomy flap by limiting thermal injury. In this study we aim to compare the mastectomy flap perfusion using PlasmaBlade® versus traditional electrocautery. Methods: Patients undergoing bilateral mastectomy with immediate breast reconstruction were recruited. The right and left breasts of each patient were randomized to dissection with PlasmaBlade® or standard electrocautery. Randomization was performed using random sequences on the day of surgery and was blinded to the plastic surgeon. Mastectomy flap perfusion was assessed following completion of the mastectomy using intra-operative fluoroscopy and plastic surgeon review. Surgical site drainage and pain score were measured. Sign tests were employed to assess differences in perfusion and Wilcoxon paired test for the secondary outcomes. Results: Twenty patients were enrolled in the study with median age of 40.5 years and median BMI of 26 kg/m2. In 18 patients (90%), perfusion was assessed to be better on the side of the PlasmaBlade® dissection. Median daily drainage over a 7-day period was 51 cc (IQR 35–61) on the PlasmaBlade® side and 44 cc (IQR 31–61) on the control side. Median pain score on the PlasmaBlade® side was 4.0 (IQR 2.3–5.9) and 4.4 (IQR 2.9–6) on the control side. No skin necrosis was noted in either groups. Conclusion: Use of PlasmaBlade® appears to be a safe and reliable technique to perform mastectomy and breast reconstruction with equivalent outcomes to traditional electrocautery. Although, mastectomy skin flap perfusion was rated better intra-operatively for the PlasmaBlade® group, both cohorts had comparable outcomes.

Background: Breast reduction is a commonly performed procedure. Understanding the postoperative complication profile is important for preoperative planning and patient education.Objectives: The authors sought to assess complication rates following breast reduction in females and identify potential risk factors.Methods: We assessed the records of the American College of Surgeons National Surgical Quality Improvement Program participant use files that include patients who underwent breast reduction for macromastia between 2005 and 2016. Relevant patient and postoperative data were extracted, and factors affecting complications were analyzed utilizing the logistic regression model.Results: We identified 20,001 women aged a mean 43.9 years who underwent breast reduction. The number of patients who developed ≥1 complication was 1009 (4.3%). Our adjusted analysis revealed that outpatient setting (odds ratio [OR] = 0.600) and performance of the surgery by the attending surgeon alone (OR = 0.678) were associated with lower odds, whereas higher body mass index (OR = 1.046) and smoking (OR = 1.518) were associated with higher odds for complications following breast reduction. Outpatient setting (OR = 0.317) was also associated with lower odds whereas smoking (OR = 1.613) and American Society of Anesthesiologists class were associated with higher odds of returning to the operative room. These findings were consistent in our subgroup analysis for wound-related complications.Conclusions: Our study shows that patient characteristics such as smoking and body mass index may increase complication rates after breast reduction. Clinical factors such as inpatient setting may also increase risk of complications following breast reduction. It is critical to understand the effect of these factors to better predict postoperative outcomes and ensure thorough patient education. [ABSTRACT FROM AUTHOR]

Plastic surgeons offer various options for breast reconstruction based on patient preference, underlying disease, and comorbidities. An alternative form of breast reconstruction exists, which includes tissue expansion with tissue expander and subsequent fat grafting without the use of implant or flap. We retrospectively reviewed the breast cancer patients who underwent breast reconstruction at our institution to identify those with pure fat grafting. Demographic information, complications, operative details, and BREAST‐Q scores were abstracted. From 2010‐2015, 10 patients were identified. Patients with unilateral or bilateral mastectomy followed by pure fat grafting had a median of 3.5 or 4 sessions and a total median fat grafting volume of 380 or 974.5 cc, respectively. Patients were followed for 12 months, and no complications or breast cancer recurrences were noted. Finally, BREAST‐Q scores at the 12‐month follow‐up were comparable to the preoperative values.

Background: Malpractice litigation has a significant impact on healthcare costs and important professional implications for healthcare providers.Objectives: The authors sought to comprehensively characterize the litigation landscape in plastic surgery across its different subspecialties.Methods: The authors utilized the Westlaw legal database to conduct a comprehensive search of malpractice cases in the United States in the following categories: cosmetic, reconstructive, hand, craniofacial, and gender affirmation surgery. They conducted both a Boolean and a natural language search to identify cases in which a plastic surgeon was the defendant. Data were analyzed employing descriptive statistics, logistic regression, and relative risk calculations.Results: In total, 165 cases were included. Most surgeons accused of malpractice worked in a private setting (148 [90%]). Among the 22 (13%) cases that contained information on board certification status, most surgeons were board certified (17 [77%]). Resident involvement was mentioned in only 5 (3%) cases. The majority of cases were successfully defended by surgeons (98 [60%] vs 65 [40%]), particularly in craniofacial surgery (risk ratio: 1.54; P = 0.03; 95% CI: 1.03-2.3). Surgeons who successfully defended a case were more likely to benefit from summary judgment (P = 0.005).Conclusions: Malpractice litigation is commonplace in medical practice, and no specialty is spared. Legal outcomes were in favor of plastic surgeons in the majority of cases, particularly those that proceeded to summary judgment. Surgeons can avoid litigation by maintaining detailed office and surgical notes, always obtaining informed consent, adequately following and monitoring patients after surgery, and ensuring compliance by communicating frequently and effectively.

Background: Breast satisfaction in general female populations is relatively unknown and prior research populations do not reflect our community.Objectives: We sought to assess breast satisfaction in a cohort of female participants utilizing the BREAST-Q and determine the impact of participant-related factors.Methods: Females with no history of breast cancer or breast surgery attending gynecology appointments completed preoperative BREAST-Q reconstruction modules and demographic forms in this prospective, single-center, patient-reported outcomes study. We also assessed participant-related factors capable of influencing BREAST-Q scores.Results: Three hundred females were included. Increasing body mass index had significant associations with lower Satisfaction with Breasts and Psychosocial Well-being scores. Increasing age was associated with significantly lower Sexual Well-being scores. African Americans had significantly higher scores for Satisfaction with Breasts, Psychosocial Well-being, and Sexual Well-being compared with Caucasians. Bra cup sizes A and C were associated with significantly higher Psychosocial Well-being scores than other sizes. Bra cup sizes A, B, and C were associated with significantly higher Sexual Well-being and Physical Well-being: Chest scores than larger sizes. Bra cup sizes B and C were associated with significantly higher Physical Well-being: Abdomen scores than size DD. Bra cup size A was associated with significantly higher Satisfaction with Breasts scores than sizes DD and >DD. Bra cup size C was associated with significantly higher Satisfaction with Breasts scores than larger sizes.Conclusions: Body mass index, age, race, and bra cup sizes significantly impact BREAST-Q scores in our population. Determining normative BREAST-Q scores in female populations could represent important baselines for breast outcomes research.Level of Evidence: 2. [ABSTRACT FROM AUTHOR]

Background  As deep inferior epigastric artery perforator (DIEP) flaps have gained popularity in breast reconstruction, the postoperative care of these patients, including the appropriate hospital length-of-stay and the need for intensive care unit (ICU) admission, has become a topic of debate. At our institution, we have adopted a pathway that aims for discharge on postoperative day 3, utilizing continuous tissue oximetry without ICU admission. This study aims to evaluate outcomes with this pathway to assess its safety and feasibility in clinical practice. Methods  A retrospective review was performed of patients undergoing DIEP flap breast reconstruction between January 2013 and August 2014. Data of interest included patient demographics and medical history as well as complication rates and date of hospital discharge. Results  In total, 153 patients were identified undergoing 239 DIEP flaps. The mean age was 50 years (standard deviation [SD] = 10.2) and body mass index (BMI) 29.4 kg/m 2 (SD = 5.2). Over the study period, the flap failure rate was 1.3% and reoperation rate 3.9%. Seventy-one percent of patients were discharged on postoperative day 3. Nine patients required hospitalization beyond 5 days. Theoretical cost savings from avoiding ICU admissions were $1,053 per patient. Conclusion  A pathway aiming for hospital discharge on postoperative day 3 without ICU admission following DIEP flap breast reconstruction can be feasibly implemented with an acceptable reoperation and flap failure rate.

Elucidating the foreign body response: Synthetic materials are the building blocks for medical devices and implants but can induce a foreign body response after implantation, resulting in fibrous scar tissue encompassing the implant. Here, Chung et al. define the role of interleukin 17 (IL17) and cellular senescence in driving the foreign body response. The fibrous capsule from excised breast implants contained IL17-producing T cells and senescent stromal cells. These findings were further validated in a murine model, and the authors found that blocking the IL17 pathway or eliminating senescent cells mitigated local fibrosis around the implant. This study presents new potential therapeutic targets to reduce fibrosis associated with the foreign body response. Medical devices and implants made of synthetic materials can induce an immune-mediated process when implanted in the body called the foreign body response, which results in formation of a fibrous capsule around the implant. To explore the immune and stromal connections underpinning the foreign body response, we analyzed fibrotic capsules surrounding surgically excised human breast implants from 12 individuals. We found increased numbers of interleukin 17 (IL17)–producing γδ+ T cells and CD4+ T helper 17 (TH17) cells as well as senescent stromal cells in the fibrotic capsules. Further analysis in a murine model demonstrated an early innate IL17 response to implanted synthetic material (polycaprolactone) particles that was mediated by innate lymphoid cells and γδ+ T cells. This was followed by a chronic adaptive CD4+ TH17 cell response that was antigen dependent. Synthetic materials with varying chemical and physical properties implanted either in injured muscle or subcutaneously induced similar IL17 responses in mice. Mice deficient in IL17 signaling established that IL17 was required for the fibrotic response to implanted synthetic materials and the development of p16INK4a senescent cells. IL6 produced by senescent cells was sufficient for the induction of IL17 expression in T cells. Treatment with a senolytic agent (navitoclax) that killed senescent cells reduced IL17 expression and fibrosis in the mouse implant model. Discovery of a feed-forward loop between the TH17 immune response and the senescence response to implanted synthetic materials introduces new targets for therapeutic intervention in the foreign body response.

Introduction: Medicaid beneficiaries are a generally disadvantaged population with access to elective specialty services. We sought to better understand utilization of breast reconstruction by Medicaid beneficiaries. Methods: We systematically searched PubMed, Scopus, Web of Science, and CINAHL databases for studies comparing breast reconstruction rates by insurance type. We extracted the information of interest to qualitatively and quantitatively synthesize the results of the studies. Results: We identified seven eligible studies. Overall, the rates of breast reconstruction have increased across insurance groups. However, our results show that Medicaid beneficiaries were on average less likely to receive breast reconstruction in comparison to patients with private insurance. Although, Medicaid patients again were more likely to receive breast reconstruction in comparison to Medicare beneficiaries. Conclusion: There is wide disparity in reconstruction rates by insurance status. However, with continued increase in the adult Medicaid population due to widening eligibility expansion, disparities involving this vulnerable population should be examined for causes and solutions.

The pursuit of the perfect breast has existed for centuries. Today, women seek reconstructive or cosmetic procedures to approach their current ideals. We conducted a literature search for studies relevant to physical markers of esthetically pleasing breasts and tools to help surgeons achieve these results. Various studies created parameters to define the ideal breast, such as specific proportions, while others suggest that attitudes will fluctuate based on culture and experience. Clinicians should be aware of potential parameters that define the ideal breast and that preference can be influenced by demographics. [ABSTRACT FROM AUTHOR]

Breast sarcomas constitute a rare and heterogeneous group of tumors. Given their aggressive nature and the potential for extensive resections, rates of reconstruction have been low. We retrospectively reviewed subjects derived from our institutional registry presented between 2003 and 2015. Thirty‐four patients with primary breast sarcoma were identified. The average age was 51.9 years and the average follow‐up was 58 months. The most common histological type was malignant phyllodes (61.8%). Two patients suffered cancer recurrence. Twelve patients (35.3%) underwent reconstruction. Four underwent implant‐based reconstruction, seven had autologous‐based reconstruction, and one had combined reconstruction. Major complications were one flap loss and one implant removal. Our relatively high rates of breast reconstruction suggest a newly increased willingness to offer reconstruction to this rarer patient population. [ABSTRACT FROM AUTHOR]

Background: Antibiotic irrigation is routinely used during implant insertion in augmentation mammoplasty procedures. However, the evidence for whether this reduces the incidence of infection or capsular contracture is unclear.Methods and Materials: Five databases were used to search for all randomized control trials, retrospective cohort and prospective cohort studies containing original data related to the primary outcomes being investigated in this study. The primary outcomes were the effects of antibiotic breast pocket irrigation on clinical infection and capsular contracture. The literature search was designed to combine three concepts: implant or tissue expander-based breast surgery, antibiotic irrigation and clinical infection or capsular contracture. Studies found were screened using specific eligibility criteria. Risk ratios (RR) and 95% confidence interval (CI) were calculated using pooled acquired data from all included studies.Results: The search identified 1256 citations. Three independent screeners identified seven studies that met the inclusion criteria with a pooled population of 4725. This included one prospective and six retrospective studies. A meta-analysis of pooled study data showed significant reductions in clinical infection (RR 0.52, 95% CI 0.33-0.81) and capsular contracture (RR 0.36, 95% CI 0.16-0.83) as a result of antibiotic irrigation.Conclusion: The meta-analyses support the use of antibiotic irrigation of the breast pocket. However, the results of this study are limited by the large proportion of retrospective studies, the small number of studies included, the lack of randomized controlled trials and the heterogeneity of the antibiotic and control regimes used.Level of Evidence III: This journal requires that authors assign a level of evidence to each article.

The development of cystic fibrosis transmembrane conductance regulator (CFTR) targeted therapy for cystic fibrosis has generated interest in maximizing membrane residence of mutant forms of CFTR by manipulating interactions with scaffold proteins, such as sodium/hydrogen exchange regulatory factor-1 (NHERF1). In this study, we explored whether COOH-terminal sequences in CFTR beyond the PDZ-binding motif influence its interaction with NHERF1. NHERF1 displayed minimal self-association in blot overlays (NHERF1, Kd = 1,382 ± 61.1 nM) at concentrations well above physiological levels, estimated at 240 nM from RNA-sequencing and 260 nM by liquid chromatography tandem mass spectrometry in sweat gland, a key site of CFTR function in vivo. However, NHERF1 oligomerized at considerably lower concentrations (10 nM) in the presence of the last 111 amino acids of CFTR (20 nM) in blot overlays and cross-linking assays and in coimmunoprecipitations using differently tagged versions of NHERF1. Deletion and alanine mutagenesis revealed that a six-amino acid sequence 1417EENKVR1422 and the terminal 1478TRL1480 (PDZ-binding motif) in the COOH-terminus were essential for the enhanced oligomerization of NHERF1. Full-length CFTR stably expressed in Madin-Darby canine kidney epithelial cells fostered NHERF1 oligomerization that was substantially reduced (∼5-fold) on alanine substitution of EEN, KVR, or EENKVR residues or deletion of the TRL motif. Confocal fluorescent microscopy revealed that the EENKVR and TRL sequences contribute to preferential localization of CFTR to the apical membrane. Together, these results indicate that COOH-terminal sequences mediate enhanced NHERF1 interaction and facilitate the localization of CFTR, a property that could be manipulated to stabilize mutant forms of CFTR at the apical surface to maximize the effect of CFTR-targeted therapeutics.

Objective: To evaluate the impact of magnetic resonance neurography (MRN) on diagnostic thinking and therapeutic choices in patients with suspected peripheral neuropathy.Methods: IRB approval was obtained for this HIPAA-compliant study. Questionnaires were administered to six surgeons regarding the diagnosis and treatment in 85 patients suspected of having peripheral neuropathy, before (pretest) and after (posttest) MRN. Multiple outcome measures related to diagnostic confidence and surgical decision-making were assessed.Results: The final cohort included 81 patients (30 men and 51 women, age 47 ± 17 years). The following changes were observed from pretest to posttest questionnaires: 23% in nerve involvement (P < 0.05), 48% in degree of confidence of nerve involvement (P < 0.01), 27% in grade of injury (P < 0.05), 33% in differential diagnosis (P < 0.05), 63% in degree of confidence in need for surgery (P < 0.001), 41% in timing of surgery (P < 0.01), 30% in approach to surgery (P < 0.05), 58% in degree of confidence in approach to surgery (P < 0.001), 30% in estimated length of surgery (P < 0.05) and 27% in length of incision (P < 0.05). The dichotomous decision regarding surgical or nonsurgical treatment changed from pro to con in 17%.Conclusion: MRN results significantly influenced the diagnostic thinking and therapeutic recommendations of peripheral nerve surgeons.Key Points: • In patients with peripheral neuropathy, MRN significantly impacts diagnostic thinking. • In patients with peripheral neuropathy, MRN significantly impacts therapeutic choices. • 3-T MRN should be considered in presurgical planning of patients with peripheral neuropathy.

Background Worldwide, leprosy represents a significant cause of disability due to progressive neurological impairment. Screening for leprous neuropathy is performed with Semmes-Weinstein monofilament (SWM) or ballpoint pen testing (BPT), which results in underreporting of its prevalence. The Pressure-specified sensory device (PSSD; Sensory Management Services, LLC, Baltimore, MD) is a sensitive, noninvasive, portable, neurosensory instrument, which has not been field-tested for leprosy screening. Early identification of leprous neuropathy would permit early antibiotic treatment to prevent contagion and early microsurgical neurolysis. Methods A prospective, clinical diagnostic, cross-sectional study screened a consecutive sample of patients for leprous neuropathy in the leprosy-endemic province of Los Ríos, Ecuador. Patients meeting the World Health Organization criteria for leprosy and complaining of neuropathy symptoms were classified as leprous neuropathy patients. Patients without any signs of leprosy were used as normal controls. Bilateral ulnar nerve screening with the PSSD, SWM (0.07, 0.4,2,4,10, and 300 g), and BPT was performed in all patients. Sensitivity and specificity were calculated and compared across tests. A total of 71 patients (142 nerves) were evaluated. Results Compared with the 10 g SWM and the BPT, the PSSD was found to have significantly higher sensitivity (78.3 vs. 0% with p < 0.001, for both) with comparable specificity (97.8 vs. 100% with p > 0.999, for both). Compared with the 0.07 g SWM (lightest filament in our series), the PSSD showed better sensitivity (78.3 vs. 65.2%, p = 0.514) and significantly higher specificity (97.8 vs. 51.1%, p < 0.001). Conclusions The PSSD provides superior diagnostic accuracy for detecting leprous neuropathy as compared with SWM and BPT. [ABSTRACT FROM AUTHOR]

ABSTRACT Diagnosis of tibial neuropathy has been traditionally based on clinical examination and electrodiagnostic studies; however, cross-sectional imaging modalities have been used to increase the diagnostic accuracy and provide anatomic mapping of the abnormalities. In this context, magnetic resonance neurography (MRN) offers high-resolution imaging of the tibial nerve (TN), its branches and the adjacent soft tissues, and provides an objective assessment of the neuromuscular anatomy, abnormality, and the surrounding pathology. This review describes the pathologies affecting the TN and illustrates their respective 3 Tesla (T) MRN appearances with relevant case examples. [ABSTRACT FROM AUTHOR]

Objective: Sacrectomy creates a large, complex tissue defect that presents a reconstructive challenge for plastic surgeons. Several myocutaneous flaps have been described for reconstruction following sacral tumor extirpation; however, current publications focus on the reconstructive options applicable to adults.We present amethod of reconstruction following sacral tumor extirpation in a pediatric patient. Methods: The patient was 22 months old and in need of complex closure following low sacral amputation (S3-S4 osteotomy) and en bloc resection of a yolk sac tumor. Following tumor extirpation, the patient was left with a complex defect including extensive dead space, multiple exposed nerve roots, projection of the rectum into the wound, and inadequate soft tissue for primary closure. Results: Reconstruction with human acellular dermal matrix to address the risk of posterior rectal herniation and bilateral gluteal V to Y advancement flaps for obliteration of the dead space allowed for durable closure of the surgical defect. Conclusions: This represents the first case report documenting sacral resection and reconstruction with bilateral V to Y gluteal advancement flaps in a pediatric patient. [ABSTRACT FROM AUTHOR]
