Comparison of mastectomy and breast reconstruction outcomes using low thermal dissection versus traditional electrocautery: a blinded randomized trial.

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.

Perioperative systemic nonsteroidal anti-inflammatory drugs (NSAIDs) in women undergoing breast surgery.

BACKGROUND: Breast surgery encompasses oncologic, reconstructive, and cosmetic procedures. With the recent focus on the over-prescribing of opioids in the literature, it is important to assess the effectiveness and safety of non-opioid pain medication regimens including nonsteroidal anti-inflammatory drugs (NSAIDs) or NSAID pain medications. Clinicians have differing opinions on the safety of perioperative (relating to, occurring in, or being the period around the time of a surgical operation) NSAIDs for breast surgery given the unclear risk/benefit ratio. NSAIDs have been shown to decrease inflammation, pain, and fever, while potentially increasing the risks of bleeding complications. OBJECTIVES: To assess the effects of perioperative NSAID use versus non-NSAID analgesics (other pain medications) in women undergoing any form of breast surgery. SEARCH METHODS: The Cochrane Breast Information Specialist searched the Cochrane Breast Cancer Group (CBCG) Specialized Register, CENTRAL (the Cochrane Library), MEDLINE, Embase, The WHO International Clinical Trials Registry Platform (ICTRP) and Clinicaltrials.gov registries to 21 September 2020. Full articles were retrieved for potentially eligible trials. SELECTION CRITERIA: We considered all randomized controlled trials (RCTs) looking at perioperative NSAID use in women undergoing breast surgery. DATA COLLECTION AND ANALYSIS: Two review authors independently screened studies, extracted data and assessed risk of bias, and certainty of the evidence using the GRADE approach. The main outcomes were incidence of breast hematoma within 90 days (requiring reoperation, interventional drainage, or no treatment) of breast surgery and pain intensity 24 hours following surgery, incidence rate or severity of postoperative nausea, vomiting or both, bleeding from any location within 90 days, need for blood transfusion, other side effects of NSAID use, opioid use within 24 hours of surgery, length of hospital stay, breast cancer recurrence, and non-prescribed NSAID use. Data were presented as risk ratios (RRs) for dichotomous outcomes and standardized mean differences (SMDs) for continuous outcomes. MAIN RESULTS: We included 12 RCTs with a total of 1596 participants. Seven studies compared NSAIDs (ketorolac, diclofenac, flurbiprofen, parecoxib and celecoxib) to placebo. Four studies compared NSAIDs (ketorolac, flurbiprofen, ibuprofen, and celecoxib) to other analgesics (morphine, hydrocodone, hydromorphone, fentanyl). One study compared NSAIDs (diclofenac) to no intervention. NSAIDs compared to placebo Most outcomes are judged to have low-certainty evidence unless stated otherwise. There may be little to no difference in the incidence of breast hematomas within 90 days of breast surgery (RR 0.33, 95% confidence interval (CI) 0.05 to 2.02; 2 studies, 230 participants; I2 = 0%). NSAIDs may reduce pain intensity 24 (± 12) hours following surgery compared to placebo (SMD -0.26, 95% CI -0.49 to -0.03; 3 studies, 310 participants; I2 = 73%). There may be little to no difference in the incidence rates or severities of postoperative nausea, vomiting, or both (RR 1.15, 95% CI 0.58 to 2.27; 4 studies, 939 participants; I2 = 81%), bleeding from any location within 90 days (RR 1.05, 95% CI 0.89 to 1.24; 2 studies, 251 participants; I2 = 8%), or need for blood transfusion compared to placebo groups, but we are very uncertain (RR 4.62, 95% CI 0.23 to 91.34; 1 study, 48 participants; very low-certainty evidence). There may be no difference in other side effects (RR 1.12, 95% CI 0.44 to 2.86; 2 studies, 251 participants; I2 = 0%). NSAIDs may reduce opioid use within 24 hours of surgery compared to placebo (SMD -0.45, 95% CI -0.85 to -0.05; 4 studies, 304 participants; I2 = 63%). NSAIDs compared to other analgesics There is little to no difference in the incidence of breast hematomas within 90 days of breast surgery, but we are very uncertain (RR 0.33, 95% CI 0.01 to 7.99; 1 study, 100 participants; very low-certainty evidence). NSAIDs may reduce pain intensity 24 (± 12) hours following surgery (SMD -0.68, 95% CI -0.97 to -0.39; 3 studies, 200 participants; I2 = 89%; low-certainty evidence) and probably reduce the incidence rates or severities of postoperative nausea, vomiting, or both compared to other analgesics (RR 0.18, 95% CI 0.06 to 0.57; 3 studies, 128 participants; I2 = 0%; moderate-certainty evidence). There is little to no difference in the development of bleeding from any location within 90 days of breast surgery or in other side effects, but we are very uncertain (bleeding: RR 0.33, 95% CI 0.01 to 7.99; 1 study, 100 participants; other side effects: RR 0.11, 95% CI 0.01 to 1.80; 1 study, 48 participants; very low-certainty evidence). NSAIDs may reduce opioid use within 24 hours of surgery compared to other analgesics (SMD -6.87, 95% CI -10.93 to -2.81; 3 studies, 178 participants; I2 = 96%; low-certainty evidence). NSAIDs compared to no intervention There is little to no difference in pain intensity 24 (± 12) hours following surgery compared to no intervention, but we are very uncertain (SMD -0.54, 95% CI -1.09 to 0.00; 1 study, 60 participants; very low-certainty evidence). AUTHORS' CONCLUSIONS: Low-certainty evidence suggests that NSAIDs may reduce postoperative pain, nausea and vomiting, and postoperative opioid use. However, there was very little evidence to indicate whether NSAIDs affect the rate of breast hematoma or bleeding from any location within 90 days of breast surgery, the need for blood transfusion and incidence of other side effects compared to placebo or other analgesics. High-quality large-scale RCTs are required before definitive conclusions can be made.

Integrated Transcriptomic and Proteomic Analysis of Human Eccrine Sweat Glands Identifies Missing and Novel Proteins.

The eccrine sweat gland is an exocrine gland that is involved in the secretion of sweat for control of temperature. Malfunction of the sweat glands can result in disorders such as miliaria, hyperhidrosis and bromhidrosis. Understanding the transcriptome and proteome of sweat glands is important for understanding their physiology and role in diseases. However, no systematic transcriptome or proteome analysis of sweat glands has yet been reported. Here, we isolated eccrine sweat glands from human skin by microdissection and performed RNA-seq and proteome analysis. In total, ∼138,000 transcripts and ∼6,100 proteins were identified. Comparison of the RNA-seq data of eccrine sweat glands to other human tissues revealed the closest resemblance to the cortex region of kidneys. The proteome data showed enrichment of proteins involved in secretion, reabsorption, and wound healing. Importantly, protein level identification of the calcium ion channel TRPV4 suggests the importance of eccrine sweat glands in re-epithelialization of wounds and prevention of dehydration. We also identified 2 previously missing proteins from our analysis. Using a proteogenomic approach, we identified 7 peptides from 5 novel genes, which we validated using synthetic peptides. Most of the novel proteins were from short open reading frames (sORFs) suggesting that many sORFs still remain to be annotated in the human genome. This study presents the first integrated analysis of the transcriptome and proteome of the human eccrine sweat gland and would become a valuable resource for studying sweat glands in physiology and disease.

Tissue Expander-Based Breast Reconstruction in the Prepectoral Versus Subpectoral Plane: An Analysis of Short-Term Outcomes.

BACKGROUND: Breast reconstruction is becoming an increasingly important and accessible component of breast cancer care. We hypothesize that prepectoral patients benefit from lower short-term complications and shorter periods to second-stage reconstruction compared with individuals receiving reconstruction in the subpectoral plane. METHODS: An institutional review board-approved retrospective review of all adult postmastectomy patients receiving tissue expanders (TEs) was completed for a 21-month period (n = 286). RESULTS: A total of 286 patients underwent mastectomy followed by TE placement, with 59.1% receiving prepectoral TEs and 40.9% receiving subpectoral TEs. Participants receiving prepectoral TEs required fewer clinic visits before definitive reconstruction (6.4 vs 8.8, P <0.01) and underwent definitive reconstruction 71.6 days earlier than individuals with subpectoral TE placement (170.8 vs 242.4 days, P < 0.01). Anesthesia time was significantly less for prepectoral TE placement, whether bilateral (68.0 less minutes, P < 0.01) or unilateral (20.7 minutes less, P < 0.01). Operating room charges were higher in the prepectoral subgroup ($31,276.8 vs $22,231.8, P < 0.01). Partial necrosis rates were higher in the prepectoral group (21.7% vs 10.9%, P < 0.01). CONCLUSIONS: Patients undergoing breast reconstruction using prepectoral TE-based reconstruction benefit from less anesthesia time, fewer postoprative clinic visits, and shorter time to definitive reconstruction, at the compromise of higher operating room charges.

Pure fat grafting for breast reconstruction: An alternative autologous breast reconstruction.

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.

Online Patient Resources for Breast Implant-Associated Anaplastic Large Cell Lymphoma: A Readability Analysis.

INTRODUCTION: Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is an emerging issue facing the medical community. Government organizations such as the US Food and Drug Administration and specialty groups including the American Society of Plastic Surgeons have published online resources about BIA-ALCL for patients. Given the complexity of the diagnosis, it is important that patients can easily read these resources. In this study, we examined the readability levels of online BIA-ALCL patient resources using multiple verified reading scores. METHODS: "BIA-ALCL" and "breast implant-associated anaplastic large cell lymphoma" were entered into 3 Internet search engines. The top 20 results for each were filtered by resource type and intended audience (physician vs patient). Published scientific articles, online database physician resources, and Web sites requiring subscriptions or fees were excluded. We then examined the readability of each with multiple verified reading scores, including the Flesch-Kincaid, Gunning-Fog, Coleman-Liau, Simplified Measure of Gobbledygook, and Automated Readability Index indices. Obtained data were analyzed using descriptive statistics and t test for independent samples. RESULTS: Fifteen Web sites qualified for further analysis. For all texts, the average readability level was measured between 12 and 13 years of education on each readability index or approximately 18 to 19 years old. The Flesch-Kincaid Reading Ease average was 43.16 ±10.9 on a scale of 1 to 100, corresponding to a "difficult" designation. When compared by search criteria (spelled-out vs abbreviated), the results for the abbreviation "BIA-ALCL" had higher education requirements than those with the condition spelled out. However, these differences were not statistically significant. There was also great variation in word and sentence measurements. Twelve of the 15 Web sites contained more than 15% complex words, having more than 3 syllables, with breastcancer.org having the lowest (11%) and plasticsurgery.org the highest (20%). DISCUSSION: Since the initial announcement in 2014 by the National Cancer Comprehensive Network, the medical community has begun educating ourselves and our patients about BIA-ALCL. Unfortunately, this study suggests that online patient resources on BIA-ALCL may be too complex for most readers, exceeding that of the average US resident (eighth grade) and Medicare beneficiary (fifth grade). Although the goal of learning more about BIA-ALCL and counseling patients appropriately remains paramount, we should continue to improve patient education materials given their vital role in healthcare decision-making.

Comparison of arterial and venous implantable Doppler postoperative monitoring of free flaps: Systematic review and meta-analysis of diagnostic test accuracy.

BACKGROUND: Early detection of vascular compromise following free flap microsurgical reconstruction is essential. This can lead to timely reoperations and flap salvage. Both arteries and veins are monitored postoperatively with implantable ultrasound Dopplers based on surgeon preference with no consensus as to which method is best. This systematic review and meta-analysis compared arterial to venous implantable Dopplers for postoperative monitoring of microsurgical free flap reconstruction. METHODS: Five databases (MEDLINE via PubMed, EMBASE, Cochrane Library, Web of Science, and Scopus) were systematically and independently searched. PRISMA and Cochrane guidelines were strictly followed. Clinical characteristics, donor and recipient sites, specific arterial or venous vessels, diagnostic data, outcomes, and complications were recorded. RESULTS: The seven studies included in the meta-analysis were published from 1994 to 2018, with results from 38 of the possible 64 outcomes and complications queried. A total of 763 flaps with implantable Doppler probes on 527 arteries and 388 veins were included in the study. Compared to patients monitored with venous implantable Dopplers, arterial monitoring was associated with a risk of false-positives reduced by 74% (RR:0.26, 95% CI:0.12, 0.55, I2 = 40%, p = .0004) and risk of signal loss reduced by 63% (RR:0.37, 95% CI:0.24, 0.59, I2 = 26%, p < .0001). Patients being monitored with a venous implantable Doppler did not show significantly different sensitivities, specificities, true-positives, false-negatives, true-negatives, positive predictive values, negative predictive values, time to signal loss, take-backs, salvage rates, flap failures, flap failure rates, arterial, venous, vascular, and hematoma compromise compared to an arterial implantable Doppler. CONCLUSION: These findings suggest arteries may be the best vessels to monitor when using an implantable Doppler following free flap microsurgical reconstruction. Caution is advised when interpreting these findings for clinical significance due to no significant differences in take-backs, SR, flap failures, and FFR.

Postoperative Free Flap Breast Protocol Optimizing Resources and Patient Safety.

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/m2 (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.

Breast Reduction in Adults: Identifying Risk Factors for Overall 30-Day Postoperative Complications.

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.

Malpractice Litigation in Plastic Surgery: Can We Identify Patterns?

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.

Establishing Institution-Specific Normative Data for the BREAST-Q Reconstruction Module: A Prospective Study.

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.

Classification of breast tissue expander infections: Back to the basics.

BACKGROUND: Infections following tissue expander (TE) placement are frequent complications in breast reconstruction. While breast surgery is a clean case, implant-based breast reconstruction has rates of infection up to 31%, decidedly higher than the typical 1% to 2% rate of surgical site infections (SSI). Few authors use the Center for Disease Control's (CDC) SSI definition for TE infections. We highlight how adoption of a consistent definition of TE infection may change how infections are researched, categorized, and ultimately managed. METHODS: Two researchers with definitional discrepancies of infection performed an independent analysis of all postmastectomy patients receiving TEs (n = 175) in 2017. RESULTS: Researcher One, using a clinical definition, delineated an infection rate of 19.4%. Antibiotics alone successfully treated 50% of cases. Researcher Two found an infection rate of 13.7% using CDC criteria. These infections were further delineated by a SSI rate of 6.3% and a TE infection rate post port access of 7.4%. Only 45.5% SSI's and 15.4% of TE infections were salvaged with antibiotics alone. CONCLUSIONS: Rigorous adoption of CDC criteria for infection characterization in published research will help standardize the definition of infection and allow surgeons to create evidence-based infection prevention regimens.

The notion of the ideal breast and its variability: Reviewing the difficulty of perceiving beauty through defined margins.

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.

Reconstruction options and outcomes for breast sarcoma patients.

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.

The Role of Antifibrinolytics in Reducing Blood Loss During Craniofacial or Orthognathic Surgical Procedures: A Meta-Analysis.

PURPOSE: Use of antifibrinolytic drugs in craniofacial and orthognathic surgery seems quite promising and has strong advocates. However, supporting evidence is controversial and limited by a small sample of individual studies. We sought to systematically review and meta-analyze the available data regarding the role of preoperative or intraoperative antifibrinolytic drugs (eg, tranexamic acid, aprotinin, or aminocaproic acid) in craniofacial and orthognathic surgery. MATERIALS AND METHODS: We searched PubMed, Scopus, Embase, the Cochrane Library, and Web of Science through April 19, 2018, according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Outcomes of interest included the volume of blood loss, volume of transfusions, and operative time. A meta-analysis was performed with a random-effects model using Review Manager (RevMan) software (The Cochrane Collaboration, Copenhagen, Denmark). RESULTS: We identified 32 eligible studies with 749 patients undergoing craniofacial surgery and 546 undergoing orthognathic surgery. Meta-analysis showed that antifibrinolytic use led to statistically significant decreases in blood loss and blood transfusions for craniofacial procedures in adult or pediatric patients and to significantly less blood loss during orthognathic surgical procedures. Operative time did not significantly differ for either type of surgery. CONCLUSIONS: Antifibrinolytics can significantly reduce blood loss in craniofacial surgical procedures including pediatric craniosynostosis and adult rhinoplasties and in orthognathic surgical procedures, as well as transfusion requirements in pediatric craniofacial surgical procedures. However, the clinical significance of the medications is still questionable because of the relative paucity of information on adverse effects and the usual small volume loss during those operations.

Origins of Gender Affirmation Surgery: The History of the First Gender Identity Clinic in the United States at Johns Hopkins.

BACKGROUND: Gender-affirming care, including surgery, has gained more attention recently as third-party payers increasingly recognize that care to address gender dysphoria is medically necessary. As more patients are covered by insurance, they become able to access care, and transgender cultural competence is becoming recognized as a consideration for health care providers. A growing number of academic medical institutions are beginning to offer focused gender-affirming medical and surgical care. In 2017, Johns Hopkins Medicine launched its new Center for Transgender Health. In this context, history and its lessons are important to consider. We sought to evaluate the operation of the first multidisciplinary Gender Identity Clinic in the United States at the Johns Hopkins Hospital, which helped pioneer what was then called "sex reassignment surgery." METHODS: We evaluated the records of the medical archives of the Johns Hopkins University. RESULTS: We report data on the beginning, aim, process, outcomes of the clinic, and the reasons behind its closure. This work reveals the function of, and the successes and challenges faced by, this pioneering clinic based on the official records of the hospital and mail correspondence among the founders of the clinic. CONCLUSION: This is the first study that highlights the role of the Gender Identity Clinic in establishing gender affirmation surgery and reveals the reasons of its closure.

Keloid Excision and Adjuvant Treatments: A Network Meta-analysis.

BACKGROUND: Keloid disease treatment continues to be unsatisfactory with high recurrence rates. We evaluated the literature regarding the effectiveness of keloid excision with various adjuvant treatments following surgery and assessed recurrence rates. METHODS: We systematically searched databases through November 2016. We performed pairwise meta-analyses and Bayesian network meta-analyses on the number of recurrences. RESULTS: Following screening, 14 studies including 996 patients with various types of keloids were eligible for inclusion. Patients were categorized based on the receipt of surgery and the type of adjuvant treatment employed afterward. Paired meta-analysis (6 meta-analyses) showed that "excision + 1 adjuvant drug" led to statistically significantly higher odds of recurrence compared to "excision + radiation" (odds ratio [OR], 3.22; 95% confidence interval [CI], 1.35-7.67). Based on the network meta-analyses, the ORs of keloid recurrence following various treatments compared to no excision were as follows: "excision + pressure, 0.18 (95% CI, 0.01-7.07); excision + 2 adjuvants drugs, 0.47 (95% CI, 0.02-12.82); excision + radiation, 0.39 (95% CI, 0.04-3.31); excision + skin grafting, 0.58 (95% CI, 0.00-76.10); excision + 1 adjuvant drug, 1.76 (95% CI, 0.17-21.35); and excision only, 2.17 (95% CI, 0.23-23.95). CONCLUSIONS: According to our results, "excision + radiation" had significantly better outcomes than excision alone. "Excision + pressure" had better outcomes than excision + any other treatment modality, and excision + nonradiation adjuvant therapies were also better than "excision only," although these findings did not reach statistical significance.

Delayed Breast Reconstruction on Patients With Upper Extremity Lymphedema: A Systematic Review of the Literature and Pooled Analysis.

BACKGROUND: Breast cancer-related lymphedema (BCRL) is a debilitating condition with morbidity, hindered quality of life, and increased health-related costs. Experimental studies support the use of musculocutaneous flaps for managing animal models with lymphedema. Although vascularized lymph node transfer (VLNT) and lymphovenous anastomosis are used to surgically treat patients with lymphedema, it is not known whether musculocutaneous or adipocutaneous flaps (eg, delayed autologous breast reconstruction) are effective for treating refractory upper extremity BCRL. We conducted a systematic review and pooled analysis to assess the impact of delayed breast reconstruction on developed BCRL. METHODS: Following PRISMA guidelines, we systematically searched PubMed, Scopus, EMBASE, and Google Scholar databases for relevant studies published through November 11, 2016. We screened 934 unique articles. Of these, we conducted full-text and reference screening on 37 articles. We then performed a pooled and sensitivity analysis using random effects. RESULTS: Eight studies met our inclusion criteria. One study was a case report; 7 studies were case series with sample sizes ranging from 3 to 38 patients. According to our pooled analysis 58% of patients reported improvement after breast reconstruction with or without VLNT. Sensitivity analysis revealed that 84% (95% confidence interval, 0.74-0.95) of patients who underwent breast reconstruction and VLNT reported improvement, whereas only 22% (95% confidence interval, 0.12-0.32) of those who had breast reconstruction alone reported improvement. CONCLUSIONS: Our review summarizes the current evidence regarding the effect of delayed breast reconstruction on established lymphedema. The VLNT component of the autologous breast reconstruction procedures may be the largest contributing factor leading to lymphedema improvement.

Breast Pocket Irrigation with Antibiotic Solution at Implant Insertion: A Systematic Review and Meta-Analysis.

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.

Diagnostic Accuracy of Selective 3-T MR Neurography-guided Retroperitoneal Genitofemoral Nerve Blocks for the Diagnosis of Genitofemoral Neuralgia.

Purpose To determine if 3-T magnetic resonance (MR) neurography-guided retroperitoneal genitofemoral nerve (GFN) blocks are safe and effective for the diagnosis of genitofemoral neuralgia. Materials and Methods Following institutional review board approval and informed consent, 26 subjects (16 men, 10 women; mean age, 42 years [range, 24-78 years]; mean body mass index, 28 kg/m2 [range, 20-35 kg/m2]) with intractable groin pain were included. By using a 3-T MR imaging system, intermediate-weighted turbo spin-echo pulse sequences, and MR-conditional needles, diagnostic MR neurography-guided GFN blocks were performed in the retroperitoneum. Outcome variables included technical success, procedure time, complications, and rates of positive and negative GFN blocks in association with therapeutic outcomes. For the assessment of a learning curve, Mann-Whitney test was used. P values ≤ .05 were considered to indicate a statistically significant difference. Results In 26 subjects, 30 retroperitoneal GFN blocks were performed. Twelve (40%) were performed with an anterior needle path, 12 (40%) with a lateral needle path, and six (20%) with a posterior needle path. GFN blocks were technically successful in 24 of 26 (92%) subjects, achieving appropriate scrotal anesthesia. No complications occurred. The time required for a GFN block was 40 minutes (range, 18-67 minutes). The rate of a successful GFN intervention after a positive GFN block was 88% (14 of 16). The rate of a successful intervention of an alternative target after a negative GFN block was 71% (five of seven). Conclusion Selective retroperitoneally directed MR neurography-guided GFN blocks are safe and effective with high technical success and positive effect on surgical decision making in patients with presumed genitofemoral neuralgia. © RSNA, 2017 Online supplemental material is available for this article.
