RESUMO

Staged nipple-sparing mastectomy (NSM) following mastopexy or breast reduction has become increasingly utilized in patients with large or ptotic breasts. The safety and efficacy of this approach has been demonstrated in recent years. However, the optimal timing between stages has not been established. The authors provide their experience with this staged approach with emphasis on timing between stages. An institutional review board approved this retrospective study. Data of all patients at a single institution who underwent staged NSM following mastopexy or reduction mammaplasty for therapeutic or prophylactic oncologic surgical management from 2016 to 2020 were reviewed. Timing between stages as well as surgical, oncologic, aesthetic, and patient-reported outcomes were evaluated. Nineteen patients (38 breasts) underwent staged NSM following planned mastopexy/breast reduction. The mean time interval between stages was 25 weeks. No patients developed nipple areolar complex necrosis. Infection and hematoma were seen in one breast (2.6%) and seroma in two (5.3%) after NSM. Delayed wound healing was seen in eight breasts (21.1%) after first stage mastopexy/reduction and in 12 breasts (31.6%) after NSM. Skin flap necrosis was noted in two breasts (5.3%) after NSM. No patients developed oncological recurrence. Mean patient-reported post-operative satisfaction and well-being scores were 63 and 67 out of 100, respectively. The authors describe their experience with staged NSM following nipple repositioning procedures. Their results suggest that this procedure can be performed safely with cosmetically favorable results if surgeons wait an average of 25 weeks between first and second stage procedures.

RESUMO

CD4+Foxp3+ regulatory T cells (Tregs) play an essential role in suppressing transplant rejection, but their role within the graft and heterogeneity in tolerance are poorly understood. Here, we compared phenotypic and transcriptomic characteristics of Treg populations within lymphoid organs and grafts in an islet xenotransplant model of tolerance. We showed Tregs were essential for tolerance induction and maintenance. Tregs demonstrated heterogeneity within the graft and lymphoid organs of tolerant mice. A subpopulation of CD127hi Tregs with memory features were found in lymphoid organs, presented in high proportions within long-surviving islet grafts, and had a transcriptomic and phenotypic profile similar to tissue Tregs. Importantly, these memory-like CD127hi Tregs were better able to prevent rejection by effector T cells, after adoptive transfer into secondary Rag-/- hosts, than naive Tregs or unselected Tregs from tolerant mice. Administration of IL-7 to the CD127hi Treg subset was associated with a strong activation of phosphorylation of STAT5. We proposed that memory-like CD127hi Tregs developed within the draining lymph node and underwent further genetic reprogramming within the graft toward a phenotype that had shared characteristics with other tissue or tumor Tregs. These findings suggested that engineering Tregs with these characteristics either in vivo or for adoptive transfer could enhance transplant tolerance.

RESUMO

INTRODUCTION: Effective pain management is crucial in cleft lip and palate (CLP) patients undergoing orthognathic surgery for earlier recovery and decreased opioid reliance. Liposomal bupivacaine (Exparel) is a local anesthetic that provides extended postoperative analgesia in adult patients; however, research on its use in adolescents is limited. This study explores the efficacy of liposomal bupivacaine for postoperative pain management in adolescent CLP patients undergoing orthognathic surgery. METHODS: The authors performed a retrospective chart review at their institution between July 2020 and December 2022 to identify patients who underwent LeFort I or mandibular osteotomy. Two cohorts were compared: patients who received liposomal bupivacaine and patients who received standard pain medications alone. Outcome measures included intraoperative pain medications, length of stay, breakthrough opioid use, time to first oral intake, volume of oral intake, and opioids prescribed at discharge. RESULTS: This study included 22 patients who underwent orthognathic surgery. The liposomal bupivacaine group (n=10) demonstrated earlier and greater oral intake during hospitalization compared with controls (n=12). The most significant difference was observed in total breakthrough opioid use, with an average of 8.60 morphine milligram equivalents for liposomal bupivacaine patients compared with 35.1 morphine milligram equivalents for controls (P=0.037). CONCLUSIONS: This study provides the first analysis of liposomal bupivacaine use in adolescent CLP patients undergoing orthognathic surgery, demonstrating a significant reduction in postoperative opioid consumption compared with controls. These results may guide future studies of liposomal bupivacaine within CLP patients, potentially as a component of enhanced recovery after surgery guidelines, as well as in cost-analysis studies.

RESUMO

BACKGROUND CONTEXT: Since 2015, plastic multilayer closure (PMC) has been gaining attraction due to improved wound healing outcomes for medically complex patients. Plastic multilayer closure has been readily used for complex spine surgery closures in patients susceptible to wound healing issues (ie, dehiscence, surgical site infection [SSI]). However, PMC requires extensive soft tissue manipulation compared with standard orthopedic spine surgeon closure (SOC) and can result in extended operative times, increased transfusion rates, and more frequent returns to the operating room. PURPOSE: From 2016 to 2019, our institution implemented a perioperative protocol designed to decrease postoperative complication rates in NMS patients. A retrospective cohort study was performed to determine if PMC imparted advantages over SOC above and beyond that from the perioperative protocol. STUDY DESIGN/SETTING: Retrospective study at a single academic institution. PATIENT SAMPLE: Eighty-one pediatric patients with neuromuscular scoliosis undergoing spinal fixation surgery. OUTCOME MEASURES: Postoperative wound complications such as surgical site infection, hematoma, and superficial/deep dehiscence were the main outcome measures. Respiratory and neuromuscular complications along with duration of surgery were also recorded. METHODS: A retrospective review was conducted of NMS patients undergoing spinal fixation at a single academic pediatric hospital over 4 years. Cases were labeled as SOC (n=41) or PMC (n=40) based on the closure technique applied. Reported 90-day complications were evaluated as the primary outcome. RESULTS: Of the 81 reviewed patients, 45 reported complications, roughly equal between the study groups. While we found no statistically significant differences in rates of postoperative complications or SSIs, SOC cases were 30 minutes shorter on average with fewer returns to the operating room for additional surgery. CONCLUSIONS: With the implementation of our perioperative protocol for NMS patients, PMC did not result in fewer complications than SOC but the surgeries did take longer.

RESUMO

Advancements in microsurgery, along with increased microsurgical experience in pediatric patients, have made free-tissue transfer a reliable modality for pediatric bone and soft tissue reconstruction today. Free-tissue transfer is most commonly used in children for the coverage of large or complex defects resulting from traumatic, oncologic, or congenital etiologies. While flap success and complication rates between pediatric and adult populations are similar, special considerations must be taken into account within the pediatric population. In this article, we will describe common indications, technical nuances, and clinical considerations for the management of the pediatric free-tissue transfer patient.

RESUMO

Congenital ear anomalies affect 15 to 20% of neonates and can be categorized as either auricular deformations or malformations. Deformations involve a fully developed, albeit abnormally shaped, chondrocutaneous framework, which makes them amenable to correction with ear molding within the first few months of life. Malformations involve hypoplastic or fully absent auricular structures that require augmentation with alloplastic and/or autogenous reconstruction. The goal of this article is to outline the various auricular deformities and malformations, followed by a description of the latest clinical management options, both nonsurgical and surgical, by auricular anomaly.

RESUMO

Distraction osteogenesis (DO) of the craniofacial skeleton has become an effective technique for the treatment of both nonsyndromic and syndromic conditions. The advent of craniofacial DO has allowed for earlier intervention in pediatric patients with less complication risk and morbidity compared to traditional techniques. In this review, we will discuss current application and technique for craniofacial DO by anatomical region and explore future applications in craniofacial surgery.

RESUMO

ABSTRACT: The authors present a review of the literature regarding pressure injuries (PIs) in neonates and a case of a newborn who developed a PI following a prolonged labor process and fetal malposition. A girl born at 35 weeks' gestation to a 34-year-old gravida 7 para 6 mother with a medical history of untreated gestational diabetes, preeclampsia, and COVID-19 was delivered via cesarean section after failure to progress through labor. The premature infant was found to have a 3.2 × 2.3-cm PI at the nape of the posterior neck. Premature infants have a histologically proven, age-dependent decreased thickness of their stratum corneum, epidermis, and dermis, which places them at increased risk of developing PIs that can be painful and lead to infection. In the present case, the neonate's congenital PI was successfully treated with medical-grade honey for approximately a month.

RESUMO

BACKGROUND: Measurements of postoperative velopharyngeal dysfunction (VPD) can be used to determine the efficacy of a palatoplasty operation. Hypernasality and audible nasal air emission are typical manifestations of VPD during speech. We aimed to longitudinally compare VPD outcomes in postpalatoplasty patients who underwent Furlow repair versus straight line repair with intravelar veloplasty (IVVP). Additionally, we examined the relationship between VPD outcomes and select pre-existing patient characteristics. METHODS: Retrospective chart review was performed to identify primary palatoplasty patients treated from April 2012 to March 2021. Variables collected included gender, syndromic status, primary language, Veau cleft type, type of speech assessment, age at time of surgery, degree of hypernasality, presence of audible nasal air emission, and overall adequacy of velopharyngeal function. Pearson χ2 test and multivariable t tests were used to analyze variables. Logistic regression was used to control for statistically significant variables. RESULTS: Of the 118 patients included, 38 received a Furlow procedure and 80 received a straight line with IVVP procedure. Audible nasal air emission was present in 57.3% of straight line with IVVP patients and 42.9% of Furlow patients, with no statistically significant difference between groups. Clinically significant hypernasality was present in 42.1% of straight line with IVVP patients and 22.9% of Furlow patients (P=0.05). Velopharyngeal function was classified as adequate in 63.5% of straight line with IVVP patients and 83.3% of Furlow patients (P=0.03). However, after stratifying by syndromic versus nonsyndromic status, there was no statistically significant difference between straight line with IVVP and Furlow patients for postoperative hypernasality and velopharyngeal function. CONCLUSIONS: This study suggests that there are no statistically significant differences between straight line with IVVP and Furlow palatoplasty techniques regarding speech outcomes including hypernasality, audible nasal air emission, and overall VP function. Furthermore, select patient characteristics such as gender, primary language, syndromic status, age at repair, and Veau cleft type do not significantly impact postoperative speech outcomes.

RESUMO

Minimally invasive approaches to breast surgery have evolved from endoscopic techniques to recent developments in robotic-assisted mastectomies. Initial studies on robotic-assisted nipple-sparing mastectomy (RNSM) have shown improved patient satisfaction and aesthetic outcomes with similar complication rates and oncological outcomes in selected patients. This chapter reviews techniques used and available data on complications and clinical outcomes for RNSM. Currently, RNSM is an investigational technique in the United States and should be performed in clinical trials with U.S. Food & Drug Administration approval to rigorously evaluate the safety and effectiveness of this approach.

RESUMO

Microsurgery has changed the ability to perform highly precise and technical surgeries through the utilization of high-powered microscopes and specialized instruments to manipulate and repair anatomical structures as small as a few millimeters. Since the first human trials of robotic-assisted microsurgery in 2006, the expansion of microsurgery to supermicrosurgery (luminal diameter less than 1 mm) has enabled successful repair of previously inaccessible structures. Surgical robotic systems can offer two distinct operative advantages: (1) minimal access surgery-by entering body cavities through ports, flap harvest can be redesigned to affect a minimally invasive approach for flaps such as the rectus abdominis muscle, the latissimus flap, and the deep inferior epigastric perforator flap; and (2) precision-by eliminating physiologic tremor, improving ergonomics, increasing accessibility to difficult spaces, and providing motion scaling, precision is significantly enhanced. Robotic-assisted microsurgery is a promising application of robotics for the plastic surgeon and has played an important role in flap harvest, head and neck reconstruction, nerve reconstruction, gender-affirming surgery, and lymphatic reconstruction-all the while minimizing surgical morbidity. This article aims to review the history, technology, and application of microsurgery and supermicrosurgery in plastic surgery.

RESUMO

Over the past two decades, the surgical community has increasingly embraced robotic-assisted surgery (RAS) due to its potential to enhance accuracy and decrease surgical morbidity. Plastic surgery as a field has been historically slow to incorporate RAS, with lack of adequate training posing as one of the most commonly cited barriers. To date, robot technology has been utilized for various reconstructive procedures including flap elevation and inset, pedicle dissection, and microvascular anastomosis. As RAS continues to integrate within plastic surgery procedures, the need for a structured RAS curriculum designed for plastic surgery trainees is rising. This article delineates the essential components of a plastic surgery-specific RAS curriculum and outlines current training models and assessment tools utilized across surgical subspecialties to date.

RESUMO

Introduction: Currently, no group specifically supports and coordinates primary care focused cancer research in Ireland. The aim of this project is to establish an inclusive stakeholder group for primary care focused cancer research in Ireland, to coordinate research efforts and build capacity in researchers and institutions. Methods: We will convene a stakeholder group, recruiting individuals with personal and professional experience of cancer care in a community setting. "Core stakeholders"-patients, clinicians, researchers, and policymakers-will attend regularly. Additional "specialist stakeholders", such as representatives of secondary care, private healthcare, health insurance, industry, cancer charities, and health research funders, will participate on an ad hoc basis. An e-Delphi consensus process will be used to assess the stakeholders' views on: (1) the relevance and importance of primary care focused cancer research; (2) the potential role and scope of the stakeholder group; (3) how best to engage with lived experience stakeholders and healthcare professionals affected by the research; (4) how to encourage the dissemination of results and the translation of findings into practice. Round 1 will be open-ended and will invite the independent suggestions of stakeholders; in Round 2 and 3, group members will vote on the inclusion of these suggestions in a position statement by the group, with consensus defined as ≥75% agreement. Discussion: The formation of a broad stakeholder group to support primary care focused cancer research will ensure research is relevant, patient centered, and more readily translated into practice. It is also hoped that the group will support capacity building and strategic planning in this important research space.

RESUMO

BACKGROUND: The cancellation of clinical rotations (CRs) and implementation of virtual interviews (VIs) profoundly affected the residency selection process leading up to the 2021 NRMP Match. The authors investigated how these changes influenced the caliber of applicants taken by general surgery (GS) residency programs from the perspectives of program directors (PDs). METHODS: A 14 question, web-based electronic survey was emailed to PDs of ACGME-accredited GS residency programs. Questions sought program characteristics and PDs' perspectives regarding potential differences in subjective characteristics and clinical skills demonstrated by their 2021 Match class relative to previous resident classes. RESULTS: A total of 75 PDs (27.2%) responded to our survey. Most respondents observed no changes in residents' fit with their program (72.0%), communication skills (68.0%), responsiveness to clinical instruction and feedback (73.3%), work ethic (73.3%), and rotation evaluations (68.0%). Only 21.3% of PDs believed that VIs negatively impacted their ability to accurately assess applicant intangibles. Conversely, 56.0% of PDs reported that the cancellation of CRs in 2020 negatively affected residents' clinical competency at the start of residency. At 1-year following the 2021 NRMP Match, 30.7% of PDs reported that the clinical skills exhibited by their 2021 Match class were poorer than previous resident classes. DISCUSSION: Our findings suggest that VIs limited selection committees' ability to accurately assess applicant's subjective characteristics to a lesser degree than previously described in the literature. Canceled CRs adversely affected the 2021 Match Class's clinical skills at the start of residency and at 1 year following the 2021 NRMP Match.

RESUMO

Patients with lung cancer (LC) often experience delay between symptom onset and treatment. Primary healthcare professionals (HCPs) can help facilitate early diagnosis of LC through recognising early signs and symptoms and making appropriate referrals. This systematic review describes the effect of interventions aimed at helping HCPs recognise and refer individuals with symptoms suggestive of LC. Seven studies were synthesised narratively. Outcomes were categorised into: Diagnostic intervals; referral and diagnosis patterns; stage distribution at diagnosis; and time interval from diagnosis to treatment. Rapid access pathways and continuing medical education for general practitioners can help reduce LC diagnostic and treatment delay. Awareness campaigns and HCP education can help inform primary HCPs about referral pathways. However, campaigns did not significantly impact LC referral rates or reduce diagnostic intervals. Disease outcomes, such as LC stage at diagnosis, recurrence, and survival were seldom measured. Review findings highlight the need for longitudinal, powered, and controlled studies.

RESUMO

As COVID-19 vaccination for children becomes commonplace in Ireland, it is important to understand parent's willingness to vaccinate their children and factors associated with hesitancy and resistance. Amongst a nationally representative sample of parents from Ireland, surveyed in March/April 2021, 52.1% had, or were intending to have their child vaccinated; 30.1% reported they might vaccine their child; and 17.8% reported they would not vaccinate their child. Compared to vaccine-accepting parents, hesitant parents were more likely to be younger, less educated, poorer, to not know somebody who was sick from COVID-19, to believe the COVID-19 vaccines were unsafe, and to hold negative beliefs about scientists and healthcare professionals. Vaccine-resistant parents were more likely to be younger, living alone, to distrust scientists, and to believe the COVID-19 vaccines were unsafe. Public health messaging should target younger, lower income parents with clear information about the safety of COVID-19 vaccines for children.

RESUMO

Xenotransplantation using porcine donors is rapidly approaching clinical applicability as an alternative therapy for treatment of many end-stage diseases including type 1 diabetes. Porcine neonatal islet cell clusters (NICC) have normalised blood sugar levels for relatively short periods in the preclinical diabetic rhesus model but have met with limited success in the stringent baboon model. Here we report that NICC from genetically modified (GM) pigs deleted for αGal and expressing the human complement regulators CD55 and CD59 can cure diabetes long-term in immunosuppressed baboons, with maximum graft survival exceeding 22 months. Five diabetic baboons were transplanted intraportally with 9,673 - 56,913 islet equivalents (IEQ) per kg recipient weight. Immunosuppression consisted of T cell depletion with an anti-CD2 mAb, tacrolimus for the first 4 months, and maintenance with belatacept and anti-CD154; no anti-inflammatory treatment or cytomegalovirus (CMV) prophylaxis/treatment was given. This protocol was well tolerated, with all recipients maintaining or gaining weight. Recipients became insulin-independent at a mean of 87 ± 43 days post-transplant and remained insulin-independent for 397 ± 174 days. Maximum graft survival was 675 days. Liver biopsies showed functional islets staining for all islet endocrine components, with no evidence of the inflammatory blood-mediated inflammatory reaction (IBMIR) and minimal leukocytic infiltration. The costimulation blockade-based immunosuppressive protocol prevented an anti-pig antibody response in all recipients. In conclusion, we demonstrate that genetic modification of the donor pig enables attenuation of early islet xenograft injury, and in conjunction with judicious immunosuppression provides excellent long-term function and graft survival in the diabetic baboon model.
