RESUMO

OBJECTIVES: Dermal regeneration templates (DRTs) are frequently used to treat scalp defects. The aim was to compare the time course of healing for DRTs in scalp defects with and without preoperative radiation. METHODS: The authors conducted a retrospective cohort study of DRT-based scalp reconstruction at 2 academic medical centers between 2013 and 2022. Information was collected on demographic variables, comorbidities, medication use, history of radiation, and DRT outcomes. The primary outcome was DRT loss, defined as exposed calvarium or DRT detachment based on postoperative follow-up documentation. Kaplan-Meier survival analysis and multivariable Cox proportional-hazard regressions were used to compare DRT loss in irradiated and nonirradiated defects. Multivariable logistic regressions were used to compare 30-day postoperative complications (infection, hematoma, or seroma) in irradiated and nonirradiated defects. RESULTS: In total, 158 cases were included. Twenty-eight (18%) patients had a preoperative history of radiation to the scalp. The mean follow-up time after DRT placement was 2.6 months (SD: 4.5 mo). The estimated probability of DRT survival at 2 months was 91% (95% CI: 83%-100%) in nonirradiated patients and 65% (95% CI: 48%-88%) in irradiated patients. In the 55 patients with a bony wound base, preoperative head radiation was associated with a higher likelihood of DRT loss (hazard ratio: 11). Half the irradiated defects experienced uncomplicated total wound closure using Integra Wound Matrix Dressing with or without second-stage reconstruction. CONCLUSIONS: Dermal regeneration template can offer durable coverage in nonirradiated scalp defects. Although DRT loss is more likely in irradiated scalp defects, successful DRT-based reconstruction is possible in select cases.

RESUMO

OBJECTIVE: To identify the most important health-related quality of life (HRQOL) domains and patient-reported outcomes after upper extremity transplantation (UET) in individuals with upper extremity amputation. DESIGN: Verbatim audio-recordings of individual interviews and focus groups were analyzed using qualitative, grounded theory-based methods to identify important domains of HRQOL and provide guidance for outcomes measurement after UET. SETTING: Individual interviews were conducted by phone. Focus groups were conducted at 5 upper extremity vascularized composite allotransplantation (VCA) centers in the US and at an international conference of VCA experts. PARTICIPANTS: Individual phone interviews were conducted with 5 individuals with lived experience of UET. Thirteen focus groups were conducted with a total of 59 clinical professionals involved in UET. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Not applicable. RESULTS: Twenty-eight key HRQOL domains were identified, including physical functioning and medical complications, positive and negative emotional functioning, and social participation, relations, and independence. We identified key constructs for use in evaluation of the potentially substantial physical, medical, social, and emotional effects of UET. CONCLUSIONS: This study provides an overview of the most important issues affecting HRQOL after UET, including several topics that are unique to individuals with UET. This information will be used to establish systematic, comprehensive, and longitudinal measurement of post-UET HRQOL outcomes.

RESUMO

ABSTRACT: COVID-19 has led to marked increases in healthcare worker distress. Studies of these phenomena are often limited to a particular element of distress or a specific subset of healthcare workers. We administered the Moral Injury Symptom Scale for Healthcare Professionals, Copenhagen Burnout Inventory, Patient Health Questionnaire-9, and Generalized Anxiety Disorder-7 via online survey to 17,000 employees of a large academic medical center between December 2021 and February 2022. A total of 1945 participants completed the survey. Across all roles, the prevalence of moral injury, burnout, depression, and anxiety were 40.9%, 35.3%-60.6%, 25.4%, and 24.8%, respectively. Furthermore, 8.1% had been bothered by thoughts that they would be better off dead or of hurting themselves for "several days" or more frequently. Healthcare workers across all roles and practice settings are experiencing unsustainable levels of distress, with 1 in 12 regularly experiencing thoughts of self-harm.

RESUMO

INTRODUCTION: Limitations in insurance coverage may cause patients to turn to crowdfunding to raise money for gender-affirming procedures. In this study, we analyze the impact of Medicaid insurance coverage on gender-affirming mastectomy campaigns posted on GoFundMe.com. METHODS: Between March 1 and 12, 2021, we accessed GoFundMe.com to analyze available campaigns requesting monetary contributions for gender-affirming mastectomy. Campaigns were identified using the search term "top surgery" followed by the state's name. Duplicate campaigns, campaigns whose primary goal was not gender-affirming mastectomy, and ongoing campaigns were excluded. Campaigns were then categorized according to their state's coverage of gender-affirming surgery: explicit exclusion (EE), explicit inclusion (EI), or no explicit statement of gender-affirming care. We collected data on the number of donors and shares, the fundraising goal, and the total amount raised for each campaign. Common themes within campaign narratives were identified and assessed by each reviewer. Finally, we collected data on the photographs posted by campaign creators. RESULTS: Our search yielded 790 campaigns, with an overall mean of 58 ± 99 donors and 212 ± 288 shares. The mean fundraising goal and amount raised among all campaigns were $6811 ± $5027 and $2579 ± $3072, respectively. Fundraising goals were most likely to be met in an EI state than an EE state (26.3% vs 8.1%; P < 0.001). The mean amount sought was highest in EE states and lowest in EI states, whereas the mean amount raised was lowest in EE states and highest in EI states. Of the campaigns, 97.1% mentioned personal or situational characteristics in the narrative section; 16.2% of all campaigns expressed negative feelings about posting on GoFundMe.com to raise money for their surgeries. CONCLUSION: Disparities in health care coverage of gender-affirming surgeries were seen between state categories, with a decreased need for crowdfunding in states explicitly including coverage of gender-affirming surgery. Many transgender patients used crowdfunding to pay for transition-related health care costs, relying on the kindness of strangers and their social network at the expense of their personal privacy. Expansion of legislative coverage of gender-affirming surgeries may alleviate some of this financial burden and reduce transgender patients' reliance on crowdfunding campaigns.

RESUMO

PURPOSE: We performed a qualitative study to understand the psychosocial factors associated with success in upper-extremity vascularized composite allotransplantation from the perspective of transplant providers. METHODS: We recruited 13 providers actively involved in upper-extremity vascularized composite allotransplantation. Participants included physicians, nurses, social workers, occupational therapists, and research administrators. We conducted semistructured face-to-face focus group interviews using a guide that explored providers' perceptions of qualities contributing to transplant outcome. Topics included social support networks and their influence on recovery, barriers to treatment compliance and successful posttransplant rehabilitation, and the process of setting patients' expectations. We performed a thematic analysis that produced a list of themes, subthemes, and proposed hypotheses explaining how the themes related to the study's guiding questions. RESULTS: The analysis identified numerous factors that contribute to transplant success: (1) recipients' prior experiences modify their ability to cope and adapt after transplantation, (2) behaviors and characteristics such as positivity influence candidacy and may be predictive of successful outcomes, and (3) social support is essential for improved function and compliance. The provider care team cited difficulty in predicting recipient compliance and in setting realistic expectations. CONCLUSIONS: Motivated recipients with developed coping and resiliency, a positive attitude, and stable, physically-able caregivers are perceived by providers to have greater success after transplantation. CLINICAL RELEVANCE: Findings from this work may help providers determine optimal candidates for upper-extremity vascularized composite allotransplantation.

RESUMO

BACKGROUND: Recent progress in biomechatronics and vascularized composite allotransplantation have occurred in the absence of congruent advancements in the surgical approaches generally utilized for limb amputation. Consideration of these advances, as well as of both novel and time-honored reconstructive surgical techniques, argues for a fundamental reframing of the way in which amputation procedures should be performed. METHODS: We review sentinel developments in external prosthetic limb technology and limb transplantation, in addition to standard and emerging reconstructive surgical techniques relevant to limb modification, and then propose a new paradigm for limb amputation. RESULTS: An approach to limb amputation based on the availability of native tissues is proposed, with the intent of maximizing limb function, limiting neuropathic pain, restoring limb perception/proprioception and mitigating limb atrophy. CONCLUSIONS: We propose a reinvention of the manner in which limb amputations are performed, framed in the context of time-tested reconstructive techniques, as well as novel, state-of-the-art surgical procedures. Implementation of the proposed techniques in the acute setting has the potential to elevate advanced limb replacement strategies to a clinical solution that perhaps exceeds what is possible through traditional surgical approaches to limb salvage. We therefore argue that amputation, performed with the intent of optimizing the residuum for interaction with either a bionic or a transplanted limb, should be viewed not as a surgical failure, but as an alternative form of limb reconstruction.

RESUMO

PURPOSE: We performed a qualitative study to understand psychosocial factors associated with perceived success of upper-extremity vascularized composite allotransplantation (VCA). We interviewed transplant recipients and their primary caregivers. METHODS: We recruited 4 upper-extremity VCA recipients and primary caregivers for 3 of them. We conducted semistructured face-to-face interviews using a guide that explored participants' transplantation experiences. Topics included comparison of pretransplant and posttransplant expectations, reflections on factors contributing to the success of the transplant experience, and posttransplant rehabilitation and functioning. We performed a thematic analysis that produced a list of themes, subthemes, and proposed hypotheses explaining how the themes related to the study's guiding questions. RESULTS: Participants described several factors as contributing to the success of the transplant experience, including developing realistic expectations about posttransplant function and lifelong immunosuppression, support from one's community and particularly the primary caregiver, and framing the experience in a positive light. Social, aesthetic, and other values unique to the hands, as opposed to prosthetics, motivated recipients to undergo VCA despite its inherent risk and uncertainties. CONCLUSIONS: Despite inherent challenges, undergoing VCA was viewed as worthwhile to regain benefits unique to hands. Participants met the challenges of the transplant process through setting realistic expectations, strong social support, and a positive perspective. CLINICAL RELEVANCE: Findings from this work may help clinicians and prospective patients to prepare for and set appropriate expectations of VCA.

RESUMO

In the past 20 years, reconstructive transplantation (RT) has emerged as a viable reconstructive option for carefully selected patients. More than 100 upper extremity and 40 face transplants have been performed worldwide to date. Concomitantly, the portfolio of reconstructive transplantation has been extended by additional procedures such as lower extremities, abdominal wall, neck, uterus, genitourinary, and pediatric transplants. In the present review article, we aim to summarize the current state of knowledge about this exciting field.

RESUMO

PURPOSE: To date, there have been over 100 upper extremity transplantations (UET) performed worldwide. However, little data are available regarding institutional screening practices or description of the population of patients that seek transplantation as a treatment modality for their upper extremity disabilities. We performed a review of our institutional experience in an attempt to better understand our referral patterns and identify factors that may be associated with successful screening. METHODS: Contact demographic data, injury characteristics, and mode of referral were retrospectively reviewed from 2010 through 2015. Differences in demographic data, injury-related characteristics, and clinical trial outcomes were assessed with the Chi-square test or Fisher exact test. RESULTS: There were a total of 89 UET contacts. The average age was 35.2 years, with most contacts being white (n = 24). The majority were male (n = 66; 75.0%) and the most common indication for referral was trauma (n = 43; 55.8%). Of the 89 contacts, 20 (22.5%) were physician referrals and 69 (77.5%) were self-referrals. Physician referrals led to the most screened and accepted contacts, whereas self-referrals more often led to immediate exclusion. CONCLUSIONS: This study gives an overview of the demographic composition of our UET contacts, with a specific emphasis on mode of referral. We have identified that physician referrals have led to more screened and accepted patients versus self-referred individuals. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic, Level IV.

RESUMO

BACKGROUND: Although rodent models have been used extensively for surgical research, their use is limited in microsurgical tissue transfer due to their small size and the small size of their vessels and nerves. Also, fundamental anatomic differences may make rodent surgical models hard to extrapolate to humans. METHODS: In this report, the authors present a rabbit model for studying free tissue transfer and nerve regeneration using the innervated free gracilis muscle flap. In providing this report, the authors are hopeful that this model could become a standard investigative method for future investigators to employ in other translational endeavors. RESULTS: The authors have completed 12 innervated gracilis muscle transfers with 2 surgical site infections requiring antibiotic treatment and postoperative wound care. There were no complications related to flap-viability in the study over an average follow-up of 9 months. The return of muscle function with nerve coaptation is seen initially around 12 weeks and complete return of function occurs by 20 weeks. CONCLUSIONS: Rabbits are comparatively small, easily available, easy to handle, and cost-effective experimental models. Use of the innervated gracilis muscle free flap in rabbits can provide an excellent and economic model for free tissue transfer and reinnervation studies.

RESUMO

BACKGROUND: "Medical tourism" has gained popularity over the past few decades. This is particularly common with patients seeking elective cosmetic surgery in the developing world. However, the risk of severe and unusual infectious complications appears to be higher than for patients undergoing similar procedures in the United States. OBJECTIVES: The authors describe their experience with atypical mycobacterial infections in cosmetic surgical patients returning to the United States postoperatively. METHODS: A review of patient medical records presenting with infectious complications after cosmetic surgery between January 2010 and July 2015 was performed. Patients presenting with mycobacterial infections following cosmetic surgery were reviewed in detail. An extensive literature review was performed for rapid-growing mycobacteria (RGM) related to cosmetic procedures. RESULTS: Between January 2010 and July 2015, three patients presented to our institution with culture-proven Mycobacterium abscessus at the sites of recent cosmetic surgery. All had surgery performed in the developing world. The mean age of these patients was 36 years (range, 29-44 years). There was a delay of up to 16 weeks between the initial presentation and correct diagnosis. All patients were treated with surgical drainage and combination antibiotics with complete resolution. CONCLUSIONS: We present series of patients with mycobacterial infections after cosmetic surgery in the developing world. This may be related to the endemic nature of these bacteria and/or inadequate sterilization or sterile technique. Due to low domestic incidence of these infections, diagnosis may be difficult and/or delayed. Consulting physicians should have a low threshold to consider atypical etiologies in such scenarios. LEVEL OF EVIDENCE: 5 Therapeutic.

RESUMO

Metastatic tumors are the most common cranial neoplasms in adults. Skull metastases from rare primary tumors, such as cholangiocarcinoma or pancreatic neuroendocrine tumor, are extremely uncommon and rarely reported. Given the scarcity and variation of these rare skull metastases, treatments and outcomes of such patients are of interest to treating surgeons. The authors describe the treatment algorithm, course, and outcomes of 2 patients with rare gastrointestinal skull metastases. The first patient had intrahepatic cholangiocarcinoma metastatic to the skull, while the second patient developed a solitary skull metastasis secondary to a pancreatic neuroendocrine tumor. As part of this report, the authors include a literature review of rare skull metastases as well as the treatment of these 2 patients. Both the patients ultimately underwent successful resection of the tumor for relief of their clinical symptoms. Wide resections in both patients necessitated reconstruction using a free latissimus dorsi muscle flap in both the patients. Preoperative embolization of the hypervascular cholangiocarcinoma skull metastasis was performed prior to resection in the first patient. To date, there have been only 4 such reports of skull metastases from intrahepatic cholangiocarcinoma and limited reported cases of isolated skull metastases from a pancreatic neuroendocrine tumor.In patients with large or numerous skull metastasis from rare primary tumors, surgical resection should be considered for symptomatic improvement. In cases of hypervascular lesions, preoperative embolization can be considered to decrease the intraoperative bleeding. Free tissue transfers using myocutaneous flaps such as latissimus dorsi help in obliterating dead space, and creating a healthy soft tissue envelope to withstand postoperative radiation treatment. In addition, a chimeric flap can be designed to include additional muscle or soft tissue to obliterate and exclude the sinus cavities.

RESUMO

Vascularized composite allotransplantation (VCA) of the upper extremity is an established restorative procedure for selected patients with acquired upper limb loss. The majority of upper limb VCAs performed worldwide have been for victims of various forms of trauma. However, in the developed world, amputation following severe sepsis seems to be an increasingly common indication for referral to hand transplant programs. Unlike trauma patients with isolated limb injuries, patients with amputations as a complication of sepsis have survived through a state of global tissue hypoperfusion and multisystem organ failure with severe, enduring effects on the entire body's physiology. This article reviews the unique considerations for VCA candidacy in postsepsis patients with upper limb amputation. These insights may also be relevant to postsepsis patients undergoing other forms of transplantation or to VCA patients requiring additional future solid organ transplants.

RESUMO

BACKGROUND: High-risk patients undergoing abdominoperineal resection and pelvic exenteration may benefit from immediate flap reconstruction. However, there is currently no consensus on the ideal flap choice or patient for whom this is necessary. This study aimed to evaluate the long-term outcomes of using pedicled gracilis flaps for pelvic reconstruction and to analyze predictors of postoperative complications. METHODS: This was a retrospective review of a single reconstructive surgeon's cases between January 2012 and June 2021 identifying patients who underwent perineal reconstruction secondary to oncologic resection. Preoperative and outcome variables were collected and analyzed to determine the risk of developing minor and major wound complications. RESULTS: A total of 101 patients were included in the study with most patients (n = 88) undergoing unilateral gracilis flap reconstruction after oncologic resection. The mean follow-up period was 75 months. Of 101 patients, 8 (7.9%) developed early major complications, and an additional 13 (12.9%) developed late major complications. Minor complications developed in 33 patients (32.7%) with most cases being minor wound breakdown requiring local wound care. Most patients (n = 92, 91.1%) did not develop donor site complications. Anal cancer was significantly associated with early major complications, whereas younger age and elevated body mass index were significant predictors of developing minor wound complications. CONCLUSIONS: This study builds on our previous work that demonstrated the long-term success rate of gracilis flap reconstruction after large pelvic oncologic resections. A few patients developed donor site complications, and perineal complications were usually easily managed with local wound care, thus making the gracilis flap an attractive alternative to abdominal-based flaps.

RESUMO

Transcriptional profiling demonstrated markedly reduced type I IFN gene expression in untreated mycosis fungoides (MF) skin lesions compared with that in healthy skin. Type I IFN expression in MF correlated with antigen-presenting cell-associated IRF5 before psoralen plus UVA therapy and epithelial ULBP2 after therapy, suggesting an enhancement of epithelial type I IFN. Immunostains confirmed reduced baseline type I IFN production in MF and increased levels after psoralen plus UVA treatment in responding patients. Effective tumor clearance was associated with increased type I IFN expression, enhanced recruitment of CD8+ T cells into skin lesions, and expression of genes associated with antigen-specific T-cell activation. IFNk, a keratinocyte-derived inducer of type I IFNs, was increased by psoralen plus UVA therapy and expression correlated with upregulation of other type I IFNs. In vitro, deletion of keratinocyte IFNk decreased baseline and UVA-induced expression of type I IFN and IFN response genes. In summary, we find a baseline deficit in type I IFN production in MF that is restored by psoralen plus UVA therapy and correlates with enhanced antitumor responses. This may explain why MF generally develops in sun-protected skin and suggests that drugs that increase epithelial type I IFNs, including topical MEK and EGFR inhibitors, may be effective therapies for MF.

RESUMO

BACKGROUND: Candidate selection for upper extremity transplantation remains an inherently subjective process. This work evaluated the effect that psychosocial factors have on outcomes, both to standardize evaluation of potential candidates and in optimizing these factors prior to transplantation. Our goal was to measure and quantify the risk that various psychosocial factors have on transplant outcomes. METHODS: Given that we do not have sufficient post-transplant patients to examine specific factors, we chose to have experts in the field evaluate hypothetical patients based on their experience. We used a Generalized Estimating Equation to estimate and compare surgical candidacy scores using patient scenario vignettes based on the presence or absence of permutations of the following: (1) depression; (2) participation in occupational therapy (OT); (3) expectation of post-transplant function; (4) punctuality; and (5) family support were given to experts in the field. RESULTS: This work suggests there is a decrease in predicted success with increasing numbers of negative factors with participation in OT and realistic expectations of outcomes being most important. An increase in the summarizing risk score from 0 to 1.7 was associated with a decrease in the outcome surgical candidacy score from 8.6 to 5.3, meaning candidates with 2 risk factors would often observe a large drop in surgical candidacy score. CONCLUSIONS: Focusing on optimizing psychosocial variables in transplant candidates may help improve hand transplant success.

RESUMO

To explore the mental health impacts of the COVID-19 pandemic on healthcare workers in Massachusetts and identify potential strategies to maintain the healthcare workforce we conducted a sequential exploratory mixed methods study. Fifty-two individuals completed interviews from April 22nd - September 7th, 2021; 209 individuals completed an online survey from February 17th - March 23rd, 2022. Interviews and surveys asked about the mental health impacts of working in healthcare during the COVID-19 pandemic, burnout, longevity in the workplace, and strategies for reducing attrition. Interview and survey participants were predominantly White (56%; 73%, respectively), female (79%; 81%) and worked as physicians (37%; 34%). Interviewees indicated high stress and anxiety levels due to frequent exposure to patient deaths from COVID-19. Among survey respondents, 55% reported worse mental health than before the pandemic, 29% reported a new/worsening mental health condition for themselves or their family, 59% reported feeling burned out at least weekly, and 37% intended to leave healthcare in less than 5 years. To decrease attrition, respondents suggested higher salaries (91%), flexible schedules (90%), and increased support to care for patients (89%). Healthcare workers' experiences with death, feeling unvalued, and overworked resulted in unprecedented rates of burnout and intention to leave healthcare.

RESUMO

Muenke syndrome caused by the FGFR3 Pro250Arg mutation is associated with craniosynostosis, hearing loss, and various bony anomalies. Although this mutation is involved in bone growth and development, bony tumors are rare in this condition. We describe a patient with a molecular diagnosis of Muenke syndrome who also presented with multiple osteochondromas of the upper and lower extremities. This association has only been described once before in a patient with an isolated osteochondroma of the proximal tibia. Altered expression of FGFR3, an important mediator of chondrocyte proliferation and differentiation during in the growth plates of long bones, may help to explain the development of osteochondromatous lesions in this patient.
