RESUMO

Head and neck cancer (HNC) patients benefit from craniofacial reconstruction, but no clear guidance exists for rehabilitation timing. This meta-analysis aims to clarify the impact of oncologic treatment order on implant survival. An algorithm to guide placement sequence is also proposed in this paper. PubMed, Embase, and Web of Science were searched for studies on HNC patients with ablative and fibula-free flap (FFF) reconstruction surgeries and radiotherapy (RTX). Primary outcomes included treatment sequence, implant survival rates, and RTX dose. Of 661 studies, 20 studies (617 implants, 199 patients) were included. Pooled survival rates for implants receiving >60 Gy RTX were significantly lower than implants receiving < 60 Gy (82.8% versus 90.1%, P=0.035). Placement >1 year after RTX completion improved implant survival rates (96.8% versus 82.5%, P=0.001). Implants receiving pre-placement RTX had increased survival with RTX postablation versus before (91.2% versus 74.8%, P<0.001). One hundred seventy-seven implants were placed only in FFF with higher survival than implants placed in FFF or native bone (90.4% versus 83.5%, P=0.035). Radiotherapy is detrimental to implant survival rates when administered too soon, in high doses, and before tumor resection. A novel evidence-based clinical decision-making algorithm was presented for utilization when determining the optimal treatment order for HNC patients. The overall survival of dental prostheses is acceptable, reaffirming their role as a key component in rehabilitating HNC patients. Considerations must be made regarding RTX dosage, timing, and implant location to optimize survival rates and patient outcomes for improved functionality, aesthetics, and comfort.

RESUMO

BACKGROUND: Osteocutaneous fibula free flaps (FFFs) are a fundamental component of reconstructive surgery in the head and neck region, particularly after traumatic injuries or oncologic resections. Despite their utility, FFFs are associated with various postoperative complications, such as infection, flap failure, and donor site morbidity, impacting up to 54% of cases. This study aimed to investigate the influence of socioeconomic variables, with a particular focus on median household income (MHI), on the incidence of postoperative complications in FFF reconstruction for head and neck cancer. METHODS: A retrospective analysis of 80 patients who underwent FFF reconstruction for head and neck cancer at a single center from 2016 to 2022 was conducted. Demographic and patient characteristics, including race, MHI, insurance type, history of radiation therapy, and TNM (tumor, node, metastasis) cancer stage, were evaluated. Logistic regression, controlling for comorbidities, was used to assess the impact of MHI on 30-, 90-, and 180-day postoperative complications. RESULTS: The patient population was predominantly male (n = 51, 63.8%) and White (n = 63, 78.8%), with the majority falling within the $55,000 to $100,000 range of MHI (n = 51, 63.8%). Nearly half of the patients had received neoadjuvant radiation treatment (n = 39, 48.75%), and 36.25% (n = 29) presented with osteoradionecrosis. Logistic regression analysis revealed that the $55,000-$100,000 MHI group had significantly lower odds of developing complications in the 0- to 30-day postoperative period when compared with those in the <$55,000 group (odds ratio [OR], 0.440; 95% confidence interval [CI], 0.205-0.943; P = 0.035). This trend persisted in the 31- to 90-day period (OR, 0.136; 95% CI, 0.050-0.368; P < 0.001) and was also observed in the likelihood of flap takeback. In addition, the $100,000-$150,000 group had significantly lower odds of developing complications in the 31- to 90-day period (OR, 0.182; 95% CI, 0.035-0.940; P = 0.042). No significant difference was found in the >$150,000 group. CONCLUSIONS: Median household income is a significant determinant and potentially a more influential factor than neoadjuvant radiation in predicting postoperative complications after FFF reconstruction. Disparities in postoperative outcomes based on income highlight the need for substantial health care policy shifts and the development of targeted support strategies for patients with lower MHI.

RESUMO

BACKGROUND: Tissue expansion has been widely used to reconstruct soft tissue defects following burn injuries in pediatric patients, allowing for satisfactory cosmetic and functional outcomes. Factors impacting the success of tissue expander (TE)-based reconstruction in these patients are poorly understood. Herein, we aim to determine the risk factors for postoperative complications following TE-based reconstruction in pediatric burn patients. METHODS: A retrospective review of pediatric patients who underwent TE placement for burn reconstruction from 2006 to 2019 was performed. Primary outcomes were major complications (TE explantation, extrusion, replacement, flap necrosis, unplanned reoperation, readmission) and wound complications (surgical site infection and wound dehiscence). Descriptive statistics were calculated. The association between primary outcomes, patient demographics, burn characteristics, and TE characteristics was assessed using the chi-squared, Fisher's exact, and Mann-Whitney U tests. RESULTS: Of 28 patients included in the study, the median [interquartile range (IQR)] age was 6.5 (3.3-11.8) years, with a follow-up of 12 (7-32) months. The majority were males [n = 20 (71%)], Black patients [n = 11 (39%)], and experienced burns due to flames [n = 78 (29%)]. Eleven (39%) patients experienced major complications, most commonly TE premature explantation [n = 6 (21%)]. Patients who experienced major complications, compared to those who did not, had a significantly greater median (IQR) % total body surface area (TBSA) [38 (27-52), 10 (5-19), P = 0.002] and number of TEs inserted [2 (2-3), 1 (1-2), P = 0.01]. Ten (36%) patients experienced wound complications, most commonly surgical site infection following TE placement [n = 6 (21%)]. Patients who experienced wound complications, compared to those who did not, had a significantly greater median (IQR) %TBSA [35 (18-45), 19 (13-24), P = 0.02]. CONCLUSION: Pediatric burn injuries involving greater than 30% TBSA and necessitating an increasing number of TEs were associated with worse postoperative complications following TE-based reconstruction.

RESUMO

BACKGROUND: Tissue expansion is a powerful tool for reconstruction of pediatric soft-tissue pathologies, but complication rates for children have been reported as high as 40%. Infection and implant extrusion lead to premature removal and delays in reconstruction. Expanding the head and neck is uniquely challenging because the confluence of facial aesthetic units must be respected. These challenges have prompted the senior author's creation of an aesthetic-unit based algorithm. METHODS: A retrospective study of pediatric patients who underwent cervicofacial tissue expander placement by the senior author (R.J.R) was performed over a 17-year period. Predictor variables included age, sex, race, indication, number of expanders placed at each operation, serial expansion, expander type, expander size, home versus clinic inflation, and prophylactic antibiotics. Univariate and multivariate analyses were performed to identify risk factors for complications. RESULTS: An aesthetic-unit based reconstructive algorithm is proposed. Forty-eight pediatric patients had 111 cervicofacial tissue expanders placed. Twenty expanders were associated with complications (18%) for surgical site-infection (12.6%), extrusion (4.5%), and expander deflation (6.3%). Expanders placed for congenital nevi (p=0.042) and use of textured expander (p=0.027) were significantly associated with decreased complications. When controlling for covariates, serial expansion of the same site was associated with increased rates of readmission (p=0.027) after having just one prior expander. Iatrogenic ectropion occurred in 13.5% of the study population; expanders with at least one complication during tissue expansion were significantly associated with incidence of iatrogenic ectropion (p=0.026). CONCLUSION: By using an aesthetic-unit based algorithm, reconstructive outcomes can be optimized for pediatric cervicofacial tissue expansion.

RESUMO

BACKGROUND: It can be argued that individuals in the transgender and gender nonbinary (TGNB) community suffer from a similar impact on quality of life in the face of gender dysphoria, with psychosocial and physical consequences. Indications for penile allotransplantation for patients wishing to undergo gender affirmation surgery have yet to be elucidated, but technical lessons for feasibility can be gleaned from penis transplants that have already been performed on cisgender males to date. METHODS: This study investigates the theoretical feasibility for penile-to-clitoral transplantation, prior penile transplants, and current multidisciplinary gender affirmation health care modalities. RESULTS: Penile allotransplantation offers a potential solution for individuals in the TGNB community for a more aesthetic penis, improved erectile function without the need of a prosthesis, optimal somatic sensation, and improved urethral outcomes. CONCLUSION: Questions remain about ethics, patient eligibility, and immunosuppressive sequelae. Before these issues are addressed, feasibility of this procedure must be established.

RESUMO

BACKGROUND: Calvarial defects are severe injuries that can result from a wide array of etiologies. Reconstructive modalities for these clinical challenges include autologous bone grafting or cranioplasty with biocompatible alloplastic materials. Unfortunately, both approaches are limited by factors such as donor site morbidly, tissue availability, and infection. Calvarial transplantation offers the potential opportunity to address skull defect form and functional needs by replacing "like-with-like" tissue but remains poorly investigated. METHODS: Three adult human cadavers underwent circumferential dissection and osteotomy to raise the entire scalp and skull en-bloc. The vascular pedicles of the scalp were assessed for patency and perfused with color dye, iohexol contrast agent for computed tomography (CT) angiography, and indocyanine green for SPY-Portable Handheld Imager assessment of perfusion to the skull. RESULTS: Gross changes were appreciated to the scalp with color dye, but not to bone. CT angiography and SPY-Portable Handheld Imager assessment confirmed perfusion from the vessels of the scalp to the skull beyond midline. CONCLUSION: Calvarial transplantation may be a technically viable option for skull defect reconstruction that requires vascularized composite tissues (bone and soft tissue) for optimal outcomes.

RESUMO

BACKGROUND: Tissue expansion is a well-established approach to soft tissue reconstruction in the pediatric population for lower extremity pathologies. Unfortunately, complication rates range from 19% to 40% in literature, including infection and implant extrusion, leading to delays in reconstruction. These challenges have prompted investigation toward categorizing risk factors for lower extremity tissue expander placement. METHODS: A retrospective study of pediatric patients who underwent lower extremity tissue expander placement by the senior author (R.J.R.) was performed over a 16-year period. Patient charts were reviewed to categorize baseline and operative characteristics. Primary outcome variables were surgical-site infection, expander extrusion, and expander deflation. Univariate and multivariate logistic regressions were performed ( α < 0.05). RESULTS: There were 59 tissue expanders in our cohort. The overall complication rate was 27.1% with a 77.2% successful reconstruction rate. Greater number of expanders placed during 1 operation is associated with 2.5 increased odds of having any complication and is associated with 0.4 decreased odds of having a successful reconstruction. Incisions made in scar tissue for expander placement appear to be associated with a greater than 7 times increased odds of readmission. CONCLUSIONS: Reconstruction of soft tissue pathologies using lower extremity tissue expanders in the pediatric population is an effective yet challenging technique. This study identified that the number of expanders inserted during 1 operation, incisions made over scar tissue, and expanders placed in the anterior thigh were correlated with having a negative impact on reconstructive outcomes. Extra care should be taken with patients who require multiple expanders during 1 operation and with choosing the location and incision of expander placement.

RESUMO

PURPOSE OF REVIEW: Penile transplantation has become an emerging option for patients with severe genital defects. Only transplantation restores anatomy, sexual, and reproductive function of the penis. However, penile transplantation comes with important technical, psychosocial, ethical, and surgical challenges that must be considered for successful implementation. Indications for penile transplantation have yet to be clearly elucidated. RECENT FINDINGS: Since 2006, only five penile transplants have been performed globally. Four of the five transplants have been performed following traumatic defects, and one was performed following a total penectomy from squamous cell carcinoma. Only two of the five penile transplants remain intact. However, long-term outcomes are encouraging with optimal surgical planning, patient selection, and immunologic compliance. Clinical implications and ethical considerations are discussed. SUMMARY: Penile transplantation is a novel solution for penile defects not amenable to traditional reconstructive approaches. With an evidence-based surgical technique, potential advantages include improved urinary function, sensation, and cosmesis. While patient selection is challenging, there is an ongoing effort to identify potential candidates. Indications are discussed in this article.

RESUMO

BACKGROUND: The COVID-19 pandemic significantly impacted hospital resources and patient care, although its effect on free tissue transfer procedures is poorly understood. We conducted the current study to investigate the potential impact of COVID-19 and its accompanying system shut-downs on the surgical outcomes of patients undergoing free flap procedures. METHODS: Patients undergoing free tissue transfer procedures were identified from the National Surgical Quality Improvement Program (NSQIP) database from 2016 to 2020. We used 2016-2019 as baseline (pre-pandemic) data to compare with 2020 (peri-pandemic). We divided the patients into the following 3 groups: all patients undergoing free tissue transfer, breast reconstruction free tissue transfer, and non-breast free tissue transfer cases. Outcomes of interest included patient morbidity/mortality, time to surgery, time to takeback, and length of hospital stay. We used Pearson's chi-square and Fisher's exact tests to assess categorical variables. Wilcoxon's ranked sign tests and ANOVA tests were used for non-parametric and parametric continuous variables, respectively. Significance was set at alpha < 0.05. RESULTS: When comparing peri-pandemic to pre-pandemic rates, patient morbidity and mortality and unplanned primary or secondary takeback operations were both significantly higher in all 3 groups peri-pandemic. Median time to primary or secondary takeback operation was also significantly greater peri-pandemic. CONCLUSION: Patients undergoing flap procedures peri-pandemic had an overall increase in median morbidity and mortality, unplanned primary or secondary takebacks, and median number of days to takebacks compared to the pre-pandemic period. This is concerning given that any future protocols instituted can have detrimental effects on patients who receive a free tissue transfer procedure.

RESUMO

INTRODUCTION: The socioeconomic diversity of residents, fellows, and faculty members in any medical or surgical specialty is currently unknown making it difficult to understand socioeconomic status (SES) disparities and create programs to improve diversity. Additionally, the career trajectories of residents and faculty members who come from different SES backgrounds have not been explored. We have performed a survey-based research study to understand the SES composition and career trajectories of residents and faculty members within U.S. Plastic and Reconstructive Surgery (PRS) residency programs. METHODS: An anonymous online survey was administered to 754 recipients within plastic surgery residency programs in the United States. Self-reported SES information such as household income prior to age 18 and parental education level was collected. Data regarding career trajectories was obtained through questions about away rotations and research productivity. RESULTS: A total of 196 fellows, and faculty members participated in the study, with an estimated survey respondent rate of 25.9%. Only 9.9% (10 of 101) of residents and fellows reported a childhood (under age 18) family income less than $40,000. When analyzing parental education and occupation (EO-status), 42.6% (43 of 101) of residents and fellows had at least 1 parent in an executive, managerial, or professional position with a doctorate/professional degree. Low-income and low EO-status were associated with increased utilization of federal and state assistance programs (p = 0.0001) and approval for AAMC's Fee Assistance Program (FAP) (p = 0.0001). Residents and fellows who identified as White were not as likely to be from low EO-status households as those who identified as Asian (OR 0.3 and p = 0.015 vs. OR 2.9 and p = 0.038). Residents and fellows from low EO-status backgrounds were more likely to take a gap in education (87% vs. 65.4%, p = 0.047) compared to their high EO-status peers. Notably, more current residents and fellows performed away rotations and had first-author publications during or before medical school compared to full professors (p = 0.0001). CONCLUSION: Understanding the backgrounds and career trajectories of trainees and faculty in medicine is essential, yet it has not been performed at the resident or faculty level. This survey is the first to demonstrate the lack of socioeconomic diversity in a specialty (PRS) and identifies variation in career trajectories among those from different SES backgrounds. Large-scale research efforts are necessary to understand current SES diversity and barriers encountered by trainees and educators from low-SES backgrounds in all medical and surgical specialties.

RESUMO

BACKGROUND: Patients with nonsyndromic craniosynostosis (NSC) generally undergo corrective surgery before 1 year of age to the mitigate morbidities and risks of delayed repair. The cohort of patients who receive primary corrective surgery after 1 year and factors associated with their gaps to care is poorly characterized in literature. METHODS: A nested case-control study was conducted for NSC patients who underwent primary corrective surgery at our institution and affiliates between 1992 and 2022. Patients whose surgery occurred after 1 year of age were identified and matched 1:1 by surgical date to standard-care control subjects. Chart review was conducted to gather patient data regarding care timeline and sociodemographic characteristics. RESULTS: Odds of surgery after 1 year of age were increased in Black patients (odds ratio, 3.94; P < 0.001) and those insured by Medicaid (2.57, P = 0.018), with single caregivers (4.96, P = 0.002), and from lower-income areas (+1% per $1000 income decrease, P = 0.001). Delays associated with socioeconomic status primarily impacted timely access to a craniofacial provider, whereas caregiver status was associated with subspecialty level delays. These disparities were exacerbated in patients with sagittal and metopic synostosis, respectively. Patients with multisuture synostosis were susceptible to significant delays related to familial strain (foster status, insurer, and English proficiency). CONCLUSIONS: Patients from socioeconomically strained households face systemic barriers to accessing optimal NSC care; disparities may be exacerbated by the diagnostic/treatment complexities of specific types of craniosynostosis. Interventions at primary care and craniofacial specialist levels can decrease health care gaps and optimize outcomes for vulnerable patients.

RESUMO

BACKGROUND: Mandibular fractures are the most common of pediatric facial fractures. The effect of race on management/outcomes in these injuries has not been previously studied. Given the significant association between race and healthcare outcomes in many other pediatric conditions, an in-depth study of race as related to mandibular fractures in the pediatric patient population is warranted. METHODS: This was a 30-year retrospective, longitudinal study of pediatric patients who presented to a single institution with mandibular fractures. Patient data were compared between patients of different races and ethnicities. Demographic variables, injury characteristics, and treatment variables were analyzed to find predictors of surgical treatment and posttreatment complications. RESULTS: One hundred ninety-six patients met inclusion criteria, of whom 49.5% were White, 43.9% were Black, 0.0% were Asian, and 6.6% were classified as "other." Black and "other" patients were more likely than their White counterparts to be injured as pedestrians (P = 0.0005). Black patients were also more likely than White patients or "other" patients to be injured by assault than by sports-related injuries or animal-related accidents (P = 0.0004 and P = 0.0018, respectively). Race or ethnicity were not found to be a predictor of receiving surgical treatment (ORIF) or of posttreatment complications. The posttreatment rates for all the complications observed were comparable among all race and ethnic groups. Higher mandible injury severity score (odds ratio [OR], 1.25), condyle fracture (OR, 2.58), and symphysis fracture (OR, 3.20) were positively correlated with receiving ORIF as treatment. Mandible body fracture (OR, 0.36), parasymphyseal fracture (OR, 0.34), bilateral mandible fracture (OR, 0.48), and multiple mandibular fractures (OR, 0.34) were negatively correlated with receiving ORIF as treatment. Only high mandible injury severity score (OR, 1.10) was identified as an independent predictor of posttreatment complications. Lastly, Maryland's transition to an all-payer model in 2014 also had no impact on treatment modality; treatment of fractures among race and ethnicity were not significantly different pre- and post-2014. CONCLUSIONS: There is no difference in how patients are treated (surgically vs nonsurgically) and no difference in outcomes for patients based on race at our institution. This could be due to institutional ideology, services provided by a tertiary care center, or simply the more diverse patient population at baseline.

RESUMO

Central venous catheters (CVCs) are invaluable devices in large animal research as they facilitate a wide range of medical applications, including blood monitoring and reliable intravenous fluid and drug administration. Specifically, the tunneled multi-lumen Hickman catheter (HC) is commonly used in swine models due to its lower extrication and complication rates. Despite fewer complications relative to other CVCs, HC-related morbidity presents a significant challenge, as it can significantly delay or otherwise negatively impact ongoing studies. The proper insertion and maintenance of HCs is paramount in preventing these complications, but there is no consensus on best practices. The purpose of this protocol is to comprehensively describe an approach for the insertion and maintenance of a tunneled HC in swine that mitigates HC-related complications and morbidity. The use of these techniques in >100 swine has resulted in complication-free patent lines up to 8 months and no catheter-related mortality or infection of the ventral surgical site. This protocol offers a method to optimize the lifespan of the HC and guidance for approaching issues during use.

RESUMO

BACKGROUND: Prepectoral implant-based breast reconstruction is often supplemented by autologous fat grafting to optimize aesthetic outcomes. This usually entails several rounds of modest fat transfer to minimize risk of necrosis; however, the limits of fat grafting at expander exchange are not known. METHODS: A single-institution retrospective review from July 2016 to February 2022 was performed of all patients who underwent (1) mastectomy, (2) prepectoral tissue expander placement, (3) expander exchange for implant, and (4) at least one round of autologous fat transfer. Student t test and χ 2 test were used. RESULTS: A total of 82 breasts underwent a single round of fat grafting during implant placement (group 1); 75 breasts underwent fat grafting that occurred in multiple rounds and/or in delay to implant placement (group 2). Group 1 received more fat at the time of implant placement (100 mL; interquartile range, 55-140 mL; P < 0.001) and underwent fewer planned operative procedures compared with group 2 (1.0 vs 2.2, P < 0.001). Total fat volume in group 2 did not significantly exceed that of group 1 until after 3 rounds of fat transfer (128.5 mL; interquartile range, 90-130 mL; P < 0.01). There was no difference in the rate of fat necrosis between groups after the first round (15.9% vs 9.3%, P = 0.2) and final round (15.9% vs 12.0%, P = 0.5) of fat grafting. Complication rates were similar between groups (3.7% vs 8.0%, P = 0.2). CONCLUSIONS: A 2-stage approach of prepectoral tissue expander placement with single round of larger volume fat transfer at expander exchange reduces overall number of operative procedures without increased risks.

RESUMO

BACKGROUND: As the second cycle impacted by COVID-19, the 2022 Plastic and Reconstructive Surgery (PRS) Match maintained virtual interviews while offering a modest lift of subinternship restrictions. The residency application process continues to evolve, with changes such as pass/fail United States Medical Licensing Examination Step 1 reporting prompting programs to reconsider metrics of applicant success. It is critical to address the impact of board scores, mentorship, and resource availability on a diverse applicant population in the PRS Match. METHODS: A survey was electronically administered to students applying to a single institutional PRS residency program. The survey inquired about demographics, application statistics, mentorship experience, and match outcomes. Logistic regressions were modeled to assess for odds of matching into plastic surgery. RESULTS: In total, 151 responses were analyzed, a 49.7% response rate. Most participants were female (52.3%), White (68.9%), and not Hispanic/Latino (84.8%). The largest percentage of respondents had a faculty mentor only from their home institution (55.0%) and a resident mentor from only their home institution (32.3%). Participants with a faculty mentor from both a home and outside institution had 7.4 times the odds of matching into PRS ( P = 0.02) than students with no faculty mentorship. Students with dual-institution resident mentorship had 18.5 times higher the odds of matching compared with students with no resident mentorship ( P < 0.001). CONCLUSIONS: Subjective metrics, rather than objective scores, had the most influence on successfully matching into plastic surgery. As the PRS Match continues to become increasingly competitive, it behooves programs to provide equitable access to resources such as mentorship.

RESUMO

BACKGROUND: In 2022, the plastic and reconstructive surgery (PRS) match faced unprecedented system-wide transitions that have redefined conventional measures of applicant success. This challenges the equitable assessment of student competitiveness and diversity in the field. METHODS: A survey of demography, application content, and 2022 match outcomes was distributed to applicants to a single PRS residency program. Comparative statistics and regression models were performed to assess the predictive value of factors in match success and quality. RESULTS: A total of 151 respondents (response rate 49.7%) were analyzed. Although step 1 and step 2 CK scores were significantly higher among matched applicants, neither examination predicted match success. Most respondents (52.3%) were women, although gender was also not significantly associated with match success. Underrepresented in medicine applicants made up 19.2% of responses and 16.7% of matches, and the plurality of respondents (22.5%) were raised with a household income ≥$300,000. Both Black race and household income ≤$100,000 were associated with lower odds of scoring above a 240 on either step 1 or step 2 CK (Black: OR, 0.03 and 0.06; P < 0.05 and P < 0.001; income: OR, 0.07-0.47 and 0.1 to 0.8, among income subgroups), receiving interview offers (OR, -9.4; P < 0.05; OR, -11.0 to -5.4), and matching into PRS (OR, 0.2; P < 0.05; OR, 0.2 to 0.5), compared with White and high-income applicants, respectively. CONCLUSIONS: Systemic inequities in the match process disadvantage underrepresented in medicine candidates and those from lower household incomes. As the residency match continues to evolve, programs must understand and mitigate the impacts of bias in various application components.

RESUMO

INTRODUCTION: Children are uniquely vulnerable to injury because of near-complete dependence on caregivers. Unintentional injury is leading cause of death in children under the age of 14. Burns are one of the leading causes of accidental and preventable household injuries, with scald burns most common in younger children and flame burns in older ones. Education is a key tool to address burn prevention, but unfortunately these injuries persist. Critically, there is a paucity of literature investigating adult comprehension with respect to potential risks of household burns. To date, no study has been performed to assess management readiness for these types of injuries without seeking medical care. METHODS: Qualtrics™ surveys were distributed to laypersons via Amazon Mechanical Turk. Demographics were self-reported. The survey was divided into two parts, management knowledge, and risk identification. The management part involved a photograph of a first-degree pediatric burn injury and required identification of the degree of injury and three potential initial managements. The risk-identification section required correctly identifying the most common mechanisms of burn injury for different age groups followed by general identification of 20 household burn risks. Survey responses were analyzed using two-tailed Student's t-tests and chi-square analyses, univariate and multivariate analysis, and linear regression. RESULTS: Of the 467 respondents, the mean age was 36.57 years, and was 59.7% (279) male. Only 3.2% of respondents were able to correctly identify all 20 potential risks listed in our survey. Additionally, only 4.5% of respondents correctly identified all three appropriate initial management options (cool water, sterile gauze, and over-the-counter analgesics) without misidentifying incorrect options. However, 56.1% of respondents were able to select at least one correct management option. For image-based injury classification, the most common response was incorrectly second-degree with 216 responses (42.2%) and the second-most common response was correctly first-degree with 146 responses (31.3%). Most respondents claimed they would not seek medical attention for the injury presented in the photograph (77.7%). When comparing the responses of individuals with children to those without, there were no statistically significant differences in ability to assess household risks for pediatric burns. For the entire population of respondents, the mean score for correctly identifying risks was 38%. CONCLUSION: This study revealed a significant gap in public awareness of household risks for pediatric burns. Furthermore, while most individuals would not seek medical care for a first-degree pediatric burn injury, they were readily available to identify proper initial management methods. This gap in knowledge and understanding of household pediatric burn injuries should be addressed with increased burn injury prevention education initiatives and more parental counseling opportunities.

RESUMO

Since 2006, five penis transplants have been performed worldwide. Mixed outcomes have been reported, and two of the five penile transplants have required explantation. However, the long-term outcomes have been encouraging when compliance is implemented, whether standard induction and triple therapy maintenance, or single therapy maintenance. Follow-up monitoring of transplant recipients has enabled a synthesis of technical considerations for surgical success and has shown stable leukocyte counts and renal function after a donor bone-marrow-based immunomodulatory regimen followed by tacrolimus monotherapy as long as 3 years post-transplant, as well as continuous nerve regeneration of penile allografts 3 years post-transplant. Areas of uncertainty include the ethics of donor-recipient colour mismatch, surveillance for sexually transmitted infections and how to optimize patient compliance. Questions also remain with respect to the long-term immunological sequelae of penile tissue, functional outcomes, psychosocial implications and patient selection. Patient counselling should be modified to mention the possibility of long-term improvement in nerve regeneration and sufficient renal function with single-therapy maintenance, and to build a longitudinal dialogue and partnership between the patient and the multidisciplinary care team regarding the risks of sexually transmitted infection instead of surveillance.

RESUMO

Considerable controversy exists around the optimal age on which to operate for craniosynostosis. This study aims to use data from the American College of Surgeons National Surgical Quality Improvement Program-Pediatric to assess the impact of operative age on hospital stay and outcomes. After excluding patients who underwent endoscopic cranial vault remodeling, a total of 3292 patients met inclusion criteria in the National Surgical Quality Improvement Program-Pediatric between 2012 and 2019. Median age at surgery was 300 days (interquartile range: 204-494). Patients between 0 and 6 months underwent the highest proportion of complex cranial vault remodeling, Current Procedural Terminology 61,558 ( n =44, 7.7%) and Current Procedural Terminology 61,559 ( n =317, 55.1%). White blood cell counts peaked in the 12 to 18 months group, and were lowest in the 24± months group. Hematocrit was lowest in the 0 to 6 months group and rose steadily to the 24± months group; the inverse pattern was found in platelet concentration, which was highest in the youngest patients and lowest in the oldest. Prothrombin time, international normalized ratio, and partial thromboplastin time were relatively consistent across all age groups. Younger patients had significantly shorter operating room times, which increased with patient age ( P <0.001). Younger patients also had significantly shorter length of stay ( P =0.009), though length of stay peaked between 12 and 18 months. There was a significantly lower rate of surgical site infection in younger patients, which occurred in 0.7% of patients 0 to 12 months and 1.0 to 3.0% in patients over 12 to 24± months. There was no significant difference in the average number of transfusions required in any age group ( P =0.961).
