RESUMO

Traumatic optic neuropathy (TON) is a rare but potentially devastating complication of craniofacial trauma. Approximately half of patients with TON sustain permanent vision loss. In this study, we sought to identify the most common fracture patterns associated with TON. We performed a retrospective review of craniomaxillofacial CT scans of trauma patients who presented to the R Adams Cowley Shock Trauma Center from 2015 to 2017. Included were adult patients who had orbital fractures with or without other facial fractures. Patients diagnosed with TON by a formal ophthalmologic examination were analyzed. Craniofacial fracture patterns were identified. Bivariate analysis and multivariate logistic regression were performed to identify craniofacial fracture patterns most commonly associated with TON. A total of 574 patients with orbital fractures who met inclusion criteria [15 (2.6%)] were diagnosed with TON. The median [interquartile range (IQR)] age was 44 (28-59) years. Patients with optic canal fractures and sphenoid sinus fractures had greater odds of TON compared with patients who did not have these fracture types [adjusted odds ratio (aOR) 95% confidence interval (CI) 31.8 (2.6->100), 8.1 (2.7-24.4), respectively]. Patients who sustain optic canal and sphenoid sinus fractures in the setting of blunt facial trauma are at increased odds of having a TON. Surgeons and other physicians involved in the care of these patients should be aware of this association.

RESUMO

BACKGROUND: Although blunt cerebrovascular injury (BCVI) is recognized as a risk factor for trauma morbidity and mortality, little is described regarding similar cerebrovascular injury (CVI) in patients with penetrating wounds. The authors aim to characterize these injuries in the craniofacial self-inflicted gunshot wound (SIGSW) population. METHODS: An institutional review board (IRB)-approved retrospective nstudy was conducted on patients presenting to the R Adams Cowley Shock Trauma Center with SIGSWs between 2007 and 2016. All CVIs were categorized by location, type, and associated neurologic deficits. Demographic data, patient characteristics, additional studies, and long-term outcomes were collected. A multivariate analysis determining independent predictors of CVI in the SIGSW population was performed. RESULTS: Of the 73 patients with SIGSWs, 5 (6.8%) had CVIs separate from the bullet/cavitation tract (distant CVIs) and 9 had CVIs along the bullet/cavitation tract (in-tract CVIs). A total of 55.6% of in-tract and 40% of distant injuries were missed on initial radiology read. One distant CVI patient suffered a stroke during admission. The anterior to posterior gunshot wound trajectory was positively associated with distant CVIs when compared with no CVIs ( P  = 0.01). Vessel dissection was more prevalent in patients with distant CVIs, when compared against patients with in-tract CVIs ( P  = 0.02). CONCLUSIONS: Nearly 20% of craniofacial SIGSW patients have CVIs and 6.8% have BCVI-like injuries, which is 2-to-6-fold times higher than traditional BCVIs. Craniofacial SIGSWs serve as an independent screening criterion with comparable screening yields; the authors recommend radiographic screening for these patients with particular scrutiny for CVIs as they are frequently missed on initial radiographic interpretations.

RESUMO

INTRODUCTION: Self-inflicted gunshot wounds to the face frequently result in devastating injuries; however, there is a paucity of large experiences describing determinants of mortality and outcomes. METHODS: Using the National Trauma Databank from 2007 to 2015, patients suffering self-inflicted firearm facial injuries were included. RESULTS: Over 9 years 7869 patients were included: 87.7% were male, 46.4% suffered traumatic brain injury (TBI) and overall in-hospital mortality was 44.7%. The majority (67.8%) of in-hospital mortality occurred within the first 24 hours. Using multiple regression, advanced age (>65 years), presence of TBI, admission hypotension, and decreased Glasgow coma score were each independently associated with increased odds of mortality (all P < 0.001). Mandible or combined mandible/midface fracture injury patterns were most likely to survive (P < 0.001). Of those surviving to hospital discharge, the median [interquartile range] length of stay was 13 [6, 23] days, 86.6% required an intensive care unit stay with 67% requiring intubation and 42.5% tracheostomy. Among survivors, the combined mandible and midface fracture pattern resulted in the highest rates of tracheostomy (70.5%), gastrostomy tube placement (50.5%), and facial operations (87.0%) with a median [interquartile range] of 5 [3, 7] operative trips (all P < 0.001). CONCLUSIONS: Self-inflicted facial firearm injuries are highly morbid injuries with the majority of in-hospital deaths occurring the first hospital day. Differences including concomitant TBI, facial injury pattern, neurologic status, and presence of hypotension on admission were independently associated with survival/death. More extensive facial injuries (combined mandible and midface fracture patterns) were more likely to survive and required more intensive interventions.

RESUMO

Significant advances and increasing acceptance of vascularized composite allotransplantation (VCA) have contributed to emerging success of penile transplantation. The aims of penile transplantation are fourfold: adequate urinary function, enabling natural erections, restoration of erogenous sensation and appearance of external male genitalia. Successful penile transplantation also requires limiting risks and managing complications of lifelong immunosuppression. Given the limited experience with this procedure, potential recipients must understand that penile transplantation is not currently standard of care and long-term functional outcomes are unknown. Moreover, these transplants are associated with complex ethical issues. Nevertheless, as the efficacy and safety of penile transplantation are being evaluated, clear indications for transplant are needed. Although preliminary recommendations have been proposed, a more comprehensive framework is needed. We performed a literature review for English language publications related to penile transplantation and ethics. Based on the results of the search, a review of prior recommendations, and our experience performing the first whole male genital allotransplantation including penis, scrotum and abdominal wall; screening and identifying potential donors and recipients for the procedure; and addressing the associated ethical issues, we propose guidelines for responsible penile transplantation: The Baltimore Criteria for an Ethical Approach to Penile Transplantation.

RESUMO

The first uterus transplantation was performed in 2000. As key milestones are reached (long-lasting graft survival in 2011, and first birth from a transplanted womb in 2014), the ethical debate around uterus transplant evolves. We performed a systematic review of articles on uterus transplantation. Ethical themes were extracted and categorized according to four bioethical principles. Papers were divided into time periods separated by key events in uterus transplant history: Phase I (first technical achievement, 2002-2011), Phase II (clinical achievement, 2012-2014), and Phase III (after the first childbirth, 2015-2018). Eighty-one articles were included. The majority of ethics papers were published in Phase III (65%, P < 0.0001), that is after the first birth. Eighty percent of papers discussed nonmaleficence making it the most discussed principle. The first birth acted as a pivotal point: nonmaleficence was discussed by a lower proportion of articles (P = 0.0073), as was beneficence (P = 0.0309). However, discussion of justice increased to become the most discussed principle of the time period (P = 0.0085). The ethical debate surrounding uterus transplantation has evolved around landmark events that signify scientific progress. As safety and efficacy become evident, the focus of ethical debate shifts from clinical equipoise to socioeconomic challenges and equitable access to uterus transplantation.

RESUMO

PURPOSE: Self-inflicted facial gunshots (SIGSWs) typically result in a spectrum of severe injuries to facial structures, including the orbit and globe. Roughly three-quarters of those who arrive to the hospital will survive their injuries, and recidivism is typically low. Therefore, effective management is paramount to preserve vision, and long-term quality of life. The objective of this study is to characterize the common injuries to the orbit, globe, and periocular structures following SIGSWs, their management, and their eventual visual and reconstructive outcomes. METHODS: Retrospective review of trauma registry records at a Level 1 trauma center for patients who presented alive following SIGSWs involving the globe and/or orbit from 2007 to 2016. RESULTS: Of the 47 patients who presented with SIGSWs to the orbit, 33 (70%) were discharged alive from the hospital. Management strategies for these patients fell into 3 groups, based on the involved structures: i) Open globe injuries (Type I: n = 12, 34%) ii) Orbital fractures with preserved globe and optic nerve (Type II: n = 15, 43%), and iii) Optic nerve injuries with preserved globe (Type III: n = 8, 23%). Compared with Type II and III injuries, patients who had Type I injuries were more likely to die prior to hospital discharge (46% vs. 20% vs. 12%, p = 0.04), undergo ophthalmologic intervention (73% vs. 6% vs. 11%, p = 0.01), and more surgery (6 vs. 3 vs. 0.5 mean surgeries, p < 0.001). Type II injuries most frequently underwent debridement and reconstruction of the bony orbit. Type III and Type I injuries were associated with worse initial and final visual acuity, with the majority (100% and 75%, respectively) having No Light Perception (NLP) on initial exam, and no visual recovery during the follow-up period (median follow up= 25 months). CONCLUSIONS: Management and visual outcomes of orbital injuries from SIGSWs is determined by whether the globe and optic nerve are preserved. Open globe injury by itself is associated with higher mortality and significant permanent vision loss.

RESUMO

BACKGROUND: The purpose of this study was to characterize differences in facial fracture injury patterns among pediatric patients at highest risk of abusive head trauma/nonaccidental trauma (age ≤ 5 years). METHODS: Using the National Trauma Databank from 2007 to 2015, patients (age ≤ 5 years) suffering facial fractures were included. Demographics and injury characteristics were compared between those sustaining accidental versus nonaccidental trauma (NAT). RESULTS: Over 9 years 9741 patients were included with 193 patients (2.0%) suffering NAT. Nonaccidental trauma patients were younger (median [interquartile range]; 0 [0, 2] versus 3 [1, 4], P < 0.001), and more frequently were insured by Medicaid (76.7% versus 41.9%, P < 0.001). NAT patients were more likely to sustain mandible fractures (38.9% versus 21.1%, P < 0.001), but less likely to sustain maxilla (9.8% versus 18.3%, P = 0.003), or orbital fractures (31.1% versus 53.4%, P < 0.001). Nonaccidental trauma patients had fewer instances of multiple facial fracture sites (8.9% versus 22.6%, P < 0.001). Among those sustaining mandible fractures, NAT patients were more likely to sustain condylar fractures (75.8% versus 48.4%, P < 0.001), but less likely to sustain subcondylar fractures (0% versus 13.2%, P = 0.002), or angle fractures (1.6 versus 8.7%, P = 0.048). CONCLUSIONS: Differences exist in facial fracture patterns in accidental versus nonaccidental trauma within the pediatric population at highest risk for abusive head trauma. Specifically, NAT is associated with fractures of the mandibular condyle and involve fewer facial fracture sites. In the appropriate context, presence of these fractures/patterns should increase suspicion for NAT.

RESUMO

Panniculectomy can be performed as a prophylactic procedure preceding transplantation to enable obese patients to meet criteria for renal transplantation. No literature exists on combined renal transplant and panniculectomy surgery (LRT-PAN). We describe our 8-year experience performing LRT-PAN. A retrospective chart review of all patients who had undergone LRT-PAN from 2010 to 2018 was conducted. Data were collected on patient demographics, allograft survival and function, and postoperative course. Fifty-eight patients underwent LRT-PAN. All grafts survived, with acceptable function at 1 year. Median length of stay was 4 days with a mean operative duration of 363 minutes. The wound complication rate was 24%. Ninety-day readmission rate was 52%, with medical causes as the most common reason for readmission (45%), followed by wound (32%) and graft-related complications (23%). Body mass index, diabetes status, and previous immunosuppression did not influence wound complication rate or readmission (P = .7720, P = .0818, and P = .4830, respectively). Combining living donor renal transplant and panniculectomy using a multidisciplinary team may improve access to transplantation, particularly for the obese and postobese population. This combined approach yielded shorter-than-expected hospital stays and similar wound complication rates, and thus should be considered for patients in whom transplantation might otherwise be withheld on the basis of obesity.

RESUMO

BACKGROUND: Presentation of pediatric facial fractures varies widely and many injuries are encountered infrequently by most practitioners. This study summarizes injury patterns in a large cohort of facial fractures and their subsequent surgical management. METHODS: Demographic and clinical characteristics of patients 18 years of age or younger admitted between 2009 and 2015 to trauma centers participating in the National Trauma Data Bank were examined. Craniofacial fractures and reconstructive procedures performed at index admission were selected based on ICD-9 and AIS codes. A multivariable analysis was used to determine independent determinants of surgical repair. RESULTS: Out of 60,094 pediatric patients evaluated in the US emergency departments, 48,821 patients were admitted and underwent open treatment (n = 8364; 17.1%) or closed treatment (n = 4244; 8.7%) of facial fractures. Falls were the most common mechanism of injury in infants and toddlers (<2-year-old, 44.4%, P <0.001), while motor vehicle collisions (32.9%, P <0.001) and assault (22.1%, P <0.001) were most commonly seen in adolescents (12-18-year-old). The frequency and odds of repair of facial fractures increased with advancing age, more so with open than closed treatment in adolescents (73.0%) as compared to infants and toddlers (50.3%). Children who sustained mandible fractures are the most likely to require surgical treatment at index-admission (odds ratio = 13.9, 95% confidence interval 13.1-14.8, P <0.001). CONCLUSIONS: Population-based data shows that pediatric fracture patterns and associated early repair vary significantly with age. Patient demographics and hospital characteristics are significant determinants of surgical treatment that should be related to clinical outcomes in future studies.

RESUMO

Three-dimensional printing of patient-specific models is being used in various aspects of craniomaxillofacial reconstruction. Printing is typically outsourced to off-site vendors, with the main disadvantages being increased costs and time for production. Office-based 3-dimensional printing has been proposed as a means to reduce costs and delays, but remains largely underused because of the perception among surgeons that it is futuristic, highly technical, and prohibitively expensive. The goal of this report is to demonstrate the feasibility and ease of incorporating in-office 3-dimensional printing into the standard workflow for facial fracture repair.Patients with complex mandible fractures requiring open repair were identified. Open-source software was used to create virtual 3-dimensional skeletal models of the, initial injury pattern, and then the ideally reduced fractures based on preoperative computed tomography (CT) scan images. The virtual 3-dimensional skeletal models were then printed in our office using a commercially available 3-dimensional printer and bioplastic filament. The 3-dimensional skeletal models were used as templates to bend and shape titanium plates that were subsequently used for intraoperative fixation.Average print time was 6 hours. Excluding the 1-time cost of the 3-dimensional printer of $2500, roughly the cost of a single commercially produced model, the average material cost to print 1 model mandible was $4.30. Postoperative CT imaging demonstrated precise, predicted reduction in all patients.Office-based 3-dimensional printing of skeletal models can be routinely used in repair of facial fractures in an efficient and cost-effective manner.

RESUMO

To be effective for cytoplasmic delivery of therapeutics, nanoparticles (NPs) taken up via endocytic pathways must efficiently transport across the cell membrane and subsequently escape from the secondary endosomes. We hypothesized that the biomechanical and thermodynamic interactions of NPs with plasma and endosomal membrane lipids are involved in these processes. Using model plasma and endosomal lipid membranes, we compared the interactions of cationic NPs composed of poly(D,L-lactide-co-glycolide) modified with the dichain surfactant didodecyldimethylammonium bromide (DMAB) or the single-chain surfactant cetyltrimethylammonium bromide (CTAB) vs anionic unmodified NPs of similar size. We validated our hypothesis in doxorubicin-sensitive (MCF-7, with relatively fluid membranes) and resistant breast cancer cells (MCF-7/ADR, with rigid membranes). Despite their cationic surface charges, DMAB- and CTAB-modified NPs showed different patterns of biophysical interaction: DMAB-modified NPs induced bending of the model plasma membrane, whereas CTAB-modified NPs condensed the membrane, thereby resisted bending. Unmodified NPs showed no effects on bending. DMAB-modified NPs also induced thermodynamic instability of the model endosomal membrane, whereas CTAB-modified and unmodified NPs had no effect. Since bending of the plasma membrane and destabilization of the endosomal membrane are critical biophysical processes in NP cellular uptake and endosomal escape, respectively, we tested these NPs for cellular uptake and drug efficacy. Confocal imaging showed that in both sensitive and resistant cells DMAB-modified NPs exhibited greater cellular uptake and escape from endosomes than CTAB-modified or unmodified NPs. Further, paclitaxel-loaded DMAB-modified NPs induced greater cytotoxicity even in resistant cells than CTAB-modified or unmodified NPs or drug in solution, demonstrating the potential of DMAB-modified NPs to overcome the transport barrier in resistant cells. In conclusion, biomechanical interactions with membrane lipids are involved in cellular uptake and endosomal escape of NPs. Biophysical interaction studies could help us better understand the role of membrane lipids in cellular uptake and intracellular trafficking of NPs.

RESUMO

Facial buttresses are supportive bony structures of the facial skeleton that form a thick, strong, and protective framework for the face. Surgical fixation may be required to restore morphology and function when damage to these buttresses occurs. We sought to determine if, similar to buttresses of the facial skeleton, buttresses of the internal orbit exist. Hence, we analyzed 10 human cadaver skulls imaged by microcomputed tomography (micro-CT). Image processing and thickness/heat mapping were performed using Avizo and ImageJ softwares. After identifying the orbital buttresses, we reviewed CT scans of patients who had orbital fractures across three years to determine the frequency of fracture of the orbital buttresses. We identified 5 buttresses of the internal orbit: superomedial fronto-ethmoidal strut with the deep orbital buttress, inferomedial strut with the posterior ledge, inferior orbital fissure, sphenoid-frontal superolateral strut, and the sphenoid lip. The average threshold orbital buttress thickness was 1.36 (0.25) mm. A total of 1186 orbits of 593 individuals were analyzed for orbital buttress involvement. Orbital buttresses were spared in 770 (65%) orbits. The inferomedial strut with the posterior ledge was the most commonly fractured buttress in 14.4% of orbits (n=171), followed by the sphenoid strut and lip (66 [5.6%]). To our knowledge, this is the first description of the buttresses of the internal orbit. Orbital reconstruction for fracture repair or oncologic purposes requires the support of orbital buttresses. Understanding the anatomy of orbital buttresses is crucial for successful surgical planning, proper implant positioning, and restoration of function and appearance.

RESUMO

Intrathoracic fistulas present major challenges to reconstructive surgeons. Reconstruction with muscle flaps have been shown to improve patient outcomes; however, there are patients for whom one or more of the commonly used muscle flaps is not available for several reasons. We describe the use of an iliocostalis muscle rotational flap for the repair of a caudally located esophagopleural fistula in the setting of definitive chemoradiotherapy for treatment of nonsmall-cell lung cancer and reirradiation with photons for local recurrence 5 years later. Our repair remained intact through the nearly 12-month follow-up period during which the patient tolerated a regular diet. This report demonstrates that the iliocostalis lumborum muscle is a viable option for repair of intrathoracic fistulas that are located in the distal esophagus, even in the setting of previous thoracotomy and radiation, and should be part of the reconstructive surgeon's armamentarium in the management of intrathoracic fistulas.

RESUMO

ABSTRACT: The independent plastic surgery pathway recruits candidates with 5 years of surgical training who are typically more advanced in research than their integrated counterparts. Research productivity helps to discriminate between applicants. However, no studies exist detailing the academic attributes of matched independent plastic surgery candidates.We performed a cohort study of 161 independent plastic surgery fellows from accredited residency programs from the 2015 to 2017 application cycles. We performed a bibliometric analysis utilizing Scopus, PubMed, and Google Scholar to identify research output measures at the time of application.The cohort was predominantly men (66%) with a median of 3 articles and a H-index of 1 at the time of application. Interestingly, 16% of successful candidates had no published articles at the time of application, and this did not change significantly over time (P = .0740). Although the H-index remained stable (R 0.13, P = .1095), the number of published journal articles per candidate significantly decreased over 3 consecutive application cycles (R -0.16, P = .0484). Analysis of article types demonstrated a significant increase in basic science articles (R 0.18, P = .0366) and a concurrent decrease in editorial-type publications (R = -0.18, P = .0374).Despite the decline in publication volume of matched independent plastic surgery fellows, the quality of their research portfolio has remained constant. Matched applicants appear to be shifting focus from faster-to-publish articles to longer but higher impact projects. In selecting a training route, applicants must weigh the highly competitive integrated path against the dwindling number of independent positions.

RESUMO

BACKGROUND: Fractures of the orbital roof require high-energy trauma and have been linked to high rates of neurologic and ocular complications. However, there is a paucity of literature exploring the association between injury, management, and visual prognosis. METHODS: The authors performed a 3-year retrospective review of orbital roof fracture admissions to a Level I trauma center. Fracture displacement, comminution, and frontobasal type were ascertained from computed tomographic images. Pretreatment characteristics of operative orbital roof fractures were compared to those of nonoperative fractures. Risk factors for ophthalmologic complications were assessed using univariable/multivariable regression analyses. RESULTS: In total, 225 patients fulfilled the inclusion criteria. Fractures were most commonly nondisplaced [n = 118 (52.4 percent)] and/or of type II frontobasal pattern (linear vault involving) [n = 100 (48.5 percent)]. Eight patients underwent open reduction and internal fixation of their orbital roof fractures (14.0 percent of displaced fractures). All repairs took place within 10 days from injury. Traumatic optic neuropathy [n = 19 (12.3 percent)] and retrobulbar hematoma [n = 11 (7.1 percent)] were the most common ophthalmologic complications, and led to long-term visual impairment in 51.6 percent of cases. CONCLUSIONS: Most orbital roof fractures can be managed conservatively, with no patients in this cohort incurring long-term fracture-related complications or returning for secondary treatment. Early fracture treatment is safe and may be beneficial in patients with vertical dysmotility, globe malposition, and/or a defect surface area larger than 4 cm2. Ophthalmologic prognosis is generally favorable; however, traumatic optic neuropathy is major cause of worse visual outcome in this population. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

RESUMO

CASE REPORT: A 65-year-old Caucasian man presented with a debilitating anogenital lesion. DIFFERENTIAL DIAGNOSIS: The differential diagnosis of anogenital lesions includes infectious (syphilis, herpes simplex virus), noninfectious (hidradenitis suppuritiva, lymphedema), benign (condyloma acuminata), and malignant pathologies (squamous cell carcinoma, Kaposi sarcoma). DIAGNOSTIC ASSESSMENT, MANAGEMENT, AND OUTCOME: Biopsy of an anogenital lesion will determine any oncologic potential. Further imaging can better characterize the disease. Once in the operating room, oncologic principles should be adhered to and quality of life concerns prioritized. Reconstruction of large defects may require a multidisciplinary team. Genitourinary and gastrointestinal diversions should be considered to improve wound healing, decrease infection risk, and optimize graft take. DISCUSSION: A multidisciplinary approach to medical and surgical reconstruction of anogenital lesions should be considered for extensive malformations.

RESUMO

BACKGROUND: Following bariatric surgery, patients develop problems related to lax abdominal skin that may be addressed by contouring procedures. Third-party insurers have subjective requirements for coverage of these procedures that can limit patient access. The authors sought to determine how well third-party payers cover abdominal contouring procedures in this population. METHODS: The authors conducted a cross-sectional analysis of insurance policies for coverage of panniculectomy, lower back excision, and circumferential lipectomy. Abdominoplasty was evaluated as an alternative to panniculectomy. Insurance companies were selected based on their market share and state enrolment. A list of medical necessity criteria was abstracted from the policies that offered coverage. RESULTS: Of the 55 companies evaluated, 98 percent had a policy that covered panniculectomy versus 36 percent who would cover lower back excision (p < 0.0001), and one-third provided coverage for circumferential lipectomy. Of the insurers who covered panniculectomy, only 30 percent would also cover abdominoplasty. Documentation of secondary skin conditions was the most prevalent criterion in panniculectomy policies (100 percent), whereas impaired function and secondary skin conditions were most common for coverage of lower back excision (73 percent and 73 percent, respectively). Frequency of criteria for panniculectomy versus lower back excision differed most notably for (1) secondary skin conditions (100 percent versus 73 percent; p = 0.0030), (2) weight loss (45 percent versus 7 percent; p = 0.0106), and (3) duration of weight stability (82 percent versus 53 percent; p = 0.0415). CONCLUSIONS: For the postbariatric population, panniculectomy was covered more often and had more standardized criteria than lower back excision or circumferential lipectomy. However, all have vast intracompany and interpolicy variations in coverage criteria that may reduce access to procedures, even among patients with established indications.

RESUMO

BACKGROUND: Infections are challenging complications of implant-based breast reconstruction and augmentation. They pose a clinical challenge, with significant economic implications. One proposed solution is implant irrigation at the time of placement. There is no consensus on the optimal irrigant solution. METHODS: The authors tested the relative efficacy of 10% povidone-iodine, Clorpactin, Prontosan, triple-antibiotic solution, or normal saline (negative control) against two strains each of methicillin-resistant Staphylococcus aureus and Staphylococcus epidermidis. Sterile, smooth silicone implant disks were immersed in irrigant solution, then incubated in suspensions of methicillin-resistant S. aureus or S. epidermidis overnight. The disks were rinsed and sonicated to displace adherent bacteria from the implant surface, and the displaced bacteria were quantified. Normalized values were calculated to characterize the relative efficacy of each irrigant. RESULTS: Povidone-iodine resulted in reductions of the bacterial load by a factor of 10 to 10 for all strains. Prontosan-treated smooth breast implant disks had a 10-fold reduction in bacterial counts for all but one methicillin-resistant S. aureus strain. In comparison to Prontosan, triple-antibiotic solution demonstrated a trend of greater reduction in methicillin-resistant S. aureus bacterial load and weaker activity against S. epidermidis strains. Clorpactin reduced the recovered colony-forming units for only a single strain of S. epidermidis. Povidone-iodine demonstrated the greatest efficacy against all four strains. However, Clorpactin, triple-antibiotic solution, and Prontosan demonstrated similar efficacies. CONCLUSIONS: Povidone-iodine was the most efficacious of the irrigants at reducing methicillin-resistant S. aureus and S. epidermidis contamination. Given the recent lifting of the U.S. Food and Drug Administration moratorium, larger clinical studies of povidone-iodine as a breast implant irrigant solution are warranted. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, V.

RESUMO

Computed tomographic scans are frequently obtained following craniomaxillofacial fracture reconstruction. The additive radiation from such scans is not trivial; cumulative radiation exposure poses stochastic health risks. In this article, the authors postulate that a low-dose computed tomography protocol provides adequate image quality for postoperative evaluation of reconstructed craniomaxillofacial fractures. This study included patients for whom a computed tomographic scan was indicated following craniomaxillofacial fracture repair at a Level I trauma center. Postoperative craniomaxillofacial computed tomography was performed using a low-dose protocol, rather than standard protocols. A craniomaxillofacial surgeon and a radiologist interpreted the images to determine whether they were of sufficient quality. It was decided a priori that any inadequate low-dose computed tomography would require repeated scanning using standard protocols. The primary endpoint was the need for repeated computed tomography. In addition, the clarity of clinically significant anatomical landmarks on the images was graded on a five-point Likert scale. Twenty patients were scanned postoperatively using the low-dose protocol. Mean radiation dose (total dose-length product) from the low-dose protocol was 71 mGy · cm versus 532 mGy · cm for the preoperative computed tomographic scans that were obtained using conventional protocols (p < 0.001). All 20 low-dose computed tomographic scans were determined to provide satisfactory image quality. No patients required repeated computed tomography secondary to poor image quality. Low-dose computed tomography received high image-quality scores. A low-dose computed tomography protocol that delivers approximately 7.5-fold less radiation than the standard protocols was found to be adequate for postoperative evaluation of craniomaxillofacial fractures. Larger prospective studies may be warranted. CLINICAL QUESTION/LEVEL OF EVIDENCE:: Therapeutic, IV.

RESUMO

BACKGROUND: Plastic surgery continues to be one of the most competitive specialties in the residency match. Research productivity is a key component of the selection process. Nevertheless, potential applicants have a poor understanding of the strength of their research credentials in comparison to other applicants. METHODS: The authors identified successful applicants from the 2012 to 2017 integrated plastic surgery residency application cycles. The authors performed a bibliometric analysis of these residents using Scopus, PubMed, and Google Scholar to identify published articles at the time of application. The authors then calculated the h-index of each applicant at the time of application. RESULTS: The authors included 829 integrated residents. The median h-index was 0 (interquartile range, 0 to 3) and the median number of publications was 2 (interquartile range, 0 to 5) for all applicants. The proportion of applicants with at least one publication at the point of application increased significantly over time (60 percent in 2012 versus 76 percent in 2017; p = 0.0072). In addition, the number of publications per applicant increased over time (one in 2012 versus two in 2017; p = 0.0005), as did h-index (0 in 2012 versus 1 in 2017; p = 0.0015). Strikingly, the number and percentage of review articles among applicants increased significantly over this time frame (9 percent versus 14 percent; p = 0.0299). CONCLUSIONS: The increasing level of academic productivity among applicants may reflect the increasing competitiveness of the integrated plastic surgery residency application process. As the pressure to compete for a training position increases, students may seek faster-to-publish articles to gain an edge.
