Abstract
Osteosarcomas arising within the pterygomaxillary/infratemporal fossa region are rare among the pediatric population. Survival rates are most influenced by tumor resection with negative margins, which can be dependent on surgical accessibility of the tumor site. The pterygomaxillary/infratemporal fossa location poses several challenges to safe and adequate tumor resection, including proximity of the facial nerve and great vessels and scarring associated with traditional transfacial approaches. In this article, we present the case of a 6-year-old boy with an osteosarcoma of the left pterygomaxillary/infratemporal fossa region successfully managed with an "oncoplastic" approach, incorporating the use of CAD/CAM and mixed reality technologies.

Lessons Learned from a Single Institution's Eight Years of Experience with Early Cleft Lip Repair. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1741. [PMID: 37893459 PMCID: PMC10608426 DOI: 10.3390/medicina59101741] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/26/2023] [Revised: 09/19/2023] [Accepted: 09/21/2023] [Indexed: 10/29/2023]
Abstract
Background and Objectives: The traditional approach in managing wide cleft lip deformities involves presurgical nasoalveolar molding (NAM) therapy followed by surgical cleft lip repair between three and six months of age. This institution has implemented an early cleft lip repair (ECLR) protocol where infants undergo primary cleft lip repair between two and five weeks of age without NAM. This study aims to present this institution's ECLR repair protocol over the past eight years from 188 consecutive patients with unilateral or bilateral CL/P deformity. Materials and Methods: Retrospective review was conducted at Children's Hospital Los Angeles evaluating patients who underwent ECLR before three months of age and were classified as American Society of Anesthesiologists (ASA) class I or II from 2015-2022. Anthropometric analysis was performed, and pre- and postoperative photographs were evaluated to assess nasal and lip symmetry. Results: The average age at cleft lip repair after correcting for gestational age was 1.0 ± 0.5 months. Mean operative and anesthetic times were 120.3 ± 33.0 min and 189.4 ± 35.4, respectively. Only 2.1% (4/188) of patients had postoperative complications. Lip revision rates were 11.4% (20/175) and 15.4% (2/13) for unilateral and bilateral repairs, respectively, most of which were minor in severity (16/22, 72.7%). Postoperative anthropometric measurements demonstrated significant improvements in nasal and lip symmetry (p < 0.001). Conclusions: This analysis demonstrates the safety and efficacy of ECLR in correcting all unilateral cleft lip and nasal deformities of patients who were ASA classes I or II. At this institution, ECLR has minimized the need for NAM, which is now reserved for patients with bilateral cleft lip, late presentation, or comorbidities that preclude them from early repair. ECLR serves as a valuable option for patients with a wide range of cleft severity while reducing the burden of care.

Abstract
INTRODUCTION Vertical Orbital Dystopia (VOD) results in significant facial asymmetry, psychological distress, and poor quality of life in affected patients. The traditional approach (TA) for surgical correction has entailed a standard frontal craniotomy along with circumferential orbital osteotomy, vertical translocation of the orbit, and bone grafting to the lower maxilla. Caution has been expressed regarding its invasive transcranial nature. In this report, we describe the limited approach (LA) for simplified surgical correction of VOD, which obviates the need for a standard frontal craniotomy. METHODS A 45-year retrospective review was conducted of all patients that underwent surgical correction of VOD, as performed by a single surgeon. Demographic details, procedural characteristics, and complications were compared between patients who were corrected by the TA and those who were corrected by the LA. Complications were defined as CSF leak, infection of the frontal bone, permanent diplopia, permanent ptosis, sudden-onset vision loss, persistent asymmetry, and surgical revision. RESULTS Forty patients met inclusion criteria for correction of true VOD, of which 18 underwent the TA and 22 underwent the LA. Mean length of hospital stay was 5.3±2.3 days and 4.0±1.5 days for the TA and LA cohorts, respectively. Mean follow-up time was 4.9±7.5 years for the TA and 2.6±3.3 years for the LA. The only reported complications were persistent asymmetry in 2 patients in the TA cohort with one patient requiring surgical revision due to undercorrection, while the LA cohort exhibited no postoperative asymmetry or need for surgical revision. CONCLUSIONS Both the TA and LA are effective for surgical correction of VOD. The limited craniotomy of the LA reduces exposure of intracranial structures and adequately achieves postoperative symmetry.

De novo variants implicate chromatin modification, transcriptional regulation, and retinoic acid signaling in syndromic craniosynostosis. Am J Hum Genet 2023; 110:846-862. [PMID: 37086723 PMCID: PMC10183468 DOI: 10.1016/j.ajhg.2023.03.017] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2022] [Accepted: 03/24/2023] [Indexed: 04/24/2023] Open
Abstract
Craniosynostosis (CS) is the most common congenital cranial anomaly. Several Mendelian forms of syndromic CS are well described, but a genetic etiology remains elusive in a substantial fraction of probands. Analysis of exome sequence data from 526 proband-parent trios with syndromic CS identified a marked excess (observed 98, expected 33, p = 4.83 × 10-20) of damaging de novo variants (DNVs) in genes highly intolerant to loss-of-function variation (probability of LoF intolerance > 0.9). 30 probands harbored damaging DNVs in 21 genes that were not previously implicated in CS but are involved in chromatin modification and remodeling (4.7-fold enrichment, p = 1.1 × 10-11). 17 genes had multiple damaging DNVs, and 13 genes (CDK13, NFIX, ADNP, KMT5B, SON, ARID1B, CASK, CHD7, MED13L, PSMD12, POLR2A, CHD3, and SETBP1) surpassed thresholds for genome-wide significance. A recurrent gain-of-function DNV in the retinoic acid receptor alpha (RARA; c.865G>A [p.Gly289Arg]) was identified in two probands with similar CS phenotypes. CS risk genes overlap with those identified for autism and other neurodevelopmental disorders, are highly expressed in cranial neural crest cells, and converge in networks that regulate chromatin modification, gene transcription, and osteoblast differentiation. Our results identify several CS loci and have major implications for genetic testing and counseling.

A characterization of home maintenance equipment-related hand and lower arm injuries. J Clin Orthop Trauma 2022; 31:101943. [PMID: 35844978 PMCID: PMC9278494 DOI: 10.1016/j.jcot.2022.101943] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/01/2021] [Revised: 11/23/2021] [Accepted: 07/01/2022] [Indexed: 11/30/2022] Open
Abstract
BACKGROUND Thousands of Americans sustain injuries from various household appliances each year, though injury patterns have not been well characterized. We thus sought to determine the incidence, characteristics, and trends of household appliance-related hand injuries over the past decade. METHODS The National Electronic Injury Surveillance System database (NEISS) was queried from 2010 through 2019. Our analysis grouped patients into 10-year age groups. We defined types of appliances and injuries Chi-square tests were used to compare the most common injury mechanisms by age group. RESULTS Between 2010 and 2019, 30,336 total cases of home workshop equipment-related upper extremity injuries were recorded; 2,574 (8.48%) of these affected females, compared to 27,762 (91.52%) of the cases affecting males. Across all age groups, males were between 6 and 13 more times likely to be injured than females (p < 0.001). Between 2010 and 2019, we recorded a decline in total injuries from 168,795 to 147,584, with a Pearson correlation coefficient of -0.68 (p = 0.031). The appliances most likely to injure those in their 10s through 40s were mechanical tools such as screwdrivers. Meanwhile, those in their 50s through 70s were most likely to be injured by saws. Both amputations and avulsions were found to significantly increase with age (p = 0.038, p = 0.027, respectively). Most injuries result from manual tools and saws. DISCUSSION Males are significantly more likely to incur injuries than females from maintenance equipment, and risk of avulsions and amputations increase significantly with age. This aligns with previous research which also suggested that older saws were most likely to injure older individuals; namely, following new regulations on saws, older adults were more likely to be affected. This is especially worrisome in light of recent research showing that older adults with amputations are less likely to be offered replantations. Overall, these results can continue to guide and optimize community interventions on an epidemiological basis.

Abstract
Human amniotic membrane (hAM) and collagen nerve wraps are biomaterials that have been investigated as therapies for improving outcomes of peripheral nerve regeneration; however, their efficacy has not been compared. The purpose of this study is to compare the efficacy of collagen and human amniotic membrane nerve wraps in a rodent sciatic nerve reverse autograft model. Lewis rats (n = 29) underwent sciatic nerve injury and repair in which a 10-mm gap was bridged with reverse autograft combined with either no nerve wrap (control), collagen nerve wrap or hAM nerve wrap. Behavioral analyses were performed at baseline and 4, 8 and 12 weeks. Electrophysiological studies were conducted at 8, 10 and 12 weeks. Additional outcomes assessed included gastrocnemius muscle weights, nerve adhesions, axonal regeneration and scarring at 12 weeks. Application of both collagen and hAM nerve wraps resulted in improvement of functional and histologic outcomes when compared with controls, with a greater magnitude of improvement for the experimental group treated with hAM nerve wraps. hAM-treated animals had significantly higher numbers of axons compared to control animals (p < 0.05) and significantly less perineural fibrosis than both control and collagen treated nerves (p < 0.05). The ratio of experimental to control gastrocnemius weights was significantly greater in hAM compared to control samples (p < 0.05). We conclude that hAM nerve wraps are a promising biomaterial that is effective for improving outcomes of peripheral nerve regeneration, resulting in superior nerve regeneration and functional recovery compared to collagen nerve wraps and controls.

Abstract
Abstract
Media attention has in recent years created an increased patient demand for gluteal contouring and augmentation. Gluteal augmentation and contouring with autologous fat transfer, colloquially referred to as the “Brazilian butt lift” (BBL), can be performed safely and effectively, with an overall complication rate ranging from 1.5% to 6.8%. However, there have been an alarming number of lethal events from intravenous passage of injected fat and fatal pulmonary embolism due to macro-fat emboli (MAFE). MAFE (fat emboli >1 cm in diameter), distinct from micro-fat emboli, can quickly result in catastrophic cardiopulmonary compromise and death. Accurate mortality estimates are limited by difficulties in determining accurate values for the total number of BBL procedures performed because most of these cases are performed at budget clinics. Accurate morbidity estimates are limited by a lack of published outcomes and a low level of evidence in published studies. The first case of survival of MAFE secondary to BBL was reported in 2019 by Peña et al. Few highly morbid complications secondary to MAFE have been reported because such events are almost universally lethal. We present 2 recent cases of survival after MAFE in the setting of gluteal fat transfer following expedient transfer to a tertiary care setting, allowing for timely and successful intervention. We illustrate examples of how MAFE is a highly lethal complication of gluteal fat grafting. Early recognition and immediate aggressive vital support to stabilize the patient are key for survival.

Abstract
INTRODUCTION Collagen and human amniotic membrane (hAM) are Food and Drug Administration (FDA)-approved biomaterials that can be used as nerve wraps or conduits for repair of peripheral nerve injuries. Both biomaterials have been shown to reduce scarring and fibrosis of injured peripheral nerves. However, comparative advantages and disadvantages have not been definitively shown in the literature. The purpose of this systematic review is to comprehensively evaluate the literature regarding the roles of hAM and collagen nerve wraps and conduits on peripheral nerve regeneration in preclinical models. METHODS The MEDLINE database was queried using the PubMed search engine on July 7, 2019, with the following search strategy: ("amniotic membrane" OR "amnion") OR ("collagen conduit" OR "nerve wrap")] AND "nerve." All resulting articles were screened by two independent reviewers. Nerve type, lesion type/injury model, repair type, treatment, and outcomes were assessed. RESULTS Two hundred and fifty-eight articles were identified, and 44 studies remained after application of inclusion and exclusion criteria. Seventeen studies utilized hAM, whereas 27 studies utilized collagen wraps or conduits. Twenty-three (85%) of the collagen studies utilized conduits, and four (15%) utilized wraps. Six (35%) of the hAM studies utilized conduits and 11 (65%) utilized wraps. Two (9%) collagen studies involving a conduit and one (25%) involving a wrap demonstrated at least one significant improvement in outcomes compared with a control. While none of the hAM conduit studies showed significant improvements, eight (73%) of the studies investigating hAM wraps showed at least one significant improvement in outcomes. CONCLUSION The majority of studies reported positive outcomes, indicating that collagen and hAM nerve wraps and conduits both have the potential to enhance peripheral nerve regeneration. However, relatively few studies reported significant findings, except for studies evaluating hAM wraps. Preclinical models may help guide clinical practice regarding applications of these biomaterials in peripheral nerve repair.

Abstract
BACKGROUND Short instructional videos can make learning more efficient through the application of multimedia principles, and video animations can illustrate the complex concepts and dynamic processes that are common in health sciences education. Commercially produced videos are commonly used by medical students but are rarely integrated into curricula. OBJECTIVE Our goal was to examine student engagement with medical education videos incorporated into a preclinical Cardiovascular Systems course. METHODS Students who took the first-year 8-week Cardiovascular Systems course in 2019 and 2020 were included in the study. Videos from Osmosis were recommended to be watched before live sessions throughout the course. Video use was monitored through dashboards, and course credit was given for watching videos. All students were emailed electronic surveys after the final exam asking about the course's blended learning experience and use of videos. Osmosis usage data for number of video views, multiple choice questions, and flashcards were extracted from Osmosis dashboards. RESULTS Overall, 232/359 (64.6%) students completed surveys, with rates by class of 81/154 (52.6%) for MD Class of 2022, 39/50 (78%) for MD/MPH Class of 2022, and 112/155 (72.3%) for MD Class of 2023. Osmosis dashboard data were available for all 359 students. All students received the full credit offered for Osmosis engagement, and learning analytics demonstrated regular usage of videos and other digital platform features. Survey responses indicated that most students found Osmosis videos to be helpful for learning (204/232, 87.9%; P=.001) and preferred Osmosis videos to the traditional lecture format (134/232, 57.8%; P<.001). CONCLUSIONS Commercial medical education videos may enhance curriculum with low faculty effort and improve students' learning experiences. Findings from our experience at one medical school can guide the effective use of supplemental digital resources for learning, and related evaluation and research.

Abstract
BACKGROUND Facial transplantation is a complex surgical procedure that requires education of medical professionals, patients, and the general public. The objective of this randomized controlled trial was to compare the educational efficacy of facial transplantation digital animation versus text resources for teaching medical students a complex surgical procedure and its applicable anatomical and surgical principles. METHODS Medical student volunteers were recruited and prospectively randomized to an animation or a text group. Students completed preintervention and postintervention assessments of confidence and knowledge of head and neck anatomy and facial transplantation. Student Evaluations of Educational Quality survey assessed student satisfaction with both tools following study crossover. Knowledge assessment was developed using National Board of Medical Examiners guidelines and content validated by four experts. The Cohen d statistic was used to measure the effect size of each intervention. RESULTS Thirty-six students were assigned randomly to the animation group (n = 19) or the text (n = 17) group. Postintervention analysis demonstrated significantly higher performance scores in the animation group compared to the text group (p = 0.029). The animation group had a larger effect size (Cohen d = 1.96 versus 1.27). Only students in the animation group reported significantly improved confidence in head and neck anatomy after the intervention (p = 0.002). Both groups demonstrated significantly increased postintervention confidence in knowledge of facial transplantation (p < 0.001). Satisfaction scores revealed that students significantly favored the animation resource (p < 0.001). CONCLUSIONS Animation can be an effective tool for facial transplantation education and results in improved student knowledge, confidence, and satisfaction compared to text resources. Facial transplantation can also be used as an educational framework for teaching medical students anatomical and surgical principles.

Abstract
INTRODUCTION Soccer is a global sport played by millions annually with an increasing popularity in the United States. Game is played by a wide range of participants from all ages and levels of competition. This scenario leads to a potential disparity in the injury profile based on quantifiable demographics. As the game continues to grow, injury detection and side-line assessment must change as well. METHODS Utilizing a national injury database, a retrospective cohort study was conducted using 10 years of data collected from randomly selected emergency departments across the United States. Patient demographics, injury sites, and diagnosis were recorded. Diagnoses examined included concussion, contusion or abrasion, dental injury, fracture, hematoma, hemorrhage, internal injury, and laceration. RESULTS Highest percentage of craniofacial injuries was observed in soccer players between the ages of 12 and 18. In ages 6 to 11 the most common injuries were contusions and dental injuries, with a significantly low number of fractures. Within the age group of 12 to 18 the highest percentage of injuries was concussions. Finally, the highest percentage of injury in the ages of 19 to 34 were fractures and lacerations. DISCUSSION There is a shift in injury profile as the age of soccer players increases and the level of play becomes faster-paced. In youth players, there is a higher percentage of soft tissue injury. Older players are more likely to suffer a higher degree of injury including fractures, concussions, and lacerations. This suggests a great utility for a layperson-friendly educational intervention initiative applicable to all demographics for the sport of soccer.

Abstract
Frontonasal dysplasia (FND) is a rare congenital craniofacial cleft syndrome associated with a spectrum of midline facial bone and soft-tissue malformations. When present, the physical features of FND are often obvious and classified at birth. The resultant facial deformities have the potential to negatively influence psychosocial health and quality of life. Reconstructive surgical intervention in early childhood can serve to restore facial contour and alleviate psychological stress. In this report, a case of a 14-year-old female with previously undiagnosed mild form of FND presented for reconstructive surgery evaluation and underwent several procedures including sliding advanced genioplasty, submucosal resection of the nasal turbinates, open rhinoplasty, and bilateral transnasal medial canthopexies. The patient had subsequent nasal tip recontouring for persistent supratip fullness. The patient achieved an acceptable esthetic outcome and was satisfied with her physical appearance. This case emphasizes the subtle presentation and reconstructive surgical options of a mild case of FND that was diagnosed at a later age, unlike the more severe phenotypes of the syndrome and other common craniofacial anomalies that are usually diagnosed and treated in early childhood. Multidisciplinary craniofacial care teams should be able to correctly diagnose and implement the appropriate surgical interventions in patients with milder forms of FND.

Abstract
Sturge Weber Syndrome is characterized by the classic triad of a facial port-wine stain, leptomeningeal angiomatosis, and glaucoma. The resultant facial vascular anomaly can lead to soft tissue and bone irregularities, causing psychosocial distress and mental health morbidity. When severe, patients can opt for multi-staged surgical intervention by reconstructive surgeons to restore normal symmetry and improve the aesthetic appearance of the face. This study reports a case of surgical correction for severe facial vascular malformation resulting in poor outcomes due to the associated mental comorbidities seen in Sturge Weber Syndrome. A 37-year-old male with previously diagnosed Sturge Weber Syndrome presented to the outpatient craniofacial clinic for surgical evaluation of a large facial tuberous hemangioma. The patient underwent multiple operations for facial reconstruction including a staged full-thickness skin graft, facial recontouring, and extracranial correction of vertical orbital dystopia. The case was complicated by the patient's poorly controlled seizure disorder and psychosocial illness, resulting in self-mutilation of the repair and poor follow-up. Over the span of 10 years, the patient's mental illness caused him to fail numerous attempts at facial restoration and ultimately led to a poor final result. The psychosocial distress seen in patients with Sturge Weber Syndrome can adversely affect surgical outcomes. Physicians should be mindful of the possible complications that can arise in these patients and have the clinical means to address them.

Abstract
BACKGROUND Skin color matching is an essential factor in achieving optimal aesthetic outcome in partial facial transplantation. However, there is no published literature evaluating the success of color matching to date. Furthermore, a medical professional's perception of an optimal color match may not necessarily translate to that of the general public. The purpose of our study was to evaluate skin color matching between the donor allograft and recipient native tissue in partial facial transplantations to determine the level of success perceived by the general public and medical professionals. METHODS Published photographs of partial face transplant recipients were used to create a survey where recipient native and donor allograft skin samples were juxtaposed. Thirty-three members of the general public and 30 medical professionals were asked to rate skin color match on a scale from "excellent match" to "not a match." RESULTS Overall, 47% of given ratings were positive, indicating an "excellent" or "good match," and 53% of ratings were negative, indicating a "poor match" or "lack of match" between the skin sample pairings shown. Of the 19 partial face transplant patients who were rated, 9 patients received >50% positive ratings, and 10 patients received <50% positive ratings. Medical professionals consistently gave more positive ratings, with statistically significant differences in 7 of the 19 rated patients (P < 0.05). CONCLUSION The results suggest that there is need for improvement in color matching in partial facial transplantation, and that the general public is more critical of skin color matching compared to medical professionals.

Abstract
Presence of a cervical rib results from overdevelopment of the seventh cervical vertebrae.1-3 The cervical rib along with scalene muscles can cause neurogenic thoracic outlet syndrome.4,5 Rib resection is typically done via anterior approach, using either supraclavicular or transaxillary route.6,7 We present an operative video detailing supraclavicular resection of a cervical rib causing neurogenic thoracic outlet syndrome with direct decompression of the lower trunk of the brachial plexus. The patient presented with severe symptoms including hand atrophy. We were able to directly visualize the rib and resect it, along with scalene musculature. We present 3-mo follow-up data noting clinical improvement in neuropathic symptoms.

Abstract
PURPOSE Nerve transfers for peripheral nerve injuries can result in variable outcomes. We investigated the neuroprotective effect of epineurial lidocaine injection in the donor nerve prior to transection, with the hypothesis that proximal axon loss would be decreased with consequent increased neuroregeneration and functional recovery. METHODS A rat sciatic nerve model was used with 4 intervention groups: (1) lidocaine; (2) lidocaine/calcium gluconate (CG); (3) CG; or (4) saline (control). Behavioral testing and qualitative and quantitative histological evaluation was performed at 8 and 12 weeks. Histological assays included transmission electron microscopy, retrograde fluorogold labeling, and whole mount immunostaining. RESULTS Functional assessments through the sciatic functional index and Basso, Beattie, and Bresnahan scale showed a statistically significant increase in recovery at 8 and 12 weeks with lidocaine treatment. Significantly higher axonal counts were obtained in the lidocaine-treated groups. Fragmentation and increased myelin damage was present in the CG and saline groups. Retrograde fluorogold labeling showed a statistically significant increase in the number of L4-6 dorsal root ganglion neurons in the lidocaine-treated groups. Whole mount immunostaining identified extension of the axonal growth cone past the nerve coaptation site in lidocaine-treated groups, but not in CG and saline groups. CONCLUSIONS Our results suggest that epineurial lidocaine injection prior to donor nerve transection for nerve transfer has a neuroprotective effect, resulting in increased proximal axon counts and improved functional recovery. CLINICAL RELEVANCE These findings may have direct clinical application because epineurial lidocaine can be used in surgery as a simple and inexpensive intervention for promoting improved clinical outcomes after nerve transfer.

Abstract
Preimplantation genetic diagnosis (PGD) is a form of prenatal diagnosis applied to potential parents with known carrier status of a genetic disease, such as Huntington disease. It employs the use of polymerase chain reaction to amplify single cells from early embryos obtained with in vitro fertilization (IVF) techniques. PGD allows the couple the chance to have a pregnancy and livebirth child without Huntington disease, although there are some risks and expenses related to the procedures. Success of the procedure may be greater than standard IVF because the patients are not infertility patients, but are undergoing the procedure to avoid passing a highly deleterious disease gene to offspring. Recent advances in sequencing may allow for higher success rates as the chromosomally abnormal embryos will be identified more easily and the embryos with the highest chance of survival will be transferred.
