RESUMO
PURPOSE: To address patient health literacy, the American Medical Association and the National Institutes of Health recommend that readability of patient education materials should not exceed an eighth grade reading level. However, patient-facing materials often remain above the recommended average reading level. Current online calculators provide readability scores; however, they lack the ability to provide text-specific feedback, which may streamline the process of simplifying patient materials. The purpose of this study was to evaluate Chat Generative Pretrained Transformer (ChatGPT) 3.5 as a tool for optimizing patient-facing hand surgery education materials through reading level analysis and simplification. METHODS: The readability of 18 patient-facing hand surgery education materials was compared by a traditional online calculator for reading level and ChatGPT 3.5. The original excerpts were then entered into ChatGPT 3.5 and simplified by the artificial intelligence tool. The simplified excerpts were scored by the same calculators. RESULTS: The readability scores for the original excerpts from the online calculator and ChatGPT 3.5 were similar. The simplified excerpts' scores were lower than the originals, with a mean of 7.28, less than the maximum recommended 8. CONCLUSIONS: The use of ChatGPT 3.5 for the purpose of simplification and readability analysis of patient-facing hand surgery materials is efficient and may help facilitate the conveyance of important health information. ChatGPT 3.5 rendered readability scores comparable with traditional readability calculators, in addition to excerpt-specific feedback. It was also able to simplify materials to the recommended grade levels. CLINICAL RELEVANCE: By confirming ChatGPT3.5's ability to assess and simplify patient education materials, this study offers a practical solution for potentially improving patient comprehension, engagement, and health outcomes in clinical settings.
RESUMO
Mandibular distraction has variable outcomes in Treacher-Collins syndrome. Dual syndromic diagnosis is a rare occurrence that complicates management. Here, the authors present a patient with Treacher-Collins syndrome and severe retrognathia requiring tracheostomy who failed repeat mandibular distraction and decannulation. A genetic workup later revealed Angelman syndrome with severe developmental delay. We discuss explanations for difficulties encountered during mandibular distraction as well as surgical options for patients with Treacher-Collins who fail multiple attempts at decannulation. Overall, patients with dual diagnoses can exhibit an underlying problem in bone formation and mineralization, which challenges any attempt at craniofacial manipulation.
RESUMO
OBJECTIVE: To assess the effectiveness of an interactive iPad-based educational module (cleft iBook) in enhancing parent/caregiver education related to cleft lip and/or cleft palate (CL/P) care. DESIGN: A prospective study involving pre- and post-intervention surveys. SETTING: The study was conducted at a craniofacial clinic in a dedicated children's hospital specifically during initial consultations for CL/P care. PARTICIPANTS: Thirty-two participants (parents/legal guardians/caregivers) ≥18 years of age, English and/or Spanish-speaking, and attending with a child with CL/P. INTERVENTIONS: Participants were provided with iPads and engaged with the interactive iPad-based educational module. Pre- and post-intervention surveys were administered. MAIN OUTCOME MEASURE(S): The survey assessed the understanding of a CL/P diagnosis and management and usability of the iBook. Survey responses were graded on a 5-point Likert scale. Total scores for pre- and post-intervention surveys were compared. RESULTS: Utilizing the cleft iBook module before consultation significantly enhanced comprehension in multiple domains: prenatal development of CL/P, dento-facial molding, surgical techniques, steps after the initial consultation, postoperative care, and the necessity of long-term care for affected children (P < .01). Cumulative survey scores increased by 10.2 points, reflecting significantly improved responses regarding overall comprehension (P < .001). CONCLUSIONS: The interactive, iPad-based cleft educational module emerges as a viable, digital strategy for providing education and empowerment to parents and caregivers navigating the challenges of caring for a child with CL/P. The cleft iBook serves as a readily accessible resource, fostering connections among the child, caregivers, and care team.
RESUMO
OBJECTIVE: The inaugural Cleft Summit aimed to unite experts and foster interdisciplinary collaboration, seeking a collective understanding of velopharyngeal insufficiency (VPI) management. DESIGN: An interactive debate and conversation between a multidisciplinary cleft care team on VPI management. SETTING: A two-hour discussion within a four-day comprehensive cleft care workshop (CCCW). PARTICIPANTS: Thirty-two global leaders from various cleft disciplines. INTERVENTIONS: Cleft Summit that allows for meaningful interdisciplinary collaboration and knowledge exchange. MAIN OUTCOME MEASURES: Ability to reach consensus on a unified statement for VPI management. RESULTS: Participants agreed that a patient with significant VPI and a dynamic velum should first receive a surgery that lengthens the velum to optimize patient outcome. A global, multicenter prospective study should be done to test this hypothesis. CONCLUSION: The 1st Cleft Summit successfully distilled global expertise into actionable best-practice guidelines through iterative discussions, fostering interdisciplinary collaboration and paving the way for a transformative multi-center prospective study on VPI care.
RESUMO
This study aims to characterize current use, knowledge, and attitude toward ERAS protocols by academic craniofacial surgeons.Craniofacial surgeons were provided with electronic surveys.Electronic survey; Institutional tertiary surgeons.102 cleft palate surgeons surveyed and 31 completed the survey (30.4%).None.Respondents rated their knowledge, use, and willingness to implement perioperative interventions modeled after adult ERAS protocols.Majority (67.7%) rated they were knowledgeable about ERAS. However, 61.3% "never use" a standardized protocol for cleft palate surgery. Only 3 ERAS elements are currently implemented by a majority of cleft surgeons: avoiding prolonged perioperative fasting (67.7%), using hypothermia prevention measures (74.2%), and minimizing use of opioids (62.5%). A large majority of respondents noted they never administer bolus (71.0%) or infusion (80.6%) dosing of tranexamic acid; most of these surgeons also indicated that administering tranexamic acid "would not be a valuable addition" (67.7% and 71.0%, respectively). Short-acting sedatives are used by 12.9% and by 16.1% of surgeons in all patients during extubation and postoperative recovery, respectively. By contrast, 22.6% never use such agents during extubation and 48.4% never use it during postoperative recovery. Overall, 67.7% of respondents replied that they would be willing to implement an ERAS protocol for cleft palate repair.Many respondents report using interventions compatible with an ERAS approach and the majority are willing to implement an ERAS protocol for cleft palate repair.

Musculoskeletal (MSK) injuries are the most common and debilitating work-related injuries among healthcare providers. These injuries often occur due to a lack of awareness and insufficient guidance during the early years of medical training. Recognizing the need to address this issue, the Comprehensive Cleft Care Workshop (CCCW) has taken steps to integrate an ergonomics session into its curriculum. The goal of this initiative is to enhance awareness on ergonomics, improve the integration of ergonomics into daily routine, and ultimately reduce the occurrence of MSK injuries among healthcare professionals.
RESUMO
INTRODUCTION: Clefts of the lip are of the most common congenital craniofacial anomalies. The development and implementation of an enhanced recovery after surgery (ERAS) protocol among patients undergoing cleft lip repair may decrease postoperative complications, accelerate recovery, and result in earlier postoperative discharge. METHODS: A modified ERAS program was developed and applied through Global Smile Foundation outreach craniofacial programs. The main components of this protocol include: (1) preoperative patient education, (2) nutrition screening, (3) smoking cessation when applicable, (4) use of topical anesthetic adjuncts, (5) facial nerve blocks, (6) postoperative analgesia, (7) preferential use of short-acting narcotics, (8) antibiotic administration, (9) use of elbow restraints, (10) early postoperative oral feeding and hydration, and (11) discharge planning. RESULTS: Between April 2019 and March 2020, GSF operated on 126 patients with cleft lip from different age groups and 58.8% of them were less than 1 year of age. Three patients (2.4%) had delayed wound healing and one (0.8%) had postoperative bleeding. There were no cases of mortality, length of hospital stay did not exceed 1 postoperative day, and patients were able to tolerate fluids intake at discharge. CONCLUSION: The implementation of an ERAS protocol among patients undergoing cleft lip repair has shown to be highly effective in minimizing postoperative discomfort while reducing opioids use, decreasing the length of stay in hospital, and leading to early oral feeding resumption. The ERAS principles described carry increased relevance in the context of the ongoing COVID-19 pandemic and opioid crisis and can be safely applied in resource-constrained settings.

BACKGROUND: Since COVID-19 was declared a worldwide pandemic by the World Health Organization (WHO) in March of 2020, foundation-based cleft outreach programs to Low- and Middle-Income Countries (LMICs) were halted considering global public health challenges, scarcity of capacity and resources, and travel restrictions. This led to an increase in the backlog of untreated patients with cleft lip and/or palate, with new challenges to providing comprehensive care in those regions. Resumption of international outreach programs requires an updated course of action to incorporate necessary safety measures in the face of the ongoing pandemic. In this manuscript, the authors outline safety protocols, guidelines, and recommendations implemented in Global Smile Foundation's (GSF) most recent outreach trip to Beirut, Lebanon. METHODS: COVID-19 safety protocols for outreach cleft care and an Action Response Plan were developed by the GSF team based on the published literature and recommendations from leading international organizations. RESULTS: GSF conducted a 1-week surgical outreach program in Beirut, Lebanon, performing 13 primary cleft lip repairs, 7 cleft palate repairs, and 1 alveolar bone grafting procedure. Safety protocols were implemented at all stages of the outreach program, including patient preselection and education, hospital admission and screening, intraoperative care, and postoperative monitoring and follow-up. CONCLUSIONS: Organizing outreach programs in the setting of infectious diseases outbreaks should prioritize the safety and welfare of patients and team members within the program's local community. The COVID-19 protocols and guidelines described may represent a reproducible framework for planning future similar outreach initiatives in high-risk conditions.

The present study is aimed to assess the adsorptive potential of carbonaceous material for the acyclovir (ACVR) removal from the aquatic environment using batch and fixed-bed processes. In batch mode, the impact of various process conditions (contact time, pH, adsorbent dose, initial ACVR concentration, and temperature) on ACVR adsorption was investigated. Experimental results revealed that Langmuir isotherm and the pseudo-second-order kinetic model adequately represent the ACVR adsorption mechanism, indicating homogeneous adsorption. The process was found exothermic and spontaneous. Thermodynamic studies concluded that adsorption is a result of both physisorption and chemisorption. To understand the dynamic regime for the design of large-scale column studies, experimental data obtained from breakthrough curve were fitted to various analytical kinetic models. Yan model followed by Thomas model demonstrated a greater correlation of breakthrough data, confirming that the results are significant and are in line with Langmuir isotherm and pseudo-second-order kinetic. G-AC exhibits sufficient adsorption capacity for ACVR. Hence, it is concluded that it can be used in a fixed-bed column in continuous mode for the treatment of ACVR-contaminated wastewater. Supplementary Information: The online version contains supplementary material available at 10.1007/s11696-023-02810-7.
RESUMO
Non-governmental organizations (NGOs) aim to alleviate unmet global disease burden and promote collaboration between visiting and host countries. Well-executed emergency response protocols are foundational to providing safe and quality care in an unpredictable global setting. Global Smile Foundation (GSF) instituted a protocol in 2012 based on over three decades of cleft care experience. Here, we update this protocol and provide information on how to address special circumstances such as humanitarian crises and disease outbreaks. The GSF response protocol was developed in conjunction with surgeons, anesthesiologists, nurses, and administrators to ensure all team members are adequately prepared to respond to emergency situations in global outreach. This protocol provides information on pre-departure preparation, onsite setup, operative precautions, and post-departure debriefings. Emphasis is placed on a standardized, reproducible workflow that accounts for necessary site-specific adjustments. Strategies include emergency simulations, site-specific safety checklists, standardized operating room protocols, and well-defined individual responsibilities. The authors also provide anticipatory guidance in addressing unexpected circumstances, such as disease outbreak and natural disaster, during global outreach. In conclusion, a proactive and systematic approach to emergency response and prevention is vital to minimizing morbidity and mortality during surgical outreach initiatives. The GSF protocol represents a reproducible approach that other organizations can adopt and adapt to their unique needs.

BACKGROUND: The fundamental tenets of facial aesthetic surgery education have not changed in centuries. Research is beginning to demonstrate that the Neoclassical Canons and the Golden Ratio, Phi, have limited utilization in populations other than those of White European extraction. OBJECTIVES: The purpose of this study was to analyze comparable raw data in the literature to determine (1) if there is interethnic variability in Neoclassical Canon and Phi measurements, and (2) if the measurements in these representative samples differ from the "ideal." METHODS: A PubMed/Scopus search was performed. Manuscripts with raw data and individuals aged ≥16 were included. Measurements were extracted and employed to calculate the Neoclassical Canons and Phi. One-way analysis of variance (ANOVA) tests were conducted to compare mean measurements across 6 ethnic groups (P < 0.05). RESULTS: Twenty-seven articles were included. Every continent was represented except Antarctica and Australia. Men were less commonly studied than women. Participant ages ranged from 16 to 56. Averaged Canons 2, 6-8 measurements had significant interethnic differences in males, whereas Canons 5-8 had significant differences across ethnicities in females. For men, there was significant interethnic variability in measurements of Phi 2, 5, 8, 10, and 17. For women, Phi 1, 2, 5, 8, 10, and 17 varied across ethnicities. No ethnic/gender group showed consistent approximation of the "ideal" for both the Neoclassical Canons and Phi. CONCLUSIONS: Today, the utility of the Neoclassical Canons and Phi is limited. It is incumbent on our field to systematically study and define the anthropometric measures that define the "ideal."

BACKGROUND: Migraine headache is a common, debilitating condition responsible for astronomical societal burden. The chronicity of migraine headaches necessitates the use of many healthcare services. Preventative treatment remains the desirable option for this patient population. Pharmacologic advances have led to the development of erenumab, a monoclonal antibody calcitonin gene-related peptide receptor antagonist that directly interferes with the known biochemical pathway of migraine initiation. Alternatively, surgical decompression of migraine trigger sites is a historically effective preventative option for certain patients experiencing migraine headaches. As new treatments emerge, the large economic burden of migraine headaches requires cost evaluation against already available preventative modalities. METHODS: Studies evaluating the cost-effectiveness of both erenumab and surgical trigger site deactivation were found using EMBASE and MedLine. Relevant economic data was extracted from this literature and the cost of treatment with erenumab was compared with surgical decompression. RESULTS: The market price of erenumab is $6900/yr. Speculative models predicted a direct annual healthcare cost ranging from $11,404 to $12,988 for patients experiencing episodic migraine. For chronic migraine patients, this range extended to $25,604. Annual indirect costs ranged from $7601 to $19,377. Prospective and model-based studies evaluating surgical trigger site deactivation reported an average 1 time surgical cost between $6956 and $10,303. In episodic migraine, subsequent annual healthcare costs were $900. CONCLUSIONS: Erenumab has potential to be a revolutionary noninvasive preventative treatment for migraine headache. With that said, the cost-conscious option for patients receiving more than 1 year of treatment remains surgical trigger site deactivation.

ABSTRACT: Fibrous dysplasia is a benign overgrowth of metaplastic fibrous material resulting in disorganized deposition of bony matrix. Surgical intervention is the primary treatment modality. Here the authors present the case of a 36-year-old male with extensive and severe fibrous dysplasia of the calvarium, orbit, sphenoid, and facial bones causing significant facial distortion and impingement of his optic nerve. Combined operative treatment with craniofacial plastic surgery and neurosurgery was performed. Repair consisted of extensive intra- and extracranial resection and contouring of involved bones followed by reconstruction of the superior orbital rims, forehead, orbital roof, and calvarium with custom polyetheretherketone (PEEK) implant. The authors discuss the advantages of using computer assisted design/modeling, intraoperative neuronavigation, and custom prosthetic cranioplasty for surgical treatment of extensive fibrous dysplasia; a review of the current surgical literature is provided.

BACKGROUND: At the declaration of the global pandemic on March 11, 2020, many hospitals and institutions developed a tiered framework for the stratification and prioritization of elective surgery. Cleft lip and palate repair was classified as low acuity, and nasoalveolar molding (NAM) clinics were closed. Anticipating the consequences of delayed cleft care and the additional burden this would cause families, we reassessed our risk-stratification and perioperative algorithms. We hypothesized we could safely optimize nasolabial repair without burdening our care systems and without increasing COVID-19-related morbidity/mortality. METHODS: Our multidisciplinary cleft team reevaluated patient selection to maximize surgical impact. Perioperative protocols were adjusted, and COVID-19 preoperative testing was utilized before nasolabial repair and prior to suture removal under anesthesia. RESULTS: Early in the pandemic, unilateral cleft repair was prioritized and successfully completed on 9 patients. There were no complications related to COVID-19. Nasoalveolar molding clinic was reopened after total patient volume was significantly decreased. CONCLUSIONS: We offer an approach for surgical management of nasolabial clefts during a global pandemic. Although guidelines have suggested postponing all cleft care, we found that at our dedicated pediatric hospital with low burden of COVID-19 and adequate resources, we could follow a strategy to safely resume cleft care while decreasing burden on our patients' families and care delivery systems.

INTRODUCTION: Clefts of the lip and palate are leading congenital facial anomalies. Underserved patients with these facial differences lack access to medical care, surgical expertise, prenatal care, or psychological support. Moreover, the disease results in significant economic strains on patients and their families. While surgical outreach programs have attempted to fill this void, significant challenges facing international comprehensive cleft care persist. OBJECTIVE: Propose a path toward international sustainable cleft care based on the Global Smile Foundation experience. RESULTS: International sustainable comprehensive cleft care can be achieved by regulating surgical outreach programs. Regulation of these missions would ensure standardized care and encourage stakeholders to cooperate and adequately allocate funding and resources. Capacity building can be achieved through "diagonal" cleft care delivery models, multidisciplinary workshops, fellowship programs, research and quality assurance, as well as leveraging emerging technologies such as Augmented Reality. CONCLUSION: International comprehensive cleft care requires continuous collaborative efforts between visiting and local teams as well as international and national organizations. Standardizing and regulating current practices as well as promoting capacity building initiatives can contribute to sustainable cleft care.

PURPOSE: Today, medical education emphasizes clinical applications of anatomic knowledge. In 2014, we instituted Clinically Applied Anatomy (CAA) within first-year Human Gross Anatomy at our university. The course was designed and overseen by academic plastic surgery. We hypothesized CAA would positively impact students' understanding, performance, and interest in human anatomy. METHODS: From 2014 to 2018, 13 CAA case-based didactics were integrated into the anatomy curriculum without changing the total anatomy-related student hours; each emphasized the clinical relevance of overlooked (or memorized) anatomic detail. Clinically Applied Anatomy instructors led associated clinical cadaver dissections. Upon course completion, students from each participating class were anonymously surveyed. RESULTS: One hundred sixty-four students completed the survey (75% response). Eighty-six percent reported CAA increased mastery of human anatomy, 77% stated CAA improved examination performance, 87% agreed CAA increased interest in anatomy itself, and 96% reported CAA increased their critical thinking of how understanding anatomy affects clinical care. Nearly half (49.4%) responded that CAA increased interest in applying for a procedurally oriented residency. When considering future integration of CAA into the medical school curriculum, 9% of students wanted less CAA, 61% wanted the same, and 30% wanted more. CONCLUSIONS: Clinically Applied Anatomy significantly impacts medical students' anatomy education. Currently, 17 CAA faculty from 7 departments/divisions participate in all 26 of our school's anatomy sessions. As per our institution, we advocate this cost-effective and impactful initiative be led by academic plastic surgeons. These clinicians possess broad and specialized anatomic expertise as well as the leadership and interdisciplinary working relationships needed to enroll a multidisciplinary team of clinical educators.

In 2016, water lines at a children's dental clinic in Orange County, California were contaminated with Mycobacterium abscessus (MA), a non-tuberculosis rapidly-growing mycobacterium, leading to the largest MA outbreak ever reported. Mandatory reporting and active case finding directed by the Public Health Department was conducted in collaboration with community Pediatric Infectious Disease physicians for patients who underwent dental pulpotomies at the contaminated Dental Clinic from January 1 to September 6, 2016. Seventy-one cases (22 confirmed and 49 probable) were identified. One case that required extensive debridement and reconstruction of the mandible is presented in detail. CT maxillofacial demonstrated osteomyelitis extending from the right mandibular angle to the left ramus with multifocal periapical lucencies. CT chest and neck revealed numerous pulmonary nodules and bilateral cervical lymphadenopathy. Extraction of several involved teeth, bilateral selective neck dissection, and extensive mandibular debridement was performed, followed by mandibular stabilization with a custom pre-bent 2.0-mm locking plate. CT images 1-year post-operative showed clearance of infection and sufficient bony stability. Subsequent removal of hardware and bone grafting was performed and the patient is doing well. In the event of a future odontogenic mycobacterium outbreak, the experience at our institution can inform multidisciplinary treatment approaches. Prophylactic extraction of primary teeth that received pulpotomies with contaminated water should be performed. Early and thorough debridement of affected bone, including enucleation of secondary teeth, should be performed if necessary for early source control.

Dog bites have been well described and characterized in the pediatric population. Comparatively, dog-bite injuries in adults and the settings in which surgeons become involved are less studied. An electronic hospital database identified all patients 18 years or older who were treated for dog bites from 2010 to 2014. Demographics, injury information, intervention type, and payer source were collected. Socioeconomic analysis was performed using Geographic Information Systems mapping. A total of 189 adults presented to the emergency department with dog-bite-related injuries. The most common injury location was the hand (n = 62, 32.8%), followed by the head and neck (n = 36, 19.1%). Of the 189 patients, 33 adults (17.5%) were forwarded to a surgical subspecialist for repair. A head and neck injury was significantly more likely to be repaired by a surgical specialist (P = 0.011). The most common breed of dog identified was pit bull (n = 29, 47.5%). The majority of pit bull attacks involved the extremities (65.5%) compared to other breeds of dogs. Pit bull victims were noted to have a lower average annual income compared to other breed victims ($64,708 versus $75,004; P = 0.16). Annual income between intervention group and no intervention group was not significantly different (P = 0.26). This study is the 1st to perform a socioeconomic analysis in the adult dog-bite population and encourages the use of a surgical specialist in the setting of a head and neck bite.

Granular activated carbon was doped with iron (Fe-AC) and was used to study the removal of Safranin O (SO) using the Fe-AC/H2O2 system for reactive adsorption and Fe-AC for adsorption. Fe-AC and H2O2 doses were optimized to obtain maximum removal of SO. Maximum removal was found to be 96.1% after 5 h using 1.0 g/L Fe-AC and 5.0 mM hydrogen peroxide doses for 10 mg/L initial SO concentration. Kinetic study suggested the suitability of the pseudo-first-order model for reactive adsorption. The Langmuir isotherm explained well the sorption of SO onto Fe-AC. Parallel-pore-reactive adsorption model was applied and validated. By fitting the experimental data to the model, it is observed that the surface reaction rate coefficient, kr, was found to be five times that of the apparent rate constant, kapp. Parameters such as the external liquid film mass transfer coefficient, macro-pore and micro-pore diffusivities were estimated by regression analysis. Pore diffusion and surface reaction were found to be rate controlling for adsorption and reactive adsorption, respectively. An oxidative degradation of SO took place via hydroxylation and ring cleavage processes.

Mixed reality, a blending of the physical and digital worlds, can enhance the surgical experience, leading to greater precision, efficiency, and improved outcomes. Various studies across different disciplines have reported encouraging results using mixed reality technologies, such as augmented and virtual reality. To provide a better understanding of the applications and limitations of this technology in plastic surgery, we performed a systematic review of the literature in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The initial query of the National Center for Biotechnology Information database yielded 2544 results, and only 46 articles met our inclusion criteria. The majority of studies were in the field of craniofacial surgery, and uses of mixed reality included preoperative planning, intraoperative guides, and education of surgical trainees. A deeper understanding of mixed reality technologies may promote its integration and also help inspire new and creative applications in healthcare.
