RESUMO

OBJECTIVE: To investigate health-related quality of life (HRQL) in children aged 2 to 7 years, who have undergone surgery for craniosynostosis. DESIGN: Cross-sectional survey. SETTING: A tertiary pediatric academic medical center. PARTICIPANTS: Children with craniosynostosis who underwent surgical correction, and who were 2-7 years old at the time of the study. Children from families that did not speak English were excluded. INTERVENTIONS: Caregivers were asked to fill out the Pediatric Quality of Life Inventory (PedsQL) Core Parent Report and the PedsQL Cognitive Functioning Scale. MAIN OUTCOME MEASURES: PedsQL: Psychosocial Health Summary Score, Physical Health Summary Score, Total Core Score, Cognitive Functioning Scale Score. Scores range from 0 to 100, with higher scores reflecting greater QoLSubject factors: comorbidities, syndromic status, type of craniosynostosis, type of surgery. RESULTS: The study included 53 subjects, of whom 13.2% had a syndrome. Core and cognitive scores did not depend on presence of a syndrome or suture involved. Subjects who underwent posterior cranial distraction achieved higher Total Core Scores than subjects who underwent open vault remodeling. Among subjects with sagittal craniosynostosis, there was a tendency for higher scores among children who underwent minimally-invasive surgery compared to those who underwent open vault remodeling. CONCLUSIONS: This study demonstrates similar HRQL among children with and without a syndrome, higher HRQL among children undergoing posterior cranial distraction than those undergoing open vault remodeling, and trends towards higher HRQL in children with sagittal craniosynostosis who underwent minimally-invasive surgery compared to those who underwent open vault remodeling.

RESUMO

BACKGROUND: Medical training is known to impose financial burden on trainees, which has been shown to contribute to burnout, even possibly compromising patient care. Financial literacy allows for management of financial situations affecting professional and personal life. The authors aimed to evaluate the financial status and knowledge among plastic surgery residents. METHODS: A survey regarding finances and financial literacy of plastic surgery residents was sent to all the current accredited U.S. residency programs. The same survey was distributed internally. A descriptive analysis was performed, and multiple Fisher exact tests and a t test evaluated comparisons. RESULTS: Eighty-six residents were included. Most trainees had a student loan (59.3%), with 22.1% having loans more than $300,000. A majority had at least one personal loan debt other than educational (51.1%). Residents with more debt were significantly less likely to pay off their balances monthly. A total of 17.4% of trainees had no plan for how to invest their retirement savings, whereas 55.8% reported not knowing how much they need to save to retire. One in five trainees did not feel prepared to manage personal finances/retirement planning after graduation, a majority had no formal personal finance education in their curriculum, and 89.5% agreed that financial literacy education would be beneficial. Our institutional data largely mirrored national data. CONCLUSIONS: Many residents are lacking in financial knowledge, despite most having significant debt. Additional financial literacy education is needed in plastic surgery training. Curricula development at an institutional or national society level are possible paths toward a coordinated response to this need.

RESUMO

Papillary hemangioma (PH) is a small, primarily dermal lesion occurring predominantly in the head and neck in both children and adults. Its signature characteristics are dilated thin-walled channels containing papillary clusters of mainly capillary-sized vessels and endothelial cytoplasmic eosinophilic inclusions. Given certain histopathologic similarities to congenital hemangioma which harbor mutations in GNAQ and GNA11 , we investigated whether similar mutations are present in PH. Seven PH specimens were studied. All presented in the first 4 years of life, with one being noted at birth. With the exception of one lesion, all were in the head and neck. Lesions were bluish and ranged in size from 0.5 to 2.8 cm. Four samples had GNA11 p.Q209L and 3 had GNAQ p.Q209L missense mutations. Mutations in GNA11 and GNAQ are associated with other types of somatic vascular lesions including capillary malformation, congenital hemangioma, anastomosing hemangioma, thrombotic anastomosing hemangioma, and hepatic small cell neoplasm. Shared mutations in GNA11 and GNAQ may account for some overlapping clinical and pathologic features in these entities, perhaps explicable by the timing of the mutation or influence of the germline phenotype.

RESUMO

OBJECTIVE: Posterior cranial distraction (PCD) is a surgical technique to address craniosynostosis, especially in syndromic patients. The technique has the ability to significantly expand the cranium, while requiring minimal dural dissection, compared to cranial remodeling. Our goals were to determine the patient characteristics and surgical outcomes of PCD. The two questions that we sought to answer were: 1) What is the average published complication rate and the most common complications of PCD? and 2) How much intracranial volume expansion can one expect with PCD? DESIGN: A PubMed database search of articles on PCD was performed. Case reports and articles with overlapping patients were excluded. A systematic review was performed using the remaining articles. MAIN OUTCOME MEASURES: Patient data were extracted in order to determine the total number of patients, patients with a syndrome, types of syndromes, mean age at surgery, mean distraction distance, mean increase in intracranial volume, and complications. RESULTS: 18 articles representing 325 patients were analyzed. A syndrome was present in 68.6% of patients. The mean age at time of surgery was 22.1 months. Mean distraction amount was 24.7 mm. Mean increase in intracranial volume was 253.2 cm3. The overall complication rate was 32.2%, with the most common complications being surgical-site infection, hardware-related complications and delayed wound healing. CONCLUSIONS: PCD is a powerful technique in the management of syndromic craniosynostosis, although complication rates are significantly higher than traditional remodeling techniques. Future studies should compare the effects of supratorcular and infratorcular osteotomies on intracranial volume, cosmesis and complications.

RESUMO

BACKGROUND: Controversy remains regarding optimal management of Pierre Robin sequence (PRS). The goal of this study was to compare airway and feeding outcomes in infants with PRS who underwent surgical intervention, specifically mandibular distraction osteogenesis (MDO) or tongue-lip adhesion (TLA), or who had conservative management (CM) without surgery. METHODS: All consecutive patients treated for PRS at a pediatric academic medical center, with at least one year follow-up, were included. Patients who underwent tracheostomy as an index procedure were excluded. Patients were divided into those who underwent MDO, TLA or CM. Feeding status and data from initial and follow-up polysomnograms were collected. Comparisons between groups were made using the Kruskal-Wallis test, followed by Mann-Whitney pairwise comparison with a Bonferroni correction, when appropriate. RESULTS: 67 neonates were included. 19 underwent TLA, 29 underwent MDO and 19 underwent CM. The proportions of syndromic patients were similar between groups. Patients undergoing CM had the lowest baseline AHI (9.1), but there were no significant differences between TLA (20.1) and MDO (25.4). At follow-up, the three groups had similar mean AHI (MDO 1.3, TLA 4.2, CM 4.5). A similar proportion of patients achieved AHI 5 or less (TLA 89.5%, MDO 96.6%, CM 84.2%). At one year, there were no significant differences in weight percentiles or in risk of failure-to-thrive between groups. One patient from the TLA group required a tracheostomy. CONCLUSION: The three treatment modalities achieved high airway and feeding success rates. All three modalities should have a place in the armamentarium of the craniofacial surgeon.

RESUMO

PURPOSE: RAS genes (HRAS, KRAS, and NRAS) are commonly found to be mutated in cancers, and activating RAS variants are also found in disorders of somatic mosaicism (DoSM). A survey of the mutational spectrum of RAS variants in DoSM has not been performed. METHODS: A total of 938 individuals with suspected DoSM underwent high-sensitivity clinical next-generation sequencing-based testing. We investigated the mutational spectrum and genotype-phenotype associations of mosaic RAS variants. RESULTS: In this article, we present a series of individuals with DoSM with RAS variants. Classic hotspots, including Gly12, Gly13, and Gln61 constituted the majority of RAS variants observed in DoSM. Furthermore, we present 12 individuals with HRAS and KRAS in-frame duplication/insertion (dup/ins) variants in the switch II domain. Among the 18.3% individuals with RAS in-frame dup/ins variants, clinical findings were mainly associated with vascular malformations. Hotspots were associated with a broad phenotypic spectrum, including vascular tumors, vascular malformations, nevoid proliferations, segmental overgrowth, digital anomalies, and combinations of these. The median age at testing was higher and the variant allelic fraction was lower in individuals with in-frame dup/ins variants than those in individuals with mosaic RAS hotspots. CONCLUSION: Our work provides insight into the allelic and clinical heterogeneity of mosaic RAS variants in nonmalignant conditions.

RESUMO

Background. Lower extremity injuries in the pediatric population that are associated with Gustillo 3B/3C fractures require special consideration. Limb salvage should be attempted in the pediatric patient if at all possible, and oftentimes the soft tissue defect that is present over the bony fracture is substantial. The traditional algorithm used in the management of Gustillo 3B/3C fractures in plastic surgery, referred to as the reconstructive ladder, would recommend flap reconstruction with free tissue transfer in most cases because regional options are often unavailable or do not provide adequate coverage. Free tissue transfer procedures are extensive and necessitate a donor site; they often require multiple procedures and subsequent revisions. Furthermore, when concomitant injuries or medical conditions are present, a patient may not be an appropriate candidate for a free flap. Another option, however, does exist for the pediatric patient with a significant lower extremity injury that is often overlooked by the plastic surgeon. Several articles in the orthopedic literature describe the utility of temporary limb deformation to allow for soft tissue closure, with gradual correction of the bony deformity over time. Although the healing process for these procedures take several months, there is no need for extensive soft tissue reconstruction and the ultimate result is a leg that is functional with adequate coverage. This article reports a case where this type of bone and soft tissue reconstruction was performed in a patient with an excellent overall outcome. This technique could be useful in select cases as an option in pediatric lower extremity reconstruction.

RESUMO

INTRODUCTION: Hidradenitis suppurativa can be a debilitating condition, particularly in the pediatric population. Axillary hidradenitis can be particularly challenging because of the risk of scar contracture and limited range of motion after definitive resection and reconstruction. A dermal regeneration template (DRT) and skin grafting have been used to reduce scar contracture in other areas of the body and may benefit this population. OBJECTIVE: This case series retrospectively reviewed and evaluated outcomes using DRT and skin grafting for axillary hidradenitis reconstruction to report the authors' initial experience. MATERIALS AND METHODS: After institutional review board approval, a retrospective review was conducted of a single surgeon's experience for all patients undergoing axillary hidradenitis resection and immediate reconstruction with DRT and skin grafting from 2015 through 2018. Preoperative characteristics, surgical details, and postoperative results were collected. RESULTS: Five patients undergoing 7 procedures were eligible for inclusion. The average age at the time of surgery was 18.2 years. Patients underwent an average of 4.9 negative pressure wound therapy changes prior to skin grafting. No complications, DRT loss, or skin graft loss occurred. All patients were reported to have normal range of motion of the surgically managed extremity after skin grafting. The average follow-up was 273.4 days after the last procedure. As of this writing, no patients had experienced any recurrence of hidradenitis in the surgically managed axilla. CONCLUSIONS: The use of DRT and subsequent skin grafting for the definitive management of axillary hidradenitis resulted in no recurrence and full range of motion of the affected extremity without complications. Surgeons should consider using this method of reconstruction for axillary hidradenitis, particularly in the pediatric population.

RESUMO

The second victim phenomenon is the distress felt by healthcare providers after a medical error. Although the phenomenon is a significant risk factor for burnout, little has been written about it in surgery, especially among residents. Methods: After institutional review board approval, a 27-question anonymous online survey was sent to plastic surgery residents throughout the United States, and to residents from all surgical specialties at our institution, for a total of 435 residents. Residents were asked to describe any adverse events they had experienced, and subsequent emotional sequelae. Results: The survey was returned by 125 residents (response rate 28.7%), of whom 53 were plastic surgery residents (42.4%) and 72 were from other surgical specialties (57.6%). In total, 110 (88%) described having been part of a medical error. An estimated 74 residents (34 from plastic surgery, 40 from other surgical specialties) provided a detailed description of the event. Sixty-four of them (86.5%) had subsequent emotional sequelae, most commonly guilt, anxiety, and insomnia. Only 24.3% of residents received emotional support. They rated other residents as the most important source of support, followed by faculty members and then family/friends. Conclusions: The second victim phenomenon seems to be common among surgical residents. The most important source of support for affected residents in our cohort was other residents. Given these findings, institutions should focus on fostering camaraderie among residents, building effective second victim response teams and training peer support specialists.

RESUMO

Closed spinal dysraphism (SD) is a type of neural tube defect originating during early embryonic development whereby the neural tissue of the spinal defect remains covered by skin, often coinciding with markers of cutaneous stigmata. It is hypothesized that these events are caused by multifactorial processes, including genetic and environmental causes. We present an infant with a unique congenital midline lesion associated with a closed SD. Through comprehensive molecular profiling of the intraspinal lesion and contiguous skin lesion, an internal tandem duplication (ITD) of the kinase domain of the fibroblast growth factor receptor 1 (FGFR1) gene was found. This ITD variant is somatic mosaic in nature as supported by a diminished variant allele frequency in the lesional tissue and by its absence in peripheral blood. FGFR1 ITD results in constitutive activation of the receptor tyrosine kinase to promote cell growth, differentiation, and survival through RAS/MAPK signaling. Identification of FGFR1 ITD outside of central nervous system tumors is exceedingly rare, and this report broadens the phenotypic spectrum of somatic mosaic FGFR1-related disease.

RESUMO

Syringocystadenocarcinoma papilliferum (SCACP) is a rare malignant neoplasm arising from adnexal tissues and is the malignant complement to the benign neoplasm syringocystadenoma papilliferum (SCAP). SCACP lesions appear as raised nodules or inflammatory plaques and can be associated with SCAP or nevus sebaceous. There have been fewer than 100 described cases of this neoplasm in the literature, and all previously published cases have been described in adults, with the majority occurring in the elderly. We present a case of an adolescent female with a syringocystadenocarcinoma papilliferum arising from a large thigh mass harboring an in-frame alteration in MAP2K1 along with a brief review of the literature.

RESUMO

To improve psychosocial risk assessment and service provision for children with craniofacial conditions presenting for annual interdisciplinary team visits.Institute for Healthcare quality improvement model.U.S. pediatric academic medical center.Caregivers of children ages 0-17 years with craniofacial conditions presenting for 1692 team visits between August 2017 and July 2019.Key drivers included: (1) standardizing pre-visit triage processes; (2) administering the Psychosocial Assessment Tool-Craniofacial Version (PAT-CV); (3) utilizing PAT-CV scores in real time to add patients to psychosocial provider schedules; and (4) family education. Interventions included improving patient screening, increasing PAT-CV completion rate, altering clinic flow, providing patient and parent education about psychosocial services, and altering team member roles to fully integrate PAT-CV administration and scoring in the clinic.The primary outcome was the percentage of patients identified for psychosocial consultations via nurse triage, PAT-CV score, family or provider request who completed consultations. The secondary outcome was the percentage of patients completing needed psychosocial consultations based on elevated PAT-CV scores.Use of the PAT-CV resulted in an increase in the percentage of patients with elevated psychosocial risk who received a psychosocial consultation from 86.7% to 93.4%. The percentage of children receiving psychosocial consultation at their annual team visit due to elevated PAT-CV scores increased from 72% to 90%.Integrating a validated psychosocial risk screening instrument can improve risk identification and psychosocial consultation completion. A combination of risk screening approaches may be indicated to identify patients in need of psychosocial services.

RESUMO

Cerebral cavernous malformations (CCM) may present in sporadic or familial forms, with different cutaneous manifestations including deep blue nodules, capillary malformations, and hyperkeratotic cutaneous capillary venous malformations (HCCVM). We report the case of an infant with a KRIT1-positive HCCVM associated with familial CCM. Moreover, histopathology showed positive immunohistochemical stain with GLUT1, further expanding the differential diagnosis of GLUT1-positive vascular anomalies.

RESUMO

INTRODUCTION: We sought to compare outcomes and parental satisfaction between 2 approaches for sagittal craniosynostosis: strip craniectomy with spring-mediated skull remodeling (SMSR) and strip craniectomy with postoperative helmet (SCH). METHODS: Perioperative and outcome data for SMSR or SCH patients between September 2010 and July 2019 were retrospectively reviewed. A telephone survey was administered to parents of children who underwent both procedures. RESULTS: A total of 62 children were treated for sagittal craniosynostosis by either SMSR (n = 45) or SCH (n = 17). The SCH group had a lower estimated blood loss (27 vs. 47.06 mL, p = 0.021) and age at surgery (13.0 vs. 19.8 weeks) than the SMSR group. Three patients underwent early springs removal due to trauma or dislodgement, all of whom converted to helmeting. Of the 62 children initially identified, 59 were determined to have an adequate follow-up time to assess long-term outcomes. The mean follow-up time was 30.1 months (n = 16) in the SCH group and 32.0 months in the SMSR group (n = 43, p = 0.39). Two patients in the SCH group and one in the SMSR group converted to open cranial vault reconstruction. Thirty parents agreed to respond to the satisfaction survey (8 SCH, 22 SMSR) based on a Likert scale of responses (0 being most dissatisfied possible, 4 most satisfied possible). Average satisfaction was 3.86/4.0 in the SCH group and 3.45/4.0 in the SMSR group. No parents in the SCH group would change to SMSR, while 3 of the 22 SMSR survey responders would have changed to SCH. CONCLUSIONS: Perioperative outcomes and average parental satisfaction were similar in both groups. Importance of helmet wear compliance and risk of spring dislodgement should be discussed with parents.

RESUMO

BACKGROUND: Despite regulations currently in place, the incidence of lawnmower injuries in children has not decreased for several decades in the United States. In fact, studies in several countries show that the incidence of riding lawnmower injuries are actually on the rise worldwide. Those injuries tend to be devastating and limb-threatening. The purpose of this study was to evaluate a pediatric trauma center's experience with those injuries over the past 25 years. METHODS: All patients who presented to a level I pediatric trauma center with injuries from lawnmowers between 1994 and 2019 were reviewed. Date of birth, gender, date of injury, mechanism of injury, type of lawnmower, and type of injury (including whether an open fracture, soft tissue defect, and/or amputation were present) were recorded. RESULTS: A total of 142 pediatric patients were treated over the study period. The average age was 7.5 years. The three most common mechanisms of injury were being hit by a riding lawnmower moving forward, falling off a riding lawnmower, and being hit by a riding lawnmower moving backward. Of all patients, 68.3% sustained an open fracture and 38% required an amputation. Riding lawnmowers resulted in more operative procedures, longer hospital stays, and more soft tissue defects that require reconstruction than push mowers. Younger patients were at a higher risk to sustain proximal amputations (wrist/ankle or proximal) than older patients. CONCLUSION: Lawnmower injuries are devastating and largely avoidable. There are currently recommendations and regulations in the United States, which if followed, would prevent the vast majority of pediatric lawnmower injuries. Unfortunately, the incidence of these injuries has not decreased despite the current regulations. Broader public education is essential to decrease the incidence of serious lawnmower injuries in children.Level of Evidence: IV.

RESUMO

The antigenic diversity of Orientia tsutsugamushi as well as the interstrain difference(s) associated with virulence in mice impose the necessity to dissect the host immune response. In this study we compared the host response in lethal and non-lethal murine models of O. tsutsugamushi infection using the two strains, Karp (New Guinea) and Woods (Australia). The models included the lethal model: Karp intraperitoneal (IP) challenge; and the nonlethal models: Karp intradermal (ID), Woods IP, and Woods ID challenges. We monitored bacterial trafficking to the liver, lung, spleen, kidney, heart, and blood, and seroconversion during the 21-day challenge. Bacterial trafficking to all organs was observed in both the lethal and nonlethal models of infection, with significant increases in average bacterial loads observed in the livers and hearts of the lethal model. Multicolor flow cytometry was utilized to analyze the CD4+ and CD8+ T cell populations and their intracellular production of the cytokines IFNγ, TNF, and IL2 (single, double, and triple combinations) associated with both the lethal and nonlethal murine models of infection. The lethal model was defined by a cytokine signature of double- (IFNγ-IL2) and triple-producing (IL2-TNF-IFNγ) CD4+ T-cell populations; no multifunctional signature was identified in the CD8+ T-cell populations associated with the lethal model. In the nonlethal model, the cytokine signature was predominated by CD4+ and CD8+ T-cell populations associated with single (IL2) and/or double (IL2-TNF) populations of producers. The cytokine signatures associated with our lethal model will become depletion targets in future experiments; those signatures associated with our nonlethal model are hypothesized to be related to the protective nature of the nonlethal challenges.

RESUMO

BACKGROUND: Minimal invasive suturectomy is one of the many surgical approaches to treat isolated single suture craniosynostosis. This approach can be technically challenging in metopic craniosynostosis given the narrow corridor and steep angle of the forehead. New instruments such as the Piezosurgery device (Mectron) have the potential to improve the ability to safely perform minimal invasive surgery in metopic craniosynostosis. OBJECTIVE: To demonstrate the safety and efficacy of Piezosurgery technology in minimal invasive suturectomy for nonsyndromic metopic suture craniosynostosis and to describe our technique. METHODS: A retrospective chart review was performed of all the single metopic suturectomies performed at our single institution from March 2018 to November 2019. Pre-, intra-, and postoperative data were collected to assess the safety of Piezosurgery. RESULTS: The cohort consisted of 12 patients with an average of 95.25 d old and an average weight of 6.2 kg. A total of 91.7% were male, and 91.7% were Caucasian. There were no intraoperative or postoperative Piezosurgery device-related complications in the entire cohort. CONCLUSION: The use of the Piezosurgery instrument was safe in this cohort of minimal invasive metopic suturectomy. This device has greatly increased the ease of this procedure in our hands.

RESUMO

BACKGROUND: The most common surgical intervention to treat velopharyngeal dysfunction in the US is the posterior pharyngeal flap (PPF). In this retrospective study, the authors compare surgical and speech outcomes across 2 PPF surgical approaches: the palatal split (PS) and fish mouth (FM) techniques. METHODS: An Institutional Review Board approved retrospective chart review was performed for PPF cases performed by a single surgeon between 2008 and 2016. Overall, 40 patients received the PS technique and 47 received the FM technique. Age at surgery, operative length, length of stay (LOS), revisional surgery, and pain medication administration were measured. Speech outcomes were measured based on the Universal Parameters for Reporting Speech Outcomes and included Speech Language Pathologist ratings of hypo- and hypernasality, speech acceptability, and audible nasal emission. Two sample t-tests and multivariable-mixed effects logistic regression were used to analyze the data. RESULTS: Comparing the 2 groups (PS versus FM), there were statistically significant differences among the operative approaches across multiple measures: LOS (32.86 hours versus 26.20 hours, P = 0.01), acetaminophen use (1523.54 mg versus 805.74 mg, P = 0.01), revisional surgery rate (17.5% versus 2.10%, P = 0.02), and degree of postoperative hypernasality (0.61 versus 0.29, P = 0.03). Syndromic patients were more likely to receive the FM technique (PS: 15% versus FM: 29.8%; P = 0.05). The odds ratio for revision surgery with the FM technique was -2.32 (CI: -4.32 to -0.35, P = .04). CONCLUSIONS: In this study, the FM technique offered a shorter LOS, lower revision rate, less acetaminophen administration, and more favorable speech outcomes when compared to the PS technique.

RESUMO

OBJECTIVE: The aim of this paper is to discuss ways to incorporate spring-assisted cranioplasty into the surgical armamentarium for craniosynostosis. BACKGROUND: Spring-assisted cranioplasty after cranial suturectomy for craniosynostosis was popularized in the literature by Dr Lauritzen in 2008 after reporting the results of the first 100 cases. Since that time, more craniofacial surgeons and neurological surgeons have incorporated this surgical technique for treatment of patients presenting with craniosynostosis. This paper will discuss how the team at Nationwide Children's Hospital has incorporated spring-assisted cranioplasty into the care of patients presenting with sagittal synostosis. METHODS: In this article, the authors review our previous protocol for the treatment of children with sagittal synostosis prior to the introduction of spring cranioplasty. The authors then describe the impetus for incorporating spring-assisted cranioplasty for sagittal synostosis into our practice, and barriers we encountered during this implementation. The authors then discuss their current, comprehensive protocol for treating children with sagittal craniosynostosis. Finally, the authors review the expected and unexpected advantages that our craniofacial program has experienced as they implemented spring-assisted cranioplasty. CONCLUSION: Incorporation of spring-assisted cranioplasty for sagittal synostosis offers an additional minimally invasive technique, which presents great advantages for many families, and is rewarding for both craniofacial and neurological surgeons.
