RESUMO

Children are disproportionately affected by burn injuries. Differences between adult and pediatric burns range from epidemiologic characteristics to pathophysiological considerations, which vary between different age subgroups. All these factors must be considered in each phase of burn care. This article reviews the most important aspects of the management of a pediatric burned patient starting from the acute through reconstructive phases.

RESUMO

A 66-year-old immunocompromised man presented with cellulitis around the left eye that was initially concerning for necrotizing fasciitis. Exam findings were remarkable for exquisite periocular tenderness with rigid, immobile eyelids resulting from severe erythema, edema, and induration. Given the concern for orbital compartment syndrome and a necrotizing infection, the patient was taken urgently to the operating room for debridement of the eyelid skin as well as an urgent lateral canthotomy and cantholysis. His eye exam revealed 360° of hemorrhagic chemosis, no relative afferent pupillary defect, and an ipsilateral elevated intraocular pressure of 35 mm Hg. No visual acuity measurement could be obtained secondary to the patient's altered mental status. His intraocular pressure normalized after treatment with antihypertensive drops and further extension of the canthotomy. Histopathological analysis showed extensive neutrophilic infiltrate of the dermis which was compatible with a diagnosis of Sweet's syndrome.

RESUMO

The novel coronavirus, SARS-CO V2 responsible for COVID-19 pandemic is rapidly escalating across the globe. Burn centers gearing for the pandemic must strike a balance between contributing to the pandemic response and preserving ongoing burn care in a safe and ethical fashion. The authors of the present communication represent seven burn centers from China, Singapore, Japan, Italy, Spain, the United Kingdom (UK), and the United States (US). Each center is located at a different point along the pandemic curve and serves different patient populations within their healthcare systems. We review our experience with the virus to date, our strategic approach to burn center function under these circumstances, and lessons learned. The purpose of this communication is to share experiences that will assist with continued preparations to help burn centers advocate for optimum burn care and overcome challenges as this pandemic continues.

RESUMO

AIM: The functional and structural complexities accompanying syndromic craniosynostosis make dental care for these patients particularly challenging. We report a case of long-term care for a syndromic craniosynostosis patient. The objective of this report is to introduce special care guidance and clinical recommendation, so that oral health care providers, as key members of a multidisciplinary care team, can provide optimal diagnosis, treatment, and management for the patient with syndromic craniosynostosis. CASE REPORT: The patient of this case report had a medical history of syndromic craniosynostosis involving multiple comorbidities. Over the past 20 years, a multidisciplinary care team has successfully treated the patient. Dental and medical procedures that the patient has received include cranial surgeries, prophylactic dental care, caries control, growth hormone therapy, comprehensive orthodontic treatment in conjunction with orthognathic surgeries, and plastic surgery. CONCLUSION: Oral health care providers can play essential roles in multidisciplinary care for patients with craniosynostosis by understanding the patients' unique oral health conditions and dentofacial deformities. To provide optimal oral health care in a multidisciplinary team, clear communication between the members of the care team is crucial.

RESUMO

PURPOSE: In syndromic craniosynostosis, the Le Fort III osteotomy is used to correct dental/skeletal imbalance, improve exorbitism, and increase the airway. The purpose of this study is to perform a cost comparison between the standard technique of single-stage rigid internal fixation and distraction osteogenesis (DO) in the Le Fort III osteotomy in this patient population. METHOD: Hospital cost accounting databases were queried for patients undergoing single-stage advancement (SS) or DO from 2007 to 2016. Nominal cost data were adjusted using the Bank of Canada Consumer Price Index. Reported costs represented the full length of stay for all utilization per patient. Demographic information and cost data for single-stage osteotomy and DO were compared. RESULTS: Total costs for single-stage (n = 8) were higher than distraction (n = 6; mean $CAD57 825 vs $38 268, P < .05). Intensive care unit (ICU) costs for single-stage were significantly higher than distraction (mean, $17 746 vs $5585, P < .005). Distraction cases had higher operating room (OR) costs than single stage, but the difference was not significant (mean, $12 540 vs $9696). Length of stay was significantly longer for SS patients (mean, 11 days vs 7 days, P < .05). CONCLUSIONS: This single-institution retrospective cost analysis indicates standard SS rigid internal fixation Le Fort III is more costly than DO. Despite higher OR costs, prolonged ICU and hospital stay was the primary reason behind this difference. This information may be of benefit when advocating for new technology perceived as high cost.


OBJECTIFS: En cas de craniosynostose syndromique, l'ostéotomie de Le Fort III permet de corriger un déséquilibre dentaire et squelettique, d'améliorer l'exophtalmie et de mieux ouvrir les voies respiratoires. La présente étude vise à comparer les coûts de la technique standard de fixation interne rigide en une étape à la distraction osseuse (DO) au sein de la population de patients en cas d'ostéotomie de Le Fort III. MÉTHODOLOGIE: Les chercheurs ont fouillé les bases de données comptables des coûts hospitaliers pour les patients qui avaient subi un avancement en une étape (AUÉ) ou une DO entre 2007 et 2016. Ils ont rajusté les données sur les coûts nominaux à l'aide de l'indice des prix à la consommation de la Banque du Canada. Les coûts déclarés représentaient la durée totale de tous les séjours hospitaliers par patient. Ils ont comparé l'information démographique et les données sur les coûts de l'ostéotomie en une étape à la DO. RÉSULTATS: Les coûts totaux de l'AUÉ (n = 8) étaient plus élevés que ceux de la DO (n = 6) (moyenne de 57 825 $ CA par rapport à 38 268 $, P < 0,05). Les coûts de l'unité de soins intensifs (USI) pour les AUÉ étaient considérablement plus élevés que la ceux de la DO (moyenne de 17 746 $ par rapport à 5 585 $, P < 0,005). Les cas de DO s'associent à un rapport de cotes des coûts plus élevé que l'AUÉ, mais la différence n'était pas significative (moyenne de 12 540 $ par rapport à 9 696 $). Le séjour hospitalier était considérablement plus long pour les patients subissant un AUÉ (moyenne de 11 jours par rapport à sept jours, P < 0,05). CONCLUSIONS: D'après la présente analyse rétrospective des coûts dans un seul établissement, la fixation interne rigide de l'AUÉ standard de Le Fort III est plus coûteuse que la DO. Malgré des coûts plus élevés en salle opératoire, un séjour prolongé à l'USI et à l'hôpital est la principale raison de cette différence. Cette information peut être utile pour défendre les nouvelles technologies qui sont perçues comme coûteuses.

RESUMO

Background In New Zealand, pre-exposure prophylaxis (PrEP) should target gay and bisexual men (GBM), and equity is an important principle. Baseline characteristics of GBM offered PrEP in a demonstration project with an enrolment quota of 50% non-Europeans are described. METHODS: An open-label, single-arm treatment evaluation study design ('NZPrEP') was used. The settings were four publicly funded sexual health clinics in Auckland in 2017. The study population was 150 GBM recruited from clinics, community sources and social media. Participants self-completed an online questionnaire about PrEP awareness, attitudes and sexual risk behaviour in the last 3 months. Baseline characteristics are described and examined to determine whether these were associated with PrEP initiation status (self-referral vs doctor/nurse recommendation). RESULTS: In total, 150 GBM of whom half (52%) were non-European, including 21.3% Maori, 19.3% Asian and 8.7% Pacific, were enrolled into the study. Two-thirds (65.3%) self-referred for PrEP and one-third (34.7%) were recommended PrEP by the doctor/nurse. Participants reported a high number of male condomless receptive anal intercourse partners (MenAICLR) (median 3, range 0-50), with 10% reporting 10 or more MenAICLR and 45.3% reporting group sex. In the previous year, 65.3% had a sexually transmissible infection (STI); 18% had rectal chlamydia or gonorrhoea at enrolment. Almost half (47.7%) had recently used drugs with sex, including 8.1% who used methamphetamine. Participants recommended PrEP had lower education, lived less centrally and had a higher STI prevalence than PrEP self-referrers, but their risk behaviour was similar. CONCLUSIONS: Early PrEP adopters in New Zealand have high HIV risk. Demonstration projects should consider equity mechanisms so that minorities can participate meaningfully.

RESUMO

The cleft nasal deformity remains the most likely stigma of the cleft to remain plainly visible despite vigorous and repeated attempts at correction. This deformity is present at birth, but evolves over time. Certain aspects can be treated early, but some, such as the dorsal and septal deformity continue to develop as facial growth proceeds through adolescence. This article presents a conceptual mechanism and a philosophy of conservative reliable gains starting at the primary operation, with the long-term view of achieving definitive correction at maturity. Cogent planning of longitudinal care of the deformity from infancy leads to solid, predictable results.

RESUMO

BACKGROUND: The transfer of patients with hand injuries involves a commitment of substantial resources, emphasizing the importance of understanding factors that may influence referral patterns. Anecdotal experience suggests that the likelihood of transfer increases during nights and weekends. This study aimed to analyze patterns of hand trauma transfers to Duke University Medical Center with respect to timing and patient insurance status. METHODS: The authors performed a retrospective chart review and analysis of 1147 consecutive patient transfers from 2005 to 2010 at a single level 1 university trauma center. Data categories included timing of transfer, patient demographics, insurance status, diagnosis, and procedures performed. Statistical analysis was performed using SAS software (SAS Institute Inc., Cary, N.C.). RESULTS: Of the patient sample, 39.8 percent was female, 30 percent were African American, and 57.3 percent were white. Contrary to our expectations, transfers were more likely during the day (p = 0.0001). Likewise, patients were more likely to present on weekdays than on weekends (p = .001). Although uninsured patients were not disproportionately represented overall, they were more frequently transferred at night (p = 0.0001), despite having the same complexity of injuries as privately insured patients. Conversely, patients with private insurance were less likely to be transferred at night (p = 0.0001). CONCLUSIONS: Similar to studies in other surgical specialties, this analysis demonstrates significant associations between insurance status and hand injury transfer patterns. The current climate, including declining numbers of surgeons willing to provide emergency hand care, diminishing reimbursements, and an expanding uninsured patient population, threatens to exacerbate these concerning trends in trauma patient management.

RESUMO

BACKGROUND: Transplant arteriosclerosis (TA) is the pathognomonic feature of chronic rejection, the primary cause of allograft failure. We have shown that the NF-κB inhibitory protein A20 exerts vasculoprotective effects in endothelial and smooth muscle cells (SMC), and hence is a candidate to prevent TA. We sought direct proof for this hypothesis. METHODS: Fully mismatched, C57BL/6 (H2) into BALB/c (H2), aorta to carotid allografts were preperfused with saline, recombinant A20 adenovirus (rAd.A20) or rAd.ß-galactosidase (ß-gal), implanted, harvested 4 weeks after transplantation, and analyzed by histology, immunohistochemistry, and immunofluorescence staining. We measured indoleamine 2,3-dioxygenase, interleukin-6, and transforming growth factor-ß mRNA and protein levels in nontransduced, and rAd.A20 or rAd.ß-gal-transduced human SMC cultures after cytokine treatment. RESULTS: Vascular overexpression of A20 significantly reduced TA lesions. This correlated with decreased graft inflammation and increased apoptosis of neointimal SMC. Paradoxically, T-cell infiltrates increased in A20-expressing allografts, including the immunoprivileged media, which related to A20 preventing indoleamine 2,3-dioxygenase upregulation in SMC. However, infiltrating T cells were predominantly T-regulatory cells (CD25+/Forkhead Box P3 [FoxP3+]). This agrees with A20 inhibiting interleukin-6 and promoting transforming growth factor-ß production by medial SMC and in SMC cultures exposed to cytokines, which favors differentiation of regulatory over pathogenic T cells. CONCLUSIONS: In summary, A20 prevents immune-mediated remodeling of vascular allografts, therefore reduces TA lesions by affecting apoptotic and inflammatory signals and modifying the local cytokine milieu to promote an immunoregulatory response within the vessel wall. This highlights a novel function for A20 in local immunosurveillance, which added to its vasculoprotective effects, supports its therapeutic promise in TA.

RESUMO

OBJECTIVE: Neointimal hyperplasia is an inflammatory and proliferative process that occurs as a result of injury to the vessel wall. We have shown that the homeostatic protein A20 prevents neointimal hyperplasia by affecting endothelial cell (EC) and smooth muscle cell (SMC) responses to injury. In this work, we questioned whether A20 impacts other pathogenic effectors of neointimal hyperplasia including homing of monocyte/macrophages and EC/SMC precursors to the site of vascular injury, vascular endothelial growth factor (VEGF) secretion, and adventitial neovascularization. METHODS AND RESULTS: Carotid balloon angioplasty was performed on rat recipients of a bone marrow transplant from green fluorescent rats. Adenoviral delivery of A20 prevented neointimal hyperplasia and decreased macrophage infiltration. This was associated with decreased ICAM-1 and MCP-1 expression in vitro. Additionally, A20 reduced neovascularization in the adventitia of balloon injured carotid arteries, which correlated with fewer VEGF positive cells. CONCLUSIONS: A20 downregulates adhesion markers, chemokine production, and adventitial angiogenesis, all of which are required for macrophage trafficking to sites of vascular injury. This, in turn, diminishes the inflammatory milieu to prevent neointimal hyperplasia.

RESUMO

A20 is a NF-kappaB-dependent gene that has dual anti-inflammatory and antiapoptotic functions in endothelial cells (EC). The function of A20 in smooth muscle cells (SMC) is unknown. We demonstrate that A20 is induced in SMC in response to inflammatory stimuli and serves an anti-inflammatory function via blockade of NF-kappaB and NF-kappaB-dependent proteins ICAM-1 and MCP-1. A20 inhibits SMC proliferation via increased expression of cyclin-dependent kinase inhibitors p21waf1 and p27kip1. Surprisingly, A20 sensitizes SMC to cytokine- and Fas-mediated apoptosis through a novel NO-dependent mechanism. In vivo, adenoviral delivery of A20 to medial rat carotid artery SMC after balloon angioplasty prevents neointimal hyperplasia by blocking SMC proliferation and accelerating re-endothelialization, without causing apoptosis. However, expression of A20 in established neointimal lesions leads to their regression through increased apoptosis. This is the first demonstration that A20 exerts two levels of control of vascular remodeling and healing. A20 prevents neointimal hyperplasia through combined anti-inflammatory and antiproliferative functions in medial SMC. If SMC evade this first barrier and neointima is formed, A20 has a therapeutic potential by uniquely sensitizing neointimal SMC to apoptosis. A20-based therapies hold promise for the prevention and treatment of neointimal disease.
