The Radiographic "Air Sign" in Neonatal Mandibular Distraction Osteogenesis.

Timing of extubation on post-mandibular distraction osteogenesis (MDO) surgery is critical, given that at baseline these infants have difficult airways and failed extubation requires either re-intubation of an already complex airway with a fragile, recently osteotomized mandible, or adjunctive airway measures such as CPAP that may apply unwanted pressure to the surgical site. Thus, the goal is to plan extubation when the risk of failure is minimal. Currently, there is a void in the literature addressing the timing of extubation post-MDO and no objective sign of extubation readiness has been elucidated. This study describes a simple clinical pearl to assist in the evaluation of extubation readiness in these patients. Postoperatively, we obtain weekly radiographs to assess distractor stability and advancement, and to assess for the "Air Sign". The Air Sign describes a radiolucent space (air) visualized in the oropharynx on lateral radiographs, likely indicating that the tongue based airway obstruction has been relieved by mandibular advancement.

Le moment de l'extubation est très important après une opération de l'ostéogenèse par distraction mandibulaire, car ces nourrissons ont des voies respiratoires difficiles d'accès au départ, et une extubation malavisée entraîne soit la réintubation de voies respiratoires déjà difficiles à traverser alors que l'ostéotomie récente a fragilisé la mandibule, soit des interventions respiratoires d'appoint comme la CPAP, qui peuvent exercer une pression indésirable sur la zone opératoire. Ainsi, il faut planifier l'extubation au moment où le risque d'échec est minimal. À l'heure actuelle, les publications ne précisent pas le moment de l'extubation après l'ostéogenèse par distraction mandibulaire, et aucun signe objectif n'est fixé pour établir quand le patient y est prêt. La présente étude décrit une perle clinique simple pour contribuer à évaluer si ces patients sont prêts à être extubés. Après l'opération, les chercheurs ont obtenu des radiographies hebdomadaires pour évaluer la stabilité et l'avancement du distracteur, de même que le " signe de l'air ". Celui-ci décrit un espace translucide (air) visualisé dans l'oropharynx aux radiographies latérales, probablement indicateur du soulagement de l'obstruction des voies respiratoires par la langue grâce à l'avancement de la mandibule.

A Review of Frontal Orbital and Frontal Sinus Fractures and Associated Ocular Injuries - Level I Trauma Center - University Hospital Experience.

BACKGROUND: Traumatic frontal fractures result from high force injuries and can result in significant morbidity and mortality. The purpose of the current study is to evaluate our Montreal General Hospital (MGH) experience with frontal bone fractures. METHODS: A comprehensive review of our trauma database was performed. All adult patients (>18 years) presenting with a diagnosis of frontal sinus fracture were identified. A thorough retrospective electronic medical records search was performed and relevant data extracted. Specifically, all cases of ocular injury or sequelae were identified and an in-depth review was performed. RESULTS: Between 2008 and 2014, 10,189 trauma patients presented to the MUHC Level 1 trauma center. A total of 1277 patients presented with a facial fracture and 140 had a frontal sinus fracture. The mean age was 43.5 years, 90% were male and the mean hospitalization time was 16.2 days. A significant proportion of patients suffered concomitant craniomaxillofacial fractures including orbital (79%), maxillary (66%), nasal (64%), zygomaticomaxillary complex (34%), nasoorbitoethmoid (31%), Lefort types I-III (18%), and mandibular (8%). Associated cervical spine injuries were documented in 16% of patients. Ocular injuries were present in 30% of subjects. 26% of patients had some form of permanent sequelae from their trauma, mainly neurological. CONCLUSIONS: Due to the intimate association of the frontal bones with the brain and the orbits, frontal sinus fractures demand a sophisticated multidisciplinary craniofacial surgical approach. Given the high rate of ocular injury of 30% as well as severe systemic injuries, the authors propose a modified treatment algorithm for these complex cases.

Operative Time as the Predominant Risk Factor for Transfusion Requirements in Nonsyndromic Craniosynostosis Repair.

Despite recent advances in surgical, anesthetic, and safety protocols in the management of nonsyndromic craniosynostosis (NSC), significant rates of intraoperative blood loss continue to be reported by multiple centers. The purpose of the current study was to examine our center's experience with the surgical correction of NSC in an effort to determine independent risk factors of transfusion requirements. METHODS: A retrospective cohort study of patients with NSC undergoing surgical correction at the Montreal Children's Hospital was carried out. Baseline characteristics and perioperative complications were compared between patients receiving and not receiving transfusions and between those receiving a transfusion in excess or <25 cc/kg. Logistic regression analysis was carried out to determine independent predictors of transfusion requirements. RESULTS: A total of 100 patients met our inclusion criteria with a mean transfusion requirement of 29.6 cc/kg. Eighty-seven patients (87%) required a transfusion, and 45 patients (45%) required a significant (>25 cc/kg) intraoperative transfusion. Regression analysis revealed that increasing length of surgery was the main determinant for intraoperative (P = 0.008; odds ratio, 18.48; 95% CI, 2.14-159.36) and significant (>25 cc/kg) intraoperative (P = 0.004; odds ratio, 1.95; 95% CI, 1.23-3.07) transfusions. CONCLUSIONS: Our findings suggest increasing operative time as the predominant risk factor for intraoperative transfusion requirements. We encourage craniofacial surgeons to consider techniques to streamline the delivery of their selected procedure, in an effort to reduce operative time while minimizing the need for transfusion.

Routine Postoperative Admission to the Intensive Care Unit Following Repair of Nonsyndromic Craniosynostosis: Is it Necessary?

BACKGROUND: Cranial vault surgery for craniosynostosis is generally managed postoperatively in the intensive care unit (ICU). The purpose of the present study was to examine our center's experience with the postoperative management of otherwise healthy patients with nonsyndromic craniosynostosis (NSC) without routine ICU admission. METHODS: A retrospective cohort study of patients with NSC operated using a variety of vault reshaping techniques in our pediatric center between 2009 and 2017 was carried out. Patients with documented preexisting comorbidities that would have required admission to the ICU regardless of the surgical intervention were excluded. RESULTS: A total of 102 patients were included in the study. Postoperatively, 100 patients (98%) were admitted as planned to a general surgical ward following observation in the recovery room. Two patients (2%) required ICU admission due to adverse intraoperative events. There were no patients who required transfer to the ICU from the recovery area or surgical ward. Within the surgical ward cohort, 6 patients (6%) had minor postoperative complications that were readily managed on the surgical floor. Postoperative anemia requiring transfusion was the most common complication. CONCLUSION: The results from this study suggest that otherwise healthy patients with NSC undergoing cranial vault surgery can potentially be safely managed without routine admission to the ICU postoperatively. Key elements are proper preoperative screening, access to ICU should an adverse intraoperative event occur and necessary postoperative surgical care. The authors hope that this experience will encourage other craniofacial surgeons to reconsider the dogma of routine ICU admission for this patient population.

The Role of Preoperative Computed Tomography in Nonsyndromic Craniosynostosis.

BACKGROUND: There is currently no consensus on the utility of preoperative computed tomography (CT) in nonsyndromic craniosynostosis. This systematic review and meta-analysis examines the evidence available on the necessity of preoperative CT for the treatment of nonsyndromic craniosynostosis. METHODS: A comprehensive literature review of the National Library of Medicine (PubMed) database was performed. The following variables were analyzed: concordance of findings between clinical examinations and CT, incidental findings reported on imaging, and the effect of imaging on subsequent management. Concordance between clinical examination/CT and the presence of incidental findings were collected and displayed as descriptive data. The effect of imaging on subsequent diagnosis/management was analyzed by meta-analysis. RESULTS: Eleven studies met the inclusion criteria for a total of 728 patients. Overall, physical examination concordance with CT diagnosis was 97.9% (371/379). Overall, incidental findings led to additional imaging/workup in 1.79% of cases (5/278). The results of the meta-analysis revealed that, in the absence of alternative imaging modalities, CT scans significantly altered diagnosis or led to additional investigations in 12 cases (4.8%, 95% confidence interval = 3%-8%). Preoperative CT scans led to additional investigations in 5 cases and detected incomplete/wrong diagnoses in 7 cases. CONCLUSIONS: The results of the present meta-analysis support the use of preoperative CT scans for nonsyndromic craniosynostosis in the absence of alternative imaging modalities. The results also suggest that in properly selected patients, alternative imaging modalities may be appropriate, potentially obviating the need for CT scans.

The State of Technology in Craniosynostosis.

INTRODUCTION: Craniosynostosis, the premature fusion of ≥1 cranial sutures, is the leading cause of pediatric skull deformities, affecting 1 of every 2000 to 2500 live births worldwide. Technologies used for the management of craniofacial conditions, specifically in craniosynostosis, have been advancing dramatically. This article highlights the most recent technological advances in craniosynostosis surgery through a systematic review of the literature. METHODS: A systematic electronic search was performed using the PubMed database. Search terms used were "craniosynostosis" AND "technology" OR "innovation" OR "novel.' Two independent reviewers subsequently reviewed the resultant articles based on strict inclusion and exclusion criteria. Selected manuscripts deemed novel by the senior authors were grouped by procedure categories. RESULTS: Following review of the PubMed database, 28 of 536 articles were retained. Of the 28 articles, 20 articles consisting of 21 technologies were deemed as being novel by the senior authors. The technologies were categorized as diagnostic imaging (n = 6), surgical planning (n = 4), cranial vault evaluation (n = 4), machine learning (n = 3), ultrasound pinning (n = 3), and near-infrared spectroscopy (n = 1). CONCLUSION: Multiple technological advances have impacted the treatment of craniosynostosis. These innovations include improvement in diagnosis and objective measurement of craniosynostosis, preoperative planning, intraoperative procedures, communication between both surgeons and patients, and surgical education.

Surgery in Brazilian Health Care: funding and physician distribution.

Objective: to analyze demographic Brazilian medical data from the national public healthcare system (SUS), which provides free universal health coverage for the entire population, and discuss the problems revealed, with particular focus on surgical care. Methods: data was obtained from public healthcare databases including the Medical Demography, the Brazilian Federal Council of Medicine, the Brazilian Institute of Geography and Statistics, and the National Database of Healthcare Establishments. Density and distribution of the medical workforce and healthcare facilities were calculated, and the geographic regions were analyzed using the public private inequality index. Results: Brazil has an average of two physicians for every 1,000 inhabitants, who are unequally distributed throughout the country. There are 22,276 board certified general surgeons in Brazil (11.49 for every 100,000 people). The country currently has 257 medical schools, with 25,159 vacancies for medical students each year, with only around 13,500 vacancies for residency. The public private inequality index is 3.90 for the country, and ranges from 1.63 in the Rio de Janeiro up to 12.06 in Bahia. Conclusions: A significant part of the local population still faces many difficulties in accessing surgical care, particularly in the north and northeast of the country, where there are fewer hospitals and surgeons. Physicians and surgeons are particularly scarce in the public health system nationwide, and better incentives are needed to ensure an equal public and private workforce.

Objetivo: analisar dados demográficos do Sistema Único de Saúde (SUS) brasileiro, que promove cobertura de saúde universal a toda população, e discutir os problemas revelados, com particular ênfase nos cuidados cirúrgicos. Métodos: os dados foram obtidos a partir dos bancos de dados de saúde pública da Demografia Médica, do Conselho Federal de Medicina, do Instituto Brasileiro de Geografia e Estatística e do Cadastro Nacional dos Estabelecimentos de Saúde. A densidade e a distribuição do trabalho médico e dos estabelecimentos de saúde foram avaliadas, e as regiões geográficas foram analisadas usando o índice de desigualdade público-privado (IDPP). Resultados: o Brasil tem, em média, dois médicos por 1000 habitantes, que são desigualmente distribuídos no país. Tem 22.276 cirurgiões gerais certificados (11,49 por 100.000 habitantes). Existem no país 257 escolas de medicina, com 25.159 vagas por ano, e apenas cerca de 13.500 vagas de residência médica. O índice de desigualdade público-privado é de 3,90 para o país e varia de 1,63 no Rio de Janeiro até 12,06 na Bahia. Conclusão: uma parte significativa da população brasileira ainda encontra muitas dificuldades no acesso ao tratamento cirúrgico, particularmente na região norte e nordeste do país. Médicos e, particularmente, cirurgiões são escassos no sistema público de saúde e incentivos devem ser criados para assegurar uma força médica igual no setor público e no setor privado em todas as regiões do país.

Roteiros sexuais de transexuais e travestis e seus modos de envolvimento sexual-afetivo

As diversas facetas da sexualidade estão se tornando cada vez mais visíveis na sociedade atual e duas categorias que começam a ganhar espaço e visibilidade na contemporaneidade são as das transexuais e das travestis. Transexuais são pessoas que não se identificam com seus genitais biológicos (e suas atribuições socioculturais) podendo, às vezes, utilizar da cirurgia de transgenitalização para construir suas expressões de gêneros em consonância com seu bem estar biopsicossocial e político; enquanto travestis são pessoas que se identificam com as imagens e estilos de gêneros (masculinos e femininos) contrários ao seu sexo biológico (machos e fêmeas), que desejam e se apropriam de indumentárias e adereços dessas estéticas; realizam com frequência a transformação de seus corpos por meio da ingestão de hormônios e/ou da aplicação de silicone industrial, assim como, pelas cirurgias de correção estética e de implante de próteses, o que lhes permitem se situar dentro de uma condição agradável de bem estar biopsicossocial. Diversos estudos têm sido realizados, tendo essas pessoas como alvo. No entanto, são poucos os que focalizam as necessidades, desejos e fantasias das mesmas no que tange à esfera sexual. Este estudo tem como objetivo conhecer a vida sexual de travestis e transexuais, dando ênfase às suas práticas e roteiros sexuais. A pesquisa tem enfoque metodológico qualitativo e utiliza a teoria dos roteiros sexuais de Gagnon como referencial teórico. Os dados foram colhidos mediante a aplicação de entrevistas individuais semiestruturadas. Foram entrevistadas 15 pessoas, de 19 a 58 anos, entre travestis, transexuais que já realizaram a cirurgia de redesignação sexual e transexuais que não a realizaram. As entrevistas aconteceram em situação face a face e foram audiogravadas...(AU)

ês The many facets of sexuality are becoming more visible in society today and two categories that are gaining visibility in contemporary space are transsexuals and travestis. Transsexuals are people who do not identify with their biological genitalia (and their sociocultural assignments) and can, sometimes, use the reassignment surgery to build their expressions of gender in line with their biopsychosocial and political welfare; while travestis are people who identify with the images and styles of genders (masculine and feminine) contrary to their biological sex (male and female), who wish and appropriate costumes and props of such aesthetic; who perform often transformations on their bodies through ingestion of hormones and/or the application of industrial silicone, as well as by cosmetic surgery and prostheses implants, which allow them to be located within a pleasant welfare biopsychosocial condition. Several studies have been conducted with these people as their target. However, there are few that focus on the needs, desires and fantasies of this people regarding the sexual sphere. This study aims to know the sex lives of travestis and transsexuals, emphasizing their sexual practices and sexual scripts. The research has a qualitative methodological approach and uses the Gagnons theory of sexual scripts. Data were collected through the application of semistructured interviews. We interviewed 15 people, with ages between 19 and 58 years old, between travestis, transsexuals who already underwent sex reassignment surgery and transsexuals who didnt undergo the surgery. The interviews were carried out in face to face situation and were audio recorded. ..(AU)

Sistematização de curativos para o tratamento clínico das feridas / Systematization of dressing for clinical treatment of wounds", "_e": "n

O tratamento das feridas cutâneas inclui métodos clínicos e cirúrgicos, sendo o curativo um dos tratamentos clínicos mais frequentemente utilizados. Um vasto arsenal terapêutico composto por curativos passivos ou com princípios ativos é capaz de auxiliar na reparação do tegumento em diversas situações. Curativos visam a melhorar as condições do leito da ferida, podendo ser, em algumas ocasiões, o próprio tratamento definitivo, mas em muitas situações constituem apenas uma etapa intermediária para o tratamento cirúrgico. Curativos inteligentes e biológicos são hoje mais bem classificados como substitutos cutâneos e não serão considerados neste artigo. A escolha do curativo a ser utilizado deve ser baseada no conhecimento das bases fisiopatológicas da cicatrização e da reparação tecidual, sem nunca esquecer o quadro sistêmico do paciente.

The treatment of cutaneous wounds includes both medical and surgical methods; dressing is one of the most commonly used clinical treatments. An extensive therapeutic toolkit comprising passive dressings or dressings with active principles can help repair wounds in various situations. Dressings are used to improve the conditions of the wound bed and may occasionally be considered the definitive treatment, whereas in some cases, they may be considered an intermediate step to surgical treatment. Intelligent and biological wound dressings are currently classified as dermal substitutes and will not be discussed in this article. Dressings should be selected on the basis of knowledge of the pathophysiology of wound healing and tissue repair while keeping the systemic problems of the patient in mind.
