Treatment of a Diaphyseal Tibial Malunion with Use of the Clamshell Osteotomy.

Malunion, nonunion, congenital abnormalities, and osteometabolic diseases are the main causes of long bone deformities1. Although the exact incidence is unclear, it is estimated that about 10% of all fractures have some complication in terms of fracture-healing. In addition to the aesthetic impact, malunions generally substantially impair function and quality of life1. Every malunion is unique, and treatment is usually planned according to the degree of deformity and the postoperative expectations of the patient2. However, it is noteworthy that deformity correction usually requires a high degree of surgical expertise. Several techniques have been proposed over the years, and new techniques that utilize current technologies are available, such as computer-assisted single-cut osteotomy3. In 2009, Russell et al. proposed the clamshell technique for diaphyseal malunions4-6. This technique is our preferred treatment for diaphyseal malunions and acute fractures in the setting of a previous malunion or deformity. The following videos will thoroughly describe the steps to perform this useful and effective surgical technique for malunion correction. DESCRIPTION: The key principle of the "clamshell osteotomy" is to create a comminuted fracture at the malunion site and utilize an intramedullary rod as a template for deformity correction4,5. ALTERNATIVES: Multiple osteotomy types and fixation methods are currently available for diaphyseal malunion correction. Among the osteotomies, opening or closing wedge, uniplanar, multiplanar, oblique, and dome methods may be utilized. In addition, several fixation methods can be utilized, including plates and screws, intramedullary rods, and external fixators2,6. RATIONALE: The clamshell technique is a useful and effective treatment option for diaphyseal malunions of the lower extremity. The ability to utilize an intramedullary nail as a template for deformity correction makes the procedure simpler than previously described techniques, which require perfect preoperative planning to avoid over- and undercorrection. The versatility of this procedure justifies its incorporation into the therapeutic arsenal for treatment of complex diaphyseal malunions. EXPECTED OUTCOMES: To our knowledge, all previously reported cases utilizing the clamshell osteotomy have resulted in positive outcomes4-6. Russell et al. presented a case series of 10 patients with posttraumatic diaphyseal malunions (4 femoral and 6 tibial), in which all patients showed coronal and sagittal-plane correction to within 4°, limb-length inequality correction to within 2 cm, and complete correction of translation, rotation, and joint-line orientation angles4. In addition, all osteotomies healed uneventfully. The reported complications included broken interlocking screws in 1 case, need for dynamization in 1 case, and superficial wound dehiscence in 2 cases (1 of which required surgical debridement). Pires et al. presented 4 cases of clamshell osteotomies performed for the treatment of acute fractures in the setting of a previous malunion. All osteotomies healed by 15 months (mean time to healing [and standard deviation], 6.8 ± 4.4)6. One of these 4 cases was a Gustilo-Anderson grade-IIIB open fracture that required muscle flap coverage and a subsequent Hernigou procedure6. When discussing treatment options with patients, it is important to clarify that there is currently no clear best technique to treat complex malunions; however, the clamshell osteotomy is a simpler procedure compared with others that have previously been described and has the benefits of quick rehabilitation and good deformity correction without the drawbacks of an external fixator4-6. IMPORTANT TIPS: Preserve the blood supply in the opposite cortex.Close the fascia before reaming the medullary canal.Do not ream the osteotomy site.Be sure to perform a bicortical osteotomy.Create a stable construct.

The hidden risk of ionizing radiation in the operating room: a survey among 258 orthopaedic surgeons in Brazil.

BACKGROUND: This study aims to assess orthopaedic surgeon knowledge in Brazil about ionizing radiation and its health implications on surgical teams and patients. METHODS: A 15-question survey on theoretical and practical concepts of ionizing radiation was administered during the 23rd Brazilian Orthopaedic Trauma Association annual meeting. The survey addressed issues within orthopedic surgery, such as radiation safety concepts, protection, exposure, as well as the participant gender. Participants were either orthopedic surgeons or orthopedic surgery residents working at institutions in Brazil. RESULTS: One thousand surveys were distributed at the moment of the meeting registration, and 258 were answered completely (25.8% response rate). Only 5.8% of participants used basic radiation protection equipment; 47.3% used a dosimeter; 2.7% reached the annual maximum permissible radiation dose; 10.5% knew the period of increased risk to fetal gestation; 5.8% knew the maximum permissible radiation dose during pregnancy; 58.5% knew that the hands, eyes, and thyroid are the most exposed areas and at greater risk of radiation-related lesions; 25.2% knew the safe distance from a radiation-emitting tube is 3 m or more; 44.2% knew the safest positioning of the radiation-emitting tube; 25.2% knew that smaller tubes emit greater radiation at the entrance dose to magnify the image; and 55.4% knew that the surgery team receives more scattered radiation in surgical procedures performed on obese patients. CONCLUSION: This study revealed inadequate theoretical and practical knowledge about radiation exposure among orthopaedic surgeons in Brazil. Only a minority of orthopaedic surgeons used basic radiation protection equipment. No significant differences in knowledge were found when comparing all orthopedic surgery specialties. Our findings indicate an urgent need for education to increase knowledge among orthopaedic surgeons about the hazards of ionizing radiation. Personal protection and implementation of the ALARA (as low as reasonably achievable) protocol in daily practice are important behaviors to prevent the harmful effects of ionizing radiation.

Technique and results of the first six cases of anal sphincteroplasty with Deoti's flap for complex anatomical deformity of the perineum / Técnica e resultados dos primeiros seis casos de esfincteroplastia anal com retalho Deoti para deformidade anatômica complexa do períneo

ABSTRACT Objectives: Anal sphincteroplasty with Deoti's flap is a recently published procedure for the treatment of fecal incontinence with severe perineal deformity. The aim of this study is to report six cases of patients, analyzing their results in fecal incontinence questionnaires and proposing a new scale to better assess our technique's main objective, the reconstruction of the perianal anatomy. Methods: Six patients were submitted to anal sphincteroplasty with Deoti's flap and follow-up was performed every six months. Functional results and Quality of Life were measured by Wexner Score and Fecal Incontinence Quality of Life Scale, respectively. Results: All operations were carried out without failure to perform Deoti's flap rotation. The sample presented medians of 18.5 and 3.5 on Wexner Score, before and after surgery, respectively. In the Fecal Incontinence Quality of Life Scale, the medians before and after surgery are, respectively, 1.75 and 3.35 (Scale 1), 1.54 and 2.60 (Scale 2), 2.35 and 3.28 (Scale 3), 1.49 and 3.33 (Scale 4). The p-values were 0.0173 for Wexner Score and 0.0260, 0.0411, 0.0368 and 0.0952 for Scales 1, 2, 3 and 4 of Fecal Incontinence Quality of Life Scale, respectively. All patients presented sustained improvement in Wexner Score and in quality of life questionnaire (in all scales of Fecal Incontinence Quality of Life Scale). Conclusions: Deoti's surgical flap with sphincteroplasty successfully reconstructs complex anatomical deformities of the perineum. Current questionnaires to assess fecal incontinence may not evaluate properly the anatomical result of the technique, thus we propose a visual scale. In addition, sphincteroplasty with Deoti's flap may have longer-term outcomes in functional results than sphincteroplasty alone.

RESUMO Objetivos: A esfincteroplastia anal com retalho Deoti é um procedimento publicado recentemente para o tratamento de deformidade perineal grave. O objetivo deste estudo é relatar seis pacientes, analisando seus resultados em questionários de incontinência fecal e propondo uma nova escala para avaliar melhor o objetivo principal da nossa técnica, a reconstrução da anatomia perianal. Métodos: Seis pacientes foram submetidos à esfincteroplastia anal com retalho de Deoti e o acompanhamento foi realizado a cada seis meses. Os resultados funcionais e a qualidade de vida foram medidos pelas Escalas Wexner Score e FIQL, respectivamente. Resultados: Não houve falhas na rotação do retalho Deoti. A amostra apresentou medianas de 18,5 e 3,5 na Wexner Score, antes e depois da cirurgia, respectivamente. Na Escala FIQL, as medianas antes e depois da cirurgia são, respectivamente, 1,75 e 3,35 (Escala 1); 1,54 e 2,60 (Escala 2); 2,35 e 3,28 (Escala 3); 1,49 e 3,33 (Escala 4). Os valores de p foram 0,0173 para Wexner Score e 0,0260; 0,0411; 0,0368 e 0,0952 para Escalas 1; 2; 3 e 4 de FIQL, respectivamente. Todos os pacientes apresentaram melhora sustentada na pontuação de Wexner e no questionário de qualidade de vida (em todas as escalas do FIQL). Conclusões: O retalho de Deoti com esfincteroplastia reconstrói com sucesso as deformidades anatômicas complexas do períneo. Os questionários atuais para avaliar a incontinência fecal podem não avaliar adequadamente o resultado anatômico da técnica, por isso propomos uma escala visual. Além disso, a esfincteroplastia com retalho de Deoti pode apresentar resultados funcionais mais duradouros do que a esfincteroplastia isolada.

Fecal incontinence and quality of life assessment through questionnaires / Avaliação da incontinência fecal e impacto na qualidade de vida por questionários

ABSTRACT Background: Fecal incontinence causes a big impact on patient's quality of life. Our study analyzed the main questionnaires about fecal incontinence available internationally, aiming to delineate vantages and limitations of these instruments and their application, to mention the cultural aspects involved in the process of development and validation, as well as to suggest a reflection about the complexity of this matter. Results: Four of the instruments (Pescatori score, FISI, MSKCC bowel function instrument, and LARS score) do not include quality of life, working only as diagnostic tools. Two others, 'Jorge and Wexner Fecal Incontinence score', and 'St Marks' Fecal incontinence grading system' can diagnose and grade fecal incontinence, however they are very subtle in assessing quality of life. The 'EORTC Colorectal Cancer-specific', on the other hand, focuses exclusively on quality of life. Although the 'FIQL' questionnaire assesses quality of life related to fecal incontinence, it does not measure leakage. Lastly, the 'RAFIS' assesses both aspects but too superficially. Conclusion: None of the questionnaires analyzed were able to simultaneously assess both fecal incontinence and quality of life successfully. Furthermore, the concepts related to fecal incontinence have different meanings depending on the cultural and psychosocial context. These differences are even greater when individuals of developed countries like the ones where these questionnaires were developed are compared to the ones of developing countries, such as Brazil, which makes its very hard for these instruments to be used universally.

RESUMO Contexto: A incontinência anal acarreta grande impacto na qualidade de vida (QV) dos pacientes. Nosso estudo analisou os principais questionários sobre o tema disponíveis na literatura internacional, visando delinear vantagens e limitações desses instrumentos e de sua correta aplicação, bem como citar os aspectos culturais envolvidos no processo de sua criação e validação, e sugerir uma reflexão sobre a complexidade do tema. Métodos: Nessa revisão assistemática, utilizamos três bases de dados eletrônicas (MEDLINE, LILACS, e DeCS) para encontrar os 9 questionários mais utilizados no mundo, e palavras-chave relacionadas. Resultados: Quatro dos instrumentos estudados (Pescatori score, FISI, MSKCC bowel function instrument, e o LARS score) não abordam QV, funcionando apenas para diagnóstico. Outros dois, o 'Jorge and Wexner FI score', e o 'St Marks' FI grading system' diagnosticam e graduam bem a incontinência, porém apenas avaliam brevemente a QV. O 'EORTC Colorectal Cancer-specific', por sua vez, foca exclusivamente na QV. O questionário 'FIQL' apesar de conseguir avaliar a QV relacionada à função intestinal, não avalia vazamentos. Por fim, o 'RAFIS' avalia de forma muito simplificada esses aspectos. Conclusão: Nenhum dos questionários analisados se mostrou eficiente na avaliação simultânea da incontinência e da QV. Além disso, os conceitos que envolvem incontinência anal apresentam significados diferentes dependendo do contexto cultural e psicossocial. Essas diferenças são ainda maiores quando se comparam indivíduos dos países desenvolvidos onde esses questionários foram desenvolvidos, com os de países subdesenvolvidos como o Brasil, dificultando sua aplicação de forma universal.

Viruses vector control proposal: genus Aedes emphasis

Abstract The dengue fever is a major public health problem in the world. In Brazil, in 2015, there were 1,534,932 cases, being 20,320 cases of severe form, and 811 deaths related to this disease. The distribution of Aedes aegypti, the vector, is extensive. Recently, Zika and Chikungunya viruses had arisen, sharing the same vector as dengue and became a huge public health issue. Without specific treatment, it is urgently required as an effective vector control. This article is focused on reviewing vector control strategies, their effectiveness, viability and economical impact. Among all, the Sterile Insect Technique is highlighted as the best option to be adopted in Brazil, once it is largely effectively used in the USA and Mexico for plagues related to agribusiness.

Acute esophageal necrosis.

Acute esophageal necrosis (AEN) or "black esophagus" is a rare condition presented by patients with critical state of health and characterized by a darkened esophagus, usually the distal third, in upper digestive endoscopy. The main clinical manifestation is upper gastrointestinal bleeding and there may be abdominal pain, dysphagia, nausea, vomiting, fever and syncope associated. The diagnosis depends on clinical suspicion and performing endoscopy, the biopsy not being required. In this article we present a case of a patient who had lots of comorbidities and developed AEN during a post-operative period, and discuss the importance of AEN in an increasingly ageing population.
