Gupta Perioperative Risk for Myocardial Infarction or Cardiac Arrest Score is a Long-Term Cardiovascular Risk Predictor After Aortoiliac Revascularization.

BACKGROUND: Gupta Perioperative Risk for Myocardial Infarction or Cardiac Arrest (MICA) is a validated self-explanatory score applied in cardiac or noncardiac surgeries. This study aims to assess the predictive value of the MICA score for cardiovascular events after aortoiliac revascularization. METHODS: This prospective cohort underwent elective aortoiliac revascularization between 2013 and 2021. Patients' demographic, clinical characteristics, and outcomes were registered. The patients were divided into 2 groups according to the MICA score using optimal binning. Survival analysis to test for time-dependent variables and multivariate Cox regression analysis for independent predictors were performed. RESULTS: This study included 130 patients with a median follow-up of 55 months. Preoperative MICA score was ≥6.5 in 41 patients. MICA ≥6.5 presented a statistically significant association, with long-term occurrence of acute heart failure (HR = 1.695, 95% CI 1.208-2.379, P = 0.002), major adverse cardiovascular events (HR = 1.222, 95% CI 1.086-1.376, P < 0.001), and all-cause mortality (HR = 1.256, 95% CI 1.107-1.425, P < 0.001). Multivariable Cox regression confirmed MICA as a significant independent predictor of long-term major adverse cardiovascular events (aHR = 1.145 95% CI 1.010-1.298, P = 0.034) and all-cause mortality (aHR = 1.172 95% CI 1.026-1.339, P = 0.020). CONCLUSIONS: The MICA score is a quick, easy-to-obtain, predictive tool in identifying patients with a higher risk of postaortoiliac revascularization cardiovascular events, such as acute heart failure, major adverse cardiovascular events, and all-cause mortality. Additional research for the validation of the MICA score in the context of aortoiliac revascularization and specific interventions is necessary.

Acurácia do escore de referência endoscópico para esofagite eosinofílica em crianças / Accuracy of the eosinophilic esophagitis endoscopic reference score in children

ABSTRACT Background: To assess the efficacy of applying the endoscopic reference score for EoE (EREFS) in children with symptoms of esophageal dysfunction naïve to proton pump inhibitor (PPI) therapy. Methods: An observational cross-sectional study was conducted by reviewing reports and photographs of upper gastrointestinal endoscopies (UGE) and esophageal biopsies of patients with symptoms of esophageal dysfunction. Patients who were treated with PPI or had other conditions that may cause esophageal eosinophilia were excluded. Results: Of the 2,036 patients evaluated, endoscopic findings of EoE were identified in 248 (12.2%) and more than one abnormality was observed in 167 (8.2%). Among all patients, 154 (7.6%) presented esophageal eosinophilia (≥15 eosinophils per high power field) (P<0.01). In this group, 30 patients (19.5%) had normal endoscopy. In patients with EoE, edema (74% vs 6.5%, P<0.01) and furrows (66.2% vs 2.4%, P<0.01) were more prevalent than in the control group. Association of edema and furrows was more frequent in patients with EoE than in the control group (29.2% vs 1.6%, P<0.01, OR=24.7, CI=15.0-40.5). The presence of more than one endoscopic finding had sensitivity of 80.5%, specificity of 93.4%, positive predictive value (PPV) of 50%, negative predictive value (NPV) of 98.3%, and accuracy of 92.4%. Conclusion: In conclusion, this study showed that endoscopic features suggestive of EoE had high specificity and NPV for diagnosing EoE in children naïve to PPI therapy. These findings highlight the importance of the EREFS in contributing to early identification of inflammatory and fibrostenosing characteristics of EoE, making it possible to identify and to avoid progression of the disease.

RESUMO Contexto: Avaliar a eficácia da aplicação do escore de referência endoscópico para EoE (EREFS) em crianças com sintomas de disfunção esofágica sem tratamento prévio com inibidores da bomba de prótons (IBP). Métodos: Foi realizado um estudo transversal observacional por meio de revisão de laudos e fotos de endoscopia digestiva alta (EDA) e biópsias de esôfago de pacientes com sintomas de disfunção esofágica. Pacientes tratados com IBP ou com outras condições que podem causar eosinofilia esofágica foram excluídos. Resultados: Dos 2.036 pacientes avaliados, os achados endoscópicos de EoE foram identificados em 248 (12,2%) e mais de uma anormalidade foi observada em 167 (8,2%). Entre todos os pacientes, 154 (7,6%) apresentaram eosinofilia esofágica (≥15 eosinófilos por campo de grande aumento) (P<0,01). Nesse grupo, 30 pacientes (19,5%) apresentaram endoscopia normal. Em pacientes com EoE, edema (74% vs 6,5%, P<0,01) e linhas verticais (66,2% vs 2,4%, P<0,01) foram mais prevalentes quando comparados ao grupo controle. A associação de edema e linhas verticais foi mais frequente em pacientes com EoE do que no grupo controle (29,2% vs 1,6%, P<0,01, OR=24,7, IC=15,0-40,5). A presença de mais de um achado endoscópico teve sensibilidade de 80,5%, especificidade de 93,4%, valor preditivo positivo de 50%, valor preditivo negativo de 98,3% e acurácia de 92,4%. Conclusão: Em conclusão, esse estudo mostrou que as características endoscópicas sugestivas de EoE apresentam especificidade e VPN elevados para o diagnóstico da enfermidade em crianças sem tratamento prévio com IBP. Estes achados reforçam a importância do EREFS em contribuir para a identificação precoce de características inflamatórias e fibroestenosantes, possibilitando identificar e evitar a progressão da doença.

Biological therapy, surgery, and hospitalization rates for inflammatory bowel disease: An observational Latin American comparative study between adults and pediatric patients.

OBJECTIVE: Compare the proportions of use of biological therapy, surgeries, and hospitalizations between adults and pediatric inflammatory bowel disease (IBD)-Crohn's disease (CD) and ulcerative colitis (UC)-patients. PATIENTS AND METHODS: Observational, retrospective, and multicenter study. Data were collected from all consecutive IBD patients seen as outpatients or admitted to hospital, during 2015-2021, in two IBD tertiary centers in a South Brazilian capital. Patients with unclassified colitis diagnosis were excluded from this study. Patients were classified as having CD or UC and sub-categorized as adult or pediatric according to age. Data were analyzed using frequency, proportion, Fisher's exact test, and Chi-square test. RESULTS: A total of 829 patients were included: 509 with CD (378 adults/131 pediatric) and 320 with UC (225/95). Among patients with CD, no differences were observed for proportions of use of biological therapy (80.2% in pediatric vs. 73.3% in adults; P=0.129), surgery (46.6% vs. 50.8%; P=0.419), or hospitalization (64.9% vs. 56.9%; P=0.122). In UC, significant differences were observed for biological therapy (40.0% vs. 28.0%; P=0.048) and hospitalization (47.4% vs. 24.0%; P<0.001). No significant difference was observed in surgery rates (17.9% vs. 12.4%; P=0.219). CONCLUSIONS: Biological therapy and incidence of hospitalization were greater among pediatric patients with UC, compared with adults; no difference was observed in the need for abdominal surgery. In CD, no significant difference was observed in the three main outcomes between the age groups.

Emergent Endovascular Repair For Primary Aortoenteric Fistula.

We report the case of a 64-year-old male with significant cardiac comorbidities who reported three episodes of gastrointestinal bleeding. In the third episode, he presented massive hematemesis, anaemia and hypotension. Despite a standard upper endoscopy, a computed tomography (CT) showed an infrarenal abdominal aortic aneurysm and densification of the aortic fat cover. A primary aortoenteric fistula, with acute bleeding and haemodynamic instability, was assumed, and an emergent endovascular repair was performed. Subsequent CT scans and endoscopies demonstrated control of the enteric lesion. After five months, there was no evidence of infection or rebleeding.

Intra- and interobserver agreement of histopathological findings in pediatric patients with eosinophilic esophagitis

Abstract Objective: To assess intra- and interobserver agreement among non-expert pathologists in identifying features of the eosinophilic esophagitis histologic scoring system (EoEHSS) in pediatric patients. Patients and methods: The authors used 50 slides from patients (aged 1-15 years; 72% male) with EoE. EoEHSS evaluates eosinophilic inflammation and other features including epithelial basal zone hyperplasia, eosinophilic abscesses, eosinophil surface layering, dilated intercellular spaces, surface epithelial alteration, dyskeratotic epithelial cells, and lamina propria fibrosis. Grade and stage of abnormalities are scored using a 4-point scale (0 normal; 3 maximum change). Four pathologists determined EoEHSS findings on two occasions. Intra- and interobserver agreement was assessed using Kappa (κ) statistics and intra-class correlation coefficients. Results: Intra- and interobserver agreement for the identification of eosinophil counts ≥ 15/high power field (HPF) was excellent, however varied when assessing additional features of the EoEHSS. For the more experienced pathologist, agreement for most EoEHSS items and the composite scores was substantial to excellent. For the less experienced pathologists, intraobserver agreement ranged from absent to substantial for individual features and ranged from moderate to substantial for the composite scores. Conclusion: Most items of the EoEHSS had substantial to excellent reliability when assessed by a pathologist experienced in the diagnosis of EoE but presented lower repeatability among less experienced pathologists. These findings suggest that specific training of pathologists is required for the identification of EoEHSS characteristics beyond eosinophil count, as these features are considered useful in the evaluation of response to treatment and correlation with clinical manifestations and endoscopic findings.

Mean Platelet Volume Predicts Restenosis After Carotid Endarterectomy.

BACKGROUND: Carotid restenosis following carotid endarterectomy (CEA) has a cumulative risk at 5-years up to 32%, which may impact the well-being of patients following CEA. Haematological parameters in the standard complete blood cell count (CBC) are emerging as potential biomarkers, but their application in CEA is scarce. The primary aim of this study was to investigate haematological markers for restenosis following CEA. The secondary aim was to characterize clinical risk factors for restenosis. METHODS: From January 2012 to January 2019, 151 patients who underwent CEA under regional anaesthesia due to carotid stenosis were selected from a prospectively maintained cohort database. Patients were included if a preoperative CBC was available in the 2 weeks preceding CEA. Multivariable analysis was performed alongside propensity score matching (PSM) analysis, using the preoperative CEA parameters, to reduce confounding factors between categories. RESULTS: The study group comprised 28 patients who developed carotid restenosis. The remaining 123 patients without restenosis composed the control group. Mean age of the patients did not differ significantly between groups (70.25 ± 8.05 vs. 70.32 ± 9.61 YO, P = 0.973), neither did gender (male gender 89.3% vs. 78.9%, P = 0.206). Regarding haematological parameters, only MPV remained statistically significant within multivariable analysis (1.855, aOR [1.174-2.931], P = 0.008), a result supported by PSM analysis (2.072, aOR [1.036-4.147], P = 0.042). CONCLUSIONS: MPV was able to predict restenosis 2 years after CEA. Thus, MPV can be incorporated into score calculations to identify patients at greater risk of restenosis, who could benefit from specific monitoring during follow-up. While results are promising, more research is necessary to corroborate them.

An audit of disseminated intravascular coagulation screen requests at an academic hospital laboratory in central South Africa.

INTRODUCTION: Disseminated intravascular coagulation (DIC) is a feared complication of various systemic illnesses. We aimed to evaluate the laboratory requesting practices of clinicians, especially concerning the laboratory parameters, included in the International Society of Thrombosis and Haemostasis (ISTH) DIC score. METHODS: A retrospective descriptive study was performed and included data from DIC screen requests analysed at Universitas National Health Laboratory Service (NHLS) laboratory, Bloemfontein, South Africa, for one calendar year. Laboratory request forms were analysed, recording the pretest diagnosis and whether the diagnosis was associated with DIC. Parameters of the DIC screen, prothrombin time, activated partial thromboplastin time, thrombin time, d-dimer and fibrinogen were used to calculate the ITSH DIC score and diagnose heparin contamination. The platelet count, currently not part of the DIC screen test set, was also recorded. RESULTS: A total of 778 DIC screen requests were processed. One hundred and eighty-three requests were excluded due to laboratory-defined rejection criteria, heparin contamination or for lacking an ISTH score parameter. Of the remaining 595 complete requests, 283 (47.7%) were laboratory-defined overt DIC. The pretest diagnosis was not predictive of either a positive or negative finding of overt DIC. The contribution of fibrinogen to assigning overt DIC was questionable. CONCLUSION: The number of DIC screen requests received highlights the need for laboratory evidence of DIC. To improve laboratory DIC testing, the authors suggest critical evaluation of the contribution of the pretest diagnosis and fibrinogen in a prospective study and adding the platelet count in our local DIC test set.

Endoscopic and histological characteristics in patients with eosinophilic esophagitis responsive and non-responsive to proton pump inhibitors / Características endoscópicas e histológicas em pacientes com esofagite eosinofílica responsiva e não responsiva aos inibidores de bomba de prótons

Abstract Objective: To compare endoscopic and histologic features of pediatric patients with eosinophilic esophagitis (EoE) responding to proton pump inhibitor (PPI) to those not responding to PPI. Methods: Endoscopic reports and photographs of patients with symptoms of esophageal dysfunction and ≥15 eosinophils per high-powered field (eos/hpf) in esophageal biopsies prior to PPI trial were reviewed. Patients were classified as responsive to PPI (PPIREoE) or non-responsive to PPI (PPINREoE) according to response totreatment (<15 eos/hpf) at second endoscopy after 8 weeks. Results: Of the 231 patients (72.3% male), 64 (27.7%) were responsive to the proton pump inhibitors. Edema (77.3% vs. 62.5%, p = 0.031) and vertical lines (69.5% vs. 51.6%, p = 0.014) were more frequent in PPINREoE patients. An eosinophil count in the mid-esophagus ≥ 35 eos/HPF (25.1% vs. 12.5%) was more frequent in these patients (p = 0.001). Those with eosinophil count < 15 eos/HPF in the mid-esophagus at the first endoscopy were more likely to respond to treatment with proton pump inhibitors compared to patients with 15-34 eos/HPF (p = 0.004, OR: 3.26, 95% CI: 1.46-7.24) and to patients with ≥ 35 eos/HPF (p = 0.006, OR: 3.20, 95% CI: 1.39-7.41). Conclusion: Edema and vertical lines at the endoscopy and a higher eosinophil count in the mid-esophagus were more frequent in patients who were non-responsive to proton pump inhibitors. As there were no significant differences in the other findings between the groups, it cannot be affirmed that these characteristics are sufficient to differentiate between PPINREoE and PPIREoE patients.

Resumo Objetivo: Comparar características endoscópicas e histológicas entre pacientes com esofagite eosinofílica responsiva (EoERIBP) e não responsiva (EoENRIBP) ao tratamento com inibidores de bomba de prótons. Métodos: Avaliados laudos e imagens endoscópicas de pacientes com sintomas de disfunção esofágica associados a contagem ≥ 15 eosinófilos por campo de grande aumento (eos/CGA) em biópsia do esôfago. Os pacientes foram classificados em responsivos (EoERIBP) ou não responsivos (EoENRIBP) aos inibidores de bomba de prótons conforme resposta ao tratamento na segunda endoscopia (< 15 eos/CGA) após 8 semanas. Resultados: Dos 231 pacientes (72,3% masculino), 64 (27,7%) foram responsivos aos inibidores de bomba de prótons. Edema (77,3% vs. 62,5%, p = 0,031) e linhas verticais (69,5% vs. 51,6%, p = 0,014) foram mais frequentes nos EoENRIBP. A contagem de eosinófilos em esôfago médio ≥ 35 eos/CGA (25,1% vs. 12,5%) foi mais frequente nesses pacientes (p = 0,001). Os que apresentaram contagem de eosinófilos < 15 eos/CGA no esôfago médio à primeira endoscopia apresentaram maior chance de responder ao tratamento com inibidores de bomba de prótons em comparação aos pacientes com 15-34 eos/CGA (p = 0,004; OR: 3,26; IC95%: 1,46-7,24) e aos pacientes com ≥ 35 eos/CGA (p = 0,006; OR: 3,20; IC95%: 1,39-7,41). Conclusão: Edema e linhas verticais à endoscopia e maior contagem de eosinófilos em esôfago médio foram mais frequentes nos pacientes não responsivos aos inibidores de bomba de prótons. Uma vez que não houve diferenças significativas nos outros achados entre os grupos, não se pode afirmar que essas características sejam suficientes para distinguir pacientes com EoENRIBP dos pacientes com EoERIBP.

Brazilian consensus statement on viscosupplementation of the knee (cobravi) / Consenso brasileiro de viscossuplementação do joelho (cobravi)

ABSTRACT Objective: The aim of this consensus statement on viscosupplementation is to serve as a reference document based on relevant literature and clinical experience in the treatment of knee osteoarthritis using an intra-articular injection of hyaluronic acid, covering key aspects such as clinical indications, effectiveness, and tolerability. Methods: A multidisciplinary panel including two sports medicine physicians, six orthopedists, four physiatrists, and two rheumatologists were selected based on their clinical and academic experience of viscosupplementation. Sixteen statements were prepared and discussed, after which a vote was held. Each member of the panel gave a score between 0 and 10 on a Likert scale, specifying their level of agreement with the statement. Results: The panel reached a consensus on several issues. Specifically, the panel agreed that the best indication is for mild to moderate knee arthrosis; prior or concomitant use of intraarticular triamcinolone hexacetonide may optimize the effect of hyaluronic acid; viscosupplementation should not be performed as an isolated procedure but in conjunction with other rehabilitative and pharmacological measures; viscosupplementation has analgesic, anti-inflammatory, and chondroprotective effects; and viscosupplementation is cost-effective. Conclusion: This consensus statement provides clear information and guidance for both individuals and payers. Level of evidence V, Consensus statement.

RESUMO Objetivo: O Consenso Brasileiro de Viscossuplementação visa gerar uma fonte referencial e consensual, a partir de levantamentos bibliográficos relevantes, do conhecimento teórico e da experiência clínica de especialistas de áreas afins para tratamento de viscossuplementação na osteoartrite do joelho, mitigando pontos críticos desse procedimento, como via de aplicação, indicação, eficácia e tolerabilidade. Métodos: Um painel multidisciplinar foi formado com dois médicos do esporte, seis ortopedistas, quatro fisiatras e dois reumatologistas, com base nas experiências clínica e acadêmica no uso da viscossuplementação. Foram elaboradas, discutidas e votadas 16 afirmativas. Cada membro do painel deu um valor entre zero e 10, em uma escala tipo Likert, especificando seu nível de concordância com a afirmação. Resultados: O painel chegou a um consenso sobre diversos aspectos da viscossuplementação, com destaque para as seguintes afirmativas: a melhor indicação é para artrose de joelhos leve a moderada; o uso prévio ou concomitante de hexacetonido de triancinolona intra-articular pode otimizar o efeito do ácido hialurônico; a viscossuplementação não deve ser realizada como procedimento isolado no tratamento da OA, mas em conjunto com outras medidas reabilitadoras e farmacológicas; promove efeito analgésico; anti-inflamatório; condroprotetor; e é custo-efetiva. Conclusão: Este consenso traz informações claras e servirá, como guia tanto para médicos quanto para as fontes pagadoras. Nível de evidência V, Consenso de especialistas.

Eosinophilic esophagitis-Where are we today? / Esofagite eosinofílica - Qual é a nossa posição atual?

Abstract Objective: The objective of this review is to provide an overview of the practical diagnostic and therapeutic approaches to eosinophilic esophagitis and to increase the visibility of the disease among pediatricians. Sources: A search of the MEDLINE, Embase, and CINAHL databases and recent consensus statements and guidelines were performed. Summary of the findings: The definition of eosinophilic esophagitis is based on symptoms and histology. It is important to rule out other diseases associated with esophageal eosinophil-predominant inflammation. It is not yet clear whether the increased prevalence is due to a real increase in incidence or a result of increased awareness of the disease. Various options for management have been used in pediatric patients, including proton pump inhibitors, dietary restriction therapies, swallowed topical steroids, and endoscopic dilations. More recently, proton pump inhibitor-responsive esophageal eosinophilia and eosinophilic esophagitis have been contemplated on the same spectrum, and proton pump inhibitors should be considered the initial step in the treatment of these patients. Conclusions: Eosinophilic esophagitis is a relatively new disease with a remarkable progression of its incidence and prevalence in the past two to three decades, and diagnostic criteria that are constantly evolving. It is important to better understand the pathogenesis of the disease, the predisposing factors, the natural history, and the categorization of varying phenotypes to develop diagnostic and therapeutic strategies that meet the clinical needs of patients.

Resumo Objetivo: Fornecer uma visão geral do diagnóstico e do tratamento da esofagite eosinofílica na prática clínica e aumentar a visibilidade da doença entre os pediatras. Fontes dos dados: Foi feita uma busca na literatura relevante nos bancos de dados Medline, Embase, CINAHL e consensos e diretrizes recentes foram revisados. Síntese dos dados: A definição de esofagite eosinofílica é baseada nos sintomas e na histologia. É importante excluir outras doenças associadas com inflamação esofágica predominantemente eosinofílica. Ainda não está claro se o aumento na prevalência é devido a um real aumento da incidência ou se é o resultado da maior suspeição diagnóstica. Várias opções para tratamento, inclusive inibidores de bomba de prótons, restrições dietéticas, esteroides tópicos deglutidos e dilatações endoscópicas têm sido usadas em pacientes pediátricos. Mais recentemente a eosinofilia esofágica responsiva a inibidores de bomba de prótons e a esofagite eosinofílica têm sido contempladas no mesmo espectro e os inibidores de bomba de prótons devem ser considerados como opção inicial no tratamento desses pacientes. Conclusões: A esofagite eosinofílica é uma doença relativamente nova com uma notável progressão da incidência e prevalência nas últimas 2-3 décadas e critérios diagnósticos estão em evolução constante. É importante entender melhor a patogênese dessa doença, os fatores predisponentes, a história natural e a categorização dos diferentes fenótipos para desenvolver estratégias diagnósticas e terapêuticas que vão ao encontro das necessidades clínicas dos pacientes.

[Referral and coordination of healthcare from primary care to angiology and vascular surgery - a center's experience]. / Referenciação e articulação de cuidados entre cuidados de saúde primários e cuidados hospitalares de angiologia e cirurgia vascular ­ experiência de um centro.

INTRODUCTION: Minimally invasive revascularization of the left anterior descending coronary artery has gained popularity. Recently, the emergence of new surgical instruments and the improvement of the technique, allowed its use by routine. Its use in Heart Team allows excellent results. Our aim is to present the results of patients undergoing this technique in our center. METHODS: Retrospective study of patients submitted to minimally invasive revascularization of the left anterior descending coronary artery at our center. RESULTS: We identified 14 patients. The mean age was 67 years old. In the total of the procedures, 79% were elective and 21% urgent. The ventricular function was preserved in 86% of the patients. In the preoperative catheterization, 64% of the patients showed single disease of the anterior descending coronary artery, 29% had trunk lesions and 3 vessels and 7% had lesion of 2 vessels. The mean Euroscore II was 4.8%. The mean time of surgery was 103 minutes with a mean blood loss of 250mL. The main complications were wound dehiscence and revision of hemostasis. The mean hospitalization rate was 6.2 days. The hospital survival rate was 100%. CONCLUSION: Minimally invasive revascularization allows coronary artery bypass grafting with the best conduit. Revascularization may be total in single disease of the left anterior descending artery, or in case of multivessel disease, achieved with hibrid revascularization, with angioplasty of the remaining vessels. This technique has shown to be promising and safe, being the discussion in Heart Team of the patient candidates essential for achieving the best results.

Recentemente, o surgimento de novos instrumentos cirúrgicos e aperfeiçoamento da técnica, permitiu que seja utilizada por rotina. O seu uso em Heart Team permite excelentes resultados. O nosso objetivo é apresentar os resultados do nosso centro, dos doentes submetidos a esta técnica. Métodos: Estudo retrospetivo dos doentes submetidos a revascularização minimamente invasiva da artéria coronária descendente anterior, no nosso centro. Resultados: Foram identificados 14 doentes. A média de idade foi de 67 anos. Do total de procedimentos, 79% foram eletivos e 21% urgentes. A função ventricular encontrava-se conservada em 86% dos doentes. No cateterismo pré-operatório, 64% dos doentes apresentou doença única da descendente anterior, 29% lesão do tronco e 3 vasos e 7% lesão de 2 vasos. O Euroscore II médio foi de 4,8%. O tempo médio de cirurgia foi 103 minutos, com uma perda média de sangue de 250mL. As principais complicações foram deiscência da ferida operatória e revisão da hemóstase. A média de internamento foi de 6,2 dias. A taxa de sobrevida hospitalar foi 100%. Conclusão: A cirurgia minimamente invasiva permite a revascularização da artéria coronária mais importante, com o melhor conduto. A revascularização pode ser total, em doença única da descendente anterior, ou em caso de doença multivaso, conseguida com revascularização híbrida, com angioplastia dos restantes vasos. Esta técnica tem-se mostrado promissora e segura, sendo a discussão dos doentes candidatos em Heart Team, essencial para obter os melhores resultados.

Pediatrician's knowledge on the approach of functional constipation / Conhecimento do pediatra sobre o manejo da constipação intestinal funcional

Abstract Objective: To evaluate the pediatrician's knowledge regarding the diagnostic and therapeutic approach of childhood functional constipation. Methods: A descriptive cross-sectional study was performed with the application of a self-administered questionnaire concerning a hypothetical clinical case of childhood functional constipation with fecal incontinence to physicians (n=297) randomly interviewed at the 36th Brazilian Congress of Pediatrics in 2013. Results: The majority of the participants were females, the mean age was 44.1 years, the mean time of professional practice was 18.8 years; 56.9% were Board Certified by the Brazilian Society of Pediatrics. Additional tests were ordered by 40.4%; including abdominal radiography (19.5%), barium enema (10.4%), laboratory tests (9.8%), abdominal ultrasound (6.7%), colonoscopy (2.4%), manometry and rectal biopsy (both 1.7%). The most common interventions included lactulose (26.6%), mineral oil (17.5%), polyethylene glycol (14.5%), fiber supplement (9.1%) and milk of magnesia (5.4%). Nutritional guidance (84.8%), fecal disimpaction (17.2%) and toilet training (19.5%) were also indicated. Conclusions: Our results show that pediatricians do not adhere to current recommendations for the management of childhood functional constipation, as unnecessary tests were ordered and the first-line treatment was not prescribed.

Métodos: Estudo transversal descritivo com amostra constituída de médicos (n=297) entrevistados no 36º Congresso Brasileiro de Pediatria de 2013. Foi usado um questionário autoadministrado referente a um caso clínico hipotético de constipação intestinal. Resultados: Foi observada maior proporção de pediatras do sexo feminino, média de 44,1 anos, tempo de formação médio de 18,8 anos, 56,9% portadores de título de especialista pela Sociedade Brasileira de Pediatria. Exames complementares foram solicitados por 40,4%, a radiografia abdominal foi o mais requisitado (19,5%), seguido por enema opaco (10,4%), exames laboratoriais (9,8%), ultrassonografia de abdome (6,7%), colonoscopia (2,4%), manometria e biópsia (ambas 1,7%). Para o manejo foi sugerida a prescrição de lactulose (26,6%), óleo mineral (17,5%), polietilenoglicol (14,5%), suplemento de fibras (9,1%) e leite de magnésia (5,4%). Orientação alimentar (84,8%), desimpactação fecal (17,2%) e treinamento de toalete (19,5%) também foram indicadas. Conclusões: Evidencia-se uma discordância entre o manejo sugerido pelos pediatras e a conduta preconizada pela literatura disponível atualmente, uma vez que foram solicitados exames complementares desnecessários e não foi recomendada a orientação terapêutica considerada de primeira linha.

Estudio multicéntrico sobre la epidemiologia de la Esofagitis Eosinofílica Pediátrica en América Latina / Multicenter study on the epidemiology of pediatric eosinophilic esophagitis in latinamerica

Objetivo: Evaluar las características epidemiológicas de un grupo de pacientes pediátricos con esofagitis eosinofílica (EEo) y las modalidades de tratamiento empleadas en Latinoamérica. Pacientes y métodos: Estudio multicéntrico, observacional, transversal. Se aplicó una encuesta a 36 Centros de Gastroenterología y Endoscopia Pediátrica de 10 países latinoamericanos con la finalidad de obtener información socio-demográfica y datos sobre el tratamiento utilizado para el manejo de los casos evaluados durante el periodo 2014-2016. Resultados: 372 casos de EEo pediátrica fueron evaluados durante el periodo 2014-2016 y 108 casos (29%) correspondieron al trimestre Abril-Junio 2016. 46,72% de los casos pertenecían al grupo de edad escolar y 71,8% consultaron por disfagia. 87,2% de los pacientes fueron manejados con dieta, 55,3% esteroides deglutidos (12,8% en monoterapia) y 6% recibió montelukast. No hubo reporte de pacientes en terapia con agentes biológicos. Conclusiones: los resultados sugieren un predominio del sexo masculino con una mayor incidencia de la enfermedad en la edad escolar y la adolescencia. Las manifestaciones clínicas más frecuentes son disfagia, vómitos y síntomas de reflujo gastroesofágico. El tratamiento más indicado por los especialistas en América Latina es la dieta seguido del uso de esteroides deglutidos. Los IBP también son ampliamente utilizados como terapia coadyuvante. Un estudio de prevalencia a nivel continental es necesario para evaluar el comportamiento de la enfermedad en diferentes regiones de América Latina.

Aims: To evaluate epidemiological features of pediatric patients with eosinophilic esophagitis in Latinamerica and therapeutical options indicated by pediatric gastroenterologists in our continent. Patients and methods: multicenter, observational, transversal study. 36 Centers of Pediatric Gastroenterology and Endoscopy from 10 latinamerican countries participated giving clinical and sociodemographic information about pediatric patients with EoE diagnosed and treated during the last two years (study period). Results: 372 cases of pediatric EoE were evaluated during period 2014-2016 (108 cases were evaluated during trimester April-June 2016). 46,72% of cases were school age children, with dysphagia been the main clinical symptom in 71,8% of patients. 87,2% of patients received diet as a main indication of treatment, 55,3% received swallowed steroids (12,8% as monotherapy) and 6% were treated with montelukast among others. There were no reports of patients under treatment with biological drugs. Conclusions: epidemiological features of our study group suggest a higher prevalence of pediatric EoE in male school age children and adolescents. Most frecuent clinical symptoms are dysphagia, vomiting and gastroesophageal reflux symptoms. Treatment is based mainly on diet and swallowed steroids. A continental prevalence study is necessary to evaluate the behavior of the disease in different regions of Latinamerica.

Pediatrician's knowledge on the approach of functional constipation. / Conhecimento do pediatra sobre o manejo da constipação intestinal funcional.

OBJECTIVE: To evaluate the pediatrician's knowledge regarding the diagnostic and therapeutic approach of childhood functional constipation. METHODS: A descriptive cross-sectional study was performed with the application of a self-administered questionnaire concerning a hypothetical clinical case of childhood functional constipation with fecal incontinence to physicians (n=297) randomly interviewed at the 36th Brazilian Congress of Pediatrics in 2013. RESULTS: The majority of the participants were females, the mean age was 44.1 years, the mean time of professional practice was 18.8 years; 56.9% were Board Certified by the Brazilian Society of Pediatrics. Additional tests were ordered by 40.4%; including abdominal radiography (19.5%), barium enema (10.4%), laboratory tests (9.8%), abdominal ultrasound (6.7%), colonoscopy (2.4%), manometry and rectal biopsy (both 1.7%). The most common interventions included lactulose (26.6%), mineral oil (17.5%), polyethylene glycol (14.5%), fiber supplement (9.1%) and milk of magnesia (5.4%). Nutritional guidance (84.8%), fecal disimpaction (17.2%) and toilet training (19.5%) were also indicated. CONCLUSIONS: Our results show that pediatricians do not adhere to current recommendations for the management of childhood functional constipation, as unnecessary tests were ordered and the first-line treatment was not prescribed.

[Early type I Endoleak after Endovascular Management of an Aorto-esophageal Fistula]. / Endoleak Tipo I Precoce no Tratamento Endovascular de Fístula Aorto-Esofágica.

OBJECTIVE: Presentation of a clinical case of an aorto-esophageal fistula secondary to thoracic aorta pseudoaneurysm, complicated by early type Ia endoleak after endovascular repair. CLINICAL CASE: A 64 years old male patient, with a history of arterial hypertension, smoking, alcohol abuse and ischemic heart disease with previous coronary revascularization was observed because of chest pain and abundant hematemesis, with Angio-CT revealing a 77mm pseudoaneurysm of the descending thoracic aorta, close to the left subclavian artery, with mass effect on the esophagus and trachea and signs of fistulization. He was proposed to endovascular repair with sealing in zone 2 of the aortic arch after building a left carotid-subclavian bypass. In the first 24 hours there were two episodes of massive hematemesis, with new Angio-CT revealing a early distal migration of the prosthesis, conditioning a type Ia endoleak. A carotid-carotid right-left bypass with left carotid ligation was performed and a new endoprosthesis was implanted in the origin of the brachycephalic trunk (zone 1). The final angiography showed aneurysm exclusion with permeability of the supra-aortic trunks. Later contrasted esophageal examination and endoscopy revealed an ulcer of the posterior left lateral wall with clot suggestive of fistula, and an esophageal prosthesis was successfully implanted. It held seven days of antibiotic therapy with ceftriaxone and metronidazole with no evidence of mediastinal infection and with aneurysm exclusion in the CT follow-up. CONCLUSION: The recognized biomechanical and anatomical complexity of the aneurysmatic thoracic aorta represents a considerable challenge to the endovascular treatment of aorto-esophageal fistulas, especially in aneurysmatic sealing of the aortic arch, with significant rates of type Ia and III endoleaks.

Pediatrician's knowledge on the management of the infant who cries excessively in the first months of life / Actitud, práctica y conocimiento del pediatra sobre el lactante que llora excesivamente durante los primeros meses de vida / Conhecimentos do pediatra sobre o manejo do lactente que chora excessivamente nos primeiros meses de vida

To evaluate the attitude, the practice and the knowledge of pediatricians regarding the management of the infant who cries excessively in the first months of life. METHODS: Descriptive cross-sectional study that enrolled pediatricians (n=132) randomly interviewed at a Pediatric meeting in Brazil, in August 2012. The data were collected by a self-administered standardized form after reading the hypothetical case of an infant who cried excessively. RESULTS: The majority of the participants were females, the mean age was 39 years and the average mean time working in the specialty was 14 years; 52.2% were Board Certified by the Brazilian Society of Pediatrics. The diagnosis most often considered was gastroesophageal reflux disease (62.9%), followed by infant colic (23.5%) and cow's milk allergy (6.8%). The diagnostic test most frequently mentioned was 24-hour esophageal pH-monitoring (21.9%).

Gastroesophageal reflux disease: exaggerations, evidence and clinical practice / Doença do refluxo gastroesofágico: exageros, evidências e a prática clínica

OBJECTIVE: there are many questions and little evidence regarding the diagnosis and treatment of gastroesophageal reflux disease (GERD) in children. The association between GERD and cow's milk protein allergy (CMPA), overuse of abdominal ultrasonography for the diagnosis of GERD, and excessive pharmacological treatment, especially proton-pump inhibitors (PPIs) are some aspects that need clarification. This review aimed to establish the current scientific evidence for the diagnosis and treatment of GERD in children. DATA SOURCE: a search was conducted in the MEDLINE, PubMed, LILACS, SciELO, and Cochrane Library electronic databases, using the following keywords: gastroesophageal reflux; gastroesophageal reflux disease; proton-pump inhibitors; and prokinetics; in different age groups of the pediatric age range; up to May of 2013. DATA SYNTHESIS: abdominal ultrasonography should not be recommended to investigate gastroesophageal reflux (GER). Simultaneous treatment of GERD and CMPA often results in unnecessary use of medication or elimination diet. There is insufficient evidence for the prescription of prokinetics to all patients with GER/GERD. There is little evidence to support acid suppression in the first year of life, to treat nonspecific symptoms suggestive of GERD. Conservative treatment has many benefits and with low cost and no side-effects. CONCLUSIONS: there have been few randomized controlled trials that assessed the management of GERD in children and no examination can be considered the gold standard for GERD diagnosis. For these reasons, there are exaggerations in the diagnosis and treatment of this disease, which need to be corrected. .

OBJETIVO: há muitas dúvidas e poucas evidências para o diagnóstico e tratamento da doença do refluxo gastroesofágico (DRGE) na criança. A relação entre a DRGE e a alergia às proteínas do leite de vaca (APLV), o uso exagerado da ultrassonografia abdominal para diagnóstico da DRGE e o excesso de medicamentos, especialmente dos inibidores de bomba de prótons (IBP), são alguns aspectos que necessitam esclarecimentos. Esta revisão tem como objetivo estabelecer as evidências científicas atuais para o diagnóstico e tratamento da DRGE em pediatria. FONTES DOS DADOS: foram pesquisadas nas bases de dados eletrônicos do Medline, Pubmed, Lilacs, Cochrane Library e Scielo, nas diferentes faixas etárias da pediatria, até maio de 2013, as seguintes palavras-chave: refluxo gastroesofágico, doença do refluxo gastroesofágico, inibidores da bomba de prótons e procinéticos. SíNTESE DOS DADOS: a ultrassonografia de abdome não deve ser recomendada para pesquisa de refluxo gastroesofágico (RGE). O tratamento simultâneo da DRGE e da APLV induz, muitas vezes, ao uso desnecessário de medicação ou dieta de exclusão. Não existem evidências suficientes para prescrição de procinéticos em todos os portadores de RGE/DRGE. Poucas evidências fornecem suporte para a supressão ácida, no primeiro ano de vida, para tratamento de sintomas inespecíficos, sugestivos de DRGE. O tratamento conservador traz muitos benefícios e poucos gastos, sem efeitos colaterais. CONCLUSÕES: existem poucos estudos controlados e randomizados que avaliam a DRGE na criança e nenhum exame pode considerado padrão-ouro para o seu diagnóstico. Por esses motivos, ocorrem exageros no diagnóstico e no tratamento dessa doença, e que necessitam ...
