Osteoporotic fractures impose severe physical, psychosocial, and financial burden both to the patient and the society. Studies on the prevalence of osteoporosis and fragility fractures in Brazil show a wide variation, due to differences in sample size, the population studied, and methodologies. Few studies have been conducted in Brazil about the cost-effectiveness analyses of different intervention options aimed at the diagnosis and treatment of osteoporosis. Investigation and treatment strategies based on cost-effectiveness and scientific evidence are essential in the preparation of public health policies with the ultimate goal of reducing the incidence of fractures and, consequently, the direct and indirect costs associated with them. This article reviews the Brazilian burden of osteoporosis in terms of the prevalence and fractures attributable to the disease, the costs related to the investigation and management, as well as the impact of osteoporosis on the population as a whole and on affected individuals.

Estudos sobre a prevalência de osteoporose e fraturas por fragilidade no Brasil mostram uma grande variação, em decorrência das diferenças no tamanho das amostras, da população estudada e da metodologia empregada. Poucos estudos têm sido realizados no Brasil sobre a análise de custo-efetividade das diferentes opções de intervenção que visam ao diagnóstico e ao tratamento da osteoporose. Estratégias de investigação e de tratamento com base na relação custo-eficácia e evidências científicas são essenciais para a elaboração de políticas de saúde pública, com o objetivo final de reduzir a incidência de fraturas e, consequentemente, os custos diretos e indiretos associados a elas. Este artigo faz uma revisão sobre o ônus da osteoporose no Brasil em termos de prevalência e fraturas atribuí-veis à doença, de custos relacionados com a investigação, tratamento da osteoporose, bem como seu impacto na população como um todo e em indivíduos afetados.

Introduction Recurrent tracheoesophageal fistula (TEF) is a challenging complication in children with repaired esophageal atresia (EA). Thoracotomy, with surgical repair, is the traditional therapeutic approach, however it is often associated with a significant morbidity and technical difficulty. Endoscopic techniques, from the tracheal and/or esophageal side, have recently been proposed as a primary treatment, in order to prevent reoperation especially in previously operated fields. Aim of this retrospective study is to present our experience as Tertiary Care Center and Referral Center for EA, on the endoscopic management of recurrent TEF in children with repaired EA. Method This is a retrospective study conducted on children with repaired EA referred at Bambino Gesù Children's Hospital from January 2009 to January 2019. Demographic and clinical details, including type of EA, presence of fistula, concomitant malformations, endoscopic evaluation, number and kind of treatments, performed were collected. Results We identified 171 patients with EA, 15 type 1 (9%), 7 type 2 (4%), 140 type 3 (82%), 6 type 4 (3%), 3 type 5 (2%). Among patients with TEF, 11/156 (7%- M:F/6:5) presented with a TEF recurrence. Among the latter, 5 (45.4%) were patients with concomitant malformation (2 VACTER, 2 anorectal malformation, 1 Down syndrome, cardiac abnormalities, and hypothyroidism). All patients with TEF recurrence presented with symptoms, such as chronic cough, vomit, bronchitis, recurrent pneumonia, and failure to thrive. All patients underwent endoscopic evaluation both from digestive and tracheal side. Six (6/11–54.5%) patients underwent surgery, 5 patients (5/11–45.4%) were treated with endoscopic transtracheal fibrin glue injection after brushing that was successful in two patients (2/5–40%), one patient needed a retreatment. These patients maintained successful closure after treatment confirmed at endoscopic follow-up. Remaining three patients needed surgical approach during follow-up. Conclusion Endoscopic repair of recurrent TEF has proved safe and effective in the literature as an alternative to a second open thoracotomy/surgical repair. In our series, although in two cases, it represented a valid alternative to surgery. We suggest that it is worthy to try a conservative approach before surgery.
