ABSTRACT Research on the genetics, epidemiology, and clinical manifestations of Fabry disease (FD) has increased significantly in recent years. However, some relevant clinical questions still need to be answered to develop better approaches to patient management. This review focuses on answering specific questions raised by Brazilian experts based on their experience in diagnosing and managing patients with FD. The questions are as follows: What is the role of globotriaosylsphingosine in diagnosis? How does one proceed with the diagnosis if there is a variant of unknown significance? What are the earliest and most reliable markers of renal, cardiac, and neurological impairment? What is the prevalence of FD in patients with cryptogenic stroke? What is the average delay in diagnosis in patients with FD? Based on these questions, our objective was to highlight epidemiological, diagnostic, and clinical aspects relating to the literature in the FD field.

Os autores relatam dois casos de fístula gastrocólica causada por uso crônico de indometacina em pacientes com síndrome de Bartter, em acompanhamento no Instituto da Criança do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo. O diagnóstico foi realizado por meio de trânsito intestinal, que evidenciou passagem de contraste da grande curvatura gástrica para o cólon transverso. O tratamento foi cirúrgico em ambos os casos.

The authors report two cases of gastrocolic fistula caused by chronic therapy with indometacin in patients with Bartter's syndrome followed at the outpatients clinic of "Instituto da Criança do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo", Brazil. The diagnosis was suggested by a barium meal that showed a gastrocolic fistula between the greater curvature of the stomach and the transverse colon. Treatment was surgical in the both cases.
