  "current_answer": "Lipedema was first described as a distinct syndrome by Allen and Hines at the Mayo Clinic in 1940, and consolidated in a large case series by Wold, Hines and Allen in 1951. On the surgical side, Ivo Pitanguy's 1964 paper on 'trochanteric lipodystrophy' is an early landmark in operating on the disproportionate gynoid fat that characterizes the condition — predating the development of liposuction (Fischer, 1970s; Illouz, 1980s). The modern, lipedema-specific surgical treatment is lymph-sparing tumescent liposuction, with single-centre cohorts reporting durable symptom relief at up to 12 years. These entries record how the field developed; they are historical landmarks, not head-to-head effectiveness comparisons.",
  "current_answer_pt": "O lipedema foi descrito pela primeira vez como síndrome distinta por Allen e Hines, na Mayo Clinic, em 1940, e consolidado em uma grande série de casos por Wold, Hines e Allen em 1951. No campo cirúrgico, o artigo de Ivo Pitanguy de 1964 sobre a 'lipodistrofia trocantérica' é um marco inicial na operação da gordura ginoide desproporcional que caracteriza a condição — anterior ao desenvolvimento da lipoaspiração (Fischer, anos 1970; Illouz, anos 1980). O tratamento cirúrgico moderno, específico para o lipedema, é a lipoaspiração tumescente poupadora de linfáticos, com coortes unicêntricas relatando alívio sintomático durável em até 12 anos. Estes registros documentam como o campo evoluiu; são marcos históricos, não comparações diretas de eficácia.",
  "major_uncertainty": "Historical 'firsts' are attributions, not settled facts: early reports predate modern lipedema criteria, and the boundary with adjacent fat-distribution disorders (e.g. trochanteric lipodystrophy) is blurred.",
