Abstract

OBJECTIVE: To verify if the frequency of spontaneous pubertal development among girls with Turner syndrome (TS) diagnosed in infancy and childhood is greater than that of patients diagnosed later. SUBJECTS AND METHODS: Thirty three girls aged < 10 years at the time of diagnosis were evaluated regarding pubertal development. The frequency of spontaneous puberty was compared with that of girls aged > 13 years diagnosed at the same service. RESULTS: Sixteen of 32 informative patients had signs of spontaneous puberty, a frequency greater than that of patients diagnosed later. In six patients, there was no progression of puberty; menarche occurred in six, and one became pregnant, but the fetus was a stillborn. Spontaneous puberty was absent in all cases with 45,X karyotype. CONCLUSIONS: The greater prevalence of spontaneous puberty in girls whose diagnosis was not based on pubertal delay suggests that, among those diagnosed later, there is a bias towards patients with hypogonadism.

SUJEITOS E MÉTODOS: Foram avaliadas 33 meninas < 10 anos ao diagnóstico quanto ao desenvolvimento puberal. A frequência de puberdade espontânea foi comparada com a de pacientes com mais de 13 anos diagnosticadas no mesmo serviço. RESULTADOS: Dezesseis das 32 pacientes informativas tiveram sinais puberais espontâneos, frequência superior a daquelas diagnosticadas posteriormente. Em seis delas, não houve progressão da puberdade; a menarca ocorreu em seis casos e uma paciente ficou grávida, porém o feto foi natimorto. Em todos os casos com cariótipo 45,X não ocorreu puberdade espontânea. CONCLUSÕES: A maior prevalência de puberdade espontânea em meninas cujo diagnóstico não se baseou em atraso puberal sugere que naquelas detectadas posteriormente haja distorção em favor de pacientes com hipogonadismo.
