Pregnancy has no significant impact on the prognosis of differentiated thyroid cancer

ABSTRACT Objective: To evaluate the impact of pregnancy on differentiated thyroid carcinomas (DTC) behavior Subjects and methods: Retrospective study of patients diagnosed with DTC before or during pregnancy and treated with standard therapy. In women diagnosed with DTC before pregnancy, we evaluated the occurrence of progression according to categories of response to therapy based on imaging and non-stimulated thyroglobulin (TG) levels. Results: Of 96 analyzed patients, 76 became pregnant after DTC treatment and 20 were diagnosed with DTC during pregnancy. Among women who became pregnant after a DTC diagnosis, no difference was observed regarding response to therapy before and after pregnancy. Disease progression after pregnancy was documented in six of these patients, while seven of them presented progression before pregnancy but were only treated after delivery. Patients with DTC diagnosed during pregnancy had a higher rate of distant metastases at diagnosis (30%) compared with the patients who became pregnant after DTC diagnosis (9.2%, p = 0.01). Conclusion: Pregnancy had no impact on the natural course of DTC. Disease progression after pregnancy was limited and probably related to more aggressive disease and higher risk stratification at diagnosis. Still, mild disease progression may have occurred asymptomatically in some patients.

Hiperplasia adrenal congênita / Congenital adrenal hyperplasia

A hiperplasia adrenal congênita (HAC) é um grupo de doenças de transmissão autossômica recessiva, em que os defeitos enzimáticos levam à síntese deficiente do cortisol e excesso de androgênios adrenais. A deficiência da 21?-hidroxilase é a forma mais frequente. Na HAC clássica o excesso de androgênios resulta em virilização e desenvolvimento de genitália ambígua no recém-nascido do sexo feminino e, quando não diagnosticada, alta mortalidade no sexo masculino. É necessário um diagnóstico preciso e urgência no início do tratamento para prevenir a mortalidade e as morbidades que acompanham esta doença. Os autores apresentam de forma prática e concisa como diagnosticar, tratar e prevenir complicações.
