Do insulin resistance and hyperandrogenism have no substantive association with birth weight in adolescents with polycystic ovary syndrome?
Low birth weight may influence the appearance of hyperandrogenism and insulin resistance in a portion of adolescents with PCOS, but only 9% of the adolescents with PCOS in this study were SGA. In the majority of adolescents with PCOS, hyperinsulinemia and hyperandrogenism are related to factors other than birth weight alone.
Surgical resection of thymoma is the preferred treatment, because it is safe and effective with a low rate of recurrence and a good long-term survival. Advanced and invasive thymomas require a multimodal approach for better local tumor control and further improvement of prognosis.
