Severe menorrhagia, unilateral ovarian mass, elevated inhibin levels, and severe hypothyroidism: an unusual presentation of Van Wyk and Grumbach syndrome.

A 10 year old female presented with a 3 week history of persistent vaginal bleeding, lower abdominal pain, and generalized fatigue. Further work-up determined that she had severe autoimmune hypothyroidism, precocious puberty, and a large left cystic ovarian mass, consistent with Van Wyk and Grumbach syndrome. In addition, the patient had elevated inhibin A and B levels, which may be elevated in granulosa cell tumor. The patient was managed with thyroid hormone replacement therapy and careful observation. Complete resolution of the ovarian mass and interval normalization of the inhibin levels were achieved. In females with severe primary hypothyroidism, ovarian masses, and elevated tumor markers, operative resection may be avoided with appropriate thyroid replacement therapy and close observation.

Successful prolonged use of recombinant human insulin-like growth factor-1 in a child with cystic fibrosis.

Growth failure is a common and complicated process in children with cystic fibrosis (CF). Growth hormone, which is becoming a more commonly used agent in such patients, has demonstrated beneficial effects aside from increased growth velocity. Recently, insulin-like growth factor-1 has gained significant attention in the understanding of growth failure in children with CF. We report the successful prolonged use of recombinant human insulin-like growth factor-1 in an adolescent boy with CF, who demonstrated significant clinical benefits from the therapy.
