Adenocarcinoma originating from a completely isolated duplication cyst of the mesentery in an adult.

Alimentary tract duplications are uncommon congenital abnormalities that usually have an anatomical connection with some part of the gastrointestinal tract and have a common blood supply with the adjacent segment of intestine. A completely isolated duplication cyst (CIDC) is a very rare type of gastrointestinal duplication that does not communicate with the normal bowel segment and possesses its own exclusive blood supply. Only 5 CIDC cases in adults have been reported in the English medical literature.

Bone mineral density and bone turnover markers in patients on long-term suppressive levothyroxine therapy for differentiated thyroid cancer.

Purpose: Current management for patients with differentiated thyroid cancer includes near total thyroidectomy and radioactive iodine therapy followed by administration of supraphysiological doses of levothyroxine (L-T4). Although hyperthyroidism is a well known risk factor for osteoporosis, the effects of L-T4 treatment on bone mineral density (BMD) in patients with thyroid cancer do not appear to be as significant as with endogenous hyperthyroidism. In this study, we evaluated the impact of long-term suppressive therapy with L-T4 on BMD and bone turn over markers in Korean female patients receiving L-T4 suppressive therapy.
