We report struma ovarii in a case that had hyperthyroidism and was treated with laparoscopic tumor resection. A 40-year-old Japanese woman presented with tachycardia, finger tremor, and weight loss. Although blood examination showed hyperthyroidism, test results for thyroid stimulating hormone receptor antibody and thyroid stimulating antibody were negative, and thyroid scintigraphy showed no abnormal findings. Because she was diagnosed with an ovarian tumor, and whole-body scintigraphy showed that iodine uptake was detected in the pelvic space, we diagnosed her with an ovarian tumor, which caused excessive thyroid hormone secretion. After controlling the thyroid hormone level, we resected the ovarian tumor laparoscopically. The thyroid hormone level was within the normal range postoperatively without any medications. Based on our experience, physicians need to remember that ovarian tumors can cause hyperthyroidism. Controlling the thyroid hormone level preoperatively by using antithyroid drugs and performing minimally invasive laparoscopic surgery is considered useful for preventing thyroid storm.

Repeat-associated non-AUG (RAN) translation is a noncanonical translation initiation event that occurs at nucleotide-repeat expansion mutations that are associated with several neurodegenerative diseases, including fragile X-associated tremor ataxia syndrome (FXTAS), ALS, and frontotemporal dementia (FTD). Translation of expanded repeats produces toxic proteins that accumulate in human brains and contribute to disease pathogenesis. Consequently, RAN translation constitutes a potentially important therapeutic target for managing multiple neurodegenerative disorders. Here, we adapted a previously developed RAN translation assay to a high-throughput format to screen 3,253 bioactive compounds for inhibition of RAN translation of expanded CGG repeats associated with FXTAS. We identified five diverse small molecules that dose-dependently inhibited CGG RAN translation, while relatively sparing canonical translation. All five compounds also inhibited RAN translation of expanded GGGGCC repeats associated with ALS and FTD. Using CD and native gel analyses, we found evidence that three of these compounds, BIX01294, CP-31398, and propidium iodide, bind directly to the repeat RNAs. These findings provide proof-of-principle supporting the development of selective small-molecule RAN translation inhibitors that act across multiple disease-causing repeats.
