Lingual thyroid is a rare developmental disorder and is more frequent in women. The pathogenesis is unclear but may be related to the presence of maternal blocking autoantibodies against the thyroid. Treatment of this disorder includes the use of levothyroxine in order to correct the hypothyroidism, which is very frequent and to induce the shrinkage of the gland. When symptoms of obstruction or bleeding appear, ablative therapy by means of surgery or radioiodine is warranted. We report three cases and discuss the approach to diagnosis and a strategy for management.

It was observed that Phileurus valgus larvae are capable to emit stridulation and forced air sound when disturbed, being able to emit a “compound sound”. Duration, frequencies, oscillograms, spectrograms of the sounds obtained are presented. The results obtained are compared with previous studies and the possible communicative or warning functions they may have in their natural environment when interacting with other larvae (other species) or their congeners (same species). The audios obtained in the study are shared.
