Levothyroxine dose following thyroidectomy is affected by more than just body weight.

Objectives/hypothesis: To determine the factors that affect levothyroxine (LT4) requirements following thyroidectomy.

Study Design: Retrospective study.

Methods: This study evaluated 246 participants who had undergone total thyroidectomy and were on a stable dose of LT4.

Biodegradable polylactide membranes for bone defect coverage: biocompatibility testing, radiological and histological evaluation in a sheep model.

Large bony defects often show a delayed healing and have an increasing risk of infection. Several materials are used for the coverage of large defects. These materials must be biocompatible, easy to use, and must have an appropriate stability to present a mechanical hindrance.
