Superior bioavailability of the calcium salt form of β-hydroxy-β-methylbutyrate compared with the free acid form.

We investigated the bioavailability of the calcium salt (HMB-Ca) and the free acid (HMB-FA) forms of β-hydroxy-β-methylbutyrate (HMB). Sixteen young individuals received the following treatments on three different occasions in a counterbalanced crossover fashion: (1) HMB-FA in clear capsules; (2) HMB-Ca in gelatine capsules; (3) HMB-Ca dissolved in water. All treatments provided 1 g of HMB.

Extracorporeal Pedicles for Free Flap Reconstruction in Diabetic Lower Extremity Wounds.

Diabetic foot ulcers are a severe complication of diabetes, and their management requires a multidisciplinary approach for optimal management. When treating these ulcers, limb salvage remains the ultimate goal. In this article, we present the "hanging" free flap for the reconstruction of chronic lower extremity diabetic ulcers.

The First Dorsal Metacarpal Artery Perforator Free Flap: The Comet Flap.

Background: Distal extremity defects pose a particular challenge to the reconstructive surgeon; however, advances in perforator flaps have expanded the potential reconstructive options. In this article, the authors present their experience in reconstructing distal extremity defects using a thin, cutaneous free flap based on the perforator of the first dorsal metacarpal artery: the comet flap.

Methods: A retrospective review was performed on all patients who presented with a distal extremity defect and underwent reconstruction using a comet flap between 2015 and 2019.

Pleomorphic adenoma of buccal mucosa: a case report and review of the literature.

Background: Salivary gland neoplasms are rare, accounting for 3% to 5% of all head and neck tumors, and involvement of the minor salivary glands is uncommon. Pleomorphic adenoma (PA) is the most common benign neoplasm, which mainly affects the parotid gland. However, involvement of the cheek mucosa is very rare.
