Variations of Extended Latissimus Dorsi Musculocutaneous Flap for Reconstruction of Large Wounds in the Extremity.

Objective: The aim of the present study was to report a novel nomenclature system for extended latissimus dorsi musculocutaneous (LD) flaps. To evaluate the clinical application and surgical efficacy of the different extended LD flaps for large wounds in the extremities.

Methods: From January 2004 to December 2018, 72 consecutive patients who received extended LD flaps were retrospectively analyzed.

Role of Zinc in Mucosal Health and Disease: A Review of Physiological, Biochemical, and Molecular Processes.

Zinc is an essential trace element of all highly proliferating cells in the human body. It is essential to the development and growth of all organisms. Zinc plays a critical role in modulating resistance to infectious agents and reduces the duration, severity, and risk of diarrheal disease via improved regeneration of intestinal epithelium, improved absorption of water and electrolytes, increased levels of brush border enzymes, and, possibly, an enhancement in the immune response allowing better clearance of pathogens.
