Various biological dressings, for example, human fresh and cadaver skin grafts, homologous cultured human epithelium and deep frozen porcine split skin (Lyocutis), have been used to treat skin loss. Each of these biological dressings has its advantages and disadvantages. The antimicrobial properties of each dressing type are important since bactericidal activity influences the lifespan of the transplanted tissue. In the present study the in vitro antimicrobial effects of human fresh skin, homologous cultured epithelium and Lyocutis were compared to in vivo bactericidal activity of these dressings and possible clinical applications are recommended.

Division of Pulmonary and Critical Care Medicine, Albany Medical College, 16 New Scotland Avenue, MC-91, Albany, NY, 12208, USA.
Purpose: The priorities and concerns of sarcoidosis patients in the United States (US) have not been well-described.
Methods: A survey constructed by sarcoidosis patients and doctors was administered to US sarcoidosis patients. The survey queried patients concerning their demographics, disease state, disease impact on health and well-being, health care priorities and impressions of sarcoidosis care.
Evaluation of a transverse perineal approach to the canine vagina and vestibule.

There are a variety of surgical conditions impacting the canine vagina and vestibule that require access through a caudal approach. A standard vertical episiotomy involves making an incision beginning ventral to the anus and extending ventrally through the dorsal commissure of the vulva and into the lumen of the vestibule and distal vagina. The objective of this study was to determine if complex vaginal procedures could be performed via a transverse perineal approach, thus eliminating the need to incise and reconstruct the vulva as performed in a standard episiotomy, and to evaluate the feasibility of vaginal resection with vulvar-sparing vestibular urethrostomy using this transverse approach.

A Topical Formulation Containing Ferment for Managing Barrier Damage After Mild-Moderate Skin Disruption from Cosmetic Dermatologic Procedures.
J Clin Aesthet Dermatol
January 2025
Dr. Saliou is with The Estée Lauder Companies in Melville, New York.
Objective: The primary objective of these studies was to evaluate the potential of a serum containing Macrocystis pyrifera ferment (MPF-Serum) to both strengthen the barrier of intact skin and enhance barrier recovery after a non-ablative laser procedure or glycolic acid chemical peel.
Methods: Two whole-face clinical trials and three split-face, randomized, controlled clinical trials were conducted in women aged 31 to 65 years. The effect of MPF-Serum on barrier integrity and strength was assessed by transepidermal water loss measurement before and after controlled tape-stripping experiments and in-clinic 70% glycolic acid peel and non-ablative laser procedures.
