OBJECTIVES The tension on a wound is one of the important factors that determine the degree of fibrosis and scar formation. We hypothesized that local botulinum toxin type A (Botox) induced paralysis of the musculature subjacent to a surgical wound with a skin defect would minimize the repetitive tensile forces on the surgical wound's edges, and this will result in a decreased fibroplastic resp...

background wound healing is a dynamic process with inflammatory response and oxidative reaction in the damaged area. alpha ointment (ao) and arnebia euchroma (arnebia) are herbal medicines with antioxidant and anti-inflammatory effects that can be used as wound healing agents. ao is a commonly used ointment while arnebia is a newly introduced one. objectives we aimed to compare the effects of a...

Wound healing is an intricate process that involves many types of cells, reaction pathways as well as chemical, physical and electrical cues. Since biochemical reactions and physiological events are pH-dependent we study here pH as an important major characteristic of the wound healing process in the presence of endogenous and exogenous electric fields. Our model gives the spatial pH distributi...

PURPOSE Abdominoperineal resection (APR) of advanced lower rectal cancer carries a high incidence of perineal wound infection. The aim of this study was to retrospectively evaluate risk factors for perineal wound infection after APR. METHODS The study group comprised 154 patients who underwent APR for advanced lower rectal cancer in our department from January 1990 through December 2012. The ...

BACKGROUND Extension of a single incision for the purpose of specimen extraction in single-port laparoscopic surgery (SPLS) can undermine the merits of SPLS, either by hurting cosmesis or by increasing wound morbidity. METHODS We retrospectively analyzed the clinical outcomes of patients undergoing SPLS sigmoidectomy, either with transanal specimen extraction (TASE, n = 15) or transumbilical ...

OBJECTIVE A randomized controlled trial to evaluate the effectiveness of a polyhexamethylene biguanide (PHMB) foam dressing compared with a similar non-antimicrobial foam for the treatment of superficial bacterial burden, wound-associated pain, and reduction in wound size. SETTING AND PARTICIPANTS This study was conducted in 2 wound healing clinics-a university hospital-based clinic and a com...

     Nitric oxide (NO) is an important molecule synthesized during wound repair. Studies have reported the use of NO donors on cutaneous wound repair, but their effects in different phases of healing are not elucidated. The aim of this work was to investigate the effects of topical sildenafil on wounds in rats. Sildenafil (25 mg) was topically applied once daily on wound in treatment groups. On...

In order to evaluate relationships between healing rates and initial wound area, epithelial wounds were made on rabbit corneas by scraping the epithelium within a 4-, 6.5-, or 8-mm trephine mark. The wounds were stained with fluorescein and photographed during healing. The wounded areas were measured by planimetry. Although larger wounds closed later than smaller wounds, all of the healing curv...

BACKGROUND The postoperative scaring, ostial stenosis, and adhesions after functional endoscopic sinus surgery for chronic rhinosinusitis remains a major problem. This study was designed to evaluate two new hyaluronan (HA) hydrogels for neo-ostium antistenosis and promoting wound healing in a rabbit maxillary sinus model. METHODS The anterior wall of the maxillary sinus of 48 rabbits was rem...
