BACKGROUND Estrogen has been reported to accelerate cutaneous wound healing. This research studies the effect of young coconut juice (YCJ), presumably containing estrogen-like substances, on cutaneous wound healing in ovairectomized rats. METHODS Four groups of female rats (6 in each group) were included in this study. These included sham-operated, ovariectomized (ovx), ovx receiving estradio...

BACKGROUND Cutaneous wound healing is a complex process involving several signaling pathways such as the Wnt and extracellular signal-regulated kinase (ERK) signaling pathways. Valproic acid (VPA) is a commonly used antiepileptic drug that acts on these signaling pathways; however, the effect of VPA on cutaneous wound healing is unknown. METHODS AND FINDINGS We created full-thickness wounds o...

In contrast to adult cutaneous wound repair, early gestational fetal cutaneous wounds heal by a process of regeneration, resulting in little or no scarring. Previous studies indicate that down-regulation of HoxB13, a member of the highly conserved family of Hox transcription factors, occurs during fetal scarless wound healing. No down-regulation was noted in adult wounds. Here, we evaluate heal...

OBJECTIVE To quantify the oral cutaneous fistulae after surgery and to identify possible risk factors. METHODS A retrospective study, interesting patients that were submitted to surgery, with a two years minimum post-operative follow up. The considered variables were: sex, concomitant diseases, tabacco and alcohol use, the anesthesic and pulmonary risks, clinical stage, cervical linphadenecto...

Sino-orbital cutaneous fistulas are a well-documented complication of orbital exenteration and sinonasal carcinoma resection. Challenges to successful closure of this common complication include complex anatomy, communication with sinonasal mucosa, persistent mucopurulent drainage, compromised wound healing due to previous irradiation, and wound infection. We describe a novel approach for closu...

Physiological events in the initial inflammatory stage of cutaneous wound healing influence subsequent stages. Proinflammatory cytokines coordinate molecular and cellular processes during the inflammatory stage. Polyunsaturated fatty acids (PUFA) alter proinflammatory cytokine production, but how this phenomenon specifically influences wound healing is not clearly understood. In the present stu...

  Background: Wound complications following open repair for acute Achilles tendon ruptures (AATR) remain the subject of significant debate. The aim of this study is to investigate the effects of covering repaired AATR using well-nourished connective tissues (paratenon and deep fascia) to avoid complications after open repair.   Methods: In this case series study, open repair was performed for 3...

Integrins have been shown to play important roles in embryonic development, wound healing, metastasis, and other biological processes. alphavbeta5 is a receptor for RGD-containing extracellular matrix proteins that has been suggested to be important in cutaneous wound healing and adenovirus infection. To examine the in vivo function of this receptor, we have generated mice lacking beta5 express...
