BACKGROUND: The use of surgical drains has been considered mandatory after pancreatic surgery. The role of prophylactic abdominal drainage to reduce postoperative complications after pancreatic surgery is controversial. OBJECTIVES: To assess the benefits and harms of routine abdominal drainage after pancreatic surgery, compare the effects of different types of surgical drains, and evaluate the optimal time for drain removal. SEARCH METHODS: For the initial version of this review, we searched the Cochrane Library (2015, Issue 3), MEDLINE (1946 to 9 April 2015), Embase (1980 to 9 April 2015), Science Citation Index Expanded (1900 to 9 April 2015), and Chinese Biomedical Literature Database (CBM) (1978 to 9 April 2015)...

Chronic wounds are a common and debilitating complication for the diabetic population. It is challenging to study the development of chronic wounds in hu-man patients; by the time it is clear that a wound is chronic, the early phases of wound healing have passed and can no longer be studied. Because of this limita-tion, mouse models have been employed to better understand the early phases of chronic wound formation. In the past few years, a series of reports have high-lighted the importance of reactive oxygen species and bacterial biofilms in the development of chronic wounds in diabetics...

INTRODUCTION: Impaired wound healing has been widely reported in diabetes. Linoleic acid (LA) accelerates the skin wound healing process in non-diabetic rats. However, LA has not been tested in diabetic animals. OBJECTIVES: We investigated whether oral administration of pure LA improves wound healing in streptozotocin-induced diabetic rats. METHODS: Dorsal wounds were induced in streptozotocin-induced type-1 diabetic rats treated or not with LA (0...

Glycerol monolaurate (GML) is a monoglyceride with well characterized anti-microbial properties. Because of these properties, GML is widely used in food, cosmetics, and personal care products and currently being tested as a therapeutic for menstrual associated toxic shock syndrome, superficial wound infections, and HIV transmission. Recently, we have described that GML potently suppresses select T cell receptor (TCR)-induced signaling events, leading to reduced human T cell effector functions. However, how soluble host factors present in the blood and at sites of infection affect GML-mediated human T cell suppression is unknown...

One of the most impressive soft tissue injuries is the facial degloving, normally associated with industrial machines and traffic accidents. This injury is characterized by the separation of the skin and cartilage from the bones, compromising the soft tissues correlated in the trauma area, nerves, and blood vessels. A 28-year-old patient, male, was referred to Araçatuba's Santa Casa Hospital, after a motorcycle accident, hitting his face on the sidewalk. The patient was conscious, oriented, denying fainting and unconsciousness during the accident, and complaining of pain in the nasal region of the face...

Bilateral internal thoracic artery (BITA) grafting may be associated with a higher risk of postoperative deep sternal wound infection than monolateral internal thoracic artery grafting due to a limited blood supply to the thoracic chest wall. Because preliminary studies suggest negative pressure wound therapy (NPWT) may reduce the risk of infection, a retrospective chart review of 129 patients who underwent BITA between February 2003 and October 2014 was conducted. Of those, 21 patients received NPWT for 5 days immediately following surgery and the incisions of 108 patients were covered with a conventional gauze dressing...

Skinning injury on potato tubers is a kind of superficial wound that is generally inflicted by mechanical forces during harvest and postharvest handling operations. Though skinning injury is pervasive and obstructive, its detection is very limited. This study attempted to identify injured skin using two CCD (Charge Coupled Device) sensor-based machine vision technologies, i.e., visible imaging and biospeckle imaging. The identification of skinning injury was realized via exploiting features extracted from varied ROIs (Region of Interests)...

BACKGROUND: Polydeoxyribonucleotide (PDRN) is an active compound that can promote wound healing. PDRN stimulates wound healing by enhancing angiogenesis and increasing fibroblast growth rates. Laser skin resurfacing is a popular cosmetic procedure for skin rejuvenation. Despite excellent improvement of photo-damaged skin and acne scarring, it is accompanied with drawbacks, such as prolonged erythema and crusting. OBJECTIVE: This study was designed to assess the effect of PDRN on wounds induced by fractional laser resurfacing...

Acne vulgaris treatments usually cause sensitivity, teratogenicity and bacterial resistance. Investigations of others therapeutic techniques, such as phototherapy, is highly relevant. Thus, we compared the effectiveness of two Acne vulgaris treatments in adolescents: peeling with salicylic acid and phototherapy. Teens were randomly divided in: group I, treatment with salicylic acid peels (10 %) and group II, treatment with phototherapy (blue LED and red laser lights). Photographs were taken before and after ten sessions of each treatment, carried out weekly, and compared...

Background Lateral malleolar fractures (Weber type B or OTA 44-B) account for 60% of all ankle fractures. To achieve anatomic restoration, surgical stabilization provides better results than conservative treatment. Various fixation methods are available to treat these fractures; however, the best method is still unknown. Our objectives were to present a new, useful, and efficient surgical technique for stabilizing lateral malleolar fractures and to analyze the outcomes of patients treated with the compression cerclage system...

Substitution urethroplasty for the treatment of male stricture disease is often accompanied by subsequent tissue fibrosis and secondary stricture formation. Patients with pre-existing morbidities are often at increased risk of urethral stricture recurrence brought upon in-part by delayed vascularization accompanied by overactive inflammatory responses following surgery. Within the context of this study, we demonstrate the functional utility of a cell/scaffold composite graft comprised of human bone marrow-derived mesenchymal stem cells (MSC) combined with CD34+ hematopoietic stem/progenitor cells (HSPC) to modulate inflammation and wound healing in a rodent model of substitution urethroplasty...

With the aim of up-regulating antitumor efficacy and down-regulating adverse effects, the amino group in the 3-positon of amonafide aromatic ring was modified by coupling with different amine/polyamine motifs via two linkers. Two series of naphthalimide derivatives were designed and synthesized and evaluated for their antitumor properties in vitro and in vivo. The preliminary in vitro trials revealed that compounds with urea as the linker were not active, and the presence of aspirin elevated the potency of 6k against tumor cells, wound healing and the protein expression of Cyclic D1 and MMP9...

For normal embryonic development/morphogenesis, cell migration and homing are well-orchestrated and important events requiring specific cellular mechanisms. In diseases such as cancer deregulated cell migration represents a major problem. Therefore, numerous efforts are under way to understand the molecular mechanisms of tumor cell migration and to generate more efficient tumor therapies. Cell migration assays are one of the most commonly used functional assays. The wound-healing assay or the Boyden chamber assay are variations of these assays...

PURPOSE: Laparoscopic surgery (LS) has proved superior compared to conventional surgery (CS) regarding morbidity, length of hospital stay, rate of wound infection and time until recovery. An improved preservation of the postoperative immune function is assumed to contribute to these benefits though the role of the local peritoneal immune response is still poorly understood. Our study investigates the peritoneal immune response subsequent to abdominal surgery and compares it between laparoscopic and conventional surgery to find an immunological explanation for the clinically proven benefits of LS...

Diabetes mellitus (DM) is considered one of the major chronic diseases in the world. Long-term hyperglycemia considerably affects the body tissues, and consequently, can lead to morbidity and mortality. Moreover, many oral complications have been observed with DM but little consideration in relation to the placement of dental implants has been investigated. Dental research has analyzed the relation of dental implants and bone osseointegration in diabetic patients. Theoretically, an impaired immune system and delayed wound healing of these patients might decrease the success rate of implant placement; however, with noticeable advances in evidence-based dentistry and statistically significant results, successful implant treatment could be achieved significantly in well-controlled diabetic patients...
