Acute wound infections management: the 'Don'ts' from a multidisciplinary expert panel.

Introduction: The management of acute wounds may be affected by malpractices leading to poor outcome, prolonged hospital stay and inappropriate use of antibiotic therapy.Areas covered: Acute wound infections are represented by surgical site and post-traumatic infections. The aim of this expert opinion is to identify a list of inadvisable actions and to provide a guide for an optimal management of acute wound infections. A literature search using Pubmed/MEDLINE database was performed. Articles pertaining to areas covered published until December 2019 were selected. We identified the most common malpractices in this setting and, using the Choosing Wisely methodology, we proposed a list of "Don'ts" for an easy use in clinical practice.Expert opinion: Malpractices may occur from the surgical prophylaxis to the discharge of patient. A prolonged surgical prophylaxis, the underestimation of signs and symptoms, the omission of source control, the inappropriate collection of wound swab, the improper use of clinical microbiology and pharmacology, the lack of hygiene measures and the delay of discharge are all factors that may lead to unfavorable outcome. A multidisciplinary approach is needed to optimally manage these patients. The "Don'ts" refer to all professional figures involved in the management of patients with acute wound infections.

Improving wound healing and preventing surgical site complications of closed surgical incisions: a possible role of Incisional Negative Pressure Wound Therapy. A systematic review of the literature.

Advances in preoperative care, surgical techniques and technologies have enabled surgeons to achieve primary closure in a high percentage of surgical procedures. However, often, underlying patient comorbidities in addition to surgical-related factors make the management of surgical wounds primary closure challenging because of the higher risk of developing complications. To date, extensive evidence exists, which demonstrate the benefits of negative pressure dressing in the treatment of open wounds; recently, Incisional Negative Pressure Wound Therapy (INPWT) technology as delivered by Prevena™ (KCI USA, Inc., San Antonio, TX) and Pico (Smith & Nephew Inc, Andover, MA) systems has been the focus of a new investigation on possible prophylactic measures to prevent complications via application immediately after surgery in high-risk, clean, closed surgical incisions. A systematic review was performed to evaluate INPWT's effect on surgical sites healing by primary intention. The primary outcomes of interest are an understanding of INPWT functioning and mechanisms of action, extrapolated from animal and biomedical engineering studies and incidence of complications (infection, dehiscence, seroma, hematoma, skin and fat necrosis, skin and fascial dehiscence or blistering) and other variables influenced by applying INPWT (re-operation and re-hospitalization rates, time to dry wound, cost saving) extrapolated from human studies. A search was conducted for published articles in various databases including PubMed, Google Scholar and Scopus Database from 2006 to March 2014. Supplemental searches were performed using reference lists and conference proceedings. Studies selection was based on predetermined inclusion and exclusion criteria and data extraction regarding study quality, model investigated, epidemiological and clinical characteristics and type of surgery, and the outcomes were applied to all the articles included. 1 biomedical engineering study, 2 animal studies, 15 human studies for a total of 6 randomized controlled trials, 5 prospective cohort studies, 7 retrospective analyses, were included. Human studies investigated the outcomes of 1042 incisions on 1003 patients. The literature shows a decrease in the incidence of infection, sero-haematoma formation and on the re-operation rates when using INPWT. Lower level of evidence was found on dehiscence, decreased in some studies, and was inconsistent to make a conclusion. Because of limited studies, it is difficult to make any assertions on the other variables, suggesting a requirement for further studies for proper recommendations on INPWT.

Profunda Femoris Artery Perforator Propeller Flap: A Valid Method to Cover Complicated Ischiatic Pressure Sores.

We report the case of a 50-year-old paraplegic man with a complicated grade III/IV ischiatic pressure sore treated with a propeller flap based on the first perforator of the profunda femoris artery. Our aim was to surgically reconstruct an ischiatic pressure sore in a patient with ankylosis using a fasciocutaneous perforator propeller flap obtained from the posterior region of the thigh. Our decision to perform a profunda femoris artery perforator propeller flap reconstruction was mainly due to the anatomical contiguity of the flap with the site of the lesion and the good quality of the skin harvested from the posterior region of the thigh. The use of the perforator fasciocutaneous flap represents a muscle-sparing technique, providing a better long-term result in surgical reconstruction. The choice of the 180-degree propeller flap was due to its ability to provide a good repair of the pressure ulcer and to pass over the ischiatic prominence in the patient in the forced decubitus position. The operatory course did not present any kind of complication. Using this reconstructive treatment, we have obtained complete coverage of the ischiatic pressure sore.

Chronic wounds cause morbidity due to local infections, sepsis, osteomyelitis, but also increase mortality in the most severe cases and in patients with multiple comorbidities. Their increasing prevalence, associated disabilities and relevant health costs make chronic wounds a real social disease. At a time in which we hear more and more about spending reviews and reduction of health care costs, the natural evolution of Medicine and Health Care is increasingly directed towards the achievement of high quality standards while at the same time, reducing costs. It is in this framework that a hub and spoke model was used for organizing Plastic Surgery services in Ancona (Italy). In order to ensure appropriate clinical and organizational management of services, the activities of reference centres need to be widely integrated, by functional interconnections with activities of peripheral hospitals and local centres. Through a careful analysis of the Regional Reference Center for non - healing wounds in Ancona, the authors make some considerations regarding appropriate diagnostic-therapeutic-healthcare pathways and the correct use of human, material and technological resources in the area of wound healing.

The enhanced healing of a high-risk, clean, sutured surgical incision by prophylactic negative pressure wound therapy as delivered by Prevena™ Customizable™: cosmetic and therapeutic results.

According to the literature, incisional closure complications may range from postoperative surgical site infections, representing 17-22% of health care-associated infections, surgical wound dehiscence and formation of haematomas or seromas, and can lead to delayed or impaired incision healing. These kinds of situations are more common when wounds are closed under tension or in specific patient morbidities. Obesity, in particular, is associated with an impaired blood flow to tissues, predisposing the patient to increased risk of wound complications by various mechanisms. Incisional complications can become relevant economic burdens for health care systems because of an increase in the average length of hospital stay and readmissions, and additional medical and surgical procedures. Thus, a preventive therapy may have a critical role in the management of healing. Negative pressure wound therapy (NPWT) technology as delivered by Prevena™ Customizable™ (Kinetic Concepts Inc., San Antonio, TX) has recently been the focus of a new investigation, as a prophylactic measure to prevent complications via immediate postoperative application in high-risk, clean, closed surgical incisions. The authors present a 62-year-old class II obese female, who underwent bilateral inguinal dermolipectomy. Prophylactic NPWT as delivered by Prevena™ was performed successfully over surgical incisions. Cosmetic and therapeutic results are shown.

From the "charretera" to the supraclavicular fascial island flap: revisitation and further evolution of a controversial flap.

Wide tissue defects located on the face and neck area often require distant flaps or free flaps to achieve a tension-free reconstruction together with an acceptable aesthetic result. The supraclavicular island flap surely represents a versatile and useful flap that can be used in case of large tissue losses. Because of its wide arc of rotation, which ensures a 180-degree mobilization anteriorly and posteriorly, the flap can reach distant sites when harvested as a pure island flap. The main vascular supply of the flap, the supraclavicular artery, a branch of the transverse cervical artery or, less frequently, of the suprascapular artery, though reliable, is not a very large vessel. In some particular cases, when too much tension or angles that are too tight are present, the vascular supply of the flap can be difficult and special care must be taken to avoid flap failure. To avoid this problem, the authors started harvesting the flap not as a pure island flap but with a fascial pedicle, thin and resistant, which ensures good reliability; also, when a higher tension rate is present, it avoids the risk of excessive traction or kinking of the vessels. Twenty-five consecutive patients with various defects located on the head, neck, and thorax area were treated in the past 2 years using the modified supraclavicular island flap. There was no flap loss or distant necrosis of the flap, and there was marginal skin deepithelialization in only two cases, which only required minor surgery. Postoperative morbidity was low, similar to the classic supraclavicular island flap, with primarily closed donor sites, except for one case, and tension-free scars. The authors show how the modified supraclavicular island flap is a reliable and safe flap that gives a good aesthetic result with low risk concerning the viability of the transferred skin. The technique, similar to supraclavicular island flap harvesting, is easy to perform and is attractive in patients at risk for poor or delayed healing such as smokers or patients with complex medical histories.

Local rh-VEGF administration enhances skin flap survival more than other types of rh-VEGF administration: a clinical, morphological and immunohistochemical study.

The aim of the present study was to evaluate experimentally whether administration of recombinant (rh) vascular endothelial growth factor (VEGF) can protect skin flaps from necrosis and to study the optimum mode of rh-VEGF administration. We used rats to study the effects of local or systemic administration of rh-VEGF on skin flap during surgery; we also tested preoperative systemic administration of rh-VEGF to assess whether it may prepare the tissue to respond to the hypoxic injury better than previously tested methods. The animals were 30 male Sprague-Dawley rats. Group I rats received multiple systemic injections of rh-VEGF in the tail artery prior to flap dissection. Group II rats were injected with rh-VEGF in the clamped left epigastric artery during flap dissection; in this group, the left flaps thus received rh-VEGF locally (via incubation for 10 min during hypoxia) and the right flaps systemically, after blood flow restoration. Group III received saline solution instead of VEGF in the same way as group II. Skin samples from the distal portion of the flaps were collected on day 7 for morphological and immunohistochemical analysis. The flaps exhibiting the least necrosis were those treated with local rh-VEGF, followed by those treated with systemic rh-VEGF. The flaps that received rh-VEGF locally showed a strong VEGF expression on keratinocytes and endothelial cells, the greatest amount of mature and newly formed vessels and strong survivin expression in endothelial cells. Local rh-VEGF administration should thus be considered as an effective therapeutic option to enhance the survival of a tissue at risk for perfusion.

Paraffin oil injection in the body: an obsolete and destructive procedure.

Injection of foreign materials, such as paraffin oil, is an old and obsolete procedure. The authors describe previous uses for this procedure that had been used since the 19th century and the treatment of patients affected by such a disease.
