Background: Recently, the infiltration of a subpopulation of cells represented by mononucleated cells extracted from peripheral blood [Peripheral Blood-Mononuclear Cells (PB-MNCs)] is becoming a useful technique for medical and surgical regenerative procedures. Due to the angiogenetic and regenerative properties of PB-MNCs, the infiltration of these cells is, in our opinion, a new option indicated in the treatment of pathologies characterized by tissue dystrophy, loss of vascularization, and non-healing wounds., Case Presentation: A 25-year-old active smoker patient was diagnosed with Rhabdomyosarcoma of the anterior tibial muscle of his left leg and treated with neoadjuvant chemo- and radiotherapy (RT). After the tumor excision, the patient developed wound dehiscence with bone exposure and a perilesional radiation-induced chronic dermatitis characterized by skin dyschromia and hair thinning along the treated area. The patient underwent surgical debridement and reconstruction with autologous skin grafts and dermal substitutes, with poor outcomes due to graft failure. The patient was subsequently treated with surgical debridement and coverage with a reverse sural fascia-cutaneous flap. After 13 days, wound dehiscence was observed, and reconstruction of the dehiscent areas was performed with a split-thickness autologous skin graft with no success. After wound debridement, a new split-thickness skin graft was performed, and a concentrate of autologous PB-MNCs was injected in the flap and perilesional skin. After 14 days, graft take was reached, and improvements in perilesional tissue tropism were noted. At 2 months follow-up, the patient appeared completely healed., Conclusions: In our opinion, the use of PB-MNCs to treat conditions characterized by tissue dystrophy, which require neoangiogenesis and cell regeneration, can be a useful and unconsidered technique that could be utilized to improve tissue tropism. Furthermore, prospective trials are necessary to validate our observations.

Adipose-derived mesenchymal stem cells (ASCs) represent a valid therapeutic option for clinical application in several diseases, due to their ability to repair damaged tissues and to mitigate the inflammatory/immune response. A better understanding of the underlying mechanisms regulating ASC biology might represent the chance to modulate their in vitro characteristics and differentiation potential for regenerative medicine purposes. Herein, we investigated the effects of the demethylating agent 5-azacytidine (5-aza) on proliferation, clonogenicity, migration, adipogenic differentiation and senescence of ASCs, to identify the molecular pathways involved. Through functional assays, we observed a detrimental effect of 5-aza on ASC self-renewal capacity and migration, accompanied by actin cytoskeleton reorganization, with decreased stress fibers. Conversely, 5-aza treatment enhanced ASC adipogenic differentiation, as assessed by lipid accumulation and expression of lineage-specific markers. We analyzed the involvement of the Akt/mTOR, MAPK and Wnt/β-catenin pathways in these processes. Our results indicated impairment of Akt and ERK phosphorylation, potentially explaining the reduced cell proliferation and migration. We observed a 5-aza-mediated inhibition of the Wnt signaling pathway, this potentially explaining the pro-adipogenic effect of the drug. Finally, 5-aza treatment significantly induced ASC senescence, through upregulation of the p53/p21 axis. Our data may have important translational implications, by helping in clarifying the potential risks and advantages of using epigenetic treatment to improve ASC characteristics for cell-based clinical approaches., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Ceccarelli, Gerini, Megiorni, Pontecorvi, Messina, Camero, Anastasiadou, Romano, Onesti, Napoli and Marchese.)

Aim: Dermal fillers have been progressively used for cosmetic procedures. Concurrently, the rates of filler complications have also increased. The aim of this study is to describe the clinical management and treatment we performed in patients with complications occurred after filler injection., Methods: From March 2000 to February 2020, 197 patients have been evaluated for complications due to filler injection. For each patient type of material, symptoms and signs were recorded. Ultrasound evaluation was used to obtain information about the type, amount and location of the injected material. Magnetic Resonance Imaging was performed in those patients who were candidate for surgery. Based on the clinical manifestations, we performed a targeted therapy., Results: The local and systemic medical therapy allowed us a complete remission of the clinical signs and symptoms in all patients presented with edema and erythema. We obtained optimal results with surgery, where a complete removal of the injected material was possible. In all the cases in which the complete removal of the infiltrated area could have led to functional impairments, we performed partial removal with poor outcomes., Conclusion: We observed complex clinical manifestations in the patients subjected to permanent fillers. An accurate knowledge upon the effects of the materials on tissues, a specific instrumental evaluation and a targeted therapy are crucial. We suggest the use of absorbable fillers. Patient should be subjected to filler implant in authorized structures by an expert specialist with experience in filler injection and with a thorough knowledge of the anatomical structures., Level of Evidence Iv: This journal requires that authors assign a level of evidence to each article.

Adipose-derived mesenchymal stem cells (ASCs) are promising therapeutic tools in regenerative medicine because they possess self-renewal, differentiation and immunomodulatory capacities. After isolation, ASCs are passaged multiple times in vitro passages to obtain a sufficient amount of cells for clinical applications. During this time-consuming procedure, ASCs become senescent and less proliferative, compromising their clinical efficacy. Here, we sought to investigate how in vitro passages impact ASC proliferation/senescence and expression of immune regulatory proteins. MicroRNAs are pivotal regulators of ASC physiology. Particularly, miR-200c is known to maintain pluripotency and targets the immune checkpoint Programmed death-ligand 1 (PD-L1). We therefore investigated its involvement in these critical characteristics of ASCs during in vitro passages. We found that when transiently expressed, miR-200c-3p promotes proliferation, maintains stemness, and contrasts senescence in late passaged ASCs. Additionally, this miRNA modulates PD-L1 and Indoleamine 2,3-Dioxygenase (IDO1) expression, thus most likely interfering with the immunoregulatory capacity of ASCs. Based on our results, we suggest that expression of miR-200c-3p may prime ASC towards a self-renewing phenotype by improving their in vitro expansion. Contrarily, its inhibition is associated with senescence, reduced proliferation and induction of immune regulators. Our data underline the potential use of miR-200c-3p as a switch for ASCs reprogramming and their clinical application., Competing Interests: The authors have declared that no competing interests exist.

Background: The use of conservative mastectomies has risen significantly during the last few years. The reconstructive choice of direct-to-implant reconstruction has become more practicable with modern mastectomy techniques. The initial trend in Italian centers was to use dual-plane hybrid reconstruction. However, a high level of complications has been registered. From 2015 onward, in our centers, a pre-pectoral approach has been adopted. The authors sought to describe the Italian trend to gradually discard the sub-pectoral technique with lower lateral pole coverage of the prosthesis using ADMs comparing it with the pre-pectoral approach with ADMs, without any muscle dissection, in terms of complication rates., Materials and Methods: A multicenter retrospective clinical study was performed from January 2010 to June 2018. The enrolled patients were divided into two groups: Cases with an ADM-only coverage pre-pectoral reconstruction made up the first group (Group 1). Those with the retro-pectoral muscular position + ADM implant coverage comprised the second one (Group 2). Complications such as seroma, hematoma, wound dehiscence, surgical site infection, reconstruction failure, animation deformity and capsular contracture were recorded., Results: We performed 716 direct-to-implant reconstructions: 509 were partially sub-pectoral and 207 were pre-pectoral. Minimum follow-up was 1 year. Incidence of complications was higher in dual-plane reconstructions. There were statistical significant differences in the rates of seroma and hematoma., Conclusion: Using the pre-pectoral approach, the authors have experienced favorable aesthetics and superior clinical and functional outcomes. Retro-pectoral muscular ADM implant coverage has to be considered only in specific complicated second-stage surgeries., Level of Evidence V: This journal requires that authors assign a level of evidence to each article.

Backgrounds: Recently a flood of new techniques and studies have been released for prepectoral reconstruction, following strict criteria for selection of patients undergoing skin or nipple sparing mastectomy. Nevertheless a big population of patients that would otherwise benefit from prepectoral techniques has been excluded so far., Patients and Methods: Between January 2016 and February 2017, patients undergoing skin reducing mastectomy (SRM) were enrolled at our Institution. We selected patients with large and ptotic (grade II-III) breasts undergoing SRM, followed by a new technique, which involves placement of the implant, wrapped by acellular dermal matrix, in a prepectoral pocket under a dermal flap. Data of all the surgeries were prospectively collected and contracture grade was assessed by Baker scale. Complication rate and cancer recurrence were reported and health related quality of life (HRQOL) measurement was recorded using BREAST-Q questionnaire. At early follow-up, postoperative pain was assessed through VAS scale., Results: 29 patients underwent SRM and 10 patients, meeting inclusions criteria, were enrolled, with a total of 13 operated breasts. Postoperative average pain was assessed as low as 4.1. The median follow-up was 2.6 (range 2.1-3.2) years. Post-operative complications occurred in 1 case of minimal wound dehiscence. No patient reported breast seroma or severe capsular contracture grade. Patient scored high level of satisfaction with breast, psychosocial well-being, sexual well-being, physical impact and overall satisfaction with outcome, at BREAST-Q questionnaire., Conclusions: In this study we present a modified prepectoral technique for patients undergoing SRM, reporting satisfactory outcomes. These results might support the rationale for expanding the population target of prepectoral reconstruction., Competing Interests: Declaration of Competing Interest None of the authors has any conflict of interest or financial interest in any of the products, devices, or drugs mentioned in this manuscript. The study followed the ethical standards of human experimentation, according to the Declaration of Helsinki., (Copyright © 2019. Published by Elsevier Ltd.)

The skin graft is a surgical technique commonly used in the reconstructive surgery of the limbs, in order to repair skin loss, as well as to repair the donor area of the flaps and cover the dermal substitutes after engraftment. The unavoidable side effect of this technique consists of unaesthetic scars. In order to achieve the healing of posttraumatic ulcers by means of tissue regeneration and to avoid excessive scarring, a new innovative technology based on the application of autologous micrografts, obtained by Rigenera technology, was reported. This technology was able to induce tissue repair by highly viable skin micrografts of 80 micron size achieved by a mechanical disaggregation method. The specific cell population of these micrografts includes progenitor cells, which in association with the fragment of the Extracellular Matrix (ECM) and growth factors derived by patients' own tissue initiate biological processes of regeneration enhancing the wound healing process. We have used this technique in 70 cases of traumatic wounds of the lower and upper limbs, characterized by extensive loss of skin substance and soft tissue. In all cases, we have applied the Rigenera protocol using skin micrografts, achieving in 69 cases the complete healing of wounds in a period between 35 and 84 days. For each patient, the reconstructive outcome was evaluated weekly to assess the efficacy of this technique and any arising complication. A visual analogue scale (VAS) was administered to assess the amount of pain felt after the micrografts' application, whereas we evaluated the scars according to the Vancouver scale and the wound prognosis according to Wound Bed Score. We have thus been able to demonstrate that Rigenera procedure is very effective in stimulating skin regeneration, while reducing the outcome scar., Competing Interests: None of the authors have conflict of interest., (Copyright © 2019 Michele Riccio et al.)

Recently prepectoral breast reconstruction (PBR) has showed acceptable outcomes in the short-term. There are few evidence on long-term results and variables which could influence surgical safety. So far, no specific guidelines or indications have been developed for prepectoral technique and heterogeneous inclusion criteria had been used in previous reports. This study revises a series of 397 patients. We conducted a retrospective comparative analysis of risk factors and outcomes between patients undergoing direct to-implant (DTI) and patients undergoing two-stages expander-assisted (TSE) PBR. Univariate binary logistic regression was performed to investigate the association between the incidence of postoperative and aesthetic complications and several variables. 521 breasts were included in the analysis, with an average follow-up of 38 months. 210 patients underwent DTI and 187 TSE PBR. No statistical differences were found between the two populations in term of the characteristics of patients, surgeries and outcomes. Binary logistic regression found no significant association in the TSE group. In the DTI group, a significant association was found between surgical complications and BMI and adjuvant radiotherapy. The association remained significant only for BMI, when investigated with the onset of aesthetic complications. Lower BMI and adjuvant radiotherapy are significantly associated to a higher risk of developing a surgical complication in DTI PBR. Patients at lowest BMI with DTI are prone to develop an aesthetic complication. According to this analysis, we suggest to carefully choose candidates for PBR and propose new selection criteria for subcutaneous techniques., (Copyright © 2019 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.

Objective: A wound is defined as chronic when it requires more than 6 weeks to heal. The link between chronic wounds and depression was first pointed out by House and Hughes in 1996 and later evaluated by other numerous studies. Several studies demonstrate that among chronic skin wounds causing chronical physical disease, the leg ulcers are the most frequently associated with depression. The aim of our study is to evaluate the prevalence of depression in patients with different types of chronic wounds., Patients and Methods: We enrolled a total of 33 patients with chronic wounds and 33 healthy controls matched by sex and age. Both patients and controls underwent a BDI II survey. We evaluated 33 patients, with a mean age of 71 years (range 25-87), and 33 controls, with a mean age of 73 years (range 31-88)., Results: The average score at the BDI II questionnaire was 14.5 and 8, respectively., Conclusions: The depression among patients with chronic wounds has a multifactorial origin that should be treated with a multidisciplinary approach. Since the improvement of the psycho-emotional state means better compliance of the patient, we can also expect a better result in terms of efficacy in chronic wound treatment.

Objective: Surgical site infection (SSI) produces considerable morbidity and increases health care costs. One of its causes is microbial adherence to the surgical sutures surface. A strategy to avoid microbial colonization is the use of antimicrobial-impregnated sutures. Recently absorbable sutures treated with chlorhexidine (CHX) have been developed. Our study purpose was to compare CHX-coated and uncoated suture in elective plastic surgery., Patients and Methods: We conducted a randomized, double-blind, single-centre controlled trial of 18 patients undergoing elective bilateral mammary surgery and 18 patients undergoing skin lesions removals. Patients were divided into 2 groups receiving antibacterial-coated (study group) and uncoated (controlled group) sutures for wound closure. Patients were evaluated for scar results and signs of SSIs were monitored over a period of 30 days (or 1 year in case of prosthetic surgery). Statistical comparison was performed using dependent t-tests for paired samples., Results: For patients undergoing mammary surgery, based on Vancouver Scale, there were no significant differences between the two groups. We noticed that in 8 patients the vertical scars belonging to the control group were larger than the contralateral 8 vertical sutures belonging to the study group. For patients undergoing skin surgery, surgical wounds treated with uncoated sutures were significantly more erythematous than the ones belonging to the study group (Media: 0,8333% vs. 1,5556%, respectively; standard deviation: 9,235 vs. 0,6157; 95%; p=0.0092)., Conclusions: No wounds infection was reported between the two groups. Based on our experience, we conclude that the use of CHX-coated sutures should be considered in case of inflamed lesions removal. Further studies are needed to validate our results.

More than 50% of breast cancer care occurs in elderly but women aged 65 and over generally have lower breast reconstruction (BR) rates. In medical literature, few papers focused on BR in elderly patients and usually the reported techniques are multisteps such as expander-implant reconstruction, local, and free flaps. We present a one-stage reconstruction technique employed in elderly patients: muscle-sparing immediate BR with subcutaneous implant and Braxon acellular dermal matrix. We prove the feasibility and safety of the technique and believe that this new procedure could represent a potential benefit in elderly BR., (© 2017 Wiley Periodicals, Inc.)

Adipogenesis is regulated by a complex network of molecules, including fibroblast growth factors. Keratinocyte growth factor (KGF) has been previously reported to promote proliferation on rat preadipocytes, although the expression of its specific receptor, FGFR2-IIIb/KGFR, is not actually detected in mesenchymal cells. Here, we demonstrate that human adipose-derived stem cells (ASCs) show increased expression of KGF during adipogenic differentiation, especially in the early steps. Moreover, KGF is able to induce transient activation of ERK and p38 MAPK pathways in these cells. Furthermore, KGF promotes ASC differentiation and supports the activation of differentiation pathways, such as those of PI3K/Akt and the retinoblastoma protein (Rb). Notably, we observed only a low amount of FGFR2-IIIb in ASCs, which seems not to be responsible for KGF activity. Here, we demonstrate for the first time that Neuropilin 1 (NRP1), a transmembrane glycoprotein expressed in ASCs acting as a coreceptor for some growth factors, is responsible for KGF-dependent pathway activation in these cells. Our study contributes to clarify the molecular bases of human adipogenesis, demonstrating a role of KGF in the early steps of this process, and points out a role of NRP1 as a previously unknown mediator of KGF action in ASCs.

Tuberous breast deformity is a pathologic condition of the breast consisting of a constricting ring at the breast base, reduction in the volume of the breast parenchyma, and herniation of breast tissue through the nipple-areola complex with areola enlargement. This pathology is generally congenital and has an unknown etiopathogenesis. We report the first observation of tuberous breast deformity in consanguineous. This report suggests the potential role of a genetic base in the development of this deformity. Between May 2008 and March 2011, we observed six female patients from two different families, aged between 18 and 55 years, affected by tuberous breast deformity. The breast deformity was characterized by breast asymmetry in all six cases. Four patients underwent surgery to correct the deformity. Standardized objective measurements of breast and chest were taken. A Visual Analog Scale was used to evaluate patients' and physicians' satisfaction. The first three patients were consanguineous; two were first cousins, and the third was second cousin with one of the above. The other three patients were also from the same family: two sisters and their mother. According to Von Heimburg's classification, the patients presented different degrees of breast deformity. In all operated cases, a good esthetic result with a high satisfaction (average visual analog scale score 9) was achieved. The results remained stable over time and no revisions were needed after the 1-year follow-up. The possibility of a parental consanguinity for breast deformities such tuberous breast has never been described in the literature. This report suggests the possible genetic role in the development of tuberous breast deformity. Further studies and genetic tests are required to prove this hypothesis., (© 2017 Wiley Periodicals, Inc.)

Background: Prepectoral implant placement and complete coverage with porcine acellular matrix after mastectomy is a new concept in breast surgery presented in few cases in the literature. This paper aimed to present our single-center experience in one-stage breast reconstruction muscle-sparing "wrap" technique by evaluating clinical and aesthetic outcomes, ultrasound and histological examination, and patient quality of life., Methods: From January 2014 to January 2017, 52 patients (40 unilateral, 12 bilateral) underwent one-stage muscle-sparing breast reconstructions with Braxon ® acellular dermal matrix and implant. In 3 patients, a surgical biopsy and histological examination with immunohistochemical analysis of the periprosthetic tissue were performed. All patients underwent breast ultrasound examination, and the occurrence of capsular contracture was assessed through the Baker classification and by measuring the mammary compliance scores with the Antoon Paar Mammary compliance system. Breast appearance was evaluated using a visual analogue scale (VAS) and in terms of quality of life using the EOCRT QLQ C-30 and QLQ BR-23 questionnaires., Results: Early and late postoperative complications are reported. Histological and ultrasound evaluation showed a complete integration of the matrix. According to the VAS scale, the EOCRT QLQ C-30, and QLQ BR-23, patients' satisfaction resulted in a high score in terms of quality of life and aesthetic outcomes., Conclusion: The results of this new surgical technique in selected cases are promising in terms of effectiveness and low rate of postoperative complications, but further long-terms evaluations are required., (Copyright © 2017 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Chemotherapy extravasation may result in serious damage to patients, with irreversible local injures and disability. Evidence-based standardization on extravasation management is lacking and many institutions do not practice adequate procedures to prevent the severer damages. Our aim was to explore the prevention and treatment of extravasation injuries, proposing a standard therapeutic protocol together with a review of the literature. From January 1994 to December 2015, 545 cases were reviewed (age range, 5-87 years; 282 men and 263 women). Our therapeutic protocol consisted of local infiltration of saline solution and topical occlusive applications of corticosteroids. The infiltrations were administrated 3 to 6 times a week depending on damage severity. Our protocol allowed us to prevent ulceration in 373 cases. Only 27 patients required surgery (escarectomy, skin graft, regional, and free flap). Numerous treatments have been proposed in literature. The antidotes have been discussed controversially and are not considered standard methods for treatment, especially when polychemotherapy is administrated and the identification of the responsible drug is not possible. We proposed the use of saline solution injection to dilute rapidly the drug, thus reducing its local toxic effects. This method is easy to use and always reproducible even when the drug is not known or when it is administrated in combination with other drugs. It is possible to perform it in ambulatory regimen, and, overall, it represents a standard method.

Objective: The presence of ectopic or supernumerary breast tissue is a rare event, related to a not complete regression of breast tissue along the milk line. Primary ectopic breast cancer of the axilla can create many difficulties in differential diagnosis with subsequent delayed specific treatments. The incidence of ectopic breast tissue is 0.2-6%, and the axilla is the most common site involved. In this tissue, the same physiologic and pathologic changes as seen in ectopic breast tissue may occur, including carcinoma formation., Patients and Methods: Two patients (a 56 years old and 70 years old women) came to our attention for the recent development painless nodular axillary lesions, clinically characterized by an increased thickness, irregular margins and adherence to the floors below., Results: Patients underwent ultrasonography (US) and mammography (MMG) revealing non-specific features of the lesions. Magnetic resonance imaging (MRI), demonstrated margins slightly irregular and a non-specific appearance of each lesion. Both patients underwent wide local excision with axillary lymph node dissection. Histological examination showed infiltrating lobular carcinomas of the breasts., Conclusions: We describe two unusual cases of ectopic axillary breast carcinoma localization. It is important a correct and fast diagnosis with a local examination, diagnostic instruments, surgical excision and histological examination.

Extensive skin defect represents a real problem and major challenge in plastic and reconstructive surgery. On one hand, skin grafts offer a practical method to deal with skin defects despite their unsuitability for several complicated wounds. On the other hand, negative pressure wound therapy (NPWT), applied before skin grafting, promotes granulation tissue growth. The aim of the study is to evaluate the improvement in wound healing given by the merger of these two different approaches. We treated 23 patients for large wounds of multiple factors. Of these, 15 were treated with the application of V.A.C.® Therapy (KCI Medical S.r.l., Milan, Italy), in combination with skin grafts after a prior unsuccessful treatment of 4 weeks with mesh skin grafts and dressings. Another 8 were treated with only mesh skin graft. Pain reduction and wound area reduction were found statistically significant ( p < 0.0009, p < 0.0001). Infection was resolved in almost all patients. According to our study, the use of the negative pressure wound therapy over mesh skin grafts is significantly effective especially in wounds resistant to conventional therapies, thereby improving the rate of skin graft take., Competing Interests: None of the authors has any conflict of interests or financial interests in any of the products, devices, or drugs mentioned in this manuscript. None of the authors has any financial or personal relationships with other people or organizations that could inappropriately influence their work.

Objective: The aim of this study was to review one-stage breast reconstruction techniques performed in elderly patients at our institution to identify the criteria of selection of each in terms of outcomes and quality of life., Patients and Methods: Patients older than 65 years who underwent one-stage breast reconstruction between January 2004 and July 2014 at our hospital were included. Patients and procedure-related data were collected from the medical records. In particular, patient's age, comorbidities and related ASA physical status, type of one-stage breast reconstruction technique, and criteria of selection were analyzed. Outcomes and results were also evaluated in terms of quality of life using the EORTC QLQ-C30 and -BR23 questionnaires 1 year after surgery., Results: A total of 840 women underwent breast reconstruction, of whom 138 elderly women received one-stage breast reconstruction. There were 118 cases (85.5%) of monolateral reconstructions and 20 cases (14.5%) of bilateral reconstructions, resulting in 138 breast reconstructions. These were performed with permanent inflatable expanders in the sub-muscular position (Group A, n= 50), with acellular dermal matrix and partial sub-muscular anatomic implant (Group B, n= 50), and with Braxon® acellular dermal matrix and anatomic implant with muscle-sparing technique (Group C, n= 38). The EORTC questionnaires showed the best results in Group C regarding the quality of life., Conclusions: The elderly population is rapidly increasing, and 50% of all breast cancers occur in women older than 65 years; among them, only 2% undergo breast reconstruction. A major aspect of breast cancer treatment and subsequent quality of life is the opportunity for a post-mastectomy reconstructive surgery. As survival rates are improving, a larger proportion of patients live with the long-term consequences of their treatment, and breast reconstruction ensures a better quality of life. To increase the reconstruction rates, surgery should be one-stage, less invasive as possible, allowing rapid recovery, especially in elderly women, in whom comorbidities are often present with a higher anaesthetic risk. Our study highlighted that non-skin sparing mastectomy (SSM) and delayed reconstructions should be addressed with Becker implants; immediate reconstructions after SSM should be followed by acellular dermal matrix (ADM)-assisted implant reconstruction, preferring the wrap technique offers a better quality of life in elderly patients.

A chronic ulcer is usually defined as an injury that does not spontaneously evolve towards healing and does not progress through normal healing stages such as inflammation, proliferation and remodelling. This study was designed in order to compare two types of collagenases with mechanical debridement alone. It was thus possible to evaluate their differences in terms of pain and debridement efficacy. Patients were divided into three groups: 30 patients were daily dressed using an ointment based on collagenase produced by Vibrio alginolyticus (B group), 30 patients were daily dressed using an ointment based on a collagenase preparation derived from Clostridium histolyticum (N group) and 30 patients underwent classical mechanical debridement (M group). Complete wound healing over a period of 8 weeks occurred in 24 patients (27%) out of 90;10 patients belonging to the B group, 8 patients to the N group and 6 patients to the M group. This study was performed in order to highlight the differences between two commercially available collagenase-based ointments in comparison with mechanical debridement alone. At the final time point of week, the difference in the percentage of debridement was not statistically significant in all groups, but at 4 weeks, the debrided area in the B group was larger with respect to the N and M groups, suggesting a more rapid wound bed cleansing process. On the basis of our experience, collagenase derived from V. alginolyticus with hyaluronic acid showed chemical and physical properties that make it a product of great manageability and ensure the protection of peri-wound skin. Moreover, less pain was experienced by the patients., (© 2015 Medicalhelplines.com Inc and John Wiley & Sons Ltd.)

Foot infections in diabetic patients are a common, complex and costly problem. They are potentially adverse with progression to deeper spaces and tissues and are associated with severe complications. The management of diabetic foot infection (DFI) requires a prompt and systematic approach to achieve more successful outcomes and to ultimately avoid amputations. This study reviews a multi-step treatment for DFIs. Between September 2010 and September 2012, a total of about 37 patients were consulted for DFI. The treatment algorithm included four steps, that is, several types of debridement according to the type of wound, the application of negative pressure therapy (NPT), other advanced dressings, a targeted antibiotic therapy local or systemic as the case may, and, if necessary, reconstructive surgery. This treatment protocol showed excellent outcomes, allowing us to avoid amputation in most difficult cases. Only about 8% of patients require amputation. This treatment protocol and a multidisciplinary approach with a specialised team produced excellent results in the treatment of DFI and in the management of diabetic foot in general, allowing us to improve the quality of life of diabetic patients and also to ensure cost savings., (© 2014 The Authors.

Dermal substitutes offer alternative approaches for wounds of all thicknesses where sufficient donation sites are not available for self-grafts. Several dermal substitutes are described in literature. This study included 20 patients treated with a dermal induction template after the removal of malignant skin cancers situated in various parts of the body. The participants were especially aged patients with multiple skin cancers, and complex clinical conditions, often affected by pathologies such as cardiopathy, diabetes mellitus, and hypercholesterolaemia, and receiving pharmacological multi-therapies, particularly antiplatelets and anticoagulants. In many of these patients, the general complex clinical picture provided significant contraindication for complex reconstructive surgery because of the high risk involved. All patients achieved complete healing about 8 weeks after the first surgery. By using a dermal induction template, it was possible to cover substantial loss of substances without the need of autologous tissue, with smoother and less apparent scar, minor occurrence of hypertrophic and retracted scars, better flexibility of healed skin and therefore a better result from an aesthetic point of view., (© 2014 The Authors.

Some chronic ulcers often occur with slough, not progressing through the normal stages of wound healing. Treatment is long and other therapies need to be performed in addition to surgery. Patients not eligible for surgery because of ASA class (American Society of Anesthesiologists class) appear to benefit from chemical therapy with collagenase or hydrocolloids in order to prepare the wound bed, promoting the healing process. We describe four cases of traumatic, upper limb deep wounds caused by different physical and chemical agents, emphasising the effectiveness of treatment based on topical application of collagenase and hyaluronic acid (HA) before standardised surgical procedures. We performed careful disinfection of lesions combined with application of topical cream containing hyaluronic acid, bacterial fermented sodium hyaluronate (0·2%w/w) salt, and bacterial collagenase obtained from non-pathogenic Vibrio alginolyticus (>2·0 nkat1/g). In one patient a dermo-epidermal graft was used to cover the wide loss of substance. In two patients application of a HA-based dermal substitute was done. We obtained successful results in terms of wound healing, with satisfactory aesthetic result and optimal recovery of the affected limb functionality. Topical application of collagenase and HA, alone or before standardised surgical procedures allows faster wound healing., (© 2014 The Authors.

Background. Systemic sclerosis (SSc) is a multisystem disease characterized by cutaneous and visceral fibrosis. Face and mouth changes include telangiectasia, sicca syndrome, and thinning and reduction of mouth width (microcheilia) and opening (microstomia). We applied autologous fat transplantation compared with autologous adipose-derived stromal cells (ADSCs) injection to evaluate the clinical improvement of mouth opening. Methods. From February to May 2013 ten consecutive SSc patients were enrolled from the outpatient clinic of Plastic Surgery Department of Sapienza University of Rome. Patients were divided into two groups as follows: 5 patients were treated with fat transplantation and 5 patients received infiltration of ADSCs produced by cell factory of our institution. To value mouth opening, we use the Italian version of Mouth Handicap in Systemic Sclerosis Scale (IvMHISS). Mouth opening was assessed in centimetres (Maximal Mouth Opening, MMO). In order to evaluate compliance and physician and patient satisfaction, we employed a Questionnaire of Satisfaction and the Visual Analogic Scale (VAS) performed before starting study and 1 year after the last treatment. Results and Conclusion. We noticed that both procedures obtained significant results but neither one emerged as a first-choice technique. The present clinical experimentation should be regarded as a starting point for further experimental research and clinical trials.

Background: Caustic burns are burns of third and fourth degree caused by strong acids or strong bases. Muriatic acid is often used for suicidal attempt by ingestion. We describe a case of a caustic skin lesion caused by intravenous failed attempt of suicide by injection of Muriatic acid in a woman affected with bipolar-syndrome. Generally, caustic burns are treated by cleansing, escarectomy and coverage with skin grafts., Case Report: We treated the patient with a non invasive technique with collagenase and hyaluronic acid sodium salt cream (Bionect start®), hyaluronic acid-based matrix (Hyalomatrix®) and Vacuum-Assisted Closure (VAC) Therapy®., Results: We obtained complete healing in 6 weeks., Conclusions: Combined use of non invasive techniques seems to ensure only advantages for both the patients and the Health System. It reduces health care costs and risks for the patients such as nosocomial infections. Patient's compliance is high, as its quality of life. Complete healing of the wound is fast and recovery of function is full.

Non-invasive ventilation (NIV) provides an effective ventilatory support in patients with respiratory failure without endotracheal intubation. However, there are potential problems with its clinical application and the development of pressure ulcers represents a common complication. Often several intensive care units treat facial skin breakdown related to NIV. In this article, we report our experience in treatment and prevention of these lesions, emphasising the higher risk of certain age groups to develop them, such as preterm infants and elderly patients with comorbidities. We performed daily disinfection of the lesions followed by application of topical cream containing hyaluronic acid (HA) sodium salt. In addition, in order to prevent worsening of injury, we applied a cushion made of gauze pad containing HA sodium salt between the skin and the masks, so as to reduce friction between the NIV devices and the skin. Local medical treatment allowed complete reepithelialisation of the injured skin areas. Systematic monitoring of patients' faces is essential to detect early damages and to intervene with appropriate therapy, especially in preterm infants and elderly. Moreover, refining the devices with the proposed protective cushion can reduce pressure ulcers and increase comfort for the patients., (© 2013 The Authors.

Malignant degeneration of wounds is rare and often misdiagnosed. Delay in diagnosis may result in a worse prognosis. The aim of this study is to determine the number of skin cancers associated with chronic skin ulcers in our facility over a period of 10 years. Between January 2002 and December 2012, a total of about 1000 patients had consulted with us for chronic wounds, especially of vascular, diabetic and traumatic origin and pressure ulcers. Thirteen skin cancers had been detected: seven squamous cell and five basal cell carcinomas and one melanoma. We highlight how important it is to be aware of the signs suggesting a malignant change and the importance of biopsy at regular intervals during the life cycle of any chronic wound., (© 2013 The Authors.

The most frequent causes of leg ulcers include venous incompetency (superficial and deep), arterial insufficiency, trauma, vasculitis, and neoplasm. Leg ulcers from injury by stingrays are quite rare. In this case report, we describe a leg ulcer caused by a stingray sting complicated by infection, which healed completely without surgery. In addition, since there few cases in the literature describing such traumas, we performed a comprehensive review of the literature. Important is the fact that the wound healing was complete without resorting to surgery, but only with a correct targeted antibiotic therapy and the use of a collagenase, which has the particularity of having hyaluronic acid as a component., (© The Author(s) 2014.)

Sickle cell disease (SCD) is an inherited hemoglobinopathy characterized by a wide range of clinical manifestations. Chronic leg ulcers are a disabling complication with repercussions on the quality of life. We report the case of a 14-year-old girl with a diagnosis of SCD who developed a chronic leg ulcer that was successfully treated with a multi-disciplinary approach, including local and systemic therapies. The role of different treatments, in particular low molecular weight heparin, in the refractory chronic leg ulcer healing process will be discussed.

Aim: Congenital genitalia anomalies are a spectrum of malformation, difficult to classify because similar or identical phenotypes could have several different aetiology; therefore it's essential to assess an efficient diagnostic algorithm for a quick diagnosis and to develop an efficient therapeutic strategy. The aim of this study is to underline the importance of imaging in case of ambiguous genitalia due to its high sensitivity and specificity in detecting internal organs and urogenital anatomy., Material of Study: We report a case of a young girl affected by a complex genitor-urinary malformation with an initial wrong anamnesis that led to a tricky diagnosis., Results: Imaging techniques - especially Magnetic Resonance Imaging (MRI) - together with karyotype, hormones and physical investigations, offered complete and reliable informations for the best surgical treatment of our patient., Conclusion: Karyotype, hormones investigation, and radiological examinations are the main criteria considered in the diagnostic iter. Ultrasonography (US) is the primary modality for the detection of the presence or absence of gonads and müllerian derivatives, whereas Cystourethrography can define urethral and vaginal tract or the presence of fistulas. In our experience MRI, due to its multiplanar capability and superior soft tissue characterization, proved to be useful to provide detailed anatomic information.

The accidental leakage of the compound, in this case heroin, from the veins where it is injected, causes the formation of tissue lesions. Similar mechanisms lead to progressive tissue necrosis, which, if not immediately treated, results in the loss of the relevant function. A 57-year-old man presented a skin lesion on the posterior region of the left forearm with extensive necrosis of skin and subcutaneous layer involving the underlying muscle planes, caused by a venous extravasation of heroin that he reports having injected himself. The wound size is 15 × 10 cm; it had a sanious, fibrinous, secreting and smelly bottom. In this period, the patient was subjected to daily focused dressing before debridement of the lesion through a collagenase plus hyaluronic acid ointment: Bionect Start®; (FIDIA Pharmaceutical, Abano, Italy). The therapeutic choice was rewarded with a complete resolution of the wound through a non-invasive technique and over a short period. Avoiding the hospitalisation of the patient achieved a reduction of risks for him and of the costs for the National Health Service (NHS). The Bionect Start®; (FIDIA Pharmaceutical) as well as allowing the healing of the wound also decreased significantly the pain felt by the patient, the amount of exudate and the bad smell improving in a non-negligible way his quality of life., (© 2012 The Authors.
