Abstract
Chronic wounds pose a significant clinical challenge due to their complex pathophysiology and the burden of long-term management. Monoclonal antibodies (mAbs) are emerging as a novel therapeutic option in managing difficult wounds, although comprehensive data on their use in wound care are lacking. This study aimed to explore existing scientific knowledge of mAbs in treating chronic wounds based on a rationale of direct inhibition of the main molecules involved in the underlying inflammatory pathophysiology. We performed a literature review excluding primary inflammatory conditions with potential ulcerative outcomes (e.g., hidradenitis suppurativa). mAbs were effective in treating wounds from 16 different etiologies. The most commonly treated conditions were pyoderma gangrenosum (treated with 12 different mAbs), lipoid necrobiosis, and cutaneous vasculitis (each treated with 3 different mAbs). Fourteen mAbs were analyzed in total. Rituximab was effective in 43.75% of cases (7/16 diseases), followed by tocilizumab (25%, 4/16 diseases), and both etanercept and adalimumab (18.75%, 3/16 conditions each). mAbs offer therapeutic potential for chronic wounds unresponsive to standard treatments. However, due to the complex molecular nature of wound healing, no single target molecule can be identified. Therefore, the use of mAbs should be considered as a translational approach for limited cases of multi-resistant conditions.

Abstract
Chronic wounds are characterized by their inability to heal within an expected time frame and have emerged as an increasingly important clinical problem over the past several decades, owing to their increasing incidence and greater recognition of associated morbidity and socio-economic burden. Even up to a few years ago, the management of chronic wounds relied on standards of care that were outdated. However, the approach to these chronic conditions has improved, with better prevention, diagnosis and treatment. Such improvements are due to major advances in understanding of cellular and molecular aspects of basic science, in innovative and technological breakthroughs in treatment modalities from biomedical engineering, and in our ability to conduct well-controlled and reliable clinical research. The evidence-based approaches resulting from these advances have become the new standard of care. At the same time, these improvements are tempered by the recognition that persistent gaps exist in scientific knowledge of impaired healing and the ability of clinicians to reduce morbidity, loss of limb and mortality. Therefore, taking stock of what is known and what is needed to improve understanding of chronic wounds and their associated failure to heal is crucial to ensuring better treatments and outcomes.

Abstract
Inflammatory wounds of the skin can be caused by many different diseases. Of particular importance here are the very heterogeneous groups of vasculitides and vasculopathies. These are usually interdisciplinary relevant diseases that require extensive diagnostics in specialized centres. Clinically, these inflammatory wounds present as very painful ulcers that develop from necrosis and are surrounded by erythematous livid borders. The healing process is often difficult and protracted. Moreover, it considerably impairs the quality of life of the affected patients. In addition to clinical evaluation, histopathological examination of biopsies taken as early as possible is particularly important in diagnosis. Numerous differential diagnoses must be ruled out. Therapeutically, in addition to the often necessary systemic therapies, which include immunosuppressants (immunomodulating drugs and/or rheologics), appropriate topical wound treatment, usually in combination with compression therapy, should always be considered. Whenever possible, the causative factors should be diagnosed early and avoided or treated.

Abstract
Pyoderma gangrenosum (PG) is a neutrophilic dermatosis which may be rapidly progressive. Standard guidelines for local treatment are lacking. Through our experience, we suggested a local treatment algorithm based on the tissue, infection, moisture balance, and epithelization (TIME) concept. The clinical and histopathological features of 52 patients with PG, the duration, and the evolution of the lesions were retrospectively evaluated. Systemic therapies, local treatments, and standard wound treatments were reported. We observed ulcerative PG in the majority of the patients (82.6%), followed by the pustular form (9.6%), the peristomal type (3.8%), the vegetative form (1.9%), and the bullous type (1.9%). The lower leg was the most commonly area affected (90.4% of cases). Pathergy was reported in 15.3% of cases. The first-line treatment was the use of oral glucocorticosteroids (GCSs). We observed healing after 3 weeks of GCS in 17.3% of cases. In 25% of all cases, we obtained complete healing with long-term low doses (<0.5 mg/kg) of GCS in the range of 2 to 6 months. We used second-line treatments in 57.6% of patients. Local, systemic treatment, and correct wound management can be associated with better clinical results. We suggest a new local therapeutic algorithm in both the inflammatory and noninflammatory healing phases.

Abstract
Atypical ulcers show atypical clinical features, histology, localization, and resistance to standard therapies. The persistence of a chronic ulcer despite treatment with standard therapies requires a more specific diagnostic investigation. Diagnosis involves obtaining the history and performing clinical examination and additional tests. A skin biopsy is frequently used to confirm unclear diagnosis. In difficult cases, microbiological and immunohistochemical examinations, laboratory blood tests, or instrumental tests should be evaluated. The treatment of atypical wounds is characterized by local systemic therapy and pain control. Our results highlight the need for early diagnosis, and standardized and targeted management by a multidisciplinary wound healing center.

Abstract
Pyoderma gangrenosum (PG) is a rare ulcerative skin disease that presents a therapeutic challenge. Tumour necrosis factor alpha (TNFα) inhibitors have been reported to successfully control PG. Our aim was to systematically evaluate and compare the clinical effectiveness of TNFα inhibitors in adults with PG. A literature search including databases such as PubMed, Embase, Scopus, and Web of Science was conducted, using search terms related to PG and TNFα inhibitors. Studies and case reports were included if patients were diagnosed with PG, over the age of 18 and administered TNFα inhibitor. A total of 3212 unique citations were identified resulting in 222 articles describing 356 patients being included in our study. The study we report found an 87% (95% CI: 83%-90%) response rate and a 67% (95% CI: 62%-72%) complete response rate to TNFα inhibitors. No statistically significant differences in the response rates (P = 0.6159) or complete response rates (P = 0.0773) to infliximab, adalimumab, and etanercept were found. In our study TNFα inhibitors demonstrated significant effectiveness with response and complete response rates supporting the use of TNFα inhibitors to treat PG in adults. Our study suggests that there is no significant difference in effectiveness among infliximab, adalimumab, and etanercept.

Abstract
In the last decades the possibility to diagnose a skin ulcer has greatly improved. We learnt that a consistent percentage of nonhealing ulcers may be caused by a microangiopathic disorder that has not been properly investigated and cured. Pathogenetically, we can distinguish 2 main groups: (1) ulcers due to inflammatory microangiopathy, mainly including cutaneous small and medium vessel vasculitis, pyoderma gangrenosum, and connective tissue diseases, and (2) ulcers due to occlusive microangiopathy. The group of microangiopathic occlusive ulcers is more heterogeneous and includes different disorders ranging from livedo vasculopathy to calciphylaxis, hydroxyurea-induced ulcers, antiphospholipid antibodies ulcers, and various other types. These conditions can induce thromboses or anatomo-functional occlusion of cutaneous microvessels. Despite different physiopathologic mechanisms, the ulcer resulting from a primitive microangiopathy may receive basic treatments that are in the complex similar to other pathogenetically different wounds, including MOIST-based local therapy and elastic compression when it is not contraindicated. Persistent inflammatory processes are increasingly demonstrated as responsible for the chronicity of many skin ulcers. New data concerning the biological phases of wound healing and the molecules that play crucial roles in this process suggested the use of new specific therapies. Some of them such as growth factors and platelet-rich plasma are prevalently used as topical biologic agents with variable benefits. In recent years, a new class of systemic anti-inflammatory molecules, better known as biologic drugs, have been introduced in the cure of chronic inflammatory diseases that can induce microangiopathic injuries and ulcerative complication. They enlarged the therapeutic options in case of nonresponder microangiopathic ulcers and could represent a future model of “pathogenetically based” therapy of skin ulcers.

Abstract
Pyoderma gangrenosum (PG) is an uncommon inflammatory skin disorder characterized by neutrophil dysfunction. There are currently no FDA-approved drugs for the treatment of this disease, and treatment has typically relied on traditional immunosuppressive medications such as prednisone or cyclosporine. The efficacy of biologics in the treatment of other pro-inflammatory conditions such as psoriasis, rheumatoid arthritis, and inflammatory bowel disease is well-documented in the literature. Therefore, the use of biologic medications for the treatment of rarer inflammatory skin conditions, such as PG, is a compelling topic for investigation. Biologic and small-molecule therapies allow physicians to target specific pro-inflammatory mediators that underlie PG pathogenesis. This review provides an update on the use of biologic and small-molecule medications for the treatment of PG and summarizes the latest data on the clinical efficacy and pharmacology of these treatments.

Abstract
Wound assessment is usually performed in hospitals or specialized labs. However, since patients spend most of their time at home, a remote real time wound monitoring would help providing a better care and improving the healing rate. This review describes the advances in sensors and biosensors for monitoring the concentration of C-reactive protein (CRP), temperature and pH in wounds. These three parameters can be used as qualitative biomarkers to assess the wound status and the effectiveness of therapy. CRP biosensors can be classified in: (a) field effect transistors, (b) optical immunosensors based on surface plasmon resonance, total internal reflection, fluorescence and chemiluminescence, (c) electrochemical sensors based on potentiometry, amperometry, and electrochemical impedance, and (d) piezoresistive sensors, such as quartz crystal microbalances and microcantilevers. The last section reports the most recent developments for wearable non-invasive temperature and pH sensors suitable for wound monitoring.

Abstract
Pyoderma gangrenosum (PG) is a rare neutrophilic inflammatory skin disease, characterized by recurrent skin ulcers, which in almost 50% of cases are associated with systemic autoimmune disorders, including rheumatoid arthritis, chronic hepatitis, inflammatory bowel disease, paraproteinemias and hematological malignancies. A systematic search of literature for PG was carried out using the PubMed, Embase, and Google Scholar databases for the purpose of this review and 2780 articles were retrieved up to February 2017. Inflammation represents the predominant aspect of the disease, but its pathophysiological mechanisms are not completely clear yet, since there are many studies showing only one or more isolated findings of the disease. The goal of PG treatment is to reduce inflammation in order to promote ulcer healing by minimizing side effects of therapy. Several systemic and local treatments are available, but the lack of large randomized double-blind studies results in an absence of a uniform therapeutic standard: thus, more clinical studies are required in order to make head-to-head comparisons between combination and single-drug therapies and to identify specific combination therapies for distinctive clinical patterns of PG.

Abstract
The aim of this study was to document the profile of pyoderma gangrenosum (PG) patients who were treated in our clinic and to compare our patients' clinical and demographic characteristics with those described in the literature to help our understanding of the total burden of PG. A total of 27 (17 women, 10 men) patients with a mean age 48.6 years at diagnosis were included in the study. Seven (25.9%) of them had 3 or more ulcers. The lower extremity was the most common site of occurrence (92.5%). During the study period, 6 patients were admitted twice, and 7 were admitted 3 or more times (range 1 to >10), and the median length of stay was 27 days. A concomitant disease was present in PG patients especially in those between 20 and 40 years of age. Systemic therapy was used in 21 (91.3%) patients, 17 patients were treated with systemic corticosteroids, either alone in 7 patients or combination with other agents in 10 patients. Three of our patients died because of disease or treatment-related complications during the study period. Despite the high (70.3%) percentage of the PG patients with improving disease at the time of discharge, 1 year after hospital discharge, one third of our 27 patients still had PG requiring readmission. In conclusion, none of the current therapies provide satisfying results in all of the patients, and our data indicate a long-standing unmet need for effective therapy for the unexpected course of PG.

Abstract
Pyoderma gangrenosum (PG) is an ulcerating noninfectious disease of the skin seen in 1-2% of patients with inflammatory bowel disease (IBD). The pathogenesis of PG has yet to be determined, but may be related to abnormal T cell responses and the production of TNF-α, a pathway also involved in IBD pathogenesis. Infliximab, a chimeric monoclonal antibody to TNF-α, is used to treat moderate to severe IBD and several case reports and studies suggest the efficacy of infliximab in the treatment of PG. The surgical approach to PG is reserved to a few selected cases. We report here the case of a patient with ulcerative colitis (UC) and PG localized on the left breast, treated with a simultaneous combined medical and surgical approach.

Abstract
Amelogenins are extracellular matrix proteins that, under physiological conditions, self-assemble into globular aggregates up to micron-sizes. Studies with periodontal fibroblasts indicate that attachment to these structures increases the endogenous secretion of multiple growth factors and cell proliferation. Pre-clinical and clinical studies indicate that cutaneous wounds benefit from treatment with amelogenins. A randomized controlled trial (RCT) involving patients with hard-to-heal venous leg ulcers (VLUs) (ie, ulcers with a surface area ≥10 cm2 and duration of ≥6 months) showed that the application of amelogenin (Xelma®, Molnlycke Health Care, Gothenburg, Sweden) as an adjunct treatment to compression results in significant reduction in ulcer size, improvement in the state of ulcers, reduced pain, and a larger proportion of ulcers with low levels of exudate, compared with treatment with compression alone. Amelogenin therapy was also shown to be safe to use in that there were no significant differences in adverse events noted between patients treated with amelogenin plus compression and those treated with compression alone. Case study evaluations indicate that the benefits of amelogenin therapy demonstrated in the RCT are being repeated in “real life” situations and that amelogenin therapy may also have a role to play in the treatment of other wound types such as diabetic foot ulcers.
