Since its first description in 1908, the sternocleidomastoid flap (SCM) has gained popularity in head-and-neck reconstruction as a regional flap. We reported a 69-year-old Caucasian male who was evaluated in our clinic for a large, bloody, esophitic, and ulcerated lesion of the right temporoparotideal region associated with several actinic keratoses of the head skin. After resection of the tumor, taking into consideration the patient’s comorbidities and surgical defect characteristics, we decided to use the SCM flap for the reconstruction. The SCM flap was harvested as a muscular flap to avoid as possible skin paddle necrosis due to the poor conditions of the patient’s vessels. Moreover, considering the surgical site depth and to prevent a postsurgical excessive scar retraction, the muscle was covered with Integra® Dermal Regeneration Template single layer and a skin graft was harvested from the left thigh. The follow-up at 1 year confirmed that both oncological and reconstructive goals were successfully achieved. In our experience, the SCM flap in association with a dermal regeneration template and a skin graft can be considered as a reliable and possible option in temporal region reconstruction when local or systemic conditions of the patient do not permit other reconstructive options.

- Abstract
Treatment of infected wounds remains a major challenge for clinicians. Antimicrobial stewardship is an important pillar in wound treatment and, as the role of bacteria in wound repair is not well understood, new treatment options and products are constantly being developed to tackle local infection and biofilm. This case report describes a case of antibiotic-resistant Burkholderia cepacia skin infection and subsequent leg ulceration in an 86-year-old man during the COVID pandemic in Italy, which was successfully treated in a conservative way using 1% acetic acid and silver oxysalts in conjunction with compression bandage.

- Abstract
Background: The impact of carotid stenosis (CS) in patients undergoing cardiac surgery remains controversial. The aim of this study was to evaluate the association between carotid stenosis and stroke and/or transient ischemic attack (TIA) in patients undergoing cardiac surgery on cardiopulmonary bypass., Methods: This was a retrospective cohort study including patients undergoing cardiac surgery on cardiopulmonary bypass from January 2006 to March 2018 at the Québec Heart and Lung Institute. Data of patients' preoperative demographic characteristics, operative and postoperative variables were taken from a computerised database and patients' charts. Univariate and multivariate analyses were performed., Results: A total of 20,241 patients were included in the study. Among those who had received preoperative carotid ultrasound, 516 (2.6% of the total population) had unilateral or bilateral CS ≥ 50%. Categorised levels of CS severity were identified as independent risk factors for postoperative stroke and/or TIA. There was an almost 3-fold increased risk of postoperative neurologic events in 80%-99% CS vs less severe 50%-79% CS (odds ratio 2.91, 95% confidence interval 1.30-6.54), suggesting that the degree of severity of CS is potentially a strong independent predictor of postoperative neurologic events., Conclusions: CS is an independent risk factor of postoperative stroke and/or TIA. This study suggests for the first time that the risk of stroke increases with the degree of severity of CS, with the greatest risk being for CS of 80%-99%. The strength of this relationship and potential causality effect should be further explored in a prospective study focusing on this population most at risk., (Copyright © 2021 Canadian Cardiovascular Society.

- Abstract
Upper extremity body reshaping is a very frequent surgical procedure in massive weight loss patients. Many surgeons have presented different patterns of brachioplasty skin excision and a variety of adjunctive techniques, each of them claiming improvements in scar aesthetic, arm shape or overall safety of the procedure. In this pape,r we want to illustrate our personal brachioplasty technique for massive weight loss patients. Our incision design named 'J' Brachioplasty is described. Between March 2013 and March 2016, a retrospective study of patients with massive weight loss and clinical diagnosis of brachial ptosis undergoing surgical reconstruction with 'J' brachioplasty was performed. All patients were treated according to a standard surgical procedure described in detail in the paper. The presence of axillary and thoracic skin excess was also recorded for every subject, as well as clinical and surgical postoperative complications. A total number of 73 Caucasian underwent J-shaped brachioplasty. Our technique allowed us to treat both arm and thoracic skin excess with a single skin incision. Among our casuistic we had only two cases of postoperative bleeding and four cases of partial wound dehiscence due to tension. Seroma was reported only in one (female) patient. Despite the recent introduction our technique has proven to reach good results in massive weight loss patients.

- Abstract
Chronic wounds are commonly associated with high morbidity rates due to the patient's need of frequent dressing changes and repeated visits to the outpatient wound clinic. Furthermore, chronic wounds are often characterised by severe pain, which can cause significant disability to the patient. New technologies aim to develop an optimal device to reduce discomfort of the patient and to heal wounds. The device Rexon-age
® is introduced for the first time in wound healing, and preliminary data on clinical and histological results are shown. From April 2014 to April 2015, 11 patients - 7 females and 4 males - were enrolled in the present study. The study was conducted at the Plastic and Reconstructive Institute of the Università degli Studi di Torino, Città della Salute e della Scienza of Torino, Italy. For histological characterisation, pre- and post-treatment biopsies on the wound bed were performed. Data regarding age, gender, weight, height, comorbidity, drug therapy and topical pre-treatment and dressings of the wound were collected as well. Moreover, local factors regarding the wound data were as follows: aetiology, time of the wound formation until first Rexon-age treatment, wound dimensions, wound bed, moisture, margins and anatomical region of the wound. A visual analogue scale (VAS) was used to monitor the pain before and after each treatment. Rexon-age treatment resulted in improvement in granulation tissue and wound contraction. Moreover, a significant reduction of pain was observed with the reduction of painkillers drug usage. Among these Rexon-age-treated patients, three patients displayed 60-80% reduction in pain intensity, and two patients showed complete pain relief. In outpatient follow-up appointments, we registered long-term durability of pain relief. As assessed by histological analyses, post-treatment biopsies of all nine patients revealed a decreased amount of inflammatory cells and lower expression levels of metalloproteinases (e.g. MMP9). We observed increased capillary thrombosis as well as up-regulation of vascular endothelial growth factor (VEGF) expression. The current study presents the first evidence that Rexon-age-based therapy can significantly ameliorate and accelerate the healing process of chronic wounds. Although this study analysed only a small number of patients, we could consistently observe positive effects on both the clinical aspect of the lesions, which underwent size reduction and wound reactivation, and the quality of life of our patients due to long-term pain relief., (© 2017 Medicalhelplines.com Inc and John Wiley & Sons Ltd.)- Published

- Abstract
Objectives: The prevalence of obesity has risen in the last decade, increasing the percentage of obese patients who undergo cardiac surgery. Deep sternal wound infection (DSWI) is a rare but devastating postoperative complication, more often encountered in the obese population. DSWI is also associated with the use of bilateral internal mammary artery (BIMA), particularly in this high-risk population. The aim of this study is to determine the short-term and long-term outcomes following BIMA revascularization in obese patients., Methods: This is a single-centre retrospective cohort study using prospectively collected data including all obese patients who underwent coronary artery bypass grafting (CABG) surgery between April 1991 and April 2014. Preoperative demographic characteristics, operative and postoperative variables were taken from the computerized database of the hospital. A propensity score matching was conducted for the short- and long-term outcomes in the entire study population., Results: Results showed that 5608 patients with a body mass index of ≥30 kg/m
2 underwent CABG during the studied period. After propensity scoring, 494 patients receiving BIMA were matched to 5089 patients receiving single internal mammary artery (SIMA). All preoperative characteristics were comparable except for a higher prevalence of left ventricular dysfunction and left main disease as well as higher mean EuroSCORE in the SIMA group. In the postoperative period, short-term mortality was comparable in the two groups (P = 0.68). In-hospital DSWI was also comparable (P = 0.10). However, when considering DSWI occurring after hospitalization (median time; 19 days), the latter was significantly lower in the SIMA than in the BIMA group (1.1 vs 3.2%; P < 0.0001). For long-term survival, no difference was observed between the BIMA and SIMA groups after appropriate matching (P = 0.22)., Conclusions: In obese patients, CABG surgery using BIMA instead of SIMA increased the risk of postoperative DSWI, without improving survival. According to our results, short-term postoperative risks of infection associated with BIMA are not offset by longer-term benefits in that patient population. Special care should be exerted when selecting conduits for myocardial revascularization in obese patients., (© The Author 2016.

- Abstract
The postoperative dressing in patients undergoing thigh lift is often difficult, not very resistant to movement, and uncomfortable for the patient, and often exposes surgical site to infection, maceration, or delay in wound healing., Methods: We included 40 patients in a case-control crossover study with no period effects, who were treated both by Aquacel Surgical and a traditional wound dressing. Surveys with a 10-point scale evaluation were used to assess nontraumatic removal level, ease of application, adhesion, and strength of the 2 treatments. We reported the number of days necessary for wound healing, the number of infection cases, and wound-related complications. Costs of the 2 medications were also considered. Ten days after surgery, patients answered a questionnaire with 6 multiple-choice questions to assess comfort, pain at dressing change, pruritus, strength, and number of dressing changes., Results: Compared with controls, surveys revealed Aquacel Surgical to be less traumatic to remove, easier to apply, and to be more adherent and stronger. Significant acceleration of the wound healing was also evident with Aquacel Surgical compared with the traditional dressing. Nonsignificant differences were reported about the risk of infection and wound-related complications between the 2 treatments. A statistical analysis of costs revealed that Aquacel Surgical is significantly more expensive than the traditional medication., Conclusion: We recommend the use of Aquacel Surgical in all the surgery procedures where the risk of wound dehiscence and maceration is high., Competing Interests: The authors have no financial interest to declare in relation to the content of this article.

- Abstract
Acquired scrotal giant muscular hamartoma is an uncommon benign lesion with fewer than 10 documented cases all over the world. It is characterized by a proliferation of dermal smooth muscle bundles of scrotum dartos fascia. The authors report a rare case of acquired scrotal giant muscular hamartoma, which occurred in a 70-year-old severely obese and diabetic man presenting with a progressive scrotal enlargement and swelling in the last year, causing marked reduction in quality of life and cosmetic problems. The patient underwent a wide excision of the hamartomatous lesion, and then, a reductive scrotoplasty and autologous skin grafting of penis were performed. Anatomopathological examination showed an acquired scrotal giant muscular hamartoma arising from muscular fascia of dartos. This surgical technique is a valid, safe, effective, and minimally invasive option to treat this pathology, achieving both excellent functional and aesthetic results, with a marked improvement of the patient's quality of life., Competing Interests: The authors have no financial interest to declare in relation to the content of this article.

- Abstract
With the increasing prevalence of obesity, clinicians are now facing a growing population of patients with specific features of clinical presentation, diagnostic challenges, and interventional, medical, and surgical management. After briefly discussing the effect of obesity on atherosclerotic burden in this review, we will focus on strategies clinicians might use to ensure better outcomes when performing revascularization in obese and severely obese patients. These patients tend to present comorbidities at a younger age, and their anthropometric features might limit the use of traditional cardiovascular risk stratification approaches for ischemic disease. Alternative techniques have emerged, especially in nuclear medicine. Positron emission tomography-computed tomography might be the diagnostic imaging technique of choice. When revascularization is considered, features associated with obesity must be considered to guide therapeutic strategies. In percutaneous coronary intervention, a radial approach should be favoured, and adequate antiplatelet therapy with new and more potent agents should be initiated. Weight-based anticoagulation should be contemplated if needed, with the use of drug-eluting stents. An "off-pump" approach for coronary artery bypass grafting might be preferable to the use of cardiopulmonary bypass. For patients who undergo bilateral internal thoracic artery grafting, harvesting using skeletonization might prevent deep sternal wound infections. In contrast to percutaneous coronary intervention, lower surgical bleeding has been observed when lean body mass is used for perioperative heparin dose determination., (Copyright © 2015 Canadian Cardiovascular Society.

- Abstract
Osteomyelitis of the calcaneus is a difficult problem to manage. Patients affected by osteomyelitis of the calcaneus often have a below-the-knee amputation because of their comorbidity. In this article, we present seven cases of heel ulcerations with chronic osteomyelitis treated with Integra(®) Dermal Regeneration Template, skin graft and negative pressure wound therapy after partial tangential calcanectomy, discussing the surgical and functional results. In this casuistic of patients, all wounds healed after skin grating of the neodermis generated by Integra(®), with no patient requiring a below-knee amputation., (© 2011 The Authors. © 2011 Blackwell Publishing Ltd and Medicalhelplines.com Inc.)

- Abstract
Wounds can be caused by different mechanisms and have a significant morbidity and mortality. Negative pressure wound therapy (NPWT) is one of the most successful treatment modalities for wound healing. We have been using both foam and gauze-based NPWT. During application of NPWT, we noticed that the patient's pain was of varying intensity depending on the filler used. The aim of our work was to compare the level of pain and feedback before, during the treatment and at the dressing change after treatment with NPWT with two different fillers. For this study, we compared a pool of 13 gauze-treated patients with a pool of 18 foam-treated patients regarding the level of pain and feedback before, during the treatment and at the dressing change after treatment with NPWT. They were all post-traumatic patients with loss of tissue up to the muscular band. The patients were asked to respond to a questionnaire interviewed by the same physician to assess the level of pain using VNS (verbal numerical scale). We observed similar difference of means before and during the treatment with NPWT with gauze and foam. Regarding the pain at the dressing change, the mean of the scores for the foam was 6·5 while for the gauze was 4·15. In this case, we noticed the most significant difference between means from the scores given: 2·35 which was a statistically significant difference between the two groups (P = 0·046). The finding of this study confirms less pain at the dressing change after treatment with gauze-based NPWT. In our opinion, this finding is related to the more adhesive property of the foam probably because of the ingrowth of the granulation tissue in the micropores present on the foam. Considering this statement, we recommend the foam for neuropathic and paraplegic patients and the gauze for patients with bone and tendon exposition wounds, patients that do not tolerate NPWT with foam and low compliant patient particularly paediatric and old-age patients. We remind that the performance of this study was not sponsored by any company., (© 2011 The Authors. © 2011 Blackwell Publishing Ltd and Medicalhelplines.com Inc.)

- Abstract
Negative pressure wound therapy (NPWT) is becoming routine for the preparation of wounds prior to grafting for wound closure. We have been using both foam- and gauze-based NPWT to prepare wounds for closure prior to skin grafting and have obtained similar proportions of closed wounds; 7/7 for wounds treated with gauze-based NPWT and 11/11 for wounds treated with foam-based NPWT. In our follow-up consultations we observed that skin grafts on the foam-treated patients were less pliable than those on the gauze-treated patients. To assess what the mechanism of this effect might be, we compared the specific details of the treatments of both 11 foam and 7 gauze patients, including depth, location, patients' age and co-morbidity; biopsies of granulation and scar tissue were taken and stained with haematoxylin-eosin and by Masson's trichrome staining and conducted ultrasound analysis of the closed wounds, to see if there were features which explained those effects. All foam patients were treated at -125 mm Hg for an average of 25·9 days before skin grafts were applied. All gauze patients were treated at -80 mm Hg for an average of 24·7 days before skin grafts were applied. Biopsies of granulation tissue prior to skin grafting from five foam and four gauze-based NPWT patients did not reveal any obvious histological differences between the treatments. Ultrasound analysis of the skin-grafted wounds showed an average depth of scar tissue of 18 mm in the wound beds of the foam-treated wounds and 7 mm in the gauze-treated ones. Biopsies taken on the scar tissue after treatment with the gauze showed a minor tissue thickness and disorganisation and less sclerotic components. The findings of this preliminary analysis suggest that foam-based NPWT may induce a thicker layer of scar tissue beneath skin grafts than gauze-based NPWT which might explain a reduced pliability of the reconstructed bed. At present it is unclear which mechanism might be responsible for the difference in pressure (-125 versus -80 mm Hg), either the length of the time taken to reconstruct the wound bed or the intrinsic nature of the foam or gauze on the tissue surface. Prospective studies are necessary to investigate whether these preliminary observations are confirmed and to investigate what the mechanism might be., (© 2011 The Authors. © 2011 Blackwell Publishing Ltd and Medicalhelplines.com Inc.)

- Abstract
Surgical debridement, which is used for the removal of necrotic tissue from a wound, is becoming more and more important in the treatment of skin injuries. VERSAJET (VERSAJET™, Versajet Hydrosurgery System, Smith and Nephew, Hull, UK) is one of the techniques used for wound debridement. Medical literature does not present either analytical or comparative data correlating the bacterial load with the VERSAJET treatment. For this reason, we have decided to carry out a study to evaluate the level of bacterial contamination before and after the surgical debridement treatment with VERSAJET and, in connection with this, the correlation between the bacterial load and the successful healing of the skin graft. We took a total of 100 bacteriological swabs, 50 before and 50 from 27 selected patients after the treatment with VERSAJET, with which the wound bed was prepared to receive the skin graft or Integra graft in order to acquire data about the level of bacterial contamination. After analysing all those data we can assume that reducing the bacterial load is not the only variable which the successful healing of the skin graft depends on. In conclusion, there is still many data to analyse and study in order to better understand the qualitative and quantitative presence of bacteria and the success of this future surgical procedure. We remind that the performance of this study was not sponsored by any company., (© 2011 The Authors. © 2011 Blackwell Publishing Ltd and Medicalhelplines.com Inc.)

- Abstract
The regulation of nerve growth factor (NGF) production is still poorly understood. We attempt here to determine whether brown adipose tissue (BAT), which is densely innervated by sympathetic nerve fibres and can be induced to grow in adult rats by simple cold exposure, has the ability to produce NGF and thus to stimulate the growth of its innervation and, if so, whether this NGF activity is developmentally regulated. BAT at various stages of development was cocultured with NGF-sensitive sympathetic ganglia in the presence or absence of antiserum to NGF. Both undifferentiated BAT from newborn hamster and differentiated BAT from newborn rat induced neurite outgrowth by producing a neurotrophic factor which was biologically and immunologically indistinguishable from mouse submandibular gland beta (2.5S) NGF. Newborn hamster BAT and BAT from adult rats exposed to cold for 1 or 2 days showed the same high level of NGF activity, whereas the activities of newborn rat BAT, BAT from adult rats at normal room temperature or cold-exposed for 3 days or more were not significantly different from each other and were only about half as high. Newborn hamster BAT and BAT from adult rats cold-exposed for 1 or 2 days are both characterized in vivo by a rapidly increasing mitotic activity of the stromal-vascular cells, which distinguishes them from the other developing tissues tested. Our observations, therefore, suggest a relationship between NGF synthesis and proliferative activity.
