RESUMO
INTRODUCTION: Skin-sparing mastectomy (SSM) entails complete removal of the breast tissue and the nipple and areola complex (NAC) with preservation of as much of the overlying skin as possible. The preservation of the natural skin envelope during SSM improves the aesthetic outcome of immediate breast reconstruction, but the lack of NAC determines that the reconstructed breast remains anatomically incomplete with not always satisfactory final results. For this purpose, the aim of the present study was to investigate and evaluate the impact of nipple reconstruction after skin sparing and skin reducing mastectomy on the patients' perception and intimate life. MATERIALS AND METHOD: This was a comparative single-center prospective study that involved 42 patients underwent NAC reconstruction after SSM. A pre- and postoperative quality-of-life and psychological questionnaires Breast-Q questionnaire (Breast Conserving therapy module) were given to all the patients before the surgery and 6 months after. The statistical analysis with chi-square test was performed. RESULTS: After 6 months a prevalence of patients reported to be very satisfied in regard to shape, appearance, naturalness, projection, position and symmetry. The study shows an overall improvement in all the psychological items analyzed with statistically significant difference regarding: "patient's satisfaction," "self-confidence," "appearance of the breast." CONCLUSION: The authors believe that the NAC reconstruction has useful functional and aesthetic results particularly appreciated by patients who feel demoralized after breast demolition surgery.

Nonhealing wounds place a significant burden on both quality of life of affected patients and health systems. Skin substitutes are applied to promote the closure of nonhealing wounds, although their efficacy is limited by inadequate vascularization. The stromal vascular fraction (SVF) from the adipose tissue is a promising therapy to overcome this limitation. Despite a few successful clinical trials, its incorporation in the clinical routine has been hampered by their inconsistent results. All these studies concluded by warranting pre-clinical work aimed at both characterizing the cell types composing the SVF and shedding light on their mechanism of action. Here, we established a model of nonhealing wound, in which we applied the SVF in combination with a clinical-grade skin substitute. We purified the SVF cells from transgenic animals to trace their fate after transplantation and observed that it gave rise to a mature vascular network composed of arteries, capillaries, veins, as well as lymphatics, structurally and functionally connected with the host circulation. Then we moved to a human-in-mouse model and confirmed that SVF-derived endothelial cells formed hybrid human-mouse vessels, that were stabilized by perivascular cells. Mechanistically, SVF-derived endothelial cells engrafted and expanded, directly contributing to the formation of new vessels, while a population of fibro-adipogenic progenitors stimulated the expansion of the host vasculature in a paracrine manner. These data have important clinical implications, as they provide a steppingstone toward the reproducible and effective adoption of the SVF as a standard care for nonhealing wounds.
RESUMO
INTRODUCTION: Breast-conserving surgery (BCS) is a valid method for the reconstruction of partial breast defects, however, there is a great variety of final aesthetic outcomes depending on the location of the tumor in the breast and also on the initial breast volume and the degree of ptosis. Specifically, defects affecting the upper inner/central quadrant represent a reconstructive challenge with not always satisfactory final results. For this purpose, the authors investigated the use of the central mound technique in breast-conserving surgery. The aim of the study was to apply the central mound as an oncoplastic technique and assess the satisfaction rate of the patients. MATERIALS AND METHODS: This was a retrospective study that involved 40 patients (80 breast) underwent breast conserving surgery and contextual bilateral breast remodeling with central mound technique. A pre- and postoperative Breast-Q questionnaire (breast conserving therapy module) was given to all the patients before the surgery, 3 months and 9 months after. The statistical analysis with chi-square test was performed. RESULTS: After 9 months the author found a major increase of all BREAST-Q parameters; the most valuable increments concerned the "Satisfaction with breast" and "Psychosocial well-being." None of the patients experienced a decreased in the quality of life related to the surgical procedure. CONCLUSION: The authors believe that this technique has useful functional and aesthetic results particularly appreciated by patients with upper pole lesion who have a slightly or moderately breast ptosis and a small cup size.

BACKGROUND: Lidocaine hydrochloride is frequently used for management of painful wounds. This prospective, multicentre study examined the effects of 5% lidocaine cream on wound pain relief. MATERIAL AND METHODS: The study included 78 patients with painful wounds treated with 5% Lidocaine cream for two weeks in two Italian Hospitals. Patients' perception of pain was recorded by, using the 5-point Visual Rate Scale and the 11-point Numerical Pain Rating Scale. All medications and adverse events were evaluated in a daily diary. The primary outcome of the study was establishing the wound pain relief based on the results of 5-VRS and pain intensity based on the 11-NPRS testing from baseline to the end of treatment. Clinical aspects and adverse events were also collected. RESULTS: Seventy-eight patients had a median age of 67.5 years (range 18-96 years). 62.8% were women. The wounds included traumatic wounds (n = 39), venous ulcers (n = 25), post-surgical wounds (n = 6) pyoderma gangrenosum (n = 6), vasculitis (n = 1) and pressure ulcer (n = 1). The intensity of pain significantly decreased from the baseline level established at the beginning of treatment (mean score 6.7 - 1.90) - to the level at end of treatment (3.0 - 2.23-; p < 0.0001). 9 patients prematurely stopped the treatment for healing (n = 4), wound improvement (n = 2) and adverse events related to the treatment. (n = 3). 13 patients presented a total of 25 adverse events, 4 of them were related to the treatment. CONCLUSION: The treatment of painful wounds with 5% Lidocaine Cream for 14 days resulted in reduced pain intensity, and showed high safety and tolerability.

The loss of skin integrity has always represented a major challenge for clinicians dealing with dermal defects, such as ulcers (diabetic, vascular and chronic), postoncologic resections (i.e., radical vulvectomy) or dermatologic disorders. The introduction in recent decades of acellular dermal matrices (ADMs) supporting the repair and restoration of skin functionality represented a significant step toward achieving clean wound repair before performing skin grafts. Hard-to-heal ulcers generally depend on local ischemia and nonadequate vascularization. In this context, one possible innovative approach could be the prevascularization of matrices with vessel-forming cells (inosculation). This paper presents a comparative analysis of the most widely used dermal templates, i.e., Integra® Bilayer Matrix Wound Dressing, PELNAC®, PriMatrix® Dermal Repair Scaffold, Endoform® Natural Dermal Template, and Myriad Matrix®, testing their ability to be colonized by human adult dermal microvascular endothelial cells (ADMECs) and to induce and support angiogenesis in vitro and in vivo. By in vitro studies, we demonstrated that Integra® and PELNAC® possess superior pro-adhesive and pro-angiogenetic properties. Animal models allowed us to demonstrate the ability of preseeded ADMECs on Integra® to promote the engraftment, integration and vascularization of ADMs at the site of application.
RESUMO
Surgical site infection in implant-based breast reconstruction is a complication with variable incidence reported in the literature. Due to potential loss of implant and reconstruction, it can have a strong psychological impact on patients. Background and objectives: This study aimed primarily at analyzing the current status of the surgical site infection (SSI), (type, time of onset, clinical presentation, pathogens and management) in patients who underwent implant-based breast reconstruction at our Breast Unit. Secondarily, we wanted to establish whether introduction of a new, updated evidence-based protocol for infection prevention can reduce SSI in implant-based breast reconstruction. Materials and Methods: A single-center retrospective study was performed primarily to evaluate the incidence and features of SSI after implant-based breast reconstruction from 2007 to 2020. In June 2020, a protocol for prevention of SSI in implant-based breast reconstruction was introduced in clinical practice. Secondarily, a data analysis of all patients who underwent implant-based breast reconstruction in compliance with this protocol was performed after preliminarily assessing its efficacy. Results: 756 women were evaluated after mastectomy and implant-based breast reconstruction for breast cancer. A total of 26 surgical site infections were detected. The annual incidence of SSI decreased over time (range 0-11.76%). Data relating to infections' features, involved pathogens and implemented treatments were obtained. Since the introduction of the protocol, 22 patients have been evaluated, for a total of 29 implants. No early infections occurred. Conclusions: Surgical site infection rates at our Breast Unit are comparable to those reported in the literature. The SSI rates have shown a decreasing trend over the years. No SSI has occurred since the introduction of the prevention protocol for surgical site infection in June 2020.

BACKGROUND: The impact of intrauterine growth restriction (IUGR) on lung function in very preterm children is largely unknown as current evidence is mainly based on studies in children born small for gestational age but not necessarily with IUGR. METHODS: Spirometry, transfer factor of the lung for carbon monoxide (TLco), and lung clearance index (LCI) were cross-sectionally evaluated at 8.0-15.0 years of age in children born <32 weeks of gestation with IUGR (n = 28) and without IUGR (n = 67). Controls born at term (n = 67) were also included. RESULTS: Very preterm children with IUGR had lower mean forced expired volume in the first second (FEV1) z-score than those with normal fetal growth (∆ -0.66, 95% confidence interval (CI) -1.12, -0.19), but not significant differences in LCI (∆ +0.24, 95% CI -0.09, 0.56) and TLco z-score (∆ -0.11, 95% CI -0.44, 0.23). The frequency of bronchopulmonary dysplasia (BPD) in the two groups was, respectively, 43% and 10% (P = 0.003). IUGR was negatively associated with FEV1 (B = -0.66; P = 0.004), but the association lost significance (P = 0.05) when adjusting for BPD. CONCLUSIONS: IUGR has an impact on conducting airways function of very preterm children at school age, with part of this effect being mediated by BPD. Ventilation inhomogeneity and diffusing capacity, instead, were not affected. IMPACT: IUGR does not necessarily imply a low birthweight for gestational age (and vice versa). While a low birthweight is associated with worse respiratory outcomes, the impact of IUGR on lung function in premature children is largely unknown. IUGR affects conducting airways function in school-age children born <32 weeks with IUGR, but not ventilation inhomogeneity and diffusing capacity. The impact of IUGR on FEV1 seems mainly related to the higher risk of BPD in this group.

BACKGROUND: Several different flaps can reconstruct intraoral defects or lower limb deficits after free fibula osteo-cutaneous flap harvesting for jaw reconstructions. However, commonly used options may not be available for various reasons and can be associated with significant morbidity. We hypothesized that flaps supplied by the superficial peroneal nerve accessory artery (SPNAA) could be a viable alternative reconstructive option. METHODS: We describe the SPNAA's anatomy using 20 human cadaveric leg dissections and report eight cases involving SPNAA-based perforator flap reconstructions (six propeller flaps and two free flaps) in a retrospective case series. Patient-specific baseline variables and intraoperative and postoperative outcomes are described. RESULTS: Cadaveric dissection suggests that the location of the SPNAA is reliable but its origin varies, with 40% (Nâ¯=â¯8) of SPNAAs being of type I origin, 20% type II (Nâ¯=â¯4), and 40% (Nâ¯=â¯8) type III in our series. All reconstructions were successful. No intraoperative complications occurred during propeller or free-flap reconstructions. No flap failures occurred. One propeller reconstruction showed distal superficial skin necrosis and one donor site wound dehisced; both were successfully managed conservatively. No other short-term or long-term complications occurred. CONCLUSIONS: Flaps based on SPNAA perforators appear effective, reliable, and safe reconstructive methods for covering fibula osteocutaneous donor site defects and for intraoral reconstructions. Controlled trials are required to compare its effectiveness and safety with other reconstructive methods.

Surgical treatment of ear carcinomas needs the selection of the appropriate reconstructive techniques, which depends on the location and the dimensions of the defect after excision of the cancer and the quality of blood supply to the peri-lesional skin. The aim of this study was to evaluate the efficacy and reliability of a new axial island retroauricular flap (middle-retroauricular island flap M-RIF) for coverage of non-helical ear defects with direct donor site closure. METHODS: All patients, from January 2013 to January 2020, with skin tumors of the non-helix region and undergoing a combined skin-cartilage excision with M-RIF local flap reconstruction under local anesthesia, were enrolled in the study. RESULTS: 18 patients (14 men and 4 women) underwent auricle skin-cartilage excision and M-RIF flap reconstruction. The mean age was 65 years (range, 60-85); the type of primary lesions were 12 BCC and 6 SCC. One flap wound dehiscence and one donor site infection and partial necrosis of the posterior auricular skin occurred; no other complications were recorded. CONCLUSIONS: The M-RIF flap is a valid surgical option when dealing with non-helical defects of the anterior pinna. It allows the reconstruction of the defect of the entire anterior surface of the auricle apart from the helix and the lobe and primary donor site closure.
RESUMO
BACKGROUND: Chest-wall contouring surgery (chest-wall reconstructive surgery) is often the first surgical procedure in female-to-male (FtM) gender reassignment surgery (GRS). The main goal of this procedure is to create an aesthetically pleasing male-like chest contour. No universally accepted algorithm exists for detection of the appropriate surgical technique. Also, there is no tool for objective evaluation of the quality of life and satisfaction of these patients after the operation. METHODS: This study involves a single-center clinical trial assessing the patients who underwent subcutaneous mastectomy in FtM GRS between 2003 and 2019. The selection of patients was based on the new "simplified" algorithm consisting of 2 different surgical techniques: the semicircular and the double-incision with free nipple grafting. The selection was based on 3 criteria: breasts size, breast ptosis, and skin elasticity. The outcomes and complication rates were collected and analyzed. The patients' satisfaction and Quality of Life was assessed with a 5-point Likert scale questionnaire, specifically conceived for FtM patients. The aesthetic evaluation was performed using a 5-point Likert scale dealing with the 5 items featuring as the main goals of GRS. RESULTS: 184 mastectomies were performed in 92 FtM GRS patients. The overall reoperation rate was 11.9%. The patient survey revealed both a high satisfaction rate and a good aesthetic result (4.4/5). CONCLUSIONS: The proposed algorithm facilitates the selection of the most suitable technique for top surgery. The patient satisfaction rate evaluated by the proposed Health-Related Quality of Life questionnaire confirmed the outcomes of the use of the algorithm. Further studies to validate the proposed evaluating tools are needed.
RESUMO
This study evaluates the use of acellular dermal matrix (ADM) in conjunction with negative pressure wound therapy (NPWT) and delayed split-thickness skin graft (STSG) application as an alternative to free tissue transfer for defect coverage of the penile shaft. Five patients with genital lymphedema and one with penile skin deficiency underwent penile shaft reconstruction with a two-stage surgical procedure. The first procedure aimed to the correction of skin defect and to neodermis regeneration through the use of an ADM (Integra®, Integra Lifesciences Corp., Plainsboro, NJ, USA) and NPWT. The second procedure 3 weeks later aimed to the covering of the skin defect with an unmeshed STSG. Both the Integra and skin graft showed completely taking at 7 days postop. No major complications occurred. At 6 months grafts gained sufficient elasticity to allow the sliding of the epidermis over the dermal layer, similarly the physiological penile shaft skin. Our results suggest that combined therapy might be an alternative to free tissue transfer for defect coverage of the penile shaft, leading to a good esthetic result, an optimal shaft coverage and providing adequate extensibility during erections. For best results we advise that in these cases urologists should collaborate with plastic surgeons.

INTRODUCTION: Survivors of extreme prematurity may have disrupted lung development. We hypothesized that the multiple breath washout (MBW) index Scond, which is intended to reflect ventilation inhomogeneity from the conducting airways, could be a sensitive marker of respiratory impairment in this group. METHODS: Spirometry, TLco, and MBW were cross-sectionally evaluated at 8 to 14 years of age in children born at <28 weeks between 2004 and 2010 in Udine, Italy. Age-matched controls born at term were also included. Bronchopulmonary dysplasia (BPD) was defined as oxygen-dependence at 36 weeks postmenstrual age. The limits of normal were the 5th percentile of the reference population (Global Lung Initiative) for spirometry and TLco and the 95th percentile of controls for Lung Clearance Index, Scond, and Sacin from MBW. RESULTS: Results were obtained in 47 extremely preterm children (53% boys, mean ± standard deviation age 11.3 ± 2.0 years, 40% with BPD) and 60 controls (50% boys, 11.6 ± 1.9 years). There were significant differences between preterm children and controls in all lung function outcomes, except for Sacin. Among children born <28 weeks, Scond tended to be frequently abnormal than FEV1 z-score (29% vs 14%, P = .06). At multivariable linear regression, in the preterm group, current asthma was significantly associated with a higher Scond (B = 0.019, 95% confidence interval, 0.000-0.038), whereas BPD was not. CONCLUSION: Almost a third of extremely preterm children at school age showed Scond alterations that affected also children without BPD. Longitudinal studies should clarify the prognostic meaning of Scond abnormalities in this group.

Damage to the weightbearing surface of the foot is a challenge for the reconstructive surgeon. The aim is to reconstruct the skeletal tripod and soft tissue, allowing the patient to walk normally. We report the case of a patient admitted with an acute right foot open fracture of the second, third, fourth, and fifth metatarsal bones. After debridement of all nonvital tissues, the patient required reconstruction of the metatarsal heads (third, fourth, and fifth) plus soft tissue coverage. We then performed a reconstruction with a free osteocutaneous fibular flap, insetting the bone perpendicular to the long axis of the metatarsal bones. This configuration allowed the reconstruction of the foot skeletal tripod. A second free flap, a thin radial forearm flap, was added during the revision surgery to improve the venous drainage of the skin paddle of the fibular flap and avoid tension after skin closure. At 1-year follow-up, the patient was able to walk entirely weightbearing on the forefoot, returning to her previous employment with no limitation in physical and recreational activities. To our knowledge, this is the first description of the use of a chimeric osteocutaneous fibular flap, oriented transversely, to reconstruct a complex bone/soft tissue defect after a traumatic loss of multiple metatarsal heads.

BACKGROUND: The nose is a functionally complex organ with also a critical role in aesthetics. For reconstruction of full thickness nasal defects, multiple stages are needed and there is risk for resorption resulting in residual deformity. The aim of this report was to develop and evaluate a new method for full thickness total/subtotal nose reconstruction using the medial femoral condyle free flap (MFCFF) in combination with a paramedian forehead flap. METHODS: Between November 2015 and January 2018, eight patients (four males, four females) mean age 52 years (range 40-73 years) undergoing a total/subtotal nasal excision and subsequential reconstruction with MFCFF plus paramedian forehead flap were enrolled. Six cases were squamous cell carcinomas while two were basal cell carcinomas. The MFCFF was stabilized, with the periosteum as inner layer, with plates and a paramedian forehead flap was used as external skin coverage. All patients were evaluated for with postoperative nasal endoscopy and CT scan. A postoperative questionnaire was given 6 months after surgery. RESULTS: The mean MFCFF size was 2-3.8 cm × 2.25-2.5 cm with a mean pedicle length of 6.3 cm (range 4.1-9.4 cm). The postoperative period was uneventful. The mean follow-up was 16 months, no bone displacement or resorption was observed at the CT scan, no evidence of nasal stenosis occurred. All patients had a satisfying aesthetic evaluation and a good subjective nasal function. CONCLUSIONS: In this series, the MFCFF in combination with the paramedian forehead flap appeared to provide a valid subtotal nose reconstruction, allowing for the recreation of all the three nasal layers and maintaining the nose projection and airway patency in the long term.

INTRODUCTION: The anterolateral thigh (ALT) flap is considered a workhorse reconstructive option; however, it is encumbered by its bulkiness that can result in poor final outcome and need for revision surgery. The aim of the present study was to compare the standard cutaneous ALT free flap and sandwich fascial ALT (SALT) free flap, raised harvesting between the Scarpa's fascia and the crural fascia, for distal extremity soft tissue reconstruction, including pre- intra- and post-operative considerations and outcomes. PATIENTS AND METHODS: A retrospective review of medical records from 2013 to 2018 of 24 patients who underwent distal extremity reconstruction with standard fascio-cutaneous ALT flap (13 patients) and SALT flap (11 patients) was performed. The mean defect dimensions were 12 × 6.5 cm in group 1 and 12 × 6 in group 2. Surgical outcomes and quality of life were assessed (through the upper extremity functional scale and the lower extremity functional scale questionnaires. RESULTS: The mean flap dimensions were 13.1 × 7.1 in group 1 and 14.1 × 7.8 in group 2, the overall flap success rate was 100% (one microvascular venous thrombosis occurred in group 1), no statistically significant difference was recorded regarding microvascular thrombosis (one patient in group p = .369) and infections (one patient in group 1, p = .36) while a statistically significant difference was presence regarding the number of secondary/debulking procedures (6 patients vs. 0) (p = .0076) and the quality of life perception showed an overall better perception in group 2 with statistical significant difference (p = .03). CONCLUSION: The SALT flap represents a valid option, as showed through our preliminary data, when a thin and robust reconstruction is required when dealing with distal extremities soft tissue reconstruction.
