Abstract
BACKGROUND AND AIM Androgenetic alopecia (AGA) is a common chronic, hereditary, cutaneous and androgen-dependent condition. Low self-esteem and negatively impact quality of life are often consequences of AGA. Clinical treatment of AGA using SVF (Stromal vascular fraction) has been effective. In fact, hair follicle is affected by various environment factors and one of the most important factors is the vascularity of the scalp which is itself affected bySVF. METHODS During October 2022 we carried out a systematic review to identify all scientific publications discussing about hair loss treatment with stromal vascular fraction or adipose stem cell. We selected 140 articles. After screening process, we kept 9 articles complying with inclusion criteria. Results: No serious adverse events were reported in all studies. Despite standardized protocol was not found, all studies reported a statistically significant increase in the number (density) of hair after SVF treatment. Two studies found a significant improvement at pull test. An increase of hair diameter was noticed after treatment. The combination between medical therapy and SVF proved to be advantageous. CONCLUSIONS SVF is nowadays at the center of studies in the field of regenerative medicine due to its potential applications in many branches of medicine and surgery. The initial results are very promising but furthermore studies are necessary to establish a methodical and systematic research capable of demonstrating its real benefits and the creation of homogenous treatment protocols.

Abstract
BACKGROUND AND AIM The radial forearm free flap (RFFf) and the antero-lateral thigh flap (ALTf) are considered the "key flaps" for oral cavity reconstruction. Nowadays, the literature lacks of an objective and standardized decision-making algorithm for the flap choice. The aim of this study is to describe a decision-making algorithm concerning the more appropriate flap, RFFf or ALTf, in the reconstruction of intra-oral soft tissues based on the volumetric analysis of the defect with a pre-operative Magnetic Resonance Imaging (MRI), updating our previous surgical experience. METHODS We conducted a retrospective observational study including 77 patients who underwent microsurgical reconstruction with RFFf or ALTf after tumor resection of the soft tissues in the oral cavity. During follow-up, patients were evaluated using the UW-QOL questionnaire. RESULTS Analyzing the scores of the UW-QOL questionnaire based on the size of the tumor on preoperative MRI we found that for tumor volume <50cc and between 50-70cc, the patients reconstructed with RFFfobtained statistically significant better scores compared to the ALTf group, while for tumor volume >70cc, the patients reconstructed with ALTf reported statistically significant better scores. CONCLUSIONS Pre-operative RMI-guided volumetric assessment of oral cancer plays a key role in the planning of adequate soft tissue reconstruction and can objectively help surgeons in the correct choice of the flap (RFFf vs. ALTf) for each case based on preoperative tumor size, suggesting for defects <50cc and between 50 and 70 cc a reconstruction with RFFf, while for defects >70cc a reconstruction with ALTf.

Abstract
It was recently shown that the introduction of nanodiamond (ND) into a superconducting metal-organic deposited YBa2Cu3O7-δ (YBCO) film produces an increase in critical current density in self-field conditions (B = 0 T). Such improvement appears to be due to the formation of denser and smoother films than the samples deposited without ND. This paper presents the work done to understand the role of ND during YBCO nucleation and growth. A detailed study on YBCO+ND films quenched at different temperatures of the crystallization process was carried out. Results showed that the reaction responsible for YBCO production appeared effectively affected by ND. In particular, ND stabilizes one of the YBCO precursors, BaF2(1-x)Ox, whose conversion into YBCO requires a prolonged time. Therefore, the YBCO nucleation is slowed down by ND and begins when the experimental conditions favor both thermodynamically and kinetically the formation of YBCO along the c-axis. This effect has important implications because the growth of a highly epitaxial c-axis YBCO film enables excellent superconducting performance.

Abstract
BACKGROUND Greater knowledge of mesenchymal stromal cell (MSC)-based therapies is driving the research into their secretome, identified as the main element responsible for their therapeutic effects. The aim of this study is to characterize the individual variability of the secretome of adipose tissue-derived MSCs (adMSCs) with regard to potential therapeutical applications in neurology. METHODS adMSCs were isolated from the intact adipose tissue of ten subjects undergoing abdominal plastic surgery or reduction mammoplasty. Two commercial lines were also included. We analyzed the expansion rate, production, and secretion of growth factors of interest for neurological applications (VEGF-A, BDNF, PDGF-AA and AA/BB, HGF, NGF, FGF-21, GDNF, IGF-I, IGF-II, EGF and FGF-2). To correlate these characteristics with the biological effects on the cellular targets, we used individual media conditioned with adMSCs from the various donors on primary cultures of neurons/astrocytes and oligodendrocyte precursor cells (OPCs) exposed to noxious stimuli (oxygen-glucose deprivation, OGD) to evaluate their protective and promyelinating properties, using MSC medium as a control group. RESULTS The MSC secretome showed significant individual variability within the considered population with regard to PDGF-AA, PDGF-AB/BB, VEGF-A and BDNF. None of the MSC-derived supernatants affected neuron viability in normoxia, while substantial protection by high BDNF-containing conditioned MSC medium was observed in neuronal cultures exposed to OGD conditions. In OPC cultures, the MSC-derived supernatants protected cells from OGD-induced cell death, also increasing the differentiation in mature oligodendrocytes. Neuroprotection showed a positive correlation with VEGF-A, BDNF and PDGF-AA concentrations in the culture supernatants, and an inverse correlation with HGF, while OPC differentiation following OGD was positively correlated to PDGF-AA concentration. CONCLUSIONS Despite the limited number of adMSC donors, this study showed significant individual variability in the biological properties of interest for neurological applications for adMSC secretome, an under-researched aspect which may represent an important step in the translation of MSC-derived acellular products to clinical practice. We also showed the potential protection capability of MSC conditioned medium on neuronal and oligodendroglial lineages exposed to oxygen-glucose deprivation. These effects are directly correlated to the concentration of specific growth factors, and indicate that the remyelination should be included as a primary target in MSC-based therapies.

Abstract
After the discussion of a straightforward narrative description of the pre-surgical steps required before actual incision in the semi-sitting position1, using vestibular schwannoma surgery as an example, the authors intend likewise to provide a narrative description of the steps following incision, for safe resection of vestibular schwannomas, again attempting to simplify a complex procedure into a more reproducible one. Vestibular schwannoma surgeries are known to be intrinsically related to complications due to their intimate relationship to cranial nerves and vessels as well as brainstem structures in the posterior fossa. It is therefore paramount not only to be familiar with the anatomical and surgical nuances of the procedure, but having an easy-to-follow strategy to significantly reduce complications rate to a minimum. The authors have therefore divided the surgical steps into five major momentums of the procedure, from skin disruption and subcutaneous tissue dissection and retraction, through craniotomy, dural opening, tumor resection with internal acoustic meatus opening, and final closure. Enumeration of the steps, therefore, serve as a facilitated guide for the surgical steps that can be reproduced time and again for better surgical outcomes and the video supplement serves as a useful visual guide for improved understanding of the distinct phases of the surgical intervention.

Abstract
Cervical spondylotic myelopathy (CSM) can be successfully decompressed via either anterior cervical corpectomy and fusion (ACCF) or posterior laminectomy with fusion (LMF). However, few studies have compared the isolated effect of both techniques on cervical sagittal balance, a surrogate end point for clinical outcomes.We aimed to compare the sagittal balance radiological outcomes of ACCF against LMF. A case-matched controlled study of radiological cervical alignment parameters (C0-2, C2-3, index angles, T1 slope, and sagittal vertical axis (SVA)) in two groups of patients was performed by using pre- and postoperative neutral cervical X-rays.In total, 34 patients were enrolled (ACCF n = 17; LMF n = 17). The mean preoperative C2-7 angle was similar (11.58 ± 16.00° for ACCF; 13.36 ± 12.21° for LMF) in both cohorts. Both led to a loss of lordosis (-2.68 ± 13.8°, p = 0.43; -2.94 ± 11.5°, p = 0.31, respectively). At the C0-2, the two operations induced opposite variations (-0.9 ± 8.0°, p = 0.709 for ACCF; 3.5 ± 15.4°, p = 0.357 for LMF). ACCF led to a significant increase in SVA (7.1 ± 11.9 mm, p = 0.002). The C2-3 disk angle more pronouncedly increased with LMF.Both techniques show an equivalent kyphotic effect, with a greater disadvantage for ACCF. The negative impact on SVA changes is greater with ACCF. Both affect the C0-2 unit, with a tendency for kyphosis with ACCF and one for lordosis with LMF. When choosing the appropriate decompression and fusion technique, preoperative sagittal balance parameters should be included in the decision-making process.

Abstract
Cervical spondylosis is the leading cause of cervical myelopathy. When surgery is indicated, it is commonly addressed through an anterior or posterior cervical approach, such as cervical discectomy and fusion (ACDF) or laminectomy and fusion (LMF). Besides their own merits, each one has specific approach- or device-related complications, such as dysphagia, significant postoperative pain, wound infection, adjacent segment degeneration (ASD), and pseudoarthrosis. Through a tissue-sparing minimally invasive technique, posterior cervical fusion (PCF) has shown unfolding compelling evidence of biomechanical stability, good clinical outcomes, and high fusion rates, with fewer complications and better econometrics. On the basis of our own experience, we discuss here the indications, advantages, and drawbacks of minimally invasive PCF.

Abstract
The armamentarium of surgical treatment options for lumbar spondylolisthesis (LS) includes decompression alone, stabilization with interlaminar devices, or instrumented fusion, through open or minimally invasive approaches. Despite its safe profuse use in distinctive lumbar spine disorders, using percutaneous pedicle screws (PPSs) alone to stabilize LS has never been described before. We performed a retrospective study of prospectively collected data, enrolling 24 patients with LS and scrutinizing clinical and radiological outcomes. A statistically significant decrease in visual analog scale (VAS) scores (p < 0.001) and Oswestry Disability Index (ODI) scores (p < 0.001) was observed, as was a reduction in the intake of acetaminophen after surgery (p = 0.022). In the long-term, PPS effectively reduced the index-level range of motion (p < 0.001), reduced preoperative slippage (p = 0.03), and maintained foraminal height, thus accounting for the positive clinical outcomes. It induced a significant segmental kyphotic effect (p < 0.001) that was compensated for by a favorable increase in the pelvic incidence minus lumbar lordosis (PI-LL) index (0.028).

Abstract
Spinal intradural extramedullary (ID-EM) tumors are pathologies widely treated through a classical open approach. However, minimally invasive surgery is gaining traction as a comparable treatment option because it carries less morbidity and may reduce healthcare costs.This study aimed to compare the clinical and functional outcomes of open versus minimally invasive approaches for patients with ID-EM tumors. We performed a retrospective analysis on prospectively collected data from patients with ID-EM tumors submitted to surgery. Baseline features and operative variables were compared, including surgery duration and estimated blood loss (EBL). Postoperative data covered tumor histology, length of stay (LOS), complication(s), and neurological status (Medical Research Council (MRC) scale) at the last follow-up.In total, 46 patients were included: 30 (65.2%) operated through an open approach and 16 (34.8%) through a minimally invasive surgical (MIS) approach. The predominant histology type was schwannomas (43.5%). Lesions more frequently affected the lumbar spine (34.8%). The tumor dimensions were similar in both cohorts. The minimally invasive approach was on average 76.7 min faster and correlated positively with less EBL (140 mL less than that of the open approach). Patients in the MIS group had shorter LOSs (5.63 days vs. 17.27 days) and had fewer postoperative complications. No significant difference in functional outcome was found.MIS is as effective as the traditional approach in achieving comparable functional outcomes, with advantages such as shorter surgery durations, less blood loss, and shorter hospital LOSs.

Abstract
After removal of an infiltrative BCC of the auditory meatus, a soft tissue defect of the temporal-mastoid area with bone exposure, needed reconstruction. Several options have been taken into account and a simple yet effective solution has been found following the spare-parts principle. The ear lobe, preserved during cancer removal, was split and used as a thin skin flap. Adequate coverage of the bone exposure and resurfacing of the external auditory canal was obtained with minimal donor site morbidity and a short surgery in a fragile patient with several comorbidities. The spare-parts strategy can provide successful solution to difficult reconstructive cases regardless of the anatomical area.

Abstract
Objective: Systemic sclerosis is characterized by endothelial dysfunction, autoimmunity abnormalities, and fibrosis of the skin and internal organs. The pathogenetic mechanisms underlying systemic sclerosis vasculopathy are still not clarified. A complex cellular and extracellular network of interactions has been studied, but it is currently unclear what drives the activation of fibroblasts/myofibroblasts and the extracellular matrix deposition. Methods: Using RNA sequencing, the aim of the work was to identify potential functional pathways implied in systemic sclerosis pathogenesis and markers of endothelial dysfunction and fibrosis in systemic sclerosis patients. RNA-sequencing analysis was performed on RNA obtained from biopsies from three systemic sclerosis patients and three healthy controls enrolled in our University Hospital. RNA was used to generate sequencing libraries that were sequenced according to proper transcriptomic analyses. Subsequently, we performed gene set enrichment analysis of differentially expressed genes on the entire list of genes that compose the RNA-sequencing expression matrix. Results: Gene set enrichment analysis revealed that healthy controls were characterized by gene signatures related to stromal stem cells proliferation, cytokine–cytokine receptor interaction, macrophage-enriched metabolic network, whereas systemic sclerosis tissues were enriched in signatures associated with keratinization, cornification, retinoblastoma 1 and tumor suppressor 53 signaling. Conclusion: According to our data, RNA-sequencing and pathway analysis revealed that systemic sclerosis subjects display a discrete pattern of gene expression associated with keratinization, extracellular matrix generation, and negative regulation of angiogenesis and stromal stem cells proliferation. Further analysis on larger numbers of patients is needed; however, our findings provide an interesting framework for the development of biomarkers useful to explore potential future therapeutic approaches.

Abstract
Osteonecrosis of the femoral head (ONFH) is a progressive degenerative disease that ultimately requires a total hip replacement. Mesenchymal stromal/stem cells (MSCs), particularly the ones isolated from bone marrow (BM), could be promising tools to restore bone tissue in ONFH. Here, we established a rabbit model to mimic the pathogenic features of human ONFH and to challenge an autologous MSC-based treatment. ON has been originally induced by the synergic combination of surgery and steroid administration. Autologous BM-MSCs were then implanted in the FH, aiming to restore the damaged tissue. Histological analyses confirmed bone formation in the BM-MSC treated rabbit femurs but not in the controls. In addition, the model also allowed investigations on BM-MSCs isolated before (ON-BM-MSCs) and after (ON+BM-MSCs) ON induction to dissect the impact of ON damage on MSC behavior in an affected microenvironment, accounting for those clinical approaches foreseeing MSCs generally isolated from affected patients. BM-MSCs, isolated before and after ON induction, revealed similar growth rates, immunophenotypic profiles, and differentiation abilities regardless of the ON. Our data support the use of ON+BM-MSCs as a promising autologous therapeutic tool to treat ON, paving the way for a more consolidated use into the clinical settings.

Abstract
Background A good inframammary fold (IMF) definition and position is essential to achieve a satisfactory and natural result in breast surgery. This structure can be damaged, especially during mastectomies. Multiple methods are reported in the literature to restore IMF or improve its definition. In this study, we present the results achieved in a series of patients treated with subdermal liposuction. Methods We report on all our patients who underwent IMF liposuction between January 2016 and June 2020. Subdermal liposuction was performed with a blunt 3 mm cannula along the new IMF to promote skin retraction and adherence between skin and fascia. Results were evaluated subjectively by the patients and objectively by 8 individuals not involved with the treatment. Results We performed IMF liposuction in 88 breasts (69 patients), aged 21–74 (mean 52) years for 82 implant-based reconstructions, 2 tuberous breasts, and 4 contralateral breast augmentations. Mean follow-up was 28 months (6–64). Subjective results: the overall result evaluated with the VAS scale reached 86.6/100. All the 22 patients interviewed judged as well defined the new inframammary fold. Objective results: in 83% of cases the definition of the inframammary fold was judged as good or excellent, while symmetry with contralateral IMF, natural appearance, and overall aesthetic outcome were judged as good. Conclusion Based on our long-term satisfactory results, we recommend the technique of subdermal liposuction to improve the definition of IMF in breast reconstruction after mastectomy and other breast procedures. It is effective, easy to perform, minimally invasive, and durable.

Abstract
Closure of a tracheoesophageal puncture site performed during voice prosthesis implantation may sometimes be required. Besides local techniques, more elaborate procedures, such as closure by means of free microvascular flaps, have been advocated. In this report, we describe a case of local treatment of a hard-to-heal fistula with local application of autologous platelet-rich fibrin matrix in a 77-year-old male patient. At one-week follow-up, the size of the fistula had decreased dramatically but some leakage remained when drinking. After one month, the patient was able to drink and eat normally without any leakage. There was no recurrence of the leakage at two years' follow-up. In summary, local application of platelet-rich fibrin seems to be a simple, safe and effective procedure for tracheoesophageal fistula closure.

Abstract
BACKGROUND Safety of reconstructive microsurgery in elderly patients is still a topic of debate, because no conclusive evidence exists that provides indications and risk evaluation in elderly patients. The purpose of this study, which the Italian Society for Plastic, Reconstructive, and Aesthetic Surgery (SICPRE) has promoted, is to evaluate the safety and the complication risk of elective reconstructive microsurgery in elderly patients as well as to identify patient- or procedure-related risk factors. The secondary aim is to evaluate the predictive role for complications of the Geriatric 8 score (G8). METHODS A total of 194 consecutive patients from 18 centers, aged 65 or older, who received an elective microsurgical flap between April 2018 and April 2019 were prospectively evaluated. Patient-related, treatment-related, and outcomes data were recorded and statistically analyzed through multiple-adjusted logistic regression models. RESULTS Our study showed an increased risk of complications and a longer hospitalization in patients aged ≥75 years with the American Society of Anesthesiologists (ASA) score ≥3 (or G8 score ≤11) as compared to patients >65 years of age and <75 years of age who undergo reconstruction with a microsurgical flap. Instead, flap survival did not significantly vary with age, but was associated only with ASA score ≥3 (or G8 score ≤11) and surgeries that last longer than 480 min; however, flap survival (92.3%) was slightly lower than that commonly reported for in the general population. CONCLUSIONS Reconstructive microsurgery in the elderly is generally safe. The ASA score is easier and quicker than the G8 score and equally useful for risk stratification.

Abstract
The use of plant elicitors for controlling Pseudomonas syringae pv. actinidiae (Psa), the etiological agent of the kiwifruit bacterial canker (KBC), has been analysed in the past and, while salicylic acid (SA) seems to decrease disease susceptibility, methyl jasmonate (MJ) shows an opposite effect. However, the metabolic and genomic responses of Psa-infected plants following elicitation with these two compounds, as compared with non-elicited Psa-inoculated plants, are poorly understood, being the focus of this study. Micropropagated A. chinensis 'Hayward' plants were elicited with MJ or SA, and further inoculated with Psa. Fifteen days post-inoculation, Psa population in MJ-treated plants was increased by 7.4-fold, whereas SA elicitation led to decreased Psa colonization (0.5-fold), as compared with non-elicited inoculated plants. Additionally, elicitation with MJ or SA generally decreased polyphenols and lignin concentrations (by at least 20%) and increased total proteins (by at least 50%). MJ led to the upregulation of SOD, involved in plant antioxidant system, and reporter genes for the jasmonic acid (JA) (JIH and LOX1), abscisic acid (SnRK), SA (ICS1), and ethylene (ACAS1, ETR1 and SAM) pathways. Moreover, it increased ABA (40%) and decreased carotenoids (30%) concentrations. Contrastingly, comparing with non-elicited Psa-inoculated plants, SA application resulted in the downregulation of antioxidant system-related genes (SOD and APX) and of reporter genes for ethylene (ETR1) and JA (JIH and ETR1). This study contributes to the understanding of potential mechanisms involved in kiwifruit plant defences against Psa, highlighting the role of the JA, ABA and ethylene in plant susceptibility to the pathogen.

Abstract
BACKGROUND Reconstruction of complex defects involving nose and close facial units represents an aesthetic and functional challenge. Restoring satisfactory nasal shape, combining aesthetic, nasal function and patent airways is mandatory. In this paper, we describe our approach to total nose defects and we report our 20-year experience in microvascular nose reconstruction.Clinical cases are shown to illustrate different surgical techniques and the evolution of our approach. METHODS Nasal reconstruction procedures were performed on 21 patients between 2000 and 2020 using the radial forearm flap (RFF) or anterolateral thigh (ALT) flap. Reported reconstructions included total/subtotal nasal defects, caused by cancer resections. The key point of our approach is the expanded forehead flap for skin coverage. Reconstruction is completed by cartilage grafts to restore nasal framework and to shape nasal tip. Ancillary procedures were needed in some cases to optimize aesthetic outcomes. RESULTS Twenty-one patients completed the multistage nasal reconstruction. The RFF flap was used in 56% of the cases (n = 11), while the ALT flap was used in 44% (n = 10) of our case series. No difference has been detected in the number of reconstructive stages required to achieve the final result comparing RFF and ALT reconstruction (3.3 vs. 3.1 reconstructive steps). Ancillary procedures were performed in 7 patients. CONCLUSION Microvascular tissue transfer plays a key role in full-thickness nasal defects restoration. Comparing the two groups, both the RFF and ALT are effective and reliable options in lining reconstruction, although with different indications. Expanded forehead flap, combined to free cartilage graft, is our gold standard to provide external skin coverage to rebuild the nasal framework. According to our current approach, accurate preoperative planning, supported by modern technologic tools, multistage reconstruction, and ancillary procedures are useful to accomplish satisfactory functional and aesthetic outcomes.

Abstract
INTRODUCTION Venous congestion is the most common vascular complication of the deep inferior epigastric artery perforator (DIEP) flaps. Adding a second venous drainage by anastomosing a flap vein and a recipient vein (super-drainage) is considered the solution of choice. Evidence to support this procedure, had not yet been confirmed by an analysis of the literature. We aimed to provide this evidence. MATERIALS AND METHODS We searched the literature (MedLine, Scopus, EMBASE, Cochrane Library, and Google Scholar), for studies discussing venous congestion and venous super-drainage in DIEP flap for breast reconstruction. Thirteen of the 35 articles compared results between one or two venous anastomoses. Meta-analysis was performed following PRISMA guidelines. Pooled risk ratio (RRs) for congestion, fat necrosis, partial necrosis, and total necrosis with corresponding 95% confidence intervals (CI) were calculated using a fixed-effect model with the Mantel-Haenszel method. The need to return to surgery (95% CI) was estimated with a random effect model using the DerSimonian and Liard method. RESULTS We showed a statistically significant advantage of super-drainage to reduce the venous congestion of the flap (RR: 0.12, 95% CI: 0.04-0.34, p-value <.001), partial flap necrosis (RR: 0.50, 95% CI: 0.30-0.84, p-value .008), total flap necrosis (RR: 0.31, 95% CI: 0.11-0.85, p-value .023), and the need to take the patient back to surgery for perfusion-related complications (RR: 0.45, 95% CI: 0.21-0.99, p value .048). CONCLUSIONS Performing a second venous anastomosis between the SIEV and a recipient vein (venous superdrainage) reduces venous congestion and related complications in DIEP flaps for breast reconstruction.

Abstract
BACKGROUND Venous congestion is the most common perfusion-related complication of deep inferior epigastric artery perforator (DIEP) flap. Several hydraulic constructs can be created for venous superdrainage in case of flap venous engorgement or as a preventive measure. These can be classified based on the choice of the draining vein of the flap, either a second deep inferior epigastric vein (DIEV) or a superficial inferior epigastric vein (SIEV), and of the recipient vein, either a vein of the chest or the DIEV. METHODS We conducted a comprehensive systematic literature review in Medline, Scopus, EMBASE, Cochrane Library, and Google Scholar to find publications that reported on venous congestion in DIEP flap. The keywords used were DIEP Flap, breast reconstruction, venous congestion, supercharging, superdrainage, SIEV, and DIEV. RESULTS Based on the studies found in the literature, we developed an algorithm to guide the surgeon's decision when choosing the veins for the superdrainage anastomosis. CONCLUSION Several alternatives for venous anastomosis in superdrainage are available. We propose an algorithm to simplify the choice. The use of the ipsilateral SIEV to be connected to a vein of the chest appears to be advantageous. The anatomical position that allows the easiest anastomosis dictates which chest vein to favor.

Abstract
Propeller flaps are local flaps based either on a subcutaneous pedicle, a single perforator, or vessels entering the flap in such a way so as to allow the flap to rotate on their axis. Depending on the kind of pedicle and the anatomical area, the preoperative investigation and the harvesting techniques may vary. An adequate knowledge of skin and subcutaneous tissue perfusion in the different areas of the body is very important to plan a propeller flap to be successful. The surgeon should begin by finding the most suitable perforators in the area surrounding the defect using available technology. The position, size, and shape of the flap are planned about this point. For perforator-pedicled propeller flaps, the procedure starts with an exploration from the margins of the defect or through a dedicated incision to visualize any perforators in the surroundings. The most suitable perforator is selected and isolated, the skin island is replanned, and the flap is harvested and rotated into the defect. The variations in surgical technique for other types of propellers and in specific anatomical areas are also described. Compared with free flaps, propeller flaps have the advantage of a simpler, shorter operation, without the need for a recipient vessel for microanastomosis. Yet, from a technical point of view, an adequate experience in dissecting perforators and the use of magnifying glasses are almost always required.

Abstract
The term propeller flap was introduced for the first time by Hyakusoku to define an island flap, based on a subcutaneous pedicle hub, that was rotated 90 degrees to correct scar contractures due to burns. With the popularization of perforator flaps, the propeller movement was applied for the first time to a skin island vascularized only by an isolated perforator, and the terms propeller and perforator flap were used together. Thereafter, the surgical technique of propeller flaps evolved and new applications developed. With the "Tokyo consensus," we proposed a definition and a classification schema for propeller flaps. A propeller flap was defined as an "island flap that reaches the recipient site through an axial rotation." The classification included the SPP (SPP) flap, the perforator pedicled propeller (PPP) flap, and the supercharged PPP (SCP) flap. A recent update added a new category, the axial pedicled propeller (APP) flap. Here we propose our updated and comprehensive classification of propeller flaps, taking into account the previous classification and subsequent publications. Based on their vascular pedicle, we consider the following five types of propellers: (1) SPP flap, 2.PPP flap, its subtype (2a) SCP flap, (3) APP flap, (4) muscle propeller flap, and (5) chimeric propeller flap. The variables that can be taken into account in the classification are as follows: type of nourishing pedicle, degrees of skin island rotation, position of the nourishing pedicle, artery of origin of the pedicle, and flap shape.

Abstract
The Covid 19 epidemic has modified the way that plastic surgeons can treat their patients. At our hospital all elective surgery was canceled and only the more severe cases were admitted. The outpatient department activity has been reduced also. We present the number and diagnoses of patients, treated as in- and out-patients, during seven weeks from the onset of the epidemic, comparing our activity from the lockdown of elective surgery with the numbers and diagnoses observed during the same weeks of last year. Finally we underline the importance of using telemedicine and web-based tools to transmit images of lesions that need the surgeon's evaluation, and can be used by the patient to keep in touch with a doctor during the distressing time of delay of the expected procedure.

Abstract
Background Multicomponent defects of the head and neck involving the cervical skin pose a reconstructive challenge for microsurgeons and usually requires two flaps. However, many patients who undergo such surgical treatment had prior treatment with radiotherapy and the availability of recipient vessels for free flap reconstruction may be limited. The purpose of this study was to review our experience in the reconstruction of these extensive head and neck defects using a single ALT free flap. Methods A total of 21 patients with complex defects of the head and neck involving multiple anatomical subunits, including the overlying cervical skin, underwent reconstruction with a single ALT flap. The clinical, functional, and aesthetic outcomes of these patients were reviewed. Results The mean hospital stay was 24 days. There was one total flap loss due to pedicle thrombosis. The patient underwent a further ALT reconstruction with no postoperative complications. Cervical fistulas occurred in three patients, and all fistulas were healed by simple wound packing. Three patients with tracheal defect had a functional tracheostoma with adequate stomal patency. A modified barium swallowing study was performed on each patient, and all of them achieved total oral intake. Among them, two patients tolerated only a pureed diet. Conclusions Complex neck reconstruction can be accomplished with a single ALT flap with good clinical and functional results, minimal morbidity and quick recovery.

Abstract
BACKGROUND The acquisition of signed informed consent is not always enough to ensure adequate medical protection. Particularly, in plastic surgery, improving the doctor-patient relationship by understanding the patient's emotions and expectations becomes a determining factor when choosing the best therapeutic strategy for the subject in question, which may also include nonsurgical eligibility. METHODS Ninety patients with various plastic surgery disabilities were recruited and randomly divided into three groups: Patients in the first group underwent the ``traditional'' clinical interview, those in the second underwent the clinical approach called Shared Decision Making (SDM), and those in the third group received both the SDM and a questionnaire evaluating patient expectations (Expectation Questionnaire-Pgm). At the end of each interview, a specialist physician in Plastic, Reconstructive and Aesthetic Surgery was asked to fill in a questionnaire regarding his/her satisfaction with the method used. Likewise, the patient filled in a questionnaire on his/her satisfaction with the interview. RESULTS For the doctors, the third method was superior in investigating patient expectations, emotions, and personal preferences. For the patients, the third method scored significantly higher than the first one for overall satisfaction and ability to evaluate personal preferences and needs and higher than the first and second methods in assessing expectations. CONCLUSIONS For doctors, the SDM coupled with the Expectation Questionnaire-Pgm proved to be the most useful tool to understand patient expectations and emotions and thus improve the medical-patient relationship through shared decision-making. The third method therefore aims for better patient coverage and improved informed consent, thereby reducing the likelihood of litigation and better assessing nonfitness for operation.

Abstract
Albuminuria affects millions of people, and is an independent risk factor for kidney failure, cardiovascular morbidity and death. The key cell that prevents albuminuria is the terminally differentiated glomerular podocyte. Here we report the evolutionary importance of the enzyme Glycogen Synthase Kinase 3 (GSK3) for maintaining podocyte function in mice and the equivalent nephrocyte cell in Drosophila. Developmental deletion of both GSK3 isoforms (α and β) in murine podocytes causes late neonatal death associated with massive albuminuria and renal failure. Similarly, silencing GSK3 in nephrocytes is developmentally lethal for this cell. Mature genetic or pharmacological podocyte/nephrocyte GSK3 inhibition is also detrimental; producing albuminuric kidney disease in mice and nephrocyte depletion in Drosophila. Mechanistically, GSK3 loss causes differentiated podocytes to re-enter the cell cycle and undergo mitotic catastrophe, modulated via the Hippo pathway but independent of Wnt-β-catenin. This work clearly identifies GSK3 as a critical regulator of podocyte and hence kidney function.

Abstract
Introduction Eyelid malignant melanoma represents less than 1 % of all skin melanomas and approximately 1 % of all malignant neoplasms of the eyelid skin. Because of its relative rarity, there is a paucity of descriptive papers reporting only small series of reconstructed patients. The repair of eyelid defects represents a reconstructive challenge. Ideally, the reconstruction of the defect must guarantee function with tissue of the same color, texture, and thickness of that of the removed skin and at the same time avoid complications such as ectropion and lagophthalmos. Materials and Methods We describe a consecutive series of 11 patients affected by cutaneous melanoma of the lower lid who underwent full-thickness excision of the neoplasm and subsequent wide excision. All the patients were treated in one-stage reconstruction modality with a modified monopedicle myocutaneous flap, harvested from omolateral upper eyelid, tunneled under the lateral canthus skin and armed with a conchal auricular cartilage framework. Four patients underwent the sentinel lymph node biopsy during reconstructive procedure. No major complications were reported. In our experience, the proposed myocutaneous flap allows to obtain excellent results, both aesthetically and functionally. Conclusions This technique has the advantage of avoiding multi-staged procedures, with respect for the oncological excision indication for head and neck melanoma, decreasing the incidence of associated major complications.

Abstract
OBJECTIVES A relatively neglected aspect of cleft lip nasal deformity is the effect of septal deviation and inferior turbinate hypertrophy (ITH) on the functional airway. In particular, ITH in the noncleft side can be especially problematic, because it reduces the healthy nasal area, creating bilateral nasal obstruction that might affect the growth of the maxillofacial skeleton. Although these anatomic and functional changes are documented, few recommendations have been developed regarding the proper approach to ITH. The aim of the present study was to asses the ITH severity and determine the degree of nasal airway patency in patients who have undergone primary correction of the nasal septum during lip repair compared to patients operated on without primary septal correction. METHODS The study population included two groups. One group consisted of twenty unilateral cleft lip palate UCLP patients who have previously undergone primary rhinoseptoplasty as part of their treatment plan. The control group consisted of twenty UCLP patients operated on without rhinoseptal correction. The Nasal Obstructive Symptom Evaluation (NOSE) scale and nasal endoscopy were used to assess nasal obstruction. RESULTS The overall untreated group reported severe symptoms across all NOSE scale dimensions more frequently than children who have undergone primary rhinoseptoplasty. The difference was statistically significant for each dimensions (p < 0.05). The mean NOSE score for group A and group B was 21.4 ± 9.4 and 70.8 ± 17.2 respectively (p < 0.0001). In group A turbinate size decreased significantly (p < 0.05) compared to pre-operative data. Comparing the two groups a statistically significant difference in turbinate size was observed (p < 0.0001). CONCLUSION The results of the present study confirm that there is a significant degree of ITH and nasal airway dysfunction in patients with UCLP. Early septal repositioning during primary cleft lip repair results in a statistically significant reduction in IT size and improvement of nasal patency.

Abstract
Aims and background High ferritin serum levels have been reported in patients suffering from various malignancies. The aim of this study was to evaluate the role of ferritinemia in the preoperative diagnosis of ovarian carcinoma. Methods Between March 1993 and September 1996, 60 patients suffering from ovarian carcinoma were surgically treated at our Department. Their ferritin serum levels were measured preoperatively by a solid-phase, two-site chemiluminescent immunometric assay and compared with those of a group of 60 healthy, age-matched, non pregnant controls. Results The mean serum concentration of ferritin was 54.7 ± 7.8 ng/ml (range, 14–135) in healthy controls and 112.3 ± 21.2 ng/ml (range, 9–947) in patients with ovarian carcinoma. The difference was statistically significant (P = 0.005, X2 test = 7.951). Serum ferritin was elevated preoperatively (cutoff ≥ 120 ng/ml) in 18/60 patients with malignancy (sensitivity 30%), whereas the CA 125 levels were above the cutoff in 53/60 patients (sensitivity 88.3%). Only 2/60 women of the control group had ferritin titers > 120 ng/ml (specificity 96.7%). The ferritin levels increased with advancing disease stage; no significant correlation was found between ferritin concentration and neoplastic histology and grading. The mean serum iron levels were also measured preoperatively in patients with ovarian carcinoma and healthy controls. They were 57.2 ± 3.8 and 66.3 ± 2.61 μg/dl, respectively, and the difference was not significant (P = 0.655, X2 test= 0.200). Conclusions The present study underlines that although ferritin shows an elevated specificity, its low sensitivity does not suggest any true usefulness as a tumor marker in epithelial ovarian cancer.

Abstract
The increasing demand for environmental pollution control results in the development and use of new procedures for the determination of dangerous chemicals. Simple screening methods, which can be used directly in the field for a preliminary assessment of soil contamination, seem to be extremely advantageous. In our laboratory, we developed and optimized a rapid test for a preliminary evaluation of both the concentration and the mobility of some potentially toxic metals in soils. This screening test consists of a single extraction of the soil sample with a buffer solution, followed by the titration of the extracted solution with dithizone to determine the contents of bi-valent heavy metals (such as Pb, Cu, Zn, and Cd). This screening method was then directly applied in the field during the sampling campaign in the framework of an Italian-Serbian collaborative project, finalized in the study of metal availability in soils. The results obtained in the field with the rapid test were compared with those obtained in the laboratory following the conventional procedure commonly used to evaluate metal bioavailability (diethylenetriaminepentaacetic extraction). Moreover, selected samples were analyzed sequentially in the laboratory using the standardized BCR three-step sequential extraction procedure. The screening test gave results conceptually in good agreement with those obtained via the BCR procedure. These preliminary data show that the proposed screening test is a reliable method for the preliminary rapid evaluation of metal total concentrations and of potential metal mobility in soils, supporting sampling activities directly in the field.

Abstract
This paper presents a novel poly(dimethylsiloxane) (PDMS) microfluidic immunosensor that integrates a complementary metal-oxide-semiconductor (CMOS) optical detection system for a rapid and highly-sensitive quantification of salivary cortisol. The simple and non-invasive method of saliva sampling provides an interesting alternative to the blood, allowing a fast sampling at short intervals, relevant for many clinical diagnostic applications. The developed approach is based on the covalent immobilization of a coating antibody (Ab), a polyclonal anti-IgG, onto a treated PDMS surface. The coating Ab binds the capture Ab, an IgG specific for cortisol, allowing its correct orientation. Horseradish peroxidase (HRP)-labelled cortisol is added to compete with the cortisol in the sample, for the capture Ab binding sites. The HRP-labelled cortisol, bonded to the capture Ab, is measured through the HRP enzyme and the tetramethylbenzidine (TMB) substrate reaction. The cortisol quantification is performed by colorimetric detection of HRP-labelled cortisol, through optical absorption at 450nm, using a CMOS silicon photodiode as the photodetector. Under the developed optimized conditions presented here, e.g., microfluidic channels geometry, immobilization method and immunoassay conditions, the immunosensor shows a linear range of detection between 0.01-20ng/mL, a limit of detection (LOD) of 18pg/mL and an analysis time of 35min, featuring a great potential for point-of-care applications requiring continuous monitoring of the salivary cortisol levels during a circadian cycle.

Abstract
Sediment is a great indicator for assessing coastal mercury contamination. The objective of this study was to assess the magnitude of mercury pollution in the sediments of the Sagua River, Cuba, where a mercury-cell chlor-alkali plant has operated since the beginning of the 1980s. Surface sediments and a sediment core were collected in the Sagua River and analyzed for mercury using an Advanced Mercury Analyser (LECO AMA-254). Total mercury concentrations ranged from 0.165 to 97 μg g(-1) dry weight surface sediments. Enrichment Factor (EF), Index of Geoaccumulation (Igeo) and Sediment Quality Guidelines were applied to calculate the degrees of sediment contamination. The EF showed the significant role of anthropogenic mercury inputs in sediments of the Sagua River. The result also determined that in all stations downstream from the chlor-alkali plant effluents, the mercury concentrations in the sediments were higher than the Probable Effect Levels value, indicating a high potential for adverse biological effects. The Igeo index indicated that the sediments in the Sagua River are evaluated as heavily polluted to extremely contaminated and should be remediated as a hazardous material. This study could provide the latest benchmark of mercury pollution and prove beneficial to future pollution studies in relation to monitoring works in sediments from tropical rivers and estuaries.

Abstract
Cognitive functioning can be differentially modulated by components of the immune system. Interferon-γ (IFNγ) is a pro-inflammatory cytokine whose production is altered in many conditions displaying some degree of cognitive deficits, although its role in cognitive functioning is still unclear. Here we show that the absence of IFNγ selectively enhances cognitive behaviours in tasks in which the hippocampus is implicated. Moreover, the absence of IFNγ leads to volumetric and cell density changes that are restricted to the dorsal part of the hippocampus. In the dorsal hippocampus, the absence of this pro-inflammatory cytokine leads to an increase in the numbers of newly born neurons in the subgranular zone of the dentate gyrus (DG), an adult neurogenic niche known to support learning and memory, and to an enlargement of the dendritic arborization of DG granule and cornu ammonis (CA)1 pyramidal neurons. Moreover, it also modestly impacts synaptic plasticity, by decreasing the paired-pulse facilitation in the Schaffer collateral to CA1 pyramidal cell synapses. Taken together, our results provide evidence that IFNγ is a negative regulator of hippocampal functioning, as its absence positively impacts on dorsal hippocampus structure, cell density, neuronal morphology and synaptic plasticity. Importantly, these neuroplastic changes are associated with improved performance in learning and memory tasks. Therefore, blockage of the IFNγ signalling may present as promising therapeutic targets for the treatment of inflammation-associated cognitive dysfunction.

Abstract
OBJECTIVE Orofacial clefts (OFCs) are one of the most common birth defects in humans. They are the subject of a number of investigations aimed at elucidating the bases of their complex mode of inheritance involving both genetic and environmental factors. Genes belonging to the folate pathway have been among the most studied. The aim of the investigation was to replicate previous studies reporting evidence of association between polymorphisms of folate related genes and the occurrence of non-syndromic cleft lip with or without cleft palate (NSCL/P), using three independent samples of different ancestry: from Tibet, Bangladesh and Iran, respectively. DESIGN Specifically, the polymorphisms rs1801133 of MTHFR, rs1801198 of TCN2, and rs4920037 of CBS, were tested. RESULTS A decreased risk of NSCL/P was observed in patients presenting the C677T variant at MTHFR gene (relative risk for heterozygotes=0.53; 95% confidence interval [C.I.]=0.32-0.87). The investigated polymorphisms mapping at TCN2 and CBS genes did not provide any evidence of association. CONCLUSION Overall, these results indicate that NSCL/P risk factors differ among populations and confirm the importance of testing putative susceptibility variants in different genetic backgrounds.

Abstract
Photodynamic therapy (PDT) is a relatively new therapy in dermatology that uses the topical application of a porphyrin derivative to selectively destroy a cutaneous target. The action is implemented by the application of a specific light frequency. The ability of porphyrin to selectively target tumor tissue has been known since the 1960s. In the late 1970s, the underlying mechanism was defined, and Dougherty’s discovery of the first chromophore led to the production and commercialization of Photofrin®. Many other chromophores that can act as photosensitizers have been studied since then, with aminolevulinic acid currently the most commonly used chromophore in clinical practice. PDT is simple, minimally invasive and can be administered on an outpatient basis. The efficacy of PDT has been proven for actinic keratosis, Bowen’s disease and basal cell carcinoma; another of its well-known applications is the treatment of photoaging. Indications for its use are continuously increasing, and promising results are reported for various skin diseases. In this paper we report the mechanism of action of PDT with aminolevulinic acid, the literature concerning the most common diseases treated with PDT and the subsequent level of evidence.

Abstract
Many techniques have been described in the literature for the reconstruction of congenital or acquired defects of the earlobe. Most techniques for earlobe reconstruction use adjacent tissue to compose a pedicled or bilobed flap, but usually require a two-stage procedure, or need a skin graft; more rarely reconstructive methods that led to a satisfactory result and a pleasant appearance in one-stage procedure have been described. We describe a personal and geometrical modification of the double-lobed flap according to Gavello's original technique, which allows to shape the anatomical curvature of the earlobe and to reduce the skin retraction without adding any scars or skin graft. In our opinion, the revisited reconstructive technique provides lots of advantages, improves aesthetical results and provides more natural appearance.

Abstract
The paper describes the fieldwork at the Italian test site of the abandoned mine of sphalerite and galena in Ingurtosu (Sardinia), with the aim to assess the applicability of a "toolbox" to establish the optimized techniques for remediation of soils contaminated by mining activities. A preliminary characterization-including (hydro)geochemistry, heavy metal concentration and their mobility in soil, bioprospecting for microbiology and botany-provided a data set for the development of a toolbox to deliver a microbially assisted phytoremediation process. Euphorbia pithyusa was selected as an endemic pioneer plant to be associated with a bacterial consortium, established with ten selected native strains, including metal-tolerant bacteria and producers of plant growth factors. The toolbox was firstly assessed in a greenhouse pot experiment. A positive effect of bacterial inoculum on E. pithyusa germination and total plant survival was observed. E. pithyusa showed to be a well-performing metallophyte species, and only inoculated soil retained a microbial activity with a high functional diversity, expanding metabolic affinity also towards root exudates. These results supported the decision to proceed with a field trial, investigating different treatments used singly or in combination: bioaugmentation with bacterial consortia, mycorrhizal fungi and a commercial mineral amendment. Microbial activity in soil, plant physiological parameters and heavy metal content in plants and in soil were monitored. Five months after the beginning, an early assessment of the toolbox under field conditions was carried out. Despite the cold season (October-March), results suggested the following: (1) the field setup as well as the experimental design proved to be effective; (2) plant survival was satisfactory; (3) soil quality was increased and bioaugmentation improved microbial activity, expanding the metabolic competences towards plant interaction (root exudates); and (4) multivariate analysis supported the data provided that the proposed toolbox can be established and the field trial can be carried forward.

Abstract
In the process of remediation of mine sites, the establishment of a vegetation cover is one of the most important tasks. This study tests two different approaches to manipulate soil properties in order to facilitate plant growth. Mine waste from Ingurtosu, Sardinia, Italy rich in silt, clay, and heavy metals like Cd, Cu, and Zn was used in a series of greenhouse experiments. Bacteria with putative beneficial properties for plant growth were isolated from this substrate, propagated and consortia of ten strains were used to inoculate the substrate. Alternatively, sand and volcanic clay were added. On these treated and untreated soils, seeds of Helianthus annuus, of the native Euphorbia pithyusa, and of the grasses Agrostis capillaris, Deschampsia flexuosa and Festuca rubra were germinated, and the growth of the seedlings was monitored. The added bacteria established well under all experimental conditions and reduced the extractability of most metals. In association with H. annuus, E. pithyusa and D. flexuosa bacteria improved microbial activity and functional diversity of the original soil. Their effect on plant growth, however, was ambiguous and usually negative. The addition of sand and volcanic clay, on the other hand, had a positive effect on all plant species except E. pithyusa. Especially the grasses experienced a significant benefit. The effects of a double treatment with both bacteria and sand and volcanic clay were rather negative. It is concluded that the addition of mechanical support has great potential to boost revegetation of mining sites though it is comparatively expensive. The possibilities offered by the inoculation of bacteria, on the other hand, appear rather limited.

Abstract
Introduction: The anterolateral thigh flap (ALT) is a versatile flap and very useful for the reconstruction of different anatomical districts. The main disadvantage of this flap is the anatomical variability in number and location of perforators. In general, absence of perforators is extremely rare. In literature, it is reported to be from 0.89% to 5.4%. If no sizable perforators are found, an alternative reconstructive strategy must be considered. Tensor fascia lata (TFL) perforator flap can be a good alternative in these cases: Perforator vessels are always present, the anatomy is more constant and it is possible to harvest it through the same surgical access. The skin island of the flap can be very large and can be thinned removing a large part of the muscle allowing its use for almost the same indications of the ALT flap. Materials and Methods: We report 11 cases of reconstruction firstly planned with the ALT flap, then converted into TFL perforator flap. Results and Conclusion: The result was always satisfactory in terms of the donor site morbidity and reconstructive outcome.

Abstract
The surface lipopolysaccharide of gram-negative bacteria is both a virulence factor and a B cell antigen. Antibodies against O-antigen of lipopolysaccharide may confer protection against infection, and O-antigen conjugates have been designed against multiple pathogens. Here, we describe a simplified methodology for extraction and purification of the O-antigen core portion of Salmonella lipopolysaccharide, suitable for large-scale production. Lipopolysaccharide extraction and delipidation are performed by acetic acid hydrolysis of whole bacterial culture and can take place directly in a bioreactor, without previous isolation and inactivation of bacteria. Further O-antigen core purification consists of rapid filtration and precipitation steps, without using enzymes or hazardous chemicals. The process was successfully applied to various Salmonella enterica serovars (Paratyphi A, Typhimurium, and Enteritidis), obtaining good yields of high-quality material, suitable for conjugate vaccine preparations.

Abstract
The treatment of complex wounds often requires multiple surgical debridement and eventually reconstruction with skin grafts or flaps, under local or general anesthesia. When the patient's general conditions contraindicate surgical procedures, topical negative pressure with vacuum assisted closure (VAC)) device can achieve wound healing with reduction of healing time and simpler management. We treated with VAC device four patients with complex wounds and important contraindications to surgery. In all the patients, we used VAC device with common protocol of topical negative pressure. The healing was obtained in a period variable between 18 and 40 days; the results were satisfactory in three cases, one patient developed an aesthetically unpleasant scar. We present our experience to propose VAC when surgical procedures are contraindicated.
