Area metropolitana e citta' diffusa: potenzialita' e limiti di un modello urbano
Recenti proposte parlamentari porpongono di mettere fine ad una discussione sulla cittĂ e/o area metropolitana di Roma, confermandone:
• una dimensione d’area vasta coincidente con quella della provincia;
• la sussidiarietà e la sostenibilità come principi ispiratori ed ordinatori dell’azione di governo del territorio;
• le funzioni unitarie e complementari di livello territoriale (programmazione degli interventi per Roma Capitale, le opere di interesse statale, il patrimonio pubblico e privato nazionale ed internazionale, la valorizzazione e la gestione del sistema culturale, ambientale e del turismo, la ricerca e la formazione universitaria, le attività fieristico-congressuali-espositive, l’industria innovativa legata all’ICS);
collocando la questione della scelta metropolitana per Roma ad un livello europeo, eppure intermedio tra la scala politica propria della città -capitale e i compiti di programmazione e gestione che il nostro ordinamento costituzionale attribuisce alle province (per l’Europa, le NUT 3).
Rispetto a questo obiettivo, Roma non appare in posizione soddisfacente nella mappatura europea delle aree/città capitali metropolitane. Anche se, la spinta al policentrismo impressa dall’Unione potrebbe trovare già una base di corrispondenze nell’organizzazione – soprattutto spontanea - del territorio e dell’economia romana (non solo della Città ).
Se per un verso, dunque, c’è da augurarsi che attraverso un più stretto recepimento delle indicazioni europee (Cfr. strutture già cooperative su base policentrica), l’area vasta romana, cioè la provincia, diventi nel prossimo periodo 2007-2013 molto più visibile; la mancanza di strumenti appropriati al raggiungimento di questo obiettivo rappresenta un freno alla piena realizzazione di una metropoli diversa dalla semplice somma di progetti ed impostazioni negoziati “dall’alto”, di portata nazionale e regionale, che escludono, ad una lettura “fisica e formale” del territorio, la domanda di integrazione “dal basso”, cioè il riconoscimento, anche economico, delle forme insediative coese riconoscibili romane.
In tal senso Roma e la sua provincia rappresentano il livello ideale per una lettura della programmazione territoriale europea, ma anche il livello sussidiario della mediazione tra una visione metropoitana globale e una locale, somma di insediamenti continui, diffusi o nucleari isolati (perirubanizzazione mista ad insediamento puntuale), attualmente privi di orientamento alla governance; lontani cioè da quell’insieme di regole con cui si attua la programmazione spaziale e fisica richiesta dall’Unione, entro cui ogni NUT offre il proprio contributo alla creazione di uno spazio integrato, anche attraverso scelte sussidiarie di metropolitanizzazione (cfr. Territorial Agenda 2007)
The Impact of COVID-19 on Plastic Surgery Residency Training
Abstract: Nowadays didactic and surgical activities for residents in the surgery field are less and less due to an increasing burden of documentation and \u201cnon-educational work.\u201d Considering the current lockdown due to the COVID-19 pandemic, it has never been so important to find different ways to allow residents to improve their knowledge. We asked all plastic and esthetic surgery residents in our country to fill out a questionnaire to investigate changes in their didactical activity and analyze problems about their professional growth in the last few months. From the results of such questionnaires, we found that most of the residents feel the decrease in surgical activities during this time is a detrimental factor for their training and that even if all the schools have changed their didactical activities no school has introduced the use of virtual simulators to compensate for the decrease in surgical practice. Actually, the majority of residents use webinars to keep updated, stating that such technologies are useful but not sufficient to analyze plastic surgery topics in depth during COVID-19 lockdown. Virtual interactive tools are well known in different clinical and surgical specialties, and they are considered as a valid support, but it seems that in plastic surgery they are not so used. According to the most recent studies about residents\u2019 didactical program, we have investigated the potential of Anatomage Table in combination with Touch Surgery application as physical and mental aids to bypass the decreased number and kind of surgical interventions performed in this particular time. Anatomage is an academic user-friendly touch screen table; it is used by both medical students and residents to learn human anatomy and to master surgical anatomy. Touch Surgery is an application available on smartphones and tablets that gives the possibility to watch real and virtually designed surgical videos, accompanied by explanatory comments on the surgical phases; they are interactive and give the possibility to check what you have learned through tests administered after virtual classes. In our opinion, these tools represent reliable solutions to improve plastic residents\u2019 training, mostly during the COVID-19 pandemic.

Optimizing aesthetic outcomes after goldilocks mastectomy: A new method of nipple reconstruction
Autologous micrografts and methotrexate in plantar erosive lichen planus: healing and pain control. A case report
Erosive lichen planus is an uncommon variant of lichen planus. We report a case of long-standing and refractory plantar ELPs causing disabling and opiate-resistant pain treated with 'classic' meshed skin graft combined with RigeneraVR micrografts. After approximately 9 months follow-up, no clinical recurrence or pain were observed. Erosive lichen planus (ELP) is an uncommon variant of lichen planus, involving oral cavity and genitalia and, less often plantar areas, where it usually presents with chronic erosions of the soles, along with intense, disabling pain and progressive loss of toenails. An abnormal immune cellular response (CD8+ lymphocytes and macrophages) and the consequent altered production of multiple mediators (interleukin-12, interferon-gamma, tumor necrosis factor-alpha, RANTES and MMP-9), seem to play a crucial role in the pathogenesis, although the etiology remains uncertain. From a histological point of view, ELP shows keratinocyte apoptosis, intense inflammatory response and basal epithelial keratinocytes TNF-alpha overexpression. Several therapies have been proposed, with variable and controversial results. While topical corticosteroids and topical calcineurin inhibitors are the treatments of choice for localized forms, short pulses of systemic glucocorticoids, phototherapy, and systemic immunosuppressants are recommended for generalized cases. Surgery has been reported as a possible therapeutic option in refractory and stable cases with localized lesions, either alone or with cyclosporine. Herein, we report a case of longstanding and refractory plantar ELPS causing disabling and opiate-resistant pain treated with 'classic' meshed skin graft combined with RigeneraVR micrografts
Determinants of surgeon choice in cases of suspected implant rupture following mastectomy or aesthetic breast surgery: Clinical implications
Implant ruptures may be diagnosed by physical examination, ultrasound (US), and magnetic resonance imaging (MRI). The absence of standard guidelines to approach to implant ruptures may cause unnecessary surgical revisions in the absence of radiological confirmation of prosthetic damages.The purpose of this study was to analyze the diagnostic procedures applied to patients with suspected prosthetic rupture and surgeon choices to perform a revision or to plan a clinical and radiological follow-up.We conducted a retrospective study on 62 women submitted to revision surgery due to radiological diagnosis of suspected implant rupture, following mastectomy or aesthetic reconstruction, and admitted to a Plastic Surgery Department between 2008 and 2018.Seventy-three implants, believed to be ruptured, were explanted. One-third of these were intact and unnecessarily explanted. US associated with MRI evaluation resulted in the most helpful diagnostical method.A standardized clinical and radiological approach is essential to manage breast implant ruptures successfully. An innovative protocol is proposed in order to: ensure the appropriate management of implant ruptures and prevent unnecessary surgical revisions; reduce the risk of claims for medical malpractice in cases of unsatisfactory final aesthetic results or worse than before
The Effect of Muscle Exercise on Perforators Flow: A Prospective Cohort Study
Background and objectives: The metabolic response after exercise causes a significant increase in the muscle blood flow. While these effects are demonstrated for intra-muscular vessels, there is no evidence about the inter-muscular vessels, such as the septocutaneous perforators supplying the skin after they branch out from the deep source artery. The aim of our prospective study was to quantify the changes in the anterior tibial artery perforators arterial blood flow after mild isotonic exercise in a young and healthy population. Material and Methods: We performed a prospective analysis of 34 patients who were admitted to the Plastic Surgery Department from December 2019 to April 2020. Flow velocities of two previously identified anterior tibial artery perforators were recorded both before and after 10 complete flexion-extensions of the foot. The time to revert to basal flow was measured. We further classified the overmentioned patients based on their level of physical activity. Results: We registered a significant increase in systolic, diastolic and mean blood flow velocities both in proximal and distal anterior tibial artery perforators after exercise. Fitter patients exhibited a higher increase in proximal leg perforators than those who did less than three aerobic workouts a week. The time to return to basal flow ranged from 60 to 90 s. Conclusions: This was the first study to describe the effect of muscular activity on perforators blood flow. Even mild exercise significantly increases the perforator flow. Waiting at least two minutes at rest before performing the Doppler study, thus avoiding involved muscle activation, can notably improve the reliability of the pre-operative planning

Human Adipose-Derived Stem Cells in Madelung's Disease: Morphological and Functional Characterization
Madelung Disease (MD) is a syndrome characterized by the accumulation of aberrant symmetric adipose tissue deposits. The etiology of this disease is yet to be elucidated, even though the presence of comorbidities, either genetic or environmental, has been reported. For this reason, establishing an in vitro model for MD is considered crucial to get insights into its physiopathology. We previously established a protocol for isolation and culture of stem cells from diseased tissues. Therefore, we isolated human adipose-derived stem cells (ASC) from MD patients and compared these cells with those isolated from healthy subjects in terms of surface phenotype, growth kinetic, adipogenic differentiation potential, and molecular alterations. Moreover, we evaluated the ability of the MD-ASC secretome to affect healthy ASC. The results reported a difference in the growth kinetic and surface markers of MD-ASC compared to healthy ASC but not in adipogenic differentiation. The most commonly described mitochondrial mutations were not observed. Still, MD-ASC secretome was able to shift the healthy ASC phenotype to an MD phenotype. This work provides evidence of the possibility of exploiting a patient-based in vitro model for better understanding MD pathophysiology, possibly favoring the development of novel target therapies
Outcomes in Hybrid Breast Reconstruction: A Systematic Review
Background and Objectives: Lipofilling is a commonly performed procedure worldwide for breast augmentation and correction of breast contour deformities. In breast reconstruction, fat grafting has been used as a single reconstructive technique, as well as in combination with other procedures. The aim of the present study is to systematically review available studies in the literature describing the combination of implant-based breast reconstruction and fat grafting, focusing on safety, complications rate, surgical sessions needed to reach a satisfying reconstruction, and patient-reported outcomes. Materials and Methods: We adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) throughout the whole review protocol. A systematic review of the literature up to April 2022 was performed using Medline, Embase, and Cochrane Library databases. Only studies dealing with implant-based breast reconstruction combined with fat grafting were included. Results: We screened 292 articles by title and abstract. Only 48 articles were assessed for full-text eligibility, and among those, 12 studies were eventually selected. We included a total of 753 breast reconstructions in 585 patients undergoing mastectomy or demolitive breast surgeries other than mastectomy (quadrantectomy, segmentectomy, or lumpectomy) due to breast cancer or genetic predisposition to breast cancer. Overall, the number of complications was 60 (7.9%). The mean volume of fat grafting per breast per session ranged from 59 to 313 mL. The mean number of lipofilling sessions per breast ranged from 1.3 to 3.2. Conclusions: Hybrid breast reconstruction shows similar short-term complications to standard implant-based reconstruction but with the potential to significantly decrease the risk of long-term complications. Moreover, patient satisfaction was achieved with a reasonably low number of lipofilling sessions (1.7 on average)
