RESUMO

INTRODUCTION: Thigh reconstruction after oncological resection represents a challenge in terms of ideal morphological and functional outcomes to aim for. Very few papers presented a comprehensive approach to this topic, most of them being only small cases series. The purpose of this article was to review our institutional experience in the field of thigh soft-tissue reconstruction, proposing an algorithm to choose the most convenient pedicled or free flap approach according to the different clinical scenarios and the specific morpho-functional requirements of the case. PATIENTS AND METHODS: The authors retrospectively reviewed patients who received flap reconstruction for thigh soft-tissue defects after oncological resection between 2014 and 2021. Demographic and operative data were recorded. Twelve months post-operatively, patients were asked to rate the esthetic and functional outcomes of the reconstructive procedure on a 5-point Likert scale. Additionally, for patients receiving a free functional muscle transfer to restore quadriceps or hamstring function, recovery was evaluated with the Medical Research Council Scale for Muscle Strength. RESULTS: Seventy flap reconstructions of the thigh were, respectively, performed after sarcoma (n = 43), melanoma (n = 13) and non-melanoma skin cancer (n = 14) resection. Pedicled flaps were used in 55 patients: 46 perforator flaps (32 ALT, 4 AMT, 4 PAP, 2 TFL, 2 MSAP, 2 DIEP) and 9 muscle or myocutaneous flaps (4 medial gastrocnemius, 2 gracilis, and 3 VRAM). Microsurgical reconstruction was performed in 15 patients for extensive defects (2 SCIP, 1 latissimus dorsi-LD, 1 thoracodorsal artery perforator-TDAP, 1 ALT, 2 DIEP flaps) or when >50% of the quadriceps or hamstring compartments were resected (eight free functional muscle transfer including five vastus lateralis, two LD, and one rectus femoris). Extensive defect surface, previous irradiation and neoadjuvant chemotherapy appeared to be predictors of free flap reconstruction. Complication (49% vs. 26.6%; p > .05) and readmission rates (32.7% vs. 13.3%; p > .05) were comparable between pedicled and free flap groups, as well as complications severity scores according to Clavien-Dindo classification (1.15 vs. 1.29; p > .05). However, patients with previous irradiation experienced worse outcomes when receiving pedicled rather than free flaps in terms of reintervention (87.5% vs. 28.6%; p = .04) and readmission rates (87.5% vs. 14.29%; p = .01), and severity of surgical complications. Overall patients' satisfaction was high, with esthetic and functional mean score of 4.31 and 4.12, respectively (p > .05). In the FFMT group, M5, M4, M3, and M2 strength was observed in 3, 3, 1, and 1 patients, respectively. CONCLUSION: Oncological thigh defects are usually well addressed with pedicled perforator flaps. Microsurgical reconstruction offers reliable and reproducible results in extensive defects and in previously irradiated fields or when functional restoration is indicated.

RESUMO

The COVID-19 disease has dramatically changed lives worldwide, including education. This is a challenge for traditional learning. In fact, the European Higher Education Area poses the challenge of boosting the quality of teaching through active methodologies supported by digital pedagogy. Gamification is one of these tools and it has considerable attention in the healthcare literature. We aimed to create a game in the Campus Bio-Medico University Hospital Foundation in order to offer continuing education on Quality and Clinical Risk procedures to our staff. The 2021 "Campus Game" (178 players) introduced the "Badge Challenge" (Team Building, Procedures, and Security) and 73 questions. The leaderboard of every single match was posted in some of the hospital's strategic areas and also published online on the company intranet to ensure engagement and competitiveness. Gamification has spontaneously promoted teamworking and a virtuous process of multiprofessional education. We found that, during the Campus Game, there was a 4.9% increase in access to the intranet page containing information on Quality and Patient Safety and an 8% increase in access to the Hospital Policies and Procedures. In the near future, we wish to expand this game, involving hospitals with similar types of activity and levels of attention to quality and safety issues, and also to enhance the network of partners and the principles of Q&S management itself.

RESUMO

BACKGROUND: The extent of histological organ involvement (HOI) to organs and structures of a retroperitoneal liposarcoma may have prognostic implications. This study investigated incidence, characteristics, and risk association of HOI in these patients. PATIENTS AND METHODS: Data of patients who underwent multivisceral resection for primary liposarcoma (2009-2014) were retrospectively analyzed. HOI was the variable of interest and was classified into four degrees: absent (HOI-0), perivisceral (HOI-1), initial (HOI-2), and advanced (HOI-3). Primary endpoint was overall survival (OS). Secondary endpoint was disease-free survival (DFS). The prognostic value of HOI was adjusted for preoperative treatment and the Sarculator nomogram score. RESULTS: A total of 109 patients were included. HOI-0, HOI-1, HOI-2, and HOI-3 were detected in 9 (8.3%), 11 (10.1%), 43 (39.4%), and 46 (42.2%) patients. Median follow-up was 8.4 years [interquartile range (IQR) 7.2-9.6 years]. There were 68 recurrences and 50 patient deaths observed, resulting in a 10-year OS and DFS of 51.1% [95% confidence interval (CI) 41.9-62.1%] and 34.1% (95% CI 25.2-46.1%), respectively. Clinically relevant HOIs (HOI-2 and HOI-3) were found in 35/45 (77.8%) and 54/64 (84.4%) cases of well- and de-differentiated liposarcomas, respectively. On multivariable survival analysis, patients with HOI-3 had significantly shorter OS (HOI-3 vs HOI-0/HOI-1 HR 2.92; p = 0.012) and DFS (HOI-3 vs HOI-0/HOI-1 HR 2.23; p = 0.045), independently of the nomogram score (OS: HR 2.93; p < 0.001; DFS: HR 1.78; p = 0.003). CONCLUSIONS: Initial and advanced HOIs are frequently detected in both well-differentiated and de-differentiated liposarcomas, supporting that multivisceral resection may be needed. HOI stratifies the risk of patients with primary retroperitoneal liposarcoma.

RESUMO

The development and administration of vaccines against COVID-19 was a key element in the fight against the pandemic, as it protected health systems and helped restore global economies. National implementation plans and vaccination strategies for COVID-19 vaccines ensured the immunization of large segments of the population in the shortest time. However, even before the start of the vaccination campaign, it was clear to decision-makers that the usual methods of vaccination were not suitable. The aim of this report is to share the experience of an Italian teaching hospital in the organisation of spaces and activities of healthcare workers to realise a safe vaccination campaign. An in-depth analysis of how the vaccination campaign was organised could be useful to understand strengths and weaknesses learnt from this experience and plan an effective, efficient, and resilient response to future pandemics right away. The adoption of a systemic clinical risk management (SCRM) could guarantee healthcare organizations a more adequate and resilient response in an ethics of a job well done perspective, allowing them to maintain high patient safety standards regardless of the contingent situation for which safety first should be the motto of a disaster response plan.

RESUMO

During the Covid-19 health emergency, telemedicine was an essential asset through which health systems strengthened their response during the critical phase of the pandemic. According to the post-pandemic economic reform plans of many countries, telemedicine will not be limited to a tool for responding to an emergency condition but it will become a structural resource that will contribute to the reorganization of Healthcare Systems and enable the transfer of part of health care from the hospital to the home-based care. However, scientific evidences have shown that health care delivered through telemedicine can be burdened by numerous ethical and legal issues. Although there is an emerging discussion on patient safety issues related to the use of telemedicine, there is a lack of reseraches specifically designed to investigate patient safety. On the contrary, it would be necessary to determine standards and specific application rules in order to ensure safety. This paper examines the telemedicine-risk profiles and proposes a position statement for clinical risk management to support continuous improvement in the safety of health care delivered through telemedicine.

RESUMO

The COVID-19 emergency has led many health facilities to reorganize themselves in a very short time to meet the urgent needs for intensive, semi-intensive or ordinary care of SARS-CoV-2 patients. In this pandemic, characterized by speed of transmission and severity of respiratory symptoms, care has been affected by the increase in volume and clinical complexity of patients, the sudden and unpredictable staff decrease and the lack of support from family members / caregivers. At the same time, experience in the field has shown how "informal" resources have been activated, which enabled to treat the highest possible number of patients above the real availability of resources. The purpose of this study was to explore the experiences of nurses involved in frontline care (COVID Centers) during the pandemic with a particular focus on professional motivation and on the development of technical-professional and personal skills. A study with a qualitative research design using focus group technique was conducted. Two focus groups were held with nine nurses. Data were analyzed with inductive content analysis. The findings can be summarized in five main categories: professional identity; motivation and sense of mission; development of professional and personal skills; spirituality; person-centered care; uniqueness of the lived experience. These findings shed new light on the correlation between motivation, professional identity and value, sense of duty and sense of belonging to the professional group. Moreover, the experience in the COVID Centers represented a valuable opportunity for participants to rediscover some specific issues related to nursing professional identity and to develop new personal and technical-professional skills in a very short time. Finally, nurses experienced once again how the nurse-patient relationship and basic care are essential to provide effective and excellent care, even and especially for patients in critical conditions. Nurses re-discovered, in a careful body care and basic care, irreplaceable elements to give back to patients, often dying, their own dignity, and all the needed closeness and attention necessary also to compensate the absence of the loved ones. These elements represent a way to concretely and deeply express the ethics of a job well done in nursing.

RESUMO

PURPOSE: Local anesthesia is the most used anesthetic technique for inguinal hernia repair, despite its unpredictability. Selective spinal anesthesia with a short-term local anesthetic guarantees rapid recovery, predictable duration and low incidence of side effects. We tried to assess the efficacy of this neuraxial technique in ambulatory setting. METHODS: One hundred thirty-two ASA I-III, aged > 18 patients scheduled for inguinal hernia repair have been randomized into two groups receiving unilateral spinal anesthesia with 40 mg of hyperbaric prilocaine (group A) or local anesthesia with mepivacaine (group B). PRIMARY ENDPOINT: intraoperative and post-operative NRS. Other outcomes: sensory block onset, need for opiates and deep sedation, surgery duration, and time to discharge. RESULTS: Group A: intraoperative NRS was 0 in 100% of patients; post-operative maximum NRS was > 3 in 12.12% of patients. Group B: mean intraoperative NRS was 4; mean post-operative NRS was 2.5. Spinal anesthesia resulted superior in controlling both intraoperative and post-operative pain (p < 0.00001; p = 0.008). Mean time of the motor block resolution in group A was 98 ± 2 min. Mean time to discharge was not significantly different between groups. Surgical time was significantly different between the two groups (mean time of 37 ± 3.2 min group A; 54 ± 6 min group B-p < 0.00001). CONCLUSION: Spinal anesthesia group patients had significantly less pain than local anesthesia group, both intraoperatively and post-operatively, without differences in time to discharge, incidence of complications and with improvement of surgical time. More randomized controlled trials are needed to confirm this hypothesis. TRIAL REGISTRATION: NCT05136534 . Registered November 29, 2021-Retrospectively registered.

RESUMO

BACKGROUND: Myxofibrosarcoma (MFS) is a rare soft tissue sarcoma with a high recurrence rate and a low risk of distant metastasis. It occurs mainly in the extremities of elderly men. Head and neck MFS is extremely rare. Surgery is the cornerstone of treatment. The role of radiotherapy (RT) and chemotherapy (CHT) on MFS is still debated. CASE PRESENTATION: A 67-year-old Caucasian man presented to our sarcoma referral center (SRC) with a history of MFS of the neck excised with microscopic positive surgical margins in a non-referral center. Staging imaging exams did not reveal distant metastasis. After a multidisciplinary discussion, preoperative RT was administered with a total dose of 50 Gy followed by wide surgical excision. Histological examination was negative for viable tumor cells. No relapse occurred during the 24-month postoperative follow-up. CONCLUSIONS: The case described suggests the importance of planned combined treatments with both RT and surgery for high-grade soft tissue sarcoma. RT seems to be promising within this specific histotype. Close follow-up is advisable in all cases. Further studies are needed to confirm if the observed efficacy of combined treatments results in a prolonged time of disease-free survival and overall survival.

RESUMO

INTRODUCTION: Robotic technologies are being increasingly implemented in healthcare, including urology, and holding promises for improving medicine worldwide. However, these new approaches raise ethical concerns for professionals, patients, researchers and institutions that need to be addressed. The aim of this review was to investigate the existing literature related to bioethical issues associated with robotic surgery in urology, in order to identify current challenges and make preliminary suggestions to ensure an ethical implementation of these technologies. EVIDENCE ACQUISITION: We performed a review of the pertaining literature through a systematic search of two databases (PubMed and Web of Science) in August 2020. EVIDENCE SYNTHESIS: Our search yielded 76 articles for full-text evaluation and 48 articles were included in the narrative review. Several bioethical issues were identified and can be categorized into five main subjects: 1) robotic surgery accessibility (robotic surgery is expensive, and in some health systems may lead to inequality in healthcare access. In more affluent countries the national distribution of several robotic platforms may influence the centralization of robotic surgery, therefore potentially affecting oncological and functional outcomes in low-volume centers); 2) safety (there is a considerable gap between surgical skills and patients' perception of competence, leading to ethical consequences on modern healthcare. Published incidence of adverse events during robotic surgery in large series is between 2% and 15%, which does not significantly differ amongst open or laparoscopic approaches); 3) gender gap (no data about gap differences in accessibility to robotic platforms were retrieved from our search); 4) costs (robotic platforms are expensive but a key reason why hospitals are willing to absorb the high upfront costs is patient demand. It is possible to achieve cost-equivalence between open and robotic prostatectomy if the volume of centers is higher than 10 cases per week); and 5) learning curve (a validated, structured curriculum and accreditation has been created for robotic surgery. This allows acquisition and development of basic and complex robotic skills focusing on patient safety and short learning curve). CONCLUSIONS: Tech-medicine is rapidly moving forward. Robotic approach to urology seems to be accessible in more affluent countries, safe, economically sustainable, and easy to learn with an appropriate learning curve for both sexes. It is mandatory to keep maintaining a critical rational approach with constant control of the available evidence regarding efficacy, efficiency and safety.

RESUMO

The syndemic framework proposed by the 2021-2030 World Health Organization (WHO) action plan for patient safety and the introduction of enabling technologies in health services involve a more effective interpretation of the data to understand causation. Based on the Systemic Theory, this communication proposes the "Systemic Clinical Risk Management" (SCRM) to improve the Quality of Care and Patient Safety. This is a new Clinical Risk Management model capable of developing the ability to observe and synthesize different elements in ways that lead to in-depth interventions to achieve solutions aligned with the sustainable development of health services. In order to avoid uncontrolled decision-making related to the use of enabling technologies, we devised an internal Learning Algorithm Risk Management (LARM) level based on a Bayesian approach. Moreover, according to the ethics of Job Well Done, the SCRM, instead of giving an opinion on events that have already occurred, proposes a bioethical co-working because it suggests the best way to act from a scientific point of view.

RESUMO

BACKGROUND: The COVID-19 pandemic induced a global emergency that overwhelmed most hospitals around the world. Access to hospitals has been restricted to selective oncological and urgent patients to minimize surgeries requiring Intensive Care Unit care. All other kind of non-urgent and benign surgeries have been rescheduled. The burden of oncological and urgent cases on the healthcare system has increased. METHODS: We have been asked to become the referral center for major oncological and urgent urological surgeries, increasing our surgical volume. Through meticulous hospital protocols on PPE, use of nasopharyngeal swabs, controlled hospital access and the prompt management of suspected/positive cases, we were able to perform 31% more urological surgical procedures during the COVID-19 pandemic compared to the same period in 2019. RESULTS: We observed a 72% increase in oncological surgical procedures and 150% in urgent procedures. CONCLUSIONS: Our experience shows how the management of oncological and urgent cases can be maintained during unexpected, global emergencies, such as COVID-19.

RESUMO

BACKGROUND: Extraskeletal myxoid chondrosarcoma (EMC) is a rare soft tissue tumor that typically affects the lower limbs of men between the ages of 50 and 60. EMC of the shoulder is rare with a high risk of local recurrence and distant metastasis. A planned surgical excision in sarcoma referral centers (SRCs) is mandatory to obtain the best outcome. The role of chemotherapy (CHT) and Radiotherapy (RT) on soft tissue chondrosarcoma is still controversial. CASE PRESENTATION: A 47-year-old man presented to our referral center with a history of EMC in the right shoulder excised with microscopic positive surgical margins in a non-referral center. Staging imaging exams did not reveal distant metastasis or residual disease, but during follow-up a local recurrence was detected. After a multidisciplinary discussion, preoperative radiotherapy was administered with a total dose of 50 Gy, and then the patient underwent wide surgical excision. Histological examination was negative for viable tumor cells. No relapse occurred in a 24-months post-operative follow up. CONCLUSIONS: The case here described suggests the importance of patient's management in SRCs. A planned combined treatments with both surgery and RT seems to be the best choice to improve local control. RT seems to be promising within this specific histotype. Further studies are needed to confirm if the observed efficacy of combined treatments reflects in a consistent survival benefit for EMC patients.

RESUMO

In the present study, the protective role of inulin against lipopolysaccharide (LPS)-induced oxidative stress was evaluated on human colonic mucosa using a proteomic approach. Human colonic mucosa and submucosa were sealed between two chambers, with the luminal side facing upwards and overlaid with Krebs (control), LPS or LPS+ inulin IQ solution. The solutions on the submucosal side (undernatants) were collected following 30 min of mucosal exposure. iTRAQ based analysis was used to analyze the total soluble proteomes from human colonic mucosa and submucosa treated with different undernatants. Human colonic muscle strips were exposed to the undernatants to evaluate the response to acetylcholine. Inulin exposure was able to counteract, in human colonic mucosa, the LPS-dependent alteration of some proteins involved in the intestinal contraction (myosin light chain kinase (MLCK), myosin regulatory subunit (MYL)), to reduce the up-regulation of two proteins involved in the radical-mediated oxidative stress (the DNA-apurinic or apyrimidinic site) lyase) APEX1 and the T-complex protein 1 subunit eta (CCT7) and to entail a higher level of some detoxification enzymes (the metallothionein-2 MT2A, the glutathione-S-transferase K GSTk, and two UDP- glucuronosyltransferases UGT2B4, UGT2B17). Inulin exposure was also able to prevent the LPS-dependent intestinal muscle strips contraction impairment and the mucosa glutathione level alterations. Exposure of colonic mucosa to inulin seems to prevent LPS-induced alteration in expression of some key proteins, which promote intestinal motility and inflammation, reducing the radical-mediated oxidative stress.

RESUMO

AIM: We carried out an audit to verify compliance to Surgical Safety Checklist (SSC), as we have become aware that compliance across different teams and by individual surgeons has not been optimal. MATERIAL OF STUDY: 100 SSC records from October-December 2014 and 100 from March-June 2015 were inspected to verify correct . 44 surgeons and 34 scrub nurses were asked to complete a questionnaire to know surgeons' compliance to the different stages of the Checklist and the compliance of each surgical team. 100% of scrub nurse and 73.7% of surgeons completed the questionnaire. RESULTS: All Checklist records were correctly filled out but we could verify that while nurses have a strong commitment to the SSC, the Checklist's implementation is not being actively supported by all surgical team members. DISCUSSION: Many surgeons showed limited awareness of not collaborating during SSC procedure and admitted delegating the responsibility for answering questions to other members of their team. A number of them fell into contradiction answering to various parts of the questionnaire. Consistent with the literature, at our hospital there is a gap between quality of Checklist paper records and correct use of this safety tool. CONCLUSIONS: Thanks to the data we have collected we will improve the way the SSC is used and promote change in the behavior of surgeons. Eighteen surgeons (40.9%) expressed willingness to be involved in a work group to revise the SSC and we hope that their commitment to safety and quality will increase. KEY WORDS: Surgical Safety Checklist, Surgeons commitment.

RESUMO

INTRODUCTION: Inflammatory myofibroblastic tumor (IMT), also known as inflammatory pseudotumor, plasma cell granuloma or inflammatory myofibroblastoma, is characterized histopathologically by myofibroblastic spindle cells with inflammatory cell infiltrates ( plasma cell, lymphocytes and eosinophils). Inflammatory myofibroblastic tumor is tipically seen in children or young adults and is most commonly localized in the lung, but it can occur anywhere in the body. CASE REPORT: We present a case in a young woman with severe acute G.I. bleeding, an uncommon presentation of IMT in adults. The patient was admitted to the emergency department for melena. MRI showed a distal jejunum hypervascular mass. Other exams were negative. Surgical excision was recommended, so the patient underwent surgery with complete removal of the tumoral mass. No adjuvant therapy was employed and the patient is asymptomatic after 6 months of follow-up. DISCUSSION: IMT is an rare lesion that mimics malignancy and is accompanied by various clinical manifestations. The treatment of choice is believed to be complete surgical excision and long term follow up. KEY WORDS: Anemia, Inflammatory myofibroblastic tumor (IMT), Small intestine, Surgery.

RESUMO

BACKGROUND: Fructans, such as inulin, are dietary fibers which stimulate gastro-intestinal (GI) function acting as prebiotics. Lipopolysaccharide (LPS) impairs GI motility, through production of reactive oxygen species. The antioxidant activity of various fructans was tested and the protective effect of inulin on colonic smooth muscle cell (SMC) impairment, induced by exposure of human mucosa to LPS, was assessed in an ex vivo experimental model. METHODS: The antioxidant capacity of fructans was measured in an in vitro system that simulates cooking and digestion processes. Human colonic mucosa and submucosa, obtained from disease-free margins of resected segments for cancer, were sealed between two chambers, with the mucosal side facing upwards with Krebs solution with or without purified LPS from a pathogenic strain of Escherichia coli (O111:B4) and inulin (Frutafit IQ), and the submucosal side facing downwards into Krebs solution. The solutions on the submucosal side were collected following mucosal exposure to Krebs in the absence (N-undernatant) or presence of LPS (LPS-undernatant) or LPS+inulin (LPS+INU-undernatant). Undernatants were tested for their antioxidant activity and the effects on SMCs contractility. Inulin protective effects on mucosa and submucosa layers were assessed measuring the protein oxidation level in the experimental conditions analyzed. RESULTS: Antioxidant activity of inulin, which was significantly higher compared to simple sugars, remained unaltered despite cooking and digestion processes. Inulin protected the mucosal and submucosal layers against protein oxidation. Following exposure to LPS-undernatant, a significant decrease in maximal acetylcholine (Ach)-induced contraction was observed when compared to the contraction induced in cells incubated with the N-undernatant (4±1% vs 25±5% respectively, P<0.005) and this effect was completely prevented by pre-incubation of LPS with Inulin (35±5%). CONCLUSIONS: Inulin protects the human colon mucosa from LPS-induced damage and this effect appears to be related to the protective effect of inulin against LPS-induced oxidative stress.

RESUMO

BACKGROUND: The Università Campus Bio-Medico (Italy) promotes a summer volunteering work camp (Workcamp Perù) as a social activity for medical and non-medical students. Some junior doctors participate as 'clinical tutors', together with tutors from other professions; all clinical tutors have some teaching experience in our teaching hospital. CONTEXT: The campsite is located in the South of Peru in the Cañete Valley, an area characterised by extreme poverty and a severe lack of infrastructure. During the five Workcamp Perù trips that have been organised so far, health science students have carried out many activities for disease prevention and health education, and bio-medical engineering students have organised sessions on the safety of electrical installations, for accident prevention. INNOVATION AND IMPLICATIONS: We observed that in this setting tutorial activity is fundamental, because it not only offers students an opportunity to learn but also encourages them to react in a more personal and reflective manner to various stressful situations, which often occur in the work camp. The professional competence of the tutor plays an important role before the work camp, in defining the learning objectives for the students and involving them in training sessions held prior to the work camp. Also, during the camp, tutors work with students and also direct the daily briefing and debriefing sessions that are the most important learning activity. For medical tutors involved in the work camp the volunteering experience is a challenge for developing their specific professional and teaching skills, but it also provides an enriching experience in both professional and personal terms. We consider these work camps to be a useful experience in the training of our clinical tutors.
