Orbital exenteration is a radical and disfiguring operation. It is still under debate the absence of correlation between the term describing the resulting orbital defect and the type of reconstruction. Authors' goal was to propose a consistent and uniform terminology for Orbital Exenteration surgery in anticipation of patients' tailored management. Twenty-five patients who underwent orbital exenteration between 2014 and 2020 were reviewed. A parallel comprehensive literature review was carried on. Five different types of orbital exenteration where outlined. Multiple reconstructive procedures were enclosed. An algorithm for orbital reconstruction was proposed based on anatomic boundaries restoration. Eyelid removal was first considered as an independent reconstructive factor, and both orbital roof and floor were indicated as independent reconstructive goals, which deserve different defect classification. In our opinion, this algorithm could be a useful tool for patient counseling and treatment selection, which might allow a more tailored patient care protocol.Level III.

The free fibula flap is a reliable approach used to reconstruct maxillofacial osseous defects. Virtual surgical planning facilitates the execution of such segmental bony reconstruction, usually preceding the placement of endosseous implants for dental rehabilitation. Novel advances in digital technology allow for fabrication of 3D guides for implant placement in the fibula bone segments before their fixation to the facial defect, with reduced ischemic time, reduced treatment time, faster dental rehabilitations, and unprecedented improvements in the overall treatment efficiency. This case report illustrates the use of digitally designed 3D-printed surgical plates for a single-stage surgery of free fibula flap with implant placement. The patient was successfully treated and followed over 2 years. Comparison between preoperative virtual planning and postoperative scans revealed a high accuracy of implant and bone segment positioning.

Purpose In head and neck squamous cell carcinoma (HNSCC), the potential mitigating effect of complementary medicine interventions such as acupuncture for radiation-induced toxicity is unknown. This study aimed to assess the impact of acupuncture on the incidence and degree of severity of common radiation-induced side effects. Methods In accordance with pre-specified PICO criteria, a systematic review was performed. Two electronic databases (Medline and Embase) were searched over a 10-year time frame (01/01/10 to 30/09/20). Patients undergoing a curatively intended, radiation-based treatment for histologically confirmed squamous cell carcinoma of the nasopharynx, oropharynx, larynx, hypopharynx and oral cavity represented the target population of our study. Accurate information on the acupuncture methodology was reported. All included articles were evaluated to identify any potential source of bias Results Five papers were included in our qualitative analysis, for a total of 633 subjects. Compliance to per-protocol defined schedule of acupuncture sessions was high, ranging from 82 to 95.9%. Most patients (70.6%) were randomly allocated to receive acupuncture for its potential preventive effect on xerostomia. The large heterogeneity in study settings and clinical outcomes prevented from performing a cumulative quantitative analysis, thus no definitive recommendations can be provided. Conclusions Although shown to be feasible and safe, no firm evidence currently supports the use of acupuncture for the routine management of radiation-induced toxicity in HNSCC.

Alzheimer's disease (AD) includes progressive symptoms spread along a continuum of preclinical and clinical stages. Although numerous studies uncovered the neuro-cognitive changes of AD, very little is known on the natural history of brain lesions and modifications of brain networks in elderly cognitively-healthy memory complainers at risk of AD for carrying pathophysiological biomarkers (amyloidopathy and tauopathy).We analyzed resting-state electroencephalography (EEG) of 318 cognitively-healthy subjective memory complainers from the INSIGHT-preAD cohort at the time of their first visit (M0) and two-years later (M24).Using 18F-florbetapir PET-scanner, subjects were stratified between amyloid negative (A-; n = 230) and positive (A+; n = 88) groups. Differences between A+ and A- were estimated at source-level in each band-power of the EEG spectrum.At M0, we found an increase of theta power in the mid-frontal cortex in A+ compared to A-. No significant association was found between mid-frontal theta and the individuals' cognitive performance. At M24, theta power increased in A+ relative to A- individuals in the posterior cingulate cortex and the pre-cuneus. Alpha band revealed a peculiar decremental trend in posterior brain regions in the A+ relative to the A- group only at M24. Theta power increase over the mid-frontal and mid-posterior cortices suggests an hypoactivation of the default-mode network in the A+ individuals and a non-linear longitudinal progression at M24.We provide the first source-level longitudinal evidence on the impact of brain amyloidosis on the EEG dynamics of a large-scale, monocentric cohort of elderly individuals at-risk for AD.

Carotid cavernous fistulas (CCFs) are abnormal connections between the cavernous sinus (CS) and carotid arteries. In direct CCFs, a transarterial route is often the preferred vascular access; in case of indirect CCFs, the complex anatomy of the feeder vessels and their extra-intracranial anastomosis makes the transarterial embolization challenging and often ineffective. The aim of this study was to review our experience with the transorbital approach to treat patients affected by CCF who have already experienced an endovascular failure procedure, in order to assess this salvage technique feasibility, by analyzing possible risks and complications. We performed a retrospective study of all patients affected by CCFs who underwent transorbital embolization between February 2017 and February 2019 at our institution. All patients (3 cases) tolerated both the retrograde embolization and the direct surgical approach with clinical improvement; the closure of the fistula was complete and verified intraoperatively by angiography. Esthetic result was acceptable in all cases with reduction of the proptosis and the intraocular pressure, and increased visual acuity. There were no complications or clinical recurrence. Transorbital approach for the endovascular treatment of CCFs is a feasible and safe salvage procedure, which can find indication after other endovascular access failures.

Stratospheric long-duration balloons (LDBs) are a cheap and easy way to access the near space, allowing geophysical and cosmological observations.A common issue for LDBs is the high bit rate data transferring. Just few hours after launch balloons are nor reachable with direct radio link, and satellite links are, simply, too expensive. For this reason the satellite link is used only for house keeping and remote control, and scientific data are recorded on board. This makes mandatory to recover the payload to get the observation’s results, a difficult task operating in polar areas, impossible during the polar winter.The aim of the project is to provide an autonomous glider capable of physically carrying data and samples from the stratospheric platform to a recovery point on the ground. The glider itself can also transport instruments and can make measurements during the flight. We estimate that an electrical motorglider released in the stratosphere can fly for several hundreds kilometres.The glider is installed on the balloon payload through a remotely controlled release system (which provides its own direct radio link and satellite communications), and connected to the main computer to receive data and geographic coordinates of the recovery point. The glider trajectory can be monitored with Iridium SBD, and remotely controlled using Iridium too.The glider is a carbon fiber reinforced foam structure, a compact and robust design, self-stable, which has been shown to steer correctly in the lower stratosphere.Several test have been conducted with motorized and non motorized gliders, showing that the presence of the engine helps the aircraft to get into flight attitude, at around 20 km of altitude, compared to 10 km achieved in non-motorized flights.

Alzheimer’s Disease (AD) includes progressive symptoms spread along a continuum of pre-clinical (pre-AD) and clinical stages. Pre-AD refers to cognitively healthy individuals with presence of positive pathophysiological biomarkers of AD (i.e., markers of amyloidopathy and tauopathy). Although numerous studies uncovered the neuro-cognitive changes of AD, very little is known on the natural history of brain lesions and modifications of brain networks of pre-AD. To address this issue, we analysed resting-state EEG data of 318 cognitively healthy individuals with subjective memory complains from the INSIGHT-preAD cohort at the time of their first visit (M0) and two-years later (M24). Using 18F-florbetapir PET-scanner, subjects were stratified between amyloid positive (A-; n=230) and amyloid negative (A+; n=88) groups. Differences between A+ and A- individuals were estimated at source level in each band of the EEG power spectrum. At M0, we found an increase of theta-band power in the mid-frontal cortex in A+ compared to A-. No significant association was found between mid-frontal theta power and the individuals’ cognitive performance. While the very same effect was not replicated at M24, theta-band power increased in A+ relative to A- individuals in the posterior cingulate cortex and the pre-cuneus. Furthermore, alpha band revealed a peculiar decremental trend in posterior brain regions in the A+ relative to the A- group only at M24. These results provide the first source-level longitudinal evidence on the impact of brain amyloidosis on the EEG dynamics of a large-scale, monocentric cohort of pre-AD. Theta-band power increase over the mid-frontal and mid-posterior cortices suggests an hypoactivation of the default-mode network in individuals at-risk of AD and a non-linear longitudinal progression of the AD-spectrum.

Recurrent salivary gland carcinomas (RSCs) are poorly characterized and their clinical features and treatment options have not yet been fully described. The goal of this study was to analyze the therapeutic strategies and oncological outcomes of RSC patients through a literature review analysis. This systematic review was performed according to the PRISMA statements. Inclusion criteria for the systematic review were based on the population, intervention, comparison, and outcomes according to (PICO) framework. Two thousand seven hundred and four records were selected and 1817 recurrences were studied. Three hundred and sixty-five patients underwent salvage surgery (20.1%) and their 5-year mortality rate, overall survival and disease-free survival were 35%, 70%, and 42%, respectively. RSCs are aggressive neoplasms with a high rate of distant metastases (28.9%). Salvage surgery can be considered in patients with limited local and/or regional recurrences, even in case of single distant relapse, appearing within the first 3 years of follow-up.

Although the vaccination of healthcare workers (HCWs) is considered essential for preventing influenza circulation in the hospital setting, vaccination coverage (VC) in this group remains low. Among the reasons cited by HCWs is a lack of time to attend the vaccination clinic. For the 2018/2019 influenza season, active (on-site) influenza vaccination was offered directly in 44 operative units (OUs) of the Bari Policlinico hospital (50 OUs, 3,397 HCWs). At the same time, the hospital granted the HCW access to the vaccination clinic during October and December 2018. VC achieved among HCWs of Bari Policlinico during the 2018/2019 influenza season was then analyzed, and the results compared with those of the 2017/18 season. During the 2018/19 season, VC was 20.4% (n = 798) and thus higher than the 14.2% of the 2017/18 season (+6.2%). The highest VC was among physicians (33.4%), followed by other HCWs (23.8%), auxiliary staff (8.6%), and nurses (7.2%). Overall, 284 (36.5%) HCWs were vaccinated at on-site sessions. Multivariate analysis showed that vaccination uptake was associated with male gender and with work in OU where vaccination was actively offered. On the other hand, being a nurse or auxiliary staff member and working in the surgical area were deterrents. Although VC remained unsatisfactory, active on-site vaccination proved to be an important strategy to improve vaccination compliance, increasing 44% compared to the previous season. Nonetheless, mandatory vaccination directed by public health institutions may be the only way to reach a minimum level of coverage.

The neuromodulation induced by neurofeedback training (NFT) remains a matter of debate. Investigating the modulation of brain activity specifically associated with NF requires controlling for multiple factors, such as reward, performance, congruency between task and targeted brain activity. This can be achieved using sham feedback (FB) control condition, equating all aspects of the experiment but the link between brain activity and FB. We aimed at investigating the modulation of individual alpha EEG activity induced by NFT in a double-blind, randomized, sham-controlled study. Forty-eight healthy participants were assigned to either NF (n = 25) or control (n = 23) group and performed alpha upregulation training (over 12 weeks) with a wearable EEG device. Participants of the NF group received FB based on their individual alpha activity. The control group received the auditory FB of participants of the NF group. An increase of alpha activity across training sessions was observed in the NF group only (p 0.001). This neuromodulation was selective in that there was no evidence for similar effects in the theta (4–8 Hz) and low beta (13–18 Hz) bands. While alpha upregulation was found in the NF group only, psychological outcome variables showed overall increased feeling of control, decreased anxiety level and increased relaxation feeling, without any significant difference between the NF and the control groups. This is interpreted in terms of learning context and placebo effects. Our results pave the way to self-learnt, NF-based neuromodulation with light-weighted, wearable EEG systems.

Since the multicomponent meningococcal B vaccine introduction, the Apulian Regional Health Authority implemented postmarketing surveillance program, as provided by Italian laws.From National Pharmacovigilance Network, we selected 4CMenB AEFIs reported in Apulia from 01 January 2014 to 31 December 2019, while the number of 4 cMen B doses administered per year was obtained from the regional immunization database (GIAVA).For each subject who experienced an adverse event following meningococcal B vaccine (AEFIs), a predefined form was filled in.A total of 214 AEFIs (26.5 × 100.000 doses) were reported after any dose of MenB-4 c vaccination of which 58/214 (27.1%) were classified as serious (7.2 × 100,000 doses), 145/214 (67.8%) as not serious (180 × 100,000 doses), and 11/214 (5.1%) as undefined (1.3 × 100,000 doses).The average age of subjects who experimented and AEFI was 30 months. The majority of serious AEFIs were reported in 2- to 11-month-old children (44/57; 77.2%). A total of 31/58 (3.8 × 100,000 doses; 53.4%) serious AEFIs were reported as having a 'consistent causal association' with vaccination. Of these, fever/hyperpyrexia was reported in 21/31 (2.6 × 100,000 doses; 67.7%); hypotonic-hyporesponsive episode was reported in 7/31 (0.9 × 100,000 doses [add %-age]) and was the most frequent adverse event with neurological symptoms. A total of 13/31 (41.9%) serious AEFIs classified as 'consistent causal association' were reported after the first dose of 4cMenB, of these 5/13 (38.5%) children did not complete the vaccination schedule.Our data seemed to confirm, in a large population, the a good safety profile of the universal mass vaccination with 4CMENB.

Purpose To report a rare case of adenocarcinoma (ADC) arising in the conjunctiva which locally recurred and metastasized to the periparotid lymph nodes. Methods This is a single observational case report. Results A 79-year-old male patient was referred to us for a suspected recurrence of conjunctival carcinoma of the right eye. At presentation, we observed an elevated conjunctival lesion with corneal involvement. He was treated with neoadjuvant mitomycin C 0.04% eye drops, followed by surgical excision of the lesion, cryotherapy of the excision margins, and reconstruction with amniotic membrane graft. The tumor was histologically diagnosed as ADC. The negative systemic evaluation and the immunoprofile led us to believe the primitive nature of the tumor. The excision margins were positive, and the patient was lost to follow up for 7 months, and when he came back, a new local recurrence was diagnosed. Then, he received rescue treatment with mitomycin C 0.04% eye drops with complete regression of the lesion. No local recurrence was observed until the 14-month follow-up visit, during which the patient complained of swelling in the right parotid region. Subsequently, he underwent total parotidectomy with neck dissection. Metastasis was found in 3 periparotid lymph nodes. The patient did not receive further treatments, and no recurrences were observed over the following 20 months. Conclusions ADC arising in the conjunctiva is a very rare occurrence. Additional observation is required for the management of this rare conjunctival tumor.

Background In Italy medical cannabis is a prescription drug since 1998. Even though it could not be considered a therapy as such, it is indicated as a symptomatic treatment also in cancer patients, to cure iatrogenic nausea/vomiting and chronic pain. Patients and methods We conducted a knowledge survey about medical cannabis among cancer patients referred to two outpatient cancer care centers and a home care service. Results From February to April 2018, 232 patient were enrolled; 210 patients were on active disease-oriented treatment (90.5%), while 22 (9.5%) not. Eighty-one percent of the patients have heard about medical cannabis, but only 2% from healthcare professionals. Thirty-four percent of responders thought about using cannabis to treat one or more of their own health problems, especially pain (55%). Despite that, 18% of the participants believe that medical cannabis could have negative effects on their own symptoms. Patients with high educational level better knew cannabis (odds ratio = 3.52; 95% confidence interval: 1.07–11.53), and medical cannabis (odds ratio = 3.21; 95% confidence interval: 1.48–6.98), when compared to patient with low educational level. Patients who were on active disease-oriented treatment better knew medical cannabis (odds ratio = 3.91; 95% confidence interval: 1.26–12.11) compared to “out of treatment” patients. Metastatic patients were less informed about medical cannabis compared to patients on adjuvant treatment. Conclusions Our survey shows that most of Italian cancer patients know medical cannabis and a third of them have considered using cannabis to treat one (or more) of their own health problems. In the same time, they are poorly informed and do not tend to ask for information about medical cannabis to healthcare professionals.

To assess postoperative changes of the upper airway in a pediatric syndromic cranial-synostosis (SCS) population who underwent Le Fort III (LFIII) or frontofacial advancement by distraction osteogenesis (DO). Charts' review of 25 SCS infants presented at our tertiary-care children's hospital between January 2005 and December 2016 was performed. Preoperative (T0) and postoperative (T1) three-dimensional computed tomography (3D-CT) and polysomnography (PSG) were recorded. Differences between T0 and T1 airway volumes and changes in PSG data were analyzed. 18 patients were included. The mean T0 and T1 volumes were calculated as 15.963 mm3 ± 7.181 SD and 24.550 mm3 ± 12.946 SD, respectively. Airway areas increased significantly (p A statistically significant gain of the upper airway after LF III and DO in SCS patients has been demonstrated. Given the absence of a direct relationship between post-operative upper airway volume increase and OSAS degree improvement, further insights should consider performing T0 and T1 sleep endoscopy analysis to complete the diagnostic workup and to better assess the level of residual or recurrent upper airway obstruction in patients who experience unsuccessful surgical treatment.

Since the influenza season 2018/19, the Italian Ministry of Health recommended a dose of cell-based quadrivalent vaccine (Flucelvax Tetra) for HCWs (healthcare workers), because this vaccine seemed more efficacious in the prevention of AH3N2 virus. Due to the lack of pre-registration data, the safety profile of this new vaccine must be investigated in post-marketing surveillance. The aim of our study is to evaluate, through a post-marketing active surveillance program developed during the 2019/20 influenza season, any Adverse Events Following Immunization (AEFIs) that happened in the 7 days after immunization with Flucelvax Tetra. The study was carried out in a sample of HCWs of Policlinico General University-Hospital (Apulia, South Italy). AEFIs were classified as ‘serious’ or ‘not serious’ according to the WHO (World Health Organization) guidelines, the WHO causality assessment algorithm was applied to classify serious AEFIs. A total of 741 HCWs were enrolled, and 430 AEFIs (reporting rate: 58.0 (95%CI: 54.4–61.6) × 100 enrolled) were recorded. Of these, 429 of 430 (99.8%, reporting rate: 57.8 (95%CI: 54.2–61.5) × 100 enrolled) were classified as not serious and one (0.2%, reporting rate: 0.13 (0.03–0.75) × 100 enrolled) was classified as serious. Local reactions were the adverse reaction reported most frequently (88%), regarding the serious AEFI, causality assessment excluded the causal link with the administration of the vaccine. All the AEFIs resolved without sequelae. Flucelvax Tetra showed a profile of high safety. Due to their characteristics of greater sensitivity than passive surveillance, active surveillance programs can be useful in defining the safety profiles of a given vaccine/drug in certain population subgroups.

Background: The management of difficult-to-treat periocular basal cell carcinoma becomes very challenging in cases of delayed diagnosis, leading to the development of locally advanced basal cell carcinoma.Objective: The aim of this study was to evaluate the outcomes of Hedgehog pathway inhibitors (vismodegib and sonidegib) treatment in patients affected by periocular locally advanced basal cell carcinoma. We focused on the common adverse events and their correlation with the administration schedule in order to determine a management protocol specific for the periocular area.Methods: This observational prospective study included a single-center case series with patients who were histologically confirmed to have periocular or orbital locally advanced basal cell carcinoma, treated with Hedgehog pathway inhibitors.Results: All patients benefitted in terms of regression or stabilization of the neoplasm. In the first months of treatment, the HPIs were well tolerated, and the first important side effects appeared after about 5 months of continuous use of the drug.Conclusion: These data could lead to a new type of therapeutic scheme where neoadjuvant therapy could be followed by pulse therapy as an adjuvant to surgery.

BACKGROUND Asplenic or splenectomized patients have a higher risk (ranging from 10 to 50-fold) than the general population of developing an overwhelming post-splenectomy infection (OPSI). Thus, they should receive specific vaccinations to prevent bacterial infections and influenza. The aim of this meta-analysis was to estimate vaccination coverage (VC) with the recommended vaccines among splenectomized patients; strategies recommended in those studies to improve VC worldwide are considered as well. RESEARCH DESIGN AND METHODS Scopus, MEDLINE/PubMed, Google Scholar and ISI Web of Knowledge databases were searched. Research papers, short reports, reviews, and meta-analyses published between January 1, 2010 and July 18, 2020 were included; no geographic restrictions were included. Twenty-four studies were included in the meta-analysis. RESULTS For anti-pneumococcal vaccination, coverage was 55.1% (95%CI = 41.0-69.2%), for anti-Hib 48.3% (95%CI = 34.3-52.3%), for anti-meningococcal C/ACYW135 33.7% (95%CI = 23.6-43.9%), for anti-meningococcal B 13.3% (95%CI = 7.0-19.5%) and for anti-influenza 53.2% (95%CI = 22.0-84.4%). Most studies determined a lack of adherence to international guidelines by healthcare workers and suggested the need to better educate health professionals in the management of post-splenectomy patients. CONCLUSIONS The meta-analysis showed the suboptimal immunization coverage for the vaccines recommended for asplenic patients. Greater efforts must be made by public health professionals to increase VC in this group of patients at risk. Introducing specific prophylaxis protocols in the clinical routine seems to guarantee better immunization compliance in those patients.

Despite recent progress and the publishing of several clinical guidelines on the management of advanced basal cell carcinoma, there is still no comprehensive set of clinical guidelines addressing the complexity inherent to the use of Hedgehog pathway inhibitors in the treatment of advanced basal cell carcinoma in real-world clinical practice. To develop practical and valuable tools that help specialists improve the clinical management of these patients, we sought the opinion of expert physicians with extensive knowledge and experience in the treatment of advanced basal cell carcinoma.

Introduction: Mandibular defects reconstruction could result challenging in childhood, due to facial and mandibular growth patterns. For these reasons, the choice of the most suitable reconstructive option in pediatric patients, affected by mandibular malignancies, still objects of debate. Objective: The aim of our study was to compare our reconstructive schedules to the existing literature in order to give a personal contribute to the present panorama. Methods: We performed, in October 2019, a retrospective evaluation of pediatric patients treated for biopsy-proven mandibular malignancies at our Institute between January 2013 and December 2016. All of them received multimodal therapy in accordance with standard guidelines and their demographic, clinical, treatment, and outcome parameters were collected and analyzed. Results: We observed a shorter duration of surgery, a faster tracheostomy tube and feeding-tube removal, and a minor hospitalization in patients who received grafts transfer compared to those who underwent microsurgical mandibular reconstruction. After a 36-month period of follow-up, osteochondral grafts showed a pattern of growth similar to the mandibular epiphysis (condilylion-gonion linear and vertical ratio ranging to 0.96–1.03 and 1–1.02 at orthopantomogram, respectively). No bone consolidation delays and functional impairment were recorded. Conclusions: Free flaps mandibular reconstruction in children needs to be better assessed and proximal fibular epiphyseal free flap indication might deserve further studies. Osteochondral grafts find indication for lateral defects, 50–55 mm in maximum length and located in the mandibular ramus, without massive teeth or soft tissue defect. Condyle involvement does not represent an absolute contraindication to rib graft use.

BACKGROUND AND OBJECTIVES The current evidence regarding complications after salvage neck dissection (ND) for isolated regional recurrences (IRRs) in head and neck cancers is poor. The aim of this study is to evaluate the incidence and differences in complication rates of salvage ND after primary surgery, radiotherapy, chemoradiotherapy, or combined treatments. METHODS This was a multicentric retrospective study on 64 patients who underwent salvage ND for IRR in three Italian institutes between 2008 and May 2020. RESULTS Complications were detected in 7 of the 34 patients (20.8%) and surgeons described difficult dissection in 20 patients (58.82%). Accidental vascular ligations or nervous injury during surgery were never detected. None of the variables analyzed were statistically significant in predicting the risk of complications, disease-free survival, or overall survival. CONCLUSIONS IRR represents a rare entity among total relapses. The incidence of complications after salvage ND for IRR is higher than after primary surgery but at an acceptable rate in experienced hands. However, an adequate balance between functional and oncological outcomes is mandatory.

AimsAmeloblastoma is a rare odontogenic tumour with an aggressive local behaviour. Mutations in the mitogen-activated protein kinase pathway, namely BRAF V600E mutations, are a common finding. To date, there is no clear correlation between BRAF V600 mutation and clinical outcome.MethodsWe retrospectively reviewed the medical records of patients who underwent surgery for ameloblastoma between May 1998 and June 2018, at 11 participating Italian centres. BRAF mutational status was evaluated by quantitative PCR/pyrosequencing. The primary end points were to determine BRAF mutational status in primitive and recurrent ameloblastoma, and to assess the relapse-free interval (RFI); the secondary end point was to investigate the correlation of BRAF mutational status with the clinical features of the tumour and survival outcomes.ResultsOverall, 74 patients were included: 33 (44.5%) were BRAF wild type and 41 (55.4%) BRAF V600 mutated. BRAF V600 mutated ameloblastomas occurred more frequently in younger patients (p=0.0031), were located at the mandible (p=0.0009) and presented with unicystic variant. After a median follow-up of 60 months, 21 (28.3%) patients relapsed (30.3% and 26.8% in the BRAF wild type and BRAF mutated group, respectively). At univariable Cox models, none of the investigated variables, including microscopic margin involvement, was associated with RFI.ConclusionsLocal recurrence occurs in 30% of patients with ameloblastoma. BRAFV600 mutation is associated with younger age, mandibular localisation and with unicystic ameloblastoma. Neither BRAF mutation nor microscopically positive surgical margins were associated with RFI. Further studies are needed to elucidate outcomes of this rare disease according to clinical, histopathological and comprehensive molecular features.

Introduction The extensive use of oral and inactivated poliovirus (PV) vaccines has driven progress toward the global eradication of wild PV2 and PV3 and the elimination of PV1 in most countries, including Italy. Although the persistence of circulating neutralizing antibodies among the vaccinated is unclear, it is estimated that > 99% of the population vaccinated according to the recommended protocol should be protected for at least 18 years. Methods This study evaluated the seroprevalence of anti-PV neutralizing antibodies and the long-term immunogenicity of the oral poliovirus vaccine (OPV) in a sample of medical students and residents of the University of Bari who attended the Hygiene Department for a biological risk assessment between April 2014 and October 2020. Results The prevalence of protected vaccinated individuals was > 90% for PV1, PV2, and PV3. Specifically, >99% of the study group was protected against PV1, > 98% against PV2, and almost 93% against PV3. Protective antibodies against all three viruses persisted for at least up to 18 years after administration of the last OPV dose, with PV1 and PV2 antibodies detected in > 95% of the participants > 30 years after the last OPV dose. Conclusions The childhood series of four doses of OPV guarantees a long duration of protection, despite the elimination of the virus and therefore the absence of a natural booster. However, until PV1 is completely eradicated, maximum vigilance on the part of public health institutions must be maintained.

Visual drug cues are powerful triggers of craving in drug abusers contributing to enduring addiction. According to previous qualitative reviews, the response of the orbitofrontal cortex to such cues is sensitive to whether subjects are seeking treatment. Here we re-evaluate this proposal and assessed whether the nature of the drug matters. To this end, we performed a quantitative meta-analysis of 64 neuroimaging studies on drug-cue reactivity across legal (nicotine, alcohol) or illegal substances (cocaine, heroin). We used the ALE algorithm and a hierarchical clustering analysis followed by a cluster composition statistical analysis to assess the association of brain clusters with the nature of the substance, treatment status, and their interaction. Visual drug cues activate the mesocorticolimbic system and more so in abusers of illegal substances, suggesting that the illegal substances considered induce a deeper sensitization of the reward circuitry. Treatment status had a different modulatory role for legal and illegal substance abusers in anterior cingulate and orbitofrontal areas involved in inter-temporal decision making. The class of the substance and the treatment status are crucial and interacting factors that modulate the neural reactivity to drug cues. The orbitofrontal cortex is not sensitive to the treatment status per se, rather to the interaction of these factors. We discuss that these varying effects might be mediated by internal predispositions such as the intention to quit from drugs and external contingencies such as the daily life environmental availability of the drugs, the ease of getting them and the time frame of potential reward through drug consumption.

The neuromodulation induced by neurofeedback training (NFT) remains a matter of debate. Investigating the modulation of brain activity specifically associated with NF requires controlling for multiple factors, such as reward, performance, congruency between task and targeted brain activity. This can be achieved using sham feedback (FB) control condition, equating all aspects of the experiment but the link between brain activity and FB. We aimed at investigating the modulation of individual alpha EEG activity induced by NFT in a double-blind, randomized, sham-controlled study. Forty-eight healthy participants were assigned to either NF (n=25) or control (n=23) group and performed alpha upregulation training (over 12 weeks) with a wearable EEG device. Participants of the NF group received FB based on their individual alpha activity. The control group received the auditory FB of participants of the NF group. An increase of alpha activity across training sessions was observed in the NF group only (p). This neuromodulation was selective in that it was not observed for theta (4-8Hz) and low beta (13-18Hz) activities. While alpha upregulation was found in the NF group only, psychological outcome variables showed increased feeling of control, decreased anxiety level and increased relaxation feeling in both the NF and control groups, without any significant difference between groups. This is interpreted in terms of learning context and placebo effects. Our results pave the way to self-learnt, NF-based neuromodulation with light-weighted, wearable EEG systems.

Surveillance of Adverse Events Following Immunization (AEFIs) is a crucial part of vaccination strategies because the most important concern of “No-vax group” is the safety of vaccination. According to UE laws, in Italy a passive surveillance system of AEFIs is established by law and managed by National Drug Authority (AIFA) and Regional Health Governments. The performance of surveillance system is different in the 21 Italian Regions and in some Region, such as Puglia, the AEFIs reporting rate has been, for several years, lower than National figure. The implementation of AEFIs active surveillance projects could increase the performance of AEFIs surveillance system, also after the end of the project. In Puglia, since 2017, May to 2018, November, an active surveillance of AEFIs has been established, focused on MMRV vaccine. In this study, we analysed the AEFIs general picture in Puglia in 2016 and 2019, before and after active surveillance project. The source of data is the AIFA database; data were reported as number of AEFI and rate for Puglia population (reporting rate RR). The AEFIs were classified as serious, not serious and unclassifiable and causality assessment was performed according to WHO recommendations. The number of AEFIs detected by the passive surveillance system is 91 for 2016 (RR 2,2 per 100.000 people), and 168 for 2019 (RR 4,2 per 100.000 people). The percentage of serious AEFIs was 23.1% (21/91) in 2016 and 31% (52/168) in 2019 and unclassifiable AEFIs were 22% (20/91) in 2016 and 0 in 2019. The percentage of serious AEFIs for which the result of causality assessment was “consistent” is 23,8% (5/21) in 2016 and 55,8% (29/52) in 2019. The experience of AEFIs active surveillance project increase the performance of AEFIs surveillance system. From 2016 (pre-project time) to 2019 (post-project time) the number of AEFIs detected was doubled, the number of unclassifiable AEFIs (proxy of poor reliability of the system) was reduced to zero. Key messages AEFIs passive surveillance system could be affected by underreporting and lack of quality. The AEFIs active surveillance project are an important occasion of traineeship for vaccinovigilance system, that could increase the sensibility and the reliability.

International audience; Cognitive reserve is present in Alzheimer's disease (AD) seniors with high education attainment making them clinically resilient to extended brain neuropathology and neurodegeneration. Here, we tested whether subjective memory complaint (SMC) seniors with AD neuropathology and high education attainment of the prospective INSIGHT-preAD cohort (Paris) may present abnormal eyesclosed resting state posterior electroencephalographic rhythms around individual alpha frequency peak, typically altered in AD patients. The SMC participants negative to amyloid PET AD markers (SMCneg) with high (over low-moderate) education level showed higher posterior alpha 2 power density (possibly "neuro-protective"). Furthermore, amyloid PET-positive SMC (SMCpos) participants with high (over low-moderate) education level showed higher temporal alpha 3 power density (possibly "neuro-protective") and lower posterior alpha 2 power density (possibly "compensatory"). This effect may reflect cognitive reserve as no differences in brain graywhite matter, and cognitive functions were observed between these SMCpos/SMCneg subgroups. Preclinical Alzheimer's neuropathology may interact with education attainment and neurophysiological mechanisms generating cortical alpha rhythms around individual alpha frequency peak (i.e., alpha 2 and 3) in quiet wakefulness.

Patients with cancer have an increased risk of developing severe forms of coronavirus disease 2019, and patients with advanced cancer who are followed at home represent a particularly frail population. Although with substantial differences, the challenges that cancer care professionals have to face during a pandemic are quite similar to those posed by natural disasters. We have already managed the oncological home care service in L'Aquila (middle Italy) after the 2009 earthquake. With this letter, we want to share the procedures and tools that we have started using at the home care service of the Tuscany Tumor Association during the coronavirus disease 2019 pandemic.

All kinds of ear, nose, and throat and maxillofacial surgery (ENT/MFS) procedures are being increasingly performed in the elderly although old age is a major risk factor for increased postoperative complications. With only scarce evidence on the topic, surgeons are asked to critically evaluate their procedures’ indications and outcomes to balance the treatment risks and benefits. Our primary aim was to identify predictive factors for surgical outcomes in this setting and to create a predictive model for a tailored risk assessment. We analyzed a case series of 435 patients from an institutional clinical database at our academic tertiary care center. Multivariate logistic regression was used to identify all possible covariates and nomograms using stepwise backward method were generated. The performance was assessed by calibration curves and c-index. Overall complication rate was 18.3% within the first 30 days and the need for re-intervention was 5.9%. For those under general anesthesia, we identified specific risk factors and developed three risk-predicting models of overall, early, and late complications. All of the nomograms showed satisfactory accuracy with a c-index of 0.83, 0.75, 0.86, and 0.82, respectively. Using clinical preoperative variables, we constructed a model for predicting major adverse events in ENT/MFS patients. In our experience, patients over 65 showed a non-negligible risk for postoperative complications depending on several factors. Such tools might help in decision-making, by increasing the risk-awareness of clinicians, to better address peri-operative and post-operative care of these patients.

Wearable EEG systems have become accessible to researchers and clinicians over the last decade, thus requiring neurotechnology companies to seek for outstanding EEG signal quality. Here, we show that the melomind™ headset equipped with dry electrodes (myBrain Technologies, Paris, France) allows the recording of reliable electro-cortical dynamics as compared to a wet-based standard-EEG system (actiCAP, Brain Products GmbH, Gilching, Germany). EEGs were acquired simultaneously from the two systems while thirteen subjects underwent a visual oddball, a steady-state visually-evoked potentials (SSVEPs) and two resting-state (RS) tasks. RS were acquired with eyes-closed and eyes-open (2 minutes each) and repeated twice (before and after the cognitive tasks). During the oddball task, participants responded on a gamepad when a target-stimulus was displayed. In the SSVEPs, visual responses were elicited at 15 and 20 Hz through a series of 15-second stimuli presented 5 times each. The power of theta- [4-8 Hz], alpha- [8-13 Hz], and beta- [13-30 Hz] band was extracted from the two RS. The signal-to-noise-ratio in the 15 (± 1) and 20 (± 1) Hz range was computed from the SSVEPs. The shape of the N2/P300 complex was analysed from the oddball task. Strong correlations resulted between the parameters obtained from the two EEG systems (0.53 < Pearson’s r < 0.97). Bland and Altman analysis revealed small dissimilarities between the two systems, with values laying in the 95% confidence interval in all the tasks. Our results demonstrate that the melomind™ is an affordable solution to reliably assess humans’ electro-cortical dynamics at-rest and during cognitive tasks, thus paving the way to its use in neuroscience studies and brain-computer interfaces.

Limb apraxia (LA) refers to a high-order motor disorder characterized by the inability to reproduce transitive actions on commands or after observation. Studies demonstrate that action observation and action execution activate the same networks in the human brain, and provides an onlooker's motor system with appropriate cognitive, motor and sensory-motor cues to flexibly implementing action-sequences and gestures. Tellingly, the temporal dynamics of action monitoring has never been explored in people suffering from LA. To fill this gap, we studied the electro-cortical signatures of error observation in human participants suffering from acquired left-brain lesions with (LA+) and without (LA-) LA, and in a group of healthy controls (H). EEG was acquired while participants observed from a first-person perspective (1PP) an avatar performing correct or incorrect reach-to-grasp a glass action in an immersive-virtual environment. Alterations of typical EEG signatures of error observation in time (early error positivity; Pe) and time-frequency domain (theta band-power) were found reduced in LA+ compared with H. Connectivity analyses showed that LA+ exhibited a decreased theta phase synchronization of both the frontoparietal and frontofrontal network, compared with H and LA-. Moreover, linear regression analysis revealed that the severity of LA [test of upper LA (TULIA) scores] was predicted by mid-frontal error-related theta activity, suggesting a link between error monitoring capacity and apraxic phenotypes. These results provide novel neurophysiological evidence of altered neurophysiological dynamics of action monitoring in individuals with LA and shed light on the performance monitoring changes occurring in this disorder.

Purpose Local flaps are currently considered the main reconstructive option for medium-size oral and peri-oral defects; however, their indications are sometimes challenging to select. The aim of this study was to critically analyse their selection and to propose a therapeutic algorithm. Materials and methods We performed a search on PubMed regarding the medium-size oral and peri-oral defects reconstruction, and we collected data on the aetiology, the location of the defect, the type of flap used and postoperative complications. The final proposed treatment algorithm was the product of this analysis. Results We found 111 articles and 2504 flaps (236 buccinator flaps, 60 masseter flaps, 466 facial artery myomucosal flaps, 285 tongue flaps, 95 palatal flap, 525 buccal fat pad flaps and 835 local lip flaps). The most frequent defect localizations included floor of mouth (203 flaps), cheek (242 flaps), anterior hard palate (418 flaps) and upper and lower lip (274 and 559 flaps). Partial flap necrosis and dehiscence occurred in 3% of cases whereas total necrosis in 1%. Conclusions Local flaps are a good option for oral and perioral defect reconstruction. An appropriate choice of the flap to be used based on the location of the defect is essential for a correct reconstruction.

Objectives The author analyse the impact of extracapsular lymph node spread and bone engagement in the ipsilateral neck of patients suffering squamous cell carcinoma (SCC) of the lower lip. Methods The data of 56 neck dissections performed in patients suffering SCC of the lower lip between January 2000 and December 2008 were retrospectively analysed. Statistical analysis was performed with the Kaplan-Meier life table method, and the survival rate was investigated with the log rank statistic and significance test. The values were considered statistically significant at p Results Nine patients took advantage from simultaneous treatment of tumor and prophylactic neck dissection (level I-III), reaching 100% survival rate. Patients suffering metastasized disease, who received radical neck dissection at the time of tumor treatment, presented 83.3% survival rate. Patients who underwent previous surgery and radiotherapy presented worse prognosis although radical neck dissection in case of extra-capsular spread only (24.7%) and osseous engagement (22.2%). Conclusion Prophylactic neck dissection (level I-III) is recommended in T3-T4 N0 SCC. Simultaneous treatment of tumor and cervical lymph nodes provides a better prognosis as respect to delayed nodal management. Extra-capsular spread with or without bone engagement represents independent risk factor responsible for high mortality rate of SCC of the lower lip.

Piezosurgery is commonly used in different field of craniomaxillofacial surgery; since its introduction it has become one of the widely adopted technique for performing osteotomies in orthognathic surgery, distraction osteogenesis and dentoalveolar surgery. Little has been written regarding ultrasonic system for temporomandibular joint surgery (TMJ). In this prospective study we describe the use of piezoelectric device for ankylosis of the TMJ.We enrolled in this study 19 patients, 10 males and 9 females, mean (SD) age 24.6 (7.6) years, affected by unilateral ankylosis of TMJ who were surgically managed between January 2009 and December 2014 by interpositional arthroplasty with temporomyofascial muscle flap. We adopted in all cases a preauricular approach with temporal extension. The ankylotic block was removed with piezoelectric device in 9 patients and using traditional rotary bur in 10 cases. We investigated and compared the following parameters as surgical outcomes: intraoperative bleeding, duration of operation, incidence of infection, postoperative swelling and hematoma, mouth opening, nerve impairment and rate of recurrence.We noticed a substantial reduction in bleeding with the piezoelectric bone cutter when compared to traditional mechanical surgery (103 ml versus 117 ml; p 0.05); however, we did not report any severe bleeding from the pterygoid plexus or maxillary artery. Operating time was longer in the piezo group (101 min versus 88 min; p 0.05). There was a lower incidence of postoperative hematoma and swelling following piezoosteotomy. However, regarding postoperative nerve impairment and infection we did not observe any differences between the two groups. At one year follow-up mean (SD) mouth opening was 34 (4.3) mm. We did not report recurrence of the disease.Piezoelectric bone removal for the release of ankylosis of the TMJ is associated with minimal bleeding and few postoperative complications. We believe that piezosurgery allows surgeons to achieve better results compared to a traditional surgery. It is a possible alternative due to the clinical benefits demonstrated.
