Abstract
BACKGROUND COVID-19 pandemic is thought to have changed the epidemiology of some pediatric neurosurgical disease: among them are the intracranial complications of sinusitis and otitis (ICSO). According to some studies on a limited number of cases, both streptococci-related sinusitis and ICSO would have increased immediately after the pandemic, although the reason is not clear yet (seasonal changes versus pandemic-related effects). The goal of the present survey of the European Society for Pediatric Neurosurgery (ESPN) was to collect a large number of cases from different European countries encompassing the pre-COVID (2017-2019), COVID (2020-2021), and post-COVID period (2022-June 2023) looking for possible epidemiological and/or clinical changes. MATERIAL AND METHODS An English language questionnaire was sent to ESPN members about year of the event, patient's age and gender, presence of immune-deficit or other favoring risk factors, COVID infection, signs and symptoms at onset, site of primary infection, type of intracranial complication, identified germ, type and number of surgical operations, type and duration of medical treatment, clinical and radiological outcome, duration of the follow-up. RESULTS Two hundred fifty-four cases were collected by 30 centers coming from 14 different European countries. There was a statistically significant difference between the post-COVID period (129 children, 86 cases/year, 50.7% of the whole series) and the COVID (40 children, 20 cases/year, 15.7%) or the pre-COVID period (85 children, 28.3 cases/year, 33.5%). Other significant differences concerned the presence of predisposing factors/concurrent diseases (higher in the pre-COVID period) and previous COVID infection (higher in the post-COVID period). No relevant differences occurred as far as demographic, microbiological, clinical, radiological, outcome, morbidity, and mortality data were concerned. Paranasal sinuses and middle ear/mastoid were the most involved primary site of infection (71% and 27%, respectively), while extradural or subdural empyema and brain abscess were the most common ICSO (73% and 17%, respectively). Surgery was required in 95% of cases (neurosurgical and ENT procedure in 71% and 62% of cases, respectively) while antibiotics in 99% of cases. After a 12.4-month follow-up, a full clinical and radiological recovery was obtained in 85% and 84% of cases, respectively. The mortality rate was 2.7%. CONCLUSIONS These results suggest that the occurrence of ICSO was significantly increased after the pandemic. Such an increase seems to be related to the indirect effects of the pandemic (e.g., immunity debt) rather than to a direct effect of COVID infection or to seasonal fluctuations. ICSO remain challenging diseases but the pandemic did not affect the management strategies nor their prognosis. The epidemiological change of sinusitis/otitis and ICSO should alert about the appropriate follow-up of children with sinusitis/otitis.

Abstract
OBJECTIVE Patients with focal drug resistant epilepsy are excellent candidates for epilepsy surgery. Status epilepticus (SE) and seizure clusters (SC), described in a subset of patients, have both been associated with extended epileptogenic cerebral networks within one or both hemispheres. In this retrospective study, we were interested to determine if a history of SE or SC is associated with a worse surgical outcome. METHODS Data of 244 patients operated between 2000 to 2018 were reviewed, with a follow-up of at least 2 years. Patients with a previous history of SE or SC were compared to operated patients without these conditions (control group, CG). RESULTS We identified 27 (11%) and 38 (15.5%) patients with history of SE or SC, respectively. No difference in post-operative outcome was found for SE and SC patients. Compared to the control group, patients with a history of SE were diagnosed and operated significantly at earlier age(p = 0.01), and after a shorter duration of the disease (p = 0.027), but with a similar age of onset. SIGNIFICANCE A history of SE or SC was not associated with a worse post-operative prognosis. Earlier referral of SE patients for surgery suggests a heightened awareness regarding serious complications of recurrent SE by the referring neurologist or neuropediatrician. While the danger of SE is evident, policies to underline the impact for SC or very frequent seizures might be an efficient approach to accelerate patient referral also for this patient group.

Abstract
Introduction Artificial Intelligence tools are being introduced in almost every field of human life, including medical sciences and medical education, among scepticism and enthusiasm. Research question to assess how a generative language tool (Generative Pretrained Transformer 3.5, ChatGPT) performs at both generating questions and answering a neurosurgical residents' written exam. Namely, to assess how ChatGPT generates questions, how it answers human-generated questions, how residents answer AI-generated questions and how AI answers its self-generated question. Materials and methods 50 questions were included in the written exam, 46 questions were generated by humans (senior staff members) and 4 were generated by ChatGPT. 11 participants took the exam (ChatGPT and 10 residents). Questions were both open-ended and multiple-choice.8 questions were not submitted to ChatGPT since they contained images or schematic drawings to interpret. Results formulating requests to ChatGPT required an iterative process to precise both questions and answers. Chat GPT scored among the lowest ranks (9/11) among all the participants). There was no difference in response rate for residents' between human-generated vs AI-generated questions that could have been attributed to less clarity of the question. ChatGPT answered correctly to all its self-generated questions. Discussion and conclusions AI is a promising and powerful tool for medical education and for specific medical purposes, which need to be further determined. To request AI to generate logical and sound questions, that request must be formulated as precise as possible, framing the content, the type of question and its correct answers.

Abstract
(1) Background: Despite the advantages of COVID-19 vaccination, rare cases of acute hepatitis developing after the administration of the COVID-19 vaccine or the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection have been reported. The aim of the study is to describe a case series of patients who experienced the onset of acute hepatitis, with or without autoimmune features, following SARS-CoV-2 vaccination or infection and to hypothesize a genetic susceptibility in the pathogenesis. (2) Methods: A group of patients with acute onset hepatitis following SARS-CoV-2 vaccination or infection were evaluated in our hepatology outpatient clinic, where they underwent biochemical and autoimmune tests. Hepatitis A (HAV), B (HBV), and C virus (HCV), cytomegalovirus (CMV), Epstein-Barr virus (EBV), and human immunodeficiency virus (HIV) infections were excluded. Patients with a diagnosis of autoimmune hepatitis (AIH) or drug-induced liver injury (DILI) underwent HLA typing and histological testing. (3) Results: Five patients experienced new-onset AIH after COVID-19 vaccination, one of which developed mild symptoms after vaccination that strongly worsened during subsequent SARS-CoV-2 infection. One patient had AIH relapse after COVID-19 vaccination while on maintenance immunosuppressive treatment. All of them had HLA DRB1 alleles known to confer susceptibility to AIH (HLA DRB1*03,*07,*13,*14), and in three of them, HLA DRB1*11 was also detected. Two patients developed acute hepatitis without autoimmune hallmarks which resolved spontaneously, both positive for HLA DRB1*11. (4) Conclusions: An association between AIH and COVID-19 vaccine or infection can be hypothesized in individuals with a genetic predisposition. In patients without autoimmune features and spontaneous improvement of hypertransaminasemia, the diagnosis of drug-induced liver injury (DILI) is probable. Further studies are needed to determine the presence of an actual association and identify a possible role of HLA DRB1*11 in the pathogenesis of acute liver injury after SARS-CoV2 vaccination or infection.

Abstract
Purpose From the beginning of the Severe Acute Respiratory Syndrome CoronaVirus-2 (SARS-CoV2) pandemic, different cases of a cholangiopathy with features of secondary sclerosing cholangitis in critically ill patients (SSC-CIP) have been reported. Patients developing it are generally recovering from severe Coronavirus disease 19 (COVID-19) and required intensive care unit (ICU) admission and mechanical ventilation. Many of them have been administered with ketamine during their ICU stay. The pathogenesis of this novel disease is still debated, and, since prognosis is poor, efforts are needed in order to better understand it. Patients and Methods In this review, we focused our attention on COVID-19 SSC clinical, imaging, and histology findings in order to clarify the different pathogenetic options, particularly in regard of the ischemic-direct viral damage and ketamine-related theories, beginning with a recapitulation of SSC-CIP and ketamine-induced cholangiopathy in abusers. The research has been conducted using PubMed and Google Scholar databases. Key-words were "Secondary Sclerosing Cholangiopathy", "SSC-CIP", "Secondary Sclerosing Cholangiopathy in critically ill patients", "Ketamine and cholangiopathy", "Ketamine abusers and liver disease", "Ketamine-related cholangiopathy", "SARS-CoV2 infection and liver disease", "post Covid-19 secondary sclerosing cholangitis", "Covid-19 cholangiopathy". Results Many authors, based on the clinical, histological, imaging, and prognostic features of the disease, have pointed out the similarities between post COVID-19 SSC and SSC-CIP; however, peculiar features in the former were not previously observed. Therefore, a direct viral cytopathic action and SARS-CoV2-related coagulopathy are considered the most likely causes. On the other hand, ketamine, with the available data, cannot be surely linked as the main determinant cause of cholangiopathy. Moreover, ketamine-induced cholangitis (KIC) presentation is different from post COVID-19 SSC. Its role as a cofactor precipitating the disease cannot be ruled out. Conclusion Post COVID-19 SSC is a rare clinical entity following severe COVID-19 disease. The most accepted theory is that a sum of different insults determines the disease: biliary ischemia, direct viral damage, toxic bile, possibly worsened by ketamine and hyperinflammation due to the cytokine storm. Given the severe prognosis of the disease, with persistent cholangiopathy, organ failure, and orthotopic liver transplantation (OLT), further study on this novel clinical entity is needed.

Abstract
OBJECTIVE To evaluate tocilizumab (TCZ) efficacy in refractory Behcet's Disease (BD) patients. METHODS Multicenter study of 30 patients fulfilling the International Criteria for BD and treated with TCZ at different European referral centres. The clinical response was evaluated at 6 months (M6) from TCZ initiation. RESULTS Ninety percent of BD patients were refractory or intolerant to anti-TNF-α agents. Overall, TCZ was effective in 25 (83%) BD patients of whom 18 (60%) and 7 (23%) were complete and partial responders, respectively. The complete response was of 67%, 60% and 42% in patients with uveitis (18/30), neurological (5/30) and muco-cutaneous and/or articular (7/30) manifestations, respectively. TCZ had a significant steroid-sparing effect allowing to decrease the median daily prednisone dose from 20mg/day [10-40] to 9mg [5-13] at 6 months (p < 0.001). The number of BD patients needing concomitant DMARDs therapy fell from 7 (23%) to 4 (13%) at 6 months. Mild to moderate side effects were observed in 6 (20%) patients and 3 (10%) presented serious adverse events [pneumonia, intestinal perforation, and septicemia] requiring therapy discontinuation in 2 cases. CONCLUSION TCZ seems an effective alternative to anti-TNF-α agents in BD uveitis and neurological manifestations.

Abstract
PURPOSE To evaluate primary patency at 12 months after endovascular therapies in hepatic artery stenosis. METHODS A retrospective review of all endovascular interventions for hepatic artery stenosis (HAS) after liver transplantation that occurred between June 2013 and November 2020 was performed at a single institution in France. Follow up occurred from 1 month to 4 years (median 15 months). The treatment consisted of dilation with a balloon or stent. We analyzed short-term (technical success and complications) and long-term outcomes (liver function, arterial patency, graft survival at 12 months (GS), and reintervention). We also compared percutaneous balloon angioplasty (PBA) with stent placement. PBA alone was used if < 30% residual stenosis of the hepatic artery was achieved. Stenting was performed if there was greater than 30% residual stenosis and in the case of complications (dissection or rupture). RESULTS A total of 18 stenoses were suspected on the basis of routine surveillance duplex ultrasound imaging (peak systolic velocity > 200 cm/s, systolic accelerating time > 10 ms and resistive index < 0.5), all of which were confirmed by angio CT, but only 17 were confirmed by angiography. Seventeen patients were included (14 males, mean age 57 years; and three females, mean age 58 years). Interventions were performed in 17 cases (95%) with PBA only (5/17), stent only (5/17) or both (4/17). Immediate technical success was 100%. Major complications occurred in 1 of 17 cases (5.8%), consisting of target vessel dissection. The analysis of the three (groups PBA only, stent only or both) showed the same procedural success (100%), GS (100%) and normal liver function after the procedures but different rates of complications (20% vs. 0% vs. 0%), arterial patency at 12 months (60% vs. 80% vs. 85%) (p = 0.4), early stenosis (40% vs. 80% vs. 0%) or late stenosis (60% vs. 20% vs. 100%) and requirement for reintervention (40% vs. 20% vs. 14%) (p = 0.56). CONCLUSION This study suggests that PBA, stent, or both procedures show the same primary patency at 12 months. It is probably not a definitive answer, but these treatments are safe and effective for extending graft survival in the context of graft shortages.

Abstract
The hepatitis B virus is responsible for most of the chronic liver disease and liver cancer worldwide. As actual therapeutic strategies have had little success in eradicating the virus from hepatocytes, and as lifelong treatment is often required, new drugs targeting the various phases of the hepatitis B virus (HBV) lifecycle are currently under investigation. In this review, we provide an overview of potential future treatments for HBV.

Abstract
Since its outbreak in China in December 2019 a novel Coronavirus, named SARS-CoV-2, has spread worldwide causing many cases of severe pneumonia, referred to as COVID-19 disease, leading the World Health Organization to declare a pandemic emergency in March 2020. Up to now, no specific therapy against COVID-19 disease exists. This paper aims to review COVID-19 treatment options currently under investigation. We divided the studied drugs into three categories (antiviral, immunomodulatory and other drugs). For each molecule, we discussed the putative mechanisms by which the drug may act against SARS-CoV-2 or may affect COVID-19 pathogenesis and the main clinical studies performed so far. The published clinical studies suffer from methodological limitations due to the emergency setting in which they have been conducted. Nevertheless, it seems that the timing of administration of the diverse categories of drugs is crucial in determining clinical efficacy. Antiviral drugs, in particular Remdesivir, should be administered soon after symptoms onset, in the viraemic phase of the disease; whereas, immunomodulatory agents, such as tocilizumab, anakinra and steroids, may have better results if administered in pneumonia/hyperinflammatory phases. Low-molecular-weight heparin may also have a role when facing COVID-19-related coagulopathy. Up to now, treatment choices have been inferred from the experience with other coronaviruses or viral infection outbreaks. Hopefully, in the near future, new treatment strategies will be available thanks to increased knowledge on SARS-CoV2 virus and COVID-19 pathogenesis. In the meanwhile, further well-designed clinical trials are urgently needed to establish a standard of care in COVID-19 disease.

Abstract
A major research area in Computer Assisted Intervention (CAI) is to aid laparoscopic surgery teams with Augmented Reality (AR) guidance. This involves registering data from other modalities such as MR and fusing it with the laparoscopic video in real-time, to reveal the location of hidden critical structures. We present the first system for AR guided laparoscopic surgery of the uterus. This works with pre-operative MR or CT data and monocular laparoscopes, without requiring any additional interventional hardware such as optical trackers. We present novel and robust solutions to two main sub-problems: the initial registration, which is solved using a short exploratory video, and update registration, which is solved with real-time tracking-by-detection. These problems are challenging for the uterus because it is a weakly-textured, highly mobile organ that moves independently of surrounding structures. In the broader context, our system is the first that has successfully performed markerless real-time registration and AR of a mobile human organ with monocular laparoscopes in the OR.

Abstract
Hepatitis C virus represents an important global health issue with 71 million of infected people in the word. Direct-acting antivirals are quite new molecules that hit specific Hepatitis C virus proteins useful for viral replication and assembly. Notably, Direct-acting antivirals bring to high sustained virological response rates showing also a great safety profile. This treatment revolution had an impact on transplantation world, in fact the number of liver transplants due to Hepatitis C virus-related cirrhosis and hepatocellular carcinoma is quickly decreasing. Even if this therapy has achieved excellent results in terms of morbility and mortality rates' reduction, there are some debated issues to consider. In the present review the main clinical challenges in every-day management of Hepatitis C virus patients treated with Direct-acting antivirals and the debated effects of viral clearance (metabolic, cardiovascular, immunologic and neoplastic) are discussed. The detection of barriers that can preclude the delivery of Hepatitis C virus care, is the most complex challenge for the scientific community. To obtain the Hepatitis C virus global eradication by 2030, as the World Health Organization has set, will be complex and laborious and will need a further multilevel effort.

Abstract
Magnetic resonance imaging (MRI) has become the reference imaging for the management of a large number of diseases. The number of MR examinations increases every year, simultaneously with the number of patients receiving a cardiac electronic implantable device (CEID). A CEID was considered an absolute contraindication for MRI for years. The progressive replacement of conventional pacemakers and defibrillators by MR-conditional CEIDs and recent data on the safety of MRI in patients with "MR-nonconditional" CEIDs have progressively increased the demand for MRI in patients with a CEID. However, some risks are associated with MRI in CEID carriers, even with "MR-conditional" devices because these devices are not "MR-safe". A specific programing of the device in "MR-mode" and monitoring patients during MRI remain mandatory for all patients with a CEID. A standardized patient workflow based on an institutional protocol should be established in each institution performing such examinations. This joint position paper of the Working Group of Pacing and Electrophysiology of the French Society of Cardiology and the Société française d'imagerie cardiaque et vasculaire diagnostique et interventionnelle (SFICV) describes the effect and risks associated with MRI in CEID carriers. We propose recommendations for patient workflow and monitoring and CEID programming in MR-conditional, "MR-conditional nonguaranteed" and MR-nonconditional devices.

Abstract
PURPOSE To compare the assessment of diffuse interstitial myocardial fibrosis in valvular diseases using cardiac magnetic resonance (CMR) extracellular volume fraction (ECV) quantification and serum biomarkers of collagen turnover using results of myocardial biopsy as standard of reference. MATERIALS AND METHODS This prospective monocentric study included consecutive patients before aortic valvular replacement. All patients underwent: i), 1.5T CMR with pre and post contrast T1 mapping sequence and ECV computation; ii), serum quantification of matrix metalloproteinases (MMPs) and tissue inhibitor of metalloproteinases (TIMPs) and iii), myocardial biopsies were collected during surgery to assess collagen volume fraction (CVF). Patients with coronary artery disease were excluded. Correlation between native T1, ECV, CVF and serum biomarkers were assessed using Pearson correlation test. Agreement between basal anteroseptal ECV with global ECV was assessed using Bland-Altman test. RESULTS Twenty-one patients, 16 with aortic stenosis and 5 with aortic regurgitation were included. There were 12 men and 9 women with a mean age of 74.1±6.8 (SD) years (range: 32-84 years). Mean global ECV value was 26.7±2.7 (SD) % (range: 23.4-32.5%) and mean CVF value was 12.4±9.7% (range: 3.2-25.7%). ECV assessed at the basal anteroseptal segment correlated moderately with CVF (r=0.6; P=0.0026). There was a strong correlation and agreement between basal anteroseptal ECV and global ECV, (r=0.8; P<0.0001; bias 5.4±6.1%) but no correlation between global ECV and CVF (r=0.5; P=0.10). Global ECV poorly correlated with serum TIMP-1 (r=0.4; P=0.037) and MMP-2 (r=0.4; P=0.047). No correlation was found between serum biomarkers and basal anteroseptal- ECV or native T1. CONCLUSION In patients with severe aortic valvulopathy, diffuse myocardial fibrosis assessed by anterosepto-basal ECV correlates with histological myocardial fibrosis. Anteroseptobasal ECV strongly correlates with global ECV, which poorly correlates with TIMP-1 and MMP-2, serum biomarkers involved in the progression of heart failure.

Abstract
Background Neonatal adrenal hemorrhage is a relatively uncommon condition (0.2–0.55%). Various risk factors have been reported in addition to birth asphyxia, such as sepsis, coagulation disorders, traumatic delivery, and perinatal injuries. Adrenal hemorrhage usually affects the right adrenal gland (about 70% of cases) while it involves the bilateral adrenal gland only in 10% of cases. In most cases, the event is asymptomatic but, in others, it may be so devastating to determine death by bleeding or adrenal insufficiency. Case presentation A case of bilateral neonatal adrenal hemorrhage, with adrenal insufficiency, but with no important risk factors and favorable evolution in a male infant. Conclusions This case emphasizes the importance of keeping a non-interventional attitude, avoiding early surgery but carrying out a serial sonographic follow-up. Serial ultrasound monitoring is the most reliable approach during conservative management.

Abstract
BACKGROUND Children affected by neurodevelopmental disability could experience early pubertal changes at least 20 times more than the general population. Limited data about central precocious puberty (CPP) among children affected by cerebral palsy (CP) are available. METHODS This is a longitudinal, observational, retrospective, case-control study involving 22 children affected by CPP and CP (group A), 22 paired with CP but without CPP (group B), and 22 children with CPP without CP. Auxological, biochemical, and instrumental data were collected at diagnosis of CPP and at 2 follow-up visits. RESULTS No differences were detected between groups A (at baseline) and B. At diagnosis of CPP, height SDS adjusted for target height (H-TH SDS) was significantly reduced in A than in C (-0.63 ± 1.94 versus 1.56 ± 1.38), while basal LH and oestradiol levels were significantly elevated in A than in C. During follow-up, despite an effective treatment, growth impairment deteriorated in A than in C (Δ H-SDS from diagnosis of CPP to last follow-up: -0.49 ± 0.91 versus 0.21 ± 0.33, p = 0.023). CONCLUSIONS Diagnosis of CPP could be partially mislead in CP due to growth failure that got worse during follow-up despite therapy. CPP in CP seems to progress rapidly along time supporting the hypothesis of a more intense activation of hypothalamic-pituitary-gonadal-axis in these patients.

Abstract
Periodontitis (PD) is a chronic disease caused by the host inflammatory response to bacteria colonizing the oral cavity. In addition to tolerance to oral microbiome, a fine-tuned balance of IL-10 levels is critical to efficiently mount antimicrobial resistance without causing immunopathology. Clinical and animal studies support that adaptive T-helper (Th) cytokines are involved in the pathogenesis of alveolar bone destruction in PD. However, it remains unclear what type of Th response is related to human PD progression and what role IL-10 has on this process. We addressed the contribution of IL-10 in limiting Th1 and Th17 inflammatory response in murine and human PD. Through a combination of basic and translational approaches involving selected cytokine-deficient mice as well as human genetic epidemiology, our results demonstrate the requirement for IL-10 in fine-tuning the levels of Th17 (IL-17A and IL-17F) cytokines in experimental and human PD. Of novelty, we found that IL-17F correlated with protection in murine and human PD and was positively regulated by IL-10. To our knowledge, this is the first demonstration of the protective role for IL-17F in PD, its positive regulation by IL-10, and the potential differential role for IL-17A and IL-17F in periodontal disease.

Abstract
Intra-operative imaging techniques for obtaining the shape and morphology of soft-tissue surfaces in vivo are a key enabling technology for advanced surgical systems. Different optical techniques for 3-D surface reconstruction in laparoscopy have been proposed, however, so far no quantitative and comparative validation has been performed. Furthermore, robustness of the methods to clinically important factors like smoke or bleeding has not yet been assessed. To address these issues, we have formed a joint international initiative with the aim of validating different state-of-the-art passive and active reconstruction methods in a comparative manner. In this comprehensive in vitro study, we investigated reconstruction accuracy using different organs with various shape and texture and also tested reconstruction robustness with respect to a number of factors like the pose of the endoscope as well as the amount of blood or smoke present in the scene. The study suggests complementary advantages of the different techniques with respect to accuracy, robustness, point density, hardware complexity and computation time. While reconstruction accuracy under ideal conditions was generally high, robustness is a remaining issue to be addressed. Future work should include sensor fusion and in vivo validation studies in a specific clinical context. To trigger further research in surface reconstruction, stereoscopic data of the study will be made publically available at www.open-CAS.com upon publication of the paper.

Abstract
Colonoscopy is the reference medical examination for early diagnosis and treatment of colonic diseases. This minimally invasive technique allows endoscopists to explore the colon cavity and remove neoplasias - abnormal growths of tissue - which may develop into malignant tumors. The size, shape and appearance of a neoplasia are essential cues for diagnostic. However, the size is difficult to estimate because the absolute scale of the observed tissue is not directly conveyed in the 2D colonoscopic images. An erroneous size estimate may lead to inappropriate treatment. There currently exist no solutions to reproducible neoplasia size measurement adapted to colonoscopy. We propose a colonoscopic size measurement system for neoplasias. By using a simple planar geometry, the key technical problem is reduced to resolving scale. Our core contribution is introducing the Infocus-Breakpoint (IB) that allows us to resolve scale from a regular colonoscopic video. We define the IB as the lower limit of the colonoscope's depth of field. The IB corresponds to a precise colonoscope to tissue distance, called the reference depth, which we calibrate preoperatively. We detect the IB intraoperatively thanks to two novel modules: deformable Blur-Estimating Tracking (BET) and Blur-Model Fitting (BMF). With our system, the endoscopist may interactively measure the length and area of a neoplasia in a 2D colonoscopic image directly. Our system needs no hardware modification to standard monocular colonoscopes, yet reaching a size measurement accuracy of the order of a millimeter, as shown on several phantom and patient datasets.

Abstract
Clinical assessment and management of sleep disturbances in patients with mild cognitive impairment and dementia has important clinical and social implications. Poor sleep results in an increased risk of morbidities and mortality in demented patients and is a source of stress for caregivers. Sleep disturbances show high prevalence in mild cognitive impairment and dementia patients and they are often associated one to another in the same patient. A careful clinical evaluation of sleep disorders should be performed routinely in the clinical setting of individuals with cognitive decline. The Sleep Study Group of the Italian Dementia Research Association (SINDem) reviewed evidence from original research articles, meta-analyses and systematic reviews published up to December 2013. The evidence was classified in quality levels (I, II, III) and strength of recommendations (A, B, C, D, E). Where there was a lack of evidence, but clear consensus, good practice points were provided. These recommendations may not be appropriate for all circumstances and should therefore be adopted only after a patient's individual characteristics have been carefully evaluated.

Abstract
AIM To identify perinatal factors associated with sub-optimal neuromotor outcome in infants without evident central nervous system lesions (intraventricular hemorrhage/ periventricular leukomalacia), with gestational age ≤30 (group I) and of 31-32 weeks (group II). PATIENTS AND METHODS A total of 102 premature infants admitted to the Neonatal Intensive Care Unit of Pisa, at 26-32 weeks of gestation, were studied. Data about perinatal factors and TSH values at 3-4 days of life were collected. The assessment of neuromotor development was performed at 18 months of corrected age, using the locomotor subscale of the Griffiths Scales of Mental Development. RESULTS Risk factors supposed to be predictive of sub-optimal neuromotor outcome (odds ratio >1) were at ≤30 weeks: male sex, small for gestational age, patent duct arterious, respiratory distress syndrome, and at 31-32 weeks: Apgar at 5 min <7, respiratory distress syndrome, patent duct arterious and birth weight <1500 g. A strong correlation was also found between TSH screening values >4,3 mU/l and suboptimal neuromotor outcome in both groups. CONCLUSIONS Several perinatal factors, acting on an immature and more vulnerable nervous system, such as the pre-term one, different for different gestational ages, are associated with a sub-optimal neuromotor outcome. Higher, but within the normal range, TSH values at screening seem to be a strong risk factor for neuromotor outcome in preterm infants without intraventricular hemorrhage or periventricular leukomalacia.

Abstract
Laparoscopy is widely recognized as a feasible and safe approach to rectal cancer associated with an improved early outcome. Robotic surgery overcomes intrinsic limitation of laparoscopic surgery by a three-dimensional view and wristed instruments, improving its outcome as well. Robot-assisted rectal surgery resulted to be safe and feasible. Prospective studies demonstrated its efficacy in allowing a high rate of negative circumferential resection margins with a consequent reduction in solitary loco-regional recurrences. A better local disease control and a reduced surgical trauma will be the conceivable benefit of this surgery.

Abstract
BACKGROUND Retinol-binding protein 4 (RBP4) is an adipocyte-derived 'signal' that may contribute to the pathogenesis of insulin resistance and Type 2 diabetes. The relationship of RBP4 with insulin resistance and metabolic risk in human beings has been the subject of several studies. Subjects born small for gestational age (SGA) are at risk of insulin resistance and Type 2 diabetes. Though RBP4 could represent an early marker of insulin resistance, to date, none have determined RBP4 in SGA children. AIM Our aim was to measure RBP4 concentrations in cord blood of SGA newborns compared with those in children born with a birth weight appropriate for gestational age (AGA) and to determine whether serum RBP4 levels at birth correlate with insulin sensitivity markers. SUBJECTS AND METHODS Sixty-four newborns, 17 born SGA (mean gestational age: 36.4+/-2.1 weeks), and 47 born AGA (mean gestational age: 37.0+/-3.6 weeks) were studied. The main outcome measures included anthropometry, lipid profile, insulin, homeostasis model assessment, quantitative insulin-sensitivity check index, adiponectin, and RBP4. RESULTS RBP4 concentrations were significantly reduced in SGA newborns (p<0.002). No relationship was found between RBP4 and insulin sensitivity parameters. Stepwise regression analysis revealed that birth weight was the major predictor of RBP4 serum concentrations (p<0.001). CONCLUSION RBP4 is reduced in SGA newborns, birth weight representing the major determinant of RBP4 concentrations, and is not related to insulin sensitivity. No significant difference in adiponectin levels and insulin sensitivity markers was found between SGA and AGA neonates.

Abstract
We investigated in vitro apoptosis in human polymorphonuclear neutrophils (PMN) induced by omeprazole. This drug, both in the native (OM) and acidified (OM-HCl) form, is a potent inducer of PMN apoptosis. The effect is time- and dose-dependent. OM-HCl is more efficient than OM in inducing PMN apoptosis. In fact, after 24 h incubation in vitro at 1×10 −4M OM-HCl induces apoptosis in 70% of the cell population compared to 37% induced by OM. Apoptosis induced by both forms of the drug is caspase dependent being significantly reduced by pretreating cells with the caspase 3 inhibitor (DEVDH-CHO). However, some differences in the apoptosis mechanisms between the two forms of the drug seem to exist because PMN treatment with the specific caspase 8 inhibitor (Z-IETD-FMK) only blocks OM-HCl mediated apoptosis. We observed cleavage of caspase 8 only in the cells incubated with OM-HCl while the executioner caspase 3 was activated with both forms of the drug. Furthermore, pretreatment with GM-CSF, a known activator of intracellular survival pathways in PMN, partially protected cells from OM-HCl induced apoptosis but did not contrast the apoptotic effect of OM. Cysteine cathepsin proteases also seem involved in the apoptotic mechanism of both drug forms since the specific inhibitor E64d gave a significant protection. To verify if OM-HCl induced apoptosis was dependent on the sulfenamide bound with the cell sulfhydryl groups we used molecules with thiol groups such as β-mercaptoethanol (β-ME) and reduced glutathione (GSH). Reactions of OM-HCl with cellular sulfhydryl groups are strongly involved in both the triggering and evolving phase of the apoptotic mechanism since significant protection from apoptosis was obtained when PMN were pretreated for 1h with β-ME (lipid-permeable) or GSH (lipid-impermeable). These results show that OM and OM-HCl induce apoptosis in human PMN and suggest that the second binds the sulfhydryl groups, present on the cell membrane, to then penetrate the cell thus causing a further significant increase in apoptosis. OM-induced PMN apoptosis during the treatment of gastric inflammatory disease could be an advantage for the resolution of the phlogosis state. However, this aspect should be further elucidated to assess the optimal therapeutical regimen for gastric diseases which are related to infective agents.

Abstract
BACKGROUND Incisional hernia is a frequent complication of abdominal surgery (2-20% of all cases). Recurrence rate after simple repair without mesh is very high. The use of prosthetic materials has reduced the recurrences. Over the past decade, laparoscopic repair of incisional and umbilical hernias has become an interesting alternative to open procedure. PATIENTS AND METHODS The aim of this retrospective study was to evaluate efficacy, safety and advantages of laparoscopic approach in the treatment of incisional and umbilical hernias. From February 2000 through June 2006, a total of 127 incisional hernias (primary and recurrent), 21 umbilical and 19 epigastric hernias, were treated by laparoscopic approach. The exclusions for laparoscopy were: defect size less than 2 cm or more 20 cm, anesthesiologic problems, hemocoagulative disorders. The females/males ratio was 0/7, with a mean age of 59 years (range 24-83). The abdominal associated disease treated were 26. Three cases were treated as urgencies (strangulated hernias). RESULTS The conversion rate was 2 cases (1.2%). Mean operative time was 78 min (range 25-170). The mean postoperative hospital stay was 2.1 days (range: 1-5). The intra- and postoperative complication rate was 5% (above all seromas). The recurrence rate was 1.8% (3 cases). CONCLUSIONS More studies with long-term follow-up are necessary to prove the advantages of laparoscopic technique, but this large experience of more than 5 years, demonstrates that in selected cases the laparoscopic approach may be an interesting and effective alternative to open technique.

Abstract
AIM To assess at the scansion electron microscope (SEM) the structural aspects of enamel hypoplasia (EH) in coeliac disease (CD) with the aim to investigate our hypothesis of a possible significant difference between structural characteristics of EH in CD affected patients and EH of non-coeliac patients. If the presence of specific features of the EH associated with CD were demonstrated, these findings would represent for the dentist early non-invasive clinical markers of diagnosis of CD in case of suspected disease. METHODS We analysed at SEM two samples of enamel fragments from hypoplasic teeth, both deciduous and permanent, harvested from 10 coeliac children (18 permanent teeth, 6 deciduous teeth; study group) and 10 non-coeliac children (16 permanent teeth, 4 deciduous teeth; control group) treated for dental caries, dental extractions for extensive caries lesions or deciduous teeth exfoliation. RESULTS Significant structural differences were noted between EH of non-coeliac patients and same dental ? lesion in the group with CD. In the study group, EH defects were predominantly located on the central and lateral incisors, upper and lower, both deciduous and permanent, and on the first permanent molars, and were always simmetrical. EH of permanent teeth of CD affected patients was characterised by prisms more irregularly distributed with irregular margins and less interprismatic substance than observed in non-coeliac EH. The deciduous teeth of the study group showed shorter enamel prisms with a non-parallel direction up to convergence and less interprismatic substance than observed in the control group. CONCLUSION This morphological analysis at SEM of the hypoplasic enamel defects of a group of coeliac children, the first published in literature, demonstrates that the EH of deciduous and permanent teeth in CD is highly hypomineralised with shorter prisms, more irregularly distributed and less interprismatic substance than observed in the non-coeliac EH. More data are needed to validate the significance OF our observations with the aim to assess if this simple, non-invasive microscopic analysis can be considered effective for the early identification of silent cases of CD that otherwise would not be diagnosed in the paediatric age.

Abstract
AIM This paper addresses the need of the dental literature to document cases of Glycogen Storage Disease (GSD) type Ib with focus on the paediatric management of oral and dental problems and the potential complications arising from the increased susceptibility to bacterial infections, cariogenicity, and blood diathesis. METHODS Previous medical and dental papers on GSD type Ib published from 1980 to 2006 have been searched in the electronic databases PubMed and EMBASE using keywords of the NLM's Thesaurus, with the aim to retrieve important implications of treatment and preventive measures for an evidence-based multidisciplinary medical and dental management of the oral health problems of a 9-year old boy affected by GSD type Ib. CASE REPORT Oral and dental manifestations observed during a period of two years and relative treatments are reported from our case. Data on pharmacologic, oral hygienic, dietary, and surgical preventive measures for the control of recurrent oral infections, dental caries, gingival inflammation and risk of surgical bleeding are described. In addition, an electronic microscope structural analysis at SEM of the enamel tooth surface was conducted to identify any characteristic difference in the enamel architecture of this GSD type Ib affected patient compared with the normal enamel structure. CONCLUSION The oral manifestations of our case included uncommon findings such as multiple deep oral ulcers of the tongue, labial and vestibular mucosa, which could be related with a severe impairment of the neutrophil-related immune system of the patient. At SEM, the enamel of the deciduous teeth showed dark spots of hypomineralisation which are the first published data of an enamel-related susceptibility to dental caries. The quality of life of our patient increased thanks to the oral and dental treatments and preventive oral health measures given at clinical appointments. The dentist should be prepared to face the possible complications of surgery in these patients and the hospital setting seems to allow for this clinical safety.

Abstract
AIM Morbid obesity has increased its frequency in the last 20 years in association with the increase of a country's richness. Bariatric surgery has developed a role which is becoming more and more important. The aim of this study, after 10 years of experience with the biliopancreatic diversion, is to compare the laparoscopic versus open technique RESULTS METHODS From March 1993 to December 2004, 150 patients were operated by biliopancreatic diversion. We divided our experience into 2 groups: laparotomic and laparoscopic techniques. We compared the following variables in the 2 groups: total operating time, intestinal functions, postoperative pain, patient's discharge and recovery time, major postoperative complications, postoperative mortality, late complications, incisional hernia incidence and anastomotic ulceration. RESULTS We found a significant difference in both the reduction of the postoperative pain and the recanalization time in the laparoscopic group. Equally, we found a reduction in the incidence of abdominal wall complications, especially the reduction of incisional hernia and infections. The mean operative time was longer in the laparoscopic group, in particular due to the hard learning curve. CONCLUSIONS The laparoscopic biliopancreatic diversion is a feasible and safe operation with good results: less postoperative discomfort, shorter recanalization and ospedalization time, less incidence of abdominal wall morbidity (incisional hernia). However, the procedure may prove difficult and it needs a highly experienced surgeon in laparoscopic technique.

Abstract
Odontogenic fibroma (OF) is a rare benign odontogenic tumor deriving from the dental mesenchymal tissue and accounting for less than 5% of all odontogenic tumors. This paper presents an aggressive histologically diagnosed central odontogenic fibroma (COF) in a 17-year-old girl characterized by asymptomatic rapid growth with massive replenishment of the left maxillary sinus. We carried out a review of the literature to retrieve all published cases of COF especially focused on radiographic aspects and surgical treatment of cases characterized by clinical aggressive behaviour, as we observed in our patient. Search strategy included retrieval of English language papers, published from 1966 to today, in dental journals on MEDLINE/PubMed and EMBASE, and hand-searching of the bibliography of retrieved papers. Sixty-nine cases of COF were identified from 1954 to 2003 and a new one was added. We have compared characteristics of COFs according to age, gender, location, clinical and radiographic findings of aggressive development, and histology. We discuss clinical and radiographic aspects of our case compared with COFs previously published. We give suggestions for surgical treatment of COF in case of aggression to important anatomical structures.

Abstract
AIM About 2/3 of the Western population over the age of 80 years are affected by colic diverticulosis; 25% will develop diverticular disease with or without complications: fistula, obstruction, pericolic abscess, free perforation or hemorrhage. Laparoscopic approach for benign diseases of the colon such as diverticulosis, Chrohn's disease, etc. is unanimously considered as a very effective procedure. We have performed a retrospective analysis of 9 years with laparoscopic approach of the diverticular disease. The purpose of this study was to determine the feasibility, safety and benefits of laparoscopic approach. METHODS From May 1994 to November 2002, 69 patients affected by non-complicated diverticular disease, were treated laparoscopically, at the Mininvasive Surgery Department of Spoleto. In the same period other 213 patients suffering from cancer of the colon-rectum were operated through laparoscopic surgery. A colosigmoid resection with mesenteric inferior artery preservation was performed in 46 cases (67%). RESULTS We have performed only a laparoscopic colectomy technique (no hand-assisted procedures); the convertion rate was of 7.2%, the mean operative time was 145 min, no intraoperative complications were observed and finally the mean hospital stay was of 7.4 days (6-9). The postoperative complications were 1 case of infection of the umbilical scar and 1 case of pleural effusion with bronchopneumonia. CONCLUSIONS Elective laparoscopic colectomy for diverticular disease is feasible, safe and gives very good results: minimum postoperative discomfort, rapid recovery, low mobility and postoperative stay, rapid return to normal activities. However, in some cases, this procedure can be extremely difficult because of previous inflammatory complications (adhesions, fistulas or stenosis), therefore, high surgical skills in laparoscopic-colic surgery are required.

Abstract
BACKGROUND Breast tumour takes first place for frequency in women in Western Countries and is in constant increase. The diagnosis of the so-called non palpable lesions is increased remarkably above all due to the diffusion of mammographic screening and to a greater awareness of the problem. Furthermore it is helped by an important development of mininvasive diagnostic methods: the traditonal cytology with fine needle is supported by various trans-skin bioptic procedures (micro-histological examination). This methods almost always replaces the surgical excisional biopsy and frozen intraoperative examination, still used but reserved for particular cases. PATIENTS AND METHODS In our Department of General and Mininvasive Surgery, from December 1999 to September 2004, we carried out 214 biopsies, with the collaboration of the radiological Service, under echographic guidance using vacuum--assisted biopsy (Mammotome) with 11-Gauge needle. The results are examined and discussed here in this report with regard to diagnostic accuracy, quantity and quality of information, significant for subsequent surgical management. RESULTS Of 214 biopsies carried out with Mammotome technique, 89.3% of the cases are clinically non palpable lesions, with a average diameter of 8 mm. The average age of patients was 57.6 years (range 31-88). There are 90 cases of positive malignant pathology (42%). In the atypical ductal iperplasia and radial scar cases (6%) surgical removal of lesion was carried out which confirmed the previous bioptic diagnosis in 100% of cases. The 19% of patients submitted to a Mammotome biopsy was subject previously to cytology with fine needle. Comparing the results of both methods the diagnostic reliability of Mammotome was significantly superior (p < 0.05) as also the amount of information obtained (histotype, invasivity, grading, estrogen receptor, etc.); discomfort linked to the procedure, valued as pain (VAS), resulted inferior to the discomfort of biopsy with fine needle. The only complication of Mammotome biopsy is represented by haematoma in the biopsy site (8% of cases). The number of false negatives was one case due to incorrect targeting. CONCLUSION In the present situation, the choice of method is conditioned by the degree of radiological suspicion, taking into account the information obtained thereby, in order to ensure the appropriate surgise management. Mammotome biopsy of non palpable lesions of the breast, in our experience, is preferable if suspicion of malignancy is high. In this way a correct preoperative strategy can be prepared. Including the sentinel lymphnode method. Consequently a decision regarding the type of surgery can be taken (generally conservative), as well as making easier the intraoperative localisation of lesion by positioning the metallic clips during biopsy.
