Abstract
AIM We suggest a numerical method for the preoperative assessment of difficulty in mandibular third molar surgeries. METHODS This study enrolled 1000 subjects ranging in, age from 17 to 91 years, who presented to the Clinic of Maxillary Facial Surgery at the, University of Florence in Italy, for impacted mandibular third molars removal in 2013. The difficulty of extraction was analyzed for each patient. RESULTS Comparison of preoperative difficulty assessment scores with the actual difficulty encountered by an operator, confirming the reliability of our protocol. CONCLUSION Careful preoperative analysis of the extraction difficulties and correct surgical planning can reduce intra and postoperative complications, in the third impacted mandibular molar surgeries. The use of an easy and rapid method for the assessment of difficulty in third molar surgeries, is an efficient clinical methodology for preoperative analysis.

Abstract
Growing evidence links adverse prenatal conditions to mood disorders. We investigated the long-term behavioral alterations induced by prenatal exposure to excess glucocorticoids (dexamethasone--DEX). At 12 months, but not earlier, DEX-exposed mice displayed depression-like behavior and impaired hippocampal neurogenesis, not reversible by the antidepressant fluoxetine (FLX). Concomitantly, we observed arrhythmic glucocorticoid secretion and absent circadian oscillations in hippocampal clock gene expression. Analysis of spontaneous activity showed progressive alterations in circadian entrainment preceding depression. Circadian oscillations in clock gene expression (measured by means of quantitative PCR) were also attenuated in skin fibroblasts before the appearance of depression. Interestingly, circadian entrainment is not altered in a model of depression (induced by methylmercury prenatal exposure) that responds to FLX. Altogether, our results suggest that alterations in circadian entrainment of spontaneous activity, and possibly clock gene expression in fibroblasts, may predict the onset of depression and the response to FLX in patients.

Abstract
Developmental exposure to excess glucocorticoids (GCs) has harmful neurodevelopmental effects, which include persistent alterations in the differentiation potential of embryonic neural stem cells (NSCs). The mechanisms, however, are largely unknown. Here, we investigated the effects of dexamethasone (Dex, a synthetic GC analog) by MeDIP-like genome-wide analysis of differentially methylated DNA regions (DMRs) in NSCs isolated from embryonic rat cortices. We found that Dex-induced genome-wide DNA hypomethylation in the NSCs in vitro. Similarly, in utero exposure to Dex resulted in global DNA hypomethylation in the cerebral cortex of 3-day-old mouse pups. Dex-exposed NSCs displayed stable changes in the expression of the DNA methyltransferase Dnmt3a, and Dkk1, an essential factor for neuronal differentiation. These alterations were dependent on Tet3 upregulation. In conclusion, we propose that GCs elicit strong and persistent effects on DNA methylation in NSCs with Tet3 playing an essential role in the regulation of Dnmt3a and Dkk1. Noteworthy is the occurrence of similar changes in Dnmt3a and Dkk1 gene expression after exposure to excess GC in vivo.

Abstract
The aim of this study was to compare the immediate and long-term effect of a cognitive-behavior therapy program for anorexia nervosa inpatients with and without concomitant Major Depressive Episodes (MDE). The program has been adapted from the "enhanced" form of Cognitive Behavior Therapy (CBT) for eating disorders. Sixty-three consecutive underweight adult patients with severe eating disorder were treated with inpatient CBT. MDE was assessed with the structured clinical interview for DSM-IV. The Eating Disorder Examination, and the Brief Symptom Inventory were recorded at entry, at the end of treatment, and 6 and 12 months later. MDE was present in 60.3% of participants. No significant differences were observed in the demographic and baseline clinical variables between patients with and without MDE. Significant improvements in weight, and in eating disorder and general psychopathology were showed. There were no differences between participants with and without MDE in terms of treatment outcome, and the severity of depression was not associated with changes in global Eating Disorder Examination score. These findings suggest that a diagnosis of MDE does not influence the outcome of inpatient treatment for anorexia nervosa patients, and that the severity of depression cannot be used to predict the success or failure of such treatment.

Abstract
Prostate cancer, one of the most common forms of cancer among men, can benefit from recent improvements in positron emission tomography (PET) technology. In particular, better spatial resolution, lower noise and higher detectability of small lesions could be greatly beneficial for early diagnosis and could provide a strong support for guiding biopsy and surgery. In this article, the impact of improved PET instrumentation with superior spatial resolution and high sensitivity are discussed, together with the latest development in PET technology: resolution recovery and time-of-flight reconstruction. Using simulated cancer lesions, inserted in clinical PET images obtained with conventional protocols, we show that visual identification of the lesions and detectability via numerical observers can already be improved using state of the art PET reconstruction methods. This was achieved using both resolution recovery and time-of-flight reconstruction, and a high resolution image with 2 mm pixel size. Channelized Hotelling numerical observers showed an increase in the area under the LROC curve from 0.52 to 0.58. In addition, a relationship between the simulated input activity and the area under the LROC curve showed that the minimum detectable activity was reduced by more than 23%.

Abstract
Transcatheter aortic valve implantation (TAVI) is a minimally invasive procedure introduced to treat aortic valve stenosis in elder patients. Its clinical outcomes are strictly related to patient selection, operator skills, and dedicated pre-procedural planning based on accurate medical imaging analysis. The goal of this work is to define a finite element framework to realistically reproduce TAVI and evaluate the impact of aortic root anatomy on procedure outcomes starting from two real patient datasets. Patient-specific aortic root models including native leaflets, calcific plaques extracted from medical images, and an accurate stent geometry based on micro-tomography reconstruction are key aspects included in the present study. Through the proposed simulation strategy we observe that, in both patients, stent apposition significantly induces anatomical configuration changes, while it leads to different stress distributions on the aortic wall. Moreover, for one patient, a possible risk of paravalvular leakage has been found while an asymmetric coaptation occurs in both investigated cases. Post-operative clinical data, that have been analyzed to prove reliability of the performed simulations, show a good agreement with analysis results. The proposed work thus represents a further step towards the use of realistic computer-based simulations of TAVI procedures, aiming at improving the efficacy of the operation technique and supporting device optimization.

Abstract
BACKGROUND Late sequelae of septic arthritis of the glenohumeral joint are very rare and represent a potentially devastating condition that can result in irreversible changes at the level of joint and surrounding soft tissues. MATERIALS AND METHODS Between January 2001 and December 2010, ten patients were treated at our institution for late sequelae of septic arthritis of the shoulder. There were eight men and two women with a mean age of 67.9 years (range 62-74 years). Eight of ten patients had previously received three or more intra-articular or subacromial injections. Surgical treatment consisted of open joint debridement, humeral head resection and implantation of an antibiotic spacer followed by a 6-8-week course of intravenous antibiotics. RESULTS White blood cell count, C-reactive protein and erythrocyte sedimentation rate normalized between 6 and 8 weeks postoperatively in all patients. No recurrent infection was observed in any patient. Postoperatively, the mean Constant score was 37 (range 28-46) and mean DASH score was 54 (range 40-69), demonstrating a very limited function in these patients. There was a trend toward improved outcome scores in patients who underwent early surgical debridement. Five patients underwent delayed reconstruction with a reverse shoulder prosthesis, and at minimum 1-year follow-up, the mean Constant score was 56 (range 47-69) and mean DASH score was 33 (31-38). CONCLUSIONS Antibiotic spacers are able to deliver antibiotics locally to the infected tissue while reducing the dead space and stabilizing the glenohumeral joint. An early, aggressive management of the infection is essential to maximize clinical outcomes and avoid either significant destruction or ankylosis of the shoulder joint.

Abstract
INTRODUCTION Inpatient treatment for anorexia nervosa is often successful in restoring body weight, but a high percentage of patients relapse following discharge. The aim of the present study was to establish the immediate and longer-term effects of a novel inpatient program for adolescents that was designed to produce enduring change. METHOD Twenty-seven consecutive patients with severe anorexia nervosa were admitted to a 20-week inpatient treatment program based on the enhanced cognitive behavior therapy (CBT-E). The patients were assessed before and after hospitalization, and 6 and 12 months later. RESULTS Twenty-six patients (96%) completed the program. In these patients, there was a substantial improvement in weight, eating disorder features, and general psychopathology that was well maintained at 12-month follow-up. CONCLUSION These findings suggest that inpatient CBT-E is a promising approach to the treatment of adolescents with severe anorexia nervosa.

Abstract
They're flexible and sticky: While investigations of the very stiff DNA molecular conformation on surfaces have been made, the equivalent for more typical macromolecules is complicated by their shorter persistance length. A gentle detachment study with a polymer bound to an SFM tip allows the forces between the polymer and surface to be probed; the detachement force required depends on the surface conformation, whether only a small loop or a long tail must be peeled from the surface, as shown by the cartoon.

Abstract
BACKGROUND The aim of this study was to compare the immediate and longer-term effects of two cognitive behaviour therapy programmes for hospitalized patients with anorexia nervosa, one focused exclusively on the patients' eating disorder features and the other focused also on mood intolerance, clinical perfectionism, core low self-esteem or interpersonal difficulties. Both programmes were derived from enhanced cognitive behaviour therapy (CBT-E) for eating disorders. METHODS Eighty consecutive patients with severe anorexia nervosa were randomized to the two inpatient CBT-E programmes, both of which involved 20 weeks of treatment (13 weeks as an inpatient and 7 as a day patient). The patients were then followed up over 12 months. The assessments were made blind to treatment condition. RESULTS Eighty-one percent of the eligible patients accepted inpatient CBT-E, of whom 90% completed the 20 weeks of treatment. The patients in both programmes showed significant improvements in weight, eating disorder and general psychopathology. Deterioration after discharge did occur but it was not marked and it was restricted to the first 6 months. There were no statistically significant differences between the effects of the two programmes. CONCLUSIONS These findings suggest that both versions of inpatient CBT-E are well accepted by these severely ill patients and might be a viable and promising treatment for severe anorexia nervosa. There appears to be no benefit from using the more complex form of the treatment.

Abstract
Finite element analysis is nowadays a well-assessed technique to investigate the impact of stenting on vessel wall and, given the rapid progression of both medical imaging techniques and computational methods, the challenge of using the simulation of carotid artery stenting as procedure planning tool to support the clinical practice can be approached. Within this context, the present study investigates the impact of carotid stent apposition on carotid artery anatomy by means of patient-specific finite element analysis. In particular, we focus on the influence of the vessel constitutive model on the prediction of carotid artery wall tensional state of lumen gain and of vessel straightening. For this purpose, we consider, for a given stent design and CA anatomy, two constitutive models for the CA wall, that is, a hyperelastic isotropic versus a fiber-reinforced hyperelastic anisotropic model. Despite both models producing similar patterns with respect to stress distribution, the anisotropic model predicts a higher vessel straightening and a more evident discontinuity of the lumen area near the stent ends as observed in the clinical practice. Although still affected by several simplifications, the present study can be considered as further step toward a realistic simulation of carotid artery stenting.
