Abstract
Flapping-wing micro air vehicles (FWMAVs) are a class of unmanned aircraft that imitate flight characteristics of natural organisms such as birds, bats, and insects, in order to achieve maximum flight efficiency and manoeuvrability. Designing proper mechanisms for flapping transmission is an extremely important aspect for FWMAVs. Compliant transmission mechanisms have been considered as an alternative to rigid transmission systems due to their lower the number of parts, thereby reducing the total weight, lower energy loss thanks to little or practically no friction among parts, and at the same time, being able to store and release mechanical power during the flapping cycle. In this paper, the state-of-the-art research in this field is dealt upon, highlighting open challenges and research topics. An optimization method for designing compliant transmission mechanisms inspired by the thoraxes of insects is also introduced.

Abstract
Fetal growth restriction (FGR) is a common and potentially severe pregnancy complication. Currently there is no treatment available. The guinea pig is an attractive model of human pregnancy as placentation is morphologically very similar between the species. Nutrient restriction of the dam creates growth-restricted fetuses while leaving an intact uteroplacental circulation, vital for evaluating novel therapies for FGR. Growth-restricted fetuses were generated by feeding Dunkin Hartley guinea pig dams 70% of ad libitum intake from four weeks before and throughout pregnancy. The effect of maternal nutrient restriction (MNR) on dams and fetuses was carefully monitored, and ultrasound measurements of pups collected. There was no difference in maternal weight at conception, however by five weeks post conception MNR dams were significantly lighter ( P < 0.05). MNR resulted in significantly smaller pup size from 0.6-0.66 gestation. Ultrasound is a powerful non-invasive tool for assessing the effect of therapeutic interventions on fetal growth, allowing longitudinal measurement of fetuses. This model and method yield data applicable to the human condition without the need for animal sacrifice and will be useful in the translation of therapies for FGR into the clinic.

Abstract
The present study was aimed at verifying the clinical characteristics of a typical attack in 20 migraine patients, 10 responders and 10 non-responders to rizatriptan, and at investigating any differences in the levels of neuropeptides of the trigeminovascular or parasympathetic systems [calcitonin gene-related peptide (CGRP), neurokinin A (NKA) and vasoactive intestinal peptide (VIP) measured by radio-immunoassay methods in external jugular blood] between responders and nonresponders. In all responders to rizatriptan, pain was unilateral, severe, and pulsating, and in five of them at least one sign suggestive of parasympathetic system activation was recorded. Five patients who were non-responders to rizatriptan referred bilateral and non-pulsating pain, even though severe in most of them. CGRP and NKA levels measured before rizatriptan administration were significantly higher in responders than in non-responders ( P < 0.0001 and P < 0.002, respectively). In the five patients with autonomic signs among rizatriptan responders, detectable VIP levels were found at baseline. One hour after rizatriptan administration, a decrease in CGRP and NKA levels was evident in the external jugular venous blood of rizatriptan responders, and this corresponded to a significant pain relief and alleviation of accompanying symptoms. VIP levels were also significantly reduced at the same time in the five patients with autonomic signs. After rizatriptan administration, CGRP and NKA levels in non-responder patients showed less significant variations at all time points after rizatriptan administration compared with rizatriptan responders. The present study, although carried out on a limited number of patients, supports recent clinical evidence of increased trigeminal activation associated with a better triptan response in migraine patients accompanied by parasympathetic activation in a subgroup of patients with autonomic signs. In contrast, the poor response seems to be correlated with a lesser degree of trigeminal activation, lower variations of trigeminal neuropeptides after triptan administration, and no evidence of parasympathetic activation at baseline.

Abstract
Purpose: To report our experience with the endovascular repair of iliac aneurysms secondary to aortoiliac bypass grafting. Methods: Thirteen patients (12 men; age range 62–86 years) with histories of aortoiliac reconstructions were treated with endovascular stent-grafts for 11 false and 2 true iliac aneurysms that averaged 5.2 cm in diameter (range 3.0–7.0). Via a percutaneous access and 9-F or 12-F sheaths, Passager or Wallgraft stent-grafts were delivered to exclude the aneurysms. Results: Twelve (92%) of 13 interventions were completed satisfactorily; 1 procedure for a true iliac aneurysm was converted to traditional bypass grafting. Two patients underwent additional surgical procedures. The average hospital stay for the patients with endovascular repairs only was 3 days (range 2–5). After a mean follow-up of 28 months (range 17–40), no complication or endoleak has been detected in any patient, and all endografts are patent. Conclusions: Endovascular repair is an effective treatment for secondary aneurysms arising after aortoiliac surgery. It is less invasive and involves a shorter hospital stay. Endovascular repair should be the first choice treatment for iliac aneurysms.

Abstract
A new penta(N-methylpyrrole carboxamide) analogue of the antibiotic distamycin has been synthesized in which the N-terminal formylamino group was replaced by a carbamoyl moiety. It was substantially more stable than distamycin in aqueous solution and bound to DNA with about the same affinity constant. It had an exemplary margin of selectivity against herpes simplex virus type 1-infected HEp-2 cells in culture compared to uninfected control cells, and was equipotent with distamycin. For comparison, data for analogues containing fewer N-methylpyrrole carboxamide units and/or lacking the carbamoyl replacement are presented. Extensive DNase I footprinting experiments were conducted and revealed that all the distamycin analogues bound to AT-rich nucleotide sequences in three different restriction fragments, irrespective of how many pyrrole rings or which terminal moiety they contained. However, the relative strength of footprints differed significantly among the various compounds, though the apparent size of the binding site did not. With semi-synthetic DNA containing inosine and 2,6-diaminopurine residues in place of guanosine and adenine, respectively, the compounds recognized new binding sites composed of IC-rich clusters and were excluded from binding to their canonical sites. This showed that the process of specific sequence recognition was critically dominated by the placement of the purine 2-amino group in the minor groove of the double helix.

Abstract
We report the case of a 39-year-old man with bilateral adrenal haemorrhage. The diagnosis is rarely primarily made with imaging alone. Our patient had a previous history of a stroke six years prior to this episode. We evoke the possibility that long-term daily cannabis use could be the underlying cause of the patient's vascular pathologies. After thorough review of existing literature, this link was found to be probable. Cannabis is the most consumed recreational drug in the world, and this tendency is ever-increasing. Serious complications other than psychiatric resulting from consumption are reported with increasing frequency. Neurological, cerebrovascular, cardiovascular and respiratory complications have been observed. It is thus important to remain vigilant when patients are hospitalised notably through the emergency department, in order to obtain a complete anamnesis, optimise screening, and to adapt the treatment of these patients.

Abstract
Abstract
The silicon tracker of the ATLAS experiment at CERN Large Hadron Collider will operate around –15°C to minimize the effects of radiation damage. The present cooling system is based on a conventional evaporative circuit, removing around 60 kW of heat dissipated by the silicon sensors and their local electronics. The compressors in the present circuit have proved less reliable than originally hoped, and will be replaced with a thermosiphon. The working principle of the thermosiphon uses gravity to circulate the coolant without any mechanical components (compressors or pumps) in the primary coolant circuit. The fluorocarbon coolant will be condensed at a temperature and pressure lower than those in the on-detector evaporators, but at a higher altitude, taking advantage of the 92 m height difference between the underground experiment and the services located on the surface. An extensive campaign of tests, detailed in this paper, was performed using two small-scale thermosiphon systems. These tests confirmed the design specifications of the full-scale plant and demonstrated operation over the temperature range required for ATLAS. During the testing phase the system has demonstrated unattended long-term stable running over a period of several weeks. The commissioning of the full scale thermosiphon is ongoing, with full operation planned for late 2015.

Abstract
Transmitted human immunodeficiency virus drug resistance in Europe is stable at around 8%. The impact of baseline mutation patterns on susceptibility to antiretroviral drugs should be addressed using clinical guidelines. The impact on baseline susceptibility is largest for nonnucleoside reverse transcriptase inhibitors. Background. Numerous studies have shown that baseline drug resistance patterns may influence the outcome of antiretroviral therapy. Therefore, guidelines recommend drug resistance testing to guide the choice of initial regimen. In addition to optimizing individual patient management, these baseline resistance data enable transmitted drug resistance (TDR) to be surveyed for public health purposes. The SPREAD program systematically collects data to gain insight into TDR occurring in Europe since 2001. Methods. Demographic, clinical, and virological data from 4140 antiretroviral-naive human immunodeficiency virus (HIV)–infected individuals from 26 countries who were newly diagnosed between 2008 and 2010 were analyzed. Evidence of TDR was defined using the WHO list for surveillance of drug resistance mutations. Prevalence of TDR was assessed over time by comparing the results to SPREAD data from 2002 to 2007. Baseline susceptibility to antiretroviral drugs was predicted using the Stanford HIVdb program version 7.0. Results. The overall prevalence of TDR did not change significantly over time and was 8.3% (95% confidence interval, 7.2%–9.5%) in 2008–2010. The most frequent indicators of TDR were nucleoside reverse transcriptase inhibitor (NRTI) mutations (4.5%), followed by nonnucleoside reverse transcriptase inhibitor (NNRTI) mutations (2.9%) and protease inhibitor mutations (2.0%). Baseline mutations were most predictive of reduced susceptibility to initial NNRTI-based regimens: 4.5% and 6.5% of patient isolates were predicted to have resistance to regimens containing efavirenz or rilpivirine, respectively, independent of current NRTI backbones. Conclusions. Although TDR was highest for NRTIs, the impact of baseline drug resistance patterns on susceptibility was largest for NNRTIs. The prevalence of TDR assessed by epidemiological surveys does not clearly indicate to what degree susceptibility to different drug classes is affected.

Abstract
In order to pass through the microcirculation, red blood cells (RBCs) need to undergo extensive deformations and to recover the original shape. This extreme deformability is altered by various pathological conditions. On the other hand, an altered RBC deformability can have major effects on blood flow and can lead to pathological implications. The study of the viscoelastic response of red blood cells to mechanical stimuli is crucial to fully understand deformability changes under pathological conditions. However, the typical erythrocyte biconcave shape hints to a complex and intrinsically heterogeneous mechanical response that must be investigated by using probes at the nanoscale level. In this work, the local viscoelastic behaviour of healthy and pathological red blood cells was probed by Atomic Force Microscopy (AFM). Our results clearly show that the RBC stiffness is not spatially homogeneous, suggesting a strong correlation with the erythrocyte biconcave shape. Moreover, our nanoscale mapping highlights the key role played by viscous forces, demonstrating that RBCs do not behave as pure elastic bodies. The fundamental role played by viscous forces is further strengthened by the comparison between healthy and pathological (diabetes mellitus) RBCs. It is well known that pathological RBCs are usually stiffer than the healthy ones. Our measures unveil a more complex scenario according to which the difference between normal and pathological red blood cells does not merely lie in their stiffness but also in a different dynamical response to external stimuli that is governed by viscous forces.

Abstract
BACKGROUND Intense physical stress might promote inflammatory responses, whereas a regular physical exercise has positive influence. Little is known on the acute metabolic and inflammatory responses to different levels of strenuous exercise in trained athletes. AIM To compare the short-term effect of two different ultra-endurance competitions on the inflammatory profile in male triathletes. METHODS We studied 14 Ironman (IR) and 13 Half Ironman (HIR) before and after their own specific race. We assessed body composition and measured blood cells, lipids, iron metabolism and plasma levels of some acute-phase cytokines and inflammatory markers. RESULTS After the race, IR showed reduced total body water and fat-free mass, not related with the duration of exercise, and increased white cells and platelets; high-density lipoprotein levels also increased. IR, but not HIR, showed reduced iron levels, increased ferritin and transferrin, reduced % saturated transferrin. HIR showed higher basal interleukin (IL)-6, tumour necrosis factor (TNF)-α, IL-10, IL-1β than IR; however, the post-performance rise was greater in IR. Irisin increased only in HIR and osteocalcin decreased in IR. In the whole study group, delta of white blood cells was directly related with delta of monocyte chemoattractant protein 1, and Δ ferritin was inversely related with Δosteocalcin. CONCLUSIONS A single ultra-endurance competition induces an inflammatory response depending on the duration of physical effort, with increased acute-phase cytokines, and an altered iron metabolism. Irisin, whose biological meaning is still uncertain, seems to be associated with acute variations of some metabolic parameters.

Abstract
AIM This study aims at investigating the possible relationships between anthropometric and functional parameters and maximal serve speed in professional tennis players. METHODS Eight professional male tennis players (age 23±4 [mean±SD] years; height 181±4 cm; body mass 80±4 kg; playing experience 14±4 years; weekly training practice 29±6 hours) were recruited. Anthropometric parameters (height, body mass, arm-racquet length, arm muscle area), jump performance (squat jump, counter movement jump; counter movement jump free), handgrip strength and first and second maximal serve speed were assessed. RESULTS Pearson's correlation coefficient showed significant (P<0.05) positive relationships between height and ball speed in both the first (r=0.78; P=0.02) and second (r=0.80; P=0.017) serve, and a significant negative correlation between serve speed and arm muscle area in first serve only (r=-0.78; P=0.03). In addition, a trend towards a positive correlation was observed between string tensions and serves speed for both first and second serves (r=0.54; P=0.16 and r=0.60; P=0.11, respectively). No significant relationship was found between serve speed and the other variables considered, including jumping performance parameters. CONCLUSION Height was confirmed to be the main anthropometric determinant of serves speed in professional tennis players.

Abstract
Cardio-facio-cutaneous (CFC) syndrome is a very rare and sporadic disease whose characteristics include dysmorphic facial appearance, ectodermal abnormalities, cardiac abnormalities, growth retardation and neurodevelopmental delay. This syndrome is classified as one of the RAS syndromes which are caused by altered signal transduction of the RAS/MAPK (mitogen activated protein kinase) pathway due to the mutation of genes including BRAF, MEK1/2, HRAS and KRAS. Other RAS syndromes, such as Costello syndrome and Noonan syndrome, share clinical features with CFC. Moreover, patients with the same clinical phenotype may have different molecular diagnoses. Clinical diagnosis is the starting pointfor correct classification. We describe the clinical data of one case of CFC syndrome, genetically determined by KRAS mutation, that involved chylothorax, lymphedema, sinus pericranii, craniosynostosis, and seizures. This is the second case report of the literature.

Obesity reduces the pro-angiogenic potential of adipose tissue stem cell-derived extracellular vesicles (EVs) by impairing miR-126 content: impact on clinical applications. Int J Obes (Lond) 2015; 40:102-11. [PMID: 26122028 PMCID: PMC4722244 DOI: 10.1038/ijo.2015.123] [Citation(s) in RCA: 86] [Impact Index Per Article: 9.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/20/2015] [Revised: 05/18/2015] [Accepted: 06/22/2015] [Indexed: 12/17/2022]
Abstract
BACKGROUND/OBJECTIVES Soluble factors and cell-derived extracellular vesicles (EVs) are crucial tissue repair mediators in cell-based therapy. In the present study, we investigate the therapeutic impact of EVs released by adipose tissue-derived stem cells (ASCs) recovered from obese subjects' visceral and subcutaneous tissues. METHODS ASCs were recovered from 10 obese (oASCs) and 6 non-obese (nASCs) participants and characterized. In selected experiments, nASCs and oASCs were cultured with palmitic acid (PA) or high glucose (HG), respectively. EVs from obese (oEVs) and non-obese (nEVs) subjects' visceral and subcutaneous ASCs were collected after ultracentrifugation and analyzed for their cargo: microRNA-126 (miR-126), vascular endothelial growth factor (VEGF), and matrix metalloproteinase 2 (MMP-2), and for their biological effects on endothelial cells (ECs). Western blotting analysis and loss- and gain-of function experiments were performed. RESULTS oEVs show impaired angiogenic potential compared with nEVs. This effect depends on EV cargo: reduced content of VEGF, MMP-2 and, more importantly, miR-126. We demonstrate, using gain- and loss-of-function experiments, that this reduced miR-126 content leads to Spred1 upregulation and the inhibition of the extracellular signal-regulated kinase 1/2 mitogen-activated protein kinase pathway in ECs. We also show that PA treatment of nASCs translates into the release of EVs that recapitulate oEV cargo. Moreover, HG treatment of oASCs further reduces miR-126 EV content and EV-mediated in vitro angiogenesis. Finally, impaired pro-angiogenic potential is also detected in EVs released from obese subcutaneous adipose tissue-derived ASCs. CONCLUSIONS These results indicate that obesity impacts on EV pro-angiogenic potential and may raise concerns about the use of adipose tissue-derived EVs in cell-based therapy in the obese setting.

Abstract
Usher syndrome is an autosomal recessive disorder characterized by retinitis pigmentosa, sensorineural hearing loss and, in some cases, vestibular dysfunction. The disorder is clinically and genetically heterogeneous and, to date, mutations in 11 genes have been described. This finding makes difficult to get a precise molecular diagnosis and offer patients accurate genetic counselling. To overcome this problem and to increase our knowledge of the molecular basis of Usher syndrome, we designed a targeted resequencing custom panel. In a first validation step a series of 16 Italian patients with known molecular diagnosis were analysed and 31 out of 32 alleles were detected (97% of accuracy). After this step, 31 patients without a molecular diagnosis were enrolled in the study. Three out of them with an uncertain Usher diagnosis were excluded. One causative allele was detected in 24 out 28 patients (86%) while the presence of both causative alleles characterized 19 patients out 28 (68%). Sixteen novel and 27 known alleles were found in the following genes: USH2A (50%), MYO7A (7%), CDH23 (11%), PCDH15 (7%) and USH1G (2%). Overall, on the 44 patients the protocol was able to characterize 74 alleles out of 88 (84%). These results suggest that our panel is an effective approach for the genetic diagnosis of Usher syndrome leading to: 1) an accurate molecular diagnosis, 2) better genetic counselling, 3) more precise molecular epidemiology data fundamental for future interventional plans.

Abstract
OBJECTIVE Perineal ultrasound has not yet been adequately evaluated in relation to the diagnosis of anatomical descensus of pelvic organs. Therefore, the aim of the present study was to assess whether it is possible to carry out a topographical comparison between bladders in normal seat and prolapsed ones and to quantify the extent of descensus. MATERIALS AND METHODS The authors selected 140 women, divided into three groups (two control groups and one case group). All patients underwent urogynaecological examination, according to the Pelvic Organ Prolapse Quantification (POP-Q), and perineal ultrasound to evaluate pubo-bladder distance. RESULTS Considering the data recorded in the two control groups, the authors established the physiological pubo-bladder distance between 27-33 mm at rest and 25-30 mm under stress. In the group with cystocele, the pubo-bladder distance was significantly lower: 20 mm at rest and three mm under stress (mean value). The authors also performed a classification of ultrasound cystocele in four stages, in accordance with clinical staging. CONCLUSIONS In conclusion, the present data show the excellent potential role of perineal ultrasound in the diagnosis of cystocele, but it is necessary to perform randomized studies to standardize the method.

Abstract
This study investigated the involvement of proteasome and macrophages M2 in the protection afforded by telmisartan against the acute myocardial infarction in Zucker diabetic fatty (ZDF) rats with metabolic syndrome. ZDF rats were treated for three weeks with telmisartan at doses of 7 and 12 mg/kg/day. After treatment, rats were subjected to a 25 min occlusion of the left descending coronary artery followed by 2 h reperfusion (I/R). At the end of the I/R period, biochemical, immunohistochemical, and echocardiographic evaluations were done. Telmisartan treatment (7 mg/kg and 12 mg/kg) reduced the myocardial infarct size, the expression of proteasome subunits 20S and 26S, and the protein ubiquitin within the heart. The compound has led to an increased M2 macrophage phenotype within the cardiac specimens and a modification of the cardiac cytokine and chemokine profile. This was functionally translated in improved cardiac performance as evidenced by echography after 2 h reperfusion. 7 mg/kg/day telmisartan was sufficient to improve the left ventricular ejection fraction LVEF of the rat heart recorded after I/R (e.g., vehicle 38 ± 2.2%; telmisartan 54 ± 2.7%) and was sufficient to improve the diastolic function and the myocardial performance index up to values of 0.6 ± 0.01 measured after I/R.

Abstract
To assess the rate of sexual distress, sexual dysfunction and relationship quality and their association with clinical variables in women with systemic sclerosis (SSc), 102 sexually active women with SSc were recruited. Sexual distress, sexual dysfunction and dissatisfaction with relationship quality were investigated by Female Sexual Distress Scale Revised (FSDS-R), Female Sexual Function Index (FSFI) and Dyadic Adjustment Scale (DAS), respectively. The patients underwent medical examinations and nailfold videocapillaroscopy (NVC). Of the 102 patients, 37 (36%) reported sexual distress with FSDS-R score >11, 45 (44%) had sexual dysfunction with FSFI score <19 and 49 (48%) were not satisfied with relationship quality with DAS score <100. There was a negative correlation (p<0.001, R= −0.30) between FSDS-R and FSFI. No correlation was found between FSDS-R and DAS. FSFI showed a positive correlation with DAS (p<0.0001, R= 0.36). Age correlated negatively (p<0.05, R= −0.26) with FSFI, while FSDS-R and DAS did not correlate (p>0.05) with age. SSc women with digital ulcers (DU) had a reduction of FSFI and DAS compared with women without DU. In patients with late capillaroscopic pattern, mean value of FSFI was significantly lower than the other two capillaroscopic patterns. DAS decreased with progression of capillaroscopic damage. In a high percentage of women with SSc FSDS-R was increased, while FSFI and DAS were reduced. Age correlated negatively with FSFI, while skin score showed a negative correlation with DAS. Digital vascular damage negatively influenced FSFI and DAS.

Abstract
BACKGROUND The preoperative assessment involves the process of evaluating the patient's clinical condition, which is intended to define the physical status classification, eligibility for anesthesia and the risks associated with it, thus providing elements to select the most appropriate and individualized anesthetic plan. The aim of this recommendation was provide a framework reference for the preoperative evaluation assessment of pediatric patients undergoing elective surgery or diagnostic/therapeutic procedures. METHODS We obtained evidence concerning pediatric preoperative evaluation from a systematic search of the electronic databases MEDLINE and Embase between January 1998 and February 2012. We used the format developed by the Italian Center for Evaluation of the Effectiveness of Health Care's scoring system for assessing the level of evidence and strength of recommendations. RESULTS We produce a set of consensus guidelines on the preoperative assessment and on the request for preoperative tests. A review of the existing literature supporting these recommendations is provided. In reaching consensus, emphasis was placed on the level of evidence, clinical relevance and the risk/benefit ratio. CONCLUSION Preoperative evaluation is mandatory before any diagnostic or therapeutic procedure that requires the use of anesthesia or sedation. The systematic prescription of complementary tests in children should be abandoned, and replaced by a selective and rational prescription, based on the patient history and clinical examination performed during the preoperative evaluation.

Abstract
The purpose of the study is to examine the incidence of adverse reactions caused by non-ionic contrast media in selected patients after desensitization treatment and to evaluate the safety profile of organ iodine contrast media (i.c.m.) in a multistep prevention protocol. In a population of 2000 patients that had received a CT scan, 100 patients with moderate/high risk for adverse reactions against iodinated contrast agents followed a premedication protocol and all adverse reactions are reported and classified as mild, moderate or severe. 1.7 percent of the pre-treated patients reported a mild, immediate type reaction to iodine contrast; of these five patients with allergy 0.71 percent had received iomeprol, 0.35 percent received ioversol and 0.71 percent received iopromide. The incidence of adverse reactions was reported to be higher (4 out of 5 patients) among those that referred a history of hypersensitivity against iodinated i.c.m. Although intravenous contrast materials have greatly improved, especially in terms of their safety profile, they should not be administered if there isn't a clear or justified indication. In conclusion, even if we know that the majority of these reactions are idiosyncratic and unpredictable we propose, with the aim of improving our knowledge on this subject, a multicenter study, based on skin allergy tests (prick test, patch test, intradermal reaction) in selected patients that have had previous experiences of hypersensitivity against parenteral organ iodine contrast media.

Abstract
INTRODUCTION Pulmonary localized forms of Waldenström's macroglobulinemia are rare. CASE REPORT We report the observation of a 71-year-old woman with chronic cough and persisting alveolar opacities after several courses of antibiotics. Physical examination was unremarkable. Protein electrophoresis identified a monoclonal IgM in the serum. The lymphocyte immunophenotyping from the bronchoalveolar lavage was consistent with a B-cell lymphoma and Waldenström's macroglobulinemia was confirmed by the bone marrow biopsy. Chemotherapy with a combination of rituximab, fludarabine and cyclophosphamide improved the patient's symptoms and caused the pulmonary opacities to resolve. We discuss the various clinical and radiological pulmonary manifestations of this slowly progressive hematological condition. CONCLUSION Pulmonary manifestations of Waldenström's macroglobulinemia result in various clinical and radiological patterns. A serum protein electrophoresis should be performed in cases of pleuropulmonary opacities persisting despite antibiotics.

Abstract
OBJECTIVE Innate and adaptive immunity may contribute to gland dysfunction in patients with primary Sjögren's syndrome (pSS). The P2X7 receptor (P2X7 R)-NLRP3 inflammasome complex modulates the release of the inflammatory cytokines IL-1β and IL-18. The presence of P2X7 R in salivary glands suggests an interesting scenario for the initiation and amplification of the innate immune response in pSS. Therefore, the aim of this study was to assess the role of the P2X7 R-NLRP3 inflammasome in pSS. SUBJECTS AND METHODS Twenty-one consecutive patients with pSS according to the American-European Consensus Group criteria and 15 patients with sicca syndrome (i.e. without Sjögren's syndrome, non-SS) were enrolled in this study, together with six control (CTL) subjects. Expression of the P2X7R-NLRP3 platform and IL-18 was determined by real-time PCR and western blotting in gland specimens and peripheral lymphomonocytes; data were related to patients\x92 clinical, serological and histopathological characteristics. The presence of IL-18 was determined in gland and saliva samples. RESULTS P2X7 R expression was significantly higher in salivary glands from individuals with pSS than in those from non-SS and CTL subjects. Accordingly, the gene expression levels of the inflammasome components NLRP3, ASC and caspase-1 were significantly higher in pSS gland specimens, and this was paralleled by an increased expression of mature IL-18 in pSS saliva samples. The expression of both the P2X7 R and the inflammasome components was a marker of disease-related glandular involvement, being increased in patients with anti-Ro/SSA positivity and correlated with focus score. CONCLUSION The results of this study suggest an involvement of the P2X7 R-inflammasome-caspase-1-IL-18 axis in the development of pSS exocrinopathy. This finding provides the basis for studying the complex mechanisms underlying pSS, as well as for developing novel potential therapeutic strategies.

Abstract
WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT Obesity is an increasingly prevalent metabolic disorder and it is associated with a large number of comorbidities, including cardiovascular diseases. Adipose tissue is an active endocrine organ and its ectopic depots and distribution have different metabolic meanings on risks for health; as a matter of fact, epicardial fat seems to play a specific role in cardiovascular diseases. The use of dual-energy X-ray absorptiometry (DXA) to evaluate and follow-up patients affected by obesity is becoming a very important point in the management of the disease. WHAT THIS STUDY ADDS An investigation of the association between epicardial fat and regional adiposity by DXA in female obese patients. The total amount of central (trunk) fat mass is more strongly correlated than android visceral fat mass to epicardial thickness in obese women. In the interpretation of whole-body DXA data, physician should consider trunk fat mass for good and independent predictivity on epicardial fat depots. Our aim was to analyse in a population of obese women the relationship between the amount of epicardial fat as measured by transthoracic echocardiography (US) and the parameters of regional adiposity by dual-energy X-ray absorptiometry (DXA), with particular reference to a new software for visceral fat assessment and to a new 'heart-suited' regions of interests (ROIs). Sixty patients who satisfied technical inclusion criteria underwent whole-body DXA scan and US on the same day. Total and android fat mass (FM) and FM percentage (FM%) were considered as well as visceral fat (VAT) subcompartment in the android region; moreover, six new ROIs were designed on whole-body DXA images for the investigation of adiposity parameters at heart level. US provided epicardial fat thickness (EPI-thickness) and area (EPI-area), as measured following previously validated methods. Body mass index (BMI), gynoid and lower limbs (FM and FM%) were found not statistically correlated with EPI-thickness. The highest correlation was achieved by trunk FM (and FM%, with r = 0.544 and 0.480 respectively, P < 0.001), followed by ROI-1 FM (ROI-1 was drawn following thoroughly the cardiac profile), and android FM. Multivariate analysis including age, weight, BMI, trunk FM and the new ROIs (added one by one), retained in the final model trunk FM. Correlations of DXA with EPI-area were superimposable. In obese women, VAT or other new-designed ROIs are not better correlated than traditional ROIs (i.e. trunk) with epicardial fat amount.

Abstract
The aims of this study are to determine the frequency of diagnosis of atypical lobular hyperplasia (ALH) and lobular carcinoma in situ (LCIS) at stereotaxic-guided 11-gauge vacuum-assisted breast biopsy (VABB) and to assess the rate of underestimation of these at subsequent surgical excision and follow-up. Moreover, we aimed to define clinical, radiological and histological features of nonpalpable lesions in core biopsies that predict the lesion upgrade. Retrospective review of 11-gauge VABB was performed to identify the underestimation rate of nonpalpable lesions diagnosed as ALH or LCIS at VABB. Thirteen cases of ALH and 36 cases of LCIS were sent to surgery, 29 cases of ALH and 14 cases of LCIS were sent to follow-up. The clinical, mammographic and histologic features were assessed. The correlation between mammographic BI-RADS score and histological B-classification for both ALH and LCIS lesions were performed by Pearson's test. Of 1,765 patients enrolled, lobular lesions (ALH and/or LCIS) occurred in 82 cases, and underestimation arose in 9 (10.9%). Two cases of underestimated ALH were upgraded to invasive lobular carcinoma and one to invasive ductal carcinoma. One case of underestimated LCIS was upgraded to ductal carcinoma in situ, two to invasive ductal carcinoma and three to invasive lobular carcinoma. The histology of the core and surgical specimens were compared. A significant difference was seen in the BI-RADS score (4–5 in 91% of underestimated lesions), and the size of the lesions (≥ 1.5 cm) for underestimated cases versus accurately diagnosed cases (p<0.001). Further significant parameters predictive for malignancy were the incomplete lesion removal by VABB and the presence of associated different breast lesions in the specimen. In conclusion, as far as ALH is concerned, we propose surgery as first choice when at least one of the following condition is respected: positive history for breast carcinoma, lesion >1.5cm, co-presence of high-risk lesions in the sample, signs of ductal involvement, high histological grading for atypia and follow-up in the other cases. Surgery is recommended in all cases of LCIS:

Abstract
Ankle fractures account for 9 % of fractures (Clare in Foot Ankle Clin 13(4):593-610, 1) representing a significant portion of the trauma workload; proximal femoral fractures are the only lower limb fracture to present more frequently. Ankle fractures have a bimodal age distribution with peaks in younger males and older females (Arimoto and Forrester in AJR Am J Roentgenol 135(5):1057-1063, 2). There has been threefold increase in the incidence among elderly females over the past three decades (Haraguchi and Armiger in J Bone Joint Surg Am 91(4):821-829, 3). In 1950, Lauge-Hansen devised a classification of ankle fractures based on the position of the foot and the deforming force at the time of injury. This has been widely accepted by orthopedists, but is not in general use by radiologists. Identification of the fractures and classification of the type of injury allows diagnosis of the otherwise occult ligamentous injuries. Three radiographic views of the ankle (anteroposterior, mortise, and lateral) are necessary to classify an injury with the Lauge-Hansen system. Two additional criteria are also necessary: the position of the foot at the time of injury and the direction of the deforming force.

Abstract
Pelvic floor disorders represent a significant cause of morbidity associated with a severe reduction of quality of life. It represents a very common clinical problem that afflicts women three to seven time more often than men. The purpose of this study was to assess the diagnostic tools available to define the imaging strategy in patients with pelvic floor dynamic dysfunctions and to investigate their abilities in the diagnosis of enterocele, elytrocele and edrocele. From January 2008 to May 2011, 614 patients with symptoms related to pelvic floor dynamic dysfunctions were enrolled in our retrospective study. After anamnesis and clinical examination, entero-colpo-defecography (ECD) and supine entero-magnetic resonance (SE-MR) exams were performed in all patients. This study showed that the diagnostic efficacy of ECD is higher than that of SE-MR in the detection of enterocele and edrocele. Furthermore, elytrocele can be visualized only with ECD considering the position of patient during SE-MR examination. In addition, in patients planned for surgery, SE-MR is more useful to clarify the intra-pelvic interaction of multiple organ prolapse and to better define the pelvic anatomy and functioning.
