Abstract
Since 1976 the Lombardy Cancer Registry (RTL) has recorded all malignant tumors and the benign tumors of the nervous system, bladder and liver occurring in the Varese province. The aims of this report are: to describe age-specific incidence rates of the different oncotypes of primary nervous system tumors (PNSTs) and to analyze the duration of survival of the patients according to the histotype of the neoplasm. From 1976 to 1981, the RTL recorded 498 PNST: 213 tumors of glial origin, 132 tumors of mesodermal tissues, 15 tumors of multipotential cell origin, 37 tumors of nerve roots, 8 of vascular origin, and 54 PNST in which the histotype was not specified. For tumors of glial origin, the 60–69 year age class showed the highest incidence rate: 16 per 100,000/year. The incidence rate of tumors of mesodermal tissues reached the maximum value of 7.9 per 100,000/year in the age group of 75 years and over. Tumors of multipotential cell origin had a maximum incidence of 2.2 in the 60–69 year age class. The probability of survival at 5 years after diagnosis was computed by the method of Kaplan and Meier (15), and the log rank procedure was used to test statistical differences among survivors. Tumors of glial origin, excluding ependymomas and papillomas of choroid plexus, had a 5-year survival probability of 14%. Age (categorized in ≤50 and > 50 years) and histologic grade (grades I+II and grades III+IV) were analyzed as prognostic factors for tumors of glial origin: a younger age was the most predictive prognostic factor in grade I+II tumors (probability of survival = 53% in the group ≤50 years vs 0 in the group > 50 years; p < 0.005). In the less differentiated tumors there were no differences between the two age groups. Patients with tumors of mesodermal tissues had a 5-year probability of survival of 83%. Subjects younger than 50 years had a probability of survival of 95%, whereas older patients had a probability of 79%. For the other oncotypes, the 5-year survival probability was: 50% for tumors of multipotential cell origin, 63% for ependymomas and papillomas of the choroid plexus, 64% for tumors of vascular derivation, and 21% for PNST with not specified histotype.

Abstract
Aims and Background The study describes the health status and the attainment of life goals in the adult survivors of childhood cancer recorded at the Childhood Cancer Registry of Piedmont. Methods and Study Design A postal questionnaire was sent to the general practitioner of the 690 cases born before 1976 and alive in 1991 after at least 5 years from diagnosis. The answer was received for 485 (72.9%) included in the analyses. Items in the questionnaire were: sequelae related to cancer and its treatment, health-related quality of life (according to Bloom's criteria), educational level attained, and employment status. Results Vital and marital status were obtained for all 690 cases at the offices of the town of residence. No medical condition was reported for 309 cases (63.7%). The overall proportion with a high school or university education was compared to corresponding figures for Piedmont in 1991, adjusted by age, and was as high as in the general population. Similar results are observed for occupation. Patients of both genders were married less than expected. Patients with leukemia (112 cases), non-Hodgkin's lymphoma (34) or Hodgkin's lymphoma (52) were reported to have the highest quality of life. In contrast, patients with tumors of the central nervous system (151) had the highest frequency of sequelae and the lowest score for health-related quality of life. They also presented the lowest educational achievement, the lowest proportion of employment and, among males, the lowest frequency of marriage. Conclusions Our study shows a good social adjustment of adult survivors from childhood cancer, with the exception of central nervous system tumors. From the methodologic point of view, the present study shows the feasibility of surveillance surveys on health-related quality of life with the contribution of general practitioners.

Abstract
Spirorchiids (family Spirorchiidae Stunkard 1921) are a group of flukes that inhabit the circulatory system of turtles. Infection by members of the family Spirorchiidae involves egg deposition in the host bloodstream and accumulation in tissues, which cause inflammatory reactions and embolisms, leading or contributing to the death of the host. Reports of spirorchiid egg lesions in loggerhead turtles ( Caretta caretta Linnaeus, 1758) have only been reported from U.S. hosts. In the present report a female loggerhead sea turtle was found dead on the beach in the north part of the State of Rio de Janeiro, Brazil. During gross necropsy, no parasite egg nodule was found. But the microscopic analysis revealed a mild granulomatous inflammatory process due to eggs from the family Spirorchiidae and both Langhans giant cells and foreign-body giant cells in the heart, kidneys, intestines, lungs, and spleen. The present note is the first record of tissue lesions due to spirorchiid eggs in a loggerhead sea turtle outside the United States.

Abstract
In joint arthroplasty one of the main issues related to the failure of prosthetic implants is due to the wear of the ultra-high molecular weight polyethylene (UHMWPE) component. Surface treatments and coatings have been recognized as enhancing methods, able to improve the tribological properties of the implants. Therefore, the main objective of this work was to investigate the possibility to fabricate yttria-stabilized zirconia (YSZ) coatings on a metal (AISI 316-L) substrate by means of Pulsed Electron Deposition, in order to improve the tribological behavior of the polymer-metal coupling, by reducing the initial wear of the UHMWPE component. In order to optimize the coating characteristics, the effects of working gas pressure on both its morphological and tribological properties were analyzed. Morphological characterization of the films was evaluated by Atomic Force Microscopy (AFM). Coating wettability was also estimated by contact angle (CA) measurement. Tribological performance (coupling friction and wear of UHMWPE) was evaluated by using a ball-on-disc tribometer during highly-stressing tests in dry and lubricated (i.e. NaCl and serum) conditions; friction and wear were specifically evaluated at the initial sliding distances - to highlight the main effect of coating morphology - and after 100m - where the influence of the intrinsic materials properties prevails. AFM analysis highlighted that the working pressure heavily affected the morphological characteristics of the realized films. The wettability of the coating at the highest and lowest deposition pressures (CA ~ 60°, closed to substrate value) decreased for intermediate pressures, reaching a maximum CA of ~ 90°. Regarding tribological tests, a strong correlation was found in the initial steps between friction coefficient and wettability, which decreased as the distance increased. Concerning UHMWPE wear associated to coated counterpart, at 100m a reduction rate of about 7% in dry, 12% in NaCl and 5% in presence of serum was obtained compared to the uncoated counterpart. Differently from what highlighted for friction, no correlation was found between wear rate and morphological parameters. These findings, in agreement with literature, underlined the effect of the deposition pressure on the morphological properties, but suggested that physical characteristics are influenced too. Further research on the deposition process will be required in order to improve the tribological performance of the coating at long distances, addressing - above all - orthopedic applications.

Abstract
OBJECTIVE Diverticular disease (DD) of the colon has an increasing burden on health services. The effectiveness of rifaximin for the treatment of DD, is not yet established. The aim of this study is to assess the impact of long-term treatment with rifaximin or mesalazine in a 10-day schedule for the prevention of recurrent diverticulitis. PATIENTS AND METHODS This is a retrospective study. We identified all consecutive patients with DD and previous acute diverticulitis (AD) in our outpatients' database; 124 patients, were included. The recommended therapy consisted of a ten-day/month treatment with either rifaximin (400 mg bid), or mesalazine (2.4 g/daily). Primary end point was AD recurrence. RESULTS Between 2010 and 2014, 72 patients were treated with rifaximin and 52 with mesalazine. During a median follow-up of 15 months (range 1-50), we observed 21 episodes of AD among users of either rifaximin (n=7; 0.54 per 100 person-months), or mesalazine group (n=14; 1.46 per 100 person-months). Kaplan-Meier survival estimates of recurrent AD significantly differed between rifaximin and mesalazine groups (p=0.015). The multivariate Cox regression analysis showed that AD recurrence was significantly associated with therapy (rifaximin vs. mesalazine, adjusted HR 0.27; 95% CI: 0.10 to 0.72), age and gender. CONCLUSIONS Long-term treatment with rifaximin in a 10-day schedule appears more effective than mesalazine in preventing recurrent AD.

Abstract
One of the most important issues leading to the failure of total joint arthroplasty is related to the wear of the plastic components, which are generally made of ultra high molecular weight polyethylene (UHMWPE). Therefore, the reduction of joint wear represents one of the main challenges the research in orthopedics is called to address nowadays. Surface treatments and coatings have been recognized as innovative methods to improve tribological properties, also in the orthopedic field. This work investigated the possibility to realize hard ceramic coatings on the metal component of a prosthesis, by means of Pulsed Plasma Deposition, in order to reduce friction and wear in the standard coupling against UHMWPE. Ti6Al4V substrates were coated with a 2 μm thick yttria-stabilized zirconia (YSZ) layer. The mechanical properties of the YSZ coatings were assessed by nanoindentation tests performed on flat Ti6Al4V substrates. Tribological performance was evaluated using a ball-on-disk tribometer in dry and lubricated (i.e. with fetal bovine serum) highly-stressing conditions, up to an overall distance of 10 km. Tribology was characterized in terms of coefficient of friction (CoF) and wear rate of the UHMWPE disk. After testing, specimens were analyzed through optical microscopy and SEM images, in order to check the wear degradation mechanisms. Progressive loading scratch tests were also performed in dry and wet conditions to determine the effects of the environment on the adhesion of the coating. Our results supported the beneficial effect of YSZ coating on metal components. In particular, the proposed solution significantly reduced UHMWPE wear rate and friction. At 10 km of sliding distance, a wear rate reduction of about 18% in dry configuration and of 4% in presence of serum, was obtained by the coated group compared to the uncoated group. As far as friction in dry condition is concerned, the coating allowed to maintain low CoF values until the end of the tests, with an overall difference of about 40% compared to the uncoated balls. In wet conditions, the friction values were found to be comparable between coated and uncoated materials, mainly due to a premature delamination of the coating. Scratch tests in wet showed in fact a reduction of the critical load required to a complete delamination due to a formation of blister, although no change or damage occurred at the coating during the soaking period. Although conditions of high values of contact pressure were considered, further analyses are however required to fully understand the behavior of YSZ coatings in wet environment and additional research on the deposition process will be mandatory in order to improve the coating tribological performance at long distances addressing orthopedic applications.

Abstract
BACKGROUND Autoimmune disease is one of the leading causes of morbidity and mortality worldwide. In Addison's disease, the adrenal glands are targeted by destructive autoimmunity. Despite being the most common cause of primary adrenal failure, little is known about its aetiology. METHODS To understand the genetic background of Addison's disease, we utilized the extensively characterized patients of the Swedish Addison Registry. We developed an extended exome capture array comprising a selected set of 1853 genes and their potential regulatory elements, for the purpose of sequencing 479 patients with Addison's disease and 1394 controls. RESULTS We identified BACH2 (rs62408233-A, OR = 2.01 (1.71-2.37), P = 1.66 × 10-15 , MAF 0.46/0.29 in cases/controls) as a novel gene associated with Addison's disease development. We also confirmed the previously known associations with the HLA complex. CONCLUSION Whilst BACH2 has been previously reported to associate with organ-specific autoimmune diseases co-inherited with Addison's disease, we have identified BACH2 as a major risk locus in Addison's disease, independent of concomitant autoimmune diseases. Our results may enable future research towards preventive disease treatment.

Abstract
DJ-1 mutations are associated to early-onset Parkinson's disease and accounts for about 1-2% of the genetic forms. The protein is involved in many biological processes and its role in mitochondrial regulation is gaining great interest, even if its function in mitochondria is still unclear. We describe a 47-year-old woman affected by a multisystem disorder characterized by progressive, early-onset parkinsonism plus distal spinal amyotrophy, cataracts and sensory-neural deafness associated with a novel homozygous c.461C>A [p.T154K] mutation in DJ-1. Patient's cultured fibroblasts showed low ATP synthesis, high ROS levels and reduced amount of some subunits of mitochondrial complex I; biomarkers of oxidative stress also resulted abnormal in patient's blood. The clinical pattern of multisystem involvement and the biochemical findings in our patient highlight the role for DJ-1 in modulating mitochondrial response against oxidative stress.

Abstract
Polymicrobial sepsis caused by cecal ligation and puncture (CLP) in mice produces the inflammatory and pathological sequelae of lung neutrophil infiltration, adult respiratory distress syndrome (ARDS) and death. These sequelae are dependent upon the synergistic interaction between several inflammatory mediators, including tumor necrosis factor (TNF), interleukin 1 (IL-1 ), and nitric oxide (NO). The overlapping spectrum of multiple mediator toxicity has hampered efforts to develop therapies for sepsis based on selective inhibition of a single mediator. Therefore, we tested the hypothesis that inhibition of multiple pro-inflammatory mediators would abrogate lethality. Our results show that administration of a tetravalent guanylhydrazone compound (CNI-1493) protected mice against 10 day mortality in CLP. Evidence of suppression of the cytokine cascade was given by decreased serum levels of TNF and IL-6 in CNI-1493 treated animals (TNF reduced 60% as compared to controls; IL-6 reduced 90% compared to controls; P < 0.05), and decreased levels of the acute-phase protein serum amyloid A response measured 24 h after CLP. Serum nitrites/nitrates, which give an index of NO production, were also significantly reduced (50%). Protection against CLP induced lung damage was observed as attenuation of edema and alveolar neutrophil infiltration, suppression of pulmonary TNF levels, and reduction of TUNEL-positive staining in lung. We conclude that CNI-1493 effectively inhibits the synthesis of multiple pro-inflammatory mediators and protects against death during polymicrobial sepsis.

Abstract
Despite complex interactions between obesity, dyslipidemia, hyperinsulinaemia, and the reproductive axis, the impact of metabolic syndrome on human male reproductive function has not been analysed comprehensively. Complete demographic, clinical, and laboratory data from 1337 consecutive primary infertile men were analysed. Health-significant comorbidities were scored with the Charlson Comorbidity Index (categorised 0 vs. 1 vs. 2 or higher). NCEP-ATPIII criteria were used to define metabolic syndrome. Semen analysis values were assessed based on the 2010 World Health Organisation (WHO) reference criteria. Descriptive statistics and logistic regression models tested the association between semen parameters and clinical characteristics and metabolic syndrome. Metabolic syndrome was found in 128 (9.6%) of 1337 men. Patients with metabolic syndrome were older (p < 0.001) and had a greater Charlson Comorbidity Index of 1 or higher (chi-square: 15.6; p < 0.001) compared with those without metabolic syndrome. Metabolic syndrome patients had lower levels of total testosterone (p < 0.001), sex hormone-binding globulin (p = 0.004), inhibin B (p = 0.03), and anti-Müllerian hormone (p = 0.009), and they were hypogonadal at a higher rate (chi-square: 32.0; p < 0.001) than patients without metabolic syndrome. Conversely, the two groups did not differ significantly in further hormonal levels, semen parameters, and rate of either obstructive or non-obstructive azoospermia. At multivariate logistic regression analysis, testicular volume (OR: 0.90; p = 0.002) achieved independent predictor status for WHO pathological semen concentration; conversely, age, Charlson Comorbidity Index scores, metabolic syndrome, and inhibin B values did not. No parameters predicted normal sperm morphology and total progressive motility. Metabolic syndrome accounts for roughly 9% of men presenting for primary couple's infertility. Although metabolic syndrome patients have a lower general male health status, semen analysis values seem independent of the presence of metabolic syndrome.

Abstract
The aim of this study was to evaluate plasma and synovial fluid concentrations of the non-steroidal anti-inflammatory drug nimesulide and its major metabolite (hydroxynimesulide, M1), after a single 100 mg dose of nimesulide and a repeated (14 day) administration, 100 mg twice a day, in patients with osteoarthritis of the knee and joint effusion. Nimesulide was rapidly absorbed in plasma and distributed in synovial fluid. On day 1, effective concentrations were present 30 min after the first dose and on day 14, the synovial fluid concentration of nimesulide was significantly higher than that measured on day 1; no accumulation was observed in plasma. After 14 days of treatment, both the plasma and synovial fluid concentrations of M1 were significantly higher than those measured on day 1. These data may help to explain the rapid onset of the analgesic effect of nimesulide demonstrated in several clinical conditions, including painful osteoarthritis.

Abstract
BACKGROUND Impulse Control Disorder symptoms (ICD) in Parkinson's disease (PD) has been recently associated by magnetic Resonance imaging with impaired cortico-striatal connectivity, especially between left putamen and frontal associative areas. METHODS 84 patients entered the study (21 PD-ICD+ and 64 PD-ICD-) and underwent DATSCAN imaging. The striatal tracer uptake was evaluated using BRASS software (Hermes, Sweden). The whole-brain analysis was performed with Statistical Parametric Mapping (SPM). RESULTS PD-ICD+ showed a significant reduction of left putaminal and left inferior frontal gyrus tracer uptake compared to PD-ICD-. Functional covariance analysis using left putamen as the seed point showed that, in contrast to ICD-patients, ICD+ patients had no functional covariance with contralateral basal ganglia and ipsilateral cingulate cortex, as index of an impaired inter- and intra-hemispheric dopamine binding in PD-ICD+. DISCUSSION the results support and expand the concept of a functional disconnection syndrome linked to ICD symptoms in PD patients through an asymmetric molecular frontostriatal network breakdown with left basal ganglia as central hub.
