Abstract
Peripheral neutrophils (PMN) are a useful model to study cell activation and to evaluate the multiple stressors' interference with signalling pathways. This study aimed to evaluate the effects of different exposure to noxious agents on PMN activity by chemiluminescence assays. Two groups of office workers were recruited: peripheral whole blood cells and isolated PMNs were analyzed, performing intra- and extra-cellular chemiluminescence evaluation to study compartmental release of radical species. The exposed group shows a higher emission in resting whole blood chemiluminescence than in controls; the intracellular chemiluminescence emission in urban employees was increased, whereas the extracellular was not affected. After stimulation, the extracellular chemiluminescence was decreased in urban employees, whereas the intracellular emission did not show differences. We hypothesize that once stimulated, exposed subjects' PMNs respond to stimuli less than unexposed: PMNs could be considered indicators of chronic exposure to noxious agents.

Abstract
BACKGROUND Unlike chronic idiopathic intestinal pseudo-obstruction (CIIP), severe digestive syndromes that are not characterized by episodes resembling mechanical obstruction remain poorly characterized. The present study compared clinical features, small bowel motility, and quality of life (QoL) in patients with CIIP or severe functional gastrointestinal disorders (SFGID), compared to irritable bowel syndrome (IBS). METHODS We enrolled 215 consecutive patients: 70 CIIP, 110 malnourished SFGID [body mass index (BMI) 17.8±1.8kg m(-2) ] and 35 non-malnourished SFGID (BMI 22.8±3.6kgm(-2) ). KEY RESULTS Abnormal motor patterns that fulfilled diagnostic criteria for small bowel dysmotility were virtually absent in IBS patients, but were recorded in69 CIIP patients (98.6%), 82 malnourished SFGID patients (74.5%;), and 23 SFGID patients without malnutrition (65.7%) (P<0.0001). CIIP patients presented more frequently abnormal activity fronts, lack of response to feeding, and hypomotility than malnourished and non-malnourished SFGID patients (61.4%vs 42.7% and 31.4%, P<0.05 only vs non-malnourished SFGID; 8.6%vs 0.9% and 2.9%; 21.4%vs 0.9% and 0%, P<0.05). Quality of life mean scores were all significantly lower in CIIP patients and malnourished SFGID patients than in IBS. Bodily pain, general health, and vitality scores were lower in CIIP also compared to non-malnourished SFGID. CONCLUSIONS & INFERENCES Chronic idiopathic intestinal pseudo-obstruction and SFGIDs are frequently associated with small bowel dysmotility and marked derangements of QoL which are significantly more severe than in IBS and result particularly in being severe in patients with recurrent sub occlusive episodes or inability to maintain a normal body weight.

Abstract
582 Background: Effectiveness of liver metastasectomies was evaluated in liver-MCRC patients treated with FIr-B/FOx association in a previous phase II study (Bruera et al, submitted 2010). Methods: Treatment schedule: 12h-timed-flat-infusion/5-Fluorouracil 900 mg/m2 days 1-2, 8-9, 15-16, 22-23; Irinotecan 160 mg/m2, Bevacizumab 5 mg/kg days 1, 15; Oxaliplatin 80 mg/m2 days 8, 22; every 4 weeks. Resection rate, activity, efficacy were analysed and compared in liver-only versus multiple metastatic sites and single versus multiple liver metastases. Results: Liver-MCRC were 33: liver-only 22 patients (67%); multiple metastatic sites 11 patients (33%). Liver metastasectomies were performed in 13 patients (11 R0, 84.6%): 26% of 50 MCRC patients enrolled in the FIr-B/FOx phase II study; 39% of liver-MCRC patients; 54% of liver-only, 6 of 9 (67%) single and 6 of 13 (46%) multiple liver metastases; one liver and lung metastasectomy. Pathologic complete responses (CRs) were 2 (15%); downsizing with modification of surgical resectability, 9 patients (41%); conversion rate of unresectable liver metastases, 83%. Overall activity, including 3 clinical CR, in liver-only patients, 68%. ORR, PFS, OS, respectively: in liver-MCRC patients, 84%, 11 and 23 months; in liver-only metastases, 86%, 17 and 44 months; in liver metastasectomies, 100%, 21 months (PFS from liver surgery 10 months) and 47 months. Significantly increased efficacy: PFS and OS in liver-only versus multiple metastatic sites (p 0.006 and 0.011, respectively) and single versus multiple liver metastasis (p 0.026 and 0.022, respectively). Conclusions: FIr-B/FOx chemotherapy increases resection rate of liver metastases, thus significantly improving efficacy of liver-only MCRC patients. No significant financial relationships to disclose.

Abstract
Pd allergic contact dermatitis is increasing in the general population; aim of this preliminary study was to determine, in women with Pd sensitization, the cytokine release from PBMC exposed to Pd nanoparticles similar to those emitted from catalytic converters. PBMC of 8 non-atopic and of 5 Pd sensitized women were incubated with LPS stimulation in presence of Pd nanoparticles (5-10 nm) or potassium hexa-chloropalladate 10(-5) and 10(-6) M. This Pd salt inhibited IFN-gamma, TNF-alpha, IL-10 and IL-17 release from PBMC of non-atopic women, whereas Pd nanoparticles enhanced the release of IFN-gamma and inhibited that of TNF-alpha and IL-17. In the Pd-sensitized women, with high basal values of cytokine release, the 10(-5) M Pd salt (but not Pd nanoparticles) inhibited IL-10 and IL-17 release. In conclusion, Pd salt inhibits the cytokine release from PBMC, whereas Pd nanoparticles exert modulatory effects enhancing release of IFN-gamma which plays an important role in autoimmune diseases.

Abstract
Chronic intestinal pseudo-obstruction is a severe, often unrecognized disease characterized by disabling and potentially life-threatening complications over time. The diagnosis is based on the evidence of typical clinical manifestations, radiological evidence of distended bowel loops with air-fluid levels, and the exclusion of any organic obstruction of the gut lumen. The radiological sign of intestinal occlusion allows the distinction from enteric dysmotility, which is characterized by better outcomes. Manometry can play a supportive role in defining the diagnosis, and differences in the manometric pattern of chronic intestinal pseudo-obstruction and enteric dysmotility have been shown. The disease is often unrecognized, and the diagnosis, therefore, delayed by several years. Thus, the majority of patients undergo useless and potentially dangerous surgeries. Long-term outcomes are generally poor despite surgical and medical therapies characterized by disabling and potentially life-threatening complications over time. A substantial percentage of patients requires parenteral nutrition. Failure of this nutritional support represents an indication for small bowel transplantation.

Abstract
Obesity is common in psoriatic patients, and it has been shown to be important for many aspects of the condition. In particular, low-calorie diets can improve the symptoms and response to treatment in pustular psoriasis. The present study investigates the influence of body-weight alteration on the disease's clinical manifestations in moderate to severe psoriasis patients treated with biological drugs. Finally, the influence of a caloric restriction was assessed. This observational transversal study enrolled 33 patients attending our Severe Psoriasis Outpatient Clinic, who were treated with biological drugs. Body Mass Index (BMI) was used as a diagnostic indicator of being overweight and of obesity. Waist circumference was also measured. Body weight and Psoriasis Area Severity Index (PASI) index were measured at follow-up visits at 4 and 8 months. Nonparametric test of Mann-Whitney was used to detect the differences between patient groups. Fisher's exact test was performed to evaluate the different results depending on the therapeutic changes of BMI. There was a strong prevalence of overweight-obese individuals in the group with a mean BMI of 30.59 +/- 6.94. Waist circumference was also above normal in the majority of the patients. Obese patients had a PASI index higher than the average of the whole group (25.03 +/- 12.43), with grade III obese patients having an average PASI of 44 +/- 3.37. At the first and second follow-ups, patients who put on weight did not achieve PASI 50; patients who had a stable weight presented variable response to treatment, while patients who decreased their weight achieved PASI 90 or PASI 75 even when not responding at the first. Further studies are needed to understand if the poor response observed in heavier patients is due to biological drugs pharmacokinetics or because therapy should be BMI based rather than administered in fixed doses, posing then an ethical consideration.

Abstract
The purpose of this study is to analyse the perception of occupational risk by building workers in an area of Central Italy. Three hundred male building workers compiled questionnaires including 7 different types of dangers: falling from height, cuts and wounds to body and eyes, manual handling of loads, noise, vibrations and dust inhalation. The workers quantified, on a scale of one to five, the potential injury and frequency of occurrence of each risk, as well as providing information on the possibility of checking/avoiding the risk. Furthermore, attendance of the workers at previous specific courses on accident prevention and the effectiveness of these was evaluated. A possible correlation between the perception of job risk and having had previous injuries was also assessed. The results showed that about 35% of workers do not consider their job hazardous; moreover, the risk perception is higher regarding dangers producing immediate injury, as opposed to those producing occupational illnesses. Moreover, there is no direct relationship between considering the job dangerous for health and having attended training courses, while the relationship between risk perception and past injuries is more marked. In conclusion, accident prevention training is essential for building workers; however, it is even more important to improve the quality of workers' information in order to increase their awareness of danger.

Abstract
The object of this study is to determine the cytokine release from PBMCs exposed to Pd model nanoparticles emitted from catalytic converters. PBMCs of 8 healthy non-atopic women were incubated in the presence of Pd nanoparticles (5-10 nm) or salt (potassium hexa-chloropalladate) 10-5 and 10-6 M. Release of cytokines in supernatant of PBMCs was then determined. In cultures without LPS, IL-10 and IL-17 release from PBMCs was inhibited by Pd salt, while Pd nanoparticles inhibited TNF-alpha and IL-17 release. In LPS-stimulated cultures, release of IFN-gamma, TNF-alpha, IL-10 and IL-17 was inhibited by Pd salt, whereas IFN-gamma release was enhanced and TNF-alpha and IL-17 release was inhibited by Pd nanoparticles. In conclusion, Pd salt inhibits cytokine release, whereas Pd nanoparticles exert modulatory effects enhancing the release of IFN-gamma, a Th1 cytokine typical of delayed allergic reactions. This result is interesting considering the increase of allergic contact dermatitis to Pd in people exposed to Pd nanoparticles in urban environments.

Abstract
Rat myocardial fiber development and formation is a complex event which begins in the early stages of fetal life and continues until the end of the first month of life. In fact, a progressive morphological structure arrangement is observed until the 22nd day of life. These modifications are based on biochemical events which are switched on at plasma membrane level and then transduced into the nucleus. Since the presence of Protein Kinase C (PKC) inside the nucleus could allow the enzyme to phosphorylate also proteins located on chromatin, on nuclear matrix and speckles, in this study attention was paid to the role played by phospho-Protein Kinase C-alpha (p-PKCalpha) in regulating the activation of SC-35 splicing factor which leads to the occurrence of morphological modifications during post-natal rat heart development. Besides the parallel increase of the expression of both proteins up to 4/8 days of life, firstly p-PKCalpha and SC-35 co-localize at nuclear level at day 1 after birth, thus suggesting a main role of p-PKCalpha in modulating the early transcription of components related to post-natal rat heart development.

Abstract
Objectives are to investigate the effects of benzo[a]pyrene (B[a]P) on the autonomic nervous system of coke oven workers. One hundred eighty-four coke oven workers were divided into 3 groups according to their working sites (coke oven bottom group, coke oven side group and coke oven top group), and 93 referents were recruited. B[a]P monitored by air sampling pumps as well as urinary 1-hydroxypyrene (1-OH-Py) was determined by high performance liquid chromatograph with a fluorescence detector (HPLC-FD). The autonomic nervous system (ANS) function was determined by 4 tests: Valsalva Manoeuvre heart rate variation (HR-V), variation of heart rate when breathing deeply (HR-DB), variation of heart rate when instantly standing up (HR-IS, including RR30:15 and RRmax:min) and variation of blood pressure when instantly standing up (BP-IS). The B[a]P mean concentrations in coke oven bottom, coke oven side and coke oven top were 19, 185 and 1,623 ng/m(3), respectively. The levels of urinary 1-OH-Py were markedly higher in the 3 exposed groups than that in the referent group (p<0.01). No significant difference was found in each group between smokers and non-smokers (p>0.05). Compared with referents, HR-V decreased significantly in coke oven workers (p<0.01), representing modulation of parasympathetic nervous function. However, no statistical differences were found in HR-DB, RR30:15, RRmax:min and BP-IS between the exposed groups and the control group (p>0.05). HR-V decreased with the increment of 1-OH-Py (p<0.05), and results of multiple linear stepwise regression demonstrated that external exposure level and duration of education entered the HR-V model; age was a significant factor of HR-DB and RRmax:min, but no variable was involved in RR30:15 and BP-IS regression. Benzo[a]pyrene affects the autonomic nervous function of coke oven workers mainly by down-regulating the parasympathetic nervous function.

Abstract
In 2006, in the context of the initiative aimed at "Promotion of safety and health of workers in construction yards", the Operative Unit of Occupational Health, University G. d'Annunzio, in collaboration with the Construction School of the Province of Pescara and INAIL, started a survey of construction yards around Pescara aimed at collecting data regarding respect of the specific law concerning construction yards and the risk perception of workers. The survey of 100 construction yards provided useful information towards a concise picture of safety levels obtained. In addition 300 interviews were carried out with workers to find out about their knowledge of accident prevention, how important they considered the use of personal protection devices, how often they used them, reasons for not using them, the devices most used,....and any injuries that occurred. The studied showed that, although the situation as improved compared to the past, further steps need to be taken.

Abstract
Accidents in building sites led us to study risk perception in workers employed in this field. We disposed of 300 workers, aged 18-65, who had to answer to a questionnaries were signing among seven risks the more present in their activity, chosing among five levels. So for each risk the worker had to quantify parameters such as: danger, frequence of accidents, actitude to risk-control, training on risk. The risk of falling from high sites has been perceived as extremely dangerous but it is possible to control it. Less dangerous is eyes exposition to chemical agents or dust. Manual movementation of weight and lacerations would be the most frequent source of accidents. Moreover would be insufficient the capacity to control the rick related to Weight manual movementation and vibrations. Workers answered in questionnaries that risk training on vibration was not sufficient, on the contrary they knew the risk of falling from high site. So we conclude that to reduce accidents in building sites it is necessary make better training on field, modifying the individual behavior among workers.

Abstract
Our unit of occupational medicine has been asked to solve the problem of an incrising percentage of workers affected by low-back pain in a clinic for patients with handicaps. The consequence of this affections caused frequently absences at work. We organized a course for training about correct methods for moving patient not self-sufficient. The 84 workers, all female (aged 30-45), had to sign on a card all the problems they found at work and their possible solutions according to them. Then we put the cards in a box and we red each one, signing on a blackboard the problems, using a red pen and the solutions proposed, in blue. Bed organization, turnation of patient, and the difficulties in the use of lifter were the principal problems, solved trought the training course made. Then we obtained a reduction in absence at work for low-back pain of about 40% after six months since the beginning of a course of posture exercises made in the same clinic one day a week after work.

Abstract
Here we present an overview of the experimental evidence and of the conceptual basis for the involvement of lamins and nuclear envelope proteins in a group of genetic diseases collectively referred to as laminopathies. Some of these diseases affect a specific tissue (skeletal and/or cardiac muscles, subcutaneous fat, peripheral nerves), while others affect a variety of tissues; this suggests that the pathogenic mechanism of laminopathies could reside in the alteration of basic mechanisms affecting gene expression. On the other hand, a common feature of cells from laminopathic patients is represented by nuclear shape alterations and heterochromatin rearrangements. The definition of the role of lamins in the fine regulation of heterochromatin organization may help understanding not only the pathogenic mechanism of laminopathies but also the molecular basis of cell differentiation and ageng.

Abstract
Seven women and eight men, exposed to low frequency (50 Hz) electromagnetic fields (EMFs) in a museum for 20 hours a week, were investigated in the years 1999 and 2005. During the first study, the mean EMF exposure in the working place was 1.7 microT and 1.1 microT, respectively. In the first investigation, the EMF-exposed men showed reduced blood NK lymphocytes in relation to controls, while EMF-exposed women presented reduced PHA-stimulated IFN-gamma release from peripheral blood mononuclear cells (PBMC). In the year 2005, blood cytotoxic activity, state and trait anxiety (STAI I and II, respectively) and occupational stress were also investigated. The scores of STAI I and II of the control women were slightly higher than those of the control men. EMF-exposed men showed higher occupational stress but normal immune parameters. EMF-exposed women showed, in relation to controls, lower PHA-stimulated IFN-gamma release from PBMC and reduced blood cytotoxic activity/CD45+-CD16+-56+ NK lymphocytes (but not per ml of blood). One of the women exposed to EMF, who worked a night shift, showed marked lymphopenia with very low NK lymphocytes and reduced IFN-gamma release; these immune parameters returned to normal following a change of work site. This study suggests that low frequency EMFs affect the immune functions of women more than those of men. Moreover, the determination of immune parameters seems to be a useful marker of the health effects of exposure to EMFs.
