Abstract
The CC16 microprotein is the main secretory product of Clara cells, which are epithelial cells lining lung airways. In crossing through the bronchoalveolar/blood barrier, CC16 diffuses passively into plasma. Serum CC16 (sCC16) has recently been proposed as a biomarker for detecting Clara cell impairments. The aim of this study was to assess if sCC16 concentrations are reduced in a group of healthy young smokers. A group of 118 healthy young males volunteered to take part in the study. Each subject answered a questionnaire, and provided blood and urine samples. Serum CC16, urinary cotinine and creatinine were measured. Median serum CC16 concentrations were lower in smokers than in non-smokers (11.3 mug l(-1) vs 14.6 mug l(-1); p = 0.005; N = 89 and 29, respectively) but did not correlate with either the daily or the life-time cigarette consumption, or with urinary cotinine concentrations. sCC16 did not correlate with age or body mass index in the whole study population or in the groups of smokers and non-smokers. These results suggest the reduction in sCC16 concentrations in a group of healthy young smokers may be an early effect of cigarette smoking.

Abstract
The road and rail transport sector, since the several work tipology and risk factors for workers safety and health, is an area where assessing exposure effects is very difficult. Muscoskeletal cardiovascular and neoplastic diseases are the disorders more frequently associated to professional drivers. The role of professional driving is rather well-defined in low back pain occurence, correlated to whole body vibration exposure. Professional drivers are at higher risk of ischemic cardiovascular diseases, but it is not clear whether the risk is attributable just to the occupational exposures or also to their life-style risk factors. Evidence of an excess of risk for lung, genito-urinary and hemolymphopoietic cancer is clear in the scientific literature for professional drivers. Anyway the lack in the control of confounding factors, in exposure assessment force to be very cautious in results interpretation.

Abstract
In many industrialized countries smokers have been observed in high prevalence among workers with poor educational status, who are usually exposed to major occupational risks. The smoking habit and passive smoking may by themselves, or through interactions with other occupational risk factors, cause the onset of serious diseases. Therefore health reasons and the legal obligation to observe the smoking ban in the workplace make it essential to prevent and combat smoking in the workplace and to promote smoking cessation in workers who smoke. This initiative should benefit not only workers' health and well-being but also company finances. The Occupational Physician should engage in diverse activities ranging from encouraging young people not to start smoking to providing programmes to encourage workers who smoke to abandon the habit. For example, he or she should i) inform managers, supervisors and workers about the high risks linked to smoking, passive smoking and obligations established by law ii) collect information about the smoking habit among workers and supply workers with the so-called minimal clinical intervention during routine health surveillance appointments and iii) collaborate with specific health promotion programmes in the workplace.

Abstract
This study assessed the smoking habit in 7,159 apprentices (females: 53.3%) in central Italy. In the period 1996-2006, each apprentice underwent a compulsory health examination to assess fitness for work carried out by specialists in Occupational Medicine. Demographic data and information on schooling, smoking habit, alcohol and coffee intake were collected by a questionnaire. Overall, 51.9% of apprentices were smokers. Smokers were fewer among female apprentices than among the males (48.3% vs 55.9%; chi-square test, p < 0.001). No decrease in the prevalence of smokers was evident during the study period. Low educational level, and daily intake of alcohol and coffee significantly increased the risk of being a smoker. Finding a high percentage of smokers among Italian apprentices with a low educational level who are employed in jobs for which few qualifications are required indicates the need for work-place activities against tobacco smoking habit. Specialists in Occupational Medicine who perform regular health surveillance of workers could play a role in the anti-smoking campaign by integrating their routine work with brief counselling sessions aimed at preventing smoking in young workers and helping smokers to stop and by collaborating in work-place health promotion programmes.

Abstract
INTRODUCTION Naphthalene, the most volatile polycyclic aromatic hydrocarbon (PAH), was recently classified as possible human carcinogen by International Agencies for Research on Cancer Humans may be exposed to naphthalene from a wide variety of sources, including occupation, environment, personal habits. We assessed urinary excretion of 1-naphthol (1-NAF), biomarker of naphthalene exposure, in non-occupationally exposed subjects. MATERIALS AND METHODS Urinary 1-NAF, 1-hydroxypyrene (1-OHP), biomarker of exposure to pyrene and cotinine, biomarker of smoking habits, were measured in 104 adults (53 men, 51 women). RESULTS 1-NAF concentrations overlapped in males and females (median: men 0.35 Microg/g creat; women: 0.46 microg/g creat). Median concentration of 1-NAF was 6-fold higher in smokers compared to nonsmokers (respectively, 7.7 microg/g creatinine vs 1.3 microg/g creatinine). Between smokers, urinary cotinine was positively correlated to 1-naphthol (rho: 0.69; p < 0.01) and 1-OHP (rho: 0.53; p < 0.01). Higher 1-OHP concentrations were found in smokers (median: smokers 0.16 microg/g creatinine, not-smokers 0.05 microg/g creatinine;). CONCLUSIONS In our study population, we found that 1-NAF excretion is much higher as compared to 1-OHP excretion. This is due to the ubiquitous presence of naphthalene in the environment. Smoking considerably increase the exposure to naftalene.

Abstract
The small dimension and particle shape of silica in gypsum used to prepare moulds for lost wax casting might be responsible for the high prevalence of silicosis in gold jewellery. To test this hypothesis, human pulmonary epithelial cell (BEAS-2B) cultures were exposed to two samples of silica with different crystal micro-morphologies: Silica Powder (Silica P) which is used in casting gold jewellery, and no powder Silica (Silica F). Extracellular matrix (ECM) production was evaluated using radio-labelled precursors and quantified by RT-PCR analysis. Expression of basic fibroblast growth factor (FGF2) and its receptor (FGFR2) was also evaluated. The results demonstrated Silica P particles had a very fine lamellar crystalline structure while Silica F was characterized by larger rounded crystals. Silica P stimulated collagen production significantly more than Silica F and downregulated laminin and metalloprotease expression. Both silica samples down-regulated FGF2 but only Silica F enhanced FGF2 receptor expression. In conclusion each Silica sample promoted a profibrotic lung microenvironment in a different manner and also elicited different FGF2 signalling pathways. The data confirm that different micromorphology of Silica particles affects the fibrogenic potential and the molecular mechanisms of dust pathogenicity.

Abstract
Upper extremity work-related musculoskeletal disorders, (UE-WMSDs) are one of the major causes of work-related disability in industrialized countries. Diagnostic criteria for many UE-WMSDs are still under debate, and several different national and international studies have attempted to reach a consensus agreement on the minimum criteria for case definition of UE-WMSDs. This paper describes clinical and diagnostic features of UE-WMSDs, focussing on carpal tunnel syndrome and rotary cuff tendinopathy.

Abstract
BACKGROUND Complementary or alternative medicine has become widespread in Western Countries and since the remedies are "natural" they are believed to be free of toxic effects and health risks. Ethnic remedies may contain lead, other metals and toxic substances. OBJECTIVES To show how lead poisoning as a result of using ethnic remedies may be severe enough to cause serious damage to health, and to increase awareness among family doctors and occupational physicians of the risks associated with ethnic remedies. METHODS AND RESULTS Description of ethnic remedy-related lead poisoning in 2 native Italian adults, with clinical, laboratory and toxicological data. CONCLUSIONS When metal poisoning is diagnosed, ethnic remedies should be included among the putative sources so as to avoid erroneous attribution to workplace exposure and application of unneeded preventive measures.

Abstract
Inorganic Lead can cause a toxic effect on Central Nervous System, Peripheral Nervous System and Autonomic Nervous System (ANS). A damage of the ANS can determine an heart rate variability (HRV) reduction. In this study 43 battery workers exposed to inorganic lead with mean PbB = 31.63 microg/dl (DS 14.77 microg/dl) and 35 not exposed subjects underwent to an evaluation of heart rate variability by specific tests. Heart rate variability in the exposed group was, for some tests (lying to standing, lying to standing-standing to lying) reduced compared with not exposed subjects and for other tests (Valsalva manouvre, lying to standing-standing to lying) correlated with PbB and Zinc Protoporphyrin (ZPP), but not with BMI, age and smoking habits. This study, like others conducted on similar populations, suggest an effect of occupational inorganic lead exposure on Autonomic Nervous System and heart rate variability

Abstract
In industrialised countries, carpal tunnel syndrome (CTS) is considered an epidemic work-related disease. We have set up the MODS (Malattie Occupazionali Da Sovraccarico biomeccanico, biomechanical overload-related occupational diseases) collaborative group, formed by epidemiologists, ergonomists and occupational physicians to investigate CTS in Italy, applying the methods that epidemiologists commonly use to understand epidemics. Several studies are already ongoing. Two different descriptive studies based on current hospitalisation data are in the reporting phase. A pilot case-control multicentre study (260 cases and 520 controls in 13 centres) is in the final phase of data collection. A longitudinal study on a cohort of 3000 subjects exposed to different risk factors has reached the third year of follow-up. Moreover, a surveillance system has been set up to cover selected districts of the Emilia Romagna region. These studies will generate new information about the prevalence and incidence of CTS in Italy, along with identification of regional, high-risk job titles and work sectors, and the relative influence of non-occupational factors.

Abstract
Using the International Project on Genetic Susceptibility to Environmental Carcinogens (GSEC) database containing information on over 15,000 control (noncancer) subjects, the allele and genotype frequencies for many of the more commonly studied metabolic genes (CYP1A1, CYP2E1, CYP2D6, GSTM1, GSTT1, NAT2, GSTP, and EPHX) in the human population were determined. Major and significant differences in these frequencies were observed between Caucasians (n = 12,525), Asians (n = 2,136), and Africans and African Americans (n = 996), and some, but much less, heterogeneity was observed within Caucasian populations from different countries. No differences in allele frequencies were seen by age, sex, or type of controls (hospital patients versus population controls). No examples of linkage disequilibrium between the different loci were detected based on comparison of observed and expected frequencies for combinations of specific alleles.

Abstract
Over the past decades advances in sciences and medicine have improved living and health conditions and lengthened life expectancy. These benefits are associated with an increase in prevalence of chronic degenerative diseases. With their multi-factorial aetiology these diseases are influenced by life styles and personal habits and require prolonged medical care and high social costs. Now days health is no longer considered as the absence of disease but a state of mental, physical and social well-being. The World Health Organization has defined health promotion as "the process of enabling people to increase control over and to improve health". Since the 70s in the USA many health promotion programmes have been proposed, especially by large corporations, in order to ensure a more efficient, productive and motivated work-force, to reduce health insurance costs and to provide a better company image. Workplaces,--particularly when the working population is relatively stable--are excellent areas for health promotion programmes because workers can be monitored over a long period of time. The most successful programmes are aimed at modifying behaviour in risk patterns (smoking, alcohol abuse, eating disorders, etc.) through information, active participation, screening, follow-up, personalized programmes, changes in the working environment, physical exercise programmes. These health promotion programmes are extremely hard to develop for Italian workers. Most firms are small or very small and much still remains to be done to eliminate well-known occupational risk factors. The current flexibility of modern work patterns could constitute a further obstacle.

Abstract
This report assessed lead absorption in community samples of the general population in Umbria, central Italy, in 1982 and in 1992. Each participant (128 subjects in 1982 and 479 in 1992) answered a questionnaire providing details of personal information and life style. Blood lead levels were determined by atomic absorption spectrophotometry. In 1992 hematocrit and glutamyltranspeptidase (gamma-GT) levels were also measured. In 1982 the mean blood lead level was 226 micrograms/l in males and 167 micrograms/l in females, and in 1992 it was still higher in males than in females (98 micrograms/l vs 61 micrograms/l) as were hematocrit and gamma-GT levels. Multiple regression analysis showed sex and age were the main factors accounting for 42% of the total variation in blood lead levels. They were followed by alcohol consumption, gamma-GT levels and smoking in this order. In conclusion, blood lead levels decreased significantly in central Italy in the decade 1982-92 and persistent lead absorption seems to be due to individual characteristics such as male sex, advanced age and a personal life style which includes alcohol consumption and smoking.

Abstract
These guidelines mainly deal with prevention of carcinogenic effects following occupational exposure to polycyclic aromatic hydrocarbons (PAH). After some toxicological remarks, the guidelines define a possible method to demonstrate and evaluate occupational exposure to PAH. In particular, it is illustrated the strategy of environmental monitoring and indicated which PAH should be measured, with suggestion about the most appropriate analytical techniques. As regards biological monitoring, the 1-OH-pyreneseems to be currently the most useful indicator since it reflects the recent and global exposure to PAH. The guidelines also give elements to interpret monitoring data, taking into account environmental and biological reference and limit values suggested by some authors, Associations, or current regulations. The most important health effects are carcinogenic and excess risks have been described mainly for lung, bladder and skin cancer in some PAH exposed workers. The studies on cytogenetic effects showed contradictory results. On the basis of such information and current regulations, the guidelines show how to perform health surveillance in preventive and periodical examinations and how to proceed for the information and formation of exposed workers. It is not advisable, on the basis of the current scientific data, to screen asymptomatic PAH exposed workers for early diagnosis of lung or bladder cancer, nor it is opportune the use of tumor markers for health surveillance nor is genetic screening applicable for individual susceptibility evaluation outside research programs.

Abstract
The evaluation of exposure to polycyclic aromatic hydrocarbons (PAH) should firstly comply with current regulations (D.Lgs. 626/94), that is, identify the compounds and exposed subjects, quantify exposure, adopt preventive measures and health and epidemiological surveillance. Environmental monitoring should take into account the technological cycle and the tasks with higher PAH exposure risk, and the main sources of emissions. In the case of skin contamination, it should be considered the measure of skin PAH by means of sampling or removal techniques; moreover, the determination of urinary hydroxypyrene (1-HP) should be performed. It is mandatory to analyse (Benz[a]) anthracene; Benzo[b]fluroanthene; Benzo[j]fluoranthene; Benzo[k]fluoranthene; Benzo[a]pyrene; Dibenzo[a,h]anthracene, i.e. the PAH marked with the R45-R49 phrase. When 1-HP determination is planned, Pyrene should be added. Biological monitoring has been addressed mainly to hydroxylated metabolites of pyrene and among these 1-HP, the main metabolite of pyrene, although non occupational factors, such as tobacco smoking and consumption of smoked foods are potentially confounding. Urinary mutagenicity tests which are heavily influenced by non occupational factors such as tobacco smoking and diet are not advisable. The determination of DNA and protein adducts is a promising test for evaluation of metabolic active dose but at the moment it is not suitable for routine use in occupational medicine. In order to interpret environmental and biological data, it will be useful to consider appropriate reference values ("limit" "guide", "operative", "maximum admissible") such as 0.1 mg/m3 for total PAH extracted with benzene, 5 micrograms/m3 for the mixture of 15 PAH listed by US NTP, the limits varying from 0.1 to 5 micrograms/m3 for Benzo[a]pyrene, and 2.7-4.4 micrograms/g creat, for 1-HP.

Abstract
This study, which was conducted in central Italy, included (a) 525 office workers employed in an air-conditioned building that had fan coil units in every room (building B) and (b) 281 subjects who worked in three naturally ventilated buildings (building A) that were operated by the same public administration. The prevalence of work-related symptoms was assessed by a questionnaire that was administered by an occupational medicine specialist. The most frequent complaints of employees in building B were dry air, strong lighting, and high temperature. Employees who worked in this building experienced a statistically higher prevalence of symptoms that were characteristic of the sick building syndrome. This is the first time that this syndrome has been reported in Italy. Excessive illumination, a low relative humidity, and fiberglass on floors and furniture might have contributed to the symptoms. Inadequate maintenance of the building's air-conditioning plant and the employees' lack of information regarding self-regulation of the fan coil units may also have contributed to the prevalence of symptoms.
