Work-related stress is an emerging risk for psychiatric occupational disorders including Adjustment Disorders (AD). The aim of this study was to investigate in workers exposed to occupational stress suffering from AD about putative indices of stress and mental health resilience such as serum cortisol (seC) levels, Heart Rate Variability (HRV) and affective temperaments. We consecutively recruited 15 male and 15 female AD patients between workers evaluated for occupational stress at an Italian Occupational Medicine Unit. SeC levels were measured by specific immunoassay. HRV indices were recorded using Task Force® Monitor system (CNSystems, Graz, Austria). Specific questionnaires were used to measure perceived and occupational stress, psychopathological symptoms and temperament. Women presented higher levels of occupational stress, higher High-Frequency HRV (HF-HRV) and lower Low-Frequency HRV (LF-HRV) than men. SeC levels were positively correlated with LF-HRV values and negatively with HF-HRV values. The LF/HF ratio resulted to be inversely correlated with the score of Harm Avoidance temperament dimension and directly with the score of Reward Dependence temperament dimension. In conclusion, in AD patients exposed to occupational stress high seC levels and reward dependence appear to be associated with a pattern of HRV reflecting less mental health resilience.

Introduction: Adjustment Disorders (AD) which develop in response to work-related stressors represent a model of psychiatric occupational disease. Major Depressive Episodes (MDE) although often associated to work-related stressors are unlikely recognized by insurance institutes as occupational diseases. Affective temperament and mood spectrum symptoms are possible factors of vulnerability to stress. The aim of this study was to investigate if temperaments and mood spectrum symptoms had a different distribution among workers exposed to occupational stress and suffering from different psychiatric disorders (AD, MDE)., Methods: 156 AD and 97 MDE patients were recruited and evaluated with scales for perceived stress (PSM) and work-related stress (JCQ), for psychopathological symptoms (BDI-II, SAS), for affective temperament (TEMPS-A[P]) and for lifetime mood spectrum symptoms (MOODS-SR). Group comparisons and correlation analyses between variables were performed by parametric or non-parametric statistical tests according to variables distribution., Results: The diagnostic groups did not differ for perceived and occupational stress levels. MDE patients reported significantly higher BDI-II score and MOODS-SR scores than AD ones. The hyperthymic temperament was significantly more frequent in AD than in MDE group. The hyperthymic score, differently from other dimensions of temperament and from mood spectrum components, negatively correlated or did not correlate with psychopathological symptoms severity and perceived stress levels., Limitations: Predictive limitation because of cross-sectional design., Conclusions: The hyperthymic temperament as opposed to lifetime subtreshold mood symptoms appears to be more represented in patients suffering from occupational AD than in MDE ones. Acknowledging vulnerability factors to job stress could support clinicians in occupational diseases prevention and management., (Copyright © 2022 Elsevier B.V. All rights reserved.)

Objectives: A literature review was performed to highlight which work-related diseases express sex/gender differences in health outcomes and focus the main limits of studies in this field., Methods: The research, carried out on PubMed by specific search string, identified 4828 articles (1997-2017 period) of which 381 are eligible for review (4-22%, depending on the disease)., Results: Among them, 68% reported sex/gender differences in health outcomes, which in most cases appear to be due to different exposure and/or work segregation rather than to biological differences. However, few studies place this assessment among the research goals and results are almost never discussed and hypothesis are seldom formulated about any observed differences., Conclusions: It seems necessary to use research methodologies and study design that can detect and explain the described complexity and useful in defining appropriate preventive strategies., Competing Interests: The authors of this article have no conflict of interests to disclose., (Copyright© by Aracne Editrice, Roma, Italy.)

Scientific literature suggests a relationship between military occupation and the development of brain tumors, but no italian study has investigated on the impact of this job on the brain cancer morbidity. In this a study information were obtained from patients recruited in the Neurosurgical Department of the University-Hospital of Pisa, Italy, from 1990 to 1999. The study has been conducted as a case-control study. 161, newly diagnosed cases of brain tumors (glioma and meningiomas, histologically confirmed), were recruited, such as 483 controls (with other non tumoral neurologic diseases: trauma, hemorrhagic brain disorders, aneurism, etc), by matching cases and controls (1:3), for age (± 5 years) and gender. Cases and controls were interviewed in the Neurosurgical Department, University-Hospital of Pisa, Italy, and the occupational histories of cases and controls were compared. Cases and controls have showed a statistically significant difference, based on their occupation (military vs. non-military occupation). A statistically significant association was seen between brain tumors and military occupation among evaluated patients (p=0.013). Further studies regarding this population group are needed, to determine the causes for the increased risk of this cancer. Furthermore, a subsequent reevaluation in other patients collected in more recent years will be needed to evaluate the trend of this association.

Objectives: A thorough and fully application of the principles of gender mainstreaming, in accordance with the European Community guidelines, to the health and safety at work, implies the systematic review of the whole prevention from the gendered point of view. This means that both biology- and gender-based differences between male and female workers should be conceived not only as determinants of health but also as factors affecting either positively or negatively the health and safety risk prevention. In this evolutionary cultural step the role of the occupational physician is particularly important., Methods: In this paper we propose some operative tools that can concretely implement gender perspective in all the various areas of prevention, where the occupational physician has a leading, if not even exclusive, role such as risk assessment, training and health medical surveillance., Competing Interests: The authors of this article have no conflict of interests to disclose., (Copyright© by Aracne Editrice, Roma, Italy.)

Even though a relationship between farmer work and the development of brain tumors was suggest by the scientific literature, a small number of italian studies investigate on the impact of this job on the cancer morbidity of farmer population. The informations about this case-control study were obtained from patients recruited in the Neurosurgical Department of the University-Hospital of Pisa, Italy, from 1990 to 2000. One hundred and seventy-four, newly diagnosed cases of brain tumors (glioma and meningiomas, histologically confirmed), were recruited, such as 522 controls (with other non tumoral neurologic diseases: trauma, etc), by matching cases and controls (1:3), for age (± 5 years) and gender. Cases and controls were interviewed in the Neurosurgical Department, University-Hospital of Pisa, Italy, and the occupational histories of cases and controls were compared. Cases and controls have showed a statistically significant difference, based on their occupation (agricultural vs. non-agricultural). We observed a significant association among brain tumors and rural activity in evaluated patients (P=0.008). Further studies regarding this population group are needed, to determine the causes for the increased risk of this cancer, particularly in regions where there is an intense agricultural activity and where pesticides are used. Furthermore, a subsequent reevaluation in other patients collected in more recent years will be needed to evaluate the trend of this association.

We report our experience about the medical surveillance of 739 workers previously exposed to asbestos. They were observed during the period between January 2009 and May 2012. The diagnosis of 594 patients, that were observed for the first time, were analyzed in order to assess the presence of benign or malignant pulmonary diseases that is so found: 16.33% of benign pulmonary diseases related to asbestos, 17.84% benign pulmonary diseases not related to asbestos and 1% of malignant pulmonary diseases probably related to asbestos. The diagnosis of 221 patients, that were followed over time, were analyzed in order to assess the evolution in time: a new onset of pulmonary disease was found in the 2.26%, a worsening of the pulmonary disease was found in the 6.79%.

The GGT enzyme, considered for years only as a marker of liver disease and alcohol abuse, has now revealed a risk of death for many causes. Through a molecular exclusion chromatography on FPLC system (Fast Protein Liquid Chromatography), it is possible to discriminate four fractions of GGT, defined according to the molecular weight: big-GGT, medium-GGT, small-GGT and free-GGT. The objective was to study the preventing meaning of GGT fractions for asbestos-related diseases. This study was conducted on 129 workers previously exposed to asbestos, 22 patients affected by Malignant Pleural Mesothelioma and 107 healthy workers. Our data demonstrated a statistical significant correlation between the fraction free-GGT with the presence of MPM, suggesting a possible role for this molecule as a biomarker for MPM diagnosis. However, being a preliminary study, further studies are warranted to confirm our results.

The study analyzes the prevalence of thyroid disease in 1960 healthcare workers, classified as occupationally exposed to ionizing radiation, who have worked at the University Hospital of Pisa. They underwent a medical surveillance protocol from January 2005 until Mars 2012 at the Operative Unit of Occupational Medicine. A positive history of thyroid disease was found in 221 persons, but only 110 (the 5.61% of the population) developed the disease during or after the occupational exposure. Benign thyroid diseases, found in 93 workers, were in order of frequency: Hashimoto's thyroiditis, nodular disease, Basedow's disease, multinodular goiter, subacute thyroiditis and hypothyroidism. Malignant thyroid diseases were found in 17 workers (the 0.87% of the total population), 15 workers suffered from the papillary histotype and 2 from the medullary histotype.

Background and Aims: Increased concentrations of soluble mesothelin-related peptides (SMRP) have been found in sera of patients with malignant pleural mesothelioma (MPM) even if a relatively high rate of false positives has hampered their clinical use as a tumor marker. Individual SMRP levels could be affected by polymorphic elements. The aim of this study was to investigate the association between single nucleotide polymorphisms within the promoter-5'UTR regions and SMRP levels in healthy asbestos-exposed individuals and patients suffering from MPM.?, Methods: The promoter-5'UTR regions of the mesothelin gene were genotyped in 59 healthy asbestos-exposed subjects and 27 MPM patients. SMRP levels were measured using a commercially available ELISA kit.?, Results: Two novel polymorphisms, an A>C variant (called New1) and a C>T variant (called New2), were identified. In healthy subjects, high SMRP levels were associated with the C-variant of New1, with an average 1.62-fold increase compared with AA homozygotes (p<0.0001). Most of the C-allele carriers had SMRP levels above the threshold of 1.00 nM. We set two different SMRP cutoffs on the basis of the combined New1+New2 genotypes.?, Conclusions: New1-New2 genotypes could be employed as markers for setting individualized and appropriate thresholds of "normality" when SMRP is used in surveillance programs of asbestos-exposed people.

The percentage of bladder cancer as occupational disease in West-Europe is of 5/10%, but only a few amount of them are recognized as occupational disease from INAIL. The above mentioned research project is realized in order to decrease the gap between expected and claimed cases of occupational disease and it is conducted with the collaboration of ASL of Pisa, ASL of Empoli, Azienda Ospedaliera Universitaria Pisana and INAIL. 677 patients with bladder cancer were interviewed by phone, among them 64 subjects had a working experience compatible with neoplastic risks because had a previous occupational exposure to aromatic amines and metal working fluids. These cases were discussed into a Medical Staff and 40 cases were considered "probable" for occupational disease, 18 "possible", 3 cases are suspended for more research, 3 cases are considered "no professional disease". The research allows finding out a great number of bladder cancer, increasing the total amount of workers with occupational disease. The integrated approach with the collaboration among different institutions is surely the best way to allow and guarantee a suitable and right protection of workers with occupational disease.

Recently, Tuscany regional government has promulgated (Regional law n. 464/07) guidelines for setting up suitable sanitary rooms for patients allergic to latex. These guidelines enforced the managers of the Tuscany Local Health Units to promote educational activities and a correct methodology for the safe management of both health workers and patients who need latex-free diagnostical and/or therapeutical procedures. An other Regional law (n.345/05) had previously enforced all the Tuscany Local Health Units managers to implement and update a Registry of every latex-allergic patients ever hospitalized in their own local facilities. Since 2002 a multi-disciplinary task force of health operators, lead by the Preventive Medicine Section, has been elaborating and implementing a plan for the safety of latex-allergic patients of the Pisa University Hospital, along with a Registry where each of these patients were recorded. Moreover, since 2005 under the responsabilities of the staff of the Preventive Medicine Section, another Registry has been implemented and updated. In this Registry all the Hospital employees who have been diagnosed a latex allergy, through the medical exams performed within the occupational medical surveillance activity, have been filed. In this study we report the results of this preventive activity both aimed at patients and heatlh operators safety.

Background: The rising awareness of psychological harassment at the workplace means that it is ever more important to collect clinical data and test tools to assess psychiatric disease connected with this phenomenon., Objectives: The aim of the study was to assess the experience gained by the centre for work maladjustment of the University Hospital of Pisa on a sample of patients, using the methods proposed by the centre at the Clinica del Lavoro "Luigi Devoto"., Materials and Methods: The patients were submitted to a diagnostic protocol consisting of work history, medical examination, psychological assessment, psychiatric examination, subjective questionnaires, mood scale and Neutest. The analysis was made in two phases in which 109 subjects were examined to check occupational stress effects in the period March 2002 - July 2004, after which 50 subjects were selected (45.9%) with the adaptation disorder and a history of adverse working conditions., Results: The data gathered showed a slight predominance of workers from the public administration sector. The most representative range of duration of the psychological violence varied from 6 months to 2 years (46%). From close examination of the causes of the maladjustment disorders, structural changes in organization appeared to be the most frequent (13 cases). Among patients with positive diagnosis of disorder caused by psychological violence at the workplace, three situations were prominent: attitude to being a social outcast, behaviour to ignore proposals, and professional declassing., Conclusions: The multidisciplinary approach was culturally very stimulating and fundamental in reaching a final diagnosis of occupational disease: diagnosis of bullying at work and related disease was possible only thanks to the fact that three specialists agreed on the aetiological role of psychological harassment at the workplace. Our experience confirms that psychological harassment can cause health impairment and the most common diagnosis is maladjustment disorder.
