[Work-related injuries in Monfalcone shipyard (2000-2010)]. / Il fenomeno infortunistico nei lavoratori della cantieristica navale del cantiere di Monfalcone (Gorizia) dal 2000 al 2010.

Shipbuilding industry exhibits higher injury rates at the workplace than those reported in other industrial sectors. Work-related injuries (n = 6714) occurred from 2000 to 2010 at the shipyard of Monfalcone (Gorizia-Italy) were considered. Injury frequency incidence (IF = number of accidents/number of workers x 1000) and injury severity rate were estimated. Among permanent (directly employed) shipyard workers, the IF ranged from 294.6 in 2000 to 113.7 in 2010. Injury severity rates showed the same decreasing trend. The IF for contract workers was unchanged over the calendar period (110.5 in 2000 to 110.9 in 2010) with no significant change in the injury severity rate. These findings suggest an improvement of the working condition for permanent shipyard workers as a result of prevention policies (education and surveillance) and the automation of production processes. Further preventative interventions are suggested to minimize work-related injuries and to promote health and safety in the shipbuilding industry.

[Active search of work related diseases: the example of carpal tunnel syndrome in Pordenone's area]. / La ricerca attiva delle malattie professionali: l'esempio della sindrome del tunnel carpale in provincia di Pordenone.

In the recent years working related pathologies of the upper limbs have raised at the top of ranking of diseases reported to INAIL in the Northern East Area of Italy. In 2004 658 cases of tendinitis have been filed and 361 cases of the Carpal Tunnel Syndrome (CTS) reported on a total of 1317 and 864 cases respectively in the whole Italian territory. The phenomenon (6.8% of total occupational disease in Pordenone province) interests essentially women and various working environments widely represented. We have worked together with an important Diagnose and Treatment Medical Centre to find new cases of professional illnesses, initially focusing our efforts on the CTS. We have identified 26 new cases of CTS as possibly originated from working conditions and we have filled 11 reports to the Judicial Authorities. In a training meeting with Orthopedic Doctors we have disclosed the results of our research while at the same time we have also divulged our knowledge on the importance of the working environment in the onset of the CTS providing the tools for a correct reporting of suspect cases.

[Allergic sensitization and latex-associated symptoms in a group of health workers]. / Sensibilizzazione allergica e sintomi associati al lattice in un gruppo di lavoratori della sanità.

The presence of symptoms connected with the use of latex rubber gloves and sensitization to this allergen was studied in a group of 660 hospital workers who regularly used gloves as a means of protection. Symptoms connected with the use of gloves were reported by 153 subjects (23.2%) and were significantly associated with female subjects length of use and type of medical care. The majority of cases reported irritative symptoms (13.2%) whereas contact dermatitis and rash were reported by 3.6% and 5.5% of cases respectively. Systemic reactions (asthma and/or rhinitis) were reported by 5 subjects. Prick tests for latex were positive in 23 cases (3.5%), 15 of which were symptomatic. Positive skin reaction to latex was significantly associated with family atopy, personal case history and prick test. It is concluded that the presence of symptoms and sensitization to latex requires the implementation of preventive measures in order to reduce the risk of sensitization to a minimum, in addition to removal from exposure of those subjects who are already symptomatic or at risk.

Sensitization to green coffee beans and work-related allergic symptoms in coffee workers.

BACKGROUND: Occupational respiratory allergy to green coffee beans (GCB) and to castor beans (CB) was studied in 112 workers in a modern coffee manufacturing plant of Trieste (Italy), where the process is completely automatic, the environmental conditions are good and where exposure to CB can be considered absent because since 1970, only new sacks have been used for coffee transportation. METHODS: All subjects were interviewed by a trained doctor using a questionnaire to investigate allergic symptoms and predisposing factors. Sensitization to GCB and to common allergens (pollens, molds, house dust mites) were evaluated by the skin-prick test. The serum of subjects with a positive skin-prick test to CGB or who had symptoms at work was tested for specific IgE (RAST) for GCB and CB. Lung function was evaluated by a Ponigraph spirometer. RESULTS: Sensitization to GCB was found in 25.8% of green coffee workers (31 cases), in 2.7% of roasted coffee workers (37 cases) and in 4.5% of the clerks (44 cases), p < 0.01. The evaluation of IgE specific for CB gave positive results only in 3 of 10 subjects sensitized to GCB. A total of 20% of GCB workers (6 cases) complained of work-related respiratory symptoms (asthma and/or rhinitis) compared with only one subject in the roasted coffee group and one in the control group (p < 0.01). Asthma was reported by 2/31 of the green coffee workers and by 1/44 of roasted coffee workers. CONCLUSIONS: There was a significant correlation between sensitization to GCB and work related symptoms (p < 0.01), common allergic symptoms (p < 0.05) and atopy by prick test (< 0.01). These results point to the need to evaluate atopic status in workers and identify the most susceptible subjects, with the aim of informing them of their at-risk status and monitoring their progress. This makes it possible to diagnose sooner those symptoms possibly indicative of a work-related disease, because even in presence of good environmental conditions and even when symptoms are mild, it is almost always the atopic subjects who are affected.

Latex symptoms and sensitisation in health care workers.

BACKGROUND: Natural rubber latex has become an important occupational health concern, particularly among health care workers, who for protection are required to wear latex gloves when at work. This study evaluated the prevalence of latex-related symptoms and sensitisation among a large group of health care workers in Trieste hospitals. METHODS: We evaluated the prevalence of latex-related symptoms in 1,165 health care workers, by means of a questionnaire, a medical examination, skin prick tests and IgE-specific evaluation. We determined atopy and latex sensitivity by skin prick tests using a battery of common inhalant allergens, a commercial latex extract (Lofarma Allergeni, Milan) and individual skin puncture tests for each of the vegetables immunologically related to latex (potato, tomato, chestnut, banana, kiwi fruit). Associations between potential risk factors for latex allergy were assessed. RESULTS: Glove-related symptoms were noticed on 17.2% of the nurses (200) the majority of symptoms being mild dermatitis with itching and erythema (120 subjects, 11.1%). Symptoms suggestive of IgE-mediated latex allergy were found in 51 subjects: 35 (3%) complained of contact urticaria and 16 (2.2%) complained of asthma and/or rhinitis. The resulting symptoms were significantly related to skin prick tests that were positive to latex (odds ratio (OR) = 11.89; 6.40-22.2), to personal atopy (OR = 2.15; 1.47-3.12), to familiar atopy (OR = 2.12; 1.48-3.03), to skin prick test positivity to related fruit (OR = 2.01; 1.16-3.46) but not to prick test positivity to common inhalant allergens (OR = 1.00; 0.71-1.39). Symptoms increased as a direct function of the time-usage of latex gloves and were more prevalent in operating room staff. CONCLUSION: In this large cross-sectional study, glove-related symptoms and latex skin sensitisation appear to be substantial among health care workers, and are related to common signs of atopy. We stress the need of preventive measures to avoid latex exposure when health care workers are at risk of developing allergy symptoms.
