Muscoloskeletal disorders and occupational stress of violinists.

Although musculoskeletal disorders are the most frequent cause of occupational diseases in musicians, very few studies have focused attention on a single category of instruments, in particular on the violin. This involves, in its practice, almost all the areas of the body, besides being in the category of strings which is the most numerous in an orchestra. A specific protocol, investigating postural and clinical profiles of the musculoskeletal apparatus as well as job stress, was utilized in a conservatory on graduates in the tenth year of violin study, who regularly participated in activities of orchestras or string quartets. The investigation revealed target segments of osteoarticular apparatus (jaw, vertebral spine, shoulders, elbows, hands and fingers, lower limbs) electively subjected to overuse, as well as muscle contracture of trapezoids and hyperkeratosis of fingers and clavicle. Although the work environment was comfortable, most violinists claimed to undergo intense rhythms and competitiveness. This study, highlighting subclinical occupational diseases in young musicians (violinists) suggests adequate prevention measures.

[Innovation in the ergonomic procedures for evaluating risk in building activities of the Abruzzo region (Italy)]. / Innovazione nelle procedure ergonomiche per la valutazione del rischio nel settore edile in Abruzzo.

After the earthquake of L'Aquila, INAIL further stimulated the local Universities to train specialists in the prevention of occupational risks on construction sites. Since 2005 the University of Chieti-Pescara evaluated occupational stress (through the Karasek's JCQ) as well as perception of occupational risk of the building workers. Moreover, procedures (including planning) in the field of building technology were analyzed. The perception of job strain of the workers in building activities were high because of elevated job demand and low decision latitude. The risk perception was higher regarding dangers producing immediate injury. There was no direct relationship between considering the job dangerous and having attended training courses, while the relationship between risk perception and past injury events was marked. At present, we are also evaluating, by instrumental methods, the biomechanical overload of workers, due to the main repetitive and forceful manual activities.

Occupational stress, job insecurity and perception of the health status in Italian teachers with stable or temporary employment.

The object of this study is to analyse job stress and insecurity and the perception of symptoms (health status) of 374 teachers (30 women and 74 men) with stable or temporary employment in schools in Pescara, a town in Central Italy. Job strain and job insecurity were analysed by an Italian version of the Karasek?s questionnaire, the perception of the health status by a 12 item test, and state and trait anxiety by STAI I and STAI II. There were no significant differences depending on the type of school. The young women with temporary contracts showed only higher levels of job insecurity than the women with stable employment, while those over 50 years old also showed more elevated values of job strain. Men with temporary contracts showed higher levels of both job insecurity and state and trait anxiety. The following highly significant correlations were observed: a) in women, job strain and perception of symptoms vs STAI I and STAI II (p<0.001); b) in men, job strain, job insecurity and perception of symptoms vs STAI II; job strain vs perception of symptoms as well as a negative correlation of decision latitude vs job insecurity, STAI I and STAI II (p<0.01). These results highlight differences in the perception of job insecurity between men and women. In particular, the decision latitude (skill decision + decision authority) plays an important role in men; temporary employment is mainly related to anxiety in men, while anxiety enhances the perception of poor health status mainly in women.

[Anxiety, job stress and job insecurity among teachers with indefinite or definite time contract]. / Ansia, stress lavorativo e "job insecurity" negli insegnanti a tempo indeterminato e determinato.

Object of this study was the occupational stress of 336 teachers (276 women and 60 men) with stable or temporary employment in schools of Pescara, town of Central Italy. The levels of anxiety were determined by STAI and STAI II, those of job strain", "job insecurity" and social support by the Karasek's questionnaire, and the perception of subjective symptoms by a 12 item test. There were no significant differences depending on the type of school. The women with temporary contract showed higher levels of "job insecurity", while the men with temporary job showed also higher values of STAI I and STAI II. The scores of anxiety of the women were positively correlated with "job strain", "job insecurity" and perception of subjective symptoms and negatively with social support, while the only correlations of STAI I and STAI II of men showing statistical significance of men was that with "job insecurity. Job strain was negatively correlated with the perception of symptoms both in women and men. These results evidence differences in the occupational stress of men and women; in particular, job insecurity may enhance anxiety in men.

[Risk perception in a group of dentists from Abruzzo]. / Percezione del rischio in un gruppo di odontoiatri Abruzzesi.

Dentist's office represents an area with high infectious risk both for workers and patients. With our study we tried to analyse the relationship between dentists and prevention. We studied 104 dentists who had to answer to a questionnaire composed by 25 questions on topics such as job management, risk perception, measures adopted for prevention and knowledge about normatives regarding safety at work. From the answers we can conclude that dentists know the risk present in their work and use correctly the individual preventive dispositives; make blood control to test hepatitis markers, in particular HCV. But only 68% made HBV vaccination. Many dentists,even if they know the way of transmission of HIV, avoid to cure positive patient.

[Occupational stress and job insecurity in men working in a university]. / Stress lavorativo e "job insecurity" in uomini che lavorano nell'università.

77 men working in a university were investigated. Trait and state anxiety were determined by STAI I and STAI II; job strain (job demand/decision latitude), social support and job insecurity were analysed by a 46 item Karasek's questionnaire and subjective symptoms by a 12 item test. The employees of a library (mean age 49 years), in contact with students, showed significantly higher values of job strain, STAI I, STAI II and subjective symptoms than a control group of employees with similar age. Young employees and sanitary staff with temporary employment showed higher level of job insecurity than control subjects with stable position. Blood cytotoxic activity (reported in another study) was significantly lower in the old employees with job strain or in the young employees with job insecurity (but not in the sanitary staff) than in the controls; this demonstrates that not only occupational stress but also job insecurity may play an important role in affecting the health status.
