Cobalt myocardiopathy. A critical review of literature.

Cobalt is regarded as being responsible for a form of myocardiopathy whose pathogenesis and clinical description must still find a specific place in the range of congestive myocardiopathies. In spite of this, epidemiological studies are not sufficient to prove the role of cobalt in inducing myocardiopathy in hard metal workers. This critical review intends to evaluate if hard metal exposure may induce toxic effects on the heart. In this context, the literature considered ranges from pioneer reports on 'beer drinkers' to the more recent papers concerning cases of patients occupationally exposed; subjects who, after a surgical operation died of fulminant heart failure and, lastly, hard metal workers who were examined for their cardiac function. Various pathogenetic mechanisms related to possible cardiac effects in hard metal workers have been analyzed. The most likely should be the inhibition of cellular respiration due to inhibition of the mitochondrial dehydrogenase.

Cardiac function study in hard metal workers.

The induction of cardiac effects in hard metal workers is uncertain. This study investigates cardiac function of a group of 31 hard metal workers with or without pulmonary disease. The average duration of exposure to cobalt containing dusts was 10.4 years (range 1-30), while the environmental levels of cobalt exposure ranged from 0.09 to 13.6 mg/m3 Co. Cardiac function has been studied by: ECG (electrocardiogram), exercise test (ET), ECG 24 h according to Holter (ECGH), echocardiogram (ECHO) and radionuclide angiocardiography with 99Tc (RNA). The aims of this work were (i) to show the existence of cobalt myocardiopathy in the workers analyzed and, (ii) to find an early indicator of cardiac dysfunction which could be used in the clinical examination of hard metal workers. Within the group of patients with hard metal lung disease, cases of myocardiopathy of doubtful aetiology have been found. The cardiac indexes obtained through RNA show ventricular dysfunction in healthy hard metal workers which could be a manifestation of initial pulmonary artery hypertension or of an early occult cor pulmonale due to an unknown fibrotic lung disease.

[Health surveillance in construction].

In the Italian and international literature there are very few studies about work diseases and their prevention in the construction's compartment. The analysis of the most recent articles about this theme, however, suggests the presence of an high professional risk in the compartment and indicates as the most relevant risk factors noise, dusts, fibres, manual lifting, prolonged fixed postures, cumulative trauma disorders, vibrations, chemical substances and climatic conditions. The role that extra-lavorative risk factors can play on health is also relevant; those risks are due to the workers' peculiar life-style: hyper caloric diet, smoke and use of alcohol. Interventions of medical hygienic prevention, formation and information are therefore necessary. Lombardy Region, which from many years is careful to the problems about the prevention in building yards, has created a Working party who has elaborated the "Guide Lines for the sanitary surveillance in the building industry". The indications reported in the Guide Lines could represent, even for the occupational-doctors of the building contractors of the New Hospital, a good base for the working out of the workers' health care activity, in the respect of the dues of the law in force.

[Occupational disease in construction work].

BACKGROUND: There are very few studies in the Italian and international literature concerning occupational diseases and their prevention in the building industry. OBJECTIVES: The aim of this study was risk assessment in the building industry. METHODS: We analyzed the international literature and the results of our cross-sectional study, which involved more than 1000 workers. RESULTS: The analysis of several studies and of our experience suggests a high occupational risk in this field and shows as main risk factors: noise, dusts, fibers, manual lifting, prolonged static positions, repetitive motions, hand-shoulder and whole-body vibrations, chemicals and weather conditions. In addition, non-occupational risk factors can influence health: e.g., habits and lifestyle, like hypercaloric diet, cigarette smoking and alcohol consumption. CONCLUSIONS: Preventive measures and training initiatives are urgently needed to improve the safety and the health among building workers.

[Cardiovascular assessment in building activities using an ergospirometer].

We report preliminary results of a current study aimed to evaluated peak oxygen consumption and others cardiopulmonary exercise test parameters, in some common and tiring building activities, with the use of a portable ergospirometer stress test (Metamax 3B, Cortex Biophysik). We tested 3 Building School's Teachers of Seriate (Bergamo): the materials handling and transport of cement bricks and to dig with pick and shovel reaches peak anaerobic threshold into few minutes while the activity of make molter permits an aerobic metabolism in all building workers tested.

[Prevalence of risk factors and prevention of coronary disease in a population of construction workers of the Province of Bergamo].

Authors describe the prevalence of cardiovascular risk factors among 1.348 construction workers, enrolled in a five years lasted health surveillance program. Our results confirm both the high prevalence of cardiovascular risk factors and the need of further examinations other the clinical, laboratory, electrocardiogram and chest X, in order to point out a correct diagnosis and evaluate the fitness to job. Furthermore, we underline the usefulness of training in health education for the prevention of cardiovascular disease, considering the low extent to which individuals perceive their own risk.
