RESUMO

System of training for occupational health and safety experts and occupational physicians has been analyzed in comparison with one of the most reliable occupational health and safety indicators--occupational diseases level and its changes during 1981-2010. Increased number of occupational diseases has been registered since 1996, reaching maximum in 2009 with 138.6 cases of occupational diseases per 100 000 employees.

RESUMO

AIMS: To establish if there is further evidence for the long-term oxidant stress injury (as reported previously--Kumerova et al. in Biol Trace Elem Res 77:1-12, 2000) in surviving Chernobyl nuclear power plant (NPP) workers from Latvia. The overall objectives of this study have been to establish if there have been long-term systemic changes in the oxidant/antioxidant status of clean-up workers that might reflect adaptation to the progression of oxidative stress injury. METHODS: Biochemical analyses of the circulating levels of endogenous oxidants and anti-oxidants were undertaken over two periods (Stage 1 in 1998-1999 and Stage 2 in 2005-2006) at approximately 6-7 years time interval, in order to establish if there have been time-dependent changes in the parameters that may be important for the health of the clean-up workers. The biochemical analyses included (a) plasma levels of the anti-oxidant, selenium, (b) blood and plasma levels of glutathione peroxidase, (c) red blood cell catalase, (d) plasma total oxidant status as lipid peroxides and hydroperoxides, (e) plasma ceruloplasmin, and (f) total blood levels of zinc and copper. RESULTS: The circulating content of lipid peroxides, plasma oxidisability, lipid peroxides, catalase, Zn, and Cu were elevated above normal values at both the stages of this study. Glutathione peroxidase was increased above normal values at Stage 1 but not at Stage 2. The most pronounced changes between Stage 1 and Stage 2 were (a) a reduction by about (1/2) in the content of lipid peroxides and lipid peroxidation, but not in the blood oxidisability and (b) increased plasma selenium. The data show that there may be a partial improvement in the anti-oxidant/oxidant status of the Chernobyl NPP workers over the 7-year period of investigation. CONCLUSIONS: The NPP patients may be undergoing progressive reduction in blood oxidants accompanied by adaptation to oxidant stress injury due to the increased anti-oxidant activity measured in their plasma and blood.

RESUMO

The authors demonstrated changes in occupational morbidity in Latvia over 1996-2007--that characterizes general state of the work safety system functioning. Analysis of occupational morbidity structure and occupational accidents rate proved trends of changes in those parameters. Considerably higher occupational morbidity was seen since 1996 to 2004. Afterwards slight decrease in the morbidity was demonstrated, but since 2007 the occupational morbidity increased again. Occupational incidence per 100,000 workers was 20.4 in 1996, 184.5 in 2004, 139.3 in 2007. Occupational accidents rate per 100,000 workers reached 163 in 1996 and 194 in 2007.

RESUMO

The health status of some 6,000 workers from Latvia who went to clean-up the Chernobyl Nuclear Power Plant (CNPP) site following the explosion on 26 April 1986 has been analyzed. The data on these workers have been recorded in the Latvian State Register of Occupational disease patients and people exposed to ionizing radiation due to Chernobyl NPP accident (Latvian State Register) that was established in 1994. From these data, estimates have been made of external ionizing radiation to which these workers were exposed together with observations on the impact of exposure to heavy metals (especially lead and zinc) and radioactive isotopes released during the reactor 'meltdown'. These factors along with psycho-emotional and social-economic stresses account for a marked excess of mortality and morbidity in the group of CNPP accident clean-up workers compared with that of the non-exposed normal Latvian population adjusted for age and sex. The number of diseases or conditions in the CNPP accident clean-up workers has progressively risen from an average of 1.3 in 1986 to 10.9 in 2007. This exceeds for the Latvian population when adjusted for age and sex. The most serious conditions affect the nervous, digestive, respiratory, cardiovascular, endocrine (especially thyroid) and immunological systems. While the morbidity associated with diseases of the respiratory and digestive systems has decreased in recent years that in the other systems is increasing. In recent years, there has been an increased occurrence of cancers affecting the thyroid, prostate and stomach. Clinical and laboratory investigations suggest that surviving CNPP accident clean-up workers exhibit signs of immuno-inflammatory reactions causing premature aging with evidence of autoimmune diseases and immunological deficiencies or abnormalities. It is suggested that the CNPP accident clean-up workers may have a specific syndrome, the 'Chernobyl post-radiation neurosomatic polypathy', due to sustained oxidant stress injury, as a result of exposure to radiation and lead.

RESUMO

The authors demonstrated appropriateness of some subjective methods evaluating strain in workers engaged into road building and determined work hardiness categories, considering peculiarities of individual methods. Calculations using empiric equations covered energy consumption during workers' dynamic activities. Empiric equations were proved to point to higher energy consumption, if compared to results of experimental methods. Objective evaluation of work hardiness involved heart rhythm monitoring through a device transforming heart rate into metabolic energy, kcal/min.

RESUMO

New system of occupational medicine in Latvia is under development already for 10 years. The biggest efforts have been invested in creation of legal basis harmonized to the legislation of EU and extensive training of specialists. The State Labour Inspectorate was established, the Institute of Occupational and Environmental Health and other medical institutions have been reorganised. A new system of information is under construction; as well as new hygienic standards are being elaborated.

RESUMO

BACKGROUND AND OBJECTIVES: Traditionally the neuromuscular disorder associated with lead poisoning has been purely motor. This study assessed peripheral nerve function clinically and electrophysiologically in 46 patients with neuropathic features out of a total population of 151 workers with raised blood and/or urinary lead concentrations. RESULTS: Average duration of occupational exposure for the neuropathic group ranged from 8-47 years (mean 21.7). Their mean blood lead concentration (SD) was 63.9 (18.3) microg/dl (normal <40), urinary lead 8.6 (3.3) microg/dl (normal<5.0), urinary coproporphyrins 66.7 (38.4) microg/g creatinine (20-80), urinary aminolaevulinic acid 1.54 (0.39) mg/g creatinine (0.5-2.5). All 46 had distal paraesthesiae, pain, impaired pin prick sensation, diminished or absent ankle jerks, and autonomic vasomotor or sudomotor disturbances. Reduced vibration sensation and postural hypotension were present in all 20 studied. None of these 46 patients had motor abnormalities. Motor conduction velocity and compound muscle action potential amplitudes were normal, with marginally prolonged distal motor latencies. Sensory nerve action potential amplitudes lay at the lower end of the normal range, and the distal sensory latencies were prolonged. No direct correlation was found between the biochemical variables, and the clinical or electrophysiological data. CONCLUSIONS: One additional patient was seen with shorter term exposure to lead fumes with subacute development of colicky abdominal pain, severe limb weakness, and only minor sensory symptoms. Unlike the patients chronically exposed to lead, he had massively raised porphyrins (aminolaevulinic acid 21 mg/g creatinine, coproporphyrins 2102 microg/g creatinine). Patients with unusually long term inorganic lead exposure showed mild sensory and autonomic neuropathic features rather than the motor neuropathy classically attributed to lead toxicity. It is proposed that the traditional motor syndrome associated with subacute lead poisoning is more likely to be a form of lead induced porphyria rather than a direct neurotoxic effect of lead.

RESUMO

The authors have reflected new trends in occupational health in Latvia. At present the whole system of general health care in Latvia is under consolidation and reconstruction. Thus, the occupational health and safety system of Latvia, as a nature part of general health care system is also under changes and reconstruction. Today Latvia's workforce consist of 1.68 million people, working in a large number of workplaces, mainly in industry and agriculture. There are still very hazardous working conditions in many workplaces. The total number of diagnosed occupational diseases ranges from 90 to 220 cases per year. If counted per 100,000 workers the rates of occupational diseases are 5.1 in 1981 and 23.4 in 1995. New system of occupational health is under development in Latvia. New legislation and regulations are published and extensive training for specialists provided. A new system of information is under construction as well as new hygienic standards. Main stress is paid to ensure that standards of EC are met.

RESUMO

Epidemiologic studies on the health effects of the Chernobyl disaster have focused largely on physical health, whereas the psychological consequences have received little attention. The authors have assessed the associations of various exposure variables with mental and psychosomatic distress in a sample of 1412 Latvian liquidators drawn from the State Latvian Chernobyl Clean-up Workers Registry. The outcome was a mixed mental-psychosomatic disorder occurring during 1986 to 1995. Comparisons among subgroups of the cohort classified according to exposure type or level were based on the proportional hazards model. Length of work (> or = 28 days) in a 10-km radius from the reactor (relative risk [RR] = 1.39, 95% confidence interval [CI] 1.14-1.70), work (> 1 time) on the damaged reactor roof (RR = 1.46, 95% CI 1.02-2.09), forest work (RR = 1.41, 95% CI 1.19-1.68), fresh fruit consumption (> or = 1 time/day) (RR = 1.72, 95% CI 1.12-2.65) are risk factors for mixed mental-psychosomatic disorder. Construction of the sarcophagus (RR = 1.82, 95% CI 0.89-3.72) is also associated with this outcome, although nonsignificantly. Distinguishing stress-related from radiation-induced effects in this data set was difficult and these findings should provide a basis for later hypothesis testing in other cohorts.

RESUMO

The major hazardous factors of the labour conditions in modern poultry farms are presented by dust mixtures including both vegetable and organic substances, biologically active substances and microorganisms, gaseous products, as well as unfavourable microclimate conditions and physical overload. Detailed medical examinations of poultry farmers revealed dependence of respiratory and pulmonary diseases, cardiovascular and nervous disorders on the labour conditions, the major etiologic factor being such allergens as feathers, down, blood serum, poultry excrements, bacteria and fungi.

RESUMO

In consequence of the analysis of workers' health status and microbic contamination of the working zone of animal and poultry husbandry production area the study established direct dependence of microorganism sensitization rate, incidence of infectious and allergic skin and respiratory diseases on microbic aerosol concentration. Feasibility of aerogenic microflora standardization was substantiated proceeding from the comparison of hygienic and clinical findings; MAC for microbic aerosol was set up for the working zone.

RESUMO

It was established that allergic diseases of poultry farmers were characterized by the shifts in immunoregulation expressed in terms of the decrease of the number of T-lymphocyte-suppressors, precursors of effectory and immunoregulatory T-lymphocytes, reduction of functional actifity of T- and B-cells along with an increase in the content of B-lymphocytes with antibody-dependent killers' sensitization and suppression of nonspecific protective factors. The results suggested that the use of immunomodulatory drugs helped to improve clinicoimmunologic indicators.
