Abstract: The working ability evaluation is a process of numerous examinations, measurements and estimates that are done by a team of medical and other experts. It is utterly unacceptable to think that the opinion about someone's working ability is given by some individual specialist of any expert domain especially regarding the invalids' category since this can lead to either confusion or undesired conflicts between the patient and those who are professionally and legally qualified to evaluate his working ability. In order to carry out the medical part of the expertise for evaluating the working ability it is necessary have an accurate diagnosis of particular disease, an opinion whether the process is definite or can be improved by and adequate therapy in addition to the state of morphology and function of all the organs and systems essential for responding to the biological requirements of the working operations at a given job as well as the estimate of the functional ability of the organs or systems. The practical evaluation of the working ability also has to include the professional utilization factor, that is, it is necessary to determine the working operations' requirements as well as the conditions in which they are performed at a given job. Within the working ability it is necessary to take into consideration the psychosocial structure of the sick person, years of age, qualification and professional degree as well as the society's possibility to accept the proposals made by the medical and other experts. Tn judging the working ability of the patients having a cardiac disease it is indispensable to view every case separately since it always implies its own factors. The evaluation must be done in specially-qualified institutions having an adequate team of experts including a specialist of labor medicine, a cardiologist, a safety-at-work expert, a technologist, a psychologist, a social worker and other medical and non-medical staff.

Abstract: The rheumatic diseases are present to a high percentage in the working - active population. There is a great number of professional causes of the diseases as well as specific job's requirements that can unfavorably affect the emergence and the evolution of the rheumatic diseases. The evaluation of the working ability is a procedure that correlates and brings into accord the job's requirements with the morphological- functional state of the engaged systems and of the organs of the exposed worker. This is a very delicate and responsible task aiming at placing the worker at such a job that most corresponds to his psycho-physical characteristics, that is, at a job at which he will best carry out his assigned duties without violating his health. The proper attitude in evaluating the working ability of the rheumatic patients is an important step to be taken in order to prevent the rheumatic disease complications. The removal of the sick worker from the job at which there are some potential professional disease causes as well as the requirements that unfavorably affect the bone-joint, muscular and vascular system of the exposed worker represents an important therapeutic and preventive measure since it can slow down the disease's evolution and thus ease the workers' troubles. The recognition of the professional disease, of the bodily damage and of the right to the care and aid represents an important assistance to the sick worker thus helping him to exert his right concerning the medical, social and disabled protection.

Abstract: While speaking about nutrition and food, most people start from a widely acceptedassumption that there is nothing unknown about the topic, that is, thateveryone naturally knows what is needed for nutrition. The truth is, however, just theopposite.The knowledge about a specific state in which an organism subjected to somephysical strain finds itself, especially when dealing with workers and sportsmen, hasled to the development of a science dealing with the nutrition needs of the mentionedprofessionals. Today the science has available data stating that the proper nutritionregime increases the endurance for about 40% while, at the same time, the workintensity rises for about 25%. The changes can be also perceived in the convalescenceperiod duration after injuries; with proper nutrition it also gets considerably shorter.A decreased rate of injury, as well as a longer working life, are the sufficient reason forpaying more attention, in the future, to the study as well as proper use of food.

Abstract: Introduction: Blood pressure, heart rate and lipoprotein lipids are affected by family history, obesity, diet, smoking and physical activity habits. The aim of this paper was to estimate the values of blood pressure and heart rate in professional handball and water polo players before and after training and submaximal exercise test and to analyze the lipid state in these professional athletes in comparison with people who have never been in sports. Material and methods The investigation included 30 professional handball players, 30 professional water polo players and 15 men who have never been in sports (control group). All groups were matched for age, smoking habits, family predisposition to arterial hypertension and dyslipidemia. Results Between these groups there were statistically significant differences of blood pressure values and heart rate in the state of rest, after exercise test and after the training. There were also statistically significant differences of total cholesterol values, LDL cholesterol, triglycerides, HDL cholesterol, LDL cholesterol/HDL cholesterol ratio and total cholesterol/HDL ratio between these groups. Discussion Differences between these groups can be explained by various values of body mass index, by activity of lipoprotein lipase in athletes, by body position during the sports activity, by thermoregulatory vasoconstriction in the water, and by effects of hydrostatic pressure and reflex mechanisms during swimming. Conclusions Cardiovascular reaction in professional athletes depends on the type of sports activity, body position and medium during training. Professional athletes have a lower atherogenic risk than non-sportsmen. Changes of blood pressure and heart rate after submaximal exercise test are not the same as changes after training. .

Medicinski Pregled , 2004, DOI: 10.2298/mpns0412536j
Abstract: Introduction Occupational injuries are the leading cause of morbidity and mortality among workers. The aim of this study was to analyze the frequency of occupational injuries and health status of workers. Material and methods The examined group consisted of 3.750 workers with health disorders. The control group included 1.800 healthy workers. Both groups were similar in terms of many factors that could contribute to the occurrence of occupational injuries. The injury rates were calculated in both groups. Results Workers with psychomotor and sensorimotor disorders, neuroses, obstructive sleep apnea, arterial hypertension, diabetes mellitus, hearing, vascular and sight impairments have been frequently injured compared to workers with other diseases. Discussion Due to the belief that accidents and occupational injuries are preventable, it is an imperative to study those factors which are likely to contribute to occurrence of accidents. The contributing factors could be the physical and mental state of workers. Conclusion Occupational injuries are significantly more common in the examined group than in controls.

Medicinski Pregled , 2004, DOI: 10.2298/mpns0402022j
Abstract: Introduction Organic solvents are chemically different compounds with one common feature: they dissolve fats, oils, resins, cellulose acetate and cellulose nitrate, which makes them widely used in industry. Most often organic solvents are used in paint and lacquer industries, in production of pesticides, plastics, explosives, rubber, cellulose, air conditioners, in pharmaceutical industry and in leather industry. The aim of this research was to analyze the working environment and professional hazards in paint and lacquer manufacturing industry and evaluate effects of chronic exposure to mixture of organic solvents on nervous system of exposed workers. Methodology The exposed group consisted of 50 workers professionally exposed to these noxae, while the control group consisted of 30 workers who have never been exposed to these noxae. Results Examination of working environment in departments of paint and lacquer manufacturing revealed presence of white spirit and toluene above allowed levels. Exposed workers more frequently complained of fatigue, hand numbness, enhanced excitation, and concentration difficulties, forgetfulness and headaches, than workers from the control group. Electroneurographic examination of n. medianus showed reduced motor and sensitive conduction velocity among exposed in comparison to workers from the control group. Reduced motor and sensitive conduction velocity was correlated with duration of exposure to these noxae. Terminal latency of n. medianus was statistically, significantly longer in the exposed group than in the control group. Workers in the exposed group have statistically significantly longer reaction time in response to acoustic and visual stimuli. Discussion Segmental demyelination and axonal degeneration, as forms of damage to peripheral nerves, were identified as responsible for peripheral neuropathy associated with occupational exposure to organic solvents. Conclusion Results of this study show possible neurotoxic effects of noxae detected in the phase of analysis of working conditions and working environment of examined workers.

Abstract: Introduction Arterial hypertension is an important medical, social and economic problem in the working population. Factors of occupational exposure lead to a much faster and more frequent occurrence of this disease and its consequential complications. Among these factors the following take an important place: noise, carbon monoxide, job dissatisfaction, microclimate conditions, chemical agents, shift work, night work, monotonous work and so on. The purpose of this study was to analyze working conditions, working environment, work demands and identification of occupational Stressors and their influence on development of arterial hypertension. Material and methods This investigation included 3470 workers and it examined technological processes, working time, job satisfaction, interpersonal relations and physical and chemical hazards of their workplaces. The exposed group consisted of 2270 workers occupationally exposed to Stressors. Control group included 1200 workers whose workplaces were without Stressors. Workers of exposed group were divided into 14 subgroups in regard to presence of occupational hazards. Results Arterial hypertension was established in 39.9% of workers of exposed group, which is statistically significantly more than in controls (25.7%). The highest prevalence of arterial hypertension was at workers who were dissatisfied with the job and who were at the same time occupationally exposed to noise and carbon monoxide. Family predisposition and smoking have cumulative effects with occupational hazards. Discussion Possible mechanisms of arterial hypertension development include activation of adrenergic nervous system, renin-angiotensin aldosteron system, higher concentrations of steroids, catecholamines and free radicals caused by occupational hazards. Conclusion Occupational Stressors are significant factors in development of arterial hypertension of exposed workers. The most important Stressors are noise, carbon monoxide and job dissatisfaction.

Abstract: Occupational asthma may be defined as asthma induced by acquired hypersensitivity to an agent inhaled at work. A lot of agents in the workplace have been shown to cause asthma and the list is growing as new materials and processes are introduced. There are two major types of occupational asthma. Sensitizer-induced asthma is characterized by specific responsiveness to the etiologic agent. The mechanism of irritant-induced asthma is unknown, but there is no clinical evidence of sensitization. Two other mechanisms by which variable airway obstruction due to workplace exposure can occur are reflex and pharmacological bronchoconstriction. Occupational asthma can be a challenging diagnosis to make and to prove. Tests which are used and are helpful include nonspecific pulmonary function tests, specific or bronchoprovocative pulmonary function test, serial pulmonary function tests (most commonly using the peak flow meter), and immunologic tests. Each test has its own drawbacks and none is perfect. Early diagnosis of occupational asthma and early removal of patients from exposure are important.

Abstract: The aim of this study is to examine the epidemiolog ical characteristics of traumatic occupa tional injuries in rubber industry workers registered in the period between the 1993 and 2003. The occupational accidental work-place in juries are most frequent among young, less experienced workers. The injuries in occupational acci dents are most fre quent in May, on Mon day, between 8 am and 10 am. The most common type of occupational injuries were closed fractures, open fractures and dislocated fractures. Upper and lower extremities were the most frequently injured parts of the body in occupational injuries. These injuries resulted in 70.4 ± 5.8 days per injured worker, which is higher than in the literature data. These findingsare important for the control and prevention of occupational injuries in rubber industry.

Abstract: The aim of this paper is the analysis of electroneurographic and neurological findings at workers in chemical industry. An analysis of the working conditions in the cartridge and drying sections of paint and lacquer industry has shown an above permitted level of white spirit and toluene. The exposed group comprised 55 workers occupationally exposed to these noxae, whilst the control group included 35 workers who had never been exposed to the same agents. The exposed workers more frequently complained of numbness of the arm and leg, cramps in the shoulder and knee, and weakness in the arm and leg than did the control workers. The electromyoneurographic examination of the radial nerve showed that a decrease in motor and sensitive conduction velocity was more significant in the exposed group compared to the control. The reduction in motor and sensitive conduction velocity was in correlation with the length of exposure to the noxae. Terminal latency of the radial nerve was significantly longer in the exposed group compared to the control, with an increase proportional to the exposure length. The exposed workers had a significantly longer time of response to acoustic and visual stimuli. The results of the study suggest neurotoxic effects of the noxae detected in the cartridge and drying sections of paint and lacquer industry.
