Analysis of the morbidity with temporary incapacity for work among workers at the ship building and ship repairing company

Aim: To analyse the yearly morbidity with temporary in capacity among workers at the ship building and ship-repairing company as compared to norm groups after Batkis-Lekarev, previously defined values according to groups of disease - standard and registered illnesses of the population aged 18 and above in general hospitals in Varna district for the period 2004-2006. The comparative analysis for the period 2004-2006 shows that the negative tendencies in the morbidity with temporary in capacity for work have decreased during the past year. The structure of morbidity shows that the basic reasons for temporary in capacity for work of the working team as a whole are mainly diseases of the respiratory, musculo-skeletal system and diseases of the peripheral nervous system, which can be explained with the specific type of work. Special attention should be paid to the fact that the frequency of absences from work be cause of malignant growths grows double each following year. The progression of the sickness related to the peripheral nervous system, neuroses and eye diseases is similar. The presence of some of these diseases could be related directly with the working conditions.Scripta Scientifica Medica 2009; 41(2): 191-194

Influence of air pollution in an urban area on hospital admissions from acute myocardial infarction

It has been established that the episodes of huge atmospheric pollutions like the London fog of 1952 are responsible for an increased mortality, the larger part of which from cardiovascular events. Aim of the study is to investigate the relation between the levels of atmospheric pollutants and the frequency of hospital admissions from acute myocardial infarction (AMI) in the city of Varna. Five hundred and eighty five patients were investigated from those who were admitted to the Intensive Care Clinic of St Marina University Hospital in Varna with a diagnosis of acute myocardial infarction (AMI) in the period from December 2004 to December 2005. For the same period from October 2004 to December 2005 the relationship between the quality of the atmospheric air and the frequency of hospital admissions form AMI was investigated. For the investigated period from 1 October 2004 to 31 December 2005 a total of 585 persons were admitted for treatment at the ICC with a diagnosis of AMI, of which 393 (67.2%) were men and 192 (32.8%) were women. The mean age for them was 64.05 ± 0.49 years (from 18 to 93 years of age). The frequency of hospital admissions from AMI show sta tis ti cally sig nif i cant correlational sub or di na tions with al most all stud ied at mo spheric pol lut ants. The atmospheric pollution in urbanised inhabited areas should be taken as a risk factor for cardio-vascular diseases. Monitoring of the quality of atmospheric air provokes multidisciplinary prophylactic interest, including the needs of cardiologic prevention. Scripta Scientifica Medica 2009; 41(2): 135-139

Influence of air pollution in an urban area on hospital admissions from acute myocardial infarction. Atmospheric pollution with ozone and particulate matter in the city of Varna

The combined action of the atmospheric pollutants as well as their combination with the meteorological parameters leads to alteration of their effects on the heart. Only for the ozone influence is described a relative independence from the rest of the toxic substances in combined action. Aim is to study the possibility for isolated and combined with the other atmospheric pollutants and conditions of work influence of the levels of particulate matter on the frequency of hospital admissions from acute myocardial infarction (AMI). Data obtained from the medical documentation on laboratory and instrumental investigations were assessed of the 585 patients admitted to the Intensive Care Clinic of University Hospital in Varna with a diagnosis of acute myocardial infarction (AMI) in the period from December 2004 to December 2005. Data from the Regional Inspectorate of Environment and Water and the Regional Inspectorate of Protection and Control of Public Health were analyzed for the mean daily values of the concentrations of ozone, general particulate matter and fine particulate matter (PM) in atmospheric air. The seasonal subordinations described as well as the variability of the effect in combined models of interaction give reason to assume reciprocal influence of the effects on the coronary blood flow of ozone in its combined influence with the other atmospheric pollutants, as well as in its combination with the various meteorological parameters, and from there indirectly with the sun activity. At the same time those effects are determined also by the diverse individual susceptibility of the exposed persons.Scripta Scientifica Medica 2010;42(2):125-12
