Relation between somatic development and some environmental factors in the male population of vocational mining schools in the Lublin Coal Basin.

Somatic development of a child, although genetically determined, depends also on the influence of biogeographic and socio-economic factors of the environment. The effects of these factors popular in the literature are seen in the differences of somatic development of children brought up in urban and rural environments. In comparison with urban population, country children are characterized by lower growth and body mass, delayed manifestation of sexual maturity, greater amount of incorrect posture features, worse state of nutrition and lower index of mental development. The differences in somatic development of children were also found while comparing the size of agglomeration and socio-professional factors determining parents' level of education and financial situation of the family. One could also observe the improvement of somatic development of children living in regions of quick and intensive urbanization and industrialization.

Evaluation of lung function in male population from vocational mining schools of the Lublin Coal Basin.

Occupational exposure to dust and other environmental factors in coal miners may impair the lung function of workers. Besides the coal workers' pneumoconiosis, the inhaled dust may cause decreased ventilatory capacity as a due to chronic bronchitis (9, 13). The same diseases, especially chronic bronchitis, are common in general population and may arise not only from occupational reasons (11, 12). The involvement of the genetic factors, environmental pollutions and cigarette smoking should be considered.

[Risk factors of coronary artery disease in males during a 3 year follow up based on a cohort study in a selected region of Lublin].

To assess changes in risk factors of coronary artery disease, examinations which had been performed in 1981 and 1982 were repeated in males aged 40-59, inhabitants of the district "Czechów" in Lublin. The study was based on Polish Experiment of Coronary Disease Multifactor Prevention assumptions 112 of 203 males investigated in 1981, 1982 underwent repeated examination (attendance rate - 55%). Statistical analysis was performed only in twice examined subjects. Significant increase of blood pressure, body weight, total serum cholesterol and uric acid concentration was stated in comparison with their respective initial values. Significant decrease of HDL-cholesterol and no changes in serum triglycerides concentration were observed. The only positive stated alteration was a lower percentage of tobacco smokers. Diagnosis of coronary artery disease remained unchanged despite of increased risk factors levels (increase of mean Rose's index score from 5 in initial examination to 6.5 in a control one). This high increase in risk factors occurrence allows an unfavourable prognosis for future incidence of coronary artery disease and also demands to undertake vigorous prevention.

Lead poisoning among household members exposed to lead-acid battery repair shops in Kingston, Jamaica.

To investigate the risk of lead poisoning among household members exposed to 'backyard' battery repair shops (BBRS) in Kingston, Jamaica, environmental and blood lead (PbB) were measured at 24 households (112 individuals) with a BBRS worker or located at a BBRS premises and at 18 neighbourhood control households (74 individuals). Elevated PbB (greater than or equal to 25 micrograms per decilitre [micrograms/dl]) was common among subjects of all ages living at BBRS premises, especially among children less than age 12, 43% of whom had PbB greater than 70 micrograms/dl. Potentially hazardous soil and house dust lead levels were also common at BBRS premises, where 84% of yards had soil lead levels above 500 parts per million (geometric mean 3388 parts per million [ppm] at BBRS premises households with a BBRS worker). Geometric mean blood and environmental lead levels were significantly lower at control households, where less than 10% of subjects in all age groups had elevated PbB (maximum 33 micrograms/dl). Sharing a premises with a BBRS was a stronger determinant of household blood lead and environmental contamination than was the presence of a BBRS worker in a household. Blood lead levels were associated with soil and house dust lead levels in all age groups. We conclude that small battery repair shops, which have also been described in other developing countries, create a high lead poisoning risk for nearby residents.

[Prevalence of coronary disease risk factors in the male population 40-59 years of age from the housing complex "Czechów" in Lublin].

There was studied randomly selected approximately 10% sample of population of males aged 40-59 from the housing estate "Czechów" in Lublin. Authors assessed the level of coronary artery disease (CAD) basic risk factors as well as a percentage of persons with a high risk of developing CAD. The study was extended by determinations of plasma HDL--cholesterol, glucose and uric acid concentrations. Mean total cholesterol concentration (220.4 mg/dl) as well as the frequency of hipercholesterolemia occurrence (15.4%) were significantly higher in comparison with their values in male populations of Warsaw and Southern Poland. Mean systolic (134.2 mm Hg) and diastolic (87 mm Hg) blood pressures as well as frequency of hypertension occurrence (22.7%) were comparable with results of two, above mentioned, epidemiological studies. We stated the lower percentage of current tobacco smokers (52.2%). The overweight of 115% or more was stated in 22.2% of persons. Very high percentage of men of low physical activity was stated (51%). Higher level of respective risk factors reflected in individual score of CAD risk coefficient fixed on 5 points and being higher than in other studies of different Poland regions populations.

[Content of overall fat in the body and levels of selected coronary risk factors].

Authors estimated total adipose mass based on skinfold measurements in 205 males aged 40-59, residents of the housing estate "Czechów" in Lublin. They studied the correlations among calculated total adipose mass and arterial blood pressure as well as serum lipids levels. It was stated, that total adipose mass of the examined group was similar with those of other urban males populations. Total adipose mass well correlated with arterial blood pressure and serum triglycerides levels, but poorly with total serum cholesterol concentrations. Greatly significant inverse correlation between total body adipose mass and a concentration as well as a percentage of HDL-cholesterol was proved.

Debilitating cutaneous poxvirus lesions on two captive houbara bustards (Chlamydotis undulata).

Poxvirus was isolated from cutaneous nodules on two young Houbara bustards (Chlamydotis undulata) bred in captivity in Saudi Arabia. Birds were emaciated and presented nodules on tibiotarso-tarsometatarsal joints, toes, and the carpal joint. Diagnosis was confirmed by histopathology, virus isolation on inoculated chorioallantoic membranes of embryonated chicken's eggs, and electron microscopy. Progressive leg lesions were extensive and interfered with walking, significantly debilitating the birds. Successful excisions of these lesions were performed.

Cross-protection test of an avian poxvirus isolated from houbara bustards.

An avian poxvirus was isolated previously from the houbara bustard (Chlamydotis undulata). We carried out a cross-protection test on 66 captive-bred canaries. Thirty-five canaries were vaccinated with a commercial canary poxvirus (CP) vaccine. Three weeks later all 66 birds were assigned randomly to six different groups: group Ia (n = 14) was vaccinated and challenged with houbara bustard poxvirus (HP) strain; group Ib (n = 13) was vaccinated and challenged with a CP strain; group Ic (n = 7) was vaccinated and not inoculated; group IIa (n = 14) was nonvaccinated and challenged with HP strain; group IIb (n = 11) was nonvaccinated and challenged with a CP strain; and group IIc (n = 7) was not vaccinated and not challenged. Vaccinated groups (Ia, Ib, Ic) had no losses and remained healthy. All of the birds (100%) in group IIb died within 10 days, and 10 birds (71.4%) of group IIa died within 20 days. The nonvaccinated control group (IIc) remained healthy. Poxvirus was isolated from the liver, digestive tract, lungs, and inoculation lesions of nonvaccinated dead CP- and HP-challenged birds. Secondary bacterial infections were higher among nonvaccinated HP-challenged birds (85.7%) than in nonvaccinated CP-challenged birds (25%). The results of this experiment reveal a degree of immunogenic relatedness between CP and HP strain and support the recommendation that houbara bustards be vaccinated with a CP vaccine.

Infective endocarditis--changes in the microbiological profile.

The clinical material from 120 patients, with clinical diagnosis of infectious endocarditis (IE) (65 patients with IE on native valves and 55 patients with IE on artificial valves, i.e. mechanical or biological prosthesis) treated during the period of 1986-1994 was investigated. Sixty positive cultures were obtained from the valves and 40 positive cultures from the blood, which accounted for 76% and 60% of the confirmed IE cases, respectively. Bacteriological confirmation of IE was obtained in 91 (75.8%) patients, 80.2% of the isolated microorganisms being gram-positive bacteria, 17.6% gram-negative, and 2.2%-fungi. The most frequently isolated bacteriawere coagulase-negative staphylococci. They accounted for 40.5% of infections in the IE patients on native valves, and for 63.3% in those with artificial valves. Streptococci were isolated from 11.8% of the patients with IE on native valves and from only 2% of cases of IE on artificial valves. The multiresistant strains were most frequently isolated from the patients with IE on artificial valves.
