We have surveyed a population size of 6633315 from Diseases Surveillance Points (DSP) system in Gansu province for the last eleven years. The annual birth rate was 18.20% with an annual standard mortality rate 545.80/10(5). The annual standard mortality for male and female were 607.53/10(5) and 483.29/10(5) respectively. The major causes of death were Respiratory system diseases, Cardiovascular diseases, Neoplasms, Injuries, Digestive system diseases, Pediatric diseases, Infectious diseases in sequence. In eleven years, there seemed to be a rising trend in the mortalities of following diseases as: Cerebrovascular diseases, Ischemic heart diseases, Rheumatic fever and heart disease, Lung Cancer, Liver Cancer, Cancer of the Esophagus, Intestinal cancer, Cervical cancer, Injury, Congenital abnomalities, to different degrees. However, an obvious descending trend on the morbidity and mortality of infectious diseases was moticed. The average life expectancy was 71.05 years in DSP, with male 69.57 years, and female 72.72 years. Diseases with higher PYLL were Injuries, Neoplasms, Respiratory system diseases and the like. Data suggested not only the prevention andcontrol of infectious diseases, but also the surveillance of injuries and the prevention and control of chronic diseases should be strengthened.

One hundred male U.A.E. nationals (50 smokers and 50 non-smokers) rated their own risk for developing heart disease, developing arthritis and having an automobile accident; and the risks facing the average smoker and average non-smoker. Smokers in the U.A.E., like smokers in the U.K., exhibited "constrained optimism." Non-smokers, unlike non-smokers in the U.K., were "pessimistic" about their chances of developing heart disease and having an accident. Eighty-two male doctors, 41 smokers and 41 non-smokers, were asked to respond to two hypothetical patients (one with long-term obesity newly diagnosed as being hypertensive, the other a long-term smoker newly diagnosed as having lung cancer). Compared with smoker doctors, doctors who themselves did not smoke expected to feel more uncomfortable when managing the smoker patient, and perceived him as more responsible for his condition. Possible reasons for these results, their implications and ways of pursuing the issues raised are discussed.

A proportionate mortality study of a cohort of golf course superintendents was conducted using death certificates for 686 deceased members of the Golf Course Superintendents Association of America who died from 1970 to 1992. White males were included in the study population from all 50 states. The study objective was to compare mortality from this cohort to the general U.S. white male population. The proportionate mortality ratio (PMR) for all types of cancer was 136 (CI: 121, 152). Significant excess mortality from smoking-related diseases was observed. The PMR for arteriosclerotic heart disease was 140, which was significantly elevated (CI: 127, 155). In addition, the PMR for all respiratory diseases was 176 (CI: 135,230), while the PMR for emphysema was 186 (CI: 101,342). The PMR for lung cancer was 117 (CI: 93, 148). Mortality for four cancer types--brain, lymphoma (non-Hodgkin's lymphoma, NHL), prostate, and large intestine--occurred at elevated levels within this cohort: brain cancer PMR = 234 (CI: 121,454), non-Hodgkin's lymphoma (NHL) PMR = 237 (CI: 137,410), prostate cancer PMR = 293 (CI: 187,460), and large intestine cancer PMR = 175 (CI: 125,245). The PMR for diseases of the nervous system was 202 (CI: 123,333). A similar pattern of elevated NHL, brain, and prostate cancer mortality along with excess deaths from diseases of the nervous system has been noted among other occupational cohorts exposed to pesticides.

The detailed mortality and morbidity statistics on smoking tend to conceal the overall impact of the habit on health. About 3 million people die each year from smoking in economically developed countries, half of them before the age of 70. Cancers of eight sites are recognized as being caused by smoking--lung cancer almost entirely and the others (upper respiratory, bladder, pancreas, oesophagus, stomach, kidney, leukaemia) to a substantial extent. Six other potentially fatal diseases are also judged to be caused by smoking: respiratory heart disease, chronic obstructive lung disease, stroke, pneumonia, aortic aneurysm and ischaemic heart disease, the most common cause of death in economically developed countries. Non-fatal diseases, such as peripheral vascular disease, cataracts, hip fracture, and periodontal disease, which cause appreciable disability, cost and inconvenience are also caused by smoking. In pregnancy, smoking increases the risk of limb reduction defects, spontaneous abortion, ectopic pregnancy, and low birth weight. While there are some diseases for which smoking shows a protective effect, the 'benefits' of these are negligible in relation to the illness and premature mortality caused by smoking. About 20% of all deaths in developed countries are caused by smoking; an enormous human cost which can be completely avoided.

Because of their occupational exposure to a variety of toxic agents, fire fighters may be at risk for a number of exposure-related diseases. We reviewed the current literature on disease risk among fire fighters to compare findings and to infer magnitude of risk. A standard mortality ratio (SMR) of 200 is equal to an attributable risk of 100% of expected, sufficient to justify presumption in most workers' compensation systems that accept this. We therefore concentrated on risks that approach or exceed an SMR of 200 or an equivalent risk estimate, bearing in mind that confidence intervals around these estimates are wide. Based on the criteria for presumption of occupational risk, we suggest the following conclusions with respect to general presumption of risk: (1) Lung cancer: There is evidence for an association but not of sufficient magnitude for a general presumption of risk. (2) Cardiovascular. There is no evidence for an increased risk of death overall from heart disease. Sudden death, myocardial infarction, or fatal arrhythmia occurring on or soon after near-maximal stress on the job are likely to be heart related, but such "heart attacks" occurring away from work cannot be presumed to be work related. (3) Aortic aneurysm: The evidence is incomplete for an association, but if an association does exist, it would probably be of a magnitude compatible with a general presumption of risk. (4) Cancers of the genitourinary tract, including kidney, ureter, and bladder: The evidence is strong for both an association and for a general presumption of risk. (5) Cancer of brain: Incomplete evidence strongly suggests a possible association at a magnitude consistent with a general presumption of risk. (6) Cancer of lymphatic and hematopoietic tissue: By group, there is some evidence for both an association and a general presumption or risk. However, the aggregation is medically meaningless. We therefore recommend a case-by-case approach. (7) Cancer of the colon and rectum: There is sufficient evidence to conclude that there is an association but not that there is a general presumption of risk. (8) Acute lung disease: Unusual exposures, such as exposure to the fumes of burning plastics, can cause severe lung toxicity and even permanent disability. This does not appear to result in an increased lifetime risk of dying from chronic lung disease.

We present fourteen patients with an abnormal extrapulmonary accumulation on lung perfusion scintigraphy with 99mTc-macroaggregated albumin (MAA), who were examined during the last decade. These included six patients with lung cancer, four with pulmonary arterio-venous fistula, two with congenital heart disease, one with inferior vena cava (IVC) syndrome and one with congenital bronchogenic cyst. All six patients with lung cancer had superior vena cava (SVC) syndrome, and the tumor invaded the thoracic wall. As causes of abnormal accumulation, fourteen patients had a right-to-left shunt, and one patient with IVC syndrome had a systemic vein-to-portal vein shut, and one patient with lung cancer associated with superior vena cava (SVC) syndrome had both right-to-left and systemic vein-to-portal vein shunts. In the two patients with systemic vein-to-portal vein shunts, a hot spot was observed at the hepatic hilum, and radionuclide venography revealed remarkably developed collateral pathways to the portal vein. An extrapulmonary accumulation seen on 99mTc-MAA lung perfusion scan therefore indicates the existence of unusual hemodynamics with a shunt. We should therefore be careful not to overlook this peculiar finding.

This paper reports the mortality experience from 1948 to 1989 of 2,504 maintenance employees who had a minimum of one year of employment in jobs with potential exposure to asbestos at a Texas refinery and petrochemical plant. For the purposes of this study, "potential exposure" is equated with those jobs or crafts having the greatest direct potential proximity to, or which worked directly with, asbestos-containing materials, especially asbestos-containing thermal insulation. Approximately one-half of the study population had 10 years or longer potential exposure, and 80% had their first potential exposure before 1970. The total population exhibited significantly lower mortality for all causes, the standardized mortality ratio (SMR = 77); and for all cancer (SMR = 85), as compared to residents in the surrounding communities. Statistically significant deficits in mortality were also observed in a number of noncancerous diseases such as heart disease (SMR = 78; 95% CI = 69-88), nonmalignant respiratory disease (SMR = 70; 95% CI = 50-95), and cirrhosis of the liver (SMR = 44; 95% CI = 22-79). Mortality among employees who had 20 years or longer since their first potential exposure was also examined; the pattern of mortality was similar to that exhibited by the total cohort, with a slight increase in the SMR for most of the causes. The only statistically significant excess of mortality found was a fourfold increase in mesothelioma (5 observed and 1.2 expected deaths) the SMR was 428 (95% CI = 139-996) for the total cohort and was 469 (95% CI = 152-1093) for those who had 20 years or more since first potential exposure. In contrast to asbestos industry worker studies, mortality for lung cancer was substantially lower than the general population (SMR = 81; 95% CI = 63-103). The observed number of deaths for cancer of the larynx was virtually the same as expected (3 observed vs. 2.8 expected). This study also showed decreased mortality for cancers of gastrointestinal organs such as the esophagus (SMR = 78), stomach (SMR = 63), large intestine (SMR = 91), rectum (SMR = 55), or pancreas (SMR = 90)--cancers that have been reported to be elevated in studies of various industry workers directly exposed to asbestos.

In response to a request for information on indoor air quality problems, the U.S. Occupational Health and Safety Administration (OSHA) has proposed a rule addressing indoor air quality in general, and especially environmental tobacco smoke (ETS), in indoor work environments. As justification for the proposed rule, OSHA relies on a quantitative risk assessment used to provide estimates of lifetime risk of lung cancer and heart disease associated with workplace exposure to ETS. However, there are a number of concerns regarding the OSHA risk assessment. (i) The form of the underlying mathematical model used in the risk assessment is inappropriate. (ii) OSHA was highly selective in choosing what data values to use in their risk assessment. (iii) Many data values required as input to the OSHA risk assessment model are simply not known at this time. When such values are required, known, but possibly inappropriate, values were substituted. The conclusions arrived at by OSHA on the basis of this risk assessment seem unwarranted.

Reported Relative Risks associated with smoking differ between studies; these differences may reflect true biological differences between populations or may be research artifacts introduced by differences in factors such as amount smoked or smoking duration. The authors reviewed the literature published before June 1992 on relative risks associated with smoking for heart disease, stroke, lung cancer, and chronic obstructive lung disease. They quantified the effect of variables such as age, amount smoked, and smoking duration on reported relative risks. The main reasons for the variation in reported relative risks were: misclassification of former smokers as never smokers, the use of mortality rate ratios rather than incidence rate ratios, a possible period effect suggesting increasing relative risks over time, and differences in the amounts smoked. It is far more likely that these factors are responsible for the observed variation between studies than that the variations reflect true biological differences between populations. Using relative risks from other studies is therefore justified in calculating a population attributable risk if the studies are carefully selected and address factors such as amount smoked and period effects.

Since the mid-1960s, the proportion of deaths from the leading cause of U.S. mortality, heart disease, has decreased fairly steadily. The proportion of cancer deaths has risen over the same period, however, from 16.3 percent in 1965 to 23.7 in 1991. Public awareness of this increase has resulted in questions being raised about the probability of developing or dying of cancer. Analyses of published data in the 1973-1991 Surveillance, Epidemiology and End Results (SEER) program of the National Cancer Institute estimated a person's lifetime risk of developing or dying of cancer. The lifetime risk of developing cancer is 44.8 percent for men and 39.3 percent for women. For both sexes, the risk of dying of lung cancer is higher than for any other cancer.
