Smoking is a high-risk behaviour affecting health and economic welfare of society. Thus it is important to quantify the economic burden smoking places on social institutions in Germany. Approximately 33.4% of the male and 20.4% of the female population are current smokers. This study investigates the health care costs of smoking based on 1996 figures, focusing on the seven most frequent diseases associated with the inhalation of tobacco smoke: chronic obstructive pulmonary disease (COPD, international classification of diseases (ICD) 490-491); lung cancer (ICD 162); stroke (ICD 434-438); coronary artery disease (ICD 410-414); cancer of the mouth and larynx (ICD 140-149, 161) and artherosclerotic occlusive disease (ICD 440). A data search was carried out on MEDLINE, the German Institute for Medical Documentation and Information, and the Internet as well as in databases of health insurance companies and the German Federal institute of statistics. Direct and indirect costs were calculated separately. The results estimate the total smoking related health care costs (attributable fraction due to smoking) for COPD to be 5.471 billion EURO (73%), for lung cancer 2.593 billion EURO (89%), for cancer of the mouth and larynx 0.996 billion EURO (65%), for stroke 1.774 billion EURO (28%), for coronary artery disease 4.963 billion EURO (35%) and for atherosclerotic occlusive disease 0.761 billion EURO (28%). The economic burden of smoking related health care costs for Germany is 16.6 billion EURO. Smoking is therefore responsible for 47% of the overall costs of these diseases (35.2 billion EURO). In the view of the high costs for smoking, of which almost 50% are due to respiratory disease, pneumologists should enhance their effort in primary, secondary and tertiary prevention.

It is known that prostaglandin E1 (PGE1) is a potent vasodilator and improves red cell deformability. Single lung-ventilation sometimes occurs under lung transplantation, lung cancer surgery and traumatic pneumonectomy, and may result in increased pulmonary resistance, right heart failure and severe hypoxemia. The present experimental study was undertaken to examine the effects of PGE1 on these states induced by single-lung ventilation and hypoventilation. Fourteen pigs weighing 32-33 kg were anesthetized, intubated and ventilated using a respirator and then randomly assigned to two groups, the control group and the PGE1 treated group, 7 pigs each. After median sternotomy to induce severe hypoxemia hypoventilation was induced and then the right hilus pulmonis was cross clamped. Mean blood pressure, mean pulmonary arterial pressure (PAP), pulmonary vessel resistance (PVR), right ventricular stroke work (RVSW) and arterial blood gases (PaO2 and SatO2) were measured at baseline, in the hypoventilation state, and 15 min, 1 hour, and 2 hours after the right hilus pulmonis clamping with hypoventilation. PGE1 (250 microg/20 ml saline) was administered via the central vein starting 15 min after right hilus cross clamping for 1 hour and 45 min in the PGE1 group. PGE1 significantly reduced PAP and PVR, normalized RVSW, and improved PaO2. PGE1 may be useful for the condition of increased pulmonary hypertension during single-lung ventilation and hypoventilation.

There has been a substantial decline in mortality in Australia during the 20th century, with a major improvement in life expectancy. There has been a broad "health transition", from a pattern of high mortality from infectious diseases to one of lower overall mortality from non-communicable diseases and injury. From 1951, trends in death rates from major causes were evident, with the rise and partial fall of two epidemics (coronary heart disease and stroke, and lung cancer). This overall picture masks significant inequalities in health for Indigenous people and the socioeconomically disadvantaged.

Smoking is the leading preventable cause of premature death and disability in Canadian women. Lung cancer, ischemic heart disease, chronic obstructive lung disease, and stroke account for two-thirds or more of the smoking-attributable deaths in women. Lung cancer now exceeds breast cancer as the leading cause of cancer death in women, and both incidence and mortality rates continue to climb. Strong evidence suggests that for the same number of cigarettes smoked, women are more susceptible than men to the carcinogenic effects on their lungs. Evidence also is growing that lung function in women is more adversely affected by smoking and that smoking may be a stronger risk factor for myocardial infarction in women than it is in men. More research into the mechanisms underlying these gender-related susceptibilities is needed. Policies and programs to prevent girls from starting to smoke and to facilitate quitting in women of all ages must be public health priorities.

Mortality was analyzed for an automotive engine foundry and machining complex, with process exposures derived from department assignments. Logistic regression models of mortality odds ratios (ORs) were calculated for 2546 deaths, and numbers of work-related deaths were estimated. Lung cancer mortality in the foundry was increased where cleaning and finishing of castings was performed (OR, 1.7; 95% CI, 1.15 to 2.4 [at mean exposure duration of exposed cases]) and in care-making after 1967 (OR, 1.5; 95% CI, 1.11 to 2.0). Black workers had excess lung cancer mortality in machining heat-treat operations (OR, 2.5, 95% CI, 1.4 to 4.3) and excess nonmalignant respiratory disease mortality in molding (OR, 2.5; 95% CI, 1.16 to 5.5) and core-making (OR, 2.7; 95% CI, 1.25 to 5.8). Stomach cancer mortality was elevated among workers with metalworking fluid exposures in precision grinding (OR, 2.4; 95% CI, 1.14 to 5.1). Heart disease mortality was increased among all workers in molding (OR, 1.6; 95% CI, 1.09 to 2.3), as was stroke mortality among workers exposed to metalworking fluids (OR, 1.8; 95% CI, 1.22 to 2.7). Malignant and nonmalignant liver disease mortality was elevated in assembly/testing and precision grinding. In this modern foundry, 11% of deaths were estimated to be work-related despite it's being largely in regulatory compliance over its 40-year existence. Machining plant exposures accounted for 3% or more of deaths there.

This article aimed to estimate the mortality from exposure to passive smoking at work in Finland. The estimation used statistics on causes of death, exposure prevalences, and risk ratios from epidemiologic studies. The attributable fractions of cause-specific mortality from passive smoking at work were 2.8% for lung cancer, 1.1% for chronic obstructive pulmonary disease, 4.5% for asthma, 3.4% for ischemic heart disease, and 9.4% for cerebrovascular stroke. Altogether, about 250 fatalities were estimated to have occurred in 1996. This is approximately 0.9% of the total mortality in the Finnish population in the relevant disease and age categories. The magnitude of mortality related to past occupational exposure to passive smoking is considerable. Preventive measures to reduce environmental tobacco smoke in the workplace will be a powerful means of reducing the high burden of respiratory and cardiovascular diseases.

This paper briefly reviews the health hazards associated with smoking, including passive smoking, with specific reference to local (Hong Kong) evidence. A Medline search of Hong Kong papers from January 1966 to January 1998 was made, and these and other relevant papers were reviewed. In Hong Kong, at least 10 people die daily from smoking- related diseases. Local studies show that smoking is associated with lung cancer, oesophageal cancer, liver cancer, ischaemic heart disease, peripheral vascular disease, ischaemic stroke, peptic ulcer, osteoporosis, impaired lung function, respiratory symptoms, and other adverse health effects. Smoking in pregnant women can result in smaller babies being born. Pooled results from four case-control studies show a 60% excess risk of lung cancer due to exposure to environmental tobacco smoke. Several studies confirm the link between exposure to environmental tobacco smoke and respiratory illness, hospitalisation, and asthma in children. The risks of smoking (one of every two smokers will be killed by tobacco) are not well known and are underestimated by both doctors and the public. Stronger health messages and more local evidence are needed to support tobacco control in Hong Kong.

A 68-year-old man was admitted to St Marianna University Hospital on account of loss of consciousness with left hemiplegia. During the hospital recovery course with a rehabilitation procedure, the patient's blood pressure was very unstable, fluctuating between high (210/110 mmHg) and low (110/70 mmHg) values accompanied by a fainting sensation. A second stroke of left hemiplegia took place 1 month later. Afterwards, his condition worsened to tetraplegia with dysarthria. Three months later, lung cancer with multiple metastasis including his left neck was found and he died from adynamic ileus 6 months after the onset of the present illness. Autopsy revealed nearly complete atheromatous obstruction and more than 50% stenosis, respectively, of his right common and internal/external carotid arteries. His intracranial arterial trunks and main branches were all patent with localized atherosclerosis of only moderate degree. The pathology of the brain existed predominantly in the right hemisphere in the border zone area between the anterior and middle cerebral arteries systematically with numerous disseminated foci of complete or incomplete necrosis, white matter and gray matter being involved independently. Involvement of centrum semiovale white matter is more extensive and intensive than that of gray matter. Of the gray matter, cerebral cortex as well as striatum, periventricular (the third ventricle) gray and cerebellar cortex was involved. The specific characteristic topography and distribution of the lesions together with their histopathology are described in detail with illustration. It is concluded that this case represents an outstanding example of hemodynamic cerebral circulatory insufficiency doubly caused by hemilateral carotid artery stenosis and repeated episodes of systemic hypotension.

The aims of this article are to synthesize the evidence on health effects of environmental tobacco smoke (ETS) in the elderly and to discuss questions for future research. Health effects are divided into aetiological and prognostic studies. There is convincing evidence that ETS causes lung cancer and coronary heart disease, both of which are diseases of the elderly. Several cross-sectional studies show increased occurrence of chronic respiratory symptoms and deficits in ventilatory lung function in relation to ETS exposure at home and/or at work. A limited number of studies have found significant relations between ETS exposure and asthma, chronic obstructive pulmonary disease (COPD), pneumococcal infections and stroke in the elderly. Longitudinal studies are needed before any definite conclusions can be made concerning ETS and noncarcinogenic respiratory diseases in the elderly. The potential role of environmental tobacco smoke exposure as a prognostic factor determining development of a pre-existing respiratory or heart disease is an important new area for research.

John Hutchinson, a surgeon, recognized that the volume of air that can be exhaled from fully inflated lungs is a powerful indicator of longevity. He invented the spirometer to measure what he called the vital capacity, ie, the capacity to live. Much later, the concept of the timed vital capacity, which became known as the FEV(1), was added. Together, these two numbers, vital capacity and FEV(1), are useful in identifying patients at risk of many diseases, including COPD, lung cancer, heart attack, stroke, and all-cause mortality. This article cites some of the rich history of the development of spirometry, and explores some of the barriers to the widespread application of simple spirometry in the offices of primary care physicians.
