The overall improvement in the health of Americans over the 20th century is best exemplified by dramatic changes in 2 trends: 1) the age-adjusted death rate declined by about 74%, while 2) life expectancy increased 56%. Leading causes of death shifted from infectious to chronic diseases. In 1900, infectious respiratory diseases accounted for nearly a quarter of all deaths. In 1998, the 10 leading causes of death in the United States were, respectively, heart disease and cancer followed by stroke, chronic obstructive pulmonary disease, accidents (unintentional injuries), pneumonia and influenza, diabetes, suicide, kidney diseases, and chronic liver disease and cirrhosis. Together these leading causes accounted for 84% of all deaths. The size and composition of the American population is fundamentally affected by the fertility rate and the number of births. From the beginning of the century there was a steady decline in the fertility rate to a low point in 1936. The postwar baby boom peaked in 1957, when 123 of every 1000 women aged 15 to 44 years gave birth. Thereafter, fertility rates began a steady decline. Trends in the number of births parallel the trends in the fertility rate. Beginning in 1936 and continuing to 1956, there was precipitous decline in maternal mortality from 582 deaths per 100 000 live births in 1935 to 40 in 1956. Since 1950 the maternal mortality ratio dropped by 90% to 7.1 in 1998. The infant mortality rate has shown an exponential decline during the 20th century. In 1915, approximately 100 white infants per 1000 live births died in the first year of life; the rate for black infants was almost twice as high. In 1998, the infant mortality rate was 7.2 overall, 6.0 for white infants, and 14.3 for black infants. For children older than 1 year of age, the overall decline in mortality during the 20th century has been spectacular. In 1900, >3 in 100 children died between their first and 20th birthday; today, <2 in 1000 die. At the beginning of the 20th century, the leading causes of child mortality were infectious diseases, including diarrheal diseases, diphtheria, measles, pneumonia and influenza, scarlet fever, tuberculosis, typhoid and paratyphoid fevers, and whooping cough. Between 1900 and 1998, the percentage of child deaths attributable to infectious diseases declined from 61.6% to 2%. Accidents accounted for 6.3% of child deaths in 1900, but 43.9% in 1998. Between 1900 and 1998, the death rate from accidents, now usually called unintentional injuries, declined two-thirds, from 47. 5 to 15.9 deaths per 100 000. The child dependency ratio far exceeded the elderly dependency ratio during most of the 20th century, particularly during the first 70 years. The elderly ratio has gained incrementally since then and the large increase expected beginning in 2010 indicates that the difference in the 2 ratios will become considerably less by 2030. The challenge for the 21st century is how to balance the needs of children with the growing demands for a large aging population of elderly persons.

Atherosclerosis is manifested as coronary artery disease (CAD), ischemic stroke and peripheral vascular disease. Moderate alcohol consumption has been associated with reduction of CAD complications. Apparently, red wine offers more benefits than any other kind of drinks, probably due to flavonoids. Alcohol alters lipoproteins and the coagulation system. The flavonoids induce vascular relaxation by mechanisms that are both dependent and independent of nitric oxide, inhibits many of the cellular reactions associated with atherosclerosis and inflammation, such as endothelial expression of vascular adhesion molecules and release of cytokines from polymorphonuclear leukocytes. Hypertension is also influenced by the alcohol intake. Thus, heavy alcohol intake is almost always associated with systemic hypertension, and hence shall be avoided. In individuals that ingest excess alcohol, there is higher risk of coronary occlusion, arrhythmias, hepatic cirrhosis, upper gastrointestinal cancers, fetal alcohol syndrome, murders, sex crimes, traffic and industrial accidents, robberies, and psychosis. Alcohol is no treatment for atherosclerosis; but it doesn't need to be prohibited for everyone. Thus moderate amounts of alcohol (1-2 drinks/day), especially red wine, may be allowed for those at risk for atherosclerosis complications.

Arterial function may be altered in patients with cirrhosis. We determined compliance of the arterial tree (C(1)) in relation to systemic and splanchnic hemodynamic derangement and clinical variables. C(1) and the stroke volume-pulse pressure index (SV/PP) were significantly higher (+62% and +40%, respectively; P < 0.001) in cirrhotic patients (n = 49) than in control subjects (n = 19), and a close correlation between C(1) and SV/PP was found in both cirrhotic patients (r = 0.86, P < 0.001) and control subjects (r = 0.96, P < 0.001). Univariate analysis showed significant relations between C(1) and SV/PP on one side and age, sex, body weight, portal pressure, systemic hemodynamics, biochemical variables, and severity of disease on the other. In the multiple-regression analysis, sex, age, mean arterial blood pressure, systemic vascular resistance, and biochemical variables were significant independent predictors of SV/PP (P < 0.005-0.00001). In conclusion, arterial compliance is elevated in cirrhosis. A simplified SV/PP index seems to reflect abnormalities in the arterial compliance of these patients.

Several issues should be addressed when managing women with Turner's syndrome. Female sex hormone substitution should be offered to help prevent the increased morbidity seen in Turner's women, which consists of an increased risk of fractures and osteoporosis, and a clustering of diseases such as ischaemic heart disease, hypertension, stroke and type 2 diabetes, the latter entities being part of the insulin resistance syndrome. Furthermore, hypothyroidism is often seen, and the risk of type 1 diabetes may also be increased. Congenital malformations of the heart are frequently seen in Turner's syndrome, possibly increasing the risk of dissecting aorta aneurysm. Liver enzymes are often elevated and there may be an increased risk of liver cirrhosis. Mortality seems to be increased in Turner's syndrome, women with the "pure" 45,X karyotype being the most severely affected. In clinical practice, careful monitoring of glucose and bone metabolism, weight, thyroid function and blood pressure should be carried out. A cardiovascular risk profile should be determined and the patient informed of the risks and benefits of sex hormone replacement therapy. Sex hormone replacement therapy is highly recommended, although at present there are no longitudinal data documenting the long-term positive effect of sex steroid substitution. However, hypogonadism is expected to explain at least part of the decreased lifespan found in Turner's syndrome. Since general physicians only encounter these patients infrequently, it is recommended that the care and treatment of Turner's syndrome be centralized.

Several issues have to be considered when taking care of girls and women with Turner syndrome. During childhood, short stature is the primary concern and treatment with growth hormone (GH) is now widely used, often in conjunction with the androgen, oxandrolone. Recent studies indicate that doses used previously in the treatment of short stature have been too small. Induction of puberty should be performed at an appropriate age with reference to the peers of the patient. In adulthood, female sex hormone substitution should be offered to possibly prevent the increased morbidity seen in Turner syndrome, which consists of increased risk of fractures and osteoporosis, a clustering of diseases like ischaemic heart disease, hypertension, stroke and Type 2 diabetes, the latter entities being involved in the insulin resistance syndrome. Furthermore, hypothyreosis are often seen and the risk of Type 1 diabetes may also be increased. Congenital malformations of the heart are frequently seen in Turner syndrome, possibly increasing the risk of dissecting aorta aneurism. Liver enzymes are often elevated in Turner syndrome and there may be an increased risk of cirrhosis of the liver. Mortality does seem to be increased in Turner syndrome and women with the 'pure' 45,X karyotype do seem to be most severely affected. In the clinical practice of Turner syndrome, a careful monitoring of glucose and bone metabolism, weight, thyroid function and blood pressure should be performed. A cardiovascular risk profile should be determined and the patient informed concerning risks and benefits from sex hormone replacement therapy. Based on the available literature, sex hormone replacement therapy is highly recommended, although at present there are no longitudinal data documenting the long-term positive effect of sex steroid substitution. However, hypogonadism is expected to explain at least part of the decreased lifespan found in Turner syndrome. Since general physicians encounter Turner patients infrequently, it is recommended that the care and treatment of Turner syndrome is centralised.

Much published research documents continuing racial and ethnic disparities in health, particularly for African Americans, which apply to both oral and systemic diseases. Current research suggests biologically plausible associations between oral and systemic diseases; however, clear cause-and-effect relationships have not been substantiated. Some researchers and health care providers have noted anecdotal associations between oral and systemic health, as well as compounding adverse effects of oral and systemic diseases and dysfunctions. Historically, African American physicians, dentists, and pharmacists have bonded together under one organizational umbrella to combat discrimination, prejudice, and racism directed at them and their patient populations. This coming together has resulted in a more comprehensive clinical, behavioral, economic, and public health decision-making process related to the general health and well-being of their patient populations, such as maximizing health care visits, treatment plans, reimbursements, and oral and systemic health care follow-ups. According to the 1985 Secretary's Task Force Report, the six causes of excess deaths among African Americans were: cardiovascular disease and stroke; cancer; diabetes; cirrhosis; homicide and accidents; and infant mortality. In 1991, HIV/AIDS became the seventh cause of excess deaths. This article summarizes salient information about cardiovascular diseases, diabetes, cancer, and the social and behavioral factors related to oral and systemic health.

In patients with cirrhosis and portal hypertension, standing induces a reduction in cardiac index (CI) and an increase in systemic vascular resistance index. Our previous studies indicate that this abnormal hemodynamic response to standing is due to an altered myocardial function, because cirrhotic patients are unable to compensate for the reduced preload with an increase in left ventricular (LV) ejection fraction (EF) and stroke volume. To evaluate whether the cardiac dysfunction in cirrhosis is influenced by canrenone, an aldosterone antagonist, 8 patients with preascitic, nonalcoholic cirrhosis, and portal hypertension underwent echocardiographic assessment of LV function and systemic hemodynamics and determinations of plasma volume, urinary sodium excretion, and plasma renin activity (PRA), aldosterone (PAC), and norepinephrine (PNE) when on a 150-mmol/d-sodium diet (baseline), after 1 month on canrenone (100 mg/d) plus a 40-mmol/d-sodium diet and after 1 month on canrenone plus a 150-mmol/d-sodium diet. Echocardiographic evaluation was performed with the patient in the supine position and during active standing. At baseline, patients had high plasma volume and normal renal function, PRA, PAC, and PNE. CI, LVEF, and stroke volume index were also normal. Standing caused a significant reduction in CI and LVEF. After canrenone and either sodium diet, CI significantly decreased, and PRA and PNE increased in the supine position. On standing, LVEF and CI did not decrease further. Plasma volume significantly decreased only after low-sodium diet plus canrenone. In conclusion, canrenone normalizes the cardiac response to the postural challenge in patients with preascitic cirrhosis.

There is abundant epidemiological and clinical evidence showing that light-moderate drinking is associated with a reduced risk of coronary heart disease (CHD), total and ischaemic stroke and total mortality in middle-aged and elderly men and women. The epidemiological evidence suggests a J- or U-shaped relationship between alcohol and CHD. However, the apparent benefits of moderate drinking on CHD mortality are offset at higher drinking levels by increasing risk of death from other types of heart diseases (cardiomyopathy, arrhythmia etc.), neurological disorders, cancer, liver cirrhosis, and traffic accidents. The plausible mechanisms for the putative cardioprotective effects include increased levels of high-density lipoprotein cholesterol, decreased levels of low-density lipoprotein cholesterol, prevention of clot formation, reduction in platelet aggregation, and lowering of plasma apolipoprotein(a) concentration. Thus, alcohol reduces the risk of coronary vascular diseases both by inhibiting the formation of atheroma and decreasing the rate of blood coagulation.

Alcohol abuse ranks among the most common and severe environmental hazards to human health. Alcohol is a dependence producing drug and this dependence is associated with an increased risk of morbidity and mortality. While the social and behavioural consequences of alcoholism including psychiatric disorders are staggering, the manifestation of alcohol-related diseases is the most widespread somatic effect. In research conducted both at the social and individual level, alcohol was found to increase the risk of death from a number of specific causes, including injury from traffic accidents and other trauma, violence, suicide, liver cirrhosis, cancer of the liver, breast cancer, haemorrhagic stroke, alcoholic psychosis, alcohol dependence and chronic pancreatitis. The apparent beneficial effect of modest alcohol consumption (one to three drinks per day) on mortality and morbidity rates particularly relating to cardiovascular disease on the other side are of recent interest. Public health policy should aim at reducing the harm done by alcohol use, whilst recognizing its perceived and possible real benefits. The aim of this review is to introduce the reader to the definition of alcohol dependence and alcoholism, and summarize our knowledge about the effects of alcohol consumption on the gastrointestinal tract.

The aim of this study was to evaluate the efficacy and safety of oral sildenafil to treat erectile dysfunction (ED) in chronic renal failure in patients on hemodialysis (HD). A double-blind, randomized, placebo-controlled study of oral sildenafil (50 mg) administered as required in HD patients with ED was designed. Patients on HD for at least 6 mo and who had a stable relationship with a female sexual partner were included. Patients older than 70 yr with penile anatomic abnormalities, cirrhosis, diabetes, angina, severe anemia, and those who were on nitrate treatment or with a recent history of stroke or myocardial infarction were not included. The International Index of Erectile Dysfunction (IIEF) was employed to evaluate ED and treatment response. Forty-one patients were evaluated (21 received placebo, and 20 sildenafil). Baseline clinical and demographic parameters were similar in both groups. Sildenafil was associated with improvement in the score of all questions and domains of the IIEF, except those related to sexual desire. Using the erectile function domain to evaluate primary efficacy, improvement was observed in 85% of the sildenafil patients compared with 9.5% of placebo patients. Sildenafil use resulted in normal EF scores in 35% of sildenafil patients. Sildenafil was well tolerated. Headaches and flushing occurred in both groups. Dyspepsia was reported by two patients in the sildenafil group. In conclusion, oral sildenafil seems to be an effective and safe treatment for ED in selected patients with chronic renal failure on hemodialysis.
