An extensive body of data shows concordant J-shaped associations between alcohol intake and a variety of adverse health outcomes, including coronary heart disease, diabetes, hypertension, congestive heart failure, stroke, dementia, Raynaud's phenomenon, and all-cause mortality. Light to moderate alcohol consumption (up to 1 drink daily for women and 1 or 2 drinks daily for men) is associated with cardioprotective benefits, whereas increasingly excessive consumption results in proportional worsening of outcomes. Alcohol consumption confers cardiovascular protection predominately through improvements in insulin sensitivity and high-density lipoprotein cholesterol. The ethanol itself, rather than specific components of various alcoholic beverages, appears to be the major factor in conferring health benefits. Low-dose daily alcohol is associated with better health than less frequent consumption. Binge drinking, even among otherwise light drinkers, increases cardiovascular events and mortality. Alcohol should not be universally prescribed for health enhancement to nondrinking individuals owing to the lack of randomized outcome data and the potential for problem drinking.

Survivors of ischemic stroke are at significant risk for recurrent stroke. Appropriate therapy for stroke prevention is needed given the significant morbidity and mortality associated with stroke, the high financial costs, and the neurologic disability associated with treatment failure. A treatment strategy based on assessed risk represents an appropriate use of medical resources and results in improved outcomes. This approach requires evaluation of major risk factors, the most serious of which is a history of ischemic stroke or transient ischemic attack. The annual risk for recurrent stroke is 6% during the first 5 years after an initial stroke. Non-modifiable risk factors include age, race, ethnicity, gender, family history, and geography. The most important modifiable risk factor is hypertension. Diabetes mellitus, hyperlipidemia, left ventricular hypertrophy, atrial fibrillation, and lifestyle factors such as smoking, alcohol abuse, and obesity contribute to stroke risk. Antihypertensive, lipid-lowering, and antiplatelet therapies have been successful in reducing the incidence of secondary stroke. Clinical trials validate the benefits of statin therapy in reducing the risk for secondary stroke. Studies of antiplatelet agents, including aspirin, clopidogrel, and aspirin combined with extended-release dipyridamole, have evaluated the risk reduction in recurrent stroke and have been concerned particularly with the risk for hemorrhage. Therapy for stroke prevention based on risk stratification can identify patients who are appropriate targets for aggressive intervention.

Nonalcoholic fatty liver disease (NAFLD) is a group of diseases with excess fat in liver in the absence of a poorly defined limit of alcohol consumption. Most common variety, a universal public health problem, is associated with insulin resistance caused by a host of genetic and epigenetic defects modulated by life style and environmental factors. In fact the term NAFLD is loose to incorporate so many etiologies except alcoholism and few other etiologies, presenting as fat in liver. However as a sign fatty liver is very important in predicting the risk of diabetes, cardiovascular disease, stroke, cirrhosis and cancer. Abnormal fat accumulation can result from several defects in nuclear receptors associated with lipid sensing, synthesis and oxidation like LXR, FXR, SREBP, ChREBP and PPAR; defects in the lipid influx-efflux channels, insulin signaling, proteins involved in fatty acid catabolism, defects in adipose tissue development and function, inappropriate nutrition and finally defects in neural regulatory mechanisms. The progress of the disease is determined by the basic defects which results in fat accumulation, an individual's immunological response to the accumulated fat and its derivatives and the oxidant stress response. Congregation of unrelated genetic defects under same diagnosis 'NAFLD' can result in inefficient patient management. Further studies are required to understand the molecular basis of fatty liver to enable a personalized management of diseases presenting as fatty liver in the absence of alcohol abuse.

The objective of this study was to present nationally representative findings on sociodemographic and psychopathologic predictors of first incidence of Diagnostic and Statistical Manual of Mental Disorders, 4th edn (DSM-IV) substance, mood and anxiety disorders using the Wave 2 National Epidemiologic Survey on Alcohol and Related Conditions. One-year incidence rates of DSM-IV substance, mood and anxiety disorders were highest for alcohol abuse (1.02), alcohol dependence (1.70), major depressive disorder (MDD; 1.51) and generalized anxiety disorder (GAD; 1.12). Incidence rates were significantly greater (P<0.01) among men for substance use disorders and greater among women for mood and anxiety disorders except bipolar disorders and social phobia. Age was inversely related to all disorders. Black individuals were at decreased risk of incident alcohol abuse and Hispanic individuals were at decreased risk of GAD. Anxiety disorders at baseline more often predicted incidence of other anxiety disorders than mood disorders. Reciprocal temporal relationships were found between alcohol abuse and dependence, MDD and GAD, and GAD and panic disorder. Borderline and schizotypal personality disorders predicted most incident disorders. Incidence rates of substance, mood and anxiety disorders were comparable to or greater than rates of lung cancer, stroke and cardiovascular disease. The greater incidence of all disorders in the youngest cohort underscores the need for increased vigilance in identifying and treating these disorders among young adults. Strong common factors and unique factors appear to underlie associations between alcohol abuse and dependence, MDD and GAD, and GAD and panic disorder. The major results of this study are discussed with regard to prevention and treatment implications.

Alcohol dependence and alcohol abuse or harmful use cause substantial morbidity and mortality. Alcohol-use disorders are associated with depressive episodes, severe anxiety, insomnia, suicide, and abuse of other drugs. Continued heavy alcohol use also shortens the onset of heart disease, stroke, cancers, and liver cirrhosis, by affecting the cardiovascular, gastrointestinal, and immune systems. Heavy drinking can also cause mild anterograde amnesias, temporary cognitive deficits, sleep problems, and peripheral neuropathy; cause gastrointestinal problems; decrease bone density and production of blood cells; and cause fetal alcohol syndrome. Alcohol-use disorders complicate assessment and treatment of other medical and psychiatric problems. Standard criteria for alcohol dependence-the more severe disorder-can be used to reliably identify people for whom drinking causes major physiological consequences and persistent impairment of quality of life and ability to function. Clinicians should routinely screen for alcohol disorders, using clinical interviews, questionnaires, blood tests, or a combination of these methods. Causes include environmental factors and specific genes that affect the risk of alcohol-use disorders, including genes for enzymes that metabolise alcohol, such as alcohol dehydrogenase and aldehyde dehydrogenase; those associated with disinhibition; and those that confer a low sensitivity to alcohol. Treatment can include motivational interviewing to help people to evaluate their situations, brief interventions to facilitate more healthy behaviours, detoxification to address withdrawal symptoms, cognitive-behavioural therapies to avoid relapses, and judicious use of drugs to diminish cravings or discourage relapses.

The effects of alcoholic beverages on the cardiovascular system can take opposite forms, depending on how much of ethanol is consumed. The negative effects of alcoholism are well established. Alcoholism is a cause of cardiomyopathy, cardiac arrhythmias and hypertension. The best argument is the situation of Russian Federation where extremely high alcohol consumption caused very high ischemic heart disease and stroke mortality both in male and female population. On the other side there are also many proofs of health benefits of moderate alcohol consumption. The National Institute on Alcohol Abuse and Alcoholism in USA has completed an extensive review of current scientific knowledge about the health effects of moderate alcohol consumption: the lowest death rate from all causes occurs at the level of one drink per day. Moderate drinkers have the greatest longevity. Higher serum levels of high density lipoproteins (HDL) in moderate alcohol drinkers are associated with reduced risk for the development of atherosclerotic disease. HDL particles are believed to be antiatherogenic due to their capacity to drive reverse cholesterol transport and to antagonize pathways of inflammation, thrombosis, and oxidation (Fig. 4, Ref. 34).

Ephedra is an amphetamine-like compound with a potent sympathomimetic effect. Ephedrine, its active component, is widely used for weight loss, to enhance athletic performance or as component of some drugs. Its cardiovascular effects include tachycardia, increased inotropy, arterial vasoconstriction and hypertension, and these are the effects for which it is used therapeutically. However, it can also cause adverse effects, such as neuropathy, myopathy, psychosis, addiction, stroke, insomnia, myocarditis, arrhythmias, myocardial infarction or sudden death. We present the case of a patient, with pre-existing psychiatric conditions, who developed congestive heart failure and pulmonary oedema in the context of severe biventricular dysfunction and myocardial necrosis secondary to longstanding ephedrine abuse. Secondary causes of dilated myocardiopathy such as alcohol abuse, autoimmunity, hemochromatosis, thyroid alterations, viral or bacterial myocarditis and coronary heart disease, were ruled out. Five years after total cessation of use of the drug containing ephedrine, the patient is symptom-free, with partial recovery of left ventricular ejection fraction.

Background. The aim of this study was to investigate whether established risk factors for stroke in patients admitted to health care for first-ever stroke had been detected and treated in primary health care. Methods. In a retrospective study in Nacka municipality, Stockholm County, Sweden, with about 70 000 inhabitants, we included all men and women admitted to health care due to first-ever stroke between October 1999 and March 2001. Data on 187 such patients, with a mean age of 75 years, were obtained from medical registers. Main outcome measures were detection and treatment of risk factors for stroke including hypertension, diabetes, atrial fibrillation, smoking, alcohol abuse, and overweight/obesity. Results. In a majority of patients seen in primary health care with hypertension and diabetes, those risk factors were detected and treated (75.6% and 75.0%, resp.). Fewer patients with atrial fibrillation received treatment (60.9%). Treatment of lifestyle factors was difficult to assess because of lack of data in the medical records. Conclusions. Primary prevention of stroke in primary health care needs to be improved, especially when atrial fibrillation and lifestyle-related risk factors are present. Health policies need to target not only the public, but also general practitioners and other health care professionals.

Previous reports of comorbid conditions in poliomyelitis survivors mainly focused on some disease categories, such as respiratory diseases, gastrointestinal diseases, psychiatric diseases, neurological diseases and cancer. Data regarding a wide spectrum of medical comorbidities in patients with poliomyelitis is still sparse. This study aimed to investigate and profile the wide range of comorbidities among the survivors of paralytic poliomyelitis in a Chinese population. In total, 2,032 paralytic poliomyelitis patients were selected as the study group and the comparison group consisted of 10,160 randomly selected enrollees. The comorbidities for analysis were based on a modified version of the Elixhauser Comorbidity Index. Conditional logistic regression analyses were computed to investigate the risk of comorbidities for these two groups. As compared to controls, patients with paralytic poliomyelitis had significantly higher prevalence of hypertension, ischemic heart disease, hyperlipidemia, congestive heart failure, cardiac arrhythmias, peripheral vascular disorder, stroke, paralysis, migraines, Parkinson's disease, rheumatoid arthritis, ankylosing spondylitis, pulmonary circulation disorders, chronic pulmonary disease, liver disease, peptic ulcers, hepatitis B or C, deficiency anemias, depression, and lymphoma. Most of the differences are of clinical interest, ORs often being between 2 and 3. No significant difference between poliomyelitis patients and controls was observed in the prevalence of SLE, tuberculosis, alcohol abuse and drug abuse. Our findings demonstrate that survivors of paralytic poliomyelitis in Taiwan are at higher risk of having multiple medical comorbidities although some potential confounding factors including educational level, marital status, obesity and physical activity are not available in our database. The pattern is generally consistent with previous observations from Western populations. Nevertheless, we found several novel associations which have rarely, if ever, been reported previously.

Stroke is an increasing problem in sub-Saharan Africa, even in children. High rates of hypertension, diabetes, alcohol abuse, smoking, insufficient fruit and vegetable consumption, sickle cell disease, HIV infection, antiretroviral use and race are likely contributing factors. Although often considered as related to increasing wealth, stroke is more strongly related to poverty, and in turn increases it. Case-fatality rates are high and premature death and years of life lost are a major problem. We propose an approach to stroke prevention and treatment that takes into account the real situation on the ground and can be applied in sub-Saharan Africa, an area where stroke units are largely not feasible and many patients do not reach hospitals. Involvement of community and faith-based organisations, use of simple diagnostic tests, emphasis on clinical examination to differentiate between haemorrhagic and ischaemic stroke, prompt initiation of aspirin therapy and training of community nurses on essential management of stroke should be urgently implemented.
