Vascular dementia (VaD) is a heterogeneous pathology currently regarded as the result of a variety of causes. Different types of VaD can be identified according to different criteria. This heterogeneity might be one of the causes of the controversial results observed, up to now, in clinical trials. Recently, the 10th revision of the International Classification of Diseases (ICD-10) explicitly identified subcortical VaD as a well-defined subgroup. Abnormalities of white matter are clearly detectable with computed tomography or magnetic resonance scans. The clinicoradiological association of dementia, blood hypertension, and other vascular risk factors, extensive white matter lesions, and small subcortical infarcts might be considered as a clinical univocal entity. Following the encouraging results of a preliminary pilot study, the above-mentioned criteria were followed to define a population of patients to be enrolled in a double-blind, parallel-groups, placebo-controlled clinical trial with nimodipine, which has been proposed as a drug that can improve cognitive functions in patients with VaD. The paper discusses the protocol design of this ongoing trial and its main entry criteria, with particular emphasis on the definition of the population to be enrolled. Implication for future trials in subcortical VaD are discussed further.

Depression is more widespread than hypertension. Nevertheless, physicians specialized in family medicine did not have knowledge necessary to diagnose and treat depression and anxiety disorders. Only six persons out of fifty five who filled in the questionnaire could recognize depression correctly (ICD-10 criteria). Doctors knew antidepressant drugs, but they did not know therapeutic doses. We can try to explain this situation through doctor's pre and postgraduate education.

This paper aims at studying the development and the risk factors for stroke prospectively during a 6-year follow-up in the Turku Elderly Study, Turku, Finland. The study cohort consisted of 1032 people aged 70 years at baseline. The stroke events (ICD-9 codes 430-434) were identified by computer linkage from the hospital discharge and death registers, and from a follow-up questionnaire. During the 6 years of follow-up, 71 patients (6.9%) suffered a stroke. Previous stroke (RR 5.82), history of transient ischemic attack (RR 4.14), diabetes mellitus (RR 2.50), poorly controlled hypertension (RR 2.42), smoking (RR 1.94) and male sex (RR 1.65) were independent risk factors for stroke. Atrial fibrillation, cardiac failure and previous myocardial infarction did not appear to be significant independent predictors of stroke in the elderly. The risk of stroke in the elderly population appears to be strongly related to the concomitant clinical disease, and this should be remembered when identifying persons at increased risk of stroke. Poorly controlled hypertension was associated with an increased risk of stroke. Thus, achieving a good control of blood pressure in elderly hypertensives receiving treatment has the potential to prevent strokes.

The rapidly rising prevalence of obesity, worldwide, has prompted re-evaluations of the definitions and diagnostic criteria, and of the extent of the burden it contributes to health care services. Although categorized arbitrarily for epidemiological purposes according to BMI > 25 kg/m2 ('overweight') and BMI > 30 kg/m2 ('obese'), the disease itself (ICD code E.66) is the process of excess fat accumulation. It leads to multiple organ-specific pathological consequences, particularly if there is a tendency to intra-abdominal fat accumulation. The simplest field method to identify obesity and risk of medical problems is the waist circumference, and this method has found a special role in health promotion. Risks begin with waist > 80 cm (women) or > 94 cm (men). As a broad generalization, obesity produces few symptoms below the age of 40 years, but then several symptoms often develop; tiredness, breathlessness, back pain, arthritis, sweatiness, poor sleeping, depression and menstrual disorders all being common. The symptoms are often attributed to diseases in other body systems. Metabolic diseases like diabetes, hyperlipidaemia and, hypertension develop later, but the mean BMI at diagnosis of diabetes is 28 kg/m2. Ultimately, obesity increases the likelihood of myocardial infarction, stroke and several major cancers, but its biggest impact on health, especially in the elderly, is probably the multiplicity of effects on other body systems. The greatest challenge for public health is to develop effective preventive measures, recognizing that BMI > 25 kg/m2 before the age of 20 years is a very strong predictor of obesity and ill health in adulthood.

PURPOSE: The objective of this retrospective analysis was to compare secular changes in the rate of emergency room admissions (per 100,000) for selected acknowledged preventable cardiovascular conditions among African Americans (AA) men and women aged >/=21 from 1991-1998, and rate of change for Caucasian (Cau), Hispanic (Hisp), and Asian (Asi) men and women aged >/=21; conditions included angina, congestive heart failure (CHF), diabetes, and hypertension.METHODS: Results are derived from calendar-year California hospital data based on a selection of specified ICD-9 codes that correspond to the principal diagnosis for admission. The combined study sample size included a total of 21,016 individuals who were admitted to a hospital via the ER. Separate standardized and age-adjusted Poisson regression models were employed for each condition to assess race and time main effects and race x time interaction terms (P </= 0.01). Age and payer-source were entered as covariates to control for confounding effects. Men and women were analyzed separately.RESULTS: Mean overall rates of ER admission due to angina were significantly lower among AA men compared to Cau men (17.8 vs 18.2); however, rates were higher among Hisp and Asi men (6.03 and 7.1, respectively). Rates for CHF were higher among AA men compared to Cau, Hisp, and Asi men (23.7 vs, 11.0, 3.7, 4.8, respectively); similar results were observed for diabetes (8.6 vs 2.7, 2.3, 1.2, respectively) and hypertension (5.1 vs, 1.6, 0.9, 1.5, respectively). Differentials in 1991 resulted in widening disparities overtime for each condition. For women, mean overall rates due to angina were significantly higher among AA women compared Cau, Hisp, and Asi women (17.0 vs 13.5, 5.7, 5.7, respectively). Similar patterns were observed for CHF (23.1 vs, 11.0, 3.7, 4.8, respectively), diabetes (6.4 vs 2.0, 1.8, 1.1, respectively) and hypertension (5.8 vs 1.9, 1.1, 1.5), respectively). As observed among AA men, differentials in 1991 resulted in widening disparity overtime.CONCLUSIONS: Findings reveal higher rates of ER admissions for preventable cardiovascular conditions among AA men and women during the 1990s with evidence of widening health status disparities into the new millennium.

To assess maternal mortality in New York City, birth certificates and mortality records for New York City from 1988 through 1994 were linked and examined. During these 7 years, maternal mortality in New York City (defined by the International Classification of Diseases, 9th edition [ICD-9], as 630-676) per 100,000 live births significantly exceeded that of the country as a whole (20.2 vs. 8.2, respectively). Within New York City, an even greater variation of maternal mortality by race/ethnicity was noted, with the mortality ratio of whites, blacks, and Hispanics being 7.1, 39.5, and 14.4 per 100,000 live births, respectively. Socioeconomic characteristics such as educational attainment, marital status, and income influenced maternal mortality more in non-blacks than blacks. Analyses of cause-specific mortality revealed that, overall, ectopic pregnancy, embolism, and hypertension were the leading causes of death. However, the major factors explaining the excess maternal mortality among blacks were hypertension (mortality ratio of blacks to whites 5.57, 95% confidence interval 2.30-13.39), ectopic pregnancy (4.78, 95% confidence interval 2.40-9.51), and abortion (4.58, 95% confidence interval 1.72-12.22). These findings confirm a persisting gap in maternal death between black and white women. Indeed, if all New Yorkers who became pregnant enjoyed the survival of the city's non-Hispanic white residents, the difference in maternal mortality between the city and the nation would be eliminated.

This study evaluates the risk of mortality in a cohort of Italian alcoholics resident in a rural area characterised by traditional drinking habits. Individual vital status of the 1,037 patients enrolled at the Centro Alcologico in Arezzo during the 1979-1997 period has been traced. Causes of death (ICD-IX) have been retrieved from the Regional Mortality Register. Standardised mortality ratios (SMR) have been computed according to gender and 5-year age group mortality rates of the general population resident in Tuscany during the same period. This cohort is representative of the traditional rural alcoholism of the Tuscany region based on wine consumption. Among the 9,190 person-years followed-up, 333 deaths have occurred, corresponding to approximately 2.6 fold the expected number of deaths (SMR males: 2.6; females: 2.4). In both genders, significantly high SMRs for liver cirrhosis, oesophagus and liver cancer are reported, while SMRs of cancers at all sites, oral and respiratory cancers, injuries as a whole, road and traffic accidents, and suicides are significantly elevated only among males. No relevant variation between expected and observed deaths for pancreatic diseases, colon cancer, female breast cancer, and, despite a large proportion of heavy smokers, for cardiovascular diseases (hypertension, cerebrovascular diseases, coronary heart diseases) has been recorded. This research confirms the high mortality among a cohort of Italian alcoholics. However, causes of death related with violence and trauma are proportionally less represented, in accordance with the social pattern of Mediterranean alcoholism. The absence of cardiovascular mortality risk in a wine-based cohort of alcoholics is an unexpected finding that requires to be further examined. Finally, to prevent smoking related deaths, alcohol addiction services should begin to introduce smoking cessation practices among treatment protocols.

Based on the nationwide registration of the total hip arthroplasties (THAs) in Finland since 1980, a cohort of 24,638 patients with primary THA was gathered and followed for causes of death until December 31, 1996. The causes of death were divided into 20 main categories according to the classification of diseases ICD-10. The number of person-years was 153,410, and the mean length of follow-up of a person was 6.2 years. During the follow-up, 4,626 patients died; the expected number was 6,746. The standardized mortality ratio (SMR) was 0.69 (95% confidence interval; 0.67-0.70), without any difference between men and women. The total risk increased during the follow-up, with the highest being 0.84 (95% confidence interval, 0.81-0.87). Among the ICD categories, there were significantly low SMRs for cancers (0.54), accidents (0.74), cardiovascular diseases (0.70), and respiratory diseases (0.46). Among the diseases, there was a constant and significant decline of the SMR for dementia and Alzheimer's disease (0.50), diabetes (0.40), myocardial infarction (0.73), hypertension (0.68), other ischemic diseases (0.70), other heart diseases (0.57), and cerebrovascular diseases (0.70). The explanation for the decreased SMRs seems to be attributed to factors other than the THA per se, such as preoperative patient selection, more active lifestyle after THA, and possibly the use of anti-inflammatory drugs.

Citalopram is a chiral antidepressant drug. Its eutomer, S-citalopram (escitalopram), has recently been introduced as an antidepressant. In an open pilot study, four outpatients and two inpatients with a major depressive episode (ICD-10), and who were nonresponders to a 4-week pretreatment with 40-60 mg/day citalopram, were comedicated for another 4-week period with carbamazepine (200-400 mg/day). Some of the patients suffered also from comorbidities: Phobic anxiety disorder with panic attacks (n=2), generalised anxiety disorder, alcohol abuse, dependent personality disorder, hypertension (n=1). After a 4-week augmentation therapy with carbamazepine, a significant (P<0.03) decrease of the plasma concentrations of S-citalopram and R-citalopram, by 27 and 31%, respectively, was observed. Apparently, the probable induction of CYP3A4 by carbamazepine results in a nonstereoselective increase in N-demethylation of citalopram. Moreover, there was a significant (P<0.03) decrease of the ratio S/R-citalopram propionic acid derivative, the formation of it being partly regulated by MAO-A and MAO-B. Already, within 1 week after addition of carbamazepine, there was a slight but significant (P<0.03) decrease of the MADRS depression scores, from 27.0+/-7.7 (mean+/-S.D.) to 23.3+/-6.6, and the final score on day 56 was 18.8+/-10.9. The treatment was generally well tolerated. There was no evidence of occurrence of a serotonin syndrome. After augmentation with carbamazepine, treatment related adverse events were: Nausea in one case, diarrhea in one case, and rash in two cases. In conclusion, the results of this pilot study suggest that carbamazepine augmentation of a citalopram treatment in previous nonresponders to citalopram may be clinically useful, but that in addition carbamazepine can lead to a decrease of the plasma concentrations of the active enantiomer escitalopram.

Previous studies suggest that low bone mineral density (BMD) is associated with increased mortality, but the relationship between quantitative ultrasound (QUS) and mortality is unknown. We studied 5816 women over age 70 years enrolled in the Study of Osteoporotic Fractures. QUS of the calcaneus, and BMD of the calcaneus and hip, were measured at baseline, and women were contacted every 4 months to determine vital status. All reported deaths were confirmed by review of the death certificate or hospital records, and classified by ICD-9 code. During 5.0 years of follow-up, 677 women died. Women in the lowest quintile of QUS had the highest mortality during follow-up. After adjustment for age, grip strength, weight, height, health status, estrogen use, smoking, physical activity, and history of hypertension, diabetes, cardiovascular disease, cancer and stroke, each 1 SD reduction in broadband ultrasonic attenuation (BUA) was associated with a 16% increase in mortality (RH = 1.16; 95% CI: 1.07, 1.26). Mortality from cardiovascular disease, cancer and other causes were all increased among women with low QUS, but the association with cancer deaths was not statistically significant after multiple adjustments (RH = 1.09; CI: 0.93, 1.27). Low BMD was also associated with an increased risk of total and cause-specific mortality, but we found little evidence that BUA and BMD were independent predictors of mortality. Results were similar among women who did not fracture during follow-up. In this large population-based study of older women, low QUS is associated with both total and cause-specific mortality. This relationship was independent of other factors associated with mortality, such as age and health status, and suggests QUS and BMD may reflect some aspect of aging not captured by these traditional factors.
