A double-blind, randomized, parallel, comparative study was designed to evaluate the long-term safety and efficacy of subgingivally administered minocycline ointment versus a vehicle control.
One hundred four patients (104) with moderate to severe adult periodontitis (34 to 64 years of age; mean 46 years) were enrolled in the study. Following scaling and root planing, patients were randomized to receive either 2% minocycline ointment or a matched vehicle control. Study medication was administered directly into the periodontal pocket with a specially designed, graduated, disposable applicator at baseline; week 2; and at months 1, 3, 6, 9, and 12. Scaling and root planing was repeated at months 6 and 12. Standard clinical variables (including probing depth and attachment level) were evaluated at baseline and at months 1, 3, 6, 9, 12, and 15. Microbiological sampling using DNA probes was done at baseline; at week 2; and at months 1, 3, 6, 9, 12, and 15.
Both treatment groups showed significant and clinically relevant reductions in the numbers of each of the 7 microorganisms measured during the entire 15-month study period. When differences were detected, sites treated with minocycline ointment always produced statistically significantly greater reductions than sites which received the vehicle control. For initial pockets > or =5 mm, a mean reduction in probing depth of 1.9 mm was seen in the test sites, versus 1.2 mm in the control sites. Sites with a baseline probing depth > or =7 mm and bleeding index >2 showed an average of 2.5 mm reduction with minocycline versus 1.5 mm with the vehicle. Gains in attachment (0.9 mm and 1.1 mm) were observed in minocycline-treated sites, with baseline probing depth > or =5 mm and > or =7 mm, respectively, compared with 0.5 mm and 0.7 mm gain at control sites. Subgingival administration of minocycline ointment was well tolerated.
Overall, the results demonstrate that repeated subgingival administration of minocycline ointment in the treatment of adult periodontitis is safe and leads to significant adjunctive improvement after subgingival instrumentation in both clinical and microbiologic variables over a 15-month period.
In the last several years, West Nile virus (WNV) was proven to be present especially in the neighboring countries of Austria, such as Italy, Hungary, and the Czech Republic, as well as in eastern parts of Austria, where it was detected in migratory and domestic birds. In summer 2010, infections with WNV were reported from Romania and northern Greece with about 150 diseased and increasingly fatal cases. We tested the sera of 1,607 blood donors from North Tyrol (Austria) and South Tyrol (Italy) for antibodies against WNV by using IgG enzyme-linked immunosorbent assay (ELISA). Initial results of the ELISA tests showed seroprevalence rates of 46.2% in North Tyrol and 0.5% in South Tyrol, which turned out to be false-positive cross-reactions with antibodies against tick-borne encephalitis virus (TBEV) by adjacent neutralization assays. These results indicate that seropositivity against WNV requires confirmation by neutralization assays, as cross-reactivity with TBEV is frequent and because, currently, WNV is not endemic in the study area.
OBJECTIVE: To investigate determinants of the acceptability of isoflavone products among postmenopausal women with regard to social and lifestyle factors, dietary habits, health concerns, food beliefs, menopausal symptoms and therapies, and to elucidate preferences for specific products. METHODS: A consumer survey was conducted among postmenopausal women in four European countries (Germany, Denmark, Italy and the UK), including a total of 465 respondents. RESULTS: The declared acceptability of isoflavones was highest in Germany (80%), followed by Italy (75%), the UK (59%) and Denmark (55%; p
As the development in mean age of the population and life expectancy has been less favourable in Denmark than in the rest of Western Europe, the Ministry of Health decided to investigate statistics for the period, 1972-1990, for the main areas where Danish life expectancy was poorer. A sharp increase in the incidence of accidental poisoning with medical drugs and alcohol during the period was found to be a factor contributing to the poorer Danish statistics during the period. In the subcategory, death after a fall, there was an increase in incidence among the elderly, but the loss of life-years remained constant. The subcategory, fatal road accidents, manifested a marked reduction in incidence, despite the increase in traffic density during the period, and there was a reduction in the loss of life-years. Thus, in the category, accidental deaths, the increase in the incidence of accidental poisonings would appear to be the only factor contributing to the poorer development in mean age and life expectancy in Denmark.
Little is known about whether the accuracy of tools for assessment of sexual offender recidivism risk holds across ethnic minority offenders. I investigated the predictive validity across ethnicity for the RRASOR and the Static-99 actuarial risk assessment procedures in a national cohort of all adult male sex offenders released from prison in Sweden 1993-1997. Subjects ordered out of Sweden upon release from prison were excluded and remaining subjects (N = 1303) divided into three subgroups based on citizenship. Eighty-three percent of the subjects were of Nordic ethnicity, and non-Nordic citizens were either of non-Nordic European (n = 49, hereafter called European) or African Asian descent (n = 128). The two tools were equally accurate among Nordic and European sexual offenders for the prediction of any sexual and any violent nonsexual recidivism. In contrast, neither measure could differentiate African Asian sexual or violent recidivists from nonrecidivists. Compared to European offenders, AfricanAsian offenders had more often sexually victimized a nonrelative or stranger, had higher Static-99 scores, were younger, more often single, and more often homeless. The results require replication, but suggest that the promising predictive validity seen with some risk assessment tools may not generalize across offender ethnicity or migration status. More speculatively, different risk factors or causal chains might be involved in the development or persistence of offending among minority or immigrant sexual abusers.
Repeated epidemiologic study of atherosclerosis in males on the basis of autopsy material with 25-year interval (1963-66 and 1985-89) has been performed in 7 European cities (Malmö, Praha, Riga, Tallinn, Tartu, Kharkov, Yalta) and 4 Asia cities (Ashkhabad, Bishkek, Irkutsk, Yakutsk). Accelerated development of atherosclerosis in the 2nd study has been revealed in males in the majority of cities except Malmö and Praha. No significant differences in atherosclerosis of aorta and coronary arteries were found in these two cities. An increase of the calcinosis surface in the coronary arteries combined with a higher incidence of coronary stenosis was typical for the 2nd study. Atherosclerosis was less pronounced in the indigenous population of Ashkhabad, Bishkek and Yakutsk in both studied than in non-indigenous populations. There was a positive correlation in males between lethality of coronary heart disease and other cardiovascular diseases and the degree of coronary atherosclerosis. Thus, the course of atherosclerosis can change within the life of one generation.
This article summarizes the most important results of the Turku Conference on active strategies for an aging workforce, which took place in Turku/Finland in 1999. About 140 experts from all EU-member states participated. The article can be seen as a contribution to the current change in the debate on labor market policy concerning older workers in Germany.
