[Prevalence and incidence of dementia in Germany--a study based on data from the public sick funds in 2002]. / Prävalenz und Inzidenz von Demenz in Deutschland--Eine Studie auf Basis von Daten der gesetzlichen Krankenversicherungen von 2002.

So far all calculations of the number of demented people are based on rates from meta-analyses, mean rates of meta-analyses or spatial analyses. This article presents age- and gender-specific prevalence and incidence rates of dementia that are based on a large sample of the German Sick Funds (Stichprobendaten von Versicherten der gesetzlichen Krankenversicherung (GKV)) with 2.3 million people from the year 2002. Prevalence rates increase from 0.8% and 0.6% for 60-64 year old men and women to 30% and 43% for men and women aged 100 or older, respectively. Incidence rates increase from 0.18 and 0.14 cases per 100 person-years for 60-64-year old men and women to 9.9 and 10.9 for over 95 year old men and women, respectively. Our results confirm rates from earlier studies on the basis of meta-analyses. Regional differences show for the first time that higher prevalence rates exist for East German women and men above age 85. In 2007 about 1.07 million moderately or severely demented people live in Germany of which about 244 000 are incident cases when we extrapolate our rates to the population of this year.

[Results of multidisciplinary assessment of patients with erectile dysfunction]. / Ergebnisse nach multidisziplinärer Abklärung bei Patienten mit erektiler Dysfunktion.

A total of 326 patients with chronic erectile dysfunction were investigated by a multidisciplinary approach. It was found that several causes combined (multifactorial genesis) in 77.1%. Organic causes alone were found quite frequently, viz. in 43.6%, while primarily psychogenic causes alone were found in only 5.5%; in contrast, combined organic and psychogenic causes were found in 46.0%. There were pathologic organic findings in 89.6%: vascular in 74.5% (arterial 64.1%, cavernous/venous 30.4%), neurogenic in 42.0%; side effects of drugs in (10.1%); endocrine (7.7%) and local penile causes (4.3%) are not so important in erectile dysfunction. Treatment suited to the pathogenesis was instituted (psychotherapy, vein ligation, self-injection of vasoactive drugs into the corpus cavernosum).
