The SF-36 Health Survey and its 12-item abridged form is an instrument for the assessment of health related quality of life that can be used with healthy persons and patient populations. Its use has been recommended within a large German multicentre rehabilitation research programme. The paper examines missing data across all five study projects of the North German Network for Rehabilitation Research (NVRF) as well as psychometric properties of the instrument.

Health-related quality of life is a key element of successful aging. With life expectancy increasing, postmenopausal estrogen/gestagen replacement therapy has been under discussion for some time with the aim of achieving a higher quality of life in old age. For a long time, the relevance of hormonal aging was only discussed with reference to women; however, more recent work deals with concepts that affect both sexes.

Objectives: The 34Leu polymorphism of the factor XIII gene is associated with a low rate of brain infarction and a higher incidence of primary intracerebral hemorrhage in adults. We evaluated the effect of the polymorphism on the subsequent development of isolated intracranial hemorrhage and white matter disease in preterm infants with a birth weight <1500 g (very low birth weight [VLBW] infants).

Study Design: We studied 531 VLBW infants and 301 control infants born at term.

By application of a standardized core set of outcome measurement instruments, comparison between studies as well as meta-analyses in rehabilitation research can be facilitated. The German Society for Rheumatology has commissioned its working group on rehabilitation with the development of a proposal for such a core set of outcome measurement instruments. In a first step, dimensions for outcome measurement in rehabilitation were defined by a group of experts which represented rehabilitation hospitals, acute care hospitals, and research groups specialized in outcome measurement.

Unlabelled: The influence of genetic factors that increase coagulation on the extension of intraventricular haemorrhage (IVH) in very low birthweight infants has not been studied previously. This study investigated the frequency and effect of the factor V Leiden and prothrombin G20210A mutations in a population-based cohort of 305 preterm infants with a birthweight below 1500 g. The overall prevalence of IVH was similar in infants with (n = 43) and without (n = 262) prothrombotic mutations (18.

The factor-V-Leiden mutation is seen in high frequencies in white people, despite its contribution to second-trimester abortion, preterm birth, and deep-vein thrombosis. The reason for its high frequency is not known. We investigated 102 mother-child pairs who had had successful in-vitro fertilisation by intracytoplasmic sperm injection as a model for human implantation.

Against the background of current and future demographic changes the relevance of medical rehabilitation in the German health care system is generally acknowledged. It is a central element of treatment programmes especially for elderly and chronically ill patients. In recent years, problems due to lack of co-operation and communication as well as insufficient links between acute care and rehabilitation treatment have found increasing attention.

There is an ongoing controversy concerning the use of bone density measurements within therapeutic and preventive strategies of osteoporosis. Since there are no randomized controlled trials evaluating the effectiveness of bone density measurement with subsequent therapy we used a "critical pathway" model to determine possible benefit of tertiary, secondary and primary preventive strategies utilizing bone density measurement. In a first step data for fracture risk in each group are extracted from the literature.

Background: Abnormalities in cardiac function, eg, arrhythmias and congestive heart failure, often accompany thyrotoxicosis. A relationship between thyroid hormone excess and the cardiac complications of angina pectoris and myocardial infarction (MI) remains largely speculative.

Methods: The results of thyroid function studies on blood samples drawn from a total of 1049 patients (aged 40 years or older) immediately on emergency medical admission were related to frequencies of angina pectoris and myocardial infarction as determined according to current diagnostic algorithms.

Backschools are utilized for primary, secondary and tertiary prevention of nonspecific low back pain while there is considerable doubt concerning their effectiveness. We present the results of controlled clinical trials that examine the effectiveness of back schools as reported in recent systematic reviews of the literature. An extensive literature search for systematic reviews summarizing the results of controlled trials was performed.

Several studies have shown that growth hormone deficiency in adults leads to poor well-being and other clinical consequences, and that these improve when the hormone is replaced. However, the studies employed generic measures of health status that miss important aspects of the patients' experience and that have inadequate reliability and responsiveness. This paper describes the European development and testing of the Quality of Life-Assessment of Growth Hormone Deficiency in Adults (QoL-AGHDA), a condition-specific quality of life measure for use in clinical trials and for the routine monitoring of patients.

The evaluation of medical technologies, Health Technology Assessment (HTA), is gaining more and more importance in Germany. Starting from a comprehensive definition of the term medical technology, this article first describes the development of HTA since the seventies as an instrument for improving decision-making in health policy. HTA is presented as a repetitive cycle of a sequence of steps starting with the prioritization of topics to be evaluated to the analysis of the impact of the results.

This paper describes the international development and psychometric testing of the Recurrent Genital Herpes Quality of Life Questionnaire (RGHQoL), a condition-specific quality of life (QoL) instrument. The theoretical foundation for the measure is the needs-based model of QoL and the content of the instrument was derived from in-depth qualitative interviews with relevant patients in the UK. Versions of the RGHQoL were required for the UK, USA, Italy, Germany, France and Denmark for use in international clinical trials.

Ketones can reactivate the production of fetal hemoglobin (HbF) in vitro and in vivo. A reactivation of HbF by ketones, which are generated during starvation, remains largely speculative. Therefore, we investigated HbF in 31 women with anorexia nervosa or bulimia, using both of these as models of intermittent starvation ketosis.
