A second Dutch National Survey of General Practice was carried out in 2001 with the aim of providing actual information about the role of general practice in the Dutch health-care system for researchers and policy makers. Data were collected on different levels (patients, general practitioners, practices) and included morbidity (self-report and presented to general practitioners), diagnostic and therapeutic interventions, doctor-patient communication, and background characteristics. Compared to 1987 (the first National Survey), Dutch general practitioners had organized their work more efficiently. ⋯ Dutch general practitioners provide high-quality care: on average, their performance was in 74% of cases in accordance with national guidelines. Communication in general practice had become less social and more medically oriented compared to 1987. General practice still acts in a gatekeeper role; this is illustrated by 96% of contacts handled solely by the general practitioner.

Within the last years, health services research has gained increasing attention in Germany. This trend could also be observed in dentistry although this research field must be considered rather young. The methodical approach of health services research is complementary to the traditional clinical research paradigm. The latter focuses on the comprehension of causal mechanisms and the efficacy of interventions under ideal and standardized study conditions. In contrast to that, health services research focuses on the effectiveness under everyday conditions and the efficacy in the normal course of medical care. ⋯ Hence it can be said that dental health services research in Germany is not sufficiently established yet. It can be assumed that the cumulating problems to be expected within the health care system will lead to an increasing demand for the respective research.

This review may serve as a basis for evaluating publications on the topic "myocardial biopsy for myocarditis and dilated cardiomyopathy" in the clinical practice. The literature is particularly analyzed to answer the question, whether an endomyocardial catheter biopsy is indicated in patients with these myocardial disorders in the clinical routine besides its unequivocal scientific value. The judgment of the biopsy samples has been based on the classically histological and for years on the additional immunohistochemical and molecular biological-virological examination. ⋯ It is missleading to replace the well-established clinical diagnosis myocarditis by the bioptic diagnosis "inflammatory cardiomyopathy". However, endomyocardial catheter biopsy is clearly indicated in rare patients with fulminant myocarditis, giant-cell myocarditis and myocardial storage disease. Its probably underestimated role in sarcoid heart disease still needs to be clarified by systematic studies.

Differential diagnosis of acute tetraparesis includes paraplegia caused by trauma, ischemia, inflammation or tumor, Guillain-Barré syndrome, periodic paralysis, myasthenia gravis, and dissociative paralysis. ⋯ Hypokalemic thyrotoxic periodic paralysis (HTPP), a subtype of hypokalemic paralysis, is unusual in Caucasians. In Asian men the disease is more common. The underlying mechanism is an extra-intracellular shift of potassium in the voluntary muscle cells. In contrast to hereditary autosomal dominant paralyses, a genetic defect is not known. Usually, symptoms of hyperthyreosis in HTPP are mild which can hamper the correct diagnosis.

Patient safety is the latest issue in the present stage of the German health care system, characterized by costs and quality both resulting in value of care. Patient safety defined as "absence of adverse events" represents an important problem, because 10% of in-house patients experience an adverse event, which in nearly 50% of the cases is due to an error (preventable adverse event). Threats and near misses are errors without a consecutive adverse event, much more common and better to integrate in the concept of risk management, which is based on thorough analysis and prevention of errors in medicine. ⋯ The medical and other professions, on the other side, have to change their self-understanding from the zero mistake philosophy to accepting errors as common events. This understanding is a prerequisite that analysis can be performed. The participation of patients should be strengthened, because public disclosure is an important issue, although the scientific evidence for real improvement in health care resulting from public disclosure is still inconclusive.
