OBJECTIVE The objective of our study was to field test different chronic migraine (CM) criteria and compare CM epidemiological profiles, which include demographic, personal, and lifestyle characteristics, with high-frequency episodic migraine (HFEM) and low-frequency episodic migraine (LFEM). METHODS Questionnaires were mailed to a random sample of 18,000(More)
We report on two patients in whom the anomalous left main coronary artery arising from the right sinus of Valsalva with a septal course could be visualized by transthoracic echocardiography. It appeared as a small echo-free space, anterior to the aorta in the short parasternal axis. If the left main coronary artery arises anomalously from the right sinus of(More)
The effect of tyramine infusion or exercise on catecholamine concentration and dopamine-β-hydroxylase activity in plasma of normal volunteers has been studied. Whereas the increase in plasma catecholamine concentrations by tyramine infusion was not changed 90 min after oral application of a single dose ofβ-adrenoceptor blocking drugs (penbutolol, practolol,(More)

The objective of this study was to determine the reproducibility of ultrasonic bone properties with a system for measuring calcanei ex situ; the influence of changes of the measurement site; and the effects of fixation, storage, and maceration. We examined 14 fixed calcanei and 12 fresh bones. Ultrasonic measurements were performed ex situ after degassing,(More)
Out of 144 patients with kyphotic deformities in Ankylosing spondylitis 33 (23%) had 45 disco-vertebral lesions of the spondylodiscitic type. They were characterized by osteolyses, scleroses and absence of syndesmophytes. 5 had additional arch fractures. All were localized in or below the apical vertebra in the lumber or the lower thoracic spine. Compared(More)
The dose-effect relation and duration of action of 2 mg, 4 mg and 6 mg molsidomine on ischemic ST-segment depression in the exercise-ECG were determined in a randomized and double-blind acute study of 12 patients with confirmed coronary artery disease. With 2 mg molsidomine a significant reduction in the amount of ischemic ST-depression from 18.0 mm to 8.1(More)
The clinical-chronopharmacological investigations with oral nitrates (ISDN, IS-5-MN) demonstrate that the drugs' pharmacokinetics and/or hemodynamic effects are circadian phase-dependent. For both an immediate-release and a sustained-release preparation of IS-5-MN peak drug concentrations coincided with peak drug effects after morning but not after evening(More)
In the surgical treatment of craniosynostosis and craniofacial dysostosis in the growing child, passive intraosseous translocation (PIT effect) with intracranial displacement of metal plates and screws may be a problem. In an animal experiment, a possible PIT effect using resorbable PLA/PGA miniplates (Lactosorb, W. Lorenz, FL, USA) following(More)
This systematic review summarises the literature on patient selection, decision-making, effectiveness and outcomes in the surgical treatment of lumbar degenerative spondylolisthesis (LDS). In daily practice, decision-making in the treatment of LDS is challenging. There is little consensus on either the precise indications or prognostic factors for any(More)
