[Legal definition of the accident concept in social accident insurance].
For the first time, the "Gesetz zur Einordnung des Rechts der gesetzlichen Unfallversicherung in das Sozialgesetzbuch (Unfallversicherungs-Einordnungsgesetz UVEG)" from August 7, 1996, defines the term "accident" in the social accident insurance, as expressed since January 1, 1997, in 8 I Sozialgesetzbuch (SGB) VII. This legal definition widely corresponds to the definition in the private accident insurance as well as to the previous interpretation known from the literature and the jurisdiction.

Comparative StudyTranscranial duplex-sonography in intracranial hemorrhage. Evaluation of transcranial duplex-sonography in the diagnosis of spontaneous and traumatic intracranial hemorrhage.
The aim of this prospective clinical study was to evaluate the potential of bedside transcranial color-coded duplex sonography (TDS) in the assessment of patients with acute intracranial hemorrhage and respective complications. 74 patients (35 with spontaneous and 27 with traumatic hemorrhage, 12 excluded due to insufficient insonability) underwent 152 TDS examinations. The results were compared to computer-tomography (CT) as well as conventional transcranial Doppler sonography (TcD). ⋯ The TDS findings for the diameter of third and lateral ventricles (n = 126) as for midline-shift (n = 26) showed a good correlation (p < 0.0005) to CT-measurements. TDS appears to be a useful bedside, non-invasive tool in order to detect and exclude intracranial complications in patients with intracranial hemorrhages.

Vasomotion, regional cerebral blood flow and intracranial pressure after induced subarachnoid haemorrhage in rats.
The objective of our study was to examine the relation of the intracranial pressure (ICP), cerebral perfusion pressure (CPP), regional cerebral blood flow (rCBF), and vasomotion in the acute phase in rats after having induced subarachnoid haemorrhage (SAH). The experiments were carried out on a total of 21 Wistar rats by means of neuroleptanalgesia and controlled mechanical ventilation. In 16 animals SAH was induced according to the method described by Solomon et al. with a fractionated application of 0.5 ml autologous blood into the cisterna magna. ⋯ After having induced SAH an impairment of the cerebral autoregulation becomes apparent which seems to manifest itself on the level of microvascular structures as a suppressed behaviour pattern of vasomotion. Although basal vessels may constrict distal parenchymal vessels tend to dilate after SAH. The dilation-described as a reduction of vasomotion-could also be measured in clinical situations by means of laserdoppler fluxmetry.

[Insurance law aspects in expert assessment of isolated traumatic intervertebral disk displacements].
The present paper illustrates the insurance-law aspects of isolated traumatic disc herniation in Germany. The significance of the different terms of insurance in both the personal and the social accident insurance for medical expert opinion is elucidated.
