[Early rehabilitation of coma patients on the neurosurgical intensive care station. On the philosophy and practice of interdisciplinary cooperation].

The concept of early rehabilitation is an important task of humanity for neurosurgical intensive care patients emerging from coma. In Germany only little experience in this field has been reported, although the concept of early rehabilitation is well known in the other western European countries and the USA. In connection with the author's teaching activities at the pedagogical and psychological departments of the University of Oldenburg, an interdisciplinary concept of communicative "cooperative dialogues" was established for early rehabilitation, beginning in the earliest phases of coma at the neurosurgical intensive care unit. Although the results could not be evaluated statistically yet, the clinical course and outcome of emergence from primary or postoperative coma have improved rapidly by single patients, based on mobilization of neuronal plasticity and self-organized processes. Because of a significant lack of possibilities of early rehabilitation in the northwestern part of Germany, especially for young head injured adults, our efforts will continue. The philosophy and practice of early rehabilitation propose a new interpretation of neurosurgical patients emerging from coma, i.e. a dynamic process of a "second human creation". Early rehabilitation is an important task for the neurosurgically working doctor. Also for the neurosurgical profession the concept of early rehabilitation has to be integrated interdisciplinary to medical teaching at university level as soon as possible.

Practical co-table for direct coronal CT scanning.

Direct coronal CT scanning can be efficiently performed by a new co-table equipment, which requires a comfortable prone positioning of the patient, whereby the patient must only extend his head slightly. The co-table-unit is linked to the original CT table board directly within a few minutes, coming through the opening of the gantry from the rear. This practical co-table method serves to reduce motion artifacts and to improve image quality significantly. By this method coronal follow-up CT scans are exactly reproducable.

Nontraumatic intracerebellar hematomas: prognostic value of volumetric evaluation by computed tomography.

Thirty-two consecutive cases of nontraumatic intracerebellar hematomas detected by computed tomography are reviewed. A strong correlation was found between the clinical course and the volumetrically calculated size of the hematomas. Prompt evacuation has the best prognosis in cases that have an acute or subacute course (hematoma size, 22.5 to 66 cm3). Conservative treatment was most successful in chronic cases (hematoma size, 8 to 16 cm3). Surgical treatment should be the treatment of choice in very acute cases also (hematoma size, over 70 cm3) if the hematoma is diagnosed immediately after the onset of bleeding. Early detection and volumetric evaluation by computed tomography have great prognostic value for managing nontraumatic intracerebellar hematomas.

[On relapsing paraneoplastic cerebral embolism. Case report and survey of literature (author's transl)].

The disease of a 34-year-old patient with relapsing cerebral embolisms, endocarditis, thrombophlebitis and hypercoagulopathy had the characteristics of paraneoplastic syndromes described and discussed in literature. Autopsy yielded a clinically unrecognised, dedifferentiated adenocarcinoma of the bronchial system. At an early stage of the disease cerebral embolisms had produced severe cerebral neurological signs with varying manifestations. This influenced not only the clinical picture and course of the disease to a considerable extent, but also focussed diagnostic attention on these signs to such a degree that the possibility of a masked carcinoma did not seem to suggest itself. The assumption of paraneoplastic linkups is supported by experimental and postmortem examinations on metabolic and immunological remote action of tumours on cardiac valves and on the vascular and coagulation system. However, the exact pathogenetic details are still largely unknown.
