Review of the literature reveals that considerable knowledge has accumulated on intervertebral space infection following lumbar disc surgery. This is based on more than 400 observations. There are, however, no unifying concepts regarding the pathogenesis of the condition. While the reported incidence has seemed to increase in the last three decades, we(More)
Treatment of brain abscess is still a subject of controversy. Craniotomy with primary extirpation and resection of the abscess membrane, burrhole craniotomy with puncture or insertion of a drain, marsupialization, or stereotactic aspiration are different therapeutic approaches. As a consequence of our experiences and results with neuro-endoscopic(More)
A quarter of a century after the first description of a condition known as "normal pressure hydrocephalus", there no longer exists serious doubt about the existence of this disease nor about the possibility of treating it surgically with success. Nevertheless, there is still no general agreement on the exact definition of this condition, nor is there(More)
Nosocomial infection of the lower respiratory tract is a frequent and serious complication after major operations. A 32% incidence of lower respiratory tract infections was found after brain-tumor surgery in 289 patients, with a 21% incidence of pneumonia. In 186 of these patients (Group A), five factors were identified which were associated with an(More)
The body core temperatures of 31 patients suffering from severe cerebral lesions were measured. Evidence for the existence or nonexistence of circadian rhythms in these patients was found to be associated with diagnosis (acute versus chronic lesions), with the level of consciousness, and with neurological findings (such as best motor response and pupillary(More)
There is still a considerable controversy about the usefulness of antiepileptic prophylaxis after traumatic brain injury. Overall incidence of posttraumatic fits and epilepsy's is well known, but an individual decision on prophylaxis requires knowledge about the individual risk. We performed a prospective observational study on 612 patients with traumatic(More)
As far as medical decision making is based on weighing up individual risks and chances of a certain patient receiving a certain treatment, some knowledge is required about signs and symptoms which are associated with a certain outcome: they are called risk factors, or predictive factors. In lumbar intervertebral disc surgery, the most frequent undesired(More)
In three control groups of lumbar (L), cisternal (C), and ventricular (V) cerebrospinal fluid (CSF) with prealbumin contents of ventricular origin (CSF-V-prealbumin) within the reference range, indications for an increased transport of V-CSF into spinal space are presented in the elderly as well as an elevated production of V-CSF. Indications for a(More)
Starting in November, 1993, until January, 1994, we performed a survey among 127 Neurosurgical Departments in Austria, Germany, and Switzerland concerning the practice of antiepileptic prophylaxis in head injured patients. Seventy seven percent of the 12-item multiple choice questionnaires were completed and returned. They indicate a variety of attitudes(More)
Multiple CT investigations in critical ill neurosurgical patients are useful for monitoring the course of the illness and for the early detection of complications. CT's, however, are expensive and require transportation of the patient, which is often inconvenient and, in some cases, dangerous. The decision to perform CT scanning should be based on the(More)
