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)
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)
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)
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)
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)
Nosocomial infections, which are not uncommon in neurosurgical intensive care medicine, may possibly be favoured by an impairment of immunological competence of the patient. In a prospective observational trial, we investigated several parameters of cellular and humoral immunity in 32 patients before and after resection of an intracranial tumour. 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 cystic process in the right frontal lobe of the brain in a man of 35 years of age, and an intramedullary cyst in the upper cervical spinal cord in a 29-year old woman, are described. In both cases, the wall of the cyst consisted of mucosal cells and cells having cilia pointing to the inside, located on a thin tissue layer, the structure of which resembled(More)
