ReviewFollow-up computerized tomography (CT) scans in moderate and severe head injuries: correlation with Glasgow Coma Scores (GCS), and complication rate.
The wide availability of computerized tomography (CT) scan has popularized its use in initial and follow-up evaluations of head trauma patients. Follow-up CT scans of clinically stable patients, however, may not provide additional information, but could potentially subject the patients to secondary injuries. The authors investigated the correlation between CT scans and Glasgow coma score (GCS), and complication rate during follow-up CT scans in an attempt to dissuade clinicians from obtaining unnecessary follow-up CT scans. ⋯ Because of the correlation between the CT scan appearance and the clinical status, as well as the detrimental effect of mobilizing critically ill patients, the authors urge the use of follow-up CT scans only in patients with clinical deterioration unexplained by ICP changes alone.

ReviewPrognostic factors in severely head injured adult patients with acute subdural haematoma's.
A medline search back to 1975 was undertaken to identify relevant papers published on subdural haematomas. The search was restricted, whenever possible, to adult age and comatose patients. Forty relevant reports were identified. ⋯ In terms of prognosis, the following parameters were found to be significant: age, time from injury to treatment, presence of pupillary abnormalities, GCS/motor score on admission, immediate coma or lucid interval, CT findings (haematoma volume, degree of midline shift, associated intradural lesion, compression of basal cisterns), post-operative ICP and the type of surgery. Improving the outcome of patients with acute subdural haematoma's is a difficult task. A small subpopulation of patients may have a benign course without surgical haematoma evacuation, but all comatose patients with an acute subdural haematoma should be treated in Centers where neurosurgical facilities and appropriate monitoring are available.

Comparative StudyComparison of serial S-100 and NSE serum measurements after severe head injury.
We investigated the time course of neuron specific enolase (NSE) and S-100 protein after severe head injury in correlation to outcome. We included 30 patients (GCS < 9), who had been admitted within 5 hours after injury, in a prospective study. Blood samples were taken on admission, 6, 12, and 24 hours and every 24 hours up to the fifth day after injury. ⋯ Four patients with increasing intracranial pressure showed a quick increasing concentration of NSE, in two patients the S-100 level showed a slower rise. The NSE serum levels did not correlate with intracranial pressure values. Our results show that the first serum concentration of S-100 seems to be predictive for outcome after severe head injury.

Case ReportsPermanent postoperative anosmia: a hitherto undescribed complication following surgery of the posterior cranial fossa in the sitting position.
Although the sitting position offers advantages for posterior fossa surgery, it is accompanied by complications such as air embolism and pneumatocephalus. Subdural and epidural haematomas are less common postoperative complications of posterior fossa surgery. To the best of our knowledge, however, anosmia is not a known sequela of surgery in the sitting position. It has been described following aneurysm surgery in the rostral part of the circle of Willis and is, of course, well known in traumatic brain injury.

Comparative StudyPeriradicular therapy in lumbar radicular syndromes: methodology and results.
Periradicular therapy (PRT) has become popular in the treatment of lumbar radicular complaints, both primary, due to disc herniations (Group 1), and postoperative, following disc surgery (Group 2). However, hitherto reported data on 'periradicular injections' are more of a technical nature. The present study was designed to evaluate the therapeutic success of CT- versus fluoroscope-guided periradicular injections of local anaesthetics and corticoids, and to investigate the impact of imaging procedures on the results. ⋯ Long-term follow-up shows that there is no positive effect in those patients in whom the first two PRT attempts had failed. Thus, PRT represents a useful long-term therapeutic alternative for lumbar radicular syndromes, particularly when due to primary discogenic compression. CT-guided injection is superior to fluoroscope-assisted treatment for both its visualization and its longer-lasting effect.
