Randomized Controlled Trial Comparative Study Clinical TrialPostoperative pain after lumbar disc surgery: a comparison between parenteral ketorolac and narcotics.
Lumbar discectomy is a common elective surgical procedure but many patients still experience postoperative back pain which may delay hospital discharge. We therefore evaluated the efficacy of a parenteral non-steroidal antiinflammatory agent, ketorolac, for the management of post-surgical pain. ⋯ These results suggest that ketorolac, when used with PRN narcotics, is more effective than PRN narcotics alone for postoperative pain following lumbar disc surgery. In addition, this strategy also may contribute to early discharge from hospital after lumbar disc surgery.

ReviewNon-neoplastic cystic lesions of the sellar region presentation, diagnosis and management of eight cases and review of the literature.
The differential diagnosis of a sellar lesion includes pituitary adenoma, cranio-pharyngioma, tumour cyst, benign cyst, and other less common lesions such as aneurysm, squamous cell carcinoma and metastases. Pure cystic lesions within the sella turcica are not uncommon and may appear clinically and radiologically as pituitary adenoma. Intrasellar cysts are broadly classified as neoplastic or non-neoplastic; the latter may be primary lesions of the pituitary fossa or they may arise from the parasellar region and invade into the sella. ⋯ Investigations included computed tomography scan of the head for all and magnetic resonance imaging for six (75%) patients. Work-up included endocrinological and opthalmological evaluations. All presented with headache; six (75%) had visual acuity change, two (25%) had evidence of visual field defects, four (50%) had optic atrophy on fundoscopy, three (37.5%) had endocrine symptoms and hormone reduction was found in four (50%).

Randomized Controlled Trial Clinical TrialPostoperative pain therapy after lumbar disc surgery.
This study was undertaken to determine whether a special postoperative pain administration of tramadol and diclofenac provides any benefits in patients who underwent microsurgical lumbar discectomy. ⋯ The results suggest that the application of tramadol and diclofenac during the first 48 hours after lumbar microdiscectomy results in a reduction in postoperative pain without complications. We suggest that the use of this combination can be a beneficial adjunct to lumbar disc surgery.

Case ReportsCorrelation between jugular bulb oxygen saturation and partial pressure of brain tissue oxygen during CO2 and O2 reactivity tests in severely head-injured patients.
To correlate the jugular bulb oxygen saturation (SjvO2) and brain tissue oxygen pressure (PbtO2) during carbon dioxide (CO2) and oxygen (O2) reactivity tests in severely head-injured patients. ⋯ Correlation between SjvO2 and PbtO2 during CO2 reactivity test is low, even if significant differences between normo- and hyperventilation values are present. In comparison to SjvO2, monitoring of PbtO2 might more accurately detect possible focal ischaemic events during rapidly induced hyperventilation in severely head-injured patients. The CO2 vasoreactivity by means of changes in Vm MCA seems to be higher in comparison to changes of PbtO2. These observations lead to the hypothesis that vasoreactivity measured by TCD overestimates the cerebrovascular response to CO2.

Brain death and organ donation in Germany: analysis of procurement in a neurosurgical unit and review of press reports.
A prospective study was undertaken to determine the number of potential organ donors in a neurosurgical intensive care unit and to record the actual number of organ donations. The reasons for refusal of organ donations were analysed with respect to the controversial public discussion of the brain death concept and the transplantation law in Germany. ⋯ In Germany, the relatives refusal rate in organ donation is continuously high, presumable due to a depressing 39% of press reports rejecting the brain death concept, and resulting in a very low number of organ donations. There is hope that the transplantation law which has finally passed German parliament in 1997, confirming the brain death concept as well as the legal principle of prior consent by the donor or consent by the relatives will eventually result in an increase of organ donation especially when supported by an educational campaign which is embodied in the transplantation law.
