ReviewSpinal tuberculosis (Pott's disease): its clinical presentation, surgical management, and outcome. A survey study on 694 patients.
Tuberculosis (TB) of the spine (Pott's disease) is both the most common and most dangerous form of TB infection. Delay in establishing diagnosis and management cause spinal cord compression and spinal deformity. This study investigated the data on all cases of Pott's disease reported in Turkey from 1985 to 1996. ⋯ This meta-analysis demonstrates that in Turkey Pott's disease remains a serious problem, causing paraplegia. It should be considered when patients present with neurological findings suggesting spinal cord compression and spinal deformity. In the present study, it was concluded that the neurological involvement due to Pott's disease is relatively benign if urgent decompression is performed at the onset of the disease.

Randomized Controlled Trial Comparative Study Clinical TrialThe effects of intravenous fentanyl and lidocaine infiltration on the hemodynamic response to skull pin placement.
The aim of this study was to evaluate the effects of intravenous fentanyl and local lidocaine infiltration on the hemodynamic response to Mayfield skull pin head holder (MH) placement. Forty-five patients scheduled for elective craniotomy were studied. They were randomly divided into three groups. ⋯ In the L group, there was significantly higher MAP and HR during the placement of MH than in the FL group. In the FL group, there was no significant increase in MAP or HR at any time of the recordings. We conclude that intravenous fentanyl with local infiltration of lidocaine into the periosteum is effective in reducing the hemodynamic response to MH placement in patients undergoing craniotomy.

Meta Analysis Historical ArticleSpinal epidural abscess: a meta-analysis of 915 patients.
Spinal epidural abscess (SEA) was first described in the medical literature in 1761 and represents a severe, generally pyogenic infection of the epidural space requiring emergent neurosurgical intervention to avoid permanent neurologic deficits. Spinal epidural abscess comprises 0.2 to 2 cases per 10,000 hospital admissions. This review intends to offer detailed evaluation and a comprehensive meta-analysis of the international literature on SEA between 1954 and 1997, especially of patients who developed it following anesthetic procedures in the spinal canal. ⋯ The prognosis of patients who develop SEA following epidural anesthesia or analgesia is not better than that of patients with noniatrogenic SEA, and the mortality rate is also comparable. The essential problem of SEA lies in the necessity of early diagnosis, because only timely treatment is able to avoid or reduce permanent neurologic deficits. The problem with spinal epidural abscesses is not treatment, but early diagnosis - before massive neurological symptoms occur" (Strohecker and Grobovschek 1986).

Case ReportsBrain tissue pO2 related to SjvO2, ICP, and CPP in severe brain injury.
The aim of this report is to present first experience in comparing the course of brain tissue oxygen pressure values (PtiO2) to changes in jugular vein oxygen saturation (SjvO2), intracranial pressure (ICP), and cerebral perfusion pressure (CPP) after severe brain injury. PtiO2 monitoring was done using a polarographic Clark type microcatheter (LICOX pO2 probe) (GMS, Kiel, Germany) with a diameter of 0.5 mm and a sensitive area 7.9 mm long inserted in a right frontal position. The microcatheter was connected to a LICOX pO2 device. ⋯ Consistent correlations could be noticed between reduced PtiO2 and higher ICP and lower CPP levels. However, the absolute value of a single SjvO2 data point seemed to be less relevant diagnostically than its trend over a period of time. Owing to their experience, the authors suppose that PtiO2 monitoring will be a very important and reliable tool in the treatment of brain injury in the future, especially in its correlation to ICP and CPP.
