Impact of traumatic subarachnoid hemorrhage on outcome in nonpenetrating head injury. Part I: A proposed computerized tomography grading scale.
The presence of traumatic subarachnoid hemorrhage (tSAH) on admission computerized tomography (CT) scans obtained from patients suffering from severe, nonpenetrating head injury has been shown to be associated with a worse outcome than the injury alone would warrant. However, no previous study has provided a simple means of relating the amount of tSAH, its location, or other abnormal findings on initial head CT scans to outcome in patients with non-penetrating head injury. In this study, admission head CT scans from 252 patients with tSAH, treated at a single institution, were reviewed to ascertain thickness of the tSAH; its location; evidence of mass lesion(s); shift of midline structures (< or = 5 mm vs. > 5 mm); basal cistern effacement; and cortical sulcal effacement. ⋯ Further analysis comparing CT grades and admission postresuscitation Glasgow Coma Scale (GCS) scores was highly significant. Patients with lower CT grades had better admission GCS values and discharge GOS scores than those with higher CT grades. From their experience, the authors conclude that their CT grading scale is simple and reliable and relates significantly to outcome at the time of discharge from acute hospitalization.

En bloc petrosectomy using a Gigli saw for petroclival lesions. Technical note.
The authors report a new technique for en bloc petrosectomy using a Gigli saw as an alternative to drilling the petrous bone in the combined supra- and infratentorial approach or the transpetrosal-transtentorial approach. It is simple and easy and avoids postoperative cosmetic deformity. This technique has been performed in 11 petroclival lesions without injuring the semicircular canals, the cochlea, or the facial nerve.

Case ReportsSpontaneous carotid-jugular fistula and carotid dissection in a patient with multiple intracranial arachnoid cysts and hemifacial atrophy: a generalized connective tissue disorder? Case report.
The authors report a case of a 45-year-old woman with pulsatile tinnitus who was found to have an unusual spontaneous fistula between the petrous internal carotid artery and internal jugular vein. The fistula resolved spontaneously, possibly related to daily manual compression of the ipsilateral common carotid artery. ⋯ Her medical history was significant for easy bruisibility, abnormal scarring, and mitral valve prolapse. This association appears unique and may represent a previously underscribed generalized connective tissue disorder.

A prospective study of intrathecal catheter reliability was performed at Rush-Presbyterian-St. Luke's Medical Center. All 102 patients who had baclofen administered chronically for spasticity via an implanted drug pump were included. ⋯ Survival analysis demonstrated a steady rate of malfunction up to 80 months, with the mean time to first failure recorded at 20 months. Kinks, holes, breaks, dislodgments, and disconnections were the most common complications. On the basis of their research the authors conclude that the thin-walled silastic catheter does not perform well and that larger, thick-walled catheters should be used.

Review Case ReportsParadoxical progression of tuberculous lesions during chemotherapy of central nervous system tuberculosis. Report of four cases.
The peculiar phenomenon of paradoxical progression during the treatment of central nervous system tuberculosis is discussed. A few cases with this phenomenon were reported in the past, and the authors have treated four such cases. ⋯ All four patients underwent ventriculoperitoneal shunt insertion during the course of treatment. The authors discuss the significance of the changes in the lesions and management of such cases, and review the literature.
