摘要:

CALCIUM PYROPHOSPHATE DEPOSITION disease is a relatively uncommon arthropathy characterized by the clinical features of pseudogout, the radiographic manifestations of chondrocalcinosis, and the pathological deposition of calcium pyrophosphate crystals in both hyaline and fibrocartilage. Symptomatic involvement of the spine by calcium pyrophosphate deposition disease is rare except by nodular deposition in the ligamentum flavum and atlanto-occipital ligament. We report a 50-year-old woman who presented with an acute herniated disc syndrome secondary to an intraspinal inflammatory calcium pyrophosphate deposition disease mass at the level of the L4-L5 interspace. The magnetic resonance image and histopathological features of the case are also discussed.

摘要:

THE SYMPTOMS OF a 62-year-old man with carpal tunnel syndrome resulting from poorly controlled gout subsided after the transverse carpal ligament was released surgically. At the time of the operation, the tophi were found to deposit on the median nerve rather than the transverse ligament, a situation reported only once before. The absence of gouty tenosynovitis in this patient was supported by the wound healing well without the chalky discharge that patients have had in previous reports.

摘要:

VENTRICULOPERITONEAL SHUNT MALFUNCTION is most commonly caused by obstruction of the ventricular catheter by choroid plexus. Such ventricular catheter obstructions remain a major unsolved problem, despite improvements in materials, catheter design, new valves, and increased emphasis on precise techniques favoring optimal catheter placement. Shunt malfunction demands elective and often urgent open surgical intervention to revise the shunt system. Such revisions require a general anesthetic in addition to the operative procedure and are followed by a minimum hospitalization of 2 to 3 days. Our experience with hundreds of shunt revisions prompted novel ideas for the development of a new ventricular catheter to treat or prevent this common and previously unresolved difficulty effectively.

摘要:

A SIMPLE TECHNIQUE for monitoring intracerebral temperature in humans via a ventricular catheter is described. This differs from a previously described method by enabling such measurements to be accomplished with a commercially available thermistor, a standard ventricular catheter, and common hospital supplies. In contrast to the earlier device, this system allows for the subcutaneous tunneling of the distal ventricular catheter. This is an easily assembled and cost-effective technique with which to conduct investigations on human intracerebral temperature.

摘要:

WE REPORT A case in which three-dimensional (3-D) magnetic source imaging, using the combined techniques of magnetoencephalography and 3-D magnetic resonance imaging, was employed to localize precisely a structural lesion in the precentral gyrus. The lesion was primarily a hematoma located in the right frontal lobe and was associated with a cryptic arteriovenous malformation that had produced repeated seizures with progressive left hemiparesis. 3-D magnetic source imaging mapped the entire somatosensory homunculus and localized the hematoma in the precentral gyrus. Both this relationship and the deduced localization were confirmed by a cortical recording of somatosensory evoked potentials at the time of surgery. 3-D magnetic source imaging proved to be useful in localizing cortical lesions precisely and in determining preoperatively the best form of treatment for the peri-Rolandic lesions.
