Case ReportsManagement of intracerebral hemorrhage in idiopathic thrombocytopenic purpura. Report of four cases.
There has been little comment on the specific management of intracerebral bleeding occurring in patients suffering idiopathic thrombocytopenic purpura. The authors present the cases of four children with intracerebral hemorrhage due to this coagulation disturbance. ⋯ If necessary, the radiological investigation and surgical therapy can be performed with a single general anesthetic. Three of the patients have survived without major neurological sequelae.

Peripheral nerve stimulation in the treatment of intractable pain.
Peripheral nerve stimulating devices were implanted for pain control in 33 patients with a variety of disabling chronic pain conditions, which had persisted despite usual medical and surgical therapy. The implants were placed on major nerves innervating the area of the patient's pain. Records were obtained of each patient's stated relief from pain produced by nerve stimulation, along with assessments of narcotic withdrawal, ability to return to work, sleep pattern, and relief from depression. ⋯ The most dramatic successes occurred in patients with peripheral nerve trauma. The incidence of complications has been low, and two patients have used the stimulator for 5 years without adverse effects. Techniques of peripheral stimulator implantation, possible mechanisms of action, and conclusions regarding peripheral nerve stimulation in the treatment of chronic pain are discussed.

Microsurgery of Arnold-Chiari malformation in adults with and without hydromyelia.
Microsurgical exploration of 15 adults with Arnold-Chiari malformation with and without hydromyelia using 3 to 20 X magnification has led to the following conclusions. Hydromyelia, associated with Arnold-Chiari malformation, is a progressive mechanical disorder that causes spinal cord deficits by pressure distention of the cord. ⋯ If Pantopaque myelography in patients in the supine position shows the Arnold-Chiari malformation, hydromyelia can be established as a cause of central cord deficit even if myelography shows the cord size to be normal. Syringomyelia, traditionally considered a degenerative disease, is a less common cause of a slowly progressive central cord deficit than either hydromyelia or intramedullary tumor.

Effect of increasing the plasma oxygen diffusivity on experimental cryogenic edema.
Mongrel cats with experimental cryogenic brain lesions were treated with the carotenoid compound crocetin. It has been shown that crocetin increases the diffusion speed of oxygen through plasma, and should provide a net increase in available oxygen to the capillary endothelial cell. The treated group of animals showed a significant reduction in edema as compared to a comparable control group. It is suggested that oxygen availability is an important factor in vasogenic edema.

Case ReportsMoyamoya disease as a cause of subarachnoid hemorrhage in a Negro patient. Case report.
The authors describe a case of subarachnoid hemorrhage secondary to moyamoya disease in an adult Negro. To the authors' knowledge, this is the first such case reported. ⋯ The cause is unknown. Treatment consists of supportive care; the prognosis is variable.
