The failed back or postlaminectomy syndrome is obviously multidimensional. Failure of therapy may result from structural abnormalities in the back, psychosocial influences, or a combination of both. The causes of back pain are largely unknown. ⋯ New additions to this category can be reduced by rigorous attention to physical abnormalities, so that surgery is undertaken only for clear indications, and appreciation of the importance of the psychologic aspects of disability from low back pain. The smaller group suffering principally from physical abnormalities can be improved by reparative surgery or pain-relieving procedures if intensive conservative rehabilitation efforts fail. All surgical procedures fail occasionally, and as long as there is a need for reparative surgery, some patients will fail to benefit or be worsened by the procedures.(ABSTRACT TRUNCATED AT 400 WORDS)

ReviewManagement of head injury. Treatment of abnormal intracranial pressure.
Intracranial hypertension is recognized as a fundamental pathophysiologic process in brain injury. Although the exact pressure level defining intracranial hypertension remains to be firmly established, the majority of evidence available currently suggests that ICP should generally be treated when it exceeds 20 mm Hg. We suggest that lesions in the temporal lobe be treated at 15 mm Hg owing to the special relationship of this region to the brain stem. ⋯ The basic mechanisms of raised ICP are slowly becoming elucidated. Clinical clues with which to subdivide patients with intracranial hypertension are being defined. New agents with efficacy in lowering raised ICP are appearing, and determination of their mechanisms of action may provide insight into the underlying disorder.

ReviewManagement of head injury. Intracranial pressure monitoring.
The role of intracranial pressure monitoring as an adjunct to the clinical examination, CT scanning, and other diagnostic modalities has become increasingly recognized. This article presents a brief overview of the present status of this technique and touches on prospects for further developments.

Gunshot wounds to the head are a common problem in the United States. A review of the literature and a survey of neurosurgeons suggests some differences of opinion regarding treatment. But the series upon which these opinions are based may be quite different. ⋯ Angiography should be used in cases in which bullets have passed near major vessels. We suggest an aggressive approach, with evacuation of clots and monitoring of intracranial pressure and treatment of elevations, as well as the routine use of anticonvulsants and antibiotics. Vocational rehabilitation is also important.
