Comprehensive stroke care: an overview.

Stroke is a global epidemic and an important cause of morbidity and mortality. It ranks next to cardiovascular disease and cancer as a cause of death. "India is likely to suffer huge social and economic burden in the rehabilitation of stroke patients owing to increased life expectancy" and urbanization. Though, there are national programs in malaria eradication and tuberculosis control, there is hardly any governmental support in stroke management and rehabilitation. We propose to formulate stroke-prevention strategies specific to our national needs and covering all the age groups. Allocation of resources towards the stroke management and research is needed. Emphasis on stroke awareness in community should be stressed and should be inclusive of means of primordial and primary prevention apart from management of stroke and its recurrence. Recent international experience in stroke management has suggested the need of specialized stroke units (comprehensive stroke care under one roof). We wish to establish the need of creating awareness regarding the urgency of specialized care in acute stroke. We also wish to motivate our national health institutions to offer affordable, evidence based management of stroke and offer opportunities in stroke training and research.

Abulia: no will, no way.

Abulia refers to impaired ability to perform voluntary actions, show initiative, make decisions along with decrease in movements, speech, thought and emotional reactions. We describe here two patients who developed this condition following bilateral insult to different sites in the centromedial core of the brain, the first following the cerebral venous thrombosis and the second after the right ACA and MCA infarct. Both these patients improved following treatment with Bromocriptine. These cases are described for proper identification and management by the clinicians.

Treatment of memory impairment, vertigo and tinnitus in the elderly with piribedil in an Indian general practice setting.

Age-related dopamine decline leads to memory impairment, vertigo or tinnitus leading to a reduced quality of life in the elderly. This study demonstrates the efficacy and acceptability of piribedil, a dopamine agonist, in improving these conditions. Of the 515 patients included in the study, there was complete resolution of memory impairment, vertigo and tinnitus in 103 patients (20%), improvement in 374 cases (72.6%), with 38 cases (7.4%) showing no change after one month's treatment with piribedil. The treatment was well accepted with a low frequency of side-effects and full compliance with daily medication.

Pathologic correlates of increased signals of the centrum ovale on magnetic resonance imaging.

The pathologic correlates of increased signal in the white matter of the centrum ovale in postmortem magnetic resonance imaging were investigated in an unselected series of 15 autopsies. Two types of magnetic resonance imaging hyperintensities could be separated on the basis of size (10-mm cutoff): extensive and punctate. The pathologic basis of extensive hyperintensities was large areas of pallor with ill-defined margins, located in the central white matter and sparing the subcortical U fibers on both myelin and axonal stains. Microscopically, these areas showed diffuse vacuolation and significant reduction in the areal densities of glial cells. This change was never seen in areas that did not show extensive white matter hyperdensities on magnetic resonance imaging. The correlates of punctate magnetic resonance imaging hyperintensities were less well defined; dilated Virchow-Robin spaces probably represent a common cause of this phenomenon.

Transrectal ultrasonic volume determination of the prostate--a preoperative and postoperative study.

A technique for transrectal ultrasonic volume determination of the prostate, based on the principle of serial planimetry, is presented. The preoperative ultrasonic determinations in 75 cases have been compared to the estimation of size by digital palpation and to the amount of tissue removed at operation. Scannings 6 to 10 weeks postoperatively have shown variable amounts of residual prostatic tissue. The difference in the preoperative and postoperative ultrasonic volume has been compared to the amount of tissue resected at operation, and the accuracy of the method has been established. The transrectal approach gives a close and complete view of the prostate, and has proved to be a simple, easily applicable and reliable method for volume determination. Postoperative scannings show morphological changes in the resection cavity, which are difficult to explain from scanning alone.
