The major motor disturbances in Parkinson's disease are thought to be caused by overactivity of the internal segment of the globus pallidus (GPi), in large part due to excessive drive from the subthalamic nucleus. The excessive inhibitory activity of GPi is thought to "brake' the motor thalamus and the cortical motor system to produce the slowness, rigidity, and poverty of movement characteristic of parkinsonian states. To test the hypothesis that direct reduction of Gpi activity can improve motor function, we studied the effect of GPi pallidotomy in 14 patients. The location of the GPi nucleus was confirmed by microelectrode recording before lesion creation. Standardised videotape recordings before and after operation were randomised and scored by a "blinded' evaluator. 6 months after surgery, total motor score in the "off" state had improved by 30% and the total akinesia score by 33%. The gait score in the "off" state improved by 15% and a composite postural instability and gait score by 23%. After surgery there was almost total elimination of drug-induced involuntary movements (dyskinesias), with a 92% reduction on the side contralateral to the pallidotomy. No patient had visual or corticospinal complications. In these patients GPi pallidotomy enhanced motor performance, reduced akinesia, improved gait, and eliminated the neural elements responsible for levodopa-induced dyskinesias.
The rapid development and incorporation of minimally invasive surgical techniques has abruptly changed adult surgical practices. These minimally invasive procedures are now being successfully applied to pediatric surgical problems. The anticipated benefits of these techniques include less postoperative pain, quicker return of bowel function, shorter hospital stay, and lower hospital costs, with a quicker return to normal activity. This report compares the first 60 infants and children to undergo laparoscopic gastrostomy and/or fundoplication at our institution with the same number of patients that underwent these procedures in the traditional open fashion. The two groups were similar with respect to age, sex, concurrent illness, presenting symptoms, neurological status, and procedures performed. Patients in the laparoscopic group were found to have shorter mean hospital and postoperative stays and tolerated feeding earlier. The mean hospital stay was 13.8 days for the laparoscopic group versus 16.4 days in the open group. The mean postoperative stay was 6.8 days for the laparoscopic group versus 10.7 days for the open group. The mean postoperative day on which feeding was tolerated was 2.3 in the laparoscopic group versus 4.8 in the open group. Postoperative complications were similar between the two groups. These results seem to reflect the less traumatic nature of the laparoscopic procedures as compared with the open procedures. Laparoscopic fundoplication and gastrostomy is an attractive alternative to open fundoplication and gastrostomy in infants and children.
Because the ultimate goal of trauma care is to restore injured patients to their former functional status, reliable evaluation of functional status is needed to assess fully the effectiveness of trauma care. We hypothesized that the Sickness Impact Profile (SIP), a widely used measure of general health status, would be a useful tool to evaluate the long-term functional outcome of trauma patients and that the SIP would identify unexpected problems in the recovery process and groups of patients at high risk for long-term disability. A prospective cohort of 329 patients with lower extremity fractures admitted to three level I trauma centers were interviewed using SIP at 6 and 12 months postinjury. Patients with major neurologic injuries were excluded. Overall SIP scores and each of the component subscores may range from 0 (no disability) to 100. In this series, the mean overall SIP was 9.5 at 6 months and 6.8 at 12 months, compared with a preinjury baseline of 2.5. At 12 months, 52% of patients had no disability (SIP 0 to 3), 23% mild disability (4 to 9), 16% moderate disability (10 to 19), and 9% severe disability ( > or = 20). Disability was widely distributed across the spectrum of activities of daily living, including physical functioning (mean score of 5.5), psychosocial health (mean score of 5.5), sleeping (mean score of 10.0), and work (mean score of 21.0). The SIP scores did not correlate with Injury Severity Score.(ABSTRACT TRUNCATED AT 250 WORDS)
