Importance of Holter monitoring in patients with periodic cerebral symptoms.

Holter monitoring was used in 358 patients with symptoms of intermittent dizziness, blackout, or both. The neurological findings in all patients were normal. None manifested evidence of a pertinent arrhythmia on the one-minute resting ECG; 8.9% of the patients demonstrated arrhythmias known to correlate with cerebral symptoms; and 11.2% demonstrated "predisposing" arrhythmias, ie. rhythms that in and of themselves may not precipitate symptoms but predispose to arrhythmias that do. The latter category included short bursts of ectopic tachycardia and intermittent short-duration asystole. High-frequency ectopic beats were observed in 24.6%. In almost every patient in whom intermittent arrhythmias precipitated symptoms there were many "predisposing" arrhythmias of short duration that occurred during the asymptomatic period. A comparison of 12- and 24-hour recordings demonstrated an increase in pertinent arrhythmias from 13.8 to 22.7%.

Copayment and national health insurance in the United States: a critique of work by Newhouse, Phelps, and Schwartz.

In "Policy Options and the Impact of National Health Insurance," Newhouse, Phelps, and Schwartz concluded that any national health insurance program which did not provide for high user copayments, particularly for ambulatory services, would swamp, and ultimately wreck, the health care delivery system, particularly for ambulatory services. This paper presents a detailed critique of their work. Three major points of criticism are raised: First, Newhouse et al. have engaged in some questionable methodological practices. Second, they fall into a serious contradiction in gathering evidence to support their basic postulate. Third, they adopt a unidimensional view in proposing solutions to the problems which they predict will arise. From these criticisms, the conclusion is drawn that Newhouse et al. failed to prove their case.

The 1974 reorganization of the British National Health Service: an analysis.

The British National Health Service was reorganized on April 1, 1974, for the first time since its formation in 1948. The Reorganization attacked one serious problem: the anomalous separation of the general practitioners (and other nonhospital, non-local authority ambulatory services), hospitals, local government authority public health services, and teaching hospitals into different administrative units with different boundaries. These services are now integrated into one structure. However, other important problems will not be affected substantially.

Neurogenic bladder in normal pressure hydrocephalus.

Five patients wíth normál pressure hydrocephalus who had urinary incontinence were found to have neurogenic bladders by cystometry. The bladder disturbance in this disorder whould be considered the result of a specific defect of brain function and not just and artifact of gait disturbance or of dementia.

Comparison of dopa decarboxylase inhibitor (carbidopa) combined with levodopa and levodopa alone in Parkinson's disease.

A double-blind study comparing the effects of carbidopa and levodopa combined in a single tablet with levodopa alone was undertaken in 50 patients with Parkinson's disease. After 6 months, there was a statistically significant improvement over baseline in total score, rigidity, and tremor only in the patients randomized to carbidopa/levodopa. In addition, 40 percent of the patients treated with carbidopa/levodopa showed obvious clinical improvement (a greater than 50 percent reduction in their total score) over treatment with levodopa alone. However, after 2 years, only 20 percent continued to show this improvement. Nausea, vomiting, and anorexia developed in 56 percent of patients on levodopa but in only 27 percent of patients on carbidopa/levodopa. However, abnormal involuntary movements, observed in 48 percent of patients on levodopa, were present in 77 percent of patients on carbidopa/levodopa. Despite the increase in abnormal involuntary movements, carbidopa/levodopa is more effective than levodopa.
