摘要:

What seem to be rare complications of common diseases may merely be uncommon because no one accumulates a large number. The unusual combination of disseminated nodular bone formation in the lungs and chronic mitral stenosis is more common in young men. The clinical findings in 4 cases are described and the pathogenesis is discussed.

摘要:

Approximately 95 per cent of patients with patent ductus have characteristic machinery murmurs. Five per cent have only systolic murmurs. In such patients, the intravenous or intramuscular administration of a pressor substance, mephentermine, may bring out a continuous murmur. This simple test is a useful adjunct in diagnosis.

摘要:

Observations were made on the growth of the anastomotic site 2 to 4 years after surgical resection of coaretation of the aorta in 5 infants who were less than 2 years of age at the time of surgery. Aortic measurements were made from biplane angiocardiograms. The physiologic adequacy of the anastomotic site was demonstrated by absence of a gradient in direct pressure measurements between the upper and lower extremities. Additional observations on the normal growth of the descending thoracic aorta were made from studies in 154 subjects with other forms of heart disease. They ranged in age from 2 days to 74 years.

摘要:

A case is reported of primary venous obstruction in the upper extremity, the Paget-Schroetter syndrome. The literature of this unusual condition is reviewed and the mechanism of its development and its treatment is discussed.

摘要:

Oral administration of chlorothiazide depresses glomerular filtration, increases blood urea, maintains sodium output in the face of decreased filtered sodium load, and paradoxically for a diuretic, in these and in tests done shortly after intravenous administration, increases the efficiency of water reabsorption.

摘要:

Chlorothiazide decreases plasma volume, heart size, and cardiac output. The oligemia stimulates vasomotor tone; this tends to maintain arterial pressure because chronic arterial hypertension is characteristically self-sustaining and homeostatic. This oligemic stimulation of vasomotor tone results in increased sensitivity to the antihypertensive effect of drugs depressing or blocking vasomotor function.

摘要:

Because of reports that derivatives of Rauwolfia serpentina may cause severe mental depression when used in the treatment of hypertension, the depressive reactions and possible contributing factors were studied in a group of 387 hypertensive patients. Some of the patients received no specific antihypertensive medication; some were treated with Rauwolfia derivatives alone and some with Rauwolfia and other antihypertensive drugs. Of the patients receiving Rauwolfia, alone or with other drugs, 26 per cent experienced depressive reactions whereas only 5 per cent of the others had them.

摘要:

There has been no study of the efficiency of any sound-producing system. Here there is a description of a device that records the force of each pull applied to a valve segment or strip of myocardium while the sound evoked is recorded. The relation of force to sound intensity, and the attenuation of sounds in air, blood, and ventricular and chest walls provide some quantitative data on a neglected phase of cardiac physiology.

摘要:

Changes in pulmonary vascular (arteriolar) resistance were estimated in 58 patients with mitral stenosis following mitral valvotomy and during exercise. Evidence is presented that changes in "resistance" reflect active changes in the caliber of the vessels due to alteration in their smooth muscle tone, valvotomy being followed by a decrease in tone and exercise by an increase.
