New Horizons In Psychiatry, James L. Mathis Jan 1971

New Horizons In Psychiatry, James L. Mathis

MCV/Q, Medical College of Virginia Quarterly

Psychiatrists have long held that there should be more psychiatry in general medicine, and the nonpsychiatric physicians have said that there should be much more medicine in psychiatry. Both groups have been perfectly correct and are being told by the consuming population that there must be more sociology in each of them. The future psychiatrist must and will work with his colleagues in medicine, not to achieve a utopia, but at least to approach this desirable situation in some degree.

Psychology Of Drug Abuse, John Buckman Jan 1971

Psychology Of Drug Abuse, John Buckman

MCV/Q, Medical College of Virginia Quarterly

The history of drug abuse is as long as history. While all drugs are being abused, this paper has attempted only to elucidate some of the psychological reasons why the western adolescent might be attracted to excessive drug use or experimentation. There has grown in the past 8 years a great interest in drugs which produce an altered state of consciousness. It is the opinion of this writer that the adolescent years may be the worst years to experiment with the strong hallucinogens like LSD, mescaline, or psilocybin. The adolescent is already under enormous pressure, both from within and without, …

His Bundle Recordings, Onkar S. Narula Jan 1971

His Bundle Recordings, Onkar S. Narula

MCV/Q, Medical College of Virginia Quarterly

When we record atrial activity on the His bundle electrogram we are recording from the area of the atrium which is around the tricuspid valve, that is, the lower part of the right atrium. The normal range of conduction time from the region of the sinus node to the low right atrium is about 25 to 45 milliseconds.

Alternative Methods Of Grading One Or More Multiple Choice Examinations, S. J. Kilpatrick Jr. Jan 1971

Alternative Methods Of Grading One Or More Multiple Choice Examinations, S. J. Kilpatrick Jr.

MCV/Q, Medical College of Virginia Quarterly

This paper describes the use of the standardized score in grading multiple choices examinations by computer. Since standardized scores make no allowance for guessing, it is recommended that the percent of questions known be used instead, and that a student who correctly answers significantly fewer than a predetermined number of questions be given a failing grade.

New Developments In Screening For Inborn Errors Of Metabolism, Peter Mamunes Jan 1971

New Developments In Screening For Inborn Errors Of Metabolism, Peter Mamunes

MCV/Q, Medical College of Virginia Quarterly

I have briefly outlined the PKU program in the State of Virginia and tried to demonstrate how this screening experience has disclosed the heterogeneity of the disease plus the need for an individualized approach to dietary control. I have applied the principles of mass screening to examine the feasibility of testing for other inborn errors and, on this basis, feel that galactosemia will soon next join with PKU. Mass screening for other aminoacidopathies will await more refined testing techniques and a definition of their incidence and mode of therapy. In the meantime, accumulated experience thus far mandates the establishment of …

Effect Of Freezing And Thawing On Uptake Of Amino Acids Into Human Erythrocytes, Richard Moore, Rita Parenti, I. Rena Bizios Jan 1971

Effect Of Freezing And Thawing On Uptake Of Amino Acids Into Human Erythrocytes, Richard Moore, Rita Parenti, I. Rena Bizios

Journal of the Minnesota Academy of Science

ABSTRACT - The transport of "C-amino acids into human erythrocytes and into erythrocytes which had been frozen and thawed was studied experimentally. The relative rates of uptake were found to be (in decreasing order): phenylalanine, leucine, alanine, trythophan, and glycine. Freezing (using gycerol as the cryoprotective additive) and thawing had no significant effect on either the magnitude of the rate constants or on the order of the above relative rates of amino acid uptake into erythrocytes suspended in isotonic TRIS-HCl buffer.

Historical Development Of Cardiac Pacing, Paul M. Zoll Jan 1971

Historical Development Of Cardiac Pacing, Paul M. Zoll

MCV/Q, Medical College of Virginia Quarterly

I would like to discuss the development and historical aspects of cardiac pacemaking from a personal point of view, presented as it appeared to me over the years. This approach is biased, selective, and incomplete, but I think as informative as I can make it.

Autoerthrocyte Sensitization Or Psychogenic Purpura?, Thomas G. Smith Jan 1971

Autoerthrocyte Sensitization Or Psychogenic Purpura?, Thomas G. Smith

MCV/Q, Medical College of Virginia Quarterly

The following report describes the occurrence, in four women, of an abnormal response to bruising, characterized by local pain, swelling, and extension of bleeding into adjacent areas, often to a serious extent. The histories and laboratory investigations suggest that, in these patients, there has occurred a sensitization against one of their own body tissues, namely red blood cells.

Electrical Instrumentation And Hazards, Barouh V. Berkovits Jan 1971

Electrical Instrumentation And Hazards, Barouh V. Berkovits

MCV/Q, Medical College of Virginia Quarterly

Electric current is both valuable and hazardous in cardiac therapy. Small amounts of electric current are enough to electrocute the patient, especially if the current is delivered through a catheter in the heart. It has been demonstrated that currents as low as 10-15 microamperes are capable of inducing ventricular fibrillation. This minute amount of current is actually a thousand times less than what you can barely feel with your hand; nevertheless, this amount of current, internally, can cause many problems. Therefore, electrical equipment, when used, must be used carefully. We must be careful of the amount of current induced by …

Pacemaker Concepts And Terminology, Barouh V. Berkovits Jan 1971

Pacemaker Concepts And Terminology, Barouh V. Berkovits

MCV/Q, Medical College of Virginia Quarterly

Since the introduction of implantable cardiac pacing systems there have been marked advances in concept and design of the equipment available. Whereas intracardiac pacing is usually identified with A-V conduction disturbances, recently gained knowledge of cardiac physiology has shown that electrical stimulation of the heart can be beneficial in the treatment of many arrhythmias. It is important that the physician familiarize himself with the different modalities of pacing. The terminology used to describe the different concepts must be clear and precise so the physician can select the proper pacemaker concept for his patient without ambiguity.

Pacemaker Clinic, Victor Parsonnet Jan 1971

Pacemaker Clinic, Victor Parsonnet

MCV/Q, Medical College of Virginia Quarterly

Pacemaker longevity is a serious problem to overcome. However, our immediate concern is to get as much useful life from a pacemaker as possible. On the average, pacemakers fail in about 23 months. The only pacemaker that lasted much longer was a fixed-rate unit, the Medtronic 5860, which is no longer available. A past suggestion in handling this problem has been to change the pacemaker electively at an arbitrary time, but that time has varied tremendously as the manufacturers once selected 30 months, and more recently 15 months. If a pacemaker is replaced at 15 months, very few of them …

Electrocardiographic Recognition Of The Various Pacemaker Types And Dysfunction, Leonard S. Dreifus Jan 1971

Electrocardiographic Recognition Of The Various Pacemaker Types And Dysfunction, Leonard S. Dreifus

MCV/Q, Medical College of Virginia Quarterly

This discussion deals with electrocardiographic interpretations of the various types of pacemakers as well as with their dysfunction which may be due to pulse generator failure, wire breakage, change in threshold, or polarization of the ventricle. Hemodynamic problems may also arise concerning placement of the pacemaker leads particularly in those patients who lack atrial contribution.

The Adolescent And Competitive Athletics, Isao Hirata Jr. Jan 1971

The Adolescent And Competitive Athletics, Isao Hirata Jr.

MCV/Q, Medical College of Virginia Quarterly

An attempt has been made to view the adolescent in organized athletics--sympathetically and understandingly. In doing so, an admittedly-biased vantage point has been selected-the better to evaluate the philosophical desirability of competition, as of itself, and, secondary thereto, the positive or negative value of organized competitive athletics. Since, philosophy or no, athletic programs have long been established in almost every conceivable sport and in almost every age group from grade-school onwards, a pattern of organized medical care to cope with this established need has been advocated, much as it already exists in most colleges, large and small. Based on experience …

Land Use In Wah Wah And Pine Valleys, Western Utah, Joseph R. Murdock, Stanley L. Welsh Jan 1971

Land Use In Wah Wah And Pine Valleys, Western Utah, Joseph R. Murdock, Stanley L. Welsh

Brigham Young University Science Bulletin, Biological Series

This is a review of the use of public lands in Wah Wah and Pine Valleys in western Utah for grazing of livestock, mining, and other private enterprises. The total area of the two valleys is approximately 1,440 square miles of which about 30 square miles are privately owned. From the time grazing of domestic livestock was initiated in the 1870's and 1880's until 1934, the land was free public domain and was grazed on a first-come, first-served basis. Passage of the Taylor Grazing Act in 1934 ended free use of public lands. Existing evidence indicates that by 1934 the …
