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 …

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 …

Indications For Cardiac Pacing, Paul M. Zoll Jan 1971

Indications For Cardiac Pacing, Paul M. Zoll

MCV/Q, Medical College of Virginia Quarterly

The indications for implantation of a long-term cardiac pacemaker consist of two major categories--the prevention of Stokes-Adams attacks and an inadequate cardiac output caused by a slow ventricular rate.


Collusion In Multiple Choice Examinations, S. J. Kilpatrick Jr. Jan 1971

Collusion In Multiple Choice Examinations, S. J. Kilpatrick Jr.

MCV/Q, Medical College of Virginia Quarterly

Many medical schools have now adopted multiple choice examinations and computer grading. The computer may also be used to detect or confirm collusion between students in these examinations. In the following, a method is given for calculating the probability that two given answer sheets by chance agree to the extant observed.

Current Trends In College Health Medicine, Philip B. Chase Jan 1971

Current Trends In College Health Medicine, Philip B. Chase

MCV/Q, Medical College of Virginia Quarterly

All the complex factors which are bringing about changes in college education--economic, social, political, and cultural--are profoundly affecting college health medicine. These changes are occurring with unusual rapidity, and are certainly causing strains to the old establishment thought to be so secure and unassailable a few years ago. However, in the new trends--student participation in the work of the Health Service, expansion of the work of the Health Service to include the entire college community, and the coming age of the Mental Health Program--we recognize new and more effective ways to deliver health care to our college youth and their …

The Use Of Principal Component Analysis To Increase The Ability Of Multiple Choice Examinations To Distinguish Among Students, Flora E. Roger, Walter H. Carter Jr. Jan 1971

The Use Of Principal Component Analysis To Increase The Ability Of Multiple Choice Examinations To Distinguish Among Students, Flora E. Roger, Walter H. Carter Jr.

MCV/Q, Medical College of Virginia Quarterly

A method of scoring multiple choice examinations based on the statistical technique of principal components analysis is described. This test is applied to two tests. The results indicate that the method yields test scores which have a marked advantage over the usual percentage scores in distinguishing among examinees with respect to knowledge of subject matter. In addition, the method provides an indication of whether a question is "good" or "poor" for purposes of distinguishing among examinees.
