A modest proposal: board certification for medical educators (or quis custodiet ipsos custodes?).

So that medical educators themselves will not be deprived of the benefits of certification, a brief written examination is offered as a first step. While the examination questions initially appear to be as obscure as those found on other certifying examinations, on further consideration they are found to be illustrative of certain basic concepts of medical education that are thought to be enduring, though not currently popular.

An internist looks at the fundus oculi.

The ophthalmoscope is the only convenient device permitting the in vivo inspection of both neural tissue and the arterial and venous blood columns within the retinal vessels. Many findings of little interest to ophthalmologists are, when integrated into the total clinical examination, of great use to internists during the process of making a specific diagnosis. Even after the diagnosis has been made, some ophthalmoscopic signs are uniquely useful in evaluating the chronicity, severity, prognosis, and/or the vasculopathic effects of the disease.

On pulsus paradoxus.

An abnormal amount of pulsus paradoxus may be produced in normal volunteers, for teaching purposes, by having them inspire and expire against resistance.

Munchausen's syndrome and the technologic imperative.

A patient with Munchausen's syndrome is reported. We note that certain technologic advances of the last three decades seem to have increased the possibilities for confusion when applied to a patient with this particular disorder.

Quincke, de Musset, Duroziez, and Hill: some aortic regurgitations.

Four peripheral signs of aortic insufficiency are considered in terms of their original descriptions, their popularity, and their potential future clinical contribution. It is concluded that: (1) Quincke's capillary pulse sign is not useful. (2) de Musset's head bobbing sign is of undetermined but apparently low sensitivity and specificity. (3) Duroziez's femoral double intermittent murmur sign, as modified by Blumgart and Ernstene, is almost 100% specific for the diagnosis of aortic insufficiency. Since its sensitivity, when properly performed, is about 90%, especially in pure aortic insufficiency, it is highly recommended. (4) Hill's sign (a popliteal indirect systolic blood pressure which is 20 mm Hg greater than a simultaneously measured brachial indirect systolic blood pressure) though almost unknown, is useful in diagnosing all but the mild cases of aortic insufficiency, and is the only sign that may predict the degree of aortic insufficiency subsequently found angiographically.

Diagnostic strategies.

A simple model of a universe of disease is presented. It permits the numerical comparison of different diagnostic strategies. Those diagnostic strategies exclusively using laboratory tests of perfect sensitivity and perfect specificity are shown to be inferior to a diagnostic strategy that begins with clinical information of unknown, but imperfect, sensitivity and specificity. This is true, within the model, even if we assume a "perfect world" in which every disease is represented by a "perfect" laboratory test.

Racial differences in normal values of proptosis.

Measurement of proptosis was made with a Luedde exophthalmometer by one experimenter in 402 black and 325 white adults without endocrine disease or obvious orbital pathologic conditions. Black subjects had significantly higher values of proptosis than white subjects. It is suggested that the following "upper limits of normal" be used when clinically estimating proptosis: 19 and 21 mm for white female and male patients, respectively; and 23 and 24 mm for black female and male patients, respectively.

Semantics of general medicine.

The words "education" and "training" are examined in the context of contemporary general internal medicine. Based upon the definitions of these two words, the words "practical" and "management" are assuming new meanings which reflect an approach to the patient distinct in a number of ways from the classic one. Conflict may arise when members of two groups attribute distinct and differing meanings to the single word.
