The accuracy of magnetic resonance imaging in patients with suspected multiple sclerosis. The Rochester-Toronto Magnetic Resonance Imaging Study Group
Authors: A. I. Mushlin
Journal: JAMA (1993)

<h3>Objective.</h3> —To design and implement a methodologically rigorous study to examine the accuracy of magnetic resonance imaging (MRI) in a patient population clinically suspected of having multiple sclerosis (MS). <h3>Design and Setting.</h3> —Three hundred three patients, who were referred to two university medical centers because of the suspicion of MS, underwent MRI of the head and double-dose, contrast-enhanced computed tomography (CT) of the head. The images were read by two observers individually and without knowledge of the clinical course or final diagnosis. Patients were followed up for at least 6 months and reevaluated clinically with subsequent neurological examination. Final diagnosis (MS or not MS) was made by a panel of neurologists on the basis of the clinical findings at presentation, those that developed during follow-up, and other diagnostic tests. The results of the imaging procedures were excluded to avoid incorporation bias. Diagnostic accuracy was assessed using receiver-operating characteristic analysis and likelihood ratios. <h3>Results.</h3> —Magnetic resonance imaging of the head was considerably more accurate than CT in diagnosing MS. The area under the receiver-operating characteristic curve for MS was 0.82 (compared with 0.52 for CT) indicating that MRI was a good but not definitively accurate test for MS. A "definite MS" reading on an MRI of the head was specific for MS (likelihood ratio, 24.9) and essentially established the diagnosis, especially in patients clinically designated as "probable MS" before testing. However, MRI of the head was negative for MS in 25% and equivocal in 40% of the patients considered to have MS by the diagnostic review committee (sensitivity, 58%). <h3>Conclusions.</h3> —Magnetic resonance imaging of the head provided assistance in the diagnosis of MS when lesions were visualized. Its ability far exceeded imaging with double-contrast CT. The sensitivity and, therefore, the predictive value of a negative MRI result for MS were, however, not sufficiently high for a normal MRI to be used to conclusively exclude the diagnosis of MS.

How many patients are necessary to assess test performance?
Authors: C. F. Arkin
Journal: JAMA (1990)

Test performance characteristics are important in assessing the clinical usefulness of laboratory tests and serve as a basis for comparing one test to another. Statistical comparisons of performance characteristics are meaningful only when they can detect medically important differences; that is, when they provide adequate statistical power. This requires choosing the appropriate sample size in determining the performance characteristics of interest. Using standard formulas, we designed tables that provide such sample size requirements. Example problems of sample size determination in laboratory test comparisons are given. Used appropriately, this approach should result in better studies of laboratory tests and fewer meaningless negative studies. (<i>JAMA</i>. 1990;263:275-278)

Reports on the Nursing and Administration of Provincial Workhouses and Infirmaries
Journal: BMJ (1894)

THE workhouse stands in the middle of tlhe little country town of the same name, and harmonises well with its sur- roundings; it is a flint building of irregular outline, with casement windows.It is approached by a drive, bordered by gay and well-kept flower beds.As in so many of these Norfolk districts, the population of the neighbourhood has de- clined, or has improved in circumstances, so that the number of beds in the workhouse greatly exceeds the demand.The house is licensed for about 250, and at the time of our visit the inmates numbered 70.Twenty-eight beds are set apart for the sick. THIE INFIRMARYis part of the house; the whole building is vely old, and in many ways quite unsuited for its work.We visited the dayrooms first, and the old people were called in from the yards by the master and matron to see us.THE DAY-ROOMS are fairly comfortable, with benches placed on either side

<h3>Chapter III.</h3> Algid Form:—"As a general rule, the vascular action was much below par in the algid form. I have observed cases in which the radial pulse was imperceptible for days; more commonly, however, the pulse at the worst, though excessively feeble, was not altogether obstructed, and by a delicate and practiced finger it could be felt and counted. Its rate was variable, more commonly below than above 100 per minute. I have noted it at 80, very fine, thready, weak and readily extinguishable, and at almost all intermediate rates to 120, with much the same character. The cardiac action was very feeble. I have not observed any diminution in the relative proportions of the first and second sounds of the heart; they were often diminished in tone and force, but preserved their relative characters of duration and intensity. I have not observed any want of accordance between the cardiac
Norovirus Outbreak Associated With Ill Food-Service Workers—Michigan, January-February 2006
Journal: JAMA (2008)

On January 30, 2006, the Barry-Eaton District Health Department (BEDHD) in Michigan was notified of gastrointestinal illness in several members of two dining parties after a meal at an Eaton County restaurant on January 28. An investigation was initiated by BEDHD to identify the source and agent of infection and to determine the scope of illness among patrons and employees of this national chain restaurant. Norovirus genogroup I (GI) was detected in stool specimens submitted by multiple patrons and employees. The investigation revealed that several food-service workers had been ill during January 19-February 3, 2006, and that a line cook had vomited in the restaurant on January 28, possibly increasing environmental contamination and transmission of virus. This report summarizes the findings of the outbreak investigation, which determined that at least 364 restaurant patrons had become ill. The findings underscore the need for 1) ongoing education of food-service workers regarding prevention of norovirus contamination and transmission; 2) enforcement of policies regarding ill and recently ill food-service workers; and 3) environmental decontamination with effective disinfectants to eliminate the presence of norovirus.
Interstate Reciprocity.

Journal: JAMA (1906)

Detroit, March 10, 1906. <h3>To the Editor:</h3> —Dr. George W. Webster states in reply to my letter inThe Journal, March 3, 1906, in which I interpret his proposed plan of action to make practical his basis of reciprocity as in conflict with the authority and purposes of state medical boards, and in which also I suggest that his committee could be effective from a standpoint of education working in harmony with the Association of American Medical Colleges—as follows: "I regret very much that Dr. Harison seems to have utterly failed to grasp the fundamental ideas which I tried to convey, namely: that the American Medical Association is desirous of assisting the examining boards, and that the plan proposed is not simply a scheme of reciprocity but a proposed plan of education. which, if successfully carried out, will serve as a rational foundation on which reciprocity will naturally
Major body burn
Authors: C. P. Artz
Journal: JAMA (1973)

Major burns have been a serious problem in the United States for many years. According to the National Health Survey for the years 1957 to 1961 there are 1,973,000 injuries annually. Of these, 268,000 require bed care. Statistics compiled by the US Department of Health, Education, and Welfare for the year 1960 show that there were 7,645 deaths due to accidents resulting from fire and explosion. The death rate during this period was 4.3/100,000 population.<sup>1</sup> <h3>Causes.—</h3> Thermal burns most commonly result from contact with hot liquids or metals, explosions (flash burns), or flames. Scald burns are most common in children under 3 years of age. They frequently result from bathtub accidents or the overturning of containers of hot liquids by inquisitive youngsters. In the 3- to 15-year age group, major burns usually result from the misuse of fire or matches. The ignition of clothing from open fires and heaters
Role of peripheral autonomic neurones in maintaining adequate cardiac function
Authors: J.A. Armour, J.L. Ardell, M. Horackova, J.A. Armour, J.L. Ardell, J.A. Armour, J.A. Armour, J.L. Ardell
Journal: Cardiovascular Research (1995)

This review has focused on the putative effects that peripheral autonomic neurones exert on cardiac myocytes. Through data obtained by the use of in situ and in vitro models, the unique synaptology and chemical sensitivities of the various types of neurones in intrinsic cardiac and extracardiac intrathoracic ganglia are becoming evident. The intrathoracic nervous system acts as a distributive network, processing in a complex fashion information that arises not only from cardiac, vascular and pulmonary tissues but also from extrathoracic tissues, to maintain adequate cardiac function. In challenging the current understanding of cardiac regulation, this view provides novel opportunities to develop pharmacological and surgical strategies to manipulate cardiac function in disease states.
