Several cases of bilateral, symmetrical, diffuse, nodular, pulmonary densities assokted with rheumatic mitral st,cnosis were discovered in draftees. These miliary densities must be carefully Ilistinguishetl from similar appearing renditions, such as miliary tuberculosis, sarcoidosis, pneumonoconiosis, carcinomatosis, rtc.

Hospitals.

19.U.

There was a total of 3,475 admissions of patients with rheumatic infections to all hospitals in Cincinnati for the period from Jan. 1, 1930 to Dec. 31, 1940. Analysis of the records of these admissions and comparison with similar data obtained in Philadelphia for the perioll from 1930 through 1934 revealed the following facts : The rheumatic syndrome ~a?; more nearly the same in Negroes in the two cities than it was in white persons. Negroes constituted a considerably greater proportion of the patients with rheumatit heart disease with rheumatic fever, and a somewhat smaller proportion of those with chorea than would be expected from their proportion in the population and in patients admitterl to hospitals. Choroa is more Common in Negroes than is generally realized. In white persons in Cincinnati the incidence of rheumatic fever was lower, and the acute manifest,ations were less frequent, than in Philadelphia, and both morbidity aml c.ase mortality among rllildren were lower. Among adults above the age of 35 years? the annual incidence of rheumatic heart disease per hundred thousand of population was greater in (‘incinnati; this group accounted for more of thp patients who died in Cincinnati than in Philadelphia. Adequate cqonvalescent care for white children, and caomparatively inadequate length of hospitalization for adults in Cincinnati, provide a possihlr explanation for these differences. tend to corroborate the growing conviction The data accumulate(l in thi R survey that convalescent, care, of provr~l value for children with rheumatic fever, should he given also to young adults. This c*oncaept is of major importance in handling rheumatic infections among young persons in military serricc. .21’T110RS.

Investigation 23: 139, 1944. Major and minor outbreaks as well as sporadic cases of streptococcal pharyngitis occurring in groups of rheumatic children in a sanatorium (luring a six-year period are described. Major outbreaks were due to Group A streptococci of a single type not previously present, and were not precedrd by a rise in carrier rate. Minor outbreaks were prereded by a slow spread from carriers to other individuals without at first causing infection. Subsequently, a small number of clinical cases due to these types developed. Sporadic cases arose directly from carriers and were not preceded by a dissemination of the streptococci to healthy individuals,

Features

In this series of cases of hyperthyroidism the noteworthy electrocardiographic findings in order of frequency were: (1) sinus tachycasdia, (2) various abnormalities of the T waves, of which low amplitude and notching were the most common, (3) aurieular fibrillation, (4) partial auriculoventricular block, and (5) in rare instances, auricular flutter. After exclusion of other causes for electrocardiographic abnormalities, the incidence of these findings was the same for the younger (14 to 40 years of age) and for the older (41 to 75 years of age) groups of patients. After treatment of hyperthyroidism, the abnormalities tend to disappear. In the presence of hyperthyroidism, electrocardiograms must be interpreted with caution, since they may simulate those of persons with organic heart disease. AUTHORS.
