Survival in acute myocardial infarction; factors observed in 318 patients.

Factors influencing survival in a group of 318 cases of acute myocardial infarction were analyzed. The mortality rate for the entire series was 41 per cent. Among the men it was 39.5 per cent; among women, 44.4 per cent. The mortality rate increased with the age of the patient. Twenty-six per cent of all deaths occurred within the first 24 hours, 44 per cent within 72 hours, and 71 per cent within the first week following hospital admission. Increased mortality rate was associated with previous history of congestive failure, myocardial infarction, hypertension or cardiomegaly. As to circumstances immediately preceding an infarction, the only ones that seemed to be related to a high mortality rate were hemorrhage and the postoperative state. Not only the presence but the degree of shock, congestive failure, cyanosis and dyspnea adversely influenced chances for survival. Duration, location, radiation and number of attacks of pain did not appear to be associated with extraordinary mortality rates. Anterior was slightly more common than posterior infarctions, and the mortality rate was much higher. Thromboembolic complications and certain disorders of rhythm and of conduction definitely worsen prognosis. Comparison of average mortality data as reported in different studies on acute myocardial infarction is improper and misleading because of the great differences between the kinds of patients included in various series reported upon. A standard method of grading the severity of acute myocardial infarction would help toward sounder comparisons.

Multiple myeloma; a review of 26 cases.

Multiple myeloma is a rare, malignant disease of bone marrow which affects principally the vertebrae, ribs, pelvis and skull but may involve any part of the skeleton. Severe demineralization and destructive lesions of bones, producing severe pain and debility, are distinctive features. The disease is further distinguished by abnormalities of blood proteins and in some cases by the excretion in the urine of Bence-Jones protein, which seldom, if ever, is found in association with any other disease.X-ray examination is frequently helpful. In 22 of 24 cases (of a series of 26 cases) in which films were available, definite abnormalities were noted. Spontaneous fractures, particularly of vertebrae, are common. The diagnosis of the disease rests on the identification of the myeloma cell. This is best accomplished by aspiration of bone marrow. In several of the 26 cases in the series diagnosis was made by a neurosurgeon at the time of operation to relieve pressure on the spinal cord. The myeloma cell has a very characteristic appearance. In the present series the average duration of life after the onset of symptoms was only nine months. One patient, however, survived for at least ten years.
