THE COMMON COLD—FACT AND FANCY

A great deal of folklore, superstition and emotional reaction is attached to the common cold, but established objective information is quite limited. The evidence concerning etiology, epidemiology, physiology, prevention and treatment of the common cold is briefly summarized and critically evaluated. There is disappointing lack of real progress in any of these aspects of the common cold problem.     

THE INSECTICIDES—Their Hazard in Industry and in the Home Part II—Clinical Aspect

Within the past decade the chemist has evolved a new group of insecticides having a greater range of toxicity to insects—and to man. Since their use is ubiquitous, it is imperative that information be widely disseminated regarding proper cautionary measures as well as the early signs and symptoms of toxicity.     

PANCREATITIS AND CARCINOMA OF THE PANCREAS—Some Aspects of the Pathologic Physiology

The physiological phenomena accompanying pancreatic disease in adults are related to the local and generalized reaction of the body to the blockage and/or leakage of the three enzymes—amylase, lipase and trypsin. The measurements of amylase and lipase in the serum are the most reliable criteria in the diagnosis of acute disease. Related changes may include hypocalcemia, hypopotassemia, hyperlipemia, hyperglycemia and decreased renal function.In chronic pancreatitis, there is less fluctuation in the amounts of the enzymes in the blood. The presence of diabetes mellitus, demonstration of calculi by x-ray, and examination of the stools for excess fat and meat fibers are more important diagnostic guides.In cancer of the pancreas, function tests using secretin stimulation of the gland followed by an examination of the external secretion or determination of the serum amylase have been used with some success.
