Prospective data at Framingham and elsewhere have shown conclusively that risk of coronary heart disease in persons younger than age 50 is strikingly related to the serum total cholesterol level. Within so-called normal limits risk has been found to mount over a five-fold range. The impact has been found to be augmented by other risk factors. ⋯ A relatively large amount of cholesterol in the low-density lipoprotein fraction is atherogenic, whereas that in the high-density fraction appears protective. The independent contribution of very-low density lipoprotein and its triglyceride or cholesterol content has, on the other hand, not been established. The previous position that virtually all of the lipid information pertaining to coronary heart disease resided in the serum total cholesterol must be accordingly modified.

We undertook a literature review to document whether certain therapeutic measures could be considered safe during pregnancy in the allergic patient. With the possible exception of brompheniramine, the commonly used antihistamine drugs appear to be safe during pregnancy. The bronchodilators ephedrine and theophylline also appear to be safe, as does cromolyn. ⋯ Because side effects are reduced when steroids are administered as aerosols in the nose or lung, these preparations seem well suited for use in pregnancy. The safety of allergic immunotherapy has been confirmed. For asthma, annual influenza vaccination is indicated.
