This study examined the acid-base disturbances in 67 adults with salicylate intoxication. On admission, 66 patients had an acid-base distrubance. In contract to previous suggestions, however, only 25% of the patients had simple respiratory alkalosis. ⋯ These additional drugs generally were CNS depressants and were important determinants of the variety of the acid-base disturbance. Those patients who ingested additional drugs had a significantly lower incidence of respiratory alkalosis (P less than .005) and a higher incidence of respiratory acidosis (P less than .005) and acidemia (P less than 0.25). The incidence of acidemia correlated with the presence of neurological symptoms.

Total mortality showed no association with coffee usage in the four race-sex groups of Evans County, Georgia. Deaths of coronary heart disease (CHD) in white men and women and black men showed no statistically significant difference between high and low coffee consumers. ⋯ However, to refute or confirm the allegations of a detrimental influence of high coffee intake, larger samples are needed. Nevertheless, our finding that mortality from all causes is not increased in the high coffee-consuming group means that a finding of increased CHD mortality with high coffee consumption would have to be compensated by a protective lower rate for other causes of death.
