The serum anion gap (AG) is a calculated value defined as the difference between the sum of sodium and potassium and the sum of chloride and bicarbonate concentrations. Thus, the anion gap is equal to the unmeasured cations minus the unmeasured anions (UA). To evaluate the AG changes during HDF-on line, we studied 20 patients treated with this technique. ⋯ The increase in serum albumin and pH can mask an decreased concentration of unmeasured anions in patients treated with HDF on-line. An adjusted anion gap without effect of CAA and CAP can be obtained. With the help of this adjustments the changes in some undetermined anions organic and inorganic (sulphate and others in renal failure) can be calculated.

The accuracy of the reference list is considered an essential factor in determining the quality of a scientific publication, and has been reviewed and published in several medical journals. The rate of citation errors in NEFROLOGIA has not been published before. The aim of this study has been to examine the accuracy of the references citation in the numbers of the journal published for a period of 15 years, from the first issue in 1981 to the last one on 1995. ⋯ The issues of NEFROLOGIA published in this period present a high number of bibliographic reference errors, being the rate similar to other evaluated scientific periodical journals. This fact should be improved, and authors and reviewers should thoroughly check their references in order to avoid these mistakes, as they affect the quality standard of the publication.
