Review Comparative Study
The assessment of acid-base analysis: comparison of the "traditional" and the "modern" approaches.
Three distinct approaches are currently used in assessing acid-base disorders: the traditional - physiological or bicarbonate-centered approach, the base-excess approach, and the "modern" physicochemical approach proposed by Peter Stewart, which uses the strong ion difference (particularly the sodium chloride difference) and the concentration of nonvolatile weak acids (particularly albumin) and partial pressure of carbon dioxide (pCO(2)) as independent variables in the assessment of acid-base status. The traditional approach developed from the pioneering work of Henderson and Hasselbalch and the base-excess are still most widely used in clinical practice, even though there are a number of problems identified with this approach. ⋯ Although Stewart's approach has been largely ignored by physiologists, it is increasingly used by anesthesiologists and intensive care specialists, and is recommended for use whenever serum's total protein, albumin or phosphate concentrations are markedly abnormal, as in critically ill patients. Although different in their concepts, the traditional and modern approaches can be seen as complementary, giving in principle, the same information about the acid-base status.

To determine differences in emotional profile and frequencies of certain risk behaviours between tattooed and non-tattooed students. ⋯ Results of this research as well as previous research show that the presence of a tattoo could be a rough indicator for possible emotional problems and risk behaviour, which could have significant implications in preventing these behaviours. Future studies are required on a larger and more representative sample as well as to clarify why young people decide to be tattooed.
