Changes in liver structure are an important issue in chronic hepatopathies. Until the end of the 20th century, these changes could only be determined by histological analyses of a liver specimen obtained via biopsy. The well-known limitations of this technique (i.e., pain, bleeding and the need for sedation) have precluded its routine use in follow-up of patients with liver diseases. However, the introduction of non-invasive technologies, such as ultrasound and magnetic resonance imaging, for measurement of liver stiffness as an indirect marker of fibroses has changed this situation. Today, several non-invasive tools are available to physicians to estimate the degree of liver fibrosis by analysing liver stiffness. This review describes the currently available tools for liver stiffness determination that are applicable to follow-up of liver fibrosis/cirrhosis with established clinical use in children, and discusses their features in comparison to the “historical” tools.

Objective We evaluated the development of ICU survival of patients with hematopoietic malignancies and discussed changes in admittance policies. Method We compared 166 patients treated between 2009 and 2012 with 138 patients treated between 2013 and 2016. Patient characteristics and outcome were analyzed. Results ICU survival was 45.2% in the first group and 66.7% in the second (P < 0.0005). Infection (P = 0.033), invasive ventilation (IMV) (P = 0.014) and SOFA score at day 3 (SOFA‐48h) (P = 0.007) independently indicated worse ICU survival in the first group, IMV (P = 0.013) and SOFA‐48h (P = 0.019) in the second group. The second group showed lower frequencies of infection (P = 0.003), IMV (P < 0.0005), need for vasopressors (P < 0.0005) and RRT (P = 0.021) at ICU admittance than the first. Further, the accumulation of hyperkaliemia, acidosis, low bicarbonate, high lactate and hypotension showed worse ICU survival in both groups and was lower in second group. Conclusion ICU survival increased distinctly between 2009 and 2016. At ICU admittance, parameters showing severity of illness were less frequent in the second group. Our findings indicate general treatment improvements especially of infections and changes of admittance policies toward early ICU admittance during time.
