In this paper, we present a new computational framework for the simulation of airway resistance, the fraction of exhaled nitric oxide, and the diffusion capacity for nitric oxide in healthy and unhealthy lungs. Our approach is firstly based on a realistic representation of the geometry of healthy lungs as a function of body mass, which compares well with data from the literature, particularly in terms of lung volume and alveolar surface area. The original way in which this geometry is created, including an individual definition of the airways in the first seven generations of the lungs, makes it possible to consider the heterogeneous nature of the lungs in terms of perfusion and ventilation.

Unlabelled: It is known that in most cases of congenital central hypoventilation syndrome (CCHS), apnoeas and hypoventilation occur at birth. Nevertheless, a detailed description of initial symptoms, including pregnancy events and diagnostic tests performed, is warranted in infants with neonatal onset of CCHS, that is, in the first month of life. The European Central Hypoventilation Syndrome Consortium created an online patient registry from which 97 infants (44 females) with CCHS of neonatal onset and PHOX2B mutation from 10 countries were selected.

Ex vivo confocal laser scanning microscopy (EVCM) is a novel diagnostic method for bedside use with the possibility to perform rapid dermatopathological examinations on fresh tissue, while directly creating digital pictures. The aim of this article is to provide an overview of current study results in the field of EVCM. Due to the large number of studies in dermatology, the focus is set on the diagnosis of dermatological diseases.

Lung cancer is still diagnosed at an advanced stage due to lack of early disease symptoms. We have techniques and equipment for rapid on site evaluation of pulmonary lesions. However, with new technology or a combination of technologies in the diagnostic suite the cost of biopsy is rising.

The use of rapidly applied limited array continuous EEG (rapid EEG) has become technologically feasible in recent years. Nurse-led protocols using rapid EEG as a point-of-care monitor are increasingly being adopted.
