The course of a respiratory disorder in a child may end up in respiratory failure. There are also acute non-respiratory diseases which have a great influence on the respiratory functions and often lead to the acute lung injury and sometimes to the acute respiratory distress syndrome (ARDS). A feature of respiratory function deterioration is changed in the surfactant system. We often see inhibit...

BACKGROUND Initially described as an early onset seizure variant of Rett syndrome, the CDKL5 disorder is now considered as an independent entity. However, little is currently known about the full spectrum of comorbidities that affect these patients and available literature is limited to small case series. This study aimed to use a large international sample to examine the prevalence in this dis...

       Asthma, which is mainly distinguished by airway inflammation and bronchial hyper responsiveness, is known as one of the most common chronic diseases worldwide. It also is the most frequent chronic respiratory disorder amongst all age groups. On one side of the asthma story, there are massive investment of time, effort and money, a large number of pharmaceutical and academic research stud...

In neuromuscular diseases, respiratory disorder is related to sleep disorder. In Duchenne muscular dystrophy, respiratory muscle disorder progresses and induces alveolar hypoventilation. Hypoxemia and hypercapnia develop, requiring appropriate management. Hypoxemia first appears during sleep, initially occurring during the REM period, and it progresses and becomes persistent. Not only a decreas...

Hypoventilation increases PaCO(2) (hypercapnia) and initiates the acid-base disorder known as respiratory acidosis. Hyperventilation decreases PaCO(2) (hypocapnia) and initiates the acid-base disorder known as respiratory alkalosis. The impact on acidity of these primary changes in PaCO(2) is ameliorated by secondary, directional changes in plasma bicarbonate concentration that occur in two sta...
