Mechanisms of pulmonary edema clearance: from basic research to clinical implication

Mechanisms of pulmonary edema clearance.

The mechanisms of pulmonary edema resolution are different from those regulating edema formation. Absorption of excess alveolar fluid is an active process that involves vectorial transport of Na+ out of alveolar air spaces with water following the Na+ osmotic gradient. Active Na+ transport across the alveolar epithelium is regulated via apical Na+ and chloride channels and basolateral Na-K-ATPa...

Trichothiodystrophy: from basic mechanisms to clinical implications.

Trichothiodystrophy (TTD) is an autosomal recessive disorder with symptoms affecting several tissues and organs. The most relevant features are hair abnormalities, physical and mental retardation, ichthyosis, signs of premature aging and cutaneous photosensitivity. The clinical spectrum of TTD varies widely from patients with only brittle, fragile hair to patients with the most severe neuroecto...

Mechanisms of neurogenic pulmonary edema.

The pulmonary edema that develops quickly after a variety of cerebral insults, such as head injury, epileptic seizures, intracranial hypertension, and subarachnoid hemorrhage, is often accompanied by rapid flooding of airways with a protein-rich edema fluid (Weisman, 1939; MacKay, 1950; Richards, 1963; Simmons et al., 1968; Ciongoli and Posner, 1972; Theodore and Robin, 1976; Fisher and AboulNa...

Mathematical Modelling of Pulmonary Edema

The excess accumulation of water in lung interstitial or alveolar is called pulmonary edema which is caused by factors that upset the normal Starling balance in micro-circulation. Pulmonary edema disturbs the alveolar gas exchanges which are normally regulated by the respiratory system. Mathematical modelling of pulmonary edema may help to predict the lung conditions and the mechanisms involved...
