Infant respiratory distress syndrome (IRDS), also known as surfactant deficiency disorder (SDD), [2] and previously called hyaline membrane disease (HMD), is a syndrome in premature infants caused by developmental insufficiency of pulmonary surfactant production and structural immaturity in the lungs.
Causes may include sepsis, pancreatitis, trauma, pneumonia, and aspiration. [1] The underlying mechanism involves diffuse injury to cells which form the barrier of the microscopic air sacs of the lungs , surfactant dysfunction, activation of the immune system , and dysfunction of the body's regulation of blood clotting .

Complex regional pain syndrome is uncommon, and its cause is not clearly understood. CRPS typically develops after an injury, surgery, heart attack, or stroke. [ 8 ] [ 12 ] Investigators estimate that 2–5% of those with peripheral nerve injury, [ 13 ] and 13–70% of those with hemiplegia (paralysis of one side of the body) [ 14 ] will ...
Medically unexplained physical symptoms (MUPS or MUS) are symptoms for which a treating physician or other healthcare providers have found no medical cause, or whose cause remains contested. [1] In its strictest sense, the term simply means that the cause for the symptoms is unknown or disputed—there is no scientific consensus .
Oxygen toxicity is a condition resulting from the harmful effects of breathing molecular oxygen (O 2) at increased partial pressures.Severe cases can result in cell damage and death, with effects most often seen in the central nervous system, lungs, and eyes.
Also called volumic airway resistance. Due to the elastic nature of the tissue that supports the small airways airway resistance changes with lung volume. It is not practically possible to measure airway resistance at a set absolute lung volume, therefore specific airway resistance attempts to correct for differences in lung volume at which ...

The World Health Organization has reported that, "At a global level, 7 of the 10 leading causes of deaths in 2021 were noncommunicable diseases, accounting for 38% of all deaths, or 68% of the top 10 causes." [4] Historically, many NCDs were associated with economic development and were so-called a "diseases of the rich". The burden of non ...
