Syndrome of inappropriate antidiuretic hormone secretion (SIADH), also known as the syndrome of inappropriate antidiuresis (SIAD), [2] is characterized by a physiologically inappropriate release of antidiuretic hormone (ADH) either from the posterior pituitary gland, or an ectopic non-pituitary source, such as an ADH-secreting tumor in the lung.

In medicine, the Faget sign—sometimes called sphygmothermic dissociation—is the unusual pairing of fever with bradycardia (slow pulse). (Fever is usually accompanied by tachycardia (rapid pulse), an association known by the eponym "Liebermeister's rule".)
It is the most common bacterial pneumonia found in adults, the most common type of community-acquired pneumonia, and one of the common types of pneumococcal infection. The estimated number of Americans with pneumococcal pneumonia is 900,000 annually, with almost 400,000 cases hospitalized and fatalities accounting for 5-7% of these cases. [2]
Pneumococcal infection is an infection caused by the bacterium Streptococcus pneumoniae. [ 1 ] S. pneumoniae is a common member of the bacterial flora colonizing the nose and throat of 5–10% of healthy adults and 20–40% of healthy children. [ 2 ]
CURB-65, also known as the CURB criteria, is a clinical prediction rule that has been validated for predicting mortality in community-acquired pneumonia [1] and infection of any site. [2] The CURB-65 is based on the earlier CURB score [3] and is recommended by the British Thoracic Society for the assessment of severity of pneumonia. [4]
The phase of resolution and/or remodeling following bacterial infections is commonly referred to as organizing pneumonia, both clinically and pathologically. The American Thoracic Society and the European Respiratory Society hold that "cryptogenic organizing pneumonia" is the preferred clinical term for this disease for multiple reasons: [ 6 ...
Demeclocycline inhibits the renal action of antidiuretic hormone by interfering with the intracellular second messenger cascade (specifically, inhibiting adenylyl cyclase activation) after the hormone binds to vasopressin V 2 receptors in the kidney. [18] [19] [20] Exactly how demeclocycline does this has yet to be elucidated, however. [20]
Occult pneumonia is a pneumonia that is not observable directly by the eye, but can only be shown indirectly, especially by radiography. Occult pneumonia can be made visible by chest X-rays . The general symptoms cough for more than 10 days and fever for more than 3 days can indicate the presence of occult pneumonia, just as a temperature of 39 ...
