Transmission of Mycobacterium tuberculosis undetected by tuberculin skin testing.

abstract：:Typical for critical illnesses are substantial alterations within the hypothalamic-anterior pituitary-peripheral hormonal axes that are proportionate to the risk of poor outcome. These neuroendocrine responses to critical illness follow a biphasic pattern. The acute phase (first hours to days) is characterized by an i...
