Bloodstream infections (BSIs) are infections of blood caused by blood-borne pathogens. [1] The detection of microbes in the blood (most commonly accomplished by blood cultures [2]) is always abnormal. A bloodstream infection is different from sepsis, which is characterized by severe inflammatory or immune responses of the host organism to ...
While many infectious agents can infect the adrenals, an acute, selective infection is usually meningococcus. [3] Pseudomonas aeruginosa can also cause WFS. [4] WFS can also be caused by Streptococcus pneumoniae infections, a common bacterial pathogen typically associated with meningitis in the adult and elderly population. [2]
Necrotizing pneumonia (NP), also known as cavitary pneumonia or cavitatory necrosis, is a rare but severe complication of lung parenchymal infection. [ 1 ] [ 2 ] [ 3 ] In necrotizing pneumonia, there is a substantial liquefaction following death of the lung tissue, which may lead to gangrene formation in the lung.
Fever of unknown origin (FUO) refers to a condition in which the patient has an elevated temperature for which no cause can be found despite investigations by one or more qualified physicians. [1] [2] [3] If the cause is found, it is usually a diagnosis of exclusion, eliminating all possibilities until only the correct explanation remains.
Meningococcemia, like many other gram-negative blood infections, can cause disseminated intravascular coagulation (DIC), which is the inappropriate clotting of blood within the vessels. DIC can cause ischemic tissue damage when upstream thrombi obstruct blood flow and hemorrhage because clotting factors are exhausted. Small bleeds into the skin ...
Infection with GBS can cause serious illness and sometimes death, especially in newborns, the elderly, and people with compromised immune systems. The most severe form of group B streptococcal disease is neonatal meningitis in infants, which is frequently lethal and can cause permanent neuro-cognitive impairment .
The final report of the U.K.'s infected blood inquiry was published on Monday, nearly six years after it began looking into how tens of thousands of people contracted HIV or hepatitis from ...
The concentration of this cytokine is usually very low or non-detectable in young adults though levels increase in old age and are very high in the elderly. [2] Moreover, elevated IL-6 has also been associated with disability and mortality in older adults. High serum levels are associated with cognitive impairment, low locomotion, and ...
