hydroxychloroquine
|
-disease-modifying anti-rheumatoid drug that causes retinal deposits (as side effect)
|
|
Waterhouse-Friderichsen syndrome
"NSAiD" |
= hemorrhagic adrenalitis
-Neisseria meningitidis septicemia -Shock (hypotension) -Adrenocortical insufficiency (with bilateral adrenal hemorrhage) -DIC, with purport on surface of skin -various proposed mechanisms of adrenal hemorrhage --> adrenal galnds converted into sacs of clotted blood |
|
Neisseria meningitidis
|
-gram-negative diplococcus
|
|
complement deficiency in MAC (C5b-C9)
|
-results in recurrent meningococcal infections, as well as Neisseria gonorrhoeae infections
|
|
C1 esterase inhibitor deficiency
|
-causes hereditary angioneurotic edema
|
|
C3 deficiency
|
-causes recurrent bacterial infections
|
|
adrenal gland viscerosomatic reflex
|
-sympathetic viscerosomatic relfex for adrenal glands are at T8-T10 ipsilaterally
-no known parasympathetic viscerosomatic reflex for adrenal glands |
|
Hepatic encephalopathy
|
-presents with history of cirrhosis, plus onset of personality change, lethargy, and disorientation
-symptoms are due to increased ammonia that enters brain -liver is damaged to point that it can no longer run urea cycle to get rid of excess ammonia -treatment of disease involves eliminating excess ammonia -- this is accomplished with LACTULOSE -another treatment option for hepatic encephlopathy is antibiotics --decreasing amount of gut bacteria will decrease production of ammonia by those bacteria |
|
Lactulose
|
-non-absorbable – broken down by gut bacteria to lactic acid
-this acidification of gut lumen leads to conversion of ammonia to ammonium ions – increases movement of ammonia from tissues into gut lumen |
|
Most important prognostic indicator in diagnosis of malignant melanoma
|
-depth of lesion
--staging based on depth of invasion in mm. -other criteria are the ABCDE criteria: --asymmetry, border irregularlity, color, diameter, evolution |
|
Neisseria infections
-types and associated immune deficiency |
-disseminated gonorrhea infection
-->arthralgia, tenosynovitis, ulcerative rash -Neisseria meningitidis = bacterial meningitis with associated rash -patients with C5-C9 complement deficiency are at increased risk for Neisseria infections --C5-C9 are final components of cascade responsible for membrane attack complex (MAC), which inserts holes in microbial membrane -deficiency in C5-C9 increases risk for Neisseria infections |
