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
