First Aid Errors
Page #ErrorSourceUnder Debate?
87PEP to Pyruvate should be irreversible (one-way arrow)found in Lippincott's Biochem glycolysis section (the 2nd edition on the bottom of p. 92)
103Heme synthesis: There is an arrow going from Lead Poisoning to ALA Synthetase. It shouldn't be there. Heme inhibits ALA synthase so just change the arrow. Heme (or more specifically hemin (oxidized heme that builds up when there is more production of heme than consumption) acts as a negative feedback inhibitor on ALA Synthase so this way more protoporhyrin isn't made.Lippincott's biochem pg 277
141Enterohemorrhagic E. coli (EHEC) is associated with O157:H7, not EIEC.Pg 56 in Micro Made Ridiculously Simple
146Coccidiomycosis and Histoplamosis are transmitted by inhalation of spores. Add Blastomycosis to that list.Page 147-148 of Micro Made Ridiculously Simple
191Psoriasis alone is associated with HLA B13 and B17. Psoriatic arthritis is associated with HLA B27.??? Ask phillip wortley
221The graph on the top right. Switch ESV and EDV.figure on page 217 in our pathophysiology of heart disease book
255Pseudohypoparathyroidism has several different modes of inheritance, not only recessiveThis is under debate-- several sources disagree ask Fadi or Emmy******
259GH (somatostatin) should be GH (somatotropin)DUH!
267Figure: points to two mediaL umbilical ligaments. The one on the RIGHT is the mediaN umbilical ligament. Recall: umbilical arteries are mediaL and the urachus is mediaN.Netters and BRS gross anatomy ask emmy for pages
279"In Hepatocellular jaundice, the Urine Bilinogen should be increased (not normal or low). This is from Lippincott's Biochem page 283. Now, this is in contradiction to page 264 of BRS Pathology which also says that Urine Bilinogen is normal/low. The explanation from Lippincott's makes a lot of sense as to why its high so it might be worthwhile to go with their explanation...Lippincott's Biochem pg 264
323On the bone drawing showing tumor locations, osteochondroma (exostosis) should be pointing at the metaphysis (not diaphysis as is in the picture).Ask Phil wortley
324Temporal Arteritis...should say Most common vasculitis that affects medium and large arteries not medium and smallpg 337 of Lilly
324Poly Arteritis Nodosa...should say associated with P-ANCAEmedicine: (section 4 http://www.emedicine.com/NEURO/topic314.htm), BUT BRS Path (3rd ed.) Pg. 128: polyarteritis nodosa does NOT involve glomeruli (differentiating it from Wegener granulomatosis and microscopic polyangiitis) and is NOT associated with ANCA. This information is from Robbins (pg. 539) and corresponds to what is in First Aid. BUT Lilly says it has to do with pANCA***
343Vagal nuclei: First Aid states that the dorsal motor nucleus sends autonomic (parasympathetic) innervation to the heart. Although all other vagal autonomic innervation comes frmo the dorsal motor nucleus the heart's innervation comes from the nucleus ambiguus.Dr. Blankenship and Nolte on page 375.
344Cavernous sinus syndrome – ophthalmoplegia, ophthalmic and MAXILLARY sensory lossextrapolated from anatomy. http://www.medterms.com/script/main/art.asp?articlekey=9157
346Light reflex...light in either retina sends a signal via CNIII...should be CNII high yield neuroanatomy pg 94; pg 282-283 OF BRS Neuro; p. 542 in essential clinical anatomy
353under spinal cord lesions the diagram with syringomyelia says that the corticospinal tract is damaged but we all know that it is the spinalthalamic tract that is damaged. Figure 8.3 on Page 147 of BRS Neuro
385For SLE under nephrotic syndrome, the "wire-loop" lesion is most often seen with thediffuse proliferative pattern (which is more nephritic also) with subendothelial deposits. The membranous pattern is associated with subepithelial deposits (not subendothelial) and only sometimes has the wire-loop pattern--ie. when the nephropathy is regressing from proliferative to membranous after treatment.Renal Pathophysiology (Blue book) page 228-229
398Testosterone, not androstenedione, is converted by aromatase to make estrogen (17-beta estradiol).Page 289 of BRS Phys
489RNA ribonucleic acid...should read...RNA (ribonucleic acid)Ask Archie's Mother
