Owner Reviews, Ratings, Comments and Criticism
Inadequate would be something that just doesn't prepare you well enough. Well, this book is worse than that since it has so many errors. I purchased this book in the PDF version. I am currently studying for the Micro/Path section right now and have only done about 40 of these questions. In just 40 questions I have found NUMEROUS errors and discrepancies. Some of the questions do not even correlate with the answer explanations, while other answers are flat out incorrect. For instance, there is a question about the ACTH test & Addison's disease. The question is fine and the answer choice is correct, however, the explanation for the answer is completely inaccurate. See below. 39.What does the ACTH stimulation test accomplish? A.Differentiates between primary and secondary hyperparathyroidism B.Differentiates between hyper- and hypothyroidism C.Differentiates between Cushing disease and syndrome D.Differentiates between primary and secondary Addison disease (correct answer) E.Differentiates between acromegaly and dwarfism 39.The correct answer is D. The ACTH stimulation test is used to differentiate between primary and secondary Addison disease. Primary Addison is due to autoimmune, infectious, neoplastic, or hemorrhagic damage to the adrenal cortex. Secondary Addison is caused by a decrease in ACTH from the pituitary gland, thus hypofunction of the adrenal cortex. Thus, the stimulation test is accomplished by administering ACTH exogenously to a suspect patient. (the above explanation is fine, but when they get to the most important part below, they SWITCH the reasoning!) If cortisol increases, then primary Addison is suspected (adrenal cortex still functioning). If cortisol levels stay the same, then secondary Addison is suspected. This is due to inability of the adrenal cortex to respond to the ACTH. You can check out these 2 links for a proper explanation if you need it. Basically, primary Addison's is a result of adrenal damage in one form or another, which would make it nearly unresponsive to exogenous ACTH depending on the degree of damage. For secondary (depending on the amount of time the pituitary was in hypofunction), you would see an increase in cortisol in response to injected ACTH. http://en.wikipedia.org/wiki/ACTH_stimulation_test http://en.wikipedia.org/wiki/Addison's_disease So I guess the point of this overly verbose rant is that I personally would like to study in peace and not wonder whether or not the material I am using is correct. And unfortunately this book is riddled with errors.
