    Page 299, Pregestational diabetes and Pregnancy

    The text says “Observed in 1% of all pregnancies”

    Uptodate says 13% “Pregestational diabetes (ie, diabetes diagnosed before pregnancy, type 1 or type 2 diabetes mellitus) comprises approximately 13 percent of all diabetes in pregnancy,”

    Oops, sorry, misread the uptodate article. 1% still seems like a really low number.

    In regards to First Aid Q & A for USMLE Step 1, in the pharmacology section, the answer choices to #7 do not correlate to the question. Anyone have the explanations for the question?

    I got a question on my ck about MMR and I remembered that your book said MMR is contraindicated in egg allergy. I put it as answer trusting first aid- unfortunately I didn’t know that this book is full of errors. Please could you start working on publishing a new edition. People trust your brand and I don’t want more people get wrong answers because of this book. I think CK writers have caught on on your mistakes and now can easily get people who took CK before a certain rotation and have to rely on your book on info.

    FA for Step 2 CK, 8th Ed, Page 503:
    Contraceptive methods that protect against PID: OCPs and barrier contraception.

    Per UpToDate:
    Oral contraceptives (OCs) have a complex interaction with PID… women using OCs appear to develop PID in response to cervical initiating agents about as frequently as other women, but the severity of the infection — with respect to both symptoms and tissue damage — is substantially diminished.

    P. 247 Carotid endarectomy indications are correct but your correction to this in the errata pdf is incorrect.

    FA Q&A 3rd ed. Question 46 answer-page 49.

    The statement for “Answer D is incorrect” …is incorrect–it is a duplication of the statement for question 37.

    The statement for “Answer C is incorrect” refers to answer D, not C.

    There is no statement explaining why the actual answer C is incorrect.

    The Romberg test covers the myelinated dorsal columns (proprioception) of the spinal cord. It isn’t a test of cerebellar function! If you have a bad cerebellum you won’t be able to undergo the test.

    Lumbar spinal stenosis patient will be + Romberg’s ~90% of the time

    In page 51 on First Aid for the USMLE Step 1 2014, it is written that NPV varies inversely with prevalence or pretest probability: high pretest probability = low NPV. It should be NPV varies inversely with prevalence and directly with pretest probability ; high pretest probability = high NPV

    First Aide, Q & A, Step 1, third edition;
    Page 34, question 12 (correct answer B) , last sentence:
    B(beta) Thalassemia is more common among Mediterranean populations, whereas B(beta)-thalassemia is more common among Asian and African populations”. It appears the error is the later and the Asian African populations should be ‘Alpha’ not “beta’.
    Please correct me if I am wrong. TY

    Page 214, Marginal answer A2
    “Salmonella is the most common organism that causes osteomyelitis in patients with sickle cell disease” instead of “S aureus”

    In the general population, S aureus is the most common organism causing osteomyelitis. However, in patients with sickle cell disease, S aureus accounts for less than 25% of cases of osteomyelitis.
    Whether Salmonella or S aureus is the most common cause of osteomyelitis has been a source of debate; however, meta-analysis of the available studies supported that the majority of cases are due to Salmonella.

    This isn’t errata so to speak, but it’s worth noting.

    Do you guys realize all the notes you have written won’t fit or comply with the USMLE Step 2 CS system? They have a practice site where you can use the actual system you type on test day (limited by 15 lines and 950 characters for the history then also for the physical).

    It’s funny that many of your notes won’t fit and exceed the 15 lines / 950 characters. Just using the first 5 or 6 cases, I believe more than half didn’t comply. This is kind of important because if you exceed it the rest of your note is not allowed to be inputted. Basically you are teaching the notes to be longer than allowed.

    Also, case 9 has a sexual assault victim.

    The assault was 3 hrs ago. You state to order a pregnancy test and that’s recommended. Also you state that it’s important to order this in the closing section.

    Pregnancy tests don’t turn positive for like over a week in the serum and even longer than that in the urine. How in the world can you order a pregnancy test 3 hrs after assault unless you are thinking she was pregnant before the assault?

    First Aid Q&A for the USMLE Step 1, 3rd ed., page 452, question 2. According to the answers, the patient has spontaneous pneumothorax and the correct answer is E. Answer E states that the patient will have tracheal deviation to the ipsilateral side and an elevated diaphragm on the R side. According to First Aid for the USMLE Step 1 2014 (page 608), there is no tracheal deviation with a spontaneous pneumothorax.
