    Lets keep going

    Advertisements



    A 20 year old man complains of diarrhea, burning of the throat and dificulty swallowing over 3 months. On examination he has mild jaundice and transverse white striae of the finger nails. There is alsi evidence of peripheral neuropathy.

    The BEST Diagnostic tool would be:
    A-Endoscopy
    B-Liver Biopsy
    C-Arsenic
    D-SCL-70 Antibodies
    E-Chronic Megavaluemditis

    The correct answer is C --- Arsenic

    Wile there is no clue to exposure(insecticides,woodperserveratives) the clinical picture is characteristic of arsenic poisoning.

    The white transverse line in the finger nails is from chronic arsenic poisoning. Actually is called Aldrich-Mees lines.
    Arsenic combined with the globin part of hemoglobin to produce hemolysis.

    Remember Bio terrorism= biologicalweapens they can ask in the exam at least 1-2
