Part of a daily project to visualize facts I'm studying for the medicine step 2 boards. Day #14 Thyroid Cancer Thyroid cancers consist of papillary, follicular, medullary, and anaplastic types. They are listed from most common to least as well as best prognosis to least. Medullary (central) carcinomas are found in calcitonin producing C cells of the thyroid.
Part of a daily project to visualize facts I'm studying for the medicine step 2 boards. Day #28 Alcoholics, Magnesium, Vegans, and B12 Alcoholics frequently have magnesium (magnum gun) deficiencies and pure vegans eventually will deplete stores of B12. B12 deficiency causes anemia, gastritis, and demyelination of DC/LCSP tracts, and SCT leading to ataxic gait, impaired position/vibration sense. Mg deficiency causes weakness, muscle cramps, hypocalcemic tetany.
why do our ears hurt and pop in airplanes? It boils down to unequal pressure between our external auditory canal (arrow) and middle ear (#2). Changes in altitude change the pressure outside the eardrum (#1), but the middle ear doesn’t respond as quickly. This pressure difference cause the membrane to distort which is painful. The middle ear is connected to the nasopharynx (#4) by the eustachian tube (#3). This tube is closed—when we swallow it opens which allows the pressure to equalize.
