    The relationship between child asthma admissions and biometeorological
    factors was investigated over a 16-month period. No relationship was
    found with many commonly suspected precipitants such as temperature,
    humidity and wind. There was however a strong association with
    rainfall (P much less than 0.001). Associations occurred with low
    barometric pressure and counts of coloured basidiospores and green
    algae, but no significant relationship was found with grass pollen.

    The observations carried out permit the following conclusions:

    STUDIES ON BLOOD FORMATION AND DESTRUCTION IN THE POLYCYTHEMIA OF HIGH
    ALTITUDE
    CÉSAR F. MERINO M.D.1
    1 Department of Pathological Physiology and the Institute of Andean
    Biology of the Faculty of Medicine, Lima, Peru.

    Studies of blood formation and destruction in the polycythemia of high
    altitude have been carried out. Three different groups of subjects
    were studied:

    1. Healthy adult male subjects from sea level who, after being studied
    at this level, were taken to an altitude of 4,540 meters (Morococha)
    where they developed a marked polycythemic process. When these
    subjects returned to sea level, the mechanisms of recuperation of the
    hematologic equilibrium were studied.

    Normal adult subjects, natives of high altitude, chronically
    polycythemic due to their permanent residence in Morococha, who were
    first studied in their native town and then brought to sea level where
    they were observed during five weeks.

    3. Subjects, residents of high altitude (Morococha), who had lost
    their adaptation to it; i.e. who had developed chronic altitude
    sickness or Soroche (Monge's malady).

    The observations carried out permit the following conclusions:

    1. The polycythemic process of subjects with anoxia caused by a low
    pressure environment is due to a greater blood formation by the
    hematopoietic organs. This becomes manifest after forty-eight hours.
    The very discreet polycythemia frequently found during the first hours
    is probably the result of hemoconcentration and release of stored
    blood.

    2. This polycythemic process is not accompanied by quantitative
    alterations of the leukocytes nor of the platelets; thus, differing
    from polycythemia vera, in which there is as a rule an increase in all
    the hematologic elements.

    3. The increased blood volume of residents at high altitude is due
    exclusively to the increased red cell mass, the plasma volume being
    more likely to be found diminished.

    4. In normal subjects who are temporarily or permanently exposed to an
    atmosphere of low barometric pressure, the excretion of fecal
    urobilinogen does not exceed the limits considered normal at sea
    level, but increases with relation to the larger circulatory
    hemoglobin mass, a normal hemolytic index being maintained.

    5. The hyperbilirubinemia very frequently found in the natives and in
    those resident for a long time at high altitudes appears to be related
    to a lesser excretion of this pigment by the liver, probably on the
    basis of the anoxic state. The greater production of bilirubin in
    subjects at high altitude is not sufficient to explain, in and of
    itself, the pigmentary elevation in the blood.

    6. The mechanism of the disappearance of the polycythemia when the
    subjects from a high altitude are brought to sea level, appears to be
    as follows: (a) temporary diminution or inhibition of erythropoiesis,
    and (b) a greater blood destruction. The latter takes place only
    during the first days of stay at sea level, being chiefly responsible
    for the early rapid decrease of the degree of polycythemia, while the
    former acts in a more prolonged form and is principally responsible
    for the erythropoietic "normalization."

    7. In two cases of chronic altitude sickness, or chronic Soroche
    (Monge's disease), the output of fecal urobilinogen exceeded
    proportionally the increase of the circulatory hemoglobin mass. The
    hemolytic index was found abnormally high.

    8. The above findings indicate that the polycythemia of the normal
    individual residing at high altitudes is characterized by a
    proportional and direct accentuation in the processes of blood
    formation and destruction. On the other hand, in those subjects also
    residing at high altitudes, who exhibit an abnormally high
    polycythemia (chronic Soroche), the accentuation in the processes of
    blood destruction is proportionally greater than that corresponding to
    the greater erythropoiesis. This characteristic constitutes a possible
    diagnostic criterion and can perhaps explain in part the etiologic
    mechanism of this alteration.

  2. I know that I sometimes have "migraines" when the barometer is very
