1908
massachusetts and missouri were the first states to require a driver's license in 1903, but there was no test associated with the license. “in 1908, henry ford launched the model t, the first affordable automobile for many middle-class americans. (in 1919, when ford’s native state of michigan started issuing driver’s licenses, he got his first one at age 56.) the same year the model t debuted, rhode island became the first state to require both a license and a driver’s exam (massachusetts instituted a chauffeur exam in 1907 and started requiring tests for all other drivers in 1920). california, now known for its car culture, started requiring licenses in 1913 and exams in 1927.” it was not until 1959 that all the states required a license for the driver.

if there are no signs of infection, a cyst of montgomery can be observed, because more than 80% resolve spontaneously, over only a few months. however, in some cases, spontaneous resolution may take up two years. in such cases, a repeat ultrasonography may become necessary. if, however, the patient has signs of an infection, for example reddening (erythema), warmth, pain and tenderness, a treatment for mastitis can be initiated, which may include antibiotics and non-steroidal anti-inflammatory drugs (nsaids). with treatment, inflammatory changes usually disappear quickly. in rare cases, drainage may become necessary. a surgical treatment of a cyst of montgomery, i.e. a resection, may become necessary only if a cyst of montgomery persists, or the diagnosis is questioned clinically.
