Following a single 150 mg IM dose of DEPO-PROVERA Contraceptive Injection, medroxyprogesterone acetate concentrations, measured by an extracted radioimmunoassay procedure, increase for approximately 3 weeks to reach peak plasma concentrations of 1 to 7 ng/mL.
Deafness can increase until it is almost impossible to hear any sound, but it has been found that most deaf persons can hear at least one sound. If a person is totally deaf, he cannot hear a thing including his own voice. Some people are born deaf, and some lose their hearing from disease or other causes. Most hearing problems are caused by diseases that do not necessarily start in the ear but reach it from some other part of the body.
The difference between hearing loss and deafness. Hearing loss refers to a diminished ability to hear sounds like other people do, while deafness refers to the inability to understand speech through hearing even when sound is amplified. Profound deafness means the person cannot hear anything at all; they are unable to detect sound, even at the highest volume possible.
