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.
Deaf-blindness refers to a child with both hearing and visual disabilities. According to National Dissemination Center for Children with Disabilities (abbreviated as NICHCY), deaf-blindness does not necessarily mean complete losses. NICHCYâs fact sheet on this disability category states, âthe word âdeaf-blindnessâ may seem as if a person cannot hear or see at all. The term actually describes a person who has some degree of loss in both vision and hearing. The amount of loss in either vision or hearing will vary from person to person.â.
