In his book, Benjamin described "true" transsexualism as the following:

True transsexuals feel that they belong to the other sex, they want to be and function as members of the opposite sex, not only to appear as such. For them, their sex organs, the primary (testes) as well as the secondary (penis and others) are disgusting deformities that must be changed by the surgeons knife. Relationship to transgender
The term transgender was coined by John Oliven in 1965. By the 1990s, transsexual had come to be considered a subset of the umbrella term transgender. The term transgender is now more common, and many transgender people prefer the designation transgender and reject transsexual. Some people who pursue medical assistance (for example, sex reassignment surgery) to change their sexual characteristics to match their gender identity prefer the designation transsexual and reject transgender. One perspective offered by transsexual people who reject a transgender label for that of transsexed is that, for people who have gone through sexual reassignment surgery, their anatomical sex has been altered, whilst their gender remains constant.Historically, one reason some people preferred transsexual to transgender is that the medical community in the 1950s through the 1980s encouraged a distinction between the terms that would only allow the former access to medical treatment.
While some issues, such as a recent history of exposure to substantive toxins, can foretell the diagnosis, for a patient with dyphagia the diagnosis may be less obvious, as the dyphagic patient may have caustic gastric contents damaging the lungs which may or may not have progressed to bacterial infection. The following tests help determine how severely the lungs are affected:

Blood gases (measurement of how much oxygen and carbon dioxide are in your blood)
CT scan of chest
Lung function studies (tests to measure breathing and how well the lungs are functioning)
X-ray of the chest
Swallowing studies to check if stomach acid is the cause of pneumonitis

Treatment
Treatment is focused on reversing the cause of inflammation and reducing symptoms. Corticosteroids may be given to reduce inflammation, often before long-term scarring occurs. Antibiotics are usually not helpful or needed, unless there is a secondary infection. Oxygen therapy may be helpful. References
