Radiation proctitis or radiation proctopathy is a condition characterized by damage to the rectum after exposure to x-rays or other ionizing radiation as a part of radiation therapy. [1] Radiation proctopathy may occur as acute inflammation called "acute radiation proctitis" (and the related radiation colitis) or with chronic changes ...
Acute radiation syndrome (ARS), also known as radiation sickness or radiation poisoning, is a collection of health effects that are caused by being exposed to high amounts of ionizing radiation in a short period of time. [1] Symptoms can start within an hour of exposure, and can last for several months.
Radiation enteropathy represents the longer-term, chronic effects that may be found after a latent period most commonly of 6 months to 3 years after the end of treatment. In some cases, it does not become a problem for 20–30 years after successful curative therapy.
Side effects of radiation therapy might occur after a few weeks into treatment. Both types of radiation therapy may cause diarrhea and mild rectal bleeding due to radiation proctitis, as well as potential urinary incontinence and impotence. Symptoms tend to improve over time except for erections which typically worsen as time progresses.
The medical effects of the atomic bomb upon humans can be put into the four categories below, with the effects of larger thermonuclear weapons producing blast and thermal effects so large that there would be a negligible number of survivors close enough to the center of the blast who would experience prompt/acute radiation effects, which were observed after the 16 kiloton yield Hiroshima bomb ...
bowel problems. Some patients (less than 10%) report an increase in bowel problems (diarrhea or urgency of the bowels), but again this usually settles down without further treatment. [ 18 ] Radiation proctitis can be found in 0.5–21.4% of patients who received prostate brachytherapy due to the proximity of the prostate and the large bowel ...
Radiation therapy can have a significant impact on female fertility. The damage induced varies greatly and is determined by factors such as the age of the patient along with the dose and duration of treatment given. [1] Estimates suggest that less than 2Gy of radiation could destroy half of a female’s immature oocytes.
The risk of systemic infection is higher when the organism has a combined injury, such as a conventional blast, thermal burn, [3] or radiation burn. [2] There is a direct quantitative relationship between the magnitude of the neutropenia that develops after exposure to radiation and the increased risk of developing infection. Because no ...
