|September 4, 2018
Summary
This case highlights a rare instance of undifferentiated pleomorphic sarcoma developing seven years after a radiation burn from coronary catheterization. It underscores the importance of monitoring radiation exposure and patient follow-up due to potential malignancy risks.
Area of Science:
- Oncology
- Radiology
- Medical Malignancy
Background:
- Coronary stent placement involves radiation exposure (6-11 mSv), exceeding background levels.
- Radiation exposure carries inherent risks of genetic mutation and secondary malignancy.
Observation:
- A 75-year-old male developed an exophytic mass on his back.
- The mass appeared seven years after a radiation burn from coronary catheterization.
Findings:
- Biopsy confirmed the mass as undifferentiated pleomorphic sarcoma.
- The sarcoma originated at the site of the previous radiation burn.
Implications:
- This case emphasizes the rare but serious risk of radiation-induced sarcoma.
- Strict monitoring of radiation exposure and long-term patient follow-up are crucial for early detection of potential malignancies.

02:59Biological Effects of Radiation
18.0K
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they...

The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.

01:21Coronary Circulation
7.3K
The heart, an organ critical to survival, gets nourishment not from the blood it pumps but from a separate circulation system known as coronary circulation. This is the shortest circulation in the body and is responsible for supplying the heart with the nutrients it needs to function effectively.
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...

6.4K
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.

01:09Radiation Pressure: Problem Solving
850
The radiation pressure applied by an electromagnetic wave on a perfectly absorbing surface equals the energy density of the wave. The wave's momentum also gets transferred to the surface when an electromagnetic wave is entirely absorbed by it. The rate at which momentum is transmitted to an absorbing surface perpendicular to the propagation direction equals the force on the surface.
The average value of the rate of momentum transfer divided by the absorbing area represents the average force...
