Using X-rays To Treat Inner Ear Infections and Deafness

Dr. Edward Calabrese and G Dhawan have published an article titled Historical use of x-rays: Treatment of inner ear infections and prevention of deafness in Vol 33(5) of Human and Experimental Toxicology, May 2014.

Abstract
Purpose: This article provides an historical assessment of the role of radiotherapy in the treatment of inner ear infections.

Materials and methods: The research utilized a literature-based evaluation of the use of x-rays during the first half of the 20th century on the treatment of otitis media (OM), mastoiditis, and cervical adenitis and their impact on the occurrence of deafness.

Results: X-Rays were consistently found to be effective as a treatment modality at relatively low doses, in the range of 10–20% of the skin erythema dose, rapidly reducing inflammation, and accelerating the healing process. The mechanistic basis of the clinical successes, while addressed by contemporary researchers, is evaluated in the present article in light of current molecular biology advances, which indicate that clinically effective low doses of ionizing radiation act via the creation of an anti-inflammatory phenotype in highly inflamed tissue.

Conclusions: X-Ray treatment of OM, mastoiditis, and cervical adenitis was widely accepted in the first half of the 20th century by clinicians as an effective treatment when administered within an appropriate dosage range.

The paper summarizes results from a number of medical papers published mostly during the period from 1920-1940, though there are some from as early as 1902 and as late as the mid 1960s.

In a related effort seeking effective treatments for lymphoid tissue-related hearing loss, Samuel J. Crowe at the Johns Hopkins University developed treatments using radium implants that showed impressive results.

Based on extensive clinical experience, they concluded that the most efficient treatment of hearing impairment due to excessive lymphoid tissue is irradiation with radium or x-rays. So striking were the findings of this clinical research that they claimed there was the potential to reduce the number of deaf adults in the next generation by 50%.

The success led to numerous discussions about the best treatment regimes, the most effective doses, and the relationship of patient ages to doses and results. Not surprisingly, critics also asked questions about the side effects of ionizing radiation.

Why is Radiation Biology Funding Disappearing?

Atomic Insights has posted a number of articles about the health effects of low dose radiation that question the continuing use of the linear no-threshold dose response assumption. Those posts often attract passionate defenders of the status quo and occasionally stray into nastiness at the very idea of questioning the validity of regulatory standards based […]

Healthy doses of radiation

Doses of radiation that are lower than about 700 mGy/yr (see note below) are more likely to reduce cancer incidence and increase life span than to decrease it. In other words, moderate radiation doses are good for you in the same way as moderate exercise is good for you. The basis for this economy-altering assertion […]

Low dose radiation doesn’t cause cancer, it helps prevent it

Atomic bomb victims: dose versus leukemia cases

Dr. Jerry Cuttler recently published a letter to the editor of the Archives of Toxicology titled Leukemia incidence of 96,000 Hiroshima atomic bomb survivors is compelling evidence that the LNT model is wrong. Here are the concluding paragraphs of the letter. The continued application of the invalid linear dose–response model for cancer risk assessment raises […]

Don’t allow EPA to use “modernize” as euphemism for “tighten”

On February 3, 2014, The Hill Ballot Box blog published a call to action for nuclear energy and medical radiation therapy professionals titled EPA seeks to modernize nuclear standards. The EPA says it has not changed its radiation protection standards since the 1970s. Radiation health researchers would probably agree that there is a need to […]

CT Scans Save Lives

By Scientists for Accurate Radiation Information (SARI) We are writing to express our concerns with a January 30, 2014 article by Rita F. Redberg and Rebecca Smith-Bindman. The article is alarmingly titled, “We Are Giving Ourselves Cancer”, and is accompanied by a frightening cartoon that appears to be a doctor holding an X-ray film, and […]

Useful online book – Radiation and Health

The health effects of low level radiation are a continuing topic of conversation here and in many other places around the web. The Establishment view is known as the Linear No Threshold (LNT) assumption. Using that model, which was first applied to radiation standards development in 1956, every dose is assumed to impart risk to […]

Muller influenced the BEAR to adopt the Linear No Threshold (LNT) assumption in 1956

Hermann Muller, the 1946 Nobel Prize winner in Physiology and Medicine, insisted that there was no threshold of risk from ionizing radiation. His opinion has had a long lasting influence on standards for radiation dose. He was wrong. History is complicated. Influential people often impose their will with long-lasting results. The stories can be difficult […]

Realistic dose limits and better predictive models will help Fukushima recovery

World Nuclear News published an article titled Consistency required for Fukushima return that mentions several topics worth increased discussion. It mentions the report recently completed by the IAEA that complimented Japan on its efforts to decontaminate areas that were affected by the Fukushima Daiichi nuclear power station radioactive material releases. Then it went on to […]

Scientists for Accurate Radiation Information – Terrific reference site

There is a new group that you need to know about – Scientists for Accurate Radiation Information. Unlike another well known group that uses the word “scientists” in its title, the member list for this group includes a majority of people who actually have credentials and perform real, peer-reviewed research in the field in which […]

As High As Relatively Safe (AHARS) – Sensible radiation standards

Ionizing radiation is a known, studied and understood phenomenon to which the Precautionary Principle no longer applies. It is time to shift the paradigm that governs radiation exposure limits to a sensible standard of “As High As Relatively Safe” (AHARS). Aside: I’m crediting Dr. Wade Allison with the etymology of the term – AHARS. I […]
