Comments on assignment 3

I think you have done a very good job.

The proposed sentence reads well. I made some minor changes:

The term actinic keratosis can be literally understood as a disorder (-osis) of epidermal keratinocytes that is induced by UV light exposure (actin-).

My only suggestion would be to briefly comment on other resources that you have looked at to address this issue. One strategy to reduce bias would be finding another credible resource that agree with or have similar information to the one that you are using. (Although they may not be easy to find).

Assignment #2
In the group discussion with our tutor, one of the points for potential improvement that we identified was the lack of information about the etymology of the term “actinic keratosis.” Although our article does a good job of introducing actinic keratosis in the initial paragraph, we thought it would be helpful to include a sentence or two about how the etymology relates to the etiology of the disease.

Search strategy
I first searched the PubMed database with the search terms “actinic keratosis etiology” (AND Boolean operation automatically applied between concepts), filtering by article type to review and systematic reviews, filtering by publication date to the past 5 years, and sorting by best match. Then, I searched the AccessMedicine database for relevant textbooks with the search terms “actinic keratosis AND etiology.”

Potential sources identified and considered

 * Siegel, J. A., Korgavkar, K., & Weinstock, M. A. (2017). Current perspective on actinic keratosis: a review. British Journal of Dermatology, 177(2), 350-358. Precancerous lesions and cutaneous carcinomas. In: Wolff K, Johnson R, Saavedra AP, Roh EK. eds.

Why the source was chosen
Out of the three main sources considered, the chapter from the Fitzpatrick’s Dermatology textbook (the chosen source) was the only one that had a comprehensive explanation of the etymology of the term “actinic keratosis.” Although the other two sources both discussed how the origin of “actinic” links to UV light or sun exposure, the chosen source also included a discussion of the etymology of “keratosis,” describing how it refers to a condition of the keratinized epithelium.

Three reasons why the source meets MEDRS criteria
First of all, the source is from a dermatology textbook, which would be considered a reputable secondary source. The source is also up-to-date as it was published in 2019 (within the recommended range of 5-7 years). Thirdly, the source is from an unbiased third-party publisher, McGraw-Hill Education.

How the source will be used
This source will be used for adding information about the etymological origin of the term “actinic keratosis” to the Actinic Keratosis Wikipedia article. It will be very useful for linking the etymology of the term to the etiology of the disease (i.e. sun exposure). This source will also be helpful for explaining why actinic keratosis is also referred to as solar keratosis.

Proposed changes
I propose to add the following sentence to the introductory paragraph of the article after the initial sentence:

The term actinic keratosis can be literally understood as a disorder (-osis) of overgrown horny (kerat-) skin cells (more commonly known as keratinocytes) that is induced by exposure to light rays (actin-).

Rationale for proposed changes
Adding this statement provides important information about the etymology of the term and would help to link the origin of the words to the etiology of the disorder (i.e. UV radiation). Without this change, there would be no explanation of the literal definition of "actinic keratosis," which is important for enhancing the readers' understanding of AK. Although the existing introductory sentence implicitly explains the meaning of "actinic" by stating that solar keratosis is synonymous with actinic keratosis, it does not provide an explanation of the meaning of the word "keratosis." The proposed change provides an explanation for the meaning of the word "keratosis" and does not assume that readers have a baseline knowledge of scientific terminology, which may be particularly helpful for readers who have not encountered these terms before.

The information behind the proposed change came from the 9th edition of Fitzpatrick's dermatology, a dermatology textbook accessed through the AccessMedicine database.

There were no areas of ambiguity or controversy within the proposed change. The etymological origins of the term are commonly agreed-upon and are well-established.

Critique of source
The source is relatively unbiased since it is a dermatology textbook -- which is considered a reputable secondary source -- released recently from a recognized publisher (McGraw-Hill Education). However, textbooks may still be susceptible to bias depending on the bias of the individual editors and contributors. Of the seven editors of this particular textbook, 5 are from American institutions and organizations, which might indicate a predominantly American influence in the content of the textbook. In addition, dermatology textbooks can be subject to racial bias, where cases and pictures demonstrate an under-representation of darker skin tones. However, any bias in the textbook is unlikely to feasibly impact the quality of the information drawn upon to make this specific change.
