@DavidElfstrom @skeila @WHO @ottawahealth It _is_ ridiculous.

Let's call a spade a spade.

They owe me a single peer-reviewed study of contaminated masks hurting someone.

@DavidElfstrom @skeila @WHO @ottawahealth Meanwhile the WHO committee is busy suggesting that we ought to tell HCW about the harms of N95 marks.

Conly et al. from summer.

@DavidElfstrom @skeila @WHO @ottawahealth Doing this on the fly. Here's their cite to the harm of respirators.

@DavidElfstrom @skeila @WHO @ottawahealth That's this.

@DavidElfstrom @skeila @WHO @ottawahealth That, in turn, is this. Check authors.

@DavidElfstrom @skeila @WHO @ottawahealth Here is what i see for HARM.

@DavidElfstrom @skeila @WHO @ottawahealth No wait, page 12 has this:

@DavidElfstrom @skeila @WHO @ottawahealth Although on the next page saying this:

@DavidElfstrom @skeila @WHO @ottawahealth Here are footnotes 39-44

This is certainly a miss.

@DavidElfstrom @skeila @WHO @ottawahealth 41. onlinelibrary.wiley.com/doi/full/10.11…

Studying skin reactions to PPE, including gloves, which were the big problem. It's a descriptive study, and therefore subjective.

pic 2: surgical masks no adverse reactions but N95s did, and the reactions are described in the pic.

@DavidElfstrom @skeila @WHO @ottawahealth 42. onlinelibrary.wiley.com/doi/full/10.11…

A report of two HCW that wore N95 masks for 3 months during SARS. This caused acne (which they had when younger) to flare up.

Both responded well to treatment, I am pleased to report.

No comment on whether they preferred no N95 during SARS.

This was an abstract, so the below pic is it. That's what's reported.

@DavidElfstrom @skeila @WHO @ottawahealth 44. journals.lww.com/dermatitis/Abs…

This is a case report of a doctor who had quite a serious reaction to formaldehyde in gown + N95 mask worn (used to preserve it).

So this more correctly should have been cited in support of not using gowns. Surgical masks may have this issue.
