I had these little things on my face very often -- they didn't icht or hurt. It seemed like milia, actually. Coincidentally, when I was diagnosed with celiac disease and started a gluten free diet, they disappeared. I don't think they're DH but they may be related to gluten, yes.
As for the second dermatitis, I never had -- but if they improved after removing gluten, good for you!
I don't know if someone already posted about this, but anyway, I also have DH (and I am celiac, diagnosed about 1 month ago by a skin biopsy) and found that topical vitamin B5 works wonders for me -- relieves itching, DH heals faster, prevents the appearance of dark spots and scars, with the bonus of not being an irritant agent. Since it acts as a natural anti-everything (anti-inflammatory, anti-allergic and so on), besides being a skin healer and protector, I think it makes sense... Here is an article about it.
Incidentally, Vitamin B5 is helping my skin to recover in general -- I always had super dry skin, with acne and red spots due to celiac disease. Once I removed gluten from my diet and started doing a "ritual" of vitamin B5 (nighttime moisturizing mask and body creams), I notice the difference in 1 week!
