Haha speaking of femur fractures... fellow Sgt. on my SAR team is also a sound tech for a theater company. Right before opening night of their last production he told them all "I hope you all get bilateral femur fractures!!!"

There was a long moment of utter confusion before one of the actors remembered what a femur is.

if your elderly male pt has no leg hair, ask him about his cardiac history.

if your pt has a yellow rim around the iris, ask him about his high cholesterol.

No sh*t, really? Can you provide a source for that, that seems pretty cool. (PS- I don't think this was taught during my Basic course under assessments)

-Hence femur fx's hurt like a biatch and can cause some nasty internal bleeders (needing surgery!)
I was just thinking of quoting that and saying the same thing but you beat me to it!

No. I can't. But ask it and you get an answer nearly everytime that verifies it. It may be d/t diabetes or thyroid, but most often you'll find that the pt has had a bypass or something else. Either way, it will give you a hint of some medical Hx, especially if the pt is unable to answer your questions (Uncx, poor historians, etc) and you're into your secondary exam.

As for the ring around the iris, well, that's only useful if they aren't taking meds for high cholesterol already and c/o chest pain.

We have differnent things to say with my tech crew...Fly its smash a finger (hurts like no other!) runners its break an ankle, sound break and ear drum and for my fellow light techs its break a finger. :D

Lol actors. Just finished a play Saturday night and had to strike the set. I had to take a number of drills away from actors so I could get the screw out because they were stripping their 2 bit. Lol

Probably everyone knows these, but *shrug*

Clubbing of the fingers]Finger Clubbing is seen in association with many diseases, including Lung Ca, TB, chronic hypoxia, and others.

Splinter hemorrhages (thin reddish brown lines under the nails) are linked to bacterial endocarditis.

Gingival Hyperplasiais frequently associated with anti-seizure medicines (although NOT SPECIFIC!), can be associated with Calcium channel blockers and cyclosporine use.

Actors and striking sets, the technical aspect at least, is just a bad idea! I did tech (sound!). Give them costumes, not scenery or lights or anything with electricity or power tools.

Here's another fact, albeit not as exciting- I know...

Your foot is the distance between your wrist and elbow (I'm pretty sure...)

I keep reading it over and I don't see anything about thumbs.

Anosmia is the medical term for the inability to smell. It can be congenital or caused by brain injury, toxin exposure, nasal polyps, misuse of certain vasoconstrictive nasal sprays, drug use, esthesioneuroblastoma or a variety of other diseases.

Parosmia is a disorder in which a person incorrectly perceives present odors. For example, there will be roses in front of them, but they'll smell vomit. The false smell is usually something unpleasant.

I remember reading somewhere that drastic ridging and changes in fingernails is symptomatic of some condition. Saw a pt the other day who had this and it brought it up. Can't remember what it was, but this gal's nail beds were really, really gnarly for about the bottom 1/8" of her nail.
