1) Hyperhidrosis Prevalence and Demographical Characteristics in Dermatology Outpatients in Shanghai and Vancouver 2) Physiology of sweat gland function: The roles of sweating and sweat composition in human health 3) Hyperhidrosis and Its Impact on Those Living With It

1. a) The average human has 2-5 million sweat glands or 150-340 glands per sq. cm.

2. c) Defective sweat glands can secrete sweat beneath the surface of the skin (as opposed to the surface). As a result, the sweat is held beneath the surface of the skin and stimulates the inflammatory process involved in the development of atopic dermatitis

8. d) Iron. The other elements, copper, sodium, and calcium, are also found in sweat but were not identified by the I.O.C. as possibly being deficient in athletes.

9. b) 21 and 27%. In fact, another study demonstrated that individuals with severe HH had a rate of social anxiety disorder of 47% vs 14% in those without HH.

4. c) True, individuals with psoriasis have a 3.5-fold greater prevalence of AHH than those without the condition.

3. d) Hyperhidrosis is most prevalent in individuals less than 30 years of age. In fact, this group is 2.5 and 6.4 times more likely to develop HH than those aged 30-60 years and over 60 years, respectively

7. c) Fluoride is not present in sweat

6. c) Acetylcholine is the neurotransmitter that binds to sweat gland cell surface proteins called muscarinic receptors. This results in a cascade of cellular events that eventually moves sweat into the sweat gland ducts via tiny cellular channels called aquaporin-5.

5. a) While males are 20% more likely to develop HH, they are also more likely to have PHH, whereas women are most likely to have AHH. Women are more likely to develop late onset HH, that is, HH past the age of 30.

10. e) Moist skin predisposed individuals with HH to all of these skin surface conditions. Bacteria and fungi thrive in moist environments. For example, individuals with HH are 3.5 times more likely to develop athlete's foot.
