Prosector
Generally, the risks to prosectors are low. Cadavers used for teaching purposes are embalmed before they are encountered by a prosector and students. Embalming fluid usually contains formaldehyde, phenol, Dettol, and glycerine which disinfect and kill pathogens within the cadaver. With exposure to embalming fluid, tissues and bodily fluids, such as blood, become fixed. Prosectors and students working with embalmed cadavers must always wear protective gloves, however this is more for protection against the harsh chemicals used in embalming such as formaldehyde and dettol which can cause moderate to severe skin irritation.
Hemorrhoid
While many topical agents and suppositories are available for the treatment of hemorrhoids, little evidence supports their use. Steroid-containing agents should not be used for more than 14 days, as they may cause thinning of the skin. Most agents include a combination of active ingredients. These may include a barrier cream such as petroleum jelly or zinc oxide, an analgesic agent such as lidocaine, and a vasoconstrictor such as epinephrine. Some contain Balsam of Peru to which certain people may be allergic.
