A 19-year-old female asked:

why does hydrogen peroxide bubble when it is applied to a wound? just applied some to a cut, and it bubbled up and formed a crusty layer on it.

Hydrogen Peroxide: Blood & cells contain catalase. This enzyme is released in wounds. Catalase + hydrogen peroxide (H2O2) = water (H2O) + Oxygen (O2). The foam/ bubbles that arise are oxygen.

How do I care for a circumcision wound?

6 doctor answers13 doctors weighed in
Dr. Scott Katz
Pediatrics 26 years experience
Depends on type: There are 3 methods of circumcision. The first is the plastibell which leaves a plastic ring around the wound. No care is required other than keeping the area clean until the ring falls off in 5-7 days. The other 2 methods use a clamp and require gauze and ointment for the first week. If you feel there is evidence of infection or the ring does not fall off, your son should be reexamined.

Why did my doctor have to clamp and cut the cord during my delivery? Did I do something wrong?

No: This occurs when the umbilical cord is around the baby's neck and cannot be easily reduced or slipped over the baby's head prior to completion of delivery. There is nothing you did to cause this.
A 21-year-old member asked:

My dentist has recommended the biopsy of the premalignant lesion. What should I do?

Have the biopsy: A premalignant lesion is called that because lesions of that type have a high risk of degenerating into cancer. Once the 'premalignancy' becomes actual cancer it is a much bigger problem to fix. Often times the biopsy removes all the abnormal cells. This will decrease the risk of degeneration into cancer to zero. Waiting to see what happens risk losing lots of normal tissue to cure a cancer.

How can I cut down on alcohol?

2 doctor answers4 doctors weighed in
Dr. Jeff Blixt
Addiction Medicine 24 years experience
Cutting down is hard: For someone with alcohol dependence or alcoholism cutting down is likely harder than stopping completely and usually does not work well. People without drinking problems rarely would ever even think they need to cut down. Sometimes they may be able, but most recovering alcoholics will tell you they tried again and again and could not succeed, the craving was to strong after the first drink.
