A 21-year-old member asked:

isn't drinking cranberry juice to prevent urinary tract infection an old wives' tale?

No: Cranberry juice acidifys the urine which makes it harder for some bacteria to grow. There are also substances in cranberries thought to make it difficult for bacteria to get established.
Dr. George Klauber
Specializes in Pediatric Urology
Not a myth: Cranberries contain a chemical, proanthocyanidin, which interferes with the ability of bacteria, especially e.Coli (most common species of bacteria to cause urinary tract infections) from adhering to the bladder lining. Bacteria are thus flushed out urination and are unlikely to cause a uti. Excellent research article published in new england journal of medicine 3 or 4 years ago proving this.

A member asked:

Do colds lead to ear infections in children?

3 doctor answers5 doctors weighed in
Dr. Lisa Roberts
Pediatrics 23 years experience
Yes: Colds tend to precede the onset of an ear infection in children. This is because a cold causes fluid to develop in the middle ear, that at times may get infected by bacteria or viruses. Ways to decrease your baby's risk of ear infections are: 1) avoid smoke exposure, 2) try to limit pacifier use in those prone to ear infections, and 3) avoid having your baby drink milk laying down flat.
A member asked:

How can I help soothe pain from an ear infection?

Dr. Michael Amster
Specializes in Pediatrics
Motrin, mineral oil: Pain is due to stretching at the tympanic membrane, or ear drum. Prescription numbing agents can help, though gently warmed mineral oil dropped into the ear canal is very soothing. Holding a warm wash cloth to the ear increases the air pressure in the canal, helping push the ear drum back in, releasing the stretch. Of course Motrin and tylenol (acetaminophen) help relieve pain as well.

Depends: The choice of prophylaxis is based in part on where you're going and the resistance patterns of the malaria in the area. The cdc has a good website that discusses this issue based on region or country. When in doubt, see a travel medicine specialist.
