Do Nosebleeds Cause Stool Blood Tests to Become Positive?

As a general rule, an ordinary nosebleed will not cause a screening stool blood test (hemoccult or guaiac) to come back positive.However, if the nosebleed is bad enough to consider going to the emergency room... and you are swallowing a lot of it... only than will it be likely that such stool tests will come back positive for blood.To be precise, such stool tests turn positive only if there's at least 2+ teaspoons of blood leaking into the digestive...

Why Would a Zenker's Diverticulum Recur After Surgical Treatment?

Zenker's diverticulum is an extremely rare disorder whereby a pouch develops in the throat leading to food and liquids getting caught causing symptoms of swallowing difficulties and food regurgitation. One of the best ways to address this rare condition is a procedure called endoscopic staple diverticulostomy (ESD).Unfortunately, with any Zenker's treatment including ESD, there is a small percentage (~10%) that the Zenker's diverticulum recurs typically...

Researchers published in the New England Journal of Medicine that removal of the tonsils and adenoids absolutely helps with sleep apnea in kids along with improvements in behavior, quality-of-life, overall well-being as well as significantly greater reduction in symptoms... but apparently putting off surgery does no significant harm as well from a purely cognitive perspective.464 children ages 5-9 years of age were randomly split into surgery...

Hospital Charges vs Surgeon Charges

Some of the most bitter complaints I get from patients are their hospital bills. Apparently, this complaint is not unique to me given numerous media articles about perceived outrageous hospital charges for seemingly simple procedures (article #1 and article #2).The healthcare system as it currently stands establishes 2 separate charges (surgeon and hospital) with any type of procedure performed in a hospital (even if not in an operating room). There...

Hearing Loss May be Caused by Aspirin, Tylenol, and NSAIDS

Researchers from Harvard and Vanderbilt reported that men who regularly take aspirin, tylenol, or NSAIDS (like ibuprofen) are at increased risk of hearing loss. This increased risk of hearing loss is significantly higher the longer the duration of regular use (defined as 2 or more times per week) and if regular use starts under the age of 50 years.For women, however, only tylenol and NSAIDS were found harmful to hearing (not aspirin).Indeed, the...

Woman Drinks Beer Through Her Ear

Now I am not sure if this woman is actually drinking beer through her right ear at a Czech beer festival as reported by Huffington Post, but is it anatomically even possible?Well the answer is that it IS theoretically possible though highly improbable.In order for this to occur, there must first be a hole in the eardrum. Given an eardrum hole, beer can be sucked up into the ear canal (1), through the hole in the eardrum (2), into the middle ear space...

What is the BEST Way to Disinfect a Toothbrush?

In my previous blog article, I discussed the debate over whether a toothbrush becomes "contaminated" leading to the practice of throwing them out after a strep throat infection. Although the answer is still ambiguous whether it helps or not, the fact that even NEW toothbrushes contain harmful bacteria brings even more confusion on what to do.Going on the assumption that bacteria on a toothbrush is harmful and if a new or old toothbrush contain...

Should Toothbrushes be Thrown Out After Strep Throat?

As with so many things with medicine, this question which sounds so straightforward unfortunately has no straightforward answer.After all, there have only been a few studies that have specifically looked to answer this question.And the answer is decidedly ambiguous as the few studies done so far either support or disprove this practice.Two studies have found no difference in recurrent infections whether one keeps using an old toothbrush or replaces...

Fecal Transplantation Administered Through the NOSE!
