More germs Planes desks and even kisses

Airplanes are so permeated with bacteria that it is truly a wonder that anyone survives a flight. Ill bet you thought it was the air in the cabin, but a recent story in USA Today says otherwise. "The real problems lie on the chair upholstery, the tray table, the armrests and the toilet handle."

What should germophobic passengers do? "First, they should travel with and use an alcohol-based hand sanitizer. They should also travel with a small pack of disinfectant wipes," said the microbiologist who did the study. "The first thing I do when I sit down is to wipe down the armrest and tray table because thats where my arms will be. You need to decontaminate where youll be spending your time and eating."

From MailOnline: "Millions of us spend our days slaving over a keyboard. But lurking between the keys, hidden on the mouse and nestled in your phone lies [sic] more than 10 million bacteria—400 times more than on the average toilet seat." [Despite what I reported in my last post, the toilet seat will remain the gold standard for comparing contamination levels until it is unseated.]

At least that is way fewer bacteria than the next study found.

"Every Kiss Begins With 80 Million Germs" headlines WebMD about a paper published in the journal Microbiome. WebMD story says, "In one experiment, the researchers gave 21 couples a probiotic drink containing bacteria before they kissed. Swab samples afterwards showed the transfer of those 80 million germs."

From the methods section of the paper: "One of the partners was invited to consume 50 ml of a probiotic yogurt drink containing L. rhamnosus GG, L. acidophilus LA5, and B. lactis BB12 [all non-pathogens]. After 10 seconds, saliva and tongue swabs were collected from this partner (donator) and after a second intimate ["full tongue contact and saliva exchange"] kiss of 10 seconds, saliva and tongue swabs were directly collected from the other partner (receiver)."

Saliva has some antibacterial properties. Maybe the researchers didnt wait long enough to test for bacteria after one of the partners drank the yogurt? People who have 80 million pathogenic bacteria in their mouths probably have bad breath and poor oral hygiene. I doubt they are indulging in 10 second tongue kissing.

And heres an excerpt from the conclusion. "This study indicates that a shared salivary microbiota requires a frequent and recent bacterial exchange and is most pronounced in couples with relatively high intimate kiss frequencies of at least nine intimate kisses per day [my emphasis] or in couples sampled no longer than 1.5 hours after the latest kiss."

Ten second kisses? Nine intimate kisses per day? Other than perhaps high school kids, who is kissing 9 times a day for 10 seconds at a time?

Bottom line? After eating yogurt, wait at least 90 minutes before tongue kissing someone.

Its that time of year again

Hopes are high; everyone is prepared; all the talk is over. The big day is finally here.

No, its not about the Super Bowl. Its about the American Board of Surgery In-Training Examination (ABSITE).

Every year at the end of January, all surgical residents take a five-hour, 250 question multiple-choice test. For many, it can be a watershed moment because their careers may be on the line.

I have written about the use of the ABSITE as a criterion for resident promotion. Whether you think it should be or not, it is used that way—sometimes as the only criterion. You can bet that in a few weeks, some residency programs will post notices saying they are looking for a categorical PGY-2 or 3 due to an "unexpected" vacancy for July 2015.

Another attending surgeon and I used to take in-house call the night before the examination so that all of the residents could take the test after a decent nights sleep.

Now the test may be given on different days so that the entire group does not have to take it at once.

One difficult situation I faced as a program director was when I had a good clinical resident who just could not do well on a multiple-choice examination. I had to decide whether keeping a resident who scored at the 10th percentile was worth the gamble. Scoring in the 10th percentile or less on a regular basis means that the resident has a good chance of failing the written board examination.

Of course, the very nature of percentiles is that 10% of those who take the test will finish in the 10th percentile or below. Also, the failure rate of the written board examination has hovered around 25% for many years.

The problem for programs is that the Residency Review Committee for Surgery mandates that 65% of a programs graduating residents must pass both parts of the board examination on the first attempt.

Of the many things I do not miss about practicing medicine during this turbulent era, the palpable level of anxiety surrounding the buildup to the exam and waiting for the dreaded results to come back rank high on the list.

I wish all residents who are taking the test the best of luck. I hope you were reading all along and not trying to cram a years worth of studying into the week before the test.

May you all score above the 50th percentile.
