Annoying things about medical reporting



1. An article in Time magazine is headlined "It's Not You, Doctors Are Just Rude."

The first sentence of the article is " Doctors-in-training are in need of a dose of compassion."

It describes a paper from Johns Hopkins and the University of Maryland about intern communication behaviors. Interns were watched by trained observers.

Although interns were pretty good about touching patients and asking open-ended questions, they only introduce themselves 40% of the time and explained their roles only 37% of the time. They also sat down with patients just 9% the time.

Observations were made on 732 patient encounters, but only 29 first-year internal medicine trainees were involved.

The abstract did not explain whether these first-year interns had received any training in communication ("interpersonal skills and communication" is one of the 6 ACGMA core competencies), nor did it state at what point in their first year the study was done.

The headline of the piece in Time is a bit misleading since it suggests that all doctors are rude. Similarly, the first sentence of the article somehow brings in compassion.

The study was not about rudeness or compassion; rather it was about communication.

Maybe Johns Hopkins and the University of Maryland need to do a better job of teaching its interns, and maybe Time magazine needs to do a better job of reporting.

2. An article from a website called iMedicalApps gushes with excitement about the fact that Google Glass can be used by a surgeon to view continuous vital signs while operating.

It could be that Google Glass is going to revolutionize medical care, but I don't think it's going to be useful in the context of a surgeon looking at vital signs while she is operating.

You cannot concentrate on the operation and look at a Google Glass display of vital signs.

When I was operating, I was fully focused on the procedure. I depended on the anesthesiologist to alert me to any significant changes in the patient's vital signs.

If I wanted to know what the vital signs were, I simply asked the anesthesiologist. For me, that low-tech action was adequate.

3. Here's a headline from the Los Angeles Times. "Walk this way: Men slow down when sex is at stake."

This one is about a study from PLOS One that looked at 11 male and 11 female college students who walked around a track alone, with a significant other or with friends of the same or opposite sex. The study found that men walked significantly more slowly when they were paired with a female romantic partner compared to walking with another man or a woman who was simply a friend.

The authors concluded following: "Because the male carries the energetic burden by adjusting his pace (slowing down 7%), the female is spared the potentially increased caloric cost required to walk together."

This finding supports the idea that men are helping their romantic partners conserve energy and thus promote reproductive success. This is apparently a big issue in hunter-gatherer societies who walk long distances. It's not quite so clear why college students walking 400 meters would do the same thing. The authors speculated that it might be an evolutionary issue.

Regarding the article, a woman who follows me on Twitter said, "Not my hubby, tho we do have 2 kids."

Sorry LA Times, this one's not about sex, but I guess it makes for a better headline.

Analysis of a rather odd paper on cancer of the penis


Yesterday a Tweet by @DrVes caught my attention. It was a link to an abstract of a paper, published ahead of print in the Journal of Sexual Medicine, entitled “Sex with Animals (SWA): Behavioral Characteristics and Possible Association with Penile Cancer. A Multicenter Study.” Subjects were interviewed and completed questionnaires about their sexual experiences. The paper is from the Department of Pelvic Surgery, Hospital A.C. Camargo, São Paulo, Brazil and has 20 authors. I will leave the fascinating subject of multiple authors and what 20 people could have done to meaningfully contribute to the authorship of any paper for another time.

Instead, let’s focus on the findings of this study. I was unable to obtain a full text version of the paper but in this case, the abstract may be enough. The paper concerns the difference between men with and without penile cancer.

The abstract states, “SWA [sex with animals] was reported by 171 (34.8%) subjects, 44.9% of PC [penile cancer] patients and 31.6% of controls (P<0.008).” I know economic issues exist in Brazil and times may be bad. But ONE-THIRD of the nearly 500 men questioned HAD SEX WITH ANIMALS! And that represents just the ones who admitted it.

There is more. From the abstract: “SWA with a group of men was reported by 29.8% of subjects and SWA alone was reported by 70.2%. Several animals were used by 62% of subjects, and 38% always used the same animal. The frequency of SWA included single (14%), weekly or more (39.5%), and monthly episodes (15%).” It is not clear why the frequency numbers do not add up to 100%.

That SWA is a risk factor for penile cancer was confirmed on multivariate analysis.

Not to downplay the seriousness of penile cancer, but I think we have even bigger problems in Brazil. One, having lived exclusively in the USA, I may be naïve but one-third of men admitting to having sex with animals seems quite high to me. Two, what about the fact that 30% of the sexual activity with animals involved groups of men? Could it be that the animals are not always willing participants? Three, almost 40% had sex with animals on a “weekly or more” basis. Four, what about the integrity of these men? Only 38% were faithful to their animal partners.

I wish to thank the authors for sharing this with us. I look forward to their next study.

More Stuff Contaminated with Germs!

Squads of people are culturing every inanimate object in sight. Here’s the latest from a microbiologist at the University of Arizona as published in USA Today. [There is no link to the actual study.] It seems the worst thing you can touch (this week) is a gas pump, with 71% of them contaminated with “germs most associated with a high risk of illness.” Next in line are corner mailboxes, ATM buttons, escalator rails, parking meters, crosswalk buttons and vending machines.

An expert, Ashley Templin, 26, a hair stylist at the Ezelli Salon in Detroit, was quoted. She said that the thought of germs is such a problem for her that she doesn’t “use public rest rooms.” She does not say what she does when she has to urinate. Perhaps she never drinks beer or like many women, she holds it forever.

I have blogged before about the burgeoning culture of culturing everything. I continue to point out that no one has linked outbreaks of disease to gas pump handles, neckties, cell phones or the myriad other inanimate objects that are being cultured left and right. If this were truly a huge problem, we would all be continuously incapacitated by infectious diseases.

The article recommends handwashing, which of course is good advice.

What should we culture next? I suggest elevator buttons, movie theater seats, newsstands, car door handles, petting zoos and sewage treatment plants. Can you think of other things to culture?

Strokes, Sex, Headlines, Reportage


Today’s hot medical press release is about a paper describing factors which may trigger the rupturing of a cerebral aneurysm.

The study was performed using a questionnaire and included 250 subjects who had experienced a stroke related to a cerebral aneurysm. According to the article, published ahead of print in the journal Stroke, there are eight factors which can trigger the rupturing of a cerebral aneurysm.

In decreasing order of importance they are coffee drinking, vigorous exercise, nose blowing, sexual intercourse, straining to defecate, cola drinking, being startled and being angry.

There was some good news. Alcohol consumption mostly lowered the risk of stroke. Masturbation and using marijuana had no effect.

The study had some limitations such as those whose strokes left them with serious disabilities or death were unable to complete the questionnaire.

I have two comments.

Why is it that sexual intercourse, only the fourth most important factor in causing aneurysm rupture, was featured in the headlines of all of the organizations that printed the story—BBC News, Huffington Post, MSNBC, Eurekalert, Reuters to name but a few?

What the paper did not address was whether the risks were cumulative. For example, what if you had sexual intercourse while angry? Or even worse, what if you drank some coffee, then went to the bathroom to defecate [a common occurrence], while sitting on the toilet blew your nose and then were startled? Perfect storm?
