Using Magnetic Induction to Give a Cadaver’s Penis an Erection

Wednesday, April 3rd, 2019

Researchers used magnetic induction to get a rise out of, or into, a cadaver’s penis.

Details are in the study “Use of Magnetic Induction to Activate a ‘Touchless’ Shape Memory Alloy Implantable Penile Prosthesis,” Brian V. Le, Kevin T. McVary, Kevin McKenna, and Alberto Colombo, The Journal of Sexual Medicine, vol. 16, no. 4, April 2019, pp. 596-601.

The authors, at University of Wisconsin Madison. Loyola University Medical Center, Northwestern University, and Southern Illinois University, report:

We describe a novel physiologic penile prosthesis that uses shape memory alloy properties to mimic the transition between a flaccid and erect penis using magnetic induction instead of hydraulic pressure…. The device was then tested implanted in an animal tissue model and in cadaveric tissue. Testing consisted of placing the device deactivated in its more malleable and compressed state, then activating it using an external inducer wand…

A cadaver was implanted with a latex-covered penile prosthesis using a modified surgical technique through a penoscrotal approach. An adapter to accommodate standard Boston Scientific rear tip extenders was created for the model using 3-D printing technology and used to mimic the standard rear-tip extender used in contemporary IPPs and improved the device anchoring in the corpora cavernosa. The implanted penile prosthesis was activated by waving the inductor along the shaft of the cadaver’s penis…. The prosthesis reached an almost complete activation.

Brief versus Thong Hygiene in Obstetrics and Gynecology

Tuesday, April 2nd, 2019

Does thong underwear present heal hazards?  A new study addresses certain aspects of that general question. 

The study is “Brief versus Thong Hygiene in Obstetrics and Gynecology (B-THONG): A survey study,” Alyssa A. Hamlin, Jeanelle Sheeder, and Tyler M. Muffly, Obstestrics and Gynecology Research, vol., 131, May 2018, 108S ff. (Thanks to Gwinyai Masukume for bringing this to our attention.)

The authors, at the University of Colorado School of Medicine, Aurora and Denver Health and Hospital Authority, Denver, include data on:

Cleaning practices—

Wipe front to back

Wipe back to fr

They state this conclusion:

In this large cross-sectional study we found that oral sex was the only independent predictor of urinary tract infection and bacterial vaginosis, and that wearing noncotton crotch underwear was associated with yeast vaginitis. Wearing thong underwear was not associated with any urogenital infections. Medical providers should discuss sexual practices and underwear fabric, rather than style, with their patients when there is concern for urogenital infection.

“Journal to retract article from 2000 that plagiarized one from 1984”

Friday, February 22nd, 2019

In digging up material for a book, I ran across a pair of quasi-identical articles on an unusual topic. The articles were so similar that I sent word to our friends at the Retraction Watch web site, who dug into the history of those articles. Today, Retraction Watch published their report about those two reports:

Journal to retract article from 2000 that plagiarized one from 1984

When it comes to plagiarism, there is apparently no statute of limitations.

That’s one lesson one might take from this tale of two papers, one published in 1984 in the American Journal of Obstetrics and Gynecology (AJOG), and the other published in 2000 in the Medical Journal of The Islamic Republic of Iran (MJIRI). Both are titled “The use of breast stimulation to prevent postdate pregnancy.” …

In a note to us late last year, Marc Abrahams, the editor of the Annals of Improbable Research, flagged the apparent plagiarism. In January, we asked Hamid Baradaran, the editor of the MJIRI, if the journal was aware of the overlap. Baradaran, of the Iran University of Medical Sciences, said he’d follow up, and earlier this month he said that the journal had decided to retract the paper….

 

Nude Photos of College Students, for Research or Other Purposes

Tuesday, January 22nd, 2019

Many people like to study the nude bodies of other people. This study studied some of those students of student bodies:

Using the student body: College and university students as research subjects in the United States during the twentieth century,” Heather Munro Prescott, Journal of the History of Medicine and Allied Sciences, vol. 57, no. 1, 2002, pp. 3-38. (Thanks to Ben Wurgaft for bringing this to our attention.) The author explains:

Among the major results of these efforts were the infamous “posture pictures” collected at many elite men’s and women’s colleges around the country. The practice of photographing students in the nude started in the late nineteenth century, and continued well into the 19705. The original purpose of these photographs was to assess the physical health of students at admission, since many believed that poor posture was a sign of illness, particularly tuberculosis. Students were photographed every year to demonstrate the positive impact of physical education programs and other preventive health measures in college.

Physicians soon realized that these data could do more than demonstrate the effectiveness of physical education programs: they could also be used to show the physical superiority of young people from the white, native-born, upper-middle classes.
