OK, we admit it, we just picked this one because of the title. But the method for removing objects from the rectum using a cluster of balloons is actually pretty inventive.

“Removal of a rectal foreign body (FB) has become increasingly common in the recent times. Nature of rectal FB is limited only by the imagination of the patient concerned. Many techniques have been described for removal and various theories have been put forward to explain the mechanics of the procedure. We report a case where a new technique had been employed.”

NCBI ROFL: Dung beetles use Uranus for orientation.

By ncbi rofl | April 2, 2013 12:00 pm

OK, fine. It’s actually the Milky Way (we couldn’t help ourselves). But really, either way, it’s pretty amazing that dung beetles use stars to pilot their way out of a pile of poop. And besides, any study that involves putting dung beetles in a planetarium is a winner in our books.

Dung beetles use the milky way for orientation.

“When the moon is absent from the night sky, stars remain as celestial visual cues. Nonetheless, only birds, seals, and humans are known to use stars for orientation. African ball-rolling dung beetles exploit the sun, the moon, and the celestial polarization pattern to move along straight paths, away from the intense competition at the dung pile. Read More

NCBI ROFL: Rectal foreign bodies: eggplant edition.

By ncbi rofl | March 29, 2013 12:00 pm

ER doctors have to deal with some crazy stuff, perhaps the funniest of which involves people with various objects stuck up their butts. From salami and oven mitts to “plastic or glass bottles, cucumbers, carrots, wooden, or rubber objects…bulb, tube light, axe handle, broomstick, vibrators, dildos, a turkey buster[sic], utensils, [and] Christmas ornaments,” the list is long and varied. However, we think “eggplant” ranks close to the top, if only for its sheer audacity. 

Management of rectal foreign bodies.

“Entrapped anorectal foreign bodies are being encountered more frequently in clinical practice. Although entrapped foreign bodies are most often related to sexual behavior, they can also result from ingestion or sexual assault.
METHODS:
Between 1999 and 2009, 15 patients with foreign bodies in the rectum were diagnosed and treated, at Izmir Training and Research Hospital, in Izmir. Information regarding the foreign body, clinical presentation, treatment strategies, and outcomes were documented. We retrospectively reviewed the medical records of these unusual patients.

NCBI ROFL: The wonders of koala poop revealed!

By ncbi rofl | March 21, 2013 12:00 pm

A lot of great things can come out of finding new ways to degrade stuff. Like reducing the number of plastic bags in our landfills, or producing fuels from plant matter. Nature has evolved many enzymes that do these sorts of things very efficiently–the trick is figuring out how to find the organisms that make them. These scientists decided to look in koala poop! Although it might seem like a smelly choice, it makes sense that there might be organisms in koala poop that eat the “leftover” fiber from all that eucalyptus. Om nom nom nom!

Fungi from koala (Phascolarctos cinereus) faeces exhibit a broad range of enzyme activities against recalcitrant substrates.

NCBI ROFL: What your poop looks like can tell you how long it’s been inside.

By ncbi rofl | February 25, 2013 12:00 pm

Editor’s note: after nearly 3 years of NCBI ROFL, we’ve decided to change things up a bit by beginning our posts with a few explanatory remarks. We hope that this isn’t off-putting to our loyal readers, and that it will make our posts more accessible to non-scientists. Enjoy!

Knowing how long it takes poop to travel through someone’s intestines can help doctors diagnose a number of health problems. But how can doctors tell what this “transit time” is? The scientists in this study investigated that question by having volunteers eat visible pellets and measuring how long it took them to come back out (perhaps you have conducted a similar observational study after eating corn). They then determined which characteristics of the poop correlated with “transit time”. Apparently, poop texture (“stool form”) is better than the weight (“output”) or frequency at predicting how long it’s been inside you.

Stool form scale as a useful guide to intestinal transit time.

“BACKGROUND: Stool form scales are a simple method of assessing intestinal transit rate but are not widely used in clinical practice or research, possibly because of the lack of evidence that they are responsive to changes in transit time. We set out to assess the responsiveness of the Bristol stool form scale to change in transit time. Read More

NCBI ROFL: When you’re allergic to your toilet seat.

By ncbi rofl | February 6, 2013 3:00 pm

A bum deal from wooden toilet seats: reemergence of allergic contact dermatitis.

“We report a case series of 5 patients who were found to have an allergic contact dermatitis (ACD) to their wooden toilet seats. The patients presented to our contact dermatitis clinic during a 5-year period from 2005 until 2010. In each case, there was a regional eczematous eruption localized to the buttocks and posterior upper thighs with an annular configuration that matched to the shape of the patients’ toilet seats Read More

NCBI ROFL: Fecal incontinence decreases sexual quality of life, but does not prevent sexual activity in women.

By ncbi rofl | February 1, 2013 3:00 pm

“BACKGROUND:
The impact of anal incontinence on women’s sexual function is poorly understood.
OBJECTIVE:
The aim of this study was to investigate the relationship between anal incontinence and sexual activity and functioning in women.
DESIGN:
This is a cross-sectional study.
SETTINGS:
This investigation was conducted in a community-based integrated health care delivery system.
PATIENTS:
Included were 2269 ethnically diverse women aged 40 to 80 years.
MAIN OUTCOME MEASURES:
Self-administered questionnaires assessed accidental leakage of gas (flatal incontinence) and fluid/mucus/stool (fecal incontinence) in the past 3 months. Additional questionnaires assessed sexual activity, desire and satisfaction, as well as specific sexual problems (difficulty with arousal, lubrication, orgasm, or pain). Multivariable logistic regression models compared sexual function in women with 1) isolated flatal incontinence, 2) fecal incontinence (with or without flatal incontinence), and 3) no fecal/flatal incontinence, controlling for potential confounders.

NCBI ROFL: Which makes you gassier: pinto beans, black-eyed peas, or baked beans?

By ncbi rofl | January 28, 2013 3:00 pm

Perceptions of flatulence from bean consumption among adults in 3 feeding studies.

“BACKGROUND:
Many consumers avoid eating beans because they believe legume consumption will cause excessive intestinal gas or flatulence. An increasing body of research and the 2010 Dietary Guidelines for Americans supports the benefits of a plant-based diet, and legumes specifically, in the reduction of chronic disease risks. The purpose of the current research was to investigate the perception of increased flatulence and gastrointestinal discomfort among participants who consumed a ½ cup of beans daily for 8 or 12 weeks.
