Rehabilitation Research and Practice has retracted a 2012 review article on stiff big toes.
The article, “Therapeutic Management of the Hallux Rigidus,” came from a group in India. According to the abstract: Read the rest of this entry »
The paper, “Different bone mineral density in cervical and endometrial cancer,” came from a group of Soonchunhyang University and was published online late last year. It purported to look at the association between gynecologic cancers and bone mineral density: Read the rest of this entry »
Another busy week at Retraction Watch, beginning with a story we broke about faked HIV vaccine results that was picked up by the Des Moines Register and other outlets. Here’s what was happening elsewhere on the web: Read the rest of this entry »
In July, we reported on the unfortunate math of Harish Hosalkar, a San Diego orthopedic surgeon who was at the center of an institutional investigation into the integrity of his data, two lawsuits and three retractions.
At the time, we were waiting on the third retraction, in the journal Orthopedic Reviews. It has now arrived.
The article was titled “Open reduction and internal fixation of displaced clavicle fractures in adolescents,” and Hosalkar wrote it with Gaurav Parikh, James D. Bomar and Bernd Bittersohl. Read the rest of this entry »
The University of Tokyo panel investigating the work of a former professor there, Shigeaki Kato, has recommended the retraction of 43 of his group’s articles, according to a report in the Asahi Shimbun newspaper.
If the papers are indeed retracted, Kato, who already has at least five articles subject to an expression of concern and five retractions, would be fifth on the list of most retractions for a single author, by our unofficial tally. His fellow countryman, Yoshitaka Fujii, continues to hold the lead at what appears to be 183, followed by Joachim Boldt (~89), John Darsee (~83), and Diederik Stapel, at 53. [See note at end.]
The Asahi report quotes Kato — who has received some $20 million in government funding for his work — as acknowledging problems with the data in his studies: Read the rest of this entry »
Three retractions, two lawsuits, one institutional inquiry. That’s not the kind of math anyone likes to do — but it’s the tally for Harish Hosalkar, a San Diego surgeon specializing in pediatric orthopedics.
Hosalkar became embroiled in a messy affair after problems surfaced in data he had published while at Rady Children’s Hospital — a facility he left under a cloud of recriminations. More on that in a bit. Read the rest of this entry »
The journal Scoliosis has retracted a 2012 paper by a pair of German spine doctors over what the editors have called a less-than-fully declared conflict of interest involving one of the authors.
That should be relatively straigtforward – but it’s not quite. Turns out the article does include a disclosure, although perhaps the information it contains was incomplete.
The article, “Soft braces in the treatment of Adolescent Idiopathic Scoliosis (AIS) – Review of the literature and description of a new approach,” was written by Hans-Rudolf Weiss and Mario Werkmenn. Weiss, it seems, has something of a pedigree in the field. According to this website, he practices the “Schroth method” of recurvature, a technique pioneered by his grandmother, Katharina Schroth. From the site: Read the rest of this entry »
Well, we found — through relatively little effort — that the plagiarizees were themselves, shall we say, liberal in their use of material from other sources.
The retracted article was titled “Bone graft substitutes: What are the options?,” and it appeared in August 2012. One of the options, we guess, was to steal text.
Hip International has retracted a case study for duplication. (We apologize for the partial duplication of a headline for an earlier post about this journal, which told readers that “Similar cases will be referred to retractionwatch.”)
The article was titled “Chronic intoxication with cobalt following revision total hip arthroplasty,” and it appeared online ahead of print. Cobalt toxicity associated with metal-on-metal replacement hips has been raised as a potential adverse effect from the devices.
