The Prevalence of Biphalangealism for Each Toe in the Turkish Population: An Epidemiologic Study.

BACKGROUND: Biphalangealism has been evaluated in many studies and has been shown as a common variant. Its frequency varies according to the populations. This epidemiological study aimed to determine the prevalence of biphalangealism for each toe in the Turkish population and compare it with other populations. METHODS: The local hospital radiological database was searched for all consecutive foot radiographs, obtained between 2014 and 2018. Anteroposterior (AP) and oblique radiographs obtained to evaluate trauma or foot pathologies were included. Two-phalangeal toes according to radiographical views were defined as biphalangeal and other three-phalangeal toes were defined as normal. RESULTS: A total of 2,881 radiographs of 2,710 adult patients met the incusion criteria. There were 1,558 (57.5%) female and 1,152 (42.5%) male patients. The cases were unilateral in 2,539 patients and bilateral in 171 patients. The overall prevalence of biphalangeal third toe was 0.29%, fourth toe was 1.29%, and fifth toe was 23.3%. CONCLUSIONS: The presence of pedal biphalangealism is a common variant and its frequency varies according to the populations. The exact cause is still unclear. Further studies are required to assess the clinical impact of biphalangealism.

YouTube English videos as a source of information on arm and shoulder exercise after breast cancer surgery.

PURPOSE: To examine the reliability, quality and content of YouTube videos on exercises that can be performed after breast cancer (BC) surgery. METHODS: Videos selected from YouTube using the search terms 'shoulder exercise and BC surgery', 'arm exercise and BC surgery' and 'physiotherapy/physical therapy and BC surgery' were categorised as useful or misleading by a surgeon and a physiotherapist. The videos were analysed using the 5-point DISCERN scale for reliability, the Global Quality Scale for quality and a 10-item scale for comprehensiveness. RESULTS: Of the 180 videos initially analysed, 82 were included in the study, and 42 (51.2%) were classified as having misleading information and 40(48.8%) as having useful information. The reliability, quality and content scores of the videos containing useful information were higher (p < 0.001). Most of the videos in the useful information group (80%) were uploaded by universities/professional organisations/physicians/physiotherapists, while the majority of those in the misleading information group (47.6%) were uploaded by websites providing independent healthcare information. CONCLUSION: YouTube can be an important instrument to protect patients from musculoskeletal system complications after BC treatment and improve existing complications. Universities, physicians and physiotherapists should be encouraged to prepare more videos containing full and accurate information on this subject.
