3D endoanal ultrasound versus external phased array MRI in detection and evaluation of anal sphincteric lesions

The Egyptian Journal of Radiology and Nuclear Medicine
Background The anal sphincteric complex is formed by internal and external sphincters making two partially overlapping tubes around the anal canal. Anal sphincteric lesions represent a spectrum of entities with different patients’ presentations and ...

The dental plate on bichir pectoral fins: A unique dermal skeletal element bearing individual odontodes with tooth‐like replacement

Journal of Anatomy, EarlyView.
Pectoral fins of bichirs encompass the so‐called dental plates – unique dermal skeletal elements with individual odontodes identical to the oral teeth. Abstract The dermal skeleton appeared early in vertebrate evolution in the form of mineralized skin denticles composed of tooth‐like units—odontodes.

On the well-posedness of a mathematical model describing water-mud interaction

, 2012
In this paper we consider a mathematical model describing the two-phase interaction between water and mud in a water canal when the width of the canal is small compared to its depth.

Macroscopical and histological characterization of the perineal membrane and deep perineal pouch

Journal of Anatomy, EarlyView.
The existence of the deep transverse perineal muscle remains controversial. While the macroscopic appearance of the tissue in the deep perineal pouch differs between men and women, the differences in the histological composition of this fibromuscular plate is still unclear.

Spatiotemporal remodelling of the cloacal region determines the position of the anal opening in mouse embryos

Journal of Anatomy, EarlyView.
In E13.25 mouse embryo, the urorectal septum consistently positioned on the dorsodistal side of the cloacal membrane. Through 3D reconstruction of the cloacal internal space, we revealed that the position of the anal opening is established prior to cloacal membrane rupture and is located at the junction between the hindgut lumen (blue) and an expanded ...

Correlation of the Anatomy of the Intersphincteric Anal Fistula with Sex: An Analysis through Anorectal Three-Dimensional Ultrasound

Journal of Coloproctology
Introduction Anal fistula surgery is often associated with continence disorders due to transection of the anal sphincter muscles. A comprehensive understanding of the anatomy of the anal canal and fistula can help prevent this outcome.
