CHAPTER 57 Disorders of the Umbilicus

Pediatric Surgery International, 2007

Umbilicus is considered a mirror of the abdomen in newborns. Despite its importance, the umbilicus has been stated in literature and textbooks as discrete subjects with many body systems, such as the urinary, digestive, and cardiovascular ones. This article aimed to address the basic knowledge of the umbilicus in relation to clinical disorders under one integrated topic to aid physicians and surgeons in assessing newborns and infants. The umbilicus appears as early as the fourth week of fetal life when the folding of the embryonic plate occurs. The umbilicus appears initially as a primitive umbilical ring on the ventral aspect of the body. The primitive umbilicus contains the connecting stalk, umbilical vessels, vitelline duct and vessels, allantois, and loop of the intestine. Changes occur to form the definitive cord, which contains three umbilical vessels, namely, " one vein and two arteries, " embedded in Wharton's jelly. After birth, the umbilical vessels inside the body obliterate and gradually form ligaments. Congenital disorders at the umbilicus include herniation, bleeding, and discharge of mucous, urine, or feces. Some of these disorders necessitate emergent surgical interference, whereas others may be managed conservatively. The umbilicus has many embryological remnants. Thus, the umbilicus is prone to various clinical disorders. Detecting these disorders as early as possible is essential to prevent or minimize possible complications.

Hernia of umbilical cord is a well-known entity which presents with herniation of small bowel into the proximal part of umbilical cord. It has very good prognosis after surgical repair. Occasionally, it can have distinct presentations and varied malformations at the umbilicus which have bearing on the course of treatment and final outcome. Herein, we describe various presentations and malformations associated with hernia of umbilical cord. Embryological extrapolation is attempted for the malformations at umbilicus.

Critical Indigenous Fish Philosophy , 2024

This course explores the emerging field of ‘Critical Indigenous Fish Philosophy’. Drawing on materials from Critical Indigenous Studies, Indigenous Science and Technology Studies, geography, physics, ecology, decolonizing movements, and other approaches, this course explores what fish have to teach us about law, governance, philosophy, art, and existence. •Comparative analysis of information about fish across diverse knowledge systems •Knowledge mobilization of this information in dynamic ways (narrative, art, policy-oriented materials) to convey the complexity of fish life and worlds •Explore diverse governance systems to better understand what is required to protect fishhabitats and fish communities •Appreciation for the diversity of global Indigenous and local practices and approachesemployed to protect fish •In honouring the territories this class takes place in, a significant amount of the materialcovered draws from Indigenous nations on the West Coast, as well as across the country
