Congenital and Acquired Disorders of Ureteral Course.

A wide variety of entities can alter the course of the ureter in the abdomen and pelvis. These include conditions both intrinsic and extrinsic to the ureter leading to a number of different ureteral abnormalities including thickening, displacement, dilatation, etc. An understanding of ureteral pathology, as with any organ, first requires understanding of the normal anatomic appearance.

Rare case of entero-enteric intussusception caused by small bowel metastasis from a cardiac liposarcoma.

Primary cardiac liposarcoma is exceedingly rare and its metastatic potential varies based on the actual tumor subclass. Intestinal intussusception is also an uncommon cause of abdominal pain and bowel obstruction in adults and it usually generates at a malignant lead point in this age group. We report a case of a primary cardiac dedifferentiated liposarcoma in a pregnant woman causing small bowel seeding leading to bowel intussusception.

Duodenal diverticula: potential complications and common imaging pitfalls.

A duodenal diverticulum is a commonly encountered entity in gastrointestinal radiology with a wide variety of appearances. The purpose of this review is to describe the normal anatomy and embryology of the duodenum, discuss the differences between a true versus intraluminal duodenal diverticulum, and to highlight the normal appearance, potential complications, and imaging pitfalls of duodenal diverticula.

The efficacy of autologous platelet gel in pain control and blood loss in total knee arthroplasty. An analysis of the haemoglobin, narcotic requirement and range of motion.

Biological materials used to assist in haemostasis following total knee arthroplasty have been the subject of much recent research. Autologous platelet gel is a substance that is derived from platelet-rich plasma extracted from the patient's blood and centrifuged perioperatively, and is applied to exposed tissues, synovium and the lining of the wound at closure. Concentrating and applying these factors directly to the wound at the end of a total knee arthroplasty procedure may lead to more complete haemostasis, a reduction in perioperative blood loss, accelerated tissue repair and decreased postoperative pain.
