The family name as socio-cultural feature and genetic metaphor: from concepts to methods.

A recent workshop entitled "The Family Name as Socio-Cultural Feature and Genetic Metaphor: From Concepts to Methods" was held in Paris in December 2010, sponsored by the French National Centre for Scientific Research (CNRS) and by the journal Human Biology. This workshop was intended to foster a debate on questions related to the family names and to compare different multidisciplinary approaches involving geneticists, historians, geographers, sociologists and social anthropologists. This collective paper presents a collection of selected communications.

Blunt injury to mesentery and small bowel: CT evaluation.

Helical CT now allows rapid acquisition of sections through the abdomen and pelvis with optimal vascular opacification and minimal motion artifact. Oral contrast may aid in the identification of subtle bowel and mesenteric injuries and does not have any significant deleterious effects. CT findings of extraluminal enteric contrast, active hemorrhage, or free intraperitoneal-retroperitoneal air allow accurate diagnosis of SBMI in the setting of blunt abdominal trauma. Mesenteric hematoma in association with bowel wall thickening or the presence of significant amounts of free fluid without solid organ injury is highly suspicious for SBMI requiring laparotomy. CT alone or in concert with DPL and physical examination is a valuable tool in the timely diagnosis and treatment of bowel and mesenteric injury caused by blunt trauma.
