Bowel and mesenteric injury: evaluation with emergency abdominal US.

PURPOSE: To assess emergency ultrasonography (US) for detection of bowel and mesenteric injury from blunt trauma. MATERIALS AND METHODS: For 3 years, prospective data on all patients undergoing emergency US were recorded. Patients with bowel and mesenteric injury were identified, and physical examination, laboratory, computed tomographic (CT), and intraoperative findings were compared with prospective data. RESULTS: From January 1995 to January 1998, emergency US was performed in 1,686 patients; 71 patients had bowel and mesenteric injury. Forty-one examinations were true-positive (i.e., with free fluid), and 30 were false-negative. Twenty-five of the 41 patients with true-positive US results had concomitant injuries that may have accounted for the free fluid, including liver, spleen, pancreas, gallbladder, kidney, and/or bladder injuries. The remaining 16 patients had isolated bowel and mesenteric injury. Bowel and mesenteric damage was identified intraoperatively in 70 patients. Twenty-nine of 30 patients with false-negative US examinations had abdominal tenderness. Sixteen patients with false-negative US results had bowel and mesenteric injury that was detected 12 or more hours after initial scanning. CONCLUSION: Free fluid in the abdomen is not detected in the majority of patients with isolated bowel and mesenteric injury. For clinical suspicion of bowel and mesenteric injury, observation, serial physical abdominal examination, and CT may be helpful in diagnosing this condition.

An STS-based radiation hybrid map of the human genome.

We have constructed a physical map of the human genome by using a panel of 83 whole genome radiation hybrids (the Stanford G3 panel) in conjunction with 10,478 sequence-tagged sites (STSs) derived from random genomic DNA sequences, previously mapped genetic markers, and expressed sequences. Of these STSs, 5049 are framework markers that fall into 1766 high-confidence bins. An additional 945 STSs are indistinguishable in their map location from one or more of the framework markers. These 5994 mapped STSs have an average spacing of 500 kb. An additional 4484 STSs are positioned with respect to the framework markers. Comparison of the orders of markers on this map with orders derived from independent meiotic and YAC STS-content maps indicates that the error rate in defining high-confidence bins is < 5%. Analysis of 322 random cDNAs indicates that the map covers the vast majority of the human genome. This STS-based radiation hybrid map of the human genome brings us one step closer to the goal of a physical map containing 30,000 unique ordered landmarks with an average marker spacing of 100 kb.

A gene map of the human genome.

The human genome is thought to harbor 50,000 to 100,000 genes, of which about half have been sampled to date in the form of expressed sequence tags. An international consortium was organized to develop and map gene-based sequence tagged site markers on a set of two radiation hybrid panels and a yeast artificial chromosome library. More than 16,000 human genes have been mapped relative to a framework map that contains about 1000 polymorphic genetic markers. The gene map unifies the existing genetic and physical maps with the nucleotide and protein sequence databases in a fashion that should speed the discovery of genes underlying inherited human disease. The integrated resource is available through a site on the World Wide Web at http://www.ncbi.nlm.nih.gov/SCIENCE96/.
