A functional collagen adhesin gene, acm, in clinical isolates of Enterococcus faecium correlates with the recent success of this emerging nosocomial pathogen.

Enterococcus faecium recently evolved from a generally avirulent commensal into a multidrug-resistant health care-associated pathogen causing difficult-to-treat infections, but little is known about the factors responsible for this change. We previously showed that some E. faecium strains express a cell wall-anchored collagen adhesin, Acm. Here we analyzed 90 E. faecium isolates (99% acm(+)) and found that the Acm protein was detected predominantly in clinically derived isolates, while the acm gene was present as a transposon-interrupted pseudogene in 12 of 47 isolates of nonclinical origin. A highly significant association between clinical (versus fecal or food) origin and collagen adherence (P

Pancreatic adenocarcinoma in a patient with situs inversus: a case report of this rare coincidence.

BACKGROUND: Situs inversus (SI) is a relatively rare occurrence in patients with pancreatic adenocarcinoma. Pancreatic resection in these patients has rarely been described. CT scan imaging is a principle modality for detecting pancreatic cancer and its use in SI patients is seldom reported. CASE PRESENTATION: We report a 48 year old woman with SI who, despite normal CT scan 8 months earlier, presented with obstructive jaundice and a pancreatic head mass requiring a pancreaticoduodenectomy. The surgical pathology report demonstrated pancreatic adenocarcinoma. CONCLUSION: SI is a rare condition with concurrent pancreatic cancer being even rarer. Despite the rarity, pancreaticoduodenectomy in these patients for resectable lesions is safe as long as special consideration to the anatomy is taken. Additionally, radiographic imaging has significantly improved detection of early pancreatic cancer; however, there continues to be a need for improved detection of small neoplasms.

Anatomia in qua tota humani corporis fabrica... Amstelodami, Ioannes Ianssonius, 1617

A paper affixed to the rear free endpaper of the item states that is edition contains “fine reproductions of the Gemini plates.” “Thomas Geminus was a a pseudonym for Thomas Lambrit, an engraver and printer…shown as active from about 1540; he died in May 1562.” http://www.arsanatomica.lib.ed.ac.uk/geminus.html accessed 11/20/2012. Geminus (Lambrit) printed Compendiosa totius anatomiae delineation aere exarata in 1545 copied from Vesalius’ 1543, De humani corporis fabrica . (Wellcome Library catalog, accessed 11/20/2012.) This book is a 1617 reproduction of the engraved copperplates which Lambrit himself copied from the original woodblock prints of the Vesalius’ book. Because the illustrations were based on those in the Vesalius’ book, because the name Vesalius helped sell the book, because copyright laws were not in effect, and because photocopies and digital images were not available, the author of this book is given as Andreas Vesalius. (Vesalius may or may not have been pleased.)
