Indeed, one can readily imagine a time in the not too distant future when all new cancer therapeutics will be routinely submitted

to such screens and the hypotheses generated used to guide clinical trial see more design.

“1. In the article entitled “Endoscopic treatment of postorthotopic liver transplantation anastomotic biliary strictures with maximal stent therapy (with video)” by James H. Tabibian et al (Gastrointest Endosc 2010;71:505-12), in Table 4, the study on the last line, Tabibian et al, contains information from the current study and should not refer to the study in reference 22. 2. The order of the authors in the letter to the editor entitled, “Endoscopic submucosal dissection for early gastric cancer: is it the best option for patients with contraindications to surgery?” (Gastrointest Endosc 2010;72:464) should be as follows: Romain Coriat, Said Farhat, Virginie Audard, Sarah Leblanc, Frédéric Prat, Stanislas Chaussade. 3. In the article entitled, “Efficacy

and safety of the new WallFlex enteral stent in palliative treatment of malignant gastric outlet obstruction (DUOFLEX study); a prospective multicenter study” by Jeanin E. van Hooft et al (Gastrointest Endosc 2009;69:1059-66), the authors stated that the World Health Organization performance score improved, which

“A Selleck PLX3397 Masitinib (AB1010) 37-year-old-woman from Sierra Leone presented with more than 5 years of cramping abdominal discomfort and mucus-containing watery stool. She had last traveled to Sierra Leone in 2001, and had no recent sick contacts, hospitalizations, or antibiotic use. She denied nausea, vomiting, fever, chills, or weight loss. Liver biochemical tests, serum amylase and lipase values, and multiple stool studies, including cultures, and examination for ova and parasites were unrevealing. Colonoscopy revealed findings of inflammation limited to the rectum suggestive of idiopathic proctitis (A) and biopsy specimens confirmed the presence of numerous ovoid ova with a lateral spine consistent with Schistosomiasis mansoni( B). She was treated with praziquantel (3 doses 20 mg kg given 6-8 hours apart with food). This resulted in complete resolution of her diarrhea. Another flexible sigmoidoscopy 6 weeks later ( C) revealed an endoscopically normal rectum; biopsies confirmed eradication of her parasitic infection. Commentary Schistosomes, named for their split body with a forked tail, are blood flukes that infect more than 200 million people worldwide. The species infecting this patient, S. mansoni, is endemic in regions of Africa, the Middle East, Puerto Rico, the Dominican Republic, and Central and South America. The colonic complications of S.
