• Acoustic radiation force impulse imaging provides ultrasonic shear wave velocity measurements. • SWV measurements were higher in patients with inflammation or fibrosis than NAFLD. • ARFI differentiates NAFLD from NASH in patients with morbid obesity. • Results suggest that ARFI can detect NASH in asymptomatic morbidly obese patients.
Apprenticeship in laparoscopic appendectomy can be accomplished with gradual clinical training and without the need for resort to animal experimentation laboratories.
I have reviewed 280 patients with pT, tumours from a total of 786 with gastric carcinoma. Among 155 cancers that were confined to the mucosa, 69 (445 per cent) were of the diffuse type as opposed to 57 of 125 (45.6 per cent) that invaded the submucosa. The difference in the distribution of samples was not statistically significant Looking at these results, I do not think that the muscularis mucosae is a potential barrier to the invasion of the diffuse type of carcinoma into the submucosa.
'Damage control' in trauma surgerySir I read with great pleasure the Leading Article by Drs Hirshberg and Mattox from Houston, Texas (Br J Surg 1993; 80: 150-2). Perhaps
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
