More than a quarter of NHS trusts in England have failed to meet one or more hygiene standards set by the Healthcare Commission. |
Of the 103 trusts (26% of the total of 391 trusts) that failed on at least one of three core hygiene standards in 2007-8, 40 had slipped back from better performance the previous year. |
The area where the greatest number of trusts struggled was in the decontamination of reusable medical devices. Seventy trusts failed to meet this standard. Thirty five trusts could not say that they had complied with standards on …An operator expansion formalism for nonlinear surface waves over variable depth |
The Hamiltonian formalism for surface waves associated with the method of Watson & West (1975) is extended to handle the case of spatially varying bottom depth. This description models moderately nonlinear waves over a wider range of scales than Boussinesq-type approximations. A pseudospectral simulation code has been ... |
PURPOSE |
To assess a new interpretation model combining kinetic pattern and morphologic characteristics using high-spatial-resolution MR imaging. |
MATERIALS AND METHODS |
Breast MR imaging was performed in 58 patients with 63 pathologically proved focal breast masses (49 malignant and 14 benign). MR imaging was performed on a 1.5-Tesla system using the volumetric interpolated breath-hold examination (VIBE) sequence. Morphological parameters were lesion shape, mass margin, rim enhancemen... |
RESULTS |
The most frequent types of lesion shape/margin in the malignant lesions were irregular (47%) and spiculated (43%), whereas 13 of the benign lesions had smooth or lobular margins (93%). The most frequent characteristics in breast cancers with lobulated configuration were washout pattern (80%), whereas 78% of the lobulat... |
CONCLUSION |
"Washout with enhancing septations" is thought be specific for carcinoma with a lobulated configuration (80%). A combination of morphological criteria (including lesion shape/margins, strongly high signal on T2-weighted images) and visual washout is useful for differentiating between benign and malignant lesions.Linear... |

The colon is a remarkable organ in that it manages the final products of digestion after nutrient assimilation, and packages it as waste to expel. The colon has the highest bacterial load of any organ, with commensal bacteria occupying a niche that prevents noncommensal organisms from expanding, and some bacteria produ... |
Fundamentally, the colon is 1 organ, but develops from 2 different embryonic areas of the primitive gut: the midgut, which gives rise to the small intestine through to the proximal two thirds of transverse colon, and the hindgut, which gives rise to the distal third of the transverse colon through the upper anal canal.... |
The development of neoplasia likewise differs by site within the colon. As we age, a left-to-right colon cancer shift ensues between the seventh and eighth decades of life.6 Females are more likely to develop proximal cancers whereas males develop more distal cancers,4 suggesting the possibility of hormonal influences ... |
Morphologic and genetic differences of colonic neoplasia are observed based on site within the colon. Laterally spreading tumors, a type of superficial “flat” spreading neoplasm, are commonly found in the right colon, and can be difficult to detect without enhanced endoscopic methods.11 These lesions are much more like... |
