measures best adapted for its relief. The condition may be produced either by an obstruction at the pylorus to the expulsion of the gastric contents, or by morbid changes in the muscular walls of the stomach without pyloric obstruction. Stenosis of the pylorus is most commonly due to cancer, but may also be produced by simple fibrous stricture, or by the cicatricial contraction resulting from t...

Figure 1: A CT scan 2 years (A) and 14 years (B) after the initial aortic repair. It shows the enlarged prosthesis diameter of 42 mm (black dotted arrows), which has remained stable over time. Compared with the original dimension, the cross-sectional area of the prosthesis increased by 96%, and the prosthesis wall tension by 40%. Figure 2: Reconstructed three-dimensional angiography demonstrati...

OBJECTIVE Systemic emboli related to atrial thrombi are a well known complication of percutaneous balloon dilatation of the mitral valve. The presence of left atrial thrombi therefore, is believed to be a contraindication to balloon dilatation. The purpose of this study was to determine the frequency of left atrial thrombi in patients referred for balloon dilatation of the mitral valve, the add...

BACKGROUND Balloon dilatation of the pulmonary valve remains controversial as a palliative procedure in tetralogy of Fallot. AIMS To determine the clinical outcome, growth of the pulmonary vascular tree and findings at surgery of balloon dilatation of the pulmonary valve performed as a palliation in infants with tetralogy of Fallot. METHODS AND RESULTS Thirty-three severely cyanosed infants...

The notion of a dilatation structure stemmed out from my efforts to understand basic results in sub-Riemannian geometry, especially the last section of the paper by Belläıche [2] and the intrinsic point of view of Gromov [5]. In these papers, as in other articles devoted to sub-Riemannian geometry, fundamental results admiting an intrinsic formulation were proved using differential geometry too...

HYPOTHESIS Resection of the gallbladder together with the dilated bile duct is the preferred treatment for pancreaticobiliary maljunction (PBM) with bile duct dilatation, whereas this treatment for PBM without bile duct dilatation is still controversial. DESIGN Retrospective study of 196 patients from January 1979 to November 2004. SETTING Two university hospitals. PATIENTS One hundred ni...

BACKGROUND To determine the incidence and prognosis of left ventricular dilatation and systolic dysfunction in 139 patients with hypertrophic cardiomyopathy during long term follow up. METHODS Left ventricular chamber dilatation and systolic dysfunction (both together referred to as left ventricular chamber dilatation) were determined echocardiographically. Chamber dilatation was defined as a...

Acute gastric dilatation is a potentially life-threatening entity that has been reported in patients with some acute infections like pneumonia and staphylococcal bacteremia. We describe a case of acute gastric dilatation presenting atypically in a 65-year-old diabetic with Salmonella diarrhoea. By the fourth day of hospital admission the patient's abdomen was distended in the absence of pain, n...

We consider the quasiconformal dilatation of projective transformations of the real projective plane. For non-affine transformations, the contour lines of dilatation form a hyperbolic pencil of circles, and these are the only circles that are mapped to circles. We apply this result to analyze the dilatation of the circumcircle preserving piecewise projective interpolation between discretely con...
