Intrabolus pressure gradient identifies pathological constriction in the upper esophageal sphincter during flow [PDF]
American Journal of Physiology-Gastrointestinal and Liver Physiology, 2003 Propulsion of a bolus through the upper esophageal sphincter (UES) is driven by a pressure drop in the direction of flow against frictional resisting force. Basic mechanics suggest that the axial rate of drop in intrabolus pressure (IBP), i.e., the intrabolus pressure gradient (IBPG), should be locally sensitive to abnormal constriction.

Chronic constrictive pericarditis: Further consideration of the pathologic physiology of the disease
American Heart Journal, 1952Abstract 1. 1. The methods of catheterization of the heart and the pulmonary vessels make it practical, for the first time, to investigate the pressure and flow phenomena in the right side of the heart and in the pulmonary vascular system of patients with constrictive pericarditis. Six such patients have been studied by these methods. 2.

International Journal of Cardiology, 1990
We performed endomyocardial biopsy in six patients with constrictive pericarditis, revealing the presence of myocarditis and myocardial interstitial fibrosis in all regardless of the endocardial thickening. These findings suggest that the presence of endomyocardial involvement in the setting of restrictive heart disease should not be deemed specific ...

We report the pathological findings of hourglass-like fascicular constriction (HLFC) under optical and electron microscopy. A 24-year-old man with spontaneous posterior interosseous nerve palsy was treated by interfascicular neurolysis at 29 weeks after onset.

CHRONIC CONSTRICTIVE PERICARDITIS
Journal of the American Medical Association, 1938Chronic constrictive pericarditis is a term applied to the condition which results when fibrous thickening of the pericardium interferes mechanically with the normal movements of the heart and blood. Nineteen patients with an undoubted diagnosis of constrictive pericarditis have been observed by us in the Vanderbilt University Hospital in Nashville and

Clinics in Chest Medicine, 1993
This article reviews the histopathological findings in a variety of inflammatory bronchiolar diseases. The emphasis is on differentiating syndromes of idiopathic airflow limitation (constrictive bronchiolitis and diffuse panbronchiolitis) from cryptogenic organizing pneumonia (idiopathic bronchiolitis obliterans organizing pneumonia).

Pain, 1998
Tumor necrosis factor alpha (TNF) may be involved in the pathogenic mechanisms of neuropathic pain by affecting endothelial cells and by upregulation of receptor sensitivity in afferent nerve fibers. To test the hypothesis that TNF plays a role in the vascular changes and the pain-related behavior in an experimental painful neuropathy in rats produced ...

Abstract The pressure tracings obtained by right-heart catheterization are described in ten patients with constrictive pericarditis and three patients with acute pericardial effusion. The left-atrial and ventricular-pressure tracing of one of these is shown.

Morphodynamics and pathology of blood vessels II. Morphodynamic study of constriction of umbilical blood vessels and its application to coronary artery disease [PDF]
International Journal of Angiology, 1996 The morphodynamic changes of the umbilical artery from full distension to total occlusion within 45 seconds of delivery is very striking. On gross examination, the constricted artery shows a small, round, outer contour and reduced external diameter.
