The diagnostic value of sonography was assessed in 176 patients with jaundice who had a final diagnosis on the basis of surgery, autopsy, liver biopsy, endoscopic retrograde cholangiopancreatography, and serum tests positive for hepatitis A and B. Obstructive (n = 113) versus nonobstructive jaundice (n = 63) was diagnosed with a sensitivity of 91% and ...

THE INTRARENAL RESISTIVE INDEX AS A PATHOPHYSIOLOGICAL MARKER OF OBSTRUCTIVE UROPATHY
The Journal of Urology, 2001The intrarenal resistive index is a physiological parameter that indirectly reflects the degree of resistance in the intrarenal vasculature. Resistive index measurements have been advocated for the diagnostic evaluation of several renal pathologies, including obstructive uropathy. However, despite extensive research in this field during the last decade

Assessment of M-mode index of obstruction in patients with chronic obstructive pulmonary disease
The Scientific Journal of Al-Azhar Medical Faculty, Girls, 2020Background Diaphragm motion during forced expiration can be analyzed using M-mode ultrasound in an anterior subcostal approach. Maximal expiratory diaphragmatic excursion and forced expiratory diaphragmatic excursion in the first second physiologically mimic forced vital capacity (FVC) and forced expiratory volume in the first second (FEV1 ...

Obstructive sleep apnea syndrome and anthropometric obesity indexes
Sleep and Breathing, 2011The purpose of this study is to investigate whether the general body adiposity or regional adiposity was a risk factor in the evolution of obstructive sleep apnea syndrome (OSAS) by examining the relationships between the anthropometric obesity indexes such as waist (WC) and neck circumference index (NC), body mass index (BMI), and OSAS in Turkish ...

Aerosol penetrance: a sensitive index of peripheral airways obstruction
Journal of Applied Physiology, 1976Early injury of the small airways has been demonstrated in asymptomatic smokers. Ventilatory tests including the maximum midexpiratory flow rate and closing volume have been useful in clinical detection of small airways disease in symptomatic subjects. In the present study, airway “obstruction” was assessed aerodynamically by gamma camera measurements

Development of the Nasal Obstruction Disability Index (NODI)
European Archives of Oto-Rhino-LaryngologyThe aim of this study was to develop a new scale that assesses the subjective severity of nasal obstruction from functional and psychosocial perspectives, independent of etiology.A 27-question prototype scale evaluating nasal obstruction from a functional and psychosocial perspective was created by three expert otolaryngologists. This scale was applied

Renal Resistive Index in Experimental Partial and Complete Ureteral Obstruction
Investigative Radiology, 1992Recent clinical work suggests that the Doppler resistive index (RI) may be useful in distinguishing obstructive from nonobstructive hydronephrosis. We evaluated the usefulness of the RI in a rabbit model of hydronephrosis.Unilateral partial ureteral obstruction was produced in nine rabbits and complete obstruction in another nine. Three sham operations

Giornale italiano di cardiologia, 1979
An obstruction index to estimate the left ventricle outflow gradient from the echocardiogram in patients with obstructive cardiomyopathies is proposed. It is based on the measurements of the mean distance between septum and anterior mtral valve leaflet, the total time of narrowing and the time of minimal and maximal narrowing.
