Maximum phonation time in the pulmonary function assessment

Maximum phonation time in pre-school children.

UNLABELLED Past studies on the maximum phonation time (MPT) in children have shown different results in duration. This factor may reflect the neuromuscular and aerodynamic control of phonation in patients; such control might be used as an indicator of other evaluation methods on a qualitative and quantitative basis. AIM To verify measures of MPT and voice acoustic characteristics in 23 childr...

Maximum phonation time: variability and reliability.

The objective of the study was to determine maximum phonation time reliability as a function of the number of trials, days, and raters in dysphonic and control subjects. Two groups of adult subjects participated in this reliability study: a group of outpatients with functional or organic dysphonia versus a group of healthy control subjects matched by age and gender. Over a period of maximally 6...

Assessment of the maximum uptake time of 99mTc-DMSA in renal scintigraphy in rat

Introduction:The optimal imaging time of a radionuclide scintigraphy is the time at which the organ of interest has the maximum uptake of the injected radionuclide. This study was performed to investigate the maximum uptake time of 99mTc-DMSA in rat renal scan. Methods: Renal scintigraphy was performed with 3 mCi of 99mTc-DMSA. Planar ima...

Pulmonary function in ulcerative colitis

 Abstract Background: Pulmonary involvement in ulcerative colitis (UC) is thought to be rare. There is not a definite document about the question that "Is the lung a target organ in inflammatory bowel disease?" The aim of the present study is to compare lung function between cases with UC and healthy controls. This study will also be of interest about searching the outbreak of pulmonary functio...
