 32 month old female child admitted to the hospital for chief complains of productive caugh and irritability which had been progressively increased during the two weks despite the treatment. Ôn sonography:  large round 5 cm mass occupied the left side of the heart with infiltration to the adjacent lung. ÇT scan findings confirm the sonographic result. The mediastinal mass with infiltrati...
BACKGROUND The objective of the present study was to investigate the effect of cardiac resynchronization therapy (CRT) on cardiac autonomic function. METHODS AND RESULTS This prospective study included 45 consecutive patients with heart failure who received CRT devices with defibrillator and 20 age-matched, healthy control subjects. At baseline and 3 months and 6 months after CRT, we assessed...
Cardiac I-meta-iodobenzylguanidine (MIBG) uptake was measured in 11 patients with dementia with Lewy bodies (DLB), 10 patients with Alzheimer’s disease (AD), and 10 age matched control subjects. The severity of cognitive impairment and duration of symptoms in patients with DLB matched that in the patients with AD. The heart/mediastinum (H/M) ratio of MIBG uptake in the patients with AD was indi...
difficult to treat asthma is an asthma syndrome that brings in our mind other differentials. mediastinal masses are not common findings, but are important variables. bronchogenic cyst is a congenital anomaly of the foregut that is typically found in the mediastinum and diagnosed accidentally. we present a 4-year-old girl with allergic asthma that began at 8-months of age and finally a bronchoge...
this is an original study on the effect of a polyisobutylene – polydimethylsiloxane (pibpdms) block copolymer modifier used as an interfacial active agent on the dynamics behaviour of single newtonian drops suspended in a polyisobutylene (pib) newtonian matrix. the results were divided in two sections. the first part included the experiments carried out on the non-modified and 2% block cop...
objective vitamin e is a major lipid-soluble antioxidant. it has been demonstrated that vitamin e supplementation has a beneficial effect against coronary heart disease (chd). this study to investigate the effects of coronary risk factors on serum vitamin e status in patients with dyslipidaemia. materials and methods this tertiary care hospital; case - control study was comprised 237 dyslipidae...
Background: The 123I-metaiodobenzylguanidine heart-to-mediastinum ratios (HMRs) have been standardized between D-SPECT and Anger cameras in a small patient cohort using phantom-based conversion method. This study aimed to determine the validity of this method compare diagnostic performance two larger cohort.Methods: We retrospectively calculated HMRs from early late anterior-planar equivalent p...
BACKGROUND Assessment of cardiac innervation using single-photon emission computer tomography (SPECT) is less established than planar imaging, but may be more suitable for quantification. Therefore, a volumetric quantification of I-123 MIBG SPECT acquisitions was performed. Reproducibility, the effects of extra cardiac I-123 MIBG uptake and the relation with conventional planar indices were eva...
