UNLABELLED We evaluated whether spironolactone would improve cardiac sympathetic nerve activity and symptoms in patients with congestive heart failure (CHF). METHODS Thirty patients with CHF (left ventricular ejection fraction [LVEF] < 40%; mean, 30% +/- 9%) were treated with an angiotensin-converting enzyme inhibitor, a loop diuretic, and, in most cases, digoxin. Fifteen patients (group A) w...

Background: Mortalities resulting from firearms to the chest are still common worldwide. Although relatively uncommon compared other age groups, gunshots that occur in children fatal catastrophic events especially those penetrate thoracic cage. Air guns (pellets) less devastating than conventional firearms, but they can be particularly children. Case presentation: We present successful manageme...

The aim of the present study was to compare intensity-modulated radiation therapy (IMRT) and volumetric modulated arc therapy (VMAT) in irradiation of lung cancer. Plans of 14 patients were compared. The results demonstrated that in peripheral lung cancer, V5 (%) of the lung in partial-arc (PA)-VMAT was decreased compared with IMRT, single-arc (SA)-, and double partial-arc (2PA)-VMAT. V30 (%) o...

Background Chest tubes are used in every case of coronary artery bypass grafting (CABG) to evacuate shed blood from around the heart and lungs. This study was designed to assess the effective of Jackson-Pratt drain in compare with conventional chest drains after CABG. Materials and Methods This was a randomized controlled trial that conducted on 218 patients in Chamran hospital from February ...

Myocardial scintigraphy with meta-iodo-benzyl-guanidine (123I cMIBG) has been studied in Parkinson's disease (PD), especially in Asian countries, but not in Latin America. Most of these studies include individuals with PD associated to a defined dysautonomia. Our goal is to report the cardiac sympathetic neurotransmission in de novo Brazilian patients with sporadic PD, without clinically define...

The changes of the respiratory pressure within the esophagus, as well as within the posterior mediastinum, differ greatly in their various levels. They are best in the section between the heart and the diaphragm; they are moderate from the upper aperture of the thorax to above the tracheal bifurcation, and they are. very much reduced in the region of the bifurcation and the heart. In the latter...

Objectives. Both results of the odor identification and cardiac (123)I-metaiodobenzylguanidine accumulation have been investigated for their potential to enhance the detection of pathogenesis resembling that of Lewy body-related α-synucleinopathies in patients clinically diagnosed as having idiopathic REM sleep behavior disorder. Methods. We performed both the Odor Stick Identification Test for...

It is likely that a close association exists between findings obtained by two methods: dobutamine stress echocardiography and 123I-MIBG scintigraphy. Both of these methods are associated with beta-adrenergic receptor mechanisms. This study was conducted to demonstrate the relation between myocardial response to dobutamine stress and sympathetic nerve release of norepinephrine in the failing hea...

BACKGROUND Interleukin 1β (IL 1β) levels are associated with prognosis in heart failure. The cardiac adrenergic activity as assessed by metaiodobenzylguanidine (I123 MIBG) scintigraphy along with exercise parameters are important predictors of prognosis. The relationship between these variables is not fully established. OBJECTIVE To evaluate the association of IL 1β levels with exercise and I...
