giant left atria are defined as those measuring larger than 8 cm and are typically found in patients who have rheumatic mitral valve disease with severe regurgitation. enlargement of the left atrium may create compression of the surrounding structures such as the esophagus, pulmonary veins, respiratory tract, lung, inferior vena cava, recurrent laryngeal nerve, and thoracic vertebrae and lead t...

introduction:  the aim of this study was to compare the preventive effects of corticosteroids and curcumin on subglottic stenosis in an animal model.  materials and methods: twenty-one male german shepherd dogs were used for this study. after standardized trauma to the subglottic area, the dogs were divided into three groups. group a received curcumin (450 mg/ day) for 15 days; group b received...

results compared to pre-op scores, pf, ss, and vas scores for back, buttock and leg pain had a significant mean decrease at 6, 12, 24 months post-op (p < 0.05). based on the zcq and vas scores, a success rate of 79% (27.34), 78% (30.38) and 74% (17.23) were achieved at six months, 12 months, and 24 months respectively. conclusions x-stop is a safe and effective treatment for nic that provides m...

myocardial fractional flow reserve (ffr) is a new index of the functional significance of intermediate coronary stenoses that is calculated from pressure measurements made during coronary arteriography. the aim of this study was to evaluate the correlation between non-hyperemic coronary pressure dicrotic notch and fractional flow reserve (ffr). a consecutive of 114 patients (73 men and 41 women...

         Combination of congenital esophageal atresia and subsequent hypertrophic pyloric stenosis is a rare condition which occurs in early infancy. The underlying etiology and pathophysiology of this association still remains unclear. In this paper we report a unique case of hypertrophic pyloric stenosis, for the first time, which occurred in an infant who underwent surgery for type I esophag...

The purpose of this study is to develop a mathematical model for studying the magnetic field effect on blood flow through an axially non-symmetric but radially symmetric atherosclerotic artery. Herschel-Bulkley equation has been taken to represent the non-Newtonian character of blood. The response of magnetic field, stenosis height, shape parameter on velocity, volumetric flow rate in stenotic ...

background: atrial fibrillation (af) is prevalent among cardiac patients; and as the risk of thromboembolism is high in this arrhythmia, discrimination of the effective risk factors in producing left atrial (la) thrombosis is clinically important. the molecular structure of lipoprotein(a) [lp(a)] is very similar to plasminogen , so it can be hypothesized that the high level of lp(a) is a compro...

a fifteen-year-old torkaman girl with turner's mosaic kariotype is presented. she has had congenital esophageal stenosis with severe dysphagia since birth and iron deficincy anemia in addition to other classical features of the syndrome. according to author's knowledge this is the first report of a new congenital structural gastrointestinal anomaly with this disease.

introduction: first branchial cleft anomalies manifest with duplication of the external auditory canal.   case report: this report features a rare case of microtia and congenital middle ear and canal cholesteatoma with first branchial fistula. external auditory canal stenosis was complicated by middle ear and external canal cholesteatoma, but branchial fistula, opening in the zygomatic root and...

objectives to evaluate predictive value of vessel specific coronary artery calcium (cac) score in predicting obstructive coronary artery disease. patients and methods in this diagnostic test study we evaluated patients with coronary computed tomography angiography (ccta) and cac score which had been referred to two referral radiology center in tehran, iran and finally we selected 2525 patients ...
