P729PD-1/PD-L1 axis contributes to infarct size in ST elevation myocardial infarction
2014
Programmed death-1 (PD-1) and Programmed death-1 ligand (PD-L1) regulate immune response. Previous studies associate an immune deregulation in ST-elevation myocardial infarction STEMI. We recruited 100 patients with a first STEMI treated with reperfusion. In all patients PD-1 and PD-L1 expression was studied 24 h post-reperfusion in peripheral blood mononuclear cells (PBMCs), by means of flow cytometry and molecular biology. PD-1 and PD-L1 expression was serially analyzed in the first 20 patients before reperfusion and 24h, 96h and 30 days afterwards. Results were compared with 30 age- and sex-matched controls. Cardiac Magnetic Resonance was used to quantify infarct size 1-week after infarc…
Three-dimensional transesophageal echocardiography in the guide of cardiac mass biopsy
2017
Cardiac tumors are rare. Cardiovascular imaging is more important in the differential diagnosis of cardiac masses but no current noninvasive diagnostic tool has the ability to absolutely diagnose cardiac tumors. In effect cardiac biopsy remains the gold standard in the differential diagnosis. In our case we show the advantages of three-dimensional (3D) transesophageal echocardiography as a guide for cardiac biopsy. We believe that 3D TEE is ready to be used in the guide of cardiac mass biopsy. Once interventionalists become confident with 3D imaging, this technique should be used routinely during these procedures.

Left Renal Vein Anatomical Anomalies: Radiological and Surgical Implications
1998
Objective: To emphasize the incidence and clinical, diagnostic and surgical implications of left renal vein developmental anomalies. Design: Retrospective analysis of case notes. Setting: Clinical Anatomy Department and Surgery Department, Faculty of Medicine, University of Valencia, Spain. Patients, participants: Standard radiological examinations (CT scan) performed on 745 patients; surgical findings at operation in 128 patients with aorto-iliac atherosclerotic disease, and 72 donor cadavers for transplantation. Main outcome measures: Incidence of left renal vein anomalies (retro-aortic left renal vein and peri-aortic renal venous collar), based on radiological (CT scan) and surgical obse…
Cerebrovascular Brainstem Diseases with Isolated Cranial Nerve Palsies
2002
There is a significant number of individual patients with cranial nerve palsies as the sole manifestation of MRI- and, less frequently, CT-documented small brainstem infarctions or hemorrhages. The 3rd and 6th nerves are most commonly involved and, less frequently, the 4th, 5th, 7th, and 8th nerves. An intra-axial basis for such lesions may be underestimated if the diagnosis is based solely on MRI. The electrophysiologic abnormalities indicating brainstem lesions may be independent of MRI-documented morphological lesions. This paper reviews the literature on cerebrovascular brainstem diseases manifesting as isolated cranial nerve palsies. It supports the concept that small pontine and mesen…

Ectasia and Aneurysm of the Right Coronary Artery Resulting From a Shunt to the Coronary Sinus
1998
A 65-year-old woman presented with a systolic-diastolic murmur. Further MRI investigations as well as angiography revealed an arteriovenous shunt to the coronary sinus via an enlarged right coronary artery (Figure 1A⇓ and 1B⇓). The distal part of this coronary artery was transformed to a large coronary aneurysm of such extent that the left atrium was compressed …
Solitary Myofibroma of the Bladder Trigone in a 3-Month-Old Patient: First Case Report
2016
Visceral solitary myofibromas are uncommon in childhood. We report a case of a solitary asymptomatic visceral myofibroma of the bladder trigone occurring in a 3-month-old boy. Once malignancies were ruled out by cystoscopy, radical excision was performed in order to avoid any potential impairment of bladder dynamic. Postoperative course was uneventful and patient was discharged on day 3 after surgery. After 36 months of follow-up, the patient is toilet-trained and remains well; bladder function is normal.
P-Wave Indices: Derivation of Reference Values from the Framingham Heart Study
2010
P wave indices constitute an intermediate, phenotype reflecting the impact of ischemic, metabolic and inflammatory insults on atrial electrophysiology and morphology. Measured from the surface electrocardiogram (ECG), they reflect dimensions of atrial depolarization and are modified by conditions that alter atrial conduction, atrial refractoriness, or may result in a proarrhythmic substrate. The P wave indices of duration and dispersion have most commonly been measured. An array of studies have utilized these P wave indices to distinguish subjects with diverse cardiovascular and non-cardiovascular conditions and diseases from healthy reference groups.(1) Computerized software has more recen…
