Mediterranean diet as the ideal model for preventing non-alcoholic fatty liver disease (NAFLD)

The prevalence of nonalcoholic fatty liver disease (NAFLD) has dramatically increased in the 2–3 last decades and it represents the most frequent global cause of liver disease, affecting 25% to 45% of adults in most studies (1). The worldwide elevation in the population rates of NAFLD has come in parallel with rising unprecedented pandemics of obesity and diabetes. There is no specific medication for NAFLD and dietary/lifestyle modifications are the main foundations for the treatment of NAFLD. They are also very likely to be effective for its primary prevention. In this context, a dietary pattern that meets most requirements to become the ideal model for the prevention of NAFLD is the traditional Mediterranean diet (2). In addition to the potential for preventing NAFLD, the Mediterranean diet has sufficiently demonstrated its great ability to improve cardiovascular health. The accrual of prospective and well conducted studies showing cardiovascular benefits associated with better adherence to a high-quality food pattern is superior for the traditional Mediterranean food pattern than for any other dietary pattern (3)

Fijación activa y perforación ventricular: ¿una nueva entidad?

First, a new active fixation lead was implanted in the interventricular septum; the old lead was then extracted with a Cook stylet. The patient’s clinical course was satisfactory and there were no procedure-related complications. In conclusion, within the battery of diagnostic tests available to investigate suspected cardiac perforation, computed angiotomography of the chest is a highly useful complementary technique for the management of this complication

Incidental computed tomography diagnosis of a rare triad consisting of absence of coronary sinus, persistent left superior vena cava, and scimitar syndrome

We report a case of an unusual congenital triad consisting of absence of coronary sinus, persistent left superior vena cava and scimitar syndrome incidentally found in a CT-scan performed on a female complaining of exertional dyspnea

Radiologic features of small pulmonary nodules detected in initially negative screening CT examinations: a step towards personalized screening strategies?

Results of the National Lung Screening Trial (NLST) have invigorated the discussion around performing lung cancer screening using low-dose computed tomography (LDCT) of the chest. The NLST trial demonstrated a clear benefit of LDCT screening in reducing lung cancer and all-cause mortality, by showing reduced lung cancer mortality in high-risk individuals by about 20%, and allcause mortality by 6.7%, compared to a control group of subjects receiving chest radiographs

Preliminary Experience With the Use of Electromagnetic Navigation for the Diagnosis of Peripheral Pulmonary Nodules and Enlarged Mediastinal Lymph Nodes

Electromagnetic navigation is a new technique that can be used with bronchoscopy to obtain samples of small peripheral nodular lesions and enlarged mediastinal lymph nodes. It is very versatile in that it enables both transbronchial biopsies and fine-needle aspiration to be performed. We describe 2 cases in which navigation with the superDimension/ Bronchus system combined with traditional diagnostic techniques facilitated a definitive diagnosis by bronchoscopy. Electromagnetic navigation can obviate the need for more invasive diagnostic procedures such as surgery, thus saving time and money and avoiding complications

Incidental dual source computed tomography imaging of ductal aortic coarctation, left subclavian artery stenosis and bicuspid aortic valve in a patient admitted for atypical chest pain

A case of incidental ductal aortic coarctation with left subclavian artery stenosis at the origin, severely calcified and stenotic bicuspid aortic valve, and normal coronary arteries demonstrated by single breath hold dual source computed tomography angiography in a 46-year-old man admitted for acute chest pain is presented

Giant left atrial thrombus 17 years after orthotopic heart transplantation

We present the case of a 66-year-old woman who underwent orthotopic heart transplantation 17 years earlier for dilated cardiomyopathy. After 7 years allograft coronary vasculopathy developed requiring coronary artery angioplasty. In year 15 postoperatively she experienced congestive heart failure and she became symptomatic requiring diuretics and digoxin treatment. In year 16 postoperatively a routine coronary computed tomography (CT) angiography study revealed a giant thrombus in the left atrium. The patient had had no thromboembolicrelated symptoms. Anticoagulation therapy was introduced and the patient has not presented any thromboembolic-related complication. As the symptoms of cardiac insufficiency worsened we decided to evaluate the patient for re-transplantation

Coronariografía por tomografía computarizada de doble fuente

La tomografía computarizada multicorte (TCMC) permite estudiar las arterias coronarias de forma no invasiva. A pesar de la elevada resolución espacial y temporal de los equipos de sesenta y cuatro cortes (TCMC- 64) esta técnica no se encuentra exenta de limitaciones. La tomografía computarizada de doble fuente (TCDF) permite estudiar las arterias coronarias con gran calidad diagnóstica en todos los sujetos independien- temente de su frecuencia cardiaca sin necesidad, por tanto, de emplear betabloqueantes. En este trabajo se describen los estudios por TCDF de tres pacientes con elevada frecuencia cardiaca y gran variabilidad del ritmo. Se demuestra la utilidad de esta técnica para obtener estudios de excelente calidad diagnóstica en casos en que la coronariografía por TCMC-64 convencional presenta limitaciones. INGLÉS: Multidetector computed tomography (MDCT) has been demonstrated to be a very useful technique to non-invasively study coronary arteries. Despite the high spatial and temporal resolution of 64-slice MDCT scanners, this technique has several limitations. Dual-source computed tomography (DSCT) allows to study coronary arteries with excellent diagnostic quality in all subjects independent of the heart rate, thus avoiding the use of beta-blockers. In this article DSCT studies from three subjects with elevated heart rate and irregular heart rhythm are described. Usefulness of this technique to obtain studies of excellent quality in cases in which conventional 64-row-MDCT might present limitations is emphasized
