The study of left ventricular diastolic function by Doppler echocardiography: the essential for the clinician

An abnormal diastolic function of left ventricle represents the main pathophysiological mechanism responsible for different clinical states such as restrictive cardiomyopathy, infiltrative myocardial disease and, specially, diastolic heart failure (also called heart failure with preserved systolic function), which is present in a large number of patients with a clinical picture of pulmonary congestion

Sigma's stenosis. Clinical, diagnostic and therapeutical problems

Sigma's stenosis represent a frequent pathology, but its very difficult to have a pre-operatory diagnosis about the nature of these stenosis, not withstanding the introduction of more sophisticated instruments of diagnosis. In this work we present 9 cases of sigma stenosis; some of these with a common etiology and other very interesting for their rare and unusual origins. The patients were underwent to a different timing of diagnosis and therapy based on clinical history and diagnostic hypotheses; our experiences demonstrate that the clinical intuition is really useful for a correct diagnosis in the patients with a sigma's stenosis and consequently, in order to plan the correct therapy

Usefulness of scintimammography with Tc-99m MIBI in clinical practice

Radiographic mammography (MM) is routinely used to diagnose breast cancer. MM has a number of well-known limitations, especially in cases of a dense or dysplastic breast. Scintimammography (SM) with Tc-99m MIBI has been successfully used as a useful complement to MM. The authors report a case of a 57-year-old woman with MM with tiny calcifications in the left breast, which were classified by the radiologist as probably benign lesions. SM with Tc-99m MIBI showed a focal area of increased uptake in the upper outer quadrant of the left breast. On the basis of SM results, an excisional biopsy was performed and pathologic examination revealed infiltrating ductal carcinoma
