The appearance of angiotensin receptor blockers (ARBs) amongst the therapeutic options in the treatment of cardiovascular diseases (CVDs) was a new milestone in the history of hypertension treatment. It further widened the range of possibilities for personalized therapy, especially for patients who cannot tolerate the use of angiotensin converting enzyme inhibitors (ACEIs).

Transvaginal ultrasound is the main reference technique in the evaluation of adnexal masses. Based on the Breast Imaging Reporting and Data System (BIRADS) classification Amor et al. suggested adapting this system to gynecologic ultrasound for the evaluation of adnexal masses: Gynecologic Imaging Reporting and Data System (GI-RADS) and based on recognition patterns and criteria recommended by the IOTA group.

Diagnosis of Porphyria Print E-mail

The porphyrias are disorders of heme synthesis, which has eight steps. Each type of porphyria involves a defect, either inherited or acquired, in a pathway enzyme. When the defect is physiologically significant, it results in overproduction of pathway precursors preceding the defective step which enter the circulation and are excreted into urine or bile. The diseases have been grouped as acute hepatic porphyrias and photocutaneous porphyrias. The acute porphyrias are due to hepatic overproduction of the porphyrin precursors, delta aminolevulinic acid and porphobilinogen, and the symptoms are caused by injury primarily to the nervous system. Cutaneous porphyria is due to overproduction of photosensitizing porphyrins by the liver or bone marrow, depending on the type of porphyria.

Thyroid Imaging Reporting and Data System (TI-RADS) Print E-mail

Thyroid nodules are a frequent finding on neck sonography. Most nodules are benign; therefore, many nodules are biopsied to identify the small number that are malignant or require surgery for a definitive diagnosis. In 2012, the ACR convened committees to (1) provide recommendations for reporting incidental thyroid nodules, (2) develop a set of standard terms (lexicon) for ultrasound reporting, and (3) propose a TI-RADS on the basis of the lexicon.
