Vertebral osteopenia due to bone marrow hyperplasia during interferon-alpha and ribavirin therapy for chronic hepatitis C.

We report the magnetic resonance imaging of a severe, but fully reversible, vertebral osteopenia, due to bone marrow hyperplasia, occurring in a patient with chronic hepatitis C treated with the interferon-alpha/ribavirin combination.

Is the persistence of isolated GH deficiency in adulthood predicted by anatomical hypothalamic-pituitary alterations?

The aim of this study was to verify the persistence in adulthood of GH deficiency diagnosed in childhood and treated with hGH in childhood and to study whether anatomical hypothalamic-pituitary alterations evaluated by magnetic resonance (MR) imaging could predict it. To this goal, in six GHD adults (3 males and 3 females aged 17.2-24.

MRI diagnosis of intramedullary metastases from extra-CNS tumors.

The purpose of this study was to evaluate the topography, morphology and contrast enhancement of the intramedullary metastases (IM) from extra-CNS neoplasms. We report the results of a multicenter retrospective study on 18 patients with 26 IM examined with a 0.5T MR imaging system; intravenous injection of Gd-DTPA was performed in all cases.

[Magnetic resonance in the study of patients of short stature of the hypothalamo-hypophyseal origin. Report on 29 cases].

Although growth hormone (GH) deficiency is a very common cause of short stature, many cases are still diagnosed as idiopathic. Magnetic Resonance Imaging (MRI), more clearly than CT, reveals the anatomy of the hypothalamic-hypophyseal region and of the possible alterations (pituitary hypoplasia, interruption of the stalk) causing hormonal deficit. Twenty-nine patients with short stature underwent MRI examinations of the hypothalamic-pituitary region to assess the significance of the correlation between hormonal test and MR patterns.

Double blind randomized study using oral or injectable bromocriptine in patients with hyperprolactinaemia.

Objective: A new long-acting injectable form of bromocriptine has become available for long-term treatment of hyperprolactinaemic patients. The objective of this study was to compare efficacy and tolerability of injectable and oral forms of bromocriptine.

Design: A double-blind randomized study.
