MRI is a Reliable Method for Measurement of Critical Shoulder Angle and Acromial Index.

 The objectives of this study are to compare absolute values of acromial index (AI) and critical shoulder angle (CSA) obtained in both radiographs and magnetic resonance image (MRI) of the shoulder; and to compare the interobserver and intra-observer agreement for AI and CSA values measured in these image modalities.  Patients who had medical indication of investigating shoulders conditions through radiographs and MRI were included. Images were taken to two fellowship-trained shoulder surgeons, which conducted measurements of AI and CSA in radiographs and in MRI.

Case Report: Composite pheochromocytoma with ganglioneuroma component: A report of three cases.

Composite pheochromocytoma (CP) is a very rare tumor originating from neural crest cells, predominantly composed of pheochromocytoma (PCC), a chromaffin cell tumor arising in adrenal medulla, and ganglioneuroma, a tumor derived from autonomic ganglion cells of the nervous system. Moreover, CP may be present in the hereditary syndromes of which pheochromocytoma is part. Literature offers scarce data on this subject, and particularly about its biological behavior, clinical evolution, and molecular profile.

Body self-image disturbances in women with prolactinoma.

Objective: To evaluate body dissatisfaction and distorted body self-image in women with prolactinoma.

Methods: Body dissatisfaction and distorted body self-image were evaluated in 80 women with prolactinoma. All patients were in menacme, 34% had normal body mass index (BMI), and 66% were overweight.

[Decreased bone mineral density in pre-menopause women with prolactinoma].

Unlabelled: Tumoral hyperprolactinemia and consequent hypogonadism have been associated with osteoporosis. Bone mineral density (BMD) was measured by dual-energy RX absorptiometry in 24 patients with prolactinoma (15 macro and 9 micro adenomas; age range = 18 to 49 years). Student unpaired t or Mann-Whitney tests were used to compare groups, and Spearman test studied correlations.

[IGF-1 plasma levels evaluation in prolactinoma].

Prolactinomas are the most frequent pituitary tumors and may co-secrete GH (growth hormone). IGF-1 (insulin-like growth factor-1) is the main responsible for GH actions and a parameter for the diagnosis of acromegaly. With the objective of identifying through a IGF-1 levels analysis, in the initial evaluation of prolactinoma patients, the existence of mixed tumors [GH and prolactin (PRL)], we studied 7 men and 27 women, aged between 19 and 72 years, confronting them with the results of basal and glucose stimulated (glucose tolerance test--GTT) GH levels, indicated when GH >0.

[Prolactinomas and bone mineral density in men].

Throughout the years evidence has been accumulated on the morbidity of hyperprolactinemia, particularly in terms of bone mineral density decrease. This complication of hyperprolactinemia affects both women and men. In this paper, we analyze aspects related to bone loss in men with hyperprolactinemia due to prolactinomas: prevalence, clinical relevance, physiopathology, diagnosis and the consequences of the treatment of hyperprolactinemia and hypogonadism on bone mineral density.

[Clinical and therapeutic aspects of prolactinoma in men].

Macroprolactinomas predominate in males in comparison to microprolactinomas, with greater trend to invasiveness than in females. The clinical treatment has been the first option to prolactinomas, in both macro and microadenomas, irrespective the sex. We compared clinical presentation, prolactin levels, neuroradiologic invasiveness and prolactinemia response of 23 men with prolactinomas subjected to clinical therapy (group 1) with 19 who went also through surgical and/or radiotherapeutic treatment (group 2).
