An uncommon association: celiac disease and dermatomyositis in adults.

We describe the case of a patient with a two-year history of adult dermatomyositis (DM) who developed malabsorption revealing celiac disease. Our observation raises the question of an association between DM and celiac disease as part of a continuum, suggesting that celiac disease may be included within the spectrum of the gastrointestinal manifestations of DM and polymyositis (PM). From a practical point of view, our data indicate that the diagnosis of celiac disease should be suspected in PM/DM patients exhibiting malabsorption syndrome. Based on our findings, we further emphasize that an evaluation for celiac disease, including anti-gliadin antibodies, anti-endomysium antibody and tissue trans-glutaminase antibodies should be considered in PM/DM patients presenting with unusual and unexplained gastrointestinal features. This could lead to the early management of such patients, resulting in decreased morbidity (i.e., malnutrition and malignancy) related to misdiagnosed celiac disease.

[Proceedings: Prolactin adenoma revealed by gemellary? pregnancy after clomiphen therapy. Hypophysectomy during 5 th month of pregnancy (author's transl)].

A 25 year old woman had galactorrhea and secondary amenorrhea since her first pregnancy at 20 years. After several treatments with Clomiphene, menses reappeared for 2 months and she became pregnant. At admission, she was in her 4th pregnancy month and had headaches and bitemporal hemianopsia. Hypophysectomy was performed during 5th pregnancy month. Prolactin adenoma with hemorragic lesions was found. Parturition of normal twins occurred 8th month. Partial hypophyseal recovery took place for the following 2 years, but hyperprolactinemia reappeared too.

[Endothelin. A new class of vasoactive peptides].

Endothelin (ET) is a novel vasoactive peptide occurring in 3 isoforms (ET1, ET2, ET3) in humans. Derived from vascular endothelium cells, ET arises from a precursor peptide and exerts diverse actions through specific receptors. ET possess a wide spectrum of activities: a potent vasoconstrictor activity but also contraction of nonvascular smooth muscles (air-way, intestinal, urinary) or mitogenic actions, renal and endocrine effects. The physiological and/or physiopathological roles of endothelin is still unclear, but ET may play a part in the genesis of some vascular diseases as atherosclerosis, forms of hypertension or may be implicated in the pathogenesis of vasospasm.
