Endoscopic stenting for gastroduodenal outlet obstruction of a malignant origin, real life experience in a single center.

Aim: to evaluate the safety and effectiveness of self-expandable metal stent placement for malignant gastric outlet obstruction (GOO).

Methods: a retrospective, analytic cohort study at a single, tertiary-care center.

Results: thirty-six patients that underwent stent placement for GOO of malignant origin were identified during the study period.

Serologic features of primary Sjögren's syndrome: clinical and prognostic correlation.

Sjögren's syndrome (SS) is a chronic inflammatory systemic autoimmune disease. The disease spectrum extends from sicca syndrome to systemic involvement and extraglandular manifestations, and SS may be associated with malignancies, especially non-Hodgkin's lymphoma. Patients with SS present a broad spectrum of serologic features.

Susac's syndrome: an update.

Susac's syndrome is an infrequent neurological disorder characterized by the clinical triad of encephalopathy, hearing loss, and branch retinal artery occlusions. Its pathophysiology is not entirely clear, although it is now thought that it is most probably an immune-mediated endotheliopathy that affects the microvasculature of the brain, retina, and inner ear. An early diagnosis is important as treatment can halt disease progression and prevent permanent disability.
