Löfgren's syndrome is characterized by hiliar adenopathies, erythema nodosum and arthritis. It is a benign variant of sarcoidosis, common in the Mediterranean area. To describe the clinical characteristics, treatment and outcome of a series of patients diagnosed with Löfgren's syndrome. ⋯ Löfgren's syndrome is a benign form of sarcoidosis with a well defined clinical pattern. Biopsy is usually not required. Recurrence is scarce. The disease has a good prognosis.

For many years irritable bowel syndrome (IBS) and celiac disease (CD) have been considered 2 completely separate entities, with CD being clearly related to a permanent gluten intolerance and IBS having no relation with gluten ingestion. However IBS and CD symptoms may be indistinguishable, especially when diarrhea, bloating or abdominal pain predominate. In the last decade several studies have shown that the separation between CD and IBS is not so clear. ⋯ Gluten sensitivity is defined as the spectrum of morphological, immunological and functional abnormalities that respond to a gluten-free diet. This concept includes histological, immunological and clinical manifestations in the absence of evident morphological abnormalities. Therefore, it is mandatory to establish in a scientific way in which patients a gluten-free diet will be beneficial as well as when this is not justified.

Comparative Study
[Relevance of CYP2C19 2 regarding platelet reactivity in patients with acute coronary syndrome treated with clopidogrel].
Previous studies have shown that the metabolism of P2Y12 receptor blockers is influenced not only by CYP2C19 2 but also by PON1-Q192R alelles. We aimed to evaluate the impact of CYP2C19 2 and PON1-Q192R polymorphisms carriage in platelet reactivity and clinical outcome in patients with ischemic heart disease undergoing cardiac catheterization. ⋯ CYP2C19 2 polymorphism influenced moderately platelet reactivity but did not show an impact on clinical outcome in patients with acute coronary syndrome. Neither CYP2C19 17 nor PON1-Q192R polymorphisms showed an impact upon platelet reactivity or outcome.
