Since their approval, the direct oral anticoagulants have been widely used in the management of venous thromboembolism, for stroke and systemic embolism prevention in non valvular atrial fibrillation, and in venous thromboembolism prophylaxis after surgical hip or knee replacement. Because they are easy to use, with oral fixed doses and no biological monitoring need, they are more and more prescribed. New indications are rising in cancer associated thrombosis in France beyond the 6 first months of treatment, and to prevent cardiovascular events after an acute coronary syndrome, or in stable coronary or peripheral arterial disease in Europe. The efficacity and safety of direct oral anticoagulants in frail patients or in unusual pathological contexts are not entirely known, but further data are coming and will probably bring new answers.

Diabetes frequently occurs during corticosteroid treatment, sometimes necessitating urgent therapeutic management, with insulin for example. Corticosteroids induce insulin resistance in the liver, adipocytes and skeletal muscle, and have direct deleterious effects on insulin secretion. The development of insulin resistance during corticosteroid treatment, and the insufficient adaptation of insulin secretion, are key elements in the pathophysiology of corticosteroid-induced diabetes. ⋯ Pharmacological management of diabetes is needed in patients with blood glucose levels exceeding 2.16 g/l (12 mmol/l) and insulin therapy can be started when blood glucose levels are higher than 3.6 g/l (20 mmol/l) with clinical symptoms of diabetes. Insulin can then be replaced with oral hypoglycemic compounds when both blood glucose levels and corticosteroid dose have decreased. Patient education is essential, particularly for the management of hypoglycemia when corticosteroids are withdrawn or their dose tapered.

Adenopathies are a frequent cause of recourse in internal medicine. When histological analysis reveals the presence of granuloma, multiple infectious or non-infectious etiologies are considered. If diagnoses of lymphoma, sarcoidosis or tuberculosis are easily mentioned, tularemia should also be considered in the differential diagnosis. ⋯ The association of fever, night sweats, altered general state and mediastinal adenopathies should be considered as a diagnosis of tularemia. Ganglionic biopsy, combined with molecular biology techniques and serology, can confirm the diagnosis.

Case Reports
[An hereditary hemorrhagic telangiectasia of late revealed by a cerebral venous thrombosis: A case report].
Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant disease characterized by the triad of nose bleeding, telangiectasia and familial heredity. ⋯ This is the first case described of cerebral venous thrombosis treated with rivaroxaban revealing an HHT.
