[Pseudotumoral calcinosis of the wrist compressing the radial nerve in systemic sclerosis].

Background: Pseudotumoral calcinosis, a rare complication of systemic scleroderma, is characterized by the presence in extra-articular tissue, but rarely intra-articular tissue, of large masses made up of hydroxyapatite crystals.

Patients And Methods: We report an original case of intra- and extra-articular pseudotumoral calcinosis of the wrist diagnosed in a patient followed for mild systemic scleroderma. The calcinosis was revealed in a highly unusual way via ductal syndrome secondary to compression of the radial nerve in the wrist.

Interventions to improve functioning, participation, and quality of life in children with visual impairment: a systematic review.

Visual impairment in childhood often has life-long implications. To aim for the highest levels of functioning, participation, and quality of life and to ensure children's well-being, children should be entitled to the most effective rehabilitation programs. We review evidence for the effectiveness of rehabilitation interventions for children with visual impairment to improve skills and behavior, thereby improving participation and quality of life as an ultimate goal.

[Thrombo-haemorrhagic disease-related hypoprothrombinemia-lupus anticoagulant syndrome revealing a light chains multiple myeloma].

Thrombosis and hemorrhage are two opposing manifestations of multiple myeloma. These hemostatic disorders are present in less than 12% of patients at diagnosis and involve various pathophysiological mechanisms. We report the case of a 39-year-old patient with multiple myeloma revealed by the association of a hemorrhagic syndrome and deep vein thrombosis related to a hypoprothrombinemia-anticoagulant lupus syndrome.

[Pyoderma gangrenosum following hematopoietic stem cell transplantation].
