[Neurological manifestations of vitamin B12 deficiency: a retrospective study of 26 cases].

Purpose: Neurological symptoms of B12 vitamin deficiency are polymorph. Causes are dominated by Biermer's disease and B12 vitamin non dissociation that is frequent in the elderly.

Methods: We realized a retrospective study during 11 years.

[Cholesterol crystal embolism].

Cholesterol crystal emboli are a serious complication of atheroma. The incidence of this syndrome appears to be much more common in patients in their sixties with severe atheromatous disease of the aorta (20 to 30% vs less than 5%). 80% of crystal embolism result from medical interventions (aortic or cardiac surgery, arterial invasive procedure of aorta, thrombolytic therapy).

[Takayasu's disease in Morocco. Report of 47 cases].

Purpose: Takayasu's disease is a chronic inflammatory arteritis involving large vessels in young women. We studied Moroccan patients to evaluate clinical, biological, radiological and evolution features of this disease in our country.

Methods: Forty-seven patients with Takayasu's arteritis were studied retrospectively between 1988 et 1999.

[Behçet disease. 162 cases].

We report 162 cases of Behçet's disease, seen at the Internal Medicine Unit of Ibn Sina Hospital at Rabat, between January 1983 and June 1996. This series concerned 124 men et 38 women, Moroccans, whose mean age at first hospitalization was 32 years, and mean age at disease onset was 26 years.

Tuberculosis of the sternoclavicular joint. Report of two cases.

The sternoclavicular joint accounts for only 1 to 2% of all cases of peripheral tuberculous arthritis and is more often infected by pyogenic organisms than by the tubercle bacillus. We report two cases of sternoclavicular joint tuberculosis, in a 38-year-old man and a 46-year-old woman without risk factors for immune deficiency. Swelling of the joint was the presenting manifestation.

[Association of pulmonary artery aneurysm, right heart thromboses and antiphospholipid antibodies in Behcet's disease].

Introduction: Cardiac thromboses are unusual in the course of Behçet's disease and are frequently associated with endomyocardial fibrosis of the right heart. Vascular pulmonary involvement with either pulmonary aneurysm or parenchyma alterations is also often observed. However, pathogenesis of thromboses occurring in the course of Behçet's disease is still unclear.

[Cardiac involvement in Behçet's disease. 12 cases].

Fifteen cardiac manifestations observed in 12 of a series of 196 patients with Behçet's disease are reported. In this retrospective study conducted in an internal medicine department, 5 cases of pericarditis and 4 cases of myocardial infarction were encountered. The other cardiac manifestations were observed only once.
