Concomitant myocardial infarction and systemic embolism associated with thrombosis of the right coronary ostium: a case report.

Background: Sequential occurrences of acute ischaemic stroke in patients with acute myocardial infarction (MI) and vice versa have been reported, but not the simultaneous occurrence of both conditions. We report a case of simultaneous occurrence of MI and systemic embolism caused by a mechanism not reported to date.

Case Summary: A 52-year-old female patient presented with concurrent chest pain, right arm weakness, and dysphasia.

Effect of powder air polishing and ultrasonic scaling on the marginal and internal interface (tooth-veneer) of ceramic veneers: an in vitro study.

Objectives: This study investigated the influence of prophylactic treatments and thermocycling on the marginal and internal veneering interface (tooth-veneer) as well as on the surface texture of ceramic veneers.

Materials And Methods: A total of 32 extracted human premolars were restored with veneers made of lithium disilicate (LDS) or zirconia-reinforced lithium silicate (ZLS). An artificial aging of the specimens was conducted via five cycles of both thermocycling (5/55°C) and prophylactic treatment (powder air polishing or ultrasonic scaling).

CD19-targeting CAR T-cell therapy in patients with diffuse systemic sclerosis: a case series.

Background: CD19-targeting chimeric antigen receptor (CAR) T-cell therapy has shown remarkable outcomes in patients with systemic lupus erythematosus. The effects of CD19-targeting CAR T cells on organ manifestations in patients with systemic sclerosis have yet to be characterised. B cells have a central role in the pathogenesis of systemic sclerosis.
