Although Zermelo-Fraenkel set theory (ZFC) is generally accepted as the appropriate foundation for modern mathematics, proof theorists have known for decades that virtually all mainstream mathematics can actually be formalized in much weaker systems which are essentially number-theoretic in nature.

Closed-system suctioning: why is the debate still open?

From mycobacteria to sarcoidosis--is the gate still open?

ciation between mycobacteria and sarcoidosis, and it has been hypothesized that sarcoidosis could be a separate manifestation of infection with mycobacteria. Therefore, most studies of a possible causal microoganism have focused on mycobacteria. Mycobacteria are ubiquitous all over the world with reservoirs in humans, animals, water and soil. Besides the usual forms, mycobacteria may exist in o...

[Acute cholecystitis: is it still justified to delay surgery?].

Urgent Carotid Surgery: Is It Still out of Debate?

Patients with symptomatic tight carotid stenosis have an increased short-time risk of stroke and an increased long-term risk of ischaemic vascular events compared with the general population. The aim of this study is to assess the safety, efficacy, and limitations of urgent CEA or CAS, in patients with carotid stenosis greater than 70% and clinically characterized by recurrent TIA or brain dama...
