[Effectiveness and innocuousness of the association of calcium dobesilate, dexamethasone acetate and lidocaine versus prednisolone capronate with dibucaine clorohydrate in the treatment of hemorrhoids-].

The objective of the present study was to compare properties of two associations in the topical treatment of hemorrhoids. They were included 40 patient with diagnosis of internal hemorrhoids grade 1 or 2, which was indicated topic treatment after the realization of an interrogatory and anoscopy. The treatment received according to a randomized and double blind design: A = dobesilate of calcium with acetato of dexamethasone and lidocaine or B = Capronato of Prednisolone with Clorhidrato of dibucaina, applied twice a day.

[Portal hypertensive gastropathy: histologic and endoscopic correlation].

Paracoccidioidomycosis (PARA) affects only a minority of individuals, who have presumably been exposed to the causative fungus (Paracoccidioides brasiliensis). Neutrophils (PMNs) from patients with PARA show a significant and specific digestive deficiency phagocytosed P. brasiliensis in vitro.
