Diagnosis, treatment and maxillofacial rehabilitation in rhinocerebral mucormycosis patient: A case report and review of the literature.

Mucormycosis is an aggressive, rare and opportunistic infectious disease, with a high mortality rate. Etiologic agents are filamentous fungi, and infection among humans normally occurs through spore inhalation. A 61-year-old male individual, presenting left eye amaurosis, dark epistaxis, hyperalgesia and malodor underwent clinical examination, which detected ulcerative lesion and wide bone exposure in the hard palate and alveolar ridge.

Oral leishmaniasis: Report of two cases.

Leishmaniasis is a chronic inflammatory disease caused by several species of the parasite Leishmania that is transmitted by insects of the genus spp. or spp. This disease can affect skin, mucous membranes and viscera being classified as cutaneous, mucocutaneous and visceral leishmaniasis, depending on the spectrum of clinical manifestations.

Preparation, Antimicrobial Properties, and Cytotoxicity of Acrylic Resins Containing Poly(diallyldimethylammonium chloride).

Purpose: To design and analyze the biologic properties (antibacterial and antifungal, as well as cytotoxicity) of a dental biomaterial based on incorporation of the biocide poly(diallyldimethylammonium chloride) (PDADMAC) into the masses of self- and thermopolymerizable acrylic resins.

Materials And Methods: PDADMAC was diluted into tetrahydrofuran (4 wt%) and incorporated into self- and thermopolymerizable acrylic resins. PDADMAC inclusion was verified by measuring the contact angle with water droplets.

isolated from a pediatric patient with acute myeloid leukemia: The first case in humans.

This is the first report of the yeast (formerly ) causing disease in humans; its virulence and in vitro behavior against antifungals were also studied. The sample was isolated from biopsy fragments of disseminated lesions on the skin of a pediatric patient with acute myeloid leukemia. The studied virulence factors evidenced that the strain tested negative for secretion of the enzymes proteinase, phospholipase, and hemolysin.

Introduction: Acrylic resins are used in the preparation of facial prostheses and may be colonized by fungi. Here, we verified the antifungal efficacy of this material after surface treatment using poly (diallyldimethylammonium chloride).

Methods: Acrylic resin specimens with and without surface treatment were subjected to tests for fungistatic and fungicidal activities.
