Oral shedding of CMV and HSV-1 in hematopoietic stem cell transplantation patients.

Objectives: To evaluate the oral shedding of herpesviruses in patients undergoing hematopoietic stem cell transplantation (HSCT) and correlate it with oral mucositis (OM).

Methods: Saliva samples were collected before the HSCT and on day D + 8. Multiplex Polymerse Chain Reaction (PCR) was performed to detect herpes simplex virus (HSV)-1 and HSV-2, Epstein-Barr virus (EBV), Cytomegalovirus (CMV), Variella-zoster virus (VZV), and human herpesvirus (HHV)-6, HHV-7, and HHV-8.

Efficacy of imidazolquinoline on treatment of condyloma acuminatum of the buccal mucosa.

The condylomata acuminata is a benign epithelial neoplasm induced by papillomavirus, and it is characterized by the proliferation of stratified squamous epithelial tissue that affects the anogenital and oral mucosa. It is considered to be a sexually transmitted disease and has a higher prevalence in individuals infected with human immunodeficiency virus. Various therapies have been used for the removal of lesions, such as cryotherapy, surgical laser and surgical excision, which are painful and scarring.

Application of two segmentation protocols during the processing of virtual images in rapid prototyping: ex vivo study with human dry mandibles.

Objectives: The aim of this study was to evaluate the accuracy of virtual three-dimensional (3D) reconstructions of human dry mandibles, produced from two segmentation protocols ("outline only" and "all-boundary lines").

Materials And Methods: Twenty virtual three-dimensional (3D) images were built from computed tomography exam (CT) of 10 dry mandibles, in which linear measurements between anatomical landmarks were obtained and compared to an error probability of 5 %.

Results: The results showed no statistically significant difference among the dry mandibles and the virtual 3D reconstructions produced from segmentation protocols tested (p = 0,24).
