Mycosis fungoides: reflectance confocal microscopy and its role in the diagnosis

Appl. cancer res; 38 (), 2018
Background: Mycosis fungoides (MF), a T-cell lymphoma, is the most common variant of primary cutaneous lymphomas. The discrete clinical aspect of the early patch-stage and an overlapping clinical presentation with other erythematosquamous skin diseases make the diagnosis of MF challenging. Histopathology...

Effect of sonic versus ultrasonic activation on aqueous solution penetration in root canal dentin

J. oral res. (Impresa); 7 (1), 2018
The aim of this study was to observe the penetration of an aqueous solution into the root canal dentin under sonic activation and ultrasonic activation. Materials and Method: this study consisted of experimental in vitro research. In order to achieve a closed system, the apex of 45 single-rooted teeth wa...

Comparative study of root resorption between two methods for accelerated orthodontic tooth movement

J. oral res. (Impresa); 7 (9), 2018
Objective: the aim of this study was to assess apical root resorption (RR) following the application of micro-osteoperforation (MOP) and piezocision (PzC) assisted orthodontics for the acceleration of tooth movement (TM). materials and methods: a total number of 16 patients seeking orthodontic therapy we...

Plasmocitoma: desafio diagnostico em paciente idosa com apresentação clínica atípica. relato de caso

INTRODUÇÃO E OBJETIVO: O plasmocitoma é uma proliferação neoplásica de um clone de plasmócitos que produzem imunoglobulina monoclonal. O plasmocitoma solitário ósseo é definido pela presença de um plasmocitoma na ausência de múltiplas lesões osteolíticas ou outros achados compatíveis com ...

Terapia de reemplazo renal continua en el paciente con oxigenación por membrana extracorpórea: consideraciones para la combinación de ambas terapias

Rev. méd. Chile; 146 (1), 2018
The presence of renal dysfunction is not unusual in patients with pulmonary or cardiac dysfunction who require rescue with extracorporeal membrane oxygenation (ECMO). The complexity, implicit in the implementation of both techniques, can be overwhelming. This review aims to explain the most important asp...

Positron emission tomography/magnetic resonance imaging (PET/MRI): An update and initial experience at HC-FMUSP

Summary The new technology of PET/MRI is a prototype of hybrid imaging, allowing for the combination of molecular data from PET scanning and morphofunctional information derived from MRI scanning. Recent advances regarding the technical aspects of this device, especially after the development of MRI-comp...

The T-loop in details

ABSTRACT Introduction: The T-loop as designed by Burstone is a space closure spring used in the rational application of orthodontic biomechanics. Despite the diversity of studies, there is still no consensus on the optimal parametric characteristics for its conformation. Objective: This study aimed a...

Stability of the anterior arm of three different Hyrax hybrid expanders: an in vitro study

ABSTRACT Introduction: The force applied to the teeth by fixed orthopaedic expanders has previously been studied, but not the force applied to the orthodontic mini-implant (OMI) used to expand the maxilla with Hyrax hybrid expanders (HHE). Objective: The aim of this article was to evaluate the clinica...

Extruded upper first molar intrusion: Comparison between unilateral and bilateral miniscrew anchorage

ABSTRACT Objective: The aim of his study was to evaluate the stress on tooth and alveolar bone caused by orthodontic intrusion forces in a supraerupted upper molar, by using a three-dimensional Finite Element Method (FEM). Methods: A superior maxillary segment was modeled in the software SolidWorks 2...
