OBJECTIVE This study evaluated the influence of metallic dental artifacts on the accuracy of simulated mandibular lesion detection by using multislice technology. MATERIAL AND METHODS Fifteen macerated mandibles were used. Perforations were done simulating bone lesions and the mandibles were subjected to axial 16 rows multislice CT images using 0.5 mm of(More)
Intracystic papillary carcinoma (IPC) of the breast is a rare tumor with predilection for elderly women and distinctive pathological features that must be distinguished from ductal carcinoma in situ (DCIS) of papillary type and from invasive papillary carcinoma. The clinical, radiological, and pathological features of 29 cases of IPC are reported. The cases(More)
INTRODUCTION This article is part of the Focus Theme of Methods of Information in Medicine on "Methodologies, Models and Algorithms for Patients Rehabilitation". BACKGROUND ICT is an emerging alternative to paper-and-pencil tests for the assessment of cognitive functions, allowing for the monitoring of participants' behavior while they perform simulations(More)
INTRODUCTION This article is part of the Focus Theme of Methods of Information in Medicine on "New Methodologies for Patients Rehabilitation". BACKGROUND The ecological validity of paper-and-pencil neuropsychological tests is currently a matter of debate. Arguments in favor of alternatives indicate that paper-and-pencil forms are unable to account for(More)
OBJECTIVE The purpose of this research was to provide further evidence to demonstrate the precision and accuracy of maxillofacial linear and angular measurements obtained by cone-beam computed tomography (CBCT) images. STUDY DESIGN The study population consisted of 15 dry human skulls that were submitted to CBCT, and 3-dimensional (3D) images were(More)
Apocrine ductal carcinoma in situ (ADCIS) has been called a special type of ductal carcinoma in situ (DCIS) because the histologic grading is considered difficult using the classification schemes that have been proposed for common DCIS. However, ADCIS encompasses a spectrum of lesions with different morphologic aspects ranging from minimally atypical to(More)
Calcifying epithelial odontogenic tumor (CEOT) is a rare, locally invasive neoplasm characterized by the presence of amyloid material that can become calcified. It often is found in the posterior region of the mandible. Such tumors in the maxilla and those that invade the maxillary sinus are extremely rare. This article presents the sixth reported clinical(More)
The MSH2 c.388_389del mutation has occasionally been described in Lynch families worldwide. At the Portuguese Oncology Institute in Porto, Portugal, we have identified 16 seemingly unrelated families with this germline mutation. To evaluate if this alteration is a founder or a recurrent mutation we performed haplotype analysis in the 16 Portuguese index(More)
OBJECTIVES The purpose of this study was to evaluate and to compare the validity of the different CT image protocols (single- and multislice CT) in the analysis of simulated mandibular condyle lesions. METHODS Simulated lesions were created in 15 dry mandibles using a dental round burr. The mandibles were then submitted to a single slice CT, and the same(More)
OBJECTIVE This study was designed to determine the precision and accuracy of angular measurements using three-dimensional computed tomography (3D-CT) volume rendering by computer systems. STUDY DESIGN The study population consisted of 28 dried skulls that were scanned with a 64-row multislice CT, and 3D-CT images were generated. Angular measurements, (n =(More)
