Entirely Exophytic HPV-associated Endocervical Adenocarcinoma: A Rare But Potentially Aggressive Neoplastic Phenomenon.

A subset of human papillomavirus (HPV)-associated endocervical adenocarcinoma (EA) displays exclusively exophytic growth, with or without a classic villoglandular appearance. Given that increased depth and extent of destructive stromal invasion are associated with poorer prognosis for HPV-associated EA, it is believed that exclusively exophytic tumors are associated with a relatively indolent clinical course. There is, however, a paucity of data regarding the behavior of these neoplasms.

Novel frequency selective Bfocusing passive lenz resonators for substantial MRI signal-to-noise ratio amplification.

The need for increased sensitivity in magnetic resonance imaging (MRI) is crucial for its advancement as an imaging modality. The development of passive Lenz Resonators (LRs) for effective RF magnetic field (B) focusing will improve MRI sensitivity via local amplification of MRI signal, thereby leading to more efficient diagnosis and patient treatment.While there are methods for amplifying the signal from specific nuclei in MRI, such as hyperpolarization, a general solution will be more advantageous and would work in combination with these preexisting methods.

Presence and extent of lymphovascular invasion in surgical stage I squamous cell carcinoma of the cervix: a comprehensive, international, multicentre, retrospective clinicopathological study.

The aim of this study was to determine whether the presence and extent of lymphovascular invasion (LVI) is prognostic in surgical stage I cervical squamous cell carcinoma (SCC). All available tumour slides and/or paraffin blocks from 426 patients with stage I cervical SCC treated surgically with curative intent were collected from 18 institutions and retrospectively analysed. Presence and extent of LVI (focal <5 spaces, extensive ≥5 spaces) were assessed on scanning magnification in large haematoxylin and eosin slide sets in 366 cases.

Intraoperative Real-Time Image-Guided Fibular Harvest and Mandibular Reconstruction: A Feasibility Study on Cadaveric Specimens.

Background: This study assesses the feasibility of real-time surgical navigation to plan and guide sequential steps during mandible reconstruction on a series of cadaveric specimens.

Methods: An image-guided surgical (IGS) system was designed including customized mandible and fibula fixation devices with navigation reference frames and an accompanied image-guided software. The mandibular and fibular segmental osteotomies were performed using the IGS in all five cadaveric patients.
