DIFFERENT LOCATIONS OF ENDOMETRIOSIS IN 86 PATIENTS: A SINGLE- CENTRE STUDY.

2015

Endometriosis is an important gynecologic disorder defined as the presence of functional endometrial glands and stroma outside the uterine cavity. Prevalence of endometriosis is 6-10% in the general population, but rises to 35-50% in women with pelvic pain or infertility or both. The aim of this study was to retrospectively review the different locations of pelvic and extrapelvic endometriosis occurred in our Department during last 3 years.

Volumetric Enhancing Tumor Burden at CT to Predict Survival Outcomes in Patients with Neuroendocrine Liver Metastases after Intra-arterial Treatment

2023

Purpose To investigate whether liver enhancing tumor burden (LETB) assessed at contrast-enhanced CT indicates early response and helps predict survival outcomes in patients with multifocal neuroendocrine liver metastases (NELM) after intra-arterial treatment. Materials and Methods This retrospective study included patients with NELM who underwent intra-arterial treatment with transarterial embolization (TAE) or chemoembolization (TACE) between April 2006 and December 2018. Tumor response in treated NELM was evaluated by using the Response Evaluation Criteria in Solid Tumors (RECIST) and modified RECIST (mRECIST). LETB was measured as attenuation 2 SDs greater than that of a region of intere…

Impact of molecular and histological subtype of breast cancer on 18FDG-PET/CT imaging: Knowledge gained from recent studies

2016

International audience; Over the past few years, several studies have focused attention on the impact of breast cancer (BC) histological subtype or BC phenotype, as defined by hormone receptors (HR) and HER2 status, on the results of FDG-PET/CT at staging, or during neoadjuvant chemotherapy (NAC). At staging, sclerotic bone metastases from invasive lobular carcinoma (ILC) demonstrated low or no FDG uptake in comparison to metastases from invasive ductal carcinoma (IDC). The CT component of PET/CT imaging should be carefully analyzed in the staging of ILC. In patients with triple negative or HER2-positive tumors, the proportion of extraskeletal metastases is high; this must be taken into acc…

CTLA4-Linked Autoimmunity in the Pathogenesis of Endometriosis and Related Infertility: A Systematic Review

2022

Several studies, although with conflicting results, have sought to determine the concentration of soluble CTLA4 antigens in peripheral blood plasma and peritoneal fluid in patients with endometriosis-related infertility. A systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) through a search of the following databases: MEDLINE, EMBASE, Global Health, The Cochrane Library, Health Technology Assessment Database and Web of Science, and Clinical Trials research register. We included observational or prospective human and animal studies with any features related to endometriosis and/or infertility studies involving CTLA4-rel…

Unusual imaging manifestation of severe bilateral cochlear otosclerosis: a case report

2018

A xanthogranulomatous process resembling residual disease on endof- treatment 18f-FDG-PET/CT and Whole Body Magnetic Resonance performed on a primary…

2016

We report the case of a woman, affected by breast diffuse large B-Cell lymphoma, who developed a xanthogranulomatous process wrongly interpreted as residual disease on 18F-FDG-PET/CTand Whole Body Magnetic Resonance after treatment with ibrutinib plus standard immunochemotherapy. Newer drugs, such as immunomodulatory agents and checkpoint inhibitors, have demonstrated high effectiveness on lymphoma, but are associated with unclear imaging features such as tumor flare or pseudo-progression, related to inflammatory reactions. Wide imaging techniques availability improves diagnostic possibilities. However, the awareness of the adopted treatment strategy and its possible implications on imaging…

Assessment of the CTOCD-DZ methodin a hierarchy of coupled cluster methods

2010

Gauge origin independent calculations of nuclear magnetic shielding tensors are carried out inside the formalism of the continuous transformation of the origin of the current density leading to formal annihilation of its diamagnetic contribution (CTOCD-DZ). We employ the unrelaxed linear response approach with a hierarchy of different coupled cluster methods in order to assess the importance of the level of approximation in the coupled cluster expansion. The basis set dependence of the computed nuclear magnetic shielding constants is also analyzed in the series of correlation consistent basis sets, with the aim of designing optimized basis sets of relatively small size.

An edge-driven 3D region-growing approach for upper airway morphology and volume evaluation in patients with Pierre Robin sequence

2015

Abstract: Pierre Robin sequence (PRS) is a pathological condition responsible for a sequence of clinical events, such as breathing and feeding difficulties, that must be addressed to give the patient at least a chance to survive. By using medical imaging techniques, in a non-intrusive way, the surgeon has the opportunity to obtain 3D views, reconstruction of the regions of interest (ROIs), useful to increase understanding of the PRS patient’s condition. In this paper, a semi-automatic approach for segmentation of the upper airways is proposed. The implemented approach uses an edge-driven 3D region-growing algorithm to segment ROIs and 3D volume-rendering technique to reconstruct the 3D mode…
