Advanced Female Primary Urethral Carcinoma with Nodal Extension Managed with Exclusive Use of Chemoradiotherapy: Report of a Case and Review of the Relevant Current Literature.

Primary urethral carcinoma (PUC) is a rare disease with frequent nodal metastasis at the time of diagnosis. Few risk factors have been established and overall prognosis remains poor. As of now, no clear therapeutic guidelines are established and management of advanced PUC often involves surgery which can have negative functional and psychological outcomes for the patient.

Evaluation of the multimorbidity network and its relationship with clinical phenotypes in chronic obstructive pulmonary disease: The GALAXIA study.

Background: Chronic obstructive pulmonary disease (COPD) is a complex and heterogeneous condition, in which taking into consideration clinical phenotypes and multimorbidity is relevant to disease management. Network analysis, a procedure designed to study complex systems, allows to represent connections between the distinct features found in COPD.

Methods: Network analysis was applied to a cohort of patients with COPD in order to explore the degree of connectivity between different diseases, taking into account the presence of two phenotypic traits commonly used to categorize patients in clinical practice: chronic bronchitis (CB /CB ) and the history of previous severe exacerbations (Ex /Ex ).

Inter-observer agreement for the histological diagnosis of invasive lobular breast carcinoma.

Invasive lobular breast carcinoma (ILC) is the second most common breast carcinoma (BC) subtype and is mainly driven by loss of E-cadherin expression. Correct classification of BC as ILC is important for patient treatment. This study assessed the degree of agreement among pathologists for the diagnosis of ILC.

Interobserver variability in the assessment of stromal tumor-infiltrating lymphocytes (sTILs) in triple-negative invasive breast carcinoma influences the association with pathological complete response: the IVITA study.

High stromal tumor-infiltrating lymphocytes (sTILs) in triple-negative breast cancer (TNBC) are associated with pathological complete response (pCR) after neoadjuvant chemotherapy (NAC). Histopathological assessment of sTILs in TNBC biopsies is characterized by substantial interobserver variability, but it is unknown whether this affects its association with pCR. Here, we aimed to investigate the degree of interobserver variability in an international study, and its impact on the relationship between sTILs and pCR.

The COPD Comorbidome in the Light of the Degree of Dyspnea and Risk of Exacerbation.

The BODE group designed a bubble chart, analogous to the solar system, which depicts the prevalence of each disease and its association with mortality and called it a "comorbidome". Although this graph was used to represent mortality and, later, the risk of needing hospital admission, it was not applied to visualize the association between a set of comorbidities and the categories of the GOLD 2017 guidelines, neither according to the degree of dyspnea nor to the risk of exacerbation. For the purpose of knowing to which extent each comorbidity associates with each of the two conditions-most symptomatic group (groups B and D) and highest risk of exacerbation (groups C and D)-we performed a analysis based on the comorbidome.

Health Status in Patients with COPD According to GOLD 2017 Classification: Use of the COMCOLD Score in Routine Clinical Practice.

The COMCOLD score was developed to quantify the impact of comorbidities on health status in patients with chronic obstructive pulmonary disease (COPD). The objective of this study is to evaluate the association between health status in outpatients with COPD according to COMCOLD score and the GOLD 2017 groups according to symptoms (B and D vs. A and C) and exacerbations (C and D vs.

Aquaporin expression in blood-retinal barrier cells during experimental autoimmune uveitis.

Purpose: Blood-retinal barrier (BRB) breakdown and retinal edema are major complications of autoimmune uveitis and could be related to deregulation of aquaporin (AQP) expression. We have therefore evaluated the expression of AQP1 and AQP4 on BRB cells during experimental autoimmune uveitis (EAU) in mice.

Methods: C57Bl6 mice were immunized with interphotoreceptor retinoid-binding protein (IRBP) peptide 1-16.

Nodal-stage classification in invasive lobular breast carcinoma: influence of different interpretations of the pTNM classification.

PURPOSE Application of current nodal status classification is complicated in lobular breast carcinoma metastases. The aim of this study was to define the optimal interpretation of the pTNM classification in sentinel node (SN) -positive patients to select patients with limited or with a high risk of non-SN involvement. PATIENTS AND METHODS SN metastases of 392 patients with lobular breast carcinoma were reclassified according to interpretations of the European Working Group for Breast Screening Pathology (EWGBSP) and guidelines by Turner et al, and the predictive power for non-SN involvement was assessed.

Eighteen months clinical experience with the GeneSearch breast lymph node assay.

Background: The accuracy of a molecular reverse transcriptase-polymerase chain reaction (RT-PCR)-based assay for metastases detection in axillary sentinel lymph nodes (SLNs) has recently been validated in our institution and adopted as an intraoperative test for breast cancer patient management.

Methods: Molecular assay performance was compared to standard postoperative histology in 253 consecutive patients with clinically node-negative T1 early breast cancer (<2 cm).

Results: The molecular assay correctly identified 26/27 macrometastases and 11/15 micrometastases.

Recombinant adenovirus administration in rat peritoneum: endothelial expression and safety concerns.

Background: Initial studies of adenovirus-mediated gene transfer to the peritoneum have shown transgene expression in the mesothelium from the parietal peritoneum. Using a replication-deficient adenovirus encoding beta-galactosidase (Ad beta Gal), we investigated the expression efficiency and the distribution of the transgene to different areas of both visceral and parietal peritoneum and to extra-peritoneal tissues.

Methods: Male Wistar rats received an intraperitoneal injection of 15 ml of 0.
