Malignes fibröses Histiozytom

1988

Malignant fibrous histiozytoma (MHF) is a pleomorphic sarcoma of ubiquituous origin. The clinical and radiological features of the tumor are illustrated by 23 patients with MFH of soft tissue and 4 MFH of bone. On conventional radiography MFH appears as a soft tissue tumor, sometimes with bone involvement; on sonography it is usually non-homogeneous and hypoechogenic with areas of necrosis. On CT the masses are homogeneous or inhomogeneous (10-60 HU.) containing areas of decreased density. Contrast enhancement was about 10-20 HU. Angiographically the tumor appears as hypo- or hypervascular with pathologic vessels. The morphology of MFH in diagnostic imaging including magnetic resonance tomo…

Accuracy and Safety of Ultrasound-Guided Core Needle Biopsy of Soft Tissue Tumors in an Outpatient Setting: A Sarcoma Center Analysis of 392 Consecut…

2021

Simple Summary In patients with unclear soft tissue lesions, treatment planning largely depends on histology. Core needle biopsy is the diagnostic standard in these cases. The aim of this retrospective study was to investigate accuracy and safety of ultrasound guided core needle biopsy at a tertiary referral center. We show that ultrasound guided biopsy was feasible as a one stop shop procedure in an outpatient setting in 87.6% of the cases. The rate of conclusive biopsies was 88.5%. After surgical resection, the dignity, tumor type and histopathological grading of the biopsy matched one of the resection specimens in 97.2%, 92.7% and 92.5% of the cases, respectively. Major complications occ…

Waiting for a new leader: Eras and transitions in Cosa Nostra

2019

Partendo dal controverso dibattito che negli ultimi anni ha visto in Italia – soprattutto i mezzi di comunicazione di massa e le agenzie investigative – disputare sullo “stato di salute” delle organizzazioni criminali mafiose, quasi a volerne stilare una discutibile classifica di offensività e di pericolosità, il capitolo si interroga sull’attuale e delicata fase attraversata da Cosa Nostra, facendo ricorso a una prospettiva analitica multiproblematica e multidisciplinare (rielaborando il cosiddetto paradigma della complessità proposto da Umberto Santino alla luce dei più recenti studi e delle nuove prospettive analitiche emerse) e dando conto delle numerose ricerche (oggi spesso orientate …

Plastic and cosmetic surgery of the male breast

2020

The thorax has a fundamental role in the aesthetic of the male body: Congenital or acquired alterations are experienced as extremely frustrating clinical situations. Most breast surgery texts briefly mention gynecomastia, but no text comprehensively addresses the male breast and thorax, including reconstructive and cosmetic surgery and surgery in transgender patients. This gap is now thoroughly filled by Plastic and Cosmetic Surgery of the Male Breast: After introducing principles of anatomy and aesthetics for the male thorax, the first part focusses on the main congenital malformations and their treatment; the main benign acquired pathologies and their treatment (including an ample section…

La identidad Neozapatista como proceso comunicativo

2018

International audience; This article studies the speech and the political action of the Zapatista movement,considering both as a communicative practice that is articulated among a plurality of uses and“cultural matrices” (Martín Barbero, 1987) in what has constituted the Neozapatista social subject.Firstly, the discursive aspects of the Zapatista statements are reviewed, with their narrativestrategies, key representations and conditions of reproduction. Secondly, an emphasis is made onthe systematic study of its political-media trajectory throughout its already long history, analyzingthe conventions, the encounters and other Zapatista actions and political initiatives. The resultsoffer an o…

Antitumor Effects of a Combined 5-Aza-2′Deoxycytidine and Valproic Acid Treatment on Rhabdomyosarcoma and Medulloblastoma in Ptch Mutant Mice

2009

Abstract Patched (Ptch) heterozygous mice develop medulloblastoma (MB) and rhabdomyosarcoma (RMS) resembling the corresponding human tumors. We have previously shown that epigenetic silencing of the intact Ptch allele contributes to tumor formation in this model. Here, we investigated whether targeting of epigenetic silencing mechanisms could be useful in the treatment of Ptch-associated cancers. A reduction of endogenous DNA methyltransferase1 (Dnmt1) activity significantly reduced tumor incidence in heterozygous Ptch knockout mice. A combined treatment with the Dnmt inhibitor 5-aza-2′deoxycytidine (5-aza-dC) and the histone deacetlyase (HDAC) inhibitor valproic acid (VPA) efficiently prev…

Agreement among 3 optical imaging methods for the assessment of optic disc topography.

2005

Purpose To assess the agreement of disc topography measurements between the Heidelberg Retina Tomograph (HRT II), Retinal Thickness Analyzer (RTA), and Optical Coherence Tomograph (StratusOCT). Design Observational cross-sectional study. Participants Forty-two randomly chosen eyes of 42 subjects. Methods Each subject underwent HRT II, RTA, and StratusOCT examination. Two experienced examiners drew the contour lines for the HRT II and RTA. Bland and Altman plots were used to evaluate agreement for each topographic parameter among the instruments. The Spearman coefficient of rank correlation was evaluated for each topographic parameter. Main Outcome Measures Agreement in the measurement of op…

Resumen tomado de la publicación La mejor estrategia para prevenir la expansión del VIH-SIDA es la prevención. Son bien conocidas las medidas de prevención, de las que se han realizado una enorme difusión. La transmisión del VIH-SIDA por inaplicación de las medidas de prevención por personas afectadas de modo deliberado y sin comunicación del estado serológico comporta, según diversas sentencias de nuestros Tribunales, sanciones penales o civiles. No obstante, hay que tener en cuenta las circunstancias de las personas en estado de intoxicación por consumo de drogas y alcohol y el consentimiento de la persona que se expone a la transmisión del virus, puesto que podría dar lugar a exoneración…
