Neurofibroma plexiforme en mucosa yugal: presentación de un caso clínico

2004

Presentamos un caso clínico de neurofibroma plexiforme localizado en región geniana, a nivel submucoso. Su interés radica en que, a pesar de ser el tumor de origen neurógeno más frecuente, es una entidad poco habitual y que rara vez se localiza a nivel intraoral. Por otra parte, la variedad plexiforme es todavía menos frecuente. Desde el punto de vista clínico, se manifiestan como lesiones anodinas, con escasa sintomatología, que cuando aparece es derivada de la compresión nerviosa. En nuestro caso el tumor era asintomático salvo por el tamaño. Radiológicamente no existe una imagen definitiva. Tiene relación con determinados síndromes poliglandulares y facomatosis. El tratamiento es básicam…

A rare case of ulcerative proctitis associated with type B lymphomatoid papulosis and superimposed human cytomegalovirus infection.

Ultraviolet A1 radiation induces nitric oxide synthase-2 expression in human skin endothelial cells in the absence of proinflammatory cytokines.

2001

Skin exposure to ultraviolet radiation from sunlight causes erythema and edema formation as well as inflammatory responses. As some of these ultraviolet-induced effects are potentially mediated by nitric oxide synthases, we examined the role of cytokines and ultraviolet A 1 radiation (340–400 nm) on the expression of the nitric oxide synthase-2 in endothelia of normal human skin biopsies during short-term organ culture as well as expression and activity of the nitric oxide synthase-2 in in vitro cell cultures of human dermal endothelial cells. Both, cytokine challenge (interleukin-1β + tumor necrosis factor-α + interferon-γ) but also ultraviolet A 1 exposure (50 J per cm 2 ) in the absence …

Maxillary necrosis by mucormycosis : a case report and literature review

2007

The maxilla rarely undergoes necrosis due to its rich vascularity. Maxillary necrosis can occur due to bacterial infections such as osteomyelitis, viral infections such as herpes zoster or fungal infections such as mucormycosis, aspergillosis etc. Mucormycosis is an opportunistic fulminant fungal infection, which mainly infects immunocompromised patients. The infection begins in the nose and paranasal sinuses due to inhalation of fungal spores. The infection can spread to orbital and intracranial structures either by direct invasion or through the blood vessels. The fungus invades the arteries leading to thrombosis that subsequently causes necrosis of hard and soft tissues. We report a case…

Real-world experience with obeticholic acid in patients with primary biliary cholangitis

2021

Background & aims Obeticholic acid (OCA) is the second-line treatment approved for patients with primary biliary cholangitis (PBC) and an inadequate response or intolerance to ursodeoxycholic acid. We aimed to evaluate the effectiveness and safety of OCA under real-world conditions. Methods Patients were recruited into the Italian PBC Registry, a multicentre, observational cohort study that monitors patients with PBC at national level. The primary endpoint was the biochemical response according to Poise criteria; the secondary endpoint was the biochemical response according to normal range criteria, defined as normal levels of bilirubin, alkaline phosphatase (ALP), and alanine aminotransfer…

Experiences of anamorphosis between poetry, architecture, and social context: interview with Boa Mistura

2020

The paper presents an interview with Boa Mistura, a multidisciplinary Madrid art collective that works all over the world and creates urban works based on the use of anamorphosis and the visual perception of urban spaces.The Boa Mistura projects are “site specific”, they are designed for a specific space and place. In the interview we explore the relationship between urban art and physical context, the way in which the works adapt to the surfaces and volumes on which they are made.The physical support of the works of Boa Mistura is often made up of separate and not coplanar surfaces and of volumes, sometimes disjointed, on which the murals recline. The same historiated surfaces determine the …

Urban Landscapes and Resilience. Exploring an adaptive design perspective

2017

Il concetto di resilienza in pianificazione è emerso in tempi recenti come un mezzo potente per sostenere la ricerca e l'innovazione sua nella teoria che nella pratica. Partendo da una definizione delle città come sistemi adattivi complessi, organismi viventi in un contesto di non-equilibrio e spazi di intensa interazione e interdipendenza uomo-natura, il contributo intende esplorare il ruolo dei servizi ecosistemici nella costruzione della resilienza urbana. Il cambiamento globale e l'incertezza richiedono un approccio strategico verso la resilienza urbana, attraverso l'adaptive design. Mentre una visione basata sullo stato di equilibrio tende a guardare alla forma urbana ideale, riconosce…

Tendon length estimates are influenced by tracking location

2022

Abstract Purpose Measurement of medial gastrocnemius (MG) tendon length using ultrasonography (US) requires the muscle–tendon junction (MTJ) to be located. Previously, the MG MTJ has been tracked from different proximo-distal locations near the MTJ, which could influence estimates of tendon length change due to the different characteristics of the aponeurosis and tendon. We used US to evaluate the effect of tracking point location on MG MTJ displacement during maximal and submaximal (10, 20 and 30% of the non-injured maximal) isometric plantar flexion contractions. Methods Displacement behaviour of MTJ was tracked from (1) the exact MTJ; and (2) from an insertion point of a muscle fascicle …

Los saberes en torno a la tuberculosis en Valencia a través de la prensa médica (1882-1914)

2011

Para la realización de este trabajo se ha partido del interés que tiene estudiar la literatura científica que a finales del siglo XIX y principios del XX dedicó una sociedad como la valenciana al tema de la tuberculosis, de primera importancia no solo en la realidad epidemiológica de la época, sino también para la constitución de la ciencia y las prácticas médicas contemporáneas. Se ha abordado el estudio de los saberes en torno a la tuberculosis en Valencia a través de las revistas médicas publicadas en ella entre 1882 y 1914, periodo en el que se descubrió el origen microbiano de la enfermedad y se desarrollaron nuevas técnicas diagnósticas, preventivas y curativas de la infección tubercu…
