Cirugía de las arritmias en las cardiopatías congénitas
2008
La propia fisiopatología de las cardiopatías congénitas y el impacto de algunas correcciones quirúrgicas pueden predisponer al desarrollo de arritmias cardíacas, que incluyen taquicardia supraventricular macrorreentrante, flutter, fibrilación auricular, taquicardia auricular ectópica, taquicardia ventricular, síndrome del seno enfermo, bloqueo auriculoventricular y muerte súbita, entre otras. En la actualidad el tratamiento definitivo de estas arritmias y su profilaxis durante la corrección quirúrgica son procesos eficaces, con baja morbilidad y gran beneficio clínico para el paciente. En este trabajo se revisa el estado actual del tratamiento quirúrgico de las arritmias en las cardiopatías…
How Can the COVID-19 Pandemic Lead to Positive Changes in Urology Residency?
2020
The COVID-19 outbreak, in a few weeks, overloaded Italian hospitals, and the majority of medical procedures were postponed. During the pandemic, with hospital reorganization, clinical and learning activities performed by residents suffered a forced remodulation. The objective of this study is to investigate how urology training in Italy has been affected during the COVID-19 era. In this multi-academic study, we compared residents' training during the highest outbreak level with their previous activity. Overall 387 (67.1%) of the 577 Italian Urology residents participated in a 72-h anonymous online survey with 36 items sent via email. The main outcomes were clinical/surgical activities, soci…
Investigation of Tinnitus Patients in Italy: Clinical and Audiological Characteristics
2010
Objective. 312 tinnitus sufferers were studied in order to analyze: the clinical characteristics of tinnitus; the presence of tinnitus-age correlation and tinnitus-hearing loss correlation; the impact of tinnitus on subjects' life and where possible the etiological/predisposing factors of tinnitus.Results. There is a slight predominance of males. The highest percentage of tinnitus results in the decades 61–70. Of the tinnitus sufferers, 197 (63.14%) have a hearing deficit (light hearing loss in 37.18% of cases). The hearing impairment results of sensorineural type in 74.62% and limited to the high frequencies in 58.50%. The tinnitus is referred as unilateral in 59.93%, a pure tone in 66.99%…
Liver Preservation by Aortic Perfusion Alone Compared With Preservation by Aortic Perfusion and Additional Arterial Ex Situ Back-Table Perfusion With…
2017
Background. Arterial ex situ back-table perfusion (BP) reportedly reduces ischemic-type biliary lesion after liver transplantation. We aimed to verify these findings in a prospective investigation. Methods. Our prospective, randomized, controlled, multicenter study involved livers retrieved from patients in 2 German regions, and compared the outcomes of standard aortic perfusion to those of aortic perfusion combined with arterial ex situ BP. The primary endpoint was the incidence of ischemic-type biliary lesions over a follow-up of 2 years after liver transplantation, whereas secondary endpoints included 2-year graft survival, initial graft damage as reflected by transaminase levels, and fu…
Milan-out Criteria and Worse Intention-to-Treat Outcome Postliver Transplantation
2019
Background. Milan criteria are widely used for liver transplantation selection in hepatocellular carcinoma but have been recognized to be too restrictive. Milan-out criteria are increasingly being adopted. Our aim was to analyze if liver transplantation waitlisted Milan-out hepatocellular carcinoma patients have different outcome than Milan patients. Methods. Retrospective study including all consecutive patients with hepatocellular carcinoma admitted in the waiting list for liver transplantation between January 2012 and January 2015. We included 177 patients, 146 of which eventually transplanted. Downstaging was achieved in the Milan-out cases (n = 29) before waitlisting. Results. From dia…
Laparoscopic management of an isolated left fallopian tube torsion due to twisted Morgagni hydatid in a pre-menarcheal girl.
2014
Isolated torsion of fallopian tube, meanwhile uncommon, should be considered in diagnosis of pelvic and lower abdominal pain. US investigation is an useful diagnostic tool. A prompt diagnosis could avoid salpingectomy and preserve fertility. Laparoscopy, as the first approach, should be preferred. We report a case of isolated tubal torsion occurring in a premenarcheal girl successfully managed by laparoscopy.
Tumor mixoide de cayado aórtico: a propósito de un caso
2010
Las neoplasias aórticas son una rara causa de embolia sistémica y normalmente se descubren a partir de un defecto de repleción en las pruebas de imagen. Presentamos el caso clínico de un varón de 52 años de edad que sufre un episodio de isquemia aguda del miembro superior derecho a raíz de la cual es descubierta y tratada una neoplasia íntimal de cayado aórtico. Se aporta revisión de la literatura sobre la evidencia en el manejo de este tipo de entidades.Aortic tumors are a rare cause of systemic embolisation and usually discovered through an image of repletion defect. We present the case of a 52-year-old male with an acute ischemic right upper limb which led to the diagnosis and treatment …
Comparative study assessing effects of sonic hedgehog and VEGF in a human co-culture model for bone vascularisation strategies.
2011
The morphogen sonic hedgehog (Shh) seems to mediate adult repair processes in bone regeneration and vascularisation. In this study we investigated the effects of Shh on co-cultures consisting of human primary osteoblasts and outgrowth endothelial cells in terms of angiogenic activation and vessel maturation in comparison to the treatment with the commonly used proangiogenic factor, VEGF. Both, stimulation with VEGF or Shh, leads to an increase in the formation of microvessel-like structures compared to untreated controls. In contrast to VEGF, proangiogenic effects by Shh could already be observed after 24 h of treatment. Nevertheless, after 14 days the angiogenic activity of OEC was compara…

El tendón de Aquiles de la cirugía coronaria: el ictus postoperatorio
2017
Resumen Los pacientes con factores de riesgo preexistentes de enfermedad cerebrovascular tienen durante la cirugia coronaria un mayor riesgo de presentar un ictus postoperatorio. Entre los principales factores de riesgo a considerar esta la edad, las comorbilidades y la tecnica quirurgica, en especial la manipulacion de la aorta. Este articulo revisa la informacion medico-quirurgica actual de la lesion neurologica tipo ictus durante la CABG aislada.
