Urology practice during the COVID-19 vaccination campaign
2021
Introduction: The current scenario of the COVID-19 pandemic is significantly different from that of the first, emergency phase. Several countries in the world are experiencing a second, or even a third, wave of contagion, while awaiting the effects of mass vaccination campaigns. The aim of this report was to provide an update of previously released recommendations on prioritization and restructuring of urological activities. Methods: A large group of Italian urologists directly involved in the reorganization of their urological wards during the first and second phase of the pandemic agreed on a set of updated recommendations for current urology practice. Results: The updated recommendations…
[The impact of COVID-19 on hand surgery: a French retrospective comparative study in COVID-19 and non-COVID-19 hand trauma centers].
2021
Introduction: En 2020, la pandémie a divisé la France en zone COVID-19 et non COVID-19. L’objectif principal de notre étude était de comparer la variabilité de l’activité chirurgicale et de consultation de 2 centres SOS main entre la période de pandémie et hors pandémie. Les objectifs secondaires étaient d’identifier les patients à risque afin de développer des moyens de prévention en traumatologie de la main. Méthodes: Il s’agit d’une étude rétrospective bi-centrique à visée épidémiologique sur les admissions aux urgences traumatologiques pendant le premier confinement français. Les données ont été comparées à la même période en 2019 (groupe contrôle). 2055 patients ont consulté pour un tr…
Impact of asymptomatic COVID-19 patients in global surgical practice during the COVID-19 pandemic
2020
The rapid spread of COVID-19 has changed the global surgical care. Patients infected with COVID-19 may present without typical symptoms, and such asymptomatic patients may potentially trigger in-hospital outbreaks by transmitting the disease to health care providers and other hospitalized patients. Further, asymptomatic COVID-19 patients have worse postop- erative outcomes with an unexpectedly high morbidity and mortality, reaching 20⋅5 per cent deaths. However, we do not have objective global data on this issue. In an attempt to clarify the current global surgical practice under the COVID-19 pandemic particularly focusing on the preoperative screening of asymptomatic COVID-19 patients, we …
The application of 3d printing in plastic and reconstructive surgery: Case-control study in facial reconstruction
2017
The aim of this study was to explore the efficiency and usefulness of tridimensional printing in plastic and reconstructive surgery for lesions of the maxillofacial region. This was comparison study between two groups of patients. Six patients underwent surgical reconstruction, using a threedimensional model built on the basis of CT scans (group 1); and six patients underwent surgical reconstruction, without the use of a three-dimensional model (group 2). The following variables were evaluated: age, gender, histological diagnosis, cancer location, size of bone lesion, type of reconstruction, complications and surgical timing. A statistically significant difference was found in microsurgical…
Real-time simulation of tissue deformation for the nasal endoscopy simulator (NES).
1999
Endonasal sinus surgery requires a great amount of training before it can be adequately performed. The complicated anatomy involved, the proximity of relevant structures, and the variability of the anatomy due to inborn or iatrogenic variations make several complications possible. Today, cadaver dissections are the "gold standard" for surgical training. To overcome the drawbacks of traditional training methods, the Fraunhofer Institute for Computer Graphics is currently developing a highly interactive medical simulation system for nasal endoscopy and endonasal sinus surgery, in cooperation with the Mainz University Hospital. For the simulation of a rhinoscopic procedure, not only are the re…
Aktuelle Entwicklungen und Perspektiven in der Diagnostik und Therapie von Harninkontinenz und Genitalsenkung der Frau
2013
As a key area of gynaecology, urogynaecology has undergone impressive changes in the past few years. Together with the high prevalence of functional pelvic floor disorders, modern anaesthesia procedures and the introduction of new, innovative minimally invasive operation techniques have led to a dramatic increase in the number of operations for incontinence and prolapses. The increasingly subtle diagnostic options, such as, e. g., 2D and 3D sonography of the pelvic floor provide unambiguous findings and facilitate decision making. Tension-free vaginal slings in retro-pubic, trans-obturator or single-incision techniques show a high success rate with few complications and have almost complete…
Changes in tear film metrics and ocular signs induced by different types of refractive correction in an aging population
2018
La integridad de la superficie ocular, en otras palabras, su capacidad para responder adecuadamente a los desafíos ambientales, depende de la integración adecuada de la información desde la superficie ocular, la transmisión de la señal creada hacia el cerebro y la generación de una respuesta, que modulará la función secretora así como la inmunidad local de la superficie ocular. Es fácilmente comprensible que cualquier alteración de uno de los tres pasos de este ciclo cerrado pueda desencadenar una respuesta inapropiada y desequilibrar aún más los mecanismos compensatorios que tienen lugar en la superficie ocular. La unidad funcional de la lágrima se puede definir como un conjunto de estruct…
Recomendaciones en el manejo de la pandemia por coronavirus SARS-CoV-2 (Covid-19) en pacientes con trasplante renal
2020
The SARS-CoV-2 (Covid-19) coronavirus pandemic is evolving very quickly and means a special risk for both immunosuppressed and comorbid patients. Knowledge about this growing infection is also increasing although many uncertainties remain, especially in the kidney transplant population. This manuscript presents a proposal for action with general and specific recommendations to protect and prevent infection in this vulnerable population such as kidney transplant recipients. Resumen: La pandemia por coronavirus SARS-CoV-2 (Covid-19) está evolucionando de manera muy rápida y representa un riesgo especial en pacientes inmunodeprimidos y con comorbilidades añadidas. El conocimiento sobre esta in…

SHORTNESS OF FILUM TERMINALE REPRESENT AN ANATOMICAL SPECIFC FEATURES IN FIBROMYALGIIA : A NUCLEAR MAGNETIC RESONANCE AND CLINICAL STUDY
2015
BACKGROUND: we aimed to assess whether shortness of filum terminale (FT) can represent a specific feature of fibromyalgia. Therefore we investigated benefits coming from FT section with a mini-invasive technique in patients with fibromyalgia. Filum terminale disease (FD), described firstly in 1996, is consequence of an abnormal traction exerted on spinal cord since FT is shorter than usual. Fibromyalgia syndrome (FS) is featured by chronic widespread musculoskeletal pain associated with stiffness and extra-skeletal symptoms affecting many organs and systems. Filum terminale disease and fibromyalgia syndrome share common clinical features in at least one subset of patients. METHODS: we evalu…
