Small-diameter titanium grade IV and titanium-zirconium implants in edentulous mandibles: five-year results from a double-blind, randomized controlle…
2015
BACKGROUND The aim of this study was to compare the 5-year survival and success rates of 3.3 mm dental implants either made from titanium-zirconium (TiZr) alloy or from Grade IV titanium (Ti Grade IV) in mandibular implant-based removable overdentures. METHODS The core study had a follow-up period of 36 months and was designed as a randomized, controlled, double-blind, split-mouth multicenter clinical trial. Patients with edentulous mandibles received two Straumann Bone Level implants (diameter 3.3 mm, SLActive®), one of TiZr (test) and one of Ti Grade IV (control), in the interforaminal region. This follow-up study recruited patients from the core study and evaluated the plaque and sulcus …
LA TUTELA DEL TERZO NEL PROCEDIMENTO DI ESPROPRIAZIONE DI CREDITI DOPO LA LEGGE 24 DICEMBRE 2012, N. 228 COME MODIFICATA DAL D.L. 12 SETTEMBRE 2014, …

L'indagine affronta il tema dell'espropriazione presso terzi con particolare riguardo alla tutela del terzo, alla luce delle due riforme introdotte con legge 22 dicembre 2012, n. 228 e con d.l. 12 settembre 2014, n. 132, modificato in sede di conversione. Il particolare l'autore, dopo avere esaminato le novità introdotte dalle due riforme, esamina il particolare rimedio dell'opposizione ex art. 548 c.p.c. Conclude che lo strumento in questione costituisce una opposizione tardiva, analoga agli altri istituti analoghi previsti dal codice. Ne consegue che i requisiti previsti dalla norma, secondo cui il terzo potrà impugnare l'ordinanza "se prova di non averne avuto tempestiva conoscenza per i…

Soft tissue integration of different abutment surfaces: An experimental study with histological analysis
2021
OBJECTIVE To evaluate whether abutment surface and surface bio-activation have an effect on soft tissue morphogenesis. MATERIALS AND METHODS 36 patients (36 implants) were included. Abutments were randomly divided into 4 groups (n = 9): Smooth Surface-MAChined (MAC), Ultrathin Threaded Microsurface (UTM), MAC Plasma of Argon activated (Plasma-MAC), and UTM Plasma of Argon activated (Plasma-UTM). After 2 months of healing, soft tissue samples were collected and prepared for histological analysis. The margin of the peri-implant mucosa (PM), the apical extension of the barrier epithelium (aJE), and the apical location of the abutment (AM) were identified. Significances of differences among gro…
Valoración de la regeneración ósea en un modelo animal: Utilización del plasma rico en plaquetas en la curación de los defectos óseos. Estudio prelim…
2007
INTRODUCCIÓN: Los factores de crecimiento y otras moléculas con capacidad osteoinductora pueden considerarse biomateriales que poseen actividad importante en los procesos de reparación y regeneración de los seres vivos. Esta capacidad puede utilizarse para favorecer, asegurar y aumentar lo procesos de reparación del tejido óseo. En esta tesis doctoral se realiza el estudio de la aplicación aislada en un defecto óseo, de un compuesto rico en plaquetas y factores de crecimiento, el plasma rico en plaquetas (PRP).MATERIAL Y MÉTODO: Hemos realizado un estudio experimental prospectivo, comparativo bilateral y controlado, interviniendo quirúrgicamente 30 conejos raza Nueva Zelanda, a los que se p…
Wild-type JAK2 secondary acute erythroleukemia developing after JAK2-V617F-mutated primary myelofibrosis.
2009
A 54-year-old female patient developed acute erythroleukemia after an 8-year course of primary myelofibrosis. The latter harbors the JAK2-V617F mutation and was treated with hydroxyurea and anagrelide. A bone marrow trephine biopsy disclosed 2 morphologically distinct areas of chronic primary myelofibrosis and acute erythroleukemia. Microdissection and a separate molecular pathological analysis was performed. Although the activating JAK2-V617F mutation was not maintained in blasts of acute erythroleukemia, it was detectable in the chronic phase of primary myelofibrosis, indicating that this mutation did not play a role in the leukemic transformation of erythroid cells.
Development of a European consensus from dentists, dental hygienists and physicians on a standard for oral health care in care-dependent older people…
2020
ObjectivesThis study aimed to obtain a consensus on oral health policy, access to dental care, oral hygiene measures and training levels.BackgroundPoor oral health is widespread in care-dependent older people, but no consensus for a minimum standard of oral health care exists yet.MethodsThe e-Delphi approach was applied to a selected panel of interdisciplinary experts. Data analysis was based on three measurements: (a) ≥70% of experts’ opinion fall into category “agree or strongly agree,” (b) median score on the 5-point Likert scale ≥4, (c) interquartile range ≤1.ResultsA total of 31 experts from 17 European countries participated in this survey. Agreement was achieved for a compulsory dent…
Trasplante de membrana amniotica en la reconstrucción de superficie ocular.
2004
Las indicaciones del empleo de placenta para el tratamiento de patología oftálmica están reevaluándose y redefiniéndose.Esta tesis ha desarrollado su investigación en una doble vertiente, una experimental y otra clínica, para valorar la utilidad de la membrana amniótica en la reconstrucción de la superficie ocular. En la primera parte, se ha aplicado un modelo experimental de causticación corneal con compromiso límbico a 40 ojos de conejo albinos de la raza New Zealand, estableciéndose dos grupos de estudio (control y trasplante de membrana). La evolución espontánea de las lesiones provocadas en el grupo control es hacia la opacidad corneal, neovascularización y tendencia a la conjuntivaliz…
Current Surgical Treatment Standards for Esophageal and Esophagogastric Junction Cancer
2020
A number of different surgical techniques for the treatment of cancer of the esophagus and the esophagogastric junction have been proposed. Guidelines generally recommend a transthoracic approach for esophageal cancer, including Siewert type I tumors. In tumors of the proximal esophageal third, transthoracic esophagectomy may be extended to a three-field approach, including resection of cervical lymph nodes. However, the choice between transthoracic esophagectomy with intrathoracic anastomosis (Ivor Lewis esophagectomy) and the three-incision approach with cervical esophago-gastrostomy (McKeown esophagectomy) remains controversial, with guidelines varying among different countries. Furtherm…
Surgical robotics for esophageal cancer
2018
We present an update on robotic techniques and their advantages and use in esophageal cancer surgery. Recent work has shown tremendous progress in robotic-assisted minimally invasive esophagectomy (RAMIE) and lymphadenectomy for esophageal cancer, as well as benefits of robotic surgery in high upper esophageal tumors and T4b disease. We discuss the different RAMIE techniques, especially for intrathoracic anastomosis. The ongoing ROBOT trial had demonstrated superiority of robotic esophageal cancer surgery over open esophagectomy. There are various putative technical advantages of RAMIE over minimally invasive esophagectomy, which need to be proven in future trials.
