Exéresis de las lesiones hiperplásicas de la cavidad bucal: estudio retrospectivo de 128 casos
2005
Objetivos: Este trabajo pretende, en base a nuestra experiencia, valorar y discutir las indicaciones, ventajas e inconvenientes de la exéresis de los épulis de la cavidad bucal con el láser de dióxido de carbono (CO2) respecto al láser de Erbio:YAG (Er: YAG), el láser de diodo y el bisturí frío. Material y método: Se ha realizado un estudio retrospectivo de un grupo de 120 pacientes en los que se extirparon 128 épulis con el láser de CO2, láser de Er:YAG, láser de diodo y bisturí frío. Se realizaron controles postoperatorios a los 7, 15 y 30 días para comprobar la cicatrización y la evolución de la herida y a los 3, 6 y 12 meses verificando si se había producido o no la recidiva de la lesió…
Photobiomodulation therapy and endodontic treatment of teeth with apical periodontitis using 940-nm diode laser. Report of two cases
2022
Background: Diode laser (DL) can be used in endodontics both for its bactericidal effect inside the root canal system (RCS) and for photobiomodulation therapy (PBMT) to accelerate the repair of periradicular bone tissue. Clinical Cases: This work presents two cases of pulp necrosis/asymptomatic apical periodontitis (AAP) that were treated with 940-nm DL, administered both to disinfect the root canal and to apply PBMT to the periradicular tissues. The cases were analysed by Cone-Beam Computed Tomography (CBCT). Discussion: DL has become widely accepted due to its high antimicrobial effectiveness and its ability to accelerate the repair of large apical lesions by biostimulation. Nevertheless,…
In vitro evaluation of the temperature increment at the external root surface after Er,Cr:YSGG laser irradiation of the root canal
2009
Objectives. A study was made to determine the temperature increment at the dental root surface following Er,Cr:YSGG laser irradiation of the root canal. Design. Human canines and incisors previously instrumented to K file number ISO 30 were used. Irradiation was carried out with glass fiber endodontic tips measuring 200 µm in diameter and especially designed for insertion in the root canal. The teeth were irradiated at 1 and 2 W for 30 seconds, without water spraying or air, and applying a continuous circular movement (approximately 2 mm/sec.) in the apico-coronal direction. Results. At the 1 W power setting, the mean temperature increment was 3.84ºC versus 5.01ºC at 2 W. In all cases the d…

Low-level laser therapy in patients with Burning Mouth Syndrome : a double-blind, randomized, controlled clinical trial
2019
Background Evaluate the effect of LLLT in the treatment of burning mouth syndrome (BMS). Material and methods Twenty-one BMS patients were randomly assigned to two groups: 12 in the laser group (LG) and 9 in the control group (CG). Patients in the LG underwent 2-week sessions of LLLT for 4 weeks. The spot tip area of this tool is 0.088cm2, semi-conductor GaAlAs, with a wavelength of 808nm ±5nm (infrared), 200 mW output power, 1.97W/cm2 of power density, 3 J energy per point and application time 15 seconds per point. LLLT was applied punctually, in continuous emissions, on each of the sites where there was a symptom. Symptoms were evaluated with a visual analogue scale (VAS) and patient psyc…
The relationship between the incidence of winners/errors and the time spent in different areas of the court in elite tennis
2013
Martinez-Gallego R, Guzman JF, James N, Ramon-Llin J, Crespo M, Vuckovic G. The relationship between the incidence of winners/errors and the time spent in different areas of the court in elite tennis. J. Hum. Sport Exerc. Vol. 8, No. Proc3, pp. S601-S607, 2013. Winners and errors have been two of the most studied performance indicators in tennis, contributing to the prediction of match outcome and definition of the playing style of the players. Furthermore, the position occupied by the player on the court has also been shown to be a good indicator of both the final result and style of play. The aim of this study was to examine whether there were differences between game winners and losers i…
Discretionary vs nondiscretionary in fiscal mechanism – non-automatic fiscal stabilisers vs automatic fiscal stabilisers
2015
The goal of the present study is to increase the intelligibility of macroeconomic phenomena triggered by governmental intervention in economy by means of fiscal policies. During cyclical movements, fiscal policy can play an important role in order to help stabilise the economy. But discretionary policy usually implies implementation lags and is not automatically reversed when economic conditions change. In contrast, automatic fiscal stabilisers (SFA) ensure a prompter, and self-correcting fiscal response. The present study aims to tackle the topic of discretionary vs nondiscretionary characteristic of fiscal stabilisers (SF). In this context, the scope of the research undertaking is to laun…
Can fiscal decentralization alleviate government consumption volatility?
2016
We analyse how fiscal decentralization affects the volatility of government consumption extending the existing literature that mainly deals with the effects of the former on government size. Using data for 97 developed and developing countries from 1971 to 2010, we find that a higher degree of fiscal decentralization leads to lower government consumption volatility. This result holds for the sub-sample of advanced economies, while it is not confirmed for those less-developed. This mechanism seems to work mainly through a lower volatility of the non-discretionary spending, which typically belongs to the central government’s policy. We also confirm existing findings according to which country…
Transmission dynamics of HIV-1 subtype B in the Basque Country, Spain
2016
This work was aimed to study the HIV-1 subtype B epidemics in the Basque Country, Spain. 1727 HIV-1 subtype B sequences comprising protease and reverse transcriptase (PR/RT) coding regions, sampled between 2001 and 2008, were analyzed. 156 transmission clusters were detected by means of phylogenetic analyses. Most of them comprised less than 4 individuals and, in total, they included 441 patients. Six clusters comprised 10 or more patients and were further analyzed in order to study their origin and diversification. Four clusters included men who had unprotected homosexual sex (MSM), one group was formed by intravenous drug users (IDUs), and another included both IDUs and people infected th…
BRAF(V600E) MUTATION AND THE BIOLOGY OF PAPILLARY THYROID CANCER
2008
BRAF((V600E)) mutation is the most frequent genetic alteration in papillary thyroid carcinomas (PTCs) that are 80-90% of all thyroid cancers. We evaluated the relationship between BRAF((V600E)) and tumor, host, and environmental factors in PTCs from all geographical areas of Sicily. By PCR, BRAF((V600E)) was investigated in a series of 323 PTCs diagnosed in 2002-2005. The correlation between clinicopathological tumor, host, and environmental characteristics and the presence of BRAF((V600E)) were evaluated by both univariate and multivariate analyses. BRAF((V600E)) was found in 38.6% PTCs, with a 52% frequency in the classical PTCs and 26.4% in the tall cell variant. Univariate analysis indi…
