Leukocyte- and platelet-rich fibrin does not provide any additional benefit for tooth extraction in head and neck cancer patients post-radiotherapy :…
2020
Background One of the most important complications of radiotherapy (RT) for head and neck cancer (HNC) is osteoradionecrosis (ORN) of the jaws, arising mainly from tooth extractions. Thus, the present study aimed to evaluate the efficacy of leukocyte- and platelet-rich fibrin (L-PRF) in preventing ORN following tooth extraction in post-irradiated HNC patients, as well as other postoperative complications. Material and Methods 23 patients previously submitted to conventionally fractionated 3D-conformational RT for HNC underwent atraumatic tooth extractions with perioperative antibiotic therapy. Besides, they were randomly assigned to receive L-PRF clots to fill and cover the extraction socke…
Therapeutic management of the odontogenic keratocyst. An energetic approach with a conservative perspective and review of the current therapeutic opt…
2020
Background Odontogenic keratocysts (OKC) are cystic lesions appearing in the jaws, usually asymptomatic with a progressive growth into the bone. Many of them are diagnosed by a routine radiological examination. Material and methods This study reports a 12-year-old girl that presented an asymptomatic large radiolucent unilocular lesion associated to the crown of 3.8 that caused displacement of the molar and the inferior alveolar canal. Differential diagnosis included OKC, unicystic ameloblastoma, ameloblastic fibroma, dentigerous cyst and orthokeratinized odontogenic cyst. Two surgical interventions were performed; first, a marsupialization, and 10 months after, the third molar extraction pl…
Replacement Therapy for Surgery in FVII Deficiency: The Ster Experience Concerning 63 Interventions.
2009
Abstract Abstract 1290 Poster Board I-312 Background Excessive bleeding represents a major complication of surgical interventions, and its control is especially relevant in patients with Congenital Bleeding Disorders. In FVII deficiency, scanty data is available in surgery to guide treatment strategies. Methods The STER (Seven Treatment Evaluation Registry) is a multi-centre, prospective, observational, web-based registry providing the frame for an extensive and structured data collection. Results As of Dec. 2008, sixty-three surgical operations (36 “major” and 27 “minor”) were performed in 54 subjects (29 females and 25 males) with a FVII deficiency (31 previously symptomatic; 9 with FVIIc…
ECG Analysis for Ventricular Fibrillation Detection Using a Boltzmann Network
2015
Arrhythmias consist on electrical alterations in the heart beat control. They can be identified by means of surface ECG leads. The main goal of this work is to provide a signal classification based on ECG signal waveform in the time-frequency domain especially targeted to Ventricular Fibrillation detection. The use of a classifier based on a Boltzmann network is proposed. However, a previous signal preprocessing is also required so that the Boltzmann network is fed with the appropriate data. In this case, an R-wave detector is used; after that, the Pseudo Wigner-Ville time-frequency distribution is obtained. This distribution is used to train and test the network, which handles it as an ima…
Osteonecrosis of jaw (onj): impact of italian patients, and role of italian physicians, dentists, and researchers in the growing evidence of a “new” …
2012
Purpose: Osteonecrosis of jaw (ONJ) is an uncommon but severe complication observed mostly in patients treated with bisphosphonates (BPs) for bone metastases, myeloma, osteoporosis (so called BRONJ, Bisphosphonate-Related Osteonecrosis of Jaw), but also with other drugs (bevacizumab, sunitinib, denosumab). The number of cases observed in Italy appears high in comparison with other countries and we present a review of several aspects of ONJ in Italy and the role of Italian health professionals and researchers on increasing knowledge and adequate reporting of ONJ phenomenon; Methods: Literature review about osteonecrosis of jaw (ONJ) with selection of Italian authors and publications, on year…
Postoperative Lens Position Preoperatively Determined by Scheimpflug Photography
1999
The position of the artificial lens has an important influence on refractive power calculation. We compared the position of the crystalline lens with that of the artificial lens after cataract surgery by means of Scheimpflug photography. A difference in position of approximately 0.8 mm in the anterior direction could be determined.
Clinical management of alveolar osteitis. A systematic review
2021
Background Alveolar Osteitis (AO) is one of the most common complications of tooth extraction. Several therapeutic interventions have been described for the treatment of AO, however, there are no treatment standardized protocols. The aim of this study was to conduct a systematic review on the efficacy in pain control of the different treatments for AO. The feasibility of the application of these interventions is also discussed. Material and Methods A structured electronic and hand search strategy was applied to PubMed, Scopus, Cochrane Library, OpenGrey, and Google Scholar between January 2010 and July 2020 to identify studies according to PRISMA guidelines. The inclusion criteria were orig…

Analysis of the antibiotic prophylaxis prescribed by Spanish oral surgeons
2009
Aim: To identify prophylactic antibiotic prescription practices among Spanish dentists with preferential dedication to Oral Surgery in different types of tooth extraction surgeries. Method: Members of the Spanish Oral Surgery Society were surveyed on antibiotic prophylaxis use in 4 different tooth extraction modalities scaled according to their surgical invasiveness. Results: Sixty-nine of the 105 distributed questionnaires were returned completed. Thirteen percent of the surveyed surgeons would prescribe antibiotics to prevent postoperative wound infection when confronted with conventional tooth extraction lasting less than 5 minutes. In the case of surgery lasting more than 5 minutes, the…
Analytical parameters and vital signs in patients subjected to dental extraction.
2017
BACKGROUND: Dental consultation may provoke stress to the patient, especially when a dental surgery is going to be performed, stressful situations can cause a reaction in the sympathetic nervous system that could lead to cardiovascular alterations. Blood pressure and cardiac frequency are used often as an indirect measurement and this parameters combined can serve as good indicators of stress. Objective: Analyze the changes in vital signs and analytical parameters induced by a dental extraction. MATERIAL AND METHODS: 24 healthy patients who required a simple dental extraction underwent to a blood test and motorization of their pre- and post-extraction vital signs before, at 2 and 48 hours a…
