THE ROLE OF ENDOSCOPY IN ACUTE RECURRENT AND CHRONIC PANCREATITIS AND PANCREATIC CANCER
1999
Endoscopy plays an important role in the diagnosis and treatment of acute and chronic pancreatitis as well as pancreatic cancer. Sphincterotomy and stone removal in biliary pancreatitis, stone extraction and drainage in chronic pancreatitis, and stent implantation in pancreatic cancer are the predominant procedures. With endoscopy, minimal invasive techniques are at hand to solve urgent and long term problems.
NeXt for neuro-radiosurgery: A fully automatic approach for necrosis extraction in brain tumor MRI using an unsupervised machine learning technique
2017
Stereotactic neuro-radiosurgery is a well-established therapy for intracranial diseases, especially brain metastases and highly invasive cancers that are difficult to treat with conventional surgery or radiotherapy. Nowadays, magnetic resonance imaging (MRI) is the most used modality in radiation therapy for soft-tissue anatomical districts, allowing for an accurate gross tumor volume (GTV) segmentation. Investigating also necrotic material within the whole tumor has significant clinical value in treatment planning and cancer progression assessment. These pathological necrotic regions are generally characterized by hypoxia, which is implicated in several aspects of tumor development and gro…
Extractions without eliminating anticoagulant treatment: A literature review
2010
To establish whether there is a high enough risk of bleeding in patients who take oral anticoagulants, such that it would justify not using oral anticoagulants when performing a dental extraction, as well as if the reason for and anatomical location of the extraction increases such risk. Study We performed a bibliographic search in order to carry out a meta-analytic study using descriptive statistics. We compiled a sample of 1194 patients from the articles selected. Of these patients, a total of 2392 simple, serial surgical extractions were performed; none of the patients interrupted their anticoagulant treatment with warfarin sodium. Of the sample, 83 patients presented a certain degree of…
What is meant by case management for the return-to-work of workers with musculoskeletal disorders? A scoping review.
2021
BACKGROUND: Case management interventions have shown to be effective to prevent musculoskeletal pain and disability, but a single definition has not been achieved, nor an agreed profile for case managers. OBJECTIVE: To describe the elements that define case management and case managers tasks for return-to-work of workers with musculoskeletal disorders (MSDs). METHODS: A comprehensive computerized search of articles published in English until February 16, 2021 was carried out in several bibliographic databases. Grey literature was obtained through a search of 13 key websites. A peer-review screening of titles and abstracts was carried out. Full text in-depth analysis of the selected articles…
A pragmatic window of opportunity to minimise the risk of MRONJ development in individuals with osteoporosis on Denosumab therapy: a hypothesis
2021
Abstract Denosumab is associated with the development of medication-related osteonecrosis of the jaw (MRONJ), an uncommon but severe oral side effect with a higher prevalence in metastatic cancer patients than in patients with metabolic bone fragility. Although several oral triggers can initiate MRONJ, invasive oral treatments and tooth extraction still remain the most common precipitating event. In general, tooth extraction and oral surgery should be avoided in patients at increased risk of MRONJ, while extraction of non-restorable teeth should be performed based on specific risk reduction protocols to eliminate dental/periodontal infections, still protecting from MRONJ onset. Based on th…
Epidemiological evaluation of intraoperative antibiosis as a protective agent against endophthalmitis after cataract surgery.
2006
PURPOSE To evaluate risk factors for endophthalmitis after cataract surgery and to retest recent findings on the protective effect of intraoperative antibiosis and the promoting effect of the clear corneal as compared to sclerocorneal incision. DESIGN Survey study. PARTICIPANTS Five hundred thirty-eight ophthalmosurgical centers in Germany. MAIN OUTCOME MEASURE Responder specific endophthalmitis incidence. RESULTS A total of 310 (58%) questionnaires were computed resulting in an overall count of 404 356 cataract surgeries and 291 self-reported endophthalmitis cases (crude rate 0.072%). The risk of postoperative endophthalmitis for sclerocorneal versus clear corneal incisions was not signifi…
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…
