Introduction: Actinomycosis of the larynx has been rarely reported in the literature and usually occurs in patients with a history of laryngeal carcinoma and radiation therapy. However, its co-existence with chondroradionecrosis due to radiotherapy is even rarer. The most common site of infection is the cervicofacial region, especially in the submandibular area. Case Report: Here we report a ...
Introduction: Actinomycosis is a systemic chronic bacterial infection caused by Actinomyces Israelii, an anaerobic organism normally resident in the human mouth. However, the actinomycosis of the larynx is very rare, and only about 15 cases have been reported in the literature so far. Most of the cases reported occurred in patients who had previously undergone radiotherapy for laryngeal cancer...
OBJECTIVE Our aim was to study the trend between 2007 and 2013 in the incidence of larynx cancer in a health district of 300,000 inhabitants. MATERIAL AND METHOD With information from the hospital cancer registry for the reference health area, we calculated the incidence and subsequently performed a joinpoint regression using specific software. RESULTS We found a statistically-significant d...
A tracheotomy tube, as well as the stoma through which it is inserted into the patient's throat, may represent a potential risk of fungal infections for patients suffering from larynx cancer. The study was aimed at evaluating the influence of the hospital room environment on the fungal colonisation of tracheotomy tubes in the case of patients diagnosed with larynx cancer and operated on in the ...
OBJECTIVES/HYPOTHESIS Assess tumor suppressor p53 (TP53) functional mutations in the context of other biomarkers in advanced larynx cancer. STUDY DESIGN Prospective analysis of pretreatment tumor TP53, human papillomavirus (HPV), Bcl-xL, and cyclin D1 status in stage III and IV larynx cancer patients in a clinical trial. METHODS TP53 exons 4 through 9 from 58 tumors were sequenced. Mutation...
The genetically determined capacity of the cytochrome P450 CYP2D6 is suspected to be involved in the activation of tobacco carcinogens. From a multicentric case-control study carried out to analyze the interaction between host and environmental factors on tobacco-related cancers, we reported recently that the effect of tobacco on lung cancer risk rose with increasing CYP2D6 activity, and the ef...
OBJECTIVES The objective of this work was to apply the two-stage clonal expansion model, with the intention to expand the literature on epidemiological applications of the model and demonstrate the feasibility of incorporating biologically based modelling methods into the widely used retrospective cohort study. METHODS The authors fitted the two-stage clonal expansion model model to three occ...
BACKGROUND There is convincing evidence that alcohol consumption increases the risk of cancer of the colorectum, breast, larynx, liver, esophagus, oral cavity and pharynx. Most of the data derive from studies that focused on the effect of moderate/high alcohol intakes, while little is known about light alcohol drinking (up to 1 drink/day). PATIENTS AND METHODS We evaluated the association bet...
