Enterocyte Purge and Rapid Recovery Is a Resilience Reaction of the Gut Epithelium to Pore-Forming Toxin Attack.
2016
International audience; Besides digesting nutrients, the gut protects the host against invasion by pathogens. Enterocytes may be subjected to damage by both microbial and host defensive responses, causing their death. Here, we report a rapid epithelial response that alleviates infection stress and protects the enterocytes from the action of microbial virulence factors. Intestinal epithelia exposed to hemolysin, a pore-forming toxin secreted by Serratia marcescens, undergo an evolutionarily conserved process of thinning followed by the recovery of their initial thickness within a few hours. In response to hemolysin attack, Drosophila melanogaster enterocytes extrude most of their apical cyto…
Multifocal epithelial hyperplasia, a rare oral infection in Asia : report of twelve cases in Iran
2009
Objectives: Multifocal epithelial hyperplasia (MEH) is benign, asymptomatic oral disease with viral etiology. The frequency of this disease varies widely from one geographic region to another, and can vary, from 0.002 to 35% depending on the population studied. Study design: Here we report the clinicopathological features of twelve cases of MEH referred to Oral Medicine Department of Mashhad Dental School for the first time in Iran. Records of patients with the diagnosis of MEH in our department during 7 years were analyzed and data were extracted. Results: Most of the patients were younger than 20-year-old (66%), and females were predominantly affected (7:12). The mean age of onset was 12.…
Infezione orale da Human papillomavirus: dalla verruca al carcinoma orale. Epidemiologia, clinica, prevenzione e terapia
2015
Riasunto Obiettivi Prendere in esame l’epidemiologia e le manifestazioni cliniche dell’infezione orale da Human papillomavirus (HPV), con particolare attenzione alle lesioni con potenziale oncologico maligno. Materiali e metodi E stata condotta una revisione sistematica della letteratura finalizzata a descrivere lo stato dell’arte in merito all’infezione da HPV nella mucosa orofaringea e alle relative modalita di trasmissione del virus con particolare riferimento alla possibile contemporanea infezione in sedi anatomiche multiple. Vengono approfonditi gli aspetti riguardanti la prevenzione e il controllo dell’infezione mediante la somministrazione di vaccini e lo svolgimento di campagne cono…
Not a current fashion, but a truth since 1884
2011
We thank Kucharz [1] for the valuable historical comment to our review focusing on the role of oral infection on systemic diseases [2]. The majority of scientists today write and read the English language whereas articles in Polish and German are scarcely known outside of Poland and Germany, respectively. For these reasons, the contribution of Kaczorowsky [3] is commonly forgotten in medical literature, but the letter of Kurchaz properly acknowledges this pioneer researcher in the periodontal medicine. We also thank Blum [4] for adding his results [5,6] to our review article. As the number of references citable is limited, we did not cite the articles written by Blum et al. [5,6], but we re…
Oral Infections and the Risk of Mortality in the Iron Age
2008
Medically unattended oral abscesses may spread to their surrounding area or even throught the entire body. Depending on the individual`s constitution, such processes may lead to a life-threatening situation or death. (Pre)historic case studies deliver more information about distribution and adverse effects of oral infections and the risk of mortality. In this particular case report an iron aged skeleton of a 35- to 45-year-old woman from Eulau (Naumburg/ Saale, Germany) shows multiple periapical lesions and their effects on the viscerocranium. Furthermore, alterations on the long bones can be associated with chronic inflammation processes.
