[Oral cavity cancer: A distinct entity]. / Le cancer de la cavité orale : une entité spécifique ?

Oral Squamous cell carcinoma represent the 17th most frequent cancer in the world. The main risk factors are alcohol and tobacco consumption but dietary, familial, genetic, or oral diseases may be involved in oral carcinogenesis. Diagnosis is made on biopsy, but detection remains late, leading to a poor prognosis. New technologies could reduce these delays, notably Artificial Intelligence and the quantitative evaluation of salivary biological markers. Currently, management of oral cancer consists in surgery, which can be mutilating despite possible reconstructions. In the future, immunotherapies could become a therapeutic alternative and the immune microenvironment could constitute a source of prognostic markers.

Title: Le cancer de la cavité orale : une entité spécifique ? Abstract: Les carcinomes épidermoïdes de la cavité orale sont le 17e cancer le plus fréquent dans le monde. Les facteurs de risque principaux sont l'alcool et le tabac mais des facteurs alimentaires, familiaux, génétiques ou certaines maladies orales peuvent intervenir dans la genèse de ces cancers. Le diagnostic est tardif, entraînant un pronostic sombre. De nouvelles approches, comme l'utilisation de l'intelligence artificielle ou de marqueurs biologiques salivaires pourraient réduire ces délais. La prise en charge actuelle de ces cancers repose sur la chirurgie, la chimiothérapie et la radiothérapie, mais avec une iatrogénie importante. Les immunothérapies pourraient devenir une alternative à ces traitements et certaines caractéristiques du microenvironnement immunitaire pourraient constituer un/des marqueurs pronostiques.

Laser Hair Removal for Intraoral Flaps: A Review.

Importance: Laser hair removal is a noninvasive technique that has been used for patients with oropharyngolaryngeal hair growth related to surgical flap reconstruction after head and neck cancer resection. The purpose of this work was to perform a rapid review of the literature to determine the therapeutic relevance of laser hair removal and identify laser parameters. Observations: A total of 10 publications addressing depilation of the head and neck sphere were selected and analyzed. Conclusions and Relevance: Laser therapy appears to be a promising treatment for hair removal from flaps with few side effects. However, there is no scientific basis for a standardized protocol or determination of the superiority of laser hair removal over another treatment.

Relationship between internet research data of oral neoplasms and public health programs in the European Union.

BACKGROUND: Tobacco and alcohol are the main risk factors for oral squamous cell carcinoma, the low survival rate of which is a public health problem. European-wide health policies (a prevention campaign, tobacco packaging) have been put in place to inform the population of the risks associated with consumption. Due to the increase in smoking among women, the incidence of this disease remains high. The identification of internet research data on the population could help to measure the impact of and better position these preventive measures. The objective was to analyze a potential temporal association between public health programs and interest in oral cancers on the internet in the European Union (EU). METHODS: A search of data from Google ©, Wikipedia © and Twitter © users in 28 European countries relating to oral cancer between 2004 and 2019 was completed. Bibliometric analysis of press and scientific articles over the same period was also performed. The association between these data and the introduction of public health programs in Europe was studied. RESULTS: There was a temporal association between changes in tobacco packaging and a significant increase in internet searches for oral cancer in seven countries. Unlike national policies and ad campaigns, the European awareness program Make Sense has had no influence on internet research. There was an asymmetric correlation in internet searches between publications on oral cancer from scientific articles or "traditional" media (weak association) and those from internet media such as Twitter © or Wikipedia © (strong association). CONCLUSION: Our work highlights seven areas around which oral cancer awareness in Europe could be refocused, such as a change in the communication of health warnings on cigarette packs, the establishment of a more explicit campaign name regarding oral cancer, the involvement of public figures and associations in initiatives to be organized at the local level and the strengthening of awareness of the dangers of tobacco in the development of oral cancer.

Geographic stomatitis with palate involvement.

Benign migratory glossitis or geographic tongue is a benign condition that usually manifests as asymptomatic erythematous and migratory circinate patches, involving the lateral and dorsal aspects of the tongue. Extra-lingual lesions uncommonly occur and are mainly located on labial and buccal mucosae, lips and floor of the mouth. The present report describes one patient with a geographic lesion on the hard palate associated with lingual lesions and another patient who had multiple geographic lesions both in the hard and soft palate without lingual lesions. We found 64 cases in the English literature of ectopic locations with 22 palate involvement. No case of simultaneous involvement of the hard and the soft palate was found.

Implications of endodontic-related sinus aspergillosis in a patient treated by infliximab: a case report.

INTRODUCTION: Sinus aspergillosis is a potential complication after root canal therapy of antral teeth. Indeed, zinc oxide-eugenol cement overfilling in the sinus may promote fungal infection. Moreover, if sinus aspergillosis triggers chronic sinusitis with aspergilloma, it may also lead to invasive phenomena, especially for immunocompromised patients. METHODS: We reported a sinus aspergillosis case of a patient treated with infliximab (Remicade; Janssen Biologics BV, Leiden, Netherlands). The purpose of this article was to explore the mechanisms of this pathosis, especially the impact of the root canal sealer overextension, which is a contributing factor for fungal infection. The surgical management and the follow-up are also described. RESULTS: Six months after surgery, the patient showed no clinical signs and presented with a healthy and airy right maxillary sinus on the computed tomography scan. CONCLUSIONS: In conclusion, prevention and screening of aspergillosis of maxillary sinus may be considered before starting an anti-tumor necrosis factor alpha therapy.
