Educational interventions to integrate surgical staff within medical units during the COVID-19 pandemic: EDUCOVID survey.

BACKGROUND: The SARS-CoV-2 (COVID-19) pandemic required a rapid surge of healthcare capacity to face a growing number of critically ill patients. For this reason, a support reserve of physicians, including surgeons, were required to be reassigned to offer support. OBJECTIVE: To realize a survey on the educational programs deployed (face-to-face or e-learning focusing on infective area, basic gestures, COVID clinical management and intensive care medicine), and their impact on behavior change (Kirkpatrick 3) of the target population of surgeons, measured on a five modalities Likert scale. DESIGN: Cross-sectional online e-survey (NCT04732858) within surgeons from the Assistance Publique - Hôpitaux de Paris network, metropolitan area of Paris, France. RESULTS: Cross-sectional e-Survey: among 382 surgeons invited, 37 (9.7%) participated. The effectiveness of the educational interventions on behavior changes was rated within the highest region of the Likert scale by 15% (n = 3) and 22% (n = 6) for 'e-learning' and 'face-to-face' delivery modes, respectively. CONCLUSIONS: Despite the low response rate, this survey suggests an overall low impact on behaviour change among responders affiliated to a surgical discipline.

Opiorphin levels in fluids of burning mouth syndrome patients: a case-control study.

OBJECTIVES: Idiopathic Burning mouth syndrome (iBMS) is a poorly understood affection characterized by persistent pain in the oral cavity without any clinical or biological abnormality. Opiorphin is a natural inhibitor of enkephalin-inactivating ectopeptidases, mainly produced by salivary glands, that has demonstrated analgesic properties. The objective of the present case-control study was to test the hypothesis of a decrease in opiorphin levels in iBMS patients. MATERIALS AND METHODS: Twenty-one iBMS patients and 21 matched controls subjects were included between 2011 and 2013. Submandibular and sublingual salivary, blood, and urinary opiorphin levels of iBMS patients were compared to controls. RESULTS: Results are expressed as mean values ± SD and compared using the Wilcoxon Signed Rank test. Correlations were analyzed with Spearman coefficient. The level of significance was fixed at p < 0.05. Opiorphin levels in iBMS and controls were respectively (in ng/ml) in basal saliva: 37.8 ± 42.5 and 67.6 ± 188.9 (p = NS); stimulated saliva: 28.8 ± 25.3 and 31.1 ± 29.1 (p = NS); blood: 4.6 ± 5.4 and 1.9 ± 1.4 (p < 0.05); and urines: 68.5 ± 259.8 and 8.9 ± 6.2 (p = NS). CLINICAL RELEVANCE: In conclusion, the lack of significative difference in salivary opiorphin levels between iBMS and controls does not favor a direct local role for opiorphin in the etiopathogeny of iBMS. However, higher blood opiorphin levels may reflect a systemic dysregulation in iBMS. Trial registration NCT02686359 https://clinicaltrials.gov/ct2/show/NCT02686359.

Phase III, randomized, double-blind, placebo-controlled trial of topical 2 % lidocaine for the prevention and treatment of oral mucosal pain in children.

OBJECTIVES: The aim of this study was to assess the efficacy in pain reduction of topical 2 % lidocaine compared to a placebo cream in children with oral mucosal lesions due to trauma or aphthous ulcers or in the prevention of clamp placement pain. MATERIALS AND METHODS: The design was a double-blind, randomized, placebo-controlled, four-center trial on 64 patients. Pain intensity and relief were measured using a 100-mm visual analog scale (VAS). One-tailed Student's t test and ANOVA were used for statistical analyses. RESULTS: Independent of the pain origin, application of 2 % lidocaine cream led to a mean reduction in VAS pain intensity of 19.7 mm ± 18.3, which was significantly greater than that obtained with the placebo cream (p = .025). Analyses showed a statistically significant efficacy of the 2 % lidocaine cream (p < .0001). Its efficacy was not associated to any local or systemic adverse drug reaction, as reported by the patients. As the most important population represented in our patients was children whom a rubber dam clamp was placed, we also specifically analysed this population, and we were able to demonstrate a significantly greater efficacy of the 2 % lidocaine cream on the pain caused by the rubber dam clamp placement in comparison to the placebo cream (p < .005). CONCLUSIONS: A significant reduction in pain intensity occurred after application of 2 % lidocaine cream, and the effect was significantly greater than that obtained with the placebo cream. Considering the study's limitations, this product appears safe for use in children. CLINICAL RELEVANCE: For painful benign lesions of the oral mucosa (trauma or aphthous ulcers) or for preventing painful iatrogenic procedures such as rubber dam clamp placement, it is essential to treat or prevent pain onset, especially in the pediatric population for whom a painful experience could end in refusal of dental care. Application of a topical anesthetic in this specific situation is of particular interest, as is defining its efficacy and safety.

Oral Lichen Planus in Patients With Good's Syndrome: A Literature Review.

Good's syndrome is defined as the association of a thymoma with an immune deficiency. Many patients with Good's syndrome also have oral lichen planus involvement, and some authors have even considered it to be one of the clinical signs of Good's syndrome. In the literature, to our knowledge, clinical forms of oral lichen planus associated with Good's syndrome have not been described. We therefore aimed to characterize the forms of oral lichen planus occurring in the context of Good's syndrome. To this end, we carried out a scoping review of the literature according to the Joanna Briggs Institute guide and included 17 articles on the theme of "the forms and clinical locations of oral lichen planus associated with Good's syndrome". A total of 17 articles were selected, and 19 patients with Good's syndrome including oral lichen planus were identified. Most of them were women aged 60 years with erosive oral lichen planus of the tongue and inner cheeks. The treatments used were thymectomy, to which immunoglobulin infusions were added in some cases. All these treatments resulted in improvement of the oral lichen planus in 70.6% of cases. The management of Good's syndrome allows the improvement of oral lichen. In patients over 50 years of age with acute erosive oral lichen planus refractory to conventional therapies, Good's syndrome should be investigated.

[Oral cavity as a target and a marker of environmental exposures: diseases diagnosed during adulthood]. / La sphère orale, cible et marqueur de l'exposition environnementale - II. Maladies diagnostiquées chez l'adulte.

The oral cavity is one of the main route for environmental contaminations associated to many chronic diseases via alimentation, medications and respiration. Other factors may also impact the oral environment, some of them are endogenous, like microbiota, hormones and saliva, and others are exogenous, like dental materials and pathogens.

TITLE: La sphère orale, cible et marqueur de l'exposition environnementale - II. Maladies diagnostiquées chez l'adulte. ABSTRACT: La cavité buccale est l'une des voies majeures des contaminations environnementales connues pour être impliquées dans de nombreuses maladies chroniques via l'alimentation, les médications ou même la respiration. D'autres facteurs peuvent également influer sur l'environnement oral, certains endogènes, comme le microbiote, les variations hormonales, la salive, d'autres exogènes, comme les biomatériaux dentaires et les agents pathogènes. Cette synthèse fait le point sur l'état des connaissances, les questions et controverses sur les facteurs environnementaux courants au contact de la sphère orale impliqués dans les maladies de la cavité orale diagnostiquées chez l'adulte telles que les cancers des voies aéro-digestives supérieures, les ostéonécroses des mâchoires, et les parodontites, ces dernières pouvant d'ailleurs être directement liées à des pathologies systémiques comme les accidents vasculaires cérébraux, la maladie d'Alzheimer ou la maladie de Crohn notamment. La caractérisation des impacts environnementaux sur le microbiote oral, la salive, l'émail dentaire peut servir de marqueur pronostic précoce des maladies diagnostiquées ultérieurement, en lien avec ces expositions.

Clinical study evaluating the effect of bevacizumab on the severity of zoledronic acid-related osteonecrosis of the jaw in cancer patients.

This study aimed to evaluate the effect of bevacizumab (BVZ) on the severity of osteonecrosis of the jaw (ONJ) in a cohort of cancer patients treated with intravenous zoledronic acid (ZA). We reviewed 42 oncologic patients with ONJ between 2007 and 2010. Only patients with solids tumors and who had received ZA were included. Data analyses included age, sex, underlying disease, ZA and BVZ dosages, dental history and ONJ characteristics. Of the 42 ONJ patients treated with ZA, 10 also received BVZ. In the 10 ZA/BVZ patients, the mean duration of ZA treatment at the time of ONJ diagnosis was 12.4 months (±6.8), compared to 22.9 months (±4.8) in the 32 patients who received ZA only (p<0.05). Cox's model analysis of the delay to ONJ diagnosis confirmed the impact of BVZ on ONJ diagnosis. In the ZA/BVZ-treated group, 7 (70%) patients developed spontaneous osteonecrosis. Multiple logistic regression analysis showed that ZA/BVZ is associated with increased risk of developing spontaneous ONJ (OR 6.07; 95% CI, [1.3-28.2], p<0.05). And finally, the number of ONJ lesions was increased in the ZA/BVZ-treated group compared to the ZA group (p<0.01). Other clinical conditions as type of tumor (prostate, breast…), cancer severity or other chemotherapy drugs also could be involved in ONJ evolution. However, this study demonstrates for the first time the potential negative influence of BVZ on the incidence and severity of ONJ in patients receiving ZA. Within the study limits, our results suggest that combination ZA/BVZ treatment may possibly predispose to the development of spontaneous and earlier ONJ.

Osteonecrosis of the jaw and nonmalignant disease: is there an association with rheumatoid arthritis?

OBJECTIVE: To review cases of bisphosphonate-related osteonecrosis of the jaw (BRONJ) occurring in association with benign disease and to describe and compare the clinical course and outcome for patients with BRONJ and rheumatoid arthritis (RA) or osteoporosis. METHODS: We retrospectively reviewed observations of all patients referred for treatment and followup for BRONJ from January 2007 to December 2011. Only patients with malignant disease were excluded. Demographic data, medical history, maxillofacial findings, BRONJ treatment, and followup were reviewed for each case. RESULTS: Over a 5-year period, we diagnosed 112 patients with BRONJ. Among these patients, 15 received bisphosphonate (BP) treatment for nonmalignant disease (mean age 65.7 ± 19.8 yrs, 80% women). Patients received BP for a variety of reasons: 8 (53%) to prevent osteoporosis in association with underlying RA; 6 (40%) to prevent idiopathic osteoporosis; and 1 (7%) to treat ankle algodystrophy. The mean oral BP exposure period was 48.4 months (median 36 mo). In 13 cases (86.6%), BRONJ was diagnosed following dental extraction. Of the 8 patients with RA, 5 (62.5%) were taking prednisone at the time of the discovery of BRONJ. Major surgery, sequestrectomy, or alveolectomy was performed in 9 patients (60%), all of whom healed within 3 to 36 months (mean 11.5 mo). Comparative analysis of all the variables showed no statistically significant differences between patients with RA and others. CONCLUSION: ONJ is a rare adverse effect of BP therapy, especially when administered orally. Within the limits of our study, we were unable to demonstrate a difference in BRONJ disease spectrum, clinical course, or outcome between patients with and those without RA.
