Dermoid cysts are embryological derivatives from soft tissues. They result from an ectodermic inclusion in the mesoderm, during the early embryonic development. These cysts have a slow development and are mostly encountered in the pediatric population. Eighty percent of them are located in the head and neck area, and most of them are on the frontozygomatic suture. They are superficial or deep on clinical examination. The diagnosis is mostly easy, sometimes with the help of radiological examination. The confirmation is histological. Surgical removed by an open approach, without cyst rupture is the gold standard treatment., (Copyright © 2024 Elsevier Masson SAS. All rights reserved.)

Background and Aims: Patients chronically infected with hepatitis B virus (HBV) are at high risk of liver fibrosis, cirrhosis and liver cancer, despite recent therapeutic advances. It is therefore crucial to find non-pharmaceutical options for liver fibrosis prevention in this population. Using cross-sectional data from the ANRS CO22 Hepather cohort, we aimed to identify socio-demographic and modifiable risk factors for significant fibrosis in chronic HBV patients., Methods: Logistic regression or Firth's penalized maximum likelihood logistic regression (according to outcome prevalence) multivariable models were used to test for associations between explanatory variables and significant fibrosis, as assessed by three non-invasive markers: aspartate aminotransferase to platelet ratio index (APRI), FIB-4, and gamma glutamyltransferase to platelet ratio (GPR). Analyses were stratified by HBV treatment status., Results: The study population comprised 2065 untreated and 1727 treated chronic HBV patients. Elevated coffee consumption was consistently associated with a lower risk of elevated fibrosis biomarkers in all three treated-participant models, suggesting a dose-response relationship (adjusted odds ratios for ≥3 cups/day versus 0 cups/day: 0.16, 0.35 and 0.62, p ≤ 0.002, according to APRI, FIB-4 and GPR, respectively). Other modifiable risk factors included tobacco and alcohol use., Conclusion: Elevated coffee consumption was consistently associated with a lower risk of significant liver fibrosis, as assessed by three non-invasive markers in treated chronic HBV patients. This result can be immediately used in real-world situations, as increasing coffee consumption may be beneficial for patients at risk of advanced liver disease., Competing Interests: Conflict of interest Stanislas Pol has served as a speaker, a consultant and an advisory board member for Janssen, Gilead, Roche, MSD, Abbvie, Biotest, Shinogi, Vivv, and LFB.

Background: Dietary guidelines are designed to help meet nutritional requirements, but they do not explicitly or quantitatively account for food contaminant exposures., Objective: In this study, we aimed to test whether dietary changes needed to achieve nutritional adequacy were compatible with acceptable exposure to food contaminants., Methods: Data from the French national dietary survey were linked with food contaminant data from the French Total Diet Study to estimate the mean intake of 204 representative food items and mean exposure to 27 contaminants, including pesticides, heavy metals, mycotoxins, nondioxin-like polychlorinated biphenyls (NDL-PCBs) and dioxin-like compounds. For each sex, 2 modeled diets that departed the least from the observed diet were designed: 1) a diet respecting only nutritional recommendations (NUT model), and 2) a diet that met nutritional recommendations without exceeding Toxicological Reference Values (TRVs) and observed contaminant exposures (NUTOX model). Food, nutrient, and contaminant contents in observed diets and NUT and NUTOX diets were compared with the use of paired t tests., Results: Mean observed diets did not meet all nutritional recommendations, but no contaminant was over 48% of its TRV. Achieving all the nutrient recommendations through the NUT model mainly required increases in fruit, vegetable, and fish intake and decreases in meat, cheese, and animal fat intake. These changes were associated with significantly increased dietary exposure to some contaminants, but without exceeding 57% of TRVs. The highest increases were found for NDL-PCBs (from 26% to 57% of TRV for women). Reaching nutritional adequacy without exceeding observed contaminant exposure (NUTOX model) was possible but required further departure from observed food quantities., Conclusions: Based on a broad range of nutrients and contaminants, this first assessment of compatibility between nutritional adequacy and toxicological exposure showed that reaching nutritional adequacy might increase exposure to food contaminants, but within tolerable levels. However, there are some food combinations that can meet nutritional recommendations without exceeding observed exposures., (© 2016 American Society for Nutrition.)

This study is focused on the composition and the evolution of tungstate ions solutions as a function of pH and increasing concentrations. The Raman analysis showed that, during the titration of the tungstate solutions, WO4(2-), HWO4- ions and probably W2O7(2-) , HW2O7(2-) and H2W2O7 solvated species could exist in aqueous solutions. For diluted solutions, additions of a strong acid does not cause any precipitation, whereas the formation of the unstable solid tungstic acid (H2WO4 or WO3.H2O) could occur in concentrated solutions.
