the disease. Conclusion Our study on the implication of polymorphic marker IVS6a GATT is one of the first works carried out in the Tunisian population and confirms the usefulness of this marker in the clinical expression of cystic fibrosis.The diagnosis of parasitic and fungal infections, historically based on the detection of these pathogens using direct diagnosis (macro/microscopic examination, culture) or serological methods, has considerably evolved in the last decades, especially with the development of molecular approaches and mass spectrometry. These techniques, as well as most analyses of parasitic and fungal serology, are mostly the preserve of Hospital University Centers Parasitology-Mycology laboratories. In 2016, the French association of medical parasitology and mycology teachers and hospital practitioners (Anofel) has provided a Catalogue of rare analyses, regularly updated and freely accessible on the Anofel website (https//anofel.net/). This tool, which hinges on 4 parts (parasitology, parasitic serology, mycology, and fungal serology), aims to provide information on all available analyses, and a list of hospital laboratories able to undertake them. It is complementary to the other reference works that were developed by our association, including the Guide of analyses and methods in parasitology and mycology, published in 2018, and the eANOFEL pictures and videos database, freely accessible online (http//). In this article, we draw-up a state-of-the-art of the most specialized techniques available in the parasitology-mycology laboratories and presented in the Catalogue of rare analyses of the Anofel collegium, and their interest for the diagnosis of these infections.Background and objectives The French national authority for health (Haute autorité de santé HAS) and the French clinical toxicology society (Société de toxicologie clinique STC) received a formal request from the French ministry for heath to elaborate recommendations for the screening of environmental overexposure to inorganic arsenic (iAs), for the medical management of overexposed patients and for the medical surveillance of exposed population. To allow these recommendations, preliminary literature retrieval and analysis were performed for identifying validated indicators of both exposure and early effects of iAs and their levels in the general population living in France. Methods Evaluations of inorganic arsenic toxicity conducted by national or international health agencies during the last 3 decades were all examined and analyzed. These evaluations were completed by literature retrieval through Medline and Scopus from January 2016 to December 2019. Results and conclusions The best biomonitoring indicator for iAs exposure is the sum of urine iAs, monmomethylarsonic acid (MMA) and dimethylarsinic acid (DMA) concentrations (SAs). The upper limit of confidence interval of the 95th percentile of the distribution of this parameter in the general adult population living in France is 10 μg/g of creatinine, and is recommended as the limit value for the definition of overexposure. In less than 12 year-old children specific limit values are required, but not yet available. In their absence, SAs should exceed both 10 μg/g creatinine and 11 μg/L to be considered as indicating a probable overexposure to iAs. There are no useful biological indicators of iAs early effects. Non carcinogenic skin effects of inorganic arsenic (hyperpigmentation and keratosis) should be considered as the earliest deleterious effects of repeated environmental iAs exposure.The SARS-CoV-2 virus is responsible for an epidemic disease called COVID-19, which was initially evidenced in Wuhan, China, and spread very rapidly in China and around the world. In France, the first isolated case seems now to be reported in December 2019, stage 3 of the COVID-19 epidemic was triggered on March 14th, the start of the planned containment exit from May 11th.
