Abstract:
We report a case of a right gluteal mass from the sacroiliac joint to the knee of an infant girl. Biopsy showed histopathological features similar to infantile fibrosarcoma (IFS). However, unlike most IFS, no ETV6-NTRK3 fusion gene abnormality was detected. Molecular analysis with TruSight RNA Pan-Cancer Panel detected the presence of KIAA1549-BRAF translocation and an oncogenic NF2p.Q459* SNV with potential clinical significance. A review revealed that the combination of this patient’s tumor site with the presence of a KIAA1549-BRAF translocation abnormality and an accompanying single nucleotide variant has not been previously described. The detection of this translocation abnormality raises the possibility that the spindle cell tumors in infants with an absence of the ETV6-NTRK3 fusion gene abnormality might have a distinct pathogenetic mechanism different from the previously known IFS and congenital mesoblastic nephroma. Furthermore, the discovery of BRAF translocation and its aberrant signaling of the mitogen-activated protein kinase (MAPK) pathway in this tumor contributes to the promise of clinical benefit of using the MEKi trametinib for the treatment of progressive disease that is refractory to conventional chemotherapy.

Abstract:
Air pollution control residues (APCR) from municipal waste incinerators are usually considered as hazardous wastes because of their high contents in easily soluble Pb and other toxic metal contaminants. The objective of this research was to compare various techniques using Pb adsorption on Sphagnum peat moss (MT) for the treatment of alkaline leachates produced during the decontamination of various types of APCR including used lime (CU), electrofilter ashes (CE), and boiler ashes (CC). Regeneration tests of saturated MT using hydrochloric and sulphuric acids have revealed that excessive acid consumption (>250 kg acid/metric ton of treated APCR) are necessary for the elution of metals. However, the incineration of the saturated MT and its possible valorization represents an interesting way to explore for the management of the adsorbent. This method allows to reduce by a factor of 3 or 4 the mass of residues and increases in the same proportion the Pb content in the incinerated MT. Finally, the present study has highlighted that ion exchange on the anionic functional groups of MT would be one of the most important mechanisms implied in the Pb fixation on this natural sorbent during the treatment of very alkaline leachates (pH > 11) of APCR.Key words: lead, leaching, incinerator, air pollution control residues (APCR), removal, peat, adsorption, toxicity characteristic leaching procedure (TCLP).[Journal translation]
