RESUMEN

BACKGROUND: Foreign body ingestion in children is a clinically important reason for presentation to the emergency department. The individual outcome ranges from benign spontaneous courses to severe complications. Fatal outcomes occur rarely and complications are related to patient's age as well as type and location of the foreign body. The aim of our present study was to evaluate the outcome of children and adolescents with foreign body ingestion with a focus on complications, which mainly occurred after button battery ingestion. METHODS: We reviewed medical records of patients between 0 and 18 years of age who had presented to the paediatric emergency department of our hospital with suspected foreign body ingestion between January 2011 and March 2021 (123 months). Clinical, imaging, and endoscopic data as well as treatment modalities were analysed. RESULTS: In the ten10 year period under review, a total of 1,162 children and adolescents (6 months - 18 years) presented to our emergency room with suspected foreign body ingestion. Among those, 398 ingestions (34%) could be verified radiologically and/or endoscopically, while in the remaining 764 cases (66%) the suspicion could not be confirmed. The majority of patients with verified ingestion (n=324; 81%) presented with ingestion of a metallic foreign body. We observed 55 cases with verified ingestion of a button battery. Five of these cases had severe complications, with a near-fatal course in two patients who developed an oesophageal-tracheal fistula. CONCLUSION: In contrast to all other ingestions of foreign bodies in children, button battery ingestions lead to mucosal damage and severe complications in a significant number of children.

RESUMEN

Aberrant promoter methylation of tumor relevant genes frequently occurs in early steps of carcinogenesis and during tumor progression. Epigenetic alterations could be used as potential biomarkers for early detection and for prediction of prognosis and therapy response in lung cancer. The present study quantitatively analyzed the methylation status of known and potential gatekeeper and tumor suppressor genes [O-6-methylguanine-DNA methyltransferase (MGMT), Ras association domain family member 1A (RASSF1A), Ras protein activator like 1 (RASAL1), programmed cell death 4 (PDCD4), metastasis suppressor 1 (MTSS1) and tumor suppressor candidate 3 (TUSC3)] in 42 lung cancers and in corresponding non-malignant bronchus and lung tissue using bisulfite-conversion independent methylation-quantification of endonuclease-resistant DNA (MethyQESD). Methylation status was associated with clinical and pathological parameters. No methylation was found in the promoter regions of PDCD4 and MTSS1 of either compartment. MGMT, RASSF1A and RASAL1 showed sporadic (up to 26.2%) promoter methylation. The promoter of TUSC3, however, was frequently methylated in the tumor (59.5%), benign bronchus (67.9%) and alveolar lung (31.0%) tissues from each tumor patient. The methylation status of TUSC3 was significantly associated with smaller tumor size (P=0.008) and a longer overall survival (P=0.013). Pooled blood DNA of healthy individuals did not show any methylation of either gene. Therefore, methylation of TUSC3 shows prognostic and pathobiological relevance in lung cancer. Furthermore, quantitative detection of TUSC3 promoter methylation appears to be a promising tool for early detection and prediction of prognosis in lung cancer. However, additional studies are required to confirm this finding.
