Ingestion of Multiple Magnets by Children: Diagnosis and Management When Ingestion is not Witnessed.
Ann Ital Chir
December 2024
General and Thoracic Pediatric Surgery Unit, Bambino Gesù Children's Hospital, IRCCS, 00165 Rome, Italy.
Aim: Foreign body ingestion, particularly that of magnets, is a significant issue for children aged 6 months to 3 years due to their prevalence in toys and household items. Most ingested foreign bodies pass naturally, but 10%-20% of such cases require endoscopic removal, and <1% require surgery.
Case Presentation: A 2-year-old girl presented with abdominal pain, nausea, and vomiting.

To evaluate dual-layer dual-energy computed tomography (dlDECT)-based characterization of thrombus composition for differentiation of acute pulmonary embolism (PE) and chronic thromboembolic pulmonary hypertension (CTEPH). This retrospective single center cohort study included 49 patients with acute PE and 33 patients with CTEPH who underwent CT pulmonary angiography on a dlDECT from 06/2016 to 06/2022. Conventional images), material specific images (virtual non-contrast [VNC], iodine density overlay [IDO], electron density [ED]), and virtual monoenergetic images (VMI) were analyzed.

Non-small cell lung cancer (NSCLC) is a major subtype of lung cancer and poses a serious threat to human health. Due to the advances in lung cancer screening, more and more clinical T1 NSCLC defined as a tumor with a maximum diameter of 3cm surrounded by lung tissue or visceral pleura have been detected and have achieved favorable treatment outcomes, greatly improving the prognosis of NSCLC patients. However, the preoperative lymph node staging and intraoperative lymph node dissection patterns of operable clinical T1 NSCLC are still subject to much disagreement, as well as the heterogeneity between primary tumors and metastatic lymph nodes poses a challenge in designing effective treatment strategies.

Black phosphorus nanomaterials (BPNM) exhibit excellent properties and potential applications in electronics, but workers may face inhalation exposure during BPNM production. In addition, there is a lack of biosafety assessments regarding respiratory exposure to BPNM of different sizes. In this study, we investigated the lung toxicity in mice exposed to 5, 50, 500 μg/kg of black phosphorus quantum dots (BPQDs) and black phosphorus nanosheet (BPNS) via single tracheal instillation.

Department of Pulmonary Medicine, Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER), Dhanvantari Nagar, Puducherry, India.
Background: The estimated incidence of pulmonary embolism (PE) is around 60-70 cases per 100,000 people annually. The overall mortality rate for massive PE is substantial, ranging from 18% to 65%. We can utilise changes in lung perfusion to stratify patients with PE acutely based on risk, highlighting its diagnostic and prognostic value.
