Lung ultrasound (LUS) has emerged as a valuable diagnostic modality for the evaluation of respiratory disorders in neonates, infants and children. LUS has high diagnostic accuracy for identification of lung lesions in neonates, infants and children, where most lung lesions abut the pleura. Furthermore, LUS has the advantage of rapid execution and ease of use, and does not require ionizing radiation. Its sensitivity, cost-effectiveness, and clinical efficiency make it an important tool for supporting clinical decision-making and improving patient management. Moreover, LUS may represent a reliable alternative to chest radiography for the assessment of pediatric lung conditions and, in selected cases, could potentially replace routine chest X-rays (CXRs). Because LUS is a user-friendly technique that enables real-time imaging without radiation, it has increasingly been used in clinical practice in recent years. Here, we discuss the diagnostic role of LUS for the accurate identification of pulmonary lesions in pediatric patients. In addition, we present LUS sonographic findings associated with common pediatric lung diseases, including signs and artifacts that can be used during diagnosis and evaluation of pediatric patients.

(1) Background: Children are susceptible to home injuries. How prepared parents were to protect their children from accidents before and during the COVID-19 quarantine is uncertain. (2) Methods: We conducted a community-based, cross-sectional study in Greece between November and December 2021. We asked parents to complete an anonymous questionnaire voluntarily. Questions focused on accident-preventive measures taken at home during the COVID-19 quarantine. (3) Results: A greater proportion of parents took protective measures for a safer home before the lockdown than during the quarantine, while an interesting percentage of parents never utilized preventive measures for their children. Slightly more than half (58.6%) of parents did not seem to worry about a possible increase in domestic accidents during the quarantine. It was observed that those who had one or two children took more protective measures than those with more than two children. Older parents seemed to explain to their children how to access emergency services more often. Mothers stayed at home with the children more often, and their education affected the presence of some of the assessed measures. In our logistic regression modeling, parental concern about accidents was more related to the incidence of an accident during the pandemic and attendance at seminars. (4) Conclusions: Although the COVID-19 lockdowns disorganized family life, parents were aware of the importance of their parenting role in creating a safe environment for children, but according to the study, there is room for improvement.

Background/Objectives: In liver transplant surgery, ischemia–reperfusion (I-R) maneuvers are frequently employed to control bleeding; however, such interventions can result in injury not only to the liver but also to remote organs. The lungs, in particular, are highly susceptible due to their extensive vascularization and inflammatory response. While pulmonary injury secondary to hepatic I-R is recognized, and despite the fact that various antioxidant compounds have been investigated for their potential to mitigate I-R-induced damage to hepatic tissue, few studies have focused on evaluating therapeutic agents aimed at mitigating lung damage in this setting. This study aimed to evaluate the protective effect of apigenin on pulmonary tissue following liver I-R injury using an experimental rat model. Methods: Sixty-three male albino Wistar rats (approximately 15 weeks old, weighing 220–350 g) were randomly allocated into three groups: a sham group (open–close surgery; n = 7), a control (C) group subjected to liver I-R injury only (n = 28), and an apigenin (Ap) group receiving intraperitoneal apigenin administration immediately after liver ischemia and prior to reperfusion (n = 28). Both the C and Ap groups were subdivided into four equal subgroups corresponding to euthanasia at 60-, 120-, 180-, and 240 min post-reperfusion. Lung tissues were harvested for immunohistochemical analysis targeting the expression of matrix metalloproteinase-3 (MMP-3) and monocyte chemoattractant protein-1 (MCP-1). Results: The apigenin-treated groups exhibited significantly reduced expression levels of MMP-3 and MCP-1 across all time points when compared to the control groups. In contrast, no expression of MMP-3 or MCP-1 was observed in the sham group. Conclusions: The findings support the protective role of the antioxidant apigenin in reducing pulmonary injury following liver I-R. The diminished expression of MMP-3 and MCP-1 in the apigenin-treated rats provides compelling evidence for its protective effects on remote organs.

Introduction: Tertiary hyperparathyroidism develops in patients who have secondary hyperparathyroidism that persists despite successful kidney transplantation or in patients who are on chronic dialysis. Aim: This study aims to present a comparison of surgical treatments of tertiary hyperparathyroidism. Materials and methods: A systematic review of studies published in English that reported on the surgical management of tertiary hyperparathyroidism was conducted using PubMed databases in accordance with the PRISMA guidelines. Two authors independently reviewed the full text of potentially selectable articles and selected appropriate studies. Surgical treatment options were evaluated. Results: This review contains thirteen relevant studies. The treatments recommended by the studies included limited parathyroidectomy, subtotal parathyroidectomy, total parathyroidectomy with autotransplantation, and total parathyroidectomy without autotransplantation. The choice of the appropriate surgical technique demands individualization of the treatment and depends mainly on the experience of the surgeon. Conclusion: The predominant treatment options appear to be subtotal parathyroidectomy and total parathyroidectomy with autotransplantation.

Background and Objectives: Inflammation and dysregulation in the intestinal barrier function in acute pancreatitis (AP) trigger pancreatic lesions, systemic inflammatory response, and multiple organ dysfunction. Eugenol, as the main component of clove (Syzygium aromaticum), is known for its antioxidant and anti-inflammatory properties. We studied the potentially beneficial effect of eugenol in a rodent model of biliopancreatic duct ligation-induced AP. Materials and Methods: Rats were randomly divided into three groups: Sham, AP, and AP + eugenol (15 mg/kg/day). Serum TNFα, IL-6, IL-18, and resistin levels, as well as IL-6, TNFα, MPO, HMGB1, and CD45 tissue expression, were determined at various timepoints after the induction of AP. Results: Eugenol attenuated hyperemia and inflammatory cell infiltration in the intestinal mucosal, submucosal, and muscular layers. IL-6 and resistin serum levels were significantly reduced in the AP + eugenol group, while serum TNFα and IL-18 levels remained unaffected overall. TNFα pancreatic and intestinal expression was attenuated by eugenol at 72 h, while IL-6 expression was affected only in the pancreas. MPO, CD45, and HMGB1 intestinal expression was significantly reduced in eugenol-treated rats. Conclusions: Eugenol managed to attenuate the inflammatory response in the intestine in duct ligation-induced AP in rats.
