Background: This retrospective study aimed to combine the clinical signs, laboratory values, and ultrasound images of 199 children with acute appendicitis in order to create a new predictive score for complicated appendicitis in children. Methods: The study included children who had clinical examination of abdominal pain (description of pain, anorexia, body temperature, nausea or vomiting, duration of symptoms), laboratory findings on admission (white blood cell, platelets, neutrophils, C-reactive protein), preoperative abdominal ultrasound, and histopathological report after an operation for appendicitis in their records during the period from January 2016 to February 2022. Results: According to the statistical analysis of the values using multivariate logistic regression models, the patients with appendiceal diameter ≥ 8.45 mm, no target sign appearance, appendicolith, abscess, peritonitis, neutrophils ≥ 78.95%, C-reactive protein ≥ 1.99 mg/dL, body temperature ≥ 38 °C, pain migration to right lower quadrant, and duration of symptoms < 24 h were more likely to suffer from complicated appendicitis. The new score was comprised of the 10 variables that were found statistically significant in the multivariate logistic model. Each of these variables was assigned a score of 1 due to the values that were associated with complicated appendicitis. Conclusions: A cutoff value of ≥4 has been a good indicator of the final score. The sensitivity with the usage of this score is 81.1%, the specificity 82.4%, the PPV 73.2%, the NPV approaches 88% and finally the accuracy is 81.9%. Also, the pros and cons of this score are discussed in this study.

Objective: This study compares the preoperative ultrasound findings of all children with a clinical picture of acute appendicitis on the basis of intraoperative and histopathological findings to assess the feasibility of this approach in preoperatively distinguishing between uncomplicated and complicated cases. Methods: This retrospective study includes 224 pediatric patients who underwent ultrasound prior to appendectomy at our institution between January 2016 and February 2022. Logistic regression analysis was used to investigate the association between sonographic and intraoperative histopathological findings. Results: Of the 224 participants, 61.1% were intraoperatively diagnosed with uncomplicated appendicitis (59.8% male). Multivariate logistic regression analysis revealed that patients with a higher appendiceal diameter, presence of appendicolith, and peritonitis were more likely to suffer from complicated appendicitis. Finally, the common anatomical position of the appendix and an appendiceal diameter greater than 6 mm had the highest sensitivity (94.6% and 94.5%, respectively) for predicting complicated appendicitis, with the most specific (99.3%) sonographic finding being the existence of an abscess. Conclusions: Preoperative abdominal ultrasound in children with a clinical diagnosis of acute appendicitis can distinguish between uncomplicated and complicated appendicitis in most cases of pediatric appendicitis. A higher appendiceal diameter, the presence of appendicolith, and peritonitis are parameters noted by ultrasound that strongly predict complicated appendicitis.

The COVID-19 pandemic and stay-at-home regulations have increased child home injuries. This study illustrates the type and frequency of child home injuries in Greece during the COVID-19 lockdown. Moreover, the survey reports the results on parents’ proposals regarding child injuries at home during the COVID-19 quarantine. A community-based, cross-sectional, descriptive study was conducted from November to December 2021 in Greece. Parents were asked to voluntarily complete an anonymous questionnaire, designed for the needs of the research. A statistical analysis of the data was performed using the Kolmogorov–Smirnov and Shapiro–Wilk tests for a normal distribution, a chi-squared (χ2) test to compare percentages among different groups and a non-parametric Mann–Whitney U test to determine the differences in Likert scale variables between two groups. A total of 130 parents with at least one child were questioned through an online questionnaire survey. Of the parents, 39.3%, stated that the number of accidents in their home increased. The most frequent accidents were injuries (49.3%). Most of the accidents occurred inside the house (75.8%) and were observed among children aged 0–4 years. A high percentage of children’s accidents was observed in rural/island areas or in the suburbs. Children who were with either their father or mother had one accident, and a higher number of accidents occurred when the children were with their grandparents, with the nanny or alone. For those parents who had difficulty supervising their child, child accidents increased compared to parents who had the ability to supervise. It was noticed that parents who knew how to provide a safe home stated that the number of accidents remained the same. Parents must organize a safer home. Authorities should educate parents on child injury prevention and provide them with financial facilities to provide a safer house.

Background: Hyponatremia has been identified as a marker of disease severity in various inflammatory conditions. However, its role in predicting acute complicated appendicitis (ACA) in children remains under investigation. This study evaluated the association between preoperative hyponatremia and ACA in a pediatric population. Methods: A retrospective study was conducted on pediatric patients treated for acute appendicitis in two major pediatric centers in Greece. Patients were categorized into groups based on the presence of acute uncomplicated appendicitis (AUA) and acute complicated appendicitis (ACA). Preoperative laboratory parameters were analyzed to identify potential predictors of ACA. Results: This study included 491 pediatric patients, with a mean age of 10 years. ACA patients exhibited significantly lower Na levels compared to those with AUA (136 vs. 138 mmol/L, p < 0.001). Hyponatremia (<135 mmol/L) was present in 38.4% of ACA cases compared to 2.2% of AUA cases (p < 0.001), and was associated with a significantly increased risk of ACA (OR = 18.30, p < 0.001). A sodium threshold of 135 mmol/L also demonstrated a sensitivity of 48% and a specificity of 92.1% Conclusions: Hyponatremia is a strong and specific predictor of ACA in children. When combined with other inflammatory markers, it may enhance early risk stratification, aiding in timely surgical decision making.

Background: Endotracheal tube (ETT) placement is crucial for neonates with respiratory failure. Ultrasonography (US) has emerged as a valuable tool to detect ETT positioning, competing with traditional methods. Nurses, being front-line caregivers, can perform basic ultrasound examinations. This study aimed to assess whether a nurse inexperienced in US could identify the correct ETT position in neonates after a brief ultrasound training. Methods: This study included intubated neonates hospitalized in a NICU with a postmenstrual age of under 45 weeks. A NICU nurse, following a short ultrasound training, measured the distance of the ETT tip to the right pulmonary artery and aortic arch. Chest X-rays (CXRs) confirmed the ETT position. The neonates’ ages, genders, weights, and examination times were recorded. Results: This study involved 67 neonates, including 40 (59.7%) males, with 39 (58.2%) weighing below 1500 g. The median time for correct ETT placement confirmation by CXR was 12.6 min, while US-assisted ETT recognition took 6 min initially and 5.1 min at the end of the training, which was a significant difference. No major differences were found in US distance based on the neonate’s weight and age. Gender marginally influenced US distance (β = −0.089, p = 0.056). Conclusions: The NICU nurse responded well to ultrasound training, showing results comparable with CXR. Further studies with more patients and additional studied factors are needed to fully assess US’s reliability in determining ETT positioning.

(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.
