Prognostic significance of BRCA1 and BRCA2 methylation status in circulating cell-free DNA of Pancreatic Cancer patients.

Introduction: Pancreatic cancer is the most fatal cancer type in the world. Its high mortality is mostly correlated to the absence of symptoms and the difficulty in early diagnosis, which in the majority of the cases occurs when the disease has already spread metastasis. Nowadays, tests that could predict early diagnosis are not available yet and the number of prognostic tests is limited. Hence, there is an urgent need for biomarkers capable of detecting early development or the rapid progression of the disease. Patients and Methods: DNA methylation represents the most frequent epigenetic event among tumor suppressor genes that are involved in various carcinogenic pathways. In the recent study we have tried to evaluate, for the first time, the prognostic value of BRCA1 and BRCA2 methylation in the cell-free DNA of pancreatic cancer patients. Using methylation-specific real-time PCR we examined the methylation status of BRCA1 and BRCA2 in 55 patients with operable and 50 patients with metastatic pancreatic cancer. In the operable disease setting, BRCA1 was found to be methylated in 33/55 (63.5%) patients examined while BRCA2 was also highly methylated in 31/55 (56.3%). In the metastatic disease, BRCA1 was found to be methylated in 26/50 (52%) while BRCA2 was found methylated in 23/50 (46%). Results: All control samples were negative for BRCA1 orBRCA2 promoter methylation. Patients with operable pancreatic cancer and a methylated BRCA1 and BRCA2 promoter status had a statistically significant poorer outcome as compared with patients with a non-methylated one (p=0.012 and p=0.001, respectively). Conclusion: In this study plasma methylation of BRCA1 and BRCA2 represents a frequent event in both the operable as well as in the metastatic setting. BRCA1 and BRCA2 methylation was significant and correlated with decreased survival in patients with operable pancreatic cancer. A larger cohort of patients is required to further explore the potential of these findings as well as to investigate whether BRCA1/2 methylation in plasma could serve as a potential prognostic biomarker in pancreatic cancer.

Parental Home Safety Practices for Domestic Accident Prevention: How Prepared Were Parents for COVID-19 Confinement? A Cross-Sectional Study.

(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.

Predicting Complicated Appendicitis in Children: Pros and Cons of a New Score Combining Clinical Signs, Laboratory Values, and Ultrasound Images (CLU Score).

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.

Hospitalization in neonatal intensive care unit: parental anxiety and satisfaction.

Introduction: the birth of an infant constitutes a challenge for all parents. Stress is intense when an infant is born prematurely or experiences health problems and enters the Neonatal Intensive Care Unit (NICU). Moreover, mothers with premature babies in the NICU would feel frustrated if they are hospitalized in the maternity clinic away from their children. The purpose of this study is to assess the stress experienced by the parents of newborns hospitalized in NICU and its correlation with their level of satisfaction from the services provided during the hospitalization. Methods: the sample consisted of 102 parents whose children were hospitalized in NICU. Parental Satisfaction questionnaires of NICU and the Picker´s institute were used. Statistical analysis was performed using χ2 (chi square) and Pearson´s correlation test (bivariate). STROBE checklist was applied. Results: out of the 102 parents, 66% were mothers and 33% were fathers. Parents expressed their satisfaction at a rate of 87.8% (±13.9%). In addition, there was strong evidence that the degree of parental satisfaction was significantly related to the age of the mother (p<0.05). The sudden noises from the alarms of the monitoring instruments were strongly correlated with the degree of parents´ satisfaction from the services provided by the NICU (p<0.05). Parents feel less stressful when their child is being monitored (p<0.05). Conclusion: the results of this study could help the staff of NICU clinics to improve parents´ satisfaction about health services. Proper and adequate communication between parents and health professionals in NICU increases parental satisfaction.

The Prognostic Value of Ultrasound Findings in Preoperatively Distinguishing between Uncomplicated and Complicated Types of Pediatric Acute Appendicitis Based on Correlation with Intraoperative and Histopathological Findings.

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.

Is It Safe to Stay at Home? Parents' Perceptions of Child Home Injuries during the COVID-19 Lockdown.

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.

Unusual extension of a dental abscess through the pterygomandibular space in subcutaneous maxillofacial tissue.

Infections of maxillary teeth commonly spread to the buccal space, whereas infections originating in the mandible usually spread to the submandibular, pterygomandibular, and buccal spaces. The pterygomandibular space may serve as a path for spread to zygomatic areas and thus must always be a part of imaging evaluations.

The Incraft stent graft for the treatment of abdominal aortic aneurysms: an iliac-friendly device with an effective conventional proximal sealing mechanism.

INTRODUCTION: The Incraft aortic stent graft (Cordis, Bridgewater, NJ, USA) is a trimodular endovascular stent graft with a conventional suprarenal active fixation specifically designed to overcome the anatomic limitation of small, stenotic, and tortuous iliac vessels. AREAS COVERED: The present article provides a complete description of the Incraft stent graft, its clinical performance, its technical characteristics as well as a comparison with other competitive endografts. EXPERT OPINION: The Incraft stent graft is an EVAR ultra low-profile device initially designed for overcoming the limitation of the hostile iliac anatomy. Recently, the device is being increasingly used in real-world conditions and not only in complex iliac anatomies with good mid-term results. Whether it remains a useful EVAR toolbox or will become a workhorse endograft is yet to be determined.

Button Sequestrum Sign Due to Osteomyelitis of the Mandible Secondary to Malignant Infantile Osteopetrosis.

The button sequestrum sign is demonstrated in a number of medical conditions and refers to a lesion of devascularised bone which is surrounded by lucency. Although it may be difficult to arrive at a single diagnosis based on this sign, the combination of clinical and paraclinical findings, patient's medical history and imagistic presentation of this sign can lead to a great specificity in chronic osteomyelitis, even if osteomyelitis is accompanied by osteopetrosis, as in the present case.

Influence of education and residence on the parental search for pediatric surgical information on the internet.

BACKGROUND: The internet is a valuable tool for access to health-related information. There is limited literature regarding its use by parents of children with surgical conditions. AIM: To investigate internet usage by parents seeking information about the surgical conditions of their offspring in relation to epidemiological factors such as family residential area and parental educational level and to subsequently review the literature regarding this topic. METHODS: An anonymous questionnaire about internet usage was completed by eligible parents of children who were admitted to our clinic for minor surgical procedures during a six-month period. RESULTS: Our results demonstrated that the internet has been mostly used by mothers for children's health information. Google was the most commonly used search engine, while pediatricians were the first parental choice for 'live' information. Only one-quarter of the parents informed their doctor about the information found online. Nine of ten parents had a positive opinion of an official website managed by the doctors of our clinic. Our results mostly agreed with the international literature. CONCLUSION: In conclusion, the establishment of official websites (designed and managed by specialists) that parents can access to receive appropriate health information is mandatory in the internet era.

An Unexpected Location of Enostosis, a Pediatric "Never Mind" Bone Lesion.

Enostoses, also known as bone islands, are common benign sclerotic bone lesion that usually represent incidental findings. They constitute a small focus of compact bone within cancellous bone. Enostoses can be seen on radiographs, CT, and MRI, and are considered one of the skeletal do not touch lesions.
