Malocclusion in Elementary School Children in Beirut: Severity and Related Social/Behavioral Factors

Aim. To assess severity of malocclusion in Lebanese elementary school children and the relationship between components of malocclusion and sociodemographic and behavioral factors. Methods. Dental screening was performed on 655 school children aged 6–11 from 2 public (PB) and 5 private (PV) schools in Beirut. A calibrated examiner recorded occlusion, overjet, overbite, posterior crossbite, midline diastema, and crowding. Another examiner determined the DMFT (Decayed/Missing/Filled Teeth) score. A questionnaire filled by the parents provided data on sociodemographic and behavioral factors. Multinomial, binomial, and multiple linear regressions tested the association of these factors with occlusal indices. Results. Malocclusion was more severe in PB students. Age and sucking habit were associated with various components of malocclusion. Crowding was more prevalent among males and significantly associated with the DMFT score. Income and educational level were significantly higher (P<0.05) in PV pupils and deleterious habits were more frequent in PB children. Conclusions. Children of lower socioeconomic background had more severe malocclusions and poorer general dental health. Compared to Western and WHO norms, the findings prompt health policy suggestions to improve dental care of particularly public school children through regular screenings in schools, prevention methods when applicable, and cost effective practices through public and private enabling agencies

Hepatoblastoma in childhood, long term survival achieved: 2 case reports and literature review

Introduction: Hepatoblastoma is the most common primary liver tumor for children under 5 years of age. It usually presents as an abdominal mass, symptomatic only when large enough to cause mass effect on nearby organs. Symptoms such as early satiety, anorexia, abdominal pain or weight loss are the most common. Diagnosis depends on imaging studies, AFP levels and percutaneous biopsy. Treatment modality is usually surgical with neoadjuvant chemotherapy. Cases: In this article, we present 2 cases of hepatoblastoma treated 15 years ago by neoadjuvant chemotherapy and surgery, and are presenting for long term follow-up with complete disease remission. Discussion: Complete resection and remission can be achieved as demonstrated below by our 2 cases of hepatoblastoma, especially when performing a true anatomical hepatectomy, along with a neoadjuvant chemotherapy regimen. Although one of the cases did not respond to chemotherapy very well a complete resection was achieved and therefore a disease free survival of 15 years. Conclusion: Hepatoblastoma are rare tumors of the pediatric age group. Management depends highly on combined surgical and pediatric oncological knowledge. A complete disease remission can be achieved when both modalities are treatment are optimal. Therefore, hepatoblastoma cases should be referred to specialized centers for management

Platelet-to-lymphocyte ratio is correlated with a delay in feeding resumption following a transhiatal esophagectomy with cervical anastomosis

Introduction: The lymphocytic population, neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) are prognostic tools predictive of adverse outcomes for several solid tumors and oncologic surgeries, one of which is esophageal adenocarcinoma. Furthermore, delayed resumption of oral feeding postoperatively is associated with significant morbidity. Given the controversies regarding post-op nutritional support in these patients, this study investigates the prognostic role of the lymphocytic percentage, the NLR, and the PLR in predicting prolonged length of hospital stay (LOHS) and ICU stay (LOICUS) as well as delayed oral feeding following transhiatal esophagectomy (THE) for adenocarcinoma of the esophagogastric junction (AEG). Methods: Forty consecutive patients who underwent transhiatal esophagectomy performed by a single surgeon for Siewert type II and type III adenocarcinoma of the esophagogastric junction at a tertiary referral center were selected. Retrospective data collection was performed from the patients’ medical records, and statistical analysis was performed using Pearson correlation and Student’s t test and Chi-square testing. Results: An increased LOHS was correlated with a lower preoperative lymphocyte percentage (p = 0.043), higher NLR (p = 0.010) and PLR (p = 0.015), and an increased number of packed red blood cell (PRBC) transfusions perioperatively (p = 0.030). An increased LOICUS was correlated with a lower preoperative lymphocyte percentage (p = 0.033), higher NLR (p = 0.018) and PLR (p = 0.044), an increased number of PRBC transfusions (p = 0.001), and patients’ comorbidities (p < 0.05). A delay in feeding resumption was correlated with a lower preoperative lymphocyte percentage (p = 0.022), higher NLR (p = 0.004) and PLR (p = 0.001), an increased PRBC transfusions (p = 0.001), and diabetes mellitus (p = 0.033). Multivariate analysis with automatic linear modeling showed that only the preoperative PLR was a powerful predictor for the delay of feeding resumption (p < 0.01). Conclusion: The lymphocyte percentage, PLR, and NLR are found to be associated with prolonged hospitalization and ICU stay and delayed oral feeding following THE for Siewert types II and III AEG. We hope by this series, to have set, at least one preliminary cornerstone, in the creation of a prognostic model, capable of assessing the need for an intraoperative jejunostomy placement, in patients undergoing esophagectomy for distal esophageal carcinoma.SCOPUS: ar.jDecretOANoAutActifinfo:eu-repo/semantics/publishe

Inferior epigastric artery lymph nodes: A pathway for systemic dissemination from peritoneal carcinomatosis?

Background and Objectives: We report, for the first time in the literature, a metastatic lymphatic pathway along the inferior epigastric vessels, through the inferior epigastric lymph nodes (IELNs), in patients with peritoneal carcinomatosis (PC). Interestingly, these lymph nodes (LNs) in the anterior retroperitoneum were not detectable on preoperative imaging. They may, however, represent a pertinent systemic dissemination pathway for PC. Patients and Methods: In patients undergoing indocyanine green-fluorescence imaging during cytoreductive surgery for PC, an incidental finding of a hyperfluorescent LN, harboring metastatic tumorous cells, around the inferior epigastric artery was made. Results: In three out of five patients with clear fluorescent hotspot, the harvested LN was harboring metastatic cancerous cells. None of these nodes, whether negative or positive, was visible on any preoperative imaging modalities. A protocol to sample, in a systematic manner, the IELN in patients with PC, is currently being devised at our institution. Conclusion: These lymphatic nodes basin and channels might reveal to be a potential passage from peritoneal metastasis to the extraperitoneal lymphatic compartment, representing an independent pathway for cancerous cell dissemination. This will bring us to further investigate the prevalence and the prognostic significance of these LNs.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Prognostic value of peritoneal scar-like tissue in patients with peritoneal metastases of ovarian origin presenting for curative-intent cytoreductive surgery.

Complete cytoreductive surgery (CRS), remain the gold standard in the treatment of peritoneal metastases of ovarian cancer (PMOC). Given the increasing rate of neoadjuvant chemotherapy in patients with high PCI, prior abdominal surgeries, inflammation and fibrotic changes, the benefit of removing any "peritoneal scar-like tissues" (PST) during CRS, hasn't been thoroughly investigated. Our objective in this retrospective cohort was to identify the proportion of malignant cells positivity in PST of patients with PMOC, undergoing curative-intent CRS ± HIPEC.info:eu-repo/semantics/publishe
