Management of Chyle Leak in Pediatric Surgical Oncology: A Systematic Review.

INTRODUCTION: Chyle leak, a rare complication, arises from damage to primary lymphatic vessels due to congenital factors or medical interventions, leading to conditions such as chylothorax and chylous ascites. Managing chyle leaks is challenging, especially in pediatric surgical oncology, often arising as postoperative complications. Treatment options range from conservative dietary adjustments to surgical interventions, depending on leak severity and patient condition. This systematic review examines the management of chyle leaks in pediatric surgical oncology, emphasizing both conservative and surgical approaches. METHODS: This systematic review involved extensive database searches (EMBASE, Web of Science, and PubMed) to identify relevant studies on chyle leak management in the pediatric population. The review included studies from 1982 to 2023 and focused on pediatric and adolescent patients, assessing various treatment approaches and outcomes. Nine articles composed of 163 patients (study population size ranging from 2 to 82 patients). Independent reviewers evaluated the selected studies for inclusion. RESULTS: Among 9 articles analyzed, 98.8% of pediatric patients initially received conservative management for chyle leaks, with 11.7% eventually requiring surgical intervention due to persistent leaks (8, 10, and 16 to 22). Neuroblastoma resection is associated with 20% to 40% rate of chyle leak, and the extent of lymphadenectomy has been identified as a risk factor for chyle leak. The study highlighted variability in clinical success rates based on conservative management approaches. DISCUSSION: Chyle leak, while rare, presents a complex challenge, especially in pediatric surgical oncology. Various causes and treatment options exist, with a preference for conservative management initially and surgical intervention in specific circumstances. Factors such as leak severity and patient condition guide the choice between approaches. However, the scarcity of comparative data and randomized trials in the pediatric population necessitates further research to establish optimal management strategies for chyle leaks. CONCLUSIONS: Conservative management of chyle leaks has proven to be the preferred approach in early stages of treatment, whereas surgical management could be the preferred choice in certain situations. Larger prospective studies are needed to further evaluate these results.

Translation and Validation of the Sinus and Nasal Quality of Life Surgery Survey in Serbian.

Objective: The aim of this study was to translate the Sinus and Nasal Quality of Life Surgery Survey into the Serbian language to evaluate the test-retest reliability and validity. Study Design: The study included 49 consecutive patients between 12 and 18 years old with rhinologic symptoms. Patients were given a paper survey to complete along with a link to complete the online survey within the same day. Setting: The study was conducted at the University Children's Hospital Clinic for Pulmonology and Allergology between January 2023 and March 2023. Methods: Responses between the paper and online survey were compared and regression analysis was performed to evaluate the relationship. Internal reliability and test-retest reliability were assessed using Cronbach's α coefficient and intraclass correlation coefficient. All data were collected and analyzed using SPSS 29.0. Results: Pearson correlation coefficient between the paper and online survey was very high and statistically significant (r = 0.999; P < .001). Each item had a high correlation (0.993-1.000), where the lowest correlation coefficient was obtained from question 2 (0.993). Average scores in each item differed slightly for only item 2 (mean difference = -0.041), but not to the level of statistical significance. Bland-Altman plot indicated no proportional bias between the 2 versions. Linear regression analysis suggested a high level of agreement between the 2 versions (slope = 1.00, R 2 = 0.999). Conclusion: The survey is a useful questionnaire to evaluate the quality of life in patients with rhinologic symptoms. The high correlation between the paper and online survey shows the reliability of the questionnaire regardless of administration modality.

Elevated Transaminases as Predictors of COVID-19 Pneumonia Severity.

BACKGROUND: This study aimed to calculate the frequency of elevated liver enzymes in hospitalized patients with coronavirus disease 2019 (COVID-19) infection and to test if liver enzyme biochemistry levels on admission could predict the computed tomography (CT) scan severity score of bilateral interstitial pneumonia. METHODS: This single-center study comprised of 323 patients including their demographic data, laboratory analyses, and radiological findings. All the information was taken from electronic health records, followed by statistical analysis. RESULTS: Out of 323 patients, 115 of them (35.60%) had aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) over 40 U/L on admission. AST was the best predictor of CT scan severity score of bilateral interstitial pneumonia (R2 = 0.313, Adjusted R2 = 0.299). CT scan severity score in the peak of the infection could be predicted with the value of AST, neutrophils, platelets, and monocytes count (R2 = 0.535, Adjusted R2 = 0.495). CONCLUSION: AST, neutrophils, platelets, and monocytes count on admission can account for almost half (49.5%) of the variability in CT scan severity score at peak of the disease, predicting the extensiveness of interstitial pneumonia related to COVID-19 infection. Liver enzymes should be closely monitored in order to stratify COVID-19 patients with a higher risk of developing severe forms of the disease and to plan the beforehand step-up treatment.
