    Introduction: Inflammation is one of the factors involved in the occurrence and progression of acute kidney injury (AKI). We evaluated the relationship between preoperative systemic inflammatory markers and early postoperative AKI development in pediatric liver transplantation (LT) patients. Methods: Data from 190 pediatric patients were retrospectively analyzed. The preoperative neutrophil-to-lymphocyte ratio (NLR), systemic immune-inflammation index (SII), and pan-immune-inflammation value (PIV) levels were calculated. AKI was classified according to the Kidney Disease: Improving Global Outcomes staging. Patients who did not develop AKI in the early postoperative period were classified as group 0, patients with stage 1 AKI were classified as group 1, and patients with stage 2-3 AKI were classified as group 2. The relationship between the inflammatory parameters and AKI was evaluated. Results: AKI developed in 20% of patients, and 16.31% of these patients had severe AKI. The NLR, SII, and PIV values were significantly higher in patients with severe AKI (p<0.001). Preoperative high PIV values were found to be an independent predictor of AKI development. Conclusion: High preoperative PIV values may be used as a predictive factor for the development of early AKI in patients undergoing pediatric LT.

    Comparison of Urinary Tract Dilatation and Society of Fetal Urology systems in the detection of vesicourethral reflux and renal scar

    Purpose: The presence and degree of hydronephrosis is very important in the management of many diseases of the urinary tract. In this study, we aim to compare the sensitivity and specificity of 2 classification systems that are used for hydronephrosis grading in ultrasound, for reflux and scar detection. The classification systems were the Society of Fetal Urology (SFU) and Urinary Tract Dilatation (UTD). Material and methods: Ultrasounds and dimercaptosuccinic acid scintigraphies (DMSA) of all patients who underwent voiding cystourethrogram (VCUG) due to urinary tract infection were examined retrospectively. DMSA was accepted for scar detection and VCUG for reflux detection as reference methods. SFU classification was used for hydronephrosis in ultrasound reports, and UTD classification was made over the reports. Sensitivity, specificity, and positive and negative predictive values of UTD and SFU classification systems for reflux and scar detection were calculated, and these 2 systems were compared. Results: 103 (39%) of the patients were male and 162 (61%) were female. Pathologies were detected in 192 (35%) of 530 kidneys in ultrasound. In 110 (42%) of the children, reflux was detected in VCUG. Scars in DMSA were detected in only 16% (44) of 266 kidneys. Sensitivity, positive and negative predictive values of the UTD classification system were statistically significantly higher than the SFU system for scar and reflux detection (p < 0.01). Conclusions: If we use the UTD system in ultrasounds of patients with urinary tract infections, children reported as UTD 0 may not need VCUG, which reduces radiation exposure to children and the cost of the diagnostic interventions.

    Evaluation of Salivary Glands by Ultrasonography and Inflammatory Markers in Children with Autoimmune Thyroiditis
    (Galenos Publ House, 2023) Tasolar, Sevgi Demiroz; Sigirci, Ahmet; Ciftci, Nurdan; Cengiz, Aslinur; Dogan, Gulec Mert; Akinci, Aysehan
    Introduction: Although more common in adults, autoimmune thyroiditis (AT) is one of the most common thyroid diseases in children and adolescents. Salivary gland involvement has been described in many studies of patients with AT. Several inflammatory scores are used to assess the inflammatory status of patients with systemic autoimmune diseases. We aimed to sonographically evaluate the parotid and submandibular salivary glands with inflammatory parameters in patients with AT in our study. Methods: Our study population consisted of 37 consecutive pediatric AT patients and 29 healthy control subjects. Ultrasonographic and laboratory evaluations of the study population were performed. Jamovi and MedCalc software were used to analyze the data. Results: The volume of the thyroid gland in the patients was significantly higher than that in the control group (p=0.030), while there was no difference in the volume of the salivary glands. Multiple logistic regression analysis was planned to assess the predictability of salivary gland involvement in patients with the disease. Both systemic immune-inflammation index (SII) and pan-immune inflammation value (PIV) were found to be predictors of salivary gland involvement in AT patients. Conclusion: We found that both SII and PIV inflammatory markers are predictive of salivary gland parenchymal changes in patients with AT, and SII is likely to be more valuable than PIV at this time.
