Objective: It is believed that postural balance problems may contribute to the development of adolescent idiopathic scoliosis (AIS). Vision provides proprioceptive input by supplying information about body positions. Considering the fundamental role of vision in postural control, this study aims to investigate the relationship between AIS and the volume of the eye-moving muscles and the visual field. Materials and Methods: This prospective cross-sectional study included a total of 47 female individuals, with 24 having AIS and 23 being healthy participants. Magnetic resonance imaging was used to calculate the volumes of the medial rectus (MR) and lateral rectus (LR) muscles in both groups. Additionally, the visual field test was conducted to determine the pattern standard deviation (PSD) and mean deviation (MD) values for the left and right eyes of individuals in both groups. Results: The mean age of AIS patients with a major curvature of 48.50 degrees and a Lenke Type-1 curve was similar to that of asymptomatic individuals. The volume values of the MR muscle on both sides were lower in the AIS group compared to the control group (p<0.05). Significant differences were found in the PSD values of the visual field test within the AIS group (p<0.01). However, there was no significant difference in the MD values between the left and right eyes of the two groups (p>0.05). Conclusion: It is important to consider the presence of visual sensory defects in individuals with AIS. It is unknown whether AIS causes visual impairment or vice versa. Therefore, further comprehensive studies are needed. [ABSTRACT FROM AUTHOR]

Objective: Shear wave elastography can detect inflammation and fibrosis in the thyroid tissue. It can be used to evaluate Hashimoto's thyroiditis or in the assessment of thyroid diseases accompanying type 1 diabetes mellitus. Our aim was to examine whether there is a difference between the shear wave elastography scores as kilopascals of individuals with type 1 diabetes mellitus and healthy children, and the relationship between diabetes-related parameters and shear wave elastography scores. Materials and Methods: A total of 77 type 1 diabetes mellitus children and 53 healthy controls were compared. Serum thyroid-stimulating hormone, free thyroxine, free tri-iodothyronine, antibodies against thyroid peroxidase and thyroglobulin, average of the last 2 control plasma glycosylated hemoglobin A1c, duration of diabetes and daily insulin dose in diabetic individuals, thyroiditis staging by ultrasound, and shear wave elastography scores were also recorded. Results: In terms of shear wave elastography scores, no significant difference was found between the healthy control group and the group with type 1 diabetes mellitus without Hashimoto's thyroiditis (7.9 ± 2.8 kPa vs. 8.4 ± 3.3 kPa, P = .772). The score of the group with type 1 diabetes mellitus accompanied by Hashimoto's thyroiditis (15.1 ± 6.6 kPa) was found to be higher than the group with type 1 diabetes mellitus without Hashimoto's thyroiditis and the healthy control group (P = .022 and P = .015, respectively). Conclusions: This is the first study to compare children with type 1 diabetes mellitus and healthy controls in terms of shear wave elastography scores. We found that there was no significant difference between the shear wave elastography scores of children with type 1 diabetes mellitus without Hashimoto's thyroiditis compared to healthy controls.

Objective: Some factors (age, weight, height, body mass index, body surface area, puberty stage, and iodine nutrition status) may affect thyroid volume (TV). We aimed to investigate the differences between chronological age and height age in interpreting goiter. Materials and Methods: The thyroid ultrasonography records of 420 children aged 1--18 years were evaluated. We searched the difference between the interpretations of goiter by recalculating the TV standard deviation score (SDS) in terms of both chronological ages and corrected for height age. We also evaluated those with negative thyroid autoantibodies and normal thyroid hormone levels by subgroup analysis. The evaluation of TV according to chronological age and height age and the change of goiter interpretation were compared with the McNemar test. Results: A total of 180 children who had euthyroid and negative thyroid autoantibodies were analyzed. A weak correlation was detected between TV and age (r=0.29, p<0.001), body weight (r=0.35, p<0.001), height (r=0.32, p<0.001), height age (r=0.32, p<0.001), body weight SDS (r=0.20, p=0.008) and height SDS (r=0.21, p=0.005). When the changes of goiter interpretation were compared, a statistically significant difference was determined in the whole group (p=0.029); however, there was no significant difference in children who were both euthyroid and found to have negative thyroid auto-antibodies (p=0.375). Conclusion: We observed that the interpretation of goiter changed according to chronological age and height age if thyroid hormone level and/or thyroid autoantibody positivity were included.

Objective: The prevalence of acute pancreatitis and acute recurrent pancreatitis in children has increased over the years, and there are limited data about imaging findings. This study aimed to reveal the imaging findings of acute pancreatitis and acute recurrent pancreatitis in children at a tertiary care hospital. Materials and Methods: The patients with acute pancreatitis and acute recurrent pancreatitis diagnosed between January 2007 and December 2018 were included. Demographic and clinical features, follow-up period, and interventions were noted. Imaging features were evaluated for pancreatic enlargement, peripancreatic fluid, and biliary ducts for initial examination and pancreas parenchymal necrosis, peripancreatic collection, walled-off necrosis, pseudocyst, parenchymal atrophy, and biliary ductal dilatation for follow-up. Results: The study included 74 patients with a mean age of 9 ± 4.9 years. The most common causes of acute pancreatitis and acute recurrent pancreatitis were biliary tract anomalies (n = 21), biliary ductal stones (n = 9), and cystic fibrosis (n = 8). Findings consistent with acute pancreatitis were determined by ultrasound in 40.5% (n = 30/74), whereas by magnetic resonance imaging in 60% (n = 39/65). Forty-one percent of the patients (n = 16) with positive magnetic resonance imaging findings did not show any findings on ultrasound. Acute recurrent pancreatitis was seen in 32 patients (43.2%). Follow-up imaging was performed in 55 patients (74.3%) between 2 months and 11 years. At follow-up, 8 patients had peripancreatic collections (6 walled-off necrosis and 2 pseudocysts). Conclusion: Recognizing the imaging findings of acute pancreatitis and its complications is crucial. Magnetic resonance imaging should be preferred as a second option following ultrasound, with the advantages of biliary ductal system delineation and better characterization of complications.

Purpose: We aimed to assess the MRI findings and follow-up of multiple focal nodular hyperplasia (FNH)- like lesions in pediatric cancer patients diagnosed by imaging findings.Methods: We retrospectively analyzed clinical data and MRI examinations of 16 pediatric patients, who had been scanned using gadoxetate disodium (n=13) and gadobenate dimeglumine (n=3). Hepatic nodules were reviewed according to their number, size, contour, T1- and T2-weighted signal intensities, arterial, portal, delayed and hepatobiliary phase enhancement patterns. Follow-up images were evaluated for nodule size, number, and appearance.Results: All 16 patients received chemotherapy in due course. Time interval between the initial diagnosis of cancer and detection of the hepatic nodule was 2-14 years. Three patients had a single lesion, 13 patients had multiple nodules. The median size of the largest nodules was 19.5 mm (range, 8-41 mm). Among 16 patients that received hepatocyte-specific agents, FNH-like nodules appeared hyperintense in 11 and isointense in 5 on the hepatobiliary phase. During follow-up, increased number and size of the nodules were seen in 4 patients. The nodules showed growth between 6-15 mm.Conclusion: Liver MRI using hepatocyte-specific agents is a significant imaging method for the diagnosis of FNH-like lesions, which can occur in a variety of diseases. Lesions can increase in size and number in pediatric patients. [ABSTRACT FROM AUTHOR]
