Myopericytoma is a rare vessel wall tumor, a subtype of hemangiopericytoma that usually develops subcutaneously. Intravascular myopericytoma is a rarer subtype, with only few cases reported in the literature and even fewer with imaging modalities included. We report the case of a 36-year-old man who was referred to our institution with a painless, palpable mass in the right arm and was evaluated with MRI, grey-scale and Doppler-mode ultrasound. Tumor histopathology and imaging characteristics are presented together with the role that each imaging modality played in the management of the patient.

The translocation involves a fusion between one of the SSX genes (SSX1, SSX2, or SSX4) and the SS18 gene (SYT), with the fusion protein participating in the formation of the SWI/SNF and Polycomb complexes, playing a role in epigenetic gene regulation. In the described patient, the negative FISH test for this translocation did not allow for a clear differential diagnosis. [...]BCL-2 analysis was subsequently performed. The use of gene expression studies (RNAseq) is becoming useful for understanding the epigenetic mechanisms underlying synovial sarcoma and its prognosis and aggressiveness [4]. [...]we reiterate the significance of imaging in achieving an accurate diagnosis, particularly concerning the precise localization of pericardial tumors, including those of uncommon occurrence.

We report a case of a 52-year-old woman who was referred to our institution with a superior vena cava syndrome and was investigated through echocardiography, CT and MRI revealing a well-defined, encapsulated pericardial mass. The pathology, correlated with the immunohistochemical analysis, concluded it was an extremely rare primary pericardial synovial sarcoma. The patient underwent surgery and chemotherapy with a 16-month disease-free survival and passed away after a contralateral aggressive relapse. Moreover, we discuss the role of each imaging modality together with their pericardial synovial sarcoma reported features.

Echocardiography is the first technique used for diagnosing cardiovascular malformations (CVM). The results are often completed with multi-detector computer tomography (MDCT) and/or magnetic resonance imaging (MRI) for confirming/ invalidating an abnormal pulmonary venous return in the case of atrial septal defect (ASD) or for the exact interpretation of cardiac function in pre/post-surgery cases with ASD, ventricular septal defect (VSD), and Fallot tetralogy. MDCT and MRI play an important role in the precise and complete diagnosis of Fallot tetralogy, in the anomalies of the right heart cavities and the arterial and venous pulmonary tree, the anomalies of the emergence and course of the coronary arteries, aortic coarctation and developmental anomalies of the aortic arch and supraaortic trunks. The complementarity of echocardiography with MDCT and MRI, in order to obtain details and to avoid invasive procedures and also the cooperation between the pediatrician, cardiologist, surgeon and radiologist, represent the key to the diagnosis and treatment of cardiovascular malformations, for the benefit of the patient.

The diagnosis of cardiovascular malformations (CVM) is based on the echocardiographic evaluation. Multidetector computed tomography (MDCT) and magnetic resonance imaging (MRI) are performant, necessary techniques for the pre- and postoperative assessment of complex malformations, especially of cyanogenic malformations, in which anomalies of the right side of the heart and of the pulmonary circulation are involved and where echocardiography has a limited role. The complementarity of echocardiography with MDCT and MRI for the acquisition of the details necessary for an accurate therapeutic decision and for avoiding invasive exploration, as well as the close relationship between the radiologist and the clinician are crucial and all the more necessary in complex malformations.

Pediatric obesity is a growing public health concern, significantly increasing the risk of metabolic and cardiovascular comorbidities. Background/Objectives: This study aims to explore the burden of obesity, its associated comorbidities, and resting metabolic rate (RMR) assessed by indirect calorimetry among children and adolescents in a cohort of 223 participants from Nord-East of Romania. Methods: A cross-sectional study was conducted among 223 children and adolescents (aged 4–18 years) who were diagnosed with obesity at Saint Mary Emergency Children’s Hospital Iași. Anthropometric measurements, clinical assessment, and biochemical parameters were recorded. RMR was measured by indirect calorimetry, using the Fitmate Pro Metabolic Technology (Cosmed, Rome, Italy), under a stable environment for 15 min, following a fasting period of minimum 6–8 h. Data were analyzed using SPSS 22.0, applying descriptive statistics and Pearson correlations. Results: A total of 223 participants were included in the analysis, with a mean age of 12.03 ± 3.32 years (range 4–17 years) and a mean body mass index (BMI) of 31.21 ± 5.84 kg/m2. The average RMR was 1687.5 ± 425.5 kcal/day, with higher values in males compared with females. RMR showed significant positive correlations with age (r = 0.60), BMI (r = 0.51), waist circumference (r = 0.67), and fat mass measured with a three-site formula technique (r = 0.51) and systolic (r = 0.45) and diastolic blood pressure (r = 0.19), all with p < 0.001. A weak inverse correlation was observed between RMR and the fitness index (r = −0.24, p < 0.001), indicating an association between lower fitness scores and higher RMR values. RMR showed no significant correlation with fasting glucose or lipid levels, indicating that metabolic rate was more influenced by body composition than by biochemical markers. Conclusions: Pediatric obesity is strongly linked to multiple comorbidities, emphasizing the need for early detection and targeted interventions. Higher BMI and central adiposity were associated with increased RMR. Indirect calorimetry provides valuable insights into the metabolic profile of children with obesity and can inform individualized management strategies.

Introduction: Childhood and adolescent obesity is a growing global health challenge associated with early metabolic and cardiovascular complications. This study aims to compare questionnaire-assessed physical activity patterns and lifestyle characteristics among children and adolescents with obesity and normal-weight peers and to explore their associations with clinical measurements and cardiometabolic risk. Assessing resting metabolic rate (RMR) by indirect calorimetry may provide additional insight into metabolic status beyond conventional anthropometric indicators. Methods: This prospective cross-sectional study included 58 children and adolescents aged 5–18 years with obesity and 30 normal-weight controls evaluated in Sfânta Maria Emergency Children’s Hospital Iași, Romania. Clinical data included anthropometric measurements and available biochemical parameters. RMR was assessed through indirect calorimetry (Fitmate Pro, Cosmed, Rome, Italy). Parents completed a structured lifestyle questionnaire adapted from validated international instruments, collecting information on physical activity, sedentary behavior, and wearable device use. Data analysis was conducted using SPSS 22.0, applying descriptive statistics and Pearson correlation analysis. Results: Children with obesity reported higher body mass index (BMI) (30.48 ± 5.31 kg/m2), higher RMR values, lower physical activity levels and greater sedentary time than controls. RMR correlated positively with BMI, central adiposity, blood pressure, waist-to-height, hepatic steatosis and exercise tolerance. Although electronic devices for monitoring physical activity were more frequently used in the obesity group, this was not associated with higher activity levels. Conclusions: Children and adolescents with obesity exhibited a clustered cardiometabolic risk profile and reduced physical activity. RMR measured by indirect calorimetry may contribute to a more comprehensive metabolic assessment in pediatric obesity.

Aims. In the present study, we aimed to assess the concentrations of IL-13 and IL-17 in serum of patients with early rheumatoid arthritis (eRA), the investigation of correlation between the concentrations of these cytokines and disease activity score, and the concentration of some autoantibodies and the evaluation of the utility of IL-13 and -17 concentration measurements as markers of disease activity. Materials and Methods. Serum samples were collected from 30 patients and from 28 controls and analysed parameters. Results. The serum concentrations of IL-13, IL-17, anti-CCP, and IgM-RF were statistically significantly higher in patients with eRA, compared to the controls. IL-13 concentrations in the severe and moderate groups with eRA were statistically higher than in the mild and control groups. Also, in the case of IL-17, serum concentrations increased proportionally with the disease activity of eRA. We observe that concentrations of IL-13 and -17 did not correlate with autoantibodies. IL-17 concentration significantly positively correlated with CRP, while IL-13 concentration significantly negatively correlated with CRP. Disease activity score, DAS28, was strongly positively correlated with levels of ESR and weakly positively correlated with concentrations of anti-RA33 autoantibodies. IL-13 has a higher diagnostic utility than IL-17, CRP, ESR, IgM-RF, and anti-CCP as markers of disease activity. Conclusions. The presence of higher IL-13 and IL-17 serum levels in patients, compared with those of controls, confirms that these markers, found with high specificity, might be involved in the pathogenesis of eRA. IL-13 and IL-17 might be of better usefulness in the prediction of eRA activity status than IgM-RF and anti-CCP.

Background: Vitamin D plays an important role in maintaining bone health with numerous benefits for extraskeletal health as well. Objectives: We aimed to assess the prevalence of vitamin D deficiency in children (0–18 years old) in a tertiary hospital in Romania between August 2019 and January 2024 and to investigate the role of adequate supplementation in this vulnerable population. Methods: The serum 25(OH)D levels were measured using a chemiluminescence binding assay. Results: A total of 744 participants were included in this study: 396 female (53.23%) and 348 male (46.77%). The serum levels of 25(OH)D ranged between 2.2 and 125.4 ng/mL, with a mean value of 27.4 ng/mL and a median value of 23.5 ng/mL. According to the cutoff values for the definition of vitamin D status (severe deficiency: <10 ng/mL, deficiency: <20 ng/mL, insufficiency: 20–29 ng/mL, and sufficiency: ≥30 ng/mL), the sample consisted of 77 (10.34%) cases of severe deficiency, 221 (29.7%) cases of deficiency, 194 (26.07%) cases of insufficiency, and 245 (32.93%) cases of sufficiency. There were seven cases of hypervitaminosis D with values above 100 ng/mL. The mean values (and corresponding 95% confidence intervals, CIs) were as follows: 27.85 ng/mL [25.95–29.76] in the males, 22.45 ng/mL [25.12–28.82] in the females, 24.82 ng/mL [21.86–27.77] in the spring, 28.62 ng/mL [26.42–30.81] in the summer, 32.30 ng/mL [29.16–35.44] in the autumn, and 24.01 ng/mL [21.57–26.44] in the winter. We observed a notable decline in the serum 25(OH)D levels with age, with 82.08% of the children in the age group above 6 years old having serum 25(OH)D levels below 30 ng/mL. In obese subjects, a higher prevalence of hypovitaminosis D was observed compared to non-obese subjects, with a mean value of 19.54 [17.50–21.57] ng/mL in obese children versus 28.89 [27.39–30.40] ng/mL in normal weight children. Conclusions: In our sample, the mean serum concentration of 25(OH)D was 27.4 ng/mL. Notably, 66.11% of the cases demonstrated varying degrees of hypovitaminosis D, with a significantly higher prevalence of 86.16% observed in the obese group. Healthcare providers should prioritize routine screening for vitamin D levels in pediatric patients with obesity to facilitate timely intervention and personalized supplementation strategies tailored to individual needs
