Shear Wave Ultrasonographic Elastography in Pediatric Spleens and Its Role in Differential Diagnosis.

Shear wave elastography (SWE) has become popular in clinical practice for many diseases. However, there is not adequate research on spleen-related diseases. This study aimed to investigate the potential of quantitative values obtained through SWE in evaluating spleen pathologies in the pediatric population and to demonstrate its performance to differentiate splenomegaly-related diseases. The research group retrospectively included children with pathological diagnoses related to the spleen from November 2016 to April 2021, and they were categorized into three groups, including portal hypertension (PH), benign lymphoid hyperplasia (BLH), and malignant infiltration (MI). Spleen sizes and parenchymal stiffness were also calculated for each group. Subsequently, mean spleen stiffness in each group was compared with normal values within the same age group. In total, 2781 children (1379 children for the study group; 1402 children for the control group) were enrolled in the study. The highest stiffness was observed in the PH group, which is statistically higher than others (p < 0.05). Although the mean spleen stiffness in the group with BLH was higher than the control and MI group, the difference was not statistically significant (p = 0.08). The mean stiffness in the group with MI was significantly lower than both the control group (p = 0.005) and PH (p = 0.01). In conclusion, using SWE in the differential diagnosis of etiologies causing splenomegaly could make an important contribution.

Normal umbilical artery doppler values in 18-22 week old fetuses with single umbilical artery.

Umbilical cord with a single umbilical artery (SUA) can carry twice the blood volume of a three-vessel cord (TVC). So, the normal hemodynamics of the fetuses with SUA was different from those with TVC. Furthermore, structural abnormalities, fetal aneuploidy, and intrinsic growth retardation may be associated with the presence of a SUA. In order to evaluate these patients, intermittent doppler measurements have been suggested. From this point, we aimed to determine the CDUS flow parameters in SUA cases and to demonstrate that these flow parameters are different from the TVC parameters. Ultrasound (US) examinations were performed in the 18-22 weeks of gestation during routine fetal anatomy screening. Resistance index (RI), Pulsatility index (PI), and S/D: systole to diastole ratio values were measured. The samples were taken from the proximal, mid-portion, and distal of the umbilical cord. In addition to Doppler Ultrasound values, AC and estimated fetal weight (EFW) values were also recorded. The study included 167 pregnant women, 86 of whom were study group with SUA and 81 were control group with TVC. The measurements of RI, PI, and S/D at all three levels were significantly lower in the SUA group compared to the TVC group. The resistance in the UA of fetuses with SUA is lower than in fetuses with TVC. The resistance in the UA of fetuses with SUA decreases from the fetal end to the placental end. Knowing the normal values for fetuses with SUA might provide a better and more reliable Doppler Ultrasoundassessment.

Commentary on "Gallstone associated celiac trunk thromboembolisms complicated with splenic infarction: A case report''.

The present letter to the editor is related to the study titled "Gallstone associated celiac trunk thromboembolisms complicated with splenic infarction: A case report''. Although gallstones are relatively common diseases, its association with thromboembolism is not fully understood. We aim to emphasize the potential mechanism of this relationship in this letter. In addition, we wanted to contribute to the causes of the spleen infarction and celiac trunk pathologies.

Commentary on "Primary orbital monophasic synovial sarcoma with calcification: A case report".

The present letter to the editor is related to the study titled "Primary orbital monophasic synovial sarcoma with calcification: A case report''. Orbital synovial sarcoma is one of the rare intraorbital masses seen in adult and pediatric populations. Some case reports in the literature revealed that synovial sarcoma may contain calcifications. Therefore, it is important to make differential diagnosis among calcified orbital masses in childhood.

Sonographic findings of COVID-19 related acute scrotal infection and associations with clinical-laboratory data.

BACKGROUND: During the Coronavirus Disease 2019 (COVID-19) pandemic, patients present to hospitals with a wide range of symptoms. Some of these symptoms include acute orchitis and epididymitis. The goal of this research is to see if COVID-19 infection and scrotal infection are associated. MATERIALS AND METHODS: Patients with a COVID-19 (+) who agreed to a scrotal ultrasound (US) examination were studied prospectively in a tertiary care center between October 2021 and February 2022. The severity of the disease was used to divide patients into groups. Patients diagnosed with acute scrotal infection based on scrotal ultrasonography findings were compared in these groups, as were their age, comorbidities, and laboratory data. RESULTS: The median age of the 213 participants was 61.7 ± 8.3. During the ultrasonographic examination of the patients, 15 (7%), 8 (3.7%), 17 (7.9%), and 40 (18.7%) were diagnosed with acute orchitis, acute epididymitis, acute epididymo-orchitis, and scrotal infection, respectively. Acute scrotal infection was far more common in patients with a higher clinical severity of the disease. The patients' comorbidities were also assessed, and it was discovered that they were statistically more common in the same group. CONCLUSIONS: Even if there are no clinical symptoms, ultrasonography can help detect acute scrotal infection in COVID-19 patients. Furthermore, in groups with higher clinical severity, this association is more likely to be seen. It is critical to understand this in order to avoid complications.

Pediatric skull fractures: could suture contact be a sign of abuse?

PURPOSE: Skull fractures in infants and young children can occur as a result of both accidental trauma and abuse. 1/3 of children with abuse-related head trauma and 1/5 of children with abuse-related fractures were overlooked during the initial evaluation. In this study, we aim to investigate the prevalence of skull fractures that come into contact with the suture in head traumas caused by accidents and abuse, and also to see if contact of the fracture line with the suture could be used as a sign for abuse in the pediatric population. METHODS: Forry-four patients with head trauma were retrospectively assessed between January 2010 and June 2020 and were confirmed to have fractures on a brain CT. Patient age, gender, and head injury type were recorded. The fracture site, location and number, the contact of the fracture line with the suture, the name, and number of the suture it came into contact with were determined. RESULTS: Twenty-eight skull fractures in 22 children with a diagnosis of child abuse and 25 skull fractures in 22 children due to accidental trauma were evaluated in the same age and gender range. Eighteen (64%) of 28 abuse-related skull fractures were in contact with two or more sutures. Two (8%) of 25 accident-related fractures were related to two or more sutures. Abuse-related fractures had a significantly higher suture contact rate than accident-related fractures (p = 0.007). CONCLUSION: Contact with two or more sutures of a skull fracture is a finding related to abuse rather than accident.

Evaluation of thorax computed tomographic findings in COVID-19 variant cases.

BACKGROUND: Because of genetic mutations occurring during viral replication, new SARS-CoV-2 variants will continue to emerge. Throughout the COVID-19 pandemic, thorax computed tomographic (CT) findings have played a crucial role in the diagnosis and follow-up of patients with COVID-19. In this study, we compared the thorax CT findings of patients infected with SARS-CoV-2 variants (variant group) with those of patients infected with the non-variant strain (non-variant group) to assess if thorax CT findings may be utilized to discriminate between the groups. Furthermore, we compared demographic and laboratory data between the groups. METHODS: The study comprised a total of 77 patients who presented to our hospital with a preliminary diagnosis of COVID-19 based on clinical symptoms, a positive oropharyngeal/nasopharyngeal swab RT-PCR testing, and thorax CT examinations. Patients' laboratory and demographic features as well as thorax CT findings were retrospectively evaluated, and the results were grouped according to RT-PCR results. RESULTS: There were 42 patients in the non-variant group and 35 patients in the variant group. The average age of patients infected with the non-variant strain, alpha variant, and gamma variant was 63.52 ± 14.87 years, 54.86 ± 14.31 years, and 59.4 ± 17.79 years, respectively. The average age of the variant group was significantly lower than that of the non-variant group. There was no significant difference in thorax CT findings between the groups, and consolidation, ground glass densities, and cobblestone pattern in the bilateral lower lobes and peripheral areas were the most common thorax CT findings in both the groups. CONCLUSION: There is no significant difference in thorax CT findings between the variant and non-variant groups. Therefore, clinical and laboratory characteristics should take precedence over thorax CT findings for distinguishing between patients infected with SARS-CoV-2 variants and the non-variant strain.
