Abstract
PURPOSE Awareness of normative values of extra orbital structures would provide useful information to interpret the radiological images better and use them for diagnostic purposes. This study aimed to reveal the average values of major extraocular structures measured on magnetic resonance images. METHODS In this retrospective cross-sectional study, magnetic resonance (MR) images of 256 orbits of 128 patients were re-interpreted regarding the measurements of major orbital structures. Extraocular muscles, superior ophthalmic vein, and optic nerve-sheath complex were measured on orbital MR images of these patients. The data distributions were presented by box-plot analyses for each parameter, and the measurement results were analyzed regarding gender and age groups. RESULTS Lateral rectus muscle thickness (LR), inferior rectus muscle thickness (IR), globe position (GP), and interzygomatic line (IZL) values were higher in the male group than in the female group (p values were < 0.001, 0.003, 0.020, and < 0.001 respectively). LR, the thickness of the superior group muscles (SUP GR), IR, superior oblique muscle thickness (SOBL), and the thickness of optic nerve-sheath complex (ON) values indicated a significant relationship between age groups. There was a significant, positive, and low-level correlation between age and LR, SUP GR, and IR values (p values were < 0.001, 0.001, and < 0.001, respectively). CONCLUSION This study provides quantitative data on normative values of orbital structures with gender and age group comparisons. Clinicians or surgeons can easily use the measured values to gather diagnostic information from the orbital region.

Abstract
Purpose In this study, the effect of the most superior point of patella-entrance of femoral trochlea distance ratio (SP-ET index) on chondromalacia patella (CP) was investigated with 2 reviewers. Material and methods A total of 348 knees of 308 patients were analysed retrospectively with magnetic resonance imaging (MRI). Patients with or without CP constituted the study and the control groups in this cross-sectional investigation. Two reviewers interpreted the dataset regarding the SP-ET index. This ratio was calculated as the distance between the most superior point of patella and the entrance of femoral trochlea (β) divided by the patellar articular surface length (α). The relationship between the SP-ET index and CP was presented using independent samples T-tests, and the intraclass correlation coefficient (ICC) was calculated to reveal the interobserver differences. Results There was excellent agreement between the reviewers regarding α, β, and SP-ET values (ICC was 0.971, 0.964, and 0.943, respectively). Higher SP-ET values were obtained for patients with CP, in comparison with patients without any chondral lesion (p < 0.001). A significant, positive, and moderate level of correlation was revealed between SP-ET measurements and CP grades for the total study population. Conclusions SP-ET index showed high interobserver agreement and indicated a significant difference between patients with and without CP. Both reviewers' results indicated positive and significant correlation between the measured SP-ET values and different grades of CP for females, males, and the total study population.

Abstract
PURPOSE When a suspected hepatic alveolar echinococcosis (AE) lesion is detected on a contrast enhanced computed tomography (CT) scan, an additional triphasic or non-enhanced CT scan is required to determine the presence of calcification and enhancement. As a result, imaging costs and exposure to ionizing radiation will increase. We can create a non-enhanced series from routine contrast-enhanced images using dual-energy CT (DECT) and virtual non-enhanced (VNE) images. This study's objective is to assess virtual non-enhanced DECT reconstruction as a potential diagnostic tool for hepatic AE. METHODS Triphasic CT scans and a routine dual energy venous phase were acquired using a third-generation DECT system. A commercially available software package was used to generate VNE images. Individual evaluations were conducted by two radiologists. RESULTS The study population consisted of 100 patients (30 AE, 70 other solid liver masses). All AE cases were diagnosed [no false positives/negatives, 95% confidence interval (CI) sensitivity: 91.3%-100%; 95% CI specificity: 95.3%-100%]. Interrater agreement was k: 0.79. In total, 33 (33.00%) of the patients had AE, which was detected using both true non-enhanced (TNE) and VNE images. The mean dose-length product of a standard triphasic CT was significantly higher than biphasic dual-energy VNE images. CONCLUSION In terms of diagnostic confidence, VNE images are comparable with actual non-enhanced imaging when evaluating hepatic AE. Further, VNE images could replace TNE images with a substantial radiation dose reduction. Advances in knowledge: hepatic cystic echinococcosis and AE are serious and severe diseases with high fatality rates and a poor prognosis if managed incorrectly, especially AE. Moreover, VNE images produce equal diagnostic confidence to TNE images for assessing liver AE, with a significant reduction in radiation dose.

Abstract
PURPOSE The main purpose of this study was to evaluate the intervertebral disc height and intervertebral disc degeneration between the normal group and the group with disc herniation at the level of the L4-L5 intervertebral disc by MRI using the Pfirrmann grading system. MATERIALS AND METHODS 385 patients were included in this study. MRI images were reevaluated and intervertebral disc heights were measured from the anterior, middle and posterior segments. Researchers divided disc pathologies into two groups. In the non-herniated group; normal or bulging ones; in the herniated group, they included those with protrusion or extrusion. RESULTS 385 lumbar MRI examinations meeting the study criteria were included in study. There were 56.9% (219/385) females and 43.1% (166/385) males in the study. For the whole patients in the study group, the intervertebral disc height values at the L4-5 level were measured as 12.34 mm, 11.58 mm, and 7.60 mm in the anterior, middle, and posterior localizations, respectively. CONCLUSIONS At the L4-5 level, the height of the disc distances in the herniated group was lower than in the normal group. The Pfirrman score was found to be higher in the herniated group in terms of disc degeneration compared to the normal group.

Abstract
OBJECTIVE Subcutaneous fat tissue thickness (SFTT) is a representative marker of obesity. This study was performed to determine the relationship between SFTT and chondromalacia patella (CP) through routine 1.5-Tesla magnetic resonance imaging (MRI) of the knee. METHODS In this retrospective cross-sectional study, 440 knee MRI scans were re-examined and divided into those with and without CP. A 1.5-Tesla MRI machine with a standard knee coil was used. Prepatellar SFTT (PSFTT) and medial SFTT (MSFTT) were measured on each MRI scan. PSFTT and MSFTT were compared between patients with and without CP. RESULTS Both the PSFTT and MSFTT values were significantly higher in patients with than without CP. Women had significantly higher PSFTT and MSFTT values than men. A statistically significant correlation was found between the PSFTT and MSFTT values and the CP grades. CONCLUSIONS The results of this study indicate an association between SFTT and CP. A positive correlation was also found between SFTT and CP severity.

Abstract
PURPOSE To evaluate the frequency of abdominal computed tomography (CT) findings in patients with coronavirus disease-2019 (COVID-19) and interrogate the relationship between abdominal CT findings and patient demographic features, clinical findings, and laboratory test results as well as the CT atherosclerosis score in the abdominal aorta. METHODS This study was designed as a multicenter retrospective study. The abdominal CT findings of 1.181 patients with positive abdominal symptoms from 26 tertiary medical centers with a positive polymerase chain-reaction test for severe acute respiratory syndrome coronavirus 2 were reviewed. The frequency of ischemic and non-ischemic CT findings as well as the association between CT findings, clinical features, and abdominal aortic calcific atherosclerosis score (AA-CAS) were recorded. RESULTS Ischemic and non-ischemic abdominal CT findings were detected in 240 (20.3%) and 328 (27.7%) patients, respectively. In 147 patients (12.4%), intra-abdominal malignancy was present. The most frequent ischemic abdominal CT findings were bowel wall thickening (n = 120; 10.2%) and perivascular infiltration (n = 40; 3.4%). As for non-ischemic findings, colitis (n = 91; 7.7%) and small bowel inflammation (n = 73; 6.2%) constituted the most frequent disease processes. The duration of hospital stay was found to be higher in patients with abdominal CT findings than in patients without any positive findings (13.8 ± 13 vs. 10.4 ± 12.8 days, P < 0.001). The frequency of abdominal CT findings was significantly higher in patients who did not survive the infection than in patients who were discharged after recovery (41.7% vs. 27.4%, P < 0.001). Increased AA-CAS was found to be associated with a higher risk of ischemic conditions in abdominal CT examinations. CONCLUSION Abdominal symptoms in patients with COVID-19 are usually associated with positive CT findings. The presence of ischemic findings on CT correlates with poor COVID-19 outcomes. A high AA-CAS is associated with abdominal ischemic findings in patients with COVID-19.

Abstract
PURPOSE The inflammation of the heart muscle is referred to as acute myocarditis. Cardiac magnetic resonance imaging (CMR) has become the primary method for a non-invasive assessment of myocardial inflammation. However, there are several drawbacks of CMR. During the last decade, dual energy computed tomography (DECT) has been used in cardiac imaging. The current study aims to assess the efficacy and feasibility of DECT in acute myocarditis and compare the results to CMR. METHODS This prospective study included patients who had myocarditis but no coronary artery pathology. Two observers evaluated the patients for acute myocarditis using DECT and CMR. CMR was performed on 22 patients within 24 hours of DECT, which was administered within 12 hours following the onset of chest pain. Inter-observer agreement was tested with Cohen's Kappa coefficient, and Spearman's correlation was used to examine the possible correlations. A P value of <0.050 was accepted as statistically significant. RESULTS The DECT and CMR agreement was significant for transmural diagnoses, excellent for subepicardial and intramyocardial diagnoses, and perfect for nodular and band-like patterns. CONCLUSION The findings of this study showed that the dark areas on the color-coded iodine map created with DECT were strongly correlated with CMR in acute cases of myocarditis. In addition, DECT is a robust imaging method that can also be used in the diagnosis of acute myocarditis. Furthermore, it provides information about coronary arteries faster and more reliably than magnetic resonance imaging without any limitations.

Abstract
BACKGROUND Hepatic alveolar echinococcosis (HAE) is a serious zoonotic infection that affects humans. It may have a tumor-like appearance at times. Percutaneous treatment of HAE patients is extremely relaxing for them. HAE is a significant human zoonotic infection caused by the fox tapeworm Echinococcus Multilocularis larvae. It possesses the characteristics of an invasive tumor-like lesion due to its infiltrative growth pattern and protracted incubation period. The disease is endemic over central Europe, Asia, and North America.
AIM To characterize HAE patients who were treated percutaneously, their outcomes, and the major technical features of percutaneous treatment in HAE.
METHODS Patients who were treated with percutaneous cyst drainage and/or percutaneous biliary drainage were included in the study. Uncorrected abnormal coagulation values and solid or non-infected HAE with minor necrotic change were excluded.
RESULTS Thirty-two patients underwent percutaneous cyst drainage, two patients underwent percutaneous biliary drainage, and four patients underwent percutaneous biliary drainage alone. Interventional radiology is utilized to drain echinococcal necrosis and abscesses within/without the liver, as well as diseased and clogged bile ducts.
CONCLUSION Percutaneous drainage of cyst contents and/or biliary channels using a minimally invasive technique is a very beneficial. Percutaneous cyst drainage with albendazole therapy improves quality of life in patients who are unable to undergo surgery, even when the mass resolves with long-term treatment.

Abstract
Toxic doses of formaldehyde (FA) can cause oxidative damage and impair energy metabolism. Asprosin (ASP) and subfatin (SUB) are adipokines produced by adipose tissue that help regulate energy metabolism. We investigated the effects of carvacrol (CAR), an antioxidant with hepatoprotective properties, on ASP and SUB in rats exposed to FA using immunohistochemistry and biochemistry. We used 42 male Wistar albino rats divided into six groups of seven: group 1, untreated control; group 2, FA (10 ppm FA by inhalation 8 h/day, 5 days/week); group 3, CAR-20 (20 mg/kg); group 4, CAR-40; group 5, FA (10 ppm FA by inhalation 8 h/day, 5 days/week) + CAR-20 (20 mg/kg); group 6, FA (10 ppm FA by inhalation 8 h/day, 5 days/week) + CAR-40 (40 mg/kg). Levels of ASP and SUB, and total oxidant status (TOS) and total antioxidant status (TAS) in blood and liver tissue were measured using ELISA. ASP and SUB immunoreactivity was assessed using immunohistochemistry. The number of apoptotic cells was determined using the TUNEL method. The number of apoptotic cells in group 2 was increased compared to group 1. TOS in group 2 was increased compared to group 1. The numbers of apoptotic cells and TOS in group 3 were decreased compared to group 1. TOS was decreased in group 6 compared to group 2, but TOS was increased compared to group 1. We found ASP and SUB immunoreactivity in the liver. All alterations were reversed by addition of CAR. It appears that FA disrupts energy metabolism and CAR ameliorates the destructive effects of FA when used at appropriate doses, although CAR might be harmful at high doses.

Abstract
INTRODUCTION The aim of the study was to investigate the relationship between lumbar disc herniation and Goutallier classification (GC), lumbar indentation value, and subcutaneous adipose tissue thickness. METHODS 102 consecutive patients (59 female and 43 male) with lumbar back pain, numbness, tingling, or pain in the lower extremity indicating radiculopathy who had undergone lumbar magnetic resonance imaging (MRI) and had an intervertebral disc herniation in the L4-5 level, were included in the study. 102 patients who have undergone lumbar MRI in the same time period and have no disc herniation were chosen to be the control group and were selected so as to match the herniated group for sex and age. All these patients' scans were re-interpreted regarding paraspinal muscle atrophy (using the GC), lumbar indentation value, and subcutaneous adipose tissue thickness in the L4-5 level. RESULTS The Goutallier score was higher in the herniated group, compared with the non-herniated group (p < 0.001). There was no statistical difference between herniated and non-herniated groups regarding lumbar indentation value (LIV) and subcutaneous adipose tissue thickness (SATT). A Goutallier score of 1.5 provided the highest sensitivity x specificity value to indicate the disc herniation according to the statistical results. The individuals with a Goutallier score of 2, 3, and 4 have 2.87 times more likely to have disc herniation in their MRIs than the ones with a score of 0 and 1. CONCLUSION Paraspinal muscle atrophy seems to be related to the presence of disc herniations. The cut-off value of GC to indicate the disc herniation in this study might be useful to predict the risk for disc herniation regarding the Goutallier score. The LIV and SATT measured in magnetic resonance images were randomly distributed between individuals with herniated and non-herniated groups, and statistically, no relationship was observed between these groups regarding these parameters. IMPLICATIONS FOR PRACTICE The effect of the parameters studied in this research on disc herniations are expected to be an added value to the literature. The awareness of risk factors for intervertebral disc herniations might be used in preventive medicine to predict the risk and understand the tendency of an individual for disc herniations to occur in the future. Further investigations are needed to establish whether there is a causal relationship or correlation between these parameters and disc herniation.

Abstract
BACKGROUND No study on dual energy computed tomography (DECT) has been found in the literature to evaluate possibly fatal cardiac/myocardial problems in corona virus disease 2019 (COVID-19) patients. Myocardial perfusion deficits can be found in COVID-19 patients even without any significant coronary artery occlusion, and these deficits can be shown via DECT with a perfect interrater agreement.
AIM To assess lung perfusion alterations in COVID-19 patients. To our knowledge, no study using DECT has been performed to evaluate possibly fatal cardiac/ myocardial problems in COVID-19 patients. The purpose of this study is to evaluate the role of DECT in the detection of COVID-19-related cardiac diseases.
METHODS Two blinded independent examiners evaluated CT images using the 17-segment model according to the American Heart Association’s classification of the segmentation of the left ventricular myocardium. Additionally, intraluminal diseases and abnormalities in the main coronary arteries and branches were investigated. Following segment-by-segment analysis, perfusion deficiencies identified on the iodine map pictures on DECT were identified.
RESULTS The study enrolled a total of 87 patients. Forty-two of these individuals were classified as COVID-19 positive, and 45 were classified as controls. Perfusion deficits were identified in 66.6% (n = 30) of the cases. All control patients had a normal iodine distribution map. Perfusion deficits were found on DECT iodine map images with subepicardial (n = 12, 40%), intramyocardial (n = 8, 26.6%), or transmural (n = 10, 33.3%) anatomical locations within the left ventricular wall. There was no subendocardial involvement in any of the patients.
CONCLUSION Myocardial perfusion deficits can be found in COVID-19 patients even without any significant coronary artery occlusion. These deficits can be shown via DECT with a perfect interrater agreement. Additionally, the presence of perfusion deficit is positively correlated with D-dimer levels.

Abstract
PURPOSE Although the findings of acute new coronavirus disease (COVID-19) infection on dual-energy computed tomography (DECT) have recently been defined, the long-term changes in lung perfusion associated with COVID-19 pneumonia have not yet been clarified. We aimed to examine the longterm course of lung perfusion in COVID-19 pneumonia cases using DECT and to compare changes in lung perfusion to clinical and laboratory findings. METHODS On initial and follow-up DECT scans, the presence and extent of perfusion deficit (PD) and parenchymal changes were assessed. The associations between PD presence and laboratory parameters, initial DECT severity score, and symptoms were evaluated. RESULTS The study population included 18 females and 26 males with an average age of 61.32 ± 11.3 years. Follow-up DECT examinations were performed after the mean of 83.12 ± 7.1 (80-94 days) days. PDs were detected on the follow-up DECT scans of 16 (36.3%) patients. These 16 patients also had ground-glass parenchymal lesions on the follow-up DECT scans. Patients with persistent lung PDs had significantly higher mean initial D-dimer, fibrinogen, and C-reactive protein values than patients without PDs. Patients with persistent PDs also had significantly higher rates of persistent symptoms. CONCLUSION Ground-glass opacities and lung PDs associated with COVID-19 pneumonia can persist for up to 80-90 days. Dual-energy computed tomography can be used to reveal long-term parenchymal and perfusion changes. Persistent PDs are commonly seen together with persistent COVID-19 symptoms.

Abstract
Diabetes mellitus (DM) is a complicated, globally expanding disease that is influenced by hereditary and environmental variables. Changes in modern society's food choices, physical inactivity, and obesity are significant factors in the development of type 2 DM (T2DM). The association between changes in intestinal flora and numerous disorders, including obesity, diabetes, and cardiovascular diseases, has been studied in recent years. The purpose of this review is to analyze the mechanisms underlying the alteration of the diabetic patients' intestinal flora, as well as their therapeutic choices. Also included is a summary of the anti-diabetic benefits of natural compounds demonstrated by studies. The short-chain fatty acids theory, the bile acid theory, and the endotoxin theory are all potential methods by which intestinal flora contributes to the establishment and progression of T2DM. Due to an intestinal flora imbalance, abnormalities in short-chain fatty acids and secondary bile acids have been found in diabetic patients. Additionally, metabolic endotoxemia with altering flora induces a systemic inflammatory response by stimulating the immune system via bacterial translocation. The agenda for diabetes treatment includes the use of short-chain fatty acids, probiotics, prebiotics in the diet, fecal bacteria transplantation, and antibiotics. Animal studies have proven the antidiabetic benefits of numerous bioactive substances, including Flavonoids, Alkaloids, Saponin, and Allicin. However, further research is required to contribute to the treatment of diabetes.

Abstract
Today, in parallel with the use of imaging modalities increases in all fields, the use of imaging methods in pregnant women is increasing. Imaging has become an integral component of routine pregnancy follow-up. Imaging provides parents with an early opportunity to learn about the current situation, including prenatal detection of anomalies or diseases, etiology, prognosis, and the availability of prenatal or postnatal treatments. Various imaging modalities, especially ultrasonography, are frequently used for imaging both maternal and fetal imaging. The goal of this review was to address imaging modalities in terms of usefulness and safety, as well as to provide demonstrative examples for disorders. And this review provides current information on selecting a safe imaging modality to evaluate the pregnant and the fetus, the safety of contrast medium use, and summarizes major pathological situations with demonstrative sonographic images to assist radiologists and obstetricians in everyday practice.

Abstract
BACKGROUND Coronavirus disease 2019 (COVID-19) is a pandemic caused by the severe acute respiratory syndrome coronavirus in 2019. Although the real-time reverse tr-anscription PCR test for viral nucleic acids is the gold standard for COVID-19 diagnosis, computed tomography (CT) has grown in importance.
AIM To evaluate the sensitivity and specificity of thoracic CT findings of COVID-19 pneumonia according to age groups.
METHODS PCR and CT results from 411 patients were reviewed. The diagnosis of COVID-19 pneumonia was made by three radiologists. Lymphadenopathy, pericardial effusion, pleurisy, pleural thickening, pleural effusion, location features of the lesions, ground glass, consolidation, air bronchogram, vascular enlargement, bronchial dilatation, halo finding, inverted halo sign, nodularity, air bubble, subpleural band (curvilinear density), reticular density, crazy paving pattern, and fibrosis findings were recorded. The patients were divided into nine groups by decades while calculating the sensitivity, specificity, and diagnostic efficacy for CT positivity.
RESULTS The mean age of the cases was 48.1 ± 22.7 years. The CT finding with the highest diagnostic power was ground glass. Vascular enlargement and bronchial dilatation followed ground glass. Peri-cardial effusion was the finding with the lowest diagnostic accuracy. The incidence of lymphadenopathy, pleurisy, pleural thickening, peripheral localization, bilateral, ground glass, vascular enlargement, bronchial dilatation, subpleural band, reticular density, crazy paving appearance, and fibrosis all increased increase significantly with age in patients with positive real-time reverse transcription PCR test.
CONCLUSION There are few publications comparing sensitivity and specificity of thoracic CT findings according to age. In cases of COVID-19 pneumonia, there is an increase in the variety and frequency of CT findings with age, and parallel to this the sensitivity and specificity of the findings increase. COVID-19 cases in the pediatric age group have fewer lung findings than adults, and this situation decreases the diagnostic value of CT in pediatric patients.

Abstract
The present letter to the editor is related to the study titled, “Preoperational diagnosis and management of breast ductal carcinoma in situ arising within fibroadenoma: Two case reports.” Fibroadenoma is the most common benign mass lesion in young females. Based on this study showing that malignancy can develop on fibroadenomas, we want to emphasize that careful sonographic follow-up of fibroadenomas should be done and that each lesion should be followed carefully and separately in cases with multiple fibroadenomas. Additionally, we want to emphasize the critical role of sonographic examination in diagnosing fibroadenoma, the importance of correctly defining benign and malignant sonographic findings, and which lesions should be followed up sonographically and which lesions should be evaluated histopathologically.

Abstract
BACKGROUND The aim of this study was to define clinical evidence supporting that triple rule-out computed tomography angiography (TRO CTA) is a comprehensive and feasible diagnostic tool in patients with novel coronavirus disease 2019 (COVID-19) who were admitted to the emergency department (ED) for acute chest pain. Optimizing diagnostic imaging strategies in COVID-19 related thromboembolic events, will help for rapid and noninvasive diagnoses and results will be effective for patients and healthcare systems in all aspects.
AIM To define clinical evidence supporting that TRO CTA is a comprehensive and feasible diagnostic tool in COVID-19 patients who were admitted to the ED for acute chest pain, and to assess outcomes of optimizing diagnostic imaging strategies, particularly TRO CTA use, in COVID-19 related thromboembolic events.
METHODS TRO CTA images were evaluated for the presence of coronary artery disease, pulmonary thromboembolism (PTE), or acute aortic syndromes. Statistical analyses were used for evaluation of significant association between the variables. A two tailed P-value < 0.05 was considered statistically significant.
RESULTS Fifty-three patients were included into the study. In 31 patients (65.9%), there was not any pathology, while PTE was diagnosed in 11 patients. There was no significant relationship between the rates of pathology on CTA and history of hypertension. On the other hand, the diabetes mellitus rate was much higher in the acute coronary syndrome group, particularly in the PTE group (8/31 = 25.8% vs 6/16 = 37.5%, P = 0.001). The rate of dyslipidemia was significantly higher in the group with pathology on CTA while compared to those without pathology apart from imaging findings of the pneumonia group (62.5% vs 38.7%, P < 0.001). Smoking history rates were similar in the groups. Platelets, D-dimer, fibrinogen, C-reactive protein, and erythrocyte sedimentation rate values were higher in COVID-19 cases with additional pathologies.
CONCLUSION TRO CTA is an effective imaging method in evaluation of all thoracic vascular systems at once and gives accurate results in COVID-19 patients.

Abstract
BACKGROUND Magnetic resonance imaging (MRI) with multiparametric dynamic contrast plays a critical role in the assessment of breast lesions. Dynamic curves are a critical parameter in determining the benign or malignant nature of lesions. Dynamic curves of type 1 are known to represent benign masses, while dynamic curves of type 3 are known to identify malignant masses. Type 2 dynamic curves have a sensitivity of 42.6% and specificity of 75% for malignancy detection.
AIM To investigate the pathological diagnosis of lesions with type 2 dynamic curves.
METHODS We evaluated breast MRI examinations performed between 2020 and 2021 retrospectively and included lesions with type 2 dynamic curves. We included 38 lesions from 33 patients. The lesions were evaluated for their pathological diagnosis and morphological characteristics.
RESULTS Twenty-six lesions were malignant, while twelve were benign. The most frequently encountered benign lesion (7/12, 58.3%) was sclerosing adenosis, while the most frequently encountered malignant diagnosis was invasive ductal cancer. The presence of a type 2 dynamic curve had a sensitivity of 40.2% and specificity of 73.4% for predicting malignancy. By combining type 2 curves and morphological features, the sensitivity and specificity were increased.
CONCLUSION The high rates of malignancy detected histopathologically among patients with type 2 dynamic curves in our study are remarkable. Type 2 dynamic curves can be detected in benign breast masses, especially in sclerosing adenosis cases. Considering morphological features can increase the diagnostic accuracy in cases with type 2 dynamic curves.

Abstract
BACKGROUND Total exposure to ionizing radiation has nearly doubled in the last two decades. This increase is primarily due to increased computed tomography (CT) exposure. Concerns have been raised about the risks associated with patients' exposure to medical imaging radiation, which can increase a person's lifetime risk of developing cancer. Preventing unnecessary examinations becomes critical at this point. To avoid unnecessary examinations, it is necessary to understand the demanding process.
AIM To ascertain clinicians' awareness of and reasons for requesting a CT examination.
METHODS We developed an online questionnaire that included 20 questions about clinicians' awareness of radiation safety and their reasons for requesting a CT examination, as well as demographic information such as age, gender, and year of medical practice experience. Additionally, we asked participants the number of CT scans requested in a month, the patients' questions and approaches about the imaging method, the effect of the patient's previous imaging history on the current imaging request, whether they believed that they had sufficient information about radiation doses, and whether they requested CT without an indication. We administered the questionnaire to clinicians from a variety of different professions in four different cities.
RESULTS A total of 195 clinicians participated. Internal medicine specialists were the most crowded group (38/195, 19.5%). Mean age of the population was 33.66 ± 5.92 years. Mean year of experience was 9.01 ± 5.96. Mean number of requested CT scans in a month was 36.88 ± 5.86. Forty-five (23.1%) participants stated that they requested CT scans without clinical indication. The most common reasons for CT scan requests were work load, fear of malpractice, and patient demand/insistence.
CONCLUSION CT scan requests are influenced by a variety of factors, both internal and external to the doctors and patients. Raising awareness of radiation safety and reducing fear of malpractice by limiting the number of patients per physician may result in a reduction in unnecessary CT examinations and ionizing radiation exposure.

Abstract
OBJECTIVE Cervical Inlet Patch (CIP) is an interesting entity that is little known and often neglected by endoscopists. It has always been reported as less than expected. In this article, for the first time in the literature, we want to measure the true prevalence of CIP in a center dealing with specific esophageal diseases. PATIENTS AND METHODS From October 2020 to October 2021, a total of 283 patients, aged 15-95 years, with mainly dyspeptic and reflux-like complaints were included in this study. All endoscopic procedures were performed carefully by a single endoscopist. Patients were examined for any possible presence of CIP, with adequate sedation and time. RESULTS The prevalence of CIP, which was the primary aim of our study, was detected at a rate of 14.8%. Most CIP was observed as a single lesion (73.8%), and many of them (45.2%) were larger than 10 mm. Plenty of patients had upper endoscopy due to dyspeptic complaints, but only 2.5% of them presented with a preliminary diagnosis of laryngeal reflux. CONCLUSIONS The true CIP prevalence is higher than reported before. Our result is the highest prevalence rate of CIP was detected in Turkey. In this regard, data coming from centers dealing with specific esophageal diseases may be more reliable and true.

Abstract
We read with interest the review by Teng et al, who summarized the current approach to the diagnosis and treatment of acute appendicitis (AA). Also, the article summarizes the clinical scoring systems very effectively. In one of the previous studies conducted by our research group, we showed that the use of the Alvarado score, ultrasound and C-reactive protein values in combination provides a safe confirmation or exclusion of the diagnosis of AA. Computed tomography is particularly sensitive in detecting periappendiceal abscess, peritonitis and gangrenous changes. Computed tomography is not a good diagnostic tool in pediatric patients because of the ionizing radiation it produces. Ultrasound is a valuable diagnostic tool to differentiate AA from lymphoid hyperplasia. Presence of fluid collection in the periappendiceal and lamina propria thickness less than 1 mm are the most effective parameters in differentiating appendicitis from lymphoid hyperplasia. Although AA is the most common cause of surgical acute abdomen, it remains an important diagnostic and clinical challenge. By combining clinical scoring systems, laboratory data and appropriate imaging methods, diagnostic accuracy and adherence to treatment can be increased. Lymphoid hyperplasia and perforated appendicitis present significant diagnostic challenges in children. Additional ultrasound findings are increasingly defined to differentiate AA from these conditions.

Abstract
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.

Abstract
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.

Abstract
Background
Invasive mole is a trophoblastic disease (GTD) caused by trophoblast cells invading the myometrium during pregnancy. The GTD range also includes mole hydatidiform, choriocarcinoma, and placental site trophoblastic tumor (PSTT). Invasive moles are most common following molar pregnancies; however, they can even rarely occur after a full-term birth. Despite the fact that pathology is the only way to make a clear diagnosis, clinic and radiologic evaluation can be helpful. We wanted to highlight a rare incidence of invasive mole following a healthy full-term delivery in this case.
Case presentation
A 28-year-old female patient presented with intermittent prolonged severe vaginal bleeding for 2 weeks after a term healthy vaginal delivery. In workup, beta human chorionic gonadotropin levels (b-hCG) value was 7540 mIU/ml. After suspicion of gestational trophoblastic neoplasm (GTN), the patient was sent to ultrasonography (US) and magnetic resonance imaging (MRI). GTN was confirmed by radiological and clinical findings, and a conclusive diagnosis of an invasive mole was made histopathologically.
Conclusion
Invasive mole should be considered in the differential diagnosis in patients with postpartum bleeding and a persistently high b-hCG level after a healthy term delivery.

Abstract
Intrathyroidal ectopic thymus (IET) is defined as an ectopic thymus tissue that is generally found incidentally and rarely in the thyroid gland in the pediatric group. It occurs as a result of disruption of the embryological migration path and the settling of the thymus tissue into the thyroid gland. In the differential diagnosis, it is mostly confused with thyroid nodules. Although thyroid nodules are less common in children than adults, the rate of malignancy is much higher. Therefore, knowing the general ultrasound findings of IET better may prevent unnecessary invasive attempts and surgical procedures. In this article, we tried to compile the key imaging findings of IET.

Abstract
Introduction Attention deficit hyperactivity (ADHD) disorder is a common childhood neurodevelopmental disorder, and Methylphenidate (MPH) is a first-line therapeutic option for treating ADHD.However, how brain complexity and entropy changes with methylphenidate treatment the clinical implications of possible changes in entropy and the clinical implications of possible changes in entropy have yet to be studied. Objectives This study aimed to reveal how the MPH treatment affects the complexity in the brain of children with ADHD by entropy-based qEEG analysis. In addition, the presence of the relationship between possible neurophysiological changes to be detected with clinical variables and how they are two other important questions of this study to be answered. Methods During eyes-open resting, EEG signals were recorded from 25 boys with ADHD-combined type before MPH administration and at the end of the 1st month of the treatment. Approximate entropy (ApEn), sample entropy (SampEn), permutation entropy (PermEn) were used to analyse. Results ![]() ![]()
A statistically significant decrease in entropy level was found with MPH treatment in the F4 channel according to approximate entropy (ApEn) and sample entropy (SampEn) analysis (p<0.05). In addition, according to permutation entropy (PermEn) analysis, the decrease in entropy with MPH treatment in the regions indicated by F3, F4, P4, T3, T6, and O2 channels was found to be statistically significant (p <0.05). Conclusions This is the first study to investigate how MPH treatment affects the complexity in the brain of children with ADHD. Entropy-based qEEG analysis may be a new method that can be used in diagnostic, clinical and prognostic predictions in ADHD. Disclosure No significant relationships.

Abstract
OBJECTIVES The aim of this study is to assess magnetic resonance imaging (MRI), diffusion-weighted imaging (DWI), T2-weighted image (T2WI), and apparent diffusion coefficient (ADC) maps' threshold values before computed tomography (CT)-guided transthorasic biopsy in solitary pulmonary nodules (SPN) by describing tumoral cell density. MATERIALS AND METHODS Patients who had SPN were prospectively evaluated with MRI (T1WI, T2WI) and DWI (b=0, b=500, b=1000).The ADC maps were created for each patient. Before the biopsy, lesion muscle ratios (LMR) at T2WI, ADC value, and lesion spinal cord ratio at each b values were noted. The measurements were correlated with the histopathological results. RESULTS A total of 53 patients were included in the study: 30.2% (n=16) were female, and 69.8% (n=37) were male. Among them, 17 lesions (32.1%) were benign, and 36 lesions (67.9%) were malignant. The age varied between 40 and 82 years, with a mean of 61.7±9.1 years. The SPN diameters were between 10 and 30 mm, and the median was 24 mm. The LSR0 and LMR values were not statistically significant in detecting malignancy. LSR500 >0.53 value can predict malignancy with 100% sensitivity and 70.6% specificity. LSR1000 >0.53 can predict malignancy with 88.9% sensitivity and 88.2% specificity. Setting the cut-off value at 0.9×10-3, the ADC values had a sensitivity of 72.2% and a specificity of 88.2% for predicting malignancy. CONCLUSION For SPN follow-up, a new following-up protocol can be safely established using DWI and ADC mapping. Using these MRI parameters might decrease unnecessary biopsy rates and complications of biopsies.

Abstract
Background/aim: Head injuries are commonly seen in the pediatric population. Noncontrast enhanced cranial CT is the method of choice to detect possible traumatic brain injury (TBI). Concerns about ionizing radiation exposure make the evaluation more challenging. The aim of this study was to evaluate the effectiveness of the Pediatric Emergency Care Applied Research Network (PECARN) rules in predicting clinically important TBI and to determine the amount of medical resource waste and unnecessary radiation exposure.Materials and methods: This retrospective study included 1041 pediatric patients presented to the emergency department. The patients were divided into subgroups of "appropriate for cranial CT", "not appropriate for cranial CT" and "cranial CT/observation of patient; both are appropriate". To determine the effectiveness of the PECARN rules, data were analyzed according to the presence of pathological findings Results: "Appropriate for cranial CT" results can predict pathology presence 118,056-fold compared to the "not appropriate for cranial CT" results. With "cranial CT/observation of patient; both are appropriate" results, pathology presence was predicted 11,457-fold compared to "not appropriate for cranial CT" results.Conclusion: PECARN rules can predict pathology presence successfully in pediatric TBI. Using PECARN can decrease resource waste and exposure to ionizing radiation.

Abstract
IntroductionSexual dysfunctions are more common in individuals with psychotic disorders and has a major impact on both quality of life and compliance.ObjectivesThe purpose of this study is to investigate whether a relationship between sexual dysfunction and level of treatment compliance in individuals with psychotic disorders.MethodsThe sample group of the study consisted of 173 in-patients who agreed to participate were selected by random sampling method. The permission was obtained from the hospital's ethics committee. In this study, to assess the sexual functionality Golombok-Rust inventory of sexual satisfaction male and female form and to assess the treatment compliance; medical treatment compliance rate scale is used.ResultsWhen sexual problems and treatment compliance compared to gender, subscales of satisfaction (t = 4,423, P = 0.000), avoidance (t = 3.348, P = 0.001), touch (t = 2.165, P = 0.032) and overall total (t = 4.015, P = 0.000), although a statistically significant difference was found, there were no differences in treatment compliance. Aditionally, there is no relation between sexual problems and treatment compliance in men. It is also found that there is a weak negative statistical relation amongst treatment compliance and communication (r = −0.244, P = 0.027), avoidance (r = −0.270, P = 0.014), anorgasmia (r = −0.253, P = 0.022) and overall total (r = −0.249, P = 0.024) in women. According to these findings while sexual problems increase, treatment compliance decreases.ConclusionsThe level of compliance to the treatment and subscales of sexual problems; satisfaction, avoidance, and touch mean scores differ from each other. There was a weak negative correlation in between Women's compliance and sexual problems.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
Reactive oxygen species are believed to be involved in the development of sepsis. Plant-derived phenolic compounds are thought to be possible therapeutic agents against sepsis because of their antioxidant properties. Rosmarinic acid (RA) is a phenolic compound commonly found in various plants, which has many biological activities including antioxidant activity. The aim of this study was to investigate the effects of RA on sepsis-induced DNA damage in the lymphocytes and liver and kidney cells of Wistar albino rats by alkaline comet assay with and without formamidopyrimidine DNA glycosylase protein. The oxidative stress parameters such as superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities and total glutathione (GSH) and malondialdehyde (MDA) levels in the liver and kidney tissues and an inflammatory cytokine, tumor necrosis factor α (TNF-α) level in plasma were also evaluated. It is found that DNA damage in the lymphocytes, livers, and kidneys of the RA-treated rats was significantly lower than that in the sepsis-induced rats. RA treatment also decreased the MDA levels and increased the GSH levels and SOD and GSH-Px activities in the livers and kidneys of the sepsis-induced rats. Plasma TNF-α level was found to be decreased in the RA-treated rats. It seems that RA might have a role in the attenuation of sepsis-induced oxidative damage not only by decreasing the DNA damage but also by increasing the antioxidant status and DNA repair capacity of the animals.

Abstract
Aflatoxins, the secondary metabolites produced by species of naturally occurring Aspergilli, are commonly found in food such as cereals, dried fruits and juice, wine, beer and spices. They are hepatotoxic and are well known human carcinogens based on evidence from human studies. Aflatoxins are an environmental risk factor for the development of hepatocellular carcinoma (HCC). Chronic hepatitis B-infected patients are at increased risk of cirrhosis, hepatic failure and liver cancer. This study was designed to determine the serum aflatoxin B1 (AFB1 ), aflatoxin B2 (AFB2 ), aflatoxin G1 (AFG1 ) and aflatoxin G2 (AFG2 ) concentrations using high-pressure liquid chromatography (HPLC) in hepatitis B-infected patients with or without cirrhosis and liver cancer, alongside healthy controls in Balıkesir, Turkey. The mean AFB1 and total AF levels in patients without liver cancer and cirrhosis were significantly higher than healthy controls. The mean AFB1 and total AF levels in patients with chronic hepatitis B and HCC were significantly higher than infected patients with or without cirrhosis. These results suggest that patients with chronic hepatitis B who are exposed to AFs are at increased risk for developing HCC, which might be prevented by reducing consumption of contaminated foods.
