Radiological features of round pneumonia in children: 10 years of experience
Authors: UCAN Berna , ÇINAR Hasibe Gökçe 
Published: March 2022

Aim: Round pneumonia (RP) is a type of pneumonia that appears round on imaging studies and usually occurs in children. Although round pneumonia is a well-known clinical condition, few publications available in the literature describing the imaging findings and features of round pneumonia. The purpose of the review was to evaluate the chest radiographs, chest ultrasonography and CT findings associated findings of round pneumonia as compared to the published literature.
Material and Method: 65 children who were diagnosed with round pneumonia in our hospital between December 2010 and July 2020 were included in our study. Initial chest radiographs and CT scans were evaluated for lesion parameters: number, margin, opacity, size, location, and hilar LAP and air bronchogram accompaniment. Follow-up chest radiographs were evaluated for temporal variation (resolution or progression to lobar pneumonia). The findings of the patients who underwent chest ultrasonography were recorded.
Results: The mean age of the 65 children with round pneumonia included was 6.2 years and their ages ranged from 9 months to 16 years. Evaluation of chest radiographs showed one lesion in each of 63 children (96%, 63/65) and two lesions in two children (4%, 2/65). Lesion margins were sharp in 84% (55/65) and the mean diameter of lesions was 2,5 cm with a range of 1.5–9.5 cm. On the radiograph, the opacity of round pneumonia was low (60%, 39/65) and hilar lymphadenopathy was detected in 1 out of 5 patients (20%, 13/65). The location of the lesion tended to be posterior (51%, 33/65) and upper lobe (54%, 35/65). On chest ultrasonography, consalidation was seen in 8 patients, consalidation and pleural effusion were seen in 3 patients. CT images were available in 11 (17%) children. Pleural thickening or satellite lesions were not observed in any of the patients on tomography. Follow-up radiographs tended to show resolution in 95% (62/65) and progression to lobar pneumonia in 4.6% (3/65). 1 patient progressed to lobar pneumonia and died. 2 patients developed cavitary pneumonia.
Conclusion: Round pneumonia is a benign type of pneumonia that is mostly seen in children due to its physiopathology. Most patients with RP recover clinically and radiologically after antibiotic therapy. Although there are many diseases in the differential diagnosis, knowing the radiological features facilitates the diagnosis and prevents unnecessary diagnostic and imaging studies.

Published: March 2022

Aim: The aim of this paper is to survey the COVID-19 research articles in Q1 ranked high SJR index journals according to the SCImago journal rank indicator.
Material and Method: The study was carried out on the website named "https://www.scimagojr.com". The search was conducted by selecting the criteria “medicine”, “pathology and forensic medicine”, “all regions/countries”, “journals”, and the “2020” as the year. Only 50 scientific journals met these criteria. COVID-19-related and unrelated research articles published in these journals were manually scanned. Review articles, book reviews, conferences, commentaries, case reports, mini reviews, short communications, letters to the editor were not included in the study. COVID-19 related research articles were divided into groups in terms of antemortem and postmortem type of the study by reviewing the abstract of the studies and also grouped according to the country of first author and countries of all authors.
Results: A total of 3906 research articles published in 50 journals with Q1 SJR index over 0.887 were investigated. Of these 3906 research articles, 40 of them were related to COVID-19. 31 of these 40 COVID-19 related research articles were antemortem and 9 were postmortem studies. Among these 40 COVID-19 related scientific articles, the first author of publications belonged to 12 countries. United States, Australia, China, and Italy were found to be the most productive countries for published research articles on COVID-19 in selected high SJR index journals. The United States was the country with the highest number of first authors with 15 articles. China was the country with the highest number of multinational author list research articles.
Conclusion: We believe that the number and content of studies conducted in these high-quality scientific journals on COVID-19 make important contributions and understanding in the fields of disease transmission, disease prevention, course and severity of symptoms, pathophysiology, molecular characteristics, and treatment approach processes.

Published: March 2022

Aim: In our country, the stress experienced by physicians due to their working conditions and intense workload plays a role in the formation of medical errors, therefore, physicians want to protect themselves from litigation processes with defensive medicine practices. The aim of our study is to evaluate the effects of defensive medicine practices on health service delivery.
Material and Method: In our study, the knowledge and attitudes of a total of 175 dentists working in Dicle University Faculty of Dentistry and Diyarbakir Oral and Dental Health Hospital and its affiliated centers about defensive medicine practices, age, physician (service) duration, gender, institution, title and specialty areas, if any, the relationship was examined using the knowledge level measurement questionnaire. While performing statistical analysis, Chi-square Test was used for comparisons.
Result: It was observed that 32% of the physicians in the 26-40 age group, who constitute the vast majority (71.4%) of the participants in the study, were not aware of the concept of defensive medicine. It was found that 36.6% of the participants, 84.4% of those with 1-5 years of medical experience, and 83.3% of the specialty students with the largest share, with the largest share, did not know this concept at all.
Conclusion: It is found that most of the physicians do not have the necessary knowledge about medical errors and malpractice. While the level of knowledge is increased through in-service training programs, seminars and conferences about malpractice, medical errors, defensive medicine practices, the experience of experienced physicians can be used in preventing and solving problems.

Published: March 2022

Introduction: Chronic obstructive pulmonary disease (COPD) is a debilitating disorder that restricts the physical activity of patients who are deprived of sunlight, which is a source of vitamin D. The purpose of this study was to assess the relationship between vitamin D and the frequency of exacerbation and hospitalization among patients with COPD.
Material and Method: In the main analysis, 303 patients with COPD (stage GOLD A to D) were included in a retrospective cohort study in Turkey. Serum levels of vitamin D (25-hydroxyvitamin D) were measured in 303 patients with COPD and were associated with pulmonary function, AECOPD frequency and hospitalization in the previous year. Results: For COPD patients, the mean reference level of 25 hydroxyvitamin D in serum was 12.5 ng/dL. In comparison to patients with a serious 25-hydroxyvitamin D deficiency (< 10 ng/dL, n=119 [39,3%]), patients with a moderate deficiency (10-19.99 ng/dL, n=100 [33%]), inadequate levels (20-29.99 ng/dL, n=49 [16,2%]) presented a different risk of exacerbation (incidence rate ratio, 2.3 [95% CI, 1.9-2.6], 1.6 [95% CI, 1.2-2.0], and 0.8 [95% CI, 0.3-1.2] respectively). In patients with desirable levels (> 30 ng/dL, n=34 [11,2%]), the risk was lower but not significant (incidence ratio, 0.7 [95% CI, 0.2-1.2]. In COPD patients, 25-hydroxyvitamin D rates are low correlated with 1-s forced expiratory volume (FEV1) (r=0.187, p=0.0013).
Conclusion: 25-hydroxyvitamin D deficiency is a frequent occurrence in COPD and is correlated with the frequency of exacerbation and hospitalization in COPD patients.

Published: March 2022

Aim: Common causes of thyrotoxicosis are hyperthyroidism and destructive thyroiditis. Hyperthyroidism is a condition characterized by high serum thyroid hormone levels as a result of over-synthesis of thyroid hormones, the most common causes of which are Graves' disease (GD) and toxic nodular goiter (TNG). Subacute thyroiditis (SAT) causes thyrotoxicosis due to the circulating thyroid hormones of destructive thyroiditis. Differential diagnosis is important because GD, TNG and SAT treatment approaches are different. The aim of this study was to analyze whether it is possible to make a differential diagnosis for these conditions by examining free thyroid hormones, fT3/fT4 ratio, fT3 index/TSH index (fT3I/TSHI) ratio and Free Thyroid Hormone Index (FTHI).
Material and Method: This retrospective study included 150 patients who were diagnosed with GD, TNG and SAT. The fT3 index (fT3I) was calculated as the ratio between the fT3 value and the fT3 upper limit of normal value (fT3I=fT3/4 pg/ml). The fT4 index (fT4I) was calculated as the ratio between the fT4 value and the fT4 upper limit of normal value (fT4I=fT4/1.23 mg/dl). The TSH index (TSHI) was calculated as the ratio between TSH value and the TSH lower limit of normal limit (TSHI=TSH/0.38 mIU/L). The FTHI index was calculated using the formula of (fT3 level/fT3 upper limit of normal) / (fT4 level/fT4 upper limit of normal).
Results: The fT3, fT3/fT4 ratio and FTHI were found to be higher in hyperthyroid patients compared to subacute thyroiditis patients. fT4 and fT3I/TSHI levels were similar in hyperthyroid patients and SAT patients (p=0.49, p=0.11, respectively ). The cut-off level of FTHI for hyperthyroidism was determined as 0.97 with sensitivity of 75% and specificity of 76.3% (AUC=0.833, p< 0.001). When hyperthyroidic patients were divided into two groups as GD and TNG, no significant difference was found in fT3/fT4 ratio (p:0.99). The fT3 (p

Authors: İNAN Osman , ŞAHİNER Enes 
Published: March 2022

Aim: We planned this study to examine whether the measures taken against COVID-19 infection during the pandemic and COVID-19 vaccination process raise awareness about influenza and pneumococcal vaccines for patients in the risk group.
Material and Method: Patients over the age of 18 who were in the risk group according to CDC and had chronic diseases requiring influenza and pneumococcal vaccination were included in the study. A questionnaire consisting of seven questions was applied to all volunteers, showing their clinical demographic findings, their vaccination history, and whether the pandemic and COVID-19 vaccination processes contributed to the vaccination processes.
Results: It was found that 42.5% of the entire population had had a preventive vaccine before. With the COVID-19 pandemic, it was determined by the survey that 74.7% of the people would get their preventive vaccinations regularly from now on. After that, it was determined that the pandemic and COVID-19 vaccination processes were effective at a rate of 57.9% in the formation of this idea in the group that wanted to get a preventive vaccine.
Conclusion: As a result, the idea of having a preventive vaccination compared to the period before the pandemic increased during the pandemic period in relation to the events experienced in the pandemic. In this, it was determined that catching COVID-19 infection, hospitalization and intensive care unit admission and COVID-19 vaccination campaigns were effective in the cases in the risk group.
Forensic-medical retrospective analysis of cardiovascular injuries admitted to the emergency department
Authors: ÖNER Bedirhan Sezer , AS Ahmet Kağan 
Published: March 2022

Aim: Vascular and cardiac injuries are rare cases compared to other traumas in terms of admission rates to emergency services. Vascular emergencies secondary to trauma are among 1-2.5% of all trauma patients admitted to the emergency department. In addition, the admission rate of heart injuries is around 1%. With this study, we will analyze and interpret cardio-vascular injuries, which are rare compared to other traumas, from a forensic-medical aspect.
Material and Method: This study is a retrospective cohort study using data from our hospital's automation and archive system. Patients who developed iatrogenic trauma, had solid organ injury in addition to their existing injury, were brought to the emergency room as deceased, and patients who came to the emergency room with cardio-pulmonary resuscitation were not included in the study. A total of 411 cases, 88 cardiac injuries and 323 vascular injuries, aged 16-82 years were included in the study.
Results: In the 5-year analysis, the rate of life-threatening injuries due to cardiac and vascular injuries among cardiovascular emergencies is 22%. 88 patients with cardiac injury were included in this study.18 (20.5%) of the patients were female and 70 (79.5%) were male. The most common injury sites were upper extremity (43.7%), lower extremity (25.7%), thorax (21.4%), abdomen-pelvic region (4.1%), head-neck (2.6%), multiple vascular injury (2.1%), respectively.
Conclusion: Cardiovascular injuries are among the traumas with high mortality and morbidity. It is important that the cases consulted to cardiovascular surgery in the emergency department are forensic cases and that the forensic reports of these cases are carefully prepared.

Published: March 2022

Aim: Vibration-controlled transient elastography (VCTE) is an accurate technique that has an increasing use. In recent years, VCTE was started to use in predicting spleen stiffness (SS). Portal vein pressure and flow have an impact on SS and in previous studies it was used to predict portal hypertension, esophageal varices. In this study, our aim was to evaluate the SS measurements in healthy population and its correlation with age, sex, liver stiffness measurement (LSM), continued attenuation parameter (CAP) and body mass index (BMI).
Material and Method: We enrolled healthy volunteers who were agreed to participate to the study and collected age, sex, smoking history, alcohol consumption, body mass index before the VCTE procedure. Liver and spleen elastography were performed to all patients by VCTE.
Results: A total of 97 participants were enrolled to the study, 15 patients were excluded and 82 patients included for the final analysis. There was no significant difference in SS, liver stiffness measurement LSM, CAP and BMI between females and males. There was no correlation between age and SS. There was a weak correlation between SS and LSM, SS and CAP and no correlation was found between SS and BMI.
Conclusions: SS had a weak correlation with LSM and CAP but not with BMI, age and sex. There is no extra-large probe use in SS measurement and it was a challenge in participants with increased submucosal fat thickness. Multiple and repeatable studies needed to set an accurate cut-off point and evaluate the factors that impact on SS in healthy individuals.
