Background/aim: There is no study in the literature in which only chest computed tomography (CT) findings of deceased cases obtained at admission were examined, and the relationship between these findings and mortality was evaluated. Materials and methods:In this retrospective study, a total of 117 deceased patients with COVID-19 infection confirmed by positive polymerase chain reaction and undergone chest CT were enrolled. We evaluated initial chest CT findings and their relationship, location, prevalence, and the frequency with mortality. Results:The mean age of patients was 73 ±18 years; 71 of all patients were male and 46 were female. The predominant feature was pure ground-glass opacity (GGO) lesion (82.0%), and 59.8% of cases had pure consolidation. There was no cavitation or architectural distorsion. Pericardial effusion was found in 9.4% the patients, and pleural effusions were found in 15.3% of them. Mediastinal lymphadenopathy was only 11.9% in total. Conclusion:In deceased patients, on admission CTs, pure consolidation, pleural and pericardial effusion, mediastinal LAP were more common than ordinary cases. It was these findings that should also raise the concern when they were seen on chest CT; therefore, these radiologic features have the potential to represent prognostic imaging markers in patients with COVID-19 pneumonia.

Amaç: Çalışmamızda perkütan kolesistostominin (PK) hastaların klinik ve laboratuvar bulgularına etkisini araştırdık. Gereç ve Yöntem: Çalışmamıza Şubat 2017 ile Kasım 2018 tarihleri arasında PK yapılan 36 hasta dahil edildi.Hastaların işlem öncesi ve sonrası klinik ve laboratuvar bulguları retrospektif olarak tarandı. Bulgular: Hastalarımızda rekürrens görülmemiştir. PK işlemi ile ilişkili mortalite ya da komplikasyon izlenmemiştir. Kateterin takılı kalma süresi 50,2 ± 26,1 gün, hastane yatış süresi 7,5 ± 5,2 gün olarak belirlenmiştir. Total bilirubin değeri ve beyaz küre sayısı yüksek olan hasta sayısında işlem öncesi ve sonrası arasında istatistiksel olarak anlamlı fark saptanmıştır. ALT, ALP, CRP, beyaz küre sayısı, total ve direkt bilirubin parametrelerinin işlem öncesi ve sonrası değerleri arasında da istatistiksel olarak anlamlı fark saptanmıştır. Tokyo kılavuzu evresi ile yoğun bakım ihtiyacı arasında istatistiksel olarak anlamlı fark saptanmış olup yoğun bakımda tedavi gösteren tüm hastalar evre 3’tür.PK sonrasında cerrahiye giden hastaların yaş ortalaması diğer gruba göre daha yüksektir. Sonuç: İşlem sonrasında beyaz küre sayısı ve CRP değerinde anlamlı düşüş ve hastaların çoğunluğunda klinik düzelme görülmesi PK’nin A.K kaynaklı enflamatuar süreçleri olumlu yönde etkilediğini göstermektedir. Çalışmamızda işlem sonrasında ALT ve ALP değerlerinde anlamlı düşüş saptanmış olup, bu bulgu bildiğimiz kadarıyla literatürde ilk kez tanımlanmıştır.

Magnetic resonance imaging (MRI)-induced anxiety is not infrequent with a reported incidence as high as 37% and the rate of failed MRI imaging due to claustrophobia ranges between 0.5% and 14.5%. The objective of this study was to evaluate the quality and reliability of YouTube TM videos on MRI claustrophobia. MethodsSixty-five videos were included in the final analysis. Video information analyzed included video length (minutes), video content, qualification of the video uploaders, time of upload, time since upload, the number of total views and the mean daily views, and like counts. We divided the videos according to the uploaders into professional and non-professional groups and further grouped the videos as useful and misleading. Data obtained from the videos were evaluated with three tools including subjective evaluation, Quality Criteria for Consumer Health Information (DISCERN), and Global Quality Scale (GQS) tools. ResultsThe mean video duration was found as 4.14±4.45 minutes. The mean view count was 104.59±408,788.68 and the mean like count was found as 272.55±1096.25. Seventeen (26.15%) videos were uploaded by professionals and 48 (73.85%) by non-professionals. Twenty-eight (43.08%) of the videos were useful and 37 (56.92%) were useless. The mean DISCERN and GQS scores were statistically significantly higher in the professional videos compared to the non-professional videos and in useful videos compared to non-useful videos (for all, p<0.001). ConclusionA majority of the YouTube TM videos concerning MRI claustrophobia were uploaded by non-professionals. Physicians and other healthcare personnel should be encouraged to provide useful and accurate videos and to direct patients appropriately.

Aim: Coronavirus disease 2019 (COVID-19) is an unprecedented cause of pandemics affecting all segments of society. It is not known whether hemodialysis patients form a different patient group in terms of susceptibility to COVID-19 infection or severe disease. In this study, thorax computed tomography (CT) findings were evaluated in hemodialysis patients diagnosed with COVID-19 infection during the pandemic period. Material and Methods: CT findings of 32 hemodialysis patients diagnosed with COVID-19 with real-time polymerase chain reaction or thorax CT examination were evaluated retrospectively. Radiological findings were classified as ground glass, consolidation, mixed type involvement (ground glass and consolidation), crazy paving appearance, interlobular septal thickening, nodule, halo-reverse halo finding, air bronchogram finding, subpleural curvilinear opacities and tree-in-bud views. Results: A total of 32 patients were included in the study. Twenty-one (65.6%) of the patients were male and 11 (34.4%) were female. The mean age was 67.5±8.5 years. All patients had chronic kidney failure. Thorax CT examination revealed ground-glass opacities in 14 (43.8%) patients, consolidation in 3 (9.4%) patients, and mixed type involvement (ground-glass opacities and consolidation) in 15 (46.9%) patients. The accompanying CT findings were pleural effusion in 23 (71.9%) patients, subpleural curvilinear opacities in 13 (40.6%) patients, bronchial wall thickening in 11 (34.4%) patients, lymphadenopathy in 7 (21.9%) patients, bronchiectasis in 4 (12.5%) patients and pleural thickening in 4 (12.5%) patients. Conclusion: When hemodialysis patients are infected with COVID-19 infection, they differ significantly from other COVID-19 patients in terms of symptoms, clinical course, and prognosis, as well as imaging findings.

Aim: The aim of this study was to evaluate the efficacy of transarterial chemoembolization (TACE) with drug-eluting beads in hepatocellular carcinoma (HCC). Material and Methods: Twenty-nine patients with HCC who were treated with TACE with drug-eluting beads between 2019 and 2021 were included in the study. The success of the TACE procedure was evaluated using pre- and post-operative contrast-enhanced computed tomography/magnetic resonance images. Patient characteristics, embolizing-bead sizes, procedure-related complications, and pre- and post-procedure alpha-fetoprotein (AFP) levels were recorded. Results: The mean age of the patients was 65.6±10.4 years, and the objective response rate was 17.2% (5/29). 100-300 μm particles were used in 11 (37.9%) patients, and 300-500 μm particles were used in 18 (62.1%). The median target lesion number was 1 (range, 1-6). Six (20.7%) patients had non-target lesions. There were newly developed lesions in four (13.8%) patients. A significant decrease was found in the median target lesion size after (41; range, 0-116 mm) the procedure compared to the pre- (42; range, 22-188 mm) procedure (p&lt;0.001). A significant difference was found between the median AFP levels before (343; range, 1.44-2000 ng/mL) and after (52; range, 0.95-1435 ng/mL) the procedure (p&lt;0.001). Conclusion: Since most patients with HCC are diagnosed in the intermediate stage, curative treatment is not possible. TACE is an important treatment option for the local control of the disease in this patient group. However, the success of TACE treatment may vary depending on the cancer stage, number of patients, follow-up period, and type and size of the microsphere used.
