Recently, several inflammatory markers, including the uric acid to HDL cholesterol ratio (UHR), triglyceride/HDL (THR), systemic index (SII), and C-reactive protein albumin (CAR), have been reported be associated with conditions. However, their collective role in sacroiliitis has not extensively studied. This study aims investigate general characteristics markers patients without sacroiliitis, observe any differences these parameters subjects active chronic sacroiliitis. Patient who showed...

The objective of this study is to assess the hepatic/renal and splenic/renal echointensity ratios in ultrasonography patients with without diabetic nephropathy. This retrospective included diabetes mellitus who underwent ultrasound examinations at our hospital between January 2023 May 2023. Ultrasound done renal cortical echogenicity cortico-medullary differentiation by using B-mode ultrasonography. echo intensity were compared among groups (diabetic nephropathy nephropathy). group exhibited...

Because of the close anatomical relationship between maxillary sinus and adjacent dental region, determining primary site cysts in these regions can be a diagnostic dilemma. In this article, two cases with similar radiological findings are presented. These had lesions involving alveolar process; were surrounded egg-shaped, linear opacities. Diagnoses residual radicular cyst one case calcified mucocoele (which is very rare) other predicted help confirmed surgically histopathologically.

Abstract This study aimed to investigate the potential of inflammatory markers, including platelet‐to‐lymphocyte ratio (PLR), neutrophil‐to‐lymphocyte (NLR), lymphocyte‐to‐monocyte (LMR), and C‐reactive protein‐to‐lymphocyte (CLR), in identifying sacroiliitis. Present retrospective was conducted at Abant Izzet Baysal University Hospital, patients diagnosed with sacroiliitis between August 2020 March 2023. Control subjects normal sacroiliac joints were also included. Sacroiliitis further...
