Purpose: We aimed to study the inflammatory parameters of complete blood count in breast cancer cases. Materials and Methods: This retrospective covered 178 patients 107 age body mass index matched healthy women. Complete parameters, neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte (PLR) MPV/platelet were analyzed. Results: The leukocyte, neutrophil higher patient group (p values 0.001, 0.0001 0.0001, respectively) while haemoglobin hematocrit control (p=0.0001 for both). Logistic...

Amyloidosis results from extracellular deposition of a fibrillary protein in various organs, and renal biopsy is the best, but complicated tool for diagnosis. Therefore, alternative sites have been proposed with varying degrees sensitivity. We aimed to find most appropriate site patients chronic kidney disease (CKD) whom contraindicated or unavailable. 42 (29 male; mean age 46 ± 16 y) CKD amyloidosis was suspected as underlying etiology on clinical grounds, not available (Group I), 36 (25 40...
