    Objective: Mammography may have some limitations in the diagnosis and screening of breast cancer for women who have previously undergone breast reduction surgery. This study aimed to investigate how the structural defects in the breast tissue formed by postoperative changes are reflected on mammography. Material and Methods: The records of patients who had previously undergone breast reduction surgery and who were requested to undergo mammography for breast cancer screening by the general surgery clinic were retrospectively studied. The patients' ages, surgical procedures, postoperative follow-up periods, amount of removed material, and histopathological and mammographic results were studied. The patients were classified into 3 groups: those older than 40 years who underwent reduction mammoplasty targeting predominantly the glandular tissue (group 1), those younger than 40 years who underwent reduction mammoplasty targeting predominantly the fat tissue (group 2), and those older than 40 years who were diagnosed with breast hypertrophy and were not operated (group 3). Results: The mean follow-up period of the patients was 6 (2-10) years. The mean value of resected tissue was 1120 g (680-2070) in group 1 and 1220 g (720-1980) in group 2. The mean age at the time of surgery was 45 (40-70) years for group 1 and 35 (24-40) years for group 2. All patients in group 1 were classified in Breast Imaging-Reporting and Data System (BI-RADS) category 1-2; 28 patients in group 2 were classified in BI-RADS 1-2, 4 were classified in BI-RADS 3, and 8 were classified in BI-RADS 0. In group 3, 35 patients were classified in BI-RADS 1-2, 4 were classified in BI-RADS 3, and 1 was classified in BI-RADS 0. Conclusion: We believe that breast reduction surgery targeting predominantly the glandular tissue in patients older than 40 years increases mammographic sensitivity.

    Niemann-pick type b disease diagnosed in the adulthood
    (2018) Demircioğlu, Sinan; Korkmaz, Celalettin; Çizmecioğlu, Hilal Akay; Poyraz, Necdet
    Niemann-Pick disease (NPD) type B is an autosomal recessive liposomal storage disorder. NPD type B can present later inlife with predominantly visceral symptoms, and has a more favorable prognosis. The natural history of NPD -B is one ofprogressive hypersplenism and gradual deterioration of pulmonary function. In this paper, we presented NPD type Bpatient who were diagnosed at 41 years old while being followed for years with the diagnosis of interstitial lung disease.

    Prognostic value of preoperative neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios, and multiphasic renal tomography findings in histological subtypes of renal cell carcinoma
    (BMC, 2014) Keskin, Suat; Keskin, Zeynep; Taskapu, Hakan Hakki; Kalkan, Havva; Kaynar, Mehmet; Poyraz, Necdet; Toy, Hatice
    Background: To determine the relationship between renal cell carcinoma subtypes and the associated mortality and biochemical parameters. An additional aim was to analyze multiphasic multidetector computed tomography findings. Methods: This study is a hospital-based retrospective investigation, using 211 patients with a diagnosis of renal cell carcinoma upon computed tomography examination. The histological subtypes included clear cell in 119 patients, chromophobe cell in 30 patients, papillary cell in 25 patients, mixed cell in 32 patients, and sarcomatoid cell in 4 patients. Results: The mean age of the patients participating in this study was 61.18 +/- 11.81 years, and the mortality rate was 10.4% (n = 22) through the 2-year follow-up. The ratios of both the neutrophil-to-lymphocyte upon admission to the hospital and platelet-to-lymphocyte of the non-surviving group were significantly higher than those of the surviving group (p < 0.05). When the analysis of the 2-year survival of the patients was examined according to the median platelet-to-lymphocyte ratio values, the Kaplan-Meier survival curves were significantly different between the surviving and non-surviving groups (p = 0.01). In two-way analysis of variance test, statistically significant results which were influenced by mortality (p = 0.028) and were found between renal cell carcinoma subtypes in the computed tomography density of corticomedullary phase (p = 0.001). Conclusions: The neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio may represent widely available biomarkers in renal cell carcinoma, and the logistic regression model indicated that neutrophil-to-lymphocyte ratio was a significant predictor for mortality. According to the median platelet-to-lymphocyte ratio values, the Kaplan-Meier survival curves were significantly different between the surviving and non-surviving groups.
