The interaction between multiple myeloma (MM) cells and the bone marrow stroma constitutes the basis of myeloma pathogenesis and has led the way for the corresponding therapeutic strategies. The aim of this study is to evaluate tumor-associated macrophages (TAMs) which is an important element of bone marrow stroma and its prognostic relevance in newly diagnosed MM patients. We also wanted to determine the association between TAMs and microvessel density (MVD). Sixty-eight patients, who were diagnosed with MM at the Department of Hematology, Gazi University Hospital, between January 2000 and January 2011, were reviewed retrospectively. Tumor-associated macrophages were evaluated by staining with anti-CD68 and anti-CD163 monoclonal antibodies, and MVD was evaluated by factor VIII staining. Median age was 60 (range, 40-84) years with 36 males and 32 females. The number of both CD 68+ and CD 163+ cells had a negative impact on OS at 6 years (p = 0.013 vs. 0.036; p = 0.015 vs. 0.039) in univariate and multivariate analysis in which age, sex, ISS, the induction treatment, and response to induction treatment are included as variables. High-grade MVD was found to be associated with increased CD163+ cell count. In conclusion, TAMs seems to be a promising prognostic histopathological marker in newly diagnosed MM patients.

Objectives The aims of this study are to evaluate expressions of Ki67, RacGAP1 (MgcRacGAP) and topoisomerase 2 alpha (TOP2a), the markers related with cell proliferation that have been proposed to affect the prognosis in the literature and correlate the results with clinicopathological parameters of breast cancer patients. Methods Ki67, RacGAP1, and TOP2a antibodies were applied immunohistochemically to the tissue micrarray blocks of 457 female breast cancer patients. The results were correlated with clinical, prognostic, histopathological features, and other immunohistochemical findings (estrogen receptor [ER], progesterone receptor [PR], HER2, cytokeratin [CK]5/6, CK14, epidermal growth factor receptor [EGFR] and vimentin), statistically. Results Ki67 expression demonstrated direct correlation with TOP2a expression, mitotic count, tumor grade, geographic necrosis, basal-like phenotype. RacGAP1 expression was directly correlated with TOP2a expression, nipple invasion, and number of metastatic lymph nodes, and it was inversely correlated with PR expression. TOP2a expression was directly correlated with vimentin and Ki67 expressions, mitotic count, tumor grade, and geographic necrosis, and nipple invasion, and negatively correlated with ER and PR expressions. Higher TOP2a and Ki67 expressions were correlated with shorter overall survival. Higher TOP2a expression and RacGAP1 positivity were directly correlated with shorter disease-free survival. Conclusion This study showed that the overexpressions of Ki67, RacGAP1, and TOP2a affect the prognosis adversely, thus to develop target therapies against RacGAP1 and TOP2a as well as using Ki67 as a part of routine pathology practice might be beneficial in breast cancer therapy and prediction of prognosis.

DOG1 positivity was detected in most of GISTs and all in CD117-negative cases as a result underlining its diagnostic utility. Additionally, DOG1 overexpression was related with adverse prognosis. Thus, we suggest that immunostaining index of DOG1 should routinely be used while diagnosing GIST, and DOG1 might be considered as a potential prognostic tool and a target for novel therapies.

Purpose: To evaluate the effects of different contact lens (CL) replacement schedules and different CL materials on the ocular surface and tear function. Methods: Daily disposable hydrogel CLs were given to group 1 (n = 22), daily disposable silicone hydrogel CLs were given to group 2 (n = 25), and reusable silicone hydrogel CLs were given to group 3 (n = 24). Tear function tests and inflammatory cytokine [interleukin (IL)-6, IL-8, IL-17A, and matrix metalloproteinase (MMP)-9] levels were evaluated before and at 1 and 3 months after CL usage. Impression cytology was evaluated before and at 3 months after CL usage. Results: At the first and third months of CL usage, a statistically significant difference was determined between the groups in the levels of IL-6, IL-8, and IL-17A in tears, with the lowest levels in group 1 and the highest levels in group 3 (all P < 0.05). At the third month of CL usage, the levels of these cytokines (in picograms/milliliter) were 6.06 ± 0.83, 78.18 ± 12.42, 61.69 ± 13.95, and 37.71 ± 5.95 in group 1 and 8.04 ± 0.89, 107.34 ± 14.40, 68.63 ± 13.72, and 46.26 ± 6.50 in group 3, respectively. A statistically significant decrease was determined over time in the Schirmer test in group 1, in only the tear breakup time in group 2, and in the tear breakup time and Schirmer test in group 3 (all P < 0.05). A statistically significant increase was determined over time in the levels of IL-6, IL-8, IL-17A, and MMP-9 in all groups. In the third month, a significant progression was observed in the Nelson grade (P < 0.05) in all groups. Conclusions: The wear of daily disposable CLs can be considered to cause less damage to the ocular surface and less increase in proinflammatory cytokine levels.

IGFR1 with heterotetrameric receptor via IGF1, IGF2, insulin, and probably androgen, contribute to the remodeling and development of CM as well as the testis descent. In the current study, the presence of the IGFR1 in the CM was shown. Additionally, the IGFR1 density of the CM was lower in the UT cases than in the CG cases. Further evaluation of IGFR1 and other etiological factors can elucidate how they interact.

Background Cervical cancer screening algorithms are increasingly focused on Human Papillomavirus (HPV)‐based screening while the accuracy of using abnormal cytological findings to detect dysplastic lesions still remains important. This retrospective study correlated the results of conventional cervical cytology, colposcopy guided biopsy, and cold knife conization (CKC) procedures performed in a tertiary center. Materials and Methods Data from 9399 patients who underwent screening with conventional cervical cytology between 2010 and 2019 was obtained from the hospital registry. Abnormal cervical cytology and high‐risk HPV DNA genotypes were recorded and their colposcopic and CKC pathology was determined. Results Two hundred and ninety two patients underwent colposcopy for abnormal cervical cytology and/or high‐risk HPV positivity. One hundred and twenty three patients were positive for High‐risk HPV. Abnormal cervical cytology was detected in 216 patients. The most common cytological anomaly was atypical squamous cells of undetermined significance (ASCUS) found in 9399 patients (1.39%). It was determined that conventional cytology had a sensitivity of 70.8% and a specificity of 62.2% for the detection of low‐grade lesions, while it had a sensitivity of 72.4% and a specificity of 86.0% for the detection of high‐grade lesions. CKC was applied to 68 patients who were diagnosed with high‐grade squamous intraepithelial lesions (HSIL) as a result of the colposcopy. As a result of CKC, a high‐grade lesion was detected in 73.5% of these patients. Conclusion Conventional cervical cytology and colposcopy exhibited higher accuracy as the severity of lesions increased. Detection of HPV may prevent unnecessary surgical procedures, especially with ASCUS.

Gürel G, Şahin S, Çölgeçen E. A case of aquagenic syringeal acrokeratoderma with involvement of periungual area of the hand. Turk J Pediatr 2018; 60: 762-764.Aquagenic syringeal acrokeratoderma (ASA) is a rare form of palmoplantar keratoderma occurring after short-term contact with water. Although ASA usually involves the palmar region, there are also several cases with the involvement of dorsum of hand and sole of the feet. We described 15-year old girl who had white keratodermic plaques observed on the flexor side of distal phalanxes especially the periungual area after a 10 min contact with water. Our patient represents a rare case of ASA with the involvement of periungual region of the fingers.
