Background We aimed in our study to research the role of new cytokines such as IL-35, IL-22, and IL-17 that may form a target for novel treatment approaches. Methods IL-10, IL-17, TGF-β, IFN-γ, IL-22, and IL-35 serum levels of allergic rhinitis (AR) patients were measured using ELISA method. Allergic sensitization was demonstrated by the skin prick test. Patients only with olive tree sensitivity were evaluated for seasonal AR (SAR). Patients only with mite sensitivity were included in the study for perennial AR (PAR). AR clinic severity was demonstrated by the nasal symptom scores (NSS). Results In total, 65 AR patients (patient group), having 31 PAR and 34 SAR patients, and 31 healthy individuals (control group) participated in the study. Cytokine levels between the patient group and the control group were compared; IL-17 (p = 0.038), IL-22 (p = 0.001), and TGF-β (p = 0.031) were detected as high in the patient group, and IFN-γ (p < 0.001) was detected as low in the patient group. When correlation analysis was made between age, gender, prick test result, NSS, AR duration, and cytokine levels in the patient group, a negative correlation was detected only between IFN-γ (p = 0.032/r = −0.266) level and NSS. Conclusions Accompanied by the literature information, these results made us think that T cell subgroups and cytokines have an important role in AR immunopathogenesis. It is thought that future studies to be conducted relating to this subject will form new targets in treatment.

Objectives:The present study evaluates the relationship between the expression levels of hormone receptors (HRs), Ki-67, p53 and serum cancer antigen 125 (CA125) levels in endometrial cancer and clinicopathological risk factors, and determines their prognostic values. Material and methods:This retrospective study included 49 patients with endometrial cancer whose estrogen receptor (ER) and progesterone receptor (PR) Ki-67 and p53 expression levels were determined through immunohistochemical methods, and whose preoperative serum CA125 levels were measured. These factors relationship with various clinicopathological factors, progression-free survival (PFS) and overall survival (OS) was investigated. Results:The study included 49 patients with EC with a mean age of 61 ± 10 years. The rate of HR positivity was significantly higher in the endometrioid histology group than in the non-endometroid histology group (p = 0.026). A high level of Ki-67 expression was found to be associated with a non-endometroid histology (p = 0.016), and a high tumor grade (p < 0.001) and a high p53 expression were found to be associated with advanced disease stage (p = 0.026). A positive correlation was found between p53 and Ki-67, a negative correlation was found between p53 and Ki-67 and the presence of HR. Significant relationship was not found between HR status, p53, Ki-67, CA125 and either other clinicopathological risk factors or survival. Conclusions:While HR positivity indicates favorable clinicopathological prognostic factors, high Ki-67 and high p53 expression indicate unfavorable ones. However, no direct effect of these factors on prognosis was found in this study.

AT-rich interactive domain 1A (ARID1A) is a tumor suppressor gene involved in chromatin remodeling which encodes ARID1A (BAF250a) protein. Recent studies have shown the loss of ARID1A expression in several types of tumors. This retrospective study was designed to evaluate the differences in tissue expressions of ARID1A in a spectrum of cervical neoplasms. Cervical intraepithelial neoplasms, invasive squamous or adenosquamous carcinomas were identified in 100 patients recently diagnosed as cervical neoplasms based on pathology databases. In this series, there were 29 low- and 29 high-grade cervical intraepithelial neoplasms, 27 squamous cell carcinomas, and 15 adenosquamous carcinomas. Mean age of the patients was 47.8 ± 13 years (20-80 years). It was determined that the expression of ARID1A was statistically significantly down-regulated in adenosquamous carcinomas when compared with non-invasive or invasive squamous cell carcinomas (p = 0.015). Lower levels of the ARID1A expression were detected in cases with adenosquamous carcinomas (60%), low- or high-grade squamous intraepithelial lesion (SIL) (31%), and squamous cell carcinomas (18.5%). Our findings have demonstrated the presence of a correlation between ARID1A expression and adenomatous differentiation of uterine squamous cell carcinomas. Therefore, ARID1A gene may suggestively have a role in the pathogenesis of cervical adenosquamous carcinomas.

Accumulating evidence has demonstrated upregulation of neutrophil gelatinase-associated lipocalin (NGAL) and kidney injury molecule-1 (KIM-1) in multiple malignancies which play a critical role in tumor progression. However, up to now little is known about the role played by NGAL in human uterine cervical carcinomas. In this retrospective study we aimed to evaluate the role of tissue expressions of NGAL and KIM-1 in a spectrum of uterine invasive and noninvasive cervical neoplasms. Methods: Immunohistochemical NGAL and KIM-1 expressions were investigated in a total of 107 formalin-fixed, para fin-embedded uterine cervical tumor specimens and their association with di ferent clinicopathologic parameters was evaluated. Results: In this series, cases with 30 low-and 29 high-grade cervical squamous intraepithelial lesion (SIL), 27 squamous cell carcinoma (SCC), 15 adenosquamous carcinoma (ASC) and 6 adenocarcinoma (ACs) were detected. Positive NGAL expression was detected in only in lammatory cells of cases, whereas KIM-1 expression was detected in tumor cells. Statistically it was determined that the positivity rate of strong NGAL and KIM-1 expression was prominently higher in invasive carcinomas when compared with non-invasive squamous cell neoplasms (P < 0.01). KIM-1 expressions were not detected in any of the few cases with adenocarcinoma. Conclusion: Our findings have showed the presence of a correlation between membranous and cytoplasmic expressions of NGAL and KIM-1 and the invasive characteristics of uterine cervical neoplasms. As a result, expressions of NGAL and KIM-1 may be important in foreseeing the invasion and tumor progression.

Our findings were demonstrated that perivascular Cav-1 expression was seen to be a marker for malignancy of uterine SMTs. Similarly, we found to link of ARID-1A expression and the aggressiveness of SMTs. Therefore, it may be suggested that Cav-1 and ARID-1A may act as predictive biomarkers in uterine SMTs.

Malakoplakia is a rarely seen inflammatory condition that is considered to develop secondary to a chronic Escherichia coli infection. Although malakoplakia usually affects the genitourinary tract, it may also be observed in the colon, stomach, lungs, liver, bones, uterus, and skin. Malakoplakia of the genitourinary system usually involves the bladder, whereas it may also affect the prostate along with the bladder. Malakoplakia of the prostate is very rare, and it may be clinically mistaken for prostatic malignancies. Definitive diagnosis is only possible through histopathological examination. This study elaborates on two patients who presented to our hospital in 2013 with high PSA levels. The primary clinical consideration was prostate carcinoma. However, these two cases were diagnosed as malakoplakia based on the results of histopathological analysis of the transrectal prostate biopsy specimen.
