Introduction and hypothesis: The aim of this study was to cross-culturally adapt and validate the Serbian version of the Australian pelvic floor questionnaire.; Methods: The Australian pelvic floor questionnaire was translated according to the standard method of back-translation. Women who presented with pelvic floor disorders completed the Serbian version of the Australian pelvic floor questionnaire. Women were subjected to clinical and gynecological assessment including physical examination, cough stress test, pelvic prolapse anatomical assessment using the Pelvic Organ Prolapse Quantification system, and post-void residual volume. Reliability and divergent validity was performed on 76 patients with significant pelvic floor dysfunction and 23 women without pelvic floor dysfunction. Patients repeated the questionnaire after 4 weeks.; Results: High reliability was observed in all four dimensions (Cronbach’s alpha coefficients were above 0.8 for each dimension: bladder 0.846, bowel 0.822, prolapse 0.842, and sexual function 0.823). Test-retest analyses revealed high reproducibility (intraclass correlation coefficients were above 0.9). Prolapse symptom score correlated significantly with pelvic organ quantification and bladder score correlated significantly with the results of the cough stress test (convergent validity). Scores distinguished between patients with pelvic floor disorders and controls (high discriminant validity).; Conclusions: The Serbian version of the Australian pelvic floor questionnaire is a reliable and valid instrument for assessment of quality of life in women with pelvic floor disorders. © 2014, The International Urogynecological Association.

Aim: The aims of this study were to evaluate the health-related quality of life (HRQOL) and make the treatment decision less difficult. Methods: Between 2007 and 2009 radical retropubic prostatectomy (RRP) was performed in 96 patients and permanent prostate brachytherapy (PPB) in 88 patients at our hospital. The general and disease-specific HRQOL was measured using two instruments, the Medical Outcome Study 8-Item Short-Form Health Survey (SF-8) and the expanded prostate index composite (EPIC). Results: Comparing RRP and PPB, there were significant differences in all scores except for general health in the 1st month after treatment which had the same score in both groups. The baseline quality of life scores in physical function (p < 0.05), physical role (p < 0.01), social functioning (p < 0.01), emotional role (p < 0.01) and mental health (p < 0.01) showed significant differences between the group and were better in the PPB group than in the RRP group. The physical component summary score in the PPB group was better than in the RRP group in the 1st month (p < 0.01) but recovered up to 3 months in the RRP group. The urinary bother and irritative/obstructive scores in the 1st month were worse from baseline in both groups (p < 0.05) and remained significantly worse up to 6 months in the PPB group than in the RRP group where these scores recovered within3 months. The urinary incontinence score in the RRP group was still worse than in the PPB group up to 12 months (p < 0.01). Bowel function and bother were significantly better in the RRP group at 3 (p < 0.05) and 6 months (p < 0.01) than in the PPB group where bowel function at 12 months was worse than at baseline and in the RRP group. Sexual function (p < 0.01) and sexual bother were better in the PPB group and did not change until 12 months. Conclusion: The difference in disease-specific quality of life has become clearer using EPIC. As with other published studies, our results provide important information that will therefore be useful for selecting the optimal treatments for localized prostate cancer. Copyright © 2010 S.

Introduction/Aim. Glycosaminoglycans (GAG) are one of the main constituents of the connective tissue and cellular membrane. Their presence has been evidenced in mucosa and muscular tissue of the urinary bladder of both healthy individuals and those affected by carcinoma. This suggest their potential role in the onset of bladder carcinoma and follow-up of those patients. The aim of the study was to determine GAG levels in tumor tissue and the surrounding bladder mucosa in patients with bladder tumor, as well as in the bladder mucosa in patients with bladder carcinoma, and to compare the results according to the grade and stage of tumor and relapse. Methods. Tissue samples were taken in 61 patients (48 males and 13 females), mean age 61.5 years, range 40-92 years, obtained by transurethral resection (TUR) of bladder tumor, and 8 healthy persons. Determination of a total GAG content in the tissue samples was done by the Whiteman's method and then compared regarding the tumor grade and stage. Results. Tumor grade and stage directly correlated with the levels of GAG. The GAG levels were significantly higher in tumor samples as compared to healthy mucosa. Conclusion. Higher GAG levels were recorded in all the patients with bladder tumors comparing to smples obtained from healthy individuals. GAG levels do not predict tumor relapse.

Balkan endemic nephropathy (BEN) is interesting renal disease, because of its unique clinical, epidemiological and morphological characteristics: intensive interstitial fibrosis and tubular atrophy without any inflammation. In the present paper we evaluate the incidence of BEN from the morphological point of view for the last decade. Therefore we analyzed material obtained from autopsies, kidney biopsies and nephrectomy due to upper urothelial cancer (UUC) from the patients which were divided into two groups: those with permanent residence in BEN areas and those from nonendemic areas. At the Institute of Pathology, University of Belgrade for the last 15 years we had only 1 autopsy due to BEN out of 6,825. More than 30 years ago there were over 50 autopsy cases of BEN at the same institute. For the last decade we had only 2 kidney biopsies suspected for BEN out of 2,182, but morphologically not confirmed as BEN. However, previously we had over 40 kidney biopsies diagnosed as early or late stage of BEN. At the Clinical Center of Serbia 180 nephrectomies were performed due to UUC. The incidence of UUC for the last five years in BEN regions has significantly decreased, whereas at the same time in non-BEN regions it has remained on the same level. There was no morphological difference of the renal tissue adjacent to tumor between patients from BEN and non-BEN regions. According to our study based on routine pathological work, we could clearly conclude that BEN today is more clinical and epidemiological than a morphological entity. © 2012 Dustri-Verlag Dr. K.

Introduction Primary kidney sarcoma, especially synovial sarcoma (SS), is a very rare neoplasm. Pre-operative signs and symptoms are very similar to renal cell carcinoma, therefore, the proper diagnosis is very difficult and usually made after nephrectomy. This is a case report of primary renal SS. Case Outline A 38-year-old man presented with a history of fever and hematuria, and right flank pain 3 weeks ago. Abdominal computerized tomography revealed a heterogeneous well-marginated soft tissue mass arising in the lower part of the right kidney. Right nephrectomy was performed. A cystic tumor of 120x85 mm in size with soft solid growth, and with the extensive areas of hemorrhage and necrosis was seen on gross examination. Histopathology revealed a neoplasm composed of solid monomorphic sheets of spindle cells. Immunohistochemistry showed tumor cells strongly positive for BCL2, CD99, CD56 and vimentin, and focally positive for epithelial membrane antigen (EMA). The histological diagnosis of primary renal SS was based on morphology and immunohistochemistry. FISH analysis and RT-PCR was carried out on formalin-fixed paraffin-embedded tissue sections. The molecular analysis demonstrated translocation of SYT gene on chromosome 18 and SSX2 gene on chromosome X. The findings were consistent with diagnosis of SS. Conclusion Our case shows that histopathological diagnosis of primary kidney SS, although difficult, is possible to be made on the basis of morphological and immunohistochemical analysis. However, this diagnosis should be corroborated by molecular techniques confirming SYT-SSX translocation on chromosome 18 and chromosome X. Here we present visceral monophasic SS with aggressive clinical course and poor outcome.

Members of the glutathione S-transferase (GST) superfamily exhibit polymorphic expression. GSTs are investigated as biomarkers of risk for various cancers, including renal cell carcinoma (RCC). The aim of this study was to test the association between GSTM1 and GSTT1 polymorphism and susceptibility to RCC, independently or in conjunction with known risk factors. Genomic DNA was isolated from 182 controls and 76 patients with RCC. GSTM1 and GSTT1 genotypes were determined by multiplex PCR. Data obtained were analyzed with respect to RCC risk factors including smoking and occupational exposure. The frequency of GSTM1-null genotype was higher in patients with RCC (60.5%) compared to controls (47.2%). GSTT1-null genotype was found in 28.6% controls and 27.6% of cases. GSTM1-null individuals exhibit 1.9-fold increased risk of RCC (95% CI: 1.06-3.33). The presence of GSTT1 active genotype was associated with increased risk of RCC in occupationally exposed subjects when unexposed GSTT1-null subjects were used as a comparison group (OR: 2.48; 95% CI: 1.05-5.86). No association was found between the inactive form of GSTM1 and GSTT1 and smoking in RCC patients. In a Serbian cohort of patients, the presence of a GSTM1 active genotype is protective against RCC, whereas a GSTT1 active genotype increases RCC risk in occupationally exposed subjects.

Introduction Y chromosome microdeletions are the second most frequent genetic cause of male infertility after Klinefelter's syndrome. Objective The aim of the study was to determine the frequency of Y chromosome microdeletions in a group of infertile men with an idiophatic cause of infertility, candidates for microfertilization (Intra-cytoplasmic Sperm Injection - ICSI) in Serbia and to correlate genotype-phenotype in patients with Y chromosome microdeletions. Method One hundred and sixty patients with low sperm count (less than 5x106 spermatozoa/ml) were enrolled in the study. Forty patients were excluded from the study: ten because they were diagnosed with cytogenetic abnormality and thirty patients were diagnosed with other known causes of infertility. The control group consisted of 150 men who fathered at least one child in the last two years. Genomic DNA was extracted from peripheral blood samples and two multiplex polymerase chain reactions (PCR) analyses were performed using specific primers to confirm the presence or absence of Y chromosome microdeletions. Results Microdeletions were detected in 12 of 120 (10%) cases, while no deletions were detected in the control group. Of total number of 12 deletions, nine were detected in AZFc region (75%), one in AZFa (8%), and two in AZFbc (17%). Conclusion Testing for Y chromosome microdeletions should be considered as an important element in diagnosis and genetic counselling of infertile couples in Serbia. Decisions regarding the assisted reproduction should be made based on the detailed clinical, endocrinological and cytogenetic examinations, spermogram, presence or absence and type of AZF microdeletions and CFTR gene mutations.
