Abstract
INTRODUCTION We aimed to evaluate the status of spermatogenesis detected by histological examination of non-tumoral testicular tissues in tumor bearing testis and its association with advanced stage disease. PATIENTS AND METHODS We retrospectively reviewed patients with testicular germ cell tumors (TGCTs) that undergone radical orchiectomy. All non-tumoral areas of the orchiectomy specimens were examined for the status of spermatogenesis. Patients were divided into two groups as localized (stage I) and metastatic (stage II-III) disease and analyzed separately for seminomatous (SGCT) and nonseminomatous germ cell tumors (NSGCT). RESULTS Four hundred fifty-four patients were included in our final analysis. Of those, 195 patients had SGCT, and 259 patients had NSGCT. Three hundred and six patients had localized disease at the time of diagnosis. Median (Q1-Q3) age was 31 (26 - 38) years and 102 (22.5%) patients had normal spermatogenesis, 177 (39.0%) patients had hypospermatogenesis and 175 (38.5%) patients had no mature spermatozoa. On multivariate logistic regression analysis, embryonal carcinoma >50% (1.944, 95 %CI 1.054-3.585, P = .033) and spermatogenesis status (2.796 95% CI 1.251-6.250, P = .012 for hypospermatogenesis, and 3.907, 95% CI 1.692-9.021, P = .001 for absence of mature spermatozoa) were independently associated with metastatic NSGCT. However, there was not any variables significantly associated with metastatic SGCT on multivariate logistic regression analysis. CONCLUSION Our study demonstrated that only 22.5% of patients with TGCTs had normal spermatogenesis in tumor bearing testis. Impaired spermatogenesis (hypospermatogenesis or no mature spermatozoa) and predominant embryonal carcinoma are associated with advanced stage NSGCT.

Abstract
Xanthomatous meningioma is an extremely rare subtype of metaplastic meningiomas with few cases reported in the literature. Histopathologically, it is composed of oval-shaped cells that have central nuclei and cytoplasm with lipid-filled vacuoles, resembling macrophages. Here, the authors present a case of xanthomatous meningioma and discuss the hypotheses related to its origin and the differential diagnosis. A 40-year-old woman presented with an increased headache complaint over the past month. A computed tomography scan revealed a heterogeneous mass on the right parietal lobe, following which a right craniotomy was done. Microscopic examination showed neoplastic meningothelial cells with whorl formation and areas of xanthomatous changes. Both meningothelial and xanthomatous cells were positive with vimentin, progesterone, and epithelial membrane antigen. CD68 and lysozyme were expressed only in the xanthomatous component, and there was no expression with periodic acid-Schiff (PAS) stain and PAS–diastase. As the diagnostic criteria of atypical meningioma were not observed, a diagnosis of xanthomatous meningioma, WHO grade I, was made. Owing to the characteristic xanthomatous changes, its differential diagnosis includes grade II clear cell meningioma, Rosai–Dorfman disease, and hemangioblastoma. To avoid misidentifying these cells as macrophages, a high degree of awareness of this unique subtype of meningioma is required.

Abstract
Splenic involvement is rarely reported in patients with ANCA-associated vasculitides (AAVs), particularly in those with granulomatosis with polyangiitis (GPA) and is in fact considered to be underestimated. We aimed to investigate the frequency of splenic lesions-mainly infarction-and related factors in patients with AAVs. Patients with AAV whose abdominal or thoracic computed tomographies (CTs) were performed at or after diagnosis were included in the study. CT images were examined for splenic lesions. Overall, 69 patients (median age at diagnosis 54 [IQR 24] years; 55% with GPA, 29% with microscopic polyangiitis, and 16% with renal-limited disease) were included in the analysis. Splenic pathologies were detected in 19 (28%) patients; 12/19 (63%) splenomegaly and 7/19 (37%) splenic infarction. All patients with splenic infarction exhibited GPA with PR3-ANCA-positive serology. Three of these seven patients had autosplenectomy. Patients with splenic infarction were younger at diagnosis (p = 0.018) with also significantly higher ear-nose-throat (ENT) (%100 vs 37; p = 0.002) and eye involvement (%50 vs %12; p = 0.044) than patients without splenic infarction. Splenic pathologies are not rare in AAVs. Furthermore, infarction can help separate GPA from MPA. In young patients with GPA, particularly those with ENT and eye involvements, physicians should consider splenic infarction.Key Points• Splenic infarction is more common than previously thought in ANCA-associated vasculitides, particularly in granulomatosis with polyangiitis.• Detecting splenic infarction can help differentiate granulomatosis with polyangiitis from other subgroups.

Abstract
Giant cell angiofibroma (GCA) is a recently reported rare soft-tissue tumor that can develop in various sites including orbit. Orbital GCAs were mainly located in the eyelid or extraconal regions such as lacrimal gland and conjunctiva. We report an atypical case of a GCA arising in the intraconal area of the orbit in a 65-year-old male patient. The tumor was excised in total by lateral orbitotomy. Histological and immunohistochemical features were consistent with the diagnosis of GCA. No recurrence was observed during the follow-up of over 2 years. GCA is a rare tumor that should be considered in the differential diagnosis of intraconal orbital tumors. Complete surgical removal is the current optimal treatment option.

Abstract
INTRODUCTION Hydatid disease is an endemic parasitic infection caused by Echinococcus granulosus mostly seen in the Mediterranean countries. The most affected organ is the liver, however hydatidosis can be found anywhere in the human body. METHODS The records of patients who were diagnosed with hydatid disease in our hospital from December 2005 to February 2016 were analyzed retrospectively. The cases were evaluated and recorded depending on their gender, age and the localization of the cysts. RESULTS A total of 329 patients diagnosed over a 10-year period were included in our study. There were 202 females (61.4%) and 127 males (38.6%). The hydatid cysts were located in the liver in 257 (78.1%) patients and in unusual locations in 72 (21.9%) patients. The most common unusual site for hydatid cysts was the spleen followed by bones, central nervous system, soft tissue, the kidney and the gall bladder. Amongst these 72 patients who had hydatid cysts in unusual locations; 33 patients had concomitant liver hydatidosis, whereas 39 patients had primary involvement of unusual sites. Two patients with malignancies also had hydatid cysts in different locations. CONCLUSION Hydatid disease affects many organs in the body and therefore it can pose a major diagnostic dilemma and it may mimic other entities. In endemic areas, a differential diagnosis of hydatid disease should be considered for cystic masses in any anatomical location.

Abstract
Introduction. In this study, we investigate the toxic effects of tacrolimus (FK506) on the cardiovascular system at the histopathological level in a rat model and whether these effects can be reversed by the blockade of the renin-angiotensin system (RAS) by either an angiotensin-converting enzyme inhibitor (ACE-inhibitors) or an angiotensin receptor antagonist (ARB). Methods and results. Thirty-one Wistar rats were divided into four groups. FK506 group was treated with FK506 intraperitoneally (i.p.), FK506+ACE-inhibitors and FK506+ARB groups were treated with either quinapril or valsartan orally in addition to FK506. Control group was treated with saline i.p. Histological and immunohistochemical staining of cardiovascular tissue in the FK506 group showed increased vacuolar degeneration (11.2 vs. 5.8, p=0.008), arterial hyalinosis (10.7 vs. 6. G 3, p=0.036), transforming growth factor-beta (TGF-β) (12.2 vs. 4.8, p=0.001) and vascular endothelial growth factor expression (VEGF) (10.7 vs. 6.3, p=0.036), elastic van Gieson (11.5 vs. 5.5, p=0.004), and periodic acid O Schiff stain scores (12.5 vs. 4.5, p<0.001) compared to the control group. Immunohistochemical scores showed that expression of TGF-β is up-regulated, and bone morphogenic protein (BMP-7) is down-regulated with FK506 toxicity. Adding RAS blockade with either an ACE-inhibitor or an ARB could reverse FK506 induced changes. Both FK506+ACE-inhibitors and FK506+ARB groups demonstrated decrease in arterial hyalinosis (22.1 vs. 14.4 (FK506+ACE-inhibitor) and 13.6 (FK506+ARB), p=0.09) and vacuolar degeneration (23.1 vs. 16.1 (FK506+ACE-inhibitor) and 12.4 (FK506+ARB), p=0.006) scores compared to the FK506 group. Conclusion. Blockade of RAS could reverse the histopathological signs of FK506 induced cardiac toxicity in a rat model.

Abstract
BACKGROUND Breast cancer is the most common cause of deaths of cancer in women. Nowadays, following completion of imaging methods, mainly fine needle aspiration biopsy (FNAB) and core biopsy methods have been used for establishing cytopathological diagnosis although discussions regarding superiority continue. MATERIALS AND METHODS Those with a complaint of "mass in breast" along with those diagnosed to have a mass as a result of routine physical examination among all patients applying to our clinic between 01.01.2009 and 31.12.2011 were retrospectively assessed. Totals of 146 and 64 patients with complete radiological observation who had undergone FNAB and core biopsies, respectively, were evaluated. Postoperative pathological results of patients of both groups receiving surgery were also taken into consideration. All results were compared in terms of false positivity/negativity, sensitivity/specifity, surgery types and distribution of postoperative results with regard to diagnoses along with those of malignant/benign masses with regard to quadrants determined. RESULTS Diagnostic malignancy power of mammographic BIRADS classification was 87.3%. However, the value was 75% in the core biopsy group. Sensitivity and specifity following comparison of FNAB and postoperative pathology results of those receiving surgery were 85.4% and 92.9% while they were 93.5% and 100% in the core biopsy group. Diagnostic malignancy power, calculated by determining AUC in ROC analysis, of FNAB was 89.1% while that of core biopsy was 96.7%. CONCLUSIONS It was shown that core biopsy is superior to FNAB in terms of sensitivity, specificity and accurate histopathological classification. However; quick, cheap and basic diagnosis by means of FNAB should not be ignored. Sensitivity of FNAB is rather high in experienced hands and furthermore it would be expected to be lower than with core biopsy.

Abstract
PURPOSE We aimed to evaluate the effects of hormone receptor, HER2, and epidermal growth factor receptor (EGFR) expression on epithelial ovarian cancer (EOC) prognosis and investigate whether or not phenotypic subtypes might exist. MATERIALS AND METHODS The medical records of 82 patients who were diagnosed with EOC between 2003 and 2012 and treated by platinum-based chemotherapy were retrospectively evaluated. Expression of EGFR, oestrogen (ER), progesterone (PR), and cerbB2 (HER2) receptors were assessed immunohistochemically on paraffin-embedded tissues of these patients. Three phenotypic subtypes were defined according to ER, PR, and HER2 expression and associations of these with EGFR expression, clinicopathologic features, platinum sensitivity, and survival were investigated. RESULTS When we classified EOC patients into three subtypes, 63.4% had hormone receptor positive (HR(+)) (considering breast cancer subtypes, luminal A), 18.3% had triple negative, and 18.3% had HER2(+) disease. EGFR positivity was observed in 37 patients (45.1%) and was significantly more frequent with advanced disease (p=0.013). However, no significant association with other clinicopathologic features and platinum sensitivity was observed. HER2(+) patients had significantly poorer outcomes than HER2(-) counterparts (triple negative and HR positive patients) (p=0.019). Multivariate analysis demonstrated that the strongest risk factor for death was residual disease after primary surgery. CONCLUSIONS Triple negative EOC may not be an aggressive phenotype as in breast cancer. The HER2 positive EOC has more aggressive behaviour compared to triple negative and HR(+) phenotypes. EGFR expression is more frequent in advanced tumours, but is not related with poorer outcome. Additional ovarian cancer molecular subtyping using gene expression analysis may provide more reliable data.

MATERIALS AND METHODS A total of 22 patients diagnosed with a pheochromocytoma between 2000-2010 in Izmir Katip Celebi University Ataturk Training and Research Hospital were included. Diagnostic value of the PASS scoring system, and prognostic correlations of histopathologic parameters and Ki-67 proliferation index were investigated. SPSS for Windows 17.0 software was used for statistical analysis. RESULTS There was no statistically significant correlation between recurrence and clinicopathologic parameters or the PASS score (PASS>4). In addition, there were no statistically significant correlations between PASS score and clinicopathologic parameters, such as diameter (5 cm), weight (>100g), gender (female/male ratio) and age (25-45/45-55/>55). Besides, there were no significant correlation between diameter and clinicopathological parameters and also recurrence. However, there was a statistically significant correlation between Ki-67 proliferation index and capsule invasion (p=0.047). CONCLUSIONS Some but not most of the findings in our study were concordant with the literature. To clarify relationships, investigations with standard scoring systems which are not affected by subjective factors and feature appropriate histopathological criteria should be made on larger study groups.

Abstract
The purpose of our study was to investigate the diagnostic value of expression of IMP3, nucleophosmin, and correlation of these markers with Ki-67 proliferation index in papillary thyroid carcinoma and benign neoplasms of thyroid gland. The aim was also to investigate whether there is a difference between papillary and micropapillary carcinomas with regard to clinicopathologic parameters beside IMP3, nucleophosmin, and Ki-67 proliferation index. It was concluded that IMP3 and nucleophosmin cannot be a routine diagnostic marker for discrimination of papillary carcinomas and benign lesions. IMP3 positive staining was quite scarce in IMP3 positive papillary carcinomas although specifity of IMP3 is 100%. A statistically significant correlation was not detected between nucleophosmin, IMP-3, and Ki-67 proliferation index. A statistically significant correlation was found between tumor size, lymphovascular embolism, and Ki-67 proliferation index. There was also significant correlation between tumor size and lymphovascular embolism.

Abstract
BACKGROUND To investigate the predictive and prognostic effects of clinicopathologic and immunohistochemical (IHC) features in patients with gastrointestinal stromal tumours (GISTs). MATERIALS AND METHODS Fifty-six patients who were diagnosed with GIST between 2002 and 2012 were retrospectively evaluated. Relationships between clinicopathologic/immunohistochemical factors and prognosis were investigated. RESULTS Median overall survival (OS) of the whole study group was 74.9 months (42.8-107.1 months), while it was 95.2 months in resectable and 44.7 months in metastatic patients respectively (p=0.007). Epitheliolid tumor morphology was significantly associated with shortened OS as compared to other histologies (p=0.001). SMA(+) tumours were significantly correlated with low (<10/50HPF) mitotic activity (p=0.034). Moreover, SMA(+) patients tended to survive longer and had significantly longer disease-free survival (DFS) times than SMA (-) patients (37.7 months vs 15.9 months; p=0.002). High Ki-67 level (≥30%) was significantly associated with shorter OS (34 vs 95.2 months; 95%CI; p=0.001). CD34 (-) tumours were significantly associated with low proliferative tumours (Ki-67<%10) (p=0.026). Median PFS (progression-free survival) of the patients who received imatinib was 36 months (27.7-44.2 months). CD34 (-) patients had significantly longer PFS times than that of negative tumours; (50.8 vs 29.8 months; p=0.045). S100 and desmin expression did not play any role in predicting the prognosis of GISTs. Multivariate analysis demonstrated that ≥10/50HPF mitotic activity/HPF was the only independent factor for risk of death in GIST patients. CONCLUSIONS Despite the negative prognostic and predictive effect of high Ki-67 and CD34 expression, mitotic activity remains the strongest prognostic factor in GIST patients. SMA positivity seems to affect GIST prognosis positively. However, large-scale, multicenter studies are required to provide supportive data for these findings.

Abstract
OBJECTIVE The goal of this study was to investigate the between cluster of differentiation 109 (CD109) expression and tumor diameter, invasion depth, tumor grade, presence of lymph-node metastasis, and overall survival in patients with vulvar squamous cell carcinoma, which is the most common type of vulvar cancer. METHOD Twenty-six patients who underwent an operation for vulvar cancer between 1999 and 2009 in our clinic were included in this study. Immunohistochemical staining was performed on formalin-fixed and paraffin-embedded tissue. RESULT Tumor diameter was not found to be significantly associated with CD109 expression, intensity of cytoplasmic staining, or combined score (P = 0.325, P = 0.169, P = 0.352, respectively). Invasion depth and combined score were also not significantly correlated with CD109 expression (P = 0.324 and P = 0.174 respectively). There was a negative correlation between invasion depth and the intensity of cytoplasmic staining (P = 0.042). There was no significant correlation between tumor stage and CD109 expression, the intensity of cytoplasmic staining, and the combined score (P = 0.574, P = 0.389, P = 0.605, respectively). A significant positive correlation was observed between tumor grade and CD109 expression, the intensity of cytoplasmic staining, and the combined score (P = 0.003, P = 0.018, P = 0.008, respectively). No significant difference was found between the percentages of CD109 expression in patients with positive (48%) and negative (11%) lymph nodes (P = 0.058). The percentage of CD109 expression did not significantly differ in relation to overall survival (P = 0.483). CONCLUSION Comprehensive and more extensive studies are needed to examine the relationship between CD109 expression and vulvar malignant lesions.

Abstract
OBJECTIVE To assess the discrepancies that prevailed among the members of the Head and Neck Pathology Working Group in Turkey in diagnosing salivary gland tumors, classified primarily according to myoepithelial origin, by utilizing telepathology. STUDY DESIGN At least 4 representative images were obtained from each case of a total of 47 salivary gland tumors, and these were studied by 14 participants. The tumors examined were classified into 2 categories under behavior as malignant or benign, and also grouped into 2 categories under differentiation: those showing and those not showing myoepithelial differentiation. Representative areas from hematoxylin and eosin-stained slides were imaged by experienced pathologists. Images from the cases were recorded and distributed via compact disc. RESULTS The participants in this study had a mean of 12.8 years' experience in pathology. The agreement ratios on tumors showing myoepithelial differentiation and malignancy were 86% and 81%, respectively. Basal cell adenocarcinoma gathered the lowest agreement of the myoepithelial differentiation among the tumors by 64%. The highest agreement (100%) was for 17 myoepitheliomas. While adenoid cystic carcinoma attained the highest ratio (95%), myoepithelial carcinoma had the lowest ratio (47%) of agreement on malignancy among the 19 observers. Accordingly, regarding benign tumors the ratio of agreement on the benignancy was 70%, with the highest percentage being 91% for basal cell adenoma. CONCLUSION Electronic media acting as a usable technological tool for the distribution of pathology expertise may be used to obtain a second opinion about salivary gland tumors.

Abstract
The aim of the study was to establish the prognostic and predictive value of Bax and Bcl-2 proteins in conjunction with the host immune response in primary epithelial ovarian carcinoma.83 patients were evaluated. Immunohistochemical staining was performed using anti-Bcl-2 (Dako; clone 124) and anti-Bax (Springbio; E17994) monoclonal antibodies. Additionally, the number of lymphocytes within tumor stroma lymphocyte nests were counted. Bcl-2 protein expression was lower in advanced stage than early stage (p= 0.005). High (H) Bax expression was associated with longer overall survival (OS) than lower (L) Bax expression (p=0.03). The OS of the (L) Bax/(L) Bcl-2 group was shorter than (H) Bax/(L) Bcl-2 group in advanced stage (p=0.05). The platinum-sensitive group had a statistically significant tendency for high Bax expression (p=0.04). Furthermore, the intensity of the lymphocyte infiltration was associated with tumor differentiation (p= 0.003). Our data suggests that (H) Bax protein expression prolongs survival, predicts platinum sensitivity and can be used after confirmation of this hypothesis in further prospective studies. The combined evaluation of Bax and Bcl-2 protein expression may provide additional significant prognostic information. The quantity of lymphocyte infiltration could be important for prognostic outcome.

Abstract
BACKGROUND Renal vasoconstriction, activated by the renin-angiotensin system, plays a pivotal role in the pathogenesis of contrast-induced nephropathy (CIN). The purpose of this study was to evaluate the effect of aliskiren, a direct renin inhibitor, for the prophylaxis of experimental CIN in the rat. METHODS Thirty-two Wistar albino rats were divided into four groups of 8 rats each, namely the control (C), aliskiren (A), contrast media (CM) and aliskiren plus contrast media (ACM) groups. Aliskiren was given orally at a dose of 50 mg/kg/day once daily for 5 consecutive days. CIN was induced by intravenous administration of indomethacin, N-nitro-L-arginine methyl ester and high-osmolar contrast medium meglumine amidotrizoate. Renal function parameters, kidney histology and tubular expression of vascular endothelial growth factor were determined. RESULTS Mean serum creatinine was significantly lower (p < 0.001) and mean creatinine clearance was higher (p < 0.001) in the ACM group compared with the CM group. However, there were no differences between the ACM and CM groups in terms of tubular necrosis, proteinaceous casts, medullary congestion and vascular endothelial growth factor expression. CONCLUSION Our preliminary data seem to suggest a potential role of aliskiren for the prophylaxis of CIN in an experimental rat model.

Abstract
ETS-1 protein is one of the key regulators in tumor invasion and progression. We aimed to evaluate the role of ETS-1 in the invasiveness and progression of laryngeal squamous carcinoma, as well as to determine the correlations between clinicopathological characteristics and expression of this molecule. We assessed the levels of ETS-1 in a total of 96 laryngeal specimens of varying degrees of dysplasia, microinvasive squamous carcinoma (8), and invasive squamous carcinoma (60), using normal mucosal epithelium (10) as a positive control. The relationship between ETS-1 expression and clinicopathological parameters of laryngeal carcinoma was also analyzed. We found a significantly higher ETS-1 expression in invasive laryngeal squamous cell carcinomas than in dysplasia (P<0.001). A correlation between ETS-1 expression scores and grade was detected - T factor, stage, cartilage invasion, lymph node metastasis, as well as depth of invasion in laryngeal tumors. Our study is the first to demonstrate that ETS-1 expression is significantly increased in invasive carcinoma, but it is absent in low-moderate grade laryngeal dysplasia and non-neoplastic laryngeal mucosa. This data suggest that ETS-1 expression may play an important role in tumor invasion, and may function in the initiation of the invasive process in laryngeal squamous cell carcinoma.

Abstract
BACKGROUND/AIMS Contrast-induced nephropathy (CIN) remains a leading cause of iatrogenic acute renal failure. Terlipressin, a long-acting analog of vasopressin, may improve renal function. This study aimed to investigate the possible protective effect of terlipressin against the development of experimental CIN in rats. METHODS Wistar albino rats (n = 32) were allocated randomly into four equal groups of 8 each, i.e. control, terlipressin, contrast media (CM), and terlipressin plus contrast media (TCM). CIN was induced by intravenous administration of indomethacin (10 mg/kg), N-nitro L-arginine methyl ester (L-NAME, 10 mg/kg, twice at 15 and 30 min), and high-osmolar contrast media meglumine amidotrizoate 60%. Renal function parameters, kidney histology, and tubular expression of vascular endothelial growth factor (VEGF) were determined. RESULTS Mean serum creatinine levels were decreased (p < 0.05) and creatinine clearance (p < 0.05) increased in the TCM group compared with the CM group. Notably, rats in the TCM group displayed less tubular necrosis (p < 0.05), medullary congestion (p < 0.05), and a reduced tubular expression of VEGF (p < 0.05) compared with the CM group. CONCLUSION These results demonstrate that terlipressin can inhibit the development of CIN.

Abstract
In this series, laryngeal preneoplastic lesions were evaluated by the classifications of the World Health Organization (WHOC), Ljubljana (LC) and squamous intraepithelial neoplasia (SINC) by multiple observers. The inter-observer agreement (IA) by WHOC for laryngeal lesions had been previously evaluated, but to the best of our knowledge, there are no data for LC and SINC. H&E stained slides from 42 laryngeal biopsies were evaluated by fourteen participants according to WHOC and LC, and SINC was additionally applied by 6. The results were analyzed statistically. The diagnoses which were favored by most participants for each case, according to WHOC, were as follows: squamous cell hyperplasia (n = 5; 12%), mild dysplasia (n = 11; 26.2%), moderate dysplasia (n = 12; 28.6%), severe dysplasia (n = 7; 16.7%), carcinoma in situ (n = 5; 12%), and invasive squamous cell carcinoma (n = 2; 4.8%). There was a significant difference between the participants for all three classifications; some participants gave lower or higher scores than the others. The mean correlation coefficients (MCC) of the participants were higher for WHOC compared to LC (0.55 ± 0.15 and 0.48 ± 0.14, respectively). The mean linear-weighted kappa (wKappa) values of participants were not significantly different (0.42 ± 0.10, 0.41 ± 0.12 and 0.37 ± 0.07 for WHOC, LC and SINC, respectively). The kappa values in this series are in agreement with those in previous literature for WHOC, and the similar results obtained for LC and SINC are novel findings. Although the MCC of WHOC was higher, as the wkappa was not significantly different, the findings in this series are not in favor of any of the classifications for better IA for pre-neoplastic laryngeal lesions.

Abstract
We report JC virus (JCV)-associated nephropathy in a renal allograft recipient and summarize the clinical and laboratory data of the 8 previous cases. A 28-year-old male renal allograft recipient received a preemptive transplant from his father. Six months later, a kidney biopsy was performed because of deterioration of allograft function. Biopsy revealed tubulointerstitial mononuclear infiltrates with normal glomeruli; on hematoxylin and eosin staining, basophilic nuclear inclusions were seen in the nucleus of tubular cells. Urinary cytology failed to demonstrate decoy cells, but polymerase chain reaction of a urinary sample was positive for JCV 3.15 × 10(10) copies/mL. Additionally, polyomavirus (SV40) immunohistochemical staining was performed and was positive in the enlarged nuclei of tubular epithelial cells in the kidney biopsy sample. After the diagnosis of polyomavirus-associated nephropathy (PVAN) was confirmed by kidney biopsy, immunosuppressive agents were reduced. Intravenous immunoglobulin was administered 5 times at a dose of 500 mg/kg every other 3 weeks. Two months after diagnosis, the serum creatinine became stable and urinary viral load of JCV was decreased. Because viruria was still present, tacrolimus was converted to sirolimus. Four months after immunosuppressive agent conversion from tacrolimus to sirolimus, the viruria had disappeared. Review of the literature and our case demonstrates that male gender, previous acute rejection episode, low incidence of JCV viremia, PVAN pattern B histology, and reducing immunosuppression are the diagnostic touchstones for PVAN due to JCV.

Abstract
Hereditary spherocytosis is a familial hemolytic anemia. Immunoglobulin A (IgA) nephropathy associated with hereditary spherocytosis has not been reported in children. Here, we report a case of a 17-year-old boy with IgA nephropathy and hereditary spherocytosis. The patient was diagnosed with hereditary spherocytosis at the age of 12 years and splenectomy was done at the age of 15 years. Later, the patient presented with macroscopic hematuria and proteinuria. Kidney biopsy of the boy was consistent with IgA nephropathy. Treatment with angiotensin-converting enzyme inhibitor was started. The patient became free of proteinuria after the 6th month of therapy.

Abstract
AIM Primary type I membranoproliferative glomerulonephritis (MPGN) is a rare cause of glomerular disease with a high relapse rate and poor prognosis. The aim of this study was: (i) to evaluate the histopathological findings associated with remission; and (ii) to document the possible clinical and histopathological factors predicting relapses. METHODS Eleven type I MPGN patients (five men, six women; mean age, 38.8+/-13.5 years) who were in remission for at least 1 year after the cessation of immunosuppressive drugs were re-biopsied. The intensity of immunostaining for tumor necrosis factor (TNF)-alpha, transforming growth factor (TGF)-beta1, and tenascin was graded from 0 (no staining) to 3+ (maximum staining). RESULTS Mean baseline mesangial cellularity score and tubulointerstitial infiltration score were reduced and mesangial matrix expansion score was increased at protocol re-biopsies compared to baseline. The glomerular and tubulointerstitial staining scores for TGF-beta1 and tenascin were higher than that of baseline. Reduced tubulointerstitial TNF-alpha expression was found in re-biopsy specimens compared to baseline. Patients have been followed for a mean time of 51.5+/-22.2 months after the protocol biopsy. Eight patients had a relapse. Mesangial cellularity score and glomerular tenascin expression at re-biopsy specimens were higher in relapsed patients compared to those without a relapse. CONCLUSION Our study shows that mesangial cellularity and tubulointerstitial cell infiltration are reducing whereas mesangial matrix expansion, glomerular and tubulointerstitial TGF-beta1 and tenascin expression are increasing with remission. The higher mesangial cell proliferation and glomerular tenascin scores in remission are associated with the development of relapse.

Abstract
BACKGROUND Patients with resistant or relapsing primary glomerulonephritis (PGN) after conventional immunosuppressive treatment have a worse renal outcome, and treatment of these patients remains problematic. In this study we aimed to determine the effect of tacrolimus in these patients. METHODS We prospectively studied 15 patients with PGN (3 membranous nephropathy, 6 membranoproliferative GN, 4 focal segmental glomerulosclerosis [FSGS], 1 IgA nephropathy and 1 IgM nephropathy) who were either resistant (n=7) or relapsing (n=8) after or during conventional immunosuppressive therapy. Tacrolimus was started at a dosage of 0.05 mg/kg per day. Prednisolone was either maintained or added to the tacrolimus regimen. RESULTS The mean duration of tacrolimus treatment was 28.9 +/- 2.4 months. Proteinuria decreased from 6.3 +/- 5.0 g/day to 0.5 +/- 0.6 g/day at the end of follow-up (p=0.001). Complete or partial remission was achieved by 60% and 40% of patients, respectively. Relapse occurred in only 2 patients with FSGS under tacrolimus treatment. There was no significant change in serum creatinine at the end of follow-up (from 1.4 +/- 1.0 mg/dL to 1.2 +/- 0.6 mg/dL, p=0.3). Serum albumin increased from 3.2 +/- 0.5 g/dL to 4.3 +/- 0.3 g/dL (p=0.0001). There were 6 relapses among 10 patients after the withdrawal of tacrolimus. CONCLUSIONS These data suggest that the combined therapy of tacrolimus and low-dose prednisolone may have a promising role to obtain long-term remission in resistant or relapsing PGN.

Abstract
Nephrotic syndrome occurs very rarely, about 0.012-0.025% of all pregnancies. Here, we report a rare case of early onset nephrotic syndrome developing de novo in the 17th week of pregnancy. A renal biopsy was done and the specimens revealed typical features of focal segmental glomerulosclerosis. The patient had a progressive clinical course of disease despite steroid treatment. Suffering from severe intrauterine growth restriction, the fetus died in utero. After delivery, steroid treatment was continued. The patient had normal renal function with a decrease in proteinuria in the second and fifth month postpartum. This report points out the poor fetal prognosis associated with an early onset nephrotic syndrome. Pregnant patients with early onset nephrotic syndrome should be carefully evaluated for the presence of chronic renal disease, and primary renal pathology should be included in the differential diagnosis of massive proteinuria in early pregnancy.

Abstract
Bone morphogenetic protein 7 (BMP 7) is a member of the transforming growth factor (TGF) beta superfamily and is involved in regeneration, repair, and development of specific tissues, for example kidney, gut, lens, and skeleton. BMP 7 has emerged as a renotrophic factor and experimental studies have shown its protective role against fibrotic processes. Tubulointerstitial changes are present in the pyelonephritic kidney which progresses to fibrosis. Renal fibrosis may lead to significant morbidity in the form of hypertension, proteinuria, and loss of renal function. The objective of this study was to investigate BMP 7 expression in experimental acute and chronic pyelonephritis models. Eighteen Wistar rats were injected with 0.1 mL solution containing E. coli ATCC 25922 10(10) cfu mL(-1) into left renal medullae. Six rats were used as a sham group and were given 0.1 mL 0.9% NaCl. Pyelonephritic rats were sacrificed 24 h (group I, n=6), 1 week (group II, n=6), and 6 weeks (group III, n=6) after E. coli injection. Serum creatinine levels were analyzed. Renal tissues were studied histopathologically by use of hematoxylin and eosin and scored for diagnosis of pyelonephritis. BMP 7 expression was studied semiquantitatively by immunohistochemical staining. Acute (group I) and chronic (group II and group III) pyelonephritic histopathological changes were observed in experimental pyelonephritic groups. A gradual decrease in BMP 7 expression was observed in the tubulointerstitial and tubular area of the pyelonephritic kidneys, mildest in the acute pyelonephritic group and most severe in the chronic pyelonephritic 6th week group. A statistically significant difference was observed between tubulointerstitial BMP 7 expression by groups I and III (P=0.017) and by groups III and IV (P=0.000). Tubular BMP 7 expression was statistically significantly different between groups II and IV (P=0.009) and between groups III and IV (P=0.002). The data imply that BMP 7 has a major role in chronic pyelonephritis. Tubulointerstitial and tubular BMP 7 expression also had a significant negative correlation with fibrosis, tubular, atrophy, and vascular changes. Serum creatinine levels of the study group were all normal. We conclude that the decrease in renal BMP 7 expression in experimental chronic pyelonephritis is one of the factors responsible for fibrotic changes in persistent renal damage.

Abstract
BACKGROUND Vascular endothelial growth factor (VEGF) is a prognostic factor in breast cancer. One of the mechanisms of extra-skeletal uptake of Tc-99m-methylenediphosphonate (MDP) is suggested to be tumor vascularity. We studied the correlation between MDP uptake and VEGF and compared the diagnostic accuracy of mammography versus MDP-scintimammography (MDP-S). MATERIALS AND METHODS Fifty-four patients with suspicion of breast cancer were evaluated. Breast images were collected 5-10 minutes after injection of Tc-99m-MDP prior to biopsy. Tissue slides were stained using a rabbit-polyclonal anti-VEGF. RESULTS MDP-S showed a diagnostic accuracy of 83.3% in BIRADS category 4 lesions. Four out of 23 benign lesions were false-positive. The tumor to background (TM/BG) ratio of early images of MDP-S was correlated with VEGF staining (p: 0.014) and with tumor size (p: 0.006). CONCLUSION Early images of Tc-99m-MDP-S may satisfactorily identify cancers with increased neovascularization. MDP-S seems to be an accurate imaging modality, especially in BIRADS category 4 lesions.

Abstract
A 48-year-old male patient having none of the known risk factors for atherosclerosis underwent coronary artery bypass graft (CABG) surgery because of double-vessel coronary artery disease. During the operation, the aorta, both internal thoracic arteries (L/R-ITA), and the femoral artery were sclerotic, and CABG was performed using only saphenous vein grafts. A diagnosis of tertiary syphilis had been confirmed by either microscopic or serologic tests. There were different degrees of sclerosis in different arteries of different sizes. The presence of coronary artery disease with no known atherosclerotic risk factors should include preoperative testing for connective tissue disorders, chronic inflammatory disease, and cold hemagglutinins, because of the possible use of obligatory deep hypothermia or total circulatory arrest due to a diseased ascending aorta.

Abstract
Pleura, diaphragm, pericardial fat pad, intercostal muscles and omentum can be used to protect and revascularize the bronchial suture line. To compare the efficiency of pleura, diaphragm and omentum, an experimental study was designed. Heterotopic tracheal autotransplantation was performed in 15 rats. Animals were divided into three groups; omentum, diaphragm and pleura. Tracheal Segment Necrosis Scoring System was used for pathologic examinations. Pleural and diaphragmatic groups showed the least necrosis and there was significant statistical difference among these groups and omental group (P < 0.05). Our study showed that pleura and diaphragm could be used as safely as omentum for protection and survival of bronchial suture lines.
