Publication Multicystic dysplastic kidney: Four-year evaluation(Türk Patoloji Derneği, 2011-01-01) Aytaç, Berna; Şehitoğlu, İbrahim; Vuruşkan, Hakan; AYTAÇ VURUŞKAN, BERNA; Şehitoğlu, İbrahim; VURUŞKAN, HAKAN; Tıp Fakültesi; Üroloji Ana Bilim Dalı; AAH-9746-2021; ABF-8955-2021; EFH-9523-2022Objective: Multicystic dysplastic kidney is a relatively common developmental abnormality in infants and children. Additional abnormalities like vesicoureteral reflux, ureteropelvic junction obstruction, and ureterovesical junction obstruction may accompany multicystic dysplastic kidney. In this article, we reviewed the pathogenesis, diagnosis, associated urinary tract anomalies and results of management of multicystic dysplastic kidney in the light of the literature.Material and Method: We retrospectively assessed 20 children with unilateral multicystic dysplastic kidney between January 2005 and December 2009. Mean duration of follow-up was 35 +/- 8.7 months. All children with multicystic dysplastic kidney underwent nephrectomy. Patient characteristics, the pathology findings, associated urinary tract anomalies and results of management were reviewed.Results: Abdominal ultrasound, voiding cystourethrography and renal scintigraphy revealed vesicoureteral reflux in 3 (15%) children, ureteropelvic junction obstruction in 3 (15%) children, and a duplex system in the contralateral kidney in 1 (5%) child. Blood pressure values, serum urea, creatinine and urinalysis were within normal range in all children during follow-up.Conclusion: A conservative approach to children with multicystic dysplastic kidney has been advocated, but surgical removal is also another management modality on the basis of risk of hypertension, mass effect, potential for malignant change, and cost of repeated ultrasound examination.Publication Pediatric multilocular cystic nephroma extending into the renal pelvis and ureter(Galenos Yayıncılık, 2014-11-01) Doğan, Hasan Serkan; Yazıcı, Zeynep; Aytac, Berna; Sevinir, Betül; Erdoğan, Hakan; Çiçek, Çağatay; YAZICI, ZEYNEP; AYTAÇ VURUŞKAN, BERNA; SEVİNİR, BETÜL BERRİN; ÇİÇEK, MEHMET ÇAĞATAY; Tıp Fakültesi; Üroloji Ana Bilim Dalı; AAH-1570-2021; AAI-2303-2021; AAH-9746-2021; JLG-1312-2023Multilocular cystic nephroma (MCN) is a rare tumor at the most benign end of the spectrum of the multilocular cystic neplasms of kidney. Nephrectomy is curative for MCN. In this case-report, we present a 16-month-old girl with a 10x15 cm multilocular cystic renal tumor extending into the renal pelvis and proximal ureter on the right side demonstrated on magnetic resonance imaging. Nephrectomy was performed. The pathology was completely consistent with MCN.Publication RNA-based markers in biopsy cores with atypical small acinar proliferation: Predictive effect of T2E fusion positivity and MMP-2 upregulation for a subsequent prostate cancer diagnosis(Wiley, 2019-02-01) Eryılmaz, I. Ezgi; Vuruşkan, Berna Aytaç; Kaygısız, Onur; Egeli, Ünal; Tunca, Berrin; Kordan, Yakup; Çeçener, Gülşah; ERYILMAZ, IŞIL EZGİ; AYTAÇ VURUŞKAN, BERNA; KAYGISIZ, ONUR; TUNCA, BERRİN; ÇEÇENER, GÜLŞAH; Tıp Fakültesi; Tıbbi Patoloji Ana Bilim Dalı; 0000-0002-9790-7295; 0000-0001-7904-883X; 0000-0002-1619-6680; 0000-0002-9947-848X; 0000-0002-3820-424X; ABI-6078-2020; AAP-9988-2020; AAH-1420-2021; L-9439-2019; AAM-9726-2020; AAH-9746-2021; GWV-3548-2022Background Atypical small acinar proliferation (ASAP) is a precursor lesion of prostate cancer (PC), and PC develops from this suspicious focus or an unsampled malignant gland nearby. However, PC-related molecular alterations that could guide the timing of repeat biopsies and help monitor PC risk in ASAP-diagnosed patients have not been investigated. The purpose of this study was to first investigate the expression of seven different PC-related RNAs that included serine 2 (TMPRSS2): erythroblastosis virus E26 oncogene homolog (ERG) gene (TMPRSS2-ERG, T2E) fusion, alpha-methylacyl-CoA racemase (AMACR), kallikrein related peptidase 3 (KLK3), androgen receptor (AR), prostate cancer specific antigen 3 (PCA3), and matrix metalloproteinases (MMP)-2 and 9. Methods PC-related RNAs were evaluated using a real-time quantitative reverse transcription polymerase chain reaction (RT-qPCR) system in pathologically ASAP-diagnosed prostate biopsy cores from 55 patients presenting with a normal digital rectal examination and a PSA level of 4-10 ng/mL. Results We detected that positive T2E fusion status (P = 0.013) and the expression of AMACR (P = 0.016), AR (P = 0.016) and MMP-2 (P = 0.013) were independently and significantly associated with PC risk in ASAP patients. There were also several statistically significant correlations between expression levels. Additionally, we demonstrated that T2E fusion positive ASAP patients with higher MMP-2 expression were more likely to be diagnosed with PC at a subsequent biopsy during the follow-up period (P = 0.003). Conclusions Although, more clinical validations are needed for the stratification of PC risk in ASAP-diagnosed biopsy cores, our current results indicate that the coexistence of T2E fusion positivity with MMP-2 upregulation may help clinicians adjust their biopsy timetable and/or assessment of PC risk in ASAP-diagnosed patients with a PSA level of 4-10 ng/mL.Publication Effects of combination therapy with captopril and angiotensin ii on the viability of random-pattern skin flaps in diabetic rat model(Wolters Kluwer Medknow Publications, 2016-12-01) Atalay, Fatma Öz; ÖZ ATALAY, FATMA; Vuruşkan, Berna Aytaç; AYTAÇ VURUŞKAN, BERNA; Akın, Selçuk; AKIN, SELÇUK; Aygören, Binevs Heja; Tıp Fakültesi; Patoloji Ana Bilim Dalı; 0000-0002-7188-6115; AAH-9746-2021Objective: Diabetes mellitus leads to tissue damage by erythrocyte aggregation and an endothelial dysfunction-mediated disturbance in vascularization. These mechanisms facilitate the formation of skin wounds. As skin flaps are often used in the treatment of diabetic wounds, enhancing the blood supply and lowering blood glucose levels have emerged as important factors to increase the success of treatment using skin flaps. Therefore, in this study, the effectiveness of captopril and angiotensin II treatments were investigated to determine if they increased blood flow to skin flaps to protect their viability in an experimental diabetic rat model.Material and Methods: The experiment was conducted using 45 rats. Nine constituted the sham group, whereas diabetes was induced in 36 of them by an intraperitoneal injection of streptozotocin. Skin flaps (3x8 cm in diameter) were prepared, separated, and consequently reimplanted with staplers to their original place at the dorsum of the rats. Diabetic rats were treated with saline (n=9), angiotensin II (n=9), captopril (n=9), captopril+angiotensin II (n=9) during the postoperative period. Flap viability was assessed by clinical and histopathological findings.Results: The percentage of flap viability in diabetic rats was found to be significantly higher in the captopril+angiotensin II group than in the captopril group and was lowest in the angiotensin II group. Additionally, both individual and combined use of captopril and angiotensin II were found to increase the intensity of blood vessels compared to the administration of saline alone in diabetic rats.Conclusion: Our study showed that the use of captopril and angiotensin II could increase the viability of skin flaps in diabetic rats.Publication Prognostic value of estrogen receptors in patients who underwent prostatectomy for non-metastatic prostate cancer(Spandidos Publ Ltd, 2023-02-01) Aydın, Yavuz Mert; Şahin, Ahmet Bilgehan; Dölek, Rabia; Vuruşkan, Berna Aytaç; Ocakoğlu, Gökhan; Vuruşkan, Hakan; Yavaşçaoğlu, İsmet; Coşkun, Burhan; AYDIN, YAVUZ MERT; ŞAHİN, AHMET BİLGEHAN; DÖLEK, RABİA; AYTAÇ VURUŞKAN, BERNA; OCAKOĞLU, GÖKHAN; VURUŞKAN, HAKAN; YAVAŞCAOĞLU, İSMET; COŞKUN, BURHAN; Tıp Fakültesi; Tıbbi Onkoloji Ana Bilim Dalı; 0000-0002-6287-6767; 0000-0002-7846-0870; 0000-0002-1114-6051; 0000-0002-8242-9921; AAH-9704-2021; AFP-3055-2022; HSH-9815-2023; JCO-5169-2023; AAH-5180-2021; AAM-4927-2020; EEJ-1452-2022; EFH-9523-2022; EIN-0828-2022Estrogen receptors in prostate cancer (PCa) are a subject of debate. The aim of the present study was to investigate whether estrogen receptor-alpha (ER alpha) and estrogen receptor-beta (ER beta) impact the biochemical recurrence (BCR) of non-metastatic PCa after surgery. Following the application of the exclusion criteria, data from 108 patients who underwent laparoscopic radical prostatectomy between January 2011 and December 2019 were retrospectively evaluated. A total of 36 patients with BCR constituted the BCR group. The control group was formed using the Propensity Score Matching (PSM) method with a 1:2 ratio, including parameters with well-studied effects on BCR. The median follow-up time was 74.3 (range, 30-127.5) months in the BCR group and 66.6 (range, 31.5-130) months in the control group. Pathology specimens from the two groups were immunohistochemically stained with ER alpha and ER beta antibodies. Logistic regression analysis and survival analysis were performed. No differences in clinicopathological characteristics were detected between the two groups. The patients with ER alpha(-)/ER beta(+) staining results had a significantly fewer BCRs than other patients (P=0.024). In the logistic regression analysis, patients with ER alpha(-)/ER beta(+) PCa also had a significantly lower risk of recurrence (P=0.048). In the survival analysis, the 5-year BCR-free survival rate of patients with ER alpha(-)/ER beta(+) PCa was higher than that of other patients (85.7 vs. 66.1%; P=0.031). Excluding the effects of well-studied risk factors for recurrence by the PSM method, the present study showed that ER alpha and ER beta have prognostic value for non-metastatic PCa. The 5-year BCR-free survival rate is significantly higher in patients whose PCa tissue has ER alpha(-)/ER beta(+) staining results.Publication Investigation of VHL gene associated with miR-223 in clear cell renal cell carcinoma(Springer, 2021-11-26) Ünal, Ufuk; Çeçener, Gülşah; Ünlü, Havva Tezcan; Vuruşkan, Berna Aytaç; Erdem, Ecem Efendi; Egeli, Ünal; Nazlıoğlu, Hülya Öztürk; Kaygısız, Onur; Tunca, Berrin; Vuruşkan, Hakan; Ünal, Ufuk; ÇEÇENER, GÜLŞAH; Ünlü, Havva Tezcan; AYTAÇ VURUŞKAN, BERNA; Erdem, Ecem Efendi; EGELİ, ÜNAL; ÖZTÜRK NAZLIOĞLU, HÜLYA; KAYGISIZ, ONUR; TUNCA, BERRİN; VURUŞKAN, HAKAN; Tıp Fakültesi; Tıbbi Biyoloji Ana Bilim Dalı; 0000-0003-4913-3616; 0000-0002-3820-424X; 0000-0002-0910-4258; 0000-0001-7904-883X; 0000-0002-9790-7295; 0000-0002-1619-6680; AAH-1420-2021; L-9439-2019; GYU-0252-2022; ABC-1357-2020; AAP-9988-2020; GYU-0252-2022; EEJ-1452-2022; ESY-2704-2022; FLN-9596-2022; ABI-6078-2020; EFH-9523-2022Background Clear cell type renal cell carcinoma (ccRCC) is the most common renal cell carcinoma (RCC). In this study, we examined the expressions of VHL and miR-223 in ccRCC patients' tissues to investigate the possible role in the development of ccRCC.Methods and results This study collected five expression profiles (GSE36139, GSE3, GSE73731, GSE40435, and GSE26032) from Gene Omnibus Data. Expressions of VHL and miR-223 in paraffinized tumor and normal tissues of 100 Turkish patients' ccRCC tissues were determined by bioinformatic data mining and real-time quantitative polymerase chain reaction (qRT-PCR). The VHL gene was subjected to mutational analysis by DNA sequencing, and pVHL was analyzed using western blotting. Our study's t-test and Pearson correlation analysis showed that VHL gene expression in tumoral tissues with a - 0.39-fold decrease was not significantly lower than normal tissues (p = 0.441), and a 0.97-fold increase miR-223 (p = 0.045) was determined by real-time PCR. Also, as a result of DNA sequence analysis performed in the VHL gene, it was found that 26% of the patients have mutations. The mutations for (VHL):c.60C>A (p.Val20=) and (VHL):c.467delA (p.Tyr156Leu) was detected for the first time in Turkish patients.Conclusions The present study demonstrated that the differences in the expression levels of miR-223 have the potential to be biomarkers to determine the poor prognosis in ccRCC.Publication Paricalcitol protects peritoneal membrane function in encapsulating peritoneal sclerosis(Türk Nefroloji Diyaliz Transplantasyon Dergisi, 2016-01-01) Gül, Cuma Bülent; Yıldız, Abdülmecit; Vuruşkan, Berna; Gül, Özen Öz; Oruç, Ayşegül; Aktaş, Nimet; Ersoy, Alparslan; Güllülü, Mustafa; Dilek, Kamil; Yavuz, Mahmut; Yurtkuran, Mustafa Abbas; YILDIZ, ABDULMECİT; AYTAÇ VURUŞKAN, BERNA; ÖZ GÜL, ÖZEN; ORUÇ, AYŞEGÜL; ERSOY, ALPARSLAN; GÜLLÜLÜ, MUSTAFA; DİLEK, KAMİL; YAVUZ, MAHMUT; Yurtkuran, Mustafa Abbas; Tıp Fakültesi; Endokrinoloji ve Metabolizma Ana Bilim Dalı; 0000-0002-0710-0923 ; 0000-0002-0342-9692; HIG-9032-2022; AAH-9746-2021; AAI-1005-2021; AAH-4002-2021; AAH-5054-2021; JGS-9425-2023; EUF-5229-2022; EHM-7377-2022; IPP-3337-2023OBJECTIVE: The most lethal complication of peritoneal dialysis is encapsulating peritoneal sclerosis (EPS), which develops as a result of epithelio-mesenchymal transformation (EMT) and known fibrotic processes. Paricalcitol has previously been shown to inhibit both EMT and fibrosis. We investigated the effect of paricalcitol on EPS.MATERIAL and METHODS: Forty non-uremic albino Wistar rats divided into four groups of equal numbers. The first group was administered 2 mL saline intraperitoneally (IP) and the second group was administered 2 mL of 200 gram chlorhexidine gluconate (CG) (0.1%) dissolved in saline and ethanol (15%) IP. The treatment groups received CG for three weeks in addition to subcutaneous paricalcitol at a dose of 0.2 mcg/kg/day to the third group and 0.4 mcg/kg/day to the fourth group. A one-hour peritoneal equilibration test was performed with 25 mL 3.86% PD solution at the end of the study. Peritoneal membrane and intracardiac blood samples were obtained.RESULTS: D/P urea was significantly low in both treatment groups when compared to group 2 (p<0.05). Paricalcitol co-treatment recovered ultrafitration failure and peritoneal membrane thickness was better paricalcitol groups but there was no statistically significant difference between the groups. Serum calcium, phosphorus and parathyroid hormone levels were similar in all groups.CONCLUSION: Paricalcitol can be effective in the protection of peritoneal functions.Publication Aa amyloidosis presenting with acute kidney injury, curable or not?(Turkish J Pediatrics, 2022-07-01) Uysal, Berfin; Vuruşkan, Berna Aytaç; AYTAÇ VURUŞKAN, BERNA; Tıp Fakültesi; Patoloji Ana Bilim DalıBackground. Amyloidosis is a group of disorders with extracellular accumulation of autologous fibrillary insoluble proteins in various tissues and organs such as the kidneys, liver, spleen, heart and gastrointestinal tract leading to impairment of normal organ function. Childhood amyloidosis is an exceedingly rare entity mainly caused by familial Mediterranean fever (FMF) and the other autoinflammatory diseases such as mevalonate kinase deficiency (MKD).Case. A 16-year-old male was referred to pediatric nephrology for coincidentally discovered proteinuria. He had no significant findings on physical examination except for urochromic color. He had nephrotic range proteinuria with 109 mg/m2/h and serum creatinine was 1.35 mg/dl. Kidney biopsy was performed because of nephrotic range proteinuria with acute kidney injury. In hematoxylin-eosin-stained tissue sections, amyloid was suggested as extracellular amorphous material that is lightly eosinophilic in the glomeruli. Diagnosis was confirmed by Congo red positivity, with apple-green birefringence under polarized light. MEFV gene mutation was negative and a compound heterozygote mutation found in mevalonate kinase gene. A 6-month -trial of colchicine, enalapril, and losartan combination was not successful; Canakinumab was started thereafter. Proteinuria and creatinine decreased to 7 mg/m2/h and 0.6 mg/dl respectively 4 years after treatment. Conclusions. Amyloidosis should be considered especially in children presenting with proteinuria and with a history of recurrent fever. This report also emphasizes the efficacy of canakinumab to prevent or decelerate chronic renal failure in these patients although it does not reduce tissue deposition in long-term use.Publication Evaluation of incidence and histolopathological findings of soft tissue sarcomas in genitourinary tract: Uludag University experience(Brazilian Soc Urol, 2019-01-01) Vuruşkan, Berna Aytaç; Özşen, Mine; Coşkun, Burhan; Yalçınkaya, Ülviye; AYTAÇ VURUŞKAN, BERNA; ÖZŞEN, MİNE; COŞKUN, BURHAN; YALÇINKAYA, ÜLVİYE; Tıp Fakültesi; Cerrahi Patoloji Ana Bilim Dalı; 0000-0002-5771-7649; 0000-0002-8242-9921; AAI-1609-2021; JCO-5169-2023; AAH-8924-2021; AAH-9746-2021; AAH-9704-2021Purpose: In this study we aimed to review urological soft tissue sarcomas of genitourinary tract that were diagnosed in our institution and their prognostic factors for survival.Materials and Methods: The clinical and pathological records of 31 patients who had diagnosis of soft tissue sarcomas primarily originating from the genitourinary tract between 2005-2011 were reviewed.Results: The most common site was kidney (17 cases, 54.8%), and most common diagnosis was leiomyosarcoma (11 cases, 35.4%). A total of 24 patients (77.4%) had surgical excision. The surgical margins were positive in 7 patients who presented with local recurrence after primary resection. Twelve patients developed metastatic disease. During follow-up (range 9-70 month), 26 of the 31 patients (88.9%) were alive. Significant survival differences were found according to histological type (p: 0.001), with lower survival rates for malignant fibrous histiocytoma. The tumor size, the presence of metastasis at the time of diagnosis and tumor localization were not statistically significant for overall survival.Conclusions: In our series, prostate sarcomas, paratesticular rhabdomyosarcoma and malignant fibrous histiocytoma had poor prognosis, especially in patients presenting with metastatic disease.Publication Low-grade injury following testicular torsion: A multicenter study confirming a disturbing possibility(Karger, 2023-12-01) Çiğsar Kuzu, Emine Burcu; Tiryaki, Sibel; Güney, Neslihan; Polatdemir, Kamer; Çakır, Yasemin; Karagözlu Akgül, Ahsen; Toper, Muhammed Hasan; Karaguzel, Güngör; Uçar, Murat; Başsorgun, Cumhur İbrahim; Özel, Seyhmus Kerem; Özkanli, Şeyma; Salcı, Gül; Aydın Mungan, Sevdegül; Yılmaz, Mehmet Uğur; Aytaç Vuruşkan, Berna; Yagmur, Ismail; Tarini, Emine Zeynep; Kaba, Meltem; Tanik, Canan; Canbaz, Furkan Adem; Hurdogan, Ozge; User, Idil Rana; Orhan, Diclehan; Atici, Ahmet; Gursoy, Didar; Yagmurlu, Emin Aydin; Enneli, Duygu; Kilic, Seref Selcuk; Erdogan, Seyda; YILMAZ, MEHMET UĞUR; AYTAÇ VURUŞKAN, BERNA; Tıp Fakültesi; Patoloji Ana Bilim Dalı; GRA-7433-2022; EEJ-1452-2022Introduction: There is an ongoing debate whether to perform orchiectomy or orchidopexy following testicular torsion (TT) in cases where the testis seems non-viable. The main problem is lack of objective criteria defining testicular viability. The aim of this study was to investigate the grade of injury in orchiectomy specimens obtained from cases of TT and its association with clinical findings. Methods: This multicenter retrospective study involved double-blinded reassessment of the patient files and the pathological specimens using Mikuz classification to analyze the relation between clinical and pathological findings. Results: A total of 289 patient charts from 14 centers were reviewed and 228 were included in this study. Twenty (8.8%) patients had grade 1 injury which refers to reversible injury. The clinical findings of these 20 patients were compared to 208 patients with higher grades of injury. As expected, there was statistically significant difference regarding duration of symptoms (p < 0.001); however, range was wide in both groups (as long as 96 h for grade 1 and as short as 7 h for higher grades). There was no statistically significant difference in any other variable including age (median 14 for both, p = 0.531), symptoms (pain: 19/20 vs. 189/202, p = 0.801; swelling: 13/19 vs. 168/197, p = 0.094), absence of blood flow in Doppler US (15/19 vs. 164/197, p = 0.635), or degree of torsion (median 720(degrees )for both, p = 0.172). Conclusion: Our study revealed necessity for better criteria to define viability of testis following TT. Histopathological injury appeared to be reversible even in some patients with more severe perioperative findings, late admission, or high degree of twisting. Our findings support the tendency for testicular fixation instead of orchiectomy as none of the clinical or perioperative findings could be attributed to high-grade injury.
