Item Complications and specimen quality in transrectal ultrasound guided prostate biopsy: Comparison of 16G and 18G needles(2020) Bayraktar, Ahmet Murat; Olcucuoglu, Erkan; Hasirci, Eray; Nalbant, Ismail; Yesil, Suleyman; 0000-0002-4147-2966; AAI-7997-2021Objectives: To evaluate specimen quality, pathological results, complications and pain in transrectal ultrasound (TRUS) guided prostate biopsy using 16 gauge (G) or 18G biopsy needles Design: Retrospective study Setting: Turkiye Yuksek Ihtisas Training and Research Hospital, Ankara, Turkey Subjects: Retrospective analysis of 243 TRUS guided prostate biopsies between March 2011 and April 2016 Interventions: Group 1 (n=121) underwent TRUS guided prostate biopsy using a 16 G needle and Group 2 (n=122) underwent TRUS guided prostate biopsy with an 18 G-needle. Main outcome measures: We compared two biopsy needle sizes (16G vs 18G) in relation to sample quality, prostate cancer detection rate, pain, bleeding and infection rates in 243 patients. Core fragmentation and short specimen length (<10mm) rate were the sample quality criteria. Pain was evaluated using visual analog scale (VAS). Results: There were no statistically significant differences in mean patient ages, prostate-specific antigen values and prostate volumes between groups 1 and 2. Sixteen gauge needles caused significantly less fragmentation of the biopsy cores when compared to 18G needles (p=0.00), but no statistically significant difference between two groups was recorded for pathological results (p=0.72) and shorter specimen length (p=0.567). Haematuria, rectal bleeding and infection were similar in both groups. Mean VAS score of group 1 was significantly greater than that of group 2 (3.19 vs 2.66;p=0.027). Conclusion: Though thicker needles provided better sampling quality, the cancer detection rate was not altered by the needle size. Also, even though complication rates were similar for different needle sizes, the 18G needles were better tolerated.Item Stereotaxic Biopsy Experience(2020) Dere, Umit Akin; Sahinturk, Fikret; Sonmez, Erkin; Gulsen, Salih; Yilmaz, Cem; Altinors, Mehmet NurAim: To review the outcomes and complications of stereotactic biopsy procedures performed at Neurosurgery Department of Baskent University and make an overall evaluation of the stereotactic biopsy system. Materials and Methods: Medical files of 151 patients who underwent stereotaxic biopsy procedure between 1996 and 2018 were retrospectively analyzed.The , age and gender of the patients, intracranial localization of the lesion and histopathologic diagnosis were evaluated. Result: The series included 84(55.6%) males and 67 (44.4%) females. The average age was 47.7 and the age spectrum was between 26-84 years of age. In 102 cases (67.55%) lesions had lobar localization and in 42 lesions (27.82%) the pathology was deep seated lesion. In 7(4.6 %) there were multiple lesions. A histopathologic diagnosis was obtained in 125 (82.79 %) cases. In 16 (%10.59 %) it was reported as brain tissue and in 10 cases (6.62 %) the histopathologic diagnosis was gliosis. A second stereotactic bipsy procedure was performed in 8 cases while in one patient a third biopsy became necessary. Thirteen patients underwent craniotomy and tumor excision as further therapy. Conclusion: Stereotactic biopsy sampling of intracranial space occupying lesions is a safe, simple and highly diagnostic method. In some cases it may contribute to further therapy. The problems encountered are inconclusive diagnosis, inadequate representation of the specimen due to its limited nature and some technical difficulties.Item Rapidly Progressive Renal Failure in AA Amyloidosis: A New Clinical and Histopathological Entity for an Old Disease(2020) Celebi, Zeynep Kendi; Kiremitci, Saba; Sadioglu, Rezzan Eren; Keven, Kenan; 0000-0003-3279-9796; ABB-9570-2020Objective: Secondary renal AA amyloidosis (RAAA) presents with proteinuria and/or as nephrotic syndrome and progresses to end stage renal disease (ESRD) insidiously. However, some patients with secondary amyloidosis show a more rapid renal disease progression than the usual course. In this study, we aimed to investigate the underlying cause of the rapidly progressive renal disease in the patients with secondary amyloidosis. Materials and Methods: Patients with kidney biopsy proven secondary RAAA were divided into 2 groups: the rapidly progressive group (estimated glomerular filtration rate >60 mL/min, who needed renal replacement therapy within one year of diagnosis) and the control group. Biopsy specimens were reevaluated for glomerular-vascular amyloid load, tubular atrophy, interstitial fibrosis, and interstitial inflammation. The biopsy characteristics and biochemical parameters were compared between the groups. Results: Histopathological examination showed global amyloid deposition, vascular pole involvement, peritubular capillary amyloid deposition, and severe interstitial inflammation associated with rapidly progressive disease. Estimated glomerular filtration rate was lower and proteinuria was higher in the rapidly progressive group than in the control group. Vascular pole amyloid deposition was found to be a predictor of ESRD in multivariate analysis. Conclusion: This study shows that higher amyloid deposition and severe inflammation revealed in in kidney biopsy of secondary RAAA cases can be risk factors for rapidly progressive renal failure.Item Prostate Biopsy in the Elderly: Histologic Findings and Treatment Necessity(2014) Akman, Ramazan Yavuz; Koseoglu, Hikmet; Oguzulgen, Ahmet Ibrahim; Sen, Erhan; Yaycioglu, Ozgur; 25374232The aim of this study is to determine results of high prostate specific antigen (PSA) or abnormal digital rectal examination driven prostate biopsies performed in our Department in men aged 75 or more and to show the characteristics of pathology results. The hospital records of the patients who had high PSA or abnormal digital rectal examination driven prostate biopsy in two common university based research hospitals have been reviewed retrospectively. Patients aged 75 years or older at the date of biopsy whose records provided pathology results and full medical history were evaluated for the study. A total of 103 patients were evaluated with a mean age of 79.4 +/- 3.4 years. More than half of the patients (55.1%) were in their seventh decade and the rest were in the eighth decade. Median PSA value was 15.0 (range 2.1-4500) ng/ml. In most of the biopsies (67%), PSA levels were lower than 20 ng/ml. In almost half of the patients (48%), digital rectal examination was abnormal. In 68.9% of the patients, there were at least one or more associated co-morbid diseases. Gleason scores were 7 or higher in 73%, and 8 or higher in 37% of the patients with prostate cancer. Four of the 70 (6%) patients had bone metastases. Castrations were applied to most of the patients with prostate adenocarcinoma (% 79). High percentage of high grade (Gleason 7 or more) prostate adenocarcinoma in the elderly refutes the perception of prostate cancer in this age group as clinically insignificant. Therefore, it is to be kept in mind that prostate cancer in the elderly an be clinically significant and prostate biopsies are to be performed when necessary.Item Tru-cut biopsy in cryptogenic organizing pneumonia(2015) Balcan, Baran; Olgun, Sehnaz; Sagmen, Seda Beyhan; Bagci Ceyhan, BerrinCryptogenic organizing pneumonia (COP) was first described by Davison and colleagues in 1983. Previously, it was called bronchiolitis obliterans organizing pneumonia (BOOB). The following are known causes of COP: toxic gas inhalation, chemotherapy, radiation therapy, aspiration, blood transfusion, upper respiratory tract infections, or it can be idiopathic. The clinical features of the patients resemble those of pneumonia or upper respiratory tract infection. In COP, imaging scans of the lungs reveal diffuse migrating patchy infiltrations which are in contact with the pleura. Corticosteroids are the first choice for treatment, but in some patients other immunosuppressive drugs are needed. Low doses may result in relapses. Transbronchial biopsy has a low yield in the diagnosis, instead tru-cut biopsy is the first choice for a definitive diagnosis. In this paper, we define our experience with two patients from whom we obtained a tru-cut lung biopsy in order to reach for a diagnosis.
