Publication Open Access Prevalence of poor sleep quality and its determinants among men suffering from erectile dysfunction(2023-09-01) ŞAHİN, BAHADIR; CİHAN A., KAZAZ İ. O., DURAN M. B., YILDIRIM Ö., BAŞER A., GÜL Ü., HASIRCI E., KIZILKAN Y., TURUNÇ T., ÇAM H. İ., et al.Objective: Recent findings implicate a higher prevalence of erectile dysfunction (ED) among men with sleep disorders. We investigated sleep quality among men with ED. Materials and Methods: A prospective study was conducted at 12 different andrology outpatient clinics among men with complaints of insufficient erections. The subjective quality of sleep was measured using the Pittsburgh Sleep Quality Inventory. Erectile function and its dimensions were measured using the International Index of Erectile Function (IIEF) questionnaire. The age-adjusted Charlson comorbidity index and Beck Depression Inventory were used to evaluate interrelations with comorbid disease severity and depression of the subjects consecutively in the study. Results: Among 431 eligible men, the median age of the participants and their erectile function scores in the IIEF were 51 [interquartile range (IQR)=43-59] and 16 (IQR=11-19), respectively. Poor sleep was observed in 192 of 431 (44.5%) subjects. Multivariable analysis revealed that younger age [odds ratio (OR)=0.95, p=0.01], lower body mass (OR=0.86, p=0.01), lower serum high-density lipoprotein cholesterol (OR=0.95, p=0.02), and higher severity of depression (OR=2.1, p=0.0001) were predictors of poor sleep quality among men with ED. Conclusion: Nearly half of the men with ED also suffer from poor sleep. Younger age, lean body mass, and severe depression were the main predictors of poor sleep quality among ED sufferers.Publication Metadata only Radikal prostatektomi patolojisinde gleason grade grubu yükselmesinin klinik önemi var mı?(2021-11-14) ŞAHİN, BAHADIR; DÖRÜCÜ, DOĞANCAN; ÇAM, HAYDAR KAMİL; ÖZGÜR G., TOPBAŞ F.

B., Greenfield A., Turan S., Bereket A., Güran T.Background: The human INHA gene encodes the inhibin subunit alpha protein, which is common to both inhibin A and B. The functional importance of inhibins in male sex development, sexual function, and reproduction remain largely unknown. Objective: We report for the first time two male siblings with homozygous INHA mutations. Methods: The medical files were examined for clinical, biochemical, and imaging data. Genetic analysis was performed using next-generation and Sanger sequencing methods. Results: Two brothers complained of gynecomastia, testicular pain, and had a history of hypospadias. Biochemistry revealed low serum testosterone, high gonadotropin and anti-Mullerian hormone, and very low/undetectable inhibin concentrations, where available. Both patients had azoospermia in the spermiogram. We have identified a homozygous 2 bp deletion (c.208_209delAG, R70Gfs*3) variant, which leads to a truncated INHA protein in both patients, and confirmed heterozygosity in the parents. The external genital development, pubertal onset and progression, reproductive functions, serum gonadotropins, and sex hormones of mother and father, who were heterozygous carriers of the identified mutation, were normal. Conclusion: Homozygosity for INHA mutations causes decreased prenatal and postnatal testosterone production and infertility in males, while the heterozygous female and male carriers of INHA mutations do not have any abnormality in sex development and reproduction.Publication Metadata only The effect of using a standard Illustrated consent form on anxiety levels in the urodynamic investigation: A prospective clinical study(2022-09-07) ŞAHİN, BAHADIR; ŞEKERCİ, ÇAĞRI AKIN; ONUR, AHMET RAHMİ; ÇAM, HAYDAR KAMİL; TARCAN, TUFAN; Özkan O., Güçtaş A.

F., SÖZEN T. S., ÖZEN A. H., AKDOĞAN B., ASLAN G., TÜRKERİ N. L., İZOL V., ŞAHİN B., et al.Objective: In this study, we investigated the correlation between prostate imaging reporting and data scoring system (PIRADS) grades of patients’ prostate lesions detected by multiparametric prostate magnetic resonance imaging (MpMRI) and prostate specific antigen (PSA) values obtained before prostate biopsy and its role in predicting clinically significant cancer in prostatectomy specimens. Materials and Methods: Patients who underwent biopsy and were diagnosed with prostate cancer (PCa) because of positive or negative MpMRI were evaluated. Histopathological factors were recorded, and the relationship between the PIRADS grading system and PSA values was analyzed in patients who underwent radical prostatectomy and preoperative MpMRI. PSA cut-off values predicting clinically significant PCa (CSPCa) in MpMRI were calculated. Results: A total of 1,319 patients were included in the study. MR-fusion biopsy was performed in 58% of the patients, and malignant histopathology was detected in 49% of the patients. While 87% of the patients had CSPCa, 13% had clinically insignificant PCa. The sensitivity and specificity of the PSA 4 ng/mL cut-off value were 88.6% and 15.1% in all patient groups, respectively. In predicting CSPCa, sensitivity was 88.9% and specificity was 18.8% for PSA 4 ng/mL cut-off value in MpMRI-negative patients. If PSA >4 ng/mL in MpMRI-negative patients, there is a >45% PCa detection rate in biopsy, but biopsy is more appropriate for PSA >10 ng/mL for CSPCa. In MpMRI-positive patients, if PSA is >2.5 ng/mL, biopsy provides a >50% PCa and >30% CSPCa diagnosis. If there are PIRADS 5 lesions and PSA is >2.5 ng/mL, biopsy has a >70% PCa and >60% CSPCa detection rate. Conclusions: It may be appropriate to consider higher PSA cut-off values (PSA >10 ng/mL) to make a biopsy decision in patients with negative MpMRI, whereas it may be possible to detect CSPCa at lower PSA values in patients with positive MpMRI findings and high PIRADS grade.Publication Metadata only Miyelomeningoselli hastalarda nörojenik detrusor aşırı aktivitesine bağlı vezikoüreteral reflünün tedavisinde İntravezikal onabotulinum toksin a enjeksiyonunun etkinliğI(2013-10-06) TARCAN, TUFAN; ŞAHİN, BAHADIR; ALPAY, HARİKA; ŞİMŞEK, FERRUH; TARCAN T., AKBAL C., Top T., ŞAHİN B., Asutay M.
