Bazex Syndrome: Acrokeratosis Paraneoplastica in Association With Simultaneous Multiple Genitourinary Tumors
(Elsevier Inc., 2000) Atilla, M.K.; Yilmaz, Y.; Bekerecioglu, M.; Akpolat, N.; Kösem, M.; Aydin, S.
We report a patient with Bazex (Bazex-Dupre-Christol) syndrome in association with multifocal basal cell carcinoma, epidermoid carcinoma of the lung, adenocarcinoma of the prostate, and possibly undifferentiated carcinoma of the bladder. To our knowledge, this is the first report of a patient with Bazex syndrome that consisted of four tumors, including two genitourinary tumors. (C) 2000 Elsevier Science Inc.
Can Ldh Activity in Spermatic Vein Indicate Testicular Damage? a Preliminary Report
(Akademiai Kiado Rt., 1998) Odabaş, Ö.; Yilmaz, Y.; Atilla, M.K.; Tarakçioǧlu, M.; Aydin, S.
We aimed to investigate the relationship between varicocele and lactic dehydrogenase (LDH), an intracellular enzyme that indicates cellular damage. LDH levels were measured in the blood samples of 17 oligoasthenospermic infertile patients with varicocele which were obtained synchronously from spermatic and peripheral veins during operation. Sperm counts ranged from 1 to 74 million/ml, while motility ranged from 10% to 60%. LDH level in spermatic vein was found statistically higher than the level in peripheral vein (p= 0.042). There was no correlation between sperm counts and LDH level in spermatic vein. We found a significant increase in spermatic vein LDH level in varicocele. We think that further studies are needed to reveal the relationship between spermatic vein LDH level and varicocele.
Enuresis
(1998) Aydin, S.; Atilla, M.K.
There has been no clear definition for enuresis although it has been accepted as bed-wetting. Nocturnal enuresis which is the most common type, means bed-wetting during sleep. Approximately 1-2 % of the children continues to be enuretic at puberty. Etiologic studies reveal genetic, organic, social and psychologic causes. Since there have been no clear etiologic factors therapeutical approaches are a lot in number such as, supportive education therapy, psychotherapy, behavioural, hypnotherapy and drug therapy. Anticholinergics, desmopressin, imipramin and piracetam are used in pharmacotherapy.
Evaluation of 42 Patients With Chronic Abacterial Prostatitis: Are There Any Underlying Correctable Pathologies
(Akademiai Kiado Rt., 1998) Atilla, M.K.; Sargin, H.; Odabaş, Ö.; Yilmaz, Y.; Aydin, S.
Forty-two young men with abacterial prostatitis underwent physical examination, semen analyses, rectal US (TRUS) and magnetic resonance imaging (MRI) of the pelvis. Findings on TRUS showed no distinct differences like capsular irregularity, dilatation of the seminal vesicles and calcified foci in the prostate. In MRI pathologic conditions were noted as transitional zone cysts, prostatic utricle cysts and abscesses of the seminal vesicles. MRI had been found superior to TRUS in imaging the prostate and to predict associated pathologic conditions. It is also concluded that some additional factors as a cause of prostatitis must be determined in patients with chronic abacterial prostatitis.
Experimental Testicular Torsion and Its Effects on the Contralateral Testicle
(1997) Aydin, S.; Uǧraş, S.; Odabaş, Ö.; Yilmaz, Y.; Atilla, M.K.; Yeǧin, E.
Objective: Following experimental unilateral torsion of the testis the histologic effects of unilateral testicular torsion on the contralateral testis were investigated. Materials and methods: Utilizing detorsion or orchiectomy at 4 hours and 8 hours after torsion, the effects of early and late treatment modalities on the contralateral testicle were observed. Results: Morphometry of the contralateral testis revealed some alterations including focal sclerosis, decrease in mean seminiferous tubular diameter and a marked increase of the Leydig cells in some subgroups. Conclusion: In spite of some changes, definite evidence for contralateral damage due to ipsilateral torsion contributing to male infertility was hardly observed.
Failure of Artificial Insemination of Husband's Semen in the Treatment of Male Infertility
(Kluwer Academic Publishers, 1996) Aydin, S.; Inci, O.; Alagöl, B.; Hüseyin, I.; Kaya, E.; Dellaloǧlu, G.
In the management of infertility, in case semen quality is found insufficient and could not be improved by medical means, handling the available spermatozoa in the most beneficial way has been aimed. Thus, artificial insemination with low quality semen has become a therapeutic alternative. In this study homologous artificial insemination has been used to treat infertility caused by oligoasthenospermia. Eighteen couples have been treated for 58 cycles by intrauterine or paracervical insemination using cervical cups. During the same period 42 cycles with timed vaginal intercourse have been assessed. Though no pregnancies could be obtained following artificial insemination, one pregnancy occurred during no-treatment cycles.
Fibroepithelial Polyp of the Ureter Associated With an Adjacent Ureteral Calculus
(1997) Uǧras, S.; Odabaş, Ǒ.; Aydin, S.; Yilmaz, Y.
Ureteral fibroepithelial polyps are rare benign tumours. Sometimes an ureteric calculus may be seen, proximal to the polyp. We describe a case of fibroepithelial polyp (FEP) associated with a calculus in the distal part of the right ureter. To our knowledge this is the first ureteral FEP reported in the literature associated with a ureteral calculus distal to it. Aetiology, clinical features, diagnosis and therapy of fibroepithelial polyps are discussed in the light of the literature.
Multicentral Clinical Evaluation of the Aetiology of Erectile Dysfunction: a Survey Report
(2001) Aydin, S.; Ünal, D.; Erol, H.; Karaman, I.; YIlmaz, Y.; Ş, E.; BayraklI, H.
Patients with erectile dysfunction, who admitted to 4 different urological centres in Turkey were evaluated in terms of aetiological factors to establish the aetiology of erectile dysfunction in our population and compare it with the data derived from Western communities. After the history, physical examination, psychological evaluation and laboratory testing, a clinical diagnosis was established as primarily psychogenic, organic, or mixed aetiology. Mean patient age was 43.5 years (range 17 to 69), and 9 of the patients were unmarried. Of the patients 53 had vascular risk factors, and 10 reported a history of alcohol abuse. Eleven patients were using drugs that might interfere with the disorder. In this multicentral study of 115 impotent men, an organic cause was found in 43%, psychogenic in 47%, and mixed in 19%. Mean age of the overall patients was 43.48. When the ages of the patients with organic erectile dysfunction and those with psychogenic erectile dysfunction were compared, it was clearly seen that those with organic erectile dysfunction were much older (52.73 versus 33.02).
On the Level of Academic Achievement of the Vocational School Students: the Effect of Motivation
(Sakarya University, 2017) Aydin, S.; Genel, Y.; Kahraman, K.; Tola, Y.; Of, M.; Mutlu, C.
Motivation, a positive effect that directs behavior toward a goal could be perceived as one of the most important psychological concepts in all area of the life especially in education. In this study, it was investigated the relationship between academic achievement and motivation of vocational school students according to gender and class parameters. 192 vocational school students from 4 different programs (accounting, business, chemistry, and construction) attended the Academic Motivation Scale (AMS) which was prepared by Vallerend (1992). The AMS consisted of 28 Likert-type scale questions related to intrinsic motivation, extrinsic motivation and amotivation. Findings of the study indicated that there was only one significant relationship that was between academic achievement and two intrinsic motivation subscales. Females had higher scores in all motivation types. Also, there was only significant differences between males and females for intrinsic motivation. And, according to departments, there was significant difference in motivation by department in extrinsic motivation. © The Turkish Online Journal of Educational Technology.
Primary Non-Mucinous, Non-Papillary Adenocarcinoma of the Ureter
(Akademiai Kiado Rt., 1998) Yilmaz, Y.; Dilek, H.; Odabaş, Ö.; Atilla, M.K.; Aydin, S.
We report a case of primary, non-mucinous, non-papillary ureteral poorly differentiated adenocarcinoma. The primary focus could only be detected during surgical exploration, because computed tomography (CT), ultrasonography (US), intravenous urography (IVU) and other radiologic and endoscopic procedures revealed no primary neoplastic focus, only lymph node and various bone metastases. Total nephroureterectomy with a bladder cuff was performed to decrease pain of the patient and to remove the primary tumoral focus.
The Role of Power Doppler Ultrasonography in the Diagnosis of Prostate Cancer: a Preliminary Study
(1998) Sakarya, M.E.; Arslan, H.; Unal, O.; Atilla, M.K.; Aydin, S.
Objective. To determine the role of transrectal power Doppler ultrasonography (PDU) in the diagnosis of prostate cancer. Patients and methods. Thirty-six patients (mean age 66.4 years, SD 7.7, range 59-82) with possible prostate cancer, suspected from an abnormal digital rectal examination or elevated prostate specific antigen level, underwent transrectal ultrasonography, transrectal PDU and biopsy. The vascularity on PDU was graded on a scale of 0-2, where grade 1-2 was considered positive and grade 0 negative. Results. The vascularity was grade 2 in 11 patients, grade 1 in 11 and grade 0 in 14; 20 of the 36 (56%) patients had prostate cancer. Of the 22 patients positive on PDU, 18 had malignant disease and four benign; two of 20 patients with histopathologically confirmed malignancy had a normal PDU. The sensitivity of PDU was 90%, the specificity 75% and the positive predictive value 82%, Conclusion. Focal hypervascularity on PDU was associated with an increased likelihood of prostate cancer. Although ultrasonography alone cannot detect all cancers, even using PDU, the technique appears to increase the sensitivity and to help identify appropriate sites for biopsy.
Testicular Needle Biopsy: Is It a Safe and Adequate Method
(1997) Odabaş, Ö.; Uǧraş, S.; Yilmaz, Y.; Aydin, S.; Atilla, M.K.
We aimed to investigate if testicular needle biopsy is adequate and safe for the examination of testis. Needle biopsies were performed on 21 testes of 5 patients with advanced prostate cancer and 11 patients with cryptorchidism before orchiectomy. Biopsies were done with the prostatic tru-cut needle. After needle biopsy, the tract and puncture sites were explored and an incisional biopsy was performed on each testis. Both needle specimens and open biopsy specimens were fixed in Bouin's solution and sent for histologic examination. There were small haematomas in two testes and moderate heamorrhage between tunica vaginalis layers in another. The tissues obtained by needle biopsy were sufficient except for two specimens and diagnostic accuracy was perfect. Nevertheless, measurement of the seminiferous tubules of the lamina propria could not be achieved in many cases.
Using of Nmp 22 Only or Together With the Cytology in the Diagnosis and Follow-Up of Bladder Tumors
(2003) Yilmaz, Y.; Aydin, S.; Bayrakli, H.; Uǧraş, S.; Özman, E.; Berktaş, M.
Introduction: Nuclear Matrix Protein is a tumor marker using for early diagnosis and follow up of bladder cancer. This study was designed to determine the effectiveness of NMP 22 and cytology for early detection and follow up of bladder cancer. Material and Methods: Sixty-eight patients who were included in this study were divided in three groups. The first group comprised 46 patients with hematuria and lower urinary tract symptoms, who had no previous history of bladder cancer. Seventeen patients were included in the second group who treated by transurethral resection of bladder tumor, partial cystectomy or intracaviter chemotherapy. The third group consisted of 5 patients with bladder tumor previously. They refused any kind of treatment. A reference value of 15 U/ml was utilized for NMP 22 in urine. A positive outcome was a tumor seen in cystoscopic examination, which was later histopathologically confirmed as malignant. A negative outcome was tumor free cystoscopy, or benign histopathology of the suspected biopsy specimens. Urine cytology results were considered "malign" (severe dysplasia, malign and transitional cell carcinoma) and "benign" (metaplasia, inflamatory cells, dysplasia ). Results: Eighteen patients of the first group had bladder cancer, whereas NMP 22 was (+) in 29 patients in this group. However, NMP was (+) in 14 of the 18 patients with bladder tumor. The sensitivity and specificity of NMP 22 in group 1 were 77.7% and 46.6%, and that of cytology were 83.3% and 89.2% respectively. When all of the patients were evaluated together, the sensitivity and specificity of NMP 22 were 80.7% and 64.2%, and that of cytology were 88.4% and 90.4% respectively. Conclusion: In conclusion, this study indicates that NMP 22 reduces the necessity of cystoscopy, and it can be used as a screening test in combination with cytology.
