The value of prostatic acid phosphatase and prostate specific antigen as serum markers in carcinoma of the prostate.

The value of prostatic acid phosphatase (PAP) and prostate specific antigen (PSA) as serum markers in carcinoma of the prostate (CaP) was investigated in this study. A group of 75 patients entered this trial, 25 with CaP, 25 with benign prostatic hyperplasia (BPH) and 25 with urologic disorders other than prostatic diseases. In the CaP group, PAP was above normal levels in 48% of the patients and PSA in 92%. In the BPH group these rates were 20% and 72%, respectively. No elevation was detected in the third group. In CaP patients with capsular invasion, PAP and PSA levels were above normal in 25 and 87.5%. In metastatic carcinoma, PAP was high in 75% and PSA in 100%. Our study reveals that neither of these markers is useful in the initial diagnosis of CaP. Though PSA seems to be more sensitive, it is not more specific than PAP.

Single dose of ofloxacin treatment in women with dysuria and frequency.

The efficacy of single dose ofloxacin in lower urinary tract infections was investigated in this study. Fifty-one women with complaints of dysuria and frequency were treated with a single dose of 400 mg ofloxacin orally. The results of urinalysis and urine culture which were performed 4-7 days after the administration of the drug were evaluated. Thirty-eight of the 47 evaluable patients (80.85%) were asymptomatic with normal urinalysis and sterile urine, thus cured. The data of the study suggest that single dose ofloxacin may be the first treatment option in the particular group of women with uncomplicated urinary tract infection.

Neoadjuvant (induction) chemotherapy in advanced bladder carcinoma.

Traditional approaches for the treatment of locally advanced bladder tumours may not be sufficient enough. Neoadjuvant chemotherapy, a new modality, may be beneficial by enhancing the local and systemic control of the disease. The background of this new modality and early results of various trials are discussed.

The cost and availability of therapeutic options in advanced prostatic carcinoma in Turkey.

Advanced prostatic carcinoma may be treated by a variety of methods of endocrine manipulation which affect the production of androgens. This can either be done by bilateral orchiectomy or by a number of drugs. Orchiectomy has two advantages: low cost and being a once-only procedure. This report outlines the costs of various methods of hormonal treatment and compares them with each other in Turkey.

Transurethral ultrasonography, fiberoptic cystoscopy and bladder washout cytology in the evaluation of bladder tumours.

The impact of transurethral ultrasonography, fiberoptic cystoscopy and bladder washout cytology on assessment of bladder tumours was investigated in this study. Transurethral ultrasonography had an accuracy rate of 96.5% in diagnosing and staging bladder tumours. The accuracy rates of fiberoptic cystoscopy and washout cytology were 90.9% and 73.7%, respectively, in diagnosis. The efficacy of transurethral ultrasonography was found to be high enough for routine employment in the evaluation of the bladder tumours. Fiberoptic cystoscopy in conjunction with washout cytology as a combination relatively easy to perform can be used especially for follow-up purposes of the bladder tumours.

Efficacy of prophylactic gentamicin use in postoperative urinary tract infections after endoscopic procedures of the urinary tract.

In this study, the efficacy of prophylactic antibiotic use was investigated. A total of 110 patients undergoing endoscopic procedures of the urinary tract were enrolled in the study. Fifty-five of the patients were treated with 8-hourly, 80 mg gentamicin sulfate of total three doses. The drug administration began just prior to the operation. Seven postoperative infections (12.7%) were detected, the same number as in the control group of 55 patients. The results confirm that there is no place for gentamicin prophylaxis in endoscopic procedures of the urinary tract.

The impact of squamous metaplasia in transitional cell carcinoma of the bladder.

The authors report a case of squamous cell carcinoma of the bladder induced by radiation therapy for transitional cell carcinoma, possibly from sites of squamous metaplasia, which were present at the time of initial diagnosis. Although data in the literature are not sufficient at the moment in terms of implication on prognosis, foci of squamous metaplasia during the initial diagnosis of transitional cell carcinoma must be carefully sought and their presence warrants caution in utilizing irradiation in the management of the disease.

Serum and urine levels of tumour necrosis factor in patients with genitourinary cancer and their relevance to disease status.

Serum and urine levels of tumour necrosis factor (TNF) which is a lymphokine was measured in patients with genitourinary cancer (either prostatic, bladder or testicular carcinoma) in order to find out whether there were elevated levels of TNF in those patients and if it was related to disease status. Although the preliminary results are not conclusive, further research on TNF may prove this immunoprotein to be a potential diagnostic and therapeutic agent.

Current approaches in the treatment of bladder cancer and policy in Marmara University Hospital.

Bladder cancer is one of the malignancies encountered frequently in urologica practice. Since the three main treatment modalities (surgery, chemotherapy and radiotherapy) may be used alone or together, there are many treatment options. In this paper the current approaches in the treatment of bladder tumours are reviewed and the policy in Marmara University Hospital is described.

Ectopic production of human chorionic gonadotropin in transitional cell carcinoma of the bladder. An immunohistochemical study.

A retrospective histopathological and clinical analysis of 43 patients with transitional cell carcinoma of the bladder, attending our institution between March 1986 and April 1989, was performed. The indirect immunoperoxidase method was used for the demonstration of human chorionic gonadotropin production in transitional cell carcinoma cells. Nine of the 16 grade III tumors stained positive for human chorionic gonadotropin, while grade I and grade II tumors remained unstained. Our results suggest that the presence of human chorionic gonadotropin in tumor cells is a strong evidence of dedifferentiation, and its association with patient prognosis needs further investigation, especially in high-grade, low-stage tumors.

Epidemiological case-control study on the etiology of bladder cancer in Turkey.

A case-control study of 194 patients with bladder cancer and the same number of age- and sex-matched hospital controls were interviewed to estimate the role of various factors on the etiology of bladder cancer in Turkey. There was a significant difference between the case and control groups on cigarette smoking (p less than 0.001), alcohol intake (p less than 0.001), Turkish coffee consumption (p = 0.01), and artificial sweeteners (p less than 0.05). The risks for alcohol and tobacco users increased in correlation with the duration of exposure. The risk of bladder cancer increased directly with the quantity and frequency of alcohol intake. Alcohol and coffee drinking was found to be a promoting factor when adjusted to smoking habits (p less than 0.05). No statistical comparisons could be made to clarify the risks attributed by occupation and place of residence due to small figures in each group. However, in farmers, there was a significant difference between the cases and controls on the use of artificial fertilizers and insecticides (p less than 0.01). People who were exposed to unspecified chemical substances were more prone to develop bladder cancer (p less than 0.001). We conclude that both personal habits and exogenous carcinogens play a role in the etiology of bladder tumors.

Present status of undergraduate urological education in Turkey: is standardization necessary?

23 medical faculties exist in Turkey at the moment and 2 others are being established. Considering that all these faculties run their own programs independently, different education systems might effect the standard of doctors and health care. All of the new graduates in this country face a centralized examination for postgraduate posts in teaching hospitals or start an obligatory service under the authority of the Ministry of Health and Social Welfare. This necessitates standardization in medical education to provide equal facilities and opportunities to all young doctors. Questionnaires, replied to by the urology departments of medical faculties, reflect a wide range of teaching periods in urology with a broad spectrum of topics. Under these circumstances it is advisory to agree on both the time period and content of a standard urology program, as well as other subjects, for better health care and equal chances in centralized examinations.
