Mitotic chromosome analyses performed on 820 infertile men revealed 60 (7.3%) men with some kind of chromosomal abnormality. Sex chromosomal abnormalities were detected in 28 (3.4%) and autosomal translocations in 9 (1.0%). Pericentric inversions of chromosome 9, with possible adverse effect on reproduction, was found in 23 (2.8%). Chromosome variants comprised a group of 77 (9.3%) subjects. We suggest that men with severe oligozoospermia and azoospermia should be considered for cytogenetical evaluation. Copyright © 1984, Wiley Blackwell. All rights reserved

Aim: The aims of this study were to evaluate the health-related quality of life (HRQOL) and make the treatment decision less difficult. Methods: Between 2007 and 2009 radical retropubic prostatectomy (RRP) was performed in 96 patients and permanent prostate brachytherapy (PPB) in 88 patients at our hospital. The general and disease-specific HRQOL was measured using two instruments, the Medical Outcome Study 8-Item Short-Form Health Survey (SF-8) and the expanded prostate index composite (EPIC). Results: Comparing RRP and PPB, there were significant differences in all scores except for general health in the 1st month after treatment which had the same score in both groups. The baseline quality of life scores in physical function (p < 0.05), physical role (p < 0.01), social functioning (p < 0.01), emotional role (p < 0.01) and mental health (p < 0.01) showed significant differences between the group and were better in the PPB group than in the RRP group. The physical component summary score in the PPB group was better than in the RRP group in the 1st month (p < 0.01) but recovered up to 3 months in the RRP group. The urinary bother and irritative/obstructive scores in the 1st month were worse from baseline in both groups (p < 0.05) and remained significantly worse up to 6 months in the PPB group than in the RRP group where these scores recovered within3 months. The urinary incontinence score in the RRP group was still worse than in the PPB group up to 12 months (p < 0.01). Bowel function and bother were significantly better in the RRP group at 3 (p < 0.05) and 6 months (p < 0.01) than in the PPB group where bowel function at 12 months was worse than at baseline and in the RRP group. Sexual function (p < 0.01) and sexual bother were better in the PPB group and did not change until 12 months. Conclusion: The difference in disease-specific quality of life has become clearer using EPIC. As with other published studies, our results provide important information that will therefore be useful for selecting the optimal treatments for localized prostate cancer. Copyright © 2010 S.

Introduction/Aim. Glycosaminoglycans (GAG) are one of the main constituents of the connective tissue and cellular membrane. Their presence has been evidenced in mucosa and muscular tissue of the urinary bladder of both healthy individuals and those affected by carcinoma. This suggest their potential role in the onset of bladder carcinoma and follow-up of those patients. The aim of the study was to determine GAG levels in tumor tissue and the surrounding bladder mucosa in patients with bladder tumor, as well as in the bladder mucosa in patients with bladder carcinoma, and to compare the results according to the grade and stage of tumor and relapse. Methods. Tissue samples were taken in 61 patients (48 males and 13 females), mean age 61.5 years, range 40-92 years, obtained by transurethral resection (TUR) of bladder tumor, and 8 healthy persons. Determination of a total GAG content in the tissue samples was done by the Whiteman's method and then compared regarding the tumor grade and stage. Results. Tumor grade and stage directly correlated with the levels of GAG. The GAG levels were significantly higher in tumor samples as compared to healthy mucosa. Conclusion. Higher GAG levels were recorded in all the patients with bladder tumors comparing to smples obtained from healthy individuals. GAG levels do not predict tumor relapse.

Among 120 meiotic analyses of infertile men there were three cases with a particular meiotic anomaly: low chiasma count at diakinesis and spermatogenic arrest. All clinical findings, hormonal analyses and karyotypes from peripheral blood were normal. Meiotic studies showed that pachytene pairing was complete, but in diakinesis the mean number of chiasmata per cell was significantly lowered, chromosomes were fragmented and univalents could frequently be found. In all three cases azoospermia was the consequence of spermatogenic arrest, which occurred after diakinesis‐metaphase I. Copyright © 1982, Wiley Blackwell. All rights reserved

Meiotic studies were performed in two infertile male carriers of balanced reciprocal translocations between chromosomes 3;5 and 6;10. The first patient had severe oligozoospermia with all stages of meiosis present. The other patient was azzospermic with meiotic breakdown after the first meiotic division. A ring quadrivalent configuration was found in diakinesis in both cases. © 1984 Springer-Verlag.

Summary Objective Data pertaining to whether stress-induced aldosterone release is associated with cardiac disorders are lacking. This study was designed to compare whether the modulation of intra-operative aldosterone release by epidural analgesia had an effect on the brain natriuretic peptide (BNP) levels. Design, Patients, Measurements A study was pilot prospective, open label randomized one. Patients were randomized to one of two anaesthesia protocols: group 1 included 13 patients who received general anaesthesia, and group 2 included 12 patients who received combined general anaesthesia and epidural analgesia. Study protocol was by completed 25 male patients, median age 56 years, without significant comorbidities, who underwent radical cystectomy because of urinary bladder tumour. Serum aldosterone, BNP, cortisol (measured by radioimmunoassay), adrenocorticotropine hormone (ACTH) (by solid-phase ELSA), blood chemistry, complete blood count and vital signs were compared preoperatively, intra-operatively and at postoperative days (POD) 1 and 7. Results Hemodynamics was stable in both groups. Group 1 showed threefold serum aldosterone, (P = 0·001) 20-fold ACTH (P = 0·003) and twofold cortisol (P = 0·001) increases intra-operatively, unlike group 2. Both groups had a twofold BNP increase in POD 1 that remained above normal on POD 7 only in group 1 (P = 0·02; P = 0·019 vs group 2). Conclusion Alleviation of aldosterone release by epidural analgesia modulated the postoperative serum BNP pattern in patients with a low risk for cardiac diseases who underwent noncardiac surgery. © 2011 Blackwell Publishing Ltd.

A total of 326 infertile men, 126 with genitourinary tract injection, and 200 without infection, were compared with 60 fertile men. Seminal plasma antisperm antibody with other clinical and microbiologic investigations were performed in all. Infertile men with genitourinated tract infection had antisperm antibody in 11.9 percent, infertile men without infection in 14.5 percent, and fertile men in 5 percent; these differences were not significant. The most common causes of these infections were gram-negative organisms and Chlamydia. Comparison of the level of the titers of seminal plasma antisperm antibodies showed no significant difference between infertile and fertile men. This study shows no significant relationship between genitourinary tract infection and formation of the seminal antisperm antibody. © 1990.
