ABSTRACT

Aging in the male is accompanied by steroid hormonal decline, and men may develop symptoms associated with hypogonadism. Increased awareness of 'andropause' in recent years has led to greater demand for hormonal assessments, resulting in a rising burden for health economics. We conducted a cross-sectional study to define men at risk for hypogonadism, in whom further hormonal investigation should be performed. We examined 664 blue-collar workers aged 40-60 years at their workplace and determined hormonal status and body mass index (BMI). Men with an abnormal urogenital status and those on medication that might affect endocrine status were excluded from the study. All participants completed the validated Aging Male Symptom (AMS) questionnaire and obtained scores for psychological symptoms, somatovegetative symptoms, and sexual symptoms. Multiple logistic regression analyses revealed a significantly increased risk (represented by the odds ratio) of psychological symptoms for men with low levels of testosterone and/or bioavailable testosterone (BAT). Increased BMI as well as low testosterone levels and/or low BAT levels raised the risk of somatovegetative symptoms. Each decrease of BAT by 1 ng/ml caused an approximately 1.8-fold increase of the risk (odds ratio = 1.832, p = 0.005). Additional independent risk factors were increased age and low luteinizing hormone (LH) level. Men aged 55 years with BMI > 28 kg/m2 and with somatovegetative symptoms and moderate or severe psychological symptoms had a 7.2-fold increase in the risk of a BAT level < 1.5 ng/ml compared to men without these risk factors (p < 0.001). Sensitivity and specificity were 75% and 71%, respectively. The AMS score combined with age and BMI provides an easy and convenient method to identify men with probable androgen deficiency who require hormonal assessment.

ABSTRACT

In 1994 the Massachusetts Male Aging Study described an inverse correlation of the serum levels of dehydroepiandrosterone sulfate (DHEAS) and the incidence of erectile dysfunction (ED). The positive results of a pilot study in the treatment in patients with no organic etiology prompted a detailed investigation on the efficacy of DHEA therapy for ED in patients with different organic etiologies, in a prospective study. The inclusion criteria included ED, a normal physical condition, normal serum levels of testosterone, prolactin and PSA and a serum DHEAS level < 1.5 micromol/l. The study patients comprised 27 patients (group 1) with hypertension, 24 patients (group 2) with diabetes mellitus, six patients with neurological disorders (group 3) and 28 patients (group 4) with no organic etiology were treated with 50 mg DHEA p.o. for 6 months. We assessed efficacy by using the responses to question 3 (frequency of penetration) and question 4 (maintenance of erections after penetration) of the 15-question International Index of Erectile Function (IIEF). DHEA treatment was associated with statistically significantly higher mean scores compared to baseline values for question 3 and question 4 of the IIEF in groups 1 and 4 after a period of 24 weeks. The differences between the mean scores of groups 2 and 3 and the baseline values were not statistically significant. Our results suggest that oral DHEA-treatment may be of benefit to patients with ED who have hypertension or to patients with ED without organic etiology. There was no impact of DHEA therapy on patients with diabetes mellitus or with neurological disorders.

ABSTRACT

Erectile dysfunction is a common problem, especially among older men. It is often caused by psychological problems, and is also the reason for pronounced impairment of psychosocial well-being. Many systemic diseases, genitourinary surgery, drugs, particularly antihypertensive and psychotropic drugs, and also chemotherapeutic agents and dexamethasone are attributed as being causes of erectile dysfunction. In our case, severe erectile dysfunction was present for 8 months before non-small cell lung cancer was diagnosed. Normal sexual function, observed for a short period immediately following chemotherapy, is a highly unusual finding and has not been published before. Chemotherapeutic agents have repeatedly been shown to result in cessation of sexual function including erection. While we cannot offer a definite explanation for our findings, undefined paraneoplastic processes leading to erectile dysfunction amenable to successful cytotoxic intervention could be a possible explanation for our observation.

ABSTRACT

PURPOSE: The objective of this retrospective study is to show the importance of sonography in andrological patients with testicular microlithiasis (TM). PATIENTS AND METHODS: 1314 male patients were seen to our andrological clinic in the course of one year. The age range of these patients was 25 to 39 years (mean age 32 years). All patients underwent testicular sonography as well as a sperm-analysis. RESULTS: 284 patients showed normozoospermia without any evidence of TM. Of the remaining 1030 patients with a pathological spermiogram, 8 were shown to display more than 10 echogenic foci per transducer field in both tests. 1 patient suffering from an already palpable testicular tumor only showed, unilateral, unifocal calcification. Another patient who had suffered from a maldescensus testicle in his early childhood discharged only one unifocal calcification. Tumor markers including AFP and beta-HCG were normal in 9 patients, but elevated in 1 patient suffering from a testicular tumor (AFP: 73 kU/l; beta-HCG: 10.6 U/l). The hormonal status was normal in 6 patients and pathological 4 patients with the diagnosis of OAT-syndrome. CONCLUSION: TM is a rare condition even in andrological patients. Nevertheless, a thorough scrotal sonography is mandatory in order to rule out testicular malignancy.

ABSTRACT

von Recklinghausen neurofibromatosis is an autosomal dominant transmitted disease with 100% penetrance but variable phenotypic expression. The incidence of this systemic disease is 1 in 3000 live births; however, genitourinary manifestations are rare. We report on our management of 1 case during the past 16 years.

ABSTRACT

PURPOSE: During the past 30 years, radiation therapy with 28 to 30 Gy for para-aortic and ipsilateral iliac node areas was the standard adjuvant treatment for clinical stage I seminoma after orchiectomy. However, late effects of radiotherapy prompted a search for alternative adjuvant treatment approaches, including surveillance and application of carboplatin. In this retrospective analysis, we evaluated the efficacy and toxicity of two adjuvant single-agent carboplatin courses in 107 patients who were diagnosed with clinical stage I seminoma at our study centers between 1988 and 1999. PATIENTS AND METHODS: All 107 patients (median age, 39 years; range, 24 to 63 years) received two postoperative adjuvant cycles of carboplatin (400 mg/m(2)). The pathologic tumor stage was pT1 in 84 patients, pT2 in 18 patients, and pT3 in five patients. Whole blood count and serum chemistry were evaluated weekly during treatment to assess hematologic and nonhematologic toxicity. RESULTS: Six patients died from tumor-unrelated causes. The remaining 101 patients are currently alive and free of disease after a median follow-up of 74 months (range, 5 to 145 months). A detailed analysis of hematologic toxicity showed only World Health Organization (WHO) grade 1 leukocytopenia in 10.7% of all cycles and WHO grade 2 leukocytopenia in 2.1% of all cycles. CONCLUSION: Regarding the absence of tumor recurrences in our retrospective analysis and the favorable toxicity profile with no episodes of long-term toxicity, we suggest that two adjuvant courses of single-agent carboplatin for clinical stage I seminoma patients might be equivalent to radiotherapy.

ABSTRACT

BACKGROUND: The known importance of the endocrine system, particularly of steroid hormones, for development of the prostate gland and the fact that steroid hormones act as immunmodulators prompted us to compare hypophyseal, adrenal, and gonadal hormones, including cortisol, in patients with benign and malignant prostatic diseases. METHODS: Patients with newly diagnosed, untreated prostate cancer (PC) (n = 75) and, as a control population, those with untreated lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH) (n = 159) entered this prospective study. In all patients, the following parameters were obtained by serum analysis: prostate-specific antigen (PSA), human luteinizing hormone (hLH), human follicle-stimulating hormone (hFSH), testosterone, estradiol (E2), cortisol, and dehydroepiandrosterone-sulphate (DHEA-S). Serum samples were collected of fasting patients between 7. 30-10.00 AM. RESULTS: Age was comparable in both groups (PC: 65.6 +/- 7.6 years (mean +/- standard deviation) vs. controls: 64.9 +/- 8. 1 years; P = 0.56). HFSH (PC: 6.6 +/- 3.9 mIU/ml; controls: 8.4 +/- 6.4 mIU/ml; P = 0.04), hLH (PC: 5.3 +/- 4.8mIU/ml; controls: 7.6 +/- 6.2 mIU/ml; P = 0.009), and estradiol (PC: 25.8 +/- 12.7 pg/ml; controls: 32.6 +/- 12.6 pg/ml; P = 0.0003) were significantly lower in PC patients than controls. Cortisol (PC: 16.7 +/- 4.2 microg/dl; controls: 13.5 +/- 4.3 microg/dl; P < 0.0001) was significantly higher in cases. The difference for cortisol and estradiol concentrations between PC patients and controls held true in all life-decades. Serum concentrations for DHEA-S and testosterone were comparable between PC and control patients. In PC patients, none of the endocrine parameters correlated to serum PSA or clinical/pathological stage. CONCLUSIONS: Patients with newly diagnosed, untreated PC yielded significantly higher cortisol and lower estradiol serum concentrations than controls. The known effect of cortisol on the immune status warrants further studies.

ABSTRACT

OBJECTIVES: In 1994, the Massachusetts Male Aging Study presented the finding of an inverse correlation of the serum levels of dehydroepiandrosterone sulfate (DHEAS) and the incidence of erectile dysfunction (ED). Prompted by the positive results of a pilot study on the treatment of ED with dehydroepiandrosterone (DHEA), we performed a detailed investigation on the serum DHEAS levels in men with ED according to age category. METHODS: Inclusion criteria included a history of ED for more than 6 months, a body mass index less than 30, and a state of good general health. Serum DHEAS concentrations were determined in 309 patients with ED and 133 healthy volunteers. All participants were carefully screened to assess medical factors known or suspected to alter endocrine function. Questions 3 and 4 of the International Index of Erectile Function were used to evaluate erectile function. RESULTS: The mean serum levels of DHEAS in patients with ED were lower than in healthy volunteers until 60 years of age. The shape of the curve of the patients with ED indicated a quadratic decrease of DHEAS with age in contrast to a more linear decrease of DHEAS with age in the control group. CONCLUSIONS: Our results suggest that until the age of 60 years, the mean serum level of DHEAS is lower in patients with ED than in healthy volunteers.

ABSTRACT

BACKGROUND AND AIM OF STUDY: Pre-emptive analgesia represents a treatment strategy which tries to prevent the development of pain by inhibiting central reactions to peripheral sensory stimuli. In a prospective randomized double-blind placebo-controlled study, the effect of oral premedication with 4 mg of a slow-release hydromorphone preparation on postoperative piritramide consumption and subjective pain perception is being evaluated. PATIENTS AND METHODS: 96 women undergoing hysterectomy were randomly assigned to four study groups. Patients from groups 1 and 2 received hydromorphone and placebo respectively two hours before surgery, while those from groups 3 and 4 were given the same substances one hour after the end of the operation. Postoperative pain relief was provided by a patient-controlled infusion pump with piritramide. The intensity of postoperative pain as perceived by the patients was quantified on a visual analogue scale. Piritramide consumption and pain scores were recorded at 1 and 24 hours after surgery. Approval of the local Ethics Committee had been obtained beforehand as well as written informed consent from the patients. RESULTS: No significant differences in piritramide consumption were observed in between the four study groups. Visual analogue scale (VAS) ratings at 1 and 24 hours after surgery did not show any significant differences either--irrespective of whether the patients had received hydromorphone or placebo preoperatively or postoperatively. CONCLUSION: In our study, oral administration of 4 mg of slow-release hydromorphone did not show any greater pre-emptive analgesic effect than placebo.

ABSTRACT

OBJECTIVE: The aim of this study was to determine the relevance of urinary extravasation as proven by cystogram 18 days after radical retropubic prostatectomy for the degree of postoperative urinary incontinence and the incidence of anastomotic strictures. PATIENTS AND METHODS: A total of 225 patients underwent radical retropubic prostatectomy at our institution during a 30-month period, 215 of whom received a cystogram a mean 18 days following surgery. Three and 6 months after surgery these 215 patients were evaluated regarding the degree of urinary incontinence and the presence of anastomotic strictures. RESULTS: The cystogram demonstrated a watertight anastomosis in 89% (n = 195; group I), the remaining 11% (n = 24; group II) showed urine extravasation. Groups I and II were comparable with respect to age, preoperative serum levels of prostate-specific antigen (PSA), tumor grade and pathological staging. Six months after surgery, there was no statistically significant (p > 0.05) difference between both groups regarding the degree of urinary incontinence and the presence of anastomotic strictures. CONCLUSIONS: The presence of urine extravasation 18 days after radical retropubic prostatectomy has no impact on postoperative urinary incontinence and the incidence of anastomotic strictures. Based on these data it is not indicated to leave the catheter in situ beyond that point of time.

ABSTRACT

PURPOSE: Indinavir was approved by the Food and Drug Administration in 1996 as a human immunodeficiency type 1 protease inhibitor to treat human immunodeficiency virus infection. Prompted by the high number of patients receiving indinavir who present with renal colic at our institution, we performed a detailed investigation of the true frequency of urolithiasis during indinavir treatment. MATERIALS AND METHODS: We evaluated 105 patients with a mean age of 38.1 years who were treated with indinavir from 1996 to 1997. Before indinavir treatment was initiated all patients underwent renal ultrasonography, urinalysis, and determination of serum sodium, potassium, calcium, uric acid and creatinine. It was recommended that all patients drink 2 l of fluids daily, and all remained under continuous surveillance. RESULTS: Metabolic evaluation and ultrasonography showed no abnormality in any case. A stone episode occurred in 13 men (12.4%) as renal colic during observation. Colic recurred in 1 patient after 2 and 5 months, and in 1 after 2 months. Median duration of indinavir treatment until an acute stone episode was 21.5 weeks (range 6 to 50). A total of 12 stones passed spontaneously. Three patients underwent ureteroscopic calculous removal and 1 was treated with extracorporeal shock wave lithotripsy. CONCLUSIONS: Despite adequate patient information and compliance the rate of nephrolithiasis during indinavir therapy was 12.4%.

ABSTRACT

OBJECTIVES: In 1994, the Massachusetts Male Aging Study presented an inverse correlation of the serum levels of dehydroepiandrosterone (DHEA) and the incidence of erectile dysfunction (ED). We evaluated the efficacy of DHEA replacement in the treatment of ED in a prospective, double-blind, randomized, placebo-controlled study. METHODS: The inclusion criteria included ED, normal physical and neurologic examinations, serum levels of testosterone, dihydrotestosterone, prolactin, and prostate-specific antigen (PSA) within the normal range, and a serum DHEA sulfate level below 1.5 micromol/L. Also all patients had a full erection after a pharmacologic erection test with 10O microg prostaglandin E1; pharmacocavernosography showed no visualization in corporeal venous structures. Forty patients from our impotence clinic were recruited and randomly divided into two groups of 20 patients each. Group 1 was treated with an oral dose of 50 mg DHEA and group 2 with a placebo one time a day for 6 months. The International Index of Erectile Function (IIEF), a 15-item questionnaire, was used to rate the success of this therapy. RESULTS: Therapy response was defined as the ability to achieve or maintain an erection sufficient for satisfactory sexual performance according to the National Institutes of Health Consensus Development Panel on Impotence. DHEA treatment was associated with higher mean scores for all five domains of the IIEF. There was no impact of DHEA treatment on the mean serum levels of PSA, prolactin, testosterone, the mean prostate volume, and the mean postvoid residual urine volume. CONCLUSIONS: Our results suggest that oral DHEA treatment may be of benefit in the treatment of ED. Although our patient data base is too small to do relevant statistical analysis, we believe that our data show a biologically obvious trend that justifies further extended studies.

ABSTRACT

We evaluated the efficacy of dehydroepiandrosterone substitution in elderly men with erectile dysfunction. Fifty patients were randomly divided into two groups of 25 patients each. Group 1 was treated with a single oral dose of dehydroepiandrosterone (50 mg/day), whereas group 2 patients received a placebo. The International Index of Erectile Function was used to rate the success of this therapy. The patients in group 1 had a statistically significant increase in all domains of this index, in contrast to group 2 patients. Although our patient data are too small to perform a relevant statistical analysis, we believe that they represent a biologically obvious trend that justifies further extended studies.

ABSTRACT

OBJECTIVES: Nephrogenic adenoma is a benign metaplastic lesion of the urinary bladder, reported to occur as a response to inflammation, trauma, intravesical therapies, and after renal transplantation. The aim of this study was to evaluate on the basis of chromosomal analysis whether nephrogenic adenoma really is benign. METHODS: Twelve renal transplant recipients with histologically verified nephrogenic adenoma were analyzed for numerical aberrations of chromosomes 7, 9, and 17. Results were related to total DNA content, p53 and Ki-67 positivity, and clinical outcome. Ten patients with superficial bladder cancer and 10 healthy renal transplant recipients formed the control groups. RESULTS: All 12 patients with nephrogenic adenoma had monosomy 9 in a mean of 24.3% (range 20% to 30%) of the evaluated cells; 3 patients had an additional trisomy 7 in a mean of 8% (range 6% to 10%) of the counted cells. Chromosome 1 7 was disomic in all patients. DNA histograms were diploid in 11 of the 12 patients and aneuploid in 1 patient. No p53 and Ki-67 positivity was present in this group. All patients with superficial bladder cancer had monosomy 9 in a mean of 79.8% (range 75% to 85%) of the counted cells. Two patients were found to have an additional trisomy 7 in 50% and 65% of the cells, respectively. The latter had an aneuploid histogram; the others had haploid/diploid histograms. p53 was negative in all specimens. Ki-67 positivity was present in 70% of these patients. All healthy transplant recipients had disomic chromosomal patterns according to diploid DNA histograms and negative immunocytochemical results. CONCLUSIONS: Even if in a lower percentage of cells, aberrations of chromosome 7 and 9 were detected in nephrogenic adenoma. It therefore cannot be excluded that nephrogenic adenomas in immunosuppressed renal transplant recipients may develop into malignant lesions.

ABSTRACT

OBJECTIVES: During the past 25 years, radiotherapy has been considered the standard adjuvant treatment for clinical Stage I seminoma after orchiectomy. However, the late effects of this treatment have prompted a re-examination of the alternatives, including surveillance and adjuvant administration of carboplatin. To our knowledge, the present clinical study is the first to report the effects of two adjuvant courses of single-agent carboplatin on the pituitary-testicular axis and on sperm analysis. METHODS: Twenty-two patients with clinical Stage I seminoma participated in a prospective investigation of gonadal function before and after carboplatin therapy. After orchiectomy but before chemotherapy, blood samples for determination of follicle-stimulating hormone (FSH) serum levels were obtained from all 22 patients. Seventeen patients provided a semen sample at the same time, but 5 were unable to do so. At the end of chemotherapy, all 22 patients provided repeated semen samples starting 1 year after the termination of treatment and continuing at intervals of 12 months. FSH serum levels were determined at the same time. The study period was 48 months. RESULTS: Before chemotherapy, 2 patients (12%) had azoospermia, 9 (53%) had oligospermia, and 6 (35%) had normospermia. During the study period, sperm counts continued to increase in all patients. After 4 years, 7 patients (32%) had oligospermia and 15 (68%) normospermia. The mean prechemotherapy FSH level (15.5 IU/L) was increased in accordance with subnormal spermatogenesis, but a constant trend toward normalization was observed thereafter. CONCLUSIONS: Our results show recovery of spermatogenesis after adjuvant single-agent carboplatin for clinical Stage I seminoma in a remarkably high percentage of patients.

ABSTRACT

UNLABELLED: The effect of hydroxyethyl starch (HES) on hemostasis seems to be minimal when it is used in recommended amounts. A number of studies have investigated the effect of HES on platelet function when administered in vivo, but there has been no study investigating the effect on the isolated platelet function when administered in vitro. A photometrical method to assess platelet function in platelet-rich plasma (approximately 250 x 10(9) platelets/L) was used with platelet aggregation induced using either collagen, epinephrine, adenosine diphosphate, or ristocetin. We found a dose-dependent decrease of platelet aggregation in vitro with either collagen or epinephrine, but not with adenosine diphosphate or ristocetin. However, the changes of HES on platelet aggregation were detected only in doses larger than those routinely used in the clinical setting. Therefore, we conclude that the influence of HES at the recommended doses on initial platelet aggregation may not be clinically relevant. IMPLICATIONS: The effect of hydroxyethyl starch on platelet function and coagulation is discussed. This study showed no influence on platelets in clinically relevant doses in an in vitro model.

ABSTRACT

Spontaneous renal bleeding with diversion of blood into the subcapsular and/or perinephric spaces in a patient on chronic hemodialysis is a very rare clinical entity. We describe a patient on chronic hemodialysis in whom a spontaneous renal subcapsular hematoma and perirenal hemorrhage developed in a contracted kidney.
