RESUMEN
Overactive bladder and urgency incontinence are common and distressing conditions in older people, for which the first-line pharmacological treatment is a bladder antimuscarinic agent. Of these, oxybutynin is often recommended in guidelines, but is associated with a higher incidence of adverse drug effects, and in particular has been suggested to have deleterious cognitive effects. Despite this, guidelines often suggest oxybutynin as first-line treatment, and insurance based healthcare systems often require oxybutynin to be used as a first-line therapy and fail before reimbursement for the cost of newer anticholinergics is authorised. We reviewed the literature of bladder antimuscarinics in older adults, using the headings overactive bladder, urinary frequency, urgency, urge, oxybutynin, antimuscarinic, older, older people, and frail. In general, oxybutynin had a similar efficacy to other anticholinergic drugs, but a higher incidence of adverse drug events, in particular significant yet unnoticed cognitive impairment. We conclude that oxybutynin should not be used in frail older people.

OBJECTIVE: Angiogenesis is essential for tumor growth and metastasis; however, angiogenic factors are not uniformly expressed in prostate carcinoma. Our aim was to determine the expression of vascular endothelial growth factor-A (VEGF-A) and cyclooxygenase-2 (COX-2) in prostate carcinomas in relation to intratumoral microvessel density (MVD), tumor grade and androgen receptor (AR) status. MATERIALS AND METHODS: The expression of AR, VEGF-A and COX-2 was immunohistochemically evaluated in 24 benign prostatic hyperplasia (BPH) and 139 prostate carcinoma cases. MVD was evaluated by CD34 immunostaining. RESULTS: Nuclear AR expression was inversely related to tumor grade (p < 0.001). MVD was strongly related to tumor grade, VEGF-A and COX-2 (p < 0.001 in all comparisons). VEGF-A expression increased with tumor grade (p < 0.01) and was inversely related to stromal AR expression. COX-2 was present in both BPH and prostate carcinoma, but its expression increased with tumor grade (p < 0.01). High-grade neoplasms presented low-to-moderate VEGF staining intensity compared to strong COX-2 expression. CONCLUSIONS: Both VEGF-A and COX-2 expression is positively correlated with tumor grade and MVD. However, in Gleason 8-10 tumors, VEGF expression is moderate while COX-2 immunostaining is intense, suggesting a possible switch in the role of these two angiogenic factors in poorly differentiated neoplasms.

OBJECTIVE: To investigate the stability of tramadol hydrochloride 100mg associated with alizapride 50mg in 100ml of 5% dextrose solution stored at 5+/-3 degrees C. METHODS: Solutions of 5% dextrose 100ml in polyolefin bags (n=5) containing approximately tramadol hydrochloride 100mg associated with alizapride 50mg were prepared under aseptic conditions and stored about 32 days at 5+/-3 degrees C. The tramadol hydrochloride and alizapride concentrations were measured by high-performance liquid chromatography (HPLC). Visual inspection was performed and pH was measured periodically during the storage. Stability of the solutions was defined as the common regression line 95% lower confidence limit of the concentration remaining superior to 90% of the initial concentration as recommended by the Food and Drug Administration (FDA). RESULTS: No color change or precipitation in the solutions was observed. Tramadol hydrochloride 100mg associated with alizapride 50mg in 100ml of 5% dextrose infusions was stable when stored at 5+/-3 degrees C during 32 days. Throughout this period, the lower confidence limit of the estimated regression line of concentration-time profile remained above 90% of the initial concentration. There was no significant change in pH during storage. CONCLUSION: Under the conditions of this study, tramadol hydrochloride 100mg associated with alizapride 50mg in 100ml of 5% dextrose infusions stored up to 32 days at 5+/-3 degrees C remain stable and may be prepared in advance by a Centralized Intravenous Additive Service (CIVAS) to improve safety and management.

Our objective was to assess the effect of the selective alpha(1)-blocker alfuzosin on urodynamic parameters and quality of life in female patients with primary bladder neck obstruction (PBNO). Twenty-five women identified as having PBNO were included in the study. After the initial assessment of urodynamic parameters and bother score index, all patients were treated with alfuzosin 5 mg twice daily for 8 weeks. After this period of time, the patients were reassessed with the same methodology as pretreatment. Symptoms subjectively improved, and patients' satisfaction significantly increased in 64% of the patients (16 out of 25). Most urodynamic parameters were also significantly improved after treatment with alfuzosin. Alfuzosin significantly improved urodynamic parameters and alleviated bother score in almost two thirds of patients with PBNO and can be an effective first-line treatment of this situation.

A case of a urethral diverticulum following the insertion of a tension-free vaginal tape (TVT) is presented. The patient was a woman with stress urinary incontinence who underwent surgery to correct intrinsic sphincter deficiency. Three cases of urethral diverticula have been published thus far as complications of TVT insertions, but this is the first complication associated with intrinsic sphincter deficiency. The high pressures in the proximal urethra that result from positioning the TVT in the middle urethra, especially when obstruction co-exists with an open bladder neck, can be a predisposing factor for this complication. The possibility of a urethral diverticulum when postvoid incontinence occurs after the insertion of a TVT should be carefully evaluated.

PURPOSE: Rapid detection of Methicillin-Resistant Staphylococcus aureus (MRSA) is of major importance in hospital hygiene. In order to reduce the response time from screening laboratories, new selective chromogenic media have been developed and marketed by major microbiology companies. In this context, an evaluation of their performances was needed. MATERIALS AND METHODS: Media produced by Bio-Rad Laboratories (MRSASelect), Becton Dickinson (CHROMagar MRSA) and bioMérieux (chromID MRSA) were studied by 203screening samples, 110 of which were MRSA positive. Each Stahylococcus aureus was identified by catalase detection, Staphytect Plus Dryspot latex agglutination test and free coagulase detection, in addition to mannitol fermentation and Voges-Proskauer tests in the case of doubtful identification. Resistance was verified by checking the inhibition zone diameter of under 20 mm on 30 microg cefoxitin disks. RESULTS: Bio-Rad Laboratories, Becton Dickinson and bioMérieux media read at 24 or 24/48 hours have a respective sensitivity of 91, 71 and 85/92%. The specificity of these media is 99, 100 and 99/93%. CONCLUSION: These media proved to be new powerful and rapid tools used in screening for MRSA detection. MRSASelect is one of the most effective media showing high sensitivity and specificity and the easiest interpretation. chromID MRSA exhibits similar performance but needs more time to be as effective as Bio-Rad media while CHROMagar MRSA isn't enough efficient with its slightly lack of sensitivity to perform a reliable screening.

PURPOSE: To evaluate the efficacy of doxazosin in inducing spontaneous passage of stones in the distal ureter and to compare its efficacy according to the size of the stone. PATIENTS AND METHODS: Seventy-three patients with a mean age of 46.38 +/- 10.17 years who presented with a distal-ureteral stone were divided into four groups according to stone size and drug treatment: <5 mm without doxazosin (group A; n=15); 5-10 mm (group B; n=16); <5 mm with doxazosin 4 mg/day for 4 weeks (group C; n=20); and 5-10 mm with doxazosin 4 mg/day for 4 weeks (group D; n=22). Groups A and B served as controls for groups C and D, respectively. RESULTS: Spontaneous stone passage was documented in 9 patients (60%) in group A v 17 (85%) in group C (P=0.047) and 7 (43.75%) in group B v 16 (72.73%) in group D (P=0.036). The average expulsion time was 8.78 +/- 1.09 days in group A v 7.59 +/- 0.80 days in group C (P=0.004) and 12.14 +/- 1.35 days in group B v 7.06 +/- 1.29 days in group D (P<0.0001). The number of pain episodes in group D patients was significantly lower than in group B (P +/- 0.0078). CONCLUSIONS: Doxazosin treatment proved to be safe and effective for distal-ureteral stones, as determined by earlier expulsion, decreased colic frequency, and absence of side effects. The efficacy of doxazosin was significantly higher for 5-to 10-mm stones than for smaller ones.

A case of isolated, bilateral, adrenal tuberculosis is presented. A 25-year-old male was admitted to the hospital due to lumbar pain, fever, weight loss and anorexia. Abdominal ultrasonography and computed tomography demonstrated bilateral adrenal enlargement. Laboratory investigations were remarkable for adrenal insufficiency. The Mantoux reaction was positive but there was no evidence of lung or urinary infection. CT-guided biopsy of the left adrenal gland was performed and established the diagnosis of adrenal tuberculosis.

AIM: To assess the behavior of patients with diabetes mellitus (DM) and erectile dysfunction (ED) during 10 consecutive years of treatment with self-injection of vasoactive drugs. METHODS: Thirty-eight diabetic men, including 12 with type I and 26 with type II diabetes, were followed up regularly for 10 years after they began self-injecting for severe ED. Real time rigidity assessment was used for the objective determination of the initial dosage and then doses were regulated in order to introduce an erection suitable for penetration and maintenance of erection for approximately 30 min. Patients were followed up every two months, and doses were increased only when the treatment response was not satisfactory. RESULTS: The number of injections used per year by the patients was reduced each year (mean numbers: 50 in the first year and 22.5 in the 10th) and treatment shifted towards stronger therapeutic modalities (mixtures of vasoactive drugs instead of prostaglandin E1 alone). Type I diabetic men were standardized to a level of treatment as early as 5 years after the initiation of treatment. That level was finally reached by type II patients after another 4-5 years. CONCLUSION: Treatment with self-injections of vasoactive drugs in diabetic men with severe ED is a safe and effective alternative in the long term. Diabetic men of both types show the same preferences in quality and quantity of treatment after 10 years. The key point for maintenance in treatment is the adjustment of the therapeutic method and dosage to optimal levels for satisfactory erections.

PURPOSE: To report the safety and efficacy of percutaneous nephrostomy and primary antegrade recanalization for treatment of iatrogenic ureteral strictures after gynecologic surgery. PATIENTS AND METHODS: Ten women had symptoms suggestive of ureteral obstruction during the immediate postoperative period (5 days-1 week after surgery). Under analgesia and conscious sedation, standard percutaneous nephrostomy was performed, and a long 7F sheath was placed in the upper ureter. The obstructions were traversed with the aid of a 0.0035-inch Glidewire and a 5F angled Glide catheter (Terumo, Japan). Subsequently, the areas were dilated with angioplasty balloons to a maximum diameter of 7 mm. Finally, an 8F percutaneous internal/external nephroureteral drainage stent was inserted to secure ureteral patency. Follow-up was carried out by serial nephrostomography until removal of the stent and by renal ultrasonography thereafter. RESULTS: Twelve obstructions with a mean length of 1.4 cm (range 0.4-1.9 cm) were managed. The technical success rate was 100%. No major complications occurred, and normal renal function was restored. The mean follow-up was 12 months. In 60% of the patients, a patent ureter was depicted at 1 week, whereas in four patients, repeat dilation of the obstructed segment was required. The stents were removed after a mean period of 4.8 weeks. CONCLUSION: Percutaneous nephrostomy and primary antegrade ureteral balloon dilation is safe and efficacious for treating ureteral injury after pelvic surgery and obviates open surgical manipulations.

OBJECTIVE: The purpose of this study was to assess the relationship between the length of perineal body, the anal position index, the total fourchette-coccyx distance and the anal-coccyx length and female urodynamic stress urinary incontinence (USUI). PATIENTS AND METHODS: The study included 57 women with USUI (group A) and 45 women without USUI as control (group B). All patients underwent a urodynamic evaluation and measurement of the length of perineal body (PB) and the distance between the fourchette and the inferior margin of coccyx (FC). PB is the distance between the fourchette and the center of anal orifice. The ratio PB/FC is the anal position index. Subtracting the PB length from FC distance equals the anal-coccyx (AC) length. RESULTS: The student's t-test showed no significant statistical difference between any of the measured lengths in the two groups. Moreover, in the USUI group, ANOVA did not show any significant relationship between the urodynamic parameters and the measured lengths. Regarding to the investigated urodynamic parameters only the maximum urethral pressure (Pura max) presented a significant statistical difference between the two groups (P = 0.009). CONCLUSION: Theoretically, a differentiation of perineal distances probably brings to the surface a laxity of the pelvic floor, a factor predisposing to USUI. Furthermore, the anterior position of anus can be a cause of constipation which also contributes to USUI. However, our study did not reveal any relationship between the perineal length measurements and USUI. Further investigation with longer series of patients is needed to show if this simple, inexpensive and non-invasive test could be added in the armamentarium of the diagnostic and prognostic investigation of USUI. Regarding to the urodynamic parameters, our results emphasize the importance of the Pura max parameter in the urodynamic evaluation of USUI.

OBJECTIVE: To compare the efficacy of tolterodine and oxybutynin in the treatment of specific, according to their urodynamic grade of severity, populations with overactive detrusor. METHODS: In this open, randomized, two-way crossover study 128 women with urodynamically confirmed, idiopathic detrusor overactivity were recruited. Patients were categorized in 4 grades of severity groups, according to the characteristics of the first overactive detrusor contraction during filling cystometrogram: high volume-low pressure (grade-group I), high volume-high pressure (grade-group II), low volume-low pressure (grade-group III) and low volume-high pressure (grade-group IV). The primary outcome measure was average volume of voided urine per micturition. RESULTS: 107 patients successfully completed the study protocol and were included in the analyses: 40 in group IV, 36 in III, 25 in II and 6 in group I. In groups IV and III both oxybutynin and tolterodine significantly increased the average volume of voided urine per micturition but the differences between the drugs were not significant (p > 0.05). In group II neither of the drugs achieved significant changes in the outcome measure (p > 0.05). CONCLUSIONS: Tolterodine and oxybutynin are clinically equipotent in treating detrusor overactivity in specific severity groups of patients, although urodynamic effects are somewhat different.

Trials of the efficacy and safety of vardenafil in the treatment of male erectile dysfunction (ED) were meta-analysed. All available databases were searched (January 1, 2001-November 30, 2003). Trials were eligible if they included men with ED, compared vardenafil with placebo, were randomized, were at least of 12 weeks duration, and assessed clinically relevant outcomes. Two reviewers independently evaluated study quality and extracted data in a standardized fashion. Nine trials (6809 men) met the inclusion criteria. In results pooled from seven fixed-dose trials, vardenafil increases the Erectile Function domain of the International Index of Erectile Function questionnaire by 6.18 units (weighted mean difference (WMD)). Vardenafil also increases the percentage of erections firm enough to allow vaginal penetration (WMD: 26) and the percentage of sexual attempts that were successful per participant (WMD: 29.8). The percentage of men agreeing with the statement that 'the treatment they have been taking over the past 4 weeks improved their erections', is also in favour of vardenafil (relative risk (RR): 3). These efficacy variables appeared greater at higher doses, although there are no significant differences between 10 and 20 mg dose. The same results were extracted for the two flexible 'as needed' dosing trials. Discontinuations are greater at the vardenafil groups compared to placebo (RR: 2.25). Specific adverse events with vardenafil included flushing, dyspepsia, headache, and rhinitis. Vardenafil was not significantly associated with serious cardiovascular events or death. Vardenafil, in all treatment regimens, shows to possess superior efficacy to placebo in the treatment of patients with erectile dysfunction. More data is needed on patients' subgroups.

To compare the efficacy of apomorphine and sildenafil in men with nonarteriogenic erectile dysfunction (ED), 40 men were studied. Post-injection penile peak systolic velocity was greater than 25 cm s(-1). Twenty men started on apomorphine 2 mg and 20 on sildenafil 50 mg, the doses titrated up to 3 and 100 mg, respectively, if necessary. After a 1-week washout period each group switched to the other treatment mode. Efficacy was the percentage of attempts resulting in erections firm enough for intercourse, based on an event log data. The majority (85%) of the men had concomitant diseases, risk factors for ED and 95% were heavy smokers. The overall success rate of apomorphine was 62.7%, compared with 73.1% of sildenafil (Yates-corrected chi-square, P < 0.0004). The response to apomorphine 2 mg and sildenafil 50 mg was age related. Sildenafil was statistically more effective than apomorphine in impotent men with normal penile Doppler. Given the contraindication of sildenafil in men taking nitrates and the quick time of action of apomorphine, the two drugs are satisfactory first line therapeutic tools in such individuals and the choice should be based on patient's needs and preferences.

The aim of this study was to compare the efficacy of sildenafil and continuous positive airway pressure (CPAP) in men with erectile dysfunction (ED) and obstructive sleep apnea syndrome (OSAS). In all, 30 men were randomly treated for 12 weeks either with sildenafil 100 mg before intercourse (15 men) or CPAP during night time sleep (15 men). Under sildenafil, 97/180 (53.9%) of attempted intercourses were successful compared to 33/138 (23.9%) under CPAP. The mean IIEF (erectile function domain score) was 12.9 and 9.3 after sildenafil and CPAP treatment, respectively (P=0.007), compared to 7.9 and 7 at baseline. In all, 53.3% of patients were satisfied with sildenafil and 20% with CPAP for ED treatment (P=0.058). Although sildenafil was superior to CPAP, comorbidities and OSAS per se possibly resulted in a lower effectiveness of sildenafil compared to that in the general population of ED men. While about half of the patients were not satisfied even with the more effective treatment, we conclude that a combination of the two therapeutic tools or a different therapeutic mode should be studied further.

The aim of the study was to establish and compare the efficacy and safety of sildenafil and apomorphine in men with arteriogenic erectile dysfunction (ED). In all, 43 men with ED and postinjection max penile systolic velocity <25 cm/s in repeated Doppler ultrasonography were included. Of these, 24 men started on apomorphine 2 mg and 19 on sildenafil 50 mg, the doses titrated up to 3 and 100 mg according to effectiveness and tolerability. Safety was evaluated according to adverse events (AEs) and patient withdrawal. Efficacy was the percentage of attempts resulting in erections firm enough for intercourse, based on event log data. The incidence of AEs with apomorphine 3 mg was higher than with sildenafil 100 mg. Two men on apomorphine 3 mg discontinued treatment due to AEs. The overall success rate of sildenafil was 63.7% compared to 32.1% of apomorphine (Pearson chi(2), P<0.01). Of all men, 25 (58.1%) responded to sildenafil 50 mg without the need for dose increase, while only one responded to apomorphine 2 mg. The response to sildenafil 50 mg was age related (analysis of variance, p=0.04). Satisfaction was reported by 76.75 and 13.95% of patients for sildenafil and apomorphine, respectively, but 20.9% were not satisfied with any of the two drugs. In conclusion, this study provides clear evidence that sildenafil, even at 50 mg dose, is more effective than apomorphine 3 mg in men with arteriogenic ED. The fact that one out of five patients is not satisfied with the above-studied drugs shows that new oral agents need to be evaluated for the treatment of this disorder.

Recurrent idiopathic priapism is a difficult problem to treat and a true emergency for the physicians, and often even invasive therapeutic interventions fail. We recently managed three men with refractory idiopathic priapism with oral gabapentin. They responded to treatment within 48 h. Two men continue not to experience prolonged erections while treated with lower doses of gabapentin for 16 and 24 months, respectively. The third, after a successful treatment for 6 months, stopped gabapentin and priapism recurred. He responded to treatment again and continues to be free of episodes for 9 months. Gabapentin may be a safe alternative for the management of refractory idiopathic priapism.

We assessed the long-term efficacy of a modified transvaginal needle bladder neck suspension, combined with vaginal hysterectomy, for the treatment of female stress incontinence. Thirty-two women who underwent this procedure were followed up clinically and urodynamically 1 and 5 years postoperatively. A total of 27 women (84.4%) were cured 1 year postoperatively. Of the 29 women who were followed up 5 years postoperatively, 21 (72.4%) had a satisfactory result (p = 0.157). No significant differences were observed in maximum urine flow rate, residual volume of urine, and functional length of the urethra. On the contrary, the maximum urethral closure pressure was significantly decreased (p = 0.004). Although the results of our study show a decline in success rate by time, the overall long-term efficacy of this technique is undoubtedly satisfactory. This technique is promising as an easy and minimally invasive surgical procedure for bladder neck suspension.
