Six-year follow-up of azathioprine and mycophenolate mofetil use during the first 6 months of renal transplantation

Long-term follow-up examination to test whether therapy with mycophenolate mofetil (MMF) or azathioprine (AZA) during the first year translates into different graft or patient survival and graft function is important. Therefore, 6-year follow-up data of a group of 80 consecutive renal transplant recipients were analyzed. The first group of 40 patients was treated with AZA, cyclosporine and prednisone and the second group with MMF, cyclosporine and prednisone for the first 6 months. Graft failure rates were compared during follow-up. Creatinine, inverse slope of creatinine (delta/creatinine) and 24-hour proteinuria at 6 years post transplantation were compared. The Kaplan-Meier analyses for death-censored and non-censored graft failure showed no difference between the groups. Creatinine values at 6 years for the AZA Group were 139 +/- 36 micromol/l (95% CI 125.9-151.2 micromol/l) and for the MMF Group 149 +/- 52 micromol/l (95% CI 133.9-164.9 micromol/l). Delta/creatinine and 24-hour proteinuria at 6 years did not differ between the two groups. We conclude that an initial 6-month treatment with MMF as opposed to AZA reduced the early rejection rate, but did not result in superior long-term graft function or survival after 6 years of follow-up observation.

Long-term followup results of 1 cycle of adjuvant bleomycin, etoposide and cisplatin chemotherapy for high risk clinical stage I nonseminomatous germ cell tumors of the testis

PURPOSE: We evaluated the long-term outcome after 1 cycle of adjuvant modified bleomycin, etoposide and cisplatin chemotherapy in patients who underwent orchiectomy for high risk clinical stage I nonseminomatous germ cell tumor of the testis. MATERIALS AND METHODS: Between 1995 and 1999 a consecutive series of 44 patients underwent orchiectomy for clinical stage I nonseminomatous germ cell tumor of the testis, followed by a single postoperative cycle of adjuvant modified bleomycin, etoposide and cisplatin for vascular or lymphatic tumor invasion, and/or a predominance (50% or greater) of embryonal carcinoma. RESULTS: Four of the 44 patients were excluded from analysis. Of the patients 35 had no evidence of disease at a median followup of 99 months (range 60 to 134). One patient with progression after 13 months showed complete remission after 3 cycles of salvage bleomycin, etoposide and cisplatin chemotherapy but he died of pneumonia 4 weeks after the third course. Two patients underwent orchiectomy for contralateral testis cancer at 18 and 42 months, respectively, followed by an additional 3 cycles of adjuvant chemotherapy. They remained relapse-free for 4 and 92 months, respectively. The former patient was lost to followup after 4 months. Two other patients were disease-free at 10 and 31 months, respectively, and were lost to followup thereafter. Late side effects were tinnitus in 3 patients and involuntary childlessness in 3, of whom 2 had cryptorchidism of the contralateral testis. Nine patients fathered children. CONCLUSIONS: One cycle of bleomycin, etoposide and cisplatin effectively decreases the risk of relapse in patients with high risk stage I nonseminomatous germ cell tumor of the testis. It has minimal side effects and can be a valuable alternative to retroperitoneal lymph node dissection.

Childhood extraordinary daytime urinary frequency-a case series and a systematic literature review

Childhood extraordinary daytime urinary frequency is likely a common but underreported condition characterized by daytime frequent voiding and typically not linked with complaints of burning, urinary incontinence, altered urinary stream, changes in the nighttime voiding pattern, excessive fluid intake and excessive urinary volume. To determine the features and outcome of extraordinary daytime urinary frequency, we report our experience with 14 children and the results of a formal systematic analysis of peer-reviewed English-language literature on this topic. Nineteen case series were found (together with 16 mostly pertinent comments), with each case series providing details on from one to 119 children. On the basis of our experience and the findings of our systematic analysis, we conclude that, in general practice, extraordinary daytime urinary frequency is a common cause of urinary frequency, that the age of such patients is, on average, 6 years and that the micturation abnormalities persist for an average of 6 months. The results of this review must be viewed with an understanding of the limitations of the analysis process, which incorporated data exclusively from case series.

Correction of erosion after suburethral sling insertion for stress incontinence: results and related sexual function

BACKGROUND: Suburethral slings are commonly used for the surgical treatment of female stress incontinence; occasionally they can cause erosion and dyspareunia. OBJECTIVES: The primary aim of this study is to determine the outcome after reclosure of the vaginal epithelium for suburethral sling erosion. Sexual function was assessed before and after intervention using the Female Sexual Function Index (FSFI) questionnaire. DESIGN, SETTING, AND PARTICIPANTS: This was a prospective case-controlled study in which, between December 2005 and December 2007, we included patients who were referred to the Department of Urogynaecology because of vaginal erosion after suburethral sling insertion for urinary stress incontinence. For evaluation of sexual function, all patients filled in an FSFI questionnaire before intervention and at follow-up. All patients underwent gynaecological examination including colposcopy, and the site and size of the defect were noted. INTERVENTION: The edge of the vaginal epithelium was trimmed, mobilized, and closed with interrupted vertical Vicryl mattress sutures in a single layer. MEASUREMENTS: FSFI questionnaire and clinical findings. RESULTS AND LIMITATIONS: Twenty-one patients were included in the study. Eighteen patients with larger defects were operated on, and three defects healed after topical application of estrogen cream. In 16 patients, the defect had healed at follow-up; two patients with persisting defects were brought back to surgery and the procedure was repeated, paying particular attention to tension-free adaptation of vaginal tissue. In one patient, partial sling removal was performed after the second failed intervention. The domains of desire (p<0.0001), arousal (p<0.0003), lubrication (p<0.0001), satisfaction (p<0.0130), and pain (p<0.0001) improved significantly. Orgasm remained unchanged (p=0.4130; all two-tailed t-test). CONCLUSION: Suburethral erosion can be treated effectively by resuturing. Sexual function is improved in regard to desire, arousal, lubrication, satisfaction, and pain, but not orgasm. In septic patients and patients with a history of radiation, grossly infected tissue, or severe pain, excision of the mesh needs to be considered.

Androgen deprivation therapy for the treatment of prostate cancer: consider both benefits and risks

CONTEXT: Androgen deprivation therapy (ADT) is increasingly used for the treatment of prostate cancer (PCa), even in clinical settings in which there is no evidence-based proof of prolonged overall survival (OS). ADT, however, may be associated with numerous side effects, including an increased therapy-related cardiovascular mortality. OBJECTIVE: To discuss different clinical settings in which ADT is currently used and to critically weigh the benefits of ADT against its possible side effects. EVIDENCE ACQUISITION: A MEDLINE search was conducted to identify original articles and review articles addressing the efficacy and side effects of ADT for the treatment of PCa. Keywords consisted of prostate cancer, hormonal therapy, adverse effects, radical prostatectomy, and radiotherapy. The articles with the highest level of evidence for the various examined end points were identified with the consensus of all authors and were reviewed. EVIDENCE SYNTHESIS: Even short-term use of ADT may lead to numerous side effects, such as osteoporosis, obesity, sarcopenia, lipid alterations, insulin resistance, and increased risk for diabetes and cardiovascular morbidity. Despite these side effects, ADT is commonly used in various clinical settings in which a clear effect on improved OS has not been shown. CONCLUSIONS: ADT is associated with an increased risk of multiple side effects that may reduce quality of life and/or OS. Consequently, these issues should be discussed in detail with patients and their families before initiation of ADT. ADT should be used with knowledge of its potential long-term side effects and with possible lifestyle interventions, especially in settings with the highest risk-benefit ratio, to alleviate comorbidities.

To stent or not to stent perioperatively the ureteroileal anastomosis of ileal orthotopic bladder substitutes and ileal conduits? Results of a prospective randomized trial

PURPOSE: We evaluated the impact of stenting the ureteroileal anastomosis on its competence, upper urinary tract dilatation, gastrointestinal recovery, metabolic parameters and patency rate after cystectomy with ileal bladder substitution or ileal conduit. MATERIALS AND METHODS: A total of 54 patients (37 with an ileal bladder substitute and 17 with an ileal conduit) were prospectively randomized into 2 groups, with (29) or without (25) perioperative stenting of the ureteroileal anastomosis. In all cases an end-to-side ureteroileal refluxing anastomosis was performed. The stents were removed after 5 to 10 days. The parameters assessed postoperative days 1, 3 and 7 were creatinine concentration from the wound drains, upper urinary tract dilatation, time to bowel function recovery, serum creatinine, as well as urea and incidence of metabolic acidosis. RESULTS: Median patient age was 68 years (range 45 to 85). Urine leak on postoperative day 1 was more frequent in those anastomoses without stents, and on postoperative days 3 and 7 the values were comparable. Stenting of the ureteroileal anastomosis resulted in significantly decreased early postoperative upper urinary tract dilatation, improved recovery of bowel function and decreased metabolic acidosis. In either group no patient had clinical evidence of ureteroileal anastomotic stricture during the early postoperative period. Three patients with perioperative stenting required surgical or endoscopic treatment for a stricture of the ureteroileal anastomosis during the 12-month followup. CONCLUSIONS: Stenting of the ureteroileal anastomosis allows for significantly less frequent incidence of early postoperative dilatation of the pelvicaliceal system, bowel activity resumes significantly earlier and metabolic acidosis is significantly less frequent.

Air charged and microtip catheters cannot be used interchangeably for urethral pressure measurement: a prospective, single-blind, randomized trial

PURPOSE: We determined and compared urethral pressure measurements using air charged and microtip catheters in a prospective, single-blind, randomized trial. MATERIALS AND METHODS: A consecutive series of 64 women referred for urodynamic investigation underwent sequential urethral pressure measurements using an air charged and a microtip catheter in randomized order. Patients were blinded to the type and sequence of catheter used. Agreement between the 2 catheter systems was assessed using the Bland and Altman 95% limits of agreement method. RESULTS: Intraclass correlation coefficients of air charged and microtip catheters for maximum urethral closure pressure at rest were 0.97 and 0.93, and for functional profile length they were 0.9 and 0.78, respectively. Pearson's correlation coefficients and Lin's concordance coefficients of air charged and microtip catheters were r = 0.82 and rho = 0.79 for maximum urethral closure pressure at rest, and r = 0.73 and rho = 0.7 for functional profile length, respectively. When applying the Bland and Altman method, air charged catheters gave higher readings than microtip catheters for maximum urethral closure pressure at rest (mean difference 7.5 cm H(2)O) and functional profile length (mean difference 1.8 mm). There were wide 95% limits of agreement for differences in maximum urethral closure pressure at rest (-24.1 to 39 cm H(2)O) and functional profile length (-7.7 to 11.3 mm). CONCLUSIONS: For urethral pressure measurement the air charged catheter is at least as reliable as the microtip catheter and it generally gives higher readings. However, air charged and microtip catheters cannot be used interchangeably for clinical purposes because of insufficient agreement. Hence, clinicians should be aware that air charged and microtip catheters may yield completely different results, and these differences should be acknowledged during clinical decision making.
