RESUMO

BACKGROUND: Prostatic inflammation is an important etiological component of benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS). The Prostatic Inflammation Nomogram Study (PINS) aimed to develop and validate a nomogram for predicting the presence of prostatic inflammation in men with LUTS. METHODS: This non-interventional, cross-sectional, prospective study was conducted in six secondary/tertiary centers across Cyprus, Greece, Italy, Portugal, and Spain. Men (≥40 years) with BPH/LUTS scheduled to undergo prostatic surgery or transrectal ultrasound-guided (TRUS) prostate biopsy were included. Fifteen demographic and clinical participant characteristics were selected as possible predictors of prostatic inflammation. The presence of inflammation (according to Irani score) in the prostatic tissue samples obtained from surgery/TRUS biopsy was determined. The effect of each characteristic on the likelihood a prostate specimen demonstrated inflammation (classified by Irani score into two categories, 0-2 [no/minimal inflammation] or 3-6 [moderate/severe inflammation]) was assessed using multiple logistic regression. A nomogram was developed and its discriminatory ability and validity were assessed. RESULTS: In total, 423 patients (mean age 68.9 years) were recruited. Prostate volume ultrasound (PVUS) > 50 mL, history of urinary tract infection (UTI) treatment, presence of diabetes, and International Prostate Symptom Score (IPPS) Storage score were statistically significant predictors of Irani classification. Logistic regression demonstrated a statistically significant effect for leucocytes detected via urine dipstick, presence of diabetes, PVUS > 50 mL, history of UTIs, and higher IPSS Storage score for the odds of an inflammatory score category of 3-6 versus 0-2. The nomogram had a concordance index of 0.71, and good internal validity. CONCLUSIONS: The nomogram developed from PINS had good predictive ability and identified various characteristics to be predictors of prostatic inflammation. Use of the nomogram may aid in individualizing treatment for LUTS, by identifying individuals who are candidates for therapies targeting prostatic inflammation.

RESUMO

PURPOSE: T1 bladder cancer is known for its high progression and recurrence rates. Identifying aggressive tumours at the non-muscle-invasive stage is crucial to allow early interventions and subsequently increase patient survival. This study aimed to investigate the potential of the cubilin/myeloperoxidase (CUBN/MPO) ratio as a high-grade T1 bladder cancer biomarker. METHODS: Urine samples were collected from 30 patients who underwent transurethral resection of the tumour with high-grade T1 bladder cancer (June 2015 to December 2019) before surgery. The urinary proteome was analysed using high-resolution mass spectrometry and the CUBN/MPO ratio was calculated. The primary outcome was the recurrence during the follow-up (around 31.5 months after resection). Univariate Cox regression and Kaplan-Meier curves were used for data analysis. RESULTS: Patients with a low CUBN/MPO ratio exhibited upregulated MPO and/or downregulated CUBN. This group of patients had a higher incidence of disease recurrence and progression. Low CUBN/MPO ratio was significantly associated with a higher likelihood of recurrence, progression, and death. It is worth noting that this study was exploratory and conducted on a small sample size, so further research is needed to validate these findings in larger cohorts. CONCLUSION: This study highlights the potential of the CUBN/MPO ratio as a prognostic biomarker for high-grade T1 bladder cancer.

RESUMO

BACKGROUND: This study investigates the proteomic landscapes of chromophobe renal cell carcinoma (chRCC) and renal oncocytomas (RO), two subtypes of renal cell carcinoma that together account for approximately 10% of all renal tumors. Despite their histological similarities and shared origins, chRCC is a malignant tumor necessitating aggressive intervention, while RO, a benign growth, is often subject to overtreatment due to difficulties in accurate differentiation. METHODS: We conducted a label-free quantitative proteomic analysis on solid biopsies of chRCC (n = 5), RO (n = 5), and normal adjacent tissue (NAT, n = 5). The quantitative analysis was carried out by comparing protein abundances between tumor and NAT specimens. Our analysis identified a total of 1610 proteins across all samples, with 1379 (85.7%) of these proteins quantified in at least seven out of ten LC‒MS/MS runs for one renal tissue type (chRCC, RO, or NAT). RESULTS: Our findings revealed significant similarities in the dysregulation of key metabolic pathways, including carbohydrate, lipid, and amino acid metabolism, in both chRCC and RO. Compared to NAT, both chRCC and RO showed a marked downregulation in gluconeogenesis proteins, but a significant upregulation of proteins integral to the citrate cycle. Interestingly, we observed a distinct divergence in the oxidative phosphorylation pathway, with RO showing a significant increase in the number and degree of alterations in proteins, surpassing that observed in chRCC. CONCLUSIONS: This study underscores the value of integrating high-resolution mass spectrometry protein quantification to effectively characterize and differentiate the proteomic landscapes of solid tumor biopsies diagnosed as chRCC and RO. The insights gained from this research offer valuable information for enhancing our understanding of these conditions and may aid in the development of improved diagnostic and therapeutic strategies.

RESUMO

Oxalate is a metabolic end-product whose systemic concentrations are highly variable among individuals. Genetic (primary hyperoxaluria) and non-genetic (e.g., diet, microbiota, renal and metabolic disease) reasons underlie elevated plasma concentrations and tissue accumulation of oxalate, which is toxic to the body. A classic example is the triad of primary hyperoxaluria, nephrolithiasis, and kidney injury. Lessons learned from this example suggest further investigation of other putative factors associated with oxalate dysmetabolism, namely the identification of precursors (glyoxylate, aromatic amino acids, glyoxal and vitamin C), the regulation of the endogenous pathways that produce oxalate, or the microbiota's contribution to oxalate systemic availability. The association between secondary nephrolithiasis and cardiovascular and metabolic diseases (hypertension, type 2 diabetes, and obesity) inspired the authors to perform this comprehensive review about oxalate dysmetabolism and its relation to cardiometabolic toxicity. This perspective may offer something substantial that helps advance understanding of effective management and draws attention to the novel class of treatments available in clinical practice.

RESUMO

Seminal vesicle calculi are a rare entity that may present with hematospermia, painful ejaculation, or urinary complaints. We present a case of a 40-year-oldmale with complaints of hematospermia, ejaculatory pain, and perineal discomfort in the last five years. A 7 mm left seminal vesicle calculi were diagnosed by magnetic resonance imaging (MRI), and a laparoscopic robot-assisted vesiculectomy was performed. All the complaints improved completely after treatment. Seminal vesicle lithiasis should be kept in mind when evaluating patients with hematospermia and ejaculatory pain. Transrectal ultrasound (TRUS) and magnetic resonance imaging are the best radiology techniques to diagnose this kind of lithiasis. Different surgical treatments can be used to treat these calculi, depending on the size and location of the calculi and the surgical experience of the surgeon.

RESUMO

Introduction: Patients with bladder exstrophy subjected to reconstructive surgeries are at risk of developing urinary calculus. Case presentation: We report the case of a 29-year-old male patient with bladder exstrophy who presented with a recurrent episode of extrusion of calculus through the neobladder and anterior abdominal wall. Calculus removal and reconstructive repair of the neobladder and abdominal wall were performed in 2010. Nine years following the procedure, the patient returned with new large neobladder calculus extrusion. Conclusion: Recurrence of large calculus should be seen as the new paradigm for the importance of close follow-up in bladder exstrophy patients.

RESUMO

Primary renal synovial sarcoma (PRSS) is an extremely rare malignancy. The diagnosis of PRSS is unforeseen due to the absence of clinical and radiological typical aspects. Here, we present a case of a 69-year-old male with complaints of hematuria and left lumbar pain. Abdominal-pelvic computed tomography scan with contrast injection showed a solid mass of 8cm diameter in the left kidney and renal vein tumor thrombus. The patient was further subjected to robotic-assisted left radical nephrectomy and renal vein thrombectomy. We concomitantly performed left adrenalectomy and paraaortic lymphadenectomy. Immunohistochemical and genetic analysis revealed PRSS. This entity is characterized by abnormal chromosomal translocation t(X;18)(p11.2; q11.2) and consequently the characteristic SYT-SSX fusion gene. Due to the disease's rarity and severity, diagnosis and management of PRSS rely upon a demanding and multidisciplinary approach.

RESUMO

Small-cell bladder cancer (SCBC) is a rare subtype of bladder cancer with aggressive behavior and poor prognosis. Here, we report the case of a 50-year-old man who presented with hematuria for one month. A computed tomography scan showed an exophytic lesion on the right posterolateral wall of the bladder and a single liver metastasis with a 14 mm diameter. Transurethral resection of the bladder tumor was performed, and postoperative examination of the specimen showed muscle-invasive SCBC. Initially, the patient was treated with neoadjuvant chemotherapy. Rapid clinical and imaging deterioration was observed after the premature end of cisplatin and etoposide therapy. Second-line therapy with nivolumab demonstrated systemic and local complete response. However, the patient was further diagnosed with unpredictable and unexpected urothelial muscle-invasive bladder cancer. After 76 months of regular follow-up, imaging workup did not demonstrate SCBC recurrence or urothelial bladder cancer progression. This report highlights this disease's rarity and severity and no typical or even pathognomonic clinical and radiological presentation. Therefore, histopathology and immunohistochemistry findings play a key role in diagnosis. Immunotherapy has opened a new window in cancer treatment and maybe SCBC patients can benefit from it.

RESUMO

OBJECTIVES: The aim of this study was to com-pare the risk of International Society of Urological Pathology (ISUP) score upgrading between magnetic resonance imaging targeted fusion biopsy (MRI-TB) and tran-srectal ultrasound-guided biopsy (TRUS-B) in the final radical prostatectomy (RP) specimen pathological report. MATERIALS AND METHODS: This retrospective single center study included 51 patients with prostate cancer (PCa) diagnosed with MRI-TB and 83 patients diagnosed with TRUS-B between October/2019 and July/2021. We compared the rates of ISUP score upgrading between both groups after robotic-assisted radi-cal prostatectomy (RARP) and the specific transition of each ISUP score based on biopsy modality. The rate of ISUP score concordance and downgrading were also assessed. To define the intra and interobserver concordance for each ISUP score in biopsy and RP specimen for each biopsy modality, the Cohen's Kappa coefficient was calculated. ISUP scores and biopsy modal-ity were selected for multivariate analysis and a logistic regres-sion model was built to provide independent risk factors of ISUP score upgrading. RESULTS: The difference of the rate of upgrading between MRI-TB group and TRUS-B group was statistically significant (p = 0.007) with 42.2% of patients of TRUS-B group experiencing an upgrade in their ISUP score while only 19.6% in MRI-TB group. Concordance and downgrading rates did not statistically differ between the two groups. Strength of concordance using Cohen's Kappa coefficient was fair in both groups but higher in MRI-TB group (TRUS-B group k = 0.230; p < 0.001; concordance: 47%vs. MRI/TB group k = 0.438; p < 0.001; concordance: 62.7%). Biopsy modality and ISUP 1 on biopsy were independent predic-tors of ISUP upgrading after RP. CONCLUSIONS: MRI-TB is highly accurate with lower risk of PCa upgrading after RP than TRUS-B. Patients with ISUP 1 on biopsy have greater susceptibility to upgrading their ISUP score.

RESUMO

PURPOSE: Multidisciplinary team (MDT) conferences are currently the standard of care in cancer patients' management. Despite evidence supporting benefits to the majority of malignancies, a paucity of data exists examining the impact in urinary and male genital cancers. This study aims to evaluate the impact of MDT conferences in urologic cancer practice. METHODS: Clinical plans discussed in urologic MDT conferences in Centro Hospitalar Universitário de Lisboa Central between January 2019 and December 2019 were retrospectively analysed. Clinical plans were categorized as accepted, changed, rejected (cases that had to be re-presented to the MDT because of insufficient staging or administrative issues) or no plan. MDT conferences' impact was assessed according to type of consultation, referral medical specialty and primary tumour type. RESULTS: 710 clinical plans were discussed at the MDT conferences. 61.8% were accepted, 10.6% were changed, 16.5% were rejected and 11.1% of cases referred to MDT discussion had no defined clinical plan. First consultations had a higher rate of accepted clinical plans (63.4%) versus subsequent consultations (56.4%). Referrals by the urology specialty had the highest rate of acceptances (64.3%). On the stratification by primary tumour site, testicular cancer had the highest acceptance rate (70.3%), whereas bladder cancer had the lowest (47.8%). CONCLUSIONS: MDT conferences had an important impact in the management of 38.2% of cases. Therefore, all patients with urologic malignancies should be referred to MDT review to ensure optimal clinical care.

RESUMO

The retrocaval ureter is a rare congenital entity, classically managed with open pyeloplasty techniques. The experience obtained with the laparoscopic approach of other more frequent causes of ureteropelvic junction (UPJ) obstruction has opened the method for the minimally invasive approach of the retrocaval ureter. In our paper, we describe a clinical case of a right retrocaval ureter managed successfully with laparoscopic dismembered pyeloplasty. The main standpoints of the procedure are described. Our results were similar to others published by other urologic centers, which demonstrates the safety and feasibility of the procedure for this condition.

RESUMO

Purpose To assess predictors of outcome after prostate artery embolization (PAE) for benign prostatic hyperplasia with spherical particle polyvinyl alcohol (sPVA) and compare outcomes with the use of nonspherical particle polyvinyl alcohol (nsPVA). Materials and Methods This was a single-center retrospective institutional review board-approved study conducted from 2009 to 2015 in patients undergoing PAE with sPVA (n = 186; mean age ± standard deviation, 65.5 years ± 7.7) and nsPVA (n = 300; mean age, 65.3 years ± 7.6). The two cohorts were compared and analyzed for predictors of outcome with a Cox proportional hazards model and linear regression. Post-PAE prostate ischemia was measured with contrast material-enhanced magnetic resonance (MR) imaging in 23 patients with nsPVA and 25 patients with sPVA. The 24-hour post-PAE prostate-specific antigen (PSA) level was registered in 133 patients with sPVA. Prognostic values of MR imaging and PSA levels 24 hours after PAE were assessed with Cox and random-effects regressions. Results Predictors of clinical failure were older age (age over 65 years, P = .002), unilateral procedure (P = .002), and higher baseline International Prostate Symptom Score (IPSS, P = .033). Adjusted hazard ratio for clinical failure of sPVA was 1.273 (P = .16). Acute urinary retention was a predictor of lower IPSS after PAE (P = .002). The mean proportion of prostate ischemia was 11% with sPVA and 10% with nsPVA (P = .65). Lower IPSS after PAE was associated with a higher proportion of prostate ischemia (P = .009). Patients with a PSA level of at least 75 ng/mL (75 µg/L) 24 hours after PAE had a greater decrease in IPSS (P = .01). Prostate ischemic volume and PSA level 24 hours after PAE were correlated (Pearson r = 0.64, P = .014). Conclusion Clinical outcome was similar after PAE with sPVA and nsPVA. Younger age (up to 65 years), bilateral PAE, lower baseline IPSS, and acute urinary retention were predictors of better clinical outcome. The PSA level 24 hours after PAE correlated with prostate ischemia, and both correlated with clinical outcome. (©) RSNA, 2016.

RESUMO

The use of multiparametric magnetic resonance imaging (mp-MRI) for prostate cancer has increased over recent years, mainly for detection, staging, and active surveillance. However, suspicion of recurrence in the set of biochemical failure is becoming a significant reason for clinicians to request mp-MRI. Radiologists should be able to recognize the normal post-treatment MRI findings. Fibrosis and atrophic remnant seminal vesicles after prostatectomy are often found and must be differentiated from local relapse. Moreover, brachytherapy, external beam radiotherapy, cryosurgery, and hormonal therapy tend to diffusely decrease the signal intensity of the peripheral zone on T2-weighted images (T2WI) due to the loss of water content, consequently mimicking tumor and hemorrhage. The combination of T2WI and functional studies like diffusion-weighted imaging and dynamic contrast-enhanced improves the identification of local relapse. Tumor recurrence tends to restrict on diffusion images and avidly enhances after contrast administration either within or outside the gland. The authors provide a pictorial review of the normal findings and the signs of local tumor relapse after radical prostatectomy, external beam radiotherapy, brachytherapy, cryosurgery, and hormonal therapy.

RESUMO

PURPOSE: To evaluate whether different polyvinyl alcohol (PVA) particle sizes change the outcome of prostatic arterial embolization (PAE) for benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: A randomized prospective study was undertaken in 80 patients (mean age, 63.9 y; range, 48-81 y) with symptomatic BPH undergoing PAE between May and December 2011. Forty patients underwent PAE with 100-µm (group A) and 200-µm PVA particles (group B). Visual analog scales were used to measure pain, and rates of adverse events were recorded. PAE outcomes were evaluated based on International Prostate Symptom Score (IPSS) and quality-of-life (QoL) questionnaires, prostate volume (PV), prostate-specific antigen (PSA) levels, and peak flow rate measurements at baseline and 6 months. RESULTS: No differences between groups regarding baseline data, procedural details, or adverse events were noted. Mean pain scores were as follows: during embolization, 3.2 ± 2.97 (group A) versus 2.93 ± 3.28 (group B); after embolization, 0.10 ± 0.50 (group A) versus 0 (group B; P = .20); and the week after PAE, 0.85 ± 1.65 (group A) versus 0.87 ± 1.35 (group B; P = .96). Patients in group B had greater decreases in IPSS (3.64 points; P = .052) and QoL (0.57 points; P = .07). Patients in group A had a greater decrease in PV (8.75 cm(3); P = .13) and PSA level (2.09 ng/mL; P < .001). CONCLUSIONS: No significant differences were found in pain scores and adverse events between groups. Whereas PSA level and PV showed greater reductions after PAE with 100-µm PVA particles, clinical outcome was better with 200-µm particles.

RESUMO

OBJECTIVES: To evaluate the short- and medium-term results of prostatic arterial embolisation (PAE) for benign prostatic hyperplasia (BPH). METHODS: This was a prospective non-randomised study including 255 patients diagnosed with BPH and moderate to severe lower urinary tract symptoms after failure of medical treatment for at least 6 months. The patients underwent PAE between March 2009 and April 2012. Technical success is when selective prostatic arterial embolisation is completed in at least one pelvic side. Clinical success was defined as improving symptoms and quality of life. Evaluation was performed before PAE and at 1, 3, 6 and every 6 months thereafter with the International Prostate Symptom Score (IPSS), quality of life (QoL), International Index of Erectile Function (IIEF), uroflowmetry, prostatic specific antigen (PSA) and volume. Non-spherical polyvinyl alcohol particles were used. RESULTS: PAE was technically successful in 250 patients (97.9 %). Mean follow-up, in 238 patients, was 10 months (range 1-36). Cumulative rates of clinical success were 81.9 %, 80.7 %, 77.9 %, 75.2 %, 72.0 %, 72.0 %, 72.0 % and 72.0 % at 1, 3, 6, 12, 18, 24, 30 and 36 months, respectively. There was one major complication. CONCLUSIONS: PAE is a procedure with good results for BPH patients with moderate to severe LUTS after failure of medical therapy. KEY POINTS: • Prostatic artery embolisation offers minimally invasive therapy for benign prostatic hyperplasia. • Prostatic artery embolisation is a challenging procedure because of vascular anatomical variations. • PAE is a promising new technique that has shown good results.

RESUMO

PURPOSE: To evaluate the safety, morbidity, and short- and intermediate-term results of prostatic arterial embolization (PAE) for benign prostatic hyperplasia (BPH) after failure of medical treatment. MATERIALS AND METHODS: This prospective study was approved by the institutional review board, and informed consent was obtained from all participants. Men older than 50 years with a diagnosis of BPH and moderate-to-severe lower urinary tract symptoms that were refractory to medical treatment for 6 months were eligible. PAE with nonspherical 80-180-µm (mean, 100-µm) and 180-300-µm (mean, 200-µm) polyvinyl alcohol particles was performed by means of a single femoral approach in most cases. Effectiveness variables of International Prostate Symptom Score (IPSS), quality of life (QOL) score, peak urinary flow, postvoid residual volume, International Index Erectile Function (IIEF) score, prostate volume, and prostate-specific antigen level were assessed for up to 24 months after the procedure. Statistical analysis included the Kaplan-Meier method and random-effects generalized least squares regression with autoregressive disturbance. RESULTS: Eighty-nine consecutive patients (mean age, 74.1 years) were included. PAE was technically successful in 86 of the 89 patients (97%). Cumulative rates of clinical improvement in these patients were 78% in the 54 patients evaluated at 6 months and 76% in the 29 patients evaluated at 12 months. At 1-month follow-up, IPSS decreased by 10 points, QOL score decreased by 2 points, peak urinary flow increased by 38%, prostate volume decreased by 20%, postvoid residual volume decreased by 30 mL, and IIEF score increased by 0.5 point (all differences were significant at P < .01). These changes were sustained throughout the observation period. There was one major complication: Intraluminal necrotic tissue attached to the bladder, which was removed with simple surgery and did not necessitate wall reconstruction. CONCLUSION: PAE is a safe and effective procedure, with low morbidity, no sexual dysfunction, and good short- and intermediate-term symptomatic control associated with prostate volume reduction.

RESUMO

PURPOSE: This study was designed to compare baseline data and clinical outcome between patients with prostate enlargement/benign prostatic hyperplasia (PE/BPH) who underwent unilateral and bilateral prostatic arterial embolization (PAE) for the relief of lower urinary tract symptoms (LUTS). METHODS: This single-center, ambispective cohort study compared 122 consecutive patients (mean age 66.7 years) with unilateral versus bilateral PAE from March 2009 to December 2011. Selective PAE was performed with 100- and 200-µm nonspherical polyvinyl alcohol (PVA) particles by a unilateral femoral approach. RESULTS: Bilateral PAE was performed in 103 (84.4 %) patients (group A). The remaining 19 (15.6 %) patients underwent unilateral PAE (group B). Mean follow-up time was 6.7 months in group A and 7.3 months in group B. Mean prostate volume, PSA, International prostate symptom score/quality of life (IPSS/QoL) and post-void residual volume (PVR) reduction, and peak flow rate (Qmax) improvement were 19.4 mL, 1.68 ng/mL, 11.8/2.0 points, 32.9 mL, and 3.9 mL/s in group A and 11.5 mL, 1.98 ng/mL, 8.9/1.4 points, 53.8 mL, and 4.58 mL/s in group B. Poor clinical outcome was observed in 24.3 % of patients from group A and 47.4 % from group B (p = 0.04). CONCLUSIONS: PAE is a safe and effective technique that can induce 48 % improvement in the IPSS score and a prostate volume reduction of 19 %, with good clinical outcome in up to 75 % of treated patients. Bilateral PAE seems to lead to better clinical results; however, up to 50 % of patients after unilateral PAE may have a good clinical outcome.

RESUMO

INTRODUCTION: Female sexual dysfunction (FSD) in peripheral polyneuropathies besides diabetes mellitus is still a poorly studied subject. Little is known about sexual function in women with amyloidosis, Guillain-Barré syndrome, or porphyria. Even for the world's most common peripheral polyneuropathies such as diabetes mellitus, knowledge and consensus are still lacking. Familial amyloidotic polyneuropathy (FAP) is the most common cause of genetic systemic amyloidosis, with neurological clinical manifestations similar to diabetes mellitus. Until today, no study on the sexual function of these young female patients has been published. AIM: To evaluate FSD in female FAP patients and to compare the results with those of healthy, non-FAP females. METHODS: A questionnaire-based, observational study comprising 94 nonmenopausal women with a sexual partner (51 FAP and 43 non-FAP as the control group) was conducted. The Female Sexual Function Index (FSFI)--Portuguese-validated version was used to assess FSD. MAIN OUTCOME MEASURES: Total and subscales scores of the FSFI. RESULTS: FSD was reported by 42% (95% confidence intervals [CI] 28.3-55.7) of FAP patients compared to 12% of healthy controls. Of all the FAP patients, 39.2% reported problems with desire (95% CI 25.6-52.4), 72.5% reported problems with arousal (95% CI 60.2-84.8), 68% reported lubrication problems (95% CI 55.1-80.9), 62% reported orgasm problems (95% CI 48.5-75.5), 39.2% experienced pain (95% CI, 25.8-52.6), and 49% experienced sexual dissatisfaction (95% CI, 35.3-62.7). Even after multiple logistic regression analysis, FAP is associated with sexual dysfunction in women (OR 4.3, 95% CI 1.2-15.5, P < 0.03), and the affected domains are desire (OR 5.1, 95% CI 1.3-19.7, P < 0.02), arousal (OR 4.7, 95% CI 1.5-14.1, P < 0.007), orgasm (OR 5, 95% CI 1.6-16, P < 0.007), and sexual satisfaction (OR 4.8, 95% CI 1.4-16.9, P < 0.02). Only the use of medication with potential for sexual dysfunction was found as a significant predictor of orgasm disorder (OR 4.2, 95% CI 1.1-15.6, P < 0.03), as did age for sexual dissatisfaction (OR 1.1, 95% CI 1.0-1.2, P < 0.04). CONCLUSIONS: FAP as a peripheral polyneuropathy results in FSD, presenting a risk factor four times greater and related to disease severity in terms of desire, arousal, and orgasm disorders, as well as sexual dissatisfaction.

RESUMO

OBJECTIVE: To compare the efficacy and adverse effects of intramuscular etofenamate and intramuscular diclofenac in the relief of acute renal colic. PATIENTS AND METHODS: A multicentre, randomised, single-blind study was performed in 119 patients admitted to the emergency room for renal colic. Patients were assigned to treatment with either etofenamate 1000mg or diclofenac 75mg, both administered intramuscularly. Pain was self-assessed using a 4-point verbal rating scale (VRS) and a visual analogue scale (VAS) just before drug administration and 30, 60, 120 and 240 min later. RESULTS: The two groups were similar with regard to baseline characteristics. The percentages of patients who reported an improvement in the VRS at 60 min post-administration (primary variable) were 84.5% with etofenamate and 83.3% with diclofenac (p = 0.73). At the other timepoints (30, 120 and 240 min), the proportions of patients improved were, respectively, 69.5%, 82.6% and 79.3% in the etofenamate group, and 75.0%, 81.7% and 80.0% in the diclofenac group. The VAS score showed a statistically significant improvement in both groups, but no differences between groups were found.Analgesic rescue medication was required by 11 (18.6%) patients in the etofenamate group and by 12 (20.0%) patients in the diclofenac group. Mild to moderate adverse events were reported by 3.4% of patients receiving etofenamate and by 5.0% of patients receiving diclofenac. CONCLUSION: Etofenamate and diclofenac were similarly effective and tolerated in the relief of acute renal colic.
