RESUMO
INTRODUCTION: Artificial intelligence (AI) shows immense potential in medicine and Chat generative pretrained transformer (ChatGPT) has been used for different purposes in the field. However, it may not match the complexity and nuance of certain medical scenarios. This study evaluates the accuracy of ChatGPT 3.5 and 4 in providing recommendations regarding the management of postprostatectomy urinary incontinence (PPUI), considering The Incontinence After Prostate Treatment: AUA/SUFU Guideline as the best practice benchmark. MATERIALS AND METHODS: A set of questions based on the AUA/SUFU Guideline was prepared. Queries included 10 conceptual questions and 10 case-based questions. All questions were open and entered into the ChatGPT with a recommendation to limit the answer to 200 words, for greater objectivity. Responses were graded as correct (1 point); partially correct (0.5 point), or incorrect (0 point). Performances of versions 3.5 and 4 of ChatGPT were analyzed overall and separately for the conceptual and the case-based questions. RESULTS: ChatGPT 3.5 scored 11.5 out of 20 points (57.5% accuracy), while ChatGPT 4 scored 18 (90.0%; p = 0.031). In the conceptual questions, ChatGPT 3.5 provided accurate answers to six questions along with one partially correct response and three incorrect answers, with a final score of 6.5. In contrast, ChatGPT 4 provided correct answers to eight questions and partially correct answers to two questions, scoring 9.0. In the case-based questions, ChatGPT 3.5 scored 5.0, while ChatGPT 4 scored 9.0. The domains where ChatGPT performed worst were evaluation, treatment options, surgical complications, and special situations. CONCLUSION: ChatGPT 4 demonstrated superior performance compared to ChatGPT 3.5 in providing recommendations for the management of PPUI, using the AUA/SUFU Guideline as a benchmark. Continuous monitoring is essential for evaluating the development and precision of AI-generated medical information.

BACKGROUND: Sickle cell disease is the most common genetic hemoglobinopathy globally and systemically affects body functioning, decreasing exercise capacity. OBJECTIVE: To assess exercise capacity through the 6-minute walk test (6MWT) and biomarkers in children and adolescents with sickle cell disease. MATERIALS AND METHODS: Cross-sectional study involving 20 children and adolescents from Brazil. Demographic and socioeconomic data were obtained. Baseline measurements included biomarkers (red blood cells, hemoglobin, hematocrit, white blood cells, platelets, reticulocytes, lactate dehydrogenase, creatine phosphokinase, C-reactive protein, interleukin 6, and fetal hemoglobin). The following data were obtained before, during, and after the 6MWT: heart rate, blood pressure, and peripheral oxygen saturation. RESULTS: Eighteen children and adolescents ages 5-14 years old were analyzed, 61.1% boys, 100% black or brown, and 61.1% in primary education, with low household income. The average distance walked in 6MWT was 463.8 (137.7) m, significantly less than the predicted value (P < .001). The distance of 6MWT was associated positively with age (P = .042) and inversely with reticulocyte count (P = .42) and interleukin 6 (P = .00). Age modified the effect of interleukin 6 in younger children (P = .038). CONCLUSION: Our findings suggest increased baseline levels of biomarkers of hemolysis and inflammation impact on 6MWT performance.

INTRODUCTION: Prevention of attacks is a major goal in management of patients with hereditary angioedema (HAE). We aimed to investigate the effects of a systematic intervention for HAE patients. METHODS: Thirty-three patients with HAE with C1-inhibitor deficiency, belonging to a single family, participated in a management program coordinated by an allergist/immunologist. Angioedema attacks before intervention were ascertained by interviews and emergency room charts and recorded prospectively by patients or caregivers after enrollment. Mean number of attacks/month was compared at 12 months preintervention and 8 and 14 months within intervention. Patient-reported outcome instruments were used to assess quality of life, including HAE Quality of Life (HAE-QoL) questionnaire, psychological conditions, and work impairment, at baseline and 8 and 14 months within intervention. Data were stored in REDCap platform and analyzed by adjusted Bayesian models of double Poisson regression. RESULTS: Mean number of attacks/month significantly decreased (95% credible interval [CrI] excluding 0) from 1.15 preintervention to 0.25 and 0.23, 8 and 14 months within intervention, with mean decreases of -0.89 (95% CrI: -1.21 to -0.58) and -0.92 (95% CrI: -1.22 to -0.60), respectively. HAE-QoL scores showed mean total increases of 15.2 (95% CrI: 1.23-29.77) and 26 (95% CrI: 14.56-39.02) at 8 and 14 months within the study, as compared to baseline, revealing marked improvement in quality of life. Significant increase in role-emotional and reduction of depression, stress, and anxiety were observed at 14 months. CONCLUSION: A systematic approach integrating HAE-specific care with effective handling of psychological issues decreased the number of attacks and improved quality of life, targets for best practice in HAE.

BACKGROUND: Epidemiological features of spinal cord injury (SCI) have been changing over the last decades. We evaluated the contemporary trends in the epidemiology of traumatic SCI patients from a rehabilitation center. METHODS: In a cross-sectional study, a consecutive series of 348 patients with traumatic SCI were evaluated. Variables were collected through an epidemiological form, which included gender, age at injury, duration and cause of SCI. We investigated SCI epidemiological trends over time including the association between gender and age at injury with SCI features such as etiology, injury severity and level. RESULTS: The mean age at SCI has increased from 26.0 ± 11.8 in patients with SCI before 2003 to 37.9 ± 15.7 in those with SCI after 2009 (p < 0.001). Gunshot wounds were the main cause of injury in patients with SCI before 2003, dropping from 40.6 to 16.9% after 2009 and being surpassed by road traffic injuries (38.6%) and falls (31.4%) after 2009 (p < 0.001). Gender, SCI severity and level have not changed significantly over the time. CONCLUSIONS: There was a major increase in the average age of patients as well as changes in the etiology of SCI over the past fifteen years, including a significant decrease in gunshot wounds and an increase in the frequency of road traffic injuries and falls. These changes and accompanying risk factors must be taken into consideration when planning measures to prevent SCI.

PURPOSE: After radical prostatectomy (RP), it is rarely acknowledged that several sexual dysfunctions can arise. These include issues in the orgasmic domain (e.g., decreased orgasm intensity, dysorgasmia), problems with ejaculation (e.g., absence of ejaculation), the development of penile deformities, and low sexual desire. This article aims to report the occurrence of orgasmic and ejaculatory dysfunction when actively investigated, documenting those rates and characterizing specific features of these conditions following RP. METHODS: This study has analyzed retrospective data from men who underwent RP and were experiencing erectile dysfunction. During a structured visit, patients were systematically questioned about dysorgasmia, altered orgasmic sensation, climacturia, and arousal incontinence. Continuous variables were analyzed using the Student T or ANOVA tests, while categorical variables were analyzed using Chi-squared or Fisher's exact tests. The associations were described as odds ratios with precise confidence intervals. All tests were two sided; a p value < 0.05 was considered statistically significant. RESULTS: Sixty patients were included, out of which 3 (5%) reported dysorgasmia, while 33.3% presented a decrease in orgasm intensity. Climacturia was reported as the most common orgasmic disorder in 40 (66.6%) patients. However, only 14 patients (35%) reported that it frequently occurs, i.e., more than half of the time. Among the patients who reported climacturia, 72.5% classified it as mild losses. Additionally, arousal incontinence (AI) was noted in the study by 19 (26.3%) patients. CONCLUSION: Our study highlights the importance of discussing orgasmic dysfunctions after RP, which can be frequent and bothersome but are often overlooked in preoperative counseling.
RESUMO
BACKGROUND: Adopting advanced digital technologies as diagnostic support tools in healthcare is an unquestionable trend accelerated by the COVID-19 pandemic. However, their accuracy in suggesting diagnoses remains controversial and needs to be explored. We aimed to evaluate and compare the diagnostic accuracy of two free accessible internet search tools: Google and ChatGPT 3.5. METHODS: To assess the effectiveness of both medical platforms, we conducted evaluations using a sample of 60 clinical cases related to urological pathologies. We organized the urological cases into two distinct categories for our analysis: (i) prevalent conditions, which were compiled using the most common symptoms, as outlined by EAU and UpToDate guidelines, and (ii) unusual disorders, identified through case reports published in the 'Urology Case Reports' journal from 2022 to 2023. The outcomes were meticulously classified into three categories to determine the accuracy of each platform: "correct diagnosis", "likely differential diagnosis", and "incorrect diagnosis". A group of experts evaluated the responses blindly and randomly. RESULTS: For commonly encountered urological conditions, Google's accuracy was 53.3%, with an additional 23.3% of its results falling within a plausible range of differential diagnoses, and the remaining outcomes were incorrect. ChatGPT 3.5 outperformed Google with an accuracy of 86.6%, provided a likely differential diagnosis in 13.3% of cases, and made no unsuitable diagnosis. In evaluating unusual disorders, Google failed to deliver any correct diagnoses but proposed a likely differential diagnosis in 20% of cases. ChatGPT 3.5 identified the proper diagnosis in 16.6% of rare cases and offered a reasonable differential diagnosis in half of the cases. CONCLUSION: ChatGPT 3.5 demonstrated higher diagnostic accuracy than Google in both contexts. The platform showed satisfactory accuracy when diagnosing common cases, yet its performance in identifying rare conditions remains limited.

INTRODUCTION: Phimosis is defined as the inability to retract the foreskin, preventing partial or complete exposure of the glans. OBJECTIVES: To compare the efficacy of topical treatment with betamethasone alone and in combination with hyaluronidase, evaluate systemic absorption of cortisol, and identify factors that predispose the success of topical treatment of phimosis in children aged 3-10 years. METHODS: This randomized double-blinded clinical trial involved 152 participants (3-10 years old) with phimosis. The children were divided into two groups: betamethasone associated with hyaluronidase (betamethasone valerate 2.5 mg + hyaluronidase 150 UTR; Group A) and betamethasone (betamethasone valerate 2.5 mg; Group B). Parents were instructed on how to use the ointment (twice a day, after hygiene, for 60 days) and on collecting salivary cortisol measurements at 11pm and 9am, before and after treatment. Participants were evaluated after 30 and 60 days. Fisher's exact test and paired t-test were used to analyze the data. RESULTS: Ninety children (69.77%) were successfully treated with the proposed treatment, with the success rate for Group A being 75.38% versus 64.06% for Group B, p = 0.18). Systemic absorption evaluated by salivary cortisol did not show differences after the intervention (p > 0.05), indicating that there was no systemic absorption when using ointments with or without hyaluronidase. The factors of age (OR = 0.98 - CI: 0.97-1.00), adherence (OR = 1.49 - CI: 0.53-4.16), balanoposthitis (OR = 1.85 - CI: 0.47-7.19), and previous use of corticosteroids (OR = 1.21 - CI: 0.53-2.72) also did not show influenced results CONCLUSION: Topical therapy for true phimosis with betamethasone 0.2% + hyaluronidase, despite showing no differences when compared with betamethasone 0.2% alone, for a period of up to 60 days, proved to be safe, effective, and with good results. The variables analyzed could not predict the expected clinical response. REBEC: RBR-76bhgyb.
RESUMO
INTRODUCTION: Neoadjuvant cisplatinbased combination chemotherapy (NAC) followed by radical cystectomy is the standard of care for cisplatin-fit patients harboring muscle-invasive bladder cancer (MIBC). Prediction of response to NAC is essential for clinical decision-making regarding alternatives in case of non-response and bladder-sparing in case of complete response. This research aimed to assess the performance of machine learning in predicting therapeutic response following NAC treatment in patients with MIBC. METHODS: A systematic review adhering to the PRISMA guidelines was conducted until July 2023. The study integrated articles relating to artificial intelligence and NAC response in MIBC from various databases. The quality of articles was evaluated using the Quality Assessment Tool for Diagnostic Accuracy Studies 2 (QUADAS-2). A meta-analysis was subsequently performed on selected studies to determine the sensitivity and specificity of machine learning algorithms in predicting NAC response. RESULTS: Of 655 articles identified, 12 studies comprising 1523 patients were included, and four studies were eligible for meta-analysis. The sensitivity and specificity of the studies were 0.62 (95% confidence interval [CI] 0.50-0.72) and 0.82 (95% CI 0.72-0.89), respectively, with a heterogeneity score (I2) of 38.5%. The machine learning algorithms used computed tomography, genetic, and anatomopathological data as input and exhibited promising potential for predicting NAC response. CONCLUSIONS: Machine-learning algorithms, especially those using computed tomography, genetic, and pathologic data, demonstrate significant potential for predicting NAC response in MIBC. Standardization of methodologic data analysis and response criteria are needed as validation studies.
RESUMO
OBJECTIVE: To evaluate handgrip strength (HGS) as a diagnostic tool for frailty risk in elderly patients with asthma, as well as to investigate the prevalence of frailty in this population. METHODS: This was a cross-sectional study including 96 patients ≥ 60 years of age diagnosed with moderate to severe asthma and treated at a tertiary referral center in Brazil. We measured HGS using a calibrated hydraulic hand dynamometer. We used a frailty scale and the AUC to assess the diagnostic accuracy of the HGS test. RESULTS: The median age of participants was 67 years. Most (78%) were women and non-White (91%) of low socioeconomic status. HGS identified those at risk for frailty, with an AUC of 71.6% (61.5-80.4%; p < 0.002), as well as a sensitivity of 73.58% and a specificity of 67.53%, on the basis of a cutoff of ≤ 19 kgf. CONCLUSIONS: HGS appears to be a simple, reliable tool for clinicians to determine frailty risk in older asthma patients in a point-of-care setting.

OBJECTIVE: To investigate the VEGF expression and collagen deposition using a latex biomembrane as bladder replacement in rabbits. MATERIALS AND METHODS: After partial cystectomy, a patch of a non-vulcanized latex biomembrane (2 x 2 cm) was sewn to the bladder of rabbits with 5/0 monofilament polydioxanone sulfate sutures in a watertight manner. Groups of 5 animals were killed at 15, 45 and 90 days after surgery and the bladder was removed. Sections of 5µm were cut and stained with picrosirius-red in order to estimate the amount of extracellular matrix in the graft. To confirm the presence of VEGF in tissues, protein expression was determined by immunohistochemistry. RESULTS: No death, urinary leakage or graft extrusion occurred in any group. All bladders showed a spherical shape. A progressive reduction in the amount of collagen occurred in the graft area and was negatively and linearly correlated with time (p < 0.001). VEGF expression was higher in grafted areas when compared to controls at 15 and 45 days after surgery and decreased with time (p < 0.001). CONCLUSION: The latex biomembrane as a matrix for partial bladder replacement in rabbits promotes temporary collagen deposition and stimulates the angiogenic process.

INTRODUCTION: Electrical nerve stimulation is one of the most commonly used and well-tolerated treatments for overactive bladder (OAB); however, different studies have used different instruments to assess patients' response to treatment. OBJECTIVE: To analyze agreement between use of the visual analogue scale (VAS) and the Dysfunctional Voiding Scoring System (DVSS) for assessing improvement in urinary symptoms following electrical nerve stimulation treatment in children and adolescents with OAB. STUDY DESIGN: A cross-sectional analytical study including children and adolescents of 4-17 years of age diagnosed with OAB who underwent 20 sessions of transcutaneous (TENS) or percutaneous (PENS) electrical nerve stimulation. The DVSS and the VAS were used to assess daytime urinary symptoms before and following treatment. While the DVSS was always applied by a physician, the VAS was applied separately by a physiotherapist and then by a physician. Treatment was considered successful when the DVSS score was zero and the VAS score was ≥90%. Correlations between post-treatment VAS and DVSS scores were evaluated using the kappa coefficient. The VAS scores evaluated by the different professionals were compared for agreement using intraclass correlation and the Bland-Altman plot. RESULTS: Data from 49 cases were available for analysis. Of these, 27 (55.1%) were girls. Mean age was 7.1 ± 2.6 years. There was agreement between the two instruments used, the DVSS and the VAS, in 36/49 patients (73.5%), with a moderate Kappa of 0.44. There was moderate agreement between the VAS scores applied by the two different professionals. DISCUSSION: imitations of the present study include the small sample size and the fact that the inter-observer evaluation was conducted following a single sequence, i.e. all the patients were first evaluated by the physiotherapist and then by the physician, which may have biased answers and the post-treatment VAS scores. Furthermore, although the child participated actively in completing the questionnaires, in cases of divergent answers, the questions were redirected to the responsible adult, and the final answer may not fully represent the patient's true situation. CONCLUSION: The present study found moderate agreement between the DVSS and the VAS, and moderate agreement between VAS scores when the instrument was applied by two different professionals. Although both tools appear to be important, and possibly complementary, a DVSS score of zero precludes the need to apply the VAS.

Frailty assessment has been identified as critical approach in chronic respiratory diseases with substantial impact in the health status and functionality in later life. Aging modifies the immune response leading to a chronic pro-inflammatory state and increased susceptibility to airway infections. Since epigenetic changes, airway epithelium dysfunction and inflammatory cytokine activity seem to be more pronounced in the immunosenescence, elderly asthmatics are at higher risk of poor clinical outcomes. Therefore, we hypothesize that frailty would be associated with the degree of asthma control in elderly patients with moderate to severe asthma. The aims of this study are to investigate association between frailty and asthma control in patients over 60 years old to estimate the prevalence of frailty in this study population. We plan to conduct a cross-sectional study with at least 120 patients above 60 years old with diagnostic of moderate to severe asthma according to Global Initiative for Asthma (GINA) guidelines, treated at a referral outpatient clinic. We defined asthma control by the six-domain Asthma Control Questionnaire (ACQ-6) and frailty phenotype in accordance with Fried scale and visual scale of frailty (VS-Frailty). We hope to analyze the multidimensional relationships between frailty and asthma and contribute to innovative therapeutic plans in geriatric asthma.

INTRODUCTION: Adrenocortical carcinoma (ACC) is diagnosed in paediatric patients at 5 months after symptom onset on average, and 38% die during the first 2.5 years of follow-up. This study aimed to compare the accuracy of Weiss, Van Slooten, and Wieneke histopathological ACC classifications for predicting follow-up prognosis in a paediatric population. METHODS: Data were retrieved from medical records of 57 patients aged <18 years who underwent surgical treatment for ACC with surgical follow-up over 6 months or death due to ACC. They were classified into either good (without recurrence/death due to ACC) or poor (with recurrence/death due to ACC) prognosis group. Two expert pathologists classified the ACC surgical specimens according to the Weiss, Van Slooten, and Wieneke criteria. RESULTS: The median follow-up duration was 126 (18-225) months in 38 males (66.7%) and 19 females (33.3%) (median age: 3 [1-6.5] years). The good prognosis group was younger than the poor prognosis group (median age: 3 [1.5-6.2] years vs. 5 [2-10] years). Seventeen (29.8%) patients in the poor prognosis group died due to ACC within the first 50 months of surgical follow-up; the earliest death occurred in the fourth follow-up month, and the majority of deaths occurred within 24 months of follow-up. The accuracies of Weiss, Van Slooten, and Wieneke classification systems were 40%, 47%, and 77%, respectively. DISCUSSION/CONCLUSION: The Wieneke classification showed the best accuracy but was not sufficiently precise to establish reliable prognosis for ACC in the paediatric population. The Wieneke classification had approximately 95% sensitivity and negative predictive value.

INTRODUCTION: Enuresis prevalence is approximately 5-15% in children aged 6-7 years. The presence of attention deficit hyperactivity disorder (ADHD) in enuretic children is associated with 3 times greater risk of persistent enuresis. The Multimodal Treatment Study for ADHD (MTA) Swanson, Nolan, and Pelham version IV (SNAP-IV) is one of the most used instruments to evaluate ADHD symptoms, but it is a time-consuming questionnaire. OBJECTIVE: This study aims to compare the accuracy of an easy questionnaire named Short Screening Instrument for Psychological Problems in Enuresis (SSIPPE) to MTA-SNAP-IV in identifying ADHD symptoms in children and adolescents with enuresis. METHODS: ADHD symptoms screening was performed by applying SSIPPE and MTA-SNAP-IV in 160 children and adolescents with enuresis, aged 6-14 years, who regularly attended a specialized clinic for pediatric urology. RESULTS: A total of 153 individuals with enuresis were included in the study (52% males), among them 55 (35.9%) were considered positive for inattention and hyperactivity-impulsivity by the MTA-SNAP-IV. Sensitivity for SSIPPE concerning MTA-SNAP-IV was 85.5%, and specificity was 84.7%, with an overall accuracy of 85% in identifying ADHD symptoms. DISCUSSION: In the present study, we found high accuracy of SSIPPE in relation to MTA-SNAP-IV in identifying ADHD symptoms in the enuretic population, with substantial agreement between instruments. Its sensitivity and specificity were considered high for a screening method. However, there are some limitations. The population studied is composed of a group of children with enuresis, which can lead to an overestimation of the test's accuracy, as the disorder under investigation is more prevalent in this population. This can be explained by the high specificity of the test (84.7%) associated with the fact that the SSIPPE is an instrument tailored for an enuretic population, unlike the MTA-SNAP IV. CONCLUSION: The SSIPPE has proven to be a reliable tool in identifying ADHD symptoms in the enuretic population. In addition to being a quick and easily applicable instrument.

INTRODUCTION: Primary nocturnal enuresis (PNE) affects the quality of life of children and families and may lead to low self-esteem and social isolation. The pathophysiology of enuresis is multifactorial. This systematic review aimed to investigate the relationship between toilet training (TT) and PNE in children and adolescents. METHODS: We searched for articles about TT and PNE in MEDLINE (via PubMed), SCOPUS and WEB of SCIENCE databases. The Preferred Reporting Items for Systematic Reviews (PRISMA) statement was used to guide the systematic review. Prior to the study, the review protocol was registered and approved in PROSPERO under the protocol CRD42021270976. The Risk of Bias in Non-Randomized Studies of Exposures (ROBINS-E) was used to analyze the biases of the select studies. RESULTS: A total of 570 studies were initially selected. Of these, eight articles were included in this systematic review, with a total number of 5990 participants aged between 5 and 18 years diagnosed with PNE. Seven of the eight articles reported that prolonged use of disposable diapers for more than one-year, late initiation of the TT process or non-acceptance of the Assisted Infant TT or Elimination Communication approach, use of coercive approaches, and complete of TT after 24 months of age increase the risk of enuresis. Only one of the selected studies did not find an association between the start of TT after 24 months of age and the presence of isolated PNE. Three studies did not mention the approach used in the TT process. CONCLUSION: Most of the articles reviewed showed that prolonged diaper use, delay in the start or completion of the TT and use of coercive approaches increase the risk of enuresis. On the other hand, one study showed no relationship between the start of TT after 24 months of age and the presence of isolated enuresis.

INTRODUCTION: Ureteropelvic junction obstruction (UPJO) particularly represents a challenge in regard to management, as not all hydronephrosis (HN) represent a kidney-damaging state. Urinary biomarkers have been proposed as noninvasive tools. Extracellular matrix (ECM) proteins are associated with tissue fibrosis in the setting of UPJO and is poorly explored. OBJECTIVE: To investigate whether urinary ECM proteins are useful to discriminate the severity of urinary obstruction on unilateral UPJO. STUDY DESIGN: Children with unilateral UPJO were prospective enrolled. Urinary (u) matrix metalloproteinases (MMP-1,-2,-9 and TIMP-1,-2) as well as clinical characteristics were measured in the following groups: 26 children with obstructive HN at initial diagnosis and after six months of dismembered pyeloplasty; 22 children with non-obstructive HN at diagnosis and after six months of observation; 26 children without any urinary tract condition, as the control group. Results were assessed statistically using for homogenous groups, a one-way analysis of variances (ANOVA) and for nonparametric groups, Mann-Whitney test or Kruskal-Wallis test was performed. ROC curves were performed. RESULTS: Baseline samples demonstrated a higher concentration of uMMP-1/Cr, uMMP-2/Cr, u-TIMP-1/Cr and u-TIMP-2/Cr in obstructive HN group; uMMP-9/Cr levels were higher in non-obstructive HN group and all studied biomarkers had lower concentrations for the control group. On follow-up, for the obstructive HN group, urinary concentration of uTIMP-1/Cr and uTIMP-2/Cr decreased, and uMMP-1/Cr, uMMP-2/Cr and uMMP-9/Cr increased when comparing preoperative to postoperative values. In the non-obstructive HN group, all proteins analyzed were stable after six months of observation. ROC curves analysis showed a promising diagnostic profile for the detection of obstructive HN for uTIMP-1/Cr (area under the curve -AUC-; of 0.692), uTIMP-2/Cr (AUC of 0.678) and for uMMP-2/Cr (AUC of 0.655). DISCUSSION: The severity of kidney obstruction could correlate with the urinary ECM proteins concentration in this study. This is concordant with prior studies demonstrating that a disruption of the balance of accumulation/degradation of the ECM proteins occur on obstructive uropathy. Limitations of our study include the older age of our patients and that these markers had no influence at all on the surgical decision. CONCLUSION: We demonstrate that obstructive HN have significantly higher uMMP-2, uTIMP-1 and uTIMP-2 concentrations. Particularly, uTIMP-2 levels were correlated to severity of obstruction and therefore, it might be a useful urinary biomarker to correctly allocate children with HN between surgical management vs follow-up. After pyeloplasty, uTIMP-1 and uTIMP-2 presented a progressive decrease postoperatively, which is also highly desirable for urinary markers.

BACKGROUND: Toilet training (TT) is an important milestone in child development. The purpose of this review is to summarize the different TT methods found in the literature and determine their effectiveness for the TT process. DATA SOURCES: Articles about toilet training were collected from databases, including PubMed and Scopus. The Preferred Reporting Items for Systematic Reviews (PRISMA) statement was used to guide the systematic review. RESULTS: Two main classifications were used: a child-oriented approach and a structured behavioral approach. Most children were trained by the structured behavioral approach, with early onset, but at the age of completion of TT, similar to those who used a child-oriented approach. Success rates, in the few studies that reported, were better with the child-oriented approach. The lowest reported success rate was the daytime humidity alarm approach. There is no consensus on the best method to be used, as it involves a wide variety of parents' preferences and expectations and cultural differences, with studies showing great heterogeneity and methodological flaws that make meta-analysis unfeasible. CONCLUSIONS: The approaches have not been directly compared, so it isn't possible to make definitive claims about one method's superiority over the other.

Lower urinary tract symptoms (LUTS) are common complaints in the adult male population and have a negative affect in the quality of life and represent an economic burden for the healthcare system worldwide. The International Prostatism Symptom Score (IPSS) is a validated tool for assessing these symptoms, but patients with low literacy may have difficulties comprehending and completing it accurately. The Urgency, Weak Stream, Incomplete Emptying, and Nocturia (UWIN) questionnaire was developed as a shorter tool in the assessment of LUTS to improve accuracy and minimize error. This study aimed at performing cross-cultural adaptation to Brazilian Portuguese and validation of UWIN questionnaire for patients with LUTS. The cross-cultural adaptation followed the steps of conceptual, item, semantic, operational, and pre-test equivalence to obtain the UWIN-Br version. The IPSS (gold standard) and UWIN-Br were coadministered, and information regarding the uroflowmetry examination was also recorded. We evaluated 306 men, median age 59 [52-66] years. There was a positive correlation r = 0.804 (p < 0.001) between the total IPSS score and the total UWIN-Br score, as well as the quality of life question (r = 0.761) (p < 0.001). The Bland-Altman plot showed good agreement between. Also, we observed that the maximum flow values decreased with the severity of the LUTS. UWIN-Br demonstrated excellent diagnostic accuracy in detecting the most severe cases. The area under the ROC curve was 89% [81-97%] 95% CI. 280 (91.5%) subjects completed the questionnaires without help, while 26 (8.5%) did so through an interview. The response time was 1.2 [1.0-1.5] min for UWIN-Br and 2.8 [2.2-3.4] min for IPSS (p < 0.001). UWIN-Br presents satisfactory and similar psychometric properties to the IPSS in the evaluation of LUTS and quality of life and is suitable for use in both clinical practice and research in our country.
RESUMO
OBJECTIVE: To evaluate epidemiological aspects of priapism in patients with sickle cell disease, and these aspects impact on adult sexual function. METHODS: This was a cross-sectional study including individuals with sickle cell disease who were evaluated at a reference center for sickle cell. Participants completed a structured questionnaire about their sociodemographic characteristics and priapism events. Sexual function was assessed using validated two instruments, the Erection Hardness Score and one about the sex life satisfaction. RESULTS: Sixty-four individuals with median aged of 12 (7 to 28) years were interviewed. The prevalence of priapism was 35.9% (23/64). The earliest priapism episode occurred at 2 years of age and the latest at 42 years. The statistical projection was that 71.1% of individuals of the study would have at least one episode of priapism throughout life. Patients with episodes of priapism (10/23) had significantly worse erectile function Erection Hardness Score of 2 [1-3]; p=0.01 and were less satisfied with sexual life 3 [3-5]; p=0.02. CONCLUSION: Priapism is usually present in childhood, and severe episodes are associated with cavernous damage, impairment in the quality of the erection, and lower sexual satisfaction.

OBJECTIVES: To assess the prevalence and interrelationship between lower urinary tract symptoms and sexual dysfunction in men with multiple sclerosis (MS). METHODS: In a cross-sectional study, we evaluated 41 men (mean age 41.1±9.9 years) with MS from February 2011 to March 2013, who were invited to participate irrespective of the presence of lower urinary tract symptoms or sexual dysfunction. Neurological impairment was assessed with the Expanded Disability Status Scale; lower urinary tract symptoms were evaluated with the International Continence Society male short-form questionnaire, and sexual dysfunction was evaluated with the International Index of Erectile Function. All patients underwent transabdominal urinary tract sonography and urine culture. RESULTS: The mean disease duration was 10.5±7.3 years. Neurological evaluation showed a median Expanded Disability Status Scale score of 3 [2-6]. The median International Continence Society male short-form questionnaire score was 17 [10-25]. The median International Index of Erectile Function score was 29 [15-46]. Twenty-nine patients (74.4%) had sexual dysfunction as defined by an International Index of Erectile Function score <45. Voiding dysfunction and sexual dysfunction increased with the degree of neurological impairment (r=0.02 [0.02 to 0.36] p=0.03 and r=-0.41 [-0.65 to -0.11] p=0.008, respectively). Lower urinary tract symptoms and sexual dysfunction also displayed a significant correlation (r=-0.31 [-0.56 to -0.01] p=0.04). CONCLUSIONS: Most male patients with MS have lower urinary tract symptoms and sexual dysfunction. The severity of the neurological disease is a predictive factor for the occurrence of voiding and sexual dysfunctions.
